The main function of the combing machine is to remove shorter fibers, remove tangled particles (cotton neps, hair particles, grass scraps, cocoon skin, etc.) in the fibers, make the fibers further straight and parallel, and finally make combed slivers with relatively uniform thickness. The yarn reel is replaced during the use of the combing machine to facilitate continuous feeding for textile work.

[0003] However, in actual use, rolls can only be changed one by one, and multiple rolls cannot be stored at one time for continuous roll change, which results in low roll change efficiency. In addition, the roll stability is low during the roll change process, and it cannot play a limiting role, resulting in a large roll swing, which is not conducive to the use of the combing machine, reduces the working efficiency of the combing machine, and has poor practicality. The patent number is CN215251409U, and the name is an automatic roll changing device for a combing machine. Although it can realize automatic roll change, there are only four rolls when the rolls are placed on the roll changing device each time, and it also needs to be installed on the roll changing mechanism in advance, and multiple automatic roll changes cannot be realized.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Combing machine with automatic lap changing structure, such as Figure 1 and Figure 2 As shown, two device placement plates 1 are arranged vertically in pairs, and a rotary reel-changing disc 3 connected by a rotating shaft rod is arranged horizontally and fixedly connected to the device placement plate 1 through a bearing, and a motor shaft of a rotating motor 4 fixedly arranged on the device placement plate 1 is fixedly connected to the rotating shaft rod of the rotary reel-changing disc 3, so that the rotary reel-changing disc 3 can rotate relative to the device placement plate 1;

[0022] A reel changing tray placement cavity 11 is provided on the opposite end surface of the device placement plate 1, a vertically arranged material reel placement slot 2 is provided on the upper end surface of the device placement plate 1 and the opposite end surface thereof, and a material reel discharge port 12 communicating with the reel changing tray placement cavity 11 is provided at the lower end portion of the device placement plate 1;

[0023] like Figure 3 and Figure 4 As shown, the bottom end surface of the roll placement slot 2 that bears the weight of the roll is not located on the same plane as the rotating roll-changing disk 3. For example, the device placement plate 1 is arranged at the front end of the device, and the bottom end surface of the roll placement slot 2 is located behind the rotating roll-changing disk 3.

[0024] Four material roll grabbing blocks 31 and anti-overflow plates 33 are fixedly provided on the side end surface of the rotating roll changing disk 3, and an arc-shaped grabbing groove 311 is provided on the material roll grabbing block 31. The center of the grabbing groove 311 is located on a straight line with the center point of the material roll loading groove 32 provided on the side end surface of the rotating roll changing disk 3, so that the material roll can enter the material roll loading groove 32 due to gravity.

[0025] Before use, first sew the end of the shaft of the material roll A as Figure 1 As shown, the roll is placed in the roll placement slot 2, so that the shaft end of the roll A is inserted into the roll placement inner cavity 11 of the roll change disk, which is convenient for the roll grabbing block 31 on the side end surface of the rotating roll change disk 3 to grab;

[0026] Then, the rotary motor 4 is started, so that the rotary reel-changing disc 3 drives the material roll grabbing block 31 to rotate clockwise. When the material roll grabbing block 31 rotates to the material roll placement slot 2, since the material roll grabbing block 31 is provided with a grabbing slot 311, the shaft of the material roll A will be directly placed in the grabbing slot 311, and the rotary reel-changing disc 3 continues to rotate, which will drive the grabbed material roll A to rotate in the reel placement inner cavity 11. Figure 3 and Figure 4As shown, the right end surface of the roll placement slot 2 is connected to the roll-changing disk placement cavity 11, that is, the roll A at the bottom of the roll placement slot 2 can be moved into the roll-changing disk placement cavity 11 through this communication port;

[0027] When the grabbed roll A turns to the upper end of the rotary roll-changing disc 3, due to its own gravity, the roll A will fall from the grabbing slot 311 into the roll loading slot 32. During the falling process, the roll A may not be able to accurately enter the roll loading slot 32 due to the inertia of rotation. At this time, the anti-overflow plate 33 can prevent the roll A from overflowing the roll loading slot 32. When the roll A is placed in the roll loading slot 32 at the upper end of the rotary roll-changing disc 3, it is stationary. At this time, the shaft of the roll A can rotate in the roll loading slot 32. To realize the rotation of the material roll A, a linearly movable transmission motor is arranged in the device placement plate 1, that is, the transmission motor is arranged on the device placement plate 1 through a linear drive motor. When the material roll A rotates to the upper end surface of the rotating roll changing disk 3, the transmission motor is driven by the linear drive motor, so that the transmission motors on the two oppositely arranged device placement plates 1 move relatively, so that the motor shaft of the transmission motor abuts against the shaft end surfaces at both ends of the material roll A, that is, the material roll A is clamped. At this time, the transmission motor rotates, that is, the rotation of the material roll A is realized, and the feeding of the material roll A is realized;

[0028] When the roll needs to be changed, after the clamping of the material roll A is released, the rotating motor 4 is started again, so that the rotating roll changing disk 3 continues to rotate clockwise. When the material roll A rotates at the lower end of the plate 1, it will be directly discharged from the material roll discharge port 12 due to its own gravity.

[0029] Due to the gravity of the material roll A itself, after the previous material roll A is grabbed, a new material roll A will fall into the position of the previously grabbed material roll A, which is convenient for the continuous grabbing of the rotating reel changing disk 3.

[0030] The anti-overflow plate 33 fixed by the limiting rotating shaft can rotate counterclockwise, and the inclination angle with the side end face of the rotating reel changing disc 3 is between 60° and 75°, so when the rotating reel changing disc 3 drives the anti-overflow plate 33 to rotate to the bottom end face of the roll placement slot 2, it will be pressed by the roll A to rotate counterclockwise, but after passing the roll A, the anti-overflow plate 33 will return to the inclination angle with the rotating reel changing disc 3. This kind of rotation with automatic reset and limiting function can be realized by referring to patent number CN209638221U.

[0031] The anti-overflow plate 33 can also realize its reset function through a torsion spring, that is, it can be directly fixed on the side end surface of the rotating reel-changing disc 3 by the torsion spring to prevent the material roll A from overflowing.

[0032] This solution is mainly for realizing automatic roll changing, so the transmission motor that can move linearly is not shown in the drawings of the specification.

[0033] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
