[0001] The utility model relates to the technical field of packaging bag processing, in particular to a cutting device for a single-sided double-hole packaging bag. Background Art

[0002] Since the single-sided double-hole packaging bag is different from the traditional packaging bag in structure, in order to facilitate the rolling and packaging thereof, it is necessary to make an incision at the position of the double holes on the single side of the single-sided double-hole packaging bag before rolling and packaging.

[0003] When using the more conventional cutting equipment in the prior art to cut the single-sided double-hole packaging bag, technical personnel in this field found that the side of the single-sided double-hole packaging bag away from the cutter is easily damaged by the cutting of the cutter, which increases the defective rate and also increases the production cost of the single-sided double-hole packaging bag.

[0004] Therefore, it is necessary to invent a cutting device for a single-sided double-hole packaging bag to solve the above problems. Utility Model Content

[0030] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "above," "on," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0031] like Figure 1-Figure 3 As shown, the cutting device of the single-sided double-hole packaging bag disclosed in the present invention may include: a single-sided double-hole packaging bag conveying mechanism 1, a cutting mechanism 2, an inserting mechanism 3, a traction mechanism 4 and other components.

[0032] like Figure 2 As shown, in the present disclosure, the single-sided double-hole packaging bag conveying mechanism 1 includes a side plate 11, an input roller 12, a pad 13, an output roller 14 and a mounting plate 15, wherein the side plate 11 is symmetrically provided with two, the input roller 12 is sequentially arranged between the two side plates 11 from top to bottom, the input roller 12 and the output roller 14 are both rotatably connected to the side plate 11, the pad 13 is fixedly connected to the side plate 11, and the mounting plate 15 is located on one side of the pad 13 and is fixedly connected to the side plate 11.

[0033] Thus, the single-sided double-hole packaging bags connected end to end are input from the top right side of the input roller 12, pass through the inner side of the pad 13 and then go around to the outer side of the output roller 14, and finally are output from the bottom of the mounting plate 15 after being guided by the output roller 14.

[0034] like Figure 2 As shown, in the present disclosure, the cutting mechanism 2 includes a hydraulic cylinder 21, a movable plate 22, a first guide rod 23, a cutter 24 and a heating resistor 25, wherein the hydraulic cylinder 21 is fixedly arranged on the outer side of the mounting plate 15 and its output shaft slides through the mounting plate 15 and extends to the inner side of the mounting plate 15 and is fixedly connected to the movable plate 22, the first guide rod 23 slides through the mounting plate 15 and is fixedly connected to the movable plate 22, two cutters 24 are provided, and the two cutters 24 are respectively fixedly arranged at the two ends of the inner side of the movable plate 22, and the heating resistor 25 is located on the outer sides of the two cutters 24 and is fixedly connected to the movable plate 22.

[0035] Thus, the hydraulic cylinder 21 drives its output shaft to extend, and then the movable plate 22 drives the two cutters 24 to move right. During this process, the heating resistor 25 heats the cutter 24. As the cutter 24 continues to move right, the insertion mechanism 3 is inserted into the inner side of the single-sided double-hole packaging bag to separate it. Then the cutter 24 cuts the adjacent side of the single-sided double-hole packaging bag. During this process, the insertion mechanism 3 blocks the cutter 24 to prevent the cutter 24 from contacting the other side of the single-sided double-hole packaging bag.

[0036] like Figure 3 As shown, in a preferred embodiment, the insertion mechanism 3 includes a cross beam 31, an insertion plate 32 and a guide plate 33, wherein the insertion plate 32 is fixedly arranged at the bottom of the cross beam 31, the guide plate 33 is fixedly arranged at the bottom end of the insertion plate 32, and the front side of the guide plate 33 is provided with an inclined surface.

[0037] Thus, when the cross beam 31 moves downward, the insertion plate 32 and the guide plate 33 are driven downward synchronously. As the guide plate 33 continues to move downward, the guide plate 33 is inserted from the top opening of the single-sided double-hole packaging bag to the inner side thereof. At this time, the single-sided double-hole packaging bag needs one side of the cut to be close to the cutter 24.

[0038] like Figure 3 As shown, in the present disclosure, the traction mechanism 4 includes a second guide rod 41, a connecting block 42, a guide square tube 43, a traction rope 44 and a reset spring 45, wherein the second guide rod 41 is fixedly arranged at the bottom of the cross beam 31, the connecting block 42 is slidably sleeved on the outside of the second guide rod 41 and fixedly connected to the inner wall of the side plate 11, the guide square tube 43 is fixedly arranged on the inside of the connecting block 42, the traction rope 44 is slidably arranged on the inside of the guide square tube 43, one end of the traction rope 44 is fixedly connected to the bottom of the cross beam 31 and the other end is fixedly connected to the movable plate 22, and the reset spring 45 is sleeved on the outside of the traction rope 44 and fixedly connected between the cross beam 31 and the guide square tube 43.

[0039] In this way, the traction rope 44 is pulled when the movable plate 22 moves inward, and the traction rope 44 drives the cross beam 31 to move downward when being pulled. During the downward movement of the cross beam 31, it is guided by the second guide rod 41 and the connecting block 42, and the reset spring 45 is compressed at the same time. When the movable plate 22 is reset subsequently, the compressed reset spring 45 drives the cross beam 31 to move upward and reset.

[0040] like Figure 2As shown, the present disclosure further includes an adjusting mechanism 5, which includes a base plate 51, an adjusting bolt 52 and a third guide rod 53, wherein two base plates 51 are provided, the adjusting bolt 52 passes through the base plate 51 and is rotatably connected to the base plate 51 through a bearing, the third guide rod 53 is fixedly connected between the two base plates 51, the side plate 11 is sleeved on the outside of the adjusting bolt 52 and the third guide rod 53, the side plate 11 is threadedly connected to the adjusting bolt 52, and the side plate 11 is slidably connected to the third guide rod 53.

[0041] Therefore, when the position of the single-sided double-hole packaging bag conveying mechanism 1 needs to be adjusted, the adjusting bolt 52 is rotated. When the adjusting bolt 52 is rotated, the side plate 11 guided by the third guide rod 53 is driven to move, thereby completing the adjustment of the position of the single-sided double-hole packaging bag conveying mechanism 1.
