TECHNICAL FIELD
[0001] The present application relates to the technical field of shavers, in particular to a shaver blade marking device. BACKGROUND
[0002] A razor is a knife used for shaving or trimming the beard or hair. It is primarily used by men to shave facial hair, but is also used by women to shave legs and underarms. The blade is sharpened by rubbing it on rawhide. There are two types of razors, one is used for personal hygiene, and the other is used for mechanical processing and manufacturing. The latter is composed of a blade and a spade-shaped holder made of aluminum, stainless steel, copper or plastic. The blade is made of stainless steel or carbon steel and is coated with metal or chemicals to make it sharp and durable.
[0003] Patent application number CN202323135474.0 includes a support, a marking table, a limiting plate, a longitudinal slide rail, a bearing plate, a first slide block, a second cylinder, a transverse slide rail, a sliding plate, a laser marking machine, a second slide block, a second connecting rod, a connecting vertical plate, a connecting horizontal plate, a first cylinder and a first connecting rod. The marking table is arranged on the surface of the bottom of the support, the limiting plate is arranged on the surface of the marking table, the longitudinal slide rail is arranged on the upper surface of the support, the bearing plate is arranged on the upper part of the longitudinal slide rail, and the bearing plate is connected with the longitudinal slide rail through the first slide block, and the second cylinder is arranged on the front part of the bearing plate. The razor blades to be marked are arranged on the surface of the marking table in sequence, and are limited by the limiting plate. The laser marking machine marks the blades on the surface of the marking table in sequence. However, such a marking device needs to place a piece of blade on the surface of the marking table, which is low in efficiency by manual placement, and the marking machine needs to move horizontally and vertically for each blade marking, which further limits the marking efficiency of the blade.
[0004] The present application is proposed to overcome the shortcomings of the prior art. SUMMARY
[0005] The present application aims to overcome the shortcomings of the prior art and provides a shaver blade marking device.
[0006] The present application can be realized by the following technical solutions: This invention discloses a razor blade marking device, comprising a frame, a support plate fixed on the frame, a laser marking head fixed on the frame above the support plate, a feeding shaft rotatably connected to the frame on one side of the support plate, a feeding roll fixed on the feeding shaft, and a take-up shaft rotatably connected to the frame on the other side of the support plate, a take-up roll fixed on the take-up shaft, the take-up shaft being driven to rotate by a take-up motor. A conveying device is also provided on the frame below the support plate, the conveying device comprising a support rod fixed to the frame, and a support rod through-hole on the support rod. A support tube is slidably connected to a support rod. A support shaft is vertically fixed on the support tube. A positioning block is provided on the support shaft, through which the support shaft passes and slidably connected. A conveying plate is fixed on the positioning block. A conveying block is fixed on the conveying plate. A rotating block is provided on the positioning block and rotatably connected to it. A rotating rod is fixed on the rotating block. A slider is provided on the rotating rod and slidably connected to it. A spring is also fixed between the slider and the rotating block. A conveying rod is also provided on the frame and rotatably connected to it. The end of the conveying rod is fixed to the slider. The conveying rod is driven to rotate by a conveying motor. Preferably, a take-up roller is fixed on the take-up shaft, and a friction roller that contacts the take-up roller is fixed at the output end of the take-up motor. After the blade strip is marked with blades for a period of time, the blade strip at the take-up position becomes loose. The friction roller is driven to rotate by the take-up motor, and the friction between the friction roller and the take-up roller drives the take-up roller to rotate, thereby achieving the take-up of the blade strip. This avoids the situation where the diameter of the blade roll gradually increases after the blade strip is rewound, which would make it impossible to accurately control the rotation of the take-up shaft.
[0007] Preferably, guide shafts are fixed on both sides of the frame of the support plate, and guide rollers are provided on each guide shaft for rolling connection. The guide rollers guide the blade belt, preventing the blade belt from bending excessively and breaking.
[0008] Preferably, a limiting plate is fixed above each of the support plates. The limiting plate blocks the movement of the blade belt, ensuring its smooth movement.
[0009] Preferably, a limiting block is also fixed on the support shaft. The limiting block prevents the positioning block from separating from the support shaft.
[0010] Preferably, a conveyor motor is fixed on the frame, a conveyor shaft is fixed to the output end of the conveyor motor, a main gear is fixed on the conveyor shaft, and a driven gear is fixed on the conveyor rod, with the driven gear meshing with the main gear. By meshing the main gear and the driven gear, and by setting a relatively large gear ratio, the conveyor motor can precisely drive the conveyor rod to rotate.
[0011] Preferably, limit shafts are fixed on both sides of the frame above the conveyor plate, and each limit shaft is equipped with a limit roller rotatably connected to the limit shaft. The limit rollers press the blade belt down from the top of the blade belt, keeping the blade belt on the support plate, preventing the blade belt at the conveyor position from bulging, and ensuring that the conveyor block is accurately inserted into the positioning hole of the blade.
[0012] Compared with existing technologies, the present invention has the following advantages: This device uses a moving conveyor plate to insert the conveyor block into the positioning hole of the blade, which in turn moves the blade belt. This allows the blades to be moved one by one under the laser marking head, where they are laser-marked. This eliminates the need for manual placement and collection of the marked blades, and also eliminates the need to move the laser marking head, greatly improving the marking efficiency of the blades.

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example
[0015] like Figures 1 to 3As shown, this embodiment discloses a razor blade marking device, including a frame 1, a support plate 9 fixed on the frame 1, a laser marking head 11 fixed on the frame 1 above the support plate 9, a feeding shaft 2 rotatably connected to the frame 1 on one side of the support plate 9, a feeding roll 3 fixed on the feeding shaft 2, a take-up shaft 4 rotatably connected to the frame 1 on the other side of the support plate 9, a take-up roll 5 fixed on the take-up shaft 4, and the take-up shaft 4 is driven to rotate by a take-up motor 7. A conveying device 14 is also provided on the frame 1 below the support plate 9, the conveying device 14 including a support rod 15 fixed on the frame 1, and a support rod 15 having a through-hole and sliding mechanism. A support tube 16 is connected, and a support shaft 17 is vertically fixed on the support tube 16. A positioning block 19 is provided on the support shaft 17, through which the support shaft 17 passes and is slidably connected to the support shaft 17. A conveying plate 20 is fixed on the positioning block 19, and a conveying block 21 is fixed on the conveying plate 20. A rotating block 22 is provided on the positioning block 19 and is rotatably connected to the positioning block 19. A rotating rod 23 is fixed on the rotating block 22, and a slider 24 is provided on the rotating rod 23 and is slidably connected to the rotating rod 23. A spring 30 is also fixed between the slider 24 and the rotating block 22. A conveying rod 25 is also provided on the frame 1 and is rotatably connected to the frame 1. The end of the conveying rod 25 is fixed to the slider 24, and the conveying rod 25 is driven to rotate by a conveying motor 26.Blades are typically manufactured in the form of blade strips. Positioning holes for each blade are punched into the blade strip, and cutting edges are ground on both sides. The ground blade strip is then wound onto a feed roll 3, which is bolted to a feed shaft 2. A blank take-up roll 5 is fixed to a take-up shaft 4. After the blade strip passes through the conveyor 14, its end is fixed to the take-up roll 5. The conveyor 14 drives the blade strip to move, moving the strip by the length of one blade at a time. When each blade passes the laser marking head 11, the laser, through its pump source, excites the working medium, causing population inversion. This inversion oscillates and amplifies in the resonant cavity, producing continuous... The laser beam, passing through the laser marking head 11, acts on the blade, vaporizing the material on the blade surface and forming corresponding marks, thus achieving marking operations on each blade. The conveying device 14 drives the blade movement by rotating the conveying rod 25 via the conveying motor 26. When the conveying rod 25 rotates, the slider 24 rotates with the conveying rod 25, the rotating rod 23 rotates with the slider 24, and the rotating block 22 rotates around the slider 24. Since a spring 30 is fixed between the slider 24 and the rotating block 22, when the rotating rod 23 rotates to a certain angle, the spring 30 pushes the rotating block 22 to move. The rotating block 22 drives the positioning block 19 to move, and the positioning block 19 presses against the support tube 16. As the conveyor plate 20 moves, the conveyor block 21 on the conveyor plate 20 is inserted into the positioning hole of the blade. Then, the conveyor motor 26 drives the conveyor rod 25 to rotate at a certain angle and stops. The position on the blade strip to be marked reaches below the laser marking head 11. Laser marking is then performed on the blade strip through the laser marking head 11. After marking is completed, the conveyor motor 26 drives the conveyor rod 25 to continue rotating. After the blade strip continues to move forward a certain distance, when the rotating rod 23 rotates to a downward tilt, the positioning block 19 descends. The positioning block 19 drives the conveyor plate 20 to descend. After the conveyor block 21 separates from the positioning hole on the blade strip, the conveyor rod 25 continues to rotate. When the conveyor rod 25 rotates to an upward tilt again, the spring 30... The positioning block 19 is pushed against the support tube 16 again. As the positioning block 19 rises, the conveyor block 21 is inserted into the positioning hole of the next blade and moves the blade belt a certain distance before the conveyor motor 26 stops. The marking position of the next blade on the blade belt reaches below the laser marking head 11. This cycle continues, and while marking the blades, the winding motor 7 drives the winding shaft 4 to rotate, winding the loose blade belt onto the take-up roll 5. This device uses the movement of the conveyor plate 20 to insert the conveyor block 21 into the positioning hole of the blade and move the blade belt, thus moving the blades one by one to below the laser marking head 11 for laser marking. The take-up shaft 4 is fixed with a take-up roller 6, and the output end of the take-up motor 7 is fixed with a friction roller 8 that contacts the take-up roller 6. After the blade strip is marked with blades for a period of time, the blade strip at the take-up roll 5 becomes loose. The take-up motor 7 drives the friction roller 8 to rotate, and the friction between the friction roller 8 and the take-up roller 6 drives the take-up roller 6 to rotate, thereby achieving the take-up of the blade strip. This avoids the situation where the diameter of the blade roll gradually increases after the blade strip is taken up, which would make it impossible to accurately control the rotation of the take-up shaft 4.
[0016] Guide shafts 12 are fixed on both sides of the frame 1 of the support plate 9, and guide rollers 13 are rolledly connected to the guide shafts 12. The guide rollers 13 guide the blade belt to prevent the blade belt from bending too much and breaking.
[0017] A limit block 18 is also fixed on the support shaft 17. The limit block 18 is used to prevent the positioning block 19 from separating from the support shaft 17.
[0018] The frame 1 is equipped with a conveyor motor 26, and a conveyor shaft 27 is fixed to the output end of the conveyor motor 26. A main gear 28 is fixed to the conveyor shaft 27, and a driven gear 29 is fixed to the conveyor rod 25. The driven gear 29 meshes with the main gear 28. By meshing the main gear 28 with the driven gear 29 and setting a large gear ratio, the conveyor motor 26 can accurately drive the conveyor rod 25 to rotate. Example
[0019] This embodiment discloses a razor blade marking device. Based on the structure and principle of Embodiment 1, this embodiment fixes a limiting shaft 31 on both sides of the frame 1 above the conveyor plate 20. Each limiting shaft 31 is equipped with a limiting roller 32 that is rotatably connected to the limiting shaft 31. The limiting roller 32 presses the blade belt down from the upper end of the blade belt, keeping the blade belt on the support plate 9, preventing the blade belt at the position of the conveyor device 14 from bulging, and achieving accurate insertion of the conveyor block 21 into the positioning hole of the blade. Example
