Description

Technical Field

[0001] The utility model belongs to the technical field of spiral tube production, and particularly relates to a spiral tube extrusion device. Background Art

[0002] Spiral pipe is a tubular product made of plastic material through a special spiral forming process. Unlike metal spiral pipes (such as spiral welded pipes), spiral pipes are usually extruded from polyvinyl chloride (PVC), polyethylene (PE) or other types of thermoplastics through an extruder and continuously formed in a spiral mold to form a continuous spiral structure. Plastic spiral pipes are widely used in many fields due to their light weight, corrosion resistance, easy installation, and relatively low cost. The spiral pipe extrusion device is a mechanical device used to manufacture spiral pipes. It usually includes a feeding system, a heating and melting system, a mold (including a spiral sheet column), an extruder head, and a control system. The working principle of this device is to feed plastic particles or other plastic materials into the device, and after heating and melting, they are continuously extruded into a spiral-shaped pipe through a mold with a spiral structure (spiral sheet column) under the action of extrusion force.

[0003] The existing spiral tube extrusion device uses a single-direction crushing unit to crush the plastic particles and then enter the extrusion spiral sheet column for extrusion and extrusion into a spiral tube. The single-direction crushing unit may not be able to effectively deal with plastic particles of different hardness, shape and size, resulting in uneven crushing effect, affecting the subsequent melting and extrusion process. In particular, for larger or harder particles, the single-direction crushing may not be able to fully crush them to the ideal fineness, reducing the efficiency of spiral tube extrusion. Utility Model Content

[0004] In view of this, the utility model aims to provide a spiral tube extrusion device to address the deficiencies of the prior art. The forward and reverse rotation can change the force direction of the material, and perform more effective shearing, impacting and grinding on the plastic particles, which helps to quickly and evenly crush the particles to a suitable particle size, thereby improving the melting and extrusion efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a spiral tube extrusion device, including a frame plate, a heating box is arranged inside the frame plate, a spiral tube extrusion die is arranged at the extrusion extrusion port opened at the left end of the heating box through mounting bolts, two extrusion spiral sheet columns are rotatably arranged inside the heating box, the right ends of the two extrusion spiral sheet columns are respectively provided with pulleys, the two pulleys are connected by a transmission belt, an electric drive unit 1 for driving the rear pulley to rotate is arranged on the right side of the heating box, a crushing feeding mechanism is arranged on the upper end of the heating box, the electric drive unit 1 includes a motor 1 arranged on the right side of the heating box through a mounting frame, the output shaft of the motor 1 is connected to the right end of the pulley on the rear side through a coupling, the crushing feeding mechanism includes a crushing box arranged at the upper end of the heating box, and the crushing box and the heating box are connected. The interior is connected, and a sleeve is provided for internal rotation of the crushing box, and a plurality of crushing knives are evenly distributed on the outer arc surface of the sleeve, and a rotating column is provided for internal rotation of the sleeve, and a rotating frame is provided on the left side of the outer arc surface of the rotating column, and a plurality of crushing pieces are provided on the inner side surface of the rotating frame, and a forward and reverse linkage component is provided on the right side of the frame plate, and the forward and reverse linkage component includes a mounting plate arranged on the right side of the heating box, and a bevel gear is provided for internal rotation of the mounting plate, and a helical gear 1 is provided on the fixed sleeve on the outer arc surface of the sleeve, and a helical gear 2 is provided on the fixed sleeve on the outer arc surface of the rotating column, and the helical gear 1 and the helical gear 2 are both meshed with a bevel gear, and an electric drive unit 2 for driving the bevel gear to rotate is provided on the right side of the mounting plate, and the electric drive unit 2 includes a motor 2 arranged on the right side of the mounting plate, and the output shaft of the motor 2 is connected to the upper end of the bevel gear through a coupling.

[0006] As a further improvement of the present invention, a control panel is arranged on the left side of the front side of the frame plate, and the motor 1, the motor 2 and the heating box are all electrically connected to the control panel.

[0007] As a further improvement of the present invention, a support frame is provided at the lower end of the frame plate, and a plurality of mounting holes are opened inside the support frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by adding the plastic granule raw materials of the spiral tube to be produced into the inside of the crushing box, and then controlling the operation of motor 2, the output shaft rotates to drive the bevel gear to rotate, so that the helical gear 1 on the left side meshing with it rotates forward to drive the crushing knife on the sleeve to rotate and crush the plastic granules. At the same time, the bevel gear rotates, and also drives the helical gear 2 on the right side meshing with it to reverse and drive the rotating column to rotate, so that the crushing pieces on the rotating frame reversely rotate to further crush the plastic granules. The forward and reverse rotation can change the force direction of the material, and perform more effective shearing, impact and grinding on the plastic granules, which helps to quickly and evenly crush the granules to a suitable particle size, and improve the melting and extrusion efficiency.

[0010] Secondly, the crushed plastic particles enter the interior of the heating box, where they are heated and melted. Then, the motor is turned on through the control panel, and the output shaft rotates to drive the extrusion spiral sheet column on the rear pulley to rotate, and then the extrusion spiral sheet column on the front pulley is driven to rotate through the transmission belt. Under the action of the extrusion force, the plastic particles can be quickly and continuously extruded into spiral-shaped pipes through the spiral tube extrusion die.

[0011] Thirdly, the spiral tube extrusion die can be installed by mounting bolts, which makes it easy for personnel to disassemble and replace it with spiral tube extrusion dies of different sizes through tools, making the extrusion device more flexible.

[0012] Fourthly, the extrusion device can be fixed through the mounting holes inside the support frame, making the operation of the extrusion device more stable and avoiding the occurrence of displacement when the extrusion device is in operation. BRIEF DESCRIPTION OF THE DRAWINGS
