[0002] A Tyvek head bag is a head bag made of a special packaging material, which is made of a spunbonded olefin material spun from countless fine polyethylene fibers. It has the characteristics of not being easy to deform, soft and smooth, light and tough, opacity, moisture-proof and water-resistant, and does not contain adhesives. It is suitable for packaging of Class II and Class III products with higher costs and risks, such as disposable medical devices like anesthesia packs and surgical packs.

[0003] In the prior art, due to the high cost of Tyvek materials, only part of the Tyvek materials are used to be spliced with a polyethylene plastic film to form the upper sheet when producing head bags. Affected by the unwinding positions of the Tyvek materials and the polyethylene plastic film, it is impossible to position them well during splicing, and misalignment is likely to occur, resulting in low heat-sealing quality between the two, insecure splicing, and inconvenience for the production of Tyvek head bags. Summary of the Invention

[0025] A feeding device of a Tyvek head bag making machine provided by an embodiment of the present utility model will now be described. Please refer to Figures 1 to 6, a feeding device for a Tyvek top bag making machine, including a base 1. A positioning component 2 is installed on the surface of the base 1. The positioning component 2 includes a fixed seat 201. The lower surface of the fixed seat 201 is fixedly connected to the upper surface of the base 1. A lead screw 202 is movably connected inside the fixed seat 201. One end of the lead screw 202 passes through the inside of the fixed seat 201 and extends to the outside of the fixed seat 201.

A clamping plate 205 is fixedly connected to the side surface of the movable plate 204. The side surfaces of the clamping plate 205 are respectively in contact with the outer surfaces of the lower roller 4 and the upper roller 6. The clamping plate 205 is clamped between the Tyvek material roll and the polyethylene plastic film roll, thus preventing dislocation between the Tyvek material roll and the polyethylene plastic film roll and facilitating the heat sealing between the Tyvek material roll and the polyethylene plastic film roll. An upper top plate 206 is fixedly connected to the surface of the base 1. An activity groove 207 is opened on the upper surface of the upper top plate 206.

One end of the upper roller 6 passes through the side surface of the base 1 and extends to the other side of the base 1. While the second motor 3 drives the lower roller 4 to rotate, the upper roller 6 is driven to rotate together through the lower gear 5 and the upper gear 7. Place the Tyvek material roll on the upper roller 6 and push it inward to the upper roller 6 so that the Tyvek material roll contacts the left side plate 208. Start the first motor 203. The output shaft of the first motor 203 drives the lead screw 202 to rotate, thereby driving the movable plate 204 to move and making the clamping plate 205 approach the Tyvek material roll, restricting the Tyvek material roll between the left side plate 208 and the clamping plate 205. Then place the polyethylene plastic film roll on the lower roller 4 and push it inward to the lower roller 4 so that the polyethylene plastic film roll contacts the side surface of the clamping plate 205. Place the right side plate 209 between the upper roller 6 and the lower roller 4. The positioning bolt 210 at the upper end of the right side plate 209 enters the activity groove 207, and then push the right side plate 209 until it contacts the polyethylene plastic film roll.Turn the positioning bolt 210 to fix the right side plate 209 to the upper top plate 206, and restrict the polyethylene plastic film roll between the clamping plate 205 and the right side plate 209.
