Description

Technical Field

[0001] The invention relates to the technical field of horizontal kneading machines, in particular to a large-angle turning automatic feeding and discharging horizontal kneading machine. Background Art

[0002] The horizontal kneading machines currently used in the explosives industry are mainly the cylinder-turning kneading machines and the screw-discharging kneading machines. The cylinder-turning kneading machines use manual feeding, and the discharging uses a side water cylinder to drive the kneading cylinder to turn and unload. Due to the mechanical structure limiting the turning angle to less than ninety degrees, the material cannot be discharged cleanly and requires manual intervention. The screw-discharging kneading machine discharges the material outward by rotating the screw, but this discharge method will result in a small amount of material that cannot be discharged. Since the material is flammable and explosive, there is a safety hazard. The above two types of kneading machines cannot be automated. As the country has put forward the "dark factory" requirement for the explosives industry, the equipment must be isolated from the machine and the machine must be replaced by the machine. The horizontal kneading machine must realize automatic feeding, automatic discharging, and continuous production. Summary of the invention

[0035] The working principle is as follows: it is divided into three processes in sequence: adding, kneading and discharging, which are explained in detail below.

[0036] 1. Connect the solid feed port 29 and the liquid feed port 22 in the feeding device 14 to an external metering feeding auxiliary machine, and add the solid material and the liquid material into the kneading machine in a certain proportion; before adding the solid material, drive the sealing cover 21 to rotate through the cylinder 26 to open the solid feed port 29; during the feeding process, the main blade 16 and the auxiliary blade 17 do not work, and the kneading cylinder 6 is in a closed state, completing the feeding process.

[0037] 2. After the feeding is completed, the sealing cover 21 is closed, and the transmission device 1 is started, driving the 16 main blades and the 17 auxiliary blades to stir the materials according to the designed speed ratio; in order to better mix the materials, the two blades can change the rotation direction, and the material stirring process in the kneading cylinder can be remotely observed through a camera until the stirring meets the material property requirements and the kneading process is completed.

[0038] 3. When the material is stirred, the rotary cylinder 8 starts, and the kneading cylinder 6 is driven to flip at a large angle through the cylinder transmission shaft 7. The flip angle exceeds 135 degrees. The flip state is shown in Figure 4 During the turning process, the paddles can rotate forward and reverse at any time to discharge all the materials in the kneading cylinder 6. The discharging side of the kneading cylinder can be connected to a conveying auxiliary machine to transport the materials out of the workshop to complete the discharging process.

[0039] 4. When the material is exhausted, the rotary oil cylinder 8 drives the kneading cylinder 6 to return to the initial position. When the lower sealing seat 14 returns to the initial position, it squeezes the sealing strip 28 embedded in the upper sealing cover 18 to achieve sealing. At this time, the kneading cylinder 6 is closed.

[0040] Through the above, the horizontal kneading machine completes the three working procedures of feeding, kneading and discharging, and completes one working cycle; the human-machine isolation is realized during the operation of the horizontal kneading machine, the production process is continuous, the production efficiency is significantly improved, and personal safety is effectively guaranteed.
