Abstract

The utility model discloses a triangular guide block module for knitting loom, which comprises a mounting plate with an isosceles triangular hole; a first triangular guide block is arranged below the isosceles triangular hole on the mounting plate; a first guide groove, a second guide groove and a third guide groove are arranged on the first triangular guide block; a second triangular guide block is flexibly arranged into the isosceles triangular hole; an isosceles triangular boss is arranged on the second triangular guide block, which is smaller than isosceles triangular hole and positioned into the isosceles triangular hole; a first limiting groove and a second limiting groove are arranged on the second triangular guide block. The needle of knitting loom moves along the guide groove on the first triangular guide block and the limiting guide groove on the second triangular guide block; by changing the position of the first triangular guide block in the isosceles triangular hole, the needle of knitting loom can move along different tracks for controlling the stroke of needle.

Description

The knitting machine cam guide block module

[technical field]

The utility model relates to knitting machine, especially relates to a kind of knitting machine cam guide block module.

[background technology]

The head triangle of existing knitting machine is made up of a lot of modules, and each module is interactive, and very high to the position of triangle and the requirement of quality of fit each other, complex structure breaks down and maintenance difficult easily, the cost height.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of knitting machine cam guide block module, and is simple in structure, the reliability height, and cost is low.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of knitting machine cam guide block module is provided, described cam guide block module comprises that one has the fixed head of an isoceles triangle endoporus, on the described fixed head, first cam guide block is installed under the isoceles triangle endoporus, on described first cam guide block first guide groove is set, second guide groove, the 3rd guide groove, movable second cam guide block of installing in the described isoceles triangle endoporus, described second cam guide block has an isoceles triangle shape boss, described isosceles triangle boss is less than the isoceles triangle endoporus and be placed in the isoceles triangle endoporus, on described second cam guide block first stopper slot is set, second stopper slot.

Further improvement in the technical proposal is:

The fixedly connected drive plate of the isosceles triangle boss of described second cam guide block, erect on the drive plate drive rod and a positioning rod are arranged, one spring is installed on the backstay and is strained to isoceles triangle endoporus top-direction, drive rod flexibly connects a crank, one end of crank has a boss, the drive rod end comes to this boss Toru, and the other end of crank is connected in the clutch end of knitting machine.

The beneficial effects of the utility model are: the utility model comprises three triangles, and first cam guide block has three multidirectional guide grooves for what fix above first cam guide block; Two stopper slots are arranged on second cam guide block, and second cam guide block has three positions that are positioned at isoceles triangle endoporus summit along the activity of isoceles triangle endoporus.Drawing of knitting machine has two guide ledges on the pin, a boss is along the guide groove movement on first cam guide block, and another boss moves along the stopper slot on second cam guide block.The change of the second cam guide block position makes boss move along different tracks, thus the impulse stroke that pin is drawn in control.One crank that is connected in the clutch end of knitting machine is controlled the conversion between the position on three isoceles triangle endoporus summits of second cam guide block.Therefore this cam guide block modular structure is simple, and is low to the status requirement precision of cam guide block, the reliability height, and cost is low.

[specific embodiment]

See also Fig. 1 to Figure 17:

An isoceles triangle endoporus 2 is offered at fixed head 1 middle part, first guide groove 4 that boss forms, second guide groove 5 (among Fig. 2 shown in the curve), the 3rd guide groove 6 (among Fig. 2 shown in the curve) are arranged on first cam guide block 3, first stopper slot 8 that boss forms, second stopper slot 9 (among Fig. 4 shown in the curve) are arranged on second cam guide block 7, and the back side of second cam guide block 7 is provided with isosceles triangle boss 10.First cam guide block 3 is fixedly mounted under the isoceles triangle endoporus 2 in the fixed head 1, the isosceles triangle boss 10 of second cam guide block 7 is less than isoceles triangle endoporus 2, isosceles triangle boss 10 activities of second cam guide block 7 are contained in the isoceles triangle endoporus 2, and isosceles triangle boss 10 has three positions: be positioned at isoceles triangle endoporus 2 drift angles (shown in Figure 8), left comer (shown in Figure 9), right corner (shown in Figure 10).

Fig. 7 is the structure chart of knitting power traction pin, and knitting power traction needle set has boss 11, boss 12, and boss 11 moves along the stopper slot of second cam guide block 7, and boss 12 is along the guide groove movement of first cam guide block 3.When isosceles triangle boss 10 is in primary importance (isoceles triangle endoporus 2 drift angles), because first stopper slot 8 is spacing, boss 11 moves along first stopper slot 8, and boss 12 moves along first guide groove 4 of first cam guide block 3.When isosceles triangle boss 10 is in the second place (isoceles triangle endoporus 2 left comer), because second stopper slot 9 is spacing, boss 11 moves along second stopper slot 9, and boss 12 moves along the 2nd guide groove 5 of first cam guide block 3.When isosceles triangle boss 10 is in the 3rd position (isoceles triangle endoporus 2 right corner), because first stopper slot 9 is spacing, boss 11 moves along second stopper slot 9, and boss 12 moves along the 3rd guide groove 6 of first cam guide block 3.In other words, isosceles triangle boss 10 is in three positions, and knitting power traction pin just has three kinds of different tracks, sees Figure 17.

Isosceles triangle boss 10 fixedly connected drive plates 13, erect two drive rods 14 and backstay 15 on the drive plate 13, one spring (not shown) is installed on the backstay 15 and strains to isoceles triangle endoporus 2 top-direction, drive rod 14 flexibly connects a crank 16, one end of crank 16 has a projection 17, drive rod 14 ends come to this projection 17, and the other end of crank 16 is connected in the clutch end of knitting machine.Crank 16 rotates, and drives isosceles triangle boss 10 and changes between three positions, sees Figure 16.
