Description
Technical Field
[0001] This utility model relates to the field of polyester chip processing technology, specifically to a polyester chip mixing and stirring device. Background Technology
[0002] Polyester chips, scientifically known as polyethylene terephthalate (PET), are an important chemical raw material produced by the polymerization reaction of purified terephthalic acid (PTA) and ethylene glycol (EG). They are typically processed into sheet-like granules of approximately 4×5×2 mm. Belonging to the category of crystalline saturated polyesters, they are milky white or light yellow, highly crystalline polymers with a smooth, glossy surface.
[0003] In the process of use, the polyester chips and powdered modifier are usually mixed and stirred to achieve the mixing process. However, in the actual mixing process, it is often necessary to continuously add powdered modifier according to the situation. The top-sprinkling method only acts on the top of the mixture and cannot reach the inside, resulting in more powder at the top and less powder at the bottom, which further reduces the mixing effect, resulting in low overall mixing efficiency and poor performance. Therefore, a polyester chip mixing and stirring device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a polyester chip mixing and stirring device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A mixing tank is included, with a top cover connected to its top. A motor frame is connected to one side of the top of the top cover, and a first motor is connected to the top of the motor frame. A modifier dispensing pipe is rotatably mounted at the central axis of the top of the top cover, with one end of the dispensing pipe penetrating the mixing tank and extending to the bottom. A funnel is connected to the top of the dispensing pipe. Pulleys are connected to both the top surface of the dispensing pipe and the output surface of the first motor, and a transmission belt is fitted between the two pulleys. A feeding pipe is connected to the top of the top cover on one side of the dispensing pipe, and a sealing cap is threaded onto the surface of the feeding pipe. Two stirring plates are connected to the surface of the dispensing pipe inside the mixing tank, and the two stirring plates are arranged opposite each other. A discharge pipe is connected to one side of the bottom of the mixing tank, and a solenoid valve is connected to the surface of the discharge pipe.
[0006] Preferably, the upper half of the inner wall of the modifier dispensing tube is connected to four first connecting rods, and a protective shell is connected between the four first connecting rods. A servo motor is connected inside the protective shell. The upper and lower half of the output end of the servo motor are both connected to second connecting rods. A blocking ring is connected to the outer side of each of the two sets of second connecting rods, and the surface of the blocking ring is in contact with the inner wall of the modifier dispensing tube. The surface of the modifier dispensing tube has multiple through holes on both sides corresponding to the protrusions of the blocking rings, and the surface of the blocking ring has through grooves on both sides corresponding to the through holes.
[0007] Preferably, a guide block is connected to the top of the protective shell, and the guide block is cone-shaped.
[0008] Preferably, a sealing plug is slidably disposed at the top of the funnel, two rubber rings are connected to the surface of the sealing plug, and a handle is connected to the top of the sealing plug.
[0009] Preferably, a connecting cover is connected to the bottom end of the modifier dispensing pipe, a support frame is connected to the bottom end of the mixing tank, an air pump is connected to the top inner side of the support frame, and the air pump blowing end passes through the connecting cover and extends into the interior of the modifier dispensing pipe.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-5 This utility model provides a technical solution, including a mixing tank 1, a top cover 2 connected to the top of the mixing tank 1, a motor frame 3 connected to one side of the top of the top cover 2, a first motor 4 connected to the top of the motor frame 3, a modifier dispensing pipe 5 rotatably mounted at the central axis of the top of the top of the top cover 2, one end of the modifier dispensing pipe 5 penetrating the mixing tank 1 and extending to the bottom of the mixing tank 1, a funnel 6 connected to the top of the modifier dispensing pipe 5, pulleys 7 connected to both the top surface of the modifier dispensing pipe 5 and the output end surface of the first motor 4, a transmission belt 8 sleeved between the two pulleys 7, a feeding pipe 9 connected to the top of the top of the top cover 2 at one side of the modifier dispensing pipe 5, a sealing cap 10 threaded on the surface of the feeding pipe 9, two stirring plates 11 connected to the surface of the modifier dispensing pipe 5 inside the mixing tank 1, the two stirring plates 11 being arranged opposite to each other, a discharge pipe 29 connected to one side of the bottom of the mixing tank 1, and a solenoid valve 30 connected to the surface of the discharge pipe 29.
[0017] Four first connecting rods 12 are connected to the upper half of the inner wall of the modifier dispensing tube 5. A protective shell 13 is connected between the four first connecting rods 12. A servo motor 14 is connected inside the protective shell 13. Second connecting rods 15 are connected to the upper and lower halves of the output end surface of the servo motor 14. A blocking ring 16 is connected to the outer side of each of the two sets of second connecting rods 15, and the surface of the blocking ring 16 is in contact with the inner wall of the modifier dispensing tube 5. Multiple through holes 17 are opened on the surface of the modifier dispensing tube 5 corresponding to the protrusions of the blocking ring 16 on both sides. Through grooves 18 are opened on the surface of the blocking ring 16 corresponding to the through holes 17 on both sides. The function of these grooves is that when the servo motor 14 is started, it will drive the second connecting rods 15 to rotate, thereby causing the blocking ring 16 to rotate. During the rotation of the blocking ring 16, the through grooves 18 will periodically align with or offset from the through holes 17 on the surface of the modifier dispensing tube 5. When the through groove 18 is aligned with the through hole 17, the modifier can smoothly pass through the through hole 17 and the through groove 18 into the mixing tank 1; when the through groove 18 is misaligned with the through hole 17, the blocking ring 16 will block the modifier from passing through, thereby achieving precise control of the amount of modifier added.
[0018] A guide block 19 is connected to the top of the protective shell 13. The guide block 19 is cone-shaped. Its function is to guide the modifier smoothly to the inner wall of the modifier dispensing pipe 5 when the modifier is added from the funnel 6, so as to avoid the modifier accumulating at the top of the protective shell 13 and make the modifier more evenly distributed inside the modifier dispensing pipe 5. This ensures that the modifier can enter the mixing tank 1 more smoothly through the through hole 17 and through groove 18, thereby improving the stability and uniformity of the modifier dispensing.
[0019] A sealing plug 20 is slidably mounted on the top of the funnel 6. Two rubber rings 21 are connected to the surface of the sealing plug 20, and a handle 22 is connected to the top of the sealing plug 20. The function of the handle 22 is to allow the sealing plug 20 to be inserted into the top of the funnel 6 via the handle 22 when the device does not need to add the modifier. At this time, the two rubber rings 21 will fit tightly against the inner wall of the funnel 6, forming a good seal. This effectively prevents external dust and impurities from entering the modifier dispensing pipe 5, avoiding contamination of the modifier. It also prevents gas or substances in the mixing tank 1 from flowing back through the modifier dispensing pipe 5, ensuring the cleanliness and stable operation of the device. Furthermore, the rubber rings 21 enhance the reliability of the seal and reduce the possibility of leakage.
[0020] A connecting cover 23 is connected to the bottom end of the modifier dispensing pipe 5, and a support frame 24 is connected to the bottom end of the mixing tank 1. An air pump 25 is connected to the top of the inner side of the support frame 24, and the air blowing end of the air pump 25 passes through the connecting cover 23 and extends into the interior of the modifier dispensing pipe 5. Its function is that when the air pump 25 is started, it blows gas into the interior of the modifier dispensing pipe 5. This gas has multiple functions. On the one hand, the gas can blow away the modifier accumulated at the bottom of the modifier dispensing pipe 5, allowing it to enter the mixing tank 1 more smoothly through the modifier dispensing pipe 5, avoiding the modifier from accumulating at the bottom of the pipe and affecting the dispensing effect. On the other hand, the blown gas can form a certain airflow in the modifier dispensing pipe 5, which helps to keep the interior of the modifier dispensing pipe 5 dry, reducing problems such as the modifier clumping that may occur due to a humid environment, ensuring that the modifier can be dispensed in good condition, thereby improving the efficiency and stability of the entire mixing process. Meanwhile, the connecting cover 23 can better guide the gas blown out by the air pump 25 into the modifier delivery pipe 5, making the gas action more concentrated and effective.
[0021] An insulating jacket 26 is fitted around the outside of the mixing tank 1. An electric heating wire 27 is connected between the surface of the mixing tank 1 and the inner wall of the insulating jacket 26. A controller 28 is connected to the surface of the insulating jacket 26 and is electrically connected to the electric heating wire 27. Its function is to precisely control the heating temperature and heating time of the electric heating wire 27 when heating of the polyester chips and modifier mixture inside the mixing tank 1 is required. When the electric heating wire 27 is energized, it generates heat and transfers it to the mixing tank 1, raising the temperature inside the mixing tank 1. The insulating jacket 26 provides good insulation, reducing heat loss and ensuring that the temperature inside the mixing tank 1 is stably maintained within the set range. This allows for the provision of a suitable temperature environment for mixing and stirring the polyester chips and modifier according to different process requirements, promoting full reaction and mixing between the two, and improving product quality and performance.
[0022] The bottom of the mixing tank 1 is connected to four support legs 31, which are arranged in a rectangular shape. Their function is to...
[0023] Four rectangular support legs 31 provide stable and reliable support for the entire mixing tank 1. During operation, whether the first motor 4 drives the modifier dosing pipe 5 to rotate for stirring, the air pump 25 blows air into the modifier dosing pipe 5, or the electric heating wire 27 heats the mixing tank 1, certain vibrations and forces will be generated. These four support legs 31 can evenly distribute these forces, ensuring that the mixing tank 1 remains stable under various operating conditions. It will not affect the normal operation of the device due to shaking or tilting, and it also ensures the safety of operators, avoiding accidents caused by device instability.
[0024] Working Principle: First, open the sealing cap 10 on the feeding pipe 9 and feed the polyester chips to be mixed into the mixing tank 1 through the feeding pipe 9. After feeding, tighten the sealing cap 10 again to ensure the sealing of the mixing tank 1. Next, pour the modifier into the funnel 6. When the modifier needs to be added, the servo motor 14 is started by the controller 28 according to the process requirements. The servo motor 14 drives the second connecting rod 15 to rotate, which in turn causes the blocking ring 16 to rotate. When the through groove 18 on the blocking ring 16 is aligned with the through hole 17 on the surface of the modifier feeding pipe 5, the modifier enters the mixing tank 1 through the through hole 17 and the through groove 18. By controlling the rotation time and frequency of the servo motor 14, the amount of modifier added can be precisely controlled. At the same time, the first motor 4 is started. The first motor 4 drives the modifier feeding pipe 5 to rotate through the pulley 7 and the transmission belt 8. The two stirring plates 11 on the modifier feeding pipe 5 rotate accordingly, stirring and mixing the polyester chips and modifier in the mixing tank 1. If the modifier is found to be accumulating at the bottom of the modifier inlet pipe 5, the air pump 25 is started. The air pump 25 blows gas into the modifier inlet pipe 5 to dislodge the accumulated modifier and allow it to flow more smoothly into the mixing tank 1. When it is necessary to heat the mixture in the mixing tank 1, the electric heating wire 27 is energized by the controller 28 to heat up and transfer heat to the mixing tank 1. The insulation jacket 26 provides insulation, keeping the temperature in the mixing tank 1 stable within the set range, promoting the full reaction and mixing of the polyester chips and the modifier. After mixing and stirring are completed, the solenoid valve 30 on the discharge pipe 29 is opened to discharge the mixed material from the discharge pipe 29. Throughout the entire operation, the four support legs 31 provide stable support for the mixing tank 1, ensuring the smooth operation of the device.
