Technical Field

[0001] The utility model relates to the technical field of screening equipment for expanded polystyrene raw materials, and particularly relates to a screening equipment for expanded polystyrene raw materials. Background Art

[0002] Expanded polystyrene is a lightweight porous polymer. By adding a blowing agent to polystyrene resin and heating it, a closed honeycomb structure with bubbles is formed. Due to its advantages such as relatively low density, low thermal conductivity, low water absorption, resistance to impact and vibration, heat insulation, sound insulation, moisture-proof, shock absorption, and excellent dielectric properties, it is widely used in many fields.

[0003] Before the existing expanded polystyrene raw materials are deeply processed, they need to be screened to remove unqualified expanded polystyrene raw materials. Usually, a vibrating screen is used to screen the expanded polystyrene raw materials. Since the collection bag cannot be fixed at the qualified raw material discharge port of the vibrating screen, the collection bag can only be sleeved at the discharge port. Due to the lack of fixation of the collection bag, when a certain amount of expanded polystyrene raw materials enter the collection bag, it will drive the collection bag to tilt, which may lead to the deviation of the collection bag and even complete detachment from the vibrating screen. Therefore, it will cause waste of expanded polystyrene raw materials. For this reason, we provide a screening equipment for expanded polystyrene raw materials. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the collection bag cannot be fixed at the discharge port of the screening equipment for expanded polystyrene raw materials in the prior art, and to provide a screening equipment for expanded polystyrene raw materials.

[0006] As a preferred implementation manner, one end of the bidirectional threaded rod is fixedly connected with a turntable, and a limiting piece is fixedly connected to the end of the bidirectional threaded rod away from the turntable.

[0007] As a preferred embodiment, the limiting piece is placed inside the fixed frame, and a rotating groove matching the limiting piece is provided inside the fixed frame.

[0028] In this embodiment, by setting the clamping mechanism 2, the collection bag can be clamped and fixed so that it can be sleeved on the outer surface of the aggregate ring 22, thereby achieving the purpose of collecting the expanded polystyrene raw materials after screening. By setting the bidirectional threaded rod 23, the first splint 25 and the second splint 26 can be driven by threads, and under the guidance of the guide rod 24, the first splint 25 and the second splint 26 can move towards or away from each other simultaneously, so as to fix the collection bag and make the collection bag fit the inner wall of the fixed frame 21. In addition, the clamping and fixing area of the second splint 26 is relatively large, which can fix a larger part of the collection bag and prevent the expanded polystyrene raw materials from leaking out from the lower port of the aggregate ring 22. By setting the limit piece 28, the bidirectional threaded rod 23 can be assisted, so that the bidirectional threaded rod 23 can rotate stably, and then the first splint 25 and the second splint 26 can be driven by threads.

[0029] Embodiment 2

[0030] As Figure 1 、 Figure 2 and Figure 6 shown, an auxiliary mechanism 3 is provided at the bottom of the vibrating screen 1. The auxiliary mechanism 3 includes a support rod 31, the support rod 31 is fixedly connected to the vibrating screen 1, one end of the support rod 31 is fixedly connected with a connecting rod 32, a sleeve rod 33 penetrates through the inside of the connecting rod 32, the sleeve rod 33 is slidably connected to the connecting rod 32, one end of the sleeve rod 33 placed inside the connecting rod 32 is fixedly connected with a stopper 34, the stopper 34 is slidably connected to the connecting rod 32, a chute that fits the stopper 34 is opened inside the connecting rod 32, and a receiving hopper 35 is fixedly connected to the end of the sleeve rod 33 away from the stopper 34.

[0031] In this embodiment, by setting the auxiliary mechanism 3, the collection bag can be received, preventing the collection bag from sagging when there is too much expanded polystyrene raw material in the collection bag, which affects normal feeding. The sleeve rod 33 can slide inside the connecting rod 32, and thus the position of the receiving hopper 35 can be adjusted. When the collection bag is relatively full, the receiving hopper 35 can be slid so that the receiving hopper 35 is far away from the support rod 31, and then the collection bag is in an inclined collection state, thereby keeping the collection bag able to feed normally.

[0032] Working principle:

[0033] As Figures 1 - 6As shown in the figure, when the utility model is in use, the collection bag can be sleeved and fixed first. At this time, the inlet of the collection bag is unfolded and sleeved on the outer surfaces of the first clamping plate 25 and the second clamping plate 26, and is placed between the first clamping plate 25 and the inner wall of the fixed frame 21 and between the second clamping plate 26 and the inner wall of the fixed frame 21. At this time, the turntable 27 is rotated, and the bidirectional threaded rod 23 is driven to rotate by the turntable 27. When the bidirectional threaded rod 23 rotates, the limiting piece 28 is driven to rotate in the rotating groove opened inside the fixed frame 21, so that the bidirectional threaded rod 23 can stably perform threaded driving on the first clamping plate 25 and the second clamping plate 26. At this time, the first clamping plate 25 and the second clamping plate 26 will move in opposite directions simultaneously under the guidance of the guide rod 24, and then gradually clamp and fix the collection bag and make it fit with the inner wall of the fixed frame 21. At this time, the expanded polystyrene raw material can be poured into the feed hopper of the vibrating screen 1, and through the screening of the vibrating screen 1, the qualified expanded polystyrene raw material will vibrate and slide down and converge at the aggregate ring 22. When a large amount of qualified expanded polystyrene raw material enters the collection bag, the receiving hopper 35 can be slid, so that the collection bag is in a slightly inclined collection state. When the receiving hopper 35 slides, the sleeve rod 33 and the stopper 34 will be driven to slide inside the connecting rod 32. When the collection of the collection bag is completed, the turntable 27 can be rotated in the reverse direction again, so that the bidirectional threaded rod 23 performs threaded driving on the first clamping plate 25 and the second clamping plate 26. At this time, the first clamping plate 25 and the second clamping plate 26 will move towards each other simultaneously until the collection bag can be taken off smoothly.

[0034] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
