Description

Technical Field

[0001] This utility model relates to the field of toner production technology, specifically to an auxiliary batching device. Background Technology

[0002] In the production process of printer toner, the formulation of additives is one of the key steps. These additives are usually made by mixing various powder raw materials in a specific ratio, and the precision of their formulation directly affects the performance and quality stability of the final toner product.

[0003] Currently, the commonly used preparation process requires operators to equip each type of powder material with a separate container and dispensing scoop, adding them one by one during weighing. This method effectively avoids cross-contamination between different materials, ensures weighing accuracy, and is beneficial for product quality control. However, this method requires a large number of specialized tools (containers and dispensing scoops), and the operation steps are cumbersome and time-consuming, resulting in low overall production efficiency, especially in multi-batch, small-volume production scenarios.

[0004] To improve efficiency, another approach is to add all materials sequentially to the same container for weighing. This method reduces the number of tools used, simplifies the operation process, and significantly improves work efficiency. However, if an excessive amount of a certain material is added, it becomes difficult to separate it from the mixture, often resulting in the disposal of the entire batch, causing waste and affecting production schedules, with an extremely low tolerance for error.

[0005] Therefore, there is a contradiction between weighing accuracy and production efficiency in existing technologies, and there is an urgent need for an improved solution that can both ensure accurate batching and prevent cross-contamination, as well as improve operational efficiency and reduce resource consumption. Utility Model Content

[0006] Therefore, this utility model provides an auxiliary batching device to solve the problems of low efficiency, excessive tool usage, and low fault tolerance encountered in the batching process.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An auxiliary feeding device includes a support unit and a tilting loading unit. The support unit includes a support cylinder and a support mechanism disposed outside the support cylinder. The cylinder wall of the support cylinder has two spaced-apart rotating holes, which are located above the support mechanism and are coaxial. The tilting loading unit includes a rotating shaft and a loading tray. The two ends of the rotating shaft are rotatably mounted in the two rotating holes, and the loading tray is fixed to a section of the rotating shaft located inside the support cylinder. The central axis of the loading tray is perpendicular to the axis of the rotating shaft.

[0009] Furthermore, the support cylinder is a cylindrical cylinder, the material tray is a disc, and the outer diameter of the disc is smaller than the inner diameter of the cylindrical cylinder.

[0010] Furthermore, the support mechanism is a support ring plate that protrudes radially outward along the support cylinder.

[0011] Furthermore, the flipping loading unit also includes a rotating handle, which includes a rocker arm and a crank handle. One end of the rocker arm is perpendicularly connected to one end of the rotating shaft, and the other end of the rocker arm is perpendicularly connected to one end of the crank handle. The axis of the crank handle is parallel to the axis of the rotating shaft.

[0012] Furthermore, the rotating shaft, rocker arm, and crank handle are integrally bent and formed, and the connection between the rotating shaft and the rocker arm, as well as the connection between the rocker arm and the crank handle, are provided with rounded corners.

[0013] Furthermore, the auxiliary dispensing device also includes an elastic locking piece, which is disposed above the rotating hole near the rotating handle. The elastic locking piece includes a fixing part, a limiting part, a locking part, and a sliding part. The fixing part is fixed to the outside of the support cylinder. The first end of the limiting part is connected to the fixing part, and the second end of the limiting part extends away from the support cylinder. The first end of the locking part is connected to the second end of the limiting part, and the second end of the locking part extends towards the support cylinder. The distance between the second end of the locking part and the support cylinder is less than the diameter of the rocker arm. The first end of the sliding part is connected to the second end of the locking part, and the second end of the sliding part extends away from the support cylinder. The distance between the second end of the sliding part and the support cylinder is greater than the diameter of the rocker arm.

[0014] Furthermore, the auxiliary ingredient dispensing device is made of stainless steel.

[0015] Furthermore, the rotating shaft and the material tray are welded and fixed together.

[0016] Furthermore, the fixing part, limiting part, locking part and sliding part of the elastic locking piece are integrally formed, and the fixing part is welded and fixed to the support cylinder.

[0017] Furthermore, the edge of the material tray is provided with an upwardly protruding flange.

[0018] The auxiliary dispensing device of this utility model addresses the problem of "difficulty in balancing weighing accuracy and production efficiency" in the preparation of printer toner additives. Through structural design, it achieves synergistic optimization of function and efficiency, with the following specific advantages:

[0019] 1. Easy to operate and greatly improves production efficiency: Various materials are continuously loaded into the loading tray, eliminating the need for separate containers for each material. Multiple materials can be weighed and added sequentially, simplifying tool switching and operation processes, reducing tool preparation and material transfer time, solving the problems of cumbersome and time-consuming traditional processes, and significantly improving the material dispensing efficiency per unit time.

[0020] 2. Precise quantity control to ensure ingredient purity: The material is carried by a flip-over tray, and the operation logic of "weighing and then flipping to unload" is used. The weight of the material is monitored in real time by an electronic scale to ensure that each raw material is added in a specific proportion. This meets the stringent requirements of toner additives for formulation accuracy and ensures the stability of the final product performance.

[0021] 3. High tolerance for error and reduced resource waste: Weighing is done by an electronic scale. If the weight is too low, more material can be added to the loading tray. If the weight is too high, a portion of the raw material in the loading tray can be retrieved using a dispensing scoop. This allows for precise control of the material weight and eliminates the need to discard the mixed material in the dispensing container, effectively preventing the waste of the entire batch of materials.

[0022] 4. Good operability and strong adaptability: The elastic locking plate achieves stable locking of the material tray in a horizontal state, and the raised edge design prevents powder from spilling; the stainless steel material has both corrosion resistance and easy cleaning properties, avoiding material residue or equipment corrosion; it can be flexibly adapted to different ingredients and has strong versatility.

[0023] 5. Simple structure and low cost: The overall structure is compact, with no complex and precision parts. It adopts mature processes such as welding and integral bending, resulting in low manufacturing costs. It reduces the number of special containers used, lowers tool procurement and maintenance costs, and reduces material waste and loss, thus balancing economy and practicality.

[0037] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] like Figure 1-9 As shown, this embodiment provides an auxiliary feeding device, including a support unit 1 and a tilting loading unit 2. The support unit 1 includes a support cylinder 11 and a support mechanism disposed outside the support cylinder 11. The cylinder wall of the support cylinder 11 is provided with two spaced rotating holes 111, which are located above the support mechanism and are coaxial. The tilting loading unit 2 includes a rotating shaft 21 and a loading tray 22. The two ends of the rotating shaft 21 are rotatably installed in the two rotating holes 111, and the loading tray 22 is fixed on the shaft section of the rotating shaft 21 located inside the support cylinder 11. The central axis of the loading tray 22 is perpendicular to the axis of the rotating shaft 21.

[0039] The rotatable engagement between the rotating shaft 21 and the support cylinder 11 enables the switching between "horizontal weighing" and "tilting unloading," satisfying both the pollution prevention requirements for independent load-bearing of a single material and the ability to quickly transfer materials, thus structurally resolving the contradiction between "precision and efficiency." The rotating hole 111 is located above the support mechanism and is coaxial, ensuring smooth rotation of the rotating shaft 21, preventing tilting and jamming, and improving operational stability.

[0040] In this embodiment, the support cylinder 11 is a cylindrical cylinder, and the material tray 22 is a disc, the outer diameter of which is smaller than the inner diameter of the cylindrical cylinder.

[0041] The cylindrical tube has a smooth inner wall, which reduces powder residue and simplifies the processing. The disc-shaped material carrier 22 is adapted to the shape of the cylindrical tube. When rotating, the material carrier 22 will not interfere with the tube wall, ensuring the smoothness of the flipping action. The outer diameter of the material carrier 22 is smaller than the inner diameter of the cylindrical tube, which provides sufficient space for the flipping action and, through the enclosure effect of the support tube 11, prevents the material from scattering outside the device during the pouring process, improving the cleanliness of operation and reducing material loss.

[0042] In this embodiment, the support mechanism is a support ring plate 12 that protrudes radially outward along the support cylinder 11. Exemplarily, the support ring plate 12 is welded and fixed to the support cylinder 11. When the device is installed on the dispensing container 3, the lower end of the support cylinder 11 extends into the top opening of the dispensing container 3, and the lower side of the support ring plate 12 abuts against the top edge of the dispensing container 3.

[0043] The support ring plate 12 and the support cylinder 11 are highly integrated and the force is evenly distributed, which can provide a stable support foundation for the device, avoid the device from tilting and shaking during weighing and flipping, and ensure the weighing accuracy of the electronic scale 4. The support ring plate 12 makes it easy to set up the device above the batching container 3, improving the ease of use.

[0044] In this embodiment, the flipping loading unit 2 further includes a rotating handle 23, which includes a rocker arm 231 and a crank 232. One end of the rocker arm 231 is perpendicularly connected to one end of the rotating shaft 21, and the other end of the rocker arm 231 is perpendicularly connected to one end of the crank 232. The axis of the crank 232 is parallel to the axis of the rotating shaft 21.

[0045] The design of the rocker arm 231 being perpendicular to the rotating shaft 21 and the crank handle 232 being parallel to the rotating shaft 21 makes it easier for the operator to exert force when rotating; the vertical connection design of the rocker arm 231 ensures that the rotational force is directly transmitted to the rotating shaft 21, realizing precise speed control and rotation of the material tray 22.

[0046] In this embodiment, the rotating shaft 21, rocker arm 231 and crank handle are integrally bent and formed, and the connection between the rotating shaft 21 and the rocker arm 231 and the connection between the rocker arm 231 and the crank handle are provided with rounded corner transitions.

[0047] The one-piece molding structure has no splicing gaps, resulting in higher mechanical strength. It avoids breakage or loosening at the joints due to long-term rotation, extending the service life of the device and making it suitable for high-frequency industrial applications. The rounded corner design eliminates sharp edges, preventing operator scratches and reducing powder residue at the corners, while also improving processability and structural aesthetics.

[0048] In this embodiment, the auxiliary dispensing device further includes an elastic locking piece 13. The elastic locking piece 13 is disposed above the rotating hole 111 near the rotating handle 23. The elastic locking piece 13 includes a fixing part 131, a limiting part 132, a locking part 133, and a sliding part 134. The fixing part 131 is fixed to the outside of the support cylinder 11. The first end of the limiting part 132 is connected to the fixing part 131. The second end of the limiting part 132 extends away from the support cylinder 11. The first end of the locking part 133 is connected to the second end of the limiting part 132. The second end of the locking part 133 extends towards the support cylinder 11. The distance between the second end of the locking part 133 and the support cylinder 11 is less than the diameter of the rocker arm 231. The first end of the sliding part 134 is connected to the second end of the locking part 133. The second end of the sliding part 134 extends away from the support cylinder 11. The distance between the second end of the sliding part 134 and the support cylinder 11 is greater than the diameter of the rocker arm 231.

[0049] When the material tray 22 is in a horizontal weighing state, the locking part 133 can lock the rocker arm 231 to achieve precise locking of the material tray 22, prevent it from rotating accidentally, ensure the stability of the weighing process, and avoid weight deviation caused by device shaking; the inclined structure of the sliding part 134 facilitates the smooth entry of the rocker arm 231 into the locking position, and the spacing design between the locking part 133 and the support cylinder 11 ensures the reliability of locking and can also be easily unlocked through elastic deformation without affecting the operation efficiency of flipping and unloading; the limiting part 132 can limit the maximum rotation stroke of the rocker arm 231 to avoid excessive flipping that could cause material spillage or structural damage.

[0050] In this embodiment, the auxiliary ingredient dispensing device is made of stainless steel.

[0051] Stainless steel has excellent corrosion resistance and wear resistance, and can be in contact with powder materials for a long time without rusting, avoiding material contamination of raw materials and ensuring the purity of additives. The smooth surface of stainless steel does not easily leave powder residue, making it easy to clean later and reducing the risk of cross-contamination caused by material residue. At the same time, it improves the durability of the equipment and reduces maintenance costs.

[0052] In this embodiment, the rotating shaft 21 and the material tray 22 are welded and fixed.

[0053] The welded and fixed structure has high strength, preventing the material tray 22 from loosening and falling off due to long-term rotation, and ensuring the stability of use in industrial scenarios.

[0054] In this embodiment, the fixing part 131, the limiting part 132, the locking part 133 and the sliding part 134 of the elastic locking piece 13 are integrally formed, and the fixing part 131 is welded and fixed to the support cylinder 11.

[0055] The one-piece molded structure has no splicing gaps, resulting in higher mechanical strength. It avoids breakage or loosening at the connection points due to long-term rotation, extending the service life of the device and making it suitable for high-frequency industrial applications. It ensures the clamping force of the locking part 133, preventing elastic failure due to the splicing structure and ensuring the reliability of the locking function. The fixing part 131 is welded and fixed to the support cylinder 11 to prevent the elastic locking piece 13 from falling off during long-term use and improve the overall stability of the device structure.

[0056] In this embodiment, the edge of the material tray 22 is provided with an upwardly protruding flange 221.

[0057] The raised edge 221 can effectively prevent powder materials from spilling from the edge during horizontal weighing, especially suitable for powder raw materials with high flowability; at the same time, it can help operators control the amount of material added, further improve the accuracy of batching, and is suitable for the powder characteristics of toner additives.

[0058] How to use this device:

[0059] 1. First, place the auxiliary device above the mixing container 3 (the lower end of the support cylinder 11 is inserted into the top opening of the mixing container 3, and the lower side of the support ring plate 12 abuts against the edge of the top opening of the mixing container 3), and keep the loading tray 22 horizontally locked (the rocker arm 231 is inserted into the elastic locking piece 13).

[0060] 2. Place the auxiliary batching device and batching container 3 together on the electronic scale 4, and operate the electronic scale 4 to tare (weigh "zero").

[0061] 3. Place a powder material 5 on the loading tray 22 (use the dispensing spoon inside the container of the material to scoop the material onto the loading tray 22). After reaching the required weight (if the weight is insufficient, continue to add; if the weight is excessive, scoop it out), rotate the rotating shaft 21 by turning the handle to flip the loading tray 22 and unload the material into the mixing container 3.

[0062] 4. Restore the horizontal lock of the loading tray 22, and weigh and add the next type of material in the same way as above, until all types of materials have been added.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
