[0002] During the processing of water supply pipelines, the head end of the pipeline needs to be plugged after cutting, that is, the head end of the pipeline needs to be sealed. There are roughly two existing plugging methods: one is to manually seal the cut pipeline with a welding gun. However, this manual welding method is time-consuming and complicated to operate. Moreover, it is difficult to ensure the quality of the plug, that is, the sealing effect of the plug is difficult to ensure. After this water supply pipeline is put into use, water or other fluids will leak from the plug, which will reduce the service life of the water supply pipeline; the other is to design two pipeline production lines, one pipeline production line is used for cutting the pipeline, and the other pipeline production line is used for plugging the pipeline after cutting. However, this method requires the use of an overhead crane to transport the pipeline between the two pipeline production lines, which is complicated to operate and labor-intensive.

[0020] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0021] In this document, terms such as "upper, lower, left, right, inside, and outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also vary. Therefore, they cannot be understood as absolute limitations on the scope of protection. Moreover, relational terms such as "first" and "second" are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components. In addition, in the embodiments of the present invention, "above", "below", etc. include the numbers themselves.

[0022] The water supply pipe plugging device of this embodiment can plug the head end of the cut water supply pipe, and the operation process is fast and efficient, and can ensure that the cut surface of the water supply pipe after plugging is reliably sealed.

[0023] Reference Figure 1 and Figure 2 The water supply pipe plugging device of this embodiment includes a roller 1, a rubber supply hose 2, and a heating element 3. The roller 1 is provided with a groove 11 adapted to fit the wall of the water supply pipe 100. During the plugging operation, the head end wall of the water supply pipe 100 can be inserted into the groove 11, thereby using the roller 1 to compact the head end wall of the water supply pipe 100.

[0024] The roller 1 is provided at a first position at the head end of the water supply pipe 100, and the roller 1 rolls at the first position following the rotation of the water supply pipe 100, and the wall of the head end of the water supply pipe 100 is compacted by the rolling of the roller 1. Specifically, the water supply pipe 100 rotates with the assistance of an external force. For example, it can be rotated on a pipe making line for cutting the water supply pipe 100, so that the cutting and plugging of the water supply pipe 100 are completed on one pipe making line, eliminating the trouble of transporting the water supply pipe 100 and facilitating operation. In addition, a support member can be designed on the pipe making line, for example, a support rod is designed to support the roller 1, and the roller 1 is connected to the support rod in a rolling manner to ensure that the roller 1 can roll smoothly following the rotation of the water supply pipe 100.

[0025] The end of the glue supply hose 2 is provided with a glue outlet 21, which is oriented toward the second position of the head end of the water supply pipe 100, thereby providing glue to the head end of the water supply pipe 100 at the second position and sealing the head end of the water supply pipe 100 with glue.

[0026] The heating element 3 is used to heat the third position at the head end of the water supply pipe 100. Along the rotation direction of the water supply pipe 100, the third position, the second position, and the first position are arranged in sequence. That is, along the rotation direction of the water supply pipe 100, the heating element 3 at the third position, the rubber supply hose 2 at the second position, and the roller 1 at the first position are passed in sequence.

[0027] When the plugging device of this embodiment performs a plugging operation on the water supply pipe 100, the heating element 3 first heats the water supply pipe 100 to melt and soften it, and then the melted and softened water supply pipe 100 passes through the glue supply pipe 2, and the glue squeezed out from the glue outlet 21 of the glue supply pipe 2 contacts the melted and softened water supply pipe 100, and finally passes through the roller 1, and the glue is compacted and tightly fitted to the head end of the water supply pipe 100 under the action of the groove 11 of the roller 1, thereby realizing a fast, efficient, safe and reliable plugging operation of the water supply pipe 100.

[0028] In the specific implementation of this embodiment, the roller 1 is made of metal or ceramic to improve the compaction effect on the head end of the high-temperature melt-softened water supply pipe 100, and the roller 1 made of metal or ceramic has a long service life and can improve the durability of the entire plugging device.

[0029] Specifically, the depth of the groove 11 is designed to be 1 to 15 cm, and the width of the groove 11 is designed to be 0.5 to 100 cm, so as to be applicable to common specifications and sizes of the water supply pipe 100 and have a wide range of applications.

[0030] In the specific implementation of this embodiment, the rubber supply hose 2 is connected to a screw extruder (not shown) filled with rubber. During plugging, the rubber is extruded from the screw extruder into the rubber supply hose 2 and discharged from the rubber outlet 21 at the end of the rubber supply hose 2 to the head end of the water supply pipe 100. Specifically, the rubber is made of the same material as the water supply pipe 100, or has a higher purity and / or higher adhesion than the water supply pipe 100. This improves the plugging effect on the water supply pipe 100 and prevents the sealing effect from being affected by the use of poor quality rubber.

[0031] Specifically, the amount of glue used, and thus the discharge speed of the screw extruder, can be adjusted based on the wall thickness of the water supply pipe 100. When the wall thickness of the water supply pipe 100 is thicker, the discharge speed of the screw extruder is increased. Conversely, when the wall thickness of the water supply pipe 100 is thinner, the discharge speed of the screw extruder is reduced. For example, the discharge speed of the screw extruder is designed to be 5 to 1500 r / min to accommodate common water supply pipe 100 specifications and sizes, thus providing a wide range of applications.

[0032] In a specific implementation of this embodiment, the cross-section of the glue outlet 21 is designed to be circular or elliptical to improve the continuous uniformity of glue discharge, thereby ensuring consistent glue supply at all locations of the water supply pipe 100 and ensuring good consistency in the final plug sealing effect across the pipe diameter of the water supply pipe 100. Furthermore, the direction of the glue outlet 21 is tangent to the wall of the head end of the water supply pipe 100 to facilitate uniform distribution of glue at the head end of the water supply pipe 100.

[0033] In the specific implementation of this embodiment, the heating element 3 is an infrared heating lamp, and the heating temperature of the heating element 3 is 60~260℃ to meet the needs of water supply pipes 100 of different sizes or materials, so that the plugging device of this embodiment can seal the head ends of different water supply pipes 100.

[0034] Specifically, the distance between the heating element 3 and the head end of the water supply pipe 100 is 0.5 to 5 cm to meet the requirements of water supply pipes 100 of different sizes or materials. For example, a support member can be designed to support the heating element 3 and keep it 0.5 to 5 cm away from the head end of the water supply pipe 100.

[0035] In addition, according to the attached Figure 2 It can be seen from the display that the heating element 3 can cover a section of the diameter of the head end of the water supply pipe 100. In this way, a certain section of the head end pipe wall of the water supply pipe 100 can be heated to improve the efficiency of the plugging operation.

[0036] Take the DN630-1.0Mpa water supply pipe 100 as an example. When the cutting surface (head end) needs to be sealed, the attached Figure 2 In the display direction, the water supply pipe 100 starts to rotate counterclockwise with the assistance of an external force, and the temperature of the infrared heating tube is set to 205°C. The cut surface of the water supply pipe 100 heated and baked by the heating element 3 begins to melt; then, as the water supply pipe 100 rotates counterclockwise, the cut surface heated and melted by the heating element 3 reaches the glue outlet 21 of the glue supply hose 2, and the glue provided by the screw extruder is squeezed out from the glue outlet 21 and coated on the melted cut surface wall; then, as the water supply pipe 100 continues to rotate counterclockwise, As the water supply pipe 100 rotates, the molten cross-section coated with glue reaches the roller 1. Specifically, the groove width of the roller 1 is 15 mm. Under the pressure and coating of the roller 1 and its groove 11, the glue is tightly attached to the cross-section of the water supply pipe 100. In this way, as the water supply pipe 100 rotates, various cross-sections of the water supply pipe 100 can pass through the heating element 3, the glue supply hose 2 and the roller 1 in turn to complete the plug sealing at various cross-sections of the water supply pipe 100, thereby realizing a fast, efficient, safe and reliable plugging operation of the water supply pipe 100.
