Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

Referring to fig. 1-4, the present application provides a vibratory screening apparatus for screening spring and abrasive material, comprising a vibratory assembly 1 and a screening portion 2 connected together; the vibrating component 1 can provide vibrating power for vibrating screening of the screening part 2; the screening part 2 comprises a screening groove 21 and a screening plate 22, the screening plate 22 is arranged in the screening groove 21 and is provided with a plurality of screening holes 221, and the screening holes 221 can separate different components of a material to be screened according to the size of the screening holes 221 under the action of vibration; the screening tank 21 has at least two discharge ports 211, and the at least two discharge ports 211 can respectively discharge different components screened and separated by the screening plate 22.

Wherein the vibration assembly 1 may use a vibration motor, which may be in contact with the sieving slot 21 to continuously provide vibration to the sieving slot 21 and the sieving plate 22 connected to the sieving slot 21. The sifting groove 21 may include a groove bottom 213 and sidewalls 212. The different components of the material to be screened refer to the components of the material to be screened which have different sizes, and may include different components such as springs and abrasives, or some mixed impurities. During the vibration screening, the material to be screened is laid on the screening plate 22.

The working process and the working principle of the embodiment are as follows: the vibrating screen device uses vibration to separate the different components of the material to be screened through the screen openings 221 in the screen deck 22. Specifically, the vibration component 1 is turned on, the vibration component 1 continuously provides vibration for the screening groove 21 and the screening plate 22 connected to the screening groove 21, the material to be screened laid on the screening plate 22 continuously shakes or beats under the vibration effect of the screening plate 22, so that components (such as abrasive materials) with the size smaller than the screening holes 221 in the material to be screened continuously pass through the screening holes 221 and fall below the screening plate 22, and components (such as springs) with the size larger than the screening holes 221 in the material to be screened cannot pass through the screening holes 221, so that the components stay on the screening plate 22, screening and separation of different components in the material to be screened are achieved, and finally the screened components are respectively led out from different discharge holes 211.

The spring and the abrasive are screened by vibration of the vibration screening equipment, so that a worker is not required to manually separate the spring from the abrasive, the screening efficiency is improved, and the production cost is reduced. Secondly, if the abrasive material card appears in the internal condition of spring, the abrasive material card in the spring just can be shaken very easily to lasting vibration, need not artifical the taking out. Finally, only the screening plate 22 with the screening holes 221 of the proper size needs to be selected, the spring and the abrasive can be effectively separated under the action of vibration, the situation that the spring is omitted in the abrasive is not easy to occur, and the product quality and the yield are improved.

As shown in fig. 3, as an embodiment, the screening plates 22 respectively include a first screening plate 222 and a second screening plate 223, and the first screening plate 222 and the second screening plate 223 are sequentially disposed in the screening slot 21 from top to bottom; the screening holes 221 in the first screening plate 222 are larger than the screening holes 221 in the second screening plate 223. After the spring is ground and polished by using an abrasive, a part of abrasive particles may become smaller due to abrasion. In the embodiment, the second screening plate 223 is arranged below the first screening plate 222, after the springs and the abrasive are screened by the first screening plate 222, the larger springs are left on the first screening plate 222, and the smaller abrasive falls onto the second screening plate 223 below. Since the screening holes 221 of the second screening plate 223 are smaller than the first screening plate 222, the abrasive falling on the second screening plate 223 can be further screened, the abrasive with larger particles stays on the second screening plate 223, and the abrasive with smaller particles continuously falls through the screening holes 221 of the second screening plate 223 and can fall onto the groove bottom 213 of the screening groove 21, so as to further screen the abrasive. Since the spring polishing has requirements on the size range of abrasive particles, the second screening plate 223 with the screening holes 221 with proper sizes is selected to screen out the abrasive materials meeting the size requirements of the abrasive particles so as to reuse the abrasive materials, and the production cost is saved. And the spring, the grinding materials and the grinding materials with different particle sizes can be screened simultaneously, so that the production efficiency is improved. As a further improvement, three or more sieving plates 22 may be disposed in the sieving tank 21 from top to bottom at a time, and the size of the sieving holes 221 may be reduced from top to bottom accordingly, so as to sieve the material to be sieved more finely.

As shown in fig. 2, as an embodiment, the discharge ports 211 respectively include a first discharge port 2111, a second discharge port 2112 and a third discharge port 2113; the first discharge port 2111 is communicated with the upper side space of the first screening plate 222, and can outwards guide out the materials (i.e. the components of the materials to be screened after being screened) on the first screening plate 222; the space clamped by the first screening plate 222 and the second screening plate 223 is communicated with the second discharge port 2112, and materials on the second screening plate 223 can be led out; the space between the bottom 213 of the screening groove 21 and the second screening plate 223 is communicated with the third discharge port 2113, so that the material on the bottom 213 of the screening groove 21 can be discharged outwards. Specifically, the first discharge port 2111 leads the polished spring outwards, the second discharge port 2112 leads the abrasive with larger particles outwards, and the third discharge port 2113 leads the abraded abrasive with smaller particles or some impurities with smaller particle size outwards. Further, the first discharge port 2111, the second discharge port 2112 and the third discharge port 2113 are respectively connected with a guide slot 5 to guide the material coming out of the discharge port 211 into the corresponding container.

As shown in fig. 2-3, as an embodiment, the local vibratory screening apparatus further includes a platen assembly 3, the platen assembly 3 includes a platen 31, and the platen 31 is disposed above the first screening plate 222. Preferably, the pressing plate 31 may be disposed in parallel with the first sieving plate 222. The pressing plate 31 is arranged above the first screening plate 222, so that the material to be screened can be prevented from jumping out of the screening groove 21 due to vibration during vibration screening. Specifically, the pressing plate 31 may be made of a transparent material, such as glass, acrylic, etc., so that the worker can observe the screening condition of the screening plate 22 more clearly.

Further, a portion of the springs may be erected relative to the sieve plate 22 under the action of vibration, and considering that some springs are slender, if the springs are erected and then pass through the sieve holes 221 during the vibration sieving, the processed springs are mixed into the sieved abrasive. To address this problem, the pressure plate 31 is located a distance from the first sifting plate 222 that is greater than the diameter of the spring and less than the length of the spring. When the spring is set in this way, it tends to stand up due to vibration, and is blocked by the upper pressure plate 31. By this arrangement, the spring is prevented from standing up and a relatively slender spring is prevented from passing through the sifting aperture 221, so that the processed spring is mixed into the sifted abrasive material.

As shown in fig. 2-3, further, the pressing plate assembly 3 further includes a pressing plate fixing member 32 and a height adjusting member 33 provided on the sidewall 212 of the sieving tank 21; the height adjusting member 33 holds up the pressing plate 31, and the pressing plate fixing member 32 presses the pressing plate 31 downward; the distance between the pressing plate 31 and the first sifting plate 222 can be adjusted by the height adjuster 33. The pressing plate fixing member 32 and the height adjusting member 33 respectively apply forces to the pressing plate 31 from both upper and lower directions, thereby firmly fixing the pressing plate 31 in the sieving tank 21. The distance between the pressure plate 31 and the first screening plate 222 is adjusted by the height adjusting member 33, so that the screening part 2 can be better adapted to more springs with different specifications and different sizes. Specifically, the height adjusting part 33 can be adjusted according to the difference between the diameter and the length of the spring, so that the distance between the pressing plate 31 and the first screening plate 222 is greater than the diameter of the spring and smaller than the length of the spring, the purpose of preventing the processed spring from being mixed into the screened abrasive material is achieved, the application range of the dynamic screening equipment for different springs is expanded, and the utilization rate is improved. Specifically, the platen fixing member 32 and the height adjusting member 33 each have a plurality to firmly fix the platen 31.

As one specific example, the pressing plate fixing member 32 may be a pressing plate 31 fixing buckle, and the height adjusting member 33 may be a height adjusting screw screwed to the sidewall 212 of the sieving groove 21; the pressing plate 31 is fixedly buckled above the pressing plate 31, and the pressing plate 31 is pressed from top to bottom; the height adjusting screw is arranged below the pressure plate 31 and supports the pressure plate 31 upwards; the fixing buckle of the pressing plate 31 and the height adjusting screw clamp and fix the pressing plate 31 from the upper side and the lower side respectively. The height of the height adjusting screw relative to the first sieving plate 222 is adjusted by screwing in or out the height adjusting screw, thereby realizing the adjustment of the distance between the pressure plate 31 supported by the height adjusting screw and the first sieving plate 222.

As shown in fig. 1-4, as one example, the screening deck 22 has an inlet end 224 and an outlet end 225 disposed opposite one another, the space above the outlet end 225 communicates with the outlet 211, and the screening deck 22 slopes downwardly from the inlet section to the outlet end 225 to direct material on the screening deck 22 by gravity from the inlet end 224 toward the outlet end 225. Or as another embodiment, the sieving plate 22 has a feeding end 224 and a discharging end 225 which are oppositely arranged, a space on the discharging end 225 is communicated with the discharging port 211, and the sieving plate 22 guides the material on the sieving plate 22 to move from the feeding end 224 to the discharging end 225 in a vibration conveying mode.

As a specific example, as shown in fig. 1-2, the local vibratory screening apparatus further comprises a hopper 4, the hopper 4 being disposed above the feed end 224 of the first screening deck 222, the hopper 4 being loaded with material to be screened and being capable of continuously feeding the material to be screened towards the first screening deck 222 so that the screening portion 2 can continuously screen and separate the material to be screened.
