The feeding mechanism is used for conveying the test paper 200 to be cut to the cutting mechanism 20; the cutting mechanism 20 is configured to cut the test strip 200 to obtain an independent test strip 201; the pushing block 30 is used for leveling the cut test strip 201, so that the blanking mechanism 40 can convey the leveled test strip 201 backwards.

The feeding mechanism comprises a supporting seat 11, a supporting plate 12 and a third driving device 13, wherein the supporting seat 11 and the supporting plate 12 are located on the same horizontal plane, and the test paper 200 to be cut is arranged on the supporting plate 12 and the supporting seat 11 and at least partially extends out of the supporting seat 11 for cutting.

The third driving device 13 is disposed on the supporting plate 12, and is configured to push the test paper 200 to be cut to move toward the supporting seat 11.

Referring to fig. 3 in conjunction with fig. 1-2, the cutting mechanism 20 is disposed behind the supporting base 11 and is configured to cut the test paper 200 extending out of the supporting base 11.

The cutting mechanism 20 includes an upper cutter 21 and a lower cutter 22. The lower cutter 22 is fixedly arranged at the tail end of the support seat 11 and is flush with the upper surface of the support seat 11. At least a part of the test paper 200 extending out of the supporting seat 11 is located above the lower cutter 22, so that the upper cutter 21 cooperates with the lower cutter 22 to cut.

Referring to fig. 4 in combination with fig. 1 to 3, a groove 111 for passing the upper cutter 21 and the push block 30 is disposed on the support seat 11 along the moving direction of the upper cutter 21, and the lower cutter 22 is disposed outside the groove 111.

When the first driving device 25 drives the eccentric 251 to move in the guide groove 241, the first mounting seat 23 and the second mounting seat 24 reciprocate up and down along with the movement of the eccentric 251.

Specifically, when the first driving device 25 drives the eccentric 251 to move to the lowest position, the upper cutter 21 at least partially penetrates through the groove 111 and cooperates with the lower cutter 22 to complete one-time cutting of the test strip 200 and obtain the test strip 201.

When the first driving device 25 drives the eccentric 251 to move to the highest position, the push block 30 at least partially penetrates through and extends out of the groove 111 to level the cut test strip 201.

When the upper cutter 21 is located above the supporting seat 11 and the pushing block 30 does not extend out of the groove 111, the third driving device 13 drives the test paper 200 to be cut to move forward and extend at least part of the test paper 200 out of the supporting seat 11 again and locate on the lower cutter 22.

At this time, the first driving device 25 continues to drive the upper cutter 21 to move downwards to cooperate with the lower cutter 22 to complete cutting of the test paper 200 again.

In other embodiments, the second mounting seat 24 includes a first seat 243 and a second seat 244, the first seat 243 and the second seat 244 are both connected to the guide rod 26, the first seat 243 is disposed above the second seat 244, the push block 30 is disposed on the first seat 243, and the guide groove 241 is disposed on the second seat 244.

Further, the second mounting seat 24 is detachably connected to the guide rod 26, so that the position of the second mounting seat 24 relative to the first mounting seat 23 can be adjusted, so that an operator can adjust the distance between the push block 30 and the upper cutter 21 according to actual production requirements, and when the upper cutter 21 moves to the highest position, the push block 30 at least partially extends out of the groove 111 to level the test strip 201 which is just cut.

Further, a second mounting groove 242 is formed in the second mounting seat 24, and the push block 30 is disposed in the second mounting groove 242.

Preferably, one end of the push block 30 close to the upper cutter 21 is a guiding slope (not shown), and when the push block 30 levels the test paper 200, the test paper 201 can be guided in advance through the guiding slope, so that the push block 30 levels the test paper 201 more smoothly.

Further, two limit blocks 113 are arranged on the support base 11, and the two limit blocks 113 are arranged oppositely and used for limiting the test paper 200 to be cut.

The first limiting surfaces 1131 of the two limiting blocks 113 are oppositely disposed and limited on opposite sides of the test paper 200, and the second limiting surfaces 1132 of the two limiting blocks 113 are limited on the surface of the test paper 200.

So that the test paper 200 to be cut is more accurately conveyed forward by the third driving means 13.

Referring to fig. 5 in combination with fig. 4, the blanking mechanism 40 includes a feeding plate 41, a pushing plate 42 and a second driving device 43, and the feeding plate 41 is disposed outside the lower cutter 22 and is used for conveying the cut test strip 201.

The feeding plate 41 has a receiving slot 411 and a guiding slot 412, the receiving slot 411 and the guiding slot 412 are in T-shaped communication, the cut test paper 200 is leveled by the pushing block 30 and then sequentially reaches the guiding slot 412 through the receiving slot 411, and the pushing plate 42 is driven by the second driving device 43 to reciprocate in the guiding slot 412 to feed the cut test paper 201 backwards.

Specifically, the second driving device 43 is connected to a side surface of the feeding plate 41, the pushing plate 42 includes a pushing portion 421 and a connecting portion 422, the connecting portion 422 is connected to an output end of the second driving device 43, the pushing portion 421 extends into the material guiding groove 412, and moves along the material guiding groove 412 under the driving of the second driving device 43 to convey the cut test paper 201 backwards.

In one embodiment, an opening 4121 is formed at one end of the material guiding groove 412, and the second driving device 43 drives the push plate 42 to push the test strip 201 to be always delivered toward the opening 4121.

Specifically, in the present embodiment, the second driving device 43 has an initial position and an operating position.

When the second driving device 43 is located at the initial position, the push plate 42 is located at an end of the material guiding groove 412 far away from the opening 4121, and the push plate 42 does not extend beyond the material receiving groove 411.

When the cut and foremost test strip 201 reaches the guide chute 412, the second driving device 43 drives the push plate 42 to move in the guide chute 412 toward the opening 4121, so as to deliver the test strip 201 to the opening 4121, and at this time, the second driving device 43 reaches the working position.

After the second driving device 43 reaches the working position, the blanking of the test strip 201 is completed.

At this time, the second driving device 43 drives the push plate 42 to return to the initial position, and when the next cut and foremost test strip 201 reaches the material guiding groove 412, the second driving device 43 drives the push plate 42 to move in the material guiding groove 412 toward the opening 4121 to the working position again, thereby completing the transportation of the test strip 201.
