Description

Technical Field

[0001] This utility model relates to a measuring device, specifically a measuring device for packaged food. Background Technology

[0002] Packaging is an essential step in food processing. Currently, the common packaging method used by food processing companies involves workers opening the packaging bag, placing the food items into the bag one by one, and then placing the entire bag on a measuring instrument to measure and adjust it to the required value before sealing. This existing packaging measurement method is inefficient and has a large weighing error.

[0003] Chinese patent discloses an intelligent device for measuring food packaging (authorization announcement number CN 110550243A). This patented technology can solve the aforementioned problems. However, this patent cannot achieve multi-threaded simultaneous operation; it can only operate one at a time, resulting in low efficiency. Furthermore, the vertical feeding port and the delay between the feeding port and the weighing device cause inaccurate control of feeding precision due to excessively fast feeding speed. Therefore, those skilled in the art have provided a food packaging measuring device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a metering device for packaged food to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A food packaging metering device includes a device body, which includes an inlet, a rotating structure, and an outlet. The side plate of the inlet has a sliding groove that is slidably connected to a distributing plate. The distributing plate has a toothed groove containing a plate-moving gear. The plate-moving gear has a drive screw that is clearance-fitted with the side plate of the inlet. A feeding port is located on the right side of the distributing plate, and the extension line of the feeding port is tangent to the upper surface of the feeding platform. By pouring the food to be metered (hereinafter referred to as "the food to be measured") into the inlet, the food moves along the bottom plate of the inlet towards the distributing plate. The plate-moving gear at the bottom of the drive screw meshes with the toothed groove on the side of the distributing plate. By connecting a motor to the drive screw of the distributing plate, the distributing plate can move up and down relative to the bottom plate of the inlet.

[0007] Preferably: the material placement platform is fixedly connected to the structural layer, the lower part of the material placement platform is fixedly connected to the buffer layer, the lower part of the buffer layer is connected to the gravity sensor, the gravity sensor is fixedly connected to the structural layer, the lower part of the structural layer is fixedly connected to the connector, the lower part of the connector is fixedly connected to the compensating rod, the lower part of the compensating rod is fixedly connected to the counterweight, the connector is provided with a flipping groove and is rotatably connected to the connecting rod through a clearance fit between the flipping groove and the flipping part of the connecting rod, the connecting rod is arranged around the side of the rotating structure, the rotating structure includes a platform structural plate, the bottom of the platform structural plate is provided with a support column, the platform structural plate includes a main shaft and a secondary shaft inside, the upper part of the main shaft is fixedly connected to the main gear, the lower part of the main shaft is connected to the motor inside the support column, and the upper part of the secondary shaft is connected to the bearing and the secondary shaft through the bearing and the secondary shaft. The gears are fitted with a clearance, and the lower end of the secondary shaft is fixedly connected to the platform structure plate. Each secondary gear meshes with the main gear and the secondary gear meshes with the internal gear set inside the rotating structure. The food to be tested then slides down from the feeding port onto the feeding platform. The gravity sensor at the bottom of the feeding platform is pre-set with a threshold. When the pressure on the gravity sensor reaches the threshold, the motor is started to drive the main shaft to rotate and control the motor of the drive screw, so that the feeding plate closes downward to block the continued sliding of the food to be tested. The main shaft drives the upper main gear to rotate. The main gear meshes with the secondary gear, and the secondary gear meshes with the internal gear, so the torque provided by the motor is transferred to the rotating structure. The rotating structure drives the connecting rod to rotate counterclockwise, so that the feeding platform rotates counterclockwise to the next position, and can be measured again on the next feeding platform.

[0008] Preferably, the support column is provided with a feeding rod on the side other than the feeding port. The height of the feeding rod is located in the middle section of the compensating rod. A discharge port is provided below the feeding rod. When the feeding platform rotates to the vicinity of the feeding rod, the compensating rod will contact the feeding rod. Under the action of the flipping trough and the flipping component of the connecting rod, the feeding platform will flip, allowing the food that has been metered above to be poured into the discharge port. When the feeding rod and the counterweight are disengaged after rotating a certain angle, the feeding platform will return to horizontal under the action of the counterweight. The gravity sensor of the current feeding platform will send a signal to the motor that provides power to the main shaft and the drive screw to repeat the above operation. The device can be equipped with multiple sets of feeding port and discharge port devices to achieve a higher working utilization rate.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model can be equipped with multiple sets of inlet and outlet ports, and can simultaneously measure multiple sets of food.

[0011] 2. This utility model is almost fully automated, requiring no manual operation, and the algorithm is more accurate. The inclined discharge port and the material distribution partition reduce the delay between the discharge port and the weighing device, thereby improving the accuracy of the device.

The plate moving gear 216 is provided with a driving screw 212, which is clearance-fitted with the side plate of the inlet 2. The right side of the distributing plate 211 is provided with a feeding port 214, and the extension line of the feeding port 214 is tangent to the upper surface of the feeding platform 314.

[0021] The material placement platform 314 is fixedly connected to the structural layer 328. Below the material placement platform 314, a buffer layer 327 is fixedly connected to it. Below the buffer layer 327, a gravity sensor 326 is connected to it. The gravity sensor 326 is fixedly connected to the structural layer 328. Below the structural layer 328, a connector 323 is fixedly connected to it. Below the connector 323, a compensating rod 324 is fixedly connected to it. Below the compensating rod 324, a counterweight 325 is fixedly connected to it. The connector 323 has a tilting groove 322, which, through a clearance fit with the tilting part of the connecting rod 321, allows for rotatable connection with the connecting rod 321. The connecting rod 321 is arranged around the perimeter. On the side of the rotating structure 3, the rotating structure 3 includes a platform structure plate 316. The bottom of the platform structure plate 316 is provided with a support column 311. The platform structure plate 316 includes a main shaft 317 and a secondary shaft 318. The upper part of the main shaft 317 is fixedly connected to the main gear 319, and the lower part of the main shaft 317 is connected to the motor inside the support column 311. The upper part of the secondary shaft 318 is fitted with a secondary gear 320 through a bearing. The lower end of the secondary shaft 318 is fixedly connected to the platform structure plate 316.

The main shaft 317 drives the upper main gear 319 to rotate. The main gear 319 meshes with the auxiliary gear 320. 320 meshes with the internal gear 315, thus transferring the torque provided by the motor to the rotating structure 3. The rotating structure 3 drives the connecting rod 321 to rotate counterclockwise, causing the feeding platform 314 to rotate counterclockwise to the next position, allowing for measurement to be performed again on the next feeding platform 314. When the feeding platform 314 rotates to the vicinity of the unloading rod 312, the compensating rod 324 will contact the unloading rod 312, and under the action of the tilting groove 322 and the tilting component of the connecting rod 321, the feeding platform 314 will rotate counterclockwise to the next position. 4. Flip the device so that the measured food is poured into the discharge port 4. Then, rotate the feed rod 312 and the counterweight 325 at a certain angle to disengage them. Under the action of the counterweight 325, the feeding platform 314 returns to a horizontal position. The gravity sensor 326 of the current feeding platform 314 sends a signal to the motor that powers the main shaft 317 and the drive screw 212 to repeat the above operation. The device can be equipped with multiple sets of feed ports 2 and discharge ports 4 to achieve a higher utilization rate.
