Description

Technical Field

[0001] The utility model relates to the technical field related to thermal insulation pipe foaming, in particular to a foaming device for producing thermal insulation pipes. Background Art

[0002] During the production of the insulation pipe, in order to make the insulation pipe have insulation properties, foam of insulation material is injected between the outer sleeve and the inner sleeve of the insulation pipe. Although the existing foaming device can inject the foam of insulation material between the outer sleeve and the inner sleeve of the insulation pipe.

[0003] However, when performing foaming injection, in order to prevent the foaming of the insulation material from overflowing in the space formed by the outer sleeve and the inner sleeve at one end or the other end of the insulation pipe, a sealing flange must be installed before the foaming operation can be performed, and the sealing flange must be removed later so that the insulation pipe can undergo other processing, which is rather troublesome.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5A foaming device for producing an insulation pipe comprises a frame 1, which is rotatably connected to the frame 1 with a double-headed screw 2 through a bearing. The double-headed screw 2 can rotate at the frame 1, and two groups of baffles 3 are threadedly connected to the double-headed screw 2. Two groups of support plates 4 are fixedly connected to the frame 1. The top ends of the two groups of support plates 4 are used to place insulation pipes. The double-headed screw 2 is used to adjust the distance between the two groups of baffles 3. The two groups of baffles 3 can press and fit one end and the other end of the insulation pipe placed on the two groups of support plates 4, which can increase the placement stability of the insulation pipe and the stability of the foaming operation. At the same time, the two groups of baffles 3 can also block one end and the other end of the insulation pipe. Foaming can be performed without installing or removing the sealing flange, and the operation is relatively convenient.

[0024] In this embodiment, a support rod 5 is fixedly connected to the frame 1, a push rod 6 is installed on the support rod 5, and an injection head 7 is installed at the output end of the push rod 6. The injection head 7 is used to connect the external foaming conveying device, so that when the push rod 6 drives the injection head 7 to penetrate the outer sleeve of the insulation pipe, the foam of the insulation material can be injected into the space formed by the outer sleeve and the inner sleeve of the insulation pipe. A through groove 11 is processed at one end and the other end of the frame 1. Two groups of blocks 12 are slidably connected at the two groups of through grooves 11, and the multiple groups of blocks 12 are respectively fixed to the two groups of baffles 3. The block 12 can improve the lateral movement stability of the baffle 3. A motor 8 is installed on the frame 1. The model of the motor 8 is selected according to the actual work requirements. The output end of the motor 8 is connected to the double-headed screw 2. The two groups of support plates 4 are fixedly connected with a first rubber pad 9, which can increase the placement stability of the insulation pipe. The two groups of baffles 3 are fixedly connected with a second rubber pad 10 to improve the blocking stability of the insulation pipe and avoid foaming leakage at the joint between the baffle 3 and the insulation pipe. The four corners of the bottom end of the frame 1 are fixedly connected with a base 13.

[0025] The working principle of this embodiment is as follows: when in use, the insulation pipe is placed at the two groups of support plates 4. After placement, the motor 8 is connected to an external power supply and a driving device, and the motor 8 can rotate the double-headed screw 2, and the double-headed screw 2 can drive the two groups of baffles 3 to drive the corresponding second rubber pads 10 to fit tightly against one end and the other end of the insulation pipe respectively, so that the insulation pipe can be further fixed. While increasing the stability of the foaming operation, the space formed by the outer sleeve and the inner sleeve at one end and the other end of the insulation pipe will be blocked to prevent subsequent foaming from leaking at both ends. After the blocking is completed, the push rod 6 is connected to an external driving device and a power supply, and the injection head 7 is connected to an external foaming conveying device. The push rod 6 can drive the injection head 7 to penetrate the outer sleeve of the insulation pipe, and the foaming of the insulation material can be injected between the outer sleeve and the inner sleeve of the insulation pipe. After completion, the two groups of baffles 3 are cancelled from fitting the insulation pipe, and the insulation pipe can be removed, thereby completing the processing.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
