Description

Technical Field

[0001] This utility model relates to the field of razor manufacturing technology, specifically to razor blade grinding equipment. Background Technology

[0002] Razor manufacturing refers to the process of transforming raw materials into personal care products (razors) with shaving functions through a series of industrial manufacturing processes. This process covers the entire industrial chain, from product design, raw material procurement, parts processing, assembly to quality inspection, packaging, and final sales.

[0003] When sharpening the blades of a razor, a lathe-grinding device is usually used. This device mounts the sharpening wheel onto a rotating shaft and secures it with a flange. The rotating shaft drives the sharpening wheel to rotate, thus sharpening the blades. When the sharpening wheel needs to be replaced, the rotating shaft must first be disassembled, then the flange used for fixing it must be removed, and only then can the old sharpening wheel be removed for replacement. The whole process is quite cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a razor blade grinding machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a razor blade grinding machine, including a workbench, a recycling frame fixedly installed on the upper surface of the workbench, a base fixedly installed in the central area of ​​the bottom wall of the recycling frame, two support frames connected to the upper surface of the base by an adjustment mechanism, a cooling component between the two support frames, the recycling frame being used to recycle refrigerant, and a guide frame installed in the central area of ​​the upper surface of the base.

[0006] The upper surfaces of the two support frames are rotatably connected to rotating columns on both sides along their length via bearing seats, and the two support frames are connected to the corresponding rotating columns via transmission mechanisms. Each pair of rotating columns is connected to the corresponding support frame via a replacement structure.

[0007] The replacement structure includes two rotating columns with corresponding fixed mounting parts at one end. The two mounting parts are connected by a locking assembly to a bearing cylinder. One end of the bearing cylinder along its axial direction is hinged to the corresponding mounting part. A set of annular grinding rollers are slidably sleeved on the circumferential surface of the bearing cylinder, which are used for coarse grinding and fine grinding respectively. The inner walls of the two grinding rollers are respectively provided with a set of circumferentially distributed slots. A sleeve is fixedly connected to the inner wall of the bearing cylinder. Two sets of sliding grooves are provided between the circumferential surface of the sleeve and the bearing cylinder. Each sliding groove corresponds to the position of the adjacent slot. A locking block is slidably connected inside each sliding groove. Each locking block is slidably inserted into the corresponding slot. A drive assembly for pushing the locking block is provided inside the sleeve.

[0008] Furthermore, each of the aforementioned blocks has a cross-shaped structure, and a set of C-shaped spring steel sheets are fixedly connected to the upper surface of each block. The other end of each spring steel sheet is fixedly connected to the inner wall of the bearing cylinder.

[0009] With the above solution, when the grinding roller needs to be contacted for limiting, the spring steel sheet can push the locking block out of the slot through the deformation force of the spring steel sheet, thereby releasing the locking of the grinding roller.

[0010] Furthermore, the drive assembly includes a rotating rod rotatably connected to the inner wall of the sleeve. Threaded grooves are respectively opened at both ends of the rotating rod along its axial direction. The two threaded grooves are symmetrically arranged. Two symmetrically arranged sliders are slidably connected inside the sleeve. The two sliders are threadedly connected to the corresponding threaded grooves and respectively contact the corresponding multiple locking blocks.

[0011] One end of the rotating rod extends into a sleeve, and a worm gear is fixedly installed at the end of the sleeve. A worm is rotatably connected to one end of the sleeve along its axis through a bearing seat. The worm meshes with the worm gear, and a handle is provided at one end of the worm.

[0012] The above scheme achieves the driving of the locking block through worm gear transmission and the cooperation of the threaded groove and the slider. The operator only needs to turn the handle to control the movement of the locking block through the slider.

[0013] Furthermore, both sliders are tapered, and the end of each block located inside the sleeve is beveled.

[0014] With the above solution, the tapered slider can better cooperate with the beveled block, and the block can be pushed more smoothly when the slider moves.

[0015] Furthermore, a limiting groove is formed on the inner wall of the sleeve, and a convex structure is formed on the circumferential surface of both sliders, which is slidably connected to the limiting groove.

[0016] The above scheme allows the combination of the limiting groove and the protruding structure to guide and limit the movement of the slider.

[0017] Furthermore, the locking assembly includes a fixed cylinder that is slidably sleeved on the circumferential surfaces of two mounting members. The circumferential surfaces of the two mounting members are respectively formed with multiple protrusions. The two fixed cylinders are slidably connected to the corresponding multiple protrusions. One end of each of the two fixed cylinders is fixedly connected to the circumferential surface of the bearing cylinder by bolts.

[0018] The above scheme enables the locking and unlocking of the bearing cylinder through the sliding connection between the fixed cylinder and the protrusion and the fixing with bolts. When the fixed cylinder is fixed, the two mounting parts can rotate synchronously with the bearing cylinder.

[0019] Furthermore, the adjustment mechanism includes a set of slide rails fixedly connected to the upper surface of the base. Both slide rails are triangular in structure. The bottom of the support frame is slidably connected to the slide rails. A cylinder is fixedly installed on the upper surface of the base, and the output end of the cylinder is fixedly connected to the support frame.

[0020] With the above scheme, the cylinder, as a power source, can control the movement distance of the support frame, thereby realizing flexible adjustment of the distance between the two support frames, and thus adjusting the distance between the grinding roller and the guide frame.

[0021] Furthermore, the transmission mechanism includes a drive motor fixedly mounted on the upper surface of the support frame, and pulleys are fixedly mounted on the output end of the drive motor and one end of the adjacent rotating column, and the two pulleys are connected by a transmission belt.

[0022] A protective frame is fixedly installed on the upper surface of the support frame, and the transmission belt and two pulleys are located inside the protective frame.

[0023] The above solution provides a simple and smooth transmission method using pulleys and drive belts; the protective frame protects the transmission components and prevents external debris from affecting the transmission effect.

[0024] Furthermore, the cooling assembly includes two splash guards fixedly installed on the upper surfaces of the support frames, with drain pipes fixedly installed on the inner walls of the two splash guards, and a set of nozzles fixedly connected to each of the two drain pipes along their axial direction. A three-way flexible hose is fixedly connected between the two drain pipes, with the inlet end of the three-way flexible hose fixedly connected to the output end of an external pump body, and a return pipe fixedly connected to one side of the recovery frame.

[0025] The above solution prevents coolant from splashing onto the outside of the equipment, while the combination of drain pipe and nozzle sprays refrigerant onto the processing area to cool it down.

[0026] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0027] This razor blade sharpening machine, through the cooperation of a sleeve, a locking block, a slot, and a sharpening roller, allows the locking block to be inserted into the slot with the assistance of a drive component, thereby limiting the sharpening roller and fixing it onto the carrier cylinder. This is convenient and quick. One end of the carrier cylinder is hinged to the mounting component, allowing the carrier cylinder to be rotated by removing the locking component. The sharpening roller can then be removed and replaced without disassembling the carrier cylinder, thus improving the efficiency of sharpening roller replacement. Attached Figure Description

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Please see Figures 1-10 The razor blade grinding machine in this embodiment includes a workbench 1. A recycling frame 2 is fixedly installed on the upper surface of the workbench 1. A base 3 is fixedly installed in the central area of ​​the bottom wall of the recycling frame 2. Two support frames 5 are connected to the upper surface of the base 3 through an adjustment mechanism 4. A cooling component 6 is arranged between the two support frames 5. The recycling frame 2 is used to recycle refrigerant. A guide frame 7 is installed in the central area of ​​the upper surface of the base 3.

[0053] The upper surfaces of the two support frames 5 are rotatably connected to the rotating columns 8 on both sides along their length direction via bearing seats. The two support frames 5 are respectively connected to the corresponding rotating columns 8 via transmission mechanisms 9. Each pair of rotating columns 8 is connected to the corresponding support frame 5 via a replacement structure 10.

[0054] The replacement structure 10 includes two rotating columns 8 with corresponding mounting parts 1001 fixedly connected at one end. A bearing cylinder 1003 is connected between the two mounting parts 1001 via a locking assembly 1002. One end of the bearing cylinder 1003 along its axial direction is hinged to the corresponding mounting part 1001. A set of annular grinding rollers 1004 is slidably sleeved on the circumferential surface of the bearing cylinder 1003. Each set of grinding rollers 1004 consists of two rollers, used for coarse grinding and fine grinding respectively. The inner walls of the two grinding rollers 1004 each have a set of annular... The sleeve 1006 is fixedly connected to the inner wall of the bearing cylinder 1003, with circumferentially distributed slots 1005. Two sets of sliding grooves 1007 are formed between the circumferential surface of the sleeve 1006 and the bearing cylinder 1003. Each sliding groove 1007 corresponds to the position of an adjacent slot 1005. A locking block 1008 is slidably connected inside each sliding groove 1007, and each locking block 1008 is slidably inserted into its corresponding slot 1005. A drive assembly 1009 for pushing the locking blocks 1008 is provided inside the sleeve 1006. The sleeve 1006, the locking block 1008, the slot 1005, and the grinding roller 1004, in cooperation with the drive assembly 1009, allow the locking block 1008 to be inserted into the slot 1005, thereby limiting the grinding roller 1004 and fixing it to the support cylinder 1003. One end of the support cylinder 1003 is hinged to the mounting part 1001, allowing the support cylinder 1003 to rotate by removing the locking assembly 1002. This allows the grinding roller 1004 to be fixed to the support cylinder 1003 without disassembling it. The grinding roller 1004 is removed and replaced, which improves the efficiency of replacing the grinding roller 1004. Each locking block 1008 has a cross-shaped structure, and a set of C-shaped spring steel plates 11 are fixedly connected to the upper surface of each locking block 1008. The other end of each spring steel plate 11 is fixedly connected to the inner wall of the bearing cylinder 1003. When it is necessary to contact the limiting of the grinding roller 1004, the spring steel plate 11 can push the locking block 1008 out of the slot 1005 through the deformation force of the spring steel plate 11, thereby releasing the locking of the grinding roller.

[0055] The drive assembly 1009 includes a rotating rod 10091 rotatably connected to the inner wall of a sleeve 1006. Threaded grooves 10092 are respectively formed at both ends of the rotating rod 10091 along its axial direction, and the two threaded grooves 10092 are symmetrically arranged. Two symmetrically arranged sliders 10093 are slidably connected inside the sleeve 1006. The two sliders 10093 are threadedly connected to their respective threaded grooves 10092 and respectively contact a plurality of corresponding locking blocks 1008. One end of the rotating rod 10091 extends out of the sleeve 1006, and a worm gear 10094 is fixedly installed at the end extending out of the sleeve 1006. A worm 10095 is rotatably connected to one end of the sleeve 1006 along its axial direction via a bearing seat. The worm 10095 meshes with the worm gear 10094, and one end of the worm 10095 is equipped with… The handle, through the transmission of worm gear 10094 and worm 10095 and the cooperation of threaded groove 10092 and slider 10093, drives the locking block 1008. The operator only needs to turn the handle to control the movement of the locking block 1008 through the slider 10093. Both sliders 10093 are conical in shape, and one end of each locking block 1008 inside the sleeve 1006 is beveled. The conical structure of the slider 10093 can better cooperate with the beveled locking block 1008, and can push the locking block 1008 to move more smoothly when the slider 10093 moves. The inner wall of the sleeve 1006 is provided with a limiting groove, and the circumferential surface of both sliders 10093 forms a convex structure, which is slidably connected with the limiting groove. The cooperation of the limiting groove and the convex structure can guide and limit the movement of the slider 10093.

[0056] The locking assembly 1002 includes a fixed cylinder 10021 that is slidably sleeved on the circumferential surfaces of two mounting members 1001. The circumferential surfaces of the two mounting members 1001 are respectively formed with a plurality of protrusions 10022. The two fixed cylinders 10021 are slidably connected to the corresponding plurality of protrusions 10022. One end of the two fixed cylinders 10021 is respectively fixedly connected to the circumferential surface of the bearing cylinder 1003 by bolts. Through the sliding connection between the fixed cylinders 10021 and the protrusions 10022 and the fixing of the bolts, the bearing cylinder 1003 can be locked and unlocked. When the fixed cylinder 10021 is fixed, the two mounting members 1001 can rotate synchronously with the bearing cylinder 1003.

[0057] The adjustment mechanism 4 includes a set of slide rails 401 fixedly connected to the upper surface of the base 3. Both slide rails 401 are triangular in structure. The bottom of the support frame 5 is slidably connected to the slide rails 401. A cylinder 402 is fixedly installed on the upper surface of the base 3. The output end of the cylinder 402 is fixedly connected to the support frame 5. The cylinder 402 serves as a power source and can control the movement distance of the support frame 5, thereby realizing flexible adjustment of the distance between the two support frames 5, and thus adjusting the gap between the grinding roller 1004 and the guide frame 7.

[0058] The transmission mechanism 9 includes a drive motor 901 fixedly mounted on the upper surface of the support frame 5. The output end of the drive motor 901 and one end of the adjacent rotating column 8 are both fixedly mounted with pulleys 902. The two pulleys 902 are connected by a transmission belt. A protective frame 903 is fixedly mounted on the upper surface of the support frame 5. The transmission belt and the two pulleys 902 are all located inside the protective frame 903. The transmission method of the pulleys 902 and the transmission belt is simple in structure and smooth in transmission. The protective frame 903 can protect the transmission components and prevent external debris from entering and affecting the transmission effect.

[0059] The cooling assembly 6 includes two support frames 5 with splash guards 601 fixedly installed on their upper surfaces. Drain pipes 602 are fixedly installed on the inner walls of the two splash guards 601. A set of nozzles 603 are fixedly connected to each of the two drain pipes 602 along their axial direction. A three-way hose 604 is fixedly connected between the two drain pipes 602. The inlet end of the three-way hose 604 is fixedly connected to the output end of an external pump. A return pipe 605 is fixedly connected to one side of the recovery frame 2. The splash guards 601 can prevent coolant from splashing to the outside of the equipment. The combination of the drain pipes 602 and the nozzles 603 can spray refrigerant onto the processing area to achieve cooling of the processing area.

[0060] The working principle of the above embodiment is as follows: when the blade steel strip is being ground, the blade steel strip is conveyed to the guide frame 7 through the external conveying equipment, and then passed through the guide frame 7 and wound up to the external winding equipment.

[0061] Subsequently, the two cylinders 402 push the corresponding support frame 5 to slide on the corresponding slide rail 401, thereby adjusting the distance between the grinding roller 1004 and the guide frame 7, so that the two grinding rollers 1004 can contact the blade strip during the grinding process. Then, the two drive motors 901 drive and drive the corresponding rotating column 8 to rotate through the corresponding transmission belt, so that the rotating column 8 drives the corresponding bearing cylinder 1003 to rotate synchronously through the connecting piece and the fixed cylinder 10021, so that the bearing cylinder 1003 can perform grinding work with the blade strip through the two grinding rollers 1004 during the rotation.

[0062] During the polishing process, an external pump can deliver refrigerant to two drain pipes 602 through a three-way hose 604, and discharge it into the polishing area through multiple nozzles 603 to achieve cooling of the polishing area.

[0063] When the grinding roller 1004 on the surface of the bearing cylinder 1003 needs to be replaced, the cylinder 402 pushes the support frame 5 away from the guide frame 7. Then, the bolts on one of the fixed cylinders 10021 are removed, and the fixed cylinder 10021 is slid to separate it from the bearing cylinder 1003. The bearing cylinder 1003 is rotated at the hinge between the bearing cylinder 1003 and the other mounting piece 1001. Then, the worm gear 10095 is rotated by the handle, causing the worm gear 10095 to mesh with the worm wheel 10094, thereby driving the rotating rod 10091 to rotate. During rotation, the two threaded grooves 10092 on the slide can drive the two sliders 10093 to move closer to each other. When the two sliders 10093 slide into place, they will separate from the corresponding locking block 1008. Then, the deformation force of the spring steel sheet 11 can push the corresponding locking block 1008 to reset, so that the locking block 1008 separates from the locking groove 1005. Then, the operator can remove the grinding roller 1004 sleeved on the surface of the bearing cylinder 1003 and replace the grinding roller 1004. In this process, it is not necessary to completely disassemble the bearing cylinder 1003, which is more convenient.

[0064] During the installation phase, after the grinding roller 1004 is fitted onto the support cylinder 1003, the slot 1005 on the grinding roller 1004 is aligned with the sliding groove 1007 on the support cylinder 1003. Then, the screw is rotated in the opposite direction to move the two sliders 10093 away from each other and push the corresponding locking block 1008 to slide in the sliding groove 1007 and enter the slot 1005 to fix the grinding roller 1004. Then, the support cylinder 1003 is rotated to align with the mounting part 1001, and the fixing cylinder 10021 on the mounting part 1001 is slid onto the support cylinder 1003. Finally, the fixing cylinder 10021 is fixed onto the support cylinder 1003 with bolts.
