Description

Technical Field

[0001] This invention relates to the field of hose surface stripping technology, specifically to a device for stripping the surface of a smooth hose and its stripping process. Background Technology

[0002] Smooth rubber hoses used in hydraulic and pneumatic pipelines often have a built-in steel wire braided or wound reinforcement layer. Before assembling the pipeline with crimped joints, the outer surface rubber of the hose opening needs to be peeled off to ensure that the joint and the steel wire reinforcement layer fit tightly together and to ensure the pipeline's sealing and pressure resistance performance. Therefore, the peeling of the outer wall of the smooth rubber hose is an essential process in hose processing.

[0003] Existing rubber stripping devices only have a separate stripping blade, which can only cut and peel off the outer surface rubber of the hose. Due to the effects of rubber tearing and cutting, blade scraping, and eccentric cutting of the hose, rubber burrs or stringy residue, as well as small steel wire burrs, are easily generated at the stripped end of the hose after stripping. At the same time, the motor shaft and the loading shaft of traditional rubber stripping equipment are rigidly coaxially fixed, and the installation angle of the stripping blade is locked, which can only achieve vertical coaxial cutting. Vertical cutting resistance is high, and the smooth outer wall of the hose is prone to slippage and deviation. The blade is prone to horizontally hooking the internal steel wire reinforcement layer, causing the steel wire to fraying or burr. Furthermore, it is impossible to adapt the oblique cutting angle according to the hose material, outer rubber thickness, and aging hardness. For soft silicone smooth hoses and aged hard hydraulic hoses, it is impossible to adapt to the optimal cutting angle, which easily leads to rubber residue or over-cutting of the steel wire. Meanwhile, the existing equipment has a separate and independent structure for the peeling blade and deburring component, which requires separate debugging and positioning and separate start-up and shutdown operations. When adapting to different specifications of hoses, double machine adjustment is required. The separate blade layout occupies equipment space. For small and medium-sized processing workshops and outdoor maintenance conditions, it is necessary to purchase two independent machines for peeling and deburring, which results in high equipment investment costs and poor alignment accuracy when changing materials in the pipeline. Therefore, the present invention provides a surface peeling device for smooth hoses and its peeling process. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing the surface of a smooth adhesive tube and its adhesive removal process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for peeling off the surface of a smooth rubber tube and its peeling process, comprising a housing and a shaft core, the shaft core being rotatably mounted on the top side of the housing, peeling blades for peeling off the surface of the rubber tube being symmetrically arranged on both sides of the shaft core, and an adjusting element for adjusting the angle of the peeling blades being provided on the outside of the blades. The adjusting components include; Two slide plates, each with a receiving groove at one end, have two peeling blades rotatably installed in the inner cavities of the two receiving grooves. Rotating shafts, rotatably connected to the inner walls of the receiving grooves, are fixedly installed on the upper and lower sides of the two peeling blades. Tensioning wheels are rotatably installed on the top of the rotating shafts at the top of the peeling blades and on the top of the two slide plates. Adjacent tensioning wheels are rotatably connected by a tensioning belt. Worm gears are fixedly installed on the top of the tensioning wheels rotatably connected to the top of the slide plates. Worms meshing with the worm gears are rotatably installed on the top of the two slide plates. A drive motor for rotating the worm gears is fixedly installed on the top of the two slide plates.

[0006] Both slide plates have protective housings fixedly installed on their tops to protect the tensioning wheel. The peeling blade has a sliding groove at the end away from the tip. A slider is slidably installed in the inner cavity of the sliding groove. A grinding strip for grinding the peeling part of the rubber tube is fixedly installed at the end of the slider that extends outside the sliding groove. Multiple compression springs connected to the inner wall of the sliding groove are fixedly installed at the other end of the slider.

[0007] Both slide plates have sleeves slidably fitted onto their outer walls. A support plate is fixedly installed in the inner cavity of the housing. The support plate is located directly below the two sleeves, and a guide groove is provided on one side of the support plate. A bidirectional threaded rod is rotatably installed in the inner cavity of the guide groove. An output motor for rotating the bidirectional threaded rod is fixedly installed on one side of the housing. Two guide blocks are symmetrically fitted onto the outer wall of the bidirectional threaded rod. A vertical plate perpendicular to itself is fixedly installed at one end of each guide block extending outside the guide groove. A threaded hole adapted to the bidirectional threaded rod is provided on one side of each guide block. A bearing rod is fixedly installed at the end of each vertical plate away from the guide blocks. The end of each bearing rod away from the vertical plate is rotatably connected to the bottom of the two sleeves respectively.

[0008] Both sleeves have a connecting block fixedly installed at their bottom. Each connecting block has a spherical groove at its end away from the sleeve. An adjusting ball is rotatably installed in the inner cavity of each spherical groove. The end of the bearing rod away from the vertical plate is fixedly connected to the outer wall of the adjusting ball.

[0009] Both slide plates have threaded grooves at the ends away from the peeling blades. Adjustable threaded rods are installed in the inner cavities of both threaded grooves through threaded engagement. U-shaped brackets are rotatably sleeved at the ends of the two adjusting threaded rods that extend outside the threaded grooves. One end of the U-shaped bracket is fixedly connected to one end of the sleeve.

[0010] U-shaped lugs are fixedly installed on one side of each of the two sleeves. A vertical rod is rotatably installed in the inner cavity of the U-shaped lugs via a rotating shaft. A cylinder is fixedly installed on one side of each of the two vertical plates. The power output ends of the two cylinders are fixedly connected to the bottom of the vertical rods respectively.

[0011] Support rods are rotatably mounted on the other side of both sleeves. A slide tube is slidably sleeved on the outer wall of the support rod. The bottom of the slide tube is fixedly connected to the outer wall of the vertical plate. A return spring is fixedly sleeved on the outer wall of the support rod. One end of the return spring is fixedly connected to the inner wall of the slide tube.

[0012] A cleaning groove is provided on one side of the housing for cleaning the peeled glossy adhesive, and a cover plate for covering the peeled part of the adhesive tube is installed on the top of the housing via a hinge. A sealing door is installed in the inner cavity of the cleaning groove via a hinge.

[0013] A support base is fixedly installed on one side of the top of the housing. One end of the shaft is rotatably connected to the end of the support base near the opening of the housing. A drive motor for rotating the shaft is fixedly installed on one side of the top of the housing.

[0014] A stripping process for removing adhesive from the surface of a smooth rubber tube includes the following steps: S1. When it is necessary to peel the rubber from the end of the hose, first open the cover plate, put the hose end to be processed into the outside of the shaft, use the shaft to achieve internal support and positioning of the hose, close the cover plate, and then start the output motor according to the outer diameter specification of the hose to drive the bidirectional threaded rod to rotate, adjust the horizontal distance between the two sets of peeling blades, rotate the adjusting threaded rod to fine adjust the longitudinal feed of the blades and control the peeling depth, and then coordinate with the cylinder and adjusting ball to adjust the tilt angle of the peeling blades to match the spiral pattern of the hose wire.

[0015] S2. During the stripping operation, start the drive motor to rotate the hose by driving the shaft. The tip of the stripping blade will contact the outer wall of the hose and peel off the smooth rubber surface of the hose circumferentially. After stripping, stop the shaft rotation. The drive motor will drive the worm gear to mesh with the worm wheel, and with the help of the tension belt, drive the stripping blade to rotate 180° along its own axis, so that the grinding strip faces the stripping cut of the hose. Start the drive motor again to rotate the hose. The compression spring will push the grinding strip to elastically contact the cut, removing the rubber flash and steel wire burrs at the end. After the operation is completed, stop the machine, open the cover plate to remove the processed hose, open the sealing door, and clean the residual rubber debris inside the housing through the cleaning groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up symmetrically arranged self-rotating stripping blades, in conjunction with the worm gear, worm, and tension wheel and tension belt linkage transmission structure, the stripping blades can be precisely driven to rotate 180° along their own axis, quickly completing the switching between the stripping tip and the grinding strip station. It integrates and simultaneously completes two processes: stripping the outer wall of the smooth rubber hose and deburring the stripping port. There is no need to disassemble and replace the blades or transfer them to a separate grinding equipment for secondary processing, which greatly simplifies the processing procedure. At the same time, the grinding strip relies on the compression spring to achieve elastic expansion and contraction, which can adapt to the roundness error of the outer wall of the rubber hose, and the grinding is uniform and thorough. It effectively removes rubber flash, residual rubber, and small steel wire burrs, avoiding the problems of scratching the intact tube wall and damaging the internal steel wires by manual grinding, improving the yield of rubber hose stripping processing. In addition, the worm gear has mechanical self-locking performance, which can lock the rotation angle of the blades and prevent the blades from deviating and shaking during stripping and grinding operations, making the operation more stable.

[0017] 2. The feed depth of the blade can be precisely adjusted by adjusting the threaded rod, and the peeling thickness can be controlled to prevent over-cutting of the steel wire and peeling residue. With the universal rotation of the adjusting ball, combined with the linkage support of the cylinder and the return spring, the peeling blade can be tilted and adjusted at any angle, changing the angle between the blade and the shaft core, realizing oblique progressive peeling, reducing cutting resistance, and cutting along the spiral pattern of the steel wire inside the hose, eliminating the problem of the blade laterally hooking the steel wire and causing fraying. At the same time, it can be adapted to different peeling conditions of hard aging adhesive and soft smooth hose. A single unit can complete processing of multiple working conditions, reducing equipment purchase costs and making it suitable for batch processing in the workshop. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figure 1-7 This embodiment provides a surface peeling device for smooth rubber hoses and its peeling process, including a housing 2 and a shaft 13. The shaft 13 is rotatably mounted on the top side of the housing 2. The housing 2 is an enclosed metal shell structure used to house and protect the bottom transmission and adjustment components, isolate peeling debris from operators, and improve operational safety. Meanwhile, the shaft 13 is made of wear-resistant hard alloy material and is used to fit inside the opening of the smooth rubber hose to provide internal support and positioning for the hose, ensuring the roundness of the hose opening when the hose is rotated for peeling and avoiding eccentric deformation of the hose wall.

[0022] Furthermore, such as Figure 1-2 As shown, a cleaning groove is provided on one side of the housing 2 for cleaning up the debris of the peeled rubber. The peeled rubber outer skin and grinding debris can be discharged through the cleaning groove. The top of the housing 2 is hinged to install a cover plate 1 to cover the rubber tube peeling area. When peeling, the cover plate 1 is closed to prevent debris from splashing. The rubber tube can be disassembled and assembled by opening the cover plate 1. A sealing door 3 is hinged to the inner cavity of the cleaning groove. Under normal conditions, the sealing door 3 is closed to ensure the airtightness of the housing. When cleaning debris, the sealing door 3 can be opened to carry out the operation.

[0023] Furthermore, a support base 4 is fixedly installed on one side of the top of the housing 2. The support base 4 adopts a reinforced support structure to improve the rotational stability of the shaft core 13. One end of the shaft core 13 is rotatably connected to one end of the support base 4 near the opening of the housing 2. A drive motor for rotating the shaft core 13 is fixedly installed on one side of the top of the housing 2. After the drive motor starts, it drives the shaft core 13 to rotate at a constant speed, which in turn drives the smooth rubber tube sleeved outside the shaft core 13 to rotate synchronously. With the help of the peeling blade 20 after the angle is adjusted at rest, the circumferential peeling operation of the outer wall of the rubber tube is completed.

[0024] Furthermore, such as Figure 1-3 As shown, peeling blades 20 for peeling the adhesive from the surface of the hose are symmetrically arranged on both sides of the shaft core 13. The two sets of peeling blades 20 are symmetrically arranged and can simultaneously adhere to the outer wall of the hose to achieve balanced peeling on both sides, reduce the lateral thrust of cutting on one side, and reduce the probability of the hose slipping and deviating. The peeling blades 20 are provided with an adjustment component for adjusting their own angle. The adjustment component can realize the fine adjustment of the tilt angle and axial displacement of the peeling blades 20 as well as the switching of the rotation position, which can adapt to the peeling operation of smooth hoses with different pipe diameters, different outer wall thicknesses, and different soft and hard materials.

[0025] Furthermore, such as Figure 1-5 As shown, the adjusting component includes two sliding plates 16, each with a rectangular receiving groove 28 at one end. Two peeling blades 20 are rotatably installed in the inner cavities of the two receiving grooves 28. The peeling blades 20 can rotate 180° axially by relying on the receiving grooves 28. The upper and lower sides of the two peeling blades 20 are fixedly installed with rotating shafts. The ends of the rotating shafts are rotatably connected to the inner wall of the receiving grooves 28 through bearings, ensuring that the peeling blades 20 rotate smoothly without jamming.

[0026] The top of the peeling blade 20 and the top of the two slide plates 16 are both rotatably equipped with tensioning wheels. Adjacent tensioning wheels are rotatably connected by a tensioning belt, which is a non-slip rubber synchronous belt, ensuring high transmission accuracy and preventing slippage. A worm gear 26 is fixedly installed on the top of the tensioning wheel that is rotatably connected to the top of the slide plate 16. The worm gear 26 is coaxially fixed to the upper end of the tensioning wheel and can rotate synchronously with the tensioning wheel. A worm 27 that meshes with the worm gear 26 is rotatably installed on the top of each of the two slide plates 16. The worm 27 is vertically arranged and can precisely lock the rotation angle of the peeling blade 20 through the self-locking transmission of the worm gear 26 and the worm 27, preventing the blade from deflecting on its own during peeling operations. A drive motor for the rotation of the worm 27 is fixedly installed on the top of each of the two slide plates 16. The output shaft of the drive motor is coaxially fixed to the end of the worm 27, providing power for the blade's rotation.

[0027] Working condition switching principle: During the peeling operation, the tip of the peeling blade 20 faces the outer wall of the rubber tube to complete the peeling of the outer wall rubber. The worm 27 is driven to rotate by the transmission motor, which meshes with the worm wheel 26 and the corresponding tension wheel to rotate. In conjunction with the tension belt, the lower tension wheel is linked, and finally the peeling blade 20 rotates 180° along its own axis to complete the work position switching. The blade's built-in grinding structure is used to connect with the peeling cut, and the end burrs are removed in one integrated manner.

[0028] Specifically, such as Figure 4-6 As shown, protective housings 15 are fixedly installed on the top of both slide plates 16 to protect the tensioning wheel. The protective housings 15 fasten and cover all the tensioning wheel, worm gear 26, and worm 27 components, preventing rubber debris from getting stuck in the transmission meshing position and ensuring transmission stability. At the same time, the peeling blade 20 has a long strip-shaped sliding groove at the end away from the tip. A slider 25 is horizontally slidably installed in the inner cavity of the sliding groove. The slider 25 can elastically extend and retract along the inner cavity of the sliding groove, and the end of the slider 25 extends to the outside of the sliding groove. A grinding strip 24 is fixedly installed for grinding the peeling area of ​​the rubber tube. The grinding strip 24 is made of wear-resistant frosted metal. After rotating 180° with the blade, it fits the peeling cut and grinds away rubber burrs and steel wire burrs. At the other end of the slider 25, multiple compression springs 23 connected to the inner wall of the sliding groove are fixedly installed. Under normal conditions, the compression springs 23 push the slider 25 outward, so that the grinding strip 24 elastically fits the peeling outer wall of the rubber tube, adapts to the slight roundness error of the tube wall, grinds evenly, and does not scratch the intact tube wall.

[0029] Furthermore, such as Figure 1-3 As shown, sleeves 5 are slidably fitted onto the outer walls of both slide plates 16. The slide plates 16 can slide laterally along the inner cavity of the sleeves 5 to achieve fine adjustment of the blades. A support plate 12 is fixedly installed in the inner cavity of the housing 2. The support plate 12 is horizontally fixed and located directly below the two sleeves 5, serving as a bottom bearing guide. A horizontal guide groove is provided on one side of the support plate 12. A bidirectional threaded rod 9 is rotatably installed in the inner cavity of the guide groove through a bearing. The threads at both ends of the bidirectional threaded rod 9 have opposite directions. An output motor for rotating the bidirectional threaded rod 9 is fixedly installed on one side of the housing 2. The output shaft of the output motor is coaxially fixed with the end of the bidirectional threaded rod 9 to provide bidirectional transmission power.

[0030] Furthermore, two guide blocks 18 are symmetrically fitted on the outer wall of the bidirectional threaded rod 9. Each guide block 18 has a threaded hole on one side that matches the bidirectional threaded rod 9. When the bidirectional threaded rod 9 rotates, it can drive the two sets of guide blocks 18 to slide synchronously towards each other and relative to each other along the guide groove. Each of the two guide blocks 18 has a vertical plate 8 fixedly installed at one end extending outside the guide groove. The vertical plate 8 is arranged vertically to serve as a transition support. Each of the two vertical plates 8 has a bearing rod 10 fixedly installed at the end away from the guide block 18. The end of the two bearing rods 10 away from the vertical plate 8 is rotatably connected to the bottom of the two sleeves 5, thereby synchronously driving the two sets of sleeves 5, the slide plate 16, and the peeling blade 20 to move synchronously, adjusting the relative distance between the two sets of blades to adapt to smooth rubber tubes of different outer diameter specifications.

[0031] Specifically, such as Figure 4-5 As shown, a connecting block 21 is fixedly installed at the bottom of each of the two sleeves 5. A spherical groove is opened at the end of each connecting block 21 away from the sleeve 5. An adjusting ball 22 is rotatably installed in the inner cavity of each spherical groove. The adjusting ball 22 can rotate omnidirectionally at any angle inside the spherical groove. The end of the bearing rod 10 away from the vertical plate 8 is fixedly connected to the outer wall of the adjusting ball 22. Relying on the omnidirectional rotation characteristic of the adjusting ball 22, the sleeve 5, the slide plate 16, and the peeling blade 20 can be tilted at multiple angles as a whole, changing the angle between the peeling blade 20 and the axis of the shaft core 13, realizing oblique spiral peeling, reducing cutting resistance, avoiding the blade from laterally hooking the steel wire inside the tube, and preventing the steel wire from fraying and burring.

[0032] Furthermore, a U-shaped ear plate is fixedly installed on one side of each of the two sleeves 5. A vertical rod 11 is rotatably installed in the inner cavity of the U-shaped ear plate via a rotating shaft. The vertical rod 11 can rotate slightly along the U-shaped ear plate. A cylinder is fixedly installed on one side of each of the two vertical plates 8. The power output end of the two cylinders is fixedly connected to the bottom of the vertical rod 11. The extension and retraction of the cylinder can push the vertical rod 11 to swing. The linkage sleeve 5 is omnidirectionally deflected by the bottom adjusting ball 22 to assist in quickly adjusting the blade tilt angle. After the adjustment is completed, the cylinder is locked to fix the blade tilt angle and ensure the stability of the peeling operation.

[0033] Furthermore, support rods 17 are rotatably mounted on the other side of both sleeves 5. A slide tube 7 is slidably sleeved on the outer wall of the support rod 17. The bottom of the slide tube 7 is fixedly connected to the outer wall of the upright plate 8. The slide tube 7 can slide vertically along the outer wall of the support rod 17. A return spring 29 is fixedly sleeved on the outer wall of the support rod 17. One end of the return spring 29 is fixedly connected to the inner wall of the slide tube 7. When the blade tilt angle is adjusted, the support rod 17 slides relative to the slide tube 7, squeezing or stretching the return spring 29. After adjustment, the return spring 29 provides elastic support force to counteract the lateral component force of the peeling and cutting, reduce the rotational load of the adjusting ball 22, and prevent the blade angle from shifting on its own during operation.

[0034] Each of the two slide plates 16 has a threaded groove 19 at the end furthest from the peeling blade 20. An adjusting threaded rod 14 is installed in the inner cavity of each of the two threaded grooves 19 through a threaded fit. Rotating the adjusting threaded rod 14 can drive the slide plate 16 to slide longitudinally along the inner cavity of the sleeve 5 through the threaded transmission. A U-shaped frame 6 is rotatably sleeved at the end of each of the two adjusting threaded rods 14 that extends to the outside of the threaded groove 19. The U-shaped frame 6 plays a limiting and connecting role, and one end of the U-shaped frame 6 is fixedly connected to one end of the sleeve 5, limiting the adjusting threaded rod 14 to only rotate and not move, ensuring that the feed adjustment of the slide plate 16 is precise and controllable, and precisely controlling the depth of the peeling blade 20 cutting into the outer wall of the rubber tube, avoiding overcutting and damage to the internal steel wire and shallow cutting and residual outer glue.

[0035] A stripping process for removing adhesive from the surface of a smooth rubber tube includes the following steps: S1. When it is necessary to peel the rubber from the end of the hose, first open the cover plate 1, put the hose end to be processed into the outside of the shaft core 13, use the shaft core 13 to achieve internal support and positioning of the hose, close the cover plate 1, and then start the output motor according to the outer diameter specification of the hose to drive the bidirectional threaded rod 9 to rotate, adjust the horizontal distance between the two sets of peeling blades 20, rotate the adjusting threaded rod 14 to fine-tune the longitudinal feed of the blades and control the peeling depth, and then coordinate with the cylinder and adjusting ball 22 to adjust the tilt angle of the peeling blades 20 to match the spiral pattern of the hose wire.

[0036] S2. During the stripping operation, start the drive motor to drive the shaft 13 to rotate the rubber tube. The tip of the stripping blade 20 is in contact with the outer wall of the rubber tube, and the smooth rubber on the surface of the rubber tube is peeled off circumferentially. After the stripping is completed, stop the rotation of the shaft 13. The transmission motor drives the worm 27 to mesh with the worm wheel 26. With the help of the tension belt, the stripping blade 20 rotates 180° along its own axis, so that the grinding strip 24 faces the stripping cut of the rubber tube. Start the drive motor again to drive the rubber tube to rotate. The compression spring 23 pushes the grinding strip 24 to elastically fit the cut, removing the rubber flash and steel wire burrs at the end. After the operation is completed, stop the machine, open the cover plate 1 to remove the processed rubber tube, open the sealing door 3, and clean the residual rubber debris in the shell through the cleaning groove.
