Technical Field

[0002] In the production of composite material compression molding, a certain amount of premix or prepreg is usually added to the metal mold to improve the quality and efficiency of the molded product. When preparing the premix or prepreg, a perfusion gun is generally used to mix the raw materials with large proportion differences in multiple components. After the perfusion gun completes the mixing of the raw materials, the mixed liquid is injected into the metal mold, and then the molding equipment completes the production of the molded product. However, the existing perfusion gun has only one feed port, and the raw materials with large proportion differences in multiple components directly enter the perfusion gun from the feed port for mixing, which easily leads to uneven mixing of the multiple component raw materials and unstable quality of the mixed liquid. It is difficult to achieve the requirement of full mixing, which reduces the quality and efficiency of the subsequent molded product. Summary of the Invention

DETAILED DESCRIPTION

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0043] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] Example 1:

[0045] The embodiment of the present invention provides a high pressure injection gun, such as Figure 1-4 As shown, it includes: a primary mixing device 1 and a secondary mixing device 2. A main oil cylinder 3 is fixedly arranged on one side of the input end of the secondary mixing device 2, and the primary mixing device 1 is fixedly arranged on both sides of the main oil cylinder 3. The primary mixing device 1 and the secondary mixing device 2 are respectively connected to the main oil cylinder 3, and the output end of the primary mixing device 1 is connected to the input end of the secondary mixing device 2. A hydraulic port 6 is provided on the side wall of the main oil cylinder 3, and the main oil cylinder 3 is connected to an external hydraulic pump through the hydraulic port 6.

[0046] The working principle and beneficial effects of the above technical solution are:

[0047] When the high-pressure perfusion gun performs a mixing operation, the hydraulic pump is turned on and the main oil cylinder 3 is in an open state. Raw materials A and B are respectively transported to the primary mixing device 1 by the high-pressure pump for mixing. The evenly mixed mixture (A+B) is transported to the secondary mixing device 2 and mixed with the raw material C transported to the secondary mixing device 2 by the high-pressure pump under a high-pressure state to achieve collision mixing of (A+B)+C materials. The evenly mixed mixture (A+B)+C is supplied to the next process through the output end of the secondary mixing device 2. When the high-pressure perfusion gun stops mixing, the hydraulic pump is turned off, the main oil cylinder 3 is in a closed state, and the primary mixing device 1 and the secondary mixing device 2 stop mixing.

[0048] The first-stage mixing device 1 and the second-stage mixing device 2 of the high-pressure perfusion gun can be expanded into a third-stage mixing device, a fourth-stage mixing device, or other multi-stage mixing devices, thereby achieving the mixing of more component raw materials;

[0049] The use of a high-pressure perfusion gun to complete the mixing of raw materials eliminates the process of converting containers. The mixing process is relatively simple, which makes the process of perfusion of raw materials from the beginning to the completion of mixing faster. At the same time, the use of a first-level mixing device 1 and a second-level mixing device 2 for graded collision mixing ensures the mixing quality and improves the speed and efficiency of raw material mixing.

[0050] Example 2

[0051] On the basis of the above embodiment 1, Figure 5-9 As shown, the primary mixing device 1 includes: a mixer 10 and a housing 11. The housing 11 is arranged on one side of the input end of the secondary mixing device 2. The outer side of the housing 11 is fixedly connected to the master cylinder 3. The mixer 10 is arranged inside the housing 11. The mixer 10 is arranged on the side of the housing 11 close to the secondary mixing device 2. The inner wall of the housing 11 is fixedly connected to the mixer 10.

[0052] A feed port 50 and a reflux port 61 are sequentially arranged on one side of the shell 11. A feed port 51 is arranged above the A feed port 50 and the B reflux port 61. The A feed port 50 and the B feed port 51 are respectively connected to the input end of the mixer 10. The side of the shell 11 close to the mixer 10 is connected to the input end of the secondary mixing device 2.

[0053] The working principle and beneficial effects of the above technical solution are:

[0054] When the high-pressure perfusion gun is performing a mixing operation, the B return port 61 is not connected to the interior of the housing 11. When the high-pressure perfusion gun is closed, the B return port 61 is connected to the B feed port 51 through the interior of the housing 11.

[0055] When the high-pressure perfusion gun performs the mixing operation, raw material A is transported to the mixer 10 through the A feed port 50 and raw material B is transported through the B feed port 51 by the high-pressure pump for mixing, and is uniformly mixed into a mixture (A+B) under high pressure. The mixture (A+B) is supplied to the secondary mixing device 2 through the output end of the mixer 10 for the next mixing step; the primary mixing device 1 first performs graded collision mixing on the raw materials A and B, ensuring the uniformity and quality of the mixing, providing convenience for subsequent mixing, accelerating the speed of subsequent mixing, and improving the efficiency of raw material mixing.

[0056] Example 3

[0057] On the basis of Example 1 or 2, as Figure 5-9 As shown, the primary mixing device 1 further includes: a small oil cylinder 4, which is arranged on one side of the input end of the mixer 10, one end of the small oil cylinder 4 is fixedly connected to the end of the housing 11 away from the secondary mixing device 2, the outer side of the small oil cylinder 4 is fixedly connected to the main oil cylinder 3, and the small oil cylinder 4 is connected to the main oil cylinder 3 through an oil passage 64;

[0058] The small oil cylinder 4 is provided with several positioning sleeves 41 at one end close to the mixer 10, and the positioning sleeves 41 are fixedly connected to the inner wall of the small oil cylinder 4. The small oil cylinder 4 is provided with a tail cover 42 at one end away from the mixer 10, and the tail cover 42 is fixedly connected to the small oil cylinder 4. A small piston shaft 43 is provided inside the small oil cylinder 4, and a small seal 44 is provided on the outside of the small piston shaft 43. The small seal 44 is fixedly connected to the small piston shaft 43, and the small seal 44 is slidingly connected to the inner wall of the small oil cylinder 4. One end of the small piston shaft 43 is provided to pass through the positioning sleeve 41 and be slidingly connected to the inner wall of the outer shell 11, and the other end of the small piston shaft 43 is provided to pass through the tail cover 42 and be slidingly connected to the tail cover 42. A B reflux channel is provided on the end of the small piston shaft 43 close to the mixer 10, and the B feed port 51 is communicated with the B reflux port 61 through the B reflux channel.

[0059] The working principle and beneficial effects of the above technical solution are:

[0060] The small oil cylinder 4 in the primary mixing device 1 is connected to the main oil cylinder 3 through the oil passage 64. The hydraulic pump can control the small oil cylinder 4 and the main oil cylinder 3 to open and close synchronously, that is, the primary mixing device and the secondary mixing device 2 work synchronously, which is convenient for the staff to control and operate the high-pressure perfusion gun and speed up the mixing efficiency.

[0061] When the high-pressure perfusion gun performs a mixing operation, the hydraulic pump is turned on, the main oil cylinder 3 and the small oil cylinder 4 are synchronously in an open state, and the raw materials A and B are transported to the mixer 10 by the high-pressure pump for mixing to form a mixture (A+B); when the high-pressure perfusion gun stops the mixing operation, the hydraulic pump is turned off, the main oil cylinder 3 and the small oil cylinder 4 are synchronously in a closed state, and the small piston shaft 43 moves along the small oil cylinder 4 toward the positioning sleeve 41. When one end of the small piston shaft 43 moves to the input end of the mixer 10, the raw material B cannot enter the mixer 10. At the same time, the B reflux channel on the small piston shaft 43 connects the B feed port 51 with the B reflux port 61, and the raw material B can flow back to the feeding device to avoid waste. The small seal 44 is arranged on the outside of the small piston shaft 43 to prevent leakage of the raw material.

[0062] By setting the B reflux port 61, mixing can be stopped without turning off the high-pressure pump. When the mixing needs to be stopped frequently and temporarily, the frequent opening and closing of the high-pressure pump is avoided, and the mixing efficiency is accelerated. At the same time, when the high-pressure perfusion gun is closed, the main piston shaft pushes all the remaining materials in the gun head chamber out of the gun to achieve an automatic cleaning effect.

[0063] Example 4

[0064] On the basis of any one of Examples 1-3, Figure 5-9 As shown, the secondary mixing device 2 includes: a gun head 20, a gun head chamber 21 is arranged in the gun head 20, the gun head chamber 21 is connected to the main oil cylinder 3, a mixing feed port 52 is arranged on the end of the gun head 20 close to the mixer 10, and the mixing feed port 52 connects the gun head chamber 21 with the side of the shell 11 close to the mixer 10, a return port A 60 is arranged on the side of the gun head 20 close to the mixer 10, a feed port C 53 is arranged on the end of the gun head 20 away from the mixer 10, a return port C 63 is arranged on the side of the gun head 20 close to the feed port C 53, a number of mounting ports 22 are arranged on both sides of the gun head 20, and a number of feeding ports 54 are arranged on the side of the gun head 20 close to the mounting port 22.

[0065] The working principle and beneficial effects of the above technical solution are:

[0066] When the high-pressure perfusion gun performs a mixing operation, the mixture (A+B) is transported through the mixing feed port 52 and the raw material C is transported through the C feed port 53 by the high-pressure pump to the gun head chamber 21 for mixing. Under high pressure, the mixture (A+B+C) is uniformly mixed. The mixture (A+B+C) is supplied to the next process through the output end of the gun head 20; the secondary mixing device 2 performs collision mixing on the mixture (A+B) and the raw material C, thereby ensuring the uniformity and quality of the mixing of the multiple components, accelerating the mixing speed, and improving the efficiency of the raw material mixing;

[0067] The setting of the feeding port 54 is conducive to adding small proportions of raw materials, ensuring the uniformity and quality of mixing of multiple components, accelerating the mixing speed, and improving the efficiency of raw material mixing. A pressure regulator is installed on the installation port 22. The function of the pressure regulator is to adjust the feed pressure of the high-pressure pump connected to the mixing feed port 52 and the C feed port 53, thereby adjusting the flow rate of the raw materials, which is conducive to the adjustment of the raw material ratio and improves the quality of raw material mixing.

[0068] Example 5

[0069] On the basis of any one of Examples 1-4, Figure 5-9 As shown, one side of the master cylinder 3 is fixedly connected to the gun head 20, the master cylinder 3 is communicated with the gun head chamber 21, a guide sleeve 31 is provided in the master cylinder 3 near the gun head 20, the guide sleeve 31 is fixedly connected to the inner wall of the master cylinder 3, a rear cover 32 is provided on the side of the master cylinder 3 away from the gun head 20, the rear cover 32 is fixedly connected to the master cylinder 3, a main piston shaft 33 is provided between the guide sleeve 31 and the rear cover 32, the main piston shaft 33 is connected to the main The inner wall of the oil cylinder 3 is slidably connected, and one end of the main piston shaft 33 passes through the guide sleeve 31 and is slidably connected to the gun head chamber 21. The main piston shaft 33 is provided with an A reflux channel at one end close to the mixing feed port 52, and the A feed port 50 is connected to the A reflux port 60 through the mixer 10 and the A reflux channel. The main piston shaft 33 is provided with a C reflux channel at one end close to the C feed port 53, and the C feed port 53 is connected to the C reflux port 63 through the C reflux channel.

[0070] The working principle and beneficial effects of the above technical solution are:

[0071] When the high-pressure perfusion gun performs a mixing operation, the hydraulic pump is turned on, the main oil cylinder 3 is in an open state, the main piston shaft 33 is in the main oil cylinder 3, and the mixture (A+B) and the raw material C are transported to the gun head chamber 21 for mixing to form a mixture (A+B+C); when the high-pressure perfusion gun stops the mixing operation, the hydraulic pump is turned off, the main oil cylinder 3 is in a closed state, and the main piston shaft 33 moves in the main oil cylinder 3 along the guide member 34. When one end of the main piston shaft 33 moves to the gun head chamber 21, the mixture (A+B) and the raw material C cannot enter the gun head chamber 21, and the mixing stops. At the same time, the A reflux channel on the main piston shaft 33 connects the A feed port 50 through the mixer 10, the A reflux channel and the A reflux port 60, and the C reflux channel connects the C feed port 53 and the C reflux port 63. The raw materials A and C can flow back to the feeding device to avoid waste. The main seal 36 is arranged on the outside of the main piston shaft 33 to prevent the mixture (A+B) and the raw material C from leaking;

[0072] By setting the A reflux port 60 and the C reflux port 63, mixing can be stopped without shutting down the high-pressure pump. When the mixing needs to be stopped frequently and temporarily, the frequent opening and closing of the high-pressure pump is avoided, thereby speeding up the mixing efficiency.

[0078] On the basis of any one of Examples 1-6, Figure 10-15 As shown, an adjustment mechanism is provided at the A feed port 50 and the B feed port 51, and the adjustment mechanism includes: an adjustment groove 70, the adjustment groove 70 is provided on the side of the housing 11 away from the mixer 10, a plurality of baffles 71 are provided in the adjustment groove 70, the baffles 71 are arc-shaped, and the baffles 71 are distributed in a ring array about the center of the adjustment groove 70, a fixing column 72 is provided at one end of the baffle 71, and the baffle 71 is fixed to the side of the fixing column 72 close to the mixer 10. The other side of the fixed post 72 is rotatably connected to the inner wall of the adjustment slot 70. A movable post 73 is provided on the end of the baffle 71 away from the fixed post 72. The side of the baffle 71 away from the fixed post 72 is fixedly connected to the movable post 73. A turntable 74 is provided on the side of the baffle 71 close to the movable post 73. The turntable 74 is rotatably connected to the inner wall of the adjustment slot 70. A plurality of rotating holes 75 are provided at equal angles on the turntable 74. The movable post 73 is slidably connected to the inner wall of the rotating hole 75.

[0079] A gear 76 is provided on one side of the turntable 74, and the gear 76 is rotatably connected to the adjustment slot 70. A motor 77 is provided on the side of the gear 76 close to the turntable 74, and the motor 77 is fixedly connected to the housing 11. The output end of the motor 77 is fixedly connected to the gear 76. A tooth groove is provided on the side of the turntable 74 close to the gear 76, and the gear 76 is meshed with the tooth groove. The motor 77 is electrically connected to an external controller.

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] When the high-pressure perfusion gun needs to adjust the diameters of feed port A and feed port B 51 respectively for mixing operation, the staff controls motor 77 to start through the controller, and motor 77 drives gear 76 to rotate, and gear 76 drives turntable 74 to rotate counterclockwise. Driven by the rotation of turntable 74, movable column 73 guides baffle 71 to rotate counterclockwise around fixed column 72, and baffle 71 rotates as a whole toward the center of the feed port, thereby reducing the diameter of the feed port; when it is necessary to enlarge the diameter of the feed port, the staff controls motor 77 to start through the controller, and motor 77 drives gear 76 to rotate in the opposite direction, and gear 76 drives turntable 74 to rotate clockwise. Driven by the rotation of turntable 74, movable column 73 guides baffle 71 to rotate clockwise around fixed column 72, and baffle 71 rotates as a whole toward the direction away from the center of the feed port, thereby expanding the diameter of the feed port;

[0082] The output end of the motor 77 passes through the housing 11 and is fixedly connected to the gear 76. Under the premise of not affecting the normal operation of the motor 77, the raw material is prevented from flowing into the motor 77 and affecting the normal operation of the motor 77. The tooth groove on one side of the turntable 74 is smaller than the outer diameter of the turntable 74, which limits the rotation of the turntable 74 and prevents the gear 76 from driving the turntable 74 to rotate beyond the adjustment range.

[0083] By adjusting the diameters of the A feed port and the B feed port 51 through the adjustment mechanism, it is beneficial to adjust the flow rate of the raw materials flowing into the mixer 10, accurately control the mixing ratio of the raw materials, ensure the uniformity and quality of the mixing, and help improve the efficiency of the raw material mixing.

[0084] Example 8

[0085] On the basis of any one of Examples 1-7, Figure 16-19 As shown, the secondary mixing device 2 further includes: a pipeline 8, which is arranged on one side of the output end of the gun head 20, and the pipeline 8 is connected to the gun head chamber 21;

[0086] A quick release mechanism is provided between the output end of the gun head 20 of the pipe 8 and the gun head 20, and the quick release mechanism includes: a clip 81 and a nut 82. A plurality of clips 81 are provided, and the clips 81 are provided at equal angles on the side of the pipe 8 close to the gun head 20. One end of the clip 81 is fixedly connected to the pipe 8, and a hook 83 is fixedly provided on the other end of the clip 81. The hook 83 is fixedly connected to the clip 81. A hook groove 84 is provided on the side of the gun head 20 close to the clip 81. A slider 85 is suspended in the hook groove 84, and the slider 85 is slidably connected to the inner wall of the hook groove 84. The nut 82 is provided on the outside of the gun head 20, and the nut 82 is slidably connected to the outside of the gun head 20. The nut 82 is threadedly connected to the outer wall of the pipe 8, and the inner wall of the nut 82 contacts the outer wall of the clip 81.

[0087] A plurality of pressurizing grooves 86 are provided on one side of the hook groove 84 close to the pipe 8, the hook groove 84 is communicated with the pressurizing groove 86, a limit block 87 is provided in the pressurizing groove 86, the limit block 87 is fixedly connected to the inner wall of the pressurizing groove 86, a pressure rod 88 is provided in the pressurizing groove 86, the pressure rod 88 is slidably connected to the inner wall of the pressurizing groove 86 and the limit block 87 respectively, a pressure pad 89 is provided on the top of the pressure rod 88, the bottom of the pressure pad 89 is fixedly connected to the pressure rod 88, the side of the pressure pad 89 is slidably connected to the inner wall of the pressurizing groove 86, and the bottom of the pressure pad 89 contacts the top of the limit block 87;

[0088] A pressing groove 90 is provided on the side of the hook groove 84 close to the gun head 20, and the pressing groove 90 is communicated with the hook groove 84. A button 91 is provided on the pressing groove 90, and the side of the button 91 is slidingly connected to the inner wall of the pressing groove 90. A spring 92 is provided at the bottom of the button 91, and one end of the spring 92 is fixedly connected to the slider 85, and the other end of the spring 92 is fixedly connected to the bottom of the hook groove 84.

[0089] The working principle and beneficial effects of the above technical solution are:

[0090] When the primary mixing device 1 and the secondary mixing device 2 of the high-pressure perfusion gun are expanded into a three-stage mixing device, a four-stage mixing device or other multi-stage mixing devices, it is necessary to connect the output end of the gun head 20 to other mixing devices through the pipeline 8;

[0091] The clip 81 is a metal spring, and the hook groove 84, the pressurizing groove 86, and the pressing groove 90 are interconnected and can be sealed. A certain amount of gas is set in the hook groove 84 so that the slider 85 is suspended in the hook groove 84. When the pipe 8 moves toward the gun head 20, the clip 81 also moves toward the hook groove 84. Due to the setting of the limit block 87, when the hook 83 passes through the pressurizing groove 86, the pressure pad 89 will not move downward. When the hook 83 on the clip 81 contacts the hook groove 84, under the elastic force of the clip 81, the hook 83 moves toward the hook groove 84 so that the hook 83 and the hook groove 84 are fixedly connected to each other, and at the same time, the inner surface of the clip 81 is in contact with the outer surface of the gun head 20.

[0092] When the hook 83 moves into the hook groove 84, the hook 83 causes the slider 85 to move into the hook groove 84. Since the hook groove 84 is connected to the pressurized groove 86 and the pressing groove 90, when the slider 85 moves downward, the gas in the hook groove 84 enters the pressurized groove 86 and the pressing groove 90, and the button 91 in the pressing groove 90 moves toward the outside of the gun head 20. The top of the button 91 is higher than the surface of the gun head 20. The pressure rod 88 in the pressurized groove 86 drives the pressure pad 89 to move toward the clip 81, so that the pressure pad 89 is in close contact with the inner surface of the clip 81. Then the nut 82 is threadedly connected to the pipe 8, so that the button 91 moves into the pressing groove 90. Since the nut 82 The inner wall contacts the clip 81, and most of the gas in the pressing groove 90 passes through the hook groove 84 and then enters the pressurizing groove 86, so that the pressure pad 89 is in closer contact with the inner surface of the clip 81. By increasing the pressure between the clip 81 and the pressure pad 89 and increasing the friction coefficient between the pressure pad 89 and the clip 81, the clip 81 and the gun head 20 are more closely fitted. In addition, the connection between the hook 83 and the hook groove 84 and the threaded connection between the nut 82 and the pipe 8 make the connection between the pipe 8 and the gun head 20 more secure, reducing the shaking of the pipe 8 during the transportation process, improving the transportation stability, and improving the mixing process of the high-pressure perfusion gun and the mixing efficiency.

[0093] When the pipe 8 needs to be removed, the nut 82 is separated from the pipe 8, and the button 91 moves upward under the action of the spring 92. The button 91 is pressed downward again, and the gas in the pressing groove 90 enters the hook groove 84. The slider 85 drives the hook 83 to move along the hook groove 84 toward the outside of the gun head 20, separating the hook 83 from the hook groove 84. Then, the pipe 8 is separated from the gun head 20, and the pipe 8 is removed;

[0094] By setting up a quick-release mechanism, multiple mixing devices can be quickly connected to achieve the mixing of more components of raw materials. It is also possible to switch between different mixing devices to mix different raw materials, which is beneficial to ensure the uniformity and quality of the mixing of multiple components, speed up the mixing process, and improve the efficiency of raw material mixing.

[0095] Example 9

[0096] On the basis of any one of Examples 1-8, speed sensors are respectively provided at the A feed port 50 and the B feed port 51, and the speed sensors are electrically connected to the controller;

[0097] A prompter is provided on one side of the controller, and the prompter is electrically connected to the controller;

[0098] The controller controls the operation of the prompter based on the speed sensor, comprising the following steps:

[0099] Step 1: Calculate the flow rate u of the mixed fluid in the mixer 10 using formula (1):

[0100]

[0101] Wherein, u is the flow rate of the mixed fluid in the mixer 10, s1 is the cross-sectional area of the A feed port 50, v1 is the injection speed of material A, s2 is the cross-sectional area of the B feed port 51, v2 is the injection speed of material B, d is the inner diameter of the tube of the mixer 10, and π is taken as 3.14;

[0102] Step 2: Calculate the Reynolds coefficient Re of the mixed fluid in the mixer 10 using formula (2):

[0103]

[0104] Wherein, Re is the Reynolds coefficient of the mixed fluid in the mixer 10, d is the inner diameter of the tube of the mixer 10, ρ is the density of the mixed fluid in the mixer 10, u is the flow rate of the mixed fluid in the mixer 10, and μ is the viscosity of the mixed fluid in the mixer 10;

[0105] Step 3: Calculate the pressure drop P of the mixer 10 using formula (3):

[0106]

[0107] Wherein, P is the pressure drop of the mixer 10, d is the inner diameter of the tube of the mixer 10, ρ is the density of the mixed fluid in the mixer 10, u is the flow rate of the mixed fluid in the mixer 10, μ is the viscosity of the mixed fluid in the mixer 10, and l is the length of the mixer 10;

[0108] Step 4: The controller compares the calculated pressure drop of the mixer 10 with the set range. When the calculated pressure drop value is lower than or exceeds the set range (0.05-0.1MPa), the controller controls the prompter to work, prompting the operator to adjust the cross-sectional area of the A feed port 50, the cross-sectional area of the B feed port 51, the speed of adding material A, and the speed of adding material B so that the pressure drop value is within the set range.

[0109] The working principle and beneficial effects of the above technical solution are:

[0110] The controller compares the calculated pressure drop of the mixer 10 with the set interval. When the calculated pressure drop value is lower than the set interval, the controller controls the prompter to work, prompting the operator to increase the pressure drop value to within the set interval by increasing the cross-sectional area of the A feed port 50, the cross-sectional area of the B feed port 51, and speeding up the speed of adding material A and the speed of adding material B; when the calculated pressure drop value exceeds the set interval, the controller controls the prompter to work, prompting the operator to reduce the cross-sectional area of the A feed port 50, the cross-sectional area of the B feed port 51, and slowing down the speed of adding material A and the speed of adding material B, so that the pressure drop value falls back to within the set interval. By adjusting the pressure drop value to always be within the set interval, it is beneficial to improve the mixing effect of the mixer 10 and improve the mixing efficiency.
