Description

Technical Field

[0001] The invention relates to the technical field of powder conveying devices, and in particular to a conveying device for producing sintering flux. Background Art

[0002] Sintered flux is an auxiliary material used in the welding process, which is mainly used to protect the molten pool, remove oxides, and improve the mechanical properties of the weld. The sintered flux is prepared from a variety of powder raw materials through mixing, molding and sintering processes. The existing powder raw materials are often transported by screw conveyors. However, when using screw feeders to transport sintered flux powder raw materials, material blockage is a common problem. Due to the high viscosity of the transported materials (organic matter, adhesives, etc.), the spiral blades in the screw conveyor drive the materials for a long time, which easily causes the materials to aggregate and agglomerate. The subsequent part of the agglomerated materials sticks to the inner wall of the barrel, affecting the rotation of the screw and causing the barrel in the screw conveyor to be blocked. At the same time, due to the presence of particles of different particle sizes in the powder raw materials, the larger particles in the raw materials may be stuck in the gap between the spiral blades and the barrel, hindering the flow of other materials, resulting in partial or overall blockage, and material blockage affects the production efficiency of the sintered flux.

DETAILED DESCRIPTION

[0055] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly introduced below. Obviously, the drawings in the following description only relate to some embodiments of the present invention, but are not intended to limit the present invention.

[0056] Embodiment 1: A conveying device for producing sintered flux, such as Figure 1-Figure 5As shown, it includes: a storage bin 1; a material guide pipe 11, which is fixedly connected and communicated with the storage bin 1 and is fixedly connected to a motor 12 through a support; a rotating rod 13, which is rotatably arranged in the material guide pipe 11 and is fixedly connected to a first auger 131; a first rotating sleeve 14, which is rotatably arranged in the material guide pipe 11 and is rotatably connected to the rotating rod 13 and is fixedly connected to a second auger 141; a rotating shaft 15, which is arranged on the rotating rod 13 and is rotatably arranged with a second rotating sleeve 16, and the second rotating sleeve 16 is connected to the output shaft of the motor 12; a fixed plate 17, which is fixedly connected to the rotating shaft 15 and is connected to the second rotating sleeve 16 A torsion spring is installed between the two ends of the second rotating sleeve 16; a limiting rod 18 has a plurality of circumferentially distributed limiting grooves, and the limiting rods 18 are all fixedly connected to the second rotating sleeve 16; the fixed disk 17 is provided with a plurality of circumferentially distributed limiting grooves, and the limiting rods 18 are located in adjacent limiting grooves on the fixed disk 17; a trigger mechanism is arranged on the first rotating sleeve 14, and the second auger 141 and the first auger 131 are separately arranged and combined with the trigger mechanism, so that when the agglomerated raw materials in the material guide tube 11 affect the rotation state of the first auger 131 and the second auger 141, the first auger 131 is rotated alone to drive out and crush the agglomerated materials.

[0057] In the above scheme, there are two limit rods 18 (this number is shown in the accompanying drawings, and the actual number can be set according to the specific situation, and the two are circumferentially equidistantly distributed, which is used to improve the stability of the device during operation. The number of the remaining components described below is also only the number shown in the accompanying drawings, and the circumferentially distributed components described below are all circumferentially equidistantly distributed). The second auger 141 is in contact with the first auger 131, and the two cooperate to form a complete auger. In the initial state, the torsion spring connected to the second rotating sleeve 16 is in a torsion state, and at this time the second rotating sleeve 16 is fixedly connected to the output shaft of the motor 12. In subsequent embodiments, the two can be in other connection relationships. In the present invention, the rotation speed of the motor 12 can be adjusted according to the proportion of the raw materials it transports in the formula, so as to facilitate the mixing of multiple raw materials in equal proportions, thereby accelerating the preparation efficiency of the sintered flux. At the same time, the rotation speed of the device during operation will not be too fast, so the parts in the device will not be affected by centrifugation and affect its normal operation.

[0058] like Figure 4 , Figure 6 and Figure 7As shown, the trigger mechanism includes: a first sliding frame 2, which is slidingly arranged on the first rotating sleeve 14 in a limited manner, and a tension spring is installed between the first sliding frame 2 and the first rotating sleeve 14, and the fixed plate 17 is provided with a blind hole, and the first sliding frame 2 is limitedly matched with the blind hole of the fixed plate 17; a connecting rod 21, which has a plurality of circumferentially distributed, and the plurality of connecting rods 21 are fixedly connected to the first sliding frame 2; a fixed sleeve 22, which is fixedly connected to the plurality of connecting rods 21, and the fixed sleeve 22 is provided with a plurality of circumferentially distributed guide grooves 221, and the guide grooves 221 are composed of arc grooves 222 and inclined grooves 223, and the open end of the inclined groove 223 is close to the second rotating sleeve 16; a first fixed frame 23, which has a plurality of circumferentially distributed, and the plurality of first fixed frames 23 are fixedly connected to the second rotating sleeve 16, and the first fixed frames 23 are located in adjacent guide grooves 221 and slide; a limiting assembly, which is arranged on the fixed sleeve 22, and the limiting assembly is used to limit the rotation of all the first fixed frames 23.

[0059] In the above scheme, the first sliding frame 2 has four cylindrical rods, one of which is longer than the other three, and a ball is provided at the end of the long cylindrical rod on the first sliding frame 2. In the initial state, the tension spring between the first sliding frame 2 and the first rotating sleeve 14 is in a stretched state. There are four connecting rods 21 and two first fixed frames 23. The connecting rods 21 and the first fixed frames 23 are equidistantly distributed circumferentially to improve the stability of the two during work. The circumferential curvature of the guide groove 221 is the same as the curvature of the upper limit groove of the fixed disk 17. The arc groove 222 is used for the first fixed frame 23 to rotate circumferentially and twist the torsion spring connected to the second rotating sleeve 16, that is, to buffer the raw material resistance suffered by the first auger 131 and the second auger 141.

[0060] like Figure 6-Figure 8 As shown, the limiting assembly includes: a first sliding sleeve 3, which is slidingly arranged in the fixed sleeve 22 in a limiting manner, and a tension spring is installed between the fixed sleeve 22; a limiting block 31, which has a plurality of groups distributed circumferentially, and the plurality of groups of limiting blocks 31 are all fixedly connected to the first sliding sleeve 3, and each group of limiting blocks 31 corresponds to adjacent arc grooves 222, respectively, and the limiting blocks 31 are used to limit the sliding of adjacent first fixed frames 23 in adjacent arc grooves 222.

[0061] In the above scheme, in the initial state, the tension spring between the first sliding sleeve 3 and the fixed sleeve 22 is in a stretched state, the limit block 31 is approximately triangular, and the number of each group of limit blocks 31 is two (the actual number can be adjusted accordingly according to the length of the arc groove 222 and the size of the limit block 31). The limit block 31 is used to hinder the movement of the adjacent first fixed frame 23, increase the trigger threshold when the second auger 141 disengages from rotating with the first auger 131, maintain the stability and uniformity of its raw material delivery amount, and further ensure that multiple raw materials are mixed in equal proportions.

[0062] Specific working principle: Different raw materials of sintering flux are stored in different storage bins 1. When sintering flux needs to be produced, the operator starts the motors 12 at different raw materials storage bins in sequence. Taking one of them as an example, the motor 12 drives the second rotating sleeve 16 to rotate clockwise (the rotation direction is in the attached Figure 2 The second rotating sleeve 16 drives the fixed plate 17, the rotating shaft 15 and the rotating rod 13 to rotate together through the connected torsion spring. Since the first sliding frame 2 is inserted into the blind hole of the fixed plate 17, the fixed plate 17 rotates through the first sliding frame 2 to drive the first rotating sleeve 14 to rotate together.

[0063] The rotating rod 13 and the first rotating sleeve 14 rotate together, so that the combined first auger 131 and the second auger 141 rotate together to drive the raw materials falling into the storage bin 1 to move rightward, and the raw materials fall into the mixing tank through the right end outlet of the storage bin 1, completing the transportation of the raw materials.

[0064] During the raw material conveying process, under the tension of the tension spring connected to the first sliding sleeve 3, the limit block 31 limits the adjacent first fixed frame 23, so that the second rotating sleeve 16 remains stationary relative to the fixed sleeve 22. Since the first sliding frame 2 is inserted into the blind hole of the fixed disk 17, the fixed disk 17 remains relatively stationary with the fixed sleeve 22 through the first sliding frame 2 and the connecting rod 21, that is, the second rotating sleeve 16 remains fixed relative to the fixed disk 17, the rotating shaft 15, the rotating rod 13 and the first rotating sleeve 14. At this time, the second rotating sleeve 16 rotates through the connected parts to drive the first auger 131 and the second auger 141 to rotate smoothly, so as to maintain the uniform speed and uniformity of the raw material conveying of the device, thereby facilitating the subsequent uniform mixing of multiple raw materials in equal proportions and improving the preparation efficiency.

[0065] After the device has transported raw materials for a long time, if the resistance encountered by the first auger 131 and the second auger 141 in rotating is greater than the torsion of the torsion spring between the second rotating sleeve 16 and the fixed disk 17, the second rotating sleeve 16 rotates to twist the connected torsion spring. At this time, the second rotating sleeve 16 rotates relative to the fixed disk 17 and the fixed sleeve 22, so that the second rotating sleeve 16 drives the first fixed frame 23 to rotate in the adjacent arc groove 222. The first fixed frame 23 rotates and gradually passes through the adjacent limit blocks 31. After the adjacent first fixed frames 23 are limited by multiple limit blocks 31, the raw materials in the guide tube 11 are prevented from being affected by factors such as local agglomeration and the like. The rotation of the first auger 131 and the second auger 141 is further improved. As the resistance encountered by the first auger 131 and the second auger 141 in rotating gradually increases, the second rotating sleeve 16 drives the first fixed frame 23 to rotate relative to the fixed sleeve 22, so that the first fixed frame 23 moves along the guide groove 221.

[0066] When the first fixed frame 23 rotates to the adjacent inclined groove 223, the resistance encountered by the first auger 131 and the second auger 141 in rotation continues to increase, causing the first fixed frame 23 to rotate and squeeze the adjacent inclined groove 223. The squeezed fixed sleeve 22, the connecting rod 21 and the first sliding frame 2 move to the right together, and the movement of the first sliding frame 2 stretches the tension spring connected to it, and the first sliding frame 2 moves to the right and is gradually pulled out of the blind hole of the fixed plate 17. When the first sliding frame 2 moves to the right and is gradually pulled out of the blind hole of the fixed plate 17, the raw materials in the guide tube 11 seriously hinder the rotation of the first auger 131 and the second auger 141 due to factors such as agglomeration.

[0067] When the first fixed frame 23 rotates to fit the left side of the fixed sleeve 22, the first sliding frame 2 simultaneously releases the limiting cooperation with the blind hole on the fixed plate 17. At this time, the output shaft of the motor 12 drives the first auger 131 to continue to rotate clockwise through the second rotating sleeve 16 and the connected torsion spring, fixed plate 17, rotating shaft 15 and rotating rod 13. At this time, the second auger 141 is blocked by the raw materials in the guide tube 11 and remains stationary.

[0068] During the rotation of the first auger 131, the amount of raw materials driven by it becomes smaller, and the torque of the torsion spring connected to the second rotating sleeve 16 becomes larger, so that a small amount of raw materials is further pushed with greater force, and the raw materials in the material guide pipe 11 are helped to resume movement and transportation, so that the device can maintain continuous material transportation. The rotation of the first auger 131 is staggered with the second auger 141, and the raw materials in the material guide pipe 11 are further sheared and crushed, and the resistance force of the raw materials on the second auger 141 is gradually weakened.

[0069] After the amount of raw materials discharged from the material guide tube 11 is restored, the resistance of the raw materials to the second auger 141 becomes weaker. At this time, under the tension of the tension spring connected to the first sliding frame 2, the first sliding frame 2 moves to the right, and the ball bearings on it are in contact with the right side of the fixed plate 17. After the amount of raw materials discharged from the material guide tube 11 is restored, the torsion spring connected to the second rotating sleeve 16 is gradually released to restore the initial state. When the second rotating sleeve 16 drives the first fixed frame 23 to rotate to face the adjacent inclined groove 223, and the first sliding frame 2 is brought After one end with the ball is facing the blind hole of the fixed plate 17, the first sliding frame 2 is inserted into the blind hole of the fixed plate 17 under the tension of the tension spring connected to the first sliding frame 2, and the first fixed frame 23 rotates along the direction of the adjacent inclined groove 223. After the first fixed frame 23 rotates to the adjacent arc groove 222, since the torque required by the torsion spring connected to the second rotating sleeve 16 is greater than the limiting force generated by the limit block 31, the first fixed frame 23 will move in the opposite direction and reset, and then the above operations are completed to uniformly and evenly transport the raw materials.

[0070] After the quantitative raw material is delivered to the storage bin 1, the operator turns off all the motors 12 and then performs subsequent processing steps. If the next batch of sintering flux needs to be produced, the above operation can be repeated.

[0071] Embodiment 2: Based on embodiment 1, Fig. 9 and Fig.10 As shown, it also includes: a delay mechanism, which is arranged on the fixed disk 17, and the delay mechanism is used to limit the movement of the fixed sleeve 22. The delay mechanism includes: a sliding plate 4, which has a plurality of circumferentially distributed, and the plurality of sliding plates 4 are all slidably arranged in the fixed disk 17, and the sliding plate 4 is provided with an inclined groove, and the limiting rod 18 is located in the inclined groove of the adjacent sliding plate 4 and slides, and all the sliding plates 4 cooperate with the fixed disk 17 to form an annular limiting protrusion; a second sliding frame 41, which has a plurality of circumferentially distributed, and the plurality of second sliding frames 41 are respectively slidably arranged on the adjacent connecting rods 21, and a tension spring is installed between the second sliding frame 41 and the adjacent connecting rods 21, and the second sliding frame 41 is limitedly cooperated with the annular limiting protrusion composed of the plurality of sliding plates 4 and the fixed disk 17, and the second sliding frame 41 is provided with two inclined surfaces, and the length of the inclined surface of the second sliding frame 41 close to the first sliding frame 2 is greater than the length of the inclined surface on the other side thereof; a delay component, which is arranged in the fixed disk 17, and the delay component is used to delay the plurality of sliding plates 4 from approaching each other.

[0072] In the above scheme, in the initial state, the tension spring between the second sliding frame 41 and the adjacent connecting rod 21 is in a stretched state, the number of sliding plates 4 is two, and the inclined groove of the front sliding plate 4 is inclined backward from top to bottom. The left inclined surface on the second sliding frame 41 cooperates with the two sliding plates 4 and the fixed plate 17 to form an annular limiting protrusion, which is used to guide the connecting rod 21 to drive the fixed sleeve 22 to move to the right, so that the left side surface of the fixed sleeve 22 is away from the first fixed frame 23, thereby reducing the wear between the fixed sleeve 22 and the first fixed frame 23.

[0073] like Fig.10 and Fig.11 As shown, the delay assembly includes: a fixed shell 5, which has a plurality of circumferentially distributed, and the plurality of fixed shells 5 are fixedly connected to the fixed disk 17, and the fixed shell 5 is filled with liquid; a sliding push rod 51, which has a plurality of circumferentially distributed, and the plurality of sliding push rods 51 are respectively slidably arranged in adjacent fixed shells 5, and a plurality of through holes are arranged at one end of the sliding push rod 51 located in the adjacent fixed shell 5, and a one-way valve is installed in the through hole of the upper part of the sliding push rod 51.

[0074] In the above scheme, the fixed shell 5 and the sliding push rod 51 each have two, the fixed shell 5 is filled with liquid, the liquid does not fill the fixed shell 5, the fixed shell 5 is also filled with air, the air is used to adapt to the sliding of the adjacent sliding push rod 51, the sliding push rod 51 has six through holes, three of the through holes on the sliding push rod 51 are installed with one-way valves, the one-way valve of the sliding push rod 51 is used for the liquid to pass through the six through holes on the sliding push rod 51 during the process of its retraction into the fixed shell 5, and then when the sliding push rod 51 is reset, the liquid cannot pass through the one-way valve on it, reducing the flow cross-section of the liquid on the sliding push rod 51, thereby delaying the reset of the sliding push rod 51, and extending the limit of the second sliding frame 41 by the annular limiting protrusion composed of multiple sliding plates 4 and the fixed disk 17.

[0075] Specific working principle: During the above-mentioned raw material conveying process, when the raw material is blocked and affects the rotation of the first auger 131 and the second auger 141, the above-mentioned operation is repeated to make the second rotating sleeve 16 drive the limiting rod 18 and the first fixed frame 23 to rotate relative to the fixed disk 17, wherein the first fixed frame 23 rotates and moves along the adjacent arc groove 222 and the adjacent inclined groove 223, and the limiting rod 18 rotates relative to the fixed disk 17 to squeeze the inclined groove of the adjacent sliding plate 4, so that the sliding plate 4 extends outward, and the extension and movement of the sliding plate 4 drives the adjacent sliding push rod 51 to move together, and during the movement of the sliding push rod 51, the liquid in the adjacent fixed shell 5 passes through the six through holes and the one-way valve thereon, and finally the two sliding plates 4 and the fixed disk 17 form a complete annular limiting protrusion.

[0076] After the first fixed frame 23 rotates and squeezes the adjacent inclined groove 223, the first sliding frame 2 and all the connecting rods 21 drive all the second sliding frames 41 to move together, and the second sliding frame 41 moves so that its right inclined surface contacts the step formed by the sliding plate 4 and the fixed disk 17. Subsequently, the squeezed second sliding frame 41 moves and stretches the connected tension spring. When the inclined surface on the left side of the second sliding frame 41 moves to the annular limiting protrusion formed by the sliding plate 4 and the fixed disk 17, under the tension of the tension spring connected to the second sliding frame 41, the second sliding frame 41 moves in the opposite direction and resets. At the same time, under the squeezing and guiding action of the right inclined surface of the second sliding frame 41, the second sliding frame 41 drives the connecting rod 21 and the first sliding frame 2 to move further to the right, so that the first fixed frame 23 is separated from the fixed sleeve 22, avoiding continuous wear between the first fixed frame 23 and the fixed sleeve 22 during the subsequent rotation process, thereby indirectly extending the service life of the device.

[0077] After the annular limiting protrusion composed of the sliding plate 4 and the fixed disk 17 is limited and matched with the second sliding frame 41, the motor 12 works to drive the rotating rod 13 and the first auger 131 to rotate through the connected parts to repeat the above operation, and the raw materials in the guide tube 11 are rotated, driven and crushed. After the material movement rate in the guide tube 11 is gradually restored, the torsion springs connected to the second rotating sleeve 16 are released and reset. At this time, the second rotating sleeve 16 drives the limiting rod 18 to rotate and reset in the opposite direction relative to the fixed disk 17. At this time, the liquid in the fixed shell 5 cannot pass through the one-way valve in the through hole on the adjacent sliding push rod 51. At this time, the flow cross-section of the liquid in the fixed shell 5 becomes smaller, so that the sliding plate 4 is slowly reset, and the rotation time of the single first auger 131 is extended, and the raw materials in the auxiliary guide tube 11 are further crushed, which is convenient for the subsequent device to continue to transport the raw materials stably and at a uniform speed.

[0078] After the sliding plate 4 is completely reset, when the second sliding frame 41 rotates to the sliding plate 4 area again, under the tension of the tension spring connected to the first sliding frame 2, the first sliding frame 2, the connecting rod 21, the fixing sleeve 22 and the second sliding frame 41 first move to the left a distance, so that the second sliding frame 41 is disengaged from the fixed plate 17, and the above operation is repeated to reset.

[0079] Embodiment 3: Based on embodiment 2, Fig.12 As shown, it also includes: a sliding ring 6, which is installed on the guide tube 11 through an elastic telescopic rod and is sleeved on the first rotating sleeve 14, the first sliding frame 2 is squeezed and matched with the sliding ring 6, the rotating rod 13 is slidingly connected with the rotating shaft 15 in a limited position, a spring is installed between the rotating rod 13 and the rotating shaft 15, and the output shaft of the motor 12 is rotatably connected with the second rotating sleeve 16; a protection mechanism is arranged on the second rotating sleeve 16, and the protection mechanism is used to prevent the motor 12 from being overloaded and damaged.

[0080] In the above scheme, a rubber pad is provided on the left side of the sliding ring 6, and the rubber pad is used to increase the friction between the sliding ring 6 and the first sliding frame 2. Four elastic telescopic rods are installed on the right side of the sliding ring 6, and springs are provided in the elastic telescopic rods. The sliding ring 6 is in contact with the first sliding frame 2 to limit the rotation of the first sliding frame 2.

[0081] like Fig.12 and Fig.13 As shown, it also includes: a second fixing frame 7, which has a plurality of circumferentially distributed, and the plurality of second fixing frames 7 are all fixed to the rotating rod 13, the rotating rod 13 is sealingly slidably connected with the first rotating sleeve 14, the inner wall of the first rotating sleeve 14 is provided with a wave groove 71, the second fixing frame 7 and the wave groove 71 are slidably matched, the rotating rod 13 and the first rotating sleeve 14 are both provided with a through hole for installing a one-way valve, the one-way valve on the rotating rod 13 and the one-way valve on the first rotating sleeve 14 are opened alternately, so as to gradually inject the gas into the guide pipe 11.

[0082] In the above scheme, there are two second fixed frames 7, the second fixed frames 7 are L-shaped, the wave groove 71 is annular, and the wave groove 71 has two peaks and two troughs. In the process of only the first auger 131 rotating to drive the material, the wave groove 71 guides the second fixed frame 7, so that the rotating rod 13 moves back and forth left and right. The rotating rod 13 moves left, so that the gas between it and the first rotating sleeve 14 enters the guide pipe 11 through the one-way valve on the first rotating sleeve 14. The gas flow helps to disperse the raw materials, thereby facilitating the movement of the raw materials in the guide pipe 11, maintaining the stability and uniformity of the raw material transportation of the device, and then the rotating rod 13 moves right, so that the external gas enters between the first rotating sleeve 14 and the rotating rod 13 through the one-way valve on the first rotating sleeve 14, and then the above operation is repeated.

[0083] like Figure 3 and Figure 6 As shown, the protection mechanism includes: a plurality of pins 8 distributed circumferentially, the second rotating sleeve 16 is provided with a plurality of through holes distributed circumferentially, the output shaft of the motor 12 is provided with a plurality of limiting holes distributed circumferentially, and the plurality of pins 8 are respectively inserted into adjacent through holes on the second rotating sleeve 16 and adjacent limiting holes on the output shaft of the motor 12; a second sliding sleeve 81 is slidably arranged on the second rotating sleeve 16, and there is damping between the second sliding sleeve 16, so as to cover the through holes on the second rotating sleeve 16 and limit all the pins 8.

[0084] In the above scheme, there are four pins 8, the strength of which is smaller than the shear force generated by the motor 12 at the maximum output power, and is used to protect the motor 12 from being overloaded and burned due to the blocking of the guide pipe 11 by the raw materials.

[0085] Specific working principle: when the device performs a single first auger 131 operation to transport raw materials, the first sliding frame 2 moves to squeeze the sliding ring 6. Due to the elastic effect of the elastic telescopic rod connected to the sliding ring 6, the sliding ring 6 is tightly attached to and squeezes the first sliding frame 2. Due to the limiting effect of the rubber pad on the left side of the sliding ring 6, the rotation of the first sliding frame 2 is further limited. During the subsequent rotation of the rotating shaft 15 driving the rotating rod 13, the two second fixed frames 7 on the rotating rod 13 move along the wave groove 71, so that the rotating rod 13 reciprocates in the first rotating sleeve 14. The reciprocating movement of the rotating rod 13 drives the first auger 131 to reciprocate left and right together, thereby accelerating the discharge of the blocked raw material in this section of the guide pipe 11, and then cooperating with the rotating rod 13 to drive the first auger 131 to rotate, ensuring the continuous transportation of the raw materials in the guide pipe 11, that is, maintaining the production efficiency of the sintering flux.

[0086] After the material conveying of the material guide tube 11 is resumed, the elastic force of the spring connected between the rotating rod 13 and the rotating shaft 15 acts, and the second fixing frame 7 on the rotating rod 13 is located at the rightmost side of the wave groove 71, and the above operation is repeated to reset.

[0087] If the transported raw materials seriously block the material guide pipe 11, the single rotating rod 13 is unable to drive the material in the material guide pipe 11 to move. At this time, the motor 12 continues to rotate to shear all the pins 8. After the full load of the motor 12 acts on all the pins 8, the pins 8 are cut off, and then the output shaft of the motor 12 rotates relative to the second rotating sleeve 16 to prevent the motor 12 from burning out.

[0088] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
