[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] like Figures 1 to 4 As shown, the utility model provides a multi-layer structure foam forming device 100, which includes a processing table 10, a laminating assembly 20 and a cutting assembly 30, wherein the laminating assembly 20 and the cutting assembly 30 are both mounted on the processing table 10 and arranged on the left and right. It can be understood that the utility model also has a driving transmission structure such as a motor, which is a conventional technology in the technical field and is not described in detail.
[0016] The laminating assembly 20 includes a laminating frame 21, multiple sets of laminating lower rollers 22 and laminating upper rollers 23. The laminating frame 21 stands on the processing table 10. Multiple sets of laminating lower rollers 22 are respectively mounted on the lower part of the laminating frame 21. Multiple sets of laminating upper rollers 23 are respectively mounted on the upper part of the laminating frame 21 and are located above the multiple sets of laminating lower rollers 22. The laminating upper roller 23 includes a roller body 231 and a foam sleeve 232. The foam sleeve 232 is sleeved on the roller body 231, and the outer side of the foam sleeve 232 protrudes from the outer surface of the roller body 231.
[0017] The laminating assembly 20 with multiple laminating rollers can laminat multiple layers of foam material at one time, so that it can be formed into a multi-layer composite foam product at one time without multiple cutting and laminating, which not only saves time and effort, but also reduces the problem of misalignment during the laminating process. The foam ring 232 added to the laminating upper roller 23 can separate the foam material from the roller surface, effectively improving the problem of adhesion between the foam material and the laminating roller and affecting the laminating quality.
[0018] The laminating frame 21 includes a frame body 211, a lifting plate 212 and an adjusting screw 213. The frame body 211 is provided with a lifting groove 211a, the lifting plate 212 is mounted in the lifting groove 211a and can be lifted and lowered, the adjusting screw 213 is screwed in the lifting groove 211a from top to bottom, and the lower end of the adjusting screw 213 is movably connected to the lifting plate 212. The two ends of the laminating upper roller 23 are respectively mounted on the lifting plate 212. The movably adjustable laminating component 20 can adapt to the laminating of foam materials of different thicknesses, ensuring that the composite multi-layer foam product after laminating will not be deformed and damaged due to excessive pressure, and can be firmly laminating to reduce the risk of loosening between layers.
[0019] The cutting assembly 30 includes a cutting frame 31 , a cutting lower roller 32 and a circular knife roller 33 . The cutting frame 31 stands on the processing table 10 . The cutting lower roller 32 and the circular knife roller 33 are respectively mounted on the cutting frame 31 , and the circular knife roller 33 is located above the cutting lower roller 32 .
[0020] The circular knife roller 33 includes an outer roller 331, an inner roller frame 332, a movable roller strip 333, a plurality of blades 334 and a locking spring 335. The outer roller 331 is designed as a hollow cylinder with openings at both ends, and a plurality of locking holes 331a are provided on its side. The inner roller frame 332 is inserted into the outer roller 331. The movable roller strip 333 is designed as a hollow cylinder with openings at one end, and is inserted into the outer roller 331 and sleeved outside the inner roller frame 332. A plurality of adjustment grooves 333a are provided on the outer side surface of the movable roller strip 333. A plurality of blades 334 are inserted from the inside to the outside on the locking holes 331a of the outer roller 331 and can be flexibly extended and retracted, and their inner ends abut against the adjustment grooves 333a of the movable roller strip 333. A plurality of locking springs 335 are respectively inserted on the plurality of blades 334.
[0021] When a composite multi-layer foam product with a specific structure is needed, it is only necessary to select the corresponding movable roller strip 333 and insert it into the circular knife roller 33. The adjustment grooves 333a of different depths on the movable roller strip 333 will form abutment against the inner side end of the blade 334, so that the length of the blade 334 extending out of the outer roller 331 is also different. The blades 334 of different lengths can cut different layers of the foam product during the circular knife cutting, so that it can be formed into the final multi-layer foam product. When it is necessary to cut foam products with different structures, it is only necessary to replace different movable roller strips 333 without disassembling the entire circular knife roller 33.
[0022] Specifically, in this embodiment, the open end of the movable roller strip 333 is designed with a conical curved surface structure. The movable roller strip 333 with a conical curved surface structure at the end is easier to insert between the outer roller 331 and the inner roller frame 332. The inner end of the blade 334 is designed with a convex spherical surface structure, and the two ends of the corresponding adjustment groove 333a are designed with a concave spherical surface structure. The convex spherical surface structure at the end of the blade 334 and the concave spherical surface structure at the end of the adjustment groove 333a can reduce the limiting obstruction between the end of the blade 334 and the adjustment groove 333a, making it easier to insert or withdraw the movable roller strip 333.
[0023] In summary, the beneficial effects of the multi-layered foam molding device 100 of the utility model are: by adding a foam ring sleeve 232 to the bonding roller, the interlayer material of the foam product is not in close contact with the roller surface during the transmission process, which can effectively avoid the problem of the interlayer material sticking to the bonding roller during bonding and affecting the bonding quality; the adjustable circular knife roller 33 is designed, and the movable roller bar 333 is used to adjust the top of the blade 334, so that the blade 334 on the circular knife roller 33 can cut to different layers of the foam product, and finally realize the processing and molding of the multi-layered foam product, which not only makes the processing and molding of the multi-layered foam product easier, but also the molding device can match the processing of foam products of various levels, which greatly expands the scope of application of the molding device; the utility model is highly practical and has a strong promotion significance.
[0024] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
