Description

Technical Field

[0001] The utility model relates to the technical field of nylon slices, in particular to a granulating device for regenerated nylon slices. Background Art

[0002] High temperature resistant nylon chips are a material with high temperature stability and excellent mechanical properties. It is usually used for cutting, grinding and processing in high temperature environments. It has the characteristics of high temperature resistance, high mechanical strength, strong corrosion resistance, good friction performance, etc. It is widely used in the fields of automobiles, aerospace, electronics, chemicals, etc. Common uses include the manufacture of high temperature seals, bearings, gears, pipe connectors, etc. When using high temperature resistant nylon chips, it is necessary to select appropriate material specifications and processing technology according to the specific application environment and requirements. The nylon chip granulation requires the material to be placed in the extrusion barrel, and the finished product is extruded after processing. The bottom of the extrusion barrel used for granulation production is vertical to the material connection surface. It is inconvenient to adjust the angle of the extrusion barrel. In addition, the processing cutting knife needs to be properly repaired and replaced when used.

[0003] For example, in a granulation device for recycled nylon slices disclosed on the Chinese Patent Network (application number: 202020405985.7), when cutting nylon slices, although the problem of conveniently adjusting the angle of the extrusion barrel and quickly replacing the cutting knife is solved, the nylon slice raw material inside the extrusion barrel needs to be manually extruded with a piston, and then the servo motor is used to control the cutting knife to cut the extruded raw material. This will cause many problems. For example, the amount of raw material extruded each time cannot be guaranteed to be the same, resulting in different sizes of particles. Secondly, each cutting requires the use of a piston to extrude the material, which is inconvenient to use. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 3 A granulation device for recycled nylon slices includes an extrusion box 1. In order to facilitate the extrusion of materials out of the extrusion box 1 and the cutting of materials, a cutting device is arranged below the extrusion box 1. The cutting device includes a cylinder 2 installed below the extrusion box 1 and a cutting blade 3 installed above the front end of the cylinder 2. When the cylinder 2 is started, it drives the cutting blade 3 to move horizontally and linearly. The cutting blade 3 moves horizontally to cut the material extruded from the extrusion box 1.

[0024] In order to facilitate the control of the gas rod 21 to move horizontally back and forth, the cylinder 2 is fixedly installed on the lower surface of the extrusion box 1. The cylinder 2 includes a gas rod 21 and a cylinder body 22. The upper surface of the cylinder body 22 is fixedly connected to the lower surface of the extrusion box 1. The interior of the extrusion box 1 is fixedly installed with a mounting cross plate 11. When the cylinder 2 is started, the gas rod 21 moves horizontally back and forth at the front end of the cylinder body 22. The mounting cross plate 11 divides the interior of the extrusion box into two cavities.

[0025] In order to facilitate the material to fall from the lower end of the extrusion box 1 to the bottom of the mounting cross plate 11, a material passing pipe 12 is fixedly connected to the inside of the upper end of the extrusion box 1. The outer surface of the lower end of the material passing pipe 12 is fixedly connected to the inside of the mounting cross plate 11. The lowermost end of the material passing pipe 12 is flush with the middle position of the mounting cross plate 11 in the vertical direction. The material is passed into the extrusion box 1 through the material passing pipe 12, and the material falls from the lower end of the extrusion box 1 to the bottom of the mounting cross plate 11.

[0026] In order to facilitate the control of the movement of the sliding plate 13 to block the opening of the feed pipe 12, the sliding plate 13 is slidably inserted inside the installation cross plate 11, and a bending rod 23 is fixedly installed on the lower surface of the gas rod 21. The upper surface of the other end of the bending rod 23 is fixedly connected to the lower surface of the sliding plate 13, and the outer surface of the sliding plate 13 is slidably connected to the right end of the extrusion box 1. When the cylinder 2 is started, the gas rod 21 drives the bending rod 23 to move, and the bending rod 23 drives the sliding plate 13 to move horizontally, and the sliding plate 13 moves to the bottom of the feed pipe 12 to block the pipe opening.

[0027] In order to facilitate the control of the cutting blade 3 to cut the material coming out of the feed hole 14, the cutting blade 3 is fixedly installed on the upper surface of the gas rod 21, and the upper surface of the cutting blade 3 is slidably connected to the lower surface of the extrusion box 1. The lower end of the extrusion box 1 is provided with a feed hole 14, and the feed hole 14 is located slightly in front of the cutting blade 3. The gas rod 21 drives the cutting blade 3 to move to cut the material coming out of the feed hole 14.

[0028] In order to facilitate the material to enter the discharge hole 14 more smoothly, a fixed block 15 is fixedly installed between the lower inner wall of the extrusion box 1 and the mounting cross plate 11. The fixed block 15 is located on the left side of the discharge hole 14. A fixed round rod 24 is fixedly installed on the outer surface of the bending rod 23. The outer surface of the fixed round rod 24 is slidably connected to the inside of the right end of the extrusion box 1. An extrusion plate 25 is fixedly installed on the left end surface of the fixed round rod 24. The upper and lower surfaces of the extrusion plate 25 are respectively slidably connected to the lower surface of the mounting cross plate 11 and the lower inner wall of the extrusion box 1. The bending rod 23 drives the fixed round rod 24 and the extrusion plate 25 to move, so that the extrusion plate 25 squeezes the material. The inclined surface on the fixed block 15 can allow the material to enter the discharge hole 14 more smoothly.

[0029] By setting a cutting device, when nylon slice particles are produced, the material is passed into the extrusion box 1 through the feed pipe 12, and the material falls from the lower end of the extrusion box 1 to the bottom of the mounting cross plate 11. When cutting, the cylinder 2 is started, and the gas rod 21 drives the bending rod 23 to move, and the bending rod 23 drives the sliding plate 13, the fixed round rod 24 and the extrusion plate 25 to move horizontally at the same time. After moving a distance, the sliding plate 13 moves to the bottom of the feed pipe 12 to block the pipe mouth, so that the material under the mounting cross plate 11 cannot enter the feed pipe 12, and then the extrusion plate 25 continues to move to extrude the material. At this time, the material can only go out from the discharge hole 14, and the gas rod 21 drives the cutting blade 3 to move to complete the cutting of the material. When the gas rod 21 returns, it can drive the sliding plate 13 to move, so that the material in the feed pipe 12 can re-enter the bottom of the mounting cross plate 11, which is convenient for the next material cutting, and the amount of material extruded each time is the same, thereby achieving the effect of ensuring that the nylon cutting granulation size is the same and convenient operation.

[0030] Working principle: When producing nylon slice particles, the material is passed into the extrusion box 1 through the feed pipe 12, and the material falls from the lower end of the extrusion box 1 to the bottom of the mounting cross plate 11. When cutting, the cylinder 2 is started, and the gas rod 21 drives the bending rod 23 to move, and the bending rod 23 drives the sliding plate 13, the fixed round rod 24 and the extrusion plate 25 to move horizontally at the same time. After moving a distance, the sliding plate 13 moves to the bottom of the feed pipe 12 to block the pipe mouth, so that the material under the mounting cross plate 11 cannot enter the feed pipe 12, and then the extrusion plate 25 continues to move to extrude the material. At this time, the material can only go out from the discharge hole 14, and at the same time, the gas rod 21 drives the cutting blade 3 to move to complete the cutting of the material. When the gas rod 21 returns, it can drive the sliding plate 13 to move, so that the material in the feed pipe 12 can re-enter the bottom of the mounting cross plate 11, which is convenient for the next material cutting.
