Description

Technical Field

[0001] This invention belongs to the field of paper tube production technology, and in particular relates to an overflow glue device for paper tube production. Background Technology

[0002] As a core component in packaging, printing, and other fields, the quality of the gluing process in paper tube production directly affects the product's sealing performance and lifespan. When a gluing machine continuously applies glue to paper tubes through a glue tank, improper glue control or fluctuations in the paper tube's running speed can easily cause glue to overflow and adhere to the upper and lower surfaces of the paper tube. If the overflow is not cleaned up in time, it will not only waste glue but also contaminate the equipment, affect subsequent processes (such as drying or winding), and even cause the paper tube to stick together, deform, and reduce the finished product's pass rate.

[0003] Existing technologies for handling excess glue on paper tubes still have the following drawbacks: Traditional glue cleaning devices mostly use fixed scrapers to directly remove the glue, but when the scraper comes into contact with the paper tube, the glue is prone to splashing due to its stickiness, causing secondary pollution. At the same time, the glue layer is easily left on the surface of the paper tube due to friction when the scraper is scraping, which is especially unsuitable for paper tubes with uneven thickness, resulting in problems such as incomplete scraping, easy accumulation of glue, and inconvenient cleaning. Secondly, during the glue recovery process, the glue is easy to accumulate in the scraping mechanism or the guide channel, and cannot be efficiently returned to the glue tank of the glue coater for reuse, resulting in glue waste.

[0004] To address this issue, we provide an overflow adhesive device for paper tube production to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an overflow adhesive device for paper tube production. By combining a scraping mechanism and a pretreatment mechanism, it solves the problems of low overflow adhesive removal efficiency and poor effect in existing paper tube production overflow adhesive devices.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0007] This invention relates to an overflow adhesive device for paper tube production, comprising an adhesive applicator and a paper tube conveyor belt. An mounting plate is fixedly connected to one side of the adhesive applicator, and a housing is fixedly connected to one side of the mounting plate via an mounting rod. A scraping mechanism is provided inside the housing, comprising a scraping cylinder rotatably connected to one side of the housing via a bearing seat, a scraping plate fixedly connected to the surface of the scraping cylinder, a spiral conveying roller rotatably connected to the inner wall of the scraping cylinder via a bearing seat, and a worm gear rotatably connected to the inner cavity of the housing via a bearing seat. A pretreatment mechanism is provided on one side of the housing, comprising a baffle fixedly connected to one side of the housing and a cleaning plate disposed on one side of the scraping plate.

[0008] The present invention is further configured such that a drive motor is fixedly connected to one side of the mounting plate, and a first synchronous belt is connected between the output shaft of the drive motor and the worm gear. The drive motor transmits power to the worm gear through the first synchronous belt, providing a power source for the rotation of the scraper cylinder. The structure is compact and the transmission is reliable.

[0009] The invention is further configured such that a first gear is fixedly connected to the surface of the scraper cylinder, the scraper cylinder includes an upper cylinder and a lower cylinder, the upper cylinder and the lower cylinder are respectively located on the upper and lower sides of the paper tube belt, the upper cylinder and the lower cylinder are arranged in parallel, the spacing is adapted to the thickness of the paper tube belt, the first gear fixedly connected to the surface of the upper cylinder and the lower cylinder meshes with each other, so that when the worm drives the upper cylinder to rotate through the worm wheel to rotate, the upper cylinder drives the lower cylinder to rotate through the first gear, and through the opposite gear meshing design, the upper cylinder and the lower cylinder rotate in opposite directions, so that the opening direction of the scraper plate on the surface of the upper cylinder and the lower cylinder is facing the paper tube belt conveying direction, realizing synchronous reverse scraping of the glue overflow on the upper and lower surfaces of the paper tube belt, improving the glue scraping efficiency and effect.

[0010] The invention is further configured such that a worm wheel meshes with the surface of the worm, and the axis of the worm wheel is fixedly connected to the surface of the upper cylinder. The rotation of the worm drives the worm wheel, thereby driving the upper cylinder to rotate. The transmission is smooth and has a self-locking function to prevent the scraper cylinder from reversing.

[0011] The invention is further configured such that a feeding groove is formed on the surface of the scraper cylinder, the feeding groove is correspondingly arranged with the scraper plate, the inner cavity of the feeding groove is rotatably connected to a rotating shaft through a bearing seat, a sealing plate is fixedly connected to the surface of the rotating shaft, one end of the rotating shaft passes through to the outside of the scraper cylinder and is fixedly connected to a second gear, the adhesive scraped off by the scraper plate is introduced into the scraper cylinder through the feeding groove, the sealing plate closes the feeding groove when not in the working position to prevent adhesive leakage and splashing, and the second gear is used to drive the sealing plate to rotate.

[0012] The invention is further configured such that one end of the spiral conveying roller extends through to the outside of the scraper cylinder and is fixedly connected to a third gear, the surface of the third gear meshes with a fourth gear, one side of the fourth gear is fixedly connected to the inner cavity of the machine housing via a support rod, and one side of the fourth gear is fixedly connected to an arc-shaped rack. The position of the fourth gear is fixed. When the scraper cylinder rotates and drives the spiral conveying roller to revolve, the third gear meshes with the fixed fourth gear, forcing the spiral conveying roller to rotate and conveying the adhesive collected in the scraper cylinder to one end. The arc-shaped rack is correspondingly set at the scraper station. When the second gear rotates with the scraper cylinder to the scraper station, it meshes with the arc-shaped rack, driving the rotating shaft to rotate 90 degrees, opening the sealing plate, so that the feed trough at the scraper station is in an open state, and the scraped adhesive can enter the scraper cylinder. When the scraper plate at the scraper station continues to rotate a certain angle, it meshes with another arc-shaped rack, driving the rotating shaft to rotate 90 degrees a second time, closing the sealing plate.

[0013] The invention is further configured such that a funnel is fixedly connected to one end of the scraper cylinder, there are four machine housings, and six scraper cylinders are rotatably connected to one side of each machine housing. Adjacent machine housings are staggered, and a second synchronous belt is connected between two worm gears located on the same end face. The funnel is used to concentrate and guide the glue in the scraper cylinder to the glue tank of the coating machine. The six scraper cylinders are evenly distributed along the width of the paper tube to ensure that the entire surface of the paper tube is covered, avoiding missed scraping. The staggered arrangement shortens the overall length of the device, reduces space occupation, and improves integration. The funnel of the upper cylinder is longer than the funnel of the lower cylinder to prevent the glue recovered from the upper layer from dripping and contaminating the lower scraper cylinder. The collected glue flows directly back to the glue tank of the coating machine through the funnel, realizing recycling.

[0014] The invention is further configured such that one end of the worm gear extends through the inner cavity of the baffle and is fixedly connected to a first bevel gear, a second bevel gear meshes with the surface of the first bevel gear, a reciprocating screw is fixedly connected to the shaft of the second bevel gear, a threaded sleeve is sleeved on the surface of the reciprocating screw, and a limit rod is fixedly connected to the surface of the threaded sleeve. The rotation of the worm gear changes the transmission direction through the bevel gear set, drives the reciprocating screw to rotate, and drives the threaded sleeve and the cleaning plate to reciprocate along the surface of the baffle, automatically cleaning the adhesive accumulated on the baffle and preventing it from solidifying and affecting the material blocking effect.

[0015] The invention is further configured such that one end of the limiting rod extends through to the outside of the baffle and is fixedly connected to one side of the cleaning plate, and a limiting groove adapted to the limiting rod is provided on one side of the baffle. The top and bottom of the baffle are provided with inclined surfaces. The limiting groove restricts the limiting rod to move only in the horizontal direction, ensuring that the cleaning plate moves smoothly back and forth and that the cleaning plate moves in a straight line without deviation. The inclined surface design facilitates the guidance of the cleaned adhesive to both sides, allowing it to flow back to the adhesive tank by gravity.

[0016] The present invention is further configured such that a control panel is fixedly connected to one side of the glue applicator.

[0017] The present invention has the following beneficial effects.

[0018] 1. This invention drives the cleaning plate to reciprocate through worm gear transmission and bevel gear set, which can automatically remove the glue accumulated on the surface of the baffle, avoid glue accumulation affecting equipment operation, and perform preliminary treatment of overflow glue. The upper and lower cylinders achieve reverse rotation through the reverse meshing of the first gear, and the opening direction of the scraper plates on their surfaces is facing the paper tube belt conveying direction, forming synchronous reverse scraping of the upper and lower surfaces of the paper tube belt, avoiding unidirectional glue residue, and significantly improving the glue scraping efficiency and thoroughness.

[0019] 2. This invention prevents glue from splashing when the feed groove on the surface of the scraper cylinder is closed by a sealing plate. When the scraper cylinder rotates to the working position, the second gear meshes with the arc-shaped rack to drive the sealing plate to open, allowing only the scraped glue to enter the scraper cylinder, thus achieving both splash prevention and precise feeding. The spiral conveying roller rotates through the meshing of the third gear and the fixed fourth gear, directionally conveying the glue in the scraper cylinder to the funnel. The design of the upper funnel being longer than the lower funnel prevents the upper layer of glue from dripping and contaminating the lower layer. Finally, the glue flows directly back to the glue tank of the glue applicator through the funnel, shortening the recycling path, achieving efficient recycling of glue, and reducing waste.

[0020] 3. This invention uses four chassis arranged in a staggered manner along the width of the paper tube, with each chassis equipped with six scraper cylinders. This not only covers the entire surface of the paper tube to achieve scraping without dead angles, but also shortens the overall length of the device through the staggered design, improving the space utilization of the production line. The two worm gears on the same end face are linked by a second synchronous belt to ensure that the upper and lower cylinders rotate at the same speed. The drive motor drives the worm gears through a first synchronous belt. The transmission structure is simple, compact, and highly reliable, and adapts to the needs of high-speed continuous production.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0034] Please see Figures 1-9 This invention relates to an overflow glue device for paper tube production, comprising a glue applicator 1 and a paper tube belt 2. A mounting plate 3 is fixedly connected to one side of the glue applicator 1, and a housing 4 is fixedly connected to one side of the mounting plate 3 via a mounting rod. A scraping mechanism is provided inside the housing 4, which includes a scraping cylinder 5 rotatably connected to one side of the housing 4 via a bearing seat, a scraping plate 6 fixedly connected to the surface of the scraping cylinder 5, a spiral conveying roller 7 rotatably connected to the inner wall of the scraping cylinder 5 via a bearing seat, and a worm gear 8 rotatably connected to the inner cavity of the housing 4 via a bearing seat. A drive motor 11 is fixedly connected to one side of the mounting plate 3, and a first synchronous belt 12 is connected between the output shaft of the drive motor 11 and the worm gear 8. A first gear 13 is fixedly connected to the surface of the scraping cylinder 5. The scraping cylinder 5 includes an upper cylinder 51 and a lower cylinder 52, which are located on the upper and lower sides of the paper tube belt 2, respectively. A worm wheel 14 meshes with the surface of the worm gear 8, and the shaft of the worm wheel 14 is fixedly connected to the surface of the upper cylinder 51.

[0035] Further details: The drive motor 11 transmits power to the worm gear 8 via the first synchronous belt 12, providing a power source for the rotation of the scraper cylinder 5. It features a compact structure and reliable transmission. The upper cylinder 51 and lower cylinder 52 are arranged parallel to each other, with a spacing adapted to the thickness of the paper tube 2. The first gear 13, fixedly connected to the surfaces of the upper cylinder 51 and lower cylinder 52, meshes with each other. This facilitates the rotation of the upper cylinder 51 via the first gear 13 when the worm gear 8 drives the upper cylinder 51 to rotate through the worm wheel 14. Furthermore, the reverse gear meshing design ensures that the upper cylinder 51 and lower cylinder 52 rotate in opposite directions, resulting in the scraper plates 6 on the surfaces of both cylinders facing the conveying direction of the paper tube 2. This achieves synchronous reverse scraping of excess glue from the upper and lower surfaces of the paper tube, improving scraping efficiency and effectiveness. The rotation of the worm gear 8 drives the worm wheel 14, which in turn drives the upper cylinder 51 to rotate. The transmission is smooth and has a self-locking function to prevent the scraper cylinder 5 from reversing. Example 2

[0036] Please see Figures 1-9 Based on embodiment 1, a feed groove 15 is provided on the surface of the scraper cylinder 5. The feed groove 15 is correspondingly arranged with the scraper plate 6. The inner cavity of the feed groove 15 is rotatably connected to the rotating shaft 16 through the bearing seat. A sealing plate 17 is fixedly connected to the surface of the rotating shaft 16. One end of the rotating shaft 16 passes through to the outside of the scraper cylinder 5 and is fixedly connected to the second gear 18. One end of the spiral conveying roller 7 passes through to the outside of the scraper cylinder 5 and is fixedly connected to the third gear 19. A fourth gear 20 meshes on the surface of the third gear 19. One side of the fourth gear 20 is fixedly connected to the inner cavity of the machine box 4 through the support rod. An arc-shaped rack 21 is fixedly connected to one side of the fourth gear 20. A funnel 22 is fixedly connected to one end of the scraper cylinder 5. There are four machine boxes 4, and six scraper cylinders 5 are rotatably connected to one side of each machine box 4. The two adjacent machine boxes 4 are staggered. A second synchronous belt 23 is connected between the two worm gears 8 located on the same end face.

[0037] Further details: The adhesive scraped by the scraper blade 6 is fed into the scraper cylinder 5 through the feed trough 15. When not in the working position, the sealing plate 17 closes the feed trough 15 to prevent adhesive leakage and splashing. The second gear 18 drives the sealing plate 17 to rotate, and the fourth gear 20 is fixed in position. When the scraper cylinder 5 rotates and drives the spiral conveyor roller 7 to revolve, the third gear 19 meshes with the fixed fourth gear 20, forcing the spiral conveyor roller 7 to rotate and conveying the adhesive collected in the scraper cylinder 5 to one end. The arc-shaped rack 21 is correspondingly set at the scraping position. When the second gear 18 rotates with the scraper cylinder 5 to the scraping position, it meshes with the arc-shaped rack 21, driving the rotating shaft 16 to rotate 90 degrees, opening the sealing plate 17, so that the feed trough 15 at the scraping position is in an open state. The scraped adhesive can then enter the scraper cylinder 5. When the scraper plate 6 at the scraper station continues to rotate at a certain angle, it meshes with another arc-shaped rack 21, driving the rotating shaft 16 to rotate 90 degrees again, closing the sealing plate 17. The funnel 22 is used to concentrate and guide the adhesive in the scraper cylinder 5 to the glue tank of the glue coater 1. The six scraper cylinders 5 are evenly distributed along the width direction of the paper tube 2 to ensure that the entire surface of the paper tube 2 is covered, avoiding missed scraping. The staggered arrangement shortens the overall length of the device, reduces space occupation, and improves integration. The funnel 22 of the upper cylinder 51 is longer than the funnel 22 of the lower cylinder 52 to prevent the adhesive recovered from the upper layer from dripping and contaminating the lower scraper cylinder 5. The collected adhesive flows directly back to the glue tank of the glue coater 1 through the funnel 22 to achieve recycling. Example 3

[0038] Please see Figures 1-9 Based on Embodiments 1 and 2, a pretreatment mechanism is provided on one side of the chassis 4. The pretreatment mechanism includes a baffle 9 fixedly connected to one side of the chassis 4, a cleaning plate 10 provided on one side of the scraper 6, a worm gear 8 extending through the inner cavity of the baffle 9 and fixedly connected to a first bevel gear 24, a second bevel gear 25 meshing on the surface of the first bevel gear 24, a reciprocating screw 26 fixedly connected at the shaft of the second bevel gear 25, a threaded sleeve 27 sleeved on the surface of the reciprocating screw 26, a limiting rod 28 fixedly connected to the surface of the threaded sleeve 27, one end of the limiting rod 28 extending through the outside of the baffle 9 and fixedly connected to one side of the cleaning plate 10, a limiting groove 29 adapted to the limiting rod 28 being provided on one side of the baffle 9, and inclined surfaces 31 being provided at the top and bottom of the baffle 9, and a control panel 30 fixedly connected to one side of the glue applicator 1.

[0039] Further details: The worm gear 8 rotates and changes the transmission direction through the bevel gear set, driving the reciprocating screw 26 to rotate. This causes the screw sleeve 27 and the cleaning plate 10 to reciprocate along the surface of the baffle 9, automatically cleaning the adhesive accumulated on the baffle 9 and preventing it from solidifying and affecting the material blocking effect. The limiting groove 29 restricts the limiting rod 28 to move only in the horizontal direction, ensuring that the cleaning plate 10 moves smoothly back and forth and that the linear movement of the cleaning plate 10 is not skewed. The inclined surface 31 is designed to guide the cleaned adhesive to both sides and allow it to flow back to the adhesive tank by gravity. The control panel 30 integrates control functions, making it easy to operate and adjust the equipment operating parameters.

[0040] The working principle of this invention is as follows: the glue applicator 1 is fixed at the glue applicator station of the production line, the paper tube 2 passes through the glue tank of the glue applicator 1 and is conveyed at a constant speed by the drive device (existing technology). When the paper tube 2 is being glued on the glue applicator 1, if glue overflows, the overflowing glue adheres to the upper and lower surfaces of the paper tube 2 and enters the working area of ​​the scraping mechanism. The baffle 9 performs preliminary scraping of the overflowing glue on the upper and lower surfaces of the paper tube 2.

[0041] When the drive motor 11 starts, the output shaft of the drive motor 11 drives the worm 8 to rotate through the first synchronous belt 12. When the worm 8 rotates, the worm 8 at one end drives the first bevel gear 24 to rotate. The first bevel gear 24 drives the reciprocating screw 26 to rotate through the second bevel gear 25. The reciprocating screw 26 drives the threaded sleeve 27 sleeved on it to move back and forth along the axial direction. The threaded sleeve 27 drives the cleaning plate 10 to move back and forth synchronously through the limit rod 28, scraping the glue accumulated on the surface of the baffle 9 to the two inclined surfaces 31, and then falling into the glue tank under the action of gravity, so as to avoid the glue accumulation on the surface of the baffle 9 from affecting the operation of the device.

[0042] On the other hand, the worm gear 8 drives the upper cylinder 51 to rotate through the worm wheel 14. The lower cylinder 52 meshes with the upper cylinder 51 through the first gear 13 and rotates counterclockwise with the upper cylinder 51. The scraper plates 6 on the surface of the upper and lower scraper cylinders 5 rotate accordingly to scrape off the excess glue on the upper and lower surfaces of the paper tape. When the scraper cylinder 5 rotates to the scraping station, the second gear 18 meshes with the fixed arc-shaped rack 21. After the sealing plate 17 rotates 90 degrees, the sealing plate 17 opens, and the scraped glue enters the scraper cylinder 5 through the feed trough 15 to further scrape off the excess glue on the upper and lower surfaces of the paper tube tape 2. When the scraper plate 6 at the scraping station continues to rotate a certain angle, it meshes with another arc-shaped rack 21, driving the rotating shaft 16 to rotate 90 degrees a second time and closing the sealing plate 17. When the sealing plate 17 is not in the working position, it closes the feed trough 15 to prevent glue leakage and splashing.

[0043] Simultaneously, the spiral conveyor roller 7 rotates under the meshing action of the third gear 19 and the fixed fourth gear 20, pushing the adhesive to the funnel 22. The funnel 22 of the upper cylinder 51 is longer than the funnel 22 of the lower cylinder 52, preventing the adhesive recovered from the upper layer from dripping and contaminating the lower scraper cylinder 5, and returning it to the adhesive tank, thus realizing the recycling of the adhesive. Multiple housings 4 are arranged in a staggered manner, with six scraper cylinders 5 installed in each housing 4 to ensure that there are no dead angles in the scraping of adhesive. The worm gear 8 on the same side is linked by the second synchronous belt 23 to ensure synchronous operation.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
