TECHNICAL FIELD

[0001] The present application relates to the technical field of book saddle stitching products, and particularly relates to a knife seat installation mechanism controlled by air pressure. BACKGROUND

[0002] The three-side cutting book machine is one of the components in the binding production line. Paper needs to be printed, bound, cut, and then becomes a qualified finished product book. Cutting is one of the important steps, which is related to the size of the book and the quality of the finished product. The three-side cutting book machine is used for automatic movement, positioning, cutting and finished product output of the bound book during saddle stitching and adhesive binding. The most important thing in cutting the bound book is the positioning of the book and the knife. The knife is fixed on the knife seat. During factory production, equipment debugging or normal production process, the position of the side knife seat needs to be frequently adjusted to meet the requirements of the user. The position of the side knife seat needs to be higher during saddle stitching.

[0003] Therefore, a saddle stitching three-side cutting book machine appears on the market. The knife seat and the knife are fixed between the knife seat and the knife. Two long bolts and a pressing block are used to fix and install the knife seat on the cast aluminum knife holder. When adjusting the side knife, the uppermost bolt needs to be manually loosened. The existing knife seat fixing structure has the following problems: 1. During the frequent adjustment of the three-side cutting book machine, the required working hours and workload are large; 2. When the position of the knife seat needs to be adjusted during normal operation of the machine, the bolt needs to be loosened, which affects the use of the operator and is not convenient to use; 3. When replacing different types of book stickers, the position of the knife seat needs to be adjusted to change the cutting range, which affects the working efficiency of the adjustment personnel and the product yield. SUMMARY

[0004] In order to solve the problems in the prior art, the present application provides a new type of knife seat installation mechanism controlled by air pressure. The position of the bolt and the pressing block in the prior art is replaced by a pneumatic swing arm assembly, which can realize the functions of pneumatic clamping and loosening. During the adjustment process, the normal operation and use of the equipment are not affected, the workload of the workers is reduced, the quality of the products is good under normal working conditions, and the use is more convenient.

[0005] The technical problem solved by the present application is solved by the following scheme: a knife seat installation mechanism controlled by air pressure, comprising a knife seat and a knife holder, the knife seat and the knife holder are connected, the knife seat is provided with a pneumatic swing arm assembly for adjusting the position of the side knife, and the pneumatic swing arm assembly is arranged at the position where the knife seat and the knife holder are connected.

[0006] By adopting the above technical scheme, the pneumatic swing arm assembly is arranged in the mechanism, so that the fixed blade holder is not manually loosened during installation and debugging, the position of the blade holder is automatically adjusted by using the machine, the operation is convenient, the adjustment of the blade holder is more rapid and accurate, the workload of the operator is reduced, and the convenience during use is optimized.

[0007] Further, the pneumatic swing arm assembly comprises a blade holder fixing block, a pneumatic cylinder, a swing arm fixing frame, a disc spring mounting seat and a disc spring.

[0008] By adopting the above technical scheme, the blade holder fixing block and the swing arm fixing frame are fixedly connected and connected with the blade holder, so that the side blade, the blade holder and the blade holder mounting structure in the mechanism become an integral whole, and the normal operation of the machine is ensured during adjustment and operation.

[0009] Further, the pneumatic cylinder is mounted on the blade holder fixing block, the blade holder fixing block is provided with a mounting groove for mounting the pneumatic cylinder, the pneumatic cylinder is provided with a pneumatic cylinder push block, and the pneumatic cylinder push block is mounted on the pneumatic cylinder close to one side of the swing arm fixing frame.

[0010] By adopting the above technical scheme, the pneumatic cylinder push block can be pushed upward during operation of the pneumatic cylinder, which drives the nearby components to move, so that the components for adjustment are moved and adjusted, the automatic adjustment function is realized, and the normal operation of the machine is ensured.

[0011] Further, the swing arm fixing frame comprises a swing arm push rod, a swing arm and a swing arm connecting rod, the swing arm fixing frame is mounted on the upper end of the blade holder fixing block, the swing arms are symmetrically mounted on both sides of the swing arm fixing frame, the swing arm connecting rod is inserted into the swing arm fixing frame and connected with the swing arms, and the swing arm push rod is connected with the swing arms at both ends and arranged below the pneumatic cylinder push block.

[0012] By adopting the above technical scheme, the swing arm connecting rod serves as a fixed rotation center, and the swing arm push rod is arranged below the pneumatic cylinder push block, so that when the pneumatic cylinder drives the pneumatic cylinder push block to move, the swing arm push rod moves, and the swing arm rotates around the rotation center of the connecting rod.

[0013] Further, the disc spring mounting seat comprises an eccentric adjustment shaft and a disc spring fixing frame swing arm, the disc spring fixing frame swing arm is inserted into the disc spring mounting seat, the lower end of the disc spring fixing frame swing arm is connected with the swing arm, and the eccentric adjustment shaft is inserted into the disc spring fixing frame swing arm.

[0014] By adopting the above technical solution, when the cylinder is not supplying air, the disc spring mounting seat will be subjected to the elastic force of the disc spring, causing the disc spring mounting seat to fit against the cast aluminum tool holder, thereby forming an angle between the eccentric adjustment shaft, the disc spring fixing bracket swing arm and the swing arm connecting rod; when the cylinder supplies air, the disc spring mounting seat will be raised upwards, forming a gap with the cast aluminum tool holder, allowing the tool holder and mounting mechanism to be adjusted.

[0015] Furthermore, a disc spring connecting rod is installed above the swing arm fixing frame, the disc spring is connected to the disc spring connecting rod, and the disc spring is fixedly installed on the disc spring mounting base by bolts.

[0016] By adopting the above technical solution, the disc spring is installed on the disc spring mounting base with bolts, and the two are in close contact. The operation of the cylinder drives the disc spring to work, thereby changing its positional relationship with the cast aluminum tool holder.

[0017] Compared with the prior art, the beneficial effects of the present invention are: when using the mechanism for cutting work, the cutting range can be adjusted and changed only by controlling the cylinder button on the operating table, and the side blade holder can be clamped by operating the corresponding cylinder control button. In this process, the pneumatic mounting structure and the blade holder adjustment structure work together, making the operation process more convenient and more precise. Compared with the prior art, it achieves the function of quickly and efficiently adjusting and changing the cutting range, and the adjustment process is convenient and fast.

[0018] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.
