The detailed description and technical content of the present invention are described as follows in conjunction with the drawings:

1 to 5, the present invention proposes a flat knitting machine cloth pressing device 40 that changes its position with the size of the mouth. The mouth 10 in the present invention is set by a flat knitting machine 100 in two needle beds 11, 12 The facing plurality of tines 16 are defined, and these tines 16 are respectively driven by the corners of the tines 132 to generate displacement, thereby changing the size of the mouth 10.

In addition, the flat knitting machine cloth pressing device 40 of the present invention is arranged in plural on the flat knitting machine structure 100, and each flat knitting machine cloth pressing device 40 is respectively arranged in one of the mountain angle systems 13 included Mount 137 on a mountain corner bearing. Each flat knitting machine cloth pressing device 40 includes a drive The movable member 41, a fixed seat 42 arranged on the horn bearing seat 137, a pair of the sliding seat 43 arranged corresponding to the fixed seat 42, and a pair of the fixed seat 42 which is combined with the fixed seat 42 and at the same time restricts the sliding seat 43 to only oppose the The limit block 44 on which the mountain horn bearing seat 137 slides, a cloth pressing piece support arm 45, and a cloth pressing piece 46 arranged on the cloth pressing piece supporting arm 45 and driven by the sliding seat 43.

Wherein, the driving member 41 is started by a displacement stroke 133 at the horn 132 of the tine piece. That is to say, the activation of the driving member 41 is based on whether the antenna ridge 132 performs the displacement stroke 133. Therefore, when the anterior chip horn 132 is displaced, the driving member 41 is displaced immediately.

Furthermore, the sliding block 43 not only corresponds to the fixed seat 42, but also makes an adjustment stroke 431 relative to the mountain angle bearing seat 137 when the driving member 41 is displaced. In addition, a guiding block 432 is provided on the sliding block 43.

In view of this, when the driving member 41 is activated, because the pushing portion 412 can only perform one-dimensional movement, once the pushing portion 412 is displaced, the sliding seat 43 needs to generate simultaneous displacement, and the displacement of the sliding seat 43 is that The adjustment stroke 431 is referred to herein. Furthermore, the sliding block 43 can also be a U-shaped structure, which is arranged on the mountain angle support 137 in a U-shaped manner during assembly, and the fixing seat 42 can be arranged in a recess in the aforementioned U-shaped structure. In addition, the sliding block 43 may have a first strip hole 436 in which the fixing seat 42 is provided. The first strip hole 436 is not the depression of the U-shaped structure as previously referred to herein, but corresponds to the depression. An opening is provided, and the size of the first strip-shaped hole 436 is set to at least the extent that the sliding block 43 can perform the adjustment stroke 431.

In addition, the height of the fixing base 42 can be further as high as the sliding block 43, so that the limiting block 44 can restrict the sliding block 43 more specifically. In addition, one end of the cloth pressing piece support arm 45 is fixed to the guide rod 30 of the yarn feeder, and the other end is provided with a mounting seat 451. The mounting seat 451 A channel 452 is formed. Specifically, the mounting seat 451 may be composed of a first component 453 and a second component 454 assembled with the first component and defining the passage 452 together. In addition, the cloth pressing sheet 46 includes a control section 461 connected to the guide block 432, a connecting section 462 extending from the control section 461 and passing through the passage 452, and a connecting section 462 extending from the connecting section 462 and facing one of them. The cloth pressing section 463 of the needle bed 11 (or 12). Wherein, the control section 461 forms a linkage relationship with the guide block 432, and the control section 461 drives the cloth pressing section 463 to shift when the sliding seat 43 makes the adjustment stroke to change the cloth pressing position. In one embodiment, the cloth pressing sheet 46 has a guide rod 464 disposed on the control section 461, and the guide block 432 is provided with a groove 437 for the guide rod 464 to be inserted. The groove 437 is in the form of At least in conformity with the guide rod 464, the groove 437 can be implemented in a rail type. In addition, the width of the connecting section 462 corresponds to the width of the passage 452, so that the connecting section 462 can slide in the passage 452, and the cloth pressing section 463 generates a working surface for pressing cloth through a significant size change.

Please refer to Figures 2 to 5 again, continuing, the time point when the flat knitting machine pressing device 40 changes the position of the pressing is when the mouth 10 changes, so the present invention makes the flat knitting machine pressing device 40 and the At the same time, the 132 angles of the Tianfang tablets moved simultaneously. Therefore, when the driving member 41 is activated when the horn 132 is controlled to produce displacement, the driving member 41 drives the sliding seat 43 to make the adjustment stroke 431, and then the guide block 432 moves due to the sliding seat 43 When a displacement occurs, the control section 461 is driven by the guide block 432 to cause the connecting section 462 to slide in the channel 452, thereby changing the position of the cloth pressing section 463 in the mouth 10.

Please refer to FIGS. 2 to 5 again. In one embodiment, the driving member 41 has a connecting portion 411 connected to the horn 132 of the antenna and a pushing portion 412 connected to the connecting portion 411. The driving member 41 has a driving stroke 413 for displacing the pushing portion 412 when the displacement stroke 133 is traveled at the angle 137 of the toothed piece. Moreover, in this embodiment, the driving member 41 may be integrated The forming or the assembling of plural components is completed. For example, the assembling part 411 and the pushing part 412 may be different components. In addition, the driving member 41 may have a push rod 414 provided on the pushing portion 412. On the other hand, the sliding block 43 has an oblique guide path 433 on one side of the sliding block 43 and into which the pushing part 412 is inserted. In addition, the sliding seat 43 has a first surface 434 facing the mountain corner bearing seat 137, and a second surface 435 facing the limiting block 44, and the inclined guide path 433 is disposed on the sliding The seat 43 is adjacent to the side of the driving member 41, and the oblique guide path 433 extends from the first surface 434 to the second surface 435 in a direction away from the horn 132. The oblique guide path 433 provides the push rod 414 disposed therein, and the width of the oblique guide path 433 can correspond to the push rod 414 so that the pushing portion 412 can specifically push the sliding seat 43.

6 and 7, in another embodiment, the driving member 41 is composed of a motor 415 and a gear 416 connected to the motor 415, and one side of the sliding seat 43 is provided with a gear 416 in contact with the gear 416. The rack 438. The motor 415 is connected to a control device (not shown in this figure), and the control device not only controls the motor 415, but also controls a displacement mechanism for driving the horn 132 of the antenna. When the control unit sends a working signal to the displacement mechanism, it will simultaneously send a start signal to the motor 415 to start the motor 415 to make the gear 416 rotate. When the gear 416 rotates, it will push the rack 438 to make The sliding block 43 runs the adjustment stroke 431.

2 to 5, in order to increase the structural stability of the flat knitting machine press device 40, in one embodiment, the limit block 44 has a first hook protruding toward the direction of the press sheet support arm 45 Portion 441, the cloth pressing piece support arm 45 has a second hook portion 455 disposed on the mounting seat 451 and protruding toward the limiting block 44 and assembled with the first hook portion 441. Further, the opening directions of the first hook portion 441 and the second hook portion 455 are opposite.

2 and 3, in one embodiment, the cloth pressing sheet 46 has a second strip hole 465 disposed on the connecting section 462, and the mounting seat 451 has at least one communicating channel 452 and providing a The mounting member 47 is provided corresponding to the second strip hole 465 to limit the mounting hole 456 of the cloth pressing piece 46. In this way, the cloth pressing piece 46 is prevented from being abnormally separated from the channel 452.
