Description

Technical Field

[0001] The invention belongs to the technical field of water pipe processing equipment, and particularly relates to a plastic PE water pipe forming and heating device. Background Art

[0002] With the continuous development of current science and technology, PE (polyethylene) material is widely used in the field of water pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water pipes. During the production process of plastic PE water pipes, it is usually necessary to heat and melt the plastic particles, and then extrude the molten plastic through an extrusion device. However, due to the inconsistent particle sizes of the plastic particles, the melting rates of large-size particles and small-size particles are different when heated and melted, that is, when the small-size plastic is completely melted, the large-size plastic particles are still not completely melted, and excessive heating will cause the molten plastic to coke. Therefore, there may be plastic particles that are not completely melted in the extruded water pipe, which will affect the quality of the manufactured water pipe. In the existing technology, when the plastic particles are melted, most of them lack the problem of screening and separating the large-size plastic particles and discharging them in time.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the plastic PE water pipe forming heating device includes a base 100, which is characterized by:

[0034] The base 100 is provided with a melt extrusion mechanism 200, which includes a barrel 201 fixed to the base 100 and having an open end. The barrel 201 is provided with an extrusion head 202 in the opening. Multiple groups of heating units 203 are provided on the outer peripheral wall of the barrel 201. The barrel 201 is provided with an extrusion unit for extruding the molten material in the barrel 201 toward the end of the extrusion head 202.

[0035] A feeding funnel 300 is fixed to the side wall of the end of the barrel 201 away from the extruder head 202. The feeding funnel 300 is connected to the interior of the barrel 201. A pair of connecting plates 400 are fixed to the side walls of the feeding funnel 300. A storage box 500 is fixed to the end of the connecting plate 400 away from the feeding funnel 300. The storage box 500 is used to store the plastic particles to be melted.

[0036] A horizontally placed filter plate 600 is fixed between the two connecting plates 400. The filter plate 600 is provided with a plurality of filter holes. One end of the filter plate 600 is in contact with the side wall of the feed funnel 300. A collection bin 700 is provided at the end of the filter plate 600 away from the feed funnel 300.

[0037] A belt conveyor mechanism 800 is provided between the two connecting plates 400 and is located below the filter plate 600. A strip groove is provided on the side wall of the feed funnel 300, and one end of the belt conveyor mechanism 800 passes through the strip groove and extends into the inner side of the feed funnel 300.

[0038] A material taking mechanism 900 is provided directly above the filter plate 600. The material taking mechanism 900 is used to take plastic particles from the storage box 500 and push them onto the filter plate 600. At the same time, the plastic particles on the filter plate 600 that cannot pass through the filter holes are discharged into the collection bin 700.

[0039] The material taking mechanism 900 extracts some plastic particles from the storage box 500 and filters them on the filter plate 600. The small-sized plastic particles pass through the filter plate 600 and fall onto the belt conveyor mechanism 800. They are then conveyed to the feeding funnel 300 by the belt conveyor mechanism 800, and finally enter the bobbin 201 through the feeding funnel 300. The small-sized plastic particles in the bobbin 201 are heated and melted by the heating unit 203, and the plastic PE water supply pipe is extruded and formed by the cooperation of the extrusion unit and the extrusion head 202. The coordinated arrangement of the material taking mechanism 900, the conveying mechanism 800 and the filter plate 600 can screen and discharge the large-sized plastic particles in the plastic particles, thereby preventing the large-sized plastic particles from entering the sleeve and affecting the quality of the extruded water supply pipe.

[0040] The material taking mechanism 900 takes small amounts of material from the storage box 500 continuously and multiple times, which can prevent plastic particles from clogging the feed funnel 300. At the same time, the large-sized particles on the filter plate 600 are discharged into the collection bin 700 through the material taking mechanism 900, so that the filter plate 600 can be cleaned in time after each filtration, avoiding large-sized plastic particles from gathering on the filter plate 600 and clogging the filter holes, thereby affecting the filtration efficiency.

[0041] Preferably, the connecting plate 400 extends horizontally from the feed hopper 300 to the extrusion head 202 end, and the lower end of the storage box 500 is fixedly supported on the upper end of the melt extrusion mechanism 200.

[0042] A notch is provided at the upper end of the box wall of the storage box 500 near the feed funnel 300, and the lower end wall of the notch is flush with the upper end surface of the filter plate 600. A baffle 501 for sealing the notch is provided on the side of the storage box 500 near the feed funnel 300, and a first telescopic cylinder 502 for driving the baffle 501 to move up and down is installed on the side wall of the storage box 500.

[0043] The material taking mechanism 900 includes a first screw 901 horizontally arranged just above the filter plate 600, the first screw 901 and the connecting plate 400 are coaxially placed, one end of the first screw 901 is rotatably connected to the end of the storage box 500 away from the feeding funnel 300, and the other end of the first screw 901 is rotatably connected to the feeding funnel 300, and a first rotating motor 902 that drives the first screw 901 to rotate is installed on the storage box 500, and a sliding rod coaxially placed with the first screw 901 is fixed between the storage box 500 and the feeding funnel 300. 01 is provided with a threaded sliding bar 903, which is sleeved on the sliding bar and slidably connected thereto. A vertically placed material-dipping plate 904 is provided below the first screw 901. Both ends of the material-dipping plate 904 are respectively fitted with the two connecting plates 400, and both ends of the material-dipping plate 904 are respectively flush with the two side plates of the material storage box 500 close to the connecting plate 400. The material-dipping plate 904 can slide through the notch. A pair of second telescopic cylinders 905 placed vertically downward are fixed on the sliding bar 903, and the output ends of the second telescopic cylinders 905 are both connected to the material-dipping plate 904.

[0044] In the initial state, the first telescopic cylinder 502 drives the baffle 501 to move up to block the notch and keep the depth of the plastic particles in the storage box higher than the upper end surface of the filter plate 600. Then, the first rotary motor 902 is turned on to drive the first screw 901. The first screw 901 drives the slide bar 903 to perform threaded transmission, so that the slide bar 903 drives the second telescopic cylinder 905 and the material stripping plate 904 from the feed funnel 300 end to the storage box 500 end. When the material stripping plate 904 contacts the baffle 501, the first telescopic cylinder 502 is turned on to drive the baffle 501 to move down, so that the material stripping plate 904 can pass through the notch. After the material stripping plate 904 passes through the notch, the baffle 501 is driven up again by the first telescopic cylinder 502 to block the notch. ; Then, while the slide bar 903 continues to move away from the end of the feed funnel 300, the second telescopic cylinder 905 is turned on to drive the material stripping plate 904 to move upward, so that the plastic particles in the storage box enter between the baffle 501 and the material stripping plate 904 from the lower end of the material stripping plate 904, and then the second telescopic cylinder 905 drives the material stripping plate 904 to move downward, so that the lower end surface of the material stripping plate 904 is flush with the upper end surface of the filter plate 600; finally, the first rotary motor 902 drives the first screw 901 to rotate in the opposite direction, and cooperates with the first telescopic cylinder 502 to drive the baffle 501 to move up and down, so that the material stripping plate 904 pushes the plastic particles to move onto the filter plate 600, and the material stripping plate 904 pushes the plastic particles to move on the filter plate 600, which can improve the screening efficiency of the plastic particles.

[0045] The collecting bin 700 is located between the filter plate 600 and the storage box 500. The collecting bin 700 is fixed to the connecting plates 400 on both sides.

Do not fit with the two connecting plates 400; the plastic particles picked out from the storage box 500 by the material taking mechanism 900 are located between the push plate 906 and the material picking plate 904. After each screening is completed, the first rotating motor 902 and the first screw 901 drive the push plate 906 and the material picking plate 904 to move away from the end of the feed funnel 300, and move the cover plate 701 above the collection bin 700. At this time, the large-size plastic particles on the filter plate 600 can be pushed into the collection bin 700 through the push plate 906.

[0047] In order to facilitate the automatic control of the opening and closing of the open side of the collecting bin 700, the cover 701 is slidably connected to the collecting bin 700, and a through groove for the cover 701 to pass through is opened on any connecting plate 400.

[0048] In order to facilitate the upward movement of the plastic particles at the bottom of the storage box 500 and avoid the upper end surface of the plastic particles in the storage box 500 being lower than the upper end surface of the filter plate 600, there is no need to perform normal material removal work, a loading plate 503 is slidably connected to the storage box 500, and the peripheral wall of the loading plate 503 is in contact with the peripheral wall of the storage box 500.
