Description

Technical Field

[0001] The present invention relates to the technical field of pipe production, and particularly relates to a pipe extrusion forming device. Background Art

[0002] Currently, in the production process of pipe extrusion forming, white materials and color powders are added to a mixing device for stirring and mixing, and then the mixed materials are transported to an extrusion device to produce pipes of the required color. However, when producing products of different colors, for example, after producing blue and gray pipes and then producing white pipes, in order to avoid mutual color contamination, operators need to clean the mixing device before it can be used to produce white pipes, which is labor-intensive, time-consuming and laborious, and the production efficiency is relatively low. In the prior art, in order to improve production efficiency, the mixing device is usually dedicated to a special machine, and multiple mixing devices are equipped to complete the production of products of different colors. This not only lacks flexibility in production, but also has a relatively high equipment investment cost. Summary of the Invention

[0033] As Figures 1 to 5 shown, the pipe extrusion molding device according to an embodiment of the present invention includes: a frame 10; an extrusion device 20 provided on the frame 10, and an inlet 21 and an outlet 22 are provided on the extrusion device 20; a main feeding device 30 provided on the frame 10, and a first feeding port 31 and a first discharging port 32 through which materials can be introduced are provided on the main feeding device 30; a color powder adding device 40 provided on the frame 10, and a second feeding port 41 and a second discharging port 42 through which color powder can be introduced are provided on the color powder adding device 40; a mixing device 50 movably provided on the frame 10, and the mixing device 50 is used for stirring and mixing the materials and the color powder. The mixing device 50 is provided with a third feeding port 51 and a third discharging port 52, and the mixing device 50 has at least a first working position and a second working position; when the mixing device 50 is in the first working position, the first discharging port 32, the second discharging port 42 and the third feeding port 51 are connected, and the third discharging port 52 is connected to the inlet 21; when the mixing device 50 is in the second working position, the first discharging port 32 is connected to the inlet 21.

[0034] According to the pipe extrusion forming equipment of the embodiments of the present invention, with the above structure, by movably arranging the mixing device 50 on the frame 10, when the mixing device 50 is in the first working position, the first discharge port 32, the second discharge port 42 and the third feed port 51 are connected through a cloth bag, the third discharge port 52 is connected with the feed port 21, the white material introduced into the main feeding device 30 and the color powder in the color powder adding device 40 can be transported into the mixing device 50, after being stirred and mixed by the mixing device 50, and then transported to the extrusion device 20, so as to complete the production of pipes such as blue or gray; when the mixing device 50 is in the second working position, the first discharge port 32 is connected with the feed port 21 through a cloth bag, at this time, the color powder adding device and the mixing device 50 stop working, and the main feeding device 30 directly transports the white material through the first discharge port 32 into the extrusion device 20, so as to complete the production of white pipes, which can quickly switch from the production of blue or gray pipes to the production of white pipes, and vice versa, can also quickly switch from white pipes to the production of blue or gray pipes, with flexible production, realizing flexible production of pipes of different colors according to the actual needs of the production workshop, reducing the need for the number of mixing devices 50 for different color formulations, reducing the cleaning of the production line by operators when switching the production of different color products, and reducing the equipment investment cost of the production workshop.

[0035] It should be noted that, in some embodiments of the present invention, the mixing device 50 is installed on one side of the extrusion device 20, and the main feeding device 30 and the color powder adding device are both installed above the mixing device 50.

[0036] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in some embodiments of the present invention, the mixing device 50 is rotationally connected to the frame 10, and the mixing device 50 can be rotated relative to the frame 10 to the first working position or the second working position. With the above structure, when producing blue pipes or gray pipes, etc., the mixing device 50 rotates to the first working position, and the third feed port 51 of the mixing device 50 is respectively connected with the first discharge port 32 and the second discharge port 42, so that the white material and the color powder of the corresponding color can be stirred and mixed by the mixing device 50 and then transported to the extrusion device 20 for extrusion forming; when producing white pipes, the mixing device 50 is rotated to the second working position, and the first discharge port 32 is connected with the feed port 21, so that the white material directly enters the feed port 21 of the extrusion device 20 through the first discharge port 32, thus completing the extrusion forming, with a simple structure and quick operation, without the need for dedicated use of the mixing device 50, which can further reduce the material transportation of the mixing device 50 and reduce the production cost.

[0037] Of course, in some embodiments, the mixing device 50 can be slidably disposed on the frame 10. When producing blue pipes or gray pipes, etc., the mixing device 50 slides to the third feed port 51 and is respectively connected to the first discharge port 32 and the second discharge port 42; when producing white pipes, the mixing device 50 is slid to the third discharge port 52 and staggered with the feed port 21, and the first discharge port 32 is connected to the feed port 21, which still has the above-mentioned effect.

[0038] It is understandable that if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the mixing device 50 includes: a mixing housing 53, which is rotatably disposed on the frame 10, and the third feed port 51 and the third discharge port 52 are both disposed in the mixing housing 53; a first stirring unit 54, which is rotatably disposed in the mixing housing 53; and a first driving member 55, which is disposed in the mixing housing 53, and the first driving member 55 is transmission-connected with the first stirring unit 54. With the above structure, the mixing housing 53 is rotated, the first discharge port 32, the second discharge port 42 and the third feed port 51 are connected, or the third discharge port 52 is staggered with the feed port 21, and the first discharge port 32 is directly connected with the feed port 21, and the first stirring unit 54 is disposed, and the first driving member 55 is driven, so that the color powder and the white material in the mixing housing 53 are fed and stirred, and the transmission is stable and reliable, and automation is realized.

[0039] It is understandable that if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the first driving member 55 is a first driving motor, and the first stirring unit 54 includes a first stirring shaft 541 connected to the first driving motor shaft and a spiral blade 542 and a stirring blade 543 arranged around the first shaft, wherein the spiral blade 542 is located at the front end of the first shaft, and the stirring blade 543 is located at the rear end of the first shaft, i.e., one end close to the extrusion device 20, and the material is fed to the first stirring blade 543 through the first spiral blade 542, thereby completing the stirring and feeding. The stirring blade 543 includes two plates, which are arranged to be relatively inclined and have an angle, so as to further enable rapid feeding, thereby achieving the mixing and stirring of the white material and the toner, with a fast stirring speed and a good material mixing effect.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in some embodiments of the present invention, the mixing shell 53 is connected to a blanking sleeve at the third discharge port 52, and an annular fixing piece is provided at one end of the blanking sleeve. When the third discharge port 52 is connected to the feed port 21, the blanking sleeve is sleeved with the feed port 21 of the extrusion device 20 through the annular fixing piece and locked by the tightening piece, so that the mixed material can enter the feed port 21 through the blanking sleeve; when it is necessary to produce white pipes, the tightening piece is operated to stagger the blanking sleeve and the feed port 21, so that the mixing shell 53 can be rotated, which has a simple structure, reliable positioning, and convenient operation.

[0041] It should be noted that, in some embodiments of the present invention, the mixing shell 53 is rotated by an operator. Of course, in some embodiments, the mixing shell 53 can also be rotated by a driving motor, which is not limited here.

[0042] It is understandable that if Figures 1 to 5 As shown, in some embodiments of the present invention, the main feeding device 30 is rotatably connected to the frame 10, and the first discharge port 32 can rotate with the main feeding device 30 to be connected to the third feed port 51 or to the feed port 21. With the above structure, when the mixing device 50 is in the first working position, the first discharge port 32 of the main feeding device 30, the second discharge port 42 of the color powder adding device and the third feed port 51 of the mixing device 50 are connected; when the mixing device 50 is rotated to the second working position, the third discharge port 52 and the feed port 21 are staggered. At this time, the main feeding device 30 is rotated so that the first discharge port 32 is connected to the feed port 21 of the extrusion device 20, so that the material can directly enter the extrusion device 20, thereby completing the extrusion molding of the pipe. The operation is flexible and can quickly adapt to the change of the feeding line, further improving the production efficiency of the pipe.

[0043] like Figures 1 to 5 As shown, in some embodiments of the present invention, the main feeding device 30 includes: a mounting frame 33, which is rotatably arranged on the frame 10; a first hopper body 34, which is fixedly connected to the mounting frame 33, and the first hopper body 34 is provided with a first material cavity 341 for placing materials, and a first feed port 31 is arranged on the first hopper body 34, and the first feed port 31 is connected to the first material cavity 341; a feeding cylinder 342 is connected to the first hopper body 34, and a first discharge port 32 is arranged on the feeding cylinder 342, and the feeding end of the feeding cylinder 342 is connected to the first material cavity 341.

With the above structure, the friction caused by the rotation of the mounting frame 33 can be reduced, so that the main feeding device 30 can rotate smoothly.

[0045] It should be noted that, in some embodiments of the present invention, the mounting bracket 33 is fixed to the frame 10 by four screws. When the main feeding device 30 needs to be rotated, it can be adjusted by loosening the screws, so that assembly and adjustment are more convenient.

With the above structure, the power sources of the first feeding unit 37 and the second stirring unit 38 are the same, namely, the driving mechanism 39, which has a simple structure and can further reduce the volume of the equipment. The first feeding unit 37 and the second stirring unit 38 operate synchronously, which can not only loosen and discharge the material in the first material chamber 341, but also can quickly transport the material to the first discharge port 32 through the first feeding unit 37 after discharge, which is helpful to prevent the occurrence of blockage.
