[0018] The application provides a feeding device, which realizes automatic and continuous feeding of materials through multi-stage temporary storage cavities and coordinated control, and the specific working principle is as follows:

[0019] Material temporary storage and segmented control: the feeding pipe extends in the vertical direction and is divided into a plurality of temporary storage cavities by a plurality of valve members, and each temporary storage cavity can independently store materials (such as peanut bags).

[0020] In the initial state, the valve member is in the disconnected state, the material enters the uppermost temporary storage cavity from the top of the feeding pipe and is temporarily stored; when the uppermost temporary storage cavity is filled, the valve member is switched to the connected state, the material falls into the lower temporary storage cavity under the action of gravity, and then the valve member returns to the disconnected state, realizing the segmented interception of the material.

[0034] In the related art, in the existing food processing or packaging production line, the automatic feeding of materials is one of the key links to improve production efficiency. The feeding of granular materials such as peanuts usually needs to be put into the packaging box manually to ensure the accuracy and continuity of feeding. However, this way needs to take materials one by one manually, and the feeding efficiency is low, time-consuming and laborious.

[0035] As shown in FIG. 1 and Figure 2 To solve the above technical problems, the present application provides a feeding device, which comprises at least one feeding pipe 100 and a plurality of valve pieces 300, the feeding pipe 100 is arranged from bottom to top;

[0036] A plurality of valve members 300 are arranged on each feeding pipe 100, and the valve members 300 are arranged at intervals along the length direction of the feeding pipe 100, so that temporary storage cavities 120 are formed between adjacent valve members 300, and the temporary storage cavities 120 are used for temporarily storing materials.

[0037] In these embodiments, a device is provided to realize automatic continuous feeding, and specifically, the feeding device comprises the following key components:

[0038] The feeding pipe 100 comprises at least one feeding pipe 100 arranged vertically from bottom to top. The vertical design helps to utilize gravity to assist the flow of materials. That is, under the action of gravity, the materials can move along the feeding pipe 100 without the aid of external power.

[0039] A plurality of valve members 300 are arranged on each feeding pipe 100, and the valve members 300 are arranged at intervals along the length direction of the feeding pipe 100. For example, the number of valve members 300 on each feeding pipe 100 can be 2, 3, 4, 5, 6, 7, 8, or 9, etc.

[0040] By arranging a plurality of valve members 300 on the feeding pipe 100, a plurality of temporary storage cavities 120 are formed between adjacent valve members 300. These temporary storage cavities 120 are used for temporarily storing materials (such as granular materials such as peanut packs).

[0041] The valve member 300 can control the state of its adjacent temporary storage cavity 120, so that it can be switched between the "connected" and "disconnected" states. When in the connected state, the adjacent temporary storage cavities 120 form a continuous material channel, allowing the materials to flow from one temporary storage cavity 120 to the next layer; and when in the disconnected state, the flow of materials is cut off, so that the materials are temporarily stored in the current temporary storage cavity 120.

[0042] For example, the valve member 300 can be a plug valve.

[0043] That is, the automatic continuous feeding of materials is realized by the coordinated control of the multi-stage temporary storage cavities 120, and the specific working principle is as follows:

[0044] Material storage and segmented control: The feeding pipe 100 extends in the vertical direction, and is divided into a plurality of temporary storage cavities 120 by a plurality of valve members 300 inside, and each temporary storage cavity 120 can independently store materials (such as peanut packs).

[0045] In the initial state, the valve member 300 is in the off state, and the material enters the uppermost temporary storage cavity 120 from the top of the feeding pipe 100 and is temporarily stored; when the upper temporary storage cavity 120 is filled, the valve member 300 switches to the connected state, and the material falls into the lower temporary storage cavity 120 under the action of gravity, and then the valve member 300 returns to the off state, realizing the segmented interception of the material.

[0046] Continuous feeding mechanism: when the bottommost temporary storage cavity 120 needs to be fed, the valve member 300 below it is opened, and the material is released into the packaging box; at the same time, the adjacent valve member 300 above it is switched to the connected state in turn, so that the upper material moves down step by step to make up, forming a ladder type material flow. Through the alternating opening and closing of the valve member 300, continuous supply and accurate feeding of the material are realized, avoiding the discontinuity problem of manual feeding one by one. Of course, the opening and closing of the valve member 300 can be automatically triggered by a sensor or a timing controller according to the packaging box in-place signal or the production rhythm, to ensure that the feeding and packaging actions are synchronized.

[0047] Therefore, through the alternating feeding of multiple temporary storage cavities 120, seamless connection and feeding of the material are realized, the feeding speed is significantly improved, and it is suitable for high-speed production lines, and the efficiency is several times higher than manual feeding. The segmented control of the valve member 300 can accurately adjust the amount of single feeding (such as the fixed capacity of each temporary storage cavity 120). It completely replaces the manual taking and placing operation, reduces the labor intensity and labor cost of workers, and is especially suitable for long-time and large-batch production scenes. Among them, the number of feeding pipes 100 and the distance between valve members 300 can be adjusted according to the size of the material or the packaging demand to adapt to the feeding task of different materials.

[0048] In some embodiments, the number of feeding pipes 100 is multiple, and all the feeding pipes 100 are arranged side by side.

[0049] In these embodiments, the feeding device takes into account the demand for improving the processing capacity, and adopts the way of arranging multiple feeding pipes 100 side by side.

[0050] For example, the number of feeding pipes 100 can be 2, 3, 4, 5, 6, 7, 8, or 9, etc.

[0051] The arrangement of the feeding pipes 100 can also be linear arrangement, arc arrangement, etc.

[0052] Obviously, by increasing the number of feeding pipes 100, more materials can be processed at the same time, thereby significantly improving the processing capacity of the entire feeding device, that is, multiple packaging boxes can be fed at the same time. This is particularly important for production lines that require high productivity.

[0053] Of course, if a certain feeding pipe 100 fails, the other feeding pipes 100 can still work, reducing the production line downtime caused by equipment failure and enhancing the stability and reliability of the system.

[0054] In some embodiments, the valve member 300 comprises a plug 310 and a driving portion 320. The sidewall of the feeding tube 100 has a plug slot 110, which is in communication with the feeding tube 100. The plug 310 is inserted into the plug slot 110. The driving portion 320 is connected to the plug 310 and is capable of driving the plug 310 in and out of the feeding tube 100.

[0055] In these embodiments, the valve member 300 employs a combination of the plug 310 and the driving portion 320. The plug 310 is the key component that directly participates in the control of the material flow. The plug 310 is capable of moving laterally within the feeding tube 100 to cut off or allow the material to pass through.

[0056] The plug slot 110 is provided on the sidewall of the feeding tube 100 and is in communication with the interior of the feeding tube 100, allowing the plug 310 to be inserted therein. The plug slot 110 ensures that the plug 310 can smoothly enter and exit the feeding tube 100.

[0057] The driving portion 320 is connected to the plug 310 and is responsible for driving the plug 310 in and out of the feeding tube 100. The driving portion 320 can take various forms, such as pneumatic, electric, or mechanical drive, and the appropriate driving method is selected according to actual needs. For example, the driving portion 320 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0058] When it is necessary to cut off the material flow, the driving portion 320 drives the plug 310 into the feeding tube 100, thereby preventing the material from continuing to flow downward. This can form a physical barrier between any two temporary storage chambers 120, ensuring that the material is temporarily stored in the current temporary storage chamber 120.

[0059] When it is necessary to allow the material to continue to fall into the next temporary storage chamber 120 or to be finally released into the packaging box, the driving portion 320 pulls the plug 310 out of the feeding tube 100, so that the adjacent temporary storage chambers 120 are in a communication state, and the material can naturally flow under the action of gravity.

[0060] In some embodiments, all the feeding tubes 100 are arranged in an array in the first direction, and the plugs 310 at the same height are connected to the same driving portion 320.

[0061] In these embodiments, all the feeding tubes 100 are arranged in an array in the first direction (e.g., the horizontal direction), and all the plugs 310 at the same height are connected to the same driving portion 320.

[0062] By connecting all the inserts 310 at the same height to the same drive unit 320, the synchronized opening and closing actions of these inserts 310 can be achieved. This helps to ensure the consistency of material flow in each feeding tube 100, especially when handling the same material or performing the same operation at the same time.

[0063] Since multiple inserts 310 share one drive unit 320, the number of individual drive units 320 is reduced, simplifying the control system of the entire device. This not only reduces costs but also reduces failure points, improving system reliability and maintenance convenience.

[0064] The array layout makes the equipment more compact, effectively utilizing production space. Especially in situations where space is limited but high productivity is required, it maximizes production capacity per unit area.

[0065] In simple terms, all inserts 310 at the same height are arranged on a connecting frame, which is connected to the drive unit 320.

[0066] It should be noted that all feeding tubes 100 are arranged in the first direction array, so all the slots are on the same side, and all the inserts 310 are also on the same side.

[0067] In some embodiments, all inserts 310 at the same height are integrated.

[0068] In these embodiments, integrating all inserts 310 of the feeding tubes 100 at the same height is an optimized design. At the same height, all inserts 310 in the feeding tubes 100 are configured as a whole structure rather than individual components. This means that when the drive unit 320 is activated, this whole block of inserts 310 will simultaneously control the opening and closing actions of all related feeding tubes 100.

[0069] By combining multiple inserts 310 into one whole, the number of parts is reduced, simplifying the mechanical structure of the entire device. This not only reduces manufacturing costs but also may reduce the risk of equipment failure. The integrated inserts 310 can ensure that all associated feeding tubes 100 perform completely consistent operations at the same time, improving the synchronization and consistency of material flow, which is crucial for ensuring product quality and production efficiency.

[0070] Due to the reduction in the number of moving parts, integration can reduce maintenance requirements and, due to its more stable structure, provide longer service life and higher operational stability.

[0071] This design can also help optimize the internal space layout of the equipment, making the entire feeding device more compact and efficient, which is beneficial for adapting to limited production workshop space.

[0072] In some embodiments, the cross-section of the insert plate 310 and the feed tube 100 forms an angle, the insert plate 310 has an insertion end and a fixed end arranged oppositely, the fixed end is connected to the driving part 320, and the insertion end is used to penetrate into the insert plate slot 110, and the height of the insertion end is lower than that of the fixed end.

[0073] In these embodiments, the cross-section of the insert plate 310 and the feed tube 100 forms an angle, which can provide more effective material control and prevent material blockage.

[0074] The cross-section of the insert plate 310 and the feed tube 100 forms an angle, which means that the insert plate 310 is not installed vertically to the feed tube 100, but is inclined at an angle, which helps to reduce the possibility of material accumulation or accumulation around the insert plate 310, and promotes smooth flow of material.

[0075] The insert plate 310 has an insertion end and a fixed end arranged oppositely. The fixed end is connected to the driving part 320, and the insertion end is used to penetrate into the insert plate 310. In particular, the height of the insertion end is lower than that of the fixed end, that is, the insert plate 310 is inclined.

[0076] That is, by designing the insert plate slot 110 to have a certain inclination angle, the accumulation or jamming of material around the insert plate 310 can be effectively avoided, which is particularly important when dealing with materials that are prone to caking or have poor flowability.

[0077] This design allows the material to flow more naturally along the inclined side of the insert plate 310, rather than directly facing a vertical obstacle, thereby improving the flow path of the material in the entire feed tube 100 and improving overall efficiency.

[0078] For example, the angle between the insert plate 310 and the horizontal plane is 40°, 50°, 60°, 70°, or 80°, etc.

[0079] In some embodiments, the upper slot wall of the insert plate slot 110 is parallel to the insertion end.

[0080] In these embodiments, the insert plate slot 110 is further optimized, specifically, the upper slot wall of the insert plate slot 110 is parallel to the insertion end.

[0081] The upper slot wall of the insert plate slot 110 is parallel to the insertion end. This means that from the direction of the insert plate 310 into the insert plate slot 110, the top edge is parallel to the upper inner wall of the insert plate slot 110.

[0082] So that the material is not easy to accumulate at the entrance of the insert plate slot 110. The design of the parallel upper slot wall and the insertion end can help the material flow along the predetermined path, rather than stagnate around the insert plate 310, reducing the risk of blockage.

[0083] Exemplarily, in this embodiment, a gap can be provided between the upper slot wall of the plate slot and the insertion end. Of course, in other embodiments, the upper slot wall of the plate slot and the insertion end are in abutment.

[0084] In some embodiments, the feeding device further comprises a material detection member 200 arranged at the outlet end of the feeding pipe 100 for detecting the passing state of individual feeding materials and generating a corresponding feeding confirmation signal.

[0085] In these embodiments, the feeding device is further equipped with a material detection member 200 arranged at the outlet end of the feeding pipe 100 for detecting whether individual feeding materials (e.g. peanut packets) have successfully passed and generating a corresponding feeding confirmation signal. This design increases the intelligence and accuracy of the system, ensuring the successful execution of each feeding operation.

[0086] The material detection member 200 is a sensor or detection device installed at the outlet end of the feeding pipe 100, specifically for monitoring the passing state of the materials.

[0087] The detection member is located at the very end of the feeding pipe 100, i.e. the position where the materials are about to leave the feeding pipe 100 and enter the packaging box. Such an arrangement can accurately capture whether each material unit has successfully completed the feeding process.

[0088] Obviously, by monitoring the passing state of each material unit in real time, the material detection member 200 can effectively avoid the occurrence of missed feeding or re-feeding, improving the accuracy of feeding.

[0089] Once the successful passing of the materials is detected, the material detection member 200 generates a feeding confirmation signal. This signal can be used to trigger subsequent operations (such as the arm movement of the packaging machine) or as feedback information for the control system to analyze and record.

[0090] With the instant feedback provided by the material detection member 200, the production line can quickly discover and solve any potential problems, such as blockage or poor material flow, thereby ensuring the continuity and stability of production.

[0091] The collected feeding confirmation signals can also be used for production data statistics and analysis, helping enterprises better understand production efficiency, material usage, and equipment operating status, providing a basis for optimizing production processes.

[0092] Exemplarily, the material detection member 200 can be selected from the following types:

[0093] Optical sensor, which detects whether there is material passing by through emitting and receiving light beams.

[0094] Laser sensor, which uses a laser beam to scan the material passing area with high precision. High-end production lines with high requirements for material consistency. Need to identify whether the material is complete, damaged, etc.

[0095] Image recognition system, which takes pictures of the material falling process through a high-speed camera.

[0096] In some embodiments, the material detection member 200 includes a photoelectric sensor, which is arranged at the outlet end of the feeding pipe 100, and the detection area of the photoelectric sensor is located on the material falling path inside the feeding pipe 100.

[0097] In these embodiments, the material detection member 200 selects a photoelectric sensor and arranges it at the outlet end of the feeding pipe 100, and the detection area of the photoelectric sensor is located on the material falling path inside the feeding pipe 100. This design can efficiently and accurately monitor the material passing situation and generate a corresponding feeding confirmation signal.

[0098] A photoelectric sensor is a device that uses a light beam to detect the presence of an object. It usually consists of a transmitter and a receiver. The transmitter emits a beam of light (usually infrared). The receiver is responsible for detecting whether the beam of light is blocked or reflected back by an object.

[0099] The photoelectric sensor is installed at the outlet end of the feeding pipe 100, and its detection area accurately covers the path of the material falling from the feeding pipe 100. This means that when the material passes through, it will temporarily block or change the light path of the photoelectric sensor.

[0100] That is, when there is no material passing through, the receiver of the photoelectric sensor can receive the light beam emitted by the transmitter; once the material falls, this light path is temporarily blocked, and the receiver cannot receive the complete light signal.

[0101] Based on the above changes, the photoelectric sensor can identify that the material has passed and generate a feeding confirmation signal accordingly. This signal can be used to trigger subsequent operations or as feedback information for the control system.

[0102] In some embodiments, the present application also provides a feeding machine, which includes the feeding device according to any one of the above embodiments.

[0103] Since the above-mentioned feeding device has the above-mentioned technical effects, the feeding machine including the feeding device should have the same technical effects, which will not be described here.

[0104] In all examples shown and described here, any specific values should be interpreted as merely exemplary and not as limiting, therefore, other examples of exemplary embodiments can have different values.

[0105] It should be noted that like reference numerals and characters refer to like elements throughout the following figures and the text, such that when a figure is cited in this specification, subsequent figures can not be further defined and explained.

[0106] The above-described embodiments are merely illustrative of several embodiments of the present application, and the description is relatively specific and detailed, but should not be construed as limiting the scope of the present application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
