Description

Technical Field

[0001] This utility model relates to the field of adhesive film docking fixtures, specifically a hot melt adhesive film docking fixture. Background Technology

[0002] Adhesive film joining fixtures are used for continuous joining of adhesive films. Hot melt adhesive films are film products with or without release paper, allowing for convenient continuous or intermittent operation. They can be widely used for bonding various fabrics, papers, polymer materials, and metals.

[0003] For example, the authorized patent with publication number CN213137852U (Hot Melt Adhesive Film Butt Assembly Fixture) includes support plates, with fixing mechanisms installed above both support plates. Rollers are rotatably connected to vertical rods via pins. The upper outer wall of the vertical rod is clearance-fitted with the middle inner wall of the spring and the upper middle inner wall of the clamping plate. This hot melt adhesive film butt assembly fixture stretches and straightens the adhesive film on both sides, facilitating subsequent butt assembly and alignment. It solves the problem of misalignment at the joint caused by the inability to fix the hot melt adhesive film during butt assembly in existing hot melt adhesive film butt assembly fixtures. The slider can drive the fan to move back and forth, evenly blowing cold air onto the butt assembly area, rapidly cooling and drying it, facilitating re-butt assembly, saving time, and improving work efficiency. It also solves the problem of existing hot melt adhesive film butt assembly fixtures failing to rapidly cool the joint after butt assembly, thus affecting work efficiency.

[0004] The aforementioned existing hot melt adhesive film docking fixtures are not convenient enough for feeding hot melt adhesive films, and cannot perform continuous and uninterrupted feeding and docking, resulting in low docking efficiency. Furthermore, they cannot protect the adhesive film during the docking process, making the docking process unsafe and unstable. Utility Model Content

[0005] The purpose of this utility model is to provide a hot melt adhesive film docking fixture to solve the problems of the hot melt adhesive film docking fixture proposed in the background art being inconvenient for feeding hot melt adhesive film, unable to perform continuous and uninterrupted feeding and docking, resulting in low docking efficiency, and unable to protect the adhesive film during the docking process, making the docking process unsafe and unstable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot melt adhesive film butt welding fixture, comprising a top plate, a butt welding mold, a support, and a butt welding pressure head. The butt welding mold is provided between the top plate and the support. A hydraulic rod is provided on the cylinder mounting port at the top center of the top plate. A control panel is provided on one side of the top of the top plate. The ends of the top plate and the support are respectively provided with an upper feeding roller and a lower feeding roller through side guard plates. The bottom of the support is provided with a support leg.

[0007] In a further embodiment, the bottom of the support leg is provided with a support pad, and there are four support legs in total, with a reinforcing rod provided at the upper position between the four support legs.

[0008] In a further embodiment, the telescopic end of the hydraulic rod is provided with a docking pressure head, which is positioned opposite the pressure-resistant pad, which is located at the top center of the support.

[0009] In a further embodiment, the docking mold has a docking interface in the middle, which is directly opposite the docking points of the upper and lower feeding rollers.

[0010] In a further embodiment, the top of the support is provided with a plurality of conveying rollers, and the top end face of the conveying rollers is configured to correspond to the interface.

[0011] In a further embodiment, the bottom of the docking head is provided with an electric heating strip, the width of which is the same as that of the pressure-resistant pad, and the lower feeding roller and the film feeding roller are arranged opposite each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The mating mold of this utility model is provided with a top plate and a support on the upper and lower end faces respectively. An upper feeding roller and a lower feeding roller are provided at the ends of the top plate and the support respectively. The symmetrically arranged upper and lower feeding rollers facilitate the continuous feeding of the two sets of hot melt adhesive films to be mated, and can perform preliminary bonding, which is convenient for feeding and can ensure the accuracy of the interface after feeding.

[0014] 2. The docking mold of this utility model has a docking interface in the middle and multiple conveying rollers at the bottom of the docking mold, which facilitates stable conveying of the bonded adhesive film. The docking mold can also limit and protect the film, preventing external interference and ensuring the stability and safety of the conveying. Furthermore, the docking pressure head rises and falls from the middle of the docking mold, which can provide heat insulation protection for the hot melt adhesive film during the docking process, improving the safety of the docking.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a hot melt adhesive film butt welding fixture, including a top plate 3, a butt welding mold 4, a support 15, and a butt welding pressure head 16. The butt welding mold 4 is located between the top plate 3 and the support 15. A hydraulic rod 5 is provided on the cylinder mounting port 12 at the top center of the top plate 3. A control panel 6 is provided on one side of the top of the top plate 3. Upper feeding rollers 1 and lower feeding rollers 2 are respectively provided at the ends of the top plate 3 and the support 15 via side guard plates 11. Support legs 8 are provided at the bottom of the support 15. The butt welding mold 4 is used to complete the butt welding of the adhesive film within it, and the hydraulic rod... 5. The control head 16 performs docking processing on the laminated adhesive film. The upper feeding roller 1 and the lower feeding roller 2 are used to simultaneously transport multiple adhesive films, and can make double films bonded and the ends aligned. The support legs 8 are used to elevate and support the support base 15. The bottom of the support legs 8 is provided with support pads 10. There are four support legs 8 in total, and a reinforcing rod 9 is provided at the upper position between the four support legs 8. The support pads 10 can stably support the support legs 8, and the reinforcing rod 9 can strengthen the support of the four support legs 8.
