Description

Technical Field

[0001] This invention relates to the field of mechanical transmission technology, specifically to a precision cutting intelligent detection device for plastic packaging production. Background Technology

[0002] Plastic packaging and plastic packaging products are taking up an increasingly larger share of the market, especially composite plastic flexible packaging, which has been widely used in the food, pharmaceutical, and chemical industries. Among them, food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. These products have brought great convenience to people's lives.

[0003] After plastic packaging film is manufactured, it needs to be precisely cut. Multi-axis equipment is generally used for the movement of the cutter and the cutting operation. The cutter is usually mounted on a turntable for adjustment of its direction. Most current turntables employ software and electrical limit switches to ensure safe and reliable operation. Both software and electrical limit switches require sensors on the turntable to monitor its rotation data in real time: software limit switches control the turntable's movement through servo system software; electrical limit switches control the turntable's movement through servo system electrical hardware.

[0004] Currently, the limit function of the turntable after adjustment is not good. The turntable lacks a locking structure when it stops running, and the drive structure and driven structure cannot be synchronously monitored. When wear or asynchrony occurs in the drive structure or driven structure, it cannot be detected in time. When the turntable is not adjusted accurately, it may cause damage to the internal connecting cables, optical fibers, liquid cooling pipes, etc.

[0005] To address this, we propose a precision cutting intelligent detection device for plastic packaging production. Summary of the Invention

[0057] Furthermore, the cutting module includes a first movable support 41, a second movable support 42, a cutter head support 47, and a cutter head changer 48;

[0058] The intelligent detection module includes a first electronic protractor 446, a second electronic protractor 448, a drive disk 45, a third movable bracket 46, and a side mounting component 49;

[0059] Specifically, the lower end of the first movable bracket 41 is fixedly connected to the second movable bracket 42. The first movable bracket 41 is equipped with a fixedly connected third motor 43, a first electronic protractor 446, and a second electronic protractor 448. The shaft of the third motor 43 is equipped with a fixedly connected fifth gear and a first synchronous pulley.

[0060] The upper surface of the second movable bracket 42 is provided with a fixedly connected guide post 421, a fourth motor 44, and a through arc-shaped guide groove 422 and a circular slot 423. The guide post 421 fixes the first movable bracket 41 and the second movable bracket 42 together.

[0061] The drive disc 45 is installed in the circular slot 423 and rotates. A slewing bearing is installed at the bottom of the drive disc 45. A second synchronous pulley is fixedly sleeved on the outside of the drive disc 45. The drive disc 45 has a first rotating shaft 431 rotatably connected inside. A bevel gear 432 and a sixth gear 433 are fixedly connected on the first rotating shaft 431. The sixth gear 433 meshes with the fifth gear. The third motor 43 drives the fifth gear, the sixth gear 433, the first rotating shaft 431 and the bevel gear 432 to rotate synchronously.

[0062] The fourth motor 44 has a fixedly connected seventh gear on its shaft. The second movable bracket 42 also has a rotating second shaft 441 and a third shaft 443. The second shaft 441 has a fixedly connected eighth gear and a ninth gear 442. The seventh gear meshes with the eighth gear. The fourth motor 44 drives the seventh gear, the eighth gear, the second shaft 441, and the ninth gear 442 to rotate synchronously. The third shaft 443 has a fixedly connected tenth gear 444 and a third synchronous pulley 445. The third synchronous pulley 445 is rotatably connected to the second synchronous pulley through the first synchronous belt 447. The tenth gear 444 meshes with the ninth gear 442.

[0063] When the second shaft 441 rotates, it drives the tenth gear 444, the third shaft 443, the third synchronous pulley 445, the second synchronous pulley, and the drive disk 45 to rotate synchronously. The top of the third shaft 443 is inserted into the first electronic protractor 446. When the third shaft 443 rotates, the first electronic protractor 446 acquires angle information and sends it to the PLC control system.

[0064] The lower end of the first movable bracket 41 is provided with a fourth rotating shaft that is rotatably connected. The top of the fourth rotating shaft is inserted into the second electronic protractor 448. When the fourth rotating shaft rotates, the second electronic protractor 448 acquires angle information and sends it to the PLC control system. The fourth rotating shaft is provided with a third synchronous pulley that is fixedly connected. The first synchronous pulley and the third synchronous pulley are rotatably connected through a synchronous belt. When the third motor 43 starts, it drives the fourth rotating shaft to rotate synchronously.

[0065] Furthermore, the drive disk 45 is provided with a first positioning hole 451, a second positioning hole 452, and a third positioning hole 453 arranged axially. The angle interval between the first positioning hole 451, the second positioning hole 452, and the third positioning hole 453 is 3°. The maximum angle between the first group of first positioning holes 451, the second positioning hole 452, and the third positioning hole 453 and the last group of first positioning holes 451, the second positioning hole 452, and the third positioning hole 453 does not exceed 240°.

[0066] Specifically, the first positioning hole 451 of the first group is 0°, the first positioning hole 451 of the second group is 3°, the first positioning hole 451 of the third group is 6°, and so on.

[0067] The first group of second positioning holes 452 is 1°, the second group of second positioning holes 452 is 4°, the third group of second positioning holes 452 is 7°, and so on.

[0068] The first group of third positioning holes 453 has a 2° angle, the second group of third positioning holes 453 has a 5° angle, the third group of third positioning holes 453 has an 8° angle, and so on.

[0069] Furthermore, the third movable support 46 is arc-shaped with an arc angle greater than 240°. The third movable support 46 is inserted into the arc-shaped guide groove 422 for sliding and lifting. The third movable support 46 is slidably engaged with the guide column 421, which provides lifting guidance for the third movable support 46. The upper end of the third movable support 46 is provided with a fixedly connected lifting component 461. The lower end of the lifting component 461 is provided with a first telescopic limit rod 462, a second telescopic limit rod 463, and a third telescopic limit rod 464. When the third movable support 46 is raised and lowered, it drives the lifting component 461, the first telescopic limit rod 462, the second telescopic limit rod 463, and the third telescopic limit rod 464 to rise and fall synchronously.

[0070] The first telescopic limit rod 462, the second telescopic limit rod 463, and the third telescopic limit rod 464 are all equipped with linear displacement sensors. When the first telescopic limit rod 462, the second telescopic limit rod 463, and the third telescopic limit rod 464 extend or retract, the linear displacement sensors obtain electrical signals and send them to the PLC control system.

[0071] The third movable bracket 46 is equipped with a second electric cylinder 465. The bottom end of the second electric cylinder 465 is fixedly connected to the second movable bracket 42, and the telescopic end of the second electric cylinder 465 is fixedly connected to the third movable bracket 46. The second electric cylinder 465 pulls the third movable bracket 46 to rise and fall. When the third movable bracket 46 descends to the lowest point, the first telescopic limit rod 462, the second telescopic limit rod 463, and the third telescopic limit rod 464 will be inserted into the first positioning hole 451, the second positioning hole 452, and the third positioning hole 453.

[0072] When the drive disc 45 is not rotating, the first telescopic limit rod 462 is inserted into the first positioning hole 451 to lock the drive disc 45, and the second telescopic limit rod 463 and the third telescopic limit rod 464 are squeezed and contracted.

[0073] When the drive disc 45 rotates 1°, the second telescopic limit rod 463 is inserted into the second positioning hole 452 to lock the drive disc 45, and the first telescopic limit rod 462 and the third telescopic limit rod 464 are squeezed and contracted.

[0074] When the drive disc 45 rotates 2°, the third telescopic limit rod 464 is inserted into the third positioning hole 453 to lock the drive disc 45, and the first telescopic limit rod 462 and the second telescopic limit rod 463 are squeezed and contracted.

[0075] Furthermore, the cutter head support 47 is fixed below the drive disk 45. When the drive disk 45 rotates, it drives the cutter head support 47 to rotate synchronously. The cutter head support 47 has a rotatably connected tool changer 48 inside, and a fixedly connected side mounting piece 49 on the side of the cutter head support 47.

[0076] Specifically, a ring tooth 481 is provided on one side of the tool changer 48. The ring tooth 481 meshes with a bevel gear 432. When the bevel gear 432 rotates, it drives the ring tooth 481 and the tool changer 48 to rotate synchronously. An axially arranged tool holder 482 is provided inside the tool changer 48. Different styles and functions of cutting blades 483 are provided inside the tool holder 482. An axially arranged positioning groove 484 is provided on the other side of the tool changer 48. The number and angle spacing of the positioning grooves 484 are the same as those of the tool holder 482.

[0077] A movable positioning rod 493 is provided above the side mounting component 49. The front end of the positioning rod 493 is provided with a fixedly connected positioning head 496, and the rear end of the positioning rod 493 is provided with an inclined pushing component 494. The upper end of the side mounting component 49 is provided with a fixedly connected first guide block 491 and second guide block 492. The positioning rod 493 passes through the first guide block 491 and the second guide block 492 and slides between them. A spring 495 is sleeved on the positioning rod 493. In the absence of external force, the spring 495 pulls the positioning rod 493 backward.

[0078] The drive disc 45 rotates at an angle not exceeding 240°, and the side mounting piece 49 rotates accordingly to adjust the angle. Since the third movable bracket 46 is arc-shaped and the arc angle is greater than 240°, the third movable bracket 46 can contact the tilting pusher 494 when it descends.

[0079] When the third movable support 46 descends, its bottom end contacts the tilting pusher 494. As the third movable support 46 continues to descend, it pushes the tilting pusher 494, the positioning rod 493, and the positioning head 496 closer to the other side of the tool changer 48. When the third movable support 46 descends to its lowest point, the positioning head 496 inserts into the designated positioning groove 484, thereby locking the tool changer 48.

[0080] Working principle of the invention:

[0081] When in use, the plastic packaging film is pulled out by the machine and placed on the bottom support 1. It is positioned manually or by a clamping structure. Then, the multi-axis equipment drives the cutting component 4 to move and cut.

[0082] The fourth motor 44 starts and drives the second rotating shaft 441, the third rotating shaft 443, and the drive disk 45 to rotate and adjust the angle of the cutter head bracket 47, the cutter changing disk 48, and the side mounting piece 49. Then the third motor 43 starts and drives the first rotating shaft 431 and the bevel gear 432 to rotate. The bevel gear 432 drives the cutter changing disk 48 to rotate and select the cutter 483. After the adjustment is completed, the third motor 43 and the fourth motor 44 stop. The first electronic protractor 446 and the second electronic protractor 448 monitor in real time.

[0083] The second electric cylinder 465 pulls the third movable bracket 46 down. When the third movable bracket 46 descends to the lowest point, the first telescopic limit rod 462, the second telescopic limit rod 463, and the third telescopic limit rod 464 will be inserted into the first positioning hole 451, the second positioning hole 452, and the third positioning hole 453, thereby locking the drive plate 45. After the drive plate 45 is locked, the tool disc bracket 47, the tool changing disc 48, and the side mounting piece 49 are locked to rotate laterally.

[0084] When the third movable bracket 46 descends, its bottom end contacts the tilting pusher 494. As the third movable bracket 46 continues to descend, it pushes the tilting pusher 494, the positioning rod 493, and the positioning head 496 closer to the other side of the tool changer 48. When the third movable bracket 46 descends to its lowest point, the positioning head 496 inserts into the designated positioning groove 484, thereby locking the tool changer 48 in a longitudinal rotation.
