Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery, and more specifically, to a calibration and adjustment tool for the position of a dual-medium nozzle for cigarette feeding. Background Art

[0002] A dual-medium nozzle is a common nozzle for feeding in the field of cigarette technology. Its characteristic is that it can inject liquid material and air simultaneously. By using the impact of air on the liquid material, the ejected liquid material is in a mist state and has a certain flow rate and pressure.

[0003] In a cigarette making production line, one of the key application positions is in a drum feeder. The drum feeder realizes a rotary rolling motion through an external power drive. A large number of turning rakes are arranged on its inner wall for tumbling the accumulated tobacco material, and the dual-medium nozzle is installed at the end of the drum feeder for injecting the required ingredients into the drum.

[0004] Since tobacco has a certain humidity and oiliness, adhesion will be formed in the drum after long-term operation. Therefore, the dual-medium nozzle also needs to be disassembled, cleaned and maintained regularly. However, after the dual-medium nozzle is installed in place, its position and orientation need to be calibrated and adjusted. At present, there is no special tool to solve this problem, and it mainly relies on the way of manual adjustment - observation - re-adjustment to finely debug the nozzle, and the process is relatively cumbersome.

[0005] Moreover, the spraying during the adjustment process needs to be consistent with the normal working conditions. Due to different configured temperatures, there may also be certain safety risks. Therefore, using a special tool to improve the efficiency of calibration and adjustment is a technical problem that needs to be solved urgently. Summary of the Utility Model

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation on the present utility model and its application or use.

[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0031] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0032] According to Figures 1 to 3 As shown, the utility model provides a calibration and adjustment tool for the position of a dual-medium nozzle 4 for cigarette flavoring, which includes a magnetic base 1, a positioning sleeve 2 and several adjustment screws 3;

[0033] The magnetic base 1 is annular and is used to sleeved on the outer periphery of the installation position of the dual-medium nozzle 4 and adsorbed on the end wall of the drum 5; before disassembly, washing and maintenance, first install the magnetic base 1 on the end wall of the drum 5 for pre-positioning.

[0034] The rear end of the positioning sleeve 2 is fixed to the magnetic base 1, the front end of the positioning sleeve 2 extends axially, the inner diameter of the positioning sleeve 2 is larger than the maximum range of the offset angle of the dual-medium nozzle 4, and the length of the positioning sleeve 2 is greater than the length of the dual-medium nozzle 4; that is to say, the inner diameter and length of the positioning sleeve 2 are much larger than the swing range of the dual-medium nozzle 4 to provide sufficient space for adjusting the angle.

[0035] The wall of the positioning sleeve 2 is provided with several radially arranged screw holes, each adjustment screw 3 is installed in each screw hole, and each adjustment screw 3 is provided with a scale. By adjusting the screwing length of each adjustment screw 3, the orientation of the dual-medium nozzle 4 is adjusted. For easy observation, the scale on the adjustment screw 3 is set as a circularly distributed scale line, and multiple groups of numbers can be set at equal angles to facilitate reading data.

[0036] Further, for convenient operation, an adjustment knob is provided at the outer end of the adjustment screw 3 located on the positioning sleeve 2.

[0037] Still further, to prevent damage to the dual-medium nozzle 4, a flexible contact 7 is provided at the inner end of the adjustment screw 3 located on the positioning sleeve 2.

[0038] To facilitate observing the adjustment state of the inner adjustment screw 3, in a preferred embodiment, the positioning sleeve 2 is integrally provided in a hollow shape, such as a frame structure composed of only a horizontal beam and an annular beam.

[0039] To avoid too many operation steps for the adjustment screw, four to six groups of the adjustment screws 3 are arranged around the positioning sleeve 2, and at least two rows are arranged along the length direction of the positioning sleeve 2.

[0040] Further, four centering screws 6 are arranged in a cross distribution around the magnetic base 1, the centering screws 6 are provided with scales, and each centering screw 6 is used to determine the installation position of the dual-medium nozzle 4. The scales on the centering screws 6 are also set as circular scale lines, and multiple groups of numbers can be set at equal angles to facilitate reading data.

[0041] Further, similar to the working principle of the above adjustment screw 3, for ease of operation, an adjustment knob is provided at the outer end of the centering screw 6 located on the magnetic base 1, and a flexible contact 7 is provided at the inner end of the centering screw 6 located on the magnetic base 1 to prevent damage to the dual-medium nozzle 4.

[0042] Description of the working principle:

[0043] In the idle state, this tooling is in an idle state, not installed, and only maintained.

[0044] When the dual-medium nozzle 4 needs to be disassembled and cleaned, first stop the machine to perform a preliminary cleaning of the drum 5, and then adsorb the magnetic base 1 on the end wall of the drum 5 and put it outside the dual-medium nozzle 4.

[0045] First, adjust the centering screw 6 so that the four centering screws 6 are aligned with the tail end of the dual-medium nozzle 4 to determine the installation position.

[0046] Then, adjust the screwing-in amount of each adjustment screw 3 so that the inner end contacts of the respective adjustment screws 3 are aligned with the outer surface of the dual-medium nozzle 4, and a shape with a working form constraint of the dual-medium nozzle 4 jointly formed by the centering screw 6 and the adjustment screw 3 can be obtained.

[0047] Obtain and record the scale values of each centering screw 6 and adjustment screw 3, and then, without removing the magnetic base 1, loosen the centering screw 6 and the adjustment screw 3 to a sufficient state, and then remove the dual-medium nozzle 4. This can avoid the difficulty of removing the dual-medium nozzle 4 caused by the tooling.

[0048] After the disassembly and cleaning are completed, the magnetic base 1 is still adsorbed and installed on the end wall of the drum 5 without changing its position. Then, install the dual-medium nozzle 4. When the position of the dual-medium nozzle 4 needs to be fixed, first pre-tighten it appropriately, leaving an adjustment margin, and then adjust the centering screw 6 to the recorded state to determine the installation position of the dual-medium nozzle 4.

[0049] Then, adjust each adjustment screw 3 to the recorded state respectively. The adjustment screw 3 pushes the dual-medium nozzle 4 to swing to the original angle. After the adjustment is completed, lock the dual-medium nozzle 4 and remove the tooling, regardless of the order.

[0050] Start the machine for testing, observe the working state of the dual-medium nozzle 4, which can basically reach 90% of the original setting. Then, based on the post-adjustment state, manually fine-tune the angle of the dual-medium nozzle 4 to achieve the final high-precision adjustment.

[0051] The above process is more efficient, more accurate, and simpler than the process that solely relies on manual adjustment.

[0052] Although some specific embodiments of the present utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for the purpose of illustration and not for limiting the scope of the present utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model. The scope of the present utility model is defined by the appended claims.
