Description

Technical Field

[0001] This utility model relates to the field of wool textile technology, and in particular to a speed-adjustable device for a combing machine. Background Technology

[0002] A carding machine is an important textile machine that uses doubling, drafting, and carding processes. Primarily, carding straightens and aligns the fibers within the wool sliver, reducing fiber crossing or curling, thereby improving the efficiency of subsequent processing. However, during operation, the carding machine sometimes requires adjusting the movement speed of the wool sliver according to the actual working conditions.

[0003] In a typical pin combing machine, the movement of the brush tops is driven by a motor that rotates the rollers, which in turn carry the brush tops forward. Therefore, to adjust the movement speed of the brush tops on a pin combing machine, you only need to increase or decrease the motor speed, thereby adjusting the roller speed.

[0004] The wool strips entering the combing machine are originally wound on a winding reel, which rotates freely. When the rollers on the combing machine drive the wool strips forward, the tension transmitted through the wool strips causes the winding reel to rotate, thus automatically unwinding the yarn (it would be better to install a motor on each winding reel to drive its own rotation and unwind the yarn, but the cost is too high). Therefore, when the rollers drive the wool strips at a balanced speed, the rotation of the winding reel also maintains a roughly uniform speed.

[0005] Therefore, adjusting the speed of the bobbin by regulating the motor speed can cause several problems: First, when reducing the bobbin's movement speed, the motor speed can be instantly reduced, but the rotation of the winding reel does not automatically decrease instantly; instead, it maintains a relatively higher rotation speed for a period of time due to inertia. This causes the bobbin between the roller and the winding reel to become loose, making it prone to piling up, scattering, or even tangling. Second, when increasing the bobbin's movement speed, again, the motor speed can be instantly increased, but the rotation of the winding reel does not automatically increase instantly. This causes the tensile force between the roller and the winding reel to increase instantly, which can easily damage the bobbin or cause other adverse effects. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a speed-adjustable device for a combing machine, so as to solve some of the technical problems caused by the inability of the winding wheel to adjust its rotation speed in time when adjusting the speed of the bobbin in the prior art.

[0007] Based on the above objectives, this utility model provides a speed-adjustable device for a needle combing machine, including a wire feeding wheel rotatably connected to the base plate of the needle combing machine, wherein a plurality of blades are evenly arranged on the outer edge of one end side plate of the wire feeding wheel.

[0008] The adjustable device further includes:

[0009] A connector is provided on the base plate, and the side of the connector is provided with a groove. The side plate of the wire feeding wheel with blades is slidably connected in the groove.

[0010] The speed-increasing nozzle and speed-decelerating nozzle are installed in the chute. The speed-increasing nozzle and speed-decelerating nozzle increase or decrease the rotational speed of the wire feeding wheel by spraying air towards the blade.

[0011] Furthermore, the base plate of the combing machine is provided with end supports at both ends, wherein the end support at the front end is provided with a traction roller for pulling the hair strands.

[0012] Furthermore, the wire feeding reel is rotatably connected to the base plate via a mounting shaft, and the base plate is provided with several mounting positions for the wire feeding reel.

[0013] Furthermore, the upper end of the base plate is also provided with a strip routing plate, which is provided with several sets of strip guide components, and each set of strip guide components corresponds to an installation station.

[0014] Furthermore, the sliver guide assembly includes a steering guide roller vertically disposed on the upper end of the sliver routing plate and a limiting roller rotatably connected to the side wall of the sliver routing plate. The steering guide roller is rotatably connected to the sliver routing plate, and a pair of limiting rollers are provided, with the sliver passing through the middle of the two limiting rollers.

[0015] Furthermore, the base plate is also provided with a main air pipe, which is connected to the speed-up nozzle and speed-down nozzle in the connector, and the other end of the main air pipe is connected to an external air pump.

[0016] Furthermore, the connector is also provided with an acceleration branch channel and a deceleration branch channel, and the acceleration nozzle and the deceleration nozzle are respectively connected to the main air pipe through the acceleration branch channel and the deceleration branch channel.

[0017] Furthermore, each of the acceleration branch channel and the deceleration branch channel is equipped with a solenoid valve.

[0018] The beneficial effects of this utility model are as follows: 1. By setting multiple mounting stations on the base plate of the combing machine, the feed rollers are rotatably connected to the base plate via mounting shafts, allowing the feed rollers to be mounted horizontally on the base plate. Therefore, the feed rollers can rotate freely. Each mounting station is equipped with a set of bobbin guide components, enabling multiple feed rollers to feed yarn simultaneously and ultimately merge together via traction rollers.

[0019] 2. A connector is installed at the center of the base plate, and one end of the feed reel's side plate is slidably connected to a groove on the connector. Several blades are evenly distributed along the outer edge of this side plate, and acceleration and deceleration nozzles are installed within the groove. These nozzles eject high-speed airflow. The acceleration nozzles eject airflow in the same direction as the feed reel's rotation, while the deceleration nozzles eject airflow in the opposite direction. Therefore, their combined action can quickly increase or decrease the feed reel's speed, allowing it to adapt more quickly to the roller's traction speed and reducing adverse effects.

[0020] 3. The acceleration nozzle and deceleration nozzle are connected to the main air pipe through acceleration and deceleration tributaries, respectively, while the main air pipe is connected to an external air pump. Furthermore, each acceleration and deceleration tributary is equipped with a solenoid valve. By controlling the opening and closing of these solenoid valves, the operation of the acceleration and deceleration nozzles can be controlled, making control simple and convenient.

Detailed Implementation

[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] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 4 As shown, while the motor speed can be instantly reduced, the rotation of the winding reel does not automatically decrease instantly; instead, it maintains a relatively higher rotation speed for a period of time due to inertia. This causes the yarn sliver between the roller and the winding reel to become loose, leading to problems such as accumulation, tangling, or even knotting. Similarly, while the motor speed can be instantly increased, the rotation of the winding reel does not automatically increase instantly. This causes a sudden increase in the tension between the roller and the winding reel, which can easily damage the yarn sliver or cause other adverse effects. Therefore, to ensure that the rotation of the winding reel can be adjusted in a timely manner, this design includes a connector 108 on the base plate 101 of the combing machine, with a sliding groove 110 on its side.

[0032] Additionally, several blades 02 are evenly arranged on the outer edge of one end of the side plate of the wire feeding reel 01, and the side plate of the wire feeding reel 01 with the blades 02 is slidably connected to the groove 110. An acceleration nozzle 111 and a deceleration nozzle 112 are provided in the groove 110. The acceleration nozzle 111 and the deceleration nozzle 112 increase or decrease the rotational speed of the wire feeding reel 01 by spraying air towards the blades 02.

[0033] Preferably, the direction of the airflow ejected from the speed-up nozzle 111 is along the direction of rotation of the wire-feeding reel 01, while the direction of the airflow ejected from the speed-down nozzle 112 is against the direction of rotation of the wire-feeding reel 01.

[0034] Therefore, when adjusting the motor speed, the speed of the pay-off reel 01 can be adjusted synchronously by controlling the air jet from the speed-increasing nozzle 111 or the speed-decelerating nozzle 112. This allows the speed of the pay-off reel 01 to adapt to the roller traction speed more quickly, reducing the occurrence of adverse effects.

[0035] The first aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 5 As shown, the thread feeding wheel 01 is movably connected to the base plate 101 of the combing machine. The base plate 101 of the combing machine is also provided with end brackets 102 at both ends. The end bracket 102 at the front end is provided with a traction roller 104 for pulling the hairline thread.

[0036] Preferably, the wire feeding wheel 01 is rotatably connected to the base plate 101 via the mounting shaft 107, and the base plate 101 is provided with a plurality of mounting positions for the wire feeding wheel 01.

[0037] In addition, the sliver guide assembly includes a guide roller 105 vertically disposed on the upper end of the sliver feed plate 103 and a limiting roller 106 rotatably connected to the side wall of the sliver feed plate 103. The guide roller 105 is rotatably connected to the sliver feed plate 103, and a pair of limiting rollers 106 are provided, through which the sliver passes.

[0038] Multiple mounting stations are provided on the base plate 101 of the combing machine. The feed rollers 01 are rotatably connected to the base plate 101 via mounting shafts 107, allowing them to be mounted horizontally on the base plate 101. Therefore, the feed rollers 01 can rotate freely. Each mounting station is equipped with a set of yarn guide components, enabling multiple feed rollers 01 to feed yarn simultaneously and ultimately merge together via traction rollers 104.

[0039] The base plate 101 is also provided with a main air pipe 109, which is connected to the speed-up nozzle 111 and speed-down nozzle 112 in the connector 108, and the other end of the main air pipe 109 is connected to an external air pump.

[0040] The connector 108 is provided with an acceleration branch channel 113 and a deceleration branch channel 114. The acceleration nozzle 111 and the deceleration nozzle 112 are respectively connected to the main air pipe 109 through the acceleration branch channel 113 and the deceleration branch channel 114. Furthermore, a solenoid valve 115 is provided in each of the acceleration branch channel 113 and the deceleration branch channel 114.

[0041] Therefore, by controlling the opening and closing of the solenoid valve 115, it is possible to control whether the speed-up nozzle 111 and the speed-down nozzle 112 spray air, which is simple to control and easy to operate.

[0042] When the motor speed is increased, the solenoid valve 115 in the speed-up branch channel 113 is opened at the same time, so that the speed-up nozzle 111 sprays air. Since the air spray from the speed-up nozzle 111 is in the same direction as the rotation of the wire feeding wheel 01, it can blow the wire feeding wheel 01 to rotate faster, so that the rotation speed of the wire feeding wheel 01 can adapt to the roller traction speed more quickly.

[0043] When the motor speed is reduced, the solenoid valve 115 in the deceleration branch channel 114 is opened at the same time, so that the deceleration nozzle 112 sprays air. Since the air spray of the deceleration nozzle 112 is opposite to the rotation direction of the pay-off wheel 01, it can give the pay-off wheel 01 a resistance, so that its speed is reduced quickly to adapt to the roller traction speed and prevent the yarn from loosening and thus easily causing problems such as accumulation, scattering or even tangling.

[0044] In summary, this utility model provides multiple mounting stations on the base plate 101 of the combing machine. The feed rollers 01 are rotatably connected to the base plate 101 via mounting shafts 107, allowing them to be mounted horizontally on the base plate 101. Therefore, the feed rollers 01 can rotate freely. Each mounting station is equipped with a set of yarn guide components, enabling multiple feed rollers 01 to feed yarn simultaneously and ultimately merge together via traction rollers 104. A connector 108 is located at the center of the base plate 101, and one end of the feed roller 01's side plate is slidably connected to a groove 110 on the connector 108. Several blades 02 are evenly distributed on the outer edge of this side plate, and a speed-boosting nozzle 111 and a speed-reducing nozzle 112 are provided within the groove 110, allowing high-speed airflow to be emitted. The speed-boosting nozzle 111 ejects air in the same direction as the rotation of the pay-off reel 01, allowing the reel 01's rotation speed to adapt more quickly to the roller's traction speed and reducing adverse effects. The speed-reducing nozzle 112 ejects air in the opposite direction to the rotation of the pay-off reel 01. Therefore, the two nozzles work together to quickly increase or decrease the rotation speed of the pay-off reel 01. The speed-boosting nozzle 111 and speed-reducing nozzle 112 are connected to the main air pipe 109 via speed-boosting branch channels 113 and 114, respectively, and the main air pipe 109 is connected to an external air pump. Furthermore, each of the speed-boosting branch channels 113 and 114 is equipped with a solenoid valve 115. By controlling the opening and closing of the solenoid valves 115, the operation of the speed-boosting nozzle 111 and speed-reducing nozzle 112 can be controlled, making control simple and convenient.
