Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically a pre-coating laminating machine for printing processing. Background Technology

[0002] In the process of printing, laminating machines are required. These machines are mainly divided into two types: instant laminating machines and pre-coated laminating machines.

[0003] Extensive searches revealed that CN204955705UU discloses a pre-coated laminating machine. By setting a first auxiliary conveying roller and a second auxiliary conveying roller, the tension of the pre-coated film and the material to be laminated can be adjusted to prevent wrinkles or loosening. By setting a first dust removal brush and a second dust removal brush, dust and impurities on the surface of the pre-coated film and the material to be laminated can be cleaned in a timely manner to avoid the generation of air bubbles and improve the quality of the laminated product.

[0004] In existing technology, when the device is in use, the outer circumferential surfaces of the second and third conveyor rollers are tangent to the outer circumferential surface of the first conveyor roller. In this case, even if different drive devices are configured for individual driving, there will still be some interference during the pre-coating operation. This causes the first, second, and third conveyor rollers to be obstructed when rotating and conveying the coating material and pre-coated film, thus affecting the normal coating process. Therefore, a pre-coating type laminating machine for printing processing is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-coated laminating machine for printing processing, which has the advantage of improving the conveying efficiency of laminating materials and pre-coated film, thereby improving the pre-coating efficiency. It solves the problem that the existing device is prone to conveying obstruction when conveying laminating materials and pre-coated film, which affects the processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-coated laminating machine for printing processing, comprising a base, a support frame fixedly installed at the rear end of the upper surface of the base, a baffle fixedly installed at the front end of the upper surface of the base, a coating film placement roller rotatably installed at the rear end of the top inner side of the support frame, a coating film body wound on the coating film placement roller, one end of the coating film body placed on the upper surface of the baffle, a groove is provided in the middle of the support frame and a pressure roller is movably installed thereon, the pressure roller is in contact with the upper surface of the coating film body but is not fixedly connected;

[0007] The upper surface of the baffle is provided with a reserved groove, and a transmission mechanism is provided at the reserved groove.

[0008] Preferably, a crossbar is fixedly installed at the top front end of the support frame, and a top plate is fixedly installed on the upper surface of the base inside the support frame. A placement plate is movably placed on the upper surface of the top plate, and a printing paperboard is placed on the upper surface of the placement plate opposite to the coating film body. The crossbar fixedly installed at the top front end of the support frame provides a stable support point for the cylinder and its connecting components. Simultaneously, a top plate is fixedly installed on the upper surface of the base inside the support frame, and a placement plate is movably placed on the upper surface of the top plate. This design allows the printing paperboard to be easily placed on the placement plate, forming a relative position with the coating film body, facilitating subsequent lamination operations. Furthermore, the design of the top plate and placement plate increases the flexibility and practicality of the equipment, allowing the position of the placement plate to be adjusted or different sizes of printing paperboard to be replaced as needed.

[0009] Preferably, a cylinder is fixedly mounted on the upper end face of the crossbar, and the bottom end of the cylinder passes through the crossbar and is fixedly mounted on a connecting plate. A mounting bracket is fixedly mounted on the rear end of the connecting plate. This design, with the cylinder fixedly mounted on the upper end face of the crossbar, allows the cylinder to move vertically downwards, driving the mounting bracket and the pressure roller below it to rise and fall via the connecting plate. This design not only simplifies the equipment structure but also improves the adjustment accuracy and stability of the pressure roller. Simultaneously, the use of a cylinder increases the automation level of the equipment and improves production efficiency.

[0010] Preferably, slide rails are fixedly installed on the inner sides of the support frames on both sides of the connecting plate, allowing the connecting plate to slide vertically along the slide rails on the inner sides of the support frames below the crossbar. This design ensures that the connecting plate maintains a stable and smooth movement trajectory during lifting and lowering, preventing shaking or jamming. Furthermore, the use of slide rails increases the durability and reliability of the equipment, extending its service life.

[0011] Preferably, the mounting frame is rotatably connected to the pressure roller via a connecting frame at its lower end. A fan is fixedly installed inside the mounting frame, and a resistance heater is fixedly installed at the bottom of the fan. This design, with the mounting frame rotatably connected to the pressure roller via a connecting frame at its lower end, allows the pressure roller to flexibly adapt to printing paperboard and coated film of different thicknesses, ensuring uniformity and quality in the lamination process. Simultaneously, the fan and resistance heater fixedly installed inside the mounting frame not only heat the material during lamination, promoting adhesive curing, but also accelerate heat dissipation through the fan's airflow, improving production efficiency. Furthermore, the combined use of the fan and resistance heater increases the equipment's versatility and flexibility.

[0012] Preferably, the transmission mechanism includes two drive rollers and two drive motors, with each drive motor mounted to drive the drive rollers. The printing paperboard and the coated film body, at the ends facing away from the coated film placement roller, pass through the opposite sides of the two drive rollers. This design allows the printing paperboard and the coated film body to be driven and conveyed forward simultaneously, ensuring the continuity and stability of the lamination operation. Furthermore, the drive motors, as a power source, offer advantages such as high efficiency, stability, and controllability, providing strong support for the normal operation of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a transmission mechanism installed in a pre-reserved groove on the upper surface of the baffle. This layout allows the transmission mechanism to directly act on the conveying path of the printed paperboard and the pre-coated film body. The transmission mechanism includes two drive rollers and two drive motors, which work together to stably and efficiently drive the coating material and pre-coated film forward. The pressure roller is movably installed in a groove in the middle of the support frame, contacting but not fixedly connected to the upper surface of the coating film body. This design allows the pressure roller to adjust the pressure on the coating material and pre-coated film according to actual needs, ensuring a tight fit while avoiding excessive pressure that could damage the material. The flexible adjustment of the pressure roller also means that it can adapt to coating materials and pre-coated films of different thicknesses and materials, thereby ensuring the stability and continuity of the conveying process. The coating film placement roller is rotatably installed on the inner top rear end of the support frame, providing stable support and a conveying path for the coating film body. This design allows the coating film body to remain flat and stable during conveying, avoiding conveying obstruction caused by material curling or wrinkling.

[0015] By optimizing the layout of the transmission mechanism and the adjustment method of the pressure rollers, the interference and friction on the coating material and pre-coated film during the conveying process are reduced. This design avoids the resistance caused by the relative movement between materials, thereby reducing the possibility of conveying obstruction. The coordinated work of the transmission mechanism and the pressure rollers enables the coating material and pre-coated film to maintain a stable speed and path during the conveying process. This design avoids problems such as material accumulation, curling or wrinkling caused by unstable conveying, thereby improving the efficiency and quality of pre-coating.

[0016] In summary, the pre-coated laminating machine for printing processing described above, through optimized design of the transmission mechanism layout, pressure roller adjustment method, and stable support of the coating film placement roller, effectively improves the conveying efficiency of laminating materials and pre-coated film, and effectively solves the problem of conveying obstruction that easily occurs in existing devices when conveying laminating materials and pre-coated film. These designs make the pre-coating process more efficient, stable, and quality-controllable, thereby meeting the printing processing industry's demand for high-quality, high-efficiency laminating equipment.

[0025] A reserved groove 51 is provided on the upper end face of the baffle 5, and a transmission mechanism 4 is provided at the reserved groove 51.

[0026] Specifically, a transmission mechanism 4 is installed in the reserved groove 51 on the upper surface of the baffle 5. This layout allows the transmission mechanism 4 to directly act on the conveying path of the printed paperboard and the pre-coated film body 3. The transmission mechanism 4 includes two transmission rollers 42 and two transmission motors 41, which work together to stably and efficiently drive the coating material and pre-coated film forward. The pressure roller 26 is movably installed in the groove in the middle of the support frame 2, contacting but not fixedly connected to the upper surface of the coating film body 3. This design allows the pressure roller 26 to adjust the pressure on the coating material and pre-coated film according to actual needs, ensuring that they fit tightly together while avoiding excessive pressure that could damage the material. The flexible adjustment of the pressure roller 26 also means that it can adapt to coating materials and pre-coated films of different thicknesses and materials, thereby ensuring the stability and continuity of the conveying process. The coating film placement roller 31 is rotatably installed on the inner top rear end of the support frame 2, providing stable support and a conveying path for the coating film body 3. This design allows the coating film body 3 to remain flat and stable during conveying, avoiding conveying obstruction caused by material curling or wrinkling.

[0027] By optimizing the layout of the transmission mechanism 4 and the adjustment method of the pressure roller 26, the interference and friction on the coating material and pre-coated film during the conveying process are reduced. This design avoids the resistance caused by the relative movement between materials, thereby reducing the possibility of conveying obstruction. The coordinated work of the transmission mechanism 4 and the pressure roller 26 enables the coating material and pre-coated film to maintain a stable speed and path during the conveying process. This design avoids problems such as material accumulation, curling or wrinkling caused by unstable conveying, thereby improving the efficiency and quality of pre-coating.

[0028] In summary, the pre-coated laminating machine for printing processing described above, through optimized layout of the transmission mechanism 4, adjustment method of the pressure roller 26, and stable support of the coating film placement roller 31, effectively improves the conveying efficiency of laminating materials and pre-coated film, and effectively solves the problem of conveying obstruction that easily occurs when conveying laminating materials and pre-coated film in existing technologies. These designs make the pre-coating process more efficient, stable, and quality-controllable, thereby meeting the printing processing industry's demand for high-quality, high-efficiency laminating equipment.

[0029] Example 2

[0030] To ensure better adhesion between the laminating material and the coated film during the lamination process, such as... Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a crossbar 22 is fixedly installed at the top front end of the support frame 2, and a top plate 11 is fixedly installed on the upper surface of the base 1 inside the support frame 2. A placement plate 12 is movably placed on the upper surface of the top plate 11, and a printing paperboard is placed on the side of the upper surface of the placement plate 12 opposite to the coating film body 3. The crossbar 22 fixedly installed at the top front end of the support frame 2 provides a stable support point for the cylinder 24 and its connecting components. Simultaneously, a top plate 11 is fixedly installed on the upper surface of the base 1 inside the support frame 2, and a placement plate 12 is movably placed on the upper surface of the top plate 11. This design allows the printing paperboard to be easily placed on the placement plate 12, forming a relative position with the coating film body 3, facilitating subsequent lamination operations. Furthermore, the design of the top plate 11 and the placement plate 12 increases the flexibility and practicality of the equipment, allowing the position of the placement plate 12 to be adjusted or different sizes of printing paperboard to be replaced as needed.

[0031] Furthermore, a cylinder 24 is fixedly mounted on the upper end of the crossbar 22. The bottom end of the cylinder 24 passes through the crossbar 22 and is fixedly mounted on a connecting plate 23. A mounting bracket 25 is fixedly mounted on the rear end of the connecting plate 23. The design of fixing the cylinder 24 to the upper end of the crossbar 22 allows the cylinder 24 to move vertically downwards, driving the mounting bracket 25 and the pressure roller 26 below it to rise and fall via the connecting plate 23. This design not only simplifies the equipment structure but also improves the adjustment accuracy and stability of the pressure roller 26. Simultaneously, the use of the cylinder 24 increases the automation level of the equipment and improves production efficiency.

[0032] Furthermore, slide rails 21 are fixedly installed on the inner sides of the support frames 2 on both sides of the connecting plate 23. The connecting plate 23 slides vertically on the inner side of the support frame 2 below the crossbar 22 via the slide rails 21. This design ensures that the connecting plate 23 maintains a stable and smooth movement trajectory during lifting and lowering, avoiding shaking or jamming. At the same time, the use of slide rails 21 increases the durability and reliability of the equipment, extending its service life.

[0033] Furthermore, the mounting frame 25 is rotatably connected to the pressure roller 26 via a connecting frame 27 below. A fan 251 is fixedly mounted inside the mounting frame 25, and a resistance heater 252 is fixedly mounted at the bottom of the fan 251. This design, with the mounting frame 25 rotatably connected to the pressure roller 26 via the connecting frame 27 below, allows the pressure roller 26 to flexibly adapt to printing paperboard and coated film body 3 of different thicknesses, ensuring uniformity and quality in the lamination operation. Simultaneously, the fan 251 and resistance heater 252 fixedly mounted inside the mounting frame 25 not only heat the material during the lamination process, promoting adhesive curing, but also accelerate heat dissipation through the blowing action of the fan 251, improving production efficiency. In addition, the combined use of the fan 251 and resistance heater 252 increases the equipment's versatility and flexibility.

[0034] Example 3

[0035] To ensure stable transport of the coating material after it adheres to the coating film during the lamination process, such as... Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the transmission mechanism 4 includes two transmission rollers 42 and two transmission motors 41. The two transmission motors 41 are respectively driven and installed with the transmission rollers 42. The printing paperboard and the coated film body 3, at the ends facing away from the coated film placement roller 31, pass through the opposite sides of the two transmission rollers 42. The transmission mechanism 4, designed to include two transmission rollers 42 and two transmission motors 41, with the two transmission motors 41 respectively driven and installed with the transmission rollers 42, allows the printing paperboard and the coated film body 3 to be driven and conveyed forward simultaneously, ensuring the continuity and stability of the lamination operation. Simultaneously, the transmission motors 41, as a power source, possess advantages such as high efficiency, stability, and controllability, providing a strong guarantee for the normal operation of the equipment.

[0036] In use, the coating film body 3 is wound around the coating film placement roller 31, ensuring that one of its extended ends is placed flat on the upper surface of the baffle 5. The printing paperboard to be coated is placed on the upper surface of the placement plate 12 and the baffle 5, ensuring that its relative position to the coating film body 3 is correct, and that both the coating film body 3 and the printing paperboard pass between the two drive rollers 42. The cylinder 24 is activated, which drives the pressure roller 26 on the mounting frame 25 and the connecting frame 27 to descend via the connecting plate 23, so that the pressure roller 26 contacts the coating film body 3 and the printing paperboard to perform a pressing operation. During this process, the extension and retraction of the cylinder 24 can be adjusted as needed to control the pressure of the pressure roller 26 on the material. The two drive rollers are then activated. Motor 41 starts the two drive rollers 42 to rotate, thereby conveying the printing paperboard and the coated film body 3. At the same time, the resistance heater 252 and the fan 251 are started to heat the coated film body 3 and the printing paperboard, promoting their adhesion. Driven by the drive motor 41, the coated film body 3 and the printing paperboard are continuously conveyed forward. After being pressed by the pressure roller 26 and heated by the resistance heater 252, the coating operation is completed. The coated product is output from the end of the two drive rollers 42 away from the pressure roller 26. After all materials have been coated, the drive motor 41, cylinder 24, resistance heater 252 and fan 251 are turned off, the equipment is cleaned, and it is ready for the next use.
