Description

Technical Field

[0001] This utility model belongs to the field of marking technology, specifically relating to an ink supply device for marking the end of a rubber tube. Background Technology

[0002] Currently, in the production process of rubber hoses, it is generally necessary to use a marking machine to mark the brand and model number on the end of the hose.

[0003] Existing marking equipment, such as Chinese Patent No. CN112976830A, discloses a hydraulic hose marking device, which includes a base, a pigment chamber, a marking component, a dynamic pressure component, a transmission component, and a synchronous lifting component. The pigment chamber is placed on the upper surface of the base, and the marking component is set inside the pigment chamber. That is, the prior art uses a marking wheel to directly pick up pigment from the pigment chamber for marking.

[0004] However, in actual production, the existing pigment supply method results in a large pigment coverage area on the marking wheel, which easily leads to pigment contamination in non-patterned areas of the marking wheel. This not only wastes pigment, but also causes the pigment to become continuous when the marking pattern is discontinuous, resulting in a blurry pattern on the tube and poor marking effect. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved ink supply device for marking the end of a rubber tube.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An ink supply device for marking the end of a rubber hose includes a feeding platform with an ink-adhesion station, an ink storage tank and a sealing component movably disposed on the feeding platform, and a driver. The ink-adhesion station has an ink supply groove recessed inward from the upper surface of the feeding platform to form a marking pattern and for the marking head to adhere to the ink. The ink storage tank has an ink discharge port formed from its bottom that fits against the upper surface of the feeding platform. The sealing component forms a sealing barrier area around the ink discharge port on the upper surface of the feeding platform. The driver drives the ink storage tank and the sealing component to reciprocate synchronously towards or away from the ink-adhesion station to drive the ink discharge port and the ink supply groove to align and connect vertically or to open the ink supply groove.

[0008] Preferably, the sealing component includes a sleeve fitted around the outer periphery of the ink reservoir and a sealing ring disposed at the bottom of the sleeve to form a sealing barrier area.

[0009] Preferably, the inner wall of the sleeve fits against the outer wall of the ink reservoir; and / or, the center lines of the ink reservoir, the sleeve, and the sealing ring coincide. This simplifies installation and facilitates synchronization of the movement of the sealing components and the ink reservoir.

[0010] Furthermore, the sealing component also includes a counterweight fitted around the outer periphery of the ink reservoir. The counterweight presses against the top of the sleeve to keep the sealing ring in contact with the upper surface of the feeding platform. This ensures a tight fit between the sealing ring and the feeding platform, preventing loosening during movement and ink leakage.

[0011] Preferably, the ink reservoir is open from the top, forming an ink filling port. This allows for easy monitoring of the remaining ink level and timely replenishment.

[0012] Preferably, the driver includes a transmission bracket and a drive component that drives the transmission bracket to reciprocate, wherein the transmission bracket is connected to the lower part of the ink reservoir or sealing component via a connecting strip. This ensures smooth movement and prevents ink spillage due to ink reservoir shaking.

[0013] Preferably, the transmission bracket includes a frame body connected to the drive component and an anti-tipping bar assembly fixedly mounted on the frame body for preventing the ink reservoir from tipping over in the direction of movement, wherein the anti-tipping bar assembly is positioned close to the upper end of the ink reservoir. This prevents the ink reservoir from accidentally tipping over, improving reliability.

[0014] Specifically, the anti-tipping bar assembly includes a U-shaped bar and a crossbar detachably connected to the open end of the U-shaped bar to form an anti-tipping space, within which the ink reservoir is located. This provides 360° protection against tipping of the ink reservoir during movement and is easy to assemble and disassemble.

[0015] Furthermore, the open end of the U-shaped bar faces away from the ink-sticking station, and the crossbar extends diagonally inward and downward from the middle to form a connecting strip. Here, when the ink reservoir is moved to the ink-sticking station, space above the ink-sticking station can be saved to facilitate the installation and movement of the marking head.

[0016] In addition, the ink supply unit also includes an ink recovery tank, with a feeding platform installed inside the tank. This allows for the recovery of any small amounts of ink that leak out.

[0017] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] Existing ink supply methods result in a large ink coverage area on the marking wheel, easily leading to ink contamination in non-patterned areas. This not only wastes ink but also causes ink to become continuous when marking discontinuous patterns, resulting in blurry patterns on the tubing and poor marking quality. This application addresses these shortcomings by comprehensively designing the ink supply device for marking the tubing end. The device involves attaching the ink reservoir to the upper surface of the supply platform from the bottom ink discharge port and adding ink to the reservoir. A sealing component forms a circumferential sealing barrier around the ink discharge port on the upper surface of the supply platform to prevent ink leakage. Then, a driver synchronously propels the ink reservoir and sealing component to the ink application station. In this invention, when the ink discharge port at the bottom of the ink reservoir aligns with the ink supply trough at the ink-sticking station, ink automatically fills the trough from top to bottom, forming the marking pattern. Then, a driver moves the ink reservoir and sealing component synchronously away from the ink-sticking station to open the ink supply trough. At this point, only the ink supply trough contains ink, allowing the marking head to accurately apply ink for marking. Therefore, compared to existing technologies, this invention, based on the sealing component maintaining a circumferential seal around the ink discharge port, achieves vertical alignment and connection between the ink discharge port and the ink supply trough for ink filling and opening the ink supply trough for precise ink supply as the ink reservoir moves. This effectively controls ink consumption and saves costs. Simultaneously, it significantly reduces ink residue in non-patterned areas of the feeding platform, effectively improving marking quality and flexibly adapting to various continuous or discontinuous markings.

[0034] See Figures 1 to 3 As shown, the ink supply device for marking the end of the hose in this embodiment includes a feeding platform 1 with an ink-adhesion station w, an ink storage tank 2 and a sealing component 3 respectively movably disposed on the feeding platform 1, and a driver 4.

[0035] Specifically, the upper surface of the feeding platform 1 is a horizontal and smooth metal surface, and the ink-sticking station w has an ink supply groove c that is recessed inward from the upper surface of the feeding platform 1 to form a marking pattern and supply ink to the marking head T. In this embodiment, the marking pattern is two line segments spaced side by side. Therefore, the ink supply groove c is composed of two grooves spaced side by side. The marking head T can accurately pick up ink from the ink supply groove c from the marking end formed at the bottom.

[0036] In this example, the ink reservoir 2 is a vertical cylindrical tank, and the ink reservoir 2 has an ink discharge port k1 that fits the upper surface of the feeding platform 1 from the bottom, and an ink filling port k2 that is open from the top. Ink can be added directly into the ink reservoir 2 by manual labor or a robotic arm through the ink filling port k2.

[0037] In this example, the sealing component 3 forms a sealing barrier area q around the ink discharge port k1 on the upper surface of the feeding platform 1, so as to form a barrier around the ink discharge port k1 and prevent ink leakage from the ink storage tank 2.

[0038] In some specific embodiments, the sealing component 3 includes a sleeve 30 fitted around the outer periphery of the ink reservoir 2, a sealing ring 31 disposed at the bottom of the sleeve 30 and forming a sealing barrier area q, and a counterweight 32 fitted around the outer periphery of the ink reservoir 2. The inner wall of the sleeve 30 is in contact with the outer wall of the ink reservoir 2, and the center lines of the ink reservoir 2, sleeve 30, and sealing ring 31 coincide. This design simplifies installation and facilitates synchronization of the movement of the sealing component and the ink reservoir. The sealing ring 31 fits against the upper surface of the feeding platform 1 and can be made of any conventional sealing material, allowing it to slide along a smooth metal surface while forming a sealing barrier.

[0039] Furthermore, the counterweight 32 is pressed onto the top of the sleeve 30 to keep the sealing ring 31 in contact with the upper surface of the feeding platform 1. This ensures a tight fit between the sealing ring and the feeding platform, preventing loosening during movement and ink leakage. The mass of the counterweight 32 can be selected according to actual needs.

[0040] In this example, the driver 4 drives the ink reservoir 2 and the sealing component 3 to reciprocate synchronously towards or away from the ink-sticking station w, so as to drive the ink discharge port k1 and the ink supply tank c to be aligned and connected vertically or to open the ink supply tank c.

[0041] In some specific embodiments, the driver 4 includes a transmission bracket 40 and a drive member 41 that drives the transmission bracket 40 to reciprocate, wherein the transmission bracket 40 is connected to the lower part of the sleeve 30 via a connecting strip d. This ensures smooth movement and prevents ink spillage caused by shaking of the ink reservoir.

[0042] The transmission bracket 40 includes a bracket body 400 connected to the drive member 41, and an anti-tilt bar assembly 401 fixedly mounted on the bracket body 400 to prevent the ink reservoir 2 from tipping over in the direction of movement. The anti-tilt bar assembly 401 is positioned near the upper end of the ink reservoir 2. This prevents the ink reservoir from accidentally tipping over, improving reliability.

[0043] Specifically, the anti-tilt bar assembly 401 includes a U-shaped bar g1 and a crossbar g2 detachably connected to the open end of the U-shaped bar g1 to form an anti-tilt space, wherein the ink reservoir 2 is located within the anti-tilt space. This design effectively prevents the ink reservoir from tipping over during movement at 360° angles and is easy to assemble and disassemble.

[0044] Furthermore, the open end of the U-shaped bar g1 faces away from the ink-sticking station w, and the crossbar g2 extends diagonally inward and downward from the middle to form the connecting strip d. Here, when the ink reservoir is moved to the ink-sticking station, the space above the ink-sticking station can be saved to facilitate the installation and movement of the marking head.

[0045] For ease of implementation, the drive unit 41 is a rodless cylinder, the feeding platform 1 is located above the rodless cylinder, and the frame body 400 is connected to the rodless cylinder and located on opposite sides of the feeding platform 1.

[0046] In addition, the ink supply device also includes an ink recovery tank 5 mounted above the rodless cylinder. The feeding platform 1 is disposed inside the ink recovery tank 5. The bottom of the ink recovery tank 5 also has guide plates that extend vertically and vertically on opposite sides of the feeding platform 1 to guide and collect the small amount of ink flowing out from the feeding platform 1. Here, the recovery of the small amount of ink flowing out is achieved.

[0047] In summary, by adopting this ink supply device, the ink tank is placed against the upper surface of the supply platform from the bottom ink discharge port, and ink is added to the ink tank. A sealing component forms a circumferential sealing barrier area around the ink discharge port on the upper surface of the supply platform to prevent ink leakage. Then, the driver drives the ink tank and sealing component to move synchronously towards the ink-adhesion station. When the bottom ink discharge port of the ink tank is aligned and connected with the ink supply groove of the ink-adhesion station, ink automatically fills the ink supply groove forming the marking pattern from top to bottom. Next, the driver drives the ink tank and sealing component to move synchronously away from the ink-adhesion station to open the ink supply groove. At this point, only ink is present in the ink supply groove, allowing the marking head to accurately adhere to the ink for marking. Therefore, compared with existing technologies, this invention... The new design features four key improvements. First, a sealing component maintains a circumferential seal around the ink discharge port, allowing for precise ink filling by aligning the discharge port and ink supply tank as the ink tank moves. This effectively controls ink consumption and saves costs. Simultaneously, it significantly reduces ink residue in non-patterned areas of the feeding platform, improving marking quality and flexibly adapting to various continuous or discontinuous markings. Second, a counterweight ensures a tight fit between the sealing ring and the feeding platform, preventing loosening and ink leakage during movement. Third, it ensures smooth movement, preventing ink spillage due to shaking or accidental tipping of the ink tank, thus improving reliability. Fourth, an ink recovery tank allows for the recovery of any small amount of spilled ink.

[0048] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
