Description

Technical Field

[0001] This utility model relates to the field of hose processing equipment, specifically to a 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.

[0003] Existing hose cutting machines mainly use electric cutters. Because electric cutters have high rotation speed and high torque, they are prone to overheating during continuous cutting. The heat of the cutter can cause slight deformation at the cut end of the hose. In addition, the hose distance needs to be manually controlled before the hose is cut to a fixed length. It is inconvenient to adjust different hose cutting lengths, and the degree of automation is low. Utility Model Content

[0014] Optionally, the first clamping assembly includes a first semi-circular clamping member mounted on the base and a second semi-circular clamping member located directly above the first semi-circular clamping member.

[0016] Optionally, the bracket has several support feet at the bottom, detection doors on the front and rear sides, and protective plates on the left and right sides.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model pre-sets the position of the second clamping component on the second guide rail according to the length of the cross-linked polyethylene pipe to be cut by the automatic control component. The guide component guides the cutting tube into the second clamping component and the first clamping component before entering directly below the cutting blade. The position of the second clamping component on the second guide rail is adjusted by the displacement sensor according to the length of the cutting tube to be cut. At the same time, the position sensor detects the position of the second clamping component on the second guide rail as the original position before feeding, thereby realizing the adjustment of the cutting distance. The cutting tube is clamped and fixed by the second clamping component. Under the action of the third cylinder, the second clamping component moves towards the direction of the rotary cutting mechanism and moves the front end of the cutting tube into the first sleeve, thereby completing the fixed-length feeding of the cutting tube. After feeding, the cutting tube is clamped and fixed by the first clamping component. The second clamping component does not need to clamp and fix the cutting tube. Then, the cutting component and the rotary component rotate and cut the surface of the tube, thereby realizing the fixed-length cutting of the cutting tube. Such cutting length can be adjusted and the fixed-length cutting is automated, which greatly improves the automation level of the tube cutting machine.

[0019] (2) During cutting, this utility model adjusts the relative positions of the cutting blade, pulley, and hose of the electric cutting structure through a drive structure, a horizontal transmission structure, a transmission joint structure, and a vertical transmission structure. The pulley is moved to the top surface of the hose and contacts it, while the cutting blade moves to the top surface of the hose and cuts it. Subsequently, the cutting assembly is rotated by a rotating component, causing the pulley to move around the hose surface while the rotating cutting blade cuts the hose surface, thus achieving rapid cutting of the hose. During cutting, the second clamping component no longer clamps and fixes the hose, and under the detection of a position sensor, the automatic control component controls it to move along the second guide rail back to its original position. After cutting, the drive structure... The horizontal transmission structure, transmission joint structure, and vertical transmission structure adjust the relative position between the cutting blade, pulley, and hose, moving the cutting blade and pulley away from the hose surface. Then, the second clamping assembly, returning to its original position, clamps and fixes the cut hose. Under the action of the third cylinder, the second clamping assembly moves on the second guide rail towards the rotary cutting mechanism and moves the front end of the cut hose into the first sleeve. At this time, the cut hose inside the first sleeve is pushed out from the outlet and discharged along the inclined U-shaped groove. This method quickly cuts the hose and separates the cut tube, improving cutting efficiency and avoiding the problem of micro-deformation of the pipe cutting end caused by overheating of the cutting blade during continuous electric cutting.

[0036] like Figures 1-10 As shown, this utility model embodiment provides a hose cutting machine for hose production, including a bracket 8, a mounting plate 9 on the bracket 8, a feeding mechanism and a rotary cutting mechanism respectively arranged on the mounting plate 9 from left to right, a mounting rod 10 installed on the mounting plate 9 behind the feeding mechanism, and an automatic control component 11 for controlling the hose cutting machine is provided on the mounting rod 10;

[0037] The feeding mechanism includes a base 12 mounted on a mounting plate 9. From left to right, a guide assembly, a moving assembly, and a first clamping assembly 1 are respectively arranged on the base 12. A second clamping assembly 2 is slidably connected to the moving assembly. A position sensor 13 and a displacement sensor 14 are respectively arranged on the same side of the base 12 as the moving assembly. The position sensor 13 is mounted on the side of the base 12 away from the first clamping assembly 1, and the displacement sensor 14 is mounted on the side of the base 12 close to the first clamping assembly 1. Both the position sensor 13 and the displacement sensor 14 are electrically connected to the input terminal of the automation control assembly 11.

[0038] The rotary cutting mechanism includes a cutting assembly and a rotating assembly. The cutting assembly includes a first support plate 15, a protective cover 16, a drive structure, a horizontal transmission structure 3, a transmission joint structure 4, a vertical transmission structure 5, an electric cutting structure 6, and a discharge structure. One side of the first support plate 15 is connected to the protective cover 16. The drive structure is mounted on the first support plate 15. The horizontal transmission structure 3, the transmission joint structure 4, the vertical transmission structure 5, and the electric cutting structure 6 are disposed inside the protective cover 16. The drive structure drives the horizontal transmission structure 3 to move horizontally, and the transmission joint structure 4 transmits the power of the horizontal movement of the horizontal transmission structure 3 to the vertical transmission structure 6. The moving structure 5 serves as the power source for the vertical movement of the electric cutting structure 6. The electric cutting structure 6 rotates under the drive of the rotating component. The first support plate 15 has a discharge port 17 at its center. The discharge structure is located below the discharge port 17 and is installed on the side of the first support plate 15 away from the protective cover 16. The rotating component includes a first sleeve 18. One end of the first sleeve 18 is installed on the discharge port 17, and the other end extends to the electric cutting structure 6. A second sleeve 19 is sleeved on the surface of the first sleeve 18. A transmission structure 7 is provided on the second sleeve 19. The transmission structure 7 passes through the opening on the mounting plate 9 and is connected to the power structure for transmission.

[0039] Specifically, the automation control component 11 controls the entire dual-station tube cutting machine. The guide component guides the hose, which passes through the second clamping component 2 and the first clamping component 1. Based on the desired cutting length of the hose, the displacement sensor 14 adjusts the position of the second clamping component 2 on the moving component. Simultaneously, the position sensor 13 detects the position of the second clamping component 2 on the moving component as its initial position before feeding, thus adjusting the cutting distance. The second clamping component 2 clamps and fixes the hose. Under the action of the moving component, the second clamping component 2 moves towards the rotary cutting mechanism and... The front end of the hose is moved into the first sleeve 18 to complete the fixed-length feeding of the hose. The first clamping assembly 1 clamps and fixes the hose for cutting. The drive structure drives the horizontal transmission structure 3 to move horizontally. The transmission joint structure 4 transmits the power of the horizontal transmission structure 3 to the vertical transmission structure 5 as the power for the vertical movement of the electric cutting structure 6. Under the vertical movement power, the distance between the electric cutting structure 6 and the hose is adjusted, and the top of the hose surface is cut. At the same time, the surface of the hose moves under the action of the rotating assembly, thereby cutting the hose.

[0040] In this embodiment, as Figures 2-4 As shown, the drive structure includes two cylinders 20, which are symmetrically mounted on the first support plate 15, and their piston rods extend into the interior of the protective cover 16. The discharge structure is an inclined U-shaped groove 21, which is located directly below the discharge port 17 and is mounted on the side of the first support plate 15 away from the protective cover 16.

[0041] Specifically, two cylinders 20 drive the cutting assembly to make it work more stably; the inclined U-shaped groove 21 serves as the discharge structure, allowing the cut tube to be discharged from the discharge port 17 without any power.

[0042] In this embodiment, as Figure 6 As shown, the horizontal transmission structure 3 includes a sliding plate 301 with a circular hole at its center. A connecting post 302 passes through the circular hole and is mounted on the circular hole via a ring 303. Four hollow posts 304 are symmetrically mounted on the sliding plate 301. One side of the sliding plate 301 is fixedly connected to the end of the piston rod of the cylinder 20. A limiting ring 305 with the same center as the circular hole is mounted on the other side of the sliding plate 301. Two mounting posts 306 are symmetrically arranged on one side of the sliding plate 301 near the limiting ring 305. The mounting posts 306 are mounted on the mounting plate 9, and two sliding rods 307 are respectively arranged on the side of the mounting posts 306 facing the sliding plate 301. The four sliding rods 307 pass through the four hollow posts 304 one by one and are fixedly connected to the first support plate 15. The two sliding rods 307 mounted on the same mounting post 306 are symmetrically arranged about the piston rod of the cylinder 20 on the same side as the mounting post 306.

[0043] Specifically, the four sliding rods 307 and the four hollow pillars 304 that are set one-to-one with each other enable the sliding plate 301 to slide linearly under the push of the cylinder 20.

[0044] In this embodiment, as Figure 5 As shown, the transmission joint structure 4 includes a first connecting ring 401 connected to the end of the sliding plate 301 away from the connecting post 302. Two first connecting plates 402 are symmetrically arranged on the first connecting ring 401. Push plates 403 are symmetrically connected to both sides of the first connecting plate 402. An elongated hole 404 is opened on the push plate 403, and the elongated hole 404 is inclined on the push plate 403. The front end of the elongated hole 404 is close to the outer side of the push plate 403, and the rear end of the elongated hole 404 is close to the inner side of the push plate 403.

[0045] In this embodiment, as Figure 7 As shown, the electric cutting structure 6 includes two mounting blocks 601 symmetrically arranged about the first sleeve 18. Sliding rings 602 are symmetrically rotatably connected to both sides of the mounting blocks 601. The sliding rings 602 are slidably connected in the elongated hole 404.

[0046] In this embodiment, as Figure 7 As shown, the vertical transmission structure 5 includes a second connecting ring 501 connected to the end of the second sleeve 19. The second connecting ring 501 is symmetrically provided with two second connecting plates 502. A first guide rail 503 is installed on the second connecting plate 502. The bottom of the mounting block 601 is connected to a sliding groove 504 that is slidably connected to the first guide rail 503.

[0047] Specifically, the front end of the elongated hole 404 is close to the outer side of the push plate 403, and the rear end of the elongated hole 404 is close to the inner side of the push plate 403. The two sides of the mounting block 601 are symmetrically connected to the sliding ring 602. The sliding ring 602 is slidably connected in the elongated hole 404, so that the two mounting blocks 601 can move inside and outside about the center of the second connecting ring 501 when the push plate 403 moves back and forth. This causes the cutting blade 606 at the end of the first connecting block 603 to move inside and outside about the center of the second connecting ring 501, and the pulley 609 at the end of the second connecting block 607 to move inside and outside about the center of the second connecting ring 501.

[0048] In this embodiment, as Figure 3 As shown, the power structure is a drive motor 22, which is mounted on the bottom of the mounting plate 9. The transmission structure 7 includes a first pulley 701 mounted on the second sleeve 19, and a second pulley 702 mounted on the shaft of the drive motor 22. The second pulley 702 is connected to the first pulley 701 via a synchronous belt 703.

[0049] Specifically, the drive motor 22 drives the rotating shaft to rotate, and the rotating shaft drives the second pulley 702 to rotate. Under the transmission action of the synchronous belt 703, the second pulley 702 drives the first pulley 701 connected to the second sleeve 19 to rotate. The rotation of the first pulley 701 drives the second connecting ring 501 connected to the second sleeve 19 to rotate around the first sleeve 18. The mounting block 601 slidably connected to the second connecting ring 501 rotates in turn.

[0050] In this embodiment, as Figure 9 As shown, the first clamping assembly 1 includes a first semi-circular clamping member 101 mounted on the base 12 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 has two first sliding grooves inside 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 first mounting plate 104. A first cylinder 105 is mounted on the first mounting plate 104. The telescopic rod of the first cylinder 105 passes through the first mounting plate 104 and is fixedly connected to the second semi-circular clamping member 102.

[0051] 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 under the support of the first semi-circular clamping member 101.

[0052] In this embodiment, as Figure 10 As shown, the moving component consists of two second guide rails 23 fixed on the base 12. The second clamping component 2 includes a sliding seat 201 slidably connected to the second guide rails 23. A third semi-circular clamping member 202 is mounted on the sliding seat 201. A fourth semi-circular clamping member 203 is disposed directly above the third semi-circular clamping member 202. Second sliding rods 204 are respectively mounted on both sides of the clamping surface at the top of the third semi-circular clamping member 202. The fourth semi-circular clamping member 203 has two second sliding grooves inside that are slidably connected to the second sliding rods 204. The two second sliding rods 204 respectively pass through the corresponding second sliding grooves and connect to both sides of the bottom surface of the second mounting plate 205. A second cylinder 206 is mounted on the second mounting plate 205. The telescopic rod of the second cylinder 206 passes through the second mounting plate 205 and is fixedly connected to the fourth semi-circular clamping member 203. The guide assembly includes a second support plate 24 mounted on the base 12. A guide tube 25 is mounted on the second support plate 24. A third cylinder 26 is mounted on one side of the bottom of the second support plate 24. The piston rod of the third cylinder 26 is connected to the sliding seat 201. The central axis of the guide tube 25 coincides with the central axis of the first sleeve 18. The support height of the guide tube 25 is the same as the support height of the second semi-circular clamping member 102, the fourth semi-circular clamping member 203, and the first sleeve 18.

[0053] Specifically, the fourth semi-circular clamping member 203 moves vertically up and down under the drive of the second cylinder 206 and the sliding action of the second sliding rod 204 in the second sliding groove. Under the support of the third semi-circular clamping member 202, it clamps and fixes the hose. Subsequently, the third cylinder 26 drives the sliding seat 201 to move towards the rotary cutting mechanism under the action of the second guide rail 23. That is, it drives the second clamping assembly 2 to move towards the rotary cutting mechanism. The hose also moves towards the rotary cutting mechanism, thereby realizing feeding near the rotary cutting mechanism.

[0054] In this embodiment, as Figure 1 and Figure 2 As shown, the bottom of the bracket 8 is provided with several support feet 27, the front and rear sides of the bracket 8 are provided with detection doors 28, and the left and right sides of the bracket 8 are provided with protective plates 29.

[0055] Specifically, by setting up the detection gate 28, it is convenient to detect the drive motor 22.

[0056] In this embodiment, the tubing is a cross-linked polyethylene (PEX) tube with a size of 3 inches.

[0057] Specifically, this device is suitable for cutting 3-inch cross-linked polyethylene (PEX) tubes and other types of tubing.

[0058] The working principle of this embodiment is as follows: Before use, the operator pre-sets the position of the second clamping component 2 on the second guide rail 23 according to the length of the cross-linked polyethylene pipe to be cut on the automation control component 11. The 3-inch cross-linked polyethylene pipe is then passed through the guide tube 25, the second clamping component 2, and the first clamping component 1 until it is directly below the cutting blade 606. At the same time, the position sensor 13 detects the position of the second clamping component 2 on the second guide rail 23 and feeds it back to the automation control component 11 as the original position of the second clamping component 2. The automation control component 11 then controls the second cylinder 206 to drive the third semi-circular clamping member 202 to move downward. Under the support of the fourth semi-circular clamping member 203, the cross-linked polyethylene pipe is clamped and fixed. Then, the third cylinder 206 is controlled to move downward. Cylinder 26 drives the sliding seat 201 to move closer to the rotary cutting mechanism on the second guide rail 23, which in turn moves the cross-linked polyethylene pipe held by the second clamping component 2 closer to the rotary cutting mechanism. At the same time, displacement sensor 14 detects the position of the second clamping component 2 on the second guide rail 23 and feeds it back to the automation control component 11. Once the second clamping component 2 reaches the position preset on the second guide rail 23, the third cylinder 26 stops driving the sliding seat 201 and controls the first cylinder 105 to drive the first semi-circular clamping member 101 to move downward. Under the support of the second semi-circular clamping member 102, the cross-linked polyethylene pipe is clamped and fixed. Meanwhile, the second cylinder 206 drives the third semi-circular clamping member 202 to move upward and stops clamping and fixing the cross-linked polyethylene pipe.

[0059] During cutting, the automatic control component 11 controls two cylinders 20 to simultaneously drive the piston rods to move backward, causing the sliding plate 301 connected to the piston rods to move on the second sleeve 19. Simultaneously, the hollow column 304 connected to the sliding plate 301 slides on the sliding rod 307 located between the support plate and the mounting column 306, causing the sliding plate 301 to move linearly backward on the second sleeve 19. The moving sliding plate 301, driven by the connecting column 302, drives the first connecting ring 401 to move backward. Symmetrically arranged on the first connecting ring... The first connecting plates 402 on both sides of 401 also move backward. Since the front end of the elongated hole 404 is close to the outer side of the push plate 403 and the rear end of the elongated hole 404 is close to the inner side of the push plate 403, the two mounting blocks 601 move inward about the center of the second connecting ring 501. This causes the cutting blade 606 at the end of the first connecting block 603 to move toward the surface of the cross-linked polyethylene pipe until the cutting blade 606 cuts into its surface. The pulley 609 at the end of the second connecting block 607 moves toward the surface of the cross-linked polyethylene pipe until the pulley 609 abuts against its surface. Meanwhile, the control motor 604 rotates the cutting blade 606, and the control drive motor 22 drives the second pulley 702 to rotate. The rotation of the second pulley 702 drives the first pulley 701 connected to the second sleeve 19 to rotate through the synchronous belt 703. The rotation of the first pulley 701 drives the second connecting ring 501 connected to the second sleeve 19 to rotate around the first sleeve 18, so that the rotating cutting blade 606 and pulley 609 also rotate around the first sleeve 18. Thus, the electric cutting structure 6 moves around the surface of the cross-linked polyethylene pipe through the pulley 609 while cutting the surface of the cross-linked polyethylene pipe through the cutting blade 606. The control cylinder 26 drives the sliding seat 201 to move away from the rotating cutting mechanism on the second guide rail 23, driving the second clamping assembly 2 to move away from the rotating cutting mechanism until it returns to the original position. Then, the control cylinder 206 drives the third semi-circular clamping member 202 to move downward. Under the support of the fourth semi-circular clamping member 203, the cut cross-linked polyethylene pipe is clamped and fixed.

[0060] After the cross-linked polyethylene pipe is completely cut, the automatic control component 11 stops the drive motor 22 and the rotation motor 604. At the same time, the two cylinders 20 are controlled to drive the piston rods forward, causing the sliding plate 301 connected to the piston rod to move on the second sleeve 19. Simultaneously, the hollow column 304 connected to the sliding plate 301 slides on the sliding rod 307 located between the support plate and the mounting column 306, causing the sliding plate 301 to move forward linearly on the second sleeve 19. The moving sliding plate 301, driven by the connecting column 302, drives the first connecting ring 401 to move forward. The first connecting plates 402, symmetrically arranged on both sides of the first connecting ring 401, also move forward. Since the front end of the elongated hole 404 is close to the outer side of the push plate 403 and the rear end of the elongated hole 404 is close to the inner side of the push plate 403, the two mounting blocks 601 move outward about the center of the second connecting ring 501. This causes the cutting blade 606 to move away from the surface of the cross-linked polyethylene pipe until the cutting blade 606 disengages from its surface. The pulley 609 at the end of the second connecting block 607 moves away from the surface of the cross-linked polyethylene pipe until the pulley 609 disengages from its surface. Then, the third cylinder 2 is controlled. The drive slide block 201 moves closer to the rotary cutting mechanism on the second guide rail 23, causing the cross-linked polyethylene pipe being cut, held by the second clamping assembly 2, to move closer to the rotary cutting mechanism. Simultaneously, the displacement sensor 14 detects the position of the second clamping assembly 2 on the second guide rail 23 and feeds it back to the automation control assembly 11. Once the second clamping assembly 2 reaches the pre-set position on the second guide rail 23, the third cylinder 26 stops driving the slide block 201 and controls the first cylinder 105 to drive the first semi-circular clamping member 101 downwards. Under the support of the second semi-circular clamping member 102... The cross-linked polyethylene pipe is clamped and fixed, while the second cylinder 206 drives the third semi-circular clamping member 202 to move upward, and then the cross-linked polyethylene pipe to be cut is no longer clamped and fixed. Then, the rotary cutting mechanism is controlled by the automatic control component 11 to cut the cross-linked polyethylene pipe a second time. At the same time, the cross-linked polyethylene pipe that was cut off in the first time is impacted by the cross-linked polyethylene pipe being cut and moves to the discharge port 17. Under the guidance of the inclined U-shaped groove 21, it is discharged. By repeating this operation, the rotary cutting mechanism cuts the long cross-linked polyethylene pipe into several short pipes of the same material of equal length.

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.
