Description

Technical Field

[0001] This utility model relates to the field of printing and hot stamping equipment technology, and more specifically, to an electroplated aluminum coil winding and unwinding device. Background Technology

[0002] Electroplated aluminum foil is a hot stamping material made by coating and vacuum evaporation of a metal foil layer onto a thin film substrate. The thickness of electroplated aluminum foil is generally 12, 16, 18, or 20 μm. Electroplated aluminum foil is made by coating a release layer and a color layer onto a thin film, vacuum metallizing it, coating an adhesive layer, and finally rewinding the finished product. Generally, a 16 μm thick biaxially oriented polyester film is used as the base film layer. Its main function is to support the coating layer attached to it and facilitate continuous operation during hot stamping. The base film layer should not deform due to temperature rise during the hot stamping process and should have high strength, tensile strength, and high temperature resistance. Therefore, a winding and unwinding device is required in the production process of electroplated aluminum foil.

[0003] Traditional electroplated aluminum winding and unwinding devices typically use a single conveyor roller. During the winding process, due to the lack of a tensioning device, deviation or wrinkles are prone to occur, affecting product quality. Based on the above problems, we propose an electroplated aluminum winding and unwinding device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an electroplated aluminum winding and unwinding device to solve the problem that traditional electroplated aluminum winding and unwinding devices are prone to deviation or wrinkles during use, which in turn affects product quality.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an electroplated aluminum winding and unwinding device, including a winding assembly and a tensioning and smoothing assembly; the winding assembly includes a base, a support wall disposed on one side of the top of the base, a motor disposed on one side of the support wall, and a winding roller disposed at the output end of the motor; the tensioning and smoothing assembly includes a fixed plate disposed on one side of the support wall, a fixed sleeve disposed in the middle of the fixed plate, a torsion spring disposed inside the fixed sleeve, a rotating shaft disposed inside the fixed sleeve and connected to the torsion spring, a turntable disposed at one end of the rotating shaft, a curved arm disposed on the surface of the turntable, a connecting rod disposed at one end of the curved arm, a tensioning roller disposed on the connecting rod on the side away from the tensioning roller, a mounting bracket disposed on the connecting rod on the side close to the tensioning roller, a smoothing roller disposed between the mounting brackets, and a rubber scraper disposed on one side of the smoothing roller; During the winding process of the take-up roller winding the electroplated aluminum, the electroplated aluminum passes through the bottom of the tension roller and wraps around the surface of the take-up roller. The smoothing roller, under the action of the torsion spring, attaches to the surface of the take-up roller and presses and flattens the electroplated aluminum wrapped on the surface of the take-up roller. As the thickness of the electroplated aluminum increases, the smoothing roller moves upward, causing the curved arm to rotate counterclockwise, which in turn causes the tension roller to move downward, continuously tensioning the electroplated aluminum.

[0006] Preferably, it also includes a recycling component, which includes a collection box disposed on the top of the base, a suction port disposed on the top of the collection box, and a negative pressure pump disposed on one side of the support wall. The negative pressure pump is connected to the collection box through a detachable connecting pipe. The inside of the suction port is provided with a mesh grille. The collection box is detachably connected to the base.

[0007] Preferably, a groove is provided on one side of the top of the base, a slide block is provided on the top of the groove that slides left and right along the groove, a bracket is provided on the top of the slide block, and a connecting sleeve adapted to the take-up roller is provided on one side of the bracket.

[0008] Preferably, a threaded pin is provided on one side of the slide block, and a pin hole that mates with the threaded pin is provided on one side of the slide groove.

[0009] Preferably, the surface of the smoothing roller is provided with a silicone layer, the surface of the silicone layer is provided with gradient micro-protrusions, the cross-section of the gradient micro-protrusions is arranged in an isosceles trapezoid, the direction of the ridges is parallel to the axis of the smoothing roller, and the surface of the tensioning roller is covered with a TPV adhesive layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a tensioning and smoothing component, utilizing the elasticity of a torsion spring to keep the smoothing roller always in contact with the surface of the take-up roller, pressing and smoothing the electroplated aluminum wrapped on the surface of the take-up roller. As the take-up diameter increases, the smoothing roller can automatically adjust its position to maintain the pressing and smoothing effect, while simultaneously driving the tensioning roller to move downwards to maintain tension on the electroplated aluminum, effectively preventing wrinkles. By setting a silicone layer on the surface of the smoothing roller, the smoothing roller can softly fit the take-up roller, evenly transmitting smoothing pressure and avoiding material indentations. The surface of the silicone layer is provided with gradient micro-convex ridges, which can "actively guide" the material to diffuse towards the center, solving the problem of edge wrinkle accumulation during take-up.

[0011] 2. This utility model also incorporates a winding assembly, a tensioning and smoothing assembly, and a recycling assembly. The bracket and connecting sleeve in the winding assembly can effectively support one end of the winding roller, preventing the winding roller from being subjected to force on one side and avoiding bending and deformation. The rubber scraper in the tensioning and smoothing assembly can scrape off aluminum shavings adhering to the surface of the electroplated aluminum during the winding process. The recycling assembly can effectively collect aluminum shavings generated during the winding process. The negative pressure generated by the negative pressure pump draws the aluminum shavings into the collection box through the dust suction port, facilitating the recycling of the aluminum shavings.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: This utility model relates to an electroplated aluminum winding and unwinding device, including a winding assembly 1 and a tensioning and smoothing assembly 2. The winding assembly 1 includes a base 101, a support wall 102 fixedly connected to one side of the top of the base 101, a motor 103 fixedly connected to one side of the support wall 102, and a winding roller 104 fixedly connected to the output end of the motor 103. The base 101 provides a stable mounting platform for all components, ensuring the overall stability of the equipment during the winding process and avoiding winding deviation caused by vibration. The support wall 102 is used to install components such as the motor 103 and the fixing plate 201. The motor 103, as the core component providing winding power, drives the winding roller 104 to rotate through its output end. The winding roller 104 serves as the direct... The components for winding electroplated aluminum; the tensioning and smoothing assembly 2 includes a fixed plate 201 fixedly connected to one side of the support wall 102, a fixed sleeve 202 fixedly connected to the middle of the fixed plate 201, a torsion spring 203 fixedly connected inside the fixed sleeve 202, a rotating shaft 204 rotatably connected inside the fixed sleeve 202 and connected to the torsion spring 203, a turntable 205 fixedly connected to one end of the rotating shaft 204, a crank arm 206 fixedly connected to the surface of the turntable 205, a connecting rod 207 fixedly connected to one end of the crank arm 206, a tensioning roller 208 rotatably connected to the connecting rod 207 on the side away from the tensioning roller 208, and a mounting bracket 209 fixedly connected to the connecting rod 207 on the side near the tensioning roller 208. A smoothing roller 2010 is dynamically connected to the mounting bracket 209, and a rubber scraper 2011 is fixedly connected to one side of the smoothing roller 2010. A fixing plate 201 is used to fix the tensioning and smoothing assembly 2 as a whole to the support wall 102, providing an installation reference. A fixing sleeve 202 serves as the mounting carrier for the rotating shaft 204 and the torsion spring 203. The rigid structure ensures the stable transmission of the elastic force of the torsion spring 203. The torsion spring 203, as the core power source for automatic adjustment, maintains the rotation tendency of the rotating shaft 204 through preload, providing continuous pressure for the smoothing roller 2010 to adhere to the take-up roller 104. The rotating shaft 204, as the torque transmission hub, transmits the force of the torsion spring 203 to the crank arm 206, realizing tensioning and smoothing. The linkage adjustment is achieved by turning 205 to drive the crank arm 206 to rotate. The crank arm 206 uses the lever principle to convert the rotational motion of the rotating shaft 204 into the positional changes of the tension roller 208 and the smoothing roller 2010, thus realizing the linkage action of the two. The connecting rod 207 is used to install the tension roller 208 and the mounting frame 209. The tension roller 208 pre-tensions the electroplated aluminum through its own weight and the pressure transmitted by the crank arm 206 to prevent the material from loosening. The mounting frame 209 is used to install the smoothing roller 2010 and the rubber scraper 2011. The smoothing roller 2010 is used to eliminate wrinkles. The rubber scraper 2011 removes small impurities and aluminum chips from the surface of the electroplated aluminum before winding, preventing impurities from being rolled in and forming indentations or damaging the material.This invention utilizes a tensioning and smoothing assembly 2, where the torsion spring 203 keeps the smoothing roller 2010 in constant contact with the surface of the take-up roller 104, thus pressing and smoothing the electroplated aluminum wound on the surface of the take-up roller 104. As the take-up diameter increases, the smoothing roller 2010 automatically adjusts its position to maintain the pressing and smoothing effect, while simultaneously driving the tensioning roller 208 downward to maintain tension on the electroplated aluminum, effectively preventing wrinkles.

[0015] Specifically, it also includes a recycling component 3, which includes a collection box 301 snapped onto the top of the base 101, a suction port 302 fixedly connected to the top of the collection box 301, and a negative pressure pump 303 fixedly connected to one side of the support wall 102. The negative pressure pump 303 is connected to the collection box 301 via a detachable connecting pipe. A mesh grille is installed inside the suction port 302. The collection box 301 is detachably connected to the base 101. The collection box 301 is used to store aluminum shavings generated during the winding process and adopts a detachable design for easy regular cleaning. 02 Align the contact area between the take-up roller 104 and the smoothing roller 2010, and adsorb aluminum shavings through negative pressure. The internal mesh grid can filter large impurities. The negative pressure pump 303 provides adsorption power. A negative pressure environment is formed in the collection box 301 through the connecting pipe, and the aluminum shavings are sucked into the collection box 301 from the dust suction port 302. The pipe adopts a detachable design for easy cleaning and maintenance. The setting of the recycling component 3 can effectively collect the aluminum shavings generated during the winding process. The negative pressure generated by the negative pressure pump 303 sucks the aluminum shavings into the collection box 301 through the dust suction port 302, which facilitates the recycling of aluminum shavings.

[0016] More specifically, a slide groove 105 is installed on one side of the top of the base 101. A slide block 106 that slides left and right along the slide groove 105 is slidably connected to the top of the slide groove 105. A bracket 107 is fixedly connected to the top of the slide block 106. A connecting sleeve 108 that is adapted to the take-up roller 104 is fixedly connected to one side of the bracket 107. The slide groove 105 and the slide block 106 are used to adjust the position of the connecting sleeve 108. The bracket 107 is used to support the connecting sleeve 108. The connecting sleeve 108 is used to fix the end of the take-up roller 104 away from the motor 103 to prevent the take-up roller from being subjected to force on one side and avoid bending and deformation.

[0017] It is worth mentioning that a threaded pin is screwed to one side of the slide block 106, and a pin hole that mates with the threaded pin is opened on one side of the slide groove 105. The threaded pin and the pin hole are used to fix the position of the slide block 106 on the slide groove 105 and improve the stability during the winding process.

[0018] It is worth noting that the smoothing roller 2010 has a silicone layer 2012 bonded to its surface, and the silicone layer 2012 has a gradient micro-protrusion ridge 2013 bonded to its surface. The cross-section of the gradient micro-protrusion ridge 2013 is set in an isosceles trapezoid, and the direction of the ridge is parallel to the axis of the smoothing roller 2010. The silicone layer 2012 on the surface of the smoothing roller 2010 has appropriate elasticity and can closely adhere to the surface of the take-up roller 104, smoothing the electroplated aluminum through the pressing action. The gradient micro-protrusion ridge 2013 on the surface of the silicone layer 2012 further enhances the smoothing effect, guides the material to spread evenly, and avoids local accumulation and wrinkling. The surface of the tension roller 208 is covered with a TPV adhesive layer. The TPV adhesive layer has elasticity and wear resistance, which ensures stable tension and avoids scratching the electroplated aluminum.

[0019] Working principle: This embodiment provides an electroplated aluminum winding and unwinding device. In use, the winding sleeve for winding the electroplated aluminum is inserted into the surface of the winding roller 104. Then, the sliding block 106 is slid to engage the connecting sleeve 108 with the other end of the winding roller 104, and a threaded pin is inserted to fix the position of the sliding block 106. One end of the electroplated aluminum is passed through the bottom of the tension roller 208 and wound around the winding sleeve on the surface of the winding roller 104. The motor 103 is started, and the winding roller 104 begins to rotate and wind the electroplated aluminum. Under the action of the torsion spring 203, the smoothing roller... The smoothing roller 2010 is always attached to the surface of the winding roller 104 to press and level the electroplated aluminum. As the winding thickness increases, the smoothing roller 2010 moves upward, causing the curved arm 206 to rotate counterclockwise around the rotating shaft 204, while simultaneously causing the tension roller 208 to move downward to maintain the tension on the electroplated aluminum. The negative pressure pump 303 is started, and the aluminum chips generated during the winding process enter the collection box 301 through the dust suction port 302 under the action of negative pressure. After winding is completed, the threaded pin is unscrewed, the slide block 106 is slid, and the wound electroplated aluminum coil can be removed.
