[0019] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.
[0020] See also Figure 1-6 ,
[0021] A water pipe manufacturing device includes an extrusion head 101, in which a forming column 102 is welded, two connection covers 301, each of which has a guide groove 302, and each of which is fixedly connected to a connecting pipe 303, and a traction column 401, which is connected to a traction mechanism.
[0022] When using the manufacturing device, the staff first fixes the extrusion head 101 in the screw extruder with bolts, heats the plastic particles to a molten state and extrude them through the screw extruder, and when passing through the extrusion head 101, the molten plastic is extruded in a tubular shape with the cooperation of the extrusion head 101 and the molding column 102.
[0023] The molding column 102 is used to install the traction tube, which is a finished plastic tube used to be integrated with the extruded molten plastic, so as to facilitate the traction of the plastic molding. When the plastic is about to be extruded, the staff installs the traction tube on the traction column 401, and the traction column 401 moves close to the molding column 102. When the plastic is extruded, it can wrap the traction tube on the traction column 401. The extruded plastic uses the residual heat to heat the traction tube, so as to be integrated with the traction tube. At this time, by controlling the two connecting covers 301 to buckle with each other, the extrusion force generated by the two connecting covers 301 is used to extrude the plastic and the traction tube, thereby promoting the integration of the plastic and the traction tube, increasing stability, and avoiding breakage during the traction process.
[0024] The two connecting pipes 303 are used to connect to the container filled with cold water. The cold water is transmitted to the connecting cover 301 through the connecting pipes 303. When the two connecting covers 301 squeeze the plastic and the traction tube, the cold water can diffuse outward through the guide groove 302 in the connecting cover 301, thereby cooling and shaping the plastic and the traction tube, hardening the connection between the plastic and the traction tube, and facilitating the subsequent traction process. The cold water is evenly diffused through the guide groove 302, thereby achieving a comprehensive cooling effect.
[0025] The device can realize automatic connection between plastic and traction tube without manual connection, thereby improving production efficiency and avoiding burns to workers caused by manual connection, further reducing the labor intensity of workers.
[0026] See also Figure 1-3 ,
[0027] The manufacturing device also includes a mounting frame 201 , on which two slide bars 202 are welded, two connecting covers 301 are slidably connected to the two slide bars 202 , and springs 203 are fixedly connected between the two connecting covers 301 and the mounting frame 201 .
[0028] The mounting frame 201 is fixed on other building objects. When the plastic and the traction tube need to be connected, the staff controls the two connecting covers 301 to slide relative to each other on the two sliding rods 202, and the two springs 203 are stretched at the same time. When the plastic and the traction tube are connected, the two connecting covers 301 are released, and the two connecting covers 301 are automatically reset and opened under the action of the springs 203.
[0029] See also Figure 5-6 ,
[0030] The traction column 401 is rotatably connected to two rotating rods 402 via an axis, and contact rods 403 are welded to the ends of the two rotating rods 402 . The two connecting covers 301 are fixedly connected to a triangular plate 304 .
[0031] When the traction column 401 moves close to the forming column 102, the two contact rods 403 respectively contact the two triangular plates 304, so that the two connecting covers 301 can be synchronously moved relative to each other, thereby realizing the function of simultaneously controlling the two connecting covers 301. When the traction column 401 moves backward and starts to pull the plastic, the two contact rods 403 respectively detach from the two triangular plates 304, and then the two connecting covers 301 can be reset under the action of the spring 203.
[0032] See also Figure 8 ,
[0033] Torsion springs are installed at the rotational connection points between the two rotating rods 402 and the traction column 401 . The traction column 401 is fixedly connected with two right-angle plates 404 , which are in contact with the two rotating rods 402 respectively.
[0034] The two rotating rods 402 are in an automatically opened state under the action of the torsion spring, and the opening angles of the two rotating rods 402 are fixed under the limiting action of the right-angle plate 404 .
[0035] See also Figure 7 ,
[0036] The manufacturing device also includes a vacuum tube 501, and the traction column 401 passes through the vacuum tube 501. The traction column 401 is coaxial with the vacuum tube 501. When the traction column 401 moves backward and starts to pull the plastic, the two rotating rods 402 both contact the inner wall of the vacuum tube 501, thereby causing the two rotating rods 402 to rotate and contract at the same time, and the torsion spring is in a stressed state.
[0037] See also Figure 7 ,
[0038] A plurality of exhaust pipes 502 are fixedly connected to the vacuum tube 501 by bolts, and the plurality of exhaust pipes 502 are all connected to a vacuum pump. When the plastic passes through the vacuum tube 501, the vacuum pump is used to evacuate the inside of the vacuum tube 501 through the plurality of exhaust pipes 502, so that the outer wall of the plastic tube can be close to the inner wall of the vacuum tube 501, thereby facilitating the molding of the plastic tube.
[0039] See also Figure 7 ,
[0040] Two anti-wear grooves 503 are provided at one end of the vacuum tube 501 to prevent the rotating rod 402 from rubbing against the vacuum tube 501 and causing wear. The anti-wear grooves 503 facilitate recycling of the two rotating rods 402 .
[0041] See also Figure 7 ,
[0042] The two anti-wear grooves 503 are both arc-shaped. The arc-shaped anti-wear grooves 503 can further reduce the friction between the inner wall of the vacuum tube 501 and the rotating rod 402 , reduce wear and tear, and extend the service life of the rotating rod 402 .
[0043] A water pipe manufacturing process, the process comprising the following steps:
[0044] Step 1: The extrusion head 101 is fixedly connected to the screw extruder by bolts, and the plastic particles are heated to a molten state and extruded by the screw extruder, and the molten plastic is extruded in a tubular shape under the cooperation of the extrusion head 101 and the forming column 102;
[0045] Step 2: Install the traction tube on the traction column 401, move the traction column 401 close to the molding column 102, wrap the traction tube on the traction column 401 when the plastic is extruded, and the extruded plastic uses the residual heat to heat the traction tube and merge with the traction tube, and control the two connecting covers 301 to buckle with each other, and use the extrusion force generated by the two connecting covers 301 to extrude the plastic and the traction tube;
[0046] Step 3: cold water is transmitted to the connection cover 301 through the connection pipe 303. When the two connection covers 301 squeeze the plastic and the traction tube, the cold water diffuses outward through the guide groove 302 in the connection cover 301, cooling and shaping the plastic and the traction tube, so that the connection between the plastic and the traction tube is hardened;
[0047] Step 4: The traction column 401 moves backward to pull the plastic, and the two rotating rods 402 are in contact with the inner wall of the vacuum tube 501, so that the two rotating rods 402 rotate and shrink at the same time;
[0048] Step 5: Use a vacuum pump to evacuate the inside of the vacuum tube 501 through multiple vacuum tubes 502 so that the outer wall of the plastic tube is in close contact with the inner wall of the vacuum tube 501 .
