Technical Field

[0001] The utility model relates to the field of resin production, in particular to an automatic scraper for resin production. Background Art

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external forces, and is solid, semi-solid, or sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for plastic products is called a resin.

[0003] In the prior art, resin unloading operations are required during production.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 3 In an embodiment of the present invention, an automatic scraper for resin production includes a material box 1, a top end of which is provided with a discharge port 2 for discharging resin raw materials, a side of which is provided with a collection box 3 for collecting material residues, and a cleaning mechanism 4 provided on the material box 1;

[0031] The cleaning mechanism 4 includes a reset unit and a cleaning unit;

[0032] The cleaning unit is used to clean the residual slag;

[0033] The reset unit is used to provide a reset elastic force for the movement of the movable plate 405;

[0034] The cleaning unit includes a driving motor 401, a rack 402, a scraper 403, a filter 404, a movable plate 405, and a force-bearing rod 406;

[0035] The drive motor 401 is mounted on the outer wall of one side of the material box 1 through a mounting bracket. The drive motor 401 is used to drive the rack 402 for transmission;

[0036] The rack 402 is rotatably sleeved on the inner wall of the material box 1 and extends to the outside of the material box 1. The rack 402 is used to drive the scraper 403 to move synchronously;

[0037] The scraper 403 is fixed to the outer wall of the rack 402 and is located inside the material box 1. The scraper 403 is used to clean the material residue on the upper surface of the filter screen 404;

[0038] The filter screen 404 is installed in an inclined and sliding manner inside the material box 1, and the filter screen 404 is used to filter the resin raw material;

[0039] The movable plate 405 is axially slidably mounted on the inner wall of the material box 1 and extends from the outside of the material box 1 to the inside of the collection box 3. The movable plate 405 is used to block the residue on the filter screen 404.

[0040] The force rod 406 is fixed to the outer wall of the movable plate 405 and is used to receive the thrust from the scraper 403;

[0041] The reset unit includes a positioning rod 407 and a spring 408;

[0042] The positioning rod 407 is fixed to the inner wall of the material box 1 and passes through the movable plate 405 to the inside of the collection box 3. The positioning rod 407 is used to provide a guide for the axial movement of the movable plate 405;

[0043] Two ends of the spring 408 are respectively clamped on the outer wall of the movable plate 405 and the outer wall of the positioning rod 407. The spring 408 is used to provide a restoring elastic force for the movable plate 405 after movement.

[0044] In this embodiment: when using this device, the material to be filtered is poured into the material box 1 through the discharge port 2, so that the material contacts the filter screen 404, and the material is filtered through the filter screen 404. After filtration, there is material residue on the upper surface of the filter screen 404. By starting the drive motor 401, the drive motor 401 will drive the rack 402 connected to the output end to rotate, and the rotating rack 402 will drive the scraper 403 fixed on the outer wall to move circumferentially, so that the bottom of the scraper 403 contacts the upper surface of the filter screen 404 to clean the material residue on the upper surface of the filter screen 404. At this time, the moving direction of the scraper 403 is the same as the insertion direction of the filter screen 404, and the scraper 403 is used to remove the material residue on the filter screen 404. The slag is pushed to the bottom of the inclined end of the filter 404 and contacts the outer wall of the movable plate 405. The scraper 403 that continues to move contacts the force-bearing rod 406 and gives the force-bearing rod 406 a thrust. The force-bearing rod 406 drives the movable plate 405 to move along the outer wall of the positioning rod 407 and gives the spring 408 an extrusion force, thereby opening the connection port of the material box 1 and the discharge port 2 blocked by the movable plate 405, allowing the slag to enter the collection box 3 through the opened connection port, completing the collection of the slag. Afterwards, the scraper 403 turns upward with the rotation of the rack 402, no longer contacts the upper surface of the filter 404, and returns to its original position, completing the filtering and cleaning of the slag, reducing material waste, and further improving work efficiency.

[0045] Please refer to Figure 1-Figure 3The interior of the material box 1 is formed with a slide groove for the axial movement of the movable plate 405. The movable plate 405 blocks the channel between the material box 1 and the collecting box 3. The interior of the material box 1 is formed with a space for the scraper 403 to move circumferentially. The output end of the drive motor 401 is engaged with the inner side of one end of the rack 402 through the rotating wheel. The outer wall of the filter screen 404 is tilted as a whole. The lowest end of the filter screen 404 is close to the movable plate 405. The interior of the material box 1 is provided with a mounting groove for inserting the filter screen 404.

[0046] In this embodiment: through this structure, when the filter 404 needs to be replaced, the filter 404 can be directly pulled out by applying an upward pulling force to the filter 404, which facilitates the cleaning of the filter 404. The moving trajectory of the scraper 403 ensures that the filter 404 will not be pushed outward when it is inside the material box 1.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
