Description

Technical Field

[0001] This utility model relates to the field of material conveying and sorting technology, specifically a material sorting and conveying device with an anti-blocking dial mechanism. Background Technology

[0002] Before materials such as sunflower seeds, pumpkin seeds, peanuts, and almonds enter equipment such as color sorters and automatic packaging machines, a sorting and conveying device is needed to gather the materials and output them in a single column. A traditional sorting and conveying device includes a conveyor belt, with a first guard plate and a second guard plate positioned above the conveyor belt along its conveying direction. The first and second guard plates are positioned opposite each other, forming a conveying zone between them. This conveying zone includes a receiving channel, a guide channel, and a single-column channel connected in sequence. The width of the receiving channel is greater than the width of the single-column channel. In the guide channel area, the first guard plate and / or the second guard plate are inclined. In application, the material output from the preceding process is received by the conveyor belt in the receiving channel area. The material is then conveyed forward by the conveyor belt to the guide channel area where it is gathered in the middle. Finally, the material is conveyed forward by the conveyor belt to the single-column channel area and output in a single column to the following process.

[0003] Traditional sorting and conveying devices are prone to bridging and blockage at the junction of the guide channel and the single-row channel when handling flat materials with poor flowability, such as sunflower seeds and peanuts. Therefore, some existing sorting and conveying devices incorporate toothed or scraper mechanisms to manage the material at this junction. However, these mechanisms typically have rigid, right-angled contact points with the material, causing significant damage to fragile materials, resulting in a high rate of surface breakage in the sorting and conveying of sunflower seeds and peanuts. Some existing sorting and conveying devices also incorporate a wheel mechanism at the junction of the guide channel and the single-row channel. This wheel has several teeth evenly distributed around its circumference, which, when rotated, can move bridging material into the single-row channel. However, this method results in material piling up within the single-row channel, and the teeth on existing wheels are often rigid, right-angled teeth, also contributing to a high rate of surface breakage. In addition, sorting and conveying devices need to adjust the width of the single-row channel when applicable to different types of materials. The existing tooth-picking mechanism, scraper mechanism or dial wheel mechanism set at the entrance of the single-row channel is often a complete set of independent components. When changing the material type, the tooth-picking mechanism, scraper mechanism or dial wheel mechanism needs to be replaced as a whole. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material sorting and conveying device with an anti-clogging dial mechanism. The dial mechanism can scrape off bridging materials to ensure that the materials are output smoothly in a single row. At the same time, the arc-shaped surface design of the dial tooth end can reduce damage to the materials.

[0005] The objective of this utility model is achieved through the following technical solution: A material sorting and conveying device with an anti-clogging dial mechanism includes a conveyor belt, on which a first guard plate and a second guard plate are arranged along the conveying direction. The first guard plate and the second guard plate are arranged opposite to each other, and a conveying area is formed between the first guard plate and the second guard plate. The conveying area includes a receiving channel, a guiding channel and a single-row channel connected in sequence. The width of the receiving channel is greater than the width of the single-row channel, and the width of the single-row channel is adapted to the size of the material conveyed by the conveyor belt. It also includes a dial mechanism, which includes a dial wheel with several teeth evenly distributed around its circumference. The dial wheel is rotatably positioned at the junction of the guide channel and the single-row channel. The axis of the dial wheel is perpendicular to the single-row channel. The thickness of the teeth is adapted to the width of the single-row channel. The end of the teeth away from the dial wheel has an arc-shaped surface. The minimum distance between the arc-shaped surface and the top surface of the conveyor belt is adapted to the size of the material conveyed by the conveyor belt. When the dial wheel rotates, the teeth on the side of the dial wheel closest to the conveyor belt move from the single-row channel to the guide channel. The teeth can move the upper layer of material to break the bridging between materials, eliminating the material blockage problem at the junction of the guide channel and the receiving channel. The arc-shaped surface also helps to reduce surface damage to the material.

[0006] Specifically, it also includes a frame, and the dial mechanism also includes a motor. The conveyor belt and the motor are both mounted on the frame. The dial is coaxially and fixedly connected to the output shaft of the motor. The motor is used to provide power for the rotation of the dial.

[0007] Furthermore, the first guard plate is fixedly connected to the frame, and the distance between the second guard plate and the first guard plate is adjustable, making it suitable for single-row sorting and conveying of different materials.

[0008] Specifically, a mounting plate is fixedly connected to the side of the second guard plate away from the first guard plate. The mounting plate is horizontally placed on the top of the frame. The mounting plate has an elongated groove, and the top of the frame has a mounting hole that matches the position of the elongated groove.

[0009] In one specific form, the dial is threadedly connected to the output shaft of the motor, and the dial and teeth can be replaced as a whole as needed.

[0010] In another specific form, the end of the dial away from the motor has several mortises evenly distributed around its circumference. The cross-section of each mortise is trapezoidal. The end of the dial tooth away from the arc-shaped surface is provided with a tenon. The tenon is fitted into the mortise and can be replaced as needed.

[0011] Furthermore, a limiting plate is installed at the end of the dial away from the motor by screws, and the limiting plate abuts against the side of the tenon.

[0012] The beneficial effects of this utility model are: This utility model discloses a material sorting and conveying device with an anti-clogging dial mechanism. The device incorporates a dial mechanism within a traditional sorting and conveying device. This mechanism includes a dial wheel with a plurality of teeth evenly distributed around its circumference. The dial wheel is rotatably positioned at the junction of the guide channel and the single-row channel. When the dial wheel rotates, the teeth on the side closest to the conveyor belt move from the single-row channel to the guide channel, disrupting the bridging between materials and eliminating material blockage at the junction of the guide channel and the single-row channel. The ends of the teeth furthest from the dial wheel have an arc-shaped surface, preventing sharp edges from scraping against the material surface and reducing surface damage. The width of the single-row channel is adjustable, and the dial wheel or individual teeth can be replaced as needed, making this material sorting and conveying device with the anti-clogging dial mechanism suitable for single-row sorting and conveying requirements of different materials.

Detailed Implementation

[0014] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0015] like Figures 1 to 4 As shown, a material sorting and conveying device with an anti-clogging dial mechanism includes a conventional sorting and conveying device and a dial mechanism.

[0016] Traditional sorting and conveying devices include a conveyor belt with a first guard plate 2 and a second guard plate 3 mounted on it. The first and second guard plates 2 and 3 are positioned along the conveying direction of the conveyor belt and are arranged opposite each other to form a conveying zone. This conveying zone includes a receiving channel 4, a guide channel 5, and a single-row channel 6 connected in sequence. The receiving channel 4 has a large width to smoothly receive materials output from the preceding process. In the guide channel 5 area, the first guard plate 2 and / or the second guard plate 3 are inclined, causing the material to be gathered as it passes through the guide channel 5 under the transport of the conveyor belt until it enters the narrower single-row channel 6. The width of the single-row channel 6 is adapted to the size of the material, allowing only a single piece of material to pass through at a time. The material entering the single-row channel 6 can be output in a single row under the transport of the conveyor belt.

[0017] The shifting wheel mechanism includes a shifting wheel 7 with several teeth 8 evenly distributed around its circumference. The shifting wheel 7 is rotatably positioned at the junction of the guide channel 5 and the single-row channel 6. The axis of the shifting wheel 7 is perpendicular to the single-row channel 6. The thickness of the teeth 8 is slightly less than the width of the single-row channel 6. When the shifting wheel 7 rotates, it drives the teeth 8 to rotate, allowing the teeth 8 to extend into the inlet end of the single-row channel 6. When the shifting wheel 7 rotates, the teeth 8 on the side of the shifting wheel 7 closest to the conveyor belt move from the single-row channel 6 towards the guide channel 5. The end of the teeth 8 furthest from the shifting wheel 7 has an arc-shaped surface 9. The minimum distance between the arc-shaped surface 9 and the top surface of the conveyor belt is adapted to the size of the material being conveyed. This distance is greater than the height of a single material laid flat and less than the height of two materials stacked together.

[0018] During operation, the sorting and conveying device continuously rotates the dial wheel 7. On the side of the dial wheel 7 closest to the conveyor belt, each tooth 8 moves sequentially toward the guide channel 5, which can push the material that is bridging at the outlet end of the guide channel 5 toward the guide channel 5. Since the minimum distance between the arc-shaped surface 9 at the end of the tooth 8 and the top surface of the conveyor belt is adapted to the material size, the tooth 8 only pushes aside the material in the upper layer when it is blocked to break the bridging, without interfering with the material in the lower layer. The material in the lower layer can smoothly enter the single-row channel 6 under the conveyor belt. As the guide channel 5 gradually increases in size away from the single-row channel 6, the material displaced by the teeth 8 will not pile up tightly at the front end, thus preventing bridging and blockage. The displaced upper layer material can continue to move closer to the deflector 7 with the conveyor belt. As the deflector 7 continues to rotate, the teeth 8 can periodically move to the working position. If the rotation speed of the deflector 7 is matched with the conveyor belt speed, the upper layer material can be displaced by the teeth 8 every time it moves to the position of the deflector 7, thereby always maintaining a loose material layer at the exit of the guide channel 5 and completely eliminating the problem of material bridging and blockage. An arc-shaped surface 9 is provided at the end of the teeth 8. When the teeth 8 displace the upper layer material, there will be no sharp edges scraping against the material surface, which helps protect the material and results in a lower skin damage rate when used for sorting and conveying sunflower seeds, peanuts, etc.

[0019] In specific implementation, it also includes a frame 1, and the dial mechanism also includes a motor 10. The conveyor belt and the motor 10 are both mounted on the frame 1. The dial 7 is coaxially and fixedly connected to the output shaft of the motor 10. Starting the motor 10 can drive the dial 7 to rotate continuously.

[0020] Furthermore, the first guard plate 2 is fixedly connected to the frame 1, and the distance between the second guard plate 3 and the first guard plate 2 is adjustable, making the sorting and conveying device suitable for single-row sorting and conveying of materials of different sizes. In specific implementation, a mounting plate 12 is fixedly connected to the side of the second guard plate 3 away from the first guard plate 2. The mounting plate 12 is horizontally erected on the top of the frame 1. The mounting plate 12 has a long groove, and the top of the frame 1 has a mounting hole that matches the position of the long groove. A mounting bolt is also provided, which passes through both the mounting hole and the long groove. A nut is threaded onto the mounting bolt. When the nut is tightened, the mounting plate 12 can be fixedly installed on the frame 1 by clamping the nut and the bolt head. When it is necessary to adjust the distance between the second guard plate 3 and the first guard plate 2, the position of the mounting bolt in the long groove can be changed.

[0021] When used for single-row sorting and conveying of materials of different sizes, in addition to adjusting the distance between the second guard plate 3 and the first guard plate 2, it is also necessary to adaptively adjust the thickness of the tooth 8 and the minimum distance between the arc surface 9 and the top surface of the conveyor belt. At the same time, research has shown that when used for single-row sorting and conveying of materials of different shapes such as sunflower seeds, pumpkin seeds, peanuts, and almonds, adopting an appropriate shape in the area of ​​the tooth 8 near the arc surface 9 can further reduce the breakage rate. All of this requires that the tooth 8 be replaced when changing materials.

[0022] In one implementation, the dial 7 and the dial tooth 8 can be machined into a single part. One end of the dial 7 is machined with a threaded hole, and the output shaft of the motor 10 is provided with a screw. The dial 7 and the output shaft of the motor 10 are connected by a thread, allowing the dial 7 to be replaced as a whole quickly.

[0023] In another implementation, the end of the dial wheel 7 furthest from the motor 10 has several mortises evenly distributed around its circumference in the upward direction. The end of the gear 8 furthest from the arc-shaped surface 9 has a tenon, which fits into the mortises. The cross-section of the mortise is trapezoidal, and the opening size of the mortise in the radial direction of the dial wheel 7 is small, preventing the gear 8 from disengaging along the radial direction of the dial wheel 7 when it rotates. Specifically, a limiting plate 11 is installed on the end of the dial wheel 7 furthest from the motor 10 by screws. The limiting plate 11 abuts against the side of the tenon, preventing the gear 8 from disengaging along the axial direction of the dial wheel 7. Thus, the gear 8 and the dial wheel 7 are designed as separate units, allowing the gear 8 to be replaced individually as needed.
