Description

Technical Field

[0001] This utility model relates to the field of waste circuit board recycling and processing technology, and more specifically to a vibratory feeder for waste circuit board recycling and processing. Background Technology

[0002] In the recycling and processing of waste circuit boards, vibrating feeders are key equipment that use vibration principles to automatically transport, sort, and orient materials. They are mainly used to stably and evenly transport fragments (such as mixtures of metal particles and resin fibers) or uncrushed small pieces of waste circuit boards to subsequent processing stages such as sorting, screening, and purification, according to specific requirements. Among them, electromagnetic vibrating feeders are widely used.

[0003] Traditional electromagnetic vibrating feeders generate vibrations during operation, typically connected to the base via springs. However, relying solely on springs for vibration damping has significant drawbacks: springs are prone to elastic fatigue over long-term use, leading to a decrease in damping effectiveness and an increase in the overall vibration amplitude of the equipment. This can cause unstable material conveying speeds (fluctuating speeds) and reduced sorting and orientation accuracy (e.g., the inability to separate mixed metal particles and resin fibers along a preset trajectory), affecting the efficiency and quality of subsequent processes. Furthermore, the rigid connection between the equipment and the springs, and between the springs and the base plate, results in high-frequency collisions and friction between components during vibration. The elastic deformation of the springs themselves also generates noise due to internal friction. Combined with the impact sound of materials hitting the trough, this creates a prolonged high-noise environment, which can damage operators' hearing, affect their concentration, increase the risk of operational errors, and cause noise pollution to the surrounding environment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vibratory feeder for recycling and processing waste circuit boards, so as to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a vibratory feeder for recycling and processing waste circuit boards, including an electromagnetic vibratory feeder body and a base plate installed at the bottom of the electromagnetic vibratory feeder body. A buffer seat is sleeved on the outside of the base plate, and a base is sleeved on the outside of the buffer seat. A connecting rod is fixedly connected to the center of the bottom of the buffer seat. An elastic sleeve is sleeved on the outer surface of the connecting rod. The outer surface of the elastic sleeve is movably connected to the inside of the base. A positioning and pressure boosting component is installed at the connection between the base plate and the buffer seat.

[0006] Furthermore, the positioning and pressurizing assembly includes sealing grooves at both ends inside the buffer seat. A sealing block is slidably connected inside the sealing groove. A connecting column is fixedly connected to the center of the side of the sealing block. A return spring is movably sleeved on the outer surface of the connecting column. A stop column is fixedly connected to the top of the connecting column. Slots are provided on both sides of the bottom of the base plate. A connecting pipe communicating with the inside of the sealing groove is fixedly connected inside the buffer seat. Airbags are fixedly installed at equal intervals inside the buffer seat. The inside of the connecting pipe is connected to the inside of the airbags. A valve core is fixedly connected inside the buffer seat and communicates with the inside of the connecting pipe. A pressure gauge is fixedly installed on the top of the buffer seat. The input end of the pressure gauge is connected to the inside of the connecting pipe.

[0007] Furthermore, the input end of the valve core valve extends to the top of the buffer seat, and the interior of the airbag is connected to the interior of the sealing groove through a connecting pipe.

[0008] Furthermore, under normal conditions, the elasticity of the return spring causes the sealing block to slide away from the slot. The return spring is square, and a sealing ring is fixedly installed on the outer surface of the sealing block.

[0009] Furthermore, the airbag is frame-shaped, the surface of the airbag near the base is arc-shaped, the elastic sleeve and the connecting rod are both convex, the interior of the elastic sleeve has a groove that matches the connecting rod, and the material of the elastic sleeve is silicone.

[0010] Furthermore, the buffer seat is movably connected to the inside of the base, and square grooves are provided on the upper surfaces of both the buffer seat and the base. The abutment and the slot are "7" shaped, the inner bottom wall of the slot is inclined, and the end face of the abutment away from the connecting column is arc-shaped.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model significantly optimizes shock absorption performance through the synergistic effect of multiple buffer structures. On the one hand, the connecting rod at the bottom of the buffer seat and the elastic sleeve of silicone material form a primary buffer, using the elastic deformation of silicone to absorb part of the vibration energy. On the other hand, after the airbag in the positioning and pressurizing component is inflated, it fits tightly against the base through flexible contact, forming a secondary buffer by utilizing the compressibility of gas. Combined with the elastic reset function of the reset spring, it effectively counteracts the high-frequency vibration generated during equipment operation. Compared with traditional single spring shock absorption, this combined buffer design can avoid the attenuation of shock absorption effect caused by elastic fatigue, making the material conveying speed more stable, reducing the trajectory deviation of metal particles and resin fibers during mixed conveying due to excessive vibration amplitude, and improving the efficiency and accuracy of subsequent sorting and screening processes.

[0013] 2. This utility model device uses flexible connections instead of traditional rigid connections, which fundamentally reduces the noise from component collisions and friction during vibration transmission. In the positioning and pressurizing component, the sealing sliding fit between the sealing block and the sealing groove, the arc-shaped contact between the airbag and the base, and the silicone material properties of the elastic sleeve all reduce the rigid impact during vibration transmission. At the same time, the flow of gas inside the airbag can absorb some vibration sound waves, further weakening noise propagation. In addition, the stable connection achieved by the inclined fit between the "7"-shaped abutment and the slot avoids additional noise caused by loose components. These designs work together to significantly reduce the noise level of the equipment during operation, protecting the hearing health of operators, reducing the risk of operational errors, and reducing noise pollution to the surrounding environment.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] A vibratory feeder for recycling and processing waste circuit boards includes an electromagnetic vibratory feeder body 1 and a base plate 2 installed at the bottom of the electromagnetic vibratory feeder body 1. A buffer seat 3 is sleeved on the outside of the base plate 2, and a base 6 is sleeved on the outside of the buffer seat 3. A connecting rod 4 is fixedly connected to the center of the bottom of the buffer seat 3. An elastic sleeve 5 is sleeved on the outer surface of the connecting rod 4. The outer surface of the elastic sleeve 5 is movably connected to the inside of the base 6. A positioning and pressure boosting component 7 is installed at the connection between the base plate 2 and the buffer seat 3.

[0023] In this embodiment, the base plate 2 and the buffer seat 3 are fitted together, and the buffer seat 3 and the base 6 are connected to form a multi-layer nested structure, which provides a spatial basis for vibration buffering.

[0024] The convex fit between the connecting rod 4 and the elastic sleeve 5 ensures the longitudinal positioning of the buffer seat 3 and the base 6, and also achieves initial shock absorption through the deformation of the silicone elastic sleeve 5, reducing the direct transmission of vibration to the base 6.

[0025] The addition of the positioning and pressurizing component 7 enables a stable connection between the base plate 2 and the buffer seat 3 during equipment installation through air pressure adjustment. At the same time, the flexible support of the airbag 78 enhances the buffering effect, solving the vibration transmission problem of traditional hard connections.

[0026] Specifically, the positioning and pressurizing assembly 7 includes sealing grooves 71 at both ends inside the buffer seat 3. A sealing block 72 is slidably connected inside the sealing groove 71. A connecting post 74 is fixedly connected to the center of the side of the sealing block 72. A return spring 73 is movably sleeved on the outer surface of the connecting post 74. A stop post 75 is fixedly connected to the top of the connecting post 74. Slots 76 are provided on both sides of the bottom of the base plate 2. A connecting pipe 77 connected to the inside of the sealing groove 71 is fixedly connected inside the buffer seat 3. Airbags 78 are fixedly installed at equal intervals inside the buffer seat 3. The inside of the connecting pipe 77 is connected to the inside of the airbags 78. A valve core valve 8 connected to the inside of the connecting pipe 77 is fixedly connected inside the buffer seat 3. A pressure gauge 9 is fixedly installed on the top of the buffer seat 3. The input end of the pressure gauge 9 is connected to the inside of the connecting pipe 77.

[0027] In this embodiment, the sealing groove 71 and the sealing block 72 are in a sealing sliding fit. The sealing block 72 can be moved by the change of air pressure to realize the automatic locking of the abutment 75 and the slot 76, which simplifies the installation process.

[0028] The connecting pipe 77 connects the sealing groove 71 to the airbag 78, so that the air pressure regulation acts synchronously on the locking mechanism and the buffer mechanism, ensuring that the equipment completes the buffer parameter setting while being fixed.

[0029] The valve core valve 8 facilitates connection to external pressurization equipment, and the pressure gauge 9 can monitor the internal pressure in real time, allowing operators to adjust the pressure of the airbag 78 according to the material characteristics, such as the mixing ratio of metal particles and resin fibers, to optimize the buffering effect.

[0030] Specifically, the input end of the valve core valve 8 extends to the top of the buffer seat 3, and the interior of the airbag 78 is connected to the interior of the sealing groove 71 through the connecting pipe 77.

[0031] In this embodiment, the valve core valve 8 extends to the top of the buffer seat 3, which facilitates the connection of external inflation equipment and allows for pressure adjustment without disassembling parts, making operation convenient.

[0032] The airbag 78 is connected to the sealing groove 71 through the connecting pipe 77, so that the sliding of the sealing block 72 and the expansion of the airbag 78 are synchronized, ensuring that the airbag 78 forms an effective buffer during the fixing of the base plate 2, avoiding secondary adjustments after installation.

[0033] Specifically, under normal conditions, the elasticity of the return spring 73 causes the sealing block 72 to slide away from the slot 76. The return spring 73 is square, and a sealing ring is fixedly installed on the outer surface of the sealing block 72.

[0034] In this embodiment, under normal conditions, the reset spring 73 pushes the sealing block 72 away from the slot 76, which facilitates the insertion and removal of the base plate 2 and simplifies the equipment loading and unloading process.

[0035] Compared to a circular spring, the square return spring 73 is more stable during compression, reduces lateral displacement, and ensures that the sealing block 72 slides axially along the sealing groove 71.

[0036] The sealing ring on the outer surface of the sealing block 72 enhances the airtightness of the sealing groove 71, preventing locking failure and reduced cushioning effect of the airbag 78 caused by air pressure leakage.

[0037] Specifically, the airbag 78 is frame-shaped, the surface of the airbag 78 near the base 6 is arc-shaped, the elastic sleeve 5 and the connecting rod 4 are both "convex" shaped, the elastic sleeve 5 has a groove inside that matches the connecting rod 4, and the elastic sleeve 5 is made of silicone.

[0038] In this embodiment, the frame-shaped airbag 78 increases the contact area with the base 6, and the arc-shaped surface design allows the airbag 78 to fit evenly against the inner wall of the base 6 when it expands, improving buffering stability and avoiding wear of the base 6 caused by excessive local stress.

[0039] The convex elastic sleeve 5 and the groove of the connecting rod 4 cooperate to form an axial limiting structure to prevent the buffer seat 3 from separating from the base 6. At the same time, the silicone elastic sleeve 5 has strong aging resistance and is not prone to elastic fatigue after long-term use, thus extending the service life of the equipment.

[0040] Specifically, the buffer seat 3 is movably connected inside the base 6. Both the buffer seat 3 and the upper surface of the base 6 are provided with square grooves. The abutment 75 and the slot 76 are "7" shaped. The inner bottom wall of the slot 76 is inclined. The end face of the abutment 75 away from the connecting post 74 is arc-shaped.

[0041] In this embodiment, the movable connection between the buffer seat 3 and the base 6 provides displacement space for vibration buffering, and the square groove design on the upper surface facilitates the arrangement of cables or pipes, avoiding pipe entanglement during equipment operation.

[0042] The inclined surfaces of the “7”-shaped abutment 75 and the slot 76 engage to convert the air pressure thrust into the locking force of the base plate 2, ensuring a tight connection between the base plate 2 and the buffer seat 3 and reducing relative displacement during vibration.

[0043] The arc-shaped end face of the abutment 75 contacts the bevel of the slot 76, reducing the frictional resistance when the two are engaged, reducing wear, and avoiding additional noise caused by the collision of sharp edges and corners.

[0044] The working principle and usage process of this utility model are as follows: During use, the main body 1 of the electromagnetic vibrating feeder is moved by the hoisting equipment, and the base plate 2 is placed inside the buffer seat 3. Then, the valve core valve 8 is connected by the pressurizing equipment to pressurize the inside of the connecting pipe 77. The high pressure enters the sealing groove 71 through the connecting pipe 77. Due to the high pressure inside the sealing groove 71, the sealing block 72 drives the connecting column 74 and the abutment column 75 to slide away from the connecting rod 4. At this time, the arc-shaped end face of the abutment column 75 is inside the slot 76. Through the abutment column 75 and the inclined surface of the slot 76, the bottom of the base plate 2 is tightly attached to the surface of the base 6. At this time, the base plate 2 is fixedly connected inside the buffer seat 3.

[0045] While pressurizing the inside of the connecting pipe 77, the inside of the airbag 78 is also pressurized and gradually expands. After the airbag 78 expands, its surface presses tightly against the surface of the base 6. According to the pressure gauge 9, the internal pressure of the airbag 78 is increased to a suitable level. When the electromagnetic vibrating feeder body 1 vibrates during operation, it drives the base plate 2 to vibrate. When the base plate 2 vibrates, it can be directly damped by the elasticity of the airbag 78. At the same time, when the base plate 2 drives the connecting rod 4 to vibrate, it can also be buffered by the elasticity of the elastic sleeve 5. All connections between the buffer seat 3 and the base 6 are flexible connections, which reduces the drawback of noise generated during operation.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
