Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive film processing technology, and in particular to a hot melt adhesive film pressing device. Background Technology

[0002] Hot melt adhesive film is a type of film product with release paper or no release paper as the base material, which bonds materials such as fabrics, metals, and plastics through hot pressing. Hot melt adhesive film is widely used in clothing and footwear materials, industrial manufacturing, and decoration and packaging. During processing, hot melt adhesive film needs to be pressed and bonded to the base material, thus requiring specialized pressing equipment.

[0003] Existing hot melt adhesive film pressing devices typically involve first placing and flattening the fabric, then placing the hot melt adhesive film on the fabric surface, and finally driving a hot press head vertically downwards to achieve the pressing purpose, as illustrated by the existing hot melt adhesive film pressing device with patent publication number CN219650779U. Because these devices lack an integrated structure that automatically straightens and flattens the fabric during the vertical movement of the hot press head, the number of steps involved in the pressing process is increased, thus reducing the pressing efficiency of the hot melt adhesive film. Therefore, we provide a hot melt adhesive film pressing device. Utility Model Content

[0004] To address the problem of low pressing efficiency of hot melt adhesive films in the aforementioned background technology, this utility model provides a hot melt adhesive film pressing device.

[0005] This utility model is achieved by the following technical solution: a hot melt adhesive film pressing device, including a hot pressing table and a leveling component. A bracket is fixedly connected to the hot pressing table, a hydraulic cylinder is fixedly connected to the bracket, a connecting plate is fixedly connected to the telescopic end of the hydraulic cylinder, and a hot pressing head is fixedly connected to the bottom of the connecting plate.

[0006] The leveling assembly includes four sets of movable rods symmetrically slidably connected to the hot press table. The top ends of the two sets of movable rods on the same side are fixedly connected to the same top plate, and the bottom ends of the two sets of movable rods on the same side are fixedly connected to the same bottom plate. A spring is sleeved on the outside of each movable rod. Two sets of connecting rods are symmetrically hinged to the bottom of the top plate. A pressure roller is rotatably connected between the ends of the two sets of connecting rods on the same side. Two sets of strip plates are symmetrically fixedly connected to one side of the top plate. A sliding rod is fixedly connected to the bottom of each strip plate through a connecting seat. The same sliding plate is slidably connected to the outside of the two sets of sliding rods on the same side. A connecting rod is hinged between the sliding plate and the connecting rod 1 through a hinge. A spring is sleeved on the outside of each sliding rod.

[0007] As a further improvement to the above solution, the length of the connecting plate is greater than the distance between the two sets of top plates.

[0008] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the hot press table and the base plate, respectively.

[0009] As a further improvement to the above scheme, the bottoms of the two sets of pressure rollers are on the same horizontal plane.

[0010] As a further improvement to the above solution, the two ends of the second spring are fixedly connected to the connecting seat and the sliding plate, respectively.

[0011] As a further improvement to the above solution, the length of the pressure roller is smaller than the distance between the two sets of movable rods on the same side.

[0012] As a further improvement to the above solution, support legs are fixedly connected to the four corners of the bottom of the hot press table.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a hydraulic cylinder to push the hot press head at the bottom of the connecting plate vertically downwards, allowing the hot press head to approach the fabric and press the hot melt adhesive film onto the fabric. When the connecting plate contacts the two sets of top plates simultaneously, as the connecting plate continues to descend, it pushes the two sets of top plates downwards together. Utilizing the sliding engagement between the movable rod and the hot press table, the top plates drive the pressure rollers downwards as they descend. When the pressure rollers contact the surface of the fabric, as the hot press head continues to move downwards, and with the hinge engagement between connecting rod one and the top plate, the rotational connection between the pressure roller and connecting rod one, the sliding engagement between the slide plate and the slide bar, and the hinge engagement between the slide plate and connecting rod one and connecting rod two, the two sets of pressure rollers move to both sides simultaneously until the hot press head is in complete contact with the hot melt adhesive film. At this point, the two sets of pressure rollers can straighten and flatten the fabric and the hot melt adhesive film, thereby improving the pressing effect of the hot melt adhesive film.

[0014] 2. This utility model is not affected by the thickness of the fabric when processing it, and can straighten and flatten fabrics of different thicknesses, which improves the applicability of the device. Furthermore, the straightening and flattening of the fabric can be completed automatically and synchronously during the pressing process, thereby improving the pressing efficiency of the hot melt adhesive film and making it highly practical.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] Example 1: Please combine Figure 1-3 The hot melt adhesive film pressing device of this embodiment includes a hot press table 1, a bracket 2 fixedly connected to the hot press table 1, a hydraulic cylinder 3 fixedly connected to the bracket 2, a connecting plate 4 fixedly connected to the telescopic end of the hydraulic cylinder 3, and a hot press head 5 fixedly connected to the bottom of the connecting plate 4.

[0019] A leveling assembly for automatically straightening and leveling fabrics includes four sets of movable rods 101 symmetrically slidably connected to a hot press table 1. The top ends of two sets of movable rods 101 on the same side are fixedly connected to the same top plate 102, and the bottom ends of the two sets of movable rods 101 on the same side are fixedly connected to the same bottom plate 103. Springs 104 are sleeved on the outside of each movable rod 101, and both ends of the springs 104 are fixedly connected to the hot press table 1 and the bottom plate 103, respectively. Two sets of connecting rods 105 are symmetrically hinged to the bottom of the top plate 102. Pressure rollers 106 are rotatably connected between the ends of the two sets of connecting rods 105 on the same side. The bottoms of the two sets of pressure rollers 106 are at the same... On the horizontal plane, two sets of strip plates 107 are symmetrically fixedly connected to one side of the top plate 102. The bottom of the strip plate 107 is fixedly connected to the slide rod 108 through the connecting seat. The two sets of slide rods 108 on the same side are slidably connected to the same slide plate 109. The slide plate 109 and the connecting rod 105 are hinged to the connecting rod 2 110 through the hinge. The slide rod 108 is fitted with a spring 2 111. The two ends of the spring 2 111 are fixedly connected to the connecting seat and the slide plate 109 respectively. The length of the connecting plate 4 is greater than the distance between the two sets of top plates 102. The length of the pressure roller 106 is less than the distance between the two sets of movable rods 101 on the same side.

[0020] The implementation principle of the hot melt adhesive film pressing device in this embodiment is as follows: First, the hot melt adhesive film and the fabric are stacked together and placed on the hot press table 1. Then, the hydraulic cylinder 3 is activated, which pushes the hot press head 5 at the bottom of the connecting plate 4 to descend vertically, so that the hot press head 5 can move closer to the fabric to press the hot melt adhesive film and the fabric together. When the connecting plate 4 contacts the two sets of top plates 102 at the same time, as the connecting plate 4 continues to descend, it can push the two sets of top plates 102 to descend together. Utilizing the sliding cooperation between the movable rod 101 and the hot press table 1, the top plate 102 will drive the pressure roller 106 to descend when it descends. At this time, the spring 104 will be stretched. When the pressure roller 106 contacts the hot melt adhesive film on the surface of the fabric, as the hot press head 5 continues to move downward, and the connecting rod 105 and the top plate 102 are in contact with the fabric, the hot press head 5 will move closer to the fabric to press the hot melt adhesive film. The hinged connection between the two rollers 106 and the first connecting rod 105, the sliding connection between the slide plate 109 and the slide rod 108, and the hinged connection between the slide plate 109, the first connecting rod 105, and the second connecting rod 110 allow the two rollers 106 to move simultaneously to both sides until the hot press head 5 is in complete contact with the hot melt adhesive film. At this time, the two rollers 106 can automatically straighten and flatten the fabric and the hot melt adhesive film, thereby improving the pressing efficiency of the hot melt adhesive film. At this time, the second spring 111 will be compressed. When the pressing is completed, the hydraulic cylinder 3 drives the hot press head 5 to rise vertically. The spring 104 and the second spring 111 themselves will automatically reset the rollers 106. Finally, the fabric can be removed. The device is suitable for fabrics of different thicknesses and is highly practical.

[0021] Example 2: Based on Embodiment 1, this embodiment is further improved in that: support legs are fixedly connected to the four corners of the bottom of the hot press table 1, which can support the device.
