DETAILED DESCRIPTION

[0022] The utility model discloses a kind of mobile rotary feeding devices of automatic overlock machine, as Figure 1 And Figure 2As shown, the feeding device 1 is arranged on the workbench 13 of the automatic overlock machine 12, comprising support frames 131 and support columns 132 fixedly connected to the left and right sides of the workbench 13 respectively, the support frames 131 are linearly distributed in the X-axis direction of the workbench 13 and the top is provided with a transmission assembly, the output end of the transmission assembly is connected with two first synchronous belt modules 3 linearly distributed in the Y-axis direction of the workbench 13, the end of the first synchronous belt module 3 away from the transmission assembly is connected above the support column 132, the output end of the two first synchronous belt modules 3 is connected to a connecting plate 4, the surface of the connecting plate 4 is provided with a second synchronous belt module 5 linearly distributed in the X-axis direction of the workbench 13, the output end of the second synchronous belt module 5 is connected with a sliding assembly 6, the sliding assembly 6 is connected with a third synchronous belt module 7 moving in the X-axis direction of the workbench 13, the output end of the third synchronous belt module 7 is connected with a pressing assembly 9.

[0023] It should be noted that the transmission assembly driving two first synchronous belt modules 3 linearly distributed in the Y-axis direction of the workbench 13, the Y-axis is composed of two synchronous belt modules and a support column 132 in a gantry structure, so that two second synchronous belt modules 5 in the X-axis direction of the workbench 13 move in the Y-axis direction of the workbench 13, and two second synchronous belt modules 5 and third synchronous belt modules 7 linearly distributed in the X-axis direction of the workbench 13 form an extensible structure, thereby forming a driving structure with a large moving range, and the working end of the pressing assembly 9 can complete the conveying action in a large range, and the working end of the pressing assembly 9 is directly driven by a motor, which is simple in structure, high in precision, and the motors on the synchronous belt modules are matched with the synchronous action, which is accurate and efficient.

[0024] It should be further noted that, as shown in Figure 2 and Figure 3 , the transmission assembly comprises a first motor 21 and a connecting shaft 22, the first motor 21 is fixedly connected to the surface of the support frame 131, the surface of the support frame 131 outside the first motor 21 is provided with a matching seat 23, the input ends of the two first synchronous belt modules 3 are located at the front and rear ends of the matching seat 23 respectively, the connecting shaft 22 is matched in the matching seat 23 and connected with the input ends of the first synchronous belt modules 3, one of the axial ends of the connecting shaft 22 penetrates out of the matching seat 23 and is connected with the output end of the first motor 21.

[0025] The first motor 21 drives the connecting shaft 22 to rotate, thereby driving the two first synchronous belt modules 3 to work, driving the output ends of the two first synchronous belt modules 3 to move in the Y-axis direction of the workbench 13, driving the connecting plate 4 to move in the Y-axis direction of the workbench 13, and further driving the second synchronous belt module 5 and the third synchronous belt module 7 to move in the Y-axis direction of the workbench 13. The first synchronous belt module 3 is arranged transversely on the left and right sides of the workbench 13, so that the second synchronous belt module 5 and the third synchronous belt module 7 can move in a large range in the Y-axis direction of the workbench 13.

[0026] It should be further explained that, as Figure 4 and Figure 5 As shown in combination, the sliding assembly 6 comprises a first sliding rail 61, a matching block 62 and a connecting block 63. The middle part of the connecting plate 4 is provided with a strip-shaped through hole 41. The first sliding rail 61 is arranged on the top of the third synchronous belt module 7. The bottom end of the connecting plate 4 is provided with at least two matching blocks 62. The matching blocks 62 are matched with the top of the first sliding rail 61. The output end of the second synchronous belt module 5 is connected with the connecting block 63 which extends below the through hole 41 and is fixedly connected with the side wall of the third synchronous belt module 7.

[0027] When the second synchronous belt module 5 works, the connecting block 63 drives the entire third synchronous belt module 7 to move in the Y-axis direction of the workbench 13 below the position. The matching between the matching block 62 and the first sliding rail 61 makes the third synchronous belt module 7 more straight when sliding, thereby moving linearly in the X-axis direction of the workbench 13.

[0028] Specifically, as Figure 4 and Figure 6 As shown in combination, the top surface of the third synchronous belt module 7 outside the first sliding rail 61 is provided with a first proximity switch 8.

[0029] The first proximity switch 8 behind the first sliding rail 61 can sense the position of the matching block 62 behind the second synchronous belt module 5, thereby avoiding the overstroke of the third synchronous belt module 7 when moving below the second synchronous belt module 5, and preventing the collision between the driving source on the third synchronous belt module 7 and the matching block 62.

[0030] Specifically, as Figure 5 shown, the surface of the connecting plate 4 on the front and rear sides of the through hole 41 is provided with a second proximity switch 10.

[0031] The second proximity switch 10 can detect the distance between the output end of the second synchronous belt module 5, and the control of the second synchronous belt module 5 is performed according to the distance information fed back by the second proximity switch 10, thereby preventing the connecting block 63 from colliding with the wall surface of the connecting plate 4 outside the through hole 41.

[0032] It should be further explained that, as Figure 6 and Figure 7 As shown, the material pressing assembly 9 includes a cylinder 91, a second sliding rail 92, a sliding block 93, a sliding seat 94, a second motor 95, and a pressing plate 96. The output end of the third synchronous belt module 7 is connected with a fixed plate 97. The cylinder 91 is fixedly connected to the surface of the middle part of the fixed plate 97. The surfaces of the front and rear sides of the fixed plate 97 are provided with the second sliding rail 92. The sliding block 93 is matched on the second sliding rail 92 and is fixedly connected with one end of the sliding seat 94. The output end of the cylinder 91 is fixedly connected with the top end of the sliding seat 94. The second motor 95 is fixedly connected to the end face of the sliding seat 94 away from the cylinder 91. The pressing plate 96 is fixedly connected to the output end of the second motor 95 and is located below the second motor 95.

[0033] The output end of the third synchronous belt module 7 drives the material pressing assembly 9 to move in the X-axis direction of the workbench 13. Then, the sliding seat 94 is driven by the cylinder 91 to move up and down on the second sliding rail 92, so as to realize the lifting of the pressing plate 96 away from the surface of the cutting piece or the pressing of the pressing plate 96 on the surface of the cutting piece. After the pressing plate 96 is pressed on the surface of the cutting piece, the second motor 95 is driven to work to drive the pressing plate 96 to rotate, so as to adjust the position of the cutting piece on the surface of the workbench 13 below the pressing plate 96. Finally, the cutting piece after the position adjustment is moved to the processing end of the automatic overlock machine 12 for processing. The setting of the pressing plate 96 can make the position of the cutting piece more stable during the processing and prevent the position of the cutting piece from deviating.

[0034] Specifically, as Figure 7 shown, the fixed plate 97 between the cylinder 91 and the second sliding rail 92 is provided with a first fixed seat 98. The wall surface of the sliding seat 94 close to the cylinder 91 is provided with a second fixed seat 99. The first fixed seat 98 and the second fixed seat 99 are connected with a spring 910.

[0035] When the cylinder 91 drives the sliding seat 94 to move, the sliding seat 94 moves quickly on the second sliding rail 92. The spring 910 limits the descending sliding seat 94 at the stretching limit, prevents the overstroke phenomenon of the sliding seat 94 on the second sliding rail 92, and makes the movement of the sliding seat 94 on the second sliding rail 92 more stable.

[0036] It should be further explained that, asFigure 3 As shown, the wall surface near the first synchronous belt module 3 on the side of the connecting plate 4 is provided with a plurality of third proximity switches 11.

[0037] The third proximity switch 11 can detect the distance between it and the connecting plate 4, thereby controlling the distance between the left and right sides of the connecting plate 4 to the support frame 131 and the support column 132. According to the distance information fed back by the plurality of third proximity switches 11, the first synchronous belt module 3 and the second synchronous belt module 5 are controlled, which not only prevents the connecting plate 4 from colliding with the support frame 131, but also prevents the second synchronous belt module 5 from colliding with the support column 132.

[0038] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
