Description

TECHNICAL FIELD

[0002] TPE material, full name Thermoplastic Elastomer, is a kind of material with the characteristics of high elasticity, high strength and high resilience of rubber, and injection molding. In the production process of TPE material, the finished TPE material is pulled into a long strip, cooled in water, and then sent to the granulating equipment. The TPE strip material is cut into particles by the blade of the granulating equipment, and finally weighed and packaged.

[0003] In the traditional TPE granulating equipment, there are significant defects in the feeding link. If a single feeding method is used, the granulating efficiency is low, which is difficult to meet the needs of large-scale production. In order to improve the efficiency, if a large bundle or tight code arrangement of multiple TPE materials is gathered for granulating, due to the lack of effective constraint and separation between the strip materials, they interfere with each other during the granulating process, and it is easy to appear disorder. This disorder not only leads to uneven granulation, affecting product quality, but also may cause uneven stress of the cutting knife during cutting, thereby causing wear and even damage of the cutting knife, increasing the maintenance cost and downtime of the equipment, and seriously affecting the production efficiency and economic benefits.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] In combination with the drawings Figure 1 to the drawings Figure 7A pelletizing device for TPE production includes a workbench 1. A U-shaped frame 2 is fixedly mounted on the left side of the upper end face of the workbench 1. A cutter 3 is slidably mounted inside the U-shaped frame 2. A drive assembly for driving the cutter 3 to reciprocate up and down is fixedly mounted on the U-shaped frame 2. A discharge port 17 is provided on the right side of the upper end face of the workbench 1. A groove 4 is provided on the right side of the upper end face of the workbench 1. Several horizontally arranged rotating shafts 5 are rotatably mounted inside the groove 4. Multiple grooved wheels 6 are fixedly mounted on each rotating shaft 5. Vertical plates 7 are fixed on both sides of the groove 4 on the upper end face of the workbench 1. A rotating shaft 8 is rotatably mounted between two opposing vertical plates 7. Multiple grooved wheels 9 are fixedly mounted on each rotating shaft 8. The grooved wheels 9 are located directly above the grooved wheels 6, and the two together form a channel for long strip-shaped TPE material to pass through. A motor 10 for driving the rotating shaft 8 on the rightmost vertical plate 7 is fixedly mounted on the outside of the rightmost vertical plate 7.

[0028] The U-shaped frame 2 has slide rails 11 fixedly installed on both inner side walls, and sliders 12 that are matched and slidably connected to the slide rails 11 are fixedly installed on both sides of the cutter 3. The driving assembly includes a second motor 13 fixedly installed on the upper end of the U-shaped frame 2, a drive disk 14 fixedly installed on the drive shaft of the second motor 13, a connecting rod 15 hinged to the upper end of the cutter 3, and the other end of the connecting rod 15 hinged to the side of the drive disk 14 near the edge. The U-shaped frame 2 has a through hole 16 for the connecting rod 15 to pass through.

[0029] The working principle of this TPE pelletizing device is as follows: The device uses a motor 10 to drive a rotating shaft 8, which in turn rotates a grooved wheel 9. The channel formed between the grooved wheel 9 and the grooved wheel 6 clamps and conveys the elongated TPE material. Simultaneously, a motor 13 drives a drive disc 14 to rotate. A connecting rod 15 converts the circular motion of the drive disc 14 into the reciprocating motion of a cutter 3 along a slide rail 11, thereby pelletizing the conveyed TPE elongated material. Both the grooved wheel 9 and the grooved wheel 6 are made of rubber.

[0030] The working process of the pelletizing equipment for TPE production according to this utility model is as follows:

[0031] 1. Feeding preparation: Place the water-cooled long strip of TPE material between the two upright plates 7 on both sides of the groove 4 on the workbench 1, so that the TPE material passes through the channel formed between the groove wheel 6 and the groove wheel 9.

[0032] 2. Feeding Start: Turn on motor 10. Motor 10 drives the rotating shaft 8 located on the outer side of the rightmost vertical plate 7 to rotate, which in turn drives the grooved wheel 9 on the rotating shaft 8 to rotate. Through interaction with the grooved wheel 6, the long strip of TPE material is stably clamped and conveyed, so that the TPE material moves at a uniform speed towards the cutter 3.

[0033] 3. Cutter driving: start motor 2 13, the driving shaft of motor 2 13 drives the circumferential motion of driving disc 14. Since one end of connecting rod 15 is hinged to the upper end of cutter 3, the other end is hinged to the side near the edge of driving disc 14, and U-shaped frame 2 is provided with through hole 16 for connecting rod 15 to pass through, the circumferential motion of driving disc 14 is converted into the up-down reciprocating motion of cutter 3 along the slide rail 11 on the inner side wall of U-shaped frame 2 through connecting rod 15. The slider 12 on both sides of the cutter 3 slides on the slide rail 11, ensuring the stability of the movement of the cutter 3.

[0034] 4. Granulating operation: in the process of continuously conveying TPE long strip material to the lower side of cutter 3, the up-down reciprocating cutter 3 cuts it into particles. The cut particles are discharged from the discharge port 17 on the right side of the upper end face of the workbench 1 and collected.

[0035] The above describes the utility model and its implementation, which is not limited. The drawings show only one embodiment of the utility model, and the actual structure is not limited. In summary, if a person skilled in the art is inspired, without departing from the spirit of the utility model, without creative design, similar structure and embodiments of the technical solution should belong to the protection scope of the utility model.
