Description

Technical Field

[0001] This utility model relates to the field of PVC material production and processing technology, specifically to a hot-cutting pelletizing device for PVC material production and processing. Background Technology

[0002] With the rapid development of PVC composite stabilizer processing technology in high-end industries at home and abroad and the increasingly fierce market competition, PVC modified plastics are currently the primary material of choice for many industries. As social productivity changes, there are also considerable requirements for a series of equipment. PVC modified granules are formed by cutting PVC modified granules after production.

[0003] For example, application number CN115245864A discloses a pelletizing device for processing PVC modified materials with high torsion resistance and resilience. This invention includes a main housing, a secondary housing, a groove, a right motor, a right connecting shaft, a rotating shaft, pelletizing blades, a concave plate, and irregularly shaped through holes. A U-shaped groove is fixedly connected to the inner wall of the rear bottom of the main housing, and a load-bearing plate is fixedly connected to the inner wall of the front bottom of the main housing. An elastic column is fixedly connected to the upper surface of the load-bearing plate, and a filter screen is fixedly connected to the outer surface of the end of the elastic column away from the load-bearing plate. The outer surface of the end of the filter screen away from the elastic column is engaged with the inner surface of the U-shaped groove. Through the combination of these structures, the pellets after crushing the PVC modified material can be sorted, so that particles that do not meet production standards can be screened out and re-crushed and pelletized, thereby making the pellet size of the crushed PVC modified material more uniform and improving the crushing and pelletizing effect.

[0004] However, while existing hot cutting pelletizing devices can perform good cutting operations on PVC materials, the screening effect of the cut materials is not high. Furthermore, the recycling of larger materials during screening is not efficient, which reduces the effectiveness of cutting PVC materials.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a hot-cutting pelletizing device for PVC material production and processing. Utility Model Content

A conveying roller that is rotatably connected to the inner wall of the conveying box is fixedly connected to the output end of the conveying drive motor. A circulation port located above the cutting blade is provided on the outer wall of the conveying box.

[0008] Furthermore, a conveying plate located on one side of the guide port is fixedly connected to the side wall of the main body of the device, a guide servo motor is fixedly connected to the outer wall of the guide box, a guide threaded rod that is rotatably connected to the inner side wall of the guide box is fixedly connected to the output end of the guide servo motor, a limiting rod that is slidably connected to the outer wall of the guide threaded rod is threadedly connected to the inner side wall of the guide box, and a limiting groove is formed at the connection between the inner side wall of the guide box and the limiting rod.

[0009] Furthermore, the drive gear is provided in two sets, which are meshed with each other and rotate in opposite directions. The drive gear and the cutting blade are arranged in a one-to-one correspondence.

[0013] Furthermore, the guide threaded rod is provided in two sets, and the two sets of guide threaded rods are arranged in opposite directions of rotation. The limiting rod forms a sliding structure between the guide threaded rod and the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of the conveyor roller, improves the convenience of re-conveying and pelletizing larger materials after sieving and screening when processing PVC materials through the cutting device, and improves the quality of PVC material pelletizing. When larger materials accumulate on the filter screen, the pusher servo motor is turned on, and the pusher screw is rotated to drive the pusher rod to slide along the inner wall of the chute.
