[0002] Paper printing is a technique that prints patterns, text, or images onto paper. It is widely used in publishing, advertising, packaging, and art. During the printing process using a printing press, to ensure accurate paper feeding and positioning, electric paper feed rollers are used to assist in the paper's transport.

[0003] However, in actual use, the pressure adjustment of the paper conveying electric roller structure generally requires the operator to manually adjust the roller position up and down to adapt to the tension of the conveyed paper. During the conveying operation, the operator often needs to make adjustments back and forth many times, which is quite cumbersome. It is not convenient to adjust the up and down position of the conveying electric roller to adapt to the tension when it is installed and used.

[0004] Now, a novel adaptive tension-adjustable electric paper conveying roller structure is proposed to address the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive tension-adjustable electric paper conveying roller structure to solve the problem of the cumbersome manual adjustment process of the electric paper conveying roller mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive tension-adjustable electric paper conveying roller structure, comprising a main frame, a base at the bottom of the main frame, and slide rods vertically fixed at the four corners of the top of the base, fixing feet fixed on both sides of the bottom of both ends of the main frame, and sliding holes provided inside the fixing feet, the top of the slide rod penetrating the interior of the sliding hole and fixed with a limit plate, and compression springs sleeved on the outer sides of the four sets of slide rods respectively.

[0007] As a further technical solution of this utility model, the top ends of the four sets of compression springs are fixedly connected to the bottom ends of the fixed feet, and the top ends of the four sets of compression springs are fixedly installed to the top ends of the base.

[0008] As a further technical solution of this utility model, a top frame is provided at the top of the main frame, and a pressure roller is provided horizontally inside the top frame. Slide grooves are respectively opened inside the two sides of the top frame, and slide blocks are slidably connected inside the slide grooves. Mounting bolts are respectively provided on both sides of the bottom of the two ends of the top frame, and two sets of mounting holes are respectively opened inside the two sides of the top of the main frame.

[0009] As a further technical solution of this utility model, the bottom end of the mounting bolt penetrates the interior of the top frame and is threadedly rotatably connected in the mounting hole.

[0010] As a further technical solution of this utility model, the grooves respectively penetrate the interior of both sides of the top frame, and the two sides of the pressure roller respectively penetrate the interior of the slide block.

[0011] As a further technical solution of this utility model, the front end of the main frame is provided with a mounting frame, and the two sides of the bottom of the front end of the mounting frame are respectively provided with fixing bolts. Several brushes are fixed to the top of the rear end of the mounting frame, and several brushes are fixed to the bottom of the rear end of the mounting frame. Inner holes are respectively opened on both sides of the bottom of both ends of the main frame.

[0012] As a further technical solution of this utility model, the rear end of the fixing bolt passes through the interior of the mounting bracket and is threaded into the inner hole, and the plurality of the first brush and the plurality of the second brush are distributed at equal intervals at the top and bottom of the rear end of the mounting bracket.

[0013] As a further technical solution of this utility model, a roller is movably connected laterally inside the main frame, a reducer is fixedly installed on the right side of the main frame, and a servo motor is fixedly installed on the right side of the reducer. The output shaft of the servo motor is fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is fixedly connected to the right side of the roller. Mounting feet are fixed on both sides of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the adaptive tension-adjustable paper conveying electric roller structure not only realizes the adaptive tension adjustment of the upper and lower positions when the conveying electric roller is installed and used, thus facilitating the auxiliary leveling of the conveyed paper, but also enables the auxiliary cleaning of the outer side of the conveying roller.

[0015] With a base, main frame, fixed feet, slide bars, compression springs, sliding holes, and limit plates, the electric conveyor roller structure can be installed and used to adapt to the paper conveying tension when the paper is being conveyed at the top of the roller and the paper conveying tension is relatively tight. The top conveying paper can push the roller down under the pull and compress the compression springs on the four sets of slide bars on the outside of the main frame. When the paper conveying tension slows down, the pressure at the top of the roller decreases, and the four sets of compression springs lose pressure and can rebound to push the roller up again for adjustment.

[0016] The electric roller is equipped with a main frame, top frame, pressure roller, mounting holes, slide block, mounting bolts and slide groove. During use, the top frame is installed on the top of the main frame. The internal pressure roller can move down and stick to the top of the roller body by its own weight. When the paper is conveyed on the top of the roller body, the pressure roller that rotates with it can help to flatten the paper surface.

[0017] The electric roller is equipped with a main frame, roller body, inner hole, brush one, mounting frame, brush two, and fixing bolts. When the roller is installed and used, several brush one and brush two are fixed inside the mounting frame installed at the front end of the main frame. During the rotation and conveying process of the roller body, several brush one and brush two can be used to assist in scraping and cleaning some dust, lint, and other debris adhering to the outside of the roller body, keeping the conveying surface of the roller body clean.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides an embodiment: an adaptive tension-adjustable paper conveying electric roller structure, including a main frame 3, a base 2 at the bottom of the main frame 3, and a slide rod 11 vertically fixed at the four corners of the top of the base 2. Fixed feet 10 are fixed on both sides of the bottom of both ends of the main frame 3, and a sliding hole 13 is provided inside the fixed foot 10. The top of the slide rod 11 passes through the interior of the sliding hole 13 and is fixed with a limit plate 14. Compression springs 12 are respectively sleeved on the outer sides of the four sets of slide rods 11.

[0025] The top ends of the four sets of compression springs 12 are fixedly connected to the bottom ends of the fixed feet 10, and the top ends of the four sets of compression springs 12 are fixedly installed to the top ends of the base 2.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, during the paper conveying process at the top of the roller 4, when the paper conveying tension is relatively tight, the top conveying paper can push the roller 4 down under the pull and compress the compression springs 12 on the four sets of slide bars 11 on the outside of the main frame 3 to adapt to the paper conveying tension. When the paper conveying tension slows down, after the pressure at the top of the roller 4 decreases, the four sets of compression springs 12 lose pressure and can rebound and push the roller 4 up again for adjustment, thus adapting to the tension adjustment conveying.

[0027] The top of the main frame 3 is provided with a top frame 5, and the inside of the top frame 5 is provided with a pressure roller 6. The inside of the top frame 5 is provided with a sliding groove 18 on both sides, and the sliding groove 18 is slidably connected to a slide block 16. The bottom of both ends of the top frame 5 is provided with mounting bolts 17. The inside of the top of the main frame 3 is provided with two sets of mounting holes 7 on both sides. The bottom end of the mounting bolt 17 passes through the inside of the top frame 5 and is threadedly connected to the mounting hole 7. The sliding groove 18 passes through the inside of both sides of the top frame 5, and the two sides of the pressure roller 6 pass through the inside of the slide block 16.

[0028] Specifically, such as Figures 1-3 As shown, the top frame 5 is installed on the top of the main frame 3. The internal pressure roller 6 can move down and stick to the top of the roller body 4 by its own weight. When the paper is conveyed on the top of the roller body 4, the pressure roller 6, which rotates with the top, can help to flatten the surface of the paper.

[0029] The front end of the main frame 3 is provided with a mounting frame 20, and the two sides of the bottom of the front end of the mounting frame 20 are respectively provided with fixing bolts 22. Several brushes 19 are fixed to the top of the rear end of the mounting frame 20, and several brushes 21 are fixed to the bottom of the rear end of the mounting frame 20. The two sides of the bottom of both ends of the main frame 3 are respectively provided with inner holes 15. The rear end of the fixing bolts 22 passes through the interior of the mounting frame 20 and is threaded into the inner hole 15. Several brushes 19 and several brushes 21 are distributed at equal intervals at the top and bottom of the rear end of the mounting frame 20.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, several brushes 19 and brushes 21 are fixed inside the mounting bracket 20 installed at the front end of the main frame 3. During the rotation and conveying process of the roller body 4, the brushes 19 and brushes 21 can be used to scrape and clean some dust, lint and other debris adhering to the outside of the roller body 4, so as to keep the conveying surface of the roller body 4 clean.

[0031] The main frame 3 has a roller 4 that is movably connected laterally inside. A reducer 8 is installed and fixed on the right side of the main frame 3, and a servo motor 9 is installed and fixed on the right side of the reducer 8. The output shaft of the servo motor 9 is fixedly connected to the input shaft of the reducer 8. The output shaft of the reducer 8 is fixedly connected to the right side of the roller 4. Mounting feet 1 are fixed on both sides of the base 2.

[0032] Working Principle: When the adaptive tension-adjustable electric paper conveying roller structure of this utility model is installed and used, during the paper conveying process at the top of the roller body 4, if the paper conveying tension is relatively tight, the top conveying paper, driven by the tension, can push the roller body 4 down and compress the compression springs 12 on the four sets of slide rods 11 on the outside of the main frame 3 to adapt to the paper conveying tension. When the paper conveying tension slows down, after the pressure at the top of the roller body 4 decreases, the four sets of compression springs 12 lose pressure and can rebound, pushing the roller body 4 back up for adjustment, thus achieving adaptive tension-adjustable conveying. At the same time, during the use of the electric roller, after the top frame 5 is installed on the top of the main frame 3, its internal pressure roller 6 can move down and stick to the top of the roller body 4 by its own weight. When the paper is conveyed at the top of the roller body 4, the pressure roller 6, which rotates with it at the top, can assist in flattening the paper surface. Furthermore, several brushes 19 and brushes 21 are fixed inside the mounting bracket 20 installed at the front end of the main frame 3. During the rotation and conveying process of the roller body 4, the brushes 19 and brushes 21 can be used to assist in scraping and cleaning some dust, lint and other debris adhering to the outside of the roller body 4, keeping the conveying surface of the roller body 4 clean.
