[0020] Preferably, the driving assembly 2 includes a driving source 21 arranged on the vibrating screen conveyor belt 1, the driving source 21 is slidably connected to the vibrating screen conveyor belt 1, a first bevel gear 22 is arranged on the output end of the driving source 21, a first gear member 23 is sleeved on the output end of the driving source 21, the first gear member 23 is meshed with a first rack member 24, the first rack 24 is arranged on the vibrating screen conveyor belt 1, and the cooperation between the first gear member 23 and the first rack 24 enables the driving source 21 to move along the length direction of the rack during output.

[0021] Preferably, the cleaning component includes a first sliding member 31 arranged in a sliding connection with the first rack 24, and the cleaning component also includes a second sliding member 32 slidably connected to the vibrating screen conveyor belt 1. The first sliding member 31 and the second sliding member 32 are both rotatably connected to a rotating shaft 33. A second bevel gear 34 is arranged at one end of the rotating shaft 33, and the second bevel gear 34 meshes with the first bevel gear 22.

The second gear member 35 meshes with a second rack 36. The second rack 36 is arranged on the vibrating screen conveyor belt 1. The first sliding member 31 is rotatably connected to the output end of the driving source 21. Through the arrangement of the second rack 36, the rotating shaft 33 can drive the first sliding member 31 and the second sliding member 32 to move synchronously when moving, and through the meshing of the first bevel gear 22 and the second bevel gear 34, the rotating shaft 33 can rotate while moving.

[0022] Preferably, a first spring expansion member 37 is arranged above the first sliding member 31, and a second spring expansion member 38 is arranged above the second sliding member 32.

The output ends of the first spring expansion member 37 and the second spring expansion member 38 are fixedly connected to the two ends of a first scraper 310. The two limiting members 39 are limited by the guide rails so that the first scraper 310 does not contact the vibrating screen conveyor belt 1 when cleaning is not performed, thereby preventing the first scraper 310 from affecting the screening of resin by the vibrating screen conveyor belt 1. At the same time, through the movement of the first sliding member 31 and the second sliding member 32, the first scraper 310 is gradually moved downward to clean the top of the vibrating screen conveyor belt 1 when cleaning is performed.

[0023] Preferably, the cleaning assembly 3 also includes two rotating members 311, both of which are rotatably connected to the rotating shaft 33, one rotating member 311 is fixedly connected to the first sliding member 31, and the other rotating member 311 is fixedly connected to the second sliding member 32, and both of the rotating members 311 are fixedly connected to a second scraper 312, and a brush 313 is sleeved on the rotating shaft 33. Through the rotation and movement of the rotating shaft 33, the brush 313 moves while rotating, so that the resin in the sieve holes on the vibrating screen conveyor belt 1 is cleaned and falls, and the movement of the first sliding member 31 and the second sliding member 32 causes the second scraper 312 to move, driving the cleaned resin on the limit plate to slide into the first slide rail 11.

[0024] Preferably, a limit plate is provided on the vibrating screen conveyor belt 1, and one end of the limit plate is connected to a first slide rail 11. Under the setting of the first slide rail 11, the resin slides into the storage box 45 and is collected.

The extension plate 46 is fitted with a support plate 47, and the support plate 47 is fixedly set on the factory floor. The support plate 47 is fixedly connected to one end of a second track 48, and the second track 48 is fixedly set on the factory floor through a fixing seat 49. The other end of the second track 48 is located above the vibrating screen conveyor belt 1. The setting of the extension plate 46 ensures that the storage box 45 will not be separated from the second track 48 when tilted, thereby preventing the resin from spilling outside the second track 48.

[0027] Preferably, the secondary screening component 4 also includes a fixing member 410 arranged on the vibrating screen conveyor belt 1, and a push plate 411 is slidably connected to the fixing member 410, and the push plate 411 corresponds to the position of the driving source 21. The push plate 411 is fixedly connected to one end of a connecting rope 412, and the other end of the connecting rope 412 is fixedly connected to the top of the sliding rod 43. Through the setting of the first push plate 411, the storage box 45 can fall to the discharge port of the first slide rail 11 before the resin is pushed into the first slide rail 11 on the limiting plate, and can drive the storage box 45 to move up to the second slide rail when the driving source 21 is reset, and under the setting of the first slide rail 11, the resin is sent to the vibrating screen conveyor belt 1 for screening again, so as to ensure that most of the qualified granular resin can be collected and bagged, and prevent more qualified granular resin from being cleaned.

[0028] Working principle: Since the resin is cut into granules, part of the resin blocks the filter holes on the vibrating screen conveyor belt 1 after screening. By starting the driving source 21 to drive the first bevel gear 22 to rotate, the rotating shaft 33 rotates, so that the brush 313 starts to rotate, and drives the second gear member 35 to rotate. At the same time, since the driving source 21 drives the first gear member 23 to rotate when it rotates, and the first rack 24 and the second rack 36 are set, the driving source 21 starts to move when it rotates, and the driving source 21 drives the first sliding member 31 to move when it moves. When the second gear member 35 rotates, it drives the second sliding member 32 to move, so that the rotating shaft 33 starts to move. With the cooperation of the rotation of the brush 313, the brush 313 moves when it rotates, so that the brush 313 cleans the granular resin remaining in the sieve holes on the vibrating screen conveyor belt 1, so that the resin falls on the limit plate; When the rotating shaft 33 moves, the second scraper 312 is driven to move, so that the second scraper 312 pushes the resin cleaned on the limiting plate, so that the resin is pushed into the first slide rail 11, and then slides into the storage box 45 from the first slide rail 11; When the first sliding member 31 and the second sliding member 32 move, they drive the first spring telescopic rod and the second spring telescopic rod to move, so that the two limit members 39 move along the guide track direction, so that the first spring member and the second spring member contract, and drive the first scraper 310 to move downward, so that the first scraper 310 cleans the upper surface of the vibrating screen conveyor belt 1, so that the resin bounced to the top of the vibrating screen conveyor belt 1 by the brush 313 during cleaning is pushed and screened, and qualified resin products are collected after screening, and resin that fails to pass the screening will fall on the limit plate and be pushed into the storage box 45 by the second push plate 411; When the driving source 21 moves toward the first slide rail 11 during cleaning, due to the gravity of the storage box 45, the driving source 21 moves, and the push plate 411 moves one end distance synchronously, so that the connecting rope 412 moves, driving the sliding rod 43 to move downward, so that the limit shaft 44 moves downward, and the storage box 45 falls to the discharge port of the first slide rail 11. When the driving source 21 completes cleaning and resets, when the driving source 21 moves to contact with the push plate 411, it drives the push plate 411 to move. The connecting rope 412 is pulled, driving the sliding rod 43 to move upward, causing the limit shaft 44 to move upward and driving the storage box 45 to move upward. When the storage box 45 moves up to the point where its extension plate 46 is higher than the second slide rail, the storage box 45 is tilted due to its weight, so that the resin collected in the storage box 45 can slide again onto the vibrating screen conveyor belt 1 through the second slide rail for screening, so as to ensure that most of the qualified granular resin can be collected and bagged, and prevent more qualified granular resin from being cleaned up.

[0029] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
