Description

Technical Field

[0001] The utility model relates to the technical field of sliver coilers for carding machines, and particularly discloses a sliver coiler for carding machines. Background Art

[0002] The carding machine operates by opening, combing, and removing impurities from cotton (fiber) rolls delivered from the previous process or from cotton (chemical fiber) layers supplied by a cotton hopper. During this process, all curled tufts are combed into essentially straight single fibers, and broken seeds, impurities, and short fibers left over from the blowroom process are removed. These fibers are then gathered into slivers of a specified size and stored in cans for use in the draw frame process.

[0003] The carding machine's sliver coiler (faucet) is the device that coils and forms the sliver and stores it in the sliver can. After a certain amount of drafting, the sliver from the carding machine's large press roller enters the coiler. It is first supported and guided by the front and rear guide rollers, then bundled and tightened through the bell mouth. It is then compacted and formed by the small press rollers before being pulled and guided by the sliver inclined tube inside the coiling disc. Due to centrifugal force and gravity, the sliver is ejected through the outlet at the bottom of the coiling tube and finally neatly coiled into the sliver can. The coiling disc and sliver can are eccentrically positioned, and the sliver can rotates on a turntable at a lower speed than the coiling disc.

[0004] In the existing technology, the sliver can simply relies on the friction between the sliver can and the turntable to ensure its stable rotation on the turntable. However, as the number of slivers in the sliver can increases, its centrifugal force increases, and it is easy to deviate on the turntable, resulting in uneven winding of the slivers in the sliver can, affecting the capacity of a single sliver can and affecting production efficiency. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a sliver coiler for a carding machine to solve the problem that the sliver can is easily offset on the turntable when relying solely on friction.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A carding machine coiler includes a bracket, a coiling disk rotatably mounted on the top surface of the bracket, a turntable rotatably mounted on the bottom surface of the bracket, the coiling disk and the turntable being eccentrically disposed, a motor mounted on the bracket, the motor connected to the turntable and the coiling disk via a transmission mechanism, a tray inserted on the turntable, a sliver can placed on the top surface of the tray, and a clamping mechanism mounted on the tray to mate with the can. The inserted tray with the clamping mechanism can clamp the can placed on the tray, thereby increasing the clamping force, ensuring the stability of the can on the turntable, preventing deviation, ensuring the single-time capacity of the can, and ensuring production efficiency.

[0008] Preferably, a plurality of insertion rods are fixedly mounted on the top surface of the turntable; the plurality of insertion rods are evenly arranged along the circumference; a plurality of bosses are fixedly mounted on the outer wall of the tray corresponding to the insertion rods; the bosses are provided with through holes; and the insertion rods are inserted into the through holes. This facilitates the placement of the tray on the turntable and the maintenance of the clamping mechanism on the tray.

[0009] Preferably, the clamping mechanism includes a spring disposed between the bottom surface of the tray and the top surface of the turntable; the outer diameter of the spring is smaller than the outer diameter of the sliver can; two hinged seats are fixedly disposed on the outer wall of the tray; the two hinged seats are symmetrically arranged; an L-shaped rod is hingedly connected to the hinged seat; the lower portion of the vertical rod of the L-shaped rod is hinged to the hinged seat; the upper portion of the vertical rod of the L-shaped rod is hingedly connected to the clamp; the horizontal rod of the L-shaped rod extends away from the tray and abuts the upper surface of the turntable. As the sliver in the sliver can increases, the weight of the sliver can increases, pressing down on the spring, which in turn drives the L-shaped rod to rotate about its hinged connection with the hinged seat, causing the clamp to gradually clamp the sliver can, thereby preventing the sliver can from shifting on the tray, ensuring the single-time capacity of the sliver can, and ensuring production efficiency.

[0010] Preferably, the outer side of the connection between the horizontal rod and the vertical rod of the L-shaped rod is provided with a rounded corner, and the outer edge of the turntable abuts against the rounded corner, so as to facilitate the rotation of the L-shaped rod around its hinge.

[0011] Preferably, the outer side of the clamp is hinged to the upper part of the vertical rod of the L-shaped rod, and the inner side of the clamp is provided with a curved surface. The provision of the curved surface can increase the contact area with the sliver can and increase the friction.

[0012] Preferably, the transmission mechanism includes a transmission shaft rotatably arranged on a bracket; a rotating shaft is arranged in the middle of the bottom surface of the turntable; the lower part of the transmission shaft is connected to the rotating shaft through a first synchronous belt assembly; the upper part of the transmission shaft is connected to the coiling disk through a second synchronous belt assembly; and the upper end of the transmission shaft is connected to the output shaft of the motor.

[0013] The beneficial effects of the utility model are:

[0014] 1. The tray is equipped with a clamping mechanism, which can clamp the sliver can placed on the tray, increase the clamping force, ensure the stability of the sliver can on the turntable, avoid the occurrence of deviation, ensure the single capacity of the sliver can, and ensure production efficiency.

[0015] 2. Reasonable setting of the clamping mechanism can press down the spring as the slivers in the sliver can increase and the weight of the sliver can increases, thereby driving the L-shaped rod to rotate around the hinge with the hinge seat, so that the clamp gradually clamps the sliver can, avoiding the deviation of the sliver can on the tray, ensuring the single capacity of the sliver can and ensuring production efficiency.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] like Figure 1-4 The figure shows a sliver coiler for a carding machine, comprising a bracket 1. A sliver coiler 2 is rotatably mounted on the top surface of the bracket 1. The outer wall of the sliver coiler 2 is connected to the upper portion of a drive shaft 9 via a second synchronous belt assembly. The upper end of the drive shaft 9 is connected to the output shaft of a motor 10. A turntable 3 is rotatably mounted on the bottom surface of the bracket 1. The coiler 2 and turntable 3 are eccentrically positioned. A rotating shaft 302 is mounted on the bottom surface of the turntable 3. The rotating shaft 302 is connected to the lower portion of the drive shaft 9 via a first synchronous belt assembly. The first and second synchronous belt assemblies have different transmission ratios, and the motor 10 drives the sliver coiler 2 at a higher speed than the turntable 3.

[0026] In the above configuration, six insertion rods 301 are fixedly mounted on the top surface of the turntable 3; these six insertion rods 301 are evenly spaced along the circumference. Six bosses 401 are fixedly mounted on the outer wall of the tray 4, corresponding to the insertion rods 301. These bosses 401 are provided with through-holes, into which the insertion rods 301 are inserted. This completes the installation of the tray 4 on the turntable 3. This facilitates the installation of the tray 4 on the turntable 3 and the maintenance of the clamping mechanism on the tray 4. A sliver can 5 is placed on the tray 4.

[0027] Among them, the clamping mechanism includes a spring 6 arranged between the bottom surface of the tray 4 and the top surface of the turntable 3, the lower end of the spring 6 is fixedly set on the turntable 3, and the upper end of the spring 6 is in contact with the bottom surface of the tray 4; the outer diameter of the spring 6 is smaller than the outer diameter of the sliver tube 5, which is convenient for placement at the bottom of the sliver tube 5 and is placed in the six insertion rods 301; two hinged seats 402 are fixedly set on the outer wall of the tray 4; the two hinged seats 402 are symmetrically arranged; an L-shaped rod 7 is hinged on the hinged seat 402; the lower part of the vertical rod of the L-shaped rod 7 is hinged on the hinged seat 402; the upper part of the vertical rod of the L-shaped rod 7 is hinged on the outer surface of the clamp 8; the cross bar of the L-shaped rod 7 extends in the direction away from the tray 4 and is in contact with the upper surface of the turntable 3.

[0028] To facilitate the rotation of the L-shaped rod 7 around its hinge, the outer side of the connection between the horizontal rod and the vertical rod of the L-shaped rod 7 is provided with a chamfered corner 701; the outer edge of the turntable 3 abuts the chamfered corner 701. In order to increase the contact area with the sliver can 5 and increase the friction, the inner side of the clamp 8 is provided with a curved surface.

[0029] During use, as the number of tampons in the sliver canister 5 increases, the weight of the sliver canister 5 increases and presses down the spring 6. Since the outer edge of the turntable 3 abuts the chamfer 701, the L-shaped rod 7 rotates around the hinge with the hinge seat 402, and the clamp 8 gradually clamps the sliver canister 5, avoiding the deviation of the sliver canister 5 on the tray 4, ensuring the single capacity of the sliver canister 5, and ensuring production efficiency.

[0030] In another alternative embodiment, the clamping mechanism comprises four electric push rods, the piston rod ends of the electric push rods are hinged to the clamp 8, and the tray 4 is provided with a support rod, and the cylinder of the electric push rod is fixed to the support rod. Compared with this embodiment, an additional drive mechanism is added, which increases energy consumption.

[0031] Although the present invention has been described in detail with reference to the accompanying drawings and in conjunction with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, persons of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any changes or substitutions that can be easily conceived by persons skilled in the art within the technical scope disclosed in the present invention shall be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
