Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery, and more specifically, to a vibrating trough balance adjustment device. Background Art

[0002] During the wire manufacturing process, the vibrating trough plays a role in loosening and transporting materials, and occupies a relatively large proportion in the production equipment.

[0003] Due to the unique three-body (trough body, balance frame, support) structure and rocker arm mechanism of the vibrating trough, its failure rate during operation is significantly higher than that of other conveying equipment. The core problem lies in the destruction of the balance. During the maintenance process, the adjustment of the balance is the core problem in repairing the vibrating trough.

[0004] The core of balance adjustment lies in the clearance adjustment of the three bodies (trough body, balance frame, support), which is the key point and difficulty in the balance adjustment work of the vibrating trough, and also the stage that takes the longest time in the whole process. The time required for the clearance adjustment of the three bodies of the vibrating trough is directly related to the length of the balance adjustment time.

[0005] Currently, the most commonly used method is to use means such as hydraulic forklifts, jacks, levers combined with manual labor as the power source for adjustment. This adjustment method is relatively crude and dangerous; using the method of stuffing gaskets as precision parts for clearance spacing adjustment, but the size of the gaskets usually cannot be set arbitrarily, and only suitable sizes can be found from the existing gaskets, and stepless adjustment cannot be achieved.

[0006] Therefore, how to provide an oil flowmeter transportation device that can achieve stepless adjustment, high safety, and does not damage the original structure of the vibrating trough has become a technical problem that needs to be solved urgently in this field. Summary of the Invention

[0044] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0045] According to Figures 2 to 6 As shown, the present invention provides a vibration trough balance adjustment device, including a trough fixing block 2 with a horizontal reference plane, a balance frame fixing block 3, and an adjustment assembly.

[0046] The trough fixing block 2 is installed on the side wall of the trough body 7 of the vibration trough, and the reference plane 4 of the trough fixing block is flush with the lower surface of the trough body 7; the balance frame fixing block 3 is installed on the side wall of the balance frame 9 of the vibration trough, and the reference plane 5 of the balance frame fixing block is flush with the upper surface of the balance frame 9.

[0047] The adjustment assembly is installed on the side wall of the support 8 of the vibration trough and cooperates with the reference plane 4 of the trough fixing block and the reference plane 5 of the balance frame fixing block to adjust the gaps between the support 8 and the trough body 7 and the balance frame 9 respectively.

[0048] Figure 1 FIG. is a side view of a conventional vibration trough in the prior art. Imitation rocker arm mounting holes are provided on both the trough fixing block 2 and the balance frame fixing block 3 so as to be directly installed in the mounting holes of the original rocker arm 10 during installation, avoiding repeated drilling and damaging the structure of the vibration trough.

[0049] Further, the adjusting assembly includes a bracket fixing block 1, a trough adjusting cam 21, a balance bracket adjusting cam 31, and an adjusting wheel set. The wheel surface of the trough adjusting cam 21 cooperates with the reference surface 4 of the trough fixing block, and the wheel surface of the balance bracket adjusting cam 31 cooperates with the reference surface 5 of the balance bracket fixing block. The adjusting wheel set is located between the trough adjusting cam 21 and the balance bracket adjusting cam 31 and drives the trough adjusting cam 21 and the balance bracket adjusting cam 31 to rotate respectively. Similarly to the above, the bracket fixing block 1 is also provided with a rocker arm imitation mounting hole 10. The trough adjusting cam 21 and the balance bracket adjusting cam 31 are respectively located on the horizontal two sides of the adjusting wheel set and are arranged corresponding to the mounting orientation of the original rocker arm 10. The main purpose is still to avoid repeated drilling. The wheel surface of the trough adjusting cam 21 always abuts against the reference surface at the lower end of the trough fixing block 2, and the wheel surface of the balance bracket adjusting cam 31 always abuts against the reference surface at the upper end of the balance bracket fixing block 3. The trough adjusting cam 21 serves as a supporting structure for supporting the trough 7 during the adjustment process.

[0050] Still further, the adjusting wheel set includes a first gear 11, a second gear 12, and a rocker handle 13; a rotating shaft 14 protrudes from the bracket fixing block 1. The axis of the first gear 11 is sleeved on the rotating shaft 14, and a gear shaft 15 protrudes outward from the axis of the first gear 11. The second gear 12 is rotatably sleeved on the gear shaft 15; the first gear 11 is in transmission connection with the trough adjusting cam 21, and the second gear 12 is in transmission connection with the balance bracket adjusting cam 31.

[0051] A first spline shaft sleeve 16 is further provided on the side wall of the gear shaft 15, a second spline shaft sleeve 17 is provided at the axis of the second gear 12, and the second spline shaft sleeve 17 is rotatably sleeved on the gear shaft 15. A toothed ring 18 capable of cooperating with the first spline shaft sleeve 16 and the second spline shaft sleeve 17 is provided on the rocker handle 13 to drive the first gear 11 and the second gear 12 to transmit respectively.

[0052] In this embodiment, the first gear 11 and the second gear 12 can be rotatably connected relatively through structures such as bearings. The toothed ring 18 on the rocker handle 13 can be in tooth engagement with the first spline shaft sleeve 16 and the second spline shaft sleeve 17 respectively, so as to realize the separate adjustment of the trough adjusting cam 21 and the balance bracket adjusting cam 31, effectively realizing the separate drive of the trough 7 adjusting mechanism and the balance bracket 9 adjusting mechanism, with simple operation and no need for frequent switching.

[0053] Still further, the transmission shaft of the trough adjusting cam 21 extends to the outside of the trough fixing block 2 and is connected with a trough driving gear 22. The trough driving gear 22 is in meshing transmission with the first gear 11; the transmission shaft of the balance bracket adjusting cam 31 extends to the outside of the balance bracket fixing block 3 and is connected with a balance bracket driving gear 32. The balance bracket driving gear 32 is in meshing transmission with the second gear 12, which can achieve high-precision adjustment, even stepless adjustment.

[0054] Furthermore, a groove positioning ratchet 23 is provided on the transmission shaft of the groove adjusting cam 21, and a balance frame positioning ratchet 33 is provided on the transmission shaft of the balance frame adjusting cam 31. Pawls 6 that cooperate with the groove positioning ratchet 23 and the balance frame positioning ratchet 33 are respectively provided on the bracket fixing block 1, so that the groove adjusting cam 21 and the balance frame adjusting cam 31 rotate unidirectionally. The unidirectional rotation directions of the groove adjusting cam 21 and the balance frame adjusting cam 31 are opposite. The adjustment directions of the first gear 11 and the second gear 12 are opposite, and the rotation directions of the two sets of gear trains are also different. This can enable the rocker to rotate in different directions when operating the two sets of adjusting structures, avoiding adjustment failure caused by operation errors. The locking after adjustment utilizes the self-locking of the ratchet, and the improvement of the adjustment accuracy depends on the number of teeth of the ratchet.

[0055] Furthermore, the bracket fixing block 1 has an L-shaped structure and is divided into inner and outer parts. The groove adjusting cam 21 is located inside the bracket fixing block 1, the groove driving gear 22 and the groove positioning ratchet 23 are located outside the bracket fixing block 1, and the three are connected by a transmission shaft. The balance frame adjusting cam 31 is located inside the bracket fixing block 1, the balance frame driving gear 32 and the balance frame positioning ratchet 33 are located outside the bracket fixing block 1, and the three are connected by a transmission shaft. A shallow groove 19 for the rotation of the groove adjusting cam 21 and the balance frame adjusting cam 31 is provided inside the bracket fixing block 1, preventing the adjusting mechanism from being too heavy and affecting the balance of driving.

[0056] Furthermore, the groove driving gear 22 is located at the inner end of the groove positioning ratchet 23, and the balance frame driving gear 32 is located at the outer end of the balance frame positioning ratchet 33. The two can drive in a staggered manner, avoiding the too high cooperation between the positioning ratchet and the pawl 6 and affecting the stability.

[0057] Furthermore, a spirit level for adjusting the levelness is provided on the bracket fixing block 1, and a scale ruler fixed based on the spirit level and perpendicular to the spirit level. By leveling the spirit level and then measuring with the scale ruler, the gap is calibrated, avoiding adding additional tools and improving convenience.

[0058] Furthermore, the lengths of the reference planes 4 of the groove fixing block and 5 of the balance frame fixing block on the horizontal plane are both greater than or equal to 30 cm. The main purpose is to give sufficient margin for the groove 7 and the balance frame 9 to move horizontally, avoiding excessive horizontal movement and losing support.

[0059] Adjustment process:

[0060] There are a large number of rocker arms 10 on the vibrating trough. When performing the leveling operation, at least one rocker arm 10 is removed from each of the four corners of the vibrating trough first, and then the support fixing block 1, the trough body fixing block 2, and the balance frame fixing block 3 are respectively installed in the original mounting holes of the support 8, the trough body 7, and the balance frame 9, and the leveling is carried out for the trough body fixing block 2 and the balance frame fixing block 3.

[0061] During the installation process, the cam surface of the cam is adjusted to a position away from the fixing block to reduce the resistance and facilitate the installation.

[0062] When starting the adjustment, the toothed ring 18 of the rocker arm 10 is sleeved outside the first spline shaft sleeve 16 of the first gear 11 to realize the drive with the first gear 11. For the forward rotation operation, the height of the trough body fixing block 2 is adjusted by the cam surface of the trough body adjusting cam 21 until it is adjusted to the appropriate height; then the toothed ring 18 of the rocker arm 10 is sleeved on the second spline shaft sleeve 17 of the second gear 12, and for the reverse rotation operation, the gap of the balance frame fixing block 3 is adjusted by the cam surface of the balance frame adjusting cam 31 until it is adjusted to the appropriate width.

[0063] Then the new rocker arm 10 is installed in place, and finally the vibrating trough balance adjusting device at the four corners is removed, and the new rocker arm 10 is installed at the positions lacking at the four corners, that is, the balance adjustment of the vibrating trough is completed.

[0064] In other embodiments, in order to facilitate observing the adjustment effect, a spirit level that can be adjusted horizontally is installed on the outer edge of the positioning part of the support 8. The end of the spirit level is hinged with a scale, and the distance from the upper edge of the support 8 to the lower edge of the trough body 7 and the distance from the lower edge of the support 8 to the upper edge of the balance frame 9 can be measured respectively with the scale. Observe while adjusting, which is more convenient to use.

[0065] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
