[0026] like Figures 1 to 5 As shown, the visual quick adjustment mark of the film mouth of the PVC sheet mold comprises a die mouth 1, a die sleeve 2 is welded on the top of the die mouth 1, a feed port 3 is opened inside the die sleeve 2, a bearing seat 4 is fixedly installed inside the die sleeve 2, a rotating rod 5 is rotatably connected inside the bearing seat 4, a rotating knob 6 is fixedly connected to the outside of the rotating rod 5, a movable plate 7 is threadedly connected to the surface of the rotating rod 5, a baffle 8 is fixedly installed on the side of the movable plate 7, a digital mark 10 is arranged on the outside of the die sleeve 2, an indicating arrow 11 is welded on the side of the rotating knob 6, and a limiting component 12 is arranged inside the rotating knob 6; specifically, by rotating the rotating knob 6, the rotating rod 5 can be driven to rotate, so that the two movable plates 7 and the baffle 8 move inward or outward at the same time, so that the size of the feed port 3 can be adjusted to change the discharge amount of the die mouth; the indicating arrow 11 and the digital mark 10 on the outside of the rotating knob 6 can facilitate the staff to understand the size of the adjusted die mouth; the rotating knob 6 can be fixed by the limiting component 12 to prevent the rotating knob 6 from rotating due to accidental touch, causing the movable plate 7 and the baffle 8 to shift.

[0027] like Figure 3 As shown, the surface of the rotating rod 5 is provided with two sections of external threads, and the directions of the two sections of external threads are opposite. The number of movable plates 7 is two, and the interiors of the two movable plates 7 are provided with internal threads, and the distribution of the internal threads of the two movable plates 7 is adapted to the two sections of external threads of the rotating rod 5; specifically, when the rotating rod 5 rotates, under the interaction of the two sections of external threads of the rotating rod 5 and the internal threads of the movable plates 7, the two movable plates 7 can move inward or outward at the same time.

[0028] like Figure 3 As shown, a limiting rod 9 is fixedly installed inside the mold sleeve 2, and the movable plate 7 is slidably connected to the limiting rod 9; specifically, the movable plate 7 can slide on the surface of the limiting rod 9 to play a limiting role.

[0029] like Figure 4 and Figure 5As shown, the limit assembly 12 includes a movable rod 1201, and the movable rod 1201 is arranged inside the rotating knob 6, a baffle plate 1203 is fixedly installed on the side of the movable rod 1201, and a clamping rod 1204 is welded on the side of the baffle plate 1203, and a clamping groove 1205 is opened on the outer side of the mold sleeve 2, and the clamping rod 1204 is adapted to the clamping groove 1205; specifically, the movable rod 1201 can drive the baffle plate 1203 and the clamping rod 1204 to move, and when the clamping rod 1204 is clamped in the clamping groove 1205, the rotating knob 6 can be fixed.

[0030] like Figure 5 As shown, a pull ring 1202 is fixedly connected to the outer side of the movable rod 1201, a tension spring 1206 is fixedly installed on the inner wall of the rotating button 6, and a baffle 1203 is fixedly connected to the other side of the tension spring 1206; specifically, pulling the pull ring 1202 can drive the movable rod 1201 to move, and when the movable rod 1201 is not pulled by external force, the elastic force of the tension spring 1206 will cause the baffle 1203 to move inward.

[0031] like Figure 4 and Figure 5 As shown, the number of digital identifications 10 and card slots 1205 is 12, and the 12 digital identifications 10 and the 12 card slots 1205 are equally divided on the outside of the rotating rod 5; specifically, the 12 digital identifications 10 and the 12 card slots 1205 correspond to each other, so that the indication arrow 11 of the rotating button 6 can point to the corresponding digital identification 10.

[0032] In summary: when it is necessary to adjust the discharge amount of the die mouth 1, the pull ring 1202 is pulled outward to make the clamping rod 1204 disengage from the clamping slot 1205, and the rotating knob 6 can be turned to drive the rotating rod 5 to rotate, so that the two movable plates 7 and the baffle 1 8 move inward or outward at the same time, so that the size of the feed port 3 can be adjusted to change the discharge amount of the die mouth. At the same time, 12 equally divided 1-12 digital marks 10 are added near the rotating knob 6 on the outside of the rotating rod 5, and the staff can judge the film mouth adjustment size by the position of the positioning indicator mark and the number. Compared with only being able to judge the adjustment size by phenomenon, it is more convenient and quicker for the staff to produce. When the discharge amount of the die mouth 1 is adjusted to the appropriate size, the pull ring 1202 is released, and under the elastic force of the tension spring 1206, the baffle 2 1203 is moved inward, which will make the clamping rod 1204 clamped in the clamping slot 1205, so that the rotating knob 6 will not rotate easily, thereby avoiding the staff from accidentally touching the rotating knob 6 and causing the film mouth size to change.
