[0028] An embodiment of this utility model provides a checkweighing device with a sensor protection structure, such as... Figures 1-7 As shown, it includes:

[0029] The checkweighing equipment body 100 includes a feeding conveyor line 110 and a weighing conveyor line 120, which are connected to each other.

[0030] The weighing structure 200 includes a base 210 and a weighing sensor 220. The weighing sensor 220 includes a fixed part 230 connected to the base 210 and a suspended part 240. The weighing conveyor line 120 is disposed on the suspended part 240.

[0031] The sensor protection structure 300 includes a support plate 310, which abuts against and supports the suspended part 240.

[0032] The weighing device body 100 comprises a feeding conveying line 110 and a weighing conveying line 120. The feeding conveying line 110 is responsible for conveying the to-be-detected articles onto the weighing conveying line 120. The weighing conveying line 120 is opposite to the feeding conveying line 110 and is used for carrying the articles and weighing. The weighing structure 200 comprises a base 210 and a weighing sensor 220. The base 210 is fixed on the weighing device body 100 and provides support for the weighing sensor 220. The weighing sensor 220 comprises a fixed part 230 and a suspended part 240. The fixed part 230 is connected with the base 210, and the suspended part 240 is used for carrying the weighing conveying line 120. The sensor protection structure 300 comprises a support plate 310, which is designed to abut and support the suspended part 240 of the weighing sensor 220. The support plate 310 functions to prevent the weighing sensor 220 from being deformed or even damaged due to accidental stress during the movement of the weighing device body 100.

[0033] The working principle of the utility model is as follows:

[0034] When the weighing device body 100 needs to be moved, the support plate 310 is used to abut and support the suspended part 240, so as to prevent the weighing sensor 220 from being deformed due to accidental stress.

[0035] The utility model increases the support plate 310 below the weighing sensor 220, effectively protects the sensor, reduces the deformation or damage of the weighing sensor 220 caused by external factors, and improves the accuracy and stability of the weighing device.

[0036] In some embodiments, the support plate 310 is provided with a through slot 320, and the sensor protection structure 300 further comprises fasteners 330 matched with the through slot 320. The support plate 310 can move along the length direction of the through slot 320 under the limiting of the fasteners 330 and be fixed by the fasteners 330.

[0037] The support plate 310 is designed with a through slot 320, and the sensor protection structure 300 further comprises fasteners 330 matched with the through slot 320. These fasteners 330 can be bolts, screws or other forms of fixing devices. The function of the fasteners 330 is to fix the support plate 310 at a specific position in the through slot 320 after the support plate 310 is moved to the appropriate position, so as to ensure that the support plate 310 stably supports the weighing sensor 220. The support plate 310 can move along the length direction of the through slot 320 under the limiting of the fasteners 330, which means that the position of the support plate 310 can be adjusted according to the specific position of the weighing sensor 220 or different use requirements. When the support plate 310 is moved to the appropriate position, the fasteners 330 are used to fix the support plate 310, so as to ensure that the support plate 310 does not displace during the weighing process. The fasteners 330 can be designed in a form that is easy to manually operate or quickly adjusted by tools.

[0038] Further, the base 210 has a hollow groove 260, and the overhanging part 240 is located above the hollow groove 260.

[0039] Further, the base 210 is provided with two sliding grooves 270 matched with the support plate 310, and the two sliding grooves 270 are respectively located on both sides of the hollow groove 260. The support plate 310 can slide along one of the sliding grooves 270 and reach the other sliding groove 270. One of the sliding grooves 270 is provided with a mounting hole matched with the fastener 330.

[0040] The base 210 is provided with two sliding grooves 270, and the two sliding grooves 270 are respectively located on both sides of the hollow groove 260, providing a track for the movement of the support plate 310. The support plate 310 can slide along one of the sliding grooves 270 and finally reach the other sliding groove 270. This design allows the support plate 310 to be flexibly adjusted on the base 210 to adapt to the weighing sensor 220 in different positions. After the support plate 310 moves to the appropriate position, it can be fixed in any sliding groove 270 by the fastener 330, ensuring its stability during the movement of the weighing equipment. One of the sliding grooves 270 is provided with a mounting hole matched with the fastener 330, which is used to fix the support plate 310 and ensure that it does not shift during the movement of the weighing equipment.

[0041] In some embodiments, the base 210 is in the shape of a U.

[0042] The U-shaped base 210 is composed of two vertical side walls and a bottom connecting the two side walls, forming a U-shaped structure. This design leaves a hollow space in the center of the bottom of the base 210, providing enough space to install the sensor protection structure 300. The overhanging part 240 of the weighing sensor 220 is located above the hollow space of the U-shaped base 210, which can ensure the free movement of the sensor during weighing and reduce the influence of the base 210 on the sensor.

[0043] In some embodiments, the support plate 310 includes a bent portion 340 for the user to hold.

[0044] The bent portion 340 of the support plate 310 is a part of the support plate 310, designed to be folded or bent in shape to facilitate the user to hold, move and adjust the position of the support plate 310. The design of the bent portion 340 can be one-way or multi-way to adapt to different movement and adjustment needs. Through the bent portion 340, the support plate 310 can move along the sliding grooves 270 or the through groove 320 of the base 210 to reach the position where the weighing sensor 220 needs to be supported. The design of the bent portion 340 makes the support plate 310 more flexible during movement, which can adapt to different installation angles and positions.

[0045] In some embodiments, the cantilevered portion 240 is connected to a support beam 400 at an end distal from the fixed portion 230, and the support beam 400 is connected to the weighing conveyor line 120.

[0046] The cantilevered portion 240 of the load cell 220 is connected to a support beam 400 at an end distal from the fixed portion 230. This design can increase the stability of the load cell 220 and reduce vibrations or deformations caused by load changes during the weighing process. The connection method can be direct welding, bolt connection or other mechanical connection methods. The design of the support beam 400 helps to distribute the weighing load and reduce the pressure on the cantilevered portion 240 of the load cell 220, thereby improving the accuracy and reliability of the weighing. The support beam 400 can also serve as additional support for the weighing conveyor line 120, reducing sagging or deformation of the conveyor line under load.

[0047] Further, the sensor protection structure 300 further comprises a protective cover 350, which is arranged on the top of the load cell 220 and one end of the protective cover 350 abuts against the support beam 400.

[0048] The protective cover 350 is arranged on the top of the load cell 220 and covers the entire sensor to protect the sensor from the external environment. The material of the protective cover 350 can be metal, plastic or any other solid and durable material. One end of the protective cover 350 is designed to abut against the support beam 400, which can provide additional stability for the protective cover 350. The protective cover 350 can prevent dust and impurities from entering the load cell 220, reduce maintenance requirements and prolong the service life of the sensor. The protective cover 350 can also prevent moisture and other liquids from entering and protect the sensor from corrosion.
