[0007] Preferably, two connecting rods are fixedly provided on the top of the cutting disk, a protrusion is fixedly connected to the inner wall of the inner sleeve, the connecting rods are movably inserted into the protrusion, and a spring is movably sleeved on the connecting rods, and the spring pushes the cutting disk downward to be flush with the inner sleeve.

[0008] An outer sleeve is provided on the inner sleeve, and the inner sleeve is slidably connected inside the outer sleeve, a top spring cooperating with the inner sleeve is provided inside the outer sleeve, and an annular ramp is fixedly provided at the bottom end of the outer sleeve, an outer ring cooperating with the ramp is fixedly provided at the top end of the inner sleeve, a retaining ring cooperating with the outer ring is fixedly provided inside the outer sleeve, and the bottom end of the inner sleeve abuts against the top end of the connecting rod.

The four corners of the top of the cutting disk are rotatably connected with turntables for clamping the filling blocks, and the turntable is provided with notches for the filling blocks to move upward.

[0010] Preferably, a cross beam is fixedly provided inside the outer sleeve, the outer sleeve is rotatably connected to the cross beam, the top of the inner sleeve is slidably connected to a rectangular frame pushed by the inner sleeve, and a fork corresponding to the turntable is fixedly connected to the rectangular frame, and the top of the turntable is provided with an oblique groove matching the fork.

[0012] Preferably, an ear seat with a hole is fixedly provided on the side surface of the outer sleeve, and the ear seat of the outer sleeve sleeve and bolts are fixed on the pressure plate.

[0013] Preferably, a hexagonal head is fixedly provided on the top end of the outer sleeve.

[0014] A method for using a cutting device for medical-grade recombinant collagen repair dressing comprises the following steps: S1. The pressure plate moves downward, so that the inner sleeve and the cutting plate press and fix the dressing downward along the dressing channel. The outer sleeve continues to move downward, so that the inner sleeve and the cutting plate move upward relatively. During this process, the connecting rod pushes the inner sleeve upward, so that the top spring is compressed and enters the outer sleeve until the inner sleeve is aligned along the retaining ring. At this time, the inner sleeve moves downward in alignment with the connecting rod and hits the connecting rod to press the cutting plate into the cutting groove to cut the dressing; S2, rotating the outer sleeve so that the inclined platform inside it turns to the opposite direction. At this time, the top spring pushes the inner sleeve to change the direction of the inclined platform along the inclined platform, and the oppositely inclined inner sleeve pushes the rectangular frame to shift. In this process, the shift fork pushes the turntable to rotate along the inclined slot to adjust the missing slot; S3. According to the cutting requirements, when the outer sleeve is not used to rotate the turntable, the turntable blocks the filling block along the notch. At this time, the filling block is combined with the cutting disc to completely cut the dressing from the material belt. After the outer sleeve is used to rotate the turntable, the notch is aligned with the filling block, and the upper end of the filling block loses its constraint. At this time, it can slide freely along the notch. Therefore, the filling block cannot move downward with the force of the cutting disc, but is restricted by the material belt. That is, the filling block is pushed back by the material belt and moves up along the notch. At this time, parts of the four corners of the cut dressing are left connected to the material belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the inner sleeve is pushed up by the connecting rod to compress the top spring and enter the outer sleeve until the inner sleeve is aligned along the retaining ring. At this time, the inner sleeve and the connecting rod are aligned and moved downward, and hit the connecting rod to press the cutting disk into the cutting groove to cut the dressing. In this way, the dressing is pressed flat by the flat surface of the combination of the inner sleeve and the cutting disk before cutting, thereby improving the pressing flatness of the dressing, and the inner sleeve is used to convert the downward pressure of the pressure plate. Regardless of the downward movement speed of the pressure plate, the inner sleeve can always maintain a constant impact cutting effect, thereby ensuring the anti-interference ability of the equipment's cutting operation.

[0016] In the present invention, the filling block is integrated with the cutting disc to completely cut the dressing from the material belt. After the turntable is rotated to align the notch with the filling block, when the cutting disc cuts downward, the filling block is pushed back by the material belt and moves upward along the notch, so that parts of the four corners of the dressing are left connected to the material belt. In this way, the cutting disc can be controlled to realize the cutting function of the dressing without separating it temporarily in addition to the complete cutting function, so that the dressing can be synchronously brought out by the material belt for other processing such as lamination.

[0017] In the present invention, the inclined platform inside the outer sleeve is turned to the opposite direction, and the top spring pushes the inner sleeve to change the inclined direction synchronously along the inclined platform, and the inner sleeve inclined in the opposite direction pushes the rectangular frame to shift. In this process, the shift fork pushes the turntable to rotate along the inclined groove to adjust the missing groove. On the one hand, the shift fork can perform linear displacement of a fixed track along the top of the cutting disk. When the cutting disk is tilted, the shift fork can push it to reset, thereby achieving the detection and correction effect. Based on the linkage design of the outer sleeve and the inner sleeve, the following technical advantages are achieved: ‌Efficient adjustment‌: The notch angles of multiple turntables can be synchronously controlled by rotating the outer sleeve, and the synergy of the inclined table and the top spring can be used to achieve one-key switching of the inner sleeve tilt direction, eliminating the tedious operation of manual adjustment one by one, and improving the adjustment efficiency by more than 50%; ‌Easy to operate‌: The sliding cooperation between the fork and the inclined slot converts the linear displacement into the rotation of the turntable. With the linkage shift mechanism of the rectangular frame, the operator only needs to rotate the outer sleeve to complete the multi-level adjustment, which significantly reduces the complexity of operation; ‌Structural linkage‌: The change in the angle of the inclined platform, the elastic potential energy of the top spring and the tilt direction of the inner sleeve form a three-level power transmission chain. The mechanical self-locking feature ensures the stability after adjustment, avoiding the rebound error that is prone to occur in traditional manual adjustment; ‌Precise adjustment‌: The slot angle is precisely controlled by the circumferential angle of the inclined slot, and the adjustment resolution can reach ±1.5°, meeting the positioning requirements of precision equipment; ‌Applicability Expansion‌: The modular design supports synchronous control of multiple turntables. By adjusting the inclination parameters of the inclined table, it can adapt to turntable systems of different specifications. It has wide applicability in the field of automation equipment adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
