Problems solved by technology
[0002] In the production of PTFE rods, the extrusion speed of the rods is controlled by the extruder, but in actual production, it is found that when the rods are extruded, due to the weight of the rod itself, will cause the bar to sag
In addition, since the basic speed of the extruder cannot be effectively controlled, it is necessary to add a pressure device at the end of the rod to apply pressure to the rod to ensure the uniformity of the rod extrusion, but after adding the pressure device, The axial pulling force of the bar is not enough to allow the bar to pass through the pressing device, so a pulling force is needed to pull the bar to move axially

The invention relates to a clamping and pulling device in production of a polytetrafluoroethylene rod. The device comprises an underframe, a clamping device and a pulling device; the clamping device and the pulling device are respectively arranged on the underframe, and the pulling device is arranged at the rear end of the clamping device. According to the invention, the pressure of a rod clamp can be timely and quickly adjusted by an air cylinder of the clamping device; the rod is dragged and pulled to axially move through a hydraulic cylinder of the pulling device; and the clamping and pulling device has the characteristics of simple structure, convenience in use and stability in operation.
Description
technical field [0001] The invention relates to a clamping and pulling device in the production of polytetrafluoroethylene bars. Background technique [0002] In the production of PTFE rods, the extrusion speed of the rods is controlled by the extruder, but in actual production, it is found that when the rods are extruded, due to the weight of the rods themselves, Will cause the bar to sag. In addition, since the basic speed of the extruder cannot be effectively controlled, it is necessary to add a pressing device at the end of the bar to apply pressure to the bar to ensure the uniformity of the bar extrusion, but after adding the pressing device, The axial tension of the bar is not enough to allow the bar to pass through the pressurizing device, so a traction force is required to pull the bar to move axially. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a clamping and pulling device ...
