[0031] Example 1;

[0032] The No. 4 wheel exit lifter belt in tobacco manufacturing is a commonly used conveyor device in industrial production. The accuracy of lifter belt installation is crucial in cigarette production. The No. 4 wheel exit lifter belt is mainly used to convey cigarette packs to the fifth wheel. Its accuracy is paramount, ensuring the stability and precision of cigarette pack transport. Incorrect installation can lead to damage to the mold box or cigarette packs, affecting the quality of accessories and the cigarette packs. During operation, misalignment can occur due to various reasons, requiring zeroing and calibration. Current technology often uses phase fixtures for calibration, but this requires removing the diaphragm box 13, a cumbersome process with significant downtime, severely impacting work efficiency.

[0033] The No. 4 pulley outlet lifting belt has a unique characteristic: when calibrated, the position of the diaphragm box 13 within the lifting belt remains unchanged relative to the position of the base 11 of the conveyor belt 12 in a zero-degree Celsius environment. Utilizing this characteristic, this invention provides a tooling device for the No. 4 pulley outlet lifting belt, capable of quickly assisting in zeroing and calibration. Figures 1-4As shown, a lifting belt tooling device for the outlet of a No. 4 wheel includes a lifting device 1, which includes a base 11, a conveyor belt 12, and diaphragm boxes 13. The conveyor belt 12 is mounted on the base 11. There are multiple diaphragm boxes 13, which are equidistantly fixed on the conveyor belt 12. The device also includes a positioning tooling 2 and a positioning pin 3. The positioning tooling 2 includes a clamping part 21, a positioning part 22, and a tooling positioning hole 24. The clamping part 21 is perpendicularly fixed to the positioning part 22. The tooling positioning hole 24 is located on the positioning part 22. The clamping part 21 can be assembled between two diaphragm boxes 13. The positioning part 22 fits against the base 11. The base 11 is provided with a base positioning hole 14. The positioning pin 3 is inserted into the base positioning hole 14 and the tooling positioning hole 24. In a zero-degree Celsius environment, the positioning fixture 2 is clamped between the lifting belt membrane box 13, and the relative position of the lifting belt and the base 11 is adjusted. The zeroing calibration of the No. 4 wheel outlet lifting belt is completed when the positioning pin 3 can be inserted into the base positioning hole 14 and the fixture positioning hole 24 at the same time.

[0034] The positioning fixture 2 has two fixture positioning holes 24, two base positioning holes 14, and two positioning pins 3. The two positioning pins 3 are inserted one-to-one into the two base positioning holes 14 and the fixture positioning holes 24. By setting two fixture positioning holes 24 and two base positioning holes 14, in conjunction with the two positioning pins 3, precise positioning is achieved. This multi-point positioning design effectively improves the stability and accuracy of the calibration between the lifting belt and the base 11, avoiding deviations or misalignments that may be caused by single-point positioning, and ensuring the reliable operation of the lifting belt after calibration. The chamfered design at the top of the positioning pin 3 makes it easier to insert the pin into the positioning hole, reducing possible jamming during insertion, significantly improving the efficiency of the calibration operation, and reducing the skill requirements for the operator, thus simplifying the workflow. The groove 23 on the clamping part 21 of the positioning fixture 2 reduces the overall weight of the fixture, lowering the burden of manual operation and making the fixture lighter and more flexible during installation, disassembly, or transportation, thereby further improving the convenience of the calibration process. This design reduces tooling weight while maintaining structural strength and stability, avoiding installation difficulties or user fatigue caused by excessive weight. The overall design significantly shortens zeroing calibration time while ensuring accuracy, reducing production efficiency losses due to equipment downtime, and avoiding the cumbersome steps of frequently disassembling and reassembling the diaphragm box 13 in traditional calibration methods. This embodiment achieves rapid, accurate, and simplified zeroing calibration of the lifting belt, which is of great significance for the stable conveying of the lifting belt and the efficient operation of equipment in tobacco production.

[0035] For ease of operation, the positioning pin 3 is a fixed positioning pin 31, which is fixedly connected to the positioning hole 24 of the tooling. The design of the positioning pin 3 as a fixed positioning pin 31 integrates the positioning pin 3 with the positioning hole 24, effectively preventing positioning errors caused by loosening or falling off during use, and improving the reliability and consistency of the calibration operation. The structure of the fixed positioning pin 31 ensures that it remains in the correct working position during calibration, eliminating the need for frequent adjustments or reinstallation, thus further simplifying the operation and reducing equipment downtime. Simultaneously, the fixed positioning pin 31 avoids the wear and loosening problems that may occur with traditional detachable positioning pins 3 during repeated insertion and removal, extending the service life of the tooling and reducing the frequency of equipment maintenance.

[0036] Example 2;

[0037] The difference from Embodiment 1 is that, in this embodiment, as... Figure 5 and Figure 6 As shown, the positioning pin 3 is designed as a base elastic positioning pin 32, which includes a first spring 321 and a first pin 322. One end of the first spring 321 is fixed to the bottom of the base positioning hole 14, and the other end is fixed to the first pin 322. In the relaxed state, the first pin 322 extends beyond the base positioning hole 14, and during the calibration operation, the first pin 322 is pressed into the base positioning hole 14 by external force. When the conveyor belt 12 of the lifting belt is adjusted to the zero position, the rebound force of the first spring 321 causes the first pin 322 to automatically spring into the tooling positioning hole 24, forming a precise alignment and sending a clear feedback signal to indicate that the calibration operation has been completed. The application of this elastic positioning mechanism significantly simplifies the operation process, avoids the complex steps of repeatedly checking the zero position manually, and improves the efficiency and accuracy of calibration. The first pin 322 can automatically adapt to small positional deviations between the positioning holes during the calibration process, thereby reducing component wear caused by forced insertion or positioning failure caused by misalignment. The dynamic rebound characteristic of the spring structure ensures the stability of the positioning pin 3 upon completion of calibration, while effectively preventing loosening or dislocation caused by external disturbances. The design of the elastic positioning pin 3 also provides clear physical feedback signals during the belt calibration process, enabling operators to quickly determine the calibration status and reducing the probability of human error. This structural optimization balances ease of operation and positioning accuracy, not only shortening equipment downtime but also improving the stability and consistency of zeroing calibration, providing crucial support for the long-term operation of the belt and further enhancing the overall efficiency and automation of the tobacco production line.

[0038] Example 3;

[0039] The difference from Embodiment 1 and Embodiment 2 is that, in this embodiment, as Figures 7-9As shown, the locating pin 3 is designed as a tooling elastic locating pin 33 and is installed in the tooling locating hole 24. The tooling elastic locating pin 33 consists of a threaded outer shell 331, a nut 332, a second pin 333, a second spring 335, and a pull ring 334. The threaded outer shell 331 includes a limiting shell 3311 and a threaded shell 3312. The limiting shell 3311 is inserted into the tooling locating hole 24, and the threaded shell 3312 passes through the locating part 22 and is fixed by the nut 332, ensuring that the tooling elastic locating pin 33 is securely installed on the tooling locating hole 24. At the same time, in order to avoid the nut 332 affecting the normal placement of the locating tool 2, the locating part 22 at the locating hole is designed to be relatively thin, thereby ensuring the compactness and stability of the assembly. The second pin 333 has a design that is thicker at the top and thinner at the bottom. Its thinner lower portion passes through the limiting shell 3311 and is fitted with the second spring 335. One end of the spring is fixed to the second pin 333, and the other end is fixed to the bottom of the limiting shell 3311, allowing the second pin 333 to move axially within the threaded housing 331. When the calibration operation begins, the positioning fixture 2 is clamped between the lifting belt diaphragm box 13, and the positioning part 22 is fixedly contacted with the base 11. The operator controls the position of the second pin 333 through the pull ring 334. Under the external force applied by the base 11, the second pin 333 is compressed into the limiting shell 3311, and the spring is simultaneously compressed. As the lifting belt is adjusted to the zero position, the spring's rebound force pushes the second pin 333 downwards. When the end of the second pin 333 is precisely inserted into the positioning hole 14 of the base, the zeroing calibration operation is complete. This physical feedback effectively reminds the operator of the calibration status. This design ensures stable alignment of the second pin 333 with the base positioning hole 14 after calibration, while avoiding insertion difficulties and equipment wear caused by positional errors in traditional rigid pin calibration. The top-thicker, bottom-thin design of the second pin 333 not only optimizes the spring's sleeve position but also reduces frictional resistance, further improving the smoothness and accuracy of the calibration operation. The tight fit between the threaded housing 3312 and the nut 332 keeps the tooling elastic positioning pin 33 stable during positioning, avoiding loosening or displacement caused by external vibration or impact. In addition, the design of the pull ring 334 simplifies the operation of the second pin 333, allowing operators to quickly control the axial movement of the pin, improving calibration efficiency while reducing operational difficulty. Through this optimized design, the tooling elastic positioning pin 33 can adapt to possible slight deviations between the base positioning hole 14 and the tooling positioning hole 24, while providing clear physical feedback signals after calibration, significantly improving the reliability and efficiency of the calibration process, reducing equipment downtime, and playing an important role in the stable operation and automated calibration of the tobacco production line.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
