Description

Technical Field

[0001] This invention belongs to the field of paper tube production technology, and in particular relates to a fully automatic rolling and forming equipment for multi-layer composite high-strength paper tubes. Background Technology

[0002] Multi-layer composite high-strength paper tubes, as a lightweight, high-strength, and recyclable new type of composite material product, are widely used in packaging containers (such as industrial paper tubes and paper drums), mechanical transmission rollers, building support structures, and other fields. They are formed by winding and laminating multiple layers of paper, and the interlayer bonding strength is a core indicator determining product performance. The gluing process before winding directly determines the quality of the interlayer adhesion.

[0003] Existing paper tube coating equipment mostly uses a fixed coating roller structure, which has the following shortcomings: First, it is difficult to guarantee the uniformity of coating, especially when the paper thickness or tension fluctuates, which can easily lead to missed coating or uneven coating thickness. At the same time, it cannot adaptively adjust the coating pressure according to the paper thickness, which can easily lead to missed coating on thin paper and excessive or uneven coating on thick paper, affecting the interlayer bonding strength. Second, glue replenishment depends on manual observation of the liquid level. If the glue level drops and the glue is not replenished in time, it can easily cause a supply interruption. If the liquid level is too high, it may overflow, resulting in fluctuations in the amount of glue coated. Third, the glue in the glue box is exposed to the air for a long time, which can easily cause oxidation or solidification and clumping due to moisture evaporation. Frequent machine shutdowns are required for cleaning, which seriously affects production efficiency.

[0004] To address these issues, we provide a fully automated rolling and forming equipment for multi-layer composite high-strength paper tubes. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic winding and forming equipment for multi-layer composite high-strength paper tubes. By coordinating an adaptive gluing mechanism and a glue-adding mechanism, the invention solves the problems of uneven glue application and easy glue solidification in existing fully automatic winding and forming equipment for multi-layer composite high-strength paper tubes.

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

[0007] This invention relates to a fully automatic winding and forming device for multi-layer composite high-strength paper tubes, comprising a paper tube machine body, a glue coating box fixedly connected to one side of the paper tube machine body, and a drive motor fixedly connected to one side of the glue coating box; an adaptive glue coating mechanism is provided in the inner cavity of the glue coating box, the adaptive glue coating mechanism including a telescopic rod fixedly connected to the top of the inner cavity of the glue coating box, a first spring sleeved on the surface of the telescopic rod, a guide roller fixedly connected to the output shaft of the telescopic rod, and a glue coating roller rotatably connected to the inner cavity of the glue coating box through a bearing seat; the inner cavity of the glue coating box is also provided with a glue filling mechanism, the glue filling mechanism including a fixed cylinder rotatably connected to the inner cavity of the glue coating box through a bearing seat, a brush disposed on the surface of the fixed cylinder, and a glue box disposed at the bottom of the inner cavity of the glue coating box.

[0008] The invention is further configured such that the output shaft of the drive motor is connected to one end of the fixed cylinder via a synchronous belt, a first gear is fixedly connected to the surface of the fixed cylinder, a second gear meshes with the surface of the first gear, and the shaft of the second gear is fixedly connected to one end of the coating roller. Both the coating roller and one end of the fixed cylinder extend to the outside of the coating box to accommodate the synchronous belt. The drive motor drives the fixed cylinder to rotate via the synchronous belt, and the fixed cylinder drives the coating roller to rotate synchronously in the opposite direction via the meshing of the first gear and the second gear. This ensures that the contact linear speed between the coating roller and the paper matches the conveying speed of the paper tube machine body, and at the same time, the uniformity of coating is enhanced by the reverse rotation.

[0009] The invention is further configured such that one end of the first spring is fixedly connected to one side of the glue-coating box, and the other end of the first spring is fixedly connected to one side of the guide roller. There are two guide rollers, and the glue-coating roller is located between the two guide rollers. The two guide rollers are symmetrically distributed in the vertical direction. The glue-coating roller is located in the V-shaped gap formed between the two guide rollers. The elastic force of the first spring pushes the guide roller to squeeze towards the glue-coating roller. When the paper is conveyed to the glue-coating box by the paper tube machine body, it is clamped and pressed tightly against the surface of the glue-coating roller by the two guide rollers, eliminating the gap between the paper and the glue-coating roller, ensuring that the glue on the surface of the glue-coating roller is completely transferred to the paper, and avoiding missed coating or uneven coating thickness.

[0010] The invention is further configured such that a fixed rod is fixedly connected to one side of the brush, a drive wheel is fixedly connected to one end of the fixed rod, a second spring is sleeved on the surface of the fixed rod, a drive roller is provided in the inner cavity of the fixed cylinder, one end of the second spring is fixedly connected to one side of the drive wheel, and the other end of the second spring is fixedly connected to the inner cavity of the fixed cylinder, and the drive roller moves up and down with the rise and fall of the float.

[0011] The invention is further configured such that a float plate is provided inside the glue box, a support rod is fixedly connected to the top of the float plate, a support plate is fixedly connected to the top of the support rod, and a baffle plate is fixedly connected to one side of the support plate. When the glue level in the glue box drops, the float plate sinks due to reduced buoyancy. The support rod and support plate drive the baffle plate to move downward. After the outlet pipe is unobstructed, the glue in the hopper flows into the glue box under the action of gravity. When the glue level in the glue box rises back to the set height, the float plate rises, the baffle plate resets upward and re-abuts the outlet pipe, stopping the glue replenishment. This achieves automatic control of the glue quantity, avoids glue overflow or supply interruption, and keeps the glue in the glue box within a certain range to ensure the amount of glue absorbed by the brush.

[0012] The invention is further configured such that a material box is fixedly connected to the top of the glue application box, a feed pipe is connected to one side of the material box, and a scale observation window is provided on the front of the material box. The material box is used to store glue, and the scale observation window allows the operator to observe the remaining amount of glue in real time, replenish glue in time, and avoid glue application interruption due to lack of glue.

[0013] The present invention is further configured such that a worm is fixedly connected to the output shaft of the drive motor, a worm gear ring meshes with the surface of the worm, a mounting plate is fixedly connected to the surface of the worm gear ring, and a rotating shaft is rotatably connected to the inner wall of the mounting plate through a bearing seat.

[0014] The invention is further configured such that a third gear is fixedly connected to one end of the rotating shaft, a toothed ring meshes with the surface of the third gear, the toothed ring is fixedly connected to the top of the glue box, a first bevel gear is fixedly connected to the other end of the rotating shaft, a second bevel gear meshes with the surface of the first bevel gear, a fan blade is fixedly connected to the shaft center of the second bevel gear, a protective cover is fitted on the surface of the rotating shaft, a drive motor drives a worm gear ring to rotate through a worm, the worm gear ring drives the rotating shaft to revolve through a mounting plate, and the worm gear ring drives the rotating shaft to rotate on its own axis through the meshing of the third gear and the toothed ring, the rotating shaft drives the fan blades (six fan blades) to rotate at high speed through the meshing of the first bevel gear and the second bevel gear, driving the glue in the glue box to circulate, maintaining the activity of the glue, breaking the contact interface between the glue and the air, solving the problem that the glue in the glue box cavity has a large contact area with the air, which makes it easy for it to solidify quickly, and the protective cover isolates the first bevel gear, the second bevel gear and the glue, preventing the glue from seeping into the meshing gap and causing jamming.

[0015] The invention is further configured such that the inner cavity of the toothed ring is provided with a sliding groove, and a supporting slider is slidably connected to the inner cavity of the sliding groove. The supporting slider is fixedly connected to the inner cavity of the glue box through an L-shaped plate. The supporting slider restricts the toothed ring to rotate only around the central axis, so as to avoid the toothed ring from shifting due to the glue pressure in the glue box or the vibration of the fan blade, and to ensure the meshing stability of the third gear and the toothed ring.

[0016] The invention is further configured such that a protective door is hinged to one side of the glue coating box, and through slots are provided on both sides of the glue coating box. When the protective door is closed, the glue coating box is sealed to prevent glue leakage. The through slots allow paper to pass through the glue coating box, and their size design ensures smooth paper feeding and avoids paper jams.

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

[0018] 1. This invention, through the cooperation of a telescopic rod, a first spring, and a guide roller, can automatically adjust the distance between the guide roller and the coating roller according to the paper thickness, ensuring that the paper adheres tightly to the surface of the coating roller, eliminating gaps, and avoiding missed coating or uneven coating thickness. At the same time, the coating roller and the fixed cylinder rotate in opposite directions, enhancing the uniformity of coating and significantly improving the interlayer bonding strength. In addition, through the floating drive brush mechanism design, the drive roller moves up and down with changes in liquid level, and the extension of the brush is dynamically adjusted through the cooperation of the drive wheel and the second spring, so that the contact area between the brush and the glue remains constant under different glue liquid levels, thereby ensuring a stable amount of glue transferred to the coating roller and avoiding fluctuations in the amount of glue coated.

[0019] 2. The glue-adding mechanism of this invention achieves automatic monitoring and replenishment of glue level through the linkage design of float plate, support rod, baffle plate and liquid outlet pipe. When the liquid level drops, the baffle plate moves down to open glue replenishment. When the liquid level rises, it automatically closes to prevent glue overflow or lack of glue, ensuring stable glue absorption by the brush, thereby maintaining a constant glue application amount and improving product consistency.

[0020] 3. This invention uses a drive motor to drive the brush and the glue roller to rotate synchronously via a worm gear, worm wheel ring, rotating shaft and gear set, and drives the fan blade to rotate at high speed, which promotes the circulation of glue in the glue box, breaks the contact interface between glue and air, effectively prevents glue from solidifying and ensures continuous production efficiency.

[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

[0032] 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.

[0033] Example 1

[0034] Please see Figures 1-8This invention relates to a fully automatic winding and forming equipment for multi-layer composite high-strength paper tubes, comprising a paper tube machine body 1, a glue coating box 2 fixedly connected to one side of the paper tube machine body 1, and a drive motor 3 fixedly connected to one side of the glue coating box 2; an adaptive glue coating mechanism is provided in the inner cavity of the glue coating box 2, the adaptive glue coating mechanism including a telescopic rod 4 fixedly connected to the top of the inner cavity of the glue coating box 2, a first spring 5 sleeved on the surface of the telescopic rod 4, a guide roller 6 fixedly connected to the output shaft of the telescopic rod 4, and a glue coating roller 7 rotatably connected to the inner cavity of the glue coating box 2 through a bearing seat; the output shaft of the drive motor 3 is connected to one end of a fixed cylinder 8 via a synchronous belt; a first gear 11 is fixedly connected to the surface of the fixed cylinder 8, a second gear 12 meshes with the surface of the first gear 11, the shaft of the second gear 12 is fixedly connected to one end of the glue coating roller 7, one end of the first spring 5 is fixedly connected to one side of the glue coating box 2, and the other end of the first spring 5 is fixedly connected to one side of the guide roller 6; there are two guide rollers 6, and the glue coating roller 7 is located between the two guide rollers 6.

[0035] Further details: Both the coating roller 7 and the fixed cylinder 8 extend to the outside of the coating box 2 to accommodate the synchronous belt (the synchronous belt has friction strips on its inner side to prevent slippage, which is existing technology). The drive motor 3 drives the fixed cylinder 8 to rotate via the synchronous belt. The fixed cylinder 8 drives the coating roller 7 to rotate synchronously in the opposite direction through the meshing of the first gear 11 and the second gear 12, ensuring that the contact linear speed between the coating roller 7 and the paper matches the conveying speed of the paper tube machine body 1. At the same time, the reverse rotation enhances the uniformity of coating. There are two guide rollers 6, which are symmetrically distributed in the vertical direction. The coating roller 7 is located in the V-shaped gap formed between the two guide rollers 6. The elastic force of the first spring 5 pushes the guide rollers 6 to squeeze towards the coating roller 7. When the paper is conveyed to the coating box 2 by the paper tube machine body 1, it is clamped and pressed tightly against the surface of the coating roller 7 by the two guide rollers 6, eliminating the gap between the paper and the coating roller 7, ensuring that the glue on the surface of the coating roller 7 is completely transferred to the paper, and avoiding missed coating or uneven coating thickness.

[0036] Example 2

[0037] Please see Figures 1-8Based on Embodiment 1, the inner cavity of the glue coating box 2 is also provided with a glue-filling mechanism. The glue-filling mechanism includes a fixed cylinder 8 rotatably connected to the inner cavity of the glue coating box 2 via a bearing seat, a brush 9 disposed on the surface of the fixed cylinder 8, a glue box 10 disposed at the bottom of the inner cavity of the glue coating box 2, a fixed rod 13 fixedly connected to one side of the brush 9, a drive wheel 14 fixedly connected to one end of the fixed rod 13, a second spring 15 sleeved on the surface of the fixed rod 13, a drive roller 16 disposed in the inner cavity of the fixed cylinder 8, a float 17 disposed in the inner cavity of the glue box 10, a support rod 18 fixedly connected to the top of the float 17, a support plate 19 fixedly connected to the top of the support rod 18, a baffle plate 20 fixedly connected to one side of the support plate 19, a material box 21 fixedly connected to the top of the glue coating box 2, a feed pipe 22 connected to one side of the material box 21, and a scale observation window 23 disposed on the front of the material box 21.

[0038] Further supplement: One end of the second spring 15 is fixedly connected to one side of the drive wheel 14, and the other end of the second spring 15 is fixedly connected to the inner cavity of the fixed cylinder 8. The drive roller 16 moves up and down with the rise and fall of the float 17. When the glue level in the glue box 10 decreases, the drive roller 16 moves down, contacts the drive wheel 14 and presses down, compressing the second spring 15 and causing the fixed rod 13 to extend outward, so that the contact area between the brush 9 and the glue in the inner cavity of the glue box 10 remains constant within a certain range. When the fixed cylinder 8 drives the fixed rod 13 to rotate from the bottom to the top, since the drive roller 16 is not in contact with the drive wheel 14 at this time, the fixed rod 13 returns to its original position under the action of the second spring 15. At this time, the contact time and area between the brush 9 and the bottom of the glue coating roller 7 remain constant, so that the amount of glue coated by the brush 9 on the surface of the glue coating roller 7 remains constant. Through this dynamic adjustment The system ensures that the contact area between the brush 9 and the glue remains constant at different liquid levels, avoiding fluctuations in the amount of glue applied. When the glue level in the glue box 10 drops, the float 17 sinks due to reduced buoyancy. This causes the baffle 20 to move downwards via the support rod 18 and support plate 19. After the outlet pipe is unobstructed, the glue in the material box 21 flows into the glue box 10 under gravity. When the glue level in the glue box 10 rises back to the set height, the float 17 floats up, and the baffle 20 resets upwards and re-engages with the outlet pipe, stopping the glue replenishment. This achieves automatic control of the glue amount, preventing glue overflow or supply interruption. At the same time, it keeps the glue in the glue box 10 within a certain range, ensuring the amount of glue absorbed by the brush 9. The material box 21 is used to store glue, and the scale observation window 23 allows operators to observe the remaining glue amount in real time and replenish glue in a timely manner, avoiding glue application interruptions due to insufficient glue.

[0039] Example 3

[0040] Please see Figures 1-8Based on Embodiments 1 and 2, a worm gear 24 is fixedly connected to the output shaft of the drive motor 3. A worm wheel ring 25 meshes with the surface of the worm gear 24. A mounting plate 26 is fixedly connected to the surface of the worm wheel ring 25. A rotating shaft 27 is rotatably connected to the inner wall of the mounting plate 26 via a bearing seat. A third gear 28 is fixedly connected to one end of the rotating shaft 27. A toothed ring 29 meshes with the surface of the third gear 28. The toothed ring 29 is fixedly connected to the top of the glue box 10. A first bevel gear 30 is fixedly connected to the other end of the rotating shaft 27. A second bevel gear 31 meshes with the surface of the first bevel gear 30. A fan blade 32 is fixedly connected to the shaft center of the second bevel gear 31. A protective cover 33 is sleeved on the surface of the rotating shaft 27. A sliding groove 34 is provided in the inner cavity of the toothed ring 29. A support slider 35 is slidably connected in the inner cavity of the sliding groove 34. The support slider 35 is fixedly connected to the inner cavity of the glue coating box 2 via an L-shaped plate. A protective door 36 is hinged to one side of the glue coating box 2. Through slots 37 are provided on both sides of the glue coating box 2.

[0041] Further details: The drive motor 3 drives the worm gear ring 25 to rotate via the worm 24. The worm gear ring 25 drives the rotating shaft 27 to revolve via the mounting plate 26. Simultaneously, the worm gear ring 25 drives the rotating shaft 27 to rotate via the meshing of the third gear 28 and the toothed ring 29. The rotating shaft 27 drives the fan blades 32 (there are six fan blades) to rotate at high speed via the meshing of the first bevel gear 30 and the second bevel gear 31. This causes the glue in the glue box 10 to circulate, maintaining the glue's activity and disrupting the contact interface between the glue and air, thus solving the problem of the large contact area between the glue and air inside the glue box 10 causing its degradation. To address the issue of rapid solidification, the protective cover 33 isolates the first bevel gear 30 and the second bevel gear 31 from the glue, preventing the glue from seeping into the meshing gap and causing jamming. The support slider 35 restricts the toothed ring 29 to rotate only around the central axis, preventing the toothed ring 29 from shifting due to glue pressure in the glue box 10 or vibration of the fan blade 32, thus ensuring the meshing stability of the third gear 28 and the toothed ring 29. When the protective door 36 is closed, it ensures the airtightness of the glue coating box 2 and prevents glue leakage. The through slot 37 allows paper to pass through the glue coating box 2, and its size design ensures smooth paper feeding and avoids paper jams.

[0042] The working principle of this invention is as follows: the paper to be coated is conveyed to the paper tube machine body 1 through the coating box 2. The paper first enters the V-shaped gap formed by the two guide rollers 6 and the coating roller 7. The first spring 5 pushes the guide roller 6 to squeeze the paper so that it is in close contact with the surface of the coating roller 7.

[0043] After the drive motor 3 starts, it drives the fixed cylinder 8 to rotate via the synchronous belt. The brush 9 on the surface of the fixed cylinder 8 rotates synchronously and comes into contact with the glue in the glue box 10, applying the glue to the surface of the glue roller 7. During the rotation of the fixed cylinder 8, the glue roller 7 is driven to rotate via the first gear 11 and the second gear 12. The uniformity of glue application is enhanced by the reverse rotation.

[0044] The drive roller 16 moves up and down with the float 17. When the glue level in the glue box 10 decreases, the drive roller 16 moves down, contacts the drive wheel 14 and presses down, compressing the second spring 15 and causing the fixing rod 13 to extend outward. This keeps the contact area between the brush 9 and the glue in the inner cavity of the glue box 10 constant within a certain range. When the fixing cylinder 8 drives the fixing rod 13 to rotate from the bottom to the top, the drive roller 16 does not contact the drive wheel 14 at this time. The fixing rod 13 returns to its original position under the action of the second spring 15. At this time, the contact time and area between the brush 9 and the bottom of the glue coating roller 7 remain constant, thus keeping the amount of glue coated on the surface of the glue coating roller 7 constant. Through this dynamic adjustment, the contact area between the brush 9 and the glue is kept constant at different liquid levels, avoiding fluctuations in the amount of glue coated.

[0045] At the same time, the drive motor 3 drives the worm gear ring 25 to rotate through the worm 24. The worm gear ring 25 drives the rotating shaft 27 to revolve through the mounting plate 26. The rotating shaft 27 rotates by meshing with the toothed ring 29 through the third gear 28, and drives the fan blade 32 to rotate at high speed through the meshing of the first bevel gear 30 and the second bevel gear 31, which promotes the circulation of glue in the glue box 10 and prevents the glue from solidifying.

[0046] When the glue level in the glue box 10 drops, the float 17 sinks, and the baffle 20 moves down through the support rod 18 and the support plate 19. After the liquid outlet pipe is exposed, the glue in the material box 21 flows into the glue box 10. When the liquid level rises back to the set height, the float 17 floats up, and the baffle 20 resets to block the liquid outlet pipe, thus realizing automatic glue replenishment.

[0047] After the glue is applied, the glue on the surface of the glue roller 7 is evenly transferred to the paper. The paper leaves the glue box 2 and enters the subsequent winding process of the paper tube machine body 1, eventually forming a multi-layer composite high-strength paper tube.

[0048] Through the coordinated operation of the above structures, this invention achieves automation of the gluing process, precise control of glue quantity, and maintenance of glue activity, significantly improving the rolling quality and production efficiency of multi-layer composite high-strength paper tubes.

[0049] 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.
