Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to an easily adjustable paper slitter and its accessories. Background Art

[0002] In industries such as papermaking and printing and packaging, a paper slitter is the core equipment for realizing the standardized production of paper. Through the collaborative operation of multiple components such as a transmission system, a frame, and a tension control device, a whole roll of raw paper is cut into finished paper of a fixed size to meet the needs of different product packaging and printing. A cutting knife is provided on the frame. As the cutting knife cuts the raw paper, the cutting knife rubs against the paper for a long time, and it is very easy to wear and become dull. After the cutting knife wears, the resistance in the paper slitting process increases, the cutting accuracy drops significantly, and the phenomenon that the paper cannot be completely cut off often occurs, resulting in an increase in the defective rate.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN205835512U discloses a paper slitter that is convenient for replacing the cutting knife. In the disclosed document, by setting a flipping conveying frame, after the flipping conveying frame flips, an operation cavity for workers to replace the cutting tool is formed at the position of the corresponding flipping conveying frame on the paper conveying platform. A standing footrest is provided at the middle waist position of the operation cavity to achieve the purpose of facilitating the operation of workers when replacing and maintaining the cutting knife, and at the same time improve the work efficiency.

[0004] However, when replacing and maintaining the cutting knife, it is necessary to stop the machine first. After the cutting knife is replaced, the position of the cutting knife on the bracket may change slightly. At this time, it is necessary to reposition the cutting position of the cutting knife and the paper to ensure the accuracy of the paper cutting size. However, the process of repositioning the cutting knife is complex and cumbersome, involving multiple parameter calibrations, which takes a long time, greatly increasing the labor cost and time cost, and seriously delaying the production cycle.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "below", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0032] Such as Figures 1 to 8As shown in the figure, an easily adjustable accessory for a paper slitter provided by an embodiment of the present invention includes a bracket 110, a fixed shaft 130, a guide rail 150, and an adjusting member.

[0033] A plurality of mutually parallel tension rollers 120 are rotatably arranged on the bracket 110. The heights of the plurality of tension rollers 120 on the bracket 110 are different. The paper is arranged to bypass the plurality of tension rollers 120. The plurality of tension rollers 120 can tension the paper on the bracket 110, and the paper can maintain a tensioned state and move on the bracket 110 along a fixed movement trajectory.

[0034] The fixed shaft 130 is fixedly connected to the bracket 110. The fixed shaft 130 is arranged parallel to the tension roller 120. The fixed shaft 130 is arranged below the paper. A plurality of first cutting rings 140 are arranged on the fixed shaft 130. The plurality of first cutting rings 140 are evenly distributed along the axial direction of the fixed shaft 130. The plurality of first cutting rings 140 are all rotatably connected to the fixed shaft 130. The distance between two adjacent first cutting rings 140 is determined by the width of the produced paper strips, so that the distance between two adjacent first cutting rings 140 is equal to the width of the paper strips after paper slitting.

[0035] The guide rail 150 is fixedly connected to the bracket 110. A plurality of guide rails 150 are provided. The plurality of guide rails 150 are all arranged above the paper. The number of the guide rails 150 is equal to the number of the first cutting rings 140, so that each guide rail 150 corresponds to a first cutting ring 140. The plurality of guide rails 150 are evenly spaced along the extending direction of the fixed shaft 130. Each guide rail 150 is arranged directly above a first cutting ring 140. A second cutting ring 160 and a third cutting ring 170 are arranged on each guide rail 150. The second cutting ring 160 and the third cutting ring 170 can both rotate in the guide rail 150 and can both slide along the guide rail 150. In the initial state, the second cutting ring 160 is directly above the first cutting ring 140. The second cutting ring 160 can cooperate with the first cutting ring 140 to cut the paper. At this time, the third cutting ring 170 is in an idle state.

[0036] The adjusting member is used to adjust the cooperation between the third cutting ring 170 and the first cutting ring 140 to cut the paper when the adjacent two strips of paper cannot be completely disconnected after the second cutting ring 160 and the first cutting ring 140 cut the paper. Specifically, when the second cutting ring 160 becomes dull after being used for a period of time, and the second cutting ring 160 and the first cutting ring 140 cannot completely cut the paper, that is, the adjacent two strips of paper are stuck together. At this time, the adjusting member adjusts the second cutting ring 160 and the third cutting ring 170 to slide on the guide rail 150 at the same time. The second cutting ring 160 gradually disengages from the cooperation with the first cutting ring 140, so that the second cutting ring 160 changes to an idle state, and the third cutting ring 170 slides directly above the first cutting ring 140. The third cutting ring 170 gradually cooperates with the first cutting ring 140 to cut the paper. During this process, the paper moves on the bracket 110 at a constant speed, so as to ensure that the speed of paper segmentation remains stable.

[0037] An easily adjustable paper cutting machine accessory of the present invention places the uncut paper on the bracket 110. By arranging a plurality of tension rollers 120 on the bracket 110, the paper is in a tensioned state on the bracket 110. The fixed shaft 130 is arranged below the paper, and then a plurality of first cutting rings 140 are below the paper. A plurality of guide rails 150 are arranged on the bracket 110, and the guide rails 150 are arranged above the paper. A second cutting ring 160 and a third cutting ring 170 are arranged on each guide rail 150. Both the second cutting ring 160 and the third cutting ring 170 are above the paper. In the initial state, the second cutting ring 160 and the first cutting ring 140 are in a cooperative state, and the third cutting ring 170 is in an idle state. After the second cutting ring 160 wears and becomes dull, the second cutting ring 160 and the first cutting ring 140 cannot completely cut the paper, resulting in a situation where the adjacent two strips of paper cannot be completely disconnected. At this time, the adjusting member adjusts the second cutting ring 160 and the third cutting ring 170 to slide on the guide rail 150 at the same time. The second cutting ring 160 gradually disengages from the cooperation with the first cutting ring 140, and the third cutting ring 170 gradually cooperates with the first cutting ring 140. During this process, there is no need to stop the machine, ensuring that the overall segmentation speed remains stable, thereby preventing the production efficiency from decreasing.

[0038] In one embodiment, the adjusting member includes a detecting unit and an adjusting unit. The detecting unit is configured to detect the state of two adjacent strips of paper after being cut by the second cutting ring 160 and the first cutting ring 140 together. Among them, after the paper is cut, the two adjacent strips of paper have a completely separated state and an incompletely separated state. After the second cutting ring 160 is used for a long time, the sharpness of the second cutting ring 160 will decrease, making the second cutting ring 160 blunt. After the second cutting ring 160 becomes blunt, after the second cutting ring 160 and the first cutting ring 140 cut the paper together, the two adjacent strips of paper are likely to be in an incompletely separated state. The adjusting unit is used to adjust the second cutting ring 160 and the third cutting ring 170 to slide along the guide rail 150 simultaneously. In the initial state, the second cutting ring 160 is directly above the first cutting ring 140. After the second cutting ring 160 becomes blunt, the adjusting unit adjusts the second cutting ring 160 and the third cutting ring 170 to slide along the guide rail 150 simultaneously. The third cutting ring 170 moves to directly above the first cutting ring 140, and the second cutting ring 160 changes to an idle state, so that the third cutting ring 170 cooperates with the first cutting ring 140 to ensure that the cutting speed of the paper remains stable.

[0039] In one embodiment, the detecting unit includes a detecting rod 210 and a mounting block 220. The first cutting ring 140 includes a first half-ring and a second half-ring. The first half-ring and the second half-ring are coaxially arranged at intervals. The first half-ring and the second half-ring have the same size. Both the first half-ring and the second half-ring can rotate on the fixed shaft 130. The distance between the first half-ring and the second half-ring is equal to the thickness in the axial direction of the second cutting ring 160 or the third cutting ring 170, ensuring that both the second cutting ring 160 or the third cutting ring 170 can enter between the first half-ring and the second half-ring. When the second cutting ring 160 or the third cutting ring 170 enters between the first half-ring and the second half-ring, as the paper moves on the bracket 110, the paper is cut. The mounting block 220 is fixedly connected to the fixed shaft 130. The mounting block 220 is arranged between the first half-ring and the second half-ring. One end of the detecting rod 210 is rotatably connected to the mounting block 220. In the initial state, the detecting rod 210 is in an inclined state. The end of the detecting rod 210 away from the mounting block 220 can extend above the strip of paper through the gap between two adjacent strips of paper. After the second cutting ring 160 and the first cutting ring 140 cut the paper, if the two adjacent strips of paper cannot be completely disconnected, the connection between the two adjacent strips of paper can squeeze the detecting rod 210, causing the detecting rod 210 to deflect on the mounting block 220. At this time, the staff can timely discover the situation that the second cutting ring 160 becomes blunt.

[0040] In one embodiment, the adjusting unit includes a traction member and a stop rod 240. Two abutting mounting seats are slidably arranged on the guide rail 150. The second cutting ring 160 is rotatably connected to one mounting seat, and the third cutting ring 170 is rotatably connected to the other mounting seat. Further, for the convenience of describing the two mounting seats, the mounting seat connected to the second cutting ring 160 is defined as the first mounting seat 250, and the mounting seat connected to the third cutting ring 170 is defined as the second mounting seat 260. In the initial state, the second mounting seat 260 is at one end of the guide rail 150, and the first mounting seat 250 is in the middle of the guide rail 150. At this time, the second cutting ring 160 is directly above the first cutting ring 140. The traction member is used to traction the second mounting seat 260 to slide along the guide rail 150. In this embodiment, the traction member includes a traction spring 230. One end of the traction spring 230 is fixedly connected to the end of the guide rail 150, and the other end of the traction spring 230 is fixedly connected to the second mounting seat 260. The middle of the traction spring 230 straddles the first mounting seat 250. In the initial state, the traction spring 230 is in a stretched state. Under the action of the restoring force of the traction spring 230, the second mounting seat 260 has a tendency to slide along the guide rail 150. There are two stop rods 240, and each stop rod 240 is fixedly connected to a mounting seat. Initially, it is set that the stop rod 240 connected to the first mounting seat 250 can abut against the detection rod 210. When the detection rod 210 does not rotate on the mounting block 220, the detection rod 210 can prevent the first mounting seat 250 from sliding along the guide rail 150, thereby preventing the traction spring 230 from traction the second mounting seat 260 to slide along the guide rail 150. After the second cutting ring 160 and the first cutting ring 140 cut the paper, if the adjacent two strips cannot be completely disconnected, the connection part between the adjacent two strips can squeeze the detection rod 210, so that the detection rod 210 deflects on the mounting block 220. After the detection rod 210 rotates, the detection rod 210 can disengage from abutting against the stop rod 240 connected to the first mounting seat 250. Under the traction of the traction spring 230, the second mounting seat 260 gradually slides along the guide rail 150, so that the third cutting ring 170 moves to directly above the first cutting ring 140, so that the third cutting ring 170 contacts the first half ring and the second half ring, and the second cutting ring 160 changes to the idle state, and the second cutting ring 160 disengages from contacting the first half ring and the second half ring. The staff can repair or replace the second cutting ring 160 in the idle state.

[0041] In one embodiment, as shown in the attached Figure 8 figure, the upper end surface of the detection rod 210 is set as an arc surface. When there is a connection state between adjacent two strips, it is ensured that the connection position of the adjacent two strips can smoothly squeeze the detection rod 210, so that the detection rod 210 rotates on the mounting block 220.

[0042] In one embodiment, when the second cutting ring 160 or the third cutting ring 170 cooperates with the first cutting ring 140 to cut the paper, the burrs generated at the edges of adjacent two strips of paper are in a downward inclined state. As shown in the appended Figure 8 figure, it is set that the thickness of the lower part of the detection rod 210 is greater than that of the upper part. The detection rod 210 can extend above the strip of paper through the gap between adjacent two strips of paper. By setting the thickness of the detection rod 210, when the detection rod 210 moves relative to the strip of paper, the detection rod 210 can flick the burrs at the edge of the strip of paper upward to ensure that the burrs at the edge of the strip of paper are in a neat state.

[0043] In one embodiment, a plurality of balls 270 are arranged at one end of the detection rod 210 away from the mounting block 220. By arranging the balls 270 at the end of the detection rod 210, the friction between the detection rod 210 and the stop rod 240 is reduced. When the detection rod 210 abuts against the stop rod 240 and the adjacent two strips of paper are not completely separated, the adjacent two strips of paper can squeeze the detection rod 210, so that the detection rod 210 can rotate smoothly on the mounting block 220.

[0044] In one embodiment, there is a reset torsion spring between the detection rod 210 and the mounting block 220. After the detection rod 210 rotates on the mounting block 220, the reset torsion spring can drive the detection rod 210 to reset on the mounting block 220. The reset torsion spring has an inner end and an outer end. The inner end of the reset torsion spring is fixedly connected to the mounting block 220, and the outer end of the reset torsion spring is fixedly connected to the detection rod 210. In the initial state, the reset torsion spring is in an unloaded state. After the detection rod 210 is squeezed by the adjacent two strips of paper, the detection rod 210 rotates on the mounting block 220, and the reset torsion spring gradually stores energy. When the third cutting ring 170 moves above the first cutting ring 140, the reset force of the reset torsion spring gradually drives the detection rod 210 to reset. During the movement of the third cutting ring 170 along the guide rail 150, the third cutting ring 170 can cut the adjacent two strips of paper that are not completely separated, ensuring that the detection rod 210 can reset smoothly on the mounting block 220.

[0045] In one embodiment, the guide rail 150 is set to be arc-shaped. Initially, the second cutting ring 160 is set directly above the fixed shaft 130. During the process of the third cutting ring 170 sliding along the guide rail 150, the third cutting ring 170 can cut the unbroken area of the adjacent two strips of paper. Further, the diameter of the third cutting ring 170 is equal to the diameter of the second cutting ring 160. When both the second cutting ring 160 and the third cutting ring 170 can enter the preset depth between the first half ring and the second half ring, by adjusting the radian of the guide rail 150, it is ensured that during the process of the third cutting ring 170 sliding along the guide rail 150, the third cutting ring 170 can cut the unbroken area of the adjacent two strips of paper, thereby ensuring that the detection rod 210 can reset smoothly on the mounting block 220.

[0046] In one embodiment, a driving roller 310 and a driving motor are provided on the bracket 110. The driving roller 310 is rotatably connected to the bracket 110. The driving roller 310 is arranged parallel to the fixed shaft 130. A plurality of driving sleeves 320 are provided on the driving roller 310. Each driving sleeve 320 can drive a first cutting ring 140. The driving motor is fixedly connected to the bracket 110. The driving motor is used to drive the driving roller 310 to rotate. Through the transmission of the driving sleeve 320, the plurality of first cutting rings 140 rotate on the fixed shaft 130 simultaneously.

[0047] In one embodiment, each driving sleeve 320 includes a first sleeve body and a second sleeve body. The first sleeve body and the second sleeve body are fixedly connected at intervals. Locking screws are threadedly connected to both the first sleeve body and the second sleeve body. The locking screws can fix the first sleeve body and the second sleeve body on the driving roller 310. The first sleeve body is used to limit the sliding of the first half-ring on the fixed shaft 130, and the second sleeve body is used to limit the sliding of the second half-ring on the fixed shaft 130. When it is necessary to adjust the width of the paper strip, the distance between two adjacent driving sleeves 320 can be adjusted. Under the action of the first sleeve body and the second sleeve body, the first half-ring and the second half-ring slide on the fixed shaft 130 simultaneously.

[0048] An easily adjustable paper cutting machine includes an easily adjustable paper cutting machine accessory, and further includes an unwinding roller and a winding roller. The unwinding roller and the winding roller are both rotatably connected to the bracket 110. Uncut paper is wound on the unwinding roller, and the winding roller is used to wind the cut paper strips. A driving motor is provided on the bracket 110. The driving motor is used to drive the winding roller to rotate. Under the action of the driving motor, the winding roller winds the paper strips, and the unwinding roller unwinds the paper passively, so as to ensure that the paper moves on the bracket 110 along a fixed movement track.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
