Abstract
Description
Technical Field
[0001] The utility model relates to cloth processing equipment, in particular to a double-head elastic film forming machine. Background Art
[0002] The fabric used for medical bandages usually has a certain elasticity for the purpose of facilitating bandaging. It is generally made of non-woven fabric and elastic film. Current medical fabrics are composed of double-sided non-woven fabrics with an elastic film in the middle. When processing medical fabrics, traditional equipment first bonds one side of the non-woven fabric to the elastic film, and then bonds the other side of the non-woven fabric. This is a side-by-side bonding method. Since medical fabrics need to be adjusted to have appropriate elasticity, the traditional side-by-side bonding method will cause inconsistent elasticity on each side, resulting in certain problems in the molding of the fabric. In addition, the side-by-side bonding method is inefficient. Therefore, it is extremely necessary to design a double-head elastic film shaping machine. Summary of the invention

[0016] Combination Figure 1-4 A double-head elastic film shaping machine includes a left non-woven fabric unwinding machine 1 and a right non-woven fabric unwinding machine 2 respectively arranged at the left and right ends. Specifically, the left non-woven fabric unwinding machine 1 unwinds non-woven fabric a, and the right non-woven fabric unwinding machine 2 unwinds non-woven fabric b.
[0017] A gantry 3 is provided between the left non-woven fabric unwinding machine 1 and the right non-woven fabric unwinding machine 2, and the gantry 3 is provided with a composite workbench 4, an elastic film unwinding machine 5, a stretching roller 6 and a PE film winding roller 7. A forming cloth winding machine 8 is also provided at the side end of the left non-woven fabric unwinding machine 1; specifically, the elastic film unwinding machine 5 unwinds the c elastic film, and simultaneously unwinds the a and b fabrics and the c elastic film at the left and right ends, and then gathers and bonds them in the composite workbench 4 of the gantry to form a formed cloth.
[0018] The stretching roller 6 and the PE film winding roller 7 are arranged at the upper end of the gantry 3. The gantry 3 is also provided with a PE guide roller 9 and a PU guide roller 10. The PE guide roller 9 is arranged close to the PE film winding roller 7, and the PU guide roller 10 is arranged close to the composite workbench 4. Specifically, the elastic film unwound by the elastic film unwinding machine 5 is a two-layer film, one layer is a PE elastic film, and the other layer is a PU elastic film. The PU elastic film plays a role in assisting the unwinding of the PE elastic film. The PE elastic film is a film bonded to the a and b non-woven fabrics. Therefore, before the PE elastic film is collected and bonded, it is necessary to peel the PU elastic film off the PE elastic film first. Therefore, a PE guide roller 9 and a PU guide roller 10 are arranged above the composite workbench 4 to respectively guide the separation of the PE film and the PU film, wherein the PU film is rolled up and recovered by the PE film winding roller 7 after separation, and the PE film is bonded to the a and b fabrics after separation; the function of the stretching roller is to adjust the elasticity of the elastic film.
[0019] The composite workbench 1 is arranged at the left end of the gantry 1, and the composite workbench 1 includes a left composite mechanism 11 and a right composite mechanism 12 which are symmetrically arranged. The left composite mechanism 11 includes a left rubber disc 13, a left anilox roller 14, a left embossing roller 15 and a left pressing roller 16. The left rubber disc 13 is in close contact with one side of the left anilox roller 14, and the left embossing roller 15 is in close contact with the other side of the left anilox roller 14.
[0020] The right composite mechanism 12 includes a right rubber disc 17, a right anilox roller 18, a right embossing roller 19 and a right pressing roller 20. The left pressing roller 16 and the right pressing roller 20 are arranged to press each other.
[0021] The present invention comprises a plurality of bending rollers, and specifically, the bending rollers play the role of guiding and tightening.
[0022] Specifically, in order to achieve lamination, the elastic film and the non-woven fabrics on the left and right sides of the elastic film need to be bonded, so the left laminating mechanism 11 and the right laminating mechanism 12 are symmetrically arranged, so the left pressing roller 16 and the right pressing roller 20 are mutually pressed;
[0023] The design of the gantry 3 of the present invention allows personnel to walk under the gantry to conveniently observe the operation of the entire equipment.
[0024] Working principle: the left non-woven fabric unwinder unwinds fabric a, the right non-woven fabric unwinder unwinds fabric b, and the elastic film unwinder unwinds double-layer elastic film c. Fabric a goes directly to the left side of the composite workbench. Specifically, fabric a goes to the left embossing roller, and then is embossed by the left anilox roller, and then goes to the left pressing roller and goes between the left pressing roller and the right pressing roller. Similarly, fabric b goes directly to the right side of the composite workbench and goes between the left pressing roller and the right pressing roller. After the elastic force of the c elastic film is adjusted by the stretching roller above the gantry, the PE film and the PU film are separated, and the PU film goes to the PU film winder for winding, and the PE film goes to the composite workbench. Specifically, the PE film passes between the left pressing roller and the right pressing roller and is pressed and formed with fabrics ab.
[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
