Description

Technical Field

[0001] The utility model relates to the technical field of membrane cutting machines for reverse osmosis membrane production, in particular to a membrane grid cutting machine for reverse osmosis membrane production. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. The working principle of reverse osmosis membrane is to use chemical potential gradient and pressure difference to push water molecules to penetrate the membrane, while the tiny pores can prevent the passage of large molecules and large particles. In the production process of reverse osmosis membrane, the membrane needs to be cut into twice the size of the polypropylene net, and then the membrane is folded to cover the polypropylene net, and finally combined with a plastic roller and glue to make a reverse osmosis membrane element. Before use, the polyethylene net needs to be uniformly cut into membrane grids of the same size by a cutting machine before use.

[0003] Most of the existing membrane grid cutting machines are composed of two sets of conveying structures and a cutting platform. The cutting platform is arranged between the two sets of conveying structures. As a result, when the conveying structure is conveying the cut membrane grid, the membrane grid will bend downward in the cutting groove between the two sets of conveying structures because there is no support at the bottom, which makes it impossible to cut the subsequent mesh, affecting the cutting work. At the same time, due to the thin sheet structure of polypropylene of the membrane grid, the weight is relatively light, and it is easy to slip during the transportation process, causing the membrane grid to bulge on the conveyor belt, affecting the work. Therefore, we have proposed a membrane grid cutting machine for reverse osmosis membrane production to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a reverse osmosis membrane production membrane grid cutting machine to solve the problem raised by the above background technology that the reverse osmosis membrane production membrane grid cutting machine on the market currently has no support at the bottom, resulting in downward bending and easy slipping during transportation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a reverse osmosis membrane production membrane grid cutting machine, comprising a platform support, a first conveyor belt, a first rotating roller, a cutting support frame, a cutting mechanism and a second spring, wherein the first conveyor belt is arranged on the right side of the platform support, and the first conveyor belt is arranged on the first rotating roller, and the cutting support frame is arranged at the left end of the first conveyor belt, the cutting mechanism is arranged in the cutting support frame, and movable plates are connected on both sides of the cutting mechanism, first slide grooves are arranged on both sides of the cutting support frame, and a first slider is arranged in the bottom of the first slide groove, and a first spring is connected to the bottom of the first slider, a first connecting block is connected to the first slider, and the second rotating roller is connected to the first connecting block, a second conveyor belt is arranged on the left side of the first conveyor belt, and a support plate is arranged between the second conveyor belt and the first conveyor belt, and a movable block is arranged in the center of the support plate, a connecting plate is arranged at the bottom of the movable block, and a second spring is connected to the bottom of the connecting plate, and a fixed plate is arranged on the outside of the second spring.

[0006] Preferably, the movable plate forms a movable structure in the first sliding grooves on both sides of the cutting support frame through the extension blocks at the corners.

[0007] Preferably, the first sliding block is connected to the bottom of the first sliding groove on both sides of the cutting support frame through a first spring, and the first sliding block is movably connected to the first sliding groove.

[0008] Preferably, the second rotating roller forms a sliding groove movable structure with the first sliding grooves on both sides of the cutting support frame through the first sliding block.

[0009] Preferably, the movable block is arranged at the center of the support plate through a slide groove, and the movable block forms a reciprocating structure on the fixed plate through a connecting plate and a second spring.

[0010] Preferably, the surfaces of the first conveyor belt, the second conveyor belt and the second rotating roller are all provided with plastic needle plates.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the reverse osmosis membrane production membrane grid cutting machine:

[0012] (1) A reciprocating structure consisting of a movable block, a connecting plate, a fixed plate, and a second spring is arranged in the support plate at the bottom of the cutting blade, so that when the cutting blade is cutting, the movable block is pressed downward by the pressure of the blade, so that a gap is generated between the blade and the support plate, thereby completing the cutting. At the same time, when the blade is retracted, the second spring drives the connecting plate to reset the movable block upward, so that the movable block support plate and the first conveyor belt and the second conveyor belt on both sides are kept on the same plane, so that the diaphragm grid is supported to move after cutting, and will not move downward due to lack of support, causing machine failure. At the same time, when cutting, the first sliders on the rear sides of the second rotating rollers on both sides are pressed downward by the extension blocks of the movable plates on both sides of the cutting mechanism, so that the second rotating rollers also move downward, thereby squeezing and fixing the diaphragm grids on both sides;

[0013] (2) A first rotating roller is arranged on the right side of the first conveyor belt to squeeze the membrane grid placed on the first conveyor belt for cutting, so that the membrane grid can fit with the needle plate on the first conveyor belt, thereby preventing the membrane grid from slipping. At the same time, the second rotating roller that presses down the first slider through the movable plate during cutting will squeeze the membrane grid entering the second conveyor belt, thereby avoiding slipping during transportation. At the same time, a needle plate is also arranged on the second rotating roller, thereby facilitating the membrane grid to move stably on the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The movable plate 6 forms a movable structure in the first slide grooves 7 on both sides of the cutting support frame 4 through the extension blocks at the corners, so that the first slider 8 on the lower side can be squeezed through the extension blocks, so that the second rotating roller 11 squeezes and fixes the membrane grid downward.

[0023] The first slider 8 is connected to the bottom of the first slide groove 7 on both sides of the cutting support frame 4 through the first spring 9, so that the first slider 8 can be reset after being squeezed by the extension block of the movable plate 6 through the rebound force of the first spring 9, thereby maintaining a certain distance from the first conveyor belt 2 and the second conveyor belt 12 on the lower side, thereby facilitating the transportation of the membrane grid, and the first slider 8 is movably connected to the first slide groove 7, which facilitates the first slider 8 to move in the first slide groove 7 through the first spring 9.

[0024] The second rotating roller 11 forms a movable slide groove structure with the first slide grooves 7 on both sides of the cutting support frame 4 through the first slider 8, so that the second rotating roller 11 can move after being squeezed by the extension block of the movable plate 6 following the first slider 8, thereby squeezing and fixing the membrane grid or releasing the contact for transportation.

[0025] The movable block 14 is arranged at the center of the support plate 13 through a slide groove, and the movable block 14 forms a reciprocating structure on the fixed plate 16 through the connecting plate 15 and the second spring 17, so that the movable block 14 can reciprocate in the support plate 13 under the pressure of the cutting blade and the force of the second spring 17, and the movable block 14 is flush with the support plate 13 and the first conveyor belt 2 and the second conveyor belt 12 when not under pressure, so that the diaphragm grid will not be stuck due to the height difference.

[0026] Plastic needle plates are provided on the surfaces of the first conveyor belt 2 , the second conveyor belt 12 and the second rotating roller 11 , thereby reducing the problem of the membrane grid slipping on the first conveyor belt 2 and the second conveyor belt 12 .

[0027] Working principle: When using the reverse osmosis membrane production membrane grid cutting machine, first, place the membrane grid roll on the bracket on the right side of the first conveyor belt 2, then pull out one end of the membrane grid, pass it through the first rotating roller 3, and place it on the first conveyor belt 2, and then start the first conveyor belt 2, the second conveyor belt 12, the first rotating roller 3, and the second rotating roller 11. The motor and motor connected to the second rotating roller 11 make the first conveyor belt 2 drive the membrane grid to move forward, and at the same time, the first rotating roller 3 squeezes the membrane grid and stabilizes it on the needle plate on the first conveyor belt 2, and then the membrane grid is received by the second rotating roller 11, and driven to move into the cutting support frame 4, and then the membrane grid is pushed by the second rotating roller 11 and the first conveyor belt 2 to enter the plane composed of the support plate 13 and the movable block 14, and finally pushed into the second rotating roller 11 and the second conveyor belt 12 on the right side;

[0028] When it is necessary to reach the cutting distance, the first conveyor belt 2, the second conveyor belt 12, the first rotating roller 3, and the second rotating roller 11 stop rotating, and the cutting mechanism 5 is pressed down by the movable structure on the cutting support frame 4, and at the same time, the movable plates 6 on both sides of the cutting mechanism 5 and the extension blocks in the first slide grooves 7 on both sides of the cutting support frame 4 are also pressed down along the first slide grooves 7 to squeeze the first slider 8 at the bottom, and then the first slider 8 drives the second rotating roller 11 connected to the outside by the first connecting block 10 to move downward, thereby squeezing and fixing the membrane grids on both sides of the cutting support frame 4 to prevent movement during cutting, and when the cutting support frame 4 moves downward, the movable block 14 in the support plate 13 also moves downward due to the movement of the blade, so that the blade can cut the membrane grid;

[0029] After the cutting is completed, the cutting mechanism 5 moves upward, and the pressure on the first slider 8 and the movable block 14 disappears, so that the first slider 8 and the movable block 14 are reset by the first spring 9 and the second spring 17 at the bottom respectively. At the same time, the first conveyor belt 2, the second conveyor belt 12, the first rotating roller 3, and the second rotating roller 11 stop and start again, and the cut membrane grid is driven by the second conveyor belt 12 and the second rotating roller 11 on the upper side to be transported for the next operation, and the membrane grid on the rear side is pulled into the cutting support frame 4 again for further operation.
