Description
Technical Field
[0001] This utility model relates to a embossing and debossing device with die-cutting and pressing lines. Background Technology
[0002] Existing gravure printing equipment suffers from significant efficiency, cost, and quality control issues in actual operation: Firstly, the printing pattern and the indentation are located very close to each other, requiring the printing and die-cutting processes to be completely separate from the creasing process. Current technology cannot perform these processes simultaneously, necessitating multiple material transfers and repositioning adjustments between the two stages. This not only increases time consumption in intermediate steps but also risks affecting subsequent processing accuracy due to deviations during transfer, resulting in overall low efficiency. Secondly, the die-cutting blade, as a core consumable component, inevitably experiences edge wear after prolonged use, affecting die-cutting quality and requiring timely replacement. However, the current equipment integrates the die-cutting blade with the gravure printing plate in a fixed connection manner, making it impossible to disassemble it separately. Replacing the die-cutting plate requires replacing the entire plate, which significantly increases equipment maintenance costs and wastes resources on undamaged parts such as the plate itself. Thirdly, the die-cutting process is temperature-sensitive. Practice shows that die-cutting at around 35℃ significantly improves yield. However, existing equipment lacks effective temperature monitoring and intervention mechanisms, making it difficult to maintain this critical temperature condition. Therefore, a precise temperature detection and alarm system is urgently needed. This system must monitor the temperature of the die-cutting area in real time. When the temperature drops below 35℃, it should immediately issue an alarm signal and stop operation. Only after the operator adjusts the temperature to the standard range can the equipment be restarted to continue production, thus ensuring product quality stability. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a die-cutting and pressing device for embossing.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A die-cutting and relief printing device includes a gravure plate and a relief plate, the gravure plate and the relief plate cooperating with each other. The gravure plate includes a base plate and a plurality of molds for unfolding cigarette boxes, the plurality of molds for unfolding cigarette boxes being mounted on the base plate. A temperature detection alarm circuit is mounted on the side of the base plate. The plurality of molds for unfolding cigarette boxes include an elastic element, a die-cutting blade assembly, a first die-cutting plate, and a second die-cutting plate. The elastic element, the die-cutting blade assembly, the first die-cutting plate, and the second die-cutting plate are all detachably connected to the base plate. The die-cutting blade assembly is in close contact with the elastic element. The second die-cutting plate has relief lines and printed patterns, the printed patterns being located on both sides of the relief lines. The relief plate includes a base plate and a plurality of printing modules, the plurality of printing modules being mounted on the base plate. Each printing module includes a first printing plate and a second printing plate. The second printing plate has relief grooves and printed patterns, the printed patterns being located on both sides of the relief grooves. The relief lines cooperate with the relief grooves.
[0005] Preferably, the height of the die-cutting blade should be lower than the height of the elastic element.
[0006] Preferably, the second die-cutting plate further includes a plurality of mounting holes, through which the second die-cutting plate is mounted on the substrate.
[0007] Preferably, the die-cutting blade assembly includes a base and a blade. The base is mounted on a substrate and has a slot. The blade is detachably connected to the slot.
[0008] Preferably, the die-cutting blade assembly further includes several clamping posts, which are fixed on both sides of the top of the base and are used to fix the blades.
[0009] Preferably, the blade is made of magnetic material and can be magnetically attached and fixed in the slot to form a magnetic connection.
[0010] Preferably, the temperature detection alarm circuit includes a thermistor RT1, a sliding rheostat RV1, resistors R1, R2, and R3, transistors Q1 and Q2, an LED D1, a speaker BT, a switch S1, and a power supply A. One fixed terminal of the sliding rheostat RV1 is connected to the negative terminal of the power supply A, and another fixed terminal of the sliding rheostat RV1 is connected to its sliding terminal. The other fixed terminal of the sliding rheostat RV1 is connected to the base of transistor Q1 through resistor R2. The fixed terminal is connected to one end of resistor R3 via thermistor RT1. The emitter of transistor Q1 is connected to the emitter of transistor Q2, and the base of transistor Q1 is connected to the base of transistor Q2. The collector of transistor Q2 is connected to the negative terminal of power supply A. The collector of transistor Q1 is connected to the other end of resistor R3 via LED D1. One end of resistor R3 is connected to one end of speaker BT. The emitter of transistor Q1 is connected to the other end of speaker BT via resistor R3. One end of resistor R3 is connected to the positive terminal of power supply A via switch S1.
[0011] Preferably, power supply A is 9V.
[0012] The beneficial effects of this utility model are as follows: I. Improve production efficiency and reduce production costs This invention integrates several molds for the unfolded shape of cigarette boxes onto a gravure substrate, enabling the simultaneous processing of multiple cigarette boxes at once. This design significantly increases the output of cigarette boxes per unit time, reduces the time and labor costs of producing a single box, and effectively lowers the overall production cost from a mass production perspective.
[0013] Meanwhile, the innovative device enables the simultaneous execution of printing and die-cutting processes and the cross-pressing process. By precisely matching the cross-pressing lines and printed patterns on the second gravure die-cutting plate with the cross-pressing grooves and printed patterns on the second letterpress printing plate, the waiting time for process switching in traditional processes is eliminated, significantly shortening the production cycle and further improving overall work efficiency.
[0014] II. Enhance style adaptability to meet market demands The core components of this utility model adopt a detachable connection design. The elastic element, die-cutting blade assembly, first die-cutting plate, and second die-cutting plate can all be quickly disassembled and replaced with the gravure substrate, and the letterpress printing module can also be flexibly replaced.
[0015] Based on this structure, operators can easily switch between different cigarette box styles and printing patterns by quickly changing the printing plate and die-cutting plate without adjusting the entire device. This allows for rapid response to diverse market order demands, improving production flexibility and product competitiveness.
[0016] III. Ensure product quality and improve processing stability This invention features a temperature detection and alarm circuit on the side of the gravure substrate. When the temperature of the die-cutting area drops below 35°C, the thermistor in the circuit triggers a signal, which, via a transistor, controls an LED to illuminate as an alarm and a speaker to sound an alert. Simultaneously, the equipment stops operating. Production resumes only after the operator adjusts the temperature to the standard range, effectively preventing problems such as insufficient die-cutting precision and product defects caused by substandard temperatures, thus ensuring product quality stability.
[0017] Furthermore, the die-cutting blade assembly employs a dual fixing structure of "magnetic adsorption + clamping post fixation." The blade is made of magnetic material, allowing it to be directly adsorbed and fixed within the base slot, forming a preliminary stable connection. The clamping posts on both sides of the top of the base further limit and fix the blade. This design completely avoids blade vibration and displacement during die-cutting, ensuring a smooth die-cut edge, meeting accuracy standards, and significantly improving the die-cutting processing effect.

Detailed Implementation
[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings: like Figures 1 to 5As shown, a die-cutting and embossing device includes a gravure plate and an embossing plate, which cooperate with each other. The gravure plate includes a base plate 11 and several molds for unfolding cigarette boxes. The molds for unfolding cigarette boxes are mounted on the base plate 11. A temperature detection alarm circuit 111 is mounted on the side of the base plate 11. The molds for unfolding cigarette boxes include an elastic element 12, a die-cutting blade assembly 13, a first die-cutting plate 14, and a second die-cutting plate 15. The elastic element 12, the die-cutting blade assembly 13, the first die-cutting plate 14, and the second die-cutting plate 15 are all detachable from the base plate 11. The die-cutting blade assembly 13 is tightly attached to the elastic element 12. The second die-cutting plate 15 is provided with a pressing line 151 and a printed pattern 152. The printed pattern 152 is located on both sides of the pressing line 151. The relief plate includes a base plate 21 and several printing modules. The several printing modules are installed on the base plate 21. The printing module includes a first printing plate 22 and a second printing plate 23. The second printing plate 23 is provided with a pressing groove 24 and a printed pattern 152. The printed pattern 152 is located on both sides of the pressing groove 24. The pressing line 151 cooperates with the pressing groove 24.
[0020] like Figures 1 to 5 As shown, the height of the die-cutting blade is lower than the height of the elastic member 12. The second die-cutting plate 15 also includes several mounting holes 153, and the second die-cutting plate 15 is mounted on the substrate 11 through the several mounting holes 153.
[0021] like Figure 2 As shown, the die-cutting blade assembly 13 includes a base 131 and a blade 132. The base 131 is mounted on the base plate 11 and has a slot 1311. The blade 132 is detachably connected to the slot 1311.
[0022] like Figure 2 As shown, the die-cutting blade assembly 13 also includes several clamping posts, which are fixed to both sides of the top end of the base 131. The clamping posts are used to fix the blade 132. The blade 132 is made of magnetic material and can be magnetically attached and fixed in the slot 1311 to form a magnetic connection.
[0023] like Figure 6As shown, the temperature detection alarm circuit 111 includes a thermistor RT1, a sliding rheostat RV1, resistors R1, R2, and R3, transistors Q1 and Q2, an LED D1, a speaker BT, a switch S1, and a power supply A. One fixed terminal of the sliding rheostat RV1 is connected to the negative terminal of the power supply A, and another fixed terminal of the sliding rheostat RV1 is connected to its sliding terminal. The other fixed terminal of the sliding rheostat RV1 is connected to the base of transistor Q1 through resistor R2. Thermistor RT1 is connected to one end of resistor R3. The emitter of transistor Q1 is connected to the emitter of transistor Q2, and the base of transistor Q1 is connected to the base of transistor Q2. The collector of transistor Q2 is connected to the negative terminal of power supply A. The collector of transistor Q1 is connected to the other end of resistor R3 through LED D1. One end of resistor R3 is connected to one end of speaker BT. The emitter of transistor Q1 is connected to the other end of speaker BT through resistor R1. One end of resistor R3 is connected to the positive terminal of power supply A through switch S1. Power supply A is 9V.
[0024] Working principle: This device uses precise coordination between gravure and letterpress printing to simultaneously complete the printing, die-cutting, and pressing processes of cigarette boxes. The specific process is as follows: Process Start-up and Temperature Monitoring: After the device is turned on, the temperature detection and alarm circuit on the side of the substrate works synchronously. Thermistor RT1 monitors the temperature of the die-cutting area in real time. When the temperature is below 35℃, the current signal in the circuit changes, triggering transistors Q1 and Q2 to conduct, LED D1 to light up, speaker BT to sound an alarm, and the equipment to stop. Once the temperature is adjusted to the standard range, the circuit resets, and the equipment can be restarted.
[0025] Printing and folding are performed simultaneously: the second die-cutting plate of the gravure plate has folding lines and printed patterns, while the second printing plate of the letterpress plate has corresponding folding grooves and the same printed patterns. When the gravure and letterpress plates are closed, their printed patterns work together to complete the printing on the cigarette box surface, and the folding lines and grooves precisely interlock, simultaneously pressing out the folding lines on the cigarette box paper.
[0026] Die-cutting and structural protection: The magnetic blades of the die-cutting blade assembly are securely mounted on the base via slots and clamping posts, allowing for quick replacement of the die-cutting blade assembly. During the pressure application process between the gravure and relief printing plates, the elastic element provides cushioning. The die-cutting blade assembly die-cuts the cigarette box paper under pressure. Because the height of the die-cutting blade is lower than that of the elastic element, over-cutting damage to the equipment is avoided, while ensuring a clean cut. The rebound force of the elastic element causes the gravure and relief printing plates to separate.
[0027] Style switching operation: When it is necessary to change the style of cigarette box, the second die-cutting plate can be removed through the mounting holes on the base plate. At the same time, the die-cutting blade assembly of the gravure plate and the printing module of the relief plate can be removed and replaced with the new parts of the corresponding style, so that the production of the new style of cigarette box can be started quickly.
[0028] The intaglio substrate integrates molds for several unfolded cigarette boxes, allowing for the processing of multiple cigarette boxes at once. This significantly increases output per unit time and directly reduces labor and time costs for producing a single box.
[0029] The printing, die-cutting, and cross-pressing processes are completed simultaneously, eliminating the waiting time for process switching in traditional processes, shortening the production cycle, and significantly improving overall work efficiency.
[0030] The die-cutting blade assembly, the second die-cutting plate, and the letterpress printing module all feature a detachable design, allowing for quick replacement. Different cigarette box styles can be switched without overall equipment adjustments, enabling rapid response to diverse market order demands.
[0031] The temperature detection alarm circuit monitors a 35℃ threshold and automatically alarms and stops the machine when the temperature drops below this level, thus avoiding defects such as rough edges in die-cutting and blurry printing caused by substandard temperature and ensuring stable product quality.
[0032] The die-cutting blade adopts a dual structure of "magnetic adsorption + clamping column fixation" to completely eliminate blade vibration during the die-cutting process. Combined with the buffering effect of the elastic element, the cutting accuracy and the clarity of the cross lines are higher.
[0033] The second die-cutting plate can be quickly installed and removed through the mounting holes, and the magnetic blade can be removed from the slot for replacement without complicated tools, reducing the maintenance difficulty and workload for operators.
[0034] The temperature alarm circuit uses a 9V low-voltage power supply, has a simple structure, high safety, convenient component replacement during subsequent maintenance, and low maintenance cost.
[0035] It should be noted that the above examples are only one specific embodiment of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. In short, all variations that can be directly derived or conceived by those skilled in the art from the content disclosed in this utility model should be considered within the protection scope of this utility model.
