[0006] The embodiments of the utility model can be implemented as follows:

[0007] In a first aspect, the utility model provides a magnetic type knife grinder, comprising:

[0008] a base, a magnetic workbench and a supporting mechanism; the magnetic workbench is installed on the base, the side of the magnetic workbench away from the base is provided with a positioning inclined surface, and the magnetic workbench is rotatably connected with the base to adjust the included angle between the positioning inclined surface and the horizontal plane; the supporting mechanism is installed on the base, and the supporting mechanism is used to connect with the magnetic workbench to limit the rotation of the magnetic workbench close to the base.

[0009] In an optional embodiment, the supporting mechanism comprises a driver and a supporting block, the driver is installed on the base, the supporting block is installed on the driver and located between the magnetic workbench and the base, and the side of the supporting block away from the base is provided with a supporting inclined surface; the driver is used to drive the supporting block to move relative to the magnetic workbench to adjust the position where the supporting inclined surface contacts with the magnetic workbench, and then adjust the included angle between the positioning inclined surface and the horizontal plane.

[0010] Based on the above scheme, the support block is driven to move by the driver, the position of the support block between the magnetic workbench and the base is changed, and thus the angle adjustment of the positioning inclined surface is realized, and the operation is convenient.

[0011] In an optional embodiment, the driver is arranged in a linear telescopic structure, and the driver is used to drive the support block to linearly reciprocate relative to the base.

[0012] Based on the above scheme, when the inclination angle of the positioning inclined surface needs to be adjusted, the driver is started, the support block is driven to move along the set straight line, the insertion depth of the support block into the magnetic workbench increases, the position of the support inclined surface contacting the magnetic workbench gradually increases, and the magnetic workbench rotates away from the base, and the angle with the horizontal plane decreases. Similarly, when the support block is driven to slide away from the magnetic workbench, the insertion depth of the support block into the magnetic workbench decreases, the position of the support inclined surface contacting the magnetic workbench gradually decreases, the magnetic workbench rotates towards the base, and the angle with the horizontal plane gradually increases. In this way, the angle adjustment of the positioning inclined surface is convenient and fast.

[0013] In an optional embodiment, the number of the support blocks is multiple, and the inclination angles of the support inclined surfaces of each support block are different; the multiple support blocks are connected with the driver, and the driver is used to drive the multiple support blocks to rotate around the preset axis, so as to selectively make one of the multiple support blocks located between the magnetic workbench and the base.

[0014] Based on the above scheme, the multiple support blocks are driven to rotate by the driver, and the corresponding support blocks are rotated to below the magnetic workbench and the base, the magnetic workbench is supported by the support blocks, and the angle adjustment of the positioning inclined surface of the magnetic workbench is realized at the same time, and the operation is convenient.

[0015] In an optional embodiment, the multiple support blocks are uniformly and spacedly arranged in the circumferential direction of the preset axis.

[0016] Based on the above scheme, the included angles of any adjacent support blocks are equal, the position of the support block is accurately adjusted by controlling the rotation angle of the driver, the position adjustment of the support block is convenient, the required time for adjustment is less, and the adjustment efficiency is high.

[0017] In an optional embodiment, the support mechanism further comprises a fixing ring, the fixing ring is sleeved outside the rotating shaft of the driver, the fixing ring and the rotating shaft are relatively fixed in the circumferential direction of the rotating shaft, and one end of the multiple support blocks is fixed to the fixing ring and spacedly arranged in the circumferential direction of the fixing ring.

[0018] Based on the above solution, multiple support blocks are connected to the fixed ring, and multiple support blocks and the fixed ring are integrated together. After the fixed ring and the rotating shaft are installed, the assembly of multiple support blocks and the rotating shaft is completed, which reduces the assembly difficulty and improves the assembly efficiency.

[0019] In an optional embodiment, the support mechanism also includes an anti-interference ring, and the plurality of support blocks are located in the area enclosed by the anti-interference ring and are fixedly connected to the anti-interference ring; the lower side of the support slope of each support block is located on the end face of the anti-interference ring away from the base; the anti-interference ring is located between the magnetic workbench and the base.

[0020] Based on the above solution, by arranging anti-interference rings on the outside of multiple support blocks, when the multiple support blocks are driven to rotate by the driver to adjust the position of the support blocks relative to the magnetic workbench, the anti-interference rings are always located between the magnetic workbench and the base. The magnetic workbench will not fit with the base, resulting in the support blocks being unable to enter between the magnetic workbench and the base. Therefore, it is not easy for the magnetic workbench and the support blocks to interfere with each other, and the angle adjustment of the magnetic workbench is flexible and reliable.

[0021] In an optional embodiment, the fixing ring is fixedly connected to the rotating shaft via a spline.

[0022] Based on the above solution, the assembly structure of the fixed ring and the rotating shaft is simple, and the combination is firm and reliable.

[0023] In an optional embodiment, the magnetic knife sharpener further includes a wire drum and a cable, wherein the wire drum is rotatably engaged with the base, one end of the cable is connected to the magnetic workbench, and the other end is connected to the wire drum, and the cable is used to limit the magnetic workbench from rotating in a direction away from the base.

[0024] Based on this solution, when the magnetic worktable rotates toward the base, the cable relaxes, and the cable reel rotates to straighten it, thereby locking the magnetic worktable with the cable and preventing it from rotating away from the base. To rotate the magnetic worktable away from the base, the cable reel rotates first, loosening the cable to prevent it from restricting the magnetic worktable's rotation. Once the magnetic worktable's position is adjusted, the cable reel rotates in the opposite direction, causing it to straighten the cable, allowing the cable to stabilize the magnetic worktable's position.

[0025] In an optional embodiment, the magnetic knife sharpener further includes a knife sharpening mechanism, and the knife sharpening mechanism is installed on the base.

[0026] Based on the above solution, the knife sharpening mechanism can be used to sharpen the knife adsorbed on the magnetic workbench.

[0027] The beneficial effects of the embodiments of the present invention include, for example:

[0028] In summary, the magnetic type knife grinder provided by the embodiment utilizes the magnetic adsorption workbench to magnetically adsorb the knife to be polished, so that the knife to be polished is fixed on the magnetic adsorption workbench, displacement is not prone to occur during polishing, and safety is improved. According to different models of the knife to be polished, the magnetic adsorption workbench is rotated to adjust the angle of the positioning inclined surface of the magnetic adsorption workbench. After the angle of the positioning inclined surface changes, the position of the knife to be polished changes correspondingly after the knife to be polished is placed on the positioning inclined surface, so that the polishing requirement is met. Meanwhile, after the position of the magnetic adsorption workbench is adjusted, the supporting mechanism is operated to cooperate with the magnetic adsorption workbench, so as to support the magnetic adsorption workbench, prevent the magnetic adsorption workbench from rotating towards the base to change the angle, and stabilize the angle of the positioning inclined surface during polishing, so that the angle of the knife to be polished is fixed and the polishing quality is high.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0038] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0042] In the prior art, the tool is positioned by suction on the workbench, and the tool is polished by the grinding wheel. Due to the different types of tools, the thickness and edge angle of the tool are different, and the angle between the tool and the grinding wheel needs to be adjusted during polishing. Since the tool is positioned by the workbench, different angle workbenches need to be designed, and the tool needs to be repeatedly positioned on different workbenches, which is complicated and has positioning errors, reducing the polishing quality and efficiency.

[0043] Therefore, the designer provides a magnetic knife sharpener which can adjust the state of the magnetic workbench according to different types of knives, adapt to the grinding of knives in different scenes, and does not need to set multiple magnetic workbenches 200, saving space and improving the grinding efficiency and quality without repeatedly adjusting the knives between multiple workbenches.

[0044] Please refer to Figures 1-3 In the embodiment, the magnetic knife sharpener comprises a base 100, a magnetic workbench 200 and a supporting mechanism 300. The magnetic workbench 200 is installed on the base 100, and the side of the magnetic workbench 200 away from the base 100 is provided with a positioning slope 210. The magnetic workbench 200 is rotatably connected with the base 100 to adjust the angle between the positioning slope 210 and the horizontal plane. The supporting mechanism 300 is installed on the base 100 and is used to connect with the magnetic workbench 200 to limit the rotation of the magnetic workbench 200 towards the base 100.

[0045] As described above, the working mode of the magnetic knife sharpener provided by the embodiment is as follows:

[0046] The magnetic workbench 200 is used to magnetically attract the knife to be ground, so that the knife to be ground is fixed on the magnetic workbench 200 and is not easy to displace during grinding, improving the safety. According to the different types of the knife to be ground, the magnetic workbench 200 is rotated to adjust the angle of the positioning slope 210 of the magnetic workbench 200. After the angle of the positioning slope 210 changes, the position of the knife to be ground changes correspondingly when the knife to be ground is placed on the positioning slope 210, thereby meeting the grinding requirements. Meanwhile, after the position of the magnetic workbench 200 is adjusted, the supporting mechanism 300 is operated to cooperate with the magnetic workbench 200 to support the magnetic workbench 200, preventing the magnetic workbench 200 from rotating towards the base 100 to change the angle. During grinding, the angle of the positioning slope 210 is stable, and the angle of the knife to be ground is fixed, improving the grinding quality.

[0047] The details of the magnetic knife sharpener of the embodiment are described below by way of example.

[0048] In the embodiment, the supporting mechanism 300 comprises a driver 310 and a supporting block 320. The driver 310 is installed on the base 100, and the supporting block 320 is installed on the driver 310 and located between the magnetic workbench 200 and the base 100. The side of the supporting block 320 away from the base 100 is provided with a supporting slope 321. The driver 310 is used to drive the supporting block 320 to move relative to the magnetic workbench 200 to adjust the position where the supporting slope 321 contacts with the magnetic workbench 200, thereby adjusting the angle between the positioning slope 210 and the horizontal plane.

[0049] It should be understood that the driving of the support block 320 by the driver 310 changes the position of the support block 320 between the magnetic workbench 200 and the base 100, and the position of the support slope 321 in contact with the magnetic workbench 200, and the support height of the support slope 321 is changed accordingly, so as to realize the angle adjustment of the positioning slope 210, and the operation is convenient. When the support block 320 is supported between the magnetic workbench 200 and the base 100, the bottom surface of the support block 320 is attached to the base 100, and the top surface is the support slope 321, and the support slope 321 is in contact with the magnetic workbench 200.

[0050] In one embodiment, the driver 310 is provided in a linear telescopic structure, and the driver 310 is used to drive the support block 320 to linearly reciprocate relative to the base 100. When the inclination angle of the positioning slope 210 needs to be adjusted, the driver 310 is started, and the driver 310 drives the support block 320 to move along the set straight line, the depth of the support block 320 inserted into the magnetic workbench 200 increases, the position of the support slope 321 in contact with the magnetic workbench 200 gradually increases, and the magnetic workbench 200 rotates away from the base 100, and the angle with the horizontal plane decreases. Similarly, when the driver 310 drives the support block 320 to slide away from the magnetic workbench 200, the depth of the support block 320 inserted into the magnetic workbench 200 decreases, the position of the support slope 321 in contact with the magnetic workbench 200 gradually decreases, and the magnetic workbench 200 rotates towards the base 100, and the angle with the horizontal plane gradually increases. In this way, the angle adjustment of the positioning slope 210 is convenient and fast.

[0051] It should be understood that the linear telescopic structure can be a pneumatic cylinder or a hydraulic cylinder.

[0052] Please refer to Figures 1-4 In another embodiment, the number of support blocks 320 is multiple, and the inclination angles of the support slopes 321 of each support block 320 are different. The multiple support blocks 320 are connected with the driver 310, and the driver 310 is used to drive the multiple support blocks to rotate around a preset axis, so as to selectively make one of the multiple support blocks 320 located between the magnetic workbench 200 and the base 100. Wherein, the preset axis coincides with the axis of the rotating shaft.

[0053] In this way, the driving of the multiple support blocks 320 by the driver 310 makes the corresponding support block 320 rotate to below the magnetic workbench 200, and the magnetic workbench 200 is supported by the support block 320, and the angle adjustment of the positioning slope 210 of the magnetic workbench 200 is realized, and the operation is convenient.

[0054] Further, the plurality of support blocks 320 are evenly spaced in the circumferential direction of the preset axis. The included angle of any adjacent support blocks 320 is equal, facilitating accurate adjustment of the position of the support blocks 320 by controlling the rotation angle of the driver 310. The position of the support blocks 320 is conveniently adjusted, requiring less time and having high adjustment efficiency. For example, the number of support blocks 320 is three, the three support blocks 320 are evenly spaced in the circumferential direction of the preset axis, the included angle between adjacent support blocks 320 is 120°, and the driver 310 can be a motor. When the rotating shaft of the driver 310 rotates to adjust the position of the support blocks 320, the rotation angle is conveniently controlled.

[0055] Notably, Figure 1 The position where the dashed line shown in FIG. 2 intersects with the support inclined surface 321 of the support block 320 is the position where the support inclined surface 321 of the support block 320 contacts the magnetic workbench 200. The radius of the position where the support inclined surface 321 of each support block 320 contacts the magnetic workbench 200 is the same. Since the inclination angles of the support inclined surfaces 321 are different, the heights of the support inclined surfaces 321 at the same radius position are different, so that the angle adjustment of the magnetic workbench 200 can be achieved.

[0056] Optionally, the support mechanism 300 further comprises a fixing ring 330, the fixing ring 330 is sleeved outside the rotating shaft of the driver 310, and the fixing ring 330 is fixed relative to the rotating shaft in the circumferential direction of the rotating shaft. One end of each of the plurality of support blocks 320 is fixed to the fixing ring 330 and spaced in the circumferential direction of the fixing ring 330. Each of the plurality of support blocks 320 is connected to the fixing ring 330, and the plurality of support blocks 320 and the fixing ring 330 are integrated together. After the fixing ring 330 is installed with the rotating shaft, the assembly of the plurality of support blocks 320 and the rotating shaft is completed, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0057] It should be understood that each of the plurality of support blocks 320 can be welded outside the fixing ring 330. Moreover, the fixing ring 330 can be a circular ring, and the fixing ring 330 can be fixedly connected to the rotating shaft by using a spline. When the rotating shaft rotates, the fixing ring 330 and the plurality of support blocks 320 can rotate together. In addition, each support block 320 can be a right-angled triangular plate, and the inclined surface of the right-angled triangular plate is the support inclined surface 321. Obviously, in order to improve the support stability, the thickness of the right-angled triangular plate can be increased, for example, the thickness of the right-angled triangular plate can be between 50 mm and 100 mm.

[0058] Optionally, the support mechanism 300 further comprises an anti-interference ring 340, the anti-interference ring 340 is a circular ring, and each of the plurality of support blocks 320 is located in the area surrounded by the anti-interference ring 340 and is fixedly connected to the anti-interference ring 340. The lower side of the support inclined surface 321 of each support block 320 is located on the end surface of the anti-interference ring 340 away from the base 100, and the anti-interference ring 340 is located between the magnetic workbench 200 and the base 100.

[0059] It should be understood that by arranging the anti-interference ring 340 outside the plurality of support blocks 320, when the plurality of support blocks 320 are driven to rotate by the driver 310 to adjust the position of the support blocks 320 relative to the magnetic workbench 200, the anti-interference ring 340 is always located between the magnetic workbench 200 and the base 100, and the magnetic workbench 200 and the base 100 cannot be bonded, which causes the support blocks 320 to be unable to enter between the magnetic workbench 200 and the base 100, thereby avoiding the magnetic workbench 200 and the support blocks 320 from interfering with each other, and the angle adjustment of the magnetic workbench 200 is flexible and reliable.

[0060] Please refer to Figures 1-3 In this embodiment, optionally, the magnetic knife sharpener further comprises a wire reel and a cable 400, the wire reel is rotatably connected with the base 100, one end of the cable 400 is connected with the magnetic workbench 200, and the other end of the cable 400 is connected with the wire reel, and the cable 400 is used to limit the rotation of the magnetic workbench 200 away from the base 100. The wire reel can be driven by a motor, and the operation is flexible.

[0061] When the magnetic workbench 200 rotates towards the base 100, the cable 400 is relaxed, the wire reel is rotated to make the cable 400 straight, so as to lock the magnetic workbench 200 through the cable 400, and avoid the magnetic workbench 200 from rotating away from the base 100. When it is needed to rotate the magnetic workbench 200 away from the base 100, the wire reel is first rotated to relax the cable 400, so as to prevent the cable 400 from limiting the rotation of the magnetic workbench 200, and when the position adjustment of the magnetic workbench 200 is completed, the wire reel is reversely rotated to make the cable 400 straight, and the position of the magnetic workbench 200 is stabilized by the cable 400.

[0062] In addition, the wire reel and the cable 400 can be arranged on both sides of the magnetic workbench 200 to improve the stability.

[0063] In order to facilitate the connection between the cable 400 and the magnetic workbench 200, a convex column 220 can be installed on the magnetic workbench 200, and the cable 400 is connected with the convex column 220.

[0064] In this embodiment, optionally, the magnetic knife sharpener further comprises a knife sharpening mechanism 500, and the knife sharpening mechanism 500 is installed on the base 100. The knife sharpening mechanism 500 can be used to perform the sharpening operation on the knife adsorbed on the magnetic workbench 200.

[0065] It should be noted that a magnet is arranged inside the magnetic workbench 200, and the magnet can be an electromagnet, which can magnetically adsorb and fix the knife on the positioning slope 210. Since the electromagnet is used, the magnetic force can be controlled, and the magnetism of the magnetic workbench 200 can be lost by being powered off when the adsorption and positioning are not needed, so that the knife can be conveniently taken and placed.

[0066] In addition, the grinding mechanism 500 can adopt a known structure, the grinding wheel of the grinding mechanism 500 can be driven by a motor, and the grinding wheel can also be adjusted in position by a three-dimensional moving platform, so that different positions of the tool can be polished, and the use is flexible.

[0067] The magnetic type grinding machine provided in the embodiment can drive the support block 320 to move through the driver 310 after positioning the tool, thereby adaptively adjusting the angle of the magnetic workbench 200, achieving adjustment of the angle of the tool, and having wide use range, flexible and convenient use.

[0068] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
