[0044] During use, the material enclosed in the packaging bag is placed at the input port of the conveying mechanism, and the first driver is controlled to start working, driving the conveying mechanism and the bag cutting mechanism to operate synchronously. The conveying mechanism can transport the material along the conveying direction. Under the conveying mechanism, the material enclosed in the packaging bag passes through the bag cutting mechanism and the ejection mechanism in sequence. When the material enclosed in the packaging bag reaches the bag cutting mechanism, the bag cutting mechanism can cut one end of the packaging bag to form an incision at one end of the packaging bag. When the packaging bag with the incision reaches the ejection mechanism, the second driver is controlled to drive the ejection mechanism to push the material in the packaging bag, thereby ejecting the material from the incision of the packaging bag, thereby achieving automatic unpacking of the material.

[0045] It should be noted that the bag cutting mechanism forms an incision in the packaging bag, which can greatly reduce the resistance the material encounters from the packaging bag when it is pushed out, allowing the material to be smoothly pushed out through 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 pushed out, thereby reducing the deformation of the packaging bag. This, in turn, reduces the risk of the material being unable to be smoothly pushed out due to excessive deformation of the packaging bag, thereby improving the stability and reliability of the equipment operation. Connecting both the conveying mechanism and the bag cutting mechanism to the first driver allows the conveying mechanism and the bag cutting mechanism to operate synchronously. Thus, each time the conveying mechanism delivers a piece of material to the bag cutting mechanism, the bag cutting mechanism 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.

[0046] Therefore, the automatic unpacking machine provided by the present invention can realize efficient and automated material unpacking and pushing-out processes, reduce workload, have higher efficiency, be more hygienic, and have higher stability and reliability.

[0047] The control method provided by the present invention has all the advantages of the automatic unpacking machine mentioned above because it is applied to the automatic unpacking machine mentioned above, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0069] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0070] See also Figure 1-Figure 7 This embodiment provides an automatic packaging machine, which includes a first driver 410, a second driver 420, a conveying mechanism 100, a bag cutting mechanism 200 and a pushing mechanism 300; the bag cutting mechanism 200 and the pushing mechanism 300 are arranged in sequence along the conveying direction of the conveying mechanism 100, and the conveying mechanism 100 and the bag cutting mechanism 200 are both connected to the first driver 410, and the conveying mechanism 100 and the bag cutting mechanism 200 operate synchronously; the pushing mechanism 300 is connected to the second driver 420; the conveying mechanism 100 is used to drive the conveying of materials packaged in the packaging bag, the bag cutting mechanism 200 is used to cut one end of the packaging bag, and the pushing mechanism 100 is used to push the material out of the incision of the packaging bag.

[0071] During use, the material contained in the packaging bag is placed at the input port of the conveying mechanism 100, and the first driver 410 is controlled to start working, driving the conveying mechanism 100 and the bag cutting mechanism 200 to operate synchronously. The conveying mechanism 100 can convey the material along the conveying direction. Under the conveying of the conveying mechanism 100, the material contained in the packaging bag will pass through the bag cutting mechanism 200 and the ejection mechanism 300 in sequence; when the material contained in 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; when the packaging bag with the incision reaches the ejection mechanism 300, the second driver 420 is controlled to drive the ejection mechanism 300 to push the material in the packaging bag, so as to push the material out of the incision of the packaging bag, thereby realizing automatic unpacking of the material.

[0072] It should be noted that the bag cutting mechanism 200 forms an incision on the packaging bag, which can greatly reduce the resistance the material encounters from the packaging bag when being pushed out, allowing the material to be smoothly pushed out from the incision of the packaging bag; at the same time, it can also reduce the force the packaging bag experiences when the material is pushed out, thereby reducing the deformation of the packaging bag, and further reducing the risk of the material being unable to be smoothly pushed out due to excessive deformation of the packaging bag, thereby improving the stability and reliability of the equipment operation. Connecting both the conveying mechanism 100 and the bag cutting mechanism 200 to the first driver 410 can enable the conveying mechanism 100 and the bag cutting mechanism 200 to operate synchronously. Therefore, each time the conveying mechanism 100 conveys a material to the bag cutting mechanism 200, the bag cutting mechanism 200 can complete the cutting of a packaging bag. This not only meets the needs of conveying and bag cutting, but also reduces the number of drivers, reduces costs, and simplifies the control logic.

[0073] Therefore, the automatic unpacking machine provided in this embodiment can realize an efficient and automated material unpacking and pushing process, reduce workload, have higher efficiency, be more hygienic, and have higher stability and reliability.

[0074] There is material in the packaging bags on the incoming material side of the ejection mechanism 300 .

[0075] In the specific structure of the automatic packaging machine provided in this embodiment, a shell 600 can be set. The above-mentioned conveying mechanism 100, bag cutting mechanism 200 and ejection mechanism 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 mechanism 100 and is used for placing materials; the output port is opposite to the output end of the conveying mechanism 100 and is used for outputting discarded empty bags; the outlet port 420 is opposite to the ejection mechanism 300 and is used for outputting materials pushed out of the packaging bag.

[0076] A controller may also be provided in the specific structure of the automatic unpacking machine provided in this embodiment. The controller may be a PLC controller or other controllers.

[0077] Furthermore, a first detection element may be provided to detect whether material has passed through the first detection position, wherein the first detection position is located between the bag cutting mechanism 200 and the ejection mechanism 300. The first detection element and the second driver 420 are both communicatively connected to the controller. When the first detection element detects that material has passed through the first detection position, it indicates that the packaging bag has been cut. At this time, the controller can control the second driver 420 to drive the ejection mechanism 300 according to the corresponding signal sent by the first detection element, so that the ejection mechanism 300 can eject the material at the corresponding position from the incision of the packaging bag, thereby realizing automatic control of the second driver 420 and improving the intelligence level. Preferably, the first detection position is provided adjacent to the ejection mechanism 300 so that the material reaches the corresponding position of the ejection mechanism 300 after passing the first detection position, thereby improving the working efficiency of the ejection mechanism 300.

[0078] Furthermore, a second detection element and an alarm may be provided to detect the presence of material at a second detection position, where the second detection position corresponds to the bag cutting mechanism 200. Both the second detection element and the alarm are communicatively connected to the controller. When the second detection element detects the absence of material at the second detection position, indicating that the material has been depleted, the controller may control the alarm to sound an alarm based on a corresponding signal sent by the second detection element, thereby reminding the user to replenish the material in a timely manner. Specifically, the second detection element may be the first photoelectric switch 520, and the alarm may be a buzzer.

[0079] Furthermore, a third detection element may be provided in the specific structure of the automatic unpacking machine provided in this embodiment to detect whether material is present 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 third detection element and the first driver 410 are both communicatively connected to the controller. When the third detection element detects the presence of material at the outlet 620, it indicates that the unpacked material has not yet been removed. At this time, the controller can control the first driver 410 to stop according to the corresponding signal sent by the third detection element, so that the conveying mechanism 100 no longer conveys the material and the bag cutting mechanism 200 no longer cuts the packaging bag. When the third detection element detects the absence of material at the outlet 620, it indicates that the material has been removed or has not yet been delivered to the outlet 620. At this time, the controller can control the first driver 410 to start according to the corresponding signal sent by the third detection element, so that the conveying mechanism 100 continues to convey the material and the bag cutting mechanism 200 continues to cut the packaging bag. The third detection element may be a second photoelectric switch 530 .

[0080] Furthermore, in the specific structure of the automatic package unpacking machine provided in this embodiment, a fourth detection element and a fifth detection element may be provided. The ejection mechanism 300 includes a push block 310 for pushing the material. When the push block 310 moves from an initial position to an end position, the material is ejected from the incision of the packaging bag. The fourth detection element is capable of detecting whether the push block 310 has reached the end position, and the fifth detection element is capable of detecting whether the push block 310 has reached the initial position. The fourth detection element, the fifth detection element, and the second driver 420 are all communicatively connected to a controller. When the fourth detection element detects that the push block 310 has reached the end position, indicating that the material has been ejected, the controller can control the second driver 420 to stop and then reverse direction based on a signal from the fourth detection element, thereby driving the push block 310 of the ejection mechanism 300 to move in the opposite direction toward the initial position. When the fifth detection element detects that the push block 310 has reached the initial position, indicating that the ejection mechanism 300 has reset, the controller can control the second driver 420 to stop based on a signal from the fifth detection element, so that the ejection mechanism 300 maintains its current state to facilitate ejection of the next material. Specifically, the fourth detection element may be a proximity switch 540 , and the fifth detection element may be a third photoelectric switch 550 .

[0081] The first photoelectric switch 520 , the second photoelectric switch 530 , the third photoelectric switch 550 and the proximity switch 540 may all be mounted on the housing 600 .

[0082] The specific structure of the automatic packaging machine provided in this embodiment may also be provided with a transmission assembly. The specific structure of the conveying mechanism 100 may include several roller groups spaced apart along the conveying direction. The roller groups may specifically include several pairs of driving wheels 110 and driven wheels 120 that roll together. The gaps between the driving wheels 110 and the driven wheels 120 allow material to pass through. The driving wheels 110 in the same roller group are arranged coaxially. The first driver 410 is connected to each driving wheel 110 via the transmission assembly so that the first driver 410 can drive each driving wheel 110 to rotate synchronously through the transmission assembly. The rotation of the driving wheels 110 can convey the material forward. The presence of the driven wheels 120 prevents the packaging bags from slipping, thereby improving conveying reliability. The first driver 410 may be a first motor.

[0083] For long strips of material (e.g., cotton swabs), the conveying direction of the conveying mechanism 100 is set perpendicular to the length of the material. This helps improve the efficiency of material conveying and increases the compactness of the structure. With a smaller size, it can be configured as a small desktop structure, ensuring that the machine is compact 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 encapsulated 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.

[0084] In the specific structure of the conveying mechanism 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 ejection mechanism 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 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 widened, 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 fall back to smoothly press the flat packaging bag, thereby ensuring the conveying effect.

[0085] A torsion spring can also be provided 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 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 material in the packaging 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 stability.

[0086] The roller pair may include a first roller pair 160 located between the bag cutting mechanism 200 and the ejection mechanism 300. A microswitch 510 may be mounted on the housing 600. The microswitch 510 is triggered when the driven wheel 120 in the first roller pair 160 is lifted by the material. The microswitch 510 and the second driver 420 are both communicatively connected to a controller. When the microswitch 510 is triggered, the controller controls the second driver 420 to drive the ejection mechanism 300 to eject the material from the incision of the packaging bag, thereby automatically activating the second driver 420 and improving the level of intelligence. The microswitch 510 may serve as the first detection element.

[0087] 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 mechanism 200, the first roller pair 160, the ejection mechanism 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 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 cutting the packaging bag; similarly, the first roller pair 160 and the third roller pair 180 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 push the material in the packaging bag out.

[0088] 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 transmission assembly 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 packaging 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 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 conveying of the material, allowing the material to be smoothly conveyed by the conveying mechanism 100.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 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, thereby driving the conveying mechanism 100. The second driven gear 730 is coaxially fixedly connected to the hob 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 hob 210 to rotate, thereby cutting the packaging bag. Specifically, the size of the first driven gear 720 can be adjusted according to the required linear speed of each roller pair to ensure the stability and accuracy of the material during transportation; the size of the second driven gear 730 can be adjusted according to the required rotation speed of the hob 210.

[0093] The bag cutting mechanism 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.

[0094] In addition, two limiters 800 can be provided in the specific structure of the automatic unpacking machine. 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.

[0095] 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.

[0096] The push mechanism 300 may include 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 both arranged to be parallel to the length of the elongated material. A second driver 420 is connected to the lead screw 320 to drive the lead screw 320 to rotate. The lead screw 320 is mated with the nut 330, and the guide rail 340 is slidably connected to the nut 330. A push block 310 for pushing the material out is fixed to the nut 330. Rotation of the lead screw 320 drives the nut 330 to move along the guide rail 340, and the push block 310 pushes the material out along its length. The second driver 420 may be a second motor.

[0097] Furthermore, the ejection mechanism 300 may further include a guide structure to guide the ejected material to the outlet 620 , thereby facilitating smooth exit of the material.

[0098] 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 to rotatably connect the flip cover 900 to the housing 600, and the flip cover 900 is connected 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 materials.

[0099] The automatic unpacking machine provided in this embodiment can place multiple materials packaged in packaging bags at one time and automatically peel them out one by one. The user only needs to take away the materials, and the machine can automatically remove the discarded empty bags and prepare for the next operation.

[0100] Before the machine is operated, the operator neatly places a row of materials individually packaged in packaging bags into the input port of the conveying mechanism 100, turns on the power, presses the start button, and the machine starts to work automatically; the conveying mechanism 100 inside the machine will convey the materials packaged in the packaging bags one by one to the bag cutting mechanism 200, and after cutting, they will continue to be conveyed to the ejection mechanism 300; the ejection mechanism 300 will push the single material to the outlet 620, waiting for the staff to take it. The machine is equipped with an automatic sensing system (third detection element) that can detect the material's exit status in real time. Once it senses that the material has been taken away, it will immediately prepare to push out the next material. In addition, the machine also has an inventory detection function (second detection element). When the internal material is exhausted, a buzzer will sound a prompt to remind the operator to replenish the material in time.
