Description

Technical Field

[0001] This utility model belongs to the field of material conveying machinery technology, specifically relating to a support device for an oscillating conveyor. Background Technology

[0002] In tobacco processing lines, the loosening and rehumidification process is used to loosen, heat, and humidify materials such as tobacco leaves and stems. This process typically consists of a series of interconnected devices. A typical flow is as follows: the material is first quantitatively weighed and conveyed by an electronic scale at the front end, and then fed into the drum of the loosening and rehumidification machine at the rear end for processing. In this equipment chain, an vibrating conveyor serves as the material transfer and transmission device. It is installed between the electronic scale and the drum feed hood of the loosening and rehumidification machine to receive the material output from the electronic scale and use its vibration to evenly transport the material to the rehumidification machine. The stability and reliability of this vibrating conveyor directly affect the connection between the preceding and following processes and the efficiency and quality of the entire production line.

[0003] Currently, these types of vibrating conveyors generally use an exciter motor directly mounted on the conveying trough to generate vibration force, and a flexible connection between the trough and the fixed frame is achieved through an elastic support system. A typical structure of this system includes: an upper base connected to the trough support, a lower base connected to the equipment frame, and compression springs directly fitted onto the extension columns of the upper and lower bases. In this structure, the two end faces of the spring abut against the support surfaces of the upper and lower bases, respectively, thereby achieving axial support and limitation; simultaneously, the inner surface of the spring is radially positioned and guided by the extension columns, constraining its lateral displacement during vibration. It is through this contact method, relying on its own elastic deformation, that the spring provides the necessary support stiffness and vibration restoring force for the entire vibration system.

[0004] This support system is widely used due to its simple structure and low cost, but it has also revealed inherent technical defects in long-term operation. Because the upper and lower end faces of the spring are in direct contact with the supporting surface of the metal base, under continuous high-frequency vibration, they experience severe collisions and sliding friction, leading to rapid wear at the contact points and significant impact noise. Simultaneously, due to the fit clearance between the spring and the base extension column, the spring is prone to radial yaw and axial chatter during equipment start-up, shutdown, or sudden load changes. This unstable vibration pattern is transmitted to the trough, causing amplitude fluctuations and irregular swaying, increasing the risk of interference and collisions with connected equipment. Furthermore, to meet the structural rigidity and connection strength requirements of the support system, the lower base is usually welded to the equipment frame to ensure stable transmission of vibration energy to the foundation. However, this permanent connection method, chosen for performance reasons, leads to significant maintenance difficulties: when replacing the spring or repairing the base, it must be disassembled and then re-welded after repair. This process not only significantly increases the time cost and complexity of maintenance operations, but also poses a major safety risk of sudden release of spring energy due to the need for destructive cutting during disassembly. The traditional structure, lacking necessary preload adjustment mechanisms and reliable displacement restraint devices, restricts the improvement of overall equipment performance and operational reliability.

[0005] To address the above problems, this utility model is proposed. Utility Model Content

[0006] To address the problems in existing technologies, such as severe wear and noise due to direct contact between the spring and the metal support, maintenance difficulties caused by welding and fixing of the lower base, and insufficient operational stability due to the lack of effective adjustment and limiting mechanisms, the purpose of this invention is to provide a support device for an vibrating conveyor. This device can effectively reduce component wear and operating noise, facilitate maintenance and replacement, and improve the stability and safety of equipment operation through adjustment.

[0007] The technical solution adopted in this utility model is:

[0008] A support device for an oscillating conveyor is provided, comprising:

[0009] Fixed base 1, used for fixed installation on the equipment frame;

[0010] The lower support 2 is fixed to the upper part of the fixed base 1 by a detachable connection;

[0011] The elastic component 4 is supported on the lower support base 2;

[0012] The upper support 3 is supported on the elastic component 4 and can elastically displace relative to the lower support 2;

[0013] The lower end of the connecting screw 5 passes through the upper support 3 and is connected to it via the first locking assembly 8;

[0014] The bottom of the trough connector 6 is connected to the upper end of the connecting screw 5, and is used to support the trough of the vibrating conveyor.

[0015] Multiple limiting screws 7 pass through the corresponding mounting holes on the upper support 3, lower support 2 and fixed base 1 in sequence, detachably connecting the three into one unit and limiting the maximum displacement stroke of the upper support 3.

[0016] Preferably, the upper support 3 and the lower support 2 are respectively provided with coaxially opposite positioning bosses 9, and the positioning bosses 9 are fitted with noise reduction bushings 10 through interference fit.

[0017] The two ends of the elastic component 4 are respectively sleeved on the outer periphery of the noise reduction bushing 10 of the upper and lower positioning bosses 9 and abut against the facing surfaces of the upper support 3 and the lower support 2. The noise reduction bushing 10 radially separates the elastic component 4 from the positioning bosses 9. An axial gap is formed between the end faces of the two positioning bosses 9, and the natural length of the elastic component 4 is greater than the axial gap.

[0018] Preferably, the noise reduction bushing 10 is a sleeve structure with one end closed and the other end open, and its closed end is located at the end of the positioning boss 9.

[0019] Preferably, the connecting screw 5 has an external thread on its shaft, and the first locking assembly 8 locks and fixes the connecting screw 5 to the upper support 3 by engaging with the external thread.

[0020] Preferably, the bottom of the groove connector 6 is provided with a threaded hole, the upper end of the connecting screw 5 is screwed into the threaded hole, and locked and fixed by the second locking assembly 11 provided on the connecting screw 5.

[0021] Preferably, there are four limiting screws 7, which are respectively set at the four corners of the support device; the limiting screws 7 are provided with external threads on their shafts and pass through the corresponding mounting holes on the upper support seat (3), the lower support seat 2 and the fixed base 1 in sequence;

[0022] The two ends of the limiting screw 7 are screwed with a third locking component 12. By adjusting the axial position of the third locking component 12 on the limiting screw 7, the final distance between the upper support 3 and the lower support 2 can be set and locked, thereby determining the pre-compression amount of the elastic component 4.

[0023] Preferably, the first locking component 8, the second locking component 11, and the third locking component 12 are all nuts.

[0024] Preferably, the elastic component 4 is a helical compression spring.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model achieves non-direct contact between the elastic component and the metal support by setting noise-reducing bushings on the positioning bosses of the upper and lower support seats. This structure effectively avoids rigid collisions and friction between the spring and the metal parts under high-frequency vibration conditions, thereby significantly reducing equipment operating noise, greatly slowing down the wear rate of the contact parts, and extending the service life of the core components.

[0027] 2. This utility model adopts a split, detachable connection structure, changing the connection method between the lower support and the fixed base from traditional welding to bolt connection. This improvement eliminates the need for destructive cutting and re-welding when replacing elastic components or performing other maintenance work, greatly simplifying the disassembly and installation process, shortening equipment downtime, improving the safety and efficiency of maintenance work, and effectively solving the fundamental problem of difficult maintenance of traditional structures.

[0028] 3. This utility model constructs a precise adjustment and limiting mechanism by setting a limiting screw with external threads and a matching locking assembly. The final distance between the upper and lower support seats can be easily set and locked by turning the locking assembly, thereby achieving precise control of the pre-compression of the elastic component. This not only optimizes the rigidity of the support system and ensures the operational stability of the equipment under various working conditions, but also effectively limits the maximum amplitude of the vibration tank, preventing collisions and interference with upstream and downstream connected equipment, and improving the reliability of the entire production line.

[0033] The present invention will be further described in detail below with reference to embodiments, but this is not intended to limit the present invention. Any modifications or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the field or in accordance with the product manual.

[0034] Example 1

[0035] Please see Figure 1 and Figure 2 This utility model provides a support device for an oscillating conveyor, which mainly includes a fixed base 1, a lower support 2, an upper support 3, an elastic component 4, a connecting screw 5, a trough connector 6, a limiting screw 7, and corresponding locking components.

[0036] The fixed base 1 is fixedly installed on the equipment frame by welding, and its bottom dimensions are adapted to the cross-sectional dimensions of the support legs of the equipment frame, providing a stable foundation for the entire support device. The lower support 2 is detachably connected to the fixed base 1, specifically by the limiting screw 7 described later.

[0037] The elastic component 4 is a helical compression spring, which is supported on the lower support 2. The upper support 3 is supported on the elastic component 4 and can undergo elastic displacement relative to the lower support 2 under the elastic action of the elastic component 4.

[0038] The upper support 3 and the lower support 2 are respectively provided with coaxially opposite positioning bosses 9 on their facing surfaces. A noise-reducing bushing 10 made of nylon material is interference-fitted onto the positioning bosses 9. The noise-reducing bushing 10 adopts a sleeve structure with one end closed and the other open, with the closed end located at the end of the positioning boss 9. This structure effectively prevents impurities from entering the mating surface. The two ends of the elastic component 4 are respectively fitted onto the outer periphery of the noise-reducing bushing 10 on the upper and lower positioning bosses 9. Its inner ring is adapted to the outer peripheral surface of the noise-reducing bushing 10, forming a radial fit, and abuts against the facing surfaces of the upper support 3 and the lower support 2. This structure allows the noise-reducing bushing 10 to radially separate the elastic component 4 from the positioning bosses 9, avoiding direct metal-to-metal contact. Simultaneously, an axial gap is formed between the end faces of the two positioning bosses 9, and the natural length of the elastic component 4 is greater than this axial gap, ensuring that the elastic component 4 is in a pre-compressed state after installation.

[0039] The connecting screw 5 has an external thread on its shaft, and its lower end passes through the upper support 3 and is connected and fixed to it through the first locking assembly 8. The bottom of the groove connector 6 has a threaded hole, and the upper end of the connecting screw 5 is screwed into the threaded hole and locked and fixed by the second locking assembly 11 provided on the connecting screw 5. Both the first locking assembly 8 and the second locking assembly 11 are nuts.

[0040] Four limiting screws 7 are provided, respectively located at the four corners of the support device, forming a stable support frame. Each limiting screw 7 has an external thread and passes sequentially through corresponding mounting holes on the upper support 3, lower support 2, and fixed base 1. A third locking assembly 12, also a nut, is screwed onto both ends of each limiting screw 7. By adjusting the axial position of the third locking assembly 12 on the limiting screw 7, the final distance between the upper support 3 and lower support 2 can be precisely set and locked, thereby determining the pre-compression of the elastic component 4 and ensuring the vibration system has appropriate support stiffness.

[0041] The working principle and process of this utility model are as follows:

[0042] During operation, the vibration force generated by the vibrating motor of the vibrating conveyor is transmitted through the trough to the trough connector 6, and then through the connecting screw 5 to the upper support seat 3. The upper support seat 3 generates continuous elastic vibration under the support of the elastic component 4. The noise reduction bushing 10 effectively isolates the direct contact between the elastic component 4 and the metal support seat, significantly reducing the noise and component wear generated during vibration.

[0043] By adjusting the third locking assembly 12 at the upper end of the limiting screw 7, the distance between the upper support 3 and the lower support 2 can be precisely controlled, thereby adjusting the pre-compression of the elastic component 4 and ensuring that the vibration system has stable vibration characteristics under various working conditions. At the same time, the cooperation between the limiting screw 7 and the third locking assembly 12 effectively limits the maximum displacement stroke of the upper support 3, preventing the vibration tank from colliding and interfering with the equipment in front and behind.

[0044] When it is necessary to replace the elastic component 4 or perform maintenance, the pre-compression force of the elastic component 4 can be slowly released by gradually adjusting the third locking components 12 at both ends of the limit screw 7, thus achieving safe disassembly. The entire support device adopts a fully detachable connection structure, avoiding the cutting operations required by traditional welding methods, greatly simplifying the maintenance process, and improving operational safety and maintenance efficiency.

[0045] This utility model, through its innovative structural design, organically combines functions such as noise reduction and wear reduction, convenient maintenance, stable operation, and safety protection, effectively solving many technical problems existing in traditional vibrating conveyor support devices. It has high practical value and promotion significance.
