Description

Technical Field

[0001] This invention relates to the field of line marking equipment technology, and in particular to a self-drip line marking ink fountain. Background Technology

[0002] As a fundamental step in construction, the efficiency of chalk line marking in surveying and setting out directly impacts the overall project schedule. To adapt to market demands and industry competition, improving the efficiency of chalk line marking has become a top priority. Existing chalk lines often have only one marking port, dispensing only one line at a time, which reduces efficiency. Furthermore, the limited ink tank capacity, constantly immersing the sponge in ink, not only easily leads to overflow but also causes excessive ink contamination on the lines, resulting in environmental pollution. Summary of the Invention

[0003] The purpose of this invention is to provide a self-drip ink fountain with two ink output directions, which ensures sufficient ink supply during the ink output process by wetting the ink-dipped sponge with self-drip water.

[0004] To achieve the above objectives, the present invention provides a self-drip ink fountain, comprising an outer shell and a first ink feeding mechanism, a second ink feeding mechanism, an ink-dipping mechanism, and a self-drip mechanism disposed within the outer shell. The first and second ink feeding mechanisms are disposed at the rear end of the inner part of the outer shell, the ink-dipping mechanism is located in front of the second ink feeding mechanism, and the self-drip mechanism is disposed above the ink-dipping mechanism. A first ink fountain rope from the first ink feeding mechanism and a second ink fountain rope from the second ink feeding mechanism pass through the ink-dipping mechanism respectively. The end of the first ink fountain rope extends from the front end of the outer shell, and the end of the second ink fountain rope extends from the side of the outer shell.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example

[0021] like Figure 1As shown, a self-drip ink fountain includes a housing 100 and a first ink feeding mechanism 500, a second ink feeding mechanism 400, an ink dipping mechanism, and a self-drip mechanism disposed within the housing 100. A first ink fountain rope 501 from the first ink feeding mechanism 500 and a second ink fountain rope 401 from the second ink feeding mechanism 400 respectively pass through the ink dipping mechanism.

[0022] The first wire feeding mechanism 500 and the second wire feeding mechanism 400 are located inside the rear end of the outer casing 100. Both the first wire feeding mechanism 500 and the second wire feeding mechanism 400 include a winding shaft 403, a return turntable 402, and a torsion spring. The winding shaft 403 is rotatably connected to the outer casing 100. A torsion spring is installed inside the winding shaft 403. The top end of the winding shaft 403 is connected to the return turntable 402 located on the top of the outer casing 100. The first ink fountain rope 501 and the second ink fountain rope 401 are respectively wound on the winding shaft 403. The specific structure of the winding shaft 403, the return turntable 402, and the torsion spring refers to the structure of existing wire feeding ink fountains, enabling them to have the function of automatic winding and return of the first ink fountain rope 501 and the second ink fountain rope 401.

[0023] like Figure 2 As shown, the ink-dipping mechanism is located in front of the second line-feeding mechanism 400, and the self-drip mechanism is located above the ink-dipping mechanism. The ink-dipping mechanism includes an ink-dipping tank 300, two ink-dipping sponges 301, a first ink top column 306, and a second ink top column 307. The ink-dipping chamber 300 is located in the middle of the outer casing 100. Two ink-dipping sponges 301 are stacked inside the ink-dipping chamber 300. A left inlet hole 302 and a right inlet hole 303 are provided in the middle of the rear end of the ink-dipping chamber 300. A first outlet hole 304 is provided in the middle of the front end of the ink-dipping chamber 300. A second outlet hole 305 is provided in the middle of the side of the ink-dipping chamber 300. A first ink fountain rope 501 enters through the left inlet hole 302 and exits through the first outlet hole 304. A second ink fountain rope 401 enters through the right inlet hole 303 and exits through the second outlet hole 305. The first ink fountain rope 501 and the second ink fountain rope 401 pass between the two ink-dipping sponges 301.

[0024] An arc-shaped partition plate 101 is provided between the first line feeding mechanism 500 and the second line feeding mechanism 400, and the front end of the arc-shaped partition plate 101 is connected to the ink dip chamber 300. Since the connection between the arc-shaped partition plate 101 and the ink dip chamber 300 is located between the left inlet hole 302 and the right inlet hole 303, there will be no interference between the first ink fountain rope 501 and the second ink fountain rope 401, thus avoiding mis-drawing lines when both ink fountain ropes are snapped and drawn simultaneously.

[0025] The first ink tip 306 and the second ink tip 307 are both located in the middle of the ink tank 300, with the first ink tip 306 near the front end of the ink tank 300. The first ink tip 306 and the second ink tip 307 have a limiting function. The first ink fountain rope 501 passes around the right side of the first ink tip 306, and the second ink fountain rope 401 passes around the left side of the second ink tip 307, guiding the forward direction of the ink fountain ropes and maintaining the tension of the ink fountain ropes.

[0026] like Figure 3 As shown, both the first ink ejector post 306 and the second ink ejector post 307 include an upper ejector rod 309, a lifting spring 312, a spring seat 311, and a core 310. The top of the upper ejector rod 309 is fitted with a rubber stopper 308. The upper ejector rod 309 is nested outside the core 310, and the bottom end of the core 310 is fixed to the center of the spring seat 311. The lifting spring 312 surrounds the bottom end of the core 310 and is located inside the spring seat 311, below the upper ejector rod 309. The lifting spring 312 provides an upward lifting force on the upper ejector rod 309, and the up-and-down movement of the upper ejector rod 309 does not affect the extraction and retraction of the ink cord.

[0027] The self-drip mechanism includes an ink reservoir 200, an ink-filling cap 204, a first ink dispensing unit 202, and a second ink dispensing unit 203. The ink reservoir 200 is embedded in the top center of the outer casing 100. An ink filling port is located in the center of the top cover 201 of the ink reservoir 200, and the ink-filling cap 204 covers the ink filling port. Opening the ink-filling cap 204 allows ink to be added to the ink reservoir 200. The bottom edge of the ink reservoir 200 abuts against the top edge of the ink-dipping tank 300 to prevent ink from overflowing from around the ink-dipping tank 300.

[0028] The bottom surface of the ink reservoir 200 is provided with two ink drip holes, and guide columns 209 are provided around the bottom surface of the ink drip holes. The ink falls along the guide columns 209, which can prevent the ink from spreading along the bottom surface of the ink reservoir 200 to the edge. The two guide columns 209 are located above the first ink top column 306 and the second ink top column 307, respectively. The top of the rubber gasket plug 308 is blocked below the guide columns 209. Under the elastic force of the lifting spring 312, the guide columns 209 are blocked, which can isolate the ink reservoir 200 from the ink dip container 300 and prevent ink from falling.

[0029] The first ink dispensing unit 202 is positioned opposite to the first ink top post 306, and the second ink dispensing unit 203 is positioned opposite to the second ink top post 307. Each ink dispensing unit has the function of dispensing ink. Both the first ink dispensing unit 202 and the second ink dispensing unit 203 include a pressing rod 208 and an adjusting end cap 205. The adjusting end cap 205 is located above the top surface of the ink reservoir 200 and is threadedly connected to the fixing post 207. An anti-leakage rubber gasket 206 is provided inside the adjusting end cap 205, pressing against the top of the fixing post 207 to prevent ink from overflowing between the fixing post 207 and the adjusting end cap 205. The top of the pressing rod 208 passes through the fixing post 207 and is fixedly connected to the center of the adjusting end cap 205. The bottom of the pressing rod 208 passes through the guide post 209 and contacts the rubber gasket plug 308. By rotating the adjusting end cap 205, the position of the bottom end of the lowering rod 208 can be changed. When the lowering rod 208 descends, it applies pressure to the upper push rod 309, forcing the rubber gasket plug 308 to leave the guide column 209. At this time, the ink in the ink pool 200 begins to drip automatically, thereby wetting the ink sponge 301 and evenly applying ink to the ink fountain rope. After the lowering rod 208 rises, the lifting spring 312 lifts the upper push rod 309, resealing the guide column 209 and reducing ink waste.

[0030] To prevent ink from failing to flow out of the ink reservoir 200 under atmospheric pressure, an air pressure balance hole can be installed at the top of the ink reservoir 200 to allow the ink to flow smoothly. The ink release time through the ink dispensing unit is not limited to before or during the line drawing operation, thereby ensuring that the ink-dipped sponge 301 in the ink-dipping tank 300 has a suitable ink saturation and reducing ink waste.

[0031] The front end of the outer casing 100 is provided with a first wire feeding port 103, and the side of the outer casing 100 is provided with a second wire feeding port 104. The second wire feeding port 104 is arranged opposite to the first wire outlet 304 and opposite to the second wire outlet 305. The first ink fountain rope 501 passes through the first wire feeding port 103 and is used for wire snapping measurement; the second ink fountain rope 401 passes through the second wire feeding port 104 and is used for wire snapping measurement. Guide channels 105 are provided on both sides of the interior of the first wire feeding port 103 and the second wire feeding port 104. The guide channels 105 are in contact with the ink dip chamber 300. The shape of the fixing post 102 is adapted to the shape of the guide channel 105. After the first ink fountain rope 501 and the second ink fountain rope 401 are retracted, the fixing post 102 is stored in the end of the guide channel 105 in the non-working state.

[0032] Therefore, the present invention adopts a self-drip ink fountain with the above-mentioned structure, which stores the ink line through the first ink line dispensing mechanism 500 and the second ink line dispensing mechanism 400 respectively, and can dispense the ink line in two directions simultaneously, thereby improving the efficiency of the spring-loaded line drawing. The ink dip hopper 300 dips the ink line of the ink fountain into ink, and the ink pool 200 stores the ink. The ink top column set in the ink dip hopper 300 cooperates with the ink dispensing unit set in the ink pool 200 to achieve self-drip wetting of the ink dip sponge 301, thereby improving the stability of ink dripping and ensuring sufficient ink supply during the ink line dispensing process.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
