The tightening device of board-like feeding machine operation parts of the present utility model, comprise operation parts (1), last slide rail (2), rear-mounted installation (3), fastening screw (4), the slide plate (5) that matches with fastening screw, spring (6), glidepath (7), frame (8) and spring supporting plate (9), said operation parts (1) comprise chain, the frid bolt, said rear-mounted installation (3) comprises tail-gear spindle, tail sprocket, bearing seat and bearing, wherein go up slide rail (2), glidepath (7) and spring supporting plate (9) are fixed on the frame (8), rear-mounted installation (3) is located on the glidepath (7), last slide rail (2) is located at the bearing seat top of rear-mounted installation (3), it can only be moved on the length direction of slide rail, and fastening screw (4) passes frame (8) successively, spring supporting plate (9), spring (6), the bearing seat of slide plate (5) back and rear-mounted installation (3) pushes up mutually.
Preferably,
Said spring is a cylindrically coiled spring.
Said spring is the valute spring of big elastic force.
The tightening device of board-like feeding machine operation parts of the present utility model has following technique effect:
1) simple and reliable for structure, cost is low, does not take up space;
2) tension effects is good, adjusts easyly, has reduced wearing and tearing, has improved driving efficiency, has increased the service life of chain and sprocket wheel.
Description of drawings
Come the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is the structural representation of embodiment 2 of the present utility model;
The specific embodiment
Embodiment 1 is used for the stretching device of light, medium-sized apron feeder operation parts
As shown in Figure 1, the tightening device of the board-like feeding machine operation parts of present embodiment, comprise operation parts (1), last slide rail (2), rear-mounted installation (3), fastening screw (4), the slide plate (5) that matches with fastening screw, cylindrically coiled spring (6), glidepath (7), frame (8) and spring supporting plate (9), said operation parts (1) comprise chain, the frid bolt, said rear-mounted installation (3) comprises tail-gear spindle, tail sprocket, bearing seat and bearing, wherein go up slide rail (2), glidepath (7) and spring supporting plate (9) are fixed on the frame (8), rear-mounted installation (3) is located on the glidepath (7), last slide rail (2) is located at the bearing seat top of rear-mounted installation (3), it can only be moved on the length direction of slide rail, and fastening screw (4) passes frame (8) successively, spring supporting plate (9), cylindrically coiled spring (6), the bearing seat of slide plate (5) back and rear-mounted installation (3) pushes up mutually.
The stretching device working process of present embodiment is as follows:
By continuous rotation fastening screw (4), withstand the bearing seat of operation parts (1), cylindrically coiled spring constantly is compressed and produces enough thrust and pass to slide plate (5), slide plate (5) passes to the fastening screw of screw thread fit (4) with it to thrust again, fastening screw (4) bearing seat that withstands rear-mounted installation (3) moves it backward then, and make cylindrically coiled spring (6) obtain enough compression thrust, finally make operation parts (1) obtain the permanent thrust tensioning of spring; Even after using a period of time, chain has a small amount of elongation, the thrust of cylindrically coiled spring (6) also can automatic compensation, by its thrust rear-mounted installation (3) is passed on external slide rail, thereby is made operation parts (1) continue tensioning under the permanent thrust of spring; After compensation repeatedly, when the thrust of cylindrically coiled spring (6) was not enough, the compression that only needs once more by turn fastening screw (4) cylindrically coiled spring (6) to be transferred to setting just.This kind structure has guaranteed the chain of operation parts (1) and the sprocket wheel positive engagement of head device, wearing and tearing have been reduced, improved driving efficiency, increased the service life of chain and sprocket wheel, make the tensioning of board-like feeding machine operation parts obtain real constant pressure tensioning, it is very easy to adjust use, and convey materials was to the impact of operation parts (1), because rear-mounted installation (3) always can the displacement of continual front and back under the effect of spring force in the use during also minimizing was used simultaneously.This kind tightening device fastening screw (4) is rear-mounted in addition, deploys fully in the support body range of sizes, has reduced the space.
Embodiment 2 is used for the stretching device of heavy-duty plate feeder operation parts
As shown in Figure 2, the tightening device of the link of present embodiment, working process and light, medium-sized apron feeder identical, difference is the valute spring that spring (6) has become big elastic force, the thrust that thrust that valute spring produced and hydraulic ram are produced is suitable, practice uses proof can replace the mode of hydraulic ram tightening device fully, compares with it, and cost is lower, working service is simpler, easier promoting the use of.
