Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an extrusion and slitting device for PTC ceramic materials. Background Technology

[0002] PTC ceramic material is a type of ceramic material with special properties. Its production process includes two indispensable steps: mixing and sintering.

[0003] In the existing technology, when transferring the mixture to sintering, it is necessary to manually load the plastic solid mixture into the sintering carrier. The sintering carrier has two placement slots, and the mixture is manually placed in with a shovel. This method has two main problems: first, it is difficult to accurately control the amount of material, and second, the operation process is relatively cumbersome. Therefore, it is necessary to design an extrusion and slitting device for PTC ceramic materials. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an extrusion and slitting device for PTC ceramic materials.

[0005] The objective of this utility model can be achieved through the following technical solution: An extrusion and slitting device for PTC ceramic materials, characterized in that it includes an extruder, a conveyor belt, and an operating table. One end of the conveyor belt is close to the extruder, and the other end of the conveyor belt is close to the operating table. The extruder has an extrusion die, and an L-shaped bracket is fixed on the extruder. The L-shaped bracket is located above the extrusion die. A cylinder is mounted on the L-shaped bracket, and the piston rod of the cylinder is vertically downward. The end of the piston rod of the cylinder is connected to the middle of a U-shaped part. A cutting component is horizontally connected between the two ends of the U-shaped part. A second cylinder is also mounted on the extruder, and the piston rod of the second cylinder is horizontally arranged. The end of the piston rod of the second cylinder is connected to an inclined auxiliary guide platform, and the auxiliary guide platform is located below the extrusion die.

[0006] An electrical control box is also installed at the control panel, and cylinder one and cylinder two are electrically connected to the electrical control box via wiring.

[0007] The control panel is T-shaped.

[0008] The cutting component is a steel wire rope or a cutting blade.

[0009] The auxiliary guide platform is made of stainless steel plate.

[0010] Compared with existing technologies, this extrusion and slitting device for PTC ceramic materials has the following advantages:

[0011] In this invention, the mixture is extruded using an extruder and cut into small pieces using a cutter. With the assistance of an auxiliary guide platform, it is ensured that every two pieces of material on the conveyor belt are arranged in a row. On the operating table, the operator can easily grab a piece of material with each hand and place it into the sintering carrier. The whole process is simple to operate. Attached Figure Description

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1-Figure 3As shown, this PTC ceramic material extrusion and slitting device includes an extruder 1, a conveyor belt 7, and an operating table 9. One end of the conveyor belt 7 is close to the extruder 1, and the other end is close to the operating table 9. In this embodiment, the conveyor belt 7 is an existing product that can operate intermittently as needed. The extruder 1 has an extrusion die 2, and an L-shaped bracket 5 is fixed on the extruder 1. The L-shaped bracket 5 is located above the extrusion die 2, and a cylinder 6 is installed on the L-shaped bracket 5. The piston rod of the cylinder 6 is vertically downward, and the end of the piston rod of the cylinder 6 is connected to the middle of a U-shaped part 3. A cutting element 11 is horizontally connected between the two ends of the U-shaped part 3. With this structure, the cylinder 6... 6 drives the U-shaped part 3 to move up and down, and the U-shaped part 3 drives the cutting part 11 to move up and down, which can cut the mixture at the extrusion die 2 into blocks; the extruder 1 is also equipped with a second cylinder 10, and the piston rod of the second cylinder 10 is arranged horizontally. The end of the piston rod of the second cylinder 10 is connected to an auxiliary guide platform 4 arranged at an inclination, and the auxiliary guide platform 4 is located below the extrusion die 2. Specifically, the auxiliary guide platform 4 is made of stainless steel plate; with this structure, the auxiliary guide platform 4 is extended by the second cylinder 10. Under the action of the auxiliary guide platform 4, the cut blocks can be transferred to the side of the conveyor belt 7 away from the extruder 1, so that two blocks can be distributed on the same row on the conveyor belt.

[0019] An electrical control box 8 is also installed at the control panel 9. Cylinder 1 6 and Cylinder 2 10 are electrically connected to the electrical control box 8 via wiring. This uses existing technology, and its circuits do not need to be redesigned.

[0020] The control panel 9 is T-shaped.

[0021] Cutting component 11 is a steel wire rope or a cutting blade.

[0022] In this invention, the mixture is extruded using an extruder 1 and cut into small pieces using a cutter 11. With the assistance of the auxiliary guide platform 4, it is ensured that every two pieces of material on the conveyor belt are arranged in a row. On the operating platform 9, the operator can easily grab a piece of material with each hand and place it into the sintering carrier. The whole process is simple to operate.

[0023] In this embodiment, the effect of loading the sintering carrier during the completion of the operation is as follows: Figure 4 As shown.
