[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Example 1:

[0053] like Figures 1 to 5As shown, this utility model provides a filter screen pressing device, including: a base 1 and an extrusion structure arranged on the base 1 for pressing a metal filter screen, and a support structure arranged on the extrusion structure for holding and supporting the metal filter screen.

[0054] The extrusion structure includes a support frame 2 arranged above the base 1, a cylinder 201 arranged above the support frame 2, a mounting plate 202 arranged on the output end of the cylinder 201 for moving up and down with the output end of the cylinder 201, pressure plates 203 and 204 arranged below the mounting plate 202, a slide rod 205 slidably installed inside the mounting plate 202, a relief plate 206 arranged below the slide rod 205, an auxiliary spring 207 arranged between the mounting plate 202 and the relief plate 206, the auxiliary spring 207 being movably sleeved on the slide rod 205, and a filter screen 208 located below the pressure plates 203 and 204, movably installed inside the base 1 and located below the filter. The U-shaped plate 209 below the mesh 208 is driven by the cylinder 201, which controls the mounting plate 202 to descend. The descending mounting plate 202 will drive the pressure plate 1 203, pressure plate 204, relief plate 206, filter screen 208 and positioning support plate 3 to descend. The descending filter screen 208 will contact one end of the U-shaped plate 209, and at the same time, the relief plate 206 will press the filter screen 208 onto the U-shaped plate 209. The pressure plate 1 203 and pressure plate 204 continue to descend, pressing one side of the filter screen 208 toward the surface of the base 1 and pressing the other side of the filter screen 208 into the U-shaped plate 209, so that the contact position between the filter screen 208 and the U-shaped plate 209 is inverted U-shaped, thus completing the pressing operation.

[0055] The support structure includes a positioning plate 3 arranged below the mounting plate 202, a positioning slot 301 opened inside the positioning plate 3, a filter screen 208 movably installed in the positioning slot 301, a limiting rod 302 slidably installed in the positioning slot 301 and in contact with one side of the filter screen 208 to limit the insertion depth of the filter screen 208, and an adjusting component arranged on the limiting rod 302 to adjust the position of the limiting rod 302. When the filter screen 208 is pressed, it can be inserted into the positioning slot 301. One end of the filter screen 208 will be blocked by the limiting rod 302 to limit the insertion depth. The positioning plate 3 supports the filter screen 208.

[0056] Specifically, the adjustment assembly includes a screw 303 threadedly installed inside the positioning plate 3 and rotatably installed inside the limit stop 302, and two retaining rings 304 located on both sides of the limit stop 302. Both retaining rings 304 are fixedly sleeved on the screw 303. Rotating the screw 303 will cause it to move through the threaded engagement with the positioning plate 3, so that the screw 303 drives the retaining rings 304 to rotate and move. The moving retaining rings 304 will cause the limit stop 302 to slide inside the positioning slot 301, thereby adjusting the position of the limit stop 302.

[0057] The support structure also includes a limiting component arranged in the positioning slot 301 to limit the horizontal position of the filter screen 208 in the positioning slot 301.

[0058] Specifically, the limiting component includes a positioning block 305 and a threaded seat 306 slidably installed inside the positioning slot 301. The positioning block 305 is arranged on one side of the threaded seat 306. A screw 307 is threaded inside the threaded seat 306 and rotatably installed in the positioning support plate 3. Rotating the screws 307 on both sides causes the threaded seat 306 to slide through the threaded engagement with the threaded seat 306. The threaded seat 306 can then drive the positioning block 305 to slide, thereby adjusting the position of the positioning block 305. The positioning blocks 305 on both sides can limit the horizontal position of the filter screen 208 and position it.

[0059] Example 2:

[0060] Based on Example 1, in order to facilitate the use of U-shaped plates 209 of different sizes, a positioning structure for limiting the position of the pressing parts is arranged on the base 1.

[0061] The positioning structure includes an installation groove 4 inside the base 1, a positioning clamping rod 401 slidably installed in the installation groove 4 and in contact with one side of the U-shaped plate 209 for pressing down the U-shaped plate 209, a connecting rod 402 slidably installed inside the base 1, the connecting rod 402 being arranged on one side of the positioning clamping rod 401, and a pull rod 403 arranged at one end of the connecting rod 402. Pulling the pull rod 403 causes the connecting rod 402 to move, which in turn causes the positioning clamping rod 401 to move. The moving positioning clamping rod 401 compresses the limiting spring 404. At this time, the U-shaped plate 209 can be placed between the positioning clamping rod 401 and the installation groove 4, and the positioning clamping rod 401 is used to press down the U-shaped plate 209 for fixation.

[0062] The positioning structure also includes a limiting spring 404 movably sleeved on the connecting rod 402 for pressing the positioning clamp rod 401 and pressing it against the U-shaped plate 209. One end of the limiting spring 404 is arranged on one side of the positioning clamp rod 401, and the other end of the limiting spring 404 is arranged on the inner wall of the mounting groove 4. Under the elastic force of the spring, the positioning clamp rod 401 can be pressed, so that the positioning clamp rod 401 can be tightly attached to the U-shaped plate 209, thereby improving stability.

[0063] Working principle: During use, pulling the lever 403 moves the connecting rod 402, which in turn moves the positioning clamp 401. The moving positioning clamp 401 compresses the limit spring 404. At this time, the U-shaped plate 209 can be placed between the positioning clamp 401 and the mounting groove 4. (Refer to...) Figure 2 Position the filter screen 208, then release the pull rod 403. At this time, the limit spring 404 will squeeze the positioning clamp 401, causing the positioning clamp 401 to press on the U-shaped plate 209, thereby fixing the position of the U-shaped plate 209 and adapting to U-shaped plates 209 of different sizes. After installation, the position of the limit stop 302 and the spacing of the positioning blocks 305 on both sides can be adjusted according to the size of the filter screen 208. When adjusting, rotate the screw 303. The screw 303 will move through the thread engagement with the positioning bracket 3, causing the screw 303 to drive the retaining ring 304 to rotate and move. The moving retaining ring 304 will drive the limit stop. 302 slides inside the positioning slot 301, thereby adjusting the position of the limit stop 302. Then, the two screws 307 on both sides are rotated, causing the screws 307 to slide through the threaded engagement with the threaded seat 306. The threaded seat 306 then drives the positioning block 305 to slide, adjusting the position of the positioning block 305. After adjustment, the filter screen 208 to be pressed is inserted into the positioning slot 301 on the positioning tray 3. The filter screen 208 will pass between the two positioning blocks 305 and contact the limit stop 302. The limit stop 302 restricts the insertion depth of the filter screen 208, ultimately forming... Figure 2In this state, the cylinder 201 can be driven to control the mounting plate 202 to descend. The descending mounting plate 202 will drive the pressure plate 1 203, pressure plate 204, relief plate 206, filter screen 208, and positioning support plate 3 to descend. The descending filter screen 208 will contact one end of the U-shaped plate 209, and at the same time, the relief plate 206 will press the filter screen 208 onto the U-shaped plate 209. As the mounting plate 202 continues to descend, it will slide on the slide rod 205 and compress the auxiliary spring 207. The force can cause the relief plate 206 to press the filter screen 208 tightly. At the same time, the pressure plate 1 203 and pressure plate 204 continue to descend, pressing one side of the filter screen 208 against the surface of the base 1 and pressing the other side of the filter screen 208 into the U-shaped plate 209, so that the contact position between the filter screen 208 and the U-shaped plate 209 is inverted U-shaped, thus completing the pressing operation. Subsequently, the cover plate is fixed inside the U-shaped plate 209 to block the pressed filter screen 208, thus completing the pressing and fixing operation of the filter screen 208.

[0064] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
