DETAILED DESCRIPTION

Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

As shown in Fig. 1-3, a length-adjustable roller cutting device comprises a frame 1, two vertical first through slots 2 are symmetrically arranged on one end of the frame 1, a conveying roller 3 and a pressure roller 4 with adjustable positions are arranged in the two first through slots 2, the pressure roller 4 is located above the conveying roller 3, a freely rotatable cutting roller 5 is arranged at the other end of the frame 1, a cutting knife 6 is arranged on the cutting roller 5, wherein a first gear 7 and a second gear 8 are arranged at one end of the conveying roller 3 and the cutting roller 5, respectively, a synchronous wheel 9 is connected to the other end of the cutting roller 5, and the synchronous wheel 9 is connected to the motor through a belt, and the conveying roller 3 is equipped with the first gear 7. One end is also coaxially connected to an adjusting rod 10, which includes a rod body 101 and an arc-shaped portion 102. The rod body 101 and the arc-shaped portion 102 are respectively provided with a second through groove 1011 and an arc-shaped third through groove 1021. The second through groove 1011 is provided with one or more third gears 11 for transmitting the first gear 7 and the second gear 8. A fixing bolt 12 is also provided on the side of the frame 1, and the fixing bolt 12 passes through the third through groove 1021. A material-carrying support plate 13 is provided on the frame 1 and between the cutting roller 5 and the conveying roller 3. The support plate 13 is fixed to the frame 1 in an adjustable height.

Mounting ears 14 are provided on both sides of the support plate 13. The mounting ears 14 have fourth through slots, and the mounting ears 14 are slidably connected to the frame 1 through the fourth through slots. Based on the mounting ears 14 and the fourth through slots, the position of the support plate 13 can be adjusted.

One end of one or more third gears 11 can be slidably disposed in the second through slot 1011. The third gear 11 can be adjusted by sliding to adapt to different heights of the first gear 7 in the first through slot 2.

A material unloading assembly is also provided below the cutting roller 5, and the material unloading assembly includes two material unloading rollers 15 and a plurality of synchronous belts 16 wound on the two material unloading rollers 15. The material unloading assembly can receive the cut material.

Working principle:

During operation, a motor (not shown in the figure) drives the cutting roller 5 to rotate, thereby driving the second gear 8 at the other end of the cutting roller 5. The second gear 8 then drives one or more third gears 11. The third gear 11 drives the first gear 7, thereby rotating the conveying roller 3. The coiled material passes from between the conveying roller 3 and the pressure roller 4 onto the support plate 13. When it reaches the position of the cutting roller 5, the cutter 6 of the cutting roller 5 rotates and cuts, and the cut material falls onto the unloading assembly.

If the length of the material after cutting needs to be changed, the number or size of the third gear 11 is adjusted to change the speed ratio of the first gear 7 and the second gear 8. For example, when the speed of the second gear 8, i.e., the cutting roller 5, becomes faster than the speed of the first gear 7, i.e., the conveying roller 3, the coiled material will be cut shorter, and vice versa. At the same time, in order to adapt to the new third gear 11, the height of the entire conveying roller 3 is adjustable, and the adjustment rod 10 can also change the inclination as the position of the third through slot 1021 and the fixing bolt 12 changes, so as to adapt to the new height of the first gear 7.

By adopting the above scheme, the beneficial effects of the utility model are:

Based on the conveying roller 3 that can slide in the first through slot 2 to adjust the height and the adjusting rod 10 that adjusts the position through the third through slot 1021, the number and size of the third gear 11 can be replaced and adjusted arbitrarily, and then the speed ratio between the conveying roller 3 and the cutting roller 5 can be changed, that is, the cutting length of the material can be changed. The utility model has a simple structure, high efficiency, low cost, and is easy to use and maintain.

Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
