Description

Technical Field

[0001] The invention relates to the technical field of food packaging, in particular to a method for packaging high-fat granular food. Background Art

[0002] Most of the existing food packaging is for packaging larger foods, bulk foods or foods that have been packaged in small packages, but the packaging of granular foods is relatively backward. Granular foods are fragile (resulting in a decrease in the quality of granular foods) and are weighed by counting, which leads to inconsistent weighing. In addition, if manual weighing is used, it is time-consuming and labor-intensive, and the packaging efficiency is very low, and errors are prone to occur. In addition, when packaging high-fat granular foods, if multiple foods are placed on a conveyor line for transportation, they are prone to adhesion, affecting the normal packaging and processing of high-fat granular foods.

[0003] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a method for packaging high-fat granular foods to solve the following problems: (1) high-fat granular foods are prone to adhesion during transportation, affecting normal packaging processing; (2) manual weighing is used when packaging high-fat granular foods, which is time-consuming and labor-intensive, and has low packaging efficiency.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for packaging high-fat granular food, comprising the following steps:

[0008] Step 1: Load the high-fat granular food into the discharge mechanism, and the high-fat granular food in the discharge mechanism is sequentially delivered to the inside of the feeding mechanism on the conveying frame through the discharge rack;

[0009] Step 2: The high-fat granular food falls into the feeding frame in the feeding mechanism, and the weight of the high-fat granular food in the feeding frame is weighed by a weighing sensor arranged at the bottom of the fixed frame. When the weighed value is lower or higher than the standard value preset in the weighing sensor, the signal is transmitted to the sorting mechanism;

[0010] Step 3: Use the sorting mechanism to take out the food that does not meet the weight standard from the feeding frame. After the conveyor line brings the feeding frame to the bottom of the sorting mechanism, the servo electric cylinder pushes the mounting frame downward until the two picking frames enter the feeding frame. At this time, the two electric push rods push the two picking frames to move relative to each other, and the high-fat granular food in the feeding frame is clamped. Then the mounting frame is reset, and the second rotating frame is driven by the servo motor to rotate to one side of the movable receiving frame, so that the clamped high-fat granular food falls into the collection frame along the movable receiving frame;

[0011] Step 4: The driving motor drives the conveyor line to transmit at a uniform speed in the conveyor frame, so that the high-fat granular food that has been weighed and sorted in the feeding frame enters the automatic packaging machine from the feed hopper, and the automatic packaging machine is used to complete the packaging process of the high-fat granular food.

[0012] Preferably, the working method of the discharge mechanism in step 1 is as follows:

[0013] The first rotating frame drives the discharge rack to rotate. When a discharge hopper on the discharge rack rotates to the bottom of the drop tube, the electric motor drives the baffle plate to rotate in the drop tube, controlling the high-fat granular food in the discharge cavity to fall from the drop tube into the discharge hopper. Then the discharge rack continues to rotate, and the discharge hopper with high-fat granular food inside rotates to one side of the drop rack. The high-fat granular food rolls from the discharge hopper to the drop rack, and the high-fat granular food in the drop rack rolls into the feeding mechanism.

[0014] Preferably, the feeding mechanism in step 2 includes a conveying frame, a conveying line, a driving motor, a fixed frame, a feeding frame and a weighing sensor, the conveying frame is arranged on the left side of the discharge box, and the conveying line is arranged inside the conveying frame, the conveying line is driven by the driving motor, and a plurality of fixed frames are equidistantly arranged on the surface of the conveying line, the feeding frame is movably arranged inside the fixed frame through a limiting assembly, and a weighing sensor is arranged at the bottom of the fixed frame.

[0015] Preferably, the method of using the limit assembly is as follows:

[0016] The limit blocks on both sides of the feeding frame are slid into the two limit grooves, and the surfaces of the two sliding rods are respectively inserted into the inside of the two limit blocks, and the two limit plates are pulled out from the movable grooves, and the limit blocks are limited in the limit grooves by the two limit plates. After the high-fat granular food is put into the feeding frame, the feeding frame applies pressure to the weighing sensor at the bottom under the weight of the high-fat granular food, and the weight of the high-fat granular food in the feeding frame is weighed by the weighing sensor.

[0017] Preferably, the sorting mechanism in step three includes a sorting frame, a collecting frame, a movable material receiving frame, an electric push rod 1, a servo cylinder, a mounting frame, a second rotating frame, a servo motor, a fixed frame, a material picking frame and an electric push rod 2, the sorting frame is arranged on one side of the top of the conveying frame, and a collecting frame is arranged on one side of the sorting frame, a mounting frame is movably arranged inside the sorting frame, and a second rotating frame is rotatably arranged inside the mounting frame, a servo motor is arranged on one side inside the mounting frame, and one end of the servo motor output shaft is fixedly connected to one side of the second rotating frame, a fixed frame is arranged at the bottom of the second rotating frame, and two material picking frames are symmetrically and movably arranged at the bottom of the fixed frame, and an electric push rod 2 is arranged on one side of the two material picking frames, a movable material receiving frame is slidably arranged inside the collecting frame, and an electric push rod 1 is arranged at the bottom of the movable material receiving frame, a servo cylinder is arranged on the top of the sorting frame, and one end of the servo cylinder driving shaft is fixedly connected to the top of the mounting frame.

[0018] Preferably, in step three, the servo motor drives the second rotating frame to rotate 90° toward one side of the movable material receiving rack, and then the electric push rod pushes the right side of the movable material receiving rack to the bottom of the material taking rack. At this time, the two material taking racks are separated to allow the granular food to fall.

[0019] (III) Beneficial effects

[0020] The present invention provides a method for packaging high-fat granular food. Compared with the prior art, it has the following beneficial effects:

[0021] By arranging a plurality of fixed frames on the conveyor line, and each fixed frame is provided with a feeding frame, the feeding frame is used to perform individual metering and conveying of high-fat granular foods, thereby solving the problem that the high-fat granular foods on the conveyor line are easy to stick together during the conveying process. After the high-fat granular foods enter the feeding frame, the weight of the high-fat granular foods in the feeding frame is weighed by a weighing sensor arranged at the bottom of the fixed frame. When the weighed value is lower than or higher than the standard value preset in the weighing sensor, the signal is transmitted to the sorting mechanism, and the food that does not meet the weight standard is taken out from the feeding frame by the sorting mechanism. The driving motor drives the conveyor line to perform uniform speed transmission in the conveying frame, and the high-fat granular foods in the feeding frame are fed into the packaging machine to complete the automatic packaging process. By arranging a weighing sensor at the bottom of the feeding frame, automatic weight data collection is performed during the conveying of the packaged food. There is no need for manual measurement and weighing, which reduces the intensity of manual labor and effectively improves the packaging efficiency of high-fat granular foods. In addition, foods that do not meet the packaging weight standards are automatically sorted and processed, avoiding invalid packaging of foods that do not meet the packaging standards, and ensuring the product quality of high-fat granular foods after packaging. By setting a sorting mechanism on the conveyor line, high-fat granular foods that do not meet the packaging standards are automatically sorted and processed. The entire processing process has a high degree of automation and does not require manual auxiliary operations. It not only improves the packaging efficiency of food, but also ensures the constant quality of food after packaging, avoiding the occurrence of empty packages and wrong packages. In addition, the limiting component is used to realize flexible disassembly and assembly between the feeding frame and the fixed frame. When cleaning the inside of the feeding frame, the feeding frame can be conveniently taken out of the fixed frame for cleaning, thereby ensuring the cleanliness of the transportation of high-fat granular foods.

When a discharge hopper on the discharge frame 105 rotates to the bottom of the drop tube 103, the electric motor drives the baffle plate 104 to rotate in the drop tube 103, and controls the high-fat granular food in the discharge chamber 102 to fall from the drop tube 103 to the discharge hopper. Then the discharge frame 105 continues to rotate, and the discharge hopper with high-fat granular food inside rotates to the side of the drop frame 107, and the high-fat granular food rolls from the discharge hopper to the drop frame 107, and the high-fat granular food in the drop frame 107 rolls into the feeding mechanism 200;

[0035] Step 2: The high-fat granular food falls into the feeding frame 205 in the feeding mechanism 200, and the weight of the high-fat granular food in the feeding frame 205 is weighed by the weighing sensor 206 provided at the bottom of the fixed frame 204. When the weighed value is lower or higher than the standard value preset in the weighing sensor 206, a signal is transmitted to the sorting mechanism 300;

[0036] Step 3: Use the sorting mechanism 300 to take out the food that does not meet the weight standard from the feeding frame 205. After the conveyor line 202 brings the feeding frame 205 to the bottom of the sorting mechanism 300, the servo electric cylinder 305 pushes the mounting frame 306 downward until the two material taking frames 310 enter the feeding frame 205. At this time, the two electric push rods 311 push the two material taking frames 310 to move relative to each other to clamp the high-fat granular food in the feeding frame 205, and then reset the mounting frame 306, and then drive the second rotating frame 307 to rotate 90° to one side of the movable receiving frame 303 through the servo motor 308, and then the electric push rod 1 304 pushes the right side of the movable receiving frame 303 to the bottom of the material taking frame 310, and the two material taking frames 310 separate, allowing the clamped high-fat granular food to fall into the collection frame 302 along the movable receiving frame 303;

[0037] Step 4: The driving motor 203 drives the conveyor line 202 to perform uniform transmission in the conveyor frame 201, so that the high-fat granular food that has been weighed and sorted in the feeding frame 205 enters the automatic packaging machine 400 from the feed hopper 401, and the automatic packaging machine 400 completes the packaging process of the high-fat granular food.

Then the feeding rack 105 continues to rotate. After the feeding hopper containing the high-fat granular food rotates to the side of the feeding rack 107, the high-fat granular food rolls from the feeding hopper to the feeding rack 107.
