Description

Technical Field

[0001] This utility model belongs to the field of cloth bag processing technology, specifically a cloth bag processing traction frame. Background Technology

[0002] The bag processing traction frame is an auxiliary device used in automated bag production lines. It is mainly used to stabilize and position bag materials, ensuring flatness and precision during processing. It is suitable for the continuous and efficient production of various types of bags such as environmental protection bags, packaging bags, and filter bags, significantly improving processing quality and efficiency.

[0003] In existing technologies, cloth bags typically require traction and sealing during use, which necessitates processing with mechanical equipment. Traction clamping devices are commonly used, and their applications are quite widespread. These devices typically use a conveyor belt to feed a large number of cloth bags into an upper clamp, where a vibrating clamp performs the sealing operation. This device usually consists of a frame, guide rollers, a tension adjustment mechanism, a drive motor, and a control system. The motor drives the guide rollers to rotate at a uniform speed, working in conjunction with an adjustable tension device to maintain even fabric feeding, preventing wrinkles or deviations. It can achieve automatic correction and speed matching. The lower conveyor belt assists in completing the traction and clamping operation of the cloth bags, thus completing the sealing process.

[0004] In current technology, traction clamping devices on the market are usually operated by a motor installed on the bottom side. The motor drives the guide roller to rotate at a uniform speed, and an adjustable tension device keeps the fabric evenly fed, avoiding wrinkles or deviation. It can achieve automatic correction and speed matching. With the cooperation of the clamping device above, the traction clamping operation of the cloth bag is completed. However, during the traction clamping process of the cloth bag, after being subjected to force for a long time, the ends of the clamps often loosen, and the gap between the two sides of the clamps will gradually increase, affecting the processing quality and requiring secondary processing, thus affecting work efficiency. Therefore, a cloth bag processing traction frame is proposed to address the above problems. Utility Model Content

[0009] Preferably, an anti-rotation plate is installed in the middle of the gripping rod, the bottom of the anti-rotation plate is connected to the mounting plate, an adapter is installed at the top of the gripping rod, and a middle stop is installed on one side of the gripping rod. When a large number of cloth bags are fed into the end of the clamp via the conveyor belt, the miniature cylinder mounted on the outside of the mounting plate will extend and retract with the opening and closing of the clamp.

[0010] Preferably, a heightening block is installed on the bottom inner wall of the assembly plate, a pitch drive is mounted on the surface of the heightening block, and a circular locking buckle is installed in the slot of the pitch drive.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-5 As shown, a bag processing traction frame includes an outer fixing plate 2. Guide shafts 7 are mounted through both sides of the outer fixing plate 2. The ends of the guide shafts 7 are connected to the outer fixing plate 2 via shaft seats 6. Slide rails 8 are installed on the inner wall surface of the outer fixing plate 2. Multiple sets of sliders 9 are mounted on the surface of the slide rails 8. An mounting plate 10 is mounted on the side of the outer fixing plate 2. A miniature cylinder 15 is mounted on the surface of the mounting plate 10. The miniature cylinder 15 is connected to the mounting plate 10 via a cylinder locking seat 14. A locking buckle 16 is installed in the middle of the miniature cylinder 15, and a pin 13 is installed at the end of the locking buckle 16. A cylinder rod 17 is assembled at the end of the miniature cylinder 15, and a floating joint 18 is assembled at the end of the cylinder rod 17. A floating locking block 11 is installed at the end of the floating joint 18. An assembly block 12 is installed in the middle of the mounting plate 10. An assembly plate 26 is installed on the surface of the slider 9. Multiple sets of fixing plates 25 are installed on the surface of the assembly plate 26. A gripping connecting rod 4 is assembled in the middle of the fixing plate 25.

[0017] In current technology, traction clamping devices on the market typically operate using a motor mounted on the bottom side. The motor drives guide rollers to rotate at a uniform speed, working in conjunction with an adjustable tension device to maintain even fabric feeding, preventing wrinkles or shifting. This allows for automatic correction and speed matching. The clamping device above then assists in the traction and clamping of the fabric bag. However, during the traction and clamping process, after prolonged stress, the ends of the clamps often loosen, causing the clamping gap to gradually widen, affecting processing quality and requiring secondary processing, thus impacting work efficiency. Therefore, to address the aforementioned problem, a bag processing traction frame is proposed. During the bag traction, clamping, and sealing operation, the frame operates through miniature cylinders 15 on both sides. The miniature cylinders 15 drive the air rods 17 at the ends to extend and retract, which in turn drives the floating joints 18 installed at the ends to move, thereby causing the floating locking blocks 11 to move synchronously. The middle part of the floating locking blocks 11 is connected to the outer fixing plate 2. When the floating locking blocks 11 move, they drive the outer fixing plate 2 to move synchronously. The outer fixing plate 2 drives the internal device to perform the bag clamping operation through the guide shaft 7.

[0018] Furthermore, a buffer spring 24 is fitted to the circumferential surface of one end of the gripping rod 4, and a washer 21 is installed on the contact surface between the buffer spring 24 and the fixing plate 25. A nut 20 is installed at the end of the gripping rod 4. An anti-rotation plate 23 is installed in the middle of the gripping rod 4, and the bottom of the anti-rotation plate 23 is connected to the assembly plate 26. An adapter 3 is installed at the top of the gripping rod 4, and a middle stop block 22 is installed on one side of the gripping rod 4. A heightening block 27 is installed on the bottom inner wall of the assembly plate 26, and a pitch-changing drive 19 is fitted on the surface of the heightening block 27. A circular locking buckle 28 is installed in the slot of the pitch-changing drive 19. The variable pitch drive 19 is equipped with an equidistant pull plate 29, and a clamping plate 5 is installed on the inner wall of the equidistant pull plate 29. The equidistant pull plate 29 is connected to a flat pad 31 through a movable connecting rod 30. A bumper plate 1 is installed on the outer side of the flat pad 31, and an equidistant stop block 32 is installed at the connection between the flat pad 31 and the equidistant pull plate 29.

[0019] During operation, when a large number of cloth bags are fed into the middle of the clamping device via the conveyor belt, the end grippers are connected to the device via the gripping rod 4. The grippers can be adjusted laterally via the slide rail 8 installed on the inner wall of the outer fixing plate 2. When the slider 9 on the surface of the slide rail 8 moves, it will drive the transmission structure in the middle to move synchronously, thereby driving the clamping plate 5 below to adjust its position synchronously, thus completing the clamping and sealing operation of the cloth bags and completing the overall traction and clamping operation of the cloth bags.

[0020] Working principle: In current technology, traction clamping devices on the market typically operate using a motor mounted on the bottom side. The motor drives the guide rollers to rotate at a uniform speed, working in conjunction with an adjustable tension device to maintain even fabric feeding, preventing wrinkles or deviations. Automatic correction and speed matching are achieved. This is achieved through the upper clamping device, completing the traction and clamping operation of the fabric bag. However, during the traction and clamping process, the ends of the clamps often loosen after prolonged operation and stress, causing the clamping gap to gradually increase, affecting processing quality and requiring secondary processing, thus impacting work efficiency. Therefore, to address these issues, a fabric bag processing traction frame is proposed. During the traction, clamping, and sealing operation of the fabric bag, miniature cylinders 15 on both sides operate, driving the extension and retraction of the end-mounted air rods 17. The floating joint 18 installed at the end is moved by the air spring 17, which in turn moves the floating locking block 11 synchronously. The middle part of the floating locking block 11 is connected to the outer fixing plate 2. When the floating locking block 11 moves, it will drive the outer fixing plate 2 to move synchronously. The outer fixing plate 2 drives the internal device to perform bag clamping operation through the guide shaft 7. When a large number of bags are fed into the middle of the clamping device by the conveyor belt, the end grippers are connected to the device through the gripping rod 4. The grippers can be adjusted laterally through the slide rail 8 installed on the inner wall of the outer fixing plate 2. When the slider 9 on the surface of the slide rail 8 moves, it will drive the transmission structure in the middle to move synchronously, which will then drive the clamping plate 5 below to adjust synchronously, thereby completing the clamping and sealing operation of the bag and completing the overall traction and clamping operation of the bag.
