Description
Technical Field
[0001] This utility model relates to the field of quality testing technology, specifically to a quality testing device for silica sol products. Background Technology
[0002] Silica sol, as an important fine chemical product, has a wide range of applications in many fields. In the coatings industry, it is used to improve the adhesion, water resistance and hardness of coatings. Traditional silica sol quality testing methods mainly rely on manual experience and simple chemical analysis methods. For example, the quality is initially judged by observing the appearance, color and transparency of silica sol, and its silica content is determined by chemical titration.
[0003] Among the tests, density testing is required for silica sol products. However, due to potential differences in composition and properties between silica sol products from different manufacturers, existing testing devices often lack good compatibility and cannot easily test the density of silica sol products of various sizes. They also cannot effectively utilize pressure sensors to first detect the pressure value and then calculate the density. Furthermore, traditional equipment can often only test the density of the outer wall of the silica sol product and cannot effectively penetrate into multiple locations inside the silica sol product for testing, thus its practicality needs to be improved.
[0004] In view of this, we propose a quality testing device for silica sol products. Utility Model Content
[0005] The purpose of this invention is to provide a silica sol product quality testing device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A silica sol product quality testing device includes a machine base, and the machine base is equipped with a testing component, which includes:
[0008] A vertical rod is fixedly installed on the top of the machine base. A top plate is fixedly installed on the top of the vertical rod. A top asynchronous motor is fixedly installed in the middle of the top of the top plate. A vertical threaded rod is fixedly installed at the bottom output end of the top asynchronous motor. The vertical threaded rod is rotatably installed on the machine base. The vertical threaded rod is threadedly installed in the center of the U-shaped frame. The U-shaped frame slides against the arc-shaped outer wall of the vertical rod.
[0009] A servo hydraulic cylinder is provided, wherein servo hydraulic cylinders are fixedly installed at both ends of the U-shaped frame, and a piston rod is slidably arranged inside the servo hydraulic cylinder. There are two sets of servo hydraulic cylinders and piston rods, one set of which has an arc-shaped plate fixedly installed on the outer wall of the piston rod, and the other set of which has an L-shaped plate fixedly installed on the outer wall of the piston rod.
[0010] An asynchronous motor is fixedly installed on the top of the L-shaped plate. A rotating shaft is fixedly installed at the bottom output end of the asynchronous motor. A heater is fixedly installed at the bottom of the rotating shaft. A conical head is fixedly installed on the outer wall of one end of the heater. An electric heating wire is provided on the heater and is attached to the inside of the conical head. A connecting rod is fixedly installed at the other end of the heater, and a pressure sensor is fixedly installed at the other end of the connecting rod.
[0011] Preferably, two sets of vertical rods are provided, which makes the movement of the U-shaped frame more stable.
[0012] Preferably, the conical head is conical, and the area of the circular cross-section at the end of the conical head near the heater is larger than the area of the circular cross-section at the end away from the heater, and the conical head and the connecting rod are perpendicular to each other.
[0013] Preferably, the arc-shaped plate, the conical head, and the pressure sensor are all at the same horizontal level, which allows for better detection of the density of the silica sol product.
[0014] Preferably, a fixing component is provided on the top of the machine base. The fixing component includes a bracket. The bracket is fixedly installed on the top of the machine base. A bottom asynchronous motor is fixedly installed on the outer wall of the bracket. A bidirectional threaded rod is fixedly installed on the output end of the bottom asynchronous motor. The bidirectional threaded rod is rotatably installed on the bracket. A threaded block is threadedly installed on the bidirectional threaded rod. One end of the threaded block slides against the inner wall of the bracket. A clamping plate is fixedly installed on the other end of the threaded block.
[0015] Preferably, there are two sets of threaded blocks and clamping plates, and both sets of threaded blocks and clamping plates are mirror images of each other at both ends of the bracket with the vertical center line of the bracket as the mirror axis, so as to clamp and fix the bottom end of the silica sol product, and thus enable it to be tested more stably.
[0016] Compared with the prior art, this utility model provides a device for quality testing of silica sol products, which has the following beneficial effects:
[0017] 1. This silica sol product quality testing device, in order to better detect the density of the silica sol product body, is equipped with a detection component, in conjunction with a vertical rod and a top plate. When the asynchronous motor at the top is started, the vertical threaded rod rotates, allowing the U-shaped frame to move up and down. In conjunction with a servo hydraulic cylinder, piston rod, and arc plate, one side of the silica sol product body can be firmly fixed. In conjunction with an L-shaped plate, heater, conical head, and heating wire, a detection hole can be melted into the silica sol product body at the location to be tested. Then, the asynchronous motor is started, and the rotating shaft causes the connecting rod to drive the pressure sensor to rotate into the detection hole. The pressure value data is then converted into a density value, thereby enabling better detection of the density of the silica sol product body.
[0018] 2. This silica sol product quality testing device, in order to better fix silica sol products of various sizes for more stable testing, is equipped with a fixing component. When the asynchronous motor at the bottom of the support is started, the bidirectional threaded rod rotates, thereby causing the two sets of threaded blocks to move closer to each other, and the two sets of clamping plates to move closer to each other to clamp and fix the bottom of the silica sol product, thus enabling more stable testing and improving applicability.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution:
[0027] A silica sol product quality testing device includes a machine base 1 for placing silica sol products.
[0028] In one embodiment of this utility model, a detection component 2 is provided on the machine base 1. The detection component 2 includes a vertical rod 21. The vertical rod 21 is fixedly installed on the top of the machine base 1. A top plate 22 is fixedly installed on the top of the vertical rod 21. A top asynchronous motor 23 is fixedly installed at the middle of the top of the top plate 22. A vertical threaded rod 24 is fixedly installed at the bottom output end of the top asynchronous motor 23. The vertical threaded rod 24 is rotatably installed on the machine base 1 and threadedly installed at the center of a U-shaped frame 25. The U-shaped frame 25 slides against the arc-shaped outer wall of the vertical rod 21. In addition, two sets of vertical rods 21 are provided to make the movement of the U-shaped frame 25 more stable. Servo hydraulic cylinders 26 are fixedly installed at both ends of the U-shaped frame 25. A piston rod 27 is slidably arranged inside the servo hydraulic cylinder 26. Two sets of servo hydraulic cylinders 26 and piston rods 27 are provided. An arc-shaped plate 28 is fixedly installed on the outer wall of one set of piston rods 27, and an L-shaped plate is fixedly installed on the outer wall of the other set of piston rods 27. 29. An asynchronous motor 210 is fixedly installed on the top of the L-shaped plate 29. A rotating shaft 211 is fixedly installed at the bottom output end of the asynchronous motor 210. A heater 212 is fixedly installed at the bottom of the rotating shaft 211. A conical head 213 is fixedly installed on the outer wall of one end of the heater 212. An electric heating wire 214 is provided on the heater 212 and is attached to the inside of the conical head 213. A connecting rod 215 is fixedly installed at the other end of the heater 212. A pressure sensor 216 is fixedly installed at the other end of the connecting rod 215. In addition, the conical head 213 is conical, and the area of the circular cross-section of the end of the conical head 213 near the heater 212 is larger than the area of the circular cross-section of the end away from the heater 212. The conical head 213 and the connecting rod 215 are perpendicular to each other. Furthermore, the arc plate 28, the conical head 213, and the pressure sensor 216 are all at the same horizontal level, which can better detect the density of the silica sol product body.
[0029] In this embodiment, the operator places the silica sol product to be tested at the designated position on the machine 1 to prepare for subsequent testing. The operator then starts the top asynchronous motor 23 mounted on the top of the top plate 22, which drives the vertical threaded rod 24 to rotate. Driven by the vertical threaded rod 24, the U-shaped frame 25 begins to move up and down along the direction of the vertical rod 21. The operator, through observation or with the aid of relevant control equipment, adjusts the U-shaped frame 25 to a suitable position that matches the height of the silica sol product. A set of servo hydraulic cylinders 26 mounted at both ends of the U-shaped frame 25 is then activated, pushing the piston rod 27 outwards. The piston rod 27 drives the arc-shaped plate 28 to move laterally, gradually bringing the arc-shaped plate 28 closer to one side of the silica sol product body. The product is held firmly against the silica sol, securing it from the side to prevent displacement during subsequent testing. The heater 212, installed at the bottom of the rotating shaft 211, is then activated. Once powered on, current flows through the heating wire 214, which is tightly fitted inside the conical head 213. According to Joule's law, when current passes through the heating wire 214, which has a certain resistance, work is done, and electrical energy is converted into heat energy, causing the temperature of the heating wire 214 to rise rapidly. Because the heating wire 214 is tightly fitted inside the conical head 213, heat is quickly transferred to the conical head 213, raising its temperature. The heated conical head 213 is then moved to the position on the silica sol product body to be tested, utilizing its high temperature to... The silica sol product is melted to create a detection hole, preparing for the subsequent entry of the pressure sensor 216 for detection. After the hole is melted, another set of servo hydraulic cylinders 26 is operated in reverse by the control equipment to move the conical head 213 away from the detection hole position. The asynchronous motor 210 is started, and its output end drives the rotating shaft 211 to rotate 90 degrees. The rotating shaft 211 drives the pressure sensor 216 to rotate 90 degrees through the connecting rod 215, so that the detection end of the pressure sensor 216 is aligned with and enters the previously melted detection hole. The same set of servo hydraulic cylinders 26 is operated again, moving the connecting rod 215 to make the pressure sensor 216 penetrate further and press tightly against the interior of the silica sol product body. Different density silica sol products apply different pressure values to the pressure sensor 216. The pressure sensor 216 converts the sensed pressure signal into an electrical signal output. These electrical signals are transmitted to the data processing equipment through the connection line. The data processing equipment uses existing technology and the algorithm preset in the equipment to convert the pressure value data into a density value, and finally completes the detection of the density of the silica sol product. (It is worth noting that the specific conversion method is existing technology and existing equipment, so it will not be described in detail here.) After one detection is completed, the top asynchronous motor 23 is started, so that the detection point can move up and down, and thus can better penetrate into multiple locations inside the silica sol product for detection, improving practicality.
[0030] In one embodiment of this utility model, a fixing component 3 is provided on the top of the machine base 1. The fixing component 3 includes a bracket 31. The bracket 31 is fixedly installed on the top of the machine base 1. A bottom asynchronous motor 32 is fixedly installed on the outer wall of the bracket 31. A bidirectional threaded rod 33 is fixedly installed on the output end of the bottom asynchronous motor 32. The bidirectional threaded rod 33 is rotatably installed on the bracket 31. A threaded block 34 is threadedly installed on the bidirectional threaded rod 33. One end of the outer wall of the threaded block 34 slides against the inner wall of the bracket 31. A clamping plate 35 is fixedly installed on the other end of the outer wall of the threaded block 34. In addition, there are two sets of threaded blocks 34 and clamping plates 35. Both sets of threaded blocks 34 and clamping plates 35 are mirror images of the vertical center line of the bracket 31 and are mirror images of the two ends of the bracket 31, thereby clamping and fixing the bottom end of the silica sol product, so that it can be tested more stably.
[0031] In this embodiment, the operator starts the bottom asynchronous motor 32 on the bracket 31, which drives the bidirectional threaded rod 33 to rotate. The two ends of the bidirectional threaded rod 33 have threads with opposite directions of rotation, which respectively cooperate with two sets of threaded blocks 34. One end of the two sets of threaded blocks 34 slides against the inner wall of the bracket 31, and the other end is fixed with a clamping plate 35. When the bidirectional threaded rod 33 rotates, due to the transmission effect of the threads, the two sets of threaded blocks 34 move closer to each other along the inner wall of the bracket 31. The movement of the threaded blocks 34 drives the two sets of clamping plates 35 to move closer to each other. The clamping plates 35 gradually approach the bottom end of the silica sol product placed on the machine base 1. After the clamping plates 35 contact the silica sol product, a certain pressure is applied to firmly clamp the bottom end of the silica sol product, so that the product can remain stable during the testing process and will not shake or shift, thus accepting the test more stably.
[0032] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device capable of controlling the top asynchronous motor 23, servo hydraulic cylinder 26, asynchronous motor 210, heater 212, pressure sensor 216, and bottom asynchronous motor 32. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding, which are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
