Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a swab packaging tube storage and feeding device. Background Art

[0002] As the main tool for sampling, such as collecting liquid microorganisms, DNA, virus bacteria, etc. from the human mouth, nose, throat, cervix, etc., swabs play an important role in the fields of forensic medicine, clinical medicine, environmental detection, etc.

[0003] The existing swab packaging mainly adopts two packaging methods: swab packaging bags and swab packaging tubes. Most of the common swab packaging tubes on the market are as Figure 12 shown. The swab packaging tube A mainly consists of a tube body A1 and a tube cap A2 that slides and closes on the head of the tube body A1. Among them, for the convenience of directly taking out the swab body A3 when the tube cap A2 is separated from the tube body A1, and also for the convenience of medical staff holding the swab body A3 during sampling, the swab body A3 is often fixed to the tube cap A2. However, since the swab body is a disposable sampling item and it needs to be stored in a sterile environment without contact with external air, in order to ensure the sealing between the tube cap and the tube body, a sealing strip will be pasted at the gap between the tube body A1 and the tube cap A2. This results in that when medical staff perform swab sampling, after taking the swab packaging tube from the swab packaging tube storage device, they need to tear off the sealing strip or cut the sealing strip with a tool, which obviously has the problem of being time-consuming and laborious.

[0004] Although there are also feeding devices for removing swab packaging in the existing technology, as recorded in the text of a sampling swab packaging peeling machine with the Chinese patent publication number CN218877833U. However, most of the swab packaging peeling machines recorded in the cited patent adopt the method of fixing and clamping and then using a linear cutting knife to cut the packaging. Obviously, this method is more suitable for removing bag-shaped swab packaging bags. If it is directly applied to cutting the sealing strip of a tubular swab packaging tube, it will cause the connection between the tube cap and the swab body to break. Then, whether it is possible to develop a swab packaging tube storage device that can not only continuously supply new swab packaging tubes, but also tear off or cut the sealing strip while supplying the swab packaging tubes, and does not damage the connection between the tube cap and the swab body, is a technical problem urgently to be solved in this field in recent years. Summary of the Invention

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a swab packaging tube storage and feeding device, which can not only continuously supply new swab packaging tubes, but also cut the sealing strip while supplying the swab packaging tubes, and does not damage the connection between the tube cap and the swab body.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A swab packaging tube storage and feeding device includes a cutting part and a feeding part for storing and supplying swab packaging tubes to the cutting part. Among them, the cutting part includes a motor, on the output shaft of the motor, a bow-shaped turntable and a driving gear are coaxially fixed. It also includes a supporting bottom wheel coaxially fixed with a driven gear meshing with the driving gear, and two swing rods distributed in an inverted V shape. On the lower swing shafts of the two swing rods, swing gears meshing with each other are coaxially fixed. On the upper cantilever ends of the two swing rods, clamping wheels are rotatably fitted. On at least one clamping wheel, a circular knife is coaxially fixed. The bow back and bowstring of the bow-shaped turntable are respectively abutted and cooperated with any swing rod, so that the two swing rods respectively form a clamping state and a separating state. During the clamping state, the supporting bottom wheel and the two clamping wheels jointly clamp the swab packaging tube and the circular knife rolls to cut off the sealing strip.

[0008] As a further solution of the present invention: the axes of the supporting bottom wheel and the clamping wheels are horizontally arranged, and the clamping wheels are symmetrically distributed on both sides above the supporting bottom wheel. When the swing rod is in the clamping state, the outer edges of the clamping wheels and the supporting bottom wheel jointly form a clamping area for clamping the swab packaging tube. In the normal state, the swing rod has a tendency to switch to the separating state. In the separating state, a feeding channel for the swab packaging tube to radially slide into is formed between the two clamping wheels in the clamping area.

[0009] As a further solution of the present invention: circular knives are coaxially fixed on both of the two clamping wheels.

[0010] As a further solution of the present invention: the cutting part can reciprocally slide along the axis of the clamped swab packaging tube. The storage and replenishment device further includes a top block that can move to the gap between the tube body and the tube cap of the clamped swab packaging tube. The cutting part clamps the tube body of the swab packaging tube. When the sealing strip at the gap between the tube body and the tube cap is cut off, and the cutting part clamps the tube body and slides away from the tube cap, the tube cap is blocked by the top block, so that the tube body and the tube cap are separated.

[0011] As a further solution of the present invention: the cutting part and the feeding part are both integrated on the housing. The cutting part clamps the swab packaging tube in the horizontal direction. A slide rail parallel to the axis of the clamped swab packaging tube is fixed on the housing. The cutting part is slidably fitted on the slide rail through a sliding seat. A bracket is also slidably fitted on the slide rail through a slider. When initially receiving the swab packaging tube, the tail of the tube body of the swab packaging tube is supported by the bracket and the supporting bottom wheel in the separated state of the swing rod respectively, and the head of the tube cap is supported. Taking the axis direction from the tube body to the tube cap as the positive direction and the axis direction from the tube cap to the tube body as the negative direction, the tail of the tube body is pushed by the bracket sliding forward, and the tube cap protrudes out of the housing. At this time, the top block and the circular knife are both located at the gap between the tube body and the tube cap, and the bracket and the cutting part respectively support the tail and the head of the tube body. The slider is driven by an electric cylinder to make a reciprocating sliding motion. A hook part is fixed on the slider through a pull rod. After the sealing strip at the gap between the tube body and the tube cap is cut off, when the electric cylinder drives the slider to slide reversely and the bracket is separated from the tail of the tube body, the hook part hooks and pulls the sliding seat to move reversely synchronously, so as to cause a separation action between the tube body and the tube cap. A reset elastic part for driving the sliding seat to slide forward and reset is also installed on the slide rail.

[0012] As a further solution of the present invention: a waste box for receiving the dropped tube body is installed on the housing.

[0013] As a further solution of the present invention: the feeding part includes a feeding hopper. The swab packaging tubes are horizontally stacked in the feeding hopper. The lower part of the feeding hopper has an opening with a length and a width respectively adapted to the length and the diameter of the swab packaging tube. A feeding power part for continuously supplying the swab packaging tubes to the clamping area is arranged at the opening.

[0014] As a further solution of the present invention: the feeding power part is a conveyor belt installed at the opening of the feeding hopper. The output end of the conveyor belt points to the feeding channel. When the conveyor belt is stationary, it generates a damping force to prevent the swab packaging tube from falling, and when the conveyor belt runs, it generates a driving force to drive the swab packaging tube to move towards the clamping area.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. After the feeding part supplies materials between the supporting bottom wheel and the two clamping wheels, the output shaft of the motor rotates and drives the driving gear and the bow-shaped turntable to rotate, thereby switching the swing rod to the clamping state. At this time, the supporting bottom wheel and the two clamping wheels jointly clamp the swab packaging tube. At the same time, under the meshing of the driving gear and the driven gear, the supporting bottom wheel also synchronously generates a rotating action, that is, during the period when the motor drives the swing rod to be in the clamping state, the supporting bottom wheel also drives the swab packaging tube to rotate synchronously, thereby realizing the rolling and cutting of the sealing strip at the gap between the tube body and the tube cap through the circular knife.

[0017] In the structural arrangement of the present application, only one power source, i.e., the motor, is required for the clamping of the swab packaging tube, the relative rotation of the circular knife and the outer periphery of the swab packaging tube, which significantly reduces the space occupied by the cutting part, and at the same time reduces the device cost and makes the program control simple and not prone to errors.

[0018] 2. In addition, by using the linkage method of driving the swing rod to rotate with the bow-shaped turntable, by changing the angles occupied by the arc section and the straight section of the bow-shaped turntable, the duration of the clamping and separating states can be changed; by changing the diameter of the bow-shaped turntable, the adjustment of the swing angle of the swing rod can be realized, which is convenient for the device to adapt to the debugging of the swing angle of the swing rod when fitting swab packaging tubes with different diameters. At the same time, the output shaft of the motor drives the support bottom wheel to rotate by the meshing drive of the driving gear and the driven gear. By controlling the gear ratio of the driving gear and the driven gear, when the output shaft of the motor rotates one circle, the support bottom wheel can rotate more than one circle, ensuring that during the period when the swing rod is in the clamping state, the support bottom wheel drives the swab packaging tube to rotate at least one circumference, so as to ensure that the sealing strips on the outer periphery of the swab packaging tube are all rolled and cut off.

[0019] 2. The axes of the clamping wheels and the support bottom wheel are horizontally arranged, and in the separated state, a feeding channel for the radial sliding of the swab packaging tube is formed between the two clamping wheels. Obviously, in the separated state, the feeding part only needs to set track baffles at both ends of the swab packaging tube, so that the supplied swab packaging tubes can directly enter the clamping area along the feeding channel through the established track. In this implementation mode, the feeding part does not need to adopt complicated mechanical grasping and transfer, which provides technical support for the simplified design of the feeding part.

[0020] 3. The cutting part is configured to reciprocally slide along the axis of the clamped swab packaging tube. In addition, the storage and replenishment device further includes a top block that can move to the gap between the tube body and the tube cap of the clamped swab packaging tube. The cutting part clamps the tube body of the swab packaging tube. When the sealing strip at the gap between the tube body and the tube cap is cut off, and the cutting part clamps the tube body and slides away from the tube cap, the tube cap is blocked by the top block, so that the tube body and the tube cap are separated, which is further convenient for taking the tube cap.

[0021] 4. With the integrated design of the housing, the circular knife can be built in. At the same time, in order to facilitate medical staff to take the unsealed tube cap and the swab body thereon, a bracket is also provided to push the tube cap out of the housing. In addition, when the electric cylinder driving the bracket moves back, it can synchronously drive the cutting part to slide, so that the tube body and the tube cap are separated. The structure is ingenious and does not require the cooperation of multiple power sources, and has the advantages of low cost and small occupied space.

[0022] 5. The feeding power unit is a conveyor belt installed at the opening of the feed hopper. The output end of the conveyor belt points to the feed channel. When the conveyor belt is stationary, it generates a damping force to prevent the swab packaging tube from falling, and when the conveyor belt is running, it generates a driving force to move the swab packaging tube towards the clamping area. The layout structure of this conveyor belt has the advantages of stable transmission and small floor space. Description of the Drawings

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] For the convenience of understanding, in conjunction with the accompanying drawings here, the specific structure and working mode of the present invention are further described as follows:

[0038] The specific structure of the present invention is referred to Figures 1 - 11 As shown, its main structure includes a cutting portion 19 and a feeding portion for storing and continuously supplying the swab packaging tube A to the cutting portion 19 continuously.

[0039] As Figure 1 and Figure 2 shown, the cutting portion 19 includes a motor 194, on the output shaft of the motor 194, a bow-shaped turntable 198 and a driving gear 195 are coaxially fixed. It also includes a supporting bottom wheel 191 coaxially fixed with a driven gear 196 meshing with the driving gear 195, and two swing rods 197 distributed in an inverted V shape. On the lower swing shafts of the two swing rods 197, swinging gears 1971 meshing with each other are coaxially fixed. On the upper cantilever ends of the two swing rods 197, clamping wheels 192 are rotatably fitted. On at least one clamping wheel 192, a circular knife 193 is coaxially fixed. The bow back and bowstring of the bow-shaped turntable 198 are respectively in contact and cooperation with any one of the swing rods 197, so that the two swing rods 197 respectively form a clamping state and a separating state. During the clamping state, the swab packaging tube A is clamped jointly by the supporting bottom wheel 191 and the two clamping wheels 192, and the sealing strip is rolled and cut by the circular knife 193.

[0040] In the initial state, as Figure 3As shown, the bowstring part of the bow-shaped turntable 198 abuts against the swing rod 197, causing the swing rod 197 to be in a separated state. At this time, the feeding part can feed materials between the supporting bottom wheel 191 and the two clamping wheels 192. When the feeding part supplies materials, it is necessary to align the sealing strip at the gap between the tube body A1 and the tube cap A2 of the swab packaging tube A with the annular knife 193. After that, the output shaft of the motor 194 rotates and drives the driving gear 195 and the bow-shaped turntable 198 to rotate. As Figure 4 and Figure 1 shown, the back of the bow of the bow-shaped turntable 198 is used to abut against the swing rod 197 to switch the swing rod 197 to the clamping state. At this time, the supporting bottom wheel 191 and the two clamping wheels 192 jointly clamp the swab packaging tube A to form a three-point stable clamping of the swab packaging tube A. Due to the roller clamping method of the clamping wheel 192 and the supporting bottom wheel 191, it not only prevents the clamped swab packaging tube A from generating radial movement, but also enables the clamped swab packaging tube A to generate a rotational movement around its own axis when the clamping wheel 192 or the supporting bottom wheel 191 generates a rotational movement. Of course, the roller is preferably made of a material with a relatively high coefficient of friction to ensure that sufficient friction force is generated on the clamped swab packaging tube A when the roller rotates. Since the output shaft of the motor 194 rotates and also drives the driving gear 195 to rotate, under the meshing of the driving gear 195 and the driven gear 196, the supporting bottom wheel 191 also generates a synchronous rotational movement. That is, during the period when the motor 194 drives the swing rod 197 to be in the clamping state, the supporting bottom wheel 191 also drives the swab packaging tube A to rotate synchronously, thereby realizing the rolling and cutting of the sealing strip at the gap between the tube body A1 and the tube cap A2 through the annular knife 193. On this basis, in the structural arrangement of the present application, only one power source of the motor 194 is required for the clamping of the swab packaging tube A and the relative rotation of the annular knife 193 around the outer periphery of the swab packaging tube, significantly reducing the space occupied by the cutting part 19, and at the same time reducing the device cost and making the program control simple and not easy to make mistakes. In addition, by using the linkage method of driving the swing rod 197 to rotate by the bow-shaped turntable 198, by changing the angles of the arc section and the straight section of the bow-shaped turntable 198, the duration of the clamping and separation states can be changed; by changing the diameter of the bow-shaped turntable 198, the adjustment of the swing angle of the swing rod 197 can be realized, which is convenient for debugging the swing angle of the swing rod 197 when the device adapts to swab packaging tubes A with different diameters. At the same time, the output shaft of the motor 194 drives the supporting bottom wheel 191 to rotate by the meshing of the driving gear 195 and the driven gear 196. By controlling the gear ratio of the driving gear 195 and the driven gear 196, when the output shaft of the motor 194 rotates one circle, the number of rotations of the supporting bottom wheel 191 can be greater than one circle, ensuring that during the period when the swing rod 197 is in the clamping state, the supporting bottom wheel 191 drives the swab packaging tube A to rotate at least one circumference, so as to ensure that the sealing strips on the outer periphery of the swab packaging tube A are all rolled and cut.

[0041] On the above basis, as Figures 1 - 4As shown, the axes of the supporting bottom wheel 191 and the clamping wheel 192 are horizontally arranged, and the clamping wheels 192 are symmetrically distributed on both sides above the supporting bottom wheel 191. When the swing rod 197 is in the clamping state, the clamping wheels 192 and the outer edges of the supporting bottom wheel 191 jointly form a clamping area for clamping the swab packaging tube A. The swing rod 197 has a tendency to switch to the separation state under normal conditions. Specifically, it can be achieved through a torsion spring, a tension spring or the self-weight of the swing rod 197. In the separation state, a feeding channel for the radial sliding of the swab packaging tube A is formed between the two clamping wheels 192 in the clamping area. Obviously, on the basis that the axes of the supporting bottom wheel 191 and the clamping wheel 192 are horizontally arranged, in the separation state, the feeding part only needs to set track baffles at both ends of the swab packaging tube A, so that the swab packaging tube A supplied by the feeding part can directly enter the clamping area along the feeding channel through the established track. In this implementation mode, the feeding part does not need to adopt cumbersome mechanical grasping and transfer, providing technical support for the simplified design of the feeding part.

[0042] On this basis, as Figure 1 shown, annular knives 193 are coaxially fixed on both of the two clamping wheels 192, further improving the cutting effect on the sealing strip on the outer periphery of the swab packaging tube A.

[0043] On this basis, as Figures 5 - 9 shown, in order to realize the automatic separation of the tube body A1 and the tube cap A2 after the sealing strip is cut, in this application, the cutting part 19 is a structure that can reciprocally slide along the axis of the clamped swab packaging tube A. In addition, the storage and replenishment device further includes a top block 14 that can move to the gap between the tube body A1 and the tube cap A2 of the clamped swab packaging tube A. The clamping area clamps the tube body A1 of the swab packaging tube A. When the sealing strip at the gap between the tube body A1 and the tube cap A2 is cut, and the cutting part 19 clamps the tube body A1 and slides away from the tube cap A2, the tube cap A2 is blocked by the top block 14, so that the tube body A1 and the tube cap A2 are separated. The above-mentioned top block 14 can be an elastic plug in the prior art or a rotating plate similar to a check valve flap as Figure 9 shown or a baffle directly driven by a cylinder, etc., as long as it can prevent the synchronous movement of the tube body A1 and the tube cap A2 when the cutting part 19 clamps the tube body A1 and slides away from the tube cap A2.

[0044] Furthermore, as Figures 5 - 9 and Figure 11 shown, the cutting part 19 and the feeding part are both integrated on the housing 10. The axis of the clamped swab packaging tube A in the clamping area is horizontally arranged. A slide rail 11 parallel to the axis of the clamped swab packaging tube A is fixed on the housing 10. The cutting part 19 is slidably fitted on the slide rail 11 through a slide block 15. Specifically, the supporting bottom wheel 191 is rotationally fitted on the slide block 15, the swinging end of the swing rod 197 is rotationally fitted on the slide block 15, and the motor 194 is fixed on the slide block 15 by bolts; a bracket 13 is also slidably fitted on the slide rail 11 through a slider 12. AsFigure 6 and Figure 8 As shown in states 8a and 8b, when initially receiving the swab packaging tube A, the tail of the tube body A1 of the swab packaging tube A is supported by the bracket 13 and the supporting bottom wheel 191 in the separated state from the swing rod 197, respectively, and the head of the tube cap A2 is supported. This common supporting method enables the length of the supporting bottom wheel 191 not to be too long, providing technical support for the subsequent automatic dropping of the tube body A1. Taking the axial direction from the tube body A1 to the tube cap A2 as the positive direction and the axial direction from the tube cap A2 to the tube body A1 as the negative direction, as Figure 8 shown in state 8c, the bracket 13 sliding forward pushes the tail of the tube body A1, and makes the tube cap A2 protrude out of the housing 10. At this time, the top block 14 and the annular knife 193 are both located at the gap between the tube body A1 and the tube cap A2, and the bracket 13 and the supporting bottom wheel 191 of the cutting part 19 support the tail and the head of the tube body A1, respectively. The slider 12 is driven by the electric cylinder 17 to make a reciprocating sliding motion. A hook part 161 is fixed on the slider 12 through a pull rod 16. After the sealing strip at the gap between the tube body A1 and the tube cap A2 is cut off, as Figure 8 shown in state 8d and Figure 7 as shown, when the electric cylinder 17 drives the slider 12 to slide in the reverse direction and makes the bracket 13 separate from the tail of the tube body A1, the hook part 161 hooks and pulls the sliding seat 15 to move in the reverse direction synchronously, so as to make the tube body A1 and the tube cap A2 generate a separating action; obviously, at this time, the tail of the tube body A1 loses the support of the bracket 13. If the swing rod 197 switches from the clamping state to the separated state at this time, at this time, the tube body A1 loses the clamping of the clamping area, then the tube body A1 will have a tendency to tilt towards the tail. And after the medical staff takes out the tube cap A2 and the swab body A3 carried on the tube cap A2, the tail of the tube body A1 drops towards the tilt, so as to realize the automatic dropping of the tube body A1 after the tube cap A2 is taken out, without the need for manual removal of the tube body A1 from the clamping area. After that, a waste box 30 for receiving the dropped tube body A1 is installed on the housing 10. In addition, since the hook part 161 cannot stably apply a forward movement force to the sliding seat 15, a reset elastic part 18 for driving the sliding seat 15 to slide forward and reset is also installed on the slide rail 11. At the same time, the reset elastic part 18 provides a stable elastic abutting force to the sliding seat 15 that slides forward to the limit position. The integrated design of the housing 10 can integrate the annular knife 193. At the same time, in order to facilitate the medical staff to take the unsealed tube cap A2 and the swab body A3 thereon, a bracket 13 is also provided to push the tube cap A2 out of the housing 10. In addition, when the electric cylinder 17 driving the bracket 13 returns, it can synchronously drive the cutting part 19 to slide, so as to separate the tube body A1 and the tube cap A2. The structure is ingenious and does not require the cooperation of multiple power sources, and has the advantages of low cost and small occupied space.

[0045] As Figure 5 and Figure 10As shown, on the basis that the axes of the above-mentioned clamping wheel 192 and the supporting bottom wheel 191 are horizontally arranged, the feeding part includes a feeding hopper 20. The axes of the swab packaging tubes A are horizontally stacked in the feeding hopper 20. The lower part of the feeding hopper 20 has an opening whose length and width are respectively adapted to the length and diameter of the swab packaging tube A. A feeding power part for continuously supplying the swab packaging tube A to the clamping area is arranged at this opening. So that each time the feeding power part works, only one swab packaging tube A can be fed.

[0046] Specifically, as Figure 10 shown, the feeding power part is a conveyor belt 21 installed at the opening of the feeding hopper 20. The output end of the conveyor belt 21 points to the feeding channel. When the conveyor belt 21 is stationary, it generates a damping force to prevent the swab packaging tube A from falling, and when the conveyor belt 21 runs, it generates a driving force to move the swab packaging tube A towards the clamping area. In actual implementation, the conveyor belt 21 can be arranged as two distributed on both sides of the outlet or a single one distributed on one side wall of the outlet, as long as it can generate a damping force to prevent the swab packaging tube A from falling when stationary and generate a driving force to move the swab packaging tube A towards the clamping area when the conveyor belt 21 runs. The layout structure of the conveyor belt 21 has the advantages of stable transmission and small floor space. Of course, in actual implementation, the feeding power part can also adopt other implementation methods, such as a feeding structure similar to a revolver in the prior art or a transfer structure such as a grasping manipulator.

The storage and replenishment device further includes a top block (14) that can move to the gap between the tube body (A1) and the tube cap (A2) of the clamped swab packaging tube (A). The cutting part (19) clamps the tube body (A1) of the swab packaging tube (A). When the sealing strip at the gap between the tube body (A1) and the tube cap (A2) is cut, and when the cutting part (19) clamps the tube body (A1) and slides away from the tube cap (A2), the tube cap (A2) is blocked by the top block (14), so that a separating action occurs between the tube body (A1) and the tube cap (A2).

5. The swab packaging tube storage and feeding device according to claim 4, characterized in that, The cutting part (19) and the feeding part are both integrated on the housing (10). The cutting part (19) clamps the swab packaging tube (A) in the horizontal direction. A slide rail (11) parallel to the axis of the clamped swab packaging tube (A) is fixed on the housing (10). The cutting part (19) is slidably fitted on the slide rail (11) through a slide block (15). A bracket (13) is also slidably fitted on the slide rail (11) through a slider (12). When initially receiving the swab packaging tube (A), the tail of the tube body (A1) of the swab packaging tube (A) is supported by the bracket (13), and the head of the tube cap (A2) is supported by the supporting bottom wheel (191) in the separated state from the swing rod (197). Taking the axis direction from the tube body (A1) to the tube cap (A2) as the positive direction and the axis direction from the tube cap (A2) to the tube body (A1) as the negative direction, the tail of the tube body (A1) is pushed by the bracket (13) sliding forward, and the tube cap (A2) protrudes out of the housing (10). At this time, the top block (14) and the circular knife (193) are both located at the gap between the tube body (A1) and the tube cap (A2), and the bracket (13) and the cutting part (19) respectively support the tail and the head of the tube body (A1). The slider (12) is driven by an electric cylinder (17) to make a reciprocating sliding motion. A hook part (161) is fixed on the slider (12) through a pull rod (16). After the sealing strip at the gap between the tube body (A1) and the tube cap (A2) is cut off, when the electric cylinder (17) drives the slider (12) to slide in the reverse direction and the bracket (13) is separated from the tail of the tube body (A1), the hook part (161) hooks and pulls the slide block (15) to move in the reverse direction synchronously, so as to cause a separating action between the tube body (A1) and the tube cap (A2). A reset elastic part (18) for driving the slide block (15) to slide forward and reset is also installed on the slide rail (11).

6. The swab packaging tube storage and feeding device according to claim 5, characterized in that, A waste box (30) for receiving the dropped tube body (A1) is installed on the housing (10).
