Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The first embodiment is as follows:
as shown in fig. 1-2, the present embodiment provides a forced feeding device for a rubber extruder, which comprises a feeding base 1, a feeding roller assembly 3, a feeding gate 4, a bushing 5, a screw 2, and a doctor blade 6. Wherein, the feeding seat body 1 is connected with the feeding door 4 in a hinged mode, a feeding hole for rubber materials to enter the feeding device is arranged above the feeding seat body 1 and the feeding door 4, and when the feeding door 4 is opened, the feeding roller assembly 3 arranged on the feeding seat body can be detached or maintained. A replaceable lining 5 is embedded in the feeding base body 1, a screw rod 2 extending along the material conveying direction is arranged in the feeding base body and penetrates through the inner cavity of the lining 5, and threads extend from a feeding port to a discharging port and reach the front end of a machine head; a feeding roller component 3 is arranged in the feeding door 4; the feeding roller assembly 3 comprises a left bearing seat 7, a left glue returning ring 8, a feeding roller 9, a right glue returning ring 10, a right bearing seat 11, a first gear 12 and the like, wherein the first gear 12 is meshed with a second gear 12 which is arranged on the screw rod 2 and driven by power, and the second gear 12 is driven to rotate, so that part of the power is transmitted to the feeding roller 9 through the first gear 12 arranged in the feeding roller assembly 3, the screw rod 2 and the roller surface of the feeding roller 9 generate meshing motion, and glue above a feeding port is pulled into the lining 5; preferably, the screw 2 is mounted on an output shaft of a speed reducer, and the speed reducer sequentially transmits the torque output by the motor to the screw 2 and the feed roller 9. In the embodiment, the screw 2, the feeding roller 9 and the lining 5 are provided with the cooling water channels, so that the distance between the water channels and the sizing material is reduced, and the heat exchange efficiency between the cooling water channels and the sizing material can be improved; meanwhile, the problem of water leakage caused by the defect of a casting when the water channel is arranged on the feeding base body is solved.
As shown in fig. 2, the lower part of the feeding base 1 is provided with a doctor blade 6, and the gap between the doctor blade 6 and the feeding roller 9 can be adjusted. The screw 2 rotates to drive the feeding roller assembly 3 to rotate together through the first gear 12 and the second gear 13. The inner wall of the bushing 5 is designed with a large-lead rubber guide thread, so that rubber entering the feeding device can rapidly move forwards along the rubber guide thread. When the rubber enters the feeding opening, the rubber is extruded by the feeding roller 9, the rubber enters the screw groove of the screw 2 and the rubber guide thread of the bushing 5, and the rubber rapidly moves forward along the screw groove and the rubber guide thread along with the rotation of the screw 2. When the glue reaches the position of the doctor blade 6, the doctor blade 6 scrapes the glue off the surface of the feed roller 9, and a large amount of glue enters the liner 5 along the rotation of the screw.
As shown in FIG. 2, a line connecting the center of the screw 2 and the center of the feeding roller 9 forms an angle a with the horizontal plane to ensure that the rubber material enters the screw groove of the screw rapidly under the pushing force of the feeding roller after entering the feeding port, and the rubber material moves forward along with the rotation of the screw, thereby reducing the rubber return of the feeding port and the extrusion temperature of the rubber material. A reasonably preferred angle is between 10 ° and 22 °.
In this embodiment, the linear velocity of the surface of the screw 2 is slightly lower than the linear velocity of the surface of the feeding roller 9, so that after the rubber material is fed into the feeding port, the feeding roller 9 has a certain extrusion acting force on the rubber material, and the rubber material smoothly enters the extruder. The reasonable speed ratio is 1: 1-1: 1.3, preferably 1: 1.05 to 1: 1.2.
In this embodiment, as shown in fig. 2, the distance between the center of the screw 2 and the center of the feeding roller 9 is within a reasonable range, so that the glue feeding effect of the extruder can be ensured, when the distance between the screw 2 and the feeding roller 9 is too small, the glue extruding screw 2 and the feeding roller 9 generate huge pressure, so that the glue feeding is difficult, and even the equipment is damaged, if the distance between the screw 2 and the feeding roller is too large, after the glue enters the feeding port, the feeding roller 9 cannot form an extruding force on the glue, so that the glue is not easy to enter the screw groove, and the glue returning phenomenon is easy to occur at the feeding port. The distance L between the surface of the feed roller 9 and the surface of the screw 2 may be 10 to 50mm, preferably 15 to 35 mm.
By adopting the forced feeding device of the extruder, the technical problems of water leakage of the feeding device, unsmooth glue eating at a feeding port, serious glue return, reduced output of the extruder, higher glue temperature of extruded glue materials and the like are solved.
Meanwhile, after the rubber material enters the feeding port, the rubber material smoothly enters the feeding device and the screw groove of the screw rod under the extrusion of the feeding roller, and moves forwards quickly along with the rotation of the screw rod, so that the rubber feeding efficiency of the extruder is improved, the rubber return quantity at the feeding port is reduced, the extrusion temperature of a product is reduced, and the utilization efficiency of equipment is improved. The problem of the water leakage of the feeding seat is solved, the maintenance times and the maintenance cost of equipment are reduced, and the labor intensity of workers is reduced.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
