Description

Technical Field

[0001] The utility model relates to the field of plastic particle processing, in particular to a plastic particle melting production device. Background Art

[0002] Plastic particles are important raw materials in the plastics industry. Plastic particles usually have the characteristics of strong plasticity, light weight, corrosion resistance, and good insulation. These characteristics make them easy to process and shape during the manufacturing process and can meet the performance requirements of different products. They are widely used in the manufacture of various plastic products, such as plastic bags, plastic bottles, toys, wires and cables, auto parts, home appliance housings, etc. They not only play an important role in daily life, but also have a wide range of applications in industry, agriculture, medical care and other fields.

[0003] When plastic pellets are produced, the material strips are extruded through a plastic extruder. After being cooled in a cooling water tank, the material strips will be conveyed by conveyor rollers to a pelletizer and cut into plastic pellets. After the material strips pass through the cooling water tank, a small amount of moisture will remain on the surface of the material strips. The moisture remaining on the surface of the material strips will follow the material strips into the pelletizer. Excessive moisture inside the pelletizer can easily cause the cutting blades inside the pelletizer to rust, reducing their service life. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 Figure 2 As shown, a plastic granule melting production equipment includes an extruder 1, a cooling water tank 2 is provided on one side of the extruder 1, a pelletizer 3 is provided on one side of the cooling water tank 2, a water removal mechanism 5 is provided between the pelletizer 3 and the cooling water tank 2, and the water removal mechanism 5 includes a mechanism housing 501 arranged on one side of the cooling water tank 2, a water retaining strip 502 is provided at the bottom of the mechanism housing 501, a positioning plate 503 is fixedly installed in the mechanism housing 501, a spring 506 is fixedly installed on the upper end of the mechanism housing 501, and a movable plate 504 is connected to the spring 506. A water-absorbing sponge 505 is fixedly installed on the moving plate 504 and the positioning plate 503. A conveying roller 4 is provided at the front end edge of the mechanism shell 501. A pressing mechanism 6 is provided on the mechanism shell 501. The water removal mechanism 5 can remove moisture on the surface of the material strip to prevent moisture from entering the pelletizer 3 along with the material strip, thereby extending the service life of the pelletizer 3. The pressing mechanism 6 can squeeze out the moisture in the water-absorbing sponge 505, reducing the number of times the water-absorbing sponge 505 is replaced, and the squeezed water will flow back into the cooling water tank 2, thereby reducing the waste of water resources.

[0023] like Figure 3 As shown, a water removal mechanism 5 is provided between the pelletizer 3 and the cooling water tank 2, and the water removal mechanism 5 includes a mechanism shell 501 arranged on one side of the cooling water tank 2, a water retaining bar 502 is provided at the bottom of the mechanism shell 501, a positioning plate 503 is fixedly installed in the mechanism shell 501, a spring 506 is fixedly installed on the upper end of the mechanism shell 501, a movable plate 504 is connected to the spring 506, and a water-absorbing sponge 505 is fixedly installed on both the movable plate 504 and the positioning plate 503, and a pressing notch 507 is opened on the upper surface of the mechanism shell 501.

[0024] Specifically, when the material strip passes through the water removal mechanism 5, the spring 506 will press down the movable plate 504. When pressing down the movable plate 504, it will drive the water-absorbing sponge 505 on the movable plate 504 to move downward, so that the two groups of water-absorbing sponges 505 are attached together. When the solidified material strip passes through the two groups of water-absorbing sponges 505, the moisture on the surface of the material strip can be removed, preventing the moisture from following the material strip into the pelletizer 3, thereby extending the service life of the pelletizer 3.

[0025] like Figure 4 As shown, a conveying roller 4 is provided at the front end edge of the mechanism housing 501, and a pressing mechanism 6 is provided on the mechanism housing 501. The pressing mechanism 6 includes a first positioning frame 605 and a second positioning frame 607 fixed on the mechanism housing 501. A driving shaft 604 is movably mounted on the first positioning frame 605, and a cam 606 is fixedly mounted on the driving shaft 604. The pressing mechanism 6 also includes a reducer 601 connected to the end of the conveying roller 4, and an output shaft 602 is connected to the reducer 601. The ends of the output shaft 602 and the driving shaft 604 are both provided with helical gears 603, and the two sets of helical gears 603 are meshed together.

[0026] Specifically, the conveying roller 4 will drive the input shaft of the reducer 601 to rotate, and the output shaft 602 will rotate slowly after being decelerated by the reducer 601. The slowly rotating output shaft 602 will drive the drive shaft 604 to rotate slowly. After the drive shaft 604 rotates slowly, it will drive the cam 606 to rotate slowly. During the slow rotation of the cam 606, it will enter the mechanism housing 501. The cam 606 entering the mechanism housing 501 will press the movable plate 504 down to the positioning plate 503, thereby squeezing out the moisture in the absorbent sponge 505, reducing the number of times the absorbent sponge 505 is replaced, and the cam 606 enters the mechanism housing 501 in turn, and presses the positioning plate 503 in turn, which can reduce the resistance to the material strip.

[0027] It should be noted that the utility model is a plastic granule melting production equipment. In actual use, the extruder 1 is first used to extrude the material strips. After the extruder 1 extrude the material strips, the material strips can be placed between the conveying rollers 4. After the material strips are placed between the conveying rollers 4, the drive motor 401 can be started. After the drive motor 401 is started, it will drive the conveying rollers 4 to rotate, thereby pulling the material strips to move forward. When the material strips move forward, they will pass through the cooling water trough 2, the dewatering mechanism 5 and the pelletizer 3 in sequence. When the material strips pass through the cooling water trough 2, the moisture inside the material strips will exchange heat with the material strips to solidify the material strips. When the material strips pass through the dewatering mechanism 5, the spring 506 will press down the movable plate 504. When pressing down the movable plate 504, it will drive the water-absorbing sponge 505 on the movable plate 504 to move downward, so that the two groups of water-absorbing sponges 505 are attached together. When the solidified material strips pass through the two groups of absorbent sponges 505, the moisture on the surface of the material strips can be removed. After the moisture is removed, the material strips enter the pelletizer 3 and are cut into plastic particles. During the rotation of the conveying roller 4, it will drive the input shaft of the reducer 601 to rotate. After being decelerated by the reducer 601, the output shaft 602 will rotate slowly. The slowly rotating output shaft 602 will drive the drive shaft 604 to rotate slowly. After the drive shaft 604 rotates slowly, it will drive the cam 606 to rotate slowly. During the slow rotation of the cam 606, it will enter the mechanism housing 501. The cam 606 entering the mechanism housing 501 will press the movable plate 504 down to the positioning plate 503, thereby squeezing out the moisture in the absorbent sponge 505, and the squeezed moisture will flow back to the cooling water tank 2, thereby reducing the waste of water resources.
