[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the locking state of the pneumatic claw-type locking mechanism of the double-bed bag-shaking chamber of the medicinal fluidized bed granulation dryer. Figure 2It is a structural diagram of the cylinder fixing plate 4. The utility model provides a pneumatic claw-type locking mechanism for the double-bed bag-shaking chamber of a medicinal fluidized bed granulation dryer: it is applied to a boiling bed body 7, and a hanger device 8 is installed on the boiling bed body 7. It also includes a claw-type locking device, and the claw-type locking device includes an actuating cylinder 6, a cylinder fixing plate 4, a claw body 1 and an elastic member 5. The hanger device 8 is provided with a support rod 2 and a support rod sleeve 3. The support rod 2 is provided with a plurality of cylindrical pins, and the cylindrical pins slide in cooperation with the claw body 1. The outer surface of the support rod 2 and the inner sliding cavity surface of the support rod sleeve 3 are respectively provided with a wear-resistant coating, and the elastic member 5 is a coil spring. The above scheme can realize the rapid locking of the fluidized bed bag-shaking hanger. It can be understood that the above scheme can realize the rapid locking of the automatic fluidized bed bag-shaking hanger, which is more convenient for use.

[0018] In this embodiment, the claw-type locking device is arranged on one side of the hanger device 8, and the claw-type locking device is used to achieve rapid locking of the fluidized bed bag shaking hanger.

[0019] Wherein, the actuating cylinder 6 is detachably connected to the hanger device 8 and the cylinder fixing plate 4 respectively, and is located on one side of the cylinder fixing plate 4. The claw body 1 is arranged on the side of the actuating cylinder 6 away from the cylinder fixing plate 4, and the elastic member 5 is arranged between the claw body 1 and the cylinder fixing plate 4. The actuating cylinder 6 is fixed to the mounting portion of the hanger device 8 by bolts, and the output end of the actuating cylinder 6 is arranged as a stepped external thread end, and a circular through hole is arranged on the cylinder fixing plate 4. When installing, it is passed through the stepped output end of the actuating cylinder 6 and then locked and fixed by a nut. Guide rods are arranged on both sides of the claw body 1, and the guide rods are slidably matched with the through holes on the hanger device 8. Then, the guide rods are fixed on both sides of the cylinder fixing plate 4 by nuts. A plurality of U-shaped grooves are arranged on the claw body 1 to form a claw structure, which is convenient for The hanger device 8 is used for cooperative clamping, and the elastic member 5 is directly sleeved on the guide rod. The function of the elastic member 5 is to help the actuating cylinder 6 quickly reach the locking position when the actuating cylinder 6 is locked, thereby realizing rapid locking. The actuating cylinder 6 adopts a single-rod cylinder. The single-rod cylinder is a simple pneumatic transmission element, and its structure mainly consists of four parts: a cylinder barrel, a piston, a rod and a sealing device. The cylinder barrel is directly connected to the air source pipeline when working. Due to the existence of the rod, the piston can make reciprocating motion in the cylinder, thereby driving the connected external mechanical element to move. In the equilibrium position, the sealing ring can effectively prevent air pressure leakage and ensure the stability and safety of the system operation. The advantages of using a single-rod cylinder are: 1. Simple structure: The single-rod cylinder has a simple structure. Since it does not require a complex guide mechanism, the rod head can be directly connected to the transmitted element, so it is small in size and light in weight, and is suitable for occasions with narrow space. 2. Stable use: The single-rod cylinder has a smooth movement, high reliability and long service life. It has good sealing performance, stable air pressure, can withstand large loads, and is not prone to malfunctions due to the accumulation of foreign matter such as impurities. 3. Easy maintenance: Due to the simple structure of the single-rod cylinder, it is relatively easy to disassemble and replace during maintenance. During maintenance, only damaged seals and fatigued springs need to be replaced, which is simple and time-saving. Therefore, the use of a single-rod cylinder in the action cylinder 6 of this application will enable the device structure to be streamlined during use, and is conducive to use in narrow areas.

[0020] Secondly, the hanger device 8 is provided with a support rod 2 and a support rod sleeve 3. The support rod sleeve 3 is slidably connected to the support rod 2 and is sleeved on the outside of the support rod 2. The support rod sleeve 3 is arranged on the outside of the support rod 2 so that the support rod 2 can slide in the support rod sleeve 3. During operation, after connecting the air source and power supply, the support rod 2 in the hanger device 8 needs to be raised to the top of the inner hole in the support rod sleeve 3.

[0021] Then, the support rod 2 is provided with a plurality of cylindrical pins, which slide in conjunction with the claw body 1. The support rod 2 is provided with a plurality of cylindrical pins arranged in a line, which can be inserted into a plurality of U-shaped grooves of the claw body 1 to form a locking structure.

[0022] Furthermore, the outer surface of the support rod 2 and the inner sliding surface of the support rod sleeve 3 are both provided with a wear-resistant coating. Because the outer surface of the support rod 2 and the inner sliding surface of the support rod sleeve 3 are in sliding contact, by providing the wear-resistant coating on the outer surface of the support rod 2 and the inner sliding surface of the support rod sleeve 3, the service life of the support rod 2 and the support rod sleeve 3 can be increased, and the replacement time of the support rod 2 and the support rod sleeve 3 can be extended, which helps to reduce the cost of use.

[0023] Finally, the elastic member 5 is a coil spring. The elastic member 5 is a coil spring that can be directly mounted on the guide rod during installation. The elastic member 5 helps the actuating cylinder 6 quickly reach the locked position when the actuating cylinder 6 is actuated and locked, thereby providing quick locking assistance.

[0024] When using the utility model to realize quick locking of the fluidized bed bag shaking hanger, during operation, first connect the equipment air source and power supply, then control the action of the hanger device 8, raise the support rod 2 in the hanger device 8 to the top of the inner hole in the support rod sleeve 3, click the left and right cavity bag locking automatic control button on the display screen, the piston rod in the action cylinder 6 will extend, and after extending, push the cylinder fixing plate 4, and then with the help of the elastic member 5, that is, the elastic force of the coil spring, the multiple claws of the claw body 1 are clamped on the cylindrical pin on the support rod 2 in the support rod sleeve 3, completing the positioning and locking function, thereby realizing quick locking of the fluidized bed bag shaking hanger.

[0025] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
