Description

[0002] Billboards are a common advertising medium and are widely used in various places such as daily marketing, sales and exhibitions. Existing billboards are made of various materials. For example, the material of the Kabu light box is aluminum profile. During the production process, the aluminum profile needs to be rolled. At present, when rolling the aluminum profile, it is necessary to cut the aluminum profile into the required length first, and then use a three-axis rolling machine to roll it. Among them, the three-axis rolling machine can only process a section of arc in one direction at a time. When multiple sections and multi-directional arcs are required, they can only be spliced ​​later.

[0028] Example 1: Figure 1 As shown, a bidirectional rolling machine is mainly composed of a feeding component 1, a clamping component 3, a bending component 2 and a driving component 4.

[0029] Among them: Figure 2As shown, the feeding assembly 1 includes an upper plate 11, a lower plate 12, a feeding drive roller 14, a feeding active roller 15 and a feeding passive roller 16; the upper plate 11 and the lower plate 12 are connected and fixed by setting a support plate 13, and two feeding active rollers 15 and two feeding passive rollers 16 are respectively provided, and the two feeding active rollers 15 and the two feeding passive rollers 16 are arranged parallel and aligned front and back, and the feeding drive roller 14, the two feeding active rollers 15 and the two feeding passive rollers 16 are respectively installed and fixed to the upper plate 11 and the lower plate 12 through an upper bearing and a lower bearing, and the feeding drive roller 14 is arranged on the same side as the two feeding active rollers 15 and are located on a straight line; feeding synchronous pulleys 17 are respectively arranged on the feeding drive roller 14 and the two feeding active rollers 15, and the feeding synchronous pulleys 17 are connected by a feeding synchronous belt 18 for transmission.

[0030] like Figure 1 As shown, the clamping assembly 3 is disposed between the upper plate 11 and the lower plate 12, and is used to cooperate with the feeding drive roller 14 to achieve the clamping and loosening of the processed profile 5; specifically, as Figure 4 As shown, the clamping assembly 3 includes a connecting plate 32 and a clamping roller 35. The upper and lower ends of the connecting plate 32 are respectively connected to the cylinder body of the cylinder 33. The piston rods of the two cylinders 33 respectively penetrate the connecting plate 32 and are connected to the clamping fixing plate 31. The clamping fixing plate 31 is respectively connected and fixed to the upper plate 11 and the lower plate 12. The upper and lower ends of the clamping roller 35 are respectively connected to two bearing seats 34 through bearings, and the two bearing seats 34 are respectively connected and fixed to the connecting plate 32.

[0031] like Figure 3 As shown, the bending assembly 2 includes a bending drive shaft 21 connected to the upper plate 11 and the lower plate 12 through bearings, the bending drive shaft 21 passes through the upper plate 11 and the lower plate 12, and the upper and lower ends are respectively provided with active pulleys 25, the two active pulleys 25 are respectively connected to the passive pulleys 26 through synchronous belts 27, and bending fixing plates 28 are respectively installed on the two passive pulleys 26, and the two bending fixing plates 28 are connected and fixed by at least one supporting column 29, and two reverse bending rollers 23 and forward bending rollers 24 aligned front and back are connected between the two bending fixing plates 28, and the discharge gap between the reverse bending roller 23 and the forward bending roller 24 is docked with the discharge gap between the feeding passive roller 16 and the feeding active roller 15. The two bending fixing plates 28 are respectively fixed and installed via the connecting shaft 22 and the passive pulley 26 ; the reverse bending roller 23 and the forward bending roller 24 are respectively fixed and installed via the upper bearing, the lower bearing and the upper and lower bending fixing plates 28 .

[0032] like Figure 1 , 5As shown, the driving assembly 4 includes a first driving motor 45 and a second driving motor 44 . The first driving motor 45 is used to drive the feeding driving roller 14 to rotate, and the second driving motor 44 is used to drive the bending driving shaft 21 to rotate.

[0033] The forward bending roller 24 and the reverse bending roller 23 in the bidirectional rolling machine bending assembly 2 described in this embodiment can rotate clockwise and counterclockwise under the drive of the second driving motor 44, thereby realizing forward and reverse continuous rolling of the profile 5 continuously fed by the feeding assembly 1. The specific working process is as follows:

[0034] Put the profile 5 between the clamping roller 35 and the feeding drive roller 14, push it forward, and wait for the profile to be manually pushed between the two feeding active rollers 15 and the two feeding passive rollers 16, the upper and lower cylinders 33 on the connecting plate 32 extend, drive the clamping roller 35 to clamp the profile 5, and the feeding is implemented by the feeding drive roller 14 controlled by the first driving motor 45. The parallel feeding active rollers 15 and the feeding drive rollers 14 rotate synchronously to feed, so that the front end of the profile 5 exceeds the reverse bending roller 23 or the forward bending roller 24;

[0035] The second drive motor 44 controls the rotation of the bending drive shaft 21, which can then drive the two bending rollers to rotate clockwise or counterclockwise. With continuous feeding, the profile 5 can be rolled. The size of the bending roller rotation angle determines the size of the roll diameter, and whether the bending roller rotates clockwise or counterclockwise determines the direction of the roll.

[0036] Example 2: Figures 1 to 5 As shown, a bidirectional rolling machine is different from Example 1 in that the driving component 4 also includes a reducer mounting plate 41 connected to the lower plate 12 through a plurality of fixing columns 42, and two reducers 43 are arranged under the reducer mounting plate 41, and the two reducers 43 are respectively connected to the first drive motor 45 and the second drive motor 44; the output ends of the first drive motor 45 and the second drive motor 44 are respectively connected to the feeding drive roller 14 and the bending drive shaft 21 through a coupling 46.

[0037] Example 3: Figures 1 to 5 As shown, a bidirectional rolling machine is different from Example 2 in that an origin sensor trigger plate 212 is provided on the upper passive pulley 26, and the origin sensor trigger plate 212 is used to trigger an origin sensor 210 fixed on a sensor bracket 211, and the sensor bracket 211 is arranged on the upper plate 11; the origin sensor 210 is connected to the controller, and the controller is respectively connected to the first drive motor 45 and the second drive motor 44.

[0038] In the bidirectional rolling machine described in Example 3, the origin sensor 210 is used to determine the position of the bending component 2 and transmit the detected position information to the controller. The controller controls the output angle and direction of the second drive motor according to the rolling direction and rolling diameter of the required processed profile, and then controls the rotation angle and rotation direction of the bending roller to achieve elliptical equivariable diameter arc processing of the profile 5.

[0039] In summary, the bidirectional rolling machine composed of a feeding component 1, a bending component 2, a clamping component 3, and a driving component 4 described in embodiments 1 to 3 of the present invention can realize bidirectional continuous processing of positive arcs and reverse arcs of aluminum profiles, and can realize elliptical equivariable diameter arc processing under computational control as needed, overcoming the defect that conventional three-axis rolling machines can only process arcs in one direction at a time.
