Description

Technical Field

[0001] This utility model relates to the technical field of diaphragm production equipment, specifically to a double-layer diaphragm production equipment for diaphragm valves. Background Technology

[0002] A diaphragm valve is a special type of shut-off valve. The working principle of a diaphragm valve is to control the flow of fluid by the up-and-down movement of the diaphragm. The double-layer diaphragm is the core component of the diaphragm valve. With the widespread application of diaphragm valves in biopharmaceuticals, milk, beverages, steam production, and water distribution equipment that comes into contact with drinking water, the demand for double-layer diaphragms is also increasing.

[0003] Referring to the authorized patent application CN107914315A, a double-layer diaphragm production equipment for diaphragm valves is disclosed, including a double-layer diaphragm feeding device and a positioning drilling device for drilling holes in the processed double-layer diaphragms. The double-layer diaphragm feeding device includes a soft diaphragm feeding mechanism for conveying a soft diaphragm to the positioning drilling mechanism and a hard diaphragm feeding mechanism for conveying a hard diaphragm to the positioning drilling mechanism. The positioning drilling device includes a positioning fixture, a rotating mechanism for driving the positioning fixture to rotate intermittently, and a drilling mechanism disposed beside the rotating mechanism. The soft diaphragm feeding mechanism includes a first conveying component for conveying the soft diaphragm and a first flipping mechanism for flipping the soft diaphragm into the positioning fixture. The hard diaphragm feeding mechanism includes a second conveying component for conveying the hard diaphragm and a second flipping mechanism for flipping the hard diaphragm onto the soft diaphragm in the positioning fixture. This invention automatically feeds and assembles the soft and hard diaphragms, reduces processing steps, and improves production efficiency.

[0004] As shown in the prior art, the production of diaphragm valves in the prior art requires positioning and merging the soft and hard diaphragms and then punching holes on their outer edges one by one. However, the existing double-layer diaphragm production equipment transports the soft and hard diaphragms to the positioning fixture and waits for the holes to be punched one by one before unloading them. Only then can the next set of diaphragms be positioned again. During the gap between punching and unloading, the diaphragm loading work stops, resulting in relatively low production efficiency.

[0005] Therefore, it is necessary to provide a double-layer diaphragm production equipment for diaphragm valves to solve the above-mentioned technical problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides two technical solutions:

[0030] Figures 1 to 5The first embodiment is shown: a double-layer membrane production equipment for a diaphragm valve, including a base plate 1, with transport components 2 symmetrically arranged on both sides of the base plate 1. The two transport components 2 are used to transport a soft membrane and a hard membrane respectively. Each of the two transport components 2 is provided with a clamping component 3 on the side of the base plate 1 that clamps and flips the membrane to the side of the base plate 1.

[0031] Two symmetrically arranged mounting seats 4 are slidably connected above the base plate 1. The two mounting seats 4 are fixedly connected. Each of the two mounting seats 4 has a positioning diaphragm and a positioning component that rotates the diaphragm at the end near the transport component 2. Both of them have a perforating component 5 at the end away from the transport component 2.

[0032] A moving component is installed above the base plate 1 to drive the two mounting bases 4 to move back and forth.

[0033] The positioning component includes a rotating shell 6 rotatably connected to the mounting base 4. The rotating shell 6 has a mounting groove 7. A fixed plate 8 is fixed to the top of the mounting groove 7. Several clamping blocks 19 are slidably connected above the fixed plate 8 through sliding grooves 20 at equal intervals. Anti-slip pads 15 are fixed to the clamping side of the clamping blocks 19. A column rod 9 is fixed to the bottom of each of the clamping blocks 19. The mounting groove 7 is located below the fixed plate 8 and is rotatably connected to a drive plate 10 through a rotating shaft. A drive groove 11 is opened above the drive plate 10 corresponding to the column rod 9. The column rod 9 is slidably connected to the inner wall of the drive groove 11. A first motor 12 is fixed to the inner wall of the mounting groove 7. The first motor 12 is a geared motor. The output end of the first motor 12 is fixed to one end of the rotating shaft.

[0034] The mounting base 4 contains a rotating assembly that rotates the rotating housing 6.

[0035] This application sets up a positioning component so that the fixed disk 8, clamping block 19, column rod 9 and drive disk 10 cooperate to achieve precise positioning and clamping of the diaphragm. By setting up a rotating component, it is easy for the punching component 5 to punch holes around the edge of the diaphragm.

[0036] Figures 1 to 2 The second embodiment is shown. The main difference from the first embodiment is that the moving component includes a reciprocating screw 13 rotatably connected to the top of the base plate 1. Both mounting seats 4 are threaded to the outer wall of the reciprocating screw 13. A second motor 14 is fixed on the top of the base plate 1. The output end of the second motor 14 is fixed to one end of the reciprocating screw 13.

[0037] The rotating assembly includes a through slot 16 formed on the mounting base 4. A third motor 17 is fixed to the inner wall of the through slot 16. A rotating rod 18 is fixed to the lower end of the rotating housing 6. The rotating rod 18 is rotatably connected to the mounting base 4. The rotating rod 18 passes through the through slot 16 and is fixed to the output end of the third motor 17.

[0038] This application sets up a moving component to enable the reciprocating screw 13 and the second motor 14 to cooperate and realize the reciprocating movement of the two mounting seats 4. This design allows the equipment to flexibly switch the work positions on the two mounting seats 4. When the membrane is being punched above one of the mounting seats 4, the membrane can be received and positioned by the other mounting seat 4, which greatly improves the production efficiency of the membrane.

[0039] Working principle:

[0040] The transport component 2 and the clamping component 3 adopt the first transmission component, the second transmission component, the first clamping component and the second clamping component as described in CN107914315A. This is prior art and will not be described in detail here.

[0041] The transport component 2 transports the soft film and hard film to the side near the base plate 1. After the transport component 2 transports the film to the designated position, the clamping component 3 is activated to clamp and flip the soft film and hard film one by one into the fixed plate 8 on one of the mounting bases 4. Then the first motor 12 is activated to rotate the shaft, which drives the drive plate 10 to rotate, causing the column rod 9 to slide in the drive groove 11, thereby driving the clamping block 19 to move in the slide groove 20 to position the two films. Then the third motor 17 drives the rotating rod 18 to rotate, causing the rotating shell 6 to rotate, thereby driving the two positioned films to rotate. At the same time, the punching component 5 cooperates to punch holes at equal intervals on the outer edge of the double-layer film, and then the punched double-layer film is unloaded.

[0042] The second motor 14 drives the reciprocating screw 13 to rotate. Since the two mounting seats 4 are threadedly connected to the outer wall of the reciprocating screw 13, the two mounting seats 4 will reciprocate along the base plate 1. After the positioning component on one of the mounting seats 4 positions the diaphragm, the mounting seat 4 moves to the side away from the transport component 2 and performs the diaphragm punching operation. At the same time, the other empty mounting seat 4 that has completed the unloading moves to the side closer to the transport component 2 to receive the diaphragm. The two workstations are switched alternately.
