[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] like Figure 1 , Figure 2 As shown, the heart stent guide wire rolling heat shrink device is installed on a mechanism placement frame 8, and the related electrical control box 1 is fixed on the frame 8 and can be used as an operating table. The specific wire rolling heat shrink device includes multiple groups of product support mechanisms 6, a pressing mechanism 2, a wire rolling mechanism 3, a heating mechanism 4, a product pushing and unloading mechanism 5 and a product box 7; the multiple groups of product support mechanisms 6 are distributed in sequence along the same axis, which can be used to place guide wires of different lengths to ensure placement stability. The product support mechanism 6 is provided with a groove for placing the guide wire, and also includes an inclined plate, which corresponds to the product box 7 in front of it to ensure that the falling guide wire can accurately fall into the product box 7, and multiple groups of product pushing and unloading mechanisms 5 are installed opposite to the product box 7. Figure 6 As shown, the product unloading mechanism 5 is driven by a cylinder, and its piston rod is fixedly connected to the push plate. An inclined baffle is also provided on the push plate to ensure the moving direction of the guide wire during the pushing process. Multiple groups of push plates are connected by connecting plates, and multiple push plates are also provided on the connecting plate to adapt to different product lengths and ensure the stability of the push.

[0026] The pressing mechanism 2 is driven by a cylinder, and the pressing slider connected to the cylinder piston rod is connected to the upper thread rolling mechanism in the thread rolling mechanism 3, and the lower thread rolling mechanism is fixed on the frame of the pressing mechanism 2, and is opposite to the upper thread rolling mechanism up and down, so that the upper thread rolling mechanism can be moved up and down into place, and then combined with the lower thread rolling mechanism to roll the thread. Figure 3 As shown, the pressing mechanism 2 is also provided with a limit buffer device, which includes an upper pressing plate 21, a guide column 22, a spring 23 and an adjusting nut 24. The upper pressing plate 21 and the spring 23 are sequentially sleeved on the guide column 22, and the upper pressing plate 21 contacts the pressing plate protruding from the side of the pressing slider. The adjusting nut 24 is used to adjust the compression amount of the spring 23 on the guide column 22. The pressing slider is driven by the cylinder and, under the action of the limit buffer device, can adjust the spacing between the upper thread rolling mechanism and the lower thread rolling mechanism, and can realize thread rolling processing of guide wires of different sizes.

[0027] like Figure 5 As shown, a limit plate is also installed on the side of the upper thread rolling mechanism, and a slot is provided at the bottom of the limit plate. The slot includes a straight limit groove at the top and a V-shaped groove at the bottom. The straight limit groove can ensure that the guide wire moves with the upper thread rolling mechanism, and the lower V-shaped groove is higher than the opposite side near the V-bend on the discharge side, which can be used to guide the falling direction of the guide wire.

[0028] like Figure 4As shown, the heating mechanism 4 includes a hot air heater, a connecting pipe and a limit block. The hot air heater is fixed on the frame of the pressing mechanism 2. The connecting pipe is used to connect the heater and the limit block to realize hot air transfer. An air outlet duct is provided inside the limit block, and a U-shaped groove is provided on the right side to accommodate the guide wire to pass through. Relative air outlets are provided on the upper and lower parts of the groove to make the guide wire heated evenly and ensure the heat shrinkage effect.

[0029] The specific usage method is as follows: after the product is manually placed on the product support mechanism 6, it is heated by the heater 4, and hot air is blown out for heat shrinkage. The lower pressing mechanism 2 descends, and after the upper thread rolling mechanism descends into place, the thread rolling is completed by rubbing back and forth. The lower pressing mechanism rises, and the upper cylinder of the product unloading mechanism 5 is pushed out to push the product into the product material box 7.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
