Abstract
Description
Technical Field
[0001] The utility model relates to hot stamping equipment, in particular to a paper conveying mechanism of a cold stamping machine. Background Art
[0002] In the printing industry, hot stamping is often used to achieve a metallic effect on printed materials. Hot stamping processes are categorized as hot stamping and cold stamping. Hot stamping involves engraving the desired pattern on a master plate and then applying heat to the gold and silver patterns on the anodized aluminum sheet, creating a three-dimensional effect. However, hot stamping has a significant drawback: it often breaks fine lines and produces incomplete or incomplete prints when stamping large areas. Cold stamping, on the other hand, involves gluing the pattern onto the gold-stamped anodized aluminum sheet, addressing these issues. Cold stamping requires a paper conveyor to transport the paper to the stamping station. However, friction during transport can cause slight deviations in the stamping position, compromising the stamping quality. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a paper conveying mechanism of a cold stamping machine, which can correct the deviation of paper during paper conveyance to prevent deviation of the stamping position.
[0004] In order to solve the above technical problems, the technical solutions adopted are as follows:
[0005] A paper conveying mechanism of a cold stamping machine includes a frame and a conveying device, which is installed on the frame and is characterized in that it also includes a detection device, a control device, two lateral pushing gauge devices and two longitudinal pushing gauge devices, the detection device, the control device, the lateral pushing gauge device and the longitudinal pushing gauge device are respectively installed on the frame, the detection device includes two detection sensors, and the two detection sensors are arranged side by side above the conveying device; the two lateral pushing gauge devices are respectively arranged on the left and right sides of the conveying device, and the pushing directions of the two lateral pushing gauge devices are arranged towards each other and are both perpendicular to the conveying direction of the conveying device; the two longitudinal pushing gauge devices are side by side, and the pushing directions of the longitudinal pushing gauge devices are parallel to the conveying direction of the conveying device; the signal output end of the detection device is electrically connected to the corresponding signal input end of the control device, and the signal input ends of the lateral pushing gauge device and the longitudinal pushing gauge device are respectively electrically connected to the corresponding signal output end of the control device.
[0006] In the aforementioned paper conveying mechanism, the detection device, lateral pusher device, and longitudinal pusher device are typically positioned in front of the paper hot stamping mechanism along the conveying direction of the conveying mechanism. During operation, the conveying mechanism conveys the paper. Before the paper is delivered to the paper hot stamping mechanism for hot stamping, the detection device first detects the paper (a color mark for cold stamping is printed on the paper, and the detection device detects the color mark) and transmits the detection result to the control device. If the paper position deviates, the control device calculates the offset on each side of the paper and calculates the corresponding push amount based on the offset. The control device then sends a control signal to the corresponding longitudinal pusher device, causing the longitudinal pusher device to push the paper to the corresponding position based on the push amount. Simultaneously, the control device sends a control signal to the two lateral pusher devices, which work together to correct the paper position in the left and right directions, thereby correcting the paper position. This paper conveying mechanism detects the paper position before hot stamping and corrects the paper deviation based on the detection results, ensuring that the desired hot stamping position of the paper is consistent with the offset plate and cold stamping anodized aluminum during hot stamping.
[0007] Typically, the two detection sensors of the detection device are arranged side by side above the rear end of the conveying device.
[0008] In the preferred embodiment, the longitudinal pushing gauge device includes a first correcting block, a lifting seat, a lifting drive mechanism capable of driving the lifting seat to lift and lower, a longitudinal translation seat and a longitudinal translation drive mechanism capable of driving the longitudinal translation seat to translate, the longitudinal translation drive mechanism is installed on the frame, the longitudinal translation seat is transmission-connected to the power output end of the longitudinal translation drive mechanism, the lifting drive mechanism is installed on the longitudinal translation seat, the lifting seat is transmission-connected to the power output end of the lifting drive mechanism, and the first correcting block is installed on the lifting seat; the signal input ends of the lifting drive mechanism and the longitudinal translation drive mechanism are respectively electrically connected to the signal output ends corresponding to the detection device.
[0009] The conveying device typically includes a conveying motor, a driving roller, a driven roller, and an endless belt. The motor is mounted on a lifting base, and the driving roller and driven roller are rotatably mounted on a frame. The driving roller is drivingly connected to the power output shaft of the conveying motor, and the driving roller and driven roller jointly tension the endless belt. The endless belt can be composed of multiple parallel endless belt units, with the driving roller being provided with multiple parallel driving pulleys, and the driven roller being provided with multiple parallel driven pulleys.

The driving pulleys and driven pulleys jointly tension the corresponding endless belt units. A gap is provided between adjacent endless belt units. Each first deflection correction block can be located in the gap between adjacent endless belt units. When deflection correction is required, the lifting drive mechanism drives the first deflection correction block to rise, allowing the first deflection correction block to pass through the gap and expose the endless belt. The longitudinal translation drive mechanism then drives the first deflection correction block to translate, causing it to push the paper.

The lateral translation drive mechanism is mounted on the frame, the lateral translation seat is in transmission connection with the power output of the lateral translation drive mechanism, and the second correcting block is mounted on the lateral translation seat.

The driving wheel is connected to the output shaft of the servo motor, the transmission belt is tensioned between the driving wheel and the driven wheel, and the longitudinal translation seat is installed on the forward section of the transmission belt.

The servo motor is mounted on a frame, and the driving pulley and driven pulley are rotatably mounted on the frame. The driving pulley is in driving connection with the output shaft of the servo motor. The transmission belt is tensioned between the driving pulley and the driven pulley, and the lateral translation seat is mounted on the forward section of the transmission belt. A pneumatic cylinder may also be employed in the lateral translation drive mechanism.

[0020] In the above-mentioned paper conveying mechanism, typically, the detection device 3, the lateral pusher device 4, and the longitudinal pusher device 5 are disposed in front of the paper hot stamping mechanism along the conveying direction of the conveying mechanism. During operation, the conveying mechanism 2 conveys the paper. Before the paper is conveyed to the paper hot stamping mechanism for hot stamping, the detection device 3 first detects the paper (a color mark for positioning cold stamping is printed on the paper, and the detection device 3 detects the color mark) and sends the detection result to the control device. If the position of the paper deviates, the control device calculates the offset on each side of the paper and calculates the corresponding push amount based on the offset on each side. The control device then sends a control signal to the corresponding longitudinal pusher device 5, causing the longitudinal pusher device 5 to push the paper to the corresponding position based on the push amount. At the same time, the control device sends a control signal to the two lateral pushers 4. The two lateral pushers 4 jointly correct the position of the paper in the left and right directions, thereby correcting the position of the paper. This paper conveying mechanism can detect the position of the paper before hot stamping and correct the paper according to the detection result, so as to ensure that the required hot stamping position of the paper is consistent with the offset plate and cold stamping electroplated aluminum when hot stamping.

When deflection correction is required, the lifting drive mechanism 503 drives the first deflection correction block 501 to rise, so that the first deflection correction block 501 passes through the gap and exposes the endless belt. Then the longitudinal translation drive mechanism 505 drives the first deflection correction block 501 to translate, so that the first deflection correction block 501 pushes the paper.

The second correcting block 401 of the left lateral push gauge device 4 moves rightward, while the second correcting block 401 of the right lateral push gauge device 4 moves leftward, respectively contacting the left and right edges of the paper, thereby jointly correcting the paper's position in the left and right directions.
