Description

Technical Field

[0001] This invention relates to the field of hot stamping machine technology, and more specifically to an intelligent hot stamping device for shell surface treatment. Background Technology

[0002] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping electroplated aluminum foil onto the surface of a substrate under certain temperature and pressure. Hot stamping machines are the equipment that completes the hot stamping process. Existing hot stamping equipment can basically meet the needs of industrial production, but there are still some shortcomings that need to be improved.

[0003] In the production of cardboard packaging, text or patterns can also be processed on cardboard raw materials through hot stamping. This process uses flat hot stamping, where a hot stamping plate is used to press the hot stamping material. Typically, the hot stamping plate is heated to a high temperature and has a specified pattern on the processed surface. During continuous production, the hot stamping material moves close to the hot stamping plate, and each pressing creates a hollowed-out area. Therefore, it is easy for the hot stamping material to scratch or stick to the hot stamping plate during the transportation process. Thus, there is an urgent need for an intelligent hot stamping device for shell surface treatment to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent hot stamping device for housing surface treatment, so as to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smart hot stamping device for shell surface treatment includes a machine compartment and a conveying mechanism. A lifting platform is provided inside the machine compartment. The conveying mechanism is used to sequentially convey cardboard to the lifting platform. A heating chamber is provided above the lifting platform. An unwinding drum and a rewinding drum are respectively provided on two opposite sides outside the machine compartment. The hot stamping material unwound from the unwinding drum passes between the lifting platform and the heating chamber and is then wound onto the rewinding drum. The device also includes: a hot stamping plate, which is lifted and positioned at the bottom of the heating chamber; a swing arm, which is elastically rotatably connected to the heating chamber and automatically extends out from the bottom of the heating chamber; and a first linkage component, which is used to link the hot stamping plate and the swing arm. When the swing arm is pushed by the lifting platform, the hot stamping plate moves downward in linkage to imprint the hot stamping material.

[0007] Preferably, the first linkage component includes a rack disposed on the side wall of the hot stamping plate, and a gear meshing with the rack is coaxially connected to the pivot shaft of the rocker arm.

[0008] Preferably, two sets of swing arms are symmetrically arranged, respectively set on two opposite sides of the hot stamping plate corresponding to the hot stamping material conveying direction. Each set of swing arms has two swing arms spaced apart, and the spacing matches the width of the hot stamping material.

[0009] Preferably, two rolling chambers are arranged opposite each other on the outer side of the machine compartment, and the unwinding drum and the take-up drum are respectively arranged in one rolling chamber. Multiple auxiliary rollers for guiding hot stamping material are arranged in the rolling chamber.

[0010] Preferably, an adjusting roller is provided in the rolling chamber, and the hot stamping material between the two auxiliary rollers is arranged in a U-shape around the adjusting roller. A detection fork corresponding to the take-up drum is movably arranged in the rolling chamber. One end of the detection fork is in contact with the hot stamping material being wound on the take-up drum, while the other end is linked to the lifting and lowering of the adjusting roller through a second linkage component. As the take-up drum continuously winds up the hot stamping material, the detection fork moves to link the adjusting roller to rise.

[0011] Preferably, a support is provided inside the rolling chamber, and the rod of the detection fork is elastically and movably connected to the support.

[0012] Preferably, the second linkage component includes a linkage frame fixedly disposed at the end of the detection fork away from the winding drum, the linkage frame being provided with an inclined slide groove, a support arm being fixedly disposed on the adjusting roller, a sliding pin being provided at the upper end of the support arm and movably connected to the inclined slide groove, a support plate being disposed on the bracket, and the sliding pin being movably connected to the support plate in a lifting motion.

[0013] Preferably, the end of the sliding pin is provided with a guide block, and the support plate is provided with a guide groove that matches the guide block.

[0014] Preferably, the upper end of the guide groove is provided with a circular cavity, the guide block can be rotated after entering the circular cavity, and a slider is movably mounted on the support plate. The sliding pin rotates through the slider and is connected to the slider through a coil spring.

[0015] Preferably, the adjusting roller is positioned adjacent to one of the auxiliary rollers when it rises to its highest position.

[0016] In the above technical solution, the beneficial effects of the present invention are:

[0017] This intelligent hot stamping device for surface treatment of the housing features a liftable hot stamping plate and a rotating swing arm. Under the linkage of the first linkage component, when the lifting platform carries the cardboard upwards, it pushes the swing arm to extend beyond the free end of the heating chamber bottom, thereby causing the hot stamping plate to descend. The hot stamping material is then clamped between the lifting platform and the hot stamping plate, allowing it to be smoothly imprinted onto the cardboard. Subsequently, during the descent, the lifting platform separates from the swing arm, which rebounds and causes the hot stamping plate to rise again, thus keeping the hot stamping plate away from the hot stamping material. This prevents scratching or sticking during subsequent material transport and also avoids premature contact between the hot stamping material and the hot stamping plate, preventing overheating.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0033] Please see Figure 1-9 This invention provides an intelligent hot stamping device for shell surface treatment, comprising a machine compartment 1 and a conveying mechanism. A lifting platform 2 is provided inside the machine compartment 1. The conveying mechanism sequentially conveys cardboard onto the lifting platform 2. A heating chamber 3 is provided above the lifting platform 2. An unwinding drum 4 and a rewinding drum 5 are respectively provided on two opposite sides outside the machine compartment 1. The hot stamping material unwound from the unwinding drum 4 passes between the lifting platform 2 and the heating chamber 3 and is then wound onto the rewinding drum 5. The device also includes: a hot stamping plate 6, which is lifted and positioned at the bottom of the heating chamber 3; a swing arm 7, which is elastically rotatably connected to the heating chamber 3 and automatically extends from the bottom of the heating chamber 3; and a first linkage component, which links the hot stamping plate 6 and the swing arm 7. When the swing arm 7 is pushed by the lifting platform 2, the hot stamping plate 6 moves downwards to imprint the hot stamping material.

[0034] Specifically, the machine compartment 1 is equipped with a drive mechanism that raises and lowers the lifting platform 2. Both the drive mechanism and the conveying mechanism are controlled by a servo system. After the conveying mechanism accurately transfers the cardboard to the lifting platform 2, the conveying mechanism stops, the lifting platform 2 rises and falls once, and then the conveying mechanism removes the cardboard from the lifting platform 2 and transfers new cardboard to the lifting platform 2, thus repeating the cycle. The drive mechanism and conveying mechanism are existing technologies, and their specific structures are not described in detail and are omitted from the figure. The heating chamber 3 integrates a temperature control mechanism for maintaining the constant temperature of the hot stamping plate 6 and setting the hot stamping plate 6 at a designated height. The machine compartment 1 is equipped with a support shaft for supporting the unwinding drum 4 and the take-up drum 5. The support shaft is a spliced ​​structure and is detachable to facilitate the replacement of the unwinding drum 4 and the take-up drum 5. The take-up drum 5 is driven to rotate actively by the support shaft, while the unwinding drum 4 rotates passively with damping, thereby ensuring the tension on the hot stamping material. The two opposite side walls of the machine compartment 1 are provided with openings, which correspond to the height of the gap between the lifting platform 2 and the heating chamber 3. The hot stamping material enters and exits through the openings on both sides. The bottom of the heating chamber 3 is provided with a storage cavity, and the hot stamping plate 6 is movably mounted on the take-up drum. Inside the storage cavity, the lower processing surface of the hot stamping plate 6 can be raised and lowered to enter and exit the storage cavity; the pivot of the swing rod 7 is connected to the interior of the heating chamber 3 through elastic components such as torsion springs. The elastic rotation of the swing rod 7 allows it to automatically swing its free end downward and extend it out of the bottom surface of the heating chamber 3 without external force. When the lifting platform 2 rises and approaches the heating chamber 3, the free end of the swing rod 7 can be pushed by the lifting platform 2; the first linkage component is set so that when the free end of the swing rod 7 swings upward, the hot stamping plate 6 is linked to descend, and when the free end of the swing rod 7 swings downward, the hot stamping plate 6 is linked to rise. In practical use, when the lifting platform 2 carries the cardboard upward, the lifting platform 2 will push the swing rod 7 to extend out of the free end of the bottom surface of the heating chamber 3. The swing rod 7 rotates and, through the first linkage component, links the hot stamping plate 6 to descend. The hot stamping material can then be clamped between the lifting platform 2 and the hot stamping plate 6, allowing the hot stamping material to be smoothly imprinted onto the cardboard. Afterward, during the descent of the lifting platform 2, it separates from the swing rod 7. The swing rod 7 rebounds and links the hot stamping plate 6 to rise, thereby keeping the hot stamping plate 6 away from the hot stamping material. This prevents scratching or sticking during the subsequent conveying of the hot stamping material and also avoids premature contact between the hot stamping material and the hot stamping plate 6, which could cause overheating.

[0035] Compared with the prior art, the intelligent hot stamping device for shell surface treatment proposed in this embodiment of the invention is equipped with a liftable hot stamping plate 6 and a rotating swing rod 7. Under the linkage of the first linkage component, when the lifting platform 2 carries the cardboard upward, the lifting platform 2 will push the swing rod 7 to extend out of the free end of the bottom surface of the heating chamber 3, thereby linking the hot stamping plate 6 to descend. The hot stamping material can be clamped between the lifting platform 2 and the hot stamping plate 6, so that the hot stamping material can be smoothly imprinted on the cardboard. Afterward, the lifting platform 2 separates from the swing rod 7 during the descent. The swing rod 7 rebounds and links the hot stamping plate 6 to rise, thereby keeping the hot stamping plate 6 away from the hot stamping material. This prevents scratching or sticking during the subsequent hot stamping material transportation process and also avoids the hot stamping material from contacting the hot stamping plate 6 in advance, which would cause overheating.

[0036] As a preferred technical solution of this embodiment, the first linkage component includes a rack 8 provided on the side wall of the hot stamping plate 6, and a gear 9 coaxially connected to the rotating shaft of the swing arm 7 and meshing with the rack 8. Specifically, when the free end of the swing arm 7 swings upward, it drives the gear 9 to rotate, and the gear 9 meshes with the rack 8 to drive the hot stamping plate 6 to descend. When the free end of the swing arm 7 swings downward, the rack 8 similarly drives the hot stamping plate 6 to rise.

[0037] As a preferred technical solution in this embodiment, two sets of swing rods 7 are symmetrically arranged, respectively set on two opposite sides of the hot stamping plate 6 corresponding to the hot stamping material conveying direction. Each set of swing rods 7 has two swing rods spaced apart, and the spacing matches the width of the hot stamping material. Specifically, the swing rods 7 in the same set rotate synchronously. When the lifting platform 2 rises and pushes the swing rod 7, the swing rod 7 swings upward and moves the hot stamping plate 6 downward in conjunction with it, so as to achieve hot stamping smoothly. When the lifting platform 2 descends and leaves the swing rod 7, the swing rod 7 swings downward and moves the hot stamping plate 6 upward in conjunction with it. On the one hand, this prevents the hot stamping material from scratching, sticking, and overheating. On the other hand, the extended swing rods 7 are limited to the opposite sides of the hot stamping material, ensuring that the hot stamping material is always directly aligned with the hot stamping plate 6 during the processing.

[0038] As a preferred technical solution of this embodiment, two rolling chambers 10 are arranged opposite each other on the outer side of the machine compartment 1. The unwinding drum 4 and the take-up drum 5 are respectively arranged in one rolling chamber 10. Multiple auxiliary rollers 11 for guiding hot stamping material are arranged in the rolling chamber 10. Specifically, the support shafts of the unwinding drum 4 and the take-up drum 5 are also arranged in the rolling chamber 10. The axial direction of the auxiliary rollers 11 is parallel to the axial direction of the support shaft. There are no fewer than two auxiliary rollers 11 in the same rolling chamber 10.

[0039] As the rewinding cylinder 5 continuously rewinds the hot stamping material, its rewinding radius expands, thereby increasing the length of each rewind. Consequently, the embossing interval on the hot stamping material gradually increases, resulting in material waste. The following embodiments are proposed to address this issue.

[0040] In another embodiment of the present invention, an adjusting roller 12 is vertically mounted inside the rolling chamber 10. The hot stamping material between the two auxiliary rollers 11 is arranged in a U-shape around the adjusting roller 12. A detection fork 13 corresponding to the take-up drum 5 is movably mounted inside the rolling chamber 10. One end of the detection fork 13 is in contact with the hot stamping material being wound on the take-up drum 5, while the other end is linked to the lifting and lowering of the adjusting roller 12 via a second linkage component. As the take-up drum 5 continuously winds up the hot stamping material, the detection fork 13 moves to link the adjusting roller 12 upwards. Specifically, the axial direction of the adjusting roller 12 is parallel to the axial direction of the auxiliary rollers 11, and the height of the adjusting roller 12 does not exceed the height of the auxiliary rollers 11. The detection fork 13 includes a fork head and a rod. The detection fork 13 moves horizontally, and the fork head is V-shaped, allowing it to contact the outer wall of the hot stamping material roll being wound on the take-up drum 5. A bracket 14 is provided inside the rolling chamber 10, and the rod of the detection fork 13 is elastically and movably connected to the bracket 14. A rib groove is provided on the lower side of the rod, and a through hole matching the rod is provided on the bracket 14. A protrusion matching the rib groove is provided on the inner wall of the through hole. A spring is provided between the end of the inner wall of the rib groove near the fork head and the protrusion. A guide wire passing through the protrusion and the spring is provided in the rib groove. Thus, under the elastic force of the spring, the rod keeps driving the fork head close to the take-up drum 5. The second linkage component is provided so that when the take-up drum 5 continuously winds up the hot stamping material, and the radius of the hot stamping material roll on it continuously increases, the detection fork 13 is forced to move away from the axis of the take-up drum 5. At the same time, the adjusting roller 12 rises in linkage so that the length of the hot stamping material wrapped on the auxiliary roller 11 is reduced, thereby compensating for the increase in the winding length of the take-up drum 5 each time. After the hot stamping material on the take-up drum 5 is unwound, the detection fork 13 elastically resets to be close to the axis of the take-up drum 5. At the same time, the adjusting roller 12 falls in linkage so that the length of the hot stamping material wrapped on the auxiliary roller 11 is restored to store the allowance.

[0041] As a preferred embodiment, the second linkage component includes a linkage frame 15 fixedly disposed at the end of the detection fork 13 away from the take-up drum 5. The linkage frame 15 has an inclined slide groove 16. A support arm 17 is fixedly disposed on the adjusting roller 12. A sliding pin 18, movably connected to the inclined slide groove 16, is disposed at the upper end of the support arm 17. A support plate 19 is disposed on the bracket 14. The sliding pin 18 and the support plate 19 are movably connected in a lifting manner. Specifically, the end of the inclined slide groove 16 closest to the take-up drum 5 is positioned at a higher height. When the detection fork 13 moves the linkage frame 15 away from the take-up drum 5, the inclined slide 16 drives the sliding pin 18 to rise; the support arm 17 is provided at both ends of the adjusting roller 12, and the linkage frame 15 is provided on the outside of the support arm 17; the axial direction of the sliding pin 18 is parallel to the axial direction of the adjusting roller 12; the end of the sliding pin 18 is provided with a guide block 20, and the support plate 19 is provided with a guide groove 21 that matches the guide block 20. The guide block 20 only moves up and down within the guide groove 21, thereby limiting the support arm 17 from driving the adjusting roller 12 to move up and down.

[0042] As a further preferred technical solution of this embodiment, a circular cavity 22 is provided at the upper end of the guide groove 21. The guide block 20 can be rotated after entering the circular cavity 22. A slider 23 is movably mounted on the support plate 19. The sliding pin 18 rotates through the slider 23 and is connected to the slider 23 through the coil spring 24. Specifically, when the sliding pin 18 and the inclined slide groove 16 rise to the highest position in linkage, the sliding pin 18 drives the guide block 20 to separate from the guide groove 21 and completely enter the circular cavity 22. At this time, the guide block 20 rotates within the circular cavity 22. The sliding pin 18 is inserted into the circular cavity 22, thereby limiting the height of the sliding pin 18. The position of the linkage frame 15 is then limited by the inclined slide groove 16. Furthermore, the detection fork 13 is kept at the furthest position from the take-up drum 5, which facilitates the disassembly and assembly of the take-up drum 5. After the take-up drum 5 is disassembled and the hot stamping material is removed, the support arm 17 can be manually moved to rotate the sliding pin 18. The sliding pin 18 drives the guide block 20 to rotate to re-align with the guide groove 21. Thus, the sliding pin 18 can descend and the detection fork 13 can move back to its original position. The slider 23 moves up and down on the support plate 19 with the sliding pin 18. The coil spring 24 stores elastic potential energy when the sliding pin 18 has not risen to its highest position, causing the sliding pin 18 to tend to rotate relative to the slider 23. When the sliding pin 18 rises to its highest position, the guide block 20 is fully inserted into the circular cavity 22, and the elastic potential energy of the coil spring 24 is released, causing the sliding pin 18 to rotate relative to the slider 23. The guide block 20 also rotates with the sliding pin 18 and is locked into the circular cavity 22. This achieves automatic locking of the sliding pin 18 after it rises to its highest position. At this time, it is necessary to disassemble and reassemble the take-up drum 5 and remove the hot stamping material.

[0043] As a further preferred technical solution of this embodiment, when the adjusting roller 12 rises to the highest position, it is arranged adjacent to one of the auxiliary rollers 11. Specifically, the sliding pin 18 rotates under the elastic action of the coil spring 24, causing the support arm 17 to drive the adjusting roller 12 to swing closer to the adjacent auxiliary roller 11. In practical use, when the take-up drum 5 is wound to the specified size, the movement of the detection fork 13 is linked to the sliding pin 18 through the linkage frame 15 and the inclined slide groove 16 to rise to the highest position. On the one hand, the sliding pin 18 drives the adjusting roller 12 to rise to a height close to that of the adjacent auxiliary roller 11 through the support arm 17. On the other hand, the sliding pin 18 drives the guide block 20 to correspond to the height of the circular cavity 22. As a result, the elastic potential energy of the coil spring 24 is released, causing the sliding pin 18 to rotate relative to the slider 23. The sliding pin 18 drives the guide block 20 to rotate to fit into the circular cavity 22. On the other hand, the sliding pin 18 drives the support arm 17 to swing. The support arm 17 drives the adjusting roller 12 to approach the auxiliary roller 11 and cooperate to hold the hot stamping material between them. In this way, when the take-up drum 5 is disassembled later, one end of the cut hot stamping material can be automatically fixed between the adjusting roller 12 and the auxiliary roller 11 without the need for other means of fixing, which makes it convenient for the hot stamping material to be continued onto the take-up drum 5 later.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
