Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a tube-changing mechanism for a textile winding machine. Background Technique

[0002] In the textile industry, the main function of a winding machine is to process yarn in the form of a tube into a cylindrical or conical package. The package has the advantages of large volume and good forming effect. Therefore, the winding process of yarn is one of the indispensable processes in the textile industry.

[0003] For the existing tube-changing mechanism of a winding machine, for example, a tube-changing device of a winding machine disclosed in the utility model patent with the application number 201420512554.5, its main structure includes a guide post. The tube yarn storage is provided with eight yarn storage positions evenly distributed in a circumferential direction, and each yarn storage position contains a tube yarn. A through hole is provided on the chassis, and a moving frame is arranged directly below the through hole. The moving frame is movably arranged up and down on the guide post. The guide post is vertically fixed between the chassis and the base. A vertical driving cylinder is arranged between the base and the moving frame. Two clamping blocks are symmetrically arranged on the moving frame. The outside of the clamping block is connected to a releasing cylinder, and a supporting column is fixed on the base. When in use, the driving motor drives the first pulley to rotate. The first pulley drives the second pulley through a belt, so as to drive the tube yarn storage to rotate intermittently at equal angles. After each rotation of the tube yarn storage, the tube yarn in the yarn storage position falls from the through hole of the chassis. During the falling process of the tube yarn, the releasing cylinder pushes the clamping block to move inwards, and the clamping block clamps the tube yarn. The driving cylinder drives the moving frame to move downwards, and the tube yarn moves downwards accordingly. When the moving frame moves down and touches the trigger switch, the trigger switch controls the movement of the guiding motor. The guiding motor drives the incomplete gear to rotate. The incomplete gear drives the lower end of the bent plate to move outwards through a connecting rod. The bent plate rotates around the hinge point in the middle, and the guiding plate at the upper end of the bent plate moves inwards.

[0004] However, the yarn is easily contaminated during the movement of the tube yarn. Most of the existing tube-changing mechanisms are difficult to clean it, which affects the quality. Moreover, most of the empty tubes still need to be removed manually, which is very troublesome. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a tube-changing mechanism for a textile winding machine, which not only cleans the tube yarn before splicing, prevents the yarn from being contaminated and affecting subsequent use, but also can drive the automatic feeding of the empty tube, improving the working efficiency.

[0006] A tube-changing mechanism for a textile winding machine of the present utility model includes a blanking mechanism; it further includes a lifting mechanism, a cleaning mechanism, and a feeding mechanism. The lifting mechanism is installed on the blanking mechanism and drives the tube yarn to descend. The cleaning mechanism is installed on the lifting mechanism and cleans the tube yarn. The feeding mechanism is installed on the blanking mechanism and drives the tube yarn to move. When the blanking mechanism is started, after the blanking mechanism discharges the empty tube and resets, at the same time, the blanking mechanism drives the feeding mechanism to rotate, and the feeding mechanism throws the tube yarn into the cleaning mechanism. The tube yarn descends and is impacted and vibrated, and the cleaning mechanism extracts the dust and wool yarn that fall off due to vibration. Then, the cleaning mechanism conveys the tube yarn to the lifting mechanism, and the lifting mechanism drives the tube yarn to move to the blanking mechanism for convenient new round of splicing.

[0007] Preferably, the blanking mechanism includes a workbench, a servo motor, a reducer, a first rotating shaft, and a positioning rod. The workbench is installed on the ground, and a discharge groove is opened on the workbench. The servo motor is installed on the workbench, the reducer is installed on the workbench, the first rotating shaft is rotatably installed on the workbench and is longitudinally connected to the reducer, and the positioning rod is installed on the first rotating shaft. When there is no yarn on the tube sleeved on the positioning rod, the servo motor is started, and the servo motor drives the first rotating shaft to rotate through the reducer, making the positioning rod tilt downward, facilitating the natural fall of the empty tube from the positioning rod.

[0008] Preferably, a resilient turntable is installed on the first rotating shaft. When the empty tube falls off the positioning rod, the reducer stops driving the first rotating shaft, and the resilient turntable drives the first rotating shaft to rotate in the reverse direction and reset, facilitating the reception of subsequent tube yarn.

[0009] Preferably, the lifting mechanism includes two groups of guide rods, a support plate, two groups of first electric cylinders, a support plate, and an arc-shaped backing plate. The bottoms of the two groups of guide rods are connected to the top of the workbench. The support plate is installed on the two groups of guide rods. The two groups of first electric cylinders are both installed on the support plate. The support plate is slidably installed on the two groups of guide rods and is connected to the bottoms of the two groups of first electric cylinders. The arc-shaped backing plate is installed on the support plate. The tube yarn falls onto the arc-shaped backing plate, and the two groups of first electric cylinders push the support plate downward. The support plate drives the arc-shaped backing plate and the tube yarn to descend, so that the tube yarn is inserted onto the positioning rod, making the falling process of the tube yarn more stable.

[0010] Preferably, the arc-shaped backing plate is made of rubber. Rubber has a certain elasticity, which can slow down the impact force of the tube yarn falling from the cleaning mechanism onto the arc-shaped backing plate, and rubber has a large friction force, which can enhance the lifting effect on the tube yarn.

[0011] Preferably, the cleaning mechanism includes a cleaning cylinder, two sets of second electric cylinders, two sets of sliding plates, an air pump, an air extraction pipe, and a sewage discharge pipe. The cleaning cylinder is installed on the support plate. A through hole is provided on the support plate. The two sets of second electric cylinders are respectively installed on the two sets of guide rods. The two sets of sliding plates are both slidably installed in the through hole of the support plate and are respectively connected to the two sets of support plates. The bottom end of the air pump is connected to the top end of the workbench. The air extraction pipe is installed on the air pump and is communicated with the inside of the cleaning cylinder. The sewage discharge pipe is installed on the air pump. The tube yarn falls from the feeding mechanism into the cleaning cylinder. During the falling process and when hitting the two sets of sliding plates, the dust on the tube yarn vibrates and falls and flies. The air pump is started. The air pump extracts the dust in the cleaning cylinder through the air extraction pipe and discharges it through the sewage discharge pipe. Then, the two sets of second electric cylinders pull the two sets of sliding plates to gradually move away, facilitating the tube yarn to fall onto the arc-shaped backing plate.

[0012] Preferably, the feeding mechanism includes a top plate, a turntable, a second rotating shaft, a first pulley, a transmission shaft, a second pulley, and a belt. The bottom end of the top plate is connected to the top ends of the two sets of guide rods. A discharge port is provided on the top plate. The turntable is rotatably installed on the top plate. Multiple placement grooves are provided on the turntable. The second rotating shaft is rotatably installed on the turntable. The first pulley is installed on the second rotating shaft. The transmission shaft is rotatably installed on the speed reducer. The second pulley is installed on the transmission shaft. The belt is tensioned and installed on the first pulley and the second pulley. Multiple tube yarns are placed in the placement grooves of the turntable. The speed reducer drives the transmission shaft to rotate. The transmission shaft drives the second pulley to rotate. The second pulley drives the first pulley and the second rotating shaft to rotate through the belt. The second rotating shaft drives the turntable to rotate. The turntable drives the tube yarn to rotate. The tube yarn falls into the cleaning cylinder through the discharge port of the top plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The feeding mechanism is started. After the feeding mechanism discharges the empty tubes and resets, at the same time, the feeding mechanism drives the feeding mechanism to rotate. The feeding mechanism delivers the tube yarn into the cleaning mechanism. The tube yarn descends and is impacted and vibrated. The cleaning mechanism extracts the dust and wool yarn that vibrate and fall. Then, the cleaning mechanism transports the tube yarn to the lifting mechanism. The lifting mechanism drives the tube yarn to move to the feeding mechanism for a new round of splicing. Brief Description of the Drawings
