Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a gearbox oil return device for a YJ27 connector nozzle bar supply system. Background Technology

[0002] The lubricating oil in the gearbox of the YJ27 connector nozzle supply system needs to be cleaned and replaced once every six months. There is a 10mm external hex bolt at the bottom of the gearbox. During the lubricating oil replacement process, use an external hex tool to remove the 10mm external hex bolt.

[0003] Due to the confined space, disassembling the external hex bolts is extremely inconvenient. Since the bolts are not visible, one must first feel and touch them by hand before using tools to grope and remove them. As the bolts near removal, the lubricating oil inside the gearbox begins to flow into the cramped machine space and onto the floor below, making the entire cleaning process very difficult and taking approximately 1.5 hours. Furthermore, during production maintenance of this gearbox, the overflowing lubricating oil contaminates cigarettes on the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a gearbox oil return device for the YJ27 connector nozzle rod supply system, which solves the problem of inconvenient gearbox cleaning caused by structural defects in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a gearbox oil return device for a YJ27 nozzle rod supply system, including a gearbox body and a lubricating oil pipe, one end of the lubricating oil pipe is provided with an external thread, the bottom of the gearbox body is provided with a threaded hole, the threaded end of the lubricating oil pipe is screwed into the threaded hole and communicates with the interior of the gearbox body, and the other end of the lubricating oil pipe is detachably equipped with a plug, the plug being used to seal the lubricating oil pipe.

[0006] With this structural design, the external hexagonal bolt at the bottom of the gearbox of the YJ27 connector nozzle supply system is replaced with a lubricating oil pipe with an internal thread on one end and an external thread on the other. The lubricating oil pipe is threaded to the bottom of the gearbox, and the other end of the lubricating oil pipe is plugged with a plug.

A second rubber sealing ring 12 is glued and fixed to the inner side wall of the through hole 11. The bottom wall of the mounting base 2 has an upwardly recessed threaded hole 21. A through hole 22 is opened on the bottom wall of the threaded hole 21, which connects the through hole 11 and the threaded hole 21. The axes of the through hole 22, the through hole 11, and the threaded hole 21 are collinear.

[0034] The lubricating oil pipe includes a flexible hose 4. In this embodiment, the flexible hose 4 is preferably a corrugated metal hose. A first connector 3 is fixed to the top end of the flexible hose 4, and a second connector 5 is fixed to the bottom end of the flexible hose 4. Both the first connector 3 and the second connector 5 are metal connectors. The first connector 3 includes a straight section 31 and a tapered section 32. The straight section 31 is welded to the top end of the flexible hose 4. The tapered section 32 is integrally formed and fixed to the end of the straight section 31 away from the flexible hose 4. An annular block 33 is fixedly sleeved on the outer wall of the straight section 31. The outer wall of the annular block 33 is provided with external threads. The shape of the tapered section 32 matches the through hole 11. The inner wall of the second connector 5 is provided with internal threads. A plug 6 is detachably installed in the second connector 5. The plug 6 is used to seal the lubricating oil pipe. During installation, the first connector 3 is fixedly installed at the bottom of the gearbox body 1 by threading the annular block 33 with the mounting base 2. At this time, the top of the tapered section 32 extends into the interior of the gearbox body 1, and the first connector 3 is connected to the gearbox body 1. The outer wall of the tapered section 32 is tightly fitted with the second rubber sealing ring 12 on the inner wall of the through hole 11, which increases the sealing performance between the first connector 3 and the gearbox body 1 and prevents the lubricating oil inside the gearbox body 1 from leaking out from the gap.

[0035] A first rubber sealing ring 34 is provided between the annular block 33 and the bottom wall of the threaded hole 21. In this embodiment, the first rubber sealing ring 34 is glued to the top wall of the annular block 33. When the first connector 3 is threaded onto the mounting base 2, the first rubber sealing ring 34 is tightly attached between the bottom wall of the threaded hole 21 and the top wall of the annular block 33, which can further increase the sealing performance between the first connector 3 and the mounting base 2 and prevent lubricating oil leakage.

[0036] An anti-loosening nut 7 is provided between the straight section 31 and the mounting base 2.

[0037] The second connector 5 has an internal flow channel. The plug 6 includes a bolt 61 and a conical block 62. The bolt 61 includes a nut and a screw. The conical block 62 is fixedly installed on the free end of the screw. The diameter of the conical block 62 gradually increases along the flow direction of the lubricating oil in the flow channel of the second connector 5. A third rubber sealing ring 63 is provided between the conical block 62 and the inner wall of the second connector 5. The third rubber sealing ring 63 is glued to the outer wall of the conical block 62. When the bolt 61 is tightened and fixed to the second connector 5, the outer wall of the conical block 62 and the third rubber sealing ring 63 are tightly fitted to the inner wall of the second connector 5, which increases the sealing performance of the connection between the plug 6 and the second connector 5 and prevents lubricating oil leakage.

[0038] Working principle:

[0039] The first connector 3 of the lubricating oil pipe is threaded onto the mounting base 2. The lubricating oil pipe is connected to the inside of the gearbox 1. Under normal conditions, the lubricating oil inside the lubricating box flows into the lubricating oil pipe and the second connector 5 of the lubricating oil pipe is sealed by the plug 6. The lubricating oil pipe is placed in the narrow space at the bottom of the gearbox 1.

[0040] When the lubricating oil in the gearbox of the YJ27 connector nozzle system needs cleaning and replacement, the free end of the lubricating oil pipe is pulled out, the plug 6 is removed, and the system is cleaned with water. The remaining lubricating oil and cleaning water in the pipe are then collected in an additional container to prevent contamination of the cigarette during gearbox maintenance. The improved oil return device facilitates overall maintenance and disassembly, significantly reducing maintenance time and improving efficiency. Although the improvement is simple, the results are significant, effectively increasing equipment operating rate and ensuring product quality.
