[0019] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0020] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figure 1 A preferred embodiment of the bending device with adjustable bending angle according to this application will be described in detail below. The bending device with adjustable bending angle includes a device body 10 and a bending adjustment component 20.

[0023] Specifically, the bending control assembly 20 includes a folding plate 21, at least one feed plate 22, and at least one fastening member 23. The folding plate 21 is rotatable toward the device body 10 to be connected to the feed plate 22 at a predetermined angle to the device body 10. The feed plate 22 is connected to the device body 10 in a manner perpendicular to the folding plate 21, and the feed plate 22 is also provided with an arc-shaped through groove 2201 corresponding to the folding trajectory of the folding plate 21. Furthermore, the feed plate 22 is also provided with a plurality of marker points evenly and at intervals along the forming direction of the arc-shaped through groove 2201.

[0024] The fastener 23 is provided to pass at least partially through one of the arc-shaped through slots 2201 and is connected to the folding plate 21 in a manner that moves toward the interior of the folding plate 21. The other end of the fastener 23 away from the folding plate 21 extends radially outward to form a step 231. The cross-sectional diameter of the step 231 is set to be larger than the inner diameter of the arc-shaped through slot 2201. Thus, when the fastener 23 moves, the step 231 is set to be relatively movable to move closer to and further away from the feed plate 22.

[0025] Those skilled in the art will understand that the transfer plate 22 is located between the folding plate 21 and the step 231 of the fastening member 23, so that when the step 231 moves relatively closer to the transfer plate 22, the step 231 gradually abuts against the transfer plate 22, thereby gradually fastening the folding plate 21; or when the step 231 moves relatively away from the transfer plate 22, the folding plate 21 is gradually loosened, thus enabling it to flip towards the device body 10. In other words, the fastening member 23 allows the folding plate 21 to be fastened when forming the predetermined angle with the device body 10, thereby maintaining the predetermined angle between the folding plate 21 and the device body 10 at a constant value.

[0026] Thus, when the folding plate 21 is released, it can flip towards the device body 10, causing the fastening member 23 to move with the folding plate 21 to a predetermined position in the arc-shaped through groove 2201 of the transfer plate 22. At this time, the fastening member 23 is adjusted so that the folding plate 21 is fastened and stops at a marked point near the arc-shaped through groove 2201, that is, a predetermined angle has been formed between the folding plate 21 and the device body 10.

[0027] In this way, when it is necessary to bend the heated board, one end of the board can be made to abut against the folding plate 21, and the other end of the board can be made to abut against the equipment body 10, so that the board is located between the equipment body 10 and the folding plate 21, thereby allowing the board to be bent at a predetermined angle in accordance with the predetermined angle formed by the folding plate 21 and the equipment body 10.

[0028] Specifically, in one example, such as Figure 1 As shown, the device body 10 has an abutment portion 11 on its side for bending the plate. The feed plate 22 is connected to the side of the device body 10 and is located near the abutment portion 11. The folding plate 21 is configured to be able to flip towards the abutment portion 11 along the forming direction of the arc-shaped through groove 2201 to form the predetermined angle with the abutment portion 11.

[0029] It is understood that the board can be placed between the abutment portion 11 and the folding plate 21 so that the two ends of the board can abut against the abutment portion 11 and the folding plate 21 respectively, thereby bending the board.

[0030] It is worth mentioning that the device body 10 can form a predetermined angle with the folding plate 21 at other positions for bending the plate. For example, in a modified embodiment, the device body 10 is provided with an abutment portion 11 at the top, and the feed plate 22 is correspondingly connected to the top of the device body 10 and close to the abutment portion 11. The folding plate 21 is configured to be able to flip toward the abutment portion 11 along the forming direction of the arc-shaped through groove 2201 to form the predetermined angle with the abutment portion 11, thereby bending the plate.

[0031] To enable those skilled in the art to understand this application, the following example illustrates the following: the device body 10 has an abutment portion 11 on its side for bending a plate; the feed plate 22 is connected to the side of the device body 10 and is located near the abutment portion 11; and the bending plate 21 is configured to be able to flip toward the abutment portion 11 along the forming direction of the arc-shaped through groove 2201, forming a predetermined angle with the abutment portion 11. That is, the bending device with adjustable bending angle can bend the plate at the side of the device body 10.

[0032] In a preferred embodiment, the number of the transfer plates 22 is set to two, wherein the folding plate 21 is disposed between the two transfer plates 22, and the two ends of the folding plate 21 are respectively connected to the two transfer plates 22. Correspondingly, the number of the fastening members 23 is also set to two, and the two fastening members 23 pass through the two arc-shaped through slots 2201 to connect to the two ends of the folding plate 21. In this way, the folding plate 21 can be flipped more stably toward the device body 10 and more stably fastened in the predetermined position after flipping for bending of the plate.

[0033] Preferably, the fastener 23 is implemented as a bolt, that is, the fastener 23 is connected to the folding plate 21 by means of a threaded connection.

[0034] Furthermore, the bending device with adjustable bending angle also includes a heating component 30, which is used to heat the board to be bent to facilitate bending.

[0035] Specifically, the heating assembly 30 includes a first plate 31, at least one second plate 32, a bracket 33, and at least one heating element 34. The first plate 31 is connected to the top of the bracket 33, and a heat outlet 301 is formed between the first plate 31 and the adjacent second plate 32. The bracket 33 is connected to the top of the device body 10. The heating element 34 is held below the first plate 31 and the second plate 32 at a predetermined height away from the device body 10, and each heating element 34 is configured to radiate heat towards one of the heat outlets 301.

[0036] Those skilled in the art will understand that the first plate 31 and the second plate 32 are used to support the board. When the board is placed on the first plate 31 and the second plate 32, at least a portion of the board is aligned with the heat outlet 301. Thus, when the heating element 34 generates heat, heat can flow from the heat outlet 301 to the board, so that the portion of the board aligned with the heat outlet 301 is heated, thereby facilitating subsequent bending of the board.

[0037] It should be added that, since the heating element 34 maintains a predetermined distance from the device body 10, the device body 10 is less likely to be affected by the heat emitted by the heating element 34.

[0038] Preferably, the first plate 31 and the second plate 32 are positioned at the same horizontal level, so that the plate can be directly placed on the first plate 31 and the second plate 32 and is unlikely to detach from the first plate 31 and the second plate 32 under gravity. In other words, the plate placed on the first plate 31 and the second plate 32 can be stably heated without the need for additional fixing devices.

[0039] In one embodiment, the number of second plates 32 is set to two, and the two second plates 32 are respectively located on both sides of the first plate 31 to form two heat outlets 301. Correspondingly, the number of heating elements 34 is also set to two, and the two heating elements 34 respectively emit heat toward the two heat outlets 301, so that at least two places of a single plate are heated in one heating process, thereby satisfying the requirements.

[0040] Preferably, both the first plate 31 and the second plate 32 are made of heat-insulating material to ensure that when the plates are heated, only the portion aligned with the heat outlet 301 is heated.

[0041] Furthermore, the heating assembly 30 also includes at least one driving unit 35, to which the second plate 32 is movably connected to the driving unit 35 so that the distance between the first plate 31 and the second plate 32 is adjusted, thereby adjusting the size of the heat outlet 301.

[0042] Understandably, when the board is placed on the first board 31 and the second board 32, the drive unit 35 is activated to move the second board 32, causing the second board 32 to move closer to and further away from the first board 31. This causes the heat outlet 301 to be adjusted accordingly to be smaller and larger, thereby reducing and increasing the portion of the board aligned with the heat outlet 301. In this way, the portion of the board that is heated can be reduced and increased accordingly, providing convenience for bending the board.

[0043] Preferably, the bracket 33 has at least one first channel 3301 on its top, the first channel 3301 is configured to extend in a direction parallel to the moving direction of the second plate 32, the drive unit 35 is connected to the first channel 3301, and the second plate 32 is movably connected to the top of the bracket 33.

[0044] Specifically, in one example, the number of drive units 35 is set to two, and the number of first channels 3301 is also set to two, with the two drive units 35 respectively connected to the two first channels 3301. The two ends of the second plate 32 are respectively connected to the two drive units 35, so that when the drive units 35 are activated to move the second plate 32, the second plate 32 can move more stably toward the first plate 31.

[0045] Specifically, in another example, such as Figure 1 As shown, two second plates 32 are provided, four drive units 35 are provided, and two first channels 3301 are provided. Each first channel 3301 is configured to connect two drive units 35, and the two drive units 35 connected to the same first channel 3301 are respectively connected to two second plates 32. The two ends of each second plate 32 are respectively connected to two drive units 35, so that the two second plates 32 can move stably toward the first plate 31 by means of the drive units 35.

[0046] In one embodiment, the drive unit 35 has a drive end, and the drive unit 35 is configured to drive the drive end to move in a direction parallel to the moving direction of the second plate 32. The second plate 32 is connected to the drive end of the drive unit 35, and thus, when the drive end moves, the second plate 32 is configured to move closer to and further away from the first plate 31 to adjust the size of the heat outlet 301. It is worth mentioning that, in this embodiment, the drive unit 35 is implemented to include a telescopic device, specifically a telescopic cylinder.

[0047] In another embodiment, the drive unit 35 includes a drive member 351 and a transmission member 352, wherein the drive member 351 is connected to the first channel 3301 of the bracket 33, and the drive member 351 is drivably connected to the transmission member 352, and the second plate 32 is connected to the transmission member 352, so that when the drive member 351 drives the transmission member 352, the second plate 32 is configured to move closer to and further away from the first plate 31 to adjust the size of the heat outlet 301.

[0048] Preferably, such as Figure 2As shown, the transmission component 352 includes a screw 3521 and a sliding block 3522.

The sliding block 3522 is threadedly connected to the screw 3521, and the second plate 32 is connected to the sliding block 3522. Thus, when the driving member 351 rotates the screw 3521, the sliding block 3522 is configured to move on the inner wall forming the first channel 3301, so that the second plate 32 follows the sliding block 3522 to move closer to and away from the first plate 31.

[0049] Preferably, the drive element 351 is implemented as a drive motor.

[0050] In addition, the bending device with adjustable bending angle of the board also includes at least one moving component 40, which is used to adjust the position of the heating element 34 so that the part of the board aligned with the heat outlet 301 can receive the same heat, so as to facilitate bending of the board.

[0051] Preferably, the movable component 40 is connected to the bracket 33, and the movable component 40 is drivably connected to the heating element 34 so that one of the heating elements 34 moves toward a different position of one of the heat outlets 301.

[0052] Preferably, the bracket 33 is further provided with at least one second channel 3302, the second channel 3302 is configured to extend in a direction parallel to the moving direction of the heating element 34, and the moving component 40 is connected to the second channel 3302.

[0053] It is worth mentioning that, preferably, the first channel 3301 is positioned above the second channel 3302.

[0054] Specifically, in one example, the number of the moving components 40 is set to two, and the number of the second channels 3302 is also set to two, with the two moving components 40 respectively connected to the two second channels 3302. The two ends of the heating element 34 are respectively connected to the two moving components 40, so that when the moving components 40 are activated, the heating element 34 is configured to move stably toward different positions of the heat outlet 301 in a predetermined manner to generate heat.

[0055] Specifically, in another example, such as Figure 2As shown, the number of heating elements 34 is set to two, the number of moving components 40 is set to four, and the number of second channels 3302 is set to two. Each second channel 3302 is configured to connect two moving components 40, and the two moving components 40 connected to the same second channel 3302 are respectively connected to two heating elements 34. The two ends of each heating element 34 are respectively connected to two moving components 40, so that the two heating elements 34 can move towards different positions of the two heat outlets 301 by means of the moving components 40 to generate heat.

[0056] In one embodiment, the movable component 40 has a telescopic end, and the movable component 40 is configured to drive the telescopic end to move in a direction parallel to the moving direction of the heating element 34. The heating element 34 is connected to the telescopic end of the movable component 40, and thus, when the telescopic end moves, the heating element 34 is configured to emit heat toward different positions of the heat outlet 301 in a predetermined manner to heat the plate. It is worth mentioning that, in this embodiment, the movable component 40 is implemented to include a telescopic device, specifically a telescopic cylinder.

The moving block 422 is threadedly connected to the driving rod 421, and the heating element 34 is connected to the moving block 422. When the driving member 41 rotates the driving rod 421, the moving block 422 is configured to move along the inner wall forming the second channel 3302. At this time, the heating element 34 moves with the moving block 422 toward different positions of the heat outlet 301 to generate heat.
