Description

Technical Field

[0001] The present invention relates to the technical field of weighing equipment, and in particular to an unattended weighing Internet of Things equipment. Background Art

[0002] Weighing equipment is an instrument used to measure the weight of large objects in industry or trade. It is widely used in industry, agriculture, commerce, scientific research, medical and health departments. It is an essential equipment for manufacturing, assembly, quality inspection, transportation, sales, medical diagnosis and other links. For example, in the automotive manufacturing industry, electronic scales are used to accurately measure the weight of raw materials, parts and finished products to ensure product quality. In supermarkets, electronic scales and pricing scales are used for commodity sales and measurement to protect customers' purchasing rights.

[0003] After long-term use, the surface of current weighing equipment will inevitably accumulate dust, oil stains and various pollutants. These impurities not only directly cover the key parts of the sensor, but also gradually penetrate below the surface of the sensor, causing a significant impact on the working state of the sensor. The pollutants covering the surface of the sensor will interfere with the sensor's accurate perception of weight. Due to the presence of these impurities, the sensor may produce deviations when receiving and converting weight signals, resulting in the final weighing result being inconsistent with the actual weight. Some tiny particles may also penetrate into the interior of the sensor through tiny gaps on the sensor, causing potential damage to the sensor's mechanical structure and electronic components.

A mounting shell 322 is fixedly installed between the outer walls of the remaining two of the four sliders 304. Three groups of shaft holes 323 are opened on the outer wall of the mounting shell 322.

The outer walls of the three rotating shafts 324 are all fixedly sleeved with sprockets 336, and the outer walls of the three sprockets 336 are movably sleeved with chains 337.

[0022] In this embodiment, when the visual detector 106 finds that there are many pollutants accumulated on the surface of the conveying platform 103 below, the motor 1 312 will be started. At this time, the motor 1 312 will drive the rotating shaft 2 310 to rotate inside the shaft hole 1 305, and drive the two gears 2 311 on the outer wall of the rotating shaft 2 310 to rotate accordingly. Since each gear 2 311 is meshed and connected with two gears 1 309, the four gears 1 309 rotate accordingly, and the gear 1 309 will drive the racks 307 on both sides to rise and fall respectively. When the left rack 307 rises, it will drive the slider 1 304 to slide on the outer wall of the guide rail 303, and drive the cleaning brush 325 to rise with the help of the mounting shell 322, and contact with the belt of the conveying platform 103, and then the motor 3 326 starts to start, The output end of the rotating shaft 4 324 is driven to rotate inside the shaft hole 4 323. At this time, the sprocket 336 located on the outer wall of the rotating shaft 4 324 starts to rotate synchronously. The sprocket 336 will drive the chain 337 on the outer wall to start moving, and with the help of the chain 337, the remaining two sprockets 336 and the rotating shaft 4 324 are driven to rotate. The three rotating rotating shafts 4 324 will drive the cleaning brush 325 on the outer wall to rotate, thereby sweeping away the pollutants on the top of the conveying platform 103. At this time, the vacuum pump 334 is started together, and the air inside the installation shell 322 is extracted through the vacuum pipe 333 and discharged through the air supply pipe 335. At this time, negative pressure will be formed inside the installation shell 322, and the swept dust will be quickly sucked into the collection box 331 inside the installation shell 322, so that the dust can be concentrated and processed to prevent it from spreading everywhere. Diffusion can not only prevent dust from adhering to the belt surface again and affecting the cleaning effect, but also avoid dust pollution to the environment. When there are many pollutants in the collection box 331 that need to be poured out, people can turn the rotating block 328 to make it rotate ninety degrees on the surface of the fixed rod 327, thereby releasing the limitation of the collection box 331, and then pull the handle 332 to make the slider 2 330 be pulled out from the inside of the slide groove 329. At this time, the collection box 331 is synchronously taken out from the inside of the mounting shell 322, which is convenient for the user to pour out the internal pollutants. When the cleaning is completed, when the visual detector 106 finds that there are still residual pollutants on the surface of the belt below, the motor 1 312 starts to reverse and drives the four gears 1 309 to rotate in the opposite direction. At this time, the two sliders 1 304 on the left side drop accordingly. , the cleaning brush 325 is separated from the belt, and the two sliders 304 on the right side begin to rise. At this time, the liquid storage tank 313 drives the sponge brush 317 to contact the belt, and the motor 2 315 is started, driving the rotating shaft 316 to rotate inside the shaft hole 314, and the sponge brush 317 on the outer wall of the rotating shaft 316 also starts to rotate. Since there is cleaning liquid inside the liquid storage tank 313, the lower end of the sponge brush 317 is always immersed in the cleaning liquid. Therefore, when the sponge brush 317 rotates, its surface will evenly absorb the cleaning liquid. The two cooperate with each other to effectively wipe off the residual contaminants on the surface of the belt. The scraper 319 at the bottom of the liquid storage tank 313 can scrape off the contaminants on the surface of the sponge brush 317 in time. When the internal cleaning liquid has been used for a long time, the user can rotate and unscrew the sealing cover 321,The cleaning liquid is discharged from the liquid outlet 320, and then the clean cleaning liquid can be injected into the interior again through the one-way valve 318. The device can ensure the cleanliness of the belt to the greatest extent through both dry and wet cleaning methods, thereby extending the service life of the device and avoiding the impact on the weighing results.

[0023] Embodiment 2: According to Figure 1-Figure 4 As shown, the detection mechanism 1 includes a weighing device 101, a group of brackets 102 are fixedly installed on the top of the weighing device 101, a conveying platform 103 is fixedly installed between the tops of the group of brackets 102, a display 104 is fixedly installed on one side of the outer wall of the conveying platform 103, a conveyor 105 is fixedly installed on one side of the outer wall of the conveying platform 103, and a visual detector 106 is fixedly installed on one side of the outer wall of the conveyor 105; The unloading mechanism 2 includes a conveyor 201 , a conveyor 3 202 is fixedly installed on one side of the outer wall of the conveyor 201 , and a conveyor 4 203 is fixedly installed on one side of the outer wall of the conveyor 201 .

[0024] In this embodiment, after the user places the object to be weighed on the top of conveyor 105, conveyor 105 will transport the object forward. When the object reaches the surface of conveyor platform 103, conveyor platform 103 will be pressed downward. Since conveyor platform 103 is located on the top of weighing device 101, weighing device 101 can measure the weight of the object with the help of internal sensor. After the measurement, conveyor platform 103 will continue to transport the object forward and send the object away through conveyor 201. The device cooperates with multiple transmission machines to continuously perform weighing and unloading operations, which not only reduces the waiting time of manual operation and improves the overall production efficiency, but also reduces manual participation and reduces dependence on human resources.

[0025] Embodiment 3: According to Figure 1-Figure 5 As shown, the unloading mechanism 2 includes a conveyor 201, a conveyor 3 202 is fixedly installed on one side of the outer wall of the conveyor 201, a conveyor 4 203 is fixedly installed on one side of the outer wall of the conveyor 201, two mounting seats 204 are fixedly installed on one side of the outer wall of the conveyor 201, and a group of movable holes 205 are opened on the outer walls of the two mounting seats 204. A group of cylinders 206 are fixedly installed on one side of the outer walls of the two mounting seats 204, and piston rods 207 are provided at the output ends of the two groups of cylinders 206, and the inner walls of the two groups of movable holes 205 are movably inserted into the outer walls of the piston rods 207, and push plates 208 are fixedly installed between the outer walls of the two groups of piston rods 207, one side of the outer wall of the conveying platform 103 is fixedly connected to one side of the outer wall of the conveyor 201, and the outer wall of the weighing device 101 is fixedly connected to the outer walls of the two support frames 301.

[0026] In this embodiment, when the object arrives at the tail end of conveyor 201, conveyor 201 can bring the object to the front of conveyor 3 202 or conveyor 4 203 according to the weight of the object, and then a group of cylinders 206 at the corresponding position starts to start, so that the piston rod 207 extends from the inside of the movable hole 205. At this time, a group of piston rods 207 starts to drive the push plate 208 forward, pushing the object onto the corresponding conveyor, so that the device can classify the materials according to weight, which is convenient for subsequent inventory management, packaging and transportation, and also reduces the need for manual operation, reduces labor costs, and avoids human errors.

[0027] The working principle of the whole mechanism is as follows: when the user needs to weigh an object, he or she only needs to place the object on the top of the conveyor 105. Then, the conveyor 105 will start and smoothly convey the object forward. When the object reaches the surface of the conveyor platform 103, it will exert pressure to make the conveyor platform 103 drop. Since the conveyor platform 103 is directly installed on the top of the weighing device 101, the precision sensor inside the weighing device 101 can immediately capture this tiny displacement change and accurately measure the weight of the object accordingly. Once the weight measurement is completed, the conveyor platform 103 will quickly convey the object forward. At this time, the conveyor 201 will take over, take over the object from the conveyor platform 103, and continue to convey it forward. During the whole process, multiple conveyors are closely connected. The device cooperates to ensure the continuity and efficiency of weighing and unloading operations. When the object reaches the end of conveyor 201, the device will automatically guide it to conveyor 3 202 or conveyor 4 203 according to the weight of the object. This decision-making process is realized through the built-in control system, which can intelligently classify objects according to the preset weight range. Subsequently, a group of cylinders 206 at the corresponding positions will start to push the piston rods 207 out of the movable holes 205. These piston rods 207 will drive the push plates 208 forward and accurately push the objects to the corresponding conveyors. In this way, the device can realize the function of classifying materials according to weight, which provides great convenience for subsequent inventory management, packaging and transportation. When the visual detector 10 When it is detected that a lot of pollutants have accumulated on the surface of the conveying platform 103, the motor 1 312 will be immediately triggered to start. The motor 1 312 drives the rotating shaft 2 310 to rotate in the shaft hole 1 305, thereby driving the two gears 2 311 to rotate synchronously. Since each gear 2 311 is meshed with two gears 1 309, the four gears 1 309 will also rotate accordingly. The rotation of these gears 1 309 will drive the racks 307 on both sides to rise and fall respectively. When the rack 307 on the left rises, it will drive the slider 1 304 to slide along the guide rail 303, and then the cleaning brush 325 will rise through the mounting shell 322 and contact the belt of the conveying platform 103. At this time, the motor 326 starts to work and drives the rotating shaft 4 324 to rotate in the shaft hole 4 323. The sprocket 336 on the outer wall of the rotating shaft 324 rotates accordingly, and drives the other two sprockets 336 and the rotating shaft 324 to rotate through the chain 337. The three rotating rotating shafts 324 drive the cleaning brush 325 to rotate, thereby effectively removing the pollutants on the top of the conveying platform 103. At the same time, the vacuum pump 334 extracts the air inside the installation shell 322 through the exhaust pipe 333 and discharges it through the air supply pipe 335. In this way, a negative pressure will be formed inside the installation shell 322, and the swept dust will be quickly sucked into the collection box 331, so as to realize the centralized treatment of dust. When the pollutants inside the collection box 331 accumulate to a certain extent and need to be poured out, people can rotate the rotating block 328 to rotate it ninety degrees to release the limitation on the collection box 331, and then pull the handle 332.The collecting box 331 is taken out from the inside of the mounting shell 322, so that the user can easily pour out the internal pollutants. If the visual detector 106 finds that there are still residual pollutants on the surface of the belt after cleaning, the motor 1 312 will start to reverse and drive the four gears 1 309 to rotate in the opposite direction. At this time, the two sliders 1 304 on the left will drop accordingly, so that the cleaning brush 325 is separated from the belt. At the same time, the two sliders 1 304 on the right start to rise, driving the liquid storage tank 313 and the sponge brush 317 to contact with the belt. After the motor 2 315 is started, it will drive the rotating shaft 316 to rotate in the shaft hole 314, thereby driving the sponge brush 317 to rotate. Since the liquid storage tank 313 is filled with cleaning liquid, the lower end of the sponge brush 317 is always immersed in the cleaning liquid. When the sponge brush 317 rotates, its surface will evenly absorb the cleaning liquid. In this way, the cooperation between the sponge brush 317 and the cleaning liquid can effectively wipe off the pollutants remaining on the belt surface. At the same time, the scraper 319 at the bottom of the liquid storage tank 313 can timely scrape off the pollutants on the surface of the sponge brush 317. When the cleaning liquid inside the liquid storage tank 313 is used for a long time, the user can rotate and unscrew the sealing cover 321 to discharge the cleaning liquid from the liquid outlet 320. Then, the clean cleaning liquid can be injected into the liquid storage tank 313 again through the one-way valve 318. The device combines the dry and wet cleaning methods to ensure the cleanliness of the belt to the greatest extent, thereby extending the service life of the device and avoiding the weighing result being affected by pollutants.
