Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco processing technical field especially, relate to a sugar material recovery device. BACKGROUND

[0002] Sugar material refers to the sugar material added in the tobacco processing process or natural sweetener, and its main purpose is to improve the taste, aroma and combustion performance of the tobacco product formed in the processing, so as to achieve the functions of seasoning, aroma and moisture retention; wherein, the sugar material required in the tobacco processing process is stored in a sugar material tank, and after the sugar material adding process is completed, the excess sugar material in the sugar material tank needs to be recovered, so that it can be used continuously in the next tobacco processing, realizing the maximum utilization of resources.

[0003] At present, when the excess sugar material in the sugar material tank is recovered, the operator usually places the material bucket at the discharge port of the sugar material tank and opens the on-off valve of the discharge port, so that the excess sugar material in the sugar material tank flows directly into the material bucket through the discharge port; after the material bucket is filled, the operator transports the material bucket to the refrigeration device for refrigeration.

[0004] However, after the filling of the material bucket is completed, the total weight of the whole material bucket reaches more than 25kg, the labor intensity is large during the movement of the material bucket, and there is a safety hazard; at the same time, during the filling, the discharge port of the sugar material tank and the inlet port of the material bucket do not form a relatively fixed positional relationship, which may cause the sugar material to leak at the position between the discharge port of the sugar material tank and the inlet port of the material bucket during the flow recovery of the sugar material, thereby causing the loss and waste of the sugar material and polluting the workbench.

[0005] In view of the above problems, a sugar material recovery device is needed to solve the above problems. UTILITY MODEL CONTENTS

[0027] As an option, the weight sensor is provided in plurality, and each weight sensor is uniformly arranged along the circumference of the second support plate.

[0028] As an option, the support frame comprises:

[0029] Two vertical plates are oppositely arranged, the bottom end of the vertical plate is connected to the top end of the third support plate, and the vertical plate can be gapingly arranged in the avoiding opening;

[0030] A placing plate is connected to the two vertical plates, the placing plate is used for placing the material barrel, and the placing plate is matched with the avoiding opening.

[0031] As an option, the support frame further comprises:

[0032] Four limiting baffle plates are respectively connected to the four edges of the placing plate, and the material barrel is limited between the four limiting baffle plates.

[0033] As an option, the limiting baffle plate comprises:

[0041] The utility model discloses the beneficial effects are:

[0042] By setting clearance through holes and a support on the worktable, and setting clearance openings coaxial with the clearance through holes on the support, one end of the lifting component is positioned below the worktable, and the other end of the lifting component can pass through the clearance through holes and clearance openings along the Z-axis; one end of the conveying pipe is connected to the outlet of the sugar container used to hold the sugar; when sugar recovery is not required, the empty bucket is directly placed on the support by the robotic arm. At this time, the lifting component is located below the bucket, that is, the bucket is supported by the support, and the lifting component does not support the bucket. This avoids impact on the lifting component due to the operating error of the robotic arm when placing the empty bucket on the support. This design effectively protects the entire lifting assembly and extends its service life. When sugar needs to be recycled, the lifting assembly moves upward along the Z-axis through the clearance through-hole and clearance opening to support the bucket placed on the support. It can also push the bucket upward relative to the support along the Z-axis. At this point, the bucket is completely supported by the lifting assembly, and the support is completely detached from the bucket. When the bucket continues to move upward along the Z-axis to correspond to the outlet of the sugar tank, i.e., the other end of the conveying pipe can be directly inserted into the inlet of the bucket, the lifting assembly stops pushing the bucket upward along the Z-axis. This allows excess sugar in the sugar tank to pass sequentially through the outlet and the conveying pipe. The material enters the material bucket through the inlet, thus automatically recycling excess sugar from the sugar tank into the material bucket. After the material bucket has been recycled and filled, the lifting component moves the entire material bucket downward along the Z-axis until the material bucket is completely supported by the support frame. The lifting component is located below the material bucket, and then the robotic arm directly removes the recycled material bucket from the support frame. In other words, the recycled material bucket is supported by the support frame, and the lifting component does not support the material bucket. This avoids impact on the lifting component due to the robotic arm's operating error when removing a heavy material bucket from the support frame, thus better protecting the entire lifting component and improving its service life. Since there is no longer a need for manual handling of the heavy recycling bins, the labor intensity is reduced, recycling safety is improved, and the entire recycling process is time-saving, labor-saving, and highly efficient. Furthermore, during filling, a conveyor pipe connects the outlet of the sugar tank and the inlet of the recycling bin, creating a relatively fixed connection. Therefore, during the sugar recycling process, spillage between the outlet of the sugar tank and the inlet of the recycling bin is avoided, preventing sugar loss, waste, and contamination of the workbench. This improves the sugar recycling rate and ensures the cleanliness of the workbench. Attached Figure Description

[0055] All the features disclosed in the specification, or the steps in all the disclosed methods or processes, can be combined in any manner, except for mutually exclusive features and / or steps.

[0056] Any feature disclosed in the specification, unless specifically stated otherwise, can be replaced by other equivalent or similar features. That is, each feature is only one example in a series of equivalent or similar features, unless specifically stated. Throughout the specification, the same reference signs indicate the same elements.

[0057] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] This embodiment proposes a sugar material recovery device that automatically recovers excess sugar material from the sugar material tank, saving time and labor, achieving high recovery efficiency, reducing manual labor intensity during the recovery process, and ensuring recovery safety. Simultaneously, this sugar material recovery device avoids sugar material spillage during the recovery process, thereby improving sugar material utilization and ensuring a clean and tidy recovery environment. Both the sugar material and the sugar material tank are common structures in existing tobacco processing; therefore, their specific structures and working principles will not be described in detail here.

[0059] Specifically, such as Figures 1 to 3 As shown, the sugar recycling device includes a workbench 1, a support 2, a lifting assembly 3, a conveying pipe 4, a material tank 5, and a robotic arm. The workbench 1 has a clearance through-hole 11. The support 2 is connected to the workbench 1 and has a clearance opening 221, which is coaxially located above the clearance through-hole 11. One end of the lifting assembly 3 is located below the workbench 1, and the other end of the lifting assembly 3 can pass through the clearance through-hole 11 and the clearance opening 221 along the Z-axis. One end of the conveying pipe 4 is connected to the outlet of the sugar tank. When an empty material tank 5 is placed on the support 2, the lifting assembly 3 is located below the material tank 5. Furthermore, the lifting assembly 3 can pass through the clearance through hole 11 and clearance opening 221 upward along the Z-axis to support the material bucket 5 on the support 2, and can push the material bucket 5 upward relative to the support 2 along the Z-axis so that the material bucket 5 moves to the point where the other end of the conveying pipe 4 is inserted into the inlet 51 of the material bucket 5, that is, the other end of the conveying pipe 4 is correspondingly provided with a sugar recovery position; and the lifting assembly 3 can also drive the recovered material bucket 5 downward along the Z-axis so that the material bucket 5 is placed back on the support 2. At this time, the lifting assembly 3 is located below the material bucket 5; the robot is used to place the empty material bucket 5 on the support 2 and to remove the recovered material bucket 5 from the support 2.

[0060] Compared with the prior art, the sugar recycling device in this embodiment changes the specific recycling structure and method of sugar. By setting an avoidance through-hole 11 and a support 2 on the workbench 1, and setting an avoidance opening 221 coaxial with the avoidance through-hole 11 on the support 2, one end of the lifting component 3 is positioned below the workbench 1, and the other end of the lifting component 3 can pass through the avoidance through-hole 11 and the avoidance opening 221 along the Z-axis. One end of the conveying pipe 4 is connected to the outlet of the sugar container. When sugar recycling is not required, the empty bucket 5 is directly placed on the support 2 by a robotic arm. At this time, the bucket 5 is supported by the support 2, and the lifting component 3 does not support the bucket 5.Figure 2 As shown; when sugar needs to be recycled, the lifting assembly 3 passes through the clearance through-hole 11 and clearance opening 221 along the Z-axis to support the bucket 5 placed on the support 2, and can push the bucket 5 upward relative to the support 2 along the Z-axis. At this time, the bucket 5 is completely supported by the lifting assembly 3, and the support 2 is completely separated from the bucket 5. When the bucket 5 continues to move upward along the Z-axis to correspond to the position of the outlet of the sugar tank, that is, at this time the other end of the conveying pipe 4 can be directly inserted into the inlet 51 of the bucket 5, the lifting assembly 3 stops pushing the bucket 5 upward along the Z-axis, so that the excess sugar in the sugar tank enters the bucket 5 in sequence through the outlet, the conveying pipe 4 and the inlet 51, thereby realizing the automatic recycling of the excess sugar in the sugar tank into the bucket 5. Figure 1 As shown; after the material bucket 5 has finished recycling and filling, the lifting component 3 drives the material bucket 5 to move downward along the Z-axis until the material bucket 5 is completely supported by the bracket 2. The lifting component 3 is located below the material bucket 5, and then the robotic arm directly removes the recycled material bucket 5 from the bracket 2. That is, the recycled material bucket 5 is supported by the bracket 2, and the lifting component 3 does not support the material bucket 5. Since it is no longer necessary to manually move the heavy material bucket 5 after recycling, the labor intensity is reduced, the recycling safety is improved, and the whole recycling process is time-saving and labor-saving, with high recycling efficiency. At the same time, during filling, a conveying pipe 4 is connected between the outlet of the sugar tank and the inlet 51 of the material bucket 5, so that a relatively fixed connection position relationship is formed between the two. Therefore, during the sugar flow recycling process, the problem of sugar spillage at the position between the outlet of the sugar tank and the inlet 51 of the material bucket 5 can be avoided, thereby avoiding the loss and waste of sugar and the contamination of the workbench 1, thus improving the recycling rate of sugar and ensuring the cleanliness of the workbench 1.

[0061] And, as Figure 2 As shown, when the robotic arm places an empty bucket 5 onto the support 2, the bucket 5 is fully supported by the support 2, and the lifting assembly 3 does not support the bucket 5. This avoids impact on the lifting assembly 3 due to the robotic arm's operational error when placing the empty bucket 5 onto the support 2. Similarly, the recovered bucket 5 is also fully supported by the support 2, and the lifting assembly 3 does not support the bucket 5. This avoids impact on the lifting assembly 3 due to the robotic arm's operational error when removing a heavier bucket 5 from the support 2. Therefore, the impact of the robotic arm's handling of the bucket 5 on the lifting assembly 3 is minimized, thus better protecting the entire lifting assembly 3 and extending its service life. Figure 2 The material bucket 5 shown is placed directly on the support 2. Figure 2 The material bucket and Figure 1 The actual size of the material buckets is the same; the differences are only in the illustrations.

[0062] Specifically, the robotic arm can be a six-axis robotic arm commonly used in existing technologies, and the material hopper 5 is a square column structure material hopper 5. In the entire recycling process, the sugar tank and the conveying pipe 4 remain stationary, and the material hopper 5 can only be moved up and down along the Z-axis by the lifting component 3. The entire recycling operation is simple and convenient.

[0063] The following is a detailed description of bracket 2:

[0064] Furthermore, such as Figures 1 to 5 As shown, the bracket 2 includes two upright plates 21 and a first support plate 22; wherein, the two upright plates 21 are arranged opposite to each other, the bottom end of the upright plates 21 is connected to the top of the workbench 1, and the upright plates 21 are located at the outer edge of the clearance through hole 11, that is, the clearance through hole 11 is located between the two upright plates 21; the first support plate 22 is connected between the two upright plates 21 and covers the top of the clearance through hole 11, and the aforementioned clearance opening 221 is provided on the first support plate 22, so that the material bucket 5 can be placed on the first support plate 22, that is, a material bucket placement position is provided on the first support plate 22.

[0065] Specifically, such as Figure 5 As shown, the clearance opening 221 has a cross-shaped structure. A portion of the bottom surface of the material barrel 5 is placed on the first support plate 22, and another portion of the bottom surface of the material barrel 5 covers part of the clearance opening 221. On the one hand, this ensures that the material barrel 5 is placed stably on the first support plate 22, preventing the material barrel 5 from falling down along the Z-axis through the clearance opening 221 and out of the first support plate 22. On the other hand, this creates a certain gap between the material barrel 5 and the clearance opening 221, so that the lifting assembly 3 can pass through the gap and upward along the Z-axis through the clearance opening 221 to receive the material barrel 5, thus ensuring that there is no interference between the first support plate 22 and the lifting assembly 3.

[0066] The following is a detailed description of the lifting component 3:

[0067] Specifically, such as Figures 1 to 4 As shown, the lifting assembly 3 includes a drive component 31, a weighing module 32, and a support frame 33. The fixed end of the drive component 31 is located below the workbench 1, and the output end of the drive component 31 is driven to the bottom end of the weighing module 32. The bottom end of the support frame 33 is connected to the top end of the weighing module 32, and the gap of the support frame 33 is located within the clearance opening 221. That is, the support frame 33 can move up and down along the Z-axis within the clearance opening 221. The support frame 33 is used to place the material bucket 5. The drive component 31 is used to drive the weighing module 32 and the support frame 33 to move up and down along the Z-axis as a whole, so that the material bucket 5 can move upward along the Z-axis to insert the other end of the conveying pipe 4 into the inlet 51 of the material bucket 5, or so that the material bucket 5 can move downward along the Z-axis to be placed on the first support plate 22. The weighing module 32 is used to weigh the weight of the material bucket 5 on the support frame 33 in real time.

[0068] By setting the weighing module 32, the material bucket 5 can be pressed on the weighing module 32 during the process of recycling the sugar material, so that the weight of the material bucket 5 can be weighed in real time by the weighing module 32; when the weighing module 32 weighs that the material bucket 5 reaches a preset weight, such as 25 kg, or the weighing module 32 weighs that the weight in the material bucket 5 no longer changes, such as the excess sugar material in the sugar material tank has been delivered but the weight of the material bucket 5 is less than the preset weight, the material conveying pipe 4 stops the delivery of the sugar material, so as to facilitate the driving part 31 of the lifting assembly 3 to move the material bucket 5 downward along the Z axis to the first support plate 22; the whole process can realize the consistency and uniformity of the weight of the material bucket 5, and can timely ensure the cooperative movement between the driving part 31 and the material conveying pipe 4, so as to ensure the safety and reliability of the sugar material recycling.

[0069] Specifically, as shown in Figures 1 to 4 , the driving part 31 can be a linear cylinder, and the workbench 1 is horizontally placed on the ground through four supports 12, a base 34 is fixedly arranged between the four supports 12, and the fixed end of the driving part 31 is arranged on the base 34 to ensure the working stability of the driving part 31; the output end of the driving part 31 is connected to a driving rod 35, and the driving rod 35 is connected to the bottom end of the weighing module 32, so as to drive the weighing module 32 to move up and down along the Z axis through the driving rod 35.

[0070] Further, as shown in Figures 1 to 4 , the weighing module 32 includes a second support plate 321, a weight sensor 322, and a third support plate 323; wherein the second support plate 321 is located between the two vertical plates 21, the output end of the driving part 31 is drivingly connected with the second support plate 321, that is, the top end of the driving rod 35 is connected with the bottom end of the second support plate 321, and the second support plate 321 can pass through the avoiding through hole 11 along the Z axis; the weight sensor 322 is arranged on the second support plate 321; the third support plate 323 is arranged on the weight sensor 322, and the third support plate 323 is parallel below the first support plate 22, that is, the first support plate 22, the second support plate 321 and the third support plate 323 are arranged in parallel with each other, the bottom end of the support frame 33 is connected to the top end of the third support plate 323, and the third support plate 323 can pass through the avoiding through hole 11 along the Z axis.

[0071] It is worth noting that in order to limit the upward movement position of the bucket 5 along the Z axis, the third support plate 323 cannot pass through the avoidance hole 221 along the Z axis, that is, the first support plate 22 can block the continuous movement of the third support plate 323 along the Z axis, and the support frame 33 can pass through the avoidance hole 221 along the Z axis; and for the limitation of the downward movement position of the bucket 5 along the Z axis, it can be realized by the first support plate 22, that is, when the support frame 33 moves downward along the Z axis with the bucket 5 to the first support plate 22, the downward movement position of the bucket 5 along the Z axis can be limited.

[0072] Further, as shown in Figure 1 and Figure 4 , the weight sensor 322 is provided with a plurality of, each weight sensor 322 is uniformly arranged along the circumference of the second support plate 321, so as to be able to simultaneously weigh the bucket 5 through a plurality of weight sensors 322, so as to ensure the weighing accuracy and reliability of the weight of the bucket 5. Among them, the bottom end and the top end of the weight sensor 322 are respectively connected with an installation plate, so as to make the weight sensor 322 connect with the second support plate 321 and the third support plate 323 through two installation plates. In the embodiment, the weight sensor 322 is provided with three. Here, the specific number of weight sensors 322 is not limited.

[0073] It is worth noting that the above-mentioned lifting assembly 3 is located below the bucket 5 when the robot takes and places the bucket 5 on the first support plate 22, which specifically means that the entire weighing module 32 is completely separated from the bucket 5, so as to avoid the impact on each weight sensor 322 of the weighing module 32 of the lifting assembly 3 due to the operation error of the robot.

[0074] Further, as shown in Figures 1 to 4 , the support frame 33 includes two vertical plates 331 and a placing plate 332; wherein the two vertical plates 331 are oppositely arranged, the bottom end of the vertical plate 331 is connected to the top end of the third support plate 323, and the vertical plate 331 can be located in the avoidance hole 221 with a gap, that is, the vertical plate 331 can move up and down in the avoidance hole 221 along the Z axis, so as to ensure that the vertical plate 331 and the first support plate 22 will not interfere with each other; the placing plate 332 is connected to the two vertical plates 331, and the placing plate 332 is used for placing the bucket 5.

[0075] That is, the placing plate 332 is provided with a bucket support area for placing the bucket 5, and when the bucket 5 is placed on the first support plate 22, the distance between the bucket support area and the bottom end of the bucket 5 is 5mm-10mm, so as to better ensure that the robot will not affect or even damage the entire weighing module 32 when taking and placing the bucket 5.

[0076] Specifically, as shown in Figure 3 and Figure 4 , the placement plate 332 is in a cross-shaped structure, that is, the structure of the placement plate 332 matches the structure of the avoidance hole 221, so as to ensure that the placement plate 332 can pass through the avoidance hole 221 up and down along the Z axis; and the avoidance hole 11 is a circular hole, and the area of the avoidance hole 11 is greater than the area of the avoidance hole 221, so that the placement plate 332 and the vertical plate 331 can move up and down along the Z axis in the avoidance hole 11.

[0077] Further, as shown in Figures 1 to 4 , the support frame 33 further comprises four limiting baffle plates 333, and the limiting baffle plates 333 are respectively connected to the four edges of the cross-shaped placement plate 332, and the material bucket 5 is limited between the four limiting baffle plates 333, so that the material bucket 5 can be stably positioned on the material bucket supporting area of the placement plate 332 through the four limiting baffle plates 333, so as to ensure the position stability of the material bucket 5 on the placement plate 332.

[0078] Specifically, as shown in Figures 1 to 4 , the limiting baffle plate 333 comprises an L-shaped plate 3331 and an inclined plate 3332; wherein the L-shaped plate 3331 is connected to one edge of the placement plate 332, and the L-shaped plate 3331 is used for limiting and resisting the material bucket 5; and the inclined plate 3332 is connected to the top end of the L-shaped plate 3331, and gradually increases in the direction away from the placement plate 332 along the Z axis, that is, the adjacent two inclined plates 3332 are in a flared structure, so as to provide a guiding effect for the material bucket 5 on the placement plate 332 through the inclined plates 3332 of the four limiting baffle plates 333, thereby quickly and accurately taking and placing the material bucket 5 on the placement plate 332. Wherein, the L-shaped plate 3331 and the inclined plate 3332 can be an integral structure.

[0079] Specifically, as shown in Figure 1 and Figure 4 , the outer side of the L-shaped plate 3331 is flush with the outer side edge of the placement plate 332, that is, the L-shaped plate 3331 does not protrude outward relative to the placement plate 332, so as to ensure that the L-shaped plate 3331 can move up and down along the Z axis in the avoidance hole 221 synchronously with the placement plate 332, thereby making the movement of the material bucket 5 on the Z axis more smooth and reliable.

[0080] The material conveying pipe 4 is described in detail as follows:

[0081] Specifically, as shown in Figures 1 to 3 , Figure 6As shown, the feed pipe 4 includes a main pipe 41, a connecting pipe 42, a liquid outlet pipe 43 and a bending pipe 44; wherein the main pipe 41 is arranged obliquely downward from the sugar tank to the hopper 5, one end of the main pipe 41 is communicated with the discharge port of the sugar tank; one end of the connecting pipe 42 is communicated with the other end of the main pipe 41; one end of the liquid outlet pipe 43 is communicated with the other end of the connecting pipe 42, and the liquid outlet pipe 43 is arranged in a bending manner with the main pipe 41, that is, the connecting pipe 42 is used for bending and communicating the main pipe 41 and the liquid outlet pipe 43; the inlet of the bending pipe 44 is connected to the other end of the liquid outlet pipe 43 in a bending manner, and the outlet of the bending pipe 44 and part of the liquid outlet pipe 43 extend into the inlet port 51 of the hopper 5, so that the sugar in the entire feed pipe 4 can flow into the hopper 5 through the outlet of the bending pipe 44, thereby realizing automatic conveying and recycling of the sugar from the sugar tank to the hopper 5 through the feed pipe 4. Wherein, the sugar recovery position is arranged at the outlet of the bending pipe 44.

[0082] Specifically, a recycling pump and a solenoid valve are arranged on the main pipe 41, so as to provide power for the sugar to flow from the sugar tank to the hopper 5 through the recycling pump, and the solenoid valve is used to control the on-off of the main pipe 41, thereby realizing automatic start-stop of sugar recycling. Wherein, the recycling pump and the solenoid valve can adopt the pump and solenoid valve structure commonly used in the prior art.

[0083] Further, as shown in the figure, Figure 6 The angle α between the axis of the liquid outlet pipe 43 and the axis of the bending pipe 44 is obtuse, so that the bending pipe 44 has an upward inclined extension trend relative to the liquid outlet pipe 43, so as to provide a buffer force for the sugar when the sugar flows into the bending pipe 44, and then make the buffered sugar flow into the hopper 5, thereby reducing the impact of the sugar output from the feed pipe 4, and further reducing the sugar spatter to the hopper 5, so as to further reduce the loss of sugar. Wherein, the sugar involved in the embodiment is in a liquid state.

[0084] The specific working process of the sugar recycling device in the embodiment is as follows:

[0085] Firstly, the mechanical hand places the empty hopper 5 on the hopper placing position on the first supporting plate 22, at this time, the spacing between the hopper supporting area on the placing plate 332 and the bottom end surface of the hopper 5 is 5mm-10mm; then, when the sugar needs to be recycled, the driving part 31 drives the second supporting plate 321 to move upward along the Z axis, so as to drive the four limiting baffles 333 to pass through the avoiding hole 221 along the Z axis, until the placing plate 332 abuts against the bottom end surface of the hopper 5, so that the placing plate 332 supports the hopper 5, that is, at this time, the hopper 5 is placed on the hopper supporting area on the placing plate 332.

[0086] Then, the driving member 31 continues to drive the second support plate 321 to move upward along the Z-axis, so that the bucket 5 is completely separated from the first support plate 22, until the bucket 5 moves upward along the Z-axis to the sugar recovery position, at this time, the outlet of the bending pipe 44 and part of the liquid outlet pipe 43 automatically extend into the inlet 51 of the bucket 5.

[0087] Then, the recovery pump and the electromagnetic valve on the main pipe 41 are opened, so that the excess sugar in the sugar tank can be pumped into the bucket 5 through the conveying pipe 4; at the same time, the three weight sensors 322 weigh the weight of the entire bucket 5 in real time; when the weight sensor 322 weighs that the bucket 5 reaches the preset weight, or the weight sensor 322 weighs that the weight of the bucket 5 no longer changes, that is, the excess sugar in the sugar tank has been transported but the weight of the bucket 5 is less than the preset weight, the recovery pump and the electromagnetic valve on the main pipe 41 are closed, so that the conveying pipe 4 stops conveying sugar to the bucket 5.

[0088] Then, the driving member 31 drives the second support plate 321 to move downward along the Z-axis, so as to drive the support frame 33 and the bucket 5 thereon to move downward along the Z-axis as a whole, until the bucket 5 moves downward along the Z-axis to the bucket placement position on the first support plate 22, at this time, the bucket 5 is supported by the first support plate 22.

[0089] Then, the driving member 31 drives the second support plate 321 to continue to move downward along the Z-axis, so as to drive the vertical plate 331, the placement plate 332 and the limiting baffle 333 to continue to move downward along the Z-axis as a whole, at this time, the bucket 5 no longer moves downward along the Z-axis with the placement plate 332, until the spacing between the bottom end surface of the bucket 5 and the placement plate 332 is 5mm-10mm.

[0090] Finally, the robot takes away the bucket 5 on the first support plate 22, so as to complete the entire automatic recovery process of the sugar.

[0091] The sugar recovery device in the embodiment can realize automatic recovery of the sugar, reduce the degree of manual participation and labor intensity, and ensure the safety during the recovery process, by setting the lifting assembly 3 capable of driving the bucket 5 to move upward and downward along the Z-axis, and cooperating the lifting assembly 3 with the bracket 2.

[0092] The sugar material recovery device in the embodiment drives the weighing module 32 and the support frame 33 to move up and down along the Z axis through the driving member 31, so as to drive the material bucket 5 to move to the sugar material recovery position corresponding to the material conveying pipe 4, so as to facilitate the recovery of the sugar material, and the material bucket 5 can also be driven to move to the material bucket placing position on the first support plate 22, so as to support the material bucket 5 through the first support plate 22, so that the weighing module 32 is completely separated from the material bucket 5 when the material bucket 5 on the first support plate 22 is taken and placed by the mechanical arm, thereby avoiding the influence of the mechanical arm on the weighing module 32 when the material bucket 5 is taken and placed, so as to better improve the service life of the entire lifting assembly 3.

[0093] The sugar material recovery device in the embodiment is uniformly arranged with a plurality of weight sensors 322 along the circumference of the second support plate 321, so that the material bucket 5 can be weighed by the plurality of weight sensors 322 at the same time, thereby ensuring the weighing accuracy and reliability of the weight of the material bucket 5, and ensuring the weight accuracy and consistency of the sugar material recovered in each material bucket 5.

[0094] The sugar material recovery device in the embodiment has the upwardly inclined extension trend of the bent pipe 44 of the material conveying pipe 4 relative to the liquid outlet pipe 43, so that when the sugar material flows into the bent pipe 44, the upwardly bent inclined structure of the bent pipe 44 provides a buffering force for the sugar material, and then the buffered sugar material flows into the material bucket 5, thereby reducing the impact of the sugar material output from the material conveying pipe 4, and further reducing the splashing of the sugar material outside the material bucket 5, so as to further reduce the loss of the sugar material.

[0095] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range will be changed, and the content of the specification should not be understood as a limitation of the present application.​
