Description

Technical Field

[0001] This utility model relates to the field of roll paper slitting technology, and in particular to a tension adjustment and conveying device for roll paper slitting machines. Background Technology

[0002] Roll paper is a single sheet of paper wound into a cylindrical shape. Compared to sheet paper, roll paper saves more space and reduces overall costs during production and transportation.

[0003] When paper is used in paper mills or printing plants, slitting machines are typically used to cut rolls of paper into sheets of equal length. Currently, in the process of slitting rolls of paper, the roll is usually pulled out first, then conveyed by a conveyor roller, then cut using a cutting tool, and the cut sheets are stacked before being transferred to subsequent processing steps. However, because the roll of paper generates internal stress during transport after winding, the release of this stress after cutting can cause the paper to curl at the edges. This not only affects the stacking effect of the subsequent sheets but also causes inconvenience to subsequent processing. In addition, during the conveying process of the roll, relying solely on the conveyor rollers can easily lead to uneven tension distribution in the paper, thus affecting the accuracy of paper slitting.

[0004] In summary, this application proposes a tension adjustment and transmission device for a roll slitting machine, which improves the aforementioned technical problems. Utility Model Content

[0005] To overcome the problem that stress release after cutting roll paper can cause paper curling, which not only affects the stacking of subsequent paper but also causes inconvenience to subsequent processing, this utility model provides a tension adjustment and conveying device for a roll slitting machine.

[0006] Technical Solution: The tension adjustment and conveying device of the roll slitting machine includes a conveyor table and a feeding unit; the conveyor table is connected to the feeding unit for conveying paper; it also includes a slide rail, an electric drive block, an electric turntable, a clamping roller one, a clamping roller two, a motor, an electric slider, and a cutting unit; a slide rail is fixedly connected to the front and rear sides of the conveyor table; several electric drive blocks are slidably connected to each slide rail; each electric drive block is fixedly connected to an electric turntable; an electric slider is slidably connected to the rotating part of each electric turntable; each pair of corresponding electric sliders is jointly fixedly connected to a clamping roller one; each electric turntable is rotatably connected to a clamping roller two, and the clamping roller two is located below the clamping roller one; each electric turntable is fixedly connected to a motor, and the motor output shaft is fixedly connected to the clamping roller two.

[0007] To further explain, the feeding unit includes support rollers, guide rollers, and conveying rollers; the conveyor table is rotatably connected to two symmetrically distributed support rollers; the conveyor table is rotatably connected to several guide rollers, and the guide rollers are connected to an external power supply; the conveyor table is rotatably connected to several conveying rollers, and the conveying rollers are connected to an external power supply.

[0008] To further explain, the cutting unit includes a fixed plate, electric push rods, and a cutter; the conveyor table is fixedly connected to the fixed plate; the fixed plate is fixedly connected to several electric push rods; and the telescopic parts of all the electric push rods are jointly fixedly connected to a cutter for cutting paper.

[0009] To further explain, several electrically driven blocks are equidistantly distributed on the slide rail.

[0010] To further clarify, the length of the second clamping roller is set to 15cm-25cm.

[0011] To further explain, the clamping rollers have chamfers at both ends.

[0012] To further explain, the ends of the support rollers are designed to be conical.

[0013] The beneficial effects of this utility model are as follows:

[0014] The conveyed paper roll is tightened by moving the electric drive block, thereby releasing the internal stress of the paper roll to a certain extent and reducing the possibility of paper rollback during subsequent cutting. The tension of the paper roll is adjusted by controlling the speed of the electric drive block, so that the pulled-out paper roll is always in a taut state to facilitate subsequent cutting.

[0015] By using three electrically driven blocks to move synchronously and clamp the paper, and then continue to pull it out to the left, continuous and uninterrupted pulling and cutting are achieved. This keeps the conveyed paper roll in a taut state, reducing the possibility of it rewinding after cutting and improving the accuracy of paper cutting. Attached Figure Description

However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0023] Example 1

[0024] The tension adjustment and conveying device of the roll slitting machine, refer to Figures 1-5 As shown, it includes a conveyor table 1 and a feeding unit; the conveyor table 1 is connected to the feeding unit.

[0025] It also includes a slide rail 5, an electric drive block 6, an electric turntable 7, a clamping roller 1 8, a clamping roller 2 9, a motor 10, an electric slider 11, and a cutting unit; a slide rail 5 is fixedly connected to the front and rear sides of the conveyor table 1; three electric drive blocks 6 are slidably connected to each slide rail 5; an electric turntable 7 is fixedly connected to each electric drive block 6; an electric slider 11 is slidably connected to the rotating part of each electric turntable 7; a clamping roller 1 8 is fixedly connected to each pair of corresponding electric sliders 11; a clamping roller 2 9 is rotatably connected to each electric turntable 7, and the clamping roller 2 9 is located below the clamping roller 1 8. The paper being conveyed is clamped and pulled out by the clamping roller 1 8 and the clamping roller 2 9, thereby adjusting the tension of the paper for cutting; a motor 10 is fixedly connected to each electric turntable 7, and the output shaft of the motor 10 is fixedly connected to the clamping roller 2 9.

[0026] The feeding unit includes a support roller 2, a guide roller 3, and a conveying roller 4; two symmetrically distributed support rollers 2 are rotatably connected to the right side of the conveying platform 1; several guide rollers 3 are rotatably connected to the conveying platform 1, and the guide rollers 3 are connected to an external power supply; several conveying rollers 4 are rotatably connected to the conveying platform 1, and the conveying rollers 4 are connected to an external power supply.

[0027] The cutting unit includes a fixed plate 101, electric push rods 102 and a cutter 103; the conveyor table 1 is fixedly connected to the fixed plate 101; the fixed plate 101 is fixedly connected to three electric push rods 102; the telescopic parts of all the electric push rods 102 are jointly fixedly connected to a cutter 103.

[0028] The three electric drive blocks 6 are equidistantly distributed on the slide rail 5, which facilitates the continuous pulling of paper by the clamping roller 8 and the clamping roller 9, enabling uninterrupted operation.

[0029] The length of clamping roller 29 is set to 15cm-25cm, which facilitates the quick release of clamping roller 29 from the paper after the paper is cut.

[0030] The end of the clamping roller 29 is chamfered to facilitate the rotation of the clamping roller 29 into the bottom of the paper.

[0031] The end of the support roller 2 is set in a pointed cone shape to facilitate clamping and fixing the roll of paper.

[0032] The paper slitting operation is as follows: The roll is manually clamped and fixed using two cone-shaped support rollers 2. Then, the end of the roll is manually pulled out and wound sequentially through several guide rollers 3, and then through the conveyor rollers 4, as shown below. Figure 2As shown, the paper roll is pulled out and conveyed to the left by controlling the rotation of the guide roller 3 and the conveying roller 4. During the conveying process, the electric push rod 102 is timed to drive the cutter 103 downward to cut the paper roll into sheets. Finally, the conveying roller 4 conveys the cut sheets to the left for subsequent stacking and processing. However, because the paper roll generates internal stress during transport after winding, the release of this stress after cutting can cause the paper to curl at the edges. This not only affects the subsequent stacking effect of the paper but also causes inconvenience to subsequent processing. Therefore... The paper roll is manually guided through the right-side conveyor roller 4, then passed between clamping roller 8 and clamping roller 9. The electric slider 11 is controlled to move clamping roller 8 downwards, working in conjunction with clamping roller 9 to hold the paper roll end. Subsequently, the guide roller 3 and conveyor roller 4 are controlled to rotate and convey the paper roll, while simultaneously the electric drive block 6 moves clamping roller 8 and clamping roller 9 to the left along the slide rail 5. The three electric drive blocks 6 are equidistantly distributed on the slide rail 5. When the first electric drive block 6 moves the paper roll to the left, the second electric drive block 6 is simultaneously controlled to move along the slide rail 5. The second electric drive block 6 moves to the left of the right conveyor roller 4. During the movement of the second electric drive block 6, the electric turntable 7 on the second electric drive block 6 drives the clamping roller 1 8 and clamping roller 2 9 to rotate, ensuring that clamping roller 1 8 is always above clamping roller 2 9. The motor 10 is then controlled to drive clamping roller 2 9 to rotate 90 degrees, causing clamping roller 2 9 to avoid the paper roll being conveyed to the left. As the second electric drive block 6 continues to move, it stops moving when clamping roller 1 8 contacts the upper surface of the conveyed paper roll. Then, the motor 10 is controlled to drive clamping roller 2 8 to rotate. 9. Rotate to reset, so that the conveyed roll of paper is positioned between the clamping roller 8 and the clamping roller 9 on the second electric drive block 6. At this time, the clamping roller 8 and the clamping roller 9 on the first electric drive block 6 clamp the roll of paper and move it to the left. The movement of the first electric drive block 6 tightens the conveyed roll of paper, thereby releasing the internal stress of the roll of paper to a certain extent, reducing the possibility of paper rewinding during subsequent cutting. By controlling the movement speed of the first electric drive block 6, the tension of the roll of paper is adjusted so that the pulled roll of paper is always in a taut state, which is convenient for subsequent cutting.

[0033] When the length of the pulled-out paper roll reaches the preset cutting length, the electric push rod 102 is then controlled to drive the cutter 103 downwards to cut the paper roll. Simultaneously, the electric slider 11 on the second electric drive block 6 is controlled to drive the clamping roller 8 downwards to clamp and fix the conveyed paper roll. The second electric drive block 6 is also controlled to begin moving to the left, so that after cutting, the end of the paper roll is clamped by the second electric drive block 6 and pulled further to the left. During the process of the second electric drive block 6 clamping and pulling out the paper roll, the same operation is repeated to control the... Three electric drive blocks 6 move to achieve continuous and uninterrupted pulling and cutting, keeping the conveyed paper roll taut at all times, reducing the possibility of rewinding after cutting and improving the accuracy of paper cutting. The cut paper is clamped by the first electric drive block 6 and moved to the left. When the paper comes into contact with the left conveyor roller 4, the electric slider 11 on the first electric drive block 6 is controlled to move the clamping roller 8 upward to reset and stop clamping the paper. Finally, the cut paper is conveyed to the left by the left conveyor roller 4 and then stacked and processed.
