[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] With the continuous development of medical technology and the growing demand for medical services, the automation and intelligentization of medical equipment have become important means to improve the quality and efficiency of medical services. Cotton swabs, as common medical supplies, are in huge demand during medical procedures. However, the traditional method of unpacking cotton swabs requires medical staff to do it manually, which is not only labor-intensive and inefficient, but also poses certain health risks.

[0050] To improve the above problems, an embodiment of the present invention provides an automatic packaging unpacking device and a control method. The embodiment of the present invention is described in detail below.

[0051] This embodiment provides an automatic packaging device. Figure 1 The automatic unpacking device shown in the figure comprises: a controller 11 and a conveying device 12, a bag cutting device 13 and a pushing device 14 connected to the controller; Figure 1 As shown, the bag cutting device 13 is located at the first end of the conveying device 12, and the first end of the pushing device 14 is provided with an outlet.

[0052] The outdoor communication mode between the controller 11 and the conveying device 12, the bag cutting device 13 and the pushing device 14 can be wired communication or wireless communication.

[0053] The controller 11 is used to control the conveying device 12 to transport the unpacked objects at the input port to the pushing station upon receiving the unpacking start signal; the conveying starting point of the conveying device 12 is the input port, and the conveying end point is the location of the pushing device 14;

[0054] The bag cutting device 13 includes a blade; the controller 11 is further configured to drive the blade to cut off the first end package seal of the packaged object to be unpacked passing through the bag cutting device 13 during the transport process of the packaged object to be unpacked, so that the first end of the packaged object to be unpacked becomes an open end;

[0055] The blade of the bag cutting device 13 is arranged at the first end of the conveying device. When the packaged object to be unpacked is transported from the input port to the pushing station, it will pass through the bag cutting station. The position of the blade can be set according to the size of the packaged object to be unpacked so that the package seal at the first end of the packaged object to be unpacked passes through the cutting area of ​​the blade, thereby cutting off the package seal at the first end of the packaged object to be unpacked, making it easier to push out the target object in the package and reducing the pushing resistance.

[0056] The first end of the pushing device 14 is provided with an outlet. The controller 11 is also used to control the pushing device 14 to push the target object in the package of the unpacked object to be unpacked through the open end to the outlet when the unpacked object with the packaging seal cut off at the first end reaches the pushing station.

[0057] The above-mentioned outlet is arranged at the first end of the pushing device 14, in the same direction as the setting direction of the blade (such as, Figure 1 The middle bag cutting device 14 and the outlet are respectively arranged at the lower ends of the conveying device 12 and the pushing device 14 so as to push the target object in the package from the package opening to the outlet.

[0058] The objects to be unpacked may be a row of cotton swab bags each containing a cotton swab, or a row of disinfection sticks or other medical supplies each containing a separate package.

[0059] The above-mentioned automatic unpacking equipment provided in this embodiment integrates a conveying device, a bag cutting device and a pushing device into the automatic unpacking equipment, so as to automatically peel out the packaged medical supplies individually and automatically push the peeled medical supplies to the outlet, thereby saving unpacking time, improving unpacking efficiency, and reducing the risk of contamination of medical supplies during manual unpacking.

[0060] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a first detection device and an alarm device connected to the controller in communication; the first detection device is arranged at the input port;

[0061] The controller is also used to determine whether there is an object to be unpacked at the input port based on the feedback signal of the first detection device. When there is no object to be unpacked at the input port, the controller controls the alarm device to sound an alarm to prompt the user to replenish the object to be unpacked.

[0062] The above-mentioned first detection device can be a photoelectric switch. The transmitter and receiver of the photoelectric switch can be respectively arranged at the top and bottom of the input port. When there is an object to be unpacked at the input port, the light emitted by the transmitter will be blocked. The intensity of the light received by the photoelectric switch receiver can be used to determine whether there is an object to be unpacked at the input port.

[0063] The alarm device may be a buzzer. When the first detection device detects that the input port is insufficiently stocked, the alarm device sounds an alarm to prompt the staff to replenish the objects to be unpacked in a timely manner.

[0064] In one embodiment, the conveying device provided in this embodiment includes a first motor and a plurality of transmission assemblies, and the first motor is electrically connected to the controller;

[0065] The controller is used to send a rotational electrical signal to the first motor when receiving the unpacking start signal, so that the first motor drives the transmission component to drive the object to be unpacked to move toward the pushing device.

[0066] The transmission assembly can be a conveyor belt or a plurality of rollers or other transmission parts. The motor drives the transmission assembly through a transmission mechanism such as a gear set to transmit the objects to be unpacked to the pushing station.

[0067] The above-mentioned automatic unpacking device can be provided with a start button. When the user presses the start button, the controller receives the unpacking start signal input by the user, and sends a rotation direction electrical signal and a pulse signal to the first motor to control the motor speed. The first motor drives the transmission assembly through the transmission mechanism to move the object to be unpacked toward the pushing device.

[0068] In one embodiment, the blade provided in this embodiment is a rolling blade, and the bag cutting device further includes a second motor, and the second motor is electrically connected to the controller;

[0069] The controller is used for sending a rotation electric signal to the second motor when receiving the unpacking start signal so that the second motor drives the roller to rotate, so as to cut off the first end packaging seal of the packaged object to be unpacked passing through the bag cutting station.

[0070] The first motor and the second motor may be the same motor or different motors.

[0071] The above-mentioned roller is used to cut the packaging bag of the packaged object to be unpacked to ensure that the target object in the package can be peeled out smoothly. The roller serves as a cutting tool, and its power comes from the second motor. The second motor can be driven by a gear set to drive the roller to quickly cut the first end packaging seal of the packaged object to be unpacked.

[0072] When the packaged objects are transferred from the input port to the push station, the first end of the package seal will pass through the cutting station where the roller is located. When it reaches the cutting station, the seal will be automatically cut off, saving bag cutting time and improving unpacking efficiency.

[0073] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a detection component electrically connected to the controller, the pushing device including a third motor, a guide groove and a pushing block, the third motor being electrically connected to the controller; the detection component is used to detect whether the object to be unpacked has reached the guide groove position;

[0074] The outlet is located at the first end of the guide groove, and the initial position of the push block is located at the second end of the guide groove;

[0075] The controller is also used to determine whether the object to be unpacked reaches the guide groove based on the feedback signal of the detection component. When the object to be unpacked reaches the guide groove, the controller controls the third motor to rotate forward to drive the push block to move toward the first end of the guide groove.

[0076] The detection assembly can be a sensor, such as a microswitch, located at the end of the conveyor or at the push station. When the unpacked object reaches the push station, it can provide a feedback signal to the controller. The third motor can drive the push block along the guide slot via a transmission mechanism, such as a lead screw assembly. When the third motor rotates forward, the push block moves from the second end of the guide slot toward the first exit, pushing the object out of the package through the first opening and continuing to the exit, where it awaits access by a staff member.

[0077] In order to facilitate the pushing of the target object, a guide groove can be set at the pushing station, and the first end of the guide groove can be connected to the outlet, so that the pushing block in the guide groove can smoothly push the target object in the package to be unpacked after the first end seal is cut off to the outlet.

[0078] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a proximity switch; the proximity switch is electrically connected to the controller;

[0079] The controller is also used to determine whether the push block reaches the preset position based on the feedback signal of the proximity switch, and when the push block reaches the preset position, determine that the target object reaches the exit, and control the third motor to stop rotating.

[0080] The proximity switch may be located at a preset position, which corresponds to the position of the push block when the push block pushes the target object to the exit. When the push block reaches the preset position, the proximity switch is activated. When the controller detects the activation of the proximity switch, it determines that the push block has reached the preset position, i.e., that the target object in the package has been pushed to the exit. The controller then sends a stop signal to the third motor, i.e., stops sending pulse signals to the third motor.

[0081] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a second detection device; the second detection device is located at the initial position of the push block;

[0082] The controller is also used to control the third motor to reverse after the push block reaches the preset position and the third motor stops rotating, so as to drive the push block to move to the initial position, and to judge in real time whether the push block has returned to the initial position based on the feedback signal of the second detection device. When the push block reaches the initial position, the third motor is controlled to stop rotating.

[0083] When the push block reaches the preset position, the controller controls the third motor to stop rotating, and then sends a reverse signal to the third motor to drive the push block to move from the first end of the guide slot to the initial position at the second end in preparation for the next push.

[0084] A second detection device can be provided at the second end of the guide groove. The second detection device can be an object detection sensor such as a photoelectric switch. The controller can determine whether the push block has returned to the initial position based on the feedback signal of the second detection device. When the push block reaches the second end of the guide groove, the signal fed back to the controller by the second detection device changes. The controller determines that the push block has reached the second end of the guide groove, controls the third motor to stop rotating, and keeps the push block at the initial position.

[0085] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a third detection device electrically connected to the controller; the third detection device is arranged at the outlet;

[0086] The controller is used to determine whether the target object at the warehouse opening has been taken away based on the feedback signal of the third detection device, and control the conveying device to stop running when the target object has not been taken away. After the target object is taken away, the controller controls the conveying device to transfer the next object to be unpacked to the pushing station.

[0087] The above-mentioned third detection device can be an object detection sensor such as a photoelectric switch. The controller can determine whether the target object at the outlet has been taken away based on the feedback signal of the third detection device. When the target object at the outlet has not been taken away, the first motor of the conveying device is controlled to stop running to stop the conveying device; when the target object at the outlet is taken away, the signal fed back to the controller by the third detection device changes, and the first motor of the conveying device is controlled to continue running to prepare for the next unpacking and pushing.

[0088] In one embodiment, the controller may be a programmable logic controller (PLC), and the motors may be stepper motors.

[0089] In one embodiment, it is assumed that the object to be unpacked is a cotton swab. Figure 2 The programmable logic controller wiring diagram shown is Figure 2 The figure shows the wiring diagram of each connection port of the PLC controller and each sensor and motor. The first detection device to the third detection device are photoelectric switches 1 to 3 respectively. The alarm device is a buzzer. The first motor and the second motor are the same motor 1. The third motor is motor 2. The motor 1 is a 42 stepper motor and the motor 2 is a 28 stepper motor. The detection component is a micro switch. The Y3 and Y2 ports control the direction and speed of motor 1 respectively. The Y1 and Y0 ports control the direction and speed of motor 2 respectively. Figure 2 KA1 to KA6 are current relays that protect the motor and sensor circuits from overload and short circuits. The PLC controller is also electrically connected to the device's on / off button. When the button is pressed, the PLC controller receives a signal to start unpacking.

[0090] The automatic unpacking equipment provided in this embodiment includes three modules: a sensor perception system, a PLC control system, and an execution system. The sensor perception system is responsible for real-time monitoring of the cotton swab conveying, bag cutting, and ejection process, and provides accurate feedback signals to the controller. It includes sensors such as photoelectric switches, proximity switches, and micro switches. The PLC control system, as its core, integrates a signal converter and a PLC controller to receive sensor signals, perform logical judgments, and output control instructions. The execution system, based on the PLC instructions, uses actuators such as stepper motors to realize functions such as automatic conveying, bag cutting, and ejection of cotton swabs.

[0118] Step S412: Control the first motor and the second motor to stop running, and return to step S411.

[0119] Before the machine is operated, the operator neatly places a row of individually packaged cotton swab bags into the input port of the conveyor device, connects the power supply, presses the start button, and the machine begins to work automatically; the conveyor device inside the machine will transfer the cotton swab bags one by one to the bag cutting device, and after cutting, they will continue to be transferred to the pushing device; the pushing device will push the single cotton swab to the outlet, waiting for the staff to use it. The machine is equipped with an automatic sensing system (third detection device) that can detect the cotton swab's exit status in real time. Once it senses that the cotton swab has been taken away, it will immediately prepare to push out the next cotton swab. In addition, the machine also has an inventory detection function (first detection device). When the internal cotton swabs are exhausted, a prompt sound will be issued through the alarm device to remind the operator to replenish the cotton swabs in time.

[0120] Corresponding to the automatic unpacking equipment provided in the above embodiment, see Figure 5-Figure 11 An embodiment of the present invention provides an automatic cotton swab unpacking machine, comprising a first driver 410 (i.e., the first and second motors described above), a second driver 420 (i.e., the third motor described above), a conveying device 100, a bag cutting device 200, and a pushing device 300. The bag cutting device 200 and the pushing device 300 are arranged sequentially along the conveying direction of the conveying device 100. The conveying device 100 and the bag cutting device 200 are both connected to the first driver 410, and the conveying device 100 and the bag cutting device 200 operate synchronously. The pushing device 300 is connected to the second driver 420. The conveying device 100 is used to drive and transport the cotton swab bags, the bag cutting device 200 is used to cut the first end of the cotton swab bags, and the pushing device 100 is used to push the cotton swabs out of the incision of the cotton swab bags. On the incoming side of the pushing device 300, the cotton swab bags each contain cotton swabs.

[0121] During use, a cotton swab bag containing cotton swabs is placed at the input port of the conveying device 100, and the first driver 410 is controlled to start working, driving the conveying device 100 and the bag cutting device 200 to operate synchronously. The conveying device 100 can convey the cotton swab bag along the conveying direction. Under the conveying of the conveying device 100, the cotton swab bag will pass through the bag cutting device 200 and the pushing device 300 in sequence; when the cotton swab bag reaches the bag cutting device 200, the bag cutting device 200 can cut one end of the cotton swab bag to form an incision at one end of the cotton swab bag; when the cotton swab bag with the incision reaches the pushing device 300, the second driver 420 is controlled to drive the pushing device 300 to push the cotton swabs in the cotton swab bag, so that the cotton swabs are pushed out of the incision of the cotton swab bag, realizing automatic unpacking of the cotton swabs.

[0122] In the specific structure of the automatic cotton swab unpacking machine provided in this embodiment, a shell 600 can be set. The above-mentioned conveying device 100, bag cutting device 200 and pushing device 300 can all be installed in the shell 600. The shell 600 is provided with an input port 630, an output port and an outlet port 620. The input port 630 is opposite to the input end of the conveying device 100 and is used for placing the cotton swab bag; the output port is opposite to the output end of the conveying device 100 and is used for outputting discarded empty bags; the outlet port 420 is opposite to the pushing device 300 and is used for outputting the cotton swabs pushed out of the cotton swab bag.

[0123] like Figure 8 As shown, the automatic cotton swab unpacking machine provided in this embodiment also includes a first photoelectric switch 520 (i.e., the above-mentioned first detection device), a second photoelectric switch 550 (i.e., the above-mentioned second detection device), a third photoelectric switch 530 (i.e., the above-mentioned third detection device) and a proximity switch 540. The first photoelectric switch 520, the second photoelectric switch 550, the third photoelectric switch 530 and the proximity switch 540 can all be installed on the housing 600.

[0124] A transmission assembly may also be provided in the specific structure of the automatic cotton swab unpacking machine provided in this embodiment. In the specific structure of the conveying device 100, a plurality of roller groups may be provided at intervals along the conveying direction. The roller groups may specifically include a plurality of pairs of driving wheels 110 and driven wheels 120 that cooperate with each other in rolling manner. The gap between the driving wheel 110 and the driven wheel 120 can allow the cotton swab bag to pass through it. The driving wheels 110 in the same group of roller pairs are coaxially arranged, and the first driver 410 is connected to the driving wheels 110 through the transmission assembly, so that the first driver 410 can drive the driving wheels 110 to rotate synchronously through the transmission assembly. The rotation of the driving wheel 110 can convey the cotton swab bag forward. The presence of the driven wheel 120 makes the cotton swab bag less likely to slip, thereby improving the conveying reliability.

[0125] Typically, cotton swab bags are long and thin. Setting the conveying direction of the conveying device 100 perpendicular to the length of the cotton swabs improves the efficiency of conveying the cotton swab bags. It also increases the compactness of the structure, resulting in a smaller size. It can be configured as a small desktop structure, ensuring that the machine is compact and lightweight, does not take up excessive space, and is convenient for use in medical environments. It is particularly suitable for conveying multiple cotton swab bags connected together, without the need to separate the bags. The overall size of the machine can be 300mm × 220mm × 120mm (length × width × height). At this size, it can handle cotton swabs of various specifications ranging in length from 100mm to 200mm.

[0126] In the specific structure of the conveying device 100, a first connecting shaft 130 and several second connecting shafts 140 are set, and the driven wheel 120 is set above the corresponding driving wheel 110, so that the driving wheel 110 can support the driven wheel 120; the driven wheel 120 located on the incoming material side of the pushing device 300 is installed on the second connecting shaft 140, the first connecting shaft 130 is installed on the housing 600, and the second connecting shaft 130 is connected to the first connecting shaft 130 through the swing member 150, wherein the first connecting shaft 130 and the swing member 150 is rotatably connected, and the first connecting shaft 130 and the second connecting shaft 140 are parallel to the axis of the driving wheel 110. In this way, when the cotton swab in the cotton swab 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 widened, so that the cotton swab can pass through the gap between the driving wheel 110 and the driven wheel 120; and when the cotton swab in the cotton swab bag passes through, the driven wheel 120 can fall back to smoothly press the flat cotton swab bag to ensure the conveying effect.

[0127] A torsion spring can also be provided between the first connecting shaft 130 and the second connecting shaft 140. When the cotton swab in the cotton swab bag moves between the driven wheel 120 and the driving wheel 110, the driven wheel 120 can be lifted up, and the torsion spring can produce adaptive deformation to adapt to the swing of the second connecting shaft 140; and when the cotton swab in the cotton swab bag passes through, the torsion spring can drive the driven wheel 120 to reset, which can increase the force between the driven wheel 120 and the driving wheel 110 and improve the conveying smoothness.

[0128] The above-mentioned roller pair may include a first roller pair 160, which is located between the bag cutting device 200 and the pushing device 300; a micro switch 510 (i.e., the above-mentioned detection component) can be installed on the shell 600, and the micro switch 510 can be triggered when the driven wheel 120 in the first roller pair 160 is lifted by the cotton swab; the micro switch 510 and the second driver 420 are both communicatively connected to the controller. When the micro switch 510 is triggered, the controller can control the second driver 420 to drive the pushing device 300 to push the cotton swab out of the incision of the cotton swab bag, thereby realizing automatic opening of the second driver 420 and improving the level of intelligence.

[0129] The above-mentioned roller pair also includes a second roller pair 170 and a third roller pair 180. The second roller pair 170, the bag cutting device 200, the first roller pair 160, the pushing device 300 and the third roller pair 180 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 cotton swab bag between the two, so that the cotton swab bag corresponding to the bag cutting device 200 will be in a taut state, which is conducive to the bag cutting device 200 to cut the cotton swab bag; similarly, the first roller pair 160 and the third roller pair 180 can tighten the cotton swab bag between the two, so that the cotton swab bag corresponding to the pushing device 300 will be in a taut state, which is conducive to the pushing device 300 to smoothly push the cotton swabs in the cotton swab bag.

[0130] The specific structure of the bag cutting device 200 can also include a roller cutter 210 and an auxiliary wheel 220. The first driver 410 is connected to the roller cutter 210 via a transmission assembly so that the first driver 410 can drive 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 cotton swab bag 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 cotton swab bag. It should be noted that using the combined structure of the roller cutter 210 and the auxiliary wheel 220 to cut the cotton swab bag can reduce the pulling force on the cotton swab bag during cutting, thereby reducing the impact of the cutting process on the overall conveying of the cotton swab bag, allowing the cotton swab bag to be smoothly conveyed by the conveying device 100.

[0131] The bag cutting device 200 may specifically include a third connecting shaft 230 and an elastic member. The blade 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. The third connecting shaft 230 can be moved along the arcuate slot 610 to adjust the position of the blade 210. This allows for adjustment of the distance between the blade 210 and the auxiliary wheel 220, increasing this distance and facilitating the removal of remaining cotton swabs 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. Thus, in the absence of external force, the blade 210 mounted on the third connecting shaft 230 can press against the auxiliary wheel 220. The elastic member also increases the pressure of the blade 210 on the cotton swab bag, improving the cutting effect. The elastic member may be a spring 240.

[0132] Preferably, an annular groove can be provided on the wheel surface of the auxiliary wheel 220, and the blade of the roller 210 is matched with the annular groove, so that the auxiliary wheel 220 can provide stable support force for the cotton swab bag and ensure a smooth cutting process.

[0133] 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 cotton swab bag, thereby optimizing the cutting effect.

[0134] A gear set can be used as the transmission assembly. A driving gear 710, a first driven gear 720, and a second driven gear 730 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 drives the first driven gear 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, thereby driving the conveying device 100. The second driven gear 730 is coaxially fixedly connected to the roller cutter 210. Therefore, when the second driver 420 drives the driving gear 710 to rotate, the driving gear 710 can drive the second driven gear 730 to rotate synchronously. Furthermore, the second driven gear 730 can drive the roller cutter 210 to rotate, thereby cutting the cotton swab bag. Specifically, the size of the first driven gear 720 can be adjusted according to the linear speed required by each set of roller pairs to ensure the stability and accuracy of the cotton swab during transportation; the size of the second driven gear 730 can be adjusted according to the required rotation speed of the hob 210.

[0135] The bag cutting device 200 may further include an adjusting member 250, and the third connecting shaft 230 may be rotationally engaged with a portion of the adjusting member 250. If a first driven gear 720 is meshed with a second driven gear 730, the first driven gear 720 may be rotationally engaged with another portion of the adjusting member 250. If the driving gear 710 is directly meshed with the second driven gear 730, the driving gear 710 may be rotationally engaged with another portion 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 to swing the adjusting member 250 around the axis of the corresponding first driven gear 720 or the axis of the driving gear 710, so that the third connecting shaft 230 slides along the arc groove 610. At the same time, the second driven gear 730 can roll along the first driven gear 720 or the driving gear 710 engaged therewith. Under the support of the first driven gear 720 or the driving gear 710, the second driven gear 730 can roll smoothly. Therefore, in the process of adjusting the position of the hob 210, the structural stability of the hob can be guaranteed, and after releasing the adjusting member, the hob 210 can return to the cutting position by itself.

[0136] Furthermore, the specific structure of the automatic cotton swab unpacking machine can also include two limiters 800, which are positioned on either side of the conveying device 100. These limiters 800 can be used to limit the width of the conveying channel of the conveying device 100, where the conveying channel is used to allow the cotton swab bags to pass through. The limiters 800 are movably connected to the housing 600 and can be fixed to the housing 600 at multiple positions along the width of the conveying channel. Thus, by adjusting the position of the limiters 800, the width of the conveying channel can be adjusted to accommodate cotton swab bags of different sizes, providing greater compatibility. In fact, the width of the conveying channel is consistent with the length of the cotton swabs, and by adjusting the spacing between the two limiters 800, cotton swab bags of different lengths can be accommodated.

[0137] 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 can be made of a material with a certain toughness, so that the hook has a certain elasticity, which facilitates the hook to move between the various slots in the slot group 640.

[0138] In the specific structure of the pushing device 300, a lead screw 320, a nut 330 and a guide rail 340 can be provided, and the length direction of the lead screw 320 and the guide of the guide rail 340 are set to be parallel to the length direction of the cotton swab, and the second driver 420 is connected to the lead screw 320 so that the second driver 420 can drive the lead screw 320 to rotate; the lead screw 320 is matched with the nut 330, and the guide rail 340 is slidably connected to the nut 330, and a push block 310 for pushing the cotton swab out is fixed on the nut 330. In this way, the rotation of the lead screw 320 can drive the nut 330 to move along the guide rail 340, and then the push block 310 can push the cotton swab out along its length direction.

[0139] Furthermore, the pushing device 300 may further include a guide groove 350 , so as to guide the pushed-out cotton swab to the outlet 620 through the guide groove 350 , thereby facilitating smooth exit of the cotton swab from the outlet.

[0140] A flip cover 900 may be provided at the input port of the housing 600, and the second roller pair 170 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 second roller pair 170 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 the cotton swab bag.

[0141] The automatic cotton swab unpacking machine provided in this embodiment can place multiple cotton swab bags containing cotton swabs at one time and can automatically peel out each one. The user only needs to take away the cotton swabs, and the machine can automatically remove the discarded empty bags and prepare for the next operation.

[0142] Before the machine is operated, the operator neatly places a row of individually packaged cotton swab bags into the input port of the conveying device 100, turns on the power, presses the start button, and the machine starts to work automatically; the conveying device 100 inside the machine will convey the cotton swab bags one by one to the bag cutting device 200, and after cutting, they will continue to be conveyed to the pushing device 300; the pushing device 300 will push a single cotton swab to the outlet 620, waiting for the staff to take it.
