Abstract

The utility model relates to a knitting density regulating device for a flat knitting machine. A fork-shaped density shifting fork 3 is positioned under an original flat knitting machine head body C, wherein the fork end of the shifting fork is clamped on a density triangle screw rod B. A density shifting fork handle 1 penetrates through the machine head body and is fixed on a handle end of the density shifting fork 3 by nuts 5, and the shifting fork handle is positioned on the machine head body through a check ring 2. The device can propel the density triangle screw rod through the rotation of the density shifting fork so as to regulate a density triangle, and thus, operating force is reduced by using the lever principle. Because of the density shifting fork handle on a panel of the machine head, density regulation and locking positioning are independently separated. The utility model has the advantages of easier and more flexible operation and higher production efficiency.

Description

Flat machine knitting density adjusting device

Affiliated technical field

The utility model relates to the adjusting device of flat machine knitting density.

Background technology

In the prior art, the adjusting of flat machine knitting density mainly is to realize that by the control of density triangle concrete operations are: directly promote density triangular screw rod upper end and regulate.Because will overcome the pulling force of extension spring, and the position of operation application point on mechanics is undesirable, used operating physical force is big in actual motion, density triangular block easily push away motionless; Simultaneously, locate these two actions and need carry out together, make and adjust inaccurately, inconvenient, usually need adjust, greatly reduce production efficiency by other instrument owing to regulate density and locking wing nut.

Summary of the invention

Action required power was big when the utility model mainly solved in the prior art Auto-regulating System of Density of Heavy Medium, adjusted problems such as inaccurate, inconvenience.

For solving the problems of the technologies described above, the technical scheme that the utility model flat machine knitting density governor motion is provided is: connect a density regulating apparatus on original flat machine, this device mainly is made up of density shift fork, shift fork handle, back-up ring and nut, described density shift fork places under the handpiece body of flat machine, its fork is stuck on the density triangular screw rod, described shift fork handle passes handpiece body and is fixed on the pommel of density shift fork by nut, and the shift fork handle is positioned on the handpiece body by a back-up ring.

Thereby this device promotes the density triangular screw rod by the rotation of density shift fork, density triangular is regulated, utilize bar thick stick principle, operating physical force is reduced greatly, because density shift fork handle is on the panel of head, make and regulate density and two actions of locking positioning are separately independent, operate easier, flexible, the production efficiency raising.

Description of drawings

Fig. 1 is the structural representation of the utility model flat machine knitting density adjusting device.

Fig. 2 is the motion schematic diagram of this device.

Dotted line partly is the parts of original flat machine among the figure, A-wing nut, B-density triangular screw rod, C-handpiece body, D-pressing baffle plate, E-pressing guide block, F-triangle support plate gathering sill, G-density triangular; 1-shift fork handle, 2-back-up ring, 3-density shift fork, 4-packing ring, 5-nut.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment

As shown in Figure 1, the density shift fork (3) of a fork-shaped is positioned under the handpiece body (C) of original flat machine, and its fork is stuck on the density triangular screw rod; Go up to bore a through hole at handpiece body (C), density shift fork handle (1) passes this through hole and is fixed on the pommel of density shift fork (3) by nut (5), and the shift fork handle is positioned on the handpiece body by a back-up ring (2).Between nut and density shift fork handle, also be provided with packing ring (4).Referring to Fig. 2, rotating density shift fork handle (1) drives, the density shift fork (3) of Lian Jieing rotates around fulcrum 0 with it, is subjected to the active force of density shift fork, and density triangular screw rod (B) and joining density triangular (G) thereof are done as shown in Figure 2 rectilinear motion along support plate gathering sill (F).Density triangular screw rod (B) connects as one with density triangular (G) by pressing baffle plate (D), pressing guide block (E), the pressing guide block is because be set in the triangle support plate gathering sill (F), can only move along gathering sill, therefore, promote the triangle screw rod and just can drive the density triangular motion, reach the upper-lower position of regulating density triangular, thus the knitting density of control straight-bar machines.

The mode that traditional flat machine is regulated density triangular (G) is at first to unclamp wing nut (A), promotes density triangular screw rod (B), regulates density triangular behind suitable position, screws wing nut and fixes.Because the operation application point is on the top of density triangular screw rod, the position on its mechanics is undesirable, causes in the practical application operating physical force very big, density triangular block easily push away motionless.And active force of the present utility model is the middle part that acts on density triangular screw rod (B), and the rotating torque that is produced reduces operating physical force much smaller than traditional flat machine greatly.This mechanism is owing to regulate density (stirring the density triangular screw rod) and independently separate with two actions in locking wing nut location simultaneously, makes more convenient to operately, can finely tune knitting density easily, operates easier, flexible.

Claims (2)

1, a kind of flat machine knitting density adjusting device, it is characterized in that: on original flat machine, connect a density regulating apparatus, this device mainly is made up of density shift fork, shift fork handle, back-up ring and nut, described density shift fork (3) places under the handpiece body (C) of flat machine, its fork is stuck on the density triangular screw rod (B), described shift fork handle (1) passes handpiece body and is fixed on the pommel of density shift fork by nut (5), and the shift fork handle is positioned on the handpiece body by a back-up ring (2).
