Description

Technical Field

[0001] This utility model relates to a rotating disc, and more particularly to a rotating disc structure and a feeder. Background Technology

[0002] The homogenizing disc feeder is an advanced feeding device with advantages such as uniform feeding, wide material adaptability, first-in-first-out material, stable and reliable operation, and reduced silo height. It is widely used in various fields. However, the existing homogenizing disc feeders have the following defects: (1) The turntable is designed with a flat bottom, and the blade pushes the material around the perimeter poorly, resulting in high resistance and energy consumption; (2) In order to ensure the overall rigidity of the blade, the blade plate is thick, which increases the weight of the equipment, increases the assembly difficulty, and increases the manufacturing cost; (3) The side area of ​​the blade plate is large, which generates high resistance when rotating, resulting in increased energy consumption and thus increasing the operating cost of the equipment; (4) When the material load is too large, the tail end of the blade is prone to deformation, the deflection increases, there is a risk of scraping the wall, and the rotation resistance increases, further increasing the energy consumption and operating cost; (5) When there is a lot of material on the blade surface, it is easy to cause material residue, which affects the working efficiency and increases the rotation resistance.

[0003] Therefore, this application urgently needs to design a novel turntable structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a turntable structure and feeder with low material cost and operating cost, low resistance and energy consumption, and good material pushing effect.

[0005] The technical solution of this utility model is:

[0006] One type of turntable structure of this utility model includes a support base, a support plate connected to the support base, and a sweeping plate connected to the support plate; multiple branches extend from the support plate, and the end of each branch is connected to the sweeping plate to form multiple blade structures; the blades are thinner along the direction from the support plate to the sweeping plate and are curved upwards.

[0007] Furthermore, each branch of the support plate is integrally formed or separately connected to the sweeping plate to form a paddle; the sweeping plate is designed with an upward-curving structure.

[0008] Furthermore, the branches of the support plate and the sweeping plate achieve a gradual reduction in thickness through a stepped structure or inclined surface design.

[0009] Furthermore, the support disk has a cross-shaped structure, forming four branches, and the ends of the four branches are respectively connected to a sweeping plate, thus forming a four-blade structure.

[0010] Furthermore, the angle between the sweeping plate and the horizontal plane is 0.3-0.8°.

[0011] Furthermore, a blade is connected to the bottom surface of the blade's end.

[0012] Furthermore, the transfer disc also includes a material separating ring, the inner circumference of which is arranged with several angled material separating teeth; the blade is located between adjacent material separating teeth and has the same thickness as the material separating teeth.

[0013] Furthermore, the outer periphery of the material separating ring is provided with several outwardly extending protrusions, the protrusions extending in the opposite direction to the material separating teeth, and grooves are formed between adjacent protrusions; an outer ring is also connected to the material separating ring, the outer ring extending upward along the material separating ring to form a retaining edge; the outer ring is provided with an insertion hole at a position corresponding to the sweeping plate for receiving the insertion of the end of the sweeping plate.

[0014] One type of feeder of the present invention includes a turntable structure according to any one of the preceding claims.

[0015] Furthermore, the feeder includes a frame and a cylinder; the cylinder includes an outer cylinder and an inner cylinder for containing materials; a discharge channel is provided below the inner cylinder, a turntable is provided below the discharge channel, and a base is provided below the turntable; a support seat of the turntable is connected to a drive motor via a drive shaft, the base passes through the drive shaft and is fixed to the frame, and a discharge port is provided on the base; an arch-breaking tip is provided at the top of the support seat; the blades extend into the outer cylinder, and the blades correspond to the discharge port; the material can flow along the discharge channel to the outer cylinder under the stirring of the turntable, and be discharged through the discharge port of the base.

[0016] Furthermore, the chassis has a higher center and a lower outer perimeter, forming a circular stepped structure.

[0017] The beneficial effects of this utility model are:

[0018] (1) Existing turntables are usually horizontal structures. In this embodiment, the sweeping plate is designed as an upward-curving structure, that is, the entire blade forms an upward-curving structure. On the one hand, the pushing capacity of the sweeping plate remains unchanged. When the equipment is full of material, some material will press onto the turntable, causing the turntable to deform downward under force. The greater the deformation is the further away from the center of the turntable, the more the upward-curving structure can offset some of the deformation displacement, ensure the gap between the turntable and the chassis, avoid the phenomenon of "scraping the bottom" and increased load, and make the equipment run stably. On the other hand, the width of the sweeping plate and the support plate can be effectively reduced, thereby reducing material costs, reducing the contact area between the turntable and the material, thereby reducing contact friction, and correspondingly reducing energy consumption. At the same time, the material accumulated on the blade is reduced, which can reduce material residue.

[0019] (2) The blades are made thinner and thinner. On the one hand, while ensuring the overall rigidity, it can also save material costs, reduce weight and energy consumption. On the other hand, it can reduce the cross-section of the turntable and reduce the pushing area of ​​the turntable during rotation, thereby reducing resistance and energy consumption, and further saving operating costs.

[0020] (3) By arranging the material separation teeth on the inner circumference of the material separation ring and setting the material separation teeth at a certain angle, the working load is reduced and the accumulation of residual material on the blade is reduced.

[0021] (4) By setting an annular groove on the outer periphery of the material separating ring, the gap between the material separating ring and the outer cylinder wall is increased. When the turntable is running, the material in the gap is subjected to less extrusion pressure, and the internal friction of the material in that place is also reduced, thereby reducing the turntable resistance and energy consumption. The material in the gap can fall to the bottom plate through the groove, and the protrusion between two adjacent grooves can push the material to the discharge port, so that there is less residual material on the turntable.

[0022] (5) When the feeder is running, the material moves from the middle to the outer perimeter. Through the circular step structure of the chassis, the material has a "downhill" phenomenon, which effectively reduces the material flow resistance and equipment energy consumption.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown: A feeder includes a frame 1, a cylinder 2, a lifting mechanism 3, an adjusting ring 4, a turntable 5, a base 6, and a drive motor 7. Specifically, the cylinder 2 includes an inner cylinder 21 for containing materials and an outer cylinder 22 for connecting the lifting mechanism 3. The inner cylinder 21 is connected to a hopper via an upper flange 8. At least three sets of lifting mechanisms 3 are evenly distributed circumferentially on the outer cylinder 22, and the lifting mechanism 3 is connected to the adjusting ring 4. A drive base 9 is provided on the frame 1, and the drive motor 7 is supported on the drive base 9. The drive motor 7 is connected to the turntable 5 via a drive shaft. The base 6 is provided below the turntable 5. The base 6 passes through the drive shaft and is fixed to the frame 1. The base 6 is provided with a discharge port 61.

[0031] More specifically, the outer cylinder 22 is bolted to the base plate 6 via the outer cylinder flange 10; the outer cylinder 22 is connected to the upper middle part of the inner cylinder 21, and the upper flange 8 at the upper end of the inner cylinder is exposed for connecting the hopper. The lower part of the inner cylinder 22 is suspended, with a certain gap between it and the turntable 5 located below it, which forms the discharge channel 23. The adjusting ring 4 is located inside the outer cylinder 22 and surrounds the outer periphery of the discharge channel 23. The lower end of the adjusting ring 4 extends downward along the discharge channel 23, maintaining a certain gap with the turntable 8 below it. There is also a gap between the turntable 5 and the base plate 6 located below it, and both ends of the base plate 6 extend towards the outer cylinder. The discharge port 61 of the base plate is located at the outer cylinder 22. The drive shaft is sealed to the base plate 6 and the turntable 5. The drive shaft is rotated by the drive motor 7, which in turn rotates the turntable 5. The material in the inner cylinder 21 can flow along the discharge channel 23 to the outer cylinder 22 under the stirring of the turntable 5, and is discharged through the discharge port 61 of the base plate. The adjusting ring 4 is controlled by the lifting mechanism 3 to adjust the discharge gap of the discharge channel 23, so as to ensure that the material is discharged evenly and continuously at the discharge port 61.

[0032] like Figures 2-3 As shown: In this embodiment, the turntable 5 includes an outer ring 51, blades 52, a sweeping plate 53, a support plate 54, a support base 55, and a material separating ring 56. The support base 55 has a puncture tip 57 at its top, which can be used to puncture the packaging bags inside the hopper, allowing the material to enter the cylinder. Preferably, the puncture tip 57 is welded to the support base 55 as a single unit.

[0033] The specific connection structure of the turntable 5 is as follows: the lower end of the support base 55 is connected to the support plate 54. The support plate 54 has a central hole that communicates with the inner cavity of the support base, allowing the drive shaft to enter the support base 55 through the central hole of the support plate 54 and form a sealed connection with the support base 55. The support plate 54 has a cross-shaped structure, forming four branches. The ends of the four branches are respectively connected to the sweeping plates 53, thus forming four paddle structures. The size of the support plate 54 gradually decreases from the center to the ends, that is, the size of the support plate 54 decreases from thick to thin to the sweeping plates 53, forming a stepped structure or slope. Through mechanical analysis, it can be seen that this design ensures a reasonable match between the overall rigidity of the turntable 5 and the plate thickness. That is, by adjusting the thickness distribution of the support plate 54, it has the rigidity required by the overall structure when under stress, and the weight of the turntable 5 is effectively reduced, saving material costs. Meanwhile, the design of turntable 5 optimizes its cross-section, reduces the physical size of the turntable, and reduces the pushing area of ​​turntable 5 during rotation, thereby reducing resistance and energy consumption, and further saving operating costs.

[0034] Furthermore, the sweeping plate 53 is designed with an upward-curving structure, meaning that the sweeping plate 53 forms an angle A° with the horizontal plane. Due to the weight of the turntable 5 and the pressure exerted by the material on the sweeping plate 53 and the support plate 54, the sweeping plate 53 is prone to downward deformation, and the further away from the support base 55, the greater the deformation deflection. In this case, the upward-curving angle of the sweeping plate 53 will decrease, thereby ensuring the gap between it and the chassis 6, avoiding the "bottom scraping" phenomenon or increased load, and thus maintaining the stable operation of the equipment. In addition, the upward-curving structure design of the sweeping plate 103 can effectively reduce the width of the sweeping plate 53 and the support plate 54, thereby reducing material costs, reducing the contact area between the turntable 5 and the material, thereby reducing contact friction and correspondingly reducing energy consumption, while reducing the amount of material accumulated on the blades, which can reduce material residue. The angle A° is determined based on the weight of the material in the hopper; the greater the weight, the larger the value of A. In this embodiment, the angle A° is preferably 0.5-0.6°. In this embodiment, to facilitate the design of the sweeping plate 53 as an upward-curving structure, it is preferable to design the four branch ends of the support plate 54 and the connecting end of the sweeping plate 53 as a structure with sloping sides and a pointed center. The sweeping plate 53 and the branch ends of the support plate 54 are joined at the pointed ends, making the sweeping plate 53 upward-curving. The joining method can be welding, riveting, etc., with welding being preferred.

[0035] Understandably, the upward-curving structure of the sweeping plate 53 can also be designed as an upward-curving arc tangent to the horizontal plane.

[0036] It is understandable that the sweeping plate 53 and the support plate 54 can also be designed as an integral structure, and have a stepped structure or slope to achieve a transition from thick to thin; and form an upward arc tangent to the horizontal plane.

[0037] Furthermore, the sweeping plate 53 is connected to the outer ring 51 at the end furthest from the support plate 54 (i.e., the end end), and is connected to the separating ring 56. Specifically, the outer ring 51 extends upward along the separating ring 56 to form a retaining edge, and the outer ring 51 is welded to the outer periphery of the upper surface of the separating ring 56; the outer ring 51 has an insertion hole 511 at a position corresponding to the sweeping plate 53 for inserting the end of the sweeping plate 53, the end of the sweeping plate 53 is inserted into the insertion hole 511 and overlaps the upper surface of the separating ring 56, and is welded to the separating ring 56 as a whole. The inner circumference of the separating ring 56 has several separating teeth 561 arranged circumferentially, which effectively separate and guide the flow of material through contact with the material. The separating teeth 561 are set with a certain inclination angle, thereby reducing the workload and reducing the accumulation of residual material on the blades. The outer circumference of the material separating ring 56 has several outwardly extending protrusions 562 arranged in a circumferential direction. The grooves formed between adjacent protrusions 562 can increase the gap between the material separating ring 56 and the outer cylinder wall. When the turntable 5 is running, the material in the gap is subjected to less extrusion pressure, thereby reducing the internal friction of the material in that area, which in turn reduces the resistance and energy consumption of the turntable 5. The material in the gap can fall onto the chassis 6 through the grooves. The protrusions 562 between two adjacent grooves can push the material to the discharge port 61, resulting in less residual material on the turntable.

[0038] Furthermore, blades 52 are connected to the lower end of the sweeping plate 53. Blades 52 are block-shaped structures, which can be square, trapezoidal, or have beveled surfaces. They extend along the inner circumference of the separating ring 56, in the same direction as the separating teeth 561, and are located between adjacent separating teeth 561, with the same thickness as the separating teeth 561. In this embodiment, after the branch ends of the support disk 54 are connected to the sweeping plate 53, four paddle structures are formed. Blades are connected to the lower end of the sweeping plate, forming a stirring or propulsion structure. In this embodiment, the ends of the paddles, blades 52, and the outer ring 51 are all located inside the outer cylinder 22, and blades 52 correspond to the discharge port 61.

[0039] In this embodiment, the chassis 6 has a higher center and a lower outer perimeter, forming a circular stepped structure. Thus, when the feeder is running, the material moves from the center to the outer perimeter, and through the circular stepped structure of the chassis, the material exhibits a "downhill" phenomenon, effectively reducing material flow resistance and equipment energy consumption.

[0040] The working principle of the turntable 5 in this embodiment is as follows: When the material enters the rotating turntable 5, the paddle formed by the connection between the support plate 54 and the sweeping plate 53 stirs the material. The paddle has an upward-curved structure, which can more effectively guide the material flow, reduce material accumulation, and reduce the resistance of the material to the paddle. The blades 52 located below the paddle can push the material during rotation to scrape the material to the discharge port 61. The material separation teeth 561 can effectively separate and guide the material, thereby improving the flow and distribution of the material. In addition, the circumferential grooves on the outer periphery of the material separation ring can reduce the resistance and energy consumption of the turntable 5, and allow the material located in the gap between the material separation ring 56 and the outer cylinder wall to fall to the base plate 6 through the grooves. The protrusions 562 between two adjacent grooves can push the material to the discharge port 61, thereby reducing the accumulation of residual material on the turntable.

[0041] The working principle of the feeder in this embodiment is as follows: the drive motor 7 drives the turntable 5 to rotate. When the turntable 5 rotates, the material in the inner cylinder 21 moves around with the turntable 5 and enters the outer cylinder 22. The turntable 5 scrapes the material to the discharge port 61. The material is discharged through the discharge port 61. The discharge amount is achieved by adjusting the height of the adjusting ring 4, that is, by lifting the adjusting ring 4 through the lifting mechanism 3 to feed the material evenly and continuously to the next process.
