Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food production, and in particular to a precise quantitative automatic feeding device for bird's nest and a process. BACKGROUND

[0002] In the traditional bird's nest processing process, the soaked bird's nest silk needs to be filled into a container. At present, the wet material bird's nest feeding work completely depends on manual operation, and the vision requirement and experience of the personnel are very high, so the soaked bird's nest needs to be manually fed into the bird's nest container. This operation needs to be fed multiple times by manual operation to achieve the required sub-packaging amount. Not only is the operation procedure complicated, but also the efficiency is low, the accuracy is low, and manual operation needs to be repeated multiple times to meet the requirement of the standard addition amount. This leads to high labor cost in the bird's nest production process.

[0003] Therefore, a bird's nest sub-packaging device is disclosed in Chinese patent CN113602542A. The device comprises a conveying device and multiple filling units. The multiple filling units sequentially fill different amounts of bird's nest into the bird's nest bottle to complete sub-packaging. However, the device needs to use a material distribution wheel with blades to discharge the bird's nest, which can easily damage the bird's nest. Since the bird's nest is a high-value product, the weighing accuracy requirement is high, and the shape integrity requirement is also high. Therefore, the device cannot ensure the product quality of the bird's nest.

[0004] In the prior art, there are also devices that use powder quantitative feeding to sub-packaging bird's nest. However, the powder quantitative feeding does not have a strip-shaped requirement, which can damage the bird's nest and press out the internal moisture during the transition compression process, which can easily cause damage to the bird's nest and seriously affect the quality of the finished product. There are also devices that use screw conveying equipment to sub-packaging bird's nest. However, the screw can damage the bird's nest during rotation. For wet material bird's nest, the wet material bird's nest has high natural viscosity, which causes high pushing resistance, making it difficult to convey the material at the screw thread, and the sub-packaging cannot be smoothly performed.

[0005] Therefore, the present application provides a precise quantitative automatic feeding device for bird's nest to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] As shown in Figures 1 to 13 , the precise quantitative automatic feeding device for bird's nest of the present embodiment comprises a rack 1, a feeding device 2, a quantitative discharge device 3 and a blanking device 4.

[0026] As shown in Figure 1 , the feeding device 2, the quantitative discharge device 3 and the blanking device 4 can be installed on the rack 1.

[0027] Referring to Figures 6 to 9The feeding device 2 comprises a hopper 21 and an automatic feeding push rod 22; the hopper 21 has a storage chamber 211 therein, the storage chamber 211 has a discharge port 212, and the automatic feeding push rod 22 is used for automatically pushing the material in the storage chamber 211 out of the discharge port 212; the feeding device 2 can be one or multiple, and in the embodiment, the feeding device 2 is taken as an example of multiple arranged side by side to realize batch automatic production.

[0028] The quantitative discharge device 3 is arranged in correspondence with the number of the feeding device 2.

[0029] Referring to Figure 4 and Figure 5 , the quantitative discharge device 3 comprises a buffer cylinder 31, an automatic quantitative piston 32, a pressure detection mechanism 33 and a quantitative mechanism 34.

[0030] The buffer cylinder 31 has a buffer chamber 311 therein, the peripheral wall of the buffer chamber 311 is provided with a side wall opening 312 in communication with the discharge port 212 of the hopper 21, and the buffer chamber 311 is provided with the automatic quantitative piston 32 and a buffer chamber outlet 313 at two ends respectively, the automatic quantitative piston 32 can reciprocate along the two ends of the buffer chamber 311, and is used for pushing the material in the buffer chamber 311 to the buffer chamber outlet 313. The side wall opening 312 can be used for the material in the storage chamber 211 to enter the buffer chamber 311 from the side, so that the feeding is convenient, and the automatic quantitative piston 32 can reciprocate without leaving the end of the buffer chamber 311, so that the buffer chamber 311 is ensured not to bring impurities and the like.

[0031] The quantitative mechanism 34 comprises an automatic quantitative plate 341 and a bottom plate 342, and the automatic quantitative plate 341 and the bottom plate 342 of each quantitative mechanism 34 can be combined to form an entire plate body respectively.

[0032] The bottom plate 342 is arranged outside the buffer chamber outlet 313 at intervals, the automatic quantitative plate 341 is arranged between the buffer chamber outlet 313 and the bottom plate 342 in a reciprocating manner, and the automatic quantitative plate 341 has a movable metering chamber 3411 located opposite the buffer chamber outlet 313, the metering chamber 3411 penetrates through the automatic quantitative plate 341 at two ends, and when the feeding end 3412 of the metering chamber 3411 is located opposite the buffer chamber outlet 313, the other end discharging end 3413 is closed by the bottom plate 342 (as shown in Figure 5 ), so that the metering chamber 3411 can receive the material output from the buffer chamber 311; and when the feeding end 3412 of the metering chamber 3411 is away from the buffer chamber outlet 313 (as shown in Figure 4 ), the discharging end 3413 is open for discharging, that is, the automatic quantitative plate 341 can move to make the metering chamber 3411 separate from the buffer chamber 311, and output the material in the metering chamber 3411 to a clean container, so as to realize precise feeding.

[0033] The pressure detection mechanism 33 is used to detect the pressure of the material in the measuring chamber 3411 when the automatic dosing piston 32 pushes the material from the buffer chamber outlet 313 into the measuring chamber 3411.

[0034] The embodiment can ensure the consistency of the weight of the material output to the container each time by the pressure detection mechanism 33 cooperating with the fixed-volume measuring chamber 3411. For example, when the material is wet bird's nest, the volume of the bird's nest in the measuring chamber 3411 is always fixed when the bird's nest in the buffer chamber 311 is continuously pushed into the measuring chamber 3411 by the automatic dosing piston 32 at the same geographical location. When the detected pressure value reaches the preset fixed value, it means that the density of the bird's nest in the measuring chamber 3411 is also a fixed value, and the weight of the bird's nest in the measuring chamber 3411 at this time is the target value required for output. At the same time, the bird's nest is pushed by the automatic feeding push rod 22 and the automatic dosing piston 32 throughout the process, and the automatic dosing plate 341 is used to realize the output of the material, which can avoid the bird's nest from being damaged by stirring. The pressure is detected by the pressure detection mechanism 33 during the pushing process of the automatic dosing piston 32, which can avoid the bird's nest from being damaged by excessive extrusion, and effectively ensure the product quality.

[0035] Furthermore, by means of the above-mentioned device structure, the embodiment also proposes a precise automatic dosing process for bird's nest, which can include the following steps: S1, device reset: the automatic feeding push rod 22 is reset to the initial position, the automatic dosing piston 32 is reset to the initial position, and the automatic dosing plate 341 is reset to move the feeding end 3412 of the measuring chamber 3411 close to the buffer chamber outlet 313. The initial position of the automatic feeding push rod 22 is away from the discharge port 212, and the initial position of the automatic dosing piston 32 is located at the end of the buffer chamber 311 away from the buffer chamber outlet 313.

[0036] S2, bird's nest feeding: manually feeding the bird's nest into the storage chamber 211 of the hopper 21; see Figure 8 The top of the hopper 21 can have an opening 213 communicating with the storage chamber 211, and the opening 213 is provided with a movable cover plate 214 which can be opened and closed. Each hopper 21 arranged side by side can share one movable cover plate 214. Opening the movable cover plate 214 can facilitate batch feeding of wet bird's nest, and can also flatten the wet bird's nest for easy feeding.

[0037] S3, bird's nest buffering: the automatic feeding push rod 22 operates to push part of the bird's nest in the storage chamber 211 into the buffer chamber 311 through the discharge port 212 and the side wall opening 312.

[0038] In this embodiment, the buffer chamber 311 can be a cylindrical chamber, and the side wall opening 312 is located on the circumferential wall. The end of the automatic feeding push rod 22 near the discharge port 212 is an arc surface 221 adapted to the cylindrical chamber and can move to close the side wall opening 312. The discharge port 212 directly interfaces with the side wall opening 312 without a step therebetween, which can avoid obstruction and residue of bird's nest during transportation, and the arc surface 221 of the end surface of the automatic feeding push rod 22 can form a complete cylindrical chamber with the buffer chamber 311, which can also ensure that the bird's nest is not damaged by extrusion of the side wall of the buffer chamber 311.

[0039] In this embodiment, the capacity of the buffer chamber 311 can be designed to be greater than three times the capacity of the metering chamber 3411 according to the wet bird's nest material, so that when the automatic feeding push rod 22 feeds once, it can ensure that sufficient bird's nest can be pressed into the metering chamber 3411 by the automatic quantitative piston 32, reducing the number of repeated movements of the automatic quantitative piston 32 and improving production efficiency. Of course, the capacity of the buffer chamber 311 can also be designed to be other capacities, which are not limited to this. At the same time, the metering chamber 3411 can also be a cylindrical chamber. The inner diameter of the feeding end 3412 of the metering chamber 3411 is equal to the inner diameter of the buffer chamber outlet 313, so that there is no step between the buffer chamber outlet 313 and the feeding end 3412, which makes the buffer chamber 311 and the metering chamber 3411 smoothly connect and transition, ensuring that the bird's nest is not obstructed and residual, and will not be crushed. Moreover, the inner diameters of the buffer chamber 311 and the metering chamber 3411 can be not less than the maximum length of the bird's nest strips in the material, which can ensure that the bird's nest enters the buffer chamber 311 and the metering chamber 3411 more smoothly, reduce strip damage, and ensure high product quality.

[0040] S4, metering detection: the automatic quantitative piston 32 runs to push the bird's nest in the buffer chamber 311 into the metering chamber 3411 through the buffer chamber outlet 313 and the feeding end 3412, and controls the end of the stroke of the automatic quantitative piston 32 not to extend into the metering chamber 3411, and detects the pressure of the bird's nest in the metering chamber 3411 through the pressure detection mechanism 33. When the pressure detected by the pressure detection mechanism 33 reaches a preset value, the automatic quantitative piston 32 stops running, and step S5 is performed. After the automatic quantitative piston 32 completes a stroke, it is reset to the initial position, and then step S3 is repeatedly performed. Since the capacity of the buffer chamber 311 is greater than that of the metering chamber 3411, at least one filling of the metering chamber 3411 can be completed in one stroke of the automatic quantitative piston 32 from one end of the buffer chamber 311 to the other end, and the automatic quantitative piston 32 is controlled not to extend into the metering chamber 3411, which avoids excessive extrusion of the bird's nest and prevents the bird's nest from being damaged. The preset value of the pressure can be set according to the actual characteristics of the bird's nest.

[0041] S5, quantitative discharging: the automatic quantitative plate 341 moves to drive the metering chamber 3411 and the bird's nest therein away from the buffer chamber outlet 313, so that the metering chamber 3411 discharging end 3413 is opened for discharging, so as to realize quantitative discharging; then, the automatic quantitative plate 341 is reset, and steps S3 and S4 are repeatedly executed until the bird's nest in the hopper 21 is completely packed and discharged. Meanwhile, a flow line (not shown in the figure) can also be arranged at the discharging direction of the metering chamber 3411 discharging end 3413, and the bird's nest containers can be placed in batches on the flow line to batch receive the quantitative bird's nest output by the quantitative discharging device 3.

[0042] Therefore, the use of the device and the process can realize the automation of the bird's nest feeding, greatly improve the consistency of the bird's nest sorting, realize the quantitative discharging of the wet material bird's nest, reduce the product loss rate, improve the yield, reduce the labor cost, reduce the production cost, and improve the labor environment.

[0043] Further, in the device of the embodiment, as shown in Figure 4 and Figure 10 , the pressure detection mechanism 33 can be a pressure sensor, and can be arranged at the end of the automatic quantitative piston 32 close to the buffer chamber outlet 313, so as to accurately and timely detect the pressure of the bird's nest in the metering chamber 3411. Of course, the pressure detection mechanism 33 can also be arranged at the position of the bottom plate 342 for closing the metering chamber 3411 discharging end 3413 (not shown in the figure), or the pressure detection mechanism 33 can also be arranged at the inner wall of the metering chamber 3411 and the like.

[0044] As shown in Figure 6 and Figure 9 , the automatic feeding push rod 22 can be movably extended into the hopper 21 and located at one side of the left side or the right side of the storage chamber 211, and the discharging port 212 is located in front of the automatic feeding push rod 22 and at the corner of the storage chamber 211; the other side of the storage chamber 211 is provided with an automatic pressing plate 23; the automatic pressing plate 23 reciprocates left and right, and is used for pushing the material in the storage chamber 211 to the side close to the automatic feeding push rod 22. Therefore, the capacity of the hopper 21 can be improved, and the production efficiency can be improved, so as to ensure that the material can be concentrated to the automatic feeding push rod 22 and be fully pushed out of the discharging port 212.

[0045] Specifically, the movable hole 215 can be arranged at the bottom of the bin 21, the automatic pressing plate 23 can be connected with the movable plate 24 at the bottom, the movable plate 24 covers the bottom of the storage chamber 211 and the movable hole 215 and is used for receiving the material; the movable plate pushing mechanism 25 is arranged below the bin 21, the movable plate pushing mechanism 25 comprises a movable plate linear module 251 and a movable plate connecting block 252, the movable plate connecting block 252 is connected with the movable plate 24 and the movable plate linear module 251 at two ends respectively, the movable plate linear module 251 drives the movable plate connecting block 252 to reciprocate in the movable hole 215 and drives the automatic pressing plate 23 to move close to or away from the automatic feeding push rod 22, so as to realize the concentrated pushing of the material in the storage chamber 211. In practice, the movable plate 24 and the automatic pressing plate 23 do not need to move left and right frequently, and a pressure can push the material to the automatic feeding push rod 22.

The movable plate linear module 251 can be composed of a stepping motor, a screw, a bearing seat and a connecting rod.

[0047] Meanwhile, the front and rear edges of the automatic pressing plate 23 can be gap-fitted on the front and rear sidewalls of the storage chamber 211 of the bin 21 respectively, so as to reduce the friction; and the leftmost end and the rightmost end of each bin 21 can be provided with the side baffle 27 surrounding the end sides of all the bins 21, the side baffle 27 is provided with the air holes 271 at the front and rear sides and the bottom respectively, the air holes 271 are located on the front and rear edges of the automatic pressing plate 23 and are communicated with the storage chamber 211 respectively, and the air holes 271 are connected with the air blowing device (not shown in the figure).
