Description

Technical Field

[0001] This utility model relates to the field of automated production equipment for functional pipe fittings, specifically to a device for applying adhesive to pipe end caps. Background Technology

[0002] A functional pipe fitting is needed, comprising: a straight pipe, one end of which needs to be fitted with an end cap. Before assembly, a ring of glue needs to be applied to the inner wall of the end cap. After assembly, the glue will fix the end cap to the end of the straight pipe. The glue in the end cap is usually applied by a worker using a hand-held glue gun. Manual glue application has disadvantages such as low processing efficiency, high labor costs, and inconsistent glue application quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pipe end cap glue applicator that can automatically apply glue to the end caps.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a pipe end cap glue applicator, comprising: a worktable, characterized in that: a base plate capable of sliding left and right is provided on the worktable, and a base plate driving mechanism for driving the base plate to move left and right is provided on the base plate; a T-shaped plate is provided above the base plate, the T-shaped plate is inverted, and the horizontal plate of the T-shaped plate is fixed to the base plate by bolts; a lifting frame capable of sliding up and down is installed on one side of the vertical plate of the T-shaped plate; a vertical glue cylinder containing glue and a pneumatic dispensing valve oriented left and right are installed on the lifting frame; the upper port of the glue cylinder is used to connect to an air source, and the lower port of the glue cylinder is connected to the glue inlet of the dispensing valve; a horizontally arranged glue applicator tube is connected to the glue outlet of the dispensing valve. The front end bends downwards, causing the glue outlet of the dispensing tube to face downwards. A cylinder seat is fixed on the other side of the vertical plate of the T-shaped plate, and a lifting cylinder is installed on the cylinder seat. A connecting plate is set between the lifting cylinder and the lifting frame. One end of the connecting plate is fixed to the lifting cylinder, and the other end of the connecting plate is fixed to the lifting frame, so that the lifting cylinder can drive the lifting frame to rise and fall. After the base plate moves inwards under the drive of the base plate drive mechanism, the glue dispensing tube on the dispensing valve can be inserted into the end cap. Then, after the lifting frame descends under the drive of the lifting cylinder, the front end of the glue dispensing tube can approach the inner wall of the end cap, so that the glue dispensed after the dispensing valve is activated can fall onto the inner wall of the end cap. Thus, after the end cap is driven to rotate, a ring of glue can be applied to the inner wall of the end cap.

[0005] Furthermore, in the aforementioned pipe end cap glue application device, a glue receiving box for catching waste glue is fixed on the horizontal plate of the T-shaped plate below the glue dispensing valve.

The tail end of the air jet connector is connected to an air source, and the front end of the air jet connector is connected to an air jet pipe. The air jet pipe is bent so that it can be inserted into the end cap in parallel with the glue application pipe. The outlet of the air jet pipe is facing the glue outlet of the glue application pipe. After the air jet connector is vented, the air jet pipe can spray air at the glue outlet, so that the glue line generated when the glue outlet leaves the end cap can be blown off.

[0007] Furthermore, in the aforementioned pipe end cap glue application device, the lifting frame is composed of two parts joined together front and back, the glue cylinder is sandwiched between the two parts of the lifting frame, and a long strip-shaped through hole is provided on the outer wall of the lifting frame for observing the amount of glue in the glue cylinder.

An end cap glue application finger and a glue application rotation mechanism for driving the end cap glue application finger to rotate are installed on the mounting base. The end cap glue application finger is located inside the glue dispensing valve. The end cap glue application finger can grasp the end cap. After the glue dispensing valve moves inward, the glue application tube can be inserted into the end cap. After the end cap glue application finger rotates 360 degrees with the end cap under the drive of the glue application rotation mechanism, the glue application tube can apply a ring of glue to the inner wall of the end cap.

[0010] Furthermore, in the aforementioned pipe end cap glue application device, the glue application rotation mechanism has the following structure: a horizontally arranged, rotatable drive shaft and a servo motor are mounted on the mounting base; the end cap glue application finger is fixed to one end of the drive shaft; and synchronous pulleys are fixed to the output shaft of the servo motor and the other end of the drive shaft; the servo motor and the drive shaft are driven by a synchronous belt.
