Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and in particular to a thermoforming device with waste recycling function. Background Technology

[0002] A vacuum forming machine, also known as a thermoforming machine, is a machine that uses heated and plasticized thermoplastic plastic rolls such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging boxes, frames, and other products. It utilizes the vacuum suction generated by a vacuum pump to mold heated and softened thermoplastic plastic sheets such as PVC and PET into various shapes of vacuum covers, blister trays, and other packaging materials.

[0003] The current method for recycling waste from vacuum forming machines involves using a roll to collect the cut scraps. This method often has the following problems: as the waste is continuously rolled up, the volume of the roll gradually expands. As the rolling process continues, the roll needs to be replaced manually, which requires stopping the machine for replacement and thus affects the vacuum forming efficiency. Furthermore, when processing the waste later, the rolled-up waste needs to be unrolled, which also affects the waste processing efficiency.

The drive motor is started to drive one rotating shaft to rotate. The rotation of one rotating shaft drives another rotating shaft to rotate in the opposite direction under the action of two toothed discs, thereby driving two crushing rollers to move towards the middle at the same time, realizing the purpose of automatically crushing the strip-shaped waste entering the crushing box. The crushed waste can be discharged under the action of the guide plate and the discharge frame, thus enabling the blister packaging equipment to achieve the purpose of automatically crushing the strip-shaped waste, which facilitates the subsequent processing of powder and effectively improves the blister packaging efficiency and the subsequent waste processing efficiency.

The rotation of the drive wheel, under the action of the first transmission belt, drives the driven wheel and the connecting rod to rotate. The rotation of the connecting rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear and the reciprocating threaded column to rotate. The rotation of the reciprocating threaded column drives the rectangular plate to move back and forth, thereby driving the cutter to move back and forth, so as to achieve the purpose of continuous reciprocating cutting of the strip of waste material entering the crushing box, avoiding the biting force of the two crushing rollers from pulling the strip of waste material during transportation, thereby ensuring the accuracy of thermoforming.

[0027] 3. The blister packaging equipment with waste recycling function described in this application, through the setting of a circulation mechanism, allows the waste material crushed by two crushing rollers to be filtered by a filter screen, so that waste material of the appropriate particle size falls to the guide plate and is discharged, while larger waste material can pass through the filter screen and enter the connecting box. Furthermore, when the cutter continuously cuts the strip-shaped waste material entering the crushing box, the rotation of the reciprocating threaded column and the second bevel gear can drive the rotation of the third bevel gear and the vertical shaft. The rotation of the vertical shaft, under the action of the two transmission wheels and the second transmission belt, drives the conveyor shaft to rotate. The rotation of the conveyor shaft drives the spiral conveyor blade to rotate in the conveyor cylinder, conveying the large waste material in the connecting box upwards and discharging it through the discharge pipe to the top of the two crushing rollers for re-circulation and crushing. This effectively ensures that the particle size of the waste material discharged after crushing is consistent, further improving the efficiency of subsequent waste material processing.

[0033] Specifically, the drive motor 304 can drive a rotating shaft 302 to rotate.

The drive motor 304 is started to drive one rotating shaft 302 to rotate. The rotation of one rotating shaft 302 drives another rotating shaft 302 to rotate in the opposite direction under the action of two toothed discs 305, thereby driving two crushing rollers 303 to move towards the middle at the same time, so as to achieve the purpose of automatically crushing the strip-shaped waste entering the crushing box 301. The crushed waste can be discharged under the action of the guide plate 306 and the discharge frame 307, thus enabling the thermoforming equipment to achieve the purpose of automatically crushing the strip-shaped waste, which facilitates the subsequent processing of powder and effectively improves the thermoforming efficiency and the subsequent waste processing efficiency.

[0045] In this invention, a cutting mechanism 400 is provided. When the strip-shaped waste material enters the crushing box 301 and is crushed by the two crushing rollers 303, the rotation of the rotating shaft 302 drives the drive wheel 408 to rotate. The rotation of the drive wheel 408, under the action of the first transmission belt 409, drives the driven wheel 407 and the connecting rod 4010 to rotate. The rotation of the connecting rod 4010 drives the first bevel gear 405 to rotate. The rotation of the first bevel gear 405 drives the second bevel gear 406 and the reciprocating threaded column 402 to rotate. The rotation of the reciprocating threaded column 402 drives the rectangular plate 403 to move back and forth, thereby driving the cutter 404 to move back and forth. This achieves the purpose of continuously and reciprocally cutting the strip-shaped waste material entering the crushing box 301, avoiding the biting force of the two crushing rollers 303 from pulling the strip-shaped waste material during transportation, thus ensuring the accuracy of the vacuum forming process.

[0046] Please refer to this carefully. Figure 8 , Figure 9 The side of the crushing box 301 is provided with a circulation mechanism 500. The circulation mechanism 500 includes a connecting box 501 fixed on the side of the crushing box 301 and a conveying cylinder 502 fixed on the upper surface of the connecting box 501.

The side of the connecting box 501 and the crushing box 301 is provided with a fan-shaped opening extending into the interior of the crushing box 301. The inner wall of the crushing box 301 is provided with a filter screen plate 503 corresponding to the fan-shaped opening. The filter screen plate 503 is inclinedly arranged on the inner wall of the crushing box 301. The bottom end of the conveying cylinder 502 is provided with an arc-shaped opening corresponding to the fan-shaped opening.

[0047] Specifically, the filter screen 503 can intercept large particles of waste and guide them into the connecting box 501.

[0048] Please refer to this carefully. Figure 8 , Figure 9The inner top wall of the conveying cylinder 502 is rotatably provided with a conveying shaft 504. The outer surface of the conveying shaft 504 is fixed with a spiral conveying blade 505 adapted to the inner wall of the conveying cylinder 502. The top outer surface of the conveying cylinder 502 is inclinedly provided with a feeding pipe 506. One end of the feeding pipe 506 extends into the interior of the conveying cylinder 502, and the other end of the feeding pipe 506 extends above the two crushing rollers 303 inside the crushing box 301.

[0049] Specifically, the rotation of the conveyor shaft 504 can drive the spiral conveyor blade 505 to rotate inside the conveyor cylinder 502, thereby conveying large particles of material in the connecting box 501 upwards and then conveying them back to the crushing box 301 for cyclic crushing through the discharge pipe 506.

[0050] Please refer to this carefully. Figure 8 , Figure 9 The top end of the conveying shaft 504 extends to the upper surface of the conveying cylinder 502. The inner top wall of the rectangular box 401 is rotatably provided with a vertical shaft 507 extending to the upper surface of the crushing box 301. The vertical shaft 507 corresponds to the reciprocating threaded column 402, and a third bevel gear 508 is fixed at the bottom end of the vertical shaft 507. The third bevel gear 508 meshes with the second bevel gear 406 on the outer surface of the reciprocating threaded column 402. The top end of the vertical shaft 507 and the top end of the conveying shaft 504 are both fixed with a transmission wheel 509. The surfaces of the two transmission wheels 509 are fitted with a second transmission belt 5010.

[0051] Specifically, during the rotation of the reciprocating threaded column 402 and the second bevel gear 406, the third bevel gear 508 and the vertical shaft 507 can be driven to rotate automatically. The rotation of the vertical shaft 507, under the action of the two transmission wheels 509 and the second transmission belt 5010, drives the conveyor shaft 504 to rotate automatically.

[0052] In this invention, a circulation mechanism 500 is set up so that the waste material crushed by the two crushing rollers 303 can be filtered by the filter screen 503. The waste material that meets the particle size requirements falls to the guide plate 306 and is discharged, while the waste material with larger particles can pass through the filter screen 503 and enter the connecting box 501. When the cutter 404 continuously cuts the strip-shaped waste material entering the crushing box 301, the rotation of the reciprocating threaded column 402 and the second bevel gear 406 can drive the third bevel gear 508 and the vertical shaft 507 to rotate. The rotation of the vertical shaft 507 drives the conveying shaft 504 to rotate under the action of the two transmission wheels 509 and the second transmission belt 5010. The rotation of the conveying shaft 504 drives the spiral conveying blade 505 to rotate in the conveying cylinder 502, which conveys the large particles of waste material in the connecting box 501 upward and discharges them above the two crushing rollers 303 through the discharge pipe 506 for re-circulation and crushing. This effectively ensures that the particle size of the waste material discharged after crushing is consistent and further improves the processing efficiency of the waste material in the later stage.

[0053] Working Principle: The strip-shaped waste material generated by the vacuum forming machine body 100 is conveyed to the inside of the crushing box 301 by the conveying mechanism 200. The drive motor 304 is activated, driving one rotating shaft 302 to rotate. The rotation of one rotating shaft 302, under the action of two gear discs 305, drives another rotating shaft 302 to rotate in the opposite direction, thereby causing the two crushing rollers 303 to move simultaneously towards the center. This achieves the purpose of automatically crushing the strip-shaped waste material entering the crushing box 301. The crushed waste material is discharged under the action of the guide plate 306 and the discharge frame 307, thus enabling the vacuum forming equipment to automatically crush strip-shaped waste material. The purpose is to facilitate subsequent powder processing, effectively improving the efficiency of vacuum forming and subsequent waste disposal. Simultaneously, when the strip-shaped waste material enters the crushing box 301 and is crushed by the two crushing rollers 303, the rotation of the rotating shaft 302 drives the drive wheel 408 to rotate. The rotation of the drive wheel 408, under the action of the first transmission belt 409, drives the driven wheel 407 and the connecting rod 4010 to rotate. The rotation of the connecting rod 4010 drives the first bevel gear 405 to rotate. The rotation of the first bevel gear 405 drives the second bevel gear 406 and the reciprocating threaded column 402 to rotate. The rotation of the reciprocating threaded column 402 drives the rectangular plate 4... The 03 roller moves back and forth, thereby driving the cutter 404 to move back and forth as well, achieving the purpose of continuously and reciprocatingly cutting the strip of waste material entering the crushing box 301. This avoids the biting force of the two crushing rollers 303 pulling on the conveyed strip of waste material, thus ensuring the precision of the vacuum forming process. Moreover, the waste material crushed by the two crushing rollers 303 can be filtered by the filter screen 503, allowing waste material of the appropriate particle size to fall to the guide plate 306 and be discharged, while larger waste particles can pass through the filter screen 503 and enter the connecting box 501. Furthermore, when the cutter 404 continuously cuts the strip of waste material entering the crushing box 301, it moves back and forth... The rotation of the double-threaded column 402 and the second bevel gear 406 can drive the third bevel gear 508 and the vertical shaft 507 to rotate. The rotation of the vertical shaft 507, under the action of the two transmission wheels 509 and the second transmission belt 5010, drives the conveying shaft 504 to rotate. The rotation of the conveying shaft 504 drives the spiral conveying blade 505 to rotate in the conveying cylinder 502, conveying the large particles of waste in the connecting box 501 upward and discharging them through the discharge pipe 506 to the top of the two crushing rollers 303 for re-circulation and crushing. This effectively ensures that the particle size of the waste discharged after crushing is consistent, further improving the efficiency of waste processing in the later stage.
