Description

TECHNICAL FIELD

Nut breaking technology is a worldwide research topic. Currently, the extrusion breaking process is used in the production and processing of walnuts and beignuts, which is the most common and advanced breaking process in the world.

[0003] The extrusion breaking process has the following defects: because nuts are agricultural products and need to be produced on a large scale, it is impossible to ensure that the size and shape of the nuts are the same, even if screening is used, it can only be controlled within a certain specification, and it is impossible to ensure that every nut has a crack during the extrusion process (due to the uneven size and irregular shape of the nuts), and the cracks are of different sizes, irregular or uneven, resulting in a high breakage rate. For baked shelled nuts to taste: the cracks are of different sizes, irregular, uneven, and it is impossible to ensure that every nut has a crack, which makes it difficult to break by hand, difficult to remove the shell, and affects the consumer's eating; a small amount of water enters or excess water shakes out during the processing of the cooked product, resulting in uneven taste, nut kernels that are not crisp, and kernel clothes that are not easy to remove during eating, resulting in a bitter taste, affecting eating and consumer experience, and affecting sales; the breakage rate is high during large-scale processing, and a large amount of broken powder is produced at the bottom of the packaging bag after packaging, which is not aesthetic, resulting in the inability to use an automatic packaging machine for packaging, and only manual packaging, which is not sanitary, has low production efficiency, and increases production costs and other unfavorable factors.

[0042] In order to ensure that the clamping jaw 133 effectively clamps the nuts, and avoid damaging the nuts, in the embodiment, as shown in Figure 5 and Figure 6As shown, the clamping structure 13 further comprises a mounting frame 134 fixedly arranged on the rotating disc 124, and the movable plate 131 is slidably connected with the mounting frame 134 through a linear guide rail 135; further, in the embodiment, the first clamping block 1331 and the second clamping block 1332 are both made of elastic material, and the working surfaces of the first clamping block 1331 and the second clamping block 1332 corresponding to each other are both in a wavy shape, and the first clamping block 1331 and the second clamping block 1332 can be made into profiled blocks, and corresponding clamping jaws 133 can be replaced according to different nuts.

[0043] In order to effectively prevent nuts from flying out of the clamping jaw 133, in the embodiment, as shown in Figure 3 、 Figure 4 and Figure 8 , the cutting mechanism 1 further comprises an annular baffle 15, and the annular baffle 15 of the embodiment is in a semi-circular ring split type, the annular baffle 15 is covered on the outer periphery of the rotating disc 124, the clamping structure 13 is located between the annular baffle 15 and the rotating disc 124, a feeding port 151 is arranged on the annular baffle 15 at the feeding station 4, a cutter port 152 is arranged on the annular baffle 15 at the cutting station 5, and a discharging port 153 is arranged on the annular baffle 15 at the discharging station 6; further, in the embodiment, a discharging bin 2 is arranged at the discharging port 153, and the discharging bin 2 is used for leading out nuts that have been cut, facilitating the discharging of nuts that have been cut, and effectively preventing nuts from being squeezed and damaged during discharging.

[0044] In order to facilitate automatic feeding, in the embodiment, as shown in Figure 9 and Figure 10As shown, the feeding station 4 is provided with a feeding mechanism 3, which is located at the side of the turntable 124. The feeding mechanism 3 comprises a base 31, a hopper 32 and a conveying belt structure 33. The conveying belt structure 33 comprises a belt driving assembly 331 and upper and lower annular belts 332 and 333.

The hopper 32 is arranged on the base 31. In this embodiment, a vibrating member 34 is arranged on the hopper 32 to facilitate the vibrating of nuts. The discharge opening of the hopper 32 is in communication with the input opening of the conveying channel 334. The output opening of the conveying channel 334 faces the clamping jaw 133 at the feeding station 4. When the nuts enter the conveying channel 334 from the hopper 32, the upper and lower annular belts 332 and 333 clamp the nuts and convey the nuts to the clamping jaw 133 at the feeding station 4. Since the upper and lower annular belts 332 and 333 have a certain elasticity, the nuts can be effectively clamped without being damaged.

[0045] The working principle is as follows:

[0046] Firstly, the nuts to be cut, such as walnuts or pecans, are poured into the hopper 32. The nuts fall from the discharge opening of the hopper 32 to the input opening of the conveying channel 334 and automatically fall into the corresponding grooves 3331. Under the conveying action of the upper and lower annular belts 332 and 333, the nuts are conveyed to the clamping jaw 133 at the feeding station 4. At this time, the clamping jaw 133 clamps the nuts. The nuts are conveyed to the cutting station 5 along with the turntable 124. At this time, the cutter 141 cuts along the width direction of the nuts until two cuts are formed along the length direction of the nuts. Figure 11 As shown, the cut nuts are conveyed to the discharging station 6 along with the turntable 124. At this time, the clamping jaw 133 is opened. The nuts enter the discharging bin 2 under the action of centrifugal force. The working processes of the four flow lines on the turntable 124 are consistent and performed simultaneously.

[0047] Wherein, the belt driving assembly 331 drives the upper annular belt 332 and the lower annular belt 333, realizes the upper annular belt 332 and the lower annular belt 333 conveying nuts, simultaneously, the first motor 121 starts, drives the gear set 123, the hollow shaft 122 and the rotating disc 124 rotates in turn, simultaneously, the clamping structure 13 rotates with the rotating disc 124, the cam roller 132 of the clamping structure 13 is limited under the phase trajectory groove 1251, drives the movable plate 131 to move, to realize the first clamping block 1331 close to or away from the second clamping block 1332, namely realizes the clamping jaw 133 clamping and loosening, the clamping jaw 133 is in the loosened state before the loading station 4, the clamping jaw 133 clamps the nut when the loading station 4, until the nut is carried to the notch station 5, when the clamping jaw 133 carries the nut and leaves the notch station 5 to reach the unloading station 6, the clamping jaw 133 loosens and releases the nut to the unloading bin 2.
