Most of the materials processed in chemical production are fluids. Transporting these materials between various chemical equipment and machines according to process requirements is an important link in realizing chemical production.

[0003] Commonly used conveying equipment generally controls the liquid delivery volume by timing the opening and closing of valves. However, in the actual production process, the liquid circulation speed varies depending on the viscosity and density of the actual conveyed liquid and the pressure inside the tank. Therefore, the conveying equipment cannot ensure the consistency of the single delivery volume and the use effect is poor. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Combination Figure 1-6 As shown, an automatic conveying and metering device comprises:

[0026] The base 1 is a cylindrical structure, and a conveying disc 11 is arranged on the top surface, and the two are movably connected by a bearing structure, and an electric motor is embedded inside the top surface of the base 1, and the top end of the electric motor is fixedly connected to the center of the bottom surface of the conveying disc 11, so as to drive the conveying disc 11 to perform directional circular motion;

[0027] There are multiple mounting grooves 2, which are arranged around the edge of the conveying plate 11;

[0028] There are multiple weighing racks 3, which are embedded in the mounting groove 2 one by one. A bottle for holding liquid is placed in the center, and a guide pipe 34 for auxiliary transportation is provided on the top.

[0029] The lifting cylinder 4 is arranged on one side of the base 1 and is aligned with the bottom of one of the mounting grooves 2;

[0030] The material storage tank 5 is a tank body for holding liquid, and is exactly located on the top of one of the mounting grooves 2 and aligned therewith. The lifting cylinder 4, the material storage tank 5 and the mounting groove 2 are spaced apart and concentrically arranged.

[0031] Specifically, the mounting groove 2 is configured as a circular groove, and a circular through hole 22 is provided at the center of its bottom surface. The top end of the lifting cylinder 4 is aligned with the circular through hole 22, and a partition is provided at the top end of the lifting cylinder 4. The partition is also configured as a circle and is slightly smaller than the circular through hole 22, and a layer of elastic pad is also provided on the top surface of the partition.

[0032] The weighing frame 3 includes a circular base plate 31, a connecting ring 32 and a tripod 33, wherein the circular base plate 31 is located at the bottom and is completely embedded in the mounting groove 2. After being installed inside, the top surface of the circular base plate 31 is flush with the top surface of the conveying disc 11. Three supporting columns are vertically arranged on the top surface of the circular base plate 31. The connecting ring 32 is fixedly connected to the top ends of the three supporting columns. The tripod 33 is fixedly installed on the top of the connecting ring 32, and the center of the tripod 33 is aligned with the center of the circular base plate 31 up and down, and a circular mounting hole is provided inside it. The guide tube 34 is vertically installed inside the mounting hole so that its top and bottom ends are respectively located at the top and bottom of the tripod 33.

[0033] Since the three support columns are arranged in a circular array, the distances between the three support columns are relatively large, which can ensure that the bottle can be freely taken and placed.

[0034] A limiting groove 21 is vertically arranged inside the mounting groove 2, and a protrusion is correspondingly arranged on the side wall of the circular bottom plate 31 and is slidably inserted into the limiting groove 21. The two are slidably inserted so that the weighing frame 3 and the conveying plate 11 are connected as a whole.

[0035] At the same time, the circular bottom plate 31 fits the bottom surface of the mounting groove 2, so its bottom surface just covers the circular through hole 22 on the mounting groove 2, and the partition on the lifting cylinder 4 is just located inside the circular through hole 22 and its top surface fits with the center of the bottom surface of the circular bottom plate 31.

[0036] A plurality of slide grooves 52 are provided on the inner wall of the discharge port 51 of the storage tank 5, and a fixing ring 54 is provided at the center. A return spring 53 is provided inside each slide groove 52, and one end of the return spring 53 is fixedly connected to the end face of the slide groove 52, and the other end of the return spring 53 is fixedly connected to the side wall of the fixing ring 54. A conical sealing block 55 is also provided at the center of the fixing ring 54. In a natural state, the return spring 53 pulls the conical sealing block 55 downward so that its side wall fits with the inner wall of the discharge port 51 to form a seal.

[0037] In addition, a top core 35 is vertically arranged at the center of the guide tube 34, and the side wall of the top core 35 is fixedly connected to the inner wall of the guide tube 34 through a bracket. Therefore, when the top core 35 moves upward, it pushes the conical sealing block 55 upward for transportation. When the top core 35 moves downward, the conical sealing block 55 is affected by the return spring 53 and automatically completes the sealing. The lifting cylinder 4 serves as its power source and controls the on and off through the lifting and lowering adjustment in conjunction with the guide tube 34. During the lifting process, the circular bottom plate 31 should still retain at least half of its thickness inside the mounting groove 2 to prevent it from tipping over or shifting due to external vibration.

[0038] A gravity sensor 36 is also provided at the center of the top surface of the circular bottom plate 31. The gravity sensor 36 can be one of the AP-C30, AP-V80 and other series, and its detection surface is ensured to be consistent in height with the top surface of its circular bottom surface.

[0039] A control box 12 is also provided at the center of the top surface of the conveying plate 11. The control box 12 is internally provided with an intelligent control system having a comparison circuit, a PLC single-chip computer and a remote control module. The control box 12 is electrically connected to all gravity sensors 36 through wires. The purpose is to monitor the amount of liquid injected into the bottle body through the internal comparison circuit. When the amount of liquid reaches the specified standard, the PLC single-chip computer inside the control box 12 automatically controls the lifting cylinder 4 through remote control, forcing it to descend and disconnecting the guide pipe 34 from the discharge port 51. In the above process, the entire operation is fully automated, without the need for manual auxiliary operation, and the gravity detection method is used to detect the amount of liquid injected at a single time. Compared with the existing injection method, it is more accurate and will not be affected by the viscosity and density of the liquid and the pressure inside the tank body, thereby maintaining the consistency of the packaging production.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
