Description

Technical Field

[0001] The utility model relates to the technical field of modified plastic production, in particular to a continuous cutting mechanism for modified plastics during extrusion. Background Art

[0002] Modified plastics, which are intermediate products in the petrochemical industry chain, refer to plastic products that have been processed by methods such as filling, blending, and reinforcement on the basis of general plastics and engineering plastics, and have improved performance in aspects such as flame retardancy, strength, impact resistance, and toughness. In recent years, the modified plastic industry in China has developed rapidly, so a large amount of modified plastics need to be produced to meet the demand.

[0003] Chinese Publication No.: CN218052976U discloses a continuous cutting mechanism for modified plastics during extrusion with a novel structural design. This utility model drives a rotating rod and a gear to rotate through a motor. During the rotation of the gear, the push rod is driven to move by meshing with a moving seat. When the push rod moves, it can drive a movable rod and a cutting blade to move, thereby realizing the function of continuous cutting of materials. However, this device can only cut one extruded modified plastic and cannot cut modified plastics in batches. Moreover, when the modified plastics are extruded, the temperature is very high and the texture is relatively soft. When cutting them, there will be a situation where they stick together and cannot be separated or are deformed after cutting. They need to be cooled to room temperature before they will not stick together. Summary of the Utility Model

A pair of first chutes are correspondingly provided on the front and rear walls of the box body. Sliding blocks are provided at both ends of the lifting plate and are slidably connected with the first chutes.

[0010] Furthermore, the height of the top end of the knife holder is the same as the height of the top end of the horizontal conveying assembly. A knife groove for cooperating with the knife plate is provided at the bottom end of the knife holder.

[0011] Furthermore, the positioning assembly includes a hydraulic cylinder installed at the top end of the box body. The piston rod of the hydraulic cylinder passes through the top wall of the box body and is connected to a U-shaped plate.

[0013] III. Beneficial Effects

[0014] The advantages of the present utility model compared with the prior art are as follows:

[0015] 1. The conveyor belt drives multiple pieces of modified plastics to move. The extrusion rate of the modified plastics is the same as the moving rate of the conveyor belt, which is convenient for batch cutting of the modified plastics and improves the cutting rate of the modified plastics.

[0016] 2. The modified plastics on the conveyor belt are cooled by the cooperation of the air inlet pipe and the fan, so that the texture of the modified plastics becomes hard, preventing the situation of adhesion and inseparability during cutting or deformation after cutting.

[0017] 3. The positioning assembly, that is, the hydraulic cylinder drives the U-shaped plate to descend, so that the positioning rotating cylinder presses on the top end of the modified plastics, thus facilitating the positioning of the modified plastics with different heights and facilitating cutting.

[0018] 4.

Inside the box body 1, a horizontal conveying assembly 2 and a support platform 3 are installed between the front and rear walls. The support platform 3 is located at the left end of the horizontal conveying assembly 2. An installation block 4 is fixed on the upper end of the support platform 3. A tool holder 5 is installed on the installation block 4. A continuous cutting assembly 6 installed on the box body 1 is provided at the upper end of the tool holder 5. A positioning assembly 7 installed on the box body 1 is provided on the left side of the upper end of the horizontal conveying assembly 2. A plurality of air inlet pipes 8 are installed on the upper end of the box body 1, and a fan 9 is installed inside the air inlet pipes 8.

[0028] Combined with the above structure, the modified plastic is placed on the horizontal conveyor assembly 2, and is cooled through the cooperation of the air inlet pipe 8 and the fan 9, so that the modified plastic becomes hard in texture, preventing adhesion or deformation during or after cutting.

[0029] Combined with the attached Figure 1 and the attached Figure 2 The horizontal conveyor assembly 2 includes a plurality of rotating cylinders 10 that are connected to the front and rear walls of the box body 1 by bearings. A conveyor belt 11 is wound around the outside of the plurality of rotating cylinders 10, and a conveyor motor 12 connected to the rightmost rotating cylinder 10 is installed on the right side of the front end of the box body 1.

[0030] Combined with the above structure, the extrusion rate of the modified plastic is consistent with the moving rate of the conveyor belt 11. The rotating cylinder 10 is driven by the conveyor motor 12, so that the conveyor belt 11 moves outside the plurality of rotating cylinders 10, and the conveyor belt 11 drives multiple modified plastics to move, facilitating batch cutting of the modified plastic and improving the cutting rate of the modified plastic.

[0031] Combined with the attached Figure 4 and the attached Figure 3 The continuous cutting assembly 6 includes a cutting motor 13 installed at the left end of the top wall inside the box body 1. The right output end of the cutting motor 13 is connected to a turntable 14. An articulated rod 15 is fixed on the outside of the right end of the turntable 14.

The conveyor belt 11 on the leftmost rotating cylinder 10 supports the modified plastic, so as to position the modified plastic and facilitate cutting; and it is convenient to position the modified plastic with different heights.

[0036] Combined with the attached Figure 2 , a motor speed regulator 24 electrically connected to the cutting motor 13 is installed at the front end of the box body 1, which is convenient for adjusting the rotation speed of the cutting motor 13, so as to change the cutting rate and is suitable for cutting modified plastics with different lengths; a control panel 25 electrically connected to the horizontal conveying assembly 2, the continuous cutting assembly 6, the positioning assembly 7, and the blower 9 is installed at the front end of the box body 1.
