[0032] EMBODIMENT

[0033] Please refer to Figure 1 , Figure 2、 Figure 3 and Figure 4 As shown in the drawings, the present embodiment provides an auxiliary device for hot pressing magic tape, the magic tape has a fuzzy surface, the fuzzy surface comprises a fluff layer and a base cloth layer which are hot-pressed by hot melt adhesive, and the fluff layer has a plurality of densely arranged fluffs. The auxiliary device comprises a buffer piece 20, a plurality of buffer protrusions 1111 for passing through or pressing the fluffs of the fuzzy surface to form a buffer are arranged on the buffer piece 20, and the buffer piece 20 is used for clamping between a pressing plate and the fuzzy surface (the fluff layer side) of the magic tape to be hot-pressed to buffer, so as to avoid the pressing plate from flattening or collapsing the fluff layer of the fuzzy surface of the magic tape to be hot-pressed.

[0034] Specifically, the pressing plate is a pressing plate in a hot pressing device for hot pressing and bonding the magic tape, and through the design of the buffer piece 20, when the hot press is used to heat and press the fluff layer and the base cloth during production, the buffer piece separates the fuzzy surface of the magic tape and the pressing plate of the hot press. Since the buffer protrusions only locally contact the fuzzy surface and have a small contact area, or the fluffs of the fuzzy surface are filled in the gap to reduce the space for the fluffs to fall around when being pressed, the problem that the fluff layer of the fuzzy surface of the magic tape is flattened or collapsed by the pressing plate can be improved, the fuzzy surface can maintain a certain fluffiness and three-dimensionality after pressing, and the bonding capacity of the fuzzy surface and the hook surface of the magic tape can be improved.

[0035] The buffer protrusions 1111 can be designed of a material with elasticity or flexibility, and can be made of silicone, polyurethane, nylon or polypropylene. The structure can be a columnar structure, a hook-shaped structure or a needle-shaped structure, so that the fluffs of the fuzzy surface are not collapsed during hot pressing when the fuzzy surface is pressed, and the performance of the fuzzy surface is ensured.

[0036] Further, the present embodiment further comprises a placement plate 10 and a pressing plate 11 which is coupled or separated with the placement plate 10, a plurality of buffer protrusions 1111 are arranged on the pressing plate 11 at intervals, and the buffer piece 20 is arranged on the pressing plate 11 (as shown in Figure 2 , or the buffer protrusions 1111 are integrally formed on the pressing plate 11 (as shown in Figure 1 . Alternatively, the buffer protrusions 1111 can be detachably arranged on the pressing plate 11 through the buffer piece 20, so that the buffer protrusions 1111 can be replaced after being damaged, without replacing the entire pressing plate 11, which can effectively save the use cost and prolong the service life of the auxiliary device for hot pressing magic tape.

[0037] And the setting plate 10 is provided with a mark and / or a limiting position magic paste positioning part 101 (the positioning part 101 is specifically used for placing the base cloth and the pile layer to be hot-pressed to form the pile surface), the top pressing plate 11 is provided with a clamping part 112 matched with the positioning part 101, the positioning part 101 and the clamping part 112 are matched with each other to avoid the deviation of the top pressing plate 11 and the positioning part 101, so as to ensure that the buffer protrusion 1111 can accurately press the base cloth and the pile layer, and ensure the effect of hot-pressing.

[0038] In actual operation, the setting plate 10 and the top pressing plate 11 can be separate independent structures, and the connecting surface of the pile layer and the base cloth is also provided with a hot melt film for bonding. First, the base cloth and the pile layer are placed on the positioning part 101 of the setting plate 10, and then the setting plate 10 is matched with the top pressing plate 11 to clamp and fix the base cloth and the pile layer, the hot-pressing production magic paste auxiliary device is put into the hot-pressing machine, and the upper die and the lower die of the hot-pressing machine clamp the hot-pressing production magic paste auxiliary device for hot-pressing. When hot-pressing, the heating temperature of the upper die of the hot-pressing machine is 230℃±5℃, the heating temperature of the lower die is 130℃±5℃, the pressure value is 40KG, and the heating time is 40s, so as to realize the hot melt connection of the base cloth and the pile layer to form the pile surface of the magic paste. At the same time, the base cloth and the pile layer are pressed by the buffer protrusion 1111, which can reduce the contact area and avoid the situation that the contact surface is too large to flatten the pile surface, so as to ensure that the pile surface maintains a certain elasticity and stereoscopic feeling after pressing, and then improve the bonding capacity of the pile surface and the hook surface of the magic paste.

[0039] As shown in Figure 1 The buffer protrusion 1111 is a columnar structure, a hook-shaped structure or a needle-shaped structure, and the buffer protrusions 1111 are uniformly and spacedly arranged to form a rectangular array structure, so that the pressing is more uniform. Compared with plane pressing, the columnar structure, the hook-shaped structure or the needle-shaped structure of the buffer protrusion 1111 only contacts the pile surface of the magic paste locally, realizes point or local pressing, reduces the contact area, and thus can ensure the stereoscopic form of the pile surface after pressing.

[0040] In a preferred embodiment, the buffer protrusion 1111 is a columnar structure with a diameter of 1mm-3mm, preferably a diameter of 2mm. The diameter and distribution density of the buffer protrusion 1111 can be adjusted according to the actual pressing pressure value, which can ensure the bonding strength and reduce the contact area.

[0041] As shown in Figure 2As shown, the positioning part 101 in the embodiment is a groove structure, a positioning column structure, a contour line structure or a magnetic attraction structure. Specifically, the positioning part 101 cooperates with the clamping part 112, which can quickly align the positions of the storage plate 10 and the top pressing plate 11, and can realize stable connection of the storage plate 10 and the top pressing plate 11 through the connection of the positioning part 101 and the clamping part 112, avoiding displacement during processing.

[0042] As shown in Figure 2 , Figure 3 and Figure 4 , the storage plate 10 and the top pressing plate 11 in the embodiment are provided with at least one hinge 12 on one side for opening or stacking. Specifically, the hinge 12 is connected to one side of the storage plate 10 and the top pressing plate 11 in the embodiment, and the pressing can be completed by simply opening and closing, which is more convenient to operate. In addition, the design of the hinge 12 makes the storage plate 10 and the top pressing plate 11 move along a specific trajectory, ensuring that the positions of the storage plate 10 and the top pressing plate 11 are accurately aligned during pressing, avoiding misalignment or deviation.

[0043] In a preferred embodiment, a rotating shaft (not shown in the figure) is arranged on one side of the storage plate 10 and the top pressing plate 11, the hinge 12 is arranged on the rotating shaft, a torsional spring (not shown in the figure) is arranged on the rotating shaft, one end of the torsional spring extends outward to form a first force arm (not shown in the figure) pressing on one side of the hinge 12, and the other end of the torsional spring extends outward to form a second force arm (not shown in the figure) pressing on the other side of the hinge 12. In this way, when manually closing or separating the storage plate 10 and the top pressing plate 11, the torsional spring is twisted and stores elastic potential energy, and after the applied force is released, the torsional spring converts the stored elastic potential energy into torque, so that the hinge 12 drives the storage plate 10 and the top pressing plate 11 to automatically separate or close, which is more convenient to operate.

[0044] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
