TECHNICAL FIELD

[0001] The utility model relates to a kind of centering advancing mechanism of rubbering polyester cloth, for a variety of use cord fabric, and need the production line of cord fabric centering. BACKGROUND

[0002] Cord fabric is one of the materials used for handrail belt, and a layer of glue is brushed on the back of the cord fabric to ensure adhesion in the process. The cord fabric needs to be advanced forward under the action of the traction mechanism on the production line, while ensuring that the center line of the cord fabric is consistent with the center line of the production line during the advancing process. At the same time, the folding process of the cord fabric from a plane to a certain shape needs to be completed during this process.

[0003] The cord fabric is not rigid enough to be advanced along the established trajectory without deformation by traditional mechanical limiting. Moreover, because of the rubbering on the back, the rubbering surface cannot contact the guiding object. Contacting the guiding object with the rubbering surface not only increases the friction, but also may damage the rubbering surface layer or get dust, causing product quality problems. SUMMARY

[0006] Preferably, the outer stop block is connected with the mounting bracket on the production line.

[0007] Preferably, the top of the outer stop block is provided with a guide wheel, and the guide wheel is arranged on one side of the inner wall in the centering flange groove.

[0008] Preferably, the front side of the two outer stop blocks is provided with an inlet guide wheel for introducing the cord fabric into the centering flange groove.

[0009] Preferably, the inlet guide wheel is trumpet-shaped, and the distance between the two inlet guide wheels is greater than the distance between the two centering flange grooves.

[0010] Preferably, the top surface of the inlet guide wheel is higher than the top surface of the outer stop block.

[0011] Preferably, an auxiliary tensioning wheel is arranged between the two inner stop blocks for contacting the abdomen of the cord fabric to make it U-shaped.

[0012] Preferably, the inner stop block has an L-shaped structure, with the opening of the L-shaped structure facing downwards and forming a centering folded edge groove with the outer stop block.

[0013] More preferably, the top surfaces of the two inner blocks are on the same plane.

[0014] This invention allows the tire cord fabric to smoothly transition from a flat surface to a U-shape, while ensuring that the center line of the fabric remains aligned with the center line of the production line. This device completely preserves the adhesive layer on the back of the tire cord fabric, guaranteeing the product performance that the adhesive layer should achieve. Attached Figure Description

[0017] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0018] Example

[0019] like Figure 1 As shown, this utility model provides a centering and advancing mechanism for a rubbed polyester fabric. It includes an outer pair of blocks 2, and a pair of inner blocks 3 on the inner sides of the outer blocks 2. The inner blocks 3 are symmetrically arranged around the centerline of the production line. A centering folding groove is formed between the inner blocks 3 and the outer blocks on the same side. During operation, the two edges of the fabric 7 enter the two centering folding grooves respectively. An auxiliary tensioning wheel 5 is provided between the two inner blocks 3 to contact the belly of the fabric 7, making it U-shaped.

[0020] Both outer blocks 2 have inlet guide wheels 6 on their front sides for guiding the curtain fabric 7 into the centering folding groove. The inlet guide wheels 6 are trumpet-shaped, and the distance between the two inlet guide wheels 6 is greater than the distance between the two centering folding grooves. The top surface of the inlet guide wheel 6 is higher than the top surface of the outer block 2. The top of the outer block 2 is provided with a guide wheel 4, which is located on one inner wall of the centering folding groove.

[0021] The inner stop block 3 has an L-shaped structure with its opening facing downwards, forming a centering folded edge groove with the outer stop block 2. The top surfaces of the two inner stop blocks 3 are on the same plane.

[0022] During production, the outer stop 2 is connected to the mounting bracket 1 on the production line. The adhesive-backed fabric 7 faces upwards, with adhesive backing on the bottom, making it slightly sticky. Initially, the material is laid flat, but at the outlet, it needs to be centered in a U-shape. The mounting bracket 1 is installed at the required position on the production line, and other components can be mounted on the mounting bracket 1.

[0023] During installation, a pair of inlet guide wheels 6 are symmetrically installed first. Relative to the outlet, the inlet guide wheels are trumpet-shaped and used to guide the cord fabric 7 into the centering folding groove. The outer stop block 2, inner stop block 3, and guide wheel 4 together form the centering folding groove. The guide wheel 4 and outer stop block 2 are located on the outside of the cord fabric 7. The cross-section of the guide wheel 4 is higher than the plane of the outer stop block 2, so that the adhesive-backed surface is conveyed by the guide wheel 4 during forward movement, preventing sliding friction. The inner stop block 3 is an L-shaped component, forming a guide groove with the outer stop block. The guide groove is wide enough to allow the cord fabric to pass through with gaps on both sides. Simultaneously, the upper edge of the L-shaped structure of the inner stop block 3 is used to position the center of the cord fabric 7. The top surfaces of the two inner stop blocks 3 are at the same height, and the upper edge limits the edge of the cord fabric 7. The two inner stop blocks 3, being at the same height and symmetrical about the production line centerline, ensure that the centerline of the U-shaped cord fabric 7 is aligned with the production line centerline.

[0024] It is worth noting that a support roller 9 can be installed at the feed inlet of this mechanism (e.g., Figure 2 As shown in the diagram, this ensures that the curtain fabric 7 remains in an upward state when it enters the mechanism via the guide roller group 8 and the support roller 9, thus guaranteeing that the edge of the curtain fabric 7 contacts the upper edge of the inner stop block 3. Simultaneously, an auxiliary tensioning roller 5 is included in this mechanism. The auxiliary tensioning roller 5 ensures that the curtain fabric 7 maintains a U-shape. Due to the insufficient rigidity of the curtain fabric 7, uneven force during the transition from a flat surface to a U-shape can lead to a W-shape or wrinkles. The auxiliary tensioning roller 5 acts on the belly of the curtain fabric 7, assisting in its shaping. The inlet guide roller 6 is located at the front end of the outer stop block 2, guiding the curtain fabric 7 into the centering folding groove. The spacing of the inlet guide rollers 6 is greater than the spacing of the centering folding groove, serving a transitional function.

[0025] The aforementioned mechanism is used on the production line and plays a crucial role in the entire process. Since the tire cord fabric is a non-rigid material, its centering deviation can reach ±1mm when operating under this mechanism.
