[0030] The adjustment component includes two screw rods 10 distributed on the left and right and rotatably connected to the base 1. A synchronous pulley 11 is concentrically fixed to the lower side of the screw rods 10. A synchronous belt 12 is connected between the left and right synchronous pulleys 11. A slider 13 is threadedly connected to the middle of the two screw rods 10. The cotton roll slot 9 is fixedly connected to the slider 13. An adjustment component for rotating one of the screw rods 10 is installed on the upper side.

[0031] The pressing assembly includes pressing sprockets 14 distributed on the left and right, and a pressing chain 15 is transmission-connected between the pressing sprockets 14. A plurality of pressing parts are evenly installed on the upper side of the outer belt surface of the pressing chain 15. The pressing parts include an elastic rod 16 fixed to the pressing chain 15, and the movable end of the elastic rod 16 is connected to a pressing wheel 17 matched with the rotating roller 6. A linkage assembly for enabling the pressing chain 15 to operate is installed on the side of the pressing chain 15.

[0032] In the present invention, the conveying device 2 in the cotton swab production machine is a key component of the entire production line. It is responsible for accurately and sequentially conveying the semi-finished cotton swab with cotton wool stuck on one end to the inner side of the support groove 4 of the carrying mechanism. When the conveyor belt 3 is running, when the spur gear 7 of the rotating shaft 5 moves to the upper side of the rack 8, the spur gear 7 and the rack 8 are meshed with each other. As the conveyor belt 3 moves, the spur gear 7 is driven to rotate through the rack 8, thereby driving the rotating roller 6 to rotate, so that the cotton swab semi-finished product as a whole rotates when moving left and right, and cooperates with the cotton rolling slot 9 to realize the winding of the cotton swab head; at the same time, the shapes of the different cotton rolling slots 9 distributed up and down are different, and the adjustment component cooperates with the synchronous pulley 11 and the synchronous belt 12 to make the two screws 10 rotate at the same time, so that the upper and lower cotton rolling slots 9 can be switched according to needs; the linkage component can control the pressing sprocket 14 to drive the pressing sprocket 14 to move synchronously with the conveyor belt 3, and the pressing wheel 17 applies pressure to the cotton sliver to ensure that the cotton swab is tightly fitted with the rotating roller 6.

[0033] Through the cooperation of the conveyor belt 3, the bearing mechanism, the spur gear 7 and the rack 8, the semi-finished cotton swab can rotate rapidly while moving, thereby realizing the automatic winding of the cotton swab head, improving the production efficiency of the equipment, and improving the firmness of the cotton swab head and the overall production quality of the cotton swab. The adjustment component can adjust and switch different types of cotton rolling slots 9 up and down as needed, so that the cotton winding device can produce different types of cotton swab heads according to needs, increasing the flexibility and applicability of the equipment. The cooperation of the lead screw 10 distributed on the left and right and the synchronous pulley 11 and the synchronous belt 12 can improve the stability of the cotton rolling slot 9. The linkage component enables the synchronous movement of the pressing chain 15 and the conveyor belt 3, which can ensure that the cotton swab can be pressed to the inside of the support slot 4 when winding cotton, ensuring the continuity and stability of the cotton sliver during the winding process.

[0034] The adjustment assembly includes a disc 18, which is transmission-connected to one of the lead screws 10. A limit rod 19 is vertically fixed on the upper side of the disc 18. A sleeve 20 is slidably connected to the upper side of the limit rod 19. A knob 21 is fixed to the top of the sleeve 20. A clamping plate 22 is fixed to the lower side of the sleeve 20. A plurality of latch teeth 23 are evenly distributed circumferentially on the upper side of the clamping plate 22. A ring 24 fixedly connected to the base 1 is installed on the upper side of the clamping plate 22. Clamping grooves 25 matching the latch teeth 23 are evenly opened on the lower side of the ring 24. A tensioning spring 26 is fixed between the clamping plate 22 and the disc 18.

[0035] When the adjustment assembly is not in use, the latch teeth 23 and the latch grooves 25 are meshed with each other, and the screw rod 10 cannot be rotated at this time. When in use, the screw rod 10 can be driven to rotate through the sleeve 20 by simply pressing the knob 21 downward.

[0036] The cooperation between the latch tooth 23 and the latch slot 25 makes the adjustment component easy to operate and also enables the latch tooth 23 and the latch slot 25 to fix the screw rod 10 after the adjustment is completed, thereby preventing the screw rod 10 from rotating, improving the stability of the cotton roll slot 9, thereby further improving the production accuracy of the cotton swab and improving the overall quality of the cotton swab.

[0037] The linkage assembly includes a first transmission gear 27 that is transmission-connected to the conveyor belt 3, a second transmission gear 28 that is meshed with the first transmission gear 27 is rotatably installed on the side, a transmission sprocket 29 that is rotationally connected to the two bases 1 is rotatably installed on the rear side of the second transmission gear 28, and a transmission chain 30 is commonly transmission-connected between the two transmission sprockets 29, one of the transmission sprockets 29 is transmission-connected to the second transmission gear 28, and the other transmission sprocket 29 is transmission-connected to one of the pressing sprockets 14, and the linear velocity of the pressing chain 15 is equal to that of the conveyor belt 3.

[0038] The movement of the conveyor belt 3 is transmitted to the pressing chain 15 through structures such as gears, sprockets and transmission chains 30, so that the pressing component can automatically move synchronously according to the speed of the conveyor belt 3 through the physical structure, thereby reducing the power source of the equipment and improving the energy utilization efficiency.

[0039] Guide plates 31 matching the support groove 4 and the cotton roll slot 9 are symmetrically installed on the front and rear sides of the conveyor belt 3. The guide plates 31 are fixedly connected to the base 1. The left sides of the cotton roll slot 9 are provided with arc chamfers 32.

[0040] The guide plates 31 symmetrically distributed front and back can guide the cotton swab in the front and rear positions of the support groove 4 on the upper side of the conveyor belt 3 to prevent the cotton swab from being displaced or slipping during the transmission process. At the same time, the arc chamfer 32 opened on the left side of the cotton roll slot 9 facilitates guiding the cotton swab into the cotton roll slot 9, thereby improving the stability and accuracy of the bearing mechanism during the transmission process, avoiding equipment failure caused by deviation or tilt, and damage to the cotton swab.

[0041] An alignment mark 33 is fixed to the front side of the guide plate 31 located at the front side, and an alignment plate 34 matching the alignment mark 33 is fixed to the left side of the cotton rolling clamping plate 22 .

[0045] The rotating block 36 hinged up and down and the clamping block 37 that can jump up and down can prevent the spur gear 7 and the rack 8 from blocking when the rotating shaft 5 moves left and right, so that the spur gear 7 and the gear can be transmitted smoothly, thereby extending the service life of the equipment.

[0046] The pitch of screw rod 10 is 10mm

[0047] The setting of the pitch of the screw rod 10 to 10 mm allows the user to ensure that the adjustment component can accurately adjust the position of the cotton roll slot 9 while allowing the knob 21 to quickly switch between different cotton roll slots 9, thereby improving the convenience of using the device.
