Abstract

This utility model proposes a material feeding device for pipe coating, specifically relating to the technical field of material feeding devices. It includes a frame, a sliding feeding assembly mounted on top of the frame, and a sliding loading assembly mounted on the frame and below the sliding feeding assembly. A steel pipe clamping rotating assembly is provided on one side of the frame for clamping the pipe and cooperating with the sliding loading assembly. The sliding feeding assembly allows the material to be evenly added to the loading assembly via sliding. The loading assembly allows the loading rod to pass through the steel pipe clamping rotating assembly and move into the steel pipe via sliding.

The poured material cooperates with the rotating steel pipe to achieve even pouring, resulting in a relatively uniform material thickness inside the steel pipe. This material feeding method results in good uniformity after material coating.

Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for pipe coating. Background Technology

[0002] Inner and outer polyethylene coated steel pipes are composite steel pipes made by hot-melting polyethylene powder to coat the inner and outer walls of the steel pipe. The steel pipe is preheated to make it rotate. When coating the inner wall, the polyethylene powder is poured onto the inner wall of the steel pipe.

[0003] The current method of pouring polyethylene powder usually involves manual loading, which makes it difficult to control the amount of polyethylene powder being filled and to ensure the thickness of the coating layer. If the coating layer is too thick, it will waste polyethylene powder raw materials. In addition, the dust generated during manual operation when pouring polyethylene powder will have a certain impact on human health. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example

[0026] refer to Figure 1-6 A pipe coating feeding device includes a frame 1, a sliding feeding assembly 3 disposed on the top of the frame 1, and a sliding feeding assembly 2 disposed on the frame 1 and located below the sliding feeding assembly 3. A steel pipe clamping rotating assembly 4 for clamping a pipe 323 and cooperating with the sliding feeding assembly 2 is provided on one side of the frame 1. The sliding feeding assembly 2 includes a first sliding carriage 21, two rotating parts 22 disposed on the top of the first sliding carriage 21, and a feeding assembly connected to the output flange of the rotating parts 22. The feeding rod 23 has a storage trough 24. The other side of the frame 1 is provided with a first drive assembly 5 for driving the first sliding cart 21. The sliding feeding assembly 3 includes a second sliding cart 31 disposed on the top of the frame 1, a spiral conveyor 32 disposed on the top of the second sliding cart 31, and a lifting feeding component 33 connected to the output end of the spiral conveyor 32 and cooperating with the storage trough 24. The other side of the top of the frame 1 is provided with a second drive assembly 6 for driving the second sliding cart 31.

[0027] The sliding feeding component 3 can evenly add raw materials to the sliding feeding component 2 by sliding. The sliding feeding component 2 can slide the feeding rod 23 through the steel pipe clamping rotating component 4 and move into the steel pipe. At the same time, the rotating component 22 makes the feeding pipe rotate, thereby completing the pouring of raw materials. The poured raw materials will cooperate with the rotating steel pipe to complete the even pouring of raw materials, so that the thickness of raw materials in the steel pipe is relatively uniform. This raw material feeding method not only has good uniformity after the raw material is coated, but also is easy to operate and has a high degree of automation.

[0028] In this embodiment, the spiral conveyor 32 can transport the raw material to the lifting member 331 feeding member, and the lifting member 33 can add the raw material into the storage tank 24.

[0029] In this embodiment, the first drive component 5 can drive the first sliding carriage 21 to perform linear reciprocating sliding work, while the second drive component 6 can drive the second sliding carriage 31 to perform linear reciprocating sliding work, thereby ensuring the operation of raw material feeding and material loading.

[0030] like Figure 2 As shown, the rotating component 22 includes two L-shaped brackets 221 disposed on the top of the first sliding carriage 21 and used for mounting the first drive motor 222, and a rotating rod 223 connected to the first drive motor 222 via a coupling. The top of the first sliding carriage 21 is provided with two first bearing seats 224 for the rotating rod 223 to pass through and cooperate with the rotating rod 223.

[0031] The first drive motor 222 is configured to drive the rotating rod 223 to rotate via a coupling. The rotating rod 223 will synchronously drive the feeding rod 23 to rotate. The rotating rod 223 will cause the raw material located inside the storage tank 24 to be poured onto the inner wall of the steel pipe, ensuring the feeding of raw materials.

[0032] In this embodiment, the first bearing seat 224 can support and assist the rotation of the rotating rod 223, thereby making the rotation of the rotating rod 223 more precise.

[0033] In this embodiment, the L-frame 221 provides a basis for the installation of the first drive motor 222. The L-frame 221 and the first drive motor 222 are installed using screws 73 or other fixing methods.

[0034] like Figure 2 As shown, the first drive assembly 5 includes a mounting plate 51 disposed on the other side of the frame 1, a second drive motor 52 disposed on the mounting plate 51, and a drive wheel 53 connected to the output end of the second drive motor 52. A second bearing seat 54 connected to the drive wheel 53 is disposed on the top of the mounting plate 51 and on one side of the drive wheel 53. A driven wheel 55 is disposed on the other side of the frame 1. A transmission belt 56 is disposed on the outer surface of the driven wheel 55 and the drive wheel 53.

[0035] The second drive motor 52 can drive the drive wheel 53 to rotate, and the rotating drive wheel 53 will drive the driven wheel 55 to rotate through the transmission belt 56. At the same time, the rotating belt will synchronously drive the first pulley cart to perform linear motion, thereby ensuring the feeding operation.

[0036] In this embodiment, preferably, a plurality of first protrusions are evenly provided on the inner side of the transmission belt 56, and the driving wheel 53 and the driven wheel 55 are both provided with second protrusions that mesh with the first protrusions.

[0037] like Figure 6 As shown, the top of the first sliding carriage 21 is provided with a fixing member 7 for fixing the transmission belt 56. The fixing member 7 includes a concave plate 71 disposed on the top of the first sliding carriage 21 and a convex plate 72 disposed on the top of the concave plate 71 and used to squeeze the transmission belt 56. Both the concave plate 71 and the convex plate 72 are provided with a plurality of screws 73 for fixing the convex plate 72 and the concave plate 71.

[0038] The fixing part 7 can connect the moving part of the transmission belt 56 to the top of the first sliding carriage 21, so that the first sliding carriage 21 can move synchronously with the movement of the transmission belt 56, ensuring the sliding operation of the first sliding carriage 21 itself.

[0039] In this embodiment, the concave plate 71 is provided to place one end of the transmission belt 56, while the convex plate 72 is provided to squeeze the transmission belt 56 and fix it with screws 73, thereby ensuring the stability of the transmission belt 56 after it is fixed.

[0040] As shown in the figure, the structure of the second driving component 6 is the same as that of the first driving component 5.

[0041] like Figure 3 As shown, the spiral conveyor 32 includes two mounting brackets 321 disposed on the top of the second sliding carriage 31, and a third drive motor 322 disposed on the mounting brackets 321. A pipe 323 is disposed on one side of the mounting brackets 321. A spiral component 324 connected to the output end of the third drive motor 322 is disposed inside the pipe 323. A material cylinder 325 is disposed on the top of the pipe 323, and a discharge pipe 326 is disposed below one side of the pipe 323.

[0042] like Figure 4 As shown, the lifting and feeding component 33 includes a lifting component 331 disposed at the bottom of the second sliding car 31, and a rod 332 connected to the output end of the lifting component 331. Two connecting blocks 333 are disposed on one side of the rod 332, and a sleeve 334 is disposed on one side of the two connecting blocks 333. One end of the sleeve 334 is sleeved with the discharge pipe 326, and the other end is tapered.

[0043] The lifting component 331 can drive the rod 332, two connecting blocks 333 and two sleeves 334 to move up or down synchronously. The two sleeves 334 moving down synchronously will reduce the distance between the sleeve end and the storage tank 24, ensuring accurate material feeding. The two sleeves 334 moving up will move away from the storage tank 24.

[0044] In this embodiment, the lifting component 331 includes a cylinder.

[0045] like Figure 5 As shown, the steel pipe clamping rotating assembly 4 includes a fourth drive motor 41 disposed on one side of the top of the frame 1, and a fixed shaft 42 disposed on the frame 1 and connected to the frame 1. A clamping end 44 is rotatably connected to one side of the fixed shaft 42. A drive gear end 43 is connected to the output end of the fourth drive motor 41. A driven gear end 45 is disposed on the outer surface of the fixed shaft 42. A transmission chain 46 is disposed between the drive gear end 43 and the driven gear end 45. A feeding groove 47 for the feeding rod 23 to pass through is provided on both the fixed shaft 42 and the clamping end 44.

[0046] The fourth drive motor 41 can drive the drive gear end 43, the transmission chain 46 and the driven gear end 45 to rotate. The rotating driven gear will drive the clamping end 44 to rotate, thereby completing the rotation of the steel pipe.

[0047] In this embodiment, the lower end face of the frame 1 is provided with a collection plate 8 for collecting raw materials;

[0048] In this embodiment, the rotation structure between the fixed shaft 42 and the clamping end 44 can be a bearing.

[0049] Working principle:

[0050] First, the staff uses an external feeding device to transport the raw materials into the hopper. After the raw materials are transported, the lifting component 331 will drive the rod 332, two connecting blocks 333, and two sleeves 334 to move downwards synchronously. The two sleeves 334 moving downwards synchronously will reduce the distance between the sleeve end and the storage trough 24. At the same time, the second drive assembly 6 can drive the second sliding trolley to move. During the movement of the second sliding trolley, the third drive motor 322 will drive the screw component 324 to rotate. The rotating screw component 324 will transport the raw materials that fall from the cylinder 325 into the pipe 323. The transported raw materials will enter the discharge pipe 326 and fall into the storage trough 24 through the sleeves 334. After the raw materials are added, the lifting component 331 will move downwards. 1. The two sleeves 334 will be reset. Then, the second drive motor 52 will drive the drive wheel 53 to rotate. The rotating drive wheel 53 will drive the driven wheel 55 to rotate through the transmission belt 56. At the same time, the rotating belt will drive the first pulley to move linearly. The linearly moving first pulley will cause the feeding rod 23 to pass through the steel pipe clamping rotating assembly 4 and move into the steel pipe. At the same time, the rotating part 22 will cause the feeding pipe to rotate, thereby completing the pouring of the raw material. The poured raw material will cooperate with the rotating steel pipe to complete the uniform pouring of the raw material, so that the thickness of the raw material in the steel pipe is relatively uniform. This raw material feeding method not only has good uniformity after the raw material is coated, but also is simple to operate and has a high degree of automation.

[0051] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0052] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
