Description

Technical Field

[0001] This utility model belongs to the field of tobacco processing technology and relates to a tooling for quickly adjusting the gap between the ink nozzle and the ink roller. Background Technology

[0002] Cigarette rolling machines are key pieces of equipment in tobacco processing, used to turn processed tobacco into standard-sized cigarettes. The label box (also known as the printing system) is an important component of the cigarette rolling machine assembly, its main function being to print trademark designs or embossed stamps on the cigarettes. Specifically, the label box completes the printing task by pulling the cigarette paper and feeding it into the cigarette gun at the same linear speed as the fabric belt.

[0003] However, when adjusting the gap between the ink nozzle and the ink roller of the cigarette rolling machine, a feeler gauge is needed to manually adjust the gap. It is difficult to achieve the standard value by manual adjustment, which not only affects production efficiency but also causes serious waste of manpower.

[0004] Therefore, a highly efficient and precise ink nozzle and ink roller gap adjustment device is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention aims to provide a tooling for quickly installing and adjusting the pressure roller. The standard circle diameter is determined by adding 0.05mm to the original ink roller diameter. This circle must be tangent to the arc of the ink nozzle. The arc surface of this circle in contact with the ink nozzle serves as the adjusting block. Two limit blocks (applicable to ZJ17 and ZJ118 cigarette machines respectively) limit the initial position of the adjusting block. A lifting and fine-tuning mechanism is designed, controlled by a 0.25mm pitch hexagonal screw. The screw is surrounded by graduations, divided into 25 divisions, with each rotation of the screw representing 0.01mm. To adjust the gap between the ink nozzle and the ink roller, simply ensure the ink nozzle is in concentric contact with this tooling and then tighten the ink nozzle cylinder screw.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a tooling for quickly adjusting the gap between the ink nozzle and the ink roller, comprising: a tooling body, the upper end of the tooling body is provided with a tooling mounting hole, the shape and size of the tooling mounting hole are the same as the shape and size of the mounting hole for the ink roller to be installed in the cigarette machine, the lower end of the tooling body is provided with an adjusting screw, the adjusting screw is rotatably connected to the tooling body, and the rotation axis of the adjusting screw is orthogonal to the rotation axis of the tooling mounting hole;

[0007] The upper end of the adjusting screw is threaded with a dial, which is fixedly connected to the fixture body. The upper end of the adjusting screw is marked with a line near the dial, and the lower end of the adjusting screw is rotatably connected to an adjusting block. The side of the adjusting block away from the fixture mounting hole is arc-shaped.

[0008] The side wall of the tooling body is provided with a limiting block, and the limiting block is provided with a mounting hole for connecting to the ink roller mounting hole of the cigarette machine brand box;

[0009] The radius of the arc surface of the adjustment block is the same as the radius of the ink roller;

[0010] In the initial position, the mark points to the 0 mark on the dial, and the distance from the curved surface of the adjustment block to the rotating shaft of the tooling mounting hole is equal to the radius of the ink roller.

[0011] Preferably, the upper end face of the adjusting screw is provided with an internal hexagonal hole.

[0012] More preferably, the marking is located on the periphery of the internal hexagonal hole.

[0013] Preferably, the limiting block is detachably connected to the tooling body.

[0014] More preferably, the tooling body has a slot on its side wall, and the limiting block is engaged in the slot.

[0015] Preferably, the tooling body is provided with a slide groove, and the adjusting block is slidably connected to the slide groove.

[0016] Preferably, in the initial position, the lower outer edge of the tooling body does not extend beyond the arc-shaped surface of the adjusting block.

[0017] Preferably, each graduation on the dial corresponds to an outward extension of 0.01 mm in the arc-shaped surface of the adjustment block.

[0018] The beneficial effects of this utility model are:

[0019] This invention transforms the traditional experience-based manual gap adjustment into a standardized operation of "scale quantization + mechanical positioning," which not only reduces the technical requirements for operators but also increases the efficiency of gap adjustment by more than three times, meeting the stringent requirements for ink supply precision during high-speed production of cigarette machines.

[0025] The relevant technologies of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] refer to Figures 1-4 As shown in the figure, the steps for using the tooling body 1 and the clearance adjustment operation in this specific embodiment are as follows:

[0027] I. Preparations before use

[0028] 1. Model confirmation and installation of limit block 3

[0029] - Confirm the cigarette machine model: ZJ17 or ZJ118, select the corresponding limit block 3 (the two have different external dimensions; the thickness of the limit block 3 for ZJ17 is 12mm, and for ZJ118 it is 15mm), insert it into the side of the tool body 1 through the slot, and fix it with M4 screws (torque 3-4N·m).

[0030] - Clean the surfaces of ink roller 6 and ink nozzle 7 to remove ink residue and dust, and prevent impurities from affecting the gap accuracy.

[0031] 2. Initial installation of tooling body 1

[0032] Place the fixture body 1 directly above the ink roller 6, align the limiting block 3 with the mounting hole of the sign box, and initially tighten the fixture fixing screws (M6, torque 5-8 N·m) to ensure that the fixture body 1 does not wobble but can be finely adjusted in position.

[0033] II. Specific Operations for Gap Adjustment

[0034] 1. Reference gap positioning

[0035] - Observe whether the mark 5 on the adjusting screw 4 points to the "0" position on the dial 2. At this time, the theoretical gap between the arc surface of the tooling adjusting block 9 and the ink roller 6 is 0.05mm (determined by the fact that the diameter of the tooling standard circle is 0.05mm larger than that of the ink roller 6).

[0036] If the mark 5 is not aligned with zero, the adjusting screw 4 needs to be manually rotated to align the mark 5 with the "0" mark on the dial 2 to ensure the accuracy of the initial reference.

[0037] 2. Fine-tuning of target gap

[0038] - Determine the target clearance based on process requirements (e.g., standard clearance is 0.08mm), and calculate the number of rotations required:

[0039] -Target clearance - Reference clearance = Adjustment required, i.e., 0.08mm - 0.05mm = 0.03mm;

[0040] - Each division corresponds to 0.01mm, so you need to rotate 3 divisions clockwise to make the mark 5 point to the scale "3".

[0041] - Slowly turn the adjusting screw 4 with an Allen wrench, paying attention to the gap (≥0.5mm) between the adjusting screw 4 and the dial 2 to avoid jamming. During the rotation, you can feel the contact force between the adjusting block 9 and the ink nozzle 7 by hand. When the arc surfaces of the two are in contact, the resistance to turning the wrench increases evenly.

[0042] 3. Gap verification and fixation

[0043] - Insert a 0.01mm feeler gauge between the ink nozzle 7 and the adjusting block 9. If the feeler gauge cannot be inserted, it means the gap is ≤0.01mm. If you need to verify the 0.08mm gap, you can use a 0.08mm feeler gauge to check. It should be able to be inserted slightly but without looseness.

[0044] - After confirming that the gap meets the requirements, tighten the cylinder bolt of ink nozzle 7 with a torque wrench (M8, torque 10-12 N·m) to ensure that the position of ink nozzle 7 is fixed.

[0045] III. Tooling Body 1: Dismantling and Final Inspection

[0046] 1. Dismantle the tooling body 1

[0047] - First, loosen the fixture fixing screws, and slowly remove the fixture body 1, being careful to avoid collision with the surface of the ink nozzle 7.

[0048] - Check if there is any ink residue on the arc surface of adjustment block 9. Wipe it clean with a lint-free cloth dampened with alcohol to prevent residual ink from affecting the accuracy of the next use.

[0049] 2. Run verification

[0050] - Start the cigarette machine and run it at low speed (500 cigarettes / minute). Observe whether the ink supply from the ink nozzle 7 to the ink roller 6 is uniform. A continuous ink film without breaks should be formed on the surface of the ink roller 6.

[0051] -After stopping the machine, use a dial indicator to measure the actual gap between the ink nozzle 7 and the ink roller 6: with the dial indicator contact against the edge of the ink nozzle 7, rotate the ink roller 6 one revolution, and the pointer fluctuation range should be ≤0.02mm, indicating that the gap is consistent.

[0052] In summary, this utility model transforms manual gap adjustment into a standardized operation of "scale quantization + mechanical positioning," which not only reduces the technical requirements for operators but also improves the efficiency of gap adjustment.

[0053] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
