[0002] Circular knitting machines are generally divided into two categories: single-sided series and double-sided series. The double-sided circular knitting machine has the upper and lower needle cylinders arranged perpendicular to each other, and can be operated according to the set program of the circular knitting machine to obtain the desired textiles.

[0003] In the production process of large circular knitting machines, due to the large size of the equipment and the large number of yarns, the requirements for dust removal in the entire production process are relatively high.

[0005] The above-mentioned existing double-sided circular knitting machine can realize the movement of yarn or the collection of dust and cotton wool on the machine through the combination of the blower, the No. 1 air duct, the No. 2 air duct and the dust collecting device, so as to meet the automatic dust removal needs in the production process of the double-sided circular knitting machine. However, the overall position of the No. 1 air duct and the No. 2 air duct is fixed, and there are certain blind angle defects in the adsorption and dust removal effect on each side of the double-sided circular knitting machine.

[0018] The present invention is provided with a high-efficiency dust removal device, that is, when the main wheel, the secondary wheel and the gear ring are meshed, the secondary wheel can realize self-rotation and revolution activities to cooperate with the connecting shaft connected to the lower end of the main wheel, and assist in realizing the rotation of the connecting disk. In this way, the dust box and the dust collection structure arranged at the bottom of the connecting disk can be rotated to remove dust. At the same time, the self-rotating secondary wheel will indirectly realize the linkage transmission of the swinging structure, so that the swinging structure can realize the reciprocating swing of the dust box and the dust collection structure. In this way, the swinging dust collection activity can be realized while rotating dust collection, so as to greatly enhance the dust removal efficiency and range. At the same time, in the subsequent cleaning of the collected cotton wool or dust, the scraping structure transmission can be realized under the rotation drive of the fan, so as to enhance the cleanliness of the inside of the dust box.

[0019] The setting of the rotating structure, that is, when the main wheel rotates and meshes with the fixed gear ring, the secondary wheel can rotate and revolve accordingly, so that the secondary wheel can not only cooperate with the connecting shaft to realize the rotation of the connecting disk, but also transmit the first transmission gear and the second transmission gear to assist in realizing the linkage drive of the swing structure, thereby satisfying the simultaneous performance of rotary dust removal and reciprocating swing dust removal activities, greatly enhancing the dust removal efficiency in the production process of the double-sided circular knitting machine.

[0020] The setting of the swing structure, that is, the turntable can rotate synchronously with the second transmission gear, and the slider movably installed inside the turntable will move with the circular rotation to transmit to the transmission rod, so that the transmission rod cooperates with the connecting block and the rotating shaft to realize the stable reciprocating swing of the dust box and enhance the dust collection range of the dust box.

[0021] The dust suction structure, that is, the fan installed inside the fan box, can rotate quickly to absorb external cotton wool or dust and collect it inside the dust box, and realize convenient filtering and blocking activities through the filter screen provided at the air outlet of the dust box.

[0022] The setting of the scraping structure, that is, when the fan rotates, the docking shaft set in the middle of one side can be driven to make the scraper installed on the outside of the docking shaft rotate in a circle, thereby assisting in scraping and cleaning the outside of the filter to avoid clogging of the filter. At the same time, the fixing plate can be pulled to achieve threaded docking between the locking shaft and the scraper frame. In this way, with the meshing effect of the racks and gears on both sides, the lower and upper end plug-in frames can be plugged and locked with the scraper frame, so that the transmission bar can be quickly combined with the scraper frame, so that while the scraper rotates in a circle for cleaning, it can be transmitted and coordinated with the vertical groove opened on the outside of the transmission bar to drive the scraper frame to move back and forth along the inside of the dust box, thereby achieving rapid scraping and cleaning of cotton wool or dust attached to the inside of the dust box, and enhancing the efficiency of subsequent cleaning and pouring out.

[0023] The setting of the opening and closing structure, that is, the active connection between the card shaft and the connecting piece, and the rotational connection between the connecting piece and the handle, allows the card shaft to be flexibly rotated and adjusted as a whole to conveniently engage with the stop block to lock or unlock. In this way, the opening and closing of the bottom plate can be flexibly realized when cleaning the dust inside the dust box. BRIEF DESCRIPTION OF THE DRAWINGS

In this way, the lower end plug-in frame 4534 and the lock shaft 4538 can be moved toward the circular hole and the threaded hole provided in the scraper frame 455 respectively. When the lower end plug-in frame 4534 moves, the rack 4533 provided at the upper end will be pulled down, so that the rack 4533 3 realizes the rotation of the meshing gear 4532 at the upper end, so that the gear 4532 can realize the reverse transmission of the rack 4533 connected to the other side, so that the rack 4533 on the other side can push up the plug-in frame 4534 connected to the top, so that the lower end and the upper plug-in frame 4534 can move simultaneously to engage with the circular hole opened inside the scraper frame 455. At the same time, the locking shaft 4538 will be threadedly connected with the threaded hole inside the scraper frame 455, thereby conveniently realizing the quick locking combination of the moving bar 4531 and the scraper frame 455, so that when the scraper bar 452 performs a circular rotation activity, it can be transmitted with the vertical groove opened on the outer side of the moving bar 4531 The scraper frame 455 is moved to realize the reciprocating lateral movement of the moving bar 4531, and when the moving bar 4531 and the scraper frame 455 are not connected, the moving bar 4531 will be guided along the two guide rods 454 on one side to realize the self-moving activity without driving the scraper frame 455. After the combination activity is completed, the moving bar 4531 will realize the reciprocating lateral movement of the scraper frame 455, so that the scraper frame 455 cooperates with the brush layer 456 provided on the outside to scrape and clean the inside of the dust box 4442, so as to ensure the rapid cleaning and pouring out of the collected cotton wool or dust, and avoid the cotton wool or dust from being attached to the inner wall of the dust box 4442 in large quantities, which will affect the subsequent dust collection effect.

[0053] When the lower end plug-in frame 4534 is moved downward for plugging, the compression spring 4535 arranged on the outside is compressed. In this way, when the threaded connection between the lock shaft 4538 and the scraper frame 455 is subsequently released, the lower end plug-in frame 4534 can be quickly pushed up and reset with the elastic force of the compression spring 4535, while the plug-in frame 4534 on the other side can again cooperate with the meshing transmission of the rack 4533 and the gear 4532 to realize the synchronous reset activity.
