Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a rapid cold foil stamping reciprocating printing structure. Background Technology

[0002] Cold foil stamping is a printing process that uses special adhesive (ink) to adhere all parts of the foil stamping foil, except for the base layer, to the surface of the substrate, thus achieving the stamping effect. When assembling the roll (especially the foil material), the foil is generally thin to ensure a stable transfer of the intended design or text onto the printing material. However, its thinness makes it prone to damage and localized waste. The main issue is that the feeding of the foil material requires adjusting its relative spacing to ensure stable transport; however, existing adjustment methods are complex, impacting the printing efficiency of cold foil stamping. Utility Model Content

[0003] The main purpose of this invention is to propose a rapid cold foil stamping reciprocating printing structure, which aims to improve the existing printing structure and achieve stable transfer of cold foil stamping material. The structure is simple and stable, and can be adjusted according to the thickness of the cold foil stamping material.

[0004] To achieve the above objectives, this utility model proposes a rapid cold foil stamping reciprocating printing structure, comprising:

[0005] frame;

[0006] A feeding roller is used to mount the roll material and convey it forward. A first limiting roller is provided at a position above the feeding roller in the vertical direction. The first limiting roller switches between a position close to the upper wall of the feeding roller and a position away from the upper wall of the feeding roller.

[0007] The guide roller is provided with at least two sets, and a second limiting roller is provided at a position above the guide roller in the vertical direction. The second limiting roller switches between a position close to the upper wall of the guide roller and a position far away from the upper wall of the guide roller.

[0008] A pressure roller, located below the end guide roller, is used to press a predetermined pattern of the roll material onto the printing material;

[0009] A take-up roller is located in front of the pressure roller and is used to take up the processed roll material.

[0010] The roll material passes sequentially between the feeding roller and the first limiting roller, between the guide roller and the second limiting roller, between the lower end of the second limiting roller and the front wall of the pressure roller, until it extends to the upper wall of the take-up roller.

[0011] In the actual design, the cooperation of the first and second limiting rollers enables the guidance and conveying of the roll material, avoiding the problem of insufficient tension of the roll material. Furthermore, the thickness of the roll material can be appropriately adjusted by the first and second limiting rollers, ensuring both the tightness and the ability to adjust according to the thickness of the roll material, effectively improving the stability during cold stamping. Moreover, the staggered pressure rollers ensure that the printing mold of the pressure roller can stably cold stamp the predetermined pattern or text onto the printing material.

[0012] This enables high-speed transport of cold ironing materials while maintaining structural stability.

[0013] The printing structure can be installed as a standalone unit on existing printing conveyor equipment, or it can be designed as an integral part of the printing conveyor equipment, thereby increasing the versatility of the equipment design. Attached Figure Description

[0027] like Figures 1 to 3 As shown, a rapid cold foil stamping reciprocating printing structure includes:

[0028] Rack 1;

[0029] Feeding roller 2 is used to mount the roll 100 and convey it forward. A first limiting roller 61 is provided at the upper position of the feeding roller 2 in the vertical direction. The first limiting roller 61 switches between a position close to the upper wall of the feeding roller 2 and a position far away from the upper wall of the feeding roller 2.

[0030] The guide roller 3 is provided with at least two sets. A second limiting roller 62 is provided at the upper position of the guide roller 3 in the vertical direction. The second limiting roller 62 switches between a position close to the upper wall of the guide roller 3 and a position far away from the upper wall of the guide roller 3.

[0031] Pressure roller 4 is located below the end guide roller 3 and is used to press a predetermined pattern of the roll material onto the printing material.

[0032] The take-up roller 5 is located in front of the pressure roller 4 and is used to take up the processed roll material.

[0033] The roll material passes sequentially between the feeding roller 2 and the first limiting roller 61, between the guide roller 3 and the second limiting roller 62, between the lower end of the second limiting roller 62 and the front wall of the pressure roller 4, until it extends to the upper wall of the take-up roller 5.

[0034] In the actual design, the cooperation of the first limiting roller 61 and the second limiting roller 62 enables the guidance and conveying of the roll material, avoiding the problem of insufficient tension of the roll material. Furthermore, the thickness of the roll material can be appropriately adjusted by the first limiting roller 61 and the second limiting roller 62, ensuring its compression and allowing for adjustment according to the thickness of the roll material, effectively improving the stability during cold stamping. Moreover, the staggered pressure roller 4 ensures that the printing mold of the pressure roller 4 can stably cold stamp the predetermined pattern or text onto the printing material.

[0035] This enables high-speed transport of cold ironing materials while maintaining structural stability.

[0036] The printing structure can be installed as a standalone unit on existing printing conveyor equipment, or it can be designed as an integral part of the printing conveyor equipment, thereby increasing the versatility of the equipment design.

[0037] Specifically, the side walls on both sides of the frame 1 are provided with first slots 71, and first guide seats 72 are slidably installed in the first slots 71. The two ends of the first limiting roller 61 are pivotally installed between the two first guide seats. The upper end of the frame 1 is provided with a first driving device 73 for driving the first guide seats to slide vertically, thereby realizing the vertical adjustment of the first limiting roller 61.

[0038] In this embodiment of the utility model, the first driving device is a lead screw pair, a hydraulic cylinder, or a manual screw. The lead screw pair is existing technology and will not be described in detail here. Electric control is preferred.

[0039] Specifically, the side walls on both sides of the frame 1 are provided with second slots 81, and second guide seats 82 are slidably installed in the second slots.

[0040] In this embodiment of the invention, the second slot at the very end is inclined. Multiple sets of second limiting rollers 62 ensure stable conveying of the roll material, and the longer the roll, the faster the conveying speed.

[0041] The second slot at the end is inclined to ensure the smooth conveying of the roll material when it is tightened at the end, thus ensuring flatness.

[0042] Specifically, the second drive device is a lead screw pair, a hydraulic cylinder, or a manual screw.

[0043] In this embodiment of the present invention, one end of the feeding roller 2 extends out of the frame 1 and is connected to the first rotary motor, wherein the first rotary motor is connected to a reducer, thereby achieving precise control of the rotation speed.

A gear belt 9 is provided in a closed loop between the end guide roller 3, the pressure roller 4, the tensioning roller, and the drive end of the second rotary motor. The second rotary motor drives the end guide roller 3, the pressure roller 4, and the tensioning roller to rotate synchronously through the gear belt, thereby ensuring the synchronous conveying of the pressure roller 4 and the end roller.

[0045] In this embodiment of the utility model, the gear belt is sequentially attached to the outer peripheral wall of the last guide roller 3, the inner peripheral wall of the pressure roller 4, the outer peripheral wall of the drive end of the second rotary motor, and the outer rear wall of the tension roller, thereby ensuring the tension of the gear belt.
