Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a fully automatic facial mask packaging machine. Background Technology

[0002] Currently, the production of face masks on the market generally includes the following steps: First, a special bag-making machine is needed to pre-make multiple stacks of face mask bags. Then, a face mask folding machine is used to fold the face mask fabric and put it into the pre-made face mask bags. Then, these face mask bags containing face mask fabric are transported to the next stage for filling with essence, sealing, coding, and boxing, thus obtaining the boxed face masks commonly seen on the market. However, when consumers buy face masks, they sometimes encounter empty mask bags without the mask sheet packaging. Manufacturers rack their brains and try every possible method to prevent the production of empty bags. But no matter how they control it, empty bags will still be found during the final inspection after filling and sealing. The probability is generally around 0.03%. The probability seems very small, but for manufacturers that produce millions or tens of millions of face masks every day, hundreds or thousands of empty bags will be generated in the finished product. If such a large number of face masks are inspected manually, it would require a huge amount of work. If they are not inspected, then so many empty bags will flow to consumers, which will not only harm the interests of consumers, but also affect the reputation of manufacturers.

[0003] Therefore, eliminating empty bags in the production process is very urgent. Our analysis shows that empty mask bags without mask sheets cannot be generated during the filling and sealing or bag-making stages. Therefore, they must be generated during the folding and bagging of the mask sheet. Further research and observation revealed that empty bags are generated in this process due to the following two situations:

[0004] 1. During the bag-making process, static electricity exists on the mask bags. Since mask bags are usually stacked in groups of 100 or 200, static electricity attracts adjacent mask bags, and this static electricity is difficult to eliminate. When the mask sheet is folded and bagged later, the folding machine needs to pick up and open the bags to complete the bagging. When two adjacent bags in the stack are attracted together by static electricity, the folding machine may pick up both mask bags together. However, only one mask sheet can be bagged at a time, so there will definitely be one mask bag that cannot contain a mask sheet, resulting in an empty bag.

[0005] 2. Some bag-making machines produce bags with right angles instead of rounded corners. When rounded corners are needed, a rounded corner cutting machine is required in another process. During the rounded corner cutting, stacks of mask bags are cut at the same time. After the cutter cuts, one rounded corner of a stack of mask bags is cut. However, during the cutting process, it is inevitable that adhesive will be generated between adjacent mask bags at the cut points. Four rounded corners will result in four adhesives. The adhesive is much stronger than the force of electrostatic attraction that holds two adjacent mask bags together, making it even more difficult to separate the two mask bags. Naturally, when the folding machine picks up the bags, it will also pick up at least two or more mask bags at the same time, inevitably resulting in empty bags.

[0006] As mentioned above, the two situations described are the reasons for empty bags. Empty bags are a common problem in the production of face masks, resulting in some boxed face masks failing to meet quality standards. This not only reduces production quality but also provides consumers with a poor user experience.

[0007] Therefore, there is an urgent need to provide a fully automatic facial mask packaging machine that can eliminate empty bags and produce high-quality products. Summary of the Invention

[0008] To address the shortcomings of the prior art, this invention provides a fully automatic facial mask packaging machine, comprising a folding device, a bag-making device, and a bag-feeding device. The folding device includes a folding mechanism, which comprises a folding support, a facial mask fabric conveyor belt mounted on the folding support, and a facial mask fabric folding assembly for folding the facial mask fabric to be folded conveyed from the conveyor belt. The facial mask fabric folding assembly is located at the end of the conveyor belt and includes a movable first folding blade, a first fold forming device connected to the first folding blade, a movable second folding blade perpendicular to the first folding blade, and a second folding device connected to the second folding blade. The device includes a forming unit, a movable three-fold blade perpendicular to the two-fold blade, and a movable film-filling plate that accommodates the three-fold blade. A one-fold forming unit and a two-fold forming unit are fixedly connected to a folding bracket. A bag-making device is connected to the film-filling plate. The bag-making device includes a main support, a side-sealing mechanism mounted on the main support for side-sealing the film to be packaged, and a cutting mechanism mounted on the main support for cutting the film to be packaged into individual face mask bags. The side-sealing mechanism forms the two sides of the face mask bag adjacent to the opening of the face mask bag by side-sealing the film to be packaged. A bag-feeding device is mounted on the main support to provide power for the movement of the film to be packaged and the face mask bags.

[0009] Furthermore, the bag-making device also includes a bottom sealing mechanism mounted on the main support for sealing the bottom of the packaging bag film. The bottom sealing mechanism forms the bottom edge of the packaging bag film opposite to the opening of the mask bag. The packaging bag film is first sealed at the bottom by the bottom sealing mechanism and then sealed at the side by the side sealing mechanism.

[0010] Furthermore, the bag-making device also includes an opening mechanism mounted on the folding bracket for opening the film to be packaged. The opening mechanism is located before the side sealing mechanism. The opening mechanism includes a front support rod, a rear support rod, and a side guide plate. The front support rod is inserted into the lower middle part of the film to be packaged to open the film. The rear support rod and the side guide plate are used to maintain the shape of the film to be packaged by the front support rod.

[0011] Furthermore, the folding device also includes a folding mechanism adjustment assembly, which includes a folding mechanism slide rail and a folding mechanism adjustment screw mounted on the main support, a folding mechanism slider and a folding mechanism adjustment nut mounted on the folding support. The folding mechanism adjustment screw is rotatably connected to the main support, and a folding mechanism adjustment handwheel is fixedly mounted at one end of the folding mechanism adjustment screw. The folding mechanism slider is slidably connected to the folding mechanism slide rail, and the folding mechanism adjustment nut is sleeved on the folding mechanism adjustment screw. The front and rear positions of the folding mechanism are adjusted by rotating the folding mechanism adjustment handwheel.

[0012] Furthermore, the bottom sealing mechanism includes a bottom sealing base plate fixed to the main support and a first bottom sealing adjusting screw and a second bottom sealing adjusting screw rotatably connected to the bottom sealing base plate. A synchronous belt is arranged between the first bottom sealing adjusting screw and the second bottom sealing adjusting screw. The bottom sealing base plate is provided with a first bottom sealing adjusting guide rod and a second bottom sealing adjusting guide rod. The first bottom sealing adjusting guide rod is slidably connected to a first bottom sealing slide seat provided thereon, and the second bottom sealing adjusting guide rod is slidably connected to a second bottom sealing slide seat provided thereon. The first bottom sealing slide seat and the second bottom sealing slide seat are respectively provided with a first bottom sealing adjusting nut and a second bottom sealing adjusting nut correspondingly sleeved on the first bottom sealing adjusting screw and the second bottom sealing adjusting screw. The second bottom sealing slide seat is provided with a bottom sealing cylinder, and the bottom sealing cylinder is provided with a bottom sealing knife holder. The first bottom sealing knife is fixed on the first bottom sealing slide seat, and the bottom sealing knife holder is provided with a bottom sealing knife holder. The system includes a sealing guide rod and a second bottom sealing knife. The bottom sealing guide rod is slidably connected to the second bottom sealing slide. When the bottom sealing cylinder pushes the bottom sealing knife seat to extend and retract, the second bottom sealing knife mounted on it is pressed against or moved away from the first bottom sealing knife. One end of the first bottom sealing adjusting screw is fixed with a bottom sealing adjusting handwheel. When the bottom sealing adjusting handwheel is rotated, the first bottom sealing adjusting screw and the second bottom sealing adjusting screw rotate together. The first bottom sealing adjusting nut and the second bottom sealing adjusting nut, respectively fitted on the first bottom sealing adjusting screw and the second bottom sealing adjusting screw, move up and down to adjust the up and down positions of the first bottom sealing knife and the second bottom sealing knife. Each of the first bottom sealing knife and the second bottom sealing knife is provided with a bottom sealing heating tube for heating the corresponding bottom sealing knife.

[0013] Furthermore, the side sealing mechanism includes a pair of opposing first and second side sealing plates, a side sealing adjustment slide arranged between the two side sealing plates, and a pair of side sealing blades for the packaging film to pass through the gap between them. Each side sealing blade is equipped with a side sealing heating tube and at least one of the side sealing blades is equipped with a side sealing thermocouple for adjusting the temperature of the side sealing blade. One side sealing blade is fixed on the first side sealing plate, and the other side sealing blade is fixed on the side sealing slide. The first and second side sealing plates are fixed on the side sealing adjustment slide. A pair of first and second side sealing guide rods that are slidably connected to the side sealing slide are connected and fixed between the first and second side sealing plates. A side sealing cylinder is provided on the second side sealing plate to drive the side sealing slide to slide so that the pair of side sealing blades close or open to achieve side sealing of the packaging film.

[0014] Furthermore, the film feeding device includes a first bag-pulling film mechanism, which includes a first bag-pulling film motor and a first bag-pulling film roller driven by the first bag-pulling film motor. The first bag-pulling film roller is equipped with a first upper bag-pulling film wheel and a first lower bag-pulling film wheel. A second upper bag-pulling film wheel and a second lower bag-pulling film wheel are also equipped on the second bag-pulling film roller. The positions of the first lower bag-pulling film wheel and the second lower bag-pulling film wheel can be adjusted vertically above and below the first bag-pulling film roller, respectively. The second bag-pulling film roller is mounted on a first clutch plate. A first clutch cylinder mounted on the first clutch plate can pull the first clutch plate to swing, thereby driving the second upper bag-pulling film wheel. The second pull-down bag film roller disengages from the first pull-up bag film roller and the first pull-down bag film roller. After the packaging bag film passes through the gap between the two pull-down bag film rollers, the first clutch cylinder extends, causing the second pull-up bag film roller and the second pull-down bag film roller to press against the first pull-up bag film roller and the first pull-down bag film roller. Thus, under the drive of the first pull-down bag film motor, a fixed length of packaging bag film is transported. The first pull-down bag film mechanism also includes an upper limit plate and a lower limit plate for positioning the packaging bag film entering it, a pair of bag film guards for escorting the packaging bag film through it, and a bag film position detector that cooperates with the first pull-down bag film motor to detect the position of the packaging bag film.

[0015] Furthermore, the cutting mechanism includes a cutting movable frame and a cutting guide rail mounted thereon, as well as a cutting slider mounted on the cutting guide rail. A cutting moving blade is mounted on the cutting slider, and a cutting driver and a cutting fixed blade are mounted on the cutting movable frame. The cutting driver is used to drive the cutting slider to slide along the cutting guide rail, thereby driving the cutting moving blade to move. When the cutting moving blade moves, it cooperates with the cutting fixed blade to cut the film to be packaged into individual face mask bags.

[0016] Furthermore, the cutting mechanism also includes a cutting fixed frame fixed to the main support. The cutting fixed frame is equipped with a translational slide rail and a translational cylinder. The translational slide rail is equipped with a translational slider that can slide along it. The cutting movable frame is fixed on the translational slider. The cylinder rod of the translational cylinder is connected to the cutting movable frame. By extending and retracting the cylinder rod, the cutting movable frame is driven to move the cutting fixed blade and the cutting moving blade to the first cutting position and the second cutting position, respectively.

[0017] Furthermore, the bag-making device also includes a bag film roll feeding mechanism for placing the bag film roll material to be packaged as a bag film. The bag film roll feeding mechanism includes a pair of bag film roll support arms, an air shaft mounted on the pair of bag film roll support arms and on which a bag film roll material is mounted, a meshing air shaft driven gear and an air shaft driving gear and an air shaft drive motor disposed on one of the bag film roll support arms, the air shaft driven gear being disposed at one end of the air shaft, and the air shaft drive motor being drivenly connected to the air shaft driving gear. A bag film roll pulling cylinder is disposed at the end of each bag film roll support arm away from the free end, and each bag film roll pulling cylinder synchronously performs telescopic movements to correspondingly realize the loading and feeding of the bag film roll material.

[0018] Furthermore, the bag-making device also includes a first buffer mechanism. The first buffer mechanism includes a first buffer fixed roller, a first buffer movable roller and a second buffer fixed roller through which the bag film to be packaged output by the bag film unloading mechanism passes in sequence, a pair of main support side plates fixed on the main support, and a pair of first buffer slide rails and a first buffer slide seat provided on each of them. The first buffer fixed roller and the second buffer fixed roller are rotatably connected between the pair of main support side plates. The first buffer movable roller is provided on the pair of first buffer slide seats. Each first buffer slide seat can slide up and down along the corresponding first buffer slide rail. In addition, each first buffer slide seat is provided with a first buffer tension cylinder for tightening the first buffer movable roller.

[0019] Furthermore, the bag-making device also includes a folding mechanism for folding the film to be packaged. The folding mechanism includes a folding mechanism fixing frame, a correction screw and a correction motor mounted on the folding mechanism fixing frame and driven to be connected, a correction nut sleeved on the correction screw, a folding mechanism slide rail mounted on the folding mechanism fixing frame, and a folding mechanism movable frame slidably connected to the folding mechanism slide rail. The correction nut is fixed on the folding mechanism movable frame. When the correction motor drives the correction screw to rotate and correct the deviation, the correction nut sleeved on the correction screw moves, thereby driving the folding mechanism movable frame to move along the folding mechanism slide rail. A folding plate is mounted on the folding mechanism movable frame. A pair of folded film delivery guide rollers are mounted at the end of the folding plate. A folding cutter is mounted below the folding plate. The folded film to be packaged is delivered between the pair of folded film delivery guide rollers. The folding cutter cuts the folded position of the delivered film to be packaged.

[0020] Furthermore, the film feeding device also includes a second bag-pulling film mechanism, which includes a second bag-pulling film motor, a third bag-pulling film roller, a fourth bag-pulling film roller, and a second clutch cylinder. The second bag-pulling film motor drives the third bag-pulling film roller to rotate, and the fourth bag-pulling film roller is mounted on a second clutch plate. The second clutch cylinder is drivenly connected to the second clutch plate and can pull the second clutch plate to swing, thereby causing the fourth bag-pulling film roller to disengage from the third bag-pulling film roller, so that the bag film to be packaged can pass through the gap between the third bag-pulling film roller and the fourth bag-pulling film roller. After the bag film to be packaged has passed through, the second clutch cylinder extends, causing the fourth bag-pulling film roller to press against the third bag-pulling film roller, thereby pulling the bag film to be packaged under the drive of the second bag-pulling film motor.

[0021] Furthermore, an upper cutting blade and a lower cutting blade are arranged in front of the second bag-pulling film mechanism relative to the direction of movement of the bag film to be packaged. The bag-making device also includes an edge material collection mechanism, which includes an upper edge material guide ring, a lower edge material guide ring, an edge material buffer guide ring, a total edge material guide ring, an edge material collection guide ring, and an edge material collection turntable. The upper edge material cut by the upper cutting blade passes through the upper edge material guide ring, the edge material buffer guide ring, the total edge material guide ring, and the edge material collection guide ring to reach the edge material collection turntable. The lower edge material cut by the lower cutting blade passes through the lower edge material guide ring, the upper edge material guide ring, the edge material buffer guide ring, the total edge material guide ring, and the edge material collection guide ring to reach the edge material collection turntable. The ring reaches the edge material collection turntable; the edge material collection mechanism also includes an edge material collection motor that drives the edge material collection turntable to rotate, a reciprocating screw that rotates together with the edge material collection turntable via a synchronous belt, and a reciprocating nut that cooperates with the reciprocating screw, so that the reciprocating nut can move back and forth on the reciprocating screw. An edge material collection guide ring is provided on the reciprocating nut. The upper edge material and the lower edge material are evenly wound around the edge material collection turntable back and forth through the edge material collection guide ring. An edge material buffer guide ring is provided on the edge material buffer slide. The edge material buffer slide moves up and down along the edge material buffer guide rod to buffer both the upper edge material and the lower edge material.

[0022] Furthermore, the bag-making device also includes a second buffer mechanism, which includes a pair of third buffer fixed rollers and a second buffer slide rail mounted on the main support. The pair of third buffer fixed rollers are rotatably connected to the main support. A second buffer slide seat is slidably connected on the second buffer slide rail. A second buffer movable roller and a second buffer tension cylinder are mounted on the second buffer slide seat. After the packaging bag film is sent out from the second bag-pulling mechanism, it passes through the third buffer fixed rollers and the second buffer movable rollers. The second buffer tension cylinder applies a tension to the second buffer movable roller to keep the packaging bag film taut.

[0023] Furthermore, the bag-making device also includes a punching mechanism, which includes an upper and lower slide block for easy-tear holes, an easy-tear hole puncher fixed on the upper and lower slide block for easy-tear holes, and front and rear slide blocks for easy-tear holes. The upper and lower slide block for easy-tear holes is provided with an easy-tear hole up and down adjustment nut, which is sleeved on the easy-tear hole up and down adjustment screw. One end of the easy-tear hole up and down adjustment screw is equipped with an easy-tear hole up and down adjustment handwheel. The easy-tear hole up and down adjustment guide rod is fixed on the easy-tear hole front and rear slide blocks for easy-tear holes. The easy-tear hole front and rear slide blocks for easy-tear holes can slide along the easy-tear hole front and rear adjustment guide rod fixed on the easy-tear hole base. The easy-tear hole front and rear adjustment nut is provided on the easy-tear hole front and rear slide blocks for easy-tear holes, which is sleeved on the easy-tear hole front and rear adjustment screw. One end of the easy-tear hole front and rear adjustment screw is equipped with an easy-tear hole front and rear adjustment handwheel.

[0024] Furthermore, the bag feeding device also includes a bag receiving mechanism and a collection belt. The bag receiving mechanism includes a first steering drive, a second steering drive, a suction cup fixing plate, and a suction cup. After the suction cup picks up the mask bag cut by the cutting mechanism, the first steering drive rotates the mask bag, which is in the same direction as the transport of the bag film to be packaged, by 90 degrees. The second steering drive then rotates the mask bag by another 90 degrees and the suction cup releases the mask bag onto the collection belt.

[0025] The fully automatic facial mask packaging machine of this invention has the following advantages: by setting up a folding device, a bag-making device, and a bag-feeding device, it can realize the various processes of making facial mask bags, folding facial mask sheets, and packaging facial mask sheets relatively independently. The bag film roll material is sealed by the side and bottom and then promptly filled into the facial mask sheet, thereby eliminating the generation of empty facial mask bags and improving production quality. It also saves the time required for separately purchasing bag-making equipment, setting up a separate bag-making process, and transferring bag-making costs, thus reducing the production cost of facial mask bags and increasing production efficiency, thereby saving costs for manufacturers.

[0069] refer to Figures 1 to 25As an objective of this invention, a fully automatic facial mask packaging machine is provided, comprising a folding device 1000, a bag-making device 2000, and a bag-feeding device 3000. The folding device 1000 includes a folding mechanism 1100, which includes a folding support 1101, a facial mask fabric conveyor belt 1102 mounted on the folding support 1101, and a facial mask fabric folding assembly for folding the facial mask fabric to be folded conveyed from the facial mask fabric conveyor belt 1102. The facial mask fabric folding assembly performs three folds on the facial mask fabric and is located at the end of the facial mask fabric conveyor belt 1102. The membrane fabric folding assembly includes a movable single-fold blade 1103, a single-fold forming device 1104 docked with the single-fold blade 1103, a movable double-fold blade 1105 perpendicular to the single-fold blade 1103, a double-fold forming device 1106 docked with the double-fold blade 1105, a movable triple-fold blade 1107 perpendicular to the double-fold blade 1105, and a movable film loading plate 1108 docked with the triple-fold blade 1107 to accommodate it. The single-fold forming device 1104 and the double-fold forming device 1106 are fixedly connected to the folding bracket 1101. The folding mechanism 1100 is connected via the film loading plate. 1108 connects to the bag-making device 2000, so that after multiple folds, the folded mask fabric is directly fed into the film-filling insert 1108 and awaits loading into the bag-making device 2000. The bag-making device 2000 includes a main support 2001, a side-sealing mechanism 2200 mounted on the main support 2001 for side-sealing the film to be packaged, and a cutting mechanism 2300 mounted on the main support 2001 for cutting the film to be packaged into individual mask bags 5000. It should be noted that the film to be packaged is obtained by feeding the film roll 4000 from the bag-feeding device 3000, and the mask bags 5000 are... The process involves placing the folded mask sheet into the packaging bag film, then sealing it with a side-sealing mechanism 2200 and cutting it with a cutting mechanism 2300. The cutting mechanism 2300 cuts at the middle position of the side-sealing mechanism 2200. The side-sealing mechanism 2200 forms the two sides of the mask bag adjacent to the opening of the packaging bag film. After the side seal is cut in half by the cutting mechanism 2300, it becomes the side of a single mask bag 5000. The bag feeding device 3000 is set on the main support 2001 to provide power for the movement of the packaging bag film and the mask bag 5000.Therefore, the fully automatic facial mask packaging machine of the present invention is equipped with a relatively separate folding device 1000, a bag-making device 2000, and a bag-feeding device 3000, which can realize the working mode of making bags, folding, and packaging facial mask sheets at the same time. In the production process, the bag film roll 4000 is fed out by the bag-feeding device 3000 as the bag film to be packaged. The facial mask sheets are then placed in the bag film at intervals according to the bag width. After side sealing, the side sealing is also done at intervals according to the bag width to separate the facial mask sheets. Then, it is cut into individual finished facial mask bags 5000 containing facial mask sheets according to the bag width. In other words, the packaging film delivered from the 4000 roll of film is promptly loaded into the mask fabric. This eliminates the need for pre-made stacks of finished mask bags as in existing technologies, thus avoiding the need to continuously take individual mask bags from stacks. As a result, empty mask bags are eliminated. Furthermore, since the bag is made, folded, and loaded with mask fabric simultaneously, the time required for purchasing separate bag-making equipment, setting up a separate bag-making process, and transferring bag-making costs is saved. This reduces the production cost of mask bags, increases production efficiency, and saves money for the manufacturer.

[0070] refer to Figures 2 to 5 Specifically, in this embodiment, the mask fabric folding assembly may also be provided with a one-fold push rod 1110 and a two-fold push rod 1111 for pushing the mask fabric, corresponding to the one-fold forming device 1104 and the two-fold forming device 1106, respectively. A film-pushing cylinder 1112 and a film-pushing block 1113 for providing pushing force to the mask fabric may also be provided on the film-loading insert plate 1108. Furthermore, the folding mechanism 1100 may also include a film-loading mask fabric detector 1114 and a film-loading push rod 1115, and the film-loading insert plate 1108 is also provided with two through holes facing the film-loading mask fabric detector 1114 and the film-loading push rod 1115. Preferably, the folding mechanism 1100 can also be equipped with a single-fold mask fabric detector 1109. When the mask fabric conveyor belt 1102 transports the mask fabric to be folded to below the single-fold cutter 1103, after the single-fold mask fabric detector 1109 senses the mask fabric, the single-fold cutter 1103 performs, for example, a downward folding action, folding the mask fabric to be folded into the single-fold forming device 1104 below. Then, the double-fold cutter 1105 performs a folding action, folding the mask fabric again into the double-fold forming device 1106. Then, the triple-fold cutter 1107 performs a folding action, performing a third fold on the mask fabric. The film loading plate 1108 is connected to the triple-fold cutter 1107, and the film loading plate 1108 can accommodate the triple-fold cutter 1107. Thus, after the triple-fold cutter 1107 performs the third fold, it directly sends the folded mask fabric into the film loading plate 1108 and waits to be loaded into the bag making device 2000. In this way, the mask fabric folding assembly has the advantages of compact structure and reliable operation.

[0071] Further reference Figure 1 , Figure 6 , Figure 12, Figure 18 Preferably, the bag-making device 2000 further includes a bottom-sealing mechanism 2100 disposed on the main support 2001 for sealing the bottom edge of the bag film to be packaged. The bottom-sealing mechanism 2100 forms the bottom edge of the bag film to be packaged opposite to the opening of the mask bag. The bag film to be packaged is first bottom-sealed by the bottom-sealing mechanism 2100, and then side-sealed by the side-sealing mechanism 2200. In this way, in cases where the bottom of the bag film to be packaged needs to be sealed first, the bottom-sealing mechanism 2100 can complete the bottom sealing.

[0072] Please refer to further information. Figure 2 and Figure 4 Preferably, the bag-making device 2000 further includes an opening mechanism 1200 disposed on the folding bracket 1101 for opening the packaging bag film. The film-loading plate 1108 of the folding mechanism 1100 is connected to the two pieces of the packaging bag film that have been opened on the bag-making device 2000, so that the inner cavity formed by the two pieces of the packaging bag film is waiting to be loaded with the folded mask cloth. We define the order of the packaging bag film's movement as front and back. The opening mechanism 1200 is located in front of the side sealing mechanism 2200. The opening mechanism 1200 includes a front support rod 1201, a rear support rod 1202 and a side guide plate 1203 fixed on the folding base plate 1116 of the folding mechanism 1100. The front support rod 1201 is inserted into the lower middle part of the packaging bag film to open the packaging bag film. The rear support rod 1202 and the side guide plate 1203 are used to maintain the shape of the packaging bag film opened by the front support rod 1201. In this way, the spreading mechanism 1200 can reliably spread the two pieces of the packaging film, ensuring that the folded mask cloth is smoothly inserted into the packaging film. It should be noted that the front support rod 1201 does not need to be inserted into the lower middle part of the packaging film. However, in this case, since the lower middle part of the packaging film is not fully spread, when the film insert plate 1108 with the folded mask cloth is inserted between the two pieces of the packaging film spread by the spreading mechanism 1200, the film insert plate 1108 may scrape the lower middle part of the packaging film, thereby scratching the inside of the packaging film. Alternatively, the front support rod 1201, the rear support rod 1202 and the side guide plate 1203 can be made into a whole, which can also achieve the same effect.

[0073] Please refer to further information. Figures 2 to 5Specifically, the folding device 1000 further includes a folding mechanism adjustment assembly 1300. The folding mechanism adjustment assembly 1300 includes a folding mechanism slide rail 1301 and a folding mechanism adjusting screw 1302 mounted on the main support 2001, a folding mechanism slider 1303 and a folding mechanism adjusting nut 1304 mounted on the folding support 1101. The folding mechanism adjusting screw 1302 is rotatably connected to the main support 2001. One end of the folding mechanism adjusting screw 1302 is fixedly equipped with a folding mechanism adjusting handwheel 1305. The folding mechanism slider 1303 is connected to the folding mechanism slide rail 1304. The rail 1301 is slidably connected, and the folding mechanism adjusting nut 1304 is sleeved on the folding mechanism adjusting screw 1302. Therefore, the folding mechanism adjusting handwheel 1305 is rotated to drive the folding mechanism adjusting screw 1302 to rotate, which in turn drives the folding mechanism adjusting nut 1304 to move translationally. Thus, by rotating the folding mechanism adjusting handwheel 1305, the front and rear positions of the folding mechanism 1100 can be adjusted. Therefore, the front and rear positions of the folding mechanism 1100 can be adjusted, thereby achieving the function of adjusting the position of the folding device 1000 loading the mask cloth into the bag making device 2000.

[0074] Please refer to the diagram for further details. Figure 12Specifically, the bottom sealing mechanism 2100 includes a bottom sealing base plate 2101 fixed to the main support 2001 and a first bottom sealing adjusting screw 2102 and a second bottom sealing adjusting screw 2103 rotatably connected to the bottom sealing base plate 2101. After the packaging bag film is folded by the folding mechanism 2600, it enters the bottom sealing mechanism 2100 through the gap between a pair of bottom sealing front guide rollers 2118. A synchronous belt is arranged between the first bottom sealing adjusting screw 2102 and the second bottom sealing adjusting screw 2103. The bottom sealing base plate 2101 is provided with a first bottom sealing adjusting guide rod 2104 and a second bottom sealing adjusting guide rod 2105. The first bottom seal adjusting guide rod 2104 is slidably connected to the first bottom seal slide 2106 mounted thereon, and the second bottom seal adjusting guide rod 2105 is slidably connected to the second bottom seal slide 2107 mounted thereon. The first bottom seal slide 2106 and the second bottom seal slide 2107 are respectively provided with a first bottom seal adjusting nut 2108 and a second bottom seal adjusting nut 2109 correspondingly sleeved on the first bottom seal adjusting screw 2102 and the second bottom seal adjusting screw 2103. The second bottom seal slide 2107 is provided with a bottom seal cylinder 2110, and the bottom seal cylinder 2110 is provided with a bottom seal knife holder 2111. A first bottom sealing knife 2112 is fixed on a first bottom sealing slide 2106. A bottom sealing knife holder 2111 is provided with a bottom sealing guide rod 2114 and a second bottom sealing knife 2113. The bottom sealing guide rod 2114 is slidably connected to the second bottom sealing slide 2107. When the bottom sealing cylinder 2110 pushes the bottom sealing knife holder 2111 to extend and retract, the second bottom sealing knife 2113 mounted thereon is pressed against or moved away from the first bottom sealing knife 2112. A bottom sealing adjusting handwheel 2115 is fixed to one end of the first bottom sealing adjusting screw 2102. When the bottom sealing adjusting handwheel 2115 is rotated, the first bottom sealing adjusting screw 2102 and the second bottom sealing knife 2113 are pressed against or moved away from the first bottom sealing knife 2112. The two bottom-seal adjusting screws 2103 rotate together, and the first bottom-seal adjusting nuts 2108 and 2109, respectively fitted onto the first bottom-seal adjusting screws 2102 and 2103, move up and down to adjust the vertical positions of the first bottom-seal blade 2112 and 2113. Each of the first bottom-seal blades 2112 and 2113 is equipped with a bottom-seal heating element 2116 for heating the corresponding bottom-seal blade. At least one of the first and second bottom-seal blades is equipped with a bottom-seal thermocouple 2117 for controlling the bottom-seal heating element 2116. Since the folded packaging film varies in width, the upper height of the packaging film can be kept constant, while the lower height of the packaging film will change with the width of the film. Therefore, by setting the above-mentioned structures for adjusting the bottom-seal blades, the height position of each bottom-seal blade can be adjusted to accommodate packaging films of different widths.

[0075] Please refer to further information. Figure 13Specifically, the side sealing mechanism 2200 includes a pair of opposing first side sealing plates 2201 and second side sealing plates 2202, a side sealing adjusting slide 2203 arranged between the two side sealing plates, and a pair of side sealing blades 2204 for the packaging film to pass through the gap between them. Each side sealing blade 2204 is equipped with a side sealing heating tube 2205 and at least one side sealing blade is equipped with a side sealing thermocouple for adjusting the temperature of the side sealing blade 2204. One side sealing blade 2204 is fixed on the first side sealing plate 2201, and the other side sealing blade 2202 is fixed on the second side sealing plate 2202. 04 is fixed on the side sealing slide 2207. The first side sealing plate 2201 and the second side sealing plate 2202 are fixed on the side sealing adjustment slide 2203. A pair of first side sealing guide rods 2208 and second side sealing guide rods 2209, which are slidably connected to the side sealing slide 2207, are connected and fixed between the first side sealing plate 2201 and the second side sealing plate 2202. A side sealing cylinder 2210 is provided on the second side sealing plate 2202 to drive the side sealing slide 2207 to slide so that a pair of side sealing knives 2204 can close or open to achieve side sealing of the packaging bag film. Since the folded mask cloth is loaded in the middle of the folded front and back bag films, by setting the above-mentioned side sealing mechanism 2200, the packaging bag film can be side sealed according to the width required to accommodate the mask cloth, and the mask cloth located in the middle of the packaging bag film can be sealed in the middle of two adjacent side sealing edges.

[0076] Preferably, the side sealing mechanism 2200 further includes a side sealing position adjustment mechanism, which includes a side sealing adjustment nut 2211 provided on the side sealing adjustment slide 2203, the side sealing adjustment nut 2211 being sleeved on the side sealing adjustment screw 2212, a side sealing adjustment handwheel 2213 provided at one end of the side sealing adjustment screw 2212, and at least one side sealing adjustment guide rod 2214 provided on a 2215 spaced apart from the side sealing adjustment slide 2203, the rotating side sealing adjustment handwheel 2213... The side sealing adjusting screw 2212 is rotated together, which in turn moves the side sealing adjusting nut 2211 sleeved on the side sealing adjusting screw 2212, thereby moving a pair of side sealing blades 2204 on the side sealing adjusting slide 2203 to adjust the side sealing position of the packaging bag film. Therefore, by setting the side sealing position adjusting mechanism of the above-mentioned side sealing mechanism, the side sealing position of the packaging bag film can be adjusted, so as to adapt to folded mask cloths of different sizes and obtain mask bags of the desired size.

[0077] Please refer to further information. Figure 14 and Figure 15Specifically, the bag feeding device includes a first bag-pulling film mechanism 3100. In this embodiment, the first bag-pulling film mechanism 3100 is located in front of the cutting mechanism 2300. The first bag-pulling film mechanism 3100 includes a first bag-pulling film motor 3101 and a first bag-pulling film roller 3102 driven by the first bag-pulling film motor 3101. The first bag-pulling film roller 3102 can mesh with a second bag-pulling film roller 3106 through a first bag-pulling film roller gear 3103. A first upper bag-pulling film wheel 3104 and a first lower bag-pulling film wheel 3105 are provided on the first bag-pulling film roller 3102. A second upper bag-pulling film wheel 3107 and a second lower bag-pulling film wheel 3108 are provided on the second bag-pulling film roller 3106. The positions of the bag film roller 3105 and the second pull-down bag film roller 3108 can be adjusted up and down above the first pull-up bag film roller 3102 and the second pull-down bag film roller 3106, respectively. The second pull-down bag film roller 3106 is mounted on the first clutch plate 3109. The first clutch cylinder 3110 mounted on the first clutch plate 3109 can pull the first clutch plate 3109 to swing, thereby causing the second pull-up bag film roller 3107 and the second pull-down bag film roller 3108 to disengage from the first pull-up bag film roller 3104 and the first pull-down bag film roller 3105. After the packaging bag film passes through the gap between the two pull-down bag film rollers, the first clutch cylinder 3110 extends, causing the second pull-up bag film roller 3107 and the second pull-down bag film roller 3108 to press against the first pull-down bag film roller 3105. The first pull-up film roller 3104 and the first pull-down film roller 3105, driven by the first pull-up film motor 3101, transport a fixed length of the film to be packaged to the cutting mechanism 2300. Since the width of the film to be packaged (equal to the length of the cut mask bag 5000) varies, the positions of the first pull-down film roller 3105 and the second pull-down film roller 3108 need to be adjusted vertically. Because a mask sheet needs to be inserted into the film to be packaged, a passageway for the mask sheet needs to be provided between the first pull-up film roller 3104 and the first pull-down film roller 3105, and between the second pull-up film roller 3107 and the second pull-down film roller 3108. Generally, the second pull-up film roller 3106 does not need to pass through the teeth of the first pull-up film roller. The first bag-pulling mechanism 3100 rotates by meshing with the first upper bag-pulling roller 3104 and the second upper bag-pulling roller 3107, the first lower bag-pulling roller 3105 and the second lower bag-pulling roller 3108, and transmits power to drive the second bag-pulling roller 3106 to rotate. The first bag-pulling mechanism 3100 also includes an upper limit plate 3111 and a lower limit plate 3112 for positioning the bag film to be packaged that enters therein, a pair of bag film guard plates 3113 for escorting the bag film to be packaged through therein, and a bag film position detector 3114 that cooperates with the first bag-pulling motor 3101 to detect the position of the bag film to be packaged. The bag film position detector 3114 is located in front of the first bag-pulling mechanism 3100.Therefore, since the first bag-pulling film mechanism 3100 is provided in front of the cutting mechanism 2300, it can provide power for transporting the fixed-length packaging bag film to the cutting mechanism 2300. Thus, when the first bag-pulling film mechanism 3100 is transporting the fixed-length packaging bag film, the cutting mechanism 2300 can perform a cutting operation according to the transported fixed-length packaging bag film, and cut the fixed-length packaging bag film into a fixed-length mask bag 5000.

[0078] Please refer to further information. Figure 16 and Figure 17 Specifically, the cutting mechanism 2300 includes a cutting movable frame 2301 and a cutting guide rail 2302 disposed thereon, and a cutting slider 2303 disposed on the cutting guide rail 2302. A cutting moving blade 2304 is disposed on the cutting slider 2303. A cutting driver 2305 and a cutting fixed blade 2306 are disposed on the cutting movable frame 2301. The cutting driver 2305 is used to drive the cutting slider 2303 to slide along the cutting guide rail 2302, thereby driving the cutting moving blade 2304 to move. When the cutting moving blade 2304 moves, it cooperates with the cutting fixed blade 2306 to cut the film to be packaged, and cuts from the middle position of the side seal. In this way, a precisely cut fixed-length film to be packaged can be obtained and then made into a finished mask bag 5000.

[0079] Please refer to further information. Figure 18 , Figure 18 The principle diagram illustrates the relative positions of adjacent arc angles and two different cutting positions. The cutting mechanism 2300 also includes a cutting fixing frame 2307 fixed to the main support 2001. The cutting fixing frame 2307 is equipped with a translational slide rail 2308 and a translational cylinder 2309. The translational slide rail 2308 is equipped with a translational slider 2310 that can slide along it. The cutting movable frame 2301 is fixed on the translational slider 2310. The cylinder rod of the translational cylinder 2309 is connected to the cutting movable frame 2301. The extension and retraction of the cylinder rod drive the cutting frame 2301, which in turn moves the fixed cutting blade 2306 and the moving cutting blade 2304 to the first and second cutting positions, respectively. In this case, for the mask bag 5000 with rounded corners, a rounded hole punch is needed. The cutting mechanism 2300 must cut precisely along the center line of the rounded corners without any deviation; otherwise, the rounded corners of the cut mask bag 5000 will have barbs, failing to meet quality requirements. Therefore, referring to… Figure 18The fully automatic facial mask packaging machine of the present invention utilizes a cutting mechanism 2300 to perform two cuts at a first cutting position and a second cutting position on both sides of the arc angle midline between two adjacent first and second facial mask bags whose bottom and side edges have been sealed respectively. This achieves one cut on each side of the arc angle midline, thereby avoiding the disadvantage of not being able to ensure that the cut is exactly on the arc angle midline each time. Thus, it solves the technical problem of barbs in the prior art. After the two cuts, the waste material cut off is blown into the cutting waste collection hopper 2312 through the waste blowing pipe 2311 set on the cutting frame 2301.

[0080] Please refer to further information. Figure 10 Specifically, the bag-making apparatus 2000 further includes a bag film roll placement mechanism 2400 for placing the bag film roll 4000, which is to be formed into a packaging bag film. The bag film roll placement mechanism 2400 includes a pair of bag film roll support arms 2401, an air shaft 2402 mounted on the pair of bag film roll support arms 2401 and on which a bag film roll 4000 is mounted, a meshing air shaft driven gear 2403 and an air shaft driving gear 2404 disposed on one of the bag film roll support arms 2401, and an air shaft drive motor 2405. The air shaft 2402 can expand when inflated to fix the bag film roll 4000. The air shaft driven gear 2403 is disposed at one end of the air shaft 2402, and the air shaft drive motor 2405 meshes with the air shaft driving gear. The wheel 2404 drives the air shaft 2402 to rotate and transport the packaging film. A film roll pull cylinder 2406 is set at the end of each film roll support arm 2401 away from the free end. Each film roll pull cylinder 2406 moves synchronously to load and feed the film roll 4000. More specifically, when the film roll 4000 is to be loaded, the film roll pull cylinder 2406 extends and the film roll support arm 2401 moves to the lower position. When the film roll 4000 is loaded and the bag making work is to be performed, the film roll pull cylinder 2406 retracts and the film roll support arm 2401 moves to the upper position to lift the film roll 4000. The film roll feeding mechanism 2400 then performs the film feeding work. Therefore, because the bag film roll feeding mechanism 2400 has a reliable structure and stable operation, it ensures that the bag film roll 4000 can be reliably and precisely transported to various subsequent working positions.

[0081] Please refer to further information. Figure 7Specifically, the bag-making device 2000 further includes a first buffer mechanism 2500. The first buffer mechanism 2500 includes a first buffer fixed roller 2501, a first buffer movable roller 2502, and a second buffer fixed roller 2503 through which the bag film output from the bag film unloading mechanism 2400 passes in sequence; a pair of main support side plates 2504 fixed on the main support 2001; and a pair of first buffer slide rails 2505, each with a first buffer slide block 2506. The first buffer fixed roller 2501 and the second buffer fixed roller 2503 are rotatably connected to a... Between the main support side plates 2504, the first buffer movable roller 2502 is set on a pair of first buffer slides 2506. Each first buffer slide 2506 can slide up and down along the corresponding first buffer slide rail 2505, so that the first buffer movable roller 2502 can also move up and down to buffer the packaging film. In addition, each first buffer slide 2506 is provided with a first buffer tension cylinder 2507 for tightening the first buffer movable roller 2502, so that the packaging film on the first buffer movable roller 2502 is always in a taut state.

[0082] More preferably, a first buffer position detector 2508 is also provided on the first buffer slide 2506 to detect the position of the first buffer movable roller 2502, thereby adjusting the speed of the front-end bag film feeding mechanism 2400.

[0083] Please refer to further information. Figure 8Specifically, the bag-making device 2000 also includes a folding mechanism 2600 for folding the film to be packaged. The folding mechanism 2600 includes a folding mechanism fixing frame 2601, a correction screw 2602 and a correction motor 2603 mounted on the folding mechanism fixing frame 2601 and drivenly connected, a correction nut 2604 sleeved on the correction screw 2602, a folding mechanism slide rail 2605 mounted on the folding mechanism fixing frame 2601, and a folding mechanism slide rail 2605 slidably connected to the folding mechanism slide rail 2605. The folding mechanism has a movable frame 2606, on which a straightening nut 2604 is fixed. When the straightening motor 2603 drives the straightening screw 2602 to rotate and straighten, the straightening nut 2604 on the straightening screw 2602 moves, thereby driving the folding mechanism to move along the folding mechanism slide rail 2605. A folding plate 2607 is provided on the folding mechanism to fold the film to be packaged. A pair of folded film feeding guide rollers 2608 are provided at the end of the folding plate 2607, and a folding cutter 2609 is provided below the folding plate 2607. The folded film to be packaged is fed out between the pair of folded film feeding guide rollers 2608, and the folding cutter 2609 cuts the folded position of the film to be packaged. Since the fold line of the packaging bag film will be raised after folding, resulting in an uneven film, the folding mechanism 2600 can be set to cut the film in half at the fold position, thereby eliminating the raised fold line.

[0084] Sometimes, some manufacturers do not have high quality requirements for the 5000-size face film bag, so they do not need to cut the packaging bag film at the fold position, nor do they need to cut the top and bottom edges of the packaging bag film. In this case, there will be no opening at the bottom of the packaging bag film, so there is no need to seal the bottom of the packaging bag film. At this time, there is no need to set up the bottom sealing mechanism 2100.

[0085] Please refer to further information. Figure 9Preferably, the folding mechanism 2600 further includes a folding mechanism height adjustment mechanism, which includes a main support horizontal plate 2610 fixed on the main support side plate 2504, a folding mechanism height adjustment screw 2611 disposed on the main support horizontal plate 2610, and a folding mechanism height adjustment nut 2618 sleeved on the folding mechanism height adjustment screw 2611. The upper and lower ends of the folding mechanism height adjustment screw 2611 are respectively provided with a folding mechanism height adjustment handwheel 2612 and a folding mechanism height adjustment seat 2613 rotatably connected thereto. By rotating the folding mechanism height adjustment handwheel 2612, the height of the folding mechanism fixing frame 2601 can be adjusted. The folding mechanism height adjustment seat 2613 is disposed on the folding mechanism fixing frame 2601. A pair of folding mechanism lifting slide rails 2614 are disposed on the main support side plate 2504. The two ends of the folding mechanism fixing frame 2601 are slidably connected to the folding mechanism lifting slide rails 2614 by a fixing frame slider. Since the packaging film is transported by the second buffer fixed roller 2503 to the folding mechanism 2600, the function of the folding mechanism 2600 is to fold the packaging film in half. However, since the mask bags 5000 are of different sizes, the width of the packaging film is also different, and the height of the packaging film after folding is also different. Therefore, by setting a height adjustment mechanism for the folding mechanism, the height of the folding mechanism 2600 can be adjusted.

[0086] Please refer to further information. Figure 8Preferably, the folding mechanism 2600 further includes a bag film position adjusting screw 2615 mounted on the folding mechanism movable frame 2606. A bag film position adjusting nut (not shown) is fitted onto the bag film position adjusting screw 2615, and a bag film position adjusting handwheel 2616 is mounted on one free end of the screw. A bag film side position detector 2617 is mounted on the bag film position adjusting nut to detect the side position of the bag film. The bag film side position detector 2617 feeds back the detected position signal to the correction motor 2603, which then performs correction movements. Specifically, when the bag film position adjustment handwheel 2616 is rotated to adjust the position of the bag film side position detector 2617, the bag film edge is required to be in the same position as the bag film side position detector 2617. If the bag film edge deviates from the position of the bag film side position detector 2617, the bag film side position detector 2617 will send a signal to the correction motor 2603. The correction motor 2603 performs the correction action to calibrate the folding mechanism movable frame 2606 together with the folding plate 2607 fixed thereon and the bag film side position detector 2617. In this case, since the width of the bag film roll 4000 varies when loading, the position of the bag film roll 4000 on the air shaft 2402 may also be deviated. Furthermore, the position of the bag film may also change after passing through the first buffer mechanism 2500. Therefore, the position of the bag film edge changes, which causes the bag film sent to the folding mechanism 2600 to be out of the center of the folding plate 2607 and the bag film to be not folded in the center, affecting the bag making quality. Therefore, the improved folding mechanism 2600 can achieve the function of correcting the position of the bag film.

[0087] Please refer to further information. Figure 19 and Figure 20Specifically, the bag feeding device 3000 also includes a second bag-pulling film mechanism 3200, which plays an auxiliary pulling role in the packaging bag film. The second bag-pulling film mechanism 3200 includes a second bag-pulling film motor 3201, a third bag-pulling film roller 3202, a fourth bag-pulling film roller 3203, and a second clutch cylinder 3204. The second bag-pulling film motor 3201 drives the third bag-pulling film roller 3202 to rotate. The third bag-pulling film roller 3202 meshes with the fourth bag-pulling film roller gear 3206 through a third bag-pulling film roller gear 3205. The fourth bag-pulling film roller 3203 is mounted on a second clutch plate 3207. The cylinder 3204 is driven and connected to the second clutch plate 3207, which can pull the second clutch plate 3207 to swing, thereby driving the fourth bag-pulling film roller 3203 to disengage from the third bag-pulling film roller 3202. This allows the bag film to be packaged to pass through the gap between the third bag-pulling film roller 3202 and the fourth bag-pulling film roller 3203. After the bag film has passed through, the second clutch cylinder 3204 extends, causing the fourth bag-pulling film roller 3203 to press against the third bag-pulling film roller 3202. This causes the bag film to be packaged to move under the drive of the second bag-pulling film motor 3201. Therefore, the second bag-pulling film mechanism 3200 can provide sufficient power to transport the bag film to be packaged.

[0088] Generally, under the push of the second clutch cylinder 3204, the fourth bag pulling roller 3203 and the third bag pulling roller 3202 press against each other, so that the fourth bag pulling roller 3203 can be driven by the friction force provided by the third bag pulling roller 3202, and it is not necessary to set the third bag pulling roller gear 3205 and the fourth bag pulling roller gear 3206.

[0089] Preferably, the bag-making device 2000 further includes a second buffer mechanism 2700. The second buffer mechanism 2700 includes a pair of third buffer fixed rollers 2701 and a second buffer slide rail 2702 disposed on the main support 2001. The pair of third buffer fixed rollers 2701 are rotatably connected to the main support 2001. A second buffer slide seat 2703 is slidably connected on the second buffer slide rail 2702. A second buffer movable roller 2704 and a second buffer tension cylinder 2705 are disposed on the second buffer slide seat 2703. After the packaging bag film is sent out from the second bag-pulling mechanism 3200, it passes through the third buffer fixed rollers 2701 and the second buffer movable rollers 2704. The second buffer tension cylinder 2705 applies a tension to the second buffer movable rollers 2704 to keep the packaging bag film taut. Additionally, the second buffer mechanism 2700 may also include a second buffer position detector 2706 for detecting the position of the second buffer movable roller 2704, which works in conjunction with the second bag-pulling mechanism 3200 and the first bag-pulling mechanism 3100. In this way, when the first bag-pulling mechanism 3100 transports the bag film to be packaged to the cutting mechanism 2300, the length of the bag film buffered on the second buffer movable roller 2704 in the second buffer mechanism 2700 will decrease. When the length of the bag film buffered on the second buffer movable roller 2704 decreases to a certain length, the second buffer position detector 2706 will output a signal, and the second bag-pulling mechanism 3200 will compensate for the film pulling, maintaining sufficient length of the bag film buffered on the second buffer movable roller 2704.

[0090] Please refer to further information. Figure 22Preferably, an upper cutting blade 3208 and a lower cutting blade 3209 are provided in front of the second bag-pulling film mechanism 3200 relative to the direction of movement of the bag film to be packaged. The bag-making device 2000 also includes an edge material collection mechanism 2800, which includes an upper edge material guide ring 2801, a lower edge material guide ring 2802, an edge material buffer guide ring 2803, a total edge material guide ring 2804, an edge material collection guide ring 2805, and an edge material collection turntable 2806. The upper edge material cut by the upper cutting blade 3208 passes through the upper edge material guide ring 2801, the edge material buffer guide ring 2803, the total edge material guide ring 2804, and the edge material collection guide ring 2805 to reach the edge material collection turntable 2806. The lower edge material cut by the lower cutting blade 3209 passes through the lower edge material guide ring 2802, the upper edge material guide ring 2801, the edge material buffer guide ring 2803, the total edge material guide ring 2805, and the edge material collection turntable 2806. Ring 2804 and edge material collection guide ring 2805 reach edge material collection turntable 2806; edge material collection mechanism 2800 also includes edge material collection motor 2807 that drives edge material collection turntable 2806 to rotate, reciprocating screw 2808 that rotates together with edge material collection turntable 2806 through synchronous belt, and reciprocating nut 2809 that cooperates with reciprocating screw 2808, so that reciprocating nut 2809 can move back and forth on reciprocating screw 2808. Edge material collection guide ring 2805 is set on reciprocating nut 2809. Upper edge material and lower edge material are evenly wound back and forth on edge material collection turntable 2806 through edge material collection guide ring 2805 respectively. Edge material buffer guide ring 2803 is set on edge material buffer slide 2810. Edge material buffer slide 2810 moves up and down along edge material buffer guide rod 2811 to buffer both upper and lower edge material. As described above, after the packaging film is released from the film feeding mechanism 2400 and folded by the folding mechanism 2600, the two pieces of film attached together after folding initially achieve an alignment effect. However, there is still a misalignment of about 0.5mm. Although the error is small, it is still very obvious when you look closely. Therefore, this situation is not allowed for mask bags with high requirements. So, before the folded film enters the second film pulling mechanism 3200, the upper and lower cutting blades 3208 and 3209 are used to cut the upper and lower edges. In this way, the front and rear film are completely aligned and there is no more misalignment.

[0091] Preferably, the edge material collection mechanism 2800 further includes an edge material buffer upper limit sensor 2812 and an edge material buffer lower limit sensor 2813. When the edge material buffer guide ring 2803 is in the upper position, the edge material buffer upper limit sensor 2812 outputs a signal to control the edge material collection motor 2807 to stop driving the edge material collection turntable 2806 to collect edge material. When the edge material buffer guide ring 2803 is in the lower position, the edge material buffer upper limit sensor 2812 outputs a signal to control the edge material collection motor 2807 to drive the edge material collection turntable 2806 to collect edge material. In addition, an edge material collection guide rod 2814 can be arranged parallel to the reciprocating screw 2808 to provide better guidance for the movement of edge material, thereby enabling the aforementioned limit sensors to detect more accurately.

[0092] Please refer to further information. Figure 23 and 24 Preferably, the bag-making device 2000 further includes a punching mechanism 2900. Generally, after the side sealing is completed, an easy-tear hole needs to be punched to facilitate the tearing of the mask. Therefore, the punching mechanism 2900 is provided, and it includes an easy-tear hole upper and lower sliding base 2901, an easy-tear hole puncher 2902 fixed on the easy-tear hole upper and lower sliding base 2901, and an easy-tear hole front and rear sliding base 2903. An easy-tear hole upper and lower adjusting nut 2904 is provided on the easy-tear hole upper and lower sliding base 2901. The lower adjusting nut 2904 is sleeved on the easy-tear hole upper and lower adjusting screw 2905. One end of the easy-tear hole upper and lower adjusting screw 2905 is equipped with an easy-tear hole upper and lower adjusting handwheel 2906. More specifically, rotating the easy-tear hole upper and lower adjusting handwheel 2906 can drive the easy-tear hole upper and lower adjusting screw 2905 to rotate together. The easy-tear hole upper and lower adjusting nut 2904 sleeved on the easy-tear hole upper and lower adjusting screw 2905 can then drive the easy-tear hole upper and lower sliding seat 2901 to move in the easy-tear hole. The hole-opening adjustment guide rod 2920 slides up and down to adjust the vertical position of the easy-tear hole punch 2902. The easy-tear hole opening adjustment guide rod 2920 is fixed on the easy-tear hole front and rear slide block 2903. The easy-tear hole front and rear slide block 2903 can slide along the easy-tear hole front and rear adjustment guide rod 2924 fixed on the easy-tear hole base 2919. An easy-tear hole front and rear adjustment nut 2907 is provided on the easy-tear hole front and rear slide block 2903, and the easy-tear hole front and rear adjustment nut 2907 is sleeved on a... The easy-tear hole front and rear adjustment screw 2908 has an easy-tear hole front and rear adjustment handwheel 2909 at one end. Rotating the easy-tear hole front and rear adjustment handwheel 2909 can drive the easy-tear hole front and rear adjustment screw 2908 to rotate together. The easy-tear hole front and rear adjustment nut 2907 sleeved on it will drive the easy-tear hole front and rear slide block 2903 to slide on the easy-tear hole front and rear adjustment guide rod 2924, thereby adjusting the front and rear position of the easy-tear hole punch 2902.

[0093] Preferably, the drilling mechanism 2900 further includes an upper arc hole drill 2910 and a lower arc hole drill 2911. The lower arc hole drill 2911 is fixed on the lower arc hole upper and lower sliding base 2912. The lower arc hole upper and lower sliding base 2912 is provided with a lower arc hole upper and lower adjusting nut 2913. The lower arc hole upper and lower adjusting nut 2913 is sleeved on the lower arc hole upper and lower adjusting screw 2914. A lower arc hole upper and lower adjusting handle is installed at one end of the lower arc hole upper and lower adjusting screw 2914. The rotation of the handwheel 2915, which adjusts the lower arc hole up and down, drives the lower arc hole up and down adjusting screw 2914 to rotate together. This causes the lower arc hole up and down adjusting nut 2913, which is fitted onto the lower arc hole up and down adjusting screw 2914, to slide the lower arc hole up and down sliding block 2912 on the lower arc hole up and down adjusting guide rod 2916, thereby adjusting the up and down position of the lower arc hole punch 2911. The lower arc hole up and down adjusting guide rod 2916 is fixed to the front and rear sliding block of the arc hole. On seat 2917, the upper end of the lower arc hole adjusting guide rod 2916 is fixed with an upper arc hole seat 2918. The upper arc hole punch 2910 is fixed on the upper arc hole seat 2918. The arc hole front and rear slide 2917 can slide along the easy-tear hole front and rear adjusting guide rod 2924 fixed on the easy-tear hole base 2919. The arc hole front and rear slide 2917 is provided with an arc hole front and rear adjusting nut 2921, which is sleeved on the arc hole front and rear adjusting screw 2917. On part 22, one end of the arc-shaped hole front-to-back adjusting screw 2922 is equipped with an arc-shaped hole front-to-back adjusting handwheel 2925. Rotating the arc-shaped hole front-to-back adjusting handwheel 2925 can drive the arc-shaped hole front-to-back adjusting screw 2922 to rotate together. Thus, the arc-shaped hole front-to-back adjusting nut 2921 sleeved on it can drive the arc-shaped hole front-to-back sliding block 2917 to slide on the easy-tear hole front-to-back adjusting guide rod 2924, thereby adjusting the front and back positions of the upper arc-shaped hole punch 2910 and the lower arc-shaped hole punch 2911. In this way, for some mask bags with rounded corners, this improved punching mechanism 2900 realizes that the upper corner of the packaging bag film is punched with the arc-shaped hole punch and the lower corner is punched with the lower arc-shaped hole punch 2911. After being cut by the cutting mechanism 2300, a mask bag 5000 with four rounded corners is produced.

[0094] Preferably, a waste collection hopper 2923 is provided below each of the aforementioned easy-tear hole punchers 2902 and the aforementioned arc hole punchers to collect the waste generated during punching.

[0095] Please refer to further information. Figure 11Specifically, the bag feeding device 3000 also includes a bag receiving mechanism 3300 and a collecting belt 3400. The bag receiving mechanism 3300 includes a first steering driver 3301, a second steering driver 3302, a suction cup fixing plate 3303, and a suction cup 3304. After the suction cup 3304 picks up the mask bag 5000, the first steering driver 3301 rotates the mask bag 5000, which is in the same direction as the transport of the bag film to be packaged, by 90 degrees. The second steering driver 3302 then rotates the mask bag 5000 by another 90 degrees, and the suction cup 3304 releases the mask bag 5000 onto the collecting belt 3400. In this way, the bag film to be packaged, which contains the mask cloth, is cut into finished mask bags 5000 by the cutting mechanism 2300, received by the bag receiving mechanism 3300, placed on the collecting belt 3400, and then collected and transported by the collecting belt 3400 to the next production process.

[0096] Please refer to further information. Figure 25 Specifically, the bag-making device 2000 also includes a mask fabric detection mechanism 2010, which includes a detection base plate 2011 mounted on a sliding seat 2901 above and below the easy-tear hole, a detection pressure plate cylinder 2012, and a displacement detector 2013. The detection pressure plate 2014 is connected to the cylinder rod of the detection pressure plate cylinder 2012. A gap is left between the detection base plate 2011 and the detection pressure plate 2014 for the bag film to pass through. The detection pressure plate cylinder 2012 extends to drive the detection pressure plate 2014 to press against the detection base plate 2011. The displacement detector 2013... The detection probe is connected to the detection pressure plate 2014 to detect the movement distance of the detection pressure plate 2014. When the bag film between the detection base plate 2011 and the detection pressure plate 2014 contains a mask cloth, the movement distance of the detection pressure plate 2014 is small, and the displacement detector 2013 outputs a signal indicating the presence of a mask cloth. When the bag film between the detection base plate 2011 and the detection pressure plate 2014 does not contain a mask cloth, the movement distance of the detection pressure plate is large, and the displacement detector 2013 outputs a signal indicating the absence of a mask cloth. Therefore, it can be ensured that there are no empty bags in the finished product.
