Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding mechanisms, and more specifically, to an automatic feeding mechanism for a hopper. Background Technology
[0002] In the field of automated material and semi-finished product feeding, traditional feeding methods have many problems. Previous silo designs often did not fully consider space utilization efficiency, resulting in large silo occupancy and limiting the amount of material that can be stored in a limited space.
[0003] For some raw materials with protective coatings on their surfaces, traditional vibratory feeder feeding methods are not suitable, because the vibration of the vibratory feeder may damage the coating on the material surface and affect product quality.
[0004] In addition, the existing feeding devices are not very versatile and are difficult to use for materials of equal width and multiple lengths. This requires frequent replacement of feeding devices during production, which increases production and time costs.
[0005] Moreover, traditional feeding methods can easily scratch the surface of materials during the feeding process, thereby reducing the product qualification rate.
[0006] At the same time, some existing material supply equipment is expensive, and it is impossible to effectively control costs while meeting technical requirements, which brings certain economic pressure to enterprises.
[0007] In summary, existing material semi-finished product feeding technologies suffer from problems such as low space utilization, easy damage to material surfaces, poor versatility, and high costs. Therefore, we propose an automatic silo feeding mechanism to improve upon these limitations. Utility Model Content

It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] Example 1: Please refer to Figures 1-5An automatic feeding mechanism for a silo includes a silo base plate 1 and a mounting base plate 6. A front baffle 2 is provided on the lower front surface of the silo base plate 1, a grid plate 5 is provided on the front part of the silo base plate 1, a raised column 7 is provided on the upper end of the mounting base plate 6, a first inclined mounting plate 8 is provided on the upper end of the raised column 7, and a second inclined mounting plate 9 is provided on the upper end of the first inclined mounting plate 8.
[0034] Short material products 3 and long material products 4 are placed on the grid plate 5. Four supporting columns 7 are provided, and the four supporting columns 7 are respectively located at the four corners of the mounting base plate 6. The mounting base plate 6 is connected to the transfer screw module 10. A material arrival reflection sensor 11 is provided on the side of the grid plate 5. A groove 51 is opened on the grid plate 5. A push screw module 12 is provided diagonally below the grid plate 5, and the tilt angle of the hopper base plate 1 and the grid plate 5 is the same as that of the push screw module 12.
[0035] The silo bottom plate 1, the front baffle 2, the short material product 3, the long material product 4, the grid plate 5, the mounting base plate 6, the raised column 7, the first inclined mounting plate 8, and the second inclined mounting plate 9 are all installed on the transfer screw module 10.
[0036] The second inclined mounting plate 9 has a triangular structure, and the inclination angle of the inclined side of the second inclined mounting plate 9 is the same as the inclination angle of the hopper bottom plate 1, the grid plate 5, and the push screw module 12.
[0037] The transfer screw module 10 is installed statically and horizontally.
[0038] The transfer screw module 10 is equipped with a transfer screw motor, which is connected to the transfer screw. The transfer screw is equipped with a transfer sliding frame, which is connected to the mounting base plate 6. The movement of the mounting base plate 6 drives the hopper base plate 1, the front baffle 2, the short material product 3, the long material product 4, the grid plate 5, the mounting base plate 6, the raised column 7, the first inclined mounting plate 8, the second inclined mounting plate 9, and the transfer screw module 10 to move.
[0039] The lead screw module 12 is equipped with a lead screw motor, which is connected to the lead screw. The lead screw is connected to the push sliding frame, which is equipped with a push plate. The push plate pushes the short material product 3 or the long material product 4 for feeding.
[0040] The working principle of the automatic feeding mechanism of the hopper is as follows:
[0041] 1. Short material products 3 and long material products 4 are manually stacked sideways in a row and placed in the groove 51 of the grid plate 5. Since the bottom plate 1 of the silo, the grid plate 5 and the push screw module 12 all have a certain tilt angle, the materials are tightly bound together under the influence of gravity, which reduces the space occupied by the silo and increases the amount of material that can be accommodated.
[0042] 2. The transfer screw motor on the transfer screw module 10 starts, driving the transfer screw to rotate, thus moving the transfer sliding frame. The transfer sliding frame is connected to the mounting base plate 6, thereby driving the hopper base plate 1, front baffle 2, short material product 3, long material product 4, grid plate 5, mounting base plate 6, raised column 7, first inclined mounting plate 8, second inclined mounting plate 9, and the transfer screw module 10 to move the material to each grid 25mm of workstations 1-10, so that the push rod of the push screw module 12 is located in the center position of the corresponding grid plate 5.
[0043] 3. The motor on the lead screw module 12 starts, driving the lead screw to rotate and pushing the push plate on the sliding frame. The push plate pushes the short material product 3 or the long material product 4 for feeding.
[0044] 4. A material arrival reflection sensor 11 is installed on the side of the grid plate 5. During the inclined pushing process, when the sensor is reflected, it indicates that there is material and will give a signal. The next step is to notify the robot arm to grasp the material for the next process.
[0045] 5. After the robotic arm grabs the first piece of material, the sensor loses signal, and the push rod of the lead screw module 12 is pushed forward again, and so on, to complete the material replenishment.
[0046] The automatic feeding mechanism for this hopper was originally designed to address the issue of using vibratory feeders for raw materials with protective coatings on their surfaces. It boasts advantages such as small footprint, large material capacity, versatility, compatibility with various widths and lengths of materials, minimal risk of surface scratches, and extremely low cost.
[0047] The working process of the automatic feeding mechanism of the hopper is as follows:
[0048] 1. Initial preparation
[0049] The motor returns to zero.
[0050] Short material product 3 and long material product 4 are manually stacked sideways in a row and placed in the groove 51 of the grid plate 5. Gravity and the tilt angle of the silo bottom plate 1, grid plate 5 and push screw module 12 are used to make the materials tightly closed.
[0051] 2. Material transfer
[0052] The transfer screw motor on the transfer screw module 10 starts, driving the transfer screw to rotate, which in turn moves the transfer sliding frame.
[0053] The transfer sliding frame is connected to the mounting base plate 6, which drives the silo base plate 1, front baffle 2, short material product 3, long material product 4, grid plate 5, mounting base plate 6, raised column 7, first inclined mounting plate 8, second inclined mounting plate 9 and transfer screw module 10 to move horizontally as a whole.
[0054] Move 25mm to each grid of station 1-10 so that the push rod of the lead screw module 12 is centered in the corresponding grid panel 5.
[0055] 3. Materials advancement
[0056] The motor on the lead screw module 12 starts, driving the lead screw to rotate and pushing the sliding frame to move.
[0057] Push the push plate on the sliding frame to feed short material product 3 or long material product 4.
[0058] 4. Sensor detection and robotic gripping
[0059] During the material delivery process, the material arrival reflection sensor 11 on the side of the grating plate 5 uses the principle of reflection to detect whether there is material.
[0060] When the sensor detects material, it sends a signal to notify the robotic arm to grab the material and use it in the next process.
[0061] 5. Continuous material supply
[0062] After the robotic arm grabs the first piece of material, the sensor loses signal, and the push rod of the lead screw module 12 is pushed forward again. The above steps are repeated, and so on, to complete the continuous replenishment of materials.
[0063] Example 2: An automatic feeding mechanism for a hopper.
[0064] 1. Material preparation:
[0065] Prepare short material product 3 and long material product 4.
[0066] The materials are stacked on their sides in a row and manually placed in the groove 51 of the grid panel 5.
[0067] 2. Initial settings:
[0068] Ensure that the transfer screw module 10 is installed horizontally and stationary, and return the transfer screw motor to zero.
[0069] Confirm the position and status of the lead screw module 12 and place it in its initial position.
[0070] 3. Material transfer:
[0071] Start the transfer screw motor on the transfer screw module 10, and the motor will drive the transfer screw to rotate.
[0072] The transfer sliding frame on the transfer screw moves accordingly, and through its connection with the mounting base plate 6, it drives the entire silo structure, including the silo base plate 1, front baffle 2, short material products 3, long material products 4, grid plate 5, mounting base plate 6, raised column 7, first inclined mounting plate 8, second inclined mounting plate 9, and transfer screw module 10, to move horizontally.
[0073] Move to station 1 so that the push rod of the push screw module 12 is in the center of the corresponding grid plate 5. At this time, the material inside the grid plate 5 is tightly closed under the action of gravity and slope.
[0074] 4. Materials Development:
[0075] Start the lead screw motor on the lead screw module 12, and the motor drives the lead screw to rotate.
[0076] The lead screw pushes the sliding frame, causing the push plate on the sliding frame to push the short material product 3 or the long material product 4 for feeding.
[0077] 5. Sensor detection and robotic gripping:
[0078] During the material delivery process, the material arrival reflection sensor 11 on the side of the grating plate 5 uses the principle of reflection to detect whether there is material.
[0079] When the sensor detects material, it sends a signal to notify the robotic arm to grasp it.
[0080] The robotic arm picks up the first piece of material and moves it to the next step of the process.
[0081] 6. Continuous material supply:
[0082] After the robotic arm grabs the material, the sensor detects that there is no material at that position, and the push rod of the lead screw module 12 is pushed forward again to push the next material to the position to be grabbed.
[0083] Repeat the above steps to push and grab materials in workstations 1-10 in sequence to complete the continuous replenishment of materials.
[0084] In this embodiment, the automatic feeding mechanism of the hopper fully leverages its advantages of small footprint, large material capacity, high versatility, resistance to surface scratches from materials, and extremely low cost, effectively realizing the automatic feeding of semi-finished materials and improving production efficiency and product quality.
