[0023] According to this specific embodiment, the pressure-bearing mechanism 104 is fixedly connected to the transmission mechanism 101, the clamping mechanism 102 is fixedly connected to the pressure-bearing mechanism 104, the sleeve 109 is rotatably connected to the cross bar 108, one end of the cross bar 108 is fixedly connected to the toggle air rod 107, the upper end of the toggle air rod 107 is fixedly connected to the output end of the toggle cylinder 106, the toggle cylinder 106 is fixedly connected to the side plate 105, the side plate 105 is fixedly connected to the pressure-bearing mechanism 104, the guide belt 115 is sleeved on the two guide wheels 114, the two guide wheels 114 are respectively fixedly connected to the corresponding conveying rollers 111, the motor 113 is fixedly connected to the frame 110, and each of the conveying rollers 111 is rotatably connected to the frame 110 Dynamic connection, one end of one of the conveying rollers 111 is fixedly connected to the output end of the motor 113, the pressing plate 118 is fixedly connected to the pressing gas rod 117, the upper end of the pressing gas rod 117 is fixedly connected to the output end of the pressing cylinder 116, the pressing cylinder 116 is fixedly connected to the pressure mechanism 104, and the two inclined plates 120 are fixedly connected to the pressure frame 119. The currently arranged toggle cylinder 106 drives the toggle gas rod 107 to control the cross bar 108 and the tube sleeve 109 to move on the inner side of the pressure mechanism 104, so as to quickly evacuate the pressed mattress and facilitate the subsequent transfer of the mattress. This design solves the problem that the mattress is easy to stick to the mounting frame after being squeezed, which is not convenient to push out and needs to be taken out manually with tools, which is time-consuming and labor-intensive.
