Description

Technical Field

[0001] This utility model relates to the technical field of granular material screening equipment, specifically to a vibrating screen for granular material used in cable insulation. Background Technology

[0002] In the process of sorting granular materials, vibrating screening equipment plays a crucial role. Its core function is to apply vibration to make the granular material move and stratify fully on the screen, thereby achieving effective separation of particles of different sizes and improving product quality and production efficiency.

[0003] Currently, common vibrating screening equipment mainly relies on a motor-driven eccentric block to generate centrifugal force, causing the screen to vibrate in a single direction. However, unidirectional vibration often fails to fully disperse and tumble the particles, resulting in a relatively fixed trajectory of the particles on the screen surface. This leads to accumulation and clogging of the screen, preventing some particles from being discharged without sufficient screening agent, reducing screening efficiency and accuracy, and requiring frequent shutdowns for cleaning, thus affecting continuous production. A new vibrating material separating screen is proposed to solve these problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a vibrating screen for cable insulation granules, comprising a frame, a sorting frame mounted on the frame, and a vibration mechanism mounted on the sorting frame. The vibration mechanism includes a U-shaped frame fixed to the ground, four movable rods movably mounted on the U-shaped frame, a movable frame fixed on the four movable rods, four first springs fixed on the movable frame and the U-shaped frame respectively, two guide rods fixed on the movable frame, a movable plate with both ends sleeved on the two guide rods, four second springs sleeved on the two guide rods respectively, round rods fixed at both ends on the sorting frame and the movable plate respectively, two dual-axis motors fixed on the movable plate, four eccentric wheels rotatably mounted at both ends of the two dual-axis motors respectively, and adjusting components mounted on the four eccentric wheels respectively. The four first springs are respectively sleeved on the four movable rods; the four second springs are respectively fixed at both ends on the movable frame and the movable plate; and the two dual-axis motors are symmetrically mounted on the movable plate.

[0006] Specifically, the adjustment assembly includes a plurality of first threaded holes arranged in a ring at equal intervals on the output shaft of the dual-axis motor, a second threaded hole arranged on the eccentric wheel, and bolts that mate with the first threaded holes and the second threaded holes.

[0007] Specifically, the frame includes two sliding grooves fixed on the ground, four movable support rods respectively movably disposed in the two sliding grooves, four shock-absorbing springs respectively fixed on the four movable support rods, four inner support rods respectively movably disposed in the four shock-absorbing springs, four fasteners respectively fixed on the four inner support rods, and four crossbars respectively fixed in the four fasteners; the four crossbars are respectively fixed on the material distribution frame.

[0008] Specifically, the material distribution rack includes a hopper, a screen fixed on the hopper, a first collection bin above the screen, a second collection bin below the screen, a first collection port fixed at the outlet of the first collection bin, and a second collection port fixed at the outlet of the second collection bin.

[0009] Specifically, each of the four movable support rods has four rotatable rollers below it; the four rollers roll within the slide groove.

[0010] The beneficial effects of this utility model are:

[0011] The eccentric angles of the four eccentric wheels can be flexibly adjusted by the adjustment components, ensuring that the eccentric angles of the eccentric wheels at both ends of the same dual-shaft motor are consistent, while the eccentric angles of the eccentric wheels of different dual-shaft motors differ. When the dual-shaft motor starts, the eccentric wheels generate differentiated centrifugal forces due to their different eccentric angles, driving the moving plate to reciprocate up and down while simultaneously driving the moving frame to reciprocate horizontally. This causes the material distribution frame to vibrate simultaneously in both the horizontal and vertical directions. This multi-dimensional vibration mode effectively disrupts the accumulation structure of granular materials, significantly reducing material blockage and accumulation on the screen. Compared to traditional screening equipment with single-direction vibration, its screening efficiency is significantly improved. Attached Figure Description

[0023] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-5As shown, the vibrating sieve for cable insulation granules of this utility model includes a frame 1, a sorting frame 2 mounted on the frame 1, and a vibration mechanism 3 mounted on the sorting frame 2. The vibration mechanism 3 includes a U-shaped frame 31 fixed to the ground, four movable rods 32 movably mounted on the U-shaped frame 31, a movable frame 33 fixed on the four movable rods 32, four first springs 34 respectively fixed on the movable frame 33 and the U-shaped frame 31, two guide rods 35 fixed on the movable frame 33, and movable plates 36 with their ends sleeved on the two guide rods 35. Four second springs 37 are sleeved on two guide rods 35; round rods 38 are fixed at both ends on the material distribution frame 2 and the moving plate 36 respectively; two dual-axis motors 39 are fixed on the moving plate 36; four eccentric wheels 40 are rotatably mounted at both ends of the two dual-axis motors 39 respectively; and adjusting components 41 are mounted on the four eccentric wheels 40 respectively; four first springs 34 are sleeved on four moving rods 32 respectively; the two ends of the four second springs 37 are fixed on the moving frame 33 and the moving plate 36 respectively; and the two dual-axis motors 39 are symmetrically arranged on the moving plate 36.

[0026] When using this vibrating material separator, the eccentric angles of the four eccentric wheels 40 are adjusted by adjusting component 41, so that the eccentric angles of the two eccentric wheels 40 at both ends of the same dual-shaft motor 39 are the same. The eccentric angles of the eccentric wheels 40 on different dual-shaft motors 39 are different. After the two dual-shaft motors 39 are started, due to the different eccentric angles of the eccentric wheels 40, the eccentric wheels 40 generate differentiated centrifugal force when rotating, which can drive the moving plate 36 to move up and down, and at the same time drive the moving frame 33 to move horizontally back and forth. That is, it can drive the material separator 2 to vibrate in both the horizontal and vertical directions. This multi-dimensional vibration mode can effectively destroy the accumulation structure of the granular material and significantly reduce the clogging and accumulation of granular material on the screen 22. Compared with the traditional single-direction vibration screening equipment, its powder screening efficiency is higher.

[0027] Specifically, the adjustment component 41 includes a plurality of first threaded holes 411 arranged in a ring at equal intervals on the output shaft of the dual-axis motor 39, a second threaded hole 412 arranged on the eccentric wheel 40, and a bolt 413 that mates with the first threaded holes 411 and the second threaded holes 412.

[0028] The adjustment of the adjustment component 41 is to unscrew the bolt 413, rotate the eccentric wheel 40 to the appropriate angle, and then tighten the bolt 413 again. The adjustment is convenient and quick. Compared with the traditional adjustment structure of the eccentric wheel 40 that requires disassembly and reassembly, its operation is significantly more convenient.

[0029] Specifically, the frame 1 includes two sliding grooves 11 fixed on the ground, four movable support rods 12 respectively movably disposed in the two sliding grooves 11, four shock-absorbing springs 13 respectively fixed on the four movable support rods 12, four inner support rods 14 respectively movably disposed in the four shock-absorbing springs 13, four fasteners 15 respectively fixed on the four inner support rods 14, and four crossbars 16 respectively fixed in the four fasteners 15; the four crossbars 16 are respectively fixed on the material distribution frame 2.

[0030] Specifically, four rollers 17 are rotatably provided below the four movable support rods 12; the four rollers 17 roll within the slide groove 11.

[0031] In the frame structure 1, four movable support rods 12 are rotatably mounted in the ground groove 11 via rollers 17. Together with the internal shock-absorbing springs 13 and internal support rods 14, they form a three-stage shock absorption and buffer structure. When the material distribution frame 2 undergoes multi-dimensional vibration, the rolling movement of the movable support rods 12 along the groove 11 effectively releases horizontal vibration stress, while the shock-absorbing springs 13 absorb vertical vibration energy, reducing the vibration amplitude transmitted to the ground by more than 60%. This prevents equipment vibration from interfering with surrounding facilities and also reduces fatigue wear on the connecting parts between the movable support rods 12 and the frame 1, extending their service life.

[0032] Specifically, the material distribution rack 2 includes a hopper 21, a screen 22 fixed on the hopper 21, a first collection bin 23 above the screen 22, a second collection bin 24 below the screen 22, a first collection port 25 fixed at the outlet of the first collection bin 23, and a second collection port 26 fixed at the outlet of the second collection bin 24.

[0033] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
