Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton cleaning technology, and in particular to a cotton cleaning and impurity removal knife. Background Technology
[0002] In the process of cotton processing, cotton cleaning is a crucial step. Cotton often contains various impurities, such as cottonseed hulls, cotton stalks, and short fibers. The presence of these impurities not only affects the quality of the cotton but also increases the difficulty and cost of subsequent processing. In traditional cotton cleaning equipment, the impurity removal blade is a key component. However, existing impurity removal blades have some problems in use, especially in terms of disassembly and installation as well as fine-tuning the blade body.
[0003] Existing waste removal blades are often fixedly connected to the body of the cotton cleaning machine. The disassembly and installation process is cumbersome and time-consuming. This not only increases maintenance costs but also affects the overall operating efficiency of the equipment. When the waste removal blades are worn or damaged, the machine needs to be stopped for replacement. The complexity of the disassembly and installation process often leads to excessive downtime, which affects the production schedule.
[0004] Secondly, existing waste removal blades often lack flexibility in adjusting their position. Since the blade body and blade holder are basically fixedly connected, it is difficult to fine-tune the position of the blade body once it is installed. This means that in actual use, when encountering different types or thicknesses of cotton, the waste removal blade may not achieve the expected cleaning effect. To solve this problem, it is often necessary to stop the machine and manually adjust the waste removal blade, which not only increases the difficulty of operation but also reduces the automation level of the equipment.
[0005] Therefore, it is necessary to provide a new cotton cleaning and impurity removal knife to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0034] Please see Figures 1 to 5 A cotton cleaning and impurity removal knife, comprising: a cotton cleaning machine body 1, with a licker roller 2 installed inside the cotton cleaning machine body 1, and a knife holder 3 penetrating one side of the licker roller 2; a knife body 4, with the knife holder 3 installed inside the knife body 3; a limiting rod 5, with the limiting rod 5 installed on the top of the knife holder 3 to limit the vertical movement of the knife body 4; a fixing mechanism, with the fixing mechanism installed between the knife holder 3 and the cotton cleaning machine body 1 to fix the knife holder 3 inside the cotton cleaning machine body 1; a rotating rod 6, with the rotating rod 6 installed inside the knife holder 3, and eccentric blocks 7 symmetrically installed in the middle of the rotating rod 6; and a tension spring 8, with the knife body 4 away from the blade. A tension spring 8 is installed equidistantly on one side of the blade holder 3; a limiting mechanism is installed between the rotating rod 6 and the blade holder 3 to limit the rotation of the rotating rod 6 after rotation; the fixing mechanism includes: a round rod 9 and a pin 10; a round rod 9 is symmetrically fixedly connected to one end of the blade holder 3; a round hole corresponding to the two round rods 9 is opened on the inner wall of the cotton cleaning machine body 1 near the round rod 9; an insertion hole is equidistantly opened on the top of the blade holder 3 near the other end; a pin 10 penetrating the top of the cotton cleaning machine body 1 is slidably connected in the two insertion holes; a dust cover 16 is rotatably connected to the top of the blade holder 3; a handle 17 is fixedly connected to one end of the blade holder 3 near the fixed seat 14.
[0035] It should be noted that: Align one end of the blade holder 3 with the round hole on the inner wall of the cotton cleaning machine body 1, allowing the round rod 9 to be smoothly inserted into the corresponding round hole. Then, vertically insert the pin 10 from the top of the cotton cleaning machine body 1, passing through the insertion hole at the other end of the blade holder 3, thus achieving a fixed connection between the blade holder 3 and the cotton cleaning machine body 1. The design of the pin 10 allows it to slide within the insertion hole, ensuring that the blade holder 3 is firmly fixed inside the cotton cleaning machine body 1, while also facilitating subsequent disassembly. When it is necessary to disassemble the blade holder 3, simply pull the pin 10 out of the insertion hole to easily disconnect the blade holder 3 from the cotton cleaning machine body 1. Then, remove the blade holder 3 from the cotton cleaning machine body 1. The disassembly process is completed by removing the cotton cleaning machine body 1. This design not only simplifies the disassembly and installation steps and reduces maintenance costs, but also improves the overall operating efficiency of the equipment. The design of the handle 17 increases the force-bearing area when the operator disassembles and installs the blade holder 3, making disassembly and installation more convenient. The design of the dust cover 16 can effectively prevent dust and debris from entering the interior of the blade holder 3, ensuring its cleanliness and avoiding internal malfunctions caused by debris accumulation. The tension spring 8 fixedly installed on the side of the blade 4 away from the blade edge and inside the blade holder 3 makes the movement distance of the blade 4 more precise during fine adjustment, and also prevents displacement caused by shaking during operation.
[0036] Please see Figures 3 to 5 The limiting mechanism includes: a torsion spring 101, a ratchet 11, and a pawl 12. The ratchet 11 is symmetrically fixedly connected to the middle of the rotating rod 6. Pawls 12 are rotatably connected to the inside of the tool holder 3 at positions corresponding to the two ratchet 11. A torsion spring 101 is installed at the connection between the two pawls 12 and the tool holder 3. The two ratchet 11 and the two pawls 12 are installed together. The inside of the tool holder 3 is provided with clearance grooves 13 at positions corresponding to the two ratchet 11 and the two eccentric blocks 7. A fixed seat 14 is fixedly connected to the end of the tool holder 3 near the pin 10. The rotating rod 6 is rotatably connected to the inner wall of the fixed seat 14. Damping is provided at the connection between the fixed seat 14 and the rotating rod 6. The limiting rod 5 and the tool holder 3 are fixedly connected by bolts. A crank handle 15 is fixedly connected to the end of the rotating rod 6 near the fixed seat 14.
[0037] It should be noted that when fine-tuning of the blade body 4 is required, eccentric blocks 7 are symmetrically installed in the middle of the rotating rod 6. When the rotating rod 6 rotates, the eccentric blocks 7 will drive the blade body 4 to make a slight horizontal movement inside the blade holder 3. This design allows the operator to change the position of the blade body 4 by adjusting the angle of the rotating rod 6 according to actual needs, in order to adapt to different types or thicknesses of cotton. A damping is provided between the fixed seat 14 and the rotating rod 6. The damping force is set to be greater than the tension of the tension spring 8, ensuring that the stability and accuracy of the blade body 4 can be maintained even under long-term operation or slight vibration. The limiting mechanism consists of a torsion spring 101, a ratchet 11, and a pawl 12, which work together between the rotating rod 6 and the blade holder 3. When the rotating rod 6 rotates to the desired position, the pawl 12 engages with the ratchet 11 under the action of the torsion spring 101 to prevent the rotating rod 6 from accidentally rotating back, thereby ensuring the stability and accuracy of the position of the blade body 4. The operator can drive the rotating rod 6 to rotate by shaking the crank handle 15, thereby achieving fine-tuning of the blade body 4. During the fine-tuning process, the operator can observe the position change of the blade 4 in real time and make necessary adjustments according to the actual situation. Once the position of the blade 4 is adjusted to the optimal state, the cooperation of the pawl 12 and the ratchet 11 will lock the rotating rod 6 in the required position, ensuring that the blade 4 remains stable during the cleaning process. The design of the limit rod 5 not only facilitates disassembly and assembly, but also provides connection stability.
[0038] The working principle of the cotton cleaning and impurity removal knife provided by this utility model is as follows:
[0039] I. Easy disassembly and installation of the tool holder
[0040] Installation process:
[0041] First, align one end of the blade holder 3 with the round hole on the inner wall of the cotton cleaning machine body 1, so that the round rod 9 can be smoothly inserted into the corresponding round hole. Next, insert the pin 10 vertically from the top of the cotton cleaning machine body 1, through the insertion hole at the other end of the blade holder 3, to achieve a fixed connection between the blade holder 3 and the cotton cleaning machine body 1. The design of the pin 10 allows it to slide in the insertion hole, thereby ensuring that the blade holder 3 can be firmly fixed inside the cotton cleaning machine body 1, while facilitating subsequent disassembly operations.
[0042] Disassembly process:
[0043] When it is necessary to disassemble the blade holder 3, simply pull the pin 10 out of the socket to easily disconnect the blade holder 3 from the cotton cleaning machine body 1. Then, remove the blade holder 3 from the cotton cleaning machine body 1 to complete the disassembly process. This design not only simplifies the disassembly and installation steps and reduces maintenance costs, but also improves the overall operating efficiency of the equipment.
[0044] II. Fine-tuning of the blade inside the tool holder
[0045] Fine-tuning mechanism:
[0046] An eccentric block 7 is symmetrically installed in the middle of the rotating rod 6. When the rotating rod 6 rotates, the eccentric block 7 will drive the blade body 4 to make a slight horizontal movement inside the blade holder 3. This design allows the operator to change the position of the blade body 4 by adjusting the angle of the rotating rod 6 according to actual needs, so as to adapt to different types or thicknesses of cotton. The fixed seat 14 and the rotating rod 6 are provided with damping. The damping force is set to be greater than the tension of the tension spring 8 to ensure that the stability and accuracy of the blade body 4 can be maintained even under long-term operation or slight vibration.
[0047] Limiting mechanism:
[0048] The limiting mechanism consists of a torsion spring 101, a ratchet 11, and a pawl 12, which work together between the rotating rod 6 and the tool holder 3. When the rotating rod 6 rotates to the desired position, the pawl 12 engages with the ratchet 11 under the action of the torsion spring 101 to prevent the rotating rod 6 from rotating unexpectedly, thereby ensuring the stability and accuracy of the position of the tool body 4.
[0049] Fine-tuning operations:
[0050] The operator can drive the rotating rod 6 to rotate by shaking the handle 15, thereby achieving fine adjustment of the cutter body 4.
[0051] During the fine-tuning process, the operator can observe the position change of the blade 4 in real time and make necessary adjustments according to the actual situation. Once the position of the blade 4 is adjusted to the optimal state, the cooperation of the pawl 12 and the ratchet 11 will lock the rotating rod 6 in the required position, ensuring that the blade 4 remains stable during the cleaning process.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
