It is required to have sufficient rigidity, strength and light weight to achieve rotational motion. Its accuracy plays a vital role in material accuracy.

[0003] The main rollers commonly used in the market today are characterized by high-speed, frequent reciprocating motions. The inertia generated by the operation of the main rollers makes the positioning pins easily damaged, thus causing certain economic losses. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new main roller connection structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new main roller connection structure includes a rotating plate, a pressure sensor is installed on one side of the rotating plate, a plurality of positioning pins are fixedly connected to one side of the rotating plate, a shell is fixedly connected to one side of the rotating plate, and slide grooves are opened on multiple sides of the shell, and a slider is movably connected in the slide groove. A cylinder is fixedly connected to the inner wall of one side of the shell, and one end of the cylinder piston rod is fixedly connected to a conical block. A fixing ring is fixedly connected to the inner wall of one side of the shell, and the fixing ring is sleeved on the outside of the cylinder. A plurality of tension springs are fixedly connected to the outside of the fixing ring, and the bottom end of the slider is fixed to the tension spring.

[0007] As a further solution of the present invention, a avoidance groove is provided inside the conical block, and one end of the cylinder piston rod is located inside the avoidance groove.

[0008] As a further solution of the present invention, the outer side surface of the shell is provided with a curved surface.

[0009] As a further solution of the present invention, one end of the positioning pin is provided with an inclined surface.

[0010] As a further solution of the present invention, a plurality of anti-slip grooves are provided on the surface of the slider.

[0011] As a further solution of the present invention, a plurality of mounting blocks are fixedly connected to the circumferential outer wall of the rotating plate, and mounting holes are provided in the mounting blocks.

[0012] As a further solution of the present invention, the pressure sensor is electrically connected to the cylinder.

[0013] The beneficial effects of the utility model are:

[0014] 1. The use of locating pins and tapered blocks makes the connection between the rotating plate and the main roller more secure, avoiding the use of a single locating pin connection, which causes the inertia generated by the operation of the main roller to make the locating pin easily damaged, thereby increasing the service life of the device.

[0015] 2. The utility model facilitates the staff to quickly connect the rotating plate and the main roller through the positioning pin through the inclined surface, which plays a certain guiding role.

[0016] 3. The anti-slip grooves in the present invention can increase the friction between the slider and the external main roller, making the connection between the slider and the inner wall of the main roller tighter. BRIEF DESCRIPTION OF THE DRAWINGS
