Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, specifically to an anti-wrinkle guide for hot stamping processing. Background Technology

[0002] Hot stamping is a process that uses heat transfer to transfer the aluminum layer from electroplated aluminum foil to the surface of the substrate, creating a special metallic effect. Because the main material used in hot stamping is electroplated aluminum foil, it is also called electroplated aluminum foil stamping. Anti-wrinkle guides are devices used to smooth out wrinkles in the substrate before hot stamping (mainly for paper and fabrics; materials like plywood and acrylic boards do not have wrinkles), preventing overlapping areas from affecting the hot stamping process.

[0003] A search revealed a Chinese utility model patent with publication number CN223116052U, which discloses an anti-wrinkle guide for hot stamping. The guide includes a horizontal plate and a square plate. The front and rear ends of the right side of the horizontal plate are fixedly connected to the left side of the square plate, respectively. A control structure is connected to the inner wall of the square plate, and a limiting structure is connected to the outer wall of the horizontal plate. A hot stamping machine is fixedly connected to the right side of the square plate, and a base is fixedly connected to the front of the square plate. The inner side of a ring is pressed against the outer wall of the support. Then, the motor is powered on, and the motor output shaft rotates the first cylinder. The rotating first cylinder, through a second cylinder, creates friction with the fixed object, causing the first and second cylinders to rotate in opposite directions, moving the object towards the hot stamping machine. This prevents wrinkles from forming during the object's movement, changing the manual anti-wrinkle method and improving the working efficiency of the anti-wrinkle guide for the hot stamping machine. However, the above solution also has the following shortcomings: the first cylinder is directly driven to rotate by the motor, and the second cylinder presses on the printing material from above. In this case, the second cylinder is actually driven to rotate passively by the friction of the printing material. To a certain extent, it can straighten the printing material, but the contact time between the printing material and the cylinder is very short, and it will recover its wrinkles after it leaves. Utility Model Content

[0004] The purpose of this invention is to provide an anti-wrinkle guide for hot stamping to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-wrinkle guide for hot stamping, comprising a mounting base and a motor. The mounting base is a rectangular box structure with an open bottom. A scissor-type telescopic frame is installed in the mounting base. Rollers are installed at the middle and lower hinge points of the scissor-type telescopic frame. Pulleys are installed at the ends of the rollers. Adjacent pulleys are connected by belts to achieve synchronous rotation of all rollers. An input shaft and a connecting rod are distributed at both ends of the upper side of the scissor-type telescopic frame. The input shaft passes longitudinally through the mounting base and is rotatably connected to it through a bearing. The mounting base has a longitudinally penetrating elongated hole. The end of the connecting rod passes through the elongated hole and is slidably connected to it. The position of the connecting rod in the elongated hole is adjusted by a limiting mechanism. The motor is fixedly installed on the side of the mounting base and docked with the end of the input shaft. A pulley is fixedly installed on the input shaft.

[0006] Preferably, L-shaped brackets are welded to the left and right sides of the mounting base.

[0007] Preferably, the roller is covered with a flexible rubber sleeve.

[0008] Preferably, the limiting mechanism includes a screw and a connecting block. The connecting block is installed in the middle of the connecting rod, the screw passes through one side of the mounting base and is screwed thereto, and the inner end of the screw is rotatably connected to the connecting block.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the printing material passes between the upper and lower rollers of this guide, and each pair of adjacent rollers rolls the printing material, applying a pair of opposite forces. The rolling path is long, which can effectively smooth out the wrinkles. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an anti-wrinkle guide for hot stamping, including a mounting base 2 and a motor 7. The mounting base 2 is a rectangular box structure with an open bottom. L-shaped brackets 4 are welded to the left and right sides of the mounting base 2. A scissor-type telescopic frame 1 is installed in the mounting base 2. Rollers 8 are installed at the middle and lower hinge points of the scissor-type telescopic frame 1. The rollers 8 are covered with flexible rubber sleeves. The rubber sleeves can increase friction when in contact with the printing substrate. Pulleys 9 are installed at the ends of the rollers 8. Adjacent pulleys 9 are connected by belts to achieve synchronous rotation of all rollers 8. The printing substrate passes between the two layers of rollers 8 to form a... Figure 4 The wavy shape shown is achieved by applying two opposing tangential forces to the paper through the upper and lower rollers 8, which helps to straighten and flatten it. Since there are multiple rollers 8, the folds are rolled multiple times, resulting in a good flattening effect.

[0017] The upper ends of the scissor-type telescopic frame 1 are equipped with input shafts 6 and connecting rods 10. The input shaft 6 extends longitudinally through the mounting base 2 and is rotatably connected to it via bearings. The motor 7 is fixedly mounted on the side of the mounting base 2 and docks with the end of the input shaft 6. A pulley 9 is fixedly mounted on the input shaft 6, which directly drives the nearest adjacent roller 8 to rotate. The mounting base 2 has a longitudinally extending elongated hole 3. The end of the connecting rod 10 extends through the elongated hole 3 and is slidably connected to it. A connecting block 11 is installed in the middle of the connecting rod 10. A screw 5 extends through one side of the mounting base 2 and is screwed to it. The inner end of the screw 5 is rotatably connected to the connecting block 11. The outer end of the screw 5 has a hexagonal head for rotation with a wrench. Rotating the screw 5 can adjust the lateral telescopic length of the scissor-type telescopic frame 1, thereby changing the relative position between the rollers 8, for example... Figure 4 In state a, the contact area between each roller 8 and the printing material is greater than in state b. A larger contact area means that the printing material can receive greater force and can better eliminate wrinkles. However, it is not always better to have a larger force. The tensile strength of the material also needs to be considered. Therefore, the guide is adjusted by setting a screw 5 to adapt to the actual situation.

[0018] Working principle: After the strip of printing material is pulled out, it passes through this guide. The printing material moves as follows within the guide... Figure 4 As shown in the wavy shape, the printing material contacts the circumferential surface of the roller 8 without creating new wrinkles. When the motor 7 is running, the two obliquely adjacent rollers 8 apply opposite tangential forces to the local area of ​​the printing material, and wrinkles can be eliminated after repeated stretching.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
