Technical Field

[0001] The utility model belongs to the technical field of online checkweighing machines, and in particular relates to an online checkweighing machine with a protection function. Background Art

[0002] Online checkweigher, also known as weight detector, weight sorter, automatic checkweigher, weight sorter, is a device that can realize high-speed and high-precision weight detection and automatically sort out underweight or overweight products under dynamic conditions of production lines, thereby greatly improving product quality and optimizing production processes, thereby controlling costs, eliminating waste, and increasing profits. It can be used to detect all products on the production line and fully display production data such as production quantity, batch tracking, total weight, effective weight, and rejection weight.

[0003] However, a common problem in the use of existing online checkweighers is that when items fall from a height into a collection box after completing the weight test, due to the lack of effective buffering measures, the items may be damaged due to excessive impact force, which not only affects the final quality of the product, but may also cause unnecessary economic losses. The traditional approach is to simply place a collection box on one side of the checkweigher. Although this achieves the basic collection function, it fails to effectively solve the problem of damage caused by impact.

[0004] Therefore, it is necessary to provide an online checkweigher with a protection function. Utility Model Content

[0005] The utility model provides an online checkweigher with a protective function, aiming to solve the problem that during use of the existing online checkweigher proposed in the background art, due to the lack of buffering measures for the collection box, the items after weight detection are easily damaged when entering the collection box.

[0007] Preferably, the driving mechanism includes: a dual-axis motor fixedly mounted on the base plate, with rotating shafts fixedly mounted on both output shafts of the dual-axis motor; two first bevel gears fixedly mounted on the two rotating shafts respectively; two second bevel gears fixedly sleeved on the two screws respectively, and the two second bevel gears are respectively meshed with the two first bevel gears.

[0008] Preferably, a plurality of limit rods are fixedly mounted on the bottom of the placement plate, the plurality of limit rods are all slidably connected to the support plate, and baffles are fixedly mounted on the bottom ends of the plurality of limit rods.

[0009] Preferably, an anti-skid pad is fixedly mounted on the inner wall of the bottom of the groove, and the anti-skid pad is arranged in a rectangular shape.

[0010] Preferably, two support blocks are fixedly mounted on the top of the base plate, and the two support blocks are rotatably connected to the two rotating shafts respectively.

[0011] Preferably, a plurality of gaskets are fixedly mounted on the bottom of the base plate, and the plurality of gaskets are all made of rubber material.

[0012] Preferably, the two screw rods are both made of stainless steel, and circular plates are fixedly mounted on the top ends of the two screw rods.

[0013] Compared with the related art, the online checkweigher with protection function provided by the utility model has the following beneficial effects:

[0014] Compared with the prior art, the online weighing machine with a protective function provided by the present invention can drive the two screws to rotate through a driving mechanism. The rotation of the two screws can adjust the use height of the support plate and the placement plate, and then the collection boxes of different heights can be adjusted to the optimal use position, and the adjustment is relatively convenient. After the adjustment is completed, the items to be inspected are placed on the conveyor belt of the online weighing machine body, so that the online weighing machine body can also convey the items during the process of detecting the weight of the items. After the weight detection is completed, the items will fall into the collection box from one side. Through the coordinated use of multiple springs and multiple damping pads, a good buffering effect can be achieved on the collection box, which can effectively prevent the items from being damaged during the collection process, and is not easy to affect the final quality of the product. The use effect is better, and multiple rubber gaskets can be used to increase the friction between the bottom plate and the ground, so that the equipment can be stably placed on the ground for use, and multiple limit rods can be used to improve the stability of the placement plate during use, and no skew will occur.
