[0023] The pressing plate on the existing circular knitting machine triangular seat is fixed when in use. Therefore, when the needle sleeve on the syringe fails during operation, it is easy to cause serious impact on the needle sleeve and cause injection, and cause damage to the syringe. In order to solve the above technical problems, this case proposes the following technical solutions:

[0024] Reference Figures 1 to 6 As shown, a needle sleeve pressing plate for a large circular knitting machine for a cylinder, the structure of which includes: a triangular seat 1, a pressing plate assembly 2 arranged on the top of the triangular seat 1, the pressing plate assembly 2 including a fixed seat 21 fixed on the triangular seat 1, an upper guard plate 22 is arranged on the top of the fixed seat 21, a slide rail 221 is penetrated through the top of the upper guard plate 22, a positioning bolt 23 that passes through the slide rail 221 and is connected to the fixed seat 21 is arranged on the upper guard plate 22, the upper guard plate 22 can move forward and backward along the slide rail 221 relative to the positioning bolt 23, the upper guard plate 22 can move forward and backward along the slide rail 221 relative to the positioning bolt 23, the upper guard plate 22 is fixed with a limiting plate 24 by bolts on the side of the upper guard plate 22 facing away from the needle cylinder of the circular knitting machine, the limiting plate 24 is installed on the side of the fixed seat 21 facing away from the needle cylinder of the circular knitting machine through a guide bolt 25, the limiting plate 24 is provided with a guide hole 241 that moves forward and backward along the guide bolt 25, the guide bolt 25 passes through the guide hole 241 and is connected to the fixed seat 21, and a top spring 26 is sleeved between the end of the guide bolt 25 facing away from the fixed seat 21 and the limiting plate 24;

[0025] The slide rail 221 is formed on the upper guard plate 22 and extends radially along the needle cylinder of the circular knitting machine. The fixing seat 21 is provided with a fixing hole 211 connected to the bottom of the positioning bolt 23, and the fixing hole 211 is arranged corresponding to the slide rail 221.

[0026] The fixing seat 21 is a long strip structure, and both ends are connected to the top of the triangular seat 1 by bolts, which is convenient for disassembly and maintenance;

[0027] The mounting mechanism of the pressure plate of the upper needle disk triangular seat is the same as that of the pressure plate of the lower needle disk triangular seat. Here, the mounting mechanism of the pressure plate of the lower needle disk triangular seat is used as an example for explanation. Therefore, since the positioning bolt 23 is in the slide rail 221 and the bottom is connected to the fixed seat 21, and the limit plate 24 is fixed to the side of the upper guard plate 22 away from the syringe, and the guide bolt 25 passes through the guide hole 241 and is connected to the fixed seat 21, and the top spring 26 is sleeved between the guide bolt 25 and the limit plate 24, therefore, when in use, the upper guard plate 22 can pop outward along the slide rail 221 relative to the positioning bolt 23. At the same time as the upper guard plate 22 pops outward, the limit plate 24 moves outward along the guide bolt 25 through the guide hole 241 and squeezes the top spring 26. Therefore, the upper guard plate 22 adopts a movable installation method. When the syringe needle sleeve fails due to wear, the upper guard plate can pop outward along the slide rail relative to the positioning bolt, which effectively reduces the risk of serious impact on the needle sleeve for injection and protects the syringe from damage.

[0028] In order to facilitate the adjustment of the upper guard plate 22 and to facilitate the setting of the upper guard plate 22 according to actual conditions, a threaded hole 242 is formed on the limit plate 24, and an adjusting bolt 27 connected to the threaded hole 242 is provided on the limit plate 24. An adjusting nut 28 is connected to the head of the adjusting bolt 27, and the tail of the adjusting bolt 27 is close to the side of the fixing seat 21 away from the needle cylinder of the circular knitting machine;

[0029] When in use, the push spring 26 urges the limit plate 24 to be close to the fixed seat 21, and at the same time the limit plate 24 drives the inner side of the upper guard plate 22 to fit the surface of the syringe. When the position of the upper guard plate 22 needs to be adjusted, the adjusting nut 28 can be rotated to a suitable position according to actual needs, and then the adjusting bolt 27 and the threaded hole 242 can be locked. After locking, the adjusting nut 28 fits the surface of the limit plate 24, and the tail of the adjusting bolt 27 is close to the fixed seat 21, thereby completing the front and rear adjustment of the upper guard plate 22.

[0030] Furthermore, the limit plate 24, guide bolt 25, push spring 26, adjustment bolt 27, and adjustment nut 28 are provided in two groups, and are respectively located at the two ends of the upper guard plate 22 on the side away from the circular knitting machine needle cylinder, and since the slide rail 221 is arranged in the middle of the upper guard plate 22, when in use, the upper guard plate 22 can not only move back and forth along the slide rail 221 relative to the positioning bolt 23, but also rotate around the positioning bolt 23. Therefore, the adjusting nuts 28 and the adjusting bolts 27 on the limit plates 24 at both ends can be adjusted respectively, so that the upper guard plate 22 can rotate around the positioning bolt 23, and the angle can be adjusted to make the upper guard plate 22 fit better with the outer surface of the needle cylinder.

[0031] A dustproof plate 29 is provided between the bottom of the fixing seat 21 and the top of the triangular seat 1 to prevent cotton wool and dust from entering the gap between the triangular seat and the needle cylinder, thereby ensuring the normal operation of the large circular knitting machine.

[0032] The dustproof plate 29 is provided with mounting holes corresponding to the fixing seat 21 , so that the bolts of the fixing seat 21 can pass through and be locked with the triangular seat 1 .

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
