Description

Technical Field

[0001] This invention relates to the field of polishing technology, and more particularly to a wheel dressing mechanism. Background Technology

[0002] In the razor blade (shaver blade) production process, a grinding machine is used to grind and polish the formed blade edges to ensure their sharpness. To ensure production efficiency, existing factories use wheel sets, where the outer surface of the wheel grinds and polishes the blade edges conveyed at high speed. However, as grinding and polishing progresses, the outer surface of the wheel wears down, and the wear on the wheel sets varies. To avoid the wear on the outer surface affecting the polishing effect, the outer surface of the wheel needs to be ground periodically based on the amount of wear over the grinding and polishing time. Currently, each wheel is manually ground using sandpaper, but manual grinding has the following problems: 1. Uneven grinding force, resulting in uneven outer surface of individual wheel sets; 2. Difficulty in maintaining consistent grinding amount each time, leading to inconsistent sizes of each wheel in the same set; 3. Frequent machine stops are required to disassemble and reassemble the wheel, resulting in reduced blade production. Summary of the Invention

[0009] Optionally, the second connecting member is configured as a spring telescopic rod with the telescopic end facing downward; the second tension roller is fixed to the telescopic end of the second connecting member.

[0010] Optionally, the left side of the front side and the left side of the rear side of the second fixing plate are provided with sliding grooves for the first connecting member to slide; each of the two first connecting members on the left is provided with a sliding block, and the sliding block is located in the corresponding sliding groove; a spring is fixedly connected in the sliding groove, and the other end of the spring is fixedly connected to the sliding block of the first connecting member located in the sliding groove; the spring constant and deformation are both smaller than the spring constant and deformation of the second connecting member.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention assembles a grinding mechanism onto a blade grinding carriage, sets the grinding amount of the grinding mechanism on the leather wheel based on the wear amount of the outer surface of the leather wheel during the blade grinding and polishing time, and then controls the horizontal movement of the grinding plate to perform quantitative grinding on the leather wheel. This achieves grinding operation on the leather wheel without stopping the machine to disassemble it, avoiding frequent machine stops of the blade grinding carriage and frequent disassembly and assembly of the leather wheel, which reduces the output of blades. It also ensures that the grinding amount on the outer surface of all leather wheels is consistent, ensures the uniformity of the outer surface of a single leather wheel, and ensures the subsequent grinding and polishing quality of the blades.

[0016] 2. By setting both the left and right ends of the bottom surface of the grinding plate as upward-sloping surfaces, the side of the grinding plate in the direction of travel is avoided to prevent interference with the wheel.

[0017] 3. By setting the length of the grinding plate to be greater than the distance between four adjacent grinding wheels on the blade grinding carriage, during the grinding process, as the grinding plate moves laterally, the subsequent grinding surface of the grinding plate can be used to grind the outer surface of the grinding wheel that has already been ground in front, ensuring grinding quality and eliminating the need for the grinding plate to stay on the outer surface of the grinding wheel for a period of time, thus improving grinding efficiency.

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0028] Example 1: As Figures 1-4 As shown, a wheel dressing mechanism includes a blade grinding car 1; the blade grinding car 1 is provided with a plurality of wheel 2;

[0029] It also includes a first fixed frame 101, a first slide rail 102, a first electric slider 103, a first fixed plate 104, a second slide rail 201, a second electric slider 202, a second fixed frame 203, a connecting seat 204, and a grinding plate 205; the first fixed frame 101 is detachably connected to the blade grinding wheel 1; the first fixed frame 101 is provided with two symmetrically distributed first slide rails 102; the first slide rail 102 is provided with a first electric slider 103; the first electric slider 103 is fixedly connected to a first fixed plate 104; the first fixed plate 104 is fixedly connected to a second slide rail 201; the second slide rail 201 is provided with a second electric slider 202; the second electric slider 202 is fixedly connected to a second fixed frame 203; the second fixed frame 203 is connected to a connecting seat 204; the connecting seat 204 is connected to a grinding plate 205; the grinding plate 205 is directly opposite the leather wheel 2.

[0030] Furthermore, the connecting seat 204 is detachably connected to the second fixing frame 203; the grinding plate 205 is detachably connected to the connecting seat 204, which facilitates the replacement of the grinding plate 205 for grinding work and ensures the grinding quality of the outer surface of the leather wheel 2.

[0031] Furthermore, the bottom left and bottom right ends of the grinding plate 205 are both upward-sloping surfaces.

[0032] Furthermore, the length of the grinding plate 205 is greater than the distance between three adjacent rollers 2 on the blade grinding wheel 1.

[0033] The following description is based on Figure 1 Using the perspective reference, the side where the blade grinding carriage is labeled 1 is the front, and the opposite side is the rear:

[0034] Before the blade grinding carriage 1 grinds and polishes the blades, the operator first sets the grinding amount based on the wear amount of the outer surface of the wheel 2 during the grinding and polishing time. After the blade grinding carriage 1 drives the wheel 2 to grind the conveyed blades for a certain period of time, the grinding plate 205 moves laterally to perform quantitative grinding on the wheel 2. At this time, the blade grinding carriage 1 continues to drive the wheel 2 to rotate, and the operator does not need to stop the machine to disassemble the wheel 2 for grinding operations. This avoids frequent machine stops of the blade grinding carriage 1 and frequent disassembly and assembly of the wheel 2, which reduces the output of blades. It also ensures that the grinding amount of the outer surface of all wheel 2 is consistent, ensures that the outer surface of a single wheel 2 is uniform, and ensures the subsequent grinding and polishing quality of the blades.

[0035] The following describes the specific sanding details of sanding plate 205:

[0036] Initially, the grinding plate 205 and other components are located to the left of all the pulleys 2. The grinding amount is set manually based on the wear of the outer surface of the pulley 2 on the blade during the grinding and polishing time. Specifically, the manual operator uses a PLC controller or control panel connected to the electrical control components of this invention to lower the first electric slider 103, which drives the first fixed plate 104 and the components connected to the first fixed plate 104, onto the first slide rail 102 until the vertical distance from the center of the bottom surface of the grinding plate 205 to the outer surface of the pulley 2 equals the grinding amount. After the grinding plate 205 has descended to its position, the manual operator sets a timer. When the timer is triggered, the second electric slider 202 drives the second fixed frame 203 and the components connected to the second fixed frame 203 onto the second slide rail 202. The first electric slider 103 moves upward to the first fixed plate 104 and the components connected to the first fixed plate 104 descend on the first slide rail 102. The descending height is equal to the amount of grinding on the outer surface of the second wheel 2. Then, according to the above process, after the timer is triggered, the grinding plate 205 is reset to grind the outer surface of the wheel 2 by the second electric slider 202 and other components.

[0037] Specifically, by setting both the left and right ends of the bottom surface of the grinding plate 205 as upward-sloping surfaces, during the lateral movement of the grinding plate 205, the outer circular surface of the leather wheel 2 is first ground by the slope of the bottom surface of the grinding plate 205, avoiding interference between the side of the grinding plate 205 in the direction of travel being a flat surface. At the same time, the length of the grinding plate 205 is set to be greater than the distance between three adjacent leather wheels 2 on the blade grinding carriage 1. Thus, during the lateral movement of the grinding plate 205 to grind the outer circular surface of the leather wheel 2, the subsequent grinding surface of the grinding plate 205 can be used to grind the previously ground outer circular surface of the leather wheel 2 again as the grinding plate 205 moves laterally, ensuring grinding quality and eliminating the need for the grinding plate 205 to stay on the currently ground outer circular surface of the leather wheel 2 for a period of time, thereby improving grinding efficiency.

[0038] Example 2: Based on Example 1, such as Figures 5-7 As shown, it also includes a second fixing plate 301 detachably connected to the connecting seat 204; the front and rear sides of the second fixing plate 301 are each provided with two symmetrically distributed first connecting members 302; a first tension roller 303 is rotatably connected between each pair of front and rear opposite first connecting members 302, and the first tension roller 303 located on the left is connected to the output shaft of an external direct drive motor; eight rectangularly distributed second connecting members 304 are detachably connected to the second fixing plate 301; each pair of front and rear opposite second connecting members 304 is rotatably connected to... A second tension roller 305 is connected between two first tension rollers 303, with the bottom of the first tension roller 303 being higher than the bottom of the second tension roller 305. A grinding belt 306 is wound on the right-hand first tension roller 303, with the other end of the grinding belt 306 fixed to the left-hand first tension roller 303. The grinding belt 306 is in contact with all the second tension rollers 305, and the length of the grinding belt 306 between the two first tension rollers 303 is greater than the distance between three adjacent pulleys 2 on the blade grinding carriage 1.

[0039] Furthermore, the second connecting member 304 is configured as a spring telescopic rod with the telescopic end facing downwards; the second tension roller 305 is fixedly connected to the telescopic end of the second connecting member 304.

[0040] Furthermore, the second fixing plate 301 has a sliding groove 30101 on the left side of the front side and the left side of the rear side for the first connecting member 302 to slide; each of the two first connecting members 302 on the left is provided with a sliding block, which is located in the sliding groove 30101 on the corresponding side; a spring 307 is fixedly connected in the sliding groove 30101, and the other end of the spring 307 is fixedly connected to the sliding block of the first connecting member 302 located in the sliding groove 30101; the spring constant and deformation of the spring 307 are both smaller than those of the second connecting member 304.

[0041] In the grinding of the outer surface of the wheel 2 by the grinding plate 205 described in Example 1, as grinding progresses, the bottom surface of the grinding plate 205 experiences wear and grinding debris, affecting the grinding effect. Therefore, in this example, a grinding belt 306 is used instead of the grinding plate 205 to grind the outer surface of the wheel 2. The specific operation is as follows: Based on the specific grinding details of the grinding plate 205 in Example 1, the first electric slider 103 drives the first fixed plate 104 and the components connected to the first fixed plate 104 to descend on the first slide rail 102 via a PLC controller or control panel connected to the electrical control component of this invention. This lowers the vertical distance from the center of the bottom surface of the grinding belt 306 to the outer surface of the wheel 2 equal to the grinding amount. Then, the second electric slider 202 drives the second fixed frame 203 and the components connected to the second fixed frame 203 to move towards the wheel 2 on the second slide rail 201 to grind the outer surface of the wheel 2. In other words, regardless of whether the grinding plate 205 or the grinding belt 306 is used, the first part of the wheel 2 to be ground is the side edge of the wheel 2. As the grinding progresses, the outer surface of the wheel 2 is gradually ground. After the outer surface of the wheel 2 is ground multiple times with the grinding belt 306, the manual control of the external direct drive motor drives the first tension roller 303 on the left to wind up the old grinding belt 306. The new grinding belt 306 on the first tension roller 303 on the right is released under tension, and the first tension roller 303 on the right rotates, realizing the automatic replacement of the grinding belt 306 and extending the cycle of downtime to replace the grinding material.

[0042] Furthermore, when using the grinding plate 205 or the grinding belt 306 to grind the outer surface of the leather wheel 2, the grinding plate 205 or the grinding belt 306 must first grind the current outer surface of the leather wheel 2 before it can continue to move and grind the outer surface of the subsequent leather wheels 2, resulting in low grinding efficiency.

[0043] The following description is based on the second electric slider 202 driving the second fixed frame 203 and the components connected to the second fixed frame 203 to move from left to right, and is based on the rightmost second tension roller 305:

[0044] Specifically, by setting the second connecting member 304 as a spring telescopic rod, the abrasive belt 306 is initially in a tensioned state, and the spring 307 is in a compressed state. There is also a space for movement between the first connecting member 302 on the left and the left end of the slide groove 30101. When the second electric slider 202 and other components move the abrasive belt 306 to abrade the outer surface of the wheel 2, the rightmost second tensioning roller 305 will contact the side edge of the wheel 2 through the abrasive belt 306. As the abrasive belt 306 and other components move, the rightmost second tension roller 305 will be pressed upwards. Note that the contact point between the rightmost second tension roller 305 and the side edge of the pulley 2, separated by the abrasive belt 306, is located below it. The telescopic end of the second connecting piece 304 retracts to avoid this contact. At this time, the rightmost second tension roller 305, under the action of the second connecting piece 304, presses the abrasive belt 306 onto the outer surface of the pulley 2 to be abraded, causing the abrasive belt 306... The grinding belt 306 moves and grinds the wheel 2 that is currently being ground. As the second tension roller 305 is pressed upwards and the telescopic end of the second connector 304 retracts, the first connector 302 connected to the left first tension roller 303 moves away from the midpoint of the second fixed plate 301 along the groove on the second fixed plate 301 under the restoring force of the spring 307, maintaining the tension of the grinding belt 306. When the rightmost second tension roller 305 moves between the two leftmost wheels 2, the telescopic end of the second connector 304 pushes the rightmost second tension roller 305. 05. The second tension roller 305 moves downwards to reset. Since the stiffness coefficient and deformation of the second connecting member 304 are both greater than those of the spring 307, when the second tension roller 305 moves downwards to reset, it pushes the grinding belt 306 downwards, pulling the leftmost first tension roller 303 and its connected first connecting member 302 towards the midpoint of the second fixed plate 301, compressing the spring 307, thus ensuring the stable downward reset of the second tension roller 305. Furthermore, when the second tension roller 305 moves to between the two leftmost pulleys 2, as... Figure 7 As shown, since the outer surface of the pulley 2 is not yet fully polished, the abrasive belt 306 between the two rightmost second tension rollers 305 is restricted by the outer surface of the pulley 2 and moves upward. As polishing progresses, the diameter of the pulley 2 gradually decreases. Under the restoring force of the spring 307, the first connecting piece 302 connected to the left first tension roller 303 moves along the groove on the second fixed plate 301 away from the midpoint of the second fixed plate 301, keeping the abrasive belt 306 taut, that is, keeping the abrasive belt 306 in close contact with the pulley 2 for polishing, ensuring polishing quality. Note that during the polishing process, the abrasive belt 306 between two adjacent second tension rollers 305 is... Figure 7 The jacked-up state shown has been restored to Figure 6The initial state shown indicates that the grinding is complete. In summary, by setting the second connecting member 304 as a spring telescopic rod, when the grinding belt 306 moves to grind the outer surface of the wheel 2, the second tension roller 305 can be pressed upward to avoid it, and the grinding belt 306 moves and grinds the wheel 2 to be ground. When the second tension roller 305 moves between two adjacent wheels 2, the grinding belt 306 between the two adjacent second tension rollers 305 continues to grind the current wheel 2. Therefore, it is not necessary to grind the outer surface of the current wheel 2 first before moving to grind the outer surface of the subsequent wheel 2, thus improving the grinding efficiency.

[0045] Example 3: Based on Example 2, such as Figure 5 As shown, it also includes two suction covers 401 symmetrically arranged on the connecting seat 204, the two suction covers 401 being respectively located at the front end and rear end of the connecting seat 204.

[0046] Furthermore, the suction cover 401 is configured to be inclined toward the abrasive belt 306.

[0047] Furthermore, the suction port of the suction hood 401 is designed to be flared.

[0048] Considering that during the grinding process of the outer surface of the wheel 2, the flying debris generated during grinding pollutes the environment and is inconvenient for manual cleaning, and that the debris can easily get stuck in the power component of the present invention, causing the power component to jam; therefore, in this embodiment, the flying debris is treated by the suction cover 401. The specific operation is as follows: when the grinding belt 306 and other components move to grind the outer surface of the wheel 2, the connecting seat 204 drives the suction cover 401 to move synchronously, and at the same time, the external suction pump provides suction force to the suction cover 401 to remove the flying debris generated during grinding, so as to avoid the debris flying and polluting the environment, making it inconvenient for manual cleaning, and causing the power component of the present invention to jam.

[0049] Furthermore, by tilting the suction hood 401 toward the abrasive belt 306, it is easier to remove the downward-splashing debris, ensuring the debris removal effect. At the same time, the suction port of the suction hood 401 is set to be flared to increase the suction range of the suction hood 401.
