Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and more specifically, to a plastic rice feeding machine. Background Technology

[0002] Plastic pellets (i.e., plastic granules) are a core raw material in the plastics processing industry. The conveying process directly affects the efficiency and product quality of subsequent injection molding, extrusion, and other processes. As an automated conveying device, the plastic pellet feeder transports plastic pellets from the storage device to the processing equipment through the feed pipe, greatly replacing manual feeding, reducing labor intensity, and improving production continuity. To ensure the purity of the plastic pellets, the feeder is usually equipped with a filter mechanism at the feed pipe to intercept impurities in the raw material (such as dust, metal shavings, large foreign objects, etc.) and prevent impurities from entering the processing equipment, causing product defects or equipment damage.

[0003] An existing plastic rice feeder was found to have the following issues during use:

[0004] 1. The existing connection method between the filter mechanism and the feed pipe is cumbersome, and the connection mechanism cannot be quickly disassembled. Tools are required to assist in disassembly, which reduces the convenience of the device and thus results in poor practicality.

[0005] 2. Existing filtration mechanisms lack active anti-clogging or auxiliary unblocking designs, resulting in limited unblocking effects. They can only rely on the gravity flushing of the plastic pellets, leading to a poor material throughput rate and thus poor practicality.

[0006] 3. Impurities filtered out by the existing filtration mechanism cannot be quickly removed and cleaned, requiring staff to clean it multiple times, which increases the workload of the staff and thus results in poor practicality. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the problems existing in the prior art, this utility model provides a plastic rice feeding machine to solve the technical problems mentioned in the background art, such as the cumbersome disassembly of the filter mechanism, the poor filtration efficiency affecting the feeding efficiency, and the difficulty in cleaning the impurities after filtration.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a plastic rice feeding machine, comprising a feeding machine, a feeding pipe at the top of the feeding machine, a connecting component at the top of the feeding pipe, the top of the feeding pipe being connected to the bottom of the connecting pipe via the connecting component, four sets of sliding grooves evenly arranged on the inner side of the connecting pipe, connecting blocks vertically sliding within the four sets of sliding grooves, elastic components at the top and bottom of the four sets of connecting blocks, an annular plate on the inner side of the connecting pipe, the outer side of the annular plate being evenly connected to one end of the four sets of connecting blocks, a clamping component on the inner side of the annular plate, an annular block on the inner side of the annular plate via the clamping component, a filter plate at the bottom of the inner side of the annular block, rotating rods rotatably arranged at the bottom of both ends of the inner side of the connecting pipe, a drive motor at the bottom of the left end of the connecting pipe, the right output end of the drive motor being connected to the left end of the rotating rod, striking blocks on both sides of the top of the rotating rod, and fixing blocks at the bottom of both sides of the inner side of the annular plate, with the bottom of both sets of fixing blocks in close contact with the top of the striking blocks.

[0011] This utility model is further configured such that the connecting component includes a mounting ring, the inner side of the mounting ring and the bottom of the outer side of the connecting pipe are rotatably connected, and the bottom of the inner side of the mounting ring and the top of the outer side of the feed pipe are both provided with threaded ends. The bottom of the outer side of the mounting ring is threadedly connected to the top of the outer side of the feed pipe through the threaded ends. This enables convenient assembly and disassembly of the connecting pipe and the feed pipe, drives the mounting ring to rotate, and completes the connection and disassembly through the engagement or disengagement of the threaded ends. It can be operated without tools, replacing the traditional tightening and disassembly of multiple sets of bolts, greatly shortening the equipment assembly and maintenance time, and improving the emergency response capability of the production line.

[0012] The present invention is further configured such that the elastic component includes multiple sets of connecting springs, and multiple sets of connecting springs are provided at the top and bottom of the four sets of connecting blocks. The top and bottom of the four sets of connecting pipe grooves are connected to the other end of the corresponding connecting spring. Through the elastic deformation of the connecting springs, the vibration effect of the annular plate and the filter plate is significantly enhanced. The elastic support of the connecting springs enables the annular plate to generate regular and continuous vibration under the action of the striking block, avoiding vibration jamming or uneven amplitude caused by rigid connection, ensuring that the plastic particles in each area of ​​the filter plate can be vibrated and cleared, and the anti-clogging effect is more uniform.

[0013] The present invention is further configured such that the mounting assembly includes two sets of mounting blocks, an annular groove is provided on the inner side of the annular plate, and slots are evenly provided on both sides of the top of the annular groove. One end of each set of mounting blocks slides into the annular groove through the slots, and the outer sides of the two sets of mounting blocks and the inner sides of the annular groove slide in close contact. The opposite ends of each set of mounting blocks are connected to one end of the annular plate. The tight fit between the mounting blocks and the annular groove, combined with the positioning function of the slots, ensures that the annular blocks will not separate from the annular plate during filtration vibration, avoiding filtration failure caused by filter plate displacement and ensuring filtration accuracy. At the same time, no tools are required; the installation and removal of the annular blocks can be completed simply by lifting the plate, replacing the traditional bolt fixing or welding method, making the cleaning and replacement of the filter plate more efficient.

[0014] The present invention is further provided with a rotating handle on the outer side of the mounting ring, which increases the lever arm of rotating the mounting ring, reduces the force required for operation, and provides a stable grip point to prevent hand slippage during rotation and improve operational safety.

[0015] The present invention is further configured such that an annular sealing ring is provided at the bottom of the connecting pipe, and the top of the feed pipe and the bottom of the annular sealing ring are in close contact; by elastic deformation filling the connection gap, it effectively prevents plastic pellets and dust from leaking from the connection between the connecting pipe and the feed pipe, reducing material waste. At the same time, it can buffer the rigid pressure when installing the threaded connection and avoid wear caused by direct contact between the connecting pipe and the feed pipe.

[0016] The present invention is further provided with lifting plates on both sides of the top of the annular block; this provides a convenient force application point for picking up and putting down the annular block, avoids direct contact with impurities on the surface of the filter plate, keeps hands clean, and makes disassembly easier.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a plastic rice feeding machine, which has the following beneficial effects:

[0019] 1. The drive motor drives the striking block to strike the fixed block, which, together with the elastic component, causes the annular plate and filter plate to vibrate continuously. This prevents plastic pellets from accumulating on the filter plate surface or clogging the mesh, and accelerates the passage of qualified raw materials through the filter plate. This solves the problem of low filtration rate of traditional static filter plates, and is especially suitable for plastic pellets with high viscosity or easy clumping.

[0020] 2. The snap-fit ​​assembly allows the annular block to quickly separate the filter plate from the annular plate. The connecting assembly makes it easy to disassemble and assemble the connecting pipe and the feed pipe. The filter plate can be replaced and cleaned without tools, replacing the cumbersome operation of traditional bolt fixing, greatly shortening the maintenance time and adapting to the needs of continuous operation of the production line.

[0021] 3. The integrated design of the annular block and filter plate, combined with the convenient disassembly of the clamping components, allows impurities on the surface of the filter plate to be directly removed and cleaned along with the annular block. This avoids the difficulty in cleaning impurities caused by the closed structure of traditional filtration mechanisms, reduces the risk of secondary pollution, and at the same time, the modular design of each component facilitates individual maintenance and extends the overall service life of the equipment.

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] Please see Figure 1-5 A plastic rice feeding machine includes a feeding machine 1, a feeding pipe 2 at the top of the feeding machine 1, a connecting component at the top of the feeding pipe 2, the top of the feeding pipe 2 being connected to the bottom of a connecting pipe 3 via the connecting component, four sets of sliding grooves evenly arranged inside the connecting pipe 3, connecting blocks 4 vertically sliding within the four sets of sliding grooves, elastic components at the top and bottom of the four sets of connecting blocks 4, an annular plate 5 inside the connecting pipe 3, the outer side of the annular plate 5 being evenly connected to one end of the four sets of connecting blocks 4, a clamping component inside the annular plate 5, an annular block 6 inside the annular plate 5 via the clamping component, a filter plate 7 at the bottom inside the annular block 6, rotating rods rotatably arranged at the bottom of both ends inside the connecting pipe 3, a drive motor 9 at the bottom of the left end of the connecting pipe 3, the right output end of the drive motor 9 being connected to the left end of the rotating rod 8, striking blocks 10 on both sides of the top of the rotating rod 8, and fixing blocks 11 on both sides of the bottom of the annular plate 5, with the bottom of both sets of fixing blocks 11 tightly attached to the top of the striking blocks 10.

[0032] In this embodiment, during assembly, the connecting pipe 3 is fixed to the feeding pipe 2 via the connecting component at the top of the feeding pipe 2, ensuring unobstructed raw material conveying channel. Plastic pellets enter the connecting pipe 3 through the top of the connecting pipe 3 and first contact the filter plate 7 at the bottom of the inner side of the annular block 6. The mesh on the surface of the filter plate 7 allows qualified plastic pellets to pass through, while impurities are intercepted on the surface of the filter plate 7. During this process, the drive motor 9 is started, and the output end of the motor drives the rotating rods 8 at the bottom of both ends of the inner side of the connecting pipe 3 to rotate. The striking blocks 10 on both sides of the top of the rotating rod 8 rotate synchronously with the rotating rod 8. When the striking blocks 10 rotate to the top, they will contact the bottom of the fixing blocks 11 at the bottom of both sides of the inner side of the annular plate 5 and strike the fixing blocks 11 upwards. The fixing blocks 11 drive the annular plate 5 to move upwards, and the connecting block 4 compresses the top elastic component. After the striking blocks 10 rotate away, the rebound force of the elastic component drives the annular plate 5 to reset downwards, and the connecting block 4 stretches the bottom elastic component. This process is repeated, and the annular plate 5 generates continuous vibration under the action of the elastic component, which drives the filter plate 7 to vibrate synchronously, so that the plastic pellets are filtered quickly.

[0033] More specifically, when the striking block 10 strikes the fixed block 11, the annular plate 5 drives the four sets of connecting blocks 4 to slide upward along the groove inside the connecting pipe 3. The connecting spring 14 at the top of the connecting block 4 is compressed, storing elastic potential energy. After the striking block 10 leaves, the rebound force of the top connecting spring 14 pushes the connecting block 4 downward, and the annular plate 5 resets with the connecting block 4. The connecting spring 14 at the bottom of the connecting block 4 is stretched, further assisting the annular plate 5 in resetting. When the drive motor 9 continues to work, the connecting block 4 slides up and down repeatedly in the groove. The top and bottom connecting springs 14 are alternately compressed and stretched, providing continuous elastic buffering and reset power for the annular plate 5, making the vibration of the annular plate 5 more stable and the amplitude more uniform, driving the filter plate 7 to vibrate efficiently.

[0034] Please see Figure 1 and Figure 4 As one embodiment of the connecting assembly: the connecting assembly includes a mounting ring 12, the inner side of the mounting ring 12 and the outer bottom of the connecting pipe 3 are rotatably connected, the inner bottom of the mounting ring 12 and the outer top of the feed pipe 2 are both provided with threaded ends 13, and the outer bottom of the mounting ring 12 is threadedly connected to the outer top of the feed pipe 2 through the threaded ends 13.

[0035] Specifically, when assembling the connecting pipe 3 and the feed pipe 2, align the bottom of the connecting pipe 3 with the top of the feed pipe 2, hold the rotating handle 17 on the outside of the mounting ring 12, rotate the mounting ring 12, and the threaded end 13 will gradually engage, tightly connecting the connecting pipe 3 and the feed pipe 2. The annular sealing ring 19 will be pressed to achieve a seal. After checking that everything is correct, the installation can be completed.

[0036] Please refer to Figures 2-4 As a further embodiment of the mounting assembly: the mounting assembly includes two sets of mounting blocks 15, an annular groove 16 is provided on the inner side of the annular plate 5, and slots are evenly provided on both sides of the top of the annular groove 16. One end of the two sets of mounting blocks 15 slides into the annular groove 16 through the slots, and the outer side of the two sets of mounting blocks 15 and the inner side of the annular groove 16 slide tightly together. The opposite ends of the two sets of mounting blocks 15 are connected to one end of the annular plate 5.

[0037] Specifically, when installing the ring 12-shaped block 6, hold the lifting plate 18 at the top of the ring block 6, align the two sets of mounting blocks 15 on the outside of the ring block 6 with the slots at the top of the annular groove 16 on the inside of the annular plate 5, slide the mounting blocks 15 into the annular groove 16 along the slots, and then rotate the ring block 6 so that the ring block 6 drives the mounting blocks 15 to rotate, so that the mounting blocks 15 and the slots are no longer aligned. When disassembling, hold the lifting plate 18 and rotate the ring block 6 so that the ring block 6 drives the mounting blocks 15 to slide below the slots, and then pull the ring block 6 upwards. The mounting blocks 15 slide along the annular groove 16 and disengage from the slots, so that the ring block 6 and the filter plate 7 can be removed as a whole. After cleaning impurities or replacing the filter plate 7, the filter plate 7 can be removed.

[0038] In summary, the overall equipment is in use (or running):

[0039] During assembly, align the bottom of the connecting pipe 3 with the top of the feed pipe 2, grasp the rotating handle 17 on the outside of the mounting ring 12, and rotate the mounting ring 12. The threaded end 13 gradually engages, tightly connecting the connecting pipe 3 and the feed pipe 2. The annular sealing ring 19 is compressed to achieve a seal. After checking that everything is correct, the installation is complete. Plastic pellets enter the connecting pipe 3 through the top and first contact the filter plate 7 at the bottom of the inner side of the annular block 6. The mesh on the surface of the filter plate 7 allows qualified plastic pellets to pass through, while impurities are intercepted on the surface of the filter plate 7. During this process, start the drive motor 9. The motor output drives the rotating rods 8 at the bottom of both ends of the inner side of the connecting pipe 3. As the rotating rod 8 rotates, the striking blocks 10 on both sides of the top rotate synchronously with the rotating rod 8. When the striking blocks 10 rotate to the top, they will contact the bottom of the fixing blocks 11 on both sides of the inner side of the annular plate 5 and strike the fixing blocks 11 upward. The fixing blocks 11 drive the annular plate 5 to move upward. The connecting block 4 compresses the top connecting spring 14. After the striking blocks 10 rotate away, the rebound force of the connecting spring 14 drives the annular plate 5 to return to its original position downward. The connecting block 4 stretches the bottom connecting spring 14. This process is repeated. The annular plate 5 generates continuous vibration under the action of the connecting spring 14, which drives the filter plate 7 to vibrate synchronously, so that the plastic pellets can be filtered quickly.

[0040] When the work is completed, when disassembling, hold the lifting plate 18 and rotate the annular block 6 so that the annular block 6 drives the mounting block 15 to slide below the slot. Then pull the annular block 6 upward, and the mounting block 15 slides along the annular groove 16 and disengages from the slot. The annular block 6 and the filter plate 7 can then be removed as a whole. After cleaning the impurities or replacing the filter plate 7, the filter plate 7 can be removed.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
