[0001] This utility model relates to the field of color masterbatch discharge device, and in particular to a color masterbatch discharge device. Background Technology
[0002] When discharging color masterbatch, a color masterbatch discharging device is often used. This device is a specialized piece of equipment designed to accurately, stably, and efficiently output color masterbatch from storage containers. It typically features functions such as precise metering and uniform discharging, ensuring that color masterbatch is accurately output according to a set ratio during plastic processing and other production processes. This allows for precise color matching and control of plastic products. The benefits of using this device are significant. On the one hand, it can greatly improve production efficiency. Through automated and precise discharging operations, it reduces manual intervention, avoids inaccurate or unstable discharging caused by human factors, and ensures the continuity of the production process and the consistency of product quality.
[0003] A search revealed that Chinese application number CN2021222535292 discloses a constant pressure discharge device for biodegradable masterbatch, comprising a barrel with a lid at the top and a connecting pipe connected by a flange at the middle of the lower part of the barrel. A transition tank is fixedly connected to the lower end of the connecting pipe, and a discharge pipe is located at the lower end of the transition tank. The barrel, connecting pipe, transition tank, and discharge pipe are all interconnected. A slidable hopper is installed inside the barrel. The hopper is conical with open ends and a sliding connection assembly is provided between the hopper and the barrel. A movable pipe is vertically fixedly connected to the lower opening of the hopper, and the lower end of the movable pipe is slidably connected to the connecting pipe. This invention ensures constant internal air pressure, stabilizes uniform discharge, improves color uniformity, and stabilizes the internal air pressure of the barrel, thus avoiding blockage in the discharge pipe and ensuring smooth discharge.
[0004] The patent description states that "as the hopper gradually moves upward, it drives the moving tube upward, causing the sliding pin to rotate relative to each other inside the moving tube, which in turn drives the agitator plate at the bottom to slowly tumble, thus avoiding blockage in the discharge tube to a certain extent and ensuring smooth discharge." Although it can achieve the effect of preventing blockage to a certain extent, there may be impurities and raw materials adhering inside the discharge tube, which will affect subsequent discharge and cause blockage to a certain extent. Utility Model Content
[0005] The present invention proposes a masterbatch discharge device, which aims to improve the problem that some existing devices cannot prevent blockage and clean residual materials on the barrel wall during masterbatch discharge.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A masterbatch discharging device includes a material hopper. A feed inlet is fixedly connected to the top right side of the hopper. A docking mechanism is provided on the outer wall of the feed inlet. A pressure gauge is fixedly connected to the top left side of the hopper. A cleaning mechanism is provided on the top of the hopper. The docking mechanism includes an extension tube. Fixing buckles are fixedly connected to the left and right sides of the outer wall of the extension tube. A limit rod is fixedly connected to the right side of the outer wall of the fixing buckle. A limit assembly is provided at the top of the fixing buckle. A fixing block is provided at the bottom of the limit assembly. A support spring is fixedly connected to the bottom of the fixing block. A connecting tube is fixedly connected to the right side of the outer wall of the extension tube. The left side of the outer wall of the extension tube is fixedly connected to the right side of the outer wall of the feed inlet. The outer wall of the support spring is fixedly connected to the inside of the fixing buckle.
[0008] The above solution provides a masterbatch discharging device, including a material barrel with a feed inlet on the top right side and a docking mechanism, a pressure gauge on the left side, and a cleaning mechanism on the top. The docking mechanism has an extension tube connected to the feed inlet, and its outer wall has a fixing buckle, a limiting rod, and a limiting component that work together. A support spring buffers external forces, and the connecting tube facilitates docking with external feeding equipment. In this device, the docking mechanism achieves a quick and stable connection, reducing leakage; the pressure gauge monitors the pressure inside the barrel in real time, ensuring safety; and the cleaning mechanism facilitates cleaning residues inside the barrel, improving efficiency and effectively meeting various needs during the masterbatch discharging process.
[0009] As a further description of the above technical solution:
[0010] The cleaning mechanism includes a housing, inside which a drive assembly is provided. A stirring plate is provided at the bottom of the drive assembly. Fixing blocks are fixedly connected to the left and right sides of the outer wall of the stirring plate. A follower rod is fixedly connected to the right side of the outer wall of the fixing blocks. A connecting rod is rotatably connected inside the follower rod. A scraper is fixedly connected to the left side of the outer wall of the follower rod.
[0011] Through the above solution: In the cleaning mechanism, the drive component inside the outer shell drives the stirring plate to rotate. The fixed block two, the follower rod and the connecting rod work together to make the scraper move against the inner wall of the material bucket. The stirring plate can fully stir the masterbatch before it is discharged to avoid clumping. When rotating, the scraper can effectively scrape off the residual masterbatch on the inner wall of the material bucket to prevent material adhesion and accumulation. The two work together to ensure that the masterbatch is discharged evenly and that the bucket wall can be cleaned in time after use, reducing material waste, reducing the intensity of manual cleaning, improving the efficiency and cleanliness of the device, extending the service life of the material bucket, and optimizing the whole process of masterbatch discharge.
[0012] As a further description of the above technical solution:
[0013] The limiting component includes a limiting sleeve, the outer wall of which is fixedly connected to the outer wall of the fixing buckle, and a movable rod is fixedly connected to the inner space of the limiting sleeve, the bottom of which is fixedly connected to the top of the fixing block.
[0014] Through the above solution: In the cleaning mechanism, the drive component inside the outer shell drives the stirring plate to rotate. The fixed block two, the follower rod and the connecting rod work together to make the scraper move against the inner wall of the material bucket. The stirring plate can fully stir the masterbatch before it is discharged to avoid clumping. When rotating, the scraper can effectively scrape off the residual masterbatch on the inner wall of the material bucket to prevent material adhesion and accumulation. The two work together to ensure that the masterbatch is discharged evenly and that the bucket wall can be cleaned in time after use, reducing material waste, reducing the intensity of manual cleaning, improving the efficiency and cleanliness of the device, extending the service life of the material bucket, and optimizing the whole process of masterbatch discharge.
[0015] As a further description of the above technical solution:
[0016] The drive assembly includes a motor, the outer wall of which is fixedly connected to the inside of the housing, and a transmission rod is fixedly connected to the output end of the motor. The left and right sides of the outer wall of the stirring plate are fixedly connected to the outer wall of the transmission rod.
[0017] With the above solution: the motor is securely installed in the outer casing of the drive assembly, and its output end is connected to the mixing plate through the transmission rod. After the motor is started, the transmission rod drives the mixing plate to rotate at high speed. On the one hand, it can fully mix the masterbatch evenly, improve the output quality, and ensure the stability of the material performance. On the other hand, the mixing process can effectively break up lumpy materials and avoid clogging the discharge port. At the same time, the rotation of the mixing plate drives the scraper to operate synchronously, realizing the integration of mixing and cleaning, reducing the frequency of equipment maintenance, reducing labor costs, and greatly improving the overall working efficiency and practicality of the masterbatch discharge device.
[0018] As a further description of the above technical solution:
[0019] The material barrel has a fixedly connected material hopper in its internal space, and a screening component is provided in the internal space of the material barrel. The outer wall of the stirring plate is rotatably connected to the inside of the material hopper.
[0020] The above solution involves setting up a hopper and a screening component inside the material bucket. The stirring plate rotates inside the hopper, which facilitates centralized stirring of the masterbatch. The screening component can filter out unqualified particles, ensuring the quality of the output. The two work together to achieve integrated stirring and screening, improving the quality of the masterbatch, reducing subsequent processing problems, and increasing production efficiency.
[0021] As a further description of the above technical solution:
[0022] The screening assembly includes a baffle plate, a filter plate is fixedly connected inside the material barrel, and the outer wall of the baffle plate is fixedly connected inside the material barrel.
[0023] The above scheme involves a baffle plate and a filter plate fixed inside the material hopper in the screening assembly. When the masterbatch falls, the baffle plate changes the material flow path, causing it to disperse and pass through the filter plate. The filter plate screens the masterbatch, intercepting materials with incorrect particle size or agglomerated particles, while qualified materials pass through smoothly. This design effectively prevents unqualified particles from entering the discharge stage, ensuring the uniformity of the masterbatch quality. At the same time, the baffle plate extends the material residence time, which, combined with the stirring plate, further improves the screening effect, reduces the cost of secondary manual screening, and optimizes the practicality and reliability of the discharge device.
[0024] As a further description of the above technical solution:
[0025] A discharge port is fixedly connected to the left side of the outer wall of the filter plate. A discharge slide is provided inside the discharge port, and the outer wall of the discharge port is fixedly connected to the inside of the material barrel.
[0026] The above solution involves a discharge chute on the left side of the filter plate, which is securely connected to the material hopper. Qualified masterbatch after screening by the filter plate can slide smoothly out along the discharge chute. The chute design effectively guides the directional flow of materials, reducing accumulation and blockage. At the same time, the discharge port is tightly fixed to the material hopper, ensuring good sealing during the discharge process and preventing leakage of masterbatch. This structure optimizes the discharge process, enabling efficient output of screened masterbatch, improving the overall discharge efficiency of the device, reducing material loss, and providing a stable and convenient supply guarantee for subsequent production processes.
[0027] As a further description of the above technical solution:
[0028] The outer wall of the stirring plate is rotatably connected to the inside of the material barrel, and the outer wall of the scraper is rotatably connected to the inside of the material barrel.
[0029] The above solution involves the mixing plate and scraper rotating inside the material bucket. The mixing plate thoroughly mixes the masterbatch, ensuring material uniformity, while the scraper closely adheres to the bucket wall to remove residues, preventing material accumulation and clumping. The two work together to improve the quality of the output, reduce material waste, ensure the cleanliness of the inside of the material bucket, lower maintenance costs, and improve the efficiency of the equipment.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, the position of the connecting pipe is precisely limited by the limiting rod, which effectively avoids docking misalignment and ensures the accuracy and stability of the masterbatch conveying path. The moving rod in the limiting component, together with the limiting sleeve, can flexibly control the position of the fixing block one. The compression degree of the support spring can be adjusted according to actual needs, so that the device has good adaptability and flexibility. Under the action of the support spring, the fixing buckle can strongly clamp the extension pipe to form a stable feeding channel, which not only effectively prevents material leakage, but also ensures that the masterbatch is efficiently and continuously conveyed to the material barrel for storage, significantly improving the reliability and working efficiency of the feeding process.
[0032] 2. In this utility model, through the synergistic design of stirring and scraping, the stirring plate and transmission rod driven by the motor can effectively prevent the color masterbatch from accumulating in the material bucket, and can also clean the residual material by the scraper closely adhering to the bucket wall, ensuring the uniformity of material processing and the cleanliness of the material bucket. At the same time, the baffle plate, filter plate and discharge slide in the screening component can disperse, screen the particle size and separate impurities of the color masterbatch entering the material bucket, ensuring the quality of the output color masterbatch, improving production efficiency and product quality, reducing production failures and product defects caused by material agglomeration and impurity mixing, and realizing the efficient integrated operation of material processing and screening.

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.
[0040] Reference Figures 1 to 2This utility model provides an embodiment of a masterbatch discharging device, including a material tank 1, which serves as a storage container for the masterbatch and provides space for mixing and discharging. A feed inlet 2 is fixedly connected to the top right side of the material tank 1, providing a channel for the masterbatch to enter the material tank 1 and an inlet for conveying the masterbatch. A docking mechanism 3 is provided on the outer wall of the feed inlet 2 to connect the feed inlet 2 to an external masterbatch conveying pipe, ensuring smooth feeding.

When the pressure exceeds a set value, an alarm can be issued promptly to remind the operator to take appropriate measures. To ensure production safety, appropriate measures are taken. A cleaning mechanism 5 is installed on the top of the material hopper 1 to regularly clean the inside of the hopper 1, preventing masterbatch residue and clumping, and ensuring the cleanliness of the hopper 1 and the quality of the masterbatch. The docking mechanism 3 includes an extension tube 31, which serves as a transition component between the inlet 2 and the connecting tube 37. The extension tube 31 extends the feeding channel, facilitating docking with external conveying pipes. Fixing buckles 32 are fixedly connected to the left and right sides of the outer wall of the extension tube 31, providing an installation base for the limiting rod 33 and the limiting component 34. The clamping action of the fixing buckles 32 ensures the connection between the extension tube 31 and the inlet. 2. To ensure the stability of the connection between the connecting pipe 37 and the fixing buckle 32, a limiting rod 33 is fixedly connected to the right side of the outer wall of the fixing buckle 32 to limit the position of the connecting pipe 37, prevent the connecting pipe 37 from shifting during the docking process, and ensure the accuracy and stability of the connection. A limiting component 34 is provided at the top of the fixing buckle 32, which consists of a limiting sleeve 341 and a moving rod 342, and is used to limit and adjust the fixing block 35. The fixing block 35 is provided at the bottom of the limiting component 34, which is the fixed end of the supporting spring 36. One end of the supporting spring 36 is fixed inside the fixing buckle 32 and connected to the moving rod 342 to transmit the movement. The force of the moving rod 342, the bottom of the fixed block 35 is fixedly connected to the support spring 36, which provides support force through elastic deformation, so that the fixing buckle 32 can tightly clamp the extension tube 31, and at the same time play a buffering role in the docking process to reduce the impact force during docking. The right side of the outer wall of the extension tube 31 is fixedly connected to the connecting pipe 37 for connecting to the external conveying pipe, so that the color masterbatch is introduced from the external conveying pipe into the extension tube 31 and then into the material barrel 1. The left side of the outer wall of the extension tube 31 is fixedly connected to the right side of the outer wall of the feed port 2, and the outer wall of the support spring 36 is fixedly connected to the inside of the fixing buckle 32.
[0041] Specifically, a masterbatch discharging device has a core component of a material barrel 1. A feed inlet 2 is located on the top right side of the barrel, and a docking mechanism 3 is located on the outer wall to connect to an external conveying pipeline to ensure smooth feeding. A pressure gauge 4 is installed on the top left side to monitor the pressure in real time and trigger an alarm if the pressure exceeds a set value, ensuring production safety. A cleaning mechanism 5 is also located on the top to periodically clean the inside of the barrel and prevent masterbatch residue from clumping. The docking mechanism 3 includes an extension tube 31 to extend the feed channel for convenient docking, and fixing buckles 32 on both sides of its outer wall provide a mounting base for limiting components. The limiting rod 33 prevents the connecting pipe 37 from shifting during docking. The limiting component 34 consists of a limiting sleeve 341 and a moving rod 342, which limits and adjusts the fixed block 35. The fixed block 35 fixes one end of the support spring 36. The support spring 36 provides support force and buffer through elastic deformation. The connecting pipe 37 is connected to an external pipe to introduce masterbatch. The left side of the extension pipe 31 is fixed to the feed port 2. The support spring 36 is fixed in the fixing buckle 32. All components of the device work together to ensure stable operation of masterbatch storage, feeding and other processes.
[0042] The cleaning mechanism 5 includes a housing 51, which serves as a protective cover for the drive assembly 52, preventing dust and impurities from entering and providing a stable working environment for the drive assembly 52. The drive assembly 52 is housed inside the housing 51, transmitting rotational motion to the stirring plate 53 via a motor 521 and a transmission rod 522 to drive the cleaning action. The stirring plate 53 is located at the bottom of the drive assembly 52. Driven by the drive assembly 52, the stirring plate 53 rotates within the material tank 1, stirring the masterbatch to prevent clumping and accumulation. Simultaneously, it drives the follower rod 55 and scraper 57 to move, cleaning the inner wall of the material tank 1. Fixing blocks 54 are fixedly connected to the left and right sides of the outer wall of the stirring plate 53, serving as the mounting base for the follower rod 55 and providing fixing points for the follower rod 55. The rod 55 can move with the rotation of the stirring plate 53. The right side of the outer wall of the fixed block 54 is fixedly connected to the follower rod 55. Under the drive of the stirring plate 53, the follower rod 55 rotates with the stirring plate 53 and achieves a certain angle change through the rotation connection, so that the scraper 57 can better fit against the inner wall of the material bucket 1 for cleaning. The follower rod 55 is rotatably connected to the inside of the follower rod 55, which is the support and rotation shaft of the follower rod 55 and provides the fulcrum for the rotation of the follower rod 55, so that the follower rod 55 can move stably in the material bucket 1. The left side of the outer wall of the follower rod 55 is fixedly connected to the scraper 57. Under the drive of the follower rod 55, the scraper 57 scrapes against the inner wall of the material bucket 1 to clean the residual masterbatch adhering to the inner wall of the material bucket 1, ensuring the cleanliness of the inner wall of the material bucket 1.
[0043] Specifically, the outer shell 51 serves as a protective cover for the drive component 52, isolating dust and impurities and creating a stable working environment. The drive component 52 inside the outer shell 51 transmits the rotational motion to the stirring plate 53 through the motor 521 and the transmission rod 522, driving the cleaning operation. The stirring plate 53 rotates inside the material bucket 1, which can both stir the masterbatch to prevent clumping and accumulation, and drive the follower rod 55 and the scraper 57 to move. The fixing block 54 on the outer wall of the stirring plate 53 provides a mounting point for the follower rod 55. The follower rod 55 rotates under the drive of the stirring plate 53, and its internal connecting rod 56 serves as a rotation fulcrum, making the movement of the follower rod 55 stable. The scraper 57 driven by the follower rod 55 scrapes against the inner wall of the material bucket 1, which can effectively clean the masterbatch residue and ensure that the inner wall of the material bucket 1 is clean.
[0044] Reference Figures 2 to 3 The limiting component 34 includes a limiting sleeve 341, which provides guidance and support for the moving rod 342, ensuring that the moving rod 342 can move smoothly inside it. The outer wall of the limiting sleeve 341 is fixedly connected to the outer wall of the fixing buckle 32. The moving rod 342 is fixedly connected to the space area inside the limiting sleeve 341. By moving inside the limiting sleeve 341, the position of the fixing block 35 is controlled, thereby adjusting the compression degree of the support spring 36 to achieve the purpose of limiting and fixing. The bottom of the moving rod 342 is fixedly connected to the top of the fixing block 35. The driving component 52 includes a motor 521, which is the driving source and provides power to the cleaning mechanism 5. The rotation of the output shaft drives the transmission rod 522 to rotate, thereby driving the stirring plate 53 to move. The outer wall of the motor 521 is fixedly connected to the space area inside the limiting sleeve 341. Inside the outer casing 51, the output end of the motor 521 is fixedly connected to a transmission rod 522, which transmits the power of the motor 521 to the stirring plate 53, enabling the stirring plate 53 to rotate within the material barrel 1 to achieve a cleaning function. The outer walls of the stirring plate 53 are fixedly connected to the outer walls of the transmission rod 522 on both the left and right sides. A hopper 58 is fixedly connected to the internal space of the material barrel 1. The hopper 58 serves to concentrate and buffer the masterbatch. When the masterbatch enters the material barrel 1 from the feed inlet 2, it first falls into the hopper 58 to avoid directly impacting the stirring plate 53 and the bottom of the material barrel 1. A screening component 59 is provided in the internal space of the material barrel 1 to screen the masterbatch by particle size and separate impurities, ensuring that it enters the discharge outlet 593. The outer wall of the stirring plate 53 is rotatably connected to the inside of the hopper 58.
[0045] Specifically, in the limiting component 34, the limiting sleeve 341 is fixed on the fixing buckle 32, serving as a guide and support for the moving rod 342. The movement of the moving rod 342 within the sleeve controls the position of the fixing block 35. Adjusting the compression of the support spring 36 achieves limiting and fixing. In the drive component 52, the motor 521 serves as a power source and is fixed inside the outer casing 51. Its output shaft drives the transmission rod 522, thereby causing the stirring plate 53 to rotate within the material bucket 1 to complete the cleaning. The hopper 58 inside the material bucket 1 can centrally buffer the masterbatch, preventing it from directly impacting the stirring plate 53 and the bottom of the bucket. The screening component 59 can screen the masterbatch particle size and separate impurities. Furthermore, the outer wall of the stirring plate 53 is rotatably connected to the inside of the hopper 58, ensuring smooth movement.
[0046] Reference Figures 3 to 4 The screening component 59 includes a baffle plate 591, which changes the falling trajectory of the masterbatch, causing the masterbatch to collide and rub against each other during the falling process, thereby dispersing the agglomerated masterbatch. A filter plate 592 is fixedly connected inside the material tank 1, which filters impurities and particles that do not meet the particle size requirements in the masterbatch. The outer wall of the baffle plate 591 is fixedly connected inside the material tank 1. The left side of the outer wall of the filter plate 592 is fixedly connected to the discharge port 593, which is the channel for qualified masterbatch to leave the material tank 1 and transport the screened masterbatch to the external production equipment. The discharge port 593 has a discharge slide 594 inside, which guides the masterbatch to flow out smoothly from the discharge port 593 and avoids the masterbatch from accumulating in the discharge port 593. The outer wall of the discharge port 593 is fixedly connected inside the material tank 1. The outer wall of the stirring plate 53 is rotatably connected inside the material tank 1. The outer wall of the scraper 57 is rotatably connected inside the material tank 1.
[0047] Specifically, in the screening component 59, the baffle plate 591 is fixed inside the material barrel 1, which can change the falling trajectory of the masterbatch and disperse the agglomerated masterbatch through collision and friction. The filter plate 592 is also fixed inside the material barrel 1 and is used to filter impurities and unqualified particles in the masterbatch. The discharge port 593 connected to the left side of the filter plate 592 is the output channel of qualified masterbatch, which can send the screened masterbatch to external production equipment. The discharge chute 594 in the discharge port 593 can guide the masterbatch to flow out smoothly and prevent it from accumulating in the discharge port 593. In addition, the outer walls of the stirring plate 53 and the scraper 57 are rotatably connected to the inside of the material barrel 1. The stirring plate 53 can assist in stirring, and the scraper 57 is used to clean the barrel wall, together ensuring the orderly operation of the masterbatch processing in the material barrel 1.
[0048] Working principle: The masterbatch is connected to the connecting pipe 37 through the external conveying pipe, and enters the extension pipe 31 through the connecting pipe 37. The extension pipe 31 extends the feeding channel as a transition component, conveying the masterbatch to the feeding port 2, and then into the material bucket 1 for storage. During the docking process, the limiting rod 33 restricts the position of the connecting pipe 37 to prevent deviation. The moving rod 342 in the limiting component 34 moves in the limiting sleeve 341 to control the position of the fixing block 35 and adjust the compression degree of the support spring 36. The fixing buckle 32 clamps the extension pipe 31 under the action of the support spring 36 to ensure smooth feeding.
[0049] When the cleaning mechanism 5 is working, the motor 521 inside the outer casing 51 serves as the drive source, driving the transmission rod 522 to rotate through the output shaft. The transmission rod 522 drives the stirring plate 53 to rotate inside the material bucket 1. The stirring plate 53 drives the fixed block 54, the follower rod 55, and the scraper 57 to move. The stirring plate 53 stirs the masterbatch in the material bucket 1 to prevent agglomeration and accumulation. At the same time, the follower rod 55 drives the scraper 57 to scrape and clean the residual masterbatch against the inner wall of the material bucket 1. After the masterbatch enters the material bucket 1 from the feed inlet 2, it first falls into the hopper 58. The baffle plate 591 changes the falling trajectory of the masterbatch to disperse it. The filter plate 592 filters impurities and particles that do not meet the particle size requirements. The qualified masterbatch flows out to the external production equipment through the discharge chute 594 of the discharge outlet 593. The screening component 59 realizes the particle size screening and impurity separation of the masterbatch.
