[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figures 1 to 3 As shown, the embodiment of the present invention provides a heat ironing device for producing film document bags, comprising an upper support plate 1, a lower support plate 2, a height adjustment assembly 3, a clamping wheel traction mechanism 4, a heating and punching mechanism 5, an edge banding wheel assembly 6, and an embossing wheel assembly 7;

[0033] The upper support plate 1 is located above the lower support plate 2, and the upper support plate 1 and the lower support plate 2 are connected by an elastic guide rail assembly 8. The height adjustment assembly 3 is connected to the lower support plate 2. The height of the lower support plate 2 can be adjusted through the height adjustment assembly 3 so that the ironing device can be installed and used to adapt to bag making machines of different heights; the setting of the elastic guide rail assembly 8 can enable the upper support plate 1 and the lower support plate 2 to have an elastic adjustment effect, so as to perform adaptive adjustment according to film document bags of different thicknesses.

[0034] The clamping wheel traction mechanism 4 includes a driving motor 41, an active clamping wheel 42 and a driven clamping wheel 43. The active clamping wheel 42 is arranged on the lower support plate 2, and the driven clamping wheel 43 is arranged on the upper support plate 1. A first gap for a film document bag to pass through is formed between the active clamping wheel 42 and the driven clamping wheel 43. The driving motor 41 is connected to the active clamping wheel 42 to drive the active clamping wheel 42 to rotate. The active clamping wheel 42 and the driven clamping wheel 43 are engaged with each other. As the active clamping wheel 42 rotates, the driven clamping wheel 43 can be driven to rotate synchronously through the meshing connection. The film document bag is pulled due to the friction between the active clamping wheel 42 and the driven clamping wheel 43 and is smoothly transmitted forward along the first gap.

[0035] The heating punching mechanism 5, edge sealing wheel group 6 and embossing wheel group 7 are arranged in sequence between the upper support plate 1 and the lower support plate 2 along the conveying direction of the film document bag. Such an arrangement enables the film document bag to complete multiple processes such as punching, edge sealing and embossing on the same production line, so that the entire production process is integrated and continuously operated, greatly improving the production efficiency of the film document bag.

[0036] like Figure 1 and Figure 3 As shown, the heating punching mechanism 5 includes an upper press seat 51, a lower press seat 52, a heating seat 53, a punching cutter 54 and a lifting cylinder 55. The upper press seat 51 is arranged on the upper support plate 1, and the lower press seat 52 is arranged on the lower support plate 2. A second gap is formed between the upper press seat 51 and the lower press seat 52. The lifting cylinder 55 is arranged at the bottom of the lower press seat 52. The movable end of the lifting cylinder 55 is arranged upward and is connected to the heating seat 53 through a connecting frame. The punching cutter 54 is arranged on the side wall of the heating seat 53. The punching cutter 54 is used to cut holes in the film document bag in the second gap as the lifting cylinder 55 moves. A punching cutter 54 is installed on the side wall of the heating base 53, and the punching cutter 54 is connected to the heating base 53 so that the punching cutter 54 is in a high-temperature state. When the film document bag is transported to the second gap under the action of the clamping wheel traction mechanism 4, the lifting cylinder 55 can push the punching cutter 54 to move upward to cut the film document bag to form a hole. Due to the high temperature of the punching cutter 54, the film document bag can be quickly melted during cutting to achieve steam cutting, avoiding edge burrs, tearing and other problems.

[0037] like Figure 3 As shown, further, the upper press seat 51 and the lower press seat 52 are provided with a cutting groove 500 for the punching cutter 54 to move up and down. Such a setting can avoid collision and obstruction of the punching cutter 54 during the lifting and lowering movement, and improve the punching processing accuracy of the punching cutter 54.

[0038] like Figure 3As shown, the heating base 53 further has a receiving hole 530 therein, and a first heating tube 531 is disposed therein. The first heating tube 531 is used to heat the punching cutter 54. Placing the first heating tube 531 in the receiving hole 530 in the heating base 53 allows the heating tube to be in close contact with the heating base 53, thereby allowing heat to be quickly transferred from the heating tube to the punching cutter 54 to achieve heating.

[0039] like Figure 1 As shown, further, the edge banding wheel group 6 includes an upper pressing wheel 61 and a lower pressing wheel 62. The upper pressing wheel 61 is arranged on the upper support plate 1, and the lower pressing wheel 62 is arranged on the lower support plate 2. A third gap is formed between the upper pressing wheel 61 and the lower pressing wheel 62 for the film document bag to pass through. During the transportation of the film document bag, the upper pressing wheel 61 and the lower pressing wheel 62 will apply uniform pressure to the edge portion of the film document bag to tightly fit the upper and lower layers of the film document bag together. It should be noted that during the transportation of the film document bag, the heating seat 53 will heat the upper and lower layers of the film document bag to soften the film document bag.

[0040] like Figure 1 As shown, further, the embossing wheel group 7 includes an upper embossing wheel 71, a lower pulley 72 and a second heating tube 73. The upper embossing wheel 71 is arranged on the upper support plate 1 through a first connecting rod 74, and the lower pulley 72 is arranged on the lower support plate 2 through a second connecting rod 75. The surface of the upper embossing wheel 71 is provided with a pattern texture structure 710, and the pattern texture structure 710 is used to be printed on the surface of the film document bag as the upper embossing wheel 71 is squeezed. The second heating tube 73 is connected between the first connecting rod 74 and the second connecting rod 75. The second heating tube 73 is used to heat the upper embossing wheel 71 and the lower pulley 72. Before starting the embossing process, the second heating tube 73 is powered on and heated, and the heat is transferred to the upper embossing wheel 71 and the lower pulley 72 through the first connecting rod 74 and the second connecting rod 75, ensuring that the upper embossing wheel 71 and the lower pulley 72 reach a suitable working temperature, thereby softening the film document bag but not melting or damaging it. Under the action of pressure, the upper embossing wheel 71 clamps the film document bag together with the lower pulley 72, thereby imprinting the pattern texture structure 710 on the surface of the upper embossing wheel 71 on the surface of the film document bag.

[0041] like Figure 2As shown, the elastic guide rail assembly 8 further includes a slide bar 81, a first slider 82, a second slider 83, and a tension spring 84. The two slide bars 81 are respectively located on either side of the back of the upper support plate 1 and the lower support plate 2. The back of the upper support plate 1 is connected to the top of the slide bar 81 via the first slider 82, and the lower support plate 2 is connected to the bottom of the slide bar 81 via the second slider 83. The first slider 82 and the second slider 83 are connected by the tension spring 84, which is used to move the upper support plate 1 and the lower support plate 2 closer to each other. When a thicker film document bag passes through, the film document bag pushes the upper support plate 1 and the lower support plate 2 slightly apart, further stretching the tension spring 84. This arrangement allows the gap between the upper support plate 1 and the lower support plate 2 to automatically adjust according to the thickness of the material, thereby applying appropriate pressure to the film document bag.

[0042] like Figure 2 As shown, further, the height adjustment assembly 3 includes a rotating handwheel 31, a screw shaft 32 and a threaded seat 33, the threaded seat 33 is arranged on the back of the lower support plate 2, the screw shaft 32 is arranged between the two sliding rods 81, and the screw shaft 32 is sleeved and connected with the threaded seat 33, the rotating handwheel 31 is arranged at the top of the screw shaft 32, the rotating handwheel 31 is used to drive the screw shaft 32 to rotate, and the threaded seat 33 is used to drive the lower support plate 2 to move up and down as the screw shaft 32 rotates, thereby driving the lower support plate 2 to achieve height adjustment.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
