[0003] With the diversification of demand in the personal care market, factories need to simultaneously produce products of different specifications (such as bottles with a diameter of 30-80mm and bags with a thickness of 5-15mm) and different capacities (50ml-2L). However, in existing technologies, the structure of weighing and metering equipment is highly fixed, and the spacing between the baffles of the conveying mechanism and the size of the conveying components cannot be flexibly adjusted. When changing product specifications, a large number of parts need to be disassembled and replaced, which is not only time-consuming and labor-intensive, but also increases the equipment investment cost. In addition, there is a height difference at the connection between the transfer and metering mechanisms of some equipment, which makes the products prone to tipping over and jamming during the transition, resulting in production interruptions. It is difficult to meet the factory's needs for flexible switching between multi-variety, small-batch trial production and large-scale mass production. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an intelligent weighing and metering device for a washing and care factory, including a support frame plate 1. A feeding conveying mechanism 11 and a discharging conveying mechanism 12 are installed on the upper end of the support frame plate 1. A control system 15 is provided above the support frame plate 1. A transfer mechanism 2 is provided on the upper end of the support frame plate 1. A metering mechanism 3 is provided in the middle between the feeding conveying mechanism 11 and the discharging conveying mechanism 12.

[0024] The measuring mechanism 3 includes a fixed frame 31, with multiple sets of trapezoidal support plates 32 arranged above the fixed frame 31. A square groove seat 33 is arranged between the fixed frame 31 and the multiple sets of trapezoidal support plates 32. A weighing component 34 is installed inside the square groove seat 33. A connecting plate 35 is installed at the upper end of the weighing component 34. A cylinder 36 is installed through the top of the inside of the fixed frame 31. Four sets of guide rods 37 are slidably installed through the upper end of the fixed frame 31. The lower ends of the multiple sets of trapezoidal support plates 32 are all fixed to the upper ends of the connecting plate 35. The extended end of the cylinder 36 is fixed to the lower end of the square groove seat 33. The upper ends of the four sets of guide rods 37 are all fixed to the lower ends of the square groove seat 33. The weighing component 34 and the cylinder 36 are both connected to the control system 15 via signals.

[0025] The lower end of the control system 15 is fixed to the upper end of the fixed box 21. The upper end of the support frame plate 1 is equipped with a storage frame plate 13, and one side of the storage frame plate 13 is in contact with one side opening of the baffle in the discharge conveying mechanism 12. A pushing mechanism 14 is installed through one side of the baffle in the discharge conveying mechanism 12. The feeding conveying mechanism 11, the discharge conveying mechanism 12 and the pushing mechanism 14 are all connected to the control system 15 via signals.

[0026] The specific settings and functions of this embodiment are described below. The support frame plate 1 is made of low carbon steel plate by welding to ensure load-bearing strength. The upper end face is fixed with bolts to the fixed box 21 of the feeding conveying mechanism 11, the discharging conveying mechanism 12, the transfer mechanism 2, and the storage frame plate 13. Positioning pin holes are provided at each installation point to reduce vibration and displacement during equipment operation.

[0027] Conveying System: Feeding conveyor 11 and discharging conveyor 12; both adopt a "conveyor belt + drive motor + side baffles" structure. The conveyor belt is made of food-grade PVC material, which is suitable for conveying personal care products (bottled / bagged) to prevent product slippage. The drive motor is a servo drive motor, which can adjust the conveying speed according to the product specifications through the control system 15 to achieve speed matching with the transfer mechanism 2. An opening is reserved on one side baffle of the discharging conveyor 12, and an infrared position sensor is installed at the opening to provide real-time feedback on the product position and provide a signal for the action of the push mechanism 14. A flexible silicone strip is pasted on the inside of the baffle to prevent label wear or bottle deformation caused by collision with the metal baffle during product conveying.

[0028] The fixed frame 31 is made of stainless steel welded into a frame structure, with a reserved lifting channel for the square slot seat 33 inside the frame; 3-6 sets of trapezoidal support plates 32 are evenly distributed above (matched according to the number of conveyor belts 24); the weighing component 34 is installed inside the square slot seat 33, and a high-precision piezoelectric weighing sensor is selected. The sensor surface is covered with a waterproof coating to adapt to the water vapor and detergent residue environment that may exist in the washing and care workshop; the sensor output end is connected to the control system 15 through a shielded cable to reduce the influence of electromagnetic interference (such as the electromagnetic field generated by the workshop motor) on the weight signal.

[0029] The cylinder 36 is a double-acting cylinder. Its extended end is rigidly connected to the lower end of the square slot seat 33 through a flange, which can drive the square slot seat 33 to drive the trapezoidal support plate 32 to achieve rapid lifting and lowering. Four sets of guide rods 37 are evenly distributed around the cylinder 36. The lower end is welded and fixed to the square slot seat 33, and the upper end passes through the fixing frame 31 and is equipped with a linear bearing to avoid inaccurate product weight detection due to tilting. The upper end of the connecting plate 35 is welded and fixed to multiple sets of trapezoidal support plates 32, and the lower end is attached to the force-bearing end of the weighing component 34. It can evenly transfer the product weight on multiple sets of trapezoidal support plates 32 to the weighing component 34, reducing the measurement error caused by uneven force at a single point.

[0030] The outer casing of the control system 15 is a waterproof and dustproof box, and the lower end is fixed to the upper end of the fixed box 21 by bolts to reduce the signal transmission distance. The internal PLC controller and signal conversion module are integrated, and are connected to the feed conveying mechanism 11, the discharge conveying mechanism 12, the variable speed motor 23 of the transfer mechanism 2, the weighing component 34 of the metering mechanism 3 and the cylinder 36, and the push mechanism 14 through wired signals to realize real-time signal interaction throughout the process.

[0031] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, the transfer mechanism 2 includes a fixed box 21. Two sets of rotating rods 22 are rotatably mounted through one end of the fixed box 21. A variable speed motor 23 is mounted on the upper end of the support frame plate 1. Multiple sets of transmission belts 24 are equidistantly mounted on the outer walls of the two sets of rotating rods 22. Two sets of rotating shaft seats 25 are mounted on the inner wall of the fixed box 21. An auxiliary shaft 26 is rotatably mounted on the inner wall of the fixed box 21. A belt drive assembly 27 is provided on one side of the variable speed motor 23, one set of rotating rods 22, and the auxiliary shaft 26. The lower end of the fixed box 21 is connected to the support frame plate 1. The upper ends are fixed, and the outer walls of the two sets of rotating rods 22 are respectively rotatably installed inside the two sets of rotating shaft seats 25. The inner walls of the driving gear, driven gear and auxiliary gear in the belt drive assembly 27 are respectively fixed to the output end of the variable speed motor 23, the outer walls of one set of rotating rods 22 and the auxiliary shaft 26. The variable speed motor 23 is connected to the control system 15 by signal. The upper part of each set of trapezoidal support plates 32 is set in the middle of every two sets of conveyor belts 24. Multiple sets of conveyor belts 24 are set in the middle of the feeding conveyor mechanism 11 and the discharging conveyor mechanism 12.

[0032] The overall effect of this embodiment is as follows: the fixed box 21 is made of welded aluminum alloy profiles with internal reinforcing ribs to ensure structural rigidity; sound-absorbing cotton is pasted on the inner wall of the box to reduce the noise of the variable speed motor 23 and transmission components during operation, meeting the noise standards of the factory workshop; the two sets of rotating rods 22 are made of 45# steel, and keyways are provided on the outer wall to mesh with the internal teeth of the conveyor belt 24 to prevent belt slippage; the multiple sets of conveyor belts 24 are made of polyurethane material, which can withstand the humid environment of the washing and care workshop; the variable speed motor 23 is a variable frequency speed control motor, which drives the rotating rods 22 and the auxiliary shaft 26 to rotate synchronously through the belt transmission assembly 27 (including the driving gear, driven gear, auxiliary gear and transmission belt); the auxiliary shaft 26 is set in the middle of the fixed box 21, which can reduce the sagging of the conveyor belt 24 and ensure smooth transfer.

[0033] Fitting and matching: The upper part of each trapezoidal support plate 32 is embedded in the gap between each two sets of conveyor belts 24, and the top of the trapezoidal support plate 32 is flush with the upper surface of the conveyor belt 24, ensuring that the multiple sets of trapezoidal support plates 32 can move up and down between multiple sets of conveyor belts 24.

[0034] The usage method and working principle of this device: Feeding and conveying: The operator places the washing and care products (such as bottled shampoo and bagged laundry detergent) on the feeding and conveying mechanism 11. The control system 15 starts the drive motor of the feeding and conveying mechanism 11, and the products enter the conveyor belt 24 of the transfer mechanism 2 at a uniform speed along the conveyor belt.

[0035] Transfer and positioning: The variable speed motor 23 drives the rotating rod 22 and the auxiliary shaft 26 to rotate through the belt drive assembly 27, which drives multiple sets of conveyor belts 24 to operate synchronously, and transports the product to the trapezoidal support plate 32 directly above the metering mechanism 3. At this time, the infrared position sensor feeds back the product arrival signal to the control system 15, and the transfer mechanism 2 stops operating.

[0036] Lifting and Metering: The control system 15 starts the cylinder 36, and the cylinder extension pushes the square slot seat 33 to rise along the guide rod 37, which drives the trapezoidal support plate 32 to lift the product (disengage from the conveyor belt 24). The weighing component 34 collects the product weight signal in real time and transmits it to the control system 15. The system compares the detected weight with the preset standard value to determine whether the product is qualified.

[0037] Sorting and storage: If the product is qualified, the cylinder 36 retracts, the product falls back to the conveyor belt 24, the transfer mechanism 2 restarts, and the product is transported to the discharge conveyor mechanism 12, which then sends it to the next production stage; if the product is unqualified, the control system 15 starts the electric push rod of the push mechanism 14 to push the unqualified product into the storage rack 13, thus completing the sorting and storage.

[0038] Cyclic operation: After a single metering and sorting is completed, the control system 15 resets each mechanism, and the feeding conveyor 11 continues to convey the next product, entering the next cycle.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
