Description

Technical Field

[0001] This utility model relates to the field of warp knitting technology, and in particular to a conveyor roller for 3D warp knitting. Background Technology

[0002] Traditional 3D warp-knitted fabrics (refer to the existing patent for a 3D warp-knitted mesh mat, patent publication number "CN218090028U", application date: 2022.07.26) need to be conveyed by conveyor rollers after being processed and formed. In order not to damage the formed 3D warp-knitted fabric during the conveying process, the existing method is to wrap a layer of plush felt on the outer edge of the conveyor roller. The plush felt increases the contact friction with the 3D warp-knitted fabric, and the 3D warp-knitted fabric is conveyed under the action of friction. However, after working for a period of time, the plush felt will be worn flat or smooth by the 3D warp-knitted fabric, which will reduce the surface friction between the plush felt and the 3D warp-knitted fabric, or even eliminate the friction. This will cause slippage and prevent the 3D warp-knitted fabric from being conveyed, affecting normal operation. Utility Model Content

[0003] The purpose of this invention is to provide a conveyor roller for 3D warp-knitted fabric processing, which solves the problem that existing conveyor rollers slip, cannot convey 3D warp-knitted fabric, and affect normal operation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a conveyor roller for 3D warp-knitted fabric processing, including a mandrel. An inner connecting layer and an outer conveyor layer are sequentially wrapped on the outer edge surface of the mandrel from the inside to the outside in the radial direction. The inner connecting layer is fixed on the outer edge surface of the mandrel. The outer edge surface of the outer conveyor layer is densely covered with a plurality of protrusions. The arrangement of the plurality of protrusions on the outer conveyor layer corresponds to the arrangement of the knitting holes on the 3D warp-knitted fabric. The radial length of the protrusions is less than the depth of the knitting holes of the 3D warp-knitted fabric. The inner connecting layer is made of a flexible material, and the outer conveyor layer is detachably connected to the inner connecting layer.

[0006] Furthermore, the outer transmission layer and the inner connection layer are connected by pins.

[0007] Furthermore, the inner edge surface of the outer transmission layer is provided with a plurality of limiting protrusions along its circumference, and the outer edge surface of the inner connecting layer is provided with a limiting groove that cooperates with the limiting protrusions.

[0008] Furthermore, the outer conveying layer is made of stainless steel sheet, and the protrusion is also made of stainless steel. The outer conveying layer and the protrusion are integrally formed.

[0009] Furthermore, the radial outer edge of the protrusion is arc-shaped.

[0010] Furthermore, the radial outer edge of the protrusion is planar.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model provides a conveyor roller for processing 3D warp-knitted fabric, comprising a mandrel. An inner connecting layer and an outer conveyor layer are sequentially wrapped radially from the inside out on the outer edge of the mandrel. The inner connecting layer is fixed to the outer edge of the mandrel. The outer edge of the outer conveyor layer is densely covered with a plurality of protrusions, the arrangement of which corresponds to the arrangement of the knitting holes on the 3D warp-knitted fabric. The radial length of each protrusion is less than the depth of the knitting holes in the 3D warp-knitted fabric. The inner connecting layer is made of a flexible material, and the outer conveyor layer is detachably connected to the inner connecting layer. When this conveyor roller conveys the processed 3D warp-knitted fabric, the protrusions are embedded within the knitting holes, causing the fabric to move during rotation. This process minimizes slippage, ensuring normal conveying of the 3D warp-knitted fabric and improving conveying efficiency. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] refer to Figures 1-4 The present invention provides a conveyor roller for 3D warp-knitted fabric processing, including a mandrel 1, and an inner connecting layer 2 and an outer conveyor layer 3 are sequentially wrapped on the outer edge surface of the mandrel 1 from the inside to the outside along the radial direction.

[0026] refer to Figures 1-4 The inner connecting layer 2 is made of a flexible material, such as plastic. The inner edge of the inner connecting layer 2 is glued to the outer edge of the mandrel 1. The outer edge of the outer conveying layer 3 is densely covered with several protrusions 4, the arrangement of which corresponds to the arrangement of the knitting holes on the 3D warp-knitted fabric. When the conveyor roller of this structure rotates, the protrusions 4 on the outer conveying layer 3 are engaged in the corresponding knitting holes of the processed 3D warp-knitted fabric, thereby driving the processed 3D warp-knitted fabric to move, preventing slippage. The radial outer edge of the protrusion 4 is arc-shaped, facilitating its engagement in the knitting holes and protecting the 3D warp-knitted fabric from puncture or cut. The radial length of the protrusion 4 is less than the depth of the knitting hole, allowing it to easily detach from the knitting hole when the conveyor roller rotates to convey the 3D warp-knitted fabric.

[0027] refer to Figures 1-4The outer conveying layer 3 is detachably connected to the inner connecting layer 2 via pins 5. These pins 5 are needle-shaped pins with end caps, which facilitates fixing the outer conveying layer 3 to the inner connecting layer 2. Simultaneously, this connection allows for easy disassembly of the outer conveying layer 3 after prolonged use and wear of the protrusion 4. In this example, the pins 5 with end caps are hidden within the protrusion 4, ensuring uninterrupted operation during the conveying of the 3D warp-knitted fabric.

[0028] refer to Figures 1-4 The outer conveying layer 3 is made of stainless steel sheet, which makes it easy for the outer conveying layer 3 to wrap around the inner connecting layer 2. The protrusion 4 is also made of stainless steel. The outer conveying layer 3 and the protrusion 4 are integrally formed. The stainless steel material has high wear resistance and extends service life. The outer edges of the protrusion 4 and the outer conveying layer 3 are both smooth, which makes it less likely for snagging to occur when conveying 3D warp-knitted fabric.

[0029] refer to Figures 1-4 Multiple limiting protrusions 6 are provided along the circumference of the inner edge surface of the outer conveying layer 3, and limiting grooves 7 that cooperate with the limiting protrusions 6 are provided on the outer edge surface of the inner connecting layer 2. Through the cooperation of the limiting protrusions 6 and the limiting grooves 7, the limiting function is played in the circumferential direction, thereby improving the firmness of the outer conveying layer 3 and preventing loosening and rotation in the circumferential direction.

[0030] In summary, when the conveyor roller of this structure conveys the processed 3D warp-knitted fabric, the protrusions 4 on it are tied into the knitting holes. During the rotation, the 3D warp-knitted fabric is moved, and slippage is not likely to occur during this process, resulting in high conveying efficiency.

[0031] Example 2

[0032] refer to Figure 5 The content of this embodiment is basically the same as that of Embodiment 1, except that:

[0033] The radial outer edge of the protrusion 4 is set in a plane, which also makes it easy to tie it into the knitting hole, thus protecting the 3D warp-knitted fabric and making it less likely to be punctured or cut.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
