Description

Technical Field

[0001] The present invention relates to the technical field of plaster packaging, and particularly to a packaging all-in-one machine for plaster production. Background Art

[0002] Plasters belong to a type of traditional Chinese medicine for external use. In ancient times, they were called thin patches. They are made by boiling vegetable oil or animal oil with medicine into a gelatinous substance and applying it on one side of cloth, paper or leather. They can be attached to the affected area for a long time and are mainly used to treat boils, reduce swelling and pain, etc.

[0003] The existing plaster packaging process includes adding fine materials, spreading, inner packaging and outer packaging. Among them, inner packaging is the process of laminating the surface of the plaster patch, and outer packaging is the process of putting the laminated plaster patch into a packaging bag.

[0004] After retrieval, a Chinese patent with the publication number CN208790049U discloses a packaging machine for plaster production. By setting an upper heat-sealing roller, a lower heat-sealing roller, an upper cutting knife roller and a lower cutting knife roller, the automatic bagging, sealing and bag-cutting processes of plaster packaging are realized. However, there are still the following problems:

[0005] 1. When the plaster patch is heat-sealed to the packaging bag, it is easy to have air residues in the packaging bag. The residual air will oxidize the medicinal ingredients in the plaster patch and breed bacteria, resulting in the contamination of the plaster, so that the plaster cannot be used;

[0006] 2. When exhausting air during the heat-sealing of the packaging bag, if the method of simultaneously heat-sealing the four sides of the pressed roll material is adopted, the air flow generated during pressing is likely to change the position of the relatively light plaster patch, so that the plaster patch is heat-sealed to the packaging bag during heat-sealing, resulting in low packaging quality of the plaster patch;

[0007] 3. After the plaster is heat-sealed, the temperature of the heat-sealed part of the packaging bag is high, which is easy to be connected to the heating part, resulting in the inability to continue discharging the packaged packaging bag, thus affecting the packaging efficiency of the plaster. Summary of the Invention

[0008] Technical Problems to be Solved

[0009] In view of the deficiencies of the prior art, the present invention provides a packaging integrated machine for plaster production, mainly to solve the problems that when the plaster patch is heat-sealed in the packaging bag, air is easily left in the packaging bag, and the remaining air will oxidize the medicinal materials in the plaster patch and breed bacteria, resulting in the contamination of the plaster, so that the plaster cannot be used. When exhausting air during heat-sealing of the packaging bag, if the method of pressing down the coil around the perimeter and heat-sealing simultaneously is adopted, the airflow generated during pressing is likely to change the position of the relatively light plaster patch, thus heat-sealing the plaster patch and the packaging bag together during heat-sealing, resulting in low packaging quality of the plaster patch; and after the plaster is heat-sealed, the temperature of the heat-sealed part of the packaging bag is high, which is easily connected to the heating part, resulting in the inability to continue exhausting the packaged packaging bag, thus affecting the packaging efficiency of the plaster.

[0022] Beneficial effects:

[0023] Compared with the prior art, the present invention provides a packaging integrated machine for producing plaster patches, which has the following beneficial effects:

[0024] 1. Through the cooperation of the feeding module, the feeding module, the top blowing module, the exhaust module and the packaging module, the present invention uses a method of sealing three sides first and then one side to heat-seal the packaging bag of the plaster patch. This can not only avoid the displacement of the plaster patch during the heat-sealing of the packaging bag, but also discharge the air in the packaging bag, which not only increases the shelf life of the plaster patch, but also improves the heat-sealing quality of the packaging bag.

[0025] 2. By providing a blocking module, the cooperation of the vision sensor with the first electric push rod and the baffle plate, the present invention realizes the adjustment of the distance between the plaster patches, thereby ensuring that the distance of each output plaster patch is fixed, avoiding the plaster patch being sealed together with the packaging bag during heat-sealing, and improving the packaging quality of the plaster patch.

[0026] 3. By providing a flattening mechanism, the cooperation of the lower pressing group and the conveyor will flatten and fit the plaster patch, avoiding the situation of warping feet and air bubbles in the inner packaging of the plaster patch, thereby performing secondary fitting on the inner packaging of the plaster patch and improving the fitting tightness of the inner packaging of the plaster patch.

[0027] 4. By providing a packaging module, the present invention realizes the packaging, bagging and opening operations of the plaster patch, integrates multiple functions into one, enables the simultaneous sealing, cutting and easy opening of the plaster patch packaging bag, and uses one power element to complete multiple work items, reducing the manufacturing cost of the device.

[0028] 5. The present invention is provided with a cutting mechanism. The lower tool rest moves upward and the upper tool rest moves downward, causing the upper tool rest to contact the lower tool rest and cut the rolled material. It can cut the rolled material immediately after the plaster patch is packaged, improving the production efficiency of the plaster patch packaging.

[0029] 6. The present invention is provided with an opening component. The upper tool rest drives the fixed frame and the tool head to move downward synchronously. At the same time, when the lower tool rest moves upward, it will squeeze the support rod, thereby pushing the support plate to rotate, enabling the tool head to insert into the notch, and then opening the easy-open opening of the packaging bag. There is no need for additional equipment for secondary processing, and the plaster patches with the outer packaging can be directly boxed, further improving the processing efficiency of the plaster patches.

[0030] 7. The present invention is provided with a top blowing module. The fan blows air through the through holes, thereby slightly blowing up the rolled material after three-side sealing, so that the rolled material is separated from the lower heating group. At the same time, the sealing edge is cooled, so that the rolled material will not adhere to the lower heating group, enabling the rolled material to move and change positions easily, and accelerating the cooling of the sealing edge, thereby reducing the cooling time of the sealing edge.

[0031] 8. The present invention is provided with a collection module. The fragments generated by the tool head cutting the packaging bag will fall into the collection box. Due to the existence of the mesh plate, the fragments will fall on the mesh plate, avoiding the phenomenon that the fragments fly randomly due to air pressure, enabling the fragments to completely fall into the collection box, and the lock can be opened as needed for cleaning the fragments.

[0032] 9. The present invention is provided with an exhaust module. When the support plate rotates, it will squeeze the pressure roller, causing the moving frame to move in the moving groove, and then squeezing and exhausting the three-side sealed packaging bag, so that the air in the three-side sealed packaging bag is discharged from the unsealed part between another three-side sealed packaging bag, thereby preventing the drug components in the plaster from being oxidized and extending the shelf life of the plaster patch.

[0050] Referring to Figures 1 - 13 , a packaging integrated machine for the production of plaster patches, comprising a frame body 1. The feeding end of the frame body 1 is provided with two feeding slots 5 of the same width. A blocking module 2 for equidistant adjustment of the plaster patches is arranged at the rear side of the feeding slot 5. A feeding module 3 for unwinding the upper and lower packaging bags is arranged at the rear side of the blocking module 2. A feeding module 8 for assisting in pushing the packaging bag roll is arranged at the rear side of the feeding module 3. A packaging module 4 for sealing and bag cutting of the upper and lower packaging bags is arranged at the rear side of the feeding module 8. A conveyor 101 for conveying the plaster patches is arranged below the feeding slot 5. A top blowing module 7 for assisting in cooling and blowing up the packaging bag is arranged between the inner walls on both sides of the frame body 1. An exhaust module 9 for exhausting the air from the incompletely sealed packaging bag is arranged at the top of the frame body 1. During use, first, the upper and lower rolls are respectively installed on the two feeding modules 3, and one end of the roll is placed into the feeding module 8. Then, the internally packaged plaster patches are placed in the feeding slot 5. The position of the plaster patches is adjusted through the cooperation of the conveyor 101 and the blocking module 2, and the plaster patches enter the middle of the upper and lower rolls through the conveyor 101 and are wrapped by the upper and lower rolls. The wrapped plaster patches are transferred to the packaging module 4 through the feeding mechanism to complete the sealing and bag cutting of the plaster patches. Before the packaging module 4 cuts the bag, the top blowing module 7 assists in blowing up the three-side sealed packaging bag, and at the same time, the exhaust module 9 discharges the air in the packaging bag. The packaging bag processed by the top blowing module 7 and the exhaust module 9 is cut to complete the outer packaging of the plaster patches.

[0051] In order to achieve the adjustment of the distance between the plaster patches, in the present invention, the blocking module 2 includes a first mounting bracket 201 fixed to the top of the frame body 1. The top of the crossbeam of the first mounting bracket 201 is fixed with a first electric push rod 202 by bolts. The movable end of the first electric push rod 202 is fixed with a baffle 203 by bolts. Two vision sensors 204 are fixed to the front and rear sides of the first mounting bracket 201 by bolts. The model of the vision sensor 204 is BSCH2BSCH1-80C-240. Both the vision sensor 204 and the first electric push rod 202 are electrically connected to an external controller, which is used to control the lifting, starting and stopping of the first electric push rod 202. A flattening mechanism for flattening the plaster patches is provided at the front end of the first mounting bracket 201. After the plaster patches are placed on the conveyor 101, the conveyor 101 drives the foremost plaster patch to move horizontally until it contacts the baffle 203. The conveyor 101 will continue to drive the remaining plaster patches to move horizontally. The distance between two plaster patches is determined by the front vision sensor 204. When the front vision sensor 204 detects that two plaster patches are at the set position, the vision sensor 204 transmits a signal to the external controller. The controller controls the first electric push rod 202 to contract, thereby driving the baffle 203 to move upward, and then enabling the foremost plaster patch to pass through the lower part of the baffle 203 and move to the feeding module 3. After the rear vision sensor 204 detects that the plaster patch is at the set position, it transmits a signal to the controller. The controller controls the first electric push rod 202 to extend, thereby moving the baffle 203 downward, so as to block the plaster patch and prevent the plaster patch in contact with the baffle 203 from continuing to move, thus ensuring that the distance between each output plaster patch is fixed, avoiding the plaster patch from being sealed together with the sealing bag during heat sealing, and improving the sealing quality of the plaster patch.

[0052] In order to flatten the plaster patches placed on the conveyor 101, in the present invention, the flattening mechanism includes two guide rods 205 slidably mounted at the front end of the first mounting frame 201. One end of each of the two guide rods 205 is fixed with a connecting frame 207 by bolts. One end of the connecting frame 207 is provided with a pressing-down group 208. Between the inner walls on both sides of the frame body 1, there is a supporting group 102. The supporting group 102 supports the lower roll material located at the front end of the feeding module 8 and simultaneously supports the plaster patches located on the lower roll material. Both the pressing-down group 208 and the supporting group 102 are non-powered conveyor belts. Between the inner walls on both sides of the frame body 1, there is a top-blowing module 7 for assisting in cooling and blowing up the packaging bags. On the top of the frame body 1, there is an exhaust module 9 for exhausting the incompletely sealed packaging bags. The top outer wall of the connecting frame 207 is fixed with a spiral spring 206 fixed to the first mounting frame 201 by bolts. When the conveyor 101 drives the plaster patches to move, the plaster patches will push down the pressing-down group 208, causing the pressing-down group 208 and the connecting frame 207 to move upward synchronously, thereby squeezing the spiral spring 206 to contract and generate elastic force. The pressing-down group 208 and the conveyor 101 cooperate to flatten and fit the plaster patches, avoiding the situation of warping feet and bubbles in the inner packaging of the plaster patches, thereby performing secondary fitting on the inner packaging of the plaster patches and improving the fitting tightness of the inner packaging of the plaster patches.

[0053] In order to realize the unwinding of the roll material of the outer packaging of the plaster patches, in the present invention, the loading module 3 includes two second mounting frames 301 respectively fixed on the upper and lower sides of the frame body 1. Between the inner walls on both sides of the second mounting frame 301, there is a rotatably connected mounting shaft 306. Both ends of the mounting shaft 306 pass through the second mounting frame 301 and are fixed with placing rollers 302 by bolts. A roll material is wound around the circumferential outer side of the placing roller 302. On the top of the second mounting frame 301, there is a power component for driving the placing roller 302 to rotate. The power component includes a first motor 303 fixed to one side of the second mounting frame 301 by bolts. The output shaft of the first motor 303 is key-connected with a first belt pulley 304. The circumferential outer side of the mounting shaft 306 is key-connected with a second belt pulley 305 that cooperates with the first belt pulley 304. Both the first belt pulley 304 and the second belt pulley 305 are synchronous belt pulleys and are driven by a synchronous belt. When the first motor 303 is started, the first motor 303 drives the first belt pulley 304 to rotate, and drives the second belt pulley 305 to rotate through the synchronous belt, thereby driving the placing roller 302 with the roll material placed thereon to rotate, and thus realizing the unwinding of the roll material.

[0054] In order to seal and cut the bag of the plaster patch, in the present invention, the packaging module 4 includes a third mounting frame 401 fixed to the top of the frame body 1. A second electric push rod 402 is fixed to the top of the third mounting frame 401 by bolts. The movable end of the second electric push rod 402 is fixed to a sliding plate 403 that slides between both sides of the third mounting frame 401 by bolts. A plurality of through holes are formed in the bottom of the sliding plate 403, and two guiding frames 404 are slidably connected in the through holes. A placing frame 406 is fixed to the bottom of the guiding frame 404 by bolts. A U-shaped frame 412 is slidably connected to one side of the placing frame 406. An arc-shaped elastic plate 423 fixed to the sliding plate 403 is bonded to the top of the U-shaped frame 412. The arc-shaped elastic plate 423 is made of an elastic material, preferably spring steel. An upper heating group 407 is provided at the bottom of the placing frame 406 and the U-shaped frame 412. A first tension spring 405 fixed to the sliding plate 403 is fixed to the inner wall of the top of the guiding frame 404 by bolts. A lower heating group 413 is provided below the placing frame 406 at the top of the frame body 1. Both the upper heating group 407 and the lower heating group 413 are composed of a U-shaped electric heating element and a straight electric heating element. Among them, the U-shaped electric heating element in the upper heating group 407 is located below the placing frame 406, and the straight electric heating element is located below the U-shaped frame 412, and the height of the placing frame 406 is lower than the height of the U-shaped frame 412. A cutting mechanism for cutting the material roll and an opening assembly for cutting the formed packaging bag are provided between the sliding plate 403 and the frame body 1. When the plaster patch wrapped by the rolled material moves between the upper heating group 407 and the lower heating group 413, the second electric push rod 402 is started. The second electric push rod 402 drives the sliding plate 403 to move downward, thereby driving the placing frame 406 and the upper heating group 407 to move downward. The U-shaped electric heating element in the upper heating group 407 and the U-shaped electric heating element of the lower heating group 413 seal three sides of the plaster patch, and the straight electric heating element seals the other side after the three sides are sealed, thereby forming a complete packaging bag. There is a time difference between the sealing of the U-shaped electric heating element and the straight electric heating element. After the U-shaped electric heating element seals three sides of the plaster patch, the packaging bag with three sides sealed is blown up by the top blowing module 7. The rolled material is driven to move by the feeding module 8, and then the plaster patch with three sides sealed is driven to move to the opening assembly. Before the opening assembly cuts the packaging bag, the straight electric heating element will first seal the other side, and then while the opening assembly cuts the packaging bag, the cutting mechanism cuts the rolled material, so that the rolled material forms separate packaging bags, realizing the sealing packaging and cutting of the plaster patch, an integrated operation, reducing labor and factory input costs, and effectively improving the processing efficiency.

[0055] In order to cut the roll material into bags, in the present invention, the cutting mechanism includes an upper knife holder 408 fixed to one side of the slide plate 403 by bolts and a lower knife holder 419 sliding between the inner walls of both sides of the frame body 1. The contact surface between the upper knife holder 408 and the lower knife holder 419 is serrated. Two sliding grooves 414 for the lower knife holder 419 to pass through are provided at the top of the frame body 1. The sliding grooves 414 are located between the U-shaped electric heating element and the straight-strip electric heating element of the lower heating group 413. A first rack 411 is fixed between the two placement racks 406 by bolts. An installation groove 417 is provided at the top of the frame body 1. A gear 418 that can mesh with the first rack 411 is rotatably connected between the inner walls of both sides of the installation groove 417. A second rack 422 that meshes with the gear 418 is fixed to the bottom inner wall of the lower knife holder 419 by bolts. During the downward movement of the slide plate 403 and the placement rack 406, the slide plate 403 will drive the upper knife holder 408 to move downward. At the same time, the downward movement of the placement rack 406 will drive the first rack 411 to move downward, so that the first rack 411 meshes with the gear 418. The placement rack 406 continues to move downward, driving the gear 418 to rotate, and then driving the second rack 422 to move upward, thereby driving the lower knife holder 419 to move upward, and further bringing the upper knife holder 408 into contact with the lower knife holder 419 to cut the roll material, which can cut the roll material immediately after the plaster patch is packaged, improving the production efficiency of the plaster patch packaging.

[0056] In order to open the easy-open opening of the packaging bag, in the present invention, the opening assembly includes a fixed frame 409 fixed to one side of the slide plate 403 by bolts. Knife heads 410 are fixed to both ends of the fixed frame 409 by bolts. A support plate 416 is rotatably connected to one side of the frame body 1. The support plate 416 is in an inclined state in the initial state and can conduct inclined guidance on the three-side sealed packaging bag conveyed, so that the plaster patch inside the package moves to the lowermost end under the action of gravity, avoiding the situation that the top blowing module 7 blows the three-side sealed packaging bag and causes the plaster patch inside to move, resulting in the plaster patch moving to the sealing position. Notches 415 matching the knife heads 410 are provided on both sides of the support plate 416. A support rod 421 rotatably connected to the support plate 416 is rotatably connected to one side of the lower knife holder 419. A folding rubber sleeve 420 is bonded between the lower knife holder 419 and the frame body 1. A collection module 6 for recycling waste materials is provided between the inner walls of both sides of the frame body 1. During the downward movement of the upper knife holder 408, the upper knife holder 408 drives the fixed frame 409 and the knife heads 410 to move downward synchronously. At the same time, the upward movement of the lower knife holder 419 will squeeze the support rod 421, and then push the support plate 416 to rotate, so that the knife heads 410 can be inserted into the notches 415, and then the easy-open opening of the packaging bag is opened.

[0057] The combined use of the opening assembly, the cutting mechanism and the upper heating group 407 and the lower heating group 413 enables the sealing, cutting and opening of the easy-open opening of the plaster patch packaging bag to be carried out simultaneously, and uses one power element to complete multiple work items, with a high degree of integration of the device.

[0058] In order to separate the coiled material with three-side sealing from the lower heating group 413, in the present invention, the top blowing module 7 includes a blower 701 fixed between the inner walls on both sides of the frame body 1. The blower 701 is a cross-flow fan. A flow guide frame 702 fixed to the frame body 1 is bolted at the air outlet of the blower 701. A plurality of through holes 703 are formed at the top of the frame body 1 at the air outlet of the flow guide frame 702, and the plurality of through holes 703 are framed by the lower heating group 413. When the blower 701 is started, the blower 701 will blow air through the through holes 703, so as to slightly lift the coiled material after three-side sealing, so that the coiled material is separated from the lower heating group 413. At the same time, the edge sealing part is cooled, so that the coiled material will not adhere to the lower heating group 413, so that the coiled material can be easily moved and transposed, and at the same time, the cooling of the edge sealing part is accelerated, thereby reducing the cooling time of the edge sealing.

[0059] In order to collect the waste generated by opening the easy-open opening, in the present invention, the collection module 6 includes a collection box 601 bolted to both sides of the frame body 1. A mesh plate 602 is rotatably connected to the bottom of the collection box 601, and the mesh plate 602 is fixed to the collection box 601 through a lock. The lock can be a buckle. When the cutter head 410 is inserted into the notch 415, the fragments generated by the cutter head 410 cutting the packaging bag will fall into the collection box 601. Due to the presence of the mesh plate 602, the fragments will fall on the mesh plate 602, avoiding the phenomenon that the fragments fly randomly due to air pressure, so that the fragments can completely fall into the collection box 601. The lock can be opened as needed for cleaning the fragments.

[0060] In order to exhaust the three-side sealed packaging bag, in the present invention, the exhaust module 9 includes a fifth mounting frame 901 fixed to the top of the frame body 1. Moving grooves are formed on multiple sides of the fifth mounting frame 901, and a moving frame 902 is slidably connected in the moving grooves. A pressure roller 903 is rotatably connected between the inner walls on both sides of the moving frame 902. There is a gap between the pressure roller 903 and the support plate 416 in the initial state, and the height of the gap is not less than the thickness of the packaged plaster patch packaging bag. A clearance cavity 904 is formed between the pressure roller 903 and the fifth mounting frame 901. When the support plate 416 rotates, the support plate 416 will drive the three-side sealed packaging bag to rotate, so that the three-side sealed packaging bag contacts the pressure roller 903 and the lowest part of the plaster patch is pressed by the pressure roller 903. When the support plate 416 continues to rotate, the support plate 416 will squeeze the pressure roller 903, so that the moving frame 902 moves in the moving groove, thereby squeezing and exhausting the three-side sealed packaging bag, so that the air in the three-side sealed packaging bag is discharged from the unsealed part between the other three-side sealed packaging bags, thereby preventing the drug components in the plaster from being oxidized and prolonging the shelf life of the plaster patch.

[0061] In order to realize the feeding of the coil material, in the present invention, the feeding module 8 includes a fourth mounting bracket 801 fixed to the top of the frame body 1. Slide frames 802 are slidably connected to both sides of the fourth mounting bracket 801. Pressing wheels 804 are provided on the inner walls of both sides of the slide frame 802. A second tension spring 803 fixed to the fourth mounting bracket 801 is bolted to the inner wall of the top of the slide frame 802. A second motor 805 is bolted to one side of the frame body 1. A connecting shaft 807 is fixed to the output shaft of the second motor 805 through a coupling. A plurality of top wheels 806 located below the pressing wheels 804 are key-connected to the outer circumference of the connecting shaft 807. The pressing wheels 804 are non-steering vertical steering wheels, with the model of TEC-230P1300M-24VS. When installing the coil material, one end of the upper and lower coil materials is clamped between the pressing wheels 804 and the top wheels 806. The second tension spring 803 can make the upper and lower coil materials fit closely, avoiding sliding between the upper and lower coil materials. At the same time, the pressing wheels 804 and the second motor 805 are started. The second motor 805 drives the connecting shaft 807 and the top wheels 806 to rotate, so that the linear speeds of the pressing wheels 804 and the top wheels 806 are the same, and the upper and lower coil materials are fed at the same time. Among them, the first motor 303, the second motor 805 and the pressing wheels 804 are all electrically connected to an external controller.

[0062] The present invention is used in the following steps:

[0063] S1: First, the upper and lower coil materials are respectively installed on the placing rollers 302 on both sides of the second mounting bracket 301, and one end of the upper and lower coil materials is clamped between the pressing wheels 804 and the top wheels 806. The second tension spring 803 can make the upper and lower coil materials fit closely. Then, the plaster patches packed in the inner package are placed on the conveyor 101 in the feeding groove 5.

[0064] S2: Start the conveyor 101. The conveyor 101 drives the foremost plaster patch to move horizontally until it contacts the baffle 203. The conveyor 101 will continue to drive the remaining plaster patches to move horizontally. The distance between two plaster patches is determined by the front visual sensor 204. After the front visual sensor 204 detects that two plaster patches are at the set position, the visual sensor 204 transmits the signal to the external controller. The controller controls the first electric push rod 202 to contract, thereby driving the baffle 203 to move upward, and then making the foremost plaster patch pass through below the baffle 203 and move between the upper and lower coil materials.

[0065] S3: After the rear visual sensor 204 detects that the plaster patch is at the set position, it transmits the signal to the controller. The controller controls the first electric push rod 202 to extend and controls the first motor 303, the second motor 805 and the pressing wheels 804 to start. The first electric push rod 202 extends to drive the baffle 203 to move downward, thereby blocking the plaster patch and making the plaster patch in contact with the baffle 203 unable to move forward, so as to ensure that the distance of each output plaster patch is fixed.

[0066] S4: After the first motor 303 starts, the first motor 303 drives the first pulley 304 to rotate, drives the second pulley 305 to rotate through the synchronous belt, thereby drives the placing roller 302 on which the coiled material is placed to rotate, and then realizes the uncoiling of the coiled material. At the same time, the second motor 805 will drive the connecting shaft 807 and the top wheel 806 to rotate, so that the linear speeds of the lower pressing wheel 804 and the top wheel 806 are the same, and at the same time feeds the upper and lower coiled materials, and then synchronously moves the plaster patch and the upper and lower coiled materials between the upper heating group 407 and the lower heating group 413;

[0067] S5: Start the second electric push rod 402. The second electric push rod 402 drives the slide plate 403 to move downward, thereby drives the placing rack 406 and the upper heating group 407 to move downward. The U-shaped electric heating element in the upper heating group 407 will first contact the coiled material, and the U-shaped electric heating elements of the lower heating group 413 seal three sides of the plaster patch. At the same time, the downward movement of the placing rack 406 will drive the first rack 411 to move downward, so that the first rack 411 meshes with the gear 418. The placing rack 406 continues to move downward, thereby drives the gear 418 to rotate, and then drives the second rack 422 to move upward, thereby drives the lower knife rest 419 to move upward. The upward movement of the lower knife rest 419 will squeeze the support rod 421, and then push the support plate 416 to rotate, so that the support plate 416 is at the same horizontal line as the bottom of the frame body 1. At this time, only the U-shaped electric heating elements between the upper heating group 407 and the lower heating group 413 seal three sides of the coiled material;

[0068] S6: When the support plate 416 rotates, it will first contact the pressing roller 903, and then continue to squeeze the pressing roller 903, so that the moving frame 902 moves in the moving groove until the pressing roller 903 is located in the gap between the upper knife rest 408 and the straight-bar electric heating element of the upper heating group 407;

[0069] S7: If there is no packaging bag after sealing three sides on the support plate 416, the second electric push rod 402 contracts, drives the slide plate 403, the placing rack 406 and the upper heating group 407 to move upward, so that the U-shaped electric heating element in the upper heating group 407 is separated from the packaging bag after sealing three sides. Start the blower 701. The blower 701 will blow the air through the through hole 703, thereby slightly blowing up the coiled material after sealing three sides, so that the coiled material is separated from the lower heating group 413, and at the same time cools the sealed edge, so that the coiled material will not adhere to the lower heating group 413.

[0070] S8: If there is a packaging bag with three sides sealed on the support plate 416, when the support plate 416 rotates, the support plate 416 will drive the packaging bag with three sides sealed to rotate, so that the packaging bag with three sides sealed contacts the pressure roller 903 and is pressed by the pressure roller 903 at the lowermost part of the plaster patch. When the support plate 416 continues to rotate, the support plate 416 will squeeze the pressure roller 903, so that the moving frame 902 moves in the moving groove, and then the packaging bag with three sides sealed is squeezed and exhausted, and the air in the packaging bag with three sides sealed is discharged from the unsealed part between another packaging bag with three sides sealed;

[0071] S9; Then the second electric push rod 402 continues to extend, which drives the slide plate 403 to continue to move downward, and then drives the U-shaped frame 412 to move downward, so that the straight strip-shaped heating element in the upper heating group 407 and the straight strip-shaped heating element in the lower heating group 413 cooperate to seal the last side of the packaging bag with three sides sealed located on the support plate 416;

[0072] S10: The slide plate 403 and the placement rack 406 continue to move downward. The slide plate 403 will drive the upper knife rest 408, the fixed rack 409 and the knife head 410 to move downward synchronously, so that the fixed rack 409, the knife head 410 and the U-shaped frame 412 are all located in the avoidance cavity 904. At the same time, the knife head 410 will first contact the sealed packaging bag, so that the knife head 410 is inserted into the insertion notch 415 to open the easy tear opening of the packaging bag. Subsequently, the upper knife rest 408 contacts the lower knife rest 419 to cut the coil material, so as to form a separate packaging bag for the edge-sealed coil material;

[0073] S11: When the easy tear opening is opened, the fragments generated by the knife head 410 cutting the packaging bag will fall into the collection box 601. Due to the existence of the mesh plate 602, the fragments will fall on the mesh plate 602, avoiding the phenomenon that the fragments fly randomly due to air pressure, so that the fragments can completely fall into the collection box 601;

[0074] S12: After the shearing is completed, the second electric push rod 402 contracts. The second electric push rod 402 will drive the slide plate 403 to move upward, so that the upper knife rest 408 and the lower knife rest 419 first disengage from contact, then the knife head 410 moves out of the notch 415, then the straight strip-shaped heating element in the upper heating group 407 disengages from the independent packaging bag, and finally the U-shaped heating element in the upper heating group 407 disengages from the packaging bag with three sides sealed. The upward movement of the slide plate 403 will drive the guide frame 404 and the placement rack 406 to move upward, which drives the first rack 411 to move upward, which drives the second rack 422 to move downward, so that the lower knife rest 419 moves downward, and then pulls one end of the support rod 421, so that the support plate 416 rotates, and then the independent packaging bag on the support plate 416 slides off, completing the independent packaging of the plaster patch;

[0075] S13: When the upper tool rest 408 is disengaged from the lower tool rest 419, the blower 701 is started. The blower 701 will blow air through the through hole 703, thereby slightly lifting the coiled material after three-side sealing, so that the coiled material is disengaged from the lower heating group 413. At the same time, the sealing edge is cooled, so that the coiled material will not adhere to the lower heating group 413, so that the coiled material can be easily moved and transposed, and at the same time, the cooling of the sealing edge is accelerated.
