[0040] In this embodiment, the bottom cover 701 and the top cover 702 are sequentially conveyed by the conveying mechanism 3. Figure 1For example, the entire device runs, the first conveying mechanism 3 starts, a number of evenly distributed bottom cover 701 intermittent to the top of the electric control turntable 1 conveying, while the electric control turntable 1 starts synchronously, with the loading of each bottom cover 701 occurs intermittently rotating, the clockwise rotating electric control turntable 1 will be transported to the bottom cover 701 to the bottom of the filling mechanism 4, at this time the filling mechanism 4 starts to run, in a single run way first a cotton filter 703 filled to the inside of the bottom cover 701, while filling the inside of the bottom cover 701 with a fixed amount of activated carbon 704, after continue to fill a cotton filter 703 to the inside of the bottom cover 701, so that the internal structure of the bottom cover 701 is two cotton filter 703 between the activated carbon 704 clamping, complete the cotton filter 703 and activated carbon 704 filling, continue to rotate the electric control turntable 1 will be filled with the bottom cover 701 to the bottom of the compaction mechanism 5, compaction mechanism 5 starts and compacts the activated carbon 704 in the bottom cover 701, after completing the compaction, continue to rotate the electric control turntable 1 will be transported to the bottom cover 701 to the bottom of another conveying mechanism 3, the conveying mechanism 3 will be a number of evenly distributed top cover 702 intermittent to the top of the electric control turntable 1 conveying, and cover on the corresponding bottom cover 701 top, at this time continue to rotate the electric control turntable 1 will be transported to the bottom cover 701, top cover 702 assembly to the bottom of the ultrasonic welding machine 6, the ultrasonic welding machine 6 starts, driving the welding head down and clamping on the top of the top cover 702, in a heated way to the bottom cover 701 and top cover 702 joint welding, let the bottom cover 701 and top cover 702 combined into a complete filter box 7, after continue to rotate the electric control turntable 1 will be transported to the finished filter box 7 to the last conveying mechanism 3 position and conveying away, complete the whole work flow.

[0041] Wherein, the top of the electric control turntable 1 is evenly installed with a number of card seat 101, the bottom cover 701 is placed in the inside of the card seat 101, maintaining the stability of the bottom cover 701 on the top of the electric control turntable 1.

[0042] Further, the output end of the ultrasonic welding machine 6 is fixedly installed with a welding sleeve 601 at the bottom, the welding sleeve 601 clamping on the top of the top cover 702, improving the stability of the ultrasonic welding machine 6 when welding the top cover 702.

[0043] Referring to Figures 1 to 2In a preferred embodiment, the conveying mechanism 3 comprises a plurality of racks 301 fixed on the top of the workbench 2, the top of the rack 301 is fixedly provided with an electric control sliding rail 302, the moving end of the electric control sliding rail 302 is provided with a pneumatic clamp jaw 303, the side of the rack 301 is provided with a conveying belt 304, the conveying belt 304 is arranged on the ground, and the bottom of the conveying belt 304 is fixedly provided with a servo motor 305 driven by a belt, and the top of the two conveying belts 304 is respectively stacked with a bottom cover 701 and a top cover 702.

[0044] Taking the conveying and feeding of the bottom cover 701 as an example, when in operation, the servo motor 305 rotates and drives the conveying belt 304 to rotate through the belt, and the top of the conveying belt 304 is provided with a plurality of uniformly distributed bottom covers 701 through a preprogram, the rotating conveying belt 304 conveys the bottom cover 701 to the bottom of the pneumatic clamp jaw 303, when a single bottom cover 701 is conveyed to the position directly below the pneumatic clamp jaw 303, at this time, the servo motor 305 controls the conveying belt 304 to pause conveying, and the pneumatic clamp jaw 303 is started to clamp and fix the bottom cover 701 below, after clamping, the electric control sliding rail 302 is started to drive the pneumatic clamp jaw 303 and the clamped bottom cover 701 to move horizontally and move to the top of the electric control turntable 1, at this time, the pneumatic clamp jaw 303 stops running and releases the clamping of the bottom cover 701, and the bottom cover 701 is placed on the top of the electric control turntable 1, and the above-mentioned operation is repeated to intermittently feed the top of the electric control turntable 1; the conveying mechanism 3 for feeding the top cover 702 is the same as above, and the conveying mechanism 3 for conveying the finished product filter box 7 is operated in reverse, so as to unload the finished product filter box 7.

[0045] With reference to Figures 5 to 8 In a preferred embodiment, in the filling mechanism 4, the number of the backing plates 405 is a plurality and is distributed in a spiral staggered manner, the inside of the barrel 403 is uniformly stacked with a plurality of cotton filter sheets 703, the rotating backing plate 405 cuts into the inside of the barrel 403 and is placed on the bottom of a cotton filter sheet 703, the bottom of the carbon box 401 and the barrel 403 are throughly connected with a material pipe 407, the end of the material pipe 407 is provided with an electromagnetic valve 408, the side of the carbon box 401 is distributed with a vertical rod 409, the top of the vertical rod 409 is vertically provided with an electric push rod 410, the output end of the electric push rod 410 is fixedly provided with a pressing plate 411, and the pressing plate 411 is in extrusion contact with the top of the cotton filter sheet 703 in the inside of the barrel 403.

[0046] In this embodiment, the electric control turntable 1 rotating clockwise conveys the bottom cover 701 to the bottom of the barrel 403, at this time, the stepping motor 404 starts to operate, the stepping motor 404 rotates intermittently to drive the electric control turntable 1 to rotate and move the bottom cover 701 to the bottom of the barrel 403, and the bottom cover 701 is in the position directly below the barrel 403. Figure 8For example, at this time, the rotating stepper motor 404 drives all the pads 405 to rotate. In the initial state, the lowermost pad 405 is located inside the barrel 403, and the cotton filter 703 inside the barrel 403 is placed on the surface of the pad 405. With the rotation of the pad 405, the lowermost pad 405 gradually moves out of the inside of the barrel 403 until the lowermost cotton filter 703 loses support and falls. The adjacent pad 405 above gradually cuts into the outside of the barrel 403 and is inserted into the bottom of the remaining cotton filter 703 to form support. Each rotation of the stepper motor 404 will only release one cotton filter 703 to fall. The falling cotton filter 703 will fall into the inside of the bottom cover 701. At this time, the stepper motor 404 stops running, and the electromagnetic valve 408 starts to quantitatively guide the activated carbon 704 inside the carbon box 401 into the inside of the bottom cover 701 through the pipe 407. After the activated carbon 704 is guided into the inside of the bottom cover 701, the electromagnetic valve 408 stops running. Then, the stepper motor 404 restarts, and the above operation is repeated to continue to lower one cotton filter 703 into the inside of the bottom cover 701, so that the inside structure of the bottom cover 701 is that the activated carbon 704 is clamped between two cotton filters 703. After the filling of the cotton filter 703 and the activated carbon 704 is completed, the continuously rotating electrically controlled turntable 1 transfers the filled bottom cover 701 to the bottom of the compaction mechanism 5.

[0047] It is worth noting that after all the pads 405 rotate as a whole and rotate one circle, if the pads 405 continue to rotate forward, the uppermost pad 405 will be separated from the barrel 403, and at this time the cotton filter 703 above will fall to the surface of the lowermost pad 405 due to its own gravity. The falling distance is large in this state, which can easily cause the cotton filter 703 to tilt. Therefore, in order to avoid this situation, after all the pads 405 rotate as a whole and rotate one circle, the stepper motor 404 is reversed at this time, so that several cotton filters 703 fall from top to bottom layer by layer until they fall to the surface of the lowermost pad 405. At this time, the stepper motor 404 resumes forward rotation. In this way, the reverse rotation is repeated to complete the periodic operation. The reverse rotation speed is fast, and it is performed during the idle period of the rotation of the clamping seat 101 driven by the electrically controlled turntable 1, and it will not affect the production efficiency of the equipment.

[0048] At the same time of the rotation of the stepper motor 404, the elastic wave wheel 406 at the bottom of the output shaft of the stepper motor 404 will rotate synchronously and impact the bottom cover 701, causing the bottom cover 701 to vibrate and shake the activated carbon 704 inside.

[0049] Specifically, the elastic wave wheel 406 is composed of a plurality of elastic pieces. With the rotation of the output shaft of the stepper motor 404, the elastic pieces of the elastic wave wheel 406 will contact the outside of the bottom cover 701, and the elastic pieces will deform due to their own elasticity, facilitating their detachment from the outside of the bottom cover 701.

[0050] It is worth noting that the inner opening size of the card seat 101 is the same as the outer opening size of the bottom card cover 701, and the elastic wave wheel 406 does not affect the position of the bottom card cover 701 during the process of pushing the bottom card cover 701.

[0051] Further, as shown in Figure 6 and Figure 7 , the inner wall of the barrel 403 is provided with an inner recess 4031, and the inner wall of the barrel 403 and the inner recess 4031 form a structure with wide upper and lower ends and narrow middle. The upper end is wide to better load the cotton filter disc 703, the middle is narrow to shape the cotton filter disc 703, and the lower end is wide to better unload the cotton filter disc 703 and avoid excessive friction between them to affect the cutting of the backing plate 405 and the unloading operation;

[0052] Specifically, after the worker supplements the cotton filter disc 703 inside the barrel 403, the electric push rod 410 is started at this time, and moves the pressing plate 411 downward through the output shaft. When the cotton filter disc 703 pressed by the pressing plate 411 passes the position of the inner recess 4031, the edge of the cotton filter disc 703 will bend upward. When the cotton filter disc 703 in this state is subjected to the horizontal cutting force of the backing plate 405, as shown in Figure 11 , the edge of the backing plate 405 will extrude the edge of the cotton filter disc 703, causing it to deform upward, so that the backing plate 405 can more easily cut between the two cotton filter discs 703 (if the edge of the cotton filter disc 703 is flat, the backing plate 405 will be difficult to cut between the two cotton filter discs 703 during horizontal cutting, and the edge of the cotton filter disc 703 will be easily cut), and when the cotton filter disc 703 is unloaded, as shown in Figure 10 , the edge of the cotton filter disc 703 will more fully fit the inner wall of the bottom card cover 701, preventing subsequent activated carbon 704 from leaking.

[0053] It is worth noting that the position of the backing plate 405 is below the inner recess 4031, and the cotton filter disc 703 shaped from the inner recess 4031 will accumulate on the surface of the backing plate 405, and the distance between the two backing plates 405 is equal to the thickness of one shaped cotton filter disc 703, ensuring that only one cotton filter disc 703 can be unloaded at a time, and the control is more precise.

[0054] The bottom of the barrel 403 is provided with a plurality of evenly distributed inner cutting grooves 4032, and the backing plate 405 cuts into the inside of the barrel 403 through the inner cutting grooves 4032, and the thickness of the inner cutting grooves 4032 is the same as that of the backing plate 405;

[0055] Specifically, as shown in Figure 8 and Figure 11As shown, the outer edge of each gusset plate 405 is provided with a chamfered portion 4051; the chamfered portion 4051 can be more effectively inserted between the two cotton filter sheets 703 when in contact with the edge of the curved cotton filter sheet 703, and the chamfered portion 4051 can reduce the cutting resistance.

[0056] With reference to Figure 1 , Figure 5 and Figure 9 In a preferred embodiment, the compaction mechanism 5 includes a bracket 501 fixedly installed on the top of the workbench 2, a rotating rod 502 is rotatably installed on the top of the bracket 501, an electric motor 503 is fixedly installed on the side of the top of the bracket 501, and the output shaft of the electric motor 503 penetrates into the interior of the bracket 501 and is fixedly connected with the rotating end of the rotating rod 502.

[0057] After the cotton filter sheet 703 and the activated carbon 704 are filled, the continuously rotating electric control turntable 1 transfers the filled bottom cover 701 to the bottom of the compaction mechanism 5, at this time the electric motor 503 is started and drives the rotating rod 502 to rotate around the bracket 501, so as to compact the activated carbon 704 in the interior of the bottom cover 701.

[0058] It is worth noting that since the outer opening size of the cotton filter sheet 703 is larger than the inner opening size of the bottom cover 701, the compaction mechanism 5 of the present application needs to additionally provide a set of compaction mechanism near the filling mechanism 4 (not shown in the figure), which can compact the filled first cotton filter sheet 703, and ensure that the cotton filter sheet 703 is located at the bottom of the bottom cover 701. This means is a conventional design, and will not be described in detail.

[0059] Specifically, the end of the rotating rod 502 is fixedly installed with a rubber plate 504, and the rotating rotating rod 502 will drive the rubber plate 504 to extrude and contact the cotton filter sheet 703 in the interior of the bottom cover 701, so as to form a flexible extrusion on the cotton filter sheet 703.

[0060] Working principle: when in use, Figure 1For example, during the entire device operation, the first conveying mechanism 3 starts, the servo motor 305 rotates and drives the conveyor belt 304 to rotate through the belt, and the top of the conveyor belt 304 is provided with a plurality of evenly distributed bottom cover plates 701 through the preprogram. The rotating conveyor belt 304 transports the bottom cover plate 701 to the bottom of the pneumatic clamp 303. When a single bottom cover plate 701 is transported to the position directly below the pneumatic clamp 303, the servo motor 305 controls the conveyor belt 304 to pause transportation at this time, and the pneumatic clamp 303 starts to clamp and fix the bottom cover plate 701 located below. After clamping, the electric control sliding rail 302 starts to drive the pneumatic clamp 303 and the clamped bottom cover plate 701 to move horizontally and move to the top of the electric control turntable 1. At this time, the pneumatic clamp 303 stops running and releases the clamping of the bottom cover plate 701, and the bottom cover plate 701 is placed on the top of the electric control turntable 1. In this way, intermittent feeding is carried out on the top of the electric control turntable 1.

[0061] At the same time, the electric control turntable 1 starts synchronously and rotates intermittently with the feeding of each bottom cover plate 701. The clockwise rotating electric control turntable 1 transports the bottom cover plate 701 to the bottom of the filling mechanism 4. At this time, the stepping motor 404 starts to run, and the stepping motor 404 rotates intermittently to drive all the pads 405 to rotate. Figure 8 For example, at this time, the rotating stepping motor 404 drives all the pads 405 to rotate. In the initial state, the lowermost pad 405 is located inside the barrel 403, and the cotton filter disc 703 inside the barrel 403 is placed on the top of the pad 405. With the rotation of the pad 405, the lowermost pad 405 gradually moves out of the inside of the barrel 403, until the lowermost cotton filter disc 703 loses support and falls, and the adjacent pad 405 above gradually cuts into the outside of the barrel 403 and is inserted into the bottom of the remaining cotton filter disc 703 to form support. Each time the operation releases one cotton filter disc 703 to fall. The falling cotton filter disc 703 will fall into the inside of the bottom cover plate 701. At this time, the stepping motor 404 stops running, and the electromagnetic valve 408 starts to quantitatively guide the activated carbon 704 inside the carbon box 401 into the inside of the bottom cover plate 701 through the feeding auger inside the pipe 407. After that, the electromagnetic valve 408 stops running, and the stepping motor 404 starts to repeat the above operation to continue to lower one cotton filter disc 703 into the inside of the bottom cover plate 701, so that the internal structure of the bottom cover plate 701 is that the activated carbon 704 is clamped between two cotton filter discs 703. After the filling of the cotton filter disc 703 and the activated carbon 704 is completed, the continuously rotating electric control turntable 1 transports the filled bottom cover plate 701 to the bottom of the compaction mechanism 5.

[0062] At this time, the electric motor 503 starts and drives the rotating rod 502 to rotate around the support 501, so as to compact the activated carbon 704 inside the bottom cover 701. After the compaction is completed, the continuously rotating electric control turntable 1 delivers the bottom cover 701 to the bottom of another conveying mechanism 3. The conveying mechanism 3 intermittently delivers a plurality of top covers 702 which are uniformly distributed to the top of the electric control turntable 1 and are covered on the top of the corresponding bottom cover 701. At this time, the continuously rotating electric control turntable 1 delivers the bottom cover 701 and the top cover 702 assembly to the bottom of the ultrasonic welding machine 6. The ultrasonic welding machine 6 starts, drives the welding head to press down and be clamped on the top of the top cover 702, so as to weld the joint between the bottom cover 701 and the top cover 702, and combine the bottom cover 701 and the top cover 702 into a complete filter box 7. After that, the continuously rotating electric control turntable 1 delivers the finished filter box 7 to the position of the last conveying mechanism 3 and delivers it away, and the whole working process is completed.

[0063] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, and all of them should be covered within the protection scope of the present application.
