Description

Technical Field

[0001] This utility model relates to the technical field of guide rollers, and in particular to an adjustable guide roller mechanism that saves longitudinal space in a film coating equipment. Background Technology

[0002] In practical applications of laminating equipment, spatial layout is a key consideration. Traditional laminating equipment typically uses a fixed installation method for its guide roller mechanism, meaning the position of the guide rollers cannot be adjusted after the equipment is manufactured. This fixed guide roller mechanism occupies a large amount of space in the longitudinal direction, resulting in a relatively high overall height for the laminating equipment.

[0003] In certain specific locations, such as production environments with limited workshop height and compact space, or where integration with other equipment is required and there are strict restrictions on the overall height, traditional laminating equipment often fails to meet installation and usage requirements due to its excessive vertical space occupation, thus limiting the application scope of laminating equipment.

[0004] Furthermore, the guide rollers in traditional laminating equipment are in fixed positions, making it difficult to flexibly adjust the laminating tension for films of different materials and thicknesses, as well as for different production process requirements. This can lead to problems such as film loosening and wrinkling during the laminating process, affecting laminating quality and reducing production efficiency and product qualification rate. Utility Model Content

[0005] The purpose of this utility model is to disclose an adjustable guide roller mechanism that saves longitudinal space in a laminating equipment. The adjustable guide roller mechanism reduces the longitudinal space occupied by the laminating equipment to adapt to height-restricted locations, while realizing flexible and intelligent adjustment of laminating tension, thereby improving laminating quality and production efficiency.

[0006] To achieve the above objectives, this utility model discloses an adjustable guide roller mechanism that saves longitudinal space in a laminating equipment, comprising: an assembly including a first assembly plate and a second assembly plate, the first assembly plate being assembled with the side wall of the laminating equipment, and the second assembly plate being perpendicularly connected to the first assembly plate; a guide mechanism mounted on the second assembly plate, wherein the guide direction of the guide mechanism is perpendicular to the first assembly plate and parallel to the second assembly plate; a drive mechanism mounted on the second assembly plate; and a guide roller frame equipped with a passive roller, the guide roller frame being connected to the drive end of the drive mechanism, and the guide roller frame having a guide hole for the guide mechanism to pass through; the drive mechanism being used to drive the guide roller frame to perform linear reciprocating motion along the guide mechanism.

[0007] By adopting the above solution, the adjustment direction of the guide rollers is mainly horizontal. After assembling this adjustable guide roller mechanism, only the lateral space of the laminating equipment is increased, while the longitudinal space occupancy is significantly reduced. This effectively solves the problem of excessive longitudinal space occupation by traditional laminating equipment, making it unsuitable for installation in locations with limited height, and expands the application range of the laminating equipment. The guide roller frame can reciprocate linearly along the guiding mechanism under the drive mechanism, and the position of the guide rollers is adjustable in the horizontal direction. During the laminating process, according to the different materials and thicknesses of the film and the production process requirements, the position of the guide roller frame is precisely controlled by the drive mechanism, thereby adjusting the relative position between the guide rollers and the film to achieve flexible adjustment of the laminating tension. This adjustment method is more intelligent than the traditional fixed guide roller mechanism, effectively avoiding problems such as film loosening and wrinkling during the laminating process, improving laminating quality, increasing production efficiency, and improving product qualification rate.

[0008] Furthermore, the second assembly plate is provided with a hollowed-out portion, which divides the first assembly plate into two parts, and the area of ​​the hollowed-out portion is larger than the area covered by the passive roller when it moves.

[0009] By adopting the above solution, the hollowed-out section removes part of the material from the second assembly plate, reducing the overall mass of the adjustable guide roller mechanism. The segmented first assembly plate and the hollowed-out second assembly plate structurally create a certain elastic space, which can act as a buffer, reduce stress concentration, lower the risk of structural damage, and improve the stability and reliability of the entire mechanism. The hollowed-out area is larger than the area covered by the passive roller during movement, providing ample space for the linear reciprocating motion of the passive roller. The hollowed-out section allows operators to more easily observe the movement status and internal structure of the passive roller. During equipment operation, potential problems and malfunctions can be detected promptly, such as wear and loosening of the guide roller. The hollowed-out structure also facilitates air circulation, accelerating the dissipation of heat generated during operation. Especially during long-term continuous operation, good heat dissipation performance can prevent performance degradation or damage due to overheating, extending the equipment's service life and reducing downtime and maintenance costs caused by equipment failure.

[0010] Furthermore, a triangular rib is provided between the first assembly plate and the second assembly plate.

[0011] By adopting the above solution, the overall rigidity at the connection between the first and second assembly plates can be significantly enhanced. During the operation of the laminating equipment, the guide roller frame and its passive rollers are subjected to various forces, such as the tension of the laminating film and their own weight, which are transmitted to the assembly plates. The triangular ribs can effectively resist these external forces, preventing the assembly plates from bending or twisting excessively due to stress, and ensuring the structural integrity of the entire adjustable guide roller mechanism.

[0012] Furthermore, the guiding mechanism includes: a guide frame having a guide hole, the axial direction of which is perpendicular to the first assembly plate; and a guide rod passing through the guide hole of the guide frame and fixedly connected to the guide hole of the guide roller frame.

[0013] By adopting the above scheme, the axis of the guide perforation is perpendicular to the first assembly plate, providing a clear and fixed axis of motion for the guide rod. The guide rod, passing through the guide perforation, can only reciprocate along this axis, thus precisely limiting the direction of movement of the guide roller frame. This ensures accurate horizontal movement of the guide roller frame without deviation or wobbling, improving the precision of guide roller position adjustment during the lamination process and helping to guarantee lamination quality.

[0014] Furthermore, a sliding sleeve is provided between the guide rod and the guide frame, the sliding sleeve passing through the guide hole and being fixedly connected to the guide frame.

[0015] By adopting the above solution, the sliding sleeve, acting as an intermediate medium, bears most of the frictional force, avoiding direct wear between the guide rod and the guide frame. This significantly reduces the wear caused by long-term friction, extending the service life of both the guide rod and the guide frame. The sliding sleeve typically has a more uniform surface texture and structure, enabling the guide rod to experience more even force during movement. In contrast, the inner wall of the guide frame's guide perforation may have minor unevenness or machining errors, leading to localized stress concentration and accelerated wear during direct friction. The sliding sleeve effectively avoids this situation, further improving wear resistance. Because the sliding sleeve reduces friction and wear, the movement of the guide rod is more stable and reliable, better maintaining the predetermined movement trajectory.

[0016] Furthermore, one end of the sliding sleeve is provided with an assembly lip plate that abuts against the guide frame, and the assembly lip plate is provided with an assembly screw hole.

[0017] By adopting the above scheme, the assembly lip plate abuts against the guide frame, serving as a clear positioning reference during the installation of the sliding sleeve. Operators can quickly and accurately place the sliding sleeve in the predetermined position on the guide frame, ensuring that the axis of the sliding sleeve aligns with the axis of the guide hole. This avoids problems such as poor guide rod movement or jamming caused by installation deviations, improving installation efficiency and accuracy.

[0018] Furthermore, the outer diameter of the sliding sleeve is the same as the diameter of the guide hole, and the inner diameter of the sliding sleeve is the same as the diameter of the guide rod.

[0019] By adopting the above solution, this close fit eliminates radial clearance between the three components. During the guiding process, the guide rod can only move linearly along the precise axis defined by the sliding sleeve and the guide hole, without radial offset or wobbling. This ensures that the guide roller frame can move accurately in the predetermined direction, greatly improving the accuracy of guide roller position adjustment during the lamination process and helping to ensure the flatness and quality of the lamination.

[0020] Furthermore, there are two guide mechanisms, which are arranged in parallel and spaced apart, and the drive mechanism is located between the two guide mechanisms.

[0021] By adopting the above solution, during the operation of the laminating equipment, the guide roller frame needs to bear loads such as the tension of the laminating film and its own weight. Setting up two parallel and spaced-apart guide mechanisms can evenly distribute these loads across the two guide mechanisms, preventing premature wear or damage to a single guide mechanism due to excessive load. For example, when the laminating tension is high, the two guide mechanisms share the tension, with each guide mechanism bearing a relatively smaller force, thereby extending the service life of the guide mechanisms.

[0022] Furthermore, a drive bracket is provided between the drive mechanism and the second assembly plate. The drive bracket includes a vertically connected upright plate and a bottom plate. The bottom plate is assembled with the bottom of the second assembly plate. The upright plate extends outward from the bottom surface of the second assembly plate to the top surface of the second assembly plate. A drive assembly hole is provided on the upright plate, and the drive mechanism is assembled in the drive assembly hole.

[0023] By adopting the above scheme, a rigid structure resembling an "L" shape is formed. This structure provides stable support for the drive mechanism, enabling it to maintain a fixed position and posture during operation, reducing displacement and swaying caused by vibration or external forces, thereby ensuring the operational accuracy and stability of the entire device. When the drive mechanism operates, it generates certain forces and torques. The drive bracket can effectively distribute these forces and torques to the base plate and the second assembly plate. The base plate is assembled with the bottom of the second assembly plate, which can transfer forces over a larger area, avoiding local stress concentration and preventing the second assembly plate from deforming or being damaged due to excessive force, thus improving the load-bearing capacity and service life of the entire structure.

[0024] Furthermore, the upright plate has a first screw hole at the end corresponding to the second assembly plate, and the base plate has a second screw hole corresponding to the second assembly plate.

[0025] By adopting the above scheme, the first screw hole on the upright plate is used to connect with the second assembly plate at the end, and the second screw hole on the bottom plate connects with the bottom of the second assembly plate. Through these two screw holes at different locations, the drive bracket and the second assembly plate form a multi-point fixed connection. Compared with a single point or a few fixed points, multi-point fixing can significantly increase the stability of the connection, effectively preventing the drive bracket from loosening or shifting due to equipment vibration, external impact, or other factors during use, and ensuring that the drive mechanism is always in a stable working state.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional laminating equipment features a fixed guide roller mechanism, occupying significant space in the longitudinal direction and resulting in a relatively high overall equipment height. This adjustable guide roller mechanism, however, allows for adjustment primarily in the horizontal direction, increasing only the lateral space required after assembly while drastically reducing the longitudinal space occupied. This enables the laminating equipment to be installed and used in production environments with limited height and compact spaces, expanding its application range. The advantages of this adjustable guide roller mechanism are even more pronounced in locations requiring integration with other equipment and where overall height is strictly limited. It can better integrate with other equipment, achieving a compact and rational layout and improving the utilization rate of the production space. 2. During the lamination process, films of different materials and thicknesses require different tension levels. This adjustable guide roller mechanism's guide roller frame can reciprocate linearly along the guiding mechanism under the drive mechanism, and the position of the guide rollers is adjustable in the horizontal direction. Operators can precisely control the position of the guide roller frame through the drive mechanism according to the specific characteristics of the film, thereby adjusting the relative position between the guide rollers and the film to achieve flexible adjustment of the lamination tension. Different production processes also have different requirements for lamination tension. This adjustable guide roller mechanism can adjust the guide roller position in a timely manner according to changes in the production process, ensuring that the lamination process is always in an optimal tension state, meeting diverse production needs. 3. If the lamination tension is insufficient, the film is prone to loosening, resulting in uneven lamination. This adjustable guide roller mechanism precisely adjusts the tension, effectively preventing film loosening and ensuring the film adheres tightly and smoothly to the surface of the object being laminated, thus improving the appearance quality of the lamination. 4. Traditional fixed guide roller mechanisms often require complex disassembly and reinstallation operations when tension adjustment is needed, which is time-consuming and labor-intensive. In contrast, this adjustable guide roller mechanism only requires controlling the position of the guide roller frame through a drive mechanism to adjust the tension. This simple and quick operation greatly reduces adjustment time and improves production efficiency. Attached Figure Description

[0037] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0038] Please refer to Embodiment 1 of this utility model. Figures 1 to 3 As shown, this application embodiment provides an adjustable guide roller mechanism that saves longitudinal space of a laminating equipment, including an assembly 1, a guiding mechanism 2, a driving mechanism 3, and a guide roller frame 5. The entire mechanism is connected to the side wall of the laminating equipment through the assembly 1. The guiding mechanism 2 provides precise guidance for the movement of the guide roller frame 5. The driving mechanism 3 drives the guide roller frame 5 to perform linear reciprocating motion, thereby realizing the adjustment of the guide roller position to meet different laminating requirements.

[0039] Specifically, assembly 1 includes a first assembly plate 11 and a second assembly plate 12. The first assembly plate 11 is used to assemble with the side wall of the coating equipment, realizing the fixed connection between the entire adjustable guide roller mechanism and the coating equipment. The second assembly plate 12 is perpendicularly connected to the first assembly plate 11. Preferably, the second assembly plate 12 is provided with a hollow portion 121, which divides the first assembly plate 11 into two parts. The area of ​​the hollow portion 121 is larger than the area covered by the passive roller 52 when it moves. This design reduces the mass of the mechanism, provides elastic buffer space, reduces stress concentration, and facilitates observation of the movement status of the passive roller 52 and heat dissipation.

[0040] In some embodiments, a triangular rib 13 is provided between the first assembly plate 11 and the second assembly plate 12 to enhance the overall rigidity of the connection. The triangular rib 13 can effectively resist various external forces on the guide roller frame 5 and the passive roller 52 during the coating process, prevent the assembly plate from bending or twisting excessively, and ensure the integrity of the mechanism structure.

[0041] The guiding mechanism 2 includes a guide frame 21 and a guide rod 22. The guide frame 21 has a guide hole 211, the axis of which is perpendicular to the first mounting plate 11, providing a clear and fixed axis of motion for the guide rod 22. The guide rod 22 passes through the guide hole 211 of the guide frame 21 and is fixedly connected to the guide hole of the guide roller frame 5. In this way, the guide roller frame 5 can perform linear reciprocating motion along the axis of the guide hole 211 under the drive of the guide rod 22.

[0042] To reduce friction and wear between the guide rod 22 and the guide frame 21, in some embodiments, a sliding sleeve 23 is provided between the guide rod 22 and the guide frame 21. The sliding sleeve 23 passes through the guide hole 211 and is fixedly connected to the guide frame 21. One end of the sliding sleeve 23 is provided with a mounting lip plate 231 that abuts against the guide frame 21. The mounting lip plate 231 is provided with mounting screw holes for easy installation and positioning. At the same time, the outer diameter of the sliding sleeve 23 is the same as the diameter of the guide hole 211, and the inner diameter of the sliding sleeve 23 is the same as the diameter of the guide rod 22. This tight fit eliminates radial clearance and ensures the movement accuracy of the guide roller frame 5.

[0043] In this embodiment 1, two guide mechanisms 2 are provided, arranged parallel and spaced apart, with the drive mechanism 3 located between the two guide mechanisms 2. The drive mechanism 3 is mounted on the second assembly plate 12, providing power for the movement of the guide roller frame 5. A drive bracket 4 is provided between the drive mechanism 3 and the second assembly plate 12, the drive bracket 4 including a vertically connected upright plate 41 and a bottom plate 42. The bottom plate 42 is mounted to the bottom of the second assembly plate 12, and the upright plate 41 extends outward from the bottom surface of the second assembly plate 12 to the top surface of the second assembly plate 12. The upright plate 41 is provided with a drive assembly hole 411, into which the drive mechanism 3 is mounted. The end of the upright plate 41 corresponding to the second assembly plate 12 is provided with a first screw hole 412, and the bottom plate 42 is provided with a second screw hole 421 corresponding to the second assembly plate 12. These two screw holes enable multi-point fixed connection between the drive bracket 4 and the second assembly plate 12, increasing connection stability and ensuring stable operation of the drive mechanism 3. In other embodiments, the specific structure and assembly structure of the drive bracket 4 are not limited, as long as stable assembly can be achieved.

[0044] It should be noted that the drive mechanism 3 can be selected according to actual production needs, such as push rod motor, lead screw motor, cylinder or hydraulic cylinder, etc.

[0045] The guide roller frame 5 is equipped with a passive roller 52 for supporting and guiding the film coating. In this embodiment 1, two support plates 53 are vertically arranged on the guide roller frame 5, and the shaft 54 ​​is hinged between the two support plates 53 to ensure that the shaft 54 ​​can rotate freely on the support plates 53. Then, the passive roller 52 is sleeved on the shaft 54, so that the passive roller 52 can rotate with the rotation of the shaft 54, thus completing the installation of the passive roller 52. The guide roller frame 5 is connected to the drive end of the drive mechanism 3, and the guide roller frame 5 is provided with a guide hole for the guide mechanism 2 to pass through, so that the guide roller frame 5 can make linear reciprocating motion along the guide mechanism 2 under the drive of the drive mechanism 3, thereby adjusting the position of the guide roller in the horizontal direction.

[0046] Before the laminating equipment is put into operation, the adjustable guide roller mechanism is assembled to the side wall of the laminating equipment via the first assembly plate 11, according to the height limitations of the workshop space and the integration requirements with other equipment. During the lamination process, the operator starts the drive mechanism 3 according to the different materials and thicknesses of the film and the production process requirements. The drive mechanism 3 drives the guide roller frame 5 to move linearly back and forth along the guide mechanism 2. Since the guide mechanism 2 precisely restricts the movement direction of the guide roller frame 5, the guide roller frame 5 can accurately adjust its position in the horizontal direction, thereby adjusting the relative position between the guide roller and the film, and realizing flexible adjustment of the lamination tension. When the lamination tension is insufficient, the drive mechanism 3 drives the guide roller frame 5 to move in the appropriate direction to increase the film tension and prevent the film from slack. When it is necessary to adjust to adapt to different production processes, the drive mechanism 3 also precisely controls the position of the guide roller frame 5 to ensure that the lamination process is always in the optimal tension state.

[0047] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional laminating equipment features a fixed guide roller mechanism, occupying significant space in the longitudinal direction and resulting in a relatively high overall equipment height. This adjustable guide roller mechanism, however, allows for adjustment primarily in the horizontal direction, increasing only the lateral space required after assembly while drastically reducing the longitudinal space occupied. This enables the laminating equipment to be installed and used in production environments with limited height and compact spaces, expanding its application range. The advantages of this adjustable guide roller mechanism are even more pronounced in locations requiring integration with other equipment and where overall height is strictly limited. It can better integrate with other equipment, achieving a compact and rational layout and improving the utilization rate of the production space. 2. During the lamination process, films of different materials and thicknesses have different tension requirements. The guide roller frame 5 of this adjustable guide roller mechanism can reciprocate linearly along the guide mechanism 2 under the drive of the drive mechanism 3, and the position of the guide roller is adjustable in the horizontal direction. Operators can precisely control the position of the guide roller frame 5 through the drive mechanism 3 according to the specific characteristics of the film, thereby adjusting the relative position between the guide roller and the film to achieve flexible adjustment of the lamination tension. Different production processes also have different requirements for lamination tension. This adjustable guide roller mechanism can adjust the position of the guide roller in a timely manner according to changes in the production process, ensuring that the lamination process is always in the optimal tension state, meeting diverse production needs. 3. If the lamination tension is insufficient, the film is prone to loosening, resulting in uneven lamination. This adjustable guide roller mechanism precisely adjusts the tension, effectively preventing film loosening and ensuring the film adheres tightly and smoothly to the surface of the object being laminated, thus improving the appearance quality of the lamination. 4. Traditional fixed guide roller mechanisms often require complex disassembly and reinstallation operations when tension needs to be adjusted, which is time-consuming and labor-intensive. In contrast, this adjustable guide roller mechanism only requires the drive mechanism 3 to control the position of the guide roller frame 5 to adjust the tension, making the operation simple and quick, greatly reducing adjustment time and improving production efficiency.

[0048] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
