Technical Field

[0001] The utility model belongs to the technical field of pick-and-place machines, and specifically relates to an improved nozzle exchanger. Background Art

[0002] An improved nozzle exchanger is a device used for quickly and conveniently replacing nozzles. It is usually used in fields such as food processing, medical devices, and cosmetics. It can effectively improve production efficiency, reduce production costs, and improve product quality. Traditional nozzle replacement usually requires manual disassembly and installation, which is time-consuming and laborious and prone to misoperation, easily causing production line shutdowns and product quality problems. However, the improved nozzle exchanger can quickly replace the nozzle through simple operations, saving time and labor costs and improving production efficiency.

[0003] For example, a nozzle exchanger provided with a publication number of CN209949587U has a movable inner block and locking blocks on its side walls. The locking blocks can move, facilitating the simultaneous contact of the locking blocks with the nozzle when locking the nozzle, facilitating simultaneous force application, and avoiding the situation where individual force application is too large or too small when fixing nozzles of different sizes, which affects the installation stability.

[0004] When the above device is in use, the nozzle is fixed by the inner block and the locking blocks, preventing the fixing of the nozzle from being affected due to excessive or insufficient force when fixing different nozzles. However, the overall operation process of this device is relatively cumbersome and not convenient for the staff to quickly fix nozzles of different sizes. Summary of the Utility Model

The movable component includes a movable disk, a telescopic spring, a fixed block, and a movable column. The bottom surface of the movable column is fixedly connected to the top surface of the movable disk, and the bottom surface of the movable disk is fixedly connected to the top surface of the telescopic spring. The bottom surface of the telescopic spring is fixedly connected to the center of the top surface of the fixed block, and the movable column is located directly above the telescopic spring. A plurality of limiting blocks are fixedly installed on one side of the movable column.

[0007] Preferably, a circular hole adapted to the movable disk is formed at the center of the top surface of the exchanger body, and the outer surface of the movable disk is slidably connected to the inner wall of the circular hole. The bottom surface of the fixed block is fixedly connected to the inner bottom wall of the circular hole, and a stabilizing plate is installed above the circular hole.

[0008] Preferably, the bottom surface of the stabilizing plate is fixedly connected to the top surface of the exchanger body, and an A chute is formed on the top surface of the stabilizing plate. A sliding block is slidably installed inside the A chute.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 5 shown, the present utility model provides an improved nozzle exchanger, which includes an exchanger body 1. A movable component 2 is installed inside the exchanger body 1. A limiting component 3 is installed above the movable component 2 respectively. The movable component 2 includes a movable disk 21, a telescopic spring 22, a fixed block 23 and a movable column 24. The bottom surface of the movable column 24 is fixedly connected to the top surface of the movable disk 21, and the bottom surface of the movable disk 21 is fixedly connected to the top surface of the telescopic spring 22. The bottom surface of the telescopic spring 22 is fixedly connected to the center of the top surface of the fixed block 23, and the movable column 24 is located directly above the telescopic spring 22. A plurality of limiting blocks 241 are fixedly installed on one side of the movable column 24.

[0023] Adopting the above scheme: Through the setting of the movable disk 21, the movable column 24, the moving column 36 and the movable plate 33 can be driven to move synchronously by the movement of the movable disk 21, so that the movable plates 33 continuously approach each other and fix the position of the nozzle. Through the setting of the telescopic spring 22, the moved movable disk 21 can be restored to its original position.

[0024] As Figures 1 to 2As shown in the figure, a circular hole adapted to the movable disk 21 is provided at the center of the top surface of the exchanger body 1, and the outer surface of the movable disk 21 is slidably connected to the inner wall of the circular hole. The bottom surface of the fixed block 23 is fixedly connected to the inner bottom wall of the circular hole, and a stabilizing plate 11 is installed above the circular hole. The bottom surface of the stabilizing plate 11 is fixedly connected to the top surface of the exchanger body 1, and a chute A is provided on the top surface of the stabilizing plate 11. A sliding block 111 is slidably installed inside the chute A. The outer surface of the sliding block 111 is clamped to the inner wall of the limiting block 241, and the outer surface of the movable column 24 penetrates through the inner wall of the stabilizing plate 11.

[0025] Adopting the above solution: The distance that the sliding block 111 can move is provided through the inside of the chute A. When the sliding block 111 is pushed into the inside of the limiting block 241 by the setting of the sliding block 111, the positions of the movable column 24 and the movable disk 21 can be fixed, preventing the movable disk 21 from returning to its original state under the drive of the telescopic spring 22.

[0026] As Figures 3 to 5 shown in the figure, the limiting component 3 includes a limiting plate 31, a rotating column 32, a movable plate 33, a movable block 34, a rotating cylinder 35 and a moving column 36. The bottom surface of the limiting plate 31 is fixedly connected to the edge of the top surface of the exchanger body 1. The outer surface of the rotating column 32 penetrates through the inner wall of the movable plate 33 and is fixedly connected between the two. The two ends of the rotating column 32 are rotatably connected to the inner wall of the limiting plate 31. A buffer pad is fixedly installed on one side of the movable plate 33. A chute B is provided on the outer surface of the movable plate 33. The outer surface of the movable block 34 is slidably connected to the inner wall of the chute B. A circular hole adapted to the rotating cylinder 35 is provided in the inner wall of the movable block 34. The two ends of the rotating cylinder 35 penetrate through the inner wall of the circular hole and are rotatably connected between the two. The outer surface of the rotating cylinder 35 is fixedly connected to the inner wall of the moving column 36.

[0027] Adopting the above solution: Through the setting of the limiting plate 31, one end of the movable plate 33 can be restricted. Through the setting of the rotating column 32, the effect of the downward movement of the movable plate 33 is realized. Through the setting of the movable plate 33, when the movable plates 33 approach each other continuously, the position of the suction nozzle above the movable disk 21 can be fixed, preventing the suction nozzle from falling off. Through the setting of the movable block 34 and the rotating cylinder 35, when the moving column 36 moves downward, the movable plate 33 can be driven to move downward.

[0028] The working principle and usage process of the present utility model are as follows: First, the staff place suction nozzles of different shapes and sizes above the movable disk 21 and press the movable disk 21 downward. After the telescopic spring 22 receives the downward pressure, it will drive the entire movable disk 21 to move downward. At this time, the movable column 24 and the moving column 36 will move synchronously with the movable disk 21, causing the limiting block 241 to continuously enter the interior of the exchanger body 1. And at this time, the movable plate 33, driven by the movable block 34 and the rotating cylinder 35, also inclines towards the exchanger body 1.

[0029] Then, as the movable plates 33 continuously incline and approach each other, finally the buffer pads come into contact with the outer surface of the suction nozzle, and continue to apply downward pressure to the movable disk 21, enabling the movable plate 33 to fix the position of the suction nozzle by means of the downward pressure, and pushing the sliding block 111 into the interior of the limiting block 241. The movable disk 21 is fixed at the position of the movable plate 33 through the mutual cooperation between the sliding block 111 and the limiting block 241. Thus, the entire operation process ends.
