Description

Technical Field

[0001] The utility model relates to the field of flame retardant material production and processing, in particular to a flame retardant material cutting device with a blowing function. Background Art

[0002] Flame retardant material cutting refers to the process of processing flame retardant materials into small pieces of materials of required size and shape. The cut flame retardant materials are usually used for mixing and preparing composite materials, and added to plastics or rubber to increase their flame retardant properties. When performing specific operations, the flame retardant materials are generally prepared first, and then the raw materials are cut into the required size and shape using a cutting machine. During the cutting process, the raw materials are usually directly transported. However, this method lacks positioning of the raw materials, and the traction force generated during the cutting process will cause the position of the raw materials to shift, thereby affecting the final cutting effect. In addition, the cut flame retardant materials will accumulate due to falling, and will aggregate into clumps during the discharging process, making it inconvenient for operators to screen the materials.

[0003] Therefore, in order to solve the above problems, a flame retardant material cutting device with a blowing function is developed to limit the feeding position of the material and avoid position deviation during the cutting process. Utility Model Content

[0004] In order to overcome the shortcomings that the existing devices lack a limit on the position of the raw materials, the traction force generated during the cutting process will cause the position of the raw materials to shift, thereby affecting the final cutting effect, and the flame retardant materials after cutting will accumulate due to falling and gather into clumps during the discharging process, making it inconvenient for operators to screen the materials. The utility model provides a flame retardant material cutting device with a blowing function, which can limit the feed of the material and avoid position shift during the cutting process.

[0005] The technical solution of the utility model is: a flame retardant material cutting device with a blowing function, comprising a base, a pelletizing chamber is installed on the top of the base, a servo motor is installed on the upper right side of the base through bolts, a guide knurled shaft is rotatably arranged at the front of the pelletizing chamber, the right end of the guide knurled shaft is through-connected to the right side wall of the pelletizing chamber, the right end of the guide knurled shaft is connected to the output shaft of the servo motor, a cutting wheel is rotatably arranged at the rear of the pelletizing chamber, the right end of the cutting wheel is through-connected to the right side wall of the pelletizing chamber, a transmission gear set is connected between the right end of the cutting wheel and the output shaft of the servo motor, and two left-right symmetrical fans are connected to the front side of the lower part of the pelletizing chamber.

[0006] As a further preferred embodiment, a protective cover is also included, which is rotatably arranged on the upper part of the pelletizing chamber, and the upper part of the protective cover is provided with a transparent observation window. Two left-right symmetrical guide blocks are connected to the lower front side of the protective cover, and limiting rollers are slidably and rotatably arranged between the guide blocks, and return springs are connected between the left and right ends of the limiting rollers and the corresponding guide blocks.

[0007] As a further preferred scheme, it also includes a guide groove plate, which is sleeved on the rear part of the pelletizing chamber, and the rear and lower sides of the guide groove plate are connected with screens for preliminary screening of the flame retardant material after cutting, and the upper front side of the guide groove plate is connected with a guide column, and a sliding block is slidably connected to the guide column, and a limiting spring is connected between the sliding block and the guide column, and a positioning pin is connected to the upper rear side of the pelletizing chamber, and the positioning pin is clamped with the sliding block.

[0008] As a further preferred solution, a limiting groove is provided at the rear of the base, and the limiting groove is used for positioning the container.

[0009] As a further preferred solution, the blades on the cutting wheel are all inclined structures.

[0010] As a further preferred solution, the transmission gear set is composed of a small spur gear and a large spur gear, forming different speed combinations.

[0011] By adopting the above technical solution, the utility model has the following advantages:

[0012] 1. When the flame retardant material is cut, the utility model utilizes the differential speed of the transmission gear set to enable the flame retardant material to be pelletized during the rapid feeding process, and in this process, the limiting is achieved by the cooperation and compression of the guide knurled shaft and the limiting roller, so as to avoid the extra traction force generated when the cutting wheel cuts the flame retardant material, causing accidental displacement and affecting the cutting effect. After the cutting is completed, the flame retardant material falls into the pelletizing chamber, and under the blowing action of the airflow generated by the fan, the material can be quickly dispersed and discharged, so as to prevent the material from agglomerating and affecting the material collection.

[0013] 2. The utility model performs preliminary screening of the flame retardant materials after cutting through the screen on the guide groove plate. After the screening is completed, the sliding block is pushed upward to compress the limit spring. At the same time, the sliding block is disengaged from the positioning pin. At this time, the guide groove plate is pulled backward and disengaged from the pelletizing cavity. Finally, the material in the guide groove plate is poured out, thereby realizing preliminary screening and rapid collection of the flame retardant materials after cutting, and improving the convenience of operation.

It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0020] Example 1

[0021] A flame retardant material cutting device with a blowing function, such as Figure 1-Figure 3 As shown, it includes a base 1, a limiting groove is opened at the rear of the base 1, and the limiting groove is used to position the container. A pelletizing chamber 2 is installed on the top of the base 1, and a servo motor 3 is installed on the upper right side of the base 1 through bolts. The output shaft of the servo motor 3 is set to the left. A guide knurled shaft 4 for frictionally guiding the flame retardant material is rotatably arranged at the front of the pelletizing chamber 2, and the right end of the guide knurled shaft 4 is connected to the right side wall of the pelletizing chamber 2 in a through-type connection, and the right end of the guide knurled shaft 4 is connected to the output shaft of the servo motor 3. A cutting wheel 6 is rotatably arranged at the rear of the pelletizing chamber 2, and the blades on the cutting wheel 6 are all inclined structures. The right end of the cutting wheel 6 is connected to the right side wall of the pelletizing chamber 2 in a through-type connection, and a transmission gear set 5 is connected between the right end of the cutting wheel 6 and the output shaft of the servo motor 3. The transmission gear set 5 is composed of a small spur gear and a large spur gear to form different speed combinations. Two left-right symmetrical fans 11 are connected to the front side of the lower part of the pelletizing chamber 2, and the fans 11 are used to generate airflow to blow away the pelletized flame retardant material.

[0022] like Figure 1As shown, it also includes a protective cover 7, which is rotatably arranged on the upper part of the pelletizing chamber 2. The upper part of the protective cover 7 is provided with a transparent observation window. Two left-right symmetrical guide blocks 8 are connected to the lower front side of the protective cover 7. A limiting roller 10 for cooperating with the guide knurled shaft 4 to press and limit the flame retardant material is slidably and rotatably arranged between the guide blocks 8. Reset springs 9 are connected between the left and right ends of the limiting roller 10 and the corresponding guide blocks 8.

[0023] It should be noted that when the flame retardant material has been cooled, the formed flame retardant material is fed into the pelletizing chamber 2 for cutting. When feeding the flame retardant material, it is necessary to place it on the upper side of the guide knurled shaft 4 and fit it, and then allow the flame retardant material to pass through the lower side of the cutting wheel 6 to enter the pelletizing chamber 2, and then press the protective cover 7 downward so that the limiting roller 10 can cooperate with the guide knurled shaft 4 to form a two-way compression of the flame retardant material. In the process of the limiting roller 10 compressing the flame retardant material, the reset spring 9 will be compressed due to the force, so as to avoid the additional traction generated by the cutting wheel 6 when cutting the flame retardant material. Unexpected displacement affects the cutting effect. After the flame retardant material is compacted, the servo motor 3 and the fan 11 are started. The rotation of the output shaft of the servo motor 3 will drive the transmission gear set 5 to operate, so that the guide knurled shaft 4 starts to rotate rapidly, and cooperates with the limiting roller 10 to feed the flame retardant material. At the same time, the cutting wheel 6 will also start to rotate slowly, and pelletize the flame retardant material during the rotation process. After cutting, the flame retardant material will fall into the lower part of the pelletizing chamber 2. At this time, under the action of the fan 11, the airflow generated will blow the cut flame retardant material, so that the cut flame retardant material can be dispersed and discharged to avoid the material from agglomerating.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1-Figure 4 As shown, it also includes a guide groove plate 12, which is sleeved on the rear part of the pelletizing chamber 2. The rear and lower sides of the guide groove plate 12 are connected with screens for preliminary screening of the flame retardant material after cutting. A guide column 13 is connected to the upper front side of the guide groove plate 12, and a sliding block 15 is slidably connected to the guide column 13. A limiting spring 14 is connected between the sliding block 15 and the guide column 13. A positioning pin 16 is connected to the upper rear side of the pelletizing chamber 2, and the positioning pin 16 is clamped with the sliding block 15.

[0026] It should be noted that the flame retardant material after cutting will disperse and move backward under the action of the fan 11, and finally move to the inside of the guide groove plate 12, and rely on the screen on the guide groove plate 12 to perform preliminary screening on the flame retardant material after cutting. After the screening is completed, the sliding block 15 is pushed upward to compress the limit spring 14, and at the same time, the sliding block 15 is disengaged from the positioning pin 16. At this time, the guide groove plate 12 is pulled backward and disengaged from the pelletizing chamber 2, and finally the material in the guide groove plate 12 can be poured out.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
