Description

Technical Field

[0001] The present invention relates to the technical field of sewing equipment, and particularly relates to a sealing sewing machine. Background Art

[0002] In the production of pillows, sealing sewing is the last and very crucial step. In current pillow production factories, pillows are generally sewn and sealed manually, which requires the employees performing the sealing sewing to be proficient in operation. Otherwise, the sewing thread will be bent, affecting the quality of the pillows. However, there are also many problems with manual sewing and sealing. The two most important ones are: 1. The efficiency of manual sewing and sealing is low. 2. There are few employees who can operate proficiently, and the training cost is high.

[0003] To solve the above problems, pillow manufacturers hope to design a sealing sewing device to reduce the requirement for employee proficiency and improve the sewing efficiency. Currently, there is no sealing sewing device with a particularly high degree of automation on the market. Manual operations are still required in many sewing steps, which means that the operating employees still need to be familiar with multiple operating links. Moreover, the operating efficiency of multiple steps such as pillow fixation and sewing still depends on the proficiency of the employees, which is not very helpful for improving the sewing and sealing efficiency and reducing the dependence on employees.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0026] Such as Figures 1-8A sealing sewing machine shown in the figure includes a machine table 111 with a workbench plate 1 arranged at the top, a sewing device 112 arranged on the workbench plate 1, an electric slide rail 113 arranged above the machine table 111 and below the sewing device 112, a clamping and fixing mechanism arranged on the electric slide rail 113 and capable of being conveyed to the lower part of the sewing device 112 through the electric slide rail 113, and a lifting and conveying mechanism 81 arranged on one side of the machine table 111. 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 towards the sewing device 112 together. At this time, the lifting and conveying mechanism 81 supports 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 the electric slide rail 113. Two clamping assemblies 2 are arranged on the vertical mounting plate 11. A pressing plate assembly 3 is arranged on the vertical mounting plate 11 between the two clamping assemblies 2. The pressing plate assembly 3 cooperates with the clamping assemblies 2 to flatten the side of the pillow to be sealed. The clamping assembly 2 includes a horizontal slide rail 21 arranged on the vertical mounting plate 11, a first movable mounting plate 4 slidably connected to the horizontal 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. A lower clamping plate 51 close to the workbench plate 1 is arranged on the first movable mounting plate 4. The upper clamping plate 5 and the lower clamping plate 51 form a fixture corresponding to each other up and down. The upper clamping plate 5 includes an integrally formed first fixing part 53 and a first clamping part 54. The first fixing part 53 is fixedly connected to the second movable mounting plate 41. The lower clamping plate 51 includes an integrally formed second fixing part 55 and a second clamping part 56. The second fixing part 55 is fixedly connected to the first movable mounting plate 4. The corresponding first clamping part 54 and second clamping part 56 form a positioning clamping opening. Preferably, anti-slip parts are arranged on the opposite sides of the first clamping part 54 and the second clamping part 56. The anti-slip parts can be anti-slip pads, or anti-slip grooves or anti-slip particles directly opened on the clamping parts. The opening of the clamping opening faces forward. The depths of the clamping openings extending inwards on the two clamping assemblies 2 are the same, and this depth is determined according to the sewing position of the side of the pillow to be sealed. The operator only needs to respectively extend the two ends of the side of the pillow to be sealed into the clamping opening and close to the inner wall of the deepest part 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 fixing position of the pillow is accurate, thereby reducing the requirement for the operator's proficiency.

[0028] On one side of the first movable mounting plate 4, a first telescopic cylinder 6 is provided. 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. On the vertical mounting plate 11 on one side of the horizontal slide rail 21, a second telescopic cylinder 61 is provided. 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 up and down movement of the upper clamping plate 5 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 pillow for better subsequent sealing.

[0029] As another preferred solution, the pressing plate assembly 3 includes a connecting bottom plate 31 fixedly connected to the vertical mounting plate 11, a mounting plate 32 provided on the connecting bottom plate 31, and a pressing plate 33. A sewing opening 34 is provided on the pressing plate 33 and the connecting bottom plate 31 is arranged between the pressing plate 33 and the vertical mounting plate 11. The sewing opening 34 is the position where the sewing machine sews and seals. Therefore, the position of the sewing opening 34 needs to correspond to the positions of the two clamping openings. The mounting plate 32 and the pressing plate 33 are connected by a first rotating connector 35 and can rotate relative to each other. The first rotating connector 35 can be a hinge or a rotating shaft structure as long as the mounting plate 32 and the pressing plate 33 can rotate stably.

[0030] A third telescopic cylinder 62 is provided on the mounting plate 32, a connecting block 36 is provided on the pressing plate 33, and the end of the telescopic rod of the third telescopic cylinder 62 is rotatably connected to the connecting block 36 through a second rotating connector 37. The rotation of the pressing plate 33 is controlled by the telescopic movement of 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 adopt electric telescopic cylinders or pneumatic telescopic cylinders, which are convenient for automatic control. The second rotating connector 37 is a spherical plain bearing provided at the end of the telescopic rod of the third telescopic cylinder 62, and the connecting block 36 is connected to the spherical plain bearing through a connecting shaft. The spherical plain bearing can rotate relative to the connecting shaft, so that during the telescopic movement of the telescopic rod of the third telescopic cylinder 62, the pressing plate 33 is driven to rotate upward to open or rotate downward to press.

[0031] In addition, two third telescopic cylinders 62 can be arranged on the mounting plate 32. When in use, controlling the two third telescopic cylinders 62 to work synchronously can make the rotation structure of the pressing plate 33 more stable and the opening and pressing-down forces greater. A rotating mounting seat 7 is arranged on the mounting plate 32. 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 that of the pressing plate 33. The design of the rotating mounting seat 7 enables the third telescopic cylinder 62 to rotate at a certain angle when work requires, making the rotation control of the pressing plate 33 smoother. A reinforcing plate can be fixedly arranged on one side of the rotating mounting seat 7, and the reinforcing plate can improve the mounting 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 table 111, a belt conveying device 83 erected on the top of the mounting bracket 82, and a protective baffle 88 and a guiding baffle 89 respectively arranged on both sides of the mounting bracket 82. The belt conveying device 83 includes a first driving shaft 831 and a first driven shaft 832. The first driving shaft 831 and the first driven shaft 832 are respectively arranged on both sides of the mounting bracket 82, and corresponding belt pulleys are fixedly arranged on both the first driving shaft 831 and the first driven shaft 832. A transmission belt 833 is arranged between the two corresponding belt pulleys on the first driving shaft 831 and the first driven shaft 832.

[0033] Four belt pulleys can be arranged on each of the first driving shaft 831 and the first driven shaft 832. A transmission belt 833 is arranged between the two corresponding belt pulleys on the first driving shaft 831 and the first driven shaft 832, that is, multiple transmission belts 833 are arranged in parallel. Compared with an integral transmission belt, less material is used. Both the first driving shaft 831 and the first driven shaft 832 are rotatably mounted on the mounting bracket 82 through mounting seats. 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 arranged on the side surface of the machine table 111. A reinforcing frame 911 is arranged on the machine table 111 between the first driving shaft 831 and the first driving motor 9. The first driving shaft 831 passes through the reinforcing 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 a top baffle 881 and a first side baffle 882 formed integrally. The top baffle 881 is arranged horizontally, and the first side baffle 882 is arranged vertically. The protective baffle 88 can prevent the operator from touching the side of the conveying device, improving the operation safety. The guiding baffle 89 includes a guiding plate 891 and a second side baffle 892 formed integrally. The second side baffle 892 is arranged vertically. The guiding plate 891 is inclined towards the belt conveying device 83, and the highest point of the guiding plate 891 is lower than the conveying plane of the belt conveying device 83. The guiding plate 891 has two functions. One is the same as that of the protective baffle 88, preventing the operator from touching the side of the conveying device. The other is that when the pillow moves to the guiding baffle 89, the controller controls the clamping and fixing mechanism to release the sealed side of the pillow, and the pillow will slide forward under the guidance of the guiding plate 891, realizing automatic blanking.

[0035] Inside the machine table 111, there are arranged a second driving shaft 921, two second driven shafts 922 respectively connected to the second driving shaft 921 by belts, and sliding mechanisms 94 arranged on one side corresponding to the two second driven shafts 922 one by one. The sliding mechanism 94 includes a sliding track 942 and a sliding bracket 941 slidably connected to the sliding track 942. A connecting clamping plate 943 is arranged on the side of the sliding bracket 941, and the connecting clamping plate 943 is fixedly connected to the adjacent belt so that the belt can drive the sliding bracket 941 to move. Inside the machine table 111, there are arranged 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. Generally, there are two driving shaft mounting seats 101, which are respectively arranged at both ends of the second driving shaft 921. Additionally, a reinforcing seat can be arranged between the two driving shaft mounting seats 101 to improve the mounting stability of the second driving shaft 921. The two second driven shafts 922 can be respectively connected to the second driving shaft 921 by belts and rotate synchronously driven by the second driving shaft 921, or a rotating shaft can be further connected between the two second driven shafts 922 to further ensure the consistency of the rotation of the two second driven shafts 922. A second driving motor 99 is arranged 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 disposed on the top of the sliding base 98. A fixing plate 983 for the electric slide rail 113 is provided on the front side of the top of the fixed bracket 982. On the top of the sliding base 98, a first mounting plane 984, a second mounting plane 985, and a third mounting plane 986 are arranged from high to low. Mounting holes are installed on the first mounting plane 984, the second mounting plane 985, and the third mounting plane 986. The fixed bracket 982 is installed on the first mounting plane 984 or the second mounting plane 985, and the connecting clamping plate 943 is detachably installed on the third mounting plane 986. The fixed bracket 982 and the electric slide rail 113 can have different installation positions for adjustment, and multiple groups of mounting holes can also be provided to adjust the front and back positions of the installation. A toothed groove is provided on the bottom surface of the connecting clamping plate 943, and the corresponding belt is fixed between the connecting clamping plate 943 and the sliding base 98. The design of the toothed groove can increase the connection firmness between the belt and the connecting clamping plate 943 and effectively prevent loosening. In addition, through grooves for the front and back sliding of the sliding brackets 941 are provided at the positions corresponding to the two sliding brackets 941 on the workbench plate 1, so that the sliding brackets 941 can smoothly drive the electric slide rail 113 to achieve front and back adjustment.

[0037] Working principle: During operation, the operator first inserts the two ends of the side of the pillow to be sealed into the clamping openings of the clamping and fixing mechanism and approaches the inner wall of the deepest part of the clamping opening. Then, the upper clamping plate and the lower clamping plate are controlled to clamp. Next, the second telescopic cylinder controls the clamping assembly to move outward a certain distance, that is, the two clamping assemblies move in opposite directions. During the opposite movement of the two clamping assemblies, the side of the pillow to be sealed is properly tightened and not easily loosened. Then, the third telescopic cylinder on the pressing plate assembly controls the pressing plate to press down, flattening the part of the pillow to be sealed. In this way, the clamping and fixing before sewing and sealing of the pillow are completed. The next step is that the controller controls the second driving motor to work, moves the electric slide rail to a position matching the sewing equipment, and then controls the synchronous movement of the electric slide rail and the lifting and conveying mechanism to move the pillow to be sealed towards the sewing equipment. When the pillow moves below the sewing equipment, the sewing 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 sewing is completed. After the sewing is completed, the pillow continues to move forward under the drive of the electric slide rail and the lifting and conveying mechanism until it reaches the guiding baffle, and then the two clamping assemblies on the clamping and fixing mechanism are loosened. The sealed pillow falls under the guidance of the guiding baffle for collection. Finally, the controller controls the electric slide rail and other components to reset for sewing and sealing the next pillow.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
