Detailed Description

The following will explain in detail an elastic membrane cardboard packer of the present invention with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 6, as a preferred embodiment of the present invention, the stretch film cardboard packing machine includes a packing frame 1 and a transfer mechanism 2, and the transfer mechanism 2 is divided into a feeding transfer mechanism 21 and a discharging transfer mechanism 22. The packaging machine frame 1 is hollow to form a packaging space 3, the front part and the rear part are respectively connected with the conveying mechanism 2 in an open mode, one side connected with the discharging conveying mechanism 22 is provided with a hollow rotating wheel 11, and one side connected with the feeding conveying mechanism 21 is provided with a film guiding device 13 and a film cutting device 14.

The packing machine frame 1 is provided with fixing wheel rods 12 which are inwards facing and parallel to the rotating plane of the hollow rotating wheel 11 at the upper, lower, left and right sides of one side of the hollow rotating wheel 11. The ends of the four fixed wheel rods 12 are respectively provided with a fixed wheel 121 which extends towards the hollow rotating wheel 11 and the axial direction of the fixed wheel is parallel to the axial direction of the hollow rotating wheel 11. The four fixed wheels 121 are respectively in close contact with the inner circular wall of the hollow rotating wheel 11, so that the hollow rotating wheel 11 is scratched on the packaging machine frame 1.

Preferably, as shown in fig. 6, the fixed wheel 121 is provided with a flange 122 at an end facing the packing space 3 to prevent the hollow rotating wheel 11 from slipping off when rotating.

The groove arranged on the outer circumferential surface of the hollow rotating wheel 11 is a belt groove 113, the belt 112 is connected with the motor 111 and is sleeved in the belt groove 113, and the hollow rotating wheel 11 is controlled by the motor 111 to rotate. One side of the hollow rotating wheel 11 facing the packing space 3 is provided with a film mounting rod 114 vertical to the hollow rotating shaft, and an elastic film roll 115 is mounted on the film mounting rod 114. The roll of elastic film 115 is a roll of elastic film 115 having self-adhesiveness.

The film guide 13 and the film cutting device 14 are provided on a slider 151 mounted on the slide bar 15, the slider 151 being movable up and down along the slide bar 15. The film guide 13 is a cylindrical rod whose surface is a film-adhesive material. The plane of rotation of the film guide 13 is perpendicular to the plane of rotation of the hollow wheel 11. The film cutting device 14 includes a cutting blade 141 and a buffer block 142, the edge of the cutting blade 141 is serrated, and the buffer block 142 is a piece of elastic material disposed to abut against the lower side of the cutting blade 141.
