Description

Technical Field

[0001] The utility model particularly relates to a bib machine. Background Art

[0002] Existing disposable bibs generally include a skirt, a lanyard for hanging on the neck, and a left strap and a right strap for tying the skirt around the waist to fix the skirt.

[0003] The Chinese invention patent application document with the publication number of "CN117426592A" discloses a bib manufacturing machine, which mainly includes a feeding mechanism, a pre-stretching mechanism, a skirt cutting mechanism, a sling connecting mechanism, a left strap connecting mechanism, a right strap connecting mechanism and a cutting and outputting mechanism. The feeding mechanism outputs the fabric, and the output fabric is cut into the shape of the skirt in the skirt cutting mechanism through the pre-stretching mechanism. The shoulder of the skirt is still connected and not disconnected. The skirt enters the sling connecting mechanism to connect the sling at the neckline. The skirt connected with the sling enters the left strap connecting mechanism to connect the left strap. The skirt connected with the sling and the left strap enters the right strap connecting mechanism to connect the right strap on the side of the skirt opposite to the left strap. The skirt that has completed the connection of the sling, the left strap and the right strap enters the cutting and outputting mechanism to cut the shoulder connection of the skirt and output the device.

[0004] First, paragraph 0010 of the specification of the application document discloses that "during the process of cutting the cloth, the second traction device and the third traction device suspend traction." From this, it can be seen that the cloth will stop being transported in the process of cutting into the initial bib shape, that is, it needs to be shut down for processing. The shutdown processing here means that the material stops being transported forward until the cutting is completed, which greatly affects work efficiency.

[0005] Secondly, paragraph 0016 of the specification of the application document discloses that "the fourth and fifth traction devices suspend traction when the hanging strap, left strap and right strap are connected respectively." From this, it can be seen that the bib manufacturing machine needs to be shut down when hot-welding the hanging strap, left strap and right strap respectively. The shutdown here means that the material is suspended from being transported forward until the hot-welding of the left strap or the right strap is completed, which further reduces the work efficiency. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a bib machine in view of the deficiencies of the above-mentioned prior art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bib machine, including a frame, the frame is sequentially provided with a feeding mechanism, a pre-stretching mechanism, a skirt cutting mechanism, a hanging strap connecting mechanism, a left strap connecting mechanism, a right strap connecting mechanism and a cutting output mechanism, characterized in that: the skirt cutting mechanism includes a pressure roller and a skirt knife roller relatively distributed up and down, the outer peripheral surface of the skirt knife roller is provided with a cutting blade protruding toward the outside, the two ends of the skirt knife roller are installed on the cutting mounting frame through bearings, the two ends of the pressure roller are also installed on the cutting mounting frame through bearings, one end of the skirt knife roller is linked to a driving component, and the driving component can drive the skirt knife roller to rotate so that the cutting blade cuts the cloth.

[0008] The above technical solution is adopted to improve the skirt cutting mechanism, the driving component drives the skirt blade roller to rotate, the pressure roller rotates under the driving of the cloth transportation, and the pressure roller and the skirt blade roller cooperate with each other, and the cutting blade can cut out the outer contour of the skirt. At this time, only the outer shape is cut out without segmenting each bib, and the shoulder of the bib is connected to the bottom of the adjacent bib. It can be clearly seen from the working process that the cloth does not need to be suspended during the cutting process, which improves the production efficiency compared with the prior art. Among them, the pre-pulling mechanism pulls out the cloth in the feeding mechanism, and the cloth first enters the skirt cutting mechanism for cutting, and the bib shape is processed, and then enters the hanging strap connection mechanism for hot welding of the hanging strap; then it enters the left strap connection mechanism and the right strap connection mechanism at the same time to perform hot welding of the left and right straps, and finally the cutting output mechanism divides the cloth into individual bibs and outputs them. Among them, the driving component can adopt the sprocket-motor driving mode to realize the control of the rotation of the skirt blade roller.

[0009] The above-mentioned bib machine can be further configured as follows: the pressing roller is distributed above the skirt knife roller, the cutting mounting frame is connected to a support beam distributed on the pressing roller, a group of bearing supports are respectively provided at both ends of the support beam, needle bearings are respectively hinged at both ends of the bearing supports, and the lower end of the needle bearing is in rolling contact with the pressing roller; the end of the skirt knife roller is linked to a first slider through a bearing, the end of the pressure roller is linked to a second slider through a bearing, the end of the support beam is connected to a third slider, and first slide grooves are respectively provided on both sides of the cutting mounting frame, and the first slider, the second slider, and the third slider are respectively connected to the cutting mounting frame through the first slide grooves.

[0010] The above technical solution is adopted to set needle bearings at both ends of the pressure roller to give the pressure roller a downward pressure, balance the pressure, and make cutting more accurate. Among them, the support beam and bearing support are designed to facilitate the installation of the needle bearing; the first slide, the first slider, the second slider, and the third slider are designed to facilitate the adjustment of the position of the skirt knife roller, the pressure roller, and the needle bearing according to the actual situation, ensuring more accurate cutting accuracy.

[0012] With the above technical solution, the fourth motor drives the screw to rotate, and the nut slides back and forth along the axis of the screw, thereby driving the sliding frame to slide back and forth along the axis of the screw. During the reciprocating sliding of the sliding frame, the hanging belt welding device, the hanging belt coiling rack, the hanging belt steering device, the hanging belt pulling device, and the hanging belt cutting device all slide back and forth with the sliding frame. During the hot welding of the hanging belt, the cloth does not need to be stopped for transportation. After each hot welding is completed, the sliding frame returns to the initial position under the control of the fourth motor to perform the next hanging belt hot welding. Compared with the prior art, not only does cutting not need to be stopped, but also the hanging belt hot welding does not need to be stopped for processing, which further improves production efficiency.

[0013] The above-mentioned bib machine can be further configured as follows: the sliding frame is also equipped with a first tensioning adjustment component distributed between the hanging belt coiling rack and the hanging belt cutting device, the first tensioning adjustment component includes a first adjustment plate, one end of the first adjustment plate is hinged to the sliding frame, and the first adjustment plate is provided with a plurality of groups of first pull-down pulleys, and the plurality of groups of first pull-down pulleys are distributed in sequence along the axis direction of the first adjustment plate; the first tensioning adjustment component also includes a plurality of groups of first upper pulleys distributed above the first adjustment plate, and the plurality of groups of first upper pulleys are respectively hinged to the sliding frame, and the first adjustment plate is provided with weight reduction holes.

[0014] With the above technical solution, the lanyard is alternately wound around the first upper pulley and the first lower pulley in sequence. Under the action of the gravity of the first adjustment plate and the tension of the lanyard itself, the first adjustment plate will rotate around the hinge with the sliding frame to adapt to the tension change of the lanyard and adjust the tension. Further, by setting the weight-reducing hole, it is avoided that the gravity of the first adjustment plate is too large, causing the lanyard to be overstretched.

[0015] The above-mentioned bib machine can be further configured as follows: the left strap connection mechanism and the right strap connection mechanism have the same structure and are symmetrically distributed; the right strap connection mechanism includes a drawstring plate fixed on the frame, and a drawstring coil rack installed above the drawstring plate; a first clamping member, a strap cutting member, a second clamping member, and a welding member are sequentially arranged below the drawstring plate along the direction of fabric transportation; a second tensioning adjustment member is arranged above the drawstring plate; the end of the first clamping member is linked to a fourth cylinder and can reciprocate along the direction of fabric transportation under the drive of the fourth cylinder; the upper part of the second clamping member is linked to a transmission seat through a bearing; the transmission seat A first motor is installed on the side, and the output end of the first motor is linked to a first pulley, the first pulley is linked to a first transmission belt, the second clamping piece is linked to the first transmission belt by setting a second pulley, the transmission seat is fixedly connected to a slide seat, the slide seat is linked to the second transmission belt, the pulling plate is installed with a second guide rail arranged parallel to the second transmission belt, the slide seat is slidably connected to the second guide rail, the two ends of the second transmission belt are respectively linked to third pulleys, the third pulley is linked to the second motor, and the second motor drives the first clamping piece to move between the strap cutting component and the welding component through the second transmission belt.

[0016] By adopting the above technical solution, the left strap connection mechanism and the right strap connection mechanism are designed as symmetrical structures, so that the cloth machine has good interchangeability and is easy to maintain; further, under the action of the second transmission belt, the second guide rail, and the slide seat, the second clamping member can reciprocate between the strap cutting component and the welding component. When the left strap and the right strap are hot-welded, the cloth does not need to be suspended for transportation. Compared with the prior art, not only does the cutting and hanging strap hot-welding not need to be stopped, but also the left strap and the right strap do not need to be stopped for processing. Therefore, the cloth does not need to be suspended for transportation during the entire process of cloth production, which greatly improves the production efficiency. Further, by setting the first motor, the first pulley, the second pulley, and the first transmission belt, the rotation of the second clamping member can be controlled to realize the steering of the right strap and hot-weld it on the cloth in the correct direction. Compared with the prior art, the rotation of the second clamping member has a fast response speed, and will not be stuck, the production efficiency is higher, and the rotation angle can also be adjusted according to actual conditions. Furthermore, the left strap connection mechanism and the right strap connection mechanism designed in the present application abandon the "lifting" components in the prior art. The second clamping member only needs to move back and forth along the fabric transport direction and make turns without lifting up and down. This also reduces the risk of damage to the second clamping member and extends its service life.

[0017] The above-mentioned bib machine can be further configured as follows: the frame is rotatably connected to a pull-down roller and a lifting roller, the pull-down roller and the lifting roller are both arranged perpendicular to the fabric transportation mode, the pull-down roller is distributed below the draw belt plate and there is a gap between the two, and the lifting roller is distributed between the pull-down roller and the welding component.

[0018] By adopting the above technical solution, when the cloth enters the left strap connecting mechanism and the right strap connecting mechanism, it will be pulled down by the pull-down roller until it is away from the first clamping member, the strap cutting member and the second clamping member. This can avoid the first clamping member, the strap cutting member and the second clamping member from interfering with the cloth during operation. When the cloth passes through the pull-down roller and enters the lifting roller, the lifting roller lifts the cloth to the same height as the welding member, which is convenient for hot welding of the cloth with the left strap and the right strap. This is also the reason why the second clamping member does not need to be raised or lowered.

[0019] The above-mentioned bib machine can be further configured as follows: the second tensioning adjustment component includes a second adjustment plate, one end of the second adjustment plate is hinged to the drawstring plate, a plurality of groups of second lower pulleys are provided on the second adjustment plate, and the plurality of groups of second lower pulleys are distributed in sequence along the axial direction of the second adjustment plate; the second tensioning adjustment component also includes a plurality of groups of second upper pulleys distributed above the second adjustment plate, the plurality of groups of second upper pulleys are respectively hinged to the drawstring plate, and the second adjustment plate is also provided with weight reduction holes.

[0020] With the above technical solution, the right strap is alternately wound around the second upper pulley and the second lower pulley in sequence. Under the gravity of the second adjustment plate and the tension of the right strap itself, the second adjustment plate will rotate around the hinge with the pull plate to adapt to the tension change of the right strap and adjust the tension. Further, by providing a weight-reducing hole, it is prevented that the gravity of the second adjustment plate is too large, causing excessive stretching of the right strap.

[0021] The above-mentioned bib machine can be further configured as follows: a strap pressing component distributed between the coil rack and the clamping station is installed on the strap drawing plate, the strap pressing component includes a strap pressing plate, one end of the strap pressing plate is provided with a strap inlet, the middle is provided with a strap pressing channel, and the other end is provided with a strap outlet, the two ends of the strap pressing channel are respectively conductively connected with the strap inlet and the strap outlet, the strap pressing plate is connected with a first sheet metal, the side edge of the first sheet metal is connected to the strap drawing plate by screws, the strap outlet end of the strap pressing plate is provided with an upper pressing wheel and a lower pressing wheel which are relatively distributed up and down, the end of the lower pressing wheel is hinged on the strap drawing plate, the middle part of the upper pressing wheel is provided with a rotating shaft, the two ends of the rotating shaft are respectively linked with connecting blocks, a supporting block is provided between the two groups of connecting blocks, and the supporting block is linked with a first cylinder.

[0022] By adopting the above technical solution, a strap pressing component is provided to limit the right strap and prevent the right strap from being pulled back. Compared with the prior art, the right strap does not need to be folded in half, which reduces the number of steps. Among them, the right strap enters from the strap inlet, passes through the strap pressing channel, and finally passes through the strap outlet, which compacts the right strap and prevents the right strap from being pulled back. Furthermore, a first sheet metal is provided to facilitate the installation of the strap pressing plate. An upper pressing wheel and a lower pressing wheel are provided to be relatively distributed up and down to further compact the right strap and improve the transportation stability of the right strap. A first cylinder, a support block, a connecting block, and a rotating shaft are further provided to facilitate the adjustment of the position of the upper pressing wheel according to actual conditions, so as to better cooperate with the lower pressing wheel to compact the right strap.

[0023] The above-mentioned bib machine can be further configured as follows: the welding component includes an ultrasonic ironing head and a pressing block distributed at the welding station, the ultrasonic ironing head is distributed at the lower end of the pressing block, one end of the pressing block is provided with a plurality of groups of pressing teeth, and the other end is linked to a melting gear shaft, the middle part of the melting gear shaft is hinged to the drawstring plate through a bearing, one end of the melting gear shaft is provided with a strip groove, the middle part of the strip groove is provided with a screw hole, the other end of the pressing block is inserted into the strip groove, and the other end of the pressing block is also provided with a strip hole corresponding to the screw hole, and the other end of the melting gear shaft is linked to a third motor through a pulley assembly.

[0024] With the above technical solution, the third motor controls the rotation of the melting gear shaft through the pulley assembly, and the melting gear shaft drives the pressing block to rotate. Whenever the pressing block rotates to the bottom, the pressing gear heat-welds the right strap to the bib. Among them, the strip groove, screw hole, and strip hole are designed to adjust the relative position of the pressing block and the melting gear shaft according to actual conditions, so that the pressing block can accurately heat-weld the right strap and the fabric.

[0025] The above-mentioned bib machine can be further configured as follows: the strap cutting component includes a shears and a shearing fitting component, the shears are distributed between the shearing fitting component and the second clamping member, the shearing fitting component includes a mounting plate fixed at one end on the draw strap plate, a second cylinder is connected above the mounting plate, the output end of the second cylinder is linked to a pressure plate, a shearing fitting block corresponding to the pressure plate is connected below the mounting plate, a through hole is penetrated through the middle of the mounting plate, the shears include an upper scissor blade, a lower scissor blade, and a third cylinder, the same end of the upper scissor blade and the lower scissor blade are coaxially hinged, the end of the upper scissor blade is linked to an upper connecting rod, the end of the lower scissor blade is linked to a lower connecting rod, the output end of the third cylinder is hinged to the end of the upper connecting rod and the end of the lower connecting rod at the same time, and the body of the third cylinder is connected to a second sheet metal.

[0026] By adopting the above technical solution, when the right strap is cut, the second cylinder pushes the pressure plate to press down one end of the right strap. Since one end of the right strap has been hot-welded to the bib, both ends of the right strap are limited. When the shears cut the right strap, the length of the cut right strap can be accurately controlled. The working principle of the shears is as follows: when the output end of the third cylinder is extended, the ends of the upper connecting rod and the lower connecting rod away from the third cylinder are separated from each other, and the upper scissor blades and the lower scissor blades are in an open state. When the output end of the third cylinder is retracted, the ends of the upper connecting rod and the lower connecting rod away from the third cylinder are close to each other, and the upper scissor blades and the lower scissor blades are in a gathered state. This process realizes the shearing of the right strap. Further designing the second sheet metal is conducive to the installation of the third cylinder.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] like Figures 1 to 4The bib machine shown in the figure comprises a frame, on which a feeding mechanism a, a pre-drawing mechanism b, a skirt cutting mechanism c, a strap connection mechanism d, a left strap connection mechanism e, a right strap connection mechanism f and a cutting and outputting mechanism g are sequentially arranged. The pre-drawing mechanism b pulls the fabric out of the feeding mechanism a, and the fabric first enters the skirt cutting mechanism c for cutting to form a bib shape, and then enters the strap connection mechanism d for hot welding of the strap; then simultaneously enters the left strap connection mechanism e and the right strap connection mechanism f for hot welding of the left and right straps, and finally the cutting and outputting mechanism g divides the fabric into individual bibs and outputs them.

[0043] The skirt cutting mechanism c comprises a pressure roller c1 and a skirt blade roller c2 which are relatively distributed up and down. The outer peripheral surface of the skirt blade roller c2 is provided with a cutting blade c3 protruding outward. Both ends of the skirt blade roller c2 are mounted on the cutting mounting frame c5 through bearings. Both ends of the pressure roller c1 are also mounted on the cutting mounting frame c5 through bearings. One end of the skirt blade roller c2 is linked with a driving component, which can drive the skirt blade roller c2 to rotate so that the cutting blade c3 cuts the fabric. Among them, the driving component adopts a sprocket-motor driving mode. The skirt blade roller c2 is linked with the sprocket. The motor is driven through the chain and sprocket, that is, the rotation of the skirt blade roller c2 can be controlled. Among them, the cutting blade c3 mainly includes a collar fan-shaped blade line c10 located in the middle of the outer peripheral surface of the skirt knife roller c2, and outer contour blade lines c11 that are adapted to the two sides of the bib are symmetrically arranged on both sides of the collar fan-shaped blade line c10. It should be noted that the collar fan-shaped blade line c10 is not connected to the outer contour blade lines c11 on both sides, so as to ensure that the fabric after being cut by the skirt cutting mechanism c will form "the shoulder of the bib is connected to the bottom of the adjacent bib".

[0044] The pressure roller c1 is distributed above the skirt blade roller c2, and the cutting mounting frame c5 is connected to the support beam c12 distributed on the pressure roller c1. A group of bearing supports c13 are respectively provided at both ends of the support beam c12. Needle bearings c6 are respectively hinged at both ends of the bearing supports c13. The lower end of the needle bearing c6 is in rolling contact with the pressure roller c1. Needle bearings c6 are provided at both ends of the pressure roller c1 to give a downward pressure to the pressure roller c1, balance the pressure, and make the cutting more accurate. The design of the support beam c12 and the bearing support c13 facilitates the installation of the needle bearing c6. The end of the skirt blade roller c2 is linked to the first slider c9 through the bearing, and the end of the pressure roller c1 is linked to the second slider c8 through the bearing. The end of the support beam c12 is connected to the third slider c7. The first slide grooves c4 are respectively provided on both sides of the cutting mounting frame c5. The first slider c9, the second slider c8, and the third slider c7 are respectively connected to the cutting mounting frame c5 through the first slide grooves c4. The first slide groove c4, the first slider c9, the second slider c8 and the third slider c7 are designed to facilitate the adjustment of the positions of the skirt knife roller c2, the pressure roller c1 and the needle bearing c6 according to actual conditions, thereby ensuring more precise cutting accuracy.

[0045] The working principle of the skirt cutting mechanism c is as follows: the driving assembly drives the skirt blade roller c2 to rotate, the pressure roller c1 rotates under the driving of the cloth transportation, and the pressure roller c1 cooperates with the skirt blade roller c2, and the cutting blade c3 can cut the outer contour of the skirt. At this time, only the outer shape is cut without segmenting each bib, and the shoulder of the bib is connected to the bottom of the adjacent bib. It can be clearly seen from the working process that the cloth does not need to be stopped during the cutting process, which improves the production efficiency compared with the existing technology.

[0046] The strap connection mechanism d comprises a sliding frame d1, a fourth slider d2 is linked to the bottom of the sliding frame d1, the fourth slider d2 is slidably connected to the first guide rail d3, the first guide rail d3 is arranged parallel to the cloth transport direction and the first guide rail d3 is fixed to the frame d4, a nut d5 is connected to the bottom of the sliding frame d1, the nut d5 is threadedly connected to the screw rod d6, both ends of the screw rod d6 are hinged to the frame d4 through bearings, and one end of the screw rod d6 is linked to the fourth motor d8. The fourth motor d8 drives the screw rod d6 to rotate, and the nut d5 slides back and forth along the axis direction of the screw rod d6, thereby driving the sliding frame d1 to slide back and forth along the axis direction of the screw rod d6.

[0047] A strap welding device d9 and a strap coiling rack d10 are installed on the sliding rack d1. A strap steering device d11 is provided on one side of the strap welding device d9 for twisting the two ends of the cut strap to the strap welding device d9. A strap pulling device d12 is provided between the strap steering device d11 and the strap welding device d9 for pulling the strap on the strap coiling rack d10 to the strap steering device d11. A strap cutting device d13 is provided between the strap pulling device d12 and the strap coiling rack d10.

[0048] The strap pulling device d12 includes a strap clamping member d14 and a pulley assembly d15. The pulley assembly d15 controls the left and right lateral movement of the strap clamping member d14 to achieve the traction of the strap.

[0049] Among them, the hanging belt steering device d11 mainly includes a turning shaft d16 located at the bottom and a cylinder rotating disk d17 located above the turning shaft d16. The rotation of the turning shaft d16 can be controlled by a motor-pulley assembly. Since the two ends of the hanging belt are respectively placed in a group of hanging belt steering devices, the cylinder rotating disk d17 moves downward under the control of the cylinder to limit the end of the hanging belt to the turning shaft d16, and the turning shaft d16 realizes the rotation of the two ends of the hanging belt when it rotates.

[0050] Among them, the hanging strap welding device d9 can use a motor-ultrasonic welding component to weld the two ends of the hanging strap to the fabric.

[0051] The sliding frame d1 is also equipped with a first tensioning and adjusting component d18 distributed between the hanging tape coiling rack d10 and the hanging tape cutting device d13. The first tensioning and adjusting component d18 includes a first adjusting plate d13. One end of the first adjusting plate d13 is hinged to the sliding frame d1. A plurality of first pull-down pulleys d7 are provided on the first adjusting plate d13. The plurality of first pull-down pulleys d7 are distributed in sequence along the axis direction of the first adjusting plate d13. The first tensioning and adjusting component d18 also includes a plurality of first pull-up pulleys d4 distributed above the first adjusting plate d13. The plurality of first pull-up pulleys d4 are respectively hinged to the sliding frame d1. A weight-reducing hole is provided on the first adjusting plate d13. The strap is alternately wound around the first upper pulley d4 and the first lower pulley d7. Under the gravity of the first adjustment plate d13 and the tension of the strap itself, the first adjustment plate d13 rotates around the hinge with the sliding frame d1 to adapt to the tension change of the strap and adjust the tension. Further, by setting a weight-reducing hole, it is prevented that the gravity of the first adjustment plate d13 is too large, causing excessive stretching of the strap.

[0052] The working principle of the strap connection mechanism d is as follows: during the reciprocating sliding process, the strap pulling device d12 pulls the strap from the strap coiling rack d10 to the strap steering device d11, and the strap cutting device d13 cuts the strap to a specific length according to the actual needs, and then the strap steering device d11 rotates the two ends of the strap to the correct angle, and then the strap welding device d9 hot-welds the two ends of the strap to the fabric. In summary, during the reciprocating sliding process of the sliding rack d1, the strap welding device d9, the strap coiling rack d10, the strap steering device d11, the strap pulling device d12, and the strap cutting device d13 all follow the sliding rack d1 to reciprocate and slide. During the hot welding process of the strap, the fabric does not need to stop being transported. After each hot welding is completed, the sliding rack d1 returns to the initial position under the control of the fourth motor d8 to perform the next strap hot welding. Compared with the prior art, the bib machine designed in this embodiment does not need to be stopped for cutting, and also does not need to be stopped for hot welding of the hanging straps, thereby further improving production efficiency.

[0053] Since the left strap connection mechanism e and the right strap connection mechanism f have the same structure and are symmetrically distributed, only the right strap connection mechanism f will be explained in detail below. The left strap connection mechanism e and the right strap connection mechanism f have the same working principle, and the two are carried out simultaneously. When the hot welding of the right strap is completed, it means that the hot welding of the left strap is also completed.

[0054] The right strap connecting mechanism f includes a draw plate f1 fixed on the frame, a strap roll rack f2 installed above the draw plate f1, a first clamping component f3, a strap cutting component f4, a second clamping component f5, and a welding component f6 are arranged in sequence below the draw plate f1 along the fabric transport direction, and a second tensioning adjustment component f7 is arranged above the draw plate f1.

[0055] The strap plate f1 is equipped with a strap pressing component f8 distributed between the coil rack f2 and the clamping station. The strap pressing component f8 includes a strap pressing plate f9. The strap pressing plate f9 is provided with a strap inlet at one end, a strap pressing channel in the middle, and a strap outlet at the other end. The two ends of the strap pressing channel are respectively connected to the strap inlet and the strap outlet. The right strap enters from the strap inlet, passes through the strap pressing channel, and finally passes through the strap outlet, which compacts the right strap and prevents the right strap from being pulled back. The strap pressing plate f9 is connected to the first sheet metal f10, and the side of the first sheet metal f10 is connected to the strap plate f1 by screws. The first sheet metal f10 is provided to facilitate the installation of the strap pressing plate f9. The belt outlet end of the belt pressing plate f9 is provided with an upper pressing wheel f11 and a lower pressing wheel f12 which are relatively distributed up and down. The end of the lower pressing wheel f12 is hinged on the belt pulling plate f1. A rotating shaft f13 is provided in the middle of the upper pressing wheel f11. The two ends of the rotating shaft f13 are respectively linked with connecting blocks f14. A supporting block f15 is provided between the two groups of connecting blocks f14. The supporting block f15 is linked with a first cylinder f16. The upper pressing wheel f11 and the lower pressing wheel f12 which are relatively distributed up and down are provided to further compact the right strap and improve the transportation stability of the right strap. The first cylinder f16, the supporting block f15, the connecting block f14 and the rotating shaft f13 are further provided to facilitate adjusting the position of the upper pressing wheel f11 according to actual conditions, so as to better cooperate with the lower pressing wheel f12 to compact the right strap.

[0056] The second tension adjustment component f7 includes a second adjustment plate f17, one end of which is hinged on the draw plate f1, and a plurality of second pull-down pulleys f18 are arranged on the second adjustment plate f17, and the plurality of second pull-down pulleys f18 are sequentially spaced and distributed along the axis direction of the second adjustment plate f17, and the second tension adjustment component f7 also includes a plurality of second upper pulleys f19 distributed above the second adjustment plate f17, and the plurality of second upper pulleys f19 are respectively hinged on the draw plate f1, and a weight reduction hole f20 is also arranged on the second adjustment plate f17. The right strap is alternately wound around the second upper pulley f19 and the second lower pulley f18 in sequence, and under the action of the gravity of the second adjustment plate f17 and the tension of the right strap itself, the second adjustment plate f17 will rotate around the hinge with the draw plate f1, so as to adapt to the tension change of the right strap and realize the adjustment of tension. Furthermore, by providing the weight-reducing hole f20, it is possible to avoid excessive gravity of the second adjustment plate f17, thereby preventing the right strap from being overstretched.

[0057] The end of the first clamping member f3 is linked to the fourth cylinder f21 and driven by the fourth cylinder f21 to reciprocate along the cloth conveying direction.

[0058] The strap cutting component f4 includes a shearing tool f22 and a shearing fitting assembly. The shearing tool f22 is distributed between the shearing fitting assembly and the second clamping member f5. The shearing fitting assembly includes a mounting plate f23 fixed at one end on the pull strap plate f1. A second cylinder f24 is connected above the mounting plate f23. The output end of the second cylinder f24 is linked to a pressure plate f25. A shearing fitting block f47 corresponding to the pressure plate f25 is connected below the mounting plate f23. A through hole is passed through the middle of the mounting plate f23. The shearing tool f22 includes an upper scissor blade, a lower scissor blade, and a third cylinder f26. The same end of the upper scissor blade and the lower scissor blade are coaxially hinged. The end of the upper scissor blade is linked to an upper connecting rod f27, and the end of the lower scissor blade is linked to a lower connecting rod f28. The output end of the third cylinder f26 is hinged to the ends of the upper connecting rod f27 and the lower connecting rod f28 at the same time, and the body of the third cylinder f26 is connected to a second sheet metal f29. When the right strap is cut, the second cylinder f24 pushes the pressure plate f25 to press down one end of the right strap. Since one end of the right strap has been hot-welded to the fabric, both ends of the right strap are limited. When the shears f22 cut the right strap, the length of the cut right strap can be accurately controlled. The working principle of the shears f22 is as follows: when the output end of the third cylinder f26 is extended, the ends of the upper connecting rod f27 and the lower connecting rod f28 located away from the third cylinder f26 are separated from each other, and the upper scissor blades and the lower scissor blades are in an open state. When the output end of the third cylinder f26 is retracted, the ends of the upper connecting rod f27 and the lower connecting rod f28 located away from the third cylinder f26 are close to each other, and the upper scissor blades and the lower scissor blades are in a gathered state. This process realizes the shearing of the right strap. The second sheet metal f29 is further designed to facilitate the installation of the third cylinder f26.

[0059] The upper part of the second clamping member f5 is linked to a transmission seat f30 through a bearing, a first motor f31 is installed on the side of the transmission seat f30, the output end of the first motor f31 is linked to a first belt pulley f32, the first belt pulley f32 is linked to a first transmission belt f33, and the second clamping member f5 is linked to the first transmission belt f33 by setting a second belt pulley f34. By setting the first motor f31, the first belt pulley f32, the second belt pulley f34, and the first transmission belt f33, the rotation of the second clamping member f5 can be controlled to realize the steering of the right strap and to be hot-welded on the fabric in the correct direction.

[0060] The transmission seat f30 is fixedly connected with a slide seat f35, and the slide seat f35 is linked with a second transmission belt f36. The pull plate f1 is installed with a second guide rail f37 arranged parallel to the second transmission belt f36. The slide seat f35 is slidably connected with the second guide rail f37. The two ends of the second transmission belt f36 are respectively linked with third pulleys f38, and the third pulley f38 is linked with a second motor f39. The second motor f39 drives the first clamping member f3 to move between the strap cutting member f4 and the welding member f6 through the second transmission belt f36. The second clamping member f5 can reciprocate between the strap cutting member f4 and the welding member f6 under the action of the second transmission belt f36, the second guide rail f37 and the slide seat f35.

[0061] The frame is rotatably connected with a pull-down roller f40 and a lifting roller f41. The pull-down roller f40 and the lifting roller f41 are both arranged perpendicular to the cloth transport mode. The pull-down roller f40 is arranged below the pull-belt plate f1 and there is a gap between the two. The lifting roller f41 is arranged between the pull-down roller f40 and the welding component f6. When the cloth enters the left strap connection mechanism e and the right strap connection mechanism f, it will be pulled down by the pull-down roller f40 until it is away from the first clamping member f3, the strap cutting member f4, and the second clamping member f5, so as to avoid the first clamping member f3, the strap cutting member f4, and the second clamping member f5 from interfering with the cloth during the working process; and when the cloth passes through the pull-down roller f40 and enters the lifting roller f41, the lifting roller f41 lifts the cloth to the same height as the welding component f6, so as to facilitate the hot welding of the cloth with the left strap and the right strap, which is also the reason why the second clamping member f5 does not need to be lifted up and down.

[0062] The welding component f6 includes an ultrasonic ironing head f42 and a pressing block f43 distributed at the welding station. The ultrasonic ironing head f42 is distributed at the lower end of the pressing block f43. One end of the pressing block f43 is provided with multiple groups of pressing teeth, and the other end is linked with a melting gear shaft f44. The middle part of the melting gear shaft f44 is hinged with the pull plate f1 through a bearing. One end of the melting gear shaft f44 is provided with a strip groove f45, and the middle part of the strip groove f45 is provided with a screw hole. The other end of the pressing block f43 is inserted into the strip groove f45, and the other end of the pressing block f43 is also provided with a strip hole f48 corresponding to the screw hole. The other end of the melting gear shaft f44 is linked with a third motor f46 through a pulley assembly. The third motor f46 controls the rotation of the melting gear shaft f44 through the pulley assembly, and the melting gear shaft f44 drives the pressing block f43 to rotate. Whenever the pressing block f43 rotates to the bottom, the pressing teeth will heat and weld the right strap to the fabric. Among them, the design of the strip groove f45, the screw hole and the strip hole f48 can adjust the relative position of the pressing block f43 and the melting gear shaft f44 according to actual conditions, so that the pressing block f43 can accurately perform hot welding on the right strap and the fabric.

[0063] The working principle of the right strap connection mechanism f is as follows: the strap coil rack transports the right strap in an orderly manner, and the right strap first enters the strap pressing component f8, which compacts the right strap to prevent the right strap from being pulled back; after entering the second tensioning adjustment component f7, it then enters the first clamping component f3, and the first clamping component f3 transports the right strap to the second clamping component f5, and the second clamping component f5 pulls the right strap to the welding component f6 for welding, wherein the strap cutting component f4 cuts the right strap according to the actual situation. It can be seen from this that when the left and right straps are hot-welded, the fabric does not need to be stopped for transportation. Compared with the prior art, not only does cutting and strap hot-welding not require shutdown, but also the hot-welding of the left and right straps does not require shutdown. Therefore, the fabric does not need to be stopped for transportation during the entire process of fabric production, which greatly improves production efficiency. Furthermore, compared with the prior art, the rotation response speed of the second clamping member f5 is fast, and there will be no jamming, the production efficiency is higher, and the rotation angle can also be adjusted according to the actual situation. Furthermore, the left strap connection mechanism e and the right strap connection mechanism f designed in the present application abandon the "lifting" components in the prior art. The second clamping member f5 only needs to move back and forth along the cloth transportation direction and make a turning motion, without lifting up and down, which also reduces the risk of damage to the second clamping member f5 and prolongs its service life. Compared with the prior art, the right strap does not need to be folded in half, which reduces the process.
