Description

Technical Field

[0001] This utility model relates to the technical field of membrane material feeding devices, and in particular to a membrane material feeding device. Background Technology

[0002] Melamine board, also known as melamine-impregnated paper-faced engineered wood, is a decorative board made by soaking paper with different colors or textures in melamine resin adhesive, drying it to a certain degree of curing, and then laying it on the surface of particleboard, moisture-resistant board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and then hot-pressing it.

[0003] A film is laid on the surface of the melamine board. During the film laying process, the rolled film needs to be released first and then laid on the surface of the melamine board. This type of structure can be referenced by a CNC large board hot glue wrapping machine disclosed in Chinese Patent Publication No. CN217993516U. It adopts a double unwinding mechanism with double air expansion shafts for air unwinding. The air expansion shafts are inserted into the paper tubes of the cut PVC film, and then air is inflated to fix the PVC film to the air expansion shafts and thus fix it on the equipment. The air expansion shafts are controlled by a magnetic powder brake.

[0004] Existing membrane material feeding devices typically employ a clamp-type locking structure to prevent the air shaft from rotating. The rotating end of the air shaft is fixed by the clamp and screws. However, the clamp-type structure makes disassembly and assembly difficult and inefficient when replacing the membrane material.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Detailed Implementation

[0025] This utility model provides a membrane material feeding device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Please refer to Figures 1 to 4 This embodiment discloses a membrane material feeding device, including a frame 21;

[0028] The feeding assembly 22 includes an air shaft 221 rotatably mounted on the frame 21 and used to feed out the film material 62, a magnetic powder brake 222 fixed to the frame 21 and detachably connected to one end of the air shaft 221, and the other end of the air shaft 221 is mounted on the frame 21.

[0029] The locking assembly 23 includes a stop 231 fixed to the frame 21, a pressure block 232 hinged to the frame 21 at one end, and a pneumatic device 233 hinged to the frame 21. The output shaft of the pneumatic device 233 is hinged to the pressure block 232. The pneumatic device 233 can push the swing end of the pressure block 232, so that the pressure block 232 clamps one end of the air shaft 221 in the locking groove formed by the cooperation of the pressure block 232 and the stop 231.

[0030] The hoisting mechanism 24 includes a hoisting beam 241 fixed to the top of the frame 21, a crane (not shown in the figure) fixed to the hoisting beam 241, a hoisting rope (not shown in the figure) driven by the crane to be released or wound, a hoisting plate 242 connected to the lower end of the hoisting rope, and a hook 243 provided at both ends of the hoisting plate 242 for hooking the end of the air shaft 221.

[0031] The film feeding device in this embodiment adds a locking component 23. The pressure block 232 is driven by a pneumatic device 233, enabling it to rotate around its axis. When the air shaft 221 needs to be fixed, the pneumatic device 233 pushes the swing end of the pressure block 232, causing the pressure block 232 to clamp one end of the air shaft 221 into the locking groove formed by the pressure block 232 and the stop block 231, preventing the air shaft 221 from shifting. If the air shaft 221 needs to be removed and replaced, it can be replaced with a new one. When the membrane material 62 is in place, the pressure block 232 is pulled by the pneumatic device 233, and the pressure block 232 no longer presses the end of the air shaft 221. The pneumatic clamping by the pneumatic device 233 has a simple structure and is easy to use, which improves the assembly and disassembly efficiency of the air shaft 221. Moreover, the piston of the pneumatic device 233 moves at a relatively fast speed, and it can perform clamping work without the aid of human power. Just press a button, and it can automatically center and clamp the air shaft 221 instantly, and the clamping force is stable and adjustable.

[0032] In addition, this application adds a hoisting mechanism 24, which uses a crane, hoisting plate 242, and hook 243 to hoist and replace the air shaft 221, reducing the difficulty of replacement.

[0033] It should be noted that the surface of the air shaft 221 can protrude after being inflated under high pressure, and the surface quickly retracts after deflating. As long as an air source is available, when it is necessary to lock the rolled film material 62, simply inflate it with an air gun to hold the rolled film material 62 in place. When it is necessary to loosen and unload the material, simply press the switch of the air nozzle by hand to remove it. The operation is simple. The magnetic powder brake 222 can be used with a fully automatic tension controller. It is only necessary to set the required tension for winding and unwinding. The fully automatic tension sensor can detect the tension of winding and unwinding in real time and transmit the detected tension data to the fully automatic tension controller in real time. The current input to the magnetic powder brake 222 is changed in real time according to the tension data to achieve a constant tension.

[0034] like Figure 2As shown, a bearing 223 is sleeved at the end of the air shaft 221, and the bearing 223 is mounted on the frame 21. The pneumatic device 233 can push the swing end of the pressure block 232, so that the pressure block 232 clamps the bearing 223 in the locking groove formed by the cooperation of the pressure block 232 and the stop block 231, thereby locking the air shaft 221. By pushing the pressure block 232 to rotate around its axis, the air shaft 221 can be locked or opened. When locked, the bearing 223 can be clamped in the locking groove formed by the cooperation of the pressure block 232 and the stop block 231. When opened, the air shaft 221 can be disassembled, which is convenient for the air shaft 221 to be reloaded into the roll of film 62.

[0035] Furthermore, the pressing block 232 has an L-shaped structure.

[0036] In addition, to prevent the pressure block 232 from causing wear on the bearing 223 and to increase the friction between the pressure block 232 and the bearing 223, an elastic rubber pad 230 can be added to the pressure block 232.

[0037] Please refer to Figure 4 In this embodiment, the tension adjustment assembly 25 includes a first conveying roller 251, a second conveying roller 252, and a third conveying roller 253 rotatably mounted on the frame 21. The first conveying roller 251, the second conveying roller 252, and the third conveying roller 253 are arranged in a triangular pattern. The film material 62 passes around the first conveying roller 251, the second conveying roller 252, and the third conveying roller 253 in sequence. The frame 21 is provided with a first waist hole 211 extending in the x-direction. The end of the third conveying roller 253 can be adjusted along the first waist hole 211 to adjust its position in the x-direction. By adjusting the position of the third conveying roller 253 in the x-direction, the tension of the film material 62 can be adjusted, making the film material 62 more tightly stretched, avoiding wrinkles in the film material 62, and ensuring the subsequent coating quality of the film material 62.

[0038] Furthermore, the lifting adjustment mechanism 26 includes a lifting drive device 261 fixed to the frame 21 and a limiting plate 262 connected to the output end of the lifting drive device 261; the limiting plate 262 limits the height of the film material 62 to ensure the subsequent coating quality.

[0039] Furthermore, the film material feeding device also includes a fourth conveying roller 27 rotatably mounted on the frame 21. The fourth conveying roller 27 is located directly below the third conveying roller 253. The frame 21 is provided with a second waist hole 212 extending in the x direction. The end of the fourth conveying roller 27 can be adjusted along the x direction along the second waist hole 212. The discharge flatness of the film material 62 is controlled by setting the fourth conveying roller 27, which is a clever structure.
