[0002] Glue filling machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue dispensing machine, etc., is an automated machine that specializes in controlling fluids and dripping and applying fluids to the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no glue leakage, and no glue dripping. Glue dispensing machines are mainly used for the precise dot, injection, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dotting, drawing lines, circles or arcs.

[0003] The method used by ordinary fixed needles facing the circular dispensing track is generally that CNC drives the dispensing valve to make circular motion.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3The present invention provides a technical solution: a two-component rotary valve, comprising a valve body 1, wherein a small motor 2 is arranged inside the valve body 1, wherein the output end of the small motor 2 is fixedly connected to the top of a rotating shaft 11, and the small motor 2 is coupled to an external control panel. The small motor 2 is the power for the rotating shaft 11 to rotate, driving the glue discharge needle 10 to rotate, and can inject glue into the inner wall of the circular ring structure.

[0021] An adapter plate 3 is fixedly connected to the upper surface of the valve body 1, and a glue pipe 4 is opened inside the adapter plate 3. The liquid inlet end of the glue pipe 4 is connected to the glue valve, and the other end of the glue valve is connected to the required glue. The liquid outlet end of the glue pipe 4 extends out of the side wall of the adapter plate 3 and is fixedly connected to a connecting valve 5. The bottom end of the connecting valve 5 is fixedly connected to a material pipe 6, and the liquid outlet end of the material pipe 6 is fixedly connected to a connecting pipe 7 extending to the inside of the valve body 1. The connecting valve 5 and the connecting pipe 7 are connected to one end of the material pipe 7. The joint structure of the ferrule type is a ferrule type. The ferrule type pipe joint consists of three parts, a joint body, a ferrule and a nut. After the ferrule and the nut are sleeved on the material pipe 6 and inserted into the joint body, when the nut is tightened, the outer side of the front end of the ferrule fits with the conical surface of the joint body, and the inner edge bites evenly. The seamless material pipe is inserted to form an effective seal to prevent glue leakage. The liquid outlet end of the connecting pipe 7 is provided with a circular channel 8 adapted thereto. The circular channel 8 surrounds the rotating shaft 11 for one week. The main purpose is to prevent the glue from being affected by the rotation when the rotating shaft 11 rotates, and to continue to provide glue to the glue discharge needle 10. The number of glue pipelines 4, connecting valves 5, material pipes 6, connecting pipes 7 and circular channel 8 is two, which are divided into two groups. Different types of glue can be placed in the two groups. The circular channel 8 is not at the same horizontal position to prevent the two groups of glue from mixing and causing unnecessary waste. When it is large-scale, the type of glue discharge can be switched by controlling the rotary valve, which achieves fast switching and saves a lot of switching time, reduces production costs, and improves work efficiency.

[0022] The liquid outlet end of the annular channel 8 is connected to the glue discharge needle 10 through the rubber hose 9. The glue discharge needle 10 is designed to be bent. When the glue discharge needle 10 is bent, in order to better penetrate into the corner of the annular ring for glue injection, the glue discharge needle 10 can be rotated. By rotating the glue discharge needle 10, glue can be injected into the corners of each cylinder. The rubber hose 9 can be disassembled through the external hexagonal nut. The disassembly of the rubber hose 9 can be convenient and quick for cleaning, and rubber hoses of different specifications can also be replaced.

[0023] The bottom end of the valve body 1 is rotatably connected to a rotating shaft 11, the upper end of the rotating shaft 11 extends to the interior of the valve body 1, and a rotating sleeve 12 is provided between the outer wall of the rotating shaft 11 and the inner wall of the valve body 1. The rotating sleeve 12 is mainly used to prevent the rotating shaft 11 from rubbing against the inner wall of the valve body 1 during rotation, causing damage and affecting the accuracy and work efficiency of glue injection. The two-component glue remains independent of each other and does not contact each other in the rotating structure, thereby preventing the glue from solidifying and crystallizing in the rotating structure. A sealing ring 13 is provided between the rotating shaft 11 and the rotating sleeve 12 to prevent the two-component glue from meeting. The sealing ring 13 is made of rubber. The sealing ring 13 is mainly used to prevent the two groups of glue from meeting each other to prevent waste in production.

[0024] Working principle: When large-scale annular parts need to be injected with glue, the required glue is allowed to flow in from the glue pipe 4 by rotating the valve, and the glue passes through the connecting valve 5, the material pipe 6, the connecting pipe 7, the circular channel 8 and the rubber hose 9 to reach the glue needle 10. The user controls the cooperation between the glue filling machine and the rotating shaft 11 to align the glue needle 10 with the required injection position. Since the glue needle 10 is a bent shape, it can be deeply injected into the corner of the circular ring, and the inner wall of the circular ring can also be fully filled for a single or multiple hole positions, thereby achieving the effect of improving technical production capacity. When different glues are needed, another glue can be switched by rotating the valve, and the parts can continue to be injected with glue in the same working mode, thereby saving time, reducing production costs, and improving work efficiency. When the machine is not in use, the rubber hose 9 can be disassembled for cleaning and maintenance, thereby reducing waste of resources.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
