DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 The filter element pressing device with adaptive pressing force shown in the figure comprises a limiting frame 2 and a driver 1 installed on the inner wall of the right end of the limiting frame 2;

[0023] The left end outer wall of the driver 1 is connected to the push rod 5 near the upper and lower sides;

[0024] An extrusion plate 4 is fixedly connected between the left end outer walls of the two push rods 5;

[0025] A bottom plate 10 is provided on the left side of the extrusion plate 4, and pressure sensors 6 are embedded inside the outer wall of the left end of the extrusion plate 4 and near the upper and lower sides respectively to detect the pressure during extrusion. A fixed frame 11 is provided on the right side of the bottom plate 10, and a filter element a12 is provided on the right side of the fixed frame 11, and a filter element b13 is provided on the right side of the filter element a12. When the filter element assembly is extruded and assembled, the fixed frame 11, the filter element a12 and the filter element b13 are arranged from left to right on the right side of the bottom plate 10, and then the driver 1 is started, and the push rod 5 on the left side of the driver 1 will push the extrusion plate 4 to move from right to left, and push the filter element b13 and the filter element a12 to move into the fixed frame 11. During the extrusion process, the pressure sensor 6 on the left side of the extrusion plate 4 will detect the state between the fixed frame 11, the filter element a12 and the filter element b13, and provide feedback, so that the driver 1 automatically controls the pressure of the push rod 5 to avoid damage to the filter element assembly;

[0026] A limiting plate 9 is fixedly connected at the center of the front end outer wall of the bottom plate 10 to limit the position between the fixed frame 11, the filter element a12 and the filter element b13. A plurality of positioning heads 14 are arranged on the left side of the extrusion plate 4 to pre-determine the position of the filter element b13 for pre-extrusion operation. When the fixed frame 11, the filter element a12 and the filter element b13 are placed, they can be placed on the rear side of the limiting plate 9 to limit the position of the fixed frame 11, the filter element a12 and the filter element b13 to avoid misalignment during the extrusion process. At the same time, during the movement of the extrusion plate 4, the filter element b13 can be pre-pushed to move by the positioning head 14 to ensure that the correct positional relationship is maintained during the assembly and extrusion process.

[0027] like Figure 3 As shown, a positioning groove 16 opening to the left is provided inside the left end outer wall of the extrusion plate 4 to limit the position of the positioning head 14 that contracts after contacting the filter element b13, a slide groove 17 is provided on the right side of the positioning groove 16 and inside the extrusion plate 4, a slide rod 15 is fixedly connected to the right end outer wall of the positioning head 14 to perform lateral movement inside the slide groove 17 to limit the moving direction of the positioning head 14, and a baffle 19 is fixedly connected to the right end outer wall of the slide rod 15 to limit the maximum moving distance of the slide rod 15.

[0028] After the fixing frame 11, filter element a12 and filter element b13 are fitted together, the positioning head 14 will move to the inside of the positioning groove 16. At this time, the sliding rod 15 on the right side of the positioning head 14 will push the spring 18 to contract, so that the positioning head 14 and the outer wall of the left end of the extrusion plate 4 are in a flush state, avoiding the situation where the pressure sensor 6 cannot contact the surface of the filter element b13 to sense the pressure.

[0029] like Figure 2 and Figure 3 As shown, a spring 18 is fixedly connected between the right end outer wall of the baffle 19 and the right end inner wall of the slide groove 17. After contraction, the spring 18 drives the positioning head 14 to stay inside the positioning groove 16. A stopper is fixedly connected on the leftmost side between the upper and lower inner walls of the slide groove 17 to limit the movable distance of the baffle 19. The limit plate 9 is transparent.

[0030] After the filter element assembly is extruded and assembled, during the resetting process of the extrusion plate 4, the spring 18 will reset the positioning head 14, and will limit the position of the positioning head 14 through the restriction of the baffle 19 and the block to prevent the positioning head 14 from falling out. The transparent limiting plate 9 can intuitively observe the extrusion assembly process of the fixed frame 11, filter element a12 and filter element b13.

[0031] like Figure 1As shown, the front end outer wall of the driver 1 and near the upper and lower sides are respectively embedded with receivers 3 to receive the signal sent by the pressure sensor 6, the left end outer wall of the limiting frame 2 is fixedly connected with a fixed block 7, the left end inner wall of the limiting frame 2 is fixedly connected with a limiting block 8 to abut against the bottom plate 10 to limit the bending amplitude of the bottom plate 10, and the driver 1 is electrically connected to the external power supply.

[0032] After sensing the pressure value, the pressure sensor 6 will transmit the numerical signal to the receiver 3. After receiving the signal that the pressure value is too large, the driver 1 will reduce the pressure when the push rod 5 pushes the extrusion plate 4, and limit the position of the bottom plate 10 through the limit block 8 to avoid deformation of the bottom plate 10.

[0033] The implementation principle of this embodiment is as follows: when the filter element assembly is extruded and assembled, the fixed frame 11, the filter element a12 and the filter element b13 are arranged in sequence from left to right on the right side of the bottom plate 10, and then the driver 1 is started. The push rod 5 on the left side of the driver 1 will push the extrusion plate 4 to move from right to left, and push the filter element b13 and the filter element a12 to move inside the fixed frame 11. During the extrusion process, the pressure sensor 6 on the left side of the extrusion plate 4 will detect the state between the fixed frame 11, the filter element a12 and the filter element b13, and provide feedback, so that the driver 1 automatically controls the pressure of the push rod 5 to avoid damage to the filter element assembly. When the fixed frame 11, the filter element a12 and the filter element b13 are placed, they can be placed on the rear side of the limit plate 9 to limit the positions of the fixed frame 11, the filter element a12 and the filter element b13 to avoid misalignment during the extrusion process. At the same time, during the movement of the extrusion plate 4, the filter element b13 can be pushed to move in advance by the positioning head 14 to ensure that the correct positional relationship is maintained during the assembly and extrusion process.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
