Description

Technical Field

[0001] The utility model relates to the field of printing equipment, in particular to a conveying table for printing express delivery labels. Background Art

[0002] An express delivery label is a document used by the express delivery industry to record information such as the sender, recipient, product weight, and price during the delivery process. During the production process, the express delivery label is pre-printed with the express delivery logo and other graphic symbols such as a wireframe. Upon use, the order number and personal information are printed in the corresponding area.

[0003] During the production process of express delivery labels, the printing step usually uses a flexographic printing press for large-scale printing. In order to ensure the quality of printing, it is necessary to ensure that the face sheet paper is always aligned with the printing roller and is conveyed into the printing roller. Therefore, a correction mechanism needs to be set on the conveyor table. However, the size of the existing correction mechanism is adapted to the width of the face sheet paper. When replacing face sheet paper of different widths for printing, it is necessary to replace the correction mechanism of different sizes, which makes the conveyor table inconvenient to use.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See also Figure 1-Figure 4 The present embodiment provides a conveyor platform for printing express delivery labels, including a platform 1, a correction mechanism 2 and a printing mechanism 4. The correction mechanism 2 and the printing mechanism 4 are both arranged on the platform 1, and the correction mechanism 2 is arranged on the left side of the printing mechanism 4. The correction mechanism 2 includes a guide roller 21 with adjustable length, and the front and rear ends of the guide roller 21 are provided with baffles 22 with a diameter larger than the guide roller 21.

[0021] In the present invention, the printing mechanism 4 adopts a conventional flexographic printing mechanism, and its working principle will not be described in detail in this specification.

[0022] When the present invention is in use, the distance between the baffles 22 on both sides of the guide roller 21 is adapted to the width of the single-face paper, so that the front and rear positions of the single-face paper are limited on the guide roller 21, and at the same time the guide roller 21 is aligned with the printing position in the printing mechanism 4, so that the offset of the single-face paper transported to the printing mechanism 4 is reduced by the correction mechanism 2, thereby improving the printing quality, and by adjusting the length of the guide roller 21 to adapt to single-face paper of different widths, the present invention can be applied to single-face paper of different widths within a certain range, thereby improving the scope of application of the present invention and improving the convenience of use of the present invention.

[0023] See also Figure 2 The correction mechanism 2 also includes a base 23 and a slide rail 24. The base 23 is fixed on the base 1, and the slide rail 24 is fixed on the base 23. Two sliders 25 are provided on the slide rail 24 to slide in the front and back directions. The front and rear ends of the guide roller 21 are respectively rotatably connected to the two sliders 25. A first motor 26 for driving the slider 25 to move is provided on the base 23, and a second motor 27 for driving the guide roller 21 to rotate is provided on the slider 25.

[0024] In the present invention, the first motor 26 adopts a screw rod 30 motor to drive the slider 25 to move linearly along the slide rail 24. The movement of the two sliders 25 drives the front and rear ends of the guide roller 21 to separate from or approach each other, and the guide roller 21 is extended and retracted to adjust the length of the guide roller 21. The second motor 27 drives the guide roller 21 to rotate on the base 23, thereby reducing the friction between the guide roller 21 and the single-sided paper, and at the same time provides a certain power for the transportation of the single-sided paper, ensuring that the single-sided paper is continuously transported to the right into the printing mechanism 4.

[0025] See also Figure 2-Figure 4The guide roller 21 includes two plug-in rods 28, one end of the plug-in rod 28 is rotatably set on the base 23 through a bearing, and the other end of the plug-in rod 28 is circular and has three fan-shaped cross-section posts 29 at equal intervals. The posts 29 on the two plug-in rods 28 are plugged in by staggered sliding.

[0026] By means of the fitting sliding connection between the adjacent plug posts 29 on the two connecting rods 28, it is ensured that the plug posts 29 can support the facing single paper while realizing the mutual insertion and separation between the two connecting rods 28, thereby realizing the shortening and elongation of the guide roller 21. The adjacent plug posts 29 can support each other, reducing the downward offset of the middle position of the guide roller 21 under the action of gravity, so that the guide roller 21 can maintain a straight state, thereby ensuring the supporting effect of the guide roller 21 on the facing single paper.

[0027] See also Figure 3 A screw rod 30 is coaxially fixed to the rotating shaft of the first motor 26. The screw rod 30 is provided with two thread segments with opposite thread directions. The two sliders 25 are respectively threadedly connected to the two thread segments.

[0028] The screw rod 30 is driven to rotate by the first motor 26. Since the two sliders 25 are respectively located on two threaded segments with opposite thread directions on the screw rod 30, when the screw rod 30 rotates, the two sliders 25 move in opposite directions to move closer or farther away. The simultaneous movement of the two sliders 25 is achieved by a single driving device, which can reduce the complexity of the structure of the utility model and improve the convenience of manufacturing and maintenance of the utility model.

[0029] See also Figure 2 、 Figure 3 There are two guide rollers 21 and they are arranged on the base 23 to rotate side by side left and right. There are two slide rails 24 and they are respectively located below the two guide rollers 21.

[0030] The first motor 26 drives the slider 25 to move and adjust the length of the two guide rollers 21 at the same time. The single-sided paper is wound on the two guide rollers 21. The two guide rollers 21 are used to limit the single-sided paper, thereby improving the accuracy of correcting the deviation of the single-sided paper. The two slide rails 24 can improve the stability of the slider 25 on the slide rail 24, thereby reducing the risk of the equipment shaking during the operation of the present invention causing the slider 25 to deviate, thereby affecting the correction function of the guide roller 21.

[0031] See also Figure 2 、 Figure 3 A flattening roller 5 is provided on the left side of the guide roller 21. The flattening roller 5 is rotated by a third motor 51 and is arranged on the base 23. Two spiral protrusions 52 with opposite spiral directions are provided on the surface of the flattening roller 5.

[0032] The single-sided paper is wound on the flattening roller 5, and the flattening roller 5 is driven to rotate by the third motor 51. The spiral protrusion 52 on the flattening roller 5 drives the single-sided paper to unfold to the front and back sides thereof, thereby reducing the probability of curling of the single-sided paper during the transportation process. After the single-sided paper is flattened, it is corrected by the guide roller 21, thereby ensuring the accuracy of the position of the single-sided paper and improving the printing quality of the single-sided paper.

[0033] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
