TECHNICAL FIELD
[0001] The present application relates to the field of injection molding processing, and particularly to a toner delivery device based on weight. BACKGROUND
[0002] In the existing injection molding process, when realizing non-transparent colored plastic products, two main methods are usually used to achieve color control: one is to use color masterbatch, and the other is to use the mixing method of toner and base plastic. Color masterbatch is a kind of masterbatch that has been specially colored, which is in the form of granules and is uniformly mixed by base plastic and colorant under precise proportioning. Its main advantage lies in strong color stability, which can ensure the color consistency of the final injection molded product. However, the cost of color masterbatch is relatively high, especially in the case of multiple color types, large amount of use and frequent color switching, the use of color masterbatch will greatly increase the production cost, thereby making it difficult to popularize and apply in some cost-sensitive production fields. In contrast, the toner method is widely used due to its lower economic cost. Toner is a fine powder particle of different colors, which can be mixed with base plastic (such as transparent or white plastic particles) to achieve color control.
[0003] However, in the process of using the toner mixing method for injection molding, the control of color always faces great challenges and uncertainties. The purpose of toner is to be uniformly mixed with plastic particles before injection molding to obtain injection molded products that meet the specific color requirements. Therefore, the supply amount and uniformity of mixing of toner have a crucial impact on the color of the final product. However, currently, the method of fixed volume feeding is generally used in toner supply, that is, the structure of gear cooperation with fixed plate is used, and the gear groove is used as a fixed volume cavity to output toner. Although this method is relatively simple in structure and easy to implement, it has several significant shortcomings, making it difficult to achieve the expected effect of color control of the final product.
[0004] Firstly, the fixed volume powder feeding has a large deficiency in the precision of delivery. The principle of gear powder feeding is to deliver a certain volume of toner from the storage cavity to the mixing stage through the rotation of the gear, and the small gap between the gear groove and the fixed plate will make the amount of toner output slightly different each time. This inaccuracy mainly comes from the mechanical structure error between the gear and the plate and the uneven distribution of toner in the gear groove. In the process of injection molding production, since the precision of the gear structure cannot completely eliminate any gap, and the amount of powder fed into each feeding chamber may also be different, therefore, the amount of toner output by the gear in each rotation will have a certain fluctuation. These small errors will gradually accumulate over multiple powder feedings, ultimately affecting the color of the plastic product, especially in continuous production, the fluctuation of toner amount will cause a large difference in color between the injection molded products, significantly affecting the consistency and quality of the products.
[0005] Secondly, the existing fixed volume cavity powder supply structure is an active cavity, with a gear as the active end and a slotted base plate as the fixed end. This design is prone to extrusion of toner during toner delivery, especially during gear rotation. Under mechanical extrusion, toner can form clumps. This clumping phenomenon directly affects the uniform mixing of toner and base plastic, resulting in insufficient dispersion of toner during mixing, thereby producing obvious color spots and color differences in injection molded products. This problem is very common in actual production, especially for fine toner particles, which are more prone to clumping due to mechanical movement, resulting in poor mixing uniformity and color unevenness on the surface of injection molded products, severely affecting the appearance and market acceptance of the products.
[0006] In addition to delivery accuracy and clumping problems, the existing powder supply structure also has difficulty in achieving real-time dynamic adjustment. During production, the physical properties of the base plastic may be affected by factors such as raw material batch, environmental humidity, etc., requiring dynamic adjustment of toner supply. However, the current fixed volume powder supply method is difficult to accurately control and dynamically adjust the toner quantity, and the fixed nature of the mechanical structure leads to hysteresis and inaccuracy in delivery quantity adjustment, further exacerbating color deviation. Moreover, due to the instability of toner supply, workers need to frequently adjust and correct the color manually, increasing labor costs during production and affecting production efficiency and product output.
[0007] Based on the above-mentioned deficiencies in the prior art, it is of great significance to develop a toner delivery device based on weight measurement. Invention content
[0008] The purpose of the present application is to at least overcome one deficiency in the prior art, and to provide a toner delivery device based on weight.

This method can significantly improve the accuracy of toner delivery compared to the traditional fixed volume supply method, ensuring consistent toner quantity for each supply and eliminating toner quantity fluctuations caused by mechanical structure errors. In addition, the weight-based powder supply method does not extrude toner during toner delivery, effectively preventing toner clumping and ensuring uniformity during mixing of toner and base plastic.

[0013] Also to facilitate color change for injection molding, as an optional technical solution, the vibrating feeding assembly is slidingly installed on a linear slide rail with locking, and the discharge pipe / tank can approach or move away from the metering discharge assembly along the linear slide rail, so that the discharge pipe / tank can be easily detached for cleaning.
[0014] To realize more stable and reliable material discharge, as an optional technical solution, a detachable material limiting plate is inserted into the discharge pipe / tank close to the opening, the material limiting plate is used for adjusting and controlling the caliber of the material flow path at the outlet, and prevents the material from piling up at the outlet during horizontal inertial motion.

[0015] To further prevent the material from uncontrollably falling out of the opening, as an optional technical solution, an opening and closing mechanism for controlling the opening and closing state of the opening of the discharge pipe / tank is installed.

[0040] The present embodiment provides a weight-based toner delivery device, which is specially designed for automated production environments that require precise control of material delivery and metering. The device has wide application value in precision production fields such as color matching, injection molding, etc., and can achieve precise feeding, metering and blending of materials to meet high-standard production requirements. The device, through a precise feedback control system, cooperates with the vibration feeding assembly and the weighing discharge assembly to accurately control the delivery rate and weight of the material, ensuring the stability and consistency of the material delivery process.
[0041] It should be noted that the following material refers to toner.
[0042] Referring to the accompanying drawings Figures 1-3 As shown in the drawings, the vibration feeding assembly 1 is the core part of the material delivery process in the device, responsible for delivering the material from the hopper 101 to the weighing discharge assembly 2.
[0043] The core power source of the vibrating feeding assembly 1 is the vibration source 102, which is usually an electromagnetic vibration table that converts electrical energy into mechanical vibration and promotes the movement of materials along the conveying path by exciting the periodic vibration of the discharge pipe 103 or the discharge chute.
[0044] It should be understood that the working principle of the vibration source 102 is to use electromagnetic force or air flow pulsation to make the discharge pipe 103 produce continuous vibration, thereby overcoming the friction between the material and the pipe and pushing the material to flow. The adjustment of vibration frequency and amplitude can finely adapt to the flow characteristics of different materials, ensuring that the material flows at a uniform and smooth speed, avoiding the accumulation or uneven flow of the material.
[0045] Referring to the accompanying drawings Figure 4 and 5 The specific structural design of the vibration source 102 includes an electromagnetic vibration table 1001 and a mounting jig 1002 installed on the vibration end of the electromagnetic vibration table 1001. The electromagnetic vibration table 1001 is the core component of the vibration source, which converts electrical energy into mechanical vibration to provide the necessary power for material conveying. The working principle of the electromagnetic vibration table 1001 is based on electromagnetic induction, and the electromagnetic coil in the electromagnetic vibration table 1001 generates a magnetic field through the interaction with the electric current and drives the vibration end to produce periodic vibration. The vibration end is connected with the mounting jig 1002, and the mounting jig 1002 is used to fix the discharge pipe 103, ensuring that the vibration of the vibration end can be directly transmitted to the discharge pipe 103, thereby realizing accurate conveying of the material. The design of the mounting jig 1002 should consider stability and adjustability to ensure that the discharge pipe 103 can be firmly installed on the vibration end, and the adjustment of the vibration source will not cause unnecessary damage to the discharge pipe.
[0046] In order to prevent toner from scattering and polluting the air, the discharge pipe 103 and the weighing discharge assembly 2 are usually arranged in a sealed chamber, which is not shown in the figure, but its role is to isolate the external environment and prevent the material from overflowing or falling during the conveying process. The discharge pipe 103 is inserted into the chamber and cooperates with the weighing discharge assembly 2, ensuring that the material can be stably conveyed to the weighing discharge assembly in a sealed environment, thereby effectively preventing toner from polluting the air and maintaining the accuracy of the weighing.
[0047] In order to facilitate cleaning and replacement of the discharge pipe 103, the electromagnetic vibration table 1001 is installed on the base table 1004 with a linear slide rail 1003. Through this design, the electromagnetic vibration table 1001 and its matching discharge pipe 103 can slide linearly on the base table 1004, so as to realize convenient disassembly and replacement of the discharge pipe. When material replacement or cleaning is needed, the operator only needs to move the vibration table along the slide rail 1003, and withdraw the discharge pipe 103 from the sealed chamber, so as to facilitate cleaning or replacement operation. In order to ensure that the discharge pipe 103 can maintain a fixed position during work, the linear slide rail 1003 is provided with a locking function. The locking function can accurately lock the position of the discharge pipe 103 during use, avoid deviation or vibration during material conveying, ensure the docking accuracy of the discharge pipe and the weighing and discharging assembly 2, and thus ensure the stability of the conveying process and the accurate metering of the material.
[0048] In order to avoid the self-flow of the material in the static state, the discharge pipe 103 is usually designed to have a certain inclination angle. In actual application, the inclination of the discharge pipe 103 is realized by the installation jig 1003. The purpose of the upward inclination is to prevent the material from flowing disorderly when it is not subjected to vibration. The excitation action of the vibration source makes the flow of the material in the pipe stable and controllable, and ensures that the material can be accurately and reliably conveyed to the weighing and discharging assembly. In design, the inner surface of the discharge pipe / slot is usually made of smooth and anti-sticking material, which further reduces the friction and ensures smooth flow of the material.
[0049] In order to adapt to different requirements in the production environment, especially the frequent color change requirement, the embodiment also considers the cleaning convenience of the equipment. The discharge pipe 103 and the jig 1003 are detachably connected, which facilitates cleaning during material replacement and avoids the influence of material residues on the next production.
[0050] On the basis of the above structure, since the toner delivery device in the embodiment is usually installed on an injection molding machine for use, when the injection molding machine performs horizontal mold opening and closing operation, the device will produce horizontal displacement with the movement of the injection molding machine. In this process, the material may accumulate at the opening of the discharge pipe 103 due to its inertia, which may cause unstable flow of the material, and even a large amount of material may suddenly flow out when vibration is needed, thereby affecting the accuracy and stability of material conveying. In order to avoid this phenomenon and further improve the stability and accurate control ability of the system, the embodiment is provided with an adjustable material limiting plate 1007 on the discharge pipe 103, which solves this problem.
[0051] Referring to the drawings Figure 6The limiting plate 1007 is obliquely inserted into the discharge pipe 103 and is positioned close to the outlet of the discharge pipe 103, thereby precisely controlling the diameter of the discharge pipe. By installing the limiting plate, an adjustable limiting structure is formed, which can precisely adjust the size of the discharge path according to actual needs, thereby controlling the path and flow of the material flow. The presence of the limiting plate 1007 effectively prevents the accumulation of material during transportation, especially when the injection molding machine is opened and closed, thereby avoiding excessive accumulation or blockage due to material inertia.
[0052] To further improve the precise control capability of the system, an opening and closing mechanism is provided at the opening of the discharge pipe 103. The opening and closing mechanism includes a baffle 1005 cooperating with the opening of the discharge pipe and a cylinder 1006 driving the movement of the baffle 1005. The baffle 1005 is used to precisely control the opening and closing state of the discharge pipe, and the cylinder 1006 drives the movement of the baffle 1005 through air pressure. According to the needs of the system, the cylinder can quickly adjust the opening and closing state of the baffle, thereby controlling the start or stop of the material flow. When the material flow is needed, the cylinder moves the baffle away to allow the material to pass; when the material flow is not needed, the cylinder drives the baffle to close the discharge opening to prevent the material from flowing out.
[0053] Through the cooperation of the limiting plate 1007 and the opening and closing mechanism, the system can more accurately regulate the flow and transportation speed of the material, avoiding problems such as material accumulation and unstable flow caused by the movement of the injection molding machine. The limiting plate ensures the control of the outlet and prevents uneven flow of the material due to inertia; the opening and closing mechanism provides a more efficient and flexible material flow control method, allowing the entire system to flexibly adjust the transportation amount of the material according to production needs, ensuring accurate and stable material delivery.
[0054] In this embodiment, reference is made to the accompanying drawings Figure 7 and 8 The weighing and discharging assembly 2 mainly consists of a rotary drive mechanism 201, a weighing module 202 and an open container 203.
[0055] The rotary drive mechanism 201 is responsible for precisely controlling the rotary motion of the open container 203, ensuring that the material can be accurately poured out. After the material is transported to the open container 203 by the vibrating feeder assembly 1, the weighing module 202 will monitor the weight of the material in the container in real time. The weighing sensor in the weighing module generally uses a strain or piezoelectric sensor, which can convert the weight change of the material into an electrical signal and transmit it to the external control system (not shown in the figure).
[0056] According to the weight signal feedback by the weighing sensor, the control system can adjust the working state of the vibrating feeder assembly in real time, thereby precisely controlling the amount of material transported each time and ensuring that the weight of the material in the open container 203 reaches the predetermined target.
[0057] It needs to be understood that the weighing module 202 is the core of the weighing discharge assembly 2, which monitors the weight change of the material in real time through the weighing sensor installed on the open container 203. In actual operation, the entire material conveying and weighing process is a closed-loop feedback process. Specifically, the feeding, weighing and feedback information of the material are interrelated, forming a continuous adjustment and calibration process until the preset target weight is reached.
[0058] The weighing discharge assembly 2 has two modes of operation. One is when the vibrating feeder assembly 1 starts to work, the vibration source 102 causes the material to be conveyed along the discharge pipe 103 to the open container 203 of the weighing discharge assembly 2. During the conveying process, the amplitude and frequency of the vibration are adjusted according to the flow characteristics of the material, so as to ensure that the material flows uniformly and stably into the open container 203. At this time, the flow rate and stability of the material are precisely controlled to avoid any unnecessary fluctuations.
[0059] When the material enters the open container 203, the weighing module 202 monitors the weight of the material through the sensor. The weighing sensor converts the change in the weight of the material into an electrical signal and transmits it to the control system. The control system compares the weight of the material with the preset target in real time according to these feedback information. If the weight of the material has not yet reached the target value, the control system will instruct the vibrating feeder assembly to continue conveying the material until the desired weight is reached.
[0060] After the conveyed material reaches the target weight, the weighing module 202 will again weigh the material in the open container 203 to confirm whether the target weight has been reached. If the target weight has been approached or achieved, the feedback signal will instruct the vibrating feeder assembly 1 to stop feeding, at which time the rotary drive mechanism 201 starts to work, driving the open container 203 to rotate at a set angle and dump the material in the open container 203. After the material is dumped, the open container 203 will be reset for the next round of material receiving.
[0061] The other is the cumulative weighing mode, that is, each time the material is weighed, it is dumped once. The system will continue to convey material to the open container 203 according to the difference between the current weight of the material and the target weight. Again, through this cumulative dumping problem, the total weight of the delivered material is ensured to be accurate.
[0062] Compared with traditional toner delivery devices, the device greatly improves the accuracy and stability of material conveying by combining vibrating feeding and precise weighing technology. Traditional toner delivery devices mostly rely on gravity feeding or screw conveying, which is difficult to accurately control the weight of the material and is easily affected by external environment, resulting in unstable conveying. The device can effectively eliminate these problems through real-time feedback control and precise weighing, providing a more stable and consistent material delivery solution.
[0063] In summary, the weight-based toner delivery device provided by this embodiment enables high-precision material conveying and metering, making it widely applicable to production processes that require precise dosing and control of material delivery. Through precise feedback control systems and optimized design solutions, this device has significant advantages in improving production efficiency, reducing material waste, and ensuring product quality consistency. Additionally, the device's adjustability and easy-to-clean design greatly enhance its adaptability and operational convenience in varying production environments.
