Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pelletizers, in particular to a pelletizer for modified plastic production. Background Art
[0002] Modified plastics refer to plastic products that are processed and modified by methods such as filling, blending, and reinforcement on the basis of general-purpose plastics and engineering plastics, and have improved performance in aspects such as flame retardancy, strength, impact resistance, and toughness.
[0003] In the actual use process of the existing pelletizer, when cutting plastic strips, the high-temperature plastic is prone to sticking to the cutting blade. According to the patent with the Chinese utility model publication number CN216941398U, which discloses a pelletizer for modified plastic production, the utility model is provided with a cold air blower, an air inlet pipe, a fixed pipe, a nozzle, and a connecting plate. When the cold air blower operates, it will extract external air through the air inlet pipe, and then convert it into cold air and spray it out from the nozzle through the exhaust pipe and the fixed pipe in sequence, so as to cool the high-temperature plastic strips, which can reduce the adhesiveness of the plastic, making it difficult for plastic particles to stick to the outer surface of the blade body when the blade body cuts the plastic strips. Due to the design of the connecting plate, when plastic particles stick to the outer surface of the blade body, the plastic particles will be scraped off by the movement of the blade body.
[0004] In the actual use process of the existing pelletizer, when cutting plastic strips, the high-temperature plastic is prone to sticking to the cutting blade. As described in the above patent, although it solves this problem, in the actual use process, due to the lack of a collection device, the scraped debris contacts the plastic particles, thus affecting the production quality and lacking certain practicality.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment 1
[0030] Refer to Figure 1-6 , a pelletizer for modified plastic production, comprising a main body assembly 1; the main body assembly 1 includes a box body 11, inside which a storage box 12 is slidably connected; a fixing plate 13, fixedly connected to the inner side wall of the box body 11; a cutting knife 14, arranged inside the box body 11; a scraping plate 15, fixedly connected to the inner side wall of the box body 11 and symmetrically arranged in two; a collecting assembly 2 is arranged on the box body 11, and the collecting assembly 2 includes: an installation box 21, fixedly connected to the outer side wall of the box body 11; a motor 22, fixedly connected to the top of the installation box 21, and the output end thereof is inserted into the installation box 21; a reciprocating threaded rod 23, fixedly connected to the output end of the motor 22; a connecting block 24, threadedly connected to the outer side wall of the reciprocating threaded rod 23; a connecting plate 25, fixedly connected to the front surface of the connecting block 24, and the cutting knife 14 is fixedly connected to the connecting plate 25; a driving mechanism 26, arranged on the installation box 21; a collecting shell 27, arranged inside the box body 11; the driving mechanism 26 includes: a reciprocating threaded rod 261, rotatably connected to the inside of the installation box 21; a bevel gear 262, the reciprocating threaded rod 261 and one end of the driving mechanism 26 are both fixedly connected with a bevel gear 262, and the two bevel gears 262 are engaged with each other; a connecting block 263, threadedly connected to the outer side wall of the reciprocating threaded rod 261; a connecting plate 264, fixedly connected to the front surface of the connecting block 263 and fixedly connected to the collecting shell 27; a limiting block 4 is fixedly connected to the outer side wall of the reciprocating threaded rod 23.
[0031] When ready for use, place the box body 11 at the designated position. Then, convey the strip-shaped plastic into the box body 11 through the conveying device and slide it to the right on the fixing plate 13. Subsequently, the operator connects the power supply of the motor 22 and turns on the motor 22. The motor 22 drives the reciprocating threaded rod one 23 to rotate in the installation box 21. The rotation of the reciprocating threaded rod one 23 drives the connecting block one 24 to move up and down reciprocally, so that the connecting block one 24 drives the cutting knife 14 to move up and down simultaneously through the connecting plate one 25 to cut the strip-shaped plastic. The cut plastic falls into the storage box 12 for collection. While the cutting knife 14 moves up and down reciprocally, the scraper 15 scrapes the debris adhered to its surface. While scraping, the driving mechanism 26 drives the collection shell 27 to move, so that when the cutting knife 14 moves upward for the scraping process, the collection shell 27 just moves to the lower part of the cutting knife 14 to collect the scraped debris, thus preventing the debris from falling and contacting and adhering to the surface of the strip-shaped plastic, thereby improving the production stability of the device; the rotation of the reciprocating threaded rod one 23 drives the bevel gear 262 on it to rotate simultaneously. Through the meshing connection, the two bevel gears 262 move simultaneously, thereby driving the reciprocating threaded rod two 261 to rotate, so that the reciprocating threaded rod two 261 drives the connecting block two 263 to move left and right reciprocally, and the connecting block two 263 drives the collection shell 27 to move left and right reciprocally through the connecting plate two 264, so that the collection shell 27 moves to the lower part of the cutting knife 14 to collect the debris; a limiting block 4 is fixedly connected to the outer side wall of the reciprocating threaded rod one 23. The limiting block 4 can limit the moving range of the connecting block one 24 and prevent the connecting block one 24 from contacting the bevel gear 262 when moving, thereby avoiding collision, and thus improving the safety of the device.
[0032] Embodiment 2
[0033] Refer to Figure 1-6 , on the basis of Embodiment 1, the function of auxiliary collection is added;
[0034] An auxiliary collection assembly 3 is provided on the box body 11. The auxiliary collection assembly 3 includes: mounting plates 31, fixedly connected to the bottom of the collection shell 27 and symmetrically arranged in two; baffles 32, slidably connected to the opposite surfaces of the two mounting plates 31; springs 33, each spring 33 is arranged inside each mounting plate 31, and both ends of each spring 33 are respectively fixedly connected to the outer side wall of the baffle 32 and the inside of the mounting plate 31; collection pipes 34, inserted into the box body 11 and fixedly connected to the box body 11; a telescopic rod 5 is fixedly connected to the inside of each mounting plate 31, and both ends of each telescopic rod 5 are respectively fixedly connected to the outer side wall of the baffle 32 and the inside of the mounting plate 31; the inner bottom surface of the collection shell 27 is an inclined surface.
[0035] During use, when the collection shell 27 moves to the right after the collection is completed, the collection pipe 34 presses against the baffle 32, causing the baffle 32 to slide to the left and pull the spring 33, so that the debris collected inside the collection shell 27 falls into the collection pipe 34. The operator can collect it outside the device. When the collection shell 27 moves to the left, under the action of the spring 33, the baffle 32 is pulled back to block the bottom of the collection shell 27 to prevent debris from falling, so that the operator can collect the debris without opening the device, thus improving the convenience of the device; Each mounting plate 31 is fixedly connected with a telescopic rod 5 inside. When the baffle 32 moves, it drives the telescopic rod 5 to expand and contract at the same time. The telescopic rod 5 can limit the moving direction of the baffle 32 to prevent the baffle 32 from being skewed by the elastic force and getting stuck inside the device, thus improving the stability of the device; The inner bottom surface of the collection shell 27 is inclined, so that the debris can fall out of the collection shell 27 along the inclined surface, preventing the debris from remaining inside the collection shell 27 and requiring the operator to manually clean it, thus improving the working efficiency of the operator.
[0036] 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
