The lifting and conveying mechanism 81 has the same conveying direction as the electric slide rail 113, that is, after the clamping and fixing mechanism fixes the pillow to be sealed, the electric slide rail 113 drives the clamping and fixing mechanism and the pillow to move toward the sewing device 112, and at this time, the lifting and conveying mechanism 81 holds other parts of the pillow and moves synchronously and in the same direction. When the pillow moves to the sewing device 112, the controller controls the sewing device 112 to sew and seal the moving pillow.

[0027] As a preferred solution, the clamping and fixing mechanism includes a vertical mounting plate 11 arranged on an electric slide rail 113, two groups of clamping assemblies 2 are arranged on the vertical mounting plate 11, a pressure plate assembly 3 is arranged on the vertical mounting plate 11 between the two groups of clamping assemblies 2, and the pressure plate assembly 3 cooperates with the clamping assembly 2 to flatten the side of the pillow to be sealed. The clamping assembly 2 includes a transverse slide rail 21 arranged on the vertical mounting plate 11, a first movable mounting plate 4 slidably connected to the transverse slide rail 21, a vertical slide rail 22 arranged on the first movable mounting plate 4, a second movable mounting plate 41 slidably connected to the vertical slide rail 22, and an upper clamping plate 5 fixedly arranged on the second movable mounting plate 41, the first movable mounting plate 4 is provided with a lower clamping plate 51 close to the workbench 1, and the upper clamping plate 5 and the lower clamping plate 51 correspond to each other up and down to form a clamp. The upper clamping plate 5 includes an integrally formed first fixing portion 53 and a first clamping portion 54, wherein the first fixing portion 53 is fixedly connected to the second movable mounting plate 41, and the lower clamping plate 51 includes an integrally formed second fixing portion 55 and a second clamping portion 56, wherein the second fixing portion 55 is fixedly connected to the first movable mounting plate 4; the corresponding first clamping portion 54 and second clamping portion 56 are combined to form a positioning clamping opening. Preferably, an anti-slip portion is provided on the opposite sides of the first clamping portion 54 and the second clamping portion 56, and the anti-slip portion may be an anti-slip pad, or an anti-slip groove or anti-slip particles directly provided on the clamping portion. The opening of the clamping opening faces forward, and the clamping openings on the two sets of clamping assemblies 2 extend inward to the same depth, which is determined according to the sewing position of the side of the pillow to be sealed. The operator only needs to extend the two ends of the side of the pillow to be sealed into the clamping opening and close to the deepest inner wall of the clamping opening, and then control the upper clamping plate 5 and the lower clamping plate 51 to clamp, which can basically ensure that the pillow is fixed in an accurate position, thereby reducing the requirements for the operator's proficiency.

[0028] A first telescopic cylinder 6 is provided on one side of the first movable mounting plate 4. The end of the telescopic rod of the first telescopic cylinder 6 is fixedly connected to the second movable mounting plate 41 through a connecting plate and drives the second movable mounting plate 41 to move vertically.

The sewing opening 34 is the position where the sewing machine performs sewing and sealing, so the position of the sewing opening 34 and the positions of the clamping openings on both sides need to correspond to each other. The mounting plate 32 and the pressing plate 33 are connected by a first rotating connector 35 and can achieve relative rotation. The first rotating connector 35 can be a hinge or a rotating shaft structure, so that the mounting plate 32 and the pressing plate 33 can rotate stably.

[0030] The mounting plate 32 is provided with a third telescopic cylinder 62, and the pressing plate 33 is provided with a connecting block 36. The end of the telescopic rod of the third telescopic cylinder 62 is rotatably connected to the connecting block 36 through the second rotating connecting member 37, and the rotation of the pressing plate 33 is controlled by the telescopic rod of the third telescopic cylinder 62. The first telescopic cylinder 6, the second telescopic cylinder 61 and the third telescopic cylinder 62 can be electric telescopic cylinders or pneumatic telescopic cylinders, which are convenient for automatic control. The second rotating connecting member 37 is a joint bearing provided at the end of the telescopic rod of the third telescopic cylinder 62, and the connecting block 36 is connected to the joint bearing through a connecting shaft. The joint bearing can rotate relative to the connecting shaft, so that during the telescopic rod extension and retraction process of the third telescopic cylinder 62, the pressing plate 33 is driven to rotate upward to open or rotate downward to press down.

[0031] In addition, two third telescopic cylinders 62 can be arranged on the mounting plate 32. When in use, the two third telescopic cylinders 62 are controlled to work synchronously at the same time, so that the rotation structure of the pressure plate 33 can be more stable, and the force of opening and pressing down can be greater. A rotating mounting seat 7 is arranged on the mounting plate 32, and the third telescopic cylinder 62 is rotatably connected to the rotating mounting seat 7, and the rotatable direction of the third telescopic cylinder 62 is the same as the rotatable direction of the pressure plate 33. The design of the rotating mounting seat 7 enables the third telescopic cylinder 62 to rotate at a certain angle when required, so that the rotation control of the pressure plate 33 is smoother. The reinforcement plate can be fixed on one side of the rotating mounting seat 7, and the reinforcement plate can improve the installation firmness of the rotating mounting seat 7 and the third telescopic cylinder 62.

[0032] As another preferred solution, the lifting and conveying mechanism 81 includes a mounting bracket 82 arranged on one side of the machine 111, a belt conveying device 83 mounted on the top of the mounting bracket 82, and a protective baffle 88 and a guide baffle 89 respectively arranged on both sides of the mounting bracket 82.

[0033] Four pulleys may be provided on each of the first driving shaft 831 and the first driven shaft 832. A transmission belt 833 is provided between the two corresponding pulleys on the first driving shaft 831 and the first driven shaft 832, that is, a plurality of transmission belts 833 are provided in parallel, which saves more materials than the integral transmission belt. The first driving shaft 831 and the first driven shaft 832 are both rotatably mounted on the mounting bracket 82 through a mounting seat. When the first driving shaft 831 rotates, the first driven shaft 832 can rotate synchronously through the transmission belt 833. A first driving motor 9 is provided on the side of the machine 111, and a reinforcement frame 911 is provided on the machine 111 between the first driving shaft 831 and the first driving motor 9. The first driving shaft 831 passes through the reinforcement frame 911 and is connected to the output shaft of the first driving motor 9. The rotation of the driving shaft 51 is controlled by the driving motor 7.

[0034] The protective baffle 88 includes an integrally formed top baffle 881 and a first side baffle 882, wherein the top baffle 881 is arranged horizontally and the first side baffle 882 is arranged vertically.

The guide baffle 89 includes an integrally formed guide plate 891 and a second side baffle 892, wherein the second side baffle 892 is arranged vertically, and the guide plate 891 is arranged obliquely toward the belt conveying device 83 and the highest point of the guide plate 891 is lower than the conveying plane of the belt conveying device 83. The guide plate 891 has two functions. One is to prevent the operator from touching the side of the conveying device, just like the protective baffle 88; the other is that when the pillow moves to the guide baffle 89, the controller controls the clamping and fixing mechanism to loosen the sealed side of the pillow, and the pillow will slide forward under the guidance of the guide plate 891 to achieve automatic unloading.

[0035] The machine 111 is provided with a second driving shaft 921, two second driven shafts 922 connected to the second driving shaft 921 by belts, and a sliding mechanism 94 corresponding to the two second driven shafts 922 and arranged on one side. The sliding mechanism 94 includes a sliding track 942 and a sliding bracket 941 slidably connected to the sliding track 942. A connecting clamp 943 is provided on the side of the sliding bracket 941. The connecting clamp 943 is fixedly connected to the adjacent belt so that the belt can drive the sliding bracket 941 to move. The machine 111 is provided with a driving shaft mounting seat 101 and a driven shaft mounting seat 102. The second driving shaft 921 is rotatably mounted on the driving shaft mounting seat 101, and the second driven shaft 922 is rotatably mounted on the driven shaft mounting seat 102. There are generally two driving shaft mounting seats 101, which are respectively arranged at both ends of the second driving shaft 921. In addition, a reinforcement seat can be arranged between the two driving shaft mounting seats 101 to improve the installation stability of the second driving shaft 921. The two second driven shafts 922 can be connected to the second driving shaft 921 by belts, and rotate synchronously under the drive of the second driving shaft 921. A rotating shaft can also be connected between the two second driven shafts 922 to further ensure the consistency of the two second driven shafts 922 during rotation. A second driving motor 99 is provided on one side of the driving shaft mounting seat 101, and the output shaft of the second driving motor 99 is connected to the second driving shaft 921.

[0036] The sliding bracket 941 includes a sliding base 98 and a fixed bracket 982 arranged on the top of the sliding base 98. A fixing plate 983 for the electric slide rail 113 is arranged on the front side of the top of the fixed bracket 982. The top of the sliding base 98 is provided with a first mounting plane 984, a second mounting plane 985 and a third mounting plane 986 from high to low. The first mounting plane 984, the second mounting plane 985 and the third mounting plane 986 are all provided with mounting holes. The fixed bracket 982 is installed on the first mounting plane 984 or the second mounting plane 985. The third mounting plane 986 is detachably provided with the connecting clamp plate 943. The fixed bracket 982 and the electric slide rail 113 can have different mounting positions for adjustment, and the mounting holes can also be provided in multiple groups, so as to adjust the mounting position forward and backward. The bottom surface of the connecting clamp plate 943 is provided with a latching tooth, and the corresponding belt is fixed between the connecting clamp plate 943 and the sliding base 98. The design of the latching tooth can increase the connection firmness between the belt and the connecting clamp plate 943, and effectively prevent loosening. In addition, at positions corresponding to the two sliding brackets 941 on the workbench 1, through grooves for the sliding brackets 941 to slide forward and backward are provided, so that the sliding brackets 941 can smoothly drive the electric slide rails 113 to achieve forward and backward adjustment.

[0037] Working principle: During operation, the operator first extends the two ends of the side of the pillow to be sealed into the clamping opening of the clamping and fixing mechanism and close to the inner wall of the deepest part of the clamping opening, then controls the upper and lower clamps to clamp, and then the second telescopic cylinder controls the clamping assembly to move outward a certain distance, that is, the two sets of clamping assemblies move in opposite directions, and the sides of the pillow to be sealed are properly tightened and not easy to loosen during the reverse movement of the two sets of clamping assemblies. Then, the third telescopic cylinder on the pressing plate assembly controls the pressing plate to press down and flatten the pillow to be sealed, so that the pillow is clamped and fixed before sewing and sealing. The next step is that the controller controls the second drive motor to work, moves the electric slide to a position matching the sewing equipment, and then controls the electric slide and the lifting and conveying mechanism to move synchronously to move the pillow to be sealed toward the sewing equipment. When the pillow moves to the bottom of the sewing equipment, the suture needle on the sewing equipment passes through the sewing opening to sew and seal the side of the pillow. During the sewing and sealing process, the pillow continues to move until the sew is completed. After the pillow is sewn, it continues to move forward driven by the electric slide rail and the lifting and conveying mechanism until it reaches the guide baffle. The two sets of clamping components on the clamping and fixing mechanism are released, and the pillow falls down under the guidance of the guide baffle to be collected. Finally, the controller controls the electric slide rail and other components to reset so that the next pillow can be sewn and sealed.
