[0034] Reference Figure 2 , Figure 5 and Figure 6 The top of the bottom plate 1 is provided with an adjusting device 6, which includes a motor 61. The bottom end of the motor 61 is fixedly connected to the top of the bottom plate 1. A threaded rod 62 is provided above the output shaft of the motor 61. The motor 61 and the threaded rod 62 are connected through a protective component 63. The protective component 63 includes a fixing ring 631. The fixing ring 631 is in the shape of a cylinder with a groove on the top. The bottom end of the fixing ring 631 is fixedly connected to the top of the output shaft of the motor 61. The inner wall of the fixing ring 631 is provided with a sliding groove 632. The inner wall is slidably connected with a block 633, the size of which matches the sliding groove 632, and the end of the block 633 away from the threaded rod 62 is elastically connected to the inner wall of the sliding groove 632 through a spring 2 634, one end of the spring 2 634 is fixedly connected to the end of the block 633 away from the threaded rod 62, and the other end of the spring 2 634 is fixedly connected to the inner wall of the sliding groove 632, and the shape of the block 633 is a shape formed by the combination of a cylinder and a hemisphere, and the hemisphere of the block 633 is arranged at the end away from the spring 2 634.

[0035] Reference Figure 2 - Figure 4The outer wall of the threaded rod 62 is provided with a limiting hole 635, the outer wall of the threaded rod 62 passes through and is threadedly connected with a moving block 64, the top of the bottom plate 1 is fixedly connected with a sliding rod 66, the moving block 64 passes through and is slidably connected with the outer wall of the sliding rod 66, and the setting of the sliding rod 66 ensures that when the threaded rod 62 rotates, the moving block 64 can only move up and down, and will not rotate with the rotation of the threaded rod 62, the right end of the moving block 64 is fixedly connected to the left end of the filling head body 5, and the bottom of the moving block 64 is provided with a clamping assembly 65, and the clamping assembly 65 includes a pressing plate 651, and the pressing plate 65 1 is fixedly connected to the front end of the moving block 64, the pressing plate 651 penetrates and is fixedly connected to the front end outer wall of the filling head body 5, the inside of the pressing plate 651 penetrates and is fixedly connected with an air pressure tube 652, the front end inner wall piston of the air pressure tube 652 is connected with a slider 653, the outer wall of the slider 653 fits with the inner wall of the air pressure tube 652, the top of the slider 653 is elastically connected to the inner wall of the air pressure tube 652 through a spring 654, one end of the spring 654 is fixedly connected to the top of the slider 653, and the other end of the spring 654 is fixedly connected to the inner wall of the air pressure tube 652.

[0036] Reference Figure 2 - Figure 4 The outer wall of the air pressure tube 652 passes through and is fixedly connected to the inner wall of the moving block 64. The end of the air pressure tube 652 away from the slider 653 is fixedly connected to an air bag 655. The interior of the air bag 655 is connected to the interior of the air pressure tube 652. The shape of the air bag 655 is annular. The shape setting of the air bag 655 ensures that the air bag 655 can better fit the outer wall of the threaded rod 62, and the air bag 655 passes through the middle inner wall of the moving block 64. The lower end of the slider 653 is fixedly connected to a contact block 656. The shape of the contact block 656 is a rectangular parallelepiped with a cylinder cut in the middle. The front end of the filling head body 5 is set in the middle of the contact block 656. The positional relationship between the filling head body 5 and the contact block 656 ensures that the edge of the container can contact the contact block 656.

[0037] Working principle: When in use, the staff first starts the equipment, so that the container to be filled moves under the drive of the conveyor belt 2. When the container moves to the bottom of the filling head body 5 under the drive of the conveyor belt 2, the staff starts the motor 61, so that the motor 61 drives the threaded rod 62 to rotate through the protective component 63, so that the moving block 64 moves downward again under the drive of the threaded rod 62.

[0038] When the moving block 64 moves downward until it can no longer move, when the motor 61 drives the fixing ring 631 to rotate, since the threaded rod 62 cannot rotate with the fixing ring 631, the edge of the blocking block 633 enters the sliding groove 632 after being subjected to force, so that the fixing ring 631 can rotate relative to the threaded rod 62, so that the container will not be damaged under the action of the downward pressure.

[0039] During the downward movement of the moving block 64, the contact block 656 first contacts the upper end of the container. After the contact block 656 contacts the upper end of the container, since the moving block 64 continues to move downward, the contact block 656 moves upward relative to the moving block 64. Therefore, the contact block 656 pushes the slider 653 upward, increasing the pressure inside the air pressure tube 652, thereby expanding the airbag 655, so that the inner wall of the moving block 64 fits the outer wall of the threaded rod 62, while preventing the threaded rod 62 from wearing out due to excessive force caused by the collision between the inner wall of the moving block 64 and the rotating force, thereby affecting the service life.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
