Description

Technical Field

[0001] This utility model relates to the field of guide roller technology, and in particular to a guide roller mechanism for a film coating equipment. Background Technology

[0002] In the operation of laminating equipment, the guide roller mechanism is one of the key components, and its performance directly affects the laminating quality and production efficiency. Existing guide roller mechanisms in laminating equipment have many problems in practical applications.

[0003] On the one hand, traditional guide roller mechanisms typically employ a fixed installation method, which severely limits the flexibility of the guide rollers during the lamination process. When faced with laminated products of different specifications and shapes, it is difficult to quickly and accurately adjust the position and angle of the guide rollers to adapt to diverse production needs. For example, when producing irregularly shaped packaging films, fixed guide rollers cannot be adjusted according to the specific shape of the product, leading to quality problems such as wrinkles and misalignment during the lamination process, seriously affecting the product qualification rate.

[0004] On the other hand, existing guide roller mechanisms generate a large amount of heat during long-term operation due to the high-speed friction between the guide rollers and the film material. If this heat cannot be dissipated effectively in a timely manner, the temperature of the guide rollers will rise sharply. High temperatures will not only cause the film material to deform due to heat, affecting the flatness and accuracy of the coating, but also accelerate the wear of the guide roller surface, shorten the service life of the guide rollers, increase equipment maintenance costs and downtime, and thus reduce overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to disclose a guide roller mechanism for a film coating equipment, which effectively solves the problems of existing guide roller mechanisms in terms of flexibility, heat dissipation and drive.

[0006] To achieve the above objectives, this utility model discloses a guide roller mechanism for a film coating equipment, comprising: an operating table; a turntable mechanism rotatably connected to the operating table; a driving mechanism mounted on the operating table for driving the turntable mechanism to rotate; a guide roller assembly mounted on the turntable mechanism for rotating at the same frequency as the turntable mechanism; and a cooling unit disposed within the guide roller assembly for cooling the guide roller assembly.

[0007] By adopting the above solution, the guide roller assembly can flexibly adjust its position and angle according to the specifications and shapes of different coated products. When producing irregularly shaped packaging films, simply adjusting the rotation angle of the turntable by controlling the drive mechanism allows the guide roller assembly to quickly adapt to the special shape of the product, effectively avoiding problems such as wrinkles and misalignment during the coating process, and greatly improving the product qualification rate. A cooling unit is installed inside the guide roller assembly. This cooling unit can promptly conduct heat away when the guide roller and film material generate heat through friction, cooling the guide roller assembly. This heat dissipation design effectively prevents the film material from deforming due to excessively high guide roller temperature, ensuring the flatness and accuracy of the coating. At the same time, it reduces the wear on the guide roller surface, extends the service life of the guide roller, reduces equipment maintenance costs and downtime, and improves overall production efficiency.

[0008] Furthermore, the guide roller assembly includes a roller body made of a high thermal conductivity metal. The roller body is provided with at least one cooling channel arranged along its axial direction. The cooling channel is provided with a cooling pipe, and the cooling pipe is filled with coolant.

[0009] By adopting the above solution, the high thermal conductivity metal possesses excellent thermal conductivity, enabling it to quickly conduct the heat generated by the friction between the guide roller and the film material from the heat-generating area to the entire roller surface, providing a good foundation for subsequent heat dissipation. The cooling pipes are in direct contact with the inside of the roller, quickly absorbing the heat conducted from the roller and carrying it out of the guide roller assembly through the flow of coolant. The coolant can be selected according to the appropriate type and performance parameters based on actual production needs to meet the cooling requirements under different operating conditions.

[0010] Furthermore, the cooling pipe includes a cooling channel, a coolant outlet, and a coolant inlet, and the coolant outlet and coolant inlet are equipped with sealing valves.

[0011] By adopting the above solution, it is convenient to replenish and replace the coolant. The static coolant can fully fill the cooling pipes and cooling channels, maximizing its heat capacity to absorb heat. When the guide roller temperature rises, the static coolant can quickly absorb a large amount of heat while its own temperature change is relatively small, thus effectively slowing down the rate of temperature rise of the guide roller and providing more time to ensure the stable progress of the coating process.

[0012] Furthermore, the cooling channel forms an opening in the roller body for direct contact with the coating on the surface of the roller body.

[0013] By adopting the above scheme, the cooling channel opening directly contacts the film, allowing the cooling medium to exchange heat more directly and fully with the film and roller surface.

[0014] Furthermore, a phase change material is filled between the cooling channel and the cooling pipe.

[0015] By adopting the above solution, the guide roller assembly generates a large amount of heat during the operation of the coating equipment. The phase change material filled between the cooling channels and cooling pipes can quickly absorb this heat, achieving efficient thermal management. When the temperature of the guide roller assembly suddenly rises, the phase change material can react rapidly, absorbing a large amount of heat through phase change, preventing damage to the guide roller and coating caused by a sharp temperature rise.

[0016] Furthermore, the roller body surface is coated with a rubber layer, and the rubber layer surface is provided with micro-protrusions or a mesh pattern.

[0017] By employing the above-mentioned method, the micro-bumps or textures on the surface of the coating layer increase the contact area with the film material, while simultaneously generating a microscopic mechanical interlocking effect. During the lamination process, this mechanical interlocking allows the film material to adhere more tightly to the roller surface, effectively preventing film slippage or displacement, thereby significantly improving the adhesion between the film material and the substrate, making the lamination more robust, and reducing the probability of quality problems such as peeling or curling after lamination. The micro-bumps or textures can also form tiny air channels between the film material and the roller. When the film material is transported on the roller, these air channels help to expel air between the film material and the roller, avoiding the formation of air bubbles due to air accumulation, allowing the film material to adhere more smoothly to the substrate, improving the flatness and uniformity of the lamination, and enhancing the appearance quality of the product.

[0018] Furthermore, the drive mechanism includes: a drive frame, which is fixedly connected to the operating table; a drive component, which is assembled inside the drive frame; and a transmission component, which is used to transmit the power from the output end of the drive component to the turntable mechanism.

[0019] By adopting the above solution and fixing the drive frame to the operating table, a stable and reliable support foundation can be provided for the entire drive mechanism. During the process of the drive components generating power and transmitting it to the turntable mechanism through the transmission components, vibration and reaction forces are inevitably generated. A robust connection method can effectively disperse these forces, preventing displacement or swaying of the drive mechanism due to its own vibration, and ensuring the stability and reliability of the drive mechanism during long-term operation.

[0020] Furthermore, the turntable mechanism includes: a turntable; a turntable shaft, the turntable shaft being assembled at the center of the turntable, and the two rotating synchronously; and a bearing, the bearing being rotatably sleeved on the turntable shaft and mounted on the operating table.

[0021] By adopting the above solution, it can be ensured that power is accurately transmitted from the drive mechanism to the turntable. During the operation of the laminating equipment, the power generated by the drive mechanism acts on the turntable shaft through the transmission components. Since the turntable and the turntable shaft rotate synchronously, the power can efficiently and directly drive the turntable to rotate at a predetermined speed and direction, avoiding problems such as unstable turntable rotation and uneven speed caused by inaccurate power transmission, thereby ensuring the precision and consistency of the laminating process.

[0022] Furthermore, a coolant pipe is provided inside the turntable shaft, and the coolant pipe is connected to the cooling pipe inside the guide roller assembly. A coolant replenishment port is provided at the end of the turntable shaft away from the guide roller assembly.

[0023] By adopting the above solution, the turntable continuously rotates during the operation of the coating equipment. The process of contact with the film material and the work performed by the drive mechanism generates heat. The turntable shaft, as the core support and transmission component of the turntable, also heats up due to friction and conduction. A coolant pipe is installed inside the turntable shaft, allowing the coolant to flow directly through the shaft body for precise cooling. This effectively removes the heat generated by the shaft due to the aforementioned reasons, preventing problems such as thermal expansion and deformation caused by overheating, and ensuring the dimensional accuracy and mechanical performance of the turntable shaft. The coolant replenishment port ensures that the coolant can be replaced or replenished in a timely manner, allowing the internal static coolant to be replaced when the temperature rises.

[0024] Furthermore, a connecting post is provided at one end of the turntable shaft facing the guide roller assembly, and a series of linearly arranged locking blocks are provided on the circumference of the connecting post along the axial direction. The locking blocks engage with the roller body of the guide roller assembly to drive the guide roller assembly to rotate synchronously.

[0025] By adopting the above scheme, the snap-fit ​​blocks arranged linearly along the axial direction of the connecting column snap into the roller body of the guide roller assembly. This design enables efficient and precise power transmission between the turntable shaft and the guide roller assembly. When the turntable shaft rotates, the snap-fit ​​blocks directly transmit torque to the roller body. Due to the tight fit of the snap-fit ​​structure, there is almost no power loss during transmission, ensuring that the guide roller assembly and the turntable shaft rotate synchronously. This guarantees the coordination of the movement of various components during the lamination process and improves the accuracy and quality of lamination.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional guide roller mechanisms are difficult to adjust when faced with laminated products of different specifications and shapes due to their fixed installation. The guide roller assembly of this utility model is assembled on a rotatable turntable mechanism. When producing diverse products such as irregularly shaped packaging films, the guide roller assembly can quickly adapt to the special shape of the product by simply adjusting the rotation angle of the turntable through the control of the drive mechanism, thus meeting diverse production needs. 2. By setting a cooling unit inside the guide roller assembly, heat can be absorbed and exchanged in a timely manner when it is generated, effectively preventing the deformation of the film material due to heat, ensuring the quality of the coated product. The heat dissipation design of the cooling unit reduces the working temperature of the guide roller, reduces the damage of high temperature to the guide roller material, reduces the wear of the guide roller surface, thereby extending the service life of the guide roller and reducing equipment maintenance costs and downtime. 3. The drive mechanism is mounted on the operating table and drives the turntable to rotate, while the guide roller assembly rotates at the same frequency as the turntable mechanism. This design ensures the stability and coordination of the guide roller assembly during rotation, avoiding problems such as guide roller wobbling and jamming caused by asynchronous driving, and improving the stability and reliability of the coating process; 4. By flexibly adjusting the position and angle of the guide roller assembly and employing an effective heat dissipation design, this invention effectively avoids quality problems such as wrinkles and misalignment during the lamination process. During production, the guide rollers better guide the film material, ensuring it covers the product surface smoothly and evenly, significantly improving the product's pass rate and enhancing its market competitiveness.

[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] Please refer to Embodiment 1 of this utility model. Figures 1 to 4 As shown in the figure, this application embodiment provides a guide roller mechanism for a laminating equipment, including an operating table 1, a turntable mechanism 2, a drive mechanism 3, a guide roller assembly 4, and a cooling unit 5. The operating table 1 serves as the supporting foundation for the entire mechanism, providing a stable mounting platform for other components. The turntable mechanism 2 is rotatably connected to the operating table 1 and can rotate under the drive of the drive mechanism 3. The drive mechanism 3 is installed on the operating table 1 and provides power for the rotation of the turntable 21. The guide roller assembly 4 is mounted on the turntable mechanism 2 and rotates at the same frequency as the turntable mechanism 2 to guide the film material for laminating operations. The cooling unit 5 is located inside the guide roller assembly 4 and is responsible for cooling and heat dissipating the guide roller assembly 4 to ensure the stability of the laminating process and product quality. This allows the guide roller assembly 4 to flexibly adjust its position and angle according to the specifications and shapes of different laminating products. When producing irregularly shaped packaging films, the guide roller assembly 4 can quickly adapt to the special shape of the product simply by controlling the drive mechanism 3 to adjust the rotation angle of the turntable 21, effectively avoiding problems such as wrinkles and offsets during the laminating process and greatly improving the product qualification rate. A cooling unit 5 is installed inside the guide roller assembly 4. This cooling unit 5 can promptly conduct heat away when the guide roller generates heat through friction with the film material, thus cooling the guide roller assembly 4. This heat dissipation design effectively prevents the film material from deforming due to excessively high guide roller temperature, ensuring the flatness and accuracy of the coating. At the same time, it reduces the wear on the guide roller surface, extends the service life of the guide roller, reduces equipment maintenance costs and downtime, and improves overall production efficiency.

[0040] Specifically, the operating table 1 is made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure sufficient load-bearing capacity and stability. It is rectangular flat, with a finely machined surface, and the flatness error is controlled within a very small range, providing a precise reference surface for the installation of other components. Mounting holes 11 are provided at the four corners of the operating table 1, which are then fixedly connected to the frame of the coating equipment with bolts, ensuring that the operating table 1 will not shake or shift during equipment operation.

[0041] The turntable mechanism 2 includes a turntable 21, a turntable shaft 22, and a bearing 23. The turntable 21 is also made of high-strength metal material and is circular in shape. Its diameter is designed according to the specifications of the coating equipment and actual production needs. The surface of the turntable 21 is polished to reduce friction with the film material and reduce film wear. The turntable shaft 22 is made of high-quality alloy steel and has high strength and rigidity. The turntable shaft 22 is assembled in the center of the turntable 21, and the two are connected by a key or interference fit to achieve synchronous rotation. One end of the turntable shaft 22 is provided with a connecting post 221, and multiple locking blocks 2211 are linearly arranged circumferentially along the axial direction of the connecting post 221. The locking blocks 2211 are trapezoidal or rectangular in shape, and their size and number are designed according to the structure of the roller body 41 of the guide roller assembly 4 to ensure tight engagement with the roller body 41 and achieve efficient torque transmission. The bearing 23 is a high-precision rolling bearing, such as a deep groove ball bearing or a tapered roller bearing, which is rotatably fitted onto the turntable shaft 22. The bearing 23 is installed in a pre-machined bearing seat or through hole on the operating table 1, and is fixed and sealed by a bearing cover. The bearing 23 requires high installation precision; its radial and axial clearances must be controlled within specified ranges to ensure smooth and flexible rotation of the turntable shaft 22, reducing friction and wear. By adopting the above scheme, power can be accurately transmitted from the drive mechanism 3 to the turntable 21. During the operation of the coating equipment, the power generated by the drive mechanism 3 acts on the turntable shaft 22 through the transmission component 33. Since the turntable 21 rotates synchronously with the turntable shaft 22, the power can efficiently and directly drive the turntable 21 to rotate at a predetermined speed and direction, avoiding problems such as unstable rotation and uneven speed of the turntable 21 caused by inaccurate power transmission, thereby ensuring the accuracy and consistency of the coating process.

[0042] The drive mechanism 3 includes a drive frame 31, a drive component 32, and a transmission component 33. The drive frame 31 is welded from steel and has sufficient strength and rigidity. The drive frame 31 is fixed to the operating table 1 with bolts, providing stable support for the drive component 32 and the transmission component 33. The shape of the drive frame 31 is designed according to the layout of the drive component 32 and the transmission component 33 to ensure sufficient installation space and movement clearance between the components. The drive component 32 uses a servo motor, which has advantages such as high precision, fast response, and wide speed range. The servo motor is assembled inside the drive frame 31 and fixed with bolts. The output shaft of the motor is connected to the transmission component 33. The control system can precisely control the speed and direction of the motor, thereby achieving precise control of the rotation angle and speed of the turntable 21. The transmission component 33 transmits the power from the output end of the drive component 32 to the turntable mechanism 2 using synchronous belt drive or gear drive. If synchronous belt drive is used, high-precision synchronous belts and pulleys must be selected to ensure the accuracy and stability of the transmission. Synchronous belt pulleys are mounted on the motor output shaft and turntable shaft 22 respectively via key connections or shrink sleeve connections. If gear transmission is used, high-precision gear pairs must be selected, and the gear tooth profile and module must be designed according to the transmission ratio and load-bearing capacity. The gears are mounted on the drive frame 31 and the operating table 1 via bearings 23 and are lubricated with lubricating oil to reduce wear and noise. This embodiment 1 uses a transmission belt drive connection.

[0043] The guide roller assembly 4 includes a roller body 41 and a cooling pipe 42. The roller body 41 is made of a high thermal conductivity metal, such as copper alloy or aluminum alloy, to improve heat conduction performance. At least one cooling channel 411 is provided within the roller body 41 along its axial direction. The cooling channel 411 is circular or rectangular in shape, and its dimensions are designed according to the diameter of the roller body 41 and cooling requirements. The cooling channel 411 forms openings on the surface of the roller body 41 for direct contact with the coating film, thereby enhancing heat dissipation. The surface of the roller body 41 is coated with an adhesive layer 412, which is made of rubber or polyurethane material, possessing good elasticity and wear resistance. The surface of the adhesive layer 412 is provided with micro-protrusions or a mesh pattern. The micro-protrusions are hemispherical or conical in shape, and the mesh pattern is rhomboid or square in shape. Their size and density are designed according to the requirements of the coated product to increase the contact area and adhesion with the film material. The cooling pipe 42 is disposed within the cooling channel 411 and is made of copper or stainless steel, possessing good thermal conductivity and corrosion resistance. Cooling pipe 42 is filled with coolant 51, which can be water, ethylene glycol solution, or other dedicated cooling media, depending on actual production needs. Cooling pipe 42 is equipped with cooling channel 421, coolant outlet 422, and coolant inlet 423. Sealing valves 424 are installed at coolant outlet 422 and coolant inlet 423 for easy replenishment and replacement of coolant 51. Static coolant 51 can fully fill cooling pipe 42 and cooling channel 411, maximizing its heat capacity to absorb heat. When the guide roller temperature rises, static coolant 51 can quickly absorb a large amount of heat while its own temperature change is relatively small, effectively slowing down the temperature rise of the guide roller and providing more time for the stable operation of the coating process. Phase change material 425 is filled between cooling channel 421 and cooling pipe 42. Optionally, phase change material 425 can also be filled inside roller body 4. The phase change material 425 is selected from paraffin or inorganic salts, and its phase change temperature is selected according to the working temperature range of the guide roller assembly 4 in order to achieve efficient thermal management.

[0044] In some embodiments, optionally, a coolant 51 pipe is provided inside the turntable shaft 22, and the coolant 51 pipe is connected to the cooling pipe 42 inside the guide roller assembly 4. A coolant 51 replenishment port is provided at the end of the turntable shaft 22 away from the guide roller assembly 4. The turntable 21 rotates continuously during the operation of the coating equipment, and heat is generated during its contact with the film material and the work performed by the drive mechanism 3. As the core support and transmission component of the turntable 21, the turntable shaft 22 will also heat up due to friction, conduction, and other reasons. The coolant 51 pipe inside the turntable shaft 22 allows the coolant 51 to flow directly through the inside of the shaft, precisely cooling the turntable shaft 22 and effectively removing the heat generated by the shaft due to the above reasons. This prevents the shaft from thermally expanding and deforming due to overheating, ensuring the dimensional accuracy and mechanical performance of the turntable shaft 22. The coolant 51 replenishment port ensures that the coolant 51 can be replaced or replenished in a timely manner, allowing the internal static coolant 51 to be replaced after the temperature rises.

[0045] During operation of the laminating equipment, the servo motor in the drive mechanism 3 is first controlled by the control system to rotate according to the specifications and shape of the product to be laminated. The servo motor drives the turntable mechanism 2 to rotate through the transmission component 33, and the guide roller assembly 4 on the turntable mechanism 2 rotates synchronously. The rotation angle of the turntable 21 is adjusted according to the specific shape of the product, allowing the guide roller assembly 4 to quickly adapt to the product's shape requirements. During the laminating process, the guide roller assembly 4 guides the film material to smoothly cover the product surface, while the high-speed friction between the guide roller and the film material generates heat. The heat is conducted through the roller body 41 to the cooling pipe 42 and the phase change material 425. The coolant 51 in the cooling pipe 42 absorbs the heat and then flows out of the guide roller assembly 4 for heat dissipation. The phase change material 425 undergoes a phase change, absorbing a large amount of heat to prevent the guide roller temperature from becoming too high. The coolant 51 is replaced periodically to restore the temperature of the roller body 41 and the phase change material 425, achieving continuous cooling. The coolant 51 can be quickly replenished using a quick-connect coupling, or it can be replaced by a robotic arm, replacing manual operation.

Traditional guide roller mechanisms are difficult to adjust when faced with laminated products of different specifications and shapes due to their fixed installation. The guide roller assembly 4 of this utility model is assembled on a rotatable turntable mechanism 2. When producing diverse products such as irregularly shaped packaging films, the guide roller assembly 4 can quickly adapt to the special shape of the product by simply adjusting the rotation angle of the turntable 21 by controlling the drive mechanism 3, thus meeting diverse production needs. 2. By setting a cooling unit 5 inside the guide roller assembly 4, heat can be absorbed and exchanged in a timely manner when heat is generated, effectively preventing the deformation of the film material due to heat, ensuring the quality of the coated product. The heat dissipation design of the cooling unit 5 reduces the working temperature of the guide roller, reduces the damage of high temperature to the guide roller material, reduces the wear of the guide roller surface, thereby extending the service life of the guide roller and reducing equipment maintenance costs and downtime. 3. The drive mechanism 3 is mounted on the operating table 1 and drives the turntable 21 to rotate. The guide roller assembly 4 rotates at the same frequency as the turntable mechanism 2. This design ensures the stability and coordination of the guide roller assembly 4 during rotation, avoids problems such as guide roller swaying and jamming caused by asynchronous driving, and improves the stability and reliability of the coating process. 4. By flexibly adjusting the position and angle of the guide roller assembly 4 and employing an effective heat dissipation design, this invention can effectively avoid quality problems such as wrinkles and misalignment during the lamination process. During production, the guide rollers can better guide the film material, ensuring it covers the product surface smoothly and evenly, greatly improving the product's pass rate and enhancing its market competitiveness.
