Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.

As shown in fig. 1-4, the expanding and contracting motion of the novel uncoiler drum with the compensation device 4 is realized by pushing and pulling the main shaft 1 through the oil cylinder, the rotating motion is realized by driving the transmission gear 6 arranged on the hollow sleeve 5 to rotate through the transmission system in the uncoiler, and the principle is consistent with that of a conventional drum.

The application a take compensation arrangement 4's novel decoiler reel, main shaft 1 does not directly link to each other with the hydro-cylinder, designs connecting axle 9 device, and connecting axle 9 one end design is threaded, is connected with main shaft 1, is equipped with adjusting pad 8 between connecting axle 9 and the main shaft 1, and the accessible processing changes the thickness of adjusting pad 8 to the adjustment reel is because of the accumulated error that manufacturing produced, guarantees the expansion diameter and the corresponding relation of stroke of reel, and after the adjustment was accomplished, mounting pin 8 is with locking. The other end of the connecting shaft 9 is fixedly connected with an oil cylinder, and the oil cylinder drives the main shaft 1 to axially move by driving the connecting shaft 9 when expanding and contracting.

The application a take compensation arrangement 4's novel decoiler reel, main shaft 1 cubic all has indent main shaft inclined plane 15 and eave tile 16, for guaranteeing main shaft 1 intensity, main shaft 1 indent will misplace with vertical direction in the horizontal direction.

The novel uncoiler winding drum with the compensation device 4 has the advantages that the lining plate 3 is arranged on the inclined surface 15 of the main shaft, and the lining plate 3 is made of copper alloy materials and plays roles of wear resistance and lubrication.

The novel uncoiler winding drum with the compensation device 4 has the advantages that the inclined plane corresponding to the spindle 1 in the axial direction is arranged on the sector plate 2, and the inclined plane is of a T-shaped structure and can be hooked by the spindle hook head 16.

The application a take compensation arrangement 4's novel decoiler reel, sector plate 2 is radially spacing by hollow cover 5, through radial spacing to sector plate 2 to and sector plate 2 cooperatees with the main shaft inclined plane 15 that installs welt 3, converts the axial motion of main shaft 1 into the radial motion of sector plate 2, thereby realizes the expansion and contraction of reel, and this principle is unanimous with conventional reel.

The application a take compensation arrangement 4's novel decoiler reel, compensation arrangement 4 dress is on sector plate 2, now explains compensation arrangement 1 principle:

the compensation device 4 of this application, sector plate 2 has circular slot 19, circular slot 19 is perpendicular with sector plate 2 inclined plane, sector plate 2 is provided with waist type groove 17, there is a through-hole 18 in waist type groove 17 and circular slot 19, belleville spring 12 installs in circular slot 19, cardboard 11 is placed on belleville spring 12, T type key 13 installs in waist type groove 17, slide 3 is equipped with to T type key 13 both sides, adjusting bolt 10 passes cardboard 11, belleville spring 12 and through-hole 18, the spin closes on T type key 13, main shaft eave tile 16 hooks the T type key 13 that is equipped with slide 14, screw up adjusting bolt 10, ensure that belleville spring 12 is in compression state, and elasticity reaches the required value.

The principle of the compensation device 4 described in the present application is as follows: after the T-shaped key 13 is hooked by the main shaft hook head 16, the butterfly spring 12 is pressed by the adjusting bolt 10, so that the butterfly spring 12 generates elastic force, the elastic force is applied to the bottom plane of the circular groove 19 of the sector plate 1 and acts on the sector plate 2 to press the sector plate 2 on the main shaft 1, so that when the winding drum works, the inclined plane of the sector plate 2 and the inclined plane 15 of the main shaft provided with the lining plate 3 are in an ideal contact state at any time, and when the sector plate 2, the main shaft 1, the lining plate 3 and other parts are worn, a gap formed between the sector plate 2, the main shaft 1, the lining plate 3 and other parts is compressed by the butterfly spring 12 to compensate, and when the elasticity of the butterfly spring 12 is insufficient, the adjusting bolt 10 can be screwed more tightly, so that the elasticity of the butterfly spring 12 is larger.
