Description

Technical Field

[0001] The utility model relates to the technical field of polymer material grinding, in particular to a grinding device. Background Art

[0002] Polymer materials are materials based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular mass, including rubber, plastic, fiber, coating, adhesive and polymer-based composite materials. Polymers are a form of life existence. Polymer materials mainly include plastic, rubber, fiber, film, adhesive and coating. When producing polymer materials, grinding equipment is needed to grind the raw materials to ensure that the raw materials are in granular form, which is conducive to the melting and mixing of the raw materials.

[0003] In the process of grinding the raw materials of polymer materials, due to the limitations of grinding time or grinding amount, the polymer particles of some raw materials may not be fully ground, that is, this part of the raw materials cannot pass through the leakage plate and enter the bottom bin. Therefore, it is necessary to collect this part of the raw materials, and then add this part of the raw materials to the grinding mechanism for secondary grinding until the leakage size of the leakage plate is reached. In the process of secondary grinding, it is necessary to screen and collect the raw materials that are not fully ground, and then add this part of the raw materials back to the grinding mechanism through the circulating rotation mechanism, which takes a certain amount of time, and the original grinding process needs to be shut down during this process, which greatly increases the time of a single grinding, thereby delaying the subsequent melt processing process.

[0004] Therefore, it is necessary to invent a grinding device to solve the above problems. Summary of the invention

[0005] In order to solve the shortcomings of the prior art, the purpose of the utility model is to provide a grinding device, which solves the problem that in the prior art, during the secondary grinding process, it is necessary to screen and collect the insufficiently ground raw materials, and then add this part of the raw materials back to the grinding mechanism through a circulating rotation mechanism, which takes a certain amount of time and requires the original grinding process to be shut down during the process, resulting in a significant increase in the time of a single grinding, thereby delaying the subsequent melting processing process.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A grinding device comprises a bottom bin with an open top for collecting materials and a rotating plate rotatably arranged above the bottom bin, a material leakage plate being detachably embedded in the center of the rotating plate, a first rotating component with a controllable distance being longitudinally slidably arranged at the top of the rotating plate, a grinding roller being rotatably connected to the bottom end of the first rotating component for grinding materials passing through the material leakage plate, a driving gear being rotatably arranged on one side wall outside the bottom bin, a driven gear being detachably installed on one side wall adapted to the rotating plate, and the driving gear being meshingly connected to the driven gear.

[0008] As a preferred solution of the utility model, a side wall of the bottom bin away from the driving gear is connected to a limiting seat, and an auxiliary rotating wheel is detachably mounted on a side wall of the rotating plate, and the auxiliary rotating wheel can rotate along the limiting seat.

[0009] As a preferred solution of the utility model, a surrounding plate is arranged on the outer side of the top surface of the rotating plate, and a plurality of material guide grid plates are connected to the top surface of the rotating plate at positions on both sides of the leakage plate.

[0010] As a preferred solution of the utility model, the two symmetrical side walls of the rotating plate are connected to a lower side seat, a telescopic component is provided at the top of the lower side seat, the top of the telescopic component is connected to an upper side seat, a top plate is provided between the two upper side seats, the bottom end of the top plate is connected to a first mounting plate, and the first rotating component is detachably mounted on one side wall of the first mounting plate through the first mounting seat.

[0011] As a preferred solution of the utility model, a second mounting plate is installed on an outer side wall of the bottom bin, a second rotating assembly is detachably mounted on the top of the second mounting plate through a second mounting seat, and the driving gear is detachably rotatably mounted on one end of the second rotating assembly.

[0012] As a preferred solution of the utility model, a collecting bin is detachably provided in the bottom bin and can slide left and right, and both side walls outside the collecting bin are connected to lifting racks.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In the utility model, the telescopic component is longitudinally extended and retracted, thereby changing the distance between the grinding roller and the leakage plate, thereby adjusting different grinding accuracies, and driving the grinding roller to rotate above the leakage plate through the first rotating component, thereby grinding the polymer material passing through the leakage plate, and in the grinding process, some insufficiently ground raw materials will flow to the positions on both sides of the leakage plate along the rotating plate under the stirring of the grinding roller. When it is necessary to perform secondary grinding on this part of the polymer material, the driving gear is driven to rotate to drive the driven gear to rotate back and forth, so that the rotating plate rotates left and right above the bottom bin, that is, the two ends of the rotating plate are tilted back and forth, so that the two sides The raw material at the position slides along the rotating plate and reciprocates through the leakage plate position, and then is reciprocated and ground under the action of the grinding roller until all the material on the top surface of the rotating plate passes through the leakage plate and enters the bottom bin. In the utility model, without the need for shutdown and without the need for an additional circulating rotation mechanism, the reciprocating rotation of the active gear drives the reciprocating rotation of the driven gear, so that the rotating plate rotates left and right above the bottom bin, so that the raw materials located on both sides and not fully ground reciprocate through the leakage plate position, and finally are reciprocated and ground under the action of the grinding roller until they are fully ground, thereby shortening the time of a single grinding, thereby ensuring that the subsequent melting processing process is not affected.
