Description

Technical Field

[0001] This utility model relates to the field of polymer water pipe cutting technology, and in particular to a polymer water pipe fixed-length cutting device. Background Technology

[0002] Polymer water pipes are pipes made from high-molecular polymers. They have the characteristics of wear resistance, corrosion resistance, impact resistance, self-lubrication, good flexibility, convenient installation, and long service life. They are widely used in urban water supply, gas transmission, industrial material transmission, agricultural irrigation, drainage and sewage discharge and other fields. When cutting polymer water pipes to a fixed length, the precise cutting length needs to be set in advance. Then, the water pipe is transported by the feeding mechanism, the positioning mechanism positions the water pipe, and the cutting mechanism completes the fixed-length cutting operation of the water pipe.

[0003] However, the feeding and positioning mechanisms of existing water pipe cutting equipment are specific and can only meet the needs of conveying and positioning specific water pipes. Therefore, they lack the ability to convey and position water pipes of different diameters. When the diameter of the water pipe changes, the water pipe cutting equipment cannot convey and position the water pipe. Utility Model Content

[0005] The technical solution of this utility model is: a polymer water pipe fixed length cutting device, including a cutting table, a cutting mechanism is provided on the top of the cutting table, a conveying mechanism is provided on the left side of the top of the cutting table, and a sliding table is provided on the right side of the top of the cutting table; The conveying mechanism includes a box body, a motor fixedly connected to the top of the box body, the output shaft of the motor passing through the box body and drivingly connected to a first synchronous pulley, a second synchronous pulley movably connected to the bottom of the inner cavity of the box body via a bearing, the second synchronous pulley and the first synchronous pulley being driven by a synchronous belt, a drive rubber wheel fixedly connected to the top of the box body, the bottom of the drive rubber wheel passing through the inner cavity of the box body and fixedly connected to the second synchronous pulley, a threaded seat fixedly connected to the bottom of the box body, and a threaded rod threadedly connected to the inner cavity of the threaded seat.

[0006] Preferably, after determining the diameter of the water pipe to be cut, the threaded rod is rotated. Since the threads at both ends of the threaded rod are set in opposite directions, the two boxes can achieve two motion states of contact and separation, thus quickly adapting to water pipes of different diameters. At the same time, the distance between the two slides is also adjusted to quickly adapt to the water pipe diameter. After determining the length to be cut, the distance between the scale slider and the slide is adjusted, and the cutting length is positioned in conjunction with the scale lines on the slide. By rotating the handle, the positioning plate is made to fit tightly against the inner cavity of the slide, limiting and fixing the position of the positioning baffle. After the cutting length is positioned, the water pipe is placed between the two drive rubber wheels. The output shaft of the motor drives the first synchronous wheel to rotate. The first synchronous wheel drives the second synchronous wheel and the drive rubber wheel to rotate together through the synchronous belt. Thus, the rotating drive rubber wheel transports the water pipe forward. When the right end of the water pipe is in close contact with the two positioning baffles, the motor is stopped, and the cutting mechanism begins to cut the water pipe.

[0007] Preferably, the slide is disposed on both sides of the top of the cutting table, and a first cylinder is fixedly connected to both sides of the cutting table. The output end of the first cylinder is fixedly connected to the slide, and scale lines are provided on the slide.

[0009] Preferably, the cutting mechanism includes a column fixedly connected to the top of the cutting table, a lifting frame movably connected to the column via a movable shaft, a third cylinder disposed between the column and the lifting frame, and a cutting motor fixedly connected to the bottom of the lifting frame. The output shaft of the cutting motor is bolted to a cutting saw blade. Both ends of the third cylinder are fixedly connected to U-shaped seats, and the two U-shaped seats are movably connected to the column and the lifting frame via pivot pins.

[0010] Preferably, a second cylinder is fixedly connected to both sides of the top of the cutting table, and a fixing plate is fixedly connected to the output end of the second cylinder.

[0011] Preferably, a cutting groove is provided on the top of the cutting table and on the left side of the slide table.

[0012] Preferably, a limiting slide is provided at the top of the cutting table and below the box body, the threaded seat is slidably connected to the inner cavity of the limiting slide, both ends of the threaded rod are fixedly connected to the bottom of the cutting table through bearing seats, one end of the threaded rod is fixedly connected to a turntable, and the threads at both ends of the threaded rod surface are arranged in opposite directions.

[0013] Preferably, a limiting groove is provided on the top of the cutting table, and a limiting slider is slidably connected to the inner cavity of the limiting groove. The top of the limiting slider is fixedly connected to the cutting table.

[0014] The beneficial effects of this utility model are as follows: by setting up a conveying mechanism for conveying pipes, and by adjusting the distance between the two boxes by rotating the threaded rod, it can quickly adapt to water pipes of different diameters and ensure normal conveying operations. By setting up a slide table and a first cylinder, it can quickly adjust the distance to adapt to pipes of different diameters. The distance positioning mechanism can set the cutting length and limit the pipe. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment: a polymer water pipe fixed length cutting device, including a cutting table 1, a cutting mechanism 2 is provided on the top of the cutting table 1, a conveying mechanism 3 is provided on the left side of the top of the cutting table 1, and a sliding table 4 is provided on the right side of the top of the cutting table 1. The conveying mechanism 3 includes a box body 301. A motor 302 is fixedly connected to the top of the box body 301. The output shaft of the motor 302 passes through the box body 301 and is connected to a first synchronous pulley 303. A second synchronous pulley 304 is movably connected to the bottom of the inner cavity of the box body 301 through a bearing. The second synchronous pulley 304 and the first synchronous pulley 303 are connected by a synchronous belt. A drive rubber wheel 305 is fixedly connected to the top of the box body 301. The bottom of the drive rubber wheel 305 passes through the inner cavity of the box body 301 and is fixedly connected to the second synchronous pulley 304. A threaded seat 306 is fixedly connected to the bottom of the box body 301. A threaded rod 307 is threadedly connected to the inner cavity of the threaded seat 306.

[0019] The slide table 4 is located on both sides of the top of the cutting table 1. The first cylinder 5 is fixedly connected to both sides of the cutting table 1. The output end of the first cylinder 5 is fixedly connected to the slide table 4. The slide table 4 is provided with scale lines.

[0020] The slide table 4 is provided with a distance positioning mechanism 6. The distance positioning mechanism 6 includes a scale slider 601 slidably connected to the slide table 4, a positioning baffle 602 fixedly connected to one side of the scale slider 601, a lifting screw 604 threadedly connected to the surface of the scale slider 601, a throttle 603 fixedly connected to the top of the lifting screw 604, and a positioning piece 605 movably connected to the bottom of the lifting screw 604 through a bearing.

[0021] During operation, after determining the diameter of the water pipe to be cut, the threaded rod 307 is rotated. Because the threads at both ends of the threaded rod 307 are reversed, the two housings 301 will achieve two states of contact and separation, thus quickly adapting to water pipes of different diameters. At the same time, the two first cylinders 5 will also drive the slide table 4 to adjust the distance, quickly adapting to the water pipe diameter. After determining the length to be cut, the distance of the scale slider 601 on the slide table 4 is adjusted, and the cutting length is positioned in accordance with the scale lines on the slide table 4. By rotating the handle 603, the positioning plate 605 is pressed tightly against the inner cavity of the slide table 4, and the position of the positioning baffle 602 is adjusted. After the limit is fixed and the cutting length is positioned, the water pipe is placed between two drive rubber wheels 305. The drive rubber wheels 305 directly contact the surface of the water pipe, and lossless conveying is achieved through friction. The output shaft of the motor 302 drives the first synchronous wheel 303 to rotate. The first synchronous wheel 303 drives the second synchronous wheel 304 and the drive rubber wheel 305 to rotate together through the transmission of the synchronous belt. Thus, the rotating drive rubber wheel 305 conveys the water pipe forward. When the right end of the water pipe is in close contact with the two positioning baffles 602, the motor 302 is stopped. The output shaft of the second cylinder 7 drives the fixing plate 8 to fix the water pipe, and the cutting mechanism 2 begins to cut the water pipe.

[0022] Example 2: Please refer to Figure 1 and Figure 3 The difference from Embodiment 1 is that the cutting mechanism 2 includes a column 201 fixedly connected to the top of the cutting table 1, a lifting frame 203 movably connected to the column 201 via a movable shaft, a third cylinder 202 disposed between the column 201 and the lifting frame 203, and a cutting motor 205 fixedly connected to the bottom of the lifting frame 203. The output shaft of the cutting motor 205 is bolted to a cutting saw blade 206. Both ends of the third cylinder 202 are fixedly connected to U-shaped seats 204. The two U-shaped seats 204 are movably connected to the column 201 and the lifting frame 203 via pivot pins.

[0023] The top of the cutting table 1 is fixedly connected to both sides of the second cylinder 7, and the output end of the second cylinder 7 is fixedly connected to the fixing plate 8.

[0024] A cutting groove 9 is provided on the top of the cutting table 1 and on the left side of the slide table 4.

[0025] The column 201 is used to stably support the third cylinder 202 and the cutting motor 205. During cutting, the output end of the third cylinder 202 extends, driving the lifting frame 203 and the cutting motor 205 to move closer to the water pipe. The output shaft of the cutting motor 205 drives the cutting saw blade 206 to cut the water pipe. The output end of the second cylinder 7 drives the fixing plate 8 to extend, which can fix the pipe and prevent the pipe from shifting during cutting. After cutting, the second cylinder 7 drives the fixing plate 8 to reset, and the conveying mechanism 3 continues to convey the pipe forward. When the pipe is in close contact with the positioning baffle 602, the motor 302 stops, and the second cylinder 7 and the fixing plate 8 fix the water pipe again. The cutting mechanism 2 performs the cutting operation. This cycle is repeated to achieve fixed-length cutting of the water pipe.

[0026] Example 3: Please refer to Figures 1-2 and Figure 6 The difference from Embodiment 2 is that a limiting slide 10 is provided on the top of the cutting table 1 and below the box 301. The threaded seat 306 is slidably connected to the inner cavity of the limiting slide 10. Both ends of the threaded rod 307 are fixedly connected to the bottom of the cutting table 1 through bearing seats. One end of the threaded rod 307 is fixedly connected to a turntable. The threads at both ends of the surface of the threaded rod 307 are reversed.

[0027] A limiting groove 11 is provided on the top of the cutting table 1. A limiting slider 12 is slidably connected to the inner cavity of the limiting groove 11. The top of the limiting slider 12 is fixedly connected to the slide table 4.

[0028] The setting of the limiting slide 10 can limit the movement trajectory of the threaded seat 306, ensuring that the two threaded seats 306 will not deviate in position when moving. By setting the limiting slide groove 11 and the limiting slider 12, the movement trajectory of the slide table 4 can be limited. When the slide table 4 moves, the limiting slider 12 slides in the inner cavity of the limiting slide groove 11, ensuring that the position movement of the slide table 4 will not deviate.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
