As shown in Figures 1 to 6, the utility model provides an automatic roll printing machine, including a printing device fixed to the upper end of a printing machine housing 1. The printing machine housing 1 can be fixed to a platform by a support plate or directly by screws. A winding reel 8 for winding is arranged in the middle of the right side of the printing machine housing 1 and is rotated by a shaft. The side wall width of the winding reel 8 is relatively wide and can extend to the inner wall of the printing machine housing 1, so as to guide the waste paper strip 5.

The waste paper strip 5 is wound and fixed on the winding disk 1 6 , and the waste paper strip 5 is closely attached to the baffle plate of the winding disk 2 8 to achieve a supporting effect.

The lateral moving mechanism 2 includes a bracket 21 fixed on the upper end of the printer housing 1, and also includes slide bars 23 fixed on both ends of the bracket 21. When the two sliders 24 are located at the outermost side of the slide bars 23, the blade 37 is in contact with the inner wall of the printer housing 1. This arrangement is suitable for small-scale cutting of the full printing of the main paperboard 4. The two sliders 24 slide through the two ends of the slide bar 23 respectively, and the ends are in contact with the surface of the bracket 21 and can slide. The bracket 21 is located on one side of the slider 24 and a scale line 22 is etched thereon. The slider 24 covers a part of the scale line 22, which is convenient for better reading.

The slider 24 drives the blade 37 to move to the specified position through the connecting frame 31 and the connecting rod 33. The cutting width, that is, the cutting position, is determined according to the scale line 22. The scale line 22 is set to millimeters, and the unit can be set specifically according to the size of the main paperboard 4. The setting is customizable.

A clamping block 26 is provided in the middle of the inner cavity of the two sliders 24 for longitudinal sliding, and can be pressed and fixed with the slide rod 23. The clamping block 26 is made of hard plastic material and has an arc groove adapted to the slide rod 23 at the bottom, which increases the fit and friction, thereby fixing the slider 24 to the slide rod 23. A fastening screw 25 is threadedly provided in the internal thread groove in the middle of the upper end of the two sliders 24, and the lower end of the rod of the fastening screw 25 is in contact with the upper end of the clamping block 26 and can rotate. The fastening screw 25 and the adjustment screw 331 are preferably hexagonal screws.

The two sliders 24 are moved on the slide bar 23 . Since the sliders 24 are in close contact with the bracket 21 , the sliders 24 will not rotate and can be moved to any position as needed.

The cutting mechanism 3 includes a connecting frame 31 fixedly mounted on one side of the two sliders 24, a connecting rod 33 is rotatably arranged in an opening at one end of the connecting frame 31 through a rotating shaft, and the connecting rod 33 can rotate 180 degrees in the opening at one end of the connecting frame 31, so that the blade 37 can be located at a specified position and the angle between the blade 37 and the main paperboard 4 can be adjusted, and also includes a mounting groove 32 opened on one side of the connecting frame 31, and the mounting groove 32 and the head of the half-thread screw 35 can be set to a hexagonal shape;

The head of the half-thread screw 35 can be inserted into the mounting groove 32 and the half-thread screw 35 can be limited to prevent it from rotating. The threaded end of the half-thread screw 35 that passes through the middle of the connecting rod 33 and one side of the connecting frame 31 in the mounting groove 32 extends out of one side of the connecting frame 31 and is threadedly provided with a locking nut 36. A turning handle is fixed on one side of the locking nut 36 (as shown in Figure 3). The turning handle extends and is higher than the connecting frame 31 for easy rotation. Both sides of the opening at one end of the connecting frame 31 have a certain deformation ability, which is convenient for fixing the connecting rod 33.

The connecting rod 33 is in a freely movable state. When in use, the user picks it up by hand, inserts the T-block 39 of the clamp 38 into the second slot 391 and moves it to the bottom, and then inserts the blade 37 into the slot 332 and locates it between the slot 332 and the clamp 38.

The connecting rods 33 are located inside the connecting frame 31, and rubber pads 34 are glued to the inner walls of the connecting frame 31 on both sides. The rubber pads 34 are flexible rubber. A slot 332 for inserting a blade 37 is provided on the side of the two connecting rods 33 away from the connecting frame 31. The handle of the blade 37 has the same shape as the slot 332. A second card slot 391 is provided on the upper part of the slot 332. A first card slot 390 connected to the second card slot 391 and the slot 332 is provided on one side of the second card slot 391. The second card slot 391 is vertical to the second card slot 391. The width of the second card slot 391 is greater than the width of the T-block 39. The length of the first card slot 390 is greater than the length of the T-block 39.

A T-block 39 fixed to one end of the clamp 38 is detachably inserted inside the second clamping slot 391. The clamp 38 is located in the slot 332 and squeezes the blade 37 to fix it. When fixing, the T-block 39 moves to the bottom of the second clamping slot 391 and then moves to the first clamping slot 390. The connecting rod 33 is located on one side of the clamping plate 38 and is threaded with an adjustment screw 331 for tightening the blade 37. The end of the rod of the adjustment screw 331 abuts against the middle of the surface of the clamp 38. A rubber sheet is glued to the contact surface between the clamp 38 and the handle of the blade 37 to increase resistance and firmness.

The connecting rod 33 is in a freely movable state. When in use, the user picks it up with his hand, inserts the T-block 39 of the splint 38 into the second slot 391 and moves it to the bottom, then inserts the blade 37 into the slot 332 and locates it between the slot 332 and the splint 38. Then, the user pushes the splint 38 by rotating the adjustment screw 331 to move the T-block 39 into the first slot 390. A limiting groove can also be provided in the first slot 390 to limit the T-block 39, so that the splint 38 is connected to the connecting rod 33. Since this structure is a common structure, it will not be described in detail (not shown in the figure).

The guide roller inside the printing machine housing 1 is provided with a printed main paperboard 4, and the main paperboard 4 is cut by the blade 37 near the printing completed position. The main paperboard 4 includes a printing position and a waste paper strip 5, and the waste paper strip 5 is a blank position that has not been printed. The waste paper strip 5 is wound and rolled on the winding reel 1 6. The two winding positions of the winding reel 1 6 correspond to the baffle of the winding reel 2 8 to avoid the waste paper strip 5 from being excessively offset and causing poor winding.

The user needs to wind and fix the printing part of the main paperboard 4 on the winding reel 2 8, then the blade 37 performs preliminary cutting and winds the waste paper strip 5 on the winding reel 1 6, and the waste paper strip 5 is tightly attached to the baffle of the winding reel 2 8 to achieve a supporting effect. It should be noted that the rotation of the winding reel 1 6 and the winding reel 2 8 can make the printing part and the waste paper strip 5 synchronously wound, and this process requires customized adaptation.

A slot 7 for carrying the central rotating shaft of the winding reel 6 is provided on the right side of the printer housing 1 , and the upper end of the slot 7 is an open mouth for facilitating the loading of the winding reel 6 .

The device is also provided with a driving device for driving the winding disk 1 6 and the winding disk 2 8 to rotate, and a correcting device for preventing the main paperboard 4 from moving and deviating. The driving device, the correcting device and the printing device are all existing technologies and will not be described in detail. If the main paperboard 4 deviates, the cutting of the main paperboard 4 may fail.

Principle and effect of the utility model:

When using the device for cutting, first, the user will calculate the cutting position of the main paperboard 4 according to the printing surface and the reserved blank size. When the position is determined, the user moves the two sliders 24 on the slide bar 23. The sliders 24 drive the blades 37 to move to the specified position through the connecting frame 31 and the connecting rod 33. Then, the fastening screws 25 push the clamping block 26 to move downward and contact and clamp with the slide bar 23, so that the two sliders 24 can be firmly fixed on the slide bar 23. The user can judge the cutting width, that is, the cutting position, according to the scale lines 22.

Under normal circumstances, the connecting rod 33 is in a freely movable state. When in use, the user picks it up with his hand, inserts the T-block 39 of the splint 38 into the second slot 391 and moves it to the bottom, then inserts the blade 37 into the slot 332 and locates it between the slot 332 and the splint 38, then rotates the adjustment screw 331 to push the splint 38, so that the T-block 39 moves into the first slot 390, so that the splint 38 is connected to the connecting rod 33.

After the blade 37 is inserted and fixed, the user first moves the connecting rod 33 so that the head of the blade 37 cuts and penetrates both sides of the main paperboard 4 and makes it located at a suitable angle;

Then, the user rotates the locking nut 36. As the locking nut 36 continues to rotate, it contacts the connecting frame 31 and causes compression to deform one side of the connecting frame 31. At the same time, the rubber pad 34 is squeezed to deform it, thereby fixing the connecting rod 33.

Before cutting and reeling, the printed portion of the main paperboard 4 is wound and fixed on the reel 2 8 , and then the blade 37 performs preliminary cutting, and the waste paper strip 5 is wound and fixed on the reel 1 6 .

In summary, the device is configured to directly cut the blank positions of the plastic film or paper during printing and recycle the blank positions separately without adding a cutting process later, thereby effectively reducing the production cost and production efficiency of the factory.
