Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening devices, in particular to an automatic grinder for repairing a V-groove machine blade. Background Art

[0002] In the printing and packaging industry, the paper cutting blades required for the slotting of grey boards and paper cards need to be sharpened after being worn. Grinding machines are mostly used for sharpening. The operator manually adjusts the position and strength of the blade and grinds the slotting knife on the grinding wheel. Such operation is very dangerous. If you are not careful, the operator's fingers will be injured. There are also a lot of sparks splashing at the contact point between the blade and the grinding wheel, which can easily splash into the operator's eyes and damage vision. Fingers are prone to fatigue when holding the knife for a long time, and safety accidents are prone to occur. In the production process, a large number of blade tips break and break due to improper operation. These blades are thrown away, which is a waste of resources. If they are reused, it will take a long time to sharpen them. In the prior art, some auxiliary equipment is used to fix the blade with a metal frame, and then the blade is sharpened by contacting the grinding wheel. However, during the operation of this equipment, the operator needs to operate the machine at all times, which is time-consuming and labor-intensive. Therefore, an automatic grinder is needed that can automatically sharpen the knife, such as publication number CN213034209U, which discloses an automatic paper cutting blade sharpener, comprising a workbench, a grinding wheel sharpener arranged on the workbench, a blade fixing seat and a fixing seat driving assembly are also arranged on the workbench, and the gearbox of the fixing seat driving assembly is connected to the blade fixing frame of the blade fixing seat through a crank connecting rod mechanism, so as to realize mechanized control of continuous contact between the blade and the grinding wheel, and continuously sharpen the cutting edge of the blade through the offset force of the crank connecting rod mechanism and the translation of the slide rail, thereby finally achieving the technical effect of automatic sharpening.

[0003] However, the above-mentioned automatic paper cutting blade sharpener lacks a cooling device, and the existing cooling method is to cool the grinding position by pouring water through a water pipe. However, since the broken blade is to be reused, the unusable part of the tip of the broken blade must be polished to a suitable degree. In order to shorten the grinding time, a coarser grinding wheel is replaced, which increases the contact force between the blade and the grinding wheel. In this way, the entire blade will generate extremely high temperature if it is polished for a long time. If only the grinding position is cooled, the rest of the blade cannot be cooled, which will affect the hardness of the blade and cause the subsequent service life of the blade. Utility Model Content

[0020] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0021] As shown in the figure, this embodiment provides an automatic grinder for repairing a blade of a V-groove machine, comprising a workbench 1, on which an automatic feeding device 2 is provided, a cooling water tank 3 is provided at the top of the automatic feeding device 2, and a grinding device 4 is provided on one side of the cooling water tank 3; a mounting table 5 is provided in the cooling water tank 3, on which a clamping mechanism 6 for fixing a blade is fixedly installed, and the clamping mechanism 6 is entirely located in the cooling water tank 3. The clamping mechanism 6 is entirely arranged in the cooling water tank 3, and the cooling water is entirely submerged in the blade clamped by the clamping mechanism 6, so that the blade can be cooled as a whole, so that the blade does not generate high temperature to damage the internal structure, and the service life of the blade is increased.

[0022] A water outlet pipe 7 is provided on one side of the cooling water tank 3, and a water pump 8 is connected to the water outlet pipe 7. The water outlet of the water pump 8 is connected to a cooling pipe 9 and a drain pipe 10. The water outlet of the cooling pipe 9 is provided at the blade grinding position. The cooling water in the cooling water tank 3 is poured onto the grinding position by the water pump 8 to cool the blade grinding position.

[0023] A receiving tray 11 is provided on one side of the cooling water tank 3 at the blade grinding position, and the receiving tray 11 is located below the grinding wheel of the grinding device 4. The cooling water poured at the grinding position falls into the receiving tray 11 and then flows back into the cooling water tank 3.

[0024] The grinding debris will flow into the cooling water tank 3 and may damage the water pump 8. Therefore, a detachable filter plate 12 is provided in the cooling water tank 3 to filter the debris.

[0025] Since the blade head angle is fixed, the top of the mounting platform 5 is an inclined surface, and the inclination angle of the inclined surface is equal to the blade grinding angle.

[0026] Wherein, two clamping mechanisms 6 are provided on the mounting table; a certain angle is formed between the clamping mechanism 6 and the grinding wheel, and the two clamping mechanisms 6 are symmetrically arranged, so that blades with two opposite blade angles can be ground at the same time;

[0027] The clamping mechanism 6 comprises a clamping seat 13, on which a fixing groove 14 for placing a blade is provided, an adjusting mechanism is provided at the bottom end of the fixing groove 14, and a fixing mechanism is provided at the top end of the fixing groove 14;

[0028] Since the lengths of the blades are different, the lengths located in the fixed slot 14 are also different. Therefore, an adjusting spring 16 is connected to one side of the adjusting block 15, and the end of the adjusting spring 16 away from the adjusting block 15 is connected to the bottom end of the fixed slot 14. The adjusting block 15 is pressed by the blade to move in the fixed slot 14. After the blade is fixed by the fixing mechanism, the adjusting block 15 can press against the rear end of the blade under the action of the adjusting spring 16, so that the blade can move into the fixed slot 14.

[0029] The fixing mechanism includes a clamping block 17 and a fixing bolt 18 disposed at the top of the inner side of the fixing groove 14. The fixing bolt 18 is threadedly connected to the top of the clamping seat 13. The bottom end of the fixing bolt 18 penetrates the top of the clamping seat 13 and rotates in the fixing groove 14 to connect the clamping block 17. By rotating the fixing bolt 18, the clamping block 17 can be moved up and down, so that the blade can be fixed in the fixing groove 14.

[0030] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
