Technical Field

[0001] The utility model relates to the technical field of aluminum alloy lined plastic pipe peeling, in particular to an aluminum alloy lined plastic pipe peeling machine. Background Art

[0002] Aluminum alloy lined plastic composite pipe is a new type of practical pipe developed on the basis of traditional plastic pipe. It combines the physical and chemical advantages of metal and plastic materials. It has the advantages of light weight, 100% oxygen barrier, anti-ultraviolet radiation, clean and hygienic, easy installation, strong sealing and maintenance-free in water supply pipe applications. It solves the defects of plastic pipes such as bending due to thermal expansion and contraction, fear of impact, and easy aging in indoor open installation. During the construction and connection of aluminum alloy lined plastic pipes, in order to ensure the stability of the connection, it is necessary to cut off the aluminum alloy outer skin at the connecting end of the aluminum alloy lined plastic pipe. Therefore, an aluminum alloy lined plastic pipe peeling machine is used to cut the aluminum alloy outer skin.

[0003] Prior art includes a utility model with publication number CN213052792U, which discloses an aluminum alloy plastic-lined pipe peeling machine. The patent adopts a ring cutting frame: a three-jaw chuck is provided on the ring cutting frame, a ring groove is provided on the ring cutting frame and located on the outer side of the three-jaw chuck, and a slide seat moving along its inner wall is provided on the inner wall of the ring groove, a telescopic component is provided on the slide seat, and a threaded pipe telescopic along its length direction is provided on the telescopic component, a cutting rod is penetrated by the inner wall thread of the threaded pipe, and a cutting knife is provided at the end of the cutting rod; the utility model equipment solves the problem that the existing aluminum alloy plastic-lined pipe peeling machine can usually only perform a single ring cutting or linear cutting operation on the aluminum alloy outer skin when cutting and peeling the aluminum alloy outer skin, so that the aluminum alloy outer skin after cutting cannot be removed quickly and conveniently, thereby reducing the peeling efficiency of the aluminum alloy plastic-lined pipe.

[0004] In daily work, when cutting the aluminum alloy outer skin at the connecting end of the aluminum alloy lined plastic pipe, there is a problem that the equipment needs to cut the pipe surface when connecting the pipe. However, the equipment is generally fixed in shape and it is difficult to cut pipes of different sizes, which makes it difficult for the equipment to cut pipes of different shapes.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an aluminum alloy lined plastic pipe peeling machine, comprising a base, a limiting ring, a cutting knife and a pressing device, a limiting ring is arranged on the upper surface of the base, a cutting knife is arranged at one end of the limiting ring, the pressing device is arranged on the surface of the limiting ring, the pressing device comprises a moving block and a connecting column, the connecting column is fixedly connected to the surface of the limiting ring, the moving block is arranged inside the limiting ring, a threaded rod is fixedly connected to the upper surface of the moving block, the threaded rod is slidably connected to the inner wall of the connecting column, a roller is rotatably connected to the inside of the moving block, the limiting rod is fixedly connected to the upper surface of the moving block, the limiting rod is slidably connected to the inside of the limiting ring, a rotating block is rotatably connected to one end of the connecting column, the rotating block is threadedly connected to the surface of the threaded rod, an adjusting groove is provided on the surface of the rotating block, and a connecting plate is fixedly connected to the side of the connecting column.

[0007] Furthermore, a limiting column is fixedly connected to the surface of the connecting plate, and an adjusting rod is slidably connected to the surface of the limiting column. The adjusting rod is clamped with the inner wall of the adjusting groove. By setting the adjusting rod, the rotating block can be limited, thereby reducing the situation where the rotating block is easily rotated at will when the equipment is in use, causing the movement of the screw rod to move the moving block.

[0008] Furthermore, one end of the adjusting rod is fixedly connected with a sliding rod, and the sliding rod is slidably connected to the inner wall of the connecting plate. The sliding rod is provided to facilitate the limited movement of the adjusting rod.

[0009] Furthermore, a first spring is sleeved and connected to the surface of the sliding rod, and two ends of the first spring are respectively fixedly connected to the surface of the connecting plate and the surface of the adjusting rod. The first spring is provided to facilitate applying a reset elastic force to the adjusting rod.

[0010] Furthermore, an adjustment device is provided on the side of the limiting ring, and the adjustment device includes a connecting block and a positioning groove. The positioning groove is opened on the side of the cutting knife, and the connecting block is fixedly connected to the side of the limiting ring. A pull groove is opened on the side of the connecting block, and the inner wall of the pull groove is slidably connected with a pull rod, and the surface of the pull rod is fixedly connected with a positioning rod. By setting the positioning rod, the cutting knife can be limited, thereby reducing the situation where the cutting knife is prone to shaking when the equipment is in use, making it difficult for the cutting knife to cut the material.

[0011] Furthermore, the positioning rod is engaged with the inside of the positioning groove, and a pull handle is fixedly connected to the surface of the pull rod, and the pull handle is provided to facilitate the movement of the pull rod.

[0012] Furthermore, one end of the pull rod is fixedly connected to a second spring, and one end of the second spring away from the pull rod is fixedly connected to the inner wall of the pull groove. The second spring is provided to facilitate applying a restoring elastic force to the pull rod.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the device is used, the user places the pipe to be peeled and the inside of the limit ring, and then pulls the pipe cutting knife to remove the rubber on the surface of the pipe. When the device is in use, the user presses the adjusting rod, and then the adjusting rod moves to drive the first spring to displace and deform to generate elastic force, and then the adjusting rod moves out of the adjusting groove, and then the rotating block loses its restraint, and the rotating block is rotated to drive the threaded rod to move, and then the threaded rod moves to drive the moving block to move, and when the moving block moves, it drives the limit rod to move, and then the moving block moves to drive the roller to move to press and contact the surface of the pipe. By setting the pressing device, the pipe is effectively pressed, which plays a role in limiting the pressing of the pipe, reducing the need to cut the pipe surface when the device is in use. However, the device is generally fixed in shape, and it is difficult to cut pipes of different sizes, which makes it difficult for the device to cut pipes of different shapes, thereby improving the practicability of the device.

[0015] 2. In the utility model, by providing an adjustment device, when the device is in use, the user pulls the handle, and the handle moves to drive the pull rod to move. When the pull rod moves, it drives the second spring to displace and deform to generate elastic force. When the pull rod moves, it drives the positioning rod, and the positioning rod is separated from the inside of the positioning groove, and the cutting knife is freed from its restraint. By providing the adjustment device, the cutting knife is effectively adjusted, which plays a role in adjusting the cutting knife. When the device is in use, the cutting knife is generally adjusted with bolts. Long-term use of the bolts is prone to thread slippage, which can easily cause the cutting knife to shake, making it difficult to perform effective cutting, thereby improving the practicability of the device.

[0035] When the device is in use, the user pulls the handle 57, and the handle 57 moves to drive the pull rod 55 to move. When the pull rod 55 moves, it drives the second spring 56 to displace and deform to generate elastic force.

By setting the adjustment device 5, the cutting knife 3 is effectively adjusted, which plays a role in adjusting the cutting knife 3. When the device is in use, the cutting knife 3 is generally adjusted by bolts. The bolts are prone to slippage due to long-term use, which can easily cause the cutting knife 3 to shake, making it difficult to perform effective cutting, thereby improving the practicability of the device.
