DETAILED DESCRIPTION

[0031] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0032] like Figures 1 to 5 As shown, this embodiment provides a test paper cutting and separation device, comprising:

[0033] A machine base 11, the machine base 11 has an upper support plate 12 and a lower support plate 13, and the upper support plate 12 is located above the lower support plate 13;

[0034] A driving member 14, the driving member 14 is mounted on the upper support plate 12, and the driving member 14 has an output end moving in a vertical direction;

[0035] An upper tool assembly 15, which is arranged on the output end of the driving member 14 through a mounting plate 16, and a first blowing device 17 is installed on the upper tool assembly 15;

[0036] The lower tool assembly 18 is mounted on the lower support plate 13 via a support platform 19 , and a second blowing device 20 is mounted on the lower tool assembly 18 .

[0037] The technical effect of this solution is that after the upper cutter assembly 15 and the lower cutter assembly 18 cut the test paper, the first blowing device 17 blows air to the upper surface of the test paper, and the flowing gas can blow the cut test strip off. Among them, the second blowing device 20 blows up the edge of the test paper to be cut, so that the lower cutter 21 on the lower cutter assembly 18 can be separated from the test paper.

[0038] Furthermore, the driving member 14 is a pneumatic cylinder or a hydraulic cylinder.

[0039] Furthermore, an opening is provided on the support platform 19 , and the lower tool assembly 15 is located in the opening. The lower tool assembly 15 is fixed on the support arm 42 of the support platform 19 .

[0040] Furthermore, the second blowing device 20 is located on one side of the feeding direction of the lower cutter 21 of the lower cutter assembly 18. It is used to blow up the test paper to be processed in the feeding direction to avoid adhesion between the test paper and the lower cutter.

[0041] Furthermore, the first blowing device 17 is located on the side of the upper tool assembly 15 that is opposite to the feeding direction, that is, the first blowing device 17 is located on the discharge side of the upper tool assembly 15, so as to blow off the cut test paper.

[0042] As an implementation of this embodiment, the upper tool assembly 15 has an upper cutter 22 and an upper limit block 23 , and an escape groove 24 is left between the upper limit block 23 and the upper cutter 22 , and the escape groove 24 is used to accommodate the lower cutter 21 .

[0043] The technical effect of this solution is that when the upper cutter 22 and the lower cutter 21 cut the test paper, the lower cutter 21 will enter the avoidance groove 24 of the upper cutter assembly 15, further hindering the contact between the lower cutter 21 and the test paper, and reducing the adhesion between the test paper and the lower cutter 21. On the other hand, the upper cutter 22 is in contact with the cut test paper, and under the action of the first blowing device 17, the test paper adhering to the upper cutter 22 can be effectively blown off.

[0044] As an implementation of this embodiment, the lower tool assembly 18 also has a lower limit block 25, which is located on one side of the feeding direction of the lower cutter 21. The upper end of the lower limit block 25 has a flat portion 26 and is used to support the edge of the test paper.

[0045] Further, the first blowing device 17 is mounted on the upper tool seat 27 of the upper tool assembly 15, and the first blowing device 17 has a plurality of first air nozzles 28 opening downward. The second blowing device 20 is mounted on the lower tool seat 29 of the lower tool assembly 18, and the second blowing device 20 has a plurality of second air nozzles 30 opening upward.

[0046] The air inlet pipe, the solenoid valve and the air pump on the first air blowing device 17 and the second air blowing device 20 are not shown in the drawings.

[0047] As an implementation of this embodiment, a guide member 31 is fixed on the mounting plate 16 , and the guide member 31 can be slidably installed in the mounting opening of the upper support plate 12 along the vertical direction.

[0048] Among them, the guide member 31 is L-shaped, and the guide member 31 has a vertical arm 40 and a horizontal arm 41. The vertical arm 40 is provided with a curved surface portion 35, and the vertical arm 40 can be slidably arranged in the mounting opening of the upper support plate 12 along the vertical direction, and the horizontal arm 41 is fixedly connected to the mounting plate 16.

[0049] As an implementation mode of this embodiment, an automatic switch component is also included, and the automatic switch component is used to control the operation of the first blowing device 17 and the second blowing device 20.

[0050] The switch assembly includes:

[0051] A micro switch 32 is installed on the upper support plate 12 through a support 33 ; the micro switch 32 is used to control the operation of the first blowing device 17 and the second blowing device 20 .

[0052] The reciprocating mechanism is installed between the upper support plate 12 and the lower support plate 13 through the vertical plate 38. One end of the reciprocating mechanism is used to squeeze the micro switch 32. The other end of the reciprocating mechanism is installed with a rotating wheel 34. The circumferential surface of the rotating wheel 34 is used to squeeze the curved surface 35 of the guide member 31.

[0053] Further, the reciprocating mechanism comprises:

[0054] A guide rod 37, the guide rod 37 is slidably mounted horizontally on the vertical plate 38;

[0055] A rotating wheel seat 36, which is mounted on the end of the guide rod 37 and is used to mount the rotating wheel 34;

[0056] Spring 39 , spring 39 is sleeved on the guide rod 37 , and spring 39 is located between the rotating wheel seat 36 and the vertical plate 38 .

[0057] When the guide member 31 moves downward, the curved surface portion 35 on the vertical arm 40 squeezes the rotating wheel 34. At this time, the guide rod 37 squeezes the trigger portion of the micro switch 32, and the micro switch 32 is turned on. At this time, the first blowing device 17 and the second blowing device 20 work.

[0058] Among them, the micro switch 32 is a common device, and the specific structure and working principle of the micro switch 32 are not described in detail.

[0059] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
