[0002] As a key device in the modern printing field, digital printing machines are increasingly widely used in the printing industry. As the core component of the control system of a digital printing machine, the board plays a decisive role in the stable operation of the device.

[0003] At present, most digital printing machines fix the board in the device through screws. This installation method has many disadvantages. On the one hand, the installation and disassembly processes are cumbersome. Every time maintenance, upgrade or replacement of the board is required, the staff needs to use tools for disassembly and assembly, which is time-consuming and laborious. On the other hand, the current screw installation method limits the heat dissipation space of the board and lacks an effective heat dissipation structure. It is difficult for the heat of the board to dissipate quickly, which will not only accelerate the aging of electronic components on the board, shorten the service life of the board, but also may cause abnormal performance of electronic components, resulting in problems such as printing color deviation and inaccurate overprinting, seriously affecting the printing quality.

[0006] Preferably, bending sections are respectively provided at the left and right edges of the bracket. A pair of round holes for accommodating the screws are provided on the bending sections, and reinforcing ribs are integrally formed on the bending sections.

[0007] Preferably, mounting ears are integrally formed on both sides of the inner concave part respectively, and the heat dissipation plate is fixedly installed between a pair of the mounting ears.

[0008] Preferably, the limit member is assembled by a pressing plate, a sliding rod and a plug rod. The sliding rod penetrates through the bracket and is screwed with a nut. The elastic member is a spring sleeved on the sliding rod. The two ends of the spring are respectively in contact with the nut and the bracket. A plurality of jacks for accommodating the plug rod are provided along the diagonal of the inner concave part.

[0009] Preferably, the concave portion is provided with an opening for accommodating the heat dissipation plate, and a through hole is provided above the opening.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a board mounting bracket for a digital printing press, including a bracket 1, a heat dissipation plate 3 and screws 6. An inner concave portion 2 for accommodating the board is integrally formed at the central position of the bracket 1. The inner concave portion 2 is adapted to the size of the board. Installation ears 12 are integrally formed on both sides of the inner concave portion 2. The heat dissipation plate 3 is fixedly installed between a pair of installation ears 12. The inner concave portion 2 is provided with an opening for accommodating the heat dissipation plate 3. After the board is installed in the inner concave portion 2, it contacts the heat dissipation plate 3, effectively increasing the heat dissipation area, allowing heat to be dissipated more quickly into the surrounding air, preventing the board from deteriorating in performance, malfunctioning or even being damaged due to overheating, and ensuring the stable operation of the board. The inner concave portion 2 is provided with a through hole 11 above the opening. The advantage of this setting is that while saving materials, the bracket 1 is made lightweight.

[0024] Please refer to Figure 1 , bending sections 4 are respectively provided at the left and right edges of the bracket 1. A pair of round holes for accommodating the screws 6 are provided on the bending sections 4. The bracket 1 is installed in the printing press control box through the screws 6. The board (prior art, not shown in the figure) is connected to other components such as a power supply, a motor driver, a sensor, etc. through connecting wires to facilitate the centralized control and management of various functions of the printing press. Reinforcing ribs 5 are integrally formed on the bending sections 4. The reinforcing ribs 5 can increase the thickness and rigidity of the bending part, enabling it to withstand greater external forces. The corners of the bracket 1 are all smoothly transitioned with rounded corners. The rounded corners can eliminate sharp corners and reduce the risk of personnel being scratched when installing the bracket 1. Limiting members are respectively slidably installed at the four corners of the bracket 1 through elastic members, so that the board can be installed in the inner concave portion 2 through the cooperation of the limiting members and the elastic members. The installation of the elastic members and the limiting members does not require additional tools to disassemble and install the board. Compared with screw installation, the installation time is greatly saved.

[0025] Please refer to Figures 2 - 7 , the limiting member is assembled by a pressing plate 7, a sliding rod 8 and a plug rod 10. The sliding rod 8 penetrates the bracket 1 and is screwed with a nut. The elastic member is a spring 9 sleeved on the sliding rod 8. The two ends of the spring 9 are respectively in contact with the nut and the bracket 1. A plurality of jacks for accommodating the plug rod 10 are provided along the diagonal of the inner concave portion 2. It is worth mentioning that the positions of the jacks correspond to the through holes provided on the board in the prior art. A convex rib is provided on one side of the pressing plate 7. The advantage of this setting is to increase the friction with the fingers.

[0026] When the board and the bracket 1 need to be assembled, first push the slide bar 8 forward and drive the plug rod 10 out of the socket through the pressure plate 7, then move the pressure plate 7 so that the pressure plate 7 rotates around the slide bar 8 until the plug rod 10 is away from the inner recess 2, then place the board in the inner recess 2, rotate the pressure plate 7 until the plug rod 10 passes through the through hole of the board and the socket of the inner recess 2 with the cooperation of the spring 9, and the installation is completed. By installing the heat sink 3 on one side of the bracket 1, the heat dissipation area of ​​the board is increased, and the stable operation of the board is maintained. The cooperation between the limiter and the elastic member effectively simplifies the board installation steps, has a simple structure, is easy to operate, and improves the board installation efficiency, saving a lot of time and cost for daily maintenance of digital printing machines, board replacement, etc.
