Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel profile extrusion production, in particular to a high-efficiency extruder for plastic-steel profiles. Background Art

[0002] The high-efficiency extruder for plastic-steel profiles is a machine specifically designed for producing plastic-steel door and window profiles, pipes, plates, and other products. The plastic-steel profile extruder melts the PVC pellets at high temperature and pressure, extruding them through a die to form the desired profile.

[0003] After searching, the Chinese patent "An extruder for melting plastic-steel profile raw materials" authorization announcement number "CN214926966U" realizes cooling of the extruder end surface through an extruder, a cooling ring, a water pump, a water inlet pipe, a water outlet pipe and a cooler, so that the extruder end quickly cools the extruded plastic-steel profile. The water outlet pipe in the cooling ring is introduced into the cooler, and the cooler quickly cools the water and introduces it into the water tank, realizing the recycling of water, improving the quality of the plastic-steel profile, and saving water resources at the same time.

[0004] In the above application, the cooling ring is arranged on the surface of the extruder end, so that the cooling ring does not directly contact the plastic-steel profile, resulting in faster heat dissipation on the outer surface of the plastic-steel profile and slower heat dissipation in the middle of the plastic-steel profile, thereby affecting the cooling effect of the plastic profile.

[0005] Therefore, an efficient extruder for plastic-steel profiles is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a high-efficiency extruder for plastic-steel profiles in order to solve the above problems, thereby improving the problem that the heat on the outer surface of the plastic-steel profile dissipates quickly while the heat in the middle of the plastic-steel profile dissipates slowly.

[0013] Preferably, a through hole is provided at the lower end of the surface of the support frame, so as to drain water splashed into the support frame and prevent the water from being retained in the support frame.

[0014] Preferably, the upper surface end of the drain pipe is in the shape of a square funnel.

[0015] The beneficial effects of the utility model are:

[0016] 1.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a high-efficiency extruder for plastic-steel profiles comprises: a workbench 1, an extruder 2 is fixedly connected to the top of the workbench 1, a water tank 3 is fixedly connected to one side of the workbench 1, the top of the water tank 3 is fixedly connected to a cooler 4, and the top of the water tank 3 is fixedly connected to a water pump 5; a cooling mechanism 6, the cooling mechanism 6 is arranged on the top of the workbench 1; wherein, the cooling mechanism 6 comprises a water supply frame 61 provided on the top of the workbench 1, the upper end of the surface of the water pump 5 is fixedly connected to the inner wall of the water supply frame 61, and one end of the inner wall of the water supply frame 61 is fixedly connected to two sealed bearings 65, the inner edge of one sealed bearing 65 is fixedly connected to a nozzle 62, and the outer edge of the other sealed bearing 65 is fixedly connected to the inner surface of the nozzle 62, the outer surface of the nozzle 62 is fixedly connected to a gear ring 63, and the surface of the gear ring 63 is meshedly connected to a gear 64.

[0025] The sealed bearing 65 ensures that the nozzle 62 will not drive the water delivery frame 61 to rotate during rotation. The ring gear 63 and the gear 64 are both stainless steel components. The upper end of the surface of the extruder 2 is fixedly connected to a storage barrel, and the top end of the storage barrel is fixedly connected to a feed pipe.

[0026] When producing plastic-steel profiles, the PVC granular raw material in the storage barrel is transported to the extruder 2. The PVC granular raw material gradually melts under the shearing and heating action of the screw in the extruder 2. A PID controller is usually used to ensure that the temperature in the extruder 2 is stable, so that the extruder 2 can efficiently produce plastic-steel profiles and mix evenly with various additives such as stabilizers, lubricants, colorants, etc. The molten PVC material is extruded through the mold on the end of the extruder 2 to form the required plastic-steel profile. At this time, the water pump 5 is manually turned on, and the water pump 5 draws water from the water tank 3 and transports it to the water supply frame 61. The water in the water supply frame 61 is transported to the nozzle 62, driving the gear 64 to rotate. The rotation of the gear 64 drives the ring gear 63 and the nozzle 62 to rotate. The rotating nozzle 62 sprays cold water on the extruded plastic-steel profile in all directions, so that the surface of the plastic-steel profile is evenly cooled, so that it solidifies and maintains its shape, so that the extruder efficiently cools the surface of the plastic-steel profile.

[0027] like Figure 2 As shown, the top of the workbench 1 is fixedly connected to a shielding frame 610, the surface of the gear 64 is rotatably connected to the inner wall of the shielding frame 610, the lower end of the surface of the water supply frame 61 is fixedly connected to the inner bottom wall of the shielding frame 610, and one side of the shielding frame 610 is fixedly connected to a servo motor 66, and the output shaft of the servo motor 66 is fixedly connected to one end of the gear 64.

[0028] like Figure 2As shown, the inner bottom wall of the shielding frame 610 is fixedly connected to a drain pipe 67, the bottom end of the drain pipe 67 is fixedly connected to the top of the cooler 4, the upper end of the inner wall of the drain pipe 67 is fixedly connected to a filter screen 69, and the lower end of the inner wall of the shielding frame 610 is fixedly connected to a guide plate 612, the top of the guide plate 612 forms an angle with the horizontal plane, and the upper end of the surface of the drain pipe 67 is in the shape of a square funnel.

[0029] The cold water sprayed on the surface of the plastic steel falls onto the guide plate 612. Since the guide plate 612 is set at an angle, the water quickly flows into the filter screen 69. The filter screen 69 filters the water. The filtered water flows into the cooler 4 through the drain pipe 67. The cooler 4 is manually opened and the cooler 4 cools the inflowing water. The cooled water flows into the water tank 3 so that the water can be recycled.

[0030] like Figure 3 As shown, the inner bottom wall of the shielding frame 610 is fixedly connected to the supporting frame 68 , the lower end of the surface of the nozzle 62 is rotatably connected to the inner wall of the supporting frame 68 , and the lower end of the surface of the supporting frame 68 is provided with a through hole 611 .

[0031] When the utility model is in use, the PVC granular raw material in the storage barrel is transported to the extruder 2, and the PVC granular raw material gradually melts under the shearing and heating action of the screw in the extruder 2. A PID controller is usually used to ensure that the temperature in the extruder 2 is stable, so that the extruder 2 can efficiently produce plastic-steel profiles and evenly mix with various additives such as stabilizers, lubricants, colorants, etc. The molten PVC material is extruded through the die on the end of the extruder 2 to form the required plastic-steel profile. At this time, the water pump 5 and the servo motor 66 are manually turned on, and the water pump 5 draws water from the water tank 3 and transports it to the water delivery frame 61. The water in the water delivery frame 61 is transported to the nozzle 62, and the servo motor 66 is manually turned on. The output shaft of the servo motor 66 rotates through the gear 64 and the ring gear 63 to drive the nozzle 62 to rotate. The nozzle 62 rotates on the support frame 68 and sprays cold water on the extruded plastic-steel profile in all directions, so that the surface of the plastic-steel profile is evenly cooled, so that it solidifies and maintains its shape. The cold water sprayed on the surface of the plastic-steel profile falls on the guide plate 612. Because the guide plate 612 is inclined, the water quickly flows into the filter screen 69, and the filter screen 69 filters the water. The filtered water flows into the cooler 4 through the drain pipe 67. The cooler 4 is manually opened, and the cooler 4 cools the inflowing water. The cooled water flows into the water tank 3, so that the water can be recycled.

[0032] It should be noted that the workbench 1, extruder 2, cooler 4, water pump 5, servo motor 66 and sealed bearing 65 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the extruder 2, cooler 4, water pump 5 and servo motor 66 can be powered by a built-in power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
