Description

Technical Field

[0001] The utility model relates to the technical field of heat-sealing film processing, in particular to an automatic heat-sealing film slitting device. Background Art

[0002] Heat-sealed film is also called hot-melt adhesive film. Hot-melt adhesive film is a film product with or without release paper. It can be easily operated continuously or intermittently, and can be widely used for bonding various fabrics, papers, polymer materials and metals. In the processing of hot-melt adhesive film, it is necessary to cut the hot-melt adhesive film through an automatic cutting device. Most of the existing cutting devices have a simple structure and need to be used manually. The cutting efficiency of the hot-melt adhesive film is low, which is inconvenient for people to use, and it is not convenient to transport the hot-melt adhesive film. The cutting effect of the hot-melt adhesive film is poor and the practicality is low.

[0003] In order to solve the above problems, publication number CN202220045871.5 discloses “a hot-melt adhesive film automatic cutting device” which drives the adjusting rod to rotate through a motor, and the external thread on the outside of the adjusting rod cooperates with the threaded hole inside the movable block, so that the movable block can drive the cutting knife to move left and right, thereby realizing the cutting of the hot-melt adhesive film, and drives the rotating shaft to rotate through a reduction motor, and the rotating rotating shaft drives the rotating roller to rotate, and the rotating rotating roller drives the material roller to rotate, so as to facilitate the conveying of the hot-melt adhesive film. However, in actual use, there are still some problems. The adjusting rod is driven by the reaction force of the thread engagement to drive the cutting knife to move, and the forward and reverse rotation of the motor is used to control the cutting knife to move left and right. However, the efficiency of the thread engagement to drive the cutting knife to move is low, which makes the cutting speed slow and affects the processing efficiency. At the same time, the height position of the conveying roller of this device is fixed. When cutting hot-melt adhesive films of different thicknesses, the conveying roller of thicker hot-melt adhesive films will squeeze them, causing the hot-melt adhesive film to deform under internal pressure. If it is a thinner hot-melt adhesive film, the conveying roller cannot contact and rub with the hot-melt adhesive film, and thus the hot-melt adhesive film cannot be conveyed to move, so the practicability is poor.

[0025] The automatic heat-sealing film slitting device is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Example 1

[0028] See also Figure 1-7 In the embodiment, an automatic heat-sealing film slitting device is provided, comprising: a processing table 1, a loading rack 11 is provided on the top of the processing table 1, a gantry 12 is provided on one side of the loading rack 11, a feeding roller 13 is provided under the gantry 12, a mounting frame 14 is provided on one side of the gantry 12, a cutter 15 is provided inside the mounting frame 14, a cutting component is provided inside the mounting frame 14, and is used to quickly cut the heat-sealed film, and an adjusting component is provided on the gantry 12, and is used to adjust the height of the feeding roller 13.

[0029] Among them, two fixed blocks 5 are arranged on one side of the loading rack 11, and limiting grooves 51 are respectively opened on the opposite sides of the two fixed blocks 5. One side of the two limiting grooves 51 is rotatably connected to a pressure rod 52, and a pressure roller 53 is rotatably connected between the two pressure rods 52.

[0030] When in use, the heat-sealed film roll is installed on the loading rack 11, and the heat-sealed film roll is pulled out and passed through the feed roller 13 and the bottom of the installation frame 14 respectively, so as to complete the loading of the heat-sealed film roll. Before cutting, the two pressure rods 52 are rotated clockwise to allow the pressure roller 53 to be placed on the heat-sealed film roll. The setting of the limiting groove 51 limits the counterclockwise rotation degree of the pressure rod 52.

[0031] Example 2

[0032] On the basis of Example 1, the cutting assembly includes: two rollers 2 rotatably connected to the inside of the mounting frame 14, a belt 21 is connected between the two rollers 2, four connecting blocks 22 are fixedly connected to the belt 21, the four connecting blocks 22 are rotatably connected to the inside of each of the four connecting blocks 22, the two rotating rods 23 on the same side are respectively rotatably connected to the opposite sides of the outside of the cutter 15, a driving motor a24 fixedly installed on one side of the mounting frame 14, one end of the driving shaft of the driving motor a24 is connected to one of the rollers 2, symmetrically arranged guide grooves 25 are respectively opened on the opposite sides of the inner wall of the mounting frame 14, the cutter 15 is fixedly connected to the axial position on the opposite sides with mounting rods 26, the outside of the mounting rods 26 are respectively rotatably connected to rollers 27, and the rollers 27 are respectively slidably connected in the guide grooves 25.

[0033] During cutting, the connected rollers 2 are driven to rotate by the driving motor a24, and the two rollers 2 cooperate with each other to drive the belt 21 to move. When the belt 21 moves, it drives the four connecting blocks 22 at the bottom to move at the same time. The connecting block 22 drives the cutter 15 to move through the rotating rod 23. When the cutter 15 moves, it drives the mounting rod 26 to move, and the mounting rod 26 drives the roller 27 to move in the guide groove 25, so as to limit and guide the moving trajectory of the cutter 15 to avoid the cutter 15 shaking and causing deviation during cutting. In this way, the cutter 15 is driven to move quickly by the moving belt 21, and the moving cutter 15 can cut the heat-sealed film. The cutter 15 is initially located at the position of the roller 2. After the belt 21 rotates one circle, it returns to the initial position, and the driving motor a24 stops working, so that the heat-sealed film can be cut quickly.

[0036] The height of the feeding roller 13 is adjusted according to the actual thickness of the heat-sealed film. During adjustment, the handle 31 is manually rotated to drive the threaded rod 3 to screw into the threaded hole, which will drive the threaded rod 3 to move, and the threaded rod 3 drives the mounting frame 32 to move. When the mounting frame 32 moves, the driving motor b35 and the counterweight block 38 on both sides are driven to move at the same time. The weight of the counterweight block 38 is equal to that of the driving motor b35, so as to avoid the mounting frame 32 from warping. The threaded rod 3 is controlled to move upward or downward by controlling the rotation direction of the handle 31, and the mounting frame 32 drives the feeding roller 13 to move to achieve the purpose of adjusting the height. After adjustment, the rear driving motor b35 is started to drive the feeding roller 13 to rotate, thereby conveying the heat-sealed film to one side, so that heat-sealed films of different thicknesses can be conveyed. The driving motor b35 stops working after conveying the heat-sealed film to a suitable length, and then the driving motor a24 is started to drive the cutter 15 to cut the heat-sealed film. The driving motor a24 cooperates with the driving motor b35 to convey the heat-sealed film and cut it.
