Device for applying a pattern on the long, narrow products
(57) Abstract:Usage: for application of the pattern by a stream of abrasive material from mirrors and flat glass products. The device comprises a frame fixed on the base plate, and on the rack, a removable screen frame. Racks have longitudinal and transverse ribs, as well as Windows and frames - rollers with annular grooves for transferring frames from one edge to the other lateral edge. In the area of the base plate is fixed against each other immovable and movable spring-loaded plate with radial notches, one notch is displaced towards the base plate from the axis of symmetry of the stand. 3 C.p. f-crystals, 7 Il. The invention relates to a device for applying a pattern on a flat glass or mirror long and narrow shape.A device for applying a pattern on a sheet article containing the stencil with Windows for applying through their emphasis on the product, is attached to the chassis base plate and the tabs working position products and stencil.The known device is inconvenient to use when drawing a pattern on a long narrow items, and therefore it is inefficient. The device is difficult and cumbersome, it has large, the envelope is passed and narrow products and reducing the size of the device.The technical result is to increase productivity and reduce cost of the device.This objective is achieved in that the device for applying a pattern on the long, narrow products containing frame attached to it the support plate, the tabs working position products and stencil having a window for applying through their emphasis on the product stream of abrasive material, a frame provided with upper and lower drive removable frames with stencils, made in the form attached to the frame above and below the support plate and located behind and at right angles to it cross rails, with stencils mounted on the framework having vertical ends of the rollers, and a rack provided with vertical guides with Windows posted on transverse guides on the distances vertically, equal to the distances between the rollers framework to translate them from vertical to transverse rails drive removable frames.The problem is solved also by the fact that the guides are made in the form of ribs, and the rollers are each made with an annular groove to compose them to interact with the said ribs, transverse rails sloped down otouto on vertical posts, located at distances equal to the distances between the rollers and frames against them mounted spring-loaded plate made with the same cut with a common center with a notch on the rack and the adjacent top and bottom bevels.New features not known from the prior art, and the device is industrially feasible. This allows us to consider that the technical solution involves an inventive step and meets the criteria of the invention.In Fig. 1 shows a device for applying a pattern on a long narrow items, front view; Fig. 2 - the same, lateral view; Fig. 3 - section a-a in Fig. 1, illustrates the interaction of the stencil with the product of Fig. 4 - node I in Fig. 2 shows the drive removable frames; Fig. 5 - section b-B in Fig. 4 shows the roller screen frame of Fig. 6 - node II in Fig. 2, showing the latch operating position of the screen frame; Fig. 7 - section b-b of Fig. 6.The device comprises a frame 1, a support plate 2 and the screen frame 3.The frame is made in the form of the front 4 and rear 5 struts connected below the support bars 6. The front rack to the rear are connected by cross bars 7, and the front and rear of the rack laterally connected tilted down toward rear ststion. On the rear edge and part of the rear wall of each rack is formed by four window 12, the top of which is located above the inclined edges so that their bottom edges were in the plane of the upper faces of the ribs. In the area of the mounting base plate on each rack in the plane of its edges fixed spaced vertically on the two plates 13 with rounded neckline 14 each and are mounted opposite the strap 15 with the groove 16. In each strip installed movable plate 17 with a similar cutout 18 and the stop 19. The plate has a top and bottom cut bevels 20 and placed so that the cut had in the working position of the overall center. The plate 17 is held in working position by a tension spring 21. The base plate bottom and one side has the support pins 22, the height of which does not exceed the thickness of the product (glass). Each screen frame with the sides is installed on the axis 23 of the rollers 24, each of which is formed on its forming the annular groove 25. The rollers are placed at a distance equal to the distance between the Windows 12 stands for translation replaceable part on the drives (ribs 8 or 9). Each frame is fixed elastic stencil plate 26 made of at least a single layer of material, which formed about The operator sets the complete set of replaceable part 3 ring grooves 25 of the roller 24 (top) on the upper transverse ribs 8, the extreme of which is based in the stop 29, and sets the pins 22 of the base plate 2 of article 28. To install the screen plate 26 in the working position of the operator of the front frame 3 rolls rollers 24 on the upper transverse ribs 8 in the direction of the front pillars 4. The rollers 24 through the Windows 12 are transferred to the edge 10 of the uprights 4 and move the bracket 30 down, the rollers 24, based on the bevels 20 and, overcoming the resistance of the plate spring 21, the pushing plate 17 and come into radial openings 14 and 18. Since the cutout 14 of the fixed plate 13 is displaced from the symmetry axis of the rack 4 in the direction of the support plate 2, frame 3 spring plate 17 is moved toward the base plate, and the resilient stencil plate 26 is firmly tightened to the product 28. After that the gun sandblasting unit (not shown) the operator through the window 27 on the stencil plate 26 causes a jet of abrasive material pattern on the workpiece in a known manner. After that, the operator bracket 30 moves the frame further down, overcomes the resistance of spring 21, and outputs the rollers of the radial cut through the bottom of the window 12 of the uprights 4 displays the rollers on neither="ptx2">The use of the invention allows to simplify the design and technology application of the pattern on the product. 1. DEVICE FOR APPLYING a PATTERN ON the LONG, NARROW PRODUCTS containing frame attached to it the support plate, the tabs working position products and stencil with Windows for applying through their pattern on the product mainly stream of abrasive material, characterized in that it is provided with top and bottom drive removable frames with stencils, made in the form attached to the frame respectively above and below the support plate transverse rails perpendicular to the base plate, while the scope of the stencils have at their vertical ends of the rollers, and the rack frame are provided with vertical guides Windows above the transverse guides on the vertical distance equal to the distance between the rollers.2. The device under item 1, characterized in that the guides are made in the form of ribs, and the rollers are provided with annular grooves to compose them to interact with the ribs.3. The device according to PP.1 and 2, characterized in that the lateral guides are inclined relative to the horizontal plane.

SUBSTANCE: material for printing forms is made only from film of thermo-plastic resin by usage of polyether film in such a way, that aperture, through which paint may permeate, can be thermally perforated without increasing power of thermo-printing head. Film is a thermo-sensitive material for stencil printing forms 12, having given thickness, and consists of stretched mylar film or stretched film with low melting point, produced by copolymerization of polyethylene therephthalate and polybutylene therephthalate. A set of smallest raster cells 14 is formed on one side of film by transfer of template. Transfer of template may be performed under working pressure 104·102(m-t)/(m-g) Pascals or higher, when working temperature is t°C, melting point temperature of film is m(°C), and temperature of film vitrifying is g(°C).
EFFECT: decreased power of thermo-printing head, facilitated operations with film.
