Description

Technical Field

[0002] Car carpet is an important part of car interior and is usually laid on the vehicle floor. After the car carpet is produced and formed, the entire carpet needs to be cut and trimmed by equipment. During the cutting and trimming process, a large amount of waste such as lint will be generated, affecting the air environment.

[0003] At present, in order to prevent the lint and other wastes generated during carpet production from randomly scattering and affecting the surrounding air environment, it is necessary to collect and filter the lint and other wastes in the air through an air filtration system to reduce the lint and other wastes in the air.

For example, a composite air filtration system for automobile carpet production disclosed in patent publication number CN213885438U;

[0037] The operating principle of the present invention is described as follows: the entire device is installed at a suitable position in the car carpet production workshop, and each suction hopper 6 is located above the cutting and repairing car carpet station, and then the controller 19 is connected to the external power supply circuit, and the dust collection bag 182 is installed at the end of each L-shaped tube 181, and then the controller 19 is started;

[0038] After the controller 19 is started, it will control the fan 2 to work. The suction end of the fan 2 will generate negative pressure suction force in each suction hopper 6 through the suction pipe 4 and the hollow plate 5. Under the action of the negative pressure suction force, the fluff at the cutting and repairing stations will be sucked into the suction hopper 6 along with the air. After the controller 19 is started, each arc light board 73 will be started synchronously, and the connection circuit between each first electromagnetic push rod 82 and the multiple arc photoresistor strips 75 on the same side will be connected at the same time. When the arc light board 73 is working, it will emit light, and the light will be projected to each arc photoresistor strip 75 on the same side. If the content of fluff and other waste in the airflow entering the suction hopper 6 is small, it will pass through The fluff and other wastes at the arc lamp panel 73 block less light. At this time, the light intensity projected to the arc photoresistor strip 75 is relatively high, and the resistance of the arc photoresistor strip 75 decreases significantly (the light intensity detection range of the arc photoresistor strip 75 is between 50 Lux and 300 Lux. Within this range, the light intensity increases and the resistance of the arc photoresistor strip 75 decreases). At this time, the current passing into the first electromagnetic push rod 82 on this side becomes larger. Therefore, the magnetic thrust generated by the electromagnetic part inside the first electromagnetic push rod 82 becomes larger. Therefore, the first electromagnetic push rod 82 pushes the air inlet cylinder 83 downward by a larger distance. At this time, the air inlet hole at the air inlet cylinder 83 84 is more blocked by the rubber sleeve 85 on the same side. Therefore, when the content of waste such as fluff at the air suction hopper 6 is less, the air inlet 83 on this side moves down a large distance, and the air inlet hole 84 is more blocked by the rubber sleeve 85, and the channel for air flow to enter is small. If the content of waste such as fluff at the air suction hopper 6 is more, the fluff blocks more light, resulting in a lower light intensity at the arc-shaped photoresistor strip 75. At this time, the resistance of the arc-shaped photoresistor strip 75 is large. Therefore, the current passing into the first electromagnetic push rod 82 is small, so the air inlet 83 on this side moves down a small distance. Therefore, the air inlet hole 84 at the air inlet hopper 83 on this side is blocked by the rubber sleeve 85 on the same side. Less, so the side air inlet 83 has a larger channel for airflow to enter. Therefore, during the operation of the fan 2, under the same power, by reducing the air inlet channel at the position where the amount of waste such as lint is small, and increasing the air inlet channel at the position where the amount of waste such as lint is large, the timeliness and sufficiency of the adsorption at the position where the amount of waste such as lint is large can be improved, and the possibility of the waste such as lint escaping can be reduced (due to the cutting and repairing of the entire car carpet, the position where the waste such as lint is generated will also change due to the change of the cutting position and the repairing position. Therefore, by reasonably allocating the negative pressure suction of each suction bucket 6, the waste such as lint in the air can be better adsorbed);

[0039] After the controller 19 is started, the connection circuit between all the arc-shaped photoresistor strips 75 and the third electromagnetic push rod 203 will be synchronously connected. When the fluff content in the air is relatively high, the fluff will block the light irradiated to each arc-shaped photoresistor strip 75. Therefore, the resistance of each arc-shaped photoresistor strip 75 is relatively large. At this time, the current passed into the third electromagnetic push rod 203 is relatively small, so the moving distance of the third electromagnetic push rod 203 pushing the touch-pressure square column 204 is small. When the touch-pressure square column 204 is pushed by the third electromagnetic push rod 203, the touch-pressure square column 204 will squeeze the arc-shaped squeezing block 205 on the moving contact of the pressure switch 202. In the extreme case (that is, when the fluff content in the air in all the air suction buckets 6 is higher than 70%), the third electromagnetic push rod 203 will be pressed. The push rod 203 cannot push the contact pressure square column 204 to move. At this time, the moving contacts of each pressure switch 202 will not be closed. Therefore, each second electromagnetic push rod 122 will not be energized, so each auxiliary air outlet hopper 11 will remain in an open state. At this time, the wind flow containing waste such as fluff discharged by the fan 2 (the fan blades of the fan 2 are curved, so that the airflow is smoother when passing through the fan blades, reducing the resistance of the airflow, making it easier for the fluff to pass through with the airflow without adhering to the fan blades, and the surface of the fan blades is coated with a Teflon coating, which has extremely low surface energy and non-stickiness, making it difficult for the fluff to adhere to the surface of the fan blades, ensuring that the fluff can pass smoothly) will be discharged from each main air outlet hopper 10 and each auxiliary air outlet hopper 11 respectively. Due to the high content of fluff in the wind flow, The fluff content in the wind flow passing through each main air outlet scoop 10 and each auxiliary air outlet scoop 11 will also be relatively high, and since the aperture of the air outlet end of each main air outlet scoop 10 and each auxiliary air outlet scoop 11 is small, the fluff will be gathered together and discharged after entering the main air outlet scoop 10 and the auxiliary air outlet scoop 11, so that the fluff can be concentrated together as much as possible and discharged in a group, so that the large fluff can wrap part of the small fluff, thereby reducing the possibility of the escape of small-sized fluff. If the content of fluff and other waste in the wind flow entering each air inlet scoop is relatively low, at this time, the light intensity projected to each arc-shaped photoresistor strip 75 is large, so the resistance of each arc-shaped photoresistor strip 75 is relatively small, and therefore the current passing into the third electromagnetic push rod 203 is large, and at this time the moving distance of the touch-press square column 204 is The distance between the pressure switches 202 and the pressure switches 202 squeezed by the square column 204 through the arc-shaped squeezing block 205 is large, and each time a pressure switch 202 is closed, the corresponding second electromagnetic push rod 122 will be energized, and after the second electromagnetic push rod 122 is energized, it will push the baffle 123 on the same side to abut against the side wall of the baffle plate 9, so that the auxiliary air outlet 11 here can be sealed. In the extreme case (that is, when the fluff content in the air in all the suction hoppers 6 is lower than 20%), all the pressure switches 202 will be closed. At this time, all the second electromagnetic push rods 122 will push the baffle 123 on the same side to seal the auxiliary air outlet 11. At this time, the discharged airflow will be concentrated in each main air outlet hopper 10 for discharge, so that when the amount of fluff is small,Make the fluff discharged as concentratedly as possible;

[0040] The wind flow discharged through the main air outlet 10 and the auxiliary air outlet 11 will directly contact the plastic bristles 15 on the leather belt 14. Under the action of the plastic bristles 15, the hair can be entangled, so as to achieve the effect of removing most of the hair. After the controller 19 is started, the belt drive mechanism 13 will be started synchronously. The belt drive mechanism 13 will drive the plastic bristles 15 to rotate in a circular manner through the leather belt 14, so as to entangle and remove the hair in the wind flow that is continuously discharged. When the belt drive mechanism 13 is working, it will drive the roller 161 to rotate through the chain transmission component 164. Under the action of the roller 161, each mounting plate 162 will also drive the combing glass needle 163 to rotate synchronously. Since the roller 161 rotates in the same direction as the roller shaft of the belt drive mechanism 13, the combing glass The needle 163 can remove the fluff wound around the plastic bristles 15 by pushing it downwards, thus preventing the fluff from being too much wound around the plastic bristles 15. At the same time, after the combing glass needle 163 contacts and rubs against the plastic bristles 15, charge transfer will occur, thereby causing the plastic bristles 15 to generate static electricity. The static electricity will form an electric field on the plastic bristles 15, thereby assisting the plastic bristles 15 in capturing the fluff (the combing glass needle 163 is made of high-strength material, such as tempered glass, and will not break or be damaged when it contacts and rotates with the plastic bristles 15. Secondly, since the combing glass needle 163 is a hard object with a relatively smooth surface, it is not easy to absorb the fluff after contacting the plastic bristles 15. Moreover, under the action of the rotation of the combing glass needle 163, the centrifugal force generated by it can also throw out a small amount of absorbed fluff).

[0041] The wind flow after passing through the plastic bristles 15 will be discharged into each dust collecting bag 182 through the exhaust hopper 17 and each L-shaped tube 181. Under the interception effect of the dust collecting bag 182, the fluff and dust that are not intercepted by the plastic bristles 15 can be intercepted, and the purified air is discharged through the dust collecting bag 182.

[0042] After the controller 19 starts the belt drive mechanism 13, the spotlight 23 is started at the same time. When the belt drive mechanism 13 is working, it will drive the rotating disk 21 to rotate synchronously. When the light-transmitting hole 24 on the rotating disk 21 passes through the spotlight 23, the light emitted by the spotlight 23 will pass through the light-transmitting hole 24 to irradiate the photoelectric switch 25. After receiving the light signal, the photoelectric switch 25 will convert the light signal into an electrical signal and transmit it to the electronic counter 26. When the counting module of the electronic counter 26 receives a pulse electrical signal, it will increase the count by one. If the amount of lint entering each suction hopper 6 is small, each air inlet 83 moves downward a large distance. At this time, the air inlet 83 moves downward through the insulating rod 28 to drive the resistor sleeve 29 to move downward a large distance. Therefore, the length of the resistor sleeve 29 connected to the conductive ring 27 and the belt drive mechanism 13 is long. At this time, the resistance in the connection circuit of the resistor sleeve 29, the conductive ring 27 and the belt drive mechanism 13 becomes large. Therefore, the output power of the driving member of the belt drive mechanism 13 becomes small, so the speed of the belt drive mechanism 13 driving the rotating disk 21 becomes slower. At this time, , the frequency of the light signal emitted by the spotlight 23 received by the photoelectric switch 25 becomes lower, therefore, the counting speed of the electronic counter 26 becomes slower, and when there are more lint inside the air suction hopper 6, the downward movement distance of each air inlet tube 83 is small, and the connection circuit resistance of the resistor sleeve 29, the conductive ring 27 and the belt drive mechanism 13 is small, so the output power of the belt drive mechanism 13 becomes larger, and the rotation speed of the rotating disk 21 increases at this time, so the counting speed of the electronic counter 26 becomes faster, and when the electronic counter 26 reaches the set value (for example, reaches When the number of fluffs reaches 100,000, the electronic counter 26 will output an electrical signal to the controller 19. At this time, the alarm module inside the controller 19 will immediately sound an alarm to remind the personnel to remove the fluff inside the filter box 1 and the dust bag 182. By slowing down the counting speed of the electronic counter 26 when the amount of fluff is small and speeding up the counting speed of the electronic counter 26 when the amount of fluff is large, the amount of fluff trapped by the filter box 1 and the dust bag 182 can be roughly estimated, so that the personnel can be reminded to remove the trapped fluff in time.

[0043] Among them, each time the controller 19 receives a closing electrical signal from a pressure switch 202, it will control the output power of the fan 2 to reduce one level (reduced by 100 revolutions per minute). By reducing the rotation speed of the fan 2, it can be avoided that after the auxiliary air outlet scoop 11 is blocked, the air outlet aperture becomes smaller, resulting in excessive air pressure, which affects the winding effect of the plastic bristles 15 on the hair fluff.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
