Description

Technical Field

[0001] The present application relates to the technical field of cleaning impregnated paper particles, and in particular to a rubber-impregnated conveyor belt. Background Art

[0002] Impregnated paper is made by evenly infiltrating amino resin into base paper through the impregnation process, forming a finishing material with wear resistance, corrosion resistance and other properties. After the base paper is unwound, it is guided by the impregnation conveyor belt through the impregnation tank to complete the resin impregnation, and then enters the drying stage.

[0003] During the production of impregnated paper, if undissolved curing agent, release agent residue or aluminum oxide abrasive agglomeration is mixed into the resin glue during the preparation process, raised particles will be formed after impregnation; if the surface of the dipping tank, scraper or roller is not cleaned in time, the residual glue blocks or debris may adhere to the paper surface; the dust in the air of the production workshop settles before the paper dries and combines with the uncured resin to form particles. In addition, the uneven fibers of the base paper itself or impurities in the printing ink will also form particles on the surface of the paper.

[0004] At present, the treatment of particulate matter is mainly through manual identification of particle locations and local scraping, but the efficiency is low and it is easy to miss tiny particles. Improper force control during scraping may damage the surface resin of the impregnated paper, resulting in reduced wear resistance or scratches. When using a fixed scraper to remove excess glue on the surface, although it can reduce particle adhesion, it cannot distinguish between particles and normal glue layers, and may excessively scrape uncontaminated areas, destroying the uniformity of the resin.

The voltage difference between the two receiving electrodes is captured by the comparator. Since the single-sided particles cause the voltage of the electrodes on the same side to drop significantly, the specific position of the particles on the inner or outer side of the impregnated paper can be effectively distinguished. Combined with the independent control mechanism of the strip area, the horizontal precise positioning of the particles can be achieved.

[0017] 2. Based on the electrode group detection signal, the three-state comparator drives the electromagnets of different cleaning rollers through the NMOS / PMOS tube combination. When the inner side particles are detected, the comparator outputs a high level to turn on the NMOS, triggering the electromagnet of the cleaning roller to absorb the metal shaft, drive the telescopic tube to engage the transmission, and the adhesive gun contacts the contaminated point at the set phase angle to avoid excessive cleaning.

[0018] 3. The adhesive gun adopts a pressure shaft-liquid inlet linkage structure: when the electromagnetic sheet is energized, the gun shaft moves outward to connect the liquid inlet with the adhesive chamber, and the adhesive is squeezed by the pressure shaft and overflows from the liquid outlet; after power failure, the tension spring resets the gun shaft, and the rubber plug of the pressure shaft re-seals the liquid inlet. This mechanism ensures that the adhesive is released only at the moment of contact. In conjunction with the water-absorbing resin-abutment shaft extrusion structure of the cleaning gun, when the cleaning roller rotates to a specific angle, the abutment shaft triggers the gun barrel to drain water, and the water-soluble adhesive is immediately removed. This two-stage cleaning is controlled by the timing of the slide and the contact switch, so that the adhesive can be cleaned immediately after use to prevent secondary contamination.

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The embodiment of the present application discloses a rubber-impregnated conveyor belt, which comprises a transmission component for transmitting impregnated paper, a detection component for detecting particles on the surface of the impregnated paper, and a cleaning component for cleaning the particles.

[0027] The transmission assembly includes a number of horizontally rotating transmission rollers. After the impregnated paper is wound around the transmission rollers, it forms an S-shaped moving track along the vertical plane. After the impregnated paper contacts the transmission rollers from top to bottom or from bottom to top, it changes to the opposite movement direction.

[0028] In this embodiment, the transmission rollers include a transmission roller 1 and a transmission roller 2 5, and the transmission roller 1 is at a lower level than the transmission roller 2 5. After the impregnated paper moves from top to bottom and contacts the transmission roller 1, it changes direction and moves from bottom to top toward the transmission roller 2 5; after contacting the transmission roller 2 5, it changes direction again and moves from top to bottom.

[0029] The detection component includes several groups of electrode groups. The electrode group includes two electrode assemblies 2, and the electrode assembly 2 includes a transmitting electrode 3 and a receiving electrode 4 arranged opposite to each other. The transmitting electrode 3 and the receiving electrode 4 are arranged in parallel on both sides of the vertical section of the impregnated paper in the horizontal direction. The two groups of electrode assemblies 2 are arranged in opposite directions, that is, the transmitting electrodes 3 of the two groups of electrode assemblies 2 are arranged on both sides of the vertical section of the impregnated paper in the horizontal direction, and the two receiving electrodes 4 are arranged on both sides of the vertical section of the impregnated paper in the horizontal direction. Several groups of electrode groups are arranged in an array along the width direction of the impregnated paper; the impregnated paper is divided into several strip areas along its width direction, and each electrode group is arranged in the strip area.

[0030] The electrode group is connected to two motor electromagnets through a motor comparator and two motor relays. Specifically, the transmitting electrode 3 of the electrode assembly 2 is connected to the power supply, and the receiving electrode 4 is connected to the motor comparator through a measuring circuit; preferably, the motor comparator is a three-state output comparator. In the same electrode group, the receiving electrodes 4 in the two electrode assemblies 2 are respectively connected to the positive input and negative input of the motor comparator after being connected to the measuring circuit. The output end of the motor comparator is connected to the coils of motor relay 1 and motor relay 2 through MOS tubes; preferably, an NMOS tube is connected between the output end of the motor comparator and the coil of motor relay 1, and a PMOS tube is connected between the output end of the motor comparator and the coil of motor relay 2.

It should be noted that each electrode group is provided with motor relay 1 and motor relay 2, and several motor relays 1 are respectively connected to motor electromagnet 1, and several motor relays 2 are respectively connected to motor electromagnet 2.

[0031] Furthermore, a positive feedback resistor is connected between the motor comparator output terminal and the positive phase input terminal. A pull-down resistor is connected between the motor comparator output terminal and the ground; a pull-up resistor is connected between the motor comparator output terminal and the power supply; when the voltages of the positive phase input terminal and the negative phase input terminal are consistent, the output terminal voltage is forced to be pulled to the intermediate level by the pull-up resistor and the pull-down resistor, so that both the NMOS tube and the PMOS tube are cut off, and the motor relay 1 and the motor relay 2 are powered off. Preferably, the motor relay 1 and the motor relay 2 are respectively connected to independent power supplies; the positive pole of the independent power supply is connected to the positive pole of the motor electromagnet through the normally open contact of the motor relay, and the negative pole of the motor electromagnet is grounded.

[0032] The cleaning assembly includes at least two cleaning rollers, and the cleaning rollers and the driving rollers are rotatably arranged on the same vertical plane. In the present embodiment, the cleaning roller 1 6 is located above the driving roller 1 1, and the cleaning roller 2 7 is located below the driving roller 2 5; the cleaning roller 1 6 and the cleaning roller 2 7 have the same structure. The cleaning roller includes a roller 8, a roller shaft 9, and a motor 10 for driving the roller 8 to rotate. The roller shaft 9 is fixedly arranged, and the roller 8 is sleeved on the side of the roller shaft 9 and is rotatably connected to the roller shaft 9. A telescopic tube 11 is slidably connected to the end of the output shaft of the motor 10, and the telescopic tube 11 rotates synchronously with the output shaft of the motor 10. A connecting disk 12 is fixedly provided at one end of the telescopic tube 11 away from the motor 10, and a connecting disk 2 13 is fixedly provided on the end face of the roller 8, and the connecting disk 12 can be engaged with the connecting disk 2 13. Specifically, the end surface of the connection disk 12 has a plurality of wedge-shaped engaging teeth evenly distributed along its circumference, and the end surface of the connection disk 2 13 has a plurality of engaging grooves evenly distributed along its circumference. After the connection disk 12 contacts the connection disk 2 13, the connection disk 12 and the connection disk 2 13 engage with each other through the engagement of the engaging teeth and the engaging grooves.

[0033] A metal shaft 14 is rotatably arranged in the telescopic tube 11, and the metal shaft 14 penetrates the connection plate 12, and the telescopic tube 11 moves axially along the output shaft of the motor 10 following the metal shaft 14. The motor electromagnet 1 and the motor electromagnet 2 are respectively fixed to the ends of the roller shaft 9 of the two cleaning rollers; after the motor electromagnet 1 or the motor electromagnet 2 is energized, the metal shaft 14 is magnetically attracted to make the metal shaft 14 drive the telescopic tube 11 to move; after the metal shaft 14 is connected to the motor electromagnet 1 or the motor electromagnet 2, the telescopic tube 11 and the metal shaft 14 rotate relative to each other, and at the same time, the connection plate 12 is in contact with the connection plate 2 13.

[0034] Specifically, after a voltage difference appears at the two input ends of the motor comparator, the motor comparator outputs a high-level signal to the two motor relays according to the direction of the pressure difference; the motor relays receiving the high-level signal control the motor electromagnet to be energized; when the pressure difference at the two input ends of the motor comparator is close, the motor electromagnet is de-energized. After the motor electromagnet 1 or the motor electromagnet 2 is energized, the corresponding roller 8 is controlled to rotate.

[0035] In this embodiment, the surface of the impregnated paper in contact with the transmission roller 1 is regarded as the inner side, and the surface of the impregnated paper in contact with the transmission roller 2 5 is regarded as the outer side. The motor electromagnet 1 is arranged on the cleaning roller 1 6, and the motor electromagnet 2 is arranged on the cleaning roller 2 7. When particles appear on the inner side of the impregnated paper, the voltage value output by the electrode assembly close to the inner side of the impregnated paper is greater than the voltage value of the electrode assembly far from the inner side of the impregnated paper, and the motor comparator outputs a level signal to the motor relay 1 according to the pressure difference, and the motor relay 1 controls the motor electromagnet 1 to start according to the received level signal.

[0036] Furthermore, a motor timer is set between the MOS tube and the motor relay. After the high-level signal sent by the motor comparator is transmitted to the motor timer, the motor timer sends a low-level signal to the motor relay after the timing is completed, so that the motor electromagnet is powered off. The timing time of the motor timer is equal to the time it takes for the cleaning roller to rotate one circle, so that the roller shaft is separated from the motor output shaft after the cleaning roller rotates one circle. The motor timer is a 555 timer, and the output end of the motor comparator is connected to the TRIG pin of the 555 timer, the OUT pin of the 555 is connected to the gate of the MOS tube, and the drain of the MOS tube is connected to the motor relay coil.

[0037] Several groups of adhesive guns 15 and cleaning guns 16 are fixedly arranged around the roller 8; the several groups of adhesive guns 15 and cleaning guns 16 are evenly distributed around the roller 8 along the axial direction of the roller 8, and the angle between the adhesive guns 15 and the cleaning guns 16 located on the same radial direction of the roller 8 is 90°. The adhesive gun 15 includes a gun barrel 17 and a gun shaft 18 slidably arranged in the gun barrel 17. The gun barrel 17 is sequentially provided with a cleaning chamber 19, an adhesive chamber 20 and a control chamber 21, and the chambers are separated by a partition 22. The gun shaft 18 penetrates the partition 22 and is coaxially arranged with the gun barrel 17; the cleaning chamber 19 is located at the end away from the roller shaft 9; and the adhesive chamber 20 is provided with adhesive. A metal ring 32 is fixedly arranged at the end of the gun shaft 18 close to the roller shaft 9, and the metal ring 32 is located in the control chamber 21. An electromagnetic sheet is fixedly provided on the side of the partition plate 22 of the control chamber 21 and the adhesive chamber 20 near the roller shaft 9; when the electromagnetic sheet is energized, the gun shaft 18 is moved to the side away from the roller shaft 9 by magnetically attracting the metal ring 32, and the end of the gun shaft 18 extends out of the gun barrel 17 after the movement. A tension spring 23 is fixedly provided in the control chamber 21, and the end of the tension spring 23 is fixedly connected to the metal ring 32, which is used to drive the metal ring 32 and the gun shaft 18 to reset to the direction close to the roller shaft 9.

[0038] A pressure shaft 24 is coaxially arranged in the gun barrel 17; the pressure shaft 24 is fixedly connected to the gun barrel 17. The gun shaft 18 is a circular tube, and the pressure shaft 24 extends into the gun shaft 18 and is slidably connected to the gun shaft 18; a rubber plug is fixedly arranged at the end of the pressure shaft 24 away from the roller shaft 9. A strip-shaped liquid inlet hole 25 is opened on the circumference of the gun shaft 18, and the liquid inlet hole 25 is located in the adhesive chamber 20; a plurality of liquid outlet holes are opened at the end of the gun shaft 18 away from the roller shaft 9, and the adhesive entering the gun shaft 18 is attached to the end of the gun shaft 18 through the liquid outlet holes. Specifically, when the electromagnetic piece is powered off, the rubber plug is located between the liquid inlet hole 25 and the end of the gun shaft 18, and the liquid inlet hole 25 is blocked by the pressure shaft 24, so that the adhesive cannot enter the gun shaft 18. When the electromagnetic sheet is powered on, the gun shaft 18 moves toward the outside of the gun barrel 17, and the side wall of the liquid inlet hole 25 near the end of the gun shaft 18 moves toward the bottom of the rubber plug, so that a gap appears between the end of the rubber plug and the liquid inlet hole 25, and the adhesive enters the liquid inlet hole 25 through pressure and flows to the end of the gun shaft 18. When the electromagnetic sheet is powered off again, the gun shaft 18 is reset, and the liquid inlet hole 25 is restored to a closed state.

[0039] The inner circumference of the roller 8 is provided with several groups of contact switches respectively connected to the electromagnetic sheet, and the electromagnetic sheet is connected to the power supply through the contact switch. The outer circumference of the roller shaft 9 is provided with several slides 26 respectively used to trigger the contact switches. Several groups of contact switches and several slides 26 are respectively distributed along the axial direction of the roller 8 and the roller shaft 9. The longitudinal section of the slide 26 is arc-shaped. Preferably, the end of the contact switch is set to a rounded corner to facilitate the rotation process of the roller 8. The slide 26 presses the contact switch to put it in a pressed state. The outer circumference of the roller shaft 9 is provided with a slide groove 27 for accommodating the slide 26. The slide groove 27 is fixed with a glue gun electromagnet and a second tension spring; the side wall of the slide 26 is fixed with a metal sheet that can be magnetically attracted to the glue gun electromagnet. After the glue gun electromagnet is energized, the metal sheet is magnetically attracted to move the slide 26 to the outside of the slide groove 27; the second tension spring is fixed to the slide 26, and is used to drive the slide 26 to reset to the inside of the slide groove 27. After the slide plate 26 moves to the outside of the slide slot 27, the contact switch contacts the slide plate 26, making the electromagnetic plate conductive; otherwise, the contact switch is in an off state.

[0040] Specifically, the slide 26 is arranged in the horizontal direction and close to one side of the electrode group. When the adhesive gun electromagnet is energized, when the roller 8 rotates until the adhesive gun 15 is close to the horizontal state, the contact switch contacts the slide 26 to energize the electromagnet, and the gun shaft 18 extends out of the gun barrel 17 and contacts the surface of the impregnated paper, and the particles on the surface of the impregnated paper are adhered by the adhesive.

[0041] Specifically, in the initial state, the adhesive gun 15 is located below the cleaning roller. After the impregnated paper passes through the electrode group, if particulate matter is detected on the inner side of the impregnated paper, the cleaning roller 6 is triggered to rotate; the cleaning roller 6 rotates clockwise, so that the impregnated paper moving downward contacts the adhesive gun 15 rotating upward. When the adhesive gun 15 rotates to a horizontal state close to one side of the electrode group, the gun shaft 18 extends out of the gun barrel 17 and contacts the surface of the impregnated paper. By setting, when the impregnated paper moves from the electrode group to the horizontal position of the cleaning roller 6, the cleaning roller 6 rotates 90° clockwise. If particulate matter is detected on the outer side of the impregnated paper, the cleaning roller 27 is triggered to rotate, and the cleaning roller 27 rotates counterclockwise, and the impregnated paper moving upward contacts the adhesive gun 15 rotating downward. By setting, when the impregnated paper moves from the electrode group to the horizontal position of the cleaning roller 27, the cleaning roller 27 rotates 270° counterclockwise.

[0042] The two electrode assemblies 2 in the electrode group are connected to the adhesive gun electromagnet through the cleaning roller comparator and the adhesive gun relay. Specifically, after the receiving electrodes 4 of the two electrode assemblies 2 are connected to the measuring circuits, the two measuring circuits are connected to the input ends of the differential amplifier, the output ends of the differential amplifier are connected to the positive input end of the cleaning roller comparator, and the negative input end of the cleaning roller comparator is connected to the reference voltage; the output end of the cleaning roller comparator is connected to the adhesive gun relay coil, and the adhesive gun electromagnet is connected to the normally open contact of the adhesive gun relay. After particulate matter appears on the surface of the impregnated paper, a pressure difference appears between the two receiving electrodes 4, the input voltage of the cleaning roller comparator is higher than the reference voltage, the cleaning roller comparator outputs a high level to the adhesive gun relay, and the adhesive gun relay controls the adhesive gun electromagnet to be energized.

[0043] Preferably, a transistor is installed between the cleaning roller comparator and the adhesive gun relay; the output end of the cleaning roller comparator is connected to the base of the NPN transistor, the collector of the NPN transistor is connected to one end of the adhesive gun relay coil, and the other end of the adhesive gun relay coil is connected to the power supply; the emitter of the NPN transistor is grounded; the adhesive gun relay coil is connected in reverse parallel with a freewheeling diode. An adhesive gun timer is installed between the cleaning roller comparator and the adhesive gun relay. After the cleaning roller comparator outputs a high level, the adhesive gun timer starts timing. After the adhesive gun timer ends timing, a high level signal is sent to the adhesive gun relay, and the adhesive gun relay controls the adhesive gun electromagnet to energize. The output end of the adhesive gun comparator is connected to the TRIG pin of the 555 timer through an RC filter circuit; the OUT pin of the 555 timer is connected to the base of the NPN transistor through an inverter; the collector of the NPN transistor is connected to the adhesive gun relay coil.

[0045] The cleaning gun 16 includes a gun barrel 28 and a water-absorbing resin filled in the gun barrel 28. The gun barrel 28 is filled with liquid water, so that the water-absorbing resin is in a state of more than half saturation. The end of the gun barrel 28 close to the roller shaft 9 is slidably connected with an abutment sheet; the end of the gun barrel 28 away from the roller shaft 9 is provided with a plurality of water outlet holes. After the abutment sheet moves to the inside of the gun barrel 28, the liquid water is applied to the end of the gun barrel 28 from the water outlet pipe by squeezing the water-absorbing resin. The outer peripheral surface of the roller shaft 9 is slidably provided with a plurality of abutment shafts 29, and the abutment shafts 29 and the sliding sheet 26 are arranged on both sides of the roller shaft 9 oppositely. The end of the abutment shaft 29 is set to a rounded corner. When the cleaning gun 16 rotates to a horizontal state away from the electrode group, the abutment sheet contacts the abutment shaft 29, and at the same time, the end of the cleaning gun 16 contacts the impregnated paper. The abutment shaft 29 removes the adhesive remaining on the surface of the impregnated paper by pressing the abutment sheet.

[0046] The outer peripheral surface of the roller shaft 9 is uniformly provided with a plurality of abutment grooves 30 along its axial direction, and the abutment shaft 29 is slidably arranged in the abutment groove 30. A cleaning gun electromagnet is fixed in the abutment groove 30, and a metal sheet that can be magnetically attracted to the cleaning gun electromagnet is fixed on the side wall of the abutment shaft 29; when the cleaning gun electromagnet is energized, the abutment shaft 29 moves toward the outside of the abutment groove 30 by magnetically attracting the metal sheet. A tension spring 3 is fixed in the abutment groove 30, and the tension spring 3 is fixed to the abutment shaft 29, and is used to drive the abutment shaft 29 to reset to the inside of the abutment groove 30.

[0047] Specifically, if particulate matter is detected on the inner side of the impregnated paper, the impregnated paper contacts the adhesive gun 15 of the cleaning roller 16, moves from bottom to top after passing through the transmission roller 1, and contacts the cleaning gun 16 rotating from top to bottom counterclockwise. When the impregnated paper moves from the electrode group to the level of the cleaning roller 16 away from the electrode group, the cleaning roller 16 rotates 180°. If particulate matter is detected on the outer side of the impregnated paper, the impregnated paper contacts the adhesive gun 15 of the cleaning roller 27, moves from top to bottom through the transmission roller 25, and contacts the cleaning gun 16 rotating from bottom to top clockwise. When the impregnated paper moves from the electrode group to the level of the cleaning roller 27 away from the electrode group, the cleaning roller 27 rotates 360°.

[0050] It should be noted that the impregnated paper is divided into a plurality of strip regions along its width direction, and each cleaning gun 16 and abutting shaft 29 are arranged in the strip region. The electrode group and the cleaning gun electromagnet located in the same strip region are connected. The cleaning gun electromagnets on the cleaning roller 1 6 and the cleaning roller 2 7 located in the same strip region are connected in series and then connected to the normally open contact of the cleaning gun relay.
