[0039] The present application relates to a door panel processing center, and more specifically to a door panel conveying mechanism in the door panel processing center. The door panel conveying mechanism is used to convey the door panel 50 along the length direction of the door panel 50, and the door panel conveying mechanism is suitable for conveying door panels 50 of different widths. At the same time, the door panel 50 is conveyed by the door panel conveying mechanism in a lying posture. For the convenience of description, in the following embodiments, the length direction of the door panel 50 conveyed by the door panel conveying mechanism is defined as the front-to-back direction, and the width direction of the door panel 50 conveyed by the door panel conveying mechanism is defined as the left-to-right direction.

[0040] like Figure 1 and Figure 2As shown, the door panel conveying mechanism involved in the present application includes a fixedly arranged machining center bed, a left conveying unit 11, a right conveying unit 12, an adjusting driving source and a plurality of groups of pressure wheel assemblies 20. Among them, the left conveying unit 11 and the right conveying unit 12 are relatively distributed left and right along the width direction of the door panel 50, and both the left conveying unit 11 and the right conveying unit 12 are installed on the machining center bed. The conveying directions of the left conveying unit 11 and the right conveying unit 12 are consistent with the length direction of the door panel 50, and both convey the door panel 50 along the front-to-back direction. In particular, the left conveying unit 11 is installed on the machining center bed so as to be movable left and right along the width direction of the door panel 50, and the adjusting driving source is installed on the machining center bed. The adjusting driving source is transmission-connected with the left conveying unit 11 to drive the left conveying unit 11 to move left and right. The plurality of groups of pressure wheel assemblies 20 are all installed on the machining center bed; among the plurality of groups of pressure wheel assemblies 20, at least some groups of pressure wheel assemblies 20 are distributed side by side front and back along the length direction of the door panel 50 directly above the right conveying unit 12; as shown in FIG. Figure 3 As shown, each group of pressure wheel assemblies 20 includes a lifting drive source 21 and a lifting pressure wheel 22. The lifting drive source 21 is transmission-connected to the lifting pressure wheel 22 to drive the lifting pressure wheel 22 to move up and down. When the lifting drive source 21 drives the lifting pressure wheel 22 to move downward, the lifting pressure wheel 22 and the right conveying unit 12 are respectively clamped on the upper and lower sides of the door panel 50.

[0041] In the door panel conveying mechanism involved in the present application, the conveying directions of the left conveying unit 11 and the right conveying unit 12 are consistent, and the spacing between the left conveying unit 11 and the right conveying unit 12 matches the width of the door panel 50. The door panel 50 is conveyed in the front-to-back direction by the left conveying unit 11 and the right conveying unit 12, so that the door panel processing center can process the lock hole vertical surface, lock hole horizontal surface, top groove, bottom groove and hinge groove on the door panel 50. When the width of the next door panel 50 to be processed changes, the driving source is adjusted to drive the left or right movement of the left conveying unit 11, and the position of the left conveying unit 11 in the width direction of the door panel 50 is adjusted, thereby adjusting the spacing between the left conveying unit 11 and the right conveying unit 12 in the width direction of the door panel 50, so that the spacing between the left conveying unit 11 and the right conveying unit 12 matches the width of the next door panel 50 to be processed. Therefore, the present application adjusts the left and right positions of the left conveying unit 11 in the width direction of the door panel 50 by adjusting the driving source, so that the door panel conveying mechanism is suitable for conveying door panels 50 of different widths. In particular, the present application configures multiple groups of pressure wheel assemblies 20 on the upper side of the right conveying unit 12, so that the multiple groups of pressure wheel assemblies 20 and the right conveying unit 12 can clamp the right side of the door panel 50 to convey the door panel 50. In this way, the action of adjusting the driving source to drive the left conveying unit 11 to move left and right, and the action of lifting and lowering the pressure wheel 22 and the right conveying unit 12 to clamp and convey the door panel 50 can be carried out simultaneously, that is, the left and right positions of the left conveying unit 11 are adjusted simultaneously during the process of conveying the door panel 50. Compared with the method of adjusting the left and right positions of the left conveying unit 11 after the door is conveyed in the prior art, the present application effectively shortens the adjustment time to match the width of the door panel 50, which is conducive to speeding up the processing of the door panel 50 and improving the processing efficiency of the door panel 50.

The lower end of the cylinder piston rod of the lifting drive source 21 is connected to the pressure roller lifting seat 23, and the lifting pressure roller 22 is rotatably installed on the pressure roller lifting seat 23. In this way, in the process of conveying the door panel 50 on the right side of the door panel 50 while clamping the multiple groups of pressure roller assemblies 20 and the right conveying unit 12, the lifting pressure roller 22 is in rolling contact with the door panel 50, thereby improving the stability of the door panel conveying.

After the processing is completed, the left conveying unit 11 and the right conveying unit 12 both rise until they are higher than the left adsorption platform 31 and the right adsorption platform 32, and the door panel 50 is transferred to the left conveying unit 11 and the right conveying unit 12, and the left conveying unit 11 and the right conveying unit 12 can convey the door panel 50.
