Description

Technical Field

[0001] This utility model relates to the field of sealing and cutting machine technology, and in particular to an automatic correction device for a PE roll film sealing and cutting machine. Background Technology

[0002] A sealing and cutting machine is an automated device used in the packaging industry. Its main function is to seal and cut roll films (such as PE film, POF heat shrink film, etc.) to achieve rapid wrapping of products. It is widely used in the food, pharmaceutical, daily necessities, and electronics industries. It is suitable for packaging single or grouped products, such as wrapping biscuits, cosmetics, and hardware parts in film and sealing them to form a sealed package. When used with a heat shrink machine, it can achieve a tight shrink packaging effect.

[0003] In existing sealing and cutting machines, the packaging film may deviate from the center position of the roller due to other factors during operation. This may cause problems such as skewed sealing and cutting positions, incomplete sealing, or even film tearing. This not only affects the sealing and aesthetics of the product packaging, but may also lead to rework due to substandard packaging, reduce production efficiency, and cause unnecessary waste of resources. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic correction device for a PE roll film sealing and cutting machine.

[0005] This utility model is achieved by the following technical solution: an automatic correction device for a PE roll film sealing and cutting machine, including a sealing and cutting machine, a photoelectric sensor is provided on the inner wall of the sealing and cutting machine, a correction component is provided on the inner wall of the sealing and cutting machine, a feeding component is provided on the outer wall of the sealing and cutting machine, and an adjustment component is provided on the inner wall of the sealing and cutting machine.

[0006] The correction assembly includes a rotating groove, a rotating wheel rotatably connected to the outer wall of the rotating groove, a fixed rod rotatably connected to the inner wall of the rotating wheel, a base plate fixedly connected to the top of the fixed rod, a triangular block fixedly connected to the top of the base plate, a correction wheel rotatably connected inside the triangular block, a rotating rod fixedly connected inside the base plate, a worm gear fixedly connected to the outer wall of the rotating rod, a worm gear meshing with the worm, the worm being rotatably connected inside the sealing and cutting machine, and a servo motor fixedly connected to the outer end of the worm.

[0007] As a further improvement to the above solution, the rotating groove is opened at the bottom of the inner wall of the sealing and cutting machine, the rotating rod is rotatably connected inside the sealing and cutting machine, and the servo motor is fixedly connected to the inner wall of the sealing and cutting machine.

[0008] The above technical solution involves installing a photoelectric sensor on the inner wall of the sealing and cutting machine. This sensor monitors the film position in real time. When the film roll deviates, the sensor sends a signal, triggering a servo motor to rotate a worm gear. The worm gear, through a worm wheel, drives a rotating rod, which is fixed to the base plate. A fixing rod is also fixed to the bottom of the base plate, driving a rotating wheel to rotate on the outer wall of the rotating groove, providing auxiliary support to the base plate. A triangular block is fixed to the top of the base plate, and a correction wheel rotates inside this block, finely adjusting its angle. This uses friction to push the film roll back to the correct position, effectively preventing the packaging film from deviating from the center in existing technologies. This ensures a firm and flat seal, improves packaging airtightness, reduces resource waste, avoids film tearing due to packaging problems, saves raw materials, and lowers production costs.

[0009] As a further improvement to the above solution, the feeding assembly includes a connecting block, which is fixedly connected to the outer wall of the sealing and cutting machine. A fixing rod is fixedly connected inside the connecting block, and a connecting plate is rotatably connected to the outer wall of the fixing rod.

[0010] As a further improvement to the above solution, a slot is provided on the outer wall of the connecting plate, a unwinding wheel is rotatably connected to the outer wall of the slot, and a connecting block is fixedly connected to the outer wall of the connecting plate.

[0011] As a further improvement to the above solution, a fixing rod 2 is fixedly connected inside the connecting block 1, a hollow column is rotatably connected to the outer wall of the fixing rod 2, and a hydraulic cylinder is fixedly connected to the outer wall of the hollow column.

[0012] As a further improvement to the above solution, a fixing block is fixedly connected to the end of the hydraulic cylinder away from the hollow column, a fixing rod three is rotatably connected to the inner wall of the fixing block, a connecting block two is fixedly connected to the outer wall of the fixing rod three, and the connecting block two is fixedly connected to the outer wall of the sealing and cutting machine.

[0013] Through the above technical solution, the output end of the hydraulic cylinder is fixed to the hollow column, causing the hollow column to rotate on the outer wall of the second fixed rod. At the same time, the hydraulic cylinder rotates on the outer wall of the third fixed rod via the fixed block. The third fixed rod is fixed to the second connecting block, and the second fixed rod is fixed to the first connecting block. This allows the hydraulic cylinder to operate more flexibly and prevents jamming. The first connecting block drives the connecting plate to move, causing the connecting plate to rotate around the first fixed rod. The connecting block is fixed to the first fixed rod, thus supporting the first fixed rod. This eliminates the need for personnel to lift raw materials to high places for installation, significantly reducing labor intensity and minimizing potential safety hazards caused by working at heights. It also makes the material loading process more labor-saving and safer.

[0014] As a further improvement to the above solution, the adjustment component includes a support plate, which is fixedly connected to the inner wall of the sealing and cutting machine. A sliding groove is provided inside the support plate, and a sliding plate is slidably connected to the outer wall of the sliding groove. The sliding plate is fixedly connected to the outer wall of the photoelectric sensor. A bidirectional threaded rod is threadedly connected inside the sliding plate. The bidirectional threaded rod is rotatably connected to the inside of the sealing and cutting machine, and a handle is fixedly connected to the outer end of the bidirectional threaded rod.

[0015] With the above technical solution, the operator rotates the handle to drive the bidirectional threaded rod to rotate, causing the sliding plate to slide along the groove. The sliding plate is fixed to the photoelectric sensor, thereby realizing the adjustment of the photoelectric sensor position. It can be adjusted for films of different widths, avoiding sensor detection failure due to changes in film width, meeting diverse packaging needs, and improving the flexibility of the equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a photoelectric sensor installed on the inner wall of a sealing and cutting machine to monitor the film position in real time. When the film roll deviates, the photoelectric sensor sends a signal, triggering a servo motor to drive a worm gear. The worm gear, in turn, drives a rotating rod to rotate via a worm wheel. The rotating rod is fixed to a base plate, and a fixing rod is also fixed to the bottom of the base plate. This fixing rod drives a rotating wheel to rotate on the outer wall of the rotating groove, providing auxiliary support to the base plate. A triangular block is fixed to the top of the base plate, and a correction wheel rotates inside the triangular block. The correction wheel then finely adjusts its angle, using friction to push the film roll back to the correct position. This effectively avoids the situation where the packaging film deviates from the center, as is common in existing technologies. It ensures a firm and flat seal, improves packaging airtightness, reduces resource waste, and prevents film tearing caused by packaging problems. This also saves raw materials and reduces production costs.

[0018] This invention allows a person to rotate a handle, which drives a bidirectional threaded rod to rotate, causing a sliding plate to slide along a groove. The sliding plate is fixed to a photoelectric sensor, thereby enabling the adjustment of the photoelectric sensor's position. This allows for adjustment and detection of films of different widths, avoiding sensor failure due to changes in film width, meeting diverse packaging needs, and improving the flexibility of the equipment.

[0031] The feeding assembly 4 includes a connecting block 401, which is fixedly connected to the outer wall of the sealing and cutting machine 1. A fixing rod 402 is fixedly connected inside the connecting block 401, and a connecting plate 403 is rotatably connected to the outer wall of the fixing rod 402.

[0032] The outer wall of the connecting plate 403 has a slot 404, and the outer wall of the slot 404 is rotatably connected to a winding wheel 405. The outer wall of the connecting plate 403 is fixedly connected to a connecting block 406.

A fixing rod 411 is rotatably connected to the inner wall of the fixing block 410. A connecting block 412 is fixedly connected to the outer wall of the fixing rod 411. The connecting block 412 is fixedly connected to the outer wall of the sealing and cutting machine 1.

[0035] The adjustment assembly 5 includes a support plate 501, which is fixedly connected to the inner wall of the sealing and cutting machine 1. A sliding groove 502 is provided inside the support plate 501. A sliding plate 503 is slidably connected to the outer wall of the sliding groove 502. The sliding plate 503 is fixedly connected to the outer wall of the photoelectric sensor 2. A bidirectional threaded rod 504 is threadedly connected inside the sliding plate 503.

[0036] The implementation principle of the automatic correction device for a PE roll film sealing and cutting machine in this embodiment is as follows: A photoelectric sensor 2 is installed on the inner wall of the sealing and cutting machine 1. The photoelectric sensor 2 monitors the film position in real time. When the roll film deviates, the photoelectric sensor 2 sends a signal, and the servo motor 310 starts to drive the worm gear 309 to rotate. The worm gear 309 drives the rotating rod 307 to rotate through the driving worm wheel 308. The rotating rod 307 is fixed to the base plate 304, causing the base plate 304 to rotate. At the same time, a fixing rod 303 is fixed at the bottom of the base plate 304. The fixing rod 303 drives the rotating wheel 302 to rotate on the outer wall of the rotating groove 301. The fixing rod 303 provides auxiliary support for the base plate 304, ensuring that the base plate 304 can rotate stably. A triangular block 305 is fixed to the top of the base plate 304. The alignment wheel 306 rotates inside the triangular block 305. At this time, the alignment wheel 306 adjusts its angle slightly and uses friction to push the film roll back to the correct position. This effectively avoids the situation where the packaging film deviates from the center in the prior art, ensuring a firm and flat seal, improving packaging sealing, reducing resource waste, and avoiding situations such as film tearing and product waste caused by packaging problems. It also saves raw materials and reduces production costs. When it is necessary to feed the unwinding wheel 405, the output end of the hydraulic cylinder 409 is fixed to the hollow column 408, causing the hollow column 408 to rotate on the outer wall of the fixed rod 407. At the same time, the hydraulic cylinder 409 rotates on the fixed rod through the fixed block 410. The outer wall of the third 411 is fixed with the second connecting block 412, and the second fixing rod 407 is fixed with the first connecting block 406. This allows the hydraulic cylinder 409 to operate more flexibly and prevents jamming. The first connecting block 406 drives the connecting plate 403 to move, causing the connecting plate 403 to rotate around the first fixing rod 402 as the center. The connecting block 401 is fixed with the first fixing rod 402, thus supporting the first fixing rod 402. This eliminates the need for personnel to lift raw materials to high places for installation, significantly reducing labor intensity and minimizing safety hazards that may arise from working at heights. It makes the material loading process more labor-saving and safer. At the same time, the unwinding wheel 405 rotates on the outer wall of the slot 404, making the connecting... When plate 403 moves, unwinding wheel 405 remains stationary, ensuring stable feeding. Operators rotate handle 505, driving bidirectional threaded rod 504 to rotate, causing sliding plate 503 to slide along groove 502. Sliding plate 503 is fixed to photoelectric sensor 2, allowing for position adjustment of photoelectric sensor 2. This adjustment can be tailored to films of different widths, preventing sensor failure due to film width variations, meeting diverse packaging needs, and improving equipment flexibility. The aforementioned photoelectric sensor 2 is a Keyence PR-MB30N1, employing diffuse reflection detection with a detection distance of 0-30mm. It accurately identifies PE film edges and has a response speed of 100μs, ensuring detection accuracy during high-speed operation.
