Description

Technical Field

[0001] The utility model relates to the technical field of plastic powder feeding, and more specifically, to a feeding device for plastic powder processing. Background Art

[0002] Plastic powder, plastic ultrafine powder, resin powder Plastic is a synthetic high molecular compound, also known as polymer or macromolecule, also commonly known as plastic or resin, which can change its shape freely. It is a material made by synthesizing or condensing monomer raw materials, composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] In the process of plastic powder processing, operations such as crushing, stirring, and extrusion are required, and before the plastic powder needs to be processed, it needs to be transported and loaded through a loading device, so that the loading device transports the plastic powder to the designated equipment for processing.

[0004] The prior art requires that the plastic powder to be crushed is crushed by a crusher, and the feeding device transports large and small and uneven-sized plastic powder blocks to the crusher, which will result in insufficient crushing by the crusher and prolonged crushing time, thus affecting the efficiency of plastic powder processing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a feeding device for plastic powder processing, which can perform preliminary grinding and crushing of the plastic powder before it enters a crusher to improve the processing efficiency of the plastic powder.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a feeding device for plastic powder processing, including a crusher and a feeding device arranged on the crusher, the feeding device including a support frame, a conveyor belt arranged on the support frame and a grinding structure arranged on the conveyor belt on the support frame, the grinding structure including a fixed disk fixedly connected to the support frame, a first grinding block and a second grinding block rotatably connected to the support frame, and a fixed grinding block fixedly connected to the conveyor belt, the first grinding block is arranged at one end away from the center of the fixed disk, the first grinding block is restricted between the second grinding block and the fixed grinding block, and the support frame is provided with a first rotating member and a second rotating member for respectively driving the first grinding block and the second grinding block to rotate.

[0007] By adopting the above technical scheme, the plastic powder blocks that need to be crushed are placed on the loading device, and as the conveyor belt continuously transmits, the plastic powder blocks can be driven to enter the position of the fixed disk first, and the first grinding block and the second grinding block can be driven to rotate at the position of the fixed disk respectively by the driving of the first rotating member and the second rotating member, and rotate on the conveyor belt at the same time. The first grinding block and the second grinding block will contact each other and the fixed grinding block during the rotation, so that when the plastic powder blocks transported by the conveyor belt enter the position of the fixed disk, they will contact between the first grinding block and the fixed grinding block and between the second grinding block and the fixed grinding block to achieve the effect of dispersion and preliminary crushing. After the distribution and preliminary crushing, the plastic powder blocks will continue to enter the crusher with the transmission of the conveyor belt, thereby preventing a large number of plastic powder blocks and plastic powder blocks with large size differences from entering the crusher, so that the plastic powder blocks that have been initially dispersed and crushed can be crushed more fully when crushed, and the crushing time will be further reduced, thereby ensuring the efficiency and quality of plastic powder block processing.

[0008] The utility model is further configured as follows: a plurality of first protrusions are protrudingly provided on the four sides of the first grinding block, a second protrusion matching with the plurality of first protrusions is provided on the second grinding block, a recessed groove matching with the second protrusions is provided between adjacent first protrusions, and the first protrusions and the second protrusions approach the fixed grinding block as they rotate.

[0009] By adopting the above technical solution, the first protrusion is integrated with the first grinding block and is protrudingly arranged on the first grinding block, and the second protrusion is integrated with the second grinding block and is protrudingly arranged on the second grinding block. As the first and second grinding blocks rotate and contact with the fixed grinding block, and at the same time, when the second protrusion of the second grinding block cooperates with the recessed groove, the end of the first grinding block away from the fixed grinding block is in a closed state and cannot pass through the plastic powder block, so that the plastic powder block can not only achieve the effect of crushing and grinding as the first and second grinding blocks rotate, but also guide the plastic powder block, so that the plastic powder block still moves along the transportation direction of the conveyor belt, and at the same time can have a diversion effect on a large amount of plastic powder, preventing a large amount of plastic powder from entering the crusher all at once, causing the crusher to be overburdened and affecting the crushing efficiency and effect.

[0010] The utility model is further configured such that: the first grinding block is in close contact with the surface of the conveyor belt.

[0011] By adopting the above technical solution, there is no gap between the first grinding block and the conveyor belt for the plastic powder blocks to pass through. As the first grinding block rotates, it can not only preliminarily crush the plastic powder blocks, but also play a certain blocking role on the plastic powder blocks to prevent the plastic powder blocks from entering the bottom of the first grinding block.

[0012] The utility model is further configured as follows: a plurality of gaps are provided on the second grinding block, and a plurality of the gaps and the second protrusions are distributed on the second grinding block at intervals.

[0013] By adopting the above technical solution, a plurality of gaps and a plurality of second protrusions are distributed at intervals, so that the plastic powder block can enter the position where the fixed disk is set from the position of the plurality of gaps, and then the plastic powder block is initially ground and crushed by the action of the first grinding block and the second grinding block, thereby reducing the time for the plastic powder to enter the crusher for crushing, and at the same time the plastic powder can be crushed more fully and evenly.

[0014] The utility model is further configured as follows: the first rotating member comprises a first motor arranged on a supporting frame, and an output shaft of the first motor is fixedly connected to a first grinding block.

[0015] By adopting the above technical solution, the first motor is started to drive the first grinding block to rotate on the conveyor belt, and continuously cooperate with the second grinding block, so that the first grinding block and the second grinding block are constantly approaching and moving away from each other, and at the same time, the first grinding block is always in contact with the fixed grinding block to improve the effect of dispersing and crushing the plastic powder block.

[0016] The utility model is further configured as follows: the second rotating member includes a second motor arranged on a support frame, a plurality of connecting rods are fixedly connected to the second grinding block, a connecting disk is fixedly connected between the plurality of connecting rods, and an output shaft of the second motor is fixedly connected to the connecting disk.

[0017] By adopting the above technical solution, the second motor is started to drive the connecting disk to rotate on the support frame. As the connecting disk rotates, several connecting rods on the connecting disk also rotate accordingly, and the second grinding block connected by the several connecting rods also rotates accordingly, so that the second grinding block rotates on the conveyor belt and contacts with the fixed disk and the fixed grinding block, and the first motor and the second motor will not affect each other, and the movements of the first grinding block and the second grinding block will not affect each other.

[0018] The utility model is further configured as follows: a grinding plate is arranged at one end of the support frame close to the conveyor belt, and an electric push rod for driving the grinding plate to approach the conveyor belt is arranged on the support frame.

[0019] By adopting the above technical solution, the electric push rod and the grinding plate can be arranged before the plastic powder block passes through the grinding structure, or at the position where it passes through the grinding structure. The grinding plate is driven close to the conveyor belt by the extension of the electric push rod, and the plastic powder blocks on the conveyor belt are initially pressed and crushed, thereby preventing the plastic powder blocks from being uneven due to excessive size differences, which makes it take more time for the plastic powder blocks to enter the crusher for crushing.

[0020] In summary, the utility model has the following beneficial effects: under the action of the conveyor belt and the grinding structure, the plastic powder can be preliminarily ground and crushed before entering the crusher, so that the block shape of the plastic powder will not be particularly uneven, and the plastic powder does not need to spend much time when entering the crusher for further processing, thereby improving the processing efficiency of the plastic powder.
