Technical Field

[0001] The utility model relates to the field of polymer material production, in particular to a granulator for polymer materials. Background Art

[0002] Polymer materials, also known as polymer materials, are materials composed of polymer compounds as the matrix and other additives. Polymer materials are divided into rubber, fiber, plastic, polymer adhesives, polymer coatings and polymer-based composite materials according to their characteristics.

[0003] The existing polymer material granulator platens generally granulate by high-speed rotation. The high-speed rotation production efficiency is high, but the produced particles are uneven in size, so the larger particles need to be reworked, which delays labor efficiency.

[0004] Therefore, we need to develop a granulator for polymer materials that can granulate evenly. Utility Model Content

[0005] In order to overcome the disadvantage that the pressing plates of the existing polymer material granulating machines generally granulate by high-speed rotation and the produced particles are uneven in size, the utility model provides a polymer material granulating machine for uniform granulation.

[0006] The technical scheme of the utility model is: a granulator for polymer materials, comprising a support frame, an extrusion barrel, a first motor, a screw, a guide rod, a pressure plate, a mold, a guide plate, a second motor, a scraper and a collecting frame, an extrusion barrel is installed on the top of the support frame, a first motor is installed on the right side of the extrusion barrel, a screw is connected to the output shaft of the first motor, a guide rod is installed on the left side of the extrusion barrel, a pressure plate is slidably provided between the screw and the guide rod, a mold is installed at the bottom of the extrusion barrel, a guide plate is installed in the middle of the support frame, a second motor is installed on the guide plate, a scraper is connected to the output shaft at the top of the second motor, the top of the scraper is fitted with the mold, and a collecting frame is slidably provided in the support frame.

[0007] In one of the embodiments, a fan is further included, and the fan is connected to the output shaft at the bottom of the second motor.

[0008] In one of the embodiments, it also includes a fixing rod, a limiting plate and a torsion spring. The front end of the support frame is equipped with a fixing rod, a limiting plate is rotatably provided on the fixing rod, a torsion spring is sleeved on the fixing rod, and two ends of the torsion spring are respectively connected to the fixing rod and the limiting plate.

[0009] In one of the embodiments, an anti-slip cover is also included, and the front end of the collection frame is provided with an anti-slip cover.

[0010] In one embodiment, the bottom of the press plate is treated with an anti-stick treatment.

[0011] In one embodiment, the guide plate is conical in shape.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model starts the second motor, and the second motor drives the scraper to rotate. When the material is extruded to the mold, the scraper rotates continuously to cut the extruded material into particles. The above actions are repeated, so that the material can be evenly granulated.

[0013] 2. The utility model compresses the torsion spring by rotating the limit plate, and then pulls out the collection frame. After pouring out the materials in the collection frame, the collection frame is put back into the support frame, and then the limit plate is released. Under the action of the torsion spring, the limit plate will be reset, and the collection frame can be stuck, thus achieving the effect of fixing the collection frame.

A fan 12 is connected to the output shaft at the bottom of the second motor 9, and the fan 12 can cool the particles.

[0022] When it is necessary to granulate the polymer material, first place the material into the extrusion barrel 2, then start the first motor 3, the first motor 3 drives the screw 4 to rotate, the rotation of the screw 4 causes the pressing plate 6 to move downward along the guide rod 5, the downward movement of the pressing plate 6 causes the material to be continuously extruded downward, and at the same time start the second motor 9, the second motor 9 drives the scraper 10 to rotate, when the material is extruded to the mold 7, the scraper 10 continuously rotates so that the extruded material is cut into particles, and the continuous operation can evenly cut the material into particles, the cut particles will be guided into the collection frame 11 through the guide plate 8, and the second motor 9 will also drive the fan 12 to rotate when it is turned on, and the rotation of the fan 12 can cool the cut particles.
