Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing and transportation equipment, and in particular relates to a cargo conveying type air shower room. Background Art

[0002] The cargo conveyor air shower is a device specially used for air shower purification of cargo or goods. When the cargo is placed on the conveyor belt and enters the air shower, a high-speed clean airflow will be blown out from the inside of the air shower. These airflows will blow toward the surface of the cargo from different directions to remove dust, particles and other pollutants that may be on the surface of the cargo. The high-speed airflow uses strong impact force and airflow shear force to peel off the pollutants from the surface of the cargo and bring them into the air filter for filtration, thereby ensuring that the blown airflow always remains clean.

[0003] When goods are conveyed in the air shower room, the friction between the goods and the conveyor belt will cause static electricity to accumulate between the two. Static electricity will cause more dust and tiny particles to be adsorbed on the surface of the goods. During the air shower process, these dust adsorbed by static electricity are difficult to be easily blown away by the air flow of the air shower, thereby reducing the cleaning effect of the air shower. In addition, static electricity will interfere with the air flow inside the air shower room. The static electricity field will produce a certain attraction or repulsion force on the air flow of the air shower, causing the direction and speed of the air flow to change, resulting in uneven air showering, and then making some parts of the goods unable to get sufficient air showering, affecting the overall air shower quality. In order to reduce the generation of static electricity, the surface of the conveyor belts currently used is relatively smooth, and the smooth surface of the conveyor belts and the goods are smooth. The friction coefficient is relatively low. During the transportation of goods, friction is the main cause of static electricity. A lower friction coefficient means less static electricity generated by friction, thereby reducing the possibility of static electricity adsorbing dust. The smooth surface can make the contact between the goods and the conveyor belt more uniform, which helps to evenly distribute the charge and reduce the generation of static electricity. However, blindly improving the surface smoothness of the conveyor belt can reduce the generation of static electricity, but it will affect the transportation of goods. When the weight of the goods is heavy, greater friction is needed to prevent the goods from sliding. If the friction coefficient of the conveyor belt is too small, the goods will slip on the conveyor belt, affecting the transportation efficiency, and even causing damage to the goods or causing safety accidents.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the air shower room main body, conveying mechanism, cargo positioning and sorting mechanism, and conveying alternating triggering mechanism, the cargo can be accurately placed on the conveying mechanism before being conveyed. Accurate positioning can avoid collision, squeezing or falling of the cargo during the conveying process, thereby reducing the risk of cargo damage and improving the quality and efficiency of cargo handling.

[0014] 2. Through the transmission friction coefficient control mechanism, weighing feedback control mechanism and transmission mechanism, the weight of the goods to be transmitted can be quickly detected, and the friction coefficient between the transmission mechanism and the goods can be adjusted based on the weight of the goods. When the goods are heavy, the friction coefficient is increased to improve the friction resistance between the transmission mechanism and the goods to ensure the stability of the goods during the transmission process. When the goods are light, the friction coefficient is automatically reduced. A lower friction coefficient can reduce the static electricity generated by friction, reduce the possibility of static electricity adsorbing dust, and avoid static electricity causing the surface of the goods to adsorb more dust and tiny particles, which are difficult to be washed away by wind. The airflow is easily blown away, thereby reducing the problem of air shower cleaning effect, and the transmission speed and airflow speed can be automatically adjusted based on the weight of the goods. The heavier the goods, the slower the transmission speed and airflow speed. This is because the heavier the goods, the greater the pressure on the conveyor belt, which will aggravate the wear of the conveyor belt when running quickly. Reducing the transmission speed can reduce the friction frequency and friction strength between the conveyor belt and the goods, thereby extending the service life of the conveyor belt. When the transmission speed slows down, the airflow speed is reduced simultaneously to avoid excessive blowing and reduce unnecessary energy waste. When the transmission speed is fast, the airflow speed is increased to ensure that the goods can be sufficiently blown in a shorter time.

[0015] 3. The static electricity extraction mechanism, static electricity extraction trigger control mechanism and weighing feedback control mechanism are set up to realize the static electricity extraction of the conveying mechanism at intervals. Compared with the traditional method of always grounding the conveying mechanism to remove static electricity, the grounding wire is in continuous contact with the conveyor belt, which interferes with the operation of the conveyor belt and hinders its smooth operation, causing the goods to shake or shift during the transmission process, thereby affecting the air shower effect. The frequency of static electricity removal can be automatically adjusted based on the friction coefficient of the conveyor belt. When the friction coefficient of the conveying mechanism needs to be set higher, the frequency of static electricity removal is higher, thereby automatically matching the rate of static electricity generation and avoiding the impact of static electricity accumulation on air shower work.

[0026] The PLC controller 11 is fixedly mounted on the outer wall of the air shower room body 1, and is electrically connected to the conveying mechanism 2, the electrostatic derivation mechanism 3, the conveying friction coefficient regulating mechanism 4, the cargo positioning and sorting mechanism 5, the weighing feedback regulating mechanism 6, the conveying alternating triggering mechanism 7 and the electrostatic derivation triggering control mechanism 8 respectively.

[0027] The operating principle of the present invention is now described as follows: first, the cleaned goods to be transported are placed on the input end of the transport mechanism 2, the PLC controller 11 controls the electric telescopic rod 52 to start, the electric telescopic rod 52 pushes the clamping shell 54 to move downward, so that the two side clamping plates 58 move to the two sides of the goods, and the PLC controller 11 controls the double-axis motor 55 to operate, the double-axis motor 55 drives the two rotating screws 56 to rotate synchronously, and the threaded sleeve effect of the rotating screw 56 and the moving seat 57 makes the moving seat 57 drive the two side clamping plates 58 to move toward each other, so that the two side clamping plates 58 clamp and limit the goods. In the process of clamping, the tilted goods can be neatly placed, and accurate positioning can prevent the goods from colliding, squeezing or falling during the transportation process, thereby reducing the risk of damage to the goods and improving the quality and efficiency of goods processing; The PLC controller 11 then controls the electric telescopic rod 52 to drive the push-pull plate 53 to move upward, and the push-pull plate 53 drives the goods to move upward synchronously through the pulling elastic force of the pulling spring 511. The weight feedback of the goods acts on the clamping shell 54 to overcome the elastic force of the pulling spring 511. Specifically, when the weight of the goods is greater, the pulling spring 511 needs to produce a greater deformation and provide a greater elastic force to realize the synchronous lifting action of the push-pull plate 53 on the clamping shell 54, thereby making the clamping shell 54 have a greater displacement distance relative to the push-pull plate 53. In the process of driving the push-pull plate 53 to move upward by the electric telescopic rod 52, the PLC controller 11 controls The second electric slide rail 61 drives the regulating housing 62 to move, thereby making the transmission gear 610 mesh with the transmission rack 611. When lifting goods, the goods drive the clamping housing 54 to move relative to the push-pull plate 53, thereby driving the transmission rack 611 to move relative to the push-pull plate 53. The displacement of the transmission rack 611 drives the transmission gear 610 to rotate, and then cooperates with the speed increasing gear box 69 to drive the transmission screw 63 to rotate. Through the threaded sleeve effect of the transmission screw 63 and the transmission seat 64, the transmission seat 64 moves relatively in the regulating housing 62, driving the regulating conductive contact piece 66 to slide on the regulating resistor rod 65, and driving the trigger round head 68. Synchronous movement, when the weight of the goods is greater, the displacement of the transmission rack 611 relative to the transmission gear 610 is greater, and then the movement distance of the transmission seat 64 is greater, so that the distance that the regulating conductive contact 66 slides on the regulating resistor rod 65 is greater, and the access resistance value of the regulating resistor rod 65 is smaller, and the trigger round head 68 can press and act on the regulating switch 67 at the rear side. After the weighing detection is completed, the PLC controller 11 first controls the second electric slide rail 61 to drive the regulating shell 62 to move backward, so that the transmission gear 610 is disengaged from the meshing connection with the transmission rack 611, and the PLC controller 11 then controls the electric telescopic The rod 52 drives the goods to move downward, so that the goods are placed on the conveying mechanism 2 for conveying. After the goods are placed on the conveyor belt 24, the PLC controller 11 controls the double-axis motor 55 to drive in the reverse direction, so that the two side clamps 58 are released from clamping and fixing the goods, and then drives the electric telescopic rod 52 to drive the clamping shell 54 and the side clamps 58 to move upward, so that the clamping shell 54 and the side clamps 58 are retracted into the outer expansion shell 51, and the PLC controller 11 controls the first electric slide rail 512 to move, and the first electric slide rail 512 drives the sealing baffle 513 to move, so that the sealing baffle 513 is blocked at the connection between the outer expansion shell 51 and the air shower room body 1; The driving motor 25 drives the multiple conveying rollers 23 to rotate, and the conveying rollers 23 drive the conveying belts 24 to move, and the conveying belts 24 are used to realize fast and stable conveying of the goods, and the conveying mechanism 2 is provided with two groups, each group of conveying mechanism 2 includes two conveying belts 24, and the two groups of conveying mechanism 2 can realize the alternating conveying drive of the goods under the action of the electric lifting rod 21, so that the supporting part at the bottom of the goods will not be unable to be cleaned in place due to the continuous contact with the conveying belts 24, so that the cleaning airflow sprayed by the air nozzle 9 can act more comprehensively on the outer surface of the goods, providing more The air shower cleaning work is efficient and comprehensive. When the goods are conveyed, the PLC controller 11 controls the servo motor 73 to operate. The servo motor 73 drives the reciprocating screw 72 to rotate. The threaded sleeve of the reciprocating screw 72 and the pressing plate 74 makes the pressing plate 74 reciprocate in the trigger shell 71. When the pressing plate 74 presses on the first trigger switch 75, the PLC controller 11 controls the action of one group of the conveying mechanism 2. When the pressing plate 74 presses on the second trigger switch 76, the PLC controller 11 controls the action of the other group of the conveying mechanism 2. When the cargo is heavier and the trigger head 68 presses on the regulating switch 67 at the rear side, the PLC controller 11 receives the feedback signal of the regulating switch 67 and controls the drive motor 25 to reduce the conveying speed of the cargo at a slower driving speed, and at the same time reduces the flow rate of the gas sprayed by the air nozzle 9, thereby extending the service life of the conveyor belt 24, avoiding excessive blowing, and reducing unnecessary energy waste. The regulating switch 67 also controls the rotation speed of the servo motor 73. When the regulating switch 67 at the rear side is pressed and triggered, the rotation speed of the servo motor 73 is synchronously reduced, so that the interval between the pressing and triggering of the first trigger switch 75 and the second trigger switch 76 is longer, and the frequency of alternating conveying of the cargo is synchronously adjusted in accordance with the conveying speed. The regulating conductive contact 66 and the regulating resistor rod 65 are connected in series to the power supply circuit of the thrust electromagnetic plate 47. When the thrust electromagnetic plate 47 is energized, it generates the same magnetism as the thrust permanent magnet plate 46, thereby driving the force-bearing plate 42 to overcome the elastic force of the return spring 45 along the guide slide rod 44 and push the protective protrusion outward. Specifically, when the weight of the goods is greater, the access resistance of the regulating resistor rod 65 is smaller, thereby making the power supply current of the thrust electromagnetic plate 47 greater, the thrust electromagnetic plate 47 generates greater magnetism, and thereby making the anti-skid protrusion 43 move outward a greater distance. The anti-skid protrusion 43 will squeeze the conveyor belt 24 during its operation, causing local deformation and bulge on the surface of the conveyor belt 24. In this way, when When the goods are placed on the conveyor belt 24, the contact area and contact pressure between the goods and the conveyor belt 24 will change, thereby changing the friction coefficient. When the outward movement distance of the anti-skid protrusion 43 increases, the embedding depth between the goods and the conveyor belt 24 is greater, and the friction force will increase accordingly. The higher protrusion can better grasp the goods and prevent the goods from sliding on the conveyor belt 24, thereby ensuring the stability of the goods during the transmission process. [The height of the anti-skid protrusion 43 is relatively small relative to the size of the entire goods, and plays the role of an anti-skid protrusion. Therefore, the goods will not be suspended too much, and the outer surface packaging of the goods is mostly deformable, so it will not cause the goods to shake during the transmission process.] When the conveying mechanism 2 is working, the PLC controller 11 controls the reduction motor 83 to move synchronously. The reduction motor 83 drives the intermediate shaft 82 to drive the arc-shaped pressing block 85 to move in the control round shell 81. When the arc-shaped pressing block 85 presses on the start switch 84, the PLC controller 11 controls the micro electric push rod 31 to push the U-shaped insulating plate 32 upward, so that the conductive roller 33 contacts the surface of the conveyor belt 24. The conductive roller 33 rotates synchronously with the movement of the conveyor belt 24. The conductive block quickly discharges the static electricity accumulated on the surface of the conveyor belt 24, and discharges the static electricity through the arc-shaped conductive block 34 and the grounding wire 35. The contact time between the electric roller 33 and the conveyor belt 24 depends on the running speed of the conveyor belt 24. After the electric roller 33 is in full contact with the surface of the conveyor belt 24, the PLC controller 11 controls the micro electric push rod 31 to drive the electric roller 33 to move downward, so that the electric roller 33 is out of contact with the conveyor belt 24. This not only realizes the static electricity discharge, but also avoids the grounding wire 35 from being in continuous contact with the conveyor belt 24 to interfere with the operation of the conveyor belt 24, hindering its smooth operation, causing the goods to shake or deviate during the transmission process, thereby affecting the air shower effect. In addition, the regulating conductive contact 66 and the regulating resistor rod 65 are also connected in series to the power supply circuit of the reduction motor 83. The reduction motor 83 is a DC motor. When the cargo is heavier, the resistance value of the regulating resistor rod 65 becomes smaller. At this time, the power supply current of the reduction motor 83 increases synchronously, so that the speed of the reduction motor 83 increases, thereby shortening the interval time of the arc-shaped pressing block 85 pressing on the start switch 84, and increasing the working frequency of the electrostatic extraction work. Because the heavier the cargo, the higher the friction coefficient of the conveyor belt 24, the more likely it is to cause the problem of static electricity accumulation. At this time, increasing the frequency of static electricity extraction can automatically match this situation, ensuring that static electricity can be extracted more promptly, and avoiding the impact of static electricity accumulation on the air shower work.
