Description
Technical Field
[0001] The utility model belongs to the technical field of pipe processing equipment, and in particular relates to a processing and polishing device for polytetrafluoroethylene pipes. Background Art
[0002] Polytetrafluoroethylene, commonly known as the "king of plastics", is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. Its chemical formula is (C2F4)n. It has excellent heat and cold resistance and can be used for a long time at 180-260°C. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene is resistant to high temperatures and has a very low friction coefficient. Therefore, it can be used as a lubricant and has become an ideal coating for the inner layer of easy-to-clean water pipes.

Therefore, a grinding device for polytetrafluoroethylene pipe processing is proposed. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Reference Figure 1 As shown, the utility model provides a device for processing and polishing polytetrafluoroethylene pipes, including a workbench, a bracket 11 is fixedly connected to the upper end of the workbench, a first electric telescopic rod 3 is fixedly connected to the lower end of the bracket 11, and a polishing mechanism 4 is arranged at the output shaft end of the first electric telescopic rod 3. The polishing mechanism 4 is used for polishing the end face and the outer wall of the pipe. The outer wall and the end face of the pipe can be polished by the arranged polishing mechanism 4, thereby solving the problem that other polishing equipment needs to be replaced in the current process of polishing polytetrafluoroethylene pipes, making the polishing of polytetrafluoroethylene pipes too cumbersome.
[0022] In a further embodiment, referring to Figure 4 The upper end of the workbench 1 is rotatably connected to a driven roller 2 through a bearing seat. The driven roller 2 is provided with two groups and is respectively located at the front and rear sides of the first electric telescopic rod 3.
[0023] In this embodiment, by placing the pipe between two groups of driven rollers 2, the pipe can be placed stably, the placed pipe rolls, and the pipe is fixed at the same time.
[0024] In a further embodiment, referring to Figure 1-Figure 2The grinding mechanism 4 includes a lifting plate 41, a driving assembly 42 and a grinding assembly 43. The output shaft end of the first electric telescopic rod 3 is fixedly connected to the lifting plate 41. The grinding assembly 43 includes a grinding roller 431 and a grinding disc 432. The lower right end of the lifting plate 41 is rotatably connected to the grinding roller 431 through a fixed frame. The right side wall of the grinding roller 431 is fixedly connected to the grinding disc 432. The right end of the fixed frame located on the right side of the grinding roller 431 is fixedly connected to the second motor 433. The output shaft end of the second motor 433 is fixedly connected to the right end of the grinding disc 432.
[0025] In this embodiment, the first electric telescopic rod 3 is started to drive the lifting plate 41 to move downward, thereby driving the grinding roller 431 to move downward, so that the grinding roller 431 and the outer wall of the pipe are in contact with each other, and then the second motor 433 is started to drive the grinding roller 431 to rotate, so that the side wall of the pipe can be polished.
[0026] In a further embodiment, referring to Figure 2 The driving component 42 includes a first motor 422 and an active roller 421. The lower left end of the lifting plate 41 is rotatably connected to the active roller 421 through a fixed frame. The left end of the fixed frame located on the left side of the active roller 421 is fixedly connected to the first motor 422. The output shaft end of the first motor 422 is fixedly connected to the left side of the active roller 421.
[0027] In this embodiment, the first motor 422 is started to drive the active roller 421 to rotate. As the lifting plate 41 moves downward, the side wall of the active roller 421 abuts against the outer wall of the pipe, thereby driving the pipe to rotate, thereby providing power for the rotation of the pipe.
[0028] In a further embodiment, referring to Figure 2 The active roller 421 is made of rubber material, and the lower side wall of the active roller 421 and the lower side wall of the grinding roller 431 are located on the same horizontal plane.
[0029] In this embodiment, since the lower side wall of the active roller 421 and the lower side wall of the grinding roller 431 are located on the same horizontal plane, the active roller 421 and the grinding roller 431 contact the outer wall of the pipe at the same time when the lifting plate 41 moves downward. Since the outer wall of the active roller 421 is made of rubber, on the one hand, it can increase the friction between the pipe and the rubber has a certain elasticity, so that the lifting plate 41 can move downward a certain distance, so that the grinding roller 431 grinds the outer wall of the pipe deeper, and then grinds the outer wall of the pipe smoother.
[0030] In a further embodiment, referring to Figure 1-Figure 2 The lower end of the fixed frame located on the right side of the lifting plate 41 is fixedly connected with a connecting rod 44, and the lower end of the connecting rod 44 is fixedly connected with a stop block 45, and the lower end of the stop block 45 penetrates to the lower end of the workbench 1 and is slidably connected thereto.
[0031] In this embodiment, by providing a connecting rod 44 and a stop block 45, before grinding the pipe, the end face of the pipe is abutted against the left end of the stop block 45, and then the downward movement of the lifting block will drive the connecting rod 44 to move downward, so that the end face of the pipe is separated from the abutment of the stop block 45, and at the same time, the end face of the pipe will abut against the left end of the grinding disk 432, and then under the pressure of the extrusion mechanism 5, the right end face of the pipe is tightly attached to the grinding disk 432, and the grinding roller 431 is rotated to drive the grinding disk 432 to rotate, so that the end face of the pipe can be ground.
[0032] In a further embodiment, referring to Figure 3 A squeezing mechanism 5 is provided at the upper left end of the workbench 1, and the squeezing mechanism 5 includes a moving plate 52 and a pressing plate 54. A second electric telescopic rod 51 is fixedly connected to the upper left end of the workbench 1 through a fixed seat, and the output shaft end of the second electric telescopic rod 51 is rotatably connected to the moving plate 52. Through holes are provided on the left end surfaces of the upper and lower sides of the moving plate 52, and a connecting rod 53 is slidably connected inside the through hole. The right end of the connecting rod 53 is fixedly connected to the pressing plate 54, and the left end of the connecting rod 53 is fixedly connected to an anti-sliding block 55, and the right end surface of the anti-sliding block 55 abuts against the left end surface of the moving plate 52. A spring 56 is sleeved on the side wall of the connecting rod 53 located at the left end of the moving plate 52, and the left end of the spring 56 is fixedly connected to the right end of the moving plate 52, and the right end of the spring 56 is fixedly connected to the left end of the pressing plate 54.
[0033] In this embodiment, the second electric telescopic rod 51 is started to drive the movable plate 52 to move to the left. The movable plate 52 moving to the left drives the pressure plate 54 to move to the left through the spring 56, so that the right end surface of the pressure plate 54 abuts against the left end surface of the pipe. Then the second electric telescopic rod 51 is driven to make the movable plate 52 continue to move to the left, thereby compressing the spring 56, so that the pressure plate 54 has a thrust to move to the right, which facilitates the grinding disc 432 to grind the right end surface of the pipe.
[0034] The working principle of the utility model is as follows: the pipe is placed above the driven roller 2, and then the second electric telescopic rod 51 is driven to drive the moving plate 52 to move to the left. The moving plate 52 moving to the left drives the pressing plate 54 to move to the left through the spring 56, so that the right end surface of the pressing plate 54 abuts against the left end surface of the pipe. Then the second electric telescopic rod 51 is driven to make the moving plate 52 continue to move to the left, so that the spring 56 can be compressed, so that the pressing plate 54 has a thrust to move to the right, and then the first electric telescopic rod 3 is started to drive the lifting plate 41 to move downward. The lifting plate 41 moves downward and drives the active roller 421 and the grinding roller 431 to move downward at the same time, so that the active roller 421 and the grinding roller 431 abut against each other. When the lifting plate 41 moves downward, the moving plate 52 moves downward. At the same time, the connecting rod 44 is driven to move downward, and the connecting rod 44 moves downward, driving the block 45 to move downward, so that the right end face of the pipe and the left end of the block 45 fall off and abut against each other. At the same time as the abutment is separated, the pipe is pushed by the pressure plate 54, so that the right end face of the pipe and the left end of the grinding disk 432 abut against each other. Then, by starting the first motor 422, the active roller 421 rotates, thereby driving the pipe to rotate. When the first motor 422 is started, the second motor 433 is started at the same time, thereby driving the grinding roller 431 and the grinding disk 432 to rotate at the same time, so that the end face and the outer wall of the pipe can be polished at the same time, thereby solving the problem that other grinding equipment needs to be replaced in the current process of grinding polytetrafluoroethylene pipes, making the grinding of polytetrafluoroethylene pipes too cumbersome.
