Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] Please see Figures 1 to 5 A clamping and flipping device for a trademark paper 6 according to an embodiment of the present invention includes a clamping mechanism 1 and a flipping mechanism 2. The clamping mechanism 1 is used to clamp the trademark paper 6 when the inkjet surface of the trademark paper 6 is transported to a preset position with the inkjet surface facing a first preset direction. The flipping mechanism 2 is connected to the clamping mechanism 1 and is used to drive the clamping mechanism 1 to rotate by a preset angle, so that the clamping mechanism 1 drives the trademark paper 6 to rotate until the inkjet surface of the trademark paper 6 faces a second preset direction opposite to the first preset direction.

[0020] Here, the printed surface of the trademark paper 6 is oriented towards the first preset direction to facilitate scanning by the scanning device. When the clamping mechanism 1 transports the trademark paper 6 to the preset position, the scanning device can scan the trademark paper 6. After the trademark paper 6 is scanned, the flipping mechanism 2 drives the clamping mechanism 1 to rotate by a preset angle. The clamping mechanism 1 then rotates the trademark paper 6 so that the printed surface of the trademark paper 6 faces the second preset direction opposite to the first preset direction, thus achieving automatic flipping of the scanned trademark paper 6. Alternatively, the clamping mechanism 1 can transport the trademark paper 6 to a position between the preset positions. At this time, the scanning device can scan the trademark paper 6. After the trademark paper 6 is scanned, the clamping mechanism 1 transports the trademark paper 6 to the preset position. Then, the flipping mechanism 2 drives the clamping mechanism 1 to rotate by a preset angle. The clamping mechanism 1 then rotates the trademark paper 6 so that the printed surface of the trademark paper 6 faces the second preset direction opposite to the first preset direction, thus achieving automatic flipping of the scanned trademark paper 6. The scanned trademark paper 6 is flipped over to change the orientation of the printed surface, thus facilitating the subsequent stacking of the trademark paper 6.

[0021] Specifically, the first preset direction can be vertically upward, and the second preset direction can be vertically downward. The preset angle can be 180 degrees.

[0022] The clamping mechanism 1 may include a support member 13, a conveying member 11, and a clamping adjustment member 12. The conveying member 11 and the clamping adjustment member 12 are both connected to the support member 13. The conveying member 11 is used to convey the label paper 6 with the inkjet surface facing the vertical upward direction to a preset position and stop. The clamping adjustment member 12 is used to abut against the inkjet surface of the label paper 6 and cooperate with the conveying member 11 to clamp the label paper 6. The flipping mechanism 2 is connected to the support member 13 and is used to drive the support member 13 to rotate by a preset angle, so that the clamping mechanism 1 drives the label paper 6 to rotate until the inkjet surface of the label paper 6 faces the vertical downward direction.

[0023] Specifically, the label paper 6 is placed on the conveyor 11, with the coding surface of the label paper 6 facing vertically upwards. The coding surface of the label paper 6 is the top surface of the label paper 6, and the bottom surface of the label paper 6 abuts against the conveyor 11. The conveyor 11 conveys the label paper 6 to a preset position and then stops. At this time, the clamping adjustment member 12 moves to abut against the coding surface of the label paper 6, that is, the clamping adjustment member 12 abuts against the top surface of the label paper 6. At this time, the clamping adjustment member 12 is located above the conveyor 11. At this time, the flipping mechanism 2 drives the support member 13 to rotate by a preset angle, which can be 180 degrees. This can drive the conveyor 11 and the clamping adjustment member 12 to rotate by the corresponding angles. The conveyor 11 is located above the clamping adjustment member 12. The conveyor 11 and the clamping adjustment member 12 drive the label paper 6 to rotate, with the coding surface of the label paper 6 facing vertically downwards. At this time, the coding surface of the label paper 6 is the bottom surface of the label paper 6.

[0024] As a trademark paper 6 clamping and flipping device in this embodiment, it may also include a detection element and a controller for controlling the clamping mechanism 1 and the flipping mechanism 2 respectively; the detection element is disposed on the support 13 along the conveying direction of the conveyor 11 and is used to detect the trademark paper 6; the controller is used to control the flipping mechanism 2 to drive the clamping mechanism 1 to rotate by a preset angle when the detection element detects the trademark paper 6.

The transmitter and receiver are respectively disposed close to the preset position. The height of the transmitter and receiver matches the height of the label paper 6. When the conveying member 11 has not conveyed the label paper 6 to the preset position, the receiver receives the signal emitted by the transmitter. When the conveying member 11 conveys the label paper 6 to the preset position, the label paper 6 will block the signal emitted by the transmitter, so that the receiver cannot receive the signal emitted by the transmitter. Then the controller determines that the receiver and transmitter have detected the label paper 6.
