Description

Technical Field

[0001] This utility model belongs to the field of marking equipment, specifically relating to a marking device for 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 Publication No. CN112976830A, discloses a hydraulic hose marking device, including 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 pressure roller and a marking roller to press the hydraulic hose, so that when the pressure roller rotates, it drives the hydraulic hose to deliver and drives the marking roller to rotate synchronously.

[0004] However, in actual production, the existing technology of using rubber hoses for simultaneous transmission and marking based on upper and lower extrusion pressure not only easily causes deformation or wear of the hoses, but also makes it impossible to guarantee positional accuracy during transmission, resulting in deviations in the marking position (e.g., tilting to one side due to feeding operation errors). Furthermore, because the surface of the hose is curved, the marking position with deviations cannot fully contact the ink, resulting in partially unclear marking patterns. In addition, marking is performed by the rolling contact between the marking wheel and the hose, which cannot achieve one-time forming of the marking pattern. 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 marking device for 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: A marking device for a rubber tube end includes a marking head with a marking end face formed from the bottom. The marking device also includes a positioning seat and a marking power unit. The positioning seat and the ink supply station are spaced apart. A positioning groove matching the rubber tube end is formed on the positioning seat. One end of the positioning groove forms a reference surface. The rubber tube end is positioned in the positioning groove with its end face abutting the reference surface, and the marking position of the rubber tube end faces upward. The marking power unit includes a base disposed between the positioning seat and the ink supply station, a rotating frame rotatably connected to the base, and a rotating power component that drives the rotating frame to rotate back and forth to form a first limit position and a second limit position. The marking head is mounted on the rotating frame. As the rotating frame rotates to the first limit position or the second limit position, the marking head keeps its marking end face downward and is aligned with the ink supply station or the marking position to pick up ink or mark.

[0007] According to a specific embodiment and preferred aspect of this utility model, the flipping frame includes a first and a second frame rod rotatably connected to a base from one end via a horizontal pivot, a third frame rod rotatably connected to the other end of the first and second frame rods, and a base mounted on the third frame rod and connected to the marking head. The first and second frame rods are parallel vertically but staggered axially along the pivot. This multi-frame arrangement stabilizes the flipping motion and improves the stability of the marking head's movement. Furthermore, the staggered arrangement of the first and second frame rods avoids mutual interference during rotation, resulting in a compact overall structure and space saving.

[0008] Preferably, the frame includes a first base body vertically connected to a third support rod, a second base body connected to the first base body and extending horizontally, and a marking head connected to the second base body. Here, by adjusting the height of the first base body, the ink intake and marking pressure of the marking head at its extreme positions can be adjusted to meet the needs of different processes.

[0009] Preferably, the second base has multiple first movable grooves arranged side-by-side at intervals and a second movable groove connecting the multiple first movable grooves. In the orthographic projection on the horizontal plane, the extending direction of each first movable groove intersects the length direction of the tube end, allowing the marking head to move and adjust along the first movable groove and / or the second movable groove. Here, the position of the marking head can be adjusted with high precision according to actual needs, further improving the accuracy of the marking or ink-taking position.

[0010] Preferably, in the orthographic projection on the horizontal plane, the first movable groove is perpendicular to the end of the hose.

[0011] Preferably, in the orthographic projection on the horizontal plane, the second movable groove is parallel to the end of the hose; and / or, the second movable groove intersects with the middle of each of the first movable grooves.

[0012] According to another specific embodiment and preferred aspect of the present invention, the marking head includes a marking module and a connecting component fixedly disposed on the top of the marking module, wherein the marking module is movably or fixedly connected to the first movable groove and / or the second movable groove through the connecting component.

[0013] Preferably, the marking module is tapered from top to bottom; and / or, the connecting components include a connecting module that is fitted and fixed to the top surface of the marking module, and bolted connectors that extend upward from the top of the connecting module and pass through the first movable slot and / or the second movable slot. This design is simple and easy to assemble and disassemble.

[0014] According to another specific embodiment and preferred aspect of this utility model, the positioning seat is recessed inward from the top surface to form a positioning groove, wherein one end of the positioning groove is open and the other end forms a reference surface. Here, the positioning is accurate and the operation is simple and convenient.

[0015] In addition, the positioning seat can be moved and adjusted along the length of the hose end.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: Existing technology uses a hose for simultaneous transmission and marking based on upper and lower extrusion pressure. This not only easily causes hose deformation or wear, but also makes it difficult to guarantee positional accuracy during transmission, leading to potential marking position deviations (e.g., tilting to one side due to feeding errors). Furthermore, because the hose surface is curved, the marking position at the deviation point cannot fully contact the ink, resulting in partially unclear marking patterns. In addition, marking is performed by the rolling contact between the marking wheel and the hose, which cannot achieve one-time marking. This application, however, redesigns the structure of the hose end marking device to cleverly solve the shortcomings and defects of the existing technology. With this hose end marking device, the hose end is placed in the positioning groove and its end face is aligned with the reference surface to achieve precise positioning, with the marking position of the hose end facing upwards. The marking head is installed on the flipping frame, and the flipping power component drives the flipping frame to flip to the first or second limit position. The marking head then keeps its marking end face downwards and aligns with the ink supply station or marking position to pick up ink or form a mark in one step. Therefore, compared with the prior art, this utility model, on the one hand, ensures that the end face of the tube is positioned in the positioning groove by fitting it against the reference surface, thus ensuring that the tube end maintains precise positional accuracy during the marking process; on the other hand, based on the back-and-forth flipping motion of the marking head with the marking end face facing down, the marking end face is precisely aligned with the ink supply station and the marking position at two extreme positions, effectively improving the ink picking or marking accuracy, realizing one-time forming of the marking pattern, and improving the forming effect of the marking pattern.

[0024] See Figures 1 to 3 As shown, the tube end marking device in this embodiment includes a marking head 1, a positioning seat 2, and a marking power unit 3.

[0025] Specifically, the marking head 1 includes a marking module 10 and a connecting component 11 fixedly disposed on the top of the marking module 10.

[0026] The marking module 10 gradually narrows from top to bottom, and it is a marking module used in any conventional marking machine. The marking module 10 forms a marking end face m1 from its bottom surface, which is composed of the marking pattern. During ink intake, the marking end face m1 of the marking module 10 contacts the ink supply station w. During marking, the marking end face m1 of the marking module 10 contacts the end of the rubber tube. The connecting component 11 includes a connecting module 110 that is attached and fixed to the top surface of the marking module 10, and a bolt connector 111 extending upward from the top of the connecting module 110. This design is simple and easy to assemble and disassemble.

[0027] In this example, the positioning seat 2 and the ink supply station w are distributed at intervals, and the positioning seat 2 has a reference surface m2. The end of the hose T is positioned on the positioning seat 2 with its end face in contact with the reference surface m2, and the marking position of the end of the hose T faces upward.

[0028] To facilitate implementation, the positioning seat 2 is recessed inward from the top surface to form a positioning groove 20 that matches the end of the hose. One end of the positioning groove 20 is open, and the other end forms a reference surface m2. In other words, during production, workers can quickly place the hose end on the positioning seat, and after marking, quickly remove the hose end and replace it with the next hose end, greatly improving the efficiency of loading and unloading, and the operation is simple and labor-saving.

[0029] Meanwhile, the positioning seat 2 can be moved and adjusted along the length direction (i.e., the front-to-back direction) of the hose end T.

[0030] In this example, the marking power unit 3 includes a base 30 disposed between the positioning seat 2 and the ink supply station w, a flipping frame 31 rotatably connected to the base 30, and a flipping power component that drives the flipping frame 31 to flip back and forth to form a first limit position and a second limit position. The marking head 1 is mounted on the flipping frame 31, and as the flipping frame 31 flips to the first limit position or the second limit position, the marking head 1 keeps the marking end face m1 facing down and is aligned with the ink supply station w or the marking position to pick up ink or mark.

[0031] In some specific embodiments, the flipping frame 31 includes a first support rod 311 and a second support rod 312 rotatably connected to the base from one end via a horizontal pivot s, a third support rod 313 rotatably connected to the other end of the first support rod 311 and the second support rod 312, and a base 314 disposed on the third support rod 313 and connected to the marking head 1. The first support rod 311 and the second support rod 312 are parallel vertically and staggered axially at the pivot s. During the flipping motion, the third support rod 313 remains vertical. This multi-support rod layout stabilizes the flipping motion and improves the stability of the marking head's movement. Furthermore, the staggered arrangement of the first and second support rods avoids mutual interference during rotation, resulting in a compact overall structure and space saving.

[0032] To further facilitate implementation, the frame 314 includes a first base a1 that is vertically movably connected to the third support rod 313, a second base a2 connected to the first base a1, and the marking head 1 connected to the second base a2. Here, by adjusting the height of the first base, the ink intake and marking pressure of the marking head at its extreme positions can be adjusted to meet the needs of different processes.

[0033] In some specific embodiments, the second seat a2 has a plurality of first movable grooves a21 arranged side by side at intervals, and a second movable groove a22 connecting the plurality of first movable grooves a21. In the orthographic projection on the horizontal plane, the extension direction of each first movable groove a21 intersects the length direction of the tube end T. The marking head 1 can move and adjust along the first movable groove a21 and / or the second movable groove a22. Here, the position of the marking head is adjusted with high precision according to actual needs, further improving the accuracy of the marking or ink picking position.

[0034] Meanwhile, in the orthographic projection on the horizontal plane, the first movable grooves a21 are perpendicular to the rubber tube end T, the second movable groove a22 is parallel to the rubber tube end T, and the second movable groove a22 intersects the middle part of each first movable groove a21. In this embodiment, there are three first movable grooves a21, and the three first movable grooves a21 and the second movable groove a22 form a "King" shape. The marking module 10 is movably connected or fixedly connected to the first movable grooves a21 and / or the second movable groove a22 via a connecting component 11, wherein the marking module 10 is located below the second seat a2, and the bolt connector 111 correspondingly passes through the first movable grooves a21 and / or the second movable groove a22 upward.

[0035] In conclusion, by adopting the rubber tube end marking device, the rubber tube end is placed in the positioning groove with its end face attached to the reference surface to form accurate positioning, and the marking position of the rubber tube end faces upward; the marking head is mounted on the turnover frame, and the turnover power member drives the turnover frame to turn over to the first limit position or the second limit position, and the marking head accordingly keeps its marking end face facing downward and aligns with the ink supply station or the marking position for ink taking or one-time forming of marking. Therefore, compared with the prior art, on one hand, the utility model positions the rubber tube end in the positioning groove by attaching the end face of the rubber tube end to the reference surface, ensuring the rubber tube end accurately maintains position precision during the marking process; on the other hand, based on the forward and backward turning movement of the marking head with the marking end face kept facing downward, the marking end face can be accurately aligned with the ink supply station and the marking position at two limit positions, effectively improving ink taking precision and marking precision, realizing one-time forming of the marking pattern, and improving the forming effect of the marking pattern; in the third aspect, a multi-frame rod layout is adopted, so that the turning movement is stable, and the motion stability of the marking head is improved. Meanwhile, based on the staggered layout of the first frame rod and the second frame rod, mutual interference during rotation is avoided, which is beneficial to compact overall structure and space saving; in the fourth aspect, by adjusting the height of the first seat body, the ink taking and marking pressure of the marking head at the limit position can be adjusted to meet the requirements of different processes, and meanwhile, the second seat body can be adjusted along the length direction of the rubber tube end to flexibly match different marking positions on the rubber tube end.

[0036] The utility model is described in detail above, with the purpose of enabling those skilled in the art to understand the content of the utility model and implement it, and cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model shall be covered within the protection scope of the utility model.
