[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] like Figure 1-Figure 4 As shown, the utility model provides a modulation device for the production of chemical reagent additives, including two legs 1, a mounting rod 3 and a support plate 5, the upper surface of the leg 1 is fixedly connected to a fixed frame 2, a plurality of modulation valves 4 are fixedly connected inside the mounting rod 3, a driving structure 6 is provided on the inner wall of the fixed frame 2, and an adjustment structure 7 is provided on the surface of the leg 1.

[0032] The specific settings and functions of the driving structure 6 and the regulating structure 7 are described in detail below.

[0033] like Figure 2As shown, the driving structure 6 includes a lead screw 601, which is rotatably connected to the fixed frame 2, a servo motor 602 is fixedly connected to the outer wall of the fixed frame 2, and the output end of the servo motor 602 is fixedly connected to the lead screw 601, and the arc surface of the lead screw 601 is threadedly connected with a slide tube 603, and the slide tube 603 is fixedly connected to the mounting rod 3. A limit rod 604 is fixedly connected to the inner wall of the fixed frame 2, and the limit rod 604 is slidably connected to the mounting rod 3. The movement of the slide tube 603 will drive the mounting rod 3 to slide along the arc surface of the limit rod 604, and the limit rod 604 can limit the moving path of the mounting rod 3, thereby limiting the moving path of the modulation valve 4, and the arc surface of the mounting rod 3 is fixedly connected to an electric push rod 605, and the output end of the electric push rod 605 is fixedly connected to a rack 6 06, the arc surface of the mounting rod 3 is rotatably connected to a rotating rod 607, the upper end of the rotating rod 607 is fixedly connected to a gear 608, the rack 606 is meshed with the gear 608, and the lower end of the rotating rod 607 is fixedly connected to a receiving box 609, which controls the output end of the electric push rod 605 to contract. At this time, the receiving box 609 will rotate to the bottom of the modulation valve 4, and the receiving box 609 can collect the auxiliary raw materials remaining in the modulation valve 4 to prevent the auxiliary raw materials from dripping onto the ground or other surfaces of objects during the movement of the modulation valve 4. The inner wall of the receiving box 609 is slidably connected to an adsorption pad 610, which can adsorb the auxiliary raw materials to prevent the auxiliary raw materials from spilling out of the receiving box 609 during the movement of the receiving box 609.

[0034] like Figure 3 and Figure 4 As shown, the adjustment structure 7 includes a sliding frame 71, which is slidably connected to the leg 1, and a card frame 72 is slidably connected inside the sliding frame 71. A serrated plate 73 is fixedly connected to the surface of the leg 1, and the card frame 72 is card-engaged with the serrated plate 73. The vertical section of the card frame 72 is a right-angled trapezoid. The sliding frame 71 is fixedly connected to the support plate 5, and a pull ring 74 is fixedly connected to the surface of the card frame 72. An elastic ring 75 is fixedly connected to the inner wall of the card frame 72, and the elastic ring 75 is fixedly connected to the sliding frame 71. When the elastic ring 75 contracts, the card frame 72 will re-engage with the serrated plate 73 with the help of the elastic force of the elastic ring 75. The surface of the pull ring 74 is fixedly covered with an anti-slip cover 76, and the anti-slip cover 76 serves to facilitate pulling the pull ring 74.

[0035] Its overall working principle is that when modulating chemical reagent additives, the raw materials of different types of chemical reagent additives are respectively connected to different modulation valves 4, and then the preparation tube is placed on the support plate 5, and then the output end of the electric push rod 605 is controlled to extend, and the output end of the electric push rod 605 will drive the rack 606 to move, and the rack 606 will drive the gear 608 to rotate, and the rotation of the gear 608 will drive the rotating rod 607 to rotate, and the rotation of the rotating rod 607 will cause the receiving box 609 to move away from the bottom of the modulation valve 4, and then the modulation valve 4 is opened, and the modulation valve 4 will discharge the raw materials of the chemical reagent additives into the preparation tube, thereby completing the purpose of modulating the chemical reagent additives. When it is necessary to discharge the raw materials of the chemical reagent additives into different preparation tubes, the output end of the electric push rod 605 is controlled to contract first, and at this time the receiving box 609 will rotate to the bottom of the modulation valve 4, and the receiving box 609 can move the raw materials of the chemical reagent additives from the modulation valve 4 is collected to prevent the auxiliary raw materials from dripping onto the ground or other surfaces of objects during the movement of the modulation valve 4. The adsorption pad 610 can adsorb the auxiliary raw materials to prevent the auxiliary raw materials from spilling out of the receiving box 609 during the movement of the receiving box 609. Then the servo motor 602 is turned on. The rotation of the output end of the servo motor 602 will drive the lead screw 601 to rotate. The rotation of the lead screw 601 will drive the slide tube 603 to move along the arc surface of the lead screw 601 with the help of the thread. The movement of the slide tube 603 will drive the installation rod 3 to slide along the arc surface of the limit rod 604. The limit rod 604 can limit the moving path of the installation rod 3, thereby limiting the moving path of the modulation valve 4. The movement of the installation rod 3 will drive the modulation valve 4 to move, thereby achieving the purpose of automatically moving the modulation valve 4. The operation is simple and convenient, and the working efficiency of the modulation device is improved.

[0036] When the height of the preparation cylinder is low and the distance between the preparation cylinder and the modulation valve 4 needs to be reduced, the sliding frame 71 is moved upward. The movement of the sliding frame 71 will drive the support plate 5 to move, thereby reducing the distance between the support plate 5 and the modulation valve 4 to avoid the splashing of the auxiliary agent raw material during the discharge process. At the same time, when the sliding frame 71 slides upward, the sliding frame 71 will also drive the clamping frame 72 to move. When the inclined surface of the clamping frame 72 slides along the inclined surface of the sawtooth plate 73, the sawtooth plate 73 will squeeze the clamping frame 72, and the clamping frame 72 will slide along the sliding frame 71 to stretch the elastic ring 75. When the inclined surface of the clamping frame 72 is out of contact with the inclined surface of the sawtooth plate 73, the elastic ring 75 begins to shrink, and the clamping frame 72 will re-engage with the sawtooth plate 73 with the help of the elastic force of the elastic ring 75. At this time, the plane of the lower surface of the clamping frame 72 will contact the sawtooth plate 73. The planar contact of the toothed plate 73 limits the position of the card frame 72, and further limits the height of the support plate 5. When the height of the preparation cylinder is high and the distance between the preparation cylinder and the modulation valve 4 needs to be increased, the pull ring 74 is pulled in the direction away from the support leg 1, and the anti-slip sleeve 76 facilitates the pulling of the pull ring 74. The movement of the pull ring 74 will drive the card frame 72 to move, so that the card frame 72 and the serrated plate 73 are out of contact. Thereafter, the pull ring 74 can be moved downward to lower the height of the support plate 5, making it convenient to place a high preparation cylinder on the support plate 5. Therefore, by adjusting the position of the support plate 5, an appropriate distance can be maintained between preparation cylinders of different sizes and the modulation valve 4, thereby avoiding the auxiliary agent raw materials discharged by the modulation valve 4 from splashing out of the preparation cylinder, thereby improving the practicability of the modulation device.

However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
