Description
Technical Field
The utility model belongs to the technical field of the sensor, concretely relates to weighing sensor for garbage classification.
Background
At present, the requirements on classification and throwing processes of garbage throwing are higher and higher, and the garbage throwing device is developed towards a fine direction. The weighing sensor is important, the weight of garbage can be continuously measured even in a background state, the weighing sensor is used as an excellent weighing device, the weighing sensor is different from common devices, and the weighing sensor converts an object weight signal into an electric signal and transmits the weight of the object through the electric signal. The basic principle is that the elastic body generates elastic deformation under the action of external force, so that the resistance strain gauge adhered to the strain area of the elastic body generates deformation along with the elastic deformation; after the resistance strain gauge deforms, the resistance value of the resistance strain gauge changes (such as increases or decreases), and the resistance change is converted into an electric signal (such as voltage or current) through a corresponding measuring circuit, so that the process of converting the external force into the electric signal is completed. However, the weighing sensor in the prior art has the problem of insufficient sensitivity.
The utility model discloses a chinese utility model patent of application number 2019208880239 discloses a high accuracy weighing sensor, including the weighing sensor body, be equipped with the weighing sensor support on the weighing sensor body, connecting cable, the indent, the metallic shield net, the title platform, the fixed screw hole, the metallic resistance silk, receiving sensor, be equipped with the indent at the inside central authorities of weighing sensor support of weighing sensor body, the inside of indent is gone up the jade and is hugged closely with the bottom surface has the metallic resistance silk, the metallic resistance silk forms a return circuit and is connected with receiving sensor, connect sensor and connecting cable to be connected, timely convert received signal of telecommunication transmission into digital signal, this metallic resistance silk can stretch out and draw back according to the proportion after receiving tensile, make its resistance change, measure weight signal through the change of metallic resistance silk, thereby calculate the gravity size.
Above-mentioned patent promotes the precision of sensor through addding the resistance wire, but this scheme still can take place signal transmission through indent emergence deformation in essence, if the sensitivity of indent is not enough, then can't be from the precision of sensor by a wide margin in essence. Therefore, the above patent still fails to essentially solve the problem of insufficient sensitivity of the load cell in the prior art.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a weighing sensor for garbage classification, including the elastomer, the elastomer includes first connecting portion and second connecting portion, be equipped with strain portion between first connecting portion and the second connecting portion, first strain slotted hole and second strain slotted hole have been seted up to strain portion's both sides, strain slotted hole and second strain slotted hole between be equipped with the wall thickness, the middle width of first strain slotted hole is greater than the middle width of second strain slotted hole.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Example 1
As shown in fig. 1-3, a weighing sensor for garbage classification comprises an elastic body, wherein the elastic body comprises a first connecting portion 1 and a second connecting portion 2, a strain portion 3 is arranged between the first connecting portion 1 and the second connecting portion 2, first strain slots 4 and second strain slots 5 are formed in two sides of the strain portion 3, a wall thickness 6 is arranged between the strain slots and the second strain slots 5, connecting bolt holes 7 are formed in the wall thickness 6, the connecting bolt holes 7 are used for strain gauges (not shown) arranged in the two strain slots, and the middle width of the first strain slot 4 is greater than the middle width of the second strain slot 5. Preferably, both sides at first strain slot 4 are equipped with bellied circular arc structure 8, both sides are the straining beam structure about first strain slot 4, bellied circular arc structure 8 aim at weakens the thickness of lower part on the first strain slot 4, thereby increase the local stress level, improve the sensitivity of sensor, and adopt circular arc structure 8 can avoid stress concentration excessively, both ends weaken in comparison, the unilateral weakens has been adopted in this embodiment, the unilateral weakens and both can guarantee that the local stress level increases, can keep higher intensity and rigidity on the whole again, vertically be equipped with first bolt hole 9 and second bolt hole 10 on first connecting portion 1, transversely be equipped with fourth bolt hole 12 on first connecting portion 1. The first connecting portion 1 is the load end, and the first connecting portion 1 is connected with the load portion through first bolt hole 9 and second bolt hole 10 and fourth bolt hole 12, is equipped with third bolt hole 11 on the second connecting portion 2, and 2 stiff ends of second connecting portion are connected with M12 high strength bolt on the third bolt hole 11, and second connecting portion 2 passes through third bolt hole 11 and fixed part fixed connection.
In the present embodiment, when using, first connecting portion 1 is connected with the load end, and second connecting portion 2 is connected with the fixed equipment, and it should be noted that although fig. 2 and 3 are the structure diagrams in the vertical state, when using, the elastic body should be in the horizontal state, and first connecting portion 1 is deformed after receiving the acting force, and the deformation takes place in the upper and lower both sides of first strain slot 4 and second strain slot 5, and its internal strain gauge also takes place to be deformed along with it, and its resistance value also can change. The resistance change is converted into an electrical signal such as voltage or current by a corresponding measuring circuit, thereby completing the process of converting the external force into the electrical signal.
