DETAILED DESCRIPTION

[0030] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0032] In the description of the utility model, it needs to explain, unless another explicit provision and limitation, term "installation", "link", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can be indirectly connected through intermediate medium, can be two elements inside the intercommunication. For ordinary skilled in the art, can understand the specific meaning of the above terms in the utility model according to specific circumstances.

[0033] As Figures 1-10 The utility model discloses a kind of needle plate board gap control devices of flat knitting machine, including needle bed body 1 and needle plate 2, the needle bed body is triangular, for installing needle plate 2 in inverted "V" line.

[0034] In the present scheme, needle plate 2 has two, after laying on needle bed body, the upper edge of two needle plates is close to each other and forms a needle plate board gap.

[0035] It needs to be explained that, in the process of weaving flat knitting, the gap "W" of the needle plate board gap is adjusted, the adjustment of the weaving density of woven fabric under the same pattern can be realized, so as to achieve the purpose of different presentation effect under the same knitting needle method.

[0036] And in order to achieve the above purpose, four blocks 3 are installed on needle bed body, and the four blocks are two groups, and are respectively installed on one slope of needle bed body. Specifically, two blocks are respectively installed on needle bed body and are pressed on both ends of needle plate, so as to exert a constraint on needle plate, so as to ensure that needle plate can only slide in the width direction of itself on needle bed body.

[0037] Meanwhile, two groups of output mechanisms 5 and two groups of control mechanisms 4 are also installed on needle bed body 1. Among them, the control mechanism is connected with needle plate 2, and the output mechanism is connected with the control mechanism, the control mechanism is driven to act through the output mechanism, and then the needle plate is driven to slide in the width direction, finally the purpose of adjusting the size of needle plate board gap formed by two needle plates is achieved.

[0038] It needs to be explained that, in the present scheme, control mechanism 4 includes a pull plate 41 and a push plate 42 arranged at the lower edge of needle bed body 1. Figure 6As shown, the needle plate is provided with a plurality of first limiting grooves 411 extending along the length direction of the needle bed body 1, and a plurality of first guide assemblies 45 are installed in the first limiting grooves. When the pull plate is subjected to a length direction pushing and pulling force, the pull plate is constrained by the first guide assemblies 45 fixedly installed on the needle bed body, and can only slide along the extension direction of the first limiting grooves 411. In addition, it should be noted that at least one control groove 412 is provided on the pull plate, which is an inclined groove. Specifically, the extension direction of the control groove forms an angle with the length extension line of the needle plate 2. At the same time, a plurality of second guide assemblies 46 are slidingly fitted in the control groove, and the second guide assemblies are fixedly installed on the push plate, and only need to be constrained in the width direction of the needle plate (constraining the push plate to slide in the width direction of the needle plate). When the pull plate slides transversely, the push plate slidingly fitted on the pull plate will be driven by the second guide assemblies 46 in the control groove to rise and fall in the width direction of the needle plate, thereby synchronously driving the needle plate 2 connected with the push plate to rise and fall.

[0039] It should be noted that on the basis of the above embodiment, the control mechanism 4 further comprises a pressing plate 48. The pressing plate serves to press the two ends of the pull plate that are not pressed by the push plate, so as to prevent the end of the pull plate from being raised during operation. Specifically, the pressing plate 48 has two pieces, which are smoothly fitted on the two ends of the pull plate. At the same time, at the position where the pressing plate is arranged, the pull plate is also provided with a first limiting groove, and a plurality of first guide assemblies pass through the pressing plate and the first limiting groove and are fixedly installed on the needle bed body 1, so as to ensure the stability of the pressing plate during transverse sliding of the pull plate.

[0040] It should be noted that in order to better constrain the movement direction of the push plate when pushing the needle plate, a second limiting groove 421 extending along the width direction of the needle plate is provided on the push plate 42. At the same time, a limiting nail shaft 44 is installed on the needle bed body, and the limiting nail shaft is slidingly inserted in the second limiting groove 421 to constrain the sliding direction of the push plate.

[0041] It should be noted that in the present scheme, the first guide assembly 45 and the second guide assembly 46 are both the same structure, which is a core shaft 451 and a bearing 452 rotatably mounted on the core shaft. It should be noted that in the present scheme, the first guide assembly and the second guide assembly are installed with a bearing on the core shaft, so that when the core shaft is installed on the corresponding structure, the outer wall of the bearing is in contact with the groove wall. In actual, no matter how smooth the groove wall is, there is friction between the groove wall and the bearing, so when the force acting on the bearing is unbalanced, the outer ring of the bearing can roll in the groove to avoid the situation that the groove wall and the bearing are in contact and friction for a long time, causing the bearing or the groove wall to wear seriously. Through this setting, the service life of the first guide assembly and the second guide assembly can be greatly prolonged.

[0042] It should also be noted that the push plate in the control mechanism 4 inevitably has a certain tolerance during production, which causes the push plate and the needle plate to be misaligned after being connected (mainly the push plate has a certain uneven height at both ends). At this time, workers need to calibrate the push plate to ensure that the lifting amplitude and direction of both ends remain synchronized when the push plate pushes the needle plate up and down. Therefore, a piece of adjusting plate 43 is fixedly connected to the push plate by bolts, and a third limiting groove 431 extending along the length direction of the needle plate is formed in the adjusting plate. At the same time, a group of eccentric adjusting assemblies 47 are installed on the needle bed body 1, which are located in the third limiting groove. When the push plate is uneven at both ends, the height of the push plate connected to one end of the push plate is raised by adjusting the center position of the eccentric adjusting assembly in the third limiting groove. Specifically, in the present scheme, the eccentric adjusting assembly 47 includes an eccentric shaft 471 installed on the needle bed body, which extends into the third limiting groove. At the same time, an eccentric shaft 452 is installed on the eccentric shaft, which is also eccentrically arranged in the third limiting groove. When the height of the adjusting plate needs to be adjusted, the eccentric shaft is rotated to adjust the deviation position of the shaft center of the bearing in the third limiting groove.

[0043] It should be noted that in the present scheme, the output mechanism 5 driving the control mechanism to move, specifically includes a motor 51 installed on the needle bed body 1, and a gear 52 coaxially installed on the output shaft of the motor. At the same time, a rack 53 is installed on the pull plate, which extends along the length direction of the needle plate, and the rack is engaged with the gear. When the motor drives the gear to rotate, the gear drives the rack to reciprocate along the length direction of the needle plate, thereby driving the pull plate to slide transversely, and finally driving the needle plate to lift.

[0044] Working Principle: When the needle plate gap between the two needle plates needs to be adjusted, the motor in the output mechanism rotates, driving the gear. As the gear rotates, the meshing rack undergoes varying lateral motions. This lateral movement of the rack causes the pull plate to move accordingly. During this movement, the control slot and the second guide assembly mounted on the push plate undergo relative displacement. The second guide assembly, driven by the control slot, then rises and falls. As the second guide assembly rises and falls, the push plate, fixed to it, rises and falls synchronously, pushing the needle plates connected to it up and down. This causes the gap between the two needle plates to change, allowing the gap between the needle plates to be adjusted.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
