Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to a high-efficiency granulator for recycled polyester chips. Background Technology

[0002] Polyester chips are white granular solids polymerized from purified terephthalic acid and ethylene glycol, scientifically known as polyethylene terephthalate. Polyester chips are mainly used for fiber-grade, bottle-grade, and film-grade polyester chips. Fiber-grade polyester chips are used to manufacture polyester staple fibers and polyester filaments, serving as raw materials for polyester fiber companies to process fibers and related products. Bottle-grade polyester chips are widely used in the packaging of various beverages, especially carbonated beverages. Film-grade polyester chips are mainly used in packaging materials, films, and magnetic tapes. Traditional recycled polyester chip granulation produces particles of different sizes, requiring filtration and screening after production, resulting in low efficiency. To improve this situation, a high-efficiency recycled polyester chip granulator is proposed.

[0003] As disclosed in the patent announcement number CN221316955U, a polyester chipping device includes a discharge box, a tray at the front end of the discharge box, a support on the front side of the tray, a discharge pipe connected to the discharge box on the support, and a rotatable first worm gear at the front end of the discharge box. When the first worm gear rotates, it can form a structure in which the tray moves back and forth left and right and the support swings back and forth. The lower end of the support is provided with a plurality of hooks that can move inward or outward simultaneously.

[0004] Although it enables the discharge port to move evenly, thereby allowing polyester chips to be evenly loaded into the box and further improving work efficiency, it does not solve the problem that existing pelletizers are not conducive to convenient reciprocating oscillation cutting and granulation, and screening of particles of different diameters, and are not conducive to screening and classifying recycled polyester chip particles, thus affecting the convenience of pelleting and screening. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency granulator for recycled polyester chips, which solves the problem mentioned in the background art that the granulator is not convenient for reciprocating oscillation cutting and granulation and screening of particles of different diameters, which is not conducive to screening and classifying the particles of recycled polyester chips and affects the convenience of granulation and screening of particles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency granulator for recycled polyester chips, comprising a housing and a support frame. The support frame is installed on the outer wall of one side of the housing, and an integrated box is installed on the outer wall of the housing above the support frame. A material pipe is installed at the center of the interior of the housing, and a material box is installed at the top of the housing, extending into the interior of the material pipe. A spiral blade is movably installed inside the material pipe, and a stepper motor is installed on the outer wall of the other side of the housing.

[0007] Preferably, the output end of the stepper motor is connected to the spiral blade, and multiple sets of heating mechanisms with equal spacing are installed on the outer wall of the material tube.

[0011] Preferably, a linkage arm is provided at the end of the linkage rod away from the worm gear, and a left movable shaft is provided at the end of the linkage arm near the linkage rod, and the linkage arm is movably connected to the linkage rod through the left movable shaft.

[0012] Preferably, a hinge shaft is fixedly installed at the end of the linkage arm away from the linkage rod, and the hinge shaft is movably connected to the integrated box. A cutter is installed at the end of the hinge shaft away from the integrated box.

[0013] Preferably, a lower screen is slidably mounted on the top of the support frame, and an upper screen is mounted on the top of the lower screen.

[0014] Preferably, a drive motor is installed on the side wall of the support frame, a drive rod is installed at the output end of the drive motor, and a rotating disk is installed at the end of the drive rod away from the drive motor.

[0015] Preferably, a reciprocating rod is movably installed at an eccentric position on the side wall of the rotating disk, and the reciprocating rod is movably connected to the lower screen.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this granulator not only realizes convenient reciprocating oscillating cutting and granulation and screening of particles of different diameters, facilitating the screening and classification of recycled polyester chip particles, but also improves the convenience of granulation and screening of particles.

[0017] (1) The spiral blade is driven by a stepper motor to rotate, and the raw material is moved by the spiral blade. During the movement of the raw material inside the material tube, the heating mechanism heats the material tube to melt the recycled polyester chips. Under the continuous action of the spiral blade, the melted recycled polyester chips are moved by the spiral blade and extruded from inside the spiral blade. After extrusion, the recycled polyester chips solidify into strips. The servo motor drives the worm to rotate, and the worm drives the worm wheel to rotate. The worm wheel drives the connecting rod to swing back and forth through the right movable shaft. The connecting rod drives the linkage arm to swing back and forth through the left movable shaft. The linkage arm drives the hinge shaft and the cutter to swing back and forth. The cutter swings back and forth to cut the strip-shaped recycled polyester chips into pellets, thereby completing the pelleting of recycled polyester chips. Convenient reciprocating swing cutting pelleting is realized, which improves the convenience of pelleting.

[0018] (2) The drive motor drives the rotating disk to rotate through the drive rod, the rotating disk drives the reciprocating rod to swing back and forth, the reciprocating rod drives the lower screen to slide back and forth on the surface of the support frame, and the lower screen drives the upper screen to swing back and forth. Particles smaller than the holes on the surface of the upper screen fall to the surface of the lower screen and are discharged from the surface of the lower screen, while particles larger than the holes on the surface of the upper screen pass through the upper screen and are discharged. This allows for the classification and discharge of particles of different diameters, reducing the time for subsequent particle classification and screening. It realizes the screening of particles of different diameters by reciprocating shaking, which facilitates the screening and classification of recycled polyester chips and improves the convenience of screening and classification.

[0028] Example 1

[0029] Please see Figure 1-5 An embodiment of this utility model provides: a high-efficiency granulator for recycled polyester chips, including a housing 1 and a support frame 2. The support frame 2 is installed on the outer wall of one side of the housing 1. An integrated box 8 is installed on the outer wall of the housing 1 above the support frame 2.

A spiral blade 6 is movably installed inside the material pipe 5. A stepper motor 4 is installed on the outer wall of the other side of the housing 1. The stepper motor 4 serves as a power drive and its output end is connected to the spiral blade 6. Multiple sets of heating mechanisms 7 with equal spacing are installed on the outer wall of the material pipe 5.

[0030] Recycled polyester chips are poured into the feed hopper 3. The chips then enter the feed tube 5. The stepper motor 4 is turned on, driving the spiral blades 6 to rotate. The spiral blades 6 move the raw material within the feed tube 5. During this movement, the heating mechanism 7 heats the feed tube 5, melting the recycled polyester chips. Under the continuous action of the spiral blades 6, the melted chips are moved and extruded from the spiral blades 6. After extrusion, the recycled polyester chips solidify into strips. At this point, the servo motor 9 is activated. The servo motor 9 drives the worm gear 10 to rotate. Under the mutual meshing of the worm gear 10 and the worm wheel 11, the worm gear 10 drives the worm wheel 11 to rotate. The worm wheel 11 drives the connecting rod 13 to swing back and forth through the right movable shaft 12. The connecting rod 13 drives the linkage arm 15 to swing back and forth through the left movable shaft 14. The linkage arm 15 drives the hinge shaft 16 and the cutter 17 to swing back and forth. The cutter 17 swings back and forth to cut the strip-shaped recycled polyester chips into pellets, thereby completing the pelleting of recycled polyester chips. This achieves convenient reciprocating swing cutting and pelleting, improving the convenience of pelleting.

[0031] A servo motor 9 is installed on the outer wall of the integrated box 8. The servo motor 9 serves as a power drive. A worm gear 10 is installed at the output end of the servo motor 9. A worm wheel 11 is movably installed inside the integrated box 8 on one side of the worm gear 10, and the worm wheel 11 meshes with the worm gear 10.

[0032] A connecting rod 13 is provided on the side wall of the worm gear 11. A right movable shaft 12 is provided at one end of the connecting rod 13 near the worm gear 11, and the connecting rod 13 is movably connected to the worm gear 11 through the right movable shaft 12.

[0033] A linkage arm 15 is provided at the end of the linkage rod 13 away from the worm gear 11. A left movable shaft 14 is provided at the end of the linkage arm 15 close to the linkage rod 13, and the linkage arm 15 is movably connected to the linkage rod 13 through the left movable shaft 14. A hinge shaft 16 is fixedly installed at the end of the linkage arm 15 away from the linkage rod 13, and the hinge shaft 16 is movably connected to the integrated box 8. A cutter 17 is installed at the end of the hinge shaft 16 away from the integrated box 8.

[0034] A lower screen 23 is slidably installed on the top of the support frame 2, and an upper screen 22 is installed on the top of the lower screen 23. A drive motor 18 is installed on the side wall of the support frame 2. The drive motor 18 plays the role of power drive. A drive rod 19 is installed at the output end of the drive motor 18. A rotating disk 20 is installed at the end of the drive rod 19 away from the drive motor 18.

[0035] A reciprocating rod 21 is movably installed at an eccentric position on the side wall of the rotating disk 20, and the reciprocating rod 21 is movably connected to the lower screen 23;

[0036] After pelleting, the recycled polyester chips fall onto the surface of the upper screen 22. The drive motor 18 is turned on, and the drive motor 18 drives the rotating disk 20 to rotate via the drive rod 19. The rotating disk 20 drives the reciprocating rod 21 to swing back and forth. With the sliding cooperation between the lower screen 23 and the support frame 2, the reciprocating rod 21 drives the lower screen 23 to slide back and forth on the surface of the support frame 2. The lower screen 23 drives the upper screen 22 to swing back and forth. Particles smaller than the holes on the surface of the upper screen 22 fall onto the surface of the lower screen 23 and are discharged from the surface of the lower screen 23, while particles larger than the holes on the surface of the upper screen 22 pass through the upper screen 22 and are discharged. This process classifies and sorts particles of different diameters, reducing the time required for subsequent particle sorting. It achieves the reciprocating shaking screening of particles of different diameters, facilitating the sorting and classification of recycled polyester chips and improving the convenience of sorting.

[0037] Work steps

[0038] Recycled polyester chips are poured into the feed hopper 3. The chips then enter the feed tube 5. A stepper motor 4 drives a spiral blade 6 to rotate, which in turn moves the chips. During this movement, a heating mechanism 7 heats the feed tube 5, melting the recycled polyester chips. Under the continuous action of the spiral blade 6, the melted chips are moved and extruded from the spiral blade 6. After extrusion, the chips solidify into strips. A servo motor 9 drives a worm gear 10 to rotate, which in turn drives a worm wheel 11. The worm wheel 11, via a right movable shaft 12, drives a connecting rod 13 to oscillate reciprocally. The connecting rod 13, via a left movable shaft 14, drives a linkage arm 15 to oscillate reciprocally. The linkage arm 15, in turn, drives a hinge shaft 16 and a cutter 17 to oscillate reciprocally. The cutter 17 cuts the strips... The recycled polyester chips are granulated by reciprocating oscillation. After granulation, the recycled polyester chips fall onto the surface of the upper screen 22. The drive motor 18 drives the rotating disk 20 to rotate through the drive rod 19. The rotating disk 20 drives the reciprocating rod 21 to oscillate back and forth. With the sliding cooperation between the lower screen 23 and the support frame 2, the reciprocating rod 21 drives the lower screen 23 to slide back and forth on the surface of the support frame 2. The lower screen 23 drives the upper screen 22 to oscillate back and forth. Particles smaller than the holes on the surface of the upper screen 22 fall onto the surface of the lower screen 23 and are discharged from the surface of the lower screen 23. Particles larger than the holes on the surface of the upper screen 22 pass through the upper screen 22 and are discharged. This process classifies and screens particles of different diameters, reducing the time spent on subsequent particle classification. The above is the complete usage of the high-efficiency recycled polyester chip granulator.
