[0002] The manufacture of paper products refers to the production activities of using paper and cardboard as raw materials to process and produce various paper products. These paper products have the advantages of high cost performance, good elasticity and toughness, etc. Double-sided processing of paper products refers to the process of double-sided printing or processing of paper products, which involves printing or processing the front and back sides of paper products. This processing method can improve the use value and aesthetics of paper products, and at the same time can also save costs and improve production efficiency. During the processing, a turnover clamping device is needed to clamp the paper products and then turn them over; in the prior art, when turning over the products, it is necessary to use a driving component to drive the clamping plates to move relatively, clamp the paper products through the cooperation of the two clamping plates, and then use another driving component to drive the two clamping plates to rotate to turn over the clamped paper products. The clamping plates need to move and rotate in two motion modes, resulting in most clamping and turning devices having multiple driving components, with a large input cost, and it is more inconvenient to control the clamping force, and it is easy to drop the paper products during the turning process. Content of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A turnover clamping device for double-sided processing of paper products, including a housing and an adjusting mechanism;

[0005] Housing: A rotating pipe is rotatably connected to the upper end thereof, a turnover plate is arranged at the front end of the rotating pipe, and clamping plates are slidably connected to both the upper and lower ends of the turnover plate;

The clamping force on the paper product when starting to flip can be controlled to avoid the situation that the paper product drops due to too small clamping force during the flipping process, making the flipping process of the paper product more stable and improving the efficiency of double-sided processing of the paper product.

[0007] Further, the adjusting mechanism further includes a gear, a rotating ring and a hexagonal column. The gear is rotatably connected to the lower end of the housing through the rotating ring.

The external toothed ring is meshed with the gear, which is convenient for rotating the external toothed ring.

[0008] Further, the adjusting mechanism further includes a clamping plate and a clamping groove. The clamping groove is arranged on the rear side surface of the housing, and the clamping plate is arranged at the rear end of the hexagonal column.

[0012] Further, a motor is arranged on the rear side surface of the housing. The output shaft of the motor is fixedly connected to the rotating column. The input end of the motor is electrically connected to the input end of the single-chip microcomputer to provide power for the rotation of the rotating column.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: The flipping and clamping device for double-sided processing of paper products has the following advantages:

[0014] Under the torsional force of the torsion spring, the driving component first drives the clamping plates to approach each other to clamp the paper product, and then drives the clamping component to rotate to flip the clamped paper product. Before use, the torsion spring is pre-twisted by rotating the external tooth ring, so that the force required for the torsion spring to twist at the beginning of flipping is greater.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: A flipping and clamping device for double-sided processing of paper products, including a housing 1 and an adjusting mechanism 5;

[0021] Shell 1: A rotating tube 2 is rotatably connected to its upper end. A turning plate 3 is provided at the front end of the rotating tube 2. Clamping plates 4 are slidably connected to both the upper and lower ends of the turning plate 3. The paper products are clamped by the relative movement of the two clamping plates 4. The turning plate 3 is driven by the rotating tube 2 to rotate, and the paper products in the clamped state are turned over. Screws 6 are rotatably connected to both the upper and lower ends of the turning plate 3. The screws 6 are threadedly connected to the clamping plates 4. Small bevel gears 7 are provided at the ends of the screws 6 close to the rotating tube 2. A rotating column 9 is rotatably connected to the inside of the rotating tube 2. A large bevel gear 8 is provided at the front end of the rotating column 9. The small bevel gears 7 are all meshed with the large bevel gear 8. The rotating column 9 drives the large bevel gear 8 to rotate. Through the meshing connection between the large bevel gear 8 and the small bevel gears 7, the screws 6 are driven to rotate. Through the threaded connection between the screws 6 and the clamping plates 4, the two clamping plates 4 are driven to approach each other to clamp the paper products. A single-chip microcomputer 11 is provided on the surface of the shell 1 to control the start and stop of the whole device. The input end of the single-chip microcomputer 11 is electrically connected to an external power supply. A motor 10 is provided on the rear side of the shell 1. The output shaft of the motor 10 is fixedly connected to the rotating column 9. The input end of the motor 10 is electrically connected to the input end of the single-chip microcomputer 11 to provide power for the rotation of the rotating column 9;

[0022] Adjusting mechanism 5: It includes an external tooth ring 51 and a torsion spring 52. The external tooth ring 51 is rotatably connected to the outer arc surface of the rotating tube 2, and the angle of the external tooth ring 51 can be limited and adjusted. The torsion spring 52 is movably sleeved on the outer arc surface of the rotating tube 2. The rear end of the torsion spring 52 is fixedly connected to the external tooth ring 51, and the front end of the torsion spring 52 is fixedly connected to the connecting ring at the front end of the rotating tube 2. When the rotating column 9 rotates, under the action of the torsion force of the torsion spring 52, the rotation of the rotating tube 2 and the turning plate 3 is restricted. At this time, the rotation of the rotating column 9 drives the clamping plate 4 to move. After the clamping plate 4 clamps the paper product, the rotation of the rotating column 9 will drive the turning plate 3 and the rotating tube 2 to rotate, causing the torsion spring 52 to twist and flipping the clamped paper product. Before use, by rotating the external tooth ring 51, the torsion spring 52 can be pre-twisted, so that the force required for the torsion spring 52 to twist at the beginning of flipping is greater, and the clamping plate 4 clamps the paper product more firmly. The adjusting mechanism 5 further includes a gear 53, a rotating ring 54, and a hexagonal column 55. The gear 53 is rotatably connected to the lower end of the housing 1 through the rotating ring 54. A hexagonal column 55 is horizontally slidably connected in the hexagonal hole in the middle of the gear 53. The external tooth ring 51 is meshed with the gear 53. The hexagonal column 55 and the gear 53 can only rotate synchronously. By rotating the hexagonal column 55, the gear 53 is driven to rotate. Through the meshing connection between the gear 53 and the external tooth ring 51, the external tooth ring 51 is driven to rotate. The adjusting mechanism 5 further includes a clamping plate 57 and a clamping groove 58. The clamping groove 58 is arranged on the rear side surface of the housing 1. The clamping plate 57 is arranged at the rear end of the hexagonal column 55. The clamping plate 57 is fitted and installed with the limiting clamping grooves distributed annularly along the outer edge of the clamping groove 58. By the clamping connection between the clamping plate 57 and the limiting clamping grooves on the outer edge of the clamping groove 58, the rotation of the hexagonal column 55 is restricted. The adjusting mechanism 5 further includes a spring 56. The spring 56 is arranged between the limiting disc at the front end of the hexagonal column 55 and the gear 53. The spring 56 is movably sleeved on the outer arc surface of the hexagonal column 55. Under the elastic force of the spring 56, the clamping plate 57 is kept in a state of being clamped with the limiting clamping grooves on the outer edge of the clamping groove 58.

[0023] The working principle of a flipping and clamping device for double-sided processing of paper products provided by the present utility model is as follows: During the double-sided processing of paper products, the motor 10 is started by the single-chip microcomputer 11. The output shaft of the motor 10 drives the rotating column 9 and the large bevel gear 8 to rotate. At this time, under the torsion force of the torsion spring 52, the rotation of the rotating tube 2 and the flipping plate 3 is restricted. Through the meshing connection of the large bevel gear 8 and the small bevel gear 7, the screw rod 6 is driven to rotate. Through the threaded connection of the screw rod 6 and the clamping plate 4, the two clamping plates 4 are driven to approach each other to clamp the paper product. The paper product blocks the continuous movement of the two clamping plates 4, thereby restricting the rotation of the screw rod 6. Therefore, at this time, the rotation of the rotating column 9 will drive the flipping plate 3 and the rotating tube 2 to rotate, causing the torsion spring 52 to twist, and flipping the clamped paper product. Before use, the clamping plate 57 can be pulled backward and rotated to change the clamping position of the clamping plate 57 with the outer edge limit card slot of the card slot 58. Through the horizontal sliding connection of the hexagonal column 55 and the gear 53, the gear 53 is driven to rotate. Through the meshing connection of the gear 53 and the external tooth ring 51, the external tooth ring 51 is driven to rotate, and the torsion spring 52 is pre-twisted, so that the force required for the torsion spring 52 to twist at the beginning of flipping is greater, and the clamping of the paper product by the clamping plate 4 during the flipping process is more firm.

[0024] It should be noted that, in the above embodiments, the single-chip microcomputer 11 disclosed can be an AT89C4051 model single-chip microcomputer, and the motor 10 can be freely configured according to the actual application scenario. It is recommended to select a 42BYHJ01 model stepping reduction motor. The single-chip microcomputer 11 controls the motor 10 to work using the commonly used methods in the prior art.

[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
