Description
Technical Field
[0001] This utility model relates to the field of paper tube adhesive technology, and in particular to a double-sided adhesive mechanism for a pull-out type paper tube replacement for a coating machine. Background Technology
[0002] The pull-out structure allows the adhesive paper tube to be transferred to the outside of the wall panel for replacement, avoiding the risk of the paper tube falling onto the material surface due to errors during conventional internal replacement operations. The external replacement layout ensures that even if the paper tube accidentally falls, it will not come into contact with the protective film or release film being conveyed, thus eliminating the risk of the paper tube being carried away by the material and contaminating the coating surface. This also reduces material waste due to contamination, lowers material loss costs during production, and ensures the stability of the coated product quality. Compared to the complex replacement operations within the confined space of the wall panel, the external pull-out structure provides operators with a spacious working area, allowing for the removal and installation of the adhesive paper tube without needing to enter the equipment. This design simplifies the replacement process, making operation faster and more convenient. It not only reduces the skill requirements for operators but also reduces the probability of operational errors, improving the smoothness of equipment maintenance.
[0003] The internal replacement operation carries extremely high quality risks. The interior space of the wall panel is small and the line of sight is limited. When the operator is removing the old paper tube or installing the new paper tube, even a slight mistake may cause the paper tube to slip off, and the slipped paper tube is very likely to fall directly onto the substrate surface that is being conveyed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-sided adhesive coating mechanism for replacing paper tubes in a coating machine using a pull-out type.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided adhesive paper tube replacement mechanism for a coating machine, comprising an adhesive paper tube and a pull-out part, wherein two sets of mounting seats are arranged horizontally inside the assembly frame, and an adhesive roller is rotatably mounted between the mounting seats in the same set, the two adhesive rollers are arranged in parallel intervals, the coating material passes horizontally through the gap between the two adhesive rollers, the adhesive paper tube can be slidably mounted in the assembly frame in the horizontal direction through the pull-out part, and the outer circumferential surface of the adhesive paper tube is in contact with the outer circumferential surface of the adhesive roller, rotating synchronously with the adhesive roller.
[0006] Preferably, the pull-out part includes a track frame and a slide block. The track frame is fixedly assembled inside the assembly frame in the horizontal direction, and a lifting part is provided between the track frame and the assembly frame. The slide block can be slidably assembled along the length direction of the track frame. The bottom end of the slide block is fixedly engaged with both ends of the adhesive paper tube through a connecting part, thereby driving the adhesive paper tube to slide horizontally along the length direction of the track frame.
[0007] Preferably, the lifting part includes a cylinder and a telescopic part, which are arranged in parallel at intervals. The upper and lower ends of the cylinder and the telescopic part are respectively fixedly connected to the top of the inner wall of the assembly frame and the top surface of the track frame. When the piston rod of the cylinder extends or retracts, it drives the track frame to move up and down in the vertical direction, and simultaneously drives the slide and the adhesive paper tube to adjust the contact height with the adhesive roller in the vertical direction.
[0008] Preferably, the connecting part includes a connecting frame, a motor, a rectangular telescopic part, and a clamping seat. The connecting frame has a U-shaped structure, with its top end fixedly connected to the middle of the bottom end of the slide. Motors are detachably installed on both lower ends of the connecting frame. The output shafts of the two motors are coaxially opposite each other, and the axis of the output shaft is collinear with the axis of the adhesive paper tube. One end of the rectangular telescopic part is fixed to the output shaft of the motor through a coupling, and the other end is fixed to the clamping seat. The motor drives the rectangular telescopic part to drive the clamping seat to rotate around its own axis. The two clamping seats are respectively engaged with the two ends of the adhesive paper tube, driving the adhesive paper tube to rotate synchronously.
[0009] Preferably, it also includes a spring, which is sleeved on the outer periphery of the rectangular telescopic part. One end of the spring abuts against the end face of the coupling, and the other end abuts against the end face of the clamping seat. The spring is always in a compressed state, and pushes the clamping seat to move closer to the adhesive paper tube through elastic force, so that the clamping seat and the port of the adhesive paper tube are tightly abutted, and the two are prevented from sliding relative to each other.
[0010] Preferably, the port of the track frame is provided with a lubrication part, which stores lubricating oil and is arranged in accordance with the sliding path of the track frame. When the slide block slides along the track frame toward the lubrication part to a preset position, the lubricating oil can flow to the sliding contact surface between the slide block and the track frame, reducing the sliding friction between the two.
[0011] Preferably, the lubrication part includes an oil can, a plug, a sealing gasket, a slide rod, a magnetic block, and a sponge cover. The oil can is vertically fixed to the top surface of the end of the track frame. A plug is inserted into the top opening of the oil can. An oil passage hole is vertically opened in the middle of the plug. The sealing gasket is horizontally laid at the lower opening of the oil passage hole to seal it. The slide rod is vertically fixed to the middle of the bottom end of the sealing gasket. The lower end of the slide rod extends downward through the oil passage hole, and the bottom end of the slide rod is fixedly connected to the magnetic block. An installation groove is vertically opened at the bottom end of the plug, and the sponge cover is embedded in the installation groove. A magnetic plate is horizontally fixed in the middle of the upper end of the slide block. The side of the magnetic plate opposite to the magnetic block has the same magnetic pole. When the slide block slides to the position where the magnetic plate and the magnetic block are opposite, the same magnetic poles repel each other, pushing the magnetic block to drive the slide rod and the sealing gasket to move upward. The oil passage hole opens, and the lubricating oil flows to the slide block after being decelerated by the sponge cover.
[0012] Preferably, a piston is slidably connected inside the oil reservoir, and an air inlet is opened at the upper end of the side wall of the oil reservoir in the horizontal direction. By inflating the oil reservoir with air through the air inlet, the piston can be pushed to move along the length of the oil reservoir, thereby adjusting the oil pressure inside the oil reservoir and controlling the rate at which lubricating oil flows out from the oil passage.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a pull-out structure allows the adhesive paper tube to be transferred to the outside of the wall panel for replacement, avoiding the risk of the paper tube falling onto the material surface due to errors during conventional internal replacement operations. The external replacement layout ensures that even if the paper tube accidentally falls, it will not come into contact with the protective film or release film being conveyed, thus eliminating the risk of the paper tube being carried away by the material and contaminating the coating surface. It also reduces material waste due to contamination, lowers material loss costs during production, and ensures the stability of the coated product quality. Compared to the complex replacement operations within the confined space of the wall panel, the external pull-out structure provides operators with a spacious working area, allowing for the disassembly and installation of the adhesive paper tube without needing to enter the equipment. This design simplifies the replacement process, making operation faster and more convenient. It not only reduces the skill requirements for operators but also reduces the probability of operational errors, improving the smoothness of equipment maintenance. Attached Figure Description

[0016] Example 1, such as Figure 1-3As shown, the coating machine uses a pull-out type paper tube replacement double-sided adhesive coating mechanism, including an adhesive paper tube 13 and a pull-out part. The assembly frame 1 adopts a frame structure to facilitate the installation and layout of internal components. Two sets of mounting seats 2 are arranged horizontally inside the assembly frame 1. The two mounting seats 2 of the same set are symmetrically fixed on the two side walls inside the assembly frame 1. Adhesive rollers 3 are rotatably mounted between the mounting seats 2 of the same set. The two adhesive rollers 3 are arranged in parallel intervals. The coating material can pass horizontally through the gap between the two adhesive rollers 3 and can fully contact the surface of the adhesive rollers 3. The adhesive paper tube 13 can be slidably mounted in the assembly frame 1 horizontally through the pull-out part. The outer peripheral surface of the adhesive paper tube 13 is in contact with the outer peripheral surface of the adhesive roller 3, so that when the adhesive roller 3 rotates, it can drive the adhesive paper tube 13 to rotate synchronously. The two sets of adhesive rollers 3 can perform double-sided adhesive coating. The pull-out part includes a track frame 4 and a slide block 7. The track frame 4 is fixed in the middle area inside the assembly frame 1 along the length direction of the assembly frame 1. A lifting part is provided between the track frame 4 and the assembly frame 1. The slide block 7 and the track frame 4 adopt a sliding fit structure. The track frame 4 is provided with a sliding groove and the bottom of the slide block 7 is provided with a slider that matches the sliding groove, ensuring that the slide block 7 can slide smoothly along the length direction of the track frame 4. The bottom end of the slide block 7 is fixed to both ends of the adhesive paper tube 13 through a connecting part. When the slide block 7 slides, it can drive the adhesive paper tube 13 to slide horizontally along the length direction of the track frame 4. The lifting unit includes a cylinder 6 and a telescopic part 5. Two cylinders 6 and two telescopic parts 5 are provided and arranged in parallel intervals. The upper and lower ends of the cylinders 6 and 5 are respectively fixedly connected to the top of the inner wall of the assembly frame 1 and the top surface of the track frame 4. The cylinder body of the cylinder 6 is fixed to the top of the inner wall of the assembly frame 1 and the end of the piston 20 rod is fixed to the top surface of the track frame 4. The telescopic part 5 adopts a guide rod structure, with its upper end fixed to the top of the inner wall of the assembly frame 1 and its lower end fixed to the top surface of the track frame 4. When the piston 20 rod of the cylinder 6 extends or retracts, it can drive the track frame 4 to move up and down in the vertical direction. At the same time, the telescopic part 5 plays a guiding role to prevent the track frame 4 from deviating during lifting and lowering. In turn, it synchronously drives the slide 7 and the adhesive paper tube 13 to adjust the contact height with the adhesive roller 3 in the vertical direction. The connecting part includes a connecting frame 8, a motor 9, a rectangular telescopic part 10, and a clamping seat 12. The connecting frame 8 has a U-shaped structure and its top crossbar is welded and fixed to the middle of the bottom of the slide 7. The vertical bars on both sides of the connecting frame 8 extend downwards respectively. The motor 9 is detachably installed at the lower end of the vertical bar by bolts for easy maintenance and replacement. The output shafts of the two motors 9 are coaxially opposite each other and the output shaft axis is collinear with the axis of the ash-adhesive paper tube 13. The rectangular telescopic part 10 is a telescopic structure composed of an inner rod and an outer rod. One end of the rectangular telescopic part 10 is fixed to the output shaft of the motor 9 by a coupling and the other end is fixed to the clamping seat 12. The inner side of the clamping seat 12 is provided with a slot that matches the port of the ash-adhesive paper tube 13. The motor 9 drives the rectangular telescopic part 10 to drive the clamping seat 12 to rotate around its own axis. The two clamping seats 12 are respectively engaged with the two ports of the ash-adhesive paper tube 13 and drive the ash-adhesive paper tube 13 to rotate synchronously.The paper tube replacement also includes a spring 11, which is sleeved on the outer periphery of the rectangular telescopic part 10. One end of the spring 11 abuts against the end face of the coupling and the other end abuts against the end face of the clamping seat 12. The spring 11 is always in a compressed state and pushes the clamping seat 12 towards the direction of the adhesive paper tube 13 through its elastic force. Even if there is a slight dimensional deviation at the port of the adhesive paper tube 13, the elastic force of the spring 11 can compensate for the tight contact between the clamping seat 12 and the port of the adhesive paper tube 13, thus preventing the two from sliding relative to each other.
[0017] Working principle: In the initial state, the adhesive paper tube 13 is fixed by the clamping seat 12. The spring 11 is compressed, making the clamping seat 12 tightly abut against the end of the adhesive paper tube 13. The cylinder 6 drives the track frame 4, which in turn drives the slide 7 and the adhesive paper tube 13 to descend to a suitable height to be in contact with the adhesive roller 3. The telescopic part 5 acts as a guide to ensure that the track frame 4 rises and falls smoothly. During operation, the coating material passes horizontally through the gap between the two adhesive rollers 3. The adhesive roller 3 rotates and drives the adhesive paper tube 13 to rotate synchronously. At the same time, the motor 9 starts and drives the rectangular telescopic part 105 and the clamping seat 12 to rotate, further ensuring the stable rotation of the adhesive paper tube 13 to process the coating material. When it is necessary to adjust the horizontal position of the adhesive paper tube 13, the slide 7 slides along the length of the track frame 4, driving the adhesive paper tube 13 to move synchronously to the target position.
[0018] Example 2, based on Example 1, as follows: Figure 4As shown, the port of the track frame 4 is provided with a lubrication section. The lubrication section stores lubricating oil and is set according to the sliding path of the track frame 4. When the slide block 7 slides along the track frame 4 towards the lubrication section to a preset position, the lubricating oil can flow to the sliding contact surface between the slide block 7 and the track frame 4 to reduce the sliding friction between the two. The lubrication section includes an oil can 14, a plug 15, a sealing gasket 16, a slide rod 18, a magnet 19, and a sponge cover. The oil can 14 is vertically fixed to the top surface of the end of the track frame 4. The plug 15 is inserted into the top opening of the oil can 14. The middle of the plug 15 has an oil passage hole that runs vertically through it. The sealing gasket 16 is laid horizontally at the lower opening of the oil passage hole to seal it. The slide rod 18 is vertically fixed to the middle of the bottom end of the sealing gasket 16. The lower end of the slide rod 18 passes through the oil passage hole and extends downwards, and the bottom end of the slide rod 18 is fixedly connected to the magnet. Block 19 and plug 15 have a vertically oriented mounting groove 17 at their bottom ends. A sponge cover is embedded in the mounting groove 17 and has a porous structure to reduce the oil flow rate. A magnetic plate is fixedly connected to the upper end of the slide block 7 near the middle. The sides of the magnetic plate and magnetic block 19 that are close to each other are the same magnetic poles. When the slide block 7 slides to the position where the magnetic plate and magnetic block 19 are opposite each other, the same magnetic poles repel each other, pushing the magnetic block 19 to drive the slide rod 18 and sealing gasket 16 to move upward. After the oil passage is opened, the lubricating oil flows through the sponge cover at a reduced speed to the slide block 7. A piston 20 is slidably connected inside the oil reservoir 14. An air inlet 21 is installed horizontally on the upper end of the side wall of the oil reservoir 14. The air inlet 21 can be connected to an external air inflation device. When air is injected into the oil reservoir 14 through the air inlet 21, it can push the piston 20 to move along the length of the oil reservoir 14, thereby adjusting the oil pressure inside the oil reservoir 14 to control the rate at which the lubricating oil flows out from the oil passage.
[0019] Working principle: When the slide block 7 slides to the lubrication part near the port of the track frame 4, the magnetic plate on the slide block 7 and the magnetic block 19 below the plug 15 of the oil reservoir 14 repel each other due to their similar magnetic poles. This pushes the magnetic block 19, the slide rod 18, and the sealing gasket 16 upward, opening the oil passage. The lubricating oil in the oil reservoir 14 flows to the sliding contact surface between the slide block 7 and the track frame 4 after being slowed down by the sponge cover, reducing the sliding friction between them. If it is necessary to adjust the lubricating oil outflow rate, air can be injected into the oil reservoir 14 through the air inlet 21, pushing the piston 20 to move and change the oil pressure in the oil reservoir 14, thereby controlling the lubricating oil outflow rate. Throughout the process, all components work together to ensure stable operation of the paper tube replacement, meet the processing requirements of the coating material, and facilitate the position adjustment and lubrication maintenance of the ash-adhesive paper tube 13.
