Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and more specifically, to a single-wall corrugated pipe manufacturing equipment with a two-outlet design. Background Technology

[0002] The production process of single-wall corrugated pipes involves feeding raw materials into a screw barrel. The screw, driven by an extruder motor, melts the granular raw materials into a plastic fluid. The fluid is then extruded through a die into a shaping die, and after being pulled out of the shaping die, it is wound and packaged. Existing equipment can produce different products by changing the shaping die, die, and mandrel, but each machine can only produce one corrugated pipe at a time, resulting in low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a single-wall corrugated pipe production equipment with one output and two outlets.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] This utility model discloses a single-wall corrugated pipe production equipment with one-to-two output, including an extrusion mechanism, a feeding mechanism, and a cooling and shaping mechanism. The extrusion mechanism includes a barrel with a material cavity inside. One end of the material cavity is the inlet end, and the other end is the outlet end. The diameter of the material cavity gradually decreases from the inlet end to the outlet end. A conveying screw is rotatably installed inside the material cavity. One end of the conveying screw extends out of the inlet end of the material cavity and is connected to the drive mechanism. A distributor is installed at the outlet end of the material cavity. The distributor has two distribution channels inside. The two distribution channels are connected and communicate with the material cavity at their ends near the material cavity. The other ends of the two distribution channels are connected to the side of the distributor away from the barrel. A die is installed at the end of the distribution channel that communicates with the side of the distributor. A mandrel is installed inside the die. The end of the die away from the distributor extends into the cooling and shaping mechanism. The outlet of the feeding mechanism is connected to the material cavity inside the barrel.

[0006] Furthermore, the cooling and shaping mechanism includes a shaping mechanism and a cooling water channel. The shaping mechanism includes two parallel guide rails, in which several shaping molds are slidably arranged. The shaping molds in the two guide rails move in opposite directions. When the shaping molds in the two guide rails move to the middle position, they mesh to form a shaping section. A cooling water channel is provided below the shaping section.

[0007] Furthermore, a shaping cavity is provided on the side of the shaping mold, and the shaping cavity is positioned opposite to the mold when the shaping mold moves to the middle position.

A transmission gear is connected to the middle of the rotating shaft, and drive gears are connected to both ends of the rotating shaft. A rack is provided at the lower end of the shaping mold. The two drive gears can mesh with the shaping mold located in the two guide rails respectively. The second drive motor is connected to a drive gear, and a transmission belt connects the drive gear and the transmission gear.

[0010] Furthermore, the drive mechanism includes a drive motor, which is connected to a drive shaft, and the drive shaft and the conveying screw are connected by a coupling.

[0011] Furthermore, the feeding mechanism includes a feed hopper, which is installed on the material cylinder. The lower opening of the feed hopper is connected to the material cavity.

[0013] Furthermore, it also includes a coiling mechanism, which includes a coiling seat, on which a coiling frame is rotatably mounted, and the coiling frame is driven to rotate by an external mechanism such as a motor.

[0014] Furthermore, a pressure rod is rotatably installed on the upper part of the tube seat, and the pressure rod is located above the tube frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a single-wall corrugated pipe production equipment with one-to-two outputs includes an extrusion mechanism, a feeding mechanism, a cooling and shaping mechanism, and a coiling mechanism. The extrusion mechanism includes a frame 1, with a support base 8 on the upper part of the frame 1. A material cylinder 2 is mounted on the support base 8, and a material cavity 3 is provided inside the material cylinder 2. The material cavity 3 is arranged along the axial direction of the material cylinder 2, with the left end of the material cavity 3 being the feed end and the right end being the discharge end. The diameter of the material cavity 3 gradually decreases from the feed end to the discharge end. A conveying screw 4 is rotatably installed inside the material cavity 3. The left end of the conveying screw 4 extends out of the feed end of the material cavity 3 and is connected to the drive mechanism. The diameter of the spiral blades on the conveying screw 4 matches the diameter of the material cavity 3, gradually decreasing from left to right. The drive mechanism includes a drive motor 6, which drives a drive shaft 5 via belt transmission. The drive shaft 5 and the conveying screw 4 are connected by a coupling 7. The drive mechanism drives the conveying screw 4 to rotate within the material chamber 3, conveying the material fed into the material chamber 3 from the inlet to the outlet. The material cylinder 2 has a heating function, which can melt granular raw materials into plastic fluid.

[0024] A distributor 15 is installed at the right end of the material cylinder 2, and a perforated plate 17 is installed between the distributor 15 and the material cylinder 2. The distributor 15 has two distribution channels 16 inside. The left ends of the two distribution channels 16 are connected together and communicate with the right end of the material cavity 3. The right ends of the two distribution channels 16 are spaced apart vertically and communicate with the right side of the distributor 15. A die 18 is installed on the right side of the distributor 15, located at the connection between the distribution channels 16 and the side of the distributor 15. A mandrel 19 is installed inside the die 18. The end of the die 18 away from the distributor 15 extends into the cooling and shaping mechanism. The outlet of the feeding mechanism communicates with the material cavity 3 inside the material cylinder 2. There are two cooling and shaping mechanisms, and the two dies 18 extend into their respective cooling and shaping mechanisms. The material enters the distributor 15 from the right end of the material chamber 3. The material then enters one end of the two connecting channels 16, and is then split to the other end, finally being extruded from the die 18 to form a tube blank. The tube blank enters the shaping mechanism 21, where it is cooled and shaped to form a single-wall corrugated pipe. Because there are two channels 16, two single-wall corrugated pipes can be produced simultaneously.

[0025] like Figure 2 As shown, the coiling mechanism is located at a certain distance to the right of the cooling and shaping mechanism. The coiling mechanism includes a coiling seat 23, on which a coiling frame 24 is rotatably mounted. The coiling frame 24 is driven to rotate by an external mechanism such as a motor. A pressing rod 25 is rotatably mounted on the upper part of the coiling seat 23, positioned above the coiling frame 24. The produced single-wall corrugated pipes are wound and collected by the coiling frame 24. The pressing rod 25 presses against the corrugated pipe to limit its movement and prevent it from deviating during the winding process.

[0026] like Figure 1 , Figure 3 , Figure 4 As shown, the cooling and shaping mechanism includes a shaping mechanism 21 and a cooling channel 22. The shaping mechanism 21 includes two parallel guide rails 26, which are racetrack-shaped. Several shaping molds 27 are slidably disposed within the guide rails 26, and shaping cavities 29 are formed on the sides of the shaping molds 27. The shaping molds 27 move within the guide rails 26 along the shape of the guide rails 26. The shaping molds 27 in the two guide rails 26 move in opposite directions. When the shaping molds 27 in the two guide rails 26 reach the middle position, they engage, and the shaping cavities 29 in the two shaping molds 27 are joined together to form a shaping cavity. The several shaping molds 27 located at the middle position form a shaping section 28. A cooling channel 22 is disposed below the shaping section 28. The cooling channel 22 cools the shaping molds 27 in the upper shaping section 28, so that the material is cooled and formed within the shaping molds 27 in the shaping section 28.

[0027] like Figure 3As shown, in this embodiment, the shaping mold 27 in the front guide rail 26 moves clockwise and the shaping mold 27 in the rear guide rail 26 moves counterclockwise, so that the moving direction of the shaping mold 27 in the shaping section 28 is consistent with the material conveying direction, which can drive the corrugated pipe forward.

[0028] The cooling and shaping mechanism also includes an insulation box 20, a shaping section 28, and a cooling water channel 22 located inside the insulation box 20, which can provide insulation and prevent external temperature influences.

[0029] like Figure 5 As shown, the cooling and shaping mechanism also includes a rotating shaft 31 and a second drive motor 34. A transmission gear 32 is connected to the middle of the rotating shaft 31, and drive gears 33 are connected to both ends of the rotating shaft 31. A rack 30 is provided at the lower end of the shaping mold 27. The two drive gears 33 can respectively mesh with one of the shaping molds 27 located in the two guide rails 26. The second drive motor 34 drives a driving gear, and a transmission belt connects the driving gear and the transmission gear 32. The drive gear 33 meshes with the rack 30 at the lower part of one of the shaping molds 27 in the guide rail 26. The second drive motor 34 drives the transmission gear 32 to rotate, and the transmission gear 32 drives the drive gear 33 to rotate through the rotating shaft 31. The drive gear 33 then drives the shaping mold 27 to move through its engagement with the rack 30. The shaping mold 27 pushes the other shaping molds 27 to move along the guide rail 26. The rotating shaft 31 drives the drive gears 33 at both ends to rotate at the same speed, so that the shaping molds 27 in the two guide rails 26 move at the same speed.

[0030] Since a cooling water channel 22 is to be installed below the shaping section 28 in the middle position for cooling, the drive gear 33 is configured to mesh with the shaping mold 27 located in the outer part of the guide rail 26, so as not to affect the arrangement of the cooling water channel 22.

[0031] like Figure 1 As shown, the feeding mechanism includes a feed hopper 11, which is mounted on the material cylinder 2. The lower opening of the feed hopper 11 is a discharge port and is connected to the material chamber 3. A main feed hopper 9 and an auxiliary feed hopper 10 are provided on the feed hopper 11, and the lower ends of the main feed hopper 9 and the auxiliary feed hopper 10 are connected to the upper end of the feed hopper 11. A feeding channel 12 is connected to the lower part of the main feed hopper 9. One end of the feeding channel 12 is connected to the upper end of the feed hopper 11, and the other end of the feeding channel 12 is provided with a feeding motor 13. The feeding motor 13 drives a feeding screw 14, which is located inside the feeding channel 12. Since a large amount of material is fed into the main feed hopper 9, to avoid blockage of the feed hopper 11 due to rapid material discharge, the discharge port of the main feed hopper 9 is offset from the upper end of the feed hopper 11. The feeding screw 14 is driven to rotate by the feeding motor 13, which slowly feeds the material from the discharge port of the main hopper 9 into the feed hopper 11. The material in the auxiliary hopper 10 is relatively small and can be directly fed into the feed hopper 11.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
