DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0035] Example 1:

[0036] The present application discloses a paper box corrugated paper sheet turning conveying device. Referring to Figure 1The steering and conveying device includes a roller conveyor belt 1, a support frame 2, a first drive component 3, and a second drive component 4. The roller conveyor belt 1 is used to transport corrugated paper sheets. The support frame 2 is embedded in the roller conveyor belt 1. The first drive component 3 is used to drive the support frame 2 to move up and down, and the second drive component 4 is used to drive the support frame 2 to rotate. In use, the corrugated paper sheets are first transported by the roller conveyor belt 1. When the corrugated paper sheets move above the support frame 2, the first drive component 3 drives the support frame 2 upward, and then the second drive component 4 drives the support frame 2 to rotate, thereby realizing the reversal of the paperboard's orientation. Then, the support frame 2 is moved downward, so that the support frame 2 returns to the roller conveyor belt 1, and the corrugated paper sheets fall back onto the roller conveyor belt 1 and continue to be transported forward by the roller conveyor belt 1.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the support frame 2 includes a center plate 21 and a first rod 22 and a second rod 23 disposed on the side wall of the center plate 21. The center plate 21 is preferably rectangular. The first rod 22 is disposed along the conveying direction of the roller conveyor belt 1 and is disposed on two parallel side walls of the center plate 21. The second rod 23 is disposed along the direction perpendicular to the roller conveyor belt 1 and is also disposed on two parallel side walls of the center plate 21. Furthermore, two of the first rod 22 and the second rod 23 are disposed parallel to each other on the corresponding side walls of the center plate 21, thus making the entire support frame 2 form a "well" shape. This structure improves the support effect of the support plate on the corrugated paper and prevents the corrugated paper from falling off during turning.

[0038] Reference Figure 1 and Figure 2 The roller conveyor belt 1 has several conveyor rollers 11 spaced apart along the conveying direction for conveying corrugated cardboard, and is equipped with a drive device for driving the rotation of the conveyor rollers 11. The rotation drive method of the conveyor rollers 11 in the roller conveyor belt 1 is existing technology and will not be described in detail here. When the support frame 2 is embedded in the roller conveyor belt 1, all the second rods 23 are located between two adjacent conveyor rollers 11. The roller conveyor belt 1 has a relief groove 12 for accommodating the first rod 22, and conveyor rollers 11 are arranged on both sides of the first rod 22 and between two adjacent first rods 22. Specifically, the roller conveyor belt 1 has baffles 13 on both sides of the first rod 22 for mounting the conveyor rollers 11, and both ends of the conveyor rollers 11 supported by the two first rods 22 are rotatably connected to the baffles 13. This arrangement ensures sufficient friction for the corrugated cardboard sheet conveyed above the support frame 2 to move the corrugated cardboard sheet.

[0039] Reference Figure 1 and Figure 2In the embodiment of the present application, the first rod 22 and the second rod 23 are preferably made of metal material to have high strength and rigidity, so as to ensure that they are not easily deformed when bearing a large load. In order to ensure the stability of the first rod 22 and the second rod 23, the first rod 22 and the second rod 23 are provided with reinforcing ribs 25 at the connection positions with the center plate 21. The reinforcing ribs 25 are in triangular shape and mainly used for enhancing the connection strength of the first rod 22 and the second rod 23 with the center plate 21, so as to prevent the connection from being broken when a large impact force is applied. The reinforcing ribs 25 can be fixed by welding or bolt connection, so as to ensure firm and reliable connection. Further, the center plate 21, the first rod 22 and the second rod 23 are all provided with anti-skid pads 24 on the upper surfaces, and the surfaces of the anti-skid pads 24 can be provided with anti-skid lines, so as to increase the friction between the paperboard and the support frame 2 and prevent the paperboard from sliding or deviating during transportation. The anti-skid pads 24 can be made of rubber material or silica gel material, both of which have good wear resistance and weather resistance and can maintain excellent anti-skid performance for a long time.

The air cylinders 31 are fixed on the positioning plates 6, and the extension shafts of the air cylinders 31 slide through the positioning plates 6 in the vertical direction. The end portions of the extension shafts of the air cylinders 31 are connected with the movable plates 5, so that the air cylinders 31 can drive the movable plates 5 and the support frames 2 to move up and down. Further, in order to improve the stability of the upward and downward movement of the movable plates 5, two air cylinders 31 can be correspondingly arranged. Meanwhile, the lower surfaces of the movable plates 5 can be fixed with guide rods 51 by welding or the like. The guide rods 51 can be arranged at the four corners of the movable plates 5, respectively. The positioning plates 6 are correspondingly provided with guide grooves 61 for the guide rods 51 to slide through. The guide rods 51 slide through the guide grooves 61 one by one, and the cooperation of the guide rods 51 and the guide grooves 61 can further improve the stability of the upward and downward movement of the movable plates 5.

[0041] With reference to Figure 2 In the embodiment of the present application, the second driving member 4 can be a motor or a rotary air cylinder 31, and in the embodiment, the second driving member 4 is preferably a servo motor 41. The servo motor 41 is fixed on the movable plate 5, and the output shaft of the servo motor 41 is connected with the center plate 21, so that the servo motor 41 can drive the support frame 2 to rotate when started.

[0042] The implementation principle of the carton corrugated paper sheet turning conveying device is as follows: the corrugated paper sheet is placed on the roller conveying belt 1 for transportation; when the corrugated paper sheet is moved to above the support frame 2 under the driving of the conveying roller 11, the air cylinder 31 is started to drive the movable plate 5 and the support frame 2 to move upward, at this time, the corrugated paper sheet is synchronously moved upward; then, the servo motor 41 is started to drive the support frame 2 to rotate by 180 degrees to drive the corrugated paper sheet to turn; then, the air cylinder 31 is started again to drive the movable plate 5 and the support frame 2 to move downward and embed into the roller conveying belt 1; at this time, the conveying roller 11 continues to rotate to drive the turned corrugated paper sheet to move forward.
