AI Technical Summary
Common new vertical L-shaped sealing and cutting film packaging machines with rear-mounted bottom film distribution lack adjustment functions, which cannot guarantee the accuracy of the product movement path. As a result, when the limiting component limits products of different heights, the products are prone to detaching due to vibration, affecting the film coating quality.
The knob drives the lead screw to rotate forward or backward, causing the T-block to move up or down. The T-block then moves the inner push plate up or down, allowing the height of the outer and inner push plates to be adjusted to match the product, thus achieving height adjustment and ensuring that the product is completely blocked when vibrating.
It enables flexible adjustment of the limit height, preventing the product from detaching due to vibration and ensuring the stability and accuracy of the coating quality.

Abstract
Description
A novel vertical L-shaped sealing and cutting film-feeding packaging machine with rear-mounted bottom-feeding film. Technical Field
[0001] This utility model relates to the field of packaging machine technology, and in particular to a novel vertical L-shaped sealing and cutting film-laying packaging machine with rear-mounted bottom film distribution. Background Technology
[0002] Sealing and cutting machines are fully automatic, unmanned packaging machines widely used in mass production packaging operations. They are highly efficient, automatically feeding and punching film, automatically sealing and cutting film, and automatically rolling up waste material. They can be used in conjunction with automated packaging lines and are the first choice for product sealing, cutting, and heat shrinking. During operation, products are transported from the previous process to the packaging machine via a conveyor device. At this point, it is necessary to limit the movement trajectory of the products to ensure the quality of film coating. Since the height of each product is different, the height of the limiting components needs to be adjusted to match the height of the products.
[0003] The common new type of vertical L-shaped sealing and cutting film packaging machine with rear bottom placement only includes the packaging function, which can heat and seal the product after bagging. However, it lacks the adjustment function and cannot guarantee the accuracy of the product movement path. It is easy for the limiting component to detach from the limiting component when limiting products of different heights due to vibration during movement. This causes the product position to shift and affects the film coating quality.
[0004] Therefore, to address the lack of adjustment functionality in the aforementioned novel vertical L-type sealing and cutting film packaging machine with rear-mounted bottom-loading, a new type of vertical L-type sealing and cutting film packaging machine with rear-mounted bottom-loading can be designed. A knob drives a lead screw to rotate forward or backward. The forward or reverse rotation of the lead screw causes a T-shaped block to move up or down, which in turn causes the inner push plate to move up or down. When the combined height of the outer and inner push plates matches the product height, the lead screw stops rotating. In this way, when the product vibrates, the combination of the outer and inner push plates can completely block the product, thus achieving the function of adjusting the limit height. Summary of the Invention
[0005] To overcome the common problem of new vertical L-shaped sealing and cutting film packaging machines with rear-mounted bottom-layout film packaging, which lack adjustment functions and cannot guarantee the accuracy of product movement path, it is easy for the limiting component to detach from the limiting component when limiting products of different heights due to vibration during movement. This causes the product position to shift and affects the film coating quality.
[0006] The technical solution of this utility model is as follows: A novel vertical L-shaped sealing and cutting film packaging machine with rear-mounted bottom film placement, including a packaging frame; it also includes a drive box, a drive air pump, an outer push plate, a bottom plate, a lead screw, a knob, a telescopic groove, an inner push plate, a sliding groove, and a T-shaped block. The drive box is located at the right end of the front top of the packaging frame. Two drive air pumps are symmetrically arranged on the right side of the top of the drive box. The output ends of the two drive air pumps are connected to the outer push plate. The bottom of the outer push plate is located at the bottom of the bottom plate. A lead screw is rotatably connected to the middle of the front top of the bottom plate. A knob is located at the top of the lead screw. A telescopic groove is opened on the top of the outer push plate. An inner push plate is arranged inside the telescopic groove. A sliding groove is opened in the middle of the front side of the outer push plate corresponding to the position of the lead screw. A T-shaped block is arranged in the middle of the front side of the outer push plate corresponding to the position of the sliding groove. The rear end of the T-shaped block passes through the sliding groove and is connected to the inner push plate. The lead screw is threadedly connected to the T-shaped block.
[0007] Preferably, the screw is driven to rotate forward or backward by a knob. The forward or reverse rotation of the screw causes the T-block to move up or down, and the T-block in turn causes the inner push plate to move up or down. When the combined height of the outer push plate and the inner push plate matches the product height, the screw rotation stops. In this way, when the product vibrates, the combination of the outer push plate and the inner push plate can completely block the product, realizing the function of adjusting the limit height. This solves the problem of common new vertical L-shaped sealing and cutting post-positioned bottom film packaging machines, which only have the packaging function and can heat and seal the product after bagging, but lack the adjustment function. They cannot guarantee the accuracy of the product movement path, and are prone to problems such as the limit component limiting products of different heights. Products that exceed the limit component will disengage from the limit component due to vibration during movement, resulting in product position deviation and affecting the film coating quality.
[0008] As a preferred option, four self-locking telescopic feet are symmetrically arranged at the left and right ends of the front and rear sides of the bottom of the packaging frame, and four universal wheels are symmetrically arranged at the four corners of the bottom of the packaging frame.
[0009] Preferably, an upper film frame is provided on the rear side of the packaging frame, and a film conveying assembly is provided at the top inside the upper film frame.
[0010] Preferably, a support rod is provided at the top of the middle of the front side of the upper membrane frame, and a PLC controller is provided at the front end of the support rod.
[0011] Preferably, a first conveying component is provided on the right side of the top of the packaging frame, and a second conveying component is provided on the left side of the top of the packaging frame.
[0012] Preferably, a sealing and cutting component is provided above the left front end of the upper membrane frame, corresponding to the position of the second conveying component.
[0013] Preferably, a protective cover is movably connected to the top of the left front end of the upper film frame, corresponding to the position of the sealing and cutting component, via a hinge.
[0014] The beneficial effects of this utility model are:
[0015] 1. The screw is driven to rotate forward or backward by a knob. The forward or reverse rotation of the screw causes the T-block to move up or down, which in turn causes the inner push plate to move up or down. When the combined height of the outer and inner push plates matches the product height, the screw rotation stops. In this way, when the product vibrates, the combination of the outer and inner push plates can completely stop the product, realizing the function of adjusting the limit height. This solves the problem of common new vertical L-type sealing and cutting packaging machines with post-positioning and bottom-laying film packaging, which only have the packaging function and can heat and seal the product after bagging, but lack the adjustment function. It cannot guarantee the accuracy of the product movement path. When the limit component limits products of different heights, products that exceed the limit component will disengage from the limit component due to vibration during movement, resulting in product position deviation and affecting the film coating quality.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to Figures 1-4. This utility model provides an embodiment: a novel vertical L-shaped sealing and cutting film packaging machine with rear-mounted bottom-release film, including a packaging frame 1; it also includes a drive box 2, a drive air pump 3, an outer push plate 4, a base plate 5, a lead screw 6, a knob 7, a telescopic groove 8, an inner push plate 9, a sliding groove 10, and a T-shaped block 11. The drive box 2 is located at the right end of the front top of the packaging frame 1. Two drive air pumps 3 are symmetrically arranged on the right side of the top of the drive box 2. The two drive air pumps 3 are located behind the drive box 1. The output end is connected to an outer push plate 4. A base plate 5 is provided at the bottom of the outer push plate 4. A lead screw 6 is rotatably connected to the middle of the front side of the top of the base plate 5. A knob 7 is provided at the top of the lead screw 6. A telescopic groove 8 is provided on the top of the outer push plate 4. An inner push plate 9 is provided inside the telescopic groove 8. A sliding groove 10 is provided on the middle of the front side of the outer push plate 4 corresponding to the position of the lead screw 6. A T-shaped block 11 is provided on the middle of the front side of the outer push plate 4 corresponding to the position of the sliding groove 10. The rear end of the T-shaped block 11 passes through the sliding groove 10 and connects with the inner push plate 9. The push plate 9 is connected, and the lead screw 6 is threadedly connected to the T-block 11. The lead screw 6 is driven to rotate forward or backward by the knob 7. The forward or reverse rotation of the lead screw 6 drives the T-block 11 to move up or down, and the T-block 11 drives the inner push plate 9 to move up or down. When the combined height of the outer push plate 4 and the inner push plate 9 matches the product height, the rotation of the lead screw 6 stops. In this way, when the product vibrates, the combination of the outer push plate 4 and the inner push plate 9 can completely block the product, realizing the function of adjusting the limit height. This solves the problem of common new vertical L-type sealing and cutting film packaging machines with rear-mounted bottom film placement, which only have the packaging function and can heat and seal the product after bagging, but lack the adjustment function. They cannot guarantee the accuracy of the product movement path. When the limit component limits products of different heights, products that exceed the limit component will disengage from the limit component due to vibration during movement, resulting in product position deviation and affecting the film coating quality.
[0023] Please refer to Figures 2-4. In this embodiment, four self-locking telescopic feet 12 are symmetrically arranged at the left and right ends of the front and rear sides of the bottom of the packaging frame 1. Four casters 13 are symmetrically arranged at the four corners of the bottom of the packaging frame 1. An upper film frame 14 is arranged on the rear side of the packaging frame 1. A film conveying assembly 15 is arranged at the top inside the upper film frame 14. A support rod 16 is arranged at the top center of the front side of the upper film frame 14. A PLC controller 17 is arranged at the front end of the support rod 16. The PLC controller 17 controls the start of the drive air pump 3. The drive air pump 3 drives the outer push plate 4 to move towards the upper film frame 14 according to the width of the product until the distance between the outer push plate 4 and the rear baffle at the top of the first conveying assembly 18 matches the width of the product. The product is then conveyed from the previous conveying device to the first conveying assembly 18. The movement trajectory of the product is limited by the outer push plate 4 and the baffle on the rear side of the top of the first conveying assembly 18. Then, the first conveying assembly 18 moves the product to the second conveying assembly 19. As the product enters the second conveying assembly 19, it is fitted into the packaging film. At this time, both the first conveying assembly 18 and the second conveying assembly 19 are stopped. Then, the sealing and cutting assembly 20 is started. The sealing and cutting assembly 20 cuts the packaging film conveyed from the film conveying assembly 15. After the packaging film is cut, the second conveying assembly 19 continues to start. The second conveying assembly 19 conveys the product with the outer packaging film to the next heat shrink process.
[0024] Please refer to Figures 1-4. In this embodiment, a first conveying assembly 18 is provided on the right side of the top of the packaging frame 1, and a second conveying assembly 19 is provided on the left side of the top of the packaging frame 1. A sealing and cutting assembly 20 is provided above the front left end of the upper film frame 14, corresponding to the position of the second conveying assembly 19. A protective cover 21 is movably connected to the top of the front left end of the upper film frame 14, corresponding to the position of the sealing and cutting assembly 20, via a hinge. When it is necessary to adjust the height of the limit according to the height of the product, the screw 6 is driven to rotate forward or backward by the knob 7. The forward or reverse rotation of the screw 6 drives the T-block 1. When the outer push plate 4 and the inner push plate 9 move upward or downward, the screw 6 stops rotating. When the combined height of the outer push plate 4 and the inner push plate 9 matches the product height, the screw 6 stops rotating. In this way, when the product vibrates, the combination of the outer push plate 4 and the inner push plate 9 can completely block the product, realizing the function of adjusting the limit height. This prevents the problem that when the limit component limits products of different heights, products exceeding the limit component will disengage from the limit component due to vibration during movement, resulting in product position deviation and affecting the coating quality.
[0025] During operation, the PLC controller 17 controls the start of the drive air pump 3. The drive air pump 3 drives the outer push plate 4 to move upwards towards the film frame 14 according to the product width, until the distance between the outer push plate 4 and the rear baffle at the top of the first conveying assembly 18 matches the product width. Then, the product is conveyed from the previous conveying device to the first conveying assembly 18. The movement trajectory of the product is limited by the outer push plate 4 and the rear baffle at the top of the first conveying assembly 18. Subsequently, the first conveying assembly 18 moves the product to the second conveying assembly 19. As the product enters the second conveying assembly 19, it is simultaneously encased in the packaging film. At this point, both the first and second conveying assemblies 18 are stopped. Then, the sealing and cutting assembly 20 is started. The sealing and cutting assembly 20 cuts the packaging film conveyed by the film conveying assembly 15. After the packaging film is cut, the second conveying assembly 19 continues to start, and the product with the outer packaging film is conveyed to the next heat shrink process through the second conveying assembly 19. When it is necessary to adjust the limit height according to the height of the product, the screw 6 is driven to rotate forward or backward by the knob 7. The screw 6 rotates forward or backward, and drives the T-block 11 to move up or down. The T-block 11 then drives the inner push plate 9 to move up or down. When the height of the outer push plate 4 and the inner push plate 9 combined is adapted to the height of the product, the screw 6 stops rotating. In this way, when the product vibrates, the combination of the outer push plate 4 and the inner push plate 9 can completely block the product, realizing the function of adjusting the limit height.
[0026] Through the above steps, the screw 6 is driven to rotate forward or backward by the knob 7. The forward or reverse rotation of the screw 6 causes the T-block 11 to move up or down, and the T-block 11 in turn causes the inner push plate 9 to move up or down. When the combined height of the outer push plate 4 and the inner push plate 9 matches the product height, the screw 6 stops rotating. In this way, when the product vibrates, the combination of the outer push plate 4 and the inner push plate 9 can completely block the product, realizing the function of adjusting the limit height. This solves the problem of common new vertical L-shaped sealing and cutting film packaging machines with rear-mounted bottom film placement, which only have the packaging function and can heat and seal the product after bagging, but lack the adjustment function. They cannot guarantee the accuracy of the product movement path, and it is easy for the limit component to limit products of different heights. Products that exceed the limit component will disengage from the limit component due to vibration during movement, resulting in product position deviation and affecting the film coating quality.
