Abstract
The utility model relates to a needle rod transmission mechanism of hand sack sealers, which relates to a design invention of a needle bar driving mechanism. The utility model comprises a machine head shell 1 and a needle bar driving mechanism arranged in a machine head hollow cavity, wherein, the needle bar driving mechanism is composed of a rocker 2, a connection rod 3, a fixing component 4 which is fixed on a needle bar and a needle bar 5. The rocker is composed of a shaft sleeve and two flat bars which are vertically fixed on the shaft sleeve and are oppositely parallel, and the shaft sleeve is sheathed on a working shaft which is fixed on the machine head shell in a swing type. The end of one flat bar is communicated with a power mechanism, and the end of the other flat bar is movably hinged with one end of the connection rod 3 near a needle head of the needle bar. The connection rod 3 is movably hinged with a fixing component which is fixed on the needle bar corresponding to the end of the needle head which is opposite to the needle bar, [and] the working position of the needle bar of the machine head is ridged to the direction opposite to the needle head corresponding to the other side shell of the needle head to form a motion cavity of the needle bar. Designed according to the motif, the utility model has the advantages of light weight and low labor intensity, and in addition, the utility model can prevent electric shock and electric leakage.
Description
Technical field
The head transmission mechanism for needle bar of the utility model portable bag closer relates to the improvement invention of shank operating mechanism
Background technology
In existing technology, the head transmission mechanism for needle bar of portable bag closer is owing to the moving mutually pivotally attached link member of shank connecting element is and the relative nearer end of shank syringe needle distance, the link member other end is relative to far-end with shank syringe needle distance, this end is moving hinged mutually with the flat bar termination on the fork, side body protrudes downwards and forms the shank epitrochoidal chamber under the corresponding with it head, be convenient to normal operation uses for the distance that keeps head downside and portable bag closer bench board, need comparatively speaking closer body (head supports partly) is extended axially, because axis is to having longer distance, in order to keep its working strength, case material is generally selected metallic material for use, therefore cause closer heavier, labour intensity is big when portable, moreover metallic material easily gets an electric shock, there is potential safety hazard in situations such as electric leakage.
Summary of the invention
At the defective that prior art exists, the utility model aims to provide a kind of transmission mechanism for needle bar, thereby changes the material of its closer housing, reaches body and guides and supports light, as to reduce labour intensity and raising safety performance purpose.
The utility model is finished as follows: comprise head shell and be positioned at the transmission mechanism for needle bar of head cavity, this transmission mechanism for needle bar is by fork, link member, the connecting element and the shank that are fixed on the shank are formed, described fork is by axle sleeve and be vertically fixed on the axle sleeve and two flat bars of opposing parallel are formed, described axle sleeve is that the circumferential rotary type of axial restraint is sleeved on the working shaft, these working shaft two ends are fixed on the head shell, described two a flat bars wherein flat bar termination are communicated in actuating unit, described another flat bar termination is relative with link member moving hinged near shank syringe needle one end, described link member deviates from the termination of shank syringe needle relatively and moves hinged with the connecting element that is fixed on the shank, head shank working position relative shank syringe needle opposite side housing forms shank motion cavity to deviating from shank syringe needle direction protuberance;
The housing of portable bag closer is a plastic insulation material;
The inner chamber of the handle position housing of portable bag closer is provided with reinforced rib.
Press the head transmission mechanism for needle bar of the portable bag closer of the utility model theme, its housing adopts plastic insulation material, and not only complete machine is in light weight, volume is little, and energy-conservation energy and material is guided and supported conveniently, labour intensity is little during operation, is ensured at secure context especially, avoids electric shock, electric leakage incident to take place.

The specific embodiment
Accompanying drawing has disclosed the utility model principle, below in conjunction with accompanying drawing embodiment is described in further detail: comprise head shell (1), be provided with transmission mechanism for needle bar in the cavity of head shell, this transmission mechanism for needle bar is by fork (2), connecting element (4) and shank (5) that link member (3) is fixed on the shank are formed, described fork is by axle sleeve and be vertically fixed on the axle sleeve and two flat bars of opposing parallel are formed, fork (2), link member (3) and connecting element (4) are formed piston crank mechanism, described axle sleeve is that the circumferential rotary type of axial restraint is sleeved on the working shaft, working shaft is fixedly installed on the head shell, one flat bar termination of fork is communicated in actuating unit, action swings back and forth, another flat bar termination of described fork is relative with link member (3) moving hinged near shank syringe needle one end, described link member (3) deviates from the termination of shank syringe needle relatively and moves hinged with the connecting element (4) that is fixed on the shank, the opposite side housing of the relative syringe needle in head shank working position forms the motion space of shank and associated components to deviating from shank syringe needle direction protuberance.Former portable bag closer is because portable fuselage partial-length is bigger, thereby makes the package body need select for use metallic material to guarantee its working strength, but metal shell exists potential safety hazard seriously in use, is unfavorable for that product further applies.The utility model is because shank and associated components thereof form its motion space of piston crank mechanism moves up, can reduce the distance of package head comparatively speaking to the closer bench board, be that closer fuselage (head supports partly) distance can shorten some, then tackling the requirement of fuselage strength of material mutually reduces, so can select for use plastic insulation material as closer housing (particularly the fuselage handgrip is held the position), not only economize on resources, and the safety of portable bag closer is protected, in order to guarantee its fuselage intensity, the housing inboard can be provided with reinforced rib.
Claims (3)
1. the head transmission mechanism for needle bar of a portable bag closer, comprise head shell (1) and be positioned at the transmission mechanism for needle bar of head cavity, this transmission mechanism for needle bar is by fork (2), link member (3), the connecting element (4) and the shank (5) that are fixed on the shank are formed, described fork is by axle sleeve and be vertically fixed on the axle sleeve and two flat bars of opposing parallel are formed, described axle sleeve is that the circumferential rotary type of axial restraint is sleeved on the working shaft, these working shaft two ends are fixed on the head shell, described two a flat bars wherein flat bar termination are communicated in the closer engine installation, it is characterized in that: another flat bar termination is relative with link member (3) moving hinged near shank syringe needle one end, described link member (3) deviates from the termination of shank syringe needle relatively and moves hinged with the connecting element that is fixed on the shank, head shank working position relative shank syringe needle opposite side housing forms shank motion cavity to deviating from syringe needle direction protuberance.
