Description
Technical field
The present invention relates to a kind of buffer and its operational approach and in particular to a kind of in textile industry loom slow
Rush device and its operational approach, belong to textile industry field.
Background technology
With economic and scientific and technological development, original craft is weaved cotton cloth to be weaved cotton cloth by machine and is replaced, and improves production effect
Rate, the loom commonly used at present mostly has the form of shuttle, the transmission by shuttle and reciprocating motion to change parallel and regular arrangement
Warp be woven in together, shuttle body leans on the impact of hitting-shuttle plate back and forth to tell motion, the shuttle braking buffering that existing loom uses
Device great majority adopt tengential belt or apron, and this buffer unit consumes the remaining kinetic energy of shuttle, its impulsive force by colliding and rubbing
Greatly, leather block, picker stick consumption are more, and performance is unstable, need to often adjust, and buffering effect is not good, have a kind of inflated type at present
Oil pressure shuttle producing bumper, enters row buffering using hydropneumatic type pneumohydraulic spring, but this readily permeable, and elasticity is big, and shuttle positioning is inaccurate
Really, the buffer of existing loom is more single, and buffering effect difference is it is impossible to meet many demands, poor for applicability, researches and develops one
Planting to overcome the loom buffer of disadvantages described above to become those skilled in the art's technical problem urgently to be resolved hurrily.
Content of the invention
The technical problem to be solved is, the shortcoming overcoming prior art, provides a kind of combination type of loom
Buffer and its operational approach, this buffer is the form of combination, strong applicability, good buffer effect, and energy consumption is low, simple to operate,
Using reliable and stable so that buffer response speed controllability is strengthened, be conducive to the stable operation of buffer, reach guarantee and weave cotton cloth
Quality and efficiency.
In order to solve above technical problem, the present invention provides a kind of combined buffer of loom, including buffer case
Body and be arranged at piston in buffer case body, buffer housing includes the first housing and second housing of vertically symmetrical setting,
Piston includes the first piston stretching in first shell body and stretches into second piston in second shell body, wherein:
First housing and the second housing are rectangular structure and the sealing of one end open one end of hollow, and the first housing is by outer
Shell and the inner shell composition being set in inside the shell, inner shell is provided with least four through holes, and inner shell is connected with shell；Second housing close
Envelope one end has been bolted to connection spring, and spring is fixedly connected with the first flat board away from one end of the second housing, and first is flat
The centre of plate has a groove；
First piston in first shell body is made up of First piston bar and piston sheet, and piston sheet is bolted to connection
In First piston bar, piston sheet is made up of upper piston piece and lower piston piece from top to bottom, and upper piston piece and lower piston piece are all opened
There is circular hole；
Second piston in second shell body is made up of second piston bar and piston head, and piston head is to be fixedly connected by nut
The second flat board on second piston bar, the second flat board is adapted with the first flat board, the groove on spring one end first flat board with
Nut is adapted, and First piston bar is fixed together by a horizontally disposed connecting rod with second piston bar.
The technical scheme that the present invention limits further is:
In the combined buffer of aforementioned loom, also include the case lid being set in First piston bar, case lid with
First housing opening is adapted, case lid by the first housing seal, the first housing be provided with case lid reinforced it is ensured that
Sealing that operation is is it is ensured that fluid does not spill over it is ensured that buffering effect.
In the combined buffer of aforementioned loom, inner shell is provided with four through holes, and through hole is symmetrically distributed in inner shell lower end
Both sides and inner shell upper end both sides.
In the combined buffer of aforementioned loom, on upper piston piece and lower piston piece, circular hole is in staggered distribution, in the present invention
Piston sheet adopt biplate to form, the position that circular hole staggers can be adjusted, control well the response speed of tension force and buffer.
The present invention have also been devised a kind of operational approach of the combined buffer of loom, specifically includes following steps:
A. first buffer housing is totally separated with piston, into inner shell, then injects lubricating oil, then pass through to connect
First piston bar and second piston bar are stretched into corresponding first housing and the second housing by bar simultaneously；
B. the case lid in First piston bar is fixed on the first housing open at one end, and by the picker stick pair on loom
Place in the middle part of the connecting rod of this combined buffer accurate；
C. the upper piston piece on rotary-piston piece and lower piston piece are so that the circular hole on upper piston piece and lower piston piece staggers
Distribution；
D., when picker stick and connecting rod collide, connecting rod promotes First piston bar and second piston bar to move simultaneously,
First piston bar extrudes the lubricating oil in inner shell, and lubricating oil is gone out from the through hole overflow of inner shell both sides due to pressure, lives with first
Stopper rod close to inner shell bottom, enter lubricating oil in the shell through hole from inner shell upper end and flow to inner shell from newly, in piston sheet by overflow
Cushioning effect is received in motor process；
Connecting rod promotes second piston bar to move, and second piston bar gradually extrudes the spring in second shell body, and spring is to the
Two piston rods carry out cushioning effect, and First piston bar and second piston bar are made by picker stick is entered with row buffering by connecting rod
With.
The technical scheme that the present invention limits further is:
In the operational approach of the combined buffer of aforementioned loom, in step c, buffer speed as needed is adjusting
The position that upper piston piece is staggered with circular hole on lower piston piece, circular hole staggered positions are bigger, and buffer speed is slower；The position that circular hole staggers
Put less, buffer speed is faster
The invention has the beneficial effects as follows:
By the way of combination, fluid pressure type and elastic force type are combined in the present invention, it is to avoid when they are used alone
The shortcoming existing, the mode of combination can make up the shortcoming of other side so that buffering effect more preferably, improves the adjustability of buffering；
The first housing in the present invention is made up of inner shell and shell, and has through hole on inner shell, and lubricating oil is in first piston
Because pressure overflows to shell in the upper end of inner shell when mobile, then overflow to the lower end of inner shell again, it is right to have circulated successively
First piston carries out cushioning effect, meanwhile, upper piston piece on piston sheet and lower piston piece has circular hole, according to practical situation
The position that upper piston piece and lower piston piece stagger can be adjusted, to accelerate the speed buffering, buffering effect is better, buffering adjustable
Property is strong；
In second shell body in the present invention, the first flat board on row buffering, and spring and the are entered by spring to second piston
Two flat boards are adapted, and nut is adapted with the groove on the first flat board, stress good it is ensured that buffering effect, will not be in work process
Middle generation landing phenomenon, second piston will not surprisingly and the first flat board stagger it is ensured that the normal operation that works；
The mode of combination, in the return path of back and forth movement, spring can drive the due to its elastic force in return path
First piston return movement in one housing, reduce energy consumption, Equilibrium energy consume the power it is not necessary to extra,
Reduce cost.
