The present invention relates to the field of tableware processing, in particular, to a method and apparatus for processing bamboo tableware.
At present, the catering industry generally uses disposable tableware, in China, people usually use disposable bamboo chopsticks, bamboo is an environmentally friendly material and will not pollute the environment; however, in foreign countries, the disposable tableware used by people is mainly plastic knife, fork and spoon, because plastics is difficult to break down and easily pollute the environment, it is called “white pollution”; at the same time, as the “plastic ban” is gradually introduced in some countries and regions, the market of the plastic tableware is in a downturn, and more businesses have begun to use disposable bamboo tableware.
Because the shape and structure of knife, fork and spoon are completely different from the chopsticks, the process of processing knife, fork and spoon is also different from the chopsticks in the bamboo tableware processing industry. The current process of processing bamboo cutlery is as follows: the raw bamboo is made into bamboo strips, and the bamboo strips are made into rectangular bamboo chips, and then processed into bamboo tableware-shaped bamboo chips, finally, the fork and spoon-shaped bamboo chips are heat-pressed to form usable spoons and forks, and cut the blades of the knife-shaped bamboo chips diagonally to form the final bamboo knives.
In the process of processing rectangular bamboo chips into the shape of bamboo tableware, most prior art is stamping to process, and some are processed by milling cutter. For example, the application number: CN201610059496. 9 “The apparatus and producing process for industrial production of bamboo knife and spoon with moso bamboo chips”, which comprises a bamboo chip cutting machine, a bamboo knife, fork and spoon processing and polishing integrated machine, and a mold of one-time processing spoon with bamboo chip, among them, the bamboo knife, fork and spoon processing and polishing integrated machine can only process one rectangular bamboo chip into one bamboo tableware-shaped bamboo chip at one time, the processing efficiency is low, and the edge of the bamboo chip is prone to burrs after being cut by the milling cutter, which needs to be polished, there is a certain gap in the size of single product after polishing.
The purpose of the present invention is to overcome the above mentioned shortcomings of the prior art and provide a bamboo tableware processing method and apparatus for processing a plurality of bamboo chips without polishing at one time.
The technical solution of the present invention is as follow:
The present invention is bamboo tableware processing method and apparatus and comprising the following steps:
S1, using a clamping member (4) to clamp a plurality of bamboo chips;
S2, controlling a milling cutter (2) to rotate;
S3, moving the clamping member and/or the milling cutter to cut the plurality of bamboo chips by means of the milling cutter.
The above mentioned solution has the following advantages: a plurality of bamboo chips are clamped by the clamping member, when slowly passing the high-speed rotating milling cutter, the bamboo chips are cut by the milling cutter a little bit, and when one bamboo chip is processed by the milling cutter, due to the force, burrs will appear on the bamboo chips, but after a plurality of bamboo chips are clamped at the same time, the plurality of bamboo chips is restricted to each other due to the force, which is equivalent to forming a rectangular overall structure instead of one bamboo chip, therefore, no burrs will appear when processing a plurality of bamboo chips, which greatly saves the time for polishing and deburring; in this method, the clamping member can be moved and the milling cutter can be fixed; it can also be the milling cutter moved and the clamping part fixed; it can also be that the clamping member and the milling cutter move at the same time; preferably, the clamping member is moved and the milling cutter is fixed, because the milling cutter does not move, it is safer during processing.
Further, in S3, the cutting movement route of the bamboo chips is parallel to one of the tangent lines of the circle formed by the rotation of the milling cutter, and the distance from the tangent line remains unchanged. A plurality of bamboo chips are tangent to the outer circle formed by the rotation of the milling cutter, the edge of the bamboo chips is cut by the milling cutter, after cutting, the bamboo chips becomes tableware-shaped bamboo chips; when the milling cutter rotates, there will be countless tangent lines, the movement route of bamboo chips being parallel to any one of the tangent lines is to ensure that the bamboo chips can be moved along a straight line under the premise of cutting the bamboo chips by the milling cutter.
Further, the number of the plurality of bamboo chips is 20 to 200. Preferably, the number of the plurality of bamboo chips is 40 to 100; further preferably, the number of the plurality of bamboo chips is 60 to 80.
If there are less than 20 at one time, the production efficiency will be seriously affected; if more than 200, the clamping member can't hold the bamboo chips well, and the bamboo chips are likely to be scattered during processing; preferably, when processing 20 to 40 at one time, the processing efficiency is still relatively low; when 100 to 200, the bamboo chips may still be scattered during the processing; when the number of the bamboo chips is 60 to 80, the processing efficiency is appropriate, also there will be no scattered bamboo chips at the same time.
Further, in S1, it specifically comprising: immediately using a clamping member to clamp a plurality of bamboo chips; or placing defective replacement blocks between the plurality bamboo chips and the clamping members, and clamping a plurality of bamboo chips and defective replacement blocks by the clamping member.
After many times of processing, it is found that some of the bamboo chips are prone to be unqualified during processing, these unqualified bamboo chips are often the bamboo chips located at both ends, that is the bamboo chips close to the clamping members, this situation may be caused by the force and other reasons; therefore, defective replacement blocks are arranged at both ends, so that unqualified situation occurs on the defective replacement blocks, thereby improving the overall pass rate. The defective replacement blocks also need to be cut by the milling cutter, and the shape will be the same as the bamboo tableware, the material of the defective replacement blocks is preferably bamboo, wood or plastic, etc., such materials will not damage the milling cutter.
Further, in S2, during the rotation of the milling cutter, the position and angle of the milling cutter are selectively adjusted.
Further, adjusting the position of the milling cutter does not include the feeding direction of the multiple bamboo chips.
Further, the bamboo chips are vertically and flatly arranged between the clamping members, and the plurality of bamboo chips are cut along a straight line by milling cutters on both sides, and the plurality of bamboo chips are sequentially cut and processed into bamboo tableware-shaped at one time.
Further, it specifically comprises the following steps:
S101: setting the milling cutter inside of the cover of the bamboo shavings collecting apparatus (6), and the cutting part of the milling cutter extends from the cover;
S201: placing the plurality of bamboo chips between the clamping members (4) and clamping; or place defective replacement blocks on both ends of the plurality of bamboo chips, and clamp bamboo chips and defective replacement blocks by the clamping members (4);
S301: if the plurality of bamboo chips are not flat, performing a flattening step to ensure that the bamboo chips are flat; after flattening, the plurality of bamboo chips are further compressed;
S401: control the clamping member (4) or the milling cutter (2) to move slowly, so that the plurality of bamboo chips are cut along a straight line by the milling cutter, when cutting, one side of the plurality of bamboo chips is cut firstly, after cutting, then performing the cutting work on the other side; or both sides of the plurality of bamboo chips are cut at the same time to process at one time;
