[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] At present, the osmotic membranes of rolled water purification filters are all manufactured using assembly line technology. During the assembly line production process of the osmotic membrane, the membrane needs to be continuously transported forward. The current practice is to use a reciprocating slide to drive the gripper to pull the membrane out, and cut it after pulling it out a specified distance. The reciprocating slide releases the gripper to release the membrane, and the empty gripper returns to the initial position for the next membrane pulling. Therefore, intermittent feeding is actually adopted. Intermittent feeding has an intermittent time, which is the time for the empty gripper to return to the initial position. The production line is stopped during this time, which is a waste of time. In addition, other processes on the production line also need to be adjusted according to the rhythm of intermittent feeding, and the entire production rhythm is slower.

[0017] Therefore, the present invention aims to solve the problem that the intermittent conveying of membranes by using reciprocating slide rails to drive grippers in the existing membrane production line during the membrane conveying process wastes time and prolongs the production cycle of the entire filter element. Figure 1-2 As shown, the following technical scheme is provided: a diaphragm vacuum conveying device of a rolled water purification filter element, comprising a negative pressure cavity 9, side support plates 3 are installed on the front and rear sides of the negative pressure cavity 9, and a driving shaft 13 and a driven shaft 12 are respectively installed between the side support plates 3 at both ends of the negative pressure cavity 9, and a driving assembly is installed at one end of the driving shaft 13, and a porous vacuum conveyor belt 1 passing horizontally from the upper side of the negative pressure cavity 9 is wound between the driving shaft 13 and the driven shaft 12, and an air inlet structure matching the porous vacuum conveyor belt 1 is arranged on the upper side of the negative pressure cavity 9, and a negative pressure fan interface 8 is also provided on the negative pressure cavity 9. By setting the negative pressure cavity 9, a continuous negative pressure can be generated when the porous vacuum conveyor belt 1 passes through the upper side of the negative pressure cavity 9, and the diaphragm on the upper side of the porous vacuum conveyor belt 1 is sucked and conveyed as the porous vacuum conveyor belt 1 moves, so that the conveying of the diaphragm in the entire production line will not stop, thereby improving the production rhythm.

[0018] Specifically, the diaphragm vacuum conveying device in this embodiment can be installed at the position where the diaphragm is loaded on the production line, cooperated with the cutting device, or laid end to end at the lower part of the production line. The diaphragm is continuously transported forward along multiple diaphragm vacuum conveying devices, and the negative pressure cavity 9 is configured as a flat cavity. The air inlet structure at the upper end can be configured as a mesh structure, which can cover the entire porous vacuum conveyor belt 1. The porous vacuum conveyor belt 1 is evenly distributed with porous holes. After the negative pressure cavity 9 is connected to the fan through the negative pressure fan interface 8, the air on the upper side of the air inlet structure can be continuously sucked into the negative pressure cavity 9, and negative pressure suction is generated through the evenly distributed holes on the porous vacuum conveyor belt 1, so that the diaphragm is firmly adsorbed on the porous vacuum conveyor belt 1.

A vertical tension adjustment plate 7 with a vertically adjustable position is installed at the lower end of the side support plate 3, and the guide shaft 14 is installed between the two vertical tension adjustment plates 7. By adjusting the positions of the horizontal tension adjustment plate 2 and the vertical tension adjustment plate 7, the tension of the porous vacuum conveyor belt 1 during the cyclic movement can be adjusted. The positions of the horizontal tension adjustment plate 2 and the vertical tension adjustment plate 7 can be adjusted by the cooperation of screws and slide grooves.

The second mounting plate 16, the first mounting plate 15 and the connecting plate 17 facilitate the installation of the entire diaphragm conveying device on the production line, and also facilitate multiple diaphragm conveying devices to be connected in sequence to realize continuous conveying of the diaphragm. The second mounting plate 16 and the lower part of the first mounting plate 15 are provided with mounting slots, which can be installed on the production line by fasteners. At the same time, the connecting plate 17 can connect adjacent diaphragm vacuum conveying devices together for easy installation.
