Description

Technical Field

[0001] This utility model belongs to the field of PE pipe cutting technology, specifically a PE pipe cutting device. Background Technology

[0002] PE pipes are widely used in urban gas transmission and distribution pipeline systems due to their advantages such as light weight, low cost, and corrosion resistance. Nowadays, the use of PE pipes is becoming more and more widespread. In the production and use process, it is usually necessary to use cutting equipment to cut PE pipes, thus requiring a PE pipe cutting device.

[0003] A Chinese patent with authorization announcement number CN211993088U discloses a PE pipe cutting device, including two opposing supports, a movable balance plate sleeved on the supports, a drive device on top of the balance plate, an arc plate connected to the output end of the drive device and located at the bottom of the balance plate, and a cutter located at the bottom of the supports corresponding to the arc plate for cutting the pipe. The arc plate has a groove to avoid the cutting position of the cutter, and the contact surface between the arc plate and the pipe has an anti-slip layer. This utility model realizes a movable and convenient pipe cutting device with precise cutting.

[0004] However, the above solution still has some problems. The device can only fix a specific PE pipe diameter, and multiple sets of clamps need to be carried on the construction site, which reduces the applicability of the device. Therefore, a PE pipe cutting device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a PE pipe cutting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a PE pipe cutting device, including: a cutting table, a base plate symmetrically installed on the upper surface of the cutting table, an air bladder installed on the inner wall of the base plate, an anti-slip pad fixedly connected to one side of the air bladder, an air pump installed on the upper surface of the cutting table, the output end of the air pump connected to the air bladder, a sealing plug provided on one side of the air bladder, two sets of clamping plates hinged to both sides of the base plate, the inner wall of the clamping plates connected to the air bladder, one side of the anti-slip pad connected to the clamping plate, bolts threadedly connected to the two sets of clamping plates, a connecting hole opened on one set of clamping plates, a plug fixedly connected to one side of the connecting hole of the other set of clamping plates, the plug slidingly connected inside the connecting hole, a rubber pad fixedly connected to one end of the plug, the rubber pad movably connected inside the connecting hole, when the rubber pad passes through the connecting hole, it cooperates with the plug to connect and fix the two sets of clamping plates.

[0007] Preferably, a baffle is hinged at the opening of the cutting table, and an elastic sheet is fixedly connected to the lower surface of the baffle. One end of the elastic sheet is fixedly connected to the lower surface of the cutting table, and a waste bin is fixedly connected to the lower surface of the cutting table. The pressure on the elastic sheet is reduced, thereby pushing the baffle back to its original position, so that the top of the waste bin is in a closed state, preventing the debris in the waste bin from flowing out, thereby improving the cleaning intensity of the debris generated during cutting.

[0008] Preferably, a filter screen is installed inside the waste bin, a fan is installed on one side of the waste bin, and an exhaust vent is opened on one side of the waste bin. The filter screen can separate the debris from the air, so that the debris stays inside the waste bin, and the air is discharged outward from the exhaust vent, thereby completing the cleaning of the debris.

[0009] Preferably, a support frame is fixedly connected to the upper surface of the cutting table, and a pneumatic cylinder is installed on the support frame. A cutting blade is installed on the telescopic end of the pneumatic cylinder. The pneumatic cylinder is started by an external controller, and the cutting blade is pushed downward to cut the PE pipe.

[0010] Preferably, the cutting blade is located above the baffle, and a spring is installed on the upper surface of the cutting blade. One end of the spring is installed on the support frame, and the spring connects to both sides of the cutting blade, thereby cooperating with the pneumatic cylinder to improve the stability of the cutting blade.

[0011] Preferably, the device is equipped with an external controller, which is used to control the start and stop of the air pump, blower and pneumatic cylinder. By controlling the air pump, blower and pneumatic cylinder through the external controller, the ease of use of the device is improved.

[0012] The advantages of this invention are as follows: two sets of clamping plates cooperate with the base plate and are fixed with bolts, inserts, and rubber pads to form a wrap around the outside of the PE pipe. An air pump is started by an external controller to inflate the airbag, so that the anti-slip pad can completely adhere to the surface of the PE pipe. The inflation degree of the airbag can be adjusted according to the size of the PE pipe, so that PE pipes of different sizes can be fixed. Therefore, during construction, only the inflation degree of the airbag needs to be adjusted to fix PE pipes of different sizes, thereby improving the applicability of the device for PE pipe cutting.

[0013] When cutting PE pipes, this invention pushes the baffle towards the waste bin when the cutting blade reaches its lowest position. This causes the debris generated during PE pipe cutting to be drawn into the waste bin by the cutting blade. In conjunction with a fan, the debris is sucked into the waste bin. As the cutting blade moves upward, the pressure on the elastic sheet decreases, pushing the baffle back to its original position. This closes the top of the waste bin, preventing debris from flowing out and thus improving the cleaning efficiency of the debris generated during cutting, preventing it from affecting the subsequent cutting quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a PE pipe cutting device includes: a cutting table 1, a base plate 2 symmetrically mounted on the upper surface of the cutting table 1, an air bladder 3 mounted on the inner wall of the base plate 2, an anti-slip pad 4 fixedly connected to one side of the air bladder 3, an air pump 5 mounted on the upper surface of the cutting table 1, the output end of the air pump 5 connected to the air bladder 3, a sealing plug provided on one side of the air bladder 3, two sets of clamping plates 6 hinged to both sides of the base plate 2, the inner wall of the clamping plates 6 connected to the air bladder 3, one side of the anti-slip pad 4 connected to the clamping plates 6, bolts 7 threadedly connected to the two sets of clamping plates 6, a connection hole 8 opened on one set of clamping plates 6, a plug rod 9 fixedly connected to one side of the connection hole 8, the plug rod 9 slidably connected inside the connection hole 8, a rubber pad 10 fixedly connected to one end of the plug rod 9, and the rubber pad 10 movably connected inside the connection hole 8;

[0023] During the production and use of PE pipes, cutting equipment is usually required to cut the pipes to meet subsequent needs. However, existing devices can only be used for specific PE pipe diameters, requiring multiple sets of clamps to be carried at the construction site. Therefore, a PE pipe cutting device is needed. In actual use, the PE pipe to be cut is placed on two sets of base plates 2, so that it is in contact with the anti-slip pads 4. Then, the two sets of clamps 6 are rotated around the hinge point as the center axis, so that the insertion rod 9 and the rubber pad 10 are inserted into the connection hole 8. Then, the bolts 7 are screwed into the two sets of clamps 6, cooperating with the insertion rod 9 and the rubber pad 10, so that the two sets of clamps 6 and the air bag 3 form a circle. Then, the air pump 5 is started through the external controller to inflate the air bag 3. The air treatment ensures that the anti-slip pad 4 is fully in contact with the surface of the PE pipe. Then, the air pump 5 can be turned off. The inflation level of the airbag 3 can be adjusted according to the size of the PE pipe, allowing for the fixing of PE pipes of different sizes. Because the anti-slip pad 4 can increase the friction with the surface of the PE pipe, it can improve the fixing strength of the PE pipe. The cutting position is located above the baffle 11. After cutting, the sealing plug is removed, allowing the gas in the airbag 3 to be discharged outward, thereby releasing the fixing of the PE pipe. Then, the bolt 7 is unscrewed, and the two sets of clamps 6 are rotated to both sides, allowing the insertion rod 9 and the rubber pad 10 to move out of the connection hole 8 in one set of clamps 6, thus putting the clamping assembly in an open state, allowing the cut PE pipe to be removed.

[0024] Please see Figure 1-5As shown, a baffle 11 is hinged to the opening of the cutting table 1. An elastic sheet 12 is fixedly connected to the lower surface of the baffle 11. One end of the elastic sheet 12 is fixedly connected to the lower surface of the cutting table 1. A waste bin 13 is fixedly connected to the lower surface of the cutting table 1. A filter screen 14 is installed inside the waste bin 13. A fan 15 is installed on one side of the waste bin 13. An exhaust port 16 is opened on one side of the waste bin 13. A support frame 17 is fixedly connected to the upper surface of the cutting table 1. A pneumatic cylinder 18 is installed on the support frame 17. A cutting blade 19 is installed at the telescopic end of the pneumatic cylinder 18. The cutting blade 19 is located above the baffle 11. A spring 20 is installed on the upper surface of the cutting blade 19. One end of the spring 20 is installed on the support frame 17. An external controller is connected to the device. The external controller is used to control the start and stop of the air pump 5, the fan 15 and the pneumatic cylinder 18.

[0025] After the PE pipe is fixed, the pneumatic cylinder 18 is activated via an external controller to push the cutting blade 19 downwards, thus cutting the PE pipe. When the cutting blade 19 reaches its lowest position, it pushes the baffle 11 towards the waste bin 13, causing the baffle 11 to rotate around the hinge and compress the elastic sheet 12. This causes the debris generated during PE pipe cutting to be drawn into the waste bin 13 by the cutting blade 19. Simultaneously, the blower 15 is activated via the external controller. The force causing the baffle 11 to rotate opens the cutting table 1, allowing the debris to be sucked into the waste bin. Inside the waste bin 13, the filter screen 14 separates the debris from the air, allowing the debris to remain inside the waste bin 13 while the air is discharged outward from the exhaust port 16. This, in conjunction with the cutting blade 19, enhances the cleaning intensity of the debris generated during cutting. After cutting, the cutting blade 19 moves upward, reducing the pressure on the elastic sheet 12 and pushing the baffle 11 back to its original position. This keeps the top of the waste bin 13 closed, preventing debris from flowing out of the waste bin 13 and further enhancing the cleaning intensity of the debris generated during cutting, thus preventing the debris from affecting the subsequent cutting quality.

[0026] Working principle: Place the PE pipe to be cut on the two sets of base plates 2, so that the cutting position is above the baffle 11. Rotate the two sets of clamping plates 6 around the hinge point as the center axis, so that the insertion rod 9 and rubber pad 10 are inserted into the connection hole 8. Then screw the bolt 7 into the two sets of clamping plates 6, so that the two sets of clamping plates 6 and the air bag 3 form a circle. Start the air pump 5 through the external controller to inflate the air bag 3, so that the anti-slip pad 4 can be completely attached to the surface of the PE pipe. Then turn off the air pump 5 to fix the PE pipe. Start the pneumatic cylinder 18 through the external controller to push the cutting blade 19 downward to cut the PE pipe. When the cutting blade 19 moves to the bottom, the baffle 11 is closed. 1. Push the waste bin 13, so that the debris generated during PE pipe cutting is driven into the waste bin 13 by the cutting blade 19. At the same time, the fan 15 is started by the external controller, which can suck the debris into the waste bin 13. The filter screen 14 can separate the debris from the air, so that the debris stays inside the waste bin 13. The air is discharged from the exhaust port 16. In combination with the cutting blade 19, it can improve the cleaning intensity of the debris generated during cutting. After cutting, the cutting blade 19 moves upward, and the pressure on the elastic plate 12 decreases, thereby pushing the baffle 11 back to its original position, so that the top of the waste bin 13 is in a closed state, preventing the debris in the waste bin 13 from flowing out, thereby preventing the debris from affecting the subsequent cutting quality.
