Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carding, in particular to a carding device capable of preventing fiber damage. Background Technique
[0002] A carding machine is used for processing cotton fibers and chemical fibers and belongs to textile machinery. According to the spinning process flow, carding is an important process. The previous process of the carding machine is a blowing-carding unit, and the subsequent process is a drawing frame or a sliver lap machine.
[0003] The working principle of the carding machine is to convey the cotton raw materials supplied by the cotton box sent by the previous process, so that all the cotton laps in a curly block shape become single fibers that are basically straightened. And in this process, the broken seeds, impurities and short fibers left over from the blowing process are removed, and then a certain specification of cotton sliver is integrated and stored in the cotton cylinder for use in the drawing process.
[0004] However, in the process of conveying cotton, since a large mass of cotton raw materials are poured into the cotton box and cannot be effectively opened, it is easy to cause cotton blockage. The cotton raw materials are squeezed during the blockage process, which is likely to cause a certain degree of damage to the fibers of the raw materials. And during the conveying process, the humidity of the raw materials will also affect the quality of subsequent carding. Content of the Utility Model

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the detailed embodiments of the present invention will be described in detail below with reference to the drawings in the specification.
[0029] Embodiment 1
[0030] Reference Figures 1-5 , which is the first embodiment of the present utility model, provides a carding device capable of preventing fiber damage, including a machine case 1. One end of the inner wall of the machine case 1 is fixedly installed with a shunt plate 4, and the shunt plate 4 is used to divide the raw materials into two parts for transportation. Above the shunt plate 4, there are two first rotating wheels 5 rotatably installed on the two opposite inner cavity walls of the machine case 1. The bottom end of the shunt plate 4 is rotatably connected with a moving plate 17, and the moving plate 17 is used to preliminarily screen the raw materials. The two ends of the moving plate 17 are slidably connected with the inner wall of the machine case 1, and a mounting hole is penetrated through the moving plate 17. A screen mesh 8 is installed in the mounting hole in a matching manner. The bottom end of the shunt plate 4 is fixedly installed with a number of heating tubes 12 with the same specifications and linearly arrayed, and the heating tubes 12 are used to keep the inside of the machine case 1 dry and improve the quality of the raw materials in subsequent carding. One end of the machine case 1 is movably connected with an opening cotton roller 10, and the opening cotton roller 10 is used to loosen the raw materials for the second time.
[0031] Two mounting grooves are opened at the other end of the inner wall of the machine case 1. The two first rotating wheels 5 are mirror-symmetrically distributed in the inner cavity of the machine case 1, and the output ends of the two first rotating wheels 5 and the mounting grooves are on the same horizontal axis. One end of the mounting groove is fixedly installed with a first motor 11 whose output end is connected with the corresponding first rotating wheel 5. The first motor 11 is used to control the push plate 6 to rotate around the cross-section of the first rotating wheel 5. A plurality of push plates 6 are fixedly connected to the outer wall of the first rotating wheel 5, and the push plates 6 are used to push the raw materials for transportation to reduce the possibility of raw material blockage.
[0032] The heating tubes 12 are evenly distributed on the same axis at the bottom end of the shunt plate 4, and the two first rotating wheels 5 are mirror-symmetrically distributed on both sides of the top end of the shunt plate 4. A rectangular groove is opened at the bottom end of the shunt plate 4, and a third motor 18 is fixedly installed at the bottom end of the rectangular groove. The third motor 18 is used to drive the rotation of the cylindrical block 21. The output end of the third motor 18 is fixedly connected with a first main shaft 19. The bottom end of the first main shaft 19 is fixedly connected with a cylindrical block 21. The cylindrical block 21 is installed on one side of the bottom end of the first main shaft 19 and is not at the center of the circle. One end of the cylindrical block 21 is fixedly connected with a circular plate 22.
[0033] An elliptical hole 20 is formed at the bottom end of the moving plate 17 to facilitate the penetration of the cylindrical block 21. The inner wall of the elliptical hole 20 is rotatably connected to the outer wall of the cylindrical block 21. Sliders 23 are fixedly connected to both ends of the moving plate 17, enabling the moving plate 17 to move along the chute 24. The two opposite inner cavity walls of the chassis 1 are provided with chutes 24 to facilitate the sliding of the corresponding sliders 23. One end of the inner wall of the moving plate 17 is fixedly connected with a screen 8, which is used for the preliminary loosening of the raw materials. Two inclined plates 7 are fixedly connected to one end of the chassis 1, enabling the raw materials to smoothly enter one end of the moving plate 17. The inclined surface end of the inclined plate 7 is located between the shunt plate 4 and the moving plate 17. An inclined block 9 is fixedly connected to one end of the chassis 1, enabling the raw materials to enter the subsequent process.
[0034] During use, the raw materials are poured into the inner cavity of the chassis 1 from the feed inlet 2. The shunt plate 4 divides the raw materials into two parts. The first motor 11 is started, and the first motor 11 drives the first rotating wheel 5 to rotate. The first rotating wheel 5 drives the push plate 6 to rotate synchronously. During the rotation of the push plate 6, it contacts the raw materials and pushes the raw materials along the shunt plate 4 into the inclined plate 7 through the centrifugal force generated by the rotation. Since the top end of the shunt plate 4 is inclined, the push plate 6 will not miss the raw materials. The inclined plate 7 brings the raw materials to one end of the screen 8. The third motor 18 is started, and the third motor 18 drives the first main shaft 19 to rotate. The first main shaft 19 drives the cylindrical block 21 to rotate. Since the cylindrical block 21 penetrates the elliptical hole 20, the cylindrical block 21 pushes the moving plate 17. Originally, the cylindrical block 21 should drive the moving plate 17 to rotate, but due to the sliding connection between the two sides of the moving plate 17 and the inner wall of the chassis 1, the moving plate 17 cannot rotate synchronously and can only perform an axial linear movement along the chute 24. Also, because the cylindrical block 21 drives the elliptical hole 20, the moving plate 17 performs an axial linear reciprocating movement along the chute 24, and the raw materials are preliminarily loosened by the reciprocating movement of the screen 8.
[0035] Embodiment 2
[0036] Referring to Figure 1 、 Figure 4 and Figure 7 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that a fourth motor 14 is fixedly connected to one end of the outer wall of the chassis 1, which is used to control the rotation of the cotton opening roller 10. The output end of the fourth motor 14 is fixedly connected with a second main shaft 15, and the outer wall of the second main shaft 15 is fixedly connected with the inner wall of the cotton opening roller 10. Comb needles 25 are fixedly connected to the outer wall of the cotton opening roller 10, which are used to loosen the raw materials. A circular through-hole is formed through the inner cavity of the outer wall of the chassis 1, which is used to remove impurities in the raw materials.
[0037] The inner cavity of the circular through hole is adapted to be embedded with a filter screen 13 at the connection point with the inner cavity of the chassis 1. The filter screen 13 allows impurities in the raw material to pass through, but the raw material cannot pass through. A fan 16 is installed in the circular through hole. The fan 16 is used to absorb impurities in the raw material. A conveyor is fixedly connected to the bottom end of the inner cavity wall of the chassis 1, and a feed port 2 connected to the inner cavity of the chassis 1 is fixedly connected to the top end of the chassis 1, and a discharge port 3 is provided at the bottom end of the chassis 1 through the inner cavity of the chassis 1.
[0038] During use, the fourth motor 14 is started, the fourth motor 14 drives the second main shaft 15 to rotate, the second main shaft 15 drives the cotton opening roller 10 to rotate, the cotton opening roller 10 drives the combing needle 25 to rotate, the combing needle 25 combs and loosens the raw materials, so that the raw materials are not squeezed, the damage to the raw material fibers is reduced, and the quality of subsequent combing is improved. After opening, the impurities hidden inside the raw materials can be separated, and the fan 16 is started. Since the raw material itself has a certain weight and density, it can exist relatively stably in the chassis 1 and is not easily carried away by the airflow. After precise setting and control, it is ensured that while removing impurities and short fibers, it will not cause excessive attraction to the raw materials. The fan 16 sucks the impurities from the filter 13 and discharges them outside the chassis 1. The raw materials fall into the conveyor, and the conveyor transports the raw materials to the discharge port 3 through the conveyor belt for falling processing. The operation is now completed.
[0039] The remaining structures are the same as those of Example 1.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
