Description

Technical Field

[0001] The utility model relates to the technical field of improvement design of cotton swab manufacturing equipment, in particular to an automatic device for filling iodophor into cotton swab tubes. Background Art

[0002] The multi-purpose self-flowing cotton swab is a cotton swab tube filled with iodophor disinfectant or alcohol disinfectant, with one end sealed. When the sealed end is broken, the iodophor 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 disinfection cotton swab stained with iodophor or alcohol. This kind of iodophor or alcohol cotton swab is simple, convenient and hygienic to use.

[0003] The cotton swab tube is generally made of polypropylene. In the current production process, it is made by a filling and sealing method of first filling the liquid and then heat-sealing and plugging. When filling, a conical needle-type injection rod is used. Under the action of external force, the needle tip is pushed into the cotton swab tube while the liquid is pushed into the cotton swab tube. At this time, the other end of the cotton swab tube is not plugged, because if it is plugged at the other end, it will cause the problem that a closed space is formed in the cotton swab tube and the filling liquid cannot be pushed in. In addition, since the filling step is to fill the liquid first and then plug, when the heating rod heats the cotton swab tube to melt the polypropylene, the melted polypropylene meets the liquid in the tube and cools rapidly, resulting in a significant reduction in the sealing and ironing effect, and there is a liquid leakage phenomenon in the cotton swab tube.

[0004] In the prior art, the patent with the publication 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 dispensing plate is arranged on the upper surface of the propulsion device, a plurality of positioning sleeves are arranged on one side surface of the positioning block, a fine hole is arranged at one end of the positioning sleeve, a thick hole is arranged at the other end of the positioning sleeve, a horn sleeve is arranged inside the thick hole, an extended injection needle is arranged on the circumferential side surface inside the fine hole, and a medicine tube is arranged at one end of the extended injection needle. The utility model facilitates the introduction of the cotton swab tube into the thick hole through the horn sleeve, fixes the cotton swab tube to prevent the needle tip from being difficult to align, injects the cotton swab tube through the fine hole in the positioning sleeve by setting the extended injection needle, which can effectively prevent liquid leakage and waste, and realizes the lateral movement of the propulsion device through the setting of the clamping plate and the sliding top plate to smoothly push the medicine, increasing the smoothness and preventing the medicine from loosening and leaking during the pushing process.

[0005] In the above technical solution, although problems such as liquid leakage at the tube orifice and the thickening of the sealed and ironed part of the tube orifice affecting the appearance during heat sealing and ironing can be solved, additional hot melt adhesive is required, and a filling valve and a feeding pipe are used in a supporting manner, and the overall structural design is relatively complex.

[0039] Embodiment 1

[0040] Refer to Figure 1-12As shown in the figure, an automated device for filling iodophor into cotton swab tubes of the present utility model includes a feeding mechanism 1, a hot melting and welding mechanism 2, a material distribution and transfer mechanism 3, a filling mechanism, and a discharging mechanism 8 that are sequentially arranged on a frame 9. The feeding mechanism 1 includes a feeding main body 10 that can accommodate a plurality of cotton swab tubes. A brush 15 arranged at the outlet of the feeding main body 10 is driven by a first motor 14 installed outside the feeding main body 10 after speed reduction, and is used to roll and push the cotton swab tubes onto the first clamping groove of the first station main body 27 of the hot melting and welding mechanism 2. The feeding main body 10 is a box body with an inclined bottom and is fixed on a support plate 12 through a connecting piece 11. The inclined setting enables the cotton swab tubes to freely fall under the action of gravity. The support plate 12 is supported and fixed by an adjusting seat 13 on the working table of the frame 9, and can adjust the height of the feeding main body 10, that is, change the height relationship between the position of the outlet of the feeding main body 10 and the first station main body 27; The hot melting and welding mechanism 2 includes a first cam plate 23 and a second cam plate 29 arranged oppositely and a first station main body 27 located between the two. The first station main body 27 rotates self and matches with the position of the brush 15. A first guiding component 26 is suspended outside the first station main body 27. The first station main body 27 corresponds to the outlet position of the feeding main body 10. The guiding component is connected to the second cam plate 29 and cooperates with the first clamping groove on the first station main body 27 to realize the feeding and discharging operations of the cotton swab tubes. The first cam follower 24 moves along the circumferential direction of the first cam plate 23 and pushes the self - contained heating core 2411 to extend out of the end of the hot - melted cotton swab tube and then reset. The second cam follower 25 moves along the circumferential direction of the second cam plate 29 and pushes the self - contained ejector pin 257 to eject the hot - melted cotton swab tube and then reset; The material distribution and transfer mechanism 3 includes a plurality of station jigs 39 driven by a chain drive assembly. The plurality of station jigs 39 are arranged in a progressive inclined manner and cooperate with a limiting component to change the horizontal placement of the cotton swab tubes dropped from the first station main body 27 to a vertical placement;The described perfusion mechanism includes a first perfusion mechanism 4, a second perfusion mechanism 5, and an intermediate transfer mechanism located between the two. The first perfusion mechanism 4 includes a third cam plate 46 and a rotatable second station main body 42. A second alignment component 43 is suspended outside the second station main body 42. The second alignment component 43 cooperates with a second card slot on the second station main body 42 to receive the cotton swab tubes arranged on the vertically arranged station fixture 39. The third cam plate 46 cooperates with a third cam follower 45. The third cam follower 45 moves circumferentially along the third cam plate 46 and pushes the self - contained first needle 456 into the cotton swab tube to inject iodophor and then reset.

[0041] Embodiment 2

[0042] Refer to Figure 4-8 As shown, on the basis of the technical solution of Embodiment 1, for the specific structural design of the hot melting and connecting mechanism 2, the first station main body 27 is located between the first cam follower 24 and the second cam follower 25. The first station main body 27, the first cam follower 24, and the second cam follower 25 rotate coaxially, that is, the first station main 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 first station main body 27, the first turntable 240, and the second turntable 250 are all fixed on the rotating cylinder 21. The rotating cylinder 21 is sleeved outside the support rod 28 and is driven by a second motor installed on the support plate 12 after speed reduction. Specifically, the second motor is installed on the support plate 12 and is decelerated by a speed reduction mechanism. The speed reduction mechanism is a belt drive mechanism. The belt on the driving wheel drives the driven wheel 20 to work. The output shaft of the driven wheel 20 is connected to the rotating cylinder 21 to transmit power. The design of the rotating cylinder 21 ensures that the support and fixation of the second cam plate 29 by the support rod 28 will not cause interference.

[0043] The first cam plate 23 is axially movable and cooperates with the first cam follower 24. Specifically, a horizontal cylinder 22 is provided on the support plate 12. The telescopic shaft of the horizontal cylinder 22 is connected to the first cam plate 23 to push whether the first cam plate 23 contacts the first cam follower 24. Furthermore, it can act according to the running track 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 only pushed out when hot melting operation is required, to avoid the situation that the heating core 2411 always extends out to the slot of the first station body 27, resulting in the temperature rise at the slot and the adhesion of the cotton swab tube. The first cam follower 24 includes a number of first cam reset parts arranged in a circle. Each first cam reset part includes a first cam, a first elastic reset part and a number of heating cores 2411; a heating die 241 is sleeved outside the first turntable 240. The heating die 241 is provided with heating holes for the heating cores 2411 to pass through. The heating function of the heating die 241 will not be elaborated here. The first turntable 240 is provided with an annular first retaining ring and a number of circumferential first mounting positions. First slide rails are fixed on the first mounting positions. First sliders are slidably arranged on the first slide rails. The first sliders are connected to the first sliding plate to move in the axial direction parallel to 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 known that the first sliding plate moves towards the first station body 27 along the direction of the first slide rail, and thus can push the heating core 2411 to contact the end of the cotton swab tube to complete the hot melting and plugging operation. In addition, blind holes are formed on the first sliding plate and a number of heating cores 2411 are accommodated therein. The heating cores 2411 drive the linear movement of the first sliding plate as the first cam moves circumferentially along the first cam plate 23. A first elastic reset part is fixed on the first sliding plate. The first elastic reset part is a first spring pin. The end of the first pin shaft 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 station body 27, and thus can push the heating core 2411 to disengage from the plugging end of the cotton swab tube and reset.

[0044] 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 the support rod 28. The support rod 28 is sleeved in the rotating cylinder 21. The support rod 28 is fixed and immovable while the rotating cylinder 21 rotates on its own. The first guiding component 26 includes a plurality of first guiding pieces. The first guiding pieces are connected to the second cam plate 29 through connecting rods and are arranged around the outside of the first station main body 27, while leaving spaces for the feeding and discharging of the cotton swab tubes. The second cam follower 25 includes a number of second cam resetting pieces arranged circumferentially. Each second cam resetting piece includes a second cam 255, a second elastic resetting piece, and a number of ejector pins 257. The ejector pins 257 are used to eject the moving cotton swab tube to prevent the cotton swab tube from being connected to the first card slot when the closed end of the cotton swab tube is heat-sealed by the hot melt machine, resulting in the inability to freely discharge the material. The second turntable 250 is provided with an annular second retaining ring and a number of circumferential second mounting positions. The second slide rail 251 is fixed on the second mounting position. The second slide block 252 is slidably arranged on the second slide rail 251. The moving direction of the second slide block 252 is parallel to the axial direction of the first turntable 240. The second slide block 252 is connected to the second sliding plate 256. The second cam 255 is arranged on the second sliding plate 256. 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 known that the second sliding plate 256 moves towards the first station main body 27 along the direction of the second slide rail 251, and thus can push the ejector pins 257 to complete the feeding operation of the cotton swab tube. In addition, blind holes are formed on the second sliding plate 256 and a number of ejector pins 257 are accommodated therein. The ejector pins 257 drive the linear movement of the second sliding plate 256 as the second cam 255 moves circumferentially along the second cam plate 29. The second elastic resetting piece is fixed on the second sliding plate 256. The second elastic resetting piece is the second spring pin 253. The second pin end of the second spring pin 253 is fixed on the second sliding plate 256. The second spring sleeved on the second pin abuts against the second retaining ring, so that after the ejector pins 257 complete the ejecting action, they are separated from the end of the cotton swab tube and then retract and reset. When the second cam 255 disengages 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 main body 27, and thus can push the ejector pins 257 away from the end of the cotton swab tube and reset.

[0045] Embodiment 3

[0046] Based on the technical solution of Embodiment 3, an automatic device for filling iodophor into cotton swab tubes, referring to Figure 3 and Figure 9, each of the station jigs 39 is installed on an outer link 38, and a plurality of outer links 38 form a chain and are driven by a sprocket. Among them, the chain, the driving sprocket 33 and the driven sprocket 34 constitute a chain drive assembly, and the overall direction of the chain drive assembly is arranged obliquely. Both sprockets are installed on the second support plate 32 and driven after decelerating by the third motor 31. The third support plate 35 is supported above the second support plate 32 by a rod. A plurality of limit plates 36 are fixed on the third support plate 35. Limit rods 37 that cooperate with a plurality of obliquely arranged tooling jigs are provided on the limit plates 36. The limit rods 37 are arranged in a semicircular shape. 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 bottoms of a plurality of obliquely arranged tooling jigs to support the cotton swab tubes. Since the cotton swab tubes are arranged horizontally on the horizontally arranged plurality of station jigs 39 after blanking on the first station body 27, then the plurality of station jigs 39 change their position directions to be obliquely arranged and gradually become vertically arranged. At this time, to prevent the cotton swab tubes from slipping, the outer contour of the first support plate extends to form a baffle, which plays a role in supporting the cotton swab tubes. The shape of the tooling jig is designed as a bent plate structure and symmetrically provided with accommodation positions.
