[0001] This utility model relates to the field of wood processing equipment technology, and in particular to a grooving device for sofa back panels. Background Technology

[0002] In the sofa manufacturing process, it is necessary to groove the back panel of the sofa. The existing technology is to first groove the back panel and then install the back panel onto the sofa. This requires a high degree of installation precision, otherwise it is easy to cause inaccurate grooving. Alternatively, the size of the groove can be increased to increase the tolerance for error, but this will result in a larger groove size or increased installation difficulty. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a sofa back panel grooving device to solve the problem that existing sofa grooving methods result in large groove sizes or increased installation difficulty.

[0004] To achieve the above objectives, this utility model provides a sofa back panel grooving device, comprising a frame; a flipping mechanism, disposed on the frame, for installing a sofa requiring grooving, which flips the sofa to expose the back panel for easier subsequent operation; a moving trolley, disposed on the top of the frame, moving laterally along the top of the frame; a crossbeam, disposed on the moving trolley, moving synchronously with the moving trolley and perpendicular to the moving trajectory of the moving trolley; a working trolley, disposed on the crossbeam, moving along the length of the crossbeam; and a rotating motor, disposed on the working trolley, with a grooving cutter mounted on its output shaft.

[0005] As a further improvement of this application, the top of the frame is provided with a first track groove, and the mobile trolley is disposed in the first track groove.

[0006] As a further improvement of this application, a pressure strip is also provided at the opening of the first track groove. The pressure strip is fixedly installed on the side wall of the opening of the first track groove by a stud. The cross-section of the moving trolley is convex, and the pressure strip presses against the step of the moving trolley.

[0007] As a further improvement of this application, a zeroing stop is provided in the first track groove, and a contact switch is provided on the side of the zeroing stop facing the mobile trolley. The contact switch is connected to the radio signal of the mobile trolley. When the mobile trolley touches the contact switch, the lateral position of the mobile trolley is zeroed.

[0008] As a further improvement of this application, each side of the crossbeam is provided with a second track groove, the cross section of the work vehicle is an inverted "U" shape, and a drive wheel is provided on the inner wall of the inverted "U" shape, the drive wheel being engaged in the second track groove.

[0009] As a further improvement of this application, the drive wheel is provided with a hub motor, which is a stepper motor.

[0010] As a further improvement of this application, a zeroing baffle is provided at one end of the second track groove, and a pressure switch is provided on the side of the zeroing baffle facing the drive wheel. The pressure switch is connected to the drive wheel via radio signal. When the drive wheel touches the pressure switch, the longitudinal position of the work vehicle is zeroed.

[0011] The beneficial effects of this utility model are as follows: After the sofa back panel is installed on the sofa, the sofa and the back panel are first installed on the flipping mechanism. By flipping the sofa, the back panel of the sofa is exposed. Then, a groove is directly made on the exposed back panel. In this way, the deflection angle and installation position of the groove are more accurate, which solves the problem of large groove size or increased installation difficulty caused by the existing groove making method of first making the back panel and then installing it.

[0019] like Figure 1 As shown, a sofa back panel grooving device includes a frame 1; a flipping mechanism 2, mounted on the frame 1, for mounting the sofa to be grooved, flipping the sofa to expose the back panel for subsequent grooving operations; a moving trolley 3, mounted on the top of the frame 1, moving laterally along the top of the frame 1; a crossbeam 4, mounted on the moving trolley 3, moving synchronously with the moving trolley 3 and perpendicular to its movement trajectory; a working carriage 5, mounted on the crossbeam 4, moving along the length of the crossbeam 4; and a rotating motor 6, mounted on the working carriage 5, with a grooving cutter 7 on its output shaft.

[0020] After the sofa back panel is installed on the sofa, the sofa and back panel are previously installed on the flipping mechanism 2. By flipping the sofa, the back panel is exposed, and then a groove is made directly on the exposed back panel. In this way, the deflection angle and installation position of the groove are more accurate, which solves the problem of large groove size or increased installation difficulty caused by the existing groove-making method of first cutting the back panel and then installing it.

[0021] By moving the trolley 3 laterally on the top of the frame 1 and the work trolley 5 along the length of the crossbeam 4, the positions of the rotating motor 6 and the grooving knife 7 are adjusted to groove different positions on the sofa back panel.

[0022] The flipping mechanism 2 includes a rotating disk mounted on the frame 1 and a claw mounted on the rotating disk. The rotating disk has the freedom to rotate around a horizontal line.

The pressure strip 12 presses against the step of the mobile trolley 3. The bottom of the mobile trolley 3 is provided with moving wheels, one or more of which are drive wheels, driving the mobile trolley 3 to move in the first track groove 11.

[0026] In order to reset and position the mobile trolley 3, a zeroing block 13 is provided in the first track groove 11. The zeroing block 13 has a contact switch on one side facing the mobile trolley 3. The contact switch is connected to the mobile trolley 3 via radio signal. When the mobile trolley 3 touches the contact switch, the lateral position of the mobile trolley 3 is reset to zero.

[0027] To limit the working vehicle 5, a second track groove 41 is provided on each of the two sides of the crossbeam 4. The cross-section of the working vehicle 5 is an inverted "U" shape, and a drive wheel 51 is provided on the inner wall of the inverted "U" shape. The drive wheel 51 is engaged in the second track groove 41. A hub motor is provided on the drive wheel 51, and the hub motor is a stepper motor. The drive wheel 51 drives the working vehicle 5 to move on the crossbeam 4.

[0028] In order to reset and position the work vehicle 5, a zeroing baffle 42 is provided at one end of the second track groove 41. A pressure switch is provided on the side of the zeroing baffle 42 facing the drive wheel 51. The pressure switch is wirelessly connected to the drive wheel 51. When the drive wheel 51 touches the pressure switch, the longitudinal position of the work vehicle 5 is zeroed.
