Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene pipe production equipment, and in particular to an automatic feeding device for the production of ultra-high molecular weight polyethylene pipes. Background Technology

[0002] In the production of ultra-high molecular weight polyethylene (UHMWPE) pipes, the precise proportioning of raw materials and efficient feeding are crucial for ensuring product quality and production efficiency. UHMWPE pipes, due to their excellent wear resistance, corrosion resistance, high strength, and good self-lubricating properties, are widely used in various industrial fields such as mining, chemical, power, and dredging. However, the production process demands extremely high precision in the proportioning of raw materials; even slight differences in different raw materials can significantly affect the performance of the final product. Currently, the traditional feeding method commonly used in the industry involves pre-weighing and mixing all required raw materials according to a predetermined ratio before production, and then feeding them into the production equipment all at once. While this method ensures the accuracy of the raw material proportioning to a certain extent, it has significant limitations. On the one hand, the tedious batching process required before each production run not only increases labor costs and time consumption but also makes it prone to errors due to human factors, affecting the consistency of product quality. On the other hand, for companies that frequently change production formulas or conduct small-batch trials, this pre-batching method undoubtedly increases production preparation time and costs, reducing production flexibility and efficiency.

[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 Figures 1-7 As shown, an automatic feeding device for the production of ultra-high molecular weight polyethylene pipes includes a storage component 1 and a discharge component 2 fixedly connected. The discharge component 2 is located below the storage component 1. The discharge component 2 has a conveying channel formed inside to transport raw materials along a preset path, and the top of the discharge component 2 is open to form a receiving cavity, which is connected to the conveying channel. The storage component 1 includes a support frame 11, and a through-type placement groove 12 is provided on the support frame 11. The placement groove 12 is provided with N detachable storage parts, and N limiting screws 13 are provided on one side of the support frame 11, where N ≥ 1. The limiting screws 13 are matched with the storage parts one by one, and the free end of the limiting screw 13 passes through the support frame 11 and is screwed onto the storage part. A cavity for storing raw materials is formed on the storage part, and the bottom of the storage part is open to form a first discharge hole 18.

[0024] With the above technical solution, before using the device, the storage part is placed in the placement groove 12 on the support frame 11. After the storage part is placed, the limiting screw 13 is placed on one side of the support frame 11, and one end of the limiting screw 13 is passed through the outside of the support frame 11. The free end of the limiting screw 13 is screwed into the storage part to complete the fixing of the storage part. After the storage part is fixed, the required number of storage parts are fixed on the support frame 11 according to the above steps. After all the storage parts are fixed, different types of raw materials are placed in each storage part to store different raw materials separately. When producing polyethylene pipes, different raw materials are discharged through the storage part and the receiving cavity on the discharge part 2 receives the raw materials discharged from the storage part, so that the raw materials are mixed. After the raw materials are mixed, the mixed raw materials are discharged through the first discharge hole 18 on the storage part to carry out the subsequent production of polyethylene pipes.

[0025] Specifically, in one embodiment, regarding the aforementioned discharge component 2, as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the discharge component 2 includes a guide cover 21, a receiving cavity is formed on the top of the guide cover 21, and a discharge pipe 24 is fixedly connected to the bottom of the guide cover 21. The circumferential surface of the discharge pipe 24 is open to form a second discharge hole 23.

[0026] In this embodiment, after the raw material is discharged from the storage section, it is received by the receiving cavity on the guide cover 21 and guided by the guide cover 21 to be transported to the discharge pipe 24. Finally, the mixed raw material is discharged through the second discharge hole 23 on the discharge pipe 24.

[0027] After the raw materials fall into the receiving cavity on the guide cover 21, in order to improve the uniformity of the raw material mixing, such as Figure 1 , Figure 2 and Figure 5 As shown, multiple material distribution rods 22 are fixedly connected inside the receiving chamber. A gap is formed between two adjacent material distribution rods 22 to allow raw materials to pass through. An inclined surface is formed at the bottom of the receiving chamber. The horizontal height of the inclined surface on the side near the discharge pipe 24 is lower than the horizontal height on the other side. A stirring rod 26 is rotatably connected inside the discharge pipe 24.

[0028] In this embodiment, the material receiving cavity on the material guide cover 21 supports the material distribution rod 22. The material receiving cavity on the material guide cover 21 receives the raw material, and the material distribution rod 22 cooperates with it to make the raw material more fully mixed when the raw material is sliding and conveyed. After the raw material is mixed, it is conveyed to the inside of the discharge pipe 24. The stirring rod 26 rotates in the discharge pipe 24 to further improve the uniformity of the raw material mixing. After the raw material is fully mixed, it is discharged through the second discharge hole 23 on the discharge pipe 24.

[0029] In addition, regarding how the stirring rod 26 rotates in this utility model, as follows: Figures 5-7 As shown, a second motor 25 is fixedly connected to the bottom of the discharge pipe 24, and the output end of the second motor 25 is connected to the stirring rod 26.

[0030] In this embodiment, after the raw material is conveyed into the discharge pipe 24, the second motor 25 operates, causing the stirring rod 26 to rotate. The stirring rod 26 stirs the raw material inside the discharge pipe 24, making the raw material more thoroughly mixed.

[0031] Specifically, in one embodiment, regarding the aforementioned storage section, as... Figures 1-4 As shown, the storage section includes a storage bin 14, a discharge pipe 15 is rotatably connected to the bottom of the storage bin 14, an auger 17 is rotatably connected between the bottom of the discharge pipe 15 and the storage bin 14, and a first discharge hole 18 is opened on the circumferential surface of the discharge pipe 15.

[0032] In this embodiment, after the raw material is added into the storage tank 14, the screw conveyor 17 rotates inside the discharge pipe 15 and the storage tank 14 to transport the raw material inside the storage tank 14 to the discharge pipe 15, and finally discharges the raw material through the first discharge hole 18.

[0033] In addition, regarding how the auger 17 rotates in this utility model, as follows: Figures 1-4 As shown, a first motor 16 is fixedly connected to the bottom of the discharge pipe 15, and the output end of the first motor 16 is connected to the auger 17.

[0034] In this embodiment, the first motor 16 operates, causing the auger 17 to rotate.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
