Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for processing plastic granules. Background Technology
[0002] Plastic granules refer to granular plastics. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane, etc. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polysilicon, etc. Specialty plastics include thermosetting plastics and functional polymer plastics, etc.
[0003] In the existing production and processing of plastic products, feeding devices are important tools. Traditional feeding devices are in a continuous feeding state during the feeding process, which requires workers to manually stop the machine. They do not have the function of intermittent feeding and quantitative feeding, which is very inconvenient. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for processing plastic granules.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for processing plastic granules includes a distributing box, a storage hopper fixedly installed on the top of the distributing box, support frames fixedly installed on both sides of the bottom of the distributing box, a guide groove fixedly connected to the bottom side of the distributing box, a fixed frame fixedly installed on the right side of the distributing box, a telescopic cylinder fixedly installed at the middle position of the right side of the fixed frame, the telescopic end of the telescopic cylinder extending through the fixed frame to the other side, a fixed plate provided between the distributing box and the fixed frame, the fixed plate being fixedly connected to the telescopic end of the telescopic cylinder via a flange, a movable plate fixedly installed on the top left side of the fixed plate, movable slots being opened on the left and right sides of the distributing box corresponding to the positions of the movable plate, the movable plate being movably installed in the movable slots, a connecting slot being opened on the right half of the movable plate, a bottom plate being provided on the lower left half of the fixed plate, a partition being provided on the right side of the distributing box, the partition being attached to the left side wall of the distributing box, and the left end of the bottom plate entering the distributing box from below the partition.
[0006] As a further embodiment of this utility model, a connecting block is fixedly installed at the middle position of the right end of the base plate, and a lead screw is movably installed in the fixed plate at the position corresponding to the connecting block. The connecting block can be movably sleeved on the lead screw, and the connecting block and the lead screw are threadedly connected.
[0007] As a further embodiment of this utility model, a connecting frame is fixedly installed at the middle position of the right side of the partition, a fixing block is fixedly installed on the right side wall of the distribution box, a connecting rod is fixedly installed at the bottom of the fixing block, the bottom of the connecting rod is movably installed in the connecting frame, and a spring is provided between the fixing block and the connecting frame, with the spring sleeved on the outside of the connecting rod.
[0008] As a further embodiment of this utility model, limit blocks are fixedly installed on both sides of the right end of the base plate, and a fixing rod is fixedly installed inside the fixing plate at the position corresponding to the limit blocks, with the limit blocks movably installed on the fixing rod.
[0009] As a further embodiment of this utility model, an observation window is provided on the side wall of the material distribution box, and a scale is provided on the side of the observation window.
[0010] As a further embodiment of this utility model, a crank handle is movably installed at the bottom of the fixed plate corresponding to the position of the lead screw, and the crank handle is fixedly connected to the bottom of the lead screw.
[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a crank handle drives a lead screw to rotate, which in turn controls a connecting block to move the base plate up and down. Adjusting the position of the base plate on the dispensing box changes the volume of the box, controlling the amount of material dispensed each time. A telescopic cylinder pushes a fixed plate to the left, causing the fixed plate to move the movable plate and the base plate. At this point, the base plate completely covers the bottom of the dispensing box, and the plastic granules in the storage hopper fall into the dispensing box through the connecting groove on the movable plate. Once the dispensing box is full, the telescopic cylinder is activated to reset, at which point the movable plate covers the connection between the storage hopper and the dispensing box, and the base plate moves to the right. The plastic granules in the dispensing box then fall onto a guide groove and are transported to the processing machine, thus achieving both intermittent and quantitative feeding functions, which is very convenient.

At this time, the base plate 9 will completely cover the bottom of the material distribution box 1, and the plastic particles in the storage hopper 2 will fall into the material distribution box 1 through the connecting groove 8 on the movable plate 18. When the material distribution box 1 is full, the telescopic cylinder 7 will be activated to reset. The telescopic cylinder 7 will drive the fixed plate 6 to move to the right. At this time, the movable plate 18 will cover the connection between the storage hopper 2 and the material distribution box 1, and the base plate 9 will also move to the right. At this time, the plastic particles in the material distribution box 1 will fall onto the guide groove 4 and be transported to the processing machine through the guide groove 4. The plastic particles on the base plate 9 will be completely blocked by the partition 10 and remain in the material distribution box 1, thus achieving the functions of intermittent feeding and quantitative feeding, which is very convenient.
