At the same time, the pulley assembly drives the rotating rod to rotate, so that the fan rotates in the reverse direction, and the dust blown up on the corrugated cardboard is sucked into the collection box through the dust suction head and the pipeline, thereby preventing dust on the surface of the corrugated cardboard from affecting subsequent work.

[0023] Further, when the extrusion block no longer squeezes the air storage bag, the air storage bag self-supplements gas by using the air suction pipe, and at the same time, the one-way valve provided can prevent gas from generating turbulent flow. Description of the Drawings

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-6 , the present invention provides the following technical solution: An automatic corrugated board flipping device;

[0033] Embodiment 1: To solve the problem in the prior art that there is a lack of a function for clamping and fixing corrugated boards, resulting in the corrugated boards being easily thrown off due to too fast speed during the flipping process, causing the corrugated boards to be scattered and damaged. Therefore, the following solution is disclosed. Specifically refer to Figure 1 And Figure 2 And Figures 4-6 As shown in, it includes a bracket 1. Conveyor belt assemblies 2 are installed on both the left and right sides of the inner wall of the bracket 1, and a rotating cylinder 3 is arranged in the middle of the inner wall of the bracket 1. A first motor is fixed on the front of the bracket 1, and second motors are fixedly connected to both the left and right sides behind the bracket 1;

[0034] It further includes: the front end of the rotating cylinder 3 is fixedly connected to the output end of the first motor, the shaft ends of the conveyor belt assemblies 2 on the left and right sides are fixedly connected to the output ends of two second motors, the outer side of the rotating cylinder 3 is fixedly connected with movable plates 4 at equal angles, the periphery of the upper surface of the movable plates 4 is fixedly provided with limiting rods 11 at equal intervals, and a clamping plate 7 is sleeved outside the four limiting rods 11, and fitting blocks 6 are fixedly arranged on both the left and right sides of the upper surface of the clamping plate 7; a bidirectional threaded rod 9 is connected to the inside of the movable plate 4 by bearings, and moving plates 5 are sleeved outside both ends of the bidirectional threaded rod 9. The moving plates 5 are arranged in a "C" shape, and the moving plates 5 are in threaded connection with the bidirectional threaded rod 9, and the bottom of the moving plates 5 is in sliding connection with the inner wall of the movable plate 4. Guide rods 8 are arranged at the tops of the inner walls of the moving plates 5. The two sides of the fitting blocks 6 are inclined, and the inclined surfaces of the fitting blocks 6 are in contact with the bottoms of the guide rods 8. The clamping plate 7 is in sliding connection with the four limiting rods 11, and a support plate 13 is fixed at the tops of the four limiting rods 11; a reset spring 12 is connected between the lower surface of the support plate 13 and the upper surface of the clamping plate 7, and the relative ends of the four bidirectional threaded rods 9 and the outer side of the front end of the rotating cylinder 3 are driven and connected through a bevel gear set.

[0035] The two second motors can drive the conveyor belt assemblies 2 to work, so that the right conveyor belt assembly 2 transports the corrugated cardboard onto the movable plate 4. At this time, the first motor drives the rotating cylinder 3 to rotate, and drives the movable plate 4 to rotate, so that the corrugated cardboard on the movable plate 4 rotates in a circle, so that the corrugated cardboard falls onto the left conveyor belt assembly 2 after flipping and is transported to the designated position. Since there are multiple groups of movable plates 4, the movable plates 4 only need to rotate in a circle to flip and transport the corrugated cardboard, without having to turn back and flip, so that the corrugated cardboard can be continuous during the flipping process, improving the flipping efficiency. At the same time, when the first motor drives the rotating cylinder 3 to rotate, the rotating cylinder 3 drives the bidirectional threaded rod 9 to rotate by using the bevel gear set, so that the two moving plates 5 move relatively. At the same time, the guide rod 8 presses the fitting block 6, prompting the clamping plate 7 to move downward, and then the corrugated cardboard placed on the movable plate 4 can be clamped and fixed, so as to prevent the corrugated cardboard from falling during the flipping process. Then, when the first motor drives the rotating cylinder 3 to continue to rotate, the two moving plates 5 on the bidirectional threaded rod 9 continue to move relatively. Then, when the guide rod 8 slides from the right side of the fitting block 6 to the left side, the guide rod 8 no longer presses the fitting block 6, so that the clamping plate 7 resets under the elastic force of the reset spring 12 and no longer clamps and fixes the corrugated cardboard.

[0036] Embodiment 2: Different from Embodiment 1, in this embodiment, the nozzle can blow air to clean the surface of the corrugated cardboard, and at the same time, the suction head sucks the blown dust into the collection box 15 to achieve the dust removal work of the corrugated cardboard. For specific reference Figure 2 and Figure 3As shown in the figure, a collection box 15 is bolted to the left side behind the bracket 1. A rotating rod 16 is connected to the inside of the collection box 15 by means of a bearing. A fan is installed at the rear end of the rotating rod 16. A pipe 17 is fixedly connected to the front of the collection box 15, and a dust suction head is installed at the front end of the pipe 17. The outer side of the front end of the rotating rod 16 is drivingly connected to the shaft end of the left conveyor belt assembly 2 through a pulley assembly. A pressing block 19 is fixedly sleeved on the outer side of the shaft end of the left conveyor belt assembly 2. A storage air bag 10 is arranged on the left side of the front of the bracket 1. The right end of the storage air bag 10 is fixedly connected to an air delivery pipe 18, and a spray head is installed at one end of the air delivery pipe 18 away from the storage air bag 10. The pressing block 19 corresponds to the position of the storage air bag 10. One ends of the air delivery pipe 18 and the pipe 17 both extend into the inner wall of the bracket 1;

[0037] When the left conveyor belt assembly 2 transports the corrugated cardboard, it can drive the pressing block 19 to rotate and reciprocally press the storage air bag 10, so that the gas in the storage air bag 10 enters the air delivery pipe 18, and the gas is blown onto the corrugated cardboard through the spray head for blowing and cleaning. At the same time, the pulley assembly is used to drive the rotating rod 16 to rotate, so that the fan rotates in the reverse direction, and the dust blown up on the corrugated cardboard is sucked into the collection box 15 through the dust suction head and the pipe 17 for collection, realizing the dust removal work of the corrugated cardboard, thereby avoiding the influence of dust on the surface of the corrugated cardboard on the subsequent work.

[0038] Embodiment 3: Different from Embodiment 2, in this embodiment, the one-way valve provided can prevent the gas from generating turbulent flow, specifically refer to Figure 2 and Figure 3 As shown in the figure, an air suction pipe 14 is arranged at the bottom of the storage air bag 10, and one-way valves are installed inside both the air suction pipe 14 and the air delivery pipe 18;

[0039] When the pressing block 19 no longer presses the storage air bag 10, the storage air bag 10 can automatically return to its original state, and the gas is automatically replenished by using the air suction pipe 14. At the same time, the one-way valve provided enables the outside air to only enter the storage air bag 10 from the air suction pipe 14, while the gas in the storage air bag 10 enters the spray head from the air delivery pipe 18, thereby avoiding the generation of turbulent flow of the gas.

[0040] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
