Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to a yarn cutting device for a textile machine. Background Art

[0002] When the yarn is processed by a special textile machine, it needs to be cut so that it can be woven according to the needs. However, the existing cutting mechanisms all cut directly without stabilizing the yarn to be cut, resulting in poor cutting effect, thus affecting subsequent textile operations.

[0003] According to the published patent 202221243621.9, a yarn cutting device for a textile machine includes a cutting table and yarn, an L-shaped installation box is fixedly installed on the left end of the upper wall of the cutting table, and an installation groove is opened on the right wall of the vertical end of the installation box, a telescopic rod is fixedly installed on the top wall of the installation groove, a movable rod is fixedly installed on the lower end face of the telescopic rod, a hydraulic cylinder is fixedly installed on the upper wall of the horizontal end of the installation box, and the output end of the hydraulic cylinder passes through the upper wall of the horizontal end of the installation box and a hydraulic rod is fixedly installed on the output end. The yarn is clamped on the upper side of the cutting table by the clamping mechanism, the hydraulic cylinder is turned on, and the hydraulic rod moves downward under the action of the output end of the hydraulic cylinder, and the hydraulic rod begins to move toward the direction of the second blade, and finally cuts the yarn. In this way, under the action of the clamping mechanism, the yarn can be firmly fixed when cutting the yarn, thereby ensuring the tip effect of the yarn. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the yarn is clamped on the upper side of the cutting table by the clamping mechanism, the hydraulic cylinder is turned on, and the hydraulic rod moves downward under the action of the output end of the hydraulic cylinder, the hydraulic rod begins to move toward the second blade The yarn moves in the direction of the cutting end, and finally the yarn cutting end is cut. In this way, the yarn can be firmly fixed under the action of the clamping mechanism when the yarn is cut, thereby ensuring the tip effect of the yarn and facilitating subsequent work. During use, the traditional textile machine uses a yarn cutting device to limit and fix the yarn, but the yarn is easily piled up during the moving cutting process, causing the cut part of the yarn to pile up and bend, affecting the cutting effect. Moreover, when cutting the yarn, the test paper fixes the positions of the two ends of the yarn, and the yarn is not horizontal on the platform surface. When cutting the yarn, it will affect the accuracy of the yarn cutting. For this reason, it is necessary to design a new technical solution to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a yarn cutting device for a textile machine to solve the problem that the current traditional yarn cutting device for a textile machine limits and fixes the yarn, but the yarn is easily piled up during the moving cutting process, resulting in the piled and bent cut parts of the yarn, which affects the cutting effect. Moreover, when cutting the yarn, the test paper fixes the positions of the two ends of the yarn, and the yarn is not horizontal on the platform surface. When cutting the yarn, it will affect the technical problem of the accuracy of yarn cutting.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a yarn cutting device for a textile machine, including a device plate body, and also including:

[0006] Two limit frame plates are respectively installed on both sides of the top of the device plate body;

[0007] A wire pulling mechanism is installed on the top of the two limit frame plates, the wire pulling mechanism comprises a first electric telescopic cylinder, a limit frame plate is installed at the bottom of the first electric telescopic cylinder, and the bottom of the first electric telescopic cylinder extends into the limit frame plate;

[0008] A concave frame plate is fixed to one end of the first electric telescopic cylinder located in the limiting frame plate, and a rotating roller is arranged inside the concave frame plate.

[0009] Preferably, a connecting rod passes through the interior of the rotating roller, and the connecting rod is fixedly connected to the penetration position of the rotating roller.

[0010] Preferably, a motor shaft is fixed to one side of the connecting rod, an end of the motor shaft away from the connecting rod passes through a concave frame plate and is connected to the motor, and a concave frame plate is installed on one side of the motor.

[0011] Preferably, a bearing is rotatably connected to the other side of the connecting rod, and a concave frame plate is installed at one end of the bearing away from the connecting rod.

[0012] Preferably, an L-shaped plate body is fixed on one side of the top of the device plate body, a second electric telescopic cylinder is installed on one side of the bottom of the L-shaped plate body, and a cutting knife is fixed on the bottom of the second electric telescopic cylinder.

[0013] Preferably, connecting plates are fixed at both the front and rear ends of the cutting knife, a pressure cylinder is installed at the bottom of the connecting plate body, a pressure rod passes through the bottom of the pressure cylinder, a movable plate is fixed at one end of the pressure rod located in the pressure cylinder, a spring is fixed on the top of the movable plate, a pressure cylinder is fixed on the top of the spring, and a pressure plate is fixed at the bottom of the pressure rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines an electric telescopic cylinder, a concave frame plate and a rotating roller. After the yarn passes through the two limit frame plates, the electric telescopic cylinder can be used to drive the concave frame plate and the rotating roller to move downward to limit and fix the two ends of the yarn. Moreover, when cutting the yarn, it can also drive two motors, which respectively drive the two rotating rollers to rotate outward, so that the yarn at the cutting position can be straightened, and the yarn can be cut in a straightened state, avoiding the situation of yarn accumulation and bending during the cutting process. This solves the technical problem that the traditional yarn cutting device for textile machines limits and fixes the yarn, but the yarn is easily accumulated together during the moving cutting process, resulting in accumulation and bending of the cut part of the yarn, which affects the cutting effect.

[0016] 2. The utility model connects the plate body, the pressure cylinder and the pressure plate. When the cutting knife moves down to cut the yarn, the pressure plate will first contact the top of the yarn and flatten the yarn. Since the pressure plate is connected to the pressure rod, it can squeeze the spring to move the pressure cylinder and the cutting knife downward to cut the flattened yarn. This solves the technical problem that when cutting the yarn, the test paper fixes the positions of the two ends of the yarn, and the yarn is not horizontal on the platform surface, which will affect the accuracy of yarn cutting.
