Description

Technical Field

[0001] This invention relates to the field of ring spinning machine technology, and in particular to a ring spinning machine end yarn clearing self-avoiding track car. Background Technology

[0002] When a spinning frame starts producing yarn bobs, the tail yarn needs to be inserted into the end of the bobbin before spinning begins to achieve traction. If the tail yarn is not removed after traction is achieved, the negative pressure in the next process, the automatic feeding winding machine, will cause the head yarn to be wound up along with the tail yarn during spindle production. Therefore, it is necessary to remove the tail yarn. Traditionally, this requires manually removing the tail yarn through a cleaning window after the frame cover is moved up, which has the following disadvantages:

[0003] 1. Due to the limited space in the spinning machine, the operating space of the cleaning trolley overlaps with the trajectory of the cover plate that moves up and down in the spinning machine. When the cover plate moves downward, if the cleaning trolley does not avoid it in time, the cover plate will be blocked by the cleaning trolley, causing a malfunction. 2. The steel wire rope of the cleaning trolley transmits driving force through friction with the drive wheel. The magnitude of the driving force borne by the steel wire rope is the friction force between the steel wire rope and the drive wheel. Over time, the deformation of the steel wire and the wear of the drive wheel will cause the friction force to decrease, thus affecting the quality of yarn removal. 3. The cleaning trolley directly mounts the drive wheel on the output shaft of the motor and increases the friction force by pressing the steel wire rope on one side. This will cause an imbalance of force on the drive wheel, causing the output shaft of the motor to bear radial force, thereby damaging the motor.

[0004] Therefore, how to provide a self-avoiding track car for clearing yarn tails on a spinning machine to improve the quality of yarn tail removal and enhance the durability of the track car has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a self-avoiding track car for clearing tail yarn on a spinning machine, thereby improving the quality of tail yarn clearing and enhancing the durability of the track car.

[0006] This invention is implemented as follows: a self-avoiding track car for clearing yarn on a spinning frame, comprising:

[0007] Two tracks, set parallel to each other;

[0008] Two tail-clearing trolleys are slidably connected to one of the tracks, and are initially located at the left and right ends of the two tracks respectively;

[0009] A drive mechanism is located in the middle of the two tracks and at the ends of the tracks;

[0010] Four guide pulleys are respectively located on the outer sides of both ends of each of the aforementioned tracks;

[0011] Two steel wire ropes, both ends of which are respectively locked on one said tail cleaning trolley, one of which passes through the driving mechanism and two guide pulleys, and the other of which passes through two said guide pulleys;

[0012] The tail cleaning trolley comprises:

[0013] A sliding plate;

[0014] Three guide wheels, which are rotationally connected to the side surface of the sliding plate, are distributed in a triangular shape and match the track;

[0015] Two clamping blocks, which are arranged on the side surface of the sliding plate and located on the left and right sides of the upper guide wheels, clamp the end of one said steel wire rope, respectively;

[0016] A torsional spring hinge, which is vertically arranged on the side surface of the sliding plate and located on the same side of the guide wheels and higher than the guide wheels;

[0017] A tail cleaning yarn steel wire brush, which is arranged on the torsional spring hinge.

[0018] Further, the driving mechanism comprises:

[0019] A bottom plate, which is arranged at the middle part of two said tracks and located at the end part of the track;

[0020] A motor, which is arranged at the bottom end of the bottom plate and whose output shaft passes through the bottom plate upwards;

[0021] A driving wheel, which is arranged at the top end of the bottom plate and connected with the output shaft, and a circle of grooves is arranged at the middle part of the side surface of the driving wheel;

[0022] Two vertical columns, which are vertically arranged at the top end of the bottom plate and symmetrically arranged on the left and right sides of the driving wheel;

[0023] Two eccentric sleeves, which are respectively sleeved on one said vertical column;

[0024] Two clamping wheels, which are respectively sleeved on one said eccentric sleeve;

[0025] Two swing arms, one end of which is respectively sleeved on one said eccentric sleeve;

[0026] A tension spring, two ends of which are respectively connected with the other end of one said swing arm.

[0027] The advantages of the present application are:

[0028] By setting a tail cleaning trolley at the left and right ends of the two tracks respectively, the two ends of the two steel wires are respectively locked on a tail cleaning trolley, one of which passes through a driving mechanism and two guide pulleys, and the other passes through two guide pulleys, so that one tail cleaning trolley moves to the left and the other tail cleaning trolley moves to the right through a driving mechanism, that is, the tail yarns on both sides are simultaneously cleaned, and the torsional spring hinge provided on the tail cleaning trolley can automatically avoid the cover of the spinning frame to avoid causing a fault; by setting a tension spring to pull the two swing arms on the driving mechanism, since the deformation amount of the tension spring is relatively large, when the steel wire is deformed or the groove of the driving wheel is worn, the tension spring will automatically compensate for the loss amount to drive the eccentric sleeve, so that the steel wire maintains sufficient driving force to ensure the quality of tail yarn cleaning; by symmetrically setting the upright columns on the left and right sides of the driving wheel of the driving mechanism, the two swing arms are pulled tight by the same tension spring, so that the same force is received, the radial force of the driving wheel is balanced, the radial burden of the motor is reduced, the loss of the motor is reduced, and finally the quality of tail yarn cleaning is greatly improved, and the durability of the track vehicle is greatly improved.

DETAILED DESCRIPTION

[0037] The general idea of the technical solutions in the embodiments of the present application is as follows: two tail yarn cleaning trolleys 2 are driven by a driving mechanism 3 to move towards each other on a track 1, and simultaneously, tail yarns on both sides are cleaned, and a torsional spring hinge 24 arranged on the tail yarn cleaning trolley 2 is used to automatically avoid the cover plate 61 of the spinning frame 6, so as to avoid causing a fault and improve the durability of the track trolley 100; a pulling spring 38 is arranged on the driving mechanism 3 to pull two swing arms 37, and since the deformation amount of the pulling spring 38 is relatively large, when the steel wire rope 5 is deformed or the groove 331 of the driving wheel 33 is worn, the pulling spring 38 will automatically compensate for the loss to ensure that the steel wire rope 5 has sufficient driving force, so as to improve the quality of tail yarn cleaning; the driving mechanism 3 is symmetrically provided with a stand 34 and a swing arm 37, and the two swing arms 37 are pulled tight by the same pulling spring 38, so that the radial force of the driving wheel 33 is balanced to reduce the radial burden of the motor 32, thereby improving the durability of the track trolley 100.

[0038] Please refer to Figures 1 to 5 The preferred embodiment of the track trolley 100 for automatically avoiding tail yarn cleaning of a spinning frame of the present application comprises:

[0039] Two tracks 1 are arranged in parallel and are used for limiting sliding of the tail yarn cleaning trolleys 2.

[0040] Two tail yarn cleaning trolleys 2 are respectively connected with a track 1 in a sliding manner, and are initially located at left and right ends of the two tracks 1, i.e., are distributed in a staggered manner at the head and tail, and are used for cleaning tail yarns of the spinning frame 6, when one side of the tail yarn cleaning trolley 2 moves left from the original position, the other side of the tail yarn cleaning trolley 2 synchronously moves right from the original position, when one side of the tail yarn cleaning trolley 2 completes one reciprocating tail yarn cleaning movement, the other side of the tail yarn cleaning trolley 2 also completes one reciprocating tail yarn cleaning movement.

[0041] A driving mechanism 3 is arranged in the middle of the two tracks 1 and at the end of the track 1, and is used for driving the tail yarn cleaning trolleys 2 to slide on the track 1.

[0042] Four guide pulleys 4 are respectively arranged outside the two ends of each track 1, i.e., are symmetrically installed at four corners of the spinning frame 6.

[0043] Two steel wire ropes 5 are respectively locked at two ends of one tail yarn cleaning trolley 2, one of which passes through the driving mechanism 3 and the two guide pulleys 4, and the other of which passes through the two guide pulleys 4, and are used for transmitting power from the driving mechanism 3 to the tail yarn cleaning trolley 2.

[0044] The tail yarn cleaning trolley 2 comprises:

[0045] A sliding plate 21.

[0046] Three guide wheels 22 are rotatably connected to the side of the sliding plate 21, are triangularly distributed, and are matched with the track 1, so that the cleaning tail trolley 2 can move on the track 1;

[0047] Two clamping blocks 23 are arranged on the side of the sliding plate 21 and are located on the left and right sides of the upper guide wheel 22, and clamp the end of the steel wire rope 5 respectively;

[0048] A torsion spring hinge 24 is vertically arranged on the side of the sliding plate 21 and is located on the same side of the guide wheel 22 and higher than the guide wheel 22;

[0049] A cleaning tail yarn steel wire brush 25 is arranged on the torsion spring hinge 24. When the cover plate 61 of the spinning frame 6 moves downward, if the cleaning tail yarn steel wire brush 25 runs to the bottom of the cover plate 61, the cover plate 61 will press the cleaning tail yarn steel wire brush 25 downward to avoid the cover plate 61, and when the cover plate 61 moves upward, the torsion spring hinge 24 will automatically lift the cleaning tail yarn steel wire brush 25 upward to continue cleaning the tail yarn of the yarn tube.

[0050] The driving mechanism 3 comprises:

[0051] A bottom plate 31 is arranged at the middle part of the two tracks 1 and is located at the end part of the track 1;

[0052] A motor 32 is arranged at the bottom end of the bottom plate 31, and the output shaft 321 passes through the bottom plate 31 from bottom to top;

[0053] A driving wheel 33 is arranged at the top end of the bottom plate 31 and is connected with the output shaft 321, and a groove 331 is arranged on the side surface of the middle part of the driving wheel 33; the groove 331 is used for limiting the steel wire rope 5;

[0054] Two vertical columns 34 are vertically arranged at the top end of the bottom plate 31 and are symmetrically arranged on the left and right sides of the driving wheel 33;

[0055] Two eccentric sleeves 35 are respectively sleeved on the vertical column 34 and can freely rotate around the vertical column 34;

[0056] Two clamping wheels 36 are respectively sleeved on the eccentric sleeve 35 and can freely rotate around the outer circle of the eccentric sleeve 35; the steel wire rope 5 alternately passes through one of the clamping wheels 36, the driving wheel 33 and the other clamping wheel 36;

[0057] Two swing arms 37 are respectively sleeved on one end of the eccentric sleeve 35 and are located above the clamping wheel 36 and synchronously rotate with the eccentric sleeve 35;

[0058] A tension spring 38, both ends are connected with the other end of a swing arm 37 respectively. Because the hole of the eccentric sleeve 35 is eccentric, when the tension spring 38 pulls the swing arm 37 inwards, the swing arm 37 will have a tendency to move the left eccentric sleeve 35 to the right, and the right eccentric sleeve 35 to the left, thereby driving the clamping wheel 36 to press the steel wire rope 5 on the driving wheel 33.

[0059] The working principle of the present application is:

[0060] The driving mechanism 3 drives the driving wheel 33 to rotate through the motor 32, the driving wheel 33 pulls the steel wire rope 5 through the friction force of the groove 331, so that the steel wire rope 5 pulls one of the tail cleaning trolleys 2 to move left and the other tail cleaning trolley 2 to move right, and the tail cleaning trolley 2 moves through the tail cleaning steel wire brush 25 to perform the operation of removing the tail yarn of the spinning frame 6, when the cover plate 61 of the spinning frame 6 moves downward, the tail cleaning steel wire brush 25 automatically avoids through the torsional spring hinge 24.

[0061] In summary, the present application has the following advantages:

[0062] By setting a tail cleaning trolley at the left and right ends of the two tracks, locking the two ends of the two steel wire ropes on the tail cleaning trolleys respectively, one of the steel wire ropes passing through the driving mechanism and two guide pulleys, and the other passing through two guide pulleys, one driving mechanism can drive one tail cleaning trolley to move left and the other to move right, that is, simultaneously removing the tail yarn on both sides, and the torsional spring hinge on the tail cleaning trolley can automatically avoid the cover plate of the spinning frame, avoiding failure; By setting a tension spring on the driving mechanism to pull the two swing arms, because the deformation of the tension spring is relatively large, when the steel wire rope deforms or the groove of the driving wheel wears, the tension spring will automatically compensate for the loss, so that the steel wire rope maintains sufficient driving force to ensure the quality of tail yarn removal; By setting a stand on the left and right sides of the driving wheel of the driving mechanism, and setting two swing arms pulled by the same tension spring, the force received is the same, so that the radial force of the driving wheel is balanced, reducing the radial burden of the motor, thereby reducing the loss of the motor, ultimately greatly improving the quality of tail yarn removal and the durability of the rail car.

[0063] Although the specific embodiments of the present application are described above, those skilled in the art should understand that the specific examples described are only illustrative, and are not intended to limit the scope of the present application, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present application should be covered within the scope of the claims of the present application.
