Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing equipment, and in particular to an adjustable grinding wheel dressing device for a cutting machine grinding wheel. Background Art

[0002] In the process of tobacco processing, the cigarette factory needs to use a shredder to cut the processed tobacco sheets or stems into leaf shreds or stem shreds of specified standard sizes. The shredder is equipped with a knife roller, and multiple blades are arranged on the periphery of the knife roller. The knife roller rotates to cut the material. After the equipment has been running for a long time, it needs to be stopped and the blades need to be ground with the help of a grinding wheel. In the process of grinding the blades, the grinding wheel rotates while moving along the blade to complete the grinding of the blades, and the blades are ground on the periphery of the grinding wheel. Therefore, the peripheral size of the grinding wheel determines the degree of grinding of the blades, and then can determine the effective cutting outer diameter of the blade when the blade rotates, which represents the knife gate clearance. The knife gate clearance is an important indicator in the operation of the shredder. In the above, in order to adjust the peripheral size of the grinding wheel, keep the periphery of the grinding wheel flat, and improve the grinding effect, it is actually achieved by relying on the periphery of the diamond grinding wheel, such as Figure 1 As shown, a base 1-1 is installed on the equipment, and a row of diamonds 1-2 are arranged on the base 1-1 to grind the periphery of the grinding wheel. The base 1-1 is connected to the equipment through a threaded rod. The threaded rod is screwed and different numbers of gaskets are placed between the base 1-1 and the equipment to adjust the height of the diamonds 1-2. The adjustment accuracy of this gasket-type adjustment method is relatively low, and sometimes it cannot meet the production process requirements for the knife gate clearance. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] like Figure 2-Figure 5As shown, the embodiment of the present application provides an adjustable grinding wheel dressing device for a shredder grinding wheel, which is applied to a shredder. In actual production, a cigarette factory needs to use a shredder to cut tobacco sheets and other materials, and cut the tobacco sheets into shreds that meet standard requirements. During the cutting process, the knife gate gap, an indicator, affects the cutting quality. In addition, a knife roller is provided on the shredder, and a plurality of blades are evenly arranged on the periphery of the knife roller. The direction of the blade edge is parallel to the axis of the knife roller. When the knife roller rotates, the plurality of blades can rotate and cut the material. After the shredder has been running for a long time, the blade needs to be ground, and the grinding is performed using a grinding wheel. When grinding, the shredder is first stopped, and the grinding wheel rotates rapidly and moves along the blade edge. Move so that the outer periphery of the grinding wheel can grind the blade. In addition, a grinding wheel dressing device will be set on the equipment. The grinding wheel dressing device is mostly diamond. The diamond grinds the outer periphery of the grinding wheel to change the overall circumferential size of the grinding wheel, and then the degree of grinding of the blade by the grinding wheel can be adjusted to adjust the effective cutting circumferential outer diameter of the outermost blade when the blade rotates. The effective cutting circumferential outer diameter is an indicator of the knife gate clearance. That is, by adjusting the position height of the diamond, the grinding adjustment of the outer periphery of the grinding wheel is realized to achieve the adjustment of the knife gate clearance indicator, so that the cutting process of the wire cutter meets the standard requirements. At the same time, the diamond grinding makes the outer periphery of the grinding wheel smoother and improves the effect of grinding the blade.

[0027] At present, the adjustment of diamond is as follows: Figure 1 As shown, a base 1-1 is provided, a row of diamonds 1-2 are provided on the base 1-1, and a threaded column is also provided on the base 1-1, which is screwed on a device such as a wire cutter to achieve fixed installation of the base 1-1. By screwing the threaded column on the device, and arranging different numbers of gaskets between the base 1-1 and the device, and then tightening, the height of the base 1-1 protruding from the device can be adjusted, so as to adjust the grinding degree of the grinding wheel by the diamonds 1-2 on the base 1-1, thereby adjusting the knife door gap index. However, this adjustment method is limited by the gasket. The thickness has a relatively low adjustment accuracy and is a stage-by-stage adjustment, which cannot be adjusted more finely. During the production process, there will be a situation where the production process requirements for the knife gate gap cannot be met. The present application aims to improve the fineness of adjusting the diamond 1-2 so that the adjusted knife gate gap can meet the needs of more production processes. In addition, since the diamonds 1-2 on the base 1-1 are arranged in rows at this stage, the heights of the diamonds 1-2 are not uniform, and a gap will be generated when contacting the grinding wheel. The gap is prone to accumulate smoke scale, which affects the effect of dressing the grinding wheel.

[0028] The adjustable grinding wheel dressing device for a wire cutter grinding wheel comprises a first base body 1 and a second base body 2. The first base body 1 is used to be installed at a preset position, such as being installed on a wire cutter or other machine frame. A receiving cavity 100 is arranged on the first base body 1. The second base body 2 can move in the receiving cavity 100 of the first base body 1. At least part of the second base body 2 extends out of the receiving cavity 100. When the second base body 2 moves in the receiving cavity 100 of the first base body 1, the length of the part of the second base body 2 extending out of the receiving cavity 100 can be changed. The device also comprises a fastening device.

[0029] The grinding assembly 40 is disposed on the portion of the second base body 2 extending out of the accommodating cavity 100 .

[0030] In this embodiment, the first seat body 1 is installed on the wire cutting machine. By changing the distance of the grinding assembly 40 away from the first seat body 1, the grinding degree of the grinding wheel can be changed, thereby realizing the adjustment of the knife door clearance index. Moreover, the second seat body 2 is free to move relative to the first seat body 1.
