Description

Technical Field

[0001] This utility model relates to the field of plastic tableware production technology, and in particular to a centralized feeding component for processing plastic lunch boxes. Background Technology

[0002] During the feeding process of plastic lunch boxes, suction feeding is usually used. Its high degree of automation is suitable for plastic processing processes such as injection molding and extrusion that require continuous feeding. That is, plastic granules are extracted from the hopper and transported to the hopper of the processing equipment through the principle of pneumatic conveying. In order to deal with larger particles or impurities mixed in during the feeding process, the plastic granules need to be extracted in a targeted manner.

[0003] For example, Chinese patent application number CN202223390425.7 discloses a feeding device for plastic lunchbox production, including a storage bin for storing plastic granules used in the production of plastic lunchboxes; and a feeding pipeline connected to the storage bin for conveying the plastic granules. By setting relatively sliding partitions inside the storage bin and adjusting their height position inside the bin via a winding mechanism, it can selectively extract plastic granules or dust, ensuring the quality of the injection-molded product. However, its feeding pipeline for conveying plastic granules has a single path. For different batches of plastic lunchbox processing, old material granules from the previous batch often clog the feeding device, affecting the processing of the next batch of new material granules. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a centralized feeding component for plastic lunch box processing, so as to solve the technical problem that the existing technology for conveying plastic granules has a single feeding pipeline path, and for different batches of plastic lunch box processing, the old material granules of the previous batch often get stuck in the feeding device, affecting the processing of the new material granules of the next batch.

[0005] To achieve the above objectives, this utility model provides a centralized feeding assembly for processing plastic lunch boxes, including a frame and storage bins mounted on the frame for storing plastic granules. The storage bins are equipped with feeding pipes, and there are several storage bins, each movably mounted on both sides of the frame. The feeding assembly further includes:

[0006] A lifting plate that can be raised and lowered on the frame;

[0007] Material-pushing rods are slidably disposed on both sides of the lifting plate, and the material-pushing rods cooperate with the material discharge outlet of the storage box in the vertical direction;

[0008] The rotating frame mounted on the machine frame is rotated, with the end of the rotating frame within the rotation path, which can intermittently move each of the storage bins;

[0009] A drive unit 1 for driving the lifting plate to rise and fall and driving the rotating frame to rotate;

[0010] Drive unit two for driving the feed bar to slide.

[0011] Furthermore, the frame has side plates on both sides, the storage bin is movably placed inside the side plates, and a limiting plate is provided at the side end of the storage bin below the side plates.

[0012] Furthermore, the drive unit one includes:

[0013] A drive motor is located at the side end of the frame;

[0014] A lead screw with one end connected to the output end of the drive motor, and the other end of the lead screw rotatably mounted on the frame;

[0015] A slider threaded onto the lead screw;

[0016] A push-pull rod is hinged to the side end of the slider, and the other end of the push-pull rod is hinged to the lifting plate;

[0017] A first bevel gear is located in the middle of the lead screw, and a second bevel gear is located on the frame. The second bevel gear meshes with the first bevel gear, and the rotating bracket is located at the lower end of the second bevel gear.

[0018] Furthermore, the threads on both sides of the lead screw are arranged in opposite directions, and the sliders are threaded onto the threads on both sides respectively.

[0019] Furthermore, the lifting plate is provided with guide slides, and there are two guide slides arranged parallel to each other on both sides of the lifting plate.

[0020] Furthermore, the second drive unit includes a cylinder and a sliding seat. The cylinder is mounted on the lifting plate, the sliding seat is located on the output end of the cylinder, and the sliding seat is also slidably disposed within the guide slide. The feeding rod is located at the lower end of the sliding seat.

[0021] Furthermore, the pressure plate is adjustablely mounted on the feed rod via bolts, and the end face of the yarn sleeve abuts against the end face of the pressure plate.

[0022] Furthermore, in the two states of the cylinder's output end being fully extended and reset, the feeding rod corresponds to the discharge outlet of different storage boxes.

[0023] The beneficial effects of this utility model are as follows: When in use, the feeding rod can move the plastic granules in the corresponding storage box, and at the same time, each storage box will vibrate intermittently to ensure that the plastic granules are fed smoothly. When processing another batch of plastic lunch boxes, new plastic granules need to be replaced. At this time, the lifting plate is driven by the first drive unit to rise, and then the feeding rod is driven by the second drive unit to slide to the corresponding position of another storage box. After the previous storage box is cleaned, the new plastic granules are continuously fed again, thereby avoiding the blockage of the old material granules and affecting the processing of the next batch of new material granules.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] The first aspect of this utility model proposes a centralized feeding component for processing plastic lunch boxes, such as... Figure 1-5 As shown, the system includes a frame 1 and storage bins 2 mounted on the frame 1 for storing plastic granules. The storage bins 2 are equipped with feeding pipes. There are several storage bins 2, each movably mounted on one side of the frame 1. The feeding assembly also includes:

[0035] A lifting plate 3 that can be raised and lowered on the frame 1;

[0036] The material-pushing rods 4 are slidably disposed on both sides of the lifting plate 3, and the material-pushing rods 4 cooperate with the material discharge outlet of the storage box 2 in the vertical direction;

[0037] Rotate the rotating frame 5 mounted on the frame 1. The end of the rotating frame 5 is within the rotation path, which can intermittently move each storage box 2.

[0038] A drive unit 1 used to drive the lifting plate 3 to lift and drive the rotating frame 5 to rotate.

[0039] Drive unit two for driving the material feeding rod 4 to slide.

[0040] In this embodiment, during use, the lifting plate 3 is driven by the drive unit to reciprocate and move up and down, thereby driving the material feeding rod 4 to move up and down synchronously. Since the material feeding rod 4 is in conjunction with the material outlet of the storage box 2 in the vertical direction, it can move the plastic granules in the corresponding storage box 2. At the same time, the drive unit will also drive the rotating frame 5 to rotate. Since the end of the rotating frame 5 is within the rotation path, it can intermittently move each storage box 2, thereby achieving an intermittent vibration effect of each storage box 2, ensuring smooth feeding of plastic granules and avoiding blockage during the feeding process.

[0041] When processing another batch of plastic lunch boxes, new plastic granules are required. At this time, the lifting plate 3 is driven by the first drive unit to rise, and then the material feeding rod 4 is driven by the second drive unit to slide to the corresponding position of another storage box 2. After the previous storage box 2 is cleaned, the new plastic granules are continuously supplied again, so as to avoid the blockage of the old material granules affecting the processing of the next batch of new material granules.

[0042] In this embodiment, as Figure 1 , Figure 2 As shown, the frame 1 has side plates 6 on both sides, and the storage box 2 is movably placed inside the side plates 6. The side end of the storage box 2 is provided with a limiting plate 7 below the side plate 6. The amplitude of the vibration movement of the storage box 2 inside the side plate 6 is limited by the limiting plate 7 provided on the storage box 2.

[0043] In this embodiment, as Figure 3 As shown, the drive unit includes:

[0044] Drive motor 8 is located at one side of the frame 1;

[0045] One end of the lead screw 9 is connected to the output end of the drive motor 8, and the other end of the lead screw 9 is rotatably mounted on the frame 1.

[0046] A slider 10 is threaded onto a lead screw 9;

[0047] A push-pull rod 11 is hinged to the side end of the slider 10, and the other end of the push-pull rod 11 is hinged to the lifting plate 3;

[0048] A first bevel gear 12 is located in the middle of the lead screw 9, and a second bevel gear 13 is located on the frame 1. The second bevel gear 13 meshes with the first bevel gear 12, and the rotating frame 5 is located at the lower end of the second bevel gear 13.

[0049] Specifically, the output of the drive motor 8 rotates alternately in both directions, which drives the lead screw 9 to rotate synchronously. Then, the slider 10 and the push-pull rod 11 drive the lifting plate 3 to perform reciprocating lifting and lowering actions. During the rotation of the lead screw 9, the rotating frame 5 is also driven to rotate via the first bevel gear 12 and the second bevel gear 13. The rotating frame 5 can push the storage box 2. With the weight of the storage box 2 itself, the storage box 2 can vibrate within the side plate 6. The end of the rotating frame 5 is preferably made of rubber rollers to reduce the wear of the rotating frame 5 on the outside of the storage box 2.

[0050] In this embodiment, as Figure 3 As shown, the threads on both sides of the lead screw 9 are reversed, and the slider 10 is threaded onto the threads on both sides to enhance the overall structural strength.

[0051] In this embodiment, as Figure 3As shown, the lifting plate 3 has two guide slides 14, which are arranged parallel to each other on both sides of the lifting plate 3.

[0052] In this embodiment, as Figure 4 As shown, the second drive unit includes a cylinder 15 and a sliding seat 16. The cylinder 15 is mounted on the lifting plate 3, and the sliding seat 16 is located on the output end of the cylinder 15. The sliding seat 16 is also slidably located in the guide slide 14. The material feeding rod 4 is located at the lower end of the sliding seat 16. The sliding seat 16 can be pushed and pulled by the output end of the cylinder 15 to slide in the guide slide 14.

[0053] In this embodiment, as Figure 4 , Figure 5 As shown, several feeding heads 17 are evenly distributed on the feeding rod 4. Both the upper and lower ends of the feeding heads 17 are inclined structures, making it difficult for plastic particles to adhere and easy to clean.

[0054] In this embodiment, when the output end of the cylinder 15 is fully extended and in a reset state, the feeding rod 4 corresponds to the discharge outlet of different storage boxes 2.
