AI Technical Summary
In existing automotive roof single-layer PU fabric roller coating machines, when the coating roller applies glue to the front of the single-layer PU fabric, the fabric tends to stick and roll up, preventing it from moving forward normally.
Multiple air jet modules are set in front of the glue coating roller. The air jet modules spray air obliquely to the rear and lower to blow off the front of the fabric. At the same time, sensors and timers are used to control the timing of the air jets. Combined with heaters, the air jets are heated to prevent the glue from solidifying. The grippers hold the fabric on both sides to assist in moving it forward.
This effectively prevents the front of the fabric from being rolled up by the adhesive roller, ensuring that the fabric moves forward smoothly and is coated with adhesive, thus improving production efficiency and product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile roof manufacturing, and in particular to a roll bonding machine for single-layer automobile roof fabric. Background Technology
[0002] like Figure 3 As shown, the existing single-layer PU fabric roller coating machine for automotive headliners includes a base 1. Above the base 1, from back to front, are a feeding roller 3 and an adhesive roller 4. An adhesive dispensing mechanism (obscured in the figure) is located above the adhesive roller 4. The operator places the single-layer PU fabric 2 on the rear of the top wall of the base 1 and pushes it forward until it contacts the feeding roller 3. The feeding roller 3 rotates around its own horizontal axis, thus moving the single-layer PU fabric 2 forward until it contacts the bottom of the adhesive roller 4. The adhesive dispensing mechanism then dispenses adhesive onto the adhesive roller 4. The adhesive roller 4 rotates around its own horizontal axis, thus applying adhesive to the single-layer PU fabric 2. The drawback of the existing technology is that when the adhesive roller 4 has just applied adhesive to the front of the single-layer PU fabric 2, the front of the fabric tends to stick to the roller 4 and cannot detach. It is then rolled up by the roller 4, preventing it from moving forward normally. Utility Model Content
[0003] The present invention aims to provide a single-layer fabric roller coating machine for automobile roofs, which prevents the front of the single-layer fabric from being rolled up by the coating roller when it passes through the coating roller to receive adhesive.
[0004] A single-layer fabric roller coating machine for automotive headliners includes a base. Above the base, from back to front, are a feeding roller and a coating roller. Above the coating roller is a dispensing mechanism. The base is for placing the single-layer fabric. The feeding roller rotates around its horizontal axis, moving the single-layer fabric forward to the bottom of the coating roller. The dispensing mechanism dispenses adhesive towards the coating roller, which rotates around its horizontal axis to apply adhesive to the single-layer fabric. Multiple air jet modules are located in front of the coating roller. Each air jet module has air jet holes on its bottom wall. The air jet modules are tilted downwards and backwards so that the air jet holes are aligned with the bottom of the coating roller. The air jets blow the front part of the single-layer fabric off the bottom of the coating roller.
[0005] Furthermore, there are multiple jet modules, arranged side by side horizontally.
[0006] Furthermore, the left and right side walls of the base are each equipped with a front-to-back transverse slide rail, and a slider is movably installed on each of these two slide rails. The right side wall of the left slider is equipped with a gripper extending to the right, and the left side wall of the right slider is equipped with a gripper extending to the left. These two grippers respectively clamp the left and right sides of the glued single-layer fabric.
[0007] Furthermore, it includes a timer, a controller, and a sensor. The sensor is located behind the feed roller to sense when the front of the single-layer fabric arrives at the feed roller. The controller is connected to the timer, the sensor, and the jet module.
[0008] Furthermore, the glue-applying roller, the feeding roller, and the glue-dispensing mechanism are all horizontally oriented.
[0009] Furthermore, the top wall of the base slopes forward and downward, thereby guiding the front part of the single-layer fabric to slide forward.
[0010] Furthermore, it includes a horizontal rotating shaft, on which the jet module is mounted. The jet module is driven by the horizontal rotating shaft to rotate from a jetting state that is angled downwards and backwards to a jetting state that is vertically downwards.
[0011] Furthermore, the jet module includes a heater that heats the air ejected from the jet module.
[0012] The beneficial effects are as follows: the single-layer fabric is driven forward by the feeding roller, and the front part of the single-layer fabric moves forward to the bottom of the coating roller to receive the coating. The moment the front part of the single-layer fabric passes through the bottom of the coating roller, the jet module sprays jets obliquely downward and backward, thereby blowing the front part of the single-layer fabric off the bottom of the coating roller, thus preventing the front part of the single-layer fabric from being rolled up by the coating roller.

[0017] The present invention will be further described in detail below with reference to specific embodiments.
[0018] like Figure 1 and Figure 2As shown, the gluing machine includes a base 1, on which a feeding roller 3 and a coating roller 4 are mounted, both arranged horizontally from back to front. A glue dispensing mechanism 11 is located above the coating roller 4. A horizontal rotating shaft 14 is located in front of the coating roller 4, and multiple air jet modules 7 are mounted on the rotating shaft 14, arranged horizontally side-by-side. Each air jet module 7 has an air jet hole (not shown in the figure) on its bottom wall, and each air jet module 7 is tilted downwards and backwards so that the air jet hole is aligned with the bottom of the coating roller 4. A sensor is mounted behind the feeding roller 3. The gluing machine is equipped with a timer and a controller, which are connected to the timer, sensor, horizontal rotating shaft 14, and air jet modules 7.
[0019] The following details the working process of the gluing machine. The operator places the single-layer fabric 2 on the rear of the top wall of the base 1 and pushes it forward until it contacts the feeding roller 3. The feeding roller 3 then rotates around its horizontal axis, moving the single-layer fabric 2 forward. A sensor detects when the front part 20 of the single-layer fabric arrives at the feeding roller 3 and sends a feeding signal to the controller. The controller then sends a timing signal to the timer, which begins timing. When the timer reaches the preset duration, the front part 20 of the single-layer fabric has just moved to the bottom of the coating roller 4. The coating roller 4 rotates around its horizontal axis, applying glue to the single-layer fabric 2. The timer then sends a timing signal to the controller, which sends an air jet signal to the air jet module 7. The air jet module 7's bottom wall nozzles spray air towards the bottom of the coating roller 4, blowing the front part 20 of the single-layer fabric from the bottom of the coating roller 4 onto the base 1. Then, the jet module 7 is driven by the horizontal rotating shaft 14 to rotate, changing from an oblique downward jetting state to a vertical downward jetting state. The force of the air 6 on the front part 20 of the single-layer fabric gradually increases as the jet module 7 rotates, and the multi-angle blowing 6 ensures that it is blown onto the base 1. The jet module 7 includes a heater, which heats the air 6 emitted by the jet module 7 to prevent the cold air 6 from blowing the glue on the single-layer fabric 2 to solidify. In addition, the top wall of the base 1 is slightly tilted forward and downward, thereby guiding the front part 20 of the single-layer fabric to slide forward under its own weight, making it less likely to be rolled up by the glue roller 4.
[0020] The base 1 has two side walls, left and right, each equipped with a front-to-back transverse slide rail 8. Each of these two slide rails 8 has a slider 9 movably mounted on it. The right side wall of the left slider 9 is equipped with a gripper 10 extending to the right, and the left side wall of the right slider 9 is equipped with a gripper 10 extending to the left. These two grippers 10 respectively clamp the left and right sides of the front part 20 of the glued single-layer fabric, and then move forward along the corresponding slide rail 8 driven by the corresponding slider 9, thereby taking the glued single-layer fabric 2 away from the base 1.
[0021] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
