Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carding machines, in particular to an anti-breakage device for carding machines. Background Art
[0002] The carding machine is a spinning machine that combs the preliminarily processed spinning raw materials into single fibers, forming a thin layer of mesh fibers, and then assembles them into fiber strips. Due to different fiber types and process requirements, carding machines also have various structures, such as carding machines, wool carding machines, and linen carding machines. When the fiber material supply of the carding machine is interrupted, the operator controls the main doffer and the feeding mechanism to stop at the same time. In order to prevent the cylinder from being blocked, the main cylinder, the breast cylinder, and the licker-in roller are still rotating at high speed. When re-loading the feeding mechanism, the feeding mechanism is turned on first and then the main doffer. However, since the rotation speed of the first licker-in roller is much greater than that of the breast cylinder, there is no buffer when the long fibers are transferred between the two, which can easily cause damage to the long fibers and breakage of the net, making the subsequent fiber strips uneven in thickness and unable to be spun. Utility Model Content
[0003] Aiming at the problem that the long fibers lack buffer when being transferred between the double cylinders, the web is easily broken, resulting in uneven thickness of the produced fiber strips, the utility model provides a carding machine anti-breakage device.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A carding machine anti-breakage device comprises a machine body and a main cylinder, a breast cylinder, a first licker-in roller and a second licker-in roller installed on the machine body, wherein the main cylinder, the breast cylinder, the first licker-in roller and the second licker-in roller are all driven to rotate by a power mechanism; the first licker-in roller is located between the main cylinder and the breast cylinder, and the second licker-in roller is located on a side of the breast cylinder away from the first licker-in roller; a buffer doffer is provided, the buffer doffer is located between the breast cylinder and the first licker-in roller and is rotatably connected to the machine body, and the rotation direction of the buffer doffer is opposite to the rotation directions of the main cylinder and the breast cylinder.
[0006] Furthermore, the diameter of the main cylinder is greater than the diameter of the breast cylinder, and the linear speed of the main cylinder is the same as the linear speed of the breast cylinder.
[0007] Furthermore, the diameters of the first licker-in roller and the second licker-in roller are both smaller than the diameter of the breast cylinder.
[0008] Furthermore, the diameter of the buffer doffer is larger than the diameters of the first licker-in roller and the second licker-in roller, and smaller than the diameter of the breast cylinder.
[0009] Further, the rotation direction of the main cylinder is the same as the rotation direction of the breast cylinder, and the rotation direction of the first licker-in roller is the same as the rotation direction of the second licker-in roller.
[0010] Furthermore, the rotation direction of the main cylinder is opposite to the rotation directions of the first licker-in roller and the second licker-in roller.
[0011] Furthermore, the rotation direction of the buffer doffer is the same as the rotation direction of the first licker-in roller and the second licker-in roller.
[0012] The beneficial effects of the utility model are as follows: the utility model adds a buffer doffer between the main cylinder and the breast cylinder to buffer the long fibers transferred between the breast cylinder and the main cylinder, thereby reducing the damage to the long fibers, preventing the long fibers from breaking when the breast cylinder and the main cylinder rotate asynchronously, and avoiding the problem of uneven thickness of the produced fiber strips due to breaking. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 Shown is a schematic diagram of the structural principle of an implementation method of the utility model. DETAILED DESCRIPTION
[0014] The utility model discloses a carding machine anti-breakage device. An implementation mode of the utility model is specifically described below in conjunction with the accompanying drawings.
[0015] like Figure 1 As shown, a carding machine anti-breakage device includes a body 1 and a main cylinder 2, a breast cylinder 4, a first licker-in roller 3, a second licker-in roller 5, and a buffer doffer 6 installed on the body 1. Each part is driven to rotate by a power mechanism arranged on the body 1, and the power mechanism includes a motor, a synchronous pulley, and a synchronous belt. The breast cylinder 4 is located at the front side of the main cylinder 2. The diameter of the main cylinder 2 is larger than the diameter of the breast cylinder 4, and the main cylinder 2 and the breast cylinder 4 have the same rotation direction. The linear speed of the main cylinder 2 is the same as the linear speed of the breast cylinder 4, so that the main cylinder 2 and the breast cylinder 4 can rotate synchronously, reduce the uneven tension on the long fibers, and avoid the problem of long fiber breaking due to the different linear speeds of the two.
[0016] The first licker-in roller 3 is located between the breast cylinder 4 and the main cylinder 2, and the second licker-in roller 5 is located in front of the breast cylinder 4. The diameters of the first licker-in roller 3 and the second licker-in roller 5 are both smaller than the diameter of the breast cylinder 4. The rotation direction of the first licker-in roller 3 is the same as that of the second licker-in roller 5, and the rotation directions of the first licker-in roller 3 and the second licker-in roller 5 are opposite to that of the breast cylinder 4. The rotation speeds of the first licker-in roller 3 and the second licker-in roller 5 are much greater than the rotation speed of the breast cylinder 4.
[0017] The buffer doffer 6 is located between the breast cylinder 4 and the first licker-in roller 3, and the diameter of the buffer doffer 6 is larger than the diameters of the first licker-in roller 3 and the second licker-in roller 5, and smaller than the diameter of the breast cylinder 4. The rotation direction of the buffer doffer 6 is the same as that of the first licker-in roller 3 and the second licker-in roller 5.
[0018] The main cylinder 2, the breast cylinder 4, the first licker-in roller 3, the second licker-in roller 5 and the buffer doffer 6 are installed on the top of the machine body 1. The front side of the machine body 1 is provided with a feeding mechanism, and the rear side of the machine body 1 is provided with a main doffer, which is used to collect the fiber strips after being combed by the breast cylinder 4 and the main cylinder 2. The long fibers are fed into the machine body 1 from the feeding mechanism, and then enter the breast cylinder 4 through the second licker-in roller 5. The breast cylinder 4 pre-combs the long fibers and transfers them to the breast cylinder 4 through the first licker-in roller 3. However, when transferring the long fibers, since the rotation speed of the first licker-in roller 3 is greater than that of the breast cylinder 4, the long fibers are not buffered when they are transferred between the breast cylinder 4 and the first licker-in roller 3, and the strong pulling force of the first licker-in roller 3 easily causes the pre-combed long fibers to break.
[0019] The utility model adds a buffer doffer 6 between the main cylinder 2 and the breast cylinder 4 to buffer the long fibers transferred between the breast cylinder 4 and the main cylinder 2, thereby reducing damage to the long fibers and preventing the network from breaking during transfer, thereby avoiding the problem of uneven thickness of fiber strips in subsequent production due to network breaking, thereby avoiding the problem that the uneven thickness of fiber strips cannot be used for spinning in subsequent production.
[0020] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
