Description

Technical Field

[0001] This utility model relates to the technical field of raw material mixing mechanisms, specifically a raw material mixing mechanism for processing plastic products. Background Technology

[0002] Raw material mixing for plastic products typically occurs after the initial processing of plastic granules or powders. At this stage, various plastic raw materials (such as synthetic resins and additives) weighed according to the formulation are placed into a mixing device and thoroughly mixed using methods such as stirring. The purpose of this step is to ensure that the various raw materials are fully mixed so as to obtain a homogeneous plastic material in subsequent processing.

[0003] While existing technologies can achieve the effect of mixing raw materials, current mixing equipment typically cannot achieve segmented feeding during the mixing process. When a large number of raw materials need to be added, uneven distribution of pigments or additives can occur, potentially leading to uneven surface color or performance differences in the product. Furthermore, the equipment cannot dry the raw materials after mixing. If the mixed raw materials contain moisture, it can cause air pockets to form inside the plastic product during subsequent molding. Therefore, a raw material mixing mechanism for plastic product processing is proposed to solve the above problems. Utility Model Content

[0024] As a preferred technical solution in this embodiment: In actual use, the operator can put different raw materials into the feeding cylinder 33, and then control the feeding cylinder 33 to add various raw materials into the mixing chamber 32 according to the usage requirements. Then, the operator can control the rotary motor 15 to drive the transmission gear 16 to rotate. During the rotation of the transmission gear 16, the driven gear 21 can be driven to rotate. During the rotation of the driven gear 21, the connecting platform 22 and the mounting platform 23 can be driven to rotate. During the rotation of the mounting platform 23, the stirring rod 24 can be effectively driven to slowly mix the various raw materials in the mixing chamber 32.

[0025] The technical effects brought about by the above technical solution are as follows: by setting multiple feeding cylinders 33, it is convenient to add multiple raw materials in stages during the mixing process. Compared with traditional feeding equipment, this method effectively avoids uneven distribution of pigments or additives, which may lead to uneven color or performance differences on the product surface.

[0029] As a preferred technical solution in this embodiment: In actual use, when the raw materials in the mixing chamber 32 are mixed, they fall into the feeding hopper 124 through the discharge pipe 34. At this time, the operator can control the transmission motor 121 to drive the transmission rod 122 to rotate. During the rotation of the transmission rod 122, it can drive the auger blade 123 to transport the raw materials to the discharge chamber 17.

[0031] The working principle of the above embodiments is as follows:

[0032] 1. In actual use, the operator can put different raw materials into the feeding cylinder 33, and then control the feeding cylinder 33 to add various raw materials into the mixing chamber 32 according to the usage requirements.
