[0001] This utility model relates to the technical field of toothed plates, specifically a toothed plate. Background Technology

[0002] A typical toothed looper has a stepped mounting section at the rear and an upward-extending release section at the front. The mounting section has a positioning hole for the steel wire rotation shaft to pass through, and the release section has a small hole for the toothed steel wire to pass through. One side of the body has three stamped lateral protrusions for contacting the groove wall of the needle bed. A space is created between the toothed looper and the needle bed groove wall to hold a sinker. After the yarn is looped, the formed loop needs to pass over the toothed steel wire, using it as a support point, and fall through the gap between two toothed steel wires fixed to the toothed looper.

[0003] The Chinese patent announcement CN214992201U discloses an adjustable toothed plate, the key technical features of which are: it includes an installation part and a release part; the installation part is provided with a positioning hole; an elastic pressure foot is integrally connected below the release part; the release part includes an inclined side away from the installation part; the release part is provided with a plurality of through holes penetrating itself for toothed steel wires to pass through; the through holes are evenly spaced along the inclined side.

[0004] In the above scheme, the insert is fixed by the first and second annular limiting strips, which results in the following disadvantages: the insert is not stable enough during use and the fixing method is limited. Utility Model Content

[0005] The purpose of this invention is to provide a toothed plate to solve the problems of insufficient stability and limited fixing methods of the insert during use.

Anti-slip texture. Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a toothed jaw plate includes an elastic pressure foot 1, which is integrally connected to the toothed jaw plate body 2. A positioning hole 3 is provided on the front side of the toothed jaw plate body 2. A mounting groove 4 is provided on the top surface of the toothed jaw plate body 2. Several inserts 5 are detachably mounted inside the mounting groove 4. Several locking grooves 6 are provided on the top surface of the mounting groove 4. A first annular limiting strip 7 is fixed inside each of the locking grooves 6. Locking pieces 8 are fixed to the bottom surfaces of the inserts 5. The locking pieces 8 are detachable. The locking plates are installed in several locking grooves 6. The outer walls of several locking plates 8 are fixed with second annular limiting strips 9. The second annular limiting strips 9 are snapped into the inner side of the first annular limiting strips 7. The top surface of the toothed plate body 2 is provided with several snap-fit ​​holes 10. The bottom surface of several locking plates 8 is fixed with two elastic snap-fit ​​blocks 11. The elastic snap-fit ​​blocks 11 are detachably snapped into the snap-fit ​​holes 10. The left and right sides of several inserts 5 are provided with semi-circular holes 12. Two adjacent semi-circular holes 12 form a circular through hole.

[0023] In use, the semicircular holes 12 on several inserts 5 cooperate with each other to form circular through holes. These circular through holes provide a passage for the toothed steel wire to pass through. In yarn processing scenarios, yarns of different thicknesses have different requirements for processing parameters. In particular, the sinker angle of the yarn needs to be controlled by adjusting the gap between the toothed steel wires. In the traditional way, when the gap needs to be adjusted, the entire toothed steel wire must be pulled out and re-threaded into the circular through holes at different positions. However, the design of this toothed plate avoids this problem. The operator only needs to slide the insert 5 out of the mounting groove 4, move the toothed steel wire into the next circular through hole, and then insert the insert 5 back into the mounting groove 4 to complete the adjustment. The operation process is simple and quick, saving time.

[0024] In terms of locking and fixing the insert 5, multiple protection mechanisms are adopted. When the locking plate 8 is inserted into the locking groove 6, the second annular limiting strip 9 will encounter a certain resistance at the first annular limiting strip 7. After the operator applies appropriate force, the second annular limiting strip 9 squeezes past the first annular limiting strip 7. At this time, the first annular limiting strip 7 effectively limits the second annular limiting strip 9, thereby achieving the initial fixing of the locking plate 8 and the insert 5, preventing them from falling out due to vibration and other factors during equipment operation, and ensuring the stability of the processing process. At the same time, the elastic snap-fit ​​block 11 is detachably snapped into the snap-fit ​​hole 10. This design provides a second fixation for the insert 5, further enhancing the stability of the insert 5 and effectively avoiding processing quality problems caused by the loosening of the insert 5.

[0025] Through the coordinated action of the elastic pressure foot 1, positioning hole 3, mounting groove 4, insert 5, locking groove 6, first annular limiting strip 7, locking piece 8, second annular limiting strip 9, snap-fit ​​hole 10 and elastic snap-fit ​​block 11, multiple limiting and fixing of insert 5 is achieved, ensuring the stability of insert 5 in all aspects during operation and providing a solid foundation for high-quality yarn processing.

[0026] like Figures 1-4 As shown, several positioning shafts 13 are fixed on the bottom surface of several inserts 5 respectively, and several positioning grooves 14 are opened on the inner bottom surface of the mounting groove 4, and the several positioning grooves 14 respectively position the several positioning shafts 13.

[0027] In use, when the staff installs the insert 5 into the mounting slot 4, the positioning shaft 13 is inserted into the positioning slot 14, which can play an auxiliary positioning role and improve the accuracy of installation.

[0028] like Figures 2-4 As shown, a first magnet 15 is fixed to the bottom surface of several positioning grooves 14, and a second magnet 16 is fixed to the bottom end of several positioning shafts 13. The several second magnets 16 are magnetically attracted to the several first magnets 15 respectively.

[0029] In use, when the operator inserts the positioning shaft 13 into the positioning groove 14, the positioning shaft 13 can be fixed by the magnetic attraction between the first magnet 15 and the second magnet 16, thereby further strengthening the fixing effect on the insert 5.

[0030] like Figures 1-4 As shown, anti-slip textures 17 are provided on the front and rear sides of several inserts 5, and the overall length of the toothed plate body 2 is 27mm and the thickness is 0.41mm.

[0031] During use, the anti-slip texture 17 increases the friction between the operator's fingers and the surface of the insert 5, which helps the operator to better grip the insert 5, thus facilitating the disassembly or installation of the insert 5. The overall length design of 27mm allows the toothed plate body 2 to occupy space reasonably on the equipment, without interfering with other components due to excessive length and affecting the normal operation of the equipment. The 0.41mm thickness design ensures sufficient strength and rigidity of the toothed plate body 2 while minimizing its weight and load on the equipment.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
