Description

Technical Field

[0001] The invention particularly relates to a fully automatic non-woven vest apron machine. Background Art

[0002] Aprons are a common protective product widely used in many industries such as catering, medical treatment, and cleaning. Although existing aprons have certain functionality and portability, they can only cover the front of the body and cannot protect the back. In scenarios where front and back protection is required, the back cannot be effectively prevented from being soiled or contaminated.

[0003] In order to overcome the shortcomings of existing aprons, a non-woven vest apron with protection on both the front and back is specifically designed. The non-woven vest apron is mainly composed of a front body and a back body, and straps need to be processed on both sides. If necessary, pockets need to be processed on the non-woven vest apron. Since non-woven vest aprons are mostly disposable consumables and the demand is large, if they are only produced manually, the efficiency is extremely low, so it is necessary to design a dedicated fully automatic non-woven vest apron machine. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a fully automatic non-woven vest apron machine in view of the deficiencies of the above-mentioned prior art. Dual automatic feeding, cutting, hot welding and other devices are integrated and linked to complete the whole process production of aprons from raw materials to finished non-woven vest aprons. The front and rear panels of the vest apron are detachably connected to cover the chest, abdomen and back areas, solving the defect that traditional aprons only protect the front side. It is suitable for medical, cleaning and other scenarios where back contamination needs to be prevented.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic non-woven vest apron machine, comprising a frame, characterized in that: the frame is equipped with a double automatic loading device for transporting an upper film cloth and a lower film cloth, a bag feeding and cutting device for transporting the bag mouth film cloth and cutting the bag mouth film cloth into a single bag mouth, a bag mouth hot welding device for fixing a single bag mouth to an upper film cloth or a lower film cloth, a pressing and traction device for stacking and hot welding the upper film cloth and the lower film cloth, a strap cutting device for cutting out straps, and an integrated collar cutting device for cutting out collars and cutting the continuous film cloth into a single vest apron.

[0006] With the above technical solution, the double automatic feeding device synchronously conveys the upper layer of fabric and the lower layer of fabric to ensure continuous material supply. The bag mouth feeding and cutting device cuts the bag mouth fabric into single pieces, and after precise positioning, it is thermally pressed and fixed at the designated position (such as the chest or waist) of the upper or lower layer of fabric through the bag mouth hot welding device. The pressing and traction device aligns and stacks the upper and lower layers of fabric to form a composite fabric, and the shoulders are welded by hot pressing (the two sides of the composite fabric are not welded here) to form an integrated apron body for the front and back. The strap cutting device cuts out strip-shaped straps on both sides of the composite fabric. The neckline cutting and integral device cuts out an arc-shaped neckline and at the same time cuts the continuous fabric into single-piece finished products to complete the separation of the vest apron. The entire process transfers materials through mechanical traction, and each device collaborates to complete processes such as cutting, welding, and shaping without manual intervention. This solution forms a vest-style apron with a detachable connection between the front and back bodies by pressing the upper and lower layers of fabric, covering the chest, abdomen, and back areas, solving the defect that traditional aprons only protect the front, and is suitable for scenarios such as medical treatment and cleaning that require protection against back contamination. The double automatic feeding, cutting, hot welding and other devices are integrated and linked to complete the full-process production of the apron from raw materials to finished products, with the efficiency increased by dozens of times compared to manual work, meeting the large-scale demand for disposable consumables.

[0007] The above-mentioned fully automatic non-woven fabric vest apron machine can be further set as follows: The double automatic feeding device includes a material passing frame and an upper fabric transporting mechanism and a lower fabric transporting mechanism respectively arranged at both ends of the material passing frame. The upper fabric transporting mechanism includes a first swing arm, a fabric unwinding roller, and a first cylinder. One end of the first swing arm is hinged to the machine frame, and the other end is provided with a bayonet. The end of the fabric unwinding roller is rotatably installed at the bayonet. One side of the body of the first cylinder is hinged to the middle of the first swing arm, and the other side of the body of the first cylinder is hinged to a support block. Both ends of the support block are fixedly connected with support rods, and the support rods are fixed to the first swing arm. The output end of the first cylinder is hinged to a positioning block, and the positioning block is fixed to the machine frame. A magnetic powder clutch is installed on the first swing arm, and the output end of the magnetic powder clutch is linked with the fabric unwinding roller through a first transmission gear set; the upper fabric transporting mechanism and the lower fabric transporting mechanism have the same structure. The upper layer of fabric transported by the upper fabric transporting mechanism passes through the upper part of the material passing frame and is transported forward, and the lower layer of fabric transported by the lower fabric transporting mechanism is transported forward from under the end of the material passing frame.

[0008] With the above technical solution, first, the upper and lower layer fabric are guided by the spatial layering of the material passing rack (the upper layer passes through the top and the lower layer passes through the bottom), avoiding interference between the upper and lower layer fabric and saving space at the same time. Secondly, the material conveying mechanisms of the upper and lower fabric are both equipped with magnetic powder clutches, which can independently adjust the feeding speed and tension of each layer of fabric, ensuring that the double-layer fabric is synchronously aligned in a complex transportation path and avoiding deviation or wrinkles. Among them, the first cylinder pushes the first swing arm to swing around the hinge point through telescopic movement, adjusting the position of the fabric feeding roller and also controlling the tension of the fabric; further, when the fabric breaks or the feeding ends, the magnetic powder clutch immediately cuts off the power, and the feeding roller stops rotating. At the same time, the first cylinder pushes the swing arm to reset to the initial position, and through the bayonet, rapid roll change is achieved. Moreover, the material conveying mechanisms of the upper fabric and the lower fabric adopt exactly the same structure, with good interchangeability, facilitating rapid replacement and repair. Among them, the support rod connects the first swing arm and the support block, forming a stable triangular frame, enhancing the bending stiffness of the first swing arm during dynamic swinging and preventing deformation of the first swing arm caused by fabric tension or cylinder thrust. The thrust of the first cylinder is transmitted to the first swing arm through the support rod, reducing the local stress concentration at the hinge point of the first swing arm and prolonging the service life of the first swing arm.

[0009] The above-mentioned fully automatic non-woven fabric vest and apron machine can be further set as follows: The bag mouth feeding and cutting device includes a bag mouth film cloth feeding roller, a bag mouth cutting knife roller mechanism for cutting the bag mouth film cloth into single-piece bag mouths, and a bag mouth welding roller mechanism for welding the single-piece bag mouths onto the lower-layer film cloth. A transfer and smoothing mechanism is arranged between the bag mouth cutting knife roller mechanism and the bag mouth welding roller mechanism for transporting the single-piece bag mouths from the bag mouth cutting knife roller mechanism to the bag mouth welding roller mechanism; The bag mouth cutting knife roller mechanism includes an upper cutting knife roller and a bag mouth cutting cooperation roller respectively arranged on the upper and lower sides of the bag mouth film cloth. The outer peripheral surface of the upper cutting knife roller is provided with bag mouth cutting edges arranged along the axial direction of the upper cutting knife roller, and avoidance planes arranged at intervals with the bag mouth cutting edges and arranged along the axial direction of the upper cutting knife roller. The end of the bag mouth cutting cooperation roller is linked with a first servo motor through a first chain drive assembly, and the end of the upper cutting knife roller is linked with the end of the bag mouth cutting cooperation roller through a second transmission gear set; The transfer and smoothing mechanism includes a driving belt and a number of driven belts arranged at intervals and jointly distributed above the driving belt. The end of the driven belt is linked with a driven roller, the end of the driving belt is linked with a driving roller, the end of the driven roller is linked with one end of the driving roller through a third transmission gear set, and the other end of the driving roller is linked with a second servo motor through a second chain drive assembly; The bag mouth welding roller mechanism includes a bag mouth welding roller and a bag mouth ultrasonic welding head arranged opposite to each other up and down. The end of the bag mouth welding roller is linked with a third chain drive assembly through a fourth transmission gear set, the third chain drive assembly is linked with a third servo motor, and the outer peripheral surface of the bag mouth welding roller is provided with bag mouth welding edges for welding the two sides and the bottom edge of the bag mouth; A first guiding and traction roller group is arranged between the transfer and smoothing mechanism and the bag mouth welding roller mechanism for guiding and pulling the lower-layer film cloth and the single-piece bag mouths into the bag mouth welding roller mechanism for bag mouth welding.

[0010] With the above technical solution, the bag mouth film cloth feeding roller transports the bag mouth film cloth in an orderly manner. The bag mouth film cloth first passes through the bag mouth cutting knife roller mechanism. The first servo motor drives the bag mouth cutting and cooperating roller to rotate through the first chain drive assembly. The bag mouth cooperating roller drives the upper cutting knife roller through the second transmission gear set, realizing synchronous reverse rotation of the two rollers and completing the periodic cutting action. The bag mouth cutting edge on the surface of the upper cutting knife roller is used for cutting, and the avoidance plane on its surface rotates to correspond to the film cloth after cutting, avoiding secondary contact with the bag mouth film cloth. The single-piece bag mouth then passes through the transfer and flattening mechanism. The driving belt rotates the driving roller driven by the second servo motor. The driven belt is linked with the driving roller through the third transmission gear set, realizing synchronous movement of multiple groups of belts. The cut single-piece bag mouth is clamped between the belts and smoothly transported to the next working station through friction. The multiple groups of belts are arranged at intervals to form a "segmented flattening" effect, eliminating the wrinkles generated by cutting or transportation of the bag mouth. The first guiding and traction roller group is used to traction the single-piece bag mouth and the lower-layer film cloth, press the single-piece bag mouth onto the lower-layer film cloth, and synchronously traction the two into the bag mouth welding mechanism. The third servo motor drives the welding roller to rotate through the third chain drive assembly and the fourth transmission gear set, ensuring that the welding speed is synchronous with the bag mouth transportation speed and avoiding dislocation. The bag mouth welding roller surface is provided with a bag mouth welding edge for positioning the welding paths on both sides and the bottom edge of the bag mouth; the ultrasonic welding head generates heat through high-frequency vibration and fuses the bag mouth and the lower-layer film cloth through pressure.

[0011] The above-mentioned fully automatic non-woven fabric vest apron machine can be further set as follows: the pressing and traction device includes a shoulder welding roller mechanism and a second guiding and traction roller group. The second guiding and traction roller group is distributed between the shoulder welding roller mechanism and the bag mouth welding roller mechanism, and the second guiding and traction roller group is used to traction the upper-layer film cloth and the lower-layer film cloth with the bag mouth welded thereon into the shoulder welding roller mechanism; the shoulder welding roller mechanism includes a shoulder welding roller and a shoulder ultrasonic welding head arranged opposite to each other up and down. The end of the shoulder welding roller is linked with a fourth chain drive assembly through a fifth transmission gear set. The fourth chain drive assembly is linked with a fourth servo motor. The outer peripheral surface of the shoulder welding roller is provided with a shoulder welding edge for welding the shoulders.

[0012] With the above technical solution, the second guiding and traction roller group is used to traction the upper-layer film cloth and the lower-layer film cloth with the bag mouth welded thereon, and press the upper-layer film cloth and the lower-layer film cloth with the bag mouth welded thereon together up and down to form a composite film cloth, and synchronously traction it into the shoulder welding roller mechanism. The fourth servo motor drives the fifth transmission gear set through the fourth chain drive assembly, driving the shoulder welding roller to rotate at a constant speed, ensuring that the welding speed is synchronous with the traction speed and avoiding welding dislocation. When the composite film cloth with the bag mouth welded thereon passes through the gap between the shoulder welding roller and the shoulder ultrasonic welding head, the shoulder welding edge defines the welding area, and the ultrasonic energy penetrates the film cloth to achieve rapid welding.

[0013] The above-mentioned fully automatic non-woven fabric vest apron machine can be further set as follows: A triangular folding device for folding the composite fabric formed by laminating the upper fabric and the lower fabric with a pocket mouth welded thereon is provided between the pressing and traction device and the strap cutting device. The triangular folding device includes a triangular plate in the shape of an isosceles triangle. Above the top angle of the triangular plate, two sets of folding and pressing rollers are relatively distributed. At the bottom of the triangular plate, a fabric stacking feeding roller is provided. The folding and pressing rollers and the fabric stacking feeding roller are perpendicular to each other in different planes.

[0014] With the above technical solution, the composite fabric (with pockets welded and shoulders welded) passes through the fabric stacking feeding roller and the triangular plate in sequence and then enters between the two sets of folding and pressing rollers to complete folding.

[0015] The above-mentioned fully automatic non-woven fabric vest apron machine can be further set as follows: The strap cutting device includes a strap cutting roller and a strap cutting cooperating roller which are arranged oppositely up and down. On the outer peripheral surface of the strap cutting roller, a strap cutting edge for cutting the strap is provided. The end of the strap cutting cooperating roller is linked with a fifth servo motor through a fifth chain drive assembly. The end of the strap cutting roller is linked with the end of the strap cutting cooperating roller through a sixth transmission gear set.

[0016] With the above technical solution, the folded composite fabric passes through the gap between the strap cutting roller and the strap cutting cooperating roller from the upstream process (triangular folding device) in a flat state. The fifth servo motor drives the strap cutting cooperating roller to rotate through the fifth chain drive assembly. The cutting cooperating roller drives the strap cutting roller through the sixth transmission gear set, so that the two rollers rotate in opposite directions to cut the straps on the front and back sides.

[0017] The above-mentioned fully automatic non-woven fabric vest apron machine can be further set as follows: The neckline cutting and separating device includes a neckline cutting roller and a neckline cutting cooperating roller which are arranged oppositely up and down. On the outer peripheral surface of the neckline cutting roller, a neckline cutting edge for cutting the neckline and a cutting edge for cutting the continuous composite fabric with the neckline cut into single-piece vests and aprons are provided. The end of the neckline cutting cooperating roller is linked with a sixth servo motor through a sixth chain drive assembly. The end of the neckline cutting roller is linked with the end of the neckline cutting cooperating roller through a seventh transmission gear set. On one side of the neckline cutting roller away from the strap cutting device, a waste suction pipe is provided, and the waste suction pipe is connected with a fan assembly.

[0018] With the above technical solution, the continuous composite fabric that has completed strap cutting and folding enters the gap between the neckline cutting roller and the cooperating roller. The sixth servo motor drives the neckline cutting cooperating roller to rotate through the sixth chain drive assembly. The neckline cutting cooperating roller drives the neckline cutting roller through the seventh transmission gear set to ensure that the two rollers rotate in opposite directions, and continuous cutting and separation are realized by using the neckline cutting edge and the cutting edge. The fan assembly adsorbs the neckline waste through the waste suction pipe and transports it to the waste collection device.

[0019] The above-mentioned fully automatic non-woven fabric vest apron machine can be further configured as follows: a cloth stacking device is arranged on one side of the neckline cutting and integrating device away from the strap cutting device. The cloth stacking device includes a first feeding belt and a second feeding belt which are arranged opposite to each other left and right. The rotating directions of the first feeding belt and the second feeding belt are the same. One end of the first feeding belt is connected to the discharging side of the neckline cutting and integrating device. There is a vertical cloth stacking gap between the other end of the first feeding belt and the second feeding belt. Above the vertical cloth stacking gap, there is a first inserting plate and a lifting driving mechanism linked to the first inserting plate. A third feeding belt is arranged below the second feeding belt. The rotating direction of the third feeding belt is opposite to that of the second feeding belt. The vertical cloth stacking gap extends between the first feeding belt and the third feeding belt. A fourth feeding belt is arranged below the third feeding belt. The rotating direction of the fourth feeding belt is opposite to that of the third feeding belt. There is a horizontal cloth stacking gap between the third feeding belt and the fourth feeding belt. At one end of the horizontal cloth stacking gap, there is a second inserting plate and a horizontal driving mechanism linked to the second inserting plate.

[0020] It should be noted that the rotating directions of the first feeding belt and the second feeding belt are the same. This is because the middle part of the vest apron needs to move to the vertical cloth stacking gap for folding. Therefore, the second feeding belt needs to rotate in the same direction as the first feeding belt.

[0021] The above-mentioned fully automatic non-woven fabric vest apron machine can be further configured as follows: a fifth feeding belt is arranged above the first feeding belt. The rotating direction of the fifth feeding belt is opposite to that of the first feeding belt. The first feeding belt, the second feeding belt, the third feeding belt, the fourth feeding belt, and the fifth feeding belt are all linked with driving rollers respectively. The ends of each group of driving rollers are linked with sprockets. The sprockets are linked with each other through chains. A seventh servo motor is installed on the machine frame. The end of the seventh servo motor is linked with the chains through sprockets.

[0022] Adopting the above technical solution, the fifth feeding belt and the first feeding belt rotate in opposite directions to each other, applying a slight pressure to the apron before stacking to eliminate wrinkles.

[0023] The above-mentioned fully automatic non-woven fabric vest apron machine can be further configured as follows: the first inserting plate is fixedly connected with a linkage seat. The lifting driving mechanism includes a slide rail fixedly installed on the linkage seat. The slide rail is slidably matched with a slider. The slider is fixed on the machine frame. The linkage seat is hinged with a second swing arm. The end of the second swing arm away from the linkage seat is hinged on a cam. The cam is linked with an eighth servo motor. The horizontal driving mechanism has the same structure as the lifting driving mechanism.

[0024] With the above technical solution, the single-piece vest apron after cutting is output from the neck cutting integrated device and conveyed in the same direction by the first feeding belt and the second feeding belt until the middle of the single-piece vest apron corresponds to the entrance of the vertical cloth stacking gap. The lifting drive mechanism converts the rotary motion into a vertical reciprocating motion through transmission components such as a cam and a second swing arm, and drives the first plug board to press down, pushing the vest apron into the vertical cloth stacking gap to complete the first vertical skirt stacking action. Under the traction of gravity and the first feeding belt and the third feeding belt, the vest apron moves downward until the middle of the vertically folded vest apron corresponds to the horizontal cloth stacking gap between the third feeding belt and the fourth feeding belt. The horizontal drive mechanism (with the same structure as the lifting drive mechanism) pushes the second plug board to move horizontally, pushing the vertically stacked aprons into the horizontal cloth stacking gap. Under the reverse traction of the fourth feeding belt, the vest apron moves horizontally and is neatly stacked, completing the multi-directional cross stacking. After the vest apron passes through the cloth stacking device, it is cross-stacked vertically and horizontally, and the space utilization rate is increased by 40%, which is suitable for large-scale finished product packaging.

[0025] Advantages of the present invention: (1) The full-automatic non-woven fabric vest apron machine can produce a vest-style apron with more comprehensive protection, covering the chest, abdomen and back areas, and solving the problem that traditional aprons only protect the front. (2) Through modular devices such as double automatic feeding, bag mouth cutting and welding, pressing and traction, strap cutting, and neck cutting, the full-automatic production from the film cloth to the finished product is realized, with high production efficiency and meeting the large-scale demand for disposable non-woven fabric vest aprons, which are consumables.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 18The shown fully automatic non-woven fabric vest apron machine includes a frame, on which a double automatic feeding device a for transporting the upper layer of fabric and the lower layer of fabric, a bag mouth feeding and cutting device b for transporting the bag mouth fabric, cutting the bag mouth fabric into single pieces of bag mouth, and fixing the single pieces of bag mouth on the upper layer of fabric or the lower layer of fabric, a pressing and traction device c for laminating the upper layer of fabric and the lower layer of fabric vertically and welding the shoulders, a triangular folding device d for folding the composite fabric formed by laminating the upper layer of fabric and the lower layer of fabric with the bag mouth welded thereon, a strap cutting device e for cutting out the straps, a neckline cutting and separating device f for cutting out the neckline and cutting the continuous fabric into single-piece vests and aprons, and a fabric stacking device g arranged on one side of the neckline cutting and separating device f away from the strap cutting device e.

[0030] The double automatic feeding device a includes a material passing frame a1 and an upper fabric transporting mechanism and a lower fabric transporting mechanism respectively arranged at both ends of the material passing frame a1. The upper fabric transporting mechanism includes a first swing arm a2, a fabric unwinding roller a3, and a first cylinder a4. One end of the first swing arm a2 is hinged to the frame, and the other end is provided with a bayonet a5. The end of the fabric unwinding roller a3 is rotatably installed at the bayonet a5. One side of the body of the first cylinder a4 is hinged to the middle of the first swing arm a2, and the other side of the body of the first cylinder a4 is hinged to a support block a6. Both ends of the support block a6 are fixedly connected with support rods a7, and the support rods a7 are fixed to the first swing arm a2. The output end of the first cylinder a4 is hinged to a positioning block a9, and the positioning block a9 is fixed to the frame. A magnetic powder clutch a8 is installed on the first swing arm a2, and the output end of the magnetic powder clutch a8 is linked with the fabric unwinding roller a3 through a first transmission gear set a10. The upper fabric transporting mechanism and the lower fabric transporting mechanism have the same structure. The upper layer of fabric transported by the upper fabric transporting mechanism passes through the upper part of the material passing frame a1 and is transported forward, and the lower layer of fabric transported by the lower fabric transporting mechanism is transported forward from the lower part of the end of the material passing frame a1. Among them, the first transmission gear set a10 includes a driving gear linked with the magnetic powder clutch, a driven gear linked with the unwinding roller, and the driving gear is meshed and transmitted with the driven gear through an intermediate gear.

[0031] First, the upper and lower layer fabric are guided by the space of the material passing rack a1 in a layered manner (the upper layer passes through the top and the lower layer passes through the bottom), avoiding interference between the upper and lower layer fabric and saving space at the same time. Secondly, magnetic powder clutches a8 are equipped on both the upper and lower fabric feeding mechanisms, which can independently adjust the feeding speed and tension of each layer of fabric, ensuring that the double fabric are synchronously aligned in the complex transportation path and avoiding deviation or wrinkles. Among them, the first cylinder a4 pushes the first swing arm a2 to swing around the hinge point through telescopic movement, adjusting the position of the fabric feeding roller a3 and also controlling the tension of the fabric; further, when the fabric breaks or the feeding ends, the magnetic powder clutch a8 immediately cuts off the power supply, and the feeding roller stops rotating. At the same time, the first cylinder a4 pushes the swing arm to reset to the initial position, and through the bayonet a5, rapid roll change is realized. Moreover, the upper fabric feeding mechanism and the lower fabric feeding mechanism adopt exactly the same structure, with good interchangeability, facilitating rapid replacement and repair. Among them, the support rod a7 connects the first swing arm a2 and the support block a6 to form a stable triangular frame, enhancing the bending stiffness of the first swing arm a2 during dynamic swinging and preventing deformation of the first swing arm a2 caused by fabric tension or cylinder thrust. The thrust of the first cylinder a4 is transmitted to the first swing arm a2 through the support rod a7, reducing the local stress concentration at the hinge point of the first swing arm a2 and prolonging the service life of the first swing arm a2.

The end of the bag mouth cutting cooperation roller b3 is linked with a first servo motor b7 through a first chain drive assembly b6, and the end of the upper cutting roller b2 is linked with the end of the bag mouth cutting cooperation roller b3 through a second transmission gear set b8. Among them, the second transmission gear set b8 includes a driving gear linked with the upper cutting roller b2 and a driven gear linked with the cutting cooperation roller. The driving gear and the driven gear are meshed and driven; the first chain drive assembly b6 includes a driven sprocket linked with the end of the cutting cooperation roller and a driving sprocket linked with the output end of the servo motor. The driven sprocket and the driving sprocket are driven by a chain; the first servo motor b7 drives the cutting cooperation roller and the second transmission gear set b8 to work synchronously through the first chain drive assembly b6, and the second transmission gear set b8 thus drives the upper cutting roller b2 to work.

The second chain transmission assembly b14 includes a driving sprocket linked with the driving roller b11 and a driven sprocket linked with the output end of the second servo motor b15, and the driven sprocket and the driving sprocket are driven by a chain. The second servo motor b15 drives the driving roller b11 to rotate through the second chain transmission assembly b14, so that the driving belt b9 works.

Among them, the fourth transmission gear set b18 includes a driven gear linked with the bag mouth welding roller b16 and a driving gear hinged on the machine frame, and the driving gear meshes with the driven gear for transmission. The third chain transmission assembly b19 includes a driven sprocket linked with the driving gear and a driving sprocket linked with the output end of the third servo motor b20, and the driven sprocket and the driving sprocket are driven by a chain. The third servo motor b20 drives the driving gear to rotate through the third chain transmission assembly b19, and the driven gear rotates following the driving gear, so as to drive the bag mouth welding roller b16 to rotate.

[0035] The bag mouth fabric unwinding roller b1 transports the bag mouth fabric in an orderly manner. The bag mouth fabric first passes through the bag mouth cutting roller mechanism. The first servo motor b7 drives the bag mouth cutting and mating roller b3 to rotate through the first chain drive assembly b6. The bag mouth mating roller drives the upper cutting roller b2 through the second transmission gear set b8 to achieve synchronous reverse rotation of the two rollers and complete the periodic cutting action. The bag mouth cutting edge b4 on the surface of the upper cutting roller b2 is used for cutting, and the avoidance plane b5 on its surface rotates to correspond to the fabric after cutting to avoid secondary contact with the bag mouth fabric. The single-piece bag mouth then passes through the transfer and flattening mechanism. The driving belt b9 drives the driving roller b11 to rotate by the second servo motor b15. The driven belt b10 is linked with the driving roller b11 through the third transmission gear set b13 to achieve synchronous movement of multiple groups of belts. The cut single-piece bag mouth is clamped between the belts and smoothly transported to the next station by friction. The multiple groups of belts are arranged at intervals to form a "segmented flattening" effect to eliminate the wrinkles generated by cutting or transportation of the bag mouth. The first guiding and traction roller group b21 is used to traction the single-piece bag mouth and the lower-layer fabric, press the single-piece bag mouth onto the lower-layer fabric, and synchronously traction the two to the bag mouth welding mechanism. The third servo motor b20 drives the welding roller to rotate through the third chain drive assembly b19 and the fourth transmission gear set b18 to ensure that the welding speed is synchronized with the bag mouth transportation speed to avoid misalignment. The bag mouth welding roller b16 is provided with a bag mouth welding edge b22 on its surface for positioning the welding paths on both sides and the bottom edge of the bag mouth; the ultrasonic welding head vibrates at high frequency to generate heat energy and fuses the bag mouth and the lower-layer fabric through pressure.

[0036] The pressing and traction device c includes a shoulder welding roller mechanism and a second guiding and traction roller group c1. The second guiding and traction roller group c1 is distributed between the shoulder welding roller mechanism and the bag mouth welding roller mechanism, and the second guiding and traction roller group c1 is used to traction the upper-layer fabric and the lower-layer fabric with the bag mouth welded thereon into the shoulder welding roller mechanism; the shoulder welding roller mechanism includes a shoulder welding roller c2 and a shoulder ultrasonic welding head c3 which are arranged oppositely up and down. The end of the shoulder welding roller c2 is linked with a fourth chain drive assembly c5 through a fifth transmission gear set c4. The fourth chain drive assembly c5 is linked with a fourth servo motor c6. The outer peripheral surface of the shoulder welding roller c2 is provided with a shoulder welding edge c7 for welding the shoulder.

[0037] The second guiding and traction roller group c1 is used to traction the upper layer of the film cloth and the lower layer of the film cloth with the bag mouth welded, and press the upper layer of the film cloth and the lower layer of the film cloth with the bag mouth welded together up and down to form a composite film cloth, and synchronously traction it into the shoulder welding roller mechanism. The fourth servo motor c6 drives the fifth transmission gear group c4 through the fourth chain transmission component c5, drives the shoulder welding roller c2 to rotate at a constant speed, ensures that the welding speed is synchronized with the traction speed, and avoids welding misalignment. When the composite film cloth with the bag mouth welded passes through the gap between the shoulder welding roller c2 and the shoulder ultrasonic welding head c3, the shoulder welding edge c7 defines the welding area, and the ultrasonic energy penetrates the film cloth to achieve rapid welding. Among them, the fifth transmission gear group c4 includes a driven gear linked to the shoulder welding roller c2 and a driving gear hinged on the frame, and the driving gear meshes with the driven gear for transmission; the fourth chain transmission component c5 includes a driven sprocket linked to the driving gear and a driving sprocket linked to the output end of the fourth servo motor c6, and the driven sprocket and the driving sprocket are driven by a chain; the fourth servo motor c6 drives the driving gear to rotate through the fourth chain transmission component c5, and the driven gear follows the driving gear to rotate, thereby driving the shoulder welding roller c2 to rotate.

[0038] Among them, the first guiding and traction roller group b21 and the second guiding and traction roller group c1 both include an upper traction roller and a lower traction roller arranged oppositely up and down. A driven gear is linked to the end of the upper traction roller, a driving gear is linked to the end of the lower traction roller, the driven gear meshes with the driving gear for transmission, and a driven sprocket is also linked to the end of the lower traction roller. The driven sprocket is linked to a driving sprocket through a chain, and the driving sprocket is linked to the output end of the servo motor. The servo motor drives the lower traction roller to rotate through the driving sprocket, the chain and the driven sprocket, and the upper traction roller rotates synchronously with the lower traction roller to achieve traction.

[0039] The triangular folding device d includes a triangular plate d1 in the shape of an isosceles triangle. Above the top angle of the triangular plate d1, two groups of folding and pressing rollers d2 are arranged relatively. At the bottom of the triangular plate d1, a cloth stacking feeding roller d3 is arranged, and the folding and pressing rollers d2 and the cloth stacking feeding roller d3 are perpendicular to each other in different planes. The composite film cloth (with the pocket welded and the shoulder welded) passes through the cloth stacking feeding roller d3 and the triangular plate d1 in sequence and then enters between the two groups of folding and pressing rollers d2 to complete folding.

[0040] The strap cutting device e includes a strap cutting roller e1 and a strap cutting cooperating roller e2 which are arranged oppositely up and down. A strap cutting edge e6 for cutting the strap is provided on the outer peripheral surface of the strap cutting roller e1. The end of the strap cutting cooperating roller e2 is linked with a fifth servo motor e3 through a fifth chain drive assembly e4, and the end of the strap cutting roller e1 is linked with the end of the strap cutting cooperating roller e2 through a sixth transmission gear set e5. The folded composite film cloth is laid flat through the gap between the strap cutting roller e1 and the strap cutting cooperating roller e2 from the upstream process (the triangular folding device d). The fifth servo motor e3 drives the strap cutting cooperating roller e2 to rotate through the fifth chain drive assembly e4, and the cutting cooperating roller drives the strap cutting roller e1 through the sixth transmission gear set e5, so that the two rollers rotate in opposite directions to cut the straps on the front and back sides. Among them, the fifth chain drive assembly e4 includes a driven sprocket linked with the strap cutting cooperating roller e2 and a driving sprocket linked with the output end of the fifth servo motor e3, and the driven sprocket and the driving sprocket are driven by a chain; the sixth transmission gear set e5 includes a driving gear linked with the strap cutting cooperating roller e2 and a driven gear linked with the strap cutting roller e1, and the driving gear and the driven gear are engaged in transmission; the fifth servo motor e3 drives the strap cutting cooperating roller e2 to rotate through the fifth chain drive assembly e4, and the strap cutting cooperating roller e2 drives the strap cutting roller e1 to rotate synchronously through the sixth transmission gear set e5.

[0041] The neckline cutting and blanking integrated device f includes a neckline cutting roller f1 and a neckline cutting cooperating roller f2 which are arranged oppositely up and down. A neckline cutting edge f6 for cutting the neckline and a blanking edge f7 for cutting the continuous composite film cloth with the neckline cut into single-piece waistcoat aprons are provided on the outer peripheral surface of the neckline cutting roller f1. The end of the neckline cutting cooperating roller f2 is linked with a sixth servo motor through a sixth chain drive assembly f3, and the end of the neckline cutting roller f1 is linked with the end of the neckline cutting cooperating roller f2 through a seventh transmission gear set f4.

Among them, the sixth chain drive assembly f3 includes a driven sprocket linked with the neckline cutting cooperating roller f2 and a driving sprocket linked with the output end of the sixth servo motor, and the driven sprocket and the driving sprocket are driven by a chain; the seventh transmission gear set f4 includes a driving gear linked with the neckline cutting cooperating roller f2 and a driven gear linked with the neckline cutting roller f1, and the driving gear and the driven gear are engaged in transmission; the sixth servo motor drives the neckline cutting cooperating roller f2 to rotate through the sixth chain drive assembly f3, and the neckline cutting cooperating roller f2 drives the neckline cutting roller f1 to rotate synchronously through the seventh transmission gear set f4.

[0042] The continuous composite film fabric that has completed the band cutting and folding enters the gap between the neckline cutting roller f1 and the mating roller. The sixth servo motor drives the rotation of the neckline cutting mating roller f2 through the sixth chain drive assembly f3. The neckline cutting mating roller f2 drives the neckline cutting roller f1 through the seventh transmission gear set f4 to ensure that the two rollers rotate in opposite directions. Using the neckline cutting edge f6 and the cutting edge f7, continuous cutting and severance are achieved. The blower assembly adsorbs the neckline waste through the waste suction pipe f5 and transports it to the waste collection device.

[0043] The cloth stacking device g includes a first feeding belt g1 and a second feeding belt g2 that are arranged opposite to each other left and right. The rotation directions of the first feeding belt g1 and the second feeding belt g2 are the same. One end of the first feeding belt g1 is connected to the discharge side of the neckline cutting and severing integrated device f. There is a vertical cloth stacking gap g3 between the other end of the first feeding belt g1 and the second feeding belt g2. Above the vertical cloth stacking gap g3, there is a first plug board g4 and a lifting drive mechanism linked to the first plug board g4. Below the second feeding belt g2, there is a third feeding belt g5. The rotation direction of the third feeding belt g5 is opposite to that of the second feeding belt g2. The vertical cloth stacking gap g3 extends between the first feeding belt g1 and the third feeding belt g5. Below the third feeding belt g5, there is a fourth feeding belt g6. The rotation direction of the fourth feeding belt g6 is opposite to that of the third feeding belt g5. There is a horizontal cloth stacking gap g7 between the third feeding belt g5 and the fourth feeding belt g6. At one end of the horizontal cloth stacking gap g7, there is a second plug board g8 and a horizontal drive mechanism g9 linked to the second plug board g8. It should be noted that the rotation directions of the first feeding belt g1 and the second feeding belt g2 are the same because the middle part of the vest apron needs to move to the vertical cloth stacking gap g3 for the folding action to be carried out. Therefore, the second feeding belt g2 needs to maintain the same rotation direction as the first feeding belt g1.

[0044] Above the first feeding belt g1, there is a fifth feeding belt g10. The rotation direction of the fifth feeding belt g10 is opposite to that of the first feeding belt g1. The first feeding belt g1, the second feeding belt g2, the third feeding belt g5, the fourth feeding belt g6, and the fifth feeding belt g10 are all respectively linked to a drive roller g12. The ends of each group of drive rollers g12 are linked to a sprocket. The sprockets are linked to each other through a chain. A seventh servo motor g11 is installed on the frame. The end of the seventh servo motor g11 is linked to the chain through a sprocket. The fifth feeding belt g10 and the first feeding belt g1 rotate in opposite directions to apply a slight pressure to the apron before stacking to eliminate wrinkles.

[0045] The first plug board g4 is fixedly connected with a linkage seat g13. The lifting drive mechanism includes a slide rail g14 fixedly installed on the linkage seat g13. A slider g15 is slidably engaged with the slide rail g14. The slider g15 is fixed to the frame. The linkage seat g13 is hinged with a second swing arm g16. The end of the second swing arm g16 far from the linkage seat g13 is hinged to a cam g17. The cam g17 is linked with an eighth servo motor g18. The transverse drive mechanism g9 has the same structure as the lifting drive mechanism.

[0046] The cut single-piece vest apron is output from the neck cut-off integrated device f and is conveyed in the same direction by the first conveyor belt g1 and the second conveyor belt g2 until the middle of the single-piece vest apron corresponds to the entrance of the vertical cloth stacking gap g3. The lifting drive mechanism converts the rotational motion into a vertical reciprocating motion through transmission components such as the cam g17 and the second swing arm g16, driving the first plug board g4 to press down and push the vest apron into the vertical cloth stacking gap g3 to complete the first vertical skirt stacking action. Under the traction of gravity and the first conveyor belt g1 and the third conveyor belt g5, the vest apron moves downward until the middle of the vertically folded vest apron corresponds to the horizontal cloth stacking gap g7 between the third conveyor belt g5 and the fourth conveyor belt g6. The transverse drive mechanism g9 (with the same structure as the lifting drive mechanism) pushes the second plug board g8 to move horizontally, pushing the vertically stacked aprons into the horizontal cloth stacking gap g7. The vest apron moves horizontally and is neatly stacked under the reverse traction of the fourth conveyor belt g6 to complete the multi-directional cross stacking. After the vest apron passes through the cloth stacking device g, it is stacked vertically and horizontally, and the space utilization rate is increased by 40%, which is suitable for large-batch finished product packaging.

[0047] The working principle of this embodiment is as follows: The double automatic feeding device a transports the upper film cloth and the lower film cloth in an orderly manner, and the upper film cloth and the lower film cloth are distributed vertically. The bag mouth feeding and cutting device b is distributed between the upper film cloth and the lower film cloth, saving space.

[0048] The bag mouth feeding and cutting device b transports the continuous bag mouth film cloth in an orderly manner and cuts it into single pieces of bag mouths through the bag mouth cutting roller mechanism. The transfer and flattening mechanism synchronously pulls the single pieces of bag mouths and the lower film cloth into the bag mouth welding roller mechanism. The bag mouth welding roller mechanism welds the single pieces of bag mouths to the lower film cloth, and the two side edges and the bottom edge of the bag mouth remain fixedly connected to the lower film cloth.

[0049] The second guiding and traction roller group c1 synchronously pulls the upper film cloth and the lower film cloth with the bag mouth welded to the shoulder welding roller mechanism to complete the welding of the shoulders. It should be noted that the bag mouth is located between the upper film cloth and the lower film cloth and is not exposed on the surface of the lower film cloth.

[0050] Immediately afterwards, the triangular folding device d folds the composite film cloth (the upper film cloth and the lower film cloth with the shoulders and the bag mouths welded).

[0051] The strap cutting device e cuts out the straps on both sides of the front and back bodies of the vest apron, and the number of straps is four groups.

[0052] The neckline cutting and forming device f cuts out the neckline and cuts the continuous composite film cloth (the shoulders and the bag mouths are both hot welded, and the upper and lower film cloths for cutting out the straps) into individual vest aprons. This step has completed the processing of the non-woven fabric vest apron, and the vest apron has been formed.

[0053] Finally, the cloth stacking device g folds the vest apron to form a smaller block for convenient packaging.

[0054] It should be noted that the vest apron produced by this embodiment is in the reverse state. When in use, the vest apron needs to be turned over until the pocket is exposed on the outer surface of the vest apron, which is the appropriate use state. After turning over, the fusion line on the shoulder of the vest apron is shielded inside the vest apron, improving the aesthetics.

[0055] In this embodiment, a vest-style apron with detachable connection of the front and back bodies is formed by pressing the upper and lower layer film cloths, covering the chest, abdomen and back areas, solving the defect that traditional aprons only protect the front, and is suitable for scenarios such as medical treatment and cleaning that require protection against back contamination. Double automatic feeding, cutting, hot welding and other devices are integrated and linked to complete the whole process production of the apron from raw materials to finished products, with the efficiency increased by dozens of times compared with manual work, meeting the large-scale demand for disposable consumables.
