Description

Technical Field

[0001] This utility model relates to the field of hose processing equipment, specifically to a dual-station hose cutting machine for hose production. Background Technology

[0002] Cross-linked polyethylene (PEX) pipe is a type of hose made of polyethylene material. The linear molecular structure of polyethylene is transformed into a three-dimensional network structure through physical and chemical methods, thereby improving the performance of polyethylene and making it widely used in various fields.

[0033] like Figures 1-9 As shown, this utility model embodiment provides a dual-station hose cutting machine for hose production, including a support 10, a mounting plate 11 on the support 10, and a rotary cutting mechanism and a separation mechanism arranged side by side from right to left on the mounting plate 11. There are two rotary cutting mechanisms and two separation mechanisms, which are respectively arranged front and rear on the mounting plate 11. The rotary cutting mechanism includes a first clamping assembly 1, a cutting assembly, and a rotating assembly. The cutting assembly includes a first support plate 12, a protective cover 13, a drive structure, a horizontal transmission structure 2, a transmission joint structure 3, a vertical transmission structure 4, and an electric cutting structure 5. One side of the first support plate 12 is connected to the protective cover 13. The drive structure is arranged on the first support plate 12. The horizontal transmission structure 2, the transmission joint structure 3, the vertical transmission structure 4, and the electric cutting structure 5 are disposed inside the protective cover 13. The rotating assembly includes a first sleeve 14, one end of which is mounted on a circular hole 15 in a first support plate 12, and the other end extends to an electric cutting structure 5. A second sleeve 16 is fitted onto the surface of the first sleeve 14, and the outlet end of the second sleeve 16 is on the same vertical cross section as the outlet end of the first sleeve 14. A transmission structure 6 is provided on the second sleeve 16, and the transmission structure 6 passes through a through-hole 25 on a mounting plate 11 and is connected to the power structure for transmission. The separating mechanism includes a second clamping assembly 7, a moving assembly, and a guiding assembly 9. The second clamping assembly 7 is arranged side by side with the first clamping assembly 1, and the second clamping assembly 7 is slidably connected to the moving assembly. The guiding assembly 9 is located on the side of the second clamping assembly 7 away from the first clamping assembly 1. An installation rod 17 is installed on the mounting plate 11 between the two rotating cutting mechanisms, and an automatic control assembly 18 is provided on the installation rod 17.

[0034] Specifically, the automation control component 18 controls the entire dual-station tube cutting machine. The first clamping component 1 clamps and fixes the rubber tube 26 for cutting. The drive structure drives the horizontal transmission structure 2 to move horizontally. The transmission joint structure 3 transmits the power of the horizontal transmission structure 2 to the vertical transmission structure 4 as the power for the vertical movement of the electric cutting structure 5. Under the vertical movement power, the distance between the electric cutting structure 5 and the rubber tube 26 is adjusted, and the top surface of the rubber tube 26 is cut. At the same time, the electric cutting structure 5 moves the surface of the rubber tube 26 under the action of the rotating component, thereby cutting the rubber tube 26. The second clamping component 7 clamps and fixes the cut rubber tube 26. The moving component is used to move the second clamping component 7 and remove the cut rubber tube 26. The guiding component 9 is used to guide the movement direction of the cut rubber tube 26.

[0035] In this embodiment, as Figures 1-4 As shown, the driving structure is a cylinder 19. The cylinder 19 is mounted on the side of the first support plate 12 away from the protective cover 13 by a fixing plate. The top of the first support plate 12 is provided with a through groove that communicates with the inside of the protective cover 13. The piston rod of the cylinder 19 passes through the through groove and is connected to the horizontal transmission structure 2.

[0036] Specifically, cylinder 19 drives the piston to move back and forth, thereby causing the horizontal transmission structure 2 to move back and forth.

[0037] In this embodiment, as Figure 4 As shown, the horizontal transmission structure 2 includes an inverted U-shaped frame 201. The top of the inverted U-shaped frame 201 is movably connected to the piston rod of the cylinder 19. The bottom ends of both sides of the inverted U-shaped frame 201 are movably connected to the other side of the first support plate 12 away from the cylinder 19. One end of the first connecting block 202 is rotatably connected to both sides of the inverted U-shaped frame 201. The other end of the first connecting block 202 is fixedly connected to the outside of the ring 203. A limit ring 204 is provided on the inner side of the ring 203 near the first support plate 12. A convex cylindrical ring 205 is sleeved on the second sleeve 16. The ring 203 is sleeved on the smaller diameter cylindrical ring of the convex cylindrical ring 205. The end of the larger diameter cylindrical ring of the convex cylindrical ring 205 is connected to a first mounting plate 206. Two U-shaped grooves 207 are symmetrically opened at the upper and lower ends of the first mounting plate 206. Movable rods are installed on the U-shaped grooves 207.

[0038] Specifically, the top of the inverted U-shaped frame 201 moves back and forth under the drive of the cylinder 19. Since the first connecting block 202 is rotatably connected to both sides of the inverted U-shaped frame 201, the first connecting block 202 moves in the opposite direction to the movement of the top of the inverted U-shaped frame 201. The ring 203 connected to the first connecting block 202 also moves back and forth in the same direction as the first connecting block 202. Under the limiting action of the limiting ring 204, the ring 203 drives the convex cylindrical ring 205 to move back and forth on the second sleeve 16. The forward movement of the convex cylindrical ring 205 drives the first mounting plate 206 connected to it to move back and forth.

[0039] In this embodiment, as Figure 4 As shown, the transmission joint structure 3 includes a second mounting plate 301 and four rotating plates 302. The second mounting plate 301 is symmetrically connected to the end of the second sleeve 16 away from the first support plate 12, and the second mounting plate 301 and the second sleeve 16 are integrally formed. The four rotating plates 302 are rotatably connected to the front and rear sides of the upper and lower ends of the second mounting plate 301, respectively. One end of the rotating plate (302) is provided with a movable groove 303, and a sliding ring 304 connected to the movable rod is slidably connected in the movable groove 303.

[0040] Specifically, the four movable rods symmetrically arranged on both sides of the upper and lower ends of the first mounting plate 206 move within the movable grooves 303 of the four rotating plates 302 respectively under the action of the first mounting plate 206.

[0041] In this embodiment, as Figure 4 As shown, the vertical transmission structure 4 includes two first mounting blocks 401 and two second mounting blocks 402 corresponding to the first mounting blocks 401. The two second mounting blocks 402 are respectively located at the upper and lower ends of the side of the second mounting plate 301 away from the second sleeve 16. The first mounting blocks 401 are located between the two rotating plates 302. A sliding groove 403 is provided on the side of the first mounting block 401 away from the second mounting plate 301. The sliding groove 403 is slidably connected to the I-shaped slider 404. The side of the I-shaped slider 404 away from the sliding groove 403 is connected to the second mounting block 402 through the mounting structure 405. The two sides of the side of the second mounting block 402 away from the I-shaped slider 404 are respectively rotatably connected to one end of the second connecting block 406. The other end of the second connecting block 406 is rotatably connected to the end of the rotating plate 302 away from the movable groove 303.

[0042] Specifically, since the rotating plate 302 is rotatably connected to the second mounting plate 301, the two rotating plates 302 located above the second mounting plate 301 are rotatably connected to the second connecting block 406 through the other end under the action of the moving rod in the movable groove 303 at one end. The second connecting block 406 is rotatably connected to the second mounting block 402, so that the second mounting block 402 pushes the I-shaped slider 404 to slide up and down in the groove 403 of the first mounting block 401.

[0043] In this embodiment, as Figure 5 As shown, the electric cutting structure 5 includes a drive block 501 and a sliding mounting block 502. The I-shaped slider 404 above the second mounting plate 301 has an extension plate on one side inside the slide groove 403. The extension plate is connected to the drive block 501. A rotating motor is installed inside the drive block 501. The rotating shaft of the rotating motor is connected to the cutting blade 503. One end of the I-shaped slider 404 below the second mounting plate 301 is connected to the sliding mounting block 502. Four pulleys 504 are installed on the sliding mounting block 502 directly below the cutting blade 503.

[0044] Specifically, under the sliding action of the sliding groove 403, the I-shaped sliders 404 above and below the second mounting plate 301 slide up and down, the cutting blade 503 installed on the extension plate of the upper I-shaped slider 404 slides up and down, and the four pulleys 504 installed at one end of the lower I-shaped slider 404 slide up and down, thereby adjusting the distance between the cutting blade 503, the four pulleys 504 and the tube 26, so that the tube 26 can fit against the four pulleys 504, and the rotating cutting blade 503 can cut the top of the surface of the tube 26.

[0045] In this embodiment, as Figure 2 As shown, the power structure is a drive motor 20, which is mounted on the bracket 10. The transmission structure 6 includes a first pulley 601 mounted on the second sleeve 16, and a second pulley 602 mounted on the shaft of the drive motor 20. The second pulley 602 is connected to the first pulley 601 via a synchronous belt 603.

[0046] Specifically, the drive motor 20 drives the rotating shaft to rotate, which in turn drives the second pulley 602 to rotate. Under the transmission of the synchronous belt 603, the second pulley 602 drives the first pulley 601 connected to the second sleeve 16 to rotate. The rotation of the first pulley 601 drives the second mounting plate 301 connected to the second sleeve 16 to rotate around the first sleeve 14, thereby causing the cutting blade 503 and the four pulleys 504 slidably connected to the first mounting block 401 to also rotate around the first sleeve 14. Thus, the electric cutting structure 5 moves on the surface of the hose 26 through the four pulleys 504 while cutting the hose 26 around the surface of the hose 26 through the cutting blade 503.

[0047] In this embodiment, as Figure 7As shown, the first clamping assembly 1 includes a first semi-circular clamping member 101 mounted on the mounting plate 11 and a second semi-circular clamping member 102 located directly above the first semi-circular clamping member 101. The top of the first semi-circular clamping member 101 is respectively equipped with first sliding rods 103 on both sides of the clamping surface. The second semi-circular clamping member 102 is provided with two first sliding grooves that are slidably connected to the first sliding rods 103. The two first sliding rods 103 pass through the corresponding first sliding grooves and are connected to both sides of the bottom surface of the third mounting plate 104. A first cylinder 105 is mounted on the third mounting plate 104. The telescopic rod of the first cylinder 105 passes through the third mounting plate 104 and is fixedly connected to the second semi-circular clamping member 102.

[0048] Specifically, the second semi-circular clamping member 102 moves vertically up and down under the drive of the first cylinder 105 and the sliding action of the first sliding rod 103 in the first sliding groove, and clamps and fixes the passing rubber tube 26 under the support of the first semi-circular clamping member 101.

[0049] In this embodiment, as Figure 6 As shown, the moving component consists of two guide rails 8 fixed on the mounting plate 11. The second clamping component 7 includes a sliding seat 701 slidably connected to the guide rails 8. A third semi-circular clamping member 702 is mounted on the sliding seat 701. A fourth semi-circular clamping member 703 is positioned directly above the third semi-circular clamping member 702. Second sliding rods 704 are respectively mounted on both sides of the clamping surface at the top of the third semi-circular clamping member 702. The fourth semi-circular clamping member 703 has two second sliding grooves inside that are slidably connected to the second sliding rods 704. The two second sliding rods 704 respectively pass through the corresponding second sliding grooves and connect to both sides of the bottom surface of the fourth mounting plate 705. The fourth mounting plate 705... A second cylinder 706 is mounted on the plate. The telescopic rod of the second cylinder 706 passes through the fourth mounting plate 705 and is fixedly connected to the fourth semi-circular clamping member 703. The guide assembly 9 includes a second support plate 901 mounted on the mounting plate 11. A guide tube 902 is mounted on the second support plate 901. A third cylinder 903 is mounted on one side of the bottom of the second support plate 901. The piston rod of the third cylinder 903 is connected to the sliding seat 701. The central axis of the guide tube 902 coincides with the central axis of the first sleeve 14. The support height of the guide tube 902 is the same as the support height of the second semi-circular clamping member 102, the fourth semi-circular clamping member 703, and the first sleeve 14.

[0050] Specifically, the fourth semi-circular clamping member 703 moves vertically up and down under the drive of the second cylinder 706 and the sliding action of the second sliding rod 704 in the second sliding groove. Under the support of the third semi-circular clamping member 702, it clamps and fixes the cut rubber tube 26. Subsequently, the third cylinder 903 drives the sliding seat 701 to move away from the first clamping component 1 under the action of the guide rail 8. That is, it drives the second clamping component 7 to move away from the first clamping component 1. The cut rubber tube 26 also moves away from the first clamping component 1, thereby separating the cut rubber tube 26 from the original rubber tube 26.

[0051] In this embodiment, as Figure 1 As shown, the bracket 10 has detection doors 21 on the front and rear sides, and protective plates 22 on the left and right sides. The fifth mounting plate for installing the cooling fan is provided on the inner side of the left protective plate 22. The left protective plate 22 has an air outlet 23 for the cooling fan to discharge hot air and several heat dissipation holes 24.

[0052] Specifically, by setting up the detection door 21, it is convenient to detect the drive motor 20. By setting up the cooling fan outlet 23 and the heat dissipation port 24 on the protective plate 22, the heat generated by the device is discharged to prevent the device from overheating.

[0053] In this embodiment, the tubing 26 is a cross-linked polyethylene (PEX) tube with a size of 1 inch.

[0054] Specifically, this device is suitable for cutting 1-inch cross-linked polyethylene (PEX) tubes and other types of tubing 26.

[0055] The working principle of this embodiment is as follows: Before use, a 1-inch cross-linked polyethylene pipe is passed through the first sleeve 14, the first clamping component 1, the second clamping component 7 and the guide tube 902 in sequence. The first cylinder 105 is controlled by the automatic control component 18 to control the first semi-circular clamping component 101 to move downward. Under the support of the second semi-circular clamping component 102, the cross-linked polyethylene pipe is clamped and fixed.

[0056] During cutting, the cylinder 19, controlled by the automated control component 18, drives the piston to move backward. Under the transmission of the inverted U-shaped frame 201 and the first connecting block 202, the ring 203 moves forward on the second sleeve 16. The ring 203, limited by the limiting ring 204, drives the convex cylindrical ring 205 forward on the second sleeve 16. The forward movement of the convex cylindrical ring 205 causes the first mounting plate 206 connected to it to move forward. Four movable rods symmetrically arranged on both sides of the upper and lower ends of the first mounting plate 206 move inward within the movable grooves 303 of the four rotating plates 302 under the action of the forward movement of the first mounting plate 206. Since the rotating plate 302 is rotatably connected to the second mounting plate 301, the two rotating plates 302 located above the second mounting plate 301, under the action of the movable rod moving inward in one end of the movable groove 303, are rotatably connected to the second connecting block 406 through the other end. The second connecting block 406 is rotatably connected to the second mounting block 402, so that the second mounting block 402 pushes the I-shaped slider 404 to slide downward in the slide groove 403 of the first mounting block 401. The cutting blade 503 installed on the extension plate of the I-shaped slider 404 can also slide downward. The two rotating plates 302 located below the second mounting plate 301, in one end of the movable groove 303... Under the action of the movable rod, it is rotatably connected to the second connecting block 406 at the other end. The second connecting block 406 is rotatably connected to the second mounting block 402, so that the second mounting block 402 pushes the I-shaped slider 404 to slide upward in the slide groove 403 of the first mounting block 401. The four pulleys 504 installed at one end of the I-shaped slider 404 can also slide upward, thereby adjusting the distance between the cutting blade 503, the four pulleys 504 and the cross-linked polyethylene pipe, so that the cross-linked polyethylene pipe can fit against the four pulleys 504. The rotating cutting blade 503 can cut the top of the surface of the cross-linked polyethylene pipe. At the same time, through the automatic control component 1 8. The control drive motor 20 drives the second pulley 602 to rotate. The rotation of the second pulley 602 drives the first pulley 601 connected to the second sleeve 16 to rotate through the synchronous belt 603. The rotation of the first pulley 601 drives the second mounting plate 301 connected to the second sleeve 16 to rotate around the first sleeve 14, so that the cutting blade 503 and the four pulleys 504 slidably connected to the first mounting block 401 also rotate around the first sleeve 14. Thus, the electric cutting structure 5 moves on the surface of the cross-linked polyethylene pipe through the four pulleys 504 while cutting the surface of the cross-linked polyethylene pipe around the cross-linked polyethylene pipe through the cutting blade 503.

[0057] After the cross-linked polyethylene pipe is completely cut, the automatic control component 18 stops the drive motor 20 from rotating the electric cutting structure. The automatic control component 18 then controls the cylinder 19 to drive the piston forward. Under the transmission of the inverted U-shaped frame 201 and the first connecting block 202, the ring 203 moves backward on the second sleeve 16. Under the limiting action of the limiting ring 204, the ring 203 drives the convex cylindrical ring 205 to move backward on the second sleeve 16. The forward movement of the convex cylindrical ring 205 causes the first mounting plate 206 connected to it to move backward. Four movable rods symmetrically arranged on both sides of the upper and lower ends of the first mounting plate 206 move outward within the movable grooves 303 of the four rotating plates 302 as the first mounting plate 206 moves backward. Since the rotating plates 302 are rotatably connected to the second mounting plate 301, the two rotating plates 302 located above the second mounting plate 301, under the action of the movable rods moving outward within the movable grooves 303 at one end, are rotatably connected to the second connecting block 406 through their other ends. The second connecting block 406 is rotatably connected to the second mounting block 402, thus making the second mounting block... 402 pushes the I-shaped slider 404 to slide upward on the groove 403 of the first mounting block 401. The cutting blade 503 mounted on the extension plate of the I-shaped slider 404 can also slide upward, so that the cutting blade 503 is away from the cutting surface. At the same time, the automatic control component 18 controls the first cylinder 105 to drive the first semi-circular clamping member 101 to move upward, and controls the second cylinder 706 to drive the third semi-circular clamping member 702 to move downward. The first clamping component 1 no longer clamps the cross-linked polyethylene pipe, but the second clamping component 7 clamps the cross-linked polyethylene pipe. Then, the automatic control component 18 controls the third cylinder 903 to drive the sliding seat 701 to move away from the first clamping component 1 under the action of the guide rail 8. That is, it drives the second clamping component 7 to move away from the first clamping component 1. The cut cross-linked polyethylene pipe also moves away from the first clamping component 1, thereby separating the cut cross-linked polyethylene pipe from the original cross-linked polyethylene pipe. This avoids the problem of the cutting blade 503 overheating during continuous cutting by the electric cutting blade, which causes micro-deformation of the pipe cutting end.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
