[0042] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0043] The present invention will be further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0044] See also Figures 1-4The present embodiment provides a conveying mechanism 100, which includes a housing 600, a first driver 410, and a plurality of roller pairs arranged at intervals along the conveying direction, wherein the conveying direction is perpendicular to the length direction of the long strip material; the roller pairs include a plurality of pairs of driving wheels 110 and driven wheels 120 that roll together, wherein the gap between the driving wheels 110 and the driven wheels 120 is used to pass the material, and the driven wheels 120 can be offset in the direction away from the driving wheels 110 when the material passes, and the driven wheels 120 can be reset after the material passes; the first driver 410 10 is connected to each driving wheel 110 and is used to drive each driving wheel 110 to rotate. The roller pair includes a first roller pair 160, which is located on the incoming material side of the ejection mechanism 300. The housing 600 is equipped with a microswitch 510, which triggers the microswitch 510 when the driven wheel 120 in the first roller pair 160 is lifted by the material. The microswitch 510 and the ejection mechanism 300 are both communicatively connected to a controller. The controller is used to control the ejection mechanism 300 to eject the material from the packaging bag when the microswitch 510 is triggered. The first driver 410 can be a first motor. The elongated material can be a cotton swab.

[0045] During operation, a bag containing material is placed at the input of the conveying mechanism 100, and the first driver 410 is activated. Once activated, the first driver 410 drives the driving wheel 110 to rotate, which conveys the material forward. The presence of the driven wheel 120 prevents the bag from slipping, improving conveying reliability. When material is conveyed to the roller pair corresponding to the microswitch 510, the driven wheel 120 in the roller pair is lifted by the material in the bag. This lift triggers the microswitch 510, and the controller controls the ejection mechanism 300 to eject the material from the bag based on the trigger signal from the microswitch 510. This achieves automatic control of the ejection mechanism 300 and improves its intelligence.

[0046] Therefore, the conveying mechanism provided in this embodiment can realize efficient and automatic conveying of materials, thereby realizing efficient and automatic pushing of materials by the pushing mechanism 300, reducing workload, being more efficient, more hygienic, and having a higher degree of intelligence.

[0047] It should be noted that setting the conveying direction of the conveying mechanism 100 perpendicular to the length of the material is beneficial to improving the material conveying efficiency, and can also improve the compactness of the structure. It is small in size and can be set as a small desktop structure, ensuring that the machine is small and lightweight, does not take up too much space, and is convenient for use in medical environments. It is particularly suitable for conveying multiple materials packaged in packaging bags that are connected together, without the need to separate the materials. The overall size of the machine can be 300mm × 220mm × 120mm (length × width × height). At this size, it can handle a variety of materials with a length ranging from 100mm to 200mm.

[0048] In the specific structure of the conveying mechanism 100 provided in this embodiment, a first connecting shaft 130 and several second connecting shafts 140 may also be provided. The driven wheel 120 located on the incoming material side of the ejection mechanism 300 is mounted on the second connecting shaft 140. The first connecting shaft 130 is mounted on the housing 600, and the second connecting shaft 140 is connected to the first connecting shaft 130 via a swinging member 150. The first connecting shaft 130 is rotatably connected to the swinging member 150, and the first connecting shaft 130 and the second connecting shaft 140 are parallel to the axis of the driving wheel 110. Based on the above structure, one or both of the following two structures may be further provided:

[0049] The first method is to set the driven wheel 120 above the corresponding driving wheel 110 so that the driving wheel 110 can support the driven wheel 120. When the material in the packaging bag moves between the driven wheel 120 and the driving wheel 110, the driven wheel 120 can be lifted up, so that the gap between the driving wheel 110 and the driven wheel 120 is enlarged, so that the material can pass through the gap between the driving wheel 110 and the driven wheel 120; and when the material in the packaging bag passes through, the driven wheel 120 can be reset under its own gravity to smoothly press the flat packaging bag and ensure the conveying effect.

[0050] The second method involves installing a torsion spring between the first connecting shaft 130 and the second connecting shaft 140. When the material in the packaging bag moves between the driven wheel 120 and the driving wheel 110, the driven wheel 120 is lifted. The torsion spring adaptively deforms to accommodate the swinging of the second connecting shaft 140, widening the gap between the driving wheel 110 and the driven wheel 120, allowing the material to pass through the gap. Once the material in the packaging bag has passed, the torsion spring drives the driven wheel 120 back to its original position, smoothly pressing down on the flattened packaging bag. Preferably, while the driven wheel 120 is positioned above the corresponding driving wheel 110, a torsion spring is installed between the first connecting shaft 130 and the second connecting shaft 140. This increases the force between the driven wheel 120 and the driving wheel 110, improving conveying stability.

[0051] The above-mentioned roller pair also includes a second roller pair 170. The first roller pair 160, the ejection mechanism 300 and the second roller pair 170 are arranged in sequence along the conveying direction. In this way, the second roller pair 170 and the first roller pair 160 can tighten the packaging bag between them, so that the packaging bag corresponding to the ejection mechanism 300 will be in a taut state, which is conducive to the ejection mechanism 300 to smoothly eject the material in the packaging bag.

[0052] A gear set can be used as a transmission component. A driving gear 710 and a first driven gear 720 can be provided in the gear set. The first driver 410 is connected to the driving gear 710 so that the first driver 410 drives the driving gear 710 to rotate. The rotation of the driving gear 710 can drive the first driven gears 720 to rotate accordingly. The first driven gears 720 are provided in a one-to-one correspondence with the roller pairs, and the first driven gears 720 are coaxially fixedly connected to the driving wheels 110 in the corresponding roller pairs. In this way, the driving wheels 110 in each roller pair can rotate under the drive of the corresponding first driven gear 720. Specifically, the size of the first driven gear 720 can be adjusted according to the required linear speed of each roller pair to ensure stability and accuracy during the material conveying process.

[0053] In addition, two limiters 800 can be provided in the specific structure of the conveying mechanism 100. The two limiters 800 are respectively provided on both sides of the conveying mechanism 100 so as to utilize the two limiters 800 to limit the width of the conveying channel of the conveying mechanism 100, wherein the conveying channel is used for passing materials; the limiters 800 are movably connected to the housing 600, and the limiters 800 can be fixed to the housing 600 at multiple positions along the width direction of the conveying channel. Thus, by adjusting the position of the limiters 800, the width of the conveying channel can be adjusted to accommodate materials of different sizes, thereby enhancing compatibility. In fact, the width direction of the conveying channel is consistent with the length direction of the material. By adjusting the spacing between the two limiters 800, it can accommodate materials of different lengths.

[0054] Specifically, a slide and two groups of slot groups 640 can be provided on the shell 600, and the guide of the slide is set to be consistent with the width direction of the conveying channel, and the limit member 800 is slidably matched with the slide so that the limit member 800 can slide along the slide; the two groups of slot groups 640 are set in a one-to-one correspondence with the two limit members 800, and a plurality of slots arranged along the width direction of the conveying channel are set in each group of slot groups 640, and a hook is provided on the limit member 800, and the hook is set to be able to elastically engage with any slot in the corresponding slot group 640. In this way, when the limit member 800 is pulled along the slide, the hook on the limit member 800 can slide from one slot in the corresponding slot group 640 to another slot. After the limit member 800 moves into place, the hook on the limit member 800 can cooperate with a slot in the corresponding slot group 640, and the slot can realize the positioning of the limit member 800, which is convenient for adjustment. The limiting member 800 may be manufactured using a material having a certain toughness, so that the hook has a certain elasticity, thereby facilitating the hook to move between the various slots in the slot group 640 .

[0055] A guide structure may also be provided to guide the pushed-out material to the outlet 620 , thereby facilitating smooth exit of the material.

[0056] Furthermore, a first photoelectric switch 520 and an alarm can be provided to detect the presence of material on the incoming material side of the ejection mechanism 300 using the first photoelectric switch 520. Both the first photoelectric switch 520 and the alarm are communicatively connected to the controller. When the first photoelectric switch 520 detects no material, it indicates that the material is exhausted. At this time, the controller can control the alarm to sound an alarm based on the corresponding signal sent by the first photoelectric switch 520, thereby reminding the user to replenish the material in time. Specifically, the alarm can be a buzzer.

[0057] Furthermore, a second photoelectric switch 530 may be provided to detect the presence of material at the outlet 620. The outlet 620 is the material ejection side of the ejection mechanism 300. When the material is ejected, it extends out of the outlet 620. The second photoelectric switch 530 and the first driver 410 are both communicatively connected to the controller. When the second photoelectric switch 430 detects the presence of material at the outlet 620, it indicates that the unpacked material has not yet been removed. At this point, the controller can control the first driver 410 to stop based on a corresponding signal sent by the second photoelectric switch 430, causing the conveying mechanism 100 to no longer convey the material. When the second photoelectric switch 530 detects the absence of material at the outlet 620, it indicates that the material has been removed or has not yet been conveyed to the outlet 620. At this point, the controller can control the first driver 410 to start based on a corresponding signal sent by the second photoelectric switch 530, causing the conveying mechanism 100 to continue conveying the material.

[0058] See also Figure 5-Figure 7 This embodiment also provides an automatic package unpacking machine, which includes an ejection mechanism 300 and the aforementioned conveying mechanism 100. The ejection mechanism 300 includes a second driver 420, a lead screw 320, a nut 330, and a guide rail 340. The length of the lead screw 320 and the guide rail 340 are parallel to the conveying direction. The second driver 420 is connected to the lead screw 320 to drive the lead screw 320 to rotate. The lead screw 320 cooperates with the nut 330, and the guide rail 340 is slidably connected to the nut 330. The nut 330 is fixed with a push block 310 for ejecting the material. The second driver 420 can be a second motor.

[0059] In the automatic bag unpacking machine provided in this embodiment, the second driver 420 drives the lead screw 320 to rotate, which in turn drives the nut 330 to move along the guide rail 340. Consequently, the push block 310 pushes the material along its length. Furthermore, because the automatic bag unpacking machine provided in this embodiment includes the aforementioned conveying mechanism 100, it possesses all the advantages of the aforementioned conveying mechanism 100, enabling efficient and automated material conveyance. This enables efficient and automated material ejection by the ejection mechanism 300, reducing workload, increasing efficiency, improving hygiene, and providing a high level of intelligence.

[0060] Furthermore, a proximity switch 540 and a third photoelectric switch 550 may be provided in the specific structure of the automatic unpacking machine provided in this embodiment. When the push block 310 of the ejection mechanism 300 moves from the initial position to the end position, the material can be pushed out from the incision of the packaging bag; wherein, the proximity switch 540 can detect whether the push block 310 has reached the end position, and the third photoelectric switch 550 can detect whether the push block 310 has reached the initial position. The proximity switch 540, the third photoelectric switch 550 and the second driver 420 are all connected to the controller for communication. When the proximity switch 540 detects that the push block 310 has reached the end position, it indicates that the material has been pushed into place. At this time, the controller can control the second driver 420 to stop and then reverse and start according to the signal sent by the proximity switch 540, and use the second driver 420 to drive the push block 310 of the ejection mechanism 300 to move in the opposite direction toward the initial position; when the third photoelectric switch 550 detects that the push block 310 has reached the initial position, it indicates that the ejection mechanism 300 has been reset. At this time, the controller can control the second driver 420 to stop according to the signal sent by the third photoelectric switch 550, so that the ejection mechanism 300 maintains the current state to facilitate the ejection of the next material.

[0061] In the automatic packaging machine provided in this embodiment, a bag cutting mechanism 200 may also be provided. The bag cutting mechanism 200 and the ejection mechanism 300 are arranged sequentially along the conveying direction of the conveying mechanism 100. The bag cutting mechanism 200 and the conveying mechanism 100 are both connected to the first drive. The bag cutting mechanism 200 and the conveying mechanism 100 operate synchronously. When the packaging bag reaches the bag cutting mechanism 200, the bag cutting mechanism 200 can cut one end of the packaging bag to form an incision at one end of the packaging bag. It should be noted that the incision formed in the packaging bag by the bag cutting mechanism 200 can greatly reduce the resistance encountered by the packaging bag when the material is ejected, allowing the material to be smoothly ejected from the incision of the packaging bag. At the same time, it can also reduce the force applied to the packaging bag when the material is ejected, thereby reducing the deformation of the packaging bag. In addition, the risk of the material being unable to be smoothly ejected due to excessive deformation of the packaging bag is reduced, thereby improving the stability and reliability of the equipment operation. By connecting both the conveying mechanism 100 and the bag cutting mechanism 200 to the first driver 410, the conveying mechanism 100 and the bag cutting mechanism 200 can operate synchronously. Thus, each time the conveying mechanism 100 conveys a packaging bag to the bag cutting mechanism 200, the bag cutting mechanism 200 can complete the cutting of a packaging bag. This not only meets the requirements of conveying and bag cutting, but also reduces the number of drivers, reduces costs, and simplifies the control logic.

[0062] The second driven gear 730 is coaxially fixedly coupled to the cutter 210. Thus, when the second driver 420 rotates the driving gear 710, the driving gear 710 drives the second driven gear 730 to rotate synchronously. Consequently, the second driven gear 730 drives the cutter 210 to cut the packaging bag. Specifically, the size of the first driven gear 720 can be adjusted based on the required linear speed of each roller pair to ensure stable and accurate material conveyance. The size of the second driven gear 730 can also be adjusted based on the required rotational speed of the cutter 210.

[0063] The above-mentioned roller pair also includes a third roller pair 180. The third roller pair 180, the bag cutting mechanism 200, the first roller pair 160, the ejection mechanism 300 and the second roller pair 170 are arranged in sequence along the conveying direction. In this way, the third roller pair 180 and the first roller pair 160 can tighten the packaging bag between them, so that the packaging bag corresponding to the bag cutting mechanism 200 will be in a taut state, which is conducive to the bag cutting mechanism 200 to cut the packaging bag.

[0064] A flip cover 900 may be provided at the input port 630 of the housing 600, and the third roller pair 180 is located below the flip cover 900, rotatably connecting the flip cover 900 to the housing 600, and connecting the flip cover 900 to the second connecting shaft 140 in the third roller pair 180 via a pulling member 190. The pulling member 190 allows the second connecting shaft 140 to swing up and down relative to the flip cover 900, and can also drive the second connecting shaft 140 to be lifted when the flip cover 900 is opened to facilitate the insertion of materials.

[0065] The specific structure of the bag cutting mechanism 200 may also include a roller cutter 210 and an auxiliary wheel 220. The first driver 410 is connected to the roller cutter 210 via a gear set so that the first driver 410 drives the roller cutter 210 to rotate. The auxiliary wheel 220 is rotatably mounted on the housing 600, and the roller cutter 210 and the auxiliary wheel 220 are rolled together to pass the material through the gap between the auxiliary wheel 220 and the roller cutter 210. In this way, when the roller cutter 210 rotates, it can cooperate with the auxiliary wheel 220 to cut the packaging bag. It should be noted that using the combined structure of the roller cutter 210 and the auxiliary wheel 220 to cut the packaging bag can reduce the pulling force on the packaging bag during cutting, thereby reducing the impact of the cutting process on the overall material conveying, allowing the material to be smoothly conveyed by the conveying mechanism 100.

[0066] The bag cutting mechanism 200 may specifically include a third connecting shaft 230 and an elastic member. The cutter 210 is coaxially fixedly coupled to the third connecting shaft 230. An arcuate slot 610 is defined in the housing 600, and the third connecting shaft 230 is slidably engaged with the arcuate slot 610. This allows the third connecting shaft 230 to be moved along the arcuate slot 610 to adjust the position of the cutter 210. This allows the distance between the cutter 210 and the auxiliary wheel 220 to be adjusted, increasing the distance and facilitating the removal of remaining material from the machine. An elastic member may be connected between the housing 600 and the third connecting shaft 230. The elastic force applied by the elastic member to the third connecting shaft 230 is directed toward the auxiliary wheel 220. This allows the cutter 210, mounted on the third connecting shaft 230, to press against the auxiliary wheel 220 without external force. The elastic member also increases the pressure of the cutter 210 on the bag, improving the cutting effect. The elastic member may be a spring 240.

[0067] Preferably, an annular groove can be provided on the wheel surface of the auxiliary wheel 220, and the blade of the hob 210 is matched with the annular groove, so that the auxiliary wheel 220 can provide stable support force for the packaging bag and ensure a smooth cutting process.

[0068] Furthermore, the cross-sectional shape of the annular groove may be set to be V-shaped, which can improve the supporting effect of the auxiliary wheel 220 on the packaging bag, thereby optimizing the cutting effect.

[0069] A second driven gear 730 can be provided in the gear train and coaxially fixedly connected to the cutter 210. Thus, when the second driver 410 drives the driving gear 710 to rotate, the driving gear 710 can drive the second driven gear 730 to rotate synchronously therewith. Furthermore, the second driven gear 730 can drive the cutter 210 to rotate, thereby cutting the packaging bag. Specifically, the size of the second driven gear 730 can be adjusted according to the required rotational speed of the cutter 210.

[0070] The bag cutting mechanism 200 may further include an adjusting member 250. Among the plurality of first driven gears 720, there is a first driven gear 720 meshing with the second driven gear 730. The first driven gear 720 is rotated to match the adjusting member 250, and the adjusting member 250 is rotated to match the third connecting shaft 230. In fact, the first driven gear 720 and the third connecting shaft 230 are respectively rotated to match two parts of the adjusting member 250. When it is necessary to adjust the distance between the hob 210 and the auxiliary wheel 220, the adjusting member 250 can be pulled. 0, so that the adjusting member 250 swings around the axis of the corresponding first driven gear 720, so that the third connecting shaft 230 slides along the arc groove 610, and at the same time, the second driven gear 730 can roll along the first driven gear 720 meshing with it. Under the support of the first driven gear 720, the second driven gear 730 can roll smoothly, so that in the process of adjusting the position of the hob 210, the structural stability of the hob 210 can be guaranteed, and after releasing the adjusting member 250, the hob 210 can return to the cutting position by itself.
