Description

Technical Field

[0001] The utility model belongs to the field of feeding equipment and relates to a vibrating feeder. Background Art

[0002] In industrial production, vibrating feeder has become an indispensable key equipment with its unique advantages and efficient and accurate material conveying capabilities. Its simple and sturdy structural design enables it to withstand a large amount of material handling needs, while running with low noise and low energy consumption. These features have contributed to its wide application in many industries such as mining, metallurgy, coal, glass, building materials, chemicals, electricity and food.

[0003] The main function of the vibrating feeder is to continuously and evenly transport the materials in the storage bin or hopper, whether they are in the form of blocks, granules or powder, to the receiving device. This stable material transportation method ensures the smooth progress of the production process and improves the overall production efficiency.

[0004] However, although vibrating feeders perform well in material conveying, they have certain limitations in controlling the feeding accuracy. Currently, vibrating feeders on the market are usually equipped with a movable baffle at the feeding port to adjust the flow of materials. Unfortunately, this design only provides two operating options: closed and open, and lacks more precise adjustment capabilities.

[0005] Therefore, in actual operation, when the material delivery reaches the preset value, even if the operator reacts quickly and closes the baffle, it is still difficult to prevent some materials from slipping out of the chute. This situation has a direct impact on the weight of the material on the weighing mechanism below, resulting in a significant reduction in the accuracy of the material weight.

[0006] In addition, the error caused by the impact force during the material falling process also has an adverse effect on the accuracy of the material weight. This impact error is superimposed on the inaccuracy of the baffle plate control, further weakening the control effect of the vibrating feeder in terms of overall material feeding accuracy. These problems not only affect the accuracy of production, but may also have a potential impact on product quality and production costs. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a vibrating feeder, aiming to improve the feeding accuracy of the feeder.

[0008] To achieve the above object, the present utility model provides a vibrating feeder. An inlet cylinder is provided at the upper end of the feeder body, and a feeding port is provided at the lower end. A baffle seat for changing the material flow direction of the feeding port is slidably provided at the edge of the feeding port, and the baffle seat is connected to a material buffer bin. A material passing hole is provided on the baffle seat; a material receiving port is provided at a position corresponding to the material passing hole in the material buffer bin, and a discharge port is provided at a position opposite to the material receiving port. A roller is rotatably provided in the material buffer bin, and material receiving grooves are provided on the side wall of the roller at positions corresponding to the material receiving port and the discharge port.

[0009] Materials enter the material receiving groove from the feeding port through the baffle seat. The rotation of the roller drives the material receiving groove to turn towards the feeding port, and the materials fall out from the discharge port due to their own gravity.

[0010] Optionally, a material receiving plate is provided at the bottom of the material receiving groove, and the material receiving plate is slidably provided on the groove wall of the material receiving groove.

[0011] Optionally, a rotary cylinder is provided at one end of the material buffer bin, and the output end of the rotary cylinder is connected to the roller.

[0012] Optionally, an adjusting rod is arranged in the roller in a way that it slides along the radial direction of the roller, and an adjusting component for adjusting the volume of the material receiving groove is provided on the adjusting rod. The adjusting component includes a first connecting block provided on the adjusting rod, a second connecting block provided on the material receiving plate, and a connecting rod connecting the first connecting block and the second connecting block. One end of the connecting rod is hinged to the first connecting block, and the other end is hinged to the second connecting block.

[0013] The first connecting block moves synchronously with the adjusting rod, driving the connecting rod to rotate relative to the first connecting block and the second connecting block, and pushing the second connecting block and the material receiving plate to slide in the material receiving groove, thereby covering the volume of the material receiving groove.

[0014] Optionally, a limiting block is provided in the middle of the adjusting rod to limit the displacement distance of the adjusting rod, thereby limiting the displacement distance of the material receiving plate, and further controlling the volume change range of the material receiving groove.

[0015] Optionally, an even number of adjusting components are provided on the adjusting rod, and every two adjusting components are symmetrically arranged on the adjusting rod.

[0016] Optionally, the adjusting components are grouped in pairs, and at least two groups of adjusting components are evenly distributed along the axial direction of the adjusting rod. Optionally, a telescopic cylinder is provided at one end of the material buffer bin opposite to the rotary cylinder, and the output end of the telescopic cylinder is connected to the adjusting rod.

[0017] Optionally, the two ends of the roller and the two ends of the material buffer bin are in sealed cooperation.

[0018] Optionally, the material receiving plate and the side wall of the material receiving groove are in sealed cooperation.

[0019] Optionally, a push frame is provided on one side of the material baffle seat, and the push frame is connected to the output shaft of the push cylinder.

[0020] The beneficial effects of the present utility model are as follows:

[0021] When the feeding amount of the vibrating feeder approaches the preset value, the material baffle seat moves and completely covers the feeding port, so that the material in the feeding port enters the material buffer bin through the material baffle seat. Then, by rotating the roller in the material buffer bin, the material is sent out in small amounts and batches through the discharge port of the material buffer bin until the feeding reaches the set weight. That is to say, the vibrating feeder provided by the present utility model can switch to the intermittent feeding mode when the feeding amount approaches the preset value. Coupled with the adjustable volume of the receiving groove in the material buffer bin, the feeding amount each time can be controlled, and finally the accuracy of the feeding weight can be improved. In addition, the intermittent feeding mode can also ignore the impact error caused by the large material weight, further improving the accuracy of the feeding weight.

It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] Among them, the drawings are only for illustrative purposes, showing only schematic diagrams rather than physical diagrams, and should not be construed as a limitation to the present utility model; in order to better illustrate the embodiments of the present utility model, some components in the drawings will be omitted, enlarged or reduced, which does not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0031] In the drawings of the embodiments of the present utility model, the same or similar reference numerals correspond to the same or similar components; in the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicating the orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only for illustrative purposes and should not be construed as a limitation to the present utility model. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] In order to improve the feeding accuracy of the feeder, the present utility model proposes a vibrating feeder, which mainly consists of a feeder body 1, a feeding hopper 2, a feeding port 17, a baffle seat 4, a material buffer bin 6 and a roller 12. The upper end of the feeder body 1 is equipped with a feeding hopper 2 for receiving materials, and the lower end is provided with a feeding port 17 for discharging materials. A slidable baffle seat 4 is installed at the edge of the feeding port 17 to change the material flow direction of the feeding port 17. A material passing hole (not shown in the figure) is opened on the baffle seat 4. The lower end of the baffle seat 4 is connected to a material buffer bin 6, and the baffle seat 4 and the material buffer bin 6 are communicated with each other. The material buffer bin 6 is provided with a material receiving port 18 at a position corresponding to the material passing hole, and a discharge port 19 is opened at a position opposite to the material receiving port 18. When the baffle seat 4 completely covers the feeding port 17, the material will smoothly flow into the material buffer bin 6 through the baffle seat 4 and flow out from the discharge port 19 of the material buffer bin 6.

[0033] Furthermore, a rotatable drum 12 is provided in the material buffer bin 6. Both ends of the drum 12 are sealingly fitted with both ends of the material buffer bin 6. For example, sealing flanges are provided at both ends of the drum 12 and both ends of the material buffer bin 6 to ensure the sealing performance inside the material buffer bin 6 and the drum 12. Receiving grooves 11 are formed at positions on the side wall of the drum 12 corresponding to the material receiving port 18 and the material discharging port 19, so as to receive and distribute materials. The materials flow from the feeding port 17 through the material blocking seat 4 into the receiving groove 11. The rotation of the drum 12 drives the receiving groove 11 to turn towards the feeding port 17, enabling the materials to accurately fall out from the discharging port 19 due to their own gravity.

[0034] When the feeding amount of the vibrating feeder approaches the preset value, the material blocking seat 4 moves and completely covers the feeding port 17, causing the materials in the feeding port 17 to enter the material buffer bin 6 through the material blocking seat 4. Then, by rotating the drum 12 in the material buffer bin 6, the materials are sent out in small amounts and in batches through the discharging port 19 of the material buffer bin 6 until the feeding reaches the set weight. Since the weight of the materials discharged through the discharging port 19 each time is relatively low, the intermittent feeding hardly generates impact errors caused by the weight of the materials, further improving the accuracy of the feeding weight.

[0035] Furthermore, in order to more precisely control the feeding amount of each intermittent feeding, a receiving plate 14 that slides along the groove wall of the receiving groove 11 is provided at the bottom of the receiving groove 11. The volume of the receiving groove 11 is flexibly adjusted through the displacement of the receiving plate 14, thereby controlling the amount of each feeding. In order to achieve the displacement control of the receiving plate 14, an adjusting rod 10 is slidably arranged in the drum 12 in the radial direction, and at least one adjusting component for adjusting the volume of the receiving groove is provided on the adjusting rod 10.

[0036] The adjusting component includes a first connecting block 13 provided on the adjusting rod 10 and a second connecting block 16 provided on the receiving plate 14. One end of the connecting rod 15 is rotatably connected to the first connecting block 13, and the other end is rotatably connected to the second connecting block 16. When the adjusting rod 10 moves, the first connecting block 13 will move accordingly, and the receiving plate 14 is pushed to slide in the receiving groove 11 through the connecting rod 15, thereby adjusting the volume of the receiving groove 11.

[0037] In some alternative embodiments, the number of adjusting components is even, and every two adjusting components are symmetrically arranged on the adjusting rod. Further, the adjusting components are grouped in pairs, and at least two groups of adjusting components are evenly distributed along the axial direction of the adjusting rod, so as to apply force to the receiving plate 14 more evenly when adjusting the volume of the receiving chute 11. Preferably, the number of the first connecting blocks 13 is preferably 4. Correspondingly, the number of the connecting rods 15 and the second connecting blocks 16 is 4 each. The first connecting blocks 13 are grouped in pairs, and the two groups of first connecting blocks 13 are respectively distributed at both ends of the adjusting rod 10 along the length direction. The first connecting blocks 13 within a group are symmetrically arranged on the adjusting rod 10 with the axis of the adjusting rod 10 as the axis of symmetry, and are respectively connected to the second connecting blocks 16 through their corresponding connecting rods 15. Thus, when the adjusting rod 10 moves, two receiving plates 14 can be simultaneously pushed, achieving the purpose of simultaneously adjusting the volumes of the two receiving chutes 11.

[0038] In some alternative embodiments, in order to drive the movements of the roller 12 and the adjusting rod 10, a rotary cylinder 7 is provided at one end of the material buffer bin 6, and its output end is connected to the roller 12 to control the rotation of the roller 12. And a telescopic cylinder 3 is provided at the other end of the material buffer bin 6, and its output end is connected to the adjusting rod 10 to control the movement of the adjusting rod 10.

[0039] In some alternative embodiments, the number of the first connecting blocks 13 is preferably even, and they are evenly distributed in pairs on the adjusting rod 10.

[0040] In some alternative embodiments, a limiting block 9 is provided in the middle of the adjusting rod 10 to limit the distance of the axial movement of the adjusting rod 10 along the roller 12, thereby limiting the adjustment range of the volume of the receiving chute 11.

[0041] In some alternative embodiments, the number of the first connecting blocks 13 is preferably even, and they are evenly distributed in pairs along the axial direction of the adjusting rod 10. The number of the second connecting blocks 16 is the same as that of the first connecting blocks 13, and their installation positions are staggered from those of the first connecting blocks 13, so that the first connecting blocks 13 can smoothly push the receiving plate 14 to move. The two first connecting blocks 13 within a group are symmetrically distributed with the axis of the adjusting rod 10 as the center, and are respectively connected to the receiving plates 14 corresponding to the positions of the receiving opening 18 and the discharging opening 19 through the connecting rods 15 and the second connecting blocks 16, so as to simultaneously adjust the volumes of the two receiving chutes 11 corresponding to the positions of the receiving opening 18 and the discharging opening 19.

[0042] In some alternative embodiments, a pushing frame 5 is provided on one side of the material retaining seat 4. The pushing frame 5 is connected to the output shaft of the pushing cylinder 8, and the pushing cylinder 8 pushes the material retaining seat 4 to move through the pushing frame 5, so that the feeding port 17 of the vibrating feeder is covered or exposed.

[0043] The working principle of the vibrating feeder provided by the present utility model is as follows:

[0044] When the feeding amount of the vibrating feeder approaches the preset value, the pushing cylinder 8 pushes the material blocking seat 4 close to the discharge port 19 until the material blocking seat 4 completely covers the discharge port 19. At this time, the materials in the vibrating feeder can only fall into the receiving groove 11 of the material buffer bin 6 near the material receiving port 18 through the material blocking seat 4. Then, the rotating cylinder 7 drives the roller 12 to rotate, and the roller 12 drives the receiving groove 11 and the materials therein to rotate 180 degrees, so that the receiving groove 11 is aligned with the discharge port 19 of the material buffer bin 6, and the materials fall onto the weighing mechanism from the discharge port 19 under the action of gravity. During the feeding process, the volume of the receiving groove 11 can be adjusted according to actual needs. The telescopic cylinder 3 pushes the adjusting rod 10 to move, thereby driving a plurality of first connecting blocks 13 to move along the axial direction of the roller 12. During this process, the connecting rod 15 pushes the second connecting block 16 and the connected receiving plate 14 to move in the receiving groove 11, thereby changing the volume of the receiving groove 11.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered by the scope of the claims of the present invention.
