Description

Technical Field

[0001] The utility model relates to the technical field of the improvement design of cotton swab manufacturing equipment, in particular to an automatic perfusion device for disinfectant liquid on a cotton swab tube. Background Technique

[0002] The multi-purpose self-flowing cotton swab is a cotton swab tube filled with iodophor disinfectant or alcohol disinfectant. One end of the cotton swab tube is 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, thereby forming a multi-purpose disinfected 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. At present, in the production process, the filling and sealing method of first filling the liquid and then heat-sealing and plugging is adopted. 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, because 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 effect and leakage of the cotton swab tube.

[0004] In the prior art, the patent with the publication number of CN215043897U discloses a self-flowing cotton swab filling and preparing device, including a bottom plate, a moving block and a positioning block. A pushing device is arranged on the upper surface of the moving block, a dispensing plate is arranged on the upper surface of the pushing 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, a lengthened injection needle is arranged on the circumferential side surface inside the fine hole, and a medicine tube is arranged at one end of the lengthened injection needle. The utility model facilitates guiding 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 lengthened injection needle, which can effectively prevent liquid leakage and waste, and realizes the lateral movement of the pushing 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 part at the tube orifice affecting the appearance during heat sealing can be solved, additional feeding valves and feeding pipes need to be used, and the overall structural design is relatively complex.

[0006] In order to solve one of the above problems, the present application provides an automatic perfusion device for disinfectant liquid on a cotton swab tube. Content of the Utility Model

[0029] Example 1

[0030] Refer to Figures 1-3 As shown, an automatic perfusion device for disinfectant liquid on a cotton swab tube of the present utility model includes a first perfusion mechanism 4 and a second perfusion mechanism 5 sequentially arranged on a frame, 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 body 42. A second guiding and aligning component 43 is suspended outside the second station body 42. The second guiding and aligning component 43 cooperates with a second card slot on the second station body 42 to receive vertically arranged cotton swab tubes. The second guiding and aligning component 43 plays a role in guiding and supporting the cotton swab tubes. 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 its own first needle 456 into the cotton swab tube to inject disinfectant liquid and then resets. The intermediate transfer mechanism includes a rotatable third station body 491. A third guiding and aligning component 492 is suspended outside the third station body 491. The third guiding and aligning component 492 cooperates with a third card slot on the third station body 491 to receive the cotton swab tubes that have completed the injection of disinfectant liquid on the second station body 42. The second perfusion mechanism 5 has the same structure as the first perfusion mechanism 4 and both are transmitted with rotational power by a synchronous belt transmission component 494. The second perfusion mechanism 5 receives the cotton swab tubes conveyed by the third station body 491 and injects silicone oil into the cotton swab tubes through its own second needle and then resets.

[0031] Example 2

[0032] Refer to Figures 1-3 As shown, on the basis of the technical solution of Example 1, for an automatic perfusion device for disinfectant liquid on a cotton swab tube, as Figure 3 shown, for the specific structural design of the first perfusion mechanism 4, the second station body 42 is connected to a third turntable 450 of the third cam follower 45. A first chassis 41 and a first top plate 44 are respectively suspended at the upper and lower ends of the third turntable 450. In addition, the third cam follower 45 includes a plurality of circumferentially arranged third cam reset components. Each third cam reset component includes a third cam 455, a third elastic reset component, and a plurality of first needles 456. The third turntable 450 is provided with an annular third retaining ring and a plurality of circumferential third mounting positions. A third slide rail 451 is fixed on the third mounting position. A third slider 452 is slidably arranged on the third slide rail 451. The third slider 452 is connected to a third sliding plate 454. A third cam 455 is arranged on the third sliding plate 454. When the third cam 455 contacts the third cam plate 46 and rotates along its contour, referring to the operating principle of the cam mechanism, it can be known that the third sliding plate 454 moves towards the second station body 42 along the direction of the third slide rail 451, and thus can push the first needle 456 into the bottom of the cotton swab tube to complete the disinfectant injection operation.

[0033] Further, a number of first needles 456 are installed on the third sliding plate 454. The lower part of the first needle 456 penetrates through the first top plate 44. The upper end of the first needle 456 is connected to the first elbow pipe 47. The first elbow pipe 47 is fixed outside the first pneumatic slip ring 48. The first pneumatic slip ring 48 is connected to a plurality of peristaltic pumps. The peristaltic pumps are installed on the frame to start the function of pumping liquid. A third elastic reset member is fixed on the third sliding plate 454. The third elastic reset member is a third spring pin 453. The end of the third pin shaft of the third spring pin 453 is fixed on the third sliding plate 454. The third spring sleeved on the third pin shaft abuts against the third retaining ring. When the third cam 455 disengages from the contour of the third cam plate 46, the elastic force of the third spring pushes the third sliding plate 454 away from the second-station main body 42, and thus the first needle 456 can be pushed to disengage from the cotton swab tube and reset.

[0034] Further, the second alignment assembly 43 includes a plurality of second alignment pieces. The second alignment pieces are fixed on the first chassis 41. The second alignment pieces are matched with the second card slots on the second-station main body 42 to realize the feeding of the cotton swab tube from the feeding and transfer mechanism 3 to the first perfusion mechanism 4 and the feeding to the third-station main body 491 of the intermediate transfer mechanism.

[0035] Embodiment 3

[0036] As Figures 1-3 shown, on the basis of the technical solution of Embodiment 2, for the specific structural design of the second perfusion mechanism 5 of an automatic perfusion device for applying disinfectant liquid to a cotton swab tube, it can also refer to Figure 3 , the second perfusion mechanism 5 includes a fourth cam plate and a rotatable fourth-station main body. A fourth alignment assembly is suspended outside the fourth-station main body. The fourth alignment assembly is matched with the fourth card slots on the fourth-station main body to receive the cotton swab tube conveyed by the third-station main body 491. The fourth cam plate is matched with a fourth cam follower. The fourth cam follower includes a number of fourth cam reset members arranged in a circumferential array. Each fourth cam reset member is provided with a fourth cam, a fourth elastic reset member and a number of second needles. The fourth cam moves along the circumferential direction of the fourth cam plate and pushes the second needles to extend into the cotton swab tube to inject silicone oil and then reset. The specific actions can also refer to the operating principle of the cam mechanism and the spring reset design.

[0037] Further, the main body of the fourth station is connected to the fourth turntable of the fourth cam follower. Second chassis and second top plate that can rotate synchronously are respectively suspended at the upper and lower ends of the fourth turntable. Further, the fourth turntable is provided with an annular fourth retaining ring and a number of circumferential fourth mounting positions. Fourth slide rails are fixed on the fourth mounting positions. Fourth sliders are slidably arranged on the fourth slide rails. The fourth sliders are connected to a fourth sliding plate. A fourth cam is arranged on the fourth sliding plate. A number of second needles are mounted on the fourth sliding plate. The lower parts of the second needles penetrate through the second top plate. The upper ends of the second needles are connected to second bent pipes. The second bent pipes are fixed outside the second pneumatic slip ring. The second pneumatic slip ring is also connected to a plurality of peristaltic pumps. Further, a fourth elastic resetting member is fixed on the fourth sliding plate. The fourth elastic resetting member is a fourth spring pin. The end of the fourth pin shaft of the fourth spring pin is fixed on the fourth sliding plate. A fourth spring sleeved on the fourth pin shaft abuts against the fourth retaining ring. Further, the fourth guiding assembly includes a plurality of fourth guiding pieces, and the fourth guiding pieces are fixed on the second chassis.

[0038] Since the structures of the second perfusion mechanism 5 and the first perfusion mechanism 4 are the same, the difference is that the second needle is used instead of the first needle 456, and the liquid changes from disinfectant to silicone oil. The rotation power of both perfusion mechanisms is transmitted by a synchronous belt transmission assembly 494. The synchronous belt transmission assembly 494 is located under the workbench of the machine frame and is driven after decelerating by a fifth motor 495. The two synchronous wheels of the synchronous belt transmission assembly 494 are respectively connected to a first transmission shaft 40 and a second transmission shaft. The first transmission shaft 40 drives the main body of the second station 42 and the third turntable 450 to rotate. The second transmission shaft drives the main body of the fourth station and the fourth turntable of the fourth cam follower to rotate. The components and assembly of the second perfusion mechanism 5 refer to those of the first perfusion mechanism 4 and can correspond one by one, which will not be elaborated here.

[0039] In addition, the main body of the third station 491 of the intermediate transmission mechanism is driven after decelerating by a fourth motor 490. A third guiding assembly 492 is arranged on a support frame 493. The third guiding assembly 492 includes a plurality of third guiding pieces. The third guiding pieces cooperate with third clamping grooves on the main body of the third station 491 to realize the rotary transportation of the cotton swab tubes from the first perfusion mechanism 4 to the second perfusion mechanism 5. Finally, a control panel is also arranged on the machine frame to control the work of each motor, cylinder, peristaltic pump, etc., which will not be elaborated here.

[0040] In the device of the present utility model, the assembly and cooperation relationships of the various components involved, such as needles, peristaltic pumps, cylinders, motors and their control software, etc. are prior arts or materials. Those skilled in the art can directly purchase or customize them from the market according to the required product models and specifications.

[0041] All the electrical components mentioned in the text are electrically connected to the external main controller and 220V mains or industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.

[0042] As described above, only the preferred specific embodiments of the present invention are given, and common knowledge such as the specific structures and characteristics known to the public in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
