Description

Technical Field

[0001] The invention relates to the technical field of waste conveying, in particular to a magnetic waste conveyor. Background Art

[0002] In stamping production, after the mold is completed, the cut corners of the raw material will form waste, and the waste will fall directly on the lower plate of the mold. However, when the waste accumulates to a certain amount, it is easy to cause the blanking hole of the mold to be blocked. If the punch press is turned off and the waste is removed manually, it will greatly increase the labor intensity of the operator and affect work efficiency. In addition, stamping after the waste is accumulated will also affect the health of the operator. Therefore, a conveyor is needed to transport the waste.

[0003] After searching, Chinese patent number CN213893994U discloses a magnetic material conveyor. Although multiple strong magnets are evenly distributed under the conveyor belt, the magnetic waste can be driven to move to the output end of the belt by its own magnetic attraction, thereby stably transporting the magnetic metal waste and avoiding the metal waste from getting stuck inside the machine body, causing the machine body to have a transportation failure, but it uses strong magnets to absorb the magnetic waste, so that the adsorption force between the magnetic waste and the belt is constant. When the belt speed is fast, the magnetic waste is easily separated from the belt under the influence of acceleration and inertia, and the expected adsorption effect cannot be achieved. At the same time, the inclination of the belt When the inclination angle increases, the supporting force of the belt on the magnetic waste decreases, and at the same time, the positive pressure of the magnetic waste on the belt decreases, which reduces the friction force on the magnetic waste. If the magnetic waste and the belt need to be kept relatively still, the magnetic adsorption force needs to be increased. The adsorption force of the strong magnet is constant, and there is a belt in the middle, so that the conveyor cannot adapt to the transportation of magnetic waste in the above two situations. The purpose of using a magnetic conveyor is to reduce the floor space of the conveyor while avoiding material jams, and to speed up the conveying efficiency, to avoid the scattering of magnetic waste, and to meet production to the greatest extent. Therefore, it is necessary to consider the above two situations. Summary of the invention

[0014] Adopting the above technical solution: Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention increases the output power of the motor so that the motor speeds up the rotation speeds of the first active roller and the second active roller, and repeats the above process to speed up the rotation speed of the conveyor belt. At the same time, the second active roller can speed up the rotation of the magnetic ring through the transmission shaft, so that the efficiency of the magnetic ring cutting the magnetic flux lines is improved, thereby increasing the induced current, indirectly increasing the direct current in the second coil, and enhancing the induced magnetic field generated by the second coil, thereby improving the magnetism of the conveyor belt in contact with the magnetic core, increasing the adsorption force of the conveyor belt on the magnetic waste, and making the rotation speed of the conveyor belt proportional to the adsorption force of the magnetic waste, thereby preventing the magnetic waste from being separated from the conveyor belt under the influence of acceleration and inertia, and achieving the expected adsorption effect.

[0016] 2.

[0017] 3. The present invention drives the first active roller and the second active roller to rotate by an electric motor. When the first active roller rotates, the first crawler on the first active roller drives the driven roller to rotate, so that the driven roller drives the sprocket to rotate through the active roller, thereby rotating the chain between the sprockets, so that the conveyor belt on the chain moves. When the second active roller rotates, the second active roller drives the sub-roller to revolve through the second crawler, so that the transmission roller on the sub-roller rotates, thereby rotating the transmission shaft on the transmission roller, so that the transmission shaft drives the magnetic ring to rotate around the first coil, thereby causing the first coil to cut the magnetic flux lines, so that An induced current is generated in the first coil. After the induced current is generated, it is transmitted to the rectifier through a wire. The rectifier then outputs direct current, and the direct current is transmitted to the pressure device through a connecting bridge. The pressure device increases the voltage of the direct current and finally introduces it into the second coil, so that the spiral second coil generates an induced magnetic field. Finally, the conveyor belt is magnetized through the magnetic core, so that the conveyor belt can absorb magnetic waste. In summary, the conveyor belt can absorb and transport magnetic waste. At the same time, the conveyor belt is made of stainless steel plate, and the traditional rubber belt is abandoned, which can prevent the conveyor belt from being scratched by the product and avoid abnormal situations such as material jamming.

At the same time, the second active roller 14 can accelerate the rotation of the magnetic ring 33 through the transmission shaft 32, so that the efficiency of the magnetic ring 33 cutting the magnetic flux lines is improved, thereby increasing the induced current, indirectly increasing the direct current in the second coil 48, and enhancing the induced magnetic field generated by the second coil 48, thereby improving the magnetism of the conveyor belt 18 in contact with the magnetic core 49, thereby increasing the adsorption force of the conveyor belt 18 on the magnetic waste, and making the speed of the conveyor belt 18 proportional to the adsorption force of the magnetic waste, thereby avoiding the magnetic waste from being separated from the conveyor belt 18 under the influence of acceleration and inertia, and achieving the expected adsorption effect.

[0034] Example 2

[0035] See also Figure 1-Figure 8 The present invention provides a technical solution: a magnetic conveyor for waste materials, wherein one end of a push rod 22 is fixedly connected to the side wall of a cross bar 6, and a first set of rods 23 is slidably sleeved on the other end of the push rod 22, and one end of a connecting pipe 24 is connected to the end surface of the first set of rods 23, and the other end of the connecting pipe 24 is connected to the second set of rods 25, and a first pull rod 26 is slidably sleeved in the second set of rods 25, and one end of a connecting block 27 is fixedly connected to the end surface of the first pull rod 26, and a second pull rod 28 is fixedly connected to the other end of the connecting block 27, and a third set of rods 29 is slidably sleeved on the outer surface of the second pull rod 28, and one end of a conduit 30 is connected to the end surface of the third set of rods 29, and a cavity ring 41 is fixedly connected to the other end of the conduit 30, and an airtight cavity 36 is opened in the side wall of a driving roller 34, and the airtight cavity 36 is connected to the cavity ring 41, and a support rod 37 is slidably sleeved in the airtight cavity 36, and the end of the support rod 37 is fixedly connected to a sliding shaft 38.

[0036] See also Figure 5 , Figure 7 and Figure 8 The first set of rods 23 is fixedly connected to the vertical rod 7, the second set of rods 25 and the third set of rods 29 are both fixedly connected to the first set of rods 23, a plurality of airtight chambers 36 are provided, and the plurality of airtight chambers 36 correspond one to one to the plurality of sub-rollers 39.

[0037] See also Figure 5 and Figure 8 The push rod 22, the first pull rod 26, the second pull rod 28 and the support rod 37 are all fixedly connected with pistons.

[0038] Specifically, in the process of increasing the inclination angle of the conveyor belt 18, the screws and the positioning bolts 9 are rotated to release the fixation of the slider 5 and the slider 3, and the telescopic rod 8 can be further inserted into the cross bar 6. At this time, the slider 3 is pushed to rotate toward the base 1, so that the inclination angle of the slider 3 increases, thereby reducing the floor space of the conveyor. In the above process, the vertical rod 7 is always in contact with the ground. When the slider 3 becomes steeper, the horizontal distance between the vertical rod 7 and the cross bar 6 is shortened, so that the telescopic rod 8 is inserted into the cross bar 6. At the same time, the distance between the slider 5 on the cross bar 6 and the slider 5 on the vertical rod 7 is shortened, so that the top rod 22 on the cross bar 6 is inserted into the first set of rods 23, so that the air in the first set of rods 23 is compressed, and the compressed air is guided to the first set of rods 23 through the connecting pipe 24. The connecting block 27 is inserted into the second rod 25, so that the first pull rod 26 in the second rod 25 extends out and pushes the connecting block 27 to move, so that the connecting block 27 drives the second pull rod 28 to extend the third rod 29, so that the third rod 29 absorbs the air in the cavity ring 41 through the conduit 30, and the cavity ring 41 is connected with the airtight cavity 36, so that the third rod 29 absorbs the air in the airtight cavity 36, and then the support rod 37 in the airtight cavity 36 retracts, so that the sliding shaft 38 and the sub-roller 39 on the support rod 37 retract into the groove 35, so that the effective radius of the sub-roller 39 is reduced, that is, the revolution radius is reduced, and the linear speed of the sub-roller 39 driven by the second active roller 14 to revolve through the second crawler 40 is constant. According to the formula It can be seen that v is constant, r decreases, and w increases, thereby increasing the angular velocity of the transmission roller 34 driven by the sub-roller 39, increasing the rotation speed of the transmission shaft 32 on the transmission roller 34, and increasing the rotation speed of the magnetic ring 33 on the transmission shaft 32. It can be seen from the above that the magnetism of the conveyor belt 18 is indirectly improved, and the adsorption force of the conveyor belt 18 on the magnetic waste is increased, that is, the greater the inclination angle of the conveyor belt 18, the greater the adsorption force of the conveyor belt 18 on the magnetic waste, so that the magnetic waste can continue to remain relatively still with the conveyor belt 18, which can avoid material jamming while reducing the floor space of the conveyor, speeding up the transportation efficiency, avoiding the scattering of magnetic waste, and meeting the production to the greatest extent.

[0041] See also Figure 1 and Figure 2 The chain 21 is fixedly connected to the inner surface of the conveyor belt 18, the conveyor belt 18 is made of stainless steel plate, and the conveyor belt 18 is slidably connected to the base 1 and the inner side wall of the slide seat 3, and the slider 5 is fixed to the slide seat 3 by screws.

[0042] See also Figure 2-Figure 4 The first active roller 13 and the driven roller 16 are both located in the sealing sleeve 11, the second active roller 14 is rotatably connected to the side wall of the sealing sleeve 11, the transmission roller 34 is rotatably connected to the side wall of the sealing sleeve 11, the transmission shaft 32 passes through the sealing sleeve 11, the active roller 17 is rotatably connected to the inner wall of the slide seat 3, and the driven roller 19 is rotatably connected to the inner wall of the base 1.

[0043] Specifically, in the process of conveying magnetic waste, the conveyor is moved to a designated position and the motor 12 is started, so that the motor 12 drives the first driving roller 13 and the second driving roller 14 to rotate. When the first driving roller 13 rotates, the first crawler 15 on the first driving roller 13 drives the driven roller 16 to rotate, so that the driven roller 16 drives the sprocket 20 to rotate through the driving roller 17, so that the chain 21 between the sprockets 20 rotates, so that the conveyor belt 18 on the chain 21 moves, and when the second driving roller 14 rotates, the second driving roller 14 drives the sub-roller 39 to revolve through the second crawler 40, so that the transmission roller 34 on the sub-roller 39 rotates, so that the transmission shaft 32 on the transmission roller 34 rotates, so that the transmission shaft 32 drives the magnetic ring 33 around The first coil 43 rotates, so that the first coil 43 cuts the magnetic flux lines, so that an induced current is generated in the first coil 43. After the induced current is generated, the induced current is transmitted to the rectifier 45 through the wire 44, and then the rectifier 45 outputs direct current, and transmits the direct current to the pressure booster 47 through the connecting bridge 46. The pressure booster 47 increases the voltage of the direct current and finally introduces it into the second coil 48, so that the spiral second coil 48 generates an induced magnetic field, and finally the conveyor belt 18 is magnetized through the magnetic core 49, so that the conveyor belt 18 can absorb magnetic waste. In summary, the conveyor belt 18 can absorb and transport magnetic waste. At the same time, the conveyor belt 18 is made of stainless steel iron plate, and the traditional rubber belt is abandoned, which can prevent the conveyor belt 18 from being scratched by the product and avoid abnormal situations such as jamming.

[0044] The working principle and use process of the present invention are as follows: when it is necessary to convey magnetic waste, the conveyor is moved to a designated position and the motor 12 is started, so that the motor 12 drives the first active roller 13 and the second active roller 14 to rotate. When the first active roller 13 rotates, the first crawler 15 on the first active roller 13 drives the driven roller 16 to rotate, so that the driven roller 16 drives the sprocket 20 to rotate through the active roller 17, thereby rotating the chain 21 between the sprockets 20, so that the conveyor belt 18 on the chain 21 moves, and when the second active roller 14 rotates, the second active roller 14 drives the sub-roller 39 to revolve through the second crawler 40, so that the transmission roller 34 on the sub-roller 39 rotates, thereby causing the transmission shaft 32 on the transmission roller 34 to rotate, so that the transmission shaft 32 drives the magnetic ring 33 rotates around the first coil 43, so that the first coil 43 cuts the magnetic flux lines, so that an induced current is generated in the first coil 43. After the induced current is generated, the induced current is transmitted to the rectifier 45 through the wire 44, and then the rectifier 45 outputs direct current, and transmits the direct current to the pressure booster 47 through the connecting bridge 46. The voltage of the direct current is increased by the pressure booster 47 and finally introduced into the second coil 48, so that the spiral second coil 48 generates an induced magnetic field, and finally the conveyor belt 18 is magnetized through the magnetic core 49, so that the conveyor belt 18 can absorb the magnetic waste. In summary, the conveyor belt 18 can absorb and transport the magnetic waste. At the same time, the conveyor belt 18 is made of stainless steel iron plate, and the traditional rubber belt is abandoned, which can prevent the conveyor belt 18 from being scratched by the product and avoid abnormal situations such as material jamming.

[0045] When it is necessary to speed up the speed of the conveyor belt 18, the output power of the motor 12 is increased, so that the motor 12 speeds up the speeds of the first active roller 13 and the second active roller 14, and the above process is repeated to speed up the speed of the conveyor belt 18. At the same time, the second active roller 14 can speed up the rotation of the magnetic ring 33 through the transmission shaft 32, so that the efficiency of the magnetic ring 33 cutting the magnetic flux lines is improved, thereby increasing the induced current, indirectly increasing the direct current in the second coil 48, and enhancing the induced magnetic field generated by the second coil 48, thereby improving the magnetism of the conveyor belt 18 in contact with the magnetic core 49, thereby increasing the adsorption force of the conveyor belt 18 on the magnetic waste, and making the speed of the conveyor belt 18 proportional to the adsorption force of the magnetic waste, so as to avoid the magnetic waste from being separated from the conveyor belt 18 under the influence of acceleration and inertia, and achieve the expected adsorption effect;

[0046] When it is necessary to reduce the floor space of the conveyor, the screws and the positioning bolts 9 are turned to release the fixation of the slider 5 and the slider 3. At the same time, the telescopic rod 8 can be further inserted into the cross bar 6. At this time, the slider 3 is pushed to rotate toward the base 1, so that the inclination angle of the slider 3 increases, thereby reducing the floor space of the conveyor. In the above process, the vertical rod 7 is always in contact with the ground. When the slider 3 becomes steeper, the horizontal distance between the vertical rod 7 and the cross bar 6 is shortened, so that the telescopic rod 8 is inserted into the cross bar 6. At the same time, the distance between the slider 5 on the cross bar 6 and the slider 5 on the vertical rod 7 is shortened, so that the top rod 22 on the cross bar 6 is inserted into the first set of rods 23, so that the air in the first set of rods 23 is compressed, and the compressed air is introduced into the first set of rods 23 through the connecting pipe 24. The second set of rods 25, thereby making the first pull rod 26 in the second set of rods 25 extend and push the connecting block 27 to move, so that the connecting block 27 drives the second pull rod 28 to extend the third set of rods 29, so that the third set of rods 29 absorbs the air in the cavity ring 41 through the conduit 30, and the cavity ring 41 is connected with the airtight cavity 36, so that the third set of rods 29 absorbs the air in the airtight cavity 36, and then the support rod 37 in the airtight cavity 36 retracts, so that the sliding shaft 38 and the sub-roller 39 on the support rod 37 retract into the groove 35, so that the effective radius of the sub-roller 39 is reduced, that is, the revolution radius is reduced, and the second active roller 14 drives the sub-roller 39 to revolve through the second crawler 40 at a constant linear speed. According to the formula It can be seen that v is constant, r decreases, and w increases, thereby increasing the angular velocity of the transmission roller 34 driven by the sub-roller 39, increasing the rotation speed of the transmission shaft 32 on the transmission roller 34, and increasing the rotation speed of the magnetic ring 33 on the transmission shaft 32. It can be seen from the above that the magnetism of the conveyor belt 18 is indirectly improved, and the adsorption force of the conveyor belt 18 on the magnetic waste is increased, that is, the greater the inclination angle of the conveyor belt 18, the greater the adsorption force of the conveyor belt 18 on the magnetic waste, so that the magnetic waste can continue to remain relatively still with the conveyor belt 18, which can avoid material jamming while reducing the floor space of the conveyor and speeding up the conveying efficiency. While avoiding the scattering of magnetic waste, it can meet the production to the greatest extent and complete the operation.
