[0008] In a preferred embodiment, a connecting plate is fixedly installed in each of the two brackets near the bottom of the feeding rack, and a guide plate is fixedly installed on the top of the connecting plate to guide the movement of the shoulder strap, so that the shoulder strap accurately enters the conveying area between the upper and lower electric rollers, preventing deviation, and can also be used in conjunction with a belt conveyor for material feeding.

[0009] In a preferred embodiment, the rear walls of both feeding racks are provided with limiting grooves, and each support can be detachably connected to a limiting block at its front end. The limiting block is located in the limiting groove and can guide and limit the lifting process of the support, preventing the support from shifting during lifting and ensuring that the upper and lower electric rollers can be accurately aligned, thus ensuring the stability of the belt conveyor.

[0010] In a preferred embodiment, the conveying mechanism includes a support frame, which is detachably installed on the top of the processing table. Belt conveyors are fixedly installed inside both support frames. The belt conveyors on both sides respectively realize the feeding and unloading of the back belt. It connects smoothly with the feeding mechanism and the riveting mechanism without manual intervention, effectively improving the degree of automation in processing, reducing the labor intensity of operators, and improving processing efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Refer to the instruction manual appendix Figures 1-9 This invention provides a strap rivet riveting device, including a processing table 1. A support base 2 is fixedly mounted on the top of the processing table 1. A riveting mechanism 3 is mounted on the support base 2 for riveting and fixing strap rivets. The riveting mechanism 3 includes a hydraulic cylinder 31, which is detachably fixed to the top of the support base 2. A riveting head 32 is fixedly mounted at the bottom end of the piston rod of the hydraulic cylinder 31. A stamping die 33 is mounted below the riveting head 32 and is detachably mounted on the top of the processing table 1. The hydraulic cylinder 31 is connected to a hydraulic system, which provides stable hydraulic oil to improve the operational stability of the hydraulic cylinder 31. The hydraulic cylinder 31 provides sufficient riveting pressure, driving the riveting head 32 to move downwards and cooperate with the stamping die 33 to achieve riveting and fixing of the rivet. The riveting pressure is stable, ensuring the riveting quality.

[0020] like Figures 1-4 and Figure 6As shown, the top of the processing table 1 is provided with a slide groove 4, and a slider 5 is provided inside the slide groove 4. The top of the slider 5 and the top of the processing table 1 are detachably equipped with a feeding mechanism 6. The feeding mechanism 6 includes a feeding frame 61. The rear ends of the two feeding frames 61 are provided with two supports 62 that are symmetrically distributed vertically. Each support 62 has an electric roller 63 rotatably installed inside. The two electric rollers 63 cooperate to convey the belt. The top and bottom of the feeding frame 61 are fixedly penetrated by a first electric push rod 64. The piston rod of the first electric push rod 64 is fixed to the support 62 to drive the support 62 to rise and fall.

[0021] like Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, conveying mechanisms 7 can be detachably installed on both sides of the top of the processing table 1 to realize the loading and unloading of the shoulder straps. The conveying mechanism 7 includes a support frame 71, which is detachably installed on the top of the processing table 1. A belt conveyor 72 is fixedly installed inside both support frames 71 to transport the shoulder straps without manual intervention, thereby improving the degree of automation in the processing.

[0022] The bottom of the processing table 1 is fixedly provided with a support plate 8, and the top of the support plate 8 is fixedly provided with a linear module 9. The top of the slide of the linear module 9 is detachably connected to the slider 5. Driven by the linear module 9, the slider 5 can be driven to slide left and right along the slide groove 4, thereby driving the feeding rack 61 on the top of the slider 5 to move left and right without manual adjustment, further improving the riveting efficiency.

[0023] Two connecting plates 65 are fixedly installed in the two brackets 62 near the bottom of the feeding rack 61. A guide plate 66 is fixedly installed on the top of the connecting plate 65. The guide plate 66 can limit and guide the strap during the conveying process, prevent the strap from shifting or wrinkling, and ensure that the strap can be accurately conveyed to the riveting mechanism 3, thereby improving the riveting processing accuracy.

[0024] like Figures 1-5 As shown, the support base 2 has a storage groove 34 at its front end, and a second electric push rod 35 is detachably installed on the top of the processing table 1. The piston rod of the second electric push rod 35 passes through the storage groove 34 and is fixed to the rear end of the stamping die 33, which is used to drive the stamping die 33 to move back and forth. A limiting rod 12 is fixedly provided at the rear end of the stamping die 33, and a limiting hole 13 adapted to the limiting rod 12 is provided at the front end of the support base 2. The rear end of the limiting rod 12 passes through the limiting hole 13 and extends out of the outside of the support base 2. Through the extension and retraction of the second electric push rod 35, the stamping die 33 can be driven to move back and forth, and the relative position of the stamping die 33 and the riveting head 32 can be flexibly adjusted, making the operation convenient and improving the processing efficiency.

[0025] like Figure 5 As shown, the limiting rod 12 and the limiting hole 13 slide together, which can guide and limit the forward and backward movement of the stamping die 33, prevent the stamping die 33 from deviating when it moves, ensure that the riveting head 32 and the stamping die 33 can be accurately aligned, and further improve the riveting processing accuracy.

[0026] In this invention, the linear module 9, grating transmitter 14, grating receiver 15, hydraulic cylinder 31, second electric push rod 35, electric roller 63, first electric push rod 64 and belt conveyor 72 are all electrically connected to the equipment controller via wires (not shown in the figure). The controller can be a PLC controller, and its specific control logic can be implemented by programming with existing technology, which will not be elaborated further here.

[0027] When using this device, the thickness parameters of the strap to be processed are first adjusted: the first electric push rod 64 drives the bracket 62 to move up and down, adjusting the distance between the two electric rollers 63 to match the thickness of the strap. Then, the linear module 9 drives the feeding rack 61 above it to move to the left, so that the two feeding racks 61 are close together. The belt conveyor 72 on the top left of the processing table 1 transports the strap to be processed to the feeding rack 61. After the strap is guided by the guide plate 66, it enters between the two electric rollers 63. The two electric rollers 63 rotate and drive the strap to be transported to the other two electric rollers 63. The two electric rollers 63 clamp the strap under the drive of the first electric push rod 64. Then, the linear module 9 drives the two electric rollers 63 clamping the strap to move to the right. The second electric push rod 35 drives the stamping die 33 to move back and forth, adjusting the relative position of the riveting head 32 and the stamping die 33 to align with the riveting point. At this time, the strap is straightened and placed on the stamping die 33. Next, the hydraulic cylinder 31 is activated, driving the riveting head 32 to move downwards and cooperate with the stamping die 33 to complete the riveting and fixing of the rivet. After the riveting is completed, the hydraulic cylinder 31 drives the riveting head 32 to reset, and the linear module 9 is activated again, driving the back strap clamped by the two electric rollers 63 to move to the right until the guide plate 66 on the bracket 62 moves to the top right of the belt conveyor 72 on the processing table 1. The two electric rollers 63 continue to transport the back strap, so that the back strap automatically falls onto the belt conveyor 72 via the guide plate 66 to complete the unloading. Then, the back strap is processed according to the above processing steps to realize the cycle operation.

[0028] During the processing, the grating transmitter 14 and the grating receiver 15 are always in working condition, forming a safety protection to ensure the safety of the staff; if it is necessary to change the straps or rivets of different specifications, simply repeat the above adjustment steps without disassembling the entire device, making the operation convenient.

[0029] like Figure 7As shown, each of the two feeding racks 61 has a limit groove 10 on its rear wall. Each support 62 has a detachable limit block 11 connected to its front end. The limit block 11 is located in the limit groove 10. The limit block 11 cooperates with the limit groove 10 to guide and limit the lifting process of the support 62, preventing the support 62 from shifting during lifting and ensuring that the upper and lower electric rollers 63 can be accurately aligned, thus ensuring the stability of the belt conveyor.

[0030] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, a grating transmitter 14 and a grating receiver 15 are respectively installed on both sides of the top of the processing table 1. The grating transmitter 14 and the grating receiver 15 cooperate to form a safety protection grating. When the worker's limb enters the riveting processing area, the grating is blocked, and the device immediately stops operating to avoid safety accidents and improve the operational safety of the device.

[0031] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
