[0002] A fresh-keeping bag is a plastic bag used to store food and extend its shelf life. These bags are usually made of special materials and have airtightness and antibacterial properties to prevent food from being contaminated by air, moisture and bacteria. After the fresh-keeping bags are produced, in order to facilitate users to separate and use them, they are generally die-cut at easy-to-tear points at specific intervals. When performing the die-cutting process, the existing device relies on hydraulic equipment to drive the tool to die-cut and press the surface of the fresh-keeping bag, so that multiple holes can be formed on the fresh-keeping bag, which is convenient for users to tear. However, it is worth noting that for fresh-keeping bags of different specifications, the operator needs to replace the corresponding tool for cutting. The replacement process will take a lot of time, thereby reducing the overall die-cutting efficiency.

[0003] Therefore, a fresh-keeping bag processing easy-tear point die-cutting device is now developed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] A fresh-keeping bag processing easy-tear point die-cutting device, such as Figure 1 and Figure 3 As shown, it includes a mounting platform 1, and the upper sides of the front and rear parts of the mounting platform 1 are connected to the first hydraulic cylinder 2, the telescopic ends of the first hydraulic cylinder 2 are all arranged downward, and the telescopic ends of the first hydraulic cylinder 2 are connected to the mounting platform 1, a first mounting plate 3 is connected between the first hydraulic cylinders 2, and four second hydraulic cylinders 4 are connected to the first mounting plate 3, and the telescopic ends of the second hydraulic cylinders 4 are all arranged downward, and a protective cover 5 is connected between the telescopic ends of two adjacent second hydraulic cylinders 4, and a first blade 6 for easy-tear point die-cutting of fresh-keeping bags is connected in the protective cover 5, a second blade 7 is slidably connected in the first blade 6, and a locking member 8 is connected between the first blade 6 and the second blade 7, a first conveying roller 9 is rotatably arranged on the upper part of the mounting platform 1, and a feeding mechanism 10 for automatically conveying and transporting fresh-keeping bags is arranged on the right part of the mounting platform 1.

[0023] like Figure 1 and Figure 4 As shown, the feeding mechanism 10 includes a second mounting plate 101, the second mounting plate 101 is connected to the right side of the mounting platform 1, a screw rod 102 is connected to the second mounting plate 101, the front and rear ends of the screw rod 102 are threaded, the front and rear ends of the screw rod 102 are threadedly connected to knobs 103, the knobs 103 are provided with power-assisting grooves, two first lower pressure plates 104 for pressing the fresh-keeping bags are rotatably provided on the right side of the mounting platform 1, and a feeding assembly 105 for driving the feeding movement of the fresh-keeping bags is provided on the right side of the mounting platform 1.

[0024] It should be noted that when processing the fresh-keeping bag, it is necessary to perform easy-tear die-cutting on the fresh-keeping belt. The present device can be used to guide and convey the fresh-keeping bag, and then perform die-cutting. First, the knob 103 is rotated and removed, and then the fresh-keeping belt cover is placed on the front and rear ends of the screw rod 102. Then the knob 103 is rotated and reset to limit the fresh-keeping bag. Then the first lower pressure plate 104 is rotated to press and limit the fresh-keeping bag. Then the fresh-keeping bag is pulled out and passes through the feeding assembly 105. Then the fresh-keeping bag is guided to the first conveying roller 9. The first conveying roller 9 is driven to rotate by the driving device, so that the fresh-keeping bag can be automatically fed. During the feeding process, the first conveying roller 9 is started. A hydraulic cylinder 2 and a second hydraulic cylinder 4 are used to drive the protective cover 5 to move downward. During the downward movement of the protective cover 5, the first blade 6 and the second blade 7 are driven to move downward, thereby completing the die-cutting process of the fresh-keeping bag. When special instructions are required, before the device performs die-cutting on the fresh-keeping bag, the locking piece 8 can be opened to unlock the second blade 7 according to the specifications of the fresh-keeping bag, and then the second blade 7 can be slid to adjust the spacing between the cutting teeth of the first blade 6 and the second blade 7. After the adjustment is completed, the second blade 7 is locked and fixed again by the locking piece 8, so that the first blade 6 and the second blade 7 can remain stable, thereby achieving the effect of quickly adjusting the spacing between the easy-to-tear points.

[0025] Example 2

[0026] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a winding mechanism 11, and the winding mechanism 11 includes a mounting seat 111. The mounting seat 111 is placed on the left part of the mounting platform 1, and a double-axis motor 112 is installed on the upper left side of the mounting seat 111. The output shaft of the double-axis motor 112 is arranged in a front-to-rear direction, and a locking assembly 113 is threadedly connected to the output shaft of the double-axis motor 112. The connecting rod on the right side of the locking assembly 113 is slidably connected to the mounting seat 111, and the upper left part of the mounting seat 111 is rotatably connected to two second lower pressure plates 114 for pressing the fresh-keeping bags in the rolled state, and the upper part of the mounting seat 111 is rotatably connected to the second conveying roller 115, and the right part of the mounting seat 111 is connected to a baffle plate 116 for guiding the movement of the fresh-keeping bags after die-cutting.

[0027] It should be noted that after the die-cutting of the fresh-keeping bags is completed, the baffle plate 116 is used to guide the die-cut fresh-keeping bags to prevent the bags from stacking. At the same time, the fresh-keeping bags are guided to the position of the second conveying roller 115, and then the second conveying roller 115 is driven to rotate by the driving device, so that the die-cut fresh-keeping bags can move automatically. Then, the fresh-keeping bags are wound around the output shaft of the dual-axis motor 112, and the locking assembly 113 is used to limit the front and rear directions of the fresh-keeping bags in the rolled state. At the same time, the second lower pressure plate 114 is used to press the fresh-keeping bags in the rolled state to improve the rolling stability.
