Description

Technical Field

[0001] The utility model belongs to the technical field of styrene-butadiene rubber production, in particular to a feeding device for styrene-butadiene rubber production. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce a large deformation under a small external force, and can return to its original shape after the external force is removed. When the existing feeding device for rubber product production is in use, the raw materials used for rubber product production are easily stuck due to the presence of moisture on the surface, thereby blocking the discharge port of the feeding device, which reduces the working efficiency of the feeding device for rubber product production to a certain extent. Therefore, some existing rubber feeding devices have drying and anti-sticking structures.

[0003] For example, patent application number CN202222296481.8 discloses a feeding device for rubber product production, including a processing box, characterized in that: a feeding port is provided at the upper end of the processing box, a drying box is connected to the upper side wall of the processing box through a support rod, a feeding pipe is connected to the upper end of the drying box, a support frame is also fixedly provided at the upper end of the drying box, a motor is installed at the upper end of the support frame, a rotating shaft is connected to the motor output shaft, the other end of the rotating shaft rotates and extends into the interior of the drying box, and a plurality of stirring rods are connected to the outer side wall. The advantage is that: before the rubber raw material particles enter the processing box, a drying box is set, and the rubber raw material particles inside the drying box can be dried by providing power through the motor. At the same time, the motor can also make the hose reciprocate left and right, and the hose will evenly spread the rubber raw material particles into the processing box, thereby avoiding the accumulation of raw materials, which is beneficial to improving the processing effect of the raw materials.

[0004] The existing technology uses a drying box to pre-dry the rubber raw material particles and sets a hose to avoid the accumulation and adhesion of the raw materials. However, it still has certain shortcomings: when the rubber raw materials are stacked in the early stage, a large amount of dust and dirt are easily adhered to the surface. If they are directly discharged into the processing box for fusion treatment, the rubber molding quality will be seriously affected. Although the existing technology can avoid the adhesion and accumulation of rubber, it is unable to remove the dust and dirt and unable to improve the rubber molding quality. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a feeding device for styrene-butadiene rubber production. The utility model not only allows a variety of raw materials to be bonded and separated before feeding, but also allows efficient dust and slag removal, effectively improving the molding quality of the rubber, through the arrangement of a conical screen plate, an elastic scraper, a vibration motor, and an arc-surface elastic plate.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device for the production of styrene-butadiene rubber, comprising a barrel, a first pipe opening, a first pipe opening arranged on the top end surface of the barrel, a conical screen plate arranged inside the barrel below the first pipe opening, a plurality of vibration motors evenly arranged along the circumferential direction on the inner wall of the barrel below the conical screen plate, a connecting plate connected to the output end of the vibration motor, the connecting plate and the conical screen plate are connected to each other, a slag discharge pipe is arranged below the conical screen plate, the slag discharge pipe is connected to the conical screen plate through an elastic pipe, and a downwardly curved elastic plate is arranged on the outer side of the slag discharge pipe on the inner circular surface of the barrel. The arrangement of the conical screen plate and the curved elastic plate allows the bonded raw materials to not only be separated but also to be dusted and slag removed, effectively improving the molding quality of the rubber.

[0007] Preferably, a connecting sleeve is rotatably arranged above the conical screen plate, a plurality of connecting rods are evenly arranged on the outer circumferential surface of the connecting sleeve in the circumferential direction, a plurality of elastic strips are arranged on the bottom end surface of the connecting rod, an elastic scraper is connected to the bottom of the elastic strip, and the elastic scraper is rotatably fitted to the end surface of the conical screen plate. The setting of the elastic scraper effectively improves the screening efficiency of the conical screen plate for rubber raw materials.

[0008] Preferably, a conical cover plate is fixed in the cylinder body above the conical screen plate, a first drive motor is arranged at the bottom of the conical cover plate, and an output end of the first drive motor is connected to the connecting sleeve.

[0009] Preferably, a plurality of convex strips are arranged on the cambered surface of the cambered elastic plate, and the arrangement of the convex strips effectively improves the throwing effect on the raw materials and improves the separation effect on the bonded raw materials.

[0010] Preferably, a plurality of bent elastic rods are arranged between the arc surface elastic plate and the inner wall of the cylinder body. The arrangement of the plurality of bent elastic rods effectively improves the strength and elasticity of the arc surface elastic plate.

[0011] Preferably, a second driving motor is fixedly disposed in the slag discharge pipe, and a rotating impeller is connected to the output end of the second driving motor.

[0012] Preferably, a second pipe opening is provided on the bottom end surface of the barrel.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] The utility model arranges the conical screen plate, the rotating fan wheel, the elastic strip and the vibration motor, so that the accumulated raw materials can be spread out and dispersed on the outer surface of the conical screen plate for vibration screening after entering the cylinder body, so that the dirt and debris on the surface of the rubber raw materials can be fully screened and dust can be avoided, which not only improves the rubber molding quality but also ensures a good processing environment.

[0015] The utility model uses the arrangement of a vibration motor, an arc elastic plate, a convex strip, and a bent elastic rod, so that the raw materials can not only be screened and dusted, but also can be tossed during and after the screening process, so that part of the raw materials that are bonded can be dispersed, thereby effectively improving the subsequent feeding efficiency and avoiding the blockage of the discharge port.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0024] refer to Figure 1-7 A feeding device for producing styrene-butadiene rubber comprises a barrel 51 and a first pipe opening 52. The first pipe opening 52 is arranged on the top end surface of the barrel 51, a conical sieve plate 55 is arranged in the barrel 51 below the first pipe opening 52, a plurality of vibration motors 64 are evenly arranged along the circumferential direction on the inner wall of the barrel 51 below the conical sieve plate 55, a connecting plate 69 is connected to the output end of the vibration motor 64, the connecting plate 69 and the conical sieve plate 55 are connected to each other, a slag discharge pipe 61 is arranged below the conical sieve plate 55, the slag discharge pipe 61 and the conical sieve plate 55 are connected by an elastic cloth pipe 54, and a downwardly curved arc elastic plate 58 is arranged on the inner circular surface of the barrel 51 outside the slag discharge pipe 61.

[0025] Before work, the staff can install the barrel 51 at the feed port or discharge port of the batching machine. The barrel 51 can remove dust and dirt in the rubber material particles. The rubber material will enter the barrel 51 through the first pipe port 52. The rubber material entering the barrel 51 will fall onto the conical surface of the conical screen plate 55. The surface of the conical screen plate 55 has multiple holes. The rubber particles falling on the conical screen plate 55 will automatically disperse and roll outward under the influence of the conical surface of the conical screen plate 55. During this process, the output end of the vibration motor 64 will vibrate, so that the connecting plate 69 can be vibrated, so that the conical screen plate 55 can be vibrated, so that the rubber material scattered on the conical screen plate 55 can be vibrated, so that the dust and dirt on the surface of the rubber material or small useless particles can be sieved through the holes on the surface of the conical screen plate 55, and the sieved dirt will be collected by the elastic cloth tube 54, and then discharged outward through the slag discharge pipe 61.

[0026] The screened rubber material will fall onto the curved elastic plate 58. During this process, the curved elastic plate 58 will generate a certain vibration, and the rubber material will be thrown downward to the bottom of the cylinder body 51, so that the rubber material that may be adhered can be broken up by the impact of the fall, reducing the occurrence of subsequent adhesion. The rubber material that falls to the bottom of the cylinder body 51 will be discharged later.

[0027] refer to Figure 6 A connecting sleeve 68 is rotatably provided above the conical screen plate 55, and a plurality of connecting rods 65 are evenly provided on the outer circumferential surface of the connecting sleeve 68 along the circumferential direction. A plurality of elastic strips 67 are provided on the bottom end surface of the connecting rod 65, and an elastic scraper 66 is connected to the bottom of the elastic strip 67, and the elastic scraper 66 is rotatably fitted to the end surface of the conical screen plate 55.

[0028] When the rubber material rolls on the surface of the conical screen plate 55, the connecting sleeve 68 will rotate, thereby driving the multiple connecting rods 65 and the elastic strips 67 and the elastic scraper 66 to rotate. The rotating elastic scraper 66 will rotate in contact with the outer surface of the conical screen plate 55. On the one hand, this rotation can spread out the rubber material that may be accumulated somewhere on the conical screen plate 55 to improve the screening efficiency. On the other hand, it can push away the rubber material blocking the holes on the surface of the conical screen plate 55, so that the screening can proceed smoothly.

[0029] refer to Figure 4 A plurality of convex strips 59 are arranged on the arc surface of the arc elastic plate 58 .

[0030] The plurality of convex strips 59 can increase the rolling frequency of the rubber material on the arc surface of the arc elastic plate 58, thereby improving the separation effect.

[0031] refer to Figure 4 A plurality of bent elastic rods 60 are arranged between the arc elastic plate 58 and the inner wall of the cylinder body 51 .

[0032] The plurality of bent elastic rods 60 are all made of elastic material, and can support the arc surface elastic plate 58 while improving the bouncing effect of the arc surface elastic plate 58, thereby improving the throwing efficiency of the rubber material.

[0033] refer to Figure 4 A second pipe opening 53 is provided on the bottom end surface of the barrel body 51 .

[0034] The second nozzle 53 can discharge the rubber material dropped to the bottom of the barrel 51 outward.

[0035] refer to Figure 4 A conical cover plate 56 is fixed in the cylinder body 51 above the conical screen plate 55 , and a first drive motor 57 is arranged at the bottom of the conical cover plate 56 . The output end of the first drive motor 57 is connected to the connecting sleeve 68 .

[0036] The top of the conical cover plate 56 is in a conical shape, and the rubber material can be evenly distributed to various places on the conical screen plate 55. The output end of the first driving motor 57 can drive the connecting sleeve 68 to rotate. Embodiment 2:

[0037] On the basis of or different from the first embodiment, reference Figure 4 A second driving motor 62 is fixedly arranged in the slag discharge pipe 61 , and a rotating impeller 63 is connected to the output end of the second driving motor 62 .

[0038] When the slag discharge pipe 61 discharges the waste slag dust, the output end of the second drive motor 62 can drive the rotating fan wheel 63 to rotate, which can drive the gas above the conical screen plate 55 to flow downward. On the one hand, it can improve the slag discharge efficiency, and on the other hand, it can suck downward the dust generated during the vibration screening process of the conical screen plate 55, reducing the possibility of dust flowing outward through the first pipe opening 52, thereby ensuring a good processing environment.
