DETAILED DESCRIPTION

[0027] With reference to the drawings of the embodiments of the utility model, the technical scheme in the embodiments of the utility model will be clearly and completely described, apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range of protection of the utility model.

[0028] Please refer to Figures 1 to 4 The utility model provides a technical scheme:

[0029] A screw passes gasket mechanism for diaphragm pump assembly, including workbench 1, the upper end of workbench 1 is provided with assembly body 2 and feeding vibration machine cylinder 21, feeding vibration machine cylinder 21 is located the left of assembly body 2, the outside fixed connection of feeding vibration machine cylinder 21 is provided with fixed block 22, the one end fixed connection of fixed block 22 is close to assembly body 2 is provided with transport block 23, the inside of transport block 23 is provided with transport groove 231, the inside and outside of transport block 23 is provided with material increasing assembly 3 in common, material increasing assembly 3 includes the cylinder 31 of fixed connection in transport block 23 front end, the front end of cylinder 31 is provided with first recess 311 with second recess 312, first recess 311 with second recess 312 is vertically distributed, the inside movable connection of cylinder 31 is provided with first round bar 32, the outside fixed connection of first round bar 32 is provided with pull rod 321 with second round bar 322, pull rod 321 is located second round bar 322 front, the rear end movable connection of first round bar 32 is provided with backboard 33;

[0030] The number of cylinder 31, first recess 311 and second recess 312 is two, the outside rear end of two cylinder 31 is movably connected with spring 323, the width of transport groove 231 is greater than the width of two gaskets, the thickness of backboard 33 is same with the thickness of gasket, the depth of first recess 311 is greater than the upper end of second recess 312, the spring force of spring 323 is greater than the gravity of backboard 33, backboard 33 is slidably attached to the inside of transport groove 231.

[0031] Through the above technical scheme, before the screw is threaded through the gasket, the gasket is first placed in the feeding vibration cylinder 21 at the upper end of the workbench 1, and then the assembly body 2 and the feeding vibration cylinder 21 are started. The feeding vibration cylinder 21 mainly includes a hopper, a chassis, a controller and a pulse electromagnet. When the electromagnet is powered on, a magnetic field is generated, which causes the hopper to produce a slight vibration in the vertical direction. This vibration is fast and frequent, thereby forming a continuous vibration effect. With the continuous vibration, the gasket moves upward along the hopper until it enters the first guide groove 221 in the fixed block 22. The gasket in the first guide groove 221 is affected by gravity and vibration and enters the feeding groove 231 in the conveying block 23. Finally, the gasket is transported to the assembly body 2 through the feeding groove 231 and then assembled. When two gaskets need to be threaded through the screw, the first circular rod 32 is moved forward by pulling the pull rod 321 outside the first circular rod 32. The first circular rod 32 in the cylinder 31 moves forward with the second circular rod 322 outside, the second circular rod 322 in the first recess 311 and the rear end of the back plate 33 move forward together. Then, by rotating the pull rod 321, the pull rod 321 rotates with the second circular rod 322 outside and is placed in the second recess 312. The back plate 33 compresses the spring 323, so that the gap between the back plate 33 and the feeding groove 231 can pass through two gaskets. At this time, the two gaskets in the feeding groove 231 stop when they contact the assembly body 2. After reaching the specified position, the positioning and installation work is carried out. When the spacer pump is further installed and fixed and sealed by the feeding assembly 3, a single screw is threaded through multiple gaskets, thereby providing better sealing effect, effectively preventing liquid leakage, thereby prolonging the service life of the diaphragm pump and reducing maintenance cost.

[0032] Specifically, as shown in Figure 4 The upper end of the back plate 33 is provided with a distribution assembly 4. The distribution assembly 4 includes a guide block 41 fixedly connected to the upper end of the back plate 33. The rear end of the guide block 41 is fixedly connected with a backing plate 42. The upper end of the backing plate 42 is fixedly connected with a distribution piece 43. The inside of the fixed block 22 is provided with a first guide groove 221. The front end of the first guide groove 221 is provided with a second guide groove 44. The upper end of the guide block 41 and the backing plate 42 are inclined. The guide block 41 and the backing plate 42 are slidingly attached to the inside of the second guide groove 44. The height of the second guide groove 44 is greater than the height of the first guide groove 221. The first guide groove 221 and the second guide groove 44 are connected with the feeding groove 231.

[0033] By adopting the above technical scheme, when the device needs to be reassembled one by one after the through gasket is adjusted by the feeding assembly 3, the inside of the feeding groove 231 is adjusted to pass through only one gasket by the feeding assembly 3, and the upper end guide block 41 returns together with the adjustment of the feeding assembly 3, and when the first guide groove 221 and the space inside the second guide groove 44 enter the two gaskets in coincidence, the gasket on one side moves along the gasket plate 42 under the vibration of the feeding vibration cylinder 21 when contacting the inclined slope on the guide block 41, and separates the two gaskets again when passing through the feeding piece 43, and the gasket close to the first guide groove 221 normally enters the inside of the feeding groove 231, so that the feeding assembly 4 separates the overlapped gaskets when the gaskets are overlapped, thereby avoiding that the gaskets are stuck in the device and affect the screw through gasket work, and further ensuring the normal operation of the equipment and improving the production efficiency.

[0034] Working principle: when two gaskets need to be threaded through the screw, the first circular rod 32 is moved forward by pulling the pull rod 321 outside the first circular rod 32, the first circular rod 32 in the cylinder 31 moves forward with the second circular rod 322 outside, the second circular rod 322 in the first groove 311 moves forward together with the back plate 33 at the rear end, and then the pull rod 321 is rotated, the pull rod 321 is rotated with the second circular rod 322 outside, and then placed in the second groove 312, the back plate 33 compresses the spring 323, so that the gap between the back plate 33 and the feeding groove 231 can pass through two gaskets, and the two end gaskets entering the inside of the feeding groove 231 stop when contacting the assembly body 2, and are positioned and installed after reaching the specified position, so that the feeding assembly 3 further installs and fixes and seals the diaphragm pump, and the single screw passes through multiple gaskets, thereby providing better sealing effect, effectively preventing liquid leakage, and further prolonging the service life of the diaphragm pump and reducing the maintenance cost.

[0035] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
