Description

Technical Field

[0001] The utility model relates to the field of AB valve related products, in particular to an AB screw valve with a large flow rate and convenient adjustment. Background Art

[0002] When processing new energy-related workpieces, a large-flow AB screw valve is usually used to dispensing glue on the workpiece. The AB screw valve is a dispensing device that can mix two different glues and is very convenient and quick to use.

[0003] However, the existing AB screw valve still has some disadvantages when in use. For example, the two glues AB mixed in the mixing cylinder valve body cannot be squeezed out quickly and effectively due to the traditional method of manual pressing and squeezing, which not only consumes physical strength but also makes it impossible to evenly mix the squeezed AB glues. At the same time, after long-term use, the inner wall of the existing mixing cylinder valve body will be adsorbed on the inner wall of the mixing cylinder valve body due to the certain adsorption force of the glue itself. As a result, a large amount of glue will be adsorbed on the inner wall, which will affect the use of the entire device after a long time. Utility Model Content

[0004] The purpose of the present invention is to provide a large-flow AB screw valve that is easy to adjust, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-flow AB screw valve with convenient adjustment, comprising an A-type cylindrical valve body and a B-type cylindrical valve body, wherein the A-type cylindrical valve body and the B-type cylindrical valve body are fixedly connected via a connecting plate, a feed pipe is fixedly inserted at the top of each of the A-type cylindrical valve body and the B-type cylindrical valve body, a motor is fixedly connected to the top of each of the A-type cylindrical valve body and the B-type cylindrical valve body, a shaft is fixedly connected to the output end of the motor, the bottom end of the shaft passes through the A-type cylindrical valve body and the B-type cylindrical valve body and is fixedly connected to an extrusion screw, a discharge pipe is fixedly inserted at the bottom end of each of the A-type cylindrical valve body and the B-type cylindrical valve body, A flow control valve is provided on the discharge pipe, and a swing plate is sleeved on the shaft rod, and a through hole is provided on the swing plate corresponding to the shaft rod, and a clamp is provided in the through hole, and the clamp is provided on the outside of the shaft rod, and a connecting rotating groove is provided on one side of the through hole, and a threaded rod is rotatably connected in the rotating groove, and two moving blocks are threadedly sleeved on the threaded rod, and one end of the two moving blocks is fixedly connected to one end of the clamp, and one end of the threaded rod is fixedly connected to a rotating rod, and one end of the rotating rod passes through the swing plate and extends outward, and one end of the swing plate is fixedly connected to a mounting plate, and one side of the mounting plate is fixedly connected to a scraper.

[0006] Preferably, the thread rotation directions on both sides of the center point of the horizontal axial section of the threaded rod are opposite.

[0007] Preferably, the inner tops of the A cylindrical valve body and the B cylindrical valve body are both provided with T-slots, a T-block is slidably connected in the T-slot, and one end of the T-block is fixedly connected to the swing plate.

[0008] Preferably, a rotating block is fixedly connected to one end of the rotating rod extending outward.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This easily adjustable large-flow AB screw valve introduces glue through the feed pipe, and controls the starting motor to drive the shaft to rotate. At this time, the shaft prompts the extrusion screw to rotate and thus squeezes and discharges the glue. The discharge amount is accurately controlled by the flow control valve. When it is necessary to clean the inner walls of the A cylindrical valve body and the B cylindrical valve body, the rotating rod is rotated to drive the threaded rod to rotate. When the threaded rod rotates, the two moving blocks on which the thread is sleeved move relative to each other, thereby prompting the clamp to tighten. At this time, the clamp is fixedly sleeved on the shaft to achieve fixation between the shaft and the swing plate. When the shaft rotates, the swing plate drives the mounting plate to rotate with it, thereby prompting the scraper to rotate to scrape the material on the inner wall of the cylindrical valve body. The utility model facilitates the cleaning of the inner wall of the cylindrical valve body through the provision of the scraper assembly, thereby avoiding clogging of the cylindrical valve body.

Two moving blocks 12 are threadedly sleeved on the threaded rod 11, and one end of the two moving blocks 12 is fixedly connected to one end of the clamp 10. One end of the threaded rod 11 is fixedly connected to a rotating rod 13, and one end of the rotating rod 13 passes through the swing plate 9 and extends outward. One end of the swing plate 9 is fixedly connected to a mounting plate 14, and one side of the mounting plate 14 is fixedly connected to a scraper 15. Specifically, rotating the rotating rod 13 can drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, the two moving blocks 12 threadedly sleeved thereon move relative to each other, thereby prompting the clamp 10 to tighten. At this time, the clamp 10 is fixedly sleeved on the shaft rod 6 to achieve fixation between the shaft rod 6 and the swing plate 9. When the shaft rod 6 rotates, the swing plate 9 drives the mounting plate 14 to rotate, thereby prompting the scraper 15 to rotate to scrape the material on the inner wall of the cylindrical valve body.

When the inner walls of the A cylindrical valve body 1 and the B cylindrical valve body 2 need to be cleaned, the rotating rod 13 is rotated to drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, the two moving blocks 12 threaded on it move relative to each other, thereby prompting the clamp 10 to tighten. At this time, the clamp 10 is fixedly sleeved on the shaft 6 to realize the fixation between the shaft 6 and the swing plate 9. When the shaft 6 rotates, the swing plate 9 drives the mounting plate 14 to follow the rotation, thereby prompting the scraper 15 to rotate to scrape the material on the inner wall of the cylindrical valve body.
