Description

Technical Field

[0001] This utility model relates to the field of curtain fabric production technology, and more specifically to a negative pressure adhesive suction device for impregnated curtain fabric. Background Technology

[0002] In the production of rubber-impregnated tire cord fabric, the impregnation process is crucial, directly determining the bonding strength between the fabric and the rubber, as well as the mechanical properties of the final product. To ensure that the amount of adhesive applied to the impregnated tire cord fabric precisely meets customer requirements, a negative pressure adhesive suction device is commonly used in production. After the tire cord passes through the impregnation tank, the negative pressure adhesive suction device removes excess adhesive from its surface using vacuum suction, thereby achieving precise control over the amount of adhesive applied.

[0003] The distance between the suction port and the fabric surface is a core parameter affecting the adhesive absorption effect and fabric quality. This distance is particularly sensitive and critical for loosely structured, low-warp-density tire cord fabrics with large weft spacing. In actual production, especially when producing small-sized, low-warp-density tire cord fabrics, existing negative pressure adhesive absorption devices and their adjustment methods have revealed significant technical limitations.

[0004] If the distance is too close, the strong vacuum suction will directly act on the less stable weft threads, easily causing them to shift or twist, thus damaging the inherent uniform mesh structure of the fabric and resulting in serious fabric quality problems. If the distance is too far, the vacuum suction will decrease sharply, failing to effectively remove excess adhesive, leading to excessive adhesive application and failure to meet customer technical specifications.

[0005] Existing adjustment methods mostly rely on the operator's experience and visual observation, lacking precise quantitative basis, and cannot achieve the optimal distance, resulting in significant fluctuations in product quality control. Summary of the Invention

[0006] To address the technical problems existing in current negative pressure adhesive suction devices, this utility model proposes a negative pressure adhesive suction device for impregnated curtain fabric, comprising: The first guide roller and the second guide roller are connected by a rubber-impregnated cord fabric that passes around the first guide roller and the second guide roller in sequence, forming a linear path between the first guide roller and the second guide roller. A first support structure is provided on the first side of the line path; A second support structure is provided on the second side of the line path; Two adhesive suction components are provided: a first adhesive suction component disposed on a first support structure and a second adhesive suction component disposed on a second support structure. The adhesive suction port of the first adhesive suction component faces the thread path of the dipped fabric, and the adhesive suction port of the second adhesive suction component also faces the thread path of the dipped fabric. The adhesive-absorbing component includes a main structure and a scale on the surface of the main structure. The adhesive-absorbing component is configured to move on the first support structure or the second support structure to change the distance between the adhesive-absorbing port and the thread path of the glue-impregnated fabric. The first support structure and the second support structure are provided with markers. When the adhesive-absorbing component moves to different positions, the markers indicate different positions on the scale to characterize the relative position of the adhesive-absorbing component and the thread path of the glue-impregnated fabric.

[0007] Preferably, the first end of the main structure is provided with a glue suction port, and the second end is connected to a negative pressure adsorption device, which adsorbs the glue layer on the surface of the glue-impregnated curtain fabric by generating negative pressure at the glue suction port.

[0008] Preferably, the bottom of the adhesive suction component is provided with a guide rail or roller structure, so that the adhesive suction component can move on the surface of the first support structure or the second support structure.

[0009] Preferably, the first support structure and the second support structure are provided with linear drive components, the fixed end of the linear drive components is connected to the first support structure or the second support structure, and the drive end of the linear drive components is connected to the adhesive suction component.

[0010] Preferably, the linear drive component includes a threaded sleeve and a threaded rod. The threaded sleeve is fixed to the first support structure or the second support structure, and the threaded rod is threadedly connected to the threaded sleeve and is drively connected to the adhesive suction component.

[0011] Preferably, the scale is a stainless steel scale, which is welded to the surface of the adhesive-absorbing component.

[0012] Preferably, the marker is configured as a pointer structure with a tip that extends to the scale mark of the ruler. When the adhesive-absorbing component moves, the tip of the marker indicates the position of different scale mark on the ruler.

[0013] Preferably, the suction ports of the first and second adhesive suction components are set to have the same distance from the thread path of the dipped fabric.

[0014] Compared with the prior art, the advantages of this utility model are: This application precisely quantifies the distance between the adhesive suction port and the fabric surface of the curtain by installing a scale on the adhesive suction device and adding indicator marks to the support structure. This effectively ensures the uniformity and stability of the adhesive suction effect, not only strictly controlling the amount of adhesive applied within the customer's requirements, but also avoiding fabric quality problems such as weft displacement caused by improper distance. In addition, it can significantly reduce the difficulty of operation and the reliance on personnel experience, making the production process have the standardized characteristics of being recordable and reproducible, and significantly improving the consistency of product quality. Attached Figure Description

[0015] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein: Figure 1 This is a schematic diagram showing the difference in adhesive absorption caused by the different spacing between the adhesive-absorbing components located on both sides of the adhesive-impregnated curtain fabric as shown in this utility model; Figure 2 This is a schematic diagram of the structure of the negative pressure adhesive absorption device for the impregnated curtain fabric shown in this utility model; Figure 3 This is a schematic diagram showing that the adhesive-absorbing component of this utility model is located at a fixed distance between the two sides of the adhesive-impregnated curtain fabric. Detailed Implementation

[0016] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, the dipped fabric 10 has adhesive layers on both sides, namely the first adhesive layer 101 and the second adhesive layer 102. If the adhesive-absorbing components on both sides are positioned differently from the sides of the dipped fabric 10, it can easily result in one side having a thicker adhesive layer and the other side having a thinner adhesive layer. For example... Figure 1 As shown, the adhesive suction component on the right is farther away, resulting in a thicker first adhesive layer 101, while the adhesive suction component on the left is closer away, resulting in a thinner second adhesive layer 102.

[0018] It should be understood that in actual operation, it is difficult for users to control the distance between the glue suction port of the glue suction component on both sides of the curtain fabric and the curtain fabric completely consistent based on experience. Therefore, this leads to a large fluctuation in the quality control of the curtain fabric.

[0019] Combination Figure 2 As shown, a negative pressure adhesive suction device for dipped cord fabric includes a first guide roller 12, a second guide roller 11, a first support structure 13, a second support structure 14, and two adhesive suction components 20.

[0020] Furthermore, the dipped cord fabric passes sequentially around the first guide roller 12 and the second guide roller 11, forming a linear thread path between the first guide roller 12 and the second guide roller 11. The first support structure 13 is disposed on the first side of the thread path, and the second support structure 14 is disposed on the second side of the thread path.

[0021] In an optional embodiment, the first support structure 13 and the second support structure 14 are machine platform structures respectively arranged on both sides of the line path.

[0022] The two adhesive suction components 20 are a first adhesive suction component 201 disposed on the first support structure 13 and a second adhesive suction component 202 disposed on the second support structure 14. The adhesive suction port of the first adhesive suction component 201 faces the thread path of the dipped fabric, and the adhesive suction port of the second adhesive suction component 202 also faces the thread path of the dipped fabric.

[0023] Thus, the first adhesive-absorbing component 201 can absorb adhesive from the first side of the glue-impregnated fabric, and the second adhesive-absorbing component 202 can absorb adhesive from the second side of the glue-impregnated fabric.

[0024] Optionally, the first end of the main structure 21 is provided with a suction port, and the second end is connected to a negative pressure adsorption device, which adsorbs the adhesive layer on the surface of the impregnated curtain fabric by generating negative pressure at the suction port.

[0025] Furthermore, in order to accurately control the distance between the glue suction port of the two glue suction components and the curtain fabric, it is necessary to quantify the distance between the glue suction component 20 and the curtain fabric. Specifically, the glue suction component 20 includes a main structure 21 and a scale 22 set on the surface of the main structure 21.

[0026] The adhesive suction component 20 is configured to move on the first support structure 13 or the second support structure 14 to change the distance between the adhesive suction port and the thread path of the impregnated fabric, and the first support structure 13 and the second support structure 14 are provided with marking elements 16.

[0027] Thus, when the adhesive suction component 20 moves to different positions, the marker 16 indicates the different positions on the scale 22 to characterize the current relative position of the adhesive suction component 20 and the thread path of the dipped fabric.

[0028] In an optional embodiment, combined with Figure 2 As shown, the bottom of the adhesive suction component 20 is provided with a guide rail or roller structure 23, so that the adhesive suction component 20 can move on the surface of the first support structure 13 or the second support structure 14.

[0029] Specifically, the first support structure 13 and the second support structure 14 are provided with linear drive components 15. The fixed end of the linear drive component 15 is connected to the first support structure 13 or the second support structure 14, and the drive end of the linear drive component 15 is connected to the adhesive suction component 20.

[0030] The linear drive component 15 includes a threaded sleeve 151 and a threaded rod 152. The threaded sleeve 151 is fixed to the first support structure 13 or the second support structure 14, and the threaded rod 152 is threadedly connected to the threaded sleeve 151 and is connected to the adhesive suction component 20 in a transmission manner.

[0031] Thus, when the threaded rod 152 is rotated, the threaded rod 152 and the threaded sleeve 151 rotate relative to each other, causing the adhesive suction component 20 to produce a slight displacement. By using this precise adjustment of the spacing, the spatial position of the adhesive suction component 20 can be controlled.

[0032] In a specific embodiment, since the first support structure 13, the second support structure 14 and the thread path of the glue-impregnated curtain fabric have a fixed spatial positional relationship, when the glue-absorbing component 20 moves, the relative positional relationship between the scale 22 and the marker 16 also changes, and the scale 22 can quantify this positional change.

[0033] like Figure 3 As shown, in a preferred embodiment, the setting position of the scale 22 is determined according to the position of the first support structure 13, the second support structure 14 and the thread path of the glue-impregnated curtain fabric, that is, the positional relationship between La and Lb is obtained. The size data is measured in advance using tools, and the scale 22 is welded to the predetermined position on the surface of the glue-absorbing component 20. That is, the relationship between the marker 16 and the scale 22 directly represents the distance relationship between the glue-absorbing port of the glue-absorbing component 20 and the thread path of the glue-impregnated curtain fabric. In other words, the data of L1 and L2 can be seen intuitively through the scale 22.

[0034] In this way, workers can precisely adjust the positional relationship between the glue suction port and the glue-impregnated fabric, especially controlling the consistent relative distance between the two glue suction components 20 and the glue-impregnated fabric. Specifically, the glue suction ports of the first and second glue suction components 201 are set to have the same distance from the thread path of the glue-impregnated fabric. This ensures the consistency of the glue suction port process parameters between different batches, guarantees the same glue suction effect, and increases process stability.

[0035] In the above embodiments, the scale 22 can be a stainless steel scale, which is welded to the surface of the adhesive absorption component 20.

[0036] Furthermore, the marker 16 is configured as a pointer structure with a tip that extends to the scale mark of the ruler 22. When the adhesive suction member 20 moves, the tip of the marker 16 indicates the position of different scale mark on the ruler 22.

[0037] Thus, the stainless steel ruler and stainless steel pointer structure ensures the durability and reliability of the device, while also having a low modification cost.

[0038] In conjunction with the above embodiments, this application, by installing a scale on the glue suction device and adding indicator markers to the support structure, precisely quantifies the distance between the glue suction port and the fabric surface of the curtain fabric, thereby effectively ensuring the uniformity and stability of the glue suction effect. This not only ensures that the amount of glue applied is strictly controlled within the range required by the customer, but also avoids fabric quality problems such as weft displacement caused by improper distance. In addition, it can significantly reduce the difficulty of operation and the dependence on personnel experience, enabling the production process to have standardized characteristics that are recordable and reproducible, and significantly improving the consistency of product quality.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
