When the yarn is used, the chenille machine is used for spinning, and in order not to influence the production efficiency, the three modes are all independently operated and do not interfere with each other. The operation of the three modes is explained in detail below.

Firstly, a dust removal mode:

the servo transmission unit 11 is started to drive the gear 12 to rotate, and the gear 12 and the rack 4 are used for transmission, so that the rack 4 is fixed on the rack 2, and the gear 12 drives the first guide wheel assembly 8, the bottom plate 9, the movable box body 10, the centrifugal fan 14, the fan cabinet 13, the upper air outlet pipe 15 and the lower air outlet pipe 16 to do circular linear motion. Meanwhile, the centrifugal fan 14 sucks air from the outside, after the air is filtered by the filter screen, the air flows from the fan cabinet 13 to the upper air outlet pipe 15 and the lower air outlet pipe 16, and at the moment, the air speed in the pipe is increased due to the change of the sectional area of the air pipe. The high air speed at the air outlet of the upper air outlet pipe 15 can blow the flying flowers and hairiness in the upper spindle spinning area of the machine to the lower dust collection air duct 44 in the machine, and the high air speed at the air outlet of the lower air outlet pipe 16 can blow the flying flowers and hairiness in the ring spindle area of the lower spindle of the machine to the lower dust collection air duct 44 in the machine. The negative pressure fan 43 inside the fan box 7 causes a strong negative pressure inside the lower dust suction duct 44 connecting the fan box, so that the flying flowers and hairs suspended inside the machine are sucked into the duct and flow towards the rear fan box 7. The flying flowers and the hairiness finally reach a closed negative pressure cabin in the fan box, a roller blowing device 36 is arranged in the cabin, the flying flowers and the hairiness are adsorbed on a filter screen of the device, and a scraper motor arranged in the device drives a scraper to rotate to scrape the flying flowers and the hairiness from the filter screen. The vortex pump 38 has an air inlet and an air outlet, the two air inlets are respectively connected with one ends of a first hose 39 and a second hose 40, the other end of the first hose 39 is connected with the negative pressure chamber 37, the other end of the second hose 40 is connected with the cotton collection box connector 41, one end of a third hose 42 is connected with the cotton collection box connector 41, and the other end is connected with the negative pressure chamber 37. The vortex air pump 38, the first hose 39, the second hose 40, the third hose 42 and the cotton collecting box combining member 41 form a circulation cycle. The vortex air pump 38 forms a negative pressure higher than a negative pressure fan 43, the first hose 39 is connected with an air inlet and can be connected with a cotton collecting box combining piece 41, the third hose 42 sucks flying flowers and hairiness in a negative pressure cabin into the cotton collecting box combining piece 41, a filter screen is arranged in the cotton collecting box combining piece, the flying flowers and the hairiness can be adsorbed on the filter screen, meanwhile, the air outlet at the other end of the vortex air pump 38 can discharge sucked air into the negative pressure cabin 37 through the first hose 39, the flying flowers and the hairiness collected in the cotton collecting box combining piece 41 can be completely collected through a small door outside a cotton collecting box of a worker, and finally the purpose of dust removal of the machine is achieved.

II, a yarn detection mode:

the servo transmission unit 11 drives the gear 12 to rotate, and drives the first guide wheel assembly 8, the bottom plate 9 and the visual detection system (visual detection assembly) to do linear motion through transmission of the gear 12 and the rack 4. When the device moves to a designated position (the designated position can be detected by a contact switch and a corresponding controller, and the servo transmission unit is also controlled by an internal or external controller), the servo transmission unit 11 stops running, and the visual detection system photographs the yarn to obtain a related picture. The vision system uses its internal algorithm to distinguish whether the yarn meets the requirement, if it meets the algorithm requirement, the servo transmission unit 11 continues to run, and reaches the next detection position, if it does not meet the algorithm requirement, it gives NG signal to stop spinning at this position.

Thirdly, automatic doffing mode:

when the chenille machine obtains a doffing signal, doffing according to the following steps: s1, the servo transmission unit on the second guide wheel component 21 drives the gear wheel to rotate, the gear wheel and the rack 4 are used for transmission, and the dust removal detection mechanism (the itinerant dust removal and yarn detection device) drives the automatic doffing mechanism 6 to reach a first group of doffing positions, generally at the head or the tail of the machine. S2, after the chenille machine stops, the tail yarn is wound on the yarn gripper 29, and the yarn guide plate overturning device 31 overturns the yarn guide plate for a certain angle. And S3, the linear module 26 drives the lifting cylinder assembly 27 and the pipe grabbing assembly 28 to move from the original position to the direction of the full bobbin 30, and the operation is stopped after the bobbin grabbing position is reached. And S4, the pipe grabbing component 28 consists of an air cylinder and 5 groups of mechanical clamping jaws, and after the air cylinder is ventilated, the mechanical clamping jaws grab the full bobbin 30. And S5, the lifting cylinder assembly 27 moves upwards under the driving of the cylinder to pull the full bobbin 30 away from the spindle, and the lifting cylinder assembly 27 stops after rising to the highest position. And S6, the linear module 26 drives the lifting cylinder assembly 27 and the pipe grabbing assembly 28 to move to the original position and stop after returning to the original position. And S7, the air cylinder in the pipe grabbing assembly 28 is deflated, the mechanical clamping jaws loosen the full bobbin 30, and the full bobbin 30 rolls from the bobbin dropping guide plate 24 into the full yarn trolley 25. S8, when the linear module 26 moves to the original position, the servo transmission unit rotates to move the whole device to the second group of doffing positions, and after the device reaches the designated position, the steps S3-S8 are repeated.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
