Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 4 In order to solve the problem that the existing carton flattening device generally flattens the cardboard or carton by moving the pressing plate up and down, the pressing plate is easily disturbed by external factors during the up and down movement, which may cause the movement trajectory to be unstable, thereby affecting the flattening effect, the following preferred technical solutions are provided:

[0022] A flattening device for carton production includes a body 1 and a conveying body 2 installed at the upper end of the body 1. A power body 3 is provided at the upper end of the body 1. The output end of the power body 3 is transmission-connected to a rolling roller 4. The rolling roller 4 is rotatably connected to the side wall of the conveying body 2. An adjusting roller assembly 5 is provided at the upper end of the conveying body 2. Two groups of the power body 3 and the rolling roller 4 are each provided, and are symmetrically distributed about the center of the conveying body 2. Multiple groups of the adjusting roller assemblies 5 are provided, and are distributed about both sides of the rolling roller 4.

[0023] The adjusting roller assembly 5 includes a middle connecting rod 51 and an adjusting roller body 52 rotatably connected to the outer wall of the middle connecting rod 51. The lower end of the middle connecting rod 51 is fixedly connected to a side connecting plate 53, and the side connecting plate 53 is fixedly connected to the side wall of the conveying body 2. The inner wall of the side connecting plate 53 is provided with a movable rod 54, and the movable rod 54 slides through the middle connecting rod 51 and the side connecting plate 53. The outer wall of the movable rod 54 is sleeved with a return spring 55, and the upper end of the return spring 55 is fixedly connected to the top of the side connecting plate 53. The upper and lower ends of the movable rod 54 are fixedly connected to a limit block 56, and a movable block A57 is fixedly connected to one side of the limit block 56 at the lower end of the movable rod 54. The outer wall of the side connecting plate 53 is provided with a first slide groove 58 and a second slide groove 59.

[0027] In summary: the cardboard to be flattened is placed between the rolling roller 4 and the adjusting roller assembly 5, the power body 3 is driven, the rolling roller 4 is driven to rotate by the power body 3, and the conveying body 2 is driven at the same time, the cardboard is conveyed by the conveying body 2, and the rolling roller 4 and the adjusting roller assembly 5 are used to flatten the cardboard. The rolling flattening method can ensure the uniform flattening of the cardboard. When the flattening work is being carried out, the adjusting roller body 52 will be pressed to drive the middle connecting rod 51 to press the side connecting plate 53, and the movable block A57 and the movable block B510 will be in The inner walls of the first slide groove 58 and the second slide groove 59 move to squeeze the reset spring 55. The reaction force of the reset spring 55 will drive the adjusting roller body 52 to press the cardboard, thereby improving the flattening efficiency. The adjusting roller body 52 can be manually pressed to control the distance. After the adjustment is completed, the fixing bolt 511 is rotated. The fixing bolt 511 moves on the inner wall of the movable block B510 until one end of the fixing bolt 511 presses against the side wall of the conveying body 2, thereby fixing the side connecting plate 53 and fixing the position of the adjusting roller body 52.
