Technical Field
[0001] The utility model relates to the technical field of plastic processing equipment, in particular to a plastic product calender. Background Art
[0002] In the existing plastic product processing process, the calender is a commonly used equipment, which is used to make plastic raw materials into products such as films, sheets or plates through a calendering process. However, there are some problems with the traditional calender in actual use. For example, the existing calender can usually only process plastic products of a single thickness and cannot meet the diversified production needs; although some calenders use telescopic machines to control the gap between the two rotating rollers of the calender, there is still a certain time difference when the telescopic machine is closed, resulting in a large error in controlling the gap between the two rotating rollers. In view of this, we propose a plastic product calender to solve the above problems. Utility Model Content

[0006] As a further improvement of the technical solution, a scale is provided at the lower end of the two fixed plates, the scale is fixed on the baffle, and both ends of the scale are aligned with both ends of the slide groove.
[0007] As a further improvement of the technical solution, the second rotating roller and the third rotating roller are on the same horizontal plane.
[0008] As a further improvement of the technical solution, the length of half of the movable plate between the fixed plate and the fixed nail is much smaller than the length of the other half of the movable plate.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] 1. In the plastic product calender, sliding holes are arranged at the baffles at both ends of the fixed shaft, telescopic machines are arranged on the sides of both ends of the fixed shaft, a movable plate is arranged above the telescopic machine, a fixing nail is arranged in the middle of the movable plate, and a fixed plate is arranged at the other end of the movable plate, and the length of half of the movable plate between the fixed plate and the fixing nail is much smaller than the length of the other half of the movable plate.

Since the length of half of the movable plate between the fixed plate and the fixing nail is much smaller than the length of the other half of the movable plate, the telescopic length of the telescopic machine is very large, while the range of movement of the fixed shaft is relatively small. When the time difference of closing the telescopic machine is the same, the error is reduced to a great extent, and the gap between the second rotating roller and the third rotating roller is adjusted more accurately, thereby improving the accuracy and quality of the product.

The baffle 1 at the end is provided with a sliding hole 11, and the fixed shaft 5 can slide in the sliding hole 11. Telescopic machines 12 are provided on the sides of both ends of the fixed shaft 5, and a third base 13 is provided below the telescopic machine 12. A movable plate 14 is provided above the telescopic machine 12. The movable plate 14 is hingedly connected to the telescopic machine 12, and a fixing nail 15 is provided in the middle of the movable plate 14. A fixed plate 16 is provided at the other end of the movable plate 14. When the telescopic machine 12 is extended or retracted, the movable column 18 on the movable plate 14 slides in the groove 17, so that the sliders 19 at both ends of the fixed plate 16 move in the slide groove 20, driving the fixed shaft 5 connected to the fixed plate 16 to move together, thereby adjusting the gap between the second rotating roller 3 and the third rotating roller 4.
[0020] Specifically, a groove 17 is provided on the side of the fixed plate 16 close to the movable plate 14, and a movable column 18 is provided on the end of the movable plate 14 close to the groove 17. The movable column 18 is slidably connected with the fixed plate 16 in the groove 17. Slide blocks 19 are provided at both ends of the side of the fixed plate 16 close to the baffle 1.

[0021] Furthermore, a scale 21 is provided at the lower end of the two fixed plates 16, and the scale 21 is fixed on the baffle 1. Both ends of the scale 21 are aligned with both ends of the slide groove 20, so that the adjusted distance can be intuitively seen, thereby avoiding large errors in the adjustment, and further making the gap between the second rotating roller 3 and the third rotating roller 4 more accurately adjusted, thereby improving the accuracy and quality of the product.
[0022] Furthermore, the second rotating roller 3 and the third rotating roller 4 are on the same horizontal plane, so that the sliding hole 11 is also set to be horizontal, which is convenient for moving the position of the fixed shaft 5, thereby facilitating the movement of the position of the third rotating roller 4, and further facilitating the adjustment of the gap between the second rotating roller 3 and the third rotating roller 4, thereby realizing the processing of plastic products of different thicknesses.
[0023] In addition, the length of half of the moving plate 14 between the fixed plate 16 and the fixed nail 15 is much smaller than the length of the other half of the moving plate 14. Since the length of half of the moving plate 14 between the fixed plate 16 and the fixed nail 15 is much smaller than the length of the other half of the moving plate 14, the telescopic length of the telescopic machine 12 is very large, while the moving range of the fixed shaft 5 is relatively small. When the time difference for closing the telescopic machine 12 is the same, the error is greatly reduced, and the gap between the second rotating roller 3 and the third rotating roller 4 is adjusted more accurately, thereby improving the accuracy and quality of the product.
[0024] Working principle: When the thickness of the plastic product needs to be changed, first start the telescopic machine 12 to make it telescopic, so that the moving column 18 on the moving plate 14 slides in the groove 17, so that the sliders 19 at both ends of the fixed plate 16 move in the slide 20, driving the fixed shaft 5 connected to the fixed plate 16 to move together, and then adjust the gap between the second rotating roller 3 and the third rotating roller 4, and then adjust it by looking at the scale 21. When the distance is adjusted to the required distance, close the telescopic machine 12, and then start the first motor 7, the second motor 9 and the fan 6 respectively, and then throw the material between the second rotating roller 3 and the third rotating roller 4, and then be squeezed by the second rotating roller 3 and the third rotating roller 4, and after being blown by the fan 6 to cool and shape, it is wrapped around the first rotating roller 2 for rolling.
