Description
Technical Field
[0001] This utility model belongs to the field of plastic pellet feeding technology, and specifically relates to a mobile special hopper for plastic pellet feeding. Background Technology
[0002] In the field of plastic processing and production, plastic granules are the core raw material. The efficiency and stability of their feeding process directly affect the smoothness of subsequent processing. As a key load-bearing and conveying component in the plastic granule feeding system, the hopper plays an important role in temporarily storing and transferring plastic granules, and has a significant impact on the operation of the entire feeding system. Currently, most hoppers used for feeding plastic pellets on the market adopt a fixed design. Although this type of design can achieve basic feeding functions in specific scenarios, it has gradually revealed obvious defects and shortcomings in actual applications. From the perspective of displacement adjustment, once the fixed hopper is installed and positioned, its position cannot be flexibly adjusted. When the layout of plastic processing equipment changes, the feeding point needs to be moved, or the area around the hopper needs to be cleaned or maintained, the fixed hopper cannot be moved according to actual needs. It can only be disassembled and reinstalled by additional handling equipment or manual labor, which not only consumes a lot of manpower and time costs, but may also affect the connection and sealing between the hopper and the feeding system due to frequent disassembly, thereby interfering with the stability of feeding. Meanwhile, existing fixed hoppers generally lack filtration structures for plastic granules in their structural design. During production, storage, and transportation, plastic granules are easily mixed with impurities, dust, or broken particles. Hoppers without filtration structures directly convey plastic granules to processing equipment, causing impurities to enter the equipment. This not only affects the molding quality of plastic products, resulting in surface defects and substandard performance, but may also cause wear and blockage of internal components of the processing equipment, increasing the probability of equipment failure, shortening equipment lifespan, and further increasing production and maintenance costs. In summary, the shortcomings of existing fixed plastic granule feeding hoppers in terms of displacement flexibility and impurity filtration make their overall use cumbersome and inconvenient, and difficult to meet the demands of modern plastic processing production for efficient, flexible, and clean feeding. Therefore, it is urgent to improve and optimize the existing hopper structure. Utility Model Content

Detailed Implementation
[0014] Example refer to Figures 1 to 4 The mobile special hopper for feeding plastic granules in this embodiment includes a mobile base 1, a support frame 2 fixedly installed on the top of the mobile base 1, a power distribution box 3 fixedly installed on the top of the support frame 2, a controller fixedly installed inside the power distribution box 3, a hopper body 4 fixedly installed on one side of the power distribution box 3, and a filter mechanism 5 provided on the top of the hopper body 4. The mobile base 1 includes a base 11, and a support frame 2 is fixedly installed on the top of the base 11. Universal frames 12 are rotatably connected to the four corners of the bottom of the support frame 2. Universal wheels 13 are rotatably connected inside the universal frames 12. During application, this device, by setting up the mobile base 1, support frame 2, power distribution box 3, hopper body 4, and filtering mechanism 5, allows for flexible movement of the device using the mobile base 1. The universal frames 12 of the mobile base 1, in conjunction with the universal wheels 13, rotate, moving the entire device to a designated position according to the material supply requirements. Unlike existing fixed hoppers, it eliminates the need for disassembly and reassembly, saving manpower and time. After reaching the target location, the device can be stably placed. Then, the controller inside the distribution box 3 controls the hopper body 4 to perform the feeding operation. The filter mechanism 5 on the top of the hopper body 4 can intercept impurities when plastic particles are added, ensuring clean feeding. The support frame 2 provides stable support for the distribution box 3 and the hopper body 4, keeping the components stable during use and preventing shaking from affecting the feeding. This design not only solves the problem of inconvenient displacement of existing fixed hoppers, but also improves the feeding quality through the filter mechanism 5. At the same time, the setting of the controller makes the feeding operation more convenient, thus improving the practicality and efficiency of the device as a whole.
[0015] refer to Figures 2-4 The filtering mechanism 5 includes a latch 51 and a filter cylinder 52. The filter cylinder 52 is inserted into the inside of the hopper body 4. The latches 51 are arranged in a ring at equal intervals and fixedly installed on the upper edge of the outer surface of the hopper body 4. The top of the hopper body 4 is fastened to a top cover 53 by the latches 51, and the top cover 53 covers the top of the hopper body 4. A stepped groove 54 is opened at the upper end of the inside of the hopper body 4. A limit ring 55 is fixedly connected to the upper end of the outer surface of the filter cylinder 52 and is placed inside the stepped groove 54. A universal wheel lock 9 is fixedly installed on the upper outer side of the universal frame 12. After the universal wheel lock 9 is locked, it engages with the universal wheel body 13. During the application of this device, by setting up the filtering mechanism 5 with latches 51, filter cylinder 52, and top cover 53, and the universal frame 12 with universal wheel lock 9, the device can be locked after adjusting its position during use. The wheel lock 9 engages with the caster wheel 13, fixing the device to prevent movement during feeding and ensuring stable feeding. Before adding plastic granules, open the top cover 53 of the hopper body 4, which is fastened by the latch 51, and insert the filter screen 52 with the limiting ring 55 into the hopper body 4. Place the limiting ring 55 in the stepped groove 54 at the upper end of the hopper body 4 to fix the position of the filter screen 52 and prevent displacement. Then close the top cover 53 and lock it with the latch 51 to prevent debris from falling in. When adding granules, the filter screen 52 intercepts impurities to ensure clean feeding. For subsequent cleaning, simply open the latch 51 and remove the top cover 53 to remove the filter screen 52 to remove impurities. The operation is convenient. This design not only improves the stability of the device after movement, but also efficiently filters impurities through the filtration mechanism 5, and simplifies the disassembly and maintenance of the filter screen 52, further optimizing the user experience.
[0016] refer to Figure 1 and Figure 4 The bottom of the distribution box 3 is fixedly equipped with support shafts 6 at both ends. The bottom of the support shafts 6 is fixedly connected to the top of the base 11. An observation window 7 is opened at the lower end of one side of the hopper body 4. The interior of the observation window 7 is equipped with a tempered glass plate. The outer corners of the base 11, distribution box 3, support frame 2, and hopper body 4 are all rounded. An inspection door 8 is hinged to the side of the distribution box 3 away from the hopper body 4. During the application of this device, the support shafts 6, observation window 7, tempered glass plate, rounded corners, and inspection door 8 enhance the connection stability between the distribution box 3 and the base 11 by setting up the support shafts 6, observation window 7, tempered glass plate, rounded corners, and inspection door 8. This prevents the distribution box 3 from shaking during the feeding operation and ensures the accuracy of the internal controller operation. Operators can observe the storage status of plastic granules inside the hopper body 4 through the observation window 7 at the lower end of one side. The tempered glass plate inside the observation window 7 protects the window from damage by the granules without affecting the clarity of observation, facilitating timely replenishment of raw materials. At the same time, the external edges of the base 11, distribution box 3, support frame 2, and hopper body 4 are all rounded, reducing the risk of workers being scratched by sharp edges when operating or moving the device. When the internal components of the distribution box 3 require maintenance, the hinged inspection door 8 can be opened directly for operation without disassembling other structures, simplifying the maintenance process. This design not only improves the overall stability and safety of the device but also optimizes the convenience of daily operation and maintenance through the observation window 7 and inspection door 8, further meeting actual usage needs.
[0017] Operating principle and advantages: During the application of this device, the first step is to move and fix the device. When it is necessary to move the device to the designated feeding position, the operator first releases the universal wheel lock 9, and then pushes the device. Through the cooperation of the universal frame 12 and the universal wheel body 13, the moving seat 1 can drive the entire device to roll flexibly during use, eliminating the need for disassembly and reassembly as with existing fixed hoppers, saving manpower and time costs. When the device reaches the target position, the universal wheel lock 9 is locked, so that the universal wheel lock 9 and the universal wheel body 13 are engaged to fix the universal wheel body 13, preventing the device from moving during feeding and ensuring stable feeding. At the same time, the base 11 of the moving seat 1 provides basic support for the entire device, ensuring overall stability during movement and fixing.
[0018] Next, preparations are made for the filtration mechanism 5. The operator first opens the top cover 53 of the hopper body 4, which is secured to the hopper body 4 by a latch 51. Then, the filter cylinder 52 is inserted into the hopper body 4, so that the limiting ring 55 on the upper surface of the filter cylinder 52 is positioned within the stepped groove 54 at the upper end of the hopper body 4. The stepped groove 54 limits the position of the limiting ring 55, fixing the filter cylinder 52 and preventing it from falling or shifting when plastic granules are added later. After installing the filter cylinder 52, the top cover 53 is closed and secured with the latch 51 to prevent external debris from entering the hopper body 4. This process prepares the hopper for subsequent plastic granule filtration, preventing impurities from entering later processing stages.
[0019] Then, the plastic granules are added and filtered. The operator opens the top cover 53 and pours the plastic granules into the hopper body 4. As the granules fall, they pass through the filter cylinder 52, which filters out impurities, dust, and broken particles. Qualified granules pass through the filter cylinder 52 and are temporarily stored at the bottom of the hopper body 4, while impurities are trapped inside. During the addition process, the operator can observe the amount of plastic granules stored inside through the observation window 7 at the lower side of the hopper body 4. The observation window 7 is equipped with a tempered glass plate, which protects the window without obstructing observation, allowing the operator to monitor the raw material situation promptly and avoid interruptions in the supply due to over- or under-addition, thus further improving the continuity of the supply.
[0020] Finally, the feeding operation and subsequent maintenance are carried out. The staff controls the hopper body 4 to feed the filtered plastic granules to the subsequent processing equipment through the controller inside the distribution box 3. The bottom of the distribution box 3 is equipped with support shafts 6 at both ends. The support shafts 6 enhance the connection stability between the distribution box 3 and the base 11, prevent the distribution box 3 from shaking, and ensure the accuracy of the controller operation. If it is necessary to clean the impurities on the filter screen 52, open the latch 51, remove the top cover 53, take out the filter screen 52 from the inside of the hopper body 4, clean the impurities, and reinsert it. The disassembly and assembly are convenient and reduce the difficulty of maintenance. If the internal components of the distribution box 3 malfunction, the inspection door 8 can be hinged open to inspect and maintain the internal components. The base 11, distribution box 3, support frame 2, and external corners of the hopper body 4 of this device are all set with arcs to reduce the risk of personnel being scratched by sharp edges during use. This technical solution solves the problem of inconvenient and inflexible displacement adjustment of existing fixed hoppers by setting up a universal wheel structure for the movable seat 1, saving manpower and time costs; by setting up a filtration mechanism 5, it solves the problem of impurities affecting product quality and equipment life due to the lack of filtration structure in existing hoppers, ensuring that the plastic particles entering the processing equipment are clean; through structures such as the observation window 7, the supporting shaft 6, the maintenance door 8, and the rounded corners, it further improves the continuity of material supply, the stability of the device, the convenience of maintenance, and the safety of use, optimizes the overall user experience, and enhances the practicality and stability of the device.
