Description

Technical Field

[0001] This application relates to the field of feeding mechanism technology, and in particular to an automated polysilicon conveying system. Background Technology

[0002] When using a conveyor belt to transport polycrystalline silicon particles, the high mobility of the granular material makes it easy for them to fall off the sides of the conveyor belt, resulting in material waste and pollution. Wide conveyor belts are usually used, which not only results in low conveying efficiency, but also causes the conveyor belt to bend under the pressure of a large amount of material. The conveyor belt is also prone to jumping during loading and unloading, resulting in poor conveying stability. Utility Model Content

[0003] The purpose of this application is to provide an automated polysilicon conveying system with high conveying efficiency and good stability.

[0004] To achieve the above objectives, this application provides an automated polysilicon conveying system: including a base, a bracket fixedly connected to the base, a pair of drive wheels rotatably connected to the bracket, a driver provided on the bracket to drive the drive wheels to rotate, the two drive wheels being movably connected to a V-belt, and a support assembly fixedly connected to the bracket, the support assembly including a configuration plate fixedly connected to the bracket, the configuration plate being rotatably connected to a driven roller adapted to roll contact with the upper bottom surface of the V-belt to provide support force to maintain a straight state.

[0005] As a preferred embodiment, the V-shaped band includes a straight portion, and the two sides of the straight portion have inclined portions, which are symmetrical about the straight portion, so that the cross-section of the V-shaped band forms an inwardly concave V-shape.

[0006] As a preferred embodiment, the drive pulley includes a central shaft adapted to roll contact with the straight portion of the V-belt. The two ends of the central shaft have coaxial large conical discs, the diameter of which gradually increases in the direction away from the central shaft. The large conical discs are adapted to roll contact with the inclined portion of the V-belt, thereby improving the fit and contact between the drive pulley and the V-belt, while preventing the V-belt from shifting along the axis of the drive pulley.

[0007] As a preferred embodiment, the driver includes a motor and a reducer fixedly connected to the bracket. The upper end of the bracket has a spindle hole, and the larger diameter end of the large conical disc has a coaxial transmission shaft, which is adapted to pass through the spindle hole and connect to the output end of the reducer to obtain the driver's power.

[0008] As a preferred embodiment, there is a pair of configuration plates that are parallel to each other; there are several driven rollers located between the two configuration plates, and these driven rollers are equidistantly arranged along the length of the configuration plates to provide a uniform forming effect on the upper part of the V-belt.

[0009] As a preferred embodiment, the two configuration plates are provided with aligned limiting shaft holes, the main body of the driven roller is a drum, and the two ends of the drum have end shafts, which are suitable for cooperating with the limiting shaft holes to form a rotating pair, thereby ensuring the stability of the driven roller's position.

[0010] As a preferred embodiment, the base is further provided with a tensioning mechanism, which includes a cylinder fixedly connected to the base. The movable end of the cylinder is rotatably connected to a pressure roller via a traction frame, which is suitable for applying pressure to the V-belt, thereby tensioning the entire V-belt.

[0011] As a preferred embodiment, the traction frame includes a bridge plate fixedly connected to the movable end of the cylinder, and traction plates fixedly connected to both ends of the bridge plate. The traction plates have auxiliary shaft holes. The pressure roller includes a bridge shaft adapted to roll contact with the straight portion of the V-belt. Both ends of the bridge shaft have small conical discs, the diameter of which gradually increases in the direction away from the bridge shaft, adapted to roll contact with the inclined portion of the V-belt. The end of the small conical disc with the larger diameter has a coaxial force transmission shaft, adapted to cooperate with the auxiliary shaft hole to form a rotating pair, ensuring the stable position of the drive wheel.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing the cross-section of the conveyor belt as V-shaped, more polysilicon material can be stacked within a single unit length without falling off, which effectively improves the conveying efficiency of polysilicon material.

[0014] (2) By designing the support components, the upper part of the V-belt is rolled to support it, which reduces the bending deformation caused by the pressure of polysilicon material and reduces the jumping of the conveyor belt during loading and unloading, thereby improving the stability of material conveying.

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The polysilicon automated conveying system shown includes a fixed base 1, on which supports 2 are fixedly connected. There are two sets of supports 2, each set containing two supports. A pair of drive wheels 3 are rotatably connected to each support 2. Each drive wheel 3 is rotatably connected to two supports 2 in its set. A V-belt 4 is movably connected to both drive wheels 3. The V-belt 4 includes a straight section with inclined sections on both sides. The two inclined sections are symmetrical about the straight section, thus forming a V-shape in the cross-section of the V-belt 4. The upper part of the V-shape faces upwards, allowing polysilicon material to be stacked. The belt is relatively high and thick, which can effectively prevent materials from slipping off both sides of the V-belt 4. The lower part of the V-belt 4 faces downward in a V-shape. The drive wheel 3 includes a central shaft 301 for rolling contact with the straight part of the V-belt 4. The two ends of the central shaft 301 have coaxial large conical discs 302. The diameter of the large conical discs 302 gradually increases in the direction away from the central shaft 301. The large conical discs 302 are in rolling contact with the inclined part of the V-belt 4. In this way, the drive wheel 3 can perfectly match the V-belt 4 and drive the V-belt 4 to rotate in a cycle.

[0029] A driver 5 is installed on the bracket 2. The driver 5 includes a motor 501 and a reducer 502 that are fixedly connected to the bracket 2. The output end of the motor 501 is connected to the input end of the reducer 502. A main shaft hole 201 is opened at the upper end of the bracket 2. The larger diameter end of the large conical disc 302 has a coaxial transmission shaft 303 that passes through the main shaft hole 201 and is connected to the output end of the reducer 502. In this way, the driver 5 can drive the drive wheel 3 to rotate smoothly.

[0030] A support assembly 6 is also fixedly connected to the bracket 2 to support the upper part of the V-belt 4. The support assembly 6 includes a configuration plate 610 fixedly connected to the bracket 2. The configuration plate 610 is rotatably connected to a driven roller 620, which rolls in contact with the bottom surface of the upper part of the V-belt 4. There is a pair of configuration plates 610, which are parallel to each other. The driven rollers 620 are located between the two configuration plates 610, and there are several of them. These driven rollers 620 are equidistantly arranged along the length of the configuration plates 610. The plane containing the axis of all driven rollers 620 is parallel to the straight part of the V-belt 4. The two configuration plates 610 are provided with aligned limiting shaft holes 611. The number and position of the limiting shaft holes 611 on each configuration plate 610 correspond to the driven rollers 620. The main body of the driven roller 620 is a roller 621. The two ends of the roller 621 have end shafts 622, which cooperate with the limiting shaft holes 611 to form a rotating pair, thereby restricting the degree of freedom of each driven roller 620.

[0031] A tensioning mechanism 7 is also provided on the base 1. The tensioning mechanism 7 specifically includes a cylinder 710 fixedly connected to the base 1. In practice, only the bottom of the cylinder barrel of the cylinder 710 is fixedly connected to the base 1. The movable end of the cylinder 710 faces upwards and is rotatably connected to a pressure roller 730 via a traction frame 720. The pressure roller 730 is located above the lower part of the V-belt 4 and is used to apply pressure to the V-belt 4. The traction frame 720 includes a bridge plate 721 fixedly connected to the movable end of the cylinder 710. The bridge plate 721 is horizontal, and vertical tension plates 722 are fixedly connected to both ends. The pull plate 722 has a secondary shaft hole 723; the pressure roller 730 includes a bridging shaft 731 for rolling contact with the straight part of the V-belt 4. Both ends of the bridging shaft 731 have small conical discs 732. The diameter of the small conical discs 732 gradually increases in the direction away from the bridging shaft 731, which makes rolling contact with the inclined part of the V-belt 4. This can effectively apply a uniform force to the V-belt 4. The end of the small conical disc 732 with the larger diameter has a coaxial force transmission shaft 733, which cooperates with the secondary shaft hole 723 to form a rotating pair, restricting the degree of freedom of movement of the pressure roller 730.

[0032] Working principle: During operation, the motor 501 starts and drives the V-belt 4 to rotate through the drive wheel 3. Polycrystalline silicon material falls from one end of the V-belt 4 into the V-shaped groove formed by the straight part and two inclined parts on the upper part of the V-belt 4. Therefore, the V-belt 4 can carry a relatively large amount of material per unit length. After the material falls onto the V-belt 4, it will move to the other end with the rotating V-belt 4. Although the upper part of the V-belt 4 is affected by the gravity of the material, the tensioning mechanism 7 tightens the V-belt 4 and the support component 6 supports it, which can effectively reduce the jumping of the V-belt 4. This allows the upper part of the V-belt 4 to remain stable and straight, thus ensuring that the polycrystalline silicon particles are transported smoothly and efficiently between each processing stage.
