Description

Technical Field

[0001] This utility model relates to the technical field of plastic masterbatch pelletizers, specifically to a pelletizer for producing modified plastic masterbatch. Background Technology

[0002] Plastic masterbatch is a plastic processing aid composed of excessive amounts of chemical additives, carrier resin, and dispersants. It is an aggregate obtained by uniformly loading excessive amounts of pigment into resin. Masterbatch refers to the granular material produced during plastic processing, where various additives, fillers, and a small amount of carrier resin are mixed and kneaded beforehand, and then processed through extrusion equipment such as metering, mixing, melting, extrusion, and pelletizing. Current plastic masterbatch pelletizing machines use rotary cutters for pelletizing. However, if one of the cutters is damaged, the entire cutter needs to be disassembled and replaced, resulting in waste. Therefore, this paper proposes a modified plastic masterbatch pelletizing machine to solve this problem. Utility Model Content

[0003] To solve the problems mentioned above, the technical solution adopted by this utility model is: a pelletizer for producing modified plastic masterbatch, comprising: a frame and a pelletizing roller assembly, wherein the pelletizing roller assembly includes a cutter roller, a cutter mounting groove, a cutter seat, and a cutter head, the cutter mounting groove is opened on the outer side of the circumference of the cutter roller, the cutter seat is disposed at the tail of the cutter head, and wedges are fixedly connected to both ends of the cutter mounting groove by screws, and matching grooves are opened on one side of each wedge at both ends of the cutter mounting groove.

[0004] As a preferred technical solution of this utility model, the frame is fixedly installed on the base, and the base has a feeding port on the side facing the cutter roller.

[0005] As a preferred technical solution of this utility model, the inside of the cutter mounting groove is a convex-shaped structure, and the number of cutter mounting grooves corresponds one-to-one with the number of cutter heads. The inside of the cutter mounting groove fits snugly to the inside of the cutter seat.

[0006] As a preferred embodiment of this utility model, the two ends of the cutter roller are connected to the inside of the frame through bearings, and one end of the cutter roller extends outside the frame and is connected to a drive gear.

[0007] As a preferred technical solution of this utility model, a feeding roller is connected to the inside of the frame near the cutter roller via a bearing. The outer circumference of the feeding roller is provided with an anti-slip stripe structure. One end of the feeding roller extends outside the frame and is connected to a driven gear. The driven gear meshes with the drive gear.

[0008] As a preferred embodiment of this utility model, the other end of the cutter roller extends out of the frame and is connected to a pulley. Inside the frame, a cutting table is provided between the cutter roller and the feed roller, and a gap is reserved between the cutting table and the cutting head.

[0009] This utility model has the following advantages: The pelletizer adopts a detachable method for the cutter roller and the cutter head. Therefore, it is only necessary to unscrew the screw at the wedge to remove the wedge, and then replace the corresponding cutter head. This effectively avoids the disadvantage of having to replace the entire roller when one blade is damaged, thus saving costs. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figures 1-4 This utility model discloses a pelletizer for producing modified plastic masterbatch, comprising: a frame 2 and a pelletizing roller assembly. The pelletizing roller assembly includes a cutter roller 3, a cutter mounting groove 5, a cutter seat 6, and a cutter head 7. The cutter mounting groove 5 is opened on the outer circumference of the cutter roller 3, and the cutter seat 6 is located at the tail of the cutter head 7. Both ends of the cutter mounting groove 5 are fixedly connected to wedges 9 by screws, and both ends of the cutter mounting groove 5 are provided with matching grooves 8 on one side corresponding to the wedges 9.

[0019] Combination Figure 1 and Figure 3 As shown, the frame 2 is fixedly mounted on the base 1. The base 1 has a feeding port 12 on the side facing the cutter roller 3. The cutter mounting groove 5 has a convex structure inside. The number of cutter mounting grooves 5 and cutter heads 7 are provided one-to-one. The cutter mounting groove 5 fits snugly inside the cutter seat 6, thereby installing or removing the cutter seat 6.
