Description

Technical Field

[0001] This invention relates to the field of explosion-proof valve protective patch technology, specifically to a pressing device for preparing explosion-proof valve protective patches. Background Technology

[0002] The explosion-proof valve patch is attached to the outside of the battery explosion-proof valve. It mainly serves to prevent dust, water, and debris from entering. At the same time, it ensures that the explosion-proof valve can be broken through smoothly when it is depressurized, without hindering the release of high-pressure gas inside the battery. It also prevents the valve port from being blocked by foreign objects and thus prevents it from failing. It balances protection and pressure relief safety, and reduces the risk of battery explosion.

[0003] Chinese patent application number 202411874064.4 discloses a pressing device, including: a frame, a pressing mechanism fixedly installed on the top of the frame, a guide mechanism fixedly installed on one side of the top of the pressing mechanism, and a bubble scraping mechanism fixedly installed on the other side of the top of the pressing mechanism; wherein, the pressing mechanism includes a fixed frame, the fixed frame is fixedly installed on the top of the frame, and a sliding groove plate is fixedly installed at the center position on both sides of the fixed frame, and a slot is formed at the center position of the top outer side of the sliding groove plate;

[0004] In the preparation process of explosion-proof valve protective patches, the release film and the breathable film are mainly pressed and laminated, and then cut into the corresponding shapes. During the pressing process, if the pressing force is too large, the adhesive between the two films is easily squeezed out from the side of the film, which will affect the subsequent use and result in poor quality of the prepared patch.

[0016] Preferably, the exhaust assembly includes a second drive motor, which is fixedly connected to the outer wall of the support frame. A dial wheel is provided at the top of the conveyor belt, and multiple actuation components are provided on the outer wall of the dial wheel. A film feeding roller group is provided on the left side of the dial wheel, and an air-push component is provided at the bottom of the film feeding roller group.

[0017] Preferably, the actuating assembly includes a pop-out plate, which is movably connected inside the dial wheel. A limiting rod corresponding to the pop-out plate is fixedly connected inside the dial wheel, and the limiting rod can limit the pop-out plate to prevent it from flying outward. A spring is fixedly connected inside the dial wheel and is fixedly connected to the pop-out plate. An actuating roller is movably connected to the outside of the pop-out plate.

[0018] Preferably, the pneumatic assembly includes an air outlet box, which is fixedly connected inside the support frame and located at the top of the conveyor belt. The air outlet box has multiple exhaust ports on the side near the dial wheel. A baffle plate is fixedly connected to the bottom of the air outlet box.

Exhaust ports are provided on both the front and back of the support frame at positions corresponding to the dial wheel.

[0019] This invention provides a pressing device for preparing explosion-proof valve protective patches. It has the following beneficial effects:

[0020] 1. The pressing equipment for preparing explosion-proof valve protective patches controls the extrusion pressure of low-pressure airbags and high-pressure airbags on the bonding film through the pressure control component. During the extrusion process, the adhesive is hindered by the pressure of the high-pressure airbag, which prevents the central part from being compressed and causing the adhesive to be squeezed out through the edge of the bonding film, thereby improving the preparation quality of the bonding of the breathable film and the release film.

[0021] 2. The pressing equipment for preparing the explosion-proof valve protective patch can move from right to left on the surface of the release film by turning the component. The release film can be easily pushed under the support of the airflow, and the air between the release film and the breathable film is pushed to the left, so as to avoid the presence of air bubbles between the breathable film and the release film, which would affect the preparation quality.

[0022] 3. The pressing equipment for preparing explosion-proof valve protective patches uses a pressure-dividing component to fix the film during the pressing process. The damping effect between the agitator roller and the ejector plate can pull the release film to the left. Combined with the lifting effect of airflow to reduce contact resistance, it can better smooth out the wrinkled parts and improve the preparation quality.

[0023] 4. The pressing equipment for preparing the explosion-proof valve protective patch discharges air through the air outlet box, causing the air to blow towards the release film. Excess air will be discharged through the gap between the air push assembly and the breathable film and the exhaust port. Since the airflow passes through the filter, the airflow is pushed outward, which can prevent external dust from entering between the release film and the breathable film, thus improving the preparation quality of the bonding between the breathable film and the release film.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0037] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a pressing device for preparing explosion-proof valve protective patches, including a support frame 1, a conveyor belt 2 inside the support frame 1, a support platform 5 inside the conveyor belt 2, a pressing mechanism 3 on the top of the conveyor belt 2, and an exhaust component 4 on the left side of the pressing mechanism 3 on the top of the conveyor belt 2.

[0038] The pressing mechanism 3 includes:

[0039] Rotating rod 31 is installed on the top of the bearing frame 1;

[0040] The first drive motor 32 is located on the outside of the support frame 1, and the output shaft of the first drive motor 32 is fixedly connected to the rotating rod 31.

[0041] Pressure divider assembly 33 is provided on the outer wall of rotating rod 31;

[0042] Pressure control component 34 is disposed inside the rotating rod 31.

[0043] The breathable membrane is placed on top of the conveyor belt 2 with the adhesive side facing upwards. At the same time, the release membrane is placed on top of the breathable membrane after being processed by the venting component 4. It is then pushed to the right by the conveyor belt 2 and smoothed by the venting component 4, so that the release membrane is on top of the breathable membrane and at the bottom of the rotating rod 31. It is then pressed by the pressure dividing component 33 to bond the release membrane with the breathable membrane. The bonded material can then be sent to the cutting equipment.

[0044] The pressure dividing assembly 33 includes a low-pressure airbag 331, a rotating rod 31 located inside the low-pressure airbag 331 with an exhaust port, the low-pressure airbag 331 being fixedly connected to the outer wall of the rotating rod 31, and high-pressure airbags 332 being provided on both sides of the outer wall of the rotating rod 31 located on the low-pressure airbag 331.

[0045] The end of the rotating rod 31 away from the first drive motor 32 is movably connected to the rotating pipe 333 via a sealed bearing. The end of the rotating pipe 333 away from the first drive motor 32 is fixedly connected to the blower 334. The air inlet of the blower 334 away from the rotating pipe 333 is fixedly connected to the filter 335.

[0046] Blower 334 draws in clean air filtered by filter 335, and then delivers the drawn air through pressure divider 33 into rotor 31. The air delivered into low-pressure airbag 331 enters the low-pressure airbag 331 through the corresponding exhaust port. Then, under the control of high-pressure airbag 332, the low-pressure airbag 331 maintains a lower pressure, while the high-pressure airbag 332 maintains a higher pressure. At the same time, first drive motor 32 drives rotor 31 to rotate, further driving the low-pressure airbag 331 and high-pressure airbag 332 to rotate. The rotation of the airbag 332 causes both airbags to press the two laminated films under pressure. During this process, the high-pressure airbag 332 exerts a greater pressing force on the edge of the film. When the low-pressure airbag 331 presses the central part of the adhesive outward, the adhesive is hindered by the pressing force of the high-pressure airbag 332, preventing the central part from being pressed and causing the adhesive to be squeezed out through the edge of the laminated film. In addition, there is a gap between the low-pressure airbag 331 and the high-pressure airbag 332, which can provide a buffer space for the squeezed adhesive and further prevent the adhesive from being squeezed out.

[0047] The pressure control assembly 34 includes an inner tube 344, which is fixedly connected to the inside of the rotating rod 31. One end of the inner tube 344 away from the first drive motor 32 is a closed end, and the other end is an open end. A baffle plate 345 is fixedly connected to the inside of the rotating rod 31 at the open end of the inner tube 344. An exhaust port is provided on the outer wall of the rotating rod 31 on the side of the baffle plate 345 near the first drive motor 32.

[0048] Two isolation plates 341 are fixedly connected to the outer wall of the rotating rod 31. The isolation plates 341 are located at the junction of the low-pressure airbag 331 and the high-pressure airbag 332. A first overflow valve 342 is fixedly connected to the outer wall of each isolation plate 341. A second overflow valve 343 is provided inside each high-pressure airbag 332. The second overflow valve 343 passes through the rotating rod 31 and is fixedly connected to the inner tube 344. The overflow threshold of the second overflow valve 343 is higher than that of the first overflow valve 342.

[0049] After air is pushed into the rotating rod 31, the air inside the rotating rod 31 enters the low-pressure airbag 331 through the corresponding exhaust port, causing the low-pressure airbag 331 to inflate. This causes the low-pressure airbag 331 to exert pressure on the bottom diaphragm. When the air pressure threshold inside the low-pressure airbag 331 exceeds the set value of the first overflow valve 342, the excess air enters the two high-pressure airbags 332 through the corresponding first overflow valve 342, causing the high-pressure airbags 332 to inflate. When the pressure inside the bladder 332 is too high, the corresponding air will enter the inner tube 344 through the second overflow valve 343. Since the overflow threshold of the second overflow valve 343 is higher than that of the first overflow valve 342, the air pressure inside the high-pressure bladder 332 is higher than that of the low-pressure bladder 331. This will cause the pressure of the high-pressure bladder 332 on the adhesive membrane to be greater than that of the low-pressure bladder 331. The air discharged into the inner tube 344 will flow towards the baffle plate 345 and be discharged through the corresponding exhaust port.

[0050] Example 2: Please refer to Figure 1-10 Based on Embodiment 1, the present invention provides the following technical solution:

[0051] The exhaust assembly 4 includes a second drive motor 41, which is fixedly connected to the outer wall of the support frame 1. A dial wheel 42 is provided on the top of the conveyor belt 2. Multiple actuation components 43 are provided on the outer wall of the dial wheel 42. A film feeding roller group 44 is provided on the left side of the dial wheel 42. An air-push assembly 45 is provided at the bottom of the film feeding roller group 44.

[0052] The release film is held and transported by the film feeding roller group 44. The film feeding roller group 44 maintains a certain speed and transports the release film to the right, so that the film feeding roller group 44 passes the bottom of the actuating component 43. During this process, the air push component 45 discharges airflow, which blows towards the release film actuating component 43, causing the release film to bulge upward. This prevents the bottom of the release film from contacting the breathable film on the left side of the actuating wheel 42. During this process, the actuating component 43 is driven by the second drive motor 41 to drive the actuating wheel 42, causing the actuating component 43 to rotate clockwise. The actuating component 43 moves from right to left on the surface of the release film. The part of the release film on the left side of the actuating wheel 42 can be easily pushed by the airflow. This allows the actuating component 43 to push the folds of the release film to the left during the movement and push the air between the release film and the breathable film to the left.

[0053] The actuating assembly 43 includes a pop-out plate 431, which is movably connected inside the dial 42. A limiting rod 433 corresponding to the pop-out plate 431 is fixedly connected inside the dial 42, and the limiting rod 433 can limit the pop-out plate 431 to prevent it from flying outward. A spring 434 is fixedly connected inside the dial 42 and is fixedly connected to the pop-out plate 431. An actuating roller 432 is movably connected to the outside of the pop-out plate 431, and the rotation structure of the actuating roller 432 and the pop-out plate 431 is damped.

[0054] As the dial wheel 42 is driven to rotate by the second drive motor 41, the ejector plate 431 gradually moves from the top of the dial wheel 42 to the bottom of the dial wheel 42. When the ejector plate 431 contacts the top of the release film, it will adhere to the surface of the release film and move to the left under the push of the spring 434. This can push the air bubbles between the release film and the breathable film to the left. Since the left side of the release film is lifted by the airflow, it can more easily expel the air bubbles. At the same time, the pressure distribution component 33 on the right side presses the two films together and has a fixing effect on the film. The damping effect between the dial roller 432 and the ejector plate 431 will pull the release film to the left. The airflow can also reduce the contact resistance of the release film when it moves to the left on the surface of the breathable film, and can better flatten the wrinkled parts.

[0055] The pneumatic assembly 45 includes an air outlet box 451, which is fixedly connected inside the support frame 1 and located at the top of the conveyor belt 2. The air outlet box 451 has multiple exhaust ports on the side near the dial wheel 42. A baffle plate 452 is fixedly connected to the bottom of the air outlet box 451. A connecting pipe 454 is fixedly connected to the outer wall of the air outlet box 451, and a connecting cover 455 is fixedly connected to the end of the connecting pipe 454 away from the air outlet box 451. The connecting cover 455 is fixedly connected to the outer wall of the support frame 1. Exhaust ports 453 are opened on the front and back of the support frame 1 at the corresponding positions of the dial wheel 42. Air discharged from the outer wall of the rotating rod 31 to the outside of the support frame 1 will enter the interior of the connecting cover 455.

[0056] Air passes through the connecting cover 455 and then through the connecting pipe 454 into the air outlet box 451. The air is then discharged through the air outlet box 451, causing the air to blow towards the release membrane. In addition, excess air is discharged through the gap between the air push assembly 45 and the breathable membrane and the exhaust port 453, thereby lifting the release membrane with air. Furthermore, the airflow is filtered by the filter 335 and pushed outward, which can prevent external dust from entering between the release membrane and the breathable membrane.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
