[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] In order to extend the service life of the printing machine, a shell needs to be installed on the outside of the printing machine to prevent external forces from directly colliding with the printing machine. In the existing technology, the shell is installed on the outside of the printing machine, fixed by bolts around, and then the shell and the printing machine base are welded by electric welding. This operation is convenient and fast. However, after using the printing machine for a long time, when the shell needs to be repaired and replaced, it is necessary to use auxiliary tools to remove the bolts and cut the welding part, which greatly increases the workload.

[0004] Therefore, it is particularly important to improve the existing printing machine heat dissipation housing, design a new printing machine heat dissipation housing to solve the above technical defects, and improve the practicality of the overall printing machine heat dissipation housing.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A heat dissipation housing of a printing machine comprises a fixing frame 1, a machine body 2 is mounted on the top of the fixing frame 1, a housing 3 is mounted outside the machine body 2, a groove 4 is formed on the top of the housing 3, a visible transparent cover is mounted inside the groove 4, a through slot 5 is formed on the front of the housing 3, an extended edge 6 is mounted on the bottom end of the housing 3, and a disassembly assembly 7 is mounted inside the extended edge 6;

[0026] The disassembly assembly 7 is used to quickly complete the installation and disassembly between the housing 3 and the machine body 2

[0027] For further information, see Figure 2 and Figure 3In this embodiment, the disassembly assembly 7 includes a nut 701, a cylinder 702, a threaded column 703, an extrusion block 704, a circular groove 705 and a rolling ball 706. The nut 701 is installed on the top of the extended edge 6, the cylinder 702 is installed on the bottom of the nut 701, the threaded column 703 is installed inside the cylinder 702, the extrusion block 704 is installed below the threaded column 703, the circular groove 705 is symmetrically opened inside the cylinder 702, and the rolling ball 706 is installed inside the circular groove 705. At present, when the existing machine body 2 is in use, it is necessary to set a layer of shell 3 on it, which effectively controls the machine body 2. The service life is extended. When the shell 3 needs to be repaired after being used for a long time, the threaded column 703 is rotated by turning the nut 701, so that the threaded column 703 completes the rising work inside the cylinder 702. At the same time, the extrusion block 704 will move with the threaded column 703, so that there is no obstruction outside the circular groove 705, and the extrusion block 704 releases the fixation of the ball 706, so that the ball 706 completely falls into the interior of the circular groove 705, thereby releasing the fixation between the shell 3 and the fixing frame 1, and realizing the rapid separation between the shell 3 and the fixing frame 1.

[0028] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, a placement groove is provided inside the fixing frame 1 at a position corresponding to the cylinder 702, and the cylinder 702 is connected to the fixing frame 1 through the placement groove. A receiving groove is provided inside the placement groove at a position corresponding to the rolling ball 706. Through the design of the placement groove, the cylinder 702 is inserted into the placement groove to complete the connection between the extended edge 6 and the fixing frame 1. The rolling ball 706 is inserted into the receiving groove to fix the cylinder 702, thereby realizing quick installation between the shell 3 and the fixing frame 1.

[0029] Furthermore, please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a thread groove 707 is provided on the inner wall of the cylinder 702 at a position corresponding to the thread column 703, and a spring 708 is installed between the thread column 703 and the extrusion block 704. Through the design of the thread groove 707, the thread column 703 can react with the thread groove 707 when rotating, so as to realize the uniform rising or falling movement of the thread column 703 inside the cylinder 702. Through the expansion and contraction energy storage of the spring 708, the thread column 703 can squeeze the spring 708 when descending, drive the extrusion block 704 to descend, and block the circular groove 705 through the extrusion block 704, thereby squeezing the ball 706, so that the ball 706 enters the interior of the receiving groove.

[0030] Furthermore, please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the extrusion block 704 is designed in a trumpet-shaped structure, and a connecting ear 709 is installed on the top of the nut 701. The connecting ear 709 extends to the inside of the cylinder 702, and the connection between the connecting ear 709 and the threaded column 703 is a fixed connection. Through the design of the connecting ear 709, it is easier to rotate the threaded column 703.

[0031] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, heat dissipation fins 8 are installed on the left and right sides and the back of the outer shell 3, a square groove is opened on the inner wall of the outer shell 3, and filter screens 9 are installed on the left and right sides and the back of the inner shell 3. Through the design of the heat dissipation fins 8 and the filter screen 9, the interiors are interconnected, so that the outside air can better enter the interior of the outer shell 3, thereby cooling the machine body 2 and preventing the machine body 2 from being overloaded by high temperature and affecting the working efficiency.

[0032] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, a cooler 10 and a circulating pump 11 are respectively provided between the heat dissipation fins 8 and the filter screen 9, a connecting pipe 12 is installed between the cooler 10 and the circulating pump 11, a first refrigeration pipe 13 is installed on the left side of the cooler 10, and a second refrigeration pipe 14 is installed on the right side of the circulating pump 11. By adding refrigerant into the cooler 10 and starting the circulating pump 11, the refrigerant flows into the circulating pump 11 through the connecting pipe 12, and then flows into the second refrigeration pipe 14 and the first refrigeration pipe 13, so as to cool the machine body 2. Then, through the design of the heat dissipation fins 8 and the filter screen 9, the outside air enters the interior of the shell 3, thereby cooling the cooler 10 and the circulating pump 11.

[0033] In this embodiment, the implementation scenario is specifically as follows: when the existing machine body 2 is in use, it is necessary to cover it with a shell 3 to effectively extend the service life of the machine body 2. When the shell 3 needs to be installed after a long period of use, the connection between the extended edge 6 and the fixing frame 1 is completed by inserting the cylinder 702 into the placement groove, and the threaded column 703 is driven to rotate by rotating the connecting ear 709. Through the design of the thread groove 707, the threaded column 703 can react with the thread groove 707 when rotating, so as to realize the uniform downward movement of the threaded column 703 inside the cylinder 702. Through the expansion and contraction energy storage of the spring 708, the threaded column 703 can squeeze the spring 708 when descending. The extrusion block 704 is driven to descend, and the circular groove 705 is blocked by the extrusion block 704, so as to squeeze the ball 706, so that the ball 706 enters the interior of the receiving groove, and the cylinder 702 is fixed, and then the nut 701 is driven to fit tightly with the extension edge 6, so as to achieve rapid installation between the shell 3 and the fixing frame 1, and the refrigerant is added to the interior of the cooler 10 and the circulation pump 11 is started, so that the refrigerant flows into the interior of the circulation pump 11 through the connecting pipe 12, and then flows to the interior of the second refrigeration pipe 14 and the first refrigeration pipe 13, so as to cool the machine body 2, and then the design of the heat dissipation fins 8 and the filter screen 9 allows the outside air to enter the interior of the shell 3, so as to cool the cooler 10 and the circulation pump 11.
