Technical Field

The utility model relates to a flexible coil stock blowing device, especially a balanced blowing device belong to material storage facilities technical field.

Background

According to the applicant, two driving devices are respectively arranged on two sides of a support of a conventional winding shaft for soft materials such as cloth materials, and because the two driving devices are difficult to synchronize under a common condition, two ends of the winding shaft are easy to be uneven when the winding shaft lifts the materials, and as a result, the tension on two sides of the materials is uneven when the materials are discharged, and the edges of the materials are easy to deviate.

Disclosure of Invention

The utility model aims to provide a: aiming at the defects in the prior art, the balance feeding device which has large storage capacity and can avoid excessive feeding and keep the two ends of the coil feeding barrel horizontal is provided.

In order to reach above mesh, the utility model discloses a balanced blowing device includes three-dimensional frame structure's fixed work or material rest, the one end both sides of fixed work or material rest have parallel vertical guide rail respectively, vertical guide rail constitutes the travelling pair with hanging the hook stock that just undertakes the coil stock axle in initiative chain and driven chain rear end respectively, fixed work or material rest supports to have and is located vertical guide rail top and both ends and links firmly the synchronizing shaft who pairs initiative sprocket and driven sprocket respectively, the front end of initiative chain is walked around behind the initiative sprocket and is connected with the vertical piston rod of fixing the driving cylinder on fixed work or material rest, driven chain's front end is walked around behind the driven sprocket and is connected with the counter weight of the form that dangles.

When the lifting device works, when a piston rod of the driving cylinder pulls the driving chain, the chain wheels at the two ends of the synchronizing shaft synchronously drive the driven chain wheels to rotate, so that the two ends of the coil shaft are lifted along the vertical guide rail by the driving chain wheels and the driven chain wheels synchronously, the lifted coil can be easily and freely pulled out, and the deviation caused by uneven tension on the two sides during discharging is avoided.

The utility model discloses further perfect is: the cross section of the vertical guide rail is rectangular, and the hook frame is provided with a rectangular cross section rail groove in sliding fit with the vertical guide rail.

Detailed Description

Example one

The balanced discharging device of this embodiment is as shown in fig. 1, and including the fixed work or material rest 1 of three-dimensional frame structure, the one end both sides of this fixed work or material rest 1 have parallel rectangular cross section vertical guide rail 2 respectively, and the vertical guide rail 2 of both sides constitutes the sliding pair with the hook 5 of hanging in initiative chain 3 and 4 rear ends of driven chain respectively, and hook 5 has the rectangular cross section rail groove with vertical guide rail sliding fit, and two hook 5 undertake the both ends of coil stock axle 6 respectively.

The fixed material rack 1 is supported by a bearing seat with a rotatable synchronizing shaft 9 which is positioned above the vertical guide rail 2 and two ends of which are respectively fixedly connected with a matched driving chain wheel 7 and a driven chain wheel 8, the front end of a driving chain 3 is connected with a vertical piston rod 11 which is fixed on a driving cylinder 10 on the fixed material rack 1 after bypassing the driving chain wheel 7, and the front end of a driven chain 4 is connected with a pendulous balance weight 12 after bypassing the driven chain wheel 8.

More specifically, the distance L from the connecting point of the rear ends of the driving chain 3 and the driven chain 4 and the hook frame 5 to the vertical projection plane of the axis of the synchronizing shaft is greater than the pitch circle radius R of the driving sprocket 7 or the driven sprocket 8, so that when the two ends of the material rolling shaft 6 of the material roll 13 are respectively born on the two hook frames 5, the material roll 13 naturally tends to approach the fixed material frame 1 due to the self-weight component force, which is helpful for ensuring the stability of the material roll during lifting.

The driving chain 3 and the driven chain 4 are the same length. The front end chain link of the driving chain 3 is hinged with the upper end of the vertical piston rod 11, and the front end chain link of the driven chain 4 is hinged with the upper end of the balance weight 12, so that the driving chain 3 and the driven chain 4 are convenient to connect, have the function of automatically adjusting the vertical acting force to a certain degree, and are favorable for avoiding the distortion of the driving chain 3 and the driven chain 4.

When the device is used, the coil stock which is not unpacked is directly rolled to the hook frame which is located at the lower position of the fixed material frame, the hook frame is adjusted to the height corresponding to the coil stock shaft by controlling the action of the piston rod of the driving cylinder, the coil stock is pushed to the position where the coil stock shaft is born by the hook frame (see figure 2), then the coil stock is lifted and suspended to the proper height (see figure 3), and the subsequent emptying operation can be carried out after the outer package is removed. No matter lifting or discharging is carried out, the synchronous shaft ensures that the chain transmission mechanisms at the two ends are always synchronous, so that the coil shaft is always in a horizontal state, the lifted coil can be easily and freely pulled out, and the deviation caused by uneven tension on the two sides during discharging is effectively avoided.

Practice shows that the discharging device adopting the embodiment has the following remarkable beneficial effects:

1) when the coil stock is fed, only rolling operation is needed, so that the heavy labor of manually lifting the coil stock is avoided;

2) the lifting is stable and reliable, and the coiling shaft is always in an ideal horizontal state no matter at the beginning of lifting, in the middle of lifting or at the stop of lifting;

3) the tension degree of the material edges at two sides is consistent during discharging, so that discharging deviation is avoided.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
