Description

Technical Field

[0001] This utility model belongs to the field of rubber compounding technology, and in particular relates to an NBR rice hulling rubber roller compounding device. Background Technology

[0002] The rubber layer of rice hulling rollers is usually made of nitrile rubber (NBR) as the main material, with the addition of reinforcing agents, antioxidants, plasticizers and other auxiliary materials. After mixing, it is wrapped around the iron core of the roller and vulcanized. During rubber compounding, a certain temperature is maintained to reduce the viscosity of the rubber, facilitating the wetting and dispersion of auxiliary materials. After compounding, the rubber still maintains a certain temperature. To facilitate worker operation, the sheeting device is kept at a considerable distance from the open mill. During sheeting, the uncooled rubber sheets are relatively soft and will be stretched and deformed due to gravity. A certain amount of deformation needs to be reserved during production to ensure the size of the cooled rubber sheets. A large amount of dust is easily generated during the compounding process in the open mill. Conventional release agent soaking tanks need to be covered to keep the release agent soaking tank clean, and the opening procedure is cumbersome when sheeting. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an NBR rice hulling rubber roller mixing device, which can reduce the problem of rubber sheets being stretched and deformed by gravity during the conveying process due to excessive distance between the front roller and the sheeting device, and improve the cleanliness of the release agent soaking tank.

[0004] The NBR rice hulling rubber mixing apparatus according to an embodiment of the present invention includes: A rubber mixing mill uses two rollers rotating at different speeds to rub and shear the rubber material. The rubber material and additives are stretched, folded, and squeezed together evenly. During mixing, the rubber material is wrapped around the front roller. The sheeting device is located on the front roll side of the rubber open mill and includes a frame, a first conveying section and a second conveying section with multiple drive rollers built into the top of the frame, and a release agent soaking tank located inside the frame below the first conveying section. A first telescopic mechanism is provided between the first conveying part and the frame. When the first telescopic mechanism extends, it pushes the first conveying part closer to the rubber open mill, while simultaneously releasing the release agent soaking tank.

[0005] The NBR rice hulling rubber roller mixing apparatus according to the embodiments of the present invention has at least the following beneficial effects: A sheeting device is provided on one side of the front roll of the rubber open mill. The first conveying part on the sheeting device can approach the front roll of the rubber open mill through the first telescopic mechanism, which shortens the distance between the front roll and the sheeting device. This reduces the problem of the rubber sheet being stretched and deformed by gravity during the conveying process due to the excessive distance between the front roll and the sheeting device. The telescopic first conveying part also ensures that the workers have a wider operating space when operating the open mill. The release agent soaking tank is located inside the frame below the first conveyor section. The first conveyor section essentially forms a cover for the release agent soaking tank, effectively preventing foreign objects from entering the tank. Furthermore, the first conveyor section opens when the rubber sheet exits, without affecting the use of the release agent soaking tank.

The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] This utility model embodiment proposes an NBR rice hulling rubber roller mixing device, which mainly includes a rubber open mill-1 and a sheeting device. The rubber open mill-1 uses two rollers rotating at different speeds to rub and shear the rubber material. The rubber material and additives are stretched, folded, and squeezed together evenly. During mixing, the rubber material is wrapped on the front roller-11. The sheeting device is located on one side of the front roller-11 of the rubber open mill-1 and includes a frame-2, a first conveying part-3 and a second conveying part-4 located at the top of the frame-2 with multiple drive rollers-32 built in, and a release agent soaking tank-5 located inside the frame-2 below the first conveying part-3. A first telescopic mechanism-6 is provided between the first conveyor section-3 and the frame-2. When the first telescopic mechanism-6 extends, it pushes the first conveyor section-3 closer to the rubber open mill-1, and at the same time, the release agent soaking tank-5 is exposed.

[0023] It is understandable that a sheeting device is provided on one side of the front roller-11 of the rubber open mill-1. The first conveying part-3 on the sheeting device can approach the front roller-11 of the rubber open mill-1 through the first telescopic mechanism-6, which shortens the distance between the front roller-11 and the sheeting device. This reduces the problem of the rubber sheet being stretched and deformed by gravity during the conveying process due to the excessive distance between the front roller-11 and the sheeting device. The release agent soaking tank-5 is located inside the frame-2 below the first conveying part-3. The first conveying part-3 essentially forms a cover for the release agent soaking tank-5, effectively preventing foreign objects from entering the tank. Moreover, the first conveying part-3 is opened when the rubber sheet is sheeted, without affecting the use of the release agent soaking tank-5.

[0024] In this embodiment, the first conveying part-3 slides on the frame-2 via a slide rail, and the movable end of the first telescopic mechanism-6 is connected to the side plate at the end of the first conveying part-3.

[0025] In this embodiment, the first conveying unit-3 further includes a first power unit-21 disposed on the frame-2. After the first conveying unit-3 is pushed into place, one of the transmission rollers-32 on the first conveying unit-3 is coupled with the first power unit-21 to drive the conveying surface-31 to work.

[0026] In this embodiment, the first power unit-21 includes a motor-211 and a drive gear-212 that is fixed on the side plate of the frame-2 by the motor-211. The transmission roller-32 on the first transmission part-3, which is coupled to the first power unit-21, has a driven gear-33 at its end that meshes with the drive gear-212. When the first transmission part-3 is pushed to the set position, the drive gear-212 and the driven gear-33 mesh, and the first power unit-21 provides power to the first transmission part.

[0027] In this embodiment, a lowering mechanism 7 is provided on the upper part of the conveying surface 31 near the front roller 11 of the first conveying section 3. The lowering mechanism 7 includes a double-layer support frame 71 mounted on the side plate of the first conveying section 3. The lower layer of the double-layer support frame 71 is equipped with a guiding mechanism, and the upper layer of the double-layer support frame 71 is equipped with a transverse cutting mechanism. The guiding mechanism includes a second telescopic mechanism-72 installed on the lower layer of the double-layer support frame-71, and a guide roller-73 installed on the movable end of the second telescopic mechanism-72. The guide roller-73 has multiple grooves-74 on its roller surface. When the sheet is unloaded, the guide roller-73 abuts against the rubber sheet of the front roller-11 of the open mill. The grooves-74 increase the adhesion of the guide roller-73 to the rubber sheet. The cross-cutting mechanism includes a third telescopic mechanism-76 installed on the upper layer of the double-layer support frame-71, and a cross-cutting roller-77 installed on the movable end of the third telescopic mechanism-76. The cross-cutting roller-77 has an outwardly protruding cross-cutting blade-78 on its roller surface. When the sheet is unloaded, the cross-cutting roller-77 abuts against the rubber sheet of the front roller-11 of the open mill and is driven to rotate passively by the rubber sheet. When it rotates to the cross-cutting blade-78, it cuts the rubber sheet.

[0028] The cross-cutting roller-77 is equipped with a limiting structure, which ensures that the cross-cutting blade-78 is above the roller body before each operation of the cross-cutting roller-77.

[0029] Preferably, the limiting structure is a counterweight block set at the relative position of the cross-cutting blade-78 inside the cross-cutting roller-77.

[0030] In this embodiment, the guide roller-73 is driven to rotate relative to the front roller-11 by the guide motor-75 installed at the movable end of the third telescopic mechanism-76, thereby improving the adhesion of the guide roller-73 to the rubber sheet.

[0031] In this embodiment, a vertical cutting mechanism-8 is provided at the lower part of the conveying surface-31 near the front roller-11 end of the first conveying section-3. The vertical cutting mechanism-8 includes a support frame-81 mounted under the side plate of the first conveying section-3, a fourth telescopic mechanism-82 mounted on the support frame-81, and two vertical cutting blades-83 mounted on the movable end of the fourth telescopic mechanism-82.

[0032] In this embodiment, the distance between the two vertical cutting blades-83 is adjustable, and there are two sets of fourth telescopic mechanisms-82. The width of the rubber sheet can be changed by adjusting the distance between the two sets of fourth telescopic mechanisms.

[0033] In another implementation, the movable end of the fourth telescopic machine is provided with an adjustment frame, and the vertical cutting blade-83 is installed on the adjustment frame. The width of the rubber sheet is changed by adjusting the width of the adjustment frame.

[0034] In another implementation, the vertical cutting mechanism-8 is located at the bottom of the front roller-11 of the rubber open mill-1.

[0035] In this embodiment, the second conveying section-4 is disposed on the opposite side of the first conveying section-3 on the top of the frame-2. The second conveying section-4 also includes a second power unit-22 disposed on the frame-2. One of the transmission rollers of the second conveying section-4 is coupled with the second power unit-22 to drive the conveying surface to work.

[0036] In this embodiment, the release agent soaking tank-5 is equipped with guide rollers to guide the rubber sheet.

[0037] The NBR rice hulling rubber roller mixing unit has the following different application scenarios: In one scenario, the rubber open mill-1 completes mixing, the first telescopic mechanism-6 extends, pushing the first conveyor-3 closer to the rubber open mill-1, while simultaneously releasing the release agent soaking tank-5; after the first conveyor-3 is pushed to the set position, the driving gear-212 and the driven gear-33 mesh, and the first power unit-21 provides power to the first transmission unit; the fourth telescopic mechanism-82 extends, passing the vertical cutting blade-83 through the rubber sheet and pressing it against the front roller-11, where the vertical cutting blade-83 cuts the rubber sheet to a set width; the second telescopic mechanism-72 and the third telescopic mechanism-76 extend, causing the guide roller-73 and the cross-cutting roller-77 to abut against the front roller-11 of the open mill. On the rubber sheet, the guide roller-73 and the cross-cutting roller-77 rotate passively with the rubber sheet. When the cross-cutting roller-77 rotates to the position of the cross-cutting blade-78, it cuts the rubber sheet. The guide roller-73 continues to provide tension on the rubber sheet by the guide motor-75. The second telescopic mechanism-72 and the third telescopic mechanism-76 retract, and the guide motor-75 rotates in the opposite direction, causing the rubber sheet to fall onto the conveying surface-31 of the first conveying section-3. The rubber sheet enters the release agent soaking tank-5 through the first conveying section-3. After passing through the guide roller in the release agent soaking tank-5, the worker sends the rubber sheet into the second conveying section-4. The rubber sheet is then sent through the second conveying section-4 to the subsequent air cooling, cutting and other subsequent steps.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
