Description

Technical Field

[0001] The utility model relates to the technical field of air duct manufacturing, in particular to a metal belt traction device for a stainless steel ventilation pipe. Background Art

[0002] Spiral duct is a thin-walled spiral tube made of metal strips. It is round and is mostly used for air supply and bulk material transportation, replacing traditional galvanized iron pipes. Its main uses are as follows:

[0003] (1) Air supply, including ventilation, such as fresh air supply and exhaust air supply, has a wide range, such as factory workshops and production sites. Because harmful gases need to be discharged outdoors, outdoor air needs to be transported indoors. At this time, air delivery pipes with large flow and low pressure should be used. Spiral air ducts are the most suitable. Galvanized iron pipes are generally used, and stainless steel pipes are used in corrosive and particularly humid places.

[0004] (2) Exhaust oil smoke. The kitchens of restaurants, hotels and inns all produce a lot of oil smoke, which needs to be exhausted. The circular air duct is the oil smoke chimney. Here, the spiral air duct should be called the oil smoke duct.

[0005] Patent application number 2009100314686 discloses a main machine for a spiral duct forming machine. When the forming wheel box pulls the metal strip, as the metal strip is consumed, the thickness of the metal strip gradually decreases, and the metal strip gradually moves downward, which is prone to contact and friction with the frame, affecting the flatness of the metal strip surface. Utility Model Content

[0006] The utility model aims to provide a metal belt traction device for a stainless steel ventilation pipe, which has the effect of protecting the metal belt.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a metal belt traction device for a stainless steel ventilation pipe, comprising a frame and a metal belt roller rotatably connected to the frame, characterized in that: a forming roller group and a traction roller group are connected to the frame, the forming roller group comprises a plurality of forming rollers rotatably connected to the frame, a feed end and a discharge end are provided on the forming roller group, the traction roller group is arranged at the discharge end, a support roller located at the feed end is rotatably connected to the frame, a lubricating oil sponge located at the bottom of the support roller is fixedly connected to the frame, and the lubricating oil sponge is in contact with the bottom surface of the support roller.

When the traction device is used, the metal belt passes through the top of the support roller and extends into the forming roller group. The metal belt extending out of the forming roller group is pulled by the traction roller group so that the metal belt continues to pass through the forming roller group. As the metal belt on the metal belt roller is consumed, the metal belt extending into the forming roller group gradually deviates downward and contacts the top of the support roller. The support roller reduces the friction with the bottom surface of the metal belt. At the same time, the lubricating oil sponge oils the outer surface of the rotating support roller to further reduce the friction between the support roller and the metal roller.

[0013] The utility model is further configured as follows: the traction roller group comprises two driving rollers rotatably connected to the frame, the rotation axes of the two driving rollers are parallel to each other and located in the same vertical plane, and the outer wall of the driving roller is covered with an anti-slip sleeve.

[0014] By adopting the above technical solution, the metal belt passes between the two driving rollers, and the rotating driving rollers exert driving force on the two end surfaces of the metal belt along the tangential direction of the anti-slip sleeve to achieve traction on the metal belt.

[0015] The utility model is further configured as follows: the anti-slip sleeve is provided with anti-slip grooves.

[0016] By adopting the above technical solution, anti-skid patterns are provided on the anti-skid sleeve, so as to increase the static friction between the metal belt and the anti-skid sleeve, thereby improving the driving stability of the metal belt.

[0017] The utility model is further configured as follows: a mounting plate is slidably connected in the sponge groove, the lubricating oil sponge is fixedly connected to the mounting plate, and a pushing spring is arranged between the mounting plate and the sponge groove.

[0018] By adopting the above technical solution, the push spring applies an upward thrust to the lubricating oil sponge through the mounting plate so that the lubricating oil sponge extends out of the connecting port and maintains stable contact with the bottom of the supporting roller.

[0019] The utility model is further configured as follows: an oil absorption convex portion is provided at the bottom of the lubricating oil sponge, an oil absorption hole for the oil absorption convex portion to pass through is provided on the mounting plate, and the oil absorption convex portion passes through the oil absorption hole and contacts the bottom surface of the sponge groove.

[0020] By adopting the above technical solution, the oil absorption convex part passes through the oil absorption hole and contacts the bottom surface of the sponge groove, thereby absorbing the lubricating oil accumulated at the bottom of the sponge groove.

[0021] The utility model is further configured as follows: the side wall of the connection port is threadedly connected with a limit screw, and the limit screw extends out of the side wall of the connection port to limit the mounting plate from being separated from the connection port.

[0022] By adopting the above technical solution, the limit screw extends out of the side wall of the connection port to limit the mounting plate from being separated from the connection port, thereby improving the stability of the mounting plate setting.

[0023] The utility model is further configured as follows: an oil drain pipe is provided at the bottom of the sponge groove, and an oil drain valve is connected to the oil drain pipe.

[0024] By adopting the above technical solution, the oil drain valve is opened to discharge the excess lubricating oil in the sponge groove.

[0025] The beneficial effects of the utility model are:

[0026] 1. Rotate the connecting support roller at the feed end, and the metal belt gradually deviates downward to contact the top of the support roller. The support roller with lubricating oil reduces the friction with the bottom surface of the metal belt, thus protecting the metal belt;
