Description

Technical Field

[0001] This utility model relates to the field of label production technology, and in particular to a film coating device for the production of sterilization indicator labels. Background Technology

[0002] Sterilization indicator labels (such as chemical indicator cards, sterilization process challenge devices, etc.) are key products used in medical institutions, laboratories and pharmaceutical industries to monitor the effectiveness of sterilization. Their core structure usually includes a label substrate printed with chemical indicator ink and a transparent protective film covering the ink area to protect it from contamination and physical damage. During the production process, the protective film needs to be precisely and firmly laminated to the designated area of ​​the label substrate through a lamination process.

[0003] For example, CN213798747U discloses a laminating device for a label printing machine. This device uses an electric telescopic rod to drive an exhaust plate downward, which presses the laminated printed product down, thereby making the film and the printed product adhere more tightly and removing air bubbles between the film and the printed product, resulting in a better laminating effect.

[0004] However, when this venting structure is in use, the printing press is used for a long time and the laminated labels are constantly moving. This means that the electric telescopic rod needs to move back and forth quickly to remove air bubbles during the venting process. However, the speed of a conventional electric telescopic rod is not fast enough. As a result, some laminated label surfaces will not be able to remove air bubbles, thus reducing the effectiveness of the device.

[0005] Chinese patent discloses a label printing laminating device (authorization announcement number CN222407668U). This patented technology, through the setting of a protective structure, facilitates the elimination of air bubbles on the label surface lamination area by the continuous movement of the moving rod and defoaming plate. The rotation of the motor output shaft drives the drive wheel to rotate, which in turn drives the driven wheel to rotate slowly, thereby controlling the rotation speed of the laminating roller. At the same time, the rotation of the motor output shaft drives the half gear to rotate, which in turn drives the moving rod and defoaming plate to move up and down rapidly to defoam the label lamination area. This improves the effectiveness of the device and eliminates the need for an additional drive unit.

[0006] However, it has certain drawbacks: it lacks an effective guidance and positioning mechanism, and cannot prevent the labels from shifting during the transportation process due to various factors such as belt misalignment, uneven material tension, or equipment vibration, resulting in misalignment of the coating, blank edges, or wrinkles, thus leading to a decline in coating quality. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a laminating device for the production of sterilization indicator labels, which solves the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a film-coating device for the production of sterilization indicator labels, comprising: a label conveyor belt, wherein a set of limiting rollers is rotatably connected to both the left and right sides of the inner side of the label conveyor belt, and a film-coating mechanism is provided at the front edge of the upper surface of the label conveyor belt between the two sets of limiting rollers. A defoaming mechanism is provided on both the front and rear edges of the upper surface of the label conveyor belt, located to the left of the left limiting roller; an anti-deviation mechanism is provided on both the front and rear edges of the upper surface of the label conveyor belt, located to the right of the right limiting roller. The anti-deviation mechanism includes a second U-shaped frame. The upper surface of the second U-shaped frame has a sliding hole that extends through to the inner upper surface. Connecting blocks are fixed to both the front and rear sides of the upper surface of the second U-shaped frame at the sliding hole. A screw is rotatably connected between the two connecting blocks. Two connecting plates are symmetrically threaded between the two connecting blocks on the outside of the screw. A connecting hole extends through to the rear surface at the lower end of the front surface of the connecting plate. Anti-deviation roller 1 is rotatably connected to both the upper and lower surfaces of the inner side of the connecting hole. A set of anti-deviation roller 2 is provided on both the left and right sides of the connecting plate on the inner side of the second U-shaped frame.

[0009] As a further embodiment of this utility model, the second U-shaped frame is fixed to the front and rear edges of the upper surface of the label conveyor belt. The threads of the two connecting plates are opposite, and both connecting plates pass through the sliding hole. Each set of anti-deviation rollers includes two upper and two lower anti-deviation rollers, which are rotatably connected to the inner front and rear surfaces of the second U-shaped frame.

[0010] As a further embodiment of this utility model, the coating mechanism includes a support plate, a seat bearing is fixedly connected to the front surface of the support plate, a support roller is installed inside the seat bearing, and support discs are movably sleeved on both the front and rear sides of the support roller, with a support bolt threaded through the upper surface of the support disc.

[0011] As a further embodiment of this utility model, the support plate is fixed to the front edge of the upper surface of the label conveyor belt, the support roller moves through the support plate, and one end of the support bolt is attached to the support roller.

[0012] As a further embodiment of this utility model, the defoaming mechanism includes a U-shaped frame, a U-shaped plate is installed on the inner side of the U-shaped frame, and pressure rollers are rotatably connected to the front and rear surfaces of the inner side of the U-shaped plate.

[0014] This invention provides a lamination device for the production of sterilization indicator labels, which has the following advantages compared with the prior art: This design presents a laminating device for the production of sterilization indicator labels. Through its anti-deviation mechanism, it fundamentally avoids label misalignment caused by vibration, belt slippage, or uneven material tension during transport. The core of this device lies in the lateral positioning of the label from both sides using two precisely adjustable anti-deviation rollers, while vertical constraint is achieved through narrow channels formed by two sets of upper and lower anti-deviation rollers on the left and right sides. This three-dimensional positioning mechanism ensures that the label is stably transported along a preset path before entering the laminating station, laying a solid foundation for high-precision lamination. Combined with the laminating mechanism's convenient installation and quick roll-changing function for the protective film, and the synergistic effect of the positioning rollers and defoaming mechanism, the initially laminated label and film are stably guided. Then, the flexible pressure of the elastic rollers thoroughly eliminates air bubbles, significantly improving the flatness, adhesion, and alignment accuracy of the lamination. This enables continuous, efficient, and automated production after initial material feeding. The overall synergistic effect of the structure effectively guarantees the high quality and consistency of the sterilization indicator label products. Attached Figure Description

[0018] Please see Figure 1-5 This utility model provides a technical solution for a laminating device for the production of sterilization indicator labels: including a label conveyor belt 1; the belt surface of the label conveyor belt 1 is used to convey the indicator labels; A set of limiting rollers 2 are rotatably connected to the left and right sides of the inner side of the label conveyor belt 1; each set of limiting rollers 2 includes three rollers arranged from left to right. The limiting rollers 2 rotate on the front and rear frames of the label conveyor belt 1 through bearings and other standard parts, and are slightly higher than the upper surface of the conveyor belt. A film covering mechanism 3 is provided at the front edge of the upper surface of the label conveyor belt 1 between two sets of limiting rollers 2. The film covering mechanism 3 includes a support plate 4, which is fixed to the front edge of the upper surface of the label conveyor belt 1, that is, fixed to the upper surface of the front frame. A pedestal bearing 5 is fixedly attached to the front surface of the support plate 4, and a support roller 6 is installed inside the pedestal bearing 5. The pedestal bearing 5 includes a bearing housing and a bearing fixedly attached inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixedly attached to the bearing housing, the bearing housing is fixedly attached to the support plate 4, and the support roller 6 is fixedly attached to the inner bearing ring. Therefore, the pedestal bearing 5 and the support roller 6 are in a state of mutual rotation. The support roller 6 moves through the support plate 4. Support discs 7 are movably sleeved on both the front and rear sides of the support roller 6. Support bolts 8 are threaded through the upper surface of the support discs 7. One end of the support bolts 8 is attached to the support roller 6. The film roll is sleeved on the outside of the support roller 6. The support discs 7 fix the film roll to prevent it from moving axially. The support bolts 8 are used to lock the support discs 7 in any preset position of the support roller 6.

[0019] Please refer to this carefully. Figure 1 and Figure 4 As shown, a defoaming mechanism 9 is provided on the front and rear edges of the upper surface of the label conveyor belt 1, which is located on the left side of the left limiting roller 2. The defoaming mechanism 9 includes a U-shaped frame 10, which is fixed to the front and rear edges of the upper surface of the label conveyor belt 1, that is, fixed on the upper surface of the front and rear frames. A U-shaped plate 11 is installed on the inner side of the U-shaped frame 10. The front and rear surfaces of the inner side of the U-shaped plate 11 are rotatably connected to a pressure roller 12. The pressure roller 12 is used to squeeze the laminated label to eliminate air bubbles between the label and the film. Mounting rods 13 are fixedly connected to both the front and rear ends of the upper surface of the U-shaped plate 11. The mounting rods 13 movably pass through the U-shaped frame 10. A spring 14 is movably sleeved on the outside of the mounting rods 13. One end of the spring 14 is fixed to the upper surface of the U-shaped plate 11, and the other end of the spring 14 is fixed to the inner upper surface of the U-shaped frame 10. The spring 14 enables the pressure roller 12 to automatically adapt to the slight changes in the total thickness of the label and film, avoiding damage to the product due to excessive pressure or incomplete defoaming due to insufficient pressure, thus ensuring the consistency of the processing effect.

[0020] Please refer to this carefully. Figure 1 and Figure 5 As shown, an anti-deviation mechanism 15 is provided on the front and rear edges of the upper surface of the label conveyor belt 1, located on the right side of the right limiting roller 2. The anti-deviation mechanism 15 includes a U-shaped frame 16, which is fixed to the front and rear edges of the upper surface of the label conveyor belt 1. A sliding hole 17 is provided on the upper surface of the U-shaped frame 16, extending through to the inner upper surface. Connecting blocks 18 are fixed on both the front and rear sides of the upper surface of the U-shaped frame 16, and a screw 19 is rotatably connected between the two connecting blocks 18. The screw 19 is rotatably connected to the connecting blocks 18 through a bearing, and the screw 19 moves through the front connecting block 18. Two connecting plates 20 are symmetrically threaded between two connecting blocks 18 on the outside of the screw 19. The threads of the two connecting plates 20 are opposite, and both connecting plates 20 pass through the sliding hole 17. Since the threads of the two connecting plates 20 are opposite, rotating the screw 19 will cause the two connecting plates 20 to move synchronously relative to each other or in opposite directions. The lower end of the front surface of the connecting plate 20 is provided with a connecting hole 21 that extends to the rear surface. The upper and lower surfaces of the inner side of the connecting hole 21 are rotatably connected to the anti-deviation roller 22. The front and rear anti-deviation rollers 22 are used to limit the label and prevent the label from being directly conveyed on the belt surface and deviating. On the inner side of the U-shaped frame 216, on both the left and right sides of the connecting plate 20, there is a set of anti-deviation rollers 23. Each set of anti-deviation rollers 23 includes two rollers, one upper and one lower. The two anti-deviation rollers 23 are rotatably connected to the inner front and rear surfaces of the U-shaped frame 216. The upper and lower anti-deviation rollers 23 form a narrow channel through which the label passes, limiting the label in the vertical direction and preventing the label from tilting or shaking during transportation. Together with the anti-deviation roller 22, it achieves precise positioning and stable transportation of the label in three-dimensional space.

[0021] The working principle of this utility model is as follows: First, the operator rotates the screw 19 of the anti-deviation mechanism 15 according to the width of the label, driving two connecting plates 20 with opposite threads to move synchronously towards or away from each other along the sliding hole 17, thereby adjusting the distance between the two anti-deviation rollers 22 to a suitable position; then, the operator manually passes the indicator label to be coated through the narrow channel between the right set of anti-deviation rollers 23, then through the two anti-deviation rollers 22 whose distance has been adjusted, and then through the narrow channel between the left set of anti-deviation rollers 23, completing the initial positioning and anti-deviation of the label; after that, the label is guided to the surface of the label conveyor belt 1, so that it passes under the right set of limiting rollers 2, and the protective film led out from the support roller 6 of the coating mechanism 3 is manually pulled. The label is drawn down and initially bonded to the label. Then, the label, which has been initially coated, is manually guided to pass under a set of limiting rollers 2 on the left side to increase the lamination pressure and stabilize the conveying trajectory. Next, the composite material passes under the pressure roller 12 of the defoaming mechanism 9. The pressure roller 12 rolls the composite material under the elastic action of the spring 14 to completely eliminate air bubbles between the label and the film, ensuring a firm bond. Finally, the finished coated label with defoaming treatment is wound onto the external winding equipment. After the initial feeding is completed, the entire device can enter a continuous automated working state. The label conveyor belt 1 continuously conveys the labels, the lamination mechanism 3 continuously supplies protective film, and the defoaming mechanism 9 continuously rolls and defoams. Subsequent production processes do not require manual intervention.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
