Description

Technical Field

[0001] The utility model relates to the technical field of acrylic rod production, in particular to an acrylic rod production traction machine. Background Art

[0002] Acrylic rod is a common transparent plastic material with the advantages of high transparency, high hardness and strong impact resistance. It is usually made of polymethyl methacrylate (PMMA). Its physical and chemical properties enable it to be used in a variety of applications. A traction machine is required to produce acrylic rods.

[0003] At present, when using a traction machine to produce acrylic rods, it is usually necessary to put one end of the acrylic rod into the traction machine for fixing, and then perform the traction operation. However, due to the different diameter specifications of the acrylic rods, when fixing, it is necessary to replace the fixing structure with different diameter specifications, and the operation is relatively cumbersome. Therefore, we propose a traction machine for producing acrylic rods. Utility Model Content

[0011] As a preferred technical solution of the utility model, the connecting structure includes a connecting tube, which is movably connected to the external thread, and the end of the connecting tube away from the body is fixedly connected to the fixed structure. A connecting rod is fixedly installed on the outer surface of the connecting tube, and the connecting rods are arranged in a circular array on the outer surface of the connecting tube. By assembling the connecting structure with the fixed structure onto the outer surface of one end of the body, the connecting rod drives the connecting tube to move on the end face of the connecting groove, and the internal thread groove moves threadably along the outer surface of the external thread until the connecting tube is fixed to the body in a threaded connection manner, so that the fixed structure can be fixed to one end of the body in a threaded connection manner using the connecting structure, and the operation is simple and quick.

[0012] As a preferred technical solution of the utility model, an internal thread groove is provided on the inner cavity end surface of the connecting tube, and the internal thread groove is threadedly connected to the external thread so as to fix the connecting tube to one end of the body in a threaded connection manner.

Both ends of the limiting rod are fixedly connected to the inner side walls of the fixing frame. By starting the cylinder fixed on the fixing frame, the piston rod on the cylinder moves in the inner cavity of the through hole, and the piston rod drives the clamping block to move in the direction of approaching until one end of the acrylic rod is clamped and fixed, and then the machine body is used to perform a traction operation. During this period, the clamping block drives the moving block to slide along the outer surface of the limiting rod, and plays a role of limiting guide. At the same time, the piston rod on the cylinder can be adjusted to drive the clamping block to move to clamp and fix acrylic rods of different diameters, so as to facilitate the fixation of acrylic rods of different diameters without replacing the fixing structure.
