Description

Technical Field

[0001] This utility model relates to the field of bag-applying machine technology, specifically to a lifting and folding device for a bag-applying machine. Background Technology

[0002] Pocket attaching machines are key equipment in the garment, bag, and other sewing industries. Their lifting and folding mechanisms are primarily used to fold the fabric and transport it to the sewing station, automating the pocket attaching process. In existing technologies, the lifting and folding device typically uses a single large-stroke cylinder to directly drive the linkage between the folding mechanism and the horizontal feeding assembly to complete the folding height adjustment and feeding actions.

[0003] However, traditional designs have significant drawbacks. Due to the long stroke of the large-stroke cylinder, the piston has a large inertia during rapid lifting and lowering, which causes the folding mechanism to generate a violent impact when it contacts the fabric or stops. This impact not only causes deviations in folding accuracy and affects the consistency of product quality, but also exacerbates the fatigue wear of mechanical parts, shortens the service life of the equipment, and increases equipment maintenance costs and downtime.

[0004] Therefore, a lifting and folding device for a bag-applying machine is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting and folding device for a bag-applying machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting and folding device for a bag-applying machine includes a large-stroke lifting adjustment component and a folding component. A horizontal adjustment component is connected to the side of the large-stroke lifting adjustment component. The horizontal adjustment component and the folding component are adjustable. Connecting plates are connected to both ends of the horizontal adjustment component via connectors a. The folding component is located on one side of the connecting plate, and a vertical small-stroke displacement adjustment mechanism is provided between the folding component and the connecting plate. During the large-stroke descent of the large-stroke lifting adjustment component, the vertical small-stroke displacement adjustment mechanism drives the folding component to a small-stroke displacement.

[0008] As a preferred embodiment of this utility model, the vertical small stroke displacement adjustment mechanism includes a pair of vertical slide rails arranged on both sides of the connecting plate, and each vertical slide rail is provided with a vertical drive cylinder b on one side, and the vertical drive cylinder b is fixedly installed on the connecting plate, and the output end of the vertical drive cylinder b is engaged with the folding component.

[0009] As a preferred embodiment of this utility model, the vertical slide rail component includes a side slide rail b fixedly connected to the connecting plate, and a side slide seat c is slidably sleeved on the outer side of the side slide rail b. A second side plate is bolted to the side of the side slide seat c, and a connecting member b is fixedly connected to one side of the second side plate.

[0010] As a preferred embodiment of this utility model, the folding component includes a folding frame, a folding pressure plate is provided inside the folding frame, an electromagnetic adsorption component is provided inside the folding pressure plate, a plurality of adjusting cylinders are provided on the side of the folding frame, the output ends of the plurality of adjusting cylinders are arranged outward and are engaged with folding blades, and the plurality of folding blades are located on the lower surface side of the folding frame.

[0011] As a preferred embodiment of this utility model, the large stroke lifting adjustment component includes a first side plate and a sliding side plate that are slidably connected. A set of side slide rails a are fixedly connected to the inner side of the sliding side plate. A horizontal adjustment component is slidably connected between the outer sides of the two side slide rails a. A vertical drive cylinder a is installed at the upper end of the sliding side plate, and the output end of the vertical drive cylinder a is connected to the horizontal adjustment component.

[0012] The lower end of the first side plate is connected to a bottom connecting plate, and a bottom cylinder is installed at the lower end of the bottom connecting plate. A screw adjusting component is provided at the lower end of the sliding side plate, and the output end of the bottom cylinder passes through the bottom connecting plate and is engaged with the lower end of the screw adjusting component.

[0013] As a preferred embodiment of this utility model, the screw adjusting component is provided with a connecting seat, and the connecting seat is mated with a template.

[0014] As a preferred embodiment of this utility model, the horizontal adjustment component includes a mounting plate, on which a horizontal cylinder is mounted, and the output end of the horizontal cylinder is mated with a connecting plate. Horizontal slide rails are fixedly connected to both sides of the upper surface of the mounting plate, and strip-shaped bases are slidably connected to the horizontal slide rails on both sides. The strip-shaped bases are fixedly connected to the connecting piece a.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, a vertical small-stroke displacement adjustment mechanism consisting of a vertical drive cylinder b and a vertical slide rail is added between the folding component and the horizontal adjustment component. The large-stroke cylinder drives the entire mechanism to quickly rise and fall to the target position, while the small-stroke cylinder independently controls the final displacement of the folding component. This effectively buffers the motion inertia impact when the traditional single cylinder is directly driven, avoiding problems such as fabric folding wrinkles and dimensional deviations, and improving product quality consistency. The introduction of the small-stroke cylinder reduces the impact force at the moment of contact between the folding component and the fabric, reduces fatigue wear of mechanical parts such as connecting rods, bearings, and guide rails, reduces equipment failure rate, extends service life, and reduces maintenance costs and downtime.

[0017] In this invention, the vertical slide rail and the small-stroke cylinder work together to ensure the movement accuracy and stability of the folding assembly during fine-tuning. Meanwhile, the independent drive design of the horizontal adjustment assembly and the large-stroke lifting adjustment assembly further enhances the stability of the entire machine, preventing impact vibrations from interfering with other processes. The combination of the electromagnetic adsorption component, multiple sets of adjusting cylinders, and folding blades in the folding assembly can adapt to the folding requirements of different fabric specifications. The screw adjustment component and the template work together to facilitate quick replacement of the processing template, improving the equipment's adaptability to diverse production scenarios and contributing to the efficient realization of automated sewing processes.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] For an example, please refer to... Figure 1 , 2 3. A lifting and folding device for a bag-applying machine, comprising a large-stroke lifting adjustment component and a folding component. A horizontal adjustment component is connected to the side of the large-stroke lifting adjustment component. The horizontal adjustment component and the folding component are adjustable. Connecting plates 11 are connected to both ends of the horizontal adjustment component via connectors a12. The folding component is disposed on one side of the connecting plate 11. A vertical small-stroke displacement adjustment mechanism is provided between the folding component and the connecting plate 11. During the large-stroke descent of the large-stroke lifting adjustment component, the vertical small-stroke displacement adjustment mechanism drives the folding component to a small-stroke displacement.

[0028] The device consists of a large-stroke lifting adjustment component, a horizontal adjustment component, a vertical small-stroke displacement adjustment mechanism, and a folding component. Through large-stroke adjustment, small-stroke fine adjustment, and horizontal feeding, it forms three-stage actions to achieve impact-free control of the folding process.

[0029] Please refer to Figure 1 , 23. The vertical small stroke displacement adjustment mechanism includes a pair of vertical slide rails arranged on both sides of the connecting plate 11, and each vertical slide rail is provided with a vertical drive cylinder b21 on one side. The vertical drive cylinder b21 is fixedly installed on the connecting plate 11. The output end of the vertical drive cylinder b21 is engaged with the bending assembly. The vertical slide rail includes a side slide rail b20 fixedly connected to the connecting plate 11. A side slide seat c19 is slidably sleeved on the outer side of the side slide rail b20. A second side plate 18 is bolted to the side of the side slide seat c19. A connector b17 is fixedly connected to one side of the second side plate 18.

[0030] When the large stroke is driven, the output end of the vertical drive cylinder a6 is connected to the horizontal adjustment component. The side slide a4 drives the horizontal adjustment component and the material folding component to achieve a large range of lifting and lowering along the sliding side plate 2, quickly reaching the preset height. When the large stroke lifting and adjusting component drives the whole mechanism to descend to near the fabric through the large stroke cylinder, the vertical drive cylinder b21 independently drives the material folding component to descend along the side slide rail b20, and cooperates with the side slide c19 to perform small stroke fine adjustment descent.

[0031] By independently controlling the small-stroke cylinder, the hard impact of traditional large-stroke direct drive is transformed into flexible docking, avoiding the inertial impact when the folding component comes into contact with the fabric.

[0032] Please refer to Figure 1 , 2 3. The folding component includes a folding frame, inside which is a folding pressure plate. Inside the folding pressure plate is an electromagnetic adsorption component. Several adjusting cylinders are arranged on the side of the folding frame. The output ends of the several adjusting cylinders are arranged outward and are engaged with folding blades. Several folding blades are located on the lower surface side of the folding frame.

[0033] The electromagnetic adsorption component is energized to attract the fabric, ensuring no displacement of the fabric during the folding process. An adjustable cylinder drives the folding blade to rotate along the lower surface of the folding edge, achieving simultaneous folding of multiple sides of the fabric. This includes right-angle folding and bevel folding, adapting to different bag shape requirements.

[0034] The large stroke lifting adjustment assembly includes a first side plate 1 and a sliding side plate 2 that are slidably connected. A set of side slide rails a3 are fixedly connected to the inner side of the sliding side plate 2. A horizontal adjustment assembly is slidably connected between the outer sides of the two side slide rails a3. A vertical drive cylinder a6 is installed at the upper end of the sliding side plate 2, and the output end of the vertical drive cylinder a6 is connected to the horizontal adjustment assembly.

[0035] The lower end of the first side plate 1 is connected to a bottom connecting plate 8, and a bottom cylinder 9 is installed at the lower end of the bottom connecting plate 8. A screw adjustment component is provided at the lower end of the sliding side plate 2. The output end of the bottom cylinder 9 passes through the bottom connecting plate 8 and is engaged with the lower end of the screw adjustment component. A connecting seat is provided on the screw adjustment component, and a template is engaged with the connecting seat.

[0036] The bottom cylinder 9 drives the first side plate 1 and the screw adjustment component to adjust the height, thereby adjusting the height of the template. A motor is installed at the end of the screw adjustment component, which drives the lead screw to rotate, so that the connecting seat moves horizontally along the direction of the lead screw.

[0037] The horizontal adjustment assembly includes a mounting plate 5, on which a horizontal cylinder 7 is mounted, and the output end of the horizontal cylinder 7 is mated with the connecting plate 11. Horizontal slide rails 14 are fixedly connected to both sides of the upper surface of the mounting plate 5, and strip-shaped bases are slidably connected to the horizontal slide rails 14 on both sides. The strip-shaped bases are fixedly connected to the connecting piece a12.

[0038] The output end of the horizontal cylinder 7 drives the connecting plate 11 to move. The connecting plate 11 is slidably connected to the horizontal slide rail 14 to ensure overall stability during operation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
