Description

Technical Field

[0001] The present invention relates to the technical field of masterbatch ingredient mixing devices, and specifically to a masterbatch ingredient mixing device with a water content detection function. Background Art

[0002] In the plastic processing process, masterbatch ingredients are important raw materials, and the quality after mixing directly affects the performance of the final product. The water content of masterbatch ingredients is one of the important indicators for judging whether their quality meets the production requirements. The existing masterbatch ingredient mixing devices on the market only mix the masterbatch ingredients and then manually take samples for water content detection. The operation process is cumbersome and the production time is prolonged. Therefore, we need a masterbatch ingredient mixing device with a water content detection function to automatically take samples and detect the water content of masterbatch ingredients during the mixing process, realize the automation of the water content of masterbatch ingredients, accelerate the production process, and improve production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a masterbatch ingredient mixing device with a water content detection function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The mixing device includes a main material bin, an auxiliary material bin, a mixing pipe, a premixing module, a stirring module, a connecting pipe, and a detection module. The discharge port of the main material bin is fixedly connected to an inlet of the mixing pipe, the discharge port of the auxiliary material bin is fixedly connected to an inlet of the mixing pipe, the discharge port of the mixing pipe is inserted into the upper end surface of one end of the premixing module, the other end of the premixing module is inserted into the upper part of the stirring module, the premixing module and the stirring module are fixedly connected, one end of the connecting pipe is inserted into the bottom end of the premixing module, the connecting pipe and the premixing module are fixedly connected, the other end of the connecting pipe is inserted into the upper end of the detection module, the connecting pipe and the detection module are fixedly connected, and the connecting pipe is located between the mixing pipe and the stirring module.

[0006] The masterbatch ingredients flow into the mixing pipe from the main ingredient bin and the auxiliary ingredient bin respectively. After being mixed by the mixing pipe, the masterbatch ingredients enter the premixing module. The premixing module transports the mixed masterbatch ingredients to the stirring module for stirring. During the transportation process, the premixing module conducts preliminary stirring and mixing on the mixed masterbatch ingredients, accelerating the process of the masterbatch ingredients reaching the predetermined mixing standard, improving production efficiency. The masterbatch ingredients that reach the predetermined mixing standard after stirring in the stirring module flow out from the discharge port of the stirring module. During the transportation process of the premixing module, the connecting pipe is intermittently opened, enabling the premixing module and the detection module to be connected. The connecting pipe puts the quantitatively preliminarily mixed masterbatch ingredients into the detection module. The detection module detects the water content of the falling masterbatch ingredients. When the display result of the water content detection is within the set range, the mixing device operates normally; when the display result of the water content detection is not within the set range, the mixing device stops working, and the operator replaces the masterbatch ingredients. The masterbatch ingredients after being detected fall to the bottom of the detection module for collection and are regularly cleaned by the operator.

[0007] Further, the premixing module includes a premixing pipe, a conveying motor, and a conveying screw rod. The conveying motor is arranged at one end of the premixing pipe. The discharge port of the mixing pipe is inserted into the upper end surface of one end of the premixing pipe. The other end of the premixing pipe is inserted into the upper part of the stirring module. The discharge port of the mixing pipe is located between the conveying motor and the stirring module. One end of the connecting pipe is inserted into the lower end surface of the premixing pipe. The connecting pipe is located between the inlet of the mixing pipe and the stirring module. The conveying screw rod is arranged inside the premixing pipe, and the conveying screw rod is fixedly connected to the output end of the conveying motor.

[0008] The masterbatch ingredients mixed by the mixing pipe fall into one end of the premixing pipe close to the conveying motor. The conveying motor drives the conveying screw rod to rotate, which not only conveys the masterbatch ingredients towards the connecting pipe and the stirring module but also conducts preliminary stirring and mixing on the masterbatch ingredients, making the water content detection of the masterbatch ingredients entering the detection module through the connecting pipe more accurate. At the same time, it also plays a role in accelerating the process of the masterbatch ingredients reaching the predetermined mixing standard, improving production efficiency.

[0009] Further, the length of the conveying screw rod is greater than or equal to the length of the premixing pipe.

[0010] The conveying screw rod is responsible for conveying the masterbatch ingredients. When the length of the conveying screw rod is shorter than the length of the premixing pipe, it is not easy to convey the masterbatch ingredients to the stirring module, and it is easy to cause the situation that the masterbatch ingredients are blocked in the premixing pipe.

[0011] Further, the stirring module includes a stirring tank, a stirring motor, a lifting screw rod, a stirring column and stirring rods. The other end of the premixing pipe is inserted into the upper part of the stirring tank. The stirring motor is arranged at the bottom end of the stirring tank. The output shaft of the stirring motor is connected to the lifting screw rod. The central axis of the lifting screw rod coincides with the central axis of the stirring tank. The stirring column sleeves the lifting screw rod. The bottom end of the stirring column is fixedly connected to the lifting screw rod. The bottom end and the top end of the stirring column are both unobstructed. The stirring column is higher than the lower end face of the premixing pipe inserted into the stirring tank. The two ends of the lifting screw rod pass through the two ends of the stirring column. The central axis of the stirring column coincides with the central axis of the lifting screw rod. The stirring rods are arranged on the outer wall surface of the stirring column. The stirring rods are lower than the lower end face of the premixing pipe inserted into the stirring tank.

[0012] The bottom part of the stirring tank is funnel-shaped. The masterbatch ingredients conveyed by the premixing module fall into the stirring tank. The top plane of the masterbatch ingredients stirred in the stirring tank is always lower than the lower end face of the premixing pipe, preventing the premixing module from being blocked and causing equipment failure. The stirring motor drives the stirring column to rotate. When the stirring column rotates, the stirring rods stir and mix the masterbatch ingredients. During the stirring process, some ingredients with overall dimensions smaller than those of the masterbatch will gather in large quantities at the lower part of the stirring tank. The lifting screw rod vertically conveys the masterbatch ingredients gathered at the lower part of the stirring tank upward, and then gushes out from the upper end of the stirring column and falls onto the upper end face of the masterbatch ingredients for stirring, making the masterbatch ingredients more evenly stirred and mixed. At the same time, the upper end face of the stirring column is higher than the lower end face of the premixing pipe inserted into the stirring tank, preventing the lifting screw rod from being blocked during lifting and conveying and causing equipment failure. The masterbatch ingredients after stirring flow out from the discharge port of the stirring tank.

[0013] Further, a discharge pipe is arranged at the lower end face of the stirring tank.

[0014] Setting the discharge pipe facilitates the collection and treatment of the masterbatch ingredients after stirring.

[0015] Further, a first electronic valve is arranged on the connecting pipe.

[0016] Through the timed opening and closing of the first electronic valve, the masterbatch ingredients in the premixing pipe enter the detection module intermittently and quantitatively for moisture content detection.

[0017] Furthermore, the detection module includes a housing, a fixing base, a weighing scale, a driving motor, a heating chamber, a soft brush, and a storage bin. The housing is disposed below the premixing pipe. A fixing pipe is provided on the inner wall surface at the upper end of the housing. The connecting pipe is inserted into the fixing pipe. The heating chamber is provided on the inner wall surface at the upper end of the housing. The fixing base is disposed inside the housing. Both sides of the fixing base are fixedly connected to the housing. The weighing scale is slidably connected to the fixing base. The weighing scale slides around the outer circle of the fixing base. When the weighing scale slides to directly below the heating chamber, a closed space is formed with the heating chamber. The fixing pipe is disposed on the sliding path of the weighing scale. An axial symmetry plane of the fixing pipe coincides with an axial symmetry plane of the heating chamber. The driving motor drives the weighing scale to slide. The soft brush is provided on a side wall surface inside the housing near the fixing pipe. The soft brush is fixedly connected to the housing. The horizontal axial symmetry plane of the soft brush coincides with the horizontal axial symmetry plane of the fixing base. The soft hair end of the soft brush faces the fixing base. The storage bin is located below the fixing base. The storage bin is slidably connected to the housing.

[0018] The initial position of the weighing scale is directly below the fixing pipe. The masterbatch ingredients in the premixing pipe sequentially fall into the weighing scale through the connecting pipe and the fixing pipe. The weighing scale weighs the masterbatch ingredients once. When the weighing value is stable, the driving motor starts. The weighing scale slides to directly below the heating chamber and forms a closed space with the heating chamber to heat the masterbatch ingredients on the weighing scale and evaporate the moisture therein. The weighing scale weighs the dried masterbatch ingredients a second time. When the value is stable, the driving motor starts. The weighing scale slides around the fixing base along the previous sliding direction towards the soft brush. During the sliding towards the soft brush, the masterbatch ingredients in the weighing scale fall into the storage bin. The weighing scale passes through the soft brush and returns to directly below the fixing pipe, waiting for the next detection. When the weighing scale passes through the soft brush, the soft hair end of the soft brush sweeps across the weighing scale to clean the possible residual masterbatch ingredients on the weighing scale, preventing the influence on the accuracy of the next moisture content detection.

[0019] Furthermore, a control display is provided on the housing. The control display is electrically connected to the weighing scale, the heating chamber, the first electronic valve, and the driving motor.

[0020] The control display can control the rotation speed of the driving motor, thereby controlling the traveling speed of the weighing scale on the fixing base; the control display can control the heating temperature in the heating chamber and adjust the temperature according to actual needs; the control display can set the opening and closing of the first electronic valve to control the amount and interval time of the masterbatch ingredients falling into the detection module through the connecting pipe; the control display can display the weight of the masterbatch ingredients weighed by the weighing scale before entering the heating chamber and the weight of the masterbatch ingredients after heating in the heating chamber, and simultaneously calculate and display the moisture content of the masterbatch ingredients.

[0021] Further, an air outlet pipe is provided on the outer shell. The air outlet pipe is inserted between the outer shell and the heating chamber. A second electronic valve is provided on the air outlet pipe, and the second electronic valve is electrically connected to the control display.

[0022] When the heating chamber is heating, the second electronic valve is in a closed state. The water vapor generated by the heating of the heating chamber enters the air outlet pipe. When the heating of the heating chamber is completed, the second electronic valve opens to discharge the water vapor in the air outlet pipe, and then the second electronic valve closes again after the discharge.

[0023] Further, heating rods are provided on the inner wall of the heating chamber, and the heating rods are electrically connected to the control display.

[0024] The control display controls the temperature in the heating chamber by controlling the heating rods, so as to set the temperature in the heating chamber according to actual needs.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The present invention is provided with a premixing module. The masterbatch ingredients are preliminarily stirred and mixed in the premixing module, accelerating the process of the masterbatch ingredients reaching the predetermined mixing standard and improving production efficiency.

[0027] 2. The present invention is provided with a lifting screw rod and a stirring column in the stirring module, which vertically conveys the masterbatch ingredients gathered at the lower part of the stirring tank upward, and then gushes out from the upper end of the stirring column and falls onto the upper surface of the masterbatch ingredients for stirring, making the stirring and mixing of the masterbatch ingredients more uniform.

[0028] 3. The detection module of the present invention can automatically sample and detect the water content of the masterbatch ingredients transported from the premixing module to the stirring module, realizing the automation of the water content detection of the masterbatch ingredients without manual sampling and measurement.

Specific embodiments

[0035] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment: As Figure 1 - Figure 5 shown, the present invention provides a technical solution for a masterbatch batching and mixing device with a water content detection function:

[0037] As Figure 1 shown, the mixing device includes a main material bin 1, an auxiliary material bin 2, a mixing pipe 3, a premixing module 4, a stirring module 5, a connecting pipe 6 and a detection module 7. The discharge port of the main material bin 1 is fixedly connected to an inlet of the mixing pipe 3, the discharge port of the auxiliary material bin 2 is fixedly connected to an inlet of the mixing pipe 3, the discharge port of the mixing pipe 3 is inserted into the upper end surface of one end of the premixing module 4, the other end of the premixing module 4 is inserted into the upper part of the stirring module 5, the premixing module 4 and the stirring module 5 are fixedly connected, one end of the connecting pipe 6 is inserted into the bottom end of the premixing module 4, the connecting pipe 6 and the premixing module 4 are fixedly connected, the other end of the connecting pipe 6 is inserted into the upper end of the detection module 7, the connecting pipe 6 and the detection module 7 are fixedly connected, and the connecting pipe 6 is located between the mixing pipe 3 and the stirring module 5.

[0038] The masterbatch ingredients flow into the mixing pipe 3 from the main material bin 1 and the auxiliary material bin 2 respectively. After being mixed by the mixing pipe 3, the masterbatch ingredients enter the premixing module 4. The premixing module 4 transports the mixed masterbatch ingredients to the stirring module 5 for stirring. During the transportation process, the premixing module 4 conducts preliminary stirring and mixing on the mixed masterbatch ingredients, accelerating the process of the masterbatch ingredients reaching the predetermined mixing standard, improving production efficiency. The masterbatch ingredients that reach the predetermined mixing standard after stirring in the stirring module 5 flow out from the discharge port of the stirring module 5. During the transportation process of the premixing module 4, the connecting pipe 6 is intermittently opened, enabling the premixing module 4 to communicate with the detection module 7. The connecting pipe 6 puts the quantitatively preliminarily mixed masterbatch ingredients into the detection module 7. The detection module 7 detects the water content of the falling masterbatch ingredients. When the display result of the water content detection is within the set range, the mixing device operates normally; when the display result of the water content detection is not within the set range, the mixing device stops working, and the operator replaces the masterbatch ingredients. The masterbatch ingredients after detection fall to the bottom of the detection module 7 for collection and are regularly cleaned by the operator.

[0039] As Figure 2 and Figure 3 shown, the premixing module 4 includes a premixing pipe 41, a conveying motor 42, and a conveying screw rod 43. The conveying motor 42 is arranged at one end of the premixing pipe 41. The discharge port of the mixing pipe 3 is inserted into the upper end surface of one end of the premixing pipe 41. The other end of the premixing pipe 41 is inserted into the upper part of the stirring module 5. The discharge port of the mixing pipe 3 is located between the conveying motor 42 and the stirring module 5. One end of the connecting pipe 6 is inserted into the lower end surface of the premixing pipe 41. The connecting pipe 6 is located between the inlet of the mixing pipe 3 and the stirring module 5. The conveying screw rod 43 is arranged inside the premixing pipe 41, and the conveying screw rod 43 is fixedly connected to the output end of the conveying motor 42.

[0040] The masterbatch ingredients mixed by the mixing pipe 3 fall into one end of the premixing pipe 41 close to the conveying motor 42. The conveying motor 42 drives the conveying screw rod 43 to rotate, while transporting the masterbatch ingredients towards the connecting pipe 6 and the stirring module 5, conducting preliminary stirring and mixing on the masterbatch ingredients, making the water content detection of the masterbatch ingredients entering the detection module 7 through the connecting pipe 6 more accurate, and at the same time also playing a role in accelerating the process of the masterbatch ingredients reaching the predetermined mixing standard, improving production efficiency.

[0041] As Figure 2 and Figure 3 shown, the length of the conveying screw rod 43 is greater than or equal to the length of the premixing pipe 41.

[0042] The conveying screw rod 43 is responsible for conveying the masterbatch ingredients. When the length of the conveying screw rod 43 is shorter than that of the premixing pipeline 41, it is not easy to convey the masterbatch ingredients to the stirring module 5, and it is easy to cause the masterbatch ingredients to block in the premixing pipeline 41.

[0043] As Figure 2 and Figure 4 shown, the stirring module 5 includes a stirring tank 51, a stirring motor 52, a lifting screw rod 53, a stirring column 54 and stirring rods 55. The other end of the premixing pipeline 41 is inserted into the upper part of the stirring tank 51. The stirring motor 52 is arranged at the bottom end of the stirring tank 51. The output shaft of the stirring motor 52 is connected to the lifting screw rod 53. The central axis of the lifting screw rod 53 coincides with the central axis of the stirring tank 51. The stirring column 54 sleeves the lifting screw rod 53. The bottom end of the stirring column 54 is fixedly connected to the lifting screw rod 53. The bottom end and the top end of the stirring column 54 are both unobstructed. The stirring column 54 is higher than the lower end face of the premixing pipeline 41 inserted into the stirring tank 51. The two ends of the lifting screw rod 53 pass through the two ends of the stirring column 54. The central axis of the stirring column 54 coincides with the central axis of the lifting screw rod 53. The stirring rods 55 are arranged on the outer wall surface of the stirring column 54. The stirring rods 55 are lower than the lower end face of the premixing pipeline 41 inserted into the stirring tank 51.

[0044] The bottom part of the stirring tank 51 is funnel-shaped. The masterbatch ingredients conveyed by the premixing module 4 fall into the stirring tank 51. The top plane of the masterbatch ingredients stirred in the stirring tank 51 is always lower than the lower end face of the premixing pipeline 41, preventing the premixing module 4 from being blocked and causing equipment failure. The stirring motor 52 drives the stirring column 54 to rotate. When the stirring column 54 rotates, the stirring rods 55 stir and mix the masterbatch ingredients. During the stirring process, some ingredients will gather in the lower part of the stirring tank 51 because their overall size is smaller than that of the masterbatch. The lifting screw rod 53 vertically conveys the masterbatch ingredients gathered in the lower part of the stirring tank 51 upward, and then gushes out from the upper end of the stirring column 54 and falls onto the upper end face of the masterbatch ingredients for stirring, making the masterbatch ingredients stirred and mixed more evenly. At the same time, the upper end face of the stirring column 54 is higher than the lower end face of the premixing pipeline 41 inserted into the stirring tank 51, preventing the lifting screw rod 53 from being blocked during the lifting and conveying process and causing equipment failure. The masterbatch ingredients after stirring flow out from the discharge port of the stirring tank 51.

[0045] As Figure 1 shown, a discharge pipe 56 is arranged on the lower end face of the stirring tank 51.

[0046] Setting the discharge pipe 56 facilitates the collection and treatment of the masterbatch ingredients after stirring.

[0047] As Figure 1 - Figure 3As shown, a first electronic valve 61 is provided on the connecting pipe 6.

[0048] Through the timed opening and closing of the first electronic valve 61, the masterbatch ingredients in the premixing pipeline 41 enter the detection module 7 intermittently and quantitatively for moisture content detection.

[0049] As Figure 2 and Figure 5 As shown, the detection module 7 includes a housing 71, a fixed seat 72, a weighing scale 73, a driving motor 74, a heating chamber 75, a soft brush 76 and a storage bin 77. The housing 71 is arranged below the premixing pipeline 41. On the upper inner wall surface of the housing 71, a fixed pipe 78 is provided. The connecting pipe 6 is inserted into the fixed pipe 78. The heating chamber 75 is arranged on the upper inner wall surface of the housing 71. The fixed seat 72 is arranged inside the housing 71. Both sides of the fixed seat 72 are fixedly connected to the housing 71. The weighing scale 73 is slidably connected to the fixed seat 72. The weighing scale 73 slides around the outer circle of the fixed seat 72. When the weighing scale 73 slides to directly below the heating chamber 75, a closed space is formed with the heating chamber 75. The fixed pipe 78 is arranged on the sliding path of the weighing scale 73. An axisymmetric plane of the fixed pipe 78 coincides with an axisymmetric plane of the heating chamber 75. The driving motor 74 drives the weighing scale 73 to slide. The soft brush 76 is arranged on a side wall surface inside the housing 71 close to the fixed pipe 78. The soft brush 76 is fixedly connected to the housing 71. The horizontal axisymmetric plane of the soft brush 76 coincides with the horizontal axisymmetric plane of the fixed seat 72. The soft hair end of the soft brush 76 faces the fixed seat 72. The storage bin 77 is located below the fixed seat 72. The storage bin 77 is slidably connected to the housing 71.

[0050] The initial position of the weighing scale 73 is directly below the fixed pipe 78. The masterbatch ingredients in the premixing pipeline 41 sequentially pass through the connecting pipe 6 and the fixed pipe 78 and fall into the weighing scale 73. The weighing scale 73 weighs the masterbatch ingredients once. Until the weighing value is stable, the driving motor 74 is started. The weighing scale 73 slides to directly below the heating chamber 75 to form a closed space with the heating chamber 75. The masterbatch ingredients on the weighing scale 73 are heated to evaporate the moisture therein. The weighing scale 73 weighs the dried masterbatch ingredients a second time. Until the value is stable, the driving motor 74 is started. The weighing scale 73 slides around the fixed seat 72 along the previous sliding direction towards the soft brush 76. During the sliding towards the soft brush 76, the masterbatch ingredients in the weighing scale 73 fall into the storage bin 77. The weighing scale 73 passes through the soft brush 76 and returns to directly below the fixed pipe 78, waiting for the next detection. When the weighing scale 73 passes through the soft brush 76, the soft hair end of the soft brush 76 sweeps across the weighing scale 73 to clean the possible remaining masterbatch ingredients on the weighing scale 73 to prevent affecting the accuracy of the next moisture content detection.

[0051] As Figure 1As shown, a control display 79 is provided on the outer shell 71. The control display 79 is electrically connected to the weighing scale 73, the control display 79 is electrically connected to the heating chamber 75, the control display 79 is electrically connected to the first electronic valve 61, and the control display 79 is electrically connected to the drive motor 74.

[0052] The control display 79 can control the rotation speed of the drive motor 74, thereby controlling the traveling speed of the weighing scale 73 on the fixed seat 72; the control display 79 can control the heating temperature in the heating chamber 75 and adjust the temperature according to actual needs; the control display 79 can set the opening and closing of the first electronic valve 61 to control the amount and interval time of the masterbatch ingredients falling into the detection module 7 through the connecting pipe 6; the control display 79 can display the weight of the masterbatch ingredients before entering the heating chamber 75 weighed by the weighing scale 73 and the weight of the masterbatch ingredients after being heated in the heating chamber 75, and at the same time calculate and display the moisture content of the masterbatch ingredients.

[0053] As Figure 2 and Figure 5 shown, an air outlet pipe 710 is provided on the outer shell 71. The air outlet pipe 710 is inserted into the outer shell 71 and the heating chamber 75. A second electronic valve 711 is provided on the air outlet pipe 710, and the second electronic valve 711 is electrically connected to the control display 79.

[0054] When the heating chamber 75 is heating, the second electronic valve 711 is in a closed state. The water vapor generated by the heating of the heating chamber 75 enters the air outlet pipe 710. When the heating of the heating chamber 75 is completed, the second electronic valve 711 is opened to discharge the water vapor in the air outlet pipe 710, and the second electronic valve 711 is closed again after the discharge.

[0055] As Figure 2 shown, heating rods 712 are provided on the inner wall of the heating chamber 75, and the heating rods 712 are electrically connected to the control display 79.

[0056] The control display 79 controls the temperature in the heating chamber 75 by controlling the heating rods 712, thereby setting the temperature in the heating chamber 75 according to actual requirements.

[0057] Working principle of the present invention: The masterbatch ingredients flow into the mixing pipe 3 from the main material bin 1 and the auxiliary material bin 2 respectively. After being mixed in the mixing pipe 3, the masterbatch ingredients enter the premixing module 4. The premixing module 4 conveys the mixed masterbatch ingredients to the stirring module 5 for stirring. During the conveying process, the premixing module 4 performs preliminary stirring and mixing on the mixed masterbatch ingredients, accelerating the process for the masterbatch ingredients to reach the predetermined mixing standard and improving the production efficiency. The masterbatch ingredients that reach the predetermined mixing standard after stirring in the stirring module 5 flow out from the discharge port of the stirring module 5. During the conveying process of the premixing module 4, the connecting pipe 6 is intermittently opened, enabling the premixing module 4 to communicate with the detection module 7. The connecting pipe 6 puts the quantitatively preliminarily mixed masterbatch ingredients into the detection module 7. The detection module 7 detects the water content of the falling masterbatch ingredients. When the display result of the water content detection is within the set range, the mixing device works normally; when the display result of the water content detection is not within the set range, the mixing device stops working, and the operator replaces the masterbatch ingredients. The masterbatch ingredients after being detected fall into the storage box 77 for collection and are regularly cleaned by the operator.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
