Description

Technical Field

[0001] This utility model relates to the field of raincoat folding processing technology, and more specifically to a four-sided folding and welding processing mechanism for the production of ponchos and raincoats. Background Technology

[0002] A poncho raincoat is a type of raincoat. During its processing, it uses a single rectangular piece of plastic fabric as the material. In the process of processing, the four sides of the rectangular plastic fabric need to be folded and welded to improve the wear resistance and smoothness of the raincoat's edges.

[0003] Currently, when processing the four sides of ponchos and raincoats by machine, only three sides can often be pre-processed. Then, a robotic arm pulls the fabric detached from the roll onto a folding and welding machine for folding and welding. With this processing method, since the semi-finished product with three sides already separated from the roll, and because EVA fabric is light, thin, and soft, and also generates a certain amount of static electricity, the fabric is in a free state after being separated from the roll. Coupled with air resistance, the consistency of the fabric's state in the folding and welding process deteriorates, and the quality of the final folding and welding process becomes uncontrollable, increasing the scrap rate and manual sorting costs.

[0004] In view of this, this utility model proposes a four-sided folding and welding edge processing mechanism for the production of ponchos and raincoats to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a four-sided folding and welding edge processing mechanism for the production of ponchos and raincoats, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a four-sided folding and welding edge processing mechanism for the production of ponchos and raincoats, including a frame, wherein the frame is provided from left to right with a feeding and correction mechanism, a folding mechanism, a hot welding edge mechanism, a hem speed buffer mechanism one, a buttoning mechanism, a hem speed buffer mechanism two, a hat position marking mechanism, a double hem folding mechanism, and two sets of robotic arm linkage gripping mechanisms for pulling the fabric;

[0007] The folding mechanism is used to fold the front and back sides of the fabric. The folding mechanism includes a base plate set on the surface of the frame, and a folding piece set on the top of the frame corresponding to the base plate. The front and back sides of the fabric are folded through the gap formed by the folding piece and the base plate, and the folding amount is adjusted by adjusting the position of the folding piece.

[0008] The hot welding edge mechanism includes a silicone roller and a heating welding plate set on the surface of the frame. The fabric is conveyed between the silicone roller and the heating welding plate, and the front and rear sides of the fabric are welded by heating the heating wire built into the heating welding plate.

[0009] The double hem folding mechanism includes two downward electric cylinders, or two pneumatic cylinders, symmetrically arranged above the frame. Each pair of downward electric cylinders forms a group. A welding block is fixedly installed at the telescopic end of each group of downward electric cylinders. The welding block has a built-in heating rod or a surface-mounted heating wire to heat the fabric. A welding fixing base is provided on the surface of the frame below the welding block, providing bottom support for the welding. A folding fixing block and a synchronous wheel mechanism are arranged above the frame. A folding movable block is arranged on the surface of the synchronous wheel mechanism. An electric cutting wire and a cutting cylinder that drives the electric cutting wire to move up and down are arranged above the frame. A fabric pressing base, a fabric pressing cylinder, and a fabric pressing rod fixedly installed at the telescopic end of the fabric pressing cylinder are arranged above the frame. The fabric pressing rod corresponds to the position of the fabric pressing base.

[0010] Furthermore, the inner wall of the frame is provided with several conveying rollers for supporting the fabric.

[0011] As a further description of the above technical solution: by setting up conveyor rollers, it is convenient to continuously convey the strip fabric.

[0012] Furthermore, the first and second hem speed buffer mechanisms are used to adjust the speed of the fabric at the button attaching machine, so that the machine can still operate normally despite the speed difference between the front and rear.

[0013] Furthermore, the fastening mechanism includes a fastening machine fixedly mounted above the frame.

[0014] As a further description of the above technical solution: by setting up a button-attaching machine, it is possible to perform button-attaching processing on both sides of the fabric.

[0015] Furthermore, the hat position marking mechanism includes a marking cylinder fixedly installed above the frame and a cold knife fixedly installed on the surface of the telescopic end of the marking cylinder. The marking cylinder and the cold knife punch holes in the hat position to facilitate accurate positioning during subsequent manual welding of the hat.

[0016] As a further description of the above technical solution: by setting a marking cylinder and a cold knife, holes can be punched at the cap position of the fabric, making it easier to accurately locate the cap during subsequent manual welding.

[0017] Furthermore, the synchronous pulley mechanism is a system composed of a motor, a synchronous pulley, and a synchronous belt. The rotation of the motor drives the synchronous pulley to rotate, causing the folded edge movable block to flip.

[0018] Furthermore, a connecting guide rail is provided above the frame, and the electric cutting wire is slidably connected to the inner wall of the connecting guide rail.

[0019] As a further description of the above technical solution: by setting a connecting guide rail, the lifting path of the electric cutting wire can be restricted, ensuring the stability of the electric cutting wire's movement.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. Compared with existing technologies, this four-sided folding and welding edge processing mechanism for producing raincoats involves conveying the plastic fabric used to make the raincoat from left to right on the machine frame surface. During the conveying process, the left and right sides of the fabric are folded and welded using a folding mechanism and a hot welding edge mechanism. Subsequently, through a double-swing folding mechanism, during the fabric conveying process, a cutting cylinder extends to drive the electric cutting wire downwards, enabling the fabric to be cut. Two folding movable blocks are flipped to fold the ends of the fabric. Then, from right to left, a downward electric cylinder drives the welding block downwards to weld the fabric. Following this action, the fabric on the left side of the cut wire is still on the roll. The feeding roller keeps it under tension, while the built-in vacuum pump on the folding and fixing rod keeps the fabric tightly attached to the folding rod for folding and welding while maintaining tension. The fabric on the right side of the cut wire is pressed by the pressing device and adsorbed onto the folding rod by the vacuum pump, allowing the fabric to be precisely folded and welded while maintaining tension. This achieves the purpose of precisely folding and welding the left and right sides of the cut fabric without the need for secondary processing, thus ensuring the efficiency and quality of the four-sided folding and welding process of the poncho and raincoat.

[0022] 2. Compared with existing technologies, the four-sided folding and welding edge processing mechanism for producing ponchos and raincoats facilitates continuous conveying of strip fabric by setting conveyor rollers; it enables the installation of buttons on the front and back sides of the fabric by setting a button attaching machine; it allows punching holes at the hood position of the fabric by setting a marking cylinder and a cold knife, making it easier to accurately position the hood during subsequent manual welding; and it restricts the lifting path of the electric cutting wire by setting a connecting guide rail, ensuring the stability of the electric cutting wire's movement.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1 to 5 This utility model provides a four-sided folding and welding edge processing mechanism for the production of ponchos and raincoats. The overall processing mechanism is electrically connected to the central control room of the external production workshop. It includes a frame 1. The inner wall of the frame 1 is provided with several conveying rollers 17 for supporting the fabric. From left to right, the frame 1 is provided with a feeding and correction mechanism 24, a folding edge mechanism, a hot welding edge mechanism, a hem speed buffer mechanism 18, a buttoning mechanism, a hem speed buffer mechanism 29, a hat position marking mechanism, a double hem folding edge mechanism, and two sets of robotic arm linkage gripping mechanisms 25 for pulling the fabric.

[0031] The four-sided folding and welding processing mechanism is used for the production of the poncho raincoat. The plastic fabric used to make the raincoat is conveyed from left to right on the surface of the frame 1.

[0032] The feeding and correction mechanism 24 consists of an air shaft, a correction device, a cylinder, and a series of mechanical structures. The air shaft passes through the inner tube of the original EVA fabric, and after inflation, it fixes the raw material. Then, through the correction device, it adjusts the front and rear positions of the fabric so that the folding amount on the front and rear sides of the fabric is consistent.

[0033] The folding mechanism is used to fold the front and back sides of the fabric. The folding mechanism includes a base plate 2 set on the surface of the frame 1. A folding piece 3 is set on the top of the frame 1 corresponding to the base plate 2. The front and back sides of the fabric are folded through the gap formed by the folding piece 3 and the base plate 2. The folding amount is adjusted by adjusting the position of the folding piece 3.

[0034] The hot welding edge mechanism includes a silicone roller 4 and a heating welding plate 5 set on the surface of the frame 1. The fabric is conveyed between the silicone roller 4 and the heating welding plate 5, and the front and back sides of the fabric are welded by heating the heating wire built into the heating welding plate 5.

[0035] The double hem folding mechanism includes two downward electric cylinders 6 or two downward air cylinders symmetrically arranged above the frame 1. Each pair of downward electric cylinders 6 forms a group. The telescopic end of each group of downward electric cylinders 6 is fixedly installed with a welding block 7. The welding block 7 has a built-in heating rod or a surface-mounted heating wire to heat the fabric. The surface of the frame 1 is provided with a welding fixing base 8 below the welding block 7, which provides bottom support for welding. The frame 1 is provided with a folding fixing block 9 and a synchronous wheel mechanism 10 above the frame 1. The folding fixing block 9 has a built-in vacuum pump vacuum system, which can make the fabric stick tightly to the folding fixing block 9. The surface of the synchronous wheel mechanism 10 is provided with a folding movable block 11.

[0036] It is worth noting that the downward electric cylinder 6 can be replaced with a downward pneumatic cylinder as needed for installation, and the downward pneumatic cylinder can be used to drive the welding block 7 to move up and down.

[0037] Furthermore, the heating rods or heating wires on the surface of the welding block 7 can be removed and transferred to the surface of the welding fixing base 8 to complete the welding action on the fabric.

[0038] The synchronous pulley mechanism 10 is a system consisting of a motor, a synchronous pulley, and a synchronous belt. The rotation of the motor drives the synchronous pulley to rotate, causing the folded edge movable block 11 to flip.

The pressing rod 16 is positioned corresponding to the pressing base 14.

[0040] During the conveying process, the front and rear sides of the fabric are folded and welded using a folding mechanism and a hot welding mechanism. Then, through a double-swing folding mechanism, the cutting cylinder 13 extends and drives the electric cutting wire 12 to move downward during the fabric conveying process, which can cut the fabric. The two folding movable blocks 11 are flipped to fold the ends of the fabric. Then, from right to left, the downward electric cylinder 6 drives the welding block 7 to move downward to weld the fabric, thereby achieving the purpose of folding and welding the left and right sides of the cut fabric. No secondary clamping and processing is required afterward, thus ensuring the efficiency and quality of the four-sided folding and welding process of the poncho raincoat.

[0041] The button attaching machine 20 includes a button attaching machine 20 that is fixedly installed on top of the frame 1.

[0042] By setting up the button attaching machine 20, it is possible to perform button attaching and installation processing on both the front and back sides of the fabric.

[0043] The hem speed buffer mechanism 18 and the hem speed buffer mechanism 29 are located on the left and right sides of the button attaching machine 20, respectively. The hem speed buffer mechanism 18 and the hem speed buffer mechanism 29 are used to adjust the speed of the fabric at the button attaching machine 20, thereby achieving the function of adjusting the button position.

[0044] The marking mechanism for the cap position includes a marking cylinder 21 fixedly installed on the top of the frame 1 and a cold knife 22 fixedly installed on the surface of the telescopic end of the marking cylinder 21. The marking cylinder 21 and the cold knife 22 punch holes in the cap position to facilitate accurate positioning during subsequent manual welding of the cap.

[0045] By setting up a marking cylinder 21 and a cold knife 22, holes can be punched at the cap position of the fabric, making it easier to accurately locate the cap during subsequent manual welding.

[0046] A connecting rail 23 is provided above the frame 1, and the electric cutting wire 12 is slidably connected to the inner wall of the connecting rail 23.

[0047] By setting the connecting guide rail 23, the lifting path of the electric cutting wire 12 can be restricted, ensuring the stability of the movement of the electric cutting wire 12.
