Abstract
Description
Technical Field
[0001] The utility model belongs to the field of knitting equipment, and in particular relates to a tooth opening structure of a computerized flat knitting machine. Background Art
[0002] With the continuous improvement of the intelligence of computer flat knitting machines, the scope of use of flat knitting machines is becoming more and more extensive, and the requirements for the needle bed of the flat knitting machine are constantly increasing. It is necessary to make the knitting needles move faster, position more accurately, and ensure good sliding. The existing computer flat knitting machines generally use a needle plate that is first milled with parallel and equidistant slots. The slots include a tooth groove near the top of the needle plate and a slot located in the middle of the needle plate. The tooth groove is embedded with a combination of an insert and a tooth plate or a combination of an insert and a sinker. The slot is embedded with an insert. The gap between two adjacent inserts and the gap between the insert and the tooth plate (or sinker) form a needle groove, and the knitting needle is installed in the needle groove. Generally, the movement of the knitting needle is controlled by the mountain board frame, the movement direction of the knitting needle is controlled by two adjacent inserts, and the gap between the inserts controls the shaking of the knitting needle. As long as the knitting needle is properly controlled, the use function of the flat knitting machine can be realized. Increasing the movement speed of the knitting needle can improve the use efficiency of the flat knitting machine.
[0003] At present, in order to control the shaking of knitting needles, the gap between the knitting needles and the two adjacent inserts is generally reduced, so that the inserts can completely guide the movement of the knitting needles, so that the shaking of the knitting needles in the needle grooves can be controlled. However, if the gap is too small, it is not conducive to the penetration of lubricating oil, wear and noise cannot be avoided, energy consumption increases, and the running speed cannot be increased. Moreover, the flat knitting machine cannot be continuously refueled when working. Once too much oil is brought to the needle hook by the moving knitting needle, it will contaminate the knitted fabric and produce oil needle defects, which will seriously cause the knitted fabric to be scrapped in batches. On the contrary, increasing the gap can increase the movement speed of the knitting needle, but if the knitting needle is not clamped by the two adjacent inserts, it will cause left and right shaking, which will cause problems such as missing needles and holes in the knitted fabric. Utility Model Content
[0004] In view of the above problems, the utility model provides a tooth structure of a computerized flat knitting machine, which can clamp the knitting needles and improve the stability of the knitting needles. The specific technical solutions are as follows:
[0005] A tooth mouth structure of a computerized flat knitting machine comprises a tooth mouth plate or a sinker and an insert arranged in a tooth mouth groove, a needle groove for installing a knitting needle is reserved between the tooth mouth plate or the sinker and the insert, a resistance part is protruded on the insert, one side of the knitting needle contacts the resistance part and the other side contacts the tooth mouth plate or the sinker.
[0006] The abutment portion is protrudingly arranged on the insert, and occupies a part of the space of the needle groove, so that one side of the knitting needle contacts the abutment portion, and the other side contacts the tooth plate or the sinker, thereby clamping the knitting needle and improving the stability of the knitting needle.
[0007] In a specific possible implementation scheme, the interference portion includes a boss protruding from the side wall of the insert, one side of the boss is located in the needle groove, and the other side is located in the tooth groove, the boss is integrally formed with the insert, the boss is arranged along the length direction of the tooth groove, and the boss is provided with at least one side surface coplanar with the side surface of the insert.
[0008] In a specific possible implementation scheme, a snap-in strip extends from the bottom of the insert toward one side of the plug, the snap-in strip is used to fit with the end of the needle plate, a positioning through hole is provided on the insert, and an installation space is provided on the insert for inserting the plug.
[0009] When installing the inlay, insert the inlay into the tooth groove, fit the clamping strip with the end of the needle plate, and then fix the inlay using the positioning through hole. When installing the plug-in, insert the plug-in into the slot and the installation space at the same time, so that the inlay and plug-in can be installed conveniently and quickly.
[0010] Beneficial technical effects of the utility model:
[0011] 1. On the one hand, a normal thickness insert is used to ensure a good gap between the knitting needle and the insert part, which can be well lubricated; on the other hand, a flanged insert and a tooth mouth piece or a sinker are used in the tooth mouth groove to press the knitting needle tightly, which reduces the gap between the knitting needle and the flange, and between the knitting needle and the tooth mouth piece or the sinker, and can play a good role in clamping the knitting needle, thereby stabilizing the knitting needle;
[0012] 2. A smaller gap will produce a role similar to that of an oil scraper ring, preventing oil, dust, etc. from being driven upward through the knitting needles and affecting the quality of the woven fabric. BRIEF DESCRIPTION OF THE DRAWINGS
