[0020] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0021] like Figure 1-Figure 3The illustrated clamping and fixing mechanism of a sealing sewing machine includes a worktable 1 and a vertical mounting plate 11 disposed above the worktable 1. The vertical mounting plate 11 is not fixed to the worktable 1 and is subsequently connected to a conveying mechanism to enable the movement and conveyance of the clamped and fixed pillows. Two sets of clamping assemblies 2 are disposed on the vertical mounting plate 11, which are used to clamp and fix the two sides of the pillow to be sealed. A pressure plate assembly 3 is disposed on the vertical mounting plate 11 between the two sets of clamping assemblies 2. The pressure plate assembly 3 cooperates with the clamping assembly 2 to flatten the sides of the pillow to be sealed, facilitating subsequent sewing and sealing on the conveyor.

[0022] The clamping assembly 2 includes a transverse slide rail 21 provided 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 provided 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 provided 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. The upper clamping plate 5 and the lower clamping plate 51 correspond to each other to form a clamp for clamping and fixing the side of the pillow. Both the upper clamping plate 5 and the lower clamping plate 51 are detachable, which is convenient for replacing different types of clamps. The upper clamping plate 5 includes an integrally formed first fixing portion 53 and a first clamping portion 54. The first fixing portion 53 is fixedly connected to the second movable mounting plate 41. The lower clamping plate 51 includes an integrally formed second fixing portion 55 and a second clamping portion 56. 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 port. Preferably, anti-slip portions are provided on the opposite sides of the first clamping portion 54 and the second clamping portion 56. The anti-slip portions may be anti-slip pads, or anti-slip grooves or anti-slip particles directly provided on the clamping portions. 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 and improving the sealing efficiency.

[0023] 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. A second telescopic cylinder 61 is provided on the vertical mounting plate 11 on one side of the transverse slide rail 21. The end of the telescopic rod of the second telescopic cylinder 61 is fixedly connected to the adjacent first movable mounting plate 4 and drives the first movable mounting plate 4 to move horizontally. Fixed frames 8 are provided on both sides of the vertical mounting plate 11. The second telescopic cylinder 61 is fixedly connected to the adjacent fixed frame 8. The setting of the fixed frame 8 facilitates the installation of the second telescopic cylinder 61. The main function of the first telescopic cylinder 6 is to control the upper clamping plate 5 to move up and down, and cooperate with the lower clamping plate 51 to clamp and fix the pillow to be sealed. The main function of the second telescopic cylinder 61 is to control the left and right movement of the first movable mounting plate 4, and further tighten the side of the clamped and fixed pillow for better subsequent sealing.

[0024] The pressure plate assembly 3 comprises a connecting base plate 31 fixedly connected to the vertical mounting plate 11, a mounting plate 32 mounted on the connecting base plate 31, and a pressure plate 33. The pressure plate 33 is provided with a sewing opening 34, and the connecting base plate 31 is positioned between the pressure plate 33 and the vertical mounting plate 11. The sewing opening 34 is where the sewing machine performs the sewing and sealing operation, so the position of the sewing opening 34 must correspond to the positions of the clamping openings on either side. The mounting plate 32 and pressure plate 33 are connected by a first rotating connector 35, allowing for relative rotation. This first rotating connector 35 can be a hinge or a rotating shaft, ensuring stable rotation of the mounting plate 32 and pressure plate 33. A third telescopic cylinder 62 is mounted on the mounting plate 32, and a connecting block 36 is mounted on the pressure plate 33. The end of the telescopic rod of the third telescopic cylinder 62 is rotatably connected to the connecting block 36 via a second rotating connector 37. The telescopic rod of the third telescopic cylinder 62 is extended and retracted to control the rotation of the pressure plate 33.

[0025] The first, second, and third telescopic cylinders 6, 61, 62 can be electric or pneumatic, facilitating automated control. The second rotating connector 37 is a spherical bearing mounted at the end of the telescopic rod of the third telescopic cylinder 62. The connecting block 36 is connected to the spherical bearing via a connecting shaft. The spherical bearing rotates relative to the connecting shaft, thereby driving the pressure plate 33 to rotate upward to open or downward to compress during the telescopic rod extension and retraction of the third telescopic cylinder 62.

[0026] As a preferred solution, two third telescopic cylinders 62 are provided on the mounting plate 32. When in use, the two third telescopic cylinders 62 are controlled to work synchronously at the same time, which can make the rotation structure of the pressure plate 33 more stable and the opening and pressing force greater. A rotating mounting seat 7 is provided 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 to a certain angle when required, making the rotation control of the pressure plate 33 smoother. A reinforcement plate 71 is fixedly connected to one side of the rotating mounting seat 7, and the reinforcement plate 71 is fixedly connected to the mounting plate 32. The reinforcement plate 71 can improve the installation firmness of the rotating mounting seat 7 and the third telescopic cylinder 62.

[0027] Working Principle: The operator first inserts the two ends of the side of the pillow to be sealed into the clamping opening and places them close to the inner wall at the deepest part of the clamping opening. Then, the upper and lower clamping plates 5 and 51 are controlled to clamp. Next, the second telescopic cylinder 61 controls the clamping assembly 2 to move outward a certain distance, that is, the two sets of clamping assemblies 2 move in opposite directions. During the reverse movement of the two sets of clamping assemblies 2, the sides of the sealed pillow are properly tightened and not easily loosened. Finally, the third telescopic cylinder 62 on the pressing plate assembly 3 controls the pressing plate 33 to press down, flattening the area to be sealed. This completes the clamping and fixing of the pillow before sewing. The overall process is simple to operate and the fixing position is precise.

[0028] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
