Description

A loosening device Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to an opening device. Background Technology

[0002] Opening is a process of loosening compressed, entangled fiber raw materials and removing impurities. Existing opening equipment consists of a feed roller, a licker-in roller, a cylinder, and a doffer. The doffer is used to agglomerate the fibers on the cylinder surface into a fiber layer and transfer it to the next process. During the opening process, some residual fibers remain between the teeth on the doffer surface. If not cleaned in time, this will affect the fiber agglomeration effect. Currently, the practice is to manually clean the residual fibers on the doffer with a brush or other tools while the machine is stopped, and then restart the machine after cleaning. This method is time-consuming, labor-intensive, and reduces work efficiency. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] The purpose of this utility model is to provide an opening device, which aims to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

The doffer cleaning structure includes a cleaning roller with a plurality of brush bundles on its surface. Both ends of the cleaning roller are equipped with seated bearings. Each seated bearing is equipped with a U-shaped bracket, and the bottom of the seated bearing is connected to the inner bottom wall of the U-shaped bracket by a spring. The left side of the seated bearing is slidably connected to the inner left wall of the U-shaped bracket, and the right side of the seated bearing is slidably connected to the inner right wall of the U-shaped bracket. Both U-shaped brackets are fixedly mounted on the frame. A pressing component is provided above each U-shaped bracket for pressing the seated bearing downward and bringing the brush bundles into contact with the doffer.

[0005] Preferably, the cleaning roller is driven by a motor, and the rotation direction of the cleaning roller is opposite to the rotation direction of the doffer.

[0006] Preferably, the pressing assembly includes a cam, which is rotatably mounted on the frame. The cam is provided with a handle and an L-shaped locking rod. By rotating the cam with the handle, the protrusion of the cam can press down on the bearing seat and cause the bearing seat to move downward. The end of the L-shaped locking rod can be locked in a slot provided on the side wall of the U-shaped bracket to prevent the cam from rotating back.

[0007] Preferably, the pressing assembly includes a horizontal plate, which is fixedly installed at the top opening of the U-shaped bracket. The horizontal plate is provided with a set screw, which can be turned to move the bearing seat downward.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1

[0019] As shown in Figure 1, a preferred embodiment of this utility model provides an opening device, which includes a frame 1 on which rollers 2, cylinders 3, and doffers 4 are sequentially connected. Specifically, cylinder 3 is installed on one side of roller 2, and doffer 4 is installed on the side of cylinder 3 away from roller 2. The interaction between cylinder 3 and doffer 4 sorts and arranges the fibers. A cutting blade 5 is installed on the side of doffer 4 away from cylinder 3 to cut the fibers on doffer 4. Below the cutting blade 5 is a support roller 6, which is a smooth roller, used to assist in guiding the cut fibers into the next process.

[0020] The top of the doffer 4 is equipped with a doffer cleaning structure, as shown in Figure 2. The doffer cleaning structure includes a cleaning roller shaft 7, the surface of which is provided with several brush bundles. Both ends of the cleaning roller shaft 7 are respectively equipped with seated bearings 8. Each seated bearing 8 is equipped with a U-shaped bracket 9. The specific assembly structure is as follows: the seated bearing 8 is located inside the U-shaped bracket 9. The bottom of the seated bearing 8 is connected to the inner bottom wall of the U-shaped bracket 9 by a spring 10. The left side of the seated bearing 8 is slidably connected to the inner left wall of the U-shaped bracket 9, and the right side of the seated bearing 8 is slidably connected to the inner right wall of the U-shaped bracket 9. The above sliding connection adopts the method of groove and slider. Specifically, a vertical groove (not shown in the figure) is provided on the seated bearing 8, and a slider (not shown in the figure) is provided on the inner wall of the U-shaped bracket 9. The groove and the slider are slidably connected.

[0021] Two U-shaped brackets 9 are fixedly mounted on the frame 1, and a pressing assembly is provided above each U-shaped bracket 9. The pressing assembly includes a cam 11, which is rotatably mounted on the frame 1 via a bearing. The cam 11 is provided with a handle 12 and an L-shaped locking rod 13. In this embodiment, rotating the handle 12 counterclockwise causes the protrusion of the cam 11 to disengage from the top of the bearing 8, and the cleaning roller 7 is pushed upward by the spring 10, causing the brush bundle to disengage from the surface of the doffer 4. Rotating the handle 12 clockwise causes the protrusion of the cam 11 to interfere with the top of the bearing 8 and press down on the bearing 8, causing the bearing 8 to move downward and compressing the spring 10. At the same time, the brush bundle contacts the doffer 4. At this time, the end of the L-shaped locking rod 13 can be locked in the slot 14 provided on the side wall of the U-shaped bracket 9 to prevent the cam 11 from rotating back. In this state, rotating the cleaning roller 7 can brush off the lint on the surface of the doffer 4 through the brush bundle.

[0022] Furthermore, the cleaning roller 7 is driven by a motor, and the rotation direction of the cleaning roller 7 is opposite to that of the doffer 4, thereby improving the cleaning effect.

[0023] On the frame 1, specifically at the top of the cleaning roller 7, there is an openable cover 15. When the machine is stopped, the cover 15 can be opened to maintain and clean the cleaning roller 7.
