Abstract
The utility model discloses a driving device of an electronic jacquard machine. The driving device of the electronic jacquard machine comprises a main shaft which is horizontally placed on a left wall board and a right wall board, wherein the shaft body of each end of the main shaft is respectively provided with two driving chain wheels, and the two driving chain wheels are respectively in transmission connection with two driven chain wheels on the wall boards through chains; and the driving device of the electronic jacquard machine is characterized in that the two driving chain wheels, the chains and the two driven chain wheels are positioned at the outer sides of the wall boards. According to the driving device of the electronic jacquard machine, disclosed by the utility model, after the two driving chain wheels at one end of the main shaft, the chains and the two driven chain wheels are arranged at the outer sides of the wall boards, the phenomena of lengthening and fracturing which frequently happen due to overlong chain and overlarge load can be effectively avoided, the space between the left wall board and the right wall board cannot be occupied, the improvement is simple, and the effect is obvious.
Description
[technical field]
The utility model relates to a kind of electronic jacquard machine transmission device.
[background technology]
At present, as the chain device that electronic jacquard machine generally uses, its structure mainly comprises a level to the main shaft that is shelved on the left and right sidesing wall plate, these main shaft two ends through drive sprocket, chain respectively with left and right sidesing wall plate on two driven sprockets be in transmission connection.Every driven sprocket be provided with can one rise and one drop campaign two connecting rods, the lower end of two connecting rods then respectively with corresponding girff, griffe to be cascaded.During operation, this main shaft, carries corresponding girff and goes up and down with four liter of four mode of falling through eight connecting rods on the chain drive machine under external force drives, and griffing on girff controlled solenoid movement, thereby realizes the weaving purpose.Because the transmission device of this structure exists chain load big, the phenomenon of elongation even fracture appears in regular meeting during chain.Be head it off, the applicant once proposed a kind of improvement project, and had proposed patent application with " electronic jacquard machine transmission device " to Patent Office of State Intellectual Property Office.This application main points are: establish two drive sprockets respectively at each end of said main shaft; And two drive sprockets are positioned at the inside and outside both sides of left wallboard or right wallboard; Be complementary therewith, be arranged on the inside and outside both sides that two driven sprockets on left wallboard or the right wallboard also are positioned at left wallboard or right wallboard; The drive sprocket of homonymy is connected by chain drive with driven sprocket.After the improvement, be connected with two driven sprockets respectively, therefore, can effectively avoid, load excessive phenomenon that elongation even fracture often occur long, in the normal service life that helps guaranteeing jacquard, reduce maintenance rate because of chain with two chains.But; Structure after the improvement is through practice after a while; Find also to exist following not enough: because corresponding drive sprocket and driven sprocket branch are located at the inside and outside both sides of wallboard, and the parts between two blocks of wallboards are a lot, itself just seem and very crowd; Thereby be installed in wallboard inboard drive sprocket and driven sprocket and can tie up the space, influence the installation of some parts.
[summary of the invention]
For overcoming above-mentioned defective, the utility model aims to provide a kind of electronic jacquard machine transmission device, and this device can solve not only that chain be difficult for to elongate even the problem of fracture, and has and do not tie up the space, and influences the advantage that some parts are installed.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: the structure of this electronic jacquard machine transmission device; Comprise that a level is to the main shaft that is shelved on the left and right sidesing wall plate; All be provided with two drive sprockets on the axle body of this each end of main shaft, described two drive sprockets two driven sprockets on chain and wallboard respectively are in transmission connection, and it is characterized in that: said two drive sprockets, chain and two driven sprockets all are positioned at the outside of said wallboard.
As preferably, said main shaft is arranged on the symmetrical center line of two driven sprockets.
Beneficial effect: the utility model all is arranged on two drive sprockets of main shaft one end, chain and two driven sprockets the outer rear flank of wallboard; Not only can effectively avoid, load excessive phenomenon that elongation even fracture often occur long equally, but also can not tie up the space between the left and right sidesing wall plate because of chain.Improvement is simple, effect is obvious.
, through embodiment the utility model is further described below in conjunction with accompanying drawing.
[description of drawings]
Fig. 1 is the schematic perspective view of an embodiment right-hand member of the utility model partial structurtes, mainly shows the transmission structures on the right wallboard lateral wall of jacquard among the figure.
Fig. 2 is that A among Fig. 1 is to view.
Among the figure: frame 1, girff 2, expansion tightening wheel 3, connecting rod 4, flange 5, flange 51, drive sprocket 6, drive sprocket 7, chain 8, driven sprocket 9, driven sprocket 91, connecting rod 10, expansion tightening wheel 11, expansion tightening wheel 12 griffes 13, right wallboard 14, main shaft 15, bearing block 151.
[specific embodiment]
Referring to Fig. 1, and combine Fig. 2.Frame 1 two symmetry is installed wallboard, and right wallboard 14 is positioned at the right-hand member of frame 1.The two ends of main shaft 15 are shelved on the bearing block 151 of left wallboard and right wallboard 14, by the external force driven rotary, and are arranged on the symmetrical center line of driven sprocket 9, driven sprocket 91, so that the installation of two chains 8,81.Main shaft 15 stretches out drive sprocket 6 and drive sprocket 7 is set on the axle body in right wallboard 14 outsides, and drive sprocket 6 and movable sprocket 7 be respectively through chain 8 and 81, and descends the auxiliary of expansion tightening wheel 3,11 and 12, is in transmission connection with driven sprocket 9, driven sprocket 91.
During operation; Main shaft 15 is through two drive sprockets 6 and 7, chain 8 and 81, and and down auxiliary in expansion tightening wheel 3,11 and 12, driven in synchronism driven sprocket 9 and 91 rotates; Thereby the connecting rod 4 and 10 that makes homonymy drives girffs 2, griffe 13 to do elevating movement, the action of control electromagnetic valve.
Claims (2)
