Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to an easy-tear strip packaging structure. Background Technology

[0002] The strip package is not precisely positioned in the left and right directions in the easy-tear mechanism, causing the cut easy-tear line to deviate left and right. This is because the original guiding mechanism is limited to the bulging part in the middle of the strip package. However, due to the filling material, the width of the bulging part is not fixed and is smaller than the width of the sealing part, causing the strip package to swing left and right in it. Therefore, it will lead to misalignment after pre-compression, resulting in the easy-tear knife cutting off the correct direction.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0025] The pre-compression structure 600 includes: a guide positioning pin 610, a guide shaft mounting plate 620, a guide shaft 630, a fixing screw 640, a spring 650, an oil-free bushing 660, and a fixing block 670. The guide positioning pin 610 is a conical structure. One end of the guide positioning pin 610 is fixed to the guide shaft mounting plate 620, and the other end of the guide positioning pin 610 is connected to the guide structure 800 during use. One end of the guide shaft 630 is connected to the fixing block 670 through the fixing screw 640, and the other end of the guide shaft 630 is connected to the oil-free bushing 660. The spring 650 is connected to the guide shaft 630. The oil-free bushing 660 connects the guide shaft mounting plate 620 and the fixing block 670. The fixing block 670 is connected to the cutter structure 500.

[0026] The cutter structure 500 includes: a cutter fixing seat 510, a cutter 520 and a transmission seat 530. The two ends of the cutter fixing seat 510 are connected to the linear bearing 300 through the guide shaft 700. The cutter 520 and the transmission seat 530 are mounted on the cutter fixing seat 510. The transmission seat 530 is connected to the fixing block 670.

[0027] The guide structure 800 includes: a guide support plate 810, a guide plate 820 and a guide hole 830. The guide support plate 810 is connected to the fixed base 200 on both sides. The guide support plate 810 is provided with a guide plate 820 at its upper end. The guide support plate 810 is provided with a guide hole 830. When in use, the guide hole 830 is connected to the guide positioning pin 610.

[0028] The blowing pipe structure 900 includes: a blowing pipe fixing block 910, an adjusting stud 920, and a cooling blowing pipe 930. One end of the adjusting stud 920 is connected to the fixing base 200, and the other end of the adjusting stud 920 is connected to the blowing pipe fixing block 910. The blowing pipe fixing block 910 is connected to the cooling blowing pipe 930.

[0029] The method of using this utility model is as follows: when the strip package 1 passes through this mechanism from top to bottom, it is guided by the guide structure 800 to make a basic fixation, and then the pre-compression structure 600 fixes the strip package 1 more firmly. The pre-compression structure 600 and the cutting structure 500 are synchronized, and the easy-tear processing of the strip package 1 is completed when it is fixed instantly.

[0030] The innovation of this utility model lies in the addition of a pre-compression structure 600. The core of the pre-compression structure 600 is the guide positioning pin 610. When the guide positioning pin 610 passes through the strip package 1, the width of the cutter is maximized, allowing the integrated strip package to smoothly pass through the next station. When it reaches the easy-tear cutting point, the linear bearing 300 drives the cutter 520, and then the guide shaft mounting plate 620 is pressed together. The spring 650 buffers and presses the strip package 1. At the same time, under the guidance of the guide positioning pin 610, the strip package 1 is limited at the sealing width, ensuring that the strip package 1 is centered and does not deviate. Finally, the cutter 520 cuts in, forming a dotted easy-tear opening. Finally, the cylinder resets, the guide shaft mounting plate 620 disengages, and the strip package 1 continues to pass through the next station, and so on.

[0031] The reason why the guide positioning pin can achieve the above operation is that it has a conical structure design with a small head and a large bottom, which can achieve the function of avoiding gaps and allowing the strip to pass through smoothly. When the guide shaft mounting plate 620 is pre-pressed, the root of the guide positioning pin 610 is consistent with the width of the strip 1, and the strip 1 is automatically positioned to the center point, avoiding the strip from being misaligned after pre-pressing, which would cause the cutter 520 to cut off-center.

[0032] Compared with traditional technology, this utility model adds a pre-compression structure to fix the easy-tear opening of the strip package, avoiding the strip package from shifting after pre-compression, which would cause the easy-tear knife to cut off-center.

[0033] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
