[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0025] like Figure 1-Figure 6The pillow sealing and flanging equipment shown in the figure comprises a machine table 1, a sewing mechanism 2 arranged on the machine table 1, a clamping and fixing mechanism 3 arranged on the machine table 1 on one side of the sewing mechanism 2, a front conveying mechanism 4 arranged on the machine table 1 on the front side of the sewing mechanism 2, a rear conveying mechanism 5 arranged on the machine table 1 on the rear side of the sewing mechanism 2, and a grabbing mechanism 6 arranged on one side of the machine table 1 and used for moving the pillow on the front conveying mechanism 4 to the rear conveying mechanism 5. The front conveying mechanism 4, the grabbing mechanism 6 and the rear conveying mechanism 5 cooperate to realize the automatic transmission of the pillow from fixation to unloading after the sealing and flanging is completed.

[0026] The clamping and fixing mechanism 3 is a mechanism for clamping and fixing the sealing part of the pillow, and is also the only mechanism in the pillow sealing and overlocking device that requires manual operation. The clamping and fixing mechanism 3 includes a slide rail 31 mounted on the machine 1, and a mounting base plate 32 is slidably arranged on the slide rail 31, and a left clamping arm 33 and a right clamping arm 34 are arranged on the mounting base plate 32, and a left clamping device 331 is arranged at the lower end of the left clamping arm 33.

After the pillow is fixed left and right by the left clamping arm 33 and the right clamping arm 34, the positioning plate 36 presses the side of the pillow to be sealed under the control of the first telescopic cylinder 7 to prevent the pillow from loosening, and at the same time, the side of the pillow to be sealed is in a flat state.

[0027] The right clamping arm 34 includes a fixing plate 341 fixedly connected to the mounting base plate 32, a first transverse slide rail 37 is arranged on the fixing plate 341, a right clamping arm body 342 is slidably arranged on the first transverse slide rail 37, a right clamping device 343 is arranged at the lower end of the right clamping arm body 342, and a second telescopic cylinder 71 is also arranged transversely on the fixing plate 341, and the telescopic end of the second telescopic cylinder 71 is fixedly connected to the side of the right clamping arm body 342. The right clamping arm 34 can be moved and adjusted in the horizontal direction, which has two advantages: 1. The pillow sealing and overlocking equipment can be applied to pillows of different specifications by adjusting the distance between the left clamping arm 33 and the right clamping arm 34; 2. After the two side corners of the pillow are fixed by the left clamping device 331 and the right clamping device 343, the second telescopic cylinder 71 is moved and adjusted to increase the distance between the right clamping arm body 342 and the left clamping arm 33, so that the pillow can be tightened, so that the side of the pillow to be sealed is in a straightened and flat state.

[0028] As a preferred solution, two groups of the first longitudinal slide rails 35 are provided, and the sliders on the two groups of the first longitudinal slide rails 35 are fixedly connected to the positioning plate 36. Two groups of the first transverse slide rails 37 are provided, and the two groups of the first transverse slide rails 37 are slidably connected to the right clamping arm body 342. Both the first longitudinal slide rail 35 and the first transverse slide rail 37 can adopt a double slide rail structure to make the sliding structure more stable and the sliding adjustment more precise. When necessary, the number of slide rails can be further increased or decreased to achieve better coordination between the various mechanisms.

[0029] A pad 38 is provided below the clamping and fixing mechanism 3, and the two ends of the pad 38 are fixedly connected to the lower end of the left clamping arm 33 and the lower end of the right clamping arm body 342, respectively. The left clamping device 331 includes a left telescopic cylinder 332 and a left lower clamp 333 fixedly connected to the left clamping arm 33, and the telescopic end of the left telescopic cylinder 332 extends downward and is fixedly provided with a left upper clamp 334, and the left lower clamp 333 and the left upper clamp 334 are combined to form a left clamp. The right clamping device 343 includes a right telescopic cylinder 344 and a right lower clamp 345 fixedly connected to the right clamping arm body 342, and the telescopic end of the right telescopic cylinder 344 extends downward and is fixedly provided with a right upper clamp 346, and the right lower clamp 345 and the right upper clamp 346 are combined to form a right clamp. The left upper clamp 334 is controlled by the left telescopic cylinder 332 to move up and down, and the left clamp also clamps and places the side corner of the pillow. Similarly, the right upper clamp 346 is controlled by the right telescopic cylinder 344 to move up and down, and the right clamp also clamps the side corner of the pillow. The pad 38 moves together with the clamping and fixing mechanism 3 during sewing, which can prevent the pillow from directly contacting the table of the machine 1 and ensure the stability of the sealing and overlocking.

[0030] An auxiliary clamping mechanism 8 is arranged on the machine 1 at the rear side of the clamping and fixing mechanism 3. The auxiliary clamping mechanism 8 includes a fixed bottom plate 81 arranged on the machine 1, a third telescopic cylinder 72 is arranged horizontally on the fixed bottom plate 81, a telescopic rod of the third telescopic cylinder 72 faces the clamping and fixing mechanism 3 and is fixedly provided with a vertical mounting plate 82, a fourth telescopic cylinder 73 is arranged longitudinally on the vertical mounting plate 82, a clamping plate 83 is arranged on the telescopic end of the fourth telescopic cylinder 73, and at least two clamping claws 84 are arranged on the clamping plate 83.

When fixing the pillow, the left clamping arm 33 and the right clamping arm 34 are first used to fix the two side corners of the pillow to be sealed, and then the fourth telescopic cylinder 73 is used to control the clamping plate 83 to descend, so that the two clamping claws 84 cooperate with the table of the machine 1 to clamp the middle position of the pillow to be sealed to prevent the pillow from shifting when the positioning plate 36 is pressed down. After the positioning plate 36 presses the side of the pillow to be sealed, the clamping claws 84 of the clamping and fixing mechanism 3 are released, and the clamping and fixing mechanism 3 as a whole can be retracted backward.

[0031] The front conveying mechanism 4 includes a first mounting frame 41 arranged on the machine 1 at the front side of the sewing mechanism 2 and a first belt conveying device 42 mounted on the top of the first mounting frame 41. The first belt conveying device 42 includes a first driving shaft 421 and a first driven shaft 422, which are respectively arranged on both sides of the first mounting frame 41, and the first driving shaft 421 and the first driven shaft 422 are fixedly provided with corresponding pulleys, and a first transmission belt 423 is arranged between the corresponding two pulleys on the first driving shaft 421 and the first driven shaft 422. The first driving shaft 421 is connected to the corresponding motor on the machine 1, and the first driving shaft 421 is driven by the motor to rotate, thereby driving the pulley and the corresponding first transmission belt 423 to rotate. When the pillow sealing and flanging equipment is working, the front conveying mechanism 4 and the clamping and fixing mechanism 3 are synchronously operated. When the clamping and fixing mechanism 3 moves and performs the sealing and flanging work, the front conveying mechanism 4 holds the pillow and moves synchronously.

[0032] As a preferred solution, a limiting mechanism is provided on the first mounting frame 41 below the first belt conveyor 42, and the limiting mechanism includes two telescopic limiting rods 43, and the telescopic limiting rods 43 are provided in the gap between two adjacent first transmission belts 423 and the telescopic limiting rods 43 can be extended to the top of the first belt conveyor 42 to limit the pillow. After the pillow sealing and flanging equipment completes the sealing and flanging of the pillow, the clamping and fixing mechanism 3 will release the side of the pillow and reset. At this time, the telescopic limiting rod 43 extends upward and blocks the right side of the pillow after the sealing is completed, so that the pillow will not be taken away during the resetting movement of the clamping and fixing mechanism 3.

[0033] In addition, a protection frame 9 is provided on the side of the machine 1, and the grabbing mechanism 6 includes a second transverse slide rail 91 provided on the protection frame 9, a second longitudinal slide rail 92 provided on the slider of the second transverse slide rail 91, and a clamping claw 93 provided on the slider of the second longitudinal slide rail 92, and the clamping claw 93 is located higher than the rear conveying mechanism 5 and can move between the front conveying mechanism 4 and the rear conveying mechanism 5. The position of the pillow restricted by the limiting mechanism is located below the initial position of the clamping claw 93 on the grabbing mechanism 6, and the clamping claw 93 can move the pillow from the front conveying mechanism 4 to the rear conveying mechanism 5 as long as the second transverse slide rail 91 and the second longitudinal slide rail 92 are moved.

[0034] The overall structure of the rear conveying mechanism 5 is similar to that of the front conveying mechanism 4, and includes a second mounting frame 51 arranged on the machine 1 at the rear side of the sewing mechanism 2 and a second belt conveyor 52 mounted on the top of the second mounting frame 51. The second belt conveyor 52 includes a second driving shaft 521 and a second driven shaft 522. The second driving shaft 521 is connected to the motor on the machine 1. The second driving shaft 521 and the second driven shaft 522 are respectively arranged on both sides of the second mounting frame 51, and the second driving shaft 521 and the second driven shaft 522 are fixedly provided with corresponding pulleys. A second transmission belt 523 is arranged between the corresponding two pulleys on the second driving shaft 521 and the second driven shaft 522. The installation position of the second belt conveyor 52 is higher than the first belt conveyor 42, and a downwardly inclined unloading plate 55 is fixedly provided on the side of the second mounting frame 51 away from the protective frame 9. After the pillows conveyed by the second belt conveyor 52 arrive at the unloading plate 55, they fall along the unloading plate 55 and are collected, so as to realize the automatic collection of the pillows after the sealing and overlocking is completed.

[0035] In order to improve the safety of the equipment, protective plates 99 are provided on the protective frames 9 on the front, left and rear sides of the machine 1. In order to improve the accuracy and efficiency of pillow fixing, a laser calibration device is also provided on the machine 1. The laser calibration device can be provided on a frame or other mechanism above the laser calibration device, and the laser guide line emitted by the laser calibration device can guide employees to find the accurate pillow fixing position.

[0036] As another preferred solution, a fifth telescopic cylinder 19 is longitudinally arranged on the machine table 1 between the sewing mechanism 2 and the clamping and fixing mechanism 3, and a lifting frame 18 is fixedly arranged at the telescopic end of the fifth telescopic cylinder 19, and a guide 10 is arranged on the lifting frame 18, and the guide 10 includes a vertically arranged front guide plate 11 and an inclined top guide plate 12, the side of the top guide plate 12 close to the sewing mechanism 2 is the low side, and the end of the top guide plate 12 close to the clamping and fixing mechanism 3 is the high side, and there is a gap between the lower edge of the front guide plate 11 and the table surface of the machine table 1 for the pillow sealing to pass through. A transverse guide plate 13 is also arranged on the side of the top guide plate 12 close to the sewing mechanism 2. The inclined top guide plate 12 can gradually flatten the raised part of the side of the pillow to be sealed in the process of the pillow to be sealed moving toward the sewing mechanism 2, and finally press the side of the pillow to be sealed to a flat state through the transverse guide plate 13, so that the subsequent sealing and overlocking of the sewing mechanism 2 is accurate and stable.

[0037] In the pillow sealing and overlocking device, the telescopic cylinder can be an electric telescopic cylinder or a pneumatic cylinder, the slide rail is an electric slide rail, and the sewing mechanism 2 is an existing sewing device with an overlocking function. In addition, the coordinated work between the mechanisms is realized by the control of the main control device of the device.

[0038] Working principle: The operator first fixes the two corners of the side of the pillow to be sealed through the left clamping arm 33 and the right clamping arm 34. The right clamping arm 34 will move a certain distance to the right while fixing, so that the side of the pillow is in a taut and flat state. Then, the operator controls the two clamping claws 84 on the auxiliary clamping mechanism 8 to cooperate with the table of the machine 1 to clamp the middle position of the pillow to be sealed. After that, after the positioning plate 36 on the clamping and fixing mechanism 3 presses the side of the pillow to be sealed, the clamping claws 84 of the clamping and fixing mechanism 3 are released and reset. Then, the slide rail 31 of the clamping and fixing mechanism 3 cooperates with the front conveying mechanism 4 to move the pillow to the sewing mechanism 2, and maintains the moving state to complete the sealing and overlocking. After the pillow is sealed and hemmed, it is located at the end of the front conveying mechanism 4, that is, the left side of the front conveying mechanism 4. At this time, the telescopic limit rod 43 of the limit mechanism extends upward to block the right side of the pillow. Then the left clamping arm 33 and the right clamping arm 34 of the clamping and fixing mechanism 3 release the pillow, and the whole moves and resets under the drive of the slide rail 31. Finally, the pillow after sealing and hemming is grasped by the grasping mechanism 6 to the rear conveying mechanism 5, and then falls from the unloading plate 55 under the conveyance of the rear conveying mechanism 5 and is collected.
