Description
Technical field
The present invention relates to a kind of transmission balance mechanism of needling machine, the transmission balance mechanism of needling machine of particularly a kind of single connecting rod of single shaft transmission, single needle beam, single needle plate belongs to field of non-weaving textile machinery technology.
Background technology
In on-woven machinery, the structure of the transmission mechanism of the movable needle beam of the needing machine of single shaft transmission is to be made of the main shaft that is equipped with equilibrate counterweight, connecting rod, push rod, movable needle beam, needle plate, equilibrate counterweight is fixed on the main shaft, the main shaft hub setting is on frame, one end of main shaft sets firmly belt pulley, make main axis rotation by means of belt by belt pulley by power, the other end of main shaft links the upper end of connecting rod, and the lower end of connecting rod links with the upper end that is located at the push rod on the ram seat, the lower end of push rod and movable needle beam are fixed, and needle plate is fixed on the movable needle beam.During main axis rotation, drive and the eccentric upper and lower motion of connecting rod that links, and then drive the upper and lower motion of push rod, make push rod drive activity needle beam do to carry out acupuncture by the thorn on it at the nonwoven fabric (fabric) below the needle plate of passing through in the process of upper and lower motion.In whole transmission process, the eccentric balance of main shaft is to remedy by the balance that is configured on the main shaft, that is to say that the eccentric weight that eccentric block, connecting rod, push rod, movable needle beam, needle plate constitute solves equilibrium problem by adding balance.Yet, in the production process of the nonwoven fabric product of reality, because different different pricker number and rotating speed and the traverses of arts demand, thereby make eccentric weight and impulsive force produce respective change, weight difference is bigger, and uneven impulsive force is just bigger.The for example needing machine of the single shaft transmission below 600n/ divides for low velocity, as if can not produce imbalance problem, but needing machine for high-speed for example 800-1500n/ branch, because of the rotating speed of main shaft very high, the upper and lower impulsive force of activity rigid unitary is just big, the imbalance problem of main shaft is very outstanding, causes that needing machine shakes, the teeter amplitude is big, can't operate as normal.Because, under static state, eccentric block is made circular motion and is driven the counterweight weight that is made of connecting rod, push rod, movable needle beam, needle plate etc. and make moment that upper and lower motion produces and equal balance and make the moment that circular motion produces, so system is in poised state; Under dynamically, although system has been in the static balance state, but because aforesaid balance is being made the same centrifugal force that also produced of trimming moment that circular motion produces, this centrifugal force is directly proportional with rotating speed, rotating speed is higher, centrifugal force is just bigger, causes the needing machine teeter, thereby produces restriction for the raising of machine performance and speed.Just because of above-mentioned reason, cause the speed of the needing machine of present single spindle can't go beyond the 800n/ branch, thereby exert an influence for properties of product and working (machining) efficiency.
The applicant also retrieves, and has detected two pieces of Chinese patent documents, i.e. ZL2004200-78873.6 and ZL200420078875.5, and title is respectively the transmission mechanism of movable needle beam, the spindle eccentricity bascule in the movable needle beam transmission mechanism.The disclosed technical scheme of above-mentioned documents is at tease needle machine, with regard to structure, the two main shafts of system, double link, two push rod, Dual Action needle beam, crosspointer plate structure, pair of links (double link) goes up eccentric fixing at a pair of main shaft (two main shaft), eccentric force can be repealed by implication, and the weight of formation such as double link, Dual Action needle beam, crosspointer plate can lean on the pressure of regulating spring and hydro-cushion cylinder to come balance.Yet for the needing machine of the single main shaft that widely uses at present, single connecting rod, single movable needle beam, single needle plate, the structure of documents just can't be suitable for.
Theoretically, for just also not being restricted at present at the rotating speed of the general acupuncture machine of simple, the cheap relatively single spindle of in commission various lots of structure, yet owing to lack technical guarantee, the highest degree of also only dividing of the rotating speed of this needing machine at 600-800n/.Because, when rotating speed smaller or equal to the 600n/ timesharing, the centrifugal force that the configuration balance weight produces can offset with the machine deadweight, makes acupuncture function operate as normal; And divide greater than 600n/ and smaller or equal to the 800n/ timesharing when rotating speed, though can operate as normal, existing significantly vibration exerts an influence to the quality of product; When greater than the 800n/ timesharing, serious vibration, machine can't operate as normal.
At present, no matter be the needing machine production firm of single spindle, still using the user of the needing machine of single spindle, all urgent wish to have have gratifying operating rate a kind of tease needle machine that is resembled two spindle, therefore, how to solve the problem that the equilibrium problem of the needing machine of single spindle has become industry to pay close attention to.
