Description

Technical Field

[0001] This utility model relates to an automatic dispensing machine, and more particularly to an automatic dispensing machine for small granular powder crystalline seasonings. Background Technology

[0002] During cooking, the main pain points of using powdered seasoning containers are concentrated in the following three aspects:

[0003] I. The Dilemma of One-Handed Operation

[0004] For frequently used crystalline powder seasonings such as salt, sugar, and chicken bouillon, traditional containers often require two-handed operation: simultaneously grasping the container, unscrewing the lid, and pouring the contents. This not only reduces cooking efficiency but also increases the risk of container slippage and breakage.

[0005] II. The Challenge of Precise Quantity Control

[0006] Current containers lack effective quantitative control devices, which can easily lead to uncontrolled dosage when pouring, potentially wasting seasonings and affecting the consistency of dish flavor.

[0007] III. Defects in Sealing and Moisture Prevention

[0008] During frequent opening and closing, most containers are difficult to keep sealed for a long time. Especially in the high humidity of the kitchen environment, condiments are prone to moisture absorption and clumping, which seriously affects the quality of food.

[0009] Currently, the automated production process of powder crystals on the market uses screw conveyors for feeding, achieving precise quantity control and automatic discharge.

[0010] These problems collectively lead to multiple drawbacks in the condiment dispensing process, including low efficiency, safety hazards, and material loss, which urgently need to be addressed through optimized container dispensing design. Utility Model Content

[0011] To address the shortcomings of the aforementioned technologies, this invention provides an automatic dispensing machine for small-particle, powder, and crystalline seasonings.

[0012] To solve the above technical problems, the technical solution adopted by this utility model is: an automatic dispensing machine for small granular powder crystalline seasonings, comprising:

[0013] The support unit is supported by a support frame to form a support space that allows material to be retrieved from above;

[0014] The feeding unit connects the lower support space and the upper feeding container through a storage container mounted on the support frame. An execution chamber is provided on the side of the feeding container. A self-rebound slider assembly is arranged longitudinally in the execution chamber. The self-rebound slider assembly drives a second motor to move backward through a cam transmission mechanism connected to a first motor. The second motor is connected to and drives a spiral push rod to extend downward to the feeding container, forming an axial spiral opening and closing of the connection between the feeding container and the support space.

[0015] The control unit is equipped with a through-beam sensor inside the support frame to monitor the material being picked up in the support space, and a control board inside the support frame to receive the monitoring signals from the through-beam sensor. The control board is electrically connected to motor number one and motor number two.

[0016] Energy storage unit, an energy storage battery electrically connected to the control board.

[0017] Furthermore, the support space of the support frame is formed within the U-shaped space enclosed by the upper support frame, the upright plate, and the lower support frame; the through-beam sensor includes a transmitter and a receiver, with the transmitter mounted on the upper support frame and the receiver mounted on the lower support frame at a position opposite to the transmitter.

[0018] Furthermore, the lower opening of the storage container is snapped or threaded onto the upper support frame, which has a discharge channel running from top to bottom. The discharge channel connects upward to the lower opening of the storage container, and the upper opening of the storage container connects upward to the feed container.

[0019] Furthermore, the rebound slider assembly includes at least two vertically arranged sliders, the bottom end of each slider is fixedly connected to the base plate inside the execution chamber, a slider is slidably arranged on all sliders, the top end of all sliders is connected to a top plate, and a spring is fitted on the outside of any slider to make the slider rebound, the spring abutting between the slider and the base plate.

[0020] Furthermore, the No. 1 motor is mounted horizontally on the top plate via the No. 1 bracket. The cam of the cam transmission mechanism is mounted on the shaft of the No. 1 motor. The driven wheel of the cam transmission mechanism is rotatably mounted on the No. 2 bracket connected to the slider. When the cam rotates, the driven wheel is close to the edge of the cam.

[0021] Furthermore, the second motor is connected to the slider, and the shaft of the second motor is equipped with the rod body of the spiral pusher. The lower part of the rod body has a spiral part, which is set in the discharge channel. The lower end of the threaded part is connected to a piston that seals the lower opening of the discharge channel.

[0022] Furthermore, the control unit also includes a limit switch assembly located in the execution chamber. The limit switch assembly includes a first limit switch and a second limit switch, which are set at high and low positions in the execution chamber via a third bracket. Both the first and second limit switches are electrically connected to the control board, and a slider is provided between the first and second limit switches.

[0023] This utility model discloses an automatic dispensing machine for small-particle, powdered, and crystalline seasonings. Using a through-beam sensor to detect the position of the receiving container, the user only needs to place the container with one hand to trigger dispensing, eliminating the need for two-handed operation of opening the lid and tilting the container, thus solving the problem of one-handed operation. The system automatically completes the opening and closing of the dispensing port and the pushing action, completely eliminating the steps of gripping and screwing on the traditional container, improving cooking efficiency and reducing the risk of slippage. A dual-motor drives the spiral pusher, and the pushing time is controlled by a preset time or continuous mode to ensure consistent dispensing dosage each time, avoiding waste and taste deviation. Dual-motor collaboration (valve opening before pushing) ensures that the dispensing port is fully open before pushing, and combined with limit switch feedback, further ensures dosage accuracy. After dispensing, the self-rebound slider assembly automatically resets via a spring, driving the piston to seal the dispensing channel and reduce the intrusion of external moisture.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] An automatic dispensing machine for small-particle, powdery, and crystalline seasonings includes a support unit, a feeding unit, a control unit, and an energy storage unit.

[0033] Figure 1 The support unit shown is supported by the support frame 100 to form a support space that allows material to be picked up from above. The support space of the support frame 100 is formed within a U-shaped space enclosed by the upper support frame 101, the upright plate 102, and the lower support frame 103, ensuring the stability of the overall structure of the equipment. The U-shaped support space forms an open material picking area, allowing users to easily place receiving containers from above. The through-beam sensor 310 includes a transmitter 312 and a receiver 311. The receiver 311 is mounted on the upper support frame 101, and the transmitter 312 is mounted on the lower support frame 103 at a position opposite to the receiver 311. The through-beam sensor is installed across the layers at both ends of the U-shaped space. It detects whether a receiving tool is placed below the discharge port through infrared signals, realizing contactless triggering of the discharge action and avoiding misoperation.

[0034] Figure 2The feeding unit shown connects the lower support space and the upper feeding container 210 via a storage container 200 mounted on the support frame 100. The lower opening of the storage container 200 is snap-fitted or threaded onto the upper support frame 101. The storage container is detachable for easy cleaning or replacement of different materials. The upper support frame 101 has a discharge channel that runs from top to bottom and connects upward to the lower opening of the storage container. This forms a layered, through-type storage structure. The upper feeding container allows for rapid replenishment and forms a vertical material flow channel with the storage container, ensuring accurate delivery of seasonings from top to bottom and preventing lateral spillage. The upper opening of the storage container connects upward to the feeding container 210. An execution chamber 220 is provided on the side of the feed container 210. A self-returning slider assembly is longitudinally arranged within the execution chamber 220. The self-returning slider assembly is longitudinally driven by a cam transmission mechanism connected to a first motor 230, which in turn drives a second motor 240 to move backward. The second motor 240 is connected to and drives a spiral pusher 250 to extend downward into the feed container 210, forming an axial spiral opening and closing mechanism between the feed container 210 and the support space. Specifically, Figure 3 and Figure 4 The shown spring-loaded slider assembly includes at least two vertically arranged sliders 261. The bottom end of each slider is fixedly connected to a base plate 262 inside the execution chamber. A slider 263 is slidably mounted on all sliders 261. A top plate 264 is connected to the top end of all sliders 261. A spring 265 is fitted around any slider 261 to cause the slider 263 to spring back. The spring 265 abuts between the slider 263 and the base plate 262. A first motor 230 is horizontally mounted on the top plate 264 via a first bracket 270. A cam 281 of a cam transmission mechanism is mounted on the shaft of the first motor 230. The driven wheel 282 of the cam transmission mechanism is rotatably mounted on a second bracket 283 connected to the slider 263. When the cam 281 rotates, the driven wheel 282 is close to the edge of the cam 281. Figure 5 As shown, motor 240 is connected to slider 263. The shaft of motor 240 is fitted with the rod body 251 of screw pusher 250. The lower part of rod body 251 has a screw section 252, which is located within the discharge channel. The lower end of the screw section is connected to a piston 253 that seals the lower opening of the discharge channel. The above employs dual-motor coordinated control. Motor 1 converts rotational motion into longitudinal displacement of the slider via a cam and driven wheel, driving the screw pusher to axially open and close the discharge port. Motor 2 directly drives the screw section to rotate and push material. The two work together to achieve a "valve open first, then push" sequence, ensuring both the sealing of the discharge port and improving quantity control accuracy through screw quantitative extrusion. The slider assembly uses a slide rod and spring to form an elastic reset system. After pushing material, the spring automatically rebounds, causing the piston to close the discharge channel, preventing moisture intrusion. The cam edge contour is designed to fit snugly against the driven wheel, ensuring stable and controllable slider displacement and preventing mechanical jamming.

[0035] Figure 6 As shown, the control unit includes a through-beam sensor installed within the support frame 100 to monitor the material handling position in the support space, and a control board 300 installed within the support frame 100 to receive monitoring signals from the through-beam sensor. The control board 300 is electrically connected to motor 230 and motor 240. The control unit also includes a limit switch group located within the execution chamber 220. The limit switch group includes a first limit switch 321 and a second limit switch 322 installed at high and low positions within the execution chamber via a third bracket 323. Both the first limit switch 321 and the second limit switch 322 are electrically connected to the control board 300, and a slider 263 is provided between the first limit switch 321 and the second limit switch 322. The control unit uses a through-beam sensor 310 as its core detection module. It forms a longitudinal infrared light path through the transmitter 312 of the upper support frame 101 and the receiver 311 of the lower support frame 103 to monitor in real time whether a receiving container is placed below the discharge port. After receiving the sensor signal, the control board 300 combines the feedback of the displacement status of the slider 263 from the limit switch group (limit switch 321 and limit switch 322) to coordinate the start and stop sequence of motor 230 and motor 240.

[0036] The control process is as follows:

[0037] Detection triggering stage – When the receiving container (such as a spatula, seasoning bowl, etc.) enters below the discharge port, it blocks the infrared light path of the through-beam sensor 310, interrupting the signal between the transmitter 312 and the receiver 311, and immediately sending a trigger signal to the control board 300. The control board 300 eliminates momentary interference (such as a hand briefly passing by) through a delay judgment; Discharge preparation stage – The control board 300 starts the first motor 230, driving the cam 281 to rotate. The cam 281 pushes the driven wheel 282, causing the slider 263 to move down along the slide rod 261. The spiral pusher rod 250 moves down accordingly, and the piston 253 leaves the discharge channel to form a gap; When the slider 263 triggers the low-position second limit... When switch 322 is activated, control board 300 confirms that the discharge port is fully open. In the quantitative discharge stage, control board 300 immediately starts motor 240, driving the auger 252 to rotate. In quantitative mode, the feeding time is controlled according to a preset time. In continuous mode, feeding continues until sensor 310 detects the removal of the obstruction. In the closing and reset stage, after discharge is complete, control board 300 first stops motor 240, then rotates motor 230. Cam 281 returns to its original position, causing slider 263 to move upward under the action of spring 265, and piston 253 re-seals the discharge channel. When slider 263 triggers high-position limit switch 321, the system completely stops. Furthermore, to increase human-machine interaction, control panels can be added in other embodiments to control the above triggering process. The working principle can use existing electrical control principles, which will not be elaborated here.

[0038] The energy storage unit is a battery 400 electrically connected to the control board 300. The installation location of the battery 400 is not limited. In this embodiment, the battery 400 is located inside the support frame 100 and connected to the upper support frame 101. A rechargeable lithium battery pack 400 is used as the energy storage core. It is connected to the power input port of the control board by direct soldering of the positive and negative terminals or by connectors. A voltage conversion circuit (such as a DC-DC step-down module) is set at the input of the control board to stably convert the battery voltage (typical value 3.7V-12V) to a 3.3V / 5V system operating voltage. The control board 300 integrates a charge / discharge management chip, implemented through a Type-C interface. The main controller of the control board 300 can use a low-power MCU (such as the STM32F030 series), an onboard signal conditioning circuit (infrared sensor signal amplification and filtering), and a dual H-bridge driver chip (such as L298N) to control the forward and reverse rotation of the motor.
