Detailed Implementation
[0025] The present invention will be further described below with reference to specific embodiments.
[0026] like Figure 1-3 As shown, the medical catheter melting head forming mechanism of this utility model includes a working platform 1. Two first guide rails 2 are provided on the working platform 1. These two first guide rails 2 are parallel to each other. Multiple first sliders 3 are provided on them for synchronous movement. The first sliders 3 can move back and forth on the first guide rails 2. A moving platform 4 is provided on these first sliders 3. All the first sliders 3 together drive the moving platform 4 to move back and forth on the working platform 1.
[0027] In terms of movement, since the mobile platform 4 is a relatively integral part, it is generally convenient for the staff to move the whole forward or make fine adjustments in distance before starting work for better operation. That is to say, the distance is not fixed and does not need to be adjusted frequently. Therefore, a handwheel 8 can be set at the front end. The staff only needs to turn the handwheel 8 to control the mobile platform 4 to move forward or backward as a whole.
[0028] The mobile platform 4 is equipped with a clamping component 5, a moving component 6, and a hot-melt component 7.
[0029] The movable component 6 includes a first fixed base 61 mounted on the movable platform 4. Two second guide rails 62 are respectively arranged on the left and right sides of the first fixed base 61, with the direction of these two second guide rails 62 being consistent with the direction of the first guide rail 62. A second slider 63 is provided on each of the two second guide rails 62, and a second fixed base 64 is provided on the second slider 63. The clamping component 5 is disposed on the second fixed base 64. Similarly, in this embodiment, two sets of clamping components 5 are provided, including a fixed clamping block 51 and a movable clamping block 52 for clamping the medical catheter. The fixed clamping blocks 51 are fixed in position and arranged close to each other. The movable clamping blocks 52 are correspondingly arranged on the outside of each set of clamping components 5, and are connected to a first driving member 53 in a direction perpendicular to the moving direction of the movable component 6. In this embodiment, the first driving member 53 is a motor.
[0030] Thus, the moving clamping block 52 can move relatively closer to / away from the fixed clamping block 51 through the driving action of the first driving member 53.
[0031] Meanwhile, the fixed clamping block 51 and the movable clamping block 52 are respectively provided with a fixed clamping groove 54 and a movable clamping groove 55 on the side surface of the contact. The shape formed by the two clamping grooves after they are attached matches the shape of the medical catheter to be heat-fused. Thus, the staff can insert the medical catheter to be heat-fused into the two clamping grooves and clamp the medical catheter by driving the movable clamping block 52.
[0032] After clamping, it enters the heat fusion assembly 7. The heat fusion assembly 7 includes a fixing plate 71 facing the clamping assembly 5, and a heating wire 72 disposed behind the fixing plate 71 for heat fusion of the head of the medical catheter. The fixing plate 71 is also provided with a fixing hole 73 for the medical catheter to pass through, and a melting head mold is embedded inside it, thereby further improving the stability of the heat fusion operation. At the same time, the setting of the fixing plate 71 can also improve safety.
[0033] Behind the heating wire 72, there is a nozzle 74 that can spray cooling water, which can quickly cool and shape the head of the conduit after the heat melting operation is completed, thereby completing the entire head heat melting operation.
[0034] like Figure 4 As shown, a movable plate 75 is also provided on the side of the fixed plate 71. Guide holes 76 are provided on the movable plate 75. In this embodiment, the number, position, shape, and size of the guide holes 76 match those of the fixed holes 73. A guide sleeve 78 is also provided on the guide holes 76. Through the guiding action of the guide sleeve 78 and the guide holes 76, precise alignment with the melting head mold can be achieved, improving the yield rate. A second driving component 77, typically a motor, is also connected to the side of the movable plate 75. Driven by the second driving component 77, the movable plate 75 can move horizontally. During normal operation, it is only necessary to control the movement of the movable plate 75 to align the guide holes 76 with the fixed holes 73. When not in operation, it is only necessary to control the movable plate 75 to move a very short distance so that other parts block the fixed holes 73.
