Description

Chopstick trimming equipment

Technical Field

The invention relates to the field of chopstick manufacturing, in particular to chopstick trimming equipment.

Background

The grinding equipment in the existing production equipment for molded resin or molded plant fiber chopsticks is a chopstick grinding machine which is structurally characterized in that four pairs of pressing wheels are used for feeding materials, grinding wheels fixedly arranged on one side form a unit for grinding, and two units form grinding equipment on two sides. When the mold clamping lines of the chopsticks are polished, burrs at two sides formed by the mold clamping lines on the chopsticks are polished and polished by feeding with a pressing wheel and trimming with a grinding wheel. In the process of polishing the chopsticks, the chopsticks are transferred and conveyed between the pressing wheels to do linear motion by taking the center line of the chopsticks as the reference. In the chopstick transferring process, when the grinding wheel is used for grinding, the cylindrical part of the chopstick is transited to the square column part, so that the purpose of deburring the bevel edge cannot be achieved. Therefore, the distance between the pressing wheels is larger, and the purpose of polishing the bevel edge is achieved by natural bending of the length of the chopsticks due to the reverse extrusion force generated when the grinding wheel contacts the polished surface of the chopsticks. The technological requirement of burr polishing can be met only when the abrasion resistance strength of the chopsticks is less than the reverse extrusion force of the grinding wheel by taking the length of the chopsticks as a reference during the distance between the pressing wheels. The spacing of the pressing wheels must be greater than one-half of the chopsticks. When the head end of the chopstick does not enter the front pressing wheel, the tail end of the chopstick is separated from the pressing wheel. When the chopsticks are moved forward, the center is unstable, the trimmed edge is irregular, the rough edge cannot be completely removed, the linearity of the trimmed side edge is poor, and the technical conditions of the product cannot be met.

The prior utility model patent discloses, the publication number is: CN201012466Y published date is: 2008-01-30: the chopstick grinding machine comprises a plurality of feeding pressing wheels and a grinding wheel, wherein the feeding pressing wheels and the grinding wheel are used for grinding chopsticks, an operator finds that the grinding has some problems, the grinding wheel is fast worn in the using process, the working temperature is high, the correction surface is rough and not attractive, the noise is large during working, the grinding wheel is used for grinding dust, the grinding dust flies upwards along with the rotation of the grinding wheel, meanwhile, the function of the device is single, and the width of the aimed chopsticks is very limited.
