Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of injection molding machine feeding devices, specifically to a plastic granule feeding device for plastic bucket production. Background Technology
[0002] Plastic buckets are widely used in many fields such as chemical, food, and construction due to their advantages such as corrosion resistance, light weight, and low cost. In the production process of plastic buckets, the feeding of plastic granules is the initial and critical step, which directly affects the continuity and stability of production as well as the quality of the product.
[0003] Currently, many plastic bucket manufacturers still use manual feeding. Workers need to move the packaging bags containing plastic granules to the feeding port and then manually pour out the granules. Since the feeding port on the injection molding machine is at a high height, this method not only consumes a lot of manpower, but also makes the labor intensity of workers high and the work efficiency extremely low. Long-term high-intensity work can easily lead to worker fatigue, resulting in untimely and uneven feeding, which seriously affects the production quality of plastic buckets and increases the defect rate. In addition, plastic granules are easy to spill during manual feeding, which not only wastes materials and increases production costs, but also pollutes the production environment and puts a great burden on the cleaning work of the workshop.
[0004] To improve efficiency, some companies often use screw conveyors for feeding. Screw conveyors have the advantages of stable feeding and saving manpower. In addition, screw conveyors can be set at an incline to transport plastic granules from the part near the ground to the hopper part of the injection molding machine at a higher position.
[0005] However, when using screw conveyors for feeding, most screw conveyors can only handle simple plastic granule feeding, lacking the ability to remove lightweight impurities and dust mixed in with the plastic granules during the feeding process. Since plastic granules inevitably contain impurities and dust during production, transportation, and unpacking, direct feeding will result in subsequent product manufacturing containing a significant amount of dust, affecting product quality. Therefore, we propose a plastic granule feeding device for plastic bucket production. Utility Model Content

[0029] Please see Figures 1-4 This utility model provides a technical solution: a plastic granule feeding device for plastic bucket production, including a screw feeder body 1, a discharge pipe 10 fixedly installed at the discharge end of the screw feeder body 1, an injection molding machine feed hopper 11 provided at the discharge pipe 10, the injection molding machine feed hopper 11 being installed on an external injection molding machine, and the end of the discharge pipe 10 being inserted into the injection molding machine feed hopper 11, so that the plastic granules fed by the screw feeder body 1 can be accurately delivered to the injection molding machine feed hopper 11, thereby achieving efficient feeding to the injection molding machine and meeting the requirements of continuous feeding in plastic bucket production;
[0030] Specifically, a feed pipe 12 is fixedly installed at the feed end of the screw feeder body 1, a feed cover 13 is fixedly installed at the top of the feed pipe 12, and a feed box 14 is fixedly installed at the top of the feed cover 13. A front impurity hole 141 is provided in the front side plate of the feed box 14, and an impurity blowing hole 142 connected to the outside is provided on the front side wall of the front impurity hole 141. Two symmetrical fans 15 are fixedly installed on the rear side plate of the feed box 14. The airflow generated by the fans 15 forms a directional flow in the feed box 14, carrying impurities in the plastic particles through the front impurity hole 141 and out through the impurity blowing hole 142, so that the plastic particles are cleaned of impurities before entering the screw feeder body 1, thereby improving the purity of the raw materials.
[0031] In this embodiment, a first inclined plate 143 is fixedly installed on the inner side of the front side plate of the feed box 14, a flared hopper 16 is fixedly installed on the top of the feed box 14, and a second inclined plate 161 is fixedly installed on the rear side wall of the flared hopper 16. Both the first inclined plate 143 and the second inclined plate 161 are inclined downward at 30 to 45 degrees. A first feeding gap 144 is provided between the first inclined plate 143 and the rear side wall of the feed box 14, and a second feeding gap is provided between the second inclined plate 161 and the front side wall of the flared hopper 16. 162. The first feeding gap 144 is located directly below the second inclined plate 161. After the plastic particles enter from the flared hopper 16, they slide down along the second inclined plate 161 to the first feeding gap 144, and then enter the feeding pipe 12 in an orderly manner through the first inclined plate 143, so that the particles can enter the screw feeder body 1 smoothly and orderly, thereby ensuring the stability of feeding. At the same time, after the plastic particles fall along the first inclined plate 143 and the second inclined plate 161, the particles can be dispersed, which is conducive to improving the comprehensiveness of subsequent air classification to remove impurities.
[0032] Specifically, the bottom wall of the front impurity hole 141 is inclined downward at a 30-60 degree angle toward the fan 15, so that the falling plastic particles can fall directly from the feed box 14; the bottom wall of the impurity blowout hole 142 is inclined downward at a 30-60 degree angle toward the outside, so that the blown impurities fall outward along the impurity blowout hole 142, thus achieving the effect of effectively separating plastic particles and impurities.
[0033] Furthermore, a filter bag 22 is provided on the front side of the feed box 14. The filter bag 22 is connected to the impurity blowing hole 142. A rectangular frame 2 is detachably connected to the front side of the feed box 14. An exposure hole 20 connected to the impurity blowing hole 142 is provided at the center of the rectangular frame 2. Multiple support rods 21 are fixedly installed on the front side of the rectangular frame 2. The filter bag 22 is fitted onto the multiple support rods 21. The rear end of the filter bag 22 is fixedly installed on the front side of the rectangular frame 2. The impurities discharged from the impurity blowing hole 142 are collected by the filter bag 22, so that the discharged impurities will not pollute the production environment and achieve the effect of environmentally friendly impurity collection.
[0034] In addition, the support rod 21 is set to tilt downward at 30 to 60 degrees, and the tilt angle of the filter bag 22 is the same as that of the support rod 21, so that the impurities blown out along the impurity blowing hole 142 can enter the filter bag 22 more smoothly; the rectangular frame 2 and the feed box 14 are fixedly connected by multiple fastening screws, which makes it easy to disassemble the rectangular frame 2 and the filter bag 22 as a whole for cleaning.
[0035] When using the plastic pellet feeding device for plastic bucket production of this utility model, the rectangular frame 2 with the filter bag 22 installed is installed on the front side of the feed box 14 by tightening screws, and the filter bag 22 is connected to the impurity blowing hole 142. The injection molding machine feed hopper 11 is installed on the external injection molding machine, and the end of the discharge pipe 10 is inserted into the injection molding machine feed hopper 11.
[0036] During feeding, plastic granules enter the feed box 14 through the flared hopper 16. The granules slide down the second inclined plate 161 to the first feed gap 144, and then are dispersed and orderly entered into the feed pipe 12 through the first inclined plate 143. At the same time, the fan 15 is started. The directional airflow generated by the fan 15 carries impurities and enters the filter bag 22 through the front impurity hole 141 and impurity blowing hole 142 at the feed box 14, thus completing the impurity separation.
[0037] After being separated by air, the pure plastic granules enter the main body 1 of the screw feeder. The main body 1 of the screw feeder conveys the granules to the discharge pipe 10 and accurately drops them into the feed hopper 11 of the injection molding machine, providing continuous material supply for the injection molding machine. When there are many impurities in the filter bag 22, the fastening screws are unscrewed, the rectangular frame 2 is disassembled, the filter bag 22 is cleaned, and after cleaning, it is reinstalled and can be used again.
