Description

Technical Field

[0001] The utility model relates to the technical field of printing paper receiving machines, in particular to a paper receiving machine for a printing press. Background Art

[0002] A printing press is a machine for printing characters and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, impression, and paper feeding (including folding). Its working principle is as follows: First, the characters and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with characters and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates to reproduce the same printed matter as the printing plate. The invention and development of printing presses play an important role in the spread of human civilization and culture. Existing intelligent printing presses are also called printers. Sometimes they print by connecting to documents. The number of printed papers is relatively large. Generally, the paper receiving position is a platform, and too many papers cannot be stacked. Moreover, after multiple document prints, they will be stacked together and need to be separated later. If the number of papers in each printed document is not large, it is convenient to separate them manually. However, when printing a project book or other document with hundreds of pages, people often need to stand beside the printer. Otherwise, too many papers will crush the paper receiving board, and it is also troublesome to separate them later. Therefore, there is a need for a paper receiving machine that can store hundreds or even thousands of printed papers and can automatically separate and store the papers printed from multiple documents.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0018] Referring to Figures 1-3 , a delivery apparatus for a printing press, comprising a control box 1, lifting columns 2, a mounting frame, a delivery board 4, a delivery board lifting mechanism and a delivery board placing mechanism. A controller 13 is provided at the bottom inside the control box 1, and a height adjustment assembly is provided above the controller 13. The bottom of the lifting column 2 is movably inserted into the control box 1 and mounted on the height adjustment assembly. The mounting frame includes a bottom plate 3, a top plate 32 and support rods 31 connecting the four corners between the bottom plate 3 and the top plate 32. The lower surface of the bottom plate 3 is fixed to the top of the lifting column 2. Four limit slide rods 7 distributed in a square shape are provided between the bottom plate 3 and the top plate 32 inside the four support rods 31. A plurality of delivery boards 4 are sleeved on the four limit slide rods 7. Two groups of the delivery board lifting mechanisms are symmetrically arranged on both sides of the delivery board 4. The delivery board lifting mechanism includes a lifting block 6, a first pushing cylinder, a first connecting plate 61, two vertical moving slide rods 52, a lifting lead screw 51 and a synchronous servo motor 5. The two vertical moving slide rods 52 are parallelly mounted between the bottom plate 3 and the top plate 32. A first pushing cylinder is provided inside the lifting block 6, and the cylinder shaft of the first pushing cylinder faces inward and a first connecting plate 61 is provided on the cylinder shaft. The lifting block 6 is sleeved on the two vertical moving slide rods 52 near both side positions, and the lifting lead screw 51 spirally penetrates through the middle position of the lifting block 6. Both ends of the lifting lead screw 51 are sleeved with bearings and the bearings are embedded in the bottom plate 3 and the top plate 32. The synchronous servo motor 5 is mounted on the top plate 32 and the motor shaft is connected to the top end of the lifting lead screw 51. The delivery board placing mechanism includes a plurality of empty delivery board placing units 311 and a plurality of papered delivery board placing units 312. The empty delivery board placing unit 311 and the papered delivery board placing unit 312 have the same structure. The empty delivery board placing unit 311 includes four second pushing cylinders respectively mounted on each support column on the same horizontal plane, and a second connecting plate is provided at the end of the cylinder shaft of the second pushing cylinder. An inlet paper slide plate 8 is provided at the position between the lowermost empty delivery board placing unit 311 and the uppermost papered delivery board placing unit 312 on the front side of the mounting frame. A data line interface 12, a power cord 11 and a plug are provided on one side of the control box 1.

[0019] The empty cardboard collecting and placing unit 311 and multiple groups of cardboard collecting and placing units 312 with cardboard are correspondingly numbered and connected to the controller through wires. The controller 13 controls the second push cylinder to correspondingly extend the second supporting plate. The specific operation is as follows: At the beginning, all the cardboard collecting plates 4 are all on the empty cardboard collecting and placing unit 311. When printing the first document, the cardboard collecting plate lifting mechanism moves the lifting blocks 6 on both sides to both sides of the bottommost cardboard collecting plate 4, and starts the two first push cylinders in the lifting blocks 6 to synchronously move the first supporting plate 61 to the lower part of the middle position between both sides of the cardboard collecting plate 4 (the cylinder shafts of all push cylinders are square columns to prevent them from rotating). At this time, the second push cylinder on the corresponding empty cardboard collecting and placing unit 311 retracts the second supporting plate, and the second supporting plate no longer supports the cardboard collecting plate 4. By moving the lifting block 6 downward, the cardboard collecting plate 4 is moved to a position slightly below the paper feeding slide plate 8, and the printing paper slides from the paper feeding slide plate 8 into the cardboard collecting plate 4. After collecting the printing paper of one document, the first cardboard collecting plate 4 is moved to the bottommost cardboard collecting and placing unit 312 with cardboard (the operation is the same as that of the empty cardboard collecting and placing unit 311, and the second push cylinder extends the second supporting plate to support the bottom of the cardboard collecting plate). The printing of other documents is the same as its operation, and all are connected to the controller, and the controller is connected to the printer through the data cable interface. When the printer switches the printed document, the cardboard collecting plate 4 is switched. The four second supporting plates at the ends of the cylinder shafts of the second push cylinders in the same group are simultaneously located at the four corners below the cardboard collecting plate or leave simultaneously.

[0020] The distance between adjacent empty cardboard collecting and placing units 311 is 1.2 - 1.5 times the thickness of the cardboard collecting plate 4, and the distance between adjacent cardboard collecting and placing units 312 with cardboard is 2.5 - 3.5 times the thickness of the cardboard collecting plate 4.

[0021] Since the cardboard collecting plate 4 on the empty cardboard collecting and placing unit 311 does not need to store paper, a small space can be left between the cardboard collecting plates 4 when placing them, but enough space should be maintained after storing the cardboard collecting plate 4 with paper to facilitate taking out the paper later.

[0022] The number of empty cardboard collecting and placing units 311 is the same as the number of cardboard collecting and placing units 312 with cardboard, and the number of empty cardboard collecting and placing units 311 is not less than 3 but not more than 6.

[0023] It is possible to collect and store the paper for continuous printing of not less than three documents. If there are too many, the height will be relatively high and the weight will also be relatively heavy, which is inconvenient for operation. Generally, 4 - 5 are the best.

[0024] The height adjustment component includes a height adjustment servo motor 14 and a height adjustment lead screw 141. The shaft of the height adjustment servo motor 14 faces upward and the bottom end of the height adjustment lead screw 141 is connected to the motor shaft. The height adjustment lead screw 141 is spirally inserted from the center position at the bottom of the lifting column 2. It can be finely adjusted (adjusted within the range of 10 - 15 cm) to optimally use the paper outlet.

[0025] The upper surface of the paper receiving board 4 is provided with a storage cavity, and the inner side wall of the front side wall of the paper receiving board 4 is an inclined inner side wall 41 facing downwards, which is convenient for the paper to slide down.

[0026] The paper inlet slide plate 8 inclines downwards towards the inside of the mounting frame, and the inclination angle is between 30° and 45°. After the paper is ejected, it can smoothly slide into the paper receiving board 4.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
