[0001] This utility model relates to the field of heat sealing and cutting technology, specifically to a heat sealing and cutting device for a heat pressing cutting machine. Background Technology

[0002] A hot press cutting machine is a processing machine used in industrial production to cut various flexible materials. Its main function is to use a forming die to obtain the required sheets or semi-finished products through a cutting action. Currently, in the production process of packaging bags, a hot press sealing and cutting device is needed to heat-seal and cut the folded packaging bag material, cutting the packaging bag material into fixed-length packaging bags while sealing the ends of the packaging bags.

[0003] After prolonged use, existing hot-press sealing and cutting devices leave adhesive residue on the blade surface of the heat-sealing knife, requiring manual cleaning, which is time-consuming, labor-intensive, and reduces work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a hot-press edge sealing and cutting device for a hot-press cutting machine. Utility Model Content

[0005] The purpose of this utility model is to provide a hot-press edge sealing and cutting device for a hot-press cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-pressing edge-sealing cutting device for a hot-pressing cutting machine, comprising a frame and a hot-sealing knife. Support plates are fixed to the upper sides of both sides of the frame, and guide columns are connected to the bottom of the support plates. Springs are sleeved on the outside of the guide columns, and a movable seat is connected to the bottom of the springs. Roller frames are provided on both sides of the top of the movable seat, and rollers are connected to the roller frames via axles. A connecting rod is hinged to the bottom of the movable seat, and a slider is hinged to the other end of the connecting rod. A sliding rod passes through the middle of the slider, and knife holders are fixed to both ends of the sliding rod. The hot-sealing knife is located at the bottom of the knife holder. A servo motor is installed on the lower right side of the frame, and a lead screw is connected to the output end of the servo motor. A lead screw nut is connected to the outside of the lead screw, and a cleaning brush is provided at the outer front end of the lead screw nut.

[0007] Furthermore, a drive motor is provided on the upper right side of the frame, and a drive rod is connected to the output end of the drive motor. A cam is fixedly fitted onto the outside of the drive rod.

[0008] Furthermore, the cam and the roller are closely fitted together, and there are two of each type of cam and roller.

[0009] Furthermore, the end of the spring away from the movable seat is fixedly connected to the support plate, and the side of the movable seat has an inverted concave structure.

[0010] Furthermore, a buffer spring is sleeved on the outside of the slide rod, and a damping plate is provided at the end of the buffer spring away from the slide block.

[0011] Furthermore, T-shaped guide rods are fixed on both sides of the bottom of the movable seat, and damping plates are provided at the bottom of the T-shaped guide rods.

[0012] Furthermore, a second buffer spring is provided below the second damping plate, and a third damping plate is provided below the second buffer spring.

[0013] Furthermore, the drive rod and the lead screw are parallel to each other, and the internal structure of the cleaning brush matches the external structure of the heat sealing knife.

[0014] This utility model provides a hot-press edge-sealing and cutting device for a hot-press cutting machine, which has the following beneficial effects:

[0015] 1. The drive rod and cam of this utility model rotate under the drive of the drive motor.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a hot-pressing edge-sealing cutting device for a hot-pressing cutting machine includes a frame 1 and a hot-sealing knife 18. Support plates 5 are fixed to the upper sides of both sides inside the frame 1, and guide columns 6 are connected to the bottom of the support plates 5. Springs 7 are sleeved on the outside of the guide columns 6, and a movable seat 8 is connected to the bottom of the springs 7. Roller frames 9 are arranged on both sides of the top of the movable seat 8, and rollers 11 are connected to the roller frames 9 via axles 10. A connecting rod 12 is hinged to the bottom of the movable seat 8, and a slider 13 is hinged to the other end of the connecting rod 12. A sliding rod 14 passes through the middle of the slider 13, and knife holders 17 are fixed to both ends of the sliding rod 14. The hot-sealing knife 18 is located at the bottom of the knife holder 17. A drive motor is arranged on the upper right side of the frame 1. 2. The output end of the drive motor 2 is connected to the drive rod 3. The drive rod 3 is fitted with a cam 4. The cam 4 and the roller 11 are closely fitted. There are two cams and two rollers 11. The end of the spring 7 away from the moving seat 8 is fixedly connected to the support plate 5. The side of the moving seat 8 has an inverted concave structure. The slide rod 14 is fitted with a buffer spring 15. The end of the buffer spring 15 away from the slider 13 is provided with a damping plate 16. T-shaped guide rods 19 are fixed on both sides of the bottom of the moving seat 8. The bottom of the T-shaped guide rod 19 is provided with a damping plate 20. The bottom of the damping plate 20 is provided with a buffer spring 21. The bottom of the buffer spring 21 is provided with a damping plate 3 22.

[0023] The specific operation is as follows: the drive rod 3 and cam 4 rotate under the drive of the drive motor 2. The convex part of cam 4 contacts the roller 11, which allows the moving seat 8 to overcome the spring 7 and make longitudinal displacement. Thus, the heat sealing knife 18 cuts and seals the packaging bag material. The whole action is carried out by the concave part of cam 4 rotating to the convex part in a stable manner, avoiding excessive force that could damage the packaging bag material.

[0024] like Figure 1As shown, a servo motor 23 is installed on the lower right side of the frame 1, and a lead screw 24 is connected to the output end of the servo motor 23. A lead screw nut 25 is connected to the outside of the lead screw 24, and a cleaning brush 26 is provided at the front end of the lead screw nut 25. The drive rod 3 and the lead screw 24 are parallel to each other, and the internal structure of the cleaning brush 26 matches the external structure of the heat sealing knife 18.

[0025] The specific operation is as follows: the lead screw 24 is set at the lower rear end of the heat sealing knife 18. The lead screw 24 is driven to rotate by the servo motor 23, so that the cleaning brush 26 follows the lead screw nut 25 to move laterally along the outside of the lead screw 24, thereby cleaning the adhesive residue on the heat sealing knife 18, keeping the heat sealing knife 18 smooth and clean, and preventing foreign objects on the heat sealing knife 18 from affecting the heat sealing effect.

[0026] In summary, when the hot-pressing edge-sealing cutting device of this hot-pressing cutting machine is in use, the drive motor 2 is started when the outer feeding roll passes under the heat-sealing knife 18. The drive motor 2 drives the drive rod 3 and cam 4 to rotate, so that the roller 11 is affected by the concave part of the cam 4 turning into the convex part, which helps the moving seat 8 to overcome the spring 7 rebound and move longitudinally along the outside of the guide column 6. When the heat-sealing knife 18 presses on the packaging bag material, it cuts and seals the packaging bag material.

[0027] During the process, when the heat sealing knife 18 is subjected to a large impact force, it will move upward, causing the angle of the connecting rod 12 to change slowly, and driving the slider 13 to move outside the slider 14 to compress the buffer spring 15. The T-shaped guide rod 19 drives the damping plate 20 to move downward to compress the buffer spring 21. Under the damping action of the damping plate 16, the damping plate 20, and the damping plate 32, the heat sealing knife 18 has a good buffering effect, reducing the damage to the heat sealing knife 18 and the frame 1.

[0028] Subsequently, the cam 4 changes from a convex part to a concave part and contacts the roller 11. The unsupported moving seat 8 relies on the rebound force of the spring 7 to drive the heat sealing knife 18 away from the packaging bag material. Since the heat sealing knife 18 is withdrawn as a continuous action, the force on the packaging bag material is reduced, thus avoiding damage to the packaging bag material.

[0029] When it is necessary to clean the heat sealing knife 18, the servo motor 23 can be started, which drives the lead screw 24 to rotate, so that the cleaning brush 26 follows the lead screw nut 25 to move laterally along the outside of the lead screw 24, thereby cleaning the residual adhesive on the heat sealing knife 18, keeping the heat sealing knife 18 smooth and clean, and preventing foreign objects on the heat sealing knife 18 from affecting the heat sealing effect.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
