Description

Technical Field

[0001] The invention relates to the technical field of garbage cans, in particular to the field of garbage can repair, and specifically refers to an embedded chain hot-melt repair method for a sanitation garbage can. Background Art

[0002] In daily life, community trash cans are always subject to violent dumping by sanitation vehicles and quality defects of some products, resulting in cracks and damage in the sanitation trash cans, which affects the quality and environment of the community. If they are replaced directly, the cost is high. Currently, they are generally repaired by gluing, but due to the presence of dust and sewage in the cracks, the bonding surface is prone to cracking after a period of time. There is an urgent need for a repair method that can repair cracks in trash cans. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a method for hot-melt repairing an embedded chain in a sanitation trash can, which is sturdy and durable, well sealed, beautiful in appearance, and economical.

[0004] The present invention is implemented through the following technical scheme, and provides a method for hot-melt repair of an embedded chain in a sanitation trash can, comprising the following steps: a. Clean the surface stains in the cracks of the trash can; b. Prepare a hot-melt steel wire according to the length of the crack, wherein the hot-melt steel wire comprises a serpentine welding portion, and both ends of the welding portion are connected with connecting portions, and the connecting portions are perpendicular to the plane where the welding portion is located; c. Insert the two connecting parts of the hot melt wire into the countersunk holes at the front ends of the two electrode columns of the hot melt gun respectively, and fit the welding part to the crack position; d. Press the switch of the hot melt gun to connect the two electrode columns to the positive and negative electrodes of the power supply respectively. The current flows through the hot melt wire to heat it. The welding part of the hot melt wire melts the surface of the trash can and is embedded in the trash can; e. Release the switch, wait for the hot melt position of the trash can to harden, take away the hot melt gun, and remove the connection part of the hot melt wire; f. Install multiple hot-melt steel wires along the length of the crack in sequence until the crack is completely repaired and grind the repaired position smooth.

[0005] As an optimization, an annular groove is provided at the connection position between the connection part and the welding part. In step e, the connection part is broken at the position of the annular groove by reciprocating the connection part, thereby removing the connection part of the hot-melt steel wire. The annular groove provided in this solution reduces the diameter of this position, so that the position can be broken by repeated bending, which facilitates the removal of the connection part.

[0006] As an optimization, a plastic ring is provided on the annular groove. In step d, due to the small diameter, large resistance, and high temperature at the position of the annular groove, the plastic ring melts and is embedded in the crack and the gap between the welding part and the trash can. In this solution, a plastic ring is sleeved on the annular groove. Due to the small diameter, large resistance, and high temperature at the position of the annular groove, the plastic ring will be melted into a liquid state and thus flow into the crack or the gap between the trash can and the welding part. Here, the gap refers to the area that is not covered in time above the welding part after the welding part is pressed into the trash can. The melted plastic ring fills part of this gap, thereby improving the connection strength.

[0007] As an optimization, the diameter of the hot-melt steel wire is 0.4 - 1.2 m, and the diameter at the position of the annular groove is 0.2 - 0.7 mm. Thus, a good connection effect is achieved.

[0008] As an optimization, the cross-section of the annular groove is triangular. Therefore, the bottom of the groove is a sharp angle, which is convenient for stress concentration and thus convenient for breaking.

[0009] As an optimization, the welding part includes a plurality of parallel straight parts, and adjacent straight parts are connected by an arc connecting part. When the welding part is attached to the crack position in step c, the straight part is perpendicular to the crack. The straight part in this solution is perpendicular to the crack, so the two sides of the crack are connected.

[0010] As an optimization, the length of the straight part at the end is 0.6 - 0.8 times the length of the other straight parts. Thus, the straight part at the end can also cross the crack position, and at the same time, the adjacent hot-melt steel wires can cross each other.

[0011] As an optimization, there are 5 straight parts provided.

[0012] As an optimization, an elastic conductive sheet for clamping the connecting part is provided in the counterbore at the front end of the electrode post. The elastic conductive sheet in this solution realizes conduction, and at the same time, it can be clamped after the connecting part is inserted into the counterbore. After the connecting part is embedded in the trash can, the connecting part can be pulled out of the counterbore.

[0013] As an optimization, a handle is provided on the hot-melt gun, and the switch is arranged on the handle. Thus, it is convenient for holding and operating.

[0014] The beneficial effects of the present invention are as follows: A method for inlaying a chain-type hot-melt repair in a sanitation trash can of the present invention realizes the connection and repair of the crack area by heating the hot-melt steel wire and embedding it in the crack area. The invention can well solve the problem of cracking and damage of sanitation trash cans, solve the sealing performance of the trash cans, prevent garbage overflow, prevent swill leakage, improve the appearance quality, save the use cost, and protect the environment.

[0016] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0017] like Figures 1 to 7 As shown, a chain-embedded hot-melt repair method for a sanitation trash can of the present invention uses a hot-melt steel wire and a hot-melt gun 11.

[0018] The diameter of the hot-melt steel wire must be smaller than the wall thickness of the trash can. The diameter of the hot-melt steel wire is 0.4-1.2m. It is formed by bending a steel wire. The hot-melt steel wire includes a serpentine welding part, which is located on a plane. The two ends of the welding part are connected with connecting parts 3, and the connecting part 3 is perpendicular to the plane where the welding part is located.

[0019] like Figure 1-3 As shown, the welding portion includes a plurality of parallel straight portions 1, and adjacent straight portions 1 are connected by arc-shaped connecting portions 2 to form a serpentine structure. The straight portion 1 at the end is slightly shorter, specifically, the length of the straight portion 1 at the end is 0.6-0.8 times the length of the remaining straight portions 1.

[0020] In this embodiment, there are 5 straight sections 1. Therefore, when installing two adjacent hot-melt steel wires, they can be installed like Figure 4 Crossover is achieved as shown.

[0021] like Figure 2 , 6As shown, an annular groove 4 is provided at the connection position between the connection part 3 and the welding part, and the diameter of the annular groove 4 is 0.2-0.7 mm, so that the diameter of this position becomes smaller, so that the position can be broken by repeated bending, which is convenient for removing the connection part. The cross section of the annular groove 4 is triangular, so the bottom of the groove is a sharp corner, which is convenient for stress concentration and thus easy to break.

[0022] A plastic ring 5 is provided on the annular groove 4. Since the smaller the metal cross-section, the greater the resistance, the annular groove has a small diameter, a large resistance and a high temperature, the plastic ring will melt into a liquid state and flow into the crack or the gap between the trash can and the welding part. The gap here refers to the area above the welding part that is not covered in time after the welding part is pressed into the trash can. The melted plastic ring fills part of the gap, thereby improving the connection strength.

[0023] The front end of the hot melt gun 11 is provided with two electrode columns 7 arranged side by side, and a countersunk hole is opened at the front end of the electrode column 7. The center distance between the countersunk holes of the two electrode columns 7 is equal to the distance between the two connecting parts 3. The hot melt gun 11 is provided with a handle 9, and a switch 10 is arranged on the handle 9. After pressing the switch, the two electrode columns 7 are respectively connected to the positive and negative poles of the power supply.

[0024] The countersunk hole at the front end of the electrode column 7 is provided with an elastic conductive sheet 8 for clamping the connection part 3. After the connection part 3 is inserted into the countersunk hole, the elastic conductive sheet 8 is elastically pressed against the side of the connection part 3, and the elastic conductive sheet realizes conductivity. At the same time, the connection part can be clamped after being inserted into the countersunk hole, and after the connection part is embedded in the trash can, the connection part can be pulled out of the countersunk hole.

[0025] A method for hot-melt repairing an embedded chain in a sanitation trash can, comprising the following steps: a. Clean the surface stains at the cracks 6 of the trash can; b. Prepare a hot-melt steel wire according to the length of the crack, wherein the hot-melt steel wire comprises a serpentine welding portion, and both ends of the welding portion are connected with connecting portions 3, and the connecting portions 3 are perpendicular to the plane where the welding portion is located; c. Insert the two connecting parts 3 of the hot melt steel wire into the countersunk holes at the front ends of the two electrode columns 7 of the hot melt gun 11 respectively, and fit the welding part to the crack position, with the straight part 1 perpendicular to the crack; d. Press the switch 10 of the hot melt gun 11 to connect the two electrode columns 7 to the positive and negative electrodes of the power supply respectively. The current flows through the hot melt wire to heat it. The welding part of the hot melt wire melts the surface of the trash can and is embedded in the trash can. Since the annular groove 4 has a small diameter, large resistance and high temperature, the plastic ring 5 is melted and embedded in the crack and the gap between the welding part and the trash can.

[0026] e. Release the switch 10, wait for the hot melt position of the trash can to harden, then take out the hot melt gun 11 and remove the connecting part 3 of the hot melt steel wire; specifically, break the connecting part 3 at the position of the annular groove 4 by bending the connecting part 3 back and forth, thereby removing the connecting part 3 of the hot melt steel wire.

[0027] f. Install multiple hot-melt steel wires along the length of the crack in sequence until the crack is completely repaired and grind the repaired position smooth.

[0028] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.
