Description

Technical Field

[0001] This utility model relates to the field of folding equipment technology, specifically to an automatic folding machine. Background Technology

[0002] In the industrial manufacturing sector, sheet metal plays a crucial role as a fundamental and widely used raw material. Sheet metals come in a wide variety of types, commonly including metal sheets (such as steel, aluminum, and copper) and non-metal sheets (such as plastic and composite materials). To ensure good structural strength and stability, the edges of the sheet metal need to be bent and folded to form specific shapes and angles, increasing its rigidity and load-bearing capacity. Simultaneously, folding also makes the product's edges smoother and rounder, preventing scratches and other injuries during use, and improving the product's safety and aesthetics.

[0003] A Chinese invention patent with publication number CN115519013B discloses a sheet metal bending device. Specifically, during the initial bending, the upper surface of the driving bending component is flush with the upper surface of the support platform. The sheet metal to be bent is placed on the support platform, and the bending line of the sheet metal is aligned with the connection line between the driving bending component and the support platform. The lower edge of the bending pressing plate in the extended state is pressed against the bending line of the sheet metal. Finally, the rotating component drives the driving bending component to rotate, thereby achieving the initial bending of the sheet metal. After bending, the edge of the sheet metal forms an angled edge.

[0004] However, in the above technical solution, after the sheet metal is milled, it needs to be removed from the milling machine and transferred to the folding machine for folding. The folding process of the milled sheet metal needs to be performed separately, which increases the processing time and reduces the overall production efficiency. Utility Model Content

[0010] Furthermore, several second drive motors and second rollers are provided, with each second drive motor connected to a corresponding second roller, and the angle between each second roller and the conveying roller track gradually decreases along the conveying direction of the conveying roller track.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0028] like Figures 1-2 As shown, an automatic folding machine according to one embodiment of this utility model includes a milling machine 1, a conveyor roller 2, and a folding device 3. The conveyor roller 2 is fixedly connected to the milling machine 1; the folding device 3 is fixedly connected to the milling machine 1 and is disposed on one side of the conveyor roller 2. The folding device 3 includes a first folding mechanism 31, a second folding mechanism 32, and a third folding mechanism 33, which are arranged sequentially along the conveying direction of the conveyor roller 2. Through the first folding mechanism 31, the second folding mechanism 32, and the third folding mechanism 33, motion folding of the sheet metal is achieved during its movement. The first folding mechanism 31 performs preliminary folding, providing a foundation for subsequent folding; the second folding mechanism 32 performs fine adjustment; and the third folding mechanism 33 performs final shaping, ensuring the folding quality. The three folding mechanisms are arranged sequentially along the conveying direction of the conveyor roller 2, and fold the sheet metal in a sequential order. Each mechanism builds upon the previous one, performing further operations to gradually complete the folding of the sheet metal, forming an orderly and continuous production process. The three folding mechanisms work together to complete the folding task of the sheet metal.

[0029] As a preferred embodiment of this utility model, it may also have the following additional technical features: the first folding mechanism 31 includes a support rod 311, a first drive motor 312, a first roller 313 and a first fixed seat 314. One end of the support rod 311 is fixedly connected to the first fixed seat 314. The output end of the first drive motor 312 passes through the first fixed seat 314 and is rotatably connected to the first roller 313. The first roller 313 is at a 90° angle to the conveying roller 2. When the first roller 313 brings the sheet into the folding area, it mainly undertakes the initial guiding and stable conveying of the sheet. At the same time, it also ensures that the sheet will be subjected to a force perpendicular to the conveying direction when it passes through the first roller 313, thereby achieving the initial folding. The end of the support rod 311 away from the first fixed seat 314 is fixedly connected to the milling equipment 1.

[0030] As a preferred embodiment of this utility model, it may also have the following additional technical features: the second folding mechanism 32 includes a first support base 321, a first mounting structure 322, a second drive motor 323, a second roller 324, and a second fixed base 325. The first support base 321 is fixedly connected to the milling equipment 1. The first mounting structure 322 is detachably connected to the first support base 321. The second fixed base 325 is fixedly connected to the first mounting structure 322. The output end of the second drive motor 323 passes through the second fixed base 325 and is rotatably connected to the second roller 324. The second roller 324 is inclined towards the conveyor roller 2, so that during the movement of the sheet, the contact between the roller and the sheet can generate a specific force direction. In conjunction with the movement of the conveyor roller 2, continuous and precise folding of the sheet can be achieved during the movement, ensuring the folding quality and consistency.

[0031] Please see Figure 3 As a preferred embodiment of this utility model, it may also have the following additional technical features: the first mounting structure 322 includes a first mounting plate 3221, a first connecting plate 3222, a first locking rod 3223, and a first locking head 3224. A first locking hole is provided on the first support base 321. One end of the first locking rod 3223 is fixedly connected to the first locking head 3224. The first connecting plate 3222 is fixedly connected to the first mounting plate 3221. The end of the first locking rod 3223 away from the first locking head 3224 passes through the first connecting plate 3222 and is threadedly connected to the first support base 321 through the first locking hole. The second drive motor 323 is fixedly connected to the first mounting plate 3221. During installation, simply passing the first locking rod 3223 through the first connecting plate 3222 and screwing it into the first locking hole of the first support base 321 quickly completes the connection between the first mounting structure 322 and the first support base 321. Using the first mounting structure 322, the second drive motor 323 and the second roller 324 can be replaced according to different folding requirements.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: Several second drive motors 323 and second rollers 324 are respectively provided, with each second drive motor 323 connected to a corresponding second roller 324. The angle between each second roller 324 and the conveying roller 2 gradually decreases along the conveying direction of the conveying roller 2. When the sheet material passes through the second folding mechanism 32, it will be subjected to forces at different angles in sequence, and the folding angle will gradually change with the conveying process. If a large-amplitude folding operation is directly performed during the sheet material folding process, it may cause problems such as deformation, uneven folding, or cracks in the sheet material. However, by gradually decreasing the angle between each second roller 324 and the conveying roller 2 along the conveying direction, the sheet material is gradually subjected to folding forces at different angles during its movement, realizing a gradual folding process. This effectively reduces stress concentration in the sheet material during the folding process, making the folding more uniform and smooth, thereby improving the folding quality and reducing the defect rate.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: the third folding mechanism 33 includes a second support base 331, a second mounting structure 332, a third drive motor 333, a third roller 334, and a third fixed base 335. The second support base 331 is fixedly connected to the milling equipment 1, the second mounting structure 332 is detachably connected to the second support base 331, and the third fixed base 335 is fixedly connected to the second mounting structure 332. The output end of the third drive motor 333 passes through the third fixed base 335 and is rotatably connected to the third roller 334. The third roller 334 is inclined towards the conveyor roller 2. During the movement of the sheet material, this inclination angle enables the contact between the roller and the sheet material to generate a specific force direction. Combined with the movement of the conveyor roller 2, it can perform efficient and precise folding operations on the sheet material. At the same time, when maintaining the third folding mechanism 33, it is not necessary to disassemble the entire equipment on a large scale. When the third drive motor 333, the third roller 334, or other related components malfunction or need to be replaced, the second mounting structure 332 can be quickly disassembled to operate the corresponding components, which greatly shortens maintenance time and costs and improves equipment availability.

[0034] Please see Figure 4As a preferred embodiment of this utility model, it may also have the following additional technical features: the second mounting structure 332 includes a second mounting plate 3321, a second connecting plate 3322, a second locking rod 3323, and a second locking head 3324. A second locking hole is provided on the second support base 331. One end of the second locking rod 3323 is fixedly connected to the second locking head 3324. The second connecting plate 3322 is fixedly connected to the second mounting plate 3321. The end of the second locking rod 3323 away from the second locking head 3324 passes through the second connecting plate 3322 and is threadedly connected to the second support base 331 through the second locking hole. A third fixing base 335 is fixedly connected to the second mounting plate 3321. During installation, simply passing the second locking rod 3323 through the second connecting plate 3322 and screwing it into the second locking hole of the second support base 331 quickly completes the connection between the second mounting structure 332 and the second support base 331. The third drive motor 333 and the third roller 334 can be replaced according to different folding requirements using the second mounting structure 332.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: a plurality of third drive motors 333 and third rollers 334 are respectively provided, each third drive motor 333 is connected to a corresponding third roller 334, and the included angle between each third roller 334 and the conveying roller 2 along the conveying direction of the conveying roller 2 gradually decreases, ensuring the continuity and stability of the folding process, so that the sheet material is gradually subjected to folding forces at different angles during the movement, realizing a progressive folding process, which can effectively reduce the stress concentration of the sheet material during the folding process, making the folding more uniform and smooth, thereby improving the folding quality and reducing the defect rate.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the angle between each second roller 324 and each third roller 334 and the conveyor roller 2 along the conveying direction of the conveyor roller 2 gradually decreases, so that the folding process is decomposed into multiple stages, each stage corresponding to a different angle between the roller and the conveyor roller 2. The sheet material is subjected to different degrees of folding action in each stage, thereby achieving gradual and fine folding. According to the characteristics of different sheet materials, by adjusting the operating parameters (such as rotation speed) of each roller, the sheet material can better adapt to the force of the equipment during the gradual folding process, thereby achieving efficient folding processing of various different sheet materials and improving the versatility and flexibility of the equipment.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the first roller 313, each of the second rollers 324 and each of the third rollers 334 are all set as rubber rollers to avoid scratches, indentations and other damage to the surface of the sheet material, and effectively protect the sheet material.

[0038] The working principle of the automatic folding machine in this embodiment is as follows: The sheet material is first milled by the milling equipment 1, and then conveyed to the first folding mechanism 31 by the conveyor roller 2. The first roller 313 bends the edge of the sheet material to 90°, completing the initial folding. As the sheet material continues to be conveyed, it enters the second folding mechanism 32, where the second roller 324 further adjusts the folding of the sheet material according to its angle with the conveyor roller 2. Finally, the sheet material reaches the third folding mechanism 33, where the third roller 334 performs the final shaping folding of the sheet material at the minimum tilt angle, ensuring that the folding angle and shape of the sheet material fully meet the design requirements.

[0039] The automatic folding machine in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the automatic folding machine can achieve high-quality folding of the board material, meet the strict requirements of different products for folding angle and shape, and effectively improve the overall production efficiency.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
