Description

Technical Field

[0001] The utility model relates to the technical field of pelletizing, in particular to a thermoplastic elastomer plastic pelletizing device. Background Art

[0002] Thermoplastic elastomer is a type of elastomer that has the elasticity of rubber at room temperature and can be plasticized and formed at high temperature. Its products have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, and at the same time have the characteristics of convenient processing and wide processing methods of ordinary plastics. Thermoplastic elastomer materials have become the latest materials to replace traditional rubber. They are environmentally friendly, non-toxic, comfortable to the touch, and exquisite in appearance, making the products more creative. Therefore, it is also a more humane and high-grade new synthetic material, and a world-standard environmentally friendly material.

[0003] Existing thermoplastic elastomer pelletizing equipment uses different pelletizing methods. Since thermoplastic elastomers are elastic at room temperature, roller pelletizing is not commonly used. Most of the time, a cutter is used to directly cut the elastomer on a flat plate. However, the elastomer is elastic, and the granular elastomers left on the flat plate after the cutter cuts will block the elastomer from moving further, making the elastomer pelletizing uneven and affecting the quality of the finished product. Therefore, it is urgent to improve the existing pelletizing equipment. Utility Model Content

[0030] In one embodiment provided by the present utility model, please refer to Figure 1-7 A thermoplastic elastomer plastic pelletizing device includes a chassis 1, wherein the chassis 1 is provided with a feed port 11 and a discharge port 12, wherein a conveying mechanism is provided in the chassis 1, wherein a driving source 13 for driving the conveying mechanism is installed in the chassis 1, wherein the conveying mechanism conveys the elastomer to a fixed plate 14 in the chassis 1, wherein a cutting plate 15 is rotatably connected to the fixed plate 14, wherein a cutting mechanism is further provided above the cutting plate 15, wherein the cutting mechanism moves toward the fixed plate 14, and the cutting plate 15 is driven to rotate by a second transmission mechanism to cut the elastomer, wherein the cutting mechanism moves away from the fixed plate 14, and the cutting plate 15 rotates, so that the cut granular elastomer falls off the cutting plate 15. A supporting platform for supporting an external elastomer is further provided at the feed port 11.

[0031] By setting up the second transmission mechanism, the material moves along the fixed plate 14 to the cutting plate 15 under the drive of the conveying mechanism. When the cutting mechanism moves toward the elastic body, it drives the second transmission mechanism to move toward the cutting plate 15. The movement of the second transmission mechanism drives the cutting plate 15 to rotate, so that the cutting plate 15 abuts against the elastic body. The cutting mechanism continues to move downward to cut the elastic body on the cutting plate 15. When the cutting mechanism moves away from the elastic body, the second transmission mechanism moves, and the cutting plate 15 is reset under the action of gravity. The granular elastic body cut on the cutting plate 15 flows out of the chassis 1 from the discharge port 12. The utility model realizes automatic unloading of the material after cutting through the second transmission mechanism, and no elastic body remains on the cutting plate 15, so that the equipment can granulate evenly; and the second transmission mechanism drives the cutting plate 15 to rotate, which improves the level of automatic granulation, reduces maintenance work, and further improves production efficiency.

[0033] The driving source 13 is a motor, which drives the driving gear 21 to rotate, and the driving gear 21 rotates to drive the driven gear 22 to rotate, and the driving gear 21 and the driven gear 22 respectively drive the first conveying roller 23 and the second conveying roller 24 to rotate, so as to drive the elastic body to move. In the utility model, the highest point of the feed port 11, the second conveying roller 24 and the fixing plate 14 are on the same plane, so as to ensure the stability of the elastic body transportation process.

[0034] Furthermore, a first transmission mechanism is also provided in the chassis 1, and the conveying mechanism drives the cutting mechanism to move through the first transmission mechanism. The setting of the first transmission mechanism enables the conveying mechanism and the cutting mechanism to be linked, so that the cutting mechanism can automatically cut the elastomer during the conveying mechanism transports the elastomer, further improving the automation level of the equipment and improving production efficiency.

[0035] Furthermore, the chassis 1 is also provided with a first transmission mechanism, the first transmission mechanism includes a first pulley 51 fixedly connected to the output shaft of the driving source 13, the chassis 1 is also rotatably provided with a second pulley 52, the first pulley 51 and the second pulley 52 are connected through a conveyor belt 53, the second pulley 52 is connected to a lifting mechanism, and the lifting mechanism is connected to a cutting mechanism. The lifting mechanism includes a limit rod 61 fixedly connected to the second belt path, the chassis 1 is also fixedly provided with a guide rod 62, a lifting rod 63 is slidably connected in the guide rod 62, a limit groove 64 adapted to the limit rod 61 is provided on the lifting rod 63, the limit groove 64 is horizontally arranged, the lifting rod 63 is connected to the cutting mechanism, the limit rod 61 rotates with the second pulley 52, and drives the lifting rod 63 to slide along the guide rod 62 through the limit groove 64. The guide rod 62 is used to constrain the moving direction of the lifting rod 63. In this embodiment, the lifting rod 63 moves in the vertical direction.

[0036] The motor rotates through the first pulley 51 and the conveyor belt 53 to drive the second pulley 52 to rotate. The rotation of the second pulley 52 drives the limiting rod 61 to rotate. The second limiting rod 61 rotates through the horizontal limiting groove 64 to drive the lifting rod 63 to move up and down. The lifting rod 63 moves up and down to drive the cutting mechanism to move up and down.

[0037] Furthermore, the cutting mechanism includes a horizontal block 31 fixedly connected to the lifting rod 63, a longitudinal knife 32 and a plurality of transverse knives 33 are fixedly connected to the side of the horizontal block 31 close to the cutting plate 15, one end of each transverse knife 33 abuts against the side wall of the longitudinal knife 32, and the horizontal block 31 is connected to a second transmission mechanism. The second transmission mechanism includes a first transmission rod 41 slidably connected to the sliding groove in the horizontal block 31, a spring 42 is fixedly arranged between the end of the first transmission rod 41 and the side wall of the sliding groove, a second transmission rod 43 is arranged on the rotating shaft of the cutting plate 15, and a baffle 44 is also arranged in the chassis 1, the lower section of the baffle 44 is in the same plane as the upper end surface of the fixed plate 14, the horizontal block 31 moves downward to drive the first transmission rod 41 to abut against the second transmission rod 43, and the second transmission rod 43 moves to drive the cutting plate 15 to rotate until it abuts against the baffle 44. The spring 42 is used for buffering. When the cutting plate 15 completes the rotation and the longitudinal knife 32 and the transverse knife 33 cut the elastomer driven by the horizontal block 31, the spring 42 is compressed to prevent the first transmission rod 41 from continuing to move, causing the cutting plate 15 to damage the baffle 44 and continue to rotate, resulting in equipment failure.

[0038] The movement of the lifting rod 63 drives the horizontal block 31 to move, and the movement of the horizontal block 31 drives the first transmission rod 41 to move through the spring 42. The first transmission rod 41 moves and abuts against the second transmission rod 43 and drives the second transmission rod 43 to rotate. The rotation of the second transmission rod 43 drives the cutting plate 15 to rotate until the cutting plate 15 abuts against the baffle 44, and the cutting plate 15 is flush with the fixed plate 14. The cutting plate 15 supports the elastomer, and the horizontal block 31 continues to move to drive the longitudinal knife 32 and each transverse knife 33 to cut the elastomer. After cutting is completed, the horizontal block 31 drives the first transmission rod 41 to move upward, and the cutting plate 15 is reset under the action of gravity. The granular elastomer cut on the cutting plate 15 flows out of the chassis 1 from the discharge port 12.

[0039] Furthermore, the cutting plate 15 is provided with a groove 16, and the position of the groove 16 corresponds to the position of the longitudinal knife 32 and each transverse knife 33. In order to avoid incomplete cutting and the elastomer particles after cutting still sticking together, the groove 16 is provided on the cutting plate 15 to facilitate complete cutting.

[0040] Working principle: The elastic body enters from the feed port 11 and moves along the fixed plate 14 through the middle part of the first conveyor roller 23 and the second conveyor roller 24. The motor rotates through the first pulley 51 and the conveyor belt 53 to drive the second pulley 52 to rotate. The second pulley 52 rotates to drive the limit rod 61 to rotate. The second limit rod 61 rotates through the horizontal limit groove 64 to drive the lifting rod 63 to move up and down. The lifting rod 63 moves to drive the horizontal block 31 to move. The horizontal block 31 moves to drive the first transmission rod 41 to move through the spring 42. The first transmission rod 41 moves. The second transmission rod 43 is rotated to drive the cutting plate 15 to rotate until the cutting plate 15 is in contact with the baffle plate 44, and the cutting plate 15 is flush with the fixed plate 14. The cutting plate 15 supports the elastomer, and the horizontal block 31 continues to move to drive the longitudinal knife 32 and each transverse knife 33 to cut the elastomer. After the cutting is completed, the horizontal block 31 drives the first transmission rod 41 to move upward, and the cutting plate 15 is reset under the action of gravity. The granular elastomer cut on the cutting plate 15 flows out of the chassis 1 from the discharge port 12.

[0041] By setting up the second transmission mechanism, the material moves along the fixed plate 14 to the cutting plate 15 under the drive of the conveying mechanism. When the cutting mechanism moves toward the elastic body, it drives the second transmission mechanism to move toward the cutting plate 15. The movement of the second transmission mechanism drives the cutting plate 15 to rotate, so that the cutting plate 15 abuts against the elastic body. The cutting mechanism continues to move downward to cut the elastic body on the cutting plate 15. When the cutting mechanism moves away from the elastic body, the second transmission mechanism moves, and the cutting plate 15 is reset under the action of gravity. The granular elastic body cut on the cutting plate 15 flows out of the chassis 1 from the discharge port 12. The utility model realizes automatic unloading of the material after cutting through the second transmission mechanism, and no elastic body remains on the cutting plate 15, so that the equipment can granulate evenly; and the second transmission mechanism drives the cutting plate 15 to rotate, which improves the level of automatic granulation, reduces maintenance work, and further improves production efficiency.
