Summary of the invention
Technical problem to be solved by this invention is to provide a kind of knitting machine cam guide block, and it is simple in structure, the reliability height, and cost is low.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of knitting machine cam guide block comprises a fixed head, is located at first cam guide block and delta panel on the fixed head with being arranged above and below.Described first cam guide block can protrude out and sagging being installed on the fixed head perpendicular to fixed head; Described delta panel is provided with second guide groove and chute, is provided with second cam guide block that can protrude out and sink in second guide groove, is provided with the slide block that can horizontally slip in the chute, and slide block is provided with the 3rd guide groove; Described first cam guide block and the second cam guide block interlock constitute a seesaw type interlinked mechanism, when first cam guide block protrudes out to a high position, and second cam guide block low level to second guide groove that sink then; And when first slide block sank to low level, then second slide block protruded out to the high position in second guide groove.
Preferably, described seesaw type interlinked mechanism comprises a connecting rod, and the two ends of connecting rod connect described first cam guide block, second cam guide block respectively, and the connecting rod middle part is located on the strong point, first end of connecting rod also is connected with a spring, and the below of second end also is provided with an electromagnet.
Preferably, described slide block inboard links to each other with a drive block, and described drive block also is connected in the clutch end of knitting machine.
The invention has the beneficial effects as follows: the present invention is by constituting the protrusion of two triangle guide blocks or sagging the cooperatively interacting of seesaw type transmission mechanism, and the cooperation of slide block is slided, can constitute the different needle passageway that draws, and can obtain the multiple different pin motion track that draws, thereby the impulse stroke that pin is drawn in control; And this cam guide block is simple in structure, and position accuracy demand is low, the reliability height, and cost is low.
The specific embodiment
See also shown in Figure 1ly, the invention provides a kind of knitting machine cam guide block, comprise a fixed head 1, be located at first cam guide block 2 and a delta panel 3 on the fixed head 1 with being arranged above and below.
Wherein, described first cam guide block 2 can protrude out out and the withdrawal of can sinking again perpendicular to fixed head 1 ground.
Described delta panel 3 is provided with second guide groove 30 and a chute 31, be provided with second cam guide block 32 that can protrude out and sink in second guide groove 30, be provided with a slide block that can horizontally slip 33 in the chute 31, described slide block 33 is provided with the 3rd guide groove 34, described slide block 33 inboards link to each other with a drive block (scheming not shown), described drive block is connected in the clutch end of knitting machine, horizontally slips in chute 31 to drive slide block 33.
As shown in Figure 3, draw the structure chart of pin 4 for knitting machine is used, it has two guiding blocks, 40,42, two guiding blocks 40,42 can limit the orbiting motion of coming out along first cam guide block 2, second cam guide block 32 respectively.
First cam guide block 2 and second cam guide block, 32 interlocks constitute a seesaw type interlinked mechanism, described seesaw type interlinked mechanism can be taked following a kind of frame mode: connect described first cam guide block 2 and second cam guide block 32 by a connecting rod (scheming not shown), and the connecting rod middle part is located on the strong point, first end of connecting rod is connected with a spring, and second end below is provided with electromagnet, when electromagnet energising produces electromagnetic attraction second end of connecting rod is adsorbed, and the cam guide block of this end is sunk; The cam guide block of connecting rod first end then protrudes out out, on the contrary, when the electromagnet outage, is then retracted by first end of spring with connecting rod, and the cam guide block of this end is sunk, and correspondingly, the cam guide block of connecting rod second end then protrudes out out.
As Fig. 4 and shown in Figure 5, when first cam guide block 2 protrudes out to a high position outwardly, second slide block, 32 sagging low levels to second guide groove 30, at this moment, the guiding block 40 that draws pin 4 upper ends moves along first track 51 that first cam guide block, 2 top edges limit out, and second track 52 that last cell wall limited that the guiding block 42 of lower end is then driven along second guide groove 30 moves.In addition, slide block 33 is according to the direction of motion of drawing pin 4, and slide into a certain side in the chute 31, limit one the 3rd track 53 by the 3rd guide groove 34 equally, with the guiding block 42 that draws guid needle along moving in the 3rd track 53, at this moment, drawing one the 4th track 54 that 40 of the guiding blocks of pin 4 upper ends are driven along first cam guide block, 2 belows moves.As shown in Figure 4, drawing pin 4 is towards right side motion, 33 right sides that slide into chute 31 of slide block; And as shown in Figure 5, when drawing pin 4 and moving towards the left side, 33 left sides that slide into chute 31 of slide block.As for the guiding block the 40, the 42nd that draws pin 4, move along first track 51 and second track 52, still move along the 4th track 54 and the 3rd track 53, then be to control by a redirect mechanism that cooperates with cam guide block, owing to be equipped with similar redirect mechanism on the existing knitting machine, and redirect mechanism is not an innovative point of the present invention, seldom give unnecessary details at this, when redirect mechanism was configured to not redirect, the guiding block 40,42 that draws pin 4 moved along first track 51, second track 52 respectively; And when redirect mechanism was configured to redirect, the guiding block 40,42 that then draws pin 4 moved along the 4th track 54, the 3rd track 53 respectively.
As shown in Figure 6, when first slide block 2 sink to low level in fixed head 1,32 of second slide blocks outwards protrude out to the high position in second guide groove 30, then form one the 5th track 55 between the following cell wall by second slide block 32 and second guide groove 30, the guiding block 42 that draws pin 4 lower ends promptly moves along the 5th track 55, drives the guiding block 40 that draws pin 4 upper ends simultaneously and moves along one the 6th track 56.At this moment, slide block 33 and the 3rd guide groove 34 need not draw guid needle 4, and therefore, slide block 33 can be arranged in the optional position of chute 31, and for example: left side, right side and central authorities, as shown in Figure 6, slide block 33 is positioned at the central authorities of chute 31.
The present invention is by constituting first cam guide block 2, the protrusion of second cam guide block 32 or sagging the cooperatively interacting of seesaw type transmission mechanism, and the cooperation of slide block is slided, can constitute the different pin limit channels of drawing, and can obtain the multiple different pin motion track that draws, thereby the impulse stroke that pin is drawn in control; And this cam guide block is simple in structure, and position accuracy demand is low, the reliability height, and cost is low.
