Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery and equipment, and particularly relates to a simple and reliable tube-gripping device. Background Art

[0002] As one of the most important industries in the world, with the development of economy and technology, more textiles are produced and consumed in the world than ever before. Among them, yarn is an important kind of textile raw material. In order to facilitate storage, transportation and subsequent processing, it needs to be wound around a paper tube according to a certain length and weight, and at the same time, the yarn can be ensured to have a certain and uniform tension.

[0003] However, the installation of paper tubes is still mainly manual at present, with low work efficiency; and the existing tube-gripping devices not only have a relatively complex structure, high manufacturing cost, but also the paper tubes are prone to fall off. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a simple and reliable tube-gripping device, hoping to make up for the deficiencies of the existing technology and solve all or part of the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A simple and reliable tube-gripping device is composed of a clamping mechanism, a positioning mechanism and a swing arm mechanism;

[0007] The swing arm mechanism includes a swing arm, a swing arm mounting seat, a cylinder, a connecting plate and a cylinder mounting seat. The swing arm is fixed to the swing arm mounting seat at its tail end, the swing arm mounting seat is mounted on a supporting rotating shaft of an external device, the connecting plate is fixed to the swing arm, the moving end of the cylinder is movably connected to the connecting plate, and the tail end of the cylinder is movably connected to the cylinder mounting seat;

[0008] The positioning mechanism includes a proximity switch and a positioning bolt. The positioning bolt is fixed to the swing arm, the proximity switch is fixed to the frame of the external device, and the positions of the proximity switch and the positioning bolt are matched;

[0009] The clamping mechanism includes pneumatic fingers, a pneumatic finger mounting bracket, a left clamping plate and a right clamping plate. The pneumatic finger mounting bracket is fixed to the head end of the swing arm, the pneumatic fingers are fixed to the pneumatic finger mounting bracket, the left clamping plate and the right clamping plate are symmetrically arranged and are respectively connected to the moving ends of the pneumatic fingers. Particularly, the pneumatic fingers are cylinder action components with two moving ends moving towards each other.

[0010] This solution is connected to the cylinder through a connecting plate, converting the linear motion of the cylinder into the rotational motion of the swing arm. As the swing arm rotates, the positioning bolt approaches the proximity switch. At this time, the pneumatic finger works to tightly clamp the paper tube. Subsequently, the swing arm continues to rotate to the specified position, the pneumatic finger releases the paper tube, and the swing arm resets. The structure is simple, the efficiency is high, and the clamping is reliable.

[0011] In an implementation manner that can optimize the foregoing solution, the swing arm is an angle-shaped sheet metal part. The angle-shaped swing arm can further improve the strength of the swing arm, and at the same time facilitate the connection of other structures to the swing arm, making the installation and disassembly convenient.

[0012] In an implementation manner that can optimize the foregoing solution, the pneumatic finger mounting bracket is of a U-shaped structure, with an installation slot opened on one side. It is fixedly connected to the swing arm through the installation slot, and the installation position can be adjusted through the installation slot. The top and one side of the pneumatic finger mounting bracket are respectively provided with installation bolt holes, and the pneumatic finger is fixed on the pneumatic finger mounting bracket through the installation bolt holes at the top and on one side. The clamping force is adjusted by adjusting the air pressure, so as to clamp paper tubes with different material hardnesses.

[0013] In an implementation manner that can optimize the foregoing solution, both the left clamping plate and the right clamping plate are horizontally arranged V-shaped structures. The V-shaped clamping plate can not only clamp paper tubes of different sizes, but also prevent the paper tubes from accidentally falling off.

[0014] In an implementation manner that can optimize the foregoing solution, when the tube-gripping device grabs, the minimum distance between the left clamping plate and the right clamping plate is not greater than 60 mm. It can clamp paper tubes with diameters ranging from 60 mm to the maximum opening size of the clamping plate.

[0015] In an implementation manner that can optimize the foregoing solution, it further includes small shaft A and small shaft B. The tail end of the cylinder is movably connected to the cylinder mounting seat through small shaft A, and the operating end of the cylinder is movably connected to the connecting plate through small shaft B.

[0016] In an implementation manner that can optimize the foregoing solution, the connecting plate is fixed at the rear end of the swing arm, close to the position of the swing arm mounting seat.
