Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a packaging bag cutting device. Background Art

[0002] Packaging bags are bags used to package various supplies. They are created to facilitate the transportation and storage of goods during the production and circulation process. They are widely used in daily life and industrial production. The most common packaging bags are plastic packaging bags.

[0003] In the production of packaging bags, the film must go through processes such as copperplate, printing, lamination, aging, bag making and slitting to finally obtain the finished packaging bags. The slitting process is at the end of the process. The corresponding slitting equipment needs to set the predetermined cutting position of the cutting head on the bag body, and use the cutting head to cut the continuous bag body made of wide film into multiple rows of narrow widths.

[0004] In the actual packaging bag slitting process, many packaging bag slitting equipment will face the following problems: if the bag body of the packaging bag is not sufficiently tensioned between the material rollers of the slitting equipment, wrinkles are likely to occur during transportation. Once wrinkles occur, the size of the packaging bag will deviate, affecting the slitting process of the packaging bag. As the slitting operation time increases, the bag body and the material roller will occasionally become loose and wrinkles will occur. Especially for some large-scale packaging bag slitting equipment with high precision requirements, if wrinkles are found in the packaging bag when using photoelectric components for deviation correction, the machine needs to be stopped for inspection and correction, which will affect the production and processing efficiency of the packaging bag.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the utility model is not limited to these embodiments.

[0032] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not very relevant are omitted.

[0033] Combination Figure 1 As shown, the embodiment of the utility model provides a packaging bag slitting device, which includes a bearing base 1 and a feeding roller 2, a first conveying roller 31, a second conveying roller 32, a tensioning rod 4, an upper flattening roller 51, a lower flattening roller 52, a cutting tool rod 6, a first receiving roller 71 and a second receiving roller 72 arranged on the bearing base 1.

[0034] The feeding roller 2 is located on one side of the supporting base 1 and is used to roll up the packaging bags to be cut;

[0035] The first conveying roller 31 and the second conveying roller 32 are arranged side by side in a transverse direction, and the first conveying roller 31 conveys the packaging bag released by the feeding roller 2 to the second conveying roller 32;

[0036] The tension rod 4 is located between the first conveying roller 31 and the second conveying roller 32, and is used to abut against and tighten the packaging bag between the first conveying roller 31 and the second conveying roller 32. Both ends of the tension rod 4 can be slidably raised and lowered in the waist-shaped holes opened on the supporting base 1.

[0037] The upper flattening roller 51 and the lower flattening roller 52 are arranged adjacent to each other, and the upper flattening roller 51 and the lower flattening roller 52 flatten the packaging bag sent out by the second conveying roller 32 through the gap between them;

[0038] Combination Figure 1 and Figure 2As shown, the cutting tool rod 6 is connected with a plurality of cutting tools 61, and the cutting tools 61 are used to cut the flattened packaging bags and send them to the first receiving roller 71 and the second receiving roller 72 for winding. The front end of each cutting tool 61 is fixed with a sensor receiving end 62, as shown in FIG. Figure 4 As shown, a sensor transmitting end 63 is correspondingly arranged directly below the sensor receiving end 62 to detect the position of the cutting point. Both ends of the cutting tool rod 6 can be slidably raised and lowered in the waist-shaped holes opened on the supporting base 1.

[0039] The packaging bag slitting equipment provided by the embodiment of the utility model, firstly, is based on setting a tension rod 4 between the first conveying roller 31 and the second conveying roller 32 for conveying continuous packaging bags, so that the tension rod 4 can be pressed on the packaging bag surface between the first conveying roller 31 and the second conveying roller 32, the packaging bag is tightened, more closely fitting the first conveying roller 31 and the second conveying roller 32, and the tension rod 4 can be used to lift and slide along the waist-shaped hole opened on the bearing base 1, and the height of the tension rod 4 is adjusted, that is, the pressing depth of the tension rod 4 is adjusted to achieve a suitable tension. It can not only avoid the bag body and the material roller from loosening and causing wrinkles, but also ensure the smooth conveyance of the packaging bag. Furthermore, the sensor receiving end 62 is fixed at the front end of the cutting tool 61, that is, beside the cutting point where the cutting tool 61 acts on the packaging bag. The height position of the cutting point can be determined according to the sensor receiving end 62 and the sensor transmitting end 63 directly below it, thereby determining the degree to which the cutting tool rod 6 cuts into the packaging bag before the first receiving roller 71 or the second receiving roller 72. Similar to the tensioning rod 4 mentioned above, the cutting tool rod 6 is also pressed on the surface of the packaging bag, which can also play the role of tightening the packaging bag. Moreover, before the packaging bag is cut, the upper flattening roller 51 and the lower flattening roller 52 flatten the packaging bag sent out by the second conveying roller 32 through the gap between them, so that before the packaging bag is sent to the cutting tool rod 6, the packaging bag is further flattened, further reducing the possibility of wrinkles, maintaining the efficient production and processing of the packaging bag, and reducing the occurrence of shutdown inspection conditions.

[0040] Combination Figure 2 and Figure 3As shown, a tension rod tightening handle 41 is provided at one end of the tension rod 4, a plurality of rotatable tension rollers 42 are connected to the tension rod 4, and a tool rod tightening handle 64 is provided at one end of the cutting tool rod 6. By adjusting the position of the end point of the tension rod 4 in the waist-shaped hole of the corresponding bearing base 1 and determining the height of the tension rod 4, the position of the tension rod 4 can be fixed by twisting the tension rod tightening handle 41. Similarly, by adjusting the position of the end point of the cutting tool rod 6 in the waist-shaped hole of the corresponding bearing base 1, the position of the cutting tool rod 6 can be fixed by twisting the tool rod tightening handle 64. The plurality of tension rollers 42 can rotate around the tension rod 4 under the action of the packaging bag in contact with them, and the tension rod 4 does not affect the normal transmission of the packaging bag.

[0041] In order to adjust the lateral width of the packaging bag after slitting according to operational requirements, that is, to adjust the lateral position of the cutting point, the cutting tool 61 can be slidably connected to the cutting tool rod 6, and the cutting tool 61 can slide horizontally on the cutting tool rod 6 to adjust the cutting point. The lateral width of the packaging bag is between the two cutting points or between the cutting point and the edge of the packaging bag.

[0042] A positioning block 65 is provided next to each cutting tool 61. The positioning block 65 can limit the position of the cutting tool 61 on the cutting tool rod 6, further fix the cutting tool 61, and make the cutting tool 61 more stable when cutting the packaging bag.

[0043] Since the cutting tool 61 equipped with the sensor receiving end 62 can slide laterally, correspondingly, the multiple sensor transmitting ends 63 can be slidably connected to the slide rail 11 set on the supporting base 1 through the sliding seat 66, and the sensor transmitting end 63 moves laterally by sliding on the sliding seat 66.

[0044] Specifically, the extending direction of the slide rail is consistent with the extending direction of the cutting tool rod.

[0045] Furthermore, the packaging bag slitting device further includes a first limiting groove 81, which is arranged between the cutting tool rod 6 and the upper flattening roller 51, and the opening of the first limiting groove 81 is arranged horizontally. The opening of the limiting groove 81 can limit the bending of the packaging bag, thereby further reducing the probability of wrinkles.

[0046] Furthermore, the packaging bag slitting device further comprises a second limiting groove 82 , wherein the second limiting groove 82 is arranged between the second conveying roller 32 and the upper flattening roller 51 , and the opening of the second limiting groove 82 is arranged longitudinally.

[0047] In order to facilitate the control of various components on the packaging bag slitting equipment, the packaging bag slitting equipment also includes a control console 9. The packaging bag slitting equipment includes drive motors for the first conveying roller 31 and the second conveying roller 32. The control console 9 is connected to the drive motor signal. Similarly, the drive mechanisms of the loading roller 2, the tensioning rod 4, the cutting tool 61, the sliding seat 66, the first receiving roller 71 and the second receiving roller 72 can all be connected to the control console 9 for unified control.

[0048] Since waste scraps may be generated after the cutting tool 61 cuts the packaging bag, a detachable waste collection bucket 12 is installed directly below the cutting tool 61, that is, next to the corresponding sensor transmitting end 63. The waste scraps generated by the cutting tool 61 will fall into the waste collection bucket 12. When a certain amount of waste scraps are collected, the waste collection bucket 12 can be easily removed from the supporting base 1 to dump the waste scraps. Furthermore, a fan is provided next to the sensor transmitting end, facing the waste collection bucket 12, and after starting, the waste scraps can be concentrated and blown to the waste collection bucket 12.
