Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically to a plastic cup raw material screening device. Background Technology

[0002] In the manufacturing process of plastic cups, the purity and particle uniformity of raw materials directly affect the quality of the final product. Efficient and precise screening of raw materials is a crucial step in the production process. Current technology uses vibrating screening devices to screen raw materials. These devices rely on the vibration force generated by a vibrating motor to cause the raw materials to vibrate on a screen. Different mesh sizes of the screens are used to classify and screen the raw material particles, separating qualified particles from impurities or unqualified particles. To achieve automatic unloading of the screened material, the screen body of existing vibrating screening devices is mostly designed with an inclined structure. Under the combined action of gravity and vibration, the screened material slides down the inclined screen surface and eventually falls automatically into the corresponding collection box. However, plastic cup raw material particles are relatively smooth and lightweight. When these particles slide on the inclined screen surface, due to their light weight, the gravitational force they experience is small, and the smooth surface also reduces the friction between the particles and the screen surface, resulting in a relatively fast sliding speed. During the rapid descent, the contact time between the particles and the screen is shortened. Some impurities or substandard particles that should have been screened out may be carried into the collection box because they do not make sufficient contact with the screen or pass through the screen holes in time, resulting in incomplete screening. To address this issue, this invention provides a plastic cup raw material screening device. Utility Model Content

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0015] like Figures 1 to 3 As shown, a plastic cup raw material screening device includes: a frame 1 for fixed support.

[0016] A support frame 2 is mounted on top of the frame 1. The bottom of the first end of the support frame 2 is hinged to the top of the frame 1, and the bottom of the second end is connected to the frame 1 via a telescopic mechanism to switch between a horizontal and an inclined state. Preferably, the telescopic mechanism is a cylinder 8, with its bottom hinged to the frame 1 and its piston rod top hinged to the bottom of the first end of the support frame 2. When the cylinder 8 extends, the support frame 2 rotates around the hinge point, causing it and its upper structure to tilt. When the cylinder 8 retracts, the support frame 2 is supported on the frame 1 in a horizontal state, keeping its upper structure horizontal.

[0017] A vibrating screen 3 is mounted above the support frame 2. A vibrating motor 4 is mounted on the outer wall of the vibrating screen 3. The vibrating motor 4 is connected to a control device and can drive the vibrating screen 3 to vibrate, thereby achieving vibratory screening. Connecting platforms 9 are located at the four corners of the top of the vibrating screen 3. The bottom of the connecting platforms 9 is connected to the top of the support frame 2 via elastic elements 10. The elastic elements 10 have excellent elasticity, which can reduce the impact of the vibration of the vibrating screen 3 on the support frame 2 and the machine frame 1. Preferably, the elastic element 10 is a spring.

[0018] The vibrating screen 3 has a structure that is wider at the top and narrower at the bottom. It has a screen plate with screen holes 5 at the top and a discharge port at the bottom. The structure of the vibrating screen 3 makes it easy for the material to be screened to accumulate and be discharged from the discharge port.

[0019] A retaining plate 6 is provided at the top edge of the vibrating screen 3. The retaining plate 6 has an outlet at the first end of the vibrating screen 3. The function of the retaining plate 6 is to block the material located at the top of the vibrating screen 3 and prevent the material from spreading outward. The outlet is located at the first end of the vibrating screen 3. When the material is poured in, the material is close to the second end of the vibrating screen 3 to prevent the material from being discharged directly from the outlet.

[0020] There are two collection boxes 7, one located below the discharge port and the other below the outlet, to receive the screened material.

[0021] The collection box 7 is slidably fitted onto the frame 1. Specifically, the frame 1 is provided with a baffle 11, which forms a groove with an inlet and outlet, and the collection box 7 is slidably fitted into the groove. The sliding collection box 7 is easy to remove.

[0022] Working process: Pour the material to be screened into the top of the vibrating screen 3, start the vibrating motor 4 to vibrate and screen. Part of the material falls into the first collection box 7, and the other part of the material remains on the surface of the vibrating screen 3. After screening is completed, the cylinder 8 is started, which drives the support frame 2 and the vibrating screen 3 to tilt. The material at the top of the vibrating screen 3 falls into the second collection box 7 under the action of gravity.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
