Description

Technical Field

[0001] The utility model relates to a glue spraying technology, in particular to a glue spraying device for the inner wall of a tire. Background Art

[0002] Spraying glue on the inner wall of a tire is a technology aimed at enhancing the air leakage prevention and puncture resistance of the tire by applying a special glue or polymer composite material on the inner wall of the tire. This technology is usually called selfseal or puncture resistant tire technology, and its principle is to coat a gel-like glue or polymer composite material on the inner wall of the tire to form an airtight layer. When the tire encounters a sharp object piercing, this layer of material can quickly repair the perforation, thus ensuring that the tire does not leak air and guaranteeing the safe driving of the vehicle;

[0003] The existing glue spraying method generally uses a mechanical hand to hold a glue gun for spraying. However, the mechanical hand itself has a high cost and occupies a large space. It is not only difficult to be applicable to positions with a small space, but also has high requirements for the use environment. Content of the Utility Model

[0023] Embodiment 1:

[0024] As Figure 1 As shown in Fig. -3, a device for spraying glue on the inner wall of a tire includes a bracket 1. A rubber hose 3 is provided on one side of the bracket 1. A driving unit, a connecting rod 9 and a hinge bracket 6 are provided on the other side of the bracket 1. The driving unit and the hinge bracket 6 are respectively fixed at both ends of the bracket 1. An installation block 7 is hinged to one end of the bracket 1 relative to the hinge bracket 6. A glue gun 8 is installed on the installation block 7. The glue gun 8 is communicated with the rubber hose 3. The connecting rod 9 is arranged between the driving unit and the hinge bracket 6. The connecting rod 9 is hinged to the installation block 7. The driving unit drives the installation block 7 to rotate around the hinge bracket 6 through the connecting rod 9. The driving unit includes a glue gun swing motor 4 and a connecting frame 10. The glue gun swing motor 4 is fixed at one end of the bracket 1 relative to the hinge bracket 6. The glue gun swing motor 4 drives the connecting frame 10 to move. One end of the connecting rod 9 relative to the installation block 7 is hinged to the connecting frame 10.

[0025] The tire inner wall glue spraying device of this embodiment adopts a driving unit, a connecting rod 9 and a mounting block 7, which can realize the swinging of the glue gun 8. It has a simple structure, occupies less space, sprays glue evenly, adapts to the inner wall structure of the tire with a middle plane and two side arc surfaces, has strong adaptability and good glue spraying effect.

[0026] Among them, the glue gun swinging motor 4 is a linear motor, which can also be replaced by a cylinder or an electric cylinder; the driving unit can also be a motor and a lead screw driven by the motor to rotate. The connecting frame 10 is sleeved on the lead screw and is in threaded cooperation with the lead screw; and a position sensor can be set at the position of the connecting frame 10 during the flat glue spraying position to adapt to relatively long flat glue coating and ensure that the connecting frame 10 does not move during flat glue coating.

[0027] An installation frame 2 is provided on the bracket 1. The installation frame 2 is used to install the bracket 1 on an external device. The external device is mainly a translation structure to realize the translation of the bracket 1; a protective plate 5 is provided on the outside of the connecting frame 10, and the protective plate 5 is fixed to the bracket 1; moreover, the glue gun swinging motor 4 and the installation frame 2 are respectively located on both sides of the protective plate 5. The protective plate 5 and the bracket 1 can protect the periphery of the connecting frame 10 to prevent foreign objects from entering.

[0028] Blocks are provided on both sides of the connecting frame 10; the setting of the blocks can prevent the connecting frame 10 from moving excessively, resulting in the glue gun 8 swinging excessively and hitting the tire side wall, playing a role in protecting the glue gun 8.

[0029] Limit strips are provided on both sides of the rubber hose 3. The limit strips are abutted against the rubber hose 3 and fixed to the top or bottom of one side of the bracket 1. The limit strips are used to support and limit the rubber hose 3 on the bracket 1.

[0030] Working principle: Start spraying glue from the arc surface on one side of the tire inner wall. The tire rotates at a constant speed. At this time, the glue gun swinging motor 4 drives the connecting frame 10 to move closer to or away from the side of the glue gun swinging motor 4. At this time, the connecting rod 9 drives the installation frame 2 to rotate around the hinge frame 6, so that the glue gun 8 faces the arc surface. As the angle of the arc surface changes, the glue gun swinging motor 4 drives the connecting frame 10 to move to the other side. When entering the flat glue spraying, the glue gun swinging motor 4 stops working, and the external translation structure drives the bracket 1 to translate, so that the glue gun 8 simultaneously translates to spray the flat surface of the tire inner wall. When entering the arc surface glue spraying on the other side, the glue gun swinging motor 4 drives the connecting frame 10 to continue moving to the other side. At this time, the glue gun 8 swings to the other side to realize the spraying of the arc surface.

[0031] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention all fall within the scope of the technical solution of the present invention.
