Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a warp knitting machine with a dividing device. Background Technology

[0002] A warp knitting machine is a machine used for weaving textiles. Its main function is to form knitted fabrics by simultaneously forming loops of one or more sets of parallel yarns fed into all the working needles of the machine in the warp direction. A warp knitting machine mainly consists of a knitting mechanism, a guide bar traverse mechanism, a warp feed mechanism, a take-up and tension mechanism, and a transmission mechanism.

[0003] The mechanism of the cutting device can be referenced from the utility model disclosed in "CN213978079U" which describes "a fabric dividing device for a warp knitting machine for producing all-polyester warp-knitted elastic fabric". By setting up a U-shaped block and a rubber pressure plate to fix the fabric, and then dividing it with a cutter, it can effectively avoid large tears at the cut of the fabric. This solves the problem that existing dividing devices have a large tension on the fabric during dividing, which easily leads to large tears at the cut, requiring subsequent trimming, which is time-consuming and laborious.

[0004] However, the guide roller in the above device does not have a good limiting component, which can easily cause deviation during the fabric conveying process. The deviation of the fabric will lead to inaccurate cutting position, resulting in the cut fabric not meeting the size requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a warp knitting machine with a dividing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A warp knitting machine with a dividing device includes a warp knitting machine body, a worktable is provided on one side of the warp knitting machine body, a cutting component and a take-up roller component are sequentially provided on the top of the worktable, and auxiliary limiting components are provided on both sides of the cutting component on the top of the worktable.

[0008] The auxiliary limiting component includes two fixed seats, two fixed shafts are installed at equal distances between the two fixed seats, and a limiting roller body is fixedly sleeved on the outer wall of the upper fixed shaft between the two fixed seats, and a conveying roller body is fixedly sleeved on the outer wall of the lower fixed shaft between the two fixed seats. A cavity is opened at the bottom of the outer wall of the limiting roller body, and an auxiliary roller assembly is arranged in the cavity.

[0009] A bidirectional screw drive assembly is provided above the two fixed seats. Two limiting members are symmetrically arranged between the two fixed seats through the bidirectional screw drive assembly. Both limiting members are slidably arranged outside the conveyor roller body and the limiting roller body.

[0010] Furthermore, in a preferred configuration, the auxiliary roller assembly includes a limiting shaft, and the outer wall of the limiting shaft is fitted with the auxiliary roller body.

[0011] Furthermore, in a preferred configuration, the limiting member is in the shape of an "8", and a through hole is provided inside the limiting member at the conveyor roller body, and a groove is provided inside the limiting member at the auxiliary roller assembly and the limiting roller body.

[0012] In addition, a preferred structure is that T-shaped limiting sliders are symmetrically installed on both sides of the groove, and limiting grooves are opened on both sides of the limiting roller body at the T-shaped limiting sliders.

[0013] Furthermore, in a preferred configuration, the bidirectional lead screw drive assembly includes a bidirectional lead screw body, with two nut pairs symmetrically arranged on the outer wall of the bidirectional lead screw body, and the bottom of the nut pairs being connected to a limiting member. The bidirectional lead screw body is driven by a drive motor.

[0014] In addition, a preferred structure is that the take-up roller body includes two limiting seats, a rotating shaft is provided between the two limiting seats, the rotating shaft is driven by a second drive motor, one side of the rotating shaft is connected to the second drive motor, the other side of the rotating shaft is connected to the limiting seat through a bearing, and the take-up roller body is fixedly sleeved on the outer wall of the rotating shaft.

[0015] The beneficial effects of this utility model are as follows:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A warp knitting machine with a dividing device includes a warp knitting machine body 1, a worktable 2 is provided on one side of the warp knitting machine body 1, a cutting component 3 and a take-up roller component are sequentially provided on the top of the worktable 2, and auxiliary limiting components 4 are provided on both sides of the top of the worktable 2 located on the cutting component 3.

[0025] Furthermore, the auxiliary limiting component 4 includes two fixed seats 41, two fixed shafts are installed at equal distances between the two fixed seats 41, and a limiting roller body 43 is fixedly sleeved on the outer wall of the upper fixed shaft between the two fixed seats 41, and a conveying roller body 42 is fixedly sleeved on the outer wall of the lower fixed shaft between the two fixed seats 41. A cavity is opened at the bottom of the outer wall of the limiting roller body 43, and an auxiliary roller assembly 46 is provided in the cavity.

[0026] Meanwhile, a bidirectional screw drive assembly 45 is provided above the two fixed seats 41, and two limiting members 44 are symmetrically arranged between the two fixed seats 41 through the bidirectional screw drive assembly 45. Both limiting members 44 are slidably arranged outside the conveyor roller body 42 and the limiting roller body 43.

[0027] Furthermore, the auxiliary roller assembly 46 includes a limiting shaft, and the outer wall of the limiting shaft is fitted with the auxiliary roller body.

[0028] Furthermore, the limiting member 44 is in the shape of an "8", and a through hole is provided in the limiting member 44 at the location of the conveyor roller body 42. A sliding groove is provided in the limiting member 44 at the location of the auxiliary roller assembly 46 and the limiting roller body 43.

[0029] Furthermore, T-shaped limit sliders 441 are symmetrically installed on both sides of the groove, and limit grooves 431 are opened on both sides of the limit roller body 43 at the T-shaped limit sliders 441.

[0030] Furthermore, the bidirectional lead screw drive assembly 45 includes a bidirectional lead screw body, with two nut pairs symmetrically arranged on the outer wall of the bidirectional lead screw body, and the bottom of the nut pairs is connected to the limiting member 44.

The other side of the rotating shaft is connected to the limiting seat through a bearing. The take-up roller body is fixedly sleeved on the outer wall of the rotating shaft.

[0032] It is worth noting that the specific structure and working principle of the cutting component 3, the bidirectional screw drive component 45, the take-up roller component, and the warp knitting machine body 1 are all existing technologies that are currently publicly available on the market, and are not the main technical problems that this utility model needs to solve.

[0034] Meanwhile, it is worth noting that the outer walls of both the conveyor roller body 42 and the auxiliary roller body are made of rubber, which can effectively increase the friction between the conveyor roller and the fabric during the conveying process, prevent the fabric from shifting or moving during the conveying process, and ensure the accuracy of the cutting component in cutting the fabric.

[0035] Meanwhile, during the movement of the limiting component 44, the stability of the limiting component 44 is ensured by the T-shaped limiting slider 441.
