Technical Field
[0001] This utility model belongs to the field of packaging technology, specifically relating to a sealing and cutting device for intelligent packaging machines that integrates cutting and punching. Background Technology
[0002] Intelligent packaging machines are devices capable of completing all or part of the product and commodity packaging process. The packaging process includes main steps such as filling, wrapping, and sealing. When using film packaging for products, intelligent packaging machines typically fill a fixed quantity of the product into a continuous film bag, then use a sealing and cutting device to seal the film, cut it, and punch hanging holes to complete the packaging of one bag of products. This process is repeated to complete the packaging of all products. The sealing and cutting device is used for mass production packaging assembly line operations, with high working efficiency. Automatic sealing, cutting, and punching hanging holes are completed continuously and automatically, making it suitable for industries such as food, pharmaceuticals, daily chemicals, and hardware.
[0003] Existing film sealing and cutting devices on the market can only seal, cut, and punch holes for flat films. When dealing with angled films, they cannot adjust the angle, which limits the processing range. In addition, after punching holes for the film, film residue caused by punching will remain inside the punching knife or heat sealing block. This residue cannot be automatically removed, and over time it will cause sealing and cutting abnormalities. To address this, we have proposed a sealing and cutting device for intelligent packaging machines that integrates cutting and punching. Utility Model Content
[0004] The purpose of this utility model is to provide a sealing and cutting device for intelligent packaging machines that integrates cutting and punching, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing and cutting device for an intelligent packaging machine that integrates cutting and punching, comprising a frame, a rotating shaft rotatably connected to the top of the frame, a protective cover fixedly connected to the bottom of the rotating shaft, a cylinder fixedly connected inside the protective cover, the output end of the cylinder penetrating the bottom of the protective cover, a bracket fixedly connected to the outside of the protective cover, two connecting rods fixedly connected to the bottom of the bracket, a first mounting plate fixedly connected to the bottom of the two connecting rods, a fixed plate fixedly connected to the output end of the cylinder, the fixed plate slidably connected to the outside of the two connecting rods, two sliding rods slidably connected inside the fixed plate, the sliding rods penetrating the fixed plate, a second mounting plate fixedly connected to the bottom of the sliding rods, a second heat sealing block fixedly connected to the lower end face of the second mounting plate, a second heat insulation pad provided between the second mounting plate and the second heat sealing block, and a first spring fixing the second mounting plate and the fixed plate.
[0006] In a preferred embodiment, a heat-sealing block is fixedly connected to the upper end face of the first mounting plate, and a heat insulation pad is provided between the first mounting plate and the first heat-sealing block.
[0007] In a preferred embodiment, a second spring is fixedly connected to the bottom of the fixing plate, and a cutter fixing block is fixedly connected to the bottom of the second spring. A cutter is provided on the front of the cutter fixing block, and the cutter is fixed to the front of the cutter fixing block by bolts. The cutter penetrates the second heat sealing block.
[0008] In a preferred embodiment, a rotating cylinder is rotatably connected to the bottom of the first mounting plate, and the outside of the rotating cylinder is fixedly connected to the bottom of the frame.
[0009] In a preferred embodiment, a gear is fixedly connected to the top of the rotating shaft, upright plates are fixedly connected to both sides of the top of the frame, and columns are fixedly connected to both sides of the top of the frame. A pawl is rotatably connected to the outside of the column, and the pawl is fixedly connected to the upright plate by a No. 3 spring. A lever is fixedly connected to the top of the pawl.
[0010] In a preferred embodiment, a punching tool is internally threaded onto the tool fixing block, the punching tool penetrates the second heat sealing block, and a top rod is fixedly connected to the bottom of the fixing plate, the top rod being slidably connected inside the punching tool.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This intelligent packaging machine uses a sealing and cutting device that integrates cutting and punching. By setting up a rotating shaft, gears, pawls, and a No. 3 spring, the pawl can be rotated by pulling one of the levers, causing the pawl to disengage from the gear. This allows the gear to drive the rotating shaft to rotate, thereby adjusting the angle of the No. 1 and No. 2 heat sealing blocks. It is suitable for sealing and cutting oblique films, avoiding the problem that it can only seal and cut flat films.
[0013] 2. This intelligent packaging machine uses a sealing and cutting device that integrates cutting and punching. By setting a second spring and a top rod, after the sealing, cutting and bag hanging hole punching operations are completed, the cylinder continues to push out, causing the fixed plate to drive the top rod to continue moving inside the punching knife until the top rod protrudes from the first mounting plate. During the movement of the top rod, the film remaining inside the punching knife or the first heat sealing block due to the bag hanging hole punching can be pushed out, avoiding the problem that the residual film cannot be automatically discharged, which would lead to abnormal sealing and cutting effects in the future.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0023] Please see Figures 1-6This utility model provides a sealing and cutting device for an intelligent packaging machine that integrates cutting and punching. It includes a frame 1. For integrated sealing, cutting, and bag-hanging hole punching operations on the film, a rotating shaft 2 is rotatably connected to the top of the frame 1. A protective cover 3 is fixedly connected to the bottom of the rotating shaft 2. A cylinder 4 is fixedly connected inside the protective cover 3, and the output end of the cylinder 4 passes through the bottom of the protective cover 3. A bracket 5 is fixedly connected to the outside of the protective cover 3. Two connecting rods 6 are fixedly connected to the bottom of the bracket 5, and a mounting plate 7 is fixedly connected to the bottom of the two connecting rods 6. The output end of the cylinder 4 is fixedly... A fixed plate 8 is fixedly connected to the outside of two connecting rods 6. Two sliding rods 9 are slidably connected inside the fixed plate 8, passing through it. A second mounting plate 10 is fixedly connected to the bottom of the sliding rods 9. A second heat-sealing block 13 is fixedly connected to the lower end of the second mounting plate 10. A second heat insulation pad is placed between the second mounting plate 10 and the second heat-sealing block 13. The second mounting plate 10 and the fixed plate 8 are fixedly connected by a first spring 11. A first heat-sealing block 12 is fixedly connected to the upper end of the first mounting plate 7. The first mounting plate 7 and the first heat-sealing block 12... A heat insulation pad is placed between blocks 12. A second spring 16 is fixedly connected to the bottom of the fixing plate 8. A cutter fixing block 15 is fixedly connected to the bottom of the second spring 16. A cutter 17 is provided on the front of the cutter fixing block 15 and is fixed to the front of the cutter fixing block 15 by bolts. The cutter 17 penetrates the second heat sealing block 13. A punching tool 18 is threaded inside the cutter fixing block 15 and penetrates the second heat sealing block 13. The frame 1 is fixed to the working area using a tool. The film is placed between the first heat sealing block 12 and the second heat sealing block 13. When cylinder 4 extends, the fixing plate 8 moves on the connecting rod 6, thereby driving spring 11, mounting plate 10, and heat sealing block 13 to move towards heat sealing block 12. Heat sealing block 12 and heat sealing block 13 engage with each other to seal the film. As cylinder 4 continues to extend, spring 11 is compressed. At this time, fixing plate 8 continues to drive spring 16, tool fixing block 15, cutter 17, and punching knife 18 to move, which can simultaneously cut the film and punch holes for hanging bags, thus achieving the purpose of integrated operation of sealing, cutting, and punching holes for hanging bags.
[0024] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6In order to push out the film residue caused by punching the bag holes, a push rod 14 can be fixedly connected to the bottom of the fixed plate 8. The push rod 14 is slidably connected to the inside of the punching knife 18. The bottom of the first mounting plate 7 is rotatably connected to the rotating cylinder 19, and the outside of the rotating cylinder 19 is fixedly connected to the bottom of the frame 1. When the cylinder 4 continues to push out, the second spring 16 is compressed. The fixed plate 8 drives the push rod 14 to continue to move. The push rod 14 moves inside the punching knife 18 until the push rod 14 protrudes from the first mounting plate 7. The push rod 14 can push out the film residue inside the punching knife 18 or the first heat sealing block 12, thereby achieving the purpose of pushing out the film residue caused by punching the bag holes.
[0025] Please see Figure 1 , Figure 3 and Figure 4 To operate the beveled film, a gear 20 is fixedly connected to the top of the rotating shaft 2, and upright plates are fixedly connected to both sides of the top of the frame 1. Columns are fixedly connected to both sides of the top of the frame 1, and pawls 21 are rotatably connected to the outside of the columns. Pawls 21 are fixedly connected to the upright plates via a third spring 22, and a lever 23 is fixedly connected to the top of the pawls 21. When it is necessary to operate the beveled film, one of the levers 23 is pulled, causing the lever 23 to drive the pawls 21 to rotate, disengaging one of the pawls 21 from the gear 20. This allows the rotating shaft 2 to rotate, thereby causing the protective cover 3, connecting rod 6, fixing plate 8, etc., to rotate, thus changing the angle between the first heat sealing block 12 and the second heat sealing block 13, achieving the purpose of operating the beveled film.
[0026] The working principle and usage process of this utility model are as follows: First, the frame 1 is fixed in the working area using a tool. The film is placed between the first heat-sealing block 12 and the second heat-sealing block 13. The cylinder 4 is pushed out, causing the fixing plate 8 to move on the connecting rod 6, thereby driving the first spring 11, the second mounting plate 10, and the second heat-sealing block 13 to move towards the first heat-sealing block 12. The first heat-sealing block 12 and the second heat-sealing block 13 interlock, sealing the film. The cylinder 4 continues to push out, compressing the first spring 11. At this time, the fixing plate 8 continues to drive the second spring 16, the tool fixing block 15, the cutter 17, and the punching knife 18 to move, simultaneously cutting the film and punching holes for hanging bags. This achieves the purpose of integrated operation of sealing, cutting, and punching holes for hanging bags, making the air... As cylinder 4 continues to extend, spring 16 is compressed, and the fixing plate 8 drives the push rod 14 to continue moving. The push rod 14 moves inside the punching knife 18 until it protrudes from the mounting plate 7. The push rod 14 can push out the film residue inside the punching knife 18 or the heat sealing block 12, thus achieving the purpose of pushing out the film residue caused by punching the bag hole. When it is necessary to operate the angled film, pull one of the levers 23, so that the lever 23 drives the pawl 21 to rotate, so that one of the pawls 21 disengages from the gear 20, which can rotate the rotating shaft 2, thereby driving the protective cover 3, connecting rod 6 and fixing plate 8 to rotate, thereby changing the angle between the heat sealing block 12 and the heat sealing block 13, thus achieving the purpose of operating the angled film.
