DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Embodiment 1:

[0030] Please see Figures 1-5 A polyethylene resin winding device for producing thermal insulation pipes includes a main body 1, a pipe 2, a positioning mechanism, and an auxiliary mechanism. The positioning mechanism includes a first motor 3, a lead screw 4, a sliding frame 5, a second motor 6, a rotating disk 7, and a clamping mechanism. The first motor 3 is fixedly installed inside the main body 1. The lead screw 4 is fixedly installed at both ends of the first motor 3 and threadedly engaged with the sliding frame 5. The sliding frame 5 is installed inside the main body 1 and slidably connected to the main body 1. The second motor 6 is fixedly installed on the sliding frame 5 and fixedly connected to the rotating disk 7. The rotating disk 7 is installed on the sliding frame 5 and rotatably connected to the sliding frame 5. The clamping mechanism includes an electric push rod 8, a first connecting rod 9, a second connecting rod 10, and a clamping plate 11. The electric push rod 8 is fixedly installed inside the rotating disk 7. The first connecting rod 9 is rotatably connected to the clamping plate 11 and the electric push rod 8, respectively. The second connecting rod 10 is rotatably connected to the clamping plate 11 and the rotating disk 7, respectively. The clamping plate 11 is connected to the pipe 2.

[0031] In this embodiment, the positioning mechanism includes a first motor 3, a lead screw 4, a sliding frame 5, a second motor 6, a rotating disk 7, and a clamping mechanism. In use, the first motor 3 drives the lead screw 4 to rotate, causing the sliding frame 5 installed inside the main body 1 to begin sliding in the main body 1. When the sliding frame 5 slides, the first limiting slider on the sliding frame 5 slides in the first limiting groove of the main body 1. Under the action of the second roller 18, the cooperation between the first groove 20 on the sliding frame 5 and the second roller 18 reduces friction when the sliding frame 5 moves, making the movement of the sliding frame 5 more stable. The second motor 6 and the rotating disk 7 installed on the sliding frame 5 move with the sliding frame 5, and then the pipe 2 is placed into the positioning groove of the main body 1. Subsequently, the first motor 3 rotates in the opposite direction, causing the sliding frame 5 to begin inserting into the main body 1, and the rotating disk 7 also enters the interior of the main body 1.

[0032] In this embodiment, the clamping mechanism includes an electric push rod 8, a first connecting rod 9, a second connecting rod 10, and a clamping plate 11. In use, the electric push rod 8 is driven, directly changing the position of the connecting plate 22 on the electric push rod 8, thereby changing the positions of the first connecting rod 9 and the second connecting rod 10. This causes the clamping plate 11 to clamp the inner wall of the pipe 2. Then, the second motor 6 drives the rotating disk 7 to rotate. When the rotating disk 7 rotates, the third roller 19 slides in the second sliding groove 21. Since the clamping plate 11 is in contact with the inner wall of the pipe 2, the pipe 2 begins to rotate in the positioning groove. Under the action of the first roller 17, the rotation of the pipe 2 becomes more stable.

[0033] In this embodiment, the auxiliary mechanism includes a third motor 12, a wrapping film 13, a driven member 14, an active member 15, and a spring 16. First, the wrapping film 13 is placed inside the main body 1. At this time, one end of the wrapping film 13 is inserted into the driven member 14, and the protrusion 26 on the wrapping film 13 directly enters the insertion groove 27 of the driven member 14. Then, the active member 15 is compressed, and the active member 15 compresses the spring 16. During this process, the second limiting slider 30 on the active member 15 slides in the second limiting groove 29 of the mounting sleeve 28. When the wrapping film 13 is placed into the main body 1, the compressed spring 16 pushes the active member 15 to contact the wrapping film 13. The third motor 12 drives the wrapping film 13 to rotate directly. Then, the plastic film on the wrapping film 13 is placed on the pipe 2. At this time, the third motor 12 and the second motor 6 rotate in coordination, and under the action of the first roller 17, the plastic film can be firmly wrapped on the pipe 2.

[0034] Example 2:

[0035] In summary, during use, the first motor 3 directly drives the lead screw 4 to rotate, causing the sliding frame 5 installed inside the main body 1 to begin sliding within the main body 1. As the sliding frame 5 slides, the first limiting slider on the sliding frame 5 slides within the first limiting groove of the main body 1. Furthermore, under the action of the second roller 18, the cooperation between the first groove 20 on the sliding frame 5 and the second roller 18 reduces friction during movement, making the movement of the sliding frame 5 more stable. Additionally, the second motor 6 and the rotating disk 7 installed on the sliding frame 5 move together with the sliding... The sliding frame 5 moves, and then the pipe 2 is placed into the positioning slot of the main body 1. Then the first motor 3 rotates in the reverse direction, causing the sliding frame 5 to begin inserting into the main body 1, and the rotating disk 7 also enters the interior of the main body 1. When the rotating disk 7 is positioned, the clamping mechanism starts to operate. At this time, the electric push rod 8 is driven, directly changing the position of the connecting plate 22 on the electric push rod 8, thereby changing the position of the first connecting rod 9 and the second connecting rod 10, so that the clamping plate 11 clamps the inner wall of the pipe 2. Then the second motor 6 drives the rotating disk 7 to rotate, and the rotating disk 7... During rotation, the third roller 19 slides in the second groove 21. Since the clamping plate 11 contacts the inner wall of the pipe 2, the pipe 2 begins to rotate in the positioning groove. Under the action of the first roller 17, the rotation of the pipe 2 becomes smoother. Then, plastic film is wrapped around the pipe 2. First, the wrapping piece 13 is placed inside the main body 1. Then, one end of the wrapping piece 13 is inserted into the driven member 14. The protrusion 26 on the wrapping piece 13 directly enters the insertion groove 27 of the driven member 14. Subsequently, the driving member 15 is compressed. The spring 16 is compressed, and during this process, the second limiting slider 30 on the active member 15 slides in the second limiting groove 29 of the mounting sleeve 28. When the wrapping member 13 is placed into the main body 1, the compressed spring 16 pushes the active member 15 to contact the wrapping member 13, and the third motor 12 drives the wrapping member 13 to rotate directly. Then the plastic film on the wrapping member 13 is placed on the pipe 2. At this time, the third motor 12 and the second motor 6 rotate together, and under the action of the first roller 17, the plastic film can be firmly wrapped on the pipe 2.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
