AI Technical Summary
The shear rubber springs of the secondary floating frame of the existing tension screen are prone to separation and detachment or tearing under the action of lateral tension and inertial force, resulting in frequent equipment downtime for maintenance, affecting production efficiency and increasing maintenance costs.
Conical damping columns and rubber bonding holes are set on the upper and lower seat plates. The conical damping columns enhance the bonding strength between the rubber body and the seat plate and provide damping force to prevent tearing under large amplitude. A rectangular rubber seat spring structure is adopted.
This improved the operational stability and service life of the tension screen, reduced maintenance costs, and enhanced the overall performance of the equipment.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vibrating screening machinery, and mainly relates to the shear rubber spring of the secondary floating frame of the screen surface of the tension screen, which is a rectangular rubber seat spring that can improve its operating stability and service life. Background Technology
[0002] The shear rubber spring of the secondary floating frame of the existing tension screen consists of an upper seat plate, a lower seat plate, and a rubber body. The seat plate and the rubber body are only bonded together by vulcanization of the rubber and the smooth seat plate. During operation, this spring frequently experiences two mechanical failures: first, under the lateral tension of the tension screen, the upper and lower seat plates and the rubber body of the spring separate and detach; second, under the inertial force of the material and the vibrating screen body, as the amplitude increases, the rubber body, relying solely on the tensile strength of the rubber material itself without additional damping force, tears. These problems frequently require the tension screen to be shut down for maintenance, affecting production efficiency and increasing maintenance costs. Summary of the Invention
[0003] The purpose of this invention is to provide a rectangular rubber seat spring that ensures the stability of the vibration amplitude of the tension screen surface and extends the service life of the tension screen.
[0004] This utility model is achieved through the following technical solution, including an upper seat plate, a rubber body, a conical damping column, and a lower seat plate. The rubber body is located between the upper seat plate and the lower seat plate. The feature is that mounting holes are provided at both ends of the upper and lower seat plates; an upper conical damping column is provided on the right side of the upper seat plate, located within the rubber body near its right end, with its large end connected to the upper seat plate; and a lower conical damping column is provided on the left side of the lower seat plate, located within the rubber body near its left end, with its large end connected to the lower seat plate.
[0005] A buffer hole is provided on the lower seat plate at the position corresponding to the upper conical damping column, and the center of the buffer hole is located on the center line of the upper conical damping column; a buffer hole is provided on the upper seat plate at the position corresponding to the lower conical damping column, and the center of the buffer hole is located on the center line of the lower conical damping column.
[0006] Two to eight rubber bonding holes are provided on the upper and lower seat plates.
[0007] The height h of the upper and lower conical damping columns is less than or equal to half the height H of the spring; the large end diameter a of the upper and lower conical damping columns is less than the diameter c of the buffer hole; the diameter d of the rubber bonding hole is less than or equal to half the width w of the seat plate.
[0008] The beneficial effects of this invention are that, due to the conical damping columns installed on the upper and lower seat plates, the rectangular rubber seat spring subjected to shear force can ensure the bonding strength between the rubber body and the upper and lower seat plates, preventing them from falling off and separating, and also ensure that the rubber body of the seat spring is not torn under large inertial forces and large amplitudes of the tension screen. It features good performance and a simple structure, improving the overall working performance of the tension screen and reducing operating and maintenance costs. It is suitable for tension screens equipped with a secondary floating frame for the screen surface. Attached Figure Description
