Description

Technical Field

[0001] The invention relates to the technical field of raincoat production, in particular to an automatic edge folding and button sewing raincoat cutting machine. Background Art

[0002] Raincoats are garments made of waterproof fabric, typically made from tape, tarpaulin, and plastic film, designed to protect against rain. To accommodate fast-paced lifestyles and the demand for portability and ease of use, disposable raincoats have emerged. They are often used temporarily in recreational venues to protect against sudden downpours. Disposable raincoats are typically disposable after a single use, leading to high demand. However, these raincoats are thin and easily damaged during the production process. Consequently, machines designed to automate their production have emerged.

[0003] For example, publication number "CN113303535A" discloses a raincoat manufacturing machine, which includes a frame, a flanging mechanism, a bonding mechanism, a sewing mechanism, a cutting mechanism, a cutting mechanism, a flanging heat-sealing mechanism, and a feeding mechanism to complete the production of raincoats. The bonding mechanism includes a pressing plate and a heating plate, which can cooperate to press the side edges of the raw material. The flanging heat-sealing mechanism is used to fold the end of the raincoat inward to form an end flange and fix the edge of the end flange to the raincoat. The flanging heat-sealing mechanism includes an air motor, the output end of the air motor is connected to a fixed frame, and the fixed frame is provided with a pressing member that can press the raincoat. A flap is rotatably provided on the frame, providing a driving source for the flap. The flap can rotate and drive the end of the raincoat to fold inward. A heating plate is fixedly mounted on the frame.

[0004] However, the above technical solution for raincoat sheet processing still has the following problems:

[0005] The folding heat-sealing mechanism is used to fold out the hem of the raincoat. However, due to the light weight of the raincoat material, there is a lack of support and tension during the folding process, which easily leads to wrinkles at the folding point, making the hem of the raincoat unsightly.

[0006] The flanging heat sealing mechanism is used to press the raincoat with a pressing part to prevent the raincoat from deflecting when folding. The pressing part adopts a pressing rope or a pressing wire. Since a pneumatic motor is used to drive the pressing rope or the pressing wire, the driving force of the pneumatic motor may be too large, causing the pressing rope or the pressing wire to break, and replacing the pressing rope or the pressing wire is also troublesome.

[0007] The electric heating plate lacks cooling function. If the hot pressing part is still in a high temperature state, the side may not be fully pressed and firmly pressed. In addition, during long-term use, continuous high temperature may easily cause the properties of the electric heating plate to change and shorten its service life.

[0008] The electric heating plate is powered on for heating, but the above technical solution lacks the function of detecting whether the electric heating plate is powered on, which may cause the electric heating plate to continue working in a power-off state, resulting in the production of raincoats with unbonded sides. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide an automatic hemming and buttoning raincoat cutting machine in view of the deficiencies of the above-mentioned prior art.

[0010] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic hem folding and buttoning raincoat cutting machine, comprising a feeding device, an hem folding and heat-sealing device, a buttoning device, a cutting device, and a hem folding device arranged in sequence; the hem folding device comprises a hem folding frame, a pulling mechanism and a folding mechanism installed on the hem folding frame, the folding mechanism comprises a lower folding plate and an upper folding plate, a folding space for the upper folding plate to move is provided between the lower folding plate and the upper folding plate, the upper folding plate is connected to a folding drive assembly for driving the upper folding plate to flip, the folding drive assembly comprises a folding drive source, a transmission member linked to the folding drive source, the upper folding plate is connected to one end of the transmission member, an anti-wrinkle mechanism is also provided on the transmission member, the anti-wrinkle mechanism comprises a pressing member, one end of the pressing member is connected to an anti-wrinkle drive assembly that can drive the pressing member to enter and exit the folding space.

[0011] By adopting the above technical solution, the feeding device of the present invention is used to transport raincoat raw materials, which are sequentially passed through the folding and heat-sealing device for folding and ironing the sides of the raincoat, passed through the button-stitching device for buttoning on the sides, passed through the cutting device for cutting the collar and cuffs and cutting into raincoat pieces, and the raincoat pieces are folded and ironed through the hem-folding device. In particular, the hem-folding device

[0012] An anti-wrinkle component is added to prevent the raincoat material from wrinkling when the folding component folds the hem. The driving source assembly drives the swing rod to swing so that after the pressing piece moves to a certain position, the pressing piece is driven to exit the folding space before the upper folding plate and the lower folding plate are completely pressed together with the lower hem, so as to avoid the pressing piece being wrapped around the folding part of the raincoat piece.

[0013] The above-mentioned automatic folding and buttoning raincoat cutting machine can be further configured as follows: a folding drive source is connected to a transmission gear, the folding drive source drives the transmission gear to rotate, the transmission part includes a gear part and a mounting part, the gear part is engaged with the transmission gear, and the mounting part is connected to the upper folding plate; the anti-wrinkle drive assembly includes an anti-wrinkle drive source connected to the mounting part, and a rotating shaft driven by the anti-wrinkle drive source and rotatable along its own axis, the rotating shaft passes through the mounting part and is rotatably arranged, one end of the rotating shaft is connected to a swing rod, and one end of the swing rod is connected to the pressing piece.

[0014] By adopting the above technical solution, the folding drive mechanism realizes the rotation of the transmission member by meshing the transmission gear with the gear part of the transmission member. When the transmission member rotates, the mounting part rotates accordingly, thereby driving the upper folding plate to flip. The meshing between the gears is used to ensure that the force on the transmission member is stable, and to avoid impact when the upper folding plate cooperates with the lower folding plate to press the hem. At the same time, the anti-wrinkle drive source of the anti-wrinkle drive assembly is connected to the mounting part, and the rotating shaft passes through the mounting part and is rotatable. That is, when the transmission member rotates, the anti-wrinkle drive assembly also rotates with the transmission member, and the anti-wrinkle drive assembly and the folding drive assembly can work simultaneously to optimize the movement path of the pressing member, so that the pressing member can quickly enter the folding space to provide support and pressing force for the folding position, and quickly move away from the folding space.

[0015] The above-mentioned automatic folding and buttoning raincoat cutting machine can be further configured as follows: the folding mechanism also includes a folding platform installed on the hem frame for folding the bottom hem, the lower folding plate and the upper folding plate are arranged at one end of the folding platform, and a plurality of exhaust holes are provided on the folding platform; the upper folding plate is connected to a vacuum adsorption component, the vacuum adsorption component includes a plurality of ventilation holes opened on the upper folding plate, the ventilation holes are connected to vacuum pipelines, and the ventilation holes are connected to a vacuum generator through the vacuum pipeline.

[0016] By adopting the above technical solution, the air between the raincoat piece and the lower folding plate can be discharged through the exhaust holes, avoiding the gas from being retained between the lower folding plate of the raincoat piece and causing the raincoat piece to wrinkle, so that the raincoat piece can be flatly attached to the folding platform; and a vacuum adsorption component is provided on the upper folding plate to replace the pressing part in the prior art. The vacuum adsorption component specifically includes a plurality of vents opened on the upper folding plate, and the vents are connected to a vacuum pipe and connected to a vacuum generator. The vacuum generator is used to extract the gas and adsorb one end of the raincoat piece on the upper folding plate, so that the one end of the raincoat piece will not be offset during the folding process of the upper folding plate; with the main body of the raincoat piece attached to the folding platform, the beautiful hem after pressing can be further ensured, thereby improving the production quality.

[0017] The above-mentioned automatic folding and buttoning raincoat cutting machine can be further configured as follows: the pulling mechanism includes a number of pulling manipulators and a pulling translation assembly for controlling the movement of the pulling manipulators; the pulling translation assembly includes a pulling slide rail installed on the folding and hemming frame, and a pulling slider movably arranged on the pulling slide rail; the pulling slider is provided with a mounting shaft, and the pulling manipulator is arranged on the mounting shaft; the pulling manipulator includes a manipulator body and a flattening drive cylinder that drives the manipulator body to move along the axial direction of the mounting shaft; one end of the mounting shaft is connected to a swing angle adjustment assembly for adjusting the swing angle of the pulling manipulator.

[0018] With the above technical solution, a mounting shaft for a material pulling manipulator is mounted on the material pulling slider. The material pulling slider moves on the material pulling rail, allowing the material pulling manipulator to pull the raincoat material to the folding mechanism. Multiple groups of material pulling manipulators can be provided, and a flattening drive cylinder can drive the manipulator body of the material pulling manipulator to move the two groups of material pulling manipulators away from each other, thereby flattening the material. The flattening drive cylinder can be activated or deactivated according to actual conditions. A swing angle adjustment assembly can drive the material pulling manipulator to swing by rotating the mounting shaft, thereby adjusting the material gripping position of the material pulling manipulator to facilitate gripping of the raincoat piece cut from the cutting device.

[0019] The above-mentioned automatic hemming and buttoning raincoat cutting machine can be further configured as follows: the swing angle adjustment component includes a swinging member with one end relatively fixedly connected to the mounting shaft and capable of rotating following the mounting shaft, the other end of the swinging member is hinged to a first telescopic rod, the first telescopic rod is linked to a first hydraulic cylinder that can drive the first telescopic rod to extend and retract, and the other end of the first hydraulic cylinder is hinged to the material pulling slider.

[0020] By adopting the above technical solution, the first hydraulic cylinder is used to control the movement of the first telescopic rod, so that the swinging part swings, and then drives the installation shaft to rotate to adjust the swing angle of the pulling robot; when there is a certain pressure in the first hydraulic cylinder, the first telescopic rod will not move easily, which can ensure that after the position of the pulling robot is adjusted, the installation shaft will no longer rotate at will.

[0021] The above-mentioned automatic hemming and buttoning raincoat cutting machine can be further configured as follows: the hemming and heat-sealing device includes a hemming and heat-sealing frame, a hemming mechanism installed on the hemming and heat-sealing frame for folding the two side edges of the raw material, and a pressing mechanism for ironing the folded two side edges; the pressing mechanism includes a mounting frame, a pressing strip, and a heat-sealing strip; the heat-sealing strip is arranged at one end of the mounting frame, the mounting frame is connected to the hemming and heat-sealing frame, the pressing strip is connected to a pressing cylinder for driving the pressing strip close to or away from the heat-sealing strip, the pressing cylinder is connected to the other end of the mounting frame, a cavity for cooling liquid to flow is provided in the heat-sealing strip, and the heat-sealing strip is provided with a liquid inlet and a liquid outlet communicating with the cavity at both ends of the cavity, the liquid inlet and the liquid outlet of the heat-sealing strip are connected to a cooling pipeline, and the cooling pipeline is connected to a cooling component; the cooling component includes a coolant storage box, and the coolant storage box is connected to a circulating pump.

[0022] By adopting the above technical solution, the heat sealing strip of the hemming heat sealing device of the present invention can be cooled by the cooling assembly. On the one hand, it can quickly cool the side pressing part to fix it into shape. On the other hand, it can prevent the heat sealing strip from changing its properties due to excessive temperature accumulation during the long-term heat pressing process. The hemming mechanism of the hemming heat sealing device is used to fold the side of the raincoat, and the pressing mechanism presses the side to form a placket. The pressing mechanism usually includes a pressing strip and a heat sealing strip. An electric heating wire is usually installed on the heat sealing strip. In the present invention, a cavity for the flow of coolant is provided in the heat sealing strip, and the heat sealing strip is provided with a liquid inlet and a liquid outlet at both ends of the cavity that are connected to the cavity. The liquid inlet and the liquid outlet are connected to the coolant storage box through a cooling pipeline. The coolant storage box is connected to a circulating pump. The circulating pump provides power for the circulation of the coolant, thereby realizing the circulation of the coolant into the cavity of the heat sealing strip, so that the heat sealing strip can be cooled in time.

[0023] The above-mentioned automatic hemming and buttoning raincoat cutting machine can be further configured as follows: a heating wire is installed on one side of the heat sealing strip, and a current sensor for detecting whether current passes through the heating wire is installed on the hemming and heat sealing frame.

[0024] In this technical solution, a current sensor detects whether current is flowing through the heating wire. If the sensor detects no current during the hot pressing process, indicating a short circuit, the wire is disconnected. The sensor generates or cuts off a signal, prompting the controller (a raincoat manufacturing machine typically includes a controller to coordinate the operation of various devices, typically a computer) to promptly stop the machine for maintenance. If the sensor detects current during the hot pressing process, the heating wire is functioning properly. This prevents the pressing mechanism from operating ineffectively when the heating wire is disconnected, thus preventing the production of substandard products.

[0025] The above-mentioned automatic hemming and buttoning raincoat cutting machine can be further configured as follows: a spacing adjustment mechanism for adjusting the spacing between the two pressing mechanisms is provided between the pressing mechanism and the hemming and heat sealing frame, the spacing adjustment mechanism includes an adjusting member, an adjusting slide rail installed on the hemming and heat sealing frame, and a sliding plate connected to the mounting frame, and the sliding plate is slidably arranged along the adjusting slide rail; the adjusting member is arranged through the hemming and heat sealing frame and the sliding plate and is threadedly connected to the hemming and heat sealing frame and the sliding plate, and a locking member that can limit the rotation of the adjusting member is provided between the adjusting member and the hemming and heat sealing frame.

[0026] Using the above technical solution, a spacing adjustment mechanism is used to adjust the spacing between the two pressing mechanisms to accommodate the production of raincoats of different specifications. The spacing adjustment mechanism includes an adjustment rail and a sliding plate. The sliding plate is connected to the mounting frame, allowing the pressing mechanism, mounted on the sliding plate, to follow the movement of the sliding plate. The adjustment member is threadedly connected to the hemming and heat-sealing frame and the sliding plate. When the adjustment member is rotated, the sliding plate moves laterally relative to the hemming and heat-sealing frame, as the hemming and heat-sealing frame is relatively fixed, thereby adjusting the spacing between the two pressing mechanisms. A locking member is provided to restrict the adjustment member from further rotation in the absence of external force after adjustment is completed, thereby maintaining the spacing between the two pressing mechanisms.

[0027] The above-mentioned automatic folding and buttoning raincoat cutting machine can be further configured as follows: the cutting device includes a cutting frame, an upper cutting plate, a lower cutting plate, a cutting drive source for driving the upper and lower cutting plates close to each other, and a cutting mechanism for cutting the raincoat material into pieces; the upper cutting plate is provided with a cuff cutting die and a collar cutting die, and the lower cutting plate is provided with a discharge trough at the position corresponding to the cuff cutting die and the collar cutting die, and a turning mechanism is provided below the lower cutting plate at the position corresponding to the cuff cutting die and the collar cutting die, and a waste discharge mechanism is provided below the turning mechanism, and the waste discharge mechanism includes guide plates arranged opposite to each other mounted on the cutting frame, and the two guide plates are arranged close to each other and inclined below, and a waste conveyor belt assembly is provided below the guide plate, and the cutting frame is provided with a waste outlet at one end of the waste conveyor belt assembly.

[0028] By adopting the above technical solution, the cutting device drives the upper cutting plate and the lower cutting plate to cooperate through the cutting drive source to realize the cutting of the cuffs and collars. The waste after cutting is discharged from the discharge chute through the turning mechanism and enters the waste discharge mechanism. The waste discharge mechanism includes a guide plate and a waste conveyor belt assembly. The guide plate collects the waste to the waste conveyor belt assembly, and the waste conveyor belt assembly sends it to the waste outlet for concentration, so as to avoid the waste from accumulating in the cutting machine frame for easy cleaning.

[0029] The above-mentioned automatic folding and buttoning raincoat cutting machine can be further configured as follows: the turning mechanism includes a turning plate hinged to the lower cutting plate, the turning plate cover is arranged below the discharge trough, a second telescopic rod is hinged to the middle part of the turning plate, the second telescopic rod is linked to a second hydraulic cylinder that can drive the second telescopic rod to extend and retract, and one end of the second hydraulic cylinder is hinged to the lower cutting plate; when the second hydraulic cylinder drives the second telescopic rod to retract, the second telescopic rod can drive the turning plate to rotate and open the discharge trough.

[0030] Using the above technical solution, the turning mechanism is set at the positions corresponding to the cuff cutting die and the collar cutting die. The cut waste can fall on the turning plate through the discharge chute. The turning mechanism drives the second telescopic rod to retract through the second hydraulic cylinder, and then drives the turning plate to rotate and open the discharge chute, so that the waste can fall into the waste discharge assembly through the discharge chute.

[0031] The beneficial effects of the present invention are as follows: providing an automatic hem folding and buttoning raincoat cutting machine, firstly, an anti-wrinkle component is added to the hem folding device, and the pressing piece of the anti-wrinkle component can cooperate with one end of the lower folding plate to fold the raincoat material when the upper folding plate is turned under the action of the folding driving component to fold the hem of the raincoat material. The anti-wrinkle driven pressing piece provides support and pressing force for the raincoat piece at the folding position, so as to avoid the raincoat material being deformed due to lack of support when folding, resulting in wrinkles after folding and pressing, and the pressing piece is promptly withdrawn from between the upper folding plate and the lower folding plate under the drive of the anti-wrinkle driving component; secondly, the hem folding device is also provided with a vacuum adsorption component for adsorbing the hem of the raincoat piece and folding it, so as to avoid deviation during the hem folding process and improve the stability of the equipment; finally, the heat sealing strip of the edge heat sealing device is connected to the cooling group, which can quickly cool the side edge pressing position to fix it into shape, and avoid excessive temperature accumulation causing changes in the properties of the heat sealing strip; the edge heat sealing device is also provided with a heating wire power-off detection mechanism, which can effectively prevent the equipment from continuing to work and producing unqualified products when the heating wire is powered off.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0053] like Figures 1 to 19 The automatic hem folding and buttoning raincoat cutting machine shown in the figure comprises a feeding device 1, an hem folding and heat-sealing device 2, a buttoning device 3, a cutting device 4, and a hem folding device 5 which are arranged in sequence. In the present invention, raincoat raw materials are discharged through the feeding device 1 and processed into raincoat pieces through the hem folding and heat-sealing device 2, the buttoning device 3, the cutting device 4, and the hem folding device 5 in sequence. The present invention is used to produce raincoat pieces, and the raincoat pieces can be made into raincoats after entering the subsequent sewing step.

[0054] like Figures 2 to 6 The figure shows the folding and heat-sealing device 2 of the present invention, which includes a folding and heat-sealing frame 21, a folding mechanism 22, and a pressing mechanism 23 for ironing the folded two sides. The folding mechanism 22 of the present invention can utilize the existing folding mechanism 22 for folding, and may include a folding roller, an upper folding plate and a lower folding plate. The raincoat raw material passes through the folding roller and enters between the upper folding plate and the lower folding plate for folding, which will not be described in detail here. The pressing mechanism 23 usually includes a pressing strip 231, a heat sealing strip 232, a mounting frame 233, and is provided with a pressing cylinder 234. The heat sealing strip 232 and the pressing cylinder 234 are respectively arranged at the upper and lower ends of the mounting frame 233, and the pressing cylinder 234 can drive the pressing strip 231 to move closer to or away from the heat sealing strip 232; a heating wire 235 is installed on the heat sealing strip 232, and the heating wire 235 is connected to a current sensor 236. The current sensor 236 is installed on the folding heat sealing frame 21, and the heating wire 235 is arranged to pass through the detection area of the current sensor 236 so that the current sensor 236 can detect whether there is current passing through the heating wire 235.

[0055] The heat sealing strip 232 is provided with a cavity 2321 for the flow of coolant, and the heat sealing strip 232 is provided with a liquid inlet hole 2322 and a liquid outlet hole 2323 communicating with the cavity 2321. Figure 4 As shown, the liquid inlet 2322 and the liquid outlet 2323 are connected to the coolant storage box 237 via a cooling pipe 239. The coolant storage box 237 is connected to a circulation pump 238. The circulation pump 238 can provide power for the circulation of the coolant. The coolant can enter and exit the cavity 2321 of the heat seal strip 232 through the cooling pipe 239, the liquid inlet 2322, and the liquid outlet 2323 to be cooled. On the one hand, it can quickly cool the side press-fitting area to fix it into shape. On the other hand, it can prevent the heat seal strip 232 from changing its properties due to excessive temperature accumulation during the long heat pressing process.

[0056] The present invention provides a spacing adjustment mechanism 24 between the pressing mechanism 23 and the hem folding and heat sealing frame 21. The spacing adjustment mechanism 24 includes an adjusting member 241, an adjusting slide rail 242 installed on the hem folding and heat sealing frame 21, and a sliding plate 243 connected to the mounting frame 233. The adjusting member 241 passes through the hem folding and heat sealing frame 21 and the sliding plate 243 and is threadedly connected to the hem folding and heat sealing frame 21 and the sliding plate 243. By rotating the adjusting member 241, the sliding plate 243 is displaced along the adjusting slide rail 242 relative to the hem folding and heat sealing frame 21, thereby changing the spacing between the two pressing mechanisms 23 to complete the side hem folding and heat sealing task of raincoats of different specifications. A locking member 244 is provided between the adjusting member 241 and the folding and heat sealing frame 21 to limit the rotation of the adjusting member 241. After the adjustment is completed, the locking member 244 can prevent the adjusting member 241 from continuing to rotate without external force to maintain the distance between the two pressing mechanisms 23. In this embodiment, the locking member 244 is a fastening screw.

[0057] The button sewing device 3 mainly includes a button sewing machine and a transport roller group. The button sewing machine can adopt an existing button sewing machine, which is used to make raincoat buttons on the side of the folded raincoat raw material (i.e., the raincoat placket part), so it is not described in detail here.

[0058] like Figures 7 to 10 The cutting device 4 is shown, which includes a cutting frame 41, an upper cutting plate 42, a lower cutting plate 43, a cutting drive source 47 for driving the upper and lower cutting plates close to each other, and a cutting mechanism 46 for cutting the raincoat material into pieces. In this embodiment, the cutting drive source 47 adopts a cylinder, and the cutting mechanism 46 can adopt existing technology, so it is not repeated; the upper cutting plate 42 is provided with a cuff cutting die 421 and a collar cutting die 422. The upper cutting plate 42 cooperates with the lower cutting plate 43 to cut sleeves on the raincoat material. The cut waste enters the discharge chute 431 provided on the lower cutting plate 43. The discharge chute 431 is opened at a position corresponding to the cuff cutting die 421 and the neckline cutting die 422. A turning mechanism 44 is provided below the lower cutting plate 43 corresponding to the discharge chute 431. In the present invention, the turning mechanism 44 includes a turning plate 441 hinged to the lower cutting plate 43. The turning plate 441 is covered below the discharge chute 431. When the waste enters the discharge chute 431, it is blocked by the turning plate 441.

[0059] A second telescopic rod 442 is hingedly connected to the middle of the flipping plate 441, and the second telescopic rod 442 is linked to a second hydraulic cylinder 443 that can drive the second telescopic rod 442 to extend and retract. One end of the second hydraulic cylinder 443 is hinged to the lower cutting plate 43; when the second hydraulic cylinder 443 drives the second telescopic rod 442 to retract, it drives the flipping plate 441 to rotate, thereby opening the discharge chute 431, so that the waste continues to fall; a waste discharge mechanism 45 is provided below the flipping mechanism 44, and the waste discharge mechanism 45 includes a Guide plates 451 are mounted on the cutting frame 41 and are positioned opposite each other. The guide plates 451 are angled and positioned close to each other. A waste conveyor belt assembly 452 is positioned below the guide plates 451. Waste is collected on the waste conveyor belt assembly 452. A waste outlet 411 is provided at one end of the waste conveyor belt assembly 452 on the cutting frame 41. The waste conveyor belt assembly 452 conveys waste to the waste outlet 411, preventing waste from accumulating within the cutting frame 41 and facilitating its removal. The waste conveyor belt assembly 452 can be an existing conveyor belt structure and is not described in detail here.

[0060] In particular, if Figures 11 to 19 As shown, the hem folding device 5 includes a hem folding frame 51 , a material pulling mechanism 52 , a folding mechanism 53 , and a material stacking mechanism 54 .

[0061] Among them, the material pulling mechanism 52 includes a plurality of material pulling manipulators 522 and a material pulling translation component 521 for driving the material pulling manipulator 522 to move. The material pulling translation component 521 includes a material pulling slide rail 5211 installed on the folding swing frame 51 and a material pulling slider 5212 movably arranged on the material pulling slide rail 5211. The material pulling slider 5212 is provided with a mounting shaft 5213. The material pulling manipulator 522 is arranged on the mounting shaft 5213. The material pulling manipulator 522 includes a manipulator body 5221 and a flattening drive cylinder 5222 that drives the manipulator body 5221 to move along the axial direction of the mounting shaft 5213; one end of the mounting shaft 5213 is connected to a swing angle adjustment component for adjusting the swing angle of the material pulling manipulator 522. The swing angle adjustment component of the present invention includes one end connected to the mounting shaft 521 3, so that the swing member 5214 can rotate along with the installation shaft 5213. The other end of the swing member 5214 is hingedly connected to a first telescopic rod 5215. The first telescopic rod 5215 is linked to a first hydraulic cylinder 5216 that can drive the first telescopic rod 5215 to extend and retract. The other end of the first hydraulic cylinder 5216 is hingedly connected to the material pulling slider 5212. The first hydraulic cylinder 5216 drives the first telescopic rod 5215 to extend and retract, driving the swing member 5214 to swing, and further driving the installation shaft 5213 to rotate to adjust the swing angle of the material pulling robot 522. After the adjustment is completed, when the first hydraulic cylinder 5216 maintains a certain pressure, the first telescopic rod 5215 will not move easily, thereby ensuring that the installation shaft 5213 will no longer rotate arbitrarily after the position of the material pulling robot 522 is adjusted.

[0062] The folding mechanism 53 includes a folding platform 538, a lower folding plate 531, and an upper folding plate 532. The folding platform 538 is also provided with an exhaust hole 5381, through which air between the lower folding plate 531 of the raincoat piece can be discharged, preventing air from being trapped between the lower folding plate 531 of the raincoat piece and causing wrinkles in the raincoat piece. The upper folding plate 532 is connected to a vacuum suction assembly, replacing the pressing member used in the prior art. The vacuum suction assembly includes a plurality of vents 5321 formed on the upper folding plate 532. The vents 5321 are connected to a vacuum line 533, which in turn is connected to a vacuum generator 534 via the vacuum line 533. The upper folding plate 532 is connected to a folding drive component that drives the upper folding plate 532 to flip. A folding space for the upper folding plate 532 to move is provided between the lower folding plate 531 and the upper folding plate 532. The vacuum generator 534 is used to extract gas to adsorb one end of the raincoat piece onto the upper folding plate 532. When the folding drive component drives the upper folding plate 532 to rotate, the end of the raincoat piece is adsorbed onto the upper folding plate 532, thereby preventing the end of the raincoat piece from being offset.

[0063] The folding drive assembly includes a folding drive source 535 and a transmission member 536. The folding drive source 535 is connected to a transmission gear 537. The transmission member 536 includes a gear portion 5361 and a mounting portion 5362. The transmission gear 537 is meshed with the gear portion 5361 of the transmission member 536. The mounting portion 5362 is connected to the upper folding plate 532, and the upper folding plate 532 is driven to move by gear meshing, thereby ensuring that the transmission member 536 is subjected to stable force. The mounting portion 5362 is also provided with an anti-wrinkle mechanism 55, which includes a pressing piece 551 and an anti-wrinkle drive assembly for driving the pressing piece 551 in and out of the folding space. The anti-wrinkle drive assembly includes an anti-wrinkle drive source 552 connected to the mounting portion 5362, and a rotating shaft 553 driven by the anti-wrinkle drive source 552 and capable of rotating along its own axis. The rotating shaft 553 passes through the mounting portion 5362 and is rotatably arranged. One end of the rotating shaft 553 is connected to a swing rod 554, and one end of the swing rod 554 is connected to the pressing piece 551. The pressing piece 551 of the present invention can be made of steel wire, and the axis of the swing rod 554 is perpendicular to the axis of the rotating shaft 553, and the axis of the swing rod 554 is perpendicular to the axis of the pressing piece 551. The folding drive source 535 and the anti-wrinkle drive source 552 can be motors.

[0064] The stacking mechanism 54 mainly includes a stacking platform 541, a stacking robot 542, and a stacking translation assembly 543. The three can adopt existing technologies, so they are not described in detail. The stacking robot 542 clamps the raincoat piece with the folded hem, and the stacking robot 542 is moved through the stacking translation assembly 543 to stack the raincoat piece on the stacking platform 541.

[0065] The working principle of the present invention is:

[0066] The raincoat raw material roll is placed on the feeding device 1, and the material passes through the folding and heat-sealing device 2, the button-stitching device 3, the cutting device 4, and the hem folding device 5 in sequence.

[0067] When the material passes through the folding mechanism 22, the two sides are ironed by the pressing mechanism 23. In the pressing mechanism 23, the material enters between the pressing strip 231 and the heat-sealing strip 232. The heating wire is energized, and the pressing cylinder drives the pressing strip 231 close to the heat-sealing strip 232 to realize the pressing of the side of the raincoat; then the material enters the buttoning device 3, and the buttoning machine 31 of the buttoning device 3 buttons the side of the raincoat. Then the material enters the cutting device 4, and the cutting drive source 47 drives the upper and lower cutting plates to approach each other, and the cuff cutting die 421 and the collar cutting die 422 on the upper cutting plate 42 are used to cut the material. After the cuffs and collar are cut, the cut waste material falls into the discharge chute 431. The second hydraulic cylinder 443 drives the second telescopic rod 442, which rotates the material flipper to open the discharge chute 431. The waste material passes through the guide plate 451 and falls onto the waste conveyor belt assembly 452, which then conveys the waste material to the waste outlet 411. The pulling mechanism 52 of the hem folding device 5 then clamps one end of the material. The flattening drive cylinder 5222 drives the manipulator body 5221 of the pulling mechanism 522 to move the two sets of pulling mechanisms 522 away from each other, thereby flattening the material. In this embodiment, three sets of two pulling mechanisms 522 are provided, with the two sets of pulling mechanisms 522 on both sides being equipped with flattening drive cylinders 5222.

[0068] Then, the material is pulled by the material pulling and translation assembly 521 so that one end of the material enters the folding space. After the material is pulled into place by the material pulling mechanism 52, the cutting mechanism 46 of the cutting device 4 cuts the material into sheets.

[0069] In the initial state of the folding mechanism 53, the angle a between the lower folding plate 531 and the upper folding plate 532 is 180 degrees. After the material is in place, the vacuum generator 534 works, so that the upper folding plate 532 absorbs one end of the raincoat material, and then the folding drive source 535 drives the transmission member 536 to rotate so that the upper folding plate 532 flips toward the lower folding plate 531. At this time, the anti-wrinkle mechanism 55 follows the movement of the transmission member 536, and the anti-wrinkle drive source 552 drives the rotating shaft 553, the swing rod 554, the pressing member 551, etc. to move, so that the pressing member 551 enters the folding space, so that the folding part of the raincoat material is affected. The restriction of the pressing piece 551 causes the raincoat material to be folded along the pressing piece 551, providing support and pressing force to the raincoat piece at the folded part, so as to avoid the raincoat material being deformed due to lack of support when folding, resulting in wrinkles after folding and pressing, thereby ensuring the beauty of the produced raincoat; as the upper folding plate 532 continues to approach the lower folding plate 531, the angle a between the lower folding plate 531 and the upper folding plate 532 gradually decreases, the folding space gradually shrinks, and the anti-wrinkle driving source 552 drives the pressing piece 551 to exit the folding space, preventing the pressing piece 551 from being wrapped around the folded part of the raincoat piece and digging into the folded hem. The movement process of the pressing piece 551 is as follows: Figure 19 As shown in the dotted line part.

[0070] Then the stacking robot 542 grabs or absorbs the raincoat piece, and the stacking translation component 543 drives the stacking robot 542 to move and stack the raincoat piece on the stacking platform 541.
