Description

Technical Field

[0001] This application relates to the field of disc pump technology, and in particular to an easy-to-use disc pump device. 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 material cylinder containing material is placed under a pressure plate, and then the pressure plate is pressed into the material cylinder. As the pressure inside the material cylinder increases, the material inside the material cylinder is pressed out through the material hole on the pressure plate.

[0005] Regarding the aforementioned technologies, the inventors believe that when a material-containing cylinder is placed below a pressure plate, the position of the cylinder needs to be adjusted so that the pressure plate can press into the cylinder. The material-containing cylinder is relatively heavy, making it difficult to adjust, which in turn affects the material conveying. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an easy-to-use disc pump device, which solves the technical problem that the material cylinder is placed under the pressure plate, and the position of the material cylinder needs to be adjusted so that the pressure plate can be pressed into the material cylinder. The material cylinder containing the material is heavy, and it is difficult to adjust the material cylinder, which affects the material conveying.

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

[0008] An easy-to-use disc pump device includes: a frame for supporting the disc pump device; a pressure plate assembly mounted on one side of the frame for compressing material in a cylinder; a lifting assembly mounted on the frame for driving the pressure plate assembly to move up and down on the frame; a tray mounted on the frame for placing the cylinder on the tray; and a positioning assembly mounted on the tray for positioning the cylinder.

A discharge pipe is provided on the pressure cover, and the discharge pipe is connected to the pressure cavity.

[0010] Furthermore, a support ring is formed on the pressure plate, a rubber ring is provided on the support ring, and a connecting bolt is provided on the support ring.

[0011] Furthermore, the lifting assembly includes a lifting cylinder and a lifting plate. The lifting cylinder is vertically mounted on the frame. The lifting plate is connected to the piston rod of the lifting cylinder. A connecting rod is provided on the lifting plate. One end of the connecting rod is connected to the lifting plate, and the other end is connected to the pressure cap.

[0012] Furthermore, a number of support wheels are rotatably mounted on the frame, and the support wheels are spaced apart on the frame to support the tray.

[0013] Furthermore, the positioning component includes a positioning seat, on which a positioning rod is provided. The positioning rod is rotatably mounted on the positioning seat.

Detailed Implementation

[0023] 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.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses an easy-to-use disc pump device.

[0026] Reference Figure 1A user-friendly disc pump device includes a frame 1, on which a pressure plate assembly 2 and a lifting assembly 3 are mounted. The lifting assembly 3 drives the pressure plate assembly 2 to rise and fall on the frame 1, pressing the pressure plate assembly 2 into a material cylinder. A tray 11 is mounted on the frame 1, and a positioning assembly 4 is mounted on the tray 11 to position the material tray.

[0027] Reference Figure 2 The pressure plate assembly 2 includes a pressure plate 21 and a pressure cover 22, forming a pressure cavity 23 between the pressure plate 21 and the pressure cover 22. A sealing ring 24 is provided between the pressure plate 21 and the pressure cover 22, and the sealing ring 24 abuts against the pressure plate 21 and the pressure cover 22 to seal the gap between them. The pressure plate 21 and the pressure cover 22 are locked together by bolts. Several pressure holes 211 are provided on the pressure plate 21, and each hole 211 communicates with the pressure cavity 23. A discharge pipe 221 is installed on the pressure cover 22, and the discharge pipe 221 communicates with the pressure cavity 23. In use, the pressure plate 21 is pressed into the material cylinder, the material enters the pressure cavity 23 through the pressure holes 211, and then the material is discharged through the discharge pipe 221.

[0028] To improve the sealing between the pressure plate 21 and the material cylinder, allowing the material to be pressed into the pressure chamber 23, a support ring 25 is formed on the pressure cover 22. The support ring 25 is annular in shape. Furthermore, a rubber ring 251 is provided on the support ring 25, which is fitted onto the pressure cover 22. Connecting bolts 252 are provided on the support ring 25, with several connecting bolts 252 spaced around the support ring 25. One end of each connecting bolt 252 passes through the support ring 25 and the rubber ring 251, and a nut 253 is threaded onto the end of the connecting bolt 252 that passes through the rubber ring 251. The nut 253 is pressed against the rubber ring 251.

[0029] Furthermore, a guide slope 254 is formed on the rubber ring 251, with the inclined direction of the guide slope 254 facing away from the pressure plate 21. When the pressure plate 21 is pressed into the material cylinder, the guide slope 254 on the rubber ring 251 guides the pressure plate 21, improving the ease of pressing the pressure plate 21 into the material cylinder. In addition, the rubber ring 251 abuts against the pressure cap 22 and the material cylinder, improving the sealing between the pressure cap 22 and the material cylinder. During use, if the rubber ring 251 wears, it can be replaced by rotating the nut 253.

[0030] To improve the ease of lifting and lowering the pressure plate 21 on the frame 1, the lifting assembly 3 includes a lifting cylinder 31 and a lifting plate 32. Two lifting cylinders 31 are spaced apart on both sides of the pressure plate, and the two cylinders 31 are vertically arranged. The lifting plate 32 is rectangular in shape, and both ends of the lifting plate 32 are connected to the piston rods of the two lifting cylinders 31. A connecting rod 33 is provided on the lifting plate 32, and the connecting rod 33 is vertically arranged, with one end connected to the lifting plate 32 and the other end connected to the pressure cover 22. In use, the lifting cylinders 31 drive the pressure plate 21 to rise and fall on the frame 1.

[0031] The tray 11 has a rectangular cross-section. Support wheels 34 are rotatably mounted on both sides of the frame 1 along the width direction of the tray 11. Several support wheels 34 are spaced apart on the frame 1, and the two sides of the tray 11 rest on the support wheels 34 along their width direction. In use, the tray 11 slides along its length on the support wheels 34. When the material cylinder is placed on the tray 11, it slides under the pressure plate 21 via the tray 11.

[0032] Reference Figure 3 The positioning component 4 is installed on the tray 11. When the tray 11 is directly below the pressure plate 21, the positioning component 4 is evenly spaced in three sets around the axis of the pressure plate 21. The three sets of positioning components 4 have the same structure and function. Only one set of positioning components 4 will be described below.

[0033] The positioning assembly 4 includes a positioning seat 41, which is mounted on the tray 11. A positioning rod 42 is mounted on the positioning seat 41. The positioning rod 42 is L-shaped, with its middle section rotatably mounted on the positioning seat 41. A positioning wheel 43 is rotatably mounted on one end of the positioning rod 42, and a support surface 44 is formed on the other end. In use, the material cylinder is placed on the support surface 44 of the positioning rod 42. Because the positioning rod 42 is rotatably mounted on the positioning seat 41, when the side of the positioning rod 42 closest to the support surface 44 is pressed down, the side of the positioning rod 42 closest to the positioning wheel 43 rotates towards the side closest to the material cylinder, thereby allowing the positioning wheel 43 to press against the material cylinder.

[0034] When the material cylinder needs to be replaced, it is lifted off the positioning rod 42. To improve the ease of lifting the material cylinder, a support spring 45 is provided between the positioning rod 42 and the positioning seat 41. The support spring 45 is pressed against the positioning seat 41 and the positioning rod 42. When the material cylinder is lifted, the support spring 45 pushes the positioning rod 42 up, allowing the positioning rod 42 to rotate away from the positioning seat 41. This improves the ease of placing and removing the material cylinder.

[0035] During the pressing process of the pressure plate 21 into the material cylinder, the pressure on the pressure plate 21 will act on the material cylinder. After long-term use, the middle of the tray 11 will be dented, which will affect the support effect of the tray 11 on the material cylinder.

[0036] Therefore, a support cylinder 12 and a support plate 13 are provided on the frame 1. The support cylinder 12 is vertically installed on the side of the frame 1 near the pallet 11, and the piston rod of the support cylinder 12 faces the side near the pallet 11. The support plate 13 is installed on the piston rod of the support cylinder 12. When the pressure of the pressure plate 21 is applied to the barrel, the support plate 13 of the support cylinder 12 is lifted up, and the support plate 13 supports the pallet 11 and the barrel, thereby improving the stability of the barrel on the pallet 11 and reducing the deformation of the pallet 11 during processing.

[0037] 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.
