Description

Technical Field

[0001] This utility model relates to the field of cotton opening roller technology, specifically a cotton opening roller structure with replaceable toothed racks. Background Technology

[0002] In the production process of cotton products, cotton raw materials often need to be stored. Various factors such as storage before raw material processing can lead to cotton caking, large unevenness in cotton fiber length, and insufficient looseness, which are not suitable for the feeding requirements of cotton carding machines. Therefore, it is necessary to loosen the cotton fibers to increase their looseness and make them meet the feeding requirements of cotton carding machines.

[0003] The existing patent CN219363897U discloses a cotton opening and combing machine, which relates to the field of cotton processing equipment technology. Specifically, it is a cotton opening and combing machine, which includes a box body. The inner wall of the box body is respectively provided with a rotatable round rod and a transmission roller. A round roller is installed on the outer surface of the round rod, and a first opening rod is installed on the outer surface of the round roller. An inclined plate, an arc plate and a support plate are installed on the inner wall of the box body.

[0004] However, the opening rollers and opening rods of opening machines are mostly fixed to the rollers by welding. During use, the spacing between the opening rods cannot be changed according to actual needs, so the opening effect on cotton cannot be selectively determined, resulting in poor flexibility. To address this, we propose a cotton opening roller structure with replaceable racks to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1

[0020] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a cotton opening roller structure with replaceable toothed racks, including a roller body 1. The outer wall of the roller body 1 is recessed with a plurality of insertion grooves 2. The bottom inner wall of the insertion grooves 2 is recessed with a plurality of anti-detachment slots 5. Anti-detachment blocks 9 are slidably engaged in the anti-detachment slots 5. One end face of the anti-detachment block 9 is coaxially fixedly connected to one end of a cylindrical block 8. The cylindrical block 8 is slidably sleeved in the anti-detachment slots 5. The other end of the cylindrical block 8 is coaxially fixedly connected to an opening rod 4. The opening rod 4 slides through a circular hole 6. The circular hole 6 is respectively provided through the anti-detachment plate 3. The anti-detachment plate 3 is slidably inserted into the insertion groove 2. One end of the anti-detachment plate 3 is fixedly installed on the roller body 1 by fixing bolts 7. The fixing bolts 7 are respectively connected to one end of the roller body 1 by a threaded structure.

[0021] Example 2

[0022] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the insertion groove 2 is evenly distributed around the roller body 1, so that the opening rods 4 installed in the insertion groove 2 are more evenly distributed.

[0023] Specifically, one end of the insertion slot 2 is recessed to provide an anti-disengagement groove 21.

[0024] Furthermore, the anti-detachment plate 3 has an L-shaped structure, and a snap-fit ​​plate 31 is fixedly connected to one end of the anti-detachment plate 3. Both the snap-fit ​​plate 31 and the anti-detachment groove 21 have a straight structure. The snap-fit ​​plate 31 and the anti-detachment groove 21 are inserted and matched to prevent the anti-detachment plate 3 from detaching from the snap-fit ​​groove 2.

[0025] Specifically, the anti-detachment slot 5 includes a track groove 51, an insertion hole 52, and an anti-detachment opening 53. The insertion hole 52 is opened on the bottom inner wall of the insertion slot 2. One end of the insertion hole 52 is connected to the anti-detachment opening 53. The insertion hole 52 and the anti-detachment opening 53 are connected to the track groove 51 on one side. The track groove 51 is recessed in the bottom inner wall of the insertion slot 2.

[0026] During assembly, the cylindrical block 8 and the anti-detachment block 9, which are fixed to the loosening rod 4, pass through the circular hole 6 respectively. Then, the anti-detachment block 9 is inserted into the insertion hole 52 of the anti-detachment slot 5, and the loosening rod 4 is manually pressed to move the anti-detachment block 9 into the runway slot 51. After the loosening rod 4 is inserted, the anti-detachment plate 3 is embedded into the insertion slot 2, and then... Figure 2The left side is shown. Manually push the anti-detachment plate 3 so that the snap-fit ​​plate 31 fixed at the end of the anti-detachment plate 3 is inserted into the anti-detachment groove 21. At the same time, the other end of the L-shaped anti-detachment plate 3 is pressed against the outer wall of the roller body 1. When the anti-detachment plate 3 moves, it drives the loosening rod 4 sleeved in the round hole 6 to move synchronously. The loosening rod 4 drives the fixed cylindrical block 8 to slide in the anti-detachment opening 53. At the same time, the anti-detachment block 9 slides in the track groove 51. The cylindrical block 8 stops after moving to the end of the anti-detachment opening 53 away from the insertion hole 52, that is, the anti-detachment plate 3 is inserted into place. Then, use the fixing bolt 7 to pass through the mounting hole provided at the end of the anti-detachment plate 3, and cooperate with the threaded hole opened on the end face of the roller body 1 to fix and limit the position of the anti-detachment plate 3, so that the anti-detachment plate 3 limits and fixes the position of the loosening rod 4, while ensuring the smoothness of the outer wall of the roller body 1.

[0027] Furthermore, the anti-detachment slots 5 are evenly distributed along the length of the insertion slot 2, the anti-detachment opening 53 is a U-shaped structure, the track groove 51 is a track-shaped structure, and the insertion hole 52 is a round hole structure. The opening width of the anti-detachment opening 53 is equal to the outer diameter of the cylindrical block 8, the outer diameter of the anti-detachment block 9 is equal to the opening width of the track groove 51, the outer diameter of the cylindrical block 8 is smaller than the outer diameter of the anti-detachment block 9, and the opening width of the track groove 51 is equal to the inner diameter of the insertion hole 52. After the anti-detachment block 9 is inserted into the track groove 51, the anti-detachment block 9 can move within the track groove 51. At the same time, since the outer diameter of the anti-detachment block 9 is larger than the outer diameter of the cylindrical block 8 and the outer diameter of the anti-detachment block 9 is larger than the opening width of the anti-detachment opening 53, the anti-detachment block 9 can be completely locked into the track groove 51, preventing the anti-detachment block 9 from detaching from the track groove 51, thus limiting and fixing the position of the release rod 4.

[0028] According to the actual spacing required during loosening, the spacing between each loosening rod 4 is adjusted in a timely manner. During assembly, the cylindrical block 8 and the anti-detachment block 9 fixed to the loosening rod 4 pass through the circular hole 6 respectively. Then, the anti-detachment block 9 is inserted into the insertion hole 52 of the anti-detachment slot 5, and the loosening rod 4 is manually pressed to move the anti-detachment block 9 into the track groove 51. After the loosening rod 4 is inserted, the anti-detachment plate 3 is embedded into the insertion slot 2, and then... Figure 2The left side is shown. Manually push the anti-detachment plate 3 so that the snap-fit ​​plate 31 fixed to the end of the anti-detachment plate 3 is inserted into the anti-detachment groove 21. At the same time, the other end of the L-shaped anti-detachment plate 3 is pressed against the outer wall of the roller body 1. When the anti-detachment plate 3 moves, it drives the loosening rod 4 sleeved in the round hole 6 to move synchronously. The loosening rod 4 drives the fixed cylindrical block 8 to slide in the anti-detachment opening 53. At the same time, the anti-detachment block 9 slides in the track groove 51. The cylindrical block 8 stops after moving to the end of the anti-detachment opening 53 away from the insertion hole 52, that is, the anti-detachment plate 3 is inserted in place. Then, use the fixing bolt 7 to pass through the mounting hole provided at the end of the anti-detachment plate 3, and cooperate with the threaded hole opened on the end face of the roller body 1 to fix and limit the position of the anti-detachment plate 3, so that the position of the loosening rod 4 is limited by the anti-detachment plate 3, and at the same time, the smoothness of the outer wall of the roller body 1 is ensured. When it is necessary to disassemble and replace the loosening rod 4, first use a tool (such as a wrench) to remove the fixing bolt 7 manually, and then manually move towards Figure 2 The right-side anti-detachment plate 3 is shown. The anti-detachment plate 3 drives the loosening rod 4 to move to the right in sync. The loosening rod 4 drives the cylindrical block 8 to the position of the insertion hole 52. Then, the loosening rod 4 is manually pulled out away from the roller body 1. The cylindrical block 8 and the anti-detachment block 9 pass through the round hole 6 respectively, so that the loosening rod 4 can be disassembled.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
