[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1: This example 1 provides a papermaking environmentally friendly filter mesh weaving edge locking device, which is directly improved on the existing polyester forming mesh production glue edge machine, and has a unique structure.

[0029] There are various ways to drive-connect the second motor 19 with the sleeve 25. For example: the lower end of the sleeve 25 extends out of the fixing plate 3 and is fixedly connected to the output shaft of the second motor 19 through a coupling. The stirring assembly includes connecting cylinders 24 symmetrically and fixedly installed on both sides of the sleeve 25. The adjacent ends of the two connecting cylinders 24 are both communicated with the inside of the sleeve 25. The other ends of the two connecting cylinders 24 are both sealed and fixedly installed with U-shaped frames 30. The other ends of the U-shaped frames 30 are fixedly installed with scraping plates 32. The scraping plates 32 are in contact with the inner side wall of the glue storage tank 2, so as to scrape off the glue liquid on the inner wall of the glue storage tank 2. A connecting shaft 29 is rotatably installed in the U-shaped frame 30. Stirring rods 31 are fixedly installed on the connecting shaft 29 at equal intervals along the axial direction. A plurality of transmission components are arranged in the sleeve 25. One ends of the two connecting shafts 29 on the same horizontal line both extend into the connecting cylinder 24 and are drivingly connected with the sleeve 25 through the adjacent transmission components. The transmission components include a first bevel gear 27 and second bevel gears 28. The first bevel gear 27 is fixedly sleeved on the rotating shaft 26. There are two second bevel gears 28. The two second bevel gears 28 are respectively fixedly sleeved on the two connecting shafts 29, and both of the two second bevel gears 28 are in meshing transmission with the first bevel gear 27.

[0030] The driving mechanism includes a driving motor 5, and also includes fixing plates 3 symmetrically and fixedly installed on the front and rear sides of the frame 1. An extrusion roller 6 and a driving roller 4 are rotatably installed between the two fixing plates 3 at intervals in the vertical direction. The driving roller 4 is located above the extrusion roller 6 and is drivingly connected with the driving motor 5. There are various ways to drive-connect the extrusion roller 6 with the driving motor 5. For example: the driving motor 5 is fixedly installed on one of the fixing plates 3. The driving shaft of the extrusion roller 6 penetrates through the fixing plate 3 and is fixedly connected to the output shaft of the driving motor 5. Sliders 7 are slidably installed on both of the fixing plates 3 in the vertical direction. Push-top components are arranged at the bottoms of the two sliders 7. The two ends of the extrusion roller 6 are respectively rotatably installed on the two sliders 7. In the initial state, the push-top components push the extrusion roller 6 into contact with the driving roller 4. There are various ways to install the sliders 7. For example: a chute is vertically opened at the lower part of the fixing plate 3. The slider 7 is slidably installed in the chute. Through grooves penetrating the fixing plate 3 are opened on both the left and right sides of the chute. The push-top component includes a connecting rod 9 fixedly installed in the through groove in the vertical direction. A sliding cylinder 8 is slidably sleeved on the connecting rod 9. Both of the two sliding cylinders 8 are fixedly connected to the slider 7. A spring 10 is movably sleeved on the connecting rod 9 below the sliding cylinder 8.

[0031] The edge-locking mechanism includes connecting plates 11 symmetrically and fixedly installed on the front and rear sides of the frame 1. U-shaped plates 17 are fixedly installed on the left and right sides of the two connecting plates 11, and cavities are formed inside the two U-shaped plates 17 away from the driving mechanism. A bidirectional telescoping mechanism is provided on the frame 1. The bidirectional telescoping mechanism includes a first motor 12, a transmission belt 15, and a lead screw 13 rotatably installed longitudinally on the frame 1. The two connecting plates 11 are slidably installed longitudinally on the frame 1 and are threadedly connected to the lead screw 13. A second pulley 16 is fixedly sleeved on the output shaft of the first motor 12, and a first pulley 14 is fixedly sleeved on the lead screw 13. The first pulley 14 and the second pulley 16 are connected by the transmission belt 15. The cavity of the U-shaped plate 17 is communicated with the output end of the water pump 23. The distance between the upper and lower support plates of the U-shaped plate 17 is the same as the thickness of the filter screen, and glue discharge holes communicating with the cavity are formed on the adjacent surfaces of the upper and lower support plates of the U-shaped plate 17. An air-drying device is provided between the two U-shaped plates 17 on the same connecting plate 11. The output end of the water pump 23 is communicated with a second connecting pipe 21. The other end of the second connecting pipe 21 is connected to a third connecting pipe 22 through a three-way pipe, and the other end of the third connecting pipe 22 is respectively communicated with the adjacent side cavities. By making the distance between the upper and lower support plates of the U-shaped plate 17 the same as the thickness of the filter screen, the U-shaped plate 17 can scrape the glue liquid flat while applying glue to the filter screen. The air-drying device includes two exhaust fans. Support plates are fixedly installed on the upper and lower parts within the enclosed area of the two U-shaped plates 17, and the two exhaust fans are respectively fixedly installed on the adjacent surfaces of the two support plates.

[0032] When the staff uses this edge-locking device to lock the edge of the filter screen, first inject the glue liquid into the glue storage tank 2, and then start the electric heating tube 33 and the second motor 19. The electric heating tube 33 heats the glue liquid to prevent it from solidifying. The second motor 19 drives the sleeve 25 to rotate. After the sleeve 25 rotates, it drives the connecting cylinder 24 and the U-shaped frame 30 to rotate. On the one hand, it stirs the glue liquid in the horizontal direction, and on the other hand, it can scrape the glue liquid on the inner wall of the glue storage tank 2 to prevent the glue liquid from solidifying on the inner wall of the glue storage tank 2 during the heating process. At the same time, when the sleeve 25 rotates, relative rotation occurs between the sleeve 25 and the rotating shaft 26, so that the second bevel gear 28 meshes and drives circumferentially along the first bevel gear 27, and then drives the connecting shaft 29 to rotate, thereby stirring the glue liquid vertically. Then start the first motor 12. The first motor 12 drives the lead screw 13 to rotate through belt transmission. After the lead screw 13 rotates, the two connecting plates 11 move away from or close to each other through threaded connection, so as to adjust the distance between the two connecting plates 11 according to the width of the filter screen, and put one end of the filter screen through the U-shaped plate 17 and place it between the driving roller 4 and the pressing roller 6.

[0033] Then, the drive motor 5 and the water pump 23 are started simultaneously. The drive motor 5 drives the drive roller 4 to rotate, thereby driving the filter screen to continuously move to the left. During the movement of the filter screen, the water pump 23 pumps out the glue liquid in the glue storage tank 2 and discharges it through the glue discharge holes on the upper and lower support plates of the U-shaped plate 17. Thus, the upper and lower surfaces on both the front and back sides of the filter screen can be coated with glue simultaneously, and the filter screen is edge-locked with the glue liquid. Moreover, since the distance between the upper and lower support plates of the U-shaped plate 17 is adapted to the thickness of the filter screen, when edge-locking, the upper and lower surfaces of the filter screen will respectively contact the two support plates, so that the glue liquid can be leveled while edge-locking. Then, the filter screen coated with glue will move to the air-drying device, and the glue liquid is dried by the wind blown by the exhaust fan, thus preventing the glue liquid from sticking to the drive roller 4 and the pressing roller 6. Through the combined setting of the stirring mechanism and the edge-locking mechanism, not only can the glue liquid in the glue storage tank 2 be stirred in the horizontal and vertical directions to prevent the glue liquid from settling, but also the upper and lower surfaces on both the front and back sides of the filter screen can be edge-locked simultaneously, improving the edge-locking efficiency.

[0034] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is as Figure 1 shown. A placement plate 18 is fixedly installed on the top of the frame 1, and the upper surface of the placement plate 18 is flush with the upper surface of the lower support plate of the U-shaped plate 17, making the transmission of the filter screen more stable.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
