Abstract
Description
Technical Field
[0001] This utility model relates to the field of tool lubrication technology, specifically to a special oil can device for files and saws. Background Technology
[0002] In the stripping process of wood processing, band saw blades are commonly used for cutting. To ensure smooth sawing and prevent saw jamming, a toothed saw must be used to shape the saw blade, creating a kerf slightly wider than the saw body. Due to the high friction during sawing, the saw blade also needs to be lubricated. Currently, the common method is to manually apply machine oil using cotton yarn, using about 200 grams each time. While this traditional lubrication method achieves the basic function, it has significant drawbacks: firstly, it consumes a large amount of machine oil, resulting in resource waste; secondly, it is prone to dripping and splashing during operation, polluting the work environment and increasing the difficulty of cleaning and manual labor.
[0003] Therefore, existing technologies need further development. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a special oil can device for files and saws. This solves the technical problems in the related technology where wiping saw blades with cotton yarn soaked in machine oil results in a large amount of machine oil being used, which easily leads to resource waste. Furthermore, the oil is prone to dripping and splashing during operation, polluting the working environment and increasing the difficulty of cleaning and the burden on manpower.
[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A special oil can device for filing saws is provided, comprising: a first handheld part; an application cylinder extending in a preset direction, with the first handheld part installed at the bottom of the application cylinder; a lubrication cavity and a lubrication port communicating with the lubrication cavity, the lubrication port extending in the extending direction of the application cylinder, the lubrication port being used to place the saw teeth of the saw blade; cotton yarn placed in the lubrication cavity, the cotton yarn being used to absorb machine oil; wherein, by placing the lubrication port on the saw teeth of the saw blade, and by moving the application cylinder to bring the cotton yarn absorbing machine oil in the lubrication cavity into contact with the saw teeth of the saw blade, an application treatment is performed.
[0006] Furthermore, there are two first hand-held parts, which are spaced apart along the radial direction of the applicator; each of the two first hand-held parts is provided with a grip groove, which extends along a preset arc trajectory.
[0007] Furthermore, the oil can device for files and saws also includes: a cotton yarn oil filter assembly, which further includes: a conical extrusion cylinder. The conical extrusion cylinder is installed at one end of the coating cylinder. The conical extrusion cylinder has an extrusion chamber, as well as a yarn inlet and a yarn outlet connected to the extrusion chamber. The yarn inlet is located at the end of the extrusion chamber closer to the lubrication chamber, and the yarn outlet is located at the end of the extrusion chamber farther from the lubrication chamber. The inner diameter of the extrusion chamber gradually decreases from the yarn inlet to the yarn outlet. The lubrication chamber is connected to the yarn inlet to move the cotton yarn in the lubrication chamber from the yarn inlet to the yarn outlet of the conical extrusion cylinder, thereby extruding and filtering the oil from the cotton yarn through the gradually decreasing inner diameter.
[0008] Furthermore, the file and saw oil can device also includes: a cotton yarn traction assembly, which includes: a movable rod extending along the extension direction of the coating cylinder, at least a portion of the movable rod being movably disposed within the lubrication chamber and the extrusion chamber, the movable rod being used to drive the cotton yarn to move within the coating cylinder; and a flexible hook disposed at one end of the movable rod located within the lubrication chamber, the flexible hook being used to connect with the cotton yarn.
[0009] Furthermore, the cotton yarn traction assembly also includes a second handhold, which is mounted on the end of the movable rod away from the flexible hook.
[0010] Beneficial effects:
[0011] 1. The extension direction of the coating tube is designed to match the extension structure of the lubrication port, forming a guide channel that matches the shape of the saw blade teeth. The cotton yarn filled in the lubrication chamber continuously absorbs machine oil through capillary action. When the lubrication port is fitted onto the saw teeth, the operator can achieve linear contact lubrication between the cotton yarn and the saw teeth by moving the first hand. This effectively solves the problems of large oil consumption and resource waste when wiping the saw blade with cotton yarn dipped in machine oil, as well as the problems of easy dripping and splashing during operation, which pollute the working environment and increase cleaning difficulty and manual burden.
[0012] 2. The tapered design of the compression chamber causes the cotton yarn to be subjected to gradually increasing radial pressure during movement; this compression process gradually squeezes out the oil absorbed by the cotton yarn and then flows back into the lubrication chamber, effectively preventing the oil absorbed by the cotton yarn from dripping or being wasted when changing the cotton yarn.
[0013] 3. The moving rod travels along the axial direction of the coating cylinder, covering the entire section of the lubrication chamber and the extrusion chamber; the flexible hook is a hook-shaped structure made of elastic material, which can achieve reliable connection without damaging the cotton yarn fibers, effectively realizing the old yarn replacement operation.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0019] According to an embodiment of this utility model, a special oil can device for files and saws is provided; please refer to [link / reference needed]. Figures 1 to 2 The device includes: a first hand-held part 1; an application tube 2, which extends in a preset direction and has the first hand-held part 1 installed at its bottom; a lubrication cavity 3 and a lubrication port 4 communicating with the lubrication cavity 3, which extends in the extension direction of the application tube 2 and is used to place the saw teeth of the saw blade; cotton yarn is placed in the lubrication cavity 3 and is used to absorb machine oil; wherein, by placing the lubrication port on the saw teeth of the saw blade, the application tube 2 is moved to bring the cotton yarn that has absorbed machine oil in the lubrication cavity 3 into contact with the saw teeth of the saw blade to perform the application treatment.
[0020] By adopting the above technical solution, the extension direction design of the coating tube 2 is matched with the extension structure of the lubrication port 4 to form a guide channel that matches the shape of the saw blade teeth. The cotton yarn filled in the lubrication cavity 3 continuously absorbs the machine oil through capillary action. When the lubrication port 4 is fitted onto the saw teeth, the operator can achieve linear contact lubrication between the cotton yarn and the saw teeth by moving the first hand-held part 1. This effectively solves the problems of large machine oil consumption when the cotton yarn is dipped in machine oil to wipe the saw blade, which easily leads to resource waste, and easy dripping and splashing during operation, polluting the working environment and increasing cleaning difficulty and manual burden.
[0021] Please refer to Figure 1 There are two first hand-held parts 1, which are spaced apart along the radial direction of the applicator 2; each of the two first hand-held parts 1 has a hand grip groove 6, which extends along a preset arc trajectory.
[0022] By adopting the above technical solution, the two first hand grips 1 are symmetrically distributed radially along the coating tube 2, and together with the hand grip grooves 6 extending along the preset arc trajectory, they form an ergonomic double grip point. This structure allows the operator to stably control the movement trajectory of the coating tube 2, and effectively prevents the tube from deflecting, especially in long-distance push-pull operations, ensuring that the lubrication port 4 and the serrated part maintain a constant contact pressure. When not in use, the coating tube 2 can be placed in a designated position by using the two hand grips 1, without worrying about oil spillage.
[0023] Please refer to Figure 1 and Figure 2 The file and saw oil can device also includes: a cotton yarn oil filter assembly, which further includes: a conical extrusion cylinder 7. The conical extrusion cylinder 7 is installed at one end of the coating cylinder 2. The conical extrusion cylinder 7 has an extrusion chamber 8, and a yarn inlet 9 and a yarn outlet 10 connected to the extrusion chamber 8. The yarn inlet 9 is located at the end of the extrusion chamber 8 near the lubrication chamber 3, and the yarn outlet 10 is located at the end of the extrusion chamber 8 away from the lubrication chamber 3. The inner diameter of the extrusion chamber 8 gradually decreases from the yarn inlet 9 to the yarn outlet 10. The lubrication chamber 3 is connected to the yarn inlet 9 to move the cotton yarn in the lubrication chamber 3 from the yarn inlet 9 of the conical extrusion cylinder 7 to the yarn outlet 10 of the conical extrusion cylinder 7, and to extrude oil by squeezing the cotton yarn through the gradually decreasing inner diameter.
[0024] By adopting the above technical solution, the tapered design of the extrusion chamber 8 causes the cotton yarn to be subjected to gradually increasing radial pressure during movement; this compression process gradually squeezes out the oil adsorbed by the cotton yarn and then flows back into the lubrication chamber 3, effectively preventing the problem of oil adsorbed by the cotton yarn dripping or being wasted when changing the cotton yarn.
[0025] Please refer to Figure 2 The file and saw oil can device also includes: a cotton yarn traction assembly, which includes: a movable rod 11, which extends along the extension direction of the coating cylinder 2, and at least a portion of the movable rod 11 is movably disposed in the lubrication chamber 3 and the extrusion chamber 8, and the movable rod 11 is used to drive the cotton yarn to move within the coating cylinder 2; and a flexible hook 12, which is disposed at one end of the movable rod 11 located in the lubrication chamber 3, and the flexible hook 12 is used to connect with the cotton yarn.
[0026] By adopting the above technical solution, the moving stroke of the movable rod 11 along the axial direction of the coating cylinder 2 covers the entire section of the lubrication chamber 3 and the extrusion chamber 8; the flexible hook 12 adopts a hook-shaped structure made of elastic material, which can achieve reliable connection without damaging the cotton yarn fibers and effectively realize the old yarn replacement operation.
[0027] Please refer to Figure 1 and Figure 2 The cotton yarn traction assembly also includes a second handhold 13, which is mounted on the end of the movable rod 11 away from the flexible hook 12.
[0028] By adopting the above technical solution, the second hand-held part 13 is connected to the end of the movable rod 11 to form an independent operating interface. This structure physically isolates the cotton yarn traction action from the lubrication operation of the coating cylinder 2, allowing the operator to adjust the cotton yarn displacement by controlling the second hand-held part 13 with one hand, thus avoiding the drawback of needing to pause lubrication operations for maintenance in traditional devices.
[0029] Working principle:
[0030] 1. Guiding and Positioning Stage:
[0031] The operator aligns the lubrication port 4 of the coating tube 2 with the saw teeth of the saw blade and inserts it along the extension direction of the coating tube 2; the extension structure of the lubrication port 4 matches the shape of the saw teeth, ensuring that the saw teeth are fully embedded in the lubrication port 4, forming a stable linear contact relationship.
[0032] 2. Oil storage and adsorption stage:
[0033] The cotton yarn in the lubrication chamber 3 continuously adsorbs the stored engine oil through capillary action; the cotton yarn remains loose in a free state, forming a saturated adsorption layer with a high oil storage capacity, providing sufficient oil reserves for subsequent lubrication.
[0034] 3. Dynamic lubrication stage:
[0035] The operator holds the two first handpieces 1 with both hands and moves the coating cylinder 2 at a constant speed along the extension direction of the saw blade. The dense cotton yarn in the lubrication port 4 continuously rubs against the surface of the saw teeth, completing the lubrication process.
[0036] 4. Squeeze and filter stage:
[0037] The operator pulls the movable rod 11 through the second hand part 13, eventually forming a dense and uniform oil film layer.
[0038] 5. Cotton yarn maintenance stage;
[0039] When the cotton yarn is worn down to the point where it needs to be replaced:
[0040] The operator holds the second hand part 13 with one hand and pulls the movable rod 11 outward. The flexible hook 12 pulls the cotton yarn from the lubrication chamber 3 to the conical extrusion cylinder 7. After the cotton yarn enters the extrusion chamber 8 through the yarn inlet 9, as the inner diameter of the extrusion chamber 8 gradually decreases, the cotton yarn fibers are radially compressed, excess machine oil is squeezed out and flows back to the lubrication chamber 3, and then it is taken out from the yarn outlet 10.
[0041] Finally, insert the new cotton yarn into the lubrication chamber 3 through the lubrication port 4.
