A through groove is opened on the top wall of the cashmere carding machine body 1 corresponding to the position of the filter cover 2, and the mounting plate 3 is fixedly connected to the top wall of the cashmere carding machine body 1 by bolts. The motor 15 is a stepper motor or a servo motor.

[0024] In this embodiment, the provided mounting plate 3 can conveniently fix the filter cover 2 on the top wall of the cashmere carding machine body 1, the provided rotating shaft 4 is used to drive the needle puller 5 to rotate, the provided screen needle 6 is used to block the floating cashmere to prevent the cashmere from entering the filter mechanism 14, and there is no need to frequently clean the filter mechanism 14.

[0025] Example 2

[0026] like Figure 2 and Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0027] The transmission mechanism includes a No. 1 pulley 16 and a No. 2 pulley 17, and the No. 1 pulley 16 and the No. 2 pulley 17 are connected by a belt 18. The front end of the rotating shaft 4 passes through the front wall of the filter cover 2 through a bearing and is fixedly connected to the axial position of the No. 1 pulley 16. The fan shaft 12 passes through the front wall of the exhaust pipe 11 through a bearing and is fixedly connected to the axial position of the No. 2 pulley 17.

[0028] In this embodiment, the transmission mechanism is capable of driving the fan 13 to rotate during the rotation of the rotating shaft 4 without providing an additional power source, thereby making the device more closely connected. At the same time, the No. 1 pulley 16, the No. 2 pulley 17 and the belt 18 can also be configured as a combination of chain and sprockets. At the same time, in this embodiment, a protective cover can also be provided on the outside of the transmission mechanism to prevent accidents to the operator.

[0029] The filter mechanism 14 includes a filter frame 141 inserted into the air duct 10. A collecting groove 142 is provided on the side of the filter frame 141 away from the exhaust pipe 11. A top plate 143 is fixed to the top wall of the filter frame 141. The top plate 143 is fixed to the top wall of the air duct 10 by bolts.

[0030] In this embodiment, the filter mechanism 14 is configured to filter dust in the extracted air, and the collecting groove 142 is configured to prevent the filter frame 141 from scraping off dust accumulated on the side wall when the air is extracted, thereby preventing the dust from being scraped off into the air duct 10 .

[0031] Working principle: When the utility model is used, first turn on the switch of the motor 15, and the motor 15 drives the shaft 4 to rotate (with Figure 4 For example, the rotation direction of the rotating shaft 4 is clockwise), during the rotation of the rotating shaft 4, the fan shaft 12 is driven to rotate through the transmission mechanism, thereby driving the fan 13 to rotate, and the fan 13 draws the air in the cashmere combing machine body 1 into the filter cover 2. When the air passes through the sieve needles 6, the cashmere in the air is blocked by the sieve needles 6 on the right and bottom. Therefore, during the rotation of the rotating shaft 4, the needle pulling 5 can scrape the cashmere on the right sieve needles 6 into the cashmere combing machine body 1, and at the same time, the cashmere on the bottom sieve needles 6 will be brought to the left side of the inner cavity of the filter cover 2 by the needle pulling 5, and then fall onto the baffle 8 under the action of the left sieve needles 6. The electric push rod 9 is regularly controlled to extend, so that the cashmere on the baffle 8 falls back into the cashmere combing machine body 1. When the air that has taken out the cashmere passes through the air guide pipe 10, the dust it carries is filtered by the filtering mechanism 14, and the purified air is discharged through the exhaust pipe 11.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
