Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to an online bagging and film coating equipment for steel-plastic pipes. Background Art

[0002] Steel-plastic pipe is a steel-plastic composite product that uses a steel pipe as a base, with a plastic layer melt-coated on its inner surface through a special process, and a plastic layer or other material anti-corrosion layer coated on its outer surface. This pipe combines the high strength, rigidity and impact resistance of steel pipes with the corrosion resistance, wear resistance, low fluid resistance and good hygienic properties of plastic pipes. It is a new type of pipeline material with excellent performance. In order to prevent damage to the steel-plastic pipe during transportation, an annular bag will be put on the outer surface of the steel-plastic pipe before transportation to protect the steel-plastic pipe. Usually, a bagging machine is used to bag it, but the bagging machine in the existing technology is relatively cumbersome for fixing and disassembling the steel-plastic pipe, resulting in low bagging efficiency.

[0021] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0022] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0023] This embodiment provides a steel-plastic pipe online bagging and film coating equipment, referring to Figures 1 to 5 , including a frame 1, a drawstring bagging mechanism 2 slidably connected to the top of the frame 1, a supporting mechanism for supporting the steel-plastic tube, a bag opening mechanism 4 for opening the annular bag, and a pressing mechanism 5. The bag opening mechanism 4 and the pressing mechanism 5 are respectively arranged at both ends of the supporting mechanism, wherein the bag opening mechanism 4 is provided with a positioning hole 41 at one end close to the supporting mechanism, and the steel-plastic tube can pass through the positioning hole 41 and enter the bag opening mechanism 4. The pressing mechanism 5 includes a telescopic pressing component 51 and an abutment 52. The telescopic end of the telescopic pressing component 51 is connected to the The abutment 52 and the telescopic pressing assembly 51 are used to drive the abutment 52 to move repeatedly along the axial direction of the steel-plastic pipe so that the abutment 52 is pressed against or separated from one end of the steel-plastic pipe. When the abutment 52 is pressed against one end of the steel-plastic pipe, the steel-plastic pipe is fixed on the bagging mechanism 4 to ensure the stability of the steel-plastic pipe during bagging. When the abutment 52 is separated from one end of the steel-plastic pipe, the operator can easily remove the steel-plastic pipe from the bagging mechanism 4, which is convenient for replacing the steel-plastic pipe, thereby improving the bagging efficiency.

[0024] In this embodiment, the abutment member 52 is tapered, and the cross-sectional area of the abutment member 52 gradually decreases toward the direction approaching the steel-plastic pipe, so that the abutment member 52 can adapt to steel-plastic pipes of different sizes.

[0025] In this embodiment, the telescopic pressing assembly 51 is configured as a telescopic air cylinder or a telescopic hydraulic cylinder.

[0026] In this embodiment, the bag opening mechanism 4 includes a bag opening cylinder 42. A positioning hole 41 is provided at one end of the bag opening cylinder 42 near the support mechanism. During operation, an operator generally manually inserts the annular belt onto the bag opening cylinder 42 and pulls the annular bag. During this process, the bag opening cylinder 42 can expand the annular bag, thereby allowing the annular belt to be smoothly inserted into the steel-plastic pipe. Furthermore, to facilitate the insertion of the annular belt onto the bag opening cylinder 42, a guide portion 43 is provided at the end of the bag opening cylinder 42 away from the support mechanism. The guide portion 43 is used to guide the annular bag into the bag opening cylinder 42.

[0027] Preferably, the guide portion 43 is tapered, and the cross-sectional area of the guide portion 43 gradually decreases in a direction away from the bag tube 42 .

[0028] In this embodiment, the bag opening tube 42 is provided with an observation port 44 connected to the positioning hole 41 , so that the operator can observe whether the steel-plastic pipe has smoothly entered the positioning hole 41 .

[0029] In this embodiment, the drawstring bagging mechanism 2 includes a workbench 21 and a bag clamping structure 22 positioned on the workbench 21 for clamping the annular bag. The top of the frame 1 is provided with at least one slide rail 11, and the bottom of the workbench 21 is provided with a sliding member 23 that is slidably connected to the slide rail 11. Specifically, the slide rail 11 is provided with a slide groove extending axially along the steel-plastic pipe, and the slide member 23 is slidably embedded in the slide groove to ensure that the workbench 21 can slide on the frame 1.

[0030] In this embodiment, the bag clamping structure 22 includes a bag clamping fixed block 221, a splint 222 movably connected to the inner side of the bag clamping fixed block 221, and a driving assembly for driving the splint 222 to move closer to or away from the bag clamping fixed block 221. The bag clamping fixed block 221 has a through hole 223 that allows the steel-plastic pipe to pass through. During operation, the operator places the annular bag between the bag clamping fixed block 221 and the splint 222, and then drives the splint 222 to move closer to the bag clamping fixed block 221 through the driving assembly to clamp the annular bag, or drives the splint 222 away from the bag clamping fixed block 221 through the driving assembly to loosen the annular bag. The driving assembly here is configured as a linear motor or a cylinder, which drives the splint 222 to move.

[0031] In this embodiment, the supporting mechanism includes multiple supporting assemblies 3, which are arranged at intervals along the axial direction of the steel-plastic pipe. The supporting assemblies 3 include a support platform 31 and rollers 32 rotatably connected to the support platform 31. In addition, the diameter of the rollers 32 gradually decreases from both ends to the middle, ensuring that the steel-plastic pipe can be stably placed on the multiple rollers 32.

[0032] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
