DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0017] like Figure 1 , 2As shown, a semi-automatic film sealing machine for bearings of this embodiment comprises a frame 1 formed by a base 11, a top plate 12 and four guide pillars 13 fixedly connected to each other; a lower supporting plate 2 whose four corners are fixedly connected to the guide pillars 13 is arranged above the base 11; an upper pressing plate 3 whose four corners are slidably connected to the guide pillars 13 is arranged above the lower supporting plate 2; the top plate 12 is provided with a cylinder for driving the upper pressing plate 3 to rise and fall; soldering iron rings 4 for welding plastic sheets are arranged on the opposite surfaces of the lower supporting plate 2 and the upper pressing plate 3, a heating plate 5 is arranged inside the soldering iron ring 4, and two pieces of plastic sheets 8 are horizontally suspended between the upper supporting plate 2 and the upper pressing plate 3.

[0018] During operation, workers place the bearing to be packaged on the lower plastic sheet 8 between the two plastic sheets 8, and then operate the cylinder to drive the upper pressing plate 3 downward, so that the upper and lower soldering iron rings 4 are pressed against each other, and the high temperature of the soldering iron ring 4 is used to melt the plastic sheet 8, so that the overlapping parts of the two plastic sheets 8 around the bearing are welded together, thereby forming a bag-type packaged bearing and sealing it.

[0019] In order to better weld the plastic sheet 8, the surface of the soldering iron ring 4 used for welding is provided with at least three concentric circles of welding teeth 41, and the tops of the welding teeth 41 are rounded; in this way, the welding teeth 41 of the upper and lower soldering iron rings 4 contact each other, and because the contact area is smaller, it is easier to weld the overlapping plastic sheet 8 between the two.

[0020] In order to facilitate the separation of the packaging bag after the bearing is packaged from the entire plastic sheet 8, a circle of fuse teeth 42 is provided on the outermost side of the surface of the soldering iron ring 4 used for welding. The top of the fuse teeth 42 is a sharp angle, and the height of the fuse teeth 42 is equal to that of the welding teeth 41.

[0021] In order to facilitate the automatic blanking of the packaged bearings, the center of the lower support plate 2 is a through hole that can accommodate the bearings, and the center of the upper pressing plate 3 is a blind hole that can accommodate the bearings. A blanking block 6 and a spring 7 with two ends abutting against the blanking block 6 and the top of the upper pressing plate 3 are slidably connected in the central blind hole of the upper pressing plate 3; the bottom surface of the blanking block 6 is flush with the surface of the soldering iron ring 4 located on the upper pressing plate 3. During operation, when the upper pressing plate 3 moves downward, the blanking block 6 first abuts against the bearing, causing the spring 7 to compress, and then the upper and lower soldering iron rings 4 are attached to weld and fuse the plastic cloth 8. When the upper pressing plate 3 is about to move upward, the two soldering iron rings 4 are separated and no longer clamp the plastic cloth 8. At this time, the bearing packaging bag is completely separated from the plastic cloth 8 by the downward squeezing force of the blanking block 6, and falls from the through hole of the lower support plate 2 under the action of gravity.

[0022] In order to achieve continuous and rapid production, the present embodiment further provides a lower feed roller 81 and an upper feed roller 82 for supplying the plastic sheet 8, and a lower waste roller 83 and an upper waste roller 84 for recycling the plastic sheet 8, and the roller axes of the lower waste roller 83 and the upper waste roller 84 are parallel and rotate in opposite directions relative to each other through gear transmission, and the lower waste roller 83 and the upper waste roller 84 can be driven by a motor to rotate intermittently. When a bearing is packaged, the lower waste roller 83 and the upper waste roller 84 can be rotated to a certain angle through foot control, program control, or mechanical control, thereby pulling the upper and lower layers of the plastic sheet 8 to move one station to the right for the next packaging.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, and for the convenience of describing the technical solution, the front, rear, left, right, top, middle, and bottom directions adopted are based on the settings in the accompanying drawings, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
