Description

Technical Field

[0001] The invention relates to the technical field of improved design of cotton swab manufacturing equipment, in particular to an operation method for filling iodine tincture into a cotton swab tube and an automated device thereof. Background Art

[0002] The multi-purpose self-flowing cotton swab is a cotton swab tube filled with iodine tincture disinfectant or alcohol disinfectant, one end of which is sealed. When the sealed end is broken, the iodine tincture or alcohol in the cotton swab tube flows to the cotton swab at the other end under the action of gravity, thus forming a multi-purpose disinfectant cotton swab stained with iodine tincture or alcohol. This iodine tincture or alcohol cotton swab is simple, convenient and hygienic to use.

[0003] Cotton swab tubes are generally made of polypropylene. In the current production process, they are made by first filling with liquid and then hot-sealing. During filling, a cone-shaped needle-type injection rod is used. Under the action of external force, the needle is pushed into the cotton swab tube and the liquid is pushed into the cotton swab tube at the same time. At this time, the other end of the cotton swab tube is not sealed, because after the other end is sealed, a closed space will be formed in the cotton swab tube, and the filling liquid cannot be pushed in. In addition, since the filling steps are to fill the liquid first and then seal, when the heating rod heats the cotton swab tube to melt the polypropylene, the molten polypropylene encounters the liquid in the tube and quickly cools down, causing the sealing effect to be greatly reduced, and the cotton swab tube leaks.

[0004] In the prior art, the patent with announcement number CN215043897U discloses a self-flowing cotton swab filling and preparation device, including a bottom plate, a moving block and a positioning block, a propulsion device is arranged on the upper surface of the moving block, a sub-loading plate is arranged on the upper surface of the propulsion device, a plurality of positioning sleeves are arranged on one side of the positioning block, a fine hole is arranged on one end of the positioning sleeve, a coarse hole is arranged on the other end of the positioning sleeve, a trumpet sleeve is arranged inside the coarse hole, an extended injection needle is arranged on the side surface inside the fine hole, and a medicine tube is arranged on one end of the extended injection needle. The present invention facilitates the introduction of the cotton swab tube into the coarse hole through the trumpet sleeve by arranging the trumpet sleeve, fixes the cotton swab tube to prevent the needle from being difficult to align, and effectively prevents leakage and waste by arranging the extended injection needle to pass through the fine hole in the positioning sleeve to inject the cotton swab tube. By arranging the clamp and the sliding top plate, the lateral movement of the propulsion device can be realized to achieve stable pushing of the medicine, which increases the stability and prevents loosening and leakage during the pushing of the medicine.

[0005] Although the above technical solution can solve the problems of leakage at the tube mouth during heat sealing and the tube mouth sealing becoming thicker and affecting the appearance, it requires the additional use of hot melt adhesive, and the use of an injection valve and a feed pipe, and the overall structural design is relatively complicated.

[0044] Embodiment 2

[0045] Reference Figure 4-8 As shown, on the basis of the technical solution of embodiment 1, an automated device for perfusing iodine tincture with a cotton swab tube, for the specific structural design of the hot welding mechanism 2, the first station body 27 is located between the first cam follower 24 and the second cam follower 25, and the first station body 27, the first cam follower 24 and the second cam follower 25 rotate coaxially, that is, the first station body 27 is respectively connected to the first turntable 240 of the first cam follower 24 and the second turntable 250 of the second cam follower 25, and specifically, the The first station body 27, the first turntable 240 and the second turntable 250 are all fixed on the drum 21. The drum 21 is mounted on the outside of the support rod 28 and is driven after being decelerated by the second motor installed on the support plate 12. Specifically, the second motor is installed on the support plate 12 and decelerated by a reduction mechanism. The reduction mechanism is a belt transmission mechanism, which drives the driven wheel 20 to work through the belt on the driving wheel. The output shaft of the driven wheel 20 is connected to the drum 21 to transmit power. The design of the drum 21 ensures that the support rod 28 does not interfere with the support and fixation of the second cam plate 29.

[0046] The first cam plate 23 can move axially and cooperate with the first cam follower 24. Specifically, a horizontal cylinder 22 is provided on the support plate 12, and the telescopic shaft of the horizontal cylinder 22 is connected to the first cam plate 23, which pushes the first cam plate 23 to see whether it contacts the first cam follower 24, and then can move according to the running trajectory of the cam mechanism. That is, although the first cam plate 23 is also fixed on the support plate 12, the distance between it and the first cam follower 24 can be adjusted by the horizontal cylinder 22, so that the heating core 2411 is pushed out only when hot welding operation is required, so as to avoid the situation where the heating core 2411 is always extended to the slot of the first workstation body 27, causing the temperature at the slot to rise and the cotton swab tube to adhere. The first cam follower 24 includes a plurality of first cam reset members arranged in a circle, each of which includes a first cam and a first elastic reset member and a plurality of heating cores 2411; the first turntable 240 is covered with a heating mold 241, and the heating mold 241 is provided with a heating hole for the heating core 2411 to pass through. The heating function of the heating mold 241 is not described in detail here. The first turntable 240 is provided with an annular first retaining ring and a plurality of circumferential first mounting positions, and a first slide rail is fixed on the first mounting position, and a first slider is slidably provided on the first slide rail. The first slider is connected to the first sliding plate so that it moves parallel to the axial direction of the first turntable 240. A first cam is provided on the first sliding plate. When the first cam contacts the first cam plate 23 and rotates along its contour, referring to the operating principle of the cam mechanism, it can be seen that the first sliding plate moves toward the first station body 27 along the direction of the first slide rail, so as to push the heating core 2411 to contact the end of the cotton swab tube to complete the hot melt sealing operation. In addition, the first sliding plate is provided with blind holes and accommodates a plurality of heating cores 2411. The heating cores 2411 drive the first sliding plate to move linearly as the first cam moves circumferentially along the first cam plate 23. The first elastic reset component is fixed on the first sliding plate. The first elastic reset component is a first spring pin. The first pin shaft end of the first spring pin is fixed on the first sliding plate. The first spring sleeved outside the first pin shaft abuts against the first retaining ring. When the first cam disengages from the contour of the first cam plate 23, the elastic force of the first spring pushes the first sliding plate away from the first workstation body 27, thereby pushing the heating core 2411 away from the blocked end of the cotton swab tube and resetting it.

[0047] The second cam plate 29 is fixed on the frame 9 and cooperates with the second cam follower 25. Specifically, the middle of the second cam plate 29 is fixed on the support plate 12 through a support rod 28. The support rod 28 is sleeved in the drum 21. The support rod 28 is fixed but the drum 21 rotates. The first guide assembly 26 includes a plurality of first guide plates.

The second cam follower 25 includes a plurality of second cam reset members arranged circumferentially, each of which includes a second cam 255, a second elastic reset member and a plurality of ejector pins 257, the ejector pins 257 being used to eject the movable cotton swab tube to prevent the cotton swab tube from being connected to the first card slot when the hot melt machine closes the end and thus being unable to fall freely; the second turntable 250 is provided with an annular second retaining ring and a plurality of circumferential second mounting positions, a second slide rail 251 is fixed on the second mounting position, a second slider 252 is slidably provided on the second slide rail 251, the movement direction of the second slider 252 is parallel to the axial direction of the first turntable 240, the second slider 252 is connected to the second sliding plate 256, the second sliding plate 256 is provided with a second cam 255, when the second cam 255 contacts the second cam plate 29 and rotates along its contour, referring to the operating principle of the cam mechanism, the second sliding plate 256 moves toward the first station body 27 along the direction of the second slide rail 251, and the ejector pin 257 can be pushed to complete the ejection operation of the cotton swab tube. In addition, the second sliding plate 256 is provided with a blind hole and accommodates a plurality of ejector pins 257. The ejector pins 257 drive the second sliding plate 256 to move linearly as the second cam 255 moves circumferentially along the second cam plate 29. A second elastic reset member is fixed on the second sliding plate 256. The second elastic reset member is a second spring pin 253. The second pin shaft end of the second spring pin 253 is fixed on the second sliding plate 256. The second spring sleeved outside the second pin shaft abuts against the second retaining ring, so that the ejector pin 257 is separated from the end of the cotton swab tube and retreats to reset after the ejection action is completed. When the second cam 255 is separated from the contour of the second cam plate 29, the elastic force of the second spring pushes the second sliding plate 256 away from the first station body 27, thereby pushing the ejector pin 257 away from the end of the cotton swab tube and reset.

[0048] Embodiment 3

[0049] Based on the technical solution of Example 3, an automated device for perfusing iodine with a cotton swab tube is described.

The two sprockets are installed on the second support plate 32 and are driven after the third motor 31 is decelerated. The third support plate 35 is supported by a rod above the second support plate 32, and a plurality of limit plates 36 are fixed on the third support plate 35. The limit plates 36 are provided with limit rods 37 that cooperate with a plurality of inclined fixtures, and the limit rods 37 are semicircular. The third motor 31 is installed below the first support plate 30. The first support plate 30 is arranged on the workbench of the frame 9 and cooperates with the bottom of multiple inclined fixtures to support the cotton swab tube. After the cotton swab tube is dropped from the first station body 27, it is arranged horizontally on multiple station fixtures 39 arranged horizontally.
