Description

Technical Field

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

[0002] Grain and oil are fundamental and strategic commodities vital to the national economy and people's livelihoods. They encompass edible oils, grains, and their processed products. Edible oils (such as peanut oil, soybean oil, and rapeseed oil) are essential for daily diets, with both annual production and consumption at high levels. In the grain and oil processing industry chain, the filling stage is a crucial link between production and consumption. Quantitative filling technology, through precise control of the filling volume, avoids waste during packaging and ensures consistent measurement for each batch, serving as a vital support for large-scale grain and oil production. Currently, the main containers used in grain and oil processing are oil drums. In the oil drum conveying and positioning stage, the guide structure is a core component. Its function is to laterally limit and correct the posture of the oil drum during movement, ensuring that the drum arrives at the pre-set position at the filling station.

[0003] In the prior art, to prevent displacement of oil drums during transportation, two sets of guide plates are generally fixed on both sides of the conveying track. The distance between the two sets of guide plates is adjusted by rotating the adjusting screw to match the outer diameter of the oil drum, thereby limiting the oil drum from shifting to the sides during transportation. However, this structure has the following defects in actual use.

[0004] The existing guide plate spacing relies on manual adjustment by turning the adjusting bolts. When changing oil drums of different specifications, the response is slow and the accuracy is affected by the operator's experience, which can easily lead to problems such as the spacing being too large or too small. When producing oil drums of different specifications alternately, frequent machine stops for adjustment seriously restrict the continuity of the production line.

[0005] Secondly, with prolonged use, the threads of the adjusting bolt are prone to wear. As the wear intensifies, the clearance between the bolt and the connecting parts gradually increases, causing the adjusting bolt to be unable to stably lock the guide plate position. This results in a deviation in the guide plate position, causing the oil drum to shift laterally or tilt slightly during transport. When it reaches the filling station, the filling port is not aligned, causing the grain and oil to spill out, requiring subsequent cleaning and affecting production efficiency. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative filling device for grain and oil processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative filling device for grain and oil processing, including a filling machine, wherein a transmission seat is fixedly installed on the bottom platform of the filling machine, and slide seats are symmetrically fixedly installed on both sides of the transmission seat, and a sliding groove is provided through the interior of the slide seat;

[0008] Cams are rotatably mounted at both ends of the bottom of the transmission seat. T-shaped rods are fixedly mounted at the bottom of both ends of the cams. Two U-shaped plates are symmetrically arranged at both ends of the transmission seat. The U-shaped plates are arranged horizontally and guide rods are fixedly mounted on their upper inner sides. T-shaped rods are fixedly mounted at the bottom of the U-shaped plates. A connecting plate is hinged between T-shaped rods and T-shaped rods. A drive plate is fixedly mounted at the bottom center of the cams. Hydraulic cylinders are symmetrically hinged on both sides of the bottom of the transmission seat. The output ends of the hydraulic cylinders are respectively hinged to the ends of the drive plates away from the center point of the cams.

[0009] Preferably, the upper end of the U-shaped plate is slidably installed inside the groove, and the guide rod is in contact with the container being transported on the surface of the transfer seat.

[0010] Preferably, the first T-shaped rod and the second T-shaped rod are the same size, and the connecting plate has through holes on both sides that are adapted to the two T-shaped rods. The connecting plate is rotatably installed on the surfaces of the first T-shaped rod and the second T-shaped rod through the through holes.

[0011] Preferably, pins are fixedly installed at both ends of the bottom of the transmission base, and the two hydraulic cylinders are rotatably installed on the surface of the pins on the side away from the drive plate.

[0012] Preferably, a storage hopper is fixedly installed on the inner side of the upper end of the filling machine, and two guide hoses are fixedly installed at the bottom of the storage hopper, with filling heads fixedly installed at the bottom of the two guide hoses.

[0013] Preferably, a stand is fixedly installed on one side of the middle part of the transmission base, a vertical groove is opened on the inner side of the stand, and a servo motor is installed on the top of the stand.

[0014] Preferably, an adjusting screw is rotatably installed in the groove inside the stand, and the output end of the servo motor passes through the upper end of the stand and is connected to the top of the adjusting screw via a coupling.

[0015] Preferably, a fixing plate is fixedly installed on the upper surface of the two filling heads. The fixing plate has a threaded hole that matches the adjusting screw on the side surface near the stand. The fixing plate is threaded to the surface of the adjusting screw through the threaded hole and is slidably disposed in the groove.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. A hydraulic cylinder is installed at the bottom of the transmission seat. Its extension and retraction cause the cam to rotate via the drive plate, realizing the automatic adjustment of the guide rod spacing. When it is necessary to change to different specifications of oil drums, the extension and retraction of the hydraulic cylinder drives the cam to rotate. Through the transmission of T-shaped rod one, connecting plate and T-shaped rod two, the U-shaped plate is driven to slide along the slide groove, thereby adjusting the spacing of the guide rods on both sides. There is no need to manually tighten the adjusting bolts. The adjustment process is fast and efficient, which greatly shortens the specification switching time and avoids the restriction of production line continuity caused by frequent machine stop adjustment when producing multiple specifications of oil drums. At the same time, it eliminates the influence of operator experience on adjustment accuracy and prevents the problem of guide failure due to excessive spacing or oil drum jamming due to insufficient spacing.

[0018] 2. The transmission structure driven by a hydraulic cylinder extends and retracts to drive the drive plate, which in turn rotates the cam. Through T-shaped rod one, connecting plate, and T-shaped rod two, the U-shaped plate slides along the slide groove of the slide block, thereby adjusting the guide rod spacing. Compared with the traditional threaded adjustment structure, this structure replaces the adjusting bolt with a hydraulic cylinder hinge transmission, eliminating the wear problem of threaded fit. The wear of components is significantly reduced, which not only greatly extends the service life of the equipment, but also the slide groove of the slide block precisely limits the U-shaped plate. Combined with the rigid transmission of each component, the guiding accuracy is more stable, effectively avoiding the guiding deviation caused by thread wear.

[0019] 3. Through the coordinated structure of the servo motor, adjusting screw, and fixed plate, the height of the filling head can be precisely adjusted, further adapting to the filling needs of oil drums of different sizes. It works synergistically with the guide rod spacing adjustment structure. When the height of the oil drum changes, the servo motor drives the adjusting screw to rotate, causing the fixed plate to slide along the groove of the stand, thereby adjusting the height of the filling head. This ensures that the filling head always maintains a suitable distance from the opening of the oil drum, avoiding filling problems caused by the superposition of differences in oil drum height and guide deviation. The adjustment is highly accurate and responsive, further improving the equipment's adaptability to oil drums of multiple sizes and ensuring the stability and accuracy of quantitative filling.

[0034] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0036] Example: Reference Figures 1-5 A quantitative filling device for grain and oil processing includes a filling machine 1. A transmission seat 101 is fixedly installed on the bottom platform of the filling machine 1. A conveyor belt is provided on the inner side of the upper end of the transmission seat 101 and the conveyor belt is driven by an external motor connected to the transmission seat 101. This structure is a mature existing technology and will not be described in detail. Slide seats 2 are symmetrically fixedly installed on both sides of the transmission seat 101. A sliding groove 201 is opened through the interior of the slide seat 2.

[0037] Cams 4 are rotatably mounted at both ends of the bottom of the transmission seat 101. T-shaped rods 401 are fixedly mounted at the bottom of both ends of the cams 4. Two U-shaped plates 3 are symmetrically arranged at both ends of the transmission seat 101. The U-shaped plates 3 are arranged horizontally and guide rods 301 are fixedly mounted on the inner side of their upper ends. T-shaped rods 402 are fixedly mounted at the bottom of the U-shaped plates 3. A connecting plate 403 is hinged between T-shaped rods 401 and T-shaped rods 402. A drive plate 5 is fixedly mounted at the center of the bottom of the cams 4. Hydraulic cylinders 501 are symmetrically hinged on both sides of the bottom of the transmission seat 101. The output ends of the hydraulic cylinders 501 are respectively hinged to the ends of the drive plate 5 away from the center point of the cams 4.

[0038] Specifically: In this device, the internal slide groove 201 of the slide block 2 is adapted to the upper end of the U-shaped plate 3, providing precise guidance for the lateral sliding of the U-shaped plate 3 and preventing deviation. The two slide blocks 2 on both sides ensure that the U-shaped plate 3 is adjusted synchronously. The cam 4 at the bottom of the transmission seat 101 can rotate around the connection point with the transmission seat 101 to change the position of the T-shaped rod 401 at both ends. The T-shaped rod 401 is connected to the T-shaped rod 402 at the bottom of the U-shaped plate 3 through the hinged connecting plate 403 to form a transmission link. The connecting plate 403 adapts to the angle change of the T-shaped rod 401 as the cam 4 rotates, smoothly converting the circumferential motion of the cam 4 into the lateral thrust of the T-shaped rod 402 to drive the U-shaped plate 3. The U-shaped plate 3 serves as the mounting and transmission carrier for the guide rod 301. Its upper end is embedded in the sliding groove 201 of the slide block 2 for sliding engagement. The inner guide rod 301 directly contacts the oil drum conveyed on the surface of the transmission seat 101. The bottom T-shaped rod 402 receives power from the connecting plate 403. As the U-shaped plate 3 slides along the sliding groove 201, it synchronously drives the guide rod 301 to move, adjusting the spacing. The drive plate 5 at the bottom center of the cam 4 is rigidly connected to the cam 4 at one end and hinged to the output end of the hydraulic cylinder 501 at the other end, converting the extension and retraction force of the hydraulic cylinder 501 into the rotational torque of the cam 4. The hydraulic cylinder 501 is stably hinged to the transmission seat 101 via a pin 502, ensuring flexible rotation during extension and retraction and preventing damage to the rigid components. The symmetrically arranged hydraulic cylinders 501 output balanced driving force, ensuring consistent rotation of the cams 4 on both sides, ultimately achieving precise synchronous adjustment of the guide rod 301 spacing to accommodate oil drums of different outer diameters.

[0039] The upper end of the U-shaped plate 3 is slidably installed inside the slide groove 201. The guide rod 301 is in contact with the container transported on the surface of the transmission seat 101. The T-shaped rod 1 401 and T-shaped rod 2 402 are the same size. The connecting plate 403 has through holes on both sides that are adapted to the two T-shaped rods. The connecting plate 403 is rotatably installed on the surface of T-shaped rod 1 401 and T-shaped rod 2 402 through the through holes. The bottom ends of the transmission seat 101 are fixedly installed with pins 502. The two hydraulic cylinders 501 are rotatably installed on the side away from the drive plate 5 on the surface of the pins 502.

[0040] Specifically: In actual use, the slide groove 201 provides precise sliding limit for the U-shaped plate 3, ensuring that the U-shaped plate 3 can only move in a straight line in the lateral direction, avoiding deviation or jamming of the U-shaped plate 3 during adjustment. The connecting plate 403 is rotatably connected to T-shaped rod 1 401 and T-shaped rod 2 402 through through holes, allowing the connecting plate 403 to flexibly adapt to the angle change of T-shaped rod 1 401 as the cam 4 rotates, smoothly converting the circumferential motion of T-shaped rod 1 401 into the lateral thrust of T-shaped rod 2 402, thus creating a jam-free mechanism. The power transmission link ensures that the rotational force of cam 4 can be effectively converted into the sliding force of U-shaped plate 3. When the output end of hydraulic cylinder 501 extends or retracts, it will push drive plate 5 to drive cam 4 to rotate. During the rotation of cam 4, through the transmission of T-shaped rod 1 401, connecting plate 403 and T-shaped rod 2 402, it drives U-shaped plate 3 to slide along slide groove 201, thereby realizing the adjustment of the spacing of guide rod 301 to adapt to containers with different outer diameter specifications. The entire process ensures the stability and accuracy of guide adjustment through the precise cooperation of each component.

[0041] A storage hopper 102 is fixedly installed on the inner side of the upper end of the filling machine 1. Two guide hoses 6 are fixedly installed at the bottom of the storage hopper 102. A filling head 601 is fixedly installed at the bottom of the two guide hoses 6. The guide hoses 6 are flexible and conductive, which can not only adapt to the lifting action of the filling head 601, but also stably transport raw materials to the filling head 601. A stand 7 is fixedly installed on one side of the middle part of the transmission base 101. A vertical groove is opened on the inner side of the stand 7. A servo motor 8 is installed on the top of the stand 7.

[0042] An adjusting screw 801 is rotatably installed in the groove inside the stand 7. The output end of the servo motor 8 passes through the upper end of the stand 7 through a coupling and is connected to the top of the adjusting screw 801. A fixing plate 802 is fixedly installed on the upper surface of the two filling heads 601. A threaded hole adapted to the adjusting screw 801 is opened through the side surface of the fixing plate 802 near the stand 7. The fixing plate 802 is threadedly connected to the surface of the adjusting screw 801 through the threaded hole and slides in the groove.

[0043] Specifically: In actual use, the adjusting screw 801, in conjunction with the servo motor 8, can convert the rotational power into the linear motion of the fixed plate 802. At the same time, the fixed plate 802 is slidably disposed in the groove of the stand 7. The groove limits the fixed plate 802, preventing it from shifting with the rotation of the screw. This ensures that the fixed plate 802 drives the filling head 601 to rise and fall smoothly in a straight line, ultimately achieving precise adjustment of the height of the filling head 601, adapting to containers of different heights and ensuring accurate injection of raw materials during the filling process, and reducing spillage.

[0044] The working principle of this utility model is as follows: In specific use, the grain and oil raw materials to be filled are first injected into the storage hopper 102 on the inner side of the upper end of the filling machine 1. The bottom of the storage hopper 102 is equipped with a metering valve and a flow meter. The metering valve is connected in series between the storage hopper 102 and the guide hose 6. The flow meter is installed at the outlet end of the metering valve. The grain and oil in the storage hopper 102 first flow through the metering valve and the flow meter, and then flow into the filling head 601 through the guide hose 6. At the same time, the conveying drive component of the transmission seat 101 is started, so that the conveyor belt on the surface of the transmission seat 101 starts to run to transport the oil drum to be filled.

[0045] When the spacing of the guide rods 301 needs to be adjusted according to the outer diameter of the oil drum, the hydraulic cylinders 501 on both sides of the bottom of the control transmission seat 101 are activated. The extension and retraction of the output end of the hydraulic cylinder 501 will drive the drive plate 5, which is hinged to it, to rotate around the center point of the cam 4, thereby driving the cam 4 to rotate synchronously. When the cam 4 rotates, the T-shaped rods 401 at both ends of its bottom will make circular motion. The power is transmitted to the T-shaped rods 402 at the bottom of the U-shaped plate 3 through the hinged connecting plate 403. Since the upper end of the U-shaped plate 3 is slidably installed in the slide groove 201 of the slide seat 2, the T-shaped rods 402 will drive the U-shaped plate 3 to slide laterally along the slide groove 201, and finally realize the adjustment of the spacing of the two sets of symmetrically arranged guide rods 301 until the guide rods 301 are adapted to the side wall of the oil drum to be transported, and complete the pre-processing of the oil drum transport guidance.

[0046] Before the oil drum is conveyed to the filling station by the conveyor belt, the guide rods 301 on both sides will contact the side wall of the oil drum. During the continued conveying of the oil drum, the guide rods 301 will perform lateral limit and posture correction on the oil drum to prevent the oil drum from shifting laterally or tilting slightly, and ensure that the oil drum stops accurately directly under the filling head 601.

[0047] If the height of the oil drum to be filled changes, the servo motor 8 is started to drive the adjusting screw 801 in the groove of the stand 7 to rotate. Since the fixed plate 802 is threadedly connected to the adjusting screw 801 through the threaded hole and is slidably set in the groove, the rotation of the adjusting screw 801 will drive the fixed plate 802 to move vertically up and down along the groove. The fixed plate 802 simultaneously drives the two filling heads 601 fixedly connected to it to rise and fall until the distance between the lower end of the filling head 601 and the opening of the oil drum is appropriate, so as to prevent the grain and oil from overflowing or the filling efficiency from decreasing due to improper distance.

[0048] After the guide rod 301 spacing and filling head 601 height are adjusted, the control system triggers the opening of the quantitative valve at the bottom of the storage hopper 102. After the grain and oil are regulated by the quantitative valve, the flow meter monitors the volume of grain and oil flowing through in real time. When the flow rate reaches the preset filling volume, the control system immediately controls the quantitative valve to close, realizing single quantitative filling. After filling is completed, the conveyor belt transports the oil drum filled with grain and oil to the next process. At the same time, new oil drums to be filled enter the filling station with the conveyor belt. This process is repeated to realize continuous quantitative filling operation.
