Description

A kind of chain connecting gear for chopsticks transmission

Technical field

The utility model belongs to mechanical field, the chopsticks tranmission techniques being related to during chopsticks processing or packaging etc. are processed, Refer in particular to the chopsticks connecting gear for chopsticks process equipment.

Background technology

During processing, packaging etc. are processed chopsticks, the continuous transmission one by one automatically of chopsticks is that realization is corresponding Chopsticks processing procedure mechanical automation necessity before topic, common chopsticks one by one automatic transmission mechanism mainly by hopper, transmission Mechanism, recovering hopper three parts.Wherein hopper encloses upper opening of bucket-shaped structure for four sides, and the two sides of hopper are mutual Parallel, the spacing between two sides is suitable with chopsticks length, front-back at least adjacent to bottom a part, gradually phase from top to bottom To drawing close, formed at distance from bottom minimum behind two and only hold the feed opening that single chopsticks pass through, feed opening lower section sets one section vertically Thickness only hold the blanking channel that a chopsticks pass through.The origin or beginning correspondence blanking channel lower end of connecting gear is arranged, at present Disclosed connecting gear mainly has two kinds of forms, and one kind is screw connecting gear, and another kind is belt conveyor structure.

Screw connecting gear generally comprises two driven rods for being provided with isometric helix groove, and two driven rods are parallel to each other and set Put, and helicla flute synchronous cross is aligned.Two driven rod synchronous axial systems of Motor drive, the rotation direction and spiral fluted of driven rod It is oppositely oriented；Helicla flute is laterally only capable of accommodating single chopsticks, when mouth under helicla flute is just to blanking channel, in blanking channel most under Fang Yigen chopsticks are fallen in helicla flute, horizontal to take on two driven rods.As driven rod rotates, helicla flute promotes chopsticks to put down forward Move, realize automatically delivering for chopsticks.

Belt conveyor structure generally comprises the closure of two length for being smaller than a chopsticks arranged in parallel and passes Band is sent, is driven respectively by two pairs of synchronous pulleys, each pair synchronous pulley includes an active synchronization belt wheel, and a driven synchronous pulley. Wherein, two active synchronization belt wheels and two driven synchronous pulleys are co-axially mounted respectively, synchronous axial system.The peace of the active synchronization belt wheel Dress axle intermittent rotary under dynamical system driving, one end of the conveyer belt is located at chopsticks bucket lower section, and the other end is located on rewinding case Side.The transmission belt surface is provided with the translot perpendicular to conveyer belt direction of transfer.The translot horizontal one on two conveyer belts One correspondence.It is only capable of accommodating a chopsticks in the translot.

Existing two kinds of chopsticks connecting gear identical shortcoming is：Chopsticks naturally fall in (translot or helicla flute) in groove, During chopsticks are passed pound, chopsticks are not clamped, it is easy to beat, sliding, come off, and transmission stability is not enough, particularly with chopsticks Sub- positional precision and stationarity have high demands situation, and existing chopsticks connecting gear is difficult to be suitable for.

Additionally, set thumb wheel by feed opening more than existing hopper to stir by the way of chopsticks to prevent chopsticks blocking in blanking Mouthful, but the problem that the thumb wheel many chopsticks to be prevented are stuck side by side, and for indivedual chopsticks are tilted into feed opening Situation, thumb wheel cannot play a role.It is additionally, since thumb wheel too small, adjustable chopsticks limited amount, if chopsticks of stirring scope Son is being blocked away from feed opening where some, then stirring to touch.

The content of the invention

The utility model purpose is the present situation for chopsticks connecting gear, using chain as transmission basis, is proposed a kind of The solution of chopsticks is transmitted in the way of resilient clamp, to ensure stability of the chopsticks in transmit process.

To realize in above-mentioned purpose, the technical scheme of employing described in the utility model is：A kind of chain for chopsticks transmission Connecting gear.

Including two closed loop conveyer chains arranged in parallel, two transfer bar synchronization actions, equidistantly pacify on conveyer chain Some holders are filled, the holder on two conveyer chains is laterally aligned one by one.Two holders of horizontal alignment clamp a chopsticks Son.

Further, the holder is molded by single elastic sheet metal symmetric curvature, and the holder is flat including bottom Straight section, symmetrical two sections of outside linkage sections, two sections of symmetrical medial shaft straight sections；Outside linkage section upper end and homonymy Medial shaft straight section upper end connects, and lower end is connected with bottom flat section with side.

Further, the outside linkage section upper end of the holder is connected with homonymy medial shaft straight section upper end rounding off. The outside linkage section lower end of the holder equally can be connected with side with bottom flat section with rounding off.

Further, the outside linkage section of the holder is one section of plane being obliquely installed, or alternatively, described The outside linkage section of holder can also be one section of curved surface.

Further, the holder is arranged on a holder installing plate, and holder installing plate is right with holder institute The a piece of outer plate of the section conveyer chain answered is connected firmly.

Further, installing hole is provided with the middle part of holder bottom flat section, holder installing plate is provided with screwed hole, is pressed from both sides Gripping member is fixed on holder installing plate by soket head cap screw.

Further, described every conveyer chain of chain connecting gear is supported by a pair of sprocket, and each pair sprocket wheel includes a drive chain Wheel and a driven sprocket.Two drive sprockets and two driven sprockets in two pairs of sprocket wheels are co-axially mounted respectively, and synchronous axial system. The installation axle of the drive sprocket unidirectional intermittent rotary under power drive, drives conveyer chain indexing transfer.Conveyer chain single is transported Dynamic distance is equal to one times of spacing of holder.

Further, the chain connecting gear includes the bracing frame being made up of left riser and right riser, conveyer chain be located at a left side, Between right riser, the upper edge of left and right riser is respectively provided with a supporting plate bar, and supporting plate bar flat segments height is between going on journey conveyer chain Holder medial shaft straight section top and bottom between.The height of the chopsticks being clamped in for control in holder.

The main beneficial effect of the utility model includes：1st, using chain as transmission parts, precision is higher, and works as short distance During transmission, chain lower section is without the need for supporting plate.2nd, elastic clamping pieces are adopted and replaces tank, chopsticks can be constituted effectively in transmit process Clamping, prevents chopsticks bounce, sliding, comes off.2nd, the supporting plate bar arranged by conveyer chain side adjusts the chopsticks clamped by holder Sub- height, simple structure and the fixed reliability of shifting.
