Abstract

The invention relates to a retractable conveying device. The retractable conveying device comprises a lateral-space-adjustable rack, wherein at least two retractable frames are laterally arranged on the rack, each retractable frame is composed of a plurality of connecting rods which are articulated end to end in a crossing manner, a support rod is respectively arranged between the articulated points of the upper parts of the adjacent two retractable frames, and a plurality of pulley mechanisms which rotate around the support rods are arranged between every two support rods. The retractable conveying device is of a retractable structure, the length of the retractable conveying device can be changed according to requirements, and the retractable conveying device is simple to operate and has high efficiency; moreover, the retractable conveying device is simple in structure, is low in cost, can improve the economic benefit and can satisfy the production requirements of various products; in addition, the whole device has large flexibility and can reach other production requirements through increasing or changing parts.

Description

Telescopic feedway

Technical field

The present invention relates to a kind of telescopic feedway.

Background technology

At present, conveyer commonly used mostly is belt conveyor on the market, can't 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 are higher, affect production efficiency.

Summary of the invention

In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of simple in structure, respond well telescopic feedway.

To achieve these goals, technical scheme of the present invention is: a kind of telescopic feedway, the adjustable frame of the transverse pitch that comprises, described frame is horizontally arranged with at least two expansion bracket, described expansion bracket is by cross-shaped end to end hinged the forming of several connecting rods, be provided with strut bar between the described adjacent two expansion bracket upside hinge-points, be provided with a plurality of pulley mechanisms that rotate around strut bar between described two strut bars.

Further, described pulley mechanism comprises two clamping plates, and described clamping plate one end is connected with strut bar by bearing, and described clamping plate downside offers the deep-slotted chip breaker that slides for another strut bar, be provided with several bearings between the described two clamping plate upsides, roll in order to object.

Further, described frame downside is provided with scroll wheel, laterally adjusts 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, efficient is high; Simultaneously, the present invention is simple in structure, and cost is low, can increase economic efficiency again, is fit to the multiple product Production requirement; In addition, the single unit system alerting ability is larger, can increase or change part and reach other Production requirements.

Fig. 2 is the birds-eye view of the embodiment of the invention.

Fig. 3 is the constitution diagram one of the embodiment of the invention.

Fig. 4 is the constitution diagram two of the embodiment of the invention.

Among the figure: 1-frame, 2-expansion bracket, 3-hinge, 4-pulley mechanism, 5-scroll wheel, 6-strut bar, 4-1-clamping plate, 4-2-bearing, 4-3-chute.

The specific embodiment

The present invention is further elaborated below in conjunction with drawings and Examples.

With reference to figure 1, a kind of telescopic feedway, the adjustable frame 1 of the transverse pitch that comprises, described frame 1 is horizontally arranged with at least two expansion bracket 2, described expansion bracket 2 is by several connecting rod 3 cross-shaped end to end hinged forming, with reference to figure 2, be provided with strut bar 6 between described adjacent two expansion brackets, the 2 upside hinge-points, be provided with a plurality of pulley mechanisms 4 that rotate around strut bar 6 between described two strut bars 6.In addition, for the resistance to overturning of expansion bracket 2, again hinged at two cross link, 3 middle parts.

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, described clamping plate 4-1 downside offers the deep-slotted chip breaker 4-3 that slides for another strut bar 6, be provided with several bearings 4-2 between the described two clamping plate 4-1 upsides, roll in order to conveying object.

In the present embodiment, described frame 1 downside is provided with scroll wheel 5, laterally adjusts spacing in order to frame 1, in addition, for the ease of fixing of integral body, can dynamic resistance mechanism be set at scroll wheel 5, so just can keep in process of production single unit system to fix.

The present embodiment principle of work is as follows: with reference to figure 1, this kind state is the use state, this moment pulley mechanism 4 state reference maps 3, fixture block is in horizontality, the strut bar 6 in the deep-slotted chip breaker 4-3 is fixed on arcuate end, the upper motion of transported substance bearing 4-2 thereon; 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 the hinge-point moving, at this moment, the strut bar 6 in the deep-slotted chip breaker 4-3 is got back to the arc initiating terminal, single unit system just is in collapsed state, sees Fig. 4 for details.

The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
