Description

Technical Field

[0001] This utility model relates to the technical field of guide rollers, and in particular to an adjustable passive roller unit. Background Technology

[0002] In the field of lamination equipment, the stability and efficiency of the lamination process play a crucial role in product quality and production efficiency. During the lamination process, the tension of the film directly affects the lamination effect. If the film tension is uneven or inappropriate, defects such as wrinkles and bubbles can easily occur, affecting the appearance and quality of the product. Therefore, accurately and flexibly adjusting the film tension is one of the key issues that lamination equipment needs to address.

[0003] In traditional laminating equipment, the design of the guide roller mechanism often has many limitations. On the one hand, many guide roller mechanisms have a fixed structure, and the position of the passive roller cannot be flexibly adjusted according to actual laminating needs. When faced with films of different specifications and materials or when laminating process requirements change, it is difficult to effectively adjust the film tension, resulting in unstable laminating quality and an inability to meet diverse production needs.

[0004] On the other hand, while some existing adjustable guide roller mechanisms can adjust the position of the passive roller, their overall structural design is complex and occupies a large space. This not only increases the overall size of the laminating equipment, making it difficult to arrange within a limited production space, but also makes transportation and storage extremely inconvenient, requiring a large amount of storage space and increasing transportation and storage costs. Furthermore, the complex structure leads to cumbersome assembly and disassembly processes, requiring specialized technicians and consuming significant time and manpower, hindering rapid deployment and maintenance. Utility Model Content

[0005] The purpose of this invention is to disclose an adjustable passive roller unit that effectively solves the technical problems of traditional guide roller mechanisms in terms of film tension adjustment, assembly space occupation, transportation and storage, and assembly and disassembly efficiency.

[0006] To achieve the above objectives, this utility model discloses an adjustable passive roller unit, comprising: an assembly plate, the assembly plate including a first assembly surface and a second assembly surface opposite to the first assembly surface, the first assembly surface being used for assembly to the side wall of a coating equipment; a guiding mechanism, one end of the guiding mechanism being assembled to one side of the second assembly surface of the assembly plate, and the other end being assembled to a fixing plate; a driving mechanism, the driving mechanism being assembled to the fixing plate; a guide roller frame, the guide roller frame being equipped with a passive roller, the guide roller frame being connected to the driving end of the driving mechanism, and the guide roller frame being provided with a guide hole for the guiding mechanism to pass through; the driving mechanism being used to drive the guide roller frame to perform linear reciprocating motion along the guiding mechanism.

[0007] By adopting the above scheme, the drive mechanism drives the guide roller frame to reciprocate linearly along the guide mechanism, enabling the passive roller to move horizontally outward to one side of the laminating equipment. The displacement can be adjusted according to actual needs. This design allows for precise and automatic adjustment of the film tension during the laminating process, based on different film specifications, materials, and laminating process requirements. This effectively avoids defects such as wrinkles and bubbles caused by uneven or unsuitable film tension, improving laminating quality and meeting diverse production needs. The assembly plate structure allows the entire guide roller mechanism to be compactly installed on the laminating equipment without occupying additional space, significantly reducing the overall volume of the laminating equipment. This solves the problems of large space occupation and difficult equipment layout associated with traditional guide roller mechanisms, improving the effective utilization of production space. It allows for convenient and quick assembly during use and can be disassembled into individual components for transportation or storage, further reducing the space occupied by the laminating equipment. Compared to traditional complex guide roller mechanisms, this significantly reduces transportation and storage costs, improving the portability and flexibility of the equipment.

[0008] Furthermore, the guiding mechanism includes: a first guide rod, which is perpendicularly connected to the second mounting surface of the mounting plate; a second guide rod, which is perpendicularly connected to the second mounting surface of the mounting plate; and a driving mechanism located between the first guide rod and the second guide rod.

[0009] By adopting the above scheme, the design of two guide rods significantly enhances the anti-interference capability of the guiding mechanism compared to a single-rod structure, ensuring a stable structure between the guide rods and the assembly plate. When the guide roller frame reciprocates linearly along the guiding mechanism, the vertical connection effectively distributes the force generated by the motion evenly onto the assembly plate, reducing structural deformation or loosening caused by uneven force distribution, thereby ensuring the stability and reliability of the entire adjustable guide roller mechanism during long-term operation.

[0010] Furthermore, the guide roller frame includes a first guide hole and a second guide hole spaced apart, the first guide rod passes through the first guide hole, the second guide rod passes through the second guide hole, the diameter of the first guide hole is greater than or equal to the diameter of the first guide rod, and the diameter of the second guide hole is greater than or equal to the diameter of the second guide rod.

[0011] By adopting the above scheme, a clear linear guiding path is provided for the movement of the guide roller frame. Even if the guide roller frame reciprocates under the action of the drive mechanism, it can move accurately along the direction of the guide rod, ensuring that the passive roller can adjust its position according to the predetermined trajectory, thereby precisely controlling the film tension and improving the coating quality.

[0012] Furthermore, a first sliding sleeve is slidably sleeved on the first guide rod, and a second sliding sleeve is slidably sleeved on the second guide rod. The first sliding sleeve passes through the first guide hole and is fixed to the guide roller frame, and the second sliding sleeve passes through the second guide hole and is fixed to the guide roller frame.

[0013] By adopting the above-mentioned scheme, the sliding sleeve is typically made of a material with good self-lubricating properties. Compared to the direct contact between the guide rod and the guide hole of the guide roller frame, the coefficient of friction between the sliding sleeve and the guide rod is lower. This results in less frictional resistance and smoother movement when the guide roller frame moves linearly along the guide rod under the drive mechanism, reducing energy loss and improving equipment operating efficiency. The fit clearance between the sliding sleeve and the guide rod is uniform, and the surface of the sliding sleeve has a high degree of smoothness. During the movement of the guide roller frame, this uniform fit and smooth surface effectively reduce vibration and swaying during movement, making the movement of the guide roller frame more stable. Stable movement is crucial for accurately adjusting the film tension, ensuring uniform film tension during the lamination process and avoiding quality problems such as wrinkles and bubbles.

[0014] Furthermore, the ends of the first sliding sleeve and the second sliding sleeve are provided with mounting lips, and the mounting lips are provided with mounting screw holes.

[0015] By adopting the above scheme, the mounting screw holes on the mounting lip plate provide a precise and reliable fixed position for the connection between the sliding sleeve and the guide roller frame. Fastening the sliding sleeve and guide roller frame with bolts through the mounting screw holes ensures a tight connection, guaranteeing that the sliding sleeve will not loosen or shift relative to the guide roller frame during linear reciprocating motion, thus ensuring the stability and reliability of the entire guiding mechanism.

[0016] Furthermore, the inner diameter of the first sliding sleeve is the same as the diameter of the first guide rod, and the outer diameter of the first sliding sleeve is the same as the diameter of the first guide hole; the inner diameter of the second sliding sleeve is the same as the diameter of the second guide rod, and the outer diameter of the second sliding sleeve is the same as the diameter of the second guide hole.

[0017] By adopting the above scheme, the inner diameter of the sliding sleeve is consistent with the diameter of the guide rod, forming a tight fit. This tight fit ensures that the sliding sleeve can only move linearly along the axis of the guide rod, effectively limiting the radial and circumferential displacement of the sliding sleeve, thus providing precise linear guidance for the guide roller frame. In laminating equipment, precise guidance ensures that the passive roller is accurately positioned, allowing for precise control of the film tension and improving the quality and accuracy of laminating. The outer diameter of the sliding sleeve is consistent with the diameter of the guide hole, further enhancing the accuracy of guidance. It prevents the sliding sleeve from wobbling or shifting within the guide hole, avoiding deviations in the guide roller frame movement caused by unstable sliding sleeve position. Even under prolonged equipment operation or external interference, the accuracy of guidance remains unaffected, ensuring the stability and consistency of the laminating process.

[0018] Furthermore, the fixing plate is provided with a first fixing hole and a second fixing hole. The first fixing hole and the second fixing hole are both provided with an adjustable gap on the same side near the fixing plate. Clamping arms are provided on both sides of the adjustable gap, and the clamping arms are provided with coaxial adjusting screw holes.

[0019] By adopting the above solution, the adjustable gap design allows the fixing plate to accommodate various connectors of different diameters or sizes. In practical applications, situations may arise where connector specifications are inconsistent due to procurement differences or design changes. By adjusting the size of the adjustable gap, the fixing plate can securely fix bolts, shafts, or other connecting components of different specifications without requiring reprocessing or replacement of the fixing plate, greatly improving its versatility and flexibility in installation.

[0020] Furthermore, a reinforcing member is fitted on the first fixing hole and the second fixing hole, and the reinforcing member is provided with a locking screw hole corresponding to the first fixing hole and the second fixing hole respectively.

[0021] By adopting the above solution, an additional threaded connection area is provided for bolts and other connecting components. Compared to relying solely on the threads of the fixing plate for connection, the reinforcing member expands the engagement length and area of ​​the threads. This allows the bolt to form a tighter and more secure bond with the reinforcing member and the fixing plate when tightened, significantly improving the tensile and shear strength of the connection, enabling it to withstand greater external forces without loosening or falling off.

[0022] Furthermore, two support plates are vertically arranged on the guide roller frame, and a shaft is hinged between the support plates, with the passive roller sleeved on the shaft.

[0023] By adopting the above solution, the weight of the passive roller and the material it carries is effectively borne, as well as various dynamic loads generated during equipment operation, such as vibration and impact. Even under heavy load or high-speed operation conditions, the position of the passive roller can be kept stable without swaying or shifting, thus ensuring the normal operation of the equipment and processing accuracy.

[0024] A film coating device employing an adjustable passive roller unit.

[0025] By adopting the above solution, the utilization rate of the coating equipment is improved, the operating space occupied by the passive roller in the coating equipment is greatly reduced, and the assembly space is reduced.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This guide roller mechanism drives the guide roller frame to reciprocate linearly along the guiding mechanism via a drive mechanism, enabling the passive roller to move horizontally outward to one side of the laminating equipment. The displacement can be flexibly adjusted according to actual needs. During the laminating process, it can accurately and automatically adjust the film tension for films of different specifications and materials, as well as diverse laminating process requirements. This effectively avoids defects such as wrinkles and bubbles caused by uneven or unsuitable film tension, significantly improving the appearance quality and overall quality of the laminated products. Because it can flexibly adjust the film tension, this guide roller mechanism can adapt well to laminating different types of films, regardless of film thickness or elasticity, or production scenarios with different requirements for laminating precision. It can meet the corresponding process requirements, thereby expanding the application range of the laminating equipment and enhancing its versatility and adaptability. 2. The assembly plate design allows the entire guide roller mechanism to be compactly installed on the laminating equipment without requiring additional space. This compact installation method significantly reduces the overall size of the laminating equipment, solving the problem of difficult equipment layout caused by the complex structure and large space occupation of traditional guide roller mechanisms. It improves the effective utilization of production space, allowing limited production space to accommodate more equipment or achieve a more rational layout. During use, the guide roller mechanism can be easily and quickly assembled; and during transportation or storage, it can be disassembled into individual components. This detachable design further reduces the space occupied by the laminating equipment during transportation and storage, reducing transportation and storage costs, improving the portability and flexibility of the equipment, and facilitating its transfer and deployment between different production sites. 3. Because this guide roller mechanism is detachable and occupies little space, it can reduce the number of transport vehicles used or lower the cargo space requirements of transport vehicles during transportation, thereby reducing transportation costs. During storage, it can also reduce warehouse space usage and lower warehousing costs. Compared with traditional complex guide roller mechanisms, this adjustable guide roller mechanism has a relatively simple structure and fewer parts. This not only makes the assembly and disassembly of the equipment simpler, eliminating the need for complex operations by professional technicians and saving time and labor costs, but also reduces the probability of equipment failure, lowers the difficulty and cost of equipment maintenance, and extends the service life of the equipment. 4. Operators can quickly assemble and disassemble the equipment following simple steps. No complex tools or professional technical training are required, greatly improving deployment efficiency, reducing downtime, and contributing to increased production efficiency. During equipment commissioning, operators can easily adjust and optimize the guide roller mechanism to achieve the best coating effect; in daily maintenance, they can easily inspect, clean, and replace various components, ensuring normal equipment operation and reducing the difficulty and workload of equipment maintenance.

[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 3As shown, an adjustable passive roller unit is provided, including an assembly plate 1, a guiding mechanism 2, a driving mechanism 4, and a guide roller frame 5. The assembly plate 1 has a first assembly surface 11 and a second assembly surface 12 opposite to the first assembly surface 11. The first assembly surface 11 of the assembly plate 1 is securely assembled to the side wall of the laminating equipment using conventional connectors such as bolts, ensuring a firm and reliable connection between the assembly plate 1 and the side wall of the laminating equipment, providing a stable mounting base for the entire adjustable guide roller mechanism. The guiding mechanism 2 includes a first guide rod 21 and a second guide rod 22, both of which are perpendicularly connected to the second assembly surface 12 of the assembly plate 1. In specific operation, bolts can be used to fix one end of the first guide rod 21 and the second guide rod 22 to appropriate positions on the second assembly surface 12 of the assembly plate 1, ensuring that the two guide rods are parallel to each other and perpendicular to the assembly plate 1. An installation space for the driving mechanism 4 is reserved between the first guide rod 21 and the second guide rod 22. Then, a fixing plate 3 is installed on the other end of the first guide rod 21 and the second guide rod 22, also secured with bolts, ensuring the overall stability of the guiding mechanism 2. The drive mechanism 4 is mounted on the fixed plate 3.

[0039] The guide roller frame 5 includes a first guide hole 51 and a second guide hole 52 spaced apart. A first guide rod 21 passes through the first guide hole 51, and a second guide rod 22 passes through the second guide hole 52, ensuring that the guide roller frame 5 can slide smoothly along the guide rods. To make the movement of the guide roller frame 5 smoother, in this embodiment 1, a first sliding sleeve 6 is slidably fitted on the first guide rod 21, and a second sliding sleeve 7 is slidably fitted on the second guide rod 22. The first sliding sleeve 6 passes through the first guide hole 51 and is fixed to the guide roller frame 5 with bolts, and the second sliding sleeve 7 passes through the second guide hole 52 and is fixed to the guide roller frame 5 with bolts. The ends of the first sliding sleeve 6 and the second sliding sleeve 7 are provided with mounting lips 71, and the mounting lips 71 are provided with mounting screw holes 72. The sliding sleeves are fastened to the guide roller frame 5 by bolts passing through the mounting screw holes 72, ensuring the stability of the connection. At the same time, it is necessary to ensure that the diameter of the first guide hole 51 is greater than or equal to the diameter of the first guide rod 21, the diameter of the second guide hole 52 is greater than or equal to the diameter of the second guide rod 22, the inner diameter of the first sliding sleeve 6 is the same as the diameter of the first guide rod 21, and the outer diameter of the first sliding sleeve 6 is the same as the diameter of the first guide hole 51; the inner diameter of the second sliding sleeve 7 is the same as the diameter of the second guide rod 22, and the outer diameter of the second sliding sleeve 7 is the same as the diameter of the second guide hole 52, so as to achieve precise guidance and stable movement.

[0040] It should be noted that the drive mechanism 4 can be selected according to actual production needs, such as a push rod motor, lead screw motor, cylinder, or hydraulic cylinder. The selected drive mechanism 4 is assembled onto the fixed plate 3. If the drive mechanism 4 is a motor, it can be fixed to the pre-set installation position on the fixed plate 3 with bolts; if it is a cylinder or hydraulic cylinder, it is reliably connected to the fixed plate 3 using appropriate connectors, ensuring that the drive end of the drive mechanism 4 faces the guide roller frame 5 for subsequent connection. The guide roller frame 5 is then connected to the drive end of the drive mechanism 4. For example, if the drive mechanism 4 is a motor, the output shaft of the motor can be connected to the connecting shaft on the guide roller frame 5 using a coupling; if it is a cylinder or hydraulic cylinder, a piston rod is used to connect to the connector on the guide roller frame 5, ensuring that the drive mechanism 4 can drive the guide roller frame 5 to perform linear reciprocating motion along the guide mechanism 2.

[0041] In some embodiments, the fixing plate 3 is provided with a first fixing hole 31 and a second fixing hole 32. Adjustable gaps 33 are provided on the same side of the first fixing hole 31 and the second fixing hole 32 near the fixing plate 3. Clamping arms 34 are provided on both sides of the adjustable gaps 33, and the clamping arms 34 are provided with coaxial adjusting screw holes 35. During actual installation, the size of the adjustable gap 33 is adjusted according to the specifications of the connecting parts by adjusting the depth of the adjusting bolts screwed into the adjusting screw holes 35, so that the fixing plate 3 can adapt to connecting parts such as bolts and shafts of different specifications. Simultaneously, reinforcing members 36 are assembled on the first fixing hole 31 and the second fixing hole 32. The reinforcing members 36 are respectively provided with locking screw holes 37 corresponding to the first fixing hole 31 and the second fixing hole 32. The reinforcing members 36 are tightly connected to the fixing plate 3 by bolts, enhancing the connection's firmness.

[0042] 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 55 is sleeved on the shaft 54, so that the passive roller 55 can rotate with the rotation of the shaft 54, thus completing the installation of the passive roller 55.

[0043] This utility model also relates to a laminating device that uses an adjustable passive roller unit, which can improve the utilization rate of the laminating device, greatly reduce the operating space occupied by the passive roller, and reduce the assembly space.

[0044] During assembly, the assembly plate 1 is bolted to the side wall of the film coating equipment. The guide rod is welded to the second assembly surface 12 of the assembly plate 1, the sliding sleeve is pressed into the guide hole, the guide roller frame 5 is fixed by the lip plate bolt, the push rod motor base is locked to the fixed plate 3, the telescopic end is connected to the interface of the guide roller frame 5, the shaft 54 ​​is inserted into the inner cavity bearing of the passive roller 55, and both ends are inserted into the opening groove of the support plate 53.

[0045] When the push rod motor is started: the telescopic end pushes the guide roller frame 5 to move horizontally along the guide rod, with a stroke range of ±50mm. The sliding sleeve slides on the surface of the guide rod, with a friction coefficient ≤0.08. The position of the passive roller 55 changes in real time to achieve dynamic adjustment of the film tension; if the tension is insufficient, it moves outward by 5-10mm.

[0046] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This guide roller mechanism drives the guide roller frame 5 to reciprocate linearly along the guide mechanism 2 via the drive mechanism 4, enabling the passive roller 55 to move horizontally to one side of the laminating equipment. The displacement can be flexibly adjusted according to actual needs. During the laminating process, it can accurately and automatically adjust the film tension for films of different specifications and materials, as well as diverse laminating process requirements. This effectively avoids defects such as wrinkles and bubbles caused by uneven or unsuitable film tension, significantly improving the appearance quality and overall quality of the laminated products. Because it can flexibly adjust the film tension, this guide roller mechanism can adapt well to laminating different types of films, regardless of film thickness or elasticity, or production scenarios with different requirements for laminating precision. It can meet the corresponding process requirements, thereby expanding the application range of the laminating equipment and enhancing its versatility and adaptability. 2. The design of assembly plate 1 allows the entire guide roller mechanism to be compactly installed on the laminating equipment without requiring additional space. This compact installation method significantly reduces the overall size of the laminating equipment, solving the problem of difficult equipment layout caused by the complex structure and large space occupation of traditional guide roller mechanisms. It improves the effective utilization rate of production space, allowing limited production space to accommodate more equipment or achieve a more rational layout. During use, the guide roller mechanism can be easily and quickly assembled; and during transportation or storage, it can be disassembled into individual components. This detachable design further reduces the space occupied by the laminating equipment during transportation and storage, reducing transportation and storage costs, improving the portability and flexibility of the equipment, and facilitating the transfer and allocation of equipment between different production sites. 3. Because this guide roller mechanism is detachable and occupies little space, it can reduce the number of transport vehicles used or lower the cargo space requirements of transport vehicles during transportation, thereby reducing transportation costs. During storage, it can also reduce warehouse space usage and lower warehousing costs. Compared with traditional complex guide roller mechanisms, this adjustable guide roller mechanism has a relatively simple structure and fewer parts. This not only makes the assembly and disassembly of the equipment simpler, eliminating the need for complex operations by professional technicians and saving time and labor costs, but also reduces the probability of equipment failure, lowers the difficulty and cost of equipment maintenance, and extends the service life of the equipment. 4. Operators can quickly assemble and disassemble the equipment following simple steps. No complex tools or professional technical training are required, greatly improving deployment efficiency, reducing downtime, and contributing to increased production efficiency. During equipment commissioning, operators can easily adjust and optimize the guide roller mechanism to achieve the best coating effect; in daily maintenance, they can easily inspect, clean, and replace various components, ensuring normal equipment operation and reducing the difficulty and workload of equipment maintenance.

[0047] 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.
