Description

Tooth registration device

Technical field

The utility model relates to a kind of printing machinery, particularly a kind of tooth registration device that prints back equipment.

Background technology

In today of printing equipment high speed development, high accuracy, high-speed, high stability are that the whether good important indicator of printing equipment is judged by printing manufacturer always.Behind the seal of can the one-step print paper feed accomplishing cross cutting, gold stamping or useless clearly technology in the equipment; Paper drives many group tooth rows by chain and holds paper successively in the month with the track of closed circulation; And successively through gold stamping, cross cutting, useless clearly and collection station, because closed chain is longer, in long-term use; The trace stretching of each chain link accumulative total will make the amount of tension of whole piece chain increase, thereby influence the precision of equipment.Look into the Chinese patent database; One notification number is CN201792558U, and name is called the openly following content of utility model patent of " a kind of tooth registration device ": a kind of tooth registration device is characterized in that it is made up of chain locating piece, set screw, chain, contiguous block, tooth row body, back location fork and positioning roller; Said chain locating piece, set screw, chain, contiguous block, back location fork and the equal symmetry of positioning roller are installed on the both sides of tooth row body; Said contiguous block is connected on the chain, and said chain locating piece is positioned at directly over the chain link of the chain that is connected with contiguous block, and the chain locating piece is fixed on the fixture; Said positioning roller is the roller on the contiguous block chain link; The two ends of said tooth row body are fixedly connected on respectively on the contiguous block, and location, said back fork is symmetrical part, and can rotate around the O point; When swinging, one end of location, back fork contacts with the locating surface of locating piece; Realize the location, back, said set screw is installed on the chain locating piece, can finely tune the traffic direction of the chain of chain locating piece.The tooth registration device of this structure is to rely on the chain locating piece that chain is positioned, and relies on set screw that it is finely tuned, and has solved the chain stretching to a certain extent and has caused the not high problem of precision.But since it need be on machine mounting fixing parts, the chain locating piece is installed on fixture again, the installation accuracy of this chain locating piece also can have influence on positioning accuracy, simultaneously, its complex structure also takes up room, therefore, this regulative mode is desirable not enough.

Summary of the invention

In view of the deficiency that background technology exists, the technical problem that the utility model will solve provides a kind of simple in structure, the tooth registration device that positioning accuracy is high.

For this reason; The utility model adopts following technical scheme to realize: a kind of tooth registration device, have Connection Block, contiguous block, chain and back by rule, and said contiguous block is connected with said chain; Said Connection Block is connected with contiguous block through connecting pin; Said Connection Block is installed on the tooth row body, it is characterized in that said Connection Block is provided with adjustable alignment pin, and described back contacts with described alignment pin when swinging by rule.

Be with spring on the said connecting pin, said spring is positioned at the gap of said Connection Block and contiguous block.

This structure of the utility model is when tie rod produces the stretching phenomenon, as long as regulate alignment pin a little; Lean on to advise alignment pin and back contact after; Make Connection Block and back change, be tooth row and back and change, thereby effectively tooth row is carried out relative positioning with the back by rule by the distance between the rule by the distance between the rule; Put not in place and moulding is gold stamping, the problem of low precision during cross cutting to solve tooth ranking that chain stretching phenomenon brings, it is easy to adjust simple.

Description of drawings

Combine accompanying drawing to further describe the relevant details of the utility model below again.

Fig. 1 is the structure chart of the utility model;

Fig. 2 is the cutaway view of Fig. 1 along A-A.

The specific embodiment

With reference to accompanying drawing, this tooth registration device has Connection Block 7, contiguous block 3, chain 1 and back by rule 4; Described chain 1 is a closed loop chain; Said contiguous block 3 is connected with said chain 1, and said Connection Block 7 is connected with contiguous block 3 through connecting pin 2, is with spring 5 on the said connecting pin 2; Said spring 5 is positioned at the gap 6 of said Connection Block 7 and contiguous block 3; Wherein said Connection Block 7 is installed on the tooth row body 9, and said Connection Block 7 is provided with adjustable alignment pin 4, and described back contacts with described alignment pin 4 when swinging by rule 6.

Seal back equipment is long-term in service, and chain 1 just produces the stretching phenomenon, because tooth row body 9 is connected with chain 1 through contiguous block 3; Therefore, when the tooth sheet 10 on the tooth row body 9 was held paper in the month, the position of its stop just can not be accurate; Therefore; When gold stamping or cross cutting, the position will produce deviation, and has influenced the precision of post-press finishing.When influencing the post-press finishing precision when chain 1 generation stretching phenomenon; As long as regulate alignment pin 4; Promptly turn alignment pin 4 through nut 11, the length that makes alignment pin 4 expose Connection Block 7 is able to change, when the back contacts with alignment pin 4 by rule 6 swings; The back just changes by the distance between rule 8 and the tooth row body 9, and so just scalable is brought the problem of post-press finishing low precision owing to chain 1 stretching phenomenon.Certainly, when turning alignment pin, be that the dependence experience is carried out with nut 11.When revealing 4, alignment pin goes out the length of Connection Block 7 when big slightly; The back is by after advising 8 swings and alignment pin 4 contacting; Owing in the gap 6 of Connection Block 7 and contiguous block 3, spring 5 is installed; These spring 5 meetings automatically tooth are arranged body 9 and the back regulated by the distance of advising between 6, arrive the station of appointment, device processes after supplying to print when holding paper in the month with the tooth sheet 10 on the assurance tooth row body 9.This structure of the utility model, very simple, and also easy to adjust, be specially adapted to print in the cross cutting machinery of back equipment.
