Description

Technical Field

[0001] The present invention relates to the technical field of trumpet mouth adjustment, and in particular to a method for quickly correcting a double-track double-row rotating trumpet mouth. Background Art

[0002] The ZJ119 cigarette maker is the latest generation of domestically produced cigarette makers. This equipment features dual-gun rolling and forming, employing either a dual-track, dual-row rotating horn nozzle or a crank-driven dual-pass horn nozzle. A dual-head cutter disc slits double-length tobacco rods to complete the production process. The dual-track, dual-row rotating horn nozzles rotate clockwise in sync with the horizontal movement of the blades, while eight rotating horn nozzle brackets rotate counterclockwise to maintain a constant horizontal position, parallel to the tobacco rod path, and aligned with the horizontal speed of the corresponding cutters on the cutter disc. During rod slicing, the horn nozzle's U-shaped groove arc is coaxial with the tobacco rod's V-shaped path, with the cutters parallel to the horn nozzle's working surface and the cutting path perpendicular to the rod axis, effectively slicing the tobacco rod into double-length rods. This constant parallelism between the horn nozzle and cutter provides smoother operation, with lower vibration and noise, and no impact stress on components, compared to a crank-driven dual-pass horn nozzle with an arc-shaped swing.

[0003] In the actual production process, the double-track double-row rotating bell nozzle has the advantages of low noise, stable load, and high synchronization. At the same time, there are higher requirements for maintenance and adjustment accuracy. During the adjustment process, it is necessary to ensure that the horizontal positions of the four groups of bell nozzles are consistent, and the corresponding cutting blades of the cutter disc are in contact on the right side, with a gap of 0.5mm on the left side. The adjustment process needs to be repeated 16 times to ensure that the calibration is accurate once. The actual position of the cutter in the gap of the bell nozzle will change slightly with the operating speed of the equipment. Therefore, after the static adjustment, the equipment needs to be operated to observe the relative position of the high-speed blade cutting and the bell nozzle for further adjustment. The adjustment process uses the method of observing the contact scratches between the cutter and the bell nozzle to determine the running fit, and the relative position of the bell nozzle and the cutter is adjusted by visual inspection and feel.

[0004] The patented rolling and splicing equipment has 8 pairs of double-track, double-row rotating trumpet nozzles, which need to be calibrated one by one. Each pair of trumpet nozzles must be coaxial with the tobacco rod channel, synchronized with the horizontal speed of the corresponding cutter on the knife disc, and the distance between the inlet and outlet trumpet nozzles and the two sides of the cutter must meet the technical requirements. During the adjustment process, the cutting surface of the front and rear double-row inlet trumpet nozzles of the same group at the same cutting position must be parallel to the right side of the corresponding cutter, and the working surface of the outlet trumpet nozzle must be parallel to the left side of the cutting blade with a gap of 0.05mm. Adjustment can only be made by visually inspecting the contact scratches between the cutter and the trumpet nozzle during the machine running-in. The relative position of the inlet side of each group of trumpet nozzles and the cutter is determined one by one. The scratches on the same side of the front and rear double rows are difficult to determine the source, and repeated inspection and adjustment are required. The adjustment takes a long time and cannot guarantee the accuracy, resulting in problems such as bevels and burrs on the blade that are difficult to fundamentally solve.

[0005] Currently, there is no standardized method or tooling for adjusting the gap, and it takes a long time, usually five or six hours, which needs to be improved. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the technical problems to be solved are: providing a standardized adjustment method and process, standardizing the order and method of adjusting 16 horn nozzles, eliminating the waste of time, personnel and materials in the repeated adjustment process, and reducing abnormal consumption and quality risks caused by product quality problems; therefore, special adjustment tooling is designed to accurately position according to a specific order and adjustment method, improve the installation and positioning efficiency and accuracy of 4 groups of 8 pairs of 16 horn nozzles, and eliminate the blade quality problems caused by the unevenness of the horn nozzle bracket and inconsistent gap position.

[0007] The technical solution of this application is:

[0008] A method for quickly correcting a double-track double-row rotating horn nozzle is provided for adjusting and correcting eight pairs of horn nozzles of a double-track double-row rotating horn nozzle; the method comprises the following steps:

[0009] S1, making a special tool; the special tool is provided with a surface a and a surface b perpendicular to each other; the surface a is in contact with the top surface of the trumpet mouth rotating arm;

[0010] S2, first adjust the relative position of a bell mouth and the cutting knife in the first group of the first row;

[0011] S3, using a dedicated tool, adjusting the second horn mouth in the first group of the first row based on the horn mouth in step S2;

[0012] S4, repeat steps S2 and S3, and adjust the remaining three rows of horn mouths in sequence.

[0013] Further, S2 includes the following steps:

[0014] S21, remove the bolt that secures the first set of two bell mouths and fix the special tooling on the rotating arm of the bell mouth;

[0015] S22, observe the level on the special tooling to ensure that the rotating arms of the two horn nozzles are on the same horizontal plane;

[0016] S23, loosen another bolt fixing the first set of horn nozzles so that the gap between the horn nozzles and the b-surface of the special tooling is 0.5 mm; then fix the bolt to the horn nozzle rotating arm;

[0017] S24, paint the blade with color, rotate the cutting blade, and observe the fit between the two sides of the blade and the bell mouth; if the right side of the blade fits the corresponding cutting blade of the cutter disc, and there is a 0.5mm gap on the left side, it is qualified, otherwise readjust;

[0018] S25. After the bell mouth and the blade are properly adjusted, remove the special tooling, then install the second bolt on the bell mouth and the adjustment is complete.

[0019] Furthermore, in step S22, the levels of the two rotating arms of the horn mouth are fixed so that a 0.01 mm thick feeler gauge cannot be inserted into the gap between the special tooling and the rotating arms of the horn mouth.

[0020] Furthermore, in step S23, when the blade is rotated, if the blade cannot pass through the bell mouth, the blade is reversed and the position of the bell mouth is readjusted until the blade cannot pass through forcibly.

[0021] A special tool for adjusting a trumpet mouth comprises an L-shaped adjustment seat; a finely machined surface a is provided on the top edge of the adjustment seat, and a finely machined surface b is provided on the side edge of the adjustment seat; the surface a is perpendicular to the surface b; and the surface a is in close contact with a rotating arm of the trumpet mouth.

[0022] The rotating arm is fixedly connected to the trumpet mouth by two bolts; a strip hole is provided on the top edge of the adjustment seat, and the diameter of the strip hole is larger than the diameter of the bolt.

[0023] Remove one bolt that fixes the horn mouth, and use the first bolt and washer to fix the A surface of the adjustment seat to the horn mouth rotating arm.

[0024] The beneficial effects of the present invention are:

[0025] The present invention uses the auxiliary positioning surface b on the right side of the horizontal correction connector as a reference and uses a feeler gauge to perform preliminary positioning of the right side of the horn mouth. The positioning accuracy is 0.01mm, the adjustment amount is accurate and controllable, and repeated manual and visual adjustments are avoided, shortening the calibration time to 25%.

[0026] The present invention standardizes the order and method of adjusting the 16 horn nozzles, eliminates the waste of time, personnel and materials in the repeated adjustment process, and reduces abnormal consumption and quality risks caused by product quality problems;

[0027] By cooperating with the adjustment seat and feeler gauge, the adjustment results of one set of bell mouths can be copied to the other 7 groups of 14 bell mouths, avoiding the time waste and inconsistent accuracy caused by the difficulty in controlling the adjustment amount by visual inspection and feel when calibrating one by one. The adjustment efficiency is improved and the adjustment time can be reduced from more than 4 hours to less than 40 minutes. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Example 1

[0039] like Figure 1-4 As shown,

[0040] A method for quickly correcting a double-track double-row rotating horn nozzle is provided for adjusting and correcting eight pairs of horn nozzles of a double-track double-row rotating horn nozzle; the method comprises the following steps:

[0041] S1, making a special tool; the special tool is provided with a surface a and a surface b perpendicular to each other; the surface a is in contact with the top surface of the trumpet mouth rotating arm;

[0042] S2, first adjust the relative position of a bell mouth and the cutting knife in the first group of the first row;

[0043] The step S2 includes the following steps:

[0044] S21, remove the bolt that secures the first set of two bell mouths and fix the special tooling on the rotating arm of the bell mouth;

[0045] S22, observe the level on the special tooling to ensure that the rotating arms of the two horn nozzles are on the same horizontal plane;

[0046] S23, loosen another bolt fixing the first set of horn nozzles so that the gap between the horn nozzles and the b-surface of the special tooling is 0.5 mm; then fix the bolt to the horn nozzle rotating arm;

[0047] S24, paint the blade with color, rotate the cutting blade, and observe the fit between the two sides of the blade and the bell mouth; if the right side of the blade fits the corresponding cutting blade of the cutter disc, and there is a 0.5mm gap on the left side, it is qualified, otherwise readjust;

[0048] S25. After the bell mouth and the blade are properly adjusted, remove the special tooling, then install the second bolt on the bell mouth and the adjustment is complete.

[0049] S3, using a dedicated tool, adjusting the second horn mouth in the first group of the first row based on the horn mouth in step S2;

[0050] S4, repeat steps S2 and S3, and adjust the remaining three rows of horn mouths in sequence.

[0051] In step S22, the levels of the two rotating arms of the horn mouth are fixed so that a 0.01 mm thick feeler gauge cannot be inserted into the gap between the special tooling and the rotating arms of the horn mouth.

[0052] In step S23, when the blade is rotated, if the blade cannot pass through the bell mouth, the blade is reversed and cannot be forced to pass through, and the position of the bell mouth is readjusted.

[0053] Operation steps of the present invention

[0054] 1. When in use, install the adjustment seat 5 of the trumpet mouth and the double-row rotating trumpet mouth rotating arm 9 together, and replace the trumpet mouth 7 installation screws and washers that need to be positioned with the first positioning bolts and positioning washers provided by the tooling.

[0055] 2. Use a feeler gauge to preliminarily position the right side of the bell mouth (7) on the side of the adjustment base (5) closest to the bell mouth, where the blade first contacts it. Simultaneously, use the parallelism calibration rod (8) on the bell mouth (7) to check the height and parallelism of the bell mouth guide groove and the tobacco rod channel. Remove the calibration rod (8) after checking and calibrating.

[0056] 3. Record the position and dimensions of the gaps between the right end of the bell mouth rotating arm 9 and the right end surface of the bell mouth 7 and the adjustment seat 5 respectively.

[0057] 4. Enlarge the gap between other horn nozzles to avoid contact between the horn nozzles and the corresponding cutters.

[0058] 5. Operate the equipment and check the contact between the horn nozzle and the cutting blade. If it does not meet the requirements, use a feeler gauge to control the gap between the horn nozzle and the adjustment seat according to the gap distance to accurately control the adjustment amount of the horn nozzle 7.

[0059] 6. After the adjustment is completed, remove the adjustment seat 5 and repeatedly calibrate the contact between the cutter and the trumpet 7. After the gap meets the requirements, use the adjustment seat 5 as a reference and use a feeler gauge to copy the adjusted gaps at positions 1 and 2, and copy the position of the next group of double-row trumpets.

[0060] 7. Run the equipment again to check the clearance adjustment effect between the cutter and the 16 bell mouths. If there is any problem, install the adjustment seat 5 again and make precise adjustments with a feeler gauge.

[0061] Example 2

[0062] The structure of this embodiment is basically the same as that of embodiment 1.

[0063] The difference is that, Figure 1 As shown,

[0064] A special tool includes an L-shaped adjustment seat; a finely machined surface a is provided on the top edge of the adjustment seat, and a finely machined surface b is provided on the side edge of the adjustment seat; the surface a is perpendicular to the surface b; and the surface a is in close contact with a horn mouth fixing arm.

[0065] The fixed arm is fixedly connected to the trumpet mouth by two bolts; a strip hole is provided on the top edge of the adjustment seat, and the diameter of the strip hole is larger than the diameter of the bolt.

[0066] Remove one bolt that fixes the horn mouth, and use the first bolt and washer to fix the A surface of the adjustment seat to the horn mouth fixing arm.

[0067] The working principle of the present invention is basically the same as that of Example 1, and will not be described in detail.

[0068] Example 3

[0069] The structure of this embodiment is basically the same as that of embodiment 1.

[0070] The difference is that

[0071] like Figure 3 As shown, the servo motor directly drives the bell mouth mechanism via the motor shaft, achieving its operation. An eccentric wheel 1, mounted on the servo motor's main shaft, drives a crank connecting rod, which drives the bell mouth holder to achieve reciprocating motion. When the eccentric wheel 1 rotates in the direction of the arrow, the crank connecting rod pushes the bell mouth holder 3, along with the bell mouth, to reciprocate. The bell mouth holder 3 is supported by two vibrating plates 4.

[0072] The working principle of the present invention is basically the same as that of Example 1, and will not be described in detail.

[0073] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions. The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
