DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0021] Referring to Figures 1-3 An energy-saving high-vacuum vacuum generator, comprising a vacuum generator shell 1, two connecting rings 2 and an adsorption head 4, the two connecting rings 2 are fixedly connected at both ends of the vacuum generator shell 1 respectively, the adsorption head 4 is fixedly connected on the side wall of the vacuum generator shell 1, a through hole is formed on the side wall of the adsorption head 4, a fixed ring 6 is fixedly connected on the inner wall of the vacuum generator shell 1, a rectangular opening is formed on the inner wall of the fixed ring 6, a fixed rod 7 is fixedly connected on the inner wall of the rectangular opening of the fixed ring 6, a guide plate 8 is movably sleeved on the rod wall of the fixed rod 7, an electric push rod 10 is fixedly connected on the inner wall of the vacuum generator shell 1, a sliding block 11 is fixedly connected on the piston rod end of the electric push rod 10, a transmission rod 12 is hingedly arranged on the side wall of the sliding block 11, one end of the transmission rod 12 away from the sliding block 11 is hingedly arranged on the side wall of the guide plate 8, a detection opening is formed on the side wall of the adsorption head 4, and a detection cylinder 14 is fixedly connected on the side wall of the adsorption head 4 at the detection opening.
[0022] A plurality of mounting bolts 3 are threadedly connected on the inner walls of the two connecting rings 2 respectively, a sealing rubber ring 5 is fixedly connected on the end of the adsorption head 4 away from the vacuum generator shell 1, a sealing rubber pad 9 is fixedly connected on the inner wall of the rectangular opening of the fixed ring 6, the sealing rubber pad 9 is arranged in close contact with the guide plate 8, a stabilizing block 13 is fixedly connected on the side wall of the sliding block 11, a rectangular groove is formed on the inner wall of the vacuum generator shell 1, and the stabilizing block 13 is slidingly arranged on the inner wall of the rectangular groove.
[0023] The connecting ring 2 at both ends of the vacuum generator shell 1 is connected with the external gas source pipeline through the mounting bolt 3. When the gas source is connected, the gas enters the shell from one end of the connecting ring 2 and then flows out from the other end of the connecting ring 2. The adsorption head 4 away from one end of the shell is tightly attached to the surface of the adsorbed object through the sealing rubber ring 5 to form a sealed space. When the airflow speed in the vacuum generator shell 1 increases, the negative pressure partial vacuum is generated at the through hole of the adsorption head 4 to adsorb and fix the object. The sealing rubber pad 9 between the fixing ring 6 and the flow guide plate 8 can prevent gas leakage and ensure the stability of the vacuum degree. The rectangular port in the inner wall of the fixing ring 6 is provided with the flow guide plate 8. The flow guide plate 8 is hinged on the fixing ring 6 through the fixing rod 7 and is attached to the sealing rubber pad 9 to ensure the sealing property.
[0024] When the electric push rod 10 is started, the piston rod pushes the sliding block 11 to slide in the rectangular groove. The sliding block 11 drives the flow guide plate 8 to rotate around the fixing rod 7 through the transmission rod 12, so as to change the included angle between the flow guide plate 8 and the airflow direction. When the included angle of the flow guide plate 8 increases, the sectional area of the airflow passing through the rectangular port decreases, the flow speed increases, and according to the Bernoulli principle, the vacuum degree at the adsorption head 4 increases. Conversely, reducing the included angle of the flow guide plate 8 can reduce the vacuum degree to realize the precise adjustment of the vacuum degree. The stability block 13 on the side wall of the sliding block 11 is in sliding fit with the rectangular groove in the inner wall of the shell to prevent the sliding block 11 from deviating during the movement and to ensure the stability of the transmission rod 12 pushing the flow guide plate 8. The angle of the flow guide plate 8 is precisely controlled through the electric push rod 10 to avoid the energy loss of the traditional mechanical adjustment. At the same time, the vacuum degree is dynamically adjusted according to the actual demand to realize the energy saving effect.
[0025] In order to realize the dynamic monitoring of the vacuum degree, as shown in Figures 1-3 The inner wall of the detection cylinder 14 is slidably provided with the sealing piston 15.

The side wall of the sealing piston 15 is fixedly connected with the scale 17. The end of the detection cylinder 14 is provided with a through hole. The scale 17 is slidably arranged on the inner wall of the through hole. The end of the detection cylinder 14 away from the adsorption head 4 is fixedly connected with the pointer 18. The pointer 18 is slidably arranged on the side wall of the scale 17.
[0026] The detection cylinder 14 is in communication with the inside of the adsorption head 4 through the detection port. When the adsorption head 4 generates vacuum, the sealing piston 15 in the detection cylinder 14 slides to the left under the action of the internal and external pressure difference. The tension spring 16 is elongated and drives the scale 17 to move to the left. The scale on the scale 17 cooperates with the pointer 18 to directly display the current vacuum degree value. When the vacuum degree decreases, the tension spring 16 resets and pushes the sealing piston 15 to move to the right. The scale 17 is synchronously reset to realize the dynamic monitoring of the vacuum degree.
[0027] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
