Description

Technical Field

[0001] The utility model belongs to the technical field of surgical gown production equipment, in particular to a hot-melt connection equipment for non-woven surgical gowns. Background Art

[0002] Non-woven surgical gowns are one of the most important protective equipment for medical staff during surgery. They are made of multiple pieces of non-woven fabrics connected by hot-melt. Non-woven surgical gowns need to be produced using hot-melt connection equipment. The hot-melt equipment includes a driving mechanism, a hot-melt roller and a material table. The two pieces of non-woven surgical gowns that need to be hot-melted are spliced ​​together and placed on the material table, and then the equipment is started. The hot-melt roller is driven by the power mechanism to roll on the interface position of the non-woven surgical gown that needs to be hot-melted to achieve the hot-melt effect.

[0003] A Chinese patent application (or patent) with publication number CN217021461U discloses a hot melt adhesive welding machine for non-woven fabric strips for surgical gowns, including a machine body, the right end of the machine body is fixedly connected to a workbench through a second fixed column, the middle rear side of the bottom end of the workbench is fixedly connected to a bracket, the middle front side of the right end of the machine body is rotatably connected to uniformly distributed pressure rollers, the lower part of the pressure rollers are all provided with rollers, the middle of the rollers are all penetrated and fixedly connected with a rotating shaft, the outer peripheries of the left and right ends of the rotating shaft are fixedly connected with bearings, and the outer peripheries of the bearings are fixedly connected inside the fixed block. In the utility model, when the stepper motor is working, it can drive the threaded plate to move up and down on the threaded rod, thereby driving the fixed block fixed to the connecting block to rise and fall, so that the distance between the roller and the pressure roller inside the fixed block can be adjusted, which is conducive to gluing different fabrics, and the fabrics can be pressed during gluing, so that the gluing effect is better.

[0004] The above-mentioned hot-melt adhesive welding machine for non-woven fabric strips for surgical gowns has a roller embedded in its workbench, and the non-woven surgical gown material is pressed and hot-melted by the cooperation of the roller and the pressure roller. However, it can only hot-melt the sheet-shaped non-woven surgical gown material, and cannot hot-melt the non-woven fabric material in cylindrical and quasi-cylindrical areas such as the shoulders and arms of the non-woven surgical gown, or hot-melting will cause the channel on the surgical gown used for wearing and taking off to be closed by hot-melt; and, a workbench for carrying the non-woven surgical gown is arranged above the workbench, and a driving and pressing roller is arranged above the workbench, and a roller that can be adjusted up and down is also arranged inside, but in the process of hot-melting the non-woven fabric of the surgical gown, because the pressure roller itself has a certain temperature, and this temperature can hot-melt the non-woven fabric of the surgical gown, the hot-melting part of the non-woven surgical gown still has a relatively high temperature residue after hot-melting, which will cause a certain bonding phenomenon, and this bonding phenomenon is extremely likely to cause excessive hot-melting of the non-woven surgical gown. To this end, we provide a non-woven surgical gown hot melt joining device to solve the above problems. Utility Model Content
