Description

Technical Field

[0001] This invention relates to the field of hot stamping technology, and more specifically, to a waste collection mechanism, hot stamping equipment, and hot stamping process. Background Technology

[0002] Cold foil stamping is a printing process that uses special adhesive to adhere all parts of the electroplated aluminum foil except the base film layer to the surface of the substrate, thus achieving the stamping effect. A cold foil stamping machine is an industrial device used to apply electroplated aluminum foil to the surface of the substrate. When the cold foil stamping machine is working, it first prints a special adhesive on the area of ​​the substrate that needs to be stamped. Then, under the pressure of the printing roller, the electroplated aluminum foil comes into contact with and is pressed together with the adhesive on the substrate surface. Finally, through a peeling operation, the part of the electroplated aluminum foil that needs to be transferred is transferred to the substrate to form the desired decorative effect. The base film layer of the used electroplated aluminum foil is recycled through a waste collection mechanism.

[0003] Before the waste collection process, the staff connects the end of the waste base film layer on the electroplated aluminum foil to the waste collection roller on the waste collection mechanism. During the hot stamping process, the waste collection roller will roll up and store the waste base film layer. In the existing technology, in order to adapt to different hot stamping needs, some waste collection mechanisms will be equipped with multiple waste collection rollers to collect the waste base film layers of multiple electroplated aluminum foils. However, when the staff installs multiple waste collection rollers, they usually install the waste collection rollers one by one, which is a rather cumbersome operation. Summary of the Invention

[0004] This invention provides a waste collection mechanism that overcomes the drawbacks of the cumbersome installation of multiple waste collection rollers in the prior art.

[0005] According to a waste collection mechanism of the present invention, the mechanism includes a frame body, the frame body including a connecting shaft mounted on a hot stamping machine, a plurality of waste collection rollers for winding waste base film layers sliding axially on the connecting shaft, the waste collection rollers being annular and having an inner annular surface; a first positioning groove is formed on the inner annular surface of the plurality of waste collection rollers corresponding to the connecting shaft, a limiting member for limiting the waste collection rollers and the connecting shaft sliding in the first positioning groove, and a through groove communicating with the first positioning groove is axially passed through both sides of the plurality of waste collection rollers; a limiting rod is commonly inserted into the through groove of the plurality of waste collection rollers, the limiting rod rotating in the through groove and squeezing and limiting the limiting member in the plurality of waste collection rollers.

[0006] Compared with existing technologies, the limiting rod can be rotated to squeeze and tighten the limiting components inside multiple waste collection rollers, avoiding the need to limit and install multiple waste collection rollers one by one, thus improving the installation efficiency of multiple waste collection rollers.

[0007] Preferably, the outer wall of the connecting shaft is provided with a guide groove along the axial direction, and the inner ring surface of the waste collection roller is fixed with a guide block for sliding in the guide groove, and the bottom side of the guide block is provided with a mating groove for the limiting member to slide.

[0008] In this invention, the guide block allows the limiting rod to be smoothly inserted into multiple waste collection rollers, thus facilitating the connection and assembly between the limiting rod and the multiple waste collection rollers.

[0009] Preferably, the bottom surface of the guide groove is provided with a plurality of second positioning grooves that cooperate with the limiting member along the sliding direction of the waste roller. The limiting member includes a positioning block that slides in the first positioning groove and passes through the docking groove and engages with the second positioning groove. The positioning block slides in the first positioning groove, and the rotating limiting rod makes the positioning block and the second positioning groove limit and abut against each other.

[0010] In this invention, the setting of the limiting rod can provide a thrust for the positioning block to engage with the second positioning groove, and can also continuously press the positioning block, thereby improving the stability of the engagement between the positioning block and the second positioning groove.

[0011] Preferably, the limiting member also includes a guide post provided on the inner wall of the first positioning groove along the sliding direction of the positioning block, an extension portion formed on the top of the positioning block that slides along the axial direction of the guide post, and a spring sleeved on the outer wall of the guide post for pushing the positioning block out of the second positioning groove.

[0012] In this invention, the spring allows the positioning block to disengage from the second positioning groove, thereby removing the limiting position between the multiple waste collection rollers and the connecting shaft, enabling rapid disassembly of the multiple waste collection rollers and further improving the disassembly and assembly efficiency of the device.

[0013] Preferably, the outer ring surface of the waste collection roller is provided with a third positioning groove that communicates with the through groove. An extension portion is fixed at one end of the outer ring surface of the waste collection roller in the third positioning groove. A clamping block that slides in the third positioning groove and abuts against the extension portion by rotating a limiting rod is also provided. The clamping block and the extension portion together constitute a limit for the end of the waste base film layer.

[0014] In this invention, by setting the limiting rod, the pressing block and the extension part are pressed together. The pressing block and the extension part press and fix the end of the waste base film layer located in the third positioning groove, thereby fixing the ends of multiple waste base film layers.

[0015] Preferably, the outer wall of the through groove is provided with anti-detachment grooves on both sides of the third positioning groove, and the anti-detachment groove is provided with an anti-detachment part on one side of the third positioning groove. The pressing block is formed to slide in the anti-detachment groove and contact the anti-detachment part.

[0016] In this invention, by setting the anti-detachment block, the anti-detachment part on the pressing block will slide in the anti-detachment groove and be blocked by the anti-detachment part, thereby preventing the pressing block from detaching from the third positioning groove.

[0017] Preferably, a positioning component for limiting the limiting rod is provided on the outer wall of the waste collection roller at both ends of the connecting shaft. The positioning component includes a fixed base fixed on both sides of the through groove and a positioning rod extending along the width direction at the fixed base to cooperate with the limiting rod.

[0018] In this invention, by setting the positioning element, the positioning rod can limit the rotation direction of the limiting rod, thereby improving the stability of the limiting rod's contact with the positioning block and the clamping block.

[0019] Preferably, the outer wall of the limiting rod is provided with multiple positioning holes that cooperate with the positioning rod for positioning along the connecting shaft.

[0020] In this invention, by setting multiple positioning holes, the positioning component on the waste collection roller can cooperate with the positioning holes at different positions on the limiting rod as needed, thereby limiting the limiting rod.

[0021] The present invention also provides a hot stamping device, which is equipped with the above-mentioned waste collection mechanism.

[0022] With the hot stamping equipment described above, the substrate is hot stamped, and the waste collection mechanism enables the rapid fixing of multiple waste base film layers by the waste collection rollers, thereby improving the installation efficiency of the waste collection mechanism of the hot stamping machine.

[0023] The present invention also provides a hot stamping process for the above-mentioned hot stamping equipment, comprising the following steps: S1: Install the waste collection mechanism on the hot stamping equipment; S2: Start the hot stamping equipment and print a special adhesive on the areas of the substrate that need hot stamping. The drying device of the hot stamping equipment reduces the moisture content in the adhesive. S3: The hot stamping machine's metal rollers bring the electroplated aluminum foil into contact with the adhesive. By applying pressure, the electroplated aluminum foil is firmly bonded to the surface of the substrate. The electroplated aluminum foil is then peeled off, and the peeled electroplated aluminum foil becomes a waste base film layer, which is recycled through a waste collection mechanism. S4: Apply a varnish or film to the surface of the printed material after hot stamping to protect the electroplated aluminum foil pattern.

[0024] The above-mentioned waste collection mechanism can be used to quickly install multiple waste collection rollers, thereby enabling the hot stamping machine to quickly collect multiple waste base film layers. Attached Figure Description

Detailed Implementation

[0026] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention. Example 1

[0027] like Figure 1-2 As shown, this embodiment provides a waste collection mechanism, which includes a frame body 100. The frame body 100 includes a connecting shaft 110 mounted on a hot stamping machine. Multiple waste collection rollers 120 for winding up waste base film layers slide axially on the connecting shaft 110. The waste collection rollers 120 are annular and have an inner annular surface. A first positioning groove 210 is provided on the inner annular surface of the multiple waste collection rollers 120 corresponding to the connecting shaft 110. A limiting member 230 for limiting the waste collection rollers 120 and the connecting shaft 110 slides in the first positioning groove 210. Through grooves 220 communicating with the first positioning groove 210 are axially passed through both sides of the multiple waste collection rollers 120. A limiting rod 130 is inserted into the through groove 220 of the multiple waste collection rollers 120. The limiting rod 130 rotates in the through groove 220 to squeeze and limit the limiting member 230 in the multiple waste collection rollers 120.

[0028] With the above structure, when installing multiple waste collection rollers 120, the workers install the multiple waste collection rollers 120 on the surface of the connecting shaft 110, and then insert the limiting rod 130 into the through groove 220 in the multiple waste collection rollers 120. By rotating the limiting rod 130 in the through groove 220, the limiting rod 130 squeezes the limiting member 230 in the first positioning groove 210, thereby limiting the limiting member 230 to the connecting shaft 110, realizing the rapid fixation of multiple waste collection rollers 120 to the connecting shaft 110. Compared with the prior art, by rotating the limiting rod 130, the limiting member 230 in the multiple waste collection rollers 120 can be squeezed and pressed, avoiding the need to limit the installation of multiple waste collection rollers 120 one by one, and improving the installation efficiency of multiple waste collection rollers 120.

[0029] (Additional explanation: The limiting rod 130 is made of steel, and the width of the limiting rod 130 is close to the diameter of the through groove 220, while the thickness of the limiting rod 130 is less than the diameter of the through groove 220.) Combination Figure 2-6 As shown, in this embodiment, a guide groove 140 is provided axially on the outer wall of the connecting shaft 110. A guide block 410 for sliding within the guide groove 140 is fixed on the inner annular surface of the waste collection roller 120. A docking groove 420 for the limiting member 230 to slide is provided on the bottom side of the guide block 410 located in the guide groove 140. Multiple second positioning grooves 310 cooperating with the limiting member 230 are provided on the bottom surface of the guide groove 140 along the sliding direction of the waste collection roller 120. The limiting member 230 includes a first positioning groove 210 that slides through and passes through the docking groove 420. The positioning block 430 engages with the second positioning groove 310. The positioning block 430 slides within the first positioning groove 210, and the rotating limiting rod 130 causes the positioning block 430 to be limited and pressed against the second positioning groove 310. The limiting member 230 also includes a guide post 710 provided on the inner wall of the first positioning groove 210 along the sliding direction of the positioning block 430. An extension 610 is formed on the top of the positioning block 430 that slides along the axial direction of the guide post 710. A spring 720 for pushing the positioning block 430 out of the second positioning groove 310 is sleeved on the outer wall of the guide post 710.

[0030] With the above structure, when the worker connects the waste collection roller 120 to the connecting shaft 110, the guide block 410 inside the waste collection roller 120 slides in the guide groove 140, thereby aligning the through grooves 220 of multiple waste collection rollers 120, so that the limiting rod 130 can be smoothly inserted into the multiple waste collection rollers 120, thus facilitating the connection and assembly between the limiting rod 130 and the multiple waste collection rollers 120; rotating the limiting rod 130 in the first positioning groove 210 changes the limiting rod 130 from horizontal to vertical, thereby squeezing the positioning block 430 out of the first positioning groove 210, so that the positioning block 430 slides towards the opening of the docking groove 420, thereby making the positioning block 430 engage with the second positioning groove 310, and at the same time, the limiting rod 130 after the change of direction will continue to press against the positioning block 430. The zero-tightening action ensures that the positioning block 430 remains inside the second positioning groove 310. This provides both a thrust for the positioning block 430 to engage with the second positioning groove 310 and a continuous tightening action, improving the stability of the engagement between the positioning block 430 and the second positioning groove 310. Rotating the limiting rod 130 again from vertical to horizontal releases the tightening action on the positioning block 430 within the multiple waste collection rollers 120. Simultaneously, the spring 720 outside the guide post 710 pushes the extension portion 610 within the positioning block 430, causing the positioning block 430 to disengage from the second positioning groove 310. This removes the limiting action between the multiple waste collection rollers 120 and the connecting shaft 110, enabling rapid disassembly of the multiple waste collection rollers 120 and further improving the assembly and disassembly efficiency of the device.

[0031] Combination Figure 6-8As shown, in this embodiment, the outer ring surface of the waste collection roller 120 is provided with a third positioning groove 620 that communicates with the through groove 220. An extension portion 630 is fixed at one end of the outer ring surface of the waste collection roller 120. A pressing block 640 slides in the third positioning groove 620 and abuts against the extension portion 630 by rotating the limiting rod 130. The pressing block 640 and the extension portion 630 together constitute a limiting position on the end of the waste base film layer. Anti-detachment grooves 650 are provided on both sides of the third positioning groove 620 on the outer wall of the through groove 220. An anti-detachment portion 660 is provided on one side of the third positioning groove 620. The pressing block 640 is formed as an anti-detachment block 670 that slides in the anti-detachment groove 650 and contacts the anti-detachment portion 660.

[0032] With the above structure, after the workers install multiple waste collection rollers 120 on the surface of the connecting shaft 110, they install the connecting shaft 110 on the hot stamping plate. Then, they place the ends of multiple waste base film layers into the third positioning grooves 620 of the multiple waste collection rollers 120 respectively. The limiting rod 130 is rotated from horizontal to vertical. While limiting the waste collection rollers 120 and the connecting shaft 110, the limiting rod 130 pushes the pressing block 640 to slide towards the opening of the third positioning groove 620, so that the pressing block 640 and the extension part 630 are pressed together. The pressing block 640 and the extension part 630 press and fix the ends of the waste base film layers located in the third positioning groove 620, thereby fixing the ends of multiple waste base film layers. At the same time, when the limiting rod 130 is removed from the waste collection rollers 120, the anti-detachment part 660 on the pressing block 640 will slide in the anti-detachment groove 650 and be blocked by the anti-detachment part 660, thereby preventing the pressing block 640 from being removed from the third positioning groove 620.

[0033] Combination Figure 1 , Figure 3 and Figure 9 As shown, in this embodiment, a positioning element 150 for limiting the positioning rod 130 is provided on the outer wall of the waste collection roller 120 at both ends of the connecting shaft 110. The positioning element 150 includes a fixed base 910 fixed on both sides of the through groove 220 and a positioning rod 920 extending along the width direction at the fixed base 910 to cooperate with the positioning rod 130. The outer wall of the positioning rod 130 is provided with a plurality of positioning holes 330 that cooperate with the positioning rod 920 for positioning along the axial direction of the connecting shaft 110.

[0034] With the above structure, after the limiting rod 130 is changed from horizontal to vertical, the positioning rod 920 on the positioning member 150 can limit the rotation direction of the limiting rod 130, thereby improving the stability of the limiting rod 130 in abutting the positioning block 430 and the pressing block 640. At the same time, when limiting different numbers of waste collection rollers 120, the positioning member 150 on the waste collection roller 120 can cooperate with the positioning holes 330 at different positions on the limiting rod 130 as needed, thereby limiting the limiting rod 130.

[0035] like Figure 1 As shown, the present invention also provides a hot stamping device, which includes the waste collection mechanism described in Embodiment 1.

[0036] With the hot stamping equipment described above, the substrate is hot stamped, and the waste collection mechanism enables the rapid fixing of multiple waste base film layers by the waste collection rollers 120, thereby improving the installation efficiency of the waste collection mechanism of the hot stamping machine. Example 2

[0037] like Figure 1 As shown, this embodiment utilizes the hot stamping equipment in Embodiment 1 for the hot stamping process, including the following steps: S1: Install the waste collection mechanism on the hot stamping equipment; S2: Start the hot stamping equipment and print a special adhesive on the areas of the substrate that need hot stamping. The drying device of the hot stamping equipment reduces the moisture content in the adhesive. S3: The hot stamping machine's metal rollers bring the electroplated aluminum foil into contact with the adhesive. By applying pressure, the electroplated aluminum foil is firmly bonded to the surface of the substrate. The electroplated aluminum foil is then peeled off, and the peeled electroplated aluminum foil becomes a waste base film layer, which is recycled through a waste collection mechanism. S4: Apply a varnish or film to the surface of the printed material after hot stamping to protect the electroplated aluminum foil pattern.

[0038] The above-mentioned waste collection mechanism can be used to quickly install multiple waste collection rollers 120, thereby enabling the hot stamping machine to quickly collect multiple waste base film layers.
