[0020] like Figures 1 to 7As shown, a preheating reinforcement plate limiting structure of a printing press comprises a main body support connecting plate 1 in the horizontal direction, and an integrally formed mounting and fixing matching plate 2 is provided on the side of the main body support connecting plate 1, and the size of the outer side of the mounting and fixing matching plate 2 is smaller than the size of the side close to the main body support connecting plate 1, so that the matching operation during tightening is more convenient. The mounting and fixing matching plate 2 is provided with a main body fastening connection hole 3, which cooperates with the fastening screws to perform the overall tightening operation. The upper end of the main body support connecting plate 1 is provided with an integrally formed cylindrical limiting combination connecting column 4, and the upper center position of the limiting combination connecting column 4 is provided with a cylindrical main body avoidance ventilation hole 5 that penetrates the overall lower end surface, which can ensure better ventilation effects inside and outside during use, and can make the air circulation in the internal preheating chamber better during the preheating process, and the preheating efficiency is higher. The upper end of the limit combination connecting column 4 is provided with a limit matching placement groove 6 which opens upward and is evenly distributed around the circumference, and can be matched with different preheating plates, making it more convenient to install multiple groups of preheating plates, with better position accuracy between each other, and higher safety during later use. The width of the upper end position of the limit matching placement groove 6 is greater than the width of the lower end position, and the placement operation during matching is easier, and no precise alignment is required. The limit matching placement groove 6 penetrates the main body avoidance ventilation hole 5 and the outer side of the limit combination connecting column 4. It adopts a brand-new structural design, which can be fixed by a single fastening screw during installation. The main body position can be accurately and stably matched and connected for multiple groups of heating plates. On the one hand, it improves the efficiency during installation and matching, and on the other hand, it can ensure the assembly accuracy of the heating plate, better safety during use, and can ensure higher efficiency and better preheating uniformity around, and the overall heat utilization rate during use is higher.

[0021] Preferably, the thickness of the main support connecting plate 1 is the same as the thickness of the mounting and fixing matching plate 2, so that the flatness of the main structure is better, the structural strength can be further improved, and it is more convenient to produce and process.

[0022] Preferably, the connection position of the mounting and fixing fitting plate 2 and the main body supporting connecting plate 1 is connected together through a transition fitting arc structure, so that the structural strength of the connection position is better.

[0023] Preferably, the main structure of the main body supporting connecting plate 1 is also a cylindrical structure, and is identical to the central axis of the position-limiting combination connecting column 4, so that the right side is used as the assembly position when the main body is matched, and the structural bearing strength is more reliable.

[0024] Preferably, the depth of the limit fitting placement groove 6 is greater than two-thirds of the height of the limit combination connecting column 4, so that the combination stability during limit fitting is more reliable. If the depth is too small, it will occupy a relatively large space and will also affect the combination strength of the fitting position.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
