Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a double-density triangle adjustment mechanism. Background Art

[0002] The basic structure of the computer glove machine is: between the left and right bases, there are front and rear needle beds, movable knitting needles are arranged in the needle grooves of the needle beds, and cam bottom plates are arranged on the split front and rear heads, and the cam bottom plates move left and right with the heads; because various cams are arranged on the cam bottom plates, the needles are selected, started and cleared through the interaction of the needle butts of the cams and the knitting needles (combination needles), so as to complete various knitting functions.

[0003] The density triangle is used to control the tightness and size of the glove coils, and there are many ways to control it. The applicant has applied for a triangle and its control mechanism for a flat knitting machine in the published patent CN210529180U, which drives the push rod downward to move the density triangle (the mesh triangle in this article is the density triangle) downward.

[0004] Based on the above principle, the applicant proposed a glove knitting process in CN117026490A, which aims to achieve double-sided synchronous knitting on a glove machine. In the double-sided knitting process, the movement amplitudes of the two density triangles set on the left and right sides of a triangle bottom plate must be consistent, otherwise the problem of inconsistent knitting density will occur in the same glove.

[0005] Therefore, the inventor conducted further research and developed a dual-density triangle adjustment mechanism, which resulted in the present invention. Utility Model Content

[0006] The utility model aims to provide a double-density triangle adjustment mechanism, which can ensure that the movement amplitudes of the left and right density triangles on the same triangle bottom plate remain consistent.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A double-density triangle adjustment mechanism, comprising

[0009] A triangular bottom plate is provided with a first density triangle and a second density triangle, and sliding blocks are provided correspondingly to the first density triangle and the second density triangle, and the sliding blocks are all slidably arranged in the sliding groove of the triangular bottom plate, wherein the top of the sliding block of at least one density triangle is against the arc surface of the cam or the eccentric wheel, and the cam or the eccentric wheel is linked with the push rod, and the push rod is pressed down by the same control rod, thereby driving the two density triangles to move downward.

[0010] Since the distance between the arc surface of the cam or the eccentric wheel and its center is continuously changing, by adjusting the cam or the eccentric wheel, when the control rod is pressed down, the sliding blocks of the first density triangle and the second density triangle can have the same downward movement distance, thereby ensuring the consistency of the tightness of the knitted gloves.

[0011] Furthermore, a locking piece is provided on the cam or the eccentric wheel, and when the adjustment is completed, the locking piece prevents the cam or the eccentric wheel from rotating any more.

[0012] The locking parts are generally bolts and nuts.

[0013] Furthermore, the width of the contact surface between the push rod and the cam or the eccentric wheel is greater than the diameter of the cam or the eccentric wheel.

[0014] Too little contact between the push rod and the cam or eccentric may cause the two to separate.

[0015] Furthermore, the push rods linked with the first density triangle and the second density triangle are all pivotally connected to the same connecting rod of the triangle bottom plate.

[0016] Furthermore, a rotatable bearing is arranged on the push rod, and the bearing is in direct contact with the control rod.

[0017] This technical feature has been applied in CN210529180U.

[0018] Furthermore, the push rod is a curved structure, and the protrusion of the curved part is upward.

[0019] This technical feature is similar to that in CN210529180U, and the specific structure has been adjusted according to actual conditions.

[0020] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0021] By fine-tuning the cam or the eccentric wheel, when the control rod presses down the push rod, the downward movement amplitudes of the left and right sliding blocks are consistent, thereby ensuring the consistency of the tightness of knitting the same glove.

[0026] Density triangle (11, 12), sliding block (21, 22), eccentric wheel (31, 32),

[0027] Push rod (41, 42), bearing (51, 52), locking member (61, 62),

[0028] Triangular bottom plate 7, connecting rod 8. DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1 , 2 As shown, a double-density triangle adjustment mechanism comprises a triangle bottom plate 7, two density triangles (11, 12) are arranged on one side of the triangle bottom plate 7, sliding blocks (21, 22) are arranged on the other side corresponding to the density triangles (11, 12), the density triangles (11, 12) are connected to the sliding blocks (21, 22), and the parts where the sliding blocks (21, 22) are connected to the density triangles (11, 12) are located in the sliding grooves of the triangle bottom plate 7 and can slide relatively (this part of the sliding blocks (21, 22) can be an integrated structure; it can also be a split structure to facilitate installation, such as Figure 3 shown).

[0031] A corresponding push rod (41, 42) is arranged above each sliding block (21, 22), and the two push rods (41, 42) are pivotally connected to the same connecting rod 8 of the triangular bottom plate 7. The push rods (41, 42) are both curved structures, and the protrusion of the curved part is upward. A rolling bearing (51, 52) is arranged on the side of the curved part. The bearing (51, 52) is used to contact with the horizontal control rod (this control method has been disclosed in the previous patent). By pressing the control rod downward, the push rod (41, 42) applies pressure to the sliding block (21, 22), so that the density triangle (11, 12) moves downward to change the tightness of the knitted gloves. The rise of the density triangle (11, 12) is generally reset by setting a reset spring. The operation mode of the above-mentioned density triangle (11, 12) is a technical content disclosed in the art, and this operation mode is adopted in this application.

[0032] The main improvements of this application are:

[0033] An eccentric wheel (31, 32) is arranged between the top of the sliding block (21, 22) and the push rod (41, 42) so as to relatively change the distance between the two, so that the top of the sliding block (21, 22) abuts against the arc surface of the eccentric wheel (31, 32), and the eccentric wheel (31, 32) abuts against one end of the push rod (41, 42). Due to various reasons, the moving distances of the two density triangles (11, 12) under the action of the push rod (41, 42) may be different. By arranging the eccentric wheel (31, 32), the two density triangles (11, 12) can have a consistent moving distance under the action of the push rod (41, 42) by rotating fine adjustment; when the adjustment is completed, the eccentric wheel (31, 32) is stopped from rotating by the locking member (61, 62).

[0034] In order to ensure that the top of the sliding block (21, 22) does not separate from the arc surface of the eccentric wheel (31, 32), the width of the contact surface between the push rod (41, 42) and the eccentric wheel (31, 32) is greater than the diameter of the eccentric wheel (31, 32).

[0035] 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.
