Description
Technical Field
[0001] This invention relates to the field of glass product manufacturing technology, specifically to an automatic mixing and weighing device and system for multiple raw materials. Background Technology
[0002] The multi-material automatic mixing and weighing device is an integrated equipment whose main function is to accurately measure, uniformly mix, and automatically manage multiple materials to improve production efficiency and product quality. It is widely used in plastics processing, chemical, food, and pharmaceutical fields.
[0003] While traditional multi-raw material automatic mixing and weighing devices can improve production efficiency and product quality, after the materials used in glass manufacturing enter the weighing device for weighing, the valve is usually opened and the materials slide into the conveying pipe due to their own weight. In humid areas, where the moisture content in the air is high, a lot of material will stick to the inner wall of the weighing box, causing significant material loss. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides an automatic mixing and weighing device for multiple raw materials that can prevent excessive material from adhering to the inner wall of the weighing box in humid environments.
[0005] To address the problems in the prior art, the present invention provides an automatic mixing and weighing device and system for multiple raw materials, including a weighing box and a central control system. The scraping assembly is installed on the weighing box, the motor is fixedly installed on the side wall of the support frame, one end of the threaded rod is fixedly connected to the output shaft of the motor, the threaded rod is threadedly connected to the inside of the sliding plate, the sliding plate is slidably connected to the inside of the slide groove, the connecting plate is fixedly connected to one side of the sliding plate, one end of the connecting column is fixedly connected to the other side of the connecting plate, the other end of the connecting column is fixedly connected to one side of the mounting box, the mounting box is slidably connected to the inside of the weighing box, two sets of scrapers are slidably connected to the inside of the mounting box, and two sets of springs are installed between the two sets of scrapers.
[0006] Specifically, the scraping assembly includes a support frame, a motor, a threaded rod, a sliding plate, a sliding groove, a connecting plate, a connecting column, a mounting box, a spring, and a scraper. The support frame is fixedly installed on one side of the weighing box, and the two sets of sliding grooves are fixedly installed on both sides of the weighing box.
[0007] Specifically, the weighing box is equipped with a lifting assembly. The lifting assembly includes a linear guide rail, a connecting rod, a sliding column, and a fixing block. The fixing block is fixedly installed at the lower end of the weighing box. One side of the fixing block is fixedly connected to one side of the connecting rod. One end of the connecting rod is slidably connected to the inside of the linear guide rail. The linear guide rail is fixedly installed on a support frame. The inside of the connecting rod is slidably connected to the sliding column. The sliding column is fixedly installed on the support frame and located on one side of the linear guide rail.
[0008] Specifically, a set of mixing drums is installed on the upper end of the weighing box, and a support rod is fixedly connected to the outer wall of the mixing drum. The support rod is fixedly connected to the side wall of the support frame. A set of discharge ports is fixedly installed at the lower end of the mixing drum, and the discharge ports are slidably connected to the interior of the weighing box.
[0009] Specifically, the central control system is connected to the weighing module, the mixing module, and the conveying module. The central control system uses an industrial computer as a carrier. The weighing module is used to weigh the materials and contains multiple weighing devices and a signal receiving and transmitting module. The mixing module can mix the materials required for glass manufacturing together. The conveying module is used for material transmission and contains multiple conveyor belts, with each conveyor belt corresponding to a weighing device.
[0010] Specifically, the weighing module and the loss calculation module are connected and both are located inside the industrial computer. The weighing module transmits the data obtained from each weighing device to the loss calculation module, which calculates the loss during the conveying process based on the conveying sequence.
[0011] Specifically, the loss calculation module, loss comparison module, and warning module are interconnected and all located inside the industrial computer. The loss calculation module transmits the calculated loss to the loss comparison module, which compares this loss data with standard loss data. If the error exceeds the pre-defined threshold range, the loss comparison module transmits a signal to the central control system, which then transmits a signal to the warning module. The warning module includes a warning light and a signal receiving module. Upon receiving the signal, the warning light inside the warning module illuminates, and the warning signal is displayed on the industrial computer's screen to alert the staff.
[0012] The beneficial effects of this invention are:
[0013] 1. In this invention, after the motor starts, it can drive the slide plate to slide inside the slide groove. During the sliding process, the slide plate will drive the connecting plate, connecting column, mounting box and scraper to slide. The scraper will scrape the inner wall of the weighing box, thereby avoiding excessive material sticking to the inner wall of the weighing box and causing unnecessary loss.
[0014] 2. In the process of mounting the box and the scraper sliding, the material can be quickly pushed out of the weighing box and into the conveying pipe for transport, thereby speeding up the work efficiency.
[0015] 3. In this invention, the linear guide rail can drive the connecting rod to slide. After the material is mixed, the linear guide rail can drive the upper end of the weighing box to fit against the discharge port of the mixing barrel, thereby preventing the dust generated when the material slides down from spreading into the air.
[0016] 4. In this invention, a weighing device is installed in the mixing module and each group of conveying modules. The weighing device sends the weighed weight to the loss calculation module for calculation, and then enters the loss comparison module to compare it with the standard loss data. Once the loss difference exceeds the pre-set threshold range, the warning module will be activated to alert the staff, so that the staff can discover the problem of the equipment in time and make corrections.

[0031] Example 1:
[0032] like Figure 1 , Figure 3 as well as Figure 7 The illustrated automatic mixing and weighing device and system for multiple raw materials includes a weighing box 1 and a central control system. The scraping assembly 2 is installed on the weighing box 1. The motor 211 is fixedly installed on the side wall of the support frame 210. One end of the threaded rod 212 is fixedly connected to the output shaft of the motor 211. The threaded rod 212 is threadedly connected to the inside of the slide plate 213. The slide plate 213 is slidably connected to the inside of the slide groove 214. The connecting plate 215 is fixedly connected to one side of the slide plate 213. One end of the connecting column 216 is fixedly connected to the other side of the connecting plate 215. The other end of the connecting column 216 is fixedly connected to one side of the mounting box 217. The mounting box 217 is slidably connected to the inside of the weighing box 1. Two sets of scrapers 219 are slidably connected to the inside of the mounting box 217. Two sets of springs 218 are installed between the two sets of scrapers 219.
[0033] The scraping assembly 2 includes a support frame 210, a motor 211, a threaded rod 212, a sliding plate 213, a sliding groove 214, a connecting plate 215, a connecting column 216, a mounting box 217, a spring 218, and a scraper 219. The support frame 210 is fixedly installed on one side of the weighing box 1, and the two sets of sliding grooves 214 are fixedly installed on both sides of the weighing box 1.
[0034] like Figure 1 as well as Figure 2 As shown, a lifting assembly 3 is installed on the weighing box 1. The lifting assembly 3 includes a linear guide rail 310, a connecting rod 311, a sliding column 312, and a fixing block 313. The fixing block 313 is fixedly installed at the lower end of the weighing box 1. One side of the fixing block 313 is fixedly connected to one side of the connecting rod 311. One end of the connecting rod 311 is slidably connected to the inside of the linear guide rail 310. The linear guide rail 310 is fixedly installed on the support frame 113. The sliding column 312 is slidably connected inside the connecting rod 311. The sliding column 312 is fixedly installed on the support frame 113 and is located on one side of the linear guide rail 310.
[0035] A set of mixing barrels 110 is installed on the upper end of the weighing box 1. A support rod 112 is fixedly connected to the outer wall of the mixing barrel 110. The support rod 112 is fixedly connected to the side wall of the support frame 113. A set of discharge ports 111 is fixedly installed at the lower end of the mixing barrel 110. The discharge ports 111 are slidably connected to the interior of the weighing box 1.
[0036] like Figure 1 , Figure 3 as well as Figure 7 As shown, after the materials for manufacturing glass are mixed, the weighing box 1 is moved. When the discharge port 111 slides into the inside of the weighing box 1, the movement of the weighing box 1 is stopped, and the valve inside the discharge port 111 is opened. At this time, the materials inside the mixing tank 110 will enter the weighing box 1 for weighing. A weighing machine is installed on the bottom plate inside the weighing box 1 for weighing.
[0037] After the material is discharged into the weighing box 1, the weighing box 1 is slid downwards. When the lower end of the connecting plate 215 abuts against the upper end of the conveying pipe 114, the sliding stops and the motor 211 is started. At this time, the motor 211 will drive the threaded rod 212 to rotate in the forward direction. During the rotation of the threaded rod 212, it will push the slide plate 213 to slide forward. During the sliding of the slide plate 213, it will drive the connecting plate 215 to move together. The connecting plate 215 will drive the connecting column 216 to move. The connecting column 216 will drive the mounting box 217 to slide inside the weighing box 1. During the sliding of the mounting box 217, it will drive the scraper 219 to push the material inside the weighing box 1 out through the discharge port at one end of the weighing box 1, so that it falls into the inside of the conveying pipe 114. During the sliding process, the scraper 219 will scrape off the material adhering to its side wall and push it into the inside of the conveying pipe 114, so as to avoid too much material adhering to the inner wall of the weighing box 1 and causing unnecessary loss.
[0038] The installation of the triangular block allows the material to be discharged through the outlet of the weighing box 1 along its side wall. The scraper 219, driven by the mounting box 217, will be continuously squeezed by the side wall of the triangular block. Under the pressure of the triangular block, the scraper 219 will enter the interior of the mounting box 217. The two sets of scrapers 219 will continuously squeeze the spring 218. The elastic force generated by the spring 218 will drive the two sets of scrapers 219 to adhere to the side wall of the triangular block. The end of the scraper 219 that adheres to the side wall of the triangular block is wrapped with a cloth. The scraper 219 will drive the cloth to wipe off the material adhering to the side wall of the triangular block.
[0039] like Figure 1 as well as Figure 2 As shown, after the linear guide 310 is activated, it can drive the connecting rod 311 and the fixed block 313 to slide up and down, so that the discharge port 111 can enter the weighing box 1 to discharge material. This can effectively prevent the dust generated when the material enters the weighing box 1 from spreading into the air, causing environmental pollution and material loss.
[0040] Example 2:
[0041] like Figure 4 , Figure 5 as well as Figure 6 As shown, the central control system is connected to the weighing module, the mixing module, and the conveying module. The central control system uses an industrial computer as a carrier. The weighing module is used to weigh the materials and contains multiple sets of weighing devices and a signal receiving and transmitting module. The mixing module can mix the materials required for glass manufacturing together. The conveying module is used for material transmission and contains multiple sets of conveyor belts, with each set of conveyor belts corresponding to a set of weighing devices.
[0042] The weighing module and the loss calculation module are connected and both are located inside the industrial computer. The weighing module transmits the data obtained from each weighing device to the loss calculation module, which calculates the loss during the conveying process based on the conveying sequence.
[0043] The loss calculation module, loss comparison module, and warning module are interconnected and all are located inside the industrial computer. The loss calculation module transmits the calculated loss to the loss comparison module, which compares this loss data with standard loss data. If the error exceeds the pre-defined threshold range, the loss comparison module transmits a signal to the central control system, which then transmits a signal to the warning module. The warning module includes a warning light and a signal receiving module. Upon receiving the signal, the warning light inside the warning module illuminates, and the warning signal is displayed on the industrial computer screen to alert the operator.
[0044] like Figure 4 , Figure 5 as well as Figure 6 As shown, the weighing module in this invention contains multiple sets of weighing devices. The first weighing device corresponds to the mixing module, while each of the other weighing devices corresponds to a conveyor belt within a conveying module. After the materials are mixed, the valve at the discharge port opens, allowing the material to enter the first weighing device. The first weighing device weighs the material, and the resulting weight data is collected by the data collection module within the weighing module. After collection, the material inside the first weighing device is conveyed to the conveyor belt within the conveying module. The conveyor belt then transports the material to the second weighing device for weighing to check for losses during the conveying process. The data collected by the second weighing device is consistent with that of the first weighing device. Subsequently, the weighing module transmits the collected data to the loss calculation module via the data transmission module. The loss calculation module uses the following formula:
[0045] The total weight of materials before mixing - the weight measured by the first weighing device = the loss during mixing in the mixing module;
[0046] The weight measured by the first weighing device minus the weight measured by the second weighing device equals the loss during the conveyor belt conveying process (the weight measured by the previous set of weighing devices minus the weight measured by the next set of weighing devices).
[0047] After the loss calculation is completed, the loss data is first transmitted to the loss comparison module. The loss comparison module will then calculate the loss by comparing the received data with the standard data, first comparing the loss caused by the hybrid module using the formula:
[0048] Standard loss - Actual loss = Loss difference;
[0049] If the calculated loss difference exceeds the standard loss data range when compared with the standard data range, a signal will be transmitted to the central control system. The central control system will then transmit the signal to the warning module through the signal receiving and transmitting module. At this time, the warning light inside the warning module will light up to remind the staff that the loss is abnormal. The central control system will also display the specific location of the loss abnormality on the screen of the industrial computer. After observing this, the staff will start to check the mixing tank inside the mixing module to see if the increased loss is caused by external factors or by a malfunction of the mixing tank itself.
[0050] The loss comparison module calculates the loss caused by each conveyor belt separately, using the following formula:
[0051] Standard loss of conveyor belt - actual loss of conveyor belt = loss difference;
[0052] Consistent with the above comparison principle, if the data exceeds the standard range, a signal will be transmitted to the warning module. After observing this, the staff will begin to inspect the corresponding conveyor belt to identify the cause of the increased wear and tear. If it is a problem with the equipment itself, the staff can repair it in time to avoid further waste of resources. If it is affected by external factors, the staff can also take corresponding measures to reduce waste of resources.
[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
