Description

Roller spacing adjustment device for machinery

technical field

The utility model relates to a spacing adjustment device, in particular to a mechanical roller shaft spacing adjustment device.

Background technique

There are many types of machinery that assemble rollers on the machine for conveying. For example, there is an autoleveler drawing frame, which is used to process cotton sliver. The dispersed cotton slivers are concentrated and uniform, and are conveyed out between the rollers, and synthesized into a single wide width cotton sliver. Finally, the slivers that have been combined into a single strip are sequentially wound and collected in a cotton bucket. When a cotton barrel is collected, the sliver is separated, and another cotton barrel continues to collect the aforementioned sliver that is constantly sent out. The aforementioned sliver is conveyed through several rollers during the conveying process, as shown in Figure 6, wherein a roller seat 50 is provided on both sides of one end of the machine table, and a support seat 51 is straddled on the roller seat 50, each The support seat 51 is concavely provided with a fork groove 52 at the lower end, and the fork groove 52 is used to straddle and slide along the roller shaft seat 50, and then cooperate with several bolts 53 to form the horizontal long holes (not labeled) provided by the support seat 51 in the longitudinal direction, The support base 51 is locked on the roller shaft base 50, the end of the bolt 53 passing through the fork groove 52 is screwed with a nut 531 for fastening and positioning, and each pair of corresponding support base 51 is located between the upper end of the fork groove 52 A roller shaft 40 is installed between the pivots, so that the sliver can be rotated through the roller shaft 40 and can be smoothly conveyed to the next process. However, the combined design of the aforementioned roller shaft 40 has the following disadvantages in use.

1. The parallelism between the rollers is not accurate. Since the fibers of the sliver are long and short, in order to ensure that the short-fiber sliver will not fall into the gap between the rollers during transportation, it is necessary to adjust the distance between the rollers before operation. The adjustment method is to loosen the bolts and cooperate with the mobile support seat to slide along the roller shaft seat to adjust the distance between the roller shafts. However, because each support base is individually adjusted, the two corresponding support bases cannot be displaced synchronously due to the sliding distance of the two corresponding support bases, so that the sliding distances are different, resulting in a discrepancy between the roller shafts. The parallelism cannot be accurate, and even the roller shaft is skewed, which affects the effect of conveying the sliver.

2. The operation speed is slow. Due to relying on visual and empirical judgment, force is applied to push the support seat. Therefore, it is not only laborious to push, but also time-consuming because the adjustment process is exclusively dependent on human judgment mode, so the operation speed is slow and the operation efficiency is not high.

The slider adjustment rod passes through the through hole and passes through the adjustment hole of the roller slider. The surface of the slot is different from the through hole. A toothed rack meshed with the adjusting gear is fixed on the top.

Both ends of the slider adjustment rod are wrenching heads with non-circular sections for wrenching by hand tools.

The slider adjustment rods pass through the adjustment holes of the roller sliders in a loose fit state, and the slider adjustment rods are aligned in the chute of each roller slider in order to wear a spacer ring and a fixed ring. Adjust the gear and wear a small spacer ring.

The roller seat is provided with a ㄇ-shaped shallow groove on the outer surface, and a ㄇ-shaped slot is expanded in the shallow groove, and a backing plate is locked between the slot and the rack.

The shallow groove is sealed with a side plate, and the side plate is provided with a fixed hole on the upper side for locking on the surface of the shallow groove, and a corresponding long hole is provided on the lower side corresponding to the insertion direction of the slider adjustment rod and the through hole. .

A barrier ring is installed in the long hole of the side plate towards the slotting direction, and one end of the barrier ring is cut into a double-plane entry slot to limit the clamping part of linear sliding. The center of the barrier ring is provided with an internal thread hole, and the roller The chute of the shaft slider is adjacent to the outside lock of the slider adjusting rod with a stop bolt, and the stop bolt lock is fastened and clamped in the barrier ring of the long hole.

The slotting direction is set on the outer surface of the roller seat.

The bottom surfaces of the two roller seats are fixed on the two sides of a bottom plate.

The utility model has the following advantages:

1. The adjustment is accurate, and there is no concern about parallelism deviation. Since the slider adjusting rod is connected to the adjusting gear and slides along the rack, and the slider adjusting rod is connected to the two roller shaft sliders, it is ensured that the roller shaft sliders must be displaced synchronously. Therefore, the adjusted parallelism of each roller must be highly accurate.

2. Easy to adjust. As long as the slider adjustment lever is operated, the displacement of the slider of the two rollers can be driven. The wrenching heads of the slider adjustment rod protrude from the roller shaft seat, so any outer side can be operated, and then cooperate with the meshing rotation of the adjustment gear and the rack, the operation is labor-saving and the adjustment is quite convenient.

3. Low cost. The utility model is a semi-automatic method, and the components such as the slider adjustment rod, the adjustment gear and the rack are simple to process and easy to manufacture. Therefore, the utility model can provide high-efficiency use effects at low cost and without increasing power energy, and has a good performance. practicality.

4. The utility model can be applied to the draw frame. Because the adjustment of the roller shaft is convenient and accurate, the sliver can be transported smoothly no matter whether the fiber is long or short, and the utility model can also be applied to other machines with wide applicability.
