[0001] The present invention relates to the technical field of packaging bag processing, and particularly relates to a cutting device and a usage method for producing aluminized film packaging bags. Background Art

[0002] The main manufacturing process of aluminized film packaging bags is realized through a vacuum aluminizing process. This process involves evaporating high-purity aluminum wire into a gaseous state at high temperature, and then passing a plastic film through a vacuum evaporation chamber, where gaseous aluminum molecules precipitate onto the surface of the plastic film to form a film with a bright metallic color. This process not only imparts a certain strength to the plastic packaging bag but also endows it with excellent heat insulation and heat preservation properties. Aluminized film packaging bags are a common packaging material in life and are widely used in various fields.

[0003] During the production of aluminized film packaging bags, a cutting device is usually arranged at the discharge end of a heat sealer to cut and process the connected packaging bags after heat sealing. In the process of using the existing cutting device, there are certain defects. For example, a sloping plate is inclinedly arranged at the outlet end of the existing cutting device and near the lower cutting knife to guide the cut packaging bags. The cut packaging bags slide down through the sloping plate and accumulate on the workbench. The accumulated packaging bags are relatively messy. When taking the scattered and accumulated packaging bags, it is necessary to sort out this part of the packaging bags, which is inconvenient to use. Summary of the Invention

[0013] A method for using a cutting device for producing aluminized film packaging bags is applied to the above-mentioned cutting device for producing aluminized film packaging bags. The specific operating steps of the method are: Step 1: The connected packaging bag bodies to be cut are conveyed between the upper cutting knife and the lower cutting knife, and then the packaging bag bodies stop moving. At this time, a plurality of conveying rollers receive the conveyed packaging bag bodies. Step 2: The lifting plate moves downward with the upper cutting knife, close to the lower cutting knife. During this process, the auxiliary guide assembly also moves downward with the lifting plate. When the upper cutting knife moves downward to complete the cutting of the packaging bag body, the auxiliary guide assembly contacts the upper surface of the packaging bag body after cutting. Step 3: The auxiliary guide assembly cooperates with a plurality of conveying rollers to further quickly convey the cut packaging bag body, and then the cut packaging bag body moves to the surface of the inclined receiving plate until the end of the packaging bag body contacts the baffle plate; Step four, the driving mechanism 1 causes the inclined receiving plate to move quickly in the direction away from the mounting frame 1. During the translation process, the packaging bag body on the upper surface of the inclined receiving plate is intercepted by the positioning interception component. At this time, the packaging bag body falls downward into the collecting component under the action of gravity, and the collecting component stacks and stores the fallen packaging bag bodies.

[0014] Beneficial effects of the present invention: 1. When the connected packaging bag body to be cut passes through the upper cutting knife and the lower cutting knife, the displacement of the packaging bag body stops. At this time, a plurality of conveying rollers receive the conveyed packaging bag body. Then, the lifting plate drives the upper cutting knife to move downward and approach the lower cutting knife. During this process, the auxiliary guiding and feeding assembly also moves downward together with the lifting plate. When the upper cutting knife completes the cutting of the packaging bag body, at this time, the auxiliary guiding and feeding assembly contacts the upper surface of the cut packaging bag body. Then, under the action of the auxiliary guiding and feeding assembly, in cooperation with a plurality of conveying rollers, the cut packaging bag body is further quickly conveyed. Then, the cut packaging bag body will move to the surface of the inclined receiving plate until the end of the packaging bag body contacts the baffle plate to intercept and position the packaging bag body. Then, under the action of the driving mechanism I, the inclined receiving plate is prompted to quickly move away from the mounting frame I. During the translation of the inclined receiving plate, the packaging bag body on the upper surface of the inclined receiving plate is intercepted by the provided positioning and intercepting assembly. At this time, the packaging bag body falls downward into the collecting assembly under the action of gravity, and the collecting assembly centrally stacks and stores the fallen packaging bag body. Then, the inclined receiving plate is reset under the action of the driving mechanism I to prepare to receive the next cut packaging bag body. Then, it works in a cycle according to the above working principle until a certain amount of cut packaging bag bodies are collected in the collecting assembly. Then, the stacked cut packaging bag bodies are taken away from the collecting assembly, and there is no need to sort out the stacked packaging bag bodies in this part, which is convenient to use.

[0015] 2. When the driving box drives a plurality of driving rollers to rotate rapidly to prompt the cut packaging bag body to move, under the action of the driving mechanism II and the transmission unit, each rotating shaft is prompted to rotate, thereby driving the fan blade group to rotate, generating a downward airflow. The airflow acts on the upper surface of the moving packaging bag body to prevent the packaging bag body from warping during the moving process, thereby preventing the packaging bag body from running off track and flipping during the moving process.

[0016] 3. Through the cooperation of the provided inclined guiding plate and the positioning and intercepting plate, on the one hand, it guides the packaging bag body when it moves from the conveying roller I to the inclined receiving plate. On the other hand, when the inclined receiving plate translates, the inclined guiding plate can intercept the packaging bag body on the upper surface of the inclined receiving plate to cooperate with the discharging operation of the packaging bag body.

Detailed implementation manners

[0019] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] Referring to Figures 1 - 10 , a cutting device for producing aluminized film packaging bags includes a workbench 1, the workbench 1 is arranged on one side of an external heat sealer, the upper end surface of the workbench 1 is fixed with a lower cutting knife 2, and a lifting plate 3 is arranged above the workbench 1 in a lifting and movable manner, and one side of the lower end surface of the lifting plate 3 is fixed with an upper cutting knife 4.

[0021] The peripheral heat-sealing machine is prior art, and the lower cutting knife 2 and the upper cutting knife 4 are also prior art.

[0022] After the peripheral heat-sealing machine finishes the edge-sealing process of the packaging bag body 41, the packaging bag body 41 is conveyed by feeding to between the lower cutting knife 2 and the upper cutting knife 4. Then, the upper cutting knife 4 moves towards the lower cutting knife 2 to cut the packaging bag body 41 located between the upper cutting knife 4 and the lower cutting knife 2. Then, the upper cutting knife 4 moves upward, away from the lower cutting knife 2, to avoid affecting the conveyance of the packaging bag body 41 to be cut. The lifting movement of the upper cutting knife 4 and the cooperation with the lower cutting knife 2 for the cutting process are prior art.

[0023] The conveyance of the packaging bag body 41 and the positioning of the cutting position are both prior art.

[0024] Refer to Figures 1 - 8 , two mounting brackets 5 are symmetrically fixed on the upper end face of the workbench 1. A plurality of conveying rollers 6 are rotatably arranged between the two mounting brackets 5. An auxiliary guiding and feeding assembly is arranged on the other side of the lower end face of the lifting plate 3. An inclined receiving plate 7 is movably penetrated between the two mounting brackets 5. A baffle plate 8 is fixed between the two mounting brackets 5. A driving mechanism 1 for cooperating with the inclined receiving plate 7 is arranged on one side of the mounting bracket 5. A positioning and intercepting assembly for cooperating with the inclined receiving plate 7 is arranged on the two mounting brackets 5. A collecting assembly for cooperating with the inclined receiving plate 7 is arranged on the workbench 1.

[0025] When the connected packaging bag body 41 to be cut passes through the upper cutting knife 4 and the lower cutting knife 2, the packaging bag body 41 stops moving. At this time, multiple conveying rollers 6 receive the conveyed packaging bag body 41, and then the lifting plate 3 moves downward with the upper cutting knife 4, close to the lower cutting knife 2. During this process, the auxiliary guiding component also moves downward with the lifting plate 3. When the upper cutting knife 4 moves downward to complete the cutting of the packaging bag body 41, the auxiliary guiding component contacts the upper surface of the cut packaging bag body 41. Then, under the action of the auxiliary guiding component, the multiple conveying rollers 6 cooperate to further quickly convey the cut packaging bag body 41. Then, the cut packaging bag body 41 will move to the surface of the inclined receiving plate 7 until the end of the packaging bag body 41 contacts the baffle plate 8, intercepting and positioning the packaging bag body 41. Then, under the action of the driving mechanism 1, the inclined receiving plate 7 is prompted to move quickly in the direction away from the mounting frame 5. During the translation process, the inclined receiving plate 7 intercepts the packaging bag body 41 on the upper surface of the inclined receiving plate 7 through the arranged positioning interception component. At this time, the packaging bag body 41 falls downward into the collecting component under the action of gravity, and the collecting component stacks and stores the fallen packaging bag bodies 41. Then, the inclined receiving plate 7 is reset under the action of the driving mechanism 1, and is ready to receive the next cut packaging bag body 41. Then, it works in a cycle according to the above working principle until a certain amount of cut packaging bag bodies 41 are collected in the collecting component. Then, the cut and stacked packaging bag bodies 41 can be taken out from the collecting component. There is no need to sort out the stacked packaging bag bodies 41, which is convenient to use.

[0026] Reference Figure 1 and Figure 5 A U-shaped frame 9 is fixed to the upper end surface of the workbench 1, and two cylinders 10 are fixedly installed through the upper end surface of the U-shaped frame 9. The ends of the telescopic ends of the cylinders 10 are fixedly connected to the upper end surface of the lifting plate 3. Two guide columns 11 are symmetrically fixed to the upper end surface of the lifting plate 3. The upper end of each guide column 11 movably penetrates the U-shaped frame 9. Two mounting frames 12 are also fixed to the upper end surface of the workbench 1, and a plurality of conveying rollers 13 are rotatably arranged between the two mounting frames 12.

[0027] In the initial state, the telescopic end of the cylinder 10 is in a contracted state, so that the lifting plate 3 and the upper cutting knife 4 are located away from the lower cutting knife 2 to avoid affecting the conveyance of the packaging bag body 41.

[0028] By cooperating with the second mounting frame 12 and the second conveying roller 13, preliminary auxiliary conveying is performed on the connected packaging bag bodies 41 conveyed by the heat sealing machine, and the conveying guide of the connected packaging bag bodies 41 is the existing technology.

[0029] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 ,The auxiliary feeding assembly includes two first extension frames 14 which are fixed to the lower end surface of the lifting plate 3. A plurality of driving rollers 15 are rotatably arranged between the two first extension frames 14. The driving rollers 15 are located above the corresponding first conveying rollers 6. A driving box 16 for cooperating with the rotation of the plurality of driving rollers 15 is arranged on one side of the first extension frame 14. The driving box 16 is a prior art and is used to realize the rotation of the plurality of driving rollers 15, which is a conventional technical means in the art.

[0030] In the initial state, the driving rollers 15 are in a position away from the first conveying rollers 6 to avoid affecting the movement of the packaging bag body 41. When the lifting plate 3 drives the upper cutting knife 4 to move downward, the first extension frames 14 and the driving rollers 15 move downward accordingly until the outer surface of the driving rollers 15 fits onto the upper surface of the packaging bag body 41 located above the first conveying rollers 6. At this time, the upper cutting knife 4 just moves down to the cutting completion position. Then, the driving box 16 drives the plurality of driving rollers 15 to rotate quickly, driving the cut packaging bag body 41 to move, so that the packaging bag body 41 can move to the surface of the inclined receiving plate 7 until the end of the packaging bag body 41 contacts the baffle plate 8.

[0031] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 ,A second extension frame 17 is fixed to one side of each first extension frame 14.

A transmission unit for cooperating with the two rotating shafts 19 is arranged between the two second extension frames 17. A second driving mechanism for cooperating with the transmission unit is arranged between the first extension frame 14 and the second extension frame 17.

[0032] When the driving box 16 drives the plurality of driving rollers 15 to rotate quickly to drive the cut packaging bag body 41 to move, under the action of the second driving mechanism and the transmission unit, the respective rotating shafts 19 are driven to rotate, thereby driving the fan blade group 20 to rotate, generating a downward airflow. The airflow acts on the upper surface of the moving packaging bag body 41 to prevent the packaging bag body 41 from warping during movement, thereby preventing the packaging bag body 41 from deviating and flipping during movement.

[0033] Reference Figure 6 and Figure 7, the transmission unit includes a worm 21 rotatably arranged between two extension frames II 17. A worm wheel 22 is fixedly sleeved on the upper end of each rotating shaft 19. The worm wheel 22 is meshed and connected with the worm 21. The driving mechanism II includes a large pulley 23. The end of one of the driving rollers 15 rotatably penetrates through the extension frame I 14. The large pulley 23 is fixedly sleeved on the end of the corresponding driving roller 15. One end of the worm 21 rotatably penetrates through the extension frame II 17 and is fixedly sleeved with a small pulley 24. A transmission belt 25 is sleeved between the small pulley 24 and the large pulley 23.

[0034] During the rotation of the driving roller 15, it drives the large pulley 23 to rotate, drives the small pulley 24 to rotate through the transmission belt 25, thereby driving the worm 21 to rotate. The rotating worm 21 drives the worm wheel 22 to rotate, thereby driving the rotating shaft 19 and the fan blade group 20 to rotate.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 , the driving mechanism I includes an L-shaped plate 26 fixed to one side of the inclined receiving plate 7. A cylinder II 27 is fixed to one side of the mounting frame I 5. The end of the telescopic end of the cylinder II 27 is fixedly connected to the inner wall of the L-shaped plate 26.

[0036] In the initial state, the inclined receiving plate 7 is located between the two mounting frames I 5, and the telescopic end of the cylinder II 27 is in a contracted state. When it is necessary to unload the packaging bag body 41 on the inclined receiving plate 7, the telescopic end of the cylinder II 27 extends, thereby driving the L-shaped plate 26 and the inclined receiving plate 7 to translate.

[0037] Refer to Figure 1 、 Figure 3 and Figure 8 , the positioning and intercepting assembly includes two fixed seats 28. Each fixed seat 28 is fixed to the upper end surface of the corresponding mounting frame I 5. A lead screw 29 is threadedly penetrated through the side wall of each fixed seat 28. One end of the lead screw 29 is fixed with a positioning and intercepting plate 30. The other end of the lead screw 29 is fixed with a knob 31. A plurality of guide rods 32 are fixed to one side of the positioning and intercepting plate 30. One end of each guide rod 32 movably penetrates through the corresponding fixed seat 28. An inclined guide plate 33 is fixed to one side of each positioning and intercepting plate 30 close to the conveying roller I 6.

[0038] Through the cooperation of the inclined guide plate 33 and the positioning and intercepting plate 30 provided, on the one hand, it guides when the packaging bag body 41 moves from the conveying roller I 6 to the inclined receiving plate 7, and on the other hand, when the inclined receiving plate 7 translates, the inclined guide plate 33 can intercept the packaging bag body 41 located on the upper surface of the inclined receiving plate 7, and cooperate with the unloading operation of the packaging bag body 41.

[0039] By setting the lead screw 29 and the knob 31, the positions of the positioning and intercepting plate 30 and the inclined guiding plate 33 can be adjusted, so as to be applicable to packaging bag bodies 41 of different specifications and sizes.

[0040] Refer to Figure 1 , Figure 3 , Figure 9 and Figure 10 , the collection assembly includes a collection box 34 placed on the upper end surface of the workbench 1. A side through groove 35 is formed on one side of the collection box 34. A sunken groove 36 is formed on the upper end surface of the workbench 1.

A plurality of ventilation grooves 39 are formed through the side wall of the side baffle 37. A limiting unit is arranged between the side baffle 37 and the material blocking plate 8.

[0041] The specification of the collection box 34 matches the size of the packaging bag body 41, so that the packaging bag body 41 can move downward along the inner wall of the packaging bag body 41.

[0042] The collection box 34 has a certain weight, and the collection box 34 will not move during the use process and the process of taking the packaging bag body 41.

[0043] The determination of the position of the collection box 34, and when replacing the collection box 34 of different specifications and sizes that cooperate with the packaging bag body 41, it can be adjusted according to the two positioning and intercepting plates 30. This part of the content is the prior art.

[0044] In other embodiments, a positioning component can also be set to cooperate with the placement of the collection box 34.

[0045] In the working state, the side baffle 37 is located on one side of the collection box 34 to block the side through groove 35, so as to prevent the packaging bag body 41 from floating out of the collection box 34 during the falling process. The packaging bag body 41 falling from the inclined receiving plate 7 falls into the collection box 34 under the action of gravity. Through the arranged ventilation grooves 39, on the one hand, the pressure balance in the collection box 34 is ensured to avoid affecting the falling of the packaging bag body 41, and on the other hand, it is convenient for the staff to observe the situation in the collection box 34. When a certain number of packaging bag bodies 41 are stacked in the collection box 34, the side baffle 37 is pulled downward through the convex block 38 to release the blocking of the side through groove 35 by the side baffle 37, which is convenient for the staff to take the packaging bag bodies 41 stacked in the collection box 34.

[0046] Refer to Figure 1 and Figure 10 , the limiting unit includes a plurality of insertion and engagement posts 40 fixed on the upper end of the side baffle 37, and a plurality of insertion and engagement slots for cooperating with the corresponding insertion and engagement posts 40 are formed at the lower end of the material blocking plate 8.

[0047] In the working state, the insertion card post 40 is engaged in the insertion card slot, thereby limiting and fixing the side baffle 37.

[0048] A method for using a cutting device for producing aluminized film packaging bags, which is applied to the cutting device for producing aluminized film packaging bags described above. The specific operating steps of this method are as follows: Step 1: The bag body 41 of the packaging bags connected together to be cut is conveyed between the upper cutting knife 4 and the lower cutting knife 2, and then the bag body 41 stops moving. At this time, multiple first conveying rollers 6 receive the conveyed bag body 41. Step 2: The lifting plate 3 drives the upper cutting knife 4 to move downward, approaching the lower cutting knife 2. During this process, the auxiliary guiding and feeding component also moves downward together with the lifting plate 3. When the upper cutting knife 4 completes the cutting of the bag body 41, at this time, the auxiliary guiding and feeding component contacts the upper surface of the cut bag body 41. Step 3: The auxiliary guiding and feeding component cooperates with multiple first conveying rollers 6 to further quickly convey the cut bag body 41, and then the cut bag body 41 will move to the surface of the inclined receiving plate 7 until the end of the bag body 41 contacts the baffle 8. Step 4: The driving mechanism 1 causes the inclined receiving plate 7 to quickly move away from the first mounting frame 5. During the translation of the inclined receiving plate 7, the positioning and intercepting component arranged intercepts the bag body 41 on the upper surface of the inclined receiving plate 7. At this time, the bag body 41 falls downward into the collecting component under the action of gravity, and the collecting component centrally stacks and stores the fallen bag body 41.

[0049] When the present invention is in use, when the bag body 41 to be cut, which is connected together, passes through the upper cutting knife 4 and the lower cutting knife 2, the displacement of the bag body 41 stops. At this time, a plurality of first conveying rollers 6 receive the conveyed bag body 41. Then, the lifting plate 3 drives the upper cutting knife 4 to move downward and approach the lower cutting knife 2. During this process, the auxiliary guiding and conveying assembly also moves downward together with the lifting plate 3. When the upper cutting knife 4 completes the cutting of the bag body 41 after moving downward, at this time, the auxiliary guiding and conveying assembly contacts the upper surface of the cut bag body 41. Then, under the action of the auxiliary guiding and conveying assembly, in cooperation with a plurality of first conveying rollers 6, the cut bag body 41 is further quickly conveyed. Then, the cut bag body 41 will move to the surface of the inclined receiving plate 7 until the end of the bag body 41 contacts the baffle plate 8 to intercept and position the bag body 41. Then, under the action of the first driving mechanism, the inclined receiving plate 7 is driven to quickly move away from the first mounting frame 5. During the translation of the inclined receiving plate 7, the bag body 41 on the upper surface of the inclined receiving plate 7 is intercepted by the provided positioning and intercepting assembly. At this time, the bag body 41 falls downward into the collecting assembly under the action of gravity, and the collecting assembly centrally stacks and stores the fallen bag body 41. Then, the inclined receiving plate 7 is reset under the action of the first driving mechanism to prepare to receive the next cut bag body 41. Then, it works in a cycle according to the above working principle until a certain amount of cut bag bodies 41 are collected in the collecting assembly. Then, the stacked cut bag bodies 41 are taken away from the collecting assembly, and there is no need to sort out the stacked bag bodies 41 in this part, which is convenient to use; In the initial state, the driving roller 15 is located away from the first conveying roller 6 to avoid affecting the movement of the bag body 41. When the lifting plate 3 drives the upper cutting knife 4 to move downward, the first extension frame 14 and the driving roller 15 move downward together until the outer surface of the driving roller 15 fits onto the upper surface of the bag body 41 located above the first conveying roller 6. At this time, the upper cutting knife 4 just moves downward to the cutting completion position. Then, the driving box 16 drives a plurality of driving rollers 15 to rotate quickly to drive the cut bag body 41 to move, so that the bag body 41 can move to the surface of the inclined receiving plate 7 until the end of the bag body 41 contacts the baffle plate 8; When the driving box 16 drives a plurality of driving rollers 15 to rotate quickly to drive the cut bag body 41 to move, under the action of the second driving mechanism and the transmission unit, each rotating shaft 19 is driven to rotate, thereby driving the fan blade group 20 to rotate to generate a downward air flow. The air flow acts on the upper surface of the moving bag body 41 to prevent the bag body 41 from warping during movement, thereby preventing the bag body 41 from deviating and flipping during movement; Through the cooperation of the arranged inclined guide plate 33 and the positioning and intercepting plate 30, on the one hand, when the packaging bag body 41 moves from the first conveying roller 6 to the inclined receiving plate 7, it conducts guiding. On the other hand, when the inclined receiving plate 7 moves horizontally, the inclined guide plate 33 can intercept the packaging bag body 41 located on the upper surface of the inclined receiving plate 7, and cooperate to perform the discharging operation of the packaging bag body 41; In the working state, the side baffle 37 is located on one side of the collection frame 34 to block the side through groove 35, so as to prevent the packaging bag body 41 from floating out of the collection frame 34 during the falling process. The packaging bag body 41 falling from the inclined receiving plate 7 falls into the collection frame 34 under the action of gravity. Through the arranged ventilation groove 39, on the one hand, it ensures the pressure balance in the collection frame 34 to avoid affecting the falling of the packaging bag body 41. On the other hand, it is convenient for the staff to observe the situation in the collection frame 34. When a certain number of packaging bag bodies 41 are stacked in the collection frame 34, the side baffle 37 is pulled downward through the raised block 38 to release the block of the side baffle 37 on the side through groove 35, which is convenient for the staff to take the packaging bag bodies 41 stacked together in the collection frame 34.
