Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and in particular to a pet gastrointestinal granule packaging machine and its usage method. Background Technology

[0002] In the pharmaceutical manufacturing process, filling machines are used to classify and package the produced drugs. Filling machines are divided into mechanical equipment and packaging equipment, and are suitable for packaging powders, medicines, etc. Granule filling machines are mechanical devices that separate and package solid granules.

[0003] Existing granule packaging machines mainly consist of a machine body, a feeding device, a moving plate, a heat-sealing plate, a tensioning wheel, and a cutting device. The working principle involves two moving plates that continuously reciprocate horizontally, driving the heat-sealing plate, cutting device, and cutting device on the moving plates to perform corresponding heat-sealing, cutting, and cutting actions on the small bags. The tensioning wheel on the machine body clamps the heat-sealed bags and provides downward pulling force to move them to the next process step. However, current granule packaging machines lack a device for venting air from the bags during operation. This deficiency often causes the heat-sealed bags to expand during packaging, increasing space occupation, hindering boxing, and wasting packaging materials. Summary of the Invention

[0013] Preferably, the exhaust assembly includes a piston slidably connected inside the working tube, a sliding rod fixedly provided at the bottom of the piston, an elastic element provided between the piston and the inner wall of the working tube, the end of the sliding rod away from the piston passing through the working tube and connected to a pull rope, a drum for winding the pull rope provided on the rotating rod, the piston dividing the inner cavity of the working tube into a rod chamber and a rodless chamber, and the air guide tube connected to the rodless chamber of the working tube.

[0014] This invention also discloses a method for using a pet gastrointestinal granule dispensing machine, comprising the following steps: S1: Place the packaging film on the film feeding mechanism. The equipment body controls the operation of the film feeding mechanism. The two sides of the packaging film bend and stick to the feed pipe and are conveyed downward. The film feeding mechanism conveys the packaging film to the side sealing mechanism. The side sealing mechanism heat seals the sides of the packaging film. Then, the packaging film continues to be conveyed downward. With the help of the heat sealing component and the shearing component, the packaging film is heat sealed into a packaging bag and then cut. S2: After running for a period of time and the heat sealing and shearing work are normal, place the granules to be packaged into the hopper. The hopper will feed the granules evenly through the distribution plate and the feeding pipe. The falling granules will fall into the bottom heat-sealed and side heat-sealed half-package bags. The top half-package bags that have not yet been heat-sealed will be placed between the two positioning plates on the upper and lower sides of the sleeve. S3: Then start the drive motor to run. The output shaft of the drive motor drives the lead screw to rotate. The two sleeves on the same lead screw approach each other. The sleeves drive the positioning plate to move through the support plate and the first elastic telescopic rod. Since the first connecting plate and the second connecting plate are limited, the first elastic telescopic rod and the third elastic telescopic rod are compressed. The positioning plates on the upper and lower sides of the sleeve clamp and position the upper and lower sides of the half-packaging bag respectively. S4: As the sleeve continues to move along the screw axis, the rack plate on the support plate meshes with the driven gear on the rotating rod, the rotating rod drives the swing plate to rotate, the swing plate drives the end of the actuating plate to rotate and abut against the half-packaged bag in the clamp, the actuating plate squeezes the air in the half-packaged bag upward, and the squeezed air is discharged from the half-packaged bag through the track groove of the upper positioning plate. S5: As the swing plate continues to rotate, the first plate of the swing plate presses down on the force plate under the first connecting plate, the fourth elastic telescopic rod is compressed, the force plate drives the positioning rod away from the first connecting plate, the first connecting plate is no longer restricted, the first elastic telescopic rod pushes the first connecting plate to move towards the half-packaging bag, the heat sealing plate heat seals the upper side of the half-packaging bag, making the half-packaging bag into a complete packaging bag. As the swing plate continues to rotate, the swing plate presses down on the force plate under the second connecting plate, so that the second connecting plate is also released from restriction. The second connecting plate drives the cutter to move under the push of the third elastic telescopic rod. The cutter cuts the heat-sealed packaging bag, realizing the heat-sealing and cutting work of the granules. S6: Subsequently, the drive motor controls the lead screw to rotate in the opposite direction, causing the two sleeves on the same lead screw to move away from each other. The rack plate and the driven gear mesh in the opposite direction, and the rotating rod drives the swing plate to reset and rotate, preparing for the swing plate to drive the actuating plate to perform the exhaust work again. When the first connecting plate and the second connecting plate are reset, they press the first pressing slope of the positioning rod, and the positioning rod moves down under the force. After the positioning rod is aligned with the positioning hole, the positioning rod is re-inserted into the positioning hole under the push of the fourth elastic telescopic rod, positioning the first connecting plate and the second connecting plate. S7: Then the film conveying mechanism continues to convey the packaging film downwards, repeating steps S2-S6, to perform continuous packaging, heat sealing, and shearing of the granules.

[0015] Compared with the prior art, the present invention provides a pet gastrointestinal granule dispensing machine and its usage method, which has the following beneficial effects: 1. The pet gastrointestinal pellet dispensing machine and its usage method, through the operation of the heat sealing component driving the exhaust component, can squeeze out the air in the half-package bag before the pellet packaging bag is heat-sealed and dispensed, so as to avoid the problem of the heat-sealed small bag expanding after dispensing, increasing the space occupied, which is not conducive to boxing and causing waste of packaging materials.

[0016] 2. The pet gastrointestinal pellet dispensing machine and its usage method, when the heat sealing component is working, the rotation of the lead screw is controlled by a transmission system (rack plate + driven gear + rotating rod) to simultaneously control: exhaust toggle, air extraction piston, heat sealing / shearing unlocking. The movement of the rack plate triggers the positioning plate, heat sealing plate and cutter to contact the packaging bag formed by the packaging film in sequence, so that the semi-packaged bag is positioned and then heat sealed. After heat sealing, it is sheared, so as to realize the orderly progress of the pellet dispensing process and ensure the efficiency of pellet dispensing.

[0017] 3. The pet gastrointestinal pellet dispensing machine and its usage method utilize a drum to wind up a pull rope when the rotating rod rotates. This pull rope, through a slide rod, drives a piston to move downwards within the working tube. The working tube then draws air from the semi-packaged bag through the suction pipe. Combined with the exhaust component, this effectively removes air from the semi-packaged bag, preventing the heat-sealed bags from expanding, increasing space usage, hindering boxing, and wasting packaging materials.

[0018] 4. The pet gastrointestinal pellet dispensing machine and its operation method: When the rotating rod rotates, the pull rope is released by the drum. The piston is reset and moved downward under the elastic force of the elastic element. The working pipe discharges the internal air into the air chamber of the feeding pipe through the exhaust pipe, and the air is discharged between the outer wall of the feeding pipe and the inner wall of the packaging film through the exhaust hole. The air forms an air cushion layer between the inner wall of the packaging film and the outer wall of the feeding pipe, reducing the frictional resistance of the two in direct contact for a long time, avoiding the problem of packaging film adhesion due to heat or pressure, and ensuring the smoothness of the packaging bag feeding and conveying process; at the same time, the flowing air can accelerate local cooling and reduce the shrinkage and deformation of the heat-sealed area due to residual heat, thereby ensuring the dispensing quality.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figures 1 to 3 As shown, this embodiment proposes a pet gastrointestinal pellet dispensing machine, including a device body 1. The device body 1 is provided with a film conveying mechanism 2 and a side sealing mechanism 3 for conveying packaging film. It also includes a hopper 4 and a working shell 6. The hopper 4 is located on the top of the device body 1. A dispensing plate 401 is provided on the lower side of the hopper 4. A feeding pipe 5 that cooperates with the packaging film at the film conveying mechanism 2 is provided on the outer side of the dispensing plate 401. The working shell 6 is fixed on the front side of the device body 1. A heat sealing component for heat sealing the bottom of the packaging film and a cutting component for cutting the packaging bag are provided inside the working shell 6. An exhaust component that cooperates with the heat sealing component is provided inside the working shell 6. The packaging film is placed on the film conveying mechanism 2. The equipment body 1 controls the operation of the film conveying mechanism 2. The two sides of the packaging film are bent close to each other and attached to the feed pipe 5 and conveyed downward. The film conveying mechanism 2 conveys the packaging film to the side sealing mechanism 3. The side sealing mechanism 3 heat seals the sides of the packaging film and then continues to convey the packaging film downward. With the help of the heat sealing component and the shearing component, the packaging film is heat sealed into a packaging bag and then cut. When the heat sealing component is working, it drives the exhaust component to operate. It can squeeze out the air in the half packaging bag before the granule packaging bag is heat sealed and packaged. This avoids the problem of the heat-sealed small bag expanding after packaging, which increases the space occupied, is not conducive to boxing, and causes waste of packaging materials.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the heat sealing assembly further includes a lead screw 7 rotatably connected in the working shell 6, two sleeves 701 threadedly connected to the lead screw 7, a support plate 702 fixedly connected to the upper and lower sides of the sleeves 701, a trapezoidal plate 703 fixedly connected to the upper support plate 702, a first elastic telescopic rod 704 disposed on the trapezoidal plate 703, a first connecting plate 705 connected to the end of the first elastic telescopic rod 704 away from the trapezoidal plate 703, and a heat sealing plate 706 disposed on the first connecting plate 705. A drive motor 8 for driving the lead screw 7 to rotate is fixedly provided on the working shell 6, and the two sleeves 701 on the same lead screw 7 are either far apart from or close to each other. When the heat sealing assembly is working, the drive motor 8 is started and runs. The drive motor 8 is a servo motor. The output shaft of the drive motor 8 drives the lead screw 7 to rotate. The two sleeves 701 on the same lead screw 7 move closer to each other. The sleeves 701 drive the trapezoidal plate 703 to move through the support plate 702. The trapezoidal plate 703 drives the heat sealing plate 706 on the first connecting plate 705 to move through the first elastic telescopic rod 704, so that the two heat sealing plates 706 on both sides of the lead screw 7 move closer to each other. After the heat sealing plate 706 comes into contact with the packaging film, the bottom or top of the packaging film is heat sealed.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, a second elastic telescopic rod 9 is fixedly provided on the support plate 702, and a positioning plate 901 is fixedly provided at the end of the second elastic telescopic rod 9 away from the support plate 702. A track groove 9011 for air circulation is opened in the positioning plate 901 on the upper side of the sleeve 701. The output shaft of the drive motor 8 drives the lead screw 7 to rotate. The two sleeves 701 on the same lead screw 7 approach each other. When the sleeves 701 drive the trapezoidal plate 703 to move through the support plate 702, the support plate 702 simultaneously drives the positioning plate 901 to move using the second elastic telescopic rod 9. The positioning plate 901 is closer to the packaging film than the heat sealing plate 706, so that the positioning plate 901 first contacts the packaging film and performs a clamping action on the packaging film, avoiding the packaging film from becoming loose when the heat sealing plate 706 heat seals the packaging film, thus ensuring the granule packaging effect. It should be noted that the positioning plate 901 on the upper side of the sleeve 701 has a track groove 9011 to facilitate the discharge of air from the semi-packaged bag. The track groove 9011 should not be set as a vertical groove. When the exhaust component discharges air from the semi-packaged bag, it moves the particles, causing the particles to move out of the semi-packaged bag held by the positioning plate 901 along the vertically upward groove, thereby ensuring the quality of particle dispensing.

[0026] like Figure 6 and Figure 10 As shown, in a preferred embodiment, based on the above method, the shearing assembly further includes a third elastic telescopic rod 10 fixedly connected to the trapezoidal plate 703. The end of the third elastic telescopic rod 10 away from the trapezoidal plate 703 is connected to a second connecting plate 1001, and a cutter 1002 is fixedly provided on the second connecting plate 1001. The output shaft of the drive motor 8 drives the lead screw 7 to rotate. The two sleeves 701 on the same lead screw 7 move closer to each other. The sleeves 701 drive the trapezoidal plate 703 to move through the support plate 702. The trapezoidal plate 703 drives the cutter 1002 on the second connecting plate 1001 to move towards the packaging film through the third elastic telescopic rod 10. It should be noted that the cutter 1002 is farther away from the packaging film than the heat sealing plate 706, so that the cutter 1002 cuts the packaging film only after the heat sealing plate 706 has heat-sealed the packaging film, so as to realize the orderly progress of the granule packaging process and ensure the efficiency of granule packaging.

[0027] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in a preferred embodiment, based on the above method, the exhaust assembly further includes a rotating rod 11 rotatably connected to the connecting plate inside the working shell 6, a swing plate 111 disposed on the rotating rod 11, and a toggle plate 112 connected to the end of the swing plate 111 away from the rotating rod 11. A driven gear 113 is fixed on the rotating rod 11, and a rack plate 12 that meshes with the driven gear 113 is disposed on the support plate 702. As the lead screw 7 rotates, the positioning plates 901 on both sides of the lead screw 7 move closer to each other. The positioning plates 901 on the upper and lower sides of the sleeve 701 clamp and position the upper and lower sides of the semi-packaged bag, respectively. As the sleeve 701 continues to move along the axial direction of the lead screw 7, the rack plate 12 on the support plate 702 meshes with the driven gear 113 on the rotating rod 11. The rotating rod 11 drives the swing plate 111 to rotate. The swing plate 111 drives the actuating plate 112 at the end to rotate and abut against the clamped semi-packaged bag. The actuating plate 112 squeezes the air in the semi-packaged bag upward. The squeezed air is discharged from the semi-packaged bag through the track groove 9011 of the upper positioning plate 901, which avoids the problem of the packaged bag expanding after heat sealing, which is not conducive to boxing and causes waste of packaging materials. It should be noted that the swing plate 111 includes a first plate 1111 fixedly connected to the rotating rod 11 and a second plate 1112 fixedly connected to the toggle plate 112. The first plate 1111 and the second plate 1112 are connected by a rotating shaft, and a first torsion spring for the second plate 1112 to return to its original position is provided on the rotating shaft. The swing plate 111 consists of two plates that rotate elastically, which prevents the swing plate 111 from rigidly contacting the packaging film when rotating, thus avoiding damage to the packaging film. At the same time, the agitator plate 112 can be equipped with bristles, so that the agitator plate 112 can work with the bristles to agitate and expel the air inside the half-packaged bag.

[0028] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, a support plate 13 is further fixed inside the working shell 6. Two fourth elastic telescopic rods 131 are provided on the support plate 13. Each fourth elastic telescopic rod 131 is provided with a force plate 132 that moves against the first plate 1111. A positioning rod 133 is fixed on the force plate 132. A positioning hole 14 that cooperates with the positioning rod 133 is opened on the first connecting plate 705 and the second connecting plate 1001. A first extrusion slope is opened on the positioning rod 133. As the exhaust assembly operates, the swing plate 111 drives the actuating plate 112 to expel the air from the half-packaged bag. The swing plate 111 continues to rotate, and its first plate 1111 first presses down on the force plate 132 below the first connecting plate 705. The fourth elastic telescopic rod 131 is compressed, and the force plate 132 drives the positioning rod 133 away from the first connecting plate 705. The first connecting plate 705 is no longer restricted, and the first elastic telescopic rod 704 pushes the first connecting plate 705 towards the half-packaged bag. The heat-sealing plate 706 then... The upper side is heat-sealed to transform the semi-packaged bag into a complete packaged bag. It should be noted that a pressure sensor is installed inside the first elastic telescopic rod 704. When the heat-sealing plate 706 contacts the packaging film, the drive motor 8 automatically reduces its speed to 30%, slowing the movement of the sleeve 701 and causing the first elastic telescopic rod 704 to be slowly compressed, stabilizing the heat-sealing pressure at 0.15±0.02MPa. As the swing plate 111 continues to rotate, it presses down on the force-bearing plate 132 below the second connecting plate 1001, causing the second connecting plate 1001 to also... Once the restriction is lifted, the second connecting plate 1001 drives the cutter 1002 to move under the push of the third elastic telescopic rod 10. The cutter 1002 cuts the heat-sealed packaging bag, realizing the heat-sealing and cutting of the granules. Subsequently, the drive motor 8 controls the lead screw 7 to rotate in the opposite direction, causing the two sleeves 701 on the same lead screw 7 to move away from each other. The rack plate 12 meshes with the driven gear 113 in the opposite direction, and the rotating rod 11 drives the swing plate 111 to reset and rotate, preparing for the subsequent exhaust work of the swing plate 111 driving the actuating plate 112. The first connecting plate When 705 and the second connecting plate 1001 are reset, they press the first pressing slope of the positioning rod 133, causing the positioning rod 133 to move downward under force. After the positioning rod 133 is aligned with the positioning hole 14, the positioning rod 133 is re-inserted into the positioning hole 14 under the push of the fourth elastic telescopic rod 131, positioning the first connecting plate 705 and the second connecting plate 1001 to ensure the orderly progress of subsequent heat sealing and shearing operations. In specific applications, the rotation angle of the swing plate 111 needs to be ≥110° to complete the complete action of exhaust → heat sealing → shearing in sequence.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 11As shown, in a preferred embodiment, based on the above method, a working pipe 16 is further fixed to the outside of the equipment body 1 by a bracket. An exhaust and exhaust assembly is provided on the working pipe 16. An air guide pipe 17 is provided outside the working pipe 16. An exhaust pipe 171 and an exhaust pipe 172 are provided inside the air guide pipe 17. A one-way valve is provided in both the exhaust pipe 171 and the exhaust pipe 172. An air suction pipe 1721 is connected to the end of the exhaust pipe 172 away from the working pipe 16. The end of the air suction pipe 1721 away from the air guide pipe 17 extends downward along the feeding pipe 5. An air chamber is opened inside the feeding pipe 5. A metal sintered filter screen with a mesh size of 0.3 mm is provided at the inlet of the air chamber of the feeding pipe 5. An exhaust hole 501 communicating with the air chamber is opened on the outside of the feeding pipe 5. The end of the exhaust pipe 171 away from the working pipe 16 is connected to the air chamber through an air pipe. Furthermore, the exhaust assembly includes a piston 161 slidably connected inside the working tube 16, a sliding rod 162 fixed at the bottom of the piston 161, an elastic element 163 provided between the piston 161 and the inner wall of the working tube 16, the end of the sliding rod 162 away from the piston 161 passing through the working tube 16 and connected to a pull rope 164, a drum 165 for winding the pull rope 164 provided on the rotating rod 11, the piston 161 dividing the inner cavity of the working tube 16 into a rod chamber and a rodless chamber, and the air guide tube 17 connected to the rodless chamber of the working tube 16; When the exhaust assembly expels air from the semi-packaged bag, the rotating rod 11 rotates and uses the drum 165 to wind up the pull rope 164. This causes the pull rope 164 to drive the piston 161 downwards within the working tube 16 via the slide rod 162. The working tube 16 then draws air from the semi-packaged bag through the suction pipe 172. This, combined with the exhaust assembly's air-expelling action, effectively removes air from the semi-packaged bag, preventing the heat-sealed bag from expanding, increasing space usage, hindering boxing, and wasting packaging materials. When the exhaust assembly resets, the rotating rod 11 rotates and uses the drum 165 to release the pull rope 164. The piston 161 resets and moves downwards under the elastic force of the elastic element 163, allowing the working tube 16 to... The air inside is discharged into the air chamber of the feeding pipe 5 through the exhaust pipe 171, and then discharged between the outer wall of the feeding pipe 5 and the inner wall of the packaging film through the exhaust hole 501. The air forms an air cushion layer between the inner wall of the packaging film and the outer wall of the feeding pipe 5, reducing the frictional resistance of the two in direct contact for a long time, avoiding the problem of packaging film adhesion due to heat or pressure, and ensuring the smoothness of the packaging film feeding and conveying process; at the same time, the flowing air can accelerate local cooling and reduce the shrinkage deformation of the heat-sealed area due to residual heat, thereby ensuring the quality of dispensing; it should be noted that the elastic element 163 adopts a combination spring. When the pressure inside the packaging bag is >0.02MPa, an elastic element with a spring coefficient ≥50N / mm is required for effective air extraction; This application controls the rotational motion of the lead screw 7 simultaneously through a transmission system (rack plate 12 + driven gear 113 + rotating rod 11): exhaust toggle, suction piston 161, heat sealing / shearing unlocking. All actions are triggered by a single motor through the rack in stages, achieving a clever linkage of "one action driving three actions".

[0030] This invention also discloses a method for using a pet gastrointestinal granule dispensing machine, comprising the following steps: S1: Place the packaging film on the film conveying mechanism 2. The equipment body 1 controls the operation of the film conveying mechanism 2. The two sides of the packaging film approach each other, bend and stick to the feed pipe 5 and be conveyed downward. The film conveying mechanism 2 conveys the packaging film to the side sealing mechanism 3. The side sealing mechanism 3 heat seals the side of the packaging film. Then, the packaging film continues to be conveyed downward. With the help of the heat sealing component and the shearing component, the packaging film is heat sealed into a packaging bag and then cut. S2: After running for a period of time and the heat sealing and shearing work are normal, place the granules to be packaged into the hopper 4. The hopper 4 feeds the granules evenly through the distribution plate 401 and the feeding pipe 5. The falling granules fall into the bottom heat-sealed and side heat-sealed half-package bags. The top half-package bags that have not yet been heat-sealed are placed between the upper and lower positioning plates 901 of the sleeve 701. S3: Then start the drive motor 8 to run. The output shaft of the drive motor 8 drives the lead screw 7 to rotate. The two sleeves 701 on the same lead screw 7 approach each other. The sleeves 701 drive the positioning plate 901 to move through the support plate 702 and the first elastic telescopic rod 704. Since the first connecting plate 705 and the second connecting plate 1001 are limited, the first elastic telescopic rod 704 and the third elastic telescopic rod 10 are compressed. The positioning plates 901 on the upper and lower sides of the sleeves 701 clamp and position the upper and lower sides of the half-packaging bag respectively. S4: As the sleeve 701 continues to move along the screw 7 axis, the rack plate 12 on the support plate 702 meshes with the driven gear 113 on the rotating rod 11, and the rotating rod 11 drives the swing plate 111 to rotate. The swing plate 111 drives the end of the actuating plate 112 to rotate and abut against the half-packaged bag in the clamp. The actuating plate 112 squeezes the air in the half-packaged bag upward, and the squeezed air is discharged from the half-packaged bag through the track groove 9011 of the upper positioning plate 901. S5: As the swing plate 111 continues to rotate, the first plate 1111 of the swing plate 111 first presses down on the force plate 132 on the lower side of the first connecting plate 705, the fourth elastic telescopic rod 131 is compressed, the force plate 132 drives the positioning rod 133 away from the first connecting plate 705, the first connecting plate 705 is no longer restricted, the first elastic telescopic rod 704 pushes the first connecting plate 705 to move towards the half-packaging bag, the heat sealing plate 706 heat seals the upper side of the half-packaging bag, so that the half-packaging bag becomes a complete packaging bag. As the swing plate 111 continues to rotate, the swing plate 111 presses down on the force plate 132 on the lower side of the second connecting plate 1001, so that the second connecting plate 1001 is also released from restriction. The second connecting plate 1001 drives the cutter 1002 to move under the push of the third elastic telescopic rod 10. The cutter 1002 cuts the heat-sealed packaging bag, realizing the heat-sealing and cutting work of the particles. S6: Subsequently, the drive motor 8 controls the lead screw 7 to rotate in the opposite direction, so that the two sleeves 701 on the same lead screw 7 move away from each other, the rack plate 12 meshes with the driven gear 113 in the opposite direction, and the rotating rod 11 drives the swing plate 111 to reset and rotate, in preparation for the swing plate 111 to drive the actuating plate 112 to perform exhaust work again. When the first connecting plate 705 and the second connecting plate 1001 reset, they press the first pressing slope of the positioning rod 133, and the positioning rod 133 moves down under force. After the positioning rod 133 is aligned with the positioning hole 14, the positioning rod 133 is re-inserted into the positioning hole 14 under the push of the fourth elastic telescopic rod 131, and the first connecting plate 705 and the second connecting plate 1001 are positioned. S7: Then the film conveying mechanism 2 continues to convey the packaging film downwards, repeating steps S2-S6, to perform continuous packaging, heat sealing, and shearing of the granules.
