Description

Technical Field

[0001] This utility model relates to the field of plastic profile production equipment, and in particular to a grinding device for processing plastic profile raw materials. Background Technology

[0002] In the production of plastic profiles, raw materials typically undergo multiple processes such as conveying, grinding, and mixing to ensure their uniformity and effectiveness. Currently, traditional raw material processing methods mostly employ multiple independent machines to complete each process, with manual transfer between machines. This method has several drawbacks. On the one hand, manual transfer not only increases labor costs but also easily leads to spillage and contamination of raw materials during transport, resulting in waste and inconsistent product quality. On the other hand, multiple independent machines occupy a large area, and poor coordination between them leads to low production efficiency, making it difficult to meet the ever-increasing demand for plastic profile production.

[0027] Figures 1-3 The present invention relates to a grinding device for processing plastic profile raw materials, comprising a power transmission component 10, a raw material conveying component 20, a grinding component 30, and a stirring component 40.

[0028] In this embodiment:

[0029] The power transmission assembly 10 includes a motor 11, a gearbox 12, and a coupling 13.

[0030] The output shaft of motor 11 is connected to the input shaft of gearbox 12 to convert the high speed of motor 11 into low speed and high torque power. Coupling 13 is connected to the output shaft of gearbox.

[0031] The raw material conveying assembly 20 includes a sleeve 21, a spiral extrusion rod 22, and a feed hopper 23.

[0032] The spiral extrusion rod 22 is connected to the output shaft of the gearbox 12 via a coupling 13. A sleeve 21 is fitted over the spiral extrusion rod 22. A feed hopper 23 is located at the feed end of the spiral extrusion rod 22 and communicates with the sleeve 21, and is used to store the raw plastic profile material to be processed. In this embodiment, the pitch of the spiral blades of the spiral extrusion rod 22 gradually decreases from the feed end to the discharge end.

[0033] The grinding assembly 30 includes a fixed grinding disc 31, a rotating grinding disc 32, and a discharge cylinder 33.

[0034] The rotating grinding disc 32 is connected to the discharge end of the spiral extrusion rod 22 and is located inside the sleeve 21, and is used to grind and refine the raw materials that are conveyed.

[0035] A fixed grinding disc 31 is positioned at the end of the sleeve 21, forming a gap with the rotating grinding disc 32. The plastic profile raw material is gradually processed into finer particles through friction and extrusion between the two grinding discs. In a preferred embodiment, the gap between the fixed grinding disc 31 and the rotating grinding disc 32 is adjusted using a fine-tuning screw.

[0036] The discharge cylinder 33 is connected to the sleeve 21, and the ground raw material falls from the discharge cylinder 33 into the mixing cylinder 41.

[0037] The stirring assembly 40 includes a stirring drum 41, a stirring shaft 42, a stirring transmission component 43, and a stirring rod 44.

[0038] The mixing drum 41 is located below the discharge drum 33. The mixing drum 41 is provided with a window 411 to facilitate observation of the mixing situation and cleaning and maintenance of the inside of the mixing drum 41.

[0039] The stirring shaft 42 is located inside the stirring drum 41 and is used to thoroughly stir and mix the ground raw materials.

[0040] The stirring transmission component 43 includes a worm gear 431 and a turbine gear 432. The worm gear 431 is connected to the output shaft of the reduction gearbox 12, and the turbine gear 432 is sleeved on the outside of the stirring shaft 42. The motor 11 drives the worm gear 431 to rotate through the reduction gearbox 12, which in turn drives the turbine gear 432 and the stirring shaft 42 to rotate. In this embodiment, the stirring transmission component 43 also includes a belt drive mechanism 433, which is disposed between the reduction gearbox 12 and the worm gear 431. The motor 11 drives the worm gear 431 and the turbine gear 432 to move through the reduction gearbox 12 and the belt drive mechanism 433.

[0041] The stirring rod 44 is used for manual further stirring of the plastic profile raw material in the stirring drum 41.

[0042] The working process for this application is as follows:

[0043] First, put the plastic profile raw material into the feed hopper 23, start the motor 11, and the power of the motor 11 is transmitted to the spiral extrusion rod 22 after the speed is reduced and the torque is increased by the reduction gearbox 12. The spiral extrusion rod 22 starts to rotate, and the plastic profile raw material moves towards the discharge end under the push of the spiral blades.

[0044] When the raw material reaches the discharge end, the spiral extrusion rod 22 drives the rotating grinding disc 32 to rotate, and cooperates with the fixed grinding disc 31 to grind the raw material. The ground raw material falls from the discharge cylinder 33 into the mixing cylinder 41. The motor 11 drives the worm gear 431 to rotate through the reduction gearbox 12, and drives the turbine 432 and the mixing shaft 42 to rotate, so as to fully mix the ground plastic profile raw material.

[0045] This application achieves continuous automation of plastic profile raw material processing through the coordinated operation of the power transmission component 10, the raw material conveying component 20, the grinding component 30, and the stirring component 40. It eliminates the need for manual material transfer, greatly improves production efficiency, reduces labor costs and raw material loss, and at the same time, the compact structure reduces the risk of raw material contamination and ensures the product quality of plastic profiles.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
