Description

Technical Field

[0001] The present invention relates to the technical field of screen printing, and specifically to a screen frame for reducing the distortion of screen wires. Background Art

[0002] Screen printing, namely silk screen printing, is a printing technology that leaks ink onto a printing substrate through a silk screen printing plate. Its characteristics include wide applicability, being able to print on printing substrates of different materials, shapes, and sizes, having a thick ink layer and strong covering power, and being able to present rich colors and unique visual effects. In order to facilitate reducing the distortion of screen wires during use, a screen frame for reducing the distortion of screen wires is required.

[0003] A screen frame for reducing the distortion of screen wires refers to a screen frame that adopts a high-stability structure and high-quality materials and has been prestressed. Its design is reasonable, and it can effectively resist the distortion deformation caused by the tension of the silk screen, ensuring that the screen wires remain flat during the printing process, improving the printing accuracy and effect, and is an essential component in screen printing.

[0004] Currently, for the screen frames for reducing the distortion of screen wires on the market, the screen wires are installed on the inner side of the outer frame. When in use, the printing substrate is attached to the screen wires, and then the ink is leaked onto the screen wires for printing. In order to reduce the distortion caused by pressing on the screen wires during printing, the prior art adds an inner frame inside the screen wires. Through the support of the inner frame, it can cooperate with the outer frame to fix the inner and outer sides of the screen wires synchronously, thereby reducing the distortion of the screen wires during use. In order to further reduce the distortion of the screen wires during use and improve stability, the prior art uses steel wires to replace the screen wires of the inner frame to buffer through the strength of the steel wires and reduce the impact of distortion on the screen wires. However, in actual use of this anti-distortion method, the lengths of the screen wires on the four sides and four corners of the square screen frame are inconsistent, which leads to different elasticities of the pressure on the screen wires, making the anti-distortion direction and strength also affected. At the same time, it is difficult to reuse the screen wires after coating with paint, thereby reducing the practicality of the device. Summary of the Invention

[0021] Next, in combination with the accompanying drawings of the specification of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figure 1 、 Figure 3 and Figure 6 , an embodiment of the present invention provides a wire frame for reducing the twist of mesh wires, including an outer frame 1. A cleaning mechanism 2 is arranged inside the outer frame 1. The cleaning mechanism 2 is used to reduce the twist and facilitate cleaning. An assembly mechanism 3 is arranged outside the outer frame 1. The assembly mechanism 3 can assemble the device so that multiple devices can be used synchronously. A positioning mechanism 4 is arranged inside the outer frame 1. The positioning mechanism 4 can make the device applicable to different positions; The cleaning mechanism 2 includes bevel gears 201. A plurality of bevel gears 201 are respectively rotatably connected to the four inner corners of the outer frame 1. The plurality of bevel gears 201 are meshed and connected to each other. Rotating one bevel gear 201 can drive the rotation of the bevel gear 201 on the other side through meshing. A first threaded block 202 is fixedly connected to the outer side of the bevel gear 201. Rotating the bevel gear 201 can synchronously drive the first threaded block 202 thereon to rotate. A moving block 203 is threadedly connected to the outer side of the first threaded block 202. The upper and lower sides of the outside of the moving block 203 are respectively rotatably connected to a first telescopic plate 204. As the first threaded block 202 rotates, it will drive the moving block 203 to move, thereby pushing the first telescopic plate 204 to rotate. A scraper 205 is rotatably connected to the outer side of the first telescopic plate 204. Rotating the first telescopic plate 204 can drive the scraper 205 to move. A wire mesh 208 is arranged in the middle of the inner side of the outer frame 1. An inner frame 207 is fixedly connected to the outer side of the wire mesh 208. A wire 209 is fixedly connected to the outer side of the inner frame 207. The structural strength of the wire 209 can be improved through the inner frame 207 and the wire 209. Arc-shaped clamps 206 are fixedly connected to the four circumferences of the outside of the wire 209. The outer side of the arc-shaped clamp 206 and the wire 209 are fixedly connected to the outer frame 1. The arc-shaped clamp 206 can maintain the uniform stress of the wire 209 through its own shape; Specifically, the cooperation between the inner frame 207 and the inner wire mesh 208 can effectively enhance the structural strength of the wire 209. At the same time, a plurality of arc-shaped clamps 206 fixedly connected to the outer frame 1 can ensure that the distance between the four circumferences of the wire 209 and the outer frame 1 is uniform, so that it deforms synchronously when twisted to reduce the impact on the wire 209. In addition, rotating one of the bevel gears 201 will drive the synchronous rotation of the other plurality of bevel gears 201 through meshing, and then drive the synchronous rotation of the first threaded blocks 202 thereon, prompting the synchronous movement of the moving blocks 203. The moving blocks 203 push the first telescopic plates 204 to move and rotate telescopically, and the first telescopic plates 204 then push the scrapers 205 to move, so that the paint attached to the outer side of the wire 209 can be scraped off after use, enabling the device to be reused.

Through the transmission of the belt 306, when the toothed groove wheel 302 rotates, the rotating wheel 303 can be driven to rotate synchronously. Cross rods 305 are fixedly connected to the right sides of both the toothed groove wheel 302 and the rotating wheel 303. When the toothed groove wheel 302 and the rotating wheel 303 rotate, the cross rods 305 can be driven to rotate synchronously. A threaded column 307 is slidably connected to the outer side of the cross rod 305. The threaded column 307 can rotate along the cross rod 305. The front side at the top of the installation frame 301 is rotatably connected with a circular gear 304. The circular gear 304 is meshed and connected with the toothed groove wheel 302. Rotating the circular gear 304 can drive the toothed groove wheel 302 to rotate. A toothed groove plate 308 is fixedly connected to the outer left side of the outer frame 1. The toothed groove plate 308 is in threaded connection with the threaded column 307. Through the threaded connection between the toothed groove plate 308 and the threaded column 307, multiple devices can be assembled together; Specifically, when rotating the circular gear 304, the toothed groove wheel 302 meshed with it can be driven to rotate. With the transmission of the belt 306, the rotating wheel 303 on the other side will also rotate accordingly. The synchronous rotation of the toothed groove wheel 302 and the rotating wheel 303 can drive the cross rod 305 and the threaded column 307 on it to rotate together. After that, align multiple devices left and right, and move the threaded column 307 along the cross rod 305 to make the threaded column 307 in threaded connection with the toothed groove plate 308. Through this threaded connection method, multiple devices can be assembled together with each other, thereby facilitating the synchronous operation of multiple devices to carry out printing work.

[0024] Refer to Figure 4 , Figure 5 and Figure 8, the positioning mechanism 4 includes a hollow plate 401. Two hollow plates 401 are respectively connected to the front and rear sides of the top of the outer frame 1. A threaded rod 402 is rotatably connected to the inner side of the hollow plate 401. The threaded rod 402 can rotate along the hollow plate 401. A second threaded block 403 is threadedly connected to the outer side of the threaded rod 402. Rotating the threaded rod 402 can drive the second threaded block 403 to move. A second telescopic plate 404 is rotatably connected to the inner side of the second threaded block 403. The bottom of the second telescopic plate 404 penetrates the outer frame 1 and is rotatably connected to a U-shaped rod 405. As the second threaded block 403 moves, it can push the second telescopic plate 404 to push the U-shaped rod 405. The outer side of the U-shaped rod 405 is rotatably connected to the outer frame 1. The U-shaped rod 405 can rotate along the outer frame 1. Dampers 406 are fixedly connected to both the left and right sides of the bottom of the U-shaped rod 405. The bottom of the damper 406 is fixedly connected to a bottom plate 407. The damper 406 can support the bottom plate 407, and the device can be supported through the bottom plate 407; Specifically, when rotating the threaded rod 402 inside the hollow plate 401, the second threaded block 403 will move left and right along the threaded rod 402. As the second threaded block 403 moves, the second telescopic plate 404 will undergo telescopic changes. During the movement and telescoping of the second telescopic plate 404, it will push the U-shaped rod 405 to rotate inside the outer frame 1. The bottom plate 407 at the bottom of the U-shaped rod 405 can thus support the device, and the damper 406 can reduce the impact on the supporting effect of the bottom plate 407 during use. By adjusting the rotation angle of the bottom plate 407, the device can adapt to printing requirements at different positions.

[0025] Refer to Figure 2 , Figure 3 and Figure 7 , the cleaning mechanism 2 further includes telescopic blocks 210. A plurality of telescopic blocks 210 are respectively fixedly connected to the middle of the outer side of the scraper 205.

A plurality of knobs 211 are respectively rotatably connected to the outer periphery of the outer frame 1. The outer side of the knob 211 penetrates the outer frame 1 and is fixedly connected to the corresponding bevel gear 201. Rotating the knob 211 can drive the bevel gear 201 to rotate; the assembling mechanism 3 further includes a connecting rod 309. The connecting rod 309 is rotatably connected to the outer side of the threaded column 307. The top of the connecting rod 309 penetrates the mounting frame 301 and is fixedly connected to a handle 310. By pushing the handle 310, the connecting rod 309 can be moved, thereby pushing the threaded column 307 to move; Specifically, by the expansion and positioning of the expansion block 210, the stability of the scraper 205 during movement can be improved. By rotating the operation knob 211, it is convenient to synchronously drive the bevel gear 201 to rotate to operate the cleaning mechanism 2. By pushing the connecting rod 309 to move with the operation handle 310, the movement of the threaded column 307 along the cross bar 305 can be adjusted, thereby facilitating the insertion of the threaded column 307 into the tooth groove plate 308.

[0026] Referring to Figure 2 , Figure 4 and Figure 8 , the positioning mechanism 4 includes sliding grooves 409. A plurality of sliding grooves 409 are respectively opened on the front and rear sides of the outer parts of the two hollow plates 401. The outer side of the threaded block two 403 is slidably connected to the sliding grooves 409, and the sliding grooves 409 can improve the stability of the movement of the threaded block two 403; a nut 408 is rotatably connected to the outer side of the hollow plate 401, and the outer side of the nut 408 penetrates through the hollow plate 401 and is fixedly connected to the threaded rod 402. Rotating the nut 408 can drive the threaded rod 402 to rotate; Specifically, by the sliding of the sliding grooves 409 and the threaded block two 403, the stability of the threaded block two 403 during movement can be improved. By operating the rotation of the nut 408, it is convenient to operate the rotation of the threaded rod 402.

[0027] Referring to Figure 1 , Figure 2 and Figure 5 , support brackets 7 are fixedly connected to the front and rear sides of the outer part of the outer frame 1, and support plates 8 are fixedly connected to the bottoms of the support brackets 7. The device can be supported by the support brackets 7 and the support plates 8; lifting handles 5 are arranged around the top of the outer frame 1, and screws 6 are threadedly connected to the front and rear sides of the inside of the lifting handles 5. The lifting handles 5 are threadedly connected to the outer frame 1 through the screws 6. The lifting handles 5 installed by the screws 6 can facilitate the handling of the device; Specifically, the firmness of the device after placement and fixation can be improved by the support brackets 7 and the support plates 8 thereon. The lifting handles 5 installed by the screws 6 can facilitate the holding and handling of the device, and the lifting handles 5 can be removed by the screws 6 when not needed.

[0028] Working principle: The inner frame 207 and the inner wire mesh 208 can enhance the structural strength of the wire mesh 209. At the same time, through a plurality of arc-shaped clamps 206 fixed to the outer frame 1, the consistency of the distance between the periphery of the wire mesh 209 and the outer frame 1 can be maintained, so as to maintain the synchronism during twisting, reduce the impact on the wire mesh 209, and by rotating the bevel gear 201, a plurality of bevel gears 201 can be synchronously driven to rotate through meshing, and along with the rotation of the bevel gear 201, the threaded block one 202 thereon can be synchronously driven to rotate, thereby driving the moving block 203 thereon to move synchronously. At this time, along with the movement of the moving block 203, the telescopic plate one 204 can be pushed to move accordingly. Thus, through the rotation and self-expansion and contraction of the telescopic plate one 204, the scraper 205 can be pushed to move accordingly, and the paint attached to the outer side of the wire mesh 209 can be scraped off after use, so that the device can be reused; And by rotating the circular gear 304, the grooved pulley 302 engaged therewith can be driven to rotate. At this time, through the transmission of the belt 306, the rotating wheel 303 on the other side can be driven to rotate. At this time, through the rotation of the grooved pulley 302 and the rotating wheel 303, the cross bar 305 and the threaded column 307 thereon can be synchronously driven to rotate. At this time, multiple devices are aligned left and right, and at the same time, the threaded column 307 is moved along the cross bar 305 to connect the threaded column 307 with the toothed groove plate 308. Thus, multiple devices can be assembled with each other through threaded connection, so as to facilitate the synchronous operation of multiple devices for printing; Finally, by rotating the threaded rod 402 along the inner side of the hollow plate 401, the threaded block two 403 can be driven to move left and right along the threaded rod 402. At this time, along with the movement of the threaded block two 403, the telescopic plate two 404 can be driven to expand and contract, and along with the movement and self-expansion and contraction of the telescopic plate two 404, the U-shaped rod 405 can be pushed to rotate along the inside of the outer frame 1. Thus, the device is supported by the bottom plate 407 at the bottom of the U-shaped rod 405, and the impact on the support of the bottom plate 407 during use is reduced through the damper 406. Thus, the device is adapted to printing at different positions by adjusting the rotation of the bottom plate 407.
