Description

Technical Field

[0001] This utility model relates to the field of hydraulic discharge machine technology, and in particular to a pressure-adjustable hydraulic discharge machine. Background Technology

[0002] The pressure-adjustable hydraulic discharge machine is an automated discharge device that uses a hydraulic system as its power source and controls the extrusion intensity of the material in the hopper by adjusting the hydraulic pressure parameters. This allows for on-demand adjustment of discharge pressure, flow rate, and speed. It is widely used in automated material discharge scenarios in the chemical, electronics, food, and pharmaceutical industries, and has significant advantages such as controllable pressure, uniform discharge, and high efficiency.

[0003] Existing pressure-adjustable hydraulic discharge machines ensure uniform and stable discharge of various materials through dynamic pressure adjustment, reducing material waste and equipment blockage risks. However, the material cylinder is only supported at the bottom, making it prone to displacement and swaying, affecting discharge accuracy and potentially causing collisions with the equipment. Current technology involves machining positioning pins and positioning holes at corresponding positions on the bottom support and the material cylinder. During cylinder changes, the positioning pins are inserted into the positioning holes for quick and accurate positioning, allowing the material cylinder to align rapidly with the hydraulic discharge mechanism, reducing debugging time and improving cylinder changing efficiency. However, during frequent cylinder changes, the positioning pins and holes are repeatedly inserted and removed, leading to wear and a decrease in positioning accuracy. Regular replacement and maintenance are required, increasing equipment maintenance costs and downtime, and affecting production continuity. Utility Model Content

[0033] The clamping mechanism 6 includes a slide groove 601. Multiple slide grooves 601 are equidistantly opened around the top wall of the base 1. A slider 602 is slidably connected to the inner wall of the slide groove 601. A clamping block 603 is fixedly connected to the top wall of the slider 602. A rack 6046 pushes the slider 602 to slide in the slide groove 601. The slider 602 drives the clamping block 603 to clamp and fix the cylinder 5. A drive assembly 604 is installed inside the base 1.

[0034] Drive assembly 604 includes a motor 6041, which is fixedly connected inside the base 1. A gear 6042 is fixedly connected to the output end of the motor 6041, driving the gear 6042 to rotate.

The second gear 6045 meshes with the rack 6046. The second gear 6045 drives the rack 6046 to move towards the center at the same time. The cylinder 5 is set on the adjacent side of the outer wall of the multiple clamping blocks 603. The gear disk 6042 is set on the adjacent side of the outer wall of the multiple first gears 6043.

[0035] Specifically, the cylinder 5 is placed on the base 1, and then the motor 6041 is started. The operation of the motor 6041 drives the gear plate 6042 to rotate, which in turn causes the four gears 6043 to rotate. The gears 6043 drive the gears 6045 to rotate through the connecting shaft 6044. The gears 6045 cause the rack 6046 to move towards the center. The movement of the rack 6046 pushes the slider 602 to slide in the groove 601. The slider 602 then drives the clamping block 603 to clamp and fix the cylinder 5.

Finally, by tightening the bolts 805 and nuts 806, the semicircular ring one 803 and semicircular ring two 804 tightly clamp the high-pressure conveying pipe 7 and the connection port 801, further compressing the sealing gasket 802 to enhance the sealing effect, ensuring a stable connection of the high-pressure conveying pipe 7 during hydraulic discharge and preventing leakage.

When changing cylinders, there is no need for repeated manual alignment and adjustment, which can shorten the production change time and improve the production change efficiency.

[0042] First, the connection port 801 between the high-pressure conveying pipe 7 and the hydraulic cylinder 3 is engaged, and the sealing gasket 802 on the connection port 801 initially isolates the gaps.
