Description

Technical Field

[0001] This application relates to the field of hose production equipment, and in particular to a hose cutting device. Background Technology

[0002] Flexible tubing is mainly used as a protective conduit for wires, cables, and signal wires in automated instruments.

[0003] When cutting flexible rubber tubes, the tube is usually directly fed to a circular cutter for cutting. However, due to the strong elasticity of the flexible rubber tube, it will deform during the cutting process, resulting in an uneven cross-section at the end of the tube. This requires secondary trimming, which is usually done manually by workers. This greatly affects the quality and accuracy of the cutting of the tube end and has shortcomings. Utility Model Content

[0004] In order to improve the problem of uneven cross-section caused by deformation during hose cutting, this application provides a hose cutting device.

[0005] The flexible hose cutting device provided in this application adopts the following technical solution: A flexible rubber hose cutting device includes a machine body, a feeding bracket on the machine body, a material tray rotatably mounted on the feeding bracket, a flexible rubber hose wound on the material tray, an upper pressure roller and a lower support roller rotatably mounted on the machine body, the upper pressure roller being directly above the lower support roller, the flexible rubber hose passing between the upper pressure roller and the lower support roller, and a tensioning element and a rotating element on the machine body. The tensioning element is used to adjust the extrusion pressure between the upper pressure roller and the lower support roller, and the rotating element... A component is used to drive the upper pressure roller and the lower support roller to rotate. A cutter is vertically slidably arranged on the top of the machine body. A lifting component is provided on the machine body to drive the cutter to slide vertically. The cutter is located on the side of the upper pressure roller facing away from the feeding bracket. A gate-shaped limiting frame is provided between the cutter and the upper pressure roller. The soft rubber tube slides out in a flat shape between the gate-shaped concave side of the limiting frame and the top of the machine body. The cutter is attached to the side of the limiting frame facing away from the upper pressure roller.

[0006] By adopting the above technical solution, the soft rubber tube unwound from the tray first passes between the upper pressure roller and the lower support roller, and then passes out in a flat shape between the tube limiting frame and the top of the machine body. Then, the tensioning component adjusts the squeezing pressure between the upper pressure roller and the lower support roller, so that the soft rubber tube is flattened and maintains a certain tension. During the rotation of the upper pressure roller and the lower support roller driven by the rotating component, the upper pressure roller and the lower support roller use squeezing pressure to transport the flattened soft rubber tube a certain distance towards the tube limiting frame. Finally, the lifting component drives the cutter to descend. The cutter cuts the soft rubber tube when it is attached to one side of the tube limiting frame. At this time, the cross-section of the soft rubber tube will remain flush, which not only reduces the secondary trimming process in the later stage, but also greatly improves the cutting quality of the soft rubber tube cross-section.

[0007] Optionally, the tensioning element includes supports disposed on the top of the machine body and located at both ends of the upper pressure roller. End blocks are rotatably disposed at both ends of the upper pressure roller. Tensioning grooves are provided on the supports for the end blocks to slide vertically. Pressure blocks are slidably disposed in the tensioning grooves of the supports. A tensioning spring is supported between the bottom of the pressure block and the end blocks. A screw is rotatably disposed on the side of the pressure block facing away from the end blocks. The screw is threadedly connected to the supports. A handle is provided at the top of the screw.

[0008] By adopting the above technical solution, after the soft rubber tube passes between the upper pressure roller and the lower support roller, the worker turns the handle, which drives the screw to rotate in the forward direction. Under the restriction of the tension groove, the screw pushes the pressure block down, the tension spring is continuously compressed, the squeezing force between the end block and the pressure block increases, and the soft rubber tube is squeezed and deformed, thereby reducing the possibility of the soft rubber tube accidentally slipping during the transportation process.

[0009] Optionally, the rotating component includes a driven gear coaxially mounted on the upper pressure roller and a driving gear coaxially mounted on the lower support roller. The driven gear meshes with the driving gear. The machine body is equipped with a drive motor electrically connected to the control system, and the lower support roller is coaxially mounted on the output shaft of the drive motor.

[0010] By adopting the above technical solution, the control system starts the drive motor, and the output shaft of the drive motor drives the lower support roller to rotate synchronously. Under the transmission action of the drive gear and the driven gear, the upper pressure roller and the lower support roller rotate synchronously, so that the soft rubber tube squeezed between the upper pressure roller and the lower support roller can achieve the effect of precise conveying, which is conducive to improving the accuracy of the cutting length of the soft rubber tube.

[0011] Optionally, the lifting component includes an electric cylinder mounted on the machine body and electrically connected to the control system. The machine body is provided with a slide, and the cutter is provided with a blade holder. The blade holder is slidably engaged with the slide, and a guide rod is provided at the bottom of the blade holder. The guide rod is mounted on the piston rod of the electric cylinder.

[0012] By adopting the above technical solution, the control system starts the electric cylinder, the piston rod of the electric cylinder extends, and the piston rod drives the cutter holder to descend through the guide rod. The cutter holder drives the cutter to slide vertically downward a certain distance. During this process, the cutter will cut the soft rubber tube.

[0013] Optionally, the machine body is provided with a pressure bar, the length direction of which is perpendicular to the conveying direction of the soft rubber tube. Two conveying plates are arranged on the pressure bar along its length direction, the length direction of which is parallel to the conveying direction of the soft rubber tube. The soft rubber tube is located between the two conveying plates. An adjusting bolt is threadedly connected to the conveying plate. An oblong hole is provided on the pressure bar along its length direction for the adjusting bolt to pass through.

[0014] By adopting the above technical solution, the soft rubber tube can be initially clamped and positioned during the conveying process, reducing the possibility of the soft rubber tube shifting during the conveying process and helping to improve the flatness of the cross-section formed by cutting the soft rubber tube.

[0015] Optionally, a reversing roller is rotatably mounted on the machine body, the reversing roller is located between the material tray and the pressure bar, and the soft rubber tube is horizontally conveyed after passing around the reversing roller.

[0016] By adopting the above technical solution, the amplitude of twisting of the soft rubber hose during transportation is reduced, which helps to further improve the flatness of the cross-section formed by cutting the soft rubber hose.

[0017] Optionally, both the upper pressure roller and the lower support roller are fitted with hard rubber sleeves.

[0018] By adopting the above technical solution, the rigid rubber sleeve reduces the possibility of slippage in the flexible hose, which is conducive to further improving the accuracy of the cutting length of the flexible hose.

[0019] Optionally, an inclined guide tube is provided on the machine body and next to the cutter. The guide tube is located on the side of the cutter facing away from the upper pressure roller. The guide tube is inclined away from the cutter in a downward direction, and the higher end of the inclined guide tube is close to the cutter.

[0020] By adopting the above technical solution, on the one hand, the guide tube facilitates the rapid discharge of the cut soft rubber tube, and on the other hand, the guide tube partially shields the cutter, reducing the possibility of the cutter accidentally causing danger to the workers.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The soft rubber tube unwound on the tray first passes between the upper pressure roller and the lower support roller, and then passes out in a flat shape between the tube limiting frame and the top of the machine body. Then, the tensioning component adjusts the squeezing pressure between the upper pressure roller and the lower support roller, so that the soft rubber tube is flattened and a certain tension is maintained. During the rotation of the upper pressure roller and the lower support roller driven by the rotating component, the upper pressure roller and the lower support roller use squeezing pressure to transport the flattened soft rubber tube a certain distance towards the tube limiting frame. Finally, the lifting component drives the cutter to descend. The cutter will cut the soft rubber tube when it is attached to one side of the tube limiting frame. At this time, the cross-section of the soft rubber tube will remain flush, which not only reduces the secondary trimming process in the later stage, but also greatly improves the cutting quality of the soft rubber tube cross-section. 2. After the soft rubber hose passes between the upper pressure roller and the lower support roller, the worker turns the handle, which drives the screw to rotate in the forward direction. Under the restriction of the tension groove, the screw pushes the pressure block down, the tension spring is continuously compressed, the squeezing force between the end block and the pressure block increases, and the soft rubber hose is squeezed and deformed, thereby reducing the possibility of the soft rubber hose slipping accidentally during the transportation process. 3. The control system starts the drive motor, and the output shaft of the drive motor drives the lower support roller to rotate synchronously. Under the transmission action of the drive gear and the driven gear, the upper pressure roller and the lower support roller rotate synchronously, so that the soft rubber tube squeezed between the upper pressure roller and the lower support roller can achieve the effect of precise conveying, which is beneficial to improving the accuracy of the cutting length of the soft rubber tube.

[0026] The following is in conjunction with the appendix Figures 1-3This application will be described in further detail.

[0027] This application discloses a flexible hose cutting device.

[0028] Reference Figure 1 A soft rubber tube cutting device includes a body 1, a feeding bracket 2 is bolted to the body 1, a disc shaft 19 is rotatably connected to the feeding bracket 2, a material disc 3 is coaxially sleeved on the disc shaft 19, and a soft rubber tube 4 is wound on the material disc 3.

[0029] Reference Figure 1 A pressure strip 12 is bolted to the top of the machine body 1. The length direction of the pressure strip 12 is perpendicular to the conveying direction of the soft rubber tube 4. Two conveying plates 13 are arranged on the pressure strip 12 along its length direction. The length direction of the conveying plates 13 is parallel to the conveying direction of the soft rubber tube 4. The soft rubber tube 4 is located between the two conveying plates 13.

[0030] Reference Figure 1 The top of the conveyor plate 13 is threaded with an adjusting bolt 14. The pressure bar 12 has a waist-shaped hole 15 along its length for the adjusting bolt 14 to pass through. A reversing roller 16 is rotatably connected to the machine body 1. The reversing roller 16 is located between the material tray 3 and the pressure bar 12. The soft rubber tube 4 passes around the reversing roller 16 and is conveyed horizontally.

[0031] Reference Figure 2 The machine body 1 is rotatably arranged with an upper pressure roller 5 and a lower support roller 6. The upper pressure roller 5 is located directly above the lower support roller 6. Both the upper pressure roller 5 and the lower support roller 6 are fitted with hard rubber sleeves 17, which can be made of hard rubber material. The soft rubber tube 4 passes between the upper pressure roller 5 and the lower support roller 6.

[0032] The worker first adjusts the distance between the two conveyor plates 13 by adjusting bolt 14. Then, the soft rubber tube 4, which is rolled on the material tray 3, is wrapped around the reversing roller 16 and placed between the two conveyor plates 13. Finally, it passes between the upper pressure roller 5 and the lower support roller 6.

[0033] Reference Figure 1 and Figure 2 The machine body 1 is provided with a tensioning element 7, which is used to adjust the extrusion pressure between the upper pressure roller 5 and the lower support roller 6. The tensioning element 7 includes a support 71 bolted to the top of the machine body 1 and located at both ends of the upper pressure roller 5. Both ends of the upper pressure roller 5 are rotatably provided with end blocks 72.

[0034] Reference Figure 2 The support 71 is provided with a tension groove 73 for the end block 72 to slide vertically. A pressure block 74 is vertically slidably arranged in the tension groove 73 of the support 71. A tension spring 75 supports the bottom of the pressure block 74 and the top of the end block 72. A screw 76 is rotatably connected to the side of the pressure block 74 facing away from the end block 72. The screw 76 is threaded onto the support 71. A handle 77 is bolted to the top of the screw 76.

[0035] Reference Figure 2 A rotating component 8 is arranged on the machine body 1. The rotating component 8 is used to drive the upper pressure roller 5 and the lower support roller 6 to rotate. The rotating component 8 includes a driven gear 81 coaxially bolted to the upper pressure roller 5 and a driving gear 82 coaxially bolted to the lower support roller 6. The driven gear 81 meshes with the driving gear 82. A drive motor 83 electrically connected to the control system is bolted to the machine body 1. The lower support roller 6 is coaxially bolted to the output shaft of the drive motor 83.

[0036] The worker turns the handle 77, which drives the screw 76 to rotate in the forward direction. Under the restriction of the tension groove 73, the screw 76 pushes the pressure block 74 down, and the tension spring 75 is continuously compressed. The squeezing force between the end block 72 and the pressure block 74 increases, and the soft rubber tube 4 is squeezed and deformed.

[0037] Reference Figure 1 and Figure 3 A cutter 9 is vertically slidably arranged on the top of the machine body 1. The cutter 9 is located on the side of the upper pressure roller 5 away from the material support 2. A gate-shaped limiting frame 11 is bolted between the cutter 9 and the upper pressure roller 5. The limiting frame 11 is close to the upper pressure roller 5. The soft rubber tube 4 slides out in a flat shape between the gate-shaped concave side of the limiting frame 11 and the top of the machine body 1. The cutter 9 is attached to the side of the limiting frame 11 away from the upper pressure roller 5.

[0038] Reference Figure 3 The machine body 1 is provided with a lifting component 10 that drives the cutter 9 to slide vertically. The lifting component 10 includes an electric cylinder 101 that is bolted inside the machine body 1 and electrically connected to the control system. A slide 102 is bolted to the top of the machine body 1. A cutter holder 103 is bolted to the cutter 9. The cutter holder 103 slides with the slide 102. A vertical guide rod 104 is welded to the bottom of the cutter holder 103. The bottom end of the guide rod 104 passes through the inner and outer walls of the machine body 1 and is bolted to the piston rod of the electric cylinder 101.

[0039] Reference Figure 3 An inclined guide tube 18 is bolted to the machine body 1 next to the cutter 9. The guide tube 18 is located on the side of the cutter 9 facing away from the pressure roller 5. The guide tube 18 is inclined away from the cutter 9 in a downward direction, and the higher end of the inclined guide tube 18 is close to the cutter 9.

[0040] After being squeezed by the upper pressure roller 5 and the lower support roller 6, the soft rubber tube 4 will slide out in a flat shape between the concave side of the tube limiting frame 11 and the top of the machine body 1. At this time, the control system starts the drive motor 83. The output shaft of the drive motor 83 drives the lower support roller 6 to rotate synchronously. Under the transmission action of the drive gear 82 and the driven gear 81, the upper pressure roller 5 and the lower support roller 6 rotate synchronously. The squeezed soft rubber tube 4 is continuously conveyed under the combined action of the upper pressure roller 5 and the lower support roller 6.

[0041] After the flexible tube 4 is conveyed a distance from one end of the tube limiting frame 11 near the cutter 9, the control system starts the electric cylinder 101. The piston rod of the electric cylinder 101 extends downward, and the piston rod of the electric cylinder 101 drives the cutter 9 on the cutter holder 103 to descend synchronously a certain distance through the guide rod 104. During this process, the cutter 9 will cut the flexible tube 4, and the cut flexible tube 4 will be discharged through the guide tube 18.

[0042] The implementation principle of a soft rubber tube cutting device in this application embodiment is as follows: the worker first adjusts the distance between the two conveyor plates 13 by adjusting the bolt 14, then the soft rubber tube 4 rolled on the material tray 3 is passed around the reversing roller 16 and placed between the two conveyor plates 13, and finally passes through the upper pressure roller 5 and the lower support roller 6.

[0043] The worker turns the handle 77, which drives the screw 76 to rotate in the forward direction. Under the restriction of the tension groove 73, the screw 76 pushes the pressure block 74 down, and the tension spring 75 is continuously compressed. The squeezing force between the end block 72 and the pressure block 74 increases, and the soft rubber tube 4 is squeezed and deformed.

[0044] After being squeezed by the upper pressure roller 5 and the lower support roller 6, the soft rubber tube 4 will slide out in a flat shape between the concave side of the tube limiting frame 11 and the top of the machine body 1. At this time, the control system starts the drive motor 83. The output shaft of the drive motor 83 drives the lower support roller 6 to rotate synchronously. Under the transmission action of the drive gear 82 and the driven gear 81, the upper pressure roller 5 and the lower support roller 6 rotate synchronously. The squeezed soft rubber tube 4 is continuously conveyed under the combined action of the upper pressure roller 5 and the lower support roller 6.

[0045] After the flexible tube 4 is conveyed a distance from one end of the tube limiting frame 11 near the cutter 9, the control system starts the electric cylinder 101. The piston rod of the electric cylinder 101 extends downward, and the piston rod of the electric cylinder 101 drives the cutter 9 on the cutter holder 103 to descend synchronously a certain distance through the guide rod 104. During this process, the cutter 9 will cut the flexible tube 4, and the cut flexible tube 4 will be discharged through the guide tube 18.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
