[0051] The mounting frame 500 is connected to the adjusting assembly 200 and is used for mounting the adjusting assembly 200.

[0052] It should be noted that the spacing between the outer sides (the sides far away from each other) of the two forming templates 120 is smaller than the width of the film material 400, after the film material 400 enters between the two forming templates 120 and the forming panel 130, the flanging assembly 300 presses the part of the film material 400 exceeding the outer sides of the two forming templates 120 to the upper surface of the two forming templates 120 to form the folded film 410, and the part of the film material 400 between the two forming templates 120 and the forming panel 130 forms the bottom film 420;

[0053] After the film material 400 is flanged, a bottom film 420 and two folded films 410 are formed, the top surface of the bottom film 420 is attached to the bottom surface of the two forming templates 120, the bottom surface of the bottom film 420 is attached to the top surface of the forming panel 130, the bottom surface of the folded film 410 is attached to the top surface of the two forming templates 120, the sum of the widths of the two folded films 410 is greater than the width of the bottom film 420, and the two folded films 410 partially overlap, and the overlapping part forms a heat-sealed edge after heat-sealing treatment.

The second guide roller 328 is in rotary connection with the second rotating rod 327 through a bearing. The first guide roller 318 and the second guide roller 328 are both conical rollers. The first guide roller 318 and the second guide roller 328 are used for flanging the film material 400. The size of the first guide roller 318 is smaller than that of the second guide roller 328. When the folded film 410 passes through the first guide roller 318, part of the folded film 410 is attached to the forming die plate 120. When the folded film 410 passes through the second guide roller 328, the folded film 410 is completely attached to the forming panel 130 (part of the area of one folded film 410 is attached to another folded film 410). The film material 400 is gradually flanged through the first flanging part and the second flanging part, and the flanging effect is better.

[0080] In the first flanging unit 310, the first fastening handle 312 is loosened. The first connecting seat 311 can slide along the length direction of the position adjusting groove 131, so as to adjust the position of the first flanging unit 310, and further adjust the flanging position of the film material 400, so that the flanging effect of the film material 400 is better. The first rotating rod 317 is in rotary connection with the first supporting rod 315. The fourth fastening handle 3110 is loosened. The first weight block 319 can move along the length direction of the first rotating rod 317, so as to adjust the pressing degree of the first guide roller 318 and the folded film 410. It can be ensured that the first guide roller 318 can press the folded film 410 on the forming die plate 120, and the friction force between the folded film 410 and the forming die plate 120 is appropriate, and the film material 400 can be normally fed.

[0081] Loosen the second fastening handle 314, the second connecting block 323 can rotate around the center line of the first connecting seat 311, driving the first supporting rod 315, the first rotating rod 317, the first guide roller 318 and the first weight block 319 to rotate synchronously, loosen the third fastening handle 316, the first supporting rod 315 can rotate around its center line, or slide along its length direction, driving the first rotating rod 317, the first guide roller 318 and the first weight block 319 to move synchronously, so that the first guide roller 318 better cooperates with the forming template 120, and the folding film 410 better adheres to the forming template 120;

[0082] The adjustment principle of the second flanging unit 320 is similar to that of the first flanging unit 310, which will not be repeated here.

[0083] In the embodiment, the first rotating rod 317 is rotatably connected with the first supporting rod 315 through an internal hexagonal cylindrical head screw, and the second rotating rod 327 is rotatably connected with the second supporting rod 325 through an internal hexagonal cylindrical head screw. When the internal hexagonal cylindrical head screw is tightened, it can also play a locking role. Two groups of second flanging parts are arranged along the feeding direction of the film material 400. By arranging two groups of second flanging parts, the film material 400 can be better wrapped on the forming template 120, and the folding film 410 better adheres to the forming template 120.

[0084] Example 8:

[0085] As an optimization of example 7, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 12 , the flanging assembly 300 further comprises a mounting part 330, a ninth fastening handle 340 and a folding plate 350. The ninth fastening handle 340 is in sliding fit with the positioning slot 131. The mounting part 330 is locked on the forming panel 130 through the ninth fastening handle 340. The folding plate 350 is installed on the mounting part 330.

[0086] It should be noted that when the folding film 410 passes between the folding plate 350 and the forming template 120, the folding plate 350 and the forming template 120 cooperate to extrude the film material 400, so that the crease area of the flanged part of the film material 400 has a certain hardening effect, the crease line 430 is more stable, and the flanging effect of the film material 400 is better. Loosen the ninth fastening handle 340, the ninth fastening handle 340 can move along the length direction of the positioning slot 131, thereby driving the mounting part 330 and the folding plate 350 to move, and adjusting the position of the folding plate 350.

[0087] Example 9:

[0088] As an optimization of example 8, as shown in Figure 1 、 Figure 2, Figure 3 , Figure 4 , Figure 12 and Figure 13 As shown, the mounting part 330 includes a bolt seat 331, a first adjusting nut 332, and a second adjusting nut 333. The bolt seat 331 is threadedly connected to the ninth locking handle 340. The folded edge plate 350 is provided with an adjusting groove 351. The folded edge plate 350 is movably engaged with the bolt seat 331 through the adjusting groove 351. The first adjusting nut 332 and the second adjusting nut 333 are both threadedly connected to the bolt seat 331. The top surface of the first adjusting nut 332 abuts against the bottom surface of the folded edge plate 350, and the bottom surface of the second adjusting nut 333 abuts against the top surface of the folded edge plate 350.

[0089] It should be noted that the first adjusting nut 332 and the second adjusting nut 333 clamp and fix the folding plate 350. By adjusting the position of the first nut and the second nut, the height of the folding plate 350 can be adjusted. When the first nut and the second nut are not clamping the folding plate 350, the folding plate 350 can rotate and slide, thereby adjusting the position of the folding plate 350 so that the folding plate 350 can better cooperate with the forming template 120 to compress film materials 400 of different thicknesses and form stable crease lines 430.

[0090] Example 10:

[0091] As an optimization of Example 9, such as Figure 13 As shown, the folding plate 350 includes an adjustment section 352, an inclined section 353 and an extrusion section 354 connected sequentially along the direction close to the forming template 120. The adjustment groove 351 is located in the adjustment section 352, and the inclined section 353 is inclined downward along the direction close to the forming template 120.

[0092] It should be noted that the adjustment groove 351 is set on the adjustment section 352, and the extrusion section 354 abuts against the folded film 410. By setting the inclined section 353, the extrusion section 354 can extrude the folded film 410 in a surface contact manner, which is conducive to forming stable crease lines 430.
