[0002] Surgical incision protectors are a commonly used surgical consumable, and the TPU fixing ring that forms the surgical channel is an important component. The existing processing method mainly uses the method of melting the two ends of the TPU strip and then gluing the two ends together to make the TPU fixing ring. This method will form a circle of flaky burrs that overflow outward at the connection.

Due to the large demand and high output of TPU rings, the workload of the staff is high and the product processing completion requirements are high. New employees are not competent for deburring work, and the training cycle for skilled workers is too long, resulting in a decrease in product production efficiency. Employees work for a long time and at high intensity and need to use sharp tools, so the existing processing method still has certain safety hazards. Summary of the invention

The axial direction of the second slide rail 5a is perpendicular to the axial direction of the first slide rail 4h. A second slide rail 5b is provided on the second slide rail 5a. A first linear transmission device 5c corresponding to the second slide rail 5b is provided at one end of the second slide rail 5a. The first linear transmission device 5c can be a cylinder, an electric push rod or a linear motor in the prior art. Here, a cylinder is used.

[0023] A longitudinally distributed second slide rail 5k is connected to the longitudinal slide 5e, a corresponding longitudinal slider 5t is provided on the second slide rail 5k, a corresponding locking pin (not shown in the figure) is provided on the longitudinal slider 5t, and a cantilever 5h extending toward the direction of the TPU fixing ring clamping assembly 4 is connected to the longitudinal slider 5t, and a pneumatic scissors 6 is fixedly connected to one end of the cantilever 5h.

[0024] A retractable TPU fixing ring positioning assembly 7 is provided on the frame 1 below the table 2, and a clearance hole 7g corresponding to the TPU fixing ring positioning assembly 7 is provided on the table 2. The TPU fixing ring positioning assembly 7 includes a cylinder 7a distributed longitudinally on the frame 1, a platform is installed on the top of the output shaft of the cylinder 7a, a third slide rail 7b is provided on the platform, a corresponding sliding block is provided on the third slide rail 7b, a burr positioning block 7c is provided on the sliding block, and a burr clamping groove 7d corresponding to the burr on the TPU fixing ring is provided on the burr positioning block 7c.

[0026] Working process: First, according to the diameter of the TPU fixing ring 9, a second linear transmission device 5g and a longitudinal slider 5t are provided to adjust the scissor heads of the pneumatic scissors 5j to a suitable height.

[0027] Then the cylinder output extends the burr positioning block 7c out of the clearance hole 7g, which is located in the notch a1. Then the staff places the TPU fixing ring 9 on the placement plate 8, and inserts the sheet burr 9a of the TPU fixing ring 9 into the burr clamping groove 7d, and then clamps the TPU fixing ring 9 on both sides of the sheet burr 9a into the first clamping roller 4j and the second clamping roller 4k on both sides of the burr positioning block 7c, so that the TPU fixing ring 9 is clamped by the first clamping roller 4j and the second clamping roller 4k.

[0028] Then the second motor 4c starts, driving the screw 4b to rotate, so that the distance between the two nuts 4f on it increases by a certain distance, and at the same time, the distance between the two sliders 4g also increases by a certain distance driven by the nuts 4f. At this time, the first clamping roller 4j and the second clamping roller 4k located on the two sliders 4g will pull the TPU fixing ring 9 to both sides, so that the sheet burrs of the TPU fixing ring 9 are tightened, ensuring that there will be no wrinkles on the burrs, making it easier for the pneumatic scissors 5j to trim them, while also being able to perform quality inspection on the strength of the bonding part of the TPU fixing ring 9. At this time, the cylinder retracts so that the burr positioning block 7c retracts to the bottom of the table 2.

[0029] Finally, the first motor 3u is started to drive the frame 3b to rotate downward so that the placement plate 8 is in a vertical state, and then the first linear transmission device 5c is started to push the second slide 5b forward so that the blade of the pneumatic scissors 5j is aligned with the flaky burrs 9a, and then the pneumatic scissors 5j are started to cut off the flaky burrs 9a, and at the same time, the first motor 3u is started again to drive the frame 3b to rotate in the opposite direction so that the pneumatic scissors 5j gradually cut off all the flaky burrs 9a. After cutting, the whole device is reset.
