Description

Technical Field

[0001] This utility model relates to the field of cotton swab processing technology, and in particular to a cotton swab processing cutting device. Background Technology

[0002] Cotton swabs, also known as cleaning sticks, are small wooden or plastic sticks, slightly larger than a matchstick, wrapped with a small amount of sterilized cotton. They are mainly used in medical settings to apply medications and absorb pus and blood. There are many types of cotton swabs, including dust-free cleaning sticks, clean cotton swabs, medical cotton swabs, and instant cotton swabs.

[0003] The production process of cotton swabs includes two stages: swab processing and cotton processing. In the swab processing stage, the raw wood material needs to be processed into long strips before being put into the production line. During the production process, the swab also needs to be cut a second time according to the production needs, so that the swab is cut into a specified length, which requires the use of cutting equipment.

[0004] The existing cutting equipment does not have the function of position adjustment, and the semi-finished cutting bar is fixed on the conveyor belt. This means that different cutting equipment needs to be used for different cutting lengths during the production process, which reduces the processing equipment and makes it inconvenient to use.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 This is the first embodiment of the present invention, which provides a cotton swab processing cutting device, including a housing 1, a conveyor belt 2 inserted inside the housing 1, a cutting component 4 inside the housing 1, a fixing component 5 inside the housing 1, and a plurality of drive sprockets 3 inside the conveyor belt 2. The cutting component 4 includes a connecting shaft 404 inserted inside the housing 1, a blade 401 fixedly connected to one end of the connecting shaft 404 near the conveyor belt 2, a threaded sleeve 406 movably connected inside the connecting shaft 404 via a bearing, a threaded rod 407 threadedly connected inside the threaded sleeve 406, the end of the threaded rod 407 away from the blade 401 movably connected to the inner wall of the housing 1 via a bearing seat, a worm gear 413 fixedly connected to the outer surface of the threaded rod 407, a worm 411 meshing with the outer surface of the worm gear 413, and one end of the worm 411 movably connected to the inner wall of the housing 1 via a bearing seat.

[0033] Specifically, a stepper motor 408 is fixedly connected to the inner wall of the housing 1. The output end of the stepper motor 408 is fixedly connected to one end of the worm gear 411. A geared motor 402 is fixedly connected to the inner wall of the housing 1. A transmission gear 403 is fixedly connected to the output end of the geared motor 402. A toothed belt 409 is driven through the outer surface of the transmission gear 403. The side of the toothed belt 409 away from the transmission gear 403 is driven through the outer surface of the connecting shaft 404. A power component is provided on the lower surface of the conveyor belt 2. A threaded sleeve 406 is inserted inside the sleeve. Two limiting rods 410 are provided. The end of the limiting rod 410 away from the threaded sleeve 406 is fixedly connected to the inner wall of the housing 1. Two connecting blocks 412 are fixedly connected to the inner wall of the housing 1. The end of the connecting block 412 away from the blade 401 is fixedly connected to a limiting ring 405 for preventing the toothed belt 409 from dislodging. A rectangular groove for the movement of the skewer is provided inside the housing 1. Two mutually perpendicular inclined surfaces are provided inside the housing 1. Several dust suction holes are provided inside one of the inclined surfaces. A dust suction component connected to the dust suction holes is provided inside the housing 1.

[0034] Furthermore, the stepper motor 408 drives the worm gear 411 to rotate, and the worm gear 411 drives the threaded rod 407 to rotate via the worm wheel 413. This causes the threaded sleeve 406 to move the connecting shaft 404. During the movement of the connecting shaft 404, the toothed belt 409 moves within the toothed grooves on the outer surface of the connecting shaft 404, ultimately adjusting the position of the blade 401. The reduction motor 402 drives the connecting shaft 404 to rotate via the transmission gear 403 and the toothed belt 409. During the movement of the connecting shaft 404, the toothed belt 409 slides within the toothed grooves on the outer surface of the connecting shaft 404. The connecting block 412 and the limiting ring 405 limit the toothed belt 409, thereby preventing it from sliding and disengaging from the connecting shaft 404, thus driving... The blade 401 cuts the swab stick, and the resulting debris is absorbed by a dust-collecting component inside the housing 1. The cut swab stick is then conveyed out of the housing 1 through two mutually perpendicular inclined planes inside the housing 1, thus completing the cotton swab processing. The debris generated during cutting is absorbed by a dust-collecting hole and a dust-collecting component inside the housing 1. The small diameter of the dust-collecting hole allows the cut swab stick to slide down one inclined plane to another, thus rolling out of the housing 1. The power unit drives the conveyor belt 2 to move via the transmission sprocket 3. The connection relationship, working principle, and operating sequence between the power unit, the dust-collecting component, and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0035] Example 2

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The fixing component 5 includes two rotating gears 503 that are fixedly connected to the outer surface of the transmission sprocket 3 via connecting rods. The outer surface of the rotating gears 503 is meshed with a driven gear 502. The inside of the driven gear 502 is fixedly connected with a driving gear 501 via a connecting rod. The outer surface of the driving gear 501 is meshed with a synchronous belt 505. The outer surface of the synchronous belt 505 is fixedly connected with a plurality of connecting plates 506. The end of the connecting plate 506 away from the synchronous belt 505 is fixedly connected with a fixing block 507. The lower surface of the fixing block 507 is fixedly connected with a soft extrusion block 508.

[0037] Specifically, the inner wall of the chassis 1 is fixedly connected to an abutment block 504 by a connecting rod. The outer surface of the abutment block 504 abuts against the inner side of the synchronous belt 505. The upper surface of the conveyor belt 2 is provided with a groove for placing the skewer sticks. The soft extrusion block 508 cooperates with the groove.

[0038] Furthermore, during the movement of the conveyor belt 2, the transmission sprocket 3 drives the rotating gear 503 to rotate, and the rotating gear 503 drives the drive gear 501 to rotate through the driven gear 502. The drive gear 501 drives the synchronous belt 505 to move at the same speed as the conveyor belt 2, so that the soft extrusion block 508, which is fixedly connected to the outer surface of the synchronous belt 505 through the connecting plate 506 and the fixing block 507, extrudes the stick placed in the groove.

[0039] Working principle: Before cutting the cotton swab stick, the required cutting length is adjusted. A stepper motor 408 drives a worm gear 411 to rotate, which in turn drives a threaded rod 407 via a worm wheel 413. This causes the threaded sleeve 406 to move the connecting shaft 404. During the movement of the connecting shaft 404, a toothed belt 409 moves within the toothed grooves on the outer surface of the connecting shaft 404, ultimately adjusting the position of the blade 401. This allows for adjusting the cutting length of the cotton swab stick. The cotton swab stick is placed in a groove on the upper surface of the conveyor belt 2. The power unit drives the conveyor belt 2 via a transmission sprocket 3 to transport the cotton swab stick into the machine housing 1. During the movement of the conveyor belt 2, the transmission sprocket 3 drives a rotating gear 503 to rotate. The rotating gear 503, through a driven gear 502, drives a drive gear 501 to rotate. 1 drives the synchronous belt 505 to move at the same speed as the conveyor belt 2, so that the soft extrusion block 508, which is fixedly connected to the outer surface of the synchronous belt 505 through the connecting plate 506 and the fixing block 507, extrudes the swab placed in the groove to fix the swab. During the movement of the swab, the reduction motor 402 drives the connecting shaft 404 to rotate through the transmission gear 403 and the toothed belt 409, thereby driving the blade 401 to cut the swab. The debris generated by cutting is absorbed by the dust suction component set inside the machine box 1, and the cut swab is conveyed out of the machine box 1 through two mutually perpendicular inclined surfaces set inside the machine box 1, finally completing the processing and cutting of cotton swabs. It is convenient to adjust the cutting of swabs of different lengths, and the swab is squeezed by the fixing component 5 during the cutting process, thereby avoiding the swab shaking and the cutting being unqualified.
