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 perfusing iodine tincture into a cotton swab tube and automated equipment thereof. Background Art

[0002] A multi-purpose self-flowing cotton swab is a cotton swab tube filled with iodine tincture disinfectant or alcohol disinfectant, with one end 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 typically made of polypropylene. The current production process utilizes a filling and sealing method, where liquid is first filled and then sealed with heat. During filling, a cone-shaped needle-shaped injection rod is used. External force is applied to push the needle into the cotton swab tube, simultaneously pushing the liquid into the tube. The other end of the cotton swab tube is not sealed, as this would create a confined space within the tube, preventing the liquid from being pushed in. Furthermore, because the filling process involves first filling the tube with liquid and then sealing it, when the heating rod heats the cotton swab tube to melt the polypropylene, the molten polypropylene rapidly cools when it encounters the liquid within the tube, significantly reducing the sealing effect and causing leakage in the cotton swab tube.

[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. The upper surface of the moving block is provided with a propulsion device, the upper surface of the propulsion device is provided with a sub-packaging plate, and one side of the positioning block is provided with a plurality of positioning sleeves, one end of the positioning sleeve is provided with a fine hole, the other end of the positioning sleeve is provided with a coarse hole, a trumpet sleeve is provided inside the coarse hole, an extended injection needle is provided on the inner side of the fine hole, and one end of the extended injection needle is provided with a medicine tube. The present invention facilitates the introduction of the cotton swab tube into the coarse hole through the trumpet sleeve by providing the trumpet sleeve, fixes the cotton swab tube to prevent the needle from being difficult to align, and effectively prevents leakage and waste by providing the extended injection needle to pass through the fine hole in the positioning sleeve to inject the cotton swab tube. The provision of a splint and a sliding top plate enables the lateral movement of the propulsion device to achieve smooth pushing of the medicine, thereby increasing stability and preventing loosening and leakage during the pushing process of the medicine.

[0005] Although the above technical solution can solve the problems of liquid leakage at the tube mouth during heat sealing and the thickening of the tube mouth sealing area 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.

[0042] Example 1

[0043] Reference Figure 1-12As shown, an automated device for perfusing iodine tincture with cotton swab tubes of the present invention comprises a feeding mechanism 1, a heat-melting mechanism 2, a material-dividing and transferring mechanism 3, a perfusion mechanism and a discharging mechanism 8 which are sequentially arranged on a frame 9. The feeding mechanism 1 comprises an incoming material body 10 which can accommodate a plurality of cotton swab tubes. A brush 15 arranged at the outlet of the incoming material body 10 is driven after deceleration by a first motor 14 installed outside the incoming material body 10, and is used to roll the cotton swab tube to a first card slot of a first station body 27 of the heat-melting mechanism 2. The incoming material body 10 is a box body with an inclined bottom and is fixed on a support plate 12 through a connecting member 11. The inclined setting allows the cotton swab tube to fall freely under the action of gravity. The support plate 12 is supported and fixed by an adjusting seat 13 located on the workbench of the frame 9, and can adjust the height of the incoming material body 10, that is, change the height relationship between the position of the outlet of the incoming material body 10 and the first station body 27; the heat-melting mechanism 2 comprises a first cam plate 23 and a first cam plate 24 which are relatively arranged. The first station body 27 is provided with a first guide assembly 26 suspended outside the first station body 27. The first station body 27 corresponds to the outlet position of the incoming material body 10. The guide assembly is connected to the second cam plate 29 and cooperates with the first slot on the first station body 27 to realize the loading and blanking operations of the cotton swab tube. The first cam follower 24 moves circumferentially along the first cam plate 23 and pushes its own heating core 2411 to extend out of the end of the heat-melted cotton swab tube and then reset. The second cam follower 25 moves circumferentially along the second cam plate 29 and pushes its own ejector pin 257 to eject the heat-melted cotton swab tube and then reset. The material distribution and transmission mechanism 3 includes a plurality of station fixtures 39 driven by a chain transmission assembly. The plurality of station fixtures 39 are gradually tilted and cooperate with the limit assembly to change the cotton swab tube falling from the first station body 27 from horizontal placement to vertical placement.The perfusion mechanism includes a first perfusion mechanism 4, a second perfusion mechanism 5 and an intermediate transmission mechanism located between the two. The first perfusion mechanism 4 includes a third cam plate 46 and a second rotatable station body 42. The second station body 42 is suspended with a second guide assembly 43. The second guide assembly 43 cooperates with the second card slot on the second station body 42 to receive the cotton swab tube arranged on the vertically arranged station fixture 39. The third cam plate 46 cooperates with the third cam follower 45. The third cam follower 45 moves circumferentially along the third cam plate 46 and pushes the first needle 456 carried by it to extend into the cotton swab tube to inject iodine tincture and then reset.

[0044] Example 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 into a cotton swab tube is provided. As for the specific structural design of the heat welding mechanism 2, the first station body 27 is located between the first cam follower 24 and the second cam follower 25. 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. Specifically, the The first workstation 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, and 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, pushing the first cam plate 23 to see whether it contacts the first cam follower 24, and then it 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 main body 27, causing the temperature at the slot to rise and the cotton swab tube to adhere. The first cam follower 24 includes several first cam reset parts arranged in a circle, each first cam reset part includes a first cam and a first elastic reset part and several 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 here. The first turntable 240 is provided with an annular first retaining ring and several circumferential first mounting positions. The first mounting position is fixed with a first slide rail, and a first slider is slidingly 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. The first sliding plate is provided with a first cam. 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 workstation body 27 along the direction of the first slide rail, which can 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 a blind hole and accommodates a plurality of heating cores 2411. The heating core 2411 drives 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 contacts 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 to the support plate 12 through a support rod 28. The support rod 28 is mounted in the rotating drum 21. The support rod 28 is fixed but the rotating drum 21 rotates. The first guide assembly 26 includes a plurality of first guide plates. The first guide plates are connected to the second cam plate 29 through a connecting rod and are arranged around the outside of the first workstation body 27, while leaving space for loading and unloading the cotton swab tube. The second cam follower 25 includes a plurality of second cam reset members arranged circumferentially, each second cam reset member includes a second cam 255 and a second elastic reset member and a plurality of ejector pins 257, the ejector pins 257 are 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 cannot 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, and a second slider 252 is slidingly 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, and 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, it can be seen that the second sliding plate 256 moves toward the first station body 27 along the direction of the second slide rail 251, thereby pushing the ejector pin 257 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 ejectors 257. The ejectors 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 contacts the second retaining ring, so that the ejector 257 is separated from the end of the cotton swab tube and retreats and resets 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 workstation body 27, thereby pushing the ejector 257 away from the end of the cotton swab tube and resetting it.

[0048] Example 3

[0049] Based on the technical solution of embodiment 3, an automated device for perfusing iodine tincture into a cotton swab tube is described. Figure 3 and Figure 9Each of the workstation fixtures 39 is mounted on an outer chain link 38, and several outer chain links 38 form a chain and are driven by a sprocket, wherein the chain and the active sprocket 33 and the driven sprocket 34 constitute a chain transmission assembly, and the overall direction of the chain transmission assembly is tilted. The two sprockets are mounted on the second support plate 32 and are driven after being decelerated by the third motor 31. 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 Arrangement, the third motor 31 is installed under 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 material is dropped from the first station body 27, the cotton swab tube is arranged horizontally on multiple station fixtures 39 arranged horizontally, and then the multiple station fixtures 39 change their position direction and the inclined setting gradually becomes a vertical setting.
