Technical Field

[0001] This utility model relates to the technical field of chemical raw material conveying equipment, and in particular to a quantitative conveying device for chemical raw materials. Background Technology

[0002] In chemical production, raw material transportation is a crucial step. Traditional methods of transporting chemical raw materials often suffer from inaccurate delivery rates, poor stability, and susceptibility to damage, severely impacting production efficiency and product quality. To address these issues, various chemical raw material transportation devices have emerged on the market; however, these devices still have some shortcomings in design and functionality.

[0003] First, traditional chemical raw material conveying devices are often not precise enough in controlling the conveying volume, leading to waste or insufficient raw materials and affecting subsequent production processes. Second, these devices have poor operational stability and are prone to shaking or deviation, affecting the accuracy and safety of conveying. In addition, some devices are prone to damage or failure during long-term use due to the large pressure and deformation they withstand, increasing the cost of maintenance and replacement parts. Therefore, we provide a quantitative conveying device for chemical raw materials. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a quantitative conveying device for chemical raw materials, which more accurately solves the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] The utility model proposes a quantitative conveying device for chemical raw materials, including a side frame, and a conveying structure connected between two side frames; a support rod and a side strip are fixedly installed on the side of the side frame respectively, and a quantitative conveying component is connected between the support rod and the side strip;

[0007] The quantitative conveying assembly includes an overlapping rod fixedly installed between two support rods and an overlapping plate fixedly installed on the lower surface of two side support frames. An opening / closing button one is fixedly installed on the lower surface of the overlapping plate, and an opening / closing button two is fixedly installed on the upper surface of the overlapping rod. A bearing plate is installed between the two side support bars, and a connecting plate is fixedly connected to one side of the bearing plate. An upper touch rod and a lower touch rod are fixedly connected to the upper and lower surfaces of the connecting plate, respectively. A reset component is connected between the side support bars and the bearing plate.

[0008] Furthermore, the reset component includes a strip-shaped through groove formed on the surface of the side retaining strip, a retaining rod is fixedly connected between the two end walls of the strip-shaped through groove, a spring is sleeved around the retaining rod, and a sliding sleeve block is slidably sleeved around the retaining rod.

[0009] Furthermore, the conveying structure includes a rotating cylinder rotatably connected between two side-fixed frames via a shaft, a feeding belt is wound around the periphery of the two rotating cylinders, a drive motor is fixedly installed on the side of one of the side-fixed frames, and the output end of the drive motor is fixedly connected to the end of a shaft.

[0010] Furthermore, the sliding sleeve is slidably connected to the inner wall of the strip groove, and the opposite surfaces of the two sliding sleeves are fixedly connected to the front and back surfaces of the bearing plate, respectively.

[0011] Furthermore, the upper touch lever is designed to be directly below the first open / close button, and the lower touch lever is designed to be directly above the second open / close button. Both the first open / close button and the second open / close button are electrically connected to the drive motor via wires.

[0012] Furthermore, the upper end of the spring is fixedly connected to the lower end surface of the sliding sleeve block, and the lower end of the spring is fixedly connected to the end wall of the strip-shaped through groove.

[0013] The beneficial effects of this utility model are:

[0014] This invention, through its designed quantitative conveying component and reset component, enables precise control of the amount of raw material conveyed each time. When the support plate carries a certain amount of chemical raw material and moves to the designated position, the touch lever triggers the start / stop button, thereby controlling the start and stop of the drive motor to achieve quantitative conveying of the raw material. At the same time, the spring in the reset component provides a reset force after the support plate moves, causing the support plate to automatically return to its initial position, preparing for the next conveying. This design not only improves production efficiency but also ensures the accuracy and stability of raw material conveying.

[0015] This invention employs a robust side-fixing frame, support rod, and side-fixing strip structure, along with a sliding connection between the sliding sleeve block and the strip-shaped through groove, ensuring the stability of the entire device during operation. Furthermore, the coordinated design of the spring and the upright rod allows the reset component to withstand significant pressure and deformation without damage or failure. This design not only improves the durability of the device but also reduces the cost of maintenance and component replacement. Attached Figure Description

[0020] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0021] Example

[0022] like Figures 1-3 As shown, an embodiment of this utility model discloses a quantitative conveying device for chemical raw materials, mainly composed of side-fixing frames 1. Two side-fixing frames 1 are arranged in parallel and connected by a conveying structure to realize the conveying of raw materials. Support rods 2 and side-fixing strips 3 are fixedly installed on the sides of the side-fixing frames 1, and these two parts of the structure jointly support and stabilize the entire device. A quantitative conveying assembly is installed between the support rods 2 and the side-fixing strips 3. This assembly includes an overlapping rod 4 between the two support rods 2 and an overlapping plate 5 on the lower surface of the two side-fixing frames 1. An on / off button 6 is provided on the lower surface of the overlapping plate 5 for controlling a certain function; while an on / off button 7 is provided on the upper surface of the overlapping rod 4, also for control. A bearing plate 8 is installed between the two side-fixing strips 3 for carrying chemical raw materials. One side of the bearing plate 8 is connected to an upper touch rod 10 and a lower touch rod 11 through a connecting plate 9. Under specific conditions, these two touch rods will contact the on / off button 6 and the on / off button 7 respectively, thereby triggering the corresponding control action. In addition, a reset component is connected between the side fixing strip 3 and the carrier plate 8 to return the carrier plate 8 to its initial position after the conveying is completed.

[0023] Furthermore, the reset component is specifically implemented by creating a strip-shaped through groove 12 on the surface of the side retaining strip 3. A vertical retaining rod 13 is installed within the strip-shaped through groove 12, and a spring 14 is sleeved around the vertical retaining rod 13 to provide a reset force. A sliding sleeve block 15 is also slidably connected to the vertical retaining rod 13. The sliding sleeve block 15 slides within the strip-shaped through groove 12, and the opposing surfaces of the two sliding sleeve blocks 15 are fixedly connected to the front and back surfaces of the support plate 8, respectively. Thus, when the support plate 8 moves up and down, it causes the sliding sleeve block 15 to slide on the vertical retaining rod 13, and the spring 14 deforms. When the external force disappears, the reset force of the spring 14 causes the support plate 8 to return to its initial position. The design of the reset component ensures that the support plate 8 can automatically and smoothly return to its initial position after conveying the raw material, preparing for the next conveying operation.

[0024] Furthermore, the conveying structure consists of two rotating drums 16 and a feeding belt 17. The rotating drums 16 are rotatably connected between two side-mounted frames 1 via a shaft, and the feeding belt 17 is wound around the outer perimeter of the rotating drums 16 for conveying chemical raw materials. A drive motor 18 is fixedly installed on the side of one of the side-mounted frames 1, and the output end of the drive motor 18 is fixedly connected to the end of a shaft. The rotation of the drive motor 18 drives the rotation of the rotating drums 16 and the feeding belt 17.

[0025] Furthermore, the sliding sleeve 15 is slidably connected to the inner wall of the strip groove 12, ensuring the stability and accuracy of the support plate 8 during vertical movement. Simultaneously, the opposing surfaces of the two sliding sleeves 15 are fixedly connected to the front and back surfaces of the support plate 8, respectively. Thus, the vertical movement of the support plate 8 directly drives the sliding sleeves 15 to slide within the strip groove 12. The sliding connection between the sliding sleeves 15 and the strip groove 12, as well as their fixed connection to the support plate 8, together ensure the reliability and stability of the reset component.

[0026] Furthermore, the upper touch lever 10 is positioned directly below the first on / off button 6, and the lower touch lever 11 is positioned directly above the second on / off button 7. When the support plate 8 moves upward to a certain position, the upper touch lever 10 will press the first on / off button 6; when the support plate 8 moves downward to a certain position, the lower touch lever 11 will press the second on / off button 7. Both the first on / off button 6 and the second on / off button 7 are electrically connected to the drive motor 18 via wires, and are used to control the start and stop of the drive motor 18.

[0027] Furthermore, the upper end of the spring 14 is fixedly connected to the lower end surface of the sliding sleeve 15, and the lower end is fixedly connected to the end wall of the strip groove 12. Thus, when the support plate 8 moves up and down, the spring 14 deforms, generating a restoring force. When the external force disappears, the restoring force of the spring 14 will return the support plate 8 and the sliding sleeve 15 to their initial positions. The fixed connection of the spring 14 ensures the reliability and stability of the restoring component, providing a strong guarantee for the automatic restoring of the support plate 8.
