Description

Technical Field

[0001] This application relates to the field of disc pump technology, and in particular to a disc pump structure with pressure dividing function. Background Technology

[0002] Currently, disc pumps, also known as disc-shaped pressure plate piston pumps, are devices specifically designed for conveying high-viscosity, semi-solid, or particulate materials. Their core component is a disc-shaped pressure plate (piston) that fits tightly against the inner wall of the cylinder. Through reciprocating motion, pressure is generated, forcing the material out of the cylinder. The pressure plate can be designed with through holes or valves to control unidirectional flow.

[0003] A Chinese patent with publication number CN2726730Y discloses a three-component glue applicator package, including an A-component air pump, B and C-component air pumps, a lift, a high-pressure plunger pump, an electrical control box, a glue gun, and a base. The glue is preheated by a temperature-controlled heating platen and enters the high-pressure plunger pump through a high-pressure feed pipe. The feeding ratio of components A, B, and C is continuously adjusted between 6:1:1 and 14:1:1 by a ratio adjustment mechanism. The ratio is monitored by an online ratio controller and a mismatch alarm device. The pressurized glue is continuously and evenly fed into a three-component mixer through the high-pressure feed pipe for stirring. The mixed glue is then fed into a single-tube mixer through the glue gun for further homogenization and then filled or coated onto the workpiece through a nozzle.

[0004] In related technologies, a pressure plate is pressed into a material cylinder. As the pressure inside the cylinder increases, the material inside the cylinder is pressed out through the material holes on the pressure plate.

[0005] Regarding the aforementioned technologies, the inventors believe that if the pipeline becomes blocked, the pipeline pressure increases as the pressure plate is pressed in, which can easily lead to pipeline rupture and material ejection. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a disc pump structure with pressure dividing function, which solves the technical problem that if the pipeline is blocked, the pipeline pressure increases as the pressure disc is pressed in, which can easily cause the pipeline to rupture and result in material ejection.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A disc pump structure with pressure-distributing function includes: a frame for supporting the disc pump structure; a material cylinder mounted on the frame, with material placed inside the material cylinder; a lifting assembly mounted on the frame, with a pressure plate installed on the lifting assembly, the pressure plate pressing into the material cylinder; and a pressure-distributing assembly mounted on one side of the pressure plate, for distributing pressure in the material cylinder.

[0009] Furthermore, the lifting assembly includes a lifting plate and a lifting cylinder. The lifting cylinder is vertically mounted on the frame, one end of the piston rod of the lifting cylinder is connected to the lifting plate, and the pressure plate is mounted on one side of the lifting plate.

[0010] Furthermore, a pressure cover is provided on one side of the pressure plate, and a pressure cavity is formed between the pressure cover and the pressure plate. A connecting bolt is provided on the pressure plate, and one end of the connecting bolt passes through the pressure plate and is connected to the pressure cover. A discharge pipe is provided on the pressure cover, and the discharge pipe is connected to the pressure cavity.

[0011] Furthermore, the pressure plate is provided with through holes, and several through holes are spaced apart on the pressure plate. All of the through holes are connected to the pressure cavity, and a sealing ring is provided between the pressure plate and the pressure cover. The sealing ring is pressed against the pressure cover and the pressure plate.

[0012] Furthermore, the pressure dividing assembly includes a pressure dividing block with a pressure dividing hole that communicates with the pressure chamber. A storage pipe is provided on one side of the pressure dividing block, corresponding to the pressure dividing block. A connecting pipe is provided between the storage pipe and the pressure dividing block, connecting the connecting pipe to the storage pipe and its corresponding pressure dividing block. A pressure dividing pipe is provided on the connecting pipe and connected to the storage pipe.

[0013] Furthermore, a supporting inclined surface is formed on the inner side of the pressure dividing block, a ball core is embedded in the pressure dividing hole, a support rod is provided on the pressure dividing block, one end of the support rod is connected to the pressure dividing block, and the other end extends towards the side close to the ball core. A sealing ring is installed on the side of the pressure dividing block near the supporting inclined surface.

[0014] Furthermore, a feeding cylinder is installed on the lifting plate, one end of the piston rod of the feeding cylinder is inserted into the storage tube, and a plunger is installed on one end of the piston rod of the feeding cylinder, the plunger sliding inside the storage tube.

[0015] In summary, this application includes at least one of the following beneficial technical effects of a disc pump structure with pressure-sharing function:

[0016] The lifting assembly drives the pressure plate to move on the frame. As the pressure plate presses into the material cylinder, the material inside the cylinder is pressed out. When the pipe is blocked, the pressure-dividing assembly divides the pressure inside the material cylinder, allowing the material to be discharged normally. The operator does not need to stop the machine to clean the pipe, and the pipe is not easy to break.

[0017] The lifting plate and lifting cylinder, as well as the through holes on the pressure plate, make it easier to discharge materials from the barrel.

[0018] The connection between the pressure divider block, the storage pipe, and the feeding cylinder via connecting pipes improves the ease of material delivery. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a disc pump structure with pressure dividing function.

[0027] Reference Figures 1-2 A disc pump structure with pressure-dividing function includes a frame 1, on which a material cylinder 11 is mounted, and material is placed inside the material cylinder 11. A lifting assembly 2 and a pressure plate 3 are mounted on the frame 1. The lifting assembly 2 drives the pressure plate 3 to move up and down on the material cylinder 11. As the pressure plate 3 moves, the material inside the material cylinder 11 is pressed out. A pressure-dividing assembly 4 is also mounted on the frame 1 to divide the pressure inside the material cylinder 11.

[0028] Reference Figure 1The lifting assembly 2 includes a lifting cylinder 21 and a lifting plate 22. Two sets of lifting cylinders 21 are spaced apart on both sides of the material cylinder 11, and the two sets of lifting cylinders 21 are vertically arranged. The lifting plate 22 is located between the two sets of lifting cylinders 21. The lifting plate 22 is rectangular in shape, and its two ends in the length direction are respectively connected to the piston rods of the two sets of lifting cylinders 21. In use, the lifting cylinders 21 drive the lifting plate 22 to lift and lower on the frame 1.

[0029] Reference Figures 2-3 A pressure plate 3 is provided with a pressure cover 31, and a pressure cavity 32 is formed between the pressure plate 3 and the pressure cover 31. A number of connecting bolts 33 are provided on the pressure plate 3 at intervals, with one end of each bolt passing through the pressure plate 3 and threadedly connected to the pressure cover 31. Furthermore, a sealing ring 34 is provided between the pressure plate 3 and the pressure cover 31, abutting against the pressure plate 3 and sealing the gap between them, reducing the leakage of material from the pressure cavity 32 through the gap between the pressure plate 3 and the pressure cover 31.

[0030] The pressure plate 3 has several through holes spaced apart, all of which communicate with the pressure chamber 32. During use, as the pressure plate 3 is pressed into the material cylinder 11, the material in the material cylinder 11 is forced into the pressure chamber 32 through the through holes. Furthermore, a discharge pipe 36 is installed on the pressure cover 31, which communicates with the pressure chamber 32. During use, an external pipeline is connected to the discharge pipe 36. As the pressure plate 3 is pressed in, the material in the material cylinder 11 enters the pressure chamber 32, and then the material in the pressure chamber 32 is conveyed to the outside through the discharge pipe 36.

[0031] Reference Figures 3-4 When the external pipeline becomes blocked, the pressure inside the cylinder 11 will also increase. As the pressure plate 3 continues to press down, the pressure inside the cylinder 11 increases. In order to reduce the pressure acting on the external pipeline, the pipeline will rupture. The pressure dividing assembly 4 includes a pressure dividing block 41, which is installed on the pressure cover 31. The pressure dividing block 41 has pressure dividing holes 42. Two sets of pressure dividing holes 42 are spaced apart on the pressure dividing block 41, and both sets of pressure dividing holes 42 are connected to the pressure chamber 32.

[0032] A storage pipe 43 is provided on one side of the lifting plate 22. Two sets of storage pipes 43 are spaced apart. A connecting pipe 44 is provided between the two sets of storage pipes 43 and the pressure dividing block 41. One end of each connecting pipe 44 is connected to the pressure dividing hole 42 on the pressure dividing block 41, and the other end is connected to the corresponding storage pipe 43. Furthermore, each set of storage pipes 43 is provided with a pressure dividing pipe 45, which is connected to the storage pipe 43. When the discharge pipe 36 is blocked, the pressure dividing pipe 45 is opened. As the pressure dividing pipe 45 is opened, the material flows through the pressure dividing hole 42 on the pressure dividing block 41, through the connecting pipe 44, into the storage pipe 43, and then flows out from the pressure dividing pipe 45 through the storage pipe 43. In use, the pressure dividing pipe 45 is connected to an external pipeline, so that when the discharge pipe 36 is blocked, the pressure dividing pipe 45 can play a pressure dividing role. In addition, it can continuously supply material to the outside, improving working efficiency.

[0033] To improve the efficiency of material discharge from the storage pipe 43, a supporting inclined surface 46 is formed inside the pressure dividing block 41, and a ball core 47 is provided on the inner side of the pressure dividing block 41 near the supporting inclined surface 46. A support rod 48 is provided on the side of the pressure dividing block 41 opposite to the ball core 47. One end of the support rod 48 is connected to the pressure dividing block 41, and the other end extends towards the side near the ball core 47. In use, the support rod 48 supports the ball core 47. Furthermore, a sealing ring 461 is installed on the side of the pressure dividing block 41 near the supporting inclined surface 46.

[0034] A feeding cylinder 49 is installed on the lifting plate 22. One end of the piston rod of the feeding cylinder 49 is inserted into the storage pipe 43, and a plunger 491 is installed at the end of the piston rod of the feeding cylinder 49 inserted into the storage pipe 43. The feeding cylinder 49 drives the plunger 491 to slide in the storage pipe 43. When the plunger 491 slides to the side closer to the connecting pipe 44, the plunger 491 pushes the material out of the storage pipe 43. During the process of pushing the material out, some of the material presses the ball core 47 against the sealing ring 461 of the pressure dividing block 41, thereby reducing the material from flowing back from the pressure dividing block 41 into the material cylinder 11.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
