Description

Technical Field

[0001] This utility model mainly relates to the field of checkweigher technology, specifically to a high-precision integrated equipment for particle product sorting and checkweighing. Background Technology

[0002] In the field of granular product manufacturing and processing, processes such as material sorting, weighing, counting, and rejection of defective products have long relied on manual labor or the coordinated operation of multiple independent machines, resulting in numerous pain points.

[0003] Traditional manual processing methods are inefficient and susceptible to human factors, making it difficult to guarantee the uniformity of material distribution, the accuracy of checkweighing, and the accuracy of counting. This can easily lead to problems such as missed detections and misjudgments. In particular, during mass production, the intensity of manual labor is high, and production costs increase significantly.

[0004] When using multiple independent devices, manual or complex conveying devices are required to connect the devices, which not only occupies a lot of space but also poses risks such as product loss and material jamming during the conveying process. The material sorting equipment often results in product stacking due to the lack of an effective material handling structure, affecting subsequent processes. When the checkweighing equipment is running alone, frequent manual feeding is required, and the calibration process is cumbersome, making it difficult to ensure continuous high-precision detection. The counting and rejection processes lack linkage, which can easily lead to counting deviations or defective products being mixed with qualified products. In addition, traditional equipment is inconvenient to clean and maintain, and after long-term operation, residual impurities in the channels can affect product quality and equipment stability, making it difficult to meet the demands of modern production for high efficiency, accuracy, and stability.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0031] See attached document Figure 1-5 A high-precision particle product sorting and weighing integrated equipment includes an electrical box 1, a feeding module 2, a conveying module 3, a detection station 4, a discharging module 5, a cleaning module 6, a rejection module 7, and multiple material channels 8. The feeding module 2 is connected to the conveying module 3 and the discharging module 5. The detection station 4 is located at the lower end of the conveying module 3. The feeding module 2 includes a feeding platform 201, a vibrating seat 202, and a lifting platform 203. The conveying module 3 includes a pressing mechanism 301 and a feeding mechanism 302. The discharging module 5 includes a counting mechanism 501, a qualified bin 502, and a unqualified bin 503. The qualified bin 502 is also provided with an opening and closing valve plate 504 at the front end. The multiple material channels 8 include a feeding channel 801, a conveying channel 802, and a discharging channel 803. The feeding channel 801, the conveying channel 802, and the discharging channel 803 are all inclined downwards.

[0032] The electrical box 1 serves as the control core of the equipment. Through its complex internal circuitry, it connects to the feeding module 2, conveying module 3, inspection station 4, unloading module 5, cleaning module 6, rejection module 7, and multiple material channels 8, providing power support and command control for each component and ensuring that each part of the equipment operates in an orderly manner according to the preset program.

[0033] The feeding module 2 is precisely connected to the conveying module 3 and the unloading module 5 through a precise mechanical structure, ensuring smooth product flow. The feeding module 2 includes a feeding platform 201, a vibrating seat 202, a lifting platform 203, and a sorting mechanism 204. The sorting mechanism 204 is located inside the feeding platform 201, and the feeding channel 801 is located between the sorting mechanism 204 and the vibrating seat 202. The sorting mechanism 204 is a motor-driven fan plate that acts above the feeding channel 801. When products enter the feeding platform 201, the fan plate rotates continuously, effectively separating stacked products and preventing blockage when products enter the feeding channel 801, ensuring smooth feeding. The vibrating seat 202, through vibration, smoothly conveys the products in the feeding platform 201 to the lifting platform 203. The lifting platform 203 can be adjusted in height according to actual needs, so that the feeding channel 801 can accurately align with the conveying channel 802.

[0034] The conveying module 3 includes a pressing mechanism 301 and a feeding mechanism 302, both located at the upper end of the conveying channel 802. The pressing mechanism 301 is located at the front end of the feeding mechanism 302. The pressing mechanism 301 and the feeding mechanism 302 are fixed to the conveying channel 802 by suitable brackets and connectors to ensure stable positioning during operation. The pressing mechanism 301 includes ejector pins and feeding forks corresponding to multiple channels. The ejector pins and feeding forks are driven by cylinders to move alternately. When a product is conveyed from the conveying channel 802, the ejector pins extend to block the product's advance, the feeding forks retract, and then the ejector pins retract, releasing the product. The fork extends to push individual products to the inspection station, and this cycle repeats, allowing each product to slide onto the inspection station one by one, ensuring the accuracy of the inspection. The feeding mechanism 302 consists of feeding discs arranged in multiple rows of channels. The feeding discs are driven to rotate by cylinders and have multiple feeding blocks. When stopped, the feeding blocks can block the products to be inspected above the inspection station 4, preventing them from falling prematurely. After rotating a certain angle, the feeding blocks will push away the products that have been inspected on the inspection station 4, while releasing the products to be inspected above them to fall into the inspection station 4, thereby realizing the function of inspecting and weighing each product one by one.

[0035] The inspection station 4 is located at the lower end of the conveyor channel 802 and is connected to the conveyor channel 802 through a precise guide structure to ensure that the product can accurately fall into the inspection station. The inspection station 4 includes a calibration unit and an inspection unit. The calibration unit consists of weights and a calibration cylinder. Before the equipment is used, the calibration cylinder extends to accurately place the weights on the weighing sensor, triggering the upper computer to perform a calibration command, thereby completing the equipment calibration process and ensuring the accuracy of subsequent inspections. The inspection unit consists of multiple weighing modules and a measuring pan. When the product slides onto the measuring pan, the weighing module quickly senses the weight of the product and transmits the signal to the upper computer. The upper computer automatically collects the signal and compares it with the preset pass standard to determine whether the product is qualified. After the judgment is completed, the product is pushed into the unloading module 5 through the feeding mechanism 302.

[0036] The feeding module 5 includes a counting mechanism 501, a qualified bin 502, and a non-qualified bin 503. The qualified bin 502 has an opening and closing valve plate 504 at its front end. The counting mechanism 501 is located inside the qualified bin 502 and includes multiple pneumatic telescopic columns arranged in parallel. Each pneumatic telescopic column corresponds to a material channel in the feeding channel 803. When a product that has passed the weighing test falls into the qualified bin 502, the pneumatic telescopic column will descend and block the product once according to its descent. Each time the product is blocked, the counting mechanism 501 counts as 1, thereby achieving accurate statistics on the number of qualified products. The opening and closing valve plate 504 can open and close according to the amount of products stored in the qualified bin 502. When a certain number of products are reached, the valve plate opens and releases the products.

[0037] The multi-row material channel 8 includes a loading channel 801, a conveying channel 802, and a unloading channel 803. The loading channel 801, conveying channel 802, and unloading channel 803 are all inclined downwards. This structure uses gravity to assist in the transport of products and reduces power consumption. The loading channel 801 receives products from the loading module 2 and transports them to the conveying channel 802. The conveying channel 802 transports the products to the inspection station 4 for inspection. The unloading channel 803 transports the inspected products to the qualified bin 502 or the unqualified bin 503 respectively.

[0038] The cleaning module 6 is located at the lower end of the conveying channel 802 and close to the inspection station 4. It includes a flap embedded in the conveying channel 802. The flaps are connected by a connecting rod, and a receiving tray is provided below the flap. When residual products appear in the conveying channel 802 or cause blockage, the flap is flipped by controlling the connecting rod, so that the residual products fall into the receiving tray, thereby cleaning the conveying channel 802 and ensuring the smooth flow of the channel.

[0039] The rejection module 7 is located at the lower end of the feeding channel 803 and close to the inspection station 4. It includes multiple lower valve plates embedded in the feeding channel 803. The multiple lower valve plates are connected by cylinders. The lower end of the rejection module 7 is connected to the defective bin 503. When the inspection station 4 determines that the product is defective, the host computer issues a command to control the corresponding lower valve plate to open. The defective product enters the defective bin 503 through the feeding channel 803 and the opened lower valve plate, so as to achieve accurate rejection of the defective product.

[0040] The execution logic steps are as follows:

[0041] Equipment Start-up and Initialization: When the equipment is turned on, the electrical box 1 starts working, providing power to the feeding module 2, conveying module 3, detection station 4, unloading module 5, cleaning module 6, rejection module 7 and multi-row material channel 8 and transmitting initial control commands. Each component enters the standby state. The verification unit of detection station 4 starts, the verification cylinder extends and places the weight on the weighing sensor. After the verification is completed, the weight is reset, and the equipment enters the ready state.

[0042] Feeding process: The granular product is placed on the feeding platform 201. The motor of the sorting mechanism 204 drives the fan plate to rotate, sorting the product and preventing stacking. The vibrating seat 202 is started, and the product in the feeding platform 201 is conveyed to the lifting platform 203 through vibration. The lifting platform 203 is adjusted according to the height of the feeding channel 801 so that the product can smoothly enter the feeding channel 801. The product slides to the conveying channel 802 by relying on the inclined structure of the feeding channel 801.

[0043] Conveying and distributing process: After the product enters the conveying channel 802, it is conveyed to the pressing mechanism 301. The cylinder of the pressing mechanism 301 drives the ejector pin and the feeding fork to move alternately. The ejector pin extends to block the subsequent product, and the feeding fork extends to push the single product to the bottom of the feeding mechanism 302. At this time, the feeding mechanism 302 is in a stopped state, and the feeding block blocks the product from falling. When the detection station 4 is ready, the cylinder of the feeding mechanism 302 drives the feeding plate to rotate at a certain angle. The feeding block pushes away the product that has been detected on the detection station 4, and at the same time releases the current product so that it falls into the measuring plate of the detection station 4.

[0044] Inspection process: After the product is placed on the measuring plate of inspection station 4, the weighing module of the inspection unit quickly senses the weight of the product and transmits the signal to the host computer. The host computer compares the weight signal with the preset pass standard to determine whether the product is qualified and records the inspection results.

[0045] Material feeding and counting process: If the product is qualified, the feeding mechanism 302 will move again to feed the product into the feeding channel 803. The product will slide into the qualified bin 502. When the product passes the counting mechanism 501, the corresponding pneumatic telescopic column will descend to block once. The counting mechanism 501 will count by 1. This completes the counting of qualified products. After the number of products in the qualified bin 502 reaches the preset number, the opening and closing valve plate 504 at the front end will open to release the product.

[0046] Rejection process: If a product is unqualified, the host computer sends a command to the rejection module 7, and the corresponding cylinder drives the lower valve plate in the feeding channel 803 to open. The unqualified product falls into the unqualified bin 503 through the opened lower valve plate, thus realizing the rejection of the unqualified product.

[0047] Cleaning process: When the equipment has been running for a period of time or when residual products in the conveying channel 802 cause blockage, the cleaning module 6 is activated. The control linkage drives the flap in the conveying channel 802 to flip, so that the residual products fall into the receiving tray below. After cleaning, the flap is reset to ensure that the conveying channel 802 is unobstructed.

[0048] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
