Description

Technical Field

[0001] This utility model relates to a feeding device for the production of organosilicon coatings, and in particular to an organosilicon coating feeding device with a quantitative function. Background Technology

[0002] Organosilicon coatings are made primarily from silicone rubber latex and its nanocomposite emulsions, mixed with inorganic fillers and various additives. However, the production of organosilicon coatings requires precise proportions of raw materials. Therefore, in current production processes, the raw materials are manually weighed before being added to a mixing device. This manual weighing and feeding method is not only labor-intensive but also prone to spillage during handling and addition. Furthermore, the weighing process is susceptible to errors due to the weight of the containers, manual adjustments, and the long-term use of the weighing equipment, resulting in low feeding accuracy. Therefore, current organosilicon coating production processes suffer from both low feeding accuracy and high labor intensity. Utility Model Content

[0003] The purpose of this invention is to provide a device for feeding silicone coatings with a quantitative function. This invention not only improves the accuracy of feeding but also has the advantage of low labor intensity.

[0004] The technical solution of this utility model: a device for feeding organosilicon coatings with quantitative function, comprising a mounting frame with upper, middle, and lower layers and a storage tank disposed on the upper layer of the mounting frame, characterized in that: a metering channel is horizontally arranged in the middle layer of the mounting frame; an intermediate channel connects the top surface of the metering channel and the bottom surface of the storage tank, and a gear pump is installed on the intermediate channel; a pushing device is installed at one end of the metering channel, and a discharge pipe is installed on the bottom surface of the other end, with a pneumatic valve installed on the discharge pipe; a mounting groove is provided on the inner bottom surface of the metering channel between the pushing device and the discharge pipe, and a pressure sensor is installed in the mounting groove; a controller is installed on the mounting frame; the gear pump, pushing device, pneumatic valve, and pressure sensor are all electrically connected to the controller; when the storage tank... After the raw materials in the tank enter the metering channel through the intermediate channel and gear pump, the pressure sensor on the bottom surface of the metering channel automatically weighs the materials and sends the weighing results to the controller in real time. The controller then controls the start and stop of the gear pump and the pushing device based on the received weighing results, achieving accurate and precise feeding. Compared with manual weighing and feeding, this not only improves accuracy but also allows direct connection to the next station in the production of silicone coatings, eliminating the need for manual handling, reducing labor intensity, and improving overall work efficiency. Utilizing the characteristic that the operation of the gear pump is not highly correlated with the viscosity or density of the raw materials being transported, it is better and more suitable for conveying silicone coatings for extended periods, thus extending its service life.

[0005] In the aforementioned organosilicon coating feeding device with quantitative function, the pushing device includes a pushing cylinder mounted on a mounting frame, and a pushing rod mounted on the pushing cylinder. The end of the pushing rod is connected to a pushing plate located within a metering channel. A limit baffle is provided on the end of the pushing rod near the pushing cylinder, and the height of the limit baffle is greater than the height of the metering channel. A mounting groove is also provided on the end face of the metering channel near the pushing cylinder, and a piezoelectric sensor is installed in the mounting groove. The piezoelectric sensor is electrically connected to a controller. Through the limit baffle, whose height is greater than the height of the metering channel, and in conjunction with the piezoelectric sensor, the maximum position of the pushing cylinder driving the pushing rod and pushing plate to move is limited, and the start and stop of the pushing cylinder are controlled, achieving automated operation. This not only facilitates use but also prevents the pushing cylinder from driving the pushing plate to move excessively, ensuring operational stability.

[0006] In the aforementioned organosilicon coating feeding device with quantitative function, the side of the pusher plate away from the pusher cylinder is inclined, and a sealing ring is adhered to the outer surface of the pusher plate; an annular scraper is provided on the outer surface of the pusher plate, and the annular scraper is set on the side of the sealing ring away from the pusher cylinder; the inclined surface can guide the flow of the raw material remaining on the pusher plate, minimizing the raw material loss caused by the raw material remaining on the pusher plate, and the annular scraper can scrape off the raw material on the inner wall of the metering channel to the maximum extent, reducing production costs.

[0007] In the aforementioned organosilicon coating feeding device with quantitative function, the outer wall of the metering channel is covered with a heat insulation layer, and multiple evenly distributed electric heating plates are arranged between the heat insulation layer and the metering channel; all electric heating plates are electrically connected to the controller; the electric heating plates can be used to keep the raw materials inside the metering channel warm, so as to ensure the flowability of the raw materials and facilitate the subsequent feeding work; while the heat insulation layer can prevent the heat generated by the electric heating plates from being lost outward, maximizing the use of the heat energy of the electric heating plates to heat the internal environment of the metering channel, resulting in good energy saving effect.

[0008] In the aforementioned organosilicon coating feeding device with quantitative function, the inner wall and bottom surface of the mounting groove are also bonded with heat insulation layers.

[0009] In the aforementioned organosilicon coating feeding device with quantitative function, the discharge pipe has a rounded corner at the position corresponding to the connection with the metering channel; the storage tank has a transparent observation window on its side; the metering channel also has a transparent observation window at the position above the discharge pipe on its side; the observation windows allow operators to easily observe the raw material storage in the storage tank and the raw material output in the metering channel, so as to facilitate timely addition of raw materials or adjustment of the start time of the pusher cylinder, thus facilitating use.

[0010] Compared with existing technologies, this invention improves the existing silicone coating feeding device. By installing a pressure sensor on the inner bottom surface of the metering channel, along with a pushing device and a controller, the pressure sensor on the inner bottom surface of the metering channel automatically weighs the raw material after it enters the metering channel through the intermediate channel and gear pump. The weighing result is sent to the controller in real time, which then controls the start and stop of the gear pump and pushing device based on the received weighing result, achieving accurate feeding. Compared with manual weighing and feeding, this not only improves accuracy but also allows direct connection to the next station in silicone coating production, eliminating the need for manual handling, reducing labor intensity, and improving overall work efficiency. At the same time, by using the gear pump as the conveying device and switch of the intermediate channel, and taking advantage of the fact that the operation of the gear pump is not highly correlated with the viscosity or density of the conveyed raw material, it can be better and longer-lasting for conveying silicone coatings, extending its service life.

[0011] Furthermore, this invention also limits the maximum position of the pusher rod and pusher plate driven by the pusher cylinder, and controls the start and stop of the pusher cylinder by installing a limiting baffle plate with a height greater than that of the metering channel, in conjunction with a piezoelectric sensor on the side wall of the metering channel. This achieves automated operation, which not only facilitates use but also prevents the pusher cylinder from driving the pusher plate to move too far, ensuring operational stability. By setting the side of the pusher plate away from the pusher cylinder as an inclined surface, the inclined surface can be used to allow the raw material remaining on the pusher plate to flow. The guide design minimizes material loss caused by material stagnation on the pusher plate, reducing production costs. An annular scraper with a sealing ring on one side of the scraper effectively removes material from the inner wall of the metering channel, further reducing costs. The sealing ring prevents material from moving between the pusher plate and the pusher cylinder via the scraper, avoiding unnecessary losses or damage to the pusher cylinder caused by material falling onto the pusher rod, thus extending its service life. This extends the lifespan of the metering channel and reduces production costs. A heat insulation layer is installed on the outer wall of the metering channel, with multiple heating plates positioned between the insulation layer and the metering channel. These heating plates insulate the raw materials inside the metering channel, ensuring their flowability and facilitating subsequent material feeding. The heat insulation layer also prevents heat loss from the heating plates, maximizing the use of their heat energy to heat the internal environment of the metering channel, resulting in excellent energy savings. Furthermore, heat insulation layers are also adhered to the inner wall and bottom of the mounting groove, further enhancing heat insulation. The pressure sensor features overheat protection, extending its service life. Rounded corners at the connection between the discharge pipe and the metering channel ensure smoother material flow, preventing material stagnation and guaranteeing efficient feeding. Observation windows on both the storage tank and the metering channel allow operators to easily monitor material storage and output, facilitating timely addition of materials or adjustment of the pusher cylinder's start-up time. Therefore, this invention not only improves feeding accuracy but also offers advantages such as low labor intensity, high efficiency, long service life, low production cost, and ease of use.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example. A device for feeding silicone coatings with a quantitative function, configured as follows: Figures 1 to 3 As shown, the device includes a mounting frame 1 with upper, middle, and lower layers, and a storage tank 2 located on the upper layer of the mounting frame 1. A metering channel 3 is horizontally arranged in the middle layer of the mounting frame 1. An intermediate channel 4 connects the top surface of the metering channel 3 and the bottom surface of the storage tank 2. A gear pump 5 is installed on the intermediate channel 4. A pushing device is installed at one end of the metering channel 3, and a discharge pipe 6 is installed on the bottom surface of the other end. A pneumatic valve 7 is installed on the discharge pipe 6. An installation groove is provided on the inner bottom surface of the metering channel 3 between the pushing device and the discharge pipe 6. A pressure sensor 8 is installed in the installation groove. A controller 9 is installed on the mounting frame 1. The gear pump 5, the pushing device, the pneumatic valve 7, and the pressure sensor 8 are all electrically connected to the controller 9.

[0018] The feeding device includes a feeding cylinder 10 mounted on a mounting frame 1, and a feeding rod 11 mounted on the feeding cylinder 10. The end of the feeding rod 11 is connected to a feeding plate 12 located within the metering channel 3. A limit baffle 13 is provided on the end of the feeding rod 11 near the feeding cylinder 10, and the height of the limit baffle 13 is greater than the height of the metering channel 3. A mounting groove is also provided on the end face of the metering channel 3 near the feeding cylinder 10, and a piezoelectric sensor 14 is installed in the mounting groove. The piezoelectric sensor 14 is electrically connected to the controller 9. The side of the feeding plate 12 away from the feeding cylinder 10 is inclined, and a sealing ring 15 is adhered to the outer surface of the feeding plate 12. An annular scraper 16 is provided on the outer side of the metering channel 2, and the annular scraper 16 is located on the side of the sealing ring 15 away from the pushing cylinder 10; the outer wall of the metering channel 3 is covered with a heat insulation layer 17, and multiple evenly distributed electric heating plates 18 are provided between the heat insulation layer 17 and the metering channel 3; all electric heating plates 18 are electrically connected to the controller 9; the inner wall and inner bottom surface of the mounting groove are also covered with a heat insulation layer 17; the discharge pipe 6 is provided with a rounded corner at the position corresponding to the connection with the metering channel 3; the side of the storage tank 2 is provided with a transparent observation window 19; the side of the metering channel 3 is also provided with a transparent observation window 19 at the position above the discharge pipe 6.

[0019] Working Principle: During operation, the entire device is first placed on a horizontal surface. Then, raw materials for producing silicone coatings are added to the storage tank 2. Next, the device is connected to an external safe mains power supply, energizing the controller 9, pressure sensor 8, and piezoelectric sensor 14. (The controller 9 used in this invention can be an FX2C-20MRD, Cortex-R8, or Cortex-M7 model; the pressure sensor 8 can be a PX309-200A5V, PXM600MU-350BARGV, or PXM600MU-70BARGV model; all piezoelectric sensors...) 14. Specifically, models such as Y-YD-7051, CYB15, or CYZ102 can be used. Then, the weight of the required raw material is input through the control panel on the controller 9, which stores it as a standard value. Next, the controller 9 first controls the gear pump 5 to start. After the gear pump 5 starts, it will drive the raw material in the storage tank 2 from the middle channel 4 into the metering channel 3. When the raw material enters the metering channel 3, the pressure sensor 8 on the bottom surface of the metering channel 3 will weigh the raw material entering the metering channel 3 and send the weighing data to the controller 9. The controller 9 compares the received data with the initial standard value.

[0020] When both are equal, controller 9 first stops gear pump 5; then controller 9 starts pusher cylinder 10 and opens pneumatic valve 7. After pusher cylinder 10 starts, it drives pusher rod 11 to move towards discharge pipe 2. After pusher rod 11 moves, it drives pusher plate 12 to move towards discharge pipe 2. Pusher plate 12 pushes the raw material inside metering channel 3 from one side, so that the raw material inside can enter the discharge pipe 6 more quickly and flow to the next station. During the movement of pusher rod 11, limit baffle 13 moves together with it. When limit baffle 13 moves with metering... When the end face of channel 3 contacts, the limit baffle 13 will sense the piezoelectric sensor 14, causing the piezoelectric sensor 14 to generate an electrical signal to the controller 9. At this time, the controller 9 will control the pusher cylinder 10 to pause for a certain period of time (about 3 to 5 seconds). After the pause time is up, the controller 9 will control the pusher cylinder 10 to start again, causing the pusher cylinder 10 to drive the pusher rod 11 to move away from the discharge pipe 6. After the pusher rod 11 moves, it will drive the pusher plate 12 and the limit baffle 13 to move together, finally causing the pusher plate 12 to return to the initial position, completing the unloading operation.

[0021] During the process of conveying raw materials from the storage tank 2 to the metering channel 3, in order to ensure the flowability of the internal raw materials, the electric heating plate 18 can be powered on by the controller 9. The heat generated by the electric heating plate 18 is used to heat the internal raw materials through the inner wall of the metering channel 3. The setting of the heat insulation layer 17 can prevent the heat generated by the electric heating plate 18 from being transferred to the external environment, so that the heat can be transferred to the raw materials through the metering channel 3, thus improving the heat utilization rate. The setting of the observation window 19 on the storage tank 2 and the metering channel 3 allows the operator to easily observe the output of raw materials in the storage tank 2 and the discharge status of raw materials in the metering channel 3 during the feeding process, so that the operator can add raw materials in time or control the start and stop time of the pusher cylinder 10 through the controller 9.
