Technical Field

[0001] The utility model relates to the technical field of foam processing, in particular to a device for preventing an adhesive tape from sticking to a mold for foam processing. Background Art

[0002] There are many types of foam. Different types of foam are widely used in electronic products, automotive interiors, architectural decoration, sports and leisure, and medical fields according to their characteristics and uses. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy use, easy bending, ultra-thin volume, and reliable performance.

[0003] For example, the Chinese utility model patent (CN 219170988 U) relates to the field of foam processing technology, and discloses a device for preventing adhesive tape from sticking to a mold for foam processing, including a mold plate, one side of the bottom surface of the mold plate is fixedly connected to the top of the cutter, a cutting groove is provided on one side of the middle of the pressure plate, and a cleaning mechanism is provided on both sides of the inner wall of the cutting groove; the cleaning mechanism includes a scraper, a support rod, a first spring, and a push rod, the top of the scraper is rotatably connected to the top of one side of the middle of the pressure plate, the other end of the first spring is fixedly connected to the bottom of the push rod, the outer side of the bottom of the push rod is slidably connected to the middle of one side of the support rod, and the top of the push rod is rotatably connected to the middle of one side of the scraper. In the utility model, the first spring is compressed, and when the cutter is retracted, the elastic force of the spring can be used to lift the two scrapers to make them close to the two sides of the cutter, so that the cutter can be cleaned when the cutter is retracted to avoid the inconvenience of retracting the cutter.

[0004] However, in the above patent, the foam will adhere to the outer wall of the cutter when being cut, so that the foam as a whole is moved by the cutter, resulting in changes in the position of the foam, which requires manual correction and affects subsequent processing. In addition, a scraper is used to remove debris from the outer wall of the cutter, but the cutter cannot be guaranteed to be parallel to the foam. The scraper is integrated, which easily causes one side of the cutter to be unable to be cleaned, resulting in poor cleaning effect. In addition, the structure supporting the scraper is complicated and difficult to replace and disassemble. Therefore, a device is needed to prevent the tape from sticking to the mold for foam processing. Utility Model Content

[0025] like Figure 1-4 As shown, a device for preventing a tape from sticking to a mold for foam processing includes a cutting knife 1 and a buffer mechanism arranged outside the cutting knife 1, wherein the buffer mechanism includes a working component and a buffer component;

[0026] The working assembly includes a force-bearing plate 2, the outside of the cutting knife 1 is provided with the force-bearing plate 2, the bottom of the force-bearing plate 2 is fixedly connected with a sliding column 3, and the outer wall of the sliding column 3 is slidably connected with a hollow column 4;

[0027] The buffer assembly includes a first spring 5, the outer wall of the hollow column 4 is provided with the first spring 5, the bottom end of the hollow column 4 is fixedly connected to the bottom plate 6, the bottom of the force-bearing plate 2 is fixedly connected to the fixed column 7, the bottom end of the fixed column 7 is rotatably connected to the connecting rod 8, one end of the connecting rod 8 is rotatably connected to the sliding ring 9, the inner wall of the sliding ring 9 is slidably connected to the connecting column 10, and the outer wall of the connecting column 10 is provided with a second spring 11.

[0028] Among them, Figure 3 As shown, the hollow column 4 is provided with a sliding groove that matches the sliding column 3. The sliding column 3 forms a buffer structure with the hollow column 4 through the force-bearing plate 2 and the first spring 5, which is conducive to the sliding column 3 shrinking into the groove of the hollow column 4. The first spring 5 plays an elastic support effect, so that there is a certain elastic force between the pre-load plate 16 and the top plate 18.

[0029] Among them, Figure 3 As shown, the sliding ring 9 is provided with a sliding groove which matches the connecting column 10. The sliding ring 9 forms a sliding structure with the connecting column 10 through the connecting rod 8, which is conducive to the fixed column 7 driving the connecting rod 8 to move, pushing the sliding ring 9 to slide on the outer wall of the connecting column 10, playing a lateral buffering effect and providing a pre-compression support force.

[0030] Among them, Figure 2 As shown, two groups of force-bearing plates 2, sliding columns 3, hollow columns 4, first springs 5, base plates 6, fixed columns 7 and connecting rods 8 are provided. The position relationship of the two groups of force-bearing plates 2, sliding columns 3, hollow columns 4, first springs 5, base plates 6, fixed columns 7 and connecting rods 8 is symmetrically distributed about the central axis of the cutting knife 1, which is beneficial to ensure the stability of the pre-stressing of the pre-stressing plate 16 and prevent the occurrence of uneven force.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4As shown, this embodiment further illustrates Example 1, an extrusion block 12 is provided at the bottom of the cutting knife 1, a push column 13 is fixedly connected to one side of the extrusion block 12, a third spring 14 is fixedly connected to one end of the push column 13, the outer wall of the push column 13 is slidably connected to a limiting column 15, the outer wall of the extrusion block 12 is slidably connected to a pre-load plate 16, the outer wall of the pre-load plate 16 is fixedly connected to a support plate 17, and the top of the cutting knife 1 is fixedly connected to a top plate 18.

[0033] Among them, Figure 4 As shown, the pre-pressing plate 16 is provided with a sliding groove that matches the extrusion block 12. The extrusion block 12 forms a sliding structure with the pre-pressing plate 16 through the pushing column 13, which is conducive to the extrusion block 12 sliding in the groove of the pre-pressing plate 16, so that the extrusion block 12 can remove the debris adhered to the cutting knife 1.

[0034] Among them, Figure 1 As shown, six groups of extrusion blocks 12, push columns 13, third springs 14 and limit columns 15 are provided. The positional relationship of the six groups of extrusion blocks 12, push columns 13, third springs 14 and limit columns 15 is equidistantly arranged with respect to the outer wall of the support plate 17, which is beneficial to ensure that the outer wall of the cutting knife 1 is subjected to balanced pressure, making it convenient to remove debris.

[0035] When in use: First, when the cutting knife 1 moves downward to perform the cutting operation, the force-bearing plate 2 drives the sliding column 3 to move downward and slide on the outer wall of the hollow column 4. The first spring 5 plays the role of elastic support, which enables the bottom plate 6 to drive the pre-pressing plate 16 to first press the material to prevent deviation during cutting. At the same time, the fixed column 7 will also move downward, so that the connecting rod 8 pushes the sliding ring 9 to slide on the outer wall of the connecting column 10. The second spring 11 plays the role of elastic support to prevent the material from adhering to the outer wall of the cutting knife 1 during contraction. As the cutting knife 1 rises, it will also move upward to ensure stability during cutting processing;

[0036] Finally, after the cutting work is completed by the cutting knife 1, it moves downward, and the extrusion block 12 will be in close contact with the outer wall of the cutting knife 1, so that the extrusion block 12 drives the pushing column 13 to shrink into the groove of the limiting column 15, and relies on the third spring 14 to play the role of elastic support, which can further remove the material adhered to the outer wall of the extrusion block 12 to prevent adhesion.
