The working principle of the double-fork full-automatic bamboo chip sorting and binding machine of the embodiment is as follows.

(1) The bamboo strip grabbing and combining device starts to work as the first step: the stroke propulsion cylinder 11 starts to work, the propulsion cylinder mounting plate 14 and the two grabbing propulsion cylinders 10 move together along the guide rod 9 towards the bamboo chip collecting mechanism, when the grabbing propulsion cylinders 10 reach the upper part of the bamboo chip collecting mechanism, the grabbing propulsion cylinders 10 start to work, the push rod pushes the clamping cylinder 12 to move downwards, at the moment, the clamping jaws 13 on the clamping cylinder 12 are just located at the spaced neutral positions of the support rods 3 distributed at intervals in the bamboo chip collecting mechanism and are convenient to grab the bamboo chips 2 arranged on the support rods 3 in order, and the quantity of the clamping jaws 13 and the quantity of the bamboo chips 2 grabbed at one time can be adjusted according to the corresponding design in advance (for example, the quantity of the bamboo chips 2 grabbed at one time is 5, or 6, or 10). After the clamping jaws 13 grab the required bamboo chips 2 in the specified number, the push rods on the clamping cylinders 12 retract; after the bamboo splints are retracted to the designated position, the stroke propelling cylinder 11 continues to do a second stroke propelling action, the propelling cylinder mounting plate 14, the grabbing propelling cylinder 10, the clamping cylinder 12 and the clamped bamboo splints 2 move together to the upper space of the nearest U-shaped groove of the group of U-shaped forked seats 6, at the moment, the grabbing propelling cylinder 10 works, and the push rod is driven to drive the clamping cylinder 12 to approach the U-shaped groove of the U-shaped forked seat 6 of the forked sorting and pushing device; when the specified position is reached, the clamping jaws 13 are loosened, and the specified number of bamboo chips 2 just fall into the U-shaped groove of the U-shaped forked seat 6. At this moment, the stacking height of the bamboo chips 2 in the designated number is just slightly higher than the upper plane height of the U-shaped groove on the U-shaped forked seat 6, the micro-cylinder 7 arranged on the outer wall of the single-side U-shaped groove on the U-shaped forked seat 6 starts to work, the push rod is pushed to drive the pressing sheet 8 to press the side face of the stacking direction of the bamboo chips 2 in the designated number, and the bamboo chips 2 in the designated number are clamped in the U-shaped groove on the U-shaped forked seat 6. Then the clamping cylinder 12 of the clamping jaw 13 is released to retreat to the original position together with the grabbing and propelling cylinder 10 and the propelling cylinder mounting plate 14, the actions of grabbing the bamboo splints 2 are repeated, the bamboo splints move to the upper part of the second group of U-shaped forked bases 6 again, the specified number of bamboo splints 2 are repeatedly placed in the U-shaped grooves of the second group of U-shaped forked bases 6, and the pressing sheet 8 is pressed on the side surfaces of the specified number of bamboo splints 2 in the stacking direction after the micro-cylinder 7 works similarly (as shown in figure 2 a). The process completes the sorting procedure of a certain number of bamboo chips 2 which need to be bundled into a bundle, and replaces manual sorting.

(2) The turnover mechanism of the forked sorting and pushing device executes the working process: after the bamboo chips 2 with the specified number are clamped in the U-shaped grooves of the two groups of U-shaped forked seats 6, the rotary air cylinder 17 starts to work to drive the U-shaped forks of the two groups of U-shaped forked seats 6 to rotate 90 degrees towards the mouth-to-mouth direction, the process finishes face-to-face (or back-to-back) overturning and turning after the bamboo chips 2 are sorted in a classified mode, and manual overturning is replaced.

(3) As shown in fig. 5, the work flow is executed by the roller nip transmission mechanism of the forked sorting and pushing device: the first air cylinder 18 starts to work, and the roller pressure feeding transmission mechanism is arranged at the outer side of each group of U-shaped forked seats 6: the friction roller support 22, the friction roller 20 and the first motor 19 are driven to move towards the bamboo strip 2, when the sides of the friction rollers 20 distributed on the left side and the right side of the bamboo strip 2 lean against the overlapped sides of the bamboo strip 2, the first cylinder 18 stops propelling, at the moment, the micro cylinder 7 drives the pressing sheet 8 to do retraction motion, the first motor 19 starts to work, and the bamboo strip 2 moves towards the auxiliary roller conveying device under the action of the friction rollers 20.

(4) As shown in fig. 5, when one end of the bamboo strips 2 to be bundled approaches the auxiliary roller conveying device, one end of the bamboo strips 2 to be bundled passes through the lower end of the first upper pressing roller 23, and then continues to move under the action of the auxiliary roller conveying mechanism, when one end of the bamboo strips 2 just passes through a gap formed by compressing two side pressing rollers 25 in the auxiliary roller conveying device, the push rod of the second cylinder 26 starts to work to push the pressing roller 25, the side pressing roller support 27 and the second motor 28 to move together in the direction of the bamboo strips 2 to be bundled which are just conveyed and are stacked, and the side pressing roller 25 performs the next abutting stacking, at this time, the second motor 28 starts to work to continue to assist and drive the bamboo strips 2 to be bundled to move in the direction of the bundling machine 29 and pass through the 2 nd upper pressing roller 23.

(5) When the bamboo strips 2 to be bundled are pressed by the 2 nd upper press roll 23 to be conveyed out in an auxiliary manner, the automatic bundling of the bundling machine 29 starts, the head ends of the bamboo strips 2 to be bundled are automatically bundled firstly, then the automatic bundling is executed again after the bamboo strips 2 to be bundled are continuously conveyed for a distance, until the complete bamboo strips 2 to be bundled are bundled, and in the process, one ends of the bundled bamboo strips 2 are conveyed to the conveying belt 30 and finally conveyed to the unified collector.
