Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, specifically to a lubrication device and a labeling machine using the device. Background Technology

[0002] Labeling machines are devices that affix rolls of self-adhesive labels to PCBs, products, or prescribed packaging. Lubrication devices are an important mechanism to ensure the smooth operation of labeling machines.

[0003] A lubrication device is provided in which an oil tank is set below the lubrication points. An oil pump draws lubricating oil from the oil tank through an oil filter and pumps it to each lubrication point. The amount and pressure of the pumped oil are controlled by a throttle valve and an overflow valve. The lubricating oil lubricates the parts to be lubricated through the lubrication points and carries away the heat and debris generated during the operation of the lubrication parts. The lubricating oil then flows back to the oil tank through the return oil pipe.

[0004] The lubricating oil carries debris generated during the operation of the lubricating parts into the oil tank. Although the oil pump filters the lubricating oil through the oil filter when drawing it, the debris remains in the oil tank. It is difficult to thoroughly clean the debris in the oil tank when changing the lubricating oil, resulting in the newly replaced lubricating oil still containing impurities, affecting the lubrication effect, shortening the service life of the lubricating oil, and increasing the maintenance cost of the labeling machine.

This solves the problem that debris remains in the oil tank, making it difficult to thoroughly clean the debris in the oil tank when changing the lubricating oil. As a result, the newly replaced lubricating oil still contains impurities, affecting the lubrication effect, shortening the service life of the lubricating oil, and increasing the maintenance cost of the labeling machine.

[0021] By setting the No. 1 filter plate at an angle, when the impurities filtered by the No. 1 filter plate accumulate excessively, they fall to one side of the vertical plate. By setting the No. 2 filter plate at the top, when the impurities filtered by the No. 2 filter plate accumulate excessively, they fall to the other side of the vertical plate. This avoids the accumulation of impurities affecting the filtration performance and permeability of the filter box, and improves the service life of the filter box. Attached Figure Description

The first connecting groove 23 has a groove structure with an inverted isosceles trapezoidal cross section. A positioning block 24 is fixedly installed inside the first connecting groove 23.

[0035] Filter box 3 is located below connecting box 2. Filter box 3 has an oil outlet groove 32 and an oil inlet groove 33 on its surface, and a second connecting groove 31 on its surface. Inside filter box 3 is a filter chamber 35, which contains a vertical plate 36 and a first filter plate 37. The top surface of filter box 3 is flush with the bottom surface of connecting box 2. The surface of filter box 3 is marked with positive and negative markings to distinguish its installation direction. The second connecting groove 31 has a cross-section that communicates with the cross-section of the first connecting groove 23, and the second connecting groove 31 corresponds to the first connecting groove 23. Sealing gaskets 5 are installed inside both the oil outlet groove 32 and the oil inlet groove 33. A second sealing ring groove 34 is provided. The oil outlet 27 is inserted into the oil inlet groove 33, and the oil inlet 28 is inserted into the oil outlet groove 32. The sealing ring 6 protrudes from one side of the first sealing ring groove 29 and is set inside the second sealing ring groove 34. The filter chamber 35 is connected to the oil outlet groove 32 and the oil inlet groove 33. A second filter plate 38 is provided between the filter chamber 35 and the oil outlet groove 32. A vertical plate 36 is provided at the bottom of the filter chamber 35. The vertical plate 36 and the filter box 3 are integral structures. A first filter plate 37 is fixedly provided on the top of the vertical plate 36. The first filter plate 37 is fixedly connected to the inner wall of the filter chamber 35. The first filter plate 37 is set at an angle with the upper end close to the oil inlet groove 33 and the lower end close to the oil outlet groove 32.

[0036] The connecting post 4 is inserted into the second connecting groove 31 and the first connecting groove 23. The surface of the connecting post 4 is provided with a positioning groove 41. The connecting post 4 is slidably disposed inside the second connecting groove 31 and the first connecting groove 23. The end of the connecting post 4 is provided with an inlet angle 42. The positioning groove 41 passes through the connecting post 4. The connecting post 4 is slidably sleeved on the surface of the positioning block 24 through the positioning groove 41. The surface of the connecting post 4 is provided with an elastic piece 43. The elastic piece 43 is fixedly connected to the connecting post 4. The end of the elastic piece 43 is provided with a folded piece 44. The folded piece 44 and the elastic piece 43 are an integral structure. The folded piece 44 is snapped into the inside of the snap-fit ​​groove 22.

[0037] A labeling machine includes the aforementioned lubrication device.

[0038] In use, align the oil outlet groove 32 with the oil inlet 28, and align the oil inlet groove 33 with the oil outlet 27 and insert them, so that the oil outlet 27 and the oil inlet 28 are pressed against the surface of the sealing gasket 5. At this time, push the connecting column 4 so that the connecting column 4 is inserted into the interior of the second connecting groove 31 through the guide angle 42, pulling the filter box 3 close to the connecting box 2. At the same time, the oil outlet 27 and the oil inlet 28, along with the oil outlet groove 32 and the oil inlet groove 33, squeeze the sealing gasket 5 to form a seal. During the process of pushing the connecting column 4, the inverted folding piece 44 is squeezed by the connecting box 2, causing the elastic piece 43 to bend towards the connecting column 4. When the inverted folding piece 44 is aligned with the oil inlet groove 33, the elastic piece 43 causes the inverted folding piece 44 to snap into the interior of the snap-fit ​​groove 22, fixing the position of the connecting column 4, thereby fixing the filter box 3. At this time, the lubricating oil enters the first oil passage 25 through the upper return oil pipe 1, and then enters the filter chamber 35 through the oil outlet 27. Inside the filter chamber 35, the lubricating oil passes through filter plate 37 and filter plate 38 and enters the oil inlet 28. As the lubricating oil passes through filter plate 37 and filter plate 38, the debris and other impurities in the lubricating oil are filtered by filter plate 37 and filter plate 38. Because filter plate 37 is tilted, when a lot of impurities are filtered by filter plate 37, the impurities fall to one side of the vertical plate 36. When too many impurities are accumulated on the surface of filter plate 38, the impurities fall to the other side of the vertical plate 36. This effectively prevents the impurities from accumulating too much and affecting the permeability of filter plate 37 and filter plate 38, thus increasing the service life of filter box 3. The filtered lubricating oil enters the lower return oil pipe 11 through oil passage 26 and then flows back to oil tank 7. The temperature detector detects the temperature of the lubricating oil in oil tank 7 and then controls the cooler 71 and heating pad 72 to cool or add oil through the controller to ensure that the lubricating oil in oil tank 7 is kept within the set constant temperature.

[0039] After a certain period of use, press the elastic piece 43 to drive the folding piece 44 out of the snap-fit ​​groove 22, then pull the connecting post 4 out of the second connecting groove 31, and then pull the filter box 3 to separate the oil outlet groove 32 from the oil inlet groove 28 and the oil inlet groove 33 from the oil outlet groove 27. Then replace the filter box 3 with a new one.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
