Description

Technical Field

[0001] This utility model relates to the technical field of dispensing control devices, specifically to a dispensing stop device. Background Technology

[0002] A dispensing machine is an industrial device that uses automated control to precisely and evenly apply fluid materials such as adhesives, paints, and inks to designated locations on a product. It effectively replaces the inconsistencies that easily occur with manual operation and is one of the key pieces of equipment for achieving automated production in modern manufacturing. It is widely used in electronics, automotive, medical device, and LED manufacturing industries. In dispensing operations, many types of adhesives have extremely strong curing properties. Not only do they quickly set after application, but they are also prone to curing when idle due to contact with air, temperature changes, and other factors. Furthermore, the residue after curing is extremely difficult to clean.

[0003] When existing dispensing control valve bodies are not used for several days, the adhesive residue inside the valve body gradually hardens, forming hard lumps or films that firmly adhere to the inner wall of the valve body, valve core, flow channels, and other critical parts, making them difficult to completely remove. This can also clog internal flow channels and wear down the valve core sealing structure, causing the entire valve body to lose its function and become unusable, increasing equipment maintenance costs and consumable consumption, and seriously affecting production progress. Utility Model Content

[0004] The purpose of this utility model is to provide a dispensing and stopping device to solve the above problems.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-6 As shown, in one embodiment, a dispensing and stopping device includes: a dispensing cylinder 1, a control valve 3, and a pressure tube device 4.

[0031] The dispensing tube 1 is mounted on a fixing part 2 made of sheet metal. The fixing part 2 is a support base formed by sheet metal processing that fits the shape of the dispensing tube 1, so that the dispensing tube 1 can be fixed on the dispensing machine by the fixing part 2. The two ends of the dispensing tube 1 are connected to the air supply end and the control valve 3 respectively through pipelines for conveying glue.

[0032] For example, one end of the dispensing cylinder 1 is provided with an air supply port for connecting to the air supply end, ensuring that the gas does not leak during transmission. The gas is then supplied through the air supply end to control the glue to flow out of the dispensing cylinder 1 at a preset flow rate and speed. Correspondingly, the other end of the dispensing cylinder 1 is connected to the dispensing tube 5 through a Luer connector, ensuring the sealing and reliability of the connection and effectively preventing glue leakage during transmission. The other end of the dispensing tube 5 is also connected to the dispensing needle through a Luer connector, so that the glue is accurately applied to the preset dispensing position on the product through the dispensing needle, ensuring the accuracy and quality of dispensing.

[0033] Please continue reading. Figures 1-6 In this embodiment, the control valve 3 includes a first valve body 31 and a second valve body 32, and the first valve body 31 and the second valve body 32 together form a pressure cavity.

[0034] It should be noted in detail that a pressing device 4 is installed inside the pressing cavity, and the pressing device 4 includes a pressing block 41 and a first elastic element 42, which is used to control the opening and closing of the dispensing tube 5.

[0035] For example, a push rod 33 that can move axially along the first valve body 31 is installed inside the first valve body 31, and a second elastic element 34 (such as a spring) is sleeved on the outside of the push rod 33. One end of the second elastic element 34 abuts against the inner wall step of the first valve body 31, and the other end contacts the flange on the push rod 33. An air pipe interface 35 is installed at one end of the first valve body 31, and the air pipe interface 35 is connected to the air supply end through a pipeline, so that compressed air can be supplied to the air pipe interface 35 through the air supply end, thereby driving the second elastic element 34 to drive the push rod 33 to extend out of the first valve body 31. When the compressed air is supplied, the thrust disappears, and the second elastic element 34 returns to its original shape under the action of its own elasticity, so that the push rod 33 retracts back into the first valve body 31.

[0036] Correspondingly, the other end of the first valve body 31 is provided with a first threaded part 311, so that the first valve body 31 can be threadedly connected to the second valve body 32 through the first threaded part 311. During rotation, the relative position of the two can be precisely adjusted, and the size of the internal pressing cavity can be adjusted. At the same time, the threaded connection method also facilitates disassembly and maintenance in the later stage.

[0037] Furthermore, a first mounting cavity 312 is provided inside the other end of the first valve body 31, and a set of coaxial first through holes 313 are symmetrically provided on both sides of the first mounting cavity 312, so that the dispensing tube 5 can pass through the first through holes 313 and pass through the first mounting cavity 312.

[0038] For example, a screw 36 is installed at the other end of the second valve body 32. One end of the screw 36 extends out of the second valve body 32 and is provided with a handle for easy rotation, while the other end extends into the interior of the second valve body 32. By rotating the screw 36 clockwise or counterclockwise, its extension length inside the second valve body 32 can be changed, and the preload force on the first elastic member 42 can be adjusted, thereby adjusting the pressure of the pressing block 41 on the dispensing tube 5: when the screw 36 is screwed inward, it will generate greater pressure on the first elastic member 42, thereby increasing the pressure of the pressing block 41 on the dispensing tube 5; when the screw 36 is screwed outward, the pressure on the first elastic member 42 decreases, thereby reducing the pressure of the pressing block 41 on the dispensing tube 5. This achieves precise adjustment of the pressure applied by the pressing block 41 to the dispensing tube 5, adapting to the on / off control requirements of dispensing tubes 5 of different specifications and materials.

[0039] Correspondingly, a second threaded portion 322 is provided inside one end of the second valve body 32, so that the second valve body 32 can be stably combined with the first valve body 31, and the relative position of the two can be finely adjusted by rotation during the connection process to ensure that the first mounting cavity 312 and the second mounting cavity 321 can be accurately docked to form a complete pressing cavity; a second mounting cavity 321 is correspondingly opened inside one end of the second valve body 32, so that the second mounting cavity 321 can be closed with the first mounting cavity 312 to form a pressing cavity.

[0040] Please continue reading. Figures 1-6 In this embodiment, the pressing block 41 includes a main body 411, and one end of the main body 411 is provided with a strip-shaped pressing part 412 to make the pressure distribution more uniform and avoid damage to the dispensing tube 5 due to excessive local pressure; while the middle part of the body is provided with an abutment part 413 to ensure that the elastic force of the first elastic member 42 can be uniformly transmitted to the pressing block 41; correspondingly, the first elastic member 42 abuts against the pressing block 41 and the second valve body 32 respectively. In the natural state, the first elastic member 42 will apply continuous pressure to the pressing block 41 to keep it in a state of squeezing the dispensing tube 5.

[0041] Working principle: When gas is introduced into the gas supply end, the push rod 33 is extended by the second elastic element 34, which in turn pushes the pressing block 41, causing the pressing block 41 to squeeze the first elastic element 42. At this time, the pressure on the dispensing tube 5 gradually decreases, allowing the glue in the dispensing tube 5 to flow out smoothly. When the gas supply end stops supplying gas, the second elastic element 34 and the push rod 33 return to their original positions, and the first elastic element 42 squeezes the pressing block 41 to squeeze the dispensing tube 5 again. At this time, the pressure on the dispensing tube 5 gradually increases, causing the glue in the dispensing tube 5 to stop flowing out.

[0042] Through the above technical solution, this application controls the pressure of the hose 5 by using the pressure device 4 installed inside the valve body of the control valve 3 in conjunction with the external air source connected to the valve body, thereby controlling whether the glue flows out. Since the valve body does not come into contact with the glue, the hose 5 can be directly replaced after the glue has cured, which solves the problem of valve body damage caused by glue curing, effectively improves production efficiency and reduces maintenance costs.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
