Description

Technical Field

[0001] This utility model relates to the field of PE hot melt pipe production technology, and in particular to a material suction device for PE hot melt pipe production. Background Technology

[0002] PE hot-melt pipes are made of polyethylene resin and are joined by hot-melt connection. They are corrosion resistant, flexible, have high compressive strength, and excellent low-temperature performance, and can be used in temperatures ranging from -60℃ to 60℃. The hot-melt joints have high strength and are not prone to leakage. They are used in water supply and drainage, gas transmission and other fields. They are easy to install, have a long service life, and are a common type of plastic pipe.

[0003] In the production process of PE hot melt pipes, raw material feeding is a crucial preliminary step. Currently, manual feeding is not only cumbersome to operate, but also suffers from efficiency bottlenecks. Although automatic feeding devices have been gradually put into use, existing technologies still have many shortcomings. When traditional feeding equipment is running, materials are very easy to clog at the feeding port, which seriously affects the continuity of feeding. Furthermore, it lacks flexible height and angle adjustment functions, making it difficult to reach materials at the bottom and corners of the hopper, resulting in raw material waste and increased production costs. Utility Model Content

[0004] This utility model proposes a material suction device for the production of PE hot melt pipes, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material suction device for the production of PE hot melt pipes, comprising a workbench, at least one set of negative pressure machines being provided at the top of the workbench, and a suction pipe being connected to one side of the multiple sets of negative pressure machines, a connecting plate being connected to the other end of the suction pipe, and a corrugated pipe being connected to one side of the connecting plate, the corrugated pipe and the suction pipe forming a sealed connection structure through the connecting plate, multiple sets of cylinders being provided on one side of the connecting plate, a material suction hood being sealed to the other end of the corrugated pipe, and a support frame being provided inside the material suction hood, a fixing block being connected to one end of the support frame, and a dual-axis motor being fixedly installed inside the fixing block, a first drive shaft being connected to the bottom output end of the dual-axis motor, and a first stirring blade being connected to the outside of the first drive shaft, and a mixing mechanism being connected to the other end of the negative pressure machine.

[0006] Preferably, the cylinder push end is configured with a ball head structure, the suction hood is provided with a collar, and the collar and the cylinder push end are rotatably connected.

[0007] Preferably, the top output end of the dual-axis motor is connected to the rotating shaft, and the rotating shaft is provided with spiral blades on the outside. The suction hood has an inlet, and the rotating shaft is located inside the inlet.

[0008] Preferably, the mixing mechanism includes a discharge pipe, one end of which passes through the workbench and is connected to a feeding trough. A motor is installed at the top of the workbench, and a second drive shaft is connected to the bottom output end of the motor.

[0009] Preferably, multiple sets of second stirring blades are symmetrically arranged on both sides of the second drive shaft, and the multiple sets of second stirring blades are arranged in an inclined structure of different sizes in the vertical direction.

[0010] Preferably, a conical mixing cylinder is connected to the bottom of the workbench, and a feeding trough is connected to the top of the conical mixing cylinder, with the second stirring blade disposed inside the conical mixing cylinder.

[0011] Preferably, the suction pipe is connected through a material box, and multiple sets of mounting brackets are provided at the bottom of the workbench.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Design of a dual-stirring anti-clogging structure: The dual-shaft motor inside the suction hood drives the first transmission shaft and the first stirring blade to rotate, performing preliminary stirring of the material to prevent the material from accumulating and clogging inside the suction hood. Spiral blades are set on the outside of the rotating shaft at the inlet. The material is driven to rise by the negative pressure machine, and the dual-shaft motor makes the spiral blades rotate to avoid the material getting stuck at the inlet and ensure a smooth suction process.

[0014] 2. The cylinder push end adopts a ball head structure, which forms a rotating connection with the collar of the suction hood. By using multiple sets of cylinders with different extension and retraction lengths, the height and angle of the suction hood can be flexibly adjusted, making it easier to reach the bottom and corners of the material box, reducing raw material waste and lowering production costs.

[0015] 3. After being sucked up, the material enters the conical mixing cylinder through the discharge pipe and the discharge chute. Through the stirring of the second stirring blade, the integrated design from material suction to mixing ensures that the PE raw materials are mixed evenly before hot melting, thereby improving the quality of pipe production.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-7 This utility model provides a technical solution: a suction device for the production of PE hot melt pipes, including a workbench 1. At least one set of negative pressure machines 2 is provided at the top of the workbench 1, and a suction pipe 3 is connected to one side of the multiple sets of negative pressure machines 2. The other end of the suction pipe 3 is connected to a connecting plate 5, and a corrugated pipe 6 is connected to one side of the connecting plate 5. The corrugated pipe 6 and the suction pipe 3 form a sealed connection structure through the connecting plate 5. Multiple sets of cylinders 7 are provided on one side of the connecting plate 5, and a suction hood 9 is sealed to the other end of the corrugated pipe 6. A support frame 10 is provided inside the suction hood 9. A fixing block 11 is connected to one end of the support frame 10, and a double cylinder is fixedly installed inside the fixing block 11. The dual-axis motor 12 has a first drive shaft 13 connected to its bottom output end, and a first stirring blade 14 connected to the outside of the first drive shaft 13. The other end of the negative pressure machine 2 is connected to a mixing mechanism. The pushing end of the cylinder 7 is set with a ball head structure. The suction hood 9 is provided with a collar 8, and the collar 8 and the pushing end of the cylinder 7 are rotatably connected. The top output end of the dual-axis motor 12 is connected to the rotating shaft 15, and a spiral blade 16 is provided on the outside of the rotating shaft 15. The suction hood 9 has an inlet 17, and the rotating shaft 15 is located inside the inlet 17. The suction pipe 3 is connected through the material box 4, and multiple sets of mounting brackets 24 are provided at the bottom of the workbench 1.

[0027] In practice, when performing material suction, the workbench 1 is first fixed to the production line using the mounting bracket 24 at the bottom to ensure stability. The suction pipe 3 is installed through the material box 4 for easy material suction. The multiple negative pressure machines 2 at the top of the workbench 1 are started, providing continuous negative pressure suction to the suction hood 9 through the suction pipe 3 and the corrugated pipe 6, forming the material suction power. While the material suction is in progress, the dual-shaft motor 12 inside the fixing block 11 is turned on, driving the first drive shaft 13 and the first stirring blade 14 to rotate, performing preliminary stirring of the material in the suction hood 9 to prevent material accumulation and blockage. When the material enters the suction pipe 3 through the inlet 17, the dual-shaft motor 12 can drive the spiral blade 16 to enter along with the rotating shaft 15. The rotating mechanism not only guides materials into the suction pipe 3 via a spiral pushing action, but also prevents the material from getting stuck at the inlet 17. When the relatively high material in the hopper 4 has been sucked up, the suction hood 9 is pushed by the cylinder 7 according to the accumulation position of the material in the hopper 4. This first proceeds to further suck up the material in the lower positions. When sucking up material in corners, the rotating function of the collar 8, combined with the varying extension lengths of multiple sets of cylinders 7, tilts the suction hood 9 to the bottom or corner of the hopper 4. Simultaneously, the vertical height is adjusted by the extension and retraction of the corrugated pipe 6 to ensure the suction port is close to the material, thus completing the suction of material at the bottom and corners of the hopper 4, reducing raw material waste and lowering production costs. These operations facilitate the material suction process.

[0028] Example 2

[0029] Reference Figure 1 , Figure 6 and Figure 7 This embodiment is an optimization based on embodiment 1. The mixing mechanism includes a discharge pipe 18, one end of which passes through the workbench 1 and is connected to a feeding trough 22. A motor 19 is installed at the top of the workbench 1, and the bottom output end of the motor 19 is connected to a second drive shaft 20. Multiple sets of second stirring blades 21 are symmetrically arranged on both sides of the second drive shaft 20, and the multiple sets of second stirring blades 21 are set to inclined structures of different sizes in the vertical direction. A conical mixing cylinder 23 is connected to the bottom of the workbench 1, and the top of the conical mixing cylinder 23 is correspondingly connected to the feeding trough 22. The second stirring blades 21 are arranged inside the conical mixing cylinder 23.

[0030] In practice, during the mixing process, the material in the suction pipe 3 falls through the negative pressure machine 2, the discharge pipe 18, and the discharge chute 22 into the conical mixing cylinder 23 at the bottom of the workbench 1. The discharge chute 22 is designed with an inclined slope to prevent material from accumulating inside. At this time, the motor 19 is turned on, driving the second drive shaft 20 and the two inclined second stirring blades 21 of different sizes on both sides to rotate. The second stirring blades 21, due to their different sizes, can fit against the inner wall of the conical mixing cylinder 23 from top to bottom, stirring the material in the conical mixing cylinder 23 in multiple directions. This causes the material to converge towards the center and tumble during the stirring process, achieving uniform mixing of the PE raw materials and preparing for the subsequent hot-melt process. Through the above work, the mixing of materials is facilitated.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
