Abstract
Description
Technical Field
[0001] The utility model relates to the field of glove machines, in particular to a triangular lifting control structure. Background Art
[0002] There are basically only two types of conventional glove knitting machines on the market. The first type only has the forward needle raising function, and its reverse needle raising is only used for sealing. In the forward needle raising process, the running track of the needle pin is: first rise and fall along the track surface of the elastic needle raising triangle, then rise to the highest point along the track surface of the forward needle raising triangle, and then fall along the track to the bottom of the forward density triangle to complete a unidirectional knitting that first weaves the elastic and then the yarn.
[0003] The second type: It has both forward and reverse needle casting functions. This type of knitting glove machine is called jacquard glove machine or computer flat knitting machine in the industry. If reverse needle casting is performed after forward needle casting in the same knitting row, the running trajectory of the needle pin is: after passing through the bottom of the elastic density triangle, it also moves through the bottom of the reverse density triangle. This method can achieve reverse needle casting, but it causes serious interference to the entry of the elastic thread, increasing the difficulty of controlling the forward and reverse density triangles.
[0004] In the prior application "CN116623353A" (reference document 1), a cam device capable of switching between single-sided knitting, tuck knitting and bidirectional synchronous knitting was designed. However, since the cam device is only provided with an elastic cam on one side (its Figure 1 , 4 is the right side), so when the rubber band is knitted, the knitting efficiency is low, and the rubber band needle channel borrows the density triangle on the right side, so it is necessary to adopt the control of the right density triangle and the rubber band triangle in linkage, and its control structure is relatively complicated.
[0005] In the applicant's prior application "2024208475421", a bidirectional asynchronous knitting cam device was designed. Although part of the transmission structure was simplified, it still adopted an integrated multi-action arm structure (i.e., the left density push foot 53, the right density push foot 54, the first arc-shaped extension part 21, and the second arc-shaped extension part 22 in the comparative document 1) to control each cam. However, this component has an irregular structure and needs to control multiple functional cams. Therefore, it is difficult to process and needs to be replaced once worn.
[0006] Therefore, the inventor conducted further research and developed a triangular lifting control structure, which resulted in the present invention. Utility Model Content
[0007] The utility model aims to provide a triangular lifting control structure, which reduces the processing difficulty of the triangular control structure and facilitates maintenance and replacement.
[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0009] A triangular lifting control structure, comprising
[0010] The action arm is driven by the guide rod through the bearing to swing, one end of the action arm is linked with the transfer arm, and the other end is linked with the needle raising triangle, and at the same time, the action arm is reset by the first tension spring;
[0011] The transfer arm is located above the action arm, and the upper end of the transfer arm is linked with the lifting slider, the lifting slider is used to control the middle triangle, and a second tension spring is arranged on the transfer arm to make the transfer arm and the lifting slider close to each other;
[0012] The lifting slide block is connected with the third tension spring for resetting.
[0013] The above structure is arranged on the triangular bottom plate, and is located on the back of various functional triangles;
[0014] It is an existing technology that the working arm is driven by a guide rod. The guide rod applies pressure to the bearing to make the working arm swing along its pivot axis, thereby lifting the needle raising triangle on the other side; the needle raising triangle corresponds to the needle raising triangle of the comparative document 1, and the middle triangle corresponds to the middle triangle of the comparative document 1. The linkage method between the working arm and the needle raising triangle is consistent with that of the comparative document 1.
[0015] Furthermore, one end of the first tension spring is arranged on the pivot shaft of the transfer arm, and the other end is arranged above the pivot shaft of the action arm.
[0016] Furthermore, a slide groove is arranged in the lifting slider, an axle pin is arranged in the slide groove, and the axle pin is linked with the middle triangle.
[0017] The lifting slide block is pushed by the transfer arm, so that when the shaft pin moves in the slide slot, the position relative to the triangular bottom plate changes, thereby causing the middle triangle to move relative to the triangular bottom plate.
[0018] Furthermore, the second tension spring and the lifting slider are located on the same side of the transfer arm.
[0019] Since the lifting slide block is pushed by the transfer arm, the second tension spring can be arranged to ensure that the lifting slide block is in close contact with the transfer arm.
[0020] Furthermore, the third tension spring and the lifting slider are located on both sides of the transfer arm.
[0021] Since the third tension spring plays a role in resetting the lifting slider, the tension applied by the third tension spring needs to be opposite to the thrust of the transfer arm.
[0022] Furthermore, a limiting groove is provided at the position where the lifting slide block contacts the action arm.
[0023] The limiting groove is used to limit the action arm so that it is not easy to slide in the direction perpendicular to the triangular bottom plate.
[0024] After adopting the above scheme, the utility model has the following advantages compared with the prior art:
[0025] By replacing the original multi-action arm with an action arm, a transfer arm, a lifting slide block, etc., the structure of each component is simplified while ensuring the original function, and each component can be disassembled and installed separately, reducing maintenance costs.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] like Figure 1 , 2 As shown, a triangle lifting control structure is arranged on the back side of the triangle base plate 1 (generally, the side where various triangles are located is the front side). Compared with the prior art, it mainly sets up the mutual linkage between the elements such as the action arm 2, the transfer arm 3, and the lifting slider 4, replacing the original multi-action arm 2 structure to realize the control of the triangle.
[0036] Specifically, taking the direction shown in the figure as an example, the action arm 2 is arranged below the triangular base plate 1, and is provided with a bearing 21. The bearing 21 can be subjected to the thrust of the guide rod, thereby driving the action arm 2 to swing, and the action arm 2 uses its pivot axis as the rotation axis; the right end of the action arm 2 is provided with an inclined surface, and the inclined surface is located below the bushing 51. The bushing 51 is connected to the needle raising triangle 5. Through the swing of the action arm 2, the inclined surface is inserted under the bushing and its position is lifted, so that the needle raising triangle 5 on the other side can be extended and retracted relative to the triangular base plate; the left end of the action arm 2 is located below the transfer arm 3. When swinging, the action arm 2 has an upward thrust on the transfer arm 3, so that the transfer arm 3 swings relative to its own pivot axis.
[0037] The upper end of the transfer arm 3 is linked with the lifting slider 4 and is located in the limiting groove 42 on the left side of the lifting slider 4 (refer to Figure 3 ), when the transfer arm 3 is pushed, its upper end moves to the right, so that the lifting slider 4 moves to the right, and a sliding groove 41 close to a Z shape is opened in the lifting slider 4, and a bushing 43 and an axle pin 44 are also provided in the sliding groove 41. The axle pin is linked with the middle triangle 7. When the lifting slider 4 moves to the right, the axle pin is relatively away from the triangular bottom plate, so that the middle triangle 7 undergoes telescopic movement.
[0038] The resetting of the aforementioned action is achieved by respective tension springs after the guide rods are removed.
[0039] For example, a first tension spring 61 is arranged between the action arm 2 and the transfer arm 3, one end of the first tension spring 61 is arranged on the pivot axis of the transfer arm 3, and the other end is arranged above the pivot axis of the action arm 2; when the guide rod removes the force, since this end of the first tension spring 61 on the transfer arm 3 is fixed, the right end of the action arm 2 moves to the left under the action of the first tension spring 61, thereby realizing the resetting of the action arm 2.
[0040] The resetting of the lifting slide block 4 is achieved by the third tension spring 63, the right end of which is connected to the lifting slide block 4 (refer to Figure 3 ), the left end of the third tension spring 63 serves as a fixed end. When the action arm 2 is withdrawn, the transfer arm 3 pulls the lifting slider 4 back under the action of the third tension spring 63, thereby returning the middle triangle 7 to its original position.
[0041] A second tension spring 62 is provided on the upper part of the transfer arm 3. The function of the second tension spring 62 is to ensure that the upper end of the transfer arm 3 is always in close contact with the lifting slider 4. Therefore, its tension does not need to be too large, otherwise the third tension spring 63 cannot reset the lifting slider 4.
[0042] The remaining pressing needle triangles and density triangles are also provided with corresponding reset tension springs, but the prior art is adopted in this embodiment and will not be expanded here.
[0043] The positions of the aforementioned starting triangle and middle triangle indicated in the figure are the back sides corresponding to the triangle body, not the structure of the triangle body.
[0044] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
