Abstract
Description
Technical Field
[0001] The utility model relates to a cigarette package untying knife, belonging to the technical field of cigarette package verification. Background Art
[0002] Cigarette package review is an important task in tobacco leaf production in the tobacco industry. The tobacco leaf production process includes classification, grading, weighing, warehousing, packaging, review, etc. Among them, the review is mainly to check the weight and grade of the cigarette package to see if it exceeds the specified deviation. At present, the review work mainly involves taking cigarette package samples in the warehouse, then weighing and grading them and recording them in a notebook, and then entering them into the system for comparison and review. In the review work, since the current cigarette packages are tied with dead knot ropes, scissors or utility knives are usually used to untie the ropes when unpacking. Since the cigarette package ropes are usually hemp ropes, scissors need to be operated with force, and it is inconvenient to cut with utility knives. For this reason, staff often use, for example, watermelon knives to operate, and watermelon knives have safety hazards during operation, and it is easy to damage the cigarette package if the force is not used properly. It is necessary to study and improve this. Utility Model Content

[0017] ,Specific implementation method
[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0019] See also Figures 1 to 3The present embodiment is a cigarette pack untying knife, comprising a handle 1, a knife shell 2 and a blade 3. The knife shell 2 is fixed at the end of the handle 1, the knife shell 2 is in the shape of an elongated strip, and one long side of the knife shell 2 is an open end. A slide groove 23 is arranged along the width direction of the knife shell 2 in the knife shell 2, and a strip-shaped opening 24 connected to the slide groove 23 is arranged on the knife shell 2 along the width direction of the knife shell 2. The blade 3 can be movably installed in the slide groove 23, and a slider 5 is arranged in the slide groove 23. The slider 5 is detachably fixedly connected to the blade 3, and the slider 5 can synchronously slide back and forth in the slide groove 23 along its length direction. A push block 6 extending out of the strip opening 24 is fixed on the slider 5, so that the slider 5 can be driven to move by the push block 6, and then the blade 3 can be driven to move back and forth in the slide groove 23 so as to extend out of the open end or shrink in the open end. A hook groove 4 is provided on the blade of the blade 3, and the direction of the hook groove 4 forms an acute angle with the section of the blade 3 close to the handle 1. The inner wall surface of the hook groove 4 is the blade, so that the end of the hook groove 4 facing the handle 1 can be used to cut the cigarette pack rope.
[0020] Furthermore, the blade housing 2 includes a blade body housing 21 and a blade end housing 22. One end of the blade body housing 21 is connected to the handle 1, and the other end is connected to the blade end housing 22. The open end is provided on the blade body housing 21, and the outer end of the blade end housing 22 and the end corresponding to the open end are closed. The blade end housing 22 can limit the movement range of the blade 3 to prevent the blade 3 from slipping out of the blade body housing 21.
[0021] Furthermore, the slide groove 23, the slider 5 and the push block 6 are two groups, which are respectively arranged on both sides of the long side of the knife housing 2, and the movement operation of the blade 3 can be synchronously realized through the two groups of slide grooves 23, sliders 5 and push blocks 6. It should be noted that the structure of the slider 5 and the push block 6 is similar to the sliding structure principle of the utility knife.
[0022] Furthermore, the hook groove 4 includes an open groove 41 and a sharp hook portion 42. The open groove 41 is formed on the blade 3, and the sharp hook portion 42 is arranged on the end of the open groove 41 away from the handle 1, and the sharp hook portion 42 extends to a predetermined distance outside the blade 3. This structure makes operation more convenient.
[0023] Furthermore, a fixing hole 7 is provided on the blade 3, and a fixing column 8 matching with the fixing hole 7 is provided on the slider 5. The fixing column 8 is installed in the fixing hole 7, which has a simple structure and is easy to install and disassemble.
