Description

Technical Field

[0001] This utility model relates to the field of fruit pulp foreign matter removal technology, and in particular to a device for removing fruit pulp foreign matter. Background Technology

[0002] After the fruit pulp is made, it needs to be treated to remove foreign matter. Initially, a screen or filter is typically used for preliminary pretreatment to remove larger impurities. However, even after pretreatment, a small number of smaller foreign objects may still remain. To maintain the original flavor of the fruit pulp, the removal of these small foreign objects is currently mostly done manually, but this method is inefficient. Some patents also use removal equipment. For example, patent application number 2024222498140 discloses a fruit pulp foreign object cleaning device. This device uses multiple spaced-apart troughs on a conveyor belt, and when a foreign object is detected in a particular trough, the entire trough of pulp is removed. While this pretreatment reduces the amount of foreign matter in the pulp, discarding the entire trough of pulp upon discovering only a few foreign objects wastes material and increases material costs. Summary of the Invention

[0003] The purpose of this invention is to provide a device for removing foreign matter from fruit pulp, thereby overcoming the technical defects of the prior art that cause waste of fruit pulp material by removing the entire pulp from the feeding tank.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0033] like Figures 1-9 As shown, the device for removing foreign matter from fruit pulp in this embodiment includes: a frame 1, a conveyor belt 2, a feeding assembly 3, a discharging assembly 4, a suction assembly 6, a light source 22, a camera device 5, and a controller.

[0034] Continue to refer to Figures 1-3The conveyor belt 2 is mounted on the frame 1, and an identification area 21 is provided on the conveyor belt 2. This identification area 21 is mainly used for the camera device 5 to take fixed-point photos. In this embodiment, the conveyor belt 2 is transparent, preferably made of transparent PU material. Both sides of the conveyor belt 2 are provided with guards to prevent the material to be detected from spilling out of the belt area. The feeding assembly 3 and the discharging assembly 4 are respectively located at the feeding end and the discharging end of the conveyor belt 2.

[0035] In this embodiment, reference Figures 2-6 The feeding assembly 3 includes a drive unit 31, a peristaltic pump assembly 32, and a nozzle assembly 33. The drive unit 31 drives the peristaltic pump assembly 32 to rotate. Specifically, the drive unit 31 can be a servo motor. The nozzle assembly 33 has multiple nozzles, and the peristaltic pump assembly 32 has multiple linked peristaltic pumps. The servo motor drives the linked peristaltic pumps to rotate. Each peristaltic pump preferably has a controllable switch 34, which allows individual control of the on / off state of each pump. Each nozzle is connected to the outlet of a peristaltic pump via a pipeline. The nozzles are arranged side-by-side at the feed end of the conveyor belt via nozzle supports. The nozzle supports are preferably rotatable and adjustable to accommodate various pulp conveying requirements. The peristaltic pump assembly 32 draws in the pulp, which is then conveyed onto the conveyor belt 2 by the nozzle assembly 33.

[0036] In this embodiment, reference Figure 7 The nozzle orifice is preferably designed as a flat rectangular shape. This allows the fruit pulp to spread evenly on the conveyor belt 2 through the flat rectangular orifice. Spreading evenly on the conveyor belt 2 facilitates the identification of foreign objects in the fruit pulp, thereby enhancing the accuracy of foreign object detection. Moreover, different thicknesses of fruit pulp can be obtained by combining the speed of the belt. Under the drive of the belt, it is ensured that the material can be spread evenly without piling up. The number of nozzles can be selected according to the width of the belt.

[0037] Continue to refer to Figure 8 The discharge assembly 4 includes a discharge hopper 41, which is located at the discharge end of the conveyor belt 2. In this embodiment, the discharge hopper 41 is preferably adjustable up and down, allowing adjustment according to different fruit pulps. More specifically, this embodiment illustrates a design where the discharge assembly 4 also includes a fixing nut 46. The discharge hopper 41 has a rotating shaft 43 and a limiting threaded rod 44 on both sides. The frame 1 has a discharge rotation support 42, which has rotating shaft holes and arc-shaped holes 45 on the outer periphery of the rotating shaft holes on both sides. The rotating shaft of the discharge hopper 41 is rotatably installed in the rotating shaft hole, and the limiting threaded rod 44 extends out of the arc-shaped hole 45. The fixing nut 46 is threaded onto the limiting threaded rod 44. In use, the discharge hopper 41 is adjusted up and down along the arc-shaped hole 45. When adjusted to a certain position, the fixing nut 46 is screwed into the limiting threaded rod 44 for fixation.

[0038] Continue to refer to Figures 2-4 , Figure 9 The suction assembly 6 includes a nozzle support 62, multiple nozzles 61, multiple suction pipes each equipped with a solenoid valve, a suction pump, and a waste bin. The nozzle support 62 is positioned above the conveyor belt 2 between the identification area 21 and the discharge assembly 4. The multiple nozzles 61 are arranged side-by-side on the nozzle support 62, and the width of the multiple side-by-side nozzles 61 is the same as the width of the conveyor belt 2. The suction pump has multiple feed inlets, each of which is connected to a nozzle 61 via a suction pipe. The discharge outlet is connected to the waste bin via a pipeline. During material suction, when fruit pulp or foreign matter passes above a nozzle, the suction pump and the corresponding solenoid valve are activated to draw the fruit pulp or foreign matter through the nozzle 61 into the waste bin.

[0039] In this embodiment, two rows of suction nozzles 61 are preferably provided, with corresponding columns of nozzles in the two rows of suction nozzles 61 staggered to form an array suction range. Furthermore, the suction nozzles 61 are detachably mounted on the suction nozzle support 62. Specifically, the suction nozzles 61 are mounted on the suction nozzle seat 63. One side of the suction nozzle support 62 has a longitudinal slide rail 64, and the bottom of the slide rail 64 has a baffle 67. The suction nozzle seat 63 has a slider 65 and a magnet 66 that can be matched with the slide rail 64. An installation gap is provided between the slider 65 and the magnet 66. The horizontal position of the bottom of the slider 65 is lower than the horizontal position of the bottom of the magnet 66. During installation, the bottom slide rail groove of the slider 65 fits onto the slide rail 64. While fitting along the slide rail 64, the installation gap fits onto the suction nozzle support 62, allowing the magnet to be magnetically attracted to the other side of the suction nozzle support 62. When the baffle 67 abuts against the slider 65, the suction nozzle is in place. By making the suction nozzles 61 detachable, they can be easily replaced when damaged.

[0040] Further reference Figure 1 The light source 22 is mainly used to illuminate the identification area 21. In this embodiment, the light source 22 can be a white light source located below the identification area 21 of the conveyor belt 2 to provide backlighting. The backlighting is suitable for semi-transparent fruit pulp, and the color of the light source can also be adjusted according to the color of the fruit pulp. For opaque fruit pulp, a top light source plus double-side light strips can be used to illuminate the identification area.

[0041] The camera device 5 is positioned above the identification area 21 of the conveyor belt 2. In this embodiment, the camera device 5 can be an industrial camera, such as a single 4K global shutter camera. The camera device 5 is mainly used to periodically capture images of the fruit pulp in the identification area 21. The camera device 5, the suction pump of the suction assembly, the drive device 31, the solenoid valve, and the conveyor belt 2 are all connected to the controller. The conveyor belt 2 transports the fruit pulp in real time. The camera device 5 acquires images of the fruit pulp in the identification area 21, and the controller acquires the coordinates of foreign objects in the fruit pulp images to control the corresponding suction nozzle 61 to suck up the foreign objects.

[0042] When removing foreign objects from the fruit pulp, the conveyor belt 2 is first started. The light source 22 illuminates the identification area 21 of the conveyor belt 2. Different light sources can be adjusted according to different materials; for example, in this embodiment, a backlight source located below the belt is used. The drive device 31 drives the peristaltic pump to extract the fruit pulp and spread it evenly on the conveyor belt 2 through multiple nozzles. The thickness of the spread fruit pulp can be adjusted by adjusting the belt speed and the peristaltic pump extraction speed to ensure that the material is spread evenly and does not accumulate. The conveyor belt transports the fruit pulp horizontally to the identification area 21. The camera device 5 continuously captures images of the fruit pulp according to the width interval of the identification area 21 based on the running position of the conveyor belt. The controller identifies foreign objects in the fruit pulp images. If a foreign object is present, the distance from the foreign object to the corresponding suction nozzle is obtained based on the coordinate position of the foreign object (i.e., the distance along the Y-axis of the grid coordinates corresponding to the belt movement direction, divided into areas according to the grid). The controller uses this distance and the belt running speed to determine the time it takes for the foreign object to reach the suction nozzle. When the foreign object reaches the suction nozzle, the solenoid valve of the corresponding suction nozzle is opened (i.e., the corresponding suction nozzle is determined by the X-axis distance of the grid coordinates) to suck up the foreign object. If there are multiple foreign objects in the pulp image, the foreign objects can be extracted by using the distance between the X-axis of the grid coordinates and the Y-axis of the corresponding grid coordinates to the open suction nozzle.

[0043] It is worth noting that identifying foreign objects in the pulp image and their coordinates can be done using existing image recognition software or models, and grid positioning is a conventional technique. Therefore, the innovation of this embodiment is mainly to control the suction nozzle in conjunction with mechanical structures such as the conveyor belt and camera device to solve the technical problem of foreign object removal.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
