DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 4As shown, a steel carcass cord sewing machine according to an embodiment of the utility model comprises an aluminum alloy bracket 15; a switch assembly is installed in the middle of the aluminum alloy bracket 15; a driving motor 12 is installed in the middle of the aluminum alloy bracket 15; a forward / reverse switch 4 is installed at the bottom of the driving motor 12; an active bevel gear 7 is installed at the output end of the driving motor 12; a connecting support 14 is installed at the top of the aluminum alloy bracket 15; a pressing wheel 8 is installed on one side of the connecting support 14; the active bevel gear 7 is installed on the other side of the connecting support 14 On one side; the bottom of the aluminum alloy bracket 15 is installed with an articulated seat 13; the middle of the articulated seat 13 is rotatably connected with a pressing bracket 10; the middle of the pressing bracket 10 is installed with a pressing bottom roller 9; the middle of the aluminum alloy bracket 15 is installed with an adjusting sleeve 16; the top of the adjusting sleeve 16 is installed with an adjusting nut 6; the top of the adjusting sleeve 16 is installed with a disc spring push rod 5; the bottom of the adjusting sleeve 16 is installed with an adjusting screw 11; the end of the pressing bracket 10 is located inside the adjusting sleeve 16, and when working, the pressing bracket 10 is adjusted by adjusting the pressing nut 6; the top of the adjusting sleeve 16 is installed with a disc spring push rod 5; the bottom of the adjusting sleeve 16 is installed with an adjusting screw 11; the end of the pressing bracket 10 is located inside the adjusting sleeve 16, and when working, the pressing nut The ends of the cord are placed on the pressing bracket 10, so that the end is between the pressing bottom roller 9 and the pressing wheel 8, and then the working state is realized by turning on the switch, so that the power source drives the driving motor 12, and the driving bevel gear 7 is driven to rotate under the drive of the driving motor 12, so that the driving bevel gear 7 drives the pressing wheel 8 to rotate, and then the cord between the pressing wheel 8 and the pressing bottom roller 9 is pressed. When it is necessary to sew cords of different sizes, the cord splicing pressure is controlled by the adjusting sleeve 16, and the adjusting nut 6 is rotated to adjust the cord. The angle of the end of the pressing bracket 10 inside the adjusting sleeve 16 is adjusted, thereby expanding or reducing the space gap between the pressing bracket 10 and the pressing wheel 8, thereby increasing or decreasing the placement space of the curtain, adjusting the pressure on the curtain during splicing, and enabling the device to sew curtains of different thicknesses, thereby increasing the adaptability of the device. When the curtain between the pressing wheel 8 and the pressing bottom roller 9 is abnormally pressed, the pressing wheel 8 can be withdrawn by rotating the forward / reverse switch 4 in the reverse direction, thereby taking out the curtain and reducing the occurrence of accidents.

[0023] like Figures 1 to 4 As shown, the pressed bracket 10 and the aluminum alloy bracket 15 are inclined; the inclination angle between the pressed bracket 10 and the aluminum alloy bracket 15 is 9 degrees.

[0024] like Figures 1 to 4 As shown, the laminating bottom roller 9 is provided with a pair of symmetrically arranged threads, and the angle of the threads is set at 120 degrees. When working, the contact between the cord and the laminating bottom roller 9 can be further improved by laminating bottom roller 9, so as to achieve the effect of splicing in synchronization with the laminating wheel 8, and the force between the laminating bottom roller 9 and the laminating wheel 8 is further increased, so that the upper and lower surfaces of the tire carcass are firmly joined, thereby achieving the characteristics of uniform indentation, non-deformation of the steel wire, and firm and beautiful splicing marks.

[0025] like Figures 1 to 4 As shown, the switch assembly includes a handle 3; the handle 3 is arranged in the middle of the aluminum alloy bracket 15; a start switch 2 is installed in the middle of the handle 3; a switch pressing handle 1 is installed in the middle of the handle 3; the switch pressing handle 1 is arranged obliquely above the start switch 2. When working, by setting the switch into a structure of the handle 3, the start switch 2 and the switch pressing handle 1, when the switch needs to be pressed, only one finger is needed to slide from top to bottom on the surface of the switch pressing handle 1, thereby pressing the start switch 2 to turn on the switch, which is more convenient and quick, and reduces the tedious process of finding the switch button.

[0026] like Figures 1 to 4 As shown, the drive motor 12 is set as a DC reduction motor. When working, by setting the drive motor 12 as a DC reduction motor, it has a better control effect, is less likely to cause accidents, and improves the safety and stability during work.

[0027] During operation, the ends of the cords to be pressed are placed on the pressing bracket 10 so that the port is between the pressing bottom roller 9 and the pressing wheel 8. Then, the switch is turned on to realize the working state, so that the power source drives the driving motor 12. The driving motor 12 drives the active bevel gear 7 to rotate, so that the active bevel gear 7 drives the pressing wheel 8 to rotate, and then the cords between the pressing wheel 8 and the pressing bottom roller 9 are pressed. When cords of different sizes need to be sewn, the cord splicing pressure is controlled by the adjusting sleeve 16. By rotating the adjusting nut 6, the angle of the end of the pressing bracket 10 inside the adjusting sleeve 16 is adjusted, so that the space gap between the pressing bracket 10 and the pressing wheel 8 is expanded or reduced, and then the placement space of the cord is adjusted to increase or decrease, and the cord is adjusted to be subjected to the splicing pressure. The pressure is increased, so that the device can sew cords of different thicknesses, which increases the adaptability of the device. When the cord between the pressing wheel 8 and the pressing bottom roller 9 is pressed abnormally, the pressing wheel 8 can be withdrawn by rotating the reversing switch 4 in the opposite direction, and the cord can be taken out to reduce the occurrence of accidents. The contact between the cord and the pressing bottom roller 9 can be further improved by the pressing bottom roller 9, so that the effect of splicing with the pressing wheel 8 can be achieved, and the force between the pressing bottom roller 9 and the pressing wheel 8 is further increased, so that the upper and lower surfaces of the tire carcass are firmly joined. By setting the switch to a structure of a handle 3, a start switch 2 and a switch pressure handle 1, when the switch needs to be pressed, only one finger is needed to slide from top to bottom on the surface of the switch pressure handle 1, so as to press the start switch 2 and turn on the switch, which is more convenient and quick.
