Description

Technical Field

[0001] The utility model relates to a tooling structure for loading and unloading screws, belonging to the field of coiling and packaging machinery. Background Art

[0002] The SE soldering iron device is an important part of the cigarette making system. Its function is to dry the glue on the joint of the cigarette rod after rolling and forming, so that it can be quickly formed, keep the diameter of the cigarette rod stable, and avoid problems such as loose adhesion and quality defects. Therefore, the position of the soldering iron relative to the cigarette rod should be accurately adjusted to achieve the purpose of meeting the process standards.

[0003] At present, Ningbo Cigarette Factory has a total of 23 sets of medium and high-speed cigarette equipment, which are the main models of our factory and account for a large proportion of our production capacity. In recent years, due to the deviation of the working position of the SE soldering iron device, the maintenance frequency is high, and there are many product quality problems such as low circumference compliance rate of cigarettes. Due to the small operating space for adjusting the horizontal position screw of the soldering iron, the installation and removal of the screw for adjusting the horizontal position of the soldering iron with ordinary wrench tools takes a long time, which affects the time loss of the entire soldering iron adjustment, which is not conducive to the improvement of equipment operation efficiency and product quality.

[0004] By counting the adjustment and calibration of soldering irons by multiple maintenance personnel from June to December 2023, it was found that each maintenance personnel took a long time to make adjustments, with an average of 39.8 minutes required each time until the equipment ran stably. During the whole process, problems such as smoke explosion, soldering iron runaway, soldering iron marks, and rework were common, which seriously affected the equipment operating efficiency and product quality.

Example

[0029] This embodiment introduces a screw loading and unloading tooling structure, including a rotating rod 1, a rotating rod threaded cover 4, a sleeve barrel 2 and a sleeve barrel threaded cover 3; the lower end of the sleeve barrel 2 and the upper end of the sleeve barrel threaded cover 3 are screwed together, the rotating rod 1 passes through the screwed sleeve barrel 2 and the sleeve barrel threaded cover 3, and the lower end of the rotating rod 1 is screwed together with the rotating rod threaded cover 4.

[0030] This embodiment overcomes the technical problem that during the adjustment process, because the screws for adjusting the horizontal position of the soldering iron are in a small operating space, it takes a long time to load and unload the screws with ordinary wrench tools, which affects the time loss of the entire soldering iron adjustment and is not conducive to improving the equipment operation efficiency and product quality. The SE soldering iron device can be quickly adjusted, the adjustment time is reduced, and the maintenance efficiency and equipment effective operation rate are improved. The tooling reduces the average single adjustment time by 5 minutes. When used in ZJ17 equipment, the time cost and labor cost of a single replacement are reduced. Example

[0031] Based on Example 1, this example introduces a specific implementation method of the screw assembly and disassembly tooling structure, and further explains each unit structure:

[0032] The screw loading and unloading tooling structure comprises a rotating rod 1, a rotating rod threaded cover 4, a sleeve barrel 2 and a sleeve barrel threaded cover 3;

[0033] The upper end of the rotating rod 1 is provided with a handle 1.1, and the handle 1.1 includes two sections of cylinders, the axes of which are located on the same horizontal line and are respectively arranged on both sides of the rotating rod 1. The operator uses the handle 1.1 to realize the rotation operation of the rotating rod thread cover 4. The surface of the cylinder provided on the handle 1.1 is provided with an anti-slip thread structure, which prevents the operator from slipping when holding the handle 1.1 to rotate the rotating rod thread cover 4, thereby enhancing the friction of the operator on the handle 1.1.

[0034] The outer surface of the lower end of the rotating rod 1 is provided with a threaded structure, and the upper end of the inner wall of the rotating rod threaded cover 4 is provided with a threaded structure. The lower end of the rotating rod 1 is screwed with the inner wall of the rotating rod threaded cover 4 through the threaded structure. The rotating rod threaded cover 4 completely coincides with the central axis of the rotating rod 1. The rotating rod threaded cover 4 is driven to rotate by rotating the handle 1.1 to complete the loading and unloading of the nut. The lower end of the inner wall of the rotating rod threaded cover 4 is provided with a nut bayonet that matches the nut to be tightened; the rotating rod threaded cover 4 can be replaced according to actual needs to adapt to different application scenarios. The nut bayonet can be a four-corner or a hexagonal one, that is, the four-corner rotating rod threaded cover 4.1 and the hexagonal rotating rod threaded cover 4.2 in the figure.

[0035] A fixed handle is provided on one side of the upper end of the sleeve body 2, which is convenient for the operator to fix the loading and unloading area and lock the sleeve body 2. An anti-slip sleeve 2.1 is provided on the fixed handle to increase the friction of the operator on the fixed handle. An opening is provided on one side of the sleeve body threaded cover 3 to facilitate the sleeve body 2 to extend into the loading and unloading area.

[0036] The upper end of the inner wall of the sleeve barrel threaded cover 3 is provided with a threaded structure, and the inner wall of the lower end of the sleeve barrel 2 is provided with a threaded structure. The inner wall of the lower end of the sleeve barrel 2 and the upper end of the sleeve barrel threaded cover 3 are screwed together through the threaded structure, and the central axis of the sleeve barrel 2 and the sleeve barrel threaded cover 3 completely coincide with each other; through the cooperation of the sleeve barrel 2 and the sleeve barrel threaded cover 3, the position of the loading and unloading area is further fixed, and the accuracy of the rotating rod threaded cover 4 for loading and unloading nuts is improved. The lower end of the inner wall of the sleeve barrel threaded cover 3 is provided with a nut bayonet that matches the nut to be tightened; the sleeve barrel threaded cover 3 is a replaceable structure to adapt to the application of different scenarios, so that this tooling structure has a certain degree of operational flexibility, a wider range of application, and high interchangeability.

[0037] After the rotating rod 1 passes through the threaded sleeve barrel 2 and the sleeve barrel threaded cover 3, the lower end of the rotating rod 1 is threadedly connected to the rotating rod threaded cover 4.

[0038] When the utility model is working, the sleeve body threaded cover 3 is fixed with the nut of the fixed tooling, and the rotating rod threaded cover 4 is fixed with the nut to be loaded and unloaded. The maintenance personnel hold the fixed handle with one hand and rotate the handle 1.1 with the other hand, so that the nut to be loaded and unloaded can be loaded and unloaded smoothly. If screws of other specifications and shapes are encountered, the rotating rod threaded cover 4 can be replaced, and other rotating rod threaded covers 4 that meet the conditions can be developed for loading and unloading.

[0039] When in use, the tooling occupies a small space and can easily load and remove screws that do not have sufficient space, thereby improving the efficiency of maintenance personnel in adjusting the position of the SE soldering iron, reducing the adjustment time, and improving maintenance efficiency and effective operation rate of equipment.
