Description
Technical Field
[0001] The utility model relates to the technical field of printing devices, in particular to a printing device with a positioning structure. Background Technique
[0002] When a cardboard printing machine works, the characters and images to be printed are first made into printing plates and installed on the printing machine. Then, an operator operates the printing machine to evenly apply ink to the places with characters and images on the printing plate, and then directly or indirectly transfer them to corrugated cardboard or cartons, so as to reproduce the same printed replicas as the printing plates. The corrugated cardboard printing machine is one of the printing machines.
[0003] A set of clamps is arranged at the feeding place of the existing corrugated cardboard printing machine to continuously push the cardboard stacked at the center of the feeding place towards the center of the printing machine. However, the traditional clamps of the corrugated cardboard printing machine only push and position the front end of the cardboard. During the printing process, the following problems may occur: First, the cardboard moves. Under the action of the printing pressure, the rear half of the cardboard may move slightly, resulting in deviation of the printed pattern. Second, the printing is uneven. The unpositioned rear half may be affected by uneven force and affect the uniform adhesion of the ink, resulting in a decline in printing quality. Therefore, it is necessary to design a printing device with a positioning structure to solve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0025] Refer to Figures 1-4 , a printing device with a positioning structure, including a printing machine body 1 and a placement rack 2. The printing machine body 1 is equipped with a positioning fixture, which has been shown in the figure. Its working principle is prior art, so no further elaboration will be made. A mounting frame 3 is fixedly connected to the side wall of the placement rack 2. A driving mechanism for driving the cardboard to move is provided inside the mounting frame 3. The driving mechanism includes two vertical plates 5 arranged at the bottom inside the mounting frame 3. A positioning plate 6 is fixedly connected to the side wall of the vertical plate 5. A hydraulic cylinder 7 is provided on the side wall of the vertical plate 5, and a push plate 8 is installed at the output end of the hydraulic cylinder 7.
[0026] An adjusting mechanism for adjusting the position of the vertical plate 5 is provided on the mounting frame 3. The adjusting mechanism includes a double-headed screw 10 arranged on the side wall of the mounting frame 3, and a handwheel is fixedly connected to the side wall of the double-headed screw 10.
[0027] In the present utility model, a motor 11 is fixedly connected to the side wall of the placement rack 2. The output shaft of the motor 11 is connected to the double-headed screw 10 through a transmission mechanism, so that it is not necessary to manually rotate the double-headed screw 10, thereby improving the practicability of the device.
[0028] In the present utility model, the transmission mechanism includes a first gear fixedly connected to the output shaft of the motor 11 and a second gear fixedly connected to the side wall of the double-headed screw 10. The first gear and the second gear are meshed, which can make the double-headed screw 10 rotate more slowly and facilitate the adjustment of the position of the vertical plate 5.
[0029] In the present utility model, a control panel 9 is fixedly connected to the side wall of the placement rack 2. The motor 11 is a servo motor. The control panel 9 can control the rotation speed of the motor 11, making the double-headed screw 10 rotate more slowly and making it more convenient to adjust the position of the vertical plate 5.
[0030] In the present utility model, a placement groove is provided on the side wall of the placement rack 2, and a scale 4 is provided inside the placement groove. The width of the cardboard can be measured through the scale 4, so that the adjustment of the position of the vertical plate 5 is more accurate and there is no need for manual testing bit by bit.
[0031] In the present utility model, the push plate 8 is slidably connected to the adjacent positioning plate 6 to prevent the push plate 8 from bending due to the existence of gaps. The positioning plate 6 is made of stainless steel plate to ensure the structural strength of the positioning plate 6.
[0032] In the present utility model, both corners of the positioning plate 6 are rounded, and both corners of the pushing plate 8 are also rounded, which can prevent the operator from hurting the arm when putting a stack of cardboard.
[0033] In the present utility model, the two pushing plates 8 are symmetrically distributed relative to the central axis of the printing press body 1, and the two positioning plates 6 are also symmetrically distributed relative to the central axis of the printing press body 1, which can make the center of the cardboard located at the center of the printing press body 1 and ensure the printing quality.
[0034] During use, several stacks of cardboard are placed between the two positioning plates 6 first. The printing press body 1 is started, and the positioning fixture inside the printing press body 1 continuously positions the front part of the cardboard and continuously feeds the cardboard into the printing press body 1. The worker then places a small stack of cardboard on the cardboard stack between the two positioning plates 6 at a certain interval. The output ends of the two hydraulic cylinders 7 are started, and the two pushing plates 8 move towards each other to push this small stack of cardboard to the center of the printing press body 1 to complete the positioning. The positioning of the rear of the cardboard can be realized during the process, so that the positioning of the cardboard is more accurate.
[0035] In addition, for cardboard of different widths, by rotating the double-headed screw 10, the two vertical plates 5 move towards each other or in the opposite direction under the limit of the bottom of the installation frame 3, so that cardboard of different widths can be placed between the two positioning plates 6, thereby expanding the application range of the device.
[0036] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and practical concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
