Description

Technical Field

[0001] This invention relates to the field of cellulose production technology, and in particular to a device for cutting the packing straps of refined cotton. Background Technology

[0002] Refined cotton is a white, fluffy substance made from cotton linters through processes such as alkaline cooking, bleaching, milling to remove water, and air-drying. It has a uniform, loose appearance and is free of impurities such as sawdust and metal. This product is a key raw material for manufacturing nitrocellulose, cellulose acetate, and cellulose ethers (such as CMC and HEC), and is used in numerous industries including food, pharmaceuticals, plastics, and aerospace.

[0003] When refined cotton leaves the factory, it is compacted and packaged, and then tied with strapping. Before the refined cotton pretreatment process, it is necessary to remove the refined cotton from the packaging. The first step is to cut the strapping. Currently, this step is basically done manually, which has problems such as low cutting efficiency and high labor intensity. In addition, when the strapping is cut, the tension generated by the cotton bale is suddenly released, which may injure the operator, posing a certain safety hazard.

[0004] Chinese patent application number CN202411776586.0 discloses an automatic cotton bale opening and feeding device. It uses a dust-collecting cutter to cut the packing strap from the top of the cotton bale. After being cut, the packing strap unfolds to both sides and falls automatically through the gap between the conveyor rollers into a packing strap collection box below. This design has the following problems:

[0005] 1. Even with dust-collecting cutting blades, some debris and smoke will still be generated during cutting and dust collection, which may still affect the purity of nitrocellulose;

[0006] 2. Cutting from the top will cause the packing strap to snap open to both sides, posing a safety hazard to equipment and personnel.

[0007] 3. Due to the weight of the cotton bales, only about 70% of the packing straps will fall into the recycling bins after being cut. The remaining packing straps will still enter the subsequent processing and require manual sorting.

[0008] Therefore, in order to improve production efficiency and fully ensure the personal safety of operators, it is urgent to improve the existing refined cotton bale packing tape cutting device. Summary of the Invention

[0009] Based on the above, the purpose of this invention is to provide a fully automatic refined cotton bag packing strap cutting device, which can effectively solve the above-mentioned problems existing in the current production process and improve production efficiency and safety.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] This application provides a device for cutting the packing straps of refined cotton bales, comprising:

[0012] frame;

[0013] A conveying mechanism, mounted on the frame, is used to convey cotton bales;

[0014] An attitude adjustment mechanism is installed on the frame and located on both sides of the conveying mechanism, and is used to adjust the conveying attitude of the cotton bales;

[0015] A visual positioning device is installed on top of the posture adjustment mechanism to capture images of the cotton bales and identify the spatial coordinates of all packing straps.

[0016] An ultrasonic cutting mechanism is installed on the frame and located below the conveying mechanism. It is used to move to the corresponding packing strap according to the position coordinates fed back by the visual positioning device and cut from the bottom of the cotton bale.

[0017] A strapping recycling mechanism, installed on the frame and located above the ultrasonic cutting mechanism, is used to collect the cut strapping.

[0018] The system is electrically connected to the conveying mechanism, attitude adjustment mechanism, visual positioning device, ultrasonic cutting mechanism and packing strap recycling mechanism.

[0019] In one alternative embodiment, the conveying mechanism includes a roller with side frames on both sides and a motor mounting bracket at the bottom of the side frames. The conveying mechanism is mounted on the frame via the motor mounting bracket, and a first motor is disposed between the roller and the motor mounting bracket. The first motor drives a sprocket to rotate and drives the roller to rotate, thereby realizing the conveying of cotton bales.

[0020] In one alternative embodiment, the attitude adjustment mechanism is mounted on the frame via a frame, and two first cylinders are arranged on both sides of the frame. The two first cylinders are symmetrically arranged along the center line of the conveying mechanism, and each has a push plate at its output end.

[0021] The two first cylinders simultaneously drive the two push plates to move linearly in the horizontal direction, and the direction of movement is perpendicular to the cotton bale conveying direction.

[0022] In one alternative embodiment, the attitude adjustment mechanism further includes a guide rod that assists the first cylinder in driving the push plate to perform linear motion.

[0023] In one alternative embodiment, the visual positioning device is mounted on top of the frame via a fixed beam. The visual positioning device also includes a camera mounting bracket and a camera. The camera mounting bracket is located at the bottom center of the fixed beam, and the camera is mounted at the bottom of the camera mounting bracket.

[0024] In one alternative embodiment, the ultrasonic cutting mechanism is mounted on the frame via a fixing bracket. The top of the fixing bracket is provided with a linear guide rail and a second cylinder. A sliding seat is provided on the linear guide rail. The output end of the second cylinder is connected to the sliding seat. The second cylinder is guided by the linear guide rail and drives the sliding seat to move linearly in a direction parallel to the cotton bale conveying direction.

[0025] A third cylinder is provided at one end of the sliding seat. The output end of the third cylinder is connected to the linear module. The ultrasonic cutter is fixed on the linear module. The third cylinder drives the linear module and the ultrasonic cutter to rotate.

[0026] A second motor is provided at the bottom of the linear module, and the second motor drives the ultrasonic cutter to move linearly in the vertical direction on the linear module.

[0027] In one alternative embodiment, the ultrasonic cutter includes a cutter holder, an ultrasonic generator, an amplitude transformer, a transducer, and a cutting head. The ultrasonic cutter is connected to the linear module via the cutter holder. The ultrasonic generator, amplitude transformer, transducer, and cutting head are sequentially connected from bottom to top at the end of the cutter holder away from the linear module. The output end of the ultrasonic generator is connected to the transducer via the amplitude transformer, and the output end of the transducer is connected to the cutting head.

[0028] In one alternative embodiment, the strapping recycling mechanism is mounted on the frame via a fixed base. A fourth cylinder is provided at one end of the fixed base away from the frame. The output end of the fourth cylinder is connected to a fixed plate. Both ends of the fixed plate along its length are provided with a baffle rod and a clamping device. The baffle rod is connected to the fixed plate via a first spring.

[0029] The gripping device includes a second spring, a fifth cylinder, and a pneumatic finger. The fifth cylinder is connected to the fixed plate via the second spring, and the output end of the fifth cylinder is connected to the pneumatic finger.

[0030] The fourth cylinder drives the fixed plate to move vertically, causing the baffle rod to contact the top surface of the cotton bale. With the cooperation of the first spring, the baffle rod stops and gathers the cut packing tape. The fifth cylinder drives the pneumatic fingers to clamp the gathered packing tape and transport it to the recycling device.

[0031] In one alternative embodiment, the recycling device is a strapping recycling basket, which is disposed below the strapping recycling mechanism and the conveying mechanism.

[0032] In one alternative embodiment, both the stop bar and the pneumatic finger are equipped with rollers at their working ends. When the pneumatic finger is in a clamping state, the rollers of the stop bar and the pneumatic finger are at the same height and are both in contact with the top surface of the cotton bale.

[0033] The beneficial effects of this invention are as follows:

[0034] (1) This solution uses an ultrasonic cutting mechanism to convert high-frequency electrical energy into high-intensity mechanical vibration. Through the combined effect of "vibration friction heat generation" and "high-frequency tearing", the material is softened and separated instantly. The cut is smooth and burr-free, and no debris or dust is generated. This avoids the contamination of these pollutants to subsequent processes and affects the production of high-purity refined cotton.

[0035] (2) The ultrasonic cutting mechanism of this solution is set below the conveying mechanism. The cutting head extends from the gap between the rollers and cuts the packing strap from the bottom of the cotton bag. After the cutting is completed, the packing strap will loosen and bulge, but it will still be pressed down by the weight of the cotton bag and will not break to the sides, thus eliminating the safety threat to equipment and personnel.

[0036] (3) This solution actively intercepts loose and raised packing straps by setting up a baffle bar, and actively clamps them into the packing strap recycling box by pneumatic fingers, increasing the success rate of the recycling action from 70% to 100% from the original device, avoiding the subsequent manual sorting process and improving production efficiency.

[0068] This application provides a device for cutting the packing straps of refined cotton bales, such as... Figures 1 to 3 As shown, the device includes a frame 6 and a conveying mechanism 1, a posture adjustment mechanism 2, a vision positioning device 3, an ultrasonic cutting mechanism 4, and a strapping tape recycling mechanism 5, all connected to the frame 6 via their respective connection structures. It also includes a control system electrically connected to the aforementioned devices, specifically a PLC controller. The strapping tape recycling frame 7 is located on one side of the frame 6 and below the conveying mechanism 1. It should be noted that this is for better demonstration of the structure of this application. Figures 1 to 3 The conveyor mechanism 1 shown in the figure only shows part of the conveyor track. The end of the conveyor mechanism 1 away from the packing strap recycling box 7 is also equipped with a conveyor track, which is used to transport the cotton bales 8 into the device for cutting and recycling the packing strap 9. The conveyor track of the conveyor mechanism 1 is also set above the packing strap recycling box 7, which is used to transport the cotton bales 8 that have been cut with the packing strap 9 to the next process.

[0069] Preferably, the conveying mechanism 1 is installed on the frame 6 to convey the cotton bale 8 into the device for cutting and recycling the packing strap 9, and then output the cotton bale 8 to the device for the next process.

[0070] Specifically, such as Figures 4 to 6As shown, the conveying mechanism 1 includes a roller 101, with side frames 102 on both sides of the roller 101 and a motor mounting bracket 103 at the bottom of the side frames 102. The conveying mechanism 1 is mounted on the frame 6 via the motor mounting bracket 103. A first motor 104 is positioned between the roller 101 and the motor mounting bracket 103. The first motor 104 drives the sprocket 105 to rotate and drives the roller 101 to rotate, thereby conveying the cotton bales 8. Considering that the weight of the cotton bales 8 is 50-65kg, the conveying mechanism 1 adopts a sprocket-driven roller conveyor line, which has a strong load-bearing capacity and ensures the smooth conveying of the cotton bales 8. The roller 101 is made of rubber-coated rollers to avoid slippage of the cotton bales during conveying and to effectively prevent the generation of static electricity.

[0071] More specifically, the gap between each roller 101 is 25cm, which is greater than the width of the strapping 9. The working end of the strapping recovery mechanism 5 is directly below the gap between the two rollers 101, and a strapping recovery basket 7 is provided below the rollers 101. After the strapping recovery mechanism 5 has completely blocked, gathered, and clamped all the strapping 9 on the cotton bale 8, the cotton bale 8 continues to be conveyed forward until it leaves the area below the strapping recovery mechanism 5. Then, the strapping recovery mechanism 5 releases, allowing all the strapping 9 to fall from the gap between the two rollers 101 into the strapping recovery basket 7, thus completing the recovery of the strapping 9.

[0072] Preferably, the attitude adjustment mechanism 2 is installed on the frame 6 and located on both sides of the conveying mechanism 1, and is used to adjust the conveying attitude of the cotton bale 8 so that the center line of the cotton bale 8 is aligned with the center line of the conveying mechanism 1.

[0073] Specifically, such as Figures 7 to 9 As shown, the attitude adjustment mechanism 2 is mounted on the frame 6 via the frame 201. Two first cylinders 202 are arranged on both sides of the frame 201. The two first cylinders 202 are symmetrically arranged along the center line of the conveying mechanism 1, and each has a push plate 203 at its output end. The two first cylinders 202 simultaneously drive the two push plates 203 to move linearly in the horizontal direction, and the direction of movement is perpendicular to the conveying direction of the cotton bale 8, pushing the cotton bale 8 to the middle position of the conveying mechanism 1, aligning the center line of the cotton bale 8 with the center line of the conveying mechanism 1, thereby establishing a reference coordinate for the visual positioning device 3, thus ensuring the cutting success rate of the ultrasonic cutting mechanism 4 and the recycling success rate of the packing strap recycling mechanism 5.

[0074] Furthermore, the attitude adjustment mechanism 2 also includes a guide rod 204, which assists the first cylinder 202 in driving the push plate 203 to perform linear motion.

[0075] Preferably, the visual positioning device 3 is installed on top of the posture adjustment mechanism 2 to capture images of the cotton bale 8 and identify the spatial coordinates of all the packing straps 9. The control system receives the recorded information from the visual positioning device 3 and controls the start and stop of the conveying mechanism 1, the posture adjustment mechanism 2, the ultrasonic cutting mechanism 4 and the packing strap recycling mechanism 5 accordingly to achieve precise cutting of the packing straps 9.

[0076] Specifically, such as Figure 10 and Figure 11 As shown, the visual positioning device 3 is installed on the top of the frame 201 via the fixed beam 301. The visual positioning device 3 also includes a camera mounting bracket 302 and a camera 303. The camera mounting bracket 302 is located at the bottom center of the fixed beam 301, and the camera 303 is installed at the bottom of the camera mounting bracket 302. The shooting end of the camera 303 faces the top surface of the cotton bale 8, so as to record the position coordinates of the packing strap 9 required for cutting and recycling in a timely manner and feed them back to the control system.

[0077] Preferably, the ultrasonic cutting mechanism 4 is installed on the frame 6 and located below the conveying mechanism 1. It is used to move to the corresponding packing strap 9 according to the position coordinates fed back by the visual positioning device 3 and cut from the bottom of the cotton bag 8. After the cutting is completed, the packing strap 9 will loosen and bulge, but it will still be pressed down by the weight of the cotton bag 8 and will not bounce to the sides, thus eliminating the safety threat to equipment and personnel.

[0078] Specifically, such as Figures 12 to 14 As shown, the ultrasonic cutting mechanism 4 is mounted on the frame 6 via a fixing bracket 401. A linear guide rail 402 and a second cylinder 403 are provided on the top of the fixing bracket 401. A sliding seat 404 is provided on the linear guide rail 402. The output end of the second cylinder 403 is connected to the sliding seat 404. The second cylinder 403 is guided by the linear guide rail 402 and drives the sliding seat 404 to move linearly in a direction parallel to the conveying direction of the cotton bale 8. A third cylinder 405 is provided at one end of the sliding seat 404. The output end of the third cylinder 405 is connected to the linear module 406. The ultrasonic cutter 407 is fixed on the linear module 406. The third cylinder 405 drives the linear module 406 and the ultrasonic cutter 407 to rotate. When the ultrasonic cutter 407 is in a vertical working state, the third cylinder 405 can drive the ultrasonic cutter 407 to rotate 90° clockwise or counterclockwise. The linear motion driven by the second cylinder 403 and the rotary motion driven by the third cylinder 405 are used to store the ultrasonic cutter 407 inside the frame 6 when it is not in operation, preventing external dust from affecting the ultrasonic cutter 407 and improving its service life. Simultaneously, the rotary motion driven by the third cylinder 405 can also fine-tune the cutting angle when the cotton bale 8 and the packing strap 9 shift position, ensuring precise cutting of the packing strap 9.

[0079] A second motor 408 is installed at the bottom of the linear module 406. The second motor 408 drives the ultrasonic cutter 407 to move in a straight line in the vertical direction on the linear module 406. When the vision positioning device 3 identifies that a certain packing strap 9 of the cotton bale 8 is located in the gap position of the roller 101 above the working end of the ultrasonic cutter 407, the control system stops the conveying mechanism 1. The second motor 408 drives the ultrasonic cutter 407 to rise and extend from the gap of the roller 101 to complete the cutting of the target packing strap 9. After the cutting is completed, the second motor 408 drives the ultrasonic cutter 407 to descend slightly. When the next packing strap 9 arrives, it rises again to cut. This process is repeated until all the packing straps 9 are cut.

[0080] Further details can be found in the following references. Figure 14 The ultrasonic cutter 407 includes a cutter holder 4071, an ultrasonic generator 4072, an amplitude transformer 4073, a transducer 4074, and a cutting head 4075. The ultrasonic cutter 407 is connected to the linear module 406 through the cutter holder 4071. The ultrasonic generator 4072, the amplitude transformer 4073, the transducer 4074, and the cutting head 4075 are connected sequentially from bottom to top at the end of the cutter holder 4071 away from the linear module 406. The output end of the ultrasonic generator 4072 is connected to the transducer 4074 through the amplitude transformer 4073, and the output end of the transducer 4074 is connected to the cutting head 4075. The ultrasonic generator 4072 generates high-frequency electrical energy, which is converted into mechanical vibration by the transducer 4074 and amplified by the amplitude transformer 4073. The amplified high-intensity mechanical vibration is transmitted to the cutting head 4075. When the cutting head 4075 comes into contact with the packing strap 9, friction heat and high-frequency tearing occur, which makes the packing strap 9 neatly separated. The cut is fused and sealed by heat, avoiding the generation of debris and dust, thereby avoiding these contaminants from contaminating subsequent processes and affecting the production of high-purity refined cotton.

[0081] Preferably, the strapping tape recycling mechanism 5 is mounted on the frame 6 and located above the ultrasonic cutting mechanism 4, for collecting the cut strapping tape 9;

[0082] Specifically, such as Figures 15 to 18 As shown, the strapping recycling mechanism 5 is mounted on the frame 201 via a fixed base 501. A fourth cylinder 502 is provided at one end of the fixed base 501 away from the frame 201. The output end of the fourth cylinder 502 is connected to a fixed plate 503. Both ends of the fixed plate 503 along its length are provided with a baffle rod 504 and a clamping device 505. The baffle rod 504 is connected to the fixed plate 503 via a first spring 506.

[0083] For details, please refer to the following: Figure 18The gripping device 505 includes a second spring 5051, a fifth cylinder 5052 and a pneumatic finger 5053. The fifth cylinder 5052 is connected to the fixed plate 503 through the second spring 5051, and the output end of the fifth cylinder 5052 is connected to the pneumatic finger 5053.

[0084] The fourth cylinder 502 drives the fixed plate 503 to move vertically, causing the baffle rod 504 to contact the top surface of the cotton bale 8. With the cooperation of the first spring 506, the baffle rod 504 stops and gathers the cut strapping 9. The fifth cylinder 5052 drives the pneumatic finger 5053 to clamp all the gathered strapping 9 and transport it to the recycling device, i.e., the strapping recycling basket 7. The strapping recycling basket is located below the strapping recycling mechanism 5 and the conveying mechanism 1. Because the ultrasonic cutting mechanism 4 cuts the strapping 9 from the bottom of the cotton bale 8, the strapping 9 will not break apart to the sides due to the weight of the cotton bale 8. However, the sudden release of tension will cause the strapping 9 on the top surface of the cotton bale to bulge, such as... Figure 19 As shown, after the two baffles 504 stop and gather all the cut strapping 9 at the raised parts on both sides of the strapping 9, the two pneumatic fingers 5053 will clamp the raised parts of the strapping 9, clamping all the strapping 9 on a cotton bale 8 into a whole, while the cotton bale 8 continues to move forward until it is completely separated from the strapping recycling mechanism 5. At this time, the pneumatic fingers 5053 are released, and the strapping 9 falls from the gap of the roller 101 into the strapping recycling basket 7 below, completing the recycling of the strapping 9.

[0085] Preferably, refer again Figure 18 and Figure 19 Both the stop bar 504 and the pneumatic finger 5053 are equipped with rollers 507 at their working ends. When the pneumatic finger 5053 is in the clamping state, the rollers 507 of the stop bar 504 and the pneumatic finger 5053 are at the same height and are in contact with the top surface of the cotton bale 8. The purpose of the rollers 507 is to stop, gather, and clamp the packing strap 9 when the stop bar 504 and the pneumatic finger 5053 are in contact with the top of the cotton bale 8, without affecting the continued conveying of the cotton bale 8 to the next process. The rollers 507 change the sliding friction of the contact area between the stop bar 504 and the pneumatic finger 5053 and the top surface of the cotton bale 8 into rolling friction, thereby achieving smooth conveying of the cotton bale 8.
