Description

Technical Field

[0001] The invention relates to the field of cotton carding machines, in particular to a transmission system and a cotton carding machine for preventing a cylinder and a licker-in roller from colliding. Background Art

[0002] The carding machine is a kind of textile machinery that plays an important role in the cotton spinning process. It can comb, remove impurities and mix cotton rolls, and finally make the mixed fibers into uniform cotton strips. The cylinder and licker-in roller are the most important carding parts of the carding machine. The existing cylinder and licker-in roller often wear out during long-term use. After wear, the cylinder and licker-in roller have large radial errors, which leads to vibration during the working process. This also accelerates the wear of the cylinder shaft and licker-in roller shaft to a certain extent. Once the wear increases, such as Figure 1 As shown, the winding direction of the belt of the transmission system of the cylinder and the licker-in roller is Figure 1 As shown in the figure, the pulling force of the belt on the cylinder drive wheel and the licker-in roller drive wheel is relative. Therefore, when the cylinder shaft and the licker-in roller shaft are greatly worn, the cylinder and the licker-in roller will collide due to the pulling force of the belt. Once the collision occurs, the carding machine must be stopped and repaired, which seriously affects the working efficiency of the carding machine and affects the subsequent cotton spinning process.

[0003] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0004] The present application aims to solve the problem that the cylinder and the licker-in roller in the transmission system of the existing carding machine have opposite force directions under the belt drive, so the cylinder drive wheel and the licker-in roller drive wheel may collide due to wear, so a transmission system and a carding machine are designed to prevent the cylinder and the licker-in roller from colliding. The specific embodiment is as follows:

[0005] A transmission system for preventing a cylinder and a licker-in roller from colliding, comprising:

[0006] A cylinder transmission wheel, which is rotatably arranged on the frame;

[0007] At least two reversing wheels, which are also arranged on the frame and are arranged in a triangle with the cylinder drive wheel;

[0008] The licker-in roller transmission wheel is arranged in a plane surrounded by a straight line where two reversing wheels are located, and the straight line where the two reversing wheels are located is perpendicular to a line connecting the two reversing wheels at the same time;

[0009] The belt passes through the cylinder drive wheel, one of the reversing wheels, the licker-in roller drive wheel and the other reversing wheel in sequence to form a closed-loop belt.

[0010] Preferably, the axis height of the licker-in roller transmission wheel is lower than the axis height of the cylinder transmission wheel, so that the overlap between the licker-in roller and the cylinder can be reduced from the perspective of the deadweight of the licker-in roller transmission wheel, thereby reducing the collision area.

[0011] Further preferably, it also includes:

[0012] A tensioning wheel is arranged between one of the reversing wheels and the licker-in roller transmission wheel.

[0013] Preferably, an adjustment slot is provided on the frame, and the tensioning wheel is arranged in the adjustment slot. The tensioning wheel can adjust the position in the adjustment slot through the connecting part. By adjusting the tensioning wheel, the force of the belt acting on the licker-in roller transmission wheel can be adjusted to avoid the belt being too loose so that there is no force between the belt and the licker-in roller transmission wheel, which will fail to avoid the collision between the licker-in roller and the cylinder.

[0014] Preferably, the adjustment direction of the adjustment groove is perpendicular to the belt direction between the licker-in roller transmission wheel and one of the reversing wheels.

[0015] Preferably, the connecting portion is a stud, the bare rod section of the stud is connected to the tensioning wheel through a bearing, the threaded section of the stud passes through an adjustment groove and is connected to a nut, and the position of the tensioning wheel can be adjusted by loosening the nut.

[0016] Preferably, a first transmission wheel is provided at one end of the rotating shaft of the licker-in roller transmission wheel, the first transmission wheel is connected to the second transmission wheel through a chain transmission, and the angle between the line between the centers of the first transmission wheel and the second transmission wheel and the line between the centers of the cylinder transmission wheel and the licker-in roller transmission wheel is not less than 90°. At this time, the force direction of the first transmission wheel is the same as the force direction of the cylinder transmission wheel or the first transmission wheel has a component force in the same direction as the force direction of the cylinder transmission wheel, which can further avoid collision between the cylinder and the licker-in roller at the moment of belt breaking.

[0017] Preferably, the angle between the line between the centers of the first transmission wheel and the second transmission wheel and the line between the centers of the cylinder transmission wheel and the licker-in roller transmission wheel is 180°. At this time, the force direction of the first transmission wheel and the force direction of the cylinder are in the same direction, which can ensure that the force acting on the first transmission wheel is maximized and enable the force to act more specifically in the collision contact direction of the cylinder and the licker-in roller.

[0018] Preferably, the first transmission wheel and the second transmission wheel are pulleys, and a belt is connected between the first transmission wheel and the second transmission wheel.

[0019] A cotton carding machine comprises the transmission system for preventing the cylinder and the licker-in roller from colliding, and utilizes the transmission system to realize power transmission.

[0020] The present invention can change the situation that the traditional force directions of the cylinder transmission wheel and the licker-in roller transmission wheel are opposite to each other through the transmission system, so that the traditional force directions of the cylinder transmission wheel and the licker-in roller transmission wheel are the same, and can prevent the cylinder and the licker-in roller from colliding after the rotating shafts of the cylinder and the licker-in roller are worn, thereby reducing the maintenance times of the transmission system and ensuring the normal operation of the carding machine.

DETAILED DESCRIPTION

[0025] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0026] like Figure 1-3As shown, a transmission system and a cotton carding machine for preventing a cylinder and a licker-in roller from colliding include a cylinder transmission wheel 2, two reversing wheels 4, a licker-in roller transmission wheel 3 and a belt 5. Of course, it is inevitable that in actual operation, there must be a driving motor, which is connected to the licker-in roller transmission wheel 3 in this embodiment (the driving motor is not shown in this embodiment), and the licker-in roller transmission wheel 3 drives the cylinder transmission wheel 2 and the reversing wheel 4 through the belt 5 to realize transmission; the cylinder transmission wheel 2 is rotatably arranged on the frame 1 through the rotating shaft 6 and the bearing 13, and the two reversing wheels 4 are also arranged on the frame 1 through the rotating shaft 6 and the bearing, and the licker-in roller transmission wheel 3 is also rotatably arranged on the frame 1 through the bearing, the licker-in roller transmission wheel 3, the rotating shaft 6 of the two steering wheels 4 and the rotating shaft of the cylinder transmission wheel 2 are arranged parallel to each other, and the two reversing wheels 4 are arranged in a triangle with the cylinder transmission wheel 2, and the licker-in roller transmission wheel 3 is arranged in a plane surrounded by the straight lines where the two reversing wheels 4 are located, where the straight line is perpendicular to the line between the two reversing wheels 4, and is located on the side of the line between the two reversing wheels 4 close to the cylinder transmission wheel 2; the belt 5 successively passes around the cylinder transmission wheel 2, one of the reversing wheels 4, the licker-in roller transmission wheel 3 and the other reversing wheel 4 to form a closed-loop belt 5. In this way, the force exerted by the belt 5 on the cylinder drive wheel 2 and the force exerted by the belt 5 on the licker-in roller drive wheel 3 are in the same direction. Therefore, when the wear amount of the rotating shaft of the cylinder drive wheel 2 and the rotating shaft of the licker-in roller drive wheel 3 is greater than the distance between the cylinder and the licker-in roller 14, the collision between the cylinder and the licker-in roller 14 is avoided; the number of maintenance times when the transmission system is working is reduced, and the normal operation of the entire process of the carding machine is guaranteed.

[0027] Furthermore, when the belt 5 becomes loose, in order to reduce the collision area between the licker-in roller 14 and the cylinder and reduce the degree of collision, the axis height of the licker-in roller transmission wheel 3 is lower than the axis height of the cylinder transmission wheel 2. In this way, after the rotating shaft of the licker-in roller transmission wheel 3 is worn, the overlapping part between the licker-in roller 14 and the cylinder will be reduced under the action of its own gravity, thereby reducing the degree of collision.

[0028] Further, a tensioning wheel 8 is provided between one of the reversing wheels 4 and the licker-in roller transmission wheel 3. The tensioning wheel 8 is provided on the adjustment slot 7 on the frame 1. The tensioning wheel 8 is fixed to the bare rod end of a stud 9 through a bearing. The threaded end of the stud 9 passes through the adjustment slot 7 and is threadedly connected with a nut 13. When the force between the belt 5 and the licker-in roller transmission wheel 3 needs to be adjusted, it is achieved by adjusting the position of the tensioning wheel 8, specifically by loosening the nut 13 and manually adjusting the position of the stud 9 in the adjustment slot 7. After the adjustment is completed, the tensioning wheel 8 is fixed by tightening the nut 13. By providing the tensioning wheel 8 and setting it to be adjustable, the force of the belt 5 acting on the licker-in roller transmission wheel 3 can be adjusted according to needs or according to the wear amount of the rotating shaft of the licker-in roller transmission wheel 3 during the working process, thereby ensuring that when the wear amount of the rotating shaft of the licker-in roller transmission wheel 3 exceeds the spacing between the cylinder and the licker-in roller 14, the force of the belt 5 on the licker-in roller transmission wheel 3 can prevent it from colliding.

[0029] Furthermore, the adjustment direction of the adjustment groove 7 is perpendicular to the direction of the belt 5 between the licker-in roller transmission wheel 3 and one of the reversing wheels 4, so that the tensioning wheel 8 can move a shorter distance to achieve a greater tensioning effect.

[0030] Alternatively, in one embodiment, two, three or more tension wheels 8 may be provided.

[0031] Furthermore, in order to prevent the cylinder from colliding with the licker-in roller 14 when the belt 5 breaks, a first transmission wheel 11 is provided at one end of the licker-in roller transmission wheel 3, and the first transmission wheel 11 is connected to the second transmission wheel 10 through a transmission medium. The angle between the line between the first transmission wheel 11 and the second transmission wheel 10 and the line between the center of the cylinder transmission wheel 2 and the licker-in roller transmission wheel 3 is not less than 90°. At this time, the force direction of the first transmission wheel 11 is the same as the force direction of the cylinder transmission wheel 2 or the first transmission wheel 11 has a component force in the same direction as the force direction of the cylinder transmission wheel 2, which can further avoid the collision between the cylinder and the licker-in roller 14 when the belt 5 breaks. Preferably, in order to ensure that the force acting on the first transmission wheel 11 is maximized, the angle between the line between the centers of the first transmission wheel 11 and the second transmission wheel 10 and the line between the cylinder transmission wheel 2 and the licker-in transmission wheel 3 is set to 180°. At this time, the force direction of the first transmission wheel 11 and the force direction of the cylinder transmission wheel 2 are in the same direction and on the same line, which can more effectively and specifically prevent collisions.

[0032] Furthermore, the first transmission wheel 11 and the second transmission wheel 10 are pulleys, and a belt 5 is connected between the first transmission wheel 11 and the second transmission wheel 10. The pulley is more stable than the sprocket and can match the transmission mode of the transmission system.

[0033] The present application also protects a carding machine used with the above transmission system, through which power transmission is achieved.

[0034] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0035] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
