This limits the applicability of slitting machines. When faced with protective film slitting tasks with various width requirements, it is necessary to frequently change guide roller sets of different specifications, which is cumbersome, time-consuming, and costly.

[0045] Example

[0046] Please see Figure 1-4This utility model provides the following technical solution: an adjustable-width guide roller group for a protective film slitting machine, comprising:

[0047] Fixed rail 1, symmetrically distributed;

[0048] Square rod 2, with both ends fixedly connected to the inner side of fixed rail 1, and roller frame 3 slidably installed on the surface of square rod 2, and guide roller 4 rotatably installed inside roller frame 3;

[0049] Slide 5 is slidably installed inside the fixed rail 1. A transparent scale 6 is fixedly connected to the surface of slide 5, and a marking needle 7 is fixedly connected to the upper surface of roller frame 3.

[0050] Support component 8 includes:

[0051] The fixing seat 801 is fixedly installed on the lower surface of the fixing rail 1;

[0052] Bearing 802 is embedded inside the fixed base 801;

[0053] A lead screw 9 is fixedly connected to the inner wall of bearing 802. The lead screw 9 is threadedly connected to roller frame 3. A connector 10 is fixedly connected to one end of the lead screw 9.

[0054] Fixed rail 2 11 is fixedly connected to one side of fixed rail 1, and slide block 2 12 is slidably installed inside fixed rail 2 11;

[0055] Drive mechanism 13.

[0056] The present invention provides a technical solution in which the drive mechanism 13 drives the lead screw 9 to rotate, thereby realizing the automatic movement and adjustment of the roller frame 3 and the guide roller 4. This greatly saves adjustment time and labor costs, improves adjustment efficiency, and can flexibly adjust the position of the guide roller 4 according to the slitting requirements of protective films of different widths, meeting diverse production requirements and improving the versatility and practicality of the equipment. There is no need for manual replacement of the guide roller assembly. By setting a transparent scale 6 and a marking needle 7, the operator can intuitively understand the adjustment width through the indication of the marking needle 7 on the transparent scale 6 during the adjustment of the guide roller 4, ensuring the positional accuracy of the guide roller 4. The support assembly 8 uses symmetrically distributed fixed seats 801 and bearings 802 to support the lead screw 9, reducing the shaking of the lead screw 9 when rotating. At the same time, the square rod 2 guides the sliding of the roller frame 3.

[0057] Furthermore, the drive mechanism 13 includes:

[0058] The top of the L-shaped support plate 1301 is slidably connected to the slide block 12. The bottom of the L-shaped support plate 1301 is fixedly mounted with a servo motor 1302. The output end of the servo motor 1302 is fixedly connected with a reducer 1303. The output end of the reducer 1303 is fixedly connected with a plug plate 1304.

[0059] Furthermore, the surface of the connector 10 is provided with a groove 1001 that is adapted to the insert plate 1304.

[0060] Specifically, the L-shaped support plate 1301 can slide horizontally within the slide block 12, thereby facilitating the adjustment of the position of the servo motor 1302, so that the insert plate 1304 can be inserted into or detached from the groove 1001. Power is provided by the servo motor 1302, and after being reduced by the reducer 1303, the insert plate 1304 is rotated, which in turn drives the lead screw 9 to rotate through the connector 10, thereby driving the roller frame 3 to move horizontally along the direction of the square rod 2.

[0061] Furthermore, a wheel body 501 is rotatably mounted inside the slide 5, and every two slides 5 are connected to both ends of the transparent scale 6 respectively. The transparent scale 6 is located above the roller frame 3 and the marking needle 7.

[0062] Specifically, wheel body 501 can reduce the resistance between slide block 5 and fixed rail 1, thereby making the transparent scale 6 move more smoothly horizontally. The marking needle 7 can be seen directly through the transparent scale 6. The marking needle 7 can coincide with the scale on the transparent scale 6, so the position and adjustment width of the guide roller 4 can be directly reflected. In addition, it can also make it easier for operators to calculate the width distance between each guide roller 4.

[0063] Furthermore, the fixed rail 2 11 has a rotating wheel body 2 1101 inside, and the wheel body 2 1101 is arranged in a horizontal array.

[0064] Specifically, the wheel body 1101 helps to reduce the resistance between the slide block 12 and the fixed rail 11, thereby making the horizontal sliding of the slide block 12 and the adjustment of the drive mechanism 13 smoother.

[0065] Furthermore, an L-shaped support leg 14 is fixedly installed on the lower surface of the fixed rail 1, and an insertion hole 1401 is opened on the surface of the L-shaped support leg 14.

[0066] Specifically, the guide roller assembly can be fixedly installed on the frame of the slitting machine via the L-shaped support leg 14, and the insertion hole 1401 is used to insert the fixing bolt.

[0067] Furthermore, the support components 8 are symmetrically distributed, and the two ends of the lead screw 9 are respectively connected to the bearings 802.

[0068] Specifically, the symmetrically distributed support components 8 can improve the balance and stability of the lead screw 9 and prevent it from shaking when rotating.

[0069] The working principle or usage process of this utility model is as follows: When it is necessary to adjust the width of the guide roller group, firstly, the target position of the guide roller 4 is determined according to the required width of the protective film to be slit. Then, the sliding block 12 is moved to slide and adjust the drive mechanism 13 within the fixed rail 11. The drive mechanism 13 stops when it moves to the end of the lead screw 9 corresponding to the guide roller 4 to be adjusted. Then, the servo motor 1302 is pushed to slide within the sliding block 12 through the L-shaped support plate 1301 until the insert plate 1304 is inserted into the groove 1001 of the connector 10 at the end of the lead screw 9, thus connecting the drive mechanism 13 with the lead screw 9. Next, the servo motor 1302 is started, and the output shaft of the servo motor 1302 rotates. After being reduced in speed by the reducer 1303, the insert plate 1304 rotates. The insert plate 1304 drives the lead screw 9 to rotate within the bearing 802 through the connector 10. Since the lead screw 9 is threadedly connected to the roller frame 3, the rotation of the lead screw 9 is converted into... The roller frame 3 moves linearly along the length of the square rod 2, thereby driving the guide roller 4 to move. During the movement of the roller frame 3, the marking needle 7 on the roller frame 3 will move together with the roller frame 3. The operator can observe the scale indicated by the marking needle 7 through the transparent scale 6 to understand the position of the guide roller 4 in real time. When the position of the marking needle 7 reaches the target width, the servo motor 1302 is turned off to complete the position adjustment of the guide roller 4. After the adjustment is completed, the L-shaped support plate 1301 is moved so that the insert plate 1304 is disengaged from the groove 1001 of the connector 10, so as to carry out the next adjustment of the guide roller 4 at different positions or other operations. During the protective film slitting process, the protective film runs smoothly under the guidance and support of the guide roller 4. The L-shaped support leg 14 ensures the stability of the entire guide roller group and ensures the smooth progress of the slitting work. The electrical equipment in this equipment is all externally powered and controlled by the matching control switch to operate and shut down.
