[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0025] Reference Figure 1-6 A nonwoven fabric carding machine comprises a mounting plate 1 and an equipment body 2 mounted on the upper surface of the mounting plate 1. The equipment body 2 is a prior art, and its upper ends are respectively provided with a carding component and a winding component. A collecting hood 3 is provided in the middle of the equipment body 2, and a spiral conveying shaft 4 is rotatably provided inside the lower end of the collecting hood 3. A driving assembly is provided at the upper end of the spiral conveying shaft 4. An exhaust fan 9 is installed on the side of the equipment body 2 away from the driving assembly. A circulation cavity 10 is provided inside the middle body wall of the collecting hood 3. The exhaust fan 9 is connected to the circulation cavity 10 through a connecting pipe. A plurality of filter holes 11 are provided on the inner wall of the collecting hood 3 and corresponding to the circulation cavity 10. A compression box 5 is connected to the lower end of the collecting hood 3. An extrusion plate 7 is provided inside the compression box 5 through an electric cylinder 6. A hatch 8 is provided on the front side of the compression box 5 away from the electric cylinder 6, and a pressure relief assembly is provided on the upper side of the compression box 5 corresponding to the hatch 8. Example

[0026] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The pressure relief assembly includes a pressure relief plate 12 and a plurality of pressure relief holes 13. The pressure relief plate 12 is installed on the upper surface of the compression box 5 near the hatch 8. The pressure relief holes 13 are arranged on the plate body of the pressure relief plate 12. The arrangement of the pressure relief plate 12 and the pressure relief holes 13 facilitates the release and intake of gas inside the compression box 5 when the extrusion plate 7 moves, thereby preventing the gas inside the compression box 5 from being too low or too high and affecting the normal movement of the extrusion plate 7. The driving assembly includes a motor 14, two pulleys 15 and a belt 16. The motor 14 is installed on one side of the device body 2, and the two pulleys 15 are respectively installed At the upper end of the spiral conveying shaft 4 and the output end of the motor 14, a belt 16 connects two pulleys 15. The setting of the driving component is convenient for driving the spiral conveying shaft 4 to rotate, so as to facilitate the transportation of the fiber flocs filtered out from the filter hole 11 to the compression box 5; the equipment body 2 and the collecting cover 3 are equipped with matching protective shells 17 corresponding to the belt 16, and the pulley 15 and the belt 16 are located in the protective shell 17. The setting of the protective shell 17 is convenient for protecting the pulley 15 and the belt 16, that is, to avoid the phenomenon that the fiber flocs are entangled on the pulley 15 or the belt 16 and interfere with them.

[0028] The upper end of the collecting hood 3 is in an outward expansion state, and the spiral blades of the spiral conveying shaft 4 are in contact with the inner wall of the collecting hood 3. Since the upper end of the collecting hood 3 is in an outward expansion state, it is convenient for the fiber flocs that fall when the equipment main body 2 is combing the non-woven fabric to move to the spiral conveying shaft 4, so that the fiber flocs can be collected; a connecting seat 18 is provided on the upper side wall of the compression box 5 corresponding to the spiral conveying shaft 4, and the lower end of the spiral conveying shaft 4 is rotatably connected to the connecting seat 18. The setting of the connecting seat 18 improves the stability of the spiral conveying shaft 4 during rotation; a shielding cover 19 is fixed to the end of the compression box 5 away from the cabin door 8, and the electric cylinder 6 is located below the shielding cover 19. The setting of the shielding cover 19 is convenient for protecting the electric cylinder 6.

[0029] Principle and advantages of use: During the use of the utility model, the nonwoven fabric to be combed first passes through the roller and the needle rod on one side of the upper end of the equipment body 2, that is, combing is performed at this time, and the combed nonwoven fabric is rolled up on the reel on the other side of the upper end of the equipment body 2, thereby completing the combing process of the nonwoven fabric; and in the above process, the exhaust fan 9 is started, and the exhaust fan 9 sucks the air in the circulation cavity 10, that is, the gas in the collection cover 3 is sucked into the circulation cavity 10 and finally extracted through the exhaust fan 9, and in this process, air flow is formed inside the collection cover 3, that is, the gas above the collection cover 3 moves downward, thereby driving the air generated during combing. The fiber clumps move downward and are collected inside the collecting hood 3. As the screw conveying shaft 4 rotates, they are conveyed to the compression box 5. Under the action of the screw conveying shaft 4, the fiber clumps can be compressed to a certain extent first. When there are many fiber clumps in the compression box 5, the electric cylinder 6 is started, and the output end of the electric cylinder 6 pushes the extrusion plate 7 to move toward the hatch 8 in the compression box 5. That is, the fiber clumps inside the compression box 5 are gradually compressed into blocks by the extrusion plate 7. After the fiber clumps have been compressed for a certain period of time, the extrusion plate 7 can be reset by the electric cylinder 6. At this time, the personnel can open the hatch 8 to take out the fiber clumps that are roughly block-shaped after compression.

[0030] Therefore, with the mutual cooperation of the above-mentioned components, when this solution is used, the collected fiber flocs can be compressed, which not only allows the device to have a larger capacity for the fiber flocs, but also the fiber flocs that are roughly block-shaped after compression are easy for personnel to take, so that when personnel clean the collected fiber flocs, it is not easy for a large number of fiber flocs to be scattered to the outside. At the same time, since a spiral conveying shaft 4 is provided inside the collection cover 3, the spiral conveying shaft 4 not only improves the collection effect of the fiber flocs when it rotates, but also can clean the filter holes 11, thereby avoiding the phenomenon that the fiber flocs stick to the filter holes 11 and the suction effect of the exhaust fan 9 is hindered.

[0031] It should be further explained that the arrangement of the pressure relief plate 12 and the pressure relief hole 13 facilitates the release and intake of gas inside the compression box 5 when the extrusion plate 7 moves, thereby preventing the gas inside the compression box 5 from being too low or too high and affecting the normal movement of the extrusion plate 7; the arrangement of the driving assembly facilitates the rotation of the spiral conveying shaft 4, thereby facilitating the conveying of the fiber flocs filtered out from the filter hole 11 into the compression box 5; the arrangement of the protective shell 17 facilitates the protection of the pulley 15 and the belt 16, that is, preventing the fiber flocs from being entangled on the pulley 15 or the belt 16 and interfering with them; since the upper end of the collecting cover 3 is in an outward expansion state, it is convenient for the fiber flocs that fall when the equipment main body 2 is combing the non-woven fabric to move to the spiral conveying shaft 4, so that the fiber flocs can be collected; the arrangement of the connecting seat 18 improves the stability of the spiral conveying shaft 4 during rotation.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
