Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a raincoat heat-sealing machine module. Background Art

[0002] As a kind of rain-proof clothing made of waterproof fabric by a heat-sealing machine, the raincoat is not restricted by seasons and regions, and has a large market demand. The raincoat includes a body, a hat and sleeves. The production process generally consists of cutting - hemming - hat edge sealing - sleeve edge sealing - welding the body neckline - welding the body and cuffs - welding the body neckline and the hat - buttoning. Most of the processes are completed by the heat-sealing machine. That is, the heat-sealing machine performs a closing and heating treatment on the product. For example, in the existing heat-sealing machine for welding the hat and the body neckline, there are a lower heating plate and an upper pressing plate. During operation, it is necessary for workers to fold and weld the body hem and then thermally press and bond it with the hat manually.

[0003] Furthermore, when processing the raincoat, it is necessary to thermally press and connect the body with the sleeves, and the body neckline with the hat. The connecting lines between the body and the hat, and between the body neckline and the sleeves are all arc-shaped, which are difficult to position during the processing, and this is a technical problem to be solved. That is, due to the arc-shaped connecting line between the body neckline and the hat, it is very difficult to align the connecting part. Moreover, when folding the edges at both ends of the body neckline, it is necessary for workers to hold them with both hands and place them in the working area and tighten (also by tightening the aforementioned arc-shaped connecting line with both hands to facilitate processing and positioning). When the upper pressing plate drives down and is about to approach the lower die (lower heating plate), both hands can quickly withdraw. If the hands withdraw too early, the workpiece will shrink; if they withdraw too late, it will press the hands. This not only has low efficiency but also poses a greater safety hazard. Summary of the Invention

[0004] The purpose of the utility model is to provide a raincoat heat-sealing machine module to solve the problems in the background art, tighten and straighten the part of the raincoat to be processed for positioning (for pressing and / or cutting), liberate both hands, improve work efficiency and be safer.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a raincoat heat-sealing machine module, including a lower die and an upper die. A lower heating plate is arranged on the upper surface of the lower die along its length direction. Clamping mechanisms are symmetrically arranged on the left and right sides inside the lower die. The connecting line of the clamping openings of the symmetric clamping mechanisms is parallel to the lower heating plate. The symmetric clamping mechanisms can translate away from each other along the length direction of the lower die, and the symmetric clamping mechanisms can translate along the width direction of the lower die.

[0006] Furthermore, the clamping mechanism includes two groups of clamping pliers symmetrically arranged horizontally on the left and right. When the clamping openings of the clamping pliers are closed tightly, the clamping openings of the clamping pliers are flush with the plate surface of the lower heating plate.

[0007] Furthermore, at least one side of the clamping opening of the clamping pliers faces the lower heating plate. Each group of clamping pliers is connected to a first driving cylinder, and the first driving cylinder drives the clamping pliers to translate along the length direction of the lower die.

[0008] Furthermore, an included angle is formed between the clamping jaws of the clamp and the lower heating plate, and the clamping jaws of the two groups of clamps are arranged facing each other at an acute angle.

[0009] Furthermore, the clamp is arranged parallel to the lower heating plate, a second driving cylinder is vertically arranged on the lower die, and the second driving cylinder drives the first driving cylinder and the clamp to translate along the width direction of the lower die.

[0010] Furthermore, the first driving cylinder is arranged parallel to the lower heating plate, the second driving cylinder is arranged perpendicular to the first driving cylinder, and the second driving cylinder drives the assembly composed of the first driving cylinder and the clamp to move synchronously, or the first driving cylinder drives the assembly composed of the second driving cylinder and the clamp to move synchronously.

[0011] Furthermore, heating wires and cutting wires are fixedly arranged on the lower heating plate along the length direction of the plate.

[0012] Furthermore, an upper pressing plate is arranged below the upper die, and the upper pressing plate is a telescopic silica gel part.

[0013] Furthermore, a cooling water channel is arranged inside the lower die along the length direction thereof.

[0014] The technical effect of the present utility model lies in that: the two groups of symmetric clamping mechanisms translate away from or towards each other along the length direction of the lower die, and this translation amount is determined to be consistent according to the stretchable and straightenable amount of the workpiece to be processed; the symmetric clamping mechanisms translate close to or away from the lower die along the width direction of the lower die, and this translation amount facilitates the removal of the cut waste. That is, when the workpiece to be processed comes in, the clamping mechanisms perform translation away from each other to realize stretching and straightening for positioning, and then perform pressing and cutting. The clamping mechanisms clamp the cut waste and then translate inward along the width direction of the lower die, that is, translate away from the lower die direction. The clamping jaws of the clamping mechanisms loosen, and the cut waste falls freely, and then the next cycle of operation is performed. In this way, the part of the raincoat to be processed is stretched and straightened for positioning, pressing and cutting, which liberates the hands, improves the work efficiency and is safer.

[0023] Referring to the attached drawings, a raincoat heat-sealing machine module includes a lower mold and an upper mold. Along the length direction of the upper surface of the lower mold, a lower heating plate 20 is provided. On the inner side of the lower mold, clamping mechanisms 30 are symmetrically arranged on the left and right. The connecting line of the clamping openings of the symmetric clamping mechanisms 30 is parallel to the lower heating plate 20. The symmetric clamping mechanisms 30 can be translated away from each other along the length direction of the lower mold, and the symmetric clamping mechanisms 30 can be translated along the width direction of the lower mold.

[0024] That is, the two symmetric clamping mechanisms 30 are translated away from or towards each other along the length direction of the lower mold, and this translation amount is determined to be consistent according to the amount that the workpiece A to be processed can be tightened and straightened; the symmetric clamping mechanisms 30 are translated closer to or away from the lower mold along the width direction of the lower mold, and this translation amount facilitates the removal of the cut waste. That is, when the workpiece A to be processed arrives, the clamping mechanisms 30 perform a translation away from each other to achieve tightening and straightening for positioning, and then perform pressing and cutting. The clamping mechanisms 30 clamp the cut waste and then translate inwards along the width direction of the lower mold, that is, translate away from the lower mold direction. The clamping openings of the clamping mechanisms 30 loosen, and the cut waste freely falls, and then the next cycle of actions is performed. [This action can be performed in one step or two steps, refer to the following description]

[0025] Further, the clamping mechanism 30 includes two groups of pliers 31 that are symmetrically arranged horizontally. When the clamping openings of the pliers 31 are closed, the clamping openings of the pliers 31 are flush with the plate surface of the lower heating plate 20.

[0026] A specific implementation manner is given: the lower clamping jaws of the pliers 31 are in the same plane as the lower heating plate 20. When the pliers 31 perform a clamping action, the upper clamping jaws clamp downwards. In this way, when the clamping openings of the pliers 31 are closed, the clamping openings of the pliers 31 are arranged flush in the same plane as the lower heating plate 20.

[0027] Further, at least one side of the clamping mouth of the clamp 31 is arranged towards the lower heating plate 20. Each group of clamps 31 is connected to the first driving cylinder 32, and the first driving cylinder 32 drives the clamp 31 to translate along the length direction of the lower die.

[0028] That is, each group of clamps 31 is arranged horizontally (which can be horizontally offset) along the transverse direction of the raincoat heat-sealing machine module. The first driving cylinder 32 drives the clamp 31 to move back and forth horizontally along the transverse direction of the raincoat heat-sealing machine module.

[0029] Furthermore, referring to Figure 3 , in the first embodiment of the present invention: there is an included angle between the clamping mouth of the clamp 31 and the lower heating plate 20, and the clamping mouths of the two groups of clamps 31 are arranged facing each other at an acute angle. That is, according to the set translation amount, one step action of the first driving cylinder 32 is executed to realize the translation of the clamps 31 away from or towards each other along the length direction of the lower die and the approach to or separation from the lower die along the width direction of the lower die.

[0030] Furthermore, the clamp 31 and the lower heating plate 20 are arranged in parallel [refer to the attached Figure 4 and Figure 6 , the parallel arrangement of the clamp 31 means that the clamping mouth of the clamp 31 can be arranged longitudinally or horizontally]. There is a second driving cylinder 33 vertically arranged on the lower die. The second driving cylinder 33 drives the first driving cylinder 32 and the clamp 31 to translate along the width direction of the lower die.

[0031] That is, the first driving cylinder 32 drives the clamp 31 to translate along the length direction of the lower die of the lower mold. The second driving cylinder 33 drives the clamp 31 to translate closer to or away from the lower die in the width direction of the mold.

[0032] Furthermore, referring to the attached Figure 6 , in the third embodiment of the present invention: the first driving cylinder 32 and the lower heating plate 20 are arranged in parallel, the second driving cylinder 33 is arranged perpendicular to the first driving cylinder 32, and the second driving cylinder 33 drives the assembly composed of the first driving cylinder 32 and the clamp 31 to move synchronously. Or referring to the attached Figure 4 , in the second embodiment of the present invention: the first driving cylinder 32 drives the assembly composed of the second driving cylinder 33 and the clamp 31 to move synchronously.

[0033] That is, the second driving cylinder 33 drives the clamp 31 to move along the plate width direction of the lower heating plate 20, and the first driving cylinder 32 drives the second driving cylinder 33 and the clamp 31 to move along the plate length direction of the lower heating plate 20. Similarly, in another set of solutions: the first driving cylinder 32 drives the clamp 31 to be arranged along the plate length direction of the lower heating plate 20, and the second driving cylinder 33 drives the first driving cylinder 32 and the clamp 31 to approach or move away from the lower die vertically. [Refer to Figure 4, that is, the second driving cylinder 33 and the clamp 31 form a component, and the first driving cylinder 32 drives this component; referring to Figure 6 , it can also be that the first driving cylinder 32 and the clamp 31 form a component, and the second driving cylinder 33 drives this component. The said component is a clamp seat, and the clamp seat is set to be adjustable to facilitate meeting the adjustment of different workstations.

[0034] Furthermore, one set or multiple sets of material clamping mechanisms are arranged between the symmetric clamping mechanisms 30. The said material clamping mechanisms are arranged in parallel with the clamping mechanisms 30, that is, the material clamping mechanisms are also arranged inside the lower die. The clamping jaws of the material clamping mechanisms open and close synchronously with the clamps 31 of the clamping mechanisms 30. A pushing cylinder is arranged on the material clamping mechanism. The said pushing cylinder pushes the material clamping mechanism to translate along the width direction of the lower die, and its translation amount is consistent and synchronous with that of the clamping mechanism 30, so as to further strengthen the grasping of the sheared waste. The clamping jaws of the material clamping mechanism and the clamps 31 of the clamping mechanism 30 open synchronously to make the waste fall freely.

[0035] Furthermore, heating wires 21 and cutting wires 22 are fixedly arranged along the plate length direction of the lower heating plate 20. The cross-section of the cutting wire 22 adopts round wire, so that the contact area of the cutting wire 22 is small and it is easy to cut. Since the cross-sectional shape is arc-shaped, the cut is smooth. The heating wire 21, that is, the welding wire, adopts flat wire in cross-section, so that the contact area of the welding wire is large and the welding is firm.

[0036] Furthermore, an upper pressing plate 10 is arranged under the upper die, and the upper pressing plate 10 is a telescopic silica gel part.

[0037] Furthermore, a cooling water channel 40 is arranged along the length direction inside the lower die. Since the heating wire 21 (welding wire) and the cutting wire 22 are in a high-temperature working state for a long time, water circulation cooling is adopted through the cooling water channel 40.

[0038] To sum up, the present utility model solves the technical problems that the processing efficiency of the welding equipment for heat-sealing the collar and hat of the raincoat body is low and there are potential safety hazards. The heating wire 21 (that is, the welding wire) and the cutting wire 22 are fixed on the upper plane of the lower die of the heat-sealing machine. The workpiece A is held, stretched and tightened by two symmetric strong clamps 31 on the outer side of the lower die (that is, the side close to the worker) and then moved forward. Then the upper die drives to make the workpiece A contact with the heating wire 21 to complete heat-sealing and cut off the redundant materials, which is convenient to operate. After the work is completed, the clamp 31 can automatically pull away the remaining materials, which is faster and safer.

[0039] The driving of the clamp 31 and the clamping jaws adopts any one of pneumatic, electric and hydraulic transmission methods, that is, the aforementioned cylinder is not limited to pneumatic, and can also be electric, hydraulic or other mechanical transmissions.

[0040] In addition, the clamp 31 and the clamping jaws can be equipped with friction sheaths to increase their clamping force.
