The punching water absorption pad 2 is of a multilayer structure, the uppermost layer is a water-resisting punching film 21, the lower layer of the water-resisting punching film 21 is a water absorption material layer 22, the water-resisting punching film 21 and the water absorption material layer 22 are combined together up and down, and a layer of water-resisting punching film 21 can be further combined below the water absorption material layer 22 according to actual needs; the water-proof punching film 21 is a PE punching film; the aperture of the permeable holes of the PE perforated membrane is 1-2mm, and the center distance between adjacent permeable holes is 4-6 mm.
The blood collecting tank 11 in be provided with the film and support the muscle position, the bottom surface at the absorbent pad 2 that punches a hole is supported to the film support muscle position, prevents to punch a hole the middle undercut of absorbent pad 2.
The blood collection tank 11 is rectangular, the thin film supporting rib positions comprise a rectangular outer frame 12 and a plurality of T-shaped supporting rib positions 13 which are positioned in the outer frame, a ring groove 14 is formed between the outer frame 12 and the inner wall of the blood collection tank, the T-shaped supporting rib positions 13 comprise transverse ribs and longitudinal ribs which are perpendicular to each other, one ends of the longitudinal ribs are connected to the middle parts of the transverse ribs, the other ends of the longitudinal ribs are connected with the transverse parts of the rectangular outer frame 2, the longitudinal ribs are perpendicular to the transverse parts of the rectangular outer frame 2, the T-shaped supporting rib positions 13 are divided into two groups, the longitudinal ribs of the two groups of T-shaped supporting rib positions 13 are respectively connected with the two transverse parts of the rectangular outer frame 2, the two groups of T-shaped supporting rib positions 13 are arranged in a staggered mode, an arc-shaped flow passage 15 is formed in the outer frame 12, two notches 16 are formed in the middle of the longitudinal part of the outer frame 12, and the notches 16 are communicated with the ring groove 14 and the arc-shaped flow passage 15; the T-shaped supporting rib positions 13 are arranged in a staggered mode, so that the punched water absorption pad 2 is uniformly supported, meanwhile, the arched flow channel 15 is formed inside, the annular groove 14 and the arched flow channel 15 are communicated through the notch 16, the internal space of the blood collection tank 11 is communicated, and the phenomenon that the local space is full of blood and overflows is avoided.

The blood water collecting tank at the bottom of the box body reduces the contact time with food; blood water collecting vat accounts for the great of box body bottom, make the bottom have great water storage space, it has the hole layer of dashing of the upper strata contact food to punch a hole, the following is the water-absorbing material layer, because water has tension, if the hole layer of dashing above only, can't smoothly pass through tiny punching a hole, the water on upper strata is actively gone to the layer of only absorbing a hole below, just can produce suction, the continuous absorption in water source that produces above, simultaneously the water proof film of punching a hole plays isolation food and water-absorbing material layer, avoid the water-absorbing material layer direct and food surface layer contact to inhale the moisture on food surface futilely.
The invention also carries out selection tests on the aperture size and the center distance between the water-proof punching films 21 of the punching water absorption pad 2:
in the test, the sizes of the punching absorbent pads 2 are unified to 160mm x 70mm, and the absorbent capacity is 30 ml; all the products after ultrasonic heat sealing are used in the testing process.
Firstly, under the condition that the center distance is 6mm, testing the water absorption capacity and the water locking capacity according to the pore size:
1.1, the aperture phi is 1mm, 30ml of water is poured, the water absorption time is 35 seconds, after water absorption, the water absorption device is transversely inclined at 60 degrees and placed for 1 hour, and no water seeps out of the surface.
1.2, the aperture phi is 1.5mm, 30ml of water is poured, the water absorption time is 32 seconds, after water absorption, the water absorption device is transversely inclined at 60 degrees and placed for 1 hour, and no water seeps out of the surface.
1.3, the aperture phi is 2mm, 30ml of water is poured, the water absorption time is 28 seconds, after water absorption, the water is transversely inclined for 1 hour at 60 degrees, and the surface has water seepage.
From the above 3 tests, it was found that when the pore diameter was 1.5mm, the water absorption rate was high and the water leakage could be prevented.
Secondly, under the condition that the pore diameter is 1.5mm, the water absorption capacity is tested according to the center distance:
2.1 mm apart from the center, 30ml of water was poured in, and the time taken for water absorption was 27 seconds.
2.2 mm from the center, and 30ml of water is poured into the water storage tank, and the water absorption time is 30 seconds.
2.3 mm from the center, and 30ml of water is poured into the water storage tank, and the water absorption time is 32 seconds.
2.4, center distance 7mm, and 30ml of water is poured, and the water absorption time is 38 seconds.
From the above 4 tests, it can be seen that the longer the distance between the centers, the longer the time period for absorbing water, but the too close distance between the centers makes the water-absorbing pad 2 absorb water too strongly, and does not utilize the surface of the food to retain moisture.
Therefore, in summary, we propose to select a pore size of 1-2mm, with 1.5mm being the most preferred solution and a center-to-center distance of 4-6mm being the most preferred option.
In addition, the punching absorbent pad structure is tested by different materials and different structures:
the water absorption capacity of the punching water absorption pads selected in the experiment is unified to be 30ml, the surface aperture is 1.5mm, and the center distance is 5 mm; all the products after ultrasonic heat sealing are used in the testing process.
