[0033] The embodiments of the present application will be described in detail below with reference to the drawings. Embodiment 1

[0034] As shown in the drawing, a valve core strength detection device, comprising a vibration feeder 1 and a base 2. Figures 1-8 The top of the base 2 is fixedly connected with two symmetrical guide plates 4 through a support frame, the end of the guide plate 4 is fixedly connected with the discharge port of the vibration feeder 1, the base 2 is provided with a positioning assembly 3 for supporting the valve core a, the top surface of the mounting frame 5 is provided with a detection assembly 6, the positioning assembly 3 comprises a push plate 12 and an electric push rod two 13, the electric push rod two 13 is fixedly connected with the inner wall of the base 2 through bolts, the telescopic end of the electric push rod two 13 penetrates the base 2 and is fixedly connected with the bottom of the push plate 12, and a plurality of positioning cylinders 11 are fixedly installed on the top of the push plate 12. The vibration feeder 1 is prior art, and its working principle will not be described here.

[0035]

[0036] ​The valve core a that needs to be tested for strength is poured into the vibrating feeder 1. The vibrating feeder 1 conveys the valve core a vertically to the guide plate 4, and then guides it to the positioning component 3. At this time, the electric push rod 13 is activated to drive the push plate 12 to move all the positioning cylinders 11 upward until the bottom upper surface of the positioning cylinder 11 contacts the bottom of the valve core a. Then the testing component 6 is moved downward. When the testing component 6 contacts the top of the valve core a, the testing component 6 continues to descend. The testing component 6 is used to test the strength of multiple valve cores a at one time.

[0037] This device, by setting up a vibrating feeder 1 and a guide plate 4, can continuously transport valve core a to the detection component 6 for detection by the cooperation of the vibrating feeder 1 and the guide plate 4. Multiple positioning cylinders 11 can be used to position and fix the valve core a when it reaches the detection component 6, thereby realizing batch detection and improving detection efficiency.

[0038] like Figure 2 , 3 As shown, an electric push rod 7 is fixed to the outer wall of the mounting frame 5 by bolts. The telescopic end of the electric push rod 7 passes through the mounting frame 5 and is fixedly connected to a connecting plate 8. Multiple spaced partition plates 9 of different lengths are fixedly connected to the other side of the connecting plate 8. The partition plates 9 are slidably fitted to the inner wall of the guide plate 4 and have pointed ends.

[0039] A photoelectric gate 10 is fixedly installed on the top of the guide plate 4. The electric push rod 7, the photoelectric gate 10 and the electric push rod 13 are electrically connected to the same central processing unit.

[0040] When valve core a passes through photoelectric gate 10, photoelectric gate 10 collects the number of passages and transmits the signal to the central processing unit. The central processing unit first activates electric push rod 7 to push connecting plate 8 and multiple partition plates 9 to move synchronously. When the longest partition plate 9 is inserted into the gap between two adjacent valve cores a, it separates the two valve cores a. As electric push rod 7 and connecting plate 8 continue to push, the remaining partition plates 9 are pushed forward in sequence until multiple valve cores a are separated. Then, the central processing unit activates electric push rod 13 to drive push plate 12 to drive all positioning cylinders 11 to rise. The positioning cylinders 11 support the valve cores a. Then, the detection component 6 is moved down to detect the valve cores a.

[0041] This device, by setting multiple spacer plates 9 of different lengths at intervals, can gradually separate multiple valve cores a, increase the distance between valve cores a, and avoid the valve cores a from sticking together and affecting the test results, thereby improving the accuracy of the device's test.
