Description

Technical Field

[0001] The present application relates to the technical field of glue coating equipment, and in particular to an easy-to-clean glue spray head for glue spraying equipment. Background Art

[0002] Conventional glue coating equipment mostly uses a structure that stores glue on one side and a valve controlled by a controller on the other side. The stored glue is released by opening the valve, and then flows out or sprays out through the glue outlet to complete the gluing. The stored glue needs to pass through a long and narrow channel before entering the valve. Since the internal diameter of the long and narrow channel is small, it is relatively inconvenient to transport the glue in it, and it is easy to form residue. Glue coating equipment is mostly used in special fields, such as aerospace, automobile manufacturing, electronic manufacturing, etc. Therefore, the quality control of the glue is very strict. Therefore, the long and narrow channel here needs to be disassembled frequently, and the inner cavity of the long and narrow channel needs to be cleaned to ensure the quality of the glue.

[0003] like Figure 5 As shown, glue is mostly stored in the first delivery pipe 4, and the second delivery pipe 5 enters the glue outlet 6. The second delivery pipe 5 here is the slender channel mentioned above. The second delivery pipe 5 needs to be disassembled and cleaned regularly, and the operation is relatively complicated. Utility Model Content

[0004] The present application provides an easy-to-clean glue spray head for glue spraying equipment, which improves the existing glue coating nozzle, adjusts the glue outlet to below the first conveying pipe, eliminates the second conveying pipe and the glue outlet structure, and converts the glue outlet into a glue outlet pipe, a connecting pipe and a glue head cover, eliminating the need for cleaning of the slender channel, thereby greatly simplifying the daily cleaning and maintenance of the glue spray equipment nozzle.

[0005] The present application provides an easy-to-clean glue spray head for glue spraying equipment, which adopts the following technical solution:

[0006] A glue spray head of glue spraying equipment that is easy to clean comprises a glue head cover and a glue outlet pipe. A connecting pipe is arranged between the glue head cover and the glue outlet pipe. The connecting pipe is arranged as a hollow circular pipe and comprises a pipe hole.

[0007] By adopting the above technical scheme, through the arrangement of the glue outlet pipe, the connecting pipe and the glue head cover, the second conveying pipeline and the glue outlet structure can be replaced, eliminating the need for cleaning of the slender channel, thereby achieving the technical effect of simplifying the daily cleaning and maintenance of the nozzle of the glue spraying equipment.

[0008] In a specific possible implementation scheme, the rubber head cover is configured to be conical, and a circular hole is opened on the top of the rubber head cover to form a glue outlet, and the glue outlet is connected to the tube hole.

[0009] By adopting the above technical solution, by setting the shape of the glue head cover to a cone, the glue head cover can be easily adapted to move in small gaps, making it easier to apply glue to narrow areas. The glue outlet is set as an open circular hole, and the downward opening setting can prevent glue from being retained near the glue outlet during glue discharge, causing blockage in the glue outlet.

[0010] In a specific possible implementation manner, a first thread and a second thread are formed on the outer surface of the connecting pipe, and the pitches of the first thread and the second thread are different.

[0011] By adopting the above technical solution, the pitches of the first thread and the second thread are different, so that different threads can only match their corresponding pitches, which can prevent the connecting pipe from being screwed into one side excessively. This setting can make the rubber head cover and the rubber outlet pipe each screwed in half.

[0012] In a specific possible implementation mode, a circular groove is formed on the rubber head cover to form a first groove, and a first groove thread matching with the first thread is formed in the first groove.

[0013] By adopting the above technical solution, the first groove thread is configured as an inner groove thread opened in the first groove. When threadedly matched with the connecting pipe, the setting of the inner groove thread can play a role of sealing and leakage prevention. The setting of the inner groove thread allows the connecting pipe to be inserted into the first groove when the threads are matched, which can protect the connecting pipe.

[0014] In a specific possible implementation manner, the glue outlet pipe comprises a glue outlet end and a glue outlet pipe body, and the glue outlet end is a curved protrusion integrally provided on the glue outlet pipe body.

[0015] By adopting the above technical solution and setting the glue outlet end as a curved protrusion, the stress when the glue outlet end contacts other parts of the equipment can be reduced, and the probability of damage due to collision can be reduced.

[0016] In a specific possible implementation scheme, a ring is convexly arranged on the glue outlet end and a second groove is formed inside the ring, and a second groove thread is provided in the second groove.

[0017] By adopting the above technical solution, the second groove thread cooperates with the second thread to play a role in installing the connecting pipe.

[0018] In a specific possible implementation manner, a glue channel for glue discharge is provided at the bottom of the first groove.

[0019] By adopting the above technical solution, the glue channel is used to transport the glue.

[0020] In a specific possible implementation scheme, a plurality of rectangular grooves are provided on the surface of the rubber head cover to form positioning notches, and the positioning notches are distributed in a ring shape.

[0021] By adopting the above technical solution, when the product is installed on the glue spraying equipment, the positioning notch can more accurately locate the position of the glue head cover, thereby improving the glue coating accuracy.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the glue head cover and the glue outlet pipe, a connecting pipe is arranged between the glue head cover and the glue outlet pipe. By arranging the glue outlet pipe, the connecting pipe and the glue head cover, the second conveying pipeline and the glue outlet and other structures can be replaced, eliminating the need for cleaning of the slender channel, thereby achieving the technical effect of simplifying the daily cleaning and maintenance of the nozzle of the glue spraying equipment.

[0024] 2. By setting the pitch of the first thread and the second thread to be different, it is possible to prevent the connecting pipe from being screwed into one side excessively when the first groove thread and the second groove thread are installed, thereby playing a positioning role. This setting enables the rubber head cover and the rubber outlet pipe to be screwed in half respectively, and the connecting pipe remains centered between the rubber head cover and the rubber outlet pipe.
