[0002] ABS plastic is a ternary copolymer of acrylonitrile, butadiene and styrene. The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of the three components. A makes it resistant to chemical corrosion and heat, and has a certain surface hardness. B makes it highly elastic and tough. S makes it have the processing and molding characteristics of thermoplastic plastics and improves electrical properties.
[0003] During the granulation process, an ABS plastic pellet cutter is needed to pelletize the freshly extruded ABS plastic strips. However, the existing ABS plastic pellet cutters generally only use one cutter head for cutting, and the cutter head wears out quickly. At the same time, the extruder cannot be stopped during the replacement of the blade, resulting in a large number of uncut plastic strips, which require additional effort to deal with later.
[0004] Therefore, it is urgent to develop a pelletizing device with a long blade replacement cycle and little impact on pelletizing when replacing the blade. Utility Model Content

[0008] The knife seat is symmetrically provided with knife grooves on both sides, the inner wall of the knife groove is provided with a stop strip, the cutting knife is provided with a guide groove at a position corresponding to the stop strip, and the cutting knife is fixed to the knife seat by a stud.
[0009] Preferably, in order to improve cutting stability, a track is fixed on the base, the track is arranged below the knife seat, and the knife seat can move along the track.

DETAILED DESCRIPTION
[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a high-efficiency pelletizing device for ABS plastic production, referring to Figure 1-3 , including a base 1, an L-shaped support plate 2 is fixed on the base 1, a clearance groove 21 is opened in the middle of the L-shaped support plate 2, a working chamber is formed between the L-shaped support plate 2 and the base 1, a pelletizing mechanism 3 is installed in the working chamber, and the number of the pelletizing mechanisms 3 is set to two, and the two pelletizing mechanisms 3 are symmetrically arranged on both sides of the clearance groove 21. The pelletizing mechanism 3 includes a linear guide slide 31, a mounting frame 32, a servo motor 33, a rotating disk 34, a transmission rod 35 and a knife seat 36. The linear guide slide 31 is fixed on On the L-shaped support plate 2, the mounting frame 32 is fixed on the slide on the linear guide slide 31, the end of the screw of the linear guide slide 31 is fixed with a crank 4, the servo motor 33 is fixed on the mounting frame 32, the mounting frame 32 is fixed with a slide rail 37, the tool holder 36 is slidably connected to the slide rail 37, the rotating disk 34 is fixed on the output shaft of the servo motor 33, one end of the transmission rod 35 is eccentrically hinged on the rotating disk 34, and the other end is hinged on the tool holder 36, and the cutters 38 are symmetrically fixed on both sides of the tool holder 36.
[0020] Reference Figure 3 The knife seat 36 has knife grooves 361 symmetrically formed on both sides, the inner wall of the knife groove 361 has a stop bar, and the cutter 38 has a guide groove corresponding to the position of the stop bar. The cutter 38 is fixed to the knife seat 36 by a stud. This installation structure of the cutter 38 not only has a good fixing effect of the cutter 38, but also facilitates the replacement of the cutter 38.
[0021] Reference Figure 1 In order to ensure that the knife seat 36 can run smoothly, a track 5 is fixed on the base 1. The track 5 is arranged below the knife seat 36, and the knife seat 36 can move along the track 5.
[0022] The implementation principle of an efficient pelletizing device for ABS plastic production in the present application embodiment is as follows:
[0023] The pelletizing device is fixed at the extrusion port of the extruder through the clearance groove 21, leaving a small gap for the operation of the cutter 38. After that, the servo motor 33 drives the cutter seat 36 to move forward and backward through the rotating disk 34 and the transmission rod 35. During the forward and backward movement of the cutter seat 36, the cutters 38 located on both sides of the cutter seat 36 cut the particle strips extruded on its path respectively. The two cutters 38 cut alternately, which can reduce the wear speed of the cutter 38, thereby reducing the replacement cycle of the blade, and further reducing the impact on the pelletizing efficiency.
