[0004] The purpose of the present invention is to loosen the compacted cotton to make the cotton fluffy again, and a highly efficient cotton bale loosening device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Referring to Figures 1 - 10 , an efficient cotton bale opening device includes a frame 6, and also includes a support frame 1 and a support shaft 2 fixedly connected to one end of the support frame 1. The support shaft 2 is rotatably connected to the frame 6, and a power assembly capable of rotating the support frame 1 around the axis of the support shaft 2 is installed between the support shaft 2 and the frame 6. The support frame 1 has at least two arc-shaped support parts, and a number of actively rotating opening rollers 5 are installed on each arc-shaped support part. For example, a plurality of opening rollers 5 are driven by a chain or a gear, and then one or more rotating motors drive the opening rollers 5 to rotate. The cotton bale is gradually peeled off by the hook teeth on the outer circumference of the opening roller 5. A number of opening rollers 5 form a curved surface structure along the bending shape of the arc-shaped support part. Define two adjacent arc-shaped support parts as the first curvature part 3 and the second curvature part 4 respectively. The first curvature part 3 is close to the support shaft 2, and the curvature of the first curvature part 3 is greater than the curvature of the second curvature part 4.

[0030] During operation, the cotton bale is initially placed on the second curvature part 4 with a smaller curvature (such asFigure 1 or Figure 7 ) At this time, the outer diameter of the cotton bale is relatively large, and the opening roller 5 on the second curvature portion 4 wraps the cotton compressed bale. The opening roller 5 rotates actively, gradually peeling and loosening the outer circumference of the cotton bale, so that the diameter of the cotton bale gradually decreases. As the volume of the cotton bale shrinks, the power assembly drives the support frame 1 to slowly rotate around the support shaft 2, so that the cotton compressed bale gradually transitions from the second curvature portion 4 to the first curvature portion 3 with a larger curvature, thereby maintaining the tight wrapping of the opening roller 5 on the surface of the cotton bale and realizing continuous and efficient opening processing.

[0031] By setting a plurality of arc-shaped support portions with gradually changing curvatures and combining with the rotation adjustment of the support frame 1, the present device enables the cotton compressed bale to form a matching covering contact with the opening roller 5 at different diameter stages, improving the working efficiency of the opening roller and the loosening quality of the cotton. It is expected to solve the problems of uneven opening or low efficiency commonly existing in the industry.

[0032] A rotating mechanism is installed on the support frame 1, and the rotating mechanism can make the cotton compressed bale rotate on the support frame 1. The cylindrical cotton compressed bale rotates on its own axis while being peeled by the opening roller 5 on one side of the arc-shaped support portion, so that the outer circumference of the cotton compressed bale is evenly peeled.

[0033] The rotating mechanism includes a plurality of support rollers 10, the support rollers 10 are rotatably connected to the support frame 1, the opening roller 5 includes a roller body and hook teeth located on the outer circumference of the roller body. During operation, the cotton compressed bale is supported on the support rollers 10, and at least part of the hook teeth on the outer circumference of the opening roller 5 can hook the cotton compressed bale.

[0034] During operation, the cotton compressed bale is placed on a plurality of support rollers 10 on the support frame 1, and the rotation of the support rollers 10 drives the cotton bale to rotate on its own axis. At the same time, the opening roller 5 continuously rotates, and the hook teeth arranged on the outer circumference of its roller body contact and hook and tear the outer layer of the cotton compressed bale, realizing uniform peeling of the cotton layer on the surface of the cotton bale. The cotton bale rotates on its own axis while contacting the opening roller 5 on the support frame 1, so that the entire cylindrical surface can be continuously and evenly opened. By setting a rotating mechanism that can realize self-rotation, the present structure enables the cotton compressed bale to realize rotary opening on the support frame 1, effectively avoiding the problems of repeated processing or unprocessed in local areas and improving the opening uniformity.

[0035] The supporting roller 10 is drivingly connected to the first rotating motor. An annular belt 11 is installed between several supporting rollers 10, and the cotton bale is supported on the belt 11. The cotton bale is placed on the belt 11. As the supporting roller 10 rotates, the belt 11 moves accordingly, thereby driving the cotton bale to achieve stable self-rotation on the support frame 1. During this process, the hook teeth of the loosening roller 5 contact and strip the outer layer of the cotton bale to achieve continuous loosening operation. By setting the belt 11, the contact area between the cotton bale and the rotating mechanism is significantly increased, the stability of the cotton bale self-rotation and the transmission efficiency are improved, and the situations of slipping or uneven rotation are avoided.

[0036] Reference Figure 6 , as a spatial distribution mode, the support frame 1 has several first spaces 12 distributed at intervals, and there is a second space 13 between adjacent first spaces 12. The loosening roller 5 is installed in the first space 12, and the supporting roller 10 is installed in the second space 13.

[0037] As an implementation manner of the power assembly, the power assembly includes a torsion spring. The torsion spring is installed between the support shaft 2 and the frame 6. As the weight of the cotton bale decreases, the torsion spring can make the support frame 1 rotate around the axis of the support shaft 2 and make the cotton bale move from the second curvature part 4 to the first curvature part 3. The power assembly adopts a torsion spring structure and is installed between the support shaft 2 and the frame 6. In the initial state, due to the large weight of the cotton bale, the support frame 1 is kept at the position of the second curvature part 4 under the action of gravity. As the loosening roller 5 continuously strips the cotton, the weight of the compressed bale gradually decreases, especially the force at the end of the support frame 1 far from the support shaft 2 also decreases accordingly. At this time, the elastic potential energy stored in the torsion spring is gradually released, driving the support frame 1 to slowly rotate around the axis of the support shaft 2, thereby pushing the cotton bale to move in the direction of the first curvature part 3. This implementation manner automatically adjusts the rotation of the support frame 1 through the torsion spring, enabling the cotton bale to smoothly transition from the second curvature part 4 to the first curvature part 3 adaptively during the weight change process, and avoiding the complexity of an additional electronic control system. This structure not only simplifies the structure and reduces the energy consumption, but also improves the adaptability of the device to different cotton bale states and the continuity of loosening, effectively ensuring the wrapping property and working efficiency between the loosening roller 5 and the cotton bale.

[0038] As an implementation manner of the power assembly, reference Figure 5 , the power assembly includes a tension spring 7 and an extension rod 8. The extension rod 8 is arranged radially along the support shaft 2 and the two are fixedly connected. The tension spring 7 is installed between the end of the extension rod 8 and the frame 6. As the weight of the cotton bale decreases, the tension spring 7 can pull the extension rod 8 to make the support frame 1 rotate around the axis of the support shaft 2 and make the cotton bale move from the second curvature part 4 to the first curvature part 3.

[0039] The power assembly adopts a structural form in which a tension spring 7 cooperates with an extension rod 8. The extension rod 8 is arranged radially along the support shaft 2 and fixedly connected thereto. The tension spring 7 is connected between the end of the extension rod 8 and the frame 6 to form an elastic system with a traction effect. In the initial state, the weight of the cotton compression bale is relatively large, and the support frame 1 stays at the position of the second curvature part 4 under the action of gravity. As the opening roller 5 gradually strips the cotton, the weight of the bale decreases, the resistance on the extension rod 8 decreases, and the tension spring 7 gradually pulls the extension rod 8, thereby driving the support frame 1 to slowly rotate around the axis of the support shaft 2, realizing the automatic transition of the cotton compression bale to the first curvature part 3. In this embodiment, by setting the tension spring 7 to drive the extension rod 8, a cotton bale displacement adjustment mechanism with a simple structure and sensitive response is realized. This device utilizes the change in force balance caused by the change in the weight of the cotton bale to realize the adaptive control of the rotation angle of the support frame 1 without additional sensors or drive systems. During the process of the cotton compression bale gradually becoming lighter, it can naturally move towards the area with a larger curvature, thereby continuously maintaining the wrapping effect of the opening roller 5 and ensuring the efficiency and uniformity of the cotton loosening process.

[0040] As an embodiment of the power assembly, the power assembly includes a power telescopic cylinder and an extension rod 8. The extension rod 8 is arranged radially along the support shaft 2 and fixedly connected to it. Both ends of the power telescopic cylinder are movably installed between the end of the extension rod 8 and the frame 6. When the power telescopic cylinder shortens, it can pull the extension rod 8 to make the support frame 1 rotate around the axis of the support shaft 2 and make the cotton compression bale move from the second curvature part 4 to the first curvature part 3. In this embodiment, the power assembly adopts a combined structure of a power telescopic cylinder and an extension rod 8. The extension rod 8 is arranged radially along the support shaft 2 and fixedly connected to it. One end of the power telescopic cylinder is connected to the end of the extension rod 8, and the other end is connected to the frame 6, forming a controllable driving connection relationship. During the working process, when it is necessary to promote the cotton loosening process, the power telescopic cylinder actively shortens, driving the extension rod 8 to move towards the frame 6, thereby pushing the support frame 1 to rotate around the axis of the support shaft 2, realizing the movement of the cotton compression bale from the second curvature part 4 to the first curvature part 3. This structure realizes the active control of the rotation of the support frame 1 through the power telescopic cylinder. Compared with the elastic element driving form, it has the characteristics of fast response and high adjustment accuracy. This method can flexibly adjust the position of the cotton bale according to the actual processing rhythm or control logic, ensuring that the opening roller 5 and the cotton compression bale always maintain good contact, thereby effectively improving the uniformity and processing efficiency of cotton loosening. At the same time, active control is beneficial to realizing an intelligent cotton loosening process and has stronger compatibility with an automated production line.

[0041] The power assembly includes a second rotating motor. The power output shaft of the second rotating motor is in transmission connection with the support shaft 2. The second rotating motor can drive the support shaft 2 to rotate and make the cotton bale move from the second curvature part 4 to the first curvature part 3. In this embodiment, the power assembly uses the second rotating motor as the driving source, and the power output shaft of the second rotating motor is in transmission connection with the support shaft 2. During the working process, the second rotating motor drives the support shaft 2 to rotate through the power output shaft, and then makes the support frame 1 rotate around the axis of the support shaft 2, so as to push the cotton bale to gradually transition from the second curvature part 4 to the first curvature part 3, realizing continuous loosening operation.

[0042] Reference Figure 5 , the cotton loosening device includes a housing 9. The housing 9 is fixed to the support frame 1. The housing 9 surrounds the outer peripheral side of the support frame 1 and the upper part of the housing 9 is open. The housing 9 is connected with a negative pressure cotton sucking device. The outer peripheral side of the support frame 1 is wrapped by the housing 9, and the upper side is open, which is convenient for placing the cotton bale on the arc-shaped support part of the support frame 1 from the open position. During the cotton loosening process, the peeled cotton fluffs are sent to the next process by the negative pressure cotton sucking device.

[0043] When a sufficient number of arc-shaped support parts are provided, reference can be made to Figures 7 - 10 , the whole support frame presents a state similar to an Archimedean spiral, so that the cotton bale can smoothly transition from the second curvature part 4 to the first curvature part 3.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes to obtain technical solutions, concepts, and designs, which should all be covered by the protection scope of the present invention.
