Description

Technical Field

[0001] This utility model relates to the field of leveling devices, specifically a self-leveling device for a carding machine used in color spinning. Background Technology

[0002] The self-leveling device of a carding machine for colored spinning is an important technical component in the textile industry. Especially in the production of colored yarns, ensuring the uniformity of fibers is crucial. The carding machine itself is a device that combs, sorts, and separates cotton fibers or other fiber materials. It can separate short fibers, impurities, and irregular fibers from the raw materials to obtain more uniform and cleaner fiber bundles.

[0003] In the prior art, patent publication number CN222744467U describes a self-adjusting leveling device for a carding machine used in color spinning. Through an adjustment mechanism, the controller adjusts the extension and retraction of an electric telescopic rod according to a set thickness value. When the electric telescopic rod extends, it drives the pressure roller below to move downward, thereby reducing the thickness of the cotton roll layer. When the electric telescopic rod retracts, it increases the thickness of the cotton roll layer, thereby controlling the thickness of the cotton roll layer entering the carding machine in real time.

[0004] The above-mentioned existing technical solutions have some defects. When the thickness of the cotton roll layer entering the carding machine is reduced and adjusted by the pressure roller, if the local area of ​​the cotton roll layer is too thick, the edges of the cotton roll layer on both sides will be squeezed and bulge outward during the pressing process of the pressure roller, resulting in uneven edges of the cotton roll layer, which affects the fiber combing effect of the subsequent carding process. Utility Model Content

[0005] The purpose of this invention is to provide a self-regulating leveling device for a carding machine used in yarn spinning, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A self-leveling device for a carding machine for yarn spinning includes a carding machine mechanism. One end of the carding machine mechanism is provided with a leveling worktable. A pressing component for pressing down and leveling the thickness of the cotton roll layer is provided on the upper side of one side of the leveling worktable. Below the pressing component is an edge leveling component for leveling the two sides of the cotton roll layer. Unwinding rollers are provided on the upper sides of one end of the leveling worktable.

[0008] Preferably, the pressing assembly includes a fixed bracket, with the bottom ends of both ends of the fixed bracket fixedly installed on the upper end of the leveling worktable. A hydraulic lifting rod is fixedly installed at the center of the upper end of the fixed bracket, and a first pressure roller group is fixedly installed at the lower end of the hydraulic lifting rod. A second pressure roller group is positioned opposite each other below the first pressure roller group, and the second pressure roller group is fitted inside one side of the leveling worktable.

[0009] Preferably, the edge smoothing component includes a bidirectional motor, with fixed plates fixedly installed at both ends of the bidirectional motor. A bracket plate is fixedly connected to one side of each of the two fixed plates. A first lead screw and a second lead screw are movably sleeved inside the two bracket plates, and one end of the first lead screw and the second lead screw are respectively drivenly connected to the output shafts at both ends of the bidirectional motor.

[0010] Preferably, bushings are rotatably sleeved on the outer side of the first lead screw and the second lead screw away from the fixed plate, and the lower ends of the two bushings are respectively fixedly connected to the first support frame and the second support frame. The lower ends of the first support frame and the second support frame are respectively bolted to the upper ends of the two sides of the leveling worktable.

[0011] Preferably, a second L-shaped rod and a first L-shaped rod are rotatably connected to the outer side of one end of the first lead screw and the second lead screw, respectively, and one end of the first lead screw and the second lead screw are located inside the upper part of the second L-shaped rod and the first L-shaped rod, respectively.

[0012] Preferably, a sliding rod is fixedly connected to the lower end of both the second L-shaped rod and the first L-shaped rod. The sliding rod is slidably connected inside the lower end of the first support frame and the second support frame. A sliding groove is provided inside the lower end of both the first support frame and the second support frame.

[0013] Preferably, a first side leveling plate and a second side leveling plate are fixedly installed on one end of the sliding rod, and the first side leveling plate and the second side leveling plate are located on both sides of the cotton roll layer.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes an edge leveling assembly. A first screw rotates clockwise, causing a first L-shaped rod to move to the left, while a second screw rotates counterclockwise, causing a second L-shaped rod to move to the right. This causes the first and second side leveling plates to move relative to each other. The first and second side leveling plates move to the edges of the cotton roll layer being pressed down by the pressure rollers, maintaining parallelism with the cotton roll edges. The edges of the cotton roll layer contact the leveling plates, causing the edges to bulge. The two leveling plates move inward to compress the edges, preventing the edges of the cotton roll layer from being compressed and bulging outward during the pressure roller process. This effectively prevents uneven edges of the cotton roll layer and reduces the impact on the fiber combing effect in subsequent carding processes. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a self-leveling device for a carding machine for color spinning includes a carding machine mechanism 1. A leveling worktable 2 is provided at one end of the carding machine mechanism 1. A pressing component 4 for pressing down and leveling the thickness of the cotton roll layer is provided at the upper end of one side of the leveling worktable 2. An edge leveling component 5 for leveling the two sides of the cotton roll layer is provided below the pressing component 4. Unwinding rollers 3 are provided at the upper part of both sides of one end of the leveling worktable 2.

[0024] In a specific embodiment, the cotton roll is released from the unwinding roller 3, conveyed along the leveling worktable 2, and sequentially processed by the pressing component 4 and the edge leveling component 5 to finally form a cotton layer with uniform thickness and neat edges, which then enters the carding machine mechanism 1 for subsequent processing.

[0025] like Figure 1 and Figure 2 As shown, as a technical optimization of this utility model, the pressing component 4 includes a fixed bracket 41. The bottom ends of the fixed bracket 41 are fixedly installed on the upper end of the leveling worktable 2. A hydraulic lifting rod 42 is fixedly installed at the center of the upper end of the fixed bracket 41. A first pressure roller group 43 is fixedly installed at the lower end of the hydraulic lifting rod 42. A second pressure roller group 44 is opposite to each other below the first pressure roller group 43. The second pressure roller group 44 is sleeved inside one side of the leveling worktable 2.

[0026] In a specific embodiment, the hydraulic lifting rod 42 maintains a preset height, and an initial gap is formed between the first pressure roller group 43 and the second pressure roller group 44. The hydraulic cylinder drives the hydraulic lifting rod 42 to move up and down, further driving the first pressure roller group 43 to apply downward pressure. The second pressure roller group 44 provides reverse support force, forming bidirectional compression of the cotton roll layer, avoiding cotton layer displacement or uneven thickness caused by a single pressure roller. The cotton layer thickness is uniform after being pressed down, and then it enters the edge leveling component 5.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, as a technical optimization of this utility model, the edge smoothing component 5 includes a bidirectional motor 51. Both ends of the bidirectional motor 51 are fixedly mounted with fixing plates 52. One side of each fixing plate 52 is fixedly connected to a support plate 53. A first lead screw 55 and a second lead screw 56 are movably sleeved inside the two support plates 53. One end of the first lead screw 55 and the second lead screw 56 are respectively connected to the output shafts at both ends of the bidirectional motor 51. The ends of the first lead screw 55 and the second lead screw 56 furthest from the fixing plates 52 are... The two bushings 54 are rotatably sleeved on each side. The lower ends of the two bushings 54 are fixedly connected to the first support frame 510 and the second support frame 511 respectively. The lower ends of the first support frame 510 and the second support frame 511 are respectively bolted to the upper ends of the two sides of the leveling worktable 2. The outer sides of one end of the first lead screw 55 and the second lead screw 56 are rotatably connected to the second L-shaped rod 58 and the first L-shaped rod 57 respectively. The ends of the first lead screw 55 and the second lead screw 56 are located inside the second L-shaped rod 58 and the first L-shaped rod 57 respectively.

[0028] Furthermore, a sliding rod 59 is fixedly connected to the lower end of both the second L-shaped rod 58 and the first L-shaped rod 57. The sliding rod 59 is slidably connected to the lower end of the first support frame 510 and the second support frame 511. A sliding groove 512 is provided in the lower end of both the first support frame 510 and the second support frame 511. A side leveling plate, a first side leveling plate 513 and a second side leveling plate 514 are fixedly installed on one end of the sliding rod 59. The first side leveling plate 513 and the second side leveling plate 514 are located on both sides of the cotton roll layer.

[0029] In a specific embodiment, the bidirectional motor 51 can rotate in both directions. The output shafts at both ends drive the first lead screw 55 and the second lead screw 56 respectively. When it is necessary to adjust the edge uniformity position, the bidirectional motor 51 is energized and operates. The first lead screw 55 rotates clockwise to drive the first L-shaped rod 57 to move to the left, and the second lead screw 56 rotates counterclockwise to drive the second L-shaped rod 58 to move to the right. When the first L-shaped rod 57 and the second L-shaped rod 58 move relative to each other, the sliding rod 59 moves horizontally synchronously in the sliding groove 512, thereby driving the first side uniform plate 513 and the second side uniform plate 514 to move relative to each other. When the first side uniform plate 513 and the second side uniform plate 514 move to the edges of the cotton roll layer pressed down by the pressure roller group, they maintain parallelism with the edges of the cotton roll. The edges of the cotton roll are in contact with the uniform plates. If the edges of the cotton roll bulge, the two uniform plates move inward to squeeze the edges.

[0030] In use, the cotton roll is first released from the unwinding roller 3 and conveyed along the leveling worktable 2. It then passes through the pressing assembly 4 and the edge leveling assembly 5. A hydraulic cylinder drives the hydraulic lifting rod 42 to move up and down, further driving the first pressure roller group 43 to apply downward pressure. The second pressure roller group 44 provides reverse support, forming a bidirectional compression of the cotton roll layer. This avoids cotton layer shifting or uneven thickness caused by a single pressure roller, resulting in a uniform cotton layer thickness after pressing. The cotton roll then enters the edge leveling assembly 5. When the edge leveling position needs adjustment, the bidirectional motor 51 is energized. The first lead screw 55 rotates clockwise, driving the first L-shaped rod 57 to move to the left. The second lead screw 56 rotates counterclockwise, driving the second L-shaped rod 58 to move to the right. As the first L-shaped rod 57 and the second L-shaped rod 58 move relative to each other, the sliding rod 59 further slides in the sliding groove 512. The inner synchronous horizontal movement drives the first side leveling plate 513 and the second side leveling plate 514 to move relative to each other. When the first side leveling plate 513 and the second side leveling plate 514 move to the two sides of the cotton roll layer pressed down by the pressure roller group, they maintain parallelism with the cotton roll edge. The two sides of the cotton roll edge contact the leveling plate. If the cotton roll edge protrudes, the two leveling plates move inward to squeeze the edge.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
