Description

Technical Field

[0001] This utility model relates to the field of filter paper roll cutting technology, and specifically to a filter paper roll cutting mechanism. Background Technology

[0002] When producing automotive filter paper, large filter paper rolls need to be cut into smaller ones. The filter paper wrapped around the large roll is released, cut by a roller cutter, and then rolled back up to form smaller filter paper rolls. Existing roller cutters need to be removed and polished after a period of use to ensure they are sharp enough to make the cut ends of the filter paper flat. However, a set of equipment has a large number of roller cutters, and removing them all is cumbersome and delays the production schedule. Utility Model Content

[0003] The purpose of this invention is to provide a filter paper roll cutting mechanism to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter paper roll cutting mechanism, comprising: a base, side plates fixedly connected to the top two sides of the base, a rotating shaft rotatably arranged between the two side plates, a plurality of roller cutters arranged at equal intervals on the rotating shaft, a slider slidably arranged on the top of the base, a plurality of grinding components corresponding to the roller cutters arranged at equal intervals on the slider, the grinding components comprising a fixed grinding frame fixedly installed on the slider and a movable grinding frame slidably arranged on the top of the slider, and wedge-shaped grinding stones fixedly connected to the sides of the fixed grinding frame and the movable grinding frame that are close to each other.

[0005] Furthermore, the top of the slider is fixedly connected to two limiting edges, and the fixed grinding frame and the movable grinding frame are disposed between the two limiting edges. The fixed grinding frame is fixedly connected to the top of the slider by a corner bracket.

[0006] Furthermore, a mounting post is fixedly connected to the top of the slider. The mounting post is located on the side of the movable grinding frame away from the fixed grinding frame. A screw is threaded onto the mounting post, and one end of the screw passes through the mounting post and is connected to the side of the movable grinding frame through a bearing.

[0007] Furthermore, a lubricating sponge block is fixedly connected to each of the fixed grinding frame and the movable grinding frame on their respective sides, and the lubricating sponge block is located above the wedge-shaped grinding stone.

[0008] Furthermore, a liquid filling groove is provided on the top of the lubricating sponge block.

[0009] Furthermore, the inclined surface of the wedge-shaped polishing stone is parallel to the inclined surface of the cutting edge of the hob.

[0010] Furthermore, two feed rollers for conveying filter paper are rotatably arranged between the two side plates, and the roller is located between the two feed rollers and is in close contact with the filter paper.

[0011] The filter paper roll cutting mechanism provided by this utility model has the following advantages in the above technical solution:

[0012] This invention enables grinding of the hob without removing it by setting a grinding component on one side of the hob, allowing it to be put into use more quickly, reducing the labor intensity of workers, and increasing processing speed.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 A filter paper roll cutting mechanism includes: a base 1, with side plates 2 fixedly connected to both sides of the top of the base 1, a rotating shaft 4 rotatably arranged between the side plates 2, a plurality of roller cutters 41 evenly spaced on the rotating shaft 4, a slider 5 slidably arranged on the top of the base 1, a driving device 6 fixedly installed on the top of the base 1, the movable end of the driving device 6 being fixedly connected to one side of the slider 5, the driving device 6 being a dual-axis cylinder, and a plurality of grinding components corresponding to the roller cutters 41 evenly spaced on the slider 5, the grinding components including a fixed grinding frame 71 fixedly installed on the slider 5 and a slidably arranged on the top of the slider 5. The movable grinding frame 72 is fixedly connected to three guide rods 73. The other end of the guide rods 73 is inserted into the fixed grinding frame 71 to enhance the stability of the movable grinding frame 72 when it moves. Wedge-shaped grinding stones 74 are fixedly connected to the sides of the fixed grinding frame 71 and the movable grinding frame 72 that are close to each other. By moving the movable grinding frame 72, the distance between the fixed grinding frame 71 and the movable grinding frame 72 is changed to compensate for the displacement caused by the wear of the wedge-shaped grinding stones 74 during grinding, so that the two wedge-shaped grinding stones 74 can effectively grind the hob 41.

[0024] Furthermore, two limiting ridges 51 are fixedly connected to the top of the slider 5. The fixed grinding frame 71 and the movable grinding frame 72 are arranged between the two limiting ridges 51. The fixed grinding frame 71 is fixedly connected to the top of the slider 5 by a bracket 711. A mounting post 8 is fixedly connected to the top of the slider 5. The mounting post 8 is located on the side of the movable grinding frame 72 away from the fixed grinding frame 71. A screw 81 is threaded onto the mounting post 8. One end of the screw 81 passes through the mounting post 8 and is connected to the side of the movable grinding frame 72 by a bearing. The inner ring of the bearing is fixedly sleeved on the outside of the screw 81. The outer ring of the bearing is embedded in the movable grinding frame 72. By rotating the screw 81, the screw 81 can be screwed in or out, thereby driving the movable grinding frame 72 to move back and forth on the top surface of the slider 5.

[0025] Furthermore, a lubricating sponge block 75 is fixedly connected to each of the fixed grinding frame 71 and the movable grinding frame 72 on their respective sides. The lubricating sponge block 75 is located above the wedge-shaped grinding stone 74. A liquid filling groove 751 is opened on the top of the lubricating sponge block 75. The inclined surface of the wedge-shaped grinding stone 74 is parallel to the inclined surface of the cutting edge of the hob 41. By injecting grinding lubricating fluid into the liquid filling groove 751, the grinding lubricating fluid diffuses in the lubricating sponge block 75. When the hob 41 rotates and passes through the lubricating sponge block 75, the grinding lubricating fluid adheres to the outer side of the cutting edge of the hob 41, thereby enhancing the grinding effect of the hob 41 in the two wedge-shaped grinding stones 74.

[0026] Furthermore, two feeding rollers for conveying filter paper 3 are rotatably arranged between the two side plates 2. The roller 41 is located between the two feeding rollers and is close to the filter paper 3. The two feeding rollers support the filter paper 3, so that there is a squeezing force between the roller 41 and the filter paper 3, which makes it easier for the roller 41 to cut the filter paper 3.

[0027] In this utility model, by installing the grinding components on the top of the slider 5, the slider 5 drives multiple grinding components to approach or move away from the hob 41. When the hob 41 needs to be ground, the motor 42 installed on the outer side of the side plate 2 drives the rotating shaft 4 to rotate, and the driving device 6 pushes the grinding components toward the hob 41, so that the cutting edge of the rotating hob 41 is located between the two wedge-shaped grinding stones 74 for grinding.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
