For example, the patent application number is CN202022533127.3, a cutting device for air-conditioning pipe production, including a top plate, a sleeve and a ferrule are fixedly connected to the top of the top plate, a notch is opened on the outside of the sleeve extending outward one centimeter, a slide groove is opened at the bottom of the top plate, a slide rail is slidably connected to the inner side of the slide groove, and a box is fixedly connected to the bottom of the slide rail. A rotating motor is installed on the inner wall of the box, and the output end of the rotating motor is rotatably connected to a rotating shaft. A blade is sleeved on the outside of the rotating shaft, and a fan is electrically connected to the bottom of the rotating motor extending one centimeter in the vertical direction. The air outlet of the fan is bonded with a gauze. This application solves the problem that the existing air-conditioning pipe cutting device has insufficient control over the cutting length of the pipe during use, resulting in deviations in the length of the pipe after cutting, affecting the subsequent use of the pipe, and the plastic waste generated by the cutting cannot be effectively collected and recycled, which increases the probability of plastic particles being inhaled into the human body and affects the health of workers.

[0003] However, the existing cutting devices usually perform direct horizontal cutting after fixing the pipeline, which causes the pipeline to be subjected to force on one side during the cutting process. Under this force, the pipeline will be deformed, which in turn affects the two ends of the pipeline after cutting and causes a certain deviation in the length of the pipeline, which not only causes material waste but also requires further processing. For this reason, the present application designs an air-conditioning pipeline fixed-distance cutting device, which can accurately cut the pipeline to avoid deviation in the pipeline length.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The first pulley is driven by the transmission belt to rotate. During the rotation of the first pulley, the first connecting rod can drive the rotating rod to rotate, so that the feeding clamping roller rotates and drives the pipe to move, thereby realizing automatic feeding operation. In order to achieve precise distance cutting, a number of distance measuring through holes are opened on the surface of the distance measuring disk during the feeding process.

Compared with the direct cutting in the prior art, this application can avoid the stress deformation of the pipe, thereby ensuring the length and shape of the pipe end.

[0019] 5. During the cutting process, the second bevel gear on the housing moves and fits around the first bevel gear by rotating the rotating ring, so that the movable sleeve and the adjusting screw thread cooperate, and then the movable sleeve will continue to move toward the pipe direction to ensure that the cutting blade can completely cut the pipe.

[0034] By cooperating with the photoelectric sensor 5022 and a plurality of distance measuring holes 2027, when the distance measuring disk 2026 rotates following the feeding clamping roller 2022, the number of distance measuring holes 2027 through which the photoelectric sensor 5022 passes is used to realize precise control of the distance of pipeline transportation. When the pipeline enters the corresponding distance, the photoelectric sensor 5022 will transmit a signal to the PLC controller, and then the PLC controller will start the switching cylinder 503 to switch the drive motor 5032 to control the cutting blade 311 to cut down, and the cutting blade 311 will be reset after the cutting is completed, and the switching cylinder 503 will be started again to switch to realize the processing of subsequent pipelines.

[0035] In the present application, a boss 3062 is fixedly mounted on the outer side of the support ring 306, a transmission gear 3063 is rotatably mounted inside the boss 3062, a drive motor 3064 is fixedly mounted on the outer side of the boss 3062, an output end of the drive motor 3064 is fixedly connected to the transmission gear 3063, a plurality of tooth grooves 3072 are provided on the outer side of the rotating ring 307, and the transmission gear 3063 meshes with the plurality of tooth grooves 3072.

[0037] By starting the driving motor 3064 to drive the transmission gear 3063 to engage with a plurality of tooth grooves 3072, the rotation of the rotating ring 307 can be achieved. During the rotation of the rotating ring 307, the cutting blade 311 will rotate around the pipe to achieve circular cutting. Compared with the direct cutting in the prior art, the present application can avoid the situation where the pipe is subjected to stress and deformation, thereby ensuring the length and shape of the pipe end.

[0038] During the cutting process, the rotation of the rotating ring 307 is used to make the second bevel gear 3082 on the shell 308 move and fit around the first bevel gear 3065, so that the movable sleeve 3083 is threadedly matched with the adjusting screw rod 3081, and then the movable sleeve 3083 will continue to move toward the pipeline direction to ensure that the cutting blade 311 can completely cut the pipeline.

The above structure can reset the auxiliary roller 3095 when the cutting blade 311 is away from the pipe.

[0041] The working principle of this air conditioning pipe fixed distance cutting device: When in use, first start the control motor 406 on one side to clamp the feeding clamping roller 2022 to clamp the pipe, then start the driving motor 5032 to make the first pulley 2024 rotate under the transmission of the transmission belt 505. During the rotation of the first pulley 2024, the first connecting rod 2023 can drive the rotating rod 2021 to rotate, so that the feeding clamping roller 2022 rotates and drives the pipe to move, thereby realizing the automatic feeding operation; During the feeding process, the photoelectric sensor 5022 cooperates with a plurality of distance measuring holes 2027. When the distance measuring disk 2026 rotates following the feeding clamping roller 2022, the number of distance measuring holes 2027 through which the photoelectric sensor 5022 passes is used to accurately control the distance of the pipeline transportation. When the pipeline enters the corresponding distance, the photoelectric sensor 5022 transmits a signal to the PLC controller, and then the PLC controller starts the switching cylinder 503 to switch the driving motor 5032 to control the cutting blade 311 to cut down. After cutting, the control motor 406 on the other side is started so that the clamping plate 408 fixes one end of the pipe to facilitate subsequent cutting; During cutting, the driving motor 3064 is started to drive the transmission gear 3063 to mesh with the plurality of tooth grooves 3072, so that the rotation of the rotating ring 307 can be realized. During the rotation of the rotating ring 307, the cutting blade 311 will rotate around the pipe to realize annular cutting. During the annular cutting process, the second bevel gear 3082 on the housing 308 moves and fits around the first bevel gear 3065 by the rotation of the rotating ring 307, so that the movable sleeve 3083 and the adjusting screw rod 3081 are threadedly matched, and then the movable sleeve 3083 will continue to move toward the pipe direction to ensure that the cutting blade 311 can completely cut the pipe; After the cutting is completed, the support ring 306 is tilted by using the movable reset of the movable slide bar 304 and the matching slide bar 303, and the first bevel gear 3065 and the second bevel gear 3082 are disengaged with each other in cooperation with the flip bracket 3073, and after the disengagement, the reset spring 3084 pushes the movable sleeve 3083 to reset the height of the cutting blade 311, thereby achieving rapid reset; then the clamping plate 408 cancels the clamping so that the pipe falls after the cutting is completed.
