Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sponge processing equipment, and relates to a sponge cutting knife belt assembly. Background Art
[0002] During the process of cutting seven sponges with a circular toothed sponge cutting knife belt, chips are easily generated. Especially when cutting hard sponges added with calcium carbonate, the generation of chips not only affects the quality of the sponge, but also easily generates flue gas at high temperatures, affecting the color of the sponge and the workshop environment. In addition, the grinding device of the circular knife belt is also prone to generate flue gas and dust. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a sponge cutting knife belt assembly for the above-mentioned problems existing in the current technology. The technical problem to be solved by the utility model is how to prevent the flue gas and dust generated during cutting from affecting the product quality.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A sponge cutting knife belt assembly, characterized in that it includes a flat smoke collecting hood. At both ends of the entrance of the smoke collecting hood, a driving wheel is respectively rotatably connected. A cutting knife belt is pulled between the two driving wheels. The top of the smoke collecting hood has a connecting pipe, and the connecting pipe is connected to a negative pressure air source.
[0005] Further, a swing arm is rotatably connected inside the smoke collecting hood. The middle part of the swing arm is hinged to the wall plate of the smoke collecting hood. A tension spring is connected between one end of the swing arm and the wall plate of the smoke collecting hood. A grinding block is fixedly arranged at the other end of the swing arm.
[0006] Further, the cutting knife belt includes a cutting straight section below the opening of the smoke collecting hood and a grinding straight section inside the smoke collecting hood, and the grinding block abuts against the grinding straight section.
[0007] In this solution, the grinding position is completely set inside the smoke collecting hood. The flue gas and chips generated during the grinding of the knife belt can be timely evacuated, avoiding secondary damage to the cutting knife belt, and effectively protecting the sponge from pollution. In addition, the flue gas and chips generated during the cutting process can also be evacuated to a certain extent. During this process, the heat generated by the cutting knife belt during the cutting of hard sponges and the grinding process can also be effectively evacuated, reducing the temperature of the cutting knife belt and improving the cutting accuracy. Brief Description of the Drawings
[0008] Figure 1 is a schematic structural diagram of the sponge cutting knife belt assembly.
[0009] Figure 2 is a schematic internal structure diagram of the sponge cutting knife belt assembly.
[0010] In the figure, 1 is a smoke collecting hood; 2 is a driving wheel; 3 is a cutting knife belt; 4 is a swing arm; 5 is a tension spring; 6 is a knife sharpening block. Detailed implementation mode
[0011] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0012] As Figure 1 and Figure 2 shown in the sponge cutting knife belt assembly, which includes a flat smoke collecting hood (1), at both ends of the entrance of the smoke collecting hood (1) are respectively rotatably connected with a driving wheel (2), a cutting knife belt (3) is pulled between the two driving wheels (2), the top of the smoke collecting hood (1) has a connecting pipe, and the connecting pipe is connected to a negative pressure air source.
[0013] A swing arm (4) is rotatably connected inside the smoke collecting hood (1), the middle part of the swing arm (4) is hinged to the wall plate of the smoke collecting hood (1), a tension spring (5) is connected between one end of the swing arm (4) and the wall plate of the smoke collecting hood (1), and a knife sharpening block (6) is fixedly arranged at the other end of the swing arm (4).
[0014] The cutting knife belt (3) includes a cutting straight section below the opening of the smoke collecting hood (1) and a grinding straight section inside the smoke collecting hood (1), and the knife sharpening block (6) abuts against the grinding straight section.
[0015] In this solution, the grinding position is completely set inside the smoke collecting hood (1), and the smoke and debris generated by the grinding knife belt can be timely evacuated, avoiding secondary damage to the cutting knife belt (3), and effectively protecting the sponge from pollution. In addition, the smoke and debris generated during the cutting process can also be evacuated to a certain extent. During this process, the heat generated by the cutting knife belt (3) during the cutting of hard sponge and the grinding process can also be effectively evacuated, reducing the temperature of the cutting knife belt (3) and improving the cutting accuracy.
[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
