Abstract
The invention discloses a long straight cylindrical helical spring type powder conveying piece, which relates to the technical field of parts of a duplicating machine. The main parts for conveying the carbon powder in the conventional duplicating machine are all long bolt type parts, based on multiple helical surfaces outside the body of the bolt, each long bolt type part rotates around an axis to push the powder and conveys the powder in a powder box to a further powder utilization place. But the long bolt type parts also have too many defects. The invention uses a long straight cylindrical helical spring, which has large length-width ratio and rectangular cross section, as the powder conveying piece, wherein the plane of a long side of the rectangular cross section of the belt material is similar to the helical surface on the long bolt structure, when the helical spring rotates, the powder conveying piece has the same function of pushing and conveying the powder, but the powder conveying piece has a simpler structure, is very easy to produce and process, and can realize high-speed manufacturing, moreover, a hollow inner bore has no bolt body, the powder conveying piece can be more light, the material consumption is relatively low, and the cost (including manufacturing) is reduced obviously.
Description
Technical field
The invention discloses a kind of long straight cylinder helical spring type powder transmission parts, relate to duplicating machine parts technical field.
Background technology
Be used to carry that the critical part of carbon dust powder structure is provided is the long bolt formula in the existing copy (containing the part printer); Thereby the numerous helicoids that rely on the screw rod shaft to be uniformly distributed with arrangement outward produce push effect around screw axis rotating screw face in suitable duplicating machine transmission pipe inner chamber pipe hole; Powder is sent to the powder of using far away from powder box, but its processing and manufacturing difficulty of the long bolt of band helicoid, material consumption is more relatively; Cost is higher, and weight is also heavier relatively.
Summary of the invention
The object of the invention is to provide a kind of long straight cylinder helical spring type powder transmission parts; It adopts the spring silk is the long straight cylinder volute spring replacement long bolt spiral Transmission Part of aspect than rectangular cross section, and the side, place, long limit of its spring silk ribbon material square-section forms and is similar to the helicoid on the long bolt, when the straight cylinder volute spring pivots, has identical powder transmission effect; But its structure is more simple; It is very easy that processing becomes, and can realize making at a high speed, and weight is lighter; Material consumption is few, and cost can obviously descend.
The present invention adopts following technical proposals to realize:
A kind of long straight cylinder helical spring type powder transmission parts; Comprise a plurality of helicoids that are uniformly distributed with along powder transmission axis direction; It is characterized in that: adopting the spring silk is that the straight cylinder volute spring of rectangular cross section is as the powder transmission parts; Wherein the position, long limit at spring silk rectangular cross section place should be in the direction of near vertical in straight cylinder volute spring axis in the straight cylinder volute spring, and the described helicoid that is uniformly distributed with along powder transmission axis direction is alternative by the side at place, straight cylinder volute spring spring silk rectangular cross-sectional face length limit; The straight cylinder volute spring is constant pitch and should leaves between the adjacent two spring silk rectangular cross sections arbitrarily and hold the powder gap; Straight cylinder volute spring two ends endoporus inserts one respectively with suitable cylindrical mandrel one segment length of endoporus and be connected mutually with it.
The length of described cylindrically coiled spring square-section is between the 4.2-5.4 millimeter, and wide is between the 0.8-1.2 millimeter.
Described cylindrically coiled spring length overall is between the 400-420 millimeter.
Described cylindrically coiled spring endoporus is between the 5.5-6.5 millimeter.
Described cylindrically coiled spring is a constant pitch, and pitch is between the 18--22 millimeter.
Description of drawings
Accompanying drawing is the front view (complete section) and the right view of structure of the present invention.
1. straight cylinder volute springs among the figure, 2. cylindrical mandrel is 3. carried the circular hole pipe.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with accompanying drawing and concrete preferred embodiment the present invention is described further.
Referring to accompanying drawing, this preferred embodiment---a kind of long straight cylinder helical spring type powder transmission parts.Its structure is extremely simple; Its adopts straight cylinder volute spring 1 that aspect grows up than the direct coiling of the spring silk ribbon material of rectangular cross section as the powder transmission parts; The spring of noting the coiling moulding should guarantee that the position at its place, rectangular cross-sectional face length limit should be in the direction (to form bigger powder push helicoid) of near vertical in straight cylinder volute spring 1 axis; It can be formed by the side at place, straight cylinder volute spring 1 spring silk ribbon material rectangular cross-sectional face length limit along the helicoid that powder transmission axis direction is uniformly distributed with; Notice that the straight cylinder volute spring is constant pitch and should leaves between the adjacent two spring silk rectangular cross sections arbitrarily and hold the powder gap; Bigger spring pitch also promptly should be arranged, can not be also tight; Wherein straight cylinder volute spring 1 two ends endoporus inserts one respectively with suitable cylindrical mandrel one segment length of endoporus and be connected mutually with it and (adopt soldering to be connected to; Like copper or tin soldering), in this two cylindrical mandrel 2, a power input that is used for motor connects the double back shaft of doing spring one end; Another root is used for the rotation back shaft of the straight cylinder volute spring other end; For this reason, obvious two cylindrical mandrels, 2 planforms can be different, as long as suitable with respective ends purposes and functional requirement.
Advise that described straight cylinder volute spring 1 rectangular cross-sectional face length is between the 4.2-5.4 millimeter, wide is between the 0.8-1.2 millimeter; Described straight cylinder volute spring 1 length overall is between the 400-420 millimeter; Described straight cylinder volute spring 1 endoporus is between the 5.5-6.5 millimeter; Described straight cylinder volute spring 1 is a constant pitch, and pitch is between the 18--22 millimeter.As preference, straight cylinder volute spring 1 parameter all can in above-mentioned numerical range.
Straight cylinder volute spring 1 is placed on duplicating machine and carries in the circular hole pipe 3; Because the face at place, the rectangular cross-sectional face length limit of straight cylinder volute spring 1 spring silk ribbon material has formed and the similar helicoid of screw spiral face; When 1 rotation of driven by motor straight cylinder volute spring, the helicoid of the straight cylinder volute spring 1 that powder promptly is rotated is pushed continuously to be delivered to and is used the powder place.
Because its structure essence of this spiral Transmission Part is exactly a long spring; Therefore structure is very simple, and it is very easy that processing becomes, and can realize making at a high speed; And because of being solid shaft but hollow endoporus in the middle of the Transmission Part unlike the common screw formula; Material consumption relatively still less, weight is also lighter, cost (also comprising manufacturing cost) can be lower.
