Description

Technical Field

[0001] This utility model relates to the field of paper tube adhesive production technology, specifically a filtration device for paper tube adhesive production. Background Technology

[0002] Currently, filtration is a crucial step in ensuring product quality during the production of paper tube adhesives. While existing filtration devices for paper tube adhesive production can separate impurities from the adhesive solution to some extent, they still have many shortcomings in practical applications. For example, traditional filtration devices typically use a fixed filter screen structure. This design is prone to clogging after prolonged operation, leading to decreased filtration efficiency. Furthermore, cleaning and replacing the filter screen is cumbersome and time-consuming. In addition, existing devices often lack effective sealing and clamping mechanisms during feeding and filtration, easily causing adhesive leakage or the entry of external impurities, thus affecting product purity and the cleanliness of the production environment. On the other hand, current equipment has a low level of automation, relying on manual intervention, which not only increases labor intensity but may also lead to quality problems caused by improper human operation. Therefore, developing a highly efficient, easy-to-maintain, and automated filtration device for paper tube adhesive production has become a pressing technical challenge for the industry. This utility model proposes an innovative solution to the above problems, aiming to improve filtration efficiency, simplify maintenance procedures, and enhance equipment reliability and automation. Utility Model Content

[0003] This invention addresses the problems of low filtration efficiency, complex operation, and inconvenient filter replacement in existing paper tube adhesive production filtration devices. It provides a filtration device with a reasonable structure, convenient operation, and high filtration efficiency. Through optimized overall structural design, particularly the implementation of the filtration system, lifting mechanism, locking mechanism, and clamping device, the device significantly improves the stability and ease of operation of the filtration process.

[0004] This utility model provides a filtration device for paper tube adhesive production, including a frame, a filtration system, a lifting mechanism, a locking mechanism, and a pressing device. The frame serves as the supporting structure for the entire device. A filter hopper is fixed to its top with nuts and bolts. A discharge pipe is connected to the bottom of the filter hopper via a flange, and a valve is installed on the discharge pipe to control material discharge. Furthermore, guide rods are symmetrically arranged on the top of the frame, and an arc-shaped frame is fixedly connected to the top of the guide rods. A cylinder is mounted on the arc-shaped frame, and a piston rod is fixedly connected to the output end of the cylinder for driving the lifting chamber to move up and down.

[0005] Furthermore, the filtration system includes a filter bucket, a filter screen, and a fixing frame. The filter bucket is used to receive and store the paper tube adhesive to be filtered, and a fixing frame is detachably fixed to its top. The filter screen is fixed to the middle of the fixing frame by screws for filtering impurities in the paper tube adhesive. In particular, the connection between the fixing frame and the filter bucket is achieved by a locking mechanism for quick locking and unlocking, facilitating the replacement and cleaning of the filter screen.

[0006] Furthermore, the lifting mechanism includes a guide rod, an arc-shaped frame, a cylinder, a piston rod, a connecting block, a lifting chamber, and lifting blocks. The guide rods are symmetrically arranged on the top of the frame to guide the vertical movement of the lifting chamber. The arc-shaped frame is fixed to the top of the guide rod to support the cylinder. The cylinder is mounted on the arc-shaped frame, and its output end is fixedly connected to a piston rod. A connecting block is fixed to the end of the piston rod, and a lifting chamber is fixed to one side of the connecting block. Both sides of the lifting chamber are provided with integrally formed lifting blocks. Guide holes are opened inside the lifting blocks, and the guide rod is slidably connected to the corresponding guide holes to ensure smooth movement of the lifting chamber. Specifically, a feeding chamber communicating with the interior of the lifting chamber is also fixed to one side of the lifting chamber. The end of the feeding chamber has a feeding port for feeding the paper tube adhesive to be filtered into the lifting chamber.

[0007] Furthermore, the locking mechanism includes an insert plate, an inner groove, a lever, a locking block, a through groove, a spring, and a connecting plate. The insert plate is located at the top of the filter hopper and is adapted to the insertion hole on the fixed frame for fixing the fixed frame. The insert plate has an inner groove inside, and the filter hopper and the insert plate have a through groove that communicates with the inner groove. Symmetrically arranged levers are slidably connected to the through groove, and each lever is welded with a connecting plate. One end of the connecting plate is fixedly connected to a locking block with an inclined top. The locking block is slidably connected to the inner groove, and a spring is fixedly connected between the locking block and the side wall of the inner groove. When it is necessary to replace or clean the filter screen, the lever is moved to disengage the locking block from the inner groove, and the fixed frame can be quickly disassembled.

[0008] Furthermore, the pressing device includes a pressing block. An integrally formed pressing block is provided on the inner wall of the lifting chamber near the bottom. When the lifting chamber descends, the pressing block presses against the fixed frame, ensuring the stability of the filtration process. Specifically, the shape and size of the pressing block are precisely designed so that it can completely fit the contact surface of the fixed frame, thereby avoiding uneven filtration caused by poor sealing.

[0009] The working principle of this utility model is as follows: S1, the paper tube glue to be filtered is fed into the lifting chamber through the feed port; S2, the cylinder is started, and the cylinder drives the piston rod to drive the lifting chamber to descend along the guide rod until the pressure block presses the fixed frame; S3, the paper tube glue is filtered by the filter screen and discharged through the discharge pipe; S4, when the filter screen needs to be replaced or cleaned, the cylinder drives the lifting chamber to rise, and the paddle is moved to make the locking block disengage from the inner groove, and the fixed frame is removed for cleaning or replacement.

[0010] The technical advantages of this invention are reflected in the following aspects: First, the cooperation between the filter screen and the pressing device achieves a highly efficient and stable filtration process, significantly improving the quality of the paper tube adhesive. Second, the use of a lifting mechanism and locking mechanism enables rapid replacement and cleaning of the filter screen, reducing maintenance time. Third, the design of the guide rod and lifting block ensures the smooth movement of the lifting chamber, avoiding uneven filtration caused by vibration. Finally, the device has a simple structure, is easy to manufacture and maintain, and is suitable for various paper tube adhesive production scenarios.

[0011] In particular, this invention optimizes the connection relationships and interactions between various components, making the operation of the entire device more convenient. For example, the locking mechanism's locking and unlocking design makes the locking and unlocking process of the fixed frame smoother, reducing the complexity of manual intervention. Furthermore, the pressing block design in the pressing device, by precisely matching the contact surface of the fixed frame, further enhances the sealing and stability of the filtration process.

[0012] In summary, this utility model solves the problems existing in the prior art through specific technical solutions, and provides a highly efficient, stable and easy-to-operate filtration device for paper tube glue production, which has significant technical advantages and application value.

Detailed Implementation

[0022] This utility model provides a filtration device for paper tube adhesive production, combined with Figures 1 to 5 The structural diagram and component numbers shown below will be used to describe the specific implementation of the device in detail. The device includes a frame 1, a filtration system, a lifting mechanism, a locking mechanism, and a clamping device. The specific structure and operating principle of each part will be explained in detail below.

[0023] First, the frame 1 serves as the basic support structure for the entire device. A filter hopper 2 is fixed to the frame 1 using nuts and bolts. The bottom of the filter hopper 2 is connected to a discharge pipe 3 via a flange. A valve is installed on the discharge pipe 3 to control material discharge. Two guide rods 10 are symmetrically arranged at the top of the frame 1. An arc-shaped frame 6 is welded to the top of both guide rods 10. A cylinder 7 is mounted on the arc-shaped frame 6, and a piston rod 8 is fixedly connected to the output end of the cylinder 7 to drive the lifting chamber 12 up and down. One side of the lifting chamber 12 is fixedly connected to the end of the piston rod 8 via a connecting block 9, while the other side has a feeding chamber 4. The end of the feeding chamber 4 has a feed inlet 5 for feeding the paper tube adhesive to be filtered into the lifting chamber 12. Both sides of the lifting chamber 12 have integrally formed lifting blocks 11. Guide holes are opened inside the lifting blocks 11, through which the guide rods 10 pass and slide, ensuring the lifting chamber 12 remains stable during up and down movement. The design of the guide rods 10 not only improves the movement accuracy of the lifting chamber 12 but also avoids uneven filtration caused by vibration.

[0024] The main body of the filtration system consists of a filter hopper 2, a fixing frame 13, and a filter screen 14. The fixing frame 13 is detachably fixed to the top of the filter hopper 2, and the filter screen 14 is fixed to the middle of the fixing frame 13 by screws, used to filter impurities in the paper tube adhesive. The connection between the fixing frame 13 and the filter hopper 2 is achieved through a locking mechanism for quick locking and unlocking, facilitating the replacement and cleaning of the filter screen 14. The core components of the locking mechanism include an insert plate 16, an inner groove 21, a lever 15, a locking block 17, a through groove 18, a spring 19, and a connecting plate 20. The insert plate 16 is located at the top of the filter hopper 2, and its shape matches the insertion hole on the fixing frame 13 for fixing the fixing frame 13. An inner groove 21 is formed inside the insert plate 16, and a through groove 18 communicating with the inner groove 21 is formed inside both the filter hopper 2 and the insert plate 16. Two symmetrically arranged levers 15 are slidably connected to the through groove 18. Each lever 15 has a connecting plate 20 welded to it, and one end of the connecting plate 20 is fixedly connected to a locking block 17 with an inclined top. The locking block 17 is slidably connected to the inner groove 21, and a spring 19 is fixedly connected between the locking block 17 and the side wall of the inner groove 21. When the filter screen 14 needs to be replaced or cleaned, the operator only needs to move the lever 15 to disengage the locking block 17 from the inner groove 21, and the fixing frame 13 can be quickly removed for cleaning or replacement. This design significantly reduces the time required to replace the filter screen 14 and improves the convenience of operation.

[0025] The design of the lifting mechanism further optimizes the operational performance of the device. The lifting mechanism consists of a guide rod 10, an arc-shaped frame 6, a cylinder 7, a piston rod 8, a connecting block 9, a lifting chamber 12, and lifting blocks 11. The guide rods 10 are symmetrically arranged on the top of the frame 1, providing guidance for the vertical movement of the lifting chamber 12. The arc-shaped frame 6 is fixed to the top of the guide rod 10 to support the cylinder 7. The output end of the cylinder 7 is fixedly connected to the piston rod 8, and the end of the piston rod 8 is fixedly connected to the lifting chamber 12 via the connecting block 9. Lifting blocks 11 are provided on both sides of the lifting chamber 12. The guide holes inside the lifting blocks 11 are slidably connected to the guide rod 10, ensuring that the lifting chamber 12 remains stable during vertical movement. A feeding chamber 4 is also fixed to one side of the lifting chamber 12, and the end of the feeding chamber 4 has a feeding port 5 for feeding the paper tube adhesive to be filtered into the lifting chamber 12. When cylinder 7 is activated, piston rod 8 drives lifting chamber 12 to descend along guide rod 10 until pressure block 22 presses against fixed frame 13, thus initiating the filtration process. After filtration is completed, cylinder 7 drives lifting chamber 12 to rise, and operator can unlock fixed frame 13 by moving lever 15 to replace or clean filter screen 14.

[0026] The pressing device is an important component of this invention, with the pressing block 22 as its core part. The pressing block 22 is located on the inner wall of the lifting chamber 12 near the bottom, and features a one-piece molded structure. Its shape and dimensions are precisely calculated to ensure a perfect fit with the contact surface of the fixed frame 13. When the lifting chamber 12 descends, the pressing block 22 presses against the fixed frame 13, ensuring the stability of the filtration process. The design of the pressing block 22 not only improves the sealing performance of the device but also avoids uneven filtration caused by poor sealing. Furthermore, the pressing block 22 is made of high-strength, wear-resistant material, ensuring stable performance over long-term use.

[0027] The working principle of this utility model is as follows: S1, the paper tube adhesive to be filtered is fed into the lifting chamber 12 through the feed port 5; S2, the cylinder 7 is activated, and the cylinder 7 drives the piston rod 8 to lower the lifting chamber 12 along the guide rod 10 until the pressure block 22 presses against the fixing frame 13; S3, the paper tube adhesive is filtered through the filter screen 14 and discharged through the discharge pipe 3; S4, when the filter screen 14 needs to be replaced or cleaned, the cylinder 7 drives the lifting chamber 12 to rise, and the operator moves the lever 15 to disengage the locking block 17 from the inner groove 21, and removes the fixing frame 13 for cleaning or replacement. This series of operations is simple and efficient, and can significantly improve the filtration efficiency and quality in the paper tube adhesive production process.

[0028] The technical advantages of this invention are reflected in several aspects. First, the cooperation between the filter screen 14 and the pressing device achieves efficient and stable filtration, significantly improving the quality of the paper tube adhesive. Second, the use of a lifting mechanism and locking mechanism enables quick replacement and cleaning of the filter screen 14, reducing maintenance time. Third, the design of the guide rod 10 and the lifting block 11 ensures the smooth movement of the lifting chamber 12, avoiding uneven filtration caused by vibration. Finally, the entire device has a simple structure, is easy to manufacture and maintain, and is suitable for various paper tube adhesive production scenarios.

[0029] Of particular note is the design of the locking block 17 and spring 19 in the locking mechanism, which makes the locking and unlocking process of the fixed frame 13 smoother and reduces the complexity of manual intervention. Furthermore, the design of the pressure block 22 in the clamping device, by precisely matching the contact surface of the fixed frame 13, further improves the sealing and stability of the filtration process. These detailed designs not only demonstrate the technical advantages of this invention but also provide a solid technical guarantee for its practical application.

[0030] In summary, this utility model solves the problems existing in the prior art through specific technical solutions, providing a highly efficient, stable, and easy-to-operate filtration device for paper tube glue production. From component design to overall structural optimization and the improvement of operating principles, this utility model fully considers the needs of practical application scenarios, demonstrating significant technical advantages and application value.
