[0016] Example 1: Preferred solutions include Figures 1 to 4 As shown, a surgical drape processing device with medical tape includes a frame 6, on which a medical tape unwinding mechanism is provided. The medical tape unwinding mechanism is used to install a medical tape roll 1. The medical tape of the medical tape roll 1 is picked up by a medical tape picking clamp 2, which includes a picking clamp 201. The picking clamp 201 is driven to move up and down by a lifting mechanism 202. The medical tape is cut by a cutting mechanism 3. The cut medical tape is transferred by a transfer clamp 4, which includes a feeding fixing clamp 401. The feeding fixing clamp 401 is installed on a slider 402. The slider 402 cooperates with a slide rail 403. The slider 402 is driven to move back and forth by a transverse drive mechanism. A connected transfer clamp 8 is provided on the frame 6. The connected transfer clamp 8 is used to move the medical tape to one end of an ultrasonic medical tape welding device 7. The ultrasonic medical tape welding device is used to weld the medical tape onto the surgical drape. The surgical drape is a gauze surgical drape, which is transported by a surgical drape conveyor belt 10. An ultrasonic medical tape welding device 7 is installed above the surgical drape conveyor belt 10. When the online transfer fixture 8 moves the medical tape above the surgical drape conveyor belt 10, the welding head of the ultrasonic medical tape welding device 7 moves downward to weld the medical tape onto the gauze surgical drape.

[0017] Furthermore, the medical tape unwinding mechanism is used to hold the medical tape roll. The unwinding mechanism includes an unwinding roller 501, a guide roller 502, and an end roller 503, with the end roller 503 located directly above the medical tape feeding fixture 2. The unwinding roller 501 can have its resistance adjusted by a damper, thus regulating the tension of the medical tape. The guide roller 502 can be a tension-adjustable guide roller.

[0018] Furthermore, the medical tape picking clamp 2 is used to pull the medical tape downwards by one end, and the stroke of the picking clamp 201 is the length of each picking. The lifting mechanism 202 is a cylinder, and the picking clamp 201 is a pneumatic clamp. The picking clamp 201 is used to hold the medical tape hanging down from the end roller 503.

[0019] Furthermore, the shearing mechanism 3 is located below the terminal roller 503. The shearing mechanism 3 includes a shear head 301 and a shearing mechanism frame 302. The shear head 301 is an electric or pneumatic shear, and the shearing mechanism frame 302 is provided with two limit rods 303, which are arranged vertically. The shear head 301 is driven to move by a cylinder. When the medical tape is laterally bent by the transfer clamp 4, the shear head 301 is activated to cut the medical tape.

[0020] The transfer fixture 4 also includes a pilot rod 404, which is installed at one end of the slider 402. The pilot rod 404 is used to pass through the gap between the two limiting rods 303 and to fold the medical tape from vertical to horizontal. The purpose of the pilot rod 404 is to cooperate with the two limiting rods 303 to fold the medical tape into a double-layered and horizontal state, so that the feeding clamp 401 can grasp the horizontally arranged medical tape. When the feeding clamp 401 transfers the double-layered medical tape to the online transfer fixture 8, the pneumatic chuck 801 of the online transfer fixture 8 can hold the double-layered medical tape and then transfer it horizontally above the surgical drape, so that the ultrasonic medical tape welding device 7 can weld the horizontal double-layered medical tape onto the surgical drape. In this embodiment, the medical tape is made of cotton of a certain thickness and has a certain degree of toughness.

[0021] Specifically, there are two feeding clamps 401, and the two feeding clamps 401 and the pilot rod 404 are located on the same plane. The feeding clamps 401 are used to clamp the medical tape in a horizontal position. When the opening angle of the feeding clamps 401 is greater than 180°, the cylinder for driving the feeding clamps 401 is not required. However, most clamps on the market have a maximum opening of less than 180°. In order to facilitate the feeding clamps 401 to clamp the medical tape in a horizontal position, the feeding clamps 401 need to be driven back and forth. The driving method of the feeding clamps 401 is as follows: the slider 402 includes two plates, the lower plate cooperates with the slide rail 403, and the upper plate is used to install the feeding clamps 401 and the pilot rod 404; the feeding clamps 401 are driven to move by the feeding clamp push cylinder 405, or the upper plate of the slider 402 is driven to move by the feeding clamp push cylinder 405.

[0022] The online transfer fixture 8 includes a pneumatic chuck 801, which is driven to move up and down by a lifting cylinder 802. The lifting cylinder 802 is mounted on a movable seat 803, which is slidably mounted on a guide rail 804. The movable seat 803 is driven to move by a transverse drive mechanism. The function of the online transfer fixture 8 is to transfer the horizontally positioned medical tape to above the surgical drape. Specifically, the medical tape needs to be transferred to above the surgical drape conveyor belt 10, and then the lifting cylinder 802 is driven downward to press the medical tape onto the surgical drape. The pneumatic chuck 801 includes two vertically movable clamping plates, which are concave plates. The principle of the concave plates is similar to the pressure head of a sewing machine. When the two concave plates clamp the medical tape, a portion of the medical tape is exposed in the middle of the concave plates. This portion is the working area of ​​the welding head of the ultrasonic medical tape welding device 7.

[0023] like Figure 5-11 As shown, the operating method of a gauze surgical towel processing device with medical straps includes the following steps: Step 1, Unwinding operation: Place the medical tape roll on the unwinding roller 501, and the medical tape passes around the guide roller 502 and the terminal roller 503 in sequence, with the front end of the medical tape hanging down naturally; Step 2, Medical belt picking clamp 2 action: Lifting mechanism 202 drives picking clamp 201 to rise, picking clamp 201 clamps the front end of medical belt, lifting mechanism 202 drives picking clamp 201 to fall, picking clamp 201 pulls medical belt down a distance. Step 3, Transfer Fixture 4 Action: Step 3.1, the slider 402 moves towards one end of the medical belt, the pilot rod 404 first contacts the medical belt and drives the medical belt to continue moving, after the pilot rod 404 passes through the two limiting rods 303, the limiting rods 303 cooperate with the pilot rod 404 to fold the medical belt into a double-layered and horizontal state; Step 3.2, the feeding clamp 401 clamps the medical tape in the horizontal position; Step 4, the cutting mechanism 3 operates: the shear head 301 cuts the medical tape; Step 5, the transfer fixture 4 operates again: the slider 402 moves in the opposite direction, transferring the cut medical tape to one end of the online transfer fixture 8; Step 6, Online transfer fixture 8 action: Pneumatic chuck 801 clamps the medical tape, and moving seat 803 drives pneumatic chuck 801 to move towards one end of ultrasonic medical tape welding device 7. When pneumatic chuck 801 is moved to directly below ultrasonic medical tape welding device 7, it stops. Lifting cylinder 802 drives pneumatic chuck 801 to move downward and press the medical tape onto the surgical drape. Step 7, Ultrasonic medical tape welding device 7 operates: Ultrasonic medical tape welding device 7 welds the medical tape onto the surgical drape; Single-length material handling and welding completed.
