Description

Technical Field

[0001] This utility model relates to the field of cotton production technology, specifically a cotton baling machine. Background Technology

[0002] Cotton baling machines, also known as hydraulic cotton baling machines, feature novel structures, high technology, good rigidity and stability, high automation, beautiful appearance, and energy saving. The machine is top-mounted, ensuring no cotton contamination. Its simple oil circuit makes operation and maintenance convenient and safe. The main pressure cylinder uses a dual-pump oil supply, enabling high-flow-rate, rapid bale formation. It is a new product integrating mechanics, electricity, and hydraulics, reaching international advanced levels. With the continuous production of cotton baling machines, various types of cotton baling machines have emerged, such as a baling machine specifically for cotton production.

[0003] Currently, cotton baling machines on the market mainly focus on improving baling speed. Existing cotton baling machines are mainly composed of a frame, bale box, hydraulic system, and control system. The control system reduces the volume of cotton inside the bale box to facilitate baling. However, existing baling machines use vertical downward compression, resulting in a significantly higher density at the bottom of the cotton bale (average 210 kg / m²) than at the top (average 160 kg / m²), with a density deviation of 25% to 30%. The fiber breakage rate in the high-pressure zone is as high as 15%, affecting the quality of yarn. Therefore, a cotton baling machine that can use vertical counter-compression to reduce the lateral density deviation of the cotton bale and reduce the fiber damage rate is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cotton baling machine that features vertical counter-compression, reducing lateral density deviation of cotton bales and decreasing fiber damage rate. It solves the problem that existing baling machines use vertical downward compression, resulting in a significantly higher density at the bottom of the cotton bale (average 210 kg / m²) than at the top (average 160 kg / m²), with a density deviation of 25% to 30%, and a fiber breakage rate as high as 15% in the high-pressure zone, which affects yarn quality.

[0005] To achieve the above-mentioned purpose of using vertical counter-compression to reduce the lateral density deviation of cotton bales and reduce fiber damage rate, this utility model provides the following technical solution: a baling machine for cotton production, including a baling box, a support fixedly installed on the right side of the baling box, a storage box fixedly installed on the top of the support, and a compression mechanism provided inside the baling box;

[0006] The compression mechanism includes a hydraulic cylinder 1, a cotton pressing plate 1, a hydraulic cylinder 2, a cotton pressing plate 2, an electric telescopic rod 1, a push plate, a movable door, and an electric telescopic rod 2. A hydraulic cylinder 1 is fixedly installed on the top of the packing box, a cotton pressing plate 1 is fixedly installed on the bottom of the hydraulic cylinder 1, a hydraulic cylinder 2 is fixedly installed inside the packing box, a cotton pressing plate 2 is fixedly installed on the top of the hydraulic cylinder 2, an electric telescopic rod 1 is fixedly installed inside the packing box, a push plate is fixedly installed on the left side of the electric telescopic rod 1, a movable door is hinged to the left side of the packing box, and an electric telescopic rod 2 is fixedly installed inside the packing box.

[0007] Furthermore, a collection box is fixedly installed on the left side of the packing box, and an opening is provided on the top of the collection box, which allows fallen cotton balls to enter the collection box for collection.

[0008] Furthermore, a discharge fan is fixedly installed inside the storage box, and the air outlet of the discharge fan is fixedly connected to a feed pipe. The feed pipe is connected to the inside of the packing box. By setting up the discharge fan, cotton can be transported into the inner box of the packing box through the feed pipe.

[0009] Furthermore, a pressure sensor is provided at the bottom of the first pressing plate and a pressure sensor is provided at the top of the second pressing plate. By providing pressure sensors, the PLC controller can adjust the pressure of the first and second hydraulic cylinders according to the pressure.

[0010] Furthermore, an installation plate is fixedly installed on the top of the electric telescopic rod 2, and seven locking posts are welded on the installation plate. The interior of the movable door is provided with locking slots that are compatible with the seven locking posts. By setting the seven locking posts, the movable door can be stably fixed when compressing cotton.

[0011] Furthermore, a PLC controller is installed at the front of the packing box, and the hydraulic cylinder one, hydraulic cylinder two, electric telescopic rod one, electric telescopic rod two, discharge fan and pressure sensor are all electrically connected to the PLC controller through wires.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This cotton baling machine, through the installation of a compression mechanism, operates by activating the PLC controller, which starts the discharge fan to draw cotton into the baling box. Hydraulic cylinder one then presses the cotton down on the pressing plate for pre-compression. Hydraulic cylinder two then performs a second compression upwards, holding the pressure for five minutes before returning to its original position. Next, electric telescopic rod two retracts, while electric telescopic rod one extends, pushing the cotton bale to the left and opening the hinged door, allowing the cotton bale to fall into the collection box. The door then returns to its original position by gravity, and the locking pins on the mounting plate re-engage. This compression mechanism allows for vertical counter-compression, reducing lateral density deviation in the cotton bale and minimizing fiber damage. Attached Figure Description

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 protection scope of the present utility model.

[0020] Please see Figure 1-4 In this embodiment, a cotton baling machine includes a baling box 1, a support 2 fixedly installed on the right side of the baling box 1, a storage box 3 fixedly installed on the top of the support 2, and a compression mechanism 4 provided inside the baling box 1.

[0021] The compression mechanism 4 includes a hydraulic cylinder 401, a pressing plate 402, a hydraulic cylinder 403, a pressing plate 404, an electric telescopic rod 405, a push plate 406, a movable door 407, and an electric telescopic rod 408. The top of the packing box 1 is fixedly installed with the hydraulic cylinder 401, and the bottom of the hydraulic cylinder 401 is fixedly installed with the pressing plate 402. The inside of the packing box 1 is fixedly installed with the hydraulic cylinder 403, and the top of the hydraulic cylinder 403 is fixedly installed with the pressing plate 404. The inside of the packing box 1 is fixedly installed with the electric telescopic rod 405, and the left side of the electric telescopic rod 405 is fixedly installed with the push plate 406. The left side of the packing box 1 is hinged with the movable door 407. The inside of the packing box 1 is fixedly installed with the electric telescopic rod 408, and there are two electric telescopic rods 408.

[0022] In the implementation of the case, a discharge fan 6 is fixedly installed inside the storage box 3. The air outlet of the discharge fan 6 is fixedly connected to the feed pipe, which is connected to the inside of the packing box 1. By setting up the discharge fan 6, cotton can be transported into the inner box of the packing box 1 through the feed pipe.

[0023] In the implementation case, pressure sensors 7 are installed at the bottom of pressure plate 1 (402) and at the top of pressure plate 2 (404). These pressure sensors 7 allow the PLC controller 9 to adjust the pressure of hydraulic cylinders 1 (401) and 2 (403) based on the pressure readings. The PLC controller 9 can communicate with and adjust the pressure sensors 7. Specifically, the PLC receives the analog signal output from the pressure sensor 7 via an A / D module, converts it into a digital signal for processing, and then outputs corresponding control signals via a D / A module to adjust the actuators (such as frequency converters and solenoid valves), thereby regulating the pressure.

[0024] In the implementation of the case, hydraulic cylinder 401 and hydraulic cylinder 403 are double-acting multi-stage hydraulic cylinders. The hydraulic circuit is equipped with corresponding key components, such as accumulators, pressure compensation valves and proportional directional valves.

[0025] In the implementation of this case, the PLC controller 9 is electrically connected to all electronic components in this patent via wires, thereby controlling all electronic components in this patent by operating the PLC controller 9.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) When the baling machine is working, the discharge fan 6 is started by turning on the PLC controller 9 to draw cotton into the baling box 1;

[0028] 2) Then, hydraulic cylinder 401 is opened to press down the cotton pressing plate 402 to pre-press the cotton;

[0029] 3) Restart hydraulic cylinder 403 to compress upwards for a second time, hold the pressure for five minutes, and then return to the original position. Then start electric telescopic rod 408 to retract.

[0030] 4) Finally, the electric telescopic rod 405 extends, pushing the cotton ball to the left and opening the hinged movable door 407, causing the cotton ball to fall into the collection box 5. The movable door 407 returns to its original position by gravity, and the locking pin on the mounting plate 8 re-engages.

[0031] In summary, this cotton baling machine, by setting up a compression mechanism 4, when the baling machine is working, by turning on the PLC controller 9, the discharge fan 6 starts to draw cotton into the baling box 1. The hydraulic cylinder 401 opens to press down the cotton on the pressing plate 402 for pre-compression. Then, the hydraulic cylinder 403 is activated to perform a second compression upwards, and after holding the pressure for five minutes, it returns to its original position. Then, the electric telescopic rod 408 is activated to retract, and the electric telescopic rod 405 extends, pushing the cotton ball to the left and opening the hinged movable door 407, allowing the cotton ball to fall into the collection box 5. The movable door 407 returns to its original position by gravity, and the locking pin on the mounting plate 8 re-engages. This compression mechanism 4 can use vertical counter-compression to reduce the lateral density deviation of the cotton bale and reduce the fiber damage rate.
