DETAILED DESCRIPTION

[0027] With reference to the drawings of the utility model embodiments, the technical solutions in the utility model embodiments will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the utility model.

[0028] In the description of the utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the utility model.

[0029] Please refer to Figures 1-6 As shown in the figure, the utility model is a plastic pipe cutting device with a cooling mechanism, which comprises a shell 1, the shell 1 is provided with a cutting mechanism 2, the inside of the shell 1 is slidably installed with a sliding plate 8, the top of the sliding plate 8 is provided with a plastic pipe clamping mechanism 3, the inside of the plastic pipe clamping mechanism 3 is provided with a plastic pipe 4, the inside of the sliding plate 8 is screwedly installed with a lifting mechanism 5, the lifting mechanism 5 is screwedly installed with the shell 1, the inside of the shell 1 and located at the bottom of the sliding plate 8 is provided with a collecting box 6, one end of the collecting box 6 is communicated with a cooling mechanism 7, one end of the cooling mechanism 7 is located at one side of the cutting mechanism 2.

[0030] Firstly, the plastic pipe 4 to be cut is placed in the plastic pipe clamping mechanism 3, then the staff rotates the plastic pipe clamping mechanism 3 by hand, so that the internal components at both ends of the plastic pipe clamping mechanism 3 move towards the direction of the plastic pipe 4 until the plastic pipe 4 is stably clamped, the plastic pipe clamping mechanism 3 is arranged at the top of the sliding plate 8, the cutting mechanism 2 is started, then the staff rotates the lifting mechanism 5 by hand, through the rotation of the lifting mechanism 5, the screwedly installed sliding plate 8 can slide and rise on the shell 1, the plastic pipe clamping mechanism 3 and the plastic pipe 4 on the sliding plate 8 will also rise together until the plastic pipe 4 rises to the cutting mechanism 2, the cutting mechanism 2 cuts the plastic pipe 4 stably clamped by the plastic pipe clamping mechanism 3 according to the specific size requirement, so as to cut the longer plastic pipe 4 into the appropriate length to meet the needs of different application scenarios such as building engineering, electrical installation and the like, in the cutting process, the lifting mechanism 5 will continue to rotate to drive the sliding plate 8 and the plastic pipe 4 to rise until the plastic pipe 4 is cut off.

[0031] The cooling liquid is placed in the collecting box 6. Since the cooling mechanism 7 is connected to the collecting box 6 at one end and located at the side of the cutting mechanism 2 at the other end, when the cooling mechanism 7 is started, the cooling mechanism 7 will pressurize the cooling liquid in the collecting box 6 and deliver it to the location of the cutting mechanism 2. During the cutting of the plastic pipe, the cooling liquid flowing out of the cooling mechanism 7 is directly sprayed to the cutting mechanism 2 and the cutting position. The cooling liquid absorbs the heat generated by the friction between the cutting mechanism 2 and the plastic pipe 4 during cutting, thereby reducing the temperature of the cutting mechanism 2, preventing the cutting mechanism 2 from being damaged due to overheating, and also reducing the temperature of the cut part of the plastic pipe 4, avoiding quality problems such as deformation and melting of the cut part of the plastic pipe 4 due to high temperature.

[0032] In one embodiment, for the above-mentioned plastic pipe clamping mechanism 3, the plastic pipe clamping mechanism 3 comprises two mounting blocks 301, both of which are fixedly installed on the sliding plate 8. A sliding rod 302 is fixedly installed between the two mounting blocks 301. Two clamping claws 303 are symmetrically and slidingly installed on the two sliding rods 302. The two clamping claws 303 are provided with arc-shaped grooves at one end close to each other.

[0033] A bidirectional threaded rod 304 is rotatably installed on the two mounting blocks 301. The threads on the bidirectional threaded rod 304 are opposite, and the two clamping claws 303 are respectively located at the two threads. The bidirectional threaded rod 304 is rotatably installed with the two mounting blocks 301. A rotating handle 305 is fixedly installed at one end of the bidirectional threaded rod 304.

[0034] When it is necessary to clamp the plastic pipe 4 for cutting, the operator rotates the rotating handle 305, which drives the bidirectional threaded rod 304 to rotate. Since the threads on the bidirectional threaded rod 304 are opposite and the two clamping claws 303 are respectively located at the two threads, under the action of the threads, the two clamping claws 303 will move relatively or oppositely along the sliding rod 302, and the sliding rod 302 will guide the two clamping claws 303.

[0035] When the rotating handle 305 is rotated forward, the two clamping claws 303 move close to each other, and the arc-shaped grooves gradually approach the plastic pipe 4 until they contact and tightly clamp the plastic pipe 4. The design of the arc-shaped grooves can better fit the circular outer surface of the plastic pipe 4, provide stable and uniform clamping force, prevent the plastic pipe 4 from shifting or shaking during cutting, and ensure that the cutting knife 206 can accurately cut the plastic pipe 4.

[0036] When the cutting is completed, the rotating knob 305 is rotated reversely, the two clamping claws 303 are separated from each other, the clamping of the plastic pipe 4 is released, the cut plastic pipe 4 is taken out, and the pipe to be cut can be replaced, so that the plastic pipe 4 is conveniently and stably clamped during the cutting, and the working efficiency and cutting precision of the plastic pipe 4 cutting device are effectively improved.

[0037] In one embodiment, for the cutting mechanism 2, the cutting mechanism 2 comprises a driving motor 201 fixedly installed on the shell 1, and a first synchronous wheel 202 fixedly installed at an output end of the driving motor 201.

[0038] The other end of the synchronous belt 203 is rotatably installed with a second synchronous wheel 204, one end of the second synchronous wheel 204 is rotatably installed with a rotating shaft 205, the rotating shaft 205 is rotatably installed on the shell 1, and the cutting knife 206 is fixedly installed at one end of the rotating shaft 205.

[0039] When the cutting operation starts, the driving motor 201 is started. The output end of the driving motor 201 drives the first synchronous wheel 202 to rotate at high speed. Since the synchronous belt 203 is wound around the circumferential surfaces of the first synchronous wheel 202 and the second synchronous wheel 204, the rotating motion of the first synchronous wheel 202 is transmitted to the second synchronous wheel 204 through the synchronous belt 203, so that the second synchronous wheel 204 rotates synchronously with the first synchronous wheel 202. The rotating shaft 205 connected with the second synchronous wheel 204 starts to rotate under the support of the shell 1, and in turn drives the cutting knife 206 fixed at one end of the rotating shaft 205 to rotate at high speed.

[0040] In one embodiment, for the lifting mechanism 5, the lifting mechanism 5 comprises two threaded rods 501, both of which are rotatably installed on the shell 1, one of the two threaded rods 501 is fixedly installed with a handle 502, the two threaded rods 501 are screwedly installed with the sliding plate 8, the outer walls of the two threaded rods 501 are fixedly installed with belt pulleys 503, and the belt pulley 504 is rotatably installed between the two belt pulleys 503.

[0041] Subsequently, the handle 502 is rotated. Since one of the threaded rods 501 is fixedly connected with the handle 502, the threaded rod 501 rotates with the handle 502, and the pulley 503 on the outer wall of the threaded rod 501 rotates synchronously. Through the transmission of the belt 504, the pulley 503 on the outer wall of the other threaded rod 501 rotates, so that the other threaded rod 501 also rotates in the same direction and at the same speed. Thus, the synchronous rotation of the two threaded rods 501 is achieved. Since the two threaded rods 501 are in threaded connection with the sliding plate 8, and the sliding plate 8 is slidingly installed on the shell 1, the sliding plate 8 is vertically slidingly installed on the shell 1, and when the two threaded rods 501 rotate synchronously, the sliding plate 8 moves linearly upwards along the shell 1, thereby achieving the upward movement function. This process also drives the bidirectional threaded rod 304, the clamping jaw 303, and the plastic pipe 4 on the sliding plate 8 to move upwards. When the plastic pipe 4 moves upwards to the position below the cutting knife 206 and contacts the cutting knife 206, the cutting knife 206 rotates at high speed and exerts a shearing force on the plastic pipe 4 due to the sharp edge of the cutting knife 206. The sliding plate 8 continues to drive the plastic pipe 4 to move upwards until the plastic pipe 4 is cut off.

[0042] In one embodiment, the cooling mechanism 7 includes a cooling pump 701. One end of the cooling pump 701 is connected with a liquid inlet pipe 702, the other end of the liquid inlet pipe 702 is connected with the collection tank 6, the other end of the cooling pump 701 is connected with a liquid outlet pipe 703, the liquid outlet pipe 703 is fixedly installed on the shell 1, and the other end of the liquid outlet pipe 703 is located on one side of the cutting knife 206.

[0043] When the cooling pump 701 is started, the cooling liquid in the collection tank 6 is sucked into the cooling pump 701 through the liquid inlet pipe 702. The cooling pump 701 pressurizes the cooling liquid, and the cooling liquid flows to the position of the cutting knife 206 through the liquid outlet pipe 703. During the cutting of the plastic pipe 4, the cooling liquid flowing out of the liquid outlet pipe 703 is directly sprayed to the cutting knife 206 and the cutting position. The cooling liquid absorbs the heat generated by the friction between the cutting knife 206 and the plastic pipe 4 during the cutting process, thereby reducing the temperature of the cutting knife 206 and preventing the cutting knife 206 from being damaged due to overheating. At the same time, the temperature of the cut part of the plastic pipe 4 is also reduced, which avoids the quality problems such as deformation and melting of the cut part of the plastic pipe 4 due to high temperature.
