Buffering gas cushion machine

A buffering air cushion machine, comprising a frame (1), which is provided with a barrel, a guide rod combination, an inflation guide rod (4) and a heat-sealing cooling transmission module, wherein an angle between the heat-sealing cooling transmission module and a horizontal plane is 20-50 degrees;

• the guide rod combination comprises an upper coding film guide rod (31) and a lower coiling film guide rod (32);
• the inflation guide rod (4) is in a bent shape, a horizontal plane at which an inflation input end of the inflation guide rod (4) is located between an upper horizontal section of the upper coiling film guide rod (31) and a lower horizontal section of the lower coiling film guide rod (32);
• an output end of the inflation guide rod (4) is opposite to an inlet end of the heat-sealing cooling transmission module,
• wherein the heat-sealing cooling transmission module comprises an upper heating belt (51), a lower heating belt (52), an upper heating module (53), a lower heating module (54), an upper cooling module (55), a lower cooling module (56), a transmission wheel set (57), a first driving wheel (58), a second driving wheel (59), a first driving means (510) and a second driving means (511), wherein the upper heating belt (51) and the lower heating belt (52) are sleeved on the transmission wheel set (57), the upper heating belt (51) and the lower heating belt (52) are symmetrically distributed with respect to the output end of the inflation guide rod (4), and between the upper heating belt (51) and the lower heating belt (52) is formed a conveying path for a air cushion film;
• wherein the upper heating module (53), the upper cooling module (55) and the first driving wheel (58) are sequentially disposed in a conveying direction of the upper heating belt (51), and the lower heating module (54), the lower cooling module (56) and the second driving wheel (59) are sequentially disposed in a conveying direction of the lower heating belt (52);
• wherein the upper heating module (53) and the lower heating module (54) are symmetrically distributed with respect to the output end of the inflation guide rod (4), the upper cooling module (55) and the lower cooling module (56) are symmetrically distributed with respect to the output end of the inflation guide rod (4), and the first driving wheel (58) and the second driving wheel (59) are symmetrically distributed with respect to the output end of the inflation guide rod (4);
• wherein the second driving means (511) drives the first driving wheel (58) and the second driving wheel (59) to rotate, the first driving wheel (58) drives the upper heating belt (51) to move, the second driving wheel (59) drives the lower heating belt (52) to move, and the transmission wheel set (57) is rotatably connected to the frame (1),
• wherein the first driving means (510) drives by means of a rail mechanism the upper heating module (53) to reciprocate in a direction toward the lower heating module (54) and perform the clamping or expanding operation with the lower heating module (54), and
• wherein the heat-sealing cooling transmission module further comprises a driving mechanism which drives the upper cooling module (55) to reciprocate in a direction toward the lower heating module (54) and perform the clamping or expanding operation along with the lower heating module (54).
