Description

Technical Field

[0001] This utility model relates to the field of paper bag processing technology, and in particular to a paper bag inner and outer layer synchronous folding and sealing press machine. Background Technology

[0002] Paper bags, as a common packaging material, have the advantages of being environmentally friendly and biodegradable, and are widely used in many fields such as food, gifts, and retail. The accompanying folding, sealing, and pressurizing machine acts like a behind-the-scenes "craftsman," quickly transforming flat paper bag material into exquisite and practical finished paper bags. Through precise control, the inner and outer layers of the paper bag are neatly folded according to a preset pattern, and then just the right amount of sealing and pressurizing treatment is applied, ensuring the paper bag has good sealing properties and a sturdy shape. This not only protects the contents of the bag but also enhances the overall aesthetics of the paper bag, meeting the needs of various commercial packaging.

[0003] Traditional folding and sealing presses typically have a metal frame, which is sturdy and durable enough to support the operation of all components. Their core components include a conveyor system, usually consisting of belts and rollers, responsible for steadily transporting the paper bags; a folding module using mechanical linkages, cams, and other structures to sequentially fold the sides of the paper bag; a heat-sealing device, equipped with heating elements and pressure rollers, using heat to force the sealing material to adhere to the paper bag and complete the seal; and a pressurizing section relying on cylinders or spring mechanisms to apply pressure during sealing, enhancing the sealing effect. All components work together to complete the paper bag processing procedure.

[0004] Traditional folding and sealing presses struggle to achieve cyclic folding due to limitations in their mechanical design. Their conveying, folding, sealing, and pressurizing processes are relatively fixed and unidirectional, lacking flexible feedback and reset mechanisms. Once a paper bag completes a single processing cycle, the machine cannot automatically adjust its components back to the initial folding position, limiting production efficiency and failing to meet the demands of large-scale, high-efficiency paper bag production. This is especially problematic during peak seasons, restricting company capacity, increasing manual intervention costs, and weakening market competitiveness. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a paper bag inner and outer layer synchronous folding and sealing press, which aims to improve the problem that traditional folding and sealing presses are difficult to achieve cyclic folding, resulting in limited production efficiency and inability to meet the needs of large-scale, high-efficiency paper bag production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paper bag inner and outer layer synchronous folding and sealing press machine, including a machine base, a folding component and a sealing component provided on the top of the machine base;

[0007] The folding assembly includes a fixed frame, which is fixedly connected to the top of the machine base. A motor is fixedly connected to the side wall of the fixed frame. A connecting column is fixedly connected to the output end of the motor. Multiple impact plates are fixedly connected to the outer wall of the connecting column. A connecting plate is fixedly connected inside the fixed frame. Multiple sliding shafts are slidably connected inside the connecting plate. A connecting ring is fixedly connected to the outer wall of each sliding shaft. A spring is sleeved on the outer wall of the sliding shaft. One end of the spring is fixedly connected to the bottom of the connecting ring, and the other end of the spring is fixedly connected to the inside of the fixed frame. A pressure table is fixedly connected to the bottom end of the sliding shaft.

[0008] Furthermore, the sealing assembly includes side plates, and a plurality of the side plates are symmetrically fixedly connected to the upper surface of the machine base.

[0009] Furthermore, each of the side plates has a transverse groove inside, and a gear is rotatably connected to the side wall of the side plate.

[0010] Furthermore, a second motor is fixedly connected to the side wall of the side plate, and a first gear is fixedly connected to the output end of the second motor.

[0011] Furthermore, a chain is provided on the outer wall of the gear, and the gear meshes with the chain.

[0012] Furthermore, the third gear meshes with the chain, and the side plate sidewall is rotatably connected to the second gear.

[0013] Furthermore, the second gear meshes with the chain, and a connecting member is fixedly connected to the outer wall of the chain.

[0014] Furthermore, the connector is slidably connected inside the transverse groove, and a heat sealing machine is fixedly connected to the side wall of the connector.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor first drives the connecting columns to rotate through a pair of connecting columns. Finally, the pressure table presses down on the cardboard to fold it in the template. When the connecting columns no longer exert force on the sliding shaft, the spring pushes the connecting ring to make the sliding shaft drive the pressure table to reset for the next folding step. The number of finished paper bags produced per unit time increases significantly, meeting the needs of large-scale, high-efficiency paper bag production.

[0017] 2. In this utility model, the motor 2 applies a rotational force to the gear 1, causing the gear 1 to rotate. Finally, the connecting piece on the outer wall of the chain can slide in the transverse groove inside the side plate, and drive the heat sealer on its side wall to move horizontally, thus sealing the paper bag, improving the overall production efficiency and ensuring the stable and efficient operation of the production line.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 The present invention provides an embodiment of a paper bag synchronous folding and sealing press, comprising a machine base 1, a folding component and a sealing component on the top of the machine base 1;

[0025] The folding assembly includes a fixed frame 2, which is fixedly connected to the top of the machine base 1. A motor 3 is fixedly connected to the side wall of the fixed frame 2. A connecting column 4 is fixedly connected to the output end of the motor 3. Multiple impact plates 5 are fixedly connected to the outer wall of the connecting column 4. A connecting plate 6 is fixedly connected inside the fixed frame 2. Multiple sliding shafts 7 are slidably connected inside the connecting plate 6. A connecting ring 8 is fixedly connected to the outer wall of each sliding shaft 7. A spring 9 is sleeved on the outer wall of the sliding shaft 7. One end of the spring 9 is fixedly connected to the bottom of the connecting ring 8, and the other end of the spring 9 is fixedly connected to the inside of the fixed frame 2. A pressure table 10 is fixedly connected to the bottom of the sliding shaft 7.

[0026] Specifically, when folding cardboard to make paper bags, the cardboard is placed stably on the surface of machine 1. It's important to note that machine 1 has a pre-set, precise folding template. Next, motor 3 is started. Motor 3 outputs power to connecting column 4, causing it to rotate around its axis. As connecting column 4 rotates, it further rotates the multiple closely arranged impact plates 5 on its outer wall. When an impact plate 5 touches a sliding shaft 7, the sliding shaft 7 is subjected to force and will displace vertically within the connecting plate 6. This vertical displacement of the sliding shaft 7... The linear displacement further pushes the pressure plate 10 at its bottom downwards, pressing down the cardboard placed on the template, allowing the cardboard to be precisely folded according to the shape of the template. Subsequently, when the connecting column 4 stops rotating and no longer applies force to the sliding shaft 7, the spring 9 will push the connecting ring 8 with its own elasticity, causing the sliding shaft 7 to drive the pressure plate 10 back to its initial position, ready for the next folding process. Through such a continuous and efficient operation process, the number of finished paper bags produced per unit time will increase significantly, which can fully meet the needs of large-scale and high-efficiency paper bag production.

[0027] Reference Figure 3 The sealing assembly includes side plates 11, multiple side plates 11 are symmetrically fixedly connected to the upper surface of the machine base 1, each side plate 11 has a transverse groove 12 inside, a gear 17 is rotatably connected to the side wall of the side plate 11, a motor 13 is fixedly connected to the side wall of the side plate 11, a gear 14 is fixedly connected to the output end of the motor 13, a chain 15 is provided on the outer wall of the gear 14, the gear 14 meshes with the chain 15, the gear 17 meshes with the chain 15, a gear 16 is rotatably connected to the side wall of the side plate 11, the gear 16 meshes with the chain 15, a connector 18 is fixedly connected to the outer wall of the chain 15, the connector 18 is slidably connected inside the transverse groove 12, and a heat sealer 19 is fixedly connected to the side wall of the connector 18.

[0028] Specifically, when sealing the folded paper bag, motor 2 13 is started. Motor 2 13 begins to run and applies rotational power to gear 1 14, causing gear 1 14 to rotate around its own axis. Since gear 1 14 meshes with chain 15, the rotation of gear 1 14 will push chain 15 to slide along the corresponding trajectory. During this process, gears 2 16 and 3 17, which mesh with chain 15, will also rotate due to the drive of chain 15. Their rotation further stabilizes the sliding of chain 15. The process makes the sliding of the chain 15 smoother and more stable. Subsequently, the connector 18 on the outer wall of the chain 15 slides horizontally in the transverse groove 12 inside the side plate 11 as the chain 15 slides. The sliding of the connector 18 will drive the heat sealer 19 on its side wall to move horizontally at the same time. The heat sealer 19 approaches the paper bag and squeezes the opening of the paper bag tightly, thereby sealing the paper bag. This sealing operation process is continuous and efficient, which improves the overall production efficiency and ensures that the production line can operate stably and efficiently continuously.

[0029] Working principle: When folding cardboard is required, it is placed on the surface of machine 1, which has a folding template. Motor 3 is started, and it drives the connecting column 4 to rotate. The connecting column 4 then causes multiple impact plates 5 on its outer wall to contact the sliding shaft 7. Under pressure, the sliding shaft 7 undergoes vertical displacement within the connecting plate 6, further pushing the pressure table 10 at its bottom to press the cardboard down and fold it within the template. When the connecting column 4 no longer exerts pressure on the sliding shaft 7, the spring 9 pushes the connecting ring 8, causing the sliding shaft 7 to reset the pressure table 10 for the next folding step. This significantly increases the number of finished paper bags produced per unit time, meeting the requirements for large-scale, high-efficiency production. When sealing folded paper bags is required for paper bag production, motor 2 13 is started. Motor 2 13 applies a rotational force to gear 14, causing gear 14 to rotate. Gear 14 meshes with chain 15, thus pushing chain 15 to slide. This process causes gears 2 16 and 3 17, which mesh with chain 15, to also rotate, further stabilizing the sliding process of chain 15. Subsequently, the connector 18 on the outer wall of chain 15 can slide in the transverse groove 12 inside the side plate 11, causing the heat sealer 19 on its side wall to move horizontally and seal the paper bag, improving overall production efficiency and ensuring stable and efficient operation of the production line.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
