DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with embodiments:

[0028] In this embodiment, the fabric roll limiter 11 is used to limit the large lateral movement of the fabric roll during use. The fabric joining sewing machine 12 is set so that when a roll of fabric is about to be used up, its tail is sewn with the head of the next roll of fabric to avoid repeated threading, save time and improve efficiency. In the process of conveying the fabric, the first motor 21 drives the first drive roller 22 to rotate, and the fabric is pulled into the equipment at a uniform speed and conveyed backward. During the conveyance, the first fabric deviation correcting edge suction device 23 is used to preliminarily position the incoming material. The second motor 24 is the main power motor for feeding, which drives the second drive roller 25 to rotate to convey the fabric. At the same time, the first motor 21 and the second motor 24 can rotate at matching speeds to make the fabric loose or tight. The swing roller 26 can swing up and down with one fixed end as the center point. When swinging, the inclinometer 27 with a built-in gyroscope is installed on the swing arm of the swing roller to detect the angle of the swing roller 26.

When passing through the fabric trimming knife 29, the fabric trimming knife 29 can cut the incoming material into the required width and trim the two sides to make it relatively neat and beautiful.

[0029] Example 2

[0030] like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the feeding mechanism 1 includes a fabric roll limiter 11, and the surface of the fabric roll limiter 11 is fixedly connected to a fabric joining sewing machine 12 for joining two rolls of fabric end to end, the cache mechanism includes a third motor 31, a cache position sensor 33 and a cache roller 34, the surface of the third motor 31 is fixedly connected to the surface of the mounting frame, one end of the rotating shaft of the third motor 31 is fixedly connected to a third driving roller 32, the surface of the cache position sensor 33 is fixedly connected to the surface of the mounting frame, the cutting and forming mechanism 4 includes a cloth pulling clamp 41 and an edge detection sensor 42 driven by a servo motor, the edge detection sensor 42 is installed on the surface of the mounting frame, and an angle forming member 43 is arranged inside the mounting frame, fixed pressing members 44 are arranged on both sides of the angle forming member 43 and on the surface of the mounting frame, and a product conveying clamp 45 is arranged above the angle forming member 43 and on the surface of the mounting frame.

[0031] In this embodiment, the third driving roller 32 is driven to rotate by the third motor 31 and is responsible for dragging the fabric backward for transportation. At the same time, three cache position sensors 33, i.e., upper, middle and lower, are used for real-time detection and feedback signals to trigger the next action. When the fabric is transported to the cutting and forming mechanism 4, the cloth pulling clamp 41 is driven by the servo motor to grab one end of the fabric, and then moves to the specified position. After stopping, the edge detection sensor 42 is driven by the belt module to move horizontally after the fabric stops, and the position of both side edges of the fabric is found. After confirming the position, a signal is sent to move the corner forming part 43 to the specified position, so that the corner forming can be more accurately performed. Subsequently, the fabric is cut by the cutting knife, and then the corner of the bed sheet is clamped by the product conveying clamp 45, and it is conveyed to the next station.

[0032] Example 3

[0033] like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the corner cutting and marking mechanism 5 includes a conveying upper belt lifting wheel 51, a step 52 is arranged below the conveying upper belt lifting wheel 51, the surface of the step 52 is overlapped with the fabric 53, the surface of the conveying upper belt lifting wheel 51 is overlapped with the conveying upper belt 54, a cutting machine 55 is fixedly connected to the surface of the mounting frame behind the step 52, a left upper marking machine 56 is arranged behind the cutting machine 55, and a right upper marking machine 57 is arranged behind the left upper marking machine 56, and the curling sewing mechanism 6 includes a curling machine 61, the curling machine 61 is arranged on the surface of the mounting frame, a sewing machine 62 is arranged behind the curling machine 61 and on the surface of the mounting frame, and a rear-stage conveying belt total power unit 63 is arranged behind the sewing machine 62 and on the surface of the mounting frame.

[0034] The product conveying gripper 45 is opened and quickly retreated, extracted from the product, and lifted a certain distance. At this time, the fabric follows the belt to be conveyed to the next station, comes down from the step, and forms a height difference with the product conveying gripper 45, so that the fabric is smoothly conveyed to the next station 3, and the product conveying gripper smoothly returns to the previous station without interfering with each other. The corners of the fabric after bending are cut by the cutting machine 55, which is convenient for subsequent labeling and curling. Then, the left labeling machine 56 and the right labeling machine 57 are used to label the product. When curling is required, the curling machine 61 is used to curl the fabric downward when the fabric passes by, and then it is sewed and shaped by the sewing machine. At this point, the processing flow of the whole machine equipment is completed. When the customer does not need the curling process, the curling machine 61 only needs to be removed and replaced to realize the overlocking process, which is quick and convenient.

[0035] The following is a detailed description of the working principle of this new fitted sheet production line.

[0036] like Figure 1-7As shown, during processing, the fabric roll limiter 11 is used to limit the large lateral movement of the fabric roll during use. The fabric joining sewing machine 12 is set so that when a roll of fabric is about to be used up, its tail is sewn with the head of the next roll of fabric to avoid repeated threading, save time and improve efficiency. In the process of conveying the fabric, the first motor 21 drives the first drive roller 22 to rotate, and the fabric is pulled into the equipment at a uniform speed and conveyed backward. During the conveying, the first fabric deviation correcting edge suction device 23 is used to preliminarily position the incoming material. The second motor 24 is the main power motor for feeding, which drives the second drive roller 25 to rotate and convey the fabric. At the same time, the first motor 21 and the second motor 24 can rotate at matching speeds to make the fabric uniformly tight. The swing roller 26 uses one fixed end as the center point. The device can swing up and down. When swinging, the inclinometer 27 with a built-in gyroscope is installed on the swing arm of the swing roller to detect the angle of the swing roller 26. By controlling the speed of the second motor 24 and the third motor 31, the swing roller 26 is at a relatively stable angle to avoid large-scale jumping. This can make the subsequent tension of the fabric consistent and improve the qualified rate of the equipment. At the same time, the second fabric deviation correction and edge suction device 28 is used to accurately position the incoming material and determine the lateral position. When passing through the fabric trimming knife 29, the fabric trimming knife 29 can be used to cut the incoming material into the required width and trim the two sides to make it relatively neat and beautiful. The third motor 31 drives the third drive roller 32 to rotate, which is responsible for dragging the fabric backward for transportation. At the same time, the upper and middle There are three cache position sensors 33 below, which detect in real time, feedback signals, and trigger the next action. When the fabric is conveyed into the cutting and forming mechanism 4, the servo motor drives the cloth pulling clamp 41 to grab one end of the fabric, and then moves to the specified position. After stopping, the edge detection sensor 42 is driven by the belt module to move horizontally after the fabric stops, and finds the positions of the two side edges of the fabric. After confirming the position, a signal is sent to move the corner forming piece 43 to the specified position, so that the corner can be formed more accurately. Subsequently, after the fabric is cut by the cutting knife, the corner of the bed sheet is clamped by the product conveying clamp 45 and conveyed to the next workstation. When the fabric reaches the cutting corner marking mechanism 5, the conveying belt lifting wheel 51 will be lifted actively to facilitate the fabric to enter When the fabric 53 enters the designated position, the upper conveyor belt lifting wheel 51 is pressed down to clamp the fabric. At this time, the product conveying clamp 45 opens and quickly retreats, is pulled out of the product, and is lifted a certain distance. At this time, the fabric follows the belt to be conveyed to the next station, comes down from the step, and forms a height difference with the product conveying clamp 45, so that the fabric is smoothly conveyed to the next station, and the product conveying clamp smoothly returns to the previous station without interfering with each other. The bent corners of the fabric are cut by the cutting machine 55 to facilitate subsequent labeling and curling. Then, the left upper labeling machine 56 and the right upper labeling machine 57 are used to label the product. When curling is required, the curling machine 61 is used to curl the fabric downward when it passes by, and then it is sewed and shaped by the sewing machine 3. At this point, the processing flow of the whole machine equipment is completed.When the customer does not need the curling process, the curling machine 61 can be removed and replaced to achieve the overlocking process. The replacement is quick and convenient.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
