Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard flipping machine technology, specifically a corrugated cardboard flipping machine. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one corrugated core paper layer and one cardboard layer. Corrugated cardboard needs to be flipped during processing, so a flipping machine is required to flip the corrugated cardboard.

[0003] To improve the applicability of corrugated cardboard flipping machines, existing technologies have made numerous improvements. For example, patent publication number CN216548707U discloses a corrugated cardboard flipping machine, including a frame, a conveying module mounted on the frame, and a flipping module mounted on the frame and adapted to the conveying module. The conveying module includes a conveyor belt, a storage trough, a storage platform, and a pick-and-place port. The flipping module includes vertical plates mounted on the frame and located at the left and right ends of the conveyor belt, a linear slide mounted vertically on the inner side wall of the lower end of the vertical plates, a first telescopic push rod mounted horizontally on a slide block of the linear slide and connected to a motor with the output shaft of the first telescopic push rod, and an electric gripper connected to the output shaft of the motor and adapted to the pick-and-place port. This corrugated cardboard flipping machine not only quickly conveys corrugated cardboard to be flipped and after flipping, but also is suitable for flipping various sizes and specifications of corrugated cardboard, exhibiting strong applicability.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes the use of electric grippers to hold corrugated cardboard and a motor to flip the cardboard. However, in reality, some corrugated cardboard pieces are quite large, requiring a long upward travel distance for the grippers after being held. Furthermore, each flip requires both upward and downward movement, thus reducing the efficiency of flipping the cardboard. Therefore, there is an urgent need in the field to improve the corrugated cardboard flipping machine to address the shortcomings of the existing technology. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a corrugated cardboard flipping machine to improve the efficiency of flipping corrugated cardboard.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard flipping machine, comprising two symmetrical mounting frames, with a plurality of transmission rollers rotatably connected between the upper parts of the two mounting frames. A first drive unit for driving the plurality of transmission rollers to rotate simultaneously is provided on one side of each mounting frame.

[0013] Preferably, the clamping frame is hollow.

[0014] To address the shortcomings of existing technologies, this utility model provides a corrugated cardboard flipping machine, which overcomes the deficiencies of existing technologies. The beneficial effects of this utility model are as follows:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-8 A corrugated cardboard flipping machine includes two symmetrical mounting frames 1. Several transmission rollers 2 are rotatably connected between the upper parts of the two mounting frames 1. A first drive unit 3 is provided on one side of the mounting frame 1 for driving the several transmission rollers 2 to rotate simultaneously. A support seat 4 is provided below the mounting frame 1. A movable plate 5 is slidably connected to the upper surface of the support seat 4. A second drive unit 6 is provided on one side of the support seat 4 for driving the movable plate 5 to move. Several rotating seats 7 located between the transmission rollers 2 are provided on the movable plate 5. Two symmetrical clamping frames 8 adapted to the transmission rollers 2 are provided on one side of the rotating seats 7. A third drive unit 9 is provided on the movable plate 5 for driving the several rotating seats 7 to rotate simultaneously. A fourth drive unit 10 is provided on the rotating seats 7 for driving the two clamping frames 8 to move towards or away from each other.

[0029] Specifically, two mounting brackets 1 are installed between two existing conveyor belts. The corrugated cardboard on the conveyor belts has a certain spacing to allow sufficient time for the corrugated cardboard to be properly positioned. The conveyor belts transport larger volumes of corrugated cardboard to the drive rollers 2. The first drive unit 3 drives several drive rollers 2 to rotate and transport the corrugated cardboard. When the corrugated cardboard is positioned between several clamping brackets 8, the fourth drive unit 10 is activated. The fourth drive unit 10 drives two clamping brackets 8 to move towards each other to clamp the corrugated cardboard. Simultaneously, the second drive unit 6 and the third drive unit 9 are activated. The second drive unit 6 drives the moving plate 5 onto the support seat 4. The third drive unit 9 drives the rotating seat 7 to rotate. Several rotating seats 7 rotate while moving between two adjacent transmission rollers 2. When the moving plate 5 moves to the other side of the bearing seat 4, the rotating seat 7 rotates at a flat angle to flip the corrugated cardboard. The two clamping frames 8 are opened again by the fourth drive unit 10, and the first drive unit 3 is started to continue conveying the corrugated cardboard. In this embodiment, the moving plate 5 only needs to move once. The corrugated cardboard is flipped while the moving plate 5 is moving, which reduces the time used to flip the corrugated cardboard and thus improves the efficiency of flipping the corrugated cardboard.

[0032] As a technical optimization of this utility model, the second drive unit 6 includes a second drive motor 15 fixedly installed on one side of the support seat 4, a first sliding block 16 fixedly installed on the lower surface of the moving plate 5, a first sliding groove 17 adapted to the first sliding block 16 opened on the upper surface of the support seat 4, an adjusting screw 18 extending to the outside is rotatably connected in the first sliding groove 17, one end of the adjusting screw 18 is fixedly connected to the output end of the second drive motor 15, the adjusting screw 18 passes through the first sliding block 16 and is threadedly connected to the first sliding block 16, there are two first sliding blocks 16, first sliding grooves 17 and adjusting screws 18, a second transmission wheel 19 is fixedly installed on the side of the two adjusting screws 18 located on the outside, and a second transmission belt 20 for transmission is sleeved between the sides of the two second transmission wheels 19.

[0033] Specifically, the second drive motor 15 is started, and the output end of the second drive motor 15 drives the first second transmission wheel 19 to rotate. The second transmission wheel 19 drives the other second transmission wheel 19 to rotate through the second transmission belt 20. The two second transmission wheels 19 drive the adjusting screw 18 to rotate. When the adjusting screw 18 rotates, it drives the first sliding block 16 to slide in the first sliding groove 17. The two first sliding blocks 16 drive the moving plate 5 to move.

[0034] As a technical optimization of this utility model, the third drive unit 9 includes a third drive motor 21 fixedly installed on the movable plate 5. A mounting plate 22 for mounting the third drive motor 21 is fixedly connected to the upper surface of the movable plate 5.
