Abstract
Description
Technical Field
[0001] The utility model relates to the field of thermal insulation pipes, in particular to a thermal insulation pipe polyurethane waste collection device. Background Art
[0002] With the development of economy and urban construction, the application of thermal insulation pipes is increasing. In the process of manufacturing thermal insulation pipes, it is necessary to spray and wrap polyurethane on the outside of the steel pipe;
[0003] Since the polyurethane spraying of the insulation pipe is intermittent, in order to ensure that the thickness at both ends of the insulation pipe is the same as that in the middle, it is necessary to open and close the spray gun in advance during the spraying process. At this time, a large amount of polyurethane material will be spilled at the bottom of the spraying bin. The polyurethane material spilled at the bottom of the spraying bin will gather together to form an irregular polyurethane plate, which needs to be collected and cleaned;
[0004] The existing collection and cleaning methods often use manual cleaning. When cleaning, the equipment must be stopped first, and then it must be cleaned manually using tools. The cleaning work is very cumbersome, and after cleaning, the cleaned polyurethane is irregular, which takes up a lot of storage space. At the same time, these wastes are collected and then crushed and recycled using crushing equipment alone, which is very cumbersome and will increase the labor intensity of the operators.

[0007] Further optionally, the collecting assembly includes a collecting bin disposed below the spraying bin, and a storage box is slidably connected to the interior of the collecting bin.
[0008] Further optionally, the crushing assembly includes two crushing rollers rotatably supported on the left and right sides of the collecting bin and matched with each other, the shafts on the two crushing rollers extend to the outside of the collecting bin and rotate through gears, and one of the crushing rollers is connected to the control motor drive.
[0009] Further optionally, one end of the corresponding lead screw extends to the outside of the spray chamber and is drivingly connected to the output shaft of the drive motor, and the drive motor is connected to the side wall of the spray chamber through a bracket.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:
[0018] like Figure 1 , 2 As shown in Figure 3, a polyurethane waste collection device for insulation pipes includes a tugboat conveyor line 1 for spirally moving the insulation pipe 2 forward, a spraying bin 3 is arranged on the tugboat conveyor line 1, two lead screws 6 are rotatably supported above the bottom plate of the spraying bin 3, and a scraper plate 5 for cleaning polyurethane waste on the upper part of the bottom plate of the spraying bin 3 is slidably connected to the corresponding threads on the lead screws 6, a collecting component is arranged below the bottom plate of the spraying bin 3, and a drop opening is opened on the bottom plate of the spraying bin 3 at the end of the scraper plate 5 in the running direction, and a crushing component is installed at the drop opening.
[0019] like Figure 2 , 3 As shown, the collecting assembly includes a collecting bin 9 disposed below the spraying bin 3 , and a storage box 10 is slidably connected inside the collecting bin 9 .
[0020] like Figure 1, 3 As shown, the crushing assembly includes two crushing rollers 8 rotatably supported on the left and right sides of the collecting bin 9 and matched with each other. The shafts on the two crushing rollers 8 extend to the outside of the collecting bin 9 and rotate through gears 14. One of the crushing rollers 8 is drive-connected to the control motor 13.
[0021] like Figure 1 , 3 As shown, one end of the corresponding lead screw 6 extends to the outside of the spray chamber 3 and is driven and connected to the output shaft of the drive motor 7, and the drive motor 7 is connected to the side wall of the spray chamber 3 through a bracket.
[0022] like Figure 3 As shown, a downwardly inclined slide plate 12 is provided below the crushing roller 8, and the slide plate 12 is fixed to the side of the collecting bin 9 through a bracket.
[0023] like Figure 2 , 3 As shown, a handle 11 is provided on the outside of the storage box 10 for easy pulling.
[0024] The implementation principle of the polyurethane waste collection device for thermal insulation pipes in the embodiment of the present application is as follows:
[0025] When the conveyor belt 1 transports the steel pipe 2 to the entrance of the spraying bin, the spray gun 4 is started. At this time, the steel pipe will slowly move forward in a spiral. During the forward movement, the spray gun 4 will spray polyurethane onto the steel pipe 2. At the same time, some polyurethane waste begins to accumulate at the bottom of the spraying bin 3.
[0026] When there is waste at the bottom of the spraying bin 3, the corresponding driving motor 7 is started. When the driving motor 7 rotates, the lead screw 6 is driven to rotate synchronously, and the scraper plate 5 is driven to move forward. When moving, the waste at the bottom of the spraying bin 3 is pushed onto the crushing roller 8. After being pushed onto the crushing roller 8, the driving motor 7 is reversed to make the scraper plate 5 return to its original position to prepare for the next scraping work. At the same time, the control motor 13 is started. The output shaft of the control motor 13 drives the crushing roller 8 to rotate through the mutually meshing gears 14. During the rotation, the polyurethane waste pushed over will be crushed, and the crushed waste will fall from the lower part of the crushing roller 8 onto the slide plate 12, and at the same time slide into the storage box 10 in the collection bin 9;
[0027] When it is observed that there is a lot of crushed waste in the storage box 10, the handle 5 is pulled out to pull out the storage box 10, and then the polyurethane particles inside are cleaned out, thereby completing the waste collection and cleaning. The whole process is easy and labor-saving, and also reduces the labor intensity of the operator.
[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
