Abstract
The utility model discloses an anti-vibration machine base for a food raw material classifying screen, which comprises a connecting seat, sliding blocks and a base, wherein a connecting hole is formed in the center of the connecting seat; two symmetrical chutes are formed in the lower end of the inner wall of the connecting seat; the sliding blocks are clamped in the chutes; springs are arranged between the sliding blocks and the upper and lower walls of the chutes; threaded through holes are formed in the centers of the sliding blocks; the base is connected with the connecting seat by torsional springs. The anti-vibration bed has the benefits that the vibration of the classifying screen is reduced; the tail of a rack is difficult to fracture.
Description
Technical field
The utility model relates to food processing apparatus accessory, particularly the vibration-protected frame of raw-food material classifying screen.
Background technology
Classifying screen is mainly used in the classification for screening, intermediate products or the finished product of the industry raw materials such as grain, food, chemical industry, sugaring, mining, papermaking.Classifying screen is made up of parts such as support, frame, drive unit, sieve nests, and its operation principle is that power is passed to drive unit by V belt by motor, and drive unit drives the sieve nest motion of constant slope again.Material enters sieve nest from charging aperture, under the effect of sieve nest feed end circular motion, is evenly distributed in rapidly on whole compass screen surface width, and produces automatic classification.In drive unit, dispose eccentric block, eccentric block is contrary with sieve nest installation direction, is used for the centrifugal force of balance sieve nest.Existing classifying screen can not complete equipilibrium due to inertia force, and underframe and basis to classifying screen impact, and make the vibration of classifying screen large, and tail support is easily broken.
Utility model content
The purpose of this utility model provides a kind of little, not vibration-protected frame of the raw-food material classifying screen of easy fracture of afterbody of classifying screen vibration that makes.
In order to address the above problem, the vibration-protected frame of the raw-food material classifying screen that the utility model provides, comprise Connection Block, slide block and base, described Connection Block center is provided with connecting hole, the lower end of described Connection Block inwall is provided with two symmetrical sliding trays, and described slide block is connected in sliding tray, on slide block and sliding tray, between lower wall, is provided with spring, described slide block center is provided with tapped through hole, between described base and Connection Block, connects by torsion spring.
When the classifying screen work of this support is installed; frame and slide block are threaded; spring on slide block is constantly done adaptability distortion after having absorbed the kinetic energy of sieve nest; simultaneously; self play certain damping action; reduce the effect of inertia force to frame; reduce the vibration of classifying screen; in the time of classifying screen afterbody commutation motion, because torsion spring connects between base and Connection Block, in the time that frame swings; torsion spring can give off energy; vibration while work to cushion the power of classifying screen running, to reduce extension set riddler, has played protective effect to classifying screen.
Further, in order to increase the durability of torsion spring, described torsion spring center is provided with stiffener core, by the booster action of reinforcing bar core, when the left and right that does not affect torsion spring twists to reduce vibration, makes torsion spring avoid the distortion of vertical direction.
Finally, in order to increase the buffer capacity to frame, described torsion spring is provided with side by side five, in frame, the vibration of frame is divided equally by five torsion spring actings in conjunction on five torsion springs.
Accompanying drawing explanation
Fig. 1: the structural representation that is the vibration-protected frame of the raw-food material classifying screen of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
The vibration-protected frame of raw-food material classifying screen as shown in Figure 1, comprise Connection Block 1, slide block 4 and base 7, Connection Block 1 center is provided with connecting hole 2, the lower end of Connection Block 1 inwall is provided with two symmetrical sliding trays, slide block 4 is connected in sliding tray, on slide block 4 and sliding tray, between lower wall, be provided with spring 3, slide block 4 centers are provided with tapped through hole, between base 7 and Connection Block 1, connect by torsion spring 6.
When the classifying screen work of this vibration-protected frame is installed; frame and slide block are threaded; spring on slide block is constantly done adaptability distortion after having absorbed the kinetic energy of sieve nest; simultaneously; self play certain damping action; reduce the effect of inertia force to frame; reduce the vibration of classifying screen; in the time of classifying screen afterbody commutation motion, because torsion spring connects between base and Connection Block, in the time that frame swings; torsion spring can give off energy; vibration while work to cushion the power of classifying screen running, to reduce extension set riddler, has played protective effect to classifying screen.Torsion spring 6 centers are provided with stiffener core 5, by the booster action of reinforcing bar core 5, when the left and right that does not affect torsion spring 6 twists to reduce vibration, make torsion spring 6 avoid the distortion of vertical direction.Torsion spring 6 is provided with side by side five, in frame, the vibration of frame is divided equally by five torsion spring actings in conjunction on five torsion springs.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
