The setting of the flexible clamp can effectively reduce the leakage problem caused by the movement of the pipe mold. The following device is fixedly installed on the frame, and the conveyor is installed below the swing arm mechanism. A proximity switch is installed at the position of the conveyor corresponding to the up and down swing of the swing arm mechanism.

[0025] Two sets of double-axis cylinders are fixedly installed on the inner side wall of the frame column, the two sets of double-axis cylinders are connected through a swing arm shaft, the swing arm shaft runs through the swing arm mechanism, the bottom of the double-axis cylinder is fixedly installed on a limit block, and the limit block is welded and installed on the frame.

[0026] The gripping cylinder on the swing arm mechanism is fixedly installed on the push plate, a rotating cylinder is installed at the bottom of the swing arm mechanism, the rotating cylinder is fixedly installed at the outer side of the turntable, a right-angle limit block is installed at the bottom of the swing arm mechanism near the turntable, and the guide rod is connected to the turntable.

[0027] The following device is composed of a following cylinder, a swing cylinder, a swing arm, a moving seat, and a swing shaft. The following cylinder is fixedly installed on the lower surface of the horizontal plate of the following device, one end of the swing cylinder is connected to the swing arm, and the other end of the swing cylinder is fixedly installed on the moving seat. The swing shaft is fixedly installed in the moving seat, and the swing shaft runs through the swing arm.

[0028] One end of the swing cylinder is connected to the moving seat through an articulated seat, and the other end of the swing cylinder is fixedly mounted on the swing arm through a fisheye joint.

[0029] A sliding block is installed at one end of the moving seat, the sliding block is slidably connected with the slide rail, and the moving seat is connected with the swing shaft through a bearing.

[0030] The swing shaft is bonded and fixed with a flexible material at the outer side away from the movable seat end.

[0031] A rubber plug is placed on the conveyor belt of the conveyor, the rubber plug is fixedly connected to a fixing rod, and the flexible clamp clamps or releases the rubber plug through the fixing rod.

[0032] The working principle of the present invention is as follows: the double-axis cylinder on the frame is used as the driving force, the swing arm shaft is used as the guiding rotation, and the limit block on the frame is used as the limit, which drives the swing arm mechanism to rotate up and down at a certain angle;

[0033] The rotating cylinder on the swing arm mechanism is used as a drive, the turntable on the swing arm mechanism is used as a guide, and the right-angle limit block on the swing arm mechanism is used as a limit, so that it can rotate back and forth 90° downward and toward the end face of the tube mold; the push cylinder on the swing arm mechanism is used as a drive, the guide rod on the swing arm mechanism is used as a guide, and the push plate on the swing arm mechanism moves in a direction perpendicular to the turntable; the clamping cylinders on both sides of the swing arm mechanism are used as a drive, and the flexible chuck on the swing arm mechanism is used as a transmission to realize the loosening and clamping actions of the flexible chuck;

[0034] The following cylinder on the following device is driven, the guide rail is guided, and the slider is moved, driving the moving seat on the following device to move forward and backward toward the end face of the tube mold; the swing cylinder on the following device is driven, the swing shaft on the following device is guided, the articulated seat, fisheye joint, and bearing are connected, driving the swing arm to rotate up and down at a certain angle.

[0035] Initial position:

[0036] The follower cylinder retracts, and the mobile seat is at the rear end. The swing cylinder extends, and the swing arm moves vertically downward;

[0037] The double-axis cylinder extends, and the swing arm mechanism moves downward. The rotating cylinder shrinks, and the turntable moves downward. The push cylinder shrinks, and the push plate retracts. The gripper cylinder shrinks, and the flexible gripper opens.

[0038] Action sequence:

[0039] The conveyor transports the rubber plug. When the proximity switch on the conveyor detects that the rubber plug is in place, the conveyor stops transporting and waits for the equipment to take the rubber plug.

[0040] The push cylinder extends, and the push plate sticks to the end face of the rubber plug. The clamping cylinder clamps the fixed rod on the rubber plug, the push cylinder contracts, the push plate retracts, the rotating cylinder extends, and the turntable rotates 90° to the end face of the tube mold;

[0041] Wait for the photoelectric switch on the follower device to detect whether the tube mold moves to the working distance of the swing arm. When the distance is reached, the swing cylinder shrinks and the swing arm rotates upward to the limit position (i.e. the center hole position of the tube mold). The follower cylinder extends to block the flexible material on the swing arm toward the center hole of the tube mold. Blocking the flexible material first can effectively reduce the leakage problem caused by the tube mold during movement;

[0042] Since the tube mold is always in motion during the process of plugging, the follower cylinder will also move a distance with the tube mold. Until the photoelectric switch detects that the tube mold has moved to the working range of the swing arm mechanism, the follower cylinder shrinks a short distance to protect the flexible material from rubbing against the end face of the tube mold, the swing cylinder extends, and the swing arm rotates downward to avoid the operation of the swing arm mechanism;

[0043] The double-axis cylinder contracts, the swing arm shaft rotates, and drives the swing arm mechanism to rotate upward. Until the double-axis cylinder hits the mechanical limit on the frame (i.e., the center of the tube mold). The push cylinder extends, drives the push plate to move toward the end face of the tube mold, and pushes the rubber plug on the push plate into the center hole of the tube mold. The clamp cylinder contracts, the flexible chuck opens, and the fixing rod on the rubber plug is released. In order to ensure that the rubber plug can be better inserted into the center hole of the tube mold, a high-speed reversing valve is used to allow the push cylinder to quickly knock the rubber plug over a short distance. After knocking, the push cylinder contracts, the push plate retracts, the rotating cylinder contracts, and the turntable rotates 90° toward the underground direction. The double-axis cylinder extends, and the swing arm mechanism returns to its initial vertical downward state. Reciprocating cycle.

[0044] The above actions are all synchronized with the movement of the tube mold.

[0045] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
