Description
Technical Field
[0001] This utility model belongs to the field of auxiliary tool technology, specifically relating to a self-protective tape cutting device for packaging machines. Background Technology
[0002] Intelligent packaging machines are a type of machine used to package products. There are many types of intelligent packaging machines, and they can be classified in many ways. By type of machinery, they can be divided into liquid packaging machines, powder packaging machines, granule packaging machines, etc.; by level of automation, they can be divided into semi-automatic packaging machines, fully automatic packaging machines, etc. After packaging the product, the intelligent packaging machine needs to use tape to seal the packaged product to ensure that the contents do not fall out. When sealing, the tape is pulled out, stuck to the area to be sealed, and then cut to seal the next packaged product. Therefore, the tape needs to be cut frequently. Due to the large amount of sealing work, a tape cutting device is usually needed to cut the tape to speed up the work.
[0003] There are various specifications of tapes on the market, including tape cores. Existing tape cutting devices can only accommodate tape cores of one diameter. When using tapes of other specifications, it can lead to situations where the tape cannot be placed or becomes extremely inconvenient to use after placement. In addition, when cutting tape, the tape deforms under external force, so the cutter will lift the tape during cutting, resulting in poor cutting efficiency. To address this, we have proposed a self-protective tape cutting device for packaging machines. Utility Model Content
[0004] The purpose of this invention is to provide a self-protective tape cutting device for packaging machines to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-protective tape cutting device for packaging machines, comprising a fixed frame, a rotating seat rotatably connected to one side of the fixed frame, a lead screw rotatably connected inside the rotating seat, a conical block threadedly connected to the outside of the lead screw, a groove formed on the surface of the conical block, a ball slidably connected within the groove, a support rod fixedly connected to the outside of the ball, the support rod penetrating the outside of the rotating seat, an arc-shaped plate fixedly connected to the outer end face of the support rod, an annular plate threadedly connected to one side of the outside of the rotating seat, a partition plate fixedly connected to the other side of the outside of the rotating seat, and a through hole formed on one side of the fixed frame.
[0006] In a preferred embodiment, a rotating rod is slidably connected inside the fixing frame, and a pressure roller is rotatably connected to one side of the rotating rod. One end of the rotating rod is threaded with a No. 1 bolt, and one side of the rotating rod is fixed to the fixing frame by the No. 1 bolt.
[0007] In a preferred embodiment, a baffle is fixedly connected to the top of the other side of the fixing frame, a first square connecting rod is slidably connected inside the baffle, a first pressing plate is fixedly connected to the top of the first square connecting rod, the first pressing plate and the baffle are fixedly connected by a first spring, and a lower pressing block is fixedly connected to the bottom of the first square connecting rod.
[0008] In a preferred embodiment, a blade guard is fixedly connected to the bottom of the other side of the fixing frame, a blade guard plate is slidably connected to the top of the blade guard, the blade guard plate and the fixing frame are fixedly connected by two magnets, and a base plate is provided at the bottom of the blade guard, with both sides of the base plate fixedly connected to the bottom of the base plate by No. 2 bolts.
[0009] In a preferred embodiment, the lead screw passes through one side of the rotating seat, one end of the lead screw is fixedly connected to a throttle, the number of the sliding grooves is four, and the cross-section of the support rod is square.
[0010] In a preferred embodiment, a second square connecting rod is slidably connected inside the base plate. A mounting plate is fixedly connected to the top of the second square connecting rod. A cutter is provided inside the mounting plate. The cutter is fixed inside the mounting plate by fixing bolts. A second pressing plate is fixedly connected to the bottom of the second square connecting rod. The second pressing plate and the base plate are fixedly connected by a second spring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This packaging machine uses a self-protecting tape cutting device. By setting up a rotating seat, lead screw, conical block, ball bearing, and arc plate, the lead screw can be rotated by turning the throttle, which causes the conical block to move left and right, and the ball bearing to move in the slide groove, which in turn causes the support rod and arc plate to move up and down. This allows for the placement of tapes of different specifications, avoiding the situation where it is impossible to place or extremely inconvenient to use tapes of different specifications.
[0013] 2. This packaging machine uses a self-protecting tape cutting device. By setting up a first pressing plate, a first spring, a lower pressing block, a second pressing plate, a second spring, and a cutter, pressure can be applied to the first and second pressing plates simultaneously when tape needs to be cut. This causes the lower pressing block and the cutter to move towards the tape. The lower pressing block can prevent the tape from deforming due to force and rising during cutting, thus facilitating tape cutting. Attached Figure Description

[0024] Please see Figures 1-7This utility model provides a self-protective tape cutting device for packaging machines, including a fixed frame 1. A rotating seat 2 is rotatably connected to one side of the fixed frame 1. To accommodate the installation of tape cores of different diameters and facilitate tape pulling, a lead screw 3 is rotatably connected inside the rotating seat 2. A conical block 4 is threadedly connected to the outside of the lead screw 3. A groove is formed on the surface of the conical block 4, and a ball 5 is slidably connected inside the groove. A support rod 6 is fixedly connected to the outside of the ball 5. The support rod 6 passes through the outside of the rotating seat 2, and an arc-shaped plate 7 is fixedly connected to the outer end face of the support rod 6. An annular plate 8 is threadedly connected to one side of the outside of the rotating seat 2, and a partition plate 9 is fixedly connected to the other side of the outside of the rotating seat 2. A through hole is formed on one side of the fixed frame 1, through which the lead screw 3 passes. A handle 29 is fixedly connected to one end of the lead screw 3. A rotating rod 10 is slidably connected inside the fixed frame 1. A pressure roller 11 is rotatably connected to the rotating rod 10. One end of the rotating rod 10 is threaded with a bolt 12. One side of the rotating rod 10 is fixed to the fixed frame 1 by the bolt 12. When the intelligent packaging machine has packaged the product and needs to seal it, the tape is placed on the rotating seat 2. The handle 29 is rotated, which drives the lead screw 3 to rotate, thereby driving the conical block 4 to move left and right. The ball 5 moves in the groove, thereby driving the support rod 6 and the arc plate 7 to move up and down. This allows tape cores of different diameters to be placed. The ring plate 8 is screwed onto the rotating seat 2 to prevent the tape from accidentally falling off. The rotating rod 10 is moved to a suitable position and fixed to the fixed frame 1 by the bolt 12. Under the action of the pressure roller 11, the tape can be pulled out horizontally and stuck to the packaging that needs to be sealed, thus achieving the purpose of adapting to the installation of tape cores of different diameters and facilitating the pulling out of the tape.
[0025] Please see Figure 1 , Figure 6 and Figure 7To cut and protect the tape, a baffle 13 is fixedly connected to the top of the other side of the fixing frame 1. A square connecting rod 14 is slidably connected inside the baffle 13. A pressing plate 15 is fixedly connected to the top of the square connecting rod 14. The pressing plate 15 and the baffle 13 are fixedly connected by a spring 16. A pressing block 17 is fixedly connected to the bottom of the square connecting rod 14. A blade guard 18 is fixedly connected to the bottom of the other side of the fixing frame 1. A blade guard plate 19 is slidably connected to the top of the blade guard 18. The blade guard plate 19 and the fixing frame 1 are fixedly connected by two magnets 20. A base plate 21 is provided at the bottom of the blade guard 18. Both sides of the base plate 21 are fixedly connected to the bottom of the base plate 21 by bolts 22. A square connecting rod 23 is slidably connected inside the base plate 21. A mounting plate 24 is fixedly connected to the top of the square connecting rod 23. A cutter 25 is provided inside the mounting plate 24. The cutter 25 is fixed inside the mounting plate 24 by fixing bolts 26. The bottom of the second square connecting rod 23 is fixedly connected to the second pressing plate 27. The second pressing plate 27 and the base plate 21 are fixedly connected by the second spring 28. When it is necessary to cut the tape, pressure is applied to the first pressing plate 15 and the second pressing plate 27 simultaneously with two fingers of one hand. The first pressing plate 15 drives the first square connecting rod 14 and the lower pressure block 17 to descend, limiting the tape. To prevent the tape from rising, the second pressing plate 27 drives the second square connecting rod 23, the mounting plate 24, and the cutter 25 to rise. The cutter 25 cuts the tape. After cutting, the first pressing plate 15 and the second pressing plate 27 are released. Under the action of the first spring 16 and the second spring 28, the lower pressing block 17 and the cutter 25 return to their original positions. The cutter 25 is hidden in the cavity formed by the blade guard plate 19 and the blade guard frame 18, thereby achieving the purpose of cutting the tape and protecting it.
[0026] The working principle and usage process of this utility model are as follows: After the intelligent packaging machine has packaged the product, when sealing is required, first place the tape on the rotating seat 2, rotate the handle 29, which drives the lead screw 3 to rotate, thereby causing the conical block 4 to move left and right, and the ball 5 to move in the groove, thereby causing the ball 5 to drive the support rod 6 and the arc plate 7 to move up and down, thus allowing the installation of tape cores of different diameters. Screw the ring plate 8 onto the rotating seat 2 to prevent the tape from accidentally falling off. Move the rotating rod 10 to the appropriate position and fix the rotating rod 10 to the fixing frame 1 with the No. 1 bolt 12. Under the action of the pressure roller 11, the tape can be pulled out horizontally and stuck to the packaging that needs to be sealed, thus achieving the installation of tape cores of different diameters. The purpose of the tape is to facilitate its pull-out. When the tape needs to be cut, pressure is applied simultaneously to the first pressing plate 15 and the second pressing plate 27 with two fingers of one hand. The first pressing plate 15 drives the first square connecting rod 14 and the lower pressing block 17 to descend, limiting the tape and preventing it from rising. The second pressing plate 27 drives the second square connecting rod 23, the mounting plate 24, and the cutter 25 to rise. The cutter 25 cuts the tape. After cutting, the first pressing plate 15 and the second pressing plate 27 are released. Under the action of the first spring 16 and the second spring 28, the lower pressing block 17 and the cutter 25 return to their original positions. The cutter 25 is hidden in the cavity formed by the blade guard plate 19 and the blade guard frame 18, thus achieving the purpose of cutting the tape and providing protection.
