[0003] Problems with existing technology:

[0004] Existing pipe cutting and grinding devices can effectively remove burrs and unevenness during use. However, the diameter of the grinding head is fixed, and the inner and outer sides of the cut need to be ground twice due to the different diameters. When changing to pipes of different diameters, different grinding heads also need to be changed, which is quite troublesome and reduces work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic pipe cutting and grinding device. The grinding component is designed to allow the diameter of the grinding head to be freely adjusted according to the needs of the pipe. The internal grinding component design allows the diameter of the grinding head on the inner side of the pipe to also be changed, so that the inner and outer sides of the cut can be ground at the same time. Depending on the grinding needs, the output distance of the hydraulic press can also be adjusted to grind and bevel the pipe cut.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A plastic pipe cutting and grinding device includes: a grinding table, a transmission belt inside the grinding table, a pipe to be processed placed on the top of the transmission belt, a hydraulic press slidably mounted on both sides of one end of the top of the grinding table, a drive motor fixedly connected to the output end of the hydraulic press, and a grinding component provided at the output end of the drive motor.

[0008] The grinding assembly includes an assembly housing. A transmission ring is fixedly connected to one end of the assembly housing away from the drive motor.

[0010] An internal grinding motor is fixedly installed inside the inner grinding shell. The output end of the internal grinding motor is fixedly connected to a helical thread head, and the end of the helical thread head is threadedly connected to a threaded plate.

[0011] An external grinding motor is fixedly installed on the inner wall of the component housing. A cross transmission frame is fixedly connected to the side of the oblique thread head two near the external grinding motor. The output end of the external grinding motor is connected to the cross transmission frame via a chain.

[0012] The surface of the transmission ring is provided with an annular array of oblique holes. Each oblique hole contains a threaded plate, which is threaded to an oblique thread head. The end of the threaded plate is fixedly connected to a corresponding external grinding head.

[0013] The inner diameter of the outer grinding head gradually decreases as it approaches the drive motor, while the outer diameter of the inner grinding head gradually increases as it approaches the drive motor. Air inlets are arrayed on the outer surface of the component housing.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1 - Figure 3 As shown, a plastic pipe cutting and grinding device includes: a grinding table 1, a transmission belt 2 is provided inside the grinding table 1, a pipe 3 to be processed is placed on the top of the transmission belt 2, a hydraulic press 4 is slidably installed on both sides of one end of the top of the grinding table 1, a drive motor 5 is fixedly connected to the output end of the hydraulic press 4, and a grinding component 6 is provided at the output end of the drive motor 5.

[0027] When it is necessary to grind the cut end of a plastic pipe, firstly, the hydraulic press 4 is used to adjust the approximate distance between the grinding component 6 and the cut plastic pipe. Then, the grinding component 6 is adjusted to meet the diameter of the pipe to be ground, and the output distance of the hydraulic press 4 is adjusted at the same time. Then, the drive motor 5 is started to drive the grinding component 6 to rotate. The cut plastic pipe is placed on the groove opened in the transmission belt 2. As the transmission belt 2 rotates, the pipe to be processed 3 passes through the middle position of the two grinding components 6 in sequence. Then, the drive motor 5 pushes the grinding component 6 to grind the plastic pipe.

[0028] See attached document Figure 3 - Figure 4The grinding assembly 6 includes an assembly housing 601. A transmission ring 602 is fixedly connected to the end of the assembly housing 601 away from the drive motor 5. An outer grinding head 603 and an inner grinding head 604 are arranged on one side of the transmission ring 602, and the outer grinding head 603 and the inner grinding head 604 are arranged in a ring array. A second helical threaded head 609 is rotatably installed inside the transmission ring 602, and an inner grinding assembly 610 is arranged inside the second helical threaded head 609. An outer grinding motor 606 is fixedly installed on the inner wall of the assembly housing 601. A cross transmission frame 607 is fixedly connected to the side of the second helical threaded head 609 near the outer grinding motor 606. The output end of the outer grinding motor 606 is connected to the cross transmission frame 607 through a chain.

[0029] According to the above structure, the outer grinding head 603 is used to grind the outer side of the pipe cut. When it is necessary to adjust the inner side of the outer grinding head 603 to meet the outer diameter of the pipe cut to be ground, the outer grinding motor 606 is started to drive the oblique thread head 609 to rotate through the chain. At this time, the oblique thread head 609 rotates in the transmission ring 602 and the threaded plate 608 connected to it moves centripetally under the drive of the thread at the end of the oblique thread head 609, thereby changing the inner diameter of the outer grinding head 603.

[0030] See attached document Figure 4 - Figure 6 The internal grinding assembly 610 includes a transmission inner ring 611, one end of which is fixedly connected to an internal grinding housing 615. The internal grinding housing 615 is fixedly connected to a second inclined threaded head 609. An inclined hole 1 is formed in an annular array on the surface of the transmission inner ring 611. A threaded plate 1 612 is slidably installed inside each inclined hole 1. The end of the threaded plate 1 612 is fixedly connected to the corresponding internal grinding head 604. An internal grinding motor 613 is fixedly installed inside the internal grinding housing 615. An inclined threaded head 1 614 is fixedly connected to the output end of the internal grinding motor 613. The end of the inclined threaded head 1 614 is threadedly connected to the threaded plate 1 612.

[0031] Based on the above structure, the internal grinding head 604 operates on the same principle as the external grinding head 603. When it is necessary to change the outer diameter of the internal grinding head 604, it is only necessary to start the internal grinding motor 613. Under the drive of the internal grinding motor 613, the oblique thread head 614 rotates inside the transmission inner ring 611. At this time, the threaded plate 612 slides inside the oblique hole 614 under the transmission of the thread at the end of the oblique thread head 614, thereby causing the internal grinding head 604 to move centrifugally or centrifugally, thus achieving the purpose of changing the diameter of the pipe that can be ground.

[0032] See attached document Figure 3 - Figure 6 The inner diameter of the outer grinding head 603 gradually decreases as it approaches the drive motor 5, while the outer diameter of the inner grinding head 604 gradually increases as it approaches the drive motor 5. An air inlet 605 is arrayed on the outer surface of the component housing 601.

[0033] According to the above structure, since the inner hole of the outer grinding head 603 and the periphery of the inner grinding head 604 form a cone shape when rotating, the deeper the tube to be processed 3 enters, the larger the grinding diameter. Thus, by increasing the output distance of the hydraulic press 4, the function of the device for beveling the tube to be processed 3 can be enhanced. The side wall of the component housing 601 corresponding to the air inlet 605 is set to be inclined. When the grinding component 6 rotates, it can guide the outside air into the component housing 601 for blowing out grinding debris.

[0034] The working principle of this utility model is as follows: When it is necessary to grind the cut of a plastic pipe, firstly, the approximate distance between the grinding component 6 and the cut plastic pipe is adjusted by the hydraulic press 4, and then the grinding component 6 is adjusted to meet the diameter of the pipe to be ground. At the same time, the output distance of the hydraulic press 4 is adjusted, and then the drive motor 5 is started to drive the grinding component 6 to rotate. The cut plastic pipe is placed on the groove opened in the transmission belt 2. As the transmission belt 2 rotates, the pipe to be processed 3 passes through the middle position of the two grinding components 6 in sequence. Then, the drive motor 5 pushes the grinding component 6 to grind the plastic pipe.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
