[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] A new type of electric roller, please refer to Figure 1-2 , including a main roller 1, an auxiliary roller 2 and a material guide roller 3. The main roller 1 and the auxiliary roller 2 are used to roll PETG raw materials to produce films or sheets. The material guide roller 3 guides the raw materials so that they are flattened and enter between the main roller 1 and the auxiliary roller 2. This structure also includes a pair of first mounting plates 4 and a pair of second mounting plates 5. The first mounting plates 4 are relatively parallel to each other, and the second mounting plates 5 are relatively parallel to each other. The two shaft ends of the main roller 1 and the auxiliary roller 2 are both rotatably connected to the first mounting plates 4, and the two shaft ends of the material guide roller 3 are rotatably connected to the second mounting plates 5. In addition, the first mounting plate 4 and the second mounting plate 5 are pinned together by a pin 6; a cylinder 7 is rotatably connected to the second mounting plate 5, and the telescopic end of the cylinder 7 is rotatably connected to the first mounting plate 4. Specifically, a cylinder base 19 is rotatably connected to the second mounting plate 5 via a rotating shaft 21. The cylinder 7 is fixed to the cylinder base 19. The telescopic end of the cylinder 7 is fixedly connected to a connecting block 20, and the connecting block 20 is rotatably connected to the first mounting plate 4.

[0022] When the cylinder 7 is extended or retracted, it can drive the first mounting plate 4 to rotate, thereby fine-tuning the gap between the main roller 1 and the auxiliary roller 2. The width of the gap corresponds to the thickness of the feed raw material, so that the raw material can be pre-calendered according to the thickness, fluidity and other characteristics of its original raw material before being guided between the main roller 1 and the auxiliary roller 2, so that the material has better fluidity before entering the main calendering area, which helps to reduce stress concentration inside the material, eliminate air and bubbles in the material, eliminate wrinkles, ripples and other irregularities in the raw material, and make the raw material smoother before entering the main roller 1 and the auxiliary roller 2.

[0023] As an embodiment of the present invention, a slide groove 401 is provided on the side of the first mounting plate 4, and the mouth of the slide groove 401 is connected to the baffle 8, and a through hole 801 is provided on the baffle 8, and a shaft rod 9 is inserted into the through hole 801, and one end of the shaft rod 9 is fixedly connected to a screw 10 coaxially arranged therewith, and a slide seat 11 is slidably connected in the slide groove 401, and a square groove 111 is provided on the slide seat 11, and a hole is provided on the slide seat 11 for the screw 10 to pass through, and a screw nut 12 threadedly connected to the screw 10 is embedded in the square groove 111. The other end of the shaft 9 extends out of the slide groove 401 and is coaxially connected to the worm gear 13. A bracket 14 is fixed on the first mounting plate 4, and a worm 15 is rotatably connected to the bracket 14. The worm gear 13 is meshed with the worm 15, and the worm 15 is driven to rotate by a motor (not shown in the figure). The worm 15 drives the worm gear 13 to rotate, and the worm gear 13 drives the shaft 9 and the screw 10 to rotate. The screw 10 drives the screw nut 12 to move along its axial direction. The screw nut 12 drives the slide 11 as a whole to move along the slide groove 401 during the movement. The shaft end of the auxiliary roller 2 is connected to the slide 11 by rotation. When the slide 11 moves, it can change the gap between the auxiliary roller 2 and the main roller 1, thereby adjusting the rolling thickness.

[0024] Among them, on the inner side of the first mounting plate 4 on one side, the axial ends of the main roller 1, the auxiliary roller 2 and the material guide roller 3 are coaxially connected with the first gear 16, the second gear 17 and the third gear 18 respectively, and the first gear 16 and the second gear 17 are meshed and connected. The shaft end of the main drum 1 is connected to the driving motor, the first gear 16 rotates with the main drum 1, the second gear 17 rotates with the first gear 16 and drives the auxiliary drum 2 to rotate, and the rotation directions of the main drum 1 and the auxiliary drum 2 are opposite, so that the main drum 1 and the auxiliary drum 2 are driven by a single motor to synchronously roll the raw materials; in addition, the first gear 16 and the third gear 18 are meshed and connected, even the guide drum 3 rotates synchronously with the main drum 1; the utility model is used for manufacturing thin film materials, and when the gap is fine-tuned, the first gear 16 and the third gear 18, the first gear 16 and the second gear 17 maintain a high degree of meshing, and when the cylinder 7 increases the elongation and the slide 11 moves away from the main drum 1, the first gear 16 and the third gear 18, the first gear 16 and the second gear 17 can be disengaged, so that the main drum 1, the auxiliary drum 2 and the guide drum 3 are separated, which is convenient for cleaning the residual materials, maintaining the machinery and inspecting the drum surface condition in the later stage.

[0025] In this embodiment, the pin 6 is connected to the bottom of the first mounting plate 4 near the auxiliary roller 2, and the connecting block 20 is connected to the edge of the first mounting plate 4 near the main roller 1. This structure improves the gravity distribution and enhances the responsiveness of the cylinder 7 to the gap between the main roller 1 and the material guide roller 3.

[0026] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
