Description

Technical Field

[0001] The utility model relates to the technical field of vibration devices for glass fibers, and particularly relates to a vibration device for simulating the transportation of glass fibers by an automobile. Background Art

[0002] When glass fibers are transported, they are transported by pallets. 3 - 4 layers of wound glass fibers are placed on each of the large and small pallets, and the pallets are stacked on the truck cargo box. Automobile transportation plays a crucial role in the transportation of glass fibers. However, during the transportation process by automobile, due to various factors such as bumpy roads, turning, sudden braking, starting and stopping, and going up and down slopes, it is extremely easy to damage the packaging of glass fibers, deform the yarn balls, affect the use of customers, and reduce the product quality.

[0003] Therefore, it is necessary to study the possible defects in the existing transportation process. However, there is no device in the prior art that can simulate the vibration of glass fibers during the transportation of glass fibers by an automobile, and thus it is impossible to study the potential hazards that may exist during the transportation process. Therefore, the utility model proposes a vibration device for simulating the transportation of glass fibers by an automobile. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a vibration device for simulating the transportation of glass fibers by an automobile, which solves the problem that the vibration of glass fibers during transportation cannot be simulated in the prior art.

[0005] In order to achieve the above - mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A vibration device for simulating the transportation of glass fibers by an automobile includes a main frame, a cargo platform, a driving mechanism, an eccentric shaft mechanism, and a connecting rod mechanism; the top of the main frame is connected to the cargo platform through a spring assembly; a driving mechanism and an eccentric shaft mechanism are arranged on the top of the main frame, and the driving mechanism and the eccentric shaft mechanism are in transmission connection; the eccentric shaft mechanism is movably connected to the cargo platform through the connecting rod mechanism.

[0007] In this solution, glass fibers are carried on the cargo platform; during the simulation of vibration, the driving mechanism drives the eccentric shaft mechanism to rotate. During the rotation of the eccentric shaft mechanism, the connecting rod mechanism is pulled to make a reciprocating motion, and the connecting rod mechanism drives the cargo platform to vibrate; the vibration of the cargo platform simulates the bumps generated during the transportation process by an automobile due to factors such as starting and stopping. Through this simulation vibration method, potential hazards that may exist during the transportation process can be discovered, so as to eliminate them in time, thereby ensuring the safety of glass fiber transportation.

[0008] Furthermore, the eccentric shaft mechanism includes a bearing seat, the bearing seat is installed on the main frame, and an eccentric shaft is rotatably connected in the bearing seat through a bearing; a cam is designed in the middle of the eccentric shaft, and a first bearing chamber is connected to the periphery of the cam through a bearing; a threaded hole is designed on the first bearing chamber, and the first bearing chamber is connected to the connecting rod mechanism through the threaded hole.

[0009] Further, the linkage mechanism includes a connecting rod body. One end of the connecting rod body is screwed into the threaded hole of the bearing cover, and the other end of the connecting body is connected to the second bearing chamber. A transmission rod is connected in the second bearing chamber through a bearing; both ends of the transmission rod are connected with fixing seats, and the fixing seats are installed on the side wall of the cargo platform through bolts.

[0010] In this solution, both ends of the connecting rod body are respectively threadedly connected to the first bearing chamber and the second bearing chamber, which is convenient for connecting the eccentric shaft and the transmission rod.

[0011] Further, the driving mechanism includes a motor, and the motor is installed on the top of the main frame; a small pulley is arranged on the output shaft of the motor, a large pulley is arranged at the end of the eccentric shaft, and the small pulley and the large pulley are connected by a synchronous belt.

[0012] In this solution, the motor and the eccentric shaft are connected by the small pulley and the large pulley to reduce the rotation speed of the eccentric shaft, thereby reducing the frequency of the reciprocating motion and avoiding excessive vibration from damaging the fiberglass on the cargo platform.

[0013] Further, bearing caps are arranged at both ends of the first bearing chamber; an oil seal is arranged between the bearing cap and the eccentric shaft.

[0014] Further, a number of criss-cross bearing beams are arranged inside the main frame, and reinforcing rib plates are arranged at the intersections of two mutually perpendicular bearing beams.

[0015] In this solution, the bearing beams and the reinforcing rib plates are arranged to improve the strength of the main frame; enabling it to withstand a large vibration effect.

[0016] Further, the spring assembly includes a spring fixing seat, and the spring fixing seat is installed on the bearing beam through bolts; one end of the spring is fixedly connected to the spring fixing seat, and the other end of the spring is fixedly connected to the cargo platform.

[0017] In this solution, the cargo platform is supported by springs. When the motor drives the cargo platform to vibrate, the elastic effect of the springs can provide a vibration space for the cargo platform and buffer the impact of the up and down bumps of the cargo platform.

[0018] Further, the motor is installed on the bearing beam through a motor bracket.

A bearing beam and a reinforcing rib plate are designed in the main frame, and its structure is more firm, and it can simulate that the height and weight of the cargo loaded during automobile transportation are higher and greater. By adjusting the rotation speed of the motor, various working conditions of automobile transportation can be simulated, such as starting and stopping, transportation scenarios on uneven roads, etc., which is convenient for improving the packaging and fixation during the transportation of glass fiber and reducing the quality problems caused by transportation reasons.
