Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of pipeline production, and relates to a butt joint traction device for PE pipeline production. Background Technique
[0002] PE pipes are produced by an extruder, and the produced pipes are relatively long. A pipe traction machine is needed for traction operations to facilitate subsequent processing operations. When the PE pipe is cooled while being extruded on the production line, if there is no external tensile force on the extruded PE pipe, it is likely to cause bending and deformation. Through the traction of the traction machine, the PE pipe is continuously output from the extruder and shaped.
[0003] The existing traction machine needs to be butt-jointed with the pipe material. Since the just-produced pipe material has no toughness and is prone to breakage during traction, the traction pipe is then heated so that the produced pipe material can adhere to the traction pipe. At the same time, it is necessary to avoid leaving gaps between the traction pipe and the pipe material. The existing butt-joint steps are usually manual butt-joints, but manual butt-joints are prone to scalding, and at the same time, the speed of manual butt-joints is slow and the efficiency is low, which is not conducive to production. Therefore, we propose a butt-joint traction device for PE pipeline production. Summary of the Invention
[0004] The purpose of the present invention is to address the above problems existing in the prior art and propose a butt-joint traction device for PE pipeline production. The technical problem to be solved by this device is: how to safely and quickly butt-joint the traction machine with the PE pipe.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] A butt-joint traction device for PE pipeline production includes a collection box and a clamping assembly. Above the collection box, there is a discharge die fixed. Above the collection box, there is a first support plate and a second support plate fixed. A traction assembly is arranged on the first support plate and the second support plate. A cutting assembly is arranged inside the traction assembly. A top plate is fixed on the first support plate and the second support plate. A pushing assembly is arranged on the top plate. The clamping assembly includes a pressing motor and a clamping box. The clamping box is fixed above the collection box. The clamping box is circular. Inside the clamping box, there are several groove plates fixed. The several groove plates are distributed in a circumferential manner. On the groove plates, there are racks sliding. The end of the rack is fixed with an electric heating plate. The electric heating plate is arc-shaped. Inside the clamping box, there are several gears rotatably arranged. The several gears are all engaged with the corresponding racks. On the several gears, there is an internal gear engaged. The pressing motor is fixed on the side of the clamping box. The output shaft of the pressing motor is connected to one of the gears through a coupling.
[0007] The working principle of the present invention is as follows: The pushing component pushes the traction component to move. The traction component drives the cutting component to move to the discharging die. The discharging die discharges materials. The cutting component cuts the initial pipe material. The cut pipe material falls into the interior of the collection box. The pushing component pushes the traction component to move again. The traction component drives the cutting component to abut against the discharging die. The pipe material produced by the discharging die is sleeved on the cutting component. Then, the traction rope is fixed on the traction component. The traction rope drives the traction component to move in the reverse direction. The traction component drives the cutting component to move into the clamping box. The pressing motor drives one of the gears to rotate through the output shaft. The gear drives the internal gear to rotate. The internal gear drives the remaining gears to rotate. The gears drive the rack to slide inside the groove plate. The rack drives the electric heating plate to abut against the pipe material, thereby extruding and heating the pipe material, making the pipe material adhere to the cutting component, avoiding air leakage, and completing the docking. After that, the traction rope drives the traction component to move in the reverse direction. The traction component drives the cutting component to move to the next device for processing.
[0008] A blanking port is provided above the collection box, and a drawer box is slidably arranged inside the collection box.
[0009] With the above structure, the cut pipe material falls into the interior of the blanking port and then falls into the interior of the drawer box through the blanking port.
[0010] The traction component includes a traction pipe, which is slidably arranged on the first support plate and the second support plate. A number of chuck slots are provided on the outer side of the traction pipe, and spring chucks are arranged inside the chuck slots. One end of the traction pipe is fixed with a fixing plate, and two connecting holes are fixed on the fixing plate.
[0011] With the above structure, the traction rope is connected to the fixing plate through the connecting hole. The traction rope drives the fixing plate to move in the reverse direction. The fixing plate drives the traction pipe to move in the reverse direction.
[0012] The pushing component includes a threaded rod and a pushing motor. The threaded rod is rotatably arranged on the second support plate. A clamping block is threadedly connected to the threaded rod. The clamping block abuts against the top plate. A clamping plate is clamped below the clamping block. The clamping plate abuts against one end of the traction pipe. The pushing motor is fixed on the side of the second support plate, and the output shaft of the pushing motor is connected to the threaded rod through a coupling.
[0013] With the above structure, the clamping plate is clamped on the clamping block. The pushing motor drives the threaded rod to rotate through the output shaft. The threaded rod drives the clamping block to move. The clamping block drives the clamping plate to move. The clamping plate drives the traction pipe to move.
[0014] The cutting assembly includes a first sleeve rod and a connecting pipe. The connecting pipe is fixed to the other end of the traction pipe. A sealing plate is fixed inside the connecting pipe. The first sleeve rod is rotatably arranged on one side of the sealing plate. A spring is arranged inside the first sleeve rod. Two fixed blades are fixed above the first sleeve rod. The angle between the two fixed blades is °. The fixed blades are triangular. An electric push rod is fixed on one side of the sealing plate. An arc-shaped pressing plate is fixed to the end of the electric push rod. A chamfer is arranged inside the arc-shaped pressing plate. An excision motor is fixed on the other side of the sealing plate. The output shaft of the excision motor is connected to the first sleeve rod through a coupling.
[0015] With the above structure, the cut pipe material falls on the first sleeve rod. The electric push rod drives the arc-shaped pressing plate to move. The arc-shaped pressing plate presses the cut pipe material against the fixed blades. The fixed blades and the arc-shaped pressing plate cooperate to cut the pipe material into three sections. The cut pipe material falls into the inside of the blanking port.
[0016] Two symmetric second sleeve rods are fixed to the end of the first sleeve rod. A cutting knife is fixed to the end of the second sleeve rod. A tension spring is arranged inside the second sleeve rod.
[0017] With the above structure, the excision motor drives the first sleeve rod to rotate through the output shaft. The first sleeve rod drives the two second sleeve rods to rotate. The second sleeve rod drives the cutting knife to rotate. As the rotation speed increases, the centrifugal force drives the second sleeve rod to extend outwards. The second sleeve rod drives the tension spring to extend. At the same time, the second sleeve rod drives the cutting knife to move outwards to cut the pipe material from the inside.
