Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for processing plastic products. Background Art

[0002] During the manufacturing process of plastics, synthetic resins and various additives are made through processes such as stirring, heating and melting, and extruder molding. There are many kinds of additives in plastic raw materials, including fillers, plasticizers, stabilizers, lubricants, colorants, etc. Therefore, a plastic mixer is needed to mix the raw materials evenly before heating and melting to ensure the quality of plastic products.

[0003] Traditional plastic raw material stirring devices are generally simple in design, and only use multi-rod components to stir in a single horizontal direction, which has a stirring dead angle. In addition, due to the different densities of the raw materials, the single stirring direction can easily cause the raw materials to stratify, resulting in insufficient stirring. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a stirring device for processing plastic products, which overcomes the deficiencies of the prior art and effectively solves the problem of dead corners in stirring in the prior art, and the problem that the raw materials are easily stratified due to different densities and a single stirring direction, resulting in insufficient stirring.

[0007] By opening the sealing cover, feeding materials into the mixing drum through the feeding pipe, and then closing the sealing cover, the servo motor drives the rotating shaft to rotate, thereby rotating the stirring mechanism, so that the stirring mechanism stirs the raw materials in the mixing drum, and the first stirring rod and the second stirring rod rotate in the vertical direction, so that the raw materials are turned up and down in the mixing drum, which is conducive to ensuring sufficient mixing of raw materials with different densities. After the stirring is completed, the insert block is lifted upward by the shifting block and the telescopic spring is contracted, so that the insert block is pulled out from the pulling block, and then the baffle can be pulled out from the discharge port, and the mixed material in the mixing drum can be poured out.

[0008] Preferably, a through hole is provided on the top of the outer wall on one side of the fixing plate and on the outer wall on one side of the mixing drum, and the through hole is rotatably matched with the rotating shaft through a bearing.

[0009] The rotating shaft rotates freely in the through hole through the bearing, so that the stirring mechanism can perform stirring operation in the stirring barrel.

[0010] Preferably, a servo motor is installed on the other side of the top of the fixed plate, and the output shaft of the servo motor is connected and fixed to one end of the rotating shaft.

[0011] The servo motor drives the rotating shaft to rotate, thereby rotating the stirring mechanism.

[0016] Preferably, a shift block is fixed to one side outer wall of the insert block, and the length of the shift block is greater than the width of the pull block.

[0017] By lifting the shifting block, the inserting block can be pulled out from the pulling block, and then the baffle can be pulled out from the discharge port.

[0018] Preferably, one side outer wall of the fixed block is fixed to the outer wall of the mixing drum, and a limiting block is fixed to the top of the insertion rod, and the telescopic spring is located between the fixed block and the insertion block.

[0019] The limit block provided can prevent the insertion rod from being separated from the bottom of the fixed block, and the telescopic spring can ensure that the insertion block always remains in the plugged state with the pulling block without being disturbed by upward external force.

[0020] The beneficial effects of the utility model are:

[0021] The stirring mechanism is rotated by the servo motor to stir the raw materials in the mixing drum. The first stirring rod and the second stirring rod are rotated in the vertical direction to turn the raw materials up and down in the mixing drum, which is conducive to ensuring sufficient mixing of raw materials with different densities. After the stirring is completed, the insert block is lifted upward by the dial block and the telescopic spring is contracted to pull the insert block out of the pull block, and then the baffle can be pulled out from the discharge port, and the mixed material in the mixing drum can be poured out, which effectively solves the problem of dead corners in stirring in the prior art, and the problem of insufficient stirring caused by stratification of raw materials due to different densities of raw materials and a single stirring direction.

[0030] A through hole is provided at the top of the outer wall on one side of the fixed plate 2 and at the outer wall on one side of the mixing drum 4. The through hole is rotatably matched with the rotating shaft 9 through a bearing. The rotating shaft 9 rotates freely in the through hole through the bearing, so that the stirring mechanism 6 can perform stirring operation in the mixing drum 4. A servo motor 3 is installed on the other side of the top of the fixed plate 2. The output shaft of the servo motor 3 is connected and fixed to one end of the rotating shaft 9.
