Description

Technical Field

[0001] The utility model belongs to the technical field of draw frames, and particularly relates to a coiler pressure mechanism for a drawing and roving machine. Background Technique

[0002] The function of the draw frame is to improve the internal structure of the sliver, thereby improving its long-section evenness, reducing the weight unevenness rate at the same time, straightening and parallelizing the fibers in the sliver, reducing the hooks, making the fineness meet the regulations, and mixing different types or qualities of raw materials evenly to reach the specified mixing ratio. Draw frames are divided into two categories: roller drafting draw frames and gill boxes according to the form of the drafting mechanism. There are various types of spinning draw frames, such as single-eye, two-eye, and four-eye. A draw frame that feeds multiple slivers and makes one sliver after combining and drafting is called a single-eye draw frame; a draw frame that outputs two slivers is called a two-eye draw frame, and so on. Each draw frame has an independent drive system. The draw frame consists of a feeding part, a drafting part, a forming part, and some automatic devices, etc. During the production process of the draw frame, a pressure mechanism is required to apply pressure to the sliver to make it into a larger sliver.

[0003] For example, a coiler pressure mechanism for a drawing and roving machine with a publication number of CN214527100U. By setting this device, it can control and fix the moving position of the coiling frame, improve the pressure effect on the cloth, and thus ensure the production quality of the cloth; it includes a bottom plate, two groups of slide rails, two groups of baffles, a coiling frame, a second motor, a second reducer, and a coiling roller. The two groups of slide rails are installed on the front side and the rear side of the top of the bottom plate, the two groups of baffles are installed on the left side and the right side of the top of the bottom plate, the output end of the second reducer passes through the first reducer and is connected to the front end of the coiling roller, and multiple groups of air-expansion blocks are arranged on the coiling roller; it also includes a first motor, a first reducer, a lead screw, a bearing seat, a threaded ring, a controller bracket, a controller, a scale, and a pointer. The controller is electrically connected to the second motor and the first motor. The scale is installed on the rear side of the top of the bottom plate, the pointer is installed at the rear end of the coiling frame, and the pointer corresponds to the scale in position;

[0004] This draw frame applies pressure to the cloth by pressing down the cloth strip. This structure is only used for coiling and cannot be applied to the drawing and roving operation. To solve the above problems, a coiler pressure mechanism for a drawing and roving machine is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a coiler pressure mechanism for a drawing and roving machine to solve the above problems, including:

At the bottom of the operating table 1, a second motor 11 is fixedly installed. A transmission belt is arranged between the second motor 11 and the gear disc 10. By driving the gear disc 10 to rotate through the second motor 11, since the two gear discs 10 are meshed with each other, the two gear discs 10 drive the two pressing discs 3 to rotate simultaneously. Put multiple thinner cotton strips into the inside of the closing block 2, and then put them between the two pressing discs 3. On the one hand, the cotton strips are conveyed by the rotation of the two pressing discs 3, and on the other hand, the cotton strips are extruded by the two pressing discs 3 to combine them into a larger cotton strip;

Both the first motor 7 and the second motor 11 are controlled by a PLC. A transmission belt is arranged between the output shaft of the first motor 7 and one side of the hinge block 6. When the first motor 7 works, the hinge block 6 rotates. A plurality of resistance plates 9 are fixedly installed on the right inner wall of the hinge block 6. During the rotation of the hinge block 6, the formed cotton strip contacts the resistance plates 9, and the cotton strip is driven by the resistance plates 9 to rotate along with the track of the hinge block 6. After the cotton strip is initially combined, put it into the inside of the hinge block 6. By the rotation of the hinge block 6, the initially coiled cotton strip rotates along with its track, so that the cotton strip is not easily dispersed after forming.

After the cotton strip is initially combined, put it into the inside of the hinge block 6. By the rotation of the hinge block 6, the initially coiled cotton strip rotates along with its track, so that the cotton strip is not easily dispersed after forming.
