Description

A kind of novel first sheet and comprise the first band of this first sheet

Technical field

The utility model relates to the feeder technical field, is specifically related to a kind of first sheet and comprises the first band of this first sheet.

Background technology

The first band of feeder is to be formed by the bearing pin serial connection by a large amount of first sheets in the prior art, and the first sheet is divided into I type and II type usually.The forward and backward coupling end of I type first sheet is provided with and is respectively equipped with a connector portions and an interface portion, and as shown in Figure 1, the position, both sides along bandwidth direction that it is suitable for being arranged in the first band has whole effect of being with; The forward and backward coupling end of II type first sheet is provided with and is respectively equipped with two connector portions and two interface portion, as shown in Figure 3, it is usually placed on whole of first band, and both sides are then replenished concordant by I type first sheet, and common cooperation of I type first sheet and II type first sheet makes the first band constitute a continuous integral body.

The side that two kinds of first sheets are used for the support material is set to tabular usually, owing to the less effect of feed that causes of friction force of the first sheet of this structure and storeroom is not good enough.Someone is provided with protuberance by the side at first sheet support material and improves the feed effect, but this protuberance can have inhibition to the whereabouts of material when the first band turns to, thereby improvement effect is limited; In addition, because this series products of first band is to be made of numerous first blade units, numerous protuberance summations obviously increases the total weight of first band, when cost is increased, also can cause the consumption of power obviously to increase.

Summary of the invention

The purpose of this utility model provides and a kind ofly can improve the feed effect and to the first sheet of the without hindrance effect in whereabouts of material.

For achieving the above object, the utility model adopts following technical scheme: a kind of novel first sheet, coupling end and back coupling end before comprising, there is the preceding mounting hole that passes for the bearing pin that connects the place ahead first sheet at preceding coupling end place, there is the back mounting hole that passes for the bearing pin that connects rear first sheet at back coupling end place, it is characterized in that: the first sheet is positive and be provided with the interconnecting gangway of concave shape between preceding coupling end and back coupling end, and interconnecting gangway is the expansion shape from inside to outside.

As shown from the above technical solution, when the front of first sheet is provided with the interconnecting gangway of concave shape between preceding coupling end and back coupling end, the interconnecting gangway place not only can hold the material than small particle diameter, can also the propelling movement effect be arranged to material, thereby this interconnecting gangway can realize transporting the effect of material preferably; When first tape running during to revolution place, because interconnecting gangway is the expansion shape from inside to outside, the width of opening part that also is the interconnecting gangway cross-sectional plane is greater than its in-to-in width, therefore the material than small particle diameter that is contained in the interconnecting gangway place can glide in the effect of gravity and fall, can not be subjected to inhibition in the landing process of material, this first sheet has significantly improved the feed effect thus.

Another purpose of the present utility model provides a kind of first band that is made of above-mentioned first sheet, the strong and long service life of this first band impact resistance.

For achieving the above object, the utility model adopts following technical scheme: adopt compliant pin to be linked and packed between the back mounting hole of described the place ahead first sheet and the preceding mounting hole of rear first sheet.

After adopting compliant pin to be linked and packed, the zone that the first band is hit can produce certain deformation, and this distortion has absorbed the energy that collides; thereby protected the first band to avoid damage; thereby prolonged service life of first band, and improved the impact resistance of first band, ensured the normal operation of feeder.

The specific embodiment

Shown in Fig. 1～4, coupling end 10 and back coupling end 20 before the first sheet comprises, there is the preceding mounting hole 11 that passes for the bearing pin that connects the place ahead first sheet at preceding coupling end 10 places, there is the back mounting hole 21 that passes for the bearing pin that connects rear first sheet at back coupling end 20 places, the first sheet is positive and be provided with the interconnecting gangway 30 of concave shape between preceding coupling end 10 and back coupling end 20, and interconnecting gangway 30 is the expansion shape from inside to outside.

As preferred version of the present utility model, described interconnecting gangway 30 is parallel with forward and backward mounting

hole

11,21 along the bearing pin length direction.This be arrangeding in parallel is easy to processing, and the stress equalization when helping first sheet support material also helps material and falls in the integral body of revolution place.

Interconnecting gangway 30 can be realized by multiple scheme, such as adopting V word shape, circular-arc or fall echelon form.As preferred version of the present utility model, the cross-sectional plane of described interconnecting gangway 30 is circular-arc or falls echelon form.

Shown in Fig. 2,4,6, the cross-sectional plane of interconnecting gangway 30 is circular-arc.When material was dropped on the first band by feed hopper, because the cross-sectional plane of interconnecting gangway 30 is circular-arc, so each first sheet can hold the material of smaller particle size easily, promotes bigger material simultaneously and moves with the first band; When first tape running during to revolution place, owing to circular-arc connection makes the first sheet comparatively level and smooth everywhere, so material skids off the first sheet under the effect of gravity, thus the satisfactory course of conveying of finishing material.When the cross-sectional plane of interconnecting gangway 30 is when falling the echelon form, its action effect and above-mentioned comparatively similar, and circular-arc or the processing of falling the echelon form is comparatively convenient, be easy to realize.

As shown in Figure 5, adopt compliant pin 40 to be linked and packed between the preceding mounting hole 11 of the back mounting hole 21 of described the place ahead first sheet and rear first sheet.

Because the first band will be in the support material, also to often bear the impact that material falls to being caused, thereby the connection mode between the first sheet just becomes the key point of the normal operation of feeder, when the connecting bore of first sheet adopts the rigidity bearing pin to be linked and packed, it is stressed bigger when bearing the impact of material whereabouts, and the integral structure of first band is sustained damage.The utility model adopts compliant pin 40 to be linked and packed; when the first band is subjected to impacting; because of compliant pin 40 itself has certain elasticity; the zone that the first band is hit can produce certain deformation; this distortion has absorbed the energy that collides; thereby protected the first band to avoid damage, thereby prolonged the service life of first band greatly, ensured the normal operation of feeder.

As the utility model preferred version further, described compliant pin 40 is the flexible nylon pin.

The implementation of compliant pin 40 has multiple, and the utility model is selected the flexible nylon pin for use, the flexible nylon pin be convenient to make and cost low, be a kind of comparatively desirable raw MAT'L.

As the utility model another kind preferred version further, described compliant pin 40 is positioned at the diameter at two ends of first band bandwidth direction greater than the diameter of connecting bore.

Above-mentioned set-up mode can guarantee that the connection between the first sheet is comparatively firm, makes each first sheet serial connection as a whole, has improved the stability and the impact resistance of first tape running.
