Abstract

The utility model relates to a paper sheet binding machine, which comprises a conversion of motion mechanism, a paper holding mechanism, a hook-thread mechanism, etc. which are the same as the mechanisms in a domestic sewing machine. The utility model is characterized in that a paper feeding shaft driven by a rotary main shaft through a transmission body rotates at constant speed, feeding teeth for driving the motion of the paper sheets and a cam kinematic pair for driving the swing motion along the feed direction of a swing bar with a thread hook are fixed on the feeding shaft, and presser feet rollers are arranged on presser feet pieces. The binding machine can gain the effect of binding in a suitable needle distance and can be convenient to disassemble, so the utility model can bind various paper pieces conveniently and particularly can be used for binding paper pieces which need to be disassembled, such as the examination paper whose volume header need to be sealed. The utility model has the advantages of compact structure, small size, convenient carrying and easy fabrication.

Description

Table thread-bound paper sheet binding machine

The utility model relates to a kind of binding papers equipment.

Gong Ying small-sized traditional thread binding paper binding machine mostly only plays punching functions in the market, and by artificial threading binding, not only process is loaded down with trivial details then, and pitch-row is excessive, only establishes the 2-3 hole usually, influences bookbinding quality; Also have and use high-power sewing machine to bind paper, though its speed is very fast,, presser feet overstocked owing to its stitch contacts reasons such as tension with paper, be easy to make the base stock breakage; On the other hand in the binding process upper thread and bottom line crossed loops around, in case binding finish, the dismounting relatively the difficulty, to the binding of some specific use, for example, the sealing examination paper binding, both required closeer stitch, be beneficial to maintain secrecy; Require again after reading, can break seal easily, step on branch after the dismounting one by one, just should not use this method for stitching.

The purpose of this utility model is to provide a kind of binding, desk-top traditional thread binding paper assembling machine for convenience detach of making things convenient for, and the stitch distance is suitable, the strong and harmless paper of penetration power, thus satisfy the needs of binding papers in the multiple industry.

The purpose of this utility model is realized by following mode.

Assembling machine described in the utility model, the rotational transform with main shaft that it includes in the identical domestic sewing machine is switching mechanism, feed mechanism, feeding pressure mechanism, string-hooking mechanism, the casing of straight reciprocating motion about shank and the eedle and has the needle plate that holds pin hole, casing is provided with the mandrel of placing the line shuttle, it is characterized in that;

1. described rotating spindle drives feed spool through travelling gear and makes constant speed and rotate, and is installed with the feeding tooth on feed spool, and its position is in the left and right sides that needle plate holds pin hole, and its feeding tooth whenever rotates a week with feed spool, promptly drives the paper certain distance of advancing.

2. also be set with a disc cam on the described feed spool, its position below the eedle that holds in the middle of the pin hole, this disc cam and be provided with driven fork that line colludes and constitute the cam oscillating motion and pay, fork is hinged on the casing, line colludes along feed direction and swings.During work, line catches on the little wire loop under the eedle throwing, because of the drive paper of feeding tooth travels forward, wire loop is enlarged, because the effect of fork, line colludes is being with big wire loop still to rest on the eedle below, when eedle gets off for the second time line is penetrated in the previous wire loop, thereby form the binding mode that wire loop overlaps wire loop on the paper bottom surface.

In order to obtain the suitable platen effect of tightness, thereby obtain the needle gage of suitable size, can on the pressure foot in feeding pressure mechanism rotating roller be set, the periphery of this roller is provided with the straight burr groove, the roller periphery contacts with paper and rolls on paper in paper is seen off process, and the presser feet sheet does not contact with paper.

Power resources of the present utility model can be with manually shaking handle, also can use a micro-machine to drive main shaft rotates, travelling gear between described main shaft and the driven shaft can be replaced by the sprocket wheel chain, perhaps also can use toothed belt wheel and synchronizing jugged belt to replace.

Accompanying drawing below by embodiment is further described.

Fig. 1 is a kind of embodiment structural representation.

Fig. 2 is the left view of Fig. 1.

In Fig. 1, be the power of main shaft (2) manually to shake handle (1), through crank (3), connecting rod (4) makes machine bar (5) drive eedle (7) and makes rectilinear motion up and down reciprocatingly, and (6) are the eedle clamp mechanism, and (8) are needle plate, and (9) are casing; On the other hand, the main shaft that rotates is by gear (19), idler gear (18) and driven gear (17) make feed spool (16) make constant speed and rotate, and (10) are the appearance pin holes on the needle plate, (11) and (15) be left and right sides feeding tooth, (12) for having the fork that line colludes, (13) for being fixed on the fork hinge on the casing, (14) are for being packed in the disc cam on the feed spool, this cam face is arc, and promptly its side face comprises the face of cylinder and plane two parts.

In Fig. 2, (20) be presser bar, (21) be the presser feet spring, on presser feet sheet (22), be provided with two rotating rollers (23), (24) be the fork control spring, (25) be flange on the fork (12), because this flange of elastic force effect is close on the cam periphery, rotation along with cam, have the fork that line colludes and swing around hinge, when paper stock travelled forward, line colluded the wire loop that catches on is enlarged, when eedle gets off for the second time line is penetrated in last wire loop, (26) are line shuttle axle installation site.Among the figure, the dotted line fork is its movement locus schematic diagram.

Use the binder of present embodiment, available No. 18 use in sewing machine pins are as this eedle, and the cured line of selling with market of terylene is a cord, are power when using artificial hand, can be easily to 60 writing paper (60g/m ²) bind, needle gage can be controlled between the 5-15mm, sends to make that the end of a thread is fixing can to obtain firm bookbinding effect after the end, cuts off place's wire loop with scissors when dismounting, light pull wire head then all wire loops come off automatically, very convenient.

This assembling machine not only can be used for binding archives, various bills etc., as a kind of binder easily in the office, and owing to can dismantle easily after its bookbinding, stitch density is suitable, needing can be used for the paper bookbinding of sealing volume head, laborsaving saving time, improve bookbinding speed greatly, also can guarantee to roll up the sealing effectiveness of head preferably.

Compare with existing binder, the utlity model has compact conformation, volume is urinated in carrying, and makes the advantages such as simple cost is low.
