[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0019] Reference Figure 1As shown, a melt length detection device includes a graduated platform 7, a guide groove 71 on the top of the graduated platform 7, a scale 72 fixedly connected to the rear side of the top of the graduated platform 7, a guide rail 6 fixedly connected to the bottom of the guide groove 71, a slider 4 on the top of the guide rail 6, a sliding groove 41 on the bottom of the slider 4, the top surface of the guide rail 6 slidingly connected to the inside of the sliding groove 41, a movable block 3 fixedly connected to the top of the slider 4, the front and rear side walls of the movable block 3 slidingly connected to the inner wall of the guide groove 71, and a slot 31 on the top of the movable block 3. The graduated platform 7 and the movable block 3... The top is equipped with a melt 1. Before use, the movable block 3 is moved to a suitable size range according to the length of the melt 1 to be inspected, and the straight thread screw 5 is tightened clockwise to fix the position of the movable block 3. The support block 2 is moved to place the melt 1 on the top of the scale platform 7. The support block 2 is used to support the middle of the melt 1 to prevent the melt 1 from sagging. The scale platform 7 and the slot 31 are used to limit the left and right ends of the melt 1 respectively. The length of the melt 1 is checked by comparing the tightness of the melt 1. The structure is simple, the operation is convenient, the detection efficiency is improved, and the accuracy of the detection results is guaranteed.
[0020] Furthermore, such as Figure 2 As shown, the scale platform 7 has movable grooves 8 on both its front and rear sides. Threaded screws 5 are slidably installed inside each of the two movable grooves 8. The movable block 3 has threaded holes 32 on both its front and rear sides. The ends of the two threaded screws 5, which are close to each other, are threaded into the two threaded holes 32. The left end of the melt 1 is located on the left side of the scale platform 7, and the right end of the melt 1 is located inside the slot 31. A support block 2 is provided inside the guide groove 71. A groove 21 is formed at the bottom of the support block 2.
