Description

Technical Field

[0001] This application relates to the technical field of pipe injection molding, and specifically relates to a pipe injection molding and extrusion device. Background Art

[0002] The pipe injection molding and extrusion device is a device used in the production and processing field, mainly for the extrusion molding process of plastic pipes.

[0003] Most of the existing pipe injection molding and extrusion devices will have uneven distribution of plastic particles in the material extrusion chamber, resulting in uneven heating of the plastic particles, so that air bubbles are likely to appear in the melted plastic liquid. Moreover, most of the existing pipe injection molding and extrusion devices exhaust the air in the plastic solution by extrusion force during the process of pushing the plastic solution to one end. However, when the extrusion force extrudes the plastic solution, the contact area with the plastic solution is small, which easily causes air bubbles to be incompletely exhausted in the plastic solution. The generated air bubbles are likely to affect the structural integrity of the plastic pipe after molding, and may cause the plastic pipe to crack during use.

[0004] Therefore, it is necessary to provide a pipe injection molding and extrusion device to solve the above problems.

Through the arranged second feeding screw, multiple stirring blade rods, filter plate, first conveying pipe, collection chamber, second diversion ball rod, second conveying pipe, first diversion ball rod, multiple comb rods and heating block, during the process that the second feeding screw rotates to push the material and molten material towards one end, when the multiple stirring blade rods fixedly connected to the rotating second feeding screw contact the molten material, they will stir the molten material, push the unmelted material towards the inner wall of the extrusion chamber, and the high temperature on the inner wall of the extrusion chamber melts the material. When the liquid of molten plastic particles contacts the filter plate under the pushing force, the filter plate filters the plastic particles that are not completely melted and simultaneously filters the unmelted impurities contained in the molten plastic liquid. The filtered molten material will enter the collection chamber opened in the first conveying pipe. When the collection chamber is filled with molten material, the molten material that continues to flow into the collection chamber will push the molten material in the collection chamber to flow along the second diversion ball rod towards one end, and flow along the hemispherical block fixedly connected to one end of the second diversion ball rod into the diversion cavity formed between the diversion ball and the inner walls of the second conveying pipe and the first conveying pipe.

The multiple comb rods comb and extrude the molten material, combing the aggregated molten material apart. At this time, the gas in the molten material will be discharged, and the heat emitted by the heating block arranged in the diversion ball will assist in heating or keeping warm the flowing molten liquid, facilitating the re-uniform melting of the material that is not completely melted in the combed and extruded molten material, being beneficial to improving the uniformity of heat absorption of plastic particles, reducing the generation of bubbles, and simultaneously facilitating the filtration and combing extrusion of the melted plastic solution before the plastic melt is extruded, being beneficial to improving the exhaust effect of the plastic solution, thereby improving the effect of pipeline injection molding.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Such as Figure 1-7As shown in the figure, the present application provides a pipeline injection molding and extrusion device, including a protective cabin 5 and a base plate 1. The protective cabin 5 is fixedly installed on the base plate 1. One end of the protective cabin 5 is provided with a defoaming mechanism 6. The defoaming mechanism 6 includes a first conveying pipe 61 located at one end of the protective cabin 5. One end of the first conveying pipe 61 is provided with a second conveying pipe 62. A collecting cavity 68 is opened in both the first conveying pipe 61 and the second conveying pipe 62. A second guide ball rod 67 is arranged in the collecting cavity 68 of the first conveying pipe 61, and a first guide ball rod 65 is arranged in the collecting cavity 68 of the second conveying pipe 62. A filter plate 69 is threadedly connected to one end of the second guide ball rod 67. Hemispherical blocks are fixedly connected to one end of the first guide ball rod 65 and the other end of the second guide ball rod 67. A plurality of comb rods 66 are fixedly connected to the hemispherical blocks at equal intervals. The hemispherical block fixed on the first guide ball rod 65 and the hemispherical block fixed on the second guide ball rod 67 are engaged with each other to form a drainage ball. A heating block 610 is arranged in the drainage ball. There is a drainage cavity between the drainage ball and the inner walls of the second conveying pipe 62 and the first conveying pipe 61. One end of the second conveying pipe 62 is fixed with an extrusion head 63 by a clamp. A fixed disk 611 is fixedly connected to the end of the extrusion head 63 close to the second conveying pipe 62. A plurality of discharge ports 612 are equidistantly opened on the fixed disk 611. A shaping rod 64 is fixedly connected to one end of the fixed disk 611. A pipeline forming die cavity is formed between the shaping rod 64 and the inner wall of the extrusion head 63. The other end of the first guide ball rod 65 is threadedly connected to the fixed disk 611.

[0032] In this embodiment, when the molten liquid of plastic particles contacts the filter plate 69 under the pushing force, the filter plate 69 filters the plastic particles that have not been completely melted, and at the same time filters the unmeltable impurities contained in the molten plastic liquid. The filtered molten material will enter the collecting cavity 68 opened in the first conveying pipe 61. When the collecting cavity 68 is filled with the molten material, the molten material that continues to flow into the collecting cavity 68 will push the molten material in the collecting cavity 68 to flow along the second diversion ball rod 67 towards one end, and flow along the hemispherical block fixedly connected to one end of the second diversion ball rod 67 into the diversion cavity formed between the diversion ball and the inner walls of the second conveying pipe 62 and the first conveying pipe 61. When it flows to the hemispherical block at one end of the first diversion ball rod 65, it will flow along the hemispherical block at one end of the first diversion ball rod 65 towards one end. During the process of the molten material flowing along the diversion ball composed of two hemispherical blocks towards one end, the molten material will sequentially pass through the combing gaps formed between the multiple comb rods 66 fixed on the hemispherical blocks fixedly connected to the second diversion ball rod 67 and the first diversion ball rod 65. The multiple comb rods 66 comb and extrude the molten material, separating the aggregated molten material. At this time, the gas in the molten material will be discharged, and at the same time, the heat emitted by the heating block 610 provided in the diversion ball will assist in heating or keeping warm the flowing molten liquid, facilitating the re-uniform melting of the materials that have not been completely melted in the combed and extruded molten material. When the molten material enters the collecting cavity 68 opened in the second conveying pipe 62 along the first diversion ball rod 65, it will enter the pipe forming die cavity formed between the shaping rod 64 and the inner wall of the extrusion head 63 through the multiple discharge ports 612 opened on the fixing plate 611 provided at one end of the collecting cavity 68, forming a pipe model. The formed pipe model will slide along the shaping rod 64 towards one end under the pushing of the molten material that continues to be pushed into the pipe forming die cavity formed between the shaping rod 64 and the inner wall of the extrusion head 63. When the pipe model slides out of the extrusion head 63, the external air will initially cool and shape the pipe model on the shaping rod 64 naturally. The initially shaped pipe model will slide along the shaping rod 64 into the cooling device under the pushing of the molten material.

[0033] It should be noted that a first flange is fixedly connected at the connection position of the second conveying pipe 62 and the first conveying pipe 61. The first flange fixed at one end of the second conveying pipe 62 is fixedly connected to the first flange fixed at one end of the first conveying pipe 61 through a fixing nut. The other end of the first conveying pipe 61 is fixedly connected with a second flange. At the connection position of the second flange and the protective cabin 5, there is a threaded fixing rod, and the threaded fixing rod is fixedly connected with the protective cabin 5. The second flange and the threaded fixing rod are fixedly connected through a nut.

[0034] As Figure 2 and Figure 3As shown in the figure, an extrusion mechanism 8 is provided inside the protective cabin 5. The extrusion mechanism 8 includes a material extrusion cabin 82 that is connected through the protective cabin 5. A plurality of heating modules 83 are fixedly connected at equal intervals on the material extrusion cabin 82. A second feeding screw 81 passes through the material extrusion cabin 82, and a plurality of stirring blade rods 84 are fixedly connected at the spiral gaps at both ends of the second feeding screw 81.

[0035] In this embodiment, when pushing plastic particles, the material pushed into the material extrusion cabin 82 by the rotating second feeding screw 81 slides in the direction of the first conveying pipe 61. During the sliding process, the high temperature emitted by the plurality of heating modules 83 provided on the material extrusion cabin 82 melts the material inside the material extrusion cabin 82. When the rotating second feeding screw 81 pushes the material and the molten material towards one end, when the plurality of stirring blade rods 84 fixedly connected to the rotating second feeding screw 81 come into contact with the molten material, they will stir the molten material, push the unmelted material towards the inner wall of the material extrusion cabin 82, and the high temperature on the inner wall of the material extrusion cabin 82 melts the material, improving the melting effect of the molten material.

[0036] As Figure 1 and Figure 2 As shown in the figure, a positioning disk 3 is fixed by a clamp at one end of the material extrusion cabin 82. A feeding mechanism 7 is installed on the positioning disk 3. The feeding mechanism 7 includes a storage cabin 71 fixedly connected to the positioning disk 3.

[0037] In this embodiment, when adding plastic particles into the material extrusion cabin 82, the second motor 72 drives the first feeding screw 73 fixedly connected to the output end to rotate. The rotating first feeding screw 73 will push the plastic particles stored in the storage cabin 71 into the material extrusion cabin 82, and the particles entering the material extrusion cabin 82 will slide towards one end under the push of the second feeding screw 81.

[0038] As Figure 1 and Figure 2 As shown in the figure, one end of the base plate 1 is fixedly connected with an installation platform 2.

[0039] In this embodiment, when driving the second feeding screw 81 to rotate, the driving gear 42 fixedly connected to the output end is driven by the first motor 41 to rotate. The rotating driving gear 42 drives the reduction gear 43 meshed at one end to rotate. The rotating reduction gear 43 drives the fixed gear 44 meshed with it to rotate. The rotating fixed gear 44 drives the second feeding screw 81 fixedly connected to the middle to rotate.

[0040] As Figure 3 、 Figure 5 、 Figure 6 and Figure 7 shown, a second docking slot 12 is provided at one end of the fixed disk 611. A second docking head 11 is clamped in the second docking slot 12. One end of the second docking head 11 is fixedly connected to the second conveying pipe 62. A first docking slot 9 is opened at one end of the first conveying pipe 61. A positioning ring 10 is fixedly connected in the first docking slot 9. The second diversion ball rod 67 is threadedly connected to the positioning ring 10. One end of the second diversion ball rod 67 provided in the first conveying pipe 61 is threadedly connected to the second diversion ball rod 67. A first docking head is clamped between the first docking slot 9 and the positioning ring 10. One end of the first docking head is fixedly connected to the material extrusion chamber 82.

[0041] In this embodiment, during installation, the first diversion ball rod 65 is inserted into the second conveying pipe 62 so that one end of the first diversion ball rod 65 penetrates the second conveying pipe 62. The threaded hole opened in the middle of the fixed disk 611 fixedly connected to one end of the extrusion head 63 is sleeved on one end of the first diversion ball rod 65, so that the second docking slot 12 provided at one end of the fixed disk 611 is clamped on the second docking head 11 fixedly connected to one end of the second conveying pipe 62. Then rotate the extrusion head 63 so that the extrusion head 63 is threadedly connected to one end of the second conveying pipe 62, and the first diversion ball rod 65 can be positioned. The second diversion ball rod 67 is inserted into the first conveying pipe 61 so that one end of the second diversion ball rod 67 penetrates one end of the first conveying pipe 61. Then the filter plate 69 is threadedly rotated into the positioning ring 10 fixedly connected to one end of the first conveying pipe 61, so that the threaded hole opened in the filter plate 69 is threadedly connected to one end of the second diversion ball rod 67 to position the second diversion ball rod 67. Then the first conveying pipe 61 is clamped on the second conveying pipe 62 so that the second diversion ball rod 67 is clamped on the first diversion ball rod 65. Then the first conveying pipe 61 and the second conveying pipe 62 clamped together are fixed together through a nut and a first flange. Then the first docking slot 9 opened at one end of the first conveying pipe 61 is clamped on the first docking head fixedly connected to one end of the material extrusion chamber 82, so that the second flange fixedly connected to one end of the first conveying pipe 61 will be clamped on the fixed threaded rod on the protective chamber 5 and fixed with a nut.

[0042] Working principle:

[0043] The driving gear 42 fixedly connected to the output end is driven by the first motor 41 to rotate. The rotating driving gear 42 drives the reduction gear 43 meshed at one end to rotate. The rotating reduction gear 43 drives the fixed gear 44 meshed with it to rotate. The rotating fixed gear 44 drives the second feeding screw rod 81 fixedly connected to the middle to rotate. The first feeding screw rod 73 fixedly connected to the output end is driven by the second motor 72 to rotate. The rotating first feeding screw rod 73 pushes the plastic particles stored in the storage bin 71 into the extrusion bin 82. The material pushed into the extrusion bin 82 by the rotating second feeding screw rod 81 slides in the direction of the first conveying pipe 61. During the sliding process, the high temperature emitted by the multiple heating modules 83 provided on the extrusion bin 82 melts the material in the extrusion bin 82. When the second feeding screw rod 81 rotates and pushes the material and the molten material towards one end, when the multiple stirring blade rods 84 fixedly connected to the rotating second feeding screw rod 81 come into contact with the molten material, they will stir the molten material and push the unmolten material towards the inner wall of the extrusion bin 82. The high temperature on the inner wall of the extrusion bin 82 melts the material. The molten material will flow in the direction of the filter plate 69 under the push of the second feeding screw rod 81. When the molten material contacts the filter plate 69 under the push of the pushing force, the filter plate 69 filters the plastic particles that have not been completely melted and also filters the unmeltable impurities contained in the molten plastic liquid. The filtered molten material will enter the collection cavity 68 opened in the first conveying pipe 61. When the collection cavity 68 is filled with molten material, the molten material that continues to flow into the collection cavity 68 will push the molten material in the collection cavity 68 to flow along the second diversion ball rod 67 towards one end, and flow along the hemispherical block fixedly connected to one end of the second diversion ball rod 67 into the diversion cavity formed between the diversion ball and the inner walls of the second conveying pipe 62 and the first conveying pipe 61. When it flows to the hemispherical block at one end of the first diversion ball rod 65, it will flow along the hemispherical block at one end of the first diversion ball rod 65 towards one end. During the process of the molten material flowing towards one end along the diversion ball composed of two hemispherical blocks, the molten material will successively pass through the combing gaps formed between the multiple comb rods 66 fixed on the hemispherical blocks fixedly connected to the second diversion ball rod 67 and the first diversion ball rod 65. The multiple comb rods 66 comb and extrude the molten material to separate the aggregated molten material. At this time, the gas in the molten material will be discharged. At the same time, the heat emitted by the heating block 610 provided in the diversion ball will assist in heating or keeping warm the flowing molten liquid, facilitating the re-uniform melting of the material that has not been completely melted in the combed and extruded molten material. When the molten material enters the collection cavity 68 opened in the second conveying pipe 62 along the first diversion ball rod 65, it will enter the pipe forming die cavity formed between the shaping rod 64 and the inner wall of the extrusion head 63 through the multiple discharge ports 612 opened on the fixed disk 611 provided at one end of the collection cavity 68, forming a pipe model.The formed pipe model will slide along the shaping rod 64 towards one end under the pushing of the molten material that continues to be pushed into the pipe forming die cavity between the shaping rod 64 and the inner wall of the extrusion head 63. When the pipe model slides out of the extrusion head 63, the external air will conduct preliminary natural cooling and shaping on the pipe model on the shaping rod 64. The preliminarily shaped pipe model will slide along the shaping rod 64 into the cooling device under the pushing of the molten material.,
