Description

Technical Field

[0001] This utility model relates to the field of page-separation inkjet printing, and in particular to a UV page-separation machine's photocuring worktable. Background Technology

[0002] During the packaging coding process, stacks of plastic bags, packaging bags, paper boxes or cards of various specifications need to be automatically separated by a folding machine and individually conveyed to a conveyor belt for easy printing by a coding machine or laser machine to print production dates, batch numbers, anti-counterfeiting marks, patterns, etc.

[0003] After printing, the products need to be cured by UV light using a baking lamp. Therefore, UV collating machines are equipped with a UV curing cabinet for installing existing UV curing equipment. See [link / reference]. CN202123260818.1 A UV inkjet printing and pagination inspection integrated machine. Because the heating lamps inside the machine operate at high temperatures (around 160°C), prolonged heating can easily damage the conveyor belt. Therefore, the conveyor belt cannot be stopped during the heating lamp operation. Even so, the joints of the conveyor belt still exhibit warping and deformation during long-term heating. Even with reinforcement using stitching at the joints, the effect is not ideal.

[0004] Furthermore, if the packaging bag happens to be blocked by the heat lamps inside the machine during transport, the product may burn inside the machine due to the high temperature, potentially burning the conveyor belt or even causing a fire. Therefore, it is imperative to redesign the machine structure to address the impact of the heat lamps on the short lifespan of the conveyor belt and their influence on the safety of equipment operation. Utility Model Content

[0005] The purpose of this invention is to provide a UV collating machine with a light curing worktable that solves the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a UV curing workbench for a UV collating machine, comprising a conveying platform, a UV curing cover, and an arch support for mounting the UV curing equipment. A conveyor belt and a drive roller shaft are provided above the platform surface of the conveying platform. The conveyor belt is a circular conveyor belt, and there are multiple sets of circular conveyor belts, which are evenly spaced along the length of the drive roller shaft. The drive roller shaft has an annular positioning groove that matches the circular conveyor belt. A safety window is provided on the platform surface of the conveying platform, and the safety window is located below the UV curing equipment.

[0007] Preferably, the arch support is mounted on the frame of the conveyor platform and located inside the UV curing cover.

[0008] Preferably, the transmission roller shaft is mounted on the frame of the conveying platform, and a motor for driving the transmission roller shaft to rotate is provided at the bottom of the conveying platform.

[0009] Preferably, the circular conveyor belt is a polyurethane O-type connectable conveyor belt.

[0010] Preferably, the UV curing cover has a heat dissipation window on its side.

[0011] Preferably, the top of the UV curing cover is a cover plate structure, and the UV curing cover is rotatably connected to the cover plate via a hinge.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. This invention replaces the conventional conveyor belt with multiple sets of round conveyor belts. When products become stuck inside the UV curing chamber and are exposed to the heat lamp for an extended period, causing combustion, at most a few sets of round conveyor belts will burn out, preventing the entire conveyor belt from being destroyed. Furthermore, when a round conveyor belt burns out, the fire source will fall out through a safety window, preventing it from burning inside the UV curing chamber and thus preventing the fire from spreading and causing a fire. Moreover, each set of round conveyor belts is separate, unlike a single conveyor belt which may experience localized warping.

[0014] 2. This utility model has a safety window on the platform of the conveyor. In addition to facilitating the escape of fire sources, the safety window also provides good ventilation and heat dissipation. When the unit stops, the safety window can serve as a large open heat dissipation vent, which can quickly reduce the temperature inside the UV curing cover and extend the service life of the conveyor belt.

[0015] 3. The round belt conveyor can be a polyurethane O-type connectable conveyor belt. When the round belt conveyor is burned out and needs to be reinstalled, there is no need to disassemble the unit. Simply wrap the two ends of the round belt conveyor around the drive roller shaft, ignite and heat the joint, and then connect them. It is very convenient. Attached Figure Description

[0020] The present invention will be further described below.

[0021] Example: A UV collating machine's photocuring worktable, see [link / reference] Figures 1 to 3 The system includes a conveyor platform 1, a UV curing cover 5, and an arch support for mounting the UV curing equipment. A conveyor belt and a drive roller shaft 3 are mounted on the platform 11 of the conveyor platform 1. The conveyor belt is a circular conveyor belt 2, and there are multiple sets of circular conveyor belts 2, evenly spaced along the length of the drive roller shaft 3. The drive roller shaft 3 has annular positioning grooves 4 that match the circular conveyor belts 2. The annular positioning grooves 4 ensure that each set of circular conveyor belts 2 maintains the same spacing, which is better for transporting packaging bags. A safety window 6 is provided on the platform 11 of the conveyor platform 1, located below the UV curing equipment. This invention replaces the conventional conveyor belt with multiple sets of circular conveyor belts 2. When products become stuck inside the UV curing cover 5 and are exposed to the UV lamp for a long time, causing combustion, at most a few sets of circular conveyor belts 2 will burn out, and the entire conveyor belt will not be burned. Furthermore, when the circular conveyor belt 2 is burned out, the fire source will fall out through the safety window 6, preventing it from burning inside the UV curing cover 5 and thus preventing the fire from spreading and causing a fire. Also, each set of the circular conveyor belt 2 is separate, unlike a single conveyor belt which can have localized warping. The safety window 6, besides facilitating the escape of the fire source, also provides excellent ventilation and heat dissipation. When the unit stops, the safety window 6 acts as a large open heat dissipation vent, quickly reducing the temperature inside the UV curing cover 5 and extending the conveyor belt's lifespan. The circular conveyor belt 2 uses a polyurethane O-type connectable conveyor belt. When the circular conveyor belt 2 is burned out and needs to be reinstalled, there is no need to disassemble the unit. Simply wrap both ends of the circular conveyor belt 2 around the drive roller shaft 3, ignite and heat the joint, and then connect them – very convenient.

[0022] The arch support is mounted on the frame of the conveyor platform 1 and located inside the UV curing cover 5. The arch support is used to install the UV curing equipment, which is usually installed in the middle of the conveyor belt.

[0023] The transmission roller shaft 3 is mounted on the frame of the conveyor platform 1. The bottom of the conveyor platform 1 is equipped with a motor 7 that drives the transmission roller shaft 3 to rotate. The motor 7 drives the transmission roller shaft 3 to rotate, thereby driving the circular belt conveyor 2 to transport products.

[0024] The UV curing cover 5 is designed to prevent ultraviolet light leakage, which could cause light pollution and affect the health of workers, and to prevent ultraviolet light from shining on the print head of the printing section, causing the print head to harden.

[0025] The UV curing cover 5 has a heat dissipation window 51 on its side. Since the UV curing process generates a high temperature, the heat dissipation window 51 is designed to prevent the internal temperature of the UV curing cover 5 from becoming too high. A heat exchange fan can also be installed on the heat dissipation window 51 to further reduce the internal temperature of the UV curing cover 5. The effect is better when used in conjunction with the safety window 6.

[0026] The top of the UV curing cover 5 is a cover plate 52 structure, and the UV curing cover 5 is rotatably connected to the cover plate 52 via a hinge. The third-party UV curing equipment can be installed by opening the cover plate 52.

[0027] The above provides a detailed description of the UV curing worktable for a UV collating machine. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Modifications and improvements to this utility model are possible without exceeding the concept and scope defined in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
