Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology in paper product manufacturing, and more specifically, it relates to adhesive application equipment for paper product manufacturing. Background Technology

[0002] In paper product manufacturing, glue application equipment requires pipes to connect the glue delivery equipment to a buffer tank equipped with a coating head, thus ensuring glue supply. However, in existing technologies, connecting or disconnecting the pipes from the buffer tank is usually cumbersome and requires specialized tools such as wrenches and screwdrivers. More importantly, during paper product manufacturing, the glue system often needs regular cleaning and maintenance to prevent the glue from drying, clumping, and clogging the system. This necessitates disassembling and reconnecting the pipes to the buffer tank. Traditional connection methods often use threaded or flanged connections, requiring the complete removal of multiple fasteners each time. This not only consumes significant time and labor costs but also easily leads to glue leakage due to improper operation, affecting production efficiency and equipment utilization, and causing inconvenience in maintaining the buffer tank.

[0003] Secondly, although some equipment achieves convenient connection and disconnection between pipelines and buffer bins without tool assistance through the cooperation of some components, its simple structural design lacks sufficient pressure resistance and vibration resistance, resulting in insufficient stability. During the paper product manufacturing process, the pressure fluctuations and pulsations generated during glue pumping, coupled with the continuous vibration of the production equipment itself, can easily lead to loosening or even detachment of the connection structure due to the combined effects of a sudden increase in internal pipeline pressure and continuous vibration of the production equipment. Once the connection fails, it will not only cause glue leakage, resulting in material waste and environmental pollution, but more seriously, it may cause glue splashing and injure operators. In addition, unstable connection will also lead to uneven glue supply, affecting the glue coating quality and the bonding strength of paper products, thereby reducing the quality of finished products and increasing the scrap rate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a paper product manufacturing glue application device, which has the following beneficial effects:

[0017] 1. Through an innovative quick-connect structure, this device solves the technical challenge of traditional glue application equipment requiring specialized tools for connecting and disconnecting pipes and buffer chambers. The design employs a detachable connection between the access pipe and the connecting pipe, combined with a sliding outer sleeve and a rotating operating frame, forming a linked structure. This eliminates the need for tools to connect or disconnect the connecting pipe and buffer chamber. To disconnect, simply rotate the operating frame forward. The operating frame, via a shaft, moves the sleeve, removing it from its position on the mating plate. This causes a return spring to push the mating plate outward, allowing one end of the insert rod to slide out of the insert groove. Finally, gently pull out the connecting pipe to complete the disassembly. For reconnection, simply insert the connecting pipe into the access pipe and rotate the operating frame in the opposite direction to lock and secure it. The entire operation requires no specialized tools, is simple and intuitive, and significantly improves equipment maintenance efficiency and emergency response capabilities. Even without tools, the operation can be easily completed, effectively avoiding production line downtime losses and operational errors caused by complex connection procedures. Especially in production environments requiring glue system cleaning and maintenance, it can quickly respond to maintenance needs, significantly improving equipment practicality and user experience.

[0018] 2. Through a meticulously designed multi-locking and sealing system, the problem of insufficient stability in traditional connection structures is solved. This structure adopts a precise insertion and engagement of the embedded rod and the embedded groove to form the first mechanical lock; the rotating wheel on the positioning block and the locking block's locking mechanism, through the rotating wheel engaging between two adjacent locking blocks, form the second anti-loosening safety; the adapter's limiting of the rotating wheel forms the third anti-vibration protection; at the same time, the adapter rod's supporting limiting of the adapter further enhances the stability of the connection. In terms of sealing performance, the sealing sleeve compression design inside the connecting tube and the precise engagement of multiple sealing rings on the outside of the connecting tube with the embedded groove form a multi-layer sealing structure; the chamfered design of the embedded rod and the embedded groove makes the connection tighter and more reliable. This multi-locking and sealing design enables the connection structure to effectively resist the adverse effects of glue pressure fluctuations, equipment vibration, and external mechanical impacts during the paper product manufacturing process, effectively preventing material waste and environmental pollution caused by glue leakage, ensuring the personal safety of operators, while ensuring a uniform and stable glue supply, guaranteeing finished product quality, reducing scrap rate, and reducing wear on related components.

[0029] Please see Figures 1-6A paper product manufacturing adhesive application device includes a support frame 1, a buffer chamber 2 on one side of the support frame 1, a passage pipe 3 connected to the top of the buffer chamber 2, a connecting pipe 4 detachably provided inside the passage pipe 3, a mounting plate 5 rotatably provided outside the passage pipe 3, a mating sleeve 6 slidably fitted outside the passage pipe 3, an adapter hole 7 opened on the mounting plate 5, an adapter sleeve 8 slidably fitted outside the passage pipe 3, an operating frame 9 rotatably fitted outside the passage pipe 3, a shaft 10 fixed inside the operating frame 9, the mating sleeve 6 and the shaft 10 being slidably connected, an adapter rod 11 fixedly connected to one side of the adapter sleeve 8, a cooperating block 12 fixedly provided on one side of the mounting plate 5, a connecting block 13 fixedly provided outside the passage pipe 3, a cooperating spring 14 connecting the cooperating block 12 and the connecting block 13, and a fixed fixed spring 14 movably provided on one side of the operating frame 9. Positioning block 15, the side wall of the passage pipe 3 is provided with an embedded rod 16, one end of the embedded rod 16 is fixedly connected to a mating plate 17, the outside of the connecting pipe 4 is provided with an embedded groove 18, the other end of the embedded rod 16 is inserted into the embedded groove 18, the outside of the passage pipe 3 is provided with a spiral guide groove 19, the outside of the adapter rod 11 is movably sleeved with an installation spring 20, one end of the installation spring 20 is connected to the adapter 8, the other end of the installation spring 20 abuts against one side of the mounting plate 5, multiple locking blocks 21 are fixedly provided on the outside of the passage pipe 3, a tension spring 22 is provided on one side of the positioning block 15, the two ends of the tension spring 22 are respectively connected to two adjacent positioning blocks 15, the inside of the mating sleeve 6 is fixedly provided with a configuration block 23, the configuration block 23 is slidably in the guide groove 19, and the other end of the connecting pipe 4 is connected to the output end of an external glue delivery device.

[0030] A winding wheel 24 is rotatably mounted on one side of the bracket 1, and multiple guide wheels 25 are rotatably mounted on one side of the bracket 1. A mounting frame 26 is provided on one side of the guide wheel 25. The mounting frame 26 is detachably mounted on one side of the bracket 1. The buffer bin 2 is detachably mounted on top of the mounting frame 26. A glue brushing wheel 27 is rotatably mounted in the mounting frame 26. A coating head 28 is connected to one side of the buffer bin 2, and one end of the coating head 28 is located above the glue brushing wheel 27.

[0031] In this embodiment, when it is necessary to disconnect the connecting pipe 4 from the buffer compartment 2, the mounting plate 5 is first rotated forward, causing the mounting plate 5 to drive the cooperating block 12 on one side to rotate forward. Then, the cooperating block 12 will drive the cooperating rod 36 on one side to rotate along the cooperating hole 37. The cooperating block 12 will cooperate with the connecting block 13 to compress the cooperating spring 14. The mounting plate 5 will simultaneously drive the adapter hole 7 to rotate forward. When the cooperating spring 14 is compressed to its limit, the adapter hole 7 will just rotate to a position concentric with the adapter rod 11. Then, the adapter 8 will be pushed, and the adapter 8 will drive the inner guide block 38 to slide along the guide groove 39. Furthermore, the adapter 8 will simultaneously drive the adapter rod 11 on one side to slide, allowing the adapter rod 11 to slide into the adapter hole 7. At the same time, the adapter 8 will cooperate with the mounting plate 5 to compress the mounting spring 20, causing the adapter 8 to gradually stop limiting the outer side of the rotating wheel 29. Then, the operating frame 9 will rotate forward, causing multiple positioning rails 31 on one side to rotate forward. The positioning rails 31 will then drive the positioning block 15 and the rotating wheel 29 to rotate forward through the limiting groove 30, causing the rotating wheel 29 to gradually roll out between two adjacent locking blocks 21. The rotating wheel 29 will also drive the positioning block 15 along the positioning rail 31. 1. Slide outwards, and the positioning block 15 will cause the tension spring 22 to stretch outwards. At the same time, the operating frame 9 will cause the shaft 10 to rotate in the forward direction, so that the shaft 10 will drive the two mating sleeves 6 to rotate synchronously in the same direction. Then, the mating sleeve 6 will drive the inner configuration block 23 to slide along the guide groove 19. Since the two guide grooves 19 are designed with opposing structures, the two mating sleeves 6 will synchronously drive the inner configuration block 23 to slide along the shaft 10 to both sides, so that the distance between the two mating sleeves 6 will be lengthened. Then, the inner wall of the mating sleeve 6 will gradually no longer limit the outer wall of the mating plate 17. Then, the return spring 35 will reset and push the mating plate. 17. This causes the mating plate 17 to slide the one-sided embedded rod 16 outward, so that one end of the embedded rod 16 gradually slides out of the embedded groove 18. Then, the connecting tube 4 is pulled upward, so that one end of the connecting tube 4 is pulled out of the passage tube 3, thus disconnecting the connection between the connecting tube 4 and the buffer chamber 2. Then, the buffer chamber 2 can be removed from the mounting bracket 26 by common means in the prior art, such as using a wrench or screwdriver to remove the bolts fixing the buffer chamber 2. Then, the buffer chamber 2 can be removed for maintenance, cleaning, or even replacement. After maintenance, cleaning, or replacement, the buffer chamber 2 can be re-fixed to the mounting bracket 26.

[0032] Please see Figures 3-6 As a further implementation of the overall equipment: a rotating wheel 29 is provided on one side of the positioning block 15, and the rotating wheel 29 is engaged between two adjacent locking blocks 21. A limiting groove 30 is provided in the positioning block 15. A positioning rail 31 is fixedly connected to one side of the operating frame 9. The positioning block 15 is slidably installed on the outside of the positioning rail 31 through the limiting groove 30.

[0033] The passage pipe 3 is detachably equipped with a sealing sleeve 32. One end of the embedded rod 16 and one side of the inner wall of the embedded groove 18 are both designed with a chamfer structure. Multiple fitting grooves 33 are opened on the inner side of the passage pipe 3. Multiple sealing rings 34 are fixed on the outer side of the connecting pipe 4. The sealing rings 34 are inserted into the corresponding fitting grooves 33.

[0034] A return spring 35 is connected to the inner side of the mating plate 17, and the other end of the return spring 35 is connected to the outer wall of the passage pipe 3.

[0035] The two mating sets 6 are arranged opposite each other, and the two guide slots 19 are opened opposite each other.

[0036] A cooperating rod 36 is fixedly connected to one side of the cooperating block 12, and a cooperating hole 37 is opened in the connecting block 13. One end of the cooperating rod 36 slides into the cooperating hole 37, and the cooperating spring 14 is movably sleeved on the outside of the cooperating rod 36.

[0037] The inner side of the fitting 8 is fixedly provided with a guide block 38, and the outer side of the passage pipe 3 is provided with a guide groove 39, and the guide block 38 slides in the guide groove 39.

[0038] More specifically, when it is necessary to reconnect the connecting pipe 4 to the buffer compartment 2, first insert one end of the connecting pipe 4 into the passage pipe 3, so that the connecting pipe 4 abuts against the sealing sleeve 32. Then, rotate the operating frame 9 in the reverse direction, so that the operating frame 9 drives the positioning block 15, the rotating wheel 29 and the tension spring 22 to rotate in the reverse direction through the cooperation of the positioning rail 31 and the limiting groove 30. The operating frame 9 also drives the two mating sleeves 6 to rotate in the reverse direction through the inner shaft 10. Then, the two mating sleeves 6 drive the inner configuration block 23 to slide in the reverse direction along the guide groove 19, so that the two mating sleeves 6 slide inward synchronously, shortening the distance between the two mating sleeves 6. Due to the chamfer design of the inner wall edge of the mating sleeve 6 and the outer wall of the mating plate 17, the inner wall of the mating sleeve 6 will gradually push the mating plate. 17 is pressed inward, causing the mating plate 17 to slide inward on one side of the embedded rod 16. The mating plate 17 also compresses the return spring 35 on one side. Then, the embedded rod 16 gradually inserts into the embedded groove 18. Due to the chamfer design at one end of the embedded rod 16 and the inner wall edge of the embedded groove 18, when one end of the embedded rod 16 is reinserted into the embedded groove 18, the embedded rod 16, through the chamfer structure in the embedded groove 18, drives the connecting pipe 4 to slide inward into the passage pipe 3. This causes the connecting pipe 4 to press the sealing sleeve 32 tightly, ensuring the sealing of the connection. At the same time, multiple sealing rings 34 are set on the outside of the connecting pipe 4 and simultaneously inserted into the corresponding fitting grooves 33, forming a multi-layer sealing structure, thereby further strengthening the sealing strength at the connection between the connecting pipe 4 and the passage pipe 3. At this time, the positioning rail 31... The limiting groove 30 drives the positioning block 15 and the rotating wheel 29 on one side to rotate and reset to the original position between the two locking blocks 21. Then, the tension spring 22 resets and pulls the positioning block 15, causing the positioning block 15 to drive the limiting groove 30 to slide inward along the positioning rail 31. The positioning block 15 will also drive the rotating wheel 29 on one side to re-lock between the original two locking blocks 21. Then, the adapter 8 is released, and the mounting spring 20 resets and pushes the adapter 8. The adapter 8 will drive the guide block 38 to slide and reset along the guide groove 39, while simultaneously driving the adapter rod 11 on one side to slide and reset. When the mounting spring 20 is fully reset, the adapter rod 11 no longer passes into the adapter hole 7. At this time, the cooperating spring 14 resets and pushes the cooperating block 12, causing the cooperating block 12 to drive the cooperating rod 36 on one side to slide and reset along the guide groove 39. The moving hole 37 rotates in the reverse direction to reset, and the cooperating block 12 synchronously drives the mounting plate 5 to rotate in the reverse direction, causing the mounting plate 5 to drive the adapter hole 7 to rotate in the reverse direction to reset to a position that does not correspond to the adapter rod 11. Then, the adapter rod 11 supports the adapter 8 to one side of the mounting plate 5. With the help of the guide block 38 and the guide groove 39, the adapter 8 is limited, so that the adapter 8 will not move. Then, the inner wall of the adapter 8 limits the outer side of the rotating wheel 29 again, so that the rotating wheel 29 cannot move outward, thereby preventing the positioning block 15 from moving outward. The rotation limit of the operating frame 9 is achieved through the cooperation of the limiting groove 30 and the positioning rail 31, thereby ensuring a stable connection between the buffer tank 2 and the connecting pipe 4, and ensuring a stable supply of glue. Since the glue application equipment is a mature technology in the existing technology,Therefore, the specific structure and operating principle of the glue application equipment will not be described or demonstrated in detail.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to disconnect the connecting pipe 4 from the buffer chamber 2, firstly, rotate the mounting plate 5 in the forward direction, causing the mounting plate 5 to drive the cooperating block 12 on one side to rotate in the forward direction. Then, the cooperating block 12 will drive the cooperating rod 36 on one side to rotate along the cooperating hole 37. The cooperating block 12 will cooperate with the connecting block 13 to compress the cooperating spring 14. Simultaneously, the mounting plate 5 will drive the adapter hole 7 to rotate in the forward direction. When the cooperating spring 14 is compressed to its limit, the adapter hole 7 will just rotate to a position concentric with the adapter rod 11. Then, push the adapter 8. The adapter 8 will drive the inner guide block 38 along the guide... The adapter slides into the groove 39, and the adapter 8 simultaneously drives the adapter rod 11 on one side to slide, so that the adapter rod 11 slides into the adapter hole 7. At the same time, the adapter 8 and the mounting plate 5 cooperate to compress the mounting spring 20, so that the adapter 8 gradually stops limiting the outer side of the rotating wheel 29. Then, the operating frame 9 rotates forward, and the operating frame 9 drives multiple positioning rails 31 on one side to rotate forward. Then, the positioning rails 31 drive the positioning block 15 and the rotating wheel 29 to rotate forward through the limiting groove 30, so that the rotating wheel 29 gradually rolls out between two adjacent locking blocks 21, and the rotating wheel 29 drives the positioning block 15 along the groove 30. As the positioning rail 31 slides outward, the positioning block 15 will cause the tension spring 22 to stretch outward. At the same time, the operating frame 9 will cause the shaft 10 to rotate in the forward direction, so that the shaft 10 will drive the two mating sleeves 6 to rotate synchronously in the same direction. Then, the mating sleeve 6 will cause the inner configuration block 23 to slide along the guide groove 19. Since the two guide grooves 19 are designed with opposing structures, the two mating sleeves 6 will synchronously drive the inner configuration block 23 to slide along the shaft 10 to both sides, so that the distance between the two mating sleeves 6 will increase. Then, the inner wall of the mating sleeve 6 will gradually no longer limit the outer wall of the mating plate 17. Then, the return spring 35 will reset and push the mating plate 17 to move outward. The mating plate 17 causes the mating plate 17 to slide the one-sided embedded rod 16 outward, so that one end of the embedded rod 16 gradually slides out of the embedded groove 18. Then, the connecting tube 4 is pulled upward, so that one end of the connecting tube 4 is pulled out of the passage tube 3, thus disconnecting the connecting tube 4 from the buffer chamber 2. Then, the buffer chamber 2 can be removed from the mounting bracket 26 by common means in the prior art, such as using a wrench or screwdriver to remove the bolts fixing the buffer chamber 2. Then, the buffer chamber 2 can be removed for maintenance, cleaning or even replacement. After maintenance, cleaning or replacement is completed, the buffer chamber 2 can be re-fixed to the mounting bracket 26.

[0040] When it is necessary to reconnect the connecting pipe 4 to the buffer compartment 2, first insert one end of the connecting pipe 4 into the passage pipe 3, so that the connecting pipe 4 abuts against the sealing sleeve 32. Then, rotate the operating frame 9 in the reverse direction, so that the operating frame 9 drives the positioning block 15, the rotating wheel 29 and the tension spring 22 to rotate in the reverse direction through the cooperation of the positioning rail 31 and the limiting groove 30. The operating frame 9 also drives the two mating sleeves 6 to rotate in the reverse direction through the inner shaft 10. Then, the two mating sleeves 6 drive the inner configuration block 23 to slide in the reverse direction along the guide groove 19, so that the two mating sleeves 6 slide inward synchronously, shortening the distance between the two mating sleeves 6. Due to the chamfer design of the inner wall edge of the mating sleeve 6 and the outer wall of the mating plate 17, the inner wall of the mating sleeve 6 will gradually push the mating plate 17 inward. The side pressing causes the mating plate 17 to slide the embedded rod 16 inward, and the mating plate 17 will compress the return spring 35 on one side. Then the embedded rod 16 will gradually be inserted into the embedded groove 18. Due to the chamfer design at the edge of the inner wall of the embedded groove 18, when the embedded rod 16 is reinserted into the embedded groove 18, the embedded rod 16, through the chamfer structure in the embedded groove 18, drives the connecting pipe 4 to slide inward into the passage pipe 3, so that the connecting pipe 4 presses the sealing sleeve 32 tightly to ensure the sealing of the connection. At the same time, multiple sealing rings 34 are set on the outside of the connecting pipe 4 and simultaneously inserted into the corresponding fitting grooves 33 to form a multi-layer sealing structure, thereby further strengthening the sealing strength at the connection between the connecting pipe 4 and the passage pipe 3. At this time, the positioning rail 31 passes through the limit The groove 30 drives the positioning block 15 and the rotating wheel 29 on one side to rotate and reset to the original position between the two locking blocks 21. Then, the tension spring 22 resets and pulls the positioning block 15, causing the positioning block 15 to drive the limiting groove 30 to slide and reset along the positioning rail 31. The positioning block 15 will also drive the rotating wheel 29 on one side to re-lock between the original two locking blocks 21. Then, the adapter 8 is released, and the mounting spring 20 resets and pushes the adapter 8. The adapter 8 will drive the guide block 38 to slide and reset along the guide groove 39, while simultaneously driving the adapter rod 11 on one side to slide and reset. When the mounting spring 20 is fully reset, the adapter rod 11 no longer passes into the adapter hole 7. At this time, the cooperating spring 14 resets and pushes the cooperating block 12, causing the cooperating block 12 to drive the cooperating rod 36 on one side along the cooperating hole. 37. Reverse rotation resets the mounting plate 5, and the cooperating block 12 will synchronously drive the mounting plate 5 to rotate in the reverse direction, causing the mounting plate 5 to drive the adapter hole 7 to rotate in the reverse direction and reset to a position that does not correspond to the adapter rod 11. Then, the adapter rod 11 supports the adapter 8 to one side of the mounting plate 5. With the help of the guide block 38 and the guide groove 39, the adapter 8 is limited, so that the adapter 8 will not move. Then, the inner wall of the adapter 8 re-limits the outer side of the rotating wheel 29, so that the rotating wheel 29 cannot move outward, thereby preventing the positioning block 15 from moving outward. The rotation limit of the operating frame 9 is achieved through the cooperation of the limiting groove 30 and the positioning rail 31, thereby ensuring the stable connection between the buffer tank 2 and the connecting pipe 4 and ensuring the stable supply of glue. Since the glue application equipment is a mature technology in the existing technology,Therefore, the specific structure and operating principle of the glue application equipment will not be described or demonstrated in detail.
