Abstract
Description
Technical Field
[0001] This application relates to the field of reporting bedding production equipment, and in particular to a fully automatic bedding machine for attaching belts, labels, and covers. Background Technology
[0002] During the production of duvet covers or bedding, three sides of two square layers of fabric need to be sewn together. Several straps for securing the duvet insert also need to be sewn along the inner edge of the duvet cover. A label also needs to be sewn onto the inner layer. The production process typically includes cutting the two layers of fabric, aligning and overlapping them, sewing three sides together, and finally attaching the label and straps. Since the two layers of fabric need to be removed from two separate fabric rolls, overlapped, and laid flat, they also require sewing and cutting processes. However, in actual production, it has been found that the fabric is prone to wrinkling, resulting in uneven seams and low product quality in the duvet covers or bedding. Summary of the Invention
[0003] In order to improve the product quality of duvet covers or bedding, this application provides a fully automatic duvet cover and bedding attaching machine.
[0004] This application provides a fully automatic machine for attaching covers and quilts, employing the following technical solution:
[0005] A fully automatic quilt cover and bedding feeding machine includes a two-layer fabric feeding mechanism, a smoothing mechanism, a two-side sewing mechanism, a quilt strap feeding mechanism, a label feeding mechanism, and a cutting mechanism. The two-layer fabric feeding mechanism unloads two layers of fabric from two raw fabric rolls respectively. The smoothing mechanism smooths the overlapping two layers of fabric. The two-side sewing mechanism sews the sides of the two layers of fabric. The label feeding mechanism places a label on the two layers of fabric. The quilt strap feeding mechanism places the quilt strap on the two layers of fabric. The label and quilt strap placed on the two layers of fabric are sewn onto the two layers of fabric by the two-side sewing mechanism. The cutting mechanism cuts the two layers of fabric and simultaneously sews the third side of the two layers of fabric.
[0006] By adopting the above technical solution, this solution provides a complete production line. First, two layers of fabric are unloaded from two raw material rolls, then overlapped. A smoothing mechanism smooths the overlapping layers, facilitating subsequent processing. A tape feeding structure and a label feeding mechanism place the tape and label onto the two layers of fabric. Then, a two-sided sewing mechanism sews the tape and label to both sides of the two layers of fabric while simultaneously sewing the sides together. Finally, the two sewn layers are cut, and the cut edges are sewn together to obtain a three-sided sewn duvet cover or quilt. This solution achieves a fully automated production line for duvet covers and quilts, incorporating a fabric smoothing process that requires no manual intervention, significantly reducing labor costs. Furthermore, due to mechanical production, high precision and smooth stitching result in high product quality and high production efficiency.
[0007] Optionally, the smoothing mechanism includes a smoothing frame, a bottom smoothing component and a top smoothing component mounted on the smoothing frame; the bottom smoothing component includes two sets of bottom smoothing pulley structures and two bottom smoothing motors, each set of bottom smoothing pulley structures includes two first synchronous pulleys rotatably connected to the smoothing frame and a first synchronous belt tensioned to the two first synchronous pulleys, the four first synchronous pulleys of the two sets of bottom smoothing pulley structures are arranged in a straight line, the axes of the four first synchronous pulleys are parallel, and the two bottom smoothing motors drive the top surfaces of the two first synchronous belts to move away from each other;
[0008] The top surface smoothing assembly includes two sets of top surface smoothing pulley belt structures and two top surface smoothing motors. Each set of top surface smoothing pulley belt structures includes two second synchronous pulleys rotatably connected to the smoothing frame and a second synchronous belt tensioned to the two second synchronous pulleys. The four second synchronous pulleys of the two sets of top surface smoothing pulley belt structures are arranged in a straight line, and the axes of the four second synchronous pulleys are parallel. The two top surface smoothing motors drive the bottom surfaces of the two second synchronous belts to move away from each other.
[0009] The bottom sides of the two layers of fabric abut against the top surfaces of the two first synchronous belts, and the top surfaces of the two layers of fabric abut against the bottom surfaces of the two second synchronous belts.
[0010] By adopting the above technical solution, because the top surfaces of the two first synchronous belts of the bottom surface smoothing component move away from each other, and the bottom surfaces of the two second synchronous belts of the two top surface smoothing components move away from each other, the bottom surfaces of the two layers of fabric contact the top surfaces of the two first synchronous belts, and when the top surfaces contact the top surfaces of the two second synchronous belts, the first and second synchronous belts smooth the center of the two layers of fabric towards the opposite sides of the two layers of fabric, thereby achieving the smoothing of the double-layer fabric and facilitating subsequent processing.
[0011] Optionally, the outer rings of the first and second synchronous belts are provided with a plurality of drive teeth. The top surface smoothing motor and the bottom surface smoothing motor are fixed on the smoothing frame. Drive wheels are coaxially fixed on the motor shafts of the top surface smoothing motor and the bottom surface smoothing motor, and a plurality of drive teeth are evenly arranged circumferentially on the drive wheels. The drive teeth on the drive wheels mesh with the drive teeth on the first and second synchronous belts.
[0012] By adopting the above technical solution, the drive teeth are set on the outer side of the first synchronous belt and the second synchronous belt. The drive teeth have the function of increasing friction, which makes it easier to smooth the top and bottom surfaces of the two layers of fabric. At the same time, the drive teeth also have the function of transmission, which facilitates the movement of the first synchronous belt and the second synchronous belt.
[0013] Optionally, the smoothing frame is equipped with two edge-cutting machines, which cut off the two edges of the smoothed two layers of fabric.
[0014] By adopting the above technical solution, the edge-cutting machine cuts off the two sides of the two layers of fabric after smoothing, making the edges of the two layers of fabric smoother. Simultaneously, during the production of the greige fabric, to prevent the edges from slipping, the sides of the greige fabric are ironed, causing the edges to shrink inwards and increasing the density of the fabric edges, thus preventing slippage. However, this can lead to wrinkles in the entire piece of fabric, and the fabric edges being too tightly woven, making it impossible to achieve horizontal flatness during vertical cutting. Therefore, it is necessary to trim the edges of the greige fabric to facilitate alignment of the two sides of the double-layered fabric and to prevent wrinkles when the double-layered fabric is overlapped. The smoothing mechanism smooths the double-layered fabric from the center outwards during smoothing, which also facilitates the edge-cutting machine to simultaneously cut off any excess wrinkles and shrunken sides after smoothing, making the sides of the two layers of fabric smooth.
[0015] Optionally, the two-layer fabric feeding mechanism includes a feeding frame, two placing components for placing fabric rolls, and two sensing structures disposed on the feeding frame; the placing components include a placing base frame, several placing rollers and a placing motor, the several placing rollers are parallel to each other, the several placing rollers are rotatably connected to the placing base frame, the several placing rollers are arranged in an arc shape, and the placing motor drives one of the placing rollers to rotate.
[0016] The sensing structure senses the tension of the fabric being unloaded from the two raw material rolls. When the fabric being unloaded from the raw material rolls is in a tense state, the placement motor rotates, causing the raw material rolls to rotate, thereby causing the fabric to exit the raw material rolls and relax the unloaded fabric.
[0017] By adopting the above technical solution, two sensing structures each detect the tension of a piece of fabric. When the fabric retracting from the raw fabric roll is taut, it indicates that the raw fabric roll needs to be unloaded. After detecting the fabric tension, the sensing structure transmits a signal to the controller. The controller drives the placement motor to rotate, causing the raw fabric roll to rotate and retract the next section of fabric. At this point, the fabric is in a loose state, ensuring that only the amount of fabric used is retracted from the original fabric roll. Even if the downstream equipment of the production line stops, the problem of continuous unloading of the raw fabric roll located at the front position will not occur.
[0018] Optionally, the sensing structure includes two U-shaped rods and two sensors. The two ends of the two U-shaped rods are rotatably connected to the feeding frame, and the ends of the U-shaped rods away from the feeding frame hang down due to gravity. The feeding frame is provided with two support members. The fabric passes around the bottom ends of the two U-shaped rods one by one and then passes around the top surfaces of the two support members one by one. The top surfaces of the support members are positioned higher than the bottom ends of the two U-shaped rods.
[0019] When the raw material fabric roll is taut, the fabric drives the U-shaped rod to rotate away from or towards the sensor; the two pieces of fabric overlap after passing around the two support members respectively.
[0020] By adopting the above technical solution, because the top surface of the support is higher than the bottom of the two U-shaped rods, when the fabric is taut, the fabric drives the U-shaped rods to rotate away from or towards the sensor, thereby causing the placement motor to drive the original fabric roll to unwind. This unwinding method ensures that as long as the fabric reaches a taut state, the U-shaped rods can rotate. If the subsequent equipment continues to use fabric, the U-shaped rods can continue to rise, providing a buffer space and preventing the fabric from being deformed or damaged by excessive force.
[0021] Optionally, the conveyor belt feeding mechanism includes a conveyor belt straightening component, a conveyor belt cutting component, and a conveyor belt conveying component; the conveyor belt straightening component straightens the conveyor belt, the conveyor belt cutting component cuts the straightened conveyor belt, and the conveyor belt conveying component transports the cut conveyor belt to the two side sewing mechanisms for sewing onto two layers of fabric.
[0022] By adopting the above technical solution, the raw material of the tape is a continuous ball of yarn. Therefore, the tape needs to be flattened first, then cut to the required length, and finally transported to the designated position of the double-layer fabric and sewn by the sewing mechanism on both sides.
[0023] Optionally, the label feeding mechanism includes an automatic label conveying device, an automatic label folding mechanism, and a label transport component; the automatic label conveying device transports the labels, the automatic label folding mechanism folds the labels in half, and the label transport component transports the folded labels to the sewing mechanisms on both sides for sewing.
[0024] By adopting the above technical solution, automatic label sewing is achieved, making label sewing convenient.
[0025] Optionally, the two-sided sewing mechanism includes a side sewing frame and two side sewing machines mounted on the side sewing frame. The gap between the two side sewing machines allows two layers of fabric to pass through. The two side sewing machines are used to sew the opposite sides of the two layers of fabric, and simultaneously sew labels and quilting tape.
[0026] By adopting the above technical solution, the side sewing machine sews two layers of fabric while moving along the sides of the two layers, making the seams on both sides of the duvet cover or quilt neat. At the same time, it also sews labels and duvet straps, making it convenient to sew labels and duvet straps.
[0027] Optionally, the sewing mechanism includes an unfolding component and a sewing component, wherein the unfolding component unfolds the fabric, the sewing component cuts the double-layered fabric of the unfolded portion, and sews the cut edges of the double-layered fabric together.
[0028] By adopting the above technical solution, after the two sides of the two layers of fabric are cut by the edge cutting machine, the tightness of the quilt cover and bedding is the same, which makes it easy to unfold the quilt cover or bedding flat. Then, by using a cutting and sewing machine to sew and cut the third edge of the quilt cover at the same time, the fully automated production of the quilt cover or bedding can be realized.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] 1. By setting up a two-layer fabric feeding mechanism, a smoothing mechanism, a two-sided sewing mechanism, a quilt tape feeding mechanism, a label feeding mechanism, and a sewing mechanism, a fully automated production line for quilt covers and bedding can be realized. This can produce quilt covers or bedding with three-sided sewing and labels and tapes. No manual intervention is required during production, which greatly reduces labor costs. At the same time, due to mechanical production, the precision is high and the stitching is neat, resulting in good product quality and high production efficiency.
[0031] 2. By setting up a smoothing mechanism and two edge cutting machines, the smoothing mechanism smooths the double-layer fabric from the center to both sides during the smoothing process. This is also to facilitate the edge cutting machine to cut off the excess wrinkles and inward-shrinking sides at the same time after the smoothing process, so that the two layers of fabric are flat on both sides.
[0032] 3. By incorporating placement rollers, a motor, sensors, and U-shaped rods, the problem of fabric deformation or damage caused by forceful pulling is prevented. Attached Figure Description

Detailed Implementation
[0045] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.
[0046] This application discloses a fully automatic machine for attaching covers and quilts. (See also...) Figure 1The fully automatic quilt cover and bedding feeding machine includes a two-layer fabric feeding mechanism 1, a smoothing mechanism 2, a quilt cover feeding mechanism 3, a label feeding mechanism 4, a two-sided sewing mechanism 5, and a cutting mechanism 6, arranged in sequence.
[0047] Reference Figure 2 The two-layer fabric feeding mechanism 1 removes two layers of fabric from two raw material rolls and overlaps them. The two-layer fabric feeding mechanism 1 includes a feeding frame 11, two placement components 12 for placing fabric rolls, and two sensing structures 13 disposed on the feeding frame 11.
[0048] Reference Figure 2 , Figure 3 A placement assembly 12 includes a placement base 121, a plurality of placement rollers 122, and a placement motor 123. The placement rollers 122 are parallel to each other and rotatably connected to the placement base 121. The placement rollers 122 are arranged in an arc shape, with the arc shape being concave, forming a concave arc surface for placing the original fabric roll. The placement motor 123 is fixed to the placement base 121 and is located below the placement roller 122 with the lowest horizontal position. Placement timing pulleys 124 are coaxially fixed to the end of the placement roller 122 and the motor shaft of the placement motor 123. A placement timing belt 125 is tensioned and connected to two placement timing pulleys 124, so that the placement motor 123 drives the placement roller 122 with the lowest horizontal position to rotate. When the original fabric roll is placed on the concave surface formed by the plurality of placement rollers 122, the rotation of the placement motor 123 can cause the original fabric roll to be ejected from the fabric.
[0049] Reference Figure 2 The sensing structure 13 includes two U-shaped rods 131 and two sensors 132. The two ends of the two U-shaped rods 131 are rotatably connected to the loading rack 11, and the ends of the two U-shaped rods 131 away from the loading rack 11 hang down due to gravity. The two sensors 132 are fixed to the loading rack 11. When the ends of the U-shaped rods 131 away from the loading rack 11 hang down due to gravity, the bottom ends of the U-shaped rods approach the sensors 132.
[0050] Reference Figure 2 , Figure 3The feeding rack 11 is equipped with two support members 111, which are two parallel support wheels 1111. The two ends of the support wheels 1111 are rotatably connected to the feeding rack 11. Two layers of fabric pass over the bottom ends of two U-shaped rods 131 one by one, and then pass over the top surfaces of the two support wheels 1111 one by one. The top surfaces of the support wheels 1111 are higher than the bottom ends of the two U-shaped rods 131. This ensures that when the raw fabric roll is taut, the fabric contacts the bottom ends of the U-shaped rods 131, and the fabric rotates the bottom ends of the U-shaped rods away from the sensor 132. At this time, the sensor 132 transmits a signal to the controller, which drives the placement motor 123 to rotate, causing the original fabric to roll back up to the next section, thus slackening the fabric.
[0051] Reference Figure 2 After the two pieces of fabric pass around the two support wheels 1111 respectively, they come into contact with each other and overlap. The two pieces of fabric move in close contact with the support wheels 1111, making the fabric move smoothly.
[0052] Reference Figure 4 The two overlapping layers of fabric are moved to the smoothing mechanism 2. The smoothing mechanism 2 smooths the two overlapping layers of fabric. The smoothing mechanism 2 includes a smoothing frame 21, a bottom smoothing component 22 and a top smoothing component 23 disposed on the smoothing frame 21.
[0053] Reference Figure 4 The bottom surface smoothing assembly 22 includes two sets of bottom surface smoothing pulley belt structures 221 and two bottom surface smoothing motors 222. Each set of bottom surface smoothing pulley belt structures 221 includes two first synchronous pulleys 2211 rotatably connected to the smoothing frame 21 and a first synchronous belt 2212 tensioned to the two first synchronous pulleys 2211. The four first synchronous pulleys 2211 of the two sets of bottom surface smoothing pulley belt structures 221 are arranged in a straight line, the axes of the four first synchronous pulleys 2211 are parallel, and the axes of the four first synchronous pulleys 2211 are horizontal.
[0054] Reference Figure 4 The outer ring of the first synchronous belt 2212 is integrally formed with several drive teeth. Two bottom-level smoothing motors 222 are fixed on the smoothing frame 21, and the two bottom-level smoothing motors 222 are respectively located at the bottom of the two first synchronous belts 2212. A drive wheel 24 is coaxially fixed on the motor shaft of the bottom-level smoothing motor 222. Several drive teeth are evenly arranged around the drive wheel 24. The drive teeth on the first synchronous belt 2212 mesh with the drive teeth on the drive wheel 24 of the bottom-level smoothing motor 222. When the bottom-level smoothing motor 222 rotates, it drives the top surfaces of the two first synchronous belts 2212 to move away from each other.
[0055] Reference Figure 4The top surface smoothing assembly 23 includes two sets of top surface smoothing pulley belt structures 231 and two top surface smoothing motors 232. Each set of top surface smoothing pulley belt structures 231 includes two second synchronous pulleys 2311 rotatably connected to the smoothing frame 21 and a second synchronous belt 2312 tensioned to the two second synchronous pulleys 2311. The four second synchronous pulleys 2311 of the two sets of top surface smoothing pulley belt structures 231 are arranged in a straight line, with the axes of the four second synchronous pulleys 2311 parallel and horizontal.
[0056] Reference Figure 4 The outer ring of the second synchronous belt 2312 is also integrally formed with several drive teeth. Two top-surface smoothing motors 232 are fixed on the smoothing frame 21, and two bottom-surface smoothing motors 222 are respectively located on top of the two second synchronous belts 2312. A drive wheel 24 is also coaxially fixed on the motor shaft of the top-surface smoothing motor 232. Several drive teeth are evenly arranged around the drive wheel 24, and the drive teeth on the second synchronous belt 2312 mesh with the drive teeth on the drive wheel 24 of the top-surface smoothing motor 232. When the top-surface smoothing motor 232 rotates, it drives the bottom surfaces of the two second synchronous belts 2312 to move away from each other.
[0057] Reference Figure 4 The bottom surface of the second synchronous belt 2312 is higher than the top surface of the first synchronous belt 2212. The bottom sides of the two layers of fabric abut against the top surfaces of the two first synchronous belts 2212, and the top surfaces of the two layers of fabric abut against the bottom surfaces of the two second synchronous belts 2312. When the smoothing mechanism 2 is working, the top smoothing component 23 smooths the center of the upper layer of fabric to both sides, and the bottom smoothing component 22 smooths the center of the lower layer of fabric to both sides.
[0058] Reference Figure 1 , Figure 4 Two edge-cutting machines 7 are fixed on the smoothing frame 21. The edge-cutting machines 7 are fixed between the smoothing mechanism 2 and the conveyor feeding mechanism 3. After the two layers of fabric are smoothed, they move between the two edge-cutting machines 7. At the same time, the edge-cutting machines 7 cut off the two edges of the smoothed two layers of fabric, removing the wrinkles generated on both sides of the fabric after smoothing, so that the two sides of the two layers of fabric are flat.
[0059] Reference Figure 5 , Figure 6 The conveyor belt feeding mechanism 3 includes a conveyor belt base frame 31, a conveyor belt leveling assembly 32, a conveyor belt cutting assembly 33, and a conveyor belt conveying assembly 34. Two of each of the conveyor belt leveling assembly 32, conveyor belt cutting assembly 33, and conveyor belt conveying assembly 34 are provided, with each assembly corresponding to one on one side of the conveyor belt base frame 31.
[0060] Reference Figure 7The conveyor belt straightening assembly 32 straightens the conveyor belt. The conveyor belt straightening assembly 32 includes a conveyor belt feeding rack 321, a straightening plate 322, and an ironing machine 323. The conveyor belt feeding rack 321 includes a support plate 3211, a rolling frame 3212, and a conveyor belt straightening motor 3213 that drives the rolling frame 3212 to rotate. The support plate 3211 is fixed to the feeding rack 321, the rolling frame 3212 is rotatably connected to the support plate 3211, and the conveyor belt straightening motor 3213 is fixed to the support plate 3211. The motor shaft of the conveyor belt straightening motor 3213 and the rolling frame 3212 are coaxially fixed.
[0061] Reference Figure 7 The rolling frame 3212 includes two side plates 32121 and a belt-guided flat bar 32122 connecting the two side plates 32121 at both ends. The length directions of the belt-guided flat bars 32122 are parallel and horizontal. The belt-guided flat bars 32122 are arranged in a circle. The motor shaft of the belt-guided flat motor 3213 is coaxial with the circle formed by the belt-guided flat bars 32122.
[0062] Reference Figure 7 The flat plate 322 has several flat grooves 3221 extending through its surface. These grooves are arranged in a straight line along their length, with one end of the line facing the rolling frame 3212. The conveyor belt is a flat strip. The width of the flat grooves 3221 is 0-2 mm wider than the width of the conveyor belt. The conveyor belt passes over one flat groove 3221 from above, and then passes under another flat groove 3221 from below. This process is repeated to allow the conveyor belt to pass through the several flat grooves 3221.
[0063] Reference Figure 7 When the motor 3213 drives the rolling frame 3212 to rotate, the frictional force of the rolling frame 3212 on the conveyor is in the direction away from the conveyor plate 322.
[0064] Reference Figure 7 The straight line of the leveling grooves 3221 is away from the end of the rolling frame 3212 and faces the ironing machine 323. The ironing machine 323 includes a heating seat 3231, a top frame 3232, a sliding block 3233, a horizontal ironing cylinder 3232 that drives the sliding block 3233 to move horizontally, and two vertical ironing cylinders 3233 that drive the sliding block 3233 to move vertically.
[0065] Reference Figure 5 , Figure 7The heating seat 3231 is fixed to the base frame 31 of the conveyor belt. An electric heating element is embedded in the heating seat 3231 to generate heat. The top frame 3232 of the conveyor belt is fixed to the base frame 31 and is located on top of the heating seat 3231. The piston shafts of two vertical ironing cylinders 3233 are fixed to the bottom surface of the top frame 3232. A moving plate 3234 is fixed to each of the two vertical ironing cylinders 3233, and the two vertical ironing cylinders 3233 are fixed to both ends of the moving plate 3234 along its length. The length direction of the piston shafts of the two vertical ironing cylinders 3233 is vertical.
[0066] Reference Figure 7 The sliding block 3233 is slidably connected to the bottom surface of the moving plate 3234. The horizontal ironing cylinder 3232 is fixed on the moving plate 3234. The piston end of the horizontal ironing cylinder 3232 is fixed on the sliding block 3233. The piston shaft of the horizontal ironing cylinder 3232 is in the water direction, and the length direction of the piston shaft of the horizontal running cylinder is parallel to the length direction of the straight line formed by the leveling grooves 3221.
[0067] Reference Figure 7 The sliding block 3233 includes a fixed block 32331 that is slidably connected to the moving plate 3234 and a protrusion 32332 integrally formed on the bottom surface of the fixed block 32331. The top surface of the heating seat 3231 is provided with a groove 32311 for the protrusion 32332 to slide. The bottom surface of the protrusion 32332 is provided with serrations to improve the friction of the protrusion 32332 on the belt.
[0068] Reference Figure 7 When the blanket strip passing through the leveling groove 3221 is located in the groove 32311, and the sliding block 3233 is driven by the horizontal ironing cylinder 3232 and the vertical ironing cylinder 3233, the bottom wall of the protrusion 32332 presses the blanket strip and slides it a short distance away from the leveling plate 322, thereby pulling the blanket strip to move. The vertical ironing cylinder 3233 moves the moving plate 3234 upward, so that the protrusion 32332 moves upward and disengages from the blanket strip. Then the horizontal ironing cylinder 3232 drives the protrusion 32332 to move closer to the leveling groove 3221. Then the vertical ironing cylinder 3233 drives the protrusion 32332 downward, so that the protrusion 32332 presses the blanket strip again. This operation is repeated so that the blanket strip moves and irons within the groove 32311.

[0070] Reference Figure 7 , Figure 8The tape conveyor assembly 34 transports the cut tape to the two-sided sewing mechanisms 5 for sewing onto the two layers of fabric. The tape conveyor assembly 34 includes a straightening robot 341 and a conveying robot 342. The straightening robot 341 grips the ironed end of the tape and moves it away from the groove 32311, straightening the tape in the same direction as the extension of the groove 32311. The straightened tape is then gripped by the conveying robot 342, at which point the tape cutter 331 cuts the tape. The conveying robot 342 grips the cut tape and moves it toward the two-sided sewing mechanisms 5, placing the cut tape onto the double-layer fabric to be side-sewn, thus sewing the tape onto the sides of the double-layer fabric.
[0071] Reference Figure 1 , Figure 9 The label feeding mechanism 4 includes an automatic label conveying device, an automatic label folding mechanism, and a label transport component 41; the automatic label conveying device transports the labels, the automatic label folding mechanism folds the labels in half, and the label transport component 41 transports the folded labels to the two side sewing mechanisms 5 for sewing.
[0072] The label conveying device and the automatic label folding mechanism have the same structure as Embodiment 1 of the utility model patent with patent number CN215328702U, and will not be described in detail here.
[0073] Reference Figure 5 , Figure 9 The label conveying assembly 41 includes a label top frame 42, a label robot 43 movably mounted on the label top frame 42, two label vertical cylinders 44 for driving the label robot 43 to move vertically, and a label horizontal cylinder 45 for driving the label robot 43 to move horizontally. The label top frame 42 is fixed to the carrying base frame 31. The piston end of the label vertical cylinder 44 is fixed to the label top frame 42, and a label fixing plate 46 is fixed to the bottom end of the label vertical cylinder 44. The label horizontal cylinder 45 is a rodless cylinder. Both ends of the rodless cylinder are fixed to the bottom surface of the label fixing plate 46, and the moving part of the rodless cylinder is fixed to the label robot 43, enabling the label robot 43 to move horizontally and vertically.
[0074] Reference Figure 9 The label robot arm 43 moves horizontally, approaching both the automatic label folding mechanism and the two side sewing mechanisms 5. When it approaches the automatic label folding mechanism, the label robot arm 43 clamps the folded label, and then the rodless cylinder drives it to the two side sewing mechanisms 5. When attaching the label, the label vertical cylinder 44 drives the label robot arm 43 downwards, positioning the edge of the label to be sewn on the double-layered fabric, thus facilitating the sewing by the two side sewing mechanisms 5.
[0075] Reference Figure 5 The two-side sewing mechanism 5 includes a side sewing frame and two side sewing machines 51 fixed on the side sewing frame. The gap between the two side sewing machines 51 allows two layers of fabric to pass through. The two side sewing machines 51 are used to sew the opposite sides of the two layers of fabric and simultaneously sew labels and tape.
[0076] Reference Figure 10 The sewing mechanism 6 includes an unfolding component 61 and a sewing component 62. The unfolding component 61 unfolds the double-layered fabric that has been sewn on both sides. The sewing component 62 cuts the unfolded double-layered fabric and sews the cut edges of the double-layered fabric together to obtain a duvet cover or quilt with three sides sewn together and the duvet straps and labels secured.
[0077] Reference Figure 10 The unfolding assembly 61 includes a pressing structure 611, a traction structure 612, and a positioning structure 613. The pressing structure 611 includes a mounting plate 6111, two pressing rollers 6112 rotatably connected to the mounting plate 6111, and a pressing motor 6113 fixed to the pressing plate. The two pressing rollers 6112 are parallel to each other in their length direction and are both horizontal. One pressing roller 6112 presses down on the other pressing roller 6112 by its own weight. The motor shaft of the pressing motor 6113 is coaxially fixed to the end of the lower pressing roller 6112. The double-layered fabric, sewn on both sides, passes through the gap between the two pressing rollers 6112, and the two pressing rollers 6112 exert friction on the fabric. The pressing motor 6113 is not normally used. When the equipment malfunctions, the pressing motor 6113 drives the pressing rollers 6112 to rotate, pushing the double-layered fabric out between the two pressing rollers 6112.
[0078] Reference Figure 10 The traction structure 612 includes a traction base frame 6121, a movable rod 61211 slidably disposed on the traction base frame 6121, a movable manipulator 61212 slidably connected to one end of the movable rod 61211, and several fixed manipulators 61213 fixed to the other end of the movable rod 61211. The length direction of the movable rod 61211 is parallel to the length direction of the pressure rollers 6112, and the direction of movement of the movable rod 61211 is away from the two pressure rollers 6112.
[0079] Reference Figure 11The traction structure 612 also includes two traction screws 6122 and two traction motors 6123 that drive the moving rod 61211 to move. The length direction of the two traction screws 6122 is the same as the moving direction of the moving rod 61211. The ends of the two traction screws 6122 are rotatably connected to the traction base frame 6121, and the middle parts of the two traction screws 6122 are threadedly connected to the two ends of the moving rod 6121 respectively. The traction motors are fixed to the traction base frame 6121, and the two traction motors 6123 are coaxially fixed to one traction screw 6122 respectively.
[0080] Reference Figure 10 , Figure 11 The traction structure 612 also includes two manual timing pulleys 6124, a manual timing belt 6125, a manual motor 6126, two reduction timing pulleys 6127, and a reduction timing belt 6128 that drive the manipulator 61212 to slide along the length of the moving rod 61211.
[0081] Reference Figure 10 , Figure 11 Two manual timing pulleys 6124 are rotatably connected to both ends of the moving rod 61211 along its length. A manual timing belt 6125 is tensioned and connected to the two manual timing pulleys 6124. A manual motor 6126 is fixed to the bottom surface of the moving rod 61211. One reduction timing pulley 6127 is coaxially fixed to the motor shaft of the manual motor 6126, and the other reduction timing pulley 6127 is coaxially fixed to one of the manual timing pulleys 6124. A reduction timing belt 6128 is tensioned and connected to the two reduction timing pulleys 6127. The diameter of the reduction timing pulley 6127 on the manual motor 6126 is smaller than the diameter of the other reduction timing pulley 6127. A manipulator 61212 is slidably connected to the moving rod 61211 and fixed to the manual timing belt 6125, causing the manual motor 6126 to rotate and drive the manipulator 61212 to slide along the moving rod 61211.
[0082] Reference Figure 10 The movable manipulator 61212 and the fixed manipulator 61213 are used to clamp the ends of the double-layer fabric passing between the two pressure rollers 6112 and pull the double-layer fabric out from between the two pressure rollers 6112, thereby unfolding the double-layer fabric.
[0083] Reference Figure 10The positioning structure 613 is used to fix the unfolded double-layer fabric. The positioning structure 613 includes two clamping plates 6131 and two clamping cylinders 6132. The length direction of the two clamping plates is parallel to the length direction of the moving rod 61211. The two clamping cylinders 6132 are fixed on the traction base frame 6121. The pistons of the two clamping cylinders 6132 are fixed at both ends of the same clamping plate along its length direction. The other clamping plate 6131 is fixed on the traction base frame 6121. The clamping cylinder 6132 drives the two clamping plates 6131 to move away from each other or to come into contact with each other. When the passive manipulator 61212 and the fixed manipulator 61213 clamp and unfold the double-layer fabric and pull it out to a certain length, the clamping cylinder 6132 drives the two clamping plates to clamp the double-layer fabric near the pressure roller 6112, thereby facilitating the straightening of the double-layer fabric and making it easier for the sewing assembly 62 to cut the two layers of fabric and sew the third edge of the two layers of fabric at the same time.
[0084] Reference Figure 10 The sewing assembly 62 includes a fixed rod 621, a sliding seat 622, a cutting sewing machine 623, a cutting screw 624, and a cutting motor 625. The fixed rod 621 is fixed to the traction frame, and the length direction of the fixed rod 621 is parallel to the length direction of the clamping plate 6131. The sliding seat 622 is slidably connected to the fixed rod 621, and the sliding direction of the sliding seat 622 is parallel to the length direction of the fixed rod 621. The cutting sewing machine 623 is fixed to the sliding seat 622, and the cutting sewing machine 623 is provided with a sewing section for sewing double-layered fabric and a cutting section for cutting the double-layered fabric.
[0085] Reference Figure 10 The length direction of the cutting screw 624 is parallel to that of the fixed rod 621. Both ends of the cutting screw 624 are rotatably connected to the traction base 6121. The middle part of the cutting screw 624 is threadedly connected to the sliding seat 622. The cutting motor 625 is fixed to the traction base 6121, and the motor shaft of the cutting motor 625 is coaxially fixed to the end of the cutting screw 624. When the passive manipulator 61212 and the fixed manipulator 61213 clamp and unfold the double-layer fabric, and the two clamping plates clamp the double-layer fabric near the pressure roller 6112, the cutting sewing machine 623 moves while sewing and cutting the third edge of the two layers of fabric.
[0086] Reference Figure 10 The moving robot arm 61212 and the cutting and sewing machine 623 move at the same speed. When the cutting and sewing machine 623 moves, the moving robot arm 61212 moves synchronously with the cutting and sewing machine 623, so that the produced quilt cover or quilt is folded into a long strip.
[0087] Reference Figure 10When the moving rod 61211 moves away from the fixed rod 621, a conveyor table 8 is placed below the moving rod 61211 and the fixed rod 621. After the cutting and sewing machine 623 completely cuts the double-layer fabric, the moving robot 61212 and the fixed robot 61213 fold the produced quilt cover or quilt into long strips and drop them onto the conveyor table 8 to achieve automatic unloading.
[0088] The implementation principle of a fully automatic quilt cover and bedding machine according to an embodiment of this application is as follows: First, two layers of fabric are removed from two raw fabric rolls. Through the cooperation of U-shaped rod 131, sensor 132, and placement motor 123, the amount of fabric removed is adjusted to the required amount, facilitating practical use with subsequent equipment. The fabric removed from the two original fabric rolls is overlapped. A smoothing mechanism 2 is set up to smooth the two overlapping layers of fabric. Then, an edge cutting machine 7 cuts off the edges of the folds on both sides of the smoothed two layers of fabric, making the sides of the two layers of fabric flat.
[0089] The tape is first smoothed and ironed by the tape smoothing assembly 32, then cut, and finally transported to the side sewing machine 51 by the tape conveyor assembly 34 for sewing. Similarly, the label is also folded after feeding and transported to the side sewing machine 51 by the label conveyor assembly 41 for sewing. While sewing the two sides of the two layers of fabric, the side sewing machine 51 sews the tape and label to both sides of the two layers of fabric, completing the process of attaching the tape and label.
[0090] Then, the two layers of fabric sewn on both sides are unfolded by the traction structure 612 and fixed by the positioning component. The cutting sewing machine 623 is equipped with a sewing part for sewing the double-layer fabric and a cutting part for cutting the double-layer fabric. The cutting sewing machine 623 moves while sewing and cutting the third side of the two layers of fabric. Finally, the duvet cover or quilt is folded into a long strip and falls onto the conveyor table 8 to achieve automatic feeding.
[0091] In summary, the fully automatic quilt cover and bedding machine realizes a fully automated production line for quilt covers and bedding, requiring no manual intervention and greatly reducing labor costs. At the same time, due to mechanical production, the high precision and smooth stitching result in good product quality and high production efficiency.
[0092] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
