Description

Technical Field

[0001] This utility model relates to the field of refractory material processing and production technology, and in particular to an automatic feeding cart receiving port lifting and docking device. Background Technology

[0002] In the refractory material processing and production field, with the continuous advancement of industrial automation, many tasks can be completed through computer control in an automated control room, greatly reducing manual labor intensity and significantly improving production efficiency. In the refractory material sector, automated batching, automated feeding, and automated pressing of finished products have been widely promoted and applied. Existing automated feeding systems involve a feeding trolley that automatically travels along a track below the mixer's hopper. When the trolley automatically moves to the bottom of the mixer's hopper, the top receiving port of its weighing hopper aligns precisely with the discharge port of the mixer's hopper, achieving accurate receiving and feeding. However, due to the gap between the receiving port of the hopper and the discharge port of the mixer's hopper, powder leakage is easily caused during the receiving process, leading to powder spillage, environmental pollution, and even dust explosions. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an automatic feeding cart receiving port lifting and docking device.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution: The automatic feeding trolley receiving port lifting and docking device of this utility model includes a scissor-type lifting frame installed on the receiving port at the top of the automatic feeding trolley receiving hopper. The upper end of the scissor-type lifting frame has a horizontally installed lifting plate, and the lower end has a fixed plate fixedly connected to the automatic feeding trolley receiving hopper. A docking interface for docking with the discharge port of the mixing machine hopper is opened on the lifting plate. A flexible dustproof sleeve located inside the scissor-type lifting frame is connected to the lower edge of the docking interface. The lower end of the flexible dustproof sleeve is connected to the receiving port of the automatic feeding trolley receiving hopper, forming a sealed dustproof channel connecting the docking interface and the automatic feeding trolley receiving hopper.

[0005] Furthermore, the scissor lift is a pneumatic lift, with a pair of vertically upward cylinders symmetrically arranged between its lifting plate and fixed plate. The extension and retraction ends of the two cylinders extend and retract synchronously, thereby driving the lifting plate to rise or fall smoothly.

[0006] Furthermore, the upper edge of the interface is connected to a horn-shaped auxiliary alignment port that is larger at the top and smaller at the bottom. The horn-shaped auxiliary alignment port is coaxially arranged with the interface, which ensures that the interface and the discharge port of the mixing machine can be connected even if there is a slight deviation, thus improving the compatibility of the interface.

[0007] The advantages of this utility model lie in the fact that by using a scissor-type lifting frame installed on the top receiving port of the automatic feeding trolley's receiving hopper, and a docking interface on the upper lifting plate of the scissor-type lifting frame, it can easily achieve accurate docking with the discharge port of the mixing machine's hopper. Furthermore, by using a flexible dustproof sleeve connecting the docking interface and the automatic feeding trolley's receiving hopper, the movement gap between the automatic feeding trolley's receiving hopper and the mixing machine's hopper discharge port is overcome, improving the sealing performance of the docking between the automatic feeding trolley's receiving hopper and the mixing machine's hopper discharge port. This minimizes the leakage of powder and material during the receiving process, preventing powder from scattering and polluting the environment. It has strong adaptability and practicality, and the entire lifting and docking device is durable and has low maintenance costs, providing a reliable guarantee for the automated batching and feeding process of refractory material processing and production.

[0010] 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.

[0011] like Figure 1 , 2 As shown, the automatic feeding vehicle receiving port lifting and docking device of this utility model includes a scissor-type lifting frame 1 installed on the receiving port at the top of the automatic feeding vehicle receiving hopper 100. The scissor-type lifting frame 1 is a pneumatic lifting frame. Specifically, the upper end of the scissor-type lifting frame 1 has a horizontally arranged lifting plate 1.1, and the lower end has a fixed plate 1.2 fixed to the top surface of the automatic feeding vehicle receiving hopper 100. The lifting plate 1.1 and the fixed plate 1.2 are connected as one unit by two sets of scissor fork frames 1.3. A pair of vertically upward cylinders 1.4 are also symmetrically arranged between the lifting plate 1.1 and the fixed plate 1.2. The telescopic ends of the two cylinders 1.4 extend and retract synchronously, thereby driving the lifting plate 1.1 to rise or fall smoothly through the cylinders 1.4, realizing the lifting function of the entire scissor-type lifting frame 1.

[0012] An interface 2 is provided on the lifting plate 1.1 for docking with the discharge port 200 of the mixing machine's hopper. Similarly, an opening should be provided on the fixed plate 1.2 to align with and connect to the receiving port at the top of the automatic feeding trolley's receiving hopper 100. The diameter of the interface 2 should be slightly larger than the outer diameter of the discharge port 200 of the mixing machine's hopper. To improve the compatibility between the interface 2 and the discharge port 200, a flared auxiliary alignment port 3 (larger at the top and smaller at the bottom) can be connected to the upper edge of the interface 2. This flared auxiliary alignment port 3 is coaxial with the interface 2. The device is designed to ensure that the interface 2 and the discharge port 200 of the mixing machine can be connected even if there is a slight deviation. A flexible dustproof sleeve 4 located inside the scissor lift frame 1 is connected to the lower edge of the interface 2. The lower end of the flexible dustproof sleeve 4 is connected to the receiving port of the automatic feeder hopper 100. When the scissor lift frame 1 descends, the flexible dustproof sleeve 4 can be compressed. When the scissor lift frame 1 rises, the flexible dustproof sleeve 4 unfolds, thereby forming a sealed dustproof channel connecting the interface 2 and the automatic feeder hopper 100.

[0013] During operation, the automatic feeding trolley, receiving a control command, automatically travels along the track to below the mixing machine's hopper. At this point, the automatic feeding trolley's receiving hopper 100 is directly below the mixing machine's hopper discharge port 200. Then, the scissor lift 1 automatically rises, and driven by the cylinder 1.4, the mating interface 2 on the lifting plate 1.1 accurately aligns with the mixing machine's hopper discharge port 200. Simultaneously, the rise of the lifting plate 1.1 causes the flexible dustproof sleeve 4 to unfold, thus creating a certain degree of seal for the mixing machine's hopper discharge. The dustproof sleeve 4 is used to overcome the movement gap between the automatic feeder hopper 100 and the mixer hopper discharge port 200, improve the sealing performance of the connection between the automatic feeder hopper 100 and the mixer hopper discharge port 200, and minimize the leakage of powder and material during the receiving process, preventing powder from scattering and polluting the environment. It has strong adaptability and practicality, and the entire lifting and docking device is durable and has low maintenance costs, providing a reliable guarantee for the automated batching and feeding process of refractory material processing and production.

[0014] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
