Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a packaging machine with a limiting structure. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. When different types of rice are packaged into small sealed bags, one type of rice needs to be packaged completely before the next type is packaged. After each type of rice is packaged, the packaging equipment must be stopped for cleaning, debugging, and other preparatory work before the next type of rice can be packaged. This causes the equipment to be in a downtime state for a long time, greatly reducing the effective operating time of the equipment and resulting in a significant reduction in overall production efficiency. When changing varieties, it is necessary to wait for all the packaging materials of the previous type of rice to be cleaned before the new rice can be supplied for packaging. 1. Disruptions in material supply may occur, making it impossible to achieve a continuous and stable production process; 2. Different varieties of rice have inconsistent weights. If only measuring cylinders are used for measurement, it is impossible to package the inconsistent weights of rice each time. More packaging bags of different sizes are needed to accommodate rice of different weights, or the packaging bags may break due to overweight, thus increasing the cost of packaging materials. Rice bags of uneven weight will affect transportation efficiency and increase transportation costs due to overweight or light loads. Overweight packages will exceed the carrying capacity of the transportation vehicle, resulting in the need for additional transportation trips or larger transportation vehicles, while light loads will waste transportation space. Utility Model Content

[0004] The purpose of this utility model is to provide a packing machine with a limiting structure to solve the problem in the background art where, when packing different varieties of rice, it is necessary to wait for all the packaging materials of the previous type of rice to be cleared before the new rice can be supplied for packaging, which can lead to interruptions in material supply. To achieve the above objective, this utility model provides the following technical solution: a packing machine with a limiting structure, including a storage box, wherein a shell is provided in front of the storage box;

[0005] An inclined plate is welded inside the storage box. A support leg is installed at the bottom of the storage box by screws. A slide rail is installed in front of the support leg by screws. A discharge port is installed in front of the storage box by screws. A limiting plate is attached to the inside of the discharge port.

[0006] A control panel is mounted on the front of the housing by screws, a tray is mounted on the bottom of the housing by screws, a slider is mounted on one side of the housing by screws, a threaded rod is welded above the slider, a retaining ring is threaded to the outer wall of the threaded rod, a fixing plate is mounted on the front of the housing by screws, a magnetic plate is magnetically connected to the top of the fixing plate, and the outer wall of the magnetic plate is embedded in the card plate.

[0007] More preferably, the magnetic absorbing sheet in the middle of the card plate is perpendicular to the magnetic absorbing sheet in the middle of the fixing plate.

[0008] More preferably, the external structural dimensions of the threaded screw are consistent with the internal structural dimensions of the retaining ring.

[0009] More preferably, the slider has an "H" shape and the slider forms a horizontal sliding structure through a slide rail.

[0010] More preferably, the external structural dimensions of the limiting plate are consistent with the internal structural dimensions of the slot of the discharge port.

[0011] More preferably, the interior of the storage box has several squares evenly distributed, and the storage box and the inclined plate are integrally connected, and the inclined plate has an inclination angle of 20 degrees.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 The present invention provides a technical solution: a packing machine with a limiting structure, including a storage box 1, and a shell 2 provided in front of the storage box 1;

[0023] An inclined plate 101 is welded inside the storage box 1. A support leg 103 is installed at the bottom of the storage box 1 by screws. A slide rail 102 is installed in front of the support leg 103 by screws. A discharge port 105 is installed in front of the storage box 1 by screws. A limiting plate 104 is attached to the inside of the discharge port 105.

[0024] A control panel 203 is mounted on the front of the housing 2 by screws. A tray 204 is mounted on the bottom of the housing 2 by screws. A slider 208 is mounted on one side of the housing 2 by screws. A threaded rod 206 is welded above the slider 208. A retaining ring 207 is threadedly connected to the outer wall of the threaded rod 206. A fixing plate 202 is mounted on the front of the housing 2 by screws. A magnetic suction piece 205 is magnetically connected to the top of the fixing plate 202. The outer wall of the magnetic suction piece 205 is embedded in the card plate 201.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the magnetic absorbing piece 205 in the middle of the card plate 201 and the magnetic absorbing piece 205 in the middle of the fixing plate 202 are perpendicularly distributed. After the packaging bag is placed inside the housing 2, the two sides of the opening of the packaging bag are attached to the fixing plate 202. At this time, the magnetic absorbing piece 205 in the card plate 201 and the magnetic absorbing piece 205 in the fixing plate 202 can attract and stick to each other due to their perpendicular distribution. The magnetic force is used to firmly fix the opening of the packaging bag. This design is simple, effective and easy to operate. It can achieve the fixing function without complex mechanical structure, and achieve the fixing of the two sides of the opening of the packaging bag. It ensures that the opening of the packaging bag remains stable during the process of putting rice into the packaging bag, and there will be no loosening or displacement, thus ensuring the accuracy of weighing and packaging.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the external structural dimensions of the threaded screw 206 are consistent with the internal structural dimensions of the fixing ring 207. After different varieties of rice are poured into the storage box 1, the slider 208 connected to the movable housing 2 is aligned with the discharge port 105. At this time, the fixing ring 207 is rotated to move on the threaded screw 206. Since the external structural dimensions of the threaded screw 206 are consistent with the internal structural dimensions of the fixing ring 207, the fixing ring 207 can fit tightly on the threaded screw 206 and be fixed by the friction of the threads. In this way, the housing 2 driven by the slider 208 cannot move, providing a stable foundation for subsequent weighing and packaging operations. The fixing ring 207 can rotate stably on the threaded screw 206, thereby fixing the slider 208 and the connected housing 2, preventing the housing 2 from moving accidentally during the weighing and packaging process, which would affect the accuracy and stability of the operation.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the slider 208 has an "H"-shaped external shape, and the slider 208 forms a horizontal sliding structure through the slide rail 102. Before weighing and packaging, the housing 2 needs to be moved to a suitable position. The "H"-shaped external shape of the slider 208 makes it more stable when sliding on the slide rail 102, and it is not easy to shake or deviate from the track. Through the horizontal sliding structure, the operator can easily move the housing 2 below the discharge port 105 of the storage box 1 to ensure that the rice can fall accurately into the packaging bag. This design makes the operation more flexible and convenient, improves work efficiency, and makes it easy to adjust the position of the housing 2 so that it can be accurately aligned with the discharge port 105 to ensure that the rice can smoothly enter the packaging bag. At the same time, the "H"-shaped slider 208 design can increase the contact area with the slide rail 102 and improve the stability of sliding.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the external structural dimensions of the limiting plate 104 are consistent with the internal structural dimensions of the slot in the outlet 105. When preparing for weighing and packaging operations, the limiting plate 104 is removed. Since the external structural dimensions of the limiting plate 104 are consistent with the internal structural dimensions of the slot in the outlet 105, the limiting plate 104 can fit tightly with the outlet 105, thus providing a seal. When feeding is required, the limiting plate 104 is removed, and the rice in the storage box 1, guided by the inclined plate 101, smoothly enters the packaging bag through the outlet 105. During the weighing process, if the required weight is reached, the limiting plate 104 can be inserted in time to prevent the rice from continuing to flow out, ensuring the accuracy of weighing and controlling the amount of rice discharged. When feeding is required, the limiting plate 104 is removed so that the rice in the storage box 1 can smoothly enter the packaging bag. When feeding is not required, the limiting plate 104 is inserted to prevent the rice from continuing to flow out, ensuring the accuracy of weighing.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the storage box 1 has several squares evenly distributed inside, and the storage box 1 and the inclined plate 101 are integrally connected. The inclined plate 101 has a 20-degree tilt angle. The several squares inside the storage box 1 can store different varieties of rice separately, making it convenient for operators to select different types of rice for weighing and packaging as needed. When discharge is required, due to the 20-degree tilt angle of the inclined plate 101, the rice will slide down the inclined plate 101 under the action of gravity and flow smoothly to the discharge port 105. The integral connection design can ensure the stability of the inclined plate 101 and prevent loosening or displacement during the flow of rice. The internal square design can facilitate the classification and storage of different varieties of rice and prevent different varieties of rice from mixing. The design of the inclined plate 101 can guide the rice to flow smoothly to the discharge port 105, improving the discharge efficiency.

[0030] In this embodiment, as Figure 3 and Figure 4As shown, the control panel 203 and the center gravity sensor of the tray 204 are connected by a cable. When rice enters the packaging bag through the discharge port 105 and falls onto the tray 204, the gravity sensor in the center of the tray 204 will detect the weight of the rice in the packaging bag in real time and transmit the weight information to the control panel 203 through the cable. The operator can preset the required weight on the control panel 203. When the weight fed back by the gravity sensor reaches the set value, the operator can stop feeding and carry out the packaging operation. This design realizes automated weighing control, improves work efficiency and accuracy, and realizes real-time monitoring and control of the weight of rice in the packaging bag. The operator can adjust the required weight on the control panel 203, and the gravity sensor will feed back the weight information of the rice in the packaging bag to the control panel 203 so that the operator can keep track of the weighing situation in time and ensure the accuracy of packaging.

[0031] The usage method and advantages of this utility model: The working process of this packaging machine with a limiting structure is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, different varieties of rice are poured into the storage box 1, and the slider 208 connected to the moving housing 2 is aligned with the discharge port 105. The fixing ring 207 rotates on the threaded screw 206 for easy fixation, so that the housing 2 driven by the slider 208 cannot move. The packaging bag is placed inside the housing 2, and the two sides of the opening of the packaging bag are attached to the fixing plate 202. The magnetic suction piece 205 in the card plate 201 is attached to the magnetic suction piece 205 in the fixing plate 202 for fixation on both sides. The required weight is adjusted on the control panel 203, and the feeding plate 104 is pulled out. The inclined plate 101 in the storage box 1 guides the rice in. The gravity sensor under the tray 204 feeds back to the control panel 203, and then inserts into the discharge port 105 to facilitate the weighing and packaging of different varieties of rice into the packaging bag.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
