Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a calibration device for a dual-channel cigarette receiving wheel movable arm. Background Technology

[0002] In existing technologies, dual-flue smoke receiving wheels employ a combination of movable and fixed smoke grooves, resulting in a relatively complex structure. Specifically, refer to... Figure 1 As shown, the receiving wheel 01 has multiple fixed smoke slots 011 and multiple movable arms 02 distributed at intervals along its own axis. There is a movable arm 02 between each two adjacent fixed smoke slots 011. The movable arm 02 can be swayed on the receiving wheel 01. The movable arm 02 has a movable smoke slot 021. The multiple fixed smoke slots 011 and multiple movable smoke slots 021 are evenly distributed at intervals along the axis of the receiving wheel 01.

[0003] In the prior art, to prevent smoke throwing from the smoke receiving wheel 01, the position of its movable arm 02 needs to be calibrated to correspondingly calibrate the position of the movable smoke groove 021. A tooling bracket 03 and a dial indicator 04 need to be installed, and a specification test mandrel is placed in each movable smoke groove 021. The specific calibration process is as follows: three specification test mandrels are placed in two fixed smoke grooves 011 and one movable smoke groove 021, with the movable smoke groove 021 located between two adjacent fixed smoke grooves 011. The movable smoke groove 021 with the specification test mandrel is positioned under the measuring head of the dial indicator 04. The smoke receiving wheel 01 is rotated until the position of the movable smoke groove 021 to be set reaches the cam apex of the measuring head, at which point the dial indicator 04 displays the minimum value. If the reading of the dial indicator 04 does not meet the requirements, the position of the movable arm 02 needs to be adjusted accordingly until the requirements are met, and then the movable arm 02 is fixed again, thus completing the calibration. However, with the above method, when there are too many movable arms 02 that need to be calibrated in the smoke receiving wheel 01, the tooling bracket 03 and dial indicator 04 need to be installed every time a movable smoke trough 021 is calibrated. This is time-consuming, labor-intensive, and has low calibration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a calibration device for a dual-flue smoke receiving wheel movable arm, which has a simple structure and effectively improves calibration efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A dual-channel cigarette receiving wheel movable arm calibration device is used for a cigarette receiving wheel. The cigarette receiving wheel has multiple fixed cigarette slots and multiple movable arms spaced apart along its own axial direction. A movable arm is provided between every two adjacent fixed cigarette slots. The movable arm is swayably mounted on the cigarette receiving wheel. Each movable arm has a movable cigarette slot. The multiple fixed cigarette slots and multiple movable cigarette slots are evenly spaced along the axial direction of the cigarette receiving wheel. When multiple fixed cigarette slots jointly accommodate a cigarette, the circular trajectory formed by the axes of the multiple cigarettes is a reference line L. The dual-channel cigarette receiving wheel movable arm calibration device includes:

[0007] The calibration block has three calibration holes spaced apart. The calibration holes on both sides correspond to the two fixed smoke slots, and the calibration hole in the middle corresponds to the movable smoke slot. The arc formed by the line connecting the axes of the three calibration holes is set to have the same radius as the reference line L.

[0008] Locking pins are provided one-to-one with the calibration holes, and the locking pins pass through the calibration holes to be fixedly inserted into the fixed smoke tray or the movable smoke tray.

[0009] Preferably, the device further includes a limiting member, which is fixed to one end of the locking pin facing away from the calibration block, and the limiting member is used to limit the penetration of the locking pin.

[0010] Preferably, the limiting component includes a nut, and the outer peripheral wall of the end of the locking pin facing away from the calibration block is provided with an external thread, and the nut is screwed into the external thread.

[0011] Preferably, the outer peripheral wall of the locking pin is provided with an external thread, and the inner peripheral wall of the calibration hole is provided with an internal thread, and the locking pin and the calibration hole are screwed together by the external thread and the internal thread.

[0012] Preferably, the diameter of the calibration hole is set to 8 mm.

[0013] Preferably, the length of the calibration block is set to 70mm, the height to 15mm, and the thickness to 20mm.

[0014] Preferably, the calibration block is configured as a rectangular hexahedron structure.

[0015] Preferably, the fit between the calibration hole and the locking pin is a transition fit.

[0016] Preferably, the calibration block has chamfers or rounded corners between two adjacent end faces.

[0017] Preferably, the calibration block is made of stainless steel.

[0018] Beneficial effects:

[0019] The dual-flue smoke receiving wheel movable arm calibration device provided by this utility model involves placing a calibration block on the outside of the smoke receiving wheel, with the two calibration holes on both sides of the calibration block aligned with the two fixed smoke slots. Locking pins are then inserted into the two calibration holes, passing through the corresponding calibration holes and securing them into the corresponding fixed smoke slots. After inserting the two locking pins on both sides, a locking pin corresponding to the middle calibration hole is inserted, passing through the calibration hole and extending into the side corresponding to the movable smoke slot. Since the arc formed by the axis connecting the three calibration holes has the same radius as the baseline L, the position of the middle locking pin corresponds to the reference position of the movable smoke slot. Based on the position of this locking pin, the position of the movable arm between the two fixed smoke slots is adjusted so that the movable arm moves to a state where the middle locking pin is securely inserted into the movable smoke slot and abuts against the inner wall of the movable smoke slot. This calibrates the movable arm to the reference position. The movable arm is then fixed, completing the calibration process. This device can quickly and easily calibrate the position of the movable arm, thereby adjusting the position of the movable flue. It eliminates the need for tooling brackets and dial indicators and frequent disassembly and assembly work. Its simple structure effectively improves calibration efficiency.

[0034] Reference Figures 2 to 4 As shown, this embodiment provides a dual-channel cigarette receiving wheel movable arm calibration device for a cigarette receiving wheel 01. The cigarette receiving wheel 01 has multiple fixed cigarette slots 011 and multiple movable arms 02 spaced apart along its own axial direction. A movable arm 02 is provided between every two adjacent fixed cigarette slots 011. The movable arm 02 is swayably mounted on the cigarette receiving wheel 01. The movable arm 02 has a movable cigarette slot 021. The multiple fixed cigarette slots 011 and the multiple movable cigarette slots 021 are evenly spaced along the axial direction of the cigarette receiving wheel 01. When the multiple fixed cigarette slots 011 jointly accommodate a cigarette, the circular trajectory formed by the axes of the multiple cigarettes is the baseline L.

[0035] The dual-flue smoke receiving wheel movable arm calibration device includes a calibration block 1 and a locking pin 2. The calibration block 1 has three calibration holes 11 spaced apart. The calibration holes 11 on both sides correspond to the two fixed smoke slots 011, and the calibration hole 11 in the middle corresponds to the movable smoke slot 021. The arc formed by the axis connecting the three calibration holes 11 is set to have the same radius as the baseline L. The locking pin 2 is set to correspond one-to-one with the calibration holes 11, and the locking pin 2 passes through the calibration holes 11 to be fixedly inserted into either the fixed smoke slot 011 or the movable smoke slot 021.

[0036] In this embodiment, when the dual-channel smoke receiving wheel movable arm calibration device is in use, the calibration block 1 is placed on the outside of the smoke receiving wheel 01, so that the two calibration holes 11 on both sides of the calibration block 1 are respectively aligned with the two fixed smoke grooves 011. Then, locking pins 2 are inserted into the two calibration holes 11 respectively. After the locking pins 2 on both sides are inserted, the locking pin 2 corresponding to the middle calibration hole 11 is inserted. This locking pin 2 passes through the calibration hole 11 and extends into the side corresponding to the movable smoke groove 021. Since the arc formed by the axis connecting the three calibration holes 11 is set with the same radius as the reference line L, the position of the middle locking pin 2 corresponds to the reference position of the movable smoke tray 021. Therefore, the position of the movable arm 02 between the two fixed smoke trays 011 is adjusted according to the position of the locking pin 2, so that the movable arm 02 moves to a state where the middle locking pin 2 is fixedly inserted into the movable smoke tray 021 and tightly abuts against the inner wall of the movable smoke tray 021. That is, the movable arm 02 is calibrated to the reference position. Then, the movable arm 02 is fixed, completing the calibration of the movable arm 02. This device can quickly and conveniently calibrate the position of the movable arm 02, thereby adjusting the position of the movable smoke tray 021, eliminating the need for the tooling bracket 03 and dial indicator 04 and frequent disassembly and assembly. Its simple structure effectively improves calibration efficiency.

[0037] For example, this calibration device is applied to the PROTOS-M8 dual-flue receiving drum 01. After measurement and data consultation, the diameter of the circle containing the fixed smoke groove 011 of the PROTOS-M8 dual-flue receiving drum is found to be 306mm, which is the diameter of the circle corresponding to the baseline L. The PROTOS-M8 dual-flue receiving drum 01 has 18 movable smoke grooves 021 and 18 fixed smoke grooves 011; therefore, the central angle of the arcs containing adjacent fixed smoke grooves 011 and movable smoke grooves 021 can be calculated to be 10°. After calculation using the arc formula, the arc of the circle containing adjacent fixed smoke grooves 011 and movable smoke grooves 021 of the PROTOS-M8 is confirmed to be 8.5π.

[0038] Preferably, the diameter of the calibration hole 11 is set to 8 mm.

[0039] Preferably, the length of calibration block 1 is set to 70mm, the height to 15mm, and the thickness to 20mm.

[0040] Preferably, the distance between the calibration hole 11 on one side and the corresponding side edge of the calibration block 1 is 8.43 mm.

[0041] Preferably, the circular spacing between the two calibration holes 11 located on both sides is 53.14 mm.

[0042] Preferably, the distance between the calibration hole 11 on one side and the bottom edge of the calibration block 1 is 6.34 mm.

[0043] Preferably, the height difference between the circle of the calibration hole 11 located in the middle and the calibration hole 11 located on the side is 2.32 mm.

[0044] As an optional implementation, the dual-flue smoke receiving wheel movable arm calibration device also includes a fixed plate 4, which is fixedly connected to the smoke receiving wheel 01. The fixed plate 4 and the smoke receiving wheel 01 are coaxially arranged. The fixed plate 4 has multiple first through holes and second through holes. The multiple first through holes correspond one-to-one with the positions of multiple fixed smoke slots 011, and the multiple second through holes correspond one-to-one with the positions of multiple movable smoke slots 021 in the calibration state. Specifically, the arc formed by the axis connecting the multiple first through holes and the multiple second through holes is set to have the same radius as the reference line L. The fixed plate 4 is fixedly set on the outside of the smoke receiving wheel 01, and then the calibration block 1 is placed on the outside of the fixed plate 4. The two calibration holes 11 on both sides of the calibration block 1 are not only set directly opposite to the two fixed smoke slots 011, but also correspond to the two first through holes. Locking pins 2 are inserted into the two calibration holes 11 respectively. The locking pins 2 pass through the corresponding calibration holes 11 and the first through holes and are then fixedly inserted into the corresponding fixed smoke slots 011. Insert the locking pin 2 into the middle calibration hole 11. The locking pin 2 passes through the calibration hole 11 and the second through hole and extends into the side corresponding to the movable smoke tray 021. The setting of the fixing plate 4 can ensure a more reliable connection between the calibration block 1 and the smoke receiving wheel 01.

[0045] In this embodiment, a limiting member is also included. The limiting member is fixed to one end of the locking pin 2 facing away from the calibration block 1, and is used to limit the passage of the locking pin 2. Optionally, the limiting member includes a nut 3. The outer peripheral wall of the end of the locking pin 2 facing away from the calibration block 1 is provided with an external thread, and the nut 3 is screwed into the external thread. The internal thread of the nut 3 is screwed into the external thread of the locking pin 2, so that the nut 3 can be fixed on the locking pin 2.

[0046] In some alternative embodiments, the outer peripheral wall of the locking pin 2 is provided with external threads, and the inner peripheral wall of the calibration hole 11 is provided with corresponding internal threads. The locking pin 2 and the calibration hole 11 are screwed together by the external and internal threads. In this embodiment, the nut 3 is omitted. By screwing the locking pin 2 into the calibration hole 11 through the threaded engagement between the locking pin 2 and the calibration hole 11, the locking pin 2 can be extended or retracted within the calibration hole 11.

[0047] In this embodiment, the calibration block 1 is configured as a rectangular hexahedron structure. This configuration results in a simple structure and convenient manufacturing.

[0048] Optionally, the fit between the calibration hole 11 and the locking pin 2 is a transition fit. This configuration ensures that the locking pin 2 can slide and extend smoothly within the calibration hole 11.

[0049] Optionally, chamfers or rounded corners are provided between two adjacent end faces of calibration block 1. This design can prevent sharp points from appearing between two adjacent end faces of calibration block 1, thus avoiding injury to the operator's hand.

[0050] Optionally, calibration block 1 is made of stainless steel. This design gives calibration block 1 good strength, wear resistance, and corrosion resistance.

[0051] In summary, the dual-flue smoke receiving wheel movable arm calibration device provided in this embodiment has a simple structure, effectively improves calibration efficiency, effectively solves the problem of long troubleshooting time for the smoke receiving wheel 01, and reduces downtime; it effectively improves work efficiency, meets the energy-saving and consumption-reducing requirements of the workshop, and has achieved significant results in practice.
