[0002] Vibrating screen is a kind of equipment used for material screening and grading. It is commonly used in industries such as plastics, abrasives, chemicals, medicine, building materials, mining, coal, smelting, grain, carbon, and fertilizers. Vibrating screen has the advantages of stability, reliability, low consumption, low noise, long life, stable vibration, high screening efficiency, and convenient maintenance. When using, the vibrating screen mainly uses the internal screen to complete material screening and grading. The screen is woven with metal wire or fiber wire, with an aperture of 0.15~1mm, and can remove and recover different types of small suspended solids. Screen separation has the advantages of simplicity, high efficiency, and low operating cost. The screen needs to be welded to the mesh frame using a rolling welder during production, which can greatly improve the production efficiency and quality of the screen. For example, the existing public document CN221473955U-A screen frame welding device, and the existing public document CN214350523U-A chromatography column barrel filter screen welding device disclose a screen welding device; Although the existing disclosed automatic roll welding machine for mesh frame and screen can realize mesh frame and screen welding, there are still certain shortcomings in actual use: first, the existing automatic roll welding machine for mesh screen fixes the welded mesh frame through multiple groups of pressure blocks when in use, and this method requires controlling multiple groups of cylinders to control and adjust the multiple groups of pressure blocks separately, which will increase the driving power of the equipment, increase the power consumption and cost of the equipment, and the positions of the multiple groups of pressure blocks are fixed and cannot be changed, and cannot be adjusted according to the size of the screen, and the scope of application is small; secondly, the existing automatic roll welding machine for mesh screen requires two pressure rings to be pressed on the surface of the mesh and the mesh frame respectively when in use, and the pressure rings in this method have a certain weight, and the two pressure rings need to be repeatedly taken before and after welding, which will affect the welding efficiency of the mesh and increase the workload of the staff; finally, the existing automatic roll welding machine for mesh screen welds the connection part between the mesh and the mesh frame through the welding wheel when in use, and this method of welding wheel is prone to wrinkles on the surface of the mesh during welding, thereby affecting the welding effect and subsequent use of the mesh; therefore, it is necessary to improve the existing technology to solve the above technical problems.

After the electromagnetic block 205a is energized, it will generate magnetic attraction with the iron block 204a in the lifting frame 204, so that the lifting frame 204 slides downward along the inner wall of the slide frame 205, and drives the first rotating shaft 203 to slide downward with the assistance of the first spline shaft 203a and the first spline sleeve 202.

The output shaft of the motor 201 rotates through the coupling to drive the first spline sleeve 202 to rotate, and the first spline shaft 203a is inserted into the first spline sleeve 202, so when the first spline sleeve 202 rotates, it will drive the first spline shaft 203a and the active bevel wheel 203b to rotate, and when the active bevel wheel 203b rotates, it will drive the first driven bevel wheel 301a to rotate synchronously, and the rotation of the first driven bevel wheel 301a will drive the first threaded rod 301 to rotate, wherein the thread on the outer wall of the first threaded rod 301 is spirally matched with the internal thread in the wall of the threaded hole in the first moving block 302, so when the first threaded rod 301 rotates, it will drive the first moving block 302 to move in the first U-shaped plate 104, thereby changing The positions of the sliding seat 303, the upper pressure plate 307 and the supporting plate 309a are changed to achieve the purpose of adjusting the position of the supporting plate 309a according to the size of the grid body 105 and the screen body 105a, and the application range is wide.

There are two groups of electromagnetic blocks 205a, which can cooperate with the iron block 204a to generate magnetic attraction to adjust the position of the lifting frame 204. The lifting frame 204 is a hollow cross shape. The external thread on the outer wall of the second threaded rod 304 is spirally matched with the internal thread in the wall of the threaded hole on the second moving block 306 to play a transmission role.

It is movably connected to the clamp block 401, and the clamp block 401 is movably installed on the upper surface of the pressure plate 307. The clamp block 401 is pulled downward by the linkage plate 402, so that the clamp block 401 rotates and its end will be pressed on the surface of the screen body 105a on the surface of the frame body 105, thereby realizing the limited clamping of the screen body 105a, thereby reducing the traditional manual operation steps of taking two sets of pressure rings for pressing, reducing the labor intensity of the staff, and at the same time improving the loading and unloading efficiency during the screen welding process.

[0045] Furthermore, the connecting frame 403 is fixed to the outer end of the lifting frame 204, and the surface of the connecting frame 403 is movably connected to the clamping block 401 through a hinge and a linkage plate 402, wherein the clamping block 401 is rotatably installed on the surface of the pressure plate 307, so when the connecting frame 403 moves with the lifting frame 204, it will drive the clamping block 401 to rotate. Example 3

[0046] Reference Fig.11 and Fig.12 , which is the third embodiment of the present invention, is based on embodiment 1, except that, in order to ensure the welding quality of the screen body 105a, the elastic properties of the torsion spring 503 are utilized to move the arc plate 504 outward to push the welding part of the screen body 105a outward, so that the welding part of the screen body 105a is in a stretched state.

[0047] Specifically, it also includes a calendering assembly 500 arranged on one side wall of the slide plate 106d, the calendering assembly 500 includes a second U-shaped plate 501 fixedly arranged on one side wall of the slide plate 106d and a second rotating shaft 502 rotatably mounted on the inner wall of the second U-shaped plate 501, a torsion spring 503 is sleeved on the middle part of the outer wall of the second rotating shaft 502; both sides of the outer wall of the second rotating shaft 502 are fixedly connected to the arc plate 504 through connecting blocks, and the bottom of the arc plate 504 is bonded with rubber pads 504a in an array from front to back; When the above arrangement is used, after the grid body 105 and the screen body 105a are respectively limited, the position of the welding wheel 106f on the vertical frame 106b is adjusted under the action of the translation mechanism 106, and then the electric push rod 106e is used to push the slide plate 106d to rise and fall on the surface of the slide rail 106c, so as to adjust the height of the welding wheel 106f. During the descent of the welding wheel 106f, the bottom of the arc plate 504 located outside thereof will first contact the surface of the screen body 105a, and as the slide plate 106d is maintained, the welding wheel 106f will be moved downward. As the arc plate 504 continues to move downward, it will rotate outward with the second rotating shaft 502 as the center and squeeze the torsion spring 503. During the rotation of the arc plate 504, the rubber pad 504a at the bottom of the arc plate 504 will contact the surface of the screen body 105a, and the screen body 105a at the welding position will be pushed outward as the arc plate 504 rotates, so that the screen body 105a at the welding position is in a stretched state, thereby avoiding the looseness of the screen body 105a after welding and improving the welding quality.

[0048] Furthermore, when the arc plate 504 is subjected to force, it will rotate with the second rotating shaft 502 as the center, and push the screen body 105a at the welding position outward under the action of the rubber pad 504a, wherein the rubber pad 504a is only located at the bottom of the arc plate 504. After the arc plate 504 is tilted, the rubber pad 504a will move outward and will not affect the rotation welding of the frame body 105 and the screen body 105a. Example 4
