Description

Technical Field

[0001] This utility model relates to the field of kraft paper self-adhesive film adhesive surface treatment technology, and more specifically, it relates to a kraft paper self-adhesive film adhesive surface treatment device. Background Technology

[0002] In the context of the rapid development of the modern packaging and manufacturing industry, kraft paper self-adhesive film adhesive surface treatment equipment has become an indispensable key piece of equipment in the production line. This type of equipment is specifically designed to address the adhesive surface problems generated during the production and processing of kraft paper self-adhesive film, especially addressing environmental and safety challenges. Some existing kraft paper self-adhesive film adhesive surface treatment devices treat harmful gases emitted from the adhesive surface of the kraft paper self-adhesive film through exhaust gas collection devices. This exhaust gas collection system effectively prevents these harmful gases from polluting the working environment and prevents acute or chronic health hazards to the respiratory system, skin, and eyes of workers, greatly improving the safety of the production environment and compliance with environmental regulations. However, the treatment... The connection and disconnection of pipeline systems in the waste gas treatment process of the equipment is usually cumbersome, with complicated and time-consuming operation procedures. When the production line needs to be adjusted according to different product specifications, or when the pipeline system needs to be disassembled, maintained, or even replaced due to wear and tear from long-term use, operators often need to use a variety of professional tools such as wrenches, screwdrivers, and sealing tape to assist in the operation. This complicated disassembly and assembly process not only greatly increases maintenance time and reduces production efficiency, but may also cause damage to pipeline connection points or poor sealing due to improper operation, resulting in safety hazards such as leakage of harmful gases. This cumbersome connection and disconnection method has become a bottleneck that seriously restricts the flexibility and maintenance efficiency of the equipment, thus making it impossible to achieve convenient inspection and replacement of pipelines.

[0003] Secondly, some equipment manufacturers in the industry have begun to adopt innovative designs, which superficially solve the problem of adjustable fertilization speed. However, these improved designs are still too simple in structure and have low overall stability. These simple connection structures often only consider the convenience of connection, while ignoring the various complex challenges faced by pipeline systems in actual industrial environments. Pipeline systems often face the combined effects of multiple complex factors such as continuous vibration generated during equipment operation and periodic fluctuations in gas pressure inside the pipeline. These simple connection structures are very prone to slight displacement of the fixed structure due to these external interference factors or internal pressure shock fluctuations. Over time and with cumulative effects, these slight displacements gradually develop into obvious loosening or even complete detachment. When the pipeline connection is unstable, it will not only lead to a decrease in system sealing, causing harmful gas leakage, increasing environmental pollution and safety risks, but may also cause direct physical damage to surrounding equipment and personnel, thereby affecting the safety and stability of the entire production system and bringing significant economic losses and safety hazards to the normal production and operation of enterprises. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a kraft paper self-adhesive film adhesive surface treatment device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a kraft paper self-adhesive film adhesive surface treatment device, comprising a machine body, an input compartment detachably provided at the top of the machine body, a quick-clamping device connected to the top of the input compartment, the quick-clamping device comprising a rotating sleeve, a fixed tube, an outer tube, a rotating groove, a connecting frame, an insertion groove, an insertion rod, and a moving plate, the rotating sleeve being rotatably mounted on the outside of the fixed tube, the fixed tube being fixedly mounted on the top of the input compartment, the bottom end of the outer tube being detachably inserted into the inside of the fixed tube, the rotating groove being formed in the rotating sleeve, the insertion groove being formed on the outside of the outer tube, the insertion rod being fixedly connected to one end of the connecting frame, and the insertion... One end of the connecting rod is inserted into the insertion slot. The movable plate is fixedly connected to the other end of the connecting frame. The movable plate slides in the rotating slot. A limiting mechanism is installed on the outside of the fixed tube. The limiting mechanism includes a limiting sleeve, a limiting frame, a moving slot, a limiting spring, a limiting plate, a limiting rod, and a limiting slot. The limiting sleeve is movably connected to the outer wall of the fixed tube by threads. The limiting frame is fixedly installed on one side of the rotating sleeve. The moving slot is opened on the outside of the fixed tube. The two ends of the limiting spring are respectively connected to two adjacent limiting blocks. The limiting plate is fixedly connected to one end of the limiting rod. The limiting rod is slidably installed in the limiting frame. The limiting slots are opened at both ends of the moving slot.

[0008] The present invention is further configured such that both the rotating groove and the moving plate adopt a variable diameter structure design. This variable diameter structure design enables the rotating groove to precisely control the trajectory of the moving plate during rotation, ensuring that the insertion and removal actions of the plug rod and the plug groove are smooth and controllable.

[0009] The present invention is further provided with multiple anti-slip strips fixed on the outer sides of the rotating sleeve and the limiting sleeve. This anti-slip design significantly improves the friction between the operator's hand and the rotating sleeve and the limiting sleeve, ensuring that even in industrial environments where gloves are wet or contaminated with oil, the operator can still firmly grip and accurately control the rotation angle and force, thus improving the convenience and accuracy of operation.

[0010] The present invention is further provided with a detachable sealing sleeve on the inner side of the fixed tube, and a chamfered structure design on one side of the inner wall of the insertion groove and one end of the insertion rod. This sealing design provides the main seal through the detachable sealing sleeve.

[0011] The present invention is further configured such that multiple sealing grooves are provided on the inner side of the fixed pipe, and multiple sealing strips are fixed on the outer side of the outer pipe. The sealing grooves and sealing strips are compatible, and this multi-layer sealing structure forms multiple leak-proof barriers. When the outer pipe is inserted into the fixed pipe, the multiple sealing strips are precisely inserted into the corresponding sealing grooves to form a multi-layer concentric seal, which effectively prevents the leakage of harmful gases under high pressure or vibration environment. Even if a single sealing point ages or is damaged, the remaining sealing points can still maintain the overall sealing performance, which greatly improves the reliability of the system.

[0012] The present invention is further configured such that both the sealing sleeve and the sealing strip are made of rubber. The choice of this material fully considers the actual needs of the industrial environment. Rubber has excellent elastic recovery performance and anti-aging properties, and can maintain a stable sealing effect in environments with temperature fluctuations and contact with chemical substances. At the same time, the moderate deformation capacity of rubber allows the sealing element to adaptively compensate for minor defects or unevenness on the connection surface, providing more reliable sealing performance and extending the service life of the sealing structure.

[0013] The present invention is further configured such that the depth of the limiting groove is greater than the depth of the moving groove. This depth difference design ensures that the limiting rod has sufficient embedding depth after being inserted into the limiting groove, providing a more secure mechanical locking force and preventing the limiting rod from accidentally coming out when the equipment vibrates or the internal pressure of the pipeline fluctuates.

[0014] The present invention is further configured such that the connection between the limiting groove and the moving groove, as well as one end of the limiting rod, adopt a rounded corner structure design. This rounded corner design significantly reduces the wear and resistance between the limiting rod and the groove wall during the sliding process, ensuring that the limiting rod can smoothly transition from the limiting groove to the moving groove, reducing jamming and impact.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a kraft paper self-adhesive film adhesive surface treatment device, which has the following beneficial effects:

[0017] 1. The quick-connect device innovatively solves the key drawback of cumbersome connection and disconnection between pipeline systems in existing kraft paper self-adhesive film adhesive surface treatment devices through the meticulous coordination of a rotating sleeve, fixed pipe, external pipe, rotating groove, connecting frame, insertion slot, insertion rod, and moving plate. This device adopts a rotary drive principle, where the rotational motion of the rotating sleeve drives the internal variable-diameter rotating groove to rotate. Precise mechanical transmission converts the rotational motion into the radial motion of the moving plate, which in turn moves the connecting frame, thereby precisely controlling the insertion and removal states of the insertion rod and insertion slot. This achieves rapid connection and separation of pipelines. This innovative design eliminates the need for operators to use wrenches, screwdrivers, sealing tape, and other specialized tools. The simple rotation operation allows for easy assembly and disassembly of the pipes, significantly simplifying the operation process and greatly reducing maintenance time. Especially in production environments where frequent replacement of different types of processing devices or regular maintenance is required, this quick connection method greatly improves the flexibility and maintenance efficiency of the equipment. It effectively avoids the risk of pipe connection point damage or poor sealing due to improper operation, and prevents the leakage of harmful gases from negatively impacting the environment and workers. It provides a convenient and efficient pipe connection solution for kraft paper self-adhesive film coating devices, fundamentally improving the practicality and safety of the equipment, significantly reducing the company's maintenance costs and downtime, and improving the overall operating efficiency of the production line.

[0018] 2. The limiting mechanism consists of a limiting sleeve, a limiting frame, a moving groove, a limiting spring, a limiting plate, a limiting rod, and a limiting groove. It innovatively solves the fundamental defect of low pipeline connection stability in existing technologies. This mechanism is designed to form a double-insurance anti-loosening system: firstly, the limiting rod engages with the limiting groove to form the first mechanical lock; secondly, the inner wall of the limiting sleeve limits the outer wall of the limiting plate, forming the second layer of protection. In particular, the limiting sleeve adopts a threaded connection design, allowing its axial movement along the outer wall of the fixed pipe to be controlled by rotating the limiting sleeve. This enables the limiting sleeve to precisely apply a limiting effect to the limiting plate, ensuring that the locking structure maintains high stability even under the influence of complex factors such as vibration and internal pipeline pressure fluctuations during equipment operation. The depth of the limiting groove is designed to be greater than the depth of the moving groove. This multi-layered anti-loosening system enhances the locking strength after the limit rod is inserted. The rounded corner design at the connection between the limit groove and the moving groove, as well as at one end of the limit rod, reduces friction and wear, improving the smoothness of operation and service life. This system fundamentally eliminates the possibility of pipe connections loosening or even falling off during use due to external interference or internal pressure fluctuations. It effectively avoids the problem of harmful gas leakage caused by a decrease in system sealing and prevents the risk of direct injury to surrounding equipment and personnel caused by sudden pipe swing due to connection point detachment under high pressure. It provides a stable and reliable working guarantee for the kraft paper self-adhesive film adhesive surface treatment device, significantly improving the safety and service life of the equipment and providing solid technical support for the normal production and operation of enterprises.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0028] Please see Figures 1-5A kraft paper self-adhesive film coating device includes a body 1. An input compartment 2 is detachably mounted on the top of the body 1. A quick-clamping device is connected to the top of the input compartment 2. The quick-clamping device includes a rotating sleeve 3, a fixed tube 4, an outer tube 5, a rotating groove 6, a connecting frame 7, an insertion groove 8, an insertion rod 9, and a moving plate 10. The rotating sleeve 3 is rotatably mounted on the outside of the fixed tube 4, and the fixed tube 4 is fixedly mounted on the top of the input compartment 2. The bottom end of the outer tube 5 is detachably inserted into the inside of the fixed tube 4. The rotating groove 6 is formed in the rotating sleeve 3, the insertion groove 8 is formed on the outside of the outer tube 5, and the insertion rod 9 is fixedly connected to one end of the connecting frame 7, with one end of the insertion rod 9 inserted into the insertion groove 8. The moving plate 10 is fixedly mounted on the outer tube 5. The fixed connection is attached to the other end of the connecting frame 7. The movable plate 10 slides in the rotating groove 6. A limiting mechanism is installed on the outside of the fixed tube 4. The limiting mechanism includes a limiting sleeve 11, a limiting frame 12, a moving groove 13, a limiting spring 14, a limiting plate 15, a limiting rod 16, and a limiting groove 17. The limiting sleeve 11 is movably connected to the outer wall of the fixed tube 4 by threads. The limiting frame 12 is fixedly installed on one side of the rotating sleeve 3. The moving groove 13 is opened on the outside of the fixed tube 4. The two ends of the limiting spring 14 are respectively connected to two adjacent limiting blocks. The limiting plate 15 is fixedly connected to one end of the limiting rod 16. The limiting rod 16 is slidably installed in the limiting frame 12. The limiting groove 17 is opened at both ends of the moving groove 13.

[0029] In this embodiment, when the pipeline needs to be replaced or repaired, the outer pipe 5 must first be removed. First, the limiting sleeve 11 is rotated forward, causing it to move along the thread on the outer wall of the fixed pipe 4, so that the limiting sleeve 11 gradually stops limiting the outer wall of the limiting plate 15. Then, the rotating sleeve 3 is rotated forward, which will drive the limiting frame 12 on one side to rotate forward. The limiting frame 12 will also drive the limiting rod 16, the limiting plate 15, and the limiting spring 14 to rotate forward. Then, the inner wall of the limiting groove 17 presses against one end of the limiting rod 16. Due to the rounded corner design at the connection between the limiting groove 17 and the moving groove 13, and the rounded corner design at one end of the limiting rod 16, one end of the limiting rod 16 gradually slides out of the limiting groove 17 and into the moving groove 13. The sliding mechanism is as follows: the limit rod 16 slides through the limit plate 15, which in turn stretches the limit spring 14. At the same time, the rotating sleeve 3 drives the inner variable-diameter rotating groove 6 to rotate in the forward direction, causing the moving plate 10 to move in the rotating groove 6. Then, the moving plate 10 drives the plug rod 9 to gradually slide out of the plug groove 8 through the connecting frame 7. At this time, the limit rod 16 gradually rotates to the position corresponding to another limit groove 17. Then, the limit spring 14 pulls the limit rod 16 through the limit plate 15 to slide and reset, so that one end of the limit rod 16 is inserted into the limit groove 17. Then, the other part is unlocked according to the above steps. Then, the outer pipe 5 is pulled upward to remove the outer pipe 5, and then the maintenance or replacement of the outer pipe 5 can be achieved.

[0030] Please see Figures 3-5As a further implementation of the overall equipment: both the rotating groove 6 and the moving plate 10 adopt a variable diameter structure design.

[0031] Multiple anti-slip strips 18 are fixedly provided on the outer sides of both the rotating sleeve 3 and the limiting sleeve 11.

[0032] The inner side of the fixed tube 4 is detachably equipped with a sealing sleeve 19, and one side of the inner wall of the insertion groove 8 and one end of the insertion rod 9 are both designed with a chamfered structure.

[0033] Multiple sealing grooves 20 are provided on the inner side of the fixed pipe 4, and multiple sealing strips 21 are fixed on the outer side of the outer pipe 5. The sealing grooves 20 and sealing strips 21 are compatible.

[0034] Both the sealing sleeve 19 and the sealing strip 21 are made of rubber.

[0035] The depth of the limiting groove 17 is greater than the depth of the moving groove 13.

[0036] The connection between the limiting groove 17 and the moving groove 13, as well as one end of the limiting rod 16, all adopt a rounded corner structure design.

[0037] More specifically, after the external connecting pipe 5 has been inspected or replaced, the bottom end of the external connecting pipe 5 is reinserted into the corresponding fixed pipe 4, so that the external connecting pipe 5 abuts against the sealing sleeve 19. Then, the rotating sleeve 3 is rotated in the opposite direction. The rotating sleeve 3 will drive the limiting frame 12 on one side to rotate in the opposite direction. Then, the limiting frame 12 will drive the limiting rod 16, the limiting plate 15, and the limiting spring 14 to rotate in the opposite direction. Then, the connection between the limiting groove 17 and the moving groove 13 will press against one end of the limiting rod 16, causing the limiting rod 16 to slide out of the moving groove 13 and into the moving groove. In step 13, the sliding motion proceeds in the opposite direction. Then, the other end of the limiting rod 16 is stretched outward again by the limiting plate 15, causing the limiting spring 14 to move outward. At the same time, the rotating sleeve 3 drives the inner variable-diameter rotating groove 6 to rotate in the opposite direction. Then, the moving plate 10 moves in the opposite direction in the rotating groove 6, causing the moving plate 10 to slide inward through the connecting frame 7, so that the insert rod 9 is re-inserted into the insert groove 8. Due to the chamfer design on one side of the inner wall of the insert groove 8 and one end of the insert rod 9, when the insert rod 9 is fully inserted into the insert groove 8, the insert rod 9 passes through the insert groove 8. The outer connecting pipe 5 presses the sealing sleeve 19 against the inside of the fixed pipe 4, ensuring the sealing of the pipe connection. Simultaneously, multiple sealing strips 21 on the outside of the outer connecting pipe 5 are inserted into the corresponding sealing grooves 20, forming a multi-layer sealing structure, further improving the sealing performance of the pipe connection. At this time, the limiting frame 12 rotates the limiting rod 16 and other components to the position corresponding to the original moving groove 13. Then, the limiting spring 14 pulls the limiting plate 15 to slide inward, causing the limiting plate 15 to slide the limiting rod 16 inward to reset, thus allowing the limiting rod... One end of 16 is reinserted into the original limiting groove 17, and then the limiting sleeve 11 is rotated in the opposite direction. The limiting sleeve 11 moves in the opposite direction along the thread on the outer wall of the fixed pipe 4, so that the limiting sleeve 11 moves and resets. This causes the inner wall of the limiting sleeve 11 to limit the outer wall of the limiting plate 15 again, preventing the movement of the limiting plate 15 and the limiting rod 16. Then the limiting rod 16 and the limiting groove 17 cooperate to limit the limiting frame 12, so that the limiting frame 12 and the rotating sleeve 3 will not rotate, thereby ensuring the stability of the pipeline connection and ensuring the stable use of the pipeline system.

[0038] In summary, when the entire equipment is in use or operation: when it is necessary to replace or repair the pipeline, the outer pipe 5 should be removed first. First, rotate the limiting sleeve 11 in the forward direction, so that the limiting sleeve 11 moves along the thread on the outer wall of the fixed pipe 4, thereby gradually removing the limiting sleeve 11 from the outer wall of the limiting plate 15. Then, rotate the rotating sleeve 3 in the forward direction. The rotating sleeve 3 will drive the limiting frame 12 on one side to rotate in the forward direction, and the limiting frame 12 will drive the limiting rod 16, the limiting plate 15, and the limiting spring 14 to rotate in the forward direction. Then, the inner wall of the limiting groove 17 will press against one end of the limiting rod 16. Due to the rounded corner design at the connection between the limiting groove 17 and the moving groove 13, the rounded corner design at one end of the limiting rod 16 will cause one end of the limiting rod 16 to gradually slide out of the limiting groove 17 and into the moving groove 13. The moving plate 10 slides in the moving groove 13, and the other end of the limiting rod 16 is stretched by the limiting plate 15 driving the limiting spring 14. At the same time, the rotating sleeve 3 will drive the inner variable diameter opening of the rotating groove 6 to rotate in the forward direction, so that the moving plate 10 moves in the rotating groove 6. Then the moving plate 10 will drive the plug rod 9 to gradually slide out of the plug groove 8 through the connecting frame 7. At this time, the limiting rod 16 gradually rotates to the position corresponding to another limiting groove 17. Then the limiting spring 14 pulls the limiting rod 16 through the limiting plate 15 to slide and reset, so that one end of the limiting rod 16 is inserted into the limiting groove 17. Then, the other part is unlocked according to the above steps. Then the outer pipe 5 is pulled upward to remove the outer pipe 5, and then the maintenance or replacement of the outer pipe 5 can be realized.

[0039] After the external connector 5 has been inspected or replaced, reinsert the bottom end of the external connector 5 into the corresponding fixed pipe 4, ensuring that the external connector 5 abuts against the sealing sleeve 19. Then, rotate the rotating sleeve 3 in the reverse direction. The rotating sleeve 3 will cause one side of the limiting frame 12 to rotate in the reverse direction. The limiting frame 12 will then cause the limiting rod 16, the limiting plate 15, and the limiting spring 14 to rotate in the reverse direction. The connection between the limiting groove 17 and the moving groove 13 will then press against one end of the limiting rod 16, causing the limiting rod 16 to slide out of the moving groove 13 and into the moving groove 13. The sliding motion proceeds in the reverse direction. Then, the other end of the limiting rod 16 is stretched outward again by the limiting plate 15, causing the limiting spring 14 to move outward. At the same time, the rotating sleeve 3 drives the inner variable-diameter rotating groove 6 to rotate in the reverse direction. Then, the moving plate 10 moves in the reverse direction in the rotating groove 6, causing the moving plate 10 to drive the insertion rod 9 to slide inward through the connecting frame 7, so that the insertion rod 9 is re-inserted into the insertion groove 8. Due to the chamfer design on one side of the inner wall of the insertion groove 8 and one end of the insertion rod 9, when the insertion rod 9 is fully inserted into the insertion groove 8, the insertion rod 9 is driven by the insertion groove 8 to move inward. The outer pipe 5 presses the sealing sleeve 19 against the inside of the fixed pipe 4 to ensure the sealing of the pipe connection. At the same time, multiple sealing strips 21 set on the outside of the outer pipe 5 will be simultaneously inserted into the corresponding sealing grooves 20, forming a multi-layer sealing structure, which further improves the sealing performance of the pipe connection. At this time, the limiting frame 12 drives the limiting rod 16 and other components to rotate to the position corresponding to the original moving groove 13. Then, the limiting spring 14 pulls the limiting plate 15 to slide inward, so that the limiting plate 15 drives the limiting rod 16 to slide and reset inward. Then, the limiting rod 16... One end of the 6 is reinserted into the original limiting groove 17, and then the limiting sleeve 11 is rotated in the opposite direction. The limiting sleeve 11 moves in the opposite direction along the thread on the outer wall of the fixed pipe 4, so that the limiting sleeve 11 moves and resets. This causes the inner wall of the limiting sleeve 11 to limit the outer wall of the limiting plate 15 again, preventing the movement of the limiting plate 15 and the limiting rod 16. Then the limiting rod 16 and the limiting groove 17 cooperate to limit the limiting frame 12, so that the limiting frame 12 and the rotating sleeve 3 will not rotate, thereby ensuring the stability of the pipeline connection and ensuring the stable use of the pipeline system.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
