Description

Technical Field

[0001] This utility model relates to the field of water supply pipe processing technology, and in particular to a water supply pipe end grinding device. Background Technology

[0002] In the process of water resource transportation, it is usually necessary to transport it through water supply pipes. Because polyethylene (PE) material has excellent resistance to most domestic and industrial chemicals, it is widely used in the field of water supply pipes. In the production process of water supply pipes, the pipes need to be polished by polishing and grinding equipment.

[0003] A search revealed a Chinese patent publication number CN212635203U, which discloses a PE environmentally friendly water supply pipe end grinding device. The device includes a grinding frame, an electric motor mounted on the rear side wall of the grinding frame, and a grinding cylinder located inside the grinding frame via a rotating shaft at the output end of the electric motor. The inner wall of the grinding cylinder is provided with a grinding column. This patent, by setting up a grinding cylinder and a grinding column, can grind both the inner and outer walls of the pipe end simultaneously. Moreover, during the grinding process, the waste can be collected and processed through the combined action of the inclined grinding frame bottom plate and the waste outlet.

[0004] However, during the polishing process, the fine dust generated adheres to the inner and outer walls of the pipe opening. This dust may be scattered in the environment during subsequent transportation, polluting the environment. Moreover, this dust will also affect the connection quality when the pipe is connected.

[0027] Example 1

[0028] A device for grinding water pipe openings, such as Figures 1 to 3As shown, the device includes a grinding frame 1 supported on the ground by a support frame. The inner cavity of the grinding frame 1 houses a cleaning cylinder 2 and a grinding cylinder 3. The cleaning cylinder 2 is located on one side of the grinding cylinder 3. A motor 14 is mounted on the side wall of the grinding frame 1, and the output shaft of the motor 14 is detachably and fixedly connected to the grinding cylinder 3. A connecting rod 9 is slidably fitted onto the rear side wall of the grinding frame 1. One end of the connecting rod 9 is fixedly connected to the cleaning cylinder 2, and the other end is connected to a linkage plate. A telescopic rod 10 is mounted on the side wall of the grinding frame 1, located on one side of the connecting rod 9, for telescopic movement. The telescopic end of rod 10 is fixedly connected to the linkage plate. The cleaning cylinder 2 includes a coaxial outer cylinder and a central column. A discharge hole is opened on one side of the bottom end of the outer cylinder. A flow cavity that communicates with each other is opened inside the outer cylinder and the central column. A fan 11 is installed on the side wall of the grinding frame 1. A connecting hose 12 is connected to the air outlet end of the fan 11. The other end of the connecting hose 12 communicates with the flow cavity. Air jet slits 13 are opened on the inner wall of the outer cylinder and the outer wall of the central column. The two air jet slits 13 are inclined towards the connecting rod 9 at opposite ends.

[0029] The bottom inner wall of the grinding frame 1 is set as an inclined surface with one end sloping towards the ground. A base plate 4 is provided on one side of the grinding frame 1. Multiple guide rods 5 are fixedly connected to the top outer wall of the base plate 4. The outer walls of the multiple guide rods 5 are slidably fitted with the same bearing plate 6. A lifting rod is installed on the top outer wall of the base plate 4. One end of the lifting rod is connected to the bearing plate 6. The lifting rod is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. Two parallel transmission belts 7 are installed on the top outer wall of the bearing plate 6 through a support frame. Multiple V-shaped support brackets 8 are fixedly connected to the outer wall of the transmission belts 7.

[0030] In use, the water supply pipe is placed on the V-shaped support frame 8 for support. The transmission belt 7 moves the pipe to one side of the grinding cylinder 3. The user pushes the water supply pipe into the grinding cylinder 3, and the motor 14 drives the grinding cylinder 3 to rotate to grind the pipe opening. After grinding, the water supply pipe is removed from the shaft of the grinding cylinder 3, and the transmission belt 7 drives the pipe to continue moving, so that the pipe moves to one side of the cleaning cylinder 2. The telescopic rod 10 drives the connecting rod 9 to move synchronously through the linkage plate, so that the outer cylinder in the cleaning cylinder 2 is fitted over the outside of the water supply pipe, and the central column is inserted into the water supply pipe. After the cleaning cylinder 2 is completely fitted over the water supply pipe, the blower 11 is started, and high-speed airflow is introduced into the flow chamber through the connecting hose 12. Then, the dust on the outer wall and inside of the water supply pipe is blown out to one side through the jet slit 13. At the same time, the telescopic rod 10 drives the connecting rod 9 to move away from the water supply pipe until the cleaning cylinder 2 is separated from the water supply pipe. The jet slit 13 moves at a constant speed relative to the water supply pipe, blowing the dust on the outer wall and inside of the water supply pipe out of the water supply pipe. When the specifications of the water supply pipe being polished change, the polishing cylinder 3 is replaced according to the specifications of the water supply pipe. Then, the lifting rod drives the transmission belt 7 to move, and the height of the V-shaped support 8 is changed according to the specifications of the water supply pipe so that the axis of the water supply pipe supported on the V-shaped support 8 can be aligned with the axis of the polishing cylinder 3, and the water supply pipe can be inserted into the polishing cylinder 3.

[0031] The system includes a cleaning cylinder 2, a connecting rod 9, a telescopic rod 10, a fan 11, and a connecting hose 12. After grinding, the outer wall and interior of the water supply pipe can be cleaned to prevent dust generated during grinding from remaining in the water supply pipe.

[0032] By setting a base plate 4, a guide rod 5 and a bearing plate 6, and cooperating with a lifting rod, the height of the V-shaped support frame 8 can be adjusted so that the axis of the water supply pipe supported on the V-shaped support frame 8 can be aligned with the axis of the grinding cylinder 3, and the water supply pipe can be inserted into the grinding cylinder 3.

[0033] Example 2

[0034] A water supply pipe inlet grinding device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 As shown, the output shaft of the motor 14 is connected to a connecting plate 15, and a limiting plug 18 is fixedly connected to the side wall of the grinding cylinder 3. A rectangular connecting groove is opened on the side wall of the connecting plate 15, and the limiting plug 18 is inserted into the rectangular connecting groove. A pull rod 16 is slidably fitted on the side wall of the connecting plate 15. The pull rod 16 is T-shaped, and one end of the pull rod 16 is inserted into the limiting plug 18. A spring 17 is sleeved on the outer wall of the pull rod 16, and the two ends of the spring 17 are respectively connected to the pull rod 16 and the connecting plate 15.

[0035] When replacing the grinding cylinder 3, pull the lever 16 upwards. The spring 17 stretches and deforms, and the bottom end of the spring 17 disengages from the limiting block 18. At this time, the limiting block 18 can be moved out of the rectangular connecting groove. Insert the limiting block 18 on one side of the other grinding cylinder 3 into the rectangular connecting groove, release the lever 16, and the spring 17 drives the lever 16 to be inserted and fixed with the limiting block 18.

[0036] The grinding cylinder 3 is secured by a connecting plate 15, a pull rod 16, a spring 17, and a limiting block 18. Pulling the pull rod 16 releases the fixing of the grinding cylinder 3, making it easy to replace the grinding cylinder 3.

[0037] Working Principle: During use, the water supply pipe is placed on top of the V-shaped support frame 8 for support. The transmission belt 7 moves the pipe to one side of the grinding cylinder 3. The user pushes the water supply pipe into the grinding cylinder 3, and the motor 14 drives the grinding cylinder 3 to rotate, grinding the pipe opening. After grinding, the water supply pipe is removed from the shaft of the grinding cylinder 3. The transmission belt 7 continues to move the pipe, moving it to one side of the cleaning cylinder 2. The telescopic rod 10 moves synchronously with the connecting rod 9 via the linkage plate, so that the outer cylinder of the cleaning cylinder 2 fits over the outside of the water supply pipe, and the central column is inserted into the water supply pipe. After the cleaning cylinder 2 is completely fitted over the water supply pipe, the blower 11 starts, inputting high-speed airflow into the flow chamber through the connecting hose 12, and then spraying it out through the jet slit 13, blowing the dust from the outer wall and inside of the water supply pipe to one side. Simultaneously, the telescopic rod 10 drives the connecting rod 9 away from the water supply pipe. The water pipe moves in the direction of the cleaning cylinder 2 until it is separated from the water supply pipe. The air jet slit 13 moves at a constant speed relative to the water supply pipe, blowing the dust from the outer wall and inside of the water supply pipe out of the water supply pipe. When the specifications of the water supply pipe being polished change, the pull rod 16 is pulled upward, the spring 17 is stretched and deformed, and the bottom end of the spring 17 is separated from the limiting plug 18. At this time, the limiting plug 18 can be moved out of the rectangular connecting groove. The limiting plug 18 on one side of the other polishing cylinder 3 is inserted into the rectangular connecting groove. The pull rod 16 is released, and the spring 17 drives the pull rod 16 to be inserted and fixed with the limiting plug 18. The polishing cylinder 3 is replaced. Then the lifting rod drives the transmission belt 7 to move. The height of the V-shaped support 8 is changed according to the specifications of the water supply pipe so that the axis of the water supply pipe supported on the V-shaped support 8 can be aligned with the axis of the polishing cylinder 3, and the water supply pipe can be inserted into the polishing cylinder 3.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
