Description

Technical Field

[0001] This utility model belongs to the field of screen cutting technology for sorting machines, and in particular relates to an anti-deviation device for cutting sorting screens. Background Technology

[0002] The cutting quality of the screen mesh in a sorting machine directly affects the screening efficiency and equipment lifespan, requiring strict control over three aspects: dimensional accuracy, tension, and installation details. During cutting, the screen width should match the frame, and the length should extend 50-70mm beyond the frame to ensure the edges reach the discharge port and prevent material mixing. For equipment such as linear vibrating screens, special attention must be paid to the flatness of the screen mesh after cutting. Screen mesh cutting is performed by pulling out the rolled screen material, a process that requires the use of a cutting device.

[0003] After the screen is pulled out, it is guided to the conveying roller by the guide roller, and then cut by the cutting component to obtain the required screen length. During this process, the screen may deviate due to the transmission of vibration, which affects its cutting flatness. Therefore, an anti-deviation device for cutting sorting screens is needed to apply force to the pulled-out screen in the center to prevent it from deviating during transmission, thereby making its position more accurate and improving its cutting precision. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deviation device for cutting sorting screens, which applies force to the pulled-out screen in a centered manner to prevent it from shifting during transmission, thereby making its position more accurate and improving its cutting precision, thus solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for preventing deviation in the cutting of sorting screens, comprising a frame plate: two symmetrically arranged sliding plates are slidably connected to the surface of the frame plate; a cylinder is fixedly connected to the surface of the frame plate by bolts; the output end of the cylinder is fixedly connected to the sliding plate located on the left side; a rotating plate is rotatably connected to the surface of the frame plate by a rotating shaft; a connecting rod is rotatably connected between the rotating plate and the sliding plate; a U-shaped block is fixedly connected to the surface of the sliding plate; a cutting table is fixedly installed on the surface of the frame plate; a side plate is fixedly installed on the top of the cutting table; a guide roller is rotatably connected to the surface of the side plate; and a conveying roller assembly and a cutting blade assembly are installed on the top of the cutting table.

[0006] Preferably, the surface of the skateboard is integrally formed with a slider, and the surface of the frame plate is provided with a groove adapted to the slider.

This utility model uses the rotation of the rotating plate to drive the connecting rod to deflect, so that the connecting rod drives the U-shaped block through the sliding plate to apply force to the edge of the screen in the center, thereby achieving the purpose of applying force to the screen pulled out in the center, avoiding deviation during transmission, and making its position more accurate, thereby improving its cutting accuracy. 2. This utility model uses the combination of slider and groove to limit the sliding of the skateboard on the frame surface, thereby preventing the skateboard from shaking during movement and improving the stability of the skateboard when moving. 3. This utility model isolates the U-shaped block and the screen by setting up a rotating wheel, avoiding the situation of squeezing and damage when the two are in direct contact, and also avoiding the situation of the screen being greatly obstructed during transmission. 4.

[0013] In the following description, embodiments of the anti-deviation device for cutting sorting screens according to the present invention will be described with reference to the accompanying drawings.

[0014] Example 1: Figure 1-3This invention illustrates an embodiment of an anti-deviation device for cutting sorting screens, comprising a frame plate 1. Two symmetrically arranged sliding plates 2 are slidably connected to the surface of the frame plate 1. A cylinder 3 is bolted to the surface of the frame plate 1, and the output end of the cylinder 3 is fixedly connected to the sliding plate 2 on the left side. A rotating plate 4 is rotatably connected to the surface of the frame plate 1 via a rotating shaft. A connecting rod 5 rotatably connects the rotating plate 4 and the sliding plate 2. A slider 6 is integrally formed on the surface of the sliding plate 2. A groove 7 adapted to the slider 6 is formed on the surface of the frame plate 1. Through the cooperation of the slider 6 and the groove 7, the sliding of the sliding plate 2 on the surface of the frame plate 1 is limited, preventing the sliding plate from deflecting. 2. Shaking occurs during movement, thereby improving the stability of the slide plate 2 during movement. A U-shaped block 8 is fixedly connected to the surface of the slide plate 2, and a rotating wheel 9 is rotatably connected to the inner wall of the U-shaped block 8. The rotating wheel 9 isolates the U-shaped block 8 from the screen, avoiding squeezing damage when the two are in direct contact, and also avoiding excessive resistance during the transmission of the screen. A cutting table 11 is fixedly installed on the surface of the frame plate 1, and a side plate 12 is fixedly installed on the top of the cutting table 11. A guide roller 13 is rotatably connected to the surface of the side plate 12, and a conveying roller group 14 and a cutting blade group 15 are installed on the top of the cutting table 11.

[0015] Example 2: Figure 1-3 This invention illustrates an embodiment of an anti-deviation device for cutting a sorting screen, comprising a frame plate 1; two symmetrically arranged sliding plates 2 are slidably connected to the surface of the frame plate 1; a cylinder 3 is fixedly connected to the surface of the frame plate 1 by bolts; the output end of the cylinder 3 is fixedly connected to the sliding plate 2 located on the left; a rotating plate 4 is rotatably connected to the surface of the frame plate 1 via a rotating shaft; a connecting rod 5 is rotatably connected to the rotating plate 4 and the sliding plate 2; a U-shaped block 8 is fixedly connected to the surface of the sliding plate 2; and a cutting table 11 is fixedly mounted on the surface of the frame plate 1. A side plate 12 is fixedly installed, and a guide roller 13 is rotatably connected to the surface of the side plate 12. A conveying roller assembly 14 and a cutting blade assembly 15 are installed on the top of the cutting table 11. A screen roll is installed on the surface of the side plate 12. One side of the screen roll is wrapped around the surface of the guide roller 13 and passes through the conveying roller assembly 14. A rubber sleeve 10 is pasted on the surface of the rotating wheel 9. The rubber sleeve 10 isolates and protects the rotating wheel 9 from the screen when they come into contact, thus preventing the rotating wheel 9 from being scratched by the screen during transmission and improving the service life of the rotating wheel 9.

[0016] Working principle: When using this utility model, the user installs the screen roll on the surface of the side plate 12, then pulls out one side of the screen and passes it around the guide roller 13 and through the conveyor roller group 14. Then, the screen is cut by the conveying action of the conveyor roller group 14 and the cooperation of the cutting blade group 15. The cylinder 3 drives the left slide plate 2 to move, so that the rotation of the rotating plate 4 causes the connecting rod 5 to deflect. Then, the connecting rod 5 drives the U-shaped block 8 through the slide plate 2 to apply force to the edge of the screen in a centered manner, so as to achieve centered force on the pulled-out screen, avoid its deviation during transmission, and make its position more accurate, thereby improving its cutting accuracy.

[0017] In summary, this anti-deviation device for cutting sorting screens uses the rotation of the rotating plate 4 to drive the connecting rod 5 to deflect. This causes the connecting rod 5 to drive the U-shaped block 8 through the sliding plate 2 to apply force to the edge of the screen in a centered manner. This achieves the purpose of applying force to the screen pulled out in a centered manner, preventing it from deviating during transmission, and thus making its position more accurate, thereby improving its cutting precision.
