Description

Technical Field

[0001] The present invention relates to the technical field of bamboo shoot sorting and quick-freezing, and particularly to a quick-freezing machine with automatic bamboo shoot length sorting. Background Art

[0002] A quick-freezing machine with automatic bamboo shoot length sorting is a device specifically used for processing bamboo shoots. It has an automated sorting function that can classify bamboo shoots according to their length for classification processing before quick-freezing. Such a quick-freezing machine is usually equipped with sensors and an automatic control system that can accurately measure the length of bamboo shoots and classify them into different length grades according to set standards. The sorted bamboo shoots will be sent into the quick-freezing chamber for quick-freezing to maintain the freshness and nutrition of the bamboo shoots.

[0003] In the prior art, when the bamboo shoots after length sorting enter the quick-freezing machine for quick-freezing operation, they are only transported into the quick-freezing machine through two conveyor belts. This transmission method will cause the bamboo shoots to stack up. The stacked bamboo shoots will cause blockages, resulting in the air and freezing medium not flowing evenly through the bamboo shoots, so that the freezing effect on the bamboo shoots during quick-freezing is uneven. Some bamboo shoots will not be frozen thoroughly or will be over-frozen. Further, the stacked bamboo shoots will also cause surface extrusion and deformation, resulting in damage to the appearance and taste of the bamboo shoots, thus reducing the quality and market value of the bamboo shoots. In addition, voids or areas with higher local density will be generated between the stacked bamboo shoots. These areas have poor cooling effects during quick-freezing, resulting in incomplete freezing of the bamboo shoots.

[0004] In addition, after the bamboo shoots are sorted by length, when the bamboo shoots of the same length specification enter the quick-freezing operation, due to the uneven thickness of the bamboo shoots, and the different heat transfer speeds of bamboo shoots with different thicknesses during quick-freezing, the quick-freezing process will be uneven. Some thin bamboo shoots will be over-frozen, while some thick bamboo shoots will not be completely quick-frozen. Furthermore, during quick-freezing, due to the different surface areas and volumes of the bamboo shoots, the thick bamboo shoots will be quick-frozen faster, while the thin bamboo shoots will be quick-frozen slower, resulting in inconsistent quality of the quick-frozen bamboo shoots and affecting the product quality.

[0005] Therefore, a quick-freezing machine with automatic bamboo shoot length sorting is proposed to solve the above problems. Summary of the Invention

A convex block is fixedly connected to the side of the auxiliary box far from the swing block, and there are two groups of convex blocks. The other group of convex blocks is synchronously arranged at the position on the inner wall of the quick-freezing chamber corresponding to the convex block on the auxiliary box, and the side of the auxiliary box far from the swing block is rotatably connected to the inner wall of the quick-freezing chamber.

[0012] Preferably, the material processing mechanism includes an extension rod, which is fixedly connected to the synchronous column. The end of the extension rod far from the synchronous column extends into the auxiliary box. A cleaning plate is fixedly connected to the part of the extension rod located in the auxiliary box.

[0014] Preferably, the upper end of the auxiliary box is an inclined guide groove, and the aggregate trough body is communicated with the inner cavity of the auxiliary box.

[0016] Compared with the prior art, the present invention provides a quick-freezing machine with automatic bamboo shoot length sorting, which has the following beneficial effects:

[0017] 1. Through the setting of the auxiliary quick-freezing mechanism, the rotation of the turntable drives the synchronous column to rotate, and then the auxiliary column to the swing block swings on the quick-freezing belt, so that the bamboo shoots are put into different positions on the quick-freezing belt through the swing of the collecting trough body, preventing the bamboo shoots from falling and stacking at the same position when they are transferred from the feeding belt to the quick-freezing belt, helping to ensure that the bamboo shoots are evenly cooled and frozen in the quick-freezing machine, helping to ensure that the entire batch of bamboo shoots can be effectively frozen, reducing quality problems caused by uneven freezing, and further transferring the bamboo shoots by swinging to ensure that the bamboo shoots are separated individually, preventing surface extrusion and deformation caused by stacking, preventing damage to the appearance and taste of the bamboo shoots, ensuring product integrity and appearance, and avoiding gaps or local high-density areas between the stacked bamboo shoots, resulting in poor cooling effect during the quick-freezing process, resulting in incomplete freezing of the bamboo shoots.

[0018] 2. Through the setting of the protrusions, when the aggregate trough swings to release the bamboo shoots, the friction between the two protrusions produces fluctuations, which in turn drives the auxiliary box to vibrate, thereby preventing the auxiliary box from being blocked when transmitting the bamboo shoots. Further, under the action of vibration, the bamboo shoots can be evenly distributed on the quick-freezing belt, which helps to achieve a uniform quick-freezing process. Avoiding blockage helps to reduce downtime in the production process, ensure the normal operation of the production line, and improve production efficiency and output.

[0019] 3. Through the setting of the material handling mechanism, the rotation of the turntable drives the auxiliary box to swing and then assists in the laying of the bamboo shoots, while driving the bristles inside the auxiliary box to move left and right to remove impurities such as bamboo shoot skins on the bamboo shoots, thereby preventing the presence of impurities such as bamboo shoot skins during quick freezing from affecting the quality of the bamboo shoots, making the bamboo shoots cleaner, and improving the sanitary quality and taste of the product. The peeling of impurities such as bamboo shoot skins attached to the bamboo shoots that affect the appearance of the bamboo shoots is more helpful to maintain the fresh taste of the bamboo shoots, and can effectively avoid the fibrosis and softening problems caused by direct quick freezing, and can ensure that consumers get the best taste experience when eating.

[0020] 4. By setting up a visual sensor, feedback is provided for thick bamboo shoots that exceed the specifications. Subsequently, with the cooperation of the telescopic rod and the pushing plate, screening and collection are carried out. After screening out the thick bamboo shoots that exceed the specifications, they are collected. Furthermore, the thick bamboo shoots are separately subjected to a quick-freezing operation set in another procedure, and then the thin bamboo shoots are transported to the quick-freezing belt for quick-freezing operation, preventing the uneven thickness of the bamboo shoots from causing uneven heat transfer speed during the quick-freezing process, resulting in an uneven quick-freezing process, and preventing over-freezing caused by the different surface area to volume ratios of the bamboo shoots, where the thin bamboo shoots freeze faster, while the thick bamboo shoots freeze slower and are not fully quick-frozen.

[0042] The material handling mechanism 3 is used to brush the bamboo shoots conveyed by the feeding belt 101 to prevent impurities from adhering and affecting the quick-freezing quality, and to sort and collect the over-sized bamboo shoots for quick-freezing operation. The material handling mechanism 3 includes an extension rod 301, which is fixedly connected to the synchronous column 204. One end of the extension rod 301 away from the synchronous column 204 extends into the auxiliary box 209. A cleaning plate 302 is fixedly connected to the part of the extension rod 301 located inside the auxiliary box 209.

An expansion rod 305 is arranged above the vision sensor 304. The vision sensor 304 and the expansion rod 305 are electrically connected and connected to the same external controller. The expansion rod 305 is mainly used to push the push plate 306 to push the thick bamboo shoots piled up on the auxiliary box 209. The expansion rod 305 is fixedly connected to the inner wall of the auxiliary box 209. A push plate 306 is fixedly connected to the side of the expansion rod 305 away from the aggregate chute 208. A sealing piece 307 is fixedly connected to the inside of the end of the auxiliary box 209 away from the vision sensor 304. The sealing piece 307 is made of flexible plastic material and is composed of two openable parts. A conveying pipe 308 is fixedly connected to the outer surface of the end of the auxiliary box 209 away from the vision sensor 304. The conveying pipe 308 is mainly used to convey the sorted thick bamboo shoots for collection. The conveying pipe 308 passes through the quick-freezing room 102, and a collection box is arranged at the end of the conveying pipe 308 away from the auxiliary box 209 to collect the screened thick bamboo shoots.

[0043] The working principle of all the contents in the above embodiments is as follows:

[0044] In the initial state: The bamboo shoots sorted by length are conveyed on the feeding belt 101. The positioning shaft 202 has not started to rotate yet. No bamboo shoots are placed in the aggregate chute 208 and the auxiliary box 209 yet. The expansion rod 305 has not started to push the push plate 306 to extend, and the sealing piece 307 is in a closed state.

[0045] The following is the working process of the auxiliary quick-freezing mechanism 2 used to swing the bamboo shoot materials conveyed on the auxiliary feeding belt 101 so that they can be evenly laid on the quick-freezing belt 103:

[0046] When in use, the feeding belt 101 transfers the bamboo shoots sorted by length to one end close to the auxiliary box 209, and then under continuous transmission, the bamboo shoots on the feeding belt 101 fall into the collecting trough 208, and continue to fall into the auxiliary box 209 under the action of the oblique guide groove of the collecting trough 208. When the bamboo shoots are transferred and dropped, the operator starts the built-in power supply of the positioning shaft 202 through the external controller, and the positioning shaft 202 drives the turntable 203 to rotate clockwise. When the turntable 203 rotates clockwise, the rotation of the turntable 203 drives the synchronous column 204 to rotate clockwise with the positioning shaft 202 as the axis. When the synchronous column 204 rotates around the positioning shaft 202, the synchronous column 204 moves back and forth left and right on the auxiliary column 206 under the action of the rotation. The movement of 204 on the auxiliary column 206 synchronously drives the auxiliary column 206 to drive the swing block 205 and the connecting shaft 207 to swing with the connecting shaft 207 as the axis. When the swing block 205 swings, since the collection tank body 208 is fixedly connected to the swing block 205, the collection tank body 208 and the swing block 205 maintain synchronous swinging motion. At this time, the bamboo shoots that fall into the collection tank body 208 through the auxiliary box 209 are displaced on the quick-freezing belt 103 under the swinging action of the collection tank body 208, and the bamboo shoots inside are shaken off to different positions on the quick-freezing belt 103 for quick-freezing and conveying. By expanding the falling range of the bamboo shoots, the bamboo shoots conveyed by the feeding belt 101 are further prevented from falling on the quick-freezing belt 103 and stacking together.

[0047] Furthermore, when the auxiliary box 209 swings, the protrusion 210 fixedly connected to the auxiliary box 209 swings synchronously, and since the inner surface of the quick-freezing room 102 is also fixedly connected with the protrusion 210, when the auxiliary box 209 swings, the auxiliary box 209 drives the protrusion 210 connected on one side to swing, and then in the process of resetting, it conflicts with the protrusion 210 connected to the inner wall of the quick-freezing room 102, and then under the conflict transmission, the auxiliary box 209 is vibrated through the protrusion 210, so as to prevent the lower port from being blocked when the bamboo shoots are transferred to the quick-freezing belt 103 through the inner cavity of the auxiliary box 209;

[0048] With the aid of the auxiliary quick-freezing mechanism 2, as the turntable 203 rotates, it drives the synchronous column 204 to rotate, and then makes the auxiliary column 206 to the swing block 205 swing on the quick-freezing belt 103, so as to swing and place the bamboo shoots onto different positions on the quick-freezing belt 103 through the swing of the aggregate chute 208, preventing the bamboo shoots from falling onto the same position and stacking when being conveyed from the feeding belt 101 to the quick-freezing belt 103, helping to ensure that the bamboo shoots are evenly cooled and frozen in the quick-freezing machine, contributing to ensuring that the whole batch of bamboo shoots can be effectively frozen, reducing the quality problems caused by uneven freezing, and further conveying the bamboo shoots by swinging can ensure that the bamboo shoots are separated individually, preventing surface extrusion and deformation caused by stacking, preventing damage to the appearance and taste of the bamboo shoots, ensuring product integrity and appearance aesthetics, and avoiding the generation of voids or areas with higher local density between the stacked bamboo shoots, resulting in poor cooling effect during the quick-freezing process and incomplete freezing of the bamboo shoots.

[0049] With the aid of the bump 210, when the aggregate chute 208 swings and places the bamboo shoots, the contact between the two bumps 210 generates fluctuations, which then drives the auxiliary box 209 to vibrate, preventing the auxiliary box 209 from being blocked when transporting the bamboo shoots. Further, under the action of vibration, it can ensure that the bamboo shoots are evenly distributed on the quick-freezing belt 103, contributing to achieving a uniform quick-freezing process. Avoiding blockage helps to reduce the downtime during the production process, ensure the normal operation of the production line, and improve production efficiency and output.

[0050] Please refer to the above working process Figures 1 to 5 。

[0051] The following is the working process of the material processing mechanism 3 for brushing the bamboo shoots conveyed by the feeding belt 101 to prevent impurities from adhering and affecting the quick-freezing quality, and sorting and collecting the oversized bamboo shoots for quick-freezing operation:

[0052] During use, the positioning shaft 202 drives the turntable 203 to rotate clockwise. Then, when the synchronous column 204 moves left and right on the auxiliary column 206, the left and right movement of the synchronous column 204 synchronously drives the extension rod 301 to move left and right. Since the extension rod 301 extends into the auxiliary box 209 and is fixedly connected to the cleaning plate 302, therefore, when the synchronous column 204 drives the extension rod 301 to move left and right reciprocally, the left and right movement of the extension rod 301 in the auxiliary box 209 synchronously drives the cleaning plate 302 to move left and right in the auxiliary box 209. And the bristles 303 provided on the cleaning plate 302 rub against the bamboo shoots falling in the auxiliary box 209 during the left and right movement, peeling off the impurities such as bamboo shoot skins attached to the bamboo shoots, which affect the aesthetics of the bamboo shoots, helping to maintain the fresh taste of the bamboo shoots, effectively avoiding the problems of fibrosis and softening caused by direct rapid freezing, and ensuring that consumers can obtain the best taste experience when eating;

[0053] Further, when bamboo shoots fall onto the aggregate chute 208 on the feeding belt 101 and are then transferred to the auxiliary box 209, since the spacing of the upper feeding ports of the auxiliary box 209 is set as a fixed spacing, at this time, the thick bamboo shoots exceeding the width of the upper feeding ports of the auxiliary box 209 are stuck in the inclined guide chute above the auxiliary box 209, while the thin bamboo shoots normally pass through the inner cavity of the auxiliary box 209 and fall onto the quick-freezing belt 103 for reverse quick-freezing operation. When the thick bamboo shoots are stuck at the upper end of the auxiliary box 209 and cannot fall, the visual sensor 304 recognizes the existence of the thick bamboo shoots at this time and transmits a signal to the external controller. Then, the external controller drives the telescopic rod 305 to extend, pushing the push plate 306 to slide in the inclined guide chute at the upper end of the auxiliary box 209, pushing the thick bamboo shoots to the end of the blocking piece 307. Under the thrust, the thick bamboo shoots push open the blocking piece 307 and then are pushed into the material transfer pipe 308 and fall into the collection box for collection. After that, the thick bamboo shoots are subjected to a quick-freezing operation set by another program to prevent uneven quick-freezing caused by uneven thickness of the bamboo shoots.

[0054] Through the setting of the material handling mechanism 3, when the rotation of the turntable 203 drives the auxiliary box 209 to swing and assist in laying the bamboo shoots, it also drives the brush hairs 303 inside the auxiliary box 209 to move left and right to remove impurities such as bamboo shoot skins on the bamboo shoots, preventing the existence of impurities such as bamboo shoot skins from affecting the quality of the bamboo shoots during quick-freezing, making the bamboo shoots cleaner, improving the hygienic quality and taste of the product, and stripping the impurities such as bamboo shoot skins attached to the bamboo shoots that affect the aesthetic degree of the bamboo shoots, which is more conducive to maintaining the fresh taste of the bamboo shoots. It can effectively avoid problems such as fibrosis and softening caused by direct rapid freezing and ensure that consumers obtain the best taste experience when eating.

[0055] Through the setting of the visual sensor 304, feedback is given on the thick bamboo shoots exceeding the specifications. Then, with the cooperation of the telescopic rod 305 and the push plate 306, screening and collection are carried out. After screening out the thick bamboo shoots exceeding the specifications, they are collected. Furthermore, the thick bamboo shoots are separately subjected to a quick-freezing operation set by another program, and then the thin bamboo shoots are transported to the quick-freezing belt 103 for quick-freezing operation, preventing the uneven situation of the quick-freezing process caused by the different heat transfer speeds of bamboo shoots of different thicknesses during quick-freezing, and preventing the situation of over-freezing caused by the faster quick-freezing of thin bamboo shoots due to the different surface area to volume ratios of bamboo shoots, while the thick bamboo shoots are frozen more slowly and not completely frozen.
