DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to Figures 1 to 5 of the present invention, a double-roller nut peeling machine according to an embodiment of the present invention includes a frame 1, a casing 2, a feed hopper 3, an auxiliary feeding assembly 4, a peeling assembly 6 and a discharge port 7. The casing 2 is fixedly arranged on the frame 1, the feed hopper 3 is arranged at one end of the top of the casing and is connected thereto, the auxiliary feeding assembly 4 includes a speed regulating motor 41, a feed shaft 42 and a prying rod 43, the speed regulating motor 41 is fixedly installed on the frame 1, the feed shaft 42 is rotatably connected in the feed hopper 3 and is drivingly connected to the output shaft of the speed regulating motor 41; the prying rod 43 is annularly fixed on the feed shaft 42; the peeling assembly 6 It includes a peeling motor 61, a plurality of peeling rollers 62 arranged in parallel and a pressing device 63. The peeling motor 61 is fixed on the frame 1 and is connected to the peeling rollers 62 in transmission. The peeling rollers 62 are connected in pairs in the casing 2 and the two peeling rollers in the group rotate in corresponding directions of mutual extrusion. The pressing device 63 is arranged at the middle top of the two peeling rollers in the group and is fixedly connected to the frame 1. The material removing rod 43 is located at the middle upper position of the two peeling rollers 62 near one end thereof. The peeling port 5 is arranged at the bottom of the casing 2, and the discharge port 7 is arranged at the bottom of the other end of the casing 2 and corresponds to one end of the peeling roller.

Specifically, the material shifting direction of the material shifting rod is the same as the material feeding direction.

In some specific embodiments, the peeling roller 62 is provided with a feeding thread 621, a notching spiral blade 622 and an extrusion thread 623 in sequence from one end to the other end. The feeding threads 621, the notching spiral blade 622 and the extrusion threads 623 on the two peeling rollers 62 in a group have opposite spiral directions to ensure the orderly advancement of the material.

In other embodiments, the pitch of the feed thread 621 is equal to the pitch of the extrusion thread 623, so that the feed speed is equal to the discharge speed.

Specifically, the pitch of the notching spiral blade 622 is 10 mm.

In some other specific embodiments, the feeding threads 621 and the extrusion threads 623 on the two peeling rollers 62 arranged in a group are alternately and staggeredly distributed along the axial direction of the peeling rollers.

In some other embodiments, the pressing device 63 includes a first pressing block 631 and a second pressing block 632. The first pressing block 631 is arranged on a frame close to the side of the feed hopper and is located in the middle and upper position of the two peeling rollers; the second pressing block 632 is a chain-type pressing block, which is fixedly connected to the frame, and its length direction is arranged along the axial direction of the peeling roller 62 and is located in the middle and upper position of the two peeling rollers 62 in a group. The second pressing block 632 is located on one side of the discharge direction of the first pressing block 631. The nuts are peeled under the cooperation of the peeling roller, the first pressing block and the second pressing block, and the rolling action of the peeling roller reduces the impact on the nuts, and the damage rate is reduced.

Specifically, the chain-type pressing block is tiltedly arranged on the frame 1, and the chain-type pressing block is tilted downwardly corresponding to the discharge direction, so as to improve the removal rate of the material at the outlet.

More specifically, the first pressure block and the second pressure block are both fixedly connected to the frame through a bracket, and the compression degree of the first pressure block and the second pressure block are adjusted by a screw rod, a compression spring is passed through the screw rod, and the two ends of the compression spring are respectively fixedly connected to the screw rod and the first pressure block and the second pressure block, and the compression degree of the first pressure block and the second pressure block is adjusted by the screw rod as a whole. The setting of the spring allows the first pressure block and the second pressure block to float up and down at a certain distance, thereby reducing the bad fruit rate and facilitating the resetting of the first pressure block and the second pressure block.

In some other specific embodiments, the bottom of the chain-type pressing block is alternately fixed with extrusion blocks 8 providing vertical extrusion force and extrusion bars 9 providing horizontal extrusion force along its length direction; the extrusion block 8 is hemispherical, and the extrusion bar 9 is parallel to the axial direction of the peeling roller 62. Under the premise of the rotation of the peeling roller, the nuts are driven to move toward the discharge port. The set pressing blocks and pressing bars alternately press the nuts, so that the nuts can effectively contact the peeling roller and be peeled, thereby further improving the peeling rate.

Specifically, the two peeling rollers 62 in a group and the pressing device 63 arranged at the top in the middle thereof form a triangular feeding channel, which gradually decreases in the direction of discharging, and the maximum size of the inscribed circle of the feeding channel is 40 mm and the minimum is 28 mm. This avoids blockage of multiple nuts, and the discharging port can squeeze the smallest fruit, thereby improving the peeling rate.

More specifically, the peeling rollers are grouped in pairs and connected via gear transmission to change the rotation direction of the peeling rollers.

More specifically, the device of the present invention can be applied to connect other driving devices on a production line to provide a power source for them.

The peeling steps of a double-roller nut peeling machine of the present invention are as follows:

The nut peeling process is divided into four stages: feeding, notching to pre-treat the green peel, squeezing the green peel, and separating the peel and fruit. The material is fed from the hopper, and with the assistance of the speed regulating motor and the material-shifting rod, the material enters the gap between the two rollers rotating in groups in an orderly manner, and is pushed to the notching spiral blade part by the feeding thread. The notching pre-treating green peel uses a notching spiral blade to destroy the integrity of the green peel, which can reduce the squeezing force when squeezing the green peel, and then enters the squeezing thread section and the briquetting device to squeeze and peel. The peeled nuts are received at the discharge port, and the green peel is collected at the peeling port, giving full play to the advantages of the chain-type briquetting, without reducing production efficiency at the cost of improving the peeling rate and reducing the breakage rate.

The specific speed regulating motor can adjust the speed of the feed shaft, thereby affecting the feeding effect. The group of peeling rollers and the briquetting device can form a feeding channel, and the material is peeled in the feeding channel. The present invention is easy to operate, has a high degree of automation, and can maintain a high peeling rate and a high integrity rate of nuts.

As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
