Description

Technical Field

[0001] This utility model relates to the technical field of raw material quantitative dispensing equipment, specifically a raw material masterbatch quantitative dispensing device. Background Art

[0002] When packaging raw material masterbatches, quantitative dispensing equipment is often required. Utility model patent application CN201920170966.8 discloses a solid raw material quantitative dispensing machine that combines a material conveying unit and a material buffering unit, simplifying the overall structure. By controlling a second or third conveying motor to fix the number of rotations of the motor shaft in each operating cycle, the number of rotations of the first or second screw is also fixed, thus ensuring a constant stroke for the first or second screw to push the material, resulting in equal material output and achieving quantitative dispensing of solid raw materials. However, according to the disclosed technical solution, existing raw material quantitative dispensing equipment, on the one hand, cannot accurately guarantee the quantitative dispensing of raw material masterbatches, thus compromising the packaging quality; on the other hand, it cannot flexibly adjust the quantitative weight of the raw material masterbatches, making it unsuitable for dispensing raw material masterbatches of different weights.

[0003] Therefore, how to design a quantitative dispensing device for raw material masterbatch has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material masterbatch quantitative dispensing device to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for quantitative dispensing of raw material masterbatch.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material masterbatch quantitative dispensing device, comprising a material cylinder and support legs, a stirring assembly mounted on the material cylinder, the stirring assembly including a motor and a rotating rod, a dispensing assembly mounted at the bottom of the material cylinder, the dispensing assembly including a bottom box one and a bottom box two, a feeding assembly mounted on the material cylinder, the feeding assembly including a feeding valve one and a feeding valve two, a loading assembly mounted inside the dispensing assembly, the loading assembly including an inner box and a spring, a discharge assembly mounted on the inner box, the discharge assembly including a discharge pipe and a solenoid valve, and a quantitative assembly mounted at the bottom of the inner box, the quantitative assembly including a button and a lead screw.

[0006] Furthermore, the support leg is welded to the bottom of the cylinder, the motor is bolted to the top of the cylinder, the bottom end of the rotating rod is clamped to the inner wall of the bottom of the cylinder, and the top end of the rotating rod passes through the top of the cylinder through a bearing and is keyed to the output shaft of the motor.

[0007] Furthermore, the bottom box one and the bottom box two are respectively installed on both sides of the bottom of the material cylinder by bolts. The bottom box one is connected to the inside of the material cylinder by the discharge valve one, and the bottom box two is connected to the inside of the material cylinder by the discharge valve two.

[0008] Furthermore, the inner box is installed inside the bottom box one and the bottom box two respectively. The bottom of the inner box is connected to the inner wall of the bottom of the bottom box one or the bottom box two respectively by springs. The outlet pipe is welded to the bottom of the inner box. The bottom end of the outlet pipe extends to the bottom of the bottom box one or the bottom box two respectively. The solenoid valve is installed at the bottom end of the outlet pipe.

[0009] Furthermore, the buttons are respectively installed inside the first and second bottom boxes, with the buttons located at the bottom of the inner box, and the lead screw has a scale mark.

[0010] Furthermore, the top end of the lead screw is mounted on the bottom of the button via a bearing, and the bottom end of the lead screw passes through the inner wall of the first or second base box via a thread and extends to the bottom of the first or second base box.

[0011] Furthermore, a pulley is welded to the bottom end of the lead screw, and a belt is installed on the pulley, with the belt sleeved on the outer side of the two pulleys.

[0012] Furthermore, a bidirectional gate is bolted to the outer side of the material cylinder, and switch assemblies are installed on the outer sides of both the first and second bottom boxes. The switch assemblies are connected to the motor and the bidirectional gate via wires. The bidirectional gate is connected to the button and the solenoid valve via wires. The button is connected to the first and second discharge valves via wires.

[0013] Beneficial effects: 1. When using this raw material masterbatch quantitative dispensing device, the raw material masterbatch is poured into the inner side of the hopper. The motor is turned on and stirred by the rotating rod to increase the feeding speed of the raw material masterbatch. The bidirectional gate is pushed to the top to open the first feeding valve, allowing the raw material masterbatch to fall into the inner box of the bottom box. As the weight of the raw material masterbatch increases, the inner box compresses the spring until the inner box squeeze button is pressed, at which point the first feeding valve stops working. Then, the bidirectional gate is pulled down to open the second feeding valve, allowing the raw material masterbatch to fall into the inner box of the second bottom box. At the same time, the solenoid valve at the bottom of the inner box of the bottom box is opened, allowing the raw material masterbatch to be discharged downward through the outlet pipe. The above operation is repeated until the raw material masterbatch is completely dispensed. This device can effectively and accurately control the weight of the raw material masterbatch, avoiding uneven dispensing. It also prevents the feeding valve at the top of the inner box and the solenoid valve at the bottom from opening simultaneously, ensuring the accuracy of the raw material masterbatch dispensing.

[0014] 2. When the required weight of the raw material masterbatch to be dispensed changes during use, rotating one lead screw causes the pulley on the lead screw to drive another pulley via a belt, which in turn drives the other lead screw to rotate synchronously. The lead screw causes the button to rise or fall synchronously inside the first and second bottom boxes, thereby adjusting the distance between the button and the inner box, and thus adjusting the weight control of the raw material masterbatch in the inner box. This not only improves the efficiency of weight control operation of the dispensed raw material masterbatch, but also avoids inconsistencies in the adjustment of the two buttons, ensuring the consistency of the weight of the raw material masterbatch dispensed in the two inner boxes.

[0015] 3. The raw material masterbatch quantitative dispensing device is reasonably designed, highly efficient and convenient to use, and suitable for quantitative dispensing of raw material masterbatch. Attached Figure Description

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 3This utility model provides a technical solution: a raw material masterbatch quantitative dispensing device, including a material cylinder 1 and support legs 2. A stirring assembly is installed on the material cylinder 1, the stirring assembly including a motor 3 and a rotating rod 4. A dispensing assembly is installed at the bottom of the material cylinder 1, the dispensing assembly including a first bottom box 5 and a second bottom box 6. A feeding assembly is installed on the material cylinder 1, the feeding assembly including a first feeding valve 7 and a second feeding valve 8. A loading assembly is installed inside the dispensing assembly, the loading assembly including an inner box 9 and a spring 10. The inner box 9... A discharge assembly is installed, comprising a discharge pipe 11 and a solenoid valve 12. A metering assembly is installed at the bottom of the inner box 9, comprising a button 13 and a lead screw 14. The button 13 is installed inside the first bottom box 5 and the second bottom box 6, respectively, and is located at the bottom of the inner box 9. The lead screw 14 has a scale mark, and its top end is mounted on the bottom of the button 13 via a bearing. The bottom end of the lead screw 14 passes through the inner wall of the first bottom box 5 or the second bottom box 6 via a thread and extends to the second bottom box 5 or the second bottom box 6. At the bottom of component 6, a pulley 15 is welded to the bottom end of the lead screw 14, and a belt 16 is mounted on the pulley 15. The belt 16 is sleeved on the outer side of the two pulleys 15. The support leg 2 is welded to the bottom of the material cylinder 1. The motor 3 is bolted to the top of the material cylinder 1. The bottom end of the rotating rod 4 is clamped to the inner wall of the bottom of the material cylinder 1, and the top end of the rotating rod 4 passes through the top of the material cylinder 1 through a bearing and is keyed to the output shaft of the motor 3. When the weight of the raw material masterbatch to be packaged changes, the lead screw 14 is rotated. The pulley 15 on the lead screw 14 drives another pulley 15 via the belt 16, which in turn drives the other lead screw 14 to rotate synchronously. The lead screw 14 drives the button 13 to rise or fall synchronously inside the bottom box 5 and the bottom box 6, thereby adjusting the distance between the button 13 and the inner box 9, and thus adjusting the weight control of the raw material masterbatch in the inner box 9. This can improve the efficiency of weight control operation of the packaged raw material masterbatch, and also avoid inconsistencies in the adjustment of the two buttons 13, ensuring the consistency of the weight of the raw material masterbatch packaged in the two inner boxes 9.

[0022] In this embodiment, the first bottom box 5 and the second bottom box 6 are respectively bolted to the two sides of the bottom of the material cylinder 1. The first bottom box 5 is connected to the inner side of the material cylinder 1 through the first discharge valve 7, and the second bottom box 6 is connected to the inner side of the material cylinder 1 through the second discharge valve 8. The inner box 9 is respectively installed inside the first bottom box 5 and the second bottom box 6. The bottom of the inner box 9 is connected to the inner wall of the bottom of the first bottom box 5 or the second bottom box 6 through the spring 10. The outlet pipe 11 is welded to the bottom of the inner box 9. The bottom end of the outlet pipe 11 extends to the bottom of either bottom box 5 or bottom box 6. The solenoid valve 12 is installed at the bottom end of the outlet pipe 11. A bidirectional gate 17 is bolted to the outer side of the material cylinder 1. Switch assemblies 18 are installed on the outer sides of both bottom boxes 5 and 6. The switch assemblies 18 are connected to the motor 3 and the bidirectional gate 17 via wires. The bidirectional gate 17 is connected to the button 13 and the solenoid valve 12 via wires. The button 13 is connected to the discharge valve 7 via wires. Connected to the second discharge valve 8, during use, the raw material masterbatch is poured into the inside of the material cylinder 1. The motor 3 is turned on and stirred by the rotating rod 4 to increase the discharge speed of the raw material masterbatch. The bidirectional gate 17 is pushed to the top to open the first discharge valve 7, allowing the raw material masterbatch to fall into the inner box 9 inside the bottom box 5. As the weight of the raw material masterbatch increases, the inner box 9 compresses the spring 10 until the inner box 9 presses the button 13, stopping the first discharge valve 7. Then, the bidirectional gate 17 is pulled down to open the second discharge valve 8. The raw material masterbatch is lowered into the inner box 9 inside the bottom box 6. At the same time, the solenoid valve 12 at the bottom of the inner box 9 inside the bottom box 5 is opened to discharge the raw material masterbatch downward through the outlet pipe 11. The above operation is repeated until the raw material masterbatch is completely packaged. This can effectively control the weight of the raw material masterbatch precisely, avoid uneven distribution, and prevent the discharge valve at the top of the inner box 9 and the solenoid valve 12 at the bottom from opening at the same time, thus ensuring the accuracy of the raw material masterbatch packaging.

[0023] This raw material masterbatch quantitative dispensing device provides power to all electrical equipment via an external power supply. In operation, the raw material masterbatch is poured into the inner side of the hopper 1. The motor 3 is turned on, and the rotating rod 4 stirs the material, increasing the feeding speed. The bidirectional gate 17 is pushed upwards, opening the first feeding valve 7, allowing the raw material masterbatch to fall into the inner box 9 inside the bottom box 5. As the weight of the raw material masterbatch increases, the inner box 9 compresses the spring 10 until the inner box 9 presses the button 13, stopping the first feeding valve 7. Then, the bidirectional gate 17 is pulled downwards, opening the second feeding valve 8, allowing the raw material masterbatch to fall into the inner box 9 inside the second bottom box 6. Simultaneously, the solenoid valve 12 at the bottom of the inner box 9 inside the bottom box 5 is opened, discharging the raw material masterbatch downwards through the outlet pipe 11. This process is repeated until the raw material masterbatch is completely dispensed, effectively controlling the weight of the raw material masterbatch. Precise control of the quantity is achieved to avoid uneven material distribution and to prevent the simultaneous opening of the discharge valve at the top and the solenoid valve 12 at the bottom of the inner box 9, ensuring the accuracy of raw material masterbatch dispensing. When the required weight of raw material masterbatch to be dispensed changes, one lead screw 14 is rotated. The pulley 15 on the lead screw 14 drives another pulley 15 via a belt 16, which in turn drives the other lead screw 14 to rotate synchronously. The lead screw 14 drives the button 13 to rise or fall synchronously inside the first bottom box 5 and the second bottom box 6, thereby adjusting the distance between the button 13 and the inner box 9, and thus adjusting the weight control of the raw material masterbatch in the inner box 9. This not only improves the efficiency of weight control of the dispensed raw material masterbatch but also avoids inconsistent adjustment of the two buttons 13, ensuring the consistency of the weight of the raw material masterbatch dispensed in the two inner boxes 9.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
