Description

Technical Field

[0001] The invention relates to the technical field of color sorters, in particular to a material receiving device for a color sorter with a self-cleaning function. Background Art

[0002] When the conveying device of the crawler color sorter is running, the material is thrown out in a parabolic manner along the conveyor belt. The parabola of the impurities lighter than the material, such as powder and juice, thrown out with the material is shorter than the parabola of the material. These impurities will fall from the middle of the conveying device and the discharge hopper onto the glass of the sorting box below, thus affecting the normal operation of the color sorter.

[0003] At present, the common solution is to set a material receiving box directly under the conveyor belt to prevent dirt from falling onto the glass of the sorting box. However, due to the internal structure of the color sorter, the material receiving box can only be installed in the center of the color sorter. Therefore, for regular cleaning of the material receiving box, the machine can only be stopped and the material receiving box can only be manually disassembled, replaced, cleaned and installed, which is very cumbersome, time-consuming and labor-intensive.

[0019] Figure 2 : Schematic diagram of the installation structure of the smooth conveyor belt of the present invention. DETAILED DESCRIPTION

[0020] Combined with Figure 1-2 , the specific implementation mode of the present invention is described as follows:

[0021] like Figure 1 , 2As shown, a material receiving device of a color sorter with a self-cleaning function comprises a smooth conveyor belt 3, a cleaning scraper 5, an active guide roller 6, a driven guide roller 9, a reversing guide roller 1 4 and a reversing guide roller 2 8.

[0022] The smooth conveyor belt 3 is obliquely installed below the end of the conveyor belt 1 in the color sorter through the support plate 2. The smooth conveyor belt 3 is a loop structure. The two ends of the smooth conveyor belt 3 of the loop structure are respectively installed on the active guide roller 6 and the driven guide roller 9. The active guide roller 6 and the driven guide roller 9 are both installed in the color sorter. The active guide roller 6 is connected to the output shaft of the motor 7, and the motor 7 is a low-speed stepping motor. The rotation of the active guide roller 6 is controlled by the motor 7, thereby driving the smooth conveyor belt 3 to rotate cyclically.

[0023] The reversing guide roller 1 4 is installed inside the smooth conveyor belt 3 of the circulating structure and is closely attached to the smooth conveyor belt 3 in the outgoing direction. The reversing guide roller 2 8 is installed outside the smooth conveyor belt 3 of the circulating structure and is closely attached to the smooth conveyor belt 3 in the incoming direction. The smooth conveyor belt 3 of the circulating structure is an L-shaped structure as a whole. The reversing guide roller 1 4 and the reversing guide roller 2 8 are respectively placed at the right angle inside of the smooth conveyor belt 3 in the outgoing and incoming directions of the L-shaped structure. Compared with the straight plane structure, the setting of the smooth conveyor belt 3 of the L-shaped structure can reduce the installation space of the smooth conveyor belt 3 and improve the space utilization efficiency.

[0024] The cleaning scraper 5 is arranged closely to the smooth conveyor belt 3 and installed inside the color sorter, and two cleaning scrapers 5 are arranged closely to the outer sides of the smooth conveyor belt 3 in the outgoing direction and the incoming direction respectively. The light dirt adhering to the smooth conveyor belt 3 can be effectively scraped off by the two cleaning scrapers 5, thereby improving the efficiency of removing light dirt.

[0025] The cleaning scraper 5 is installed inside the color sorter through a scraper support device. The scraper support device includes a scraper base, a spring and a scraper support. The cleaning scraper 5 is installed on the scraper base. The scraper support is installed on the color sorter support inside the color sorter. The spring is installed between the scraper base and the scraper support. At least two springs are provided and evenly distributed between the scraper base and the scraper support. The axial direction of the spring is perpendicular to the smooth conveyor belt 3. Under the action of the spring of the scraper support device, the cleaning scraper 5 realizes elastic contact with the smooth conveyor belt 3, which can improve the cleaning effect of the smooth conveyor belt 3 and reduce the risk of damage to the smooth conveyor belt 3.

[0026] A dirt box is provided below the smooth conveyor belt 3 and the cleaning scraper 5. A dirt box installation hole is provided on the outer wall of the color sorter, through which the dirt box is inserted into the color sorter and installed on the color sorter frame below the lower side of the smooth conveyor belt 3 and the end of the cleaning scraper 5. The light dirt that falls on the smooth conveyor belt 3, which is non-sticky or has low viscosity and is relatively heavy, slides down to the lower side of the smooth conveyor belt 3 through the smooth conveyor belt 3 and then falls into the dirt box; and the sticky and relatively light part of the light dirt adheres to the smooth conveyor belt 3 and then falls into the dirt box below the lower side of the smooth conveyor belt 3 and the cleaning scraper 5 through its circular rotation and the action of the cleaning scraper 5, thereby realizing the material collection and automatic cleaning of the light dirt. The dirt box originally placed in the center of the color sorter can be installed near the inner wall of the color sorter through the transition effect of the smooth conveyor belt 3. Therefore, the dirt box can be disassembled, replaced and installed without stopping the machine, which is convenient to use.

[0027] An inclined baffle 31 is provided below the end of the conveyor belt 1, and the baffle 31 is mounted on the support plate 2 on the upper side of the smooth conveyor belt 3. The baffle 31 can block the light dirt thrown by the conveyor belt 1 and drop it onto the smooth conveyor belt 3, effectively improving the light dirt receiving effect of the smooth conveyor belt 3.

[0028] The present invention discloses a material receiving device for a color sorter with a self-cleaning function, which makes full use of an inclined smooth conveyor belt 3 to receive light dirt in the material thrown out from the end of the conveyor belt 1, removes sticky dirt on the smooth conveyor belt 3 through the circulation drive of the smooth conveyor belt 3 and a cleaning scraper, and finally collects and processes the dirt in a dirt box located on the outer wall of the color sorter.

[0029] The present invention discloses a color sorter receiving device with a self-cleaning function, which has a compact structure and effectively solves the problem of receiving light dirt thrown out by a conveyor belt inside the color sorter. It does not require machine shutdown for operation, and the light dirt can be removed simply and conveniently. It has a high degree of automation, saves time and effort, and is easy to use.

[0030] The above is an exemplary description of the invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
