Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton production and processing technology, specifically a cotton bale bag and binding device. Background Technology
[0002] To facilitate the transportation and storage of cotton, it is necessary to bag and bundle the cotton after processing. Using packaging bags to package the compressed cotton bales not only prevents the cotton from being contaminated, but also makes it easier to stack the cotton bales using a palletizer. Bundling the packaged cotton bales with a bundling device can further improve the overall structural stability of the cotton bales, ensuring that the cotton bales remain stable and reliable during subsequent transportation and stacking.
[0003] Existing cotton bale bagging and binding devices can only perform simple bagging and binding of cotton, failing to further compress the corners of the compressed cotton bales. Because the cotton bales are simply compressed into rectangles, some loose cotton remains at the corners, affecting the smoothness of the bagging process and making the cotton bales prone to jamming. Using larger bags not only increases the cost of bagging and binding but also results in overly loose bales, impacting the reliability of subsequent transportation. Therefore, we propose a cotton bale bagging and binding device to solve these problems. Utility Model Content
[0004] To address the above technical problems, this utility model provides a cotton bale covering and binding device to solve the problems of insufficient smoothness of cotton bale covering, inability to further compress the edges and corners of the cotton bale, making the cotton bale easily jammed by the bag body, and using a larger bag body for covering, which not only increases the cost of covering and binding the cotton bale, but also makes the cotton bale too loose after covering, affecting the reliability of subsequent transportation of the cotton bale.
[0005] To solve the above-mentioned technical problems, the present invention provides a cotton bale bagging and binding device, comprising a bagging machine, a heat-sealing machine on the right side of the bagging machine, a binding machine on the right side of the heat-sealing machine, a base plate on the left side of the bagging machine, four positioning frames fixedly connected to the right side of the base plate, each positioning frame having an inclined fixing frame fixedly connected to it, and a squeezing roller rotatably connected to the inner side of the fixing frame, forming a shaping opening between the four squeezing rollers for rectangular cotton bales to pass through. A placement platform is fixedly connected to the left side of the base plate, a support frame is fixedly connected to the left side of the placement platform, an electric push rod is fixedly connected to the inner wall of the support frame, and a push plate is fixedly connected to the telescopic end of the electric push rod.
[0006] Furthermore, both ends of the fixed frame are rotatably connected to screws, and each screw is threaded with a sliding seat. A rotating column is rotatably connected inside the sliding seat. Both ends of the extrusion roller are fixedly connected to the rotating columns located on both sides. One end of each screw is fixedly connected to a first bevel gear. Rotating rods are rotatably arranged on the outside of the fixed frame. Two second bevel gears are fixedly connected to both ends of each rotating rod. The second bevel gears mesh with the corresponding first bevel gears. Worm gears are fixedly connected to each rotating rod. A worm gear meshing with the worm gear is rotatably connected to the fixed frame. A rotating head is fixedly connected to one end of the worm gear.
[0007] Furthermore, a protective shell is fixedly connected to one side of the fixing frame, the rotating rod is rotatably connected to the inside of the protective shell, one end of the worm gear extends through to the outside of the protective shell, and the rotating head is located outside the protective shell.
[0008] Furthermore, the rotating column is rotatably connected to the sliding seat via an auxiliary bearing that is fixedly embedded in the sliding seat.
[0009] Furthermore, an indicator is fixedly connected to one side of the sliding seat, and scales arranged at equal intervals are fixedly connected to one side of the fixing frame. The indicator is slidably connected inside the fixing frame, and a strip hole is provided at the end of the fixing frame to observe the indicator.
[0010] Furthermore, an auxiliary frame is provided on the right side of the fixed frame, and four auxiliary rollers are rotatably connected to the inner side of the auxiliary frame.
[0011] Furthermore, the bottom surface of the support frame is fixedly connected with reinforcing ribs, and the bottom surface of the reinforcing ribs is fixedly connected to the upper surface of the base plate.
[0012] This utility model has the following advantages compared with the prior art:
[0013] 1. This utility model, by setting a fixed frame and using four inclined compression rollers, can compress the four rectangular sides of the rectangular cotton bale before it enters the bagging machine. In addition, with the auxiliary frame and four auxiliary rollers, it can ensure the shape of the rectangular cotton bale after the rectangular sides are compressed, making the cotton bale more neat and regular before bagging. It can also compress the free cotton at the corners of the rectangular cotton bale, making it fit the whole cotton bale, and ensuring the smoothness of subsequent bagging.
[0014] 2. This utility model, by setting up a worm gear and rotating rod in conjunction with the transmission of the first and second bevel gears, can simultaneously drive the two sliding seats inside a fixed frame to slide by manually rotating the worm gear and screw without affecting the rotation of the rotating column inside the sliding seat. This allows the spacing between the extrusion rollers to be adjusted by rotating the column, thereby adjusting the extrusion intensity of the rectangular cotton edge corner and further improving the regularity of the cotton edge corner extrusion. At the same time, by setting up indicators and scales, it is easy to observe the adjustment spacing of the extrusion rollers and ensure that the adjustment spacing of all extrusion rollers is the same.

The placement platform 17 is used to place the compressed rectangular cotton bale 21. A support frame 18 is fixedly connected to the left side of the placement platform 17. An electric push rod 19 is fixedly connected to the inner wall of the support frame 18 by bolts. A push plate 20 is fixedly connected to the telescopic end of the electric push rod 19 by bolts. The electric push rod 19 drives the push plate 20 to move, which can push the rectangular cotton bale 21 through the shaping opening formed between the compression rollers 7 and into the bagging machine 1. It should be noted that in this embodiment, the bagging machine 1, the hot melt sealing machine 2, and the binding machine 3 are all existing devices assembled to form a cotton bagging and binding production line. The specific structure of each mature device will not be described in detail in this application. At the same time, the roller conveyor between the devices for material transportation to form a production line is a conventional setting in this field.
[0024] To enable position adjustment of the extrusion rollers 7 and control the size of the forming opening formed by the four extrusion rollers 7, screws 8 are rotatably connected to both the upper and lower ends of the fixed frame 4. Sliding seats 5 are threaded onto both screws 8. An auxiliary bearing 26 is fixedly embedded inside the sliding seat 5. One end of the rotating column 6 is connected to the auxiliary bearing 26. The two ends of the extrusion rollers 7 are fixedly connected to the rotating columns 6 located on both sides. A first bevel gear 9 is fixedly connected to one end of each screw 8. To prevent external dust and impurities from entering the protective shell 27 and affecting the normal rotation of the gear structure, a protective shell 27 is fixedly connected to one side of the fixed frame 4. Rotating rods 10 are rotatably installed on the outside of the fixed frame 4 inside the protective shell 27. Two second bevel gears 11 are fixedly connected to both ends of the rotating rods 10. The second bevel gears 11 mesh with the corresponding first bevel gears 9. Worm gears 12 are fixedly connected to each rotating rod 10. A worm gear 13 that meshes with the worm gear 12 is rotatably connected to the fixed frame 4. One end of the worm gear 13 extends through to the outside of the protective shell 27 and is fixedly connected to a rotating head.
[0025] To facilitate control of the adjustment amount when adjusting the position of the extrusion roller 7 and to ensure that the adjustment amount of all extrusion rollers 7 is consistent, an indicator 24 is fixedly connected to one side of the sliding seat 5, and scale marks 25 are arranged at equal intervals on the outer side of the fixing frame 4. In order to protect the indicator 24, the indicator 24 is slidably connected inside the fixing frame 4, and the end of the fixing frame 4 is provided with a slot for observing the position of the indicator 24.
[0026] An auxiliary frame 14 is provided on the right side of the fixed frame 4. The auxiliary frame 14 is fixedly connected to the left side of the bagging machine 1. The auxiliary frame 14 forms a "U"-shaped structure. Four auxiliary rollers 15 are rotatably connected to the inner side of the auxiliary frame 14 through a rotating shaft and bearings. In order to improve the stability and firmness of the support frame 18 and ensure the stable operation of the device, a reinforcing rib 22 is welded and fixed to the bottom surface of the support frame 18. The lower end of the reinforcing rib 22 is welded and fixed to the upper surface of the base plate 16.
[0027] In this embodiment, a corresponding controller is provided to control the various components of the device. This is a conventional method, and its corresponding electrical control principle will not be described in detail in this article.
[0028] The working principle of this embodiment is as follows:
[0029] In use, first connect the bagging machine 1, hot melt sealing machine 2, strapping machine 3, electric push rod 19, and controller to an external power source. When bagging and strapping cotton bales are required, first place the rectangular cotton bale 21 on the placement platform 17, and then use the power provided by the electric push rod 19 to push the rectangular cotton bale 21 into the space formed by the squeezing roller 7. At this time, utilizing the softness of the cotton itself, combined with friction, as the rectangular cotton bale 21 moves to the left, it can drive the squeezing roller 7 to rotate. At this time, the fixing frame 4, together with the four 45-degree inclined squeezing rollers 7, can push the rectangular cotton bale 21 into the space formed by the squeezing roller 7. Before entering the bagging machine 1, the four rectangular sides of the rectangular cotton bale 21 are squeezed. With the help of the auxiliary frame 14 and four auxiliary rollers 15, the shape of the rectangular cotton bale 21 after squeezing is ensured, making the cotton bale more neat and regular before bagging. By squeezing the free cotton at the corners of the rectangular cotton bale 21, it can fit more closely to the whole cotton bale and will not stick up too much, thus ensuring the smoothness of subsequent bagging of the cotton bale. After the rectangular cotton bale 21 is bagged by the bagging machine 1, it will be sealed by the heat-sealing machine 2, and finally the bagging and binding process of the cotton bale will be completed by the binding machine 3. By manually rotating the rotating head, the worm gear 13 is driven to rotate, which in turn drives the rotating rod 10 to rotate. Then, through the transmission of the first bevel gear 9 and the second bevel gear 11, the two screws 8 in a fixed frame 4 can be driven to rotate synchronously. This allows the sliding seat 5 to drive the extrusion roller 7 to adjust the spacing through the rotating column 6. By adjusting the spacing of the extrusion roller 7, the extrusion intensity of the corners of the rectangular cotton bale 21 can be adjusted, further improving the regular forming effect of the extrusion of the cotton bale corners.
