Description of reference numerals: the hot-pressing bonding device comprises an air inlet 1, a long straight line type hot-pressing bonding line 2, a short line section type hot-pressing bonding line 3, an arc-shaped hot-pressing bonding line A4, a main runner region 5, an auxiliary runner region 6, a cavity 7 and an arc-shaped hot-pressing bonding line B8.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
as shown in fig. 1, in the medical warming blanket, a cavity 7 communicated with an air inlet 1 is formed at the edges of an upper layer of non-woven fabric and a lower layer of non-woven fabric through hot pressing, two long straight hot-pressing bonding lines 2 are arranged on the warming blanket, a main flow channel region 5 is formed between the long straight hot-pressing bonding lines 2, an auxiliary flow channel region 6 is formed between the long straight hot-pressing bonding lines 2 and the upper edge and the lower edge of the cavity 7, and the main flow channel region 5 and the auxiliary flow channel region 6 are separated by the long straight hot-pressing bonding lines 2 and communicated at gaps at two ends; an arc hot-press bonding line A4 is arranged at the air inlet 1, an arc hot-press bonding line A4 is connected with the hot bonding lines at the upper edge and the lower edge of the cavity 7, and the concave surface of the arc hot-press bonding line A4 is right opposite to the main flow passage area 5 and the auxiliary flow passage area 6. An arc hot-press bonding line B8 is arranged at the position opposite to the concave surface of the arc hot-press bonding line A4, the convex surface of the arc hot-press bonding line B8 is opposite to the main flow channel region 5 and the auxiliary flow channel region 6, and the center line of the arc hot-press bonding line B8 is overlapped with the center line of the arc hot-press bonding line A4. A plurality of short line section type hot-press bonding lines 3 are arranged in the main runner area 5, in the embodiment, the short line section type hot-press bonding lines 3 are arranged in a parallel and staggered mode and are parallel to the long straight line type hot-press bonding line 2, at least one short line section type hot-press bonding line 3 is coincided with the central line of the air inlet 1, and the long straight line type hot-press bonding line 2 and the short line section type hot-press bonding line 3 are arranged at equal intervals.
