[0045] The back-blowing control unit 409 includes a back-blowing cylinder 4091 which is installed at an equal angle at the bottom end of the horizontal plate 4061. The back-blowing cylinder 4091 is connected to the space inside the top cover 4062 located outside the fixed ring plate 4064. A piston 4092 is movably installed inside the back-blowing cylinder 4091. A third spring 4093 is fixedly installed at the bottom end of the piston 4092. The bottom end of the third spring 4093 is fixedly connected to the inner bottom wall of the back-blowing cylinder 4091.

After the textile work is finished, the fan body 4066 is powered off, and after the baffle 4068 moves back, the baffle ring 4071 moves upward to close the filter hole 4063, and at the same time drives the annular movable plate 4086 to move downward and contact the annular fixed plate 4084, so that the space between the bottom ring plate 4081 and the top ring plate 4082 is closed, and then the control piston 4092 moves upward to push the air to continuously recoil the filter hole 4063, and flush the dust and impurities into the space between the bottom ring plate 4081 and the top ring plate 4082, so as to facilitate the centralized treatment of the dust and impurities.

[0046] Working principle: When working, firstly, during installation, the bottom ring plate 4081 is sleeved on the outside of the top cover 4062, so that the bottom ring plate 4081 is installed on the top of the horizontal plate 4061, so that the end clamping piece 4089 on the horizontal rod 4088 is clamped and fixed with the top connecting piece 4077, and then the various inserting tubes 4051 at the bottom end of the bottom frame 401 are inserted into the interior of the various fixing tubes 301 at the top end of the connecting frame 2 to complete the installation;

[0047] When the device is in use, the fan body 4066 is turned on, thereby driving the air inside the fixed ring plate 4064 to move toward the side of the baffle 4068. Under the action of air pressure, the baffle 4068 is pushed to move downward. After the movement, the movable block 4052 is pushed downward by the first connecting rod 40613, thereby pushing the two clamping rods 4056 to move outward and clamp into the clamping groove 302 through the connecting rod 4057, thereby clamping and fixing the bottom frame 401 to improve the working stability;

[0048] When the first connecting rod 40613 moves downward, the second connecting rod 4072 drives the retaining ring 4071 to move downward, opens the connecting hole 4065, and connects the inner side of the fixed ring plate 4064 with the inner side of the top cover 4062. When the second connecting rod 4072 moves downward, the first rack 4073 drives the gear 4076 to rotate, and then the second rack 4075 pushes the longitudinal rod 4074 to move upward, thereby driving the annular movable plate 4086 to move upward. At this time, the outside air passes through the filter hole 4063 above the annular fixed plate 4084 and enters the inner side of the top cover 4062, and is finally discharged from the bottom groove 4067. When the air passes through the filter hole 4063, the dust impurities generated by textiles are filtered, and the dust impurities adhere to the vicinity of the filter hole 4063, which is convenient for handling the dust impurities.

[0049] When weaving is finished, the fan body 4066 is closed, and the baffle plate 4068 moves back under the elastic force of the second spring 40612, thereby pulling the first connecting rod 40613 to move upward, thereby driving the first rack 4073 to move upward, and driving the longitudinal rod 4074 to move downward through the gear 4076 and the second rack 4075, so that the baffle ring 4071 moves upward to close the connecting hole 4065 and the annular movable plate 4086 moves downward to contact the annular fixed plate 4084, and then the electromagnet 4095 is energized to generate a repulsive force on the magnetic block 4094, so that The piston 4092 moves upward, pushing the air outward, and blowing back the dust impurities adhering to the vicinity of the filter hole 4063 to between the bottom ring plate 4081 and the top ring plate 4082. When the dust needs to be processed, the end clamp 4089 is disengaged from the top connecting piece 4077, thereby removing the dust collection unit 408 and centrally processing the dust. When the baffle 4068 moves upward, it drives the movable block 4052 to move upward, so that the clamp rod 4056 moves back and disengages from the clamping slot 302, thereby facilitating the removal of the textile working component 4 for maintenance.
