Description

Technical Field

[0001] This utility model relates to the field of combing machine technology, and in particular to a licker roller structure for a combing machine. Background Technology

[0002] Wool is mainly composed of protein. Humans have used wool since the Neolithic Age. It spread from Central Asia to the Mediterranean and other parts of the world, and thus became the main textile raw material in Asia and Europe. Wool fibers are soft and elastic and can be used to make textiles such as woolen fabrics, yarns, blankets, and felts. Wool products are characterized by their full feel, good warmth retention, and comfortable wear. Sheep wool accounts for a considerable proportion of textile raw materials. Sheep wool is divided into five categories according to fineness and length: fine wool, semi-fine wool, long wool, crossbred wool, and coarse wool.

[0003] A document with publication number CN214458502U discloses a novel licker-in roller structure for a wool carding machine, including a machine body with a carding box installed inside. The machine body has a feed inlet at the top and a discharge outlet at the bottom. The carding box houses a first licker-in roller, a second licker-in roller, and a third licker-in roller. This invention, by setting up the first, second, and third licker-in rollers, an electric push rod, and a cleaning brush, forms a triangle. The first licker-in roller rotates counterclockwise while the rollers rotate clockwise; the second and third licker-in rollers rotate counterclockwise while the cylinder rotates clockwise. The first licker-in roller initially cards and removes impurities from the wool. The two rollers then guide the wool onto the second and third licker-in rollers, where they perform a second carding and impurity removal, thus accelerating the carding speed and improving overall work efficiency.

[0004] The piercing roller structure uses an electromagnet to fix the piercing needles onto the roller. While this solves the problem of replacing the piercing needles, the electromagnet requires an external power supply, which makes the wiring layout and maintenance difficult and also poses a significant risk of leakage.

[0005] Therefore, it is necessary to provide a licker-in roller structure for a carding machine to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] like Figure 1-5 The diagram shows the licker-in roller structure for a carding machine provided by this utility model, comprising: a licker-in roller body 1 for use in CN214458502U or other carding machines; a plurality of detachable licker needles 2 mounted on the licker-in roller body 1; specifically, an mounting groove 3 is formed on the licker-in roller body 1; an insert block 4 is mounted on the bottom of the licker needle 2; the insert block 4 is inserted into the mounting groove 3; an anti-detachment structure is provided between the insert block 4 and the mounting groove 3; the anti-detachment structure includes two symmetrically arranged anti-detachment heads 5 mounted on the insert block 4; an anti-detachment groove 9 is formed in the mounting groove 3; the top of the anti-detachment head 5 is embedded in the anti-detachment groove 9; and a spring 6 is installed between the mounting groove 3 and the bottom of the insert block 4; by compressing the spring 6, the insert block 4 is pushed away from the mounting groove 3. Applying pressure in the radial direction ensures that the anti-detachment head 5 is tightly embedded in the anti-detachment groove 9. To facilitate the removal of the needle 2, an inlet / outlet groove 7 is provided on the mounting groove 3. When the needle 2 needs to be replaced, press the insert block 4 radially to further compress the spring 6, thus removing the anti-detachment head 5 from the anti-detachment groove 9. Then, rotate the insert block 4 by 90 degrees to rotate the anti-detachment head 5 into the inlet / outlet groove 7. Lift the insert block 4 to remove it from the mounting groove 3. Then, follow the above steps in reverse order to install a new needle 2. This achieves a detachable and easy-to-replace installation method for the needle 2. This installation method uses a purely mechanical structure design, eliminating the need for wiring and making it safer to use.

[0028] By setting an installation groove 3 on the squeegee roller body 1 and installing a detachable insert 4 in the installation groove 3, the damaged squeegee 2 can be easily replaced. By setting an anti-detachment head 5, a spring 6, an inlet / outlet groove 7 and an anti-detachment groove 9, the insert 4 can be easily installed and fixed. The squeegee 2 adopts a purely mechanical installation method, which eliminates the need to lay wiring inside the squeegee roller body 1, making maintenance easier and safer to use.

[0029] Example 2:

[0030] like Figure 4 As shown, a guide groove 10 is provided in the mounting groove 3. The guide groove 10 connects the anti-detachment groove 9 and the inlet / outlet groove 7. In use, the anti-detachment head 5 is inserted into the inlet / outlet groove 7, so that the height of the anti-detachment head 5 is lower than the guide groove 10. Then, the insert block 4 can be rotated to make the anti-detachment head 5 slide along the guide groove 10 until the anti-detachment head 5 slides into the anti-detachment groove 9, thus completing the connection between the anti-detachment head 5 and the anti-detachment groove 9.

[0031] By setting a guide groove 10 in the mounting groove 3, the rotation of the anti-detachment head 5 in the mounting groove 3 can be guided, and the anti-detachment head 5 can be guided into the anti-detachment groove 9.

[0032] Example 3:

[0033] like Figure 4-5 As shown, a guide tube 12 is installed at the bottom center of the plug 4, and the top of the spring 6 is sleeved on the guide tube 12. When the plug 4 compresses the spring 6, the spring 6 will not deviate too far from the bottom center of the plug 4 because it is sleeved on the guide tube 12, so that the plug 4 is subjected to more balanced force (pressure from the spring 6).

[0034] By installing a guide tube 12 at the bottom center of the insert 4, the top of the spring 6 can be positioned, so that the insert 4 is subjected to balanced force.

[0035] Example 4:

[0036] like Figure 4-5 As shown, a guide rod 11 is fixedly installed at the bottom center of the mounting groove 3. The top end of the guide rod 11 is inserted into the guide tube 12. When the insert block 4 is inserted into the mounting groove 3, the guide tube 12 at the bottom of the insert block 4 is sleeved on the guide rod 11. Thus, through the insertion between the guide rod 11 and the guide tube 12, the insert block 4 is supported and limited from the inside, so that the position of the insert block 4 in the mounting groove 3 is more accurate and stable.

[0037] By installing a guide rod 11 at the bottom center of the mounting groove 3, the insert 4 can be supported and limited from the inside, making the insert 4 more stable.

[0038] Example 5:

[0039] like Figure 4-5 As shown, an outer tube 13 is fixedly installed at the bottom of the insert block 4. The outer tube 13 is sleeved on the outside of the spring 6, limiting the position of the end of the spring 6 from the outside, further preventing the spring 6 from being installed eccentrically, so as to avoid the problem of the top of the spring 6 being eccentric due to the failure of the guide tube 12, thereby improving the stability of the spring 6 in use.

[0040] By installing an outer tube 13 at the bottom of the insert 4, the spring 6 can be further limited, thereby improving the stability of the spring 6 in use.

[0041] Example 6:

[0042] A boss is provided on the top of the anti-detachment head 5, which makes the top diameter of the anti-detachment head 5 smaller, making it easier to insert into the anti-detachment groove 9.

[0043] The anti-detachment head 5 has a protrusion on its top, which makes it easy for the anti-detachment head 5 to be inserted into the anti-detachment groove 9.

[0044] Working principle: When the needle 2 needs to be replaced, press the insert block 4 radially to further compress the spring 6, causing the anti-detachment head 5 to come out of the anti-detachment groove 9. Then rotate the insert block 4 by 90 degrees so that the anti-detachment head 5 rotates into the inlet / outlet groove 7. Then lift the insert block 4 to remove it from the installation groove 3. Then, follow the above steps in reverse order to install the new needle 2. This achieves the detachable and easy-to-replace features of the needle 2. This installation method adopts a purely mechanical structure design, which does not require wiring and is safer to use.

[0045] It is worth noting that when installing the plug 4, the plug 4 is inserted into the mounting groove 3, and at the same time, the anti-detachment head 5 is inserted into the inlet / outlet groove 7. Press the plug 4 so that the height of the anti-detachment head 5 is lower than the guide groove 10. Then rotate the plug 4 so that the anti-detachment head 5 slides along the guide groove 10 until the anti-detachment head 5 slides into the anti-detachment groove 9, thus completing the connection between the anti-detachment head 5 and the anti-detachment groove 9.
