[0032] The chestnut de-flaking and packaging system proposed by the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0033] Chestnut deflating and packaging system includes:

[0034] A deflating device 100, a conveying device 200, a packaging device 300 and a controller 400;

[0035] Please refer to Figures 1 to 3As shown, the conveying device 200 and the packaging device 300 are arranged along the length direction of the system, and the deflating device 100 and the packaging device 300 are arranged along the width direction of the system, so that the entire system is L-shaped.

[0036] The de-flaking device 100 includes a de-flaking component 110, a feeding component 120 and a discharging component 130; the feeding component 120 is used to convey the chestnuts to be de-flaked into the de-flaking component 110, the de-flaking component 110 is used to de-flake the chestnuts to be de-flaked and separate the detached chestnut fluff and fruit particles, and the discharging component 130 is used to convey the fruit particles.

[0037] Please continue to refer to Figures 1 to 3 As shown, the feed assembly 120 and the discharge assembly 130 are screw conveyors, which include a conveying pipe and a screw conveying blade coaxially built into the conveying pipe, and the screw conveying blade is driven to rotate by an external motor. In this embodiment, the feed assembly 120 and the discharge assembly 130 are respectively arranged on two adjacent sides of the de-hair removal device 100. In other alternative embodiments, the feed assembly 120 and the discharge assembly 130 can be arranged on two opposite sides of the de-hair removal device 100.

[0038] Please continue to refer to Figure 1 As shown, the chestnut de-flaking and packaging system further includes a fruit bucket 114, a chestnut fluff bucket 117 and a feed hopper 118, and the inlet of the feed assembly 120 is communicated with the inner cavity of the feed hopper 117. The chestnut fluff bucket 117 and the feed hopper 118 are respectively located on opposite sides of the de-flaking assembly 110. The chestnut fluff after de-flaking by the de-flaking assembly 110 falls into the chestnut fluff bucket 117 and is collected, and the fruit particles fall into the fruit particle bucket 114 and are collected. The inlet of the discharging assembly 130 is communicated with the inner cavity of the fruit particle bucket 114, and is used to transport and collect the fruit particles in the fruit particle bucket 114.

[0039] The packaging device 300 includes a packaging platform 310 and a weighing device 320. The packaging platform 310 is used to place the packaging box 500. The outlet of the discharging component 130 is located directly above the packaging platform 310. The discharging component 130 transports the fruit particles and makes the fruit particles fall into the packaging box 500 through its outlet. The weighing device 320 is arranged on the packaging platform 310 to weigh the packaging box 500.

[0040] In this embodiment, the packaging platform 310 is a belt conveyor, which preferably adopts flat belt conveyor. The belt conveyor is horizontally docked with the conveying device 200, so when the packaging platform 310 is started, the packaging box 500 can be transferred to the conveying device 200. In other alternative embodiments, a part of the conveying device 200 can be used as the packaging platform 310, in which case, only the conveying device 200 needs to be started to transport the packaging box 500 without transfer.

[0041] The weighing device 320 may use existing equipment, such as a floor scale, which is set between the upper and lower belts of the belt conveyor; or the weighing device 320 may be homemade, such as by setting a weighing platform between the two rollers of the belt conveyor, and setting a pressure sensor on the weighing platform, so that the pressure is converted into weight information through the pressure sensor; in this embodiment, the packing box 500 is a rectangular parallelepiped, and the upper end of the packing box 500 is open.

[0042] The conveying device 200 is used to convey the packaging box 500 filled with fruit particles to a designated location. In this embodiment, the conveying device 200 is a roller conveyor, which includes a conveying frame 210, conveying rollers 220 arranged along the length direction of the system, and a transmission system for driving the conveying rollers 220 to rotate. The roller conveyor is an existing structure and will not be described in detail here.

[0043] In this embodiment, the packaging device 300 further includes a labeler 330 and a sensor 340. The labeler 330 can be a printer, a laser marking machine or a conventional labeler, for example, a P3400 labeler specifically for cartons. The labeler 330 can be adaptively selected based on actual needs. The labeler 330 is arranged on the conveyor frame 210 of the conveying device 200. The sensor 340 is used to sense the position of the packaging box 500 on the conveying device 200. The sensor 340 can use a binocular camera to identify the position of the packaging box 500 through image acquisition of the binocular camera, or a distance sensor can be used to detect the distance from the packaging box through the distance sensor, or an optical fiber sensor can be used, which includes a transmitter and a receiver arranged relatively, when the packaging box does not pass between the transmitter and the receiver, the transmitter sends a signal to the receiver; when the packaging box passes between the transmitter and the receiver, the optical path between the transmitter and the receiver is blocked, and the receiver loses the signal. Under this working condition, it is considered that the packaging box labeler 330 is facing. In actual use, the optical fiber sensor may be disposed on the labeling machine 330 . When the optical path of the optical fiber sensor is blocked, it means that the position of the packaging box 500 is opposite to the position of the labeling machine 330 .

[0044] In other alternative embodiments, the sensor 340 may also adopt other existing technical means, which will not be described in detail here. In other alternative embodiments, the packaging device 300 may also include a tape sticking machine, a nailing machine, etc., which may be selected based on the functional adaptability required in the packaging process. The existing packaging equipment is not described in detail here.

[0045] The controller 400 is in communication connection with the weighing device 320, the conveying device 200, the discharging assembly 130, the sensor 340 and the labeling machine 330;

[0046] The sensor 340 is disposed on the conveying frame 210 of the conveying device 200 , and the sensor 340 transmits sensed position information to the controller 400 .

[0047] The weighing device 320 transmits the detected weight information to the controller 400; the controller 400 analyzes the working conditions based on the received information, and adaptively sends a shutdown or start signal to control the start or shutdown of each unit.

[0048] The controller 400 may include a CPU or other general-purpose processor, a display, a memory, etc.; the controller may also be a programmable logic device or a software system integrated in a host computer.

[0049] The controller 400 is configured to:

[0050] The weighing device 320 obtains the weight information of the packaging box and transmits the weight information to the controller 400. The controller 400 compares the weight information with the weight threshold. If the weight information is equal to the weight threshold, it means that the weight of the fruit particles in the packaging box 500 reaches the predetermined value. Then, the controller 400 sends a stop signal to the discharging component 130, and the discharging component 130 stops conveying the fruit particles into the packaging box 500. At the same time, the controller 400 sends a start signal to the conveying device 200 and the belt conveyor, i.e., the packaging platform 310. The belt conveyor starts to transfer the packaging box 500 on the belt conveyor to the conveying device 200. At the same time, the conveying device 200 starts so that the conveying device 200 transports the packaging box 500 filled with fruit particles to the designated location.

[0051] If the weight information is greater than or equal to the weight of the packaging box and less than the weight threshold, it means that the fruit particles in the packaging box do not reach the predetermined weight, and the controller 400 sends a start signal to the discharging component 130, and the discharging component 130 conveys the fruit particles into the packaging box; the controller 400 also sends a stop signal to the conveying device 200 to save energy;

[0052] If the weight information is less than the weight of the packing box, it means that there is no packing box on the packing platform, and the controller 400 sends a stop signal to the discharging component 130 and sends a stop signal to the conveying device 200.

[0053] When the weight information is equal to the weight threshold and the packing box is conveyed to the conveying device 200, the sensor 340 senses the position of the packing box 500 on the conveying device 200 and transmits the position information to the controller 400. If the position of the packing box 500 is relative to the position of the labeling machine 330 in the upper and lower directions or in the left and right directions, the controller 400 sends a start signal to the labeling machine 330 so that the labeling machine 330 labels the packing box 500.

[0054] The above-mentioned weight threshold may be a set value or a set range, and the weight threshold may be adaptively adjusted based on actual needs.

[0055] In other alternative implementations, the controller 400 may also be connected to communicate with other packaging devices and detect the position of the packaging box through the sensor 340. When the packaging box corresponds to the position of other packaging devices, the controller 400 controls the other packaging devices to start.

[0056] Further, such as Figure 4 and Figure 5 As shown, the de-fluffing assembly 110 includes a shell 111 , a de-fluffing roller 112 , a first screening net 113 and a fruit particle bucket 114 , wherein a fruit particle outlet 1116 is provided on the side of the shell 111 , and the fruit particle bucket 114 is externally connected to the fruit particle outlet 1116 .

[0057] The shell 111 is provided with a feed port 1111, and the outlet of the feed component 120 is connected to the feed port 1111. Specifically, the outlet of the feed component 120 is located directly above the feed port 1111, so that the chestnuts to be deboned can fall from the outlet of the feed component 120 into the feed port 1111.

[0058] Please continue to refer to Figures 3 to 5 As shown, the first screening net 113 is used to screen the chestnut fluff and fruit particles after depilation, and collect the fruit particles into the fruit particle bucket 114. The inlet end of the discharging assembly 130 is connected to the interior of the fruit particle bucket 114 to transport the fruit particles in the fruit particle bucket 114 to the packaging box 500.

[0059] The awning assembly 110 further includes a driving wheel 115 , and the driving wheel 115 is arranged on the housing 111 and can be driven to rotate around its own axis.

[0060] The first end ( Figure 5 The right end of the first screening net in the invention) is rotatably arranged on the shell 111, and the end can move left and right in the horizontal direction relative to the shell 111. Specifically, the right end of the first screening net 113 can be rotatably matched with the slider, and the slider can slide left and right in the horizontal direction with the shell 111.

[0061] The second end ( Figure 5 The left end of the first sieve mesh in the first driving wheel 115 is used as the discharging end to eccentrically rotate with the first driving wheel 115, the rotation axis of the first driving wheel 115 is parallel to the rotation axis of the first end of the first sieve mesh 113, and the second end of the first sieve mesh 113 can swing to a position lower than the first end of the first sieve mesh 113 during the swinging process of the first driving wheel 115, and the first end and the second end of the first sieve mesh 113 are two opposite ends of the first sieve mesh 113 along a horizontal direction. Please continue to refer to Figure 5 As shown, when the first driving wheel 115 rotates, the left end of the first screening net 113 swings up and down and moves forward and backward with the first driving wheel 115. At this time, the right end of the first screening net 113 rotates adaptively and moves linearly left and right, and the left end of the first screening net 113 forms a bumpy motion state, which is beneficial to the screening of chestnut pods and fruit particles on the first screening net 113 and is beneficial to improving the screening efficiency. At the same time, when the left end of the first screening net 113 swings downward and is lower than its right end, the left end of the first screening net 113 serves as a discharging end so that the screened chestnut pods roll from the left end of the first screening net 113 into the chestnut pod bucket 117.

[0062] The fruit particles fall below the first screening net 113 , and at this time, a fruit particle bucket 114 may be disposed below the first screening net 113 to receive the fruit particles.

[0063] Please continue to refer to Figure 5 As shown, in this embodiment, a secondary screening structure is added, and the de-puffing assembly 110 also includes a second screening net 116. The motion structure of the second screening net 116 is similar to that of the first screening net 113. The right end of the first screening net 113 serves as a discharging end, and its left end cooperates with the second driving wheel 119 in eccentric rotation. The right end of the first screening net 113 and the housing 111 swing up and down, that is, slide horizontally left and right. Both the first driving wheel 115 and the second driving wheel 119 are gears, which are meshed. In this embodiment, one of the driving wheels is driven to rotate by an external motor.

[0064] The mesh of the second sieve 116 is smaller than the mesh of the first sieve 113. The second sieve 116 is arranged below the first sieve 113. The first sieve 113 is used to screen the chestnut buds and make the fruit particles pass through the mesh of the first sieve 113 and fall into the second sieve 116. The second sieve 116 is used to screen the fruit particles and make the impurities such as the tiny chestnut buds fall through the mesh of the second sieve 116. When the right end of the second sieve 116 swings downward and is lower than the left end thereof, the fruit particles on the second sieve 116 pass through the right end of the second sieve 116 and roll into the fruit particle bucket 114.

[0065] The deflocculating roller 112 is arranged in the shell 111, and the deflocculating roller 112 can be driven to rotate around its own axis, and is used to rub and deflocculate the chestnuts to be deflocculated that enter through the feed port 1111. One deflocculating roller 112 can be provided, and the chestnuts to be deflocculated are kneaded when passing through the gap between the deflocculating roller 112 and the shell 111; or multiple deflocculating rollers 112 can be provided, and when the chestnuts to be deflocculated pass through the gap between adjacent deflocculating rollers, they are kneaded. In this embodiment, the deflocculating roller 112 is driven to rotate by an external motor.

[0066] For further information, please refer to Figures 5 to 7 As shown, the shell 111 includes an upper shell 1112 and a lower shell 1113. The upper shell 1112 is cylindrical with a central axis extending horizontally. The depilatory roller 112 is coaxially installed in the upper shell 1112. The gap between the depilatory roller 112 and the inner wall of the upper shell 1112 forms a kneading space. The feed port 1111 is opened in the upper shell 1112, and the upper shell 1112 is provided with a drop port 1114 connected to the lower shell 1113. The feed port 1111 is set at the top of the upper shell 1112, and the drop port 1114 is set at the bottom of the upper shell 1112. The feed port 1111 and the drop port 1114 are staggered along the axial direction of the upper shell 1112. Preferably, the feed port 1111 and the drop port 1114 are arranged on both sides of the axial direction of the upper shell 1112, so that the chestnuts to be shredded transported to the upper shell 1112 can stay in the upper shell 1112 for a longer time, thereby achieving a higher shredding rate.

[0067] The outer peripheral surface array of the deflocculating roller 112 is provided with deflocculating heads 1121, and the deflocculating heads 1121 rotate with the deflocculating roller 112 to knead the chestnuts to be deflocculated. When the deflocculating heads 1121 rotate to the bottom of the upper shell 1112, the gap between the deflocculating heads 1121 and the bottom of the inner wall of the upper shell 1112 is small, and the gap between the outer peripheral surface of the deflocculating roller 112 and the bottom of the inner wall of the upper shell 1112 is large, so when the chestnuts to be deflocculated are switched between the two gaps, a kneading shape is formed to improve the deflocculation rate.

[0068] Furthermore, the detangling head 1121 is made of elastic material, for example, known materials such as rubber or flexible plastic. The detangling head 1121 is in the shape of a truncated cone, and the small diameter end of the detangling head 1121 is connected to the outer wall of the detangling roller 112. The outer wall of the detangling head 1121 is in the shape of a conical slope. When the detangling head 1121 rotates to the bottom of the upper shell 1112, the gap between the outer wall of the detangling head 1121 and the bottom of the inner wall of the upper shell 1112 will gradually change, further improving its kneading effect. By setting the taper of the detangling head 1121 and the radial gap between the large diameter end of the detangling head 1121 and the inner wall of the upper shell 1112, the kneading force of the controller can be controlled to achieve a better kneading effect.

[0069] The large diameter end of the stripping head 1121 is an arc surface that bulges outward. When the stripping head 1121 rotates to the bottom of the upper shell 1112, the gap between the large diameter end of the stripping head 1121 and the bottom of the inner wall of the upper shell 1112 will gradually change, which is used to squeeze and rub the chestnuts to be stripped between the large diameter end of the stripping head 1121 and the bottom of the inner wall of the upper shell 1112. The outer wall of the stripping head 1121 is provided with a plurality of grooves 1122. Preferably, the grooves 1122 are hemispherical grooves, so that during the rubbing process, the chestnuts to be stripped can be partially sunken into the grooves, so that the stripping head 1121 has an instantaneous gripping ability, and this gripping ability is conducive to positioning the chestnut fluff located in the groove, so that the chestnut fluff in contact with one side of the inner wall of the upper shell 1112 will be torn by the rubbing force, so that the chestnut fluff located in the groove and the chestnut fluff located on the inner wall side of the upper shell 1112 are torn, so as to achieve a better stripping effect.

[0070] Please refer to Figures 6 to 8 As shown, the outer wall of the detangling roller 112 has a radially extending rigid connecting rod 1123, and the rigid connecting rod 1123 is radially connected to the outer wall of the detangling roller 112, and one end of the detangling roller 112 is detachably inserted into the rigid connecting rod 1123. The rigid connecting rod 1123 is preferably made of iron, copper or other metal rods, where rigidity is relative to elasticity. The provision of the rigid connecting rod 1123 is conducive to providing better rigid support for the detangling roller 112, and at the same time, a better kneading effect is achieved through the elastic deformation of the detangling roller 112 itself. At the same time, the provision of the rigid connecting rod 1123 is also convenient for the installation of the detangling roller 112.

[0071] Since chestnut fluff has many thorns on its surface, it is easy for chestnut fluff to scratch the fluff removal head 1121 during the fluff removal process. Therefore, the replacement of the fluff removal head 1121 is a technical issue that must be considered. Please continue to refer to Figure 7As shown, the rigid connecting rod 1123 is a tapered rod whose outer diameter gradually increases radially outward, and the small-diameter end of the detangling head 1121 has a tapered cavity adapted to the rigid connecting rod 1123, and the rigid connecting rod 1123 is conformably sleeved in the tapered cavity. The detangling head 1121 is made of elastic material, and the detangling head 1121 is pressed onto the rigid connecting rod 1123 by external force, so that the two form a reliable connection relationship, and this structure is conducive to replacing the detangling head 1121.

[0072] For further information, please refer to Figure 6 and Figure 7 As shown, the outer wall of the depilatory roller 112 is symmetrically provided with multiple rows of depilatory heads 1121 along the circumferential direction, and each row is provided with multiple depilatory heads 1121 arranged at equal intervals along the axial direction of the depilatory roller 112, and the depilatory heads 1121 in adjacent rows are staggered along the axial direction of the depilatory roller 112. When the depilatory roller 112 rotates, when each row of depilatory heads 1121 rotates to the bottom of the upper shell 1112, the vacant area of ​​the previous row can be kneaded, which is conducive to comprehensively improving the depilatory efficiency.

[0073] Please refer to Figures 7 and 8 The inner wall array of the upper shell 1112 is provided with elastic contact convex heads 1115, which are made of elastic material, such as rubber or flexible plastic. The provision of the elastic contact convex heads 1115 is conducive to the chestnuts to be peeled staying at the bottom of the upper shell 1112 for a longer time, and also forms a kneading structure between the elastic contact convex heads 1115 and the peeling head 1121, thereby improving the kneading effect.

[0074] The elastic contact convex head 1115 includes a spherical contact 11151 and an elastic rod 11152, and the spherical contact is connected to the inner wall of the upper shell 1112 through the elastic rod. The elastic rod 11152 can be a rubber rod, and when the elastic contact convex head 1115 is compressed, the elastic rod 11152 will bend, and when the elastic rod 11152 is elastically reset, it will drive the spherical contact 11151 back to hit the chestnuts to be peeled, so that the chestnuts to be peeled inside change their postures, so that each position of the chestnuts to be peeled can be evenly rubbed, thereby improving the fluffing effect.

[0075] The bottom of the inner wall of the upper shell 1112 is provided with a plurality of rows of elastic contact convex heads 1115 along the circumferential direction. Specifically, each row of elastic contact convex heads 1115 is provided at the lower half shell position of the upper shell 1112, and the inner wall at the upper half shell position is not provided with elastic contact convex heads 1115. Due to the existence of the elastic contact convex heads 1115, the gap between the inner wall at the lower half shell position and the fluffing roller 112 and the gap between the inner wall at the upper half shell position and the fluffing roller 112 are different. When the chestnuts to be detached pass through the feed port 13 and fall into the upper half shell position of the upper shell 1112, the gap is relatively large, and the chestnuts are loosened by squeezing the relatively large gap, and the chestnuts to be detached are initially kneaded at this time; then the chestnuts to be detached fall into the upper and lower half shell positions of the upper shell 1112, and because the elastic contact convex heads 1115 occupy part of the gap space, the gap becomes smaller, and two-stage kneading is formed for the chestnuts to be detached.

[0076] In each row, a plurality of elastic contact convex heads 1115 are arranged at equal intervals along the axial direction of the upper shell 1112, and the elastic contact convex heads 1115 of adjacent rows are staggered along the axial direction of the upper shell 1112. The staggered arrangement facilitates contact with chestnuts to be peeled at various positions. Moreover, the peeling heads 1121 form a rubbing result with the elastic contact convex heads 1115 of each row during the rotation of the peeling roller 112. Since the peeling heads 1121 of each row are axially staggered and the elastic contact convex heads 1115 of each row are axially staggered, during the rubbing process, the contact position of the peeling heads 1121 with the elastic contact convex heads 1115 of each row changes, so as to increase the rubbing coverage of the chestnuts to be peeled, and improve the peeling efficiency and the peeling rate.
