Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch grinding, in particular to a grinding device for masterbatch production. Background Technique

[0002] Masterbatch, also called color masterbatch or color concentrate, is a new type of special coloring agent for polymer materials, also known as pigment preparation. Its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is blended with uncolored resin to achieve the colored resin or product with the designed pigment concentration.

[0003] At present, there are certain defects in the grinding device for masterbatch. A new type of grinding device for masterbatch production proposed in the patent number "202123188188.1" disperses the material onto the side plate, and the push-pull structure can push the side plate. As a result, the two side plates are in an inclined state, and the material on their upper surfaces falls back onto the upper surface of the middle plate for re-grinding, with repeated grinding. However, in actual situations, after the grinding is completed, the ground masterbatch is collected through a suction hopper. The suction angle of the suction hopper is fixed, and the masterbatch at the corners cannot be sucked in, resulting in waste of resources. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a grinding device for masterbatch production is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A grinding device for masterbatch production includes a device block. A grinding groove is opened at the upper end of the device block. Two electric telescopic rods are fixedly connected to the outer wall of the device block. The telescopic ends of the two electric telescopic rods are fixedly connected to a top plate. A servo motor is fixedly connected to the lower end of the top plate. The output shaft of the servo motor is fixedly connected to a grinding block. A device cavity is opened on the inner wall of the grinding groove. A sliding plate is slidably connected in the device cavity. A material blocking plate is fixedly connected to the lower end of the top plate. A sliding mechanism for sliding the sliding plate is installed in the device cavity.

[0007] Preferably, the sliding mechanism includes a lead screw sleeve slidably connected in the device cavity. Two connecting rods are fixedly connected to the outer wall of the lead screw sleeve. The two connecting rods are fixedly connected to the sliding plate.

[0008] Preferably, a reciprocating lead screw is rotatably connected in the device cavity. The lead screw sleeve is threadedly connected to the threaded section of the reciprocating lead screw.

[0009] Preferably, a gear is fixedly connected to the outer wall of the reciprocating lead screw. A rack is fixedly connected to the lower end of the top plate. A chute is opened at the bottom of the device cavity.

[0010] Preferably, the rack is slidably connected in the chute, the gear meshes with the rack, and one end of the reciprocating lead screw is fixedly connected with a limiting block.

[0011] Preferably, a discharge chute is formed in the inner wall of the grinding groove, a placement groove is formed in the outer wall of the device block, the discharge chute communicates with the placement groove, and a collection box is slidably connected in the placement groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. By arranging components such as a reciprocating lead screw, a lead screw sleeve, and a sliding plate, through the contraction of the telescopic end of the electric telescopic rod, the reciprocating lead screw can be driven to rotate forward and backward by the gear. When the reciprocating lead screw rotates forward, the sliding plate can be retracted into the device cavity to avoid affecting the grinding of the masterbatch by the grinding block. When the reciprocating lead screw rotates backward, the sliding plate can be driven to slide outwards through the lead screw sleeve, so that the ground masterbatch can be pushed into the collection box through the sliding plate, thus collecting the masterbatch in the dead corner and avoiding waste of resources.

[0014] 2. By arranging a discharge chute and a collection box, the ground masterbatch can slide into the arranged collection box through the arranged discharge chute, so that the ground masterbatch can be quickly extracted, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
