Description

Technical Field

[0001] This utility model belongs to the technical field of packaging paper coating curing device, and in particular relates to a double-sided synchronous curing device for medical packaging paper coating. Background Technology

[0002] Medical packaging paper, as a key material for the sterilization packaging of medical devices and medical supplies, plays an important role in maintaining the sterility of the products. To enhance its specific properties, such as heat-sealing properties, a coating is often applied to the surface of the packaging paper. After the coating is applied, it needs to be cured to ensure the stability of the coating performance. In the existing technology, a winding roller-type curing device is often used. The winding roller pulls the packaging paper and moves it through the curing area to achieve curing.

[0003] However, these curing devices are difficult to effectively adjust the tension of the packaging paper during use. When the tension of the packaging paper is too high, it is easy for the paper to break; while when the tension is too low, the packaging paper will wrinkle or shift during movement, which seriously affects the curing quality of the packaging paper and its subsequent performance. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided synchronous curing device for the coating of medical packaging paper. By incorporating a tension unit, specifically, when the tension of the packaging paper needs adjustment, a motor drives a rotating shaft to rotate a gear. A rack meshing with the gear slides, controlling the lifting and lowering of a U-shaped plate and tension roller to adjust the pressure on the packaging paper. Simultaneously, a guide rod guides and limits the movement of the U-shaped plate. This ensures stable tension of the packaging paper during transport, preventing loosening, wrinkling, or breakage, reducing slippage, adapting to different packaging paper materials, ensuring stability in the transport and curing processes, improving curing quality and production efficiency, and solving the problem of effectively adjusting the tension of the packaging paper during use.

[0037] Please see Figure 1-5As shown, this utility model is a double-sided synchronous curing device for the coating of medical packaging paper, including a base plate 1, a curing chamber 11 mounted on the top of the base plate 1, mounting plates 111 fixedly connected to the bottom and top walls of the curing chamber 11, ultraviolet curing lamps 112 fixedly connected to the sides of the two mounting plates 111 that are close to each other, a sealing door 113 mounted on the front of the curing chamber 11, a winding roller 12 mounted on the top of the base plate 1, packaging paper 13 passing through the curing chamber 11, one end of the packaging paper 13 being wound around the winding roller 12, and also including:

[0038] Tension section 2, installed on top of base plate 1, is used to adjust the tension of packaging paper 13 to ensure its stability and flatness during transmission, avoiding problems such as slackness, wrinkles, or breakage; and

[0039] Integration unit 3 is installed inside curing box 11. Integration unit 3 is used to squeeze the cured packaging paper 13 to eliminate the internal stress generated during curing, reduce the risk of the packaging paper 13 curling or coating cracking, and make the quality of the finished product more reliable.

[0040] The packaging paper 13 passes through the curing box 11 and passes between the ultraviolet curing lamps 112 between the two mounting plates 111, so that both sides of the packaging paper 13 are simultaneously cured by the ultraviolet curing lamps 112 on the two mounting plates 111.

[0041] The tension unit 2 includes a tension assembly 21, which is mounted on the top of the base plate 1. The tension assembly 21 is used to reduce slippage of the packaging paper 13 during transport, thereby ensuring the stability of the packaging paper 13 during transport; and

[0045] Elastic component 32 is installed on the outside of the curing chamber 11 and is used to make the extrusion component 31 elastic.

[0046] The extrusion assembly 31 and the elastic assembly 32 are provided in two sets. The two sets of extrusion assemblies 31 and elastic assemblies 32 are symmetrically installed on the top and bottom of the curing box 11, and the two sides of the packaging paper 13 are extruded by the cooperation of the two sets of extrusion assemblies 31 and elastic assemblies 32.

[0047] The tension assembly 21 includes a U-shaped frame 211 fixedly connected to the top of the base plate 1. A guide rod 212 passes through the top of the U-shaped frame 211. The guide rod 212 is slidably connected to the top of the U-shaped frame 211. A U-shaped plate 213 is fixedly connected to the bottom end of the guide rod 212. A tension roller 214 is rotatably connected to the inner wall of the U-shaped plate 213.

[0048] The outer surface of the tension roller 214 contacts the packaging paper 13 and is slidably connected to the packaging paper 13.

[0049] The adjustment assembly 22 includes a motor 221 installed on the front side of the U-shaped frame 211. The output shaft of the motor 221 is fixedly connected to a rotating shaft 222 via a coupling. The rear end of the rotating shaft 222 passes through the U-shaped frame 211 and is rotatably connected to the U-shaped frame 211. Two gears 223 are fixedly connected to the outer wall of the rotating shaft 222. Two racks 224 pass through the top of the U-shaped frame 211. The two racks 224 are slidably connected to the top of the U-shaped frame 211, and the two racks 224 mesh with the corresponding gears 223 respectively.

[0050] Two gears 223 are fixedly connected to the rotating shaft 222 by welding.

[0051] The extrusion assembly 31 includes two connecting rods 311 that pass through the top of the curing chamber 11. Both connecting rods 311 are slidably connected to the top of the curing chamber 11, and an extrusion plate 312 is fixedly connected to the bottom end of the two connecting rods 311.

[0052] The extrusion plate 312 is fixedly connected to the connecting rod 311 by bolts.

[0053] The elastic component 32 includes two sleeves 321 fixedly connected to the top of the curing box 11. The top ends of the two connecting rods 311 extend into the interior of the corresponding sleeves 321 and are slidably connected to the corresponding sleeves 321. Springs 322 are respectively sleeved on the outer walls of the two connecting rods 311.

[0054] One end of each of the two springs 322 is fixedly connected to the corresponding extrusion plate 312, and the other end is fixedly connected to the inner top wall of the curing box 11.

[0055] One specific application of this embodiment is: Ultraviolet curing lamp 112: Ultraviolet curing lamp 112 (UV curing lamp) is a device that uses ultraviolet (UV) irradiation to trigger a photochemical reaction, so that liquid materials such as coatings, inks, and adhesives can be quickly cured into solids. Its core working principle is based on the photosensitive reaction of photocurable materials.

[0056] When using this device, firstly, one end of the packaging paper 13 to be cured is passed through the curing chamber 11, then around the tension roller 214, and finally wound onto the take-up roller 12. The shaft end of the take-up roller 12 is connected to an external drive device, thereby driving the take-up roller 12 to rotate. The rotation of the take-up roller 12 drives the packaging paper 13 to be continuously conveyed. When passing the packaging paper 13 through the curing chamber 11, the sealing door 113 can be opened to facilitate the passage of the packaging paper 13 through the curing chamber 11. After the packaging paper 13 has passed through the curing chamber 11, the sealing door 113 is closed. The steadily conveyed packaging paper 13 passes through the curing chamber 11 and through the ultraviolet curing lamp 112 between the two mounting plates 111. The ultraviolet curing lamp 112 emits light after being powered on, synchronously irradiating both sides of the packaging paper 13, so that the coating of the packaging paper 13 is cured. This achieves simultaneous curing on both sides. When the tension of the packaging paper 13 needs to be adjusted, the motor 221 is started. The motor 221 drives the rotating shaft 222 to rotate, which in turn drives the gear 223 to rotate. The rack 224, which meshes with the gear 223, slides on the top of the U-shaped frame 211, thereby controlling the lifting and lowering of the U-shaped plate 213. The lifting and lowering of the U-shaped plate 213 drives the tension roller 214 to lift and lower, thereby adjusting the pressure of the tension roller 214 on the packaging paper 13 and realizing the adjustment of the tension of the packaging paper 13. This reduces the slippage phenomenon in the transmission of the packaging paper 13 and ensures the stable transmission of the packaging paper 13. At the same time, when the U-shaped plate 213 moves, it drives the guide rod 212 to slide. The guide rod 212 guides the movement of the U-shaped plate 213 and further limits the movement of the U-shaped plate 213, ensuring the stability of the U-shaped plate 213 during its movement.

[0057] After being cured by the ultraviolet curing lamp 112, the packaging paper 13 continues to move forward and enters the integration section 3. Two sets of extrusion components 31 and elastic components 32 are respectively provided. The components and working principles of the two sets of extrusion components 31 and elastic components 32 are completely identical. Four springs 322 push the corresponding extrusion plates 312 to apply pressure to both sides of the packaging paper 13. The sleeve 321 and connecting rod 311 in the elastic component 32 cooperate. When there are differences in the thickness or surface unevenness of the packaging paper 13, the extrusion plate 312, after contacting the packaging paper 13, will compress the spring 322 due to the change in resistance, causing the spring 322 to automatically extend and retract to adjust the extrusion plate 312. The position of the extrusion plate 312 is guided and limited by the connecting rod 311 and the sleeve 321. This adaptive adjustment ensures that the extrusion plate 312 always adheres to the surface of the packaging paper 13, maintains stable pressure, avoids crushing the paper due to excessive pressure, or poor extrusion effect due to insufficient pressure, effectively eliminates the internal stress of the packaging paper 13 during curing, improves the stability and reliability of the finished product quality, ensures stable extrusion by the extrusion plate 312, eliminates the internal stress generated during the curing of the packaging paper 13, reduces the risk of edge curling or coating cracking, and finally the winding roller 12 winds up the processed packaging paper 13, completing the entire double-sided synchronous curing process of the packaging paper coating.
