Description

Technical fields:

[0001] This utility model relates to the field of thermal insulation pipe production and processing technology, and specifically to a thermal insulation pipe punching mechanism. Background technology:

[0002] Air conditioning insulation pipes are key components of air conditioning systems. Sleeving them over the outside of the ductwork provides insulation, shock protection, and ensures stable system operation while reducing energy consumption. However, air conditioning ducts often branch off laterally due to installation requirements, and these branches can intersect with adjacent components. Because the insulation pipe is a tubular structure, its installation path must closely follow the ductwork's direction. This can easily lead to interference at these intersections, hindering successful assembly.

[0003] To address this issue, the industry standard practice is to manually make an axial cut at one end of the insulation pipe after processing, using a knife to avoid adjacent components during assembly. However, traditional manual cutting has several drawbacks: firstly, it is inefficient and labor-intensive, severely restricting production; secondly, workers directly handle sharp tools, posing a high safety hazard; and thirdly, it requires high technical skills—simultaneously holding the tool, controlling the cutting path, fixing the insulation pipe, and avoiding deep cuts that could damage the pipe wall, resulting in high labor intensity and requiring intense concentration.

[0004] Chinese Patent Publication No. CN 211761828 U discloses a pipe-opening machine for air conditioning insulation pipes, including a frame and a guide groove. The guide groove has its opening facing upwards to allow the air conditioning insulation pipe to be inserted, and the groove cavity forms a guide cavity that restricts the air conditioning insulation pipe to only undergo axial sliding movement. A limiting part is arranged in the guide groove cavity to limit the sliding distance of the air conditioning insulation pipe. The pipe-opening machine also includes a power source arranged beside the guide groove. A cutting wheel for cutting the wall of the air conditioning insulation pipe is coaxially fixed to the output shaft of the power source. The wheel axle is perpendicular to the length direction of the guide groove. The cutting edge of the cutting wheel extends into the guide groove cavity from top to bottom, and the minimum distance between the cutting edge and the bottom surface of the guide groove is greater than the wall thickness of the air conditioning insulation pipe. This utility model can safely and reliably achieve rapid axial cutting of the end of the air conditioning insulation pipe while ensuring the accuracy of the cutting path and the efficiency of the cutting.

[0005] However, the above-mentioned patented solution requires the air conditioning insulation pipe to be cut and then transferred to a pipe opening machine for opening, which is cumbersome and inefficient.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a heat insulation pipe punching mechanism.

[0009] Furthermore, in the above technical solution, the material receiving module includes a first support frame and a second support frame that are suspended above the discharge hole in the middle of the frame and can be separated, a plurality of first rollers and second rollers arranged on the first support frame and the second support frame and cooperating to receive and transfer the insulation pipe, and a material receiving cylinder located on one side of the discharge hole and used to push the second support frame to drive the second roller to separate from the first roller for material discharge.

[0010] Furthermore, in the above technical solution, one side of the first roller and the second roller are both formed with arc-shaped annular grooves, and they are symmetrically installed on the first support frame and the second support frame, and can be connected to form a positioning groove for positioning the heat insulation pipe transfer.

[0011] Furthermore, in the above technical solution, the spray module includes a third support frame installed on one side of the frame for installing the release agent spray can, a striking cylinder located at the lower end of the third support frame for vibrating the release agent spray can, and a spray cylinder located at the upper end of the third support frame for pressing the release agent spray can.

[0013] Furthermore, in the above technical solution, the punching module includes a positioning block disposed on the horizontal moving module for positioning the insulation pipe, a cutting assembly disposed on one side of the positioning block for cutting the insulation pipe, a punching cylinder disposed on the horizontal moving module for driving the cutting assembly to approach and move away from the positioning block, a discharge block disposed beside the cutting assembly for pushing off waste material on the insulation pipe, and a chip removal cylinder disposed on the horizontal moving module for pushing the discharge block to contact the insulation pipe.

[0014] Furthermore, in the above technical solution, the frame is also provided with a pressure cap device that extends to the material receiving module and is used to limit the position of the insulation pipe.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, the frame is connected and set at the end of the fixed-length pipe cutting machine. The material receiving module receives the insulation pipe sent from the fixed-length pipe cutting machine and transfers it to one end of the horizontal moving module. The horizontal moving module moves the punching module to contact the end of the insulation pipe. The punching module punches the end of the insulation pipe to form a preset groove. Finally, the spraying module sprays release agent onto the end of the insulation pipe. The fixed-length pipe cutting machine then cuts the insulation pipe to complete the discharge.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figures 1 to 7As shown, a heat insulation pipe punching mechanism includes: a frame 1, a blanking receiving module 2 disposed at one end of the frame 1 for carrying the heat insulation pipe A, a punching module 3 disposed at the other end of the frame 1 for punching an opening, a horizontal moving module 4 disposed on the frame 1 for moving the punching module 3 closer to or away from the heat insulation pipe A, and a spraying module 5 disposed beside the blanking receiving module 2 for spraying release agent onto the heat insulation pipe A. The frame 1 is also provided with a front limit switch 6 and a rear limit switch 7 for stopping the movement of the punching module 3. The frame 1 is connected to the end of the fixed-length pipe cutter. The material receiving module 2 receives the insulation pipe A sent from the fixed-length pipe cutter and transfers it to one end of the horizontal moving module 4. The horizontal moving module 4 moves the punching module 3 to contact the end of the insulation pipe A. The punching module 3 then punches the end of the insulation pipe A to form a preset groove. Finally, the spraying module 5 sprays release agent onto the end of the insulation pipe A. The fixed-length pipe cutter then cuts the insulation pipe to complete the discharge.

[0025] The material receiving module 2 includes a first support frame 21 and a second support frame 22 suspended above the discharge hole 10 in the middle of the frame 1 and separable; a plurality of first rollers 23 and second rollers 24 arranged on the first support frame 21 and the second support frame 22 to receive and transfer the insulation pipe A; and a material receiving cylinder 25 located on one side of the discharge hole 10 to push the second support frame 22 to drive the second roller 24 to separate from the first roller 23 for material discharge. One side of each of the first rollers 23 and the second roller 24 is formed with an arc-shaped annular groove, and they are symmetrically installed on the first support frame 21 and the second support frame 22, and can be connected to form a positioning groove 20 for positioning the insulation pipe A during transfer. The first roller 23 and the second roller 24 are detachable and connected to support the insulation pipe A sent out by the fixed-length pipe cutter. The end of the insulation pipe A is transferred to one end of the horizontal moving module 4. After the punching module 3 completes the punching of the insulation pipe A, the second support frame 22 is driven by the dropping cylinder 25 to separate the second roller 24 from the first roller 23, so that the insulation pipe A falls from between the first roller 23 and the first roller 24 and falls into the finished product collection basket below through the discharge hole 10.

[0026] The spray module 5 includes a third support frame 52 mounted on one side of the frame 1 for mounting the release agent spray can 51, a striking cylinder 53 located at the lower end of the third support frame 52 for vibrating the release agent spray can 51, and a spray cylinder 54 located at the upper end of the third support frame 52 for pressing the release agent spray can 51. In this embodiment, the release agent spray can 51 is detachably mounted on the third support frame 52. In use, the release agent spray can 51 is struck by the striking cylinder 53 below to make the release agent shake, and then the spray cylinder 54 presses the nozzle of the release agent spray can 51 to spray the release agent into the cut of the insulation pipe A.

[0027] The horizontal moving module 4 includes a guide rail 41 mounted on the frame 1, a movable seat 42 slidably mounted on the guide rail 41 and capable of approaching and moving away from the material receiving module 2, a leading edge positioning member 43 mounted on the movable seat 42 and extending forward for positioning the insulation pipe A, a pulley assembly 44 mounted on one side of the frame 1 for driving the movable seat 42, and a motor 45 for driving the pulley assembly 44. The leading edge positioning member 43 is provided with a first detection device 46 for detecting the insulation pipe A.

[0028] The punching module 3 includes a positioning block 31 disposed on the horizontal moving module 4 for positioning the insulation pipe A, a cutting assembly 32 disposed on one side of the positioning block 31 for cutting the insulation pipe A, a punching cylinder 33 disposed on the horizontal moving module 4 for driving the cutting assembly 32 to approach and move away from the positioning block 31, a discharge block 34 disposed beside the cutting assembly 32 for pushing away waste material on the insulation pipe A, and a chip removal cylinder 35 disposed on the horizontal moving module 4 for pushing the discharge block 34 to contact the insulation pipe A.

[0029] The frame 1 is also provided with a capping device 9 that extends to the material receiving module 2 and is used to limit the insulation pipe A. By using the capping device 9 to limit the insulation pipe A in the positioning groove 20 between the first roller 23 and the second roller 24, the insulation pipe A cannot fall from the material receiving module 2 during transmission, cutting and trimming.

[0030] In summary, when using this utility model, the frame 1 is directly connected and installed at the end of the fixed-length pipe cutter. After the insulation pipe A is sent out from the fixed-length pipe cutter, the material receiving module 2 first lifts the insulation pipe A and transfers it to one end of the horizontal moving module 4. The horizontal moving module 4 moves the punching module 3 to connect with the end of the insulation pipe A. Then, the punching module 3 punches the end of the insulation pipe A to form a suitable cut. Subsequently, the horizontal moving module 4 drives the punching module 3 to leave the insulation pipe A. After the fixed-length pipe cutter cuts the insulation pipe A to the specified length, the material receiving module 2 releases the support of the insulation pipe A, so that the insulation pipe A is discharged from the discharge hole 10 below.

[0031] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
