Description

Technical Field

[0001] The utility model relates to the field of strip plastics, in particular to a strip plastic pelletizer. Background Art

[0002] Plastic strips are strip products made of plastic, which usually have strong flexibility and durability. In the steel industry, plastic strips are widely used in various fields, such as packaging, transportation, protection, etc. They can help steel companies improve production efficiency, reduce costs, ensure product quality, and contribute to environmental protection. If strip plastics are pelletized during the production process, a pelletizer is required. A pelletizer is a mechanical material processing equipment that can cut various materials into granules or small blocks. The working principle of the pelletizer is to use a high-speed rotating tool or cutting wheel to cut the material. The particle size can be adjusted by controlling different parameters such as speed, pressure, and cutting angle.

[0003] After searching, a plastic pelletizer with a publication number of CN213766631U is disclosed, which specifically discloses a plastic pelletizer, including a pelletizer body, a driven pressure roller is rotatably connected to the inner wall of the pelletizer body, a driving gear knife is rotatably connected to the inner wall of the pelletizer body near the driven pressure roller, the height of the driving gear knife is higher than the driven pressure roller, a connected cooling air duct is fixed above the pelletizer body, the cooling air duct is downward toward between the driven pressure roller and the driving gear knife, a cleaning brush is fixed on the inner wall of the pelletizer body, and the cleaning brush is in contact with the driving gear knife. A feed port is provided on the other side of the pelletizer body, and a discharge port is provided at the bottom of the pelletizer body. The new plastic pelletizer of the utility model is composed of a cooling air duct, a feed port, a driving gear knife, a driven pressure roller, a baffle, and a cleaning brush. The cooling air in the cooling air duct can effectively cool the plastic particles, the driving gear knife, and the driven pressure roller, and is conducive to cleaning the plastic particles remaining on the blade, and the brush can more effectively clean the plastic particles adhering to the driving gear knife in time, thereby improving the pelletizing effect and ensuring that the shape of the plastic particles is uniform.

[0004] In the above patent, the plastic particles, the active gear knife, and the driven pressure roller are effectively cooled only by the cooling air duct, the feed port, the active gear knife, the driven pressure roller, the baffle plate and the cleaning brush, and the residual plastic particles on the blade can be cleaned up more effectively. The plastic particles adhering to the active gear knife can be cleaned up in time by the brush, so as to improve the pelletizing effect and ensure the uniform shape of the plastic particles. However, before pelletizing the strip plastic, the plastic pelletizer needs to manually feed the strip plastic into the pelletizing port. Such feeding method not only wastes time, but also has certain feeding risks, and cannot fully complete the pelletizing work of the strip plastic. At the same time, strip plastics of different thicknesses require different roller spacings for pelletizing. If the thickness of the strip plastic is greater than the roller spacing, it is not only inconvenient to perform the pelletizing work normally, but also requires frequent replacement of the matching pelletizer.

[0005] Therefore, it is necessary to invent a strip plastic pelletizer to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a strip plastic pelletizer, which can adjust the spacing between the first spacing roller and the second spacing roller according to the thickness of the strip plastic through a machine cover, a fixed card slot, a fixed card block, a feeding rack, a small electric conveyor belt, a telescopic sleeve, a fixed knob and an extension plate, so that the device can meet the pelletizing work of strip plastics with different thicknesses, thus avoiding the safety hazards caused by manual feeding, speeding up the working time of the device for pelletizing, and expanding the overall pelletizing range, avoiding the need to frequently replace the matching pelletizer in the face of strip plastics with different thicknesses, so as to solve the problem that the plastic pelletizer in the prior art needs to manually feed the strip plastic into the pelletizing port before pelletizing the strip plastic, and such a feeding method not only wastes time, but also has certain feeding hazards, and cannot fully complete the pelletizing work of the strip plastic. At the same time, strip plastics of different thicknesses require different roller spacings when pelletizing. If the thickness of the strip plastic is greater than the roller spacing, it is not only inconvenient to perform the pelletizing work normally, but also requires frequent replacement of the matching pelletizer.

[0012] Preferably, a sliding groove is provided inside the collecting trough plate, a sliding block is movably connected inside the sliding groove, and a collection box is fixedly installed at one end of the sliding block.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. Through the setting of the machine cover, fixed card slot, fixed card block, feeding rack, small electric conveyor belt, telescopic sleeve, fixed knob and extension plate, when the device is used to pelletize strip plastic, the height of the telescopic sleeve and the extension plate can be adjusted by the fixed knob according to the current thickness and length requirements of the strip plastic before pelletizing.
