Description

Technical Field

[0001] This utility model mainly relates to the field of waste treatment equipment technology, specifically to a vibration anti-clogging material feeding structure for a lightweight waste color sorting device. Background Technology

[0002] In the field of modern waste resource utilization, efficient sorting of lightweight waste (such as plastic film, foam products, paper scraps, etc.) is a key link to achieve material recycling. A typical sorting production line includes core processes such as pretreatment, color sorting and identification, material unloading and sorting, and subsequent conveying. Among them, the material unloading structure, as the connecting component between the color sorting device and the sorting system, directly affects the overall processing efficiency.

[0003] Because lightweight waste has characteristics such as low density, irregular shape, and high surface friction coefficient, it is easy to form arch bridges that block or adhere to the bucket wall in the conical bucket, leading to interruption of the sorting process and even causing equipment overload failure.

[0004] During the actual implementation process, the inventors discovered the following defects:

[0005] In existing technologies, conventional material feeding structures mainly rely on a single vibrating motor to drive the bucket to vibrate in order to prevent clogging. However, a single vibration source is difficult to form a uniform material fluidization effect, and material is prone to stagnation in the corner areas of the bucket, which is especially ineffective for thin film-like lint-like waste.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model:

[0008] The vibration-anti-clogging material feeding structure of the lightweight waste color sorting device provided by this utility model is used to solve the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: a vibration anti-clogging material feeding structure for a lightweight waste color sorting device, comprising a conical hopper, wherein a shock-absorbing base and a material feeding conveying channel are sequentially arranged at the lower end of the conical hopper, a vibration motor is arranged on the outside of the conical hopper, a shock-absorbing connecting component is fixedly connected between the conical hopper and the shock-absorbing base, a pneumatic anti-clogging component is provided inside the conical hopper, the lower end of the conical hopper is connected to the shock-absorbing base, the pneumatic anti-clogging component includes a ventilation shaft, an air blowing ring is provided on the ventilation shaft, and an air pump is connected to one end of the ventilation shaft.

[0011] Furthermore, the shock-absorbing base includes an annular base plate and a flange, and multiple airbag assemblies are provided between the lower end of the annular base plate and the material conveying channel.

[0012] Furthermore, a buffer sealing ring is provided at the connection between the annular bottom plate and the conical bucket, and multiple positioning holes are provided at the edge of the annular bottom plate.

[0013] Furthermore, the upper end of the conical bucket has an edge, and multiple positioning holes two corresponding to the positioning hole one are provided on the edge.

[0014] Furthermore, the shock-absorbing connection assembly includes multiple telescopic rods arranged around the edge of the conical bucket and the shock-absorbing base. Each telescopic rod is fitted with a telescopic spring and has a U-shaped buckle connected to both its upper and lower ends. The U-shaped buckles are respectively inserted into the edge of the shock-absorbing base.

[0015] Furthermore, the upper and lower ends of the telescopic rod pass through the first positioning hole and the second positioning hole, respectively, and are fixedly connected to the U-shaped buckle by locking nuts.

[0016] Furthermore, the air blowing ring has multiple circumferentially arranged air holes, and the multiple air holes are connected to the air shaft.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] The combination of a vibrating motor and an anti-clogging component breaks down the material arch structure and, in conjunction with airflow, generates thrust on the material, breaking up the lightweight waste that has become clogged.

[0020] By absorbing horizontal vibration energy through the shock-absorbing connection components and buffering vertical impact force through the airbag components, the energy transmitted by vibration is effectively reduced, and the noise generated during equipment operation is reduced.

[0021] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0032] See attached document Figure 1-4 The vibration anti-clogging material feeding structure of the lightweight waste color sorting device includes a conical hopper 1. The lower end of the conical hopper 1 is sequentially provided with a shock-absorbing base 2 and a material feeding conveying channel 4. A vibration motor 6 is provided on the outside of the conical hopper 1. The shock-absorbing connecting component 3 is fixedly connected between the conical hopper 1 and the shock-absorbing base 2. A pneumatic anti-clogging component 5 is provided inside the conical hopper 1. The lower end of the conical hopper 1 is connected to the shock-absorbing base 2. The pneumatic anti-clogging component 5 includes a ventilation shaft 501, an air blowing ring 502 is provided on the ventilation shaft 501, and an air pump 503 is connected to one end of the ventilation shaft 501.

[0033] The shock-absorbing base 2 is flexibly connected to the lower end of the conical hopper 1 via the shock-absorbing connecting assembly 3. Their central axes coincide, ensuring the material falls vertically. The upper surface of the material discharge conveying channel 4 is connected to the flange 202 of the shock-absorbing base 2, and its side connects to subsequent sorting or collecting equipment. The shock-absorbing base 2 consists of an annular base plate 201 and a flange 202, which are welded together to form a T-shaped support structure. Eight evenly distributed positioning holes 2011 are provided on the upper surface edge of the annular base plate 201 for connection and positioning with the conical hopper 1. A connection is provided between the lower end of the annular base plate 201 and the material discharge conveying channel 4. Three sets of evenly distributed airbag assemblies 203 are placed. Each set contains two layers of rubber airbags with a steel buffer plate sandwiched in between. They are fixed to the base plate and the material conveying channel 4 by bolts. The airbags are filled with 0.2MPa compressed air, which can absorb the vertical impact force transmitted by the vibration of the conical bucket 1. At the same time, it allows the anti-vibration base 2 to deflect by ±5° to adapt to the impact of materials. The buffer sealing ring 7 is made of neoprene rubber with a lip-shaped cross section. Its inner ring is tightly fitted to the outer circle of the lower end of the conical bucket 1, and its outer ring is embedded in the annular base plate 201 to form a dynamic sealing structure to prevent dust from overflowing.

[0034] The conical hopper 1 adopts an inverted frustum-shaped design that is wider at the top and narrower at the bottom. The upper end is open to receive light waste after color sorting, and the lower end is narrowed to form the discharge end. The upper end of the conical hopper 1 has an edge 101, on which multiple positioning holes 1011 corresponding to positioning hole 1 2011 are opened. Positioning hole 1011 is coaxial with positioning hole 2011 of the annular bottom plate 201. During installation, 8 sets of shock-absorbing connecting components 3 pass through the positioning holes to achieve flexible connection. The vibration motor 6 is fixed to the middle of the outer side of the conical hopper 1. The eccentric block of the motor output shaft can generate horizontal excitation force, which drives the conical hopper 1 to generate high-frequency micro-amplitude vibration, avoiding material retention on the hopper wall.

[0035] The shock-absorbing connection assembly 3 includes multiple telescopic rods 301 evenly distributed around the circumference of the conical bucket 1. Each telescopic rod 301 has threaded sections at its upper and lower ends, and a telescopic spring 302 is sleeved in the middle of the rod body. Its two ends abut against the U-shaped buckles 303 at the upper and lower ends, respectively. The grooves inside the opening of the U-shaped buckle 303 respectively engage with the edge 101 of the conical bucket 1 and the edge of the annular bottom plate 201. After the threaded sections at the upper and lower ends of the telescopic rod 301 pass through the second positioning hole 1011 and the first positioning hole 2011, respectively, they are fixed to the U-shaped buckle 303 by the locking nut 304. The telescopic spring 302 is in a pre-compressed state, which can provide continuous elastic support force.

[0036] The pneumatic anti-clogging component 5 is arranged in the lower middle part of the conical bucket 1. The core component, the ventilation shaft 501, is a hollow tubular structure that is horizontally mounted on the mounting seats on both sides of the bucket wall via bearings. It can rotate slightly around the axis to adapt to vibration. The air blowing ring 502 is a circular tube that is fitted into the middle of the ventilation shaft 501 and welded and fixed. Multiple air holes 5021 are evenly distributed on its annular surface. The air pump 503 is connected to one end of the ventilation shaft 501 through a pressure-resistant hose. Compressed air enters the air blowing ring 502 through the inner cavity of the ventilation shaft 501 and is ejected from the air holes 5021 to form an annular airflow. This blows away the blocked material, which is then rearranged and falls down with inertia, thus preventing blockage of the material discharge port of the conical bucket 1.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
