Description

Technical Field

[0001] This utility model belongs to the field of EPDM rubber granule production technology, and in particular relates to an EPDM rubber granule screening device. Background Technology

[0002] The EPDM rubber granule screening device is a specialized device for screening the particle size of EPDM (ethylene propylene diene monomer) granules. It is mainly used to separate finished granules of different sizes to meet the needs of different application scenarios.

[0003] Traditional EPDM rubber granule sieving devices typically use sieve plates to sieve fine particles in EPDM rubber granules to maintain the quality of the finished product. However, the sieve plates are usually set at an angle and vibrate during the sieving process, causing the EPDM rubber granules to move and be discharged quickly. This results in a large number of fine particles remaining inside the sieve, making the sieving incomplete and requiring rework. Utility Model Content

[0004] The purpose of this invention is to provide an EPDM rubber granule sieving device. A sieving box is placed on a sieve base, and the limiting block on the sieve box is inserted into the limiting rod. Then, EPDM rubber granules are poured into the sieve box. A motor is started, driving an elliptical disc to rotate, causing the sieve box to vibrate and thus perform sieving. This method ensures that the EPDM rubber granules remain inside the sieve box, preventing rapid discharge and ensuring more thorough sieving of fine particles. No rework is required afterward. This solves the problem that sieve plates are typically inclined and vibrate during sieving, causing EPDM rubber granules to move and discharge rapidly, leaving many fine particles unscreened.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a sieve for EPDM rubber granules, including a sieve base, a collection box positioned at the bottom of the sieve base, and a fixing base fixedly connected to the back of the sieve base, and further comprising: A sieving mechanism, located at the center of a sieve base, is used to sieve EPDM rubber granules. The sieving mechanism includes a sieve box located at the center of the sieve base. The bottom of the sieve box has multiple perforations. Several limiting blocks are fixedly connected to the outside of the sieve box. Each limiting block has a slidably connected limiting rod inside it. The bottom of the limiting rod is fixedly connected to the top of the sieve base. The limiting blocks and limiting rods cooperate to limit the movement of the sieve box, making its movement more stable. A turning mechanism is installed on the sieve box to turn over and scatter the accumulated EPDM rubber granules; handles are fixedly connected to the left and right sides of the sieve box, and a limiting block is inserted into the limiting rod to position the sieve box.

[0006] Furthermore, a motor is fixedly connected to the back of the fixed base, an elliptical disk is fixedly connected to the output end of the motor, and a convex plate is fixedly connected to the back of the sieve box, with the bottom of the convex plate contacting the surface of the elliptical disk; the dimensional deviation between the wide and narrow parts of the elliptical disk is small; due to the small dimensional deviation between the wide and narrow parts of the elliptical disk, the vibration amplitude of the sieve box is small.

[0007] Furthermore, a guide ring is fixedly connected to the bottom of the sieving box, and the guide ring is correspondingly set on the collection box. The collection box is used to collect the fine particles after sieving; the guide ring is used to guide the fine particles after sieving.

[0008] Furthermore, the turning mechanism includes a bracket fixedly connected to the sieve box, a top shell fixedly connected to the top of the bracket, a rotating rod rotatably connected inside the bracket, a plurality of turning rods fixedly connected to the outer surface of the rotating rod, and an inclined strip fixedly connected to the bottom of the turning rod located at the bottom; the rotating rod and the turning rod are located at the center of the sieve box, the turning rod is a round rod, the bottom of the inclined strip has a small gap with the bottom of the inner side of the sieve box, and the inclined strip is inclined; the inclined strip on the bottom turning rod will scoop up the EPDM rubber particles at the bottom of the sieve box, thereby turning over the EPDM rubber particles accumulated at the bottom.

[0009] Furthermore, a support is fixedly connected to the top of the bracket, and a second motor is fixedly connected to the top of the support. Gears are fixedly connected to both the output end of the second motor and the top of the rotating rod. The two gears mesh together, and the rotating rod serves to shield and protect the shaft. The two gears transmit the power of the second motor to the rotating rod, thereby causing the rotating rod to rotate slowly.

[0010] Furthermore, a large circular hole is provided on the top of the sieve base, and the sieve box is located inside the large circular hole on the sieve base.

[0011] This utility model has the following beneficial effects: This invention features a sieving mechanism. Specifically, a sieving box is placed on a sieve base, and the limiting block on the sieving box is inserted into the limiting rod. Then, EPDM rubber granules are poured into the sieving box. By starting a motor, the elliptical disc is rotated, causing the sieving box to vibrate, thereby performing the sieving process. This method ensures that the EPDM rubber granules remain inside the sieving box, preventing them from being discharged quickly and allowing for more thorough sieving of fine particles within the EPDM rubber granules, eliminating the need for subsequent rework. This invention features a flipping mechanism, specifically a rotating rod that drives several flipping rods to rotate together, thereby flipping the EPDM rubber particles in the sieve box and improving the screening effect. Furthermore, the inclined bars on the bottom flipping rods scoop up the EPDM rubber particles at the bottom of the sieve box, thus flipping the accumulated EPDM rubber particles at the bottom and further improving the screening effect. This method can break up the stacked EPDM rubber particles, allowing the fine particles inside to be screened more effectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 As shown, this utility model is a sieve for EPDM rubber granules, including a sieve base 1, a collection box 11 positioned at the bottom of the sieve base 1, and a fixing seat 12 fixedly connected to the back of the sieve base 1, and also including: The sieving mechanism 2 is located at the center of the sieve base 1. The sieving mechanism 2 is used to sieve EPDM rubber granules. The sieving mechanism 2 includes a sieve box 21 located at the center of the sieve base 1. The bottom of the sieve box 21 has multiple perforations. Several limiting blocks 23 are fixedly connected to the outside of the sieve box 21. Each limiting block 23 has a slidably connected limiting rod 24 inside it. The bottom of the limiting rod 24 is fixedly connected to the top of the sieve base 1. Sieving is performed by vibrating the sieve box 21. This method ensures that the EPDM rubber granules remain within the sieve box 21, preventing rapid discharge of the EPDM rubber granules and allowing for more thorough sieving of fine particles, eliminating the need for subsequent rework. The turning mechanism 3 is installed on the sieve box 21 and is used to turn over and scatter the accumulated EPDM rubber granules. The sieve box 21 has handles 22 fixedly connected to both the left and right sides, and the limiting block 23 is inserted into the limiting rod 24 to position the sieve box 21.

[0018] A motor 121 is fixedly connected to the back of the fixed base 12, and an elliptical disk 122 is fixedly connected to the output end of the motor 121. A convex plate 25 is fixedly connected to the back of the sieve box 21, and the bottom of the convex plate 25 is in contact with the surface of the elliptical disk 122. Among them, the dimensional deviation between the wide and narrow parts of the elliptical disk 122 is relatively small.

[0019] A guide ring 26 is fixedly connected to the bottom of the sieving box 21. The guide ring 26 is correspondingly set on the collection box 11, which is used to collect the fine particles after sieving.

[0020] The turning mechanism 3 includes a bracket 31 fixedly connected to the sieve box 21. A top shell 32 is fixedly connected to the top of the bracket 31. A rotating rod 33 is rotatably connected inside the bracket 31. Several turning rods 331 are fixedly connected to the outer surface of the rotating rod 33. An inclined bar 332 is fixedly connected to the bottom of the turning rod 331. The rotating rod 33 drives the several turning rods 331 to rotate together, thereby turning over the EPDM rubber particles in the sieve box 21 and improving the screening effect. In addition, the inclined bar 332 on the bottom turning rod 331 will scoop up the EPDM rubber particles at the bottom of the sieve box 21, thereby turning over the EPDM rubber particles accumulated at the bottom and further improving the screening effect. This method can break up the stacked EPDM rubber particles, so that the fine particles inside can be screened better. A small gap is left between the bottom of the inclined bar 332 and the bottom of the inner side of the sieve box 21. The inclined bar 332 is set at an inclination. The rotating rod 33 and the flipping rod 331 are located at the center of the sieve box 21, and the flipping rod 331 is a round rod.

[0021] A support 34 is fixedly connected to the top of the bracket 31, and a second motor 35 is fixedly connected to the top of the support 34. Gears 333 are fixedly connected to the output end of the second motor 35 and the top of the rotating rod 33. Among them, two gears 333 mesh together, and the rotating rod 33 is used to shield and protect.

[0022] A large round hole is provided on the top of the sieve base 1, and the sieve box 21 is located in the large round hole on the sieve base 1.

[0023] One specific application of this embodiment is: In use, place the sieve box 21 on the sieve base 1, and insert the limiting block 23 on the sieve box 21 into the limiting rod 24 to position the sieve box 21. After the sieve box 21 is placed, the protruding plate 25 will contact the elliptical disk 122. Then, place the collection box 11 inside the sieve base 1, and pour the EPDM rubber granules into the sieve box 21. At this time, start the motor 121 to drive the elliptical disk 122 to rotate. Since the elliptical disk 122 is elliptical, it will push the sieve box 21 upward through the protruding plate 25. The sieve box 21 is then reset downwards by gravity, and the limiting block 23 slides on the limiting rod 24. This process is repeated, and the sieve box 21 vibrates up and down. The dimensional deviation between the wide and narrow parts of the ellipse of the elliptical disk 122 is small, so the vibration amplitude of the sieve box 21 is small. Through the vibration of the sieve box 21, the fine particles remaining in the EPDM rubber granules can be quickly screened out, and the fine particles will enter the collection box 11 for collection. The guide ring 26 is used to guide the fine particles to enter the collection box 11 smoothly for collection. During screening, motor 2 35 is started, driving the front gear 333 to rotate. The front gear 333 then drives the rear gear 333 to rotate. At this time, the rotating rod 33 drives several turning rods 331 to rotate together, thereby turning over the EPDM rubber particles in the screening box 21, improving the screening effect. In addition, the inclined strips 332 on the bottom turning rods 331 will scoop up the EPDM rubber particles at the bottom of the screening box 21, thereby turning over the EPDM rubber particles accumulated at the bottom, further improving the screening effect. Finally, when screening is completed, motor 2 35 and motor 1 121 are stopped, and the screening box 21 stops vibrating. Then, by pulling the handle 22, the screening box 21 is pulled upward to remove and disassemble, and the screened EPDM rubber particles can be poured out and collected.
