[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0022] Reference Figure 1As shown, the integrated sock knitting machine's sewing toothed disc is a key component of the sock knitting machine (mechanical equipment for knitting socks), mainly used for sewing or reinforcing the knitting parts of socks. The existing traditional 3.5-inch sewing toothed disc, improved from the 3.75-inch specification, has the following defects: an unreasonable bearing mounting cavity design necessitates the addition of an extended step to the fixed needle plate seat; the movable needle plate seat cannot effectively press against the bearing end face, with a pressing range of less than 50%; uneven distribution of the bearing end face pressing force easily leads to axial movement. These problems result in poor equipment operational stability, a product qualification rate of only 82%-85%, and an average downtime for maintenance every 300 hours. To solve these problems, a sewing toothed disc for an integrated knitting and sewing machine is proposed, comprising a sewing toothed disc body 1, a fixed needle plate seat 2, a movable needle plate seat 3, and a bearing 4. Its characteristic is that the sewing toothed disc body 1 is provided with a stepped mounting cavity 101, and the shaft... The bearing 4 is installed in the mounting cavity 101 through a transition fit; the fixed needle plate seat 2 is provided with an annular pressing part 201, the inner wall of which forms a 50% circumferential contact surface with the outer ring of the bearing 4, and is fixed to the end face of the sewing disc body 1 by axially distributed clamping screws 5; the lower end of the movable needle plate seat 3 is provided with an adjustable limiting boss 301, which forms a pressure contact with the upper end face of the bearing 4 when the working state is flat; the arrangement of the sewing disc body, the fixed needle plate seat and the movable needle plate seat can achieve the bearing to be set in a transition fit state, thereby controlling the interference of the inner ring of the bearing, thus avoiding the problem of the bearing not being fixed firmly, and the setting of the annular pressing part of the fixed needle plate seat ensures that the 50% contact surface is evenly stressed, thereby achieving the purpose of uniform stress distribution of the entire structure and ensuring the stability of the structure.

[0023] It should be noted that the inner diameter of the bearing 4 and the mounting cavity 101 of the main body 1 of the slotted disc adopt the H7 / k6 transition fit tolerance grade.

[0024] Furthermore, 4-6 clamping screws 5 are evenly arranged along the circumference, and the depth of the threaded hole is greater than 1.2 times the length of the screw rod.

[0025] It should also be noted that the stepped surface of the stepped mounting cavity 101 is designed to be inclined at a 15-25° angle to the axis.

[0026] In addition, the ratio of the inner diameter of the bearing 4 to the total height of the geared disc is 1:3.8-4.2.

[0027] It should be added that the improved main body 1 of the slotted disc is made of GCr15 bearing steel forging, and the surface hardness reaches HRC58-62 after quenching treatment; the stepped mounting cavity 101 includes: an upper Φ52mm guide section (101a) with a 1:50 tapered guide surface and a lower Φ50mm positioning section (101b) that forms an H7 / k6 transition fit with the outer ring of the bearing. The stepped structure enables the bearing to automatically align during press-fitting, with a coaxiality error ≤0.015mm, which improves the accuracy by 3 times compared to the original structure; the tapered guide reduces assembly impact damage, and the installation qualification rate increases from 78% to 98%.

[0028] It is worth mentioning that the rigid pressing of the fixed needle plate seat 2 and the flexible compensation of the movable needle plate seat 3 are combined to adapt to different working conditions and loads.

[0029] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
