Description

Technical Field

[0001] This utility model relates to the field of knife sharpening machine technology, specifically to industrial knife sharpening machines. Background Technology

[0002] Industrial knife sharpening machines are devices specifically designed for sharpening various types of knives. They use a high-speed rotating grinding wheel to contact the cutting edge of the knife, removing the dull layer and reshaping the sharp edge through grinding. They are widely used in manufacturing, forestry, printing, papermaking and many other fields.

[0003] Currently, sharpening is performed by rotating a grinding wheel at high speed. However, it is inconvenient to support the tool during the sharpening process, as the tool must be held by hand. This is quite inconvenient. If a tool holder is used to support the tool, the grinding wheel will wear down after a period of use. Once the grinding wheel is worn down, it is difficult to adjust the position of the tool holder, which affects the subsequent sharpening effect.

[0004] An industrial knife sharpening machine was proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an industrial knife sharpening machine to solve the problems mentioned in the background art. Currently, knife sharpening is carried out by high-speed rotation of the grinding wheel. During the sharpening process, it is inconvenient to support the knife and requires holding the knife by hand, which is quite inconvenient. If a knife holder is directly set to support the knife, the grinding wheel will wear down after a period of use. After the grinding wheel wears down, it is not easy to adjust the position of the knife holder, which affects the subsequent sharpening effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial knife sharpening machine, including a base;

[0007] The base has two sets of feet symmetrically installed at its bottom;

[0008] Also includes:

[0009] The top of the base is fixedly mounted with a housing, and the top of the housing is hinged with a handle. Support frames are symmetrically mounted on the top of the base inside the housing, and the two support frames are rotatably connected to a rotating shaft inside.

[0010] A servo motor is fixedly installed above one of the support frames, and the output end of the servo motor passes through one of the support frames and is fixedly connected to the rotating shaft. One end of the rotating shaft passes through the other support frame and is fixedly installed with a diamond grinding wheel.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this industrial knife sharpening machine makes it easier to support the knife during sharpening, and when the diamond grinding wheel wears down after a period of use, the height of the fixing frame and the sharpening machine can be adjusted to avoid excessive distance between the knife and the diamond grinding wheel after it is placed in the sharpening groove, thus avoiding affecting the sharpening effect. The specific details are as follows:

[0019] 1. When sharpening a tool, place the cutting edge of the tool on the sharpening stand. Start the servo motor to drive the rotating shaft to rotate on the support frame, which in turn drives the diamond grinding wheel to rotate. After the tool is placed, the cutting edge of the tool is on the left side of the fixed frame. Move the tool from left to right on the fixed frame so that the entire cutting edge of the tool passes through the sharpening groove on the fixed frame, allowing the cutting edge of the tool to contact the diamond grinding wheel and complete the sharpening operation. When the diamond grinding wheel wears, rotate the positioning stud to remove the positioning of the movable frame. Rotate the knob to drive the screw to rotate. After the screw rotates, it can drive the movable frame to move through the connection with the threaded groove. The height of the movable frame can be adjusted, which allows the height of the fixed frame and the sharpening stand to be adjusted. After adjustment, tighten the positioning stud to position the movable frame, which facilitates the support of the tool when sharpening. After a period of use, when the diamond grinding wheel wears, the height of the fixed frame and the sharpening stand can be adjusted to avoid the gap between the tool and the diamond grinding wheel being too large after the diamond grinding wheel is placed in the sharpening groove, thus avoiding affecting the sharpening effect.

[0020] 2. During sharpening, the chips on the diamond grinding wheel can enter the collection box through the discharge groove. The collection box collects the chips. When cleaning the collection box, it can be pulled out to detach the connecting strip from the U-shaped clip, allowing the collection box to be removed for cleaning. When installing the collection box, insert the connecting strip into the U-shaped clip so that one end of the connecting strip is attracted to the magnet, completing the installation of the collection box. This allows for the collection of chips, facilitating subsequent centralized cleaning. Attached Figure Description

A bevel is provided on the upper front of the housing 101, and a through groove 108 is provided through the bevel on one side of the diamond grinding wheel 106. This makes it easy to support the tool when sharpening it. When the diamond grinding wheel 106 wears down after a period of use, the height of the fixing frame 110 and the sharpening frame 111 can be adjusted to prevent the gap between the tool and the diamond grinding wheel 106 from being too large after the tool is placed in the sharpening groove 112 when the diamond grinding wheel 106 wears down, so as to avoid affecting the sharpening effect.

[0029] An adjusting frame 109 is provided on one side of the diamond grinding wheel 106, and a fixed frame 110 is fixedly installed on one side of the adjusting frame 109. A sharpening holder 111 is fixedly installed on one side of the fixed frame 110. A sharpening groove 112 is formed on the top of the fixed frame 110 and the sharpening holder 111. An adjusting assembly 2 is provided below the adjusting frame 109 to support the cutting tool. The adjusting assembly 2 includes a base plate 201 fixedly installed on the top of the base 1 and located below the adjusting frame 109. A cylinder 202 is fixedly installed on the top of the base plate 201. A movable frame 203 is slidably connected inside the cylinder 202 and is fixedly connected to the adjusting frame 109, allowing adjustment of the height of the adjusting frame 109. A screw 204 is rotatably connected to the bottom of the cylinder 202.

[0030] Working principle: Before using this industrial knife sharpening machine, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, when sharpening a tool is required, the cutting edge of the tool is placed on the sharpening holder 111. The servo motor 107 is started to drive the rotating shaft 105 to rotate on the support frame 104, which in turn drives the diamond grinding wheel 106 to rotate. After the tool is placed, the cutting edge is on the left side of the fixed frame 110. The tool is moved from left to right on the fixed frame 110, so that the entire cutting edge of the tool passes through the sharpening groove 112 on the fixed frame 110, and the cutting edge of the tool can contact the diamond grinding wheel 106 to complete the sharpening operation. When the diamond grinding wheel 106 wears, the positioning stud 208 is rotated so that the movable frame 203 is no longer positioned. The knob 2 is then rotated. 07 drives the screw 204 to rotate. After the screw 204 rotates, it can drive the movable frame 203 to move through the connection with the threaded groove 205. The height of the movable frame 203 can be adjusted, so that the height of the fixed frame 110 and the grinding frame 111 can be adjusted. After adjustment, tighten the positioning stud 208 to position the movable frame 203, so that the tool can be supported when grinding. After a period of use, when the diamond grinding wheel 106 wears, the height of the fixed frame 110 and the grinding frame 111 can be adjusted to avoid the gap between the tool and the diamond grinding wheel 106 after the tool is put into the grinding groove 112 when the diamond grinding wheel 106 wears out, so as to avoid affecting the grinding effect.

[0031] During sharpening, the debris on the diamond grinding wheel 106 can enter the collection box 114 through the discharge groove 113. The collection box 114 collects the debris. When cleaning the collection box 114, it can be pulled out directly, causing the connecting strip 115 to detach from the U-shaped clip 116. The collection box 114 can then be removed for cleaning. When installing the collection box 114, the connecting strip 115 is inserted into the U-shaped clip 116. The connecting strip 115 is made of metal, and one end of the connecting strip 115 is attracted to the magnet block 117, completing the installation of the collection box 114. This allows for the collection of debris, facilitating subsequent centralized cleaning.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
