Description

Technical Field

[0001] This invention relates to the field of automatic paper bag making technology, specifically to a high-speed automatic paper bag making machine and its fully automatic bag making method. Background Technology

[0002] Paper bag machines are used to produce environmentally friendly paper bags such as shopping bags, clothing bags, snack food bags, bread bags, vomit bags, and dried fruit bags. Currently, existing automatic paper bag machines do not have a pre-process dust removal function. During the unwinding process of the bag-making raw materials, dust from the air will fall. If the dust is not cleaned up, the glue will be applied unevenly later, which will affect the bonding quality and the production quality of the bags. The glue will not be strong, and the bags will be easily damaged later, making them inconvenient to use.

[0003] A search revealed a fully automatic paper bag machine with high working efficiency, disclosed in CN215473424U. This machine includes a worktable, a bag-making machine body fixedly connected to the top left side of the worktable, a top plate fixedly connected to the top of the bag-making machine body, a cylinder fixedly connected to the top right side of the top plate, a mounting base fixedly connected to the bottom of the cylinder, a hot-cutting knife fixedly connected to the bottom of the mounting base, and a controller fixedly connected to the top right side of the mounting base. This technical solution also suffers from the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed automatic paper bag machine and a fully automatic bag making method thereof, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed automatic paper bag machine, comprising a working body and an unwinding mechanism installed on the working body, the unwinding mechanism comprising a fixed plate, an unwinding assembly mounted on the fixed plate, the unwinding assembly being used to unwind the bag-making raw material, a tension control assembly being provided on the fixed plate, the tension control assembly being able to adjust the tension of the bag-making raw material while also blowing away dust on the bag-making raw material, and a drive assembly being fixedly installed on the fixed plate, the drive assembly being used to drive the internal structure of the unwinding assembly.

[0006] Optionally, the unwinding assembly is fixedly connected to the vertical plate on the fixed plate, an unwinding motor is fixedly installed on the side of the vertical plate, a drive shaft is fixedly connected to the output shaft of the unwinding motor, and an unwinding drum is movably inserted into the drive shaft.

[0007] Optionally, the unwinding assembly further includes a baffle mounted on a fixed plate, the top of the baffle being notched, and an end shaft being fixedly connected to the side of the unwinding drum, the end shaft being movably mounted within the notch.

[0008] Optionally, the tension control assembly includes a motion frame slidably connected to a fixed plate, a hollow cylinder rotatably mounted on the motion frame, a plurality of air inlets being provided on the hollow cylinder, a plurality of connecting strips being fixedly connected to the side of the hollow cylinder, and a support plate being fixedly connected to the connecting strips.

[0009] Optionally, a stabilizing block is fixedly connected to the side of the motion frame, and a stabilizing telescopic rod is fixedly connected to the top of the stabilizing block. The top end of the stabilizing telescopic rod is fixedly connected to the bottom of the fixed plate.

[0010] Optionally, the tension control assembly further includes a convex plate, on the side of which an air pump is fixedly mounted, and the air outlet of the air pump is connected to a dispersion pipe through a connecting pipe.

[0011] Optionally, a connecting pipe one is fixedly connected to the side of the hollow cylinder, and a connecting pipe two is fixedly connected to the dispersion pipe. The connecting pipe one and the connecting pipe two are connected by a telescopic pipe.

[0012] Optionally, the drive assembly includes an assembly plate fixedly connected to the bottom of the fixed plate, a hydraulic cylinder fixedly mounted on the side of the assembly plate, and a drive plate fixedly connected to the output shaft of the hydraulic cylinder.

[0013] Optionally, a hinge block one is fixedly connected to the side of the drive plate, a linkage plate is rotatably connected to the hinge block one, a hinge block two is connected to the side of the linkage plate away from the hinge block one, a driven plate is fixedly connected to the hinge block two, and the driven plate is fixedly connected to the motion frame.

[0014] A fully automated bag-making method includes the following steps: S1. The surface of the unwinding drum is pre-wound with the raw material for bag making. The unwinding drum is assembled and installed on the drive shaft. The end shaft and baffle support one side of the unwinding drum. The unwinding motor drives the unwinding drum to rotate through the drive shaft, so as to unwind the raw material for bag making. S2. Pass the bag-making material through the bottom of the first hollow cylinder, then through the bottom of the second hollow cylinder, and finally, the bag-making material enters the interior of the working body. S3. When the hydraulic cylinder works, it drives the drive plate to move. The drive plate will drive the driven plate to move through hinge block one, linkage plate and hinge block two. The driven plate will drive the motion frame to move. The support plate will support the bag making material and adjust the tension. S4. When the air pump is working, the gas is introduced into the dispersion tube through the connecting pipe. The airflow in the dispersion tube will enter the hollow cylinder through the connecting pipe 1, connecting pipe 2 and telescopic pipe. Finally, the gas will be sprayed out through the air blowing port, which can blow away the dust that falls on the bag making material. S5. The main working part is to print and emboss, apply glue, fold and shape the bag making raw materials, and cut them to a fixed length.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the cooperation of a fixed plate, a vertical plate, an unwinding motor, a drive shaft, an unwinding drum, a baffle, and an end shaft, can automatically unwind bag-making raw materials during use, resulting in high work efficiency. Furthermore, the unwinding drum can be quickly replaced by removing and installing a single mounting bolt, reducing the workload of the workers.

[0016] This invention utilizes the coordinated operation of a motion frame, a hollow cylinder, air inlets, connecting strips, support plates, stabilizing blocks, stabilizing telescopic rods, a convex plate, an air pump, a connecting pipe, a dispersing pipe, a first connecting pipe, a second connecting pipe, and a telescopic pipe. During use, the tension of the bag-making material can be adjusted, and the movement of the two motion frames is synchronized. One air inlet is positioned below the bag-making material for dust removal, while the other is positioned above it, ensuring dust removal from both sides. This prevents dust residue on the bag-making material, guaranteeing production quality and increasing work efficiency.

[0017] This invention utilizes the cooperation of an assembly plate, a hydraulic cylinder, a drive plate, a hinge block one, a linkage plate, a hinge block two, and a driven plate. During use, a single hydraulic cylinder can drive two moving frames, resulting in high synchronization between the two frames. It also saves on costs, provides smooth transmission, and is highly efficient. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 A high-speed automatic paper bag machine includes a working body 1, which is an outer shell. Inside the shell, there are integrated structures for printing and creasing, gluing and folding, shaping, and length cutting. The printing and creasing, gluing and folding, shaping, and length cutting structures are existing technologies, so they will not be described in detail. Multiple working parts are integrated and installed inside the outer shell of the working body 1, so that subsequent bag making steps are less likely to accumulate dust.

[0022] A horizontally mounted fixing plate 2 is fixedly connected to the side of the outer shell of the main body 1. During processing, the fixing plate 2 has two elongated openings and a notch formed on it. A vertically mounted vertical plate 3 is fixedly connected to the top of the fixing plate 2. An unwinding motor 4, which provides rotational driving force, is fixedly installed on the outer side of the vertical plate 3. A drive shaft 5 is fixedly connected to the output shaft of the unwinding motor 4. The end of the drive shaft 5 passes through the vertical plate 3. When the unwinding motor 4 is working, it can drive the drive shaft 5 to rotate. The side of the end of the drive shaft 5 is machined into shape. The device has a square-shaped insertion port 34, within which a square-shaped insert block 35 is movably inserted. One side of the insert block 35 extends beyond the insertion port 34 and is fixedly connected to an unwinding drum 6 as shown in the figure. The unwinding drum 6 is the component used to wind the bag-making material. The material is pre-wound on its surface before the unwinding and bag-making process can begin. The square-shaped insertion port 34 and insert block 35 allow the rotational driving force of the drive shaft 5 to be directly transmitted to the unwinding drum 6, causing the unwinding drum 6 to rotate together with the drive shaft 5. A cylindrical end shaft 8 is fixedly connected to the end face of the drum 6. A square-section track 30 is fixedly connected to a groove on the side of the fixing plate 2. A baffle 7 is slidably connected to the surface of the track 30. The top of the baffle 7 is machined with a notch to cooperate with the end shaft 8. The end shaft 8 is perfectly positioned within the notch at the top of the baffle 7. The surface of the end shaft 8 is smooth, and the friction between it and the baffle 7 is very small. In this way, the track 30 and the baffle 7 support the end shaft 8 without affecting the rotation of the unwinding drum 6. A ball bearing 36 is rotatably connected in the groove on the side of the baffle 7. The side of the ball bearing 36 is in close contact with the unwinding drum 6. The ball bearing 36 is a sphere, and it makes point contact with the side of the unwinding drum 6. This contact method results in very little friction. The baffle 7 is provided with a mounting bolt 31, which passes through the baffle 7 and is threaded onto the fixing plate 2. The fixing plate 2, the vertical plate 3, the unwinding motor 4, the drive shaft 5, the unwinding drum 6, the baffle 7, and the end shaft 8 cooperate to form the unwinding assembly, which is used to unwind the bag-making raw materials.

[0023] Four vertically extending stabilizing telescopic rods 15 are fixedly connected to the bottom of the fixed plate 2. Stabilizing blocks 14 are fixedly connected to the bottom ends of the stabilizing telescopic rods 15. Two stabilizing blocks 14 are fixedly connected by a U-shaped motion frame 9. The two motion frames 9 are identical in specifications, differing only in their initial height. The size of the motion frame 9 is adapted to the slot on the fixed plate 2, allowing the motion frame 9 to move up and down relative to the fixed plate 2. The motion frame 9 has an opening, into which a bearing 33 is installed. A hollow cylinder 10 is fixedly installed within the bearing 33. The outer ring of the bearing 33 is fixedly mounted to the motion frame 9, and the inner wall of the inner ring is mounted to the surface of the hollow cylinder 10. This arrangement of the bearing 33 allows the hollow cylinder 10 to rotate relative to the motion frame 9 without interfering with its movement. When the frame 9 undergoes displacement, in actual application, the rear end of the hollow cylinder 10 is also connected to the moving frame 9 through a shaft and bearing seat, thus ensuring the installation stability of the hollow cylinder 10. The rotating cylindrical structure is existing technology and is not explicitly shown in the attached drawings of this technical solution. Multiple elongated air inlets 11 are machined on the hollow cylinder 10. A connecting strip 12 is fixedly connected to the surface of the hollow cylinder 10 and at the gap between every two air inlets 11. A support plate 13 is fixedly connected to the side of the connecting strip 12 away from the hollow cylinder 10. The densely arranged support plates 13 constitute the component supporting the bag-making material, and there is a gap between every two adjacent support plates 13. In this way, the airflow blown out through the air inlets 11 can reach the surface of the bag-making material, thus blowing away dust.

[0024] There are two motion frames 9. One of them has a protruding plate 16 fixedly connected to its side. An air pump 17 is fixedly connected to a vertical side of the protruding plate 16. The air outlet of the air pump 17 is fixedly connected to a bent connecting pipe 18. The end of the connecting pipe 18 is fixedly connected to a dispersing pipe 19. When the air pump 17 is working, the gas will enter the dispersing pipe 19 through the connecting pipe 18. Two connecting pipes 21 are fixedly connected to the dispersing pipe 19. Each hollow cylinder 10 has a connecting pipe 20 fixedly connected to its end face. The connecting pipes 20 and 21 are connected by a telescopic pipe 22. The telescopic pipe 22 can extend and shorten, so as not to affect the relative up and down movement of the two motion frames 9. The motion frame 9, hollow cylinder 10, air inlet 11, connecting strip 12, support plate 13, stabilizing block 14, stabilizing telescopic rod 15, protruding plate 16, air pump 17, connecting pipe 18, dispersing pipe 19, connecting pipe 20, connecting pipe 21 and telescopic pipe 22 constitute the tension control assembly.

[0025] A vertically mounted assembly plate 23 is fixedly connected to the bottom of the fixed plate 2. A hydraulic cylinder 24, providing linear driving force, is fixedly mounted on one vertical side of the assembly plate 23. The output shaft of the hydraulic cylinder 24 passes through the assembly plate 23 and is connected to a drive plate 25. Two support telescopic rods 32 are fixedly connected to the side of the drive plate 25. The end of the support telescopic rod 32 away from the drive plate 25 is fixedly connected to the assembly plate 23. When the hydraulic cylinder 24 works, it can drive the drive plate 25 to move linearly. The support telescopic rods 32 are designed to support the weight of the drive plate 25 itself and the structure mounted on it without affecting the linear movement of the drive plate 25, thus preventing this weight from acting on the output shaft of the hydraulic cylinder 24 and protecting the hydraulic cylinder 24. Two hinge blocks 26 are fixedly connected to the drive plate 25. A linkage plate 27 is rotatably connected to hinge block 26. A hinge block 28 is rotatably connected to the end of the linkage plate 27 away from hinge block 26. Hinge block 26 and hinge block 28 have the same specifications. Both are composed of a U-shaped block and an internal round shaft. The linkage plate 27 and the round shaft are sleeved together. A driven plate 29 is fixedly connected to the U-shaped block of hinge block 28. The two driven plates 29 are fixedly connected to two motion frames 9 respectively. The initial heights of the motion frames 9 are different. The two driven plates 29 are also one up and one down. In this way, when the drive plate 25 moves linearly, the two motion frames 9 move in different directions. The movement of the two motion frames 9 is driven by a hydraulic cylinder 24. The movement synchronization is high. The assembly plate 23, hydraulic cylinder 24, drive plate 25, hinge block 26, linkage plate 27, hinge block 28 and driven plate 29 constitute the drive assembly.

[0026] The fixed plate 2, the unwinding assembly, the tension control assembly, and the drive assembly constitute the unwinding mechanism. This technical solution also includes a conventional controller, which is not shown in the figure. The controller is set up to achieve a higher degree of work automation.

[0027] A fully automated bag-making method includes the following steps: S1. The surface of the unwinding drum 6 is pre-wound with the raw material for bag making. The unwinding drum 6 is assembled and installed on the drive shaft 5. The end shaft 8 and the baffle 7 support one side of the unwinding drum 6. The unwinding motor 4 drives the unwinding drum 6 to rotate through the drive shaft 5, so as to unwind the raw material for bag making. S2. Pass the bag-making material through the bottom of the first hollow cylinder 10, then through the bottom of the second hollow cylinder 10, and finally, the bag-making material enters the interior of the working body 1. S3, the hydraulic cylinder 24 works, driving the drive plate 25 to move. The drive plate 25 will drive the driven plate 29 to move through the hinge block 1 26, the linkage plate 27 and the hinge block 28. The driven plate 29 will drive the motion frame 9 to move. The support plate 13 will support the bag making material and adjust the tension. S4. When the air pump 17 is working, the gas is introduced into the dispersion tube 19 through the connecting pipe 18. The airflow in the dispersion tube 19 will enter the hollow cylinder 10 through the connecting pipe 1 20, the connecting pipe 2 21 and the telescopic pipe 22. Finally, the gas will be sprayed out through the air blowing port 11, which can blow away the dust that falls on the bag making material. S5. The main working body 1 performs printing and creasing, gluing, folding and shaping, and length cutting on the bag making raw materials.

[0028] In use, the bag-making material pre-wound onto the surface of the unwinding drum 6 is pulled through from below the hollow drum 10 on the left side, and then from above the hollow drum 10 on the right side. The bag-making material is supported by the support plate 13. The hydraulic cylinder 24 operates, driving the drive plate 25 to move linearly. The force is transmitted to the motion frame 9 through the hinge block 26, the linkage plate 27, the hinge block 28, and the driven plate 29. The motion frame 9 then moves, and the stabilizing telescopic rod 15 extends or shortens to adjust the tension. The air pump 17 operates, and the gas enters the dispersion pipe 19 through the connecting pipe 18, and then sequentially enters the hollow drum 10 through the connecting pipe 21, the telescopic pipe 22, and the connecting pipe 20. Finally, the gas is ejected through the air outlet 11, which blows away the dust on the bag-making material. Afterward, the bag-making material enters the working body 1 for further processing.
