Technical Field

[0001] The utility model belongs to the technical field of cardboard processing, and in particular relates to a retractable and unfoldable cardboard turning machine. Background Art

[0002] After the cardboard is produced from the cardboard production line, it is often necessary to flip it over for the convenience of subsequent processing and printing. However, manual flipping is labor-intensive and inefficient. For this reason, a cardboard flipping machine is developed that can transport the cardboard to the cardboard and flip it over.

[0003] In the Chinese patent with the announcement number CN209038994U, a flipping machine is mentioned. It has low cost and simple structure. It uses a motor to drive the transmission ring to rotate, so that the bracket installed on it rotates, thereby achieving the purpose of flipping the product placed between the lifting fixtures. The operation is simple and easy to promote. However, when flipping the plate, the above-mentioned flipping machine cannot automatically push out the internal objects, and it cannot effectively maintain stability during the flipping process, and there are certain limitations on its use. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 4 As shown, a retractable cardboard flipping machine includes:

[0027] A support base 1, support plates 2 are fixedly mounted on both sides of the top of the support base 1, and a support mechanism is provided on the top of the support base 1;

[0028] The turning mechanism is arranged between the two support plates 2, and the turning mechanism includes a turning roller 3, and a placing frame 4 is fixedly installed on both sides of the turning roller 3;

[0029] The push mechanism includes an annular groove 5 provided on one side of the support plate 2 and two sliding grooves 6 extending through one side of the placement frame 4. Push rods 7 are slidably installed inside the two placement frames 4. The outer surfaces of the two push rods 7 are slidably connected to the inner surfaces of the sliding groove 6 and the annular groove 5.

[0030] The limiting mechanism is arranged on the side where the two placement frames 4 are away from each other.

[0031] Depend on Figure 1 , Figure 2 and Figure 4 It can be seen that the support mechanism includes support platforms 8 fixedly installed around the top of the support base 1, and support wheels 9 are rotatably installed on the opposite sides of the support platforms 8 on both sides, and the outer surface of the support wheel 9 is transmission-connected to the outer surface of the turning roller 3.

[0032] As can be seen from the above, when in use, two conveyor belts are respectively arranged at the openings of the two placement frames 4, a loading conveyor belt is arranged at the placement frame 4 where the push rod 7 is located at the right end of the sliding groove 6, and a unloading conveyor belt is arranged at the opening of the other placement frame 4, and one or more support wheels 9 are connected to the external driving device so that the support wheel 9 can drive the flip roller 3 to rotate, and the loading conveyor belt is started, so that the loading conveyor belt transports the cardboard to the inside of the placement frame 4. At this time, the limit mechanism is opened, and the cardboard enters the inside of the placement frame 4. The driving mechanism drives the support wheel 9 to make the flip roller 3 rotate clockwise. During the movement, the limiting mechanism is closed, and the cardboard is restricted inside the placement frame 4. When the flip roller 3 rotates 180 degrees, the push rod 7 slides along the annular groove 5, and the limiting mechanism gradually opens. After rotating to 180 degrees, the limiting mechanism is fully opened, and the push rod 7 moves to the other end of the sliding groove 6 to push the internal cardboard out of the placement frame 4 so that it contacts the unloading conveyor belt. The unloading conveyor belt will pull the flipped cardboard out of the placement frame 4 and transport it to the outside. At this time, another placement frame 4 rotates to the position of the original placement frame 4, and the above steps can be repeated to flip the cardboard.

[0033] Embodiment 2:

[0034] refer to Figure 1 and Figure 3 As shown, the limiting mechanism includes a clamping plate 10 slidably installed on the top and bottom of the placement frame 4, and the opposite sides of the two clamping plates 10 extend to the inside of the placement frame 4. Limiting columns 11 are fixedly installed on both sides of the top and bottom of the placement frame 4. The outer surface of the limiting column 11 is slidably connected to the inner surface of the clamping plate 10. A spring 12 is fixedly installed between the limiting column 11 and the clamping plate 10. The limiting mechanism also includes a sliding ring 13 fixedly installed on the opposite side of the two support plates 2, and protrusions are provided on both sides of the sliding ring 13. A rotating shaft 14 is fixedly installed on both sides of the clamping plate 10, and the outer surface of the rotating shaft 14 is slidably connected to the outer surface of the sliding ring 13.

[0035] As can be seen from the above, during the process of loading and unloading the cardboard, the rotating shaft 14 is pressed against the protrusion on the sliding ring 13, so that the two clamping plates 10 are separated and the opening of the placement frame 4 is opened. When the flip roller 3 rotates, the internal placement frame 4 and the clamping plates 10 thereon are driven to rotate at the same time. When the rotating shaft 14 is away from the protrusion, the spring 12 will push the clamping plates 10 toward the inside of the placement frame 4, so that the two clamping plates 10 are pressed against each other, and the opening of the placement frame 4 is closed, thereby preventing the cardboard from falling and the angle from shifting.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
