Description

Technical Field

[0001] The invention relates to the field of defoaming masterbatch detection equipment setting, in particular to defoaming masterbatch raw material production detection equipment and a detection method based on the fluid viscosity principle. Background Art

[0002] In the process of preparing defoaming masterbatch, a variety of raw materials are needed, and for some raw materials, their physical states are different. For the properties of raw materials, including powdery substances and fluids, the ultimate purpose of preparing defoaming masterbatch is to ensure that the raw materials are fully mixed, so as to ensure that the prepared defoaming purpose meets the preparation standards. In the process of preparing defoaming masterbatch, it is necessary to go through the steps of mixing, extrusion, cooling, drying, and granulation, and the most basic step that has the greatest impact on the product quality of defoaming masterbatch is the mixing extrusion step. Because when preparing the defoaming purpose, it is necessary to add a variety of raw materials into the mixing chamber of the extruder, and stir the raw materials through the stirring device arranged in the extruder. After the mixing is completed, the auger rod arranged inside the extruder transfers the prepared mixture and extrude it outward at the port position of the extruder, thereby obtaining the defoaming purpose strip. However, the raw materials of the defoaming masterbatch contain water, and some water exists in the form of crystal water. Under certain reaction conditions, crystal water will precipitate, and the high temperature and high pressure extruder environment can meet some crystal water precipitation conditions. In addition, during the extrusion process of the raw materials of the defoaming masterbatch, the moisture generated inside it will separate from some of the raw materials, which will reduce the strength of the mixed base material after the binder of the raw materials is mixed with the powdered base material in the mixing chamber. Moreover, after the defoaming masterbatch is cooled and hardened, smaller bubbles will be generated inside it.

[0003] Therefore, in the high temperature and high pressure environment of the extruder, the crystal water of some raw materials can be effectively destroyed. However, after the defoaming masterbatch is extruded and hardened, the operating environment of the extruder and the raw materials cannot be corrected in time, which brings certain losses to the company's production (because the defoaming masterbatch needs a certain amount of time in the cooling, deformation and drying process, and during this time, the port holes of the extruder can extrude a lot of defoaming masterbatch, resulting in material waste). As for the solid-liquid mixture of raw materials, it itself has fluid viscosity. Therefore, according to the principle of fluid viscosity, the defoaming masterbatch mixture in the extruder is quality tested to detect whether the obtained mixture meets the viscosity of the standard mixture, so as to determine whether the extruder and raw materials need to be corrected.

[0004] Based on the above problems, it is necessary to carry out production testing equipment and testing methods for defoaming masterbatch raw materials based on the principle of fluid viscosity. The solid-liquid mixture inside the extruder can be tested according to the principle of fluid viscosity, and then it can be determined whether the viscosity of the mixture during extrusion meets the standard, so that the defoaming masterbatch obtained in subsequent production can meet the production standards and avoid the problem of unqualified production. Summary of the invention

[0005] The purpose of the present invention is to provide a defoaming masterbatch raw material production detection equipment based on the fluid viscosity principle, which can avoid the problem of mixing the mixed material, resulting in the extruded material in the defoaming masterbatch containing more water, thereby avoiding the problem of bubbles appearing inside the defoaming masterbatch after the subsequent drying treatment of the defoaming masterbatch, thereby ensuring that the enterprise has good production benefits and avoiding the problem of large production losses.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] The invention discloses a production detection device for defoaming masterbatch raw materials based on the fluid viscosity principle, including a detection structure assembly, which is arranged in cooperation with the extrusion channel position of the extruder; the detection structure assembly includes two detection parts and a docking ring, and the two detection parts are respectively arranged at the two end positions of the docking ring, and are connected to the extrusion channel through the docking ring; a detection position is set on the docking ring, and the detection part is arranged in cooperation with the detection position, and the detection part is connected to a PLC integrated mainboard, and the data information obtained by the detection of the detection part is processed by the PLC integrated mainboard.

[0008] The detection member is a port detection structure component or a channel detection structure component, and the port detection structure component or the channel detection structure component is arranged in cooperation with the detection position on the docking ring.

[0009] The channel detection structure component includes a center ring and a docking rotor, the docking rotor abuts against the center ring, and the rotation shaft of the docking rotor is connected to an angle sensor component, and the angle sensor component is connected to the PLC integrated mainboard.

[0010] The center ring includes a soft outer ring sleeve and a center double helical shaft. The inner end of the center double helical shaft is provided with a semicircular slideway reinforcement rib. The soft outer ring sleeve is arranged around the center double helical shaft and the semicircular slideway reinforcement rib.

[0011] The detection position is an arc installation position, the center ring limiter is arranged inside the arc installation position, and the semicircular slideway reinforcement rib is arranged at a position close to the central axis of the docking ring.

[0012] The port detection structural component includes a pressure detection member and a sliding end block. The sliding end block and the pressure detection member are arranged in cooperation with each other, and when the sliding end block contacts the mixed material, pressure is applied to the pressure detection member.

[0013] The detection position is an end block slot, the pressure detection component is fixedly arranged inside the end block slot, and the pressure detection component is connected to the PLC integrated mainboard; the sliding end block is arranged inside the end block slot, and the outer end face of the sliding end block is an outward convex arc surface structure.

[0014] The detection method of the defoaming masterbatch raw material production detection equipment based on the fluid viscosity principle includes the following steps:

[0015] S1, docking a detection collar equipped with different detection components with different positions inside the extrusion channel to detect the fluid viscosity of the mixture;

[0016] S2, the detection rings with channel detection structure components installed at the detection positions on both sides are connected to the inside of the extrusion channel. When the mixed material in the extrusion channel passes through the channel detection structure component, the mixed material contacts the soft outer ring sleeve of the center ring, so that the mixed material drives the soft outer ring sleeve to move, and drives the docking rotor to rotate, so that the angle sensor component detects the rotation data of the docking rotor, and transmits the data to the PLC integrated mainboard for digital-to-analog conversion, and obtains the specific data of the rotation of the docking rotor at this time, so that the PLC integrated mainboard obtains the rotation angle change of the docking rotor in real time; at this time, the soft outer ring sleeve transmits the force to the central double helical shaft, so that the central double helical shaft rotates in the semicircular slideway reinforcement rib, providing conditions for the rotation of the soft outer ring sleeve;

[0017] S3, the detection rings on both sides of the detection position respectively installed with the channel detection structure component and the port detection structure component are connected to the inside of the extrusion channel, so that the detection ring close to the port detection structure component is connected to the outlet end of the extrusion channel; when the mixture inside the extrusion channel passes through the channel detection structure component, the mixture contacts the soft outer ring sleeve of the center ring, so that the mixture drives the soft outer ring sleeve to move, and drives the docking rotor to rotate, so that the angle sensor component detects the rotation data of the docking rotor, and transmits the data to the PLC integrated mainboard for digital-to-analog conversion, and obtains the specific data of the rotation of the docking rotor at this time, so that the PLC integrated mainboard obtains the rotation angle change of the docking rotor in real time; at this time, the soft outer ring sleeve transmits the force to the central double helical shaft, so that the central double helical shaft rotates in the semicircular slideway reinforcement rib, providing conditions for the rotation of the soft outer ring sleeve;

[0018] When the mixture inside the extrusion channel passes through the port detection structure component, at this time the mixture comes into contact with the inner end face of the sliding end block, causing the mixture to exert a force on the inner end face of the sliding end block and transmitting the force to the pressure detection component. The pressure detection component transmits the detection data to the PLC integrated main board, enabling the PLC integrated main board to perform digital-to-analog conversion on the detection data of the pressure detection component, so that the PLC continuously obtains the pressure value change of the sliding end block on the pressure detection component;

[0019] S4. Analyze and monitor the implementation data obtained by the PLC integrated main board. When the data expressed by the PLC integrated main board shows abnormal changes, the staff analyzes the components that transmit abnormal information to the PLC integrated main board, and then solves the factors affecting the change in the viscosity of the mixture.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] When setting up this device, by setting the detection component on the docking collar, and for the setting method of the detection component on the docking collar, the specific structure of the detection component is determined according to the application environment.

[0022] 1. For the mixture inside the extrusion channel, since the mixture here needs to pass through the high-temperature and high-pressure part inside the extruder after being stirred in the stirring chamber. In view of this application environment, the detection component is set, that is, the mixture drives the soft outer ring sleeve of the central ring to deform and rotate, so that the soft outer ring sleeve drives the docking rotating head in contact with it to rotate, and when the docking rotating head rotates, it can still drive the angle sensing component to sense the rotation angle information, and then transmit the information to the PLC integrated main board. Because the force that the standard mixture viscosity can drive the soft outer ring sleeve is determined, when the viscosity of the mixture changes, there will be a problem of abnormal movement of the driven soft outer ring sleeve, so as to judge whether the viscosity of the mixture passing through the detection component meets the standard.

[0023] 2. For the mixture to be extruded from the extrusion channel, since the temperature and pressure of the mixture have decreased at this time, when detecting the viscosity of the mixture at this time, it is necessary to adapt to this environment for structural setting. Here, the detection component is set as a pressure detection component and a sliding end block. When a force is generated between the mixture and the sliding end block, the sliding end block transmits the force generated by the mixture to the pressure detection component, so that the pressure detection component detects the magnitude of the force exerted by the mixture on the sliding end block. And for the mixture with a large standard viscosity, the force on the sliding end block is certain. Therefore, here, the data information detected by the pressure detection component is used to judge whether the viscosity of the mixture passing through the sliding end block meets the standard.

[0036] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0037] As is known to all, the viscosity of a fluid refers to the property that when the fluid moves, internal friction is generated between the micro-groups or flow layers inside the fluid due to the relative motion to prevent the fluid from making relative motion. Obviously, any actual fluid is viscous. The magnitude of its viscosity can be reflected by the different abilities of different fluids to resist relative motion. For example, when the raw materials inside the defoaming masterbatch are mixed unevenly, the transferred mixture will have more solids or more fluids at a certain point in time, causing the friction force value generated on the inner wall of the extruder 1 to change at this time, and the structural components set as follows can detect and judge the friction force, thereby judging whether the mixed raw materials of the defoaming masterbatch are mixed evenly.

[0038] Firstly, for the raw materials for preparing defoaming masterbatch, when the liquid and the powder solid are mixed, it is necessary to ensure that the raw materials are mixed evenly, so as to ensure that the prepared defoaming masterbatch meets the production standards. However, whether it is the processing environment problem given by the extruder 1 or the mixing problem of the raw materials themselves, it will affect the viscosity of the mixed material after the raw materials are mixed, so that the defoaming masterbatch produced no longer meets the production standards. Therefore, the following settings are made for the use environment:

[0039] The present invention is a production detection device for defoaming masterbatch raw materials based on the principle of fluid viscosity, including a detection structure assembly, which is arranged in conjunction with the extrusion channel position of the extruder 1; the detection structure assembly includes two detection parts 2 and a docking ring 3, and the two detection parts 2 are respectively arranged at the two end positions of the docking ring 3, and are connected to the extrusion channel through the docking ring 3; firstly, for the docking ring 3, the purpose is to dock with the extrusion channel of the extruder 1, and it is arranged according to different use environments to meet the docking requirements of the docking ring 3 in different environments. Secondly, for the detection part 2, it needs to be arranged according to different use environments, because the viscosity of the mixture under different conditions in the extruder 1 is different, so it is necessary to arrange the detection part 2 according to the viscosity of the mixture at different ambient temperatures, so as to meet the detection part 2 to detect the viscosity of the mixture under different environments and avoid the problem of misdetection. At the same time, because the detection component 2 needs to be installed and set, and the specific data detected by the detection component 2 needs to be obtained, a detection position 4 is set on the docking ring 3 during the setting here, and the detection component 2 is cooperatively set at the detection position 4, and the detection component 2 is connected with a PLC integrated mainboard, and the data information detected by the detection component 2 is processed by the PLC integrated mainboard; here, the detection position 4 is set on the docking ring 3 to facilitate the installation of the docking ring 3, and the detection component 2 is connected to the PLC integrated mainboard, and then when the detection component 2 detects and obtains the data information, the data information is transmitted to the PLC integrated mainboard, so that the PLC integrated mainboard performs digital-to-analog conversion on the data information transmitted by the detection component 2, thereby obtaining the specific data transmitted by the detection component 2. As for the reason why the two detection members 2 need to be respectively set at the two end positions of the docking ring 3 when setting the detection member 2, it is to ensure that the detection member 2 obtains the first detection data of the mixture at the detection position 4 that it first passes through, and the first detection data may be affected by many factors. Therefore, after setting the two detection members 2, it is possible to avoid the problem of changes in the detection results caused by some other factors. For example, when the mixture inside the mixing chamber cannot effectively advance forward, it will cause the mixture to be unable to advance forward, thereby changing the detection result of the angle sensor assembly 9. Therefore, two detection members 2 are set here to eliminate the influence of some other factors on the detection.

[0040] As for the detection member 2, the detection member 2 is a port detection structure component 5 or a channel detection structure component 6, and the port detection structure component 5 or the channel detection structure component 6 is arranged in cooperation with the detection position 4 on the docking ring 3. The port detection structure component 5 and the channel detection structure component 6 arranged here are arranged according to the environment where the mixture is located, because the temperature and pressure to which the mixture is subjected inside the extruder 1 are different, and therefore different types of detection members 2 are arranged for detection to adapt to the different environments where the mixture is located, so as to detect whether the viscosity of the mixture in different environments meets the standard, and facilitate the staff to make timely adjustments according to the detection information.

[0041] First use environment:

[0042] For the first use environment, it is at the position connected to the auger rod in the mixing chamber of the extruder 1, because the auger rod here only transports the mixture forward in the extrusion chamber of the extruder 1, and no longer stirs the mixture, so the mixture sample here is a mixture sample that is no longer mixed. The mixture at this position has a standard viscosity value, that is, the viscosity value of the mixture after the mixture is uniformly mixed under the standard corresponding environment of ambient temperature. When the viscosity of the mixture detected at this stage is significantly different from the standard viscosity value, it means that there are problems in the mixing and adding of raw materials, so the inspection is carried out according to the structure obtained by the detection to solve the problem affecting the viscosity of the mixture.

[0043] First, the structural settings in this environment are described:

[0044] Because when the mixed material passes through the extruder 1, a certain extrusion force is generated between the mixed material and the inner wall of the extruder 1 at this time, thereby causing friction between the mixed material and the inner wall of the extruder 1, but the friction caused by materials of different viscosities is different. Therefore, it is necessary to set up a channel detection structure component 6, that is, the channel detection structure component 6 includes a center ring 7 and a docking turntable 8, the docking turntable 8 abuts against the center ring 7, and the rotating shaft of the docking turntable 8 is connected with an angle sensor component 9, and the angle sensor component 9 is connected to the PLC integrated motherboard; first, when the mixed material is extruded through the extrusion channel, the viscosity of the mixed material at this time is relatively large, so the adhesion problem between the detection member 2 and the mixed material should be avoided. Therefore, when setting up here, by setting the channel detection structure component 6 to include a center ring 7 and a docking end, the mixed material can drive the center ring 7 to rotate relative to the position of the detection position 4. It should be noted here that when the center ring 7 rotates, it does not rotate with the central axis of the extrusion channel, but rotates with the transmission direction toward the central axis of the extrusion channel, that is, when the mixed material passes through the center ring 7, it drives the center ring 7 to move. After the center ring 7 rotates, the docking rotor 8 abuts against the center ring 7, so that the center ring 7 drives the docking rotor 8 to rotate, and the angle sensor component 9 connected to the rotating shaft of the docking rotor 8 transmits the rotation information of the docking rotor 8 to the PLC integrated mainboard, so that the PLC integrated mainboard receives the detection signal of the angle sensor component 9, and then the PLC integrated mainboard performs digital-to-analog conversion on the received detection signal, thereby obtaining the final detection data.

[0045] In the above description, if the central ring 7 is a single structure, then the central ring 7 cannot rotate toward the central axis of the extrusion channel. Therefore, the central ring 7 needs to be set here, that is, the central ring 7 includes a soft outer ring sleeve 10 and a central double helical shaft 11. The inner end of the central double helical shaft 11 is provided with a semicircular slideway reinforcement rib 12. The soft outer ring sleeve 10 is arranged around the central double helical shaft 11 and the semicircular slideway reinforcement rib 12. As shown in the attached figure of the specification Figure 6 As shown, it is a schematic diagram of the structure of the central double helical shaft 11. When setting, the central double helical shaft 11 is set in contact with the semicircular slideway reinforcement rib 12. After setting the central double helical shaft 11, the beneficial effects that can be achieved are as follows:

[0046] 1. For the material of the central double helical shaft 11, if the preparation material of the central double helical shaft 11 is a rigid material, then the central double helical shaft 11 cannot be rotated, so the preparation material of the central double helical shaft 11 here should be a deformable material. However, the central double helical shaft 11 itself here also needs to be supported on both the inside and outside, so a double helical structure is selected for setting, that is, the surrounding positions of the double helical structure can be supported outward, so that the force of the central double helical shaft 11 can be uniform, and there will be no problem of collapse and depression at a certain position, thereby ensuring that the central double helical shaft 11 can be driven by the soft outer ring sleeve 10 to rotate. It should be noted here that because the inner diameter and outer diameter of the central double helical shaft 11 are different from the center distance of the extrusion channel, when the central double helical shaft 11 rotates here, there will be a situation where the position between the inner diameter and the outer diameter is replaced, so that the central double helical shaft 11 causes extrusion pressure on the inside. Therefore, it is necessary to set a semicircular slide reinforcement rib 12 at the inner end position of the central double helical shaft 11, so that the deformation of the central double helical shaft 11 toward the center position can be overcome under the reinforcement of the semicircular slide reinforcement rib, and the central ring 7 can be prevented from being separated from the detection position 4 due to the deformation of the central double helical shaft 11, which will cause disadvantages in the use of the device.

[0047] Because in the use environment inside the extruder 1, the mixture is generally moved forward at a uniform speed by the auger, and the mixture begins to be compressed after entering the extrusion channel, so the force transmitted by the mixture to the inner end position of the center ring 7 is also consistent, causing the inner end position of the center ring 7 to have a movement trend to move with the mixture. Therefore, the soft outer ring sleeve 10 is provided with deformation ability, that is, the shape of the soft outer ring sleeve 10 can be changed when it rotates, thereby providing a basis for the soft outer ring sleeve 10 to drive the central double helical shaft 11 to rotate.

[0048] 2. Because when setting the center ring 7 here, it is necessary to ensure that the elastic deformation of the soft outer ring sleeve 10 mounted on the center ring 7 is minimized, that is, to ensure that the deformation of the soft outer ring sleeve 10 except for rotation is minimized. A universal bearing is used here to fit the soft outer ring sleeve 10. Although there is no need to worry about the deformation of the universal bearing, the shape of the universal bearing will affect the deformation degree of the soft outer ring sleeve 10, causing the soft outer ring sleeve 10 to become uneven. As a result, after the soft outer ring sleeve 10 abuts against the docking rotor 8, the docking rotor 8 may not be able to rotate effectively due to the deformation of the soft outer ring sleeve 10. The central double helix shaft 11 can ensure that under the support of the double helix structure, the soft outer ring sleeve 10 will not have serious deformation problems, and further ensure that the soft outer ring sleeve 10 will not have unevenness when it can deform and rotate, so that the soft outer ring sleeve 10 can effectively abut against the docking rotor 8, and there will be no relative sliding problem between the docking rotor 8 and the soft outer ring sleeve 10.

[0049] And after the soft outer ring sleeve 10 provided here abuts against the docking swivel 8, because there is a force between the docking swivel 8 and the soft outer ring sleeve 10, if a universal bearing is used for setting here, the universal bearing will move in both directions, so that the docking swivel 8 will still be unable to effectively abut against the soft outer ring sleeve 10. The central double helical shaft 11 can ensure that the soft outer ring sleeve 10 is effectively supported outward, so that the soft outer ring sleeve 10 can effectively abut against the docking swivel 8, and there will be no problem of being unable to effectively abut against the docking swivel 8 due to the elastic deformation of the soft outer ring sleeve 10, ensuring that the docking swivel 8 can be effectively driven to rotate while the soft outer ring sleeve 10 moves.

[0050] 3. Because when the mixture passes through the soft outer ring sleeve 10, the soft outer ring sleeve 10 moves with the mixture, but when the mixture moves, the soft outer ring sleeve 10 cannot rotate around the center ring 7, that is, it cannot move in the direction of the front tangent of the center ring 7. Because not only will the soft outer ring sleeve 10 be excessively elastically deformed, causing the soft outer ring sleeve 10 to have wrinkles, thereby affecting the mixture to effectively drive the soft outer ring sleeve 10 to rotate, but also the soft outer ring sleeve 10 applies a force to the docking rotor 8 in the direction around the center ring 7, so that the friction force of the docking rotor 8 rotating in the axial direction increases, thereby affecting the normal rotation of the docking rotor 8 relative to the soft outer ring, so that when the soft outer ring sleeve 10 rotates normally, it is difficult to drive the docking to rotate, and when the force is too large, it will cause the soft outer ring sleeve 10 to be unable to effectively drive the docking rotor 8 to rotate, resulting in errors in the data obtained by the detection.

[0051] 4. When setting the position of the docking rotor 8, it should be ensured that the docking rotor 8 not only generates a force with the soft outer ring sleeve 10, but also generates a certain force with the central double helical shaft 11, so as to ensure that the central double helical shaft 11 can play a certain supporting role and avoid the problem of relative sliding between the central double helical shaft 11, the soft outer ring sleeve 10 and the docking rotor 8. And because the inner and outer diameters of the central double helical shaft 11 are exchanged and rotated, a force will be generated on the semicircular slideway reinforcement rib 12. Therefore, in order to avoid the problem that the central double helical shaft 11 transmits the force to the soft outer ring sleeve 10 due to the force generated when the inner and outer diameters are replaced, so that the soft outer ring sleeve 10 has a relative sliding problem, it is necessary to ensure that there is a large force between the soft outer ring sleeve 10 and the semicircular slideway reinforcement rib 12, so as to avoid the problem that when the inner and outer diameters of the central double helical shaft 11 are replaced and a force is generated, the force will not drive the soft outer ring sleeve 10 to slide relative to the semicircular sliding reinforcement rib. When relative position sliding occurs between the soft outer ring sleeve 10 and the semicircular sliding reinforcement rib, the soft outer ring sleeve 10 is not moved by the mixture, which will cause the docking rotor 8 to rotate abnormally, making the real-time detection result inaccurate, and making it impossible for the staff to find the factors that affect the change of the detection result.

[0052] Of course, in addition to the above-mentioned structural settings, the following further optimization is performed: the detection position 4 is an arc installation position 13, the center ring 7 is limitedly set inside the arc installation position 13, and the semicircular slideway reinforcement rib 12 is set at a position close to the central axis of the docking ring 3. Because the center ring 7 needs to be installed at the detection position 4 to ensure that the position of the center ring 7 relative to the extrusion channel does not change, it is necessary to ensure that the center ring 7 is effectively fixed at the detection position 4 and cannot affect the normal position movement of the soft outer ring sleeve 10 of the center ring 7, so the detection position 4 is set to the arc installation position 13; that is, as shown in the figure of the specification Figure 4As shown, the center ring 7 is installed in the arc installation position 13, so that the arc installation position 13 can limit the position of the center ring 7, and for the semicircular slideway reinforcement rib, its upper end position is inside the arc installation position 13, and the position of the semicircular slideway reinforcement rib is limited by the arc installation position 13, thereby avoiding the problem of position movement of the semicircular slideway reinforcement rib. And when setting the position of the docking turntable 8, the docking turntable 8 is set at the outer end position of the arc installation position 13 and the docking turntable 8 is abutted against the center ring 7, so that the position of the center ring 7 relative to the docking turntable 8 can be further limited, so that the soft outer ring sleeve 10 of the center ring 7 can be effectively rotated. And because of the setting of the arc mounting position 13, the soft outer ring sleeve 10 and the semicircular slideway reinforcement rib can be effectively fitted; and when the soft outer ring sleeve 10 contacts the mixture, some of the mixture will adhere to the soft outer ring sleeve 10, and when the soft outer ring sleeve 10 enters the arc mounting position 13, the lower end position of the arc mounting position 13 will scratch the mixture adhered to the soft outer ring sleeve 10, thereby preventing some of the mixture from entering the arc mounting position 13. Another advantage of the central double helix shaft 11 is also reflected here, because the central double helix shaft 11 can support the outer soft outer ring sleeve 10 in multiple directions, so that there will be no large gap problem between the soft outer ring sleeve 10 and the arc mounting position 13, thereby ensuring that the lower end of the arc mounting position 13 can more cleanly adhere to the mixture on the soft outer ring sleeve 10; and the central double helix shaft 11 is not prone to depression problems, thereby further ensuring the tightness of the fit between the soft outer ring sleeve 10 and the arc mounting position 13.

[0053] In the first use environment, because the mixture is in a state of stirring and transfer, and is not heated in the extruder 1, the mixture still contains crystal water at this time. In the process of passing through the extruder 1, the environment in which the mixture is located is heated and pressurized. Therefore, the viscosity of the mixture before mixing can show whether the mixture is mixed evenly. The viscosity of the mixture after the mixture is heated and pressurized by the extruder 1 is to detect the precipitation of crystal water inside the mixture, so as to ensure that after the mixture is prepared into defoaming masterbatch, the prepared defoaming masterbatch can meet the application requirements.

[0054] Second use environment:

[0055] For the second use environment, because the mixture passes through the high temperature stage inside the extruder 1, some crystal water is precipitated outward, thereby changing the viscosity of the mixture. Therefore, in the second use environment, by detecting the specific data value of the viscosity of the mixture, it is determined whether the crystal water precipitated in the unit mixture meets the precipitation standard, thereby ensuring that the prepared defoaming masterbatch can effectively meet the use requirements in subsequent use. However, in the second use environment, after passing through the heated tube wall in the extrusion channel, the temperature of the mixture will gradually decrease, causing the viscosity of the mixture to gradually increase, especially near the position of the outer port of the extrusion channel, where the viscosity of the mixture is relatively large, so here it is impossible to detect the viscosity of the mixture through the channel detection structure component 6, because the above-mentioned mixture can easily cause a blockage problem between the center ring 7 and the detection position 4, so the detection member 2 is set at the port position to meet the viscosity detection requirements of the mixture with greater viscosity.

[0056] Because the amount of crystal water that can be precipitated from a unit volume of mixed material under a specified temperature and pressure environment is certain, and the viscosity of the mixed material corresponding to the precipitated crystal water is also basically the same, it is necessary to detect the viscosity of the mixed material after the crystal water is precipitated. For the port detection structure component 5, when setting it up, the port detection structure component 5 is set to include a pressure detection component 14 and a sliding end block 15, and the sliding end block 15 is matched with the pressure detection component 14, and when the sliding end block 15 contacts the mixed material, it exerts pressure on the pressure detection component 14. As shown in the accompanying drawings of the specification Fig. 9As shown, by matching the pressure detecting component 14 and the sliding end block 15, when the mixture in the extrusion channel passes through the high-temperature area and is extruded outward, it passes through the sliding end block 15 provided here, and the mixture contacts the inner end surface of the sliding end block 15, so that the sliding end block 15 transmits the force exerted by the mixture to the pressure detecting component 14, and the pressure detecting component 14 obtains pressure data information. Because for the mixture, the viscosity after the crystallization water is precipitated under the specified temperature and pressure state is basically the same; when the mixture passes through the sliding end block 15, it will cause adhesion to the sliding end block 15, that is, in addition to the extrusion force applied toward the sliding end block 15, it also includes the adhesion force when leaving the sliding end block 15, and the adhesion force of the mixture that precipitates standard crystallization water to the sliding end block 15 is basically the same, so here when the pressure data detected by the pressure detection part 14 changes, it means that the adhesion force applied by the mixture to the sliding end block 15 at this time has changed (at this time, it is necessary to ensure that the extrusion rate of the mixture will not change significantly), and then judge whether the crystallization water precipitated under high temperature and high pressure environment meets the standard. For the pressure detection part 14 here, when setting, you can choose a piezoresistive element for setting, but when setting, you need to ensure that the piezoresistive element can be evenly stressed by the force applied by the mixture, so here when the matching relationship between the sliding end block 15 and the pressure detection part 14 is performed, the following setting methods are included:

[0057] 1. The sliding end block 15 is an annular end block, and a plurality of the pressure detection components 14 are arranged in a circular array inside the detection position 4, and each of the pressure detection components 14 is fixedly connected to the outer end surface of the annular end block. Here, for the annular end block, in order to realize that the entire annular end block can expand outward, when the annular end block is set here, it is necessary to set the annular end block to a soft elastic material, so that when the mixture squeezes the annular end block, the annular end block elastically deforms outward, thereby exerting pressure on the pressure detection component 14. When the unit volume of the mixture detaches from the annular end block, the annular end block at this time is subjected to the adhesion force when the unit volume of the mixture detaches, and then under the action of the adhesion force and the extrusion force, a constant pressure value detected by the pressure detection component 14 is obtained. The way of setting the sliding end block 15 as an annular end block can ensure that the inner end position of the annular end block can be subjected to the force of the mixture at each position, so that the annular end block transmits the force to the pressure detection component 14, so that the pressure detection component 14 obtains the force information of the mixture on the annular end block.

[0058] 2. The sliding end block 15 is a telescopic end block, and a plurality of the detection positions 4 are arranged in a circular array on the docking ring 3, and a telescopic end block is correspondingly arranged in each detection position 4, and a pressure detection member 14 is arranged at the inner end of the detection position 4, and the pressure detection member 14 is connected to the inner end of the telescopic end block. Fig.10 As shown, by arranging multiple detection positions 4 in a circular array, the pressure detection members 14 arranged at each position of the circular array can independently detect the force exerted by the mixture on the telescopic end block at this position, and when setting the telescopic end block here, a rigid material can be selected to set the telescopic end block, so the telescopic end block set at this time does not need to be elastically deformed. Moreover, for the mixture, different telescopic end blocks can be squeezed at multiple positions respectively, thereby ensuring that the telescopic end block can independently realize the transmission of the force, thereby realizing the detection of the viscosity of the mixture in multiple position directions.

[0059] It should be noted that, for the annular end block and the telescopic end block, there is no need for them to have a large position change in the detection position 4 when setting them up, because the purpose of the sliding end block 15 is only to transmit the force of the mixture. Therefore, there is no need to prepare a large travel distance for the annular end block and the telescopic end block in the detection position 4, so as to avoid the mixture from entering the detection position 4 from the gap between the detection position 4 and the sliding end block 15, and avoid affecting the normal detection of the pressure detection part 14.

[0060] As for the setting method of the above-mentioned sliding end block 15, when setting, it includes the following structural settings: the detection position 4 is an end block slide 16, the pressure detection component 14 is fixedly set inside the end block slide 16, and the pressure detection component 14 is connected to the PLC integrated mainboard; different from the different setting methods of the above-mentioned sliding end block 15, the setting method of the sliding end block 15 here is also different. For the annular end block, the annular end block slide 16 is set in conjunction with the annular end block to meet the setting requirements of the annular end block; and for the telescopic end block, the telescopic end block slide 16 needs to be set in conjunction with the telescopic end block, so that the detection position 4 can meet the setting requirements of different sliding end blocks 15, and its purpose is to ensure that the sliding end block 15 can effectively cooperate with the detection position 4, so that the pressure detection component 14 inside the detection position 4 can effectively perform pressure value detection.

[0061] As for the setting method of the sliding end block 15, the main thing is that the end surface of the sliding end block 15 in contact with the mixed material cannot hinder the normal passage of the mixed material, so as to avoid the problem of mixed material clogging in the extrusion channel. Therefore, it is necessary to set the outer end surface of the sliding end block 15, the sliding end block 15 is set inside the end block slide groove 16, and the outer end surface of the sliding end block 15 is an outward convex arc surface structure. Fig. 9 As shown, firstly, it should not cause blockage to the normal passage of the mixture in the extrusion channel, and secondly, it is also necessary to ensure that the mixture can effectively exert a force on the sliding end block 15. Therefore, the outer end face of the sliding end block 15 is set to an outward convex arc surface structure, so that while the mixture can effectively exert a force on the sliding end block 15, the normal passage of the mixture in the extrusion channel will not be hindered due to the setting of the sliding end block 15, thereby avoiding the problem of blockage of the mixture in the extrusion channel and affecting the normal preparation of the defoaming masterbatch.

[0062] For the docking collar 3 set in the second use environment, its inner end position can be set using the channel detection structure component 6, because it is connected to the extrusion channel of the mixed material that completes the heating operation, so there is no need to worry about the viscosity of the mixed material at this time.

[0063] The detection method of the defoaming masterbatch raw material production detection equipment based on the fluid viscosity principle includes the following steps:

[0064] S1, docking a detection collar equipped with different detection components 2 with different positions inside the extrusion channel to detect the fluid viscosity of the mixture;

[0065] S2, the detection rings of the detection positions 4 on both sides are installed with the channel detection structure components 6 and are connected to the inside of the extrusion channel. When the mixed material in the extrusion channel passes through the channel detection structure component 6, the mixed material contacts the soft outer ring sleeve 10 of the center ring 7, so that the mixed material drives the soft outer ring sleeve 10 to move, and drives the docking rotor 8 to rotate, so that the angle sensor component 9 detects the rotation data of the docking rotor 8, and transmits the data to the PLC integrated mainboard for digital-to-analog conversion, and obtains the specific data of the rotation of the docking rotor 8 at this time, so that the PLC integrated mainboard obtains the rotation angle change of the docking rotor 8 in real time; at this time, the soft outer ring sleeve 10 transmits the force to the central double helical shaft 11, so that the central double helical shaft 11 is rotated in the semicircular slideway reinforcement rib 12, and provides conditions for the rotation of the soft outer ring sleeve 10;

[0066] S3, the detection collars of the detection positions 4 on both sides, which are respectively equipped with the channel detection structure component 6 and the port detection structure component 5, are connected to the inside of the extrusion channel, so that the detection collar close to the port detection structure component 5 is connected to the outlet end position of the extrusion channel; when the mixed material inside the extrusion channel passes through the channel detection structure component 6, the mixed material contacts the soft outer ring sleeve 10 of the center ring 7, so that the mixed material drives the soft outer ring sleeve 10 to move, and drives the docking rotor 8 to rotate, so that the angle sensing component 9 detects the rotation data of the docking rotor 8, and transmits the data to the PLC integrated mainboard for digital-to-analog conversion, and obtains the specific data of the rotation of the docking rotor 8 at this time, so that the PLC integrated mainboard obtains the rotation angle change of the docking rotor 8 in real time; at this time, the soft outer ring sleeve 10 transmits the force to the central double helical shaft 11, so that the central double helical shaft 11 is rotated in the semicircular slideway reinforcement rib 12, and provides conditions for the rotation of the soft outer ring sleeve 10;

[0067] When the mixed material inside the extrusion channel passes through the port detection structure component 5, the mixed material contacts the inner end surface of the sliding end block 15, so that the mixed material generates a force on the inner end surface of the sliding end block 15, and transmits the force to the pressure detection component 14. The pressure detection component 14 transmits the detection data to the PLC integrated mainboard, so that the PLC integrated mainboard performs digital-to-analog conversion on the detection data of the pressure detection component 14, so that the PLC can continuously obtain the pressure value change of the sliding end block 15 on the pressure detection component 14;

[0068] S4, analyzes and monitors the implementation data obtained by the PLC integrated mainboard. When the data expressed by the PLC integrated mainboard changes abnormally, the staff analyzes the components that transmit the abnormal information to the PLC integrated mainboard, and then solves the factors that affect the viscosity change of the mixture.

[0069] Therefore, the production and testing equipment of defoaming masterbatch raw materials based on the principle of fluid viscosity can avoid the problem of mixing the mixed materials, which causes the extruded material in the defoaming masterbatch to contain more water, thereby avoiding the problem of bubbles appearing inside the defoaming masterbatch after the subsequent drying of the defoaming masterbatch, thereby ensuring that the company has good production benefits and avoiding large production losses.
