Description

Technical Field

[0001] The invention relates to the technical field of electric cabinet transportation, and in particular to an electric cabinet packaging method. Background Art

[0002] During the packaging, transportation and storage of electrical cabinet products, there are high requirements for waterproofing and moisture-proofing. The traditional packaging method is to lay a rain cloth on the electrical cabinet packaging and place a desiccant inside the packaging to ensure the waterproofing and moisture-proofing performance of the packaging. However, since moisture in the air will enter the packaging through the packaging gap during transportation and storage, the placed desiccant will gradually become ineffective over time, and the waterproofing and moisture-proofing performance of traditional packaging is difficult to meet the packaging, storage and transportation requirements of electrical cabinet products. Summary of the invention

[0003] Based on the above description, the present invention provides an electric cabinet packaging method to solve the problems raised in the above background technology.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: A method for packaging an electric cabinet comprises the following steps: S1. Place the electric cabinet on the base, use the cut first part of the membrane material to wrap the side of the electric cabinet horizontally, and then glue or heat-seal the end of the membrane material; S2. Lay the electric cabinet down so that its side contacts the base, and use the cut second portion of the membrane material to transversely wrap the electric cabinet in one circle, glue or heat-seal the connection between the two portions of the membrane material, glue or heat-seal the end covering portion of the second portion of the membrane material, and leave an air extraction port; S3. After vacuuming the gap between the membrane material and the electric cabinet at the air extraction port, the air extraction port is sealed by gluing or hot-melting; S4. Put the electrical cabinet into the corrugated paper box and seal it with tape; S5. Put the corrugated cardboard box into the wooden box and seal it.

[0005] Based on the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the length, width and height of the electric cabinet are defined as X, Y and Z respectively. The length of the first part of the membrane material in S1 is 2X+2Y+a, and the width is Z+b. The length of the second part of the membrane material in S2 is 2Z+2Y+a, and the width is Y+b.

[0007] Furthermore, the lengths of a and b are 20-50 mm.

[0008] Furthermore, the top corners of the electric cabinet are wrapped with foam blocks, and the foam blocks abut against the inner walls of the corrugated box.

[0009] Furthermore, the gap between the electric cabinet and the corrugated box is filled with pearl cotton.

[0010] Furthermore, the wooden box includes a bottom plate, a top plate, a first plate, and a second plate. The steps of installing the electric cabinet into the wooden pile are as follows: S6. Align the electric cabinet and place it at the center of the base plate; S7, placing the first plate and the second plate as the long side and the short side respectively against the electrical cabinet and splicing them into a rectangular frame, and then fixing the rectangular frame with a nail gun; S8, stacking a plurality of rectangular frames in sequence on top of the rectangular frame to cover the side of the electric cabinet; S9. Place the top plate cover on the top surface of the electric cabinet and splice it with the topmost rectangular frame, and finally fix it with a nail gun.

[0011] Furthermore, a connecting strip is vertically attached to the outside of the rectangular frame.

[0012] Furthermore, the connecting strip and the wooden box are fixed using a nail gun.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This solution uses a two-step wrapping method of the first part of the membrane material and the second part of the membrane material. By setting the overlapping and redundant lengths (lengths of a and b), it ensures that the membrane material can fit closely to each surface of the electric cabinet, enhancing the stability of the membrane structure packaging. Wrapping the corrugated cardboard box and building the wooden box in turn on the outside has good sealing and shockproof and anti-collision effects, and is low in cost. The entire packaging process is simple to operate, which reduces the difficulty of operation and the error rate, and facilitates standardization. The packaged electric cabinet meets the requirements of waterproof and moisture-proof packaging for long-term transportation and storage of electric cabinet products.

[0020] like Figure 3 As shown, the housing of the electric cabinet 1 is a rectangular structure. This solution provides a packaging method for the electric cabinet 1, comprising the following steps: S1. Place the electric cabinet 1 on the base. The base has any shape and is smaller than the bottom surface of the electric cabinet 1. When the electric cabinet 1 is placed on the base, the outer circle of the bottom of the electric cabinet 1 is exposed outside the base. Use the cut first part of the membrane material to wrap the side of the electric cabinet 1 horizontally, that is, cover the front, back, left and right sides of the electric cabinet 1, and then glue or heat-seal the end covering part of the membrane material.

[0021] In order to ensure that the first part can completely wrap the side of the electric cabinet 1, the length, width and height of the electric cabinet 1 are defined as X, Y and Z respectively. The length of the first part of the membrane material is 2X+2Y+a, and the width is Z+b, that is, a is the overlapping distance after the first part of the membrane material covers the four horizontal surfaces, and b is the length difference after the membrane material covers the side.

[0022] S2. Lay the electric cabinet 1 down so that its side contacts the base, that is, the first part of the membrane material contacts the base. Use the cut second part of the membrane material to wrap the electric cabinet 1 horizontally, covering the top, front, back, and bottom of the electric cabinet 1. The length of the second part of the membrane material is 2Z+2Y+a, and the width is Y+b. Similarly, a is the overlapping distance after the second part of the membrane material covers the four surfaces, and b is the redundant length after the membrane material covers the original top surface.

[0023] The second part of the membrane material needs to wrap the first part of the membrane material at the original top and bottom of the electric cabinet 1, and the first part of the membrane material with a length of b needs to be attached to the top or bottom surface, and then the second part of the membrane material is used to cover and press the membrane material with a length of b. The redundant length is used to improve the stability of the covering. The two parts of the membrane material are glued or hot-melted at the connection, and the end covering part of the second part of the membrane material is glued or hot-melted and an exhaust port is left. At this time, the first part and the second part of the membrane material are bonded to form a membrane box with an exhaust port.

[0024] S3. The gap between the membrane material and the electric cabinet 1 is evacuated at the air extraction port to exhaust the air inside, so that the touch box body is close to the outer wall of the electric cabinet 1, and then the air extraction port is sealed by gluing or hot welding, so that a membrane shell close to the electric cabinet 1 is formed. The membrane material is a waterproof material. The membrane material can be a heat shrink film.

[0025] S4, put the electric cabinet 1 into the corrugated paper box 2 and seal it with tape. Here, the foam block 3 is used to fill the gap between the electric cabinet 1 and the corrugated paper box 2. At least 18 corners of the electric cabinet are wrapped with foam blocks 3. When the electric cabinet 1 with the foam blocks 3 is inserted into the corrugated paper box 2, the foam blocks 3 fit the inner walls of the corrugated paper box 2. Fill the gaps without the foam blocks 3 with pearl cotton.

[0026] S5. Put the corrugated paper box 2 into the wooden box and seal it.

[0027] In one embodiment, Figure 1 , Figure 2As shown, the wooden box is a spliced ​​structure, including a bottom plate 4, a top plate 5, a first plate 6, and a second plate 7. The process of loading the corrugated box 2 into the wooden box is actually to splice and install the wooden box externally, including the following steps: S6. Align the electric cabinet 1 and place it at the center of the bottom plate 4 . The length and width of the bottom plate 4 must exceed those of the electric cabinet 1 .

[0028] S7. Place the first plate 6 and the second plate 7 as the long side and the short side respectively against the electric cabinet 1, and splice them into a rectangular frame that surrounds the side of the electric cabinet 1, and then use a nail gun to fix the rectangular frame. When the second plate 7 is the same length as the side of the electric cabinet 1, the length of the first plate 6 needs to exceed the corresponding side of the electric cabinet 1, and the excess distance is the thickness of the two second plates 7, so that the rectangular frame fits tightly with the corrugated box 2. When the first plate 6 is the same length as the side of the electric cabinet 1, the second plate 7 needs to exceed the corresponding distance.

[0029] S8. Stack several rectangular frames in sequence on top of the rectangular frame to cover the side surfaces of the electric cabinet 1 , and the stacked rectangular frames are just flush with the top surface of the electric cabinet 1 .

[0030] S9, the top plate 5 is placed on the top surface of the electric cabinet 1, covering and splicing with the topmost rectangular frame, and finally fixed with a nail gun, at this time, a wooden box structure that is tightly attached to the corrugated cardboard is formed. Correspondingly, a connecting strip 8 is vertically attached to the outside of the rectangular frame, and the connecting strip 8 is fixed to the wooden box with a nail gun, and the connecting strip 8 makes the rectangular frames of different layers form an overall fixed structure.

[0031] Preferably, the lengths of a and b are 20-50 mm.
