Description

Technical Field

[0001] This utility model relates to the technical field of building gypsum raw materials, specifically an automatic metering and feeding device for building gypsum raw materials. Background Technology

[0002] The raw materials for building gypsum can be natural gypsum or industrial by-product gypsum, such as phosphogypsum and desulfurized gypsum. When selecting raw materials, factors such as purity, chemical composition, and physical properties need to be considered. When feeding building gypsum raw materials, an automatic metering and feeding device is required for auxiliary processing.

[0003] Existing automatic metering and feeding devices have certain drawbacks. They typically rely on manual feeding, resulting in high labor intensity and low efficiency. While some feeding devices exist, they cannot accurately measure weight. To overcome these shortcomings, an automatic metering and feeding device for rust-preventive powder production can be referenced (Chinese Patent Application No. CN201921954885.3, published on 2020-06-23). ​​This device effectively prevents dust from flying during the feeding process by using a dust baffle. By using discharge pipes made in specific proportions and working in conjunction with a vibrating motor, it controls the different raw materials to fall into the mixing tank at a specific ratio and speed. A metering device and a remote signal controller accurately measure the mass of materials in the mixing tank. A stirring device ensures thorough mixing of the materials. An arc-shaped pusher plate, a guide pipe, and a spiral feeding device transport the materials.

[0004] However, other defects still exist during use. When conveying powdered raw materials, some powder will remain inside the feed pipe and cannot be cleaned in time. Manual cleaning is required, which is cumbersome.

[0005] Therefore, we proposed that an automatic metering and feeding device for building gypsum raw materials can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic metering and feeding device for building gypsum raw materials, so as to solve the problem mentioned in the background art that when the automatic metering and feeding devices on the market transport powdered raw materials, some powder will remain inside the feeding pipe and cannot be cleaned in time, requiring manual cleaning, which is cumbersome to operate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic metering and feeding device for building gypsum raw materials, comprising a feeding pipe fixedly installed on the ground, the top of the feeding pipe being connected to a feeding assembly via a flange connection plate; a feeding port being provided at the bottom of the feeding pipe, a control panel being installed on the side of the feeding pipe, a servo motor being installed on one side of the top of the feeding pipe, the output end of the servo motor being connected to the shaft end of the feeding disc; a drive motor being installed below the control panel on the feeding pipe, the output end of the drive motor being connected to a metering mechanism, and the metering result being displayed on the control panel; when the metering mechanism rotates, it can drive a striking mechanism to operate, the striking mechanism can vibrate and feed the powdery material remaining inside the feeding pipe.

[0008] As a preferred technical solution of this application, the measuring mechanism includes a rotating cylinder fixedly connected to the output end of the drive motor. The rotating cylinder has four sets of grooves about the center of the rotating cylinder, and a collection frame is placed inside the groove. The bottom corners of the collection frame are connected to the inner wall of the groove through guides. The bottom of the collection frame is also connected to the top of the weighing platform.

[0009] As a preferred technical solution of this application, the guide component is provided with a rubber elastic column inside, and the weighing platform is located below the feeding tray.

[0010] As a preferred technical solution of this application, the feed pipe body is provided with a ramp at the middle position between the weighing platform and the unloading tray, and the size of the through groove opened below the ramp is smaller than the size of the collection frame.

[0011] As a preferred technical solution of this application, the striking mechanism includes a fixed plate fixed to one side of the feed tube body. The fixed plate is located at the end of the rotating cylinder away from the slope. Several sets of protrusions are fixed at equal angles on the inner side of the fixed plate. The end of the rotating cylinder is rotatably disposed inside the feed tube body. A crossbar is also fixed at the outer end of the rotating cylinder outside the feed tube body. The end of the crossbar is rotatably connected to the striking block. The rotatable connection between the crossbar and the striking block is connected by a torsion spring.

[0012] As a preferred technical solution of this application, the outer side of the striking block is between the two sets of protrusions, and the striking block forms a rotating structure between the protrusions and the crossbar.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic metering and feeding device for building gypsum raw materials is equipped with a metering mechanism, which can weigh the material inside the collection box, and through the set knocking mechanism, it can discharge the building gypsum raw materials remaining inside the feeding pipe. The specific details are as follows:

[0014] 1. A rotating drum is installed, through which materials are collected and processed by a collection frame inside the rotating drum, and the materials inside the collection frame are weighed by a weighing platform. Furthermore, the dustproof effect can be achieved by closing the set feeding tray.

[0015] 2. A fixed plate is set up. Since the fixed plate has several protrusions inside, when the rotating cylinder rotates, it can drive the crossbar and the striking block to rotate. This allows the striking block to move inside the two sets of protrusions. Through the setting of the torsion spring, a striking phenomenon can occur, thereby achieving the purpose of vibration cleaning and unloading. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: Example

[0025] The system includes a feed pipe 1 fixedly installed on the ground, with its top connected to a feeding assembly via a flange connection plate 2; a feeding port 3 is located at the bottom of the feed pipe 1; a control panel 4 is installed on the side of the feed pipe 1; a servo motor 5 is installed on one side of the top of the feed pipe 1, with its output end connected to the shaft end of the feeding disc 6; a drive motor 8 is installed below the control panel 4 on the feed pipe 1, with its output end connected to a metering mechanism, and the measurement result of the metering mechanism is displayed on the control panel 4; the metering mechanism includes a drive motor... The rotating cylinder 9 is fixedly connected to the output end of the machine 8. The rotating cylinder 9 has four sets of grooves about its center. The collection frame 10 is placed inside the grooves. The bottom corners of the collection frame 10 are connected to the inner wall of the groove through the guide 12. The bottom of the collection frame 10 is also connected to the top of the weighing platform 11. The guide 12 has a rubber elastic column inside. The weighing platform 11 is located below the feeding tray 6. The feed pipe 1 is located in the middle of the weighing platform 11 and the feeding tray 6 and has a ramp 7. The through groove below the ramp 7 is smaller than the size of the collection frame 10.

[0026] When metering the raw building gypsum material, the flange connecting plate 2 is first closed to the feeding assembly. The servo motor 5 is rotated by the control panel 4, which drives the feeding plate 6 to rotate. The feeding plate 6 rotates inside the upper end of the feeding pipe 1. Before rotation, the drive motor 8 drives the rotating cylinder 9 to rotate, so that a set of collection frames 10 of the rotating cylinder 9 is directly below the through groove of the slope 7. When the feeding plate 6 is opened, the raw building gypsum material will fall into the collection frame 10. After the appropriate amount is added, the feeding plate 6 is closed. At this time, the feeding plate 6 can also achieve the effect of dust prevention. After the raw building gypsum material falls into the collection frame 10, the collection frame 10 will move by the guide 12. At this time, the raw building gypsum material will be weighed by the weighing platform 11, and the weighed data will be displayed on the control panel 4. Example

[0027] When the metering mechanism rotates, it can drive the striking mechanism to operate. The striking mechanism can vibrate and discharge the powdery material remaining inside the feed tube 1. The striking mechanism includes a fixed plate 13 fixed to one side of the feed tube 1. The fixed plate 13 is located at the end of the rotating cylinder 9 away from the slope 7. Several sets of protrusions 131 are fixed at equal angles on the inner side of the fixed plate 13. The end of the rotating cylinder 9 is rotatably set inside the feed tube 1. A crossbar 91 is also fixed at the outer end of the rotating cylinder 9. The end of the crossbar 91 is rotatably connected to the striking block 93. The rotatable connection between the crossbar 91 and the striking block 93 is connected by a torsion spring 92. The outer side of the striking block 93 is between the two sets of protrusions 131, and the striking block 93 forms a rotating structure between the protrusions 131 and the crossbar 91.

[0028] When metering continues, the drive motor 8 can drive the rotating cylinder 9 to rotate inside the feed tube 1. First, during the rotation of the rotating cylinder 9, the crossbar 91 can rotate on the outside of the feed tube 1. When the crossbar 91 rotates, it can drive the striking block 93 to slide within the two adjacent sets of protrusions 131. At this time, one end of the striking block 93 will be blocked by the protrusion 131 and thus rotate. When the protrusion 131 is no longer blocked, the striking block 93 will be reset and rotated by the torsion spring 92, so that one end of the striking block 93 strikes one side of the protrusion 131, thereby causing the feed tube 1 to vibrate. At this time, the residual building gypsum material on the surface of the ramp 7 opened inside the feed tube 1 can fall down, thus avoiding manual cleaning.

[0029] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
