Description

[0001] This invention is a divisional application of "Automatic Packaging Machine and Method for Gauze Sheets" (Application No.: 2022106537024; Application Date: June 10, 2022). Technical Field

[0002] This invention belongs to the field of gauze sheet packaging technology, and specifically relates to an automated packaging method for gauze sheets. Background Technology

[0003] Gauze pads are widely used in the medical field. Currently, gauze pad packaging is mainly achieved manually, lacking an automated bagging and packaging system. Chinese patent document CN 207595390 U discloses "a paper bag packaging machine for packaging medical gauze," but this patented technology can only push a stack of gauze pads, but cannot realize the automatic feeding, compression, bagging, and sealing of the gauze pads. Therefore, at present, there is a lack of a packaging machine specifically for packaging gauze pads. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the automated packaging method for gauze sheets provided by the present invention realizes continuous packaging of gauze sheets, and realizes a series of packaging processes such as automatic feeding, compression, bagging, and sealing, thereby improving the efficiency of gauze sheet packaging.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automated packaging method for gauze sheets utilizes an automatic gauze sheet packaging machine. The automatic gauze sheet packaging machine includes a gauze sheet feeding and conveying device, a compression filling device, a packaging bag feeding device, and a packaging bag folding and sealing device. The packaging process is as follows:

[0007] Gauze sheet feeding process:

[0008] S1.1: The gauze sheet feeding and conveying device continuously feeds the compressing packing device;

[0009] S1.2: When the feeding trough in the gauze sheet feeding and conveying device runs to the gauze compression device, the gauze sheet in the feeding trough is compressed by the gauze compression device.

[0010] S1.3: When the feeding trough reaches the first-level pushing device, the first-level pushing device is activated to push the gauze sheet in the feeding trough into the moving trough.

[0011] S1.4: The moving trough drive device drives the moving trough to move towards one end of the packaging bag feeding device;

[0012] During the gauze sheet feeding process, the packaging bag feeding is carried out simultaneously. The packaging bag feeding process is as follows:

[0013] S2.1: Place the packaging bag into the upward feeding trough;

[0014] S2.2: The suction cup extraction mechanism of the packaging bag feeding robot moves, and the suction cup extraction mechanism pulls the packaging bag outward from the extraction port, and the lower end of the packaging bag is pulled to the outside of the extraction port;

[0015] S2.3: The moving clamp action: the moving clamp grips the bottom of the packaging bag and moves it diagonally downward, and the packaging bag is pulled out as a whole; when the moving clamp moves down to the bottom, the packaging bag is flipped over by its own gravity and placed flat on the packaging bag support.

[0016] S2.4: The movable clamp resets, and the packaging bag extraction process ends. The packaging bag pushing mechanism pushes other packaging bags toward the extraction port.

[0017] S2.5: The single-sided lifting mechanism operates by sucking up and lifting the top surface of the packaging paper bag. The bottom surface of the packaging paper bag separates from the top surface under its own weight, and the opening of the packaging paper bag opens.

[0018] S2.6: The opening mechanism operates, driving the two insert plates to move towards one end of the packaging bag opening. When the two insert plates are inserted into the packaging bag opening, the two insert plates open relative to each other, opening the packaging bag opening.

[0019] S2.7: The lateral translation mechanism moves, causing the opening mechanism and the packaging bag to move together;

[0020] S2.8: When the opening mechanism moves to the pre-support device, the pre-support device activates and fully opens the packaging bag;

[0021] S2.9: Once the feeding action for a single packaging bag is completed, repeat S2.1-S2.8 to achieve continuous feeding;

[0022] When the gauze sheet feeding and packaging bag feeding are completed simultaneously, the gauze sheet to be bagged is positioned opposite the packaging bag. The secondary pushing device is activated to push the gauze sheet into the packaging bag, and the gauze sheet bagging process is completed.

[0023] Then proceed with the folding and sealing process of the packaging bag:

[0024] S3.1: The slanted fork telescopic mechanism operates, causing the slanted fork to be inserted at an angle into the inside of the packaging bag opening. The slanted fork is located on the first fold line. The baffle anti-detachment mechanism operates, causing the baffle to extend into the packaging bag. The baffle is used to prevent the material inside the packaging bag from falling out.

[0025] S3.2: The clamp lifting and rotating mechanism operates. The lifting mechanism in the clamp lifting and rotating mechanism drives the double clamping fixture to move upward. During the upward movement of the double clamping fixture, the packaging bag is folded. The double clamping fixture and the slanted fork cooperate to complete the first fold of the opening of the packaging bag.

[0026] S3.3: The baffle anti-detachment mechanism resets, and the baffle retracts;

[0027] S3.4: The diagonal fork telescopic mechanism resets, and the diagonal fork retracts;

[0028] S3.5: The double-clamp clamp action clamps the first fold of the packaging bag;

[0029] S3.6: The rotating mechanism in the clamp lifting and rotating mechanism operates. The clamps in the double clamp clamp have a triangular structure. The hypotenuse of the triangle is the reference side for the second fold. The double clamp clamp drives the packaging bag to be folded for the second time.

[0030] S3.7: The positioning plate mechanism operates, and the positioning plate of the positioning plate mechanism presses down the packaging bag after the second fold.

[0031] S3.8: The clamping plate lifting and rotating mechanism resets, the double clamping clamps descend and detach from the packaging bag, and the clamping plate lifting and rotating mechanism returns to the state in step S3.1;

[0032] S3.9: The folding plate mechanism operates by rotating the folding plate, which causes the protruding part of the packaging bag to fold during the second fold, thus completing the third fold of the packaging bag; the side of the positioning plate of the positioning plate mechanism serves as the reference edge for the third fold.

[0033] S3.10: The folding mechanism resets, and the opening end of the packaging bag is folded.

[0034] S3.11: Use a labeling machine or adhesive applicator to seal the package and complete the packaging.

Detailed Implementation

[0089] An automated packaging method for gauze sheets utilizes an automatic gauze sheet packaging machine, such as... Figures 1 to 39 As shown, the automatic gauze sheet packaging machine mainly consists of four parts: a gauze sheet feeding and conveying device 1, a compression filling device 2, a packaging bag feeding device 3, and a packaging bag folding and sealing device 4. The specific structure is as follows:

[0090] The gauze sheet feeding and conveying device 1 in this technical solution includes a feeding trough 101, which is installed on a conveyor chain drive mechanism 102 or a transmission belt drive mechanism. A movable baffle 104 is provided in the feeding trough 101, and the movable baffle 104 is connected to an elastic element. One end of the feeding trough 101 is provided with a discharge port, and the other end of the feeding trough 101 is provided with a compression plate inlet. A side baffle 103 is provided on one side of the discharge port, and the side baffle 103 is attached to the discharge port. The space between the side baffle 103 and the movable baffle 104 is used to place the gauze sheet.

[0091] like Figure 2 As shown, in this embodiment, there are multiple feeding troughs 101, which are installed parallel to each other on the conveyor chain drive mechanism 102. The conveyor chain drive mechanism 102 is used to drive the feeding troughs 101. The feeding troughs 101 are used to hold gauze sheets that need to be bagged and packaged. Since a compression device and a filling device need to be set at the downstream end of the process of this device, the two ends of the feeding troughs 101 need to be designed as open structures, that is, the two ends of the feeding troughs 101 are the discharge port and the compression plate inlet. In order to ensure that the gauze sheets do not tip over in the feeding troughs 101, a side baffle 103 is provided on the side of the discharge port. The side baffle 103 does not move with the feeding troughs 101 and extends all the way to the filling device. When the feeding troughs 101 run to the filling device, the filling device pushes the gauze sheets in the feeding troughs 101 into the packaging bag.

[0092] In this embodiment, the gauze sheets in the feeding trough 101 can be fed manually or by a robotic arm.

[0093] This technical solution designs a movable baffle 104, the purpose of which is:

[0094] 1. Place a stack of gauze sheets between the movable baffle 104 and the side baffle 103. The movable baffle 104 is subjected to the action of the elastic element, which can play a redundant adjustment role.

[0095] 2. A stack or row of gauze sheets in the feeding trough 101 will be squeezed by the compression plate of the compression device, and its length will be compressed by more than half. The movable baffle 104 is subject to the action of the elastic element and can be adaptively adjusted according to the length of the stack of gauze sheets to ensure the stability of the gauze sheets.

[0096] The elastic element is a cylindrical spring 107. In this embodiment, the specific installation structure of the movable baffle 104 and the cylindrical spring is as follows:

[0097] A partition 105 is provided inside the feeding trough 101, dividing the feeding trough 101 into upper and lower layers. An elastic element is located between the partition 105 and the feeding trough 101. A strip-shaped groove 106 is provided on the partition 105, and a movable baffle 104 is located in the strip-shaped groove 106. One end of the cylindrical spring is welded and fixed to the movable baffle 104, and the other end is welded and fixed to the feeding trough 101.

[0098] The compression filling device 2 in this technical solution includes a gauze compression device 201 disposed on the side of the discharge trough 101. The gauze compression device 201 is used to compress the gauze sheets in the discharge trough 101. A primary pushing device 202 is provided at the rear end of the gauze compression device 201. The primary pushing device 202 is used to push the compressed gauze sheets into the moving trough 204. A secondary pushing device 203 is provided above the moving trough 204. The secondary pushing device 203 is used to push the gauze sheets on the moving trough 204 into the packaging bag. The secondary pushing device 203 is driven to move up and down by a lifting cylinder 205; the moving trough 204 is driven to move horizontally by a moving trough driving device 206. A lifting plate mechanism 207 is provided at the front end of the moving trough 204. The lifting plate mechanism 207 is provided with a liftable plate, which is used to prevent the gauze sheets from falling.

[0099] The gauze compression device 201, the primary pushing device 202, the secondary pushing device 203, the moving trough drive device 206, and the lifting plate mechanism 207 mentioned in this technical solution can all be cylinders or electric push rods. Specifically, in this embodiment, the gauze compression device 201 includes a compression cylinder, and the movable end of the compression cylinder is provided with a pressure plate, which is used to compress the gauze sheet in the feeding trough 101; the primary pushing device 202 includes a cylinder and a push plate; the secondary pushing device 203 includes a cylinder and a push plate;

[0100] The lifting cylinder 205 includes a cylinder, which is used to drive the secondary pushing device 203 to move up and down; the moving trough 204 is driven to move horizontally by the moving trough driving device 206.

[0101] like Figure 7 As shown, the moving tank drive device 206 includes a cylinder, the telescopic end of which is used to drive the moving tank 204 to move. Figure 7-8 This is a structural diagram used to illustrate the two-stage pushing process. The moving slot drive device 206 can be set on the upper, lower or side of the moving slot 204. To facilitate the display of the working principle of the moving slot drive device 206, the moving slot drive device 206 is drawn below the moving slot 204.

[0102] As a preferred embodiment, the front end of the movable slot 204 is provided with a lifting plate mechanism 207, which is equipped with a liftable plate to prevent the gauze sheet from falling off.

[0103] The working principle is as follows:

[0104] The gauze compression device 201 is used to compress and compact the gauze sheets in the feeding trough 101 so that the length of a row of gauze sheets meets the bagging length, and on the other hand, it can prevent the gauze sheets from tipping over.

[0105] The primary feeding device 202 is used to push the gauze sheet in the feeding trough 101 into the moving trough 204, so that the empty feeding trough 101 can be circulated for feeding.

[0106] Since this device needs to fill the packaging bag, and the packaging bag is continuously fed by the packaging bag feeding device, a movable trough 204 is designed. The movable trough 204 is used to actively insert into the packaging bag 5.

[0107] The secondary pushing device 203 is used to push the gauze sheet in the moving trough 204 into the packaging bag 5.

[0108] The packaging bag feeding device 3 in this technical solution includes a feeding trough 301, which is used to place packaging bags. The end of the feeding trough 301 is provided with a extraction port 302. A packaging bag feeding robot 303 is provided at the extraction port 302. The packaging bag feeding robot 303 is used to transfer the packaging bags to the packaging bag support 304. A single-sided lifting mechanism 305 is provided above the packaging bag support 304. The single-sided lifting mechanism 305 cooperates with the opening mechanism 306. The opening mechanism 306 is used to open the opening of the packaging bag.

[0109] The packaging bag in this technical solution is a paper bag, which is folded into a flat shape. When the paper bag is opened, it has a square column structure, and its cross-sectional shape matches the shape of the gauze sheet. Existing gauze sheets are generally square sheets. The extraction port 302 is located in the lower half of the side of the feeding trough 301. When the packaging bag feeding robot 303 picks up the paper bag and places it on the packaging bag support 304, the single-sided lifting mechanism 305 above the packaging bag support 304 is activated. The single-sided lifting mechanism 305 uses a suction cup mechanism to suck up and lift the top surface of the paper bag. The bottom surface of the paper bag separates from the top surface under its own weight, and the opening of the paper bag is slightly opened. The opening mechanism 306 opens the opening of the paper bag, and the filling device of the automatic gauze sheet packaging machine is activated to push a stack of gauze sheets into the paper bag. The subsequent sealing device seals the paper bag.

[0110] Furthermore, the packaging bag loading robot 303 includes a suction cup extraction mechanism 303.1 and a movable clamp 303.2; the suction cup extraction mechanism 303.1 includes a suction cup, which is driven to move by a cylinder, and is used to extract the packaging bag from the extraction port 302; the movable clamp 303.2 includes a clamp, which is driven to move by a cylinder or chain mechanism, and is used to clamp the packaging bag and transfer it to the packaging bag support 304.

[0111] In this embodiment, the packaging bag in the feeding trough 301 is placed vertically. The suction cup extraction mechanism 303.1 is used to suck up the lower part of the packaging bag and pull it out a certain distance, so that the lower edge of the packaging bag is detached from the feeding trough 301. The movable clamp 303.2 clamps the lower edge of the packaging bag and moves it diagonally downward. During the diagonal downward movement of the movable clamp 303.2, the packaging bag is also rotated by its own weight. The packaging bag support 304 is set directly below the feeding trough 301. After the movable clamp 303.2 moves into position, the packaging bag is placed flat on the packaging bag support 304. The movable clamp 303.2 includes a pneumatic clamp and a clamp traction mechanism. The clamp traction mechanism can be an electric push rod or a chain drive. As a preferred embodiment, the packaging bag support 304 is equipped with a belt conveyor, which is used to finely adjust the position of the packaging bag back and forth.

[0112] Furthermore, the single-sided lifting mechanism 305 includes a suction cup that is driven to move by a cylinder. The single-sided lifting mechanism 305 is used to suction the top surface of the packaging bag and lift the packaging bag upwards.

[0113] The packaging bag is placed flat on the packaging bag support 304. The top surface refers to the side of the packaging bag facing upwards, and the bottom surface refers to the side of the packaging bag facing downwards. When the single-sided lifting mechanism 305 lifts the packaging bag, the bottom surface of the packaging bag naturally droops down, and the opening of the packaging bag slightly opens.

[0114] Furthermore, the opening mechanism 306 includes two insert plates 306.1, which are driven to move by a cylinder assembly. The two insert plates 306.1 are used to insert into the opening of the packaging bag and open the opening of the packaging bag.

[0115] The function of the cylinder assembly is to drive the two insert plates 306.1 to move towards the opening of the packaging bag. When the two insert plates 306.1 are inserted into the opening of the packaging bag, they open relative to each other, thus opening the packaging bag. In this embodiment, the two insert plates 306.1 are symmetrically arranged vertically. When the two insert plates 306.1 are inserted into the opening of the packaging bag, the lower insert plate 306.1 moves downward. The cylinder assembly includes a horizontally driven cylinder and a vertically driven cylinder. The insert plate 306.1 has an L-shaped thin sheet structure, preferably made of stainless steel. Alternatively, the two insert plates 306.1 can be symmetrically arranged horizontally.

[0116] Furthermore, the opening mechanism 306 is driven to reciprocate by the transverse translation mechanism 308.

[0117] The lateral translation mechanism 308 drives the opening mechanism 306 to move as a whole. In the automatic gauze sheet packaging machine, the filling device at the rear end of the packaging bag feeding device is used to push a stack of gauze sheets into the packaging paper. Therefore, when the two insert plates 306.1 are inserted into the opening of the packaging bag, the lateral translation mechanism 308 moves the opening mechanism 306 together with the packaging bag to the filling device, so that the opening of the packaging bag is in a straight line with the stack of gauze sheets. During the filling process, the two insert plates 306.1 are always inserted into the opening of the packaging bag.

[0118] The lateral translation mechanism 308 in this technical solution can be an electric push rod, a cylinder, a lead screw drive mechanism, or a gear and rack drive mechanism, such as... Figure 16 As shown, the lateral translation mechanism 308 is replaced by a block diagram, and its structure can adopt the parallel movement drive mechanism in the prior art.

[0119] Appendix Figure 9 The distance between the opening mechanism 306 shown and the packaging bag is relatively short. This diagram conforms to the design spacing of the actual product. Figure 16 The relatively long distance between the opening mechanism 306 and the packaging bag is a schematic diagram drawn to illustrate their working principle.

[0120] Furthermore, the cylinder for driving the insert plate 306.1 is assembled on the moving frame 306.2, and the moving frame 306.2 is provided with a packing gap or a packing channel.

[0121] During the filling process, the two insert plates 306.1 are always inserted at the opening of the packaging bag, and the gauze sheet passes through the filling gap or filling channel. The filling device in the automatic gauze sheet packaging machine is equipped with a telescopic filling groove, which can pass through the filling gap or filling channel.

[0122] Furthermore, the movable frame 306.2 is provided with two packing channels, and each of the two packing channels is provided with two insert plates 306.1 and a cylinder assembly for driving the insert plates 306.1.

[0123] As a preferred embodiment, before filling the packaging bag with filler, the pre-support device 309 is used to fully open the packaging bag to facilitate subsequent filling operations. In this embodiment, the packaging bag is a paper bag. The purchased paper bag is folded, and the tail of the paper bag lifted by the single-sided lifting mechanism 305 is not fully open. After being adjusted by the pre-support device 309, the paper bag will have a rectangular cylindrical structure.

[0124] Furthermore, the lateral translation mechanism 308 is used to move the packaging bag toward the pre-support device 309, which includes a support plate 309.1, which is driven to move by a cylinder.

[0125] The support plate 309.1 is used to move back and forth once inside the packaging paper bag, and the outer contour of the support plate 309.1 is adapted to the cross-section of the packaging paper bag.

[0126] Furthermore, the feeding trough 301 is provided with a packaging bag pushing mechanism 307, which is used to push the packaging bag toward the extraction port 302.

[0127] The packaging bag pushing mechanism 307 includes a push plate, which is driven by a cylinder or connected to an elastic element to keep the packaging bag always attached to the extraction port 302.

[0128] The packaging bag folding and sealing device 4 in this technical solution includes a slanted fork telescopic mechanism 401, a clamping plate lifting and rotating mechanism 402, and a folding plate mechanism 403. The slanted fork telescopic mechanism 401 includes an inclined fork 401.1, which is driven to move by a driving mechanism. The clamping plate lifting and rotating mechanism 402 includes two sets of double clamping plates 402.1, each set of double clamping plates 402.1 being driven by both the lifting mechanism and the rotating mechanism. The double clamping plates 402.1 cooperate with the slanted fork 401.1. The folding plate mechanism 403 includes a flip-up folding plate.

[0129] In this embodiment, the packaging bag 5 is a paper bag, which unfolds into a cuboid shape. The paper bag contains gauze sheets, and the opening needs to be sealed after the gauze sheets are placed inside. This invention utilizes the cooperation of a fork telescopic mechanism 401, a clamping plate lifting and rotating mechanism 402, and a folding plate mechanism 403 to achieve multiple folds of the paper bag. The folding plate mechanism 403 is used to achieve the third fold of the packaging bag. The folding plate is driven to rotate by a rotary motor, and each rotation angle is 180°. The preceding process of this packaging bag folding and sealing device is a filling process. After the packaging bag is filled by the filling device, it is transferred by a robotic gripper to the working area of ​​this packaging bag folding and sealing device, such as... Figure 23 As shown, the packaging paper bag is held by the robotic arm gripper 6.

[0130] Furthermore, the slanted fork 401.1 includes two parallel rods, the diameter of which is smaller than the maximum movable clearance of the double-clamp clamp 402.1; the slanted fork 401.1 is used to be inserted obliquely into the inside of the packaging bag, and the double-clamp clamp 402.1 is driven upward by a lifting mechanism to move upward. The double-clamp clamp 402.1 and the slanted fork 401.1 cooperate to perform the first fold of the opening of the packaging bag; the slanted fork 401.1 is used to provide a reference edge for the first fold.

[0131] As the double clamp 402.1 moves upward, it causes the packaging paper bag to fold. Since the diagonal fork 401.1 provides a folding reference edge, the packaging paper bag will be folded for the first time along the straight line where the diagonal fork 401.1 is located.

[0132] Furthermore, it also includes a baffle anti-detachment mechanism 404, which includes a baffle that is driven to move by a cylinder.

[0133] The baffle is used to separate the gauze pieces and prevent them from falling out of the packaging paper bag. The baffle of the anti-detachment mechanism 404 can be retracted after the packaging paper bag is folded for the first time. The baffle anti-detachment mechanism 404 is the preferred solution; its purpose is to prevent the gauze pieces from tipping over. If the gauze filling is relatively dense, the baffle anti-detachment mechanism 404 can be omitted.

[0134] Furthermore, the double-clamp clamp 402.1 is an electric clamp or a pneumatic clamp. After the slanted fork 401.1 is retracted, the double-clamp clamp 402.1 is used to clamp the packaging bag and drive the packaging bag to be folded a second time through the rotating mechanism.

[0135] The double-clamp clamp 402.1 in this invention is an electric or pneumatic clamp with adjustable gap. The two clamps in the double-clamp clamp 402.1 are used to clamp the packaging paper bag and flip the packaging paper bag.

[0136] Furthermore, the tops of the two clips of the double clip fixture 402.1 are triangular in shape, with the hypotenuse of the triangle serving as the reference edge for the second fold.

[0137] The double-clamp clamp 402.1 is an important functional component of this invention. The lifting and rotating functions of the double-clamp clamp 402.1 can be accomplished by existing robotic arms, and the clamping function of the double-clamp clamp 402.1 is the same as that of existing electric or pneumatic clamps. The difference of the double-clamp clamp 402.1 is that the clamping component is a triangular clamping structure, and the hypotenuse of the triangle is designed according to the size of the packaging paper bag.

[0138] Furthermore, it also includes a positioning plate mechanism 405, which is equipped with a movable positioning plate. The positioning plate is arranged opposite to the clamping plate lifting and rotating mechanism 402. The positioning plate is used to cooperate with the folding plate mechanism 403 to fold the packaging bag for the third time.

[0139] The width of the positioning plate is determined by the width of the packaging bag. The functions of the positioning plate are: first, to hold down the first two folds; second, to provide a reference edge for the third fold.

[0140] Furthermore, the positioning plate of the positioning plate mechanism 405 is driven by both a vertical drive cylinder and a horizontal drive cylinder.

[0141] The positioning plate mechanism 405 can be mounted on the robotic gripper 6 and move together with the robotic gripper 6. The folding plate mechanism 403 in this invention can be set separately next to the slanted fork telescopic mechanism 401. After the first two folds are completed, the robotic gripper 6 moves the packaging bag to the working area of ​​the folding plate mechanism 403. The folding plate mechanism 403 completes the third fold and the positioning plate mechanism 405 is reset.

[0142] Preferably, a partition feeding device can be added next to the gauze compression device, including a partition feeding trough, a pusher plate inside the partition feeding trough, the pusher plate being driven to move by a pushing device, the pushing device being used to push the partition plate inside the partition feeding trough to move; the outlet of the partition feeding trough is equipped with a suction cup mechanism, the suction cup mechanism being used to pick up the partition plate, the suction cup mechanism being driven to move by a lateral translation mechanism. The partition feeding trough is located next to the gauze compression device, the driving direction of the pushing device is consistent with the driving direction of the gauze compression device, and the driving direction of the lateral translation mechanism is perpendicular to the driving direction of the pushing device; the lateral translation mechanism is used to be located at the junction of the gauze compression device and the feeding trough.

[0143] In this embodiment, the pushing device includes a motor that drives a lead screw to rotate. The lead screw is threadedly engaged with an internally threaded cylinder, which is connected to a push plate via a slide rod. A strip-shaped slot is provided at the bottom of the feed trough on the partition plate, through which the slide rod passes. The lead screw is located below the feed trough on the partition plate. The pushing device can be replaced by a pneumatic cylinder or a hydraulic cylinder. The motor is a servo motor that drives the lead screw to rotate. The lead screw is threadedly engaged with the internally threaded cylinder, and the translation of the internally threaded cylinder causes the push plate to translate, which in turn causes the partition plate to move.

[0144] The pushing device can be replaced by other propulsion mechanisms, such as cylinders, hydraulic cylinders, or electric push rods.

[0145] Furthermore, the lateral translation mechanism is a first cylinder, the telescopic end of which is connected to the suction cup mechanism. After the suction cup mechanism picks up a partition, the lateral translation mechanism actuates, moving the partition between the gauze compression device and the feeding trough. The feeding trough contains gauze sheets to be compressed. While compressing the gauze sheets, the partition is pushed into the feeding trough along with them. Based on existing technology, a rigid partition is set at the end of each stack of gauze sheets to be packaged. The gauze compression device pushes the gauze sheets and the partition together. When the sealing device is used for sealing, the partition plays a shaping role, and the final product is less likely to have rounded corners at the sealing position, and the gauze sheets are less likely to deform, thus ensuring product quality.

[0146] Furthermore, the lateral translation mechanism is driven by a second cylinder, and the driving direction of the second cylinder is consistent with the driving direction of the pushing device. The function of the second cylinder is to drive the suction cup mechanism to actively pick up the partition.

[0152] S1.4: The moving trough drive device drives the moving trough to move towards one end of the packaging bag feeding device;

[0153] During the gauze sheet feeding process, the packaging bag feeding is carried out simultaneously. The packaging bag feeding process is as follows:

[0155] S2.2: The suction cup extraction mechanism of the packaging bag feeding robot moves, and the suction cup extraction mechanism pulls the packaging bag outward from the extraction port, and the lower end of the packaging bag is pulled to the outside of the extraction port;

[0158] S2.5: The single-sided lifting mechanism operates by sucking up and lifting the top surface of the packaging paper bag. The bottom surface of the packaging paper bag separates from the top surface under its own weight, and the opening of the packaging paper bag opens.

[0159] S2.6: The opening mechanism operates, driving the two insert plates to move towards one end of the packaging bag opening. When the two insert plates are inserted into the packaging bag opening, the two insert plates open relative to each other, opening the packaging bag opening.

[0160] S2.7: The lateral translation mechanism moves, causing the opening mechanism and the packaging bag to move together;

[0161] S2.8: When the opening mechanism moves to the pre-support device, the pre-support device activates and fully opens the packaging bag;

[0162] S2.9: Once the feeding action for a single packaging bag is completed, repeat S2.1-S2.8 to achieve continuous feeding;

[0163] When the gauze sheet feeding and packaging bag feeding are completed simultaneously, the gauze sheet to be bagged is positioned opposite the packaging bag.

The baffle is used to prevent the material inside the packaging bag from falling out.

[0166] S3.2: The clamp lifting and rotating mechanism operates. The lifting mechanism in the clamp lifting and rotating mechanism drives the double clamping fixture to move upward. During the upward movement of the double clamping fixture, the packaging bag is folded.
