[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a battery diaphragm packaging device, which can solve the problem in the related art that the diaphragm packaging devices on the market cannot meet the requirements of manufacturers.

[0032] See also Figures 1 to 6 , a battery separator packaging device, comprising:

[0033] Frame 1;

[0034] A bottom plate 2, the bottom plate 2 is arranged on the frame 1, and there is a moving space on the bottom plate 2 for the PE diaphragm to slide;

[0035] Two seals 3, the seals 3 are respectively arranged on both sides of the bottom plate 2, and the two seals 3 are arranged opposite to each other, the seals 3 include two sealing gears 31, the two sealing gears 31 are meshed with each other, and the moving space is located between the two sealing gears 31;

[0036] like Figure 1 As shown, the frame 1 is a U-shaped frame, a bottom plate 2 is installed in the U-shaped opening of the frame 1, the bottom plate 2 is located at one end of the U-shaped opening of the frame 1, two seals 3 are symmetrically installed, and the arrangement of the two sealing gears 31 is perpendicular to the bottom plate 2;

[0037] The two sealing gears 31 of each sealing member 3 form a pair, and the two pairs of sealing gears 31 are arranged opposite to each other, and the two pairs of sealing gears 31 are located at one end of the bottom plate 2, so that the two pairs of sealing gears 31 can simultaneously seal both sides of the PE diaphragm, thereby preventing the folded PE diaphragm from being offset due to the squeezing of the sealing gears 31 on one side, and causing the PE diaphragm to be distorted or unable to be sealed on the other side if both sides of the PE diaphragm are not sealed at the same time;

[0038] In actual operation, the PE diaphragm is first folded in half from the middle, and then the PE diaphragm is placed on the bottom plate 2, and the two sides of the folding line of the PE diaphragm are respectively aligned with the two pairs of sealing gears 31, and the PE diaphragm is pushed so that the two sides of the PE diaphragm pass through the two pairs of sealing gears 31 at the same time, and the PE diaphragm is encapsulated to form a bag;

[0039] The main components of the device are only a frame 1, a base plate 2 and two seals 3. The above three components are assembled through common operations such as welding or splicing, which makes it convenient for staff to make the device easily. In the case of processing small orders, the cost of the device is significantly lower than the cost of directly purchasing assembly line manufacturing equipment on the market, thus avoiding losses for manufacturers.

[0040] The bottom plate 2 includes a fixed plate 21 and a movable plate 22;

[0041] The fixed plate 21 and the movable plate 22 are arranged opposite to each other, the fixed plate 21 is connected to the frame 1, and the movable plate 22 is slidably connected in the frame 1;

[0042] The fixed plate 21 is arranged close to the frame 1, and the fixed plate 21 is fixedly connected to the frame 1. A cross bar is installed in the frame 1, and the cross bar is parallel to the moving direction of the movable plate 22, so that the direction of the movable plate 22 is fixed when moving. Two sealing members 3 are respectively located on the fixed plate 21 and the movable plate 22;

[0043] In order to make the present application applicable to PE diaphragms of more sizes, it is necessary to adjust the distance between the two seals 3 and the width of the bottom plate 2. Therefore, the present application makes the bottom plate 2 into two parts, a fixed plate 21 and a movable plate 22, wherein the position of the fixed plate 21 remains unchanged, and the moving direction of the movable plate 22 is made perpendicular to the moving direction of the PE diaphragm through the cross bar, thereby adjusting the distance between the fixed plate 21 and the movable plate 22, and at the same time, the distance between the two seals 3 will also be adjusted.

[0044] A first screw rod 4 is provided in the frame 1;

[0045] The first screw rod 4 is threadedly connected to the moving plate 22;

[0046] The first screw rod 4 is rotatably connected to the frame 1, and the length direction of the first screw rod 4 is the same as the length direction of the first cross bar. By rotating the first screw rod 4, the thread drives the movable plate 22 to move, so as to adjust the position of the movable plate 22. At the same time, by utilizing the self-locking property of the thread, after the position of the movable plate 22 is adjusted, as long as the first screw rod 4 is not rotated again, the position of the movable plate 22 will not change, so as to achieve the purpose of fixing the position of the movable plate 22 after it moves.

[0047] It should be added that, in the present application, a turntable is rotatably connected to the frame 1, one end of the turntable is connected to the first spur gear, the first screw rod 4 is connected to the second spur gear, and the first spur gear is meshed with the second spur gear, such as Figure 2 As shown, by designing the size relationship between the first spur gear and the second gear, a better effect of rotating the turntable to drive the first screw 4 to rotate is achieved. For example, when the diameter of the first spur gear is larger than the diameter of the second spur gear, the speed at which the turntable rotates to drive the first screw 4 to rotate is faster than the speed at which the turntable directly drives the first screw 4 to rotate. When the diameter of the second spur gear is larger than the diameter of the first gear, the force required to rotate and drive the first screw 4 to rotate is smaller than the force required for the turntable to directly drive the first screw 4. Manufacturers can make adjustments as needed.

[0048] The sealing member 3 further includes a second screw 32 and a sleeve 33;

[0049] The second screw 32 is rotatably connected to a sealing gear 31, the second screw 32 is threadedly connected to a sleeve 33, and the sleeve 33 is rotatably connected to the bottom plate 2;

[0050] A U-shaped frame is fixed on the movable plate 22 and the fixed plate 21 respectively, a pair of sealing gears 31 are rotatably connected to one of the U-shaped frames, a sleeve 33 is rotatably connected to the U-shaped frame, a second screw 32 is connected to one of the sealing gears 31, a circular ring is sleeved on the second screw 32, the circular ring is fixed to the U-shape and the center of the circular ring and the center of the sleeve 33 are located on the same vertical line, so that the moving direction of the second screw 32 is limited to the length direction of the sleeve 33, and the sleeve 33 is rotated to make the second screw 32 move up and down, and at the same time drive the sealing gear 31 to move, so as to adjust the distance between the two sealing gears 31 according to the thickness of the PE diaphragm, so as to avoid the failure of encapsulation due to the excessive thickness of the PE diaphragm.

[0051] A synchronous shaft 5 is provided in the frame 1;

[0052] The synchronous shaft 5 passes through two sealing gears 31 of different sealing members 3, and the synchronous shaft 5 is rotatably connected in the frame 1;

[0053] A motor is provided on one side of the frame 1, and the synchronous shaft 5 passes through the frame 1 and is directly connected to the motor. The synchronous shaft 5 is driven by the motor to rotate on the frame 1. A convex key is provided on the synchronous shaft 5, and the convex key on the synchronous shaft 5 cooperates with the sealing gear 31, thereby realizing that the synchronous shaft 5 drives the sealing gear 31 to rotate.

[0054] Also includes two support rods 6;

[0055] Two support rods 6 are connected to the bottom plate 2, and the two support rods 6 are arranged opposite to each other on one side of the frame 1;

[0056] In actual operation, the U-shaped opening of the frame 1 is directed away from the staff, and after the PE diaphragm is encapsulated, the PE diaphragm is discharged from the U-shaped opening of the frame 1, and the staff collects the discharged PE diaphragm;

[0057] Two support rods 6 support the frame 1 so that one side of the frame 1 is higher than the other side of the frame 1, which is convenient for people to sit and operate the device of the present application. If the frame 1 is laid flat, the operator will need to stand up and put his hand on the U-shaped mouth of the frame 1 to collect the PE diaphragm.

[0058] Two rollers 7 are rotatably connected to the frame 1, and the two rollers 7 are located on one side of the bottom plate 2 close to the sealing member 3;

[0059] After the PE membrane is encapsulated, the PE membrane will pass through two rollers 7, which will flatten the folded position of the PE membrane to facilitate storage by the staff.

[0060] Baffles 8 are provided on both sides of the bottom plate 2, the two baffles 8 are arranged opposite to each other, and the sealing member 3 is located in the length direction of the baffles 8;

[0061] The baffle 8 is an L-shaped plate and the two baffles 8 are respectively located on the fixed plate 21 and the movable plate 22. During the pushing process of the PE diaphragm on the bottom plate 2, the baffle 8 can play a guiding role, guiding the PE diaphragm to the two seals 3, which is convenient for the staff to operate.

[0062] Here’s how this application works:

[0063] Before the specific operation of the present application, the device is placed on the desktop, with the U-shaped opening of the frame 1 facing away from the staff, and then the distance between the fixed plate 21 and the movable plate 22 and the spacing between the two sealing gears 31 are adjusted by the first screw 4 and the second screw 32 according to the width and thickness of the PE diaphragm. During operation, the PE diaphragm is first folded, and then the PE diaphragm is placed on the fixed plate 21 and the movable plate 22. The PE diaphragm is pushed through the two seals 3 by the guidance of the baffle 8. At the same time, after passing through the two seals 3, the PE diaphragm will pass through the two rollers 7. The two rollers 7 flatten the folded position of the PE diaphragm. Finally, the staff will encapsulate and store the PE diaphragm.
