Description

A fast-feeding electroplated aluminum foil rewinding machine Technical Field

[0001] This utility model relates to the field of electroplated aluminum production technology, specifically to an electroplated aluminum hot stamping foil rewinding machine that can quickly unload materials. Background Technology

[0002] Hot stamping is a decorative printing process that uses heat and pressure to transfer the metallic coating or pigment on an electroplated aluminum foil to the surface of a substrate. Specifically, under certain temperature and pressure, the electroplated aluminum foil comes into close contact with the substrate, and the hot-melt adhesive layer on the electroplated aluminum foil melts, transferring the aluminum layer and other materials onto the substrate, thereby forming patterns, text, or decorative areas with metallic luster or other special effects on the surface of the substrate.

[0003] A search revealed that patent application number 202322192662.0 discloses a hot stamping device for electroplated aluminum, comprising a worktable, a mounting plate on the worktable, and an electroplated aluminum winding mechanism, a hot stamping mechanism, and a pushing mechanism on the mounting plate; the electroplated aluminum winding mechanism includes an electroplated aluminum unwinding roller, multiple conveying rollers, and an electroplated aluminum rewinding roller; the hot stamping mechanism includes a telescopic hot stamping head one mounted on the mounting plate and a telescopic hot stamping head two mounted on the worktable; the pushing mechanism includes a telescopic push rod;

[0004] Although the hot stamping device for electroplated aluminum foil uses hot stamping mechanisms on both sides of the electroplated aluminum foil winding mechanism to perform double-sided hot stamping and achieves automatic winding of the electroplated aluminum foil through the electroplated aluminum foil winding mechanism, this hot stamping device is not convenient for cleaning the surface of the electroplated aluminum foil before hot stamping. The electroplated aluminum foil is thin and light and is very prone to static electricity. During storage, transportation and installation, the surface is very easy to attract dust and other tiny particles. If the dust adhering to the surface of the electroplated aluminum foil is not effectively removed, it will not only affect the normal adhesion of the hot melt adhesive layer between the electroplated aluminum foil and the substrate during the hot stamping process, but may also cause defects such as spots, blurring, and partial missing parts of the hot stamping pattern, which will seriously reduce the hot stamping quality and product aesthetics.

[0005] Therefore, we propose a fast-feeding electroplated aluminum foil rewinding machine. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an electroplated aluminum foil rewinding machine that can quickly unload materials, solving the problem that existing devices are not convenient for cleaning dust from the surface of electroplated aluminum foil, which easily leads to poor hot stamping results.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an electroplated aluminum hot stamping foil rewinding machine with rapid material feeding, comprising a U-shaped plate, a conveyor belt assembly inside the U-shaped plate, a lower telescopic hot stamping head fixedly installed on the rear side wall inside the U-shaped plate, an upper telescopic hot stamping head arranged directly above the lower telescopic hot stamping head, a vertical plate fixedly installed on the rear side of the top surface of the U-shaped plate, an unwinding assembly arranged on the vertical plate, the unwinding assembly comprising an unwinding roller, a take-up roller and four conveying rollers, the unwinding roller and the take-up roller being symmetrically arranged on the left and right sides of the upper telescopic hot stamping head and rotatably mounted on the side wall of the vertical plate through bearing rings, and the four conveying rollers being arranged in pairs and symmetrically distributed on the left and right sides of the lower telescopic hot stamping head;

[0008] A cleaning component is provided on the left side of the lower telescopic hot stamping head and the upper telescopic hot stamping head, and a feeding component is provided inside the U-shaped plate;

[0009] The cleaning assembly includes a U-shaped suction plate, suction holes, an industrial vacuum cleaner, and a suction tube. The U-shaped suction plate is inclined and fixedly installed on the side wall of the vertical plate. The U-shaped suction plate is located in the middle of the unwinding assembly and the lower telescopic hot stamping head. The U-shaped suction plate is hollow inside and its inner wall has evenly distributed suction holes. The industrial vacuum cleaner is fixedly installed on the front side wall of the U-shaped plate. The suction end of the industrial vacuum cleaner is fixedly connected to the suction tube. The end of the suction tube away from the industrial vacuum cleaner is fixedly installed on the side wall of the suction hole and communicates with its inner cavity.

[0010] Preferably, the feeding assembly includes a support plate, a hydraulic rod, a brush plate, brush bristles, and a guide plate. The support plate is fixedly installed on the rear side of the inner wall of the U-shaped plate. The support plate is located on the left side of the lower telescopic hot stamping head. A hydraulic rod is fixedly installed on the side wall of the support plate. A brush plate is fixedly installed at the output end of the hydraulic rod. The brush plate can be pushed to move laterally by the hydraulic rod.

[0011] Preferably, the bottom surface of the brush plate is fixedly equipped with evenly distributed bristles, and the bottom surface of the bristles is flush with the top surface of the lower telescopic hot stamping head after it has retracted and reset. When the brush plate moves, it moves the bristles together, and then pushes the hot stamped product located on the top surface of the lower telescopic hot stamping head down through the bristles.

[0012] Preferably, the brush bristles are made of PBT material, and a downwardly inclined guide plate is fixedly installed on the right side of the lower telescopic hot stamping head. The top of the guide plate is flush with the top surface of the lower telescopic hot stamping head after it has retracted and reset. The guide plate guides the hot stamping product that has been pushed down, so that the hot stamping product slides down the top surface of the guide plate onto the conveyor belt assembly.

[0013] Preferably, the unwinding assembly further includes a first pulley, a second pulley, a transmission belt, a motor, and a U-shaped mounting plate. The ends of the unwinding roller and the winding roller near the vertical plate both penetrate the side wall of the vertical plate and are respectively fixedly mounted with the first pulley and the second pulley. The transmission belt is sleeved on the first pulley and the second pulley. The transmission belt connects the second pulley and the first pulley, enabling the first pulley and the second pulley to rotate synchronously.

[0014] Preferably, a U-shaped mounting plate is fixedly installed on the back of the vertical plate, and a motor is fixedly installed on the inner wall of the U-shaped mounting plate. The second pulley is fixedly installed on the output end of the motor. The motor drives the second pulley to rotate, and then the second pulley drives the transmission belt and the first pulley to rotate together, so that the unwinding roller and the winding roller can rotate, thereby completing the unwinding and winding work simultaneously.

[0015] This utility model provides an electroplated aluminum hot stamping foil rewinding machine with rapid material feeding. It has the following beneficial effects:

[0016] 1. This fast-feeding electroplated aluminum foil rewinding machine allows the electroplated aluminum foil to pass through a U-shaped dust collection plate before hot stamping. An industrial vacuum cleaner then collects the dust adhering to the surface of the foil, allowing it to enter the U-shaped dust collection plate through suction holes and finally into the industrial vacuum cleaner through a suction pipe. This facilitates dust removal, preventing dust from affecting the hot stamping effect and improving the overall result. It solves the problem of existing devices being inconvenient to clean dust from the surface of the electroplated aluminum foil, which can easily lead to poor hot stamping results.

[0017] 2. This fast-feeding electroplated aluminum foil rewinding machine uses a hydraulic rod to move the brush plate and bristles towards the side closer to the lower telescopic hot stamping head. This pushes down the hot stamping product located on the top surface of the lower telescopic hot stamping head, and then the hot stamping product slides down along the guide plate onto the conveyor belt assembly. The conveyor belt assembly transports the hot stamping product, achieving the purpose of fast feeding. The bristles can also prevent scratching the surface of the hot stamping product and clean the dust on the top surface of the lower telescopic hot stamping head, further improving the hot stamping effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As shown in Figures 1-4: Includes a U-shaped plate 1, with a conveyor belt assembly 2 inside. A lower telescopic hot stamping head 3 is fixedly installed on the rear side wall inside the U-shaped plate 1. An upper telescopic hot stamping head 4 is positioned directly above the lower telescopic hot stamping head 3. A vertical plate 5 is fixedly installed on the rear side of the top surface of the U-shaped plate 1. An unwinding assembly 7 is installed on the vertical plate 5, including an unwinding roller 71, a take-up roller 72, and four conveyor rollers 73. The unwinding roller 71 and take-up roller 72 are symmetrically arranged on the left and right sides of the upper telescopic hot stamping head 4 and are rotatably mounted on the side wall of the vertical plate 5 via bearing rings. The four conveyor rollers 73 are arranged in pairs and symmetrically distributed on the left and right sides of the lower telescopic hot stamping head 3. A cleaning assembly 6 is located on the left side of the lower telescopic hot stamping head 3 and the upper telescopic hot stamping head 4. A material feeding assembly 8 is installed inside the U-shaped plate 1. The cleaning assembly 6 includes a U-shaped dust suction plate 61, a dust suction hole 62, an industrial vacuum cleaner 63, and a dust suction pipe 64. The U-shaped dust-collecting plate 61 is inclined and fixedly installed on the side wall of the vertical plate 5. The U-shaped dust-collecting plate 61 is located in the middle of the unwinding assembly 7 and the lower telescopic hot stamping head 3. The U-shaped dust-collecting plate 61 is hollow inside and its inner wall has evenly distributed dust-collecting holes 62. The industrial vacuum cleaner 63 is fixedly installed on the front side wall of the U-shaped plate 61. The dust-collecting end of the industrial vacuum cleaner 63 is fixedly connected to the dust-collecting pipe 64. The end of the dust-collecting pipe 64 away from the industrial vacuum cleaner 63 is fixedly installed on the side wall of the dust-collecting hole 62 and connected to its inner cavity. By allowing the electroplated aluminum foil before hot stamping to pass through the U-shaped dust-collecting plate 61 and the industrial vacuum cleaner 63 to perform dust collection, the dust attached to the surface of the electroplated aluminum foil can enter the interior of the U-shaped dust-collecting plate 61 through the dust-collecting hole 62 and finally enter the interior of the industrial vacuum cleaner 63 through 64. This achieves the purpose of facilitating dust cleaning, avoiding the influence of dust on the hot stamping effect, and improving the hot stamping effect.

[0025] Example 2: As shown in Figures 1 and 4: The feeding assembly 8 includes a support plate 81, a hydraulic rod 82, a brush plate 83, brush bristles 84, and a guide plate 85. The support plate 81 is fixedly installed on the rear side of the inner wall of the U-shaped plate 1. The support plate 81 is located on the left side of the lower telescopic hot stamping head 3. The hydraulic rod 82 is fixedly installed on the side wall of the support plate 81. The brush plate 83 is fixedly installed at the output end of the hydraulic rod 82. The bottom surface of the brush plate 83 is fixedly installed with evenly distributed brush bristles 84. The bottom surface of the brush bristles 84 is flush with the top surface of the lower telescopic hot stamping head 3 after it has retracted and reset. The brush bristles 84 are made of PBT material. The right side of the lower telescopic hot stamping head 3 is fixedly installed with a downwardly inclined guide plate 85. The guide plate 85 is set so that its top end is flush with the top surface of the lower telescopic hot stamping head 3 after it has retracted and reset. The hydraulic rod 82 drives the brush plate 83 and brush bristles 84 to move towards the side closer to the lower telescopic hot stamping head 3, which can push the hot stamping finished product located on the top surface of the lower telescopic hot stamping head 3 down. Then the hot stamping finished product slides down along the guide plate 85 onto the conveyor belt assembly 2. The conveyor belt assembly 2 transports the hot stamping finished product, achieving the purpose of rapid unloading. The brush bristles 84 can prevent scratching the surface of the hot stamping finished product. At the same time, the brush bristles 84 can clean the dust on the top surface of the lower telescopic hot stamping head 3, further improving the hot stamping effect.

[0026] Example 3: As shown in Figures 1-3: The unwinding assembly 7 also includes a first pulley 74, a second pulley 75, a transmission belt 76, a motor 77, and a U-shaped mounting plate 78. The unwinding roller 71 and the take-up roller 72, near the end of the vertical plate 5, both penetrate the side wall of the vertical plate 5 and are respectively fixedly mounted with the first pulley 74 and the second pulley 75. The transmission belt 76 is sleeved on the first pulley 74 and the second pulley 75. The U-shaped mounting plate 78 is fixedly mounted on the back of the vertical plate 5. The motor 77 is fixedly mounted on the inner wall of the U-shaped mounting plate 78. The second pulley 75 is fixedly mounted on the output end of the motor 77. The second pulley 75 drives the transmission belt 76 and the motor 77 to rotate, causing the take-up roller 72 and the unwinding roller 71 to rotate together, simultaneously winding and unwinding the electroplated aluminum foil, thereby adjusting the hot stamping position of the electroplated aluminum foil.

[0027] The working principle and usage process of this utility model: When using this electroplated aluminum foil rewinding machine that can quickly unload materials, the electroplated aluminum foil is placed on the outer surface of the unwinding roller 71, and the free end of the electroplated aluminum foil passes through the U-shaped dust suction plate 61, then passes through the two types of conveying rollers 73 in sequence, and finally is wound around the outer surface of the rewinding roller 72. Then, the lower telescopic hot stamping head 3 and the upper telescopic hot stamping head 4 are started to perform hot stamping on the upper and lower sides of the electroplated aluminum foil. After hot stamping, the electroplated aluminum foil is separated from the surrounding electroplated aluminum foil under the action of high temperature. At the same time, the motor 77 is started to drive the second pulley 75 to rotate. Then, the second pulley 75 drives the transmission belt 76 and the motor 77 to rotate, so that the rewinding roller 72 and the unwinding roller 71 rotate together, and the electroplated aluminum foil is wound and unwound at the same time. Then, the hot stamping position of the electroplated aluminum foil is adjusted.

[0028] Before hot stamping, when the electroplated aluminum foil passes through the U-shaped dust collection plate 61, the industrial vacuum cleaner 63 is activated to perform dust collection. Then, the dust on the surface of the electroplated aluminum foil enters the interior of the U-shaped dust collection plate 61 through the dust collection hole 62, and finally enters the interior of the industrial vacuum cleaner 63 through the dust collection pipe 64.

[0029] The hydraulic rod 82 is activated to move the brush plate 83 and brush bristles 84 to the side closer to the lower telescopic hot stamping head 3, which can push the hot stamping finished product located on the top surface of the lower telescopic hot stamping head 3 down. Then the hot stamping finished product slides down along the guide plate 85 onto the conveyor belt assembly 2, and is transported by the conveyor belt assembly 2.
