Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] This embodiment provides a feeding device for a powder compression molding and packaging system, such as... Figures 1 to 3As shown, it includes a drive mechanism 1, a spreading mechanism 2, a material holding trough 3, and a material leveling mechanism 4; The drive mechanism 1 is connected to the spreading mechanism 2. The drive mechanism 1 is configured to drive the spreading mechanism 2 to move intermittently along the X and Y directions. The spreading mechanism 2 has a discharge port 231 and is configured to discharge the material intermittently from the discharge port 231. The material trough 3 is located below the discharge port 231. The material trough 3 has multiple spreading zones 31 for receiving the material discharged from the discharge port 231. Each spreading zone 31 is the same size and is evenly arranged. The material leveling mechanism 4 is connected to the material trough 3. The material leveling mechanism 4 is configured to spread the material falling into each spreading zone 31 to the surrounding area.

[0024] In this embodiment, the feeding device is used such that the driving mechanism 1 drives the spreading mechanism 2 to move intermittently along the X and Y directions, thereby enabling the discharge port 231 of the spreading mechanism 2 to be vertically aligned with each spreading area 31 in the material container 3. When the discharge port 231 is aligned with the spreading area 31, the spreading mechanism 2 discharges the material from the discharge port 231 to the corresponding spreading area 31. After spreading is complete, the spreading mechanism 2 stops spreading, and the driving mechanism 1 drives the spreading mechanism 2 to move along the X and Y directions to align with the next spreading area 31. When each spreading area 31 is evenly distributed with material, the equalizing mechanism 4 causes the material falling into each spreading area 31 to spread outwards, such as... Figure 4 As shown, this ensures that the material is evenly distributed within the trough.

[0025] In the above embodiment, after the driving mechanism 1 drives the spreading mechanism 2 to spread material to each spreading area 31, the material is evenly distributed in the material holding trough 3. Even if there are slight differences in the amount of material between each pile, the material can be spread to the surrounding area by the material equalization mechanism 4 to achieve the purpose of uniform spreading.

[0026] Therefore, the above embodiments effectively reduce the requirements for single-time material spreading accuracy by using the "step-by-step spreading + centralized uniform spreading" method. High uniformity is achieved through the "passive compensation uniform spreading" of the uniform spreading mechanism 4, ensuring product yield. This solves the problem of needing to strictly control influencing factors caused by the "single-time spreading" in traditional methods, and reduces the installation and debugging time of the device.

[0027] The aforementioned material may be, but is not limited to, resin powder. The aforementioned device enables the resin powder to be evenly spread in the material tank 3. After the resin material is melted, there is no obvious flow, which effectively improves the yield rate.

[0028] It should be noted that any structure capable of intermittently moving the spreading mechanism 2 along the X and Y directions can be the drive mechanism 1 mentioned in the above embodiments. For example, the drive mechanism 1 includes a dual-axis linear motor drive structure, which includes a first linear motor guide rail arranged along the X direction and a second linear motor guide rail connected to the first linear motor guide rail and arranged along the Y direction; or the drive mechanism 1 includes a multi-axis motion manipulator; or the drive mechanism 1 includes a first hydraulic cylinder that can extend and retract along the X direction and a second hydraulic cylinder connected to the first hydraulic cylinder that can extend and retract along the Y direction.

[0029] In alternative implementations, such as Figure 5 As shown, the drive mechanism 1 includes a first drive component 11 and a second drive component 12. The first drive component 11 is connected to the second drive component 12. The first drive component 11 is configured to drive the second drive component 12 to move along the X direction. The second drive component 12 is connected to the spreading mechanism 2. The second drive component 12 is configured to drive the spreading mechanism 2 to move along the Y direction.

[0030] The above-described implementation achieves X-axis driving and Y-axis driving respectively through the first driving component 11 and the second driving component 12, which makes the precision easier to control compared to using a robotic arm.

[0031] In alternative implementations, such as Figure 5 and Figure 6 As shown, the first drive assembly 11 includes a first housing 111, a first driver 112, a first screw 113, and a first sliding frame 114.

[0032] The first housing 111 serves as the basic support structure for the first drive assembly 11, possessing sufficient structural strength and rigidity to fix and support the remaining components. The first driver 112 is mounted on the first housing 111, and is preferably a servo motor or a stepper motor, possessing high-precision position control capabilities. Its output end is connected to the first screw 113 via a coupling, thereby transmitting rotational power to the first screw 113.

[0033] The first screw 113 is horizontally arranged along the X-axis and rotates with the first housing 111 through a bearing structure to ensure smooth operation and no axial movement during driven rotation. The first sliding bracket 114 is sleeved on the outer periphery of the first screw 113 and has an internal thread structure that matches the first screw 113, so that the first sliding bracket 114 and the first screw 113 form a helical pair.

[0034] In use, the first driver 112 drives the first screw 113 to rotate. Since the first sliding frame 114 is limited to sliding only in the X direction, linear motion is generated along the axial direction of the first screw 113, thereby realizing reciprocating motion in the X direction.

[0035] Specifically, a guide structure, such as a guide rail-slider pair or a guide rod-linear bearing combination, is provided between the first sliding frame 114 and the first housing 111 to ensure the straightness and stability of the first sliding frame 114 during movement and to prevent jamming or wear caused by off-center load or torque.

[0036] The second drive assembly 12 is fixedly connected to the first sliding frame 114 and moves synchronously along the X direction with the first sliding frame 114. Therefore, when the first drive 112 is working, it drives the first screw 113 to rotate, thereby driving the first sliding frame 114 and the second drive assembly 12 it carries to make precise intermittent reciprocating motion along the X direction, providing a reference platform for subsequent Y-direction motion.

[0037] In the above embodiments, the first drive component 11 achieves high-precision, stable and reliable linear motion control in the X direction through the screw and the first sliding frame 114. It has a compact structure and rapid response, and is suitable for application scenarios in powder compression molding and packaging systems where the repeatability of the feeding position and the positioning accuracy are high.

[0038] In alternative implementations, such as Figure 5 As shown, the second drive assembly 12 includes a second driver 121, a transmission structure 122, a second screw 123, and a second sliding frame 124.

[0039] The second driver 121 is fixedly connected to the first sliding frame 114 of the first drive assembly 11, and is preferably a stepper motor or a servo motor, which can provide stable and controllable power output. The transmission structure 122 is disposed between the second driver 121 and the second screw 123, and is used to transmit the rotational power of the second driver 121 to the second screw 123.

[0040] The aforementioned transmission structure 122 can change the direction of power transmission of the second driver 121, making the installation position of the second driver 121 more flexible, such as... Figure 5 As shown, the second driver 121 can be installed on the side of the second screw 123, and its power output shaft is set parallel to the second screw 123, thereby effectively reducing the length of the second drive assembly 12 along the extension direction of the second screw 123, making the structure of the second drive assembly 12 more compact.

[0041] The second screw 123 extends along the Y direction, and its two ends are rotatably mounted on the first sliding frame 114 via bearing seats, thereby achieving rotational engagement with the first drive assembly 11. The second sliding frame 124 is sleeved on the outer periphery of the second screw 123 and forms a threaded engagement with the second screw 123; at the same time, a guide structure is provided between the second sliding frame 124 and the first sliding frame 114, enabling it to slide linearly relative to the first sliding frame 114 along the Y direction, preventing rotational tendency caused by threaded transmission.

[0042] The aforementioned guide structure may include a slide rail disposed on the first slide frame 114 and a slider disposed on the second slide frame 124.

[0043] When in use, the second driver 121 is started, and its output shaft drives the second screw 123 to rotate through the transmission structure 122. Since the second sliding frame 124 is limited to move only in the Y direction, under the action of the screw, the second sliding frame 124 will reciprocate linearly along the axial direction of the second screw 123. Since the spreading mechanism 2 is fixedly installed on the second sliding frame 124, it moves synchronously with it, thereby realizing the precise positioning of the spreading mechanism 2 in the Y direction.

[0044] It should be noted that the second drive assembly 12 works in conjunction with the first drive assembly 11: the first drive assembly 11 drives the entire second drive assembly 12 and the material spreading mechanism 2 on it to move along the X direction, while the second drive assembly 12 independently controls the position adjustment of the material spreading mechanism 2 in the Y direction, thereby forming an intermittent motion path in a two-dimensional plane, so that the discharge port 231 of the material spreading mechanism 2 can be aligned with each material spreading area 31 in the material holding trough 3 in sequence.

[0045] The aforementioned second drive component 12 has a reasonable structural design, high transmission accuracy, and stable operation, which helps to improve the accuracy and repeatability of spatial positioning during the material feeding process, thereby ensuring the uniformity of material distribution and process stability.

[0046] In alternative implementations, such as Figure 5 As shown, the transmission structure 122 includes a first wheel body 1221, a transmission component 1222, and a second wheel body 1223. The first wheel body 1221 is connected to the second driver 121, the second wheel body 1223 is connected to the second screw 123, and the transmission component 1222 is connected between the first wheel body 1221 and the second wheel body 1223.

[0047] The first wheel body 1221 and the second wheel body 1223 mentioned above can be either a pulley or a sprocket. Correspondingly, the transmission component 1222 can be either a belt or a chain.

[0048] The aforementioned transmission structure 122 enables the transmission of power between the second driver 121 and the second screw 123, making the setting position of the second driver 121 more flexible.

[0049] In alternative implementations, such as Figure 7 As shown, the material spreading mechanism 2 includes a first vibrator 21, a hopper 22 and a guide rail 23. The first vibrator 21 is connected to the second drive component 12 in the drive mechanism 1. The guide rail 23 is connected to the first vibrator 21 and has a discharge port 231. The hopper 22 is connected to the guide rail 23 and the discharge end of the hopper 22 is connected to the guide rail 23.

[0050] When the drive mechanism 1 positions the spreading mechanism 2 above a target spreading area 31, the first vibrator 21 starts, and the vibration is transmitted to the lower area of ​​the guide rail 23 and the hopper 22, causing the powder material attached to the inner wall to detach from the sticky state. Under the combined action of gravity and vibration, the material slides orderly along the guide rail 23 toward the discharge port 231, so that a predetermined amount of material is discharged from the discharge port 231 and falls into the spreading area 31. Then the first vibrator 21 stops working, and the drive mechanism 1 drives the spreading mechanism 2 to move to the next spreading area 31 to repeat the operation. This cycle continues until all spreading areas 31 have completed the initial spreading.

[0051] The guide track 23 can be a slender channel structure arranged in the horizontal direction. The top of one end is connected to the unloading end of the hopper 22, and the bottom of the other end forms an unloading port 231.

[0052] In addition, the hopper 22 is used to store the powder material to be formed. Its overall shape is a cone or funnel, wider at the top and narrower at the bottom, to facilitate the smooth falling of the material under gravity and avoid bridging or blockage. The bottom of the hopper 22 is provided with a discharge port as its unloading end. This discharge end is fixedly connected to the feed end of the guide rail 23 and maintains fluid communication, so that the material in the hopper can enter the internal channel of the guide rail 23 through the discharge port.

[0053] like Figure 7 As shown, the first vibrator 21 is installed at the bottom of the guide rail 23. The first vibrator 21 can be an electromagnetic vibrator, an eccentric motor or other controllable vibration source, which can generate high-frequency micro-amplitude vibration during operation and transmit the vibration energy to the guide rail 23 and the hopper 22.

[0054] In an alternative embodiment, the first vibrator 21 and the guide rail 23 in the spreading mechanism 2 can be replaced by other material conveying structures with quantitative conveying and controllable intermittent discharge functions.

[0055] Specifically, in an alternative embodiment, the first vibrator 21 and the guide rail 23 are replaced by a screw feeder, which includes a drive motor, a rotating screw, and a feeding cylinder sleeved around the screw. One end of the feeding cylinder is connected to the discharge end of the hopper 22, and the other end has a discharge port 231. The drive motor is electrically connected to the controller 7 in the feeding device and is configured to start and stop according to a preset timing sequence, thereby controlling the rotation of the screw. When the drive mechanism 1 moves the entire screw feeder above the target spreading area 31, the controller 7 starts the drive motor, causing the screw to rotate and push the powder material from the hopper 22 forward along the feeding cylinder, and discharge it quantitatively from the discharge port 231. By adjusting the motor speed, running time, and screw pitch parameters, the amount of material discharged each time can be controlled. After the feeding at this position is completed, the motor stops working, and the drive mechanism 1 then drives the screw feeder to move to the next spreading area, repeating the feeding process.

[0056] In another alternative embodiment, the first vibrator 21 and the guide rail 23 are replaced by a belt conveyor, which includes a conveyor belt and a drive unit. The feed end of the conveyor belt is located below the hopper 22 to receive the material, and the discharge end may be equipped with a controllable baffle or gate structure to form an openable / closeable discharge port 231. Its working principle is similar to that of the above alternative embodiment, and will not be described in detail here for the sake of brevity.

[0057] Based on the above embodiments, a valve 5 is provided at the discharge port 231 to control the opening and closing state of the discharge port 231.

[0058] Valve 5 includes a valve body and a movable valve core. The valve body is fixedly connected to the guide rail 23 and arranged around the discharge port 231. The valve core can move linearly or rotary under the action of the drive element to block or release the discharge port 231. The drive element can be a pneumatic cylinder, electric push rod, servo motor or electromagnet, etc., which is electrically connected to the controller 7 and can accurately control the opening and closing timing of valve 5 according to the preset feeding cycle.

[0059] The design of valve 5 ensures good timing control and spatial positioning accuracy for material discharge, making it particularly suitable for powder compression molding processes that require intermittent, fixed-point, and quantitative material supply. Simultaneously, closing valve 5 during non-discharge stages effectively prevents residual material from accidentally falling due to vibration or gravity, ensuring clean and controllable material distribution within the material trough 3, and improving subsequent uniform material distribution and the consistency of the final product density.

[0060] In alternative implementations, such as Figure 8 As shown, the material container 3 is equipped with a weight sensor 6, which is used to detect the weight information of the material container 3. The weight sensor 6 and the valve 5 are both connected to the controller 7, which is used to control the opening and closing of the valve 5 according to the weight information.

[0061] The controller 7 can be a PLC (Programmable Logic Controller), a microcontroller system, or an industrial control computer. The controller 7 is configured to receive real-time weight signals from the weight sensor 6 and dynamically adjust the opening and closing state of the valve 5 based on the weight information.

[0062] Specifically, during the feeding process, the drive mechanism 1 drives the spreading mechanism 2 to intermittently discharge material into each spreading zone 31. Before each discharge, the controller 7 records the baseline weight of the current material trough 3. When discharging into a certain spreading zone 31, the material falls into the corresponding area through the discharge port 231. The weight sensor 6 continuously monitors the increase in total weight and feeds the data back to the controller 7. When the detected weight increase reaches the single target feeding amount, the controller 7 immediately outputs a shut-off command to the valve 5 to cut off the material flow and stop the discharge.

[0063] The above implementation method realizes closed-loop feeding control based on actual weight feedback, which makes the amount of material falling into each feeding zone 31 more accurate.

[0064] In an optional embodiment, a material level sensor is provided inside the hopper 22 to detect the material level information inside the hopper 22.

[0065] The aforementioned level sensor can be any of the capacitive, ultrasonic, photoelectric, or contact sensors, and the selection and configuration should be based on the physical characteristics of the powder material.

[0066] The level sensor can also be connected to the controller 7. The level sensor converts the detected level information into an electrical signal and transmits it to the controller 7. When the material in the hopper 22 is lower than the preset minimum level threshold, the level sensor sends a low level signal to the controller 7. In response to this signal, the controller 7 starts the feeding and replenishing device to replenish the powder material to the hopper 22. When the material rises to the preset maximum level threshold, the level sensor sends a high level signal, and the controller 7 controls the feeding device to stop feeding, thereby realizing automatic replenishment and dynamic balance of the material in the hopper 22.

[0067] In an optional embodiment, the material leveling mechanism 4 includes a second vibrator connected to the material trough 3.

[0068] The second vibrator is any one of an electromagnetic vibrator, an eccentric motor vibrator, or a piezoelectric vibrator, preferably an adjustable frequency and amplitude electromagnetic vibrator, so as to adjust the vibration parameters according to the physical characteristics of the material such as flowability, particle size distribution, and bulk density, and achieve the optimal material diffusion effect.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
