Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and in particular to a pressing device for woven bag processing. Background Technology

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastic materials such as polyethylene and polypropylene. Weave density refers to the number of warp and weft yarns within a 100mm x 100mm woven fabric.

[0003] A search of existing Chinese patents revealed a quilting machine selvage positioning device (Publication No.: CN215103891U), which includes an auxiliary mechanism, a main body of the quilting machine selvage positioning device, and a positioning device. The auxiliary mechanism houses the main body of the quilting machine selvage positioning device, and the positioning device is located at the bottom of the auxiliary mechanism. The auxiliary mechanism includes a load-bearing plate, with support rods fixedly installed on both sides of the top of the load-bearing plate. A horizontal plate is fixedly installed between the opposite sides of the two support rods. The positioning device includes an electric push rod, with a first clamping plate fixedly installed at the output end of the electric push rod. A telescopic rod is fixedly installed at the bottom of the horizontal plate, and a second clamping plate is fixedly installed at the bottom of the telescopic rod. Two stabilizing rods are fixedly installed at the top of the load-bearing plate, between the two support rods. This quilting machine selvage positioning device effectively achieves positioning, preventing wrinkles in the woven bags and thus affecting the production quality of the woven bags.

[0004] While the aforementioned Chinese patent achieves effective positioning and can prevent wrinkles in woven bags, thus avoiding issues with production quality, it lacks an effective bag-collecting component. This makes the positioning component unsuitable for producing longer woven bags, which require stacking around the clamping component, hindering production and increasing the likelihood of wrinkles and dirt accumulation, negatively impacting subsequent production and sales. Therefore, it is necessary to invent a pressing device for woven bag processing to address these problems. Utility Model Content

[0008] Preferably, the top of the telescopic cylinder is threaded with multiple sets of mounting bolts, which are arranged in a rectangular pattern on the top of the telescopic cylinder.

[0009] Preferably, a T-shaped slider is fixedly connected to one side of the movable clamping block, and two sets of T-shaped grooves are provided on the inner side of the structural plate, with the two sets of T-shaped grooves being symmetrically distributed on the inner side of the structural plate.

[0010] Preferably, a plurality of pressure springs are fixedly connected to one side of the pressure rod, and the plurality of pressure springs are linearly distributed on one side of the pressure rod.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] This utility model provides, for example Figure 1-4 The illustrated edge-pressing device for woven bag processing includes a work platform 1. Two sets of structural plates 2 are fixedly connected to the top of the work platform 1, symmetrically distributed on the top of the work platform 1. The two sets of structural plates 2 provide support for the equipment above. Telescopic cylinders 6 are installed on the top of the structural plates 2, providing pressure for the clamping function of the device. Telescopic rods 7 are installed at the bottom of the telescopic cylinders 6, serving as the main telescopic component of the telescopic cylinders 6. Two sets of take-up and release rollers 11 are movably connected to the outer side of the work platform 1, symmetrically distributed on the outer side of the work platform 1. The two sets of take-up and release rollers 11 serve as the main storage component of the device. Two sets of bearing seats 12 are installed on both sides of the take-up and release rollers 11. 2. The take-up and release rollers 11 are symmetrically distributed on both sides. Two sets of bearing seats 12 provide movable support for the take-up and release rollers 11. The outer side of the take-up and release rollers 11 is provided with positioning grooves 13. The inside of the positioning grooves 13 is movably connected to the pressing rods 14. The pressing rods 14 are the components for the take-up and release rollers 11 to clamp the woven bags. One side of the bearing seat 12 is movably inserted with a limiting bolt 16. Two sets of limiting slots 17 are provided at both ends of the take-up and release rollers 11. The two sets of limiting slots 17 are symmetrically distributed at both ends of the take-up and release rollers 11. The limiting bolts 16 can be movably inserted into the limiting slots 17. The connection between the protrusion on the outer side of the limiting bolts 16 and the groove on the inner wall of the limiting slots 17 can restrict the take-up and release rollers 11, thereby preventing them from rotating and causing poor storage effect.

[0024] Multiple sets of rubber clamping seats 3 are fixedly connected to the top of the working platform 1. The multiple sets of rubber clamping seats 3 are rectangularly distributed on the top of the working platform 1. Two sets of movable clamping blocks 4 are movably connected to the bottom of the structural plate 2. The two sets of movable clamping blocks 4 are symmetrically distributed on the bottom of the structural plate 2. A movable plate 5 is fixedly connected to one side of the movable clamping block 4. The multiple sets of rubber clamping seats 3 and the movable clamping blocks 4 are all made of rubber, which can effectively improve the clamping effect of the device. The use of the movable plate 5 provides a connection between the two sets of movable clamping blocks 4, so that the two sets of movable clamping blocks 4 can move synchronously, further ensuring the clamping effect of the device.

[0025] The top threaded connection of the telescopic cylinder 6 has multiple sets of mounting bolts 8, which are arranged in a rectangular shape on the top of the telescopic cylinder 6. The multiple sets of mounting bolts 8 can be threaded to the threaded holes on the top of the structural plate 2, thereby realizing the installation connection of the telescopic cylinder 6. This connection provides a firm fixation effect and effectively reduces the noise generated by the telescopic cylinder 6 during operation.

[0026] A T-shaped slider 9 is fixedly connected to one side of the movable clamping block 4. Two sets of T-shaped grooves 10 are provided on the inner side of the structural plate 2. The two sets of T-shaped grooves 10 are symmetrically distributed on the inner side of the structural plate 2. The T-shaped slider 9 can be movably connected to the T-shaped grooves 10, thereby limiting the movable clamping block 4 and preventing its position from shifting, which would result in poor clamping effect.

[0027] Multiple sets of pressure springs 15 are fixedly connected to one side of the pressure rod 14. The multiple sets of pressure springs 15 are linearly distributed on one side of the pressure rod 14. The rebound force of the multiple sets of pressure springs 15 can be applied to the pressure rod 14, thereby pressing and fixing one end of the woven bag, and thus realizing the storage function of the take-up and take-down roller 11 on the woven bag.

[0028] The outer wall of the limiting bolt 16 is movably connected to a movable threaded sleeve 18, and one side of the bearing seat 12 is fixedly connected to a fixed threaded seat 19. The outer wall of the limiting bolt 16 is provided with a limiting groove 20. The inner threaded groove of the movable threaded sleeve 18 can be threadedly connected to the fixed threaded seat 19, thereby realizing the connection between the limiting bolt 16 and the bearing seat 12 and preventing the limiting bolt 16 from falling off. The limiting groove 20 can be movably connected to the limiting edge on the outside of the movable threaded sleeve 18, thereby realizing the rotation function of the movable threaded sleeve 18 while also limiting the movable threaded sleeve 18.

[0029] Multiple sets of bearing balls 21 are movably connected inside the bearing housing 12. The multiple sets of bearing balls 21 are arranged in a ring inside the bearing housing 12. The use of multiple sets of bearing balls 21 can effectively reduce the frictional resistance at the connection between the take-up roller 11 and the bearing housing 12, thereby effectively improving the rotational efficiency of the take-up roller 11 and thus improving the storage efficiency of the device.

[0030] Working principle: After connecting the device to the quilting machine head, the user places the woven bag on the work platform 1 and opens the pressure rod 14 in the positioning groove 13 of the take-up and release roller 11. Then, the user inserts both ends of the woven bag into the positioning groove 13 and releases the pressure rod 14. When the pressure rod 14 is released, the pressure on the multiple pressure springs 15 on its back disappears, and its rebound force pushes the pressure rod 14 back to its original position and clamps the ends of the woven bag. Then, the user rotates the take-up and release roller 11 to take in both ends of the woven bag until the woven bag is taut. Finally, the user inserts the limiting bolt 16 into the limiting slot 17. The limiting take-up roller 11 will no longer be able to rotate. Then, the user rotates the movable threaded sleeve 18. The movable threaded sleeve 18 rotates in the limiting groove 20 on the outer wall of the limiting plug 16. Through the threaded connection between the movable threaded sleeve 18 and the fixed threaded seat 19, the limiting plug 16 is driven to go deeper into the limiting slot 17 and connected to the limiting plug 16, thereby realizing the storage function of the device. Then, the user powers on the telescopic cylinder 6. When the telescopic cylinder 6 is powered on and started, it will push the two sets of movable clamping blocks 4 down through the telescopic rod 7, thereby pressing and positioning the woven bag, thus realizing the storage and positioning function of a pressing device for woven bag processing.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
