Telescopic feedway
Technical field
The present invention relates to a kind of telescopic feedway.
Background technology
At present, conveyer conventional mostly on the market is belt conveyor, cannot telescopic adjustment, during use, usually with changing belt conveyor or removing belt conveyor, therefore need the belt conveyor of plurality of specifications for subsequent use because of place reason or Production requirement, complex operation and cost is higher, affects production efficiency.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide the telescopic feedway that a kind of structure is simple, respond well.
To achieve these goals, technical scheme of the present invention is: a kind of telescopic feedway, the adjustable frame of the transverse pitch comprised, described frame is horizontally arranged with the expansion bracket of at least two, described expansion bracket hingedly end to end to form by several connecting rods are cross-shaped, be provided with strut bar between hinge-point on the upside of described adjacent two expansion brackets, between described two strut bars, be provided with multiple pulley mechanism rotated around strut bar.
Further, described pulley mechanism comprises two clamping plates, and described clamping plate one end is connected with strut bar by bearing, offers the deep-slotted chip breaker slided for another strut bar on the downside of described clamping plate, be provided with several bearings between on the upside of described two clamping plate, roll in order to object.
Further, on the downside of described frame, be provided with scroll wheel, laterally adjust spacing in order to frame.
The present invention has the following advantages: adopt stretching structure, can change its length according to production requirement, simple to operate, efficiency is high; Meanwhile, structure of the present invention is simple, and cost is low, can increase economic efficiency again, is applicable to multiple product Production requirement; In addition, single unit system alerting ability is comparatively large, can increase or change part and reach other Production requirements.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated.
With reference to figure 1, a kind of telescopic feedway, the adjustable frame 1 of the transverse pitch comprised, described frame 1 is horizontally arranged with the expansion bracket 2 of at least two, described expansion bracket 2 hingedly end to end to form by several connecting rods 3 are cross-shaped, with reference to figure 2, on the upside of described adjacent two expansion brackets 2, between hinge-point, be provided with strut bar 6, between described two strut bars 6, be provided with multiple pulley mechanism 4 rotated around strut bar 6.In addition, in order to the resistance to overturning of expansion bracket 2, again hinged in the middle part of two cross link 3.
In the present embodiment, with reference to figure 3, described pulley mechanism 4 comprises two clamping plates 4-1, described clamping plate 4-1 one end is connected with strut bar 6 by bearing 4-2, the deep-slotted chip breaker 4-3 slided for another strut bar 6 is offered on the downside of described clamping plate 4-1, be provided with several bearings 4-2 between on the upside of described two clamping plate 4-1, roll in order to conveying object.
In the present embodiment, be provided with scroll wheel 5 on the downside of described frame 1, laterally adjust spacing in order to frame 1, in addition, fixing for the ease of entirety, can arrange blocking mechanism, so just can single unit system be kept in process of production to fix on scroll wheel 5.
The present embodiment principle of work is as follows: with reference to figure 1, and this kind of state is using state, now pulley mechanism 4 state reference Fig. 3, and fixture block is in horizontality, and the strut bar 6 in deep-slotted chip breaker 4-3 is fixed on arcuate end, and transported substance bearing 4-2 thereon moves; When not needing this device, by packing up expansion bracket 2, regulate frame 1 transverse pitch, make connecting rod 3 reduce the spacing of adjacent supports bar 6 by hinge-point moving, now, the strut bar 6 in deep-slotted chip breaker 4-3 gets back to arc initiating terminal, single unit system is just in collapsed state, refers to Fig. 4.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
