Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, specifically a soft material pelletizer for plastic particle processing. Background Technology

[0002] A soft plastic pelletizer is specifically designed for the pelletizing process of soft plastics. It mainly consists of a feeding device, a cutting mechanism, a transmission system, and a control system. The feeding device smoothly conveys the soft plastic raw material to the cutting area, ensuring uniform feeding. The cutting mechanism is the core component; sharp blades, rotating at high speed, precisely cut the soft material into uniform pellets. The transmission system provides power to the cutting blades, ensuring the stability and continuity of the cutting action. The control system can flexibly adjust parameters such as pelletizing speed and length to meet different production needs. This pelletizer is optimized for the characteristics of soft materials, effectively avoiding problems such as adhesion and deformation during cutting. The produced plastic pellets are regular in shape and reliable in quality, laying a good foundation for subsequent plastic processing.

[0003] A search revealed that Chinese patent CN221697811U discloses a soft material pelletizer for processing plastic particles. The patent describes a method for extruding plastic particles by setting an extrusion mechanism. After the plastic particles are extruded, a blower mechanism can blow the linear plastic particles up, thereby preventing the sticky linear plastic particles from contacting the blower mechanism. The blowing mechanism also allows the formed linear plastic particles to dry quickly. Subsequently, a drive mechanism can be used to drive the cutting mechanism to rotate quickly, thus enabling the extruded linear plastic particles to be cut quickly.

[0004] In this solution, although the soft plastic material can be dried before cutting, there will be residues adhering to the extrusion plate when the plastic passes through it. The device is difficult to clean and requires the use of a screwdriver to disassemble, which is time-consuming and laborious, resulting in a significant reduction in work efficiency. In order to solve this technical problem, this utility model proposes a soft material pelletizer for plastic particle processing. Utility Model Content

The device is difficult to clean and requires the use of a screwdriver to disassemble, which is time-consuming and laborious, resulting in a significant reduction in work efficiency. In order to solve this technical problem, this utility model proposes a soft material pelletizer for plastic particle processing.

[0013] Preferably, a cooling pool is provided inside one end of the workbench, and a retrieval net is provided inside the cooling pool.

[0014] (III) Beneficial Effects

[0015] This utility model provides a soft material pelletizer for processing plastic particles. It has the following beneficial effects:

[0016] (1) The connecting ring is limited in the groove by a slider to ensure the smooth rotation of the cutting blade. The extrusion plate is used to extrude soft material into a cylindrical shape, and it is limited in the slot by a retaining ring. The pin passes through the inner hole of the retaining ring and is connected to the limiting ring. The spring provides the restoring force. When it is necessary to disassemble the extrusion plate, pull the limiting ring, the pin disengages from the inner hole of the retaining ring, and the extrusion plate can be pulled out along the slot. The positioning rod is used to fix the position of the connecting ring. Pull out the positioning rod, and the connecting ring can slide in the groove by the slider to realize the disassembly of the cutting blade. The cooperation of these components solves the problem of inconvenient maintenance of the cutting blade and extrusion plate in the existing device. Traditional devices are time-consuming and laborious to disassemble and replace parts due to their complex structure. This design realizes the quick disassembly and assembly of the cutting blade and extrusion plate through a clever connection and limiting structure, which facilitates cleaning, maintenance and replacement, greatly improves work efficiency and ensures the efficient operation of soft material pelletizing.

[0017] (2) In the soft material pelletizing operation, the workbench provides support for the entire device. The motor is installed on the workbench. After starting, it drives the rotating rod to rotate inside the feeding hopper. The auger blade on the rotating rod rotates accordingly, squeezing and pushing the soft plastic fed into the feeding hopper through the valve towards the end of the hopper. The soft plastic is squeezed to the extrusion plate and flows out in a cylindrical shape. The rotating rod drives the connecting column to rotate, and the connecting column causes the cutting blade to rotate synchronously, cutting the extruded soft plastic. The cut particles fall into the retrieval net in the cooling pool below. The cooling water in the cooling pool quickly cools the plastic particles, making it easy to retrieve and collect them through the retrieval net. The combination of this set of components solves the problems of low soft material pelletizing efficiency and inconvenient cooling and collection in existing devices. Traditional devices may have poor connection between feeding and cutting, resulting in low pelletizing efficiency and cumbersome cooling and collection methods. This design, through the collaboration of various components, achieves efficient feeding, precise cutting, and rapid cooling and collection of soft materials, improving the overall efficiency of soft material pelletizing and optimizing the production process.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A soft material pelletizer for processing plastic particles includes a worktable 1, a motor 2 fixedly connected to the top of the worktable 1, a rotating rod 3 fixedly connected to the output end of the motor 2, a feeding hopper 4 on the top of the worktable 1, a connecting post 5 fixedly connected to the end of the rotating rod 3, a sliding groove 6 inside the connecting post 5, a connecting ring 7 slidably connected to the outside of the connecting post 5, a plurality of sliders 9 fixedly connected to the inner wall of the connecting ring 7, and the sliders 9 slidably connected within the sliding groove 6, while a cutting blade 8 is fixedly connected to the outside of the connecting ring 7. The connecting ring 7 is fixedly connected to the connecting post 5 via a positioning rod 16. The end of the feed hopper 4 has a slot 15. The end of the rotating rod 3 is slidably connected to the extrusion plate 11. The outer wall of the extrusion plate 11 is fixedly connected to the retaining ring 12, which is inserted into the slot 15. The connecting ring 7 has an inner hole 10. The positioning rod 16 passes through the connecting post 5 and extends to the outside of the connecting ring 7. Multiple springs 14 are fixedly connected to the outer wall of the feed hopper 4. The other end of the spring 14 is fixedly connected to the limiting ring 17. The limiting ring 17 is fixedly connected to the pin 13, and the spring 14 is sleeved on the outer wall of the pin 13. At the same time, the pin 13 passes through the feed hopper 4 and extends into the retaining ring 12.

[0026] Because the extrusion plate 11 and the cutting blade 8 are prone to clogging or damage after prolonged use, convenient maintenance and replacement are required. When encountering such problems, first pull out the positioning rod 16, then pull the connecting ring 7 outwards. Since the connecting ring 7 is limited within the slide groove 6 by the slider 9, the cutting blade 8 can be directly removed and replaced while pulling. To remove the extrusion plate 11, pull the limiting ring 17 outwards. This will cause the limiting ring to move the pin 13 upwards, disengaging it from the inner hole of the retaining ring 12. At this time, the spring 14 will be in a stretched state. Next, pull the extrusion plate 11 outwards. Since the extrusion plate is limited within the slot 15 by the retaining ring 12, it can slide outwards along the slot, thus achieving disassembly for cleaning or replacement. For installation, simply reverse the above steps. Through the close cooperation between these components, the quick disassembly and installation of the cutting blade and the extrusion plate are achieved, effectively improving work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, a auger blade 18 is fixedly connected to the outer wall of the rotating rod 3, and both the auger blade 18 and the rotating rod 3 are rotatably connected inside the feeding barrel 4. A feeding hopper 19 is provided on the top of the feeding barrel 4, and a valve 20 is provided outside the feeding hopper 19. A housing 21 is fixedly connected to the top of the workbench 1, and the housing 21 is located outside the motor 2. A cooling pool 22 is provided inside one end of the workbench 1, and a retrieval net 23 is provided inside the cooling pool 22.

[0028] When processing soft plastic into pellets, the operator first opens valve 20 and then feeds the soft plastic into feeding hopper 4 via hopper 19. Motor 2 is then started, causing rotating rod 3 to rotate. During rotation, the auger blades 18 on the rotating rod continuously push the plastic from the hopper towards the end of the feeding hopper. Under continuous compression, the plastic flows out from extrusion plate 11, forming a cylindrical shape. The rotation of rotating rod 3 drives connecting column 5 to rotate, which in turn drives the cutting blade 8 on connecting ring 7 to rotate. The rotating cutting blade cuts the soft plastic flowing from the extrusion plate into pellets, which then fall into retrieval net 23 within cooling tank 22. The cooling water in cooling tank 22 rapidly cools the plastic pellets, which can then be retrieved using retrieval net 23.

[0029] Working principle: When the worker cuts the soft material into pellets, valve 20 is opened, and the soft plastic is fed into the feeding bucket 4 through the feed hopper 19. Motor 2 is then started, driving the rotating rod 3 to rotate. As the rotating rod 3 rotates, the plastic is conveyed to the end via the auger blade 18. Through continuous compression, the plastic flows out through the extrusion plate 11 and forms a cylindrical shape. The rotation of the rotating rod 3 also drives the connecting column 5 to rotate, which in turn drives the cutting blade 8 on the connecting ring 7 to rotate. The cutting blade 8 cuts the soft plastic into pellets, which fall into the retrieval net 23 in the cooling pool 22. The pellets are then rapidly cooled by the cooling water in the cooling pool 22 and pass through the retrieval net 23. After retrieving the extrusion plate 11 and the cutting blade 8, it is found that prolonged use can lead to blockages and damage. In this case, the positioning rod 16 is pulled out, and the connecting ring 7 is pulled outward. The connecting ring 7 is limited in the slide groove 6 by the slider 9. At this point, the cutting blade 8 can be directly disassembled and replaced. Pulling the limiting ring 17 outward will cause the pin 13 to move upward and disengage from the inner hole of the retaining ring 12. At this time, the spring 14 is in a stretched state, which pulls the extrusion plate 11 outward. The extrusion plate 11 is limited in the slot 15 by the retaining ring 12 and slides outward, thereby achieving the effect of disassembly, cleaning and replacement. During installation, the above steps are reversed. Through their cooperation, the effect of quick disassembly and quick installation is achieved, which improves work efficiency.
