Description
Technical Field
[0001] The utility model relates to the technical field of computer knitting, in particular to an adjustable triangle seat and a circular loom. Background Art
[0002] In the conventional design concept of circular knitting machines, the movement trajectory of all knitting needles needs to have an adjustable translation range according to the different requirements of fabric structure; and the movement trajectory of the knitting needle is controlled by the triangular curve groove on the cam. The cam itself is fixed on the slider, and the specific position of the cam is controlled by the up and down movement of the slider controlled by the cam seat, thereby adjusting the movement trajectory of the knitting needle.
[0003] At present, the main way to adjust the slider of related equipment in the industry at home and abroad is the screw bevel adjustment scheme: it consists of a slider with a 45-degree bevel and a reset spring to reset the slider, a bolt with a 90-degree taper on the end face, and an adjustment button with an indicator line engraved on the surface; the bolt contacts the 45-degree bevel surface of the slider, and the bolt is driven to rotate synchronously through the rotation of the adjustment button, and at the same time, the bolt moves back and forth. The 90-degree taper surface at the front end of the bolt and the 45-degree bevel surface of the slider rub against each other, thereby realizing the up and down movement of the slider. Although this scheme can play a role in adjustment, due to design or processing accuracy problems, there may be a deviation between the zero-position scale line in the indicator line and the zero position on the base, which will lead to errors in the adjustment accuracy and affect the adjustment accuracy.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; the technical features designed in different implementation modes of the utility model described below can be combined with each other as long as they do not conflict with each other; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0031] In the description of the present utility model, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof all mean "at least including".
[0032] In order to fully understand the improvements of the present invention, the adjustment process is first described in detail:
[0033] There is a "zero position" (a mark on the base) on the base. When the cam base is used for the first time, all the sliders on the cam base are in the initial position. Later, the up and down positions of the sliders can be adjusted according to the different requirements of the fabric structure to meet the requirements of different knitting needle trajectories. When the slider is in the initial position, the "zero position scale line" of the position indicating line on the position indicating mechanism is required to be aligned with the zero position on the base to ensure the accuracy of subsequent adjustments.
[0034] However, in the prior art, defects such as design or processing accuracy often lead to deviations between the "zero position scale line" on the position indicator line and the "zero position" on the base, and the adjustment accuracy requirements of the slider are relatively high. Slight deviations will also produce large errors, affecting the adjustment accuracy.
[0035] In order to solve at least one of the above-mentioned technical problems or advantages or other advantages, an embodiment of the present invention provides an adjustable triangle seat. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an adjustable triangle seat provided by an embodiment of the utility model. Figure 2 yes Figure 1 As shown in the figure, the adjustable triangle seat includes a base 10, an adjustment mechanism 20, a slider 30 and a position indicating mechanism 40.
[0036] The adjusting mechanism 20 is movably disposed on the base 10 . Specifically, the adjusting mechanism 20 comprises an adjusting knob 21 and an adjusting bolt 22 , one end of the adjusting knob 21 is movably connected to the position indicating mechanism 40 , and the other end of the adjusting knob 21 is movably connected to the adjusting bolt 22 .
[0037] Please combine Figure 1 and Figure 2 See also Figure 3 ,like Figure 3 The adjusting knob 21 is provided with a keyway 211, and the keyway 211 faces the adjusting bolt 22. One end of the adjusting bolt 22 is cut into a non-circular shape and extends into the keyway 211 to be movably connected to the keyway 211. The other end of the adjusting bolt 22 is movably connected to the slider 30. The outer peripheral surface of the adjusting bolt 22 is threadedly connected to the base 10.
[0038] In a specific implementation, the adjusting knob 21 and the adjusting bolt 22 are assembled and installed in the base 10 , and an adjusting slot 212 is provided at one end of the adjusting knob 21 away from the key slot 211 .
[0039] By inserting a wrench corresponding to the shape of the adjustment slot 212 into the adjustment slot 212, the adjustment knob 21 can be rotated, and one end of the adjustment bolt 22 is inserted into the key slot 211 and is in transmission cooperation with the key slot 211, thereby driving the adjustment bolt 22 to rotate. The outer peripheral surface of the adjustment bolt 22 is provided with a thread, and the adjustment bolt 22 is threadedly connected to the base 10 through the thread. When the adjustment bolt rotates, a transmission relationship is established with the base 10, so that the adjustment bolt 22 moves forward or backward.
[0040] The slider 30 is movably disposed on the base 10 . Specifically, a slider groove (not shown in the figure) is disposed on the back of the base 10 . The slider 30 can move up and down in the slider groove. The slider 30 is movably connected to the adjustment mechanism 20 .
[0041] A cam 50 is fixed on the slider 30 , and a cam curved groove 51 is provided on the cam 50 for changing the movement track of the knitting needle.
[0042] On the basis of the above, a cone 221 is provided at one end of the adjusting bolt 22 away from the adjusting knob 21 , and a bevel surface 31 is provided on the side of the slider 30 facing the adjusting bolt 22 , and the cone 221 is slidably connected to the bevel surface 31 .
[0043] When adjusting, the adjusting knob 21 drives the adjusting bolt 22 to rotate, and the adjusting bolt 22 establishes a transmission relationship with the base 10, so that the adjusting bolt 22 moves forward or backward. When the adjusting bolt 22 moves forward (i.e., in the direction of the slider 30), the cone 221 presses the bevel surface 31 forward, so that the slider 30 is pressed downward, driving the cam 50 to move downward, and the cam groove 51 on the cam 50 moves accordingly, thereby changing the movement trajectory of the knitting needle.
[0044] When the adjusting bolt 22 moves backward (i.e., in the direction of the adjusting knob 21), the bevel surface 31 is not squeezed by the cone 221, and the slider 30 moves upward under the action of the return spring 60, driving the cam 50 to move upward, and the cam groove 51 on the cam 50 moves accordingly, thereby changing the movement trajectory of the knitting needle.
[0045] It should be noted that the adjusting knob 21 and the adjusting bolt 22 only transmit rotational torque force, but do not transmit forward or forward and backward driving force, that is, the axial (axial) rotation of the adjusting knob 21 and the adjusting bolt 22 (axial) of the adjusting knob 21 is synchronous, but the axial forward and backward movements between the two are independent of each other and do not affect each other.
[0046] Specifically, when the adjusting knob 21 drives the adjusting bolt 22 to rotate, the front-to-back position of the adjusting knob 21 itself remains unchanged in the axial direction, and the adjusting bolt 22 establishes a transmission relationship with the base 10 due to the threaded connection, so that the adjusting bolt 22 moves axially forward or backward.
[0047] The position indicating mechanism 40 is movably arranged on a side of the base 10 away from the slider 30 , and comprises a first dial 41 and a second dial 42 . The first dial 41 and the second dial 42 are respectively sleeved on the adjusting knob 21 , and the second dial 42 is movably connected to the deceleration assembly 70 .
[0048] Specifically, the reduction assembly 70 is a cycloidal gear, comprising an outer toothed disc 71 and an inner toothed disc 72 . The outer toothed disc 71 is provided with a disc ear 711 movably disposed in the ear groove 11 . The inner toothed disc 72 is movably connected to the adjustment knob 21 , and the outer toothed disc 71 is meshed with the inner toothed disc 72 .
[0049] In some preferred embodiments, an eccentric portion 80 is provided on the adjusting knob 21 , and the inner gear disc 72 is transmission-connected to the eccentric portion 80 .
[0050] In specific implementation, the base 10 is provided with an ear groove 11, and the outer toothed disc 71 is provided with a disc ear 711, and the disc ear 711 is fixed in the ear groove 11 by a fastener 80, so as to fix the outer toothed disc 71 on the base 10. The width W of the ear groove 11 is greater than the width w of the disc ear 711, so that the disc ear 711 has a rotation space in the ear groove 11, and the position of the disc ear 711 in the ear groove 11 can be adjusted by loosening the fastener 80, thereby adjusting the rotation angle of the outer toothed disc 71 in the axial direction, and the inner toothed disc 72 is meshed with the outer toothed disc 71, and the second scale plate is movably connected with the inner toothed disc. When the outer toothed disc 71 rotates, it can also drive the inner toothed disc 72 and the second scale plate 42 to rotate synchronously, so as to adjust the relative position of the "zero position scale line" in the position indicating line on the second scale plate 42 and the "zero position" on the base 10.
[0051] On the basis of the above, a plurality of first connecting grooves 721 are provided on the inner toothed disc 72, and the inner toothed disc 72 is movably connected to the second scale plate 42 through the first connecting grooves 721. Specifically, the adjustable triangle seat further includes a connecting pin 100, one end of which is movably connected to the first connecting groove 721, and the other end of which is movably connected to the second connecting groove 421 on the second scale plate 42.
[0052] In specific implementation, when adjusting the adjusting knob 21, due to the transmission connection between the eccentric part 80 and the inner toothed disc 72, the inner toothed disc 72 is subjected to force to cooperate with the outer toothed disc 71 to perform pendulum deceleration motion, and the connecting pin 100 moves in the first connecting groove 721 to eliminate the influence of the displacement generated during the pendulum deceleration motion of the inner toothed disc 72 on the second scale plate 42.
[0053] Preferably, the number of the first connecting grooves 721 is equal to the number of teeth of the inner gear disc 72 .
[0054] It is understandable that, in the actual production process, the corresponding relationship between the second dial 42 and the first connecting groove 721 can be adjusted by the connecting pin 100 to adjust the overall stroke range of the second dial 42. For example, when the "1-position scale line" (there are multiple scale lines on the dial, marked with 0, 0.5, 1, 1.5, 2... and so on) of the position indicating line on the second dial corresponds to the "zero position" on the base 10, the overall adjustment stroke range of the triangular seat will be reduced by one. The adjustment stroke range can be adjusted according to actual production requirements to improve the adaptability of the second dial 42, and there is no need to manufacture different second dials 42 according to different production requirements, thereby reducing production costs.
[0055] When the number of the first connecting grooves 721 is equal to the number of teeth of the inner gear plate 72 , it can be ensured that when the adjustment stroke range is adjusted, the adjustment range is consistent with the scale line range on the second scale plate 72 .
[0056] In some preferred embodiments, the utility model further provides a circular knitting machine, comprising a plurality of adjustable cam seats as described above. A plurality of high-precision cam seats are sequentially arranged on the circular knitting machine.
[0057] To sum up, compared with the prior art, the adjustable triangle seat and circular loom provided by the utility model are arranged with ear grooves on the base and ears on the outer toothed disc, and the ears are movably arranged in the ear grooves. When there is a deviation between the zero-position scale line in the position indicating line and the zero position on the base, the outer toothed disc is rotated, and the outer toothed disc drives the inner toothed disc to rotate. The inner toothed disc is connected to the position indicating mechanism, and then drives the position indicating mechanism to rotate for fine adjustment, so that the zero-position scale line in the position indicating line corresponds to the zero position on the base, thereby avoiding the problem of error in adjustment accuracy caused by zero-position deviation and affecting the adjustment accuracy.
[0058] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the utility model can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
