Description

Technical Field

[0001] The invention relates to the technical field of hot stamping, in particular to a control system capable of realizing forward hot stamping and reverse hot stamping. Background Art

[0002] Hot stamping machine is a mechanical device specially used for hot stamping on paper, cardboard or other materials. It forms patterns and texts with metallic luster by transferring metal foil to the surface of the target material under the action of high temperature and pressure. In today's packaging printing, paper decoration, and even many high-end product label production fields, hot stamping technology undoubtedly plays a key role as a mainstay. Hot stamping machine is the core equipment that transforms this exquisite technology into real results. The quality of its foil release system is closely related to the quality of the hot stamping products and production efficiency.

[0003] Existing traditional hot stamping machines have great limitations in foil placement. Most of them can only achieve foil placement in a single direction, and reverse foil placement is the most common. However, with the rapid development of the times, market demand has become increasingly diverse and complex, and this single foil placement mode has become increasingly inadequate, exposing a series of problems that need to be solved urgently. From the perspective of product process accuracy, when encountering hot stamping tasks that incorporate complex design elements and have special-shaped structures, the forward foil placement mechanism becomes stretched. It is difficult to cleverly and accurately follow the ever-changing direction of the hot stamping parts. This is reflected in the hot stamping products, that is, the lack of gold and silver in some areas, which has a great impact on the aesthetics of the product and the added value has also been greatly reduced. Switching to the perspective of the production process, the flexibility is insufficient. The disadvantages are also significant. In actual production scenarios, the process requirements of different batches of products are often very different and frequently alternate. For example, a batch of products that have just completed forward pattern hot stamping will need reverse foil placement immediately afterwards. However, in the face of this situation, the traditional one-way foil hot stamping machine can only press the stop button helplessly, and even have to purchase corresponding equipment again, or reluctantly give up such orders, increasing costs helplessly. In summary, in the face of these difficulties and pain points, the research and development of forward and reverse foil placement technology of the foil placement system of the hot stamping machine is urgent. Only by overcoming this technical difficulty can we truly meet the modern manufacturing industry's eager desire and rigid demand for high-precision, high-flexibility, and low-cost hot stamping technology, inject new vitality into related industries, and open a new chapter of development.

[0004] Therefore, we propose a control system that can realize forward pulling and reverse pulling in order to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a control system that can realize forward and reverse foil pulling, so as to solve the problem that most hot stamping machines mentioned in the above background technology cannot realize forward and reverse switching of foil release according to production needs, which reduces practicality.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a control system that can realize forward gold pulling and reverse gold pulling, comprising a PLC control unit, a forward control unit, a reverse control unit, a drive unit and a tension detection unit, wherein the PLC control unit is used to monitor the system operation status in real time and quickly respond to various instructions, the forward control unit is used to control the forward foil release of the hot stamping machine, and the reverse control unit is used to control the reverse foil release of the hot stamping machine.

[0007] Preferably, the driving unit is used to drive the hot stamping machine to operate normally, and the tension detection unit is used to detect whether the foil tension is stable.

[0008] Preferably, it also includes: a control device for realizing forward gold pulling and reverse gold pulling, which includes: a foil placing machine casing, a driving motor is fixedly mounted on the outer surface of the foil placing machine casing by screws, and a coupling is fixedly connected to the output end of the driving motor.

[0009] Preferably, a forward and reverse foil-releasing shaft is arranged inside the foil-releasing machine housing, a material-releasing driving shaft is arranged near the center inside the foil-releasing machine housing, and a first guide roller is arranged inside the foil-releasing machine housing.

[0010] Preferably, a second guide roller is arranged inside the foil unloading machine housing, a hot stamping feed roller is arranged near the bottom inside the foil unloading machine housing, and a hot stamping discharge roller is arranged near the output end inside the foil unloading machine housing.

[0011] Preferably, a third guide roller is arranged inside the foil unloading machine casing near one side edge, a fourth guide roller is arranged inside the foil unloading machine casing, and a guide roller and a rotating sleeve are arranged inside the foil unloading machine casing near the top.

[0012] Preferably, a guide roller body and a rotating sleeve are arranged inside the foil unloading machine housing, and a material receiving driving shaft is arranged near the top center position inside the foil unloading machine housing.

[0013] Preferably, a fifth guide roller is arranged inside the foil unloading machine housing, and a sixth guide roller is arranged inside the foil unloading machine housing.

[0014] Preferably, a seventh guide roller is arranged inside the foil unwinding machine housing near the other outer surface, an internal gold collecting roller is arranged inside the foil unwinding machine housing, and a forward and reverse foil unwinding roller is arranged inside the foil unwinding machine housing.

[0015] Preferably, a material discharging active roller is arranged inside the foil discharging machine housing, an eighth guide roller is arranged inside the foil discharging machine housing, and a ninth guide roller is arranged inside the foil discharging machine housing.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During the foil discharge process of the hot stamping machine, when the foil needs to be discharged in the forward direction, the PLC control unit first sends out a command to transmit the signal to the forward control unit, and the driving unit drives the hot stamping machine to discharge the foil in the forward direction. When the hot stamping machine needs to discharge the foil in the reverse direction, the reverse control unit can be used to drive the hot stamping machine to discharge the foil in the reverse direction, which solves the problem that most hot stamping machines in the prior art cannot realize forward and reverse switching of foil discharge according to production needs, reducing practicality.

[0018] 2. During the process of foil discharge in the forward and reverse directions of the hot stamping machine, when the tension detection unit detects that the tension of the foil is too large, the signal can be transmitted to the drive unit through the PLC control unit to reduce the speed of the drive motor and reduce the amount of foil discharge. When the tension detection unit detects that the tension of the foil is too small, the signal can be transmitted to the drive unit through the PLC control unit to increase the speed of the drive motor and increase the amount of foil discharge. In this way, the foil tension can be accurately controlled when the foil is discharged in the forward and reverse directions, and the tension fluctuation is kept within a very small range to prevent the foil from breaking or relaxing and affecting the hot stamping effect.

[0019] 3. During the use of the hot stamping machine, the foil is first placed on the foil placing shaft through the pressure wheel on the foil placing machine housing. When the foil needs to be placed in the forward direction, the drive motor is first started through the external PLC control unit, so that the drive motor drives the coupling to rotate forward, thereby realizing the clockwise rotation of the foil placing shaft. When the foil needs to be placed in the reverse direction, the drive motor can be rotated in the reverse direction, thereby realizing the reverse direction foil placing of the hot stamping machine and the switching of the forward and reverse foil placing of the hot stamping machine, further improving the forward and reverse switching of the hot stamping machine, achieving the requirements of multiple uses of a hot stamping machine and meeting the requirements of one-key switching between forward and reverse foil placing.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 6 The present invention provides a technical solution: a control system that can realize forward and reverse gold pulling, including a PLC control unit 23, a forward control unit 24, a reverse control unit 25, a drive unit 26 and a tension detection unit 27. The PLC control unit 23 is used to monitor the system operation status in real time and quickly respond to various instructions. The forward control unit 24 is used to control the forward foil release of the hot stamping machine, and the reverse control unit 25 is used to control the reverse foil release of the hot stamping machine.

[0030] In this embodiment, the present invention is improved on the original basis of the foil placing system of the hot stamping machine, and a forward control unit 24 and a reverse control unit 25 are added. In the process of placing foil by the hot stamping machine, the foil is first placed on the foil placing shaft through the pressure wheel. When the foil needs to be placed forward, the PLC control unit 23 first sends an instruction to the outside, and transmits the signal to the forward control unit 24. The forward control unit 24 receives the signal and transmits the signal to the driving unit 26. The forward and reverse foil placing rollers 16 and the material placing active roller 17 arranged inside the hot stamping machine are driven by the driving unit 26 to rotate clockwise, so that the hot stamping machine can place foil forward. When the hot stamping machine needs to place foil in the reverse direction, the PLC control unit 23 sends an instruction to the outside again, and transmits the signal to the reverse control unit 2 5. The reverse foil discharge of the hot stamping machine can be realized by controlling the driving unit 26 to rotate counterclockwise by the reverse control unit 25. In addition, when the hot stamping machine is driven by the driving unit 26, the PLC control unit 23 uses the PID control algorithm to adjust the rotation speed of the driving unit 26 in real time according to the signal fed back by the tension detection unit 27, so as to keep the tension of the foil stable. When the tension detection unit 27 detects that the tension of the foil is too large, the signal is transmitted to the PLC control unit 23. The PLC control unit 23 receives the signal and sends an instruction to the outside to transmit it to the driving unit 26. The driving unit 26 receives the signal and automatically reduces the rotation speed of the driving motor 20 to reduce the discharge amount of the foil. When the tension detection unit 27 detects that the tension of the foil is too large, the PLC control unit 23 automatically reduces the rotation speed of the driving motor 20 to reduce the discharge amount of the foil. When the tension of the foil is too small, the tension detection unit 27 transmits a signal to the PLC control unit 23. The PLC control unit 23 receives the signal transmitted by the tension detection unit 27, issues an instruction to the outside, and transmits the signal to the drive unit 26. The drive unit 26 receives the signal, increases the rotation speed of the drive motor 20, and increases the discharge amount of the foil. The forward and reverse foil discharge systems of the hot stamping machine are integrated with the production process of the entire hot stamping machine to achieve automation. During the production process, when it is necessary to perform forward foil discharge, the PLC control unit 23 will start the drive motor 20 according to the preset process parameters, discharge the foil according to the set speed and tension, and synchronize with the movement of the hot stamping roller to ensure the consistency of the hot stamping effect. When it is necessary to perform reverse foil discharge, the foil discharge can be switched. direction, adjust relevant parameters to achieve a smooth transition. The forward and reverse foil release system of this hot stamping machine is designed to meet the needs of diversified hot stamping processes, realize accurate and stable foil release operations in the forward and reverse directions, improve the quality of hot stamping and production efficiency, and solve the problem that most hot stamping machines in the prior art cannot realize forward and reverse switching of foil release according to production needs, which reduces practicality. In addition, the hot stamping machine can quickly and smoothly realize the conversion from forward foil release to reverse foil release, and the conversion process has little effect on the continuity of hot stamping. When releasing the foil in the forward and reverse directions, the foil tension can be accurately controlled to keep the tension fluctuation within a very small range, prevent the foil from breaking and relaxing and affecting the hot stamping effect, ensure high-precision control of the foil release length, and meet the strict requirements of fine hot stamping patterns on the amount of foil.

[0032] In this embodiment, during the use of the hot stamping machine, the foil is first placed on the foil placing shaft through the pressure wheel of the foil placing machine housing 22. When the foil needs to be placed in the forward direction, the drive motor 20 is first started through the external PLC control unit 23, so that the drive motor 20 drives the coupling 21 to rotate forward, thereby making the forward and reverse foil placing shaft 1, the forward and reverse foil placing roller 16, the material placing active roller 17, the material placing active shaft 2, the hot stamping feed roller 5, the first guide roller 3, the second guide roller 4, the third guide roller 7, the fourth guide roller 8, the fifth guide roller 12, the sixth guide roller 13, the seventh guide roller 14, the eighth guide roller 18, the ninth guide roller 19, the internal gold collecting roller 15, the guide rollers and the rotating sleeve 9, the guide roller body and the rotating sleeve 10, the hot stamping discharge roller 6 and the material receiving active shaft 11 rotate clockwise, thereby realizing the forward foil discharge of the hot stamping machine.

[0033] The use method and working principle of this device: In the process of foil discharge of the hot stamping machine, the foil is first placed on the foil discharge shaft through the pressure wheel. When the foil needs to be discharged in the forward direction, the PLC control unit 23 first sends out a command to transmit the signal to the forward control unit 24. The forward control unit 24 receives the signal and transmits the signal to the drive unit 26. The drive unit 26 drives the forward and reverse foil discharge rollers 16 and the material discharge active roller 17 arranged inside the hot stamping machine to rotate clockwise, so that the hot stamping machine can discharge the foil in the forward direction. When the hot stamping machine needs to discharge the foil in the reverse direction, the PLC control unit 23 sends out a command again to transmit the signal to the reverse control unit 25. The reverse control unit 25 controls the drive unit 26 to rotate counterclockwise, and hot stamping can be achieved.

When the tension detection unit 27 detects that the tension of the foil is too large, the signal is transmitted to the PLC control unit 23. The PLC control unit 23 receives the signal and sends an instruction to the driving unit 26. The driving unit 26 receives the signal and automatically reduces the rotation speed of the driving motor 20 to reduce the amount of foil discharged. When the tension detection unit 27 detects that the tension of the foil is too small, the tension detection unit 27 transmits the signal to the PLC control unit 23. The PLC control unit 23 receives the signal transmitted by the tension detection unit 27, issues a command to the outside, and transmits the signal to the drive unit 26. The drive unit 26 receives the signal, increases the rotation speed of the drive motor 20, and increases the amount of foil material discharged. The forward and reverse foil discharge systems of the hot stamping machine are integrated with the production process of the entire hot stamping machine to achieve automation. During the production process, when it is necessary to perform forward foil discharge, the PLC control unit 23 will start the drive motor 20 according to the preset process parameters, discharge the foil according to the set speed and tension, and synchronize with the movement of the hot stamping roller to ensure the consistency of the hot stamping effect. When it is necessary to perform reverse foil discharge, the foil discharge direction can be switched, and the relevant parameters can be adjusted to achieve a smooth transition. The forward and reverse foil discharge systems of this hot stamping machine can be automatically integrated with the production process of the entire hot stamping machine. The foil placing system is designed to meet the needs of diversified hot stamping processes, realize accurate and stable foil placing operations in the forward and reverse directions, and improve the quality and production efficiency of hot stamping. In addition, the hot stamping machine can quickly and smoothly realize the conversion from forward foil placing to reverse foil placing, and the conversion process has little effect on the continuity of hot stamping. When placing the foil in the forward and reverse directions, the foil tension can be accurately controlled to keep the tension fluctuation within a very small range, so as to meet the strict requirements of fine hot stamping patterns on the amount of foil. During the use of the hot stamping machine, the foil is first placed on the foil placing shaft through the pressure wheel of the foil placing machine housing 22.

The forward and reverse foil-releasing systems of the hot stamping machine are automatically integrated with the production process of the entire hot stamping machine. In the production process, when the forward foil-releasing and hot stamping are required, The control system will start the foil release motor according to the preset process parameters, release the foil according to the set speed and tension, and synchronize with the movement of the hot stamping roller. The drive motor 20 in the hot stamping machine is responsible for the forward and reverse foil release drive respectively. The drive motor 20 is a high-precision servo motor with high response speed and precise speed control capabilities.
