Description

Technical Field

[0001] This utility model belongs to the technical field of rubber roller connection structure, and in particular relates to a rubber roller connection structure for EVA film production. Background Technology

[0002] Rubber rollers are mainly used in EVA film production for hot pressing, cooling, and shaping. During production, the rubber rollers come into contact with the EVA film surface, and through friction and pressure, maintain the film material at the specified thickness and structural shape on the production line. The rubber rollers must possess good heat resistance, wear resistance, and elasticity to ensure long-term stability and film quality during production.

[0003] A roller connection structure disclosed in the publication (publication number: CN216666273U) includes an inner roller and an outer roller, which are detachably connected by an expansion joint, which is an expansion ring. This application has the effect of enabling a detachable connection between the inner and outer rollers, allowing for replacement of the inner and outer rollers as needed, thereby reducing production costs.

[0004] In the aforementioned application, the interaction between the inner roller, the outer roller, and the expansion ring assembly makes it difficult to adjust the position of the roller during transmission or processing. This results in the roller being unable to flexibly adapt the spacing according to the material thickness, which can easily lead to unstable material transmission and insufficient processing accuracy. Therefore, we propose a rubber roller connection structure for EVA film production. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber roller connection structure for EVA film production. Through the design of components such as a base plate, support rod, roller, fixed plate, motor, threaded rod, and threaded sleeve, the problem of position adjustment in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a rubber roller connection structure for EVA film production, including a base plate, a support rod fixedly connected to the top of the base plate, the bottom of the support rod being located directly above the base plate, a roller being connected through the side of the support rod, and an adjustment device being provided on the top of the base plate;

[0008] The adjustment device includes a fixed plate whose side is fixedly connected to the side of a base plate. A motor is fixedly connected to the side of the fixed plate, and the motor is located directly above the base plate. A threaded rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. The circumferential surface of the threaded sleeve is fixedly connected to the side of a support rod. A sliding groove is provided on the top of the base plate, and a limit rod is slidably connected to the circumferential surface of the threaded sleeve. The main function of this device is to precisely adjust the height or position of the support rod through motor drive, so as to achieve fine control and adjustment. It may be used for precise positioning or adjustment functions in certain mechanical devices or automation systems.

[0009] Furthermore, four support rods are provided, symmetrically arranged along the vertical central axis of the base plate, and two rollers are provided. The four symmetrically arranged support rods increase the stability and balance of the entire structure, especially during load-bearing or adjustment, preventing skewing and instability. The two rollers provide support and guidance, ensuring smooth operation of the adjustment device and reducing friction, thereby guaranteeing the efficiency and stability of the entire system.

[0010] Furthermore, two slides are provided, symmetrically arranged along the vertical central axis of the base plate. The support rod is located directly above the slides. The two symmetrically arranged slides provide a stable and precise guide path, ensuring that the support rod can slide smoothly and accurately along the vertical central axis during adjustment. The cooperation between the slides and the support rod helps reduce friction, improves the accuracy and smoothness of the adjustment process, and enhances the stability of the entire structure.

[0011] Furthermore, a cleaning device is provided on the inner side of the chute. The cleaning device includes a fixed rod, the side of which is fixedly connected to the side of a support rod. A cleaning shovel is fixedly connected to the bottom of the fixed rod. A connecting rod is fixedly connected to the side of the support rod, and a force-bearing rod is fixedly connected to the bottom of the connecting rod. A brush is provided at the bottom of the force-bearing rod. Through the cooperation of the cleaning shovel and brush, the cleaning device can effectively remove debris and dust from the chute, ensuring that the support rod is not obstructed or experiences increased friction during sliding. This design extends the service life of the chute and support rod, improves the smoothness of the adjustment process, and ensures the efficient operation of the entire system.

[0012] Furthermore, the force-bearing rod and the cleaning shovel are both positioned directly above the chute. This placement effectively concentrates cleaning force on the inner wall of the chute, ensuring the cleaning shovel can smoothly remove dirt from within the chute through precise alignment and even force application. This combined arrangement helps prevent chute blockage, maintains smooth system operation, and improves the efficiency and stability of the cleaning process.

[0013] Furthermore, the number of brushes is set to several, and they are arranged in a linear array on the side of the force-bearing rod. The brushes are arranged in a linear array along the force-bearing rod, which can evenly distribute the applied force and avoid excessive local stress, thereby protecting the mechanical parts or surfaces from damage.

[0014] Furthermore, the fixing rod is located directly above the cleaning shovel, and the bottom of the cleaning shovel is slidably connected to the chute. This sliding connection gives the cleaning shovel flexible movement capabilities, enabling it to perform cleaning tasks accurately and evenly, while reducing friction and wear, and extending the service life of the equipment. The combination of these two elements makes the cleaning process more efficient and reliable, ensuring the long-term operation of the equipment.

[0015] This utility model has the following beneficial effects:

[0016] This invention achieves its purpose through the coordinated operation of components such as a base plate, support rods, rollers, a fixed plate, a motor, threaded rods, threaded sleeves, sliding grooves, and limiting rods. Four symmetrically arranged support rods are distributed along the central axis of the base plate, forming a balanced force-bearing frame. This not only disperses the pressure of the rollers on the base plate but also counteracts skew caused by unilateral force during adjustment, preventing structural swaying from affecting the flatness of the EVA film transport. Simultaneously, two symmetrical sliding grooves provide precise sliding trajectories for the support rods. Combined with the threaded transmission of the threaded sleeves and rods, the rotational motion of the motor is converted into stable linear motion of the support rods, achieving a highly efficient fusion of ease of operation and automated adaptation.

[0017] This invention achieves its purpose through the coordinated use of components such as a fixed rod, a cleaning shovel, a connecting rod, a force-bearing rod, and a brush. The cleaning shovel, through its sliding connection with the chute, can directly scrape away larger debris such as EVA film scraps and dust clumps accumulated in the chute, preventing hard particles from jamming the support rod. The brush then performs a thorough cleaning of the inner wall of the chute, removing residual fine dust. This dual cleaning ensures that no impurities remain in the chute. The cleaning device moves synchronously with the support rod. As the support rod slides, the cleaning shovel and brush remove dirt in real time, preventing impurities from rubbing against the inner wall of the chute or the bottom of the support rod for a long time, thus reducing component wear.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figures 1-4 This utility model is a rubber roller connection structure for EVA film production, including a base plate 1, a support rod 2 fixedly connected to the top of the base plate 1, the bottom of the support rod 2 located directly above the base plate 1, a roller 3 penetratingly connected to the side of the support rod 2, and an adjustment device 4 provided on the top of the base plate 1.

[0029] As shown in the figure, the adjusting device 4 includes a fixed plate 41, the side of which is fixedly connected to the side of the base plate 1. A motor 42 is fixedly connected to the side of the fixed plate 41, and the motor 42 is located directly above the base plate 1. A threaded rod 43 is fixedly connected to the output shaft of the motor 42. A threaded sleeve 44 is threadedly connected to the circumferential surface of the threaded rod 43. The circumferential surface of the threaded sleeve 44 is fixedly connected to the side of the support rod 2. A sliding groove 45 is provided on the top of the base plate 1. A limit rod 46 is slidably connected to the circumferential surface of the threaded sleeve 44. The main function of this device is to precisely adjust the height or position of the support rod 2 by driving the motor 42, so as to achieve fine control and adjustment. It may be used for precise positioning or adjustment functions in certain mechanical devices or automation systems.

[0030] As shown in the figure, there are four support rods 2, which are symmetrically arranged along the vertical central axis of the base plate 1. There are two rollers 3. The four symmetrically arranged support rods 2 increase the stability and balance of the entire structure, especially during load-bearing or adjustment, and can avoid skewing and instability. The two rollers 3 play a supporting and guiding role, so that the adjustment device 4 can operate smoothly and reduce friction, thereby ensuring the efficiency and stability of the entire system.

[0031] As shown in the figure, there are two slide grooves 45, symmetrically arranged along the vertical central axis of the base plate 1. The support rod 2 is located directly above the slide grooves 45. The two symmetrically arranged slide grooves 45 provide a stable and precise guide path, ensuring that the support rod 2 can slide smoothly and accurately along the vertical central axis during adjustment. The cooperation between the slide grooves 45 and the support rod 2 helps reduce friction, improve the accuracy and smoothness of the adjustment process, and enhance the stability of the entire structure.

[0032] As shown in the figure, a cleaning device 5 is provided on the inner side of the slide 45. The cleaning device 5 includes a fixed rod 51, the side of which is fixedly connected to the side of the support rod 2. A cleaning shovel 52 is fixedly connected to the bottom of the fixed rod 51. A connecting rod 53 is fixedly connected to the side of the support rod 2. A force-bearing rod 54 is fixedly connected to the bottom of the connecting rod 53. A brush 55 is provided at the bottom of the force-bearing rod 54. Through the cooperation of the cleaning shovel 52 and the brush 55, the cleaning device 5 can effectively remove debris and dust from the slide 45, ensuring that the support rod 2 is not obstructed or experiences increased friction during sliding. This design can extend the service life of the slide 45 and the support rod 2, improve the smoothness of the adjustment process, and ensure the efficient operation of the entire system.

[0033] As shown in the figure, the force-bearing rod 54 and the cleaning shovel 52 are both located directly above the chute 45. This arrangement effectively concentrates cleaning force on the inner wall of the chute 45. Precise alignment and even force application ensure that the cleaning shovel 52 can smoothly remove dirt from the chute 45. This coordinated operation helps prevent clogging of the chute 45, maintains smooth system operation, and improves the efficiency and stability of the cleaning process.

[0034] As shown in the figure, there are several brushes 55 arranged in a linear array on the side of the force-bearing rod 54. The brushes 55 are arranged in a linear array along the force-bearing rod 54, which can evenly distribute the applied force and avoid excessive local force, thereby protecting the mechanical parts or surfaces from damage.

[0035] As shown in the figure, the fixed rod 51 is located directly above the cleaning shovel 52, and the bottom of the cleaning shovel 52 is slidably connected to the slide groove 45. This sliding connection gives the cleaning shovel 52 flexible movement capabilities, enabling it to perform cleaning tasks accurately and evenly, while reducing friction and wear, and extending the service life of the equipment. The combination of these two elements makes the cleaning process more efficient and reliable, ensuring the long-term operation of the equipment.

[0036] A specific application of this embodiment is as follows: The base plate 1 supports the entire device, and the support rods 2 are symmetrically distributed, supporting the rollers 3 on both sides. These two rollers 3 are in direct contact with the EVA film. When the film passes through the middle, the rollers 3 will rotate, playing a role in conveying and flattening. When energized, they will drive the threaded rod 43 to rotate. The threaded rod 43 is fitted with a threaded sleeve 44. When the threaded rod 43 rotates, the threaded sleeve 44 will move back and forth. The threaded sleeve 44 is connected to the support rod 2, so when it moves, the support rod 2 will slide on the slide groove 45, thus adjusting the distance between the two rollers 3.

[0037] The cleaning shovel 52 and brush 55 are the core components, both fixed to the support rod 2. The cleaning shovel 52 is a small shovel with its bottom attached to the inner wall of the chute 45. When the support rod 2 slides, it first scrapes off large debris in the chute 45, such as fallen membrane fragments and dust clumps, to prevent these hard objects from getting stuck on the support rod 2. The brush 55 thoroughly sweeps away any remaining fine dust and small debris. The fixing rod 51 firmly fixes the cleaning shovel 52 to the support rod 2, ensuring that it does not wobble when shoveling. The cleaning shovel 52 and the chute 45 are slidably connected, which allows it to fit snugly against the chute wall without getting stuck too tightly.
