The achievement of this patent scheme is that it can finely position the density triangle. However, since there are many links in the whole process from the operation of the stepping motor to the change of the position of the density triangle, the structure is relatively complicated, not only consumes a lot of kinetic energy, but also makes the , assembly and maintenance are very troublesome
[0004] The above document B significantly simplifies the structure compared with document A, basically makes up for the lack of document A, and objectively reflects the third page of the patent specification The technical effects of lines 8 to 11 still have the following shortcomings: First, there are still many links to drive the density triangular displacement, that is, the motor with forward and reverse functions drives the cam first, and then the cam drives the clamp arm, and then the cam drives the clamping arm. The clamp arm drives the density triangle that matches the clamp arm through the roller (the roller is set on the density triangle guide block of the density triangle), so the stability and accuracy of the density triangle movement are affected to a certain extent; The springs of the matching spring clips are prone to fatigue, which will affect the cooperation effect between the rollers on the density triangle guide block and the roller cavity of the clamp arm, and eventually cause the density triangle movement to be inaccurate and difficult to meet the weaving requirements. The sparse consistency requirements required by the object; the third is to eliminate the matching gap between the aforementioned roller (the patent is called the second roller) and the roller cavity arranged on the density triangle guide block, and to eliminate the movement deviation of the density triangle. Therefore, a blocking spring is arranged on the triangular bottom plate and at the position corresponding to the density triangular guide block, but the setting of the blocking spring tends to increase the resistance, resulting in an increase in the power consumption of the motor, which is not conducive to saving energy, and the blocking spring is also easy to produce Fourth, since two pairs of motors are required to drive a pair of density triangles respectively, the structure is complex and energy consumption is large, and it is difficult to manufacture, install and maintain, and it is not enough to reflect economical cheapness
[0005] Through the applicant's long-term research, it has been found that the four shortcomings of the above-mentioned document B are essentially due to the unreasonable structure of the drive mechanism that drives the movement of the density triangular guide block and the The density triangle does not have self-recovery function

The invention relates to a density triangle control mechanism of a computer flat knitting machine and belongs to the technical field of knitting machinery. The computer flat knitting machine comprises a triangle bottom plate, a left density triangle and a right density triangle, wherein the left density triangle is provided with a left density triangle guide block; and the right density triangle is provided with a right density triangle guide block. The density triangle control mechanism comprises a base, a motor, a synchronous moving device, a left density triangle resetting device and a right density triangle resetting device, wherein the base is fixed on the triangle bottom plate; an midair cavity is formed in the middle of the side of the base, which is toward the triangle bottom plate; the motor is fixed on the base; a motor shaft extends into the midair cavity; a driving wheel is fixed on the motor shaft; the synchronous moving device is arranged in the midair cavity, is in running fit with the driving wheel and is also matched with the left and right density triangle guide blocks; the left density triangle resetting device is matched with the left density triangle guide block; and the right density triangle resetting device is matched with the right density triangle guide block. The density triangle control mechanism has the advantages that the stability and the accuracy of movement of the left and right density triangles are improved; the requirement of different braided fabrics on the consistency of the required densities is met; energy is saved; and the integral structure of the density triangle control mechanism is simple.
Description
technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to a density triangle control mechanism of a computerized flat knitting machine. Background technique [0002] As known in the industry, the sparse density of different braids is different, and the change of the sparse density of the braid is realized by the position change of the density triangle on the triangular bottom plate, and the position change of the density triangle is achieved through the density triangle The density triangle adjustment mechanism is usually called the density triangle control mechanism or the drive mechanism. The movement trajectory of the knitting needles on the needle bed (also known as the needle plate) is changed by controlling the position of the density triangle by the density triangle control mechanism. [0003] The technical information of the density triangle control mechanism of the aforementioned computerized flat knitti...
