Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, and in particular to an anti-rewinding label slitting machine. Background Art

[0002] Labels are used to mark product targets and categories or contents, like keywords for targets, which are tools for you and others to find and locate targets. Labels are made on a piece of paper with a certain width. After the production is completed, the paper needs to be cut according to the size of the label and rewound for easy packaging and sale.

[0003] The cutting of labels requires the use of a slitting machine. The original wide label roll passes through the combing mechanism and the slitting mechanism, and then is slit by the slitting mechanism and then rewound by the winding mechanism, thereby completing the label slitting operation.

[0004] The winding mechanism used in the existing label slitting machine has multiple groups of parallel windings and multiple groups of staggered windings. However, no matter which winding method is used, as the label after slitting is wound, the winding diameter of the winding roller and the label is increasing. When the speed of the driving motor remains unchanged, the length of the wound label increases with each rotation of the winding roller. This causes the winding speed to increase continuously during the slitting process. Due to the excessively fast winding speed, the friction generated between the label paper and the equipment during the conveying process also increases. At the same time, the feed roller for conveying the label decreases in diameter as the number of labels wound on the surface decreases. This causes the feed roller to need to rotate faster than the winding roller to keep up with the winding speed of the winding roller. Otherwise, the label will be pulled when the winding roller is wound, which can easily cause the label to deform and wrinkle, causing damage to the label, thereby resulting in a decrease in slitting quality and affecting the production quality of the label. Summary of the invention

[0021] Beneficial Effects

[0022] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0023] 1. The present invention adopts a driving roller friction-driven winding roller group to rotate and wind. When the driving roller rotates, it contacts the winding roller group and drives the winding roller group to rotate under the action of friction, so that the label is wound on the winding roller group. As the diameter of the cylinder formed by the winding roller group and the wound label increases, the diameter of the winding roller group gradually becomes larger than the driving roller group, so that the driving roller group needs to rotate multiple circles for one circle of the winding roller group. When the speed of the driving motor remains unchanged, the speed of the winding roller group continues to decrease. The increasing winding length is compensated by reducing the winding speed of the winding roller group, thereby maintaining the stable transportation of the label to the greatest extent, so that the friction force during the label transportation process remains stable, the pulling of the label is reduced, and the quality of the slitting operation is guaranteed.

[0024] 2. The present invention utilizes that when the label is subjected to a pulling force, the sorting roller is subjected to a force toward the lower left, thereby driving the sorting roller to move toward the lower left. At this time, the sorting roller squeezes the airbag column, thereby squeezing the air in the airbag column into the interior of the sorting roller. Under the action of air pressure, the lubricating oil inside the sorting roller is squeezed out from the liquid outlet through the pressure valve, and the lubricating oil is evenly applied to the bottom of the label and the surface of the sorting roller in coordination with the rotation of the sorting roller, thereby reducing the friction between the sorting roller and the label, thereby making the label conveying smoother, further reducing the pulling force on the label, and ensuring the label slitting quality.

[0025] 3. After the feed roller with the label wound on it is installed on the second bracket of the present invention, the feed roller slides to the rightmost side in the second slide groove through the second slider under the action of gravity. At this time, the second spring is stretched. As the slitting operation proceeds, the number of labels on the feed roller continues to decrease, thereby causing the weight of the feed roller to continue to decrease. At this time, the second spring returns to its original position and contracts, pulling the second slider to slide along the second slide groove, driving the feed roller to gradually move to the left, thereby gradually shortening the distance between the feed roller and the winding roller group, thereby shortening the conveying distance of the label, further reducing the pulling force of the winding roller group on the label when winding, and ensuring the label slitting quality.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example:

[0038] See also Figure 1 , Figure 2 , Figure 5 and Figure 7 , an anti-rewinding label slitting machine, comprising a frame 1, a first bracket 2 is fixedly connected to the upper left side of the frame 1, and a winding speed reduction mechanism 3 is provided between the first bracket 2 and the upper left side of the frame 1;

[0040] A second bracket 4 is fixedly connected to the right side of the upper end of the frame 1, and a feeding roller 5 is rotatably connected to the right end of the second bracket 4. A slitting mechanism 7 is provided in the middle of the upper end of the frame 1, and a sorting mechanism 6 is provided on both sides of the slitting mechanism 7 at the upper end of the frame 1. The sorting mechanism 6 includes two sorting rollers 62 respectively located on both sides of the slitting mechanism 7, and a turntable 61 is installed at the end of each of the sorting rollers 62. The turntable 61 is rotatably installed on the upper end of the frame 1;

[0041] The slitting mechanism 7 comprises a slitting roller 71 rotatably connected to the middle of the upper end of the frame 1, and a slitting disc 72 is slidably sleeved on the surface of the slitting roller 71, and a slitting cover 73 is sleeved on the outer side of the slitting roller 71 at the upper end of the frame 1, and a glue removal seat 74 is slidably connected to the inside of the slitting cover 73, and a glue removal groove 75 is opened in the middle of the glue removal seat 74;

[0042] A liquid storage chamber 10 is provided at the upper end of the inner part of the frame 1, and a piston plate 11 is slidably connected to one side of the inner part of the liquid storage chamber 10, a traction rope 12 is fixedly connected between the piston plate 11 and the first slider 34, a liquid guide tube 13 is fixedly connected between the liquid storage chamber 10 and the slitting cover 73, the slitting disk 72 includes a positioning disk 721 and a slitting knife 722, and the slitting knife 722 is movably connected to the inner edge of the positioning disk 721, a coil spring 76 is fixedly connected between the inner wall of the slitting knife 722 and the slitting roller 71, a liquid spray port 78 is provided on one side of the inner wall of the glue removal seat 74, and a scraping groove 77 is fixedly connected to the other side of the inner part of the glue removal seat 74;

[0043] The minimum sliding resistance between the winding speed reduction mechanism 3 and the first bracket 2 is greater than the friction force between the driving roller 31 and the winding roller group 35 .

[0044] Specifically, firstly, the feeding roller 5 with the label wound on it is installed on the second bracket 4, and then one end of the label is dragged so that the label passes through the sorting mechanism 6 and the slitting mechanism 7 and is fixed on the winding roller group 35, and then the driving motor 32 is started, and the driving motor 32 drives the driving roller 31 to rotate. When the driving roller 31 rotates, it contacts the winding roller group 35 and drives the winding roller group 35 to rotate under the action of friction, so that the label is wound on the winding roller group 35. During the winding process, the label is continuously transported from the right feeding roller 5 through the sorting mechanism 6 and the slitting mechanism 7 to the left winding roller group 35. During the transportation process, the label contacts and rubs with the sorting roller 62 on the sorting mechanism 6, driving the sorting roller 62 to rotate through the turntable 61, so that the label is smoothed and sorted by the sorting roller 62. The label is prevented from shifting during transportation, and the neat cutting of the label is ensured. At the same time, when the label passes through the slitting mechanism 7, it will contact the slitting disk 72 on the surface of the slitting roller 71 in the slitting mechanism 7, and the slitting disk 72 can be used to slit the label. At the same time, the slitting roller 71 drives the slitting disk 72 to rotate, and the side of the slitting disk 72 that contacts the label during slitting is rotated to the inside of the glue removal groove 75 on the glue removal seat 74, so that the colloid attached to the surface of the slitting disk 72 during slitting is removed. It not only avoids the viscosity of the colloid affecting the slitting of the slitting disk 72, but also reduces the resistance of the viscosity of the colloid to the label being transported, so that the label can be transported normally, and the slitting cover 73 can protect the slitting part to avoid the staff from accidentally touching the slitting disk 72 and being injured, and can also prevent the debris generated during slitting from splashing out.

[0045] In addition, conventional slitting machines all use a driving motor 32 to directly drive the winding roller group 35 to rotate and wind the slit labels. As the labels are slid and conveyed, the number of labels wound on the surface of the winding roller group 35 gradually increases. At this time, the diameter of the cylinder formed by the winding roller group 35 and the wound labels increases. When the speed of the driving motor 32 is inconvenient, the length of the label wound by one circle of the winding roller group 35 increases, thereby speeding up the conveying speed of the label, and further increasing the friction between the label and the sorting mechanism 6, causing the label to be pulled during winding, which can easily cause the label to deform.

[0046] In view of this, the present invention adopts the driving roller 31 to frictionally drive the winding roller group 35 to rotate and wind. When the driving roller 31 rotates, it contacts the winding roller group 35 and drives the winding roller group 35 to rotate under the action of friction, so that the label is wound on the winding roller group 35. As the diameter of the cylinder formed by the winding roller group 35 and the wound label increases, under the action of the resistance force of the driving roller 31, the winding roller group 35 moves to the left along the first slide groove 33 through the first slider 34, while the diameter of the driving roller 31 remains unchanged, and the diameter of the winding roller group 35 continues to increase. At this time, the diameter of the winding roller group 35 gradually becomes larger than the driving roller group 31, so that the driving roller group 31 needs to rotate multiple circles for the winding roller group 35 to rotate one circle. When the rotation speed remains unchanged, the rotation speed of the winding roller group 35 continues to decrease. The winding speed of the winding roller group 35 is reduced to compensate for the increasing winding length, thereby maintaining the stable transportation of the label to the greatest extent, so that the friction force during the label transportation process remains stable, reducing the pulling of the label, and ensuring the quality of the slitting operation. It should be noted that the minimum sliding resistance between the winding deceleration mechanism 3 and the first bracket 2 is greater than the friction force between the driving roller 31 and the winding roller group 35, which can prevent the winding roller group 35 from being displaced after being touched by the driving roller 31 during the winding process, resulting in unstable positioning of the winding roller group 35, and insufficient friction after being released from the driving roller group 31, resulting in the inability to be driven to rotate by the driving roller 31.

[0047] On the basis of the above scheme, since the driving roller 31 needs a certain friction force to drive the winding roller group 35 to rotate, the driving roller 31 is always in a close contact state with the winding roller group 35. Therefore, after the winding is completed, or when the label is cut off midway to replace the winding roller group 35, the tail end of the label will be clamped by the driving roller 31 and the winding roller group 35, thereby preventing the wound label from being unwound;

[0048] In addition, in conjunction with the first slider 34 moving to the left along the first slide groove 33, the first slider 34 will pull the piston plate 11 to slide from right to left inside the liquid storage chamber 10 through the pull rope 12, so that the piston plate 11 is used to introduce the degumming liquid inside the liquid storage chamber 10 into the slitting cover 73 through the liquid guide tube 13 and spray it onto the surface of the slitting knife 722 through the liquid spray port 78 on the inner wall of the degumming seat 74. After entering the degumming groove 75 in the middle of the degumming seat, the slitting knife 722 will be resisted by the scraping groove 77 and move sideways. At this time, under the action of the coil spring 76, the slitting knife 722 is tightly attached to the scraping groove 77, so that the scraping groove 77 is used to scrape off the colloid attached to the slitting knife 722 in conjunction with the rotation of the slitting knife 722, so as to avoid the colloid adhering to the surface of the slitting knife 722, which increases the resistance between the slitting mechanism 7 and the label.

[0049] See also Figure 3 and Figure 6A resistance reducing mechanism 8 is provided between the turntable 61 and the finishing roller 62, and the resistance reducing mechanism 8 includes a first spring 81 which is fixedly connected equidistantly between the inner wall of the turntable 61 and the end of the outer wall of the finishing roller 62, and an air bag column 82 is fixedly connected inside the first spring 81 between the turntable 61 and the finishing roller 62, and the air bag column 82 is communicated with the finishing roller 62, and liquid outlet holes 83 are equidistantly provided on the surface of the finishing roller 62, and the interior of the finishing roller 62 is filled with lubricating oil 84; a pressure valve is provided inside the liquid outlet hole 83, and the opening of the liquid outlet hole 83 is processed by arc-shaped inward concave.

[0050] Specifically, as the winding speed increases, the friction between the label and the collating mechanism 6 increases, so that the label is pulled during winding. At this time, the collating roller 62 is subjected to a force to the lower left under the action of the pulling force, thereby driving the collating roller 62 to move to the lower left. At this time, the collating roller 62 squeezes the airbag column 82, thereby squeezing the air in the airbag column 82 into the interior of the collating roller 62. Under the action of air pressure, the lubricating oil 84 inside the collating roller 62 is squeezed out from the liquid outlet 83 through the pressure valve, and cooperates with the rotation of the collating roller 62. The lubricating oil 84 is evenly applied to the bottom of the label and the surface of the sorting roller 62 to reduce the friction between the sorting roller 62 and the label, thereby making the label conveying smoother, further reducing the pulling force on the label, and ensuring the quality of label slitting. After that, the sorting roller 62 is reset, and the first spring 81 is reset to drive the airbag column 82 to extend to replenish the air pressure for the airbag column 82. It should be noted that the opening of the liquid outlet hole 83 is treated with an arc-shaped concave surface to prevent the label from being scratched by the hole wall of the liquid outlet hole 83 when passing through the surface of the sorting roller 62.

[0051] See also Figure 1-Figure 4 A distance adjusting mechanism 9 is provided between the feed roller 5 and the second bracket 4, and the distance adjusting mechanism 9 includes a second slide groove 91 opened at the upper end of the second bracket 4, and a second slider 92 is slidably connected inside the second slide groove 91, and the two second sliders 92 are rotatably connected to the feed roller 5. A second spring 93 is fixedly connected inside the second slide groove 91 and located on the left side of the second slider 92; the elastic force of the second spring 93 is greater than the sum of the gravity of the feed roller 5 and the friction between the second slider 92 and the second slide groove 91.

[0052] The second spring 93 is then pulled back to move the label roller 5 to the left, thereby gradually shortening the distance between the label roller 5 and the winding roller group 35, and further shortening the conveying distance of the label, thereby further reducing the pulling force of the winding roller group 35 on the label, and ensuring the label slitting quality. It should be noted that the elastic force of the second spring 93 is greater than the sum of the gravity of the label roller 5 and the friction between the second slider 92 and the second slide groove 91, which can ensure that the feed roller 5 can be pulled back to the left along the second slide groove 91 by the second spring 93 after the weight is reduced.

[0053] See also Figure 1-Figure 2 The first slide groove 33 has an air bag 14 fixedly connected to one side of the first slider 34 inside, the upper end of the frame 1 has a nozzle 15 fixedly connected to one side of the driving roller 31, and a conduit 16 fixedly connected between the nozzle 15 and the air bag 14.

[0054] Specifically, the first slider 34 moves to the left along the first slide groove 33. At this time, the first slider 34 will squeeze the airbag bag 14, causing the airbag bag 14 to shrink, thereby squeezing the gas inside the airbag bag 14 through the conduit 16 to the nozzle 15 and being sprayed out by the nozzle 15. The sprayed gas blows to the lubricating surface of the label, thereby utilizing the air flow to accelerate the rapid drying of the lubricating oil on the lubricating surface of the label, thereby avoiding the lubricating oil adhering to the surface of the label, resulting in excessive surface tension of the label, which causes the label to jump during winding and increases the winding resistance of the label, thereby ensuring the quality of label slitting. It should be noted that since the lubricating oil overflows from the liquid outlet 83 and adheres to the surface of the sorting roller 62, the amount of lubricating oil attached to the label after contacting the sorting roller 62 is limited. At the same time, the first slider 34 continues to slide and squeeze the airbag bag 14, so that the gas continues to blow on the lubricating surface of the label, ensuring that the lubricating oil on the surface of the label can be completely dried.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
