Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette detection equipment, in particular to a disassembly tool for a latex sleeve of a resistance-to-draw unit of a comprehensive test bench. Background Art
[0002] For the quality inspection of cigarette products, the physical index of cigarettes is an important inspection item, which can reflect the processing and manufacturing capabilities of cigarettes and embodies the quality management level of cigarette factories. The draw resistance is the most important one among the physical indexes of cigarettes and belongs to the A-class quality defect item. At present, all cigarette factories use comprehensive test benches to measure the draw resistance of cigarettes. Since the national standard for draw resistance detection has clear requirements, the measurement principles of the draw resistance units of various brands and models of comprehensive test benches are the same, and the design of the draw resistance measurement module is also similar. The cigarette is wrapped with a latex tube for inhalation, and the pressure at both ends of the cigarette is measured to calculate the pressure difference. The latex tube must be stretched and attached to the sleeve to wrap the cigarette. Since the latex tube is a rubber product, it is a wearing part and needs to be replaced regularly. The sleeve must be removed during replacement. The design of the sleeve itself is only slightly larger than the circumference of the cigarette and is a smaller component. It is tightly fitted with the draw resistance probe through a rubber ring to ensure the airtightness of the entire measuring device. Difficulty in removing the sleeve is a problem often encountered during maintenance.
[0003] Although the casing can be removed with other tools, it is very easy to damage the casing during the removal process because the casing is generally made of copper, which has low hardness, is small and smooth. It is difficult to find the fulcrum during removal and it is impossible to exert force with hands. There is a risk of damaging the casing using pliers or other tools made of hard materials. Utility Model Content

Because the material of the sleeve is generally copper material, the hardness itself is not high, it is small and smooth, and it is difficult to find the fulcrum during disassembly, and it is impossible to exert force by hand. There is a risk of damaging the sleeve when using pliers such as tools made of hard materials. When the absorption resistance unit of the comprehensive test bench is maintained, the tool for disassembling the latex sleeve of the absorption resistance unit of the comprehensive test bench directly inserts the catheter into the sleeve, and then tightens the knob at the end to make the tool and the sleeve tightly combined as one, so that the maintenance person can easily remove the sleeve. On the one hand, the difficulty in disassembling the sleeve due to the lack of fulcrum is avoided, and the device is simple to operate and easy to use. On the other hand, the non-hard material of the tool is tightly combined with the sleeve, so that the sleeve itself will not be damaged, and damage to the sleeve during disassembly using other rigid tools is avoided, thereby affecting the use state of the equipment and causing instability in the measurement result. At the same time, the tool has low manufacturing cost, is safe and reliable, and is easy to use.

[0022] In view of the problems existing in the prior art, the utility model provides a tool for disassembling the latex sleeve of the absorption resistance unit of the comprehensive test bench. When the absorption resistance unit of the comprehensive test bench is maintained, the catheter is directly inserted into the sleeve, and then the knob at the end is tightened to make the tool and the sleeve tightly combined as one, so that the maintenance personnel can easily take out the sleeve. On the one hand, the difficulty in disassembling the sleeve due to the lack of a fulcrum is avoided, and the device is simple to operate and easy to use. On the other hand, the non-hard material of the tool is tightly combined with the sleeve, so that the sleeve itself will not be damaged, and damage to the sleeve during disassembly using other rigid tools is avoided, thereby affecting the use state of the equipment and causing instability in the measurement result. At the same time, the tool has low production cost, is safe and reliable, and is easy to use.
[0023] Working principle:
[0024] In the first step, when it is necessary to replace the suction resistance latex tube and remove the casing, first insert the guide rod into the casing cavity, and then manually rotate the rear end knob to move the guide rod backward. The guide rod convex block can gradually squeeze the expansion tightening piece. By squeezing the expansion tightening piece, the tooling is firmly combined with the casing as a whole, so that the equipment maintenance personnel have a more ample force position and can easily remove the casing. After the casing is removed from the test head, the knob is rotated in the opposite direction to move the guide rod forward. The guide rod convex block gradually separates from the tensioning piece, and the tensioning piece also gradually separates from the casing. The tooling is removed, and the entire casing removal is also successfully completed, so that the device can effectively avoid the difficulty of removing the casing due to the lack of a force point, and the device is simple to operate;
[0025] In the second step, by using a tensioner made of non-hard materials, the casing will not be damaged during the disassembly process.
[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
