Description

Technical Field

[0001] This utility model relates to the field of grain packaging, and in particular to a quantitative packaging device for grain processing. Background Technology

[0002] Seeds are the kernels of plants, such as corn, wheat, soybeans, and sunflower seeds. They are usually used for planting or food processing. During processing, seeds need to be packaged in fixed quantities. First, fixed-quantity packaging can ensure that seeds (or kernels) are not damp or contaminated during transportation and storage, and maintain their quality characteristics such as moisture and purity, thereby prolonging seed viability.

[0003] During packaging, the bag is fed into an electronic scale by an elevator and automatically weighed according to specifications. During filling, the bag clamp opens the valve bag, and the bag moves to the filling station for quantitative filling of the seeds. The seeds fall slowly into the bag through a buffer hopper, while the dust is collected by a dust collection pipe. Then, the heat sealer seals the bag with double lines to complete the packaging of the seeds.

[0004] In existing technologies, grains are usually packaged in bags. However, when packaging machines transport the bags, they lack guiding and tension adjustment functions, which leads to bag misalignment, wrinkles, or loosening, causing inaccurate filling positions and material spillage. During heat sealing of the bag opening, uneven tension results in poor sealing, air leakage, or bag breakage. In severe cases, the packaging bag may even derail and become stuck, causing equipment downtime and ultimately reducing the packaging qualification rate and production efficiency. To address these issues, a quantitative packaging device for grain processing is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a quantitative packaging device for grain processing, which aims to improve the problem that the packaging bags in the existing quantitative packaging devices for grain processing lack guiding and tension adjustment functions, resulting in a reduced subsequent packaging qualification rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative packaging device for grain processing, comprising a packaging machine body, a motor fixedly connected to the outer wall of the packaging machine body, a drive roller one fixedly connected to the output end of the motor, a drive gear fixedly connected to the outer wall of the drive roller one, a drive roller two rotatably connected to the surface of the packaging machine body, a driven gear fixedly connected to the outer wall of the drive roller two, a guide roller provided on the surface of the packaging machine body, an electric push rod fixedly connected to the outer wall of the packaging machine body, a through groove opened through the outer wall of the packaging machine body, a sliding groove opened in the inner wall of the packaging machine body, a slider slidably connected to the inner wall of the sliding groove, a movable seat fixedly connected to the outer wall of the slider, and a sensing component provided on the outer wall of the guide roller.

[0007] As a further description of the above technical solution: The inner wall of the movable seat is rotatably connected to the guide roller via a bearing seat, and the driving gear meshes with the driven gear.

[0008] As a further description of the above technical solution: The through groove is fitted onto the outer wall of the movable seat, and the sliding groove is located at the center of the through groove.

[0009] As a further description of the above technical solution: The sensing component includes a mounting groove, and a pressure sensor is fixedly connected to the inner wall of the mounting groove.

[0010] As a further description of the above technical solution: The mounting groove is formed on the outer wall of the bearing housing.

[0011] As a further description of the above technical solution: A fixed frame is fixedly connected to the outer wall of the packaging machine body. A positioning frame is hinged to the top of the fixed frame. A rectangular groove is opened on the top of the fixed frame. An insert block is fixedly connected to the bottom of the positioning frame.

[0012] As a further description of the above technical solution: The inner wall of the rectangular groove is adapted to the outer wall of the insert block.

[0013] As a further description of the above technical solution: The top of the fixing frame is recessed, and the bottom of the positioning frame is recessed.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the packaging bag is stably clamped and transported by driving rollers to rotate synchronously in opposite directions. The guide rollers, together with the electric push rods, are raised and lowered through the through-groove trajectory to accurately adjust the tension. The pressure sensor monitors the pressure changes in real time and converts them into electrical signals to feed back to the control system, thereby improving packaging efficiency, accuracy and automation level, and realizing efficient and reliable quantitative packaging.

[0015] 2. In this utility model, the concave and recessed structure of the fixing frame and the positioning frame effectively restricts the lateral displacement of the packaging bag roll material. At the same time, the insert block at the bottom of the positioning frame is precisely inserted into the rectangular groove of the fixing frame to form a stable mechanical lock, ensuring that the roll material is always tightly attached and without loosening during transportation, thereby improving the stability of feeding and the reliability of operation.

Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a quantitative packaging device for grain processing, comprising a packaging machine body 1. The packaging machine body 1 is equipped with a metering device, a filling mechanism, and a control system. The metering device is an electronic scale that precisely controls the grain filling amount through a preset program. The filling mechanism is a hopper that guides the metered grains into the packaging bag. The control system integrates sensors and a PLC to monitor the filling weight in real time and provide feedback for adjustment, ensuring that the weight error of each bag is within the allowable range. Combined with a precise transmission and positioning system for the packaging bag, an efficient and stable quantitative packaging process is ultimately achieved. A motor 6 is fixedly connected to the outer wall of the packaging machine body 1. A drive roller 7 is fixedly connected to the output end of the motor 6. A drive gear 9 is fixedly connected to the outer wall of the drive roller 7. A second drive roller 8 is rotatably connected to the surface of the packaging machine body 1. A driven gear 10 is fixedly connected to the outer wall of the second drive roller 8. The drive gear 9 and the driven gear 10 mesh, causing the second drive roller 8 and the first drive roller 7 to rotate synchronously in opposite directions. For the clamping and transport of packaging bags, the surface of the packaging machine body 1 is equipped with guide rollers 11 to ensure that the packaging bags move stably along a preset trajectory. Multiple sets of guide rollers 11 are provided, and they work in pairs to guide the packaging bags. One set of guide rollers 11 is controlled by an electric push rod 17 to rise and fall along the trajectory of the through groove 12, controlling the tension of the packaging bag during transport. The electric push rod 17 is fixedly connected to the outer wall of the packaging machine body 1 to precisely control the position change of the guide rollers 11. The through groove 12 is opened through the outer wall of the packaging machine body 1, and the sliding groove 13 is opened on the inner wall of the packaging machine body 1. The sliding groove 13 is located at the center of the through groove 12. The inner wall of the sliding groove 13 is slidably connected to a slider 14. The outer wall of the slider 14 is fixedly connected to a movable seat 15. The inner wall of the movable seat 15 is rotatably connected to the guide rollers 11 through a bearing seat 16. The through groove 12 is sleeved on the outer wall of the movable seat 15. The through groove 12 provides a movement trajectory restriction for the rising and falling of the movable seat 15, ensuring the stability of the rising and falling process of the guide rollers 11.

[0020] Reference Figures 4-6 The outer wall of the guide roller 11 is provided with a sensing component, which includes a mounting groove 18 and a pressure sensor 19. The mounting groove 18 is opened on the outer wall of the bearing seat 16, and provides mounting space for the pressure sensor 19 to ensure the stable fixation of the pressure sensor 19. The pressure sensor 19 is fixedly connected to the inner wall of the mounting groove 18, so that the pressure sensor 19 is close to the force point of the guide roller 11, thereby improving the accuracy of the detection data. The pressure sensor 19 can sense the pressure change on the guide roller 11 and convert the mechanical force signal into an electrical signal to feed back to the control system.

[0021] Reference Figures 3-4The outer wall of the packaging machine body 1 is fixedly connected to a fixing frame 2. The top of the fixing frame 2 is recessed. A positioning frame 3 is hinged to the top of the fixing frame 2 to support the roll material. The bottom of the positioning frame 3 is recessed. The recessed structure limits the roll material of the packaging bag and prevents the roll material from sliding laterally during transportation. A rectangular groove 4 is opened on the top of the fixing frame 2. An insert block 5 is fixedly connected to the bottom of the positioning frame 3. The inner wall of the rectangular groove 4 is adapted to the outer wall of the insert block 5. After the insert block 5 is inserted into the rectangular groove 4, a mechanical lock is formed to ensure that the positioning frame 3 and the fixing frame 2 fit tightly and prevent the roll material from loosening.

[0022] Working principle: During the packaging bag placement stage, the packaging bag roll to be used is placed in the concave area at the top of the fixing frame 2. By flipping the positioning frame 3, its bottom is made to fit against the top of the fixing frame 2. At this time, the insert 5 at the bottom of the positioning frame 3 is inserted into the rectangular groove 4 at the top of the fixing frame 2, realizing the stable fixation of the packaging bag roll and providing initial positioning for subsequent transportation. After the device is started, the motor 6 drives the drive roller 7 at the output end to rotate. The drive gear 9 on the outer wall of the drive roller 7 drives the meshing driven gear 10 to rotate, thereby making the drive roller 8 rotate synchronously. The cooperation of the drive roller 7 and the drive roller 8 realizes the power output for conveying the packaging bag. Multiple sets of guide rollers 11 cooperate in pairs to guide the packaging bag in transportation along the preset trajectory, ensuring that the packaging bag moves smoothly on the transportation path. In order to accurately control the tension of the packaging bag during transportation, the device adjusts one set of guide rollers through the electric push rod 17. When the electric push rod 17 extends or retracts, it pushes the movable seat 15 to rise and fall along the trajectory of the through groove 12. The movable seat 15 slides in the slide groove 13 through the slider 14 to maintain stability. The guide roller 11 connected to its inner wall through the bearing seat 16 rises and falls synchronously with the movable seat 15, thereby changing the relative distance between the set of guide rollers 11 and its cooperating guide rollers 11, so as to adjust the tension of the packaging bag. At the same time, the pressure sensor 19 in the mounting groove 18 on the outer wall of the bearing seat 16 of the guide roller 11 constitutes a sensing component, which detects the pressure change generated when the packaging bag comes into contact with the guide roller 11 in real time. This pressure signal can be fed back to the control system as a basis for judging the tension of the packaging bag, assisting the electric push rod 17 to make more precise tension adjustment, ensuring that the packaging bag will not shift due to being too loose or breakage due to being too tight during transportation, and ensuring the stable and efficient operation of the quantitative packaging process.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
