Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines and relates to a high-speed printing machine. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding.

[0003] After printing, the ink on the paper will not dry up. It takes a while to dry the ink, which will affect the printing efficiency. The existing treatment method is usually to dry the printed paper with an electric heating rod to speed up the drying of the ink. However, when the staff cuts, rolls up, and disassembles the paper roll, the electric heating rod may affect the operation because it is set around the printed paper. In order to solve the impact of the electric heating rod on the staff's operation, a high-speed printing machine is proposed. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the utility model proposes a high-speed printing machine.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-speed printing machine comprises a base plate and a printing machine body, wherein the printing machine body is arranged on the rear side of the upper end surface of the base plate, a fixed plate is provided on the front side of the upper end surface of the base plate, a rotating roller is rotatably mounted on the fixed plate, a driving motor is fixedly connected to the fixed plate, the output end of the driving motor drives the rotating roller to rotate via an output shaft, an electric heating rod is provided directly above the rotating roller, a limiting plate is fixedly connected to the upper end surface of the base plate, one end of the electric heating rod is slidably arranged on the limiting plate, the other end of the electric heating rod is installed on a return mechanism, and the output shaft is drivingly connected to the return mechanism.

[0007] Furthermore, the return mechanism includes a one-way bearing fixedly connected to the outside of the output shaft and a half gear rotatably installed on the fixed plate. The outer ring of the one-way bearing is fixedly provided with a rotating gear, which cooperates with the half gear. A reset member is also installed between the half gear and the fixed plate. A lifting frame is fixedly installed on one end of the electric heating rod close to the half gear, and a translation axis is fixedly provided on the end face of the half gear, which slides with the lifting frame.

[0008] Furthermore, a rotating shaft is fixedly arranged on the fixed plate, and the half gear is rotatably mounted on the rotating shaft.

[0009] Furthermore, the reset member is a torsion spring, which is sleeved on the rotating shaft, one end of the torsion spring is fixed to the half gear, and the other end of the torsion spring is fixed to the fixed plate.

[0010] Furthermore, the width of the printing paper corresponds to the length of the electric heating rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The present invention sets an output shaft, and the initial position of the electric heating rod is located above the printing paper, and there is a certain distance between the two. When the ink on the printing paper needs to be dried, the output shaft is driven by the driving motor to rotate, and the electric heating rod is driven by the rotating gear and the half gear to move down. After the drying is completed and the driving motor is turned off, the electric heating rod will return to the initial position, which will not affect the staff's other operations on the printing paper, thereby improving the practicality of the present invention.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] like Figure 1-Figure 3 The technical solution adopted by the utility model is as follows: a high-speed printing machine, comprising a bottom plate 1 and a printing machine body 2. The printing machine body 2 is arranged on the rear side of the upper end surface of the bottom plate 1. A fixed plate 3 and a rotating roller 6 are arranged on the front side of the upper end surface of the bottom plate 1. The rotating roller 6 is rotatably arranged on the fixed plate 3. A driving motor 4 is fixedly connected to the fixed plate 3. The output end of the driving motor 4 and the axis center of the rotating roller 6 are fixedly connected with the same output shaft 5.

[0019] An electric heating rod 8 is provided directly above the rotating roller 6 .

[0020] The fixed plate 3 is also rotatably connected to a rotating shaft 11 on the side opposite to the rotating roller 6. The rotating shaft 11 is connected to the output shaft 5 via a return mechanism. The return mechanism includes a one-way bearing 16 fixedly connected to the outside of the output shaft 5. A rotating gear 15 is fixedly connected to the outside of the one-way bearing 16, and a half gear 12 is rotatably provided on the rotating shaft 11, and the rotating gear 15 is adapted to the half gear 12. A torsion spring 17 is sleeved on the outer wall of the rotating shaft 11, and the two ends of the torsion spring 17 are respectively fixedly connected to the half gear 12 and the fixed plate 3. Specifically, a rotating disc is rotatably connected to the rotating shaft 11, and a half gear 12 is fixedly provided on the outside of the rotating disc.

[0021] A translation shaft 13 is fixedly connected to a non-center portion of the rotating disk.

[0022] The upper end surface of the electric heating rod 8 is fixedly connected with a translation rod 9 , and the side of the translation rod 9 close to the rotating disk is fixedly connected with a lifting frame 14 , and the inner side wall of the lifting frame 14 is slidably connected to the translation shaft 13 .

[0023] The upper end surface of the bottom plate 1 is fixedly connected to a limit plate 10. The limit plate 10 is provided with a sliding groove perpendicular to the upper surface of the bottom plate 1, and the other end of the translation rod 9 is slidably connected to the inner wall of the sliding groove. The drive motor 4 is controlled by a switch, and when the drive motor 4 does not output power to the output shaft 5, the output shaft 5 cannot be rotated by external force;

[0024] The specific method is as follows: the driving motor 4 is turned on, and the driving motor 4 can drive the output shaft 5 to rotate, and then drive the rotating roller 6 to rotate, so that the printed paper 7 can be transmitted. When the output shaft 5 rotates, the output shaft 5 rotates through the one-way bearing to drive the rotating gear 15 to rotate. Under the action of the rotating gear 15, the rotating disk and the half gear 12 rotate half a circle. During the rotation of the half gear 12, the lifting frame 14 moves downward under the action of the translation shaft 13, so that the electric heating rod 8 is close to the top of the printing paper 7 to dry it.

[0025] After the driving motor 4 stops working, the rotating roller 6 stops rotating. At this time, the rotating disc and the half gear 12 rotate in the opposite direction under the action of the torsion spring 17. During the rotation of the half gear 12, the lifting frame 14 moves upward under the action of the translation shaft 13, thereby resetting the electric heating rod 8. Since the output shaft 5 and the rotating gear 15 are driven by a one-way bearing, when the half gear 12 rotates in the opposite direction, the one-way bearing will not drive the output shaft 5 to rotate.

[0026] This allows the electric heating rod 8 to be reset without affecting the operator's operation of cutting the printing paper 7 . Example

[0027] The printing paper 7 is delivered from the printing machine body 2 and is transmitted by the rotation of the rotating roller 6 . The width of the printing paper 7 corresponds to the length of the electric heating rod 8 .

[0028] This method is used to explain the transmission method of the printing paper 7, and is a supplementary explanation of the first embodiment.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
