[0002] In the field of modern raincoat production and manufacturing, automatic folding and cutting machines have become key equipment for improving the efficiency and quality of raincoat production due to their high efficiency and stability. The automatic folding and cutting machines can fold and cut the raincoat raw materials quickly and accurately through automated operation, effectively reducing labor costs and improving production efficiency. However, the common automatic folding and cutting machines on the market currently have obvious technical defects. They can only perform folding and heat-sealing treatment on both sides of the raincoat raw materials, such as an automatic folding and buttoning raincoat cutting machine disclosed in application number CN202223609118.3. After the raincoat raw materials are cut into independent blocks, the edges at both ends of the cut are in an unprocessed state and need to be folded and heat-sealed with the help of other equipment. How to achieve folding and heat-sealing of the two ends of the cut raincoat raw materials to complete the comprehensive folding and heat-sealing treatment of the four sides of the cut raincoat raw materials, thereby improving the quality and efficiency of raincoat production, has become a technical problem that needs to be solved urgently in this field.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides a folding and heat-sealing device for the end portion of a raincoat raw material of an automatic folding and cutting machine.

[0026] In this embodiment, referring to Figure 1-5 The folding and heat-sealing device for the end of the raincoat raw material of the automatic folding and cutting machine includes a frame 1, and the frame 1 is provided with a guide roller group 2, a first folding and heat-sealing component 3, a cutting component 4 and a second folding and heat-sealing component 5 in sequence from the feed end to the discharge end.

[0027] In the above scheme, a material guide roller assembly, a first hem-folding and heat-sealing assembly, a cutting assembly, and a second hem-folding and heat-sealing assembly are sequentially arranged on the frame from the feed end to the discharge end. The material guide roller assembly guides the raincoat raw material along a set path, facilitating docking with the existing automatic hem-folding and heat-sealing machine. The raw material first passes through the first hem-folding and heat-sealing assembly for hem-folding and heat-sealing at one end, and then the cutting assembly cuts the raw material. The cut raw material then passes through the second hem-folding and heat-sealing assembly for hem-folding and heat-sealing at the other end. This solves the problem that existing automatic hem-folding and heat-sealing machines are unable to hem-fold and heat-seal both ends of cut raincoat raw material. It achieves simultaneous hem-folding and heat-sealing of both ends of each cut piece of raincoat raw material. Combined with hem-folding and heat-sealing on both sides, it can simultaneously hem-fold and heat-seal all four sides of the cut raincoat raw material, improving production efficiency and reducing production processes and time costs.

[0028] Specifically, the cutting assembly includes a heating wire 6 and a first lifting drive assembly that drives the heating wire up and down to complete the cutting of the raincoat material.

[0029] In this embodiment, the cutting assembly uses a first lift drive assembly to move the heating wire up and down. When the heating wire descends to contact the raincoat material, the high temperature generated by the heating wire melts the material, completing the cutting process. By controlling the lift stroke and speed of the first lift drive assembly, the cutting position and cutting effect can be precisely controlled.

[0030] The electric heating wire cutting method is used. Compared with traditional mechanical knife cutting, the incision is smoother and less prone to burrs. The cutting process is fast, reducing the damage to the raincoat material caused by cutting. The first lifting drive component realizes automatic control of the cutting action, improves the accuracy and stability of cutting, and ensures the quality and efficiency of subsequent folding and heat sealing.

[0031] Specifically, the first folding heat sealing assembly and the second folding heat sealing assembly each include a heat sealing mechanism and a folding mechanism;

[0032] The heat sealing mechanism includes a fixed plate 7 fixed on the frame, a movable plate 8 and a driving mechanism for driving the movable plate to clamp the fixed plate, and a heating plate is fixed on the fixed plate or the movable plate;

[0033] The folding mechanism includes a folding beam 9, a folding insert 10 fixed to the folding beam 9, a slide rod 12 slidably connected to a slide hole 11 of the folding beam, a pressing plate 13 fixed to the slide rod, and a second lifting drive assembly for driving the folding beam up and down;

[0034] A hemming groove 14 for inserting a hemming inserting plate is formed between the fixed plate and the movable plate.

[0035] In this embodiment, the heat sealing mechanism and the folding mechanism cooperate with each other to realize the integrated operation of folding and heat sealing of the raincoat raw materials, thereby improving the efficiency and quality of folding and heat sealing; the design of the folding insert plate and the folding groove can accurately fold the edges of the raw materials to ensure the neatness of the folding; the heating of the heating plate and the clamping action of the moving plate make the folding firmly heat-sealed, effectively avoiding problems such as delamination and cracking, and improving the waterproof performance and durability of the raincoat.

[0036] Specific principles:

[0037] Heat sealing mechanism: The driving mechanism drives the movable plate to clamp the fixed plate. When the folded raincoat material is placed between the fixed plate and the movable plate, the heating plate fixed on the fixed plate or the movable plate heats the material. At the same time, the movable plate clamps the material, so that the folded edge of the material is heated and fused to complete the heat sealing operation.

[0038] Folding mechanism: The second lifting drive assembly drives the folding beam up and down. The folding insert on the folding beam is inserted into the folding groove between the fixed plate and the movable plate to fold the edge of the raincoat material. The slide rod and the pressure plate play the role of auxiliary positioning and fixing the material to ensure the accuracy and stability of the folding.

[0039] Specifically, the guide roller group includes a mounting plate 15 fixed on both sides of the frame, a rotating shaft roller 16 rotatably connected to the mounting plate 15, a bearing plate 17 slidably connected in the slide groove of the mounting plate, an adjusting roller 18 rotatably connected to the bearing plate, and an adjusting cylinder 19 for driving the adjusting roller to move closer to or away from the rotating shaft roller.

[0040] In this embodiment, the guide roller assembly features a rotating shaft roller fixed to a mounting plate, while an adjustment roller is slidably connected to a slot in the mounting plate via a bearing plate. An adjustment cylinder drives the bearing plate to slide within the slot, thereby moving the adjustment roller toward or away from the rotating shaft roller. Adjusting the spacing between the adjustment roller and the rotating shaft roller allows for guidance and tension adjustment of raincoat materials of varying thicknesses, ensuring smooth material transport. The adjustable design of the guide roller assembly accommodates raincoat materials of varying specifications, enhancing the versatility of the device.

[0041] Specifically, the driving mechanism includes a dual-axis motor 20, a driving shaft 21 connected to the dual-axis motor 20, a cam 22 fixed to the driving shaft, and a driving crank arm connected to the cam 22 for respectively driving the movable plate of the first folding heat sealing assembly and the second folding heat sealing assembly to perform a clamping action toward the fixed plate;

[0042] The driving crank arm includes a connecting rod 23 having one end rotationally connected to the cam, a transfer shaft 25 rotationally connected to the frame through a bearing seat 24, a first transfer arm 26 fixed on the transfer shaft 25, and a driving rod 27 connected to the first transfer arm 26. One end of the connecting rod is connected to the transfer shaft through a second transfer arm 28, and the driving rod is connected to the moving plate.

[0043] In this embodiment, the dual-axis motor drives the drive shaft to rotate, and the cam on the drive shaft rotates accordingly. The rotation of the cam drives the second transfer arm through the connecting rod, causing the transfer shaft to rotate, and then drives the first transfer arm to rotate. The first transfer arm drives the movable plate to clamp toward the fixed plate through the drive rod.

[0044] The driving mechanism consists of a cam and a driving arm, which has a compact structure and stable transmission. It can provide a stable and controllable clamping force for the heat sealing mechanism, ensuring the consistency and reliability of the heat sealing effect. The first folding heat sealing component and the second folding heat sealing component are driven simultaneously by a dual-axis motor to achieve synchronous movement of the two components, improve the working efficiency of the overall device, and reduce the complexity and cost of the power system.

[0045] Specifically, the first lifting drive assembly and the second lifting drive assembly both include a lifting rail 30 connected to the frame through a slider 29, a rack 31 fixed on the lifting rail, a driving gear 32 driven by the rack, and a rotation drive mechanism 33 that drives the driving gear to rotate.

[0046] In this embodiment, a rotary drive mechanism in the first and second lift drive assemblies rotates a driving gear, which meshes with a rack fixed to the lift rail, converting the rotary motion into linear motion. This drives the lift rail up and down on the frame via a slider. In the cutting assembly, this structure raises and lowers the heating wire to achieve the cutting action; in the hemming mechanism, it drives the hemming beam up and down to complete the hemming operation. By controlling the rotational direction, speed, and angle of the driving gear, the travel and position of the lift rail can be precisely controlled.

[0047] The rotary drive mechanism can use a combination of a motor and a pulley to realize the rotary drive of the driving gear or directly realize it through a combination of a motor, a reducer and a gear. The above rotary drive mechanism belongs to the conventional setting of mechanical transmission and will not be described in detail here.

[0048] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
