Description
Technical Field
The utility model relates to the field of printing technology, especially, relate to a lithography apparatus is with pressing paper device.
Background
The printing machine is generally composed of mechanisms for plate loading, inking, stamping, paper conveying, folding and the like. The working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred onto paper or other printing material, so that the same printed matter as that of the printing plate can be reproduced.
The printing machine needs to place paper on the printing platform before printing the paper, and the conveying platform for conveying the paper carries the paper to the position of the printing roller for printing under the driving action of the driving belt. In order to reduce problems such as printing misalignment due to paper lifting, it is necessary to press or level the paper during printing.
In the prior art, the method for compressing paper commonly used adopts the cylinder to directly and vertically press down the paper, and when the paper per se is relatively flat, the mode of vertically pressing down the paper through the cylinder can meet the requirement. However, when the paper has large unevenness or wrinkles, the portion of the paper between the printing roller and the cylinder may be raised when the cylinder presses the paper, which may cause a misalignment of the paper printing or a jam. Therefore, there is room for improvement. And sometimes the paper is charged with static electricity during printing, which is not beneficial to printing.
Disclosure of Invention
In order to overcome the not enough among the prior art, the utility model provides a printing apparatus is with pressing paper device, its constitution includes the conveyer belt, its characterized in that: the utility model discloses a conveying belt, including conveyer belt, stand one, blank pressing wheel support arm swing joint, middle-lower part and the conveyer belt of blank pressing wheel support arm, the middle-upper portion of stand one and blank pressing wheel support arm is parallel, and wherein the lower part evenly is provided with a plurality of blank pressing wheels, spring coupling is passed through on the middle-upper portion of stand one and blank pressing wheel support arm, the right-hand member bilateral symmetry fixed mounting of conveyer belt has stand two, the top and the rolling wheel support swing joint of stand two, the rolling wheel support is the rectangle, and its bottom evenly is provided with the recess, be provided with the rolling wheel in the recess, the bilateral symmetry fixed mounting that the conveyer belt is located between stand one and the stand two has stand three, install the pressure paper wheel between the stand three.
In order to remove static electricity of paper, the paper pressing wheel can be of a hollow structure, air holes are uniformly formed in the outer surface of the paper pressing wheel, and the inner space of the paper pressing wheel is connected with the ion fan.
The utility model has the advantages that:
1. the utility model discloses a both sides of paper are pushed down to the crimping wheel, are pressing the combined action of paper wheel through the crimping, can press more level of paper, can effectively prevent the paper fold simultaneously, do benefit to and improve printing speed.
2. The utility model discloses the combined action of ion fan and pressure paper wheel can effectively get rid of the static on the paper, has improved the quality of printing.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of the rolling wheel support of the present invention.
Fig. 3 is a schematic view of the structure of the platen.
In the figure: the device comprises a conveyor belt 1, a second upright post 2, a rolling wheel bracket 3, a third upright post 4, a paper pressing wheel 5, a blank pressing wheel 6, a blank pressing wheel support arm 7, a spring 8, a first upright post 9, a groove 31, a rolling wheel 32 and an air hole 51.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1 and 3, a platen device for a printing apparatus, which is composed of a conveyor belt 1, is characterized in that: the utility model discloses a conveying belt, including conveyer belt 1, stand 1, blank pressing wheel support arm 7, spring 8, stand 9 and blank pressing wheel support arm 7, the well lower part of blank pressing wheel support arm 7 is parallel with conveyer belt 1, and wherein the lower part evenly is provided with a plurality of blank pressing wheels 6, the well upper portion of stand 9 and blank pressing wheel support arm 7 is passed through spring 8 and is connected, the right-hand member bilateral symmetry fixed mounting of conveyer belt 1 has stand two 2, the top and the 3 swing joint of rolling wheel support of stand two 2, rolling wheel support 3 is the rectangle, and evenly is provided with recess 31 in its bottom, be provided with rolling wheel 32 in the recess 31, the bilateral symmetry fixed mounting that conveyer belt 1 is located between stand one 9 and the stand two 2 has stand three 4, install between stand three 4 and press paper 5.
The paper pressing wheel 5 can be a hollow structure, air holes 51 are uniformly formed in the outer surface of the paper pressing wheel, and the inner space of the paper pressing wheel 5 is connected with the ion fan.
During operation, draw the paper in proper order and press limit wheel 6, press paper wheel 5 and rolling wheel 32, start conveyer belt 1, the paper can be sent into the printing machine and print, in order to prevent that static from influencing the printing effect, can start the ion fan, and the wind of ion fan can be pressed the air pocket 51 of paper wheel 5 altogether and flow out, and then gets rid of the static on paper surface, improves printing quality. Meanwhile, the paper pressing wheel 5 and the rolling wheel 32 have the combined action, so that the middle of the paper can be effectively prevented from wrinkling, the printing quality is improved, and the printing efficiency is improved.
