Description

Technical Field

[0001] The present invention relates to the technical field of automatic feeding, and specifically provides an automatic feeding device for raisin processing. Background Art

[0002] During the production and processing of raisins, multiple processes such as screening and grading, cleaning, drying, and packaging are required. The traditional processing method of manual cooperation with equipment has low efficiency and is difficult to ensure product consistency and hygiene and safety standards. To improve the standardization of raisin production and processing, automatic raisin production lines are widely used. In multiple production processes of the automatic raisin production line, an automatic feeding device is required for feeding. Among them, the automatic feeding device needs to perform multiple processes such as screening and grading, cleaning, drying, and packaging of raisins during the feeding process.

[0003] However, during the use of the existing automatic feeding device in the screening and grading process, most of them need to cooperate with a separation mechanism to separate the agglomerated raisins, and then use a vibrating screen mechanism to grade the raisins of different specifications and sizes. Then, it cooperates with a conveyor belt mechanism to complete the feeding of the next process. When the vibrating screen mechanism screens raisins, most of them use a single mechanical movement such as a screen combined with high-frequency vibration or swinging and shaking to complete the separation of raisins, resulting in a large difference in the uniformity of raisin grading during the screening and grading process. On the other hand, the screening and grading of a single high-frequency vibration or swinging and shaking mechanism requires a long working surface, resulting in a large volume of the vibrating screen mechanism and the separation mechanism, which is inconvenient for subsequent maintenance and installation. When separating and screening raisins of different volumes, it is necessary to adjust the equipment one by one, resulting in frequent operations during the production process and affecting the production and processing efficiency. Summary of the Invention

[0008] Preferably, the two rotating columns and the two tooth columns are installed in opposite inclinations. The inner tooth openings of the internal gear ring are designed to be inclined. The inclination angle of the inner tooth openings of the internal gear ring corresponds to the inclination angle of the tooth columns. On the outer circumference of the two rotating columns, a plurality of soft body convex columns are fixedly arranged at equal intervals for the separation and feeding of adhered raisins.

[0009] Preferably, the top of the adjustment ring one is designed as a wave-shaped curved surface for the circumferential wave-shaped inclination of the installation plate. The adjustment ring two is designed as a tooth segment structure for the vibration of the installation plate.

[0010] Preferably, the lower end of the connecting column is designed as a sphere. The central groove of the connecting frame coincides with the sphere at the lower end of the connecting column. The sphere at the lower end of the connecting column is used for the circumferential inclined movement of the connecting frame. The circular convex column inside the opening of the connecting frame is in movable cooperation with the sliding groove outside the sphere at the lower end of the connecting column.

[0011] Preferably, the diameter of the sieve plate is smaller than the diameter of the movable groove. The position of the circular opening on the sieve plate deviates from the circular position of the sieve plate. The circular opening of the sieve plate is larger than the diameter of the central column of the limiting rod. The circular shape of the central column of the limiting rod corresponds to the center position of the mounting plate. The limiting rod lifts the sieve plate through the convex disk on the outer side of the bottom.

[0016] In the present invention, by setting the rotating frame to drive the inner gear ring and the external gear ring to rotate, and cooperating with the transmission assembly to abut and link with the first adjusting ring and the second adjusting ring, the mounting plate and the connecting frame are realized to swing and vibrate circumferentially around the connecting column. Cooperating with the sieve plate and the second material baffle to complete the screening and grading feeding of raisins of different sizes, the problem of insufficient screening and grading of raisins caused by the single vibration or swing of the screen screening device in the traditional feeding process is optimized. At the same time, cooperating with the connection structure of the sieve plate and the limiting rod, when the mounting plate swings circumferentially, the circular opening of the sieve plate fits and rotates with the central column of the limiting rod, and at the same time slides circumferentially in the movable groove. When the raisins roll circumferentially and vibrate and undulate for screening, the sieve plate adjusts its circumferential position by itself, further improving the effect of grading and screening and feeding the raisins.

[0017] In the present invention, by setting a rotating frame to drive the inner gear ring and the outer gear ring to rotate, and cooperating with the linkage between the tooth columns, the two rotating columns rotate in opposite directions, and the operation of separating and feeding the agglomerated raisins is carried out. At the same time, the laser sensor in the feeding hood monitors the volume and height of the raisins in the feeding hood in real time, and the controller system adjusts the corresponding positions of the upper slider and the sliding plate, so as to complete the circumferential shaking and vibration of the corresponding angle of the mounting plate, and complete the adaptive shaking amplitude adjustment during the circumferential wave-like undulating shaking screening and grading feeding in the feeding device, simplifying the operation in the process of the automatic raisin feeding device and improving the production efficiency.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 13, the present invention provides a technical solution: an automatic feeding device for raisin processing, including a frame 1. Inside the frame 1, conveyor belt mechanisms 2 are installed in an upper and lower staggered manner. At the top right of the frame 1, two fixing brackets 3 are installed.

The transmission component 7 includes a sliding shell 71. The sliding shell 71 is fixed inside the external gear ring 52. At the lower section inside the sliding shell 71, a lower sliding block 72 is slidably arranged. The lower end of the lower sliding block 72 abuts against the adjustment ring 81. The top of the lower sliding block 72 is slidably connected to an upper sliding block 73 through an electric push rod. On the inward side of the upper sliding block 73, a first sliding groove 74 is opened. Inside the first sliding groove 74, a first sliding block 75 is slidably arranged. The tops of the upper sliding block 73 and the first sliding block 75 abut against the installation plate 15. The inward convex block of the first sliding block 75 is connected to a sliding piece 76 through an electric push rod. The lower end of the sliding piece 76 abuts against the adjustment ring 82. The bottom surfaces of the upper sliding block 73 and the sliding piece 76 are both designed as arcs. The bottom arcs of the upper sliding block 73 and the sliding piece 76 are respectively used for sliding on the adjustment ring 81 and the adjustment ring 82. The adjustment ring 81 is installed and connected to the frame 1 through brackets on the front and rear sides. The adjustment ring 82 is fixed inside the adjustment ring 81. The top of the adjustment ring 81 is designed as a wave-shaped curved surface. The wave-shaped curved surface at the top of the adjustment ring 81 is used for the circumferential wave-like inclination of the installation plate 15. The adjustment ring 82 is designed as a tooth segment structure. The tooth segment structure of the adjustment ring 82 is used for the vibration of the installation plate 15. The lower ends of the two fixing brackets 3 are connected to an installation frame 9. Inside the installation frame 9, two rotating columns 10 are rotatably connected through bearings. At the tops of the two rotating columns 10, tooth columns 11 are fixed. The outer ends of the tooth columns 11 are meshed with the internal gear ring 51. The two rotating columns 10 and the two tooth columns 11 are installed in opposite inclinations. The inner tooth openings of the internal gear ring 51 are inclinedly designed. The inclination angle of the inner tooth openings of the internal gear ring 51 corresponds to the inclination angle of the tooth columns 11. A plurality of soft convex columns are fixedly arranged at equal circumferential intervals on the outer sides of the two rotating columns 10. The soft convex columns on the outer sides of the two rotating columns 10 are used for the separation and feeding of adhered raisins. A first material blocking cover 12 is sleeved outside the installation frame 9. A connecting column 13 is fixed at the lower end of the installation frame 9. A connecting frame 14 is circumferentially movably connected to the outside of the connecting column 13. The lower end of the connecting column 13 is designed as a sphere. The central groove of the connecting frame 14 fits with the sphere at the lower end of the connecting column 13. The sphere at the lower end of the connecting column 13 is used for the circumferential inclined movement of the connecting frame 14. The circular convex column inside the opening of the connecting frame 14 is in movable cooperation with the sliding groove on the outside of the sphere at the lower end of the connecting column 13. The sliding groove on the outside of the sphere at the lower end of the connecting column 13 is used for the rotation limit of the connecting frame 14. The installation plate 15 is fixed at the lower end of the connecting frame 14. An activity groove 16 is opened inside the installation plate 15. Inside the activity groove 16, a sieve plate 17 is circumferentially slidably connected. Inside the circular opening at the top of the sieve plate 17, a limiting rod 18 is movably connected.The diameter of the sieve plate 17 is smaller than that of the movable groove 16. The position of the circular opening on the sieve plate 17 deviates from the circular position of the sieve plate 17. The circular opening of the sieve plate 17 is larger than the diameter of the central column of the limit rod 18. The circle of the central column of the limit rod 18 corresponds to the center position of the mounting plate 15. The limit rod 18 lifts the sieve plate 17 through the convex disc on the outer side of the bottom. The limit rod 18 is connected with a second material blocking cover 19 through the top rod body. The second material blocking cover 19 is fixed at the inner edge of the top of the mounting plate 15. A first discharge cover 20 is installed at the outer edge of the top of the mounting plate 15. A second discharge cover 21 is fixed at the inner edge of the bottom of the mounting plate 15; There are holes under the second material blocking cover 19. The holes under the second material blocking cover 19 are used for the raisins to roll out. The right gap of the first discharge cover 20 is used for the raisins to discharge to the right. The inner side of the second discharge cover 21 is designed as an inclined surface. The inclined surface of the second discharge cover 21 is used for the raisins to discharge to the left. The diameter of the second material blocking cover 19 is larger than that of the first material blocking cover 12;

[0035] When screening and grading raisins, the rotating frame 5 drives the inner gear ring 51 and the outer gear ring 52 to rotate, drives the lower slider 72, the upper slider 73, the first slider 75 and the sliding piece 76 to rotate synchronously through the sliding shell 71, so that when the lower slider 72 rotates, it touches the wave-shaped surface of the first adjusting ring 81, drives the upper slider 73 to contact the mounting plate 15 and the connecting frame 14 in a wave-shaped up and down manner, so that the mounting plate 15 and the connecting frame 14 fluctuate in a circumferential wave shape around the connecting column 13. At the same time, when the first slider 75 and the sliding piece 76 rotate, after the sliding piece 76 touches the tooth opening on the second adjusting ring 82, it drives the first slider 75 to slide up and down rapidly in the first sliding groove 74, and rapidly reciprocates and knocks the mounting plate 15 through the upper end of the first slider 75, so that the raisins on the sieve plate 17 roll due to circumferential shaking, and cooperate with the vibration and fluctuation to facilitate the screening and grading of raisins of different sizes by the sieve plate 17;

[0036] During the circumferential shaking of the mounting plate 15, since the circular opening at the connection position between the sieve plate 17 and the limit rod 18 is opened deviating from the center of the circle, when the mounting plate 15 shakes circumferentially, when one side is lifted upward, the side with the longest distance between the edge of the sieve plate 17 and the circular opening always slides and adjusts in the inclined direction of the mounting plate 15 due to uneven position center of gravity, so that when the mounting plate 15 shakes circumferentially, the circular opening of the sieve plate 17 fits and rotates with the central column of the limit rod 18, and at the same time slides circumferentially in the movable groove 16, so that when the sieve plate 17 rolls and vibrates with the raisins, the sieve plate 17 itself makes a circumferential position adjustment, further improving the grading and screening and feeding effect of the raisins.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, please refer to Figures 1 to 13, including a frame 1, a conveyor belt mechanism 2 is installed vertically and staggeredly inside the frame 1. At the top right of the frame 1, two fixing brackets 3 are installed. At the upper ends of the two fixing brackets 3, a feeding cover 4 is fixed. At the top left of the frame 1, an opening is made and rotatably connected to a rotating frame 5 through a bearing. Inside the top of the rotating frame 5, an internal gear ring 51 is fixed. At the lower ends of the two fixing brackets 3, an installation frame 9 is connected. Inside the installation frame 9, two rotating columns 10 are rotatably connected through bearings. At the tops of the two rotating columns 10, a tooth column 11 is fixed. The outer end of the tooth column 11 meshes with the internal gear ring 51. At the bottom of the rotating frame 5, an external gear ring 52 is connected. The outer end of the external gear ring 52 is meshed with a gear disk 6. The gear disk 6 is installed on the rear side of the frame 1 through a motor. Inside the external gear ring 52, an installation plate 15, an adjusting ring 81 and an adjusting ring 82 are connected through a transmission component 7. The transmission component 7 includes a sliding shell 71. The sliding shell 71 is fixed inside the external gear ring 52. A lower sliding block 72 is slidably arranged in the lower section inside the sliding shell 71. The lower end of the lower sliding block 72 abuts against the adjusting ring 81. The top of the lower sliding block 72 is slidably connected to an upper sliding block 73 through an electric push rod. On the inner side of the upper sliding block 73, a first sliding groove 74 is opened. Inside the first sliding groove 74, a first sliding block 75 is slidably arranged. The tops of the upper sliding block 73 and the first sliding block 75 abut against the installation plate 15. The inner convex block of the first sliding block 75 is connected to a sliding piece 76 through an electric push rod. The lower end of the sliding piece 76 abuts against the adjusting ring 82. The bottom surfaces of the upper sliding block 73 and the sliding piece 76 are both designed to be arc-shaped. The bottom arc surfaces of the upper sliding block 73 and the sliding piece 76 are respectively used to slide on the adjusting ring 81 and the adjusting ring 82. The adjusting ring 81 is installed and connected to the frame 1 through brackets on the front and back sides. The adjusting ring 82 is fixed inside the adjusting ring 81. The top of the adjusting ring 81 is designed as a wave-shaped curved surface. The wave-shaped curved surface at the top of the adjusting ring 81 is used for the circumferential wave-shaped inclination of the installation plate 15. The adjusting ring 82 is designed as a tooth segment structure. The tooth segment structure of the adjusting ring 82 is used for the vibration of the installation plate 15;

[0039] Before screening and grading raisins, the motor drives the gear disk 6 and the external gear ring 52 to rotate, so that the rotating frame 5 rotates within the opening at the top of the frame 1. At the same time, the rotation of the rotating frame 5 drives the two tooth columns 11 and the two rotating columns 10 to rotate synchronously and in opposite directions within the installation frame 9 through the internal gear ring 51. During the rotation of the two rotating columns 10, the clumped raisins are dispersed and separated by the soft convex columns on the outer sides of the two rotating columns 10.

[0040] During the screening and grading process, the laser sensor in the feed hopper 4 monitors the volume height of raisins in the feed hopper 4 in real time, and the controller system activates the electric push rods connected to the upper slider 73 and the sliding piece 76. According to the volume height of raisins in the feed hopper 4, the upper slider 73 is adjusted upward to the corresponding position in the sliding housing 71, and at the same time, the sliding piece 76 is adjusted downward for corresponding adjustment. When the raisins are fed downward from the feed hopper 4, through the monitoring of the laser sensor in the feed hopper 4, the positions of the upper slider 73 and the sliding piece 76 are adjusted correspondingly in real time, and the angle of the circumferential wave-like undulation and shaking of the mounting plate 15 is adaptively adjusted to improve the uniformity of screening, grading, and feeding of raisins of different volumes.

[0041] Working principle: When using this automated feeding device for raisin processing, first, the operator activates the motor connected to the toothed disc 6, and then pours the raisins to be processed into the feed hopper 4. After the laser sensor in the feed hopper 4 detects the volume height of the raisins in the feed hopper 4, the controller system activates the electric push rods connected to the upper slider 73 and the sliding piece 76. According to the volume height of raisins in the feed hopper 4, the upper slider 73 is adjusted upward to the corresponding position in the sliding housing 71, and at the same time, the sliding piece 76 is adjusted downward for corresponding adjustment. When the raisins are fed downward from the feed hopper 4, through the monitoring of the laser sensor in the feed hopper 4, the positions of the upper slider 73 and the sliding piece 76 are adjusted correspondingly in real time;

[0042] When the raisins in the feed hopper 4 are fed, the motor drives the toothed disc 6 and the external toothed ring 52 to rotate, causing the rotating frame 5 to rotate within the top opening of the frame 1. At the same time, as the rotating frame 5 rotates, it drives the two toothed columns 11 and the two rotating columns 10 to rotate synchronously and in opposite directions within the mounting frame 9 through the internal toothed ring 51. During the rotation of the two rotating columns 10, the clumped raisins are separated and dispersed by the soft convex columns on the outer sides of the two rotating columns 10, completing the separation and feeding operation of the adhered and clumped raisins;

[0043] When the raisins pass through the two rotating columns 10 and enter between the upper material blocking cover 19 and the sieve plate 17 of the mounting plate 15, the rotating outer gear ring 52 drives the lower slider 72, the upper slider 73, the No. 1 slider 75 and the slide plate 76 to rotate synchronously through the sliding shell 71, so that when the lower slider 72 rotates, it conflicts with the wave-band curved surface of the adjusting ring 1 81, driving the upper slider 73 to fluctuate up and down in a wave-band manner to conflict with the mounting plate 15 and the connecting frame 14, so that the mounting plate 15 and the connecting frame 14 fluctuate in a circumferential wave-band manner on the connecting column 13. At the same time, when the No. 1 slider 75 and the slide plate 76 rotate, the slide plate 76 conflicts with the teeth on the adjusting ring 2 82, driving the No. 1 slider 75 to quickly move up and down in the No. 1 slide groove 74. The raisins on the sieve plate 17 are rolled due to the circumferential shaking, and the sieve plate 17 is convenient for screening and grading raisins of different sizes with the vibration fluctuation. In this process, the raisins screened by the sieve plate 17 are guided by the discharge cover 21 and fall onto the conveyor belt mechanism 2 on the upper left side. During the circumferential shaking of the mounting plate 15, the raisins between the discharge cover 1 20 and the material blocking cover 19 are entered through the opening below the material blocking cover 19, and fall into the conveyor belt mechanism 2 on the lower right side through the notch on the right side of the discharge cover 20, and enter the next processing link through the conveyor belt mechanism 2.

[0044] In the above process, when the mounting plate 15 oscillates circumferentially, the circular opening at the connection position of the sieve plate 17 and the limiting rod 18 is opened off the center of the circle, so that when the mounting plate 15 oscillates circumferentially, when one side is lifted upward, the side at the longest distance between the edge of the sieve plate 17 and the circular opening is always slid and adjusted in the tilting direction of the mounting plate 15 due to the uneven position of the center of gravity, so that when the mounting plate 15 oscillates circumferentially, the circular opening of the sieve plate 17 fits the center column of the limiting rod 18 and rotates, and at the same time slides circumferentially in the movable groove 16, so that when the raisins roll and vibrate, the sieve plate 17 itself adjusts its circumferential position, thereby further improving the grading, screening and feeding effect of the raisins.
