Description

Technical Field

[0001] The present invention belongs to the technical field of bronzing, and specifically relates to a bronzing processing device for cigarette box wrapping paper. Background Art

[0002] Cigarette box bronzing is a processing technology used to add gold or other metallic color decorations to the surface of cigarette boxes, which can enhance the beauty and texture of cigarette boxes; the bronzing paper is composed of electroaluminum paper and hot melt adhesive. During bronzing, the cigarette box print is placed on the workbench of the bronzing machine, and the bronzing paper is conveyed to the surface of the cigarette box to contact the bronzing plate through the paper feeding mechanism. Then, the bronzing machine applies pressure and heat to melt the hot melt adhesive layer of the bronzing paper, and transfers the metal foil to the surface of the cigarette box to form the required bronzing pattern or text.

[0003] During the bronzing process, although the bronzing plate is heated, if the temperature of the bronzing paper itself is too low, after the heat is transferred to the bronzing paper, it is not enough to make the hot melt adhesive reach the optimal melting state, resulting in a decrease in the adhesion between the metal foil and the surface of the cigarette box, and problems such as poor bronzing and gold peeling are likely to occur; for example, in a low-temperature environment in winter, if the bronzing paper and the cigarette box are not preheated and bronzing is directly carried out, the bronzing part of the bronzed cigarette box is likely to fall off during subsequent handling or packaging; moreover, the thickness of the hot melt adhesive in the bronzing paper is usually not completely uniform. During the production process, due to factors such as equipment accuracy, raw material characteristics, and production process, there may be a certain difference in the thickness of the hot melt adhesive. In the area where the thickness of the hot melt adhesive is relatively large, the bonding force is relatively strong, while in the area where the thickness of the hot melt adhesive is relatively thin, the bonding is not tight enough. During subsequent use or processing, the bronzing pattern is likely to partially fall off, affecting the bronzing effect. Summary of the Invention

Specific embodiments

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1:

[0034] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figures 1 - 10 shown, a bronzing processing device for cigarette box wrapping paper includes an equipment main body 1, a loading and unloading mechanism, a bronzing plate 11, a heating plate table 12, a pressure mechanism 13, a heating mechanism, a winding mechanism and a control system;

[0035] The above is the conventional structure of the bronzing equipment. The loading and unloading mechanism is used for loading and unloading cigarette box paper. The winding mechanism is used to move the bronzing paper, pull out the bronzing paper and move it under the bronzing plate 11, and wind and recycle it after the bronzing paper is bronzed; the bronzing plate 11 is installed on the heating plate table 12, and the heating mechanism heats the bronzing plate 11 through the heating plate table 12; during bronzing, the heated bronzing plate 11 descends through the pressure mechanism 13 to contact the bronzing paper, transfers heat to the bronzing paper, and at the same time, under the action of the pressure mechanism 13, presses materials such as metal foil on the bronzing paper onto the surface of the cigarette box paper to form the required bronzing pattern; the control system consists of an operation panel, a controller, etc., and is used to set and control various parameters of the bronzing machine, such as temperature, pressure, speed, etc. The operator inputs parameter instructions through the operation panel, and the controller adjusts the working states of each component according to these instructions to realize an automated bronzing process;

[0036] It further includes:

[0037] Storage box 14, the storage box 14 is installed at the bottom of the pressure mechanism 13, and sensors are evenly arranged inside the storage box 14; a winding shaft 15 is rotatably connected inside the storage box 14; a receiving shaft 16 is rotatably connected on one side of the winding shaft 15 inside the storage box 14, and the receiving shaft 16 is connected to a driving member 17 installed on the storage box 14. A rotating shaft 18 is evenly rotatably connected on one side of the inlet. A base paper 19 is wound around the receiving shaft 16 near the inlet. One end of the base paper 19 bypasses the rotating shaft 18 and is connected to a winding shaft. The base paper 19 arranged on the winding shaft 15 and the bronzing paper are wound on the surface together. The bronzing paper moves to below the bronzing plate 11 through an opening provided on one side of the storage box 14;

[0038] Slide rail 2, a slide rail 2 is provided on one side of the storage box 14, and a slide plate 21 is slidably connected to the slide rail 2. One side of the slide plate 21 is connected to an electric push rod 22 provided on the storage box 14. A spray pipe 23 and a suction groove 24 are respectively provided on the slide plate 21. The spray pipe 23 is located on one side of the suction groove 24. An air supply unit 25 is provided on the equipment main body 1. The air supply end and the suction end of the air supply unit 25 are respectively communicated with the spray pipe 23 and the suction groove 24, and the inside of the storage box 14 is communicated with the air supply unit 25;

[0039] The sensor is a conventional temperature and humidity sensor, which is used to monitor the temperature and humidity inside the storage box 14 and the bronzing paper in real time. The heater is a conventional electrical appliance for heating the box body. The slide rail 2 is a conventional rail for sliding and has the function of being resistant to high temperature; the air supply unit 25 is a combined device of a conventional air extraction pump, air supply pump, heater and humidifier, which has the functions of heating air and humidifying air while supplying air and extracting air; the air pipe connecting the air supply unit 25 and the spray pipe 23 is of a high-temperature resistant type, and the middle part of the air pipe connecting the spray pipe 23 and the air supply unit 25 contacts the heating plate table 12 or the heating mechanism, which is used to heat the air flowing in the spray pipe 23, so as to avoid the phenomenon that the temperature difference between the cleaning air sprayed from the spray pipe 23 to the bronzing plate 11 is too large, resulting in the thermal expansion and contraction of the bronzing plate 11 and causing damage to the graphics and texts on the bronzing plate 11; the bronzing paper is divided into two sides, the front side is made of materials such as metal foil, and the back side is hot melt adhesive;

[0040] Bronzing working steps:

[0041] Preparation stage: The operator installs the bronzing paper on the winding mechanism, adjusts the initial tension of the bronzing paper, places the cigarette case paper on the loading and unloading mechanism of the bronzing machine, and adjusts the position according to needs; at the same time, set parameters such as the temperature, pressure and speed of bronzing on the operation panel of the control system, and then start the heating mechanism to preheat the bronzing plate 11 to reach the set temperature;

[0042] Hot stamping stage: Driven by the control system, the winding mechanism feeds out the hot stamping paper smoothly at a set speed and passes it under the hot stamping plate 11. At this time, the pressure mechanism 13 starts to work under the command of the control system, applies a preset pressure to the heating plate table 12, drives the hot stamping plate 11 to descend and closely fit the surface of the cigarette box paper. At the same time, the heated hot stamping plate 11 transfers heat to the hot stamping paper, melts the hot melt adhesive layer of the hot stamping paper, and under the action of pressure, the metal foil is transferred from the hot stamping paper to the surface of the printing substrate to form a hot stamping pattern;

[0043] Rewinding stage: After one hot stamping, the winding mechanism works to wind up and collect the waste hot stamping paper after hot stamping to ensure that the hot stamping paper can continuously perform hot stamping operations while maintaining the stable tension of the hot stamping paper;

[0044] Circulation and end: After completing one hot stamping, the equipment automatically performs the next hot stamping operation according to the preset program, repeating the above steps until all printing substrates are hot stamped;

[0045] Specific working process: Before installing the roll-shaped hot stamping paper into the storage box 14, paste the backing paper 19 on the reverse side of the rolled hot stamping paper. The main function of the backing paper 19 is to serve as an attachment for the sticky paper, used to isolate the hot melt adhesive, so that the sticker can be easily peeled off from the backing paper 19. When the hot stamping paper enters the storage box 14 for preheating, the backing paper 19 can act as an isolation medium between the layers of the roll-shaped hot stamping paper, preventing the hot melt adhesive on the reverse side of the hot stamping paper from softening during the preheating process, resulting in adhesion between the layers of the hot stamping paper and tearing or other situations during the winding and moving process. Thus, while improving the preheating effect of the hot stamping paper, it ensures that the hot stamping paper can move completely, maintains a good state during the hot stamping process of the hot stamping paper, and further improves the hot stamping effect;

[0046] The hot stamping paper is installed on the unwind reel 15, or the hot stamping paper and the unwind reel 15 are disassembled and replaced together, that is, the worker can quickly replace it by opening the side door of the storage box 14, reducing the waiting time for replacing the hot stamping paper and improving the hot stamping efficiency. After the hot stamping paper is installed inside the storage box 14, the sensor detects the temperature and humidity of the hot stamping paper. The detection methods are as follows: for example, the infrared temperature sensor emits infrared light to the surface of the hot stamping paper, and calculates the temperature of the hot stamping paper surface according to the intensity and wavelength of the reflected light to complete the calculation of the temperature. The humidity sensor senses the water vapor content in the air around the hot stamping paper, converts the measured humidity signal into an electrical signal, and displays it through a data acquisition device or a display instrument to complete the calculation of the humidity. In this way, the temperature and humidity values of the hot stamping paper are obtained. If the temperature and humidity meet the hot stamping requirements, hot stamping starts; if not, it is stored in the storage box 14 for temperature and humidity adjustment;

[0047] The air supply unit 25 supplies air to and extracts air from the storage box 14, completes the replacement of the air in the storage box 14, and adjusts the temperature and humidity in the storage box 14. Affected by the environment in the storage box 14, the hot stamping paper gradually meets the temperature and humidity requirements for hot stamping work, avoiding a too large temperature difference between the hot stamping paper and the hot stamping plate 11. After the heat is transferred to the hot stamping paper, it is not sufficient to make the hot melt adhesive reach the best melting state, resulting in a decrease in the adhesion between the metal foil and the surface of the cigarette case; moreover, preheating the hot stamping paper in advance and shortening the temperature difference can also prevent the hot stamping paper from being damaged when it comes into contact with the high-temperature hot stamping plate 11, resulting in damage to the hot stamping paper. Therefore, by increasing the measures to protect the hot stamping paper, the hot stamping effect of the hot stamping paper is improved; furthermore, by keeping the hot stamping paper in a constant temperature state through the storage box 14 during continuous work, the hot stamping paper is prevented from being affected by the environment. For example, the temperature and humidity at the initial stage of the hot stamping paper work meet the hot stamping requirements, but after continuous work, the hot stamping paper is affected by the environment, and its temperature and humidity become higher or lower, resulting in a change in the temperature and humidity of the hot stamping paper during the mid-stage of work, causing the hot stamping effect to gradually deteriorate. Moreover, when problems occur with the hot stamping paper during the mid-stage of work, it is difficult for workers to detect them in time, resulting in the production of a large number of defective products and increasing production costs;

[0048] In addition, when installing the hot stamping paper, to ensure that the hot stamping paper can work continuously and reduce the time used for adjusting the temperature and humidity, when the worker starts working, two pieces of hot stamping paper are installed first, one for hot stamping and one for adjusting the temperature and humidity; then, during continuous hot stamping work, when the hot stamping paper for hot stamping is used up and removed, the hot stamping paper for adjusting the temperature and humidity is quickly replaced, and a new hot stamping paper is installed for adjusting the temperature and humidity, preparing for replacement and hot stamping;

[0049] During hot stamping, the driving member 17 drives the storage shaft 16 to rotate. While the storage shaft 16 winds up the base paper 19, it drives the winding shaft and the hot stamping paper to rotate by pulling the base paper 19, achieving the purpose of unwinding the hot stamping paper, and the tensile strength of the base paper 19 can meet the requirement of driving the winding shaft of the light material and the hot stamping paper to rotate; when the hot stamping paper is wound up, it passes between the axles 18 distributed up and down. When the hot stamping paper passes between the two axles 18, it is squeezed. At this time, the preheated and softened hot melt adhesive is located between the hot stamping paper and the base paper 19, and the hot melt adhesive is flattened by rolling with the axle 18, avoiding the phenomenon that the thickness of the hot melt adhesive is uneven and the hot stamping pattern falls off locally, affecting the hot stamping effect. Therefore, by flattening the hot melt adhesive, the hot stamping effect is improved; moreover, rolling with the axle 18 can also flatten the hot stamping paper, avoiding the creases caused by the bending of the hot stamping paper, which affects the hot stamping situation and improving the flatness of the hot stamping paper; furthermore, when the hot stamping paper is rolled, the hot melt adhesive is covered by the base paper 19, avoiding the hot melt adhesive sticking to other parts, resulting in the lack of hot melt adhesive amount on the hot stamping paper and affecting the hot stamping adhesion, and further improving the hot stamping effect; when the hot stamping paper bypasses the axle 18, the storage shaft 16 pulls and winds up the base paper 19, and the hot stamping paper is separated from the base paper 19, ensuring that the base paper 19 does not affect the work of the hot stamping paper;

[0050] After the hot stamping plate 11 works for a long time, impurities such as dust are likely to adhere to the hot stamping plate 11. The worker briefly stops the hot stamping work. At this time, the hot stamping paper is located between the cigarette case paper and the hot stamping plate 11 and moves away from each other. The worker starts the electric push rod 22, and the electric push rod 22 drives the sliding plate 21 to reciprocate between the hot stamping paper and the hot stamping plate 11 along the slide rail 2. When the slide rail 2 moves into contact with the heating plate table 12 and the hot stamping plate 11, the air supply unit 25 conveys high-temperature air to the spray pipe 23 to clean the heating plate table 12 and the hot stamping plate 11. While the impurities are blown away, the air supply unit 25 sucks away the blown air through the suction groove 24. Both the jetting and the air suction are carried out within the enclosure of the sliding plate 21. The impurities move within the closed space formed by the sliding plate 21 and the heating plate table 12, avoiding affecting the hot stamping paper when cleaning the hot stamping plate 11, thereby improving the hot stamping effect;

[0051] Moreover, the spray pipe 23 uses high-temperature air for cleaning, enabling the hot stamping plate 11 to be cleaned in a high-temperature state, reducing the cleaning waiting time and improving the cleaning efficiency. Also, the hot stamping plate 11 and the heating plate table 12 are cleaned together, avoiding impurities adhering to the heating plate table 12 from being transferred to the hot stamping paper or the cigarette case paper and affecting the hot stamping work.

[0052] Embodiment 2:

[0053] On the basis of Embodiment 1, one side of the base paper 19 is evenly provided with flexible plastic strips 26, and the surface of the plastic strips 26 away from the base paper 19 is evenly provided with connecting grooves 27, and the connecting grooves 27 are engaged with the surface of the rotating shaft 18; both ends of the rotating shaft 18 are rotatably connected with adjusting blocks 28, and one side of the adjusting blocks 28 away from the rotating shaft 18 is slidably connected with the inner wall of the storage box 14. A adjusting rod 29 is rotatably connected to the adjusting block 28 located below, and the adjusting block 28 located below is connected to the adjusting block 28 located above through the adjusting rod 29. The two rotating shafts 18 are driven by gear meshing, and the distance of the adjusting block driving the rotating shaft 18 to move up and down is within the range of 20 microns, which will not affect the meshing transmission of the two rotating shafts 18 through the gears. The worker can also change the transmission method according to the actual situation as long as the rotating directions of the two rotating shafts 18 are opposite; the middle parts of the upper and lower rotating shafts 18 contact the hot stamping paper and the base paper 19. The metal foil on the front of the hot stamping paper contacts the upper rotating shaft 18, and the hot melt adhesive on the back contacts the base paper 19 and contacts the lower rotating shaft 18 through the base paper 19, realizing the effect of the upper and lower two rotating shafts 18 rolling and hot stamping the hot stamping paper;

[0054] The inner wall of the storage box 14 is rotatably connected with a baffle 3, and the baffle 3 is connected with the unwinding shaft 15. The baffles 3 are distributed at both ends of the unwinding shaft 15. The baffle 3 is evenly provided with air holes 31, and the air holes 31 face the gaps between each layer of hot stamping paper after winding; the two baffles 3 are connected to the air supply unit 25, and the air holes 31 on one baffle 3 are communicated with the air supply end of the air supply unit 25, and the air holes 31 on the other baffle 3 are communicated with the air suction end of the air supply unit 25;

[0055] A rubber pad 32 is provided at the bottom of the plastic strip 26. When the hot stamping paper is wound, the bottom of the plastic strip 26 contacts the hot stamping paper through the rubber pad 32.

[0056] The plastic strip 26 is made of a conventional material for transmission. The rotating shaft 18 meshes with the connecting groove 27 on the plastic strip 26, so that the rotating shaft 18 drives the unwinding shaft 15, the hot stamping paper and the base paper 19 to rotate together by pulling the plastic strip 26. The rotating shaft 18 is installed on the inner wall of the storage box 14 through the adjusting blocks 28 at both ends. When the adjusting ring rises, the rotating shaft 18 rises. Workers can change the gap between the upper and lower rotating shafts 18 by moving the adjusting blocks 28.

[0057] Specific working process: The receiving shaft 16 winds the base paper 19 and the plastic strip 26. The plastic strip 26 provides a supporting force for the base paper 19 to prevent the base paper 19 from being pulled and torn. Moreover, through the cooperation of at least two plastic strips 26 on the base paper 19, the two side edges of the base paper 19 or the hot stamping paper move synchronously, avoiding skewing caused by pulling and preventing the situation of the hot stamping paper moving in a deviated direction, which affects the hot stamping work. Also, the hot stamping paper, the base paper 19 and the plastic strip 26 are in one layer. When the hot stamping paper has not been pulled out, there are multiple layers wound on the unwinding shaft 15. The plastic strip 26 acts as an isolation medium between each layer of hot stamping paper, making gaps appear between each layer of hot stamping paper, which helps the air for adjusting temperature and humidity in the storage box 14 to enter and contact the hot stamping paper, realizing an increase in the contact area between the hot stamping paper and the air, improving the conditioning efficiency, shortening the conditioning time, and thus improving the hot stamping efficiency. In addition, the plastic strip 26 on the first layer contacts the two side edges of the second layer of hot stamping paper and will not produce indentations on the hot stamping area in the middle of the hot stamping paper, ensuring that the plastic strip 26 does not affect the hot stamping work.

[0058] The thickness of the hot melt adhesive on the hot stamping paper will change according to the hot stamping requirements of the cigarette box paper. When the hot stamping paper is thicker, the worker rotates the adjusting rod 29 forward. The adjusting block 28 at the lower part remains stationary, and the adjusting block 28 at the upper part drives the rotating shaft 18 to rise, increasing the gap between the two rotating shafts 18 to meet the requirement of leveling the thicker type of hot stamping paper. When the hot stamping paper is thinner, the operation method is opposite to the above, reducing the gap between the two rotating shafts 18 to meet the requirement of leveling the thinner type of hot stamping paper, which is convenient for workers to adjust and improves the usage convenience. Also, since the two rotating shafts 18 are driven by conventional gears in mesh, the rotating shaft 18 at the upper part can rotate and roll synchronously with the moving speed of the hot stamping paper, avoiding a large friction between the rotating shaft 18 and the hot stamping paper and preventing the situation of the surface of the hot stamping paper being severely worn.

[0059] When installing the bronzing paper, workers can operate in various ways. For example, remove the housing in the installation area, take off the housing and the baffle 3, install the unwind reel 15 and the bronzing paper, and then reinstall the baffle 3 and the housing. After installation, the two baffles 3 cover the two side edges of the bronzing paper. The air supply unit 25 supplies air into one of the baffles 3 and extracts air from the other baffle 3. The air flows between the two baffles 3 through the air holes 31. The air for conditioning flows through the gaps formed by each layer of bronzing paper in the same direction, blowing away the impurities on the bronzing paper while shortening the moving distance of the impurities being blown away and preventing the impurities from floating in the storage box 14 and affecting the internal environment of the storage box 14.

[0060] Moreover, the bronzing paper is in close contact with the air just blown out for conditioning, avoiding the situation where the air contacts the bronzing paper after flowing in the storage box 14 for a period of time, which may cause changes in the temperature and humidity of the air and affect the conditioning effect of the bronzing paper. Also, the two baffles 3 cover the bronzing paper in the middle, making the gaps between each layer of the bronzing paper form a closed small space. Compared with the large space in the storage box 14, in the small space, the air circulation is relatively simple, and the generated air flow can be more easily evenly distributed throughout the small space, making the temperature and humidity reach uniformity in a short time. In addition, through the cooperation of the air holes 31 and the gaps between each layer of the bronzing paper, the whole bronzing paper is conditioned synchronously, which has a better effect than the conventional conditioning method from the outside to the inside.

[0061] By setting the rubber pad 32, the plastic strip 26 can be in flexible contact with the bronzing paper through the rubber pad 32, avoiding excessive indentation caused by excessive extrusion pressure and affecting the bronzing work.

[0062] Embodiment Three:

[0063] On the basis of Embodiment Two, a cleaning block 33 is slidably connected to the inner wall of the storage box 14, and the bottom of the cleaning block 33 is rotatably connected to a cleaning rod 34 through a torsion spring. A cleaning cotton is provided on the surface of the cleaning rod 34, and the cleaning cotton contacts the surface of the bronzing paper.

[0064] A pull rope 35 is wound around the end of the cleaning rod 34, and one end of the pull rope 35 is fixed to the inner wall of the storage box 14 at the top of the cleaning block 33.

[0065] Specific working process: The cleaning block 33 drives the cleaning rod 34 to descend. The cleaning rod 34 wipes the impurities on the surface of the hot stamping paper through the cleaning cotton; during the unrolling process of the hot stamping paper, the radius of the hot stamping paper roll gradually decreases. The cleaning block 33 drives the cleaning rod 34 to descend to keep in contact with the surface of the hot stamping paper, and further improves the cleanliness of the hot stamping paper surface through the functions of air blowing and wiping; moreover, the cleaning block 33 drives the cleaning rod 34 to press down, providing a resistance for the unrolling of the hot stamping paper, so that the hot stamping paper is in a taut state when it starts to unroll, reducing the excessive bending during the movement of the hot stamping paper and avoiding the appearance of creases caused by the excessive bending of the hot stamping paper; furthermore, with the support provided by the plastic strip 26, the excessive bending during the movement of the hot stamping paper is further reduced, thereby improving the hot stamping effect;

[0066] When the cleaning rod 34 descends, the pull rope 35 on the cleaning rod 34 is pulled out, so that the cleaning cotton rotates while descending. The cleaning cotton wipes the hot stamping paper in the reverse direction, that is, in the state where the cleaning cotton rotates counterclockwise and the hot stamping paper rotates clockwise. While increasing the friction generated by wiping, the impurities wiped off from the hot stamping paper are deflected to the side of the hot stamping paper away from the rotating shaft 18 to avoid the impurities remaining on the cleaning cotton; when the impurities fall, they are carried away by the air flow formed between the two baffles 3 and discharged from the storage box 14;

[0067] When replacing the hot stamping paper after it is used up, the worker lifts the cleaning block 33. After the pull rope 35 is no longer pulled, the cleaning rod 34 resets through the torsion spring.

[0068] Embodiment 4:

[0069] On the basis of Embodiment 3, a square tank 36 is provided on the inner wall of the storage box 14. The square tank 36 stores a demolding solution. A liquid dripping hole 37 is provided at the bottom of the square tank 36, and one side bottom of the square tank 36 contacts the rotating shaft 18 through a rubber sheet 38;

[0070] A zigzag air groove 4 is provided at the top of the sliding plate 21. The inside of the air groove 4 is connected to the air supply end and the suction end of the air supply unit 25. A sealing frame 41 is slidably connected in the air groove 4, and a sealing ring is provided at the top of the sealing frame 41;

[0071] A swing plate 42 is provided on one side of the top of the sliding plate 21 where the spray pipe 23 is located, and the swing plate 42 is connected to the sliding plate 21 through a torsion spring. A cleaning brush 43 is provided on one side of the swing plate 42, and a drying brush 44 is provided on the other side;

[0072] A camera assembly 5 is provided on one side of the sliding plate 21, and the camera assembly 5 faces the hot stamping plate 11;

[0073] The demolding solution is selected as silicone oil. For example, fluorosilicone oil, in addition to having the characteristics of general silicone oil, also has more excellent high and low temperature resistance, low friction coefficient and chemical stability. In a high-temperature hot stamping environment, it can better form a stable protective film, reduce impurity adhesion, and is convenient for cleaning at the same time. The cleaning brush 43 and the drying brush 44 are parts conventionally used for cleaning the hot stamping plate 11. The camera assembly 5 is a device conventionally used for visual inspection, and the camera assembly 5 is selected to have the function of high temperature resistance;

[0074] Specific working process: During hot stamping, the surface of the hot stamping paper away from the hot melt adhesive contacts the high-temperature hot stamping plate 11, resulting in a situation where the hot stamping paper is not easily separated from the hot stamping plate 11 or residual debris appears. Therefore, the square tank 36 drips the demolding solution onto the top of the rotating shaft 18 through the liquid dripping hole 37. The demolding solution flows between the rubber sheet 38 and the rotating shaft 18. The rubber sheet 38 spreads the demolding solution evenly on the rotating shaft 18, and the rotating shaft 18 then evenly rolls the demolding solution on the surface of the hot stamping paper. The silicone oil forms an isolation film between the hot stamping plate 11 and the hot stamping paper, preventing the hot melt adhesive from directly contacting the hot stamping plate 11, thereby effectively preventing the adhesion phenomenon between the hot stamping paper and the hot stamping plate 11;

[0075] Moreover, after hot stamping is completed, the hot stamping paper can be smoothly peeled off from the hot stamping plate 11, avoiding problems such as tearing of the hot stamping paper, incomplete patterns, and residual glue on the hot stamping plate 11 caused by adhesion. It helps to transfer the patterns and characters on the hot stamping paper clearly and completely to the printing substrate, reducing the occurrence of quality problems such as blurred patterns, missing parts, and bubbles, thereby improving the quality and effect of hot stamping. At the same time, the uniform distribution of silicone oil can also ensure the uniform transfer of hot stamping temperature and pressure, further enhancing the consistency and stability of hot stamping;

[0076] After the sliding plate 21 moves a fixed distance each time, the air supply unit 25 inflates the air groove 4, and the sealing frame 41 rises to contact the heating plate table 12, so that a sealed space is formed between the heating plate table 12 and the inside of the sliding plate 21, further ensuring that the cleaned impurities will not be blown away and improving the cleaning effect. After cleaning in this area, the air supply component pumps air out of the air groove 4, the sealing frame 41 descends back into the air groove 4, and the sliding plate 21 continues to move a fixed distance to repeat the above operation;

[0077] When impurities on the bronzing plate 11 are difficult to remove, steam is added to the air conveyed by the air supply unit 25 to the nozzle 23 to achieve steam cleaning and improve the cleaning effect. Then, when the slide plate 21 moves away from the storage box 14 for cleaning, the swing plate 42 is toggled so that the cleaning brush 43 contacts the heating plate table 12 and the bronzing plate 11. The combined effect of steam cleaning and scrubbing with the cleaning brush 43 further improves the cleaning effect. When the slide plate 21 returns and approaches the storage box 14, the slide plate 21 drives the swing plate 42 to move over the heating plate table 12. The swing plate 42 returns to the vertical state through the torsion spring. Then the slide plate 21 drives the swing plate 42 to contact the heating plate table 12 again, and the swing plate 42 is toggled in the reverse direction so that the drying brush 44 contacts the heating plate table 12 and the bronzing plate 11. Utilizing the high temperature of the drying brush 44 and the heating plate table 12, moisture is quickly removed, the cleaning efficiency is improved, the time for periodic cleaning is reduced, and the bronzing efficiency is increased. Moreover, through the treatment of the bronzing paper and the bronzing plate 11, the two act together to avoid problems that affect the bronzing effect, such as creases, insufficient adhesion, and excessive adhesion of impurities to the bronzing plate 11 during bronzing, thereby improving the practicality of the bronzing processing equipment.

[0078] While the slide plate 21 is cleaning the bronzing plate 11, it drives the camera assembly 5 to perform visual inspection on the bronzing plate 11. Workers can detect whether there are residues such as debris or hot melt adhesive in the pattern on the bronzing plate 11 through the camera assembly 5, which helps workers to understand the cleaning situation in detail, improve the cleaning effect, and thus improve the bronzing effect.
