Description

A combing machine feed length adjustment device Technical Field

[0001] This utility model relates to the field of combed textile technology, and in particular to a combing machine feeding length adjustment device. Background Technology

[0002] As a core piece of equipment in textile production, the combing machine removes short fibers, neps, impurities, and tangled fibers from fibers through a physical combing process, improving fiber uniformity, parallelism, and straightness, ultimately forming a uniform combed yarn that provides high-quality raw materials for subsequent spinning processes. The precision of the combing machine's feed length adjustment directly affects the fiber combing effect, waste rate control, and yarn quality. In existing technologies, feed length control is mainly achieved through mechanical structure adjustments and process parameter settings. Specifically, this is generally done by changing the feed rollers of different diameters or adjusting the gear ratio of the transmission gears, thereby altering the amount of fiber output per roller rotation and directly affecting the feed length.

[0003] The adjustment accuracy of the transmission gear ratio is affected by factors such as gear meshing clearance and component wear, making it difficult to achieve precise control below ±0.3mm. Changing to a different diameter feed roller generally requires stopping the machine and making safety preparations before disconnecting the feed roller from the transmission gear (e.g., removing the ratchet lock nut on the FA261 model), removing the transmission chain or timing belt, and then installing the new roller. When installing a new roller, the roller diameter should be selected according to the fiber length. Generally, long fibers (≥38mm) are suitable for Φ28-32mm rollers, and short fibers (≤25mm) are suitable for Φ22-25mm rollers.

[0004] It can be seen that changing the feed rollers of different diameters is a relatively complicated process, which is troublesome to operate and will affect the original working condition of the combing machine, as well as the work efficiency and production rhythm of the workshop. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose a feeding length adjustment device for a combing machine, so as to solve the technical problem that it is troublesome and difficult to change feeding rollers of different diameters in the prior art, which affects the production rhythm and efficiency.

[0006] To achieve the above objectives, this utility model provides a combing machine feed length adjustment device, including a base roller with a diameter between 22-25 mm, and further comprising:

[0007] A power end plate is connected to one end of the base roller, and the power end plate is equipped with a power mechanism for driving the base roller to rotate;

[0008] A connecting end plate is connected to the other end of the base roller. The connecting end plate has a through hole. The other end of the base roller is located in the through hole. A retractable ball is provided in the through hole. The ball abuts against the base roller and is in rolling connection with it.

[0009] The sleeve roller has the same inner diameter as the base roller, and the diameter of the sleeve roller is between 28-32 mm.

[0010] Furthermore, the power mechanism is a drive motor, and the base roller is fixedly connected to the output shaft of the drive motor via a rotating shaft.

[0011] Furthermore, the rotating shaft is also provided with a slot, and the front end of the sleeve roller is provided with a buckle that cooperates with the slot.

[0012] Furthermore, the card slot is provided in several places, and the buckle is provided in several places accordingly, and the front end of the buckle is provided with an arc-shaped chamfer.

[0013] Furthermore, the through hole is also provided with an elastic telescopic component, which includes a movable component. Additionally, a movable groove is provided in the connecting end plate. The inner end of the movable component is slidably connected in the movable groove, and the ball is rotatably connected to the outer end of the movable component.

[0014] Furthermore, a spring is provided inside the movable groove, with the two ends of the spring connected to the inner end of the movable part and the bottom of the movable groove, respectively.

[0015] Furthermore, the elastic telescopic components are provided in several groups and arranged at equal angles within the through holes.

[0016] Furthermore, a sealing plate is provided on the outside of the through hole to seal the through hole. The sealing plate is slidably connected to the outside of the connecting end plate through a groove on the connecting end plate. The sealing plate is also provided with fixing bolts to fix the sealing plate to the connecting end plate.

[0017] The beneficial effects of this utility model are as follows: 1. A base roller with a diameter between -mm is designed for feeding short-fiber cotton fibers. A sleeve roller with a diameter between -mm is also provided for feeding long-fiber cotton fibers. Since the sleeve roller can be fitted onto the base roller, adjusting the feeding length only requires either fitting the sleeve roller onto the base roller or removing it from the base roller. This eliminates the need to disconnect the cotton feeding roller from the drive gear, remove the drive chain or timing belt, etc., making the adjustment simple and convenient and greatly reducing the impact on production rhythm and efficiency.

[0018] 2. One end of the base roller is located within a through hole on the connecting end plate. An elastic telescopic component and balls connected to the outer end of the telescopic component are installed within the through hole. The telescopic component can extend and retract with the balls. Therefore, when the sleeve roller is not installed, the balls can rest against the base roller and roll in contact with it. When the sleeve roller needs to be installed, the telescopic component allows the balls to retract, enabling the sleeve roller to pass smoothly through the through hole. After the sleeve roller is installed, the balls can rest against the sleeve roller and roll in contact with it. This ensures the stability of the rotation of either the base roller or the sleeve roller.

[0019] 3. The base roller is connected to the output shaft of the drive motor via a rotating shaft, and a slot is provided on the rotating shaft. The front end of the sleeve roller has a snap-fit ​​that mates with the slot. Therefore, it is not necessary to disconnect the connection between the cotton supply roller and the transmission component when installing or removing the sleeve roller; it is plug-and-play and easy to operate.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] As shown in Figures 1, 2, 3, and 4, the first aspect of this invention involves a complex process. Changing the feed roller to a different diameter typically requires stopping the machine and making safety preparations, disconnecting the feed roller from the drive gear, removing the drive chain or timing belt, and then installing the new roller. This process is cumbersome and can disrupt the combing machine's operation, impacting workshop efficiency and production rhythm. Therefore, this design incorporates a base roller 101 with a diameter between 22-25 mm. A power end plate 102 is installed at one end of the base roller 101, and a power mechanism is mounted on the power end plate 102 to drive the base roller 101 to rotate.

[0032] The key point is that it also involves the sleeve roller 115, whose inner diameter is the same as that of the base roller 101, and the diameter of the sleeve roller 115 is between 28-32mm. Therefore, the base roller 101 can be used for feeding short-fiber cotton fibers, while the sleeve roller 115 can be used for feeding long-fiber cotton fibers. The sleeve roller 115 can be fitted onto the base roller 101, so when it is necessary to adjust the feeding length, it is only necessary to fit the sleeve roller 115 onto the base roller 101, or remove the sleeve roller 115 from the base roller 101. There is no need to disconnect the cotton feeding roller from the drive gear, remove the drive chain or timing belt, etc. The adjustment operation is simple and convenient, greatly reducing the impact on production rhythm and efficiency.

[0033] Additionally, a connecting end plate 103 is provided at the other end of the base roller 101. The connecting end plate 103 has a through hole 107, and the other end of the base roller 101 is located inside the through hole 107. Furthermore, a sealing plate 113 is provided on the outside of the through hole 107 to seal the through hole 107. The sealing plate 113 is slidably connected to the outside of the connecting end plate 103 through a sliding groove 112 on the connecting end plate 103. The sealing plate 113 is also provided with fixing bolts 114 to fix the sealing plate 113 to the connecting end plate 103.

[0034] When installing or removing the sleeve roller 115, it can be done through the through hole 107. In this case, the sealing plate 113 needs to be opened, the fixing bolt 114 loosened, and the sealing plate 113 slid down to expose the through hole 107. After installation or removal, the sealing plate 113 is moved back to the through hole 107 and plugged, and then the fixing bolt 114 is tightened to fix the sealing plate 113 to the connecting end plate 103.

[0035] Preferably, the power mechanism is a drive motor 104, and the base roller 101 is fixedly connected to the output shaft of the drive motor 104 via a rotating shaft 105. Additionally, a slot 106 is provided on the rotating shaft 105, and a buckle 116 that mates with the slot 106 is provided at the front end of the sleeve roller 115. Several slots 106 are provided, and several buckles 116 are correspondingly provided, with a rounded chamfer at the front end of each buckle 116.

[0036] Therefore, when installing or removing the sleeve roller 115, it is not necessary to disconnect the connection between the cotton feeding roller and the transmission component. It is plug-and-play and easy to operate.

[0037] A second aspect of this invention, as shown in Figures 1, 3, 5, and 6, is to ensure the stability of the base roller 101 or the sleeve roller 115 during use. A retractable ball bearing 109 is provided within the through hole 107, the ball bearing 109 abutting against and rollingly connected to the base roller 101.

[0038] The ball bearing 109 is able to extend and retract through an elastic telescopic component. The through hole 107 is also provided with an elastic telescopic component, which includes a movable part 108. In addition, a movable groove 110 is provided in the connecting end plate 103. The inner end of the movable part 108 is slidably connected in the movable groove 110, and the ball bearing 109 is slidably connected to the outer end of the movable part 108.

[0039] A spring 111 is provided in the movable groove 110, and the two ends of the spring 111 are respectively connected to the inner end of the movable part 108 and the bottom of the movable groove 110.

[0040] Preferably, the elastic telescopic components are provided in several groups and arranged at equal angles in the through hole 107. Therefore, there are also several balls 109, and each movable part 108 has a ball 109 installed at its outer end.

[0041] The elastic telescopic component can extend and retract the ball bearing 109. Therefore, when the sleeve roller 115 is not installed, the ball bearing 109 can rest against the base roller 101 and roll with it. When the sleeve roller 115 needs to be installed, the telescopic component can retract the ball bearing 109 to allow the sleeve roller 115 to pass smoothly through the through hole 107. After the sleeve roller 115 is installed, the ball bearing 109 can rest against the sleeve roller 115 and roll with it. This ensures the stability of the rotation of the base roller 101 or the sleeve roller 115.

[0042] In summary, this invention utilizes a base roller 101 with a diameter between 22-25mm for feeding short-fiber cotton fibers. A sleeve roller 115 with a diameter between 28-32mm is also provided for feeding long-fiber cotton fibers. Since the sleeve roller 115 can be fitted onto the base roller 101, adjusting the feeding length is as simple as either fitting the sleeve roller 115 onto or removing it from the base roller 101. This eliminates the need to disconnect the cotton feeding roller from the drive gear, remove the drive chain or timing belt, etc., making adjustment simple and convenient and significantly reducing the impact on production rhythm and efficiency.

[0043] One end of the base roller 101 is located within a through hole 107 on the connecting end plate 103. An elastic telescopic component and a ball bearing 109 connected to the outer end of the elastic telescopic component are disposed within the through hole 107. The elastic telescopic component can extend and retract along with the ball bearing 109. Therefore, when the sleeve roller 115 is not installed, the ball bearing 109 can rest against the base roller 101 and roll in connection with it. When the sleeve roller 115 needs to be installed, the telescopic component can retract with the ball bearing 109, allowing the sleeve roller 115 to pass smoothly through the through hole 107. After the sleeve roller 115 is installed, the ball bearing 109 can rest against the sleeve roller 115 and roll in connection with it. This ensures the stability of the rotation of either the base roller 101 or the sleeve roller 115.

[0044] The base roller 101 is connected to the output shaft of the drive motor 104 via a rotating shaft 105. A slot 106 is also provided on the rotating shaft 105, and a snap-fit ​​116 that mates with the slot 106 is provided at the front end of the sleeve roller 115. Therefore, it is not necessary to disconnect the connection between the cotton supply roller and the transmission component when installing or removing the sleeve roller 115; it is plug-and-play and easy to operate.
