Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine casting, in particular to a material powder screening mechanism for a feed port of a waste plastic injection molding machine. Background Art

[0002] The injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. It melts thermoplastic plastic particles or heat-fixed plastic particles, and then injects the molten plastic into the mold under high pressure. During the feeding process of the injection molding machine, in order to improve the material efficiency and avoid material cuts, the material is usually injected into the feed hopper, and the feed hopper is used to feed the injection molding machine. However, the plastic particles contain a large amount of impurities, such as slag, dust, etc. The plastic particles in the feed hopper are concentrated, which makes it inconvenient to screen the impurities in the plastic particles, affecting the feeding quality.

[0003] For example, the utility model with application number 201920722345.6 discloses a material screening mechanism for the feed port of a waste plastic injection molding machine, which arranges an inner bucket inside the feed hopper, uses the inner bucket for loading, fixes a screen plate in the inner bucket, uses the screen plate to screen large particles of impurities, and screens qualified plastic particles into the feed hopper through the bottom of the inner bucket, and uses spiral blades at the bottom of the inner bucket to guide the plastic particles, and the plastic particles fall into the feed hopper through the edges of the spiral blades. A dust suction pipe is used to absorb dust in the plastic particles, which effectively solves the problem of concentrated input of plastic particles in the feed hopper in the prior art, which is inconvenient for screening plastic particles, thereby realizing dispersed input of plastic particles, which is beneficial to the screening of plastic particles and improves the feed quality.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This material screening mechanism used for the feed port of the waste plastic injection molding machine can basically screen plastics and impurities. However, after a long period of screening, the mesh of the screening surface will be clogged. The continuously clogged mesh will greatly reduce the screening efficiency of the plastic and even directly affect the screening work. The shutdown process will affect the processing efficiency.

[0006] Therefore, a powder screening mechanism for materials at the feed inlet of a waste plastic injection molding machine is designed to optimize the above-mentioned problem. Utility Model Content

[0007] The main purpose of the utility model is to provide a material powder screening mechanism for a feed port of a waste plastic injection molding machine, so as to solve the related technical problems raised in the above background technology.

[0010] Preferably, a fixing opening is symmetrically provided on the outer side of the separation bucket, an inclined slide is fixed on the outer side of the separation bucket at a position aligned with the fixing opening, and a centralizing frame is provided between the ends of the inclined slide.

[0011] Preferably: a protective layer is provided on the outer side of the separation bucket, and sound-absorbing cotton is provided between the protective layer and the outer side of the separation bucket.

[0012] Preferably, a protective layer is provided on the outer side of the rotating shaft, and the protective layer is a lubricating coating.

[0013] Preferably, the feed pipe is an L-shaped curved pipe, and a guide block is fixed to the inner side wall of the curved part of the feed pipe.

[0015] The beneficial effects of the utility model are:

Through the coordinated use of a separation bucket, a feed pipe, a motor, a rotating shaft, a slide bar, a slide pipe, a slide groove, a fixed pipe, a fixed shaft, a fixed disk, an arc block, a spring, a roller, a screen plate and a brush rack, the waste plastic is poured onto the screen plate in the separation bucket, the motor is started to drive the rotating shaft to rotate, and with the cooperation of the slide bar and the slide groove, the rotating shaft drives the fixed pipe and the screen plate to rotate, and the brush rack at the bottom dredges the mesh holes of the screen plate, and at the same time, the fixed pipe drives the roller to rotate, so that the roller is intermittently lifted by the arc block, and under the action of the spring elastic force, the fixed pipe and the screen plate are rotated and vibrated up and down at the same time, so that the mesh holes of the screen plate to be screened can be continuously dredged while the waste plastic materials are vibrated and screened, so as to improve the screening efficiency. And the purpose of subsequent processing efficiency is achieved, and manpower and material resources are saved, thereby improving the practicality of the material powder screening mechanism for the feed port of the waste plastic injection molding machine; through the coordinated use of the fixed port, the inclined slide and the concentrated frame, the material screened on the top of the screen plate spreads to the surroundings, and the qualified material falls down, and the screened material enters the inclined slide through the fixed port. The material that has not been thoroughly screened can also leak into the separation bucket through the side mesh holes of the screen plate, and the unqualified material enters the inclined slide and falls into the concentrated frame for collection, thereby facilitating the processing work of the staff; through the coordinated use of the protective layer and the sound-absorbing cotton, when the screen plate vibrates up and down, it will generate a certain friction noise with the inner wall of the separation bucket, and the sound is absorbed and blocked by the protective layer and the sound-absorbing cotton, thereby improving the working environment of the staff.
