Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil tape production and processing equipment, and in particular to a copolymer resin heat-sealing aluminum foil tape coating machine. Background Technology

[0002] In the production process of aluminum foil tape, a copolymer resin needs to be coated on the surface of the aluminum foil substrate to achieve the heat sealing function. This process relies on coating equipment.

[0003] However, existing aluminum foil tape coating machines often suffer from low automation, requiring manual assistance for tasks such as substrate feeding and coating pressure adjustment. This not only increases labor costs but also makes it difficult to ensure the continuity of operations, resulting in low production efficiency. Furthermore, the coating mechanism of existing coating machines lacks sufficient adjustment precision. When coating aluminum foil substrates of different thicknesses, it is difficult to accurately control the pressure applied by the pressure bar, leading to substrate misalignment and uneven coating, which affects the heat-sealing performance and product quality of the aluminum foil tape. In addition, some coating machines lack stable adjustment auxiliary structures. When adjusting the position of the movable table, component tilting can easily reduce coating precision, failing to meet the production requirements of high-quality aluminum foil tape. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low automation, poor coating accuracy, insufficient adjustment stability, difficulty in adapting to different specifications of substrates, and difficulty in balancing production efficiency and product quality in the existing technology. Therefore, a copolymer resin heat-sealing aluminum foil tape coating machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a copolymer resin heat-sealing aluminum foil tape coating machine, comprising a coating machine body, a take-up roller rotatably mounted at one end of the coating machine body, a release roller rotatably mounted at the other end of the coating machine body, and a coating mechanism fixedly mounted in the middle section of the coating machine body, the coating mechanism being located between the release roller and the take-up roller;

[0006] The coating mechanism includes a support platform and a movable platform. A protrusion is fixedly installed at the end of the movable platform, and a threaded rod is rotatably installed inside the protrusion. A limit plate is fixedly installed at the end of the support platform, and the end of the threaded rod is threadedly connected to the limit plate. The movable platform is located above the support platform, and a coating rod is rotatably installed on the inner side of the support platform. Pressure rods are rotatably installed on the inner side of the movable platform.

[0007] Preferably, a vertical rod is fixedly installed on the lower surface of the protrusion, and the vertical rod is inserted into the interior of the limiting piece.

[0008] Preferably, the limiting piece has a through hole inside, and the vertical rod is slidably connected to the limiting piece through the through hole.

[0009] Preferably, a tension spring is fixedly connected to the upper surface of the limiting piece, and one end of the tension spring is fixedly connected to the lower surface of the protrusion.

[0010] Preferably, the support platform has a groove inside, and the coating rod is located inside the groove.

[0011] Preferably, the vertical rod is located on both sides of the threaded rod.

[0012] Preferably, a gearbox is fixedly installed on one side of the coating machine body, and the output end of the gearbox is connected to the conveying roller inside the coating machine body.

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

[0014] 1. In this utility model, the release roller, coating mechanism, and winding roller on the main body of the coating machine form a collaborative working structure with the conveying roller driven by the gearbox, realizing the fully automated operation of the aluminum foil substrate from release, coating to winding. It eliminates the need for frequent manual intervention, greatly improving production efficiency. At the same time, it avoids errors caused by manual operation and effectively ensures the consistency of aluminum foil tape coating. It can not only accurately adjust the position and pressing force of the movable table and pressure bar to adapt to aluminum foil substrates of different thicknesses and types, but also prevent tilting of the movable table during adjustment.

[0015] 2. In this utility model, by setting a threaded adjustment structure of threaded rod and limiting plate in the coating mechanism, and with the sliding guide of vertical rod and through hole and the elastic assistance of tension spring, the parallelism of pressure rod and coating rod is ensured. Combined with the aggregation effect of groove on copolymer resin, the coating uniformity is further improved, the product quality of aluminum foil tape is significantly improved, and the versatility and operational stability of equipment are enhanced.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a copolymer resin heat-sealing aluminum foil tape coating machine, including a coating machine body 1. A take-up roller 3 is rotatably mounted at one end of the coating machine body 1, and a release roller 2 is rotatably mounted at the other end of the coating machine body 1. A coating mechanism 4 is fixedly mounted in the middle section of the coating machine body 1. The coating mechanism 4 is located between the release roller 2 and the take-up roller 3. The coating mechanism 4 includes a support platform 41 and a movable platform 42. A protrusion 45 is fixedly mounted at the end of the movable platform 42, and a screw is rotatably mounted inside the protrusion 45. The threaded rod 46 and the end of the support platform 41 are fixedly installed with a limiting piece 43. The end of the threaded rod 46 is threadedly connected to the limiting piece 43. The movable platform 42 is located above the support platform 41. The coating rod 47 is rotatably installed on the inner side of the support platform 41. The pressure rod 48 is rotatably installed on the inner side of the movable platform 42. The support platform 41 has a groove 49 inside. The coating rod 47 is located inside the groove 49. A gearbox 5 is fixedly installed on one side of the coating machine body 1. The output end of the gearbox 5 is connected to the conveying roller inside the coating machine body 1.

[0024] The specific setup and function of this embodiment are described in detail below. First, the aluminum foil substrate to be coated is released by the release roller 2, which is rotatably installed at the other end of the coating machine body 1. The aluminum foil substrate moves towards the middle section under the drive of the conveying roller inside the coating machine body 1. The power of the conveying roller is provided by the gearbox 5, which is fixedly installed on one side of the coating machine body 1. The output end of the gearbox 5 is connected to the conveying roller to drive its operation. When the aluminum foil substrate moves to the coating mechanism 4 located between the release roller 2 and the take-up roller 3, the coating rod rotatably installed inside the support platform 41 in the coating mechanism 4... 47. A copolymer resin coating operation is performed on the surface of the aluminum foil substrate. Simultaneously, the coating rod 47, rotatably mounted inside the support platform 41, is located inside a groove 49 formed within the support platform 41. The groove 49 is used to collect the resin. The rotation of the coating rod 47 applies the resin to the aluminum foil substrate. Meanwhile, the pressure rod 48 inside the movable platform 42 presses and limits the aluminum foil substrate during the coating process, ensuring a smooth coating. The position of the movable platform 42 can be adjusted by a threaded rod 46 rotatably mounted inside a protrusion 45 fixedly mounted at its end. The threaded rod 46 is aligned with the end of the support platform 41. The fixedly installed limiting piece 43 is threadedly connected. Rotating the threaded rod 46 can drive the movable table 42 to move up and down, thereby adjusting the pressing force of the pressure rod 48 on the aluminum foil substrate. The coated aluminum foil tape is finally wound up by the take-up roller 3, which is rotatably installed at one end of the coating machine body 1, to form the finished product. Through the cooperation of the release roller 2, coating mechanism 4, take-up roller 3 and the conveyor roller driven by the gearbox 5, the automated continuous operation of aluminum foil tape from substrate release, resin coating to finished product winding is realized, which effectively improves the coating efficiency. The coating mechanism 4 has a support table 41 in the coating mechanism 4. The coating rod 47 can stably complete the copolymer resin coating, and the pressure rod 48 of the movable table 42 can press and limit the aluminum foil substrate to prevent the substrate from shifting during coating, thus ensuring the uniformity of coating and product quality. At the same time, with the threaded connection structure between the threaded rod 46 in the protrusion 45 and the limiting piece 43, the position and pressing force of the movable table 42 and the pressure rod 48 can be flexibly adjusted to adapt to the coating needs of aluminum foil substrates of different thicknesses and types, enhancing the versatility and practicality of the equipment. This ensures the stability of the coating process and improves the convenience of production and the product qualification rate.

[0025] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a vertical rod 44 is fixedly installed on the lower surface of the protrusion 45. The vertical rod 44 is inserted into the interior of the limiting plate 43. A through hole 410 is provided inside the limiting plate 43. The vertical rod 44 is slidably connected to the limiting plate 43 through the through hole 410. A tension spring 411 is fixedly connected to the upper surface of the limiting plate 43. One end of the tension spring 411 is fixedly connected to the lower surface of the protrusion 45. The vertical rod 44 is located on both sides of the threaded rod 46.

[0026] The overall effect of this embodiment is that the vertical rod 44 fixed to the lower surface of the protrusion 45 is slidably connected to it through the through hole 410 inside the limiting plate 43. The vertical rod 44 is located on both sides of the threaded rod 46. When the threaded rod 46 is rotated to adjust the position of the movable table 42, the vertical rod 44 slides along the through hole 410, restricting the movable table 42 to move only in the vertical direction and preventing deviation. The tension spring 411 fixed between the upper surface of the limiting plate 43 and the lower surface of the protrusion 45 is always in a stretched state, providing elastic tension during the adjustment of the threaded rod 46 and helping to stabilize the movable table. Position 42 ensures uniform and continuous pressure from the pressure rod 48 on the aluminum foil substrate. The cooperation between the vertical rod 44 and the through hole 410 enhances the stability of the movable table 42 during adjustment, preventing tilting caused by uneven force on the threaded rod 46, ensuring the parallelism between the pressure rod 48 and the coating rod 47. The elastic force of the tension spring 411 makes the position adjustment of the movable table 42 smoother, reducing the impact of mechanical vibration on coating accuracy. At the same time, it buffers pressure fluctuations caused by slight changes in the thickness of the aluminum foil substrate, improves coating uniformity, and further optimizes the adjustment accuracy and working stability of the equipment.

[0027] The operating method and working principle of this device are as follows: The aluminum foil substrate to be coated is mounted on the release roller 2, which is rotatably mounted at the other end of the coating machine body 1. Ensure the aluminum foil substrate is fixed and stable. Simultaneously, check if the gearbox 5, fixedly mounted on one side of the coating machine body 1, is in normal working condition, ensuring it can provide power to the conveying roller inside the coating machine body 1. Depending on the thickness of the aluminum foil substrate to be coated, rotate the threaded rod 46, which is rotatably mounted inside the protrusion 45 fixedly mounted at the end of the movable table 42. Since the threaded rod 46 is threadedly connected to the limiting plate 43 fixedly mounted at the end of the support table 41, rotating the threaded rod 46 will cause the movable table 42 to move up and down. During this process, the vertical rod 44, fixedly mounted on the lower surface of the protrusion 45, will slide along the through hole 410 inside the limiting plate 43. The vertical rod 44 is located on both sides of the threaded rod 46 and is slidably connected to the limiting plate 43 through the through hole 410. At the same time, the upper surface of the limiting plate 43 and the lower surface of the protrusion 45... The fixedly connected tension spring 411 deforms as the movable table 42 moves until the movable table 42 is adjusted to a suitable position, so that the pressure rod 48, which is rotatably mounted inside the movable table 42, can form a suitable pressing limit on the aluminum foil substrate. The gearbox 5 is started, and the output end of the gearbox 5 drives the conveying roller inside the coating machine body 1 to rotate. The conveying roller drives the aluminum foil substrate on the release roller 2 to move towards the coating mechanism 4, which is fixedly mounted in the middle of the coating machine body 1. The coating mechanism 4 is located between the release roller 2 and the take-up roller 3. When the aluminum foil substrate moves to the coating mechanism 4, the coating rod 47, which is rotatably mounted inside the support table 41, performs copolymer resin coating on the surface of the aluminum foil substrate. At the same time, the pressure rod 48 inside the movable table 42 presses and limits the aluminum foil substrate during the coating process. The coated aluminum foil tape continues to move under the drive of the conveying roller, and is finally wound up by the take-up roller 3, which is rotatably mounted at one end of the coating machine body 1, to form the finished product.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
