Description

Technical Field

[0001] The utility model belongs to the technical field of knitting equipment, and in particular relates to a needle cylinder reinforcement structure of a circular knitting machine. Background Art

[0002] Circular knitting machines, also known as circular weft knitting machines, have developed rapidly due to their multiple loop forming systems, high speed, high output, fast pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] In existing large circular knitting machines, yarn weaving is usually completed by the cooperation of knitting needles and sinkers (or sinkers). The needle cylinder of the large circular knitting machine has a needle groove for accommodating the knitting needles, and the outer side of the needle cylinder has a sinker ring. The sinker ring has a sinker groove for accommodating the sinker. The sinker slides in the sinker groove to operate the yarn to complete the weaving.

[0004] During this process, friction will occur between the bottom of the sinker and the top of the needle cylinder. After a long working time, the top of the needle cylinder is prone to wear. The faster the machine runs, the greater the friction between the sinker and the top of the needle cylinder, causing greater wear on the top of the needle cylinder, resulting in a short service life of the needle cylinder. After a long working time, the serious wear on the top of the needle cylinder can easily cause errors in the matching accuracy, resulting in uneven weaving, wrinkles, straight stripes, and unevenness on the fabric surface. In addition, traditional large circular knitting machines are not equipped with lighting devices. When the top of the needle cylinder is worn, resulting in wrinkles, straight stripes, and unevenness on the woven fabric surface, even if the operator stops the machine to observe, it is difficult to find it. Separate lighting equipment needs to be prepared for inspection, which is time-consuming and labor-intensive.

[0005] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the Invention

[0006] The utility model aims to provide a needle cylinder reinforcement structure for a circular knitting machine, which can increase the service life of the needle cylinder and facilitate observation of the knitting condition of the yarn.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solution:

[0008] A needle cylinder reinforcement structure for a circular knitting machine comprises a needle cylinder, wherein the needle cylinder is provided with a needle groove for accommodating knitting needles, a sinker ring is fixedly provided on the outside of the needle cylinder, a sinker groove for accommodating a sinker piece is provided in the sinker ring, a nozzle groove cooperating with the sinker piece is provided on the top of the needle cylinder, a sink groove is provided on the top of the needle cylinder near the nozzle groove, the sink groove is annularly provided on the top of the needle cylinder, a wear-resistant ceramic block is fixedly provided in the sink groove, the top of the wear-resistant ceramic block extends out of the sink groove, the top of the wear-resistant ceramic block is on the same horizontal plane as the bottom of the sinker piece, and a plurality of lighting devices are fixedly provided on the side of the needle cylinder away from the needle groove, the lighting device comprising a lighting lamp and a power supply for powering the lighting lamp.

[0009] Furthermore, a plurality of support inserts for fixing the sinker ring are fixed in a ring at a position corresponding to the sinker ring on the syringe, and a plurality of insert high feet extend from the top of the support insert toward the sinker ring, and the insert high feet are evenly spaced apart. The sinker ring is fixed on one end of the insert high feet away from the syringe.

[0010] Furthermore, there is a gap between the sinker ring and the syringe, and the two insert high feet are arranged in a group at the bottom of the gap, and the insert high feet in each group are evenly spaced. A steel ring is also fixed to the bottom of the sinker ring, and the steel ring is fixed to the bottom of the sinker ring by a fastener.

[0011] Furthermore, the lighting devices are provided in three groups, and the three groups of lighting devices are evenly arranged in a ring shape.

[0012] Furthermore, the lighting device also includes a fixing frame fixed on the syringe, and the lighting lamp and the power supply are both fixed on the fixing frame.

[0013] Furthermore, the lighting lamp is an LED lighting lamp, and the power source is a battery.

[0014] Furthermore, the wear-resistant ceramic block is made of zirconium oxide material.

[0015] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are:

[0016] The needle cylinder reinforcement structure of the circular knitting machine of the present invention is characterized by providing a sink groove on the top of the needle cylinder and arranging a wear-resistant ceramic block in the sink groove, so that when the circular knitting machine is working, the sinker plate passes through the nozzle groove and contacts and rubs with the top of the wear-resistant ceramic block, thereby avoiding direct friction between the sinker plate and the needle cylinder, thereby improving the service life of the needle cylinder. In addition, a lighting device is fixed on the needle cylinder, which can facilitate the operator to better observe whether the fabric surface effect is abnormal, and to deal with it in time to avoid excessive waste and economic losses caused by fabric surface abnormalities.

[0017] Furthermore, by providing a steel ring and distributed insert high feet, the connection between the sinker ring, the insert high feet and the needle cylinder is tighter, which can effectively reduce the vibration of the sinker ring when the machine is running and improve the overall stability of the sinker ring. In addition, the wider intervals between each insert high foot make it easier to remove cotton wool, reduce cotton wool accumulation, reduce the number of times the machine needs to be cleaned, and thus avoid cotton wool affecting the quality of the cloth.

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 3 As shown, a needle cylinder reinforcement structure of a circular knitting machine includes a needle cylinder 1, a needle groove for accommodating knitting needles 10 is provided in the needle cylinder 1, a sinker ring 2 is fixedly provided on the outside of the needle cylinder 1, a sinker ring 2 is provided with a sinker groove 201 for accommodating a sinker piece 20, and a nozzle groove 11 is provided on the top of the needle cylinder 1 to cooperate with the sinker piece 20. The utility model is an improvement on the structure of a traditional circular knitting machine. The above-mentioned needle cylinder 1 and sinker ring 2 are both structures of conventional circular knitting machines in this field, which have been introduced in the prior art and will not be described in detail herein. When the circular knitting machine is working, the sinker piece 20 moves horizontally back and forth in the sinker groove 201 in the radial direction of the needle cylinder 1, and the sinker piece 20 passes through the nozzle groove 11 and cooperates with the knitting needles 10 in the needle cylinder 1 to complete the knitting of the yarn.

[0034] Unlike the prior art, in the present invention, a sink 12 is provided at the top of the syringe 1 near the nozzle groove 11. The sink 12 is annular and is provided at the top of the syringe 1. A wear-resistant ceramic block 13 is fixed in the sink 12. The wear-resistant ceramic block 13 is arranged along the sink 12. In this embodiment, the top of the wear-resistant ceramic block 13 extends out of the sink 12, and the top of the wear-resistant ceramic block 13 is on the same horizontal plane as the bottom of the sinker 20. Preferably, the cross section of the sink 12 of the present invention is rectangular, and accordingly, the cross section of the wear-resistant ceramic block 13 is also rectangular, which can maximize the wear-resistant ceramic block 13. The friction area with the sinker 20, in order to facilitate the installation of the wear-resistant ceramic block 13, glue is set in the sink 12, and the wear-resistant ceramic block 13 is fixed in the sink 12 by glue. In order to ensure the accuracy of the wear-resistant ceramic block 13, the top of the wear-resistant ceramic block 13 is polished so that the top of the wear-resistant ceramic block 13 is slightly higher than the bottom of the nozzle groove 11 and is on the same horizontal plane as the bottom of the sinker 20. When the large circular knitting machine is working, the sinker 20 passes through the nozzle groove 11 and contacts and rubs with the top of the wear-resistant ceramic block 13. It should be noted that the wear-resistant ceramic block 13 of the utility model is preferably an existing conventional one with a relatively high hardness. The needle cylinder 1 is made of a highly wear-resistant ceramic material, such as zirconium oxide material. Zirconium oxide material has high hardness and wear resistance. Compared with the material of the existing needle cylinder 1, zirconium oxide can withstand friction for a long time without being easily worn. At the same time, in order to facilitate the operator to observe the weaving of the yarn, the needle cylinder 1 is further provided with a plurality of lighting devices 3 on the side away from the needle groove. The lighting device 3 includes a lighting lamp 31 and a power supply 32 for supplying power to the lighting lamp 31. The lighting device 3 also includes a fixing frame 33 fixed on the needle cylinder 1. The lighting lamp 31 and the power supply 32 are both fixed on the fixing frame 33. In this embodiment, the fixing frame 33 is connected to the needle cylinder 1. It is fixed on the side wall of the needle cylinder 1 through bolt fasteners 34. Preferably, the lighting device 3 of the utility model is provided with three groups, and the three groups of lighting devices 3 are evenly arranged in a ring. Accordingly, the lighting device 3 is arranged on the side wall of the needle cylinder 1 near the top, which is convenient for observing the yarn on the needle cylinder 1. The lighting lamp 31 is preferably a conventional LED lighting lamp, and the power supply 32 is preferably a conventional battery. With this arrangement, when the large circular knitting machine has been running at high speed for a long time, the operator can turn on the lighting device 3 to better observe whether the fabric surface effect is abnormal when stopping the machine for inspection, and deal with it in time to avoid excessive waste and economic losses due to abnormal fabric surface.

[0035] The needle cylinder reinforcement structure of the circular knitting machine of the present invention is characterized by providing a sink groove 12 on the top of the needle cylinder 1 and arranging a wear-resistant ceramic block 13 in the sink groove 12, so that when the circular knitting machine is working, the sinker 20 passes through the nozzle groove 11 and contacts and rubs with the top of the wear-resistant ceramic block 13, thereby avoiding direct friction between the sinker 20 and the needle cylinder 1, thereby improving the service life of the needle cylinder 1, and a lighting device 3 is fixed on the needle cylinder 1, which can facilitate the operator to better observe whether the fabric surface effect is abnormal, and to deal with it in time to avoid excessive waste and economic losses caused by fabric surface abnormalities.

[0036] Preferably, Figure 3 As shown, a plurality of support inserts 4 for fixing the sinker ring 2 are fixed in an annular manner at positions corresponding to the sinker ring 2 on the syringe 1. The support inserts 4 are fixed on one side of the syringe 1 corresponding to the sinker ring 2. Specifically, a plurality of insert legs 41 are extended from the top of the support insert 4 toward the sinker ring 2. The sinker ring 2 is fixed on the insert legs 41 at one end away from the syringe 1. A gap 30 is defined between the sinker ring 2 and the syringe 1. Two insert legs 41 are arranged in a group at the bottom of the gap 30, and each group of insert legs 41 is evenly spaced. A steel ring 42 is further fixed to the bottom of the sinker ring 2. The steel ring 42 is arranged in an annular manner and is fixed to the bottom of the sinker ring 2 by conventional fasteners (such as bolts). The steel ring 42 locks the insert legs 41 to the bottom of the sinker ring 2. By providing the steel ring 42, the connection between the sinker ring 2 and the syringe 1 is made tighter.

[0037] Preferably, in this embodiment, the distance between the two insert high feet 41 of each group is about 4.5 centimeters, and the spacing between the insert high feet 41 of each group can be reasonably set according to actual needs; when the large circular knitting machine is working, the woven cotton wool is easy to fall into the gap 30 between the needle cylinder 1 and the sinker ring 2. The insert high feet 41 of the utility model are evenly spaced at the bottom of the gap 30 between the needle cylinder 1 and the sinker ring 2. The wider spacing between the insert high feet 41 makes it easier to discharge the cotton wool, reduce the accumulation of cotton wool, and reduce the number of times the machine is cleaned, thereby avoiding the cotton wool affecting the quality of the cloth. In addition, by setting the steel ring 42 and the distributed insert high feet 41, the connection between the sinker ring 2, the insert high feet 41 and the needle cylinder 1 is tighter, the vibration of the sinker ring 2 when the machine is running is reduced, and the overall stability of the sinker ring 2 is improved, which can be widely promoted and applied.

[0038] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
