Description

Technical Field

[0001] This invention relates to the field of hot stamping foil processing, and more particularly to a hot stamping foil cutting mechanism for electronic product processing. Background Technology

[0002] Hot stamping foil, commonly known as electroplated aluminum foil, is a reflective material composed of multiple chemical coatings. It has a wide range of applications, particularly in the processing of electronic products, where it is commonly used for marking, insulation, and decoration. During processing, the required width of the hot stamping foil varies depending on the specific equipment used. Therefore, before processing, a cutting mechanism is typically used to cut the rolled hot stamping foil into several identical or different rolls.

[0003] Existing hot stamping foil cutting mechanisms typically use blades for cutting. When cutting with conventional blades, the depth of the cut is limited. Due to the thickness of the blade, the hot stamping foil may be squeezed. During deep cutting, friction and squeezing can cause the edges of the hot stamping foil to twist and become damaged. To solve this problem, existing technologies tend to design thin-blade cutting blades. By using thinner blades, the hot stamping foil roll is not squeezed and deformed during the cutting process due to the thickness of the blade. However, if the thickness of the thin-blade cutting blade is too low, it is prone to problems such as blade twisting and damage after long-term use, which affects the processing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution: A hot stamping foil cutting mechanism for electronic product processing includes: a frame, a rotatable mounting cylinder vertically fixed to the top of the frame, and an adjusting track that moves vertically along the inner side of the frame.

[0005] Specifically, a double-ended screw is provided on the inner side of the adjustment track. Two sets of retractable support components are threaded through the double-ended screw. A positioning plate is fixed at the end of the support component. The edge of the positioning plate is provided with an arc edge. A retractable cutting component is provided on one side of the positioning plate. The cutting component includes a cutting blade for cutting hot stamping foil.

[0006] As an improvement to the above technical solution, the frame is a horizontally arranged U-shaped structure, and a reinforcing rib is integrally formed on the other side of the recessed side of the frame. The mounting cylinder is located on the support plate above the frame, and the other end of the mounting cylinder is connected to a motor. The motor is mounted on the support plate of the frame.

[0007] As an improvement to the above technical solution, a track groove is provided on the recessed side of the frame, the end of the adjusting track is inserted into the inside of the track groove, and the end of the adjusting track is connected to a vertically arranged telescopic rod four, which is fixed inside the track groove. A disassembly groove is provided on the support plate on the side of the frame away from the motor, and the disassembly groove is used to remove the adjusting track along the track groove.

[0008] As an improvement to the above technical solution, the two sets of support components are telescopic rod one and telescopic rod two, respectively. The two ends of the double-ended screw pass through telescopic rod one and telescopic rod two, respectively. The distances from telescopic rod one and telescopic rod two to the thread boundary line of the double-ended screw are the same.

[0009] As an improvement to the above technical solution, the double-headed screw has a threaded extension rod three through it. The extension rod three is located on one side of the extension rod two. A positioning frame is fixed to the extension end of the extension rod three. A motor three is provided on one side of the positioning frame. The cutting blade is located inside the positioning frame. The power shaft of the motor three is connected to the shaft of the cutting blade through a synchronous belt.

[0010] As an improvement to the above technical solution, the two positioning plates are respectively fixed to the telescopic ends of telescopic rod one and telescopic rod two, and the two positioning plates are combined to form a circular plate, the radius of which is less than or equal to the radius of the mounting cylinder.

[0011] As an improvement to the above technical solution, the outer ring of the positioning plate is integrally formed with a baffle, and two baffles are combined to form a circular plate. The radius of the circular plate formed by the baffles is greater than or equal to the radius of the hot stamping foil roll fixed on the mounting cylinder.

[0012] As an improvement to the above technical solution, one of the positioning plates has a slot on its surface, and the other positioning plate has a support integrally formed on its surface. The support is inserted into the slot to form a smooth surface.

[0013] As an improvement to the above technical solution, one of the positioning plates has a slot 2 on its surface, and the other positioning plate has a support member 2 integrally formed on its surface. The support member 1 is inserted into the slot 1, and the support member 2 is inserted into the slot 2 to form a smooth surface.

[0014] As an improvement to the above technical solution, the cutting blade is a frustum-shaped blade, with the wide side of the cutting blade facing the first motor, and the end of the double-headed screw away from the frame is connected to the second motor, which is fixed to the outside of the adjustment rail.

[0015] The beneficial effects of this invention are: By setting the entire device vertically, and using a positioning plate with curved edges to provide bottom support, and assisting the cutting components to achieve the cutting function, the curved edges of the bottom support ensure that the pressure from the blade is transmitted to the edge during the cutting process. The pressure transmitted to the edge causes the hot foil layer at the edge to move towards the curved edge. The presence of the curved edge provides space for movement, so the cut hot foil sheet will slowly move down along the curved edge from the cut position. This design prevents the hot foil from being twisted or damaged by the pressure even if the cutting blade is thick. Attached Figure Description

Detailed Implementation

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] Existing hot stamping foil cutting mechanisms typically use blades for cutting. When cutting with conventional blades, the depth of the cut is limited. Due to the thickness of the blade, the hot stamping foil may be squeezed. During deep cutting, friction and squeezing can cause the edges of the hot stamping foil to twist and become damaged. To solve this problem, existing technologies tend to design thin-blade cutting blades. By using thinner blades, the hot stamping foil roll is not squeezed and deformed during the cutting process due to the thickness of the blade. However, if the thickness of the thin-blade cutting blade is too low, it is prone to problems such as blade twisting and damage after long-term use, which affects the processing.

[0020] To resolve the above issues, please refer to Figures 1 to 6 A hot stamping foil cutting mechanism for electronic product processing is provided, comprising: a frame 10, a rotatable mounting cylinder 20 vertically fixed to the top of the frame 10, and an adjusting track 30 that moves vertically along the inner side of the frame 10.

[0021] Specifically, a double-ended screw 302 is provided on the inner side of the adjusting track 30. Two sets of retractable support components 31 are threaded through the double-ended screw 302. A positioning plate 313 is fixed at the end of the support component 31. An arc edge 314 is provided on the edge of the positioning plate 313. A retractable cutting component 32 is provided on one side of the positioning plate 313. The cutting component 32 includes a cutting blade 323 for cutting hot stamping foil.

[0022] The positioning plate 313 is extended and retracted by the support component 31, while the double-headed screw 302 controls the lateral movement of the positioning plate 313. In normal state, the positioning plate 313 is in an unfolded state, and the edge of the positioning plate 313 is attached to the edge of the hot foil roll on the mounting cylinder 20. In this way, the hot foil roll is supported by the positioning plate 313 and will not fall off. During the cutting process of the cutting component 32, the two positioning plates 313 move inward synchronously through the double-headed screw 302. In this way, the outermost hot foil layer being cut is always in contact with the arc edge 314 during the cutting process. When the cutting blade 323 squeezes, due to the presence of the arc edge 314, the squeezed hot foil layer will move outward directly with a small movement, without excessive contact with the cutting blade 323 of the cutting component 32, thereby avoiding the problem of hot foil twisting and damage during the cutting process.

[0023] In one embodiment, for further refinement of the structure of the frame 10, please refer to [reference needed]. Figure 1 Specifically, the frame 10 has a horizontally arranged U-shaped structure. A reinforcing rib 12 is integrally formed on the other side of the recessed side of the frame 10. The mounting cylinder 20 is located on the support plate above the frame 10. The other end of the mounting cylinder 20 is connected to a motor 21, which is mounted on the support plate of the frame 10.

[0024] The U-shaped frame 10 provides overall fixation. Since the cutting assembly 32 can adopt many types of cutting structures, it is divided into two types: one where the hot foil being cut does not need to rotate and the cutting assembly 32 can cut around it; and the other where the hot foil needs to rotate on its own. The cutting blade 323 of the cutting assembly 32 only cuts in a single position. If it is a design that can cut around it, then there is no need to consider the structural design of the mounting cylinder 20. However, if it is cut in a single position, then it is necessary to ensure that the mounting cylinder 20 can rotate. Therefore, in this embodiment, the mounting cylinder 20 is rotated by a motor 21 to ensure that the cutting blade 323 can complete the circular cutting operation.

[0025] To further ensure the detachability of the structural components, in one embodiment, a track groove is provided on the recessed side of the frame 10, the end of the adjusting track 30 is inserted into the inside of the track groove, and the end of the adjusting track 30 is connected to a vertically arranged telescopic rod 33, which is fixed inside the track groove. A disassembly groove 11 is provided on the support plate on the side of the frame 10 away from the motor 21, and the disassembly groove 11 is used to remove the adjusting track 30 along the track groove.

[0026] The installation is achieved by setting a track groove on the inner side of the frame 10. The support of the overall structural components is provided by the set telescopic rod 33. When disassembling, all structural components connected to the adjustment track 30 are pushed out from the disassembly groove 11 at the bottom by the telescopic rod 33. When disassembling, the entire frame 10 needs to be tilted or lifted to ensure that it can be disassembled normally from the disassembly groove 11.

[0027] To further improve the technical solution, it is necessary to ensure that the support component 31 can accurately control the extension and retraction. In this embodiment, specifically, the two sets of support components 31 are telescopic rod one 311 and telescopic rod two 312, and the two ends of the double-headed screw 302 pass through telescopic rod one 311 and telescopic rod two 312 respectively.

[0028] The positioning plate 313 is controlled by two telescopic rods. After the cutting is completed, the cutting hot foil roll is de-supported by retracting the positioning plate 313. At this time, the cutting hot foil roll can be removed directly. It can be removed manually or by adding additional unloading claws.

[0029] Furthermore, to ensure synchronized control of the two telescopic rods by the double-ended screw 302, the distances from telescopic rod one 311 and telescopic rod two 312 to the thread boundary line of the double-ended screw 302 must be the same. This ensures accurate control of the unfolding and merging operations during adjustment. Both telescopic rod one 311 and telescopic rod two 312 are located inside the adjusting track 30, which forms a steering constraint, thus creating a functional structure similar to a lead screw track.

[0030] In the aforementioned technical solution, no restrictions were placed on the cutting component 32. In this embodiment, in order to further improve the technical solution, specifically, the double-headed screw 302 is threaded through the telescopic rod 321. The telescopic rod 321 is located on one side of the telescopic rod 312. The telescopic end of the telescopic rod 321 is fixed with a positioning frame 322. A motor 324 is provided on one side of the positioning frame 322. The cutting blade 323 is located inside the positioning frame 322. The power shaft of the motor 324 is connected to the shaft of the cutting blade 323 through a synchronous belt.

[0031] The additional telescopic rod 321 is installed to ensure that it moves synchronously with the telescopic rod 312. In this way, when cutting, the movement of the positioning plate 313 is synchronized with the movement of the cutting blade 323, thereby ensuring that the outermost hot stamping foil layer that has just been cut can stably contact the curved edge 314, and can always contact the curved edge 314 during the cutting process.

[0032] In the aforementioned technical solution, if the positioning plate 313 is not subject to any restrictions, the inner hot stamping foil may not be able to complete a stable cut. To avoid this problem, the following restrictions are imposed: Two positioning plates 313 are fixed to the telescopic ends of telescopic rod 1 311 and telescopic rod 2 312 respectively. The two positioning plates 313 are combined to form a circular plate, the radius of which is less than or equal to the radius of the mounting cylinder 20.

[0033] The two positioning plates 313 are designed to form a circle when combined, thus matching the shape of the mounting cylinder 20. Based on this, as long as the center of the final circular plate is on the same axis as the mounting cylinder 20, and its radius is less than or equal to the radius of the mounting cylinder 20, the cutting blade 323 can complete the cutting of all the hot foil on the mounting cylinder 20. In the aforementioned technical solution, if the thickness of the entire hot foil roll is too high, the weight of the hot foil being cut may be too great, leading to tearing due to gravity. To avoid this problem, the following design is provided: The outer ring of the positioning plate 313 is integrally formed with a baffle 319. The two baffles 319 are combined to form a circular plate. The radius of the circular plate formed by the baffles 319 is greater than or equal to the radius of the hot stamping paper roll fixed on the mounting cylinder 20.

[0034] By setting baffle 319 to provide support at the bottom, although there is a height difference between the thin arc edge 314 and baffle 319, this height difference is very small and will not cause the hot stamping foil to be twisted or torn. In this embodiment, the cutting blade 323 is a frustum-shaped blade, with the wide side of the cutting blade 323 facing the motor 1 21. The end of the double-headed screw 302 away from the frame 10 is connected to the motor 2 301, and the motor 2 301 is fixed to the outside of the adjustment rail 30.

[0035] like Figure 5 and Figure 6 As shown, the wide side refers to the side of the cutting blade 323 with a larger area. Its surface is flat, so it can serve as a support. The other side has a sloping surface, which will naturally compress downwards during cutting. This not only ensures that the cutting blade 323 can support other uncut hot stamping paper rolls after cutting, but also separates the uncut and cut parts during the cutting process.

[0036] After each cut, the cut foil roll falls onto baffle 319. At this time, telescopic rod 1 311 and telescopic rod 2 312 retract simultaneously. The operator can then manually remove the cut foil roll or use the additional grippers to remove it. After the material is removed, telescopic rod 1 311 and telescopic rod 2 312 are extended again and simultaneously opened. Under the influence of gravity, the entire foil roll descends and falls onto positioning plate 313, and the next cutting action begins.

[0037] In one embodiment, see Figures 1 to 3 One of the positioning plates 313 has a slot 316 on its surface, and the other positioning plate 313 has a support member 315 integrally formed on its surface. The support member 315 is inserted into the slot 316 to form a smooth surface. Since the hot stamping foil roll is cylindrical, the overall stability can be ensured by applying support through the positioning plates 313 on both sides. The support member 315 and the slot 316 set in the middle are used to position the two separate positioning plates 313 and avoid the problem of uneven force on the two telescopic rods caused by squeezing, which would prevent the two positioning plates 313 from being kept on the same plane. The connection between the support member 315 and the slot 316 can balance the force on both, thereby ensuring the stability of the structural components.

[0038] In one embodiment, see Figures 1 to 3 One of the positioning plates 313 has a slot 318 on its surface, and the other positioning plate 313 has a support member 317 integrally formed on its surface. The support member 315 is inserted into the slot 316, and the support member 317 is inserted into the slot 318 to form a smooth surface.

[0039] In this embodiment, the interlocking of multiple structural components enables the overall structure to form a stable connection, thus ensuring structural stability.

[0040] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
