Description

Technical Field

[0001] This utility model relates to the field of hot stamping foil processing technology, and more specifically, to a dust-free hot stamping foil slitting device. Background Technology

[0002] Hot stamping foil is a commonly used material for decoration and anti-counterfeiting. It consists of a base layer, a release layer, a coloring layer, a metallized layer, and an adhesive layer. The base layer is usually a PET film to ensure stability during hot stamping. The coloring layer determines the foil's color, commonly including gold, silver, red, and blue, and custom colors are also available. The metallized layer imparts a metallic luster, enhancing the texture. The adhesive layer ensures adhesion to the substrate at high temperatures. Using a hot stamping machine under high temperature and pressure, the foil layer is transferred from the base layer to surfaces such as paper, leather, and plastic. It is widely used in packaging, book covers, gift boxes, and trademarks, enhancing the product's premium feel and brand recognition. High-quality hot stamping foil has strong adhesion, long-lasting shine, and some models possess anti-counterfeiting properties, making it an important material for increasing product added value.

[0003] In the production and processing of hot stamping foil, wide strips of foil need to be cut into several narrow strips. During the operation, due to the differences in physical properties of the various layers of the foil (especially the PET base film, the metallized layer, and the coloring layer), a large number of tiny particles are easily generated due to cutting stress. These particles include film fragments, aluminum shavings, and pigment powder, which not only accumulate dust inside the equipment but also diffuse into the production environment, posing a potential hazard to the respiratory system of operators. Therefore, we propose a dust-free hot stamping foil cutting device. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of the dust collection box and dust collection pipe structure, uses a dust collection box in the dust removal mechanism to generate negative pressure with the fan. The suction is transmitted to the dust collection box located on the outside of the blade through the negative pressure pipe. The ring-shaped structure can accurately absorb the dust generated during the cutting process. This dust enters the dust collection box through the negative pressure pipe and is then blocked from being discharged by the dust filter. This achieves efficient dust collection, avoids dust accumulation inside the equipment and diffusion into the production environment, protects the respiratory health of operators, and solves the problem of particulate dust generated during the cutting process of hot stamping foil.

[0013] 2. This utility model also improves the slitting quality by designing the structure of the blade and the grinding block. During the slitting process, the spring on the upper side of the dust collection box will exert a squeezing effect on the grinding block, so that the grinding block contacts the cutting edge of the blade. As the blade rotates, the grinding block can continuously grind the blade, preventing the blade from producing burrs due to wear, thereby ensuring the flatness of the hot stamping foil slitting cut, reducing slitting quality defects caused by blade problems, eliminating the need for frequent blade replacement, and reducing the complexity and cost of operation.

[0014] 3. This utility model, through the design of a dust collection box and a limiting rod structure, has a first ball bearing at the bottom of the dust collection box that contacts the blade and limits its rotation without affecting it. The limiting rod is bent three times so that its end position is located on the side of the take-up drum on both sides. Together with the second ball bearing contacting the side of the take-up drum, it can limit the take-up drum, effectively preventing relative movement between the blade and the take-up drum during operation, ensuring the accuracy of the cutting and winding positions, and improving the stability and reliability of the overall processing. Secondly, the dust collection box is easy to disassemble, and with the movable and adjustable setting of the third mounting plate, it is easy to disassemble and assemble the take-up drum and the blade.

[0024] like Figures 1 to 8 As shown, this utility model relates to a dust-free hot stamping foil slitting device, which includes a slitting mechanism 100 and a dust removal mechanism 200 provided on the slitting mechanism 100. The slitting mechanism 100 includes a base plate 101 and a first mounting plate 102 and a second mounting plate 103 symmetrically arranged on the base plate 101. At least two tension rollers 108 are rotatably mounted between the first mounting plate 102 and the second mounting plate 103. A take-up shaft 109 and a cutter shaft 111 are rotatably mounted on the side end of the first mounting plate 102. A take-up drum 1091 is movably arranged on the take-up shaft 109, and a blade 112 is movably arranged on the cutter shaft 111. The dust removal mechanism 200 includes a dust collection box 201 provided on the upper end of the first mounting plate 102 and the second mounting plate 103 and a dust suction box 203 provided on the outside of the blade 112. This utility model uses a dust collection box 203 and a dust collection box 201 to accurately absorb the dust generated during cutting, preventing it from spreading and harming health; the grinding block 206 continuously grinds the blade 112 to ensure a smooth cut and reduce the frequency of replacement; the limiting structure ensures that the blade 112 and the winding drum 1091 work stably and are easy to disassemble and assemble, thus improving processing efficiency and quality.

[0025] Specifically, a hydraulic device 104 is provided on the outer surface of the second mounting plate 103. A third mounting plate 105 is provided at the end of the hydraulic rod of the hydraulic device 104. A corresponding mounting sleeve 106 is rotatably mounted on the side ends of the third mounting plate 105 and the first mounting plate 102. A unwinding drum 107 is provided between the mounting sleeves 106. A motor for driving the unwinding drum 107, the winding shaft 109, and the cutter shaft 111 is provided on the first mounting plate 102. A rectangular opening is provided at the front end of the mounting sleeve 106. Both ends of the unwinding drum 107 are rectangular and are inserted into the rectangular opening. When installing the unwinding drum 107 with hot stamping foil, one end is inserted into the mounting sleeve 106 of the first mounting plate 102. Then, the hydraulic device 104 is activated, which moves the third mounting plate 105 toward the first mounting plate 102, allowing the other end of the unwinding drum 107 to also be inserted into the mounting sleeve 106, thereby completing the installation of the unwinding drum 107.

[0026] Furthermore, a first support member 1051 and a second support member 1052 corresponding to the take-up shaft 109 and the cutter shaft 111 are rotatably mounted on the side end of the third mounting plate 105. The ends of the take-up shaft 109 and the cutter shaft 111 are respectively inserted into the first support member 1051 and the second support member 1052. A limit strip is provided on the outer surface of the take-up shaft 109, and a limit groove corresponding to the limit strip is provided on the inner wall of the take-up drum 1091. The cutter shaft 111 is rectangular, and the blade 112 is a circular blade. A rectangular hole adapted to the cutter shaft 111 is opened at the center of the blade 112. When the third mounting plate 105 moves toward the first mounting plate 102, the ends of the take-up shaft 109 and the cutter shaft 111 can be inserted into the first support member 1051 and the second support member 1052 respectively. The first support member 1051 and the second support member 1052 can support the take-up shaft 109 and the cutter shaft 111 to ensure their rotational stability. The limiting strip provided on the outer surface of the take-up shaft 109 and the limiting groove provided on the inner wall of the take-up drum 1091 can cooperate. When the take-up shaft 109 rotates, the take-up drum 1091 can rotate with it to perform the winding work. Secondly, it is convenient for the take-up drum 1091 to move laterally on the take-up shaft 109, which facilitates the position adjustment and disassembly of the take-up drum 1091. The rectangular cutter shaft 111 and the blade 112 are set in the same principle.

[0027] It is worth noting that a mounting rod 110 is provided between the first mounting plate 102 and the second mounting plate 103. The mounting rod 110 has a movable opening, and a fixing member 204 is provided at the upper end of the dust collection box 203. The fixing member 204 is installed on the mounting rod 110 by bolts and nuts. The fixing member 204 is used to install the dust collection box 203 on the mounting rod 110, and the movable opening allows for easy adjustment of the position of the dust collection box 203 so that its position corresponds to the position of the blade 112.

[0028] It is worth mentioning that the upper end of the dust collection box 201 is equipped with a fan 202 that communicates with the dust collection box 201. A dust filter screen is installed at the connection between the fan 202 and the dust collection box 201. A sealable box door is rotatably installed at the rear end of the dust collection box 201. Air inlets are equidistantly arranged at the front end of the dust collection box 201. A negative pressure pipe 208 is installed at the upper end of the dust collection box 203. A connector 209 is installed at the end of the negative pressure pipe 208. The connector 209 is made of rubber and is inserted into the air inlet. The connector 209 is used to connect the dust collection box 203 to the dust collection bin 201. When the fan 202 is working, it can create negative pressure in the dust collection bin 201. The suction is transmitted to the dust collection box 203 through the negative pressure pipe 208, and the dust collection can be performed through the suction pipe 207. The dust collected can enter the dust collection bin 201, and the dust filter can prevent the dust from being discharged. When cleaning the dust in the dust collection bin 201, the door can be opened for cleaning.

[0029] It is worth noting that the dust collection box 203 is shaped with a smaller top and a larger bottom. First ball bearings 2031 are evenly spaced on the lower outer surface of the dust collection box 203, and these ball bearings 2031 contact the blade 112. A suction pipe 207 is located at the lower part of the dust collection box 203, with a suction port at its side end. The suction pipe 207 has a ring-shaped structure and surrounds the edge of the blade 112. A spring 205 is located at the upper side of the dust collection box 203, and a damping rod is installed inside the spring 205. The end of the spring 205 has a... The beveled grinding block 206 contacts the cutting edge of the blade 112. The dust collection box 203 located on both sides is also provided with a limiting rod 210 at its front end. The limiting rod 210 includes a first bend, a second bend, and a third bend along its long axis. The first bend bends outward at 90 degrees, the second bend bends downward at 90 degrees, and the third bend bends forward and is horizontally positioned. A second ball bearing 2101 is provided at the end of the limiting rod 210. The second ball bearing 2101 contacts the side ends of the take-up drum 1091 located on both sides. During the slitting process, the hot stamping foil is unwound from the unwinding drum 107, tensioned by the tensioning roller 108, slit by the blade 112, and finally wound up by the take-up drum 1091. During the slitting process, the dust collection box 203 can limit the movement of the blade 112. The setting of the first ball bearing 2031 does not affect the rotation of the blade 112. Secondly, the limit rod 210 can limit the movement of the take-up drum 1091, which can prevent relative movement between the blade 112 and the take-up drum 1091, ensuring its position and stability during the slitting and winding process. During the slitting process, under the compression of the spring 205, the grinding block 206 can contact the cutting edge of the blade 112, thereby grinding the blade 112 and preventing the blade 112 from wearing and producing burrs, which would cause uneven cuts. There is no need to frequently replace or adjust the blade 112, reducing the complexity and cost of operation.

[0030] Working Principle: This embodiment provides a dust-free hot stamping foil slitting device. In use, firstly, one end of the unwinding drum 107 containing hot stamping foil is inserted into the mounting sleeve 106 on the side of the first mounting plate 102. Then, the hydraulic device 104 is activated, causing its hydraulic rod to push the third mounting plate 105 towards the first mounting plate 102 until the other end of the unwinding drum 107 is inserted into the corresponding mounting sleeve 106 on the side of the third mounting plate 105, completing the installation of the unwinding drum 107. Simultaneously, during the movement of the third mounting plate 105, the ends of the winding shaft 109 and the cutting shaft 111 are respectively inserted into the first support member 1051 and the second support member 1052 on the side of the third mounting plate 105, achieving the connection of the winding shaft 109 and the cutting shaft 111. The support of 11; then, according to the slitting requirements, the position of the take-up drum 1091 on the take-up shaft 109 is adjusted by the cooperation of the limiting strip on the outer surface of the take-up shaft 109 and the limiting groove on the inner wall of the take-up drum 1091. The position of the blade 112 on the blade shaft 111 is adjusted by the cooperation of the rectangular blade shaft 111 and the central rectangular hole of the blade 112. Then, the position of the dust collection box 203 is adjusted by the movable port on the mounting rod 110 and the fixing part 204, so that the dust collection box 203 corresponds to the blade 112. At the same time, the rubber connector 209 at the end of the negative pressure tube 208 on the dust collection box 203 is inserted into the air inlet at the front end of the dust collection box 201. Subsequently, the hot stamping foil is released from the unwinding drum 107 and passes around the tensioning roller 108 in sequence for tensioning. The foil is then wound tightly around the corresponding take-up drum 1091 after passing through the blade 112. The motor is started, causing the take-up shaft 109 and the blade shaft 111 to rotate. The rotation of the take-up shaft 109 drives the take-up drum 1091 to rotate for winding, while the rotation of the blade shaft 111 drives the blade 112 to rotate and cut the foil. During the cutting process, the fan 202 at the top of the dust collection box 201 is started, creating negative pressure inside the dust collection box 201. This suction is transmitted to the dust collection box 203 through the negative pressure pipe 208. The dust collection pipe 207 at the bottom of the dust collection box 203 absorbs the dust generated by the blade 112 through the suction port. The dust enters the dust collection box 201 through the negative pressure pipe 208. The dust collection box 201 and... Dust filters at the connection point of the fan 202 block dust from being discharged by the fan 202. During the slitting process, the first ball bearing 2031 at the bottom of the dust collection box 203 contacts the blade 112 and limits its rotation without affecting it. The second ball bearing 2101 at the end of the limiting rod 210 at the front end of the dust collection box 203 on both sides contacts the side ends of the winding drum 1091 on both sides and limits the winding drum 1091 to prevent the blade 112 and the winding drum 1091 from moving relative to each other, thus ensuring the stability of slitting and winding. Under the compression of the spring 205, the grinding block 206 contacts the cutting edge of the blade 112 and grinds the rotating blade 112 to prevent it from having burrs due to wear, which would affect the slitting quality.After the slitting process is completed, turn off all drive mechanisms and the fan 202, and start the hydraulic equipment 104 to move the third mounting plate 105 away from the first mounting plate 102. Then, the take-up drum 1091 containing the slitting hot foil can be removed. Opening the rear door of the dust collection box 201 allows for cleaning of the collected dust.
