Operation principle: first the bamboo chip processed is put into bamboo chip case 9, then wear bamboo chip needlework 1 to penetrate first wear in bamboo chip pin 5 pin hole by first, and have knotting, then wear bamboo chip pin 5 left side by first and put into the first bamboo chip pin trapezoidal folder 3 lower end and the clamping of the 3rd bamboo chip pin trapezoidal folder 13 upper end, then wear first and on the right of bamboo chip pin 5, to put into the second bamboo chip pin trapezoidal folder 6 lower end and the clamping of the 4th bamboo chip pin trapezoidal folder 15 upper end.Wear again bamboo chip needlework 19 to penetrate second wear in bamboo chip pin 25 pin hole by second, and have knotting, then wear bamboo chip pin 25 left side by second and put into the 5th bamboo chip pin trapezoidal folder 26 lower end and the clamping of the 7th bamboo chip pin trapezoidal folder 60 upper end, then wear second on the right of bamboo chip pin 25 and put into the 6th bamboo chip pin trapezoidal folder 48 lower end and the clamping of the 8th bamboo chip pin trapezoidal folder 58 upper end.Wear bamboo chip needlework 20 again to penetrate the 3rd wear in bamboo chip pin 21 pin hole by the 3rd, and have knotting, then wear bamboo chip pin 21 left side by the 3rd and put into the 9th bamboo chip pin trapezoidal folder 22 lower end and the clamping of the 11 bamboo chip pin trapezoidal folder 64 upper end, then wear the 3rd and on the right of bamboo chip pin 21, to put into the tenth bamboo chip pin trapezoidal folder 27 lower end and the clamping of the 12 bamboo chip pin trapezoidal folder 63 upper end.Immediately when motor 38 axis of rotation, namely drive the first belt pulley 37, first belt 36, second belt pulley 35, first Pulley shaft 42, 3rd belt pulley 43, second belt 34, 4th belt pulley 33, second Pulley shaft 41, driving lever 32, shift lever axis 31, connecting rod 40, pitman shaft 30, first clamping plate 39, second clamping plate 45, top board 11, first push rod 10 and the second push rod 28 are to left movement, and now the first push rod 10 left end promotes on the right of bamboo chip 2 bottom, and the second push rod 28 left end promotes bamboo chip 2 top right simultaneously, when bamboo chip 2 is pushed into the trapezoidal folder 6 of the second bamboo chip pin, the trapezoidal folder 15 of 4th bamboo chip pin, the trapezoidal folder 48 of 6th bamboo chip pin, the trapezoidal folder 58 of 8th bamboo chip pin, during trapezoidal folder 63 right-hand member of the tenth bamboo chip pin trapezoidal folder the 27 and the 12 bamboo chip pin, bamboo chip 2 continues propelling makes the trapezoidal folder 6 of the second bamboo chip pin, the trapezoidal folder 15 of 4th bamboo chip pin, the trapezoidal folder 48 of 6th bamboo chip pin, the trapezoidal folder 58 of 8th bamboo chip pin, the trapezoidal folder 63 of tenth bamboo chip pin trapezoidal folder the 27 and the 12 bamboo chip pin respectively under the action of the spring upwards, lower separately, bamboo chip 2 is by after above-mentioned folder, and first wears on the right of bamboo chip pin 5 and penetrated the first bamboo chip hole 56, second wears on the right of bamboo chip pin 25 and has penetrated the second bamboo chip hole 55, 3rd wears on the right of bamboo chip pin 21 and has penetrated the 3rd bamboo chip hole 54, immediately moment the second bamboo chip pin trapezoidal folder 6 lower end and the 4th bamboo chip pin trapezoidal folder 15 upper end clamping first wear on the right of bamboo chip pin 5, 6th bamboo chip pin trapezoidal folder 48 lower end and the 8th bamboo chip pin trapezoidal folder 58 upper end clamping second are worn on the right of bamboo chip pin 25, tenth bamboo chip pin trapezoidal folder 27 lower end and the 12 bamboo chip pin trapezoidal folder 63 upper end clamping the 3rd are worn on the right of bamboo chip pin 21.When bamboo chip 2 is pushed into the trapezoidal folder 3 of the first bamboo chip pin, the trapezoidal folder 13 of 3rd bamboo chip pin, the trapezoidal folder 26 of 5th bamboo chip pin, the trapezoidal folder 60 of 7th bamboo chip pin, the trapezoidal folder 22 of 9th bamboo chip pin, during the 11 trapezoidal folder 64 right-hand member of bamboo chip pin, bamboo chip 2 continues propelling makes the trapezoidal folder 3 of the first bamboo chip pin, the trapezoidal folder 13 of 3rd bamboo chip pin, the trapezoidal folder 26 of 5th bamboo chip pin, the trapezoidal folder 60 of 7th bamboo chip pin, the trapezoidal folder 22 of 9th bamboo chip pin, the trapezoidal folder 64 of 11 bamboo chip pin respectively under the action of the spring upwards, separately lower, bamboo chip 2 is by after rear above-mentioned folder, the trapezoidal folder of moment the first bamboo chip pin 3 and the trapezoidal folder 13 of the 3rd bamboo chip pin clamp first and wear bamboo chip pin 5 left side immediately, the trapezoidal folder of 5th bamboo chip pin 26 and the trapezoidal folder 60 of the 7th bamboo chip pin clamp second and wear bamboo chip pin 25 left side, the trapezoidal folder 64 of 9th bamboo chip pin trapezoidal folder the 22 and the 11 bamboo chip pin clamps the 3rd and wears bamboo chip pin 21 left side, now namely bamboo chip 2 is put on.Then when motor 38 rotating shaft is rotated further, namely drive the first belt pulley 37, first belt 36, second belt pulley 35, first Pulley shaft 42, the 3rd belt pulley 43, second belt 34, the 4th belt pulley 33, second Pulley shaft 41, driving lever 32, shift lever axis 31, connecting rod 40, pitman shaft 30, first clamping plate 39, second clamping plate 45, top board 11, first push rod 10 and the second push rod 28 to move right and make the first push rod 10, second push rod 28 left end lean on right side to bamboo chip case 9 respectively, the bamboo chip of last layer automatically falls under the gravity of self.Motor 38 remains in operation and repeats above-mentioned action.The bamboo chip block put on according to people's requirement, can be got its length and is sheared by bamboo chip needlework respectively, and namely had knotting by the needlework at bamboo chip block two be respectively the bamboo mat (or bamboo chip cushion block) put on.

Feature of the present utility model changes into machinery wear bamboo chip from manually wearing bamboo chip, improves bamboo chip and to thread a needle speed, alleviate the labour intensity of people preferably, and can greatly increase work efficiency.The automatic needle-threading machine of this bamboo chip is of many uses, and is that structure is simple, and Neng Shi manufacturer easily manufactures.
