Description

Technical Field

[0001] This invention belongs to the field of weighing equipment, and particularly relates to a rubber additive weighing and batching device. Background Technology

[0002] Rubber additives, originating from the vulcanization of natural rubber, underwent over eighty years of research. It wasn't until the 1920s and 30s, with the industrialization of basic vulcanization accelerators like 2-mercaptobenzothiazole and its sulfenamide derivatives, as well as p-phenylenediamine antioxidants, that a basic system of rubber additives was formed. Rubber additives are currently in a stable period, with the production of the two main organic additives—vulcanization accelerators and antioxidants—accounting for approximately 4% of raw rubber consumption.

[0003] Existing rubber additives require precise weighing before use, but if multiple portions of the same weight are needed, multiple weighings are required, which is inconvenient. Summary of the Invention

[0004] To address the aforementioned problem of requiring multiple weighings, this invention provides a rubber additive weighing and dispensing device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a rubber additive weighing and dispensing device, comprising a weighing device and a dispensing device; the weighing device includes a table, a screw jack fixedly connected below the table, the screw jack including a screw passing through the table and a base rotatably connected to the upper end of the screw, an electronic scale fixedly connected above the base, a first bracket fixedly connected above the electronic scale, a first collar fixedly connected in the middle of the first bracket, a receiving cup sleeved inside the first collar, the receiving cup including a cup body and a separator for evenly distributing and separating the material inside the cup; the dispensing device includes a miniature screw feeder, a fixed base fixedly connected below the miniature screw feeder, an electric push rod fixedly connected below the fixed base, a rotating shaft fixedly connected below the electric push rod, a base plate rotatably connected below the rotating shaft, a driven bevel gear fixedly connected in the middle of the rotating shaft, the driven bevel gear meshing with a transmission rod, a drive bevel gear meshing with the end of the transmission rod away from the driven bevel gear, and a drive motor fixedly connected below the drive bevel gear.

[0006] Preferably, a telescopic column for enhancing the stability of the electronic scale is connected between the table and the electronic scale. The telescopic column includes a column body and a column slidably connected to the column body.

[0007] Preferably, a second bracket is fixedly connected above the table, and a second collar is fixedly connected to the middle of the second bracket. The second collar is positioned directly above the first collar, and the second collar and the first collar together fit over the receiving cup.

[0008] Preferably, the diameter of the second ring is larger than that of the first ring, and the outer diameter of the cup body gradually decreases from top to bottom.

[0009] Preferably, an extension arm is fixedly connected to one side of the fixed base, a stirring motor is fixedly connected above the extension arm, and the stirring motor is fixedly connected to stirring teeth for leveling the material in the receiving cup through the extension arm.

[0010] Preferably, the separator includes a cover with a notch, and a plurality of baffles are rotatably connected below the cover, the baffles being distributed in a ring at equal intervals around the center of the cover.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The present invention uses an electronic scale in the weighing device to weigh the receiving cup and the material inside the receiving cup, and then uses a micro screw feeder to supply the material into the receiving cup. The material supply using the micro screw feeder is easy to control. At the same time, the drive motor drives the micro screw feeder to rotate through a series of transmission components, so that the micro screw feeder can be moved away from the top of the receiving cup, making it easy to remove the receiving cup. The receiving cup includes a divider. After the material is weighed, the divider is inserted into the cup body from top to bottom, which can divide the material in the cup body into several equal parts, avoiding multiple weighings.

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a rubber additive weighing and batching device 2 is provided. In order to prepare several portions of rubber additives with the same mass and avoid multiple weighings, the present invention includes a weighing device 1 and a batching device 2. The weighing device 1 includes a table 11, and a screw jack 12 is fixedly connected below the table 11. The screw jack 12 can be widely used in various industries such as machinery, metallurgy, construction, chemical industry, medical, culture and health. The lifting or pushing height can be accurately controlled and adjusted according to a certain procedure. It can be directly driven by an electric motor or other power, or it can be manually driven. The screw jack 12 includes a screw 121 passing through the table 11 and a base 122 rotatably connected to the upper end of the screw 121. An electronic scale 13 is fixedly connected above the base 122. The screw jack 12 can drive the electronic scale 13 to move up and down. A first bracket 17 is fixedly connected above the electronic scale 13. A first collar 171 is fixedly connected in the middle of the first bracket 17. A receiving cup is sleeved inside the first collar 171. The electronic scale 13 can weigh the receiving cup and the material in the receiving cup. The receiving cup includes a cup body 14 and a divider 15 for evenly distributing and separating the material in the cup body 14. The divider 15 is used to divide the material in the receiving cup into several equal parts.

[0019] In this invention, the feeding device 2 includes a miniature screw feeder 21. Screw feeders are common equipment and will not be described in detail. In this invention, the miniature screw feeder 21 is used to supply material to the receiving cup. A fixed base 22 is fixedly connected below the miniature screw feeder 21, which supports the miniature screw feeder 21. An electric push rod 23 is fixedly connected below the fixed base 22. The electric push rod 23, also known as a linear actuator, is a novel linear actuator mainly composed of a motor, push rod, and control device. In this invention, the electric push rod 23 is used to drive the fixed base 22 to move up and down. A rotating shaft 24 is fixedly connected below the electric push rod 23. A base plate 242 is rotatably connected below the rotating shaft 24. A driven bevel gear 241 is fixedly connected in the middle of the rotating shaft 24. The driven bevel gear 241 meshes with a transmission rod 25. The end of the transmission rod 25 away from the driven bevel gear 241 meshes with a driving bevel gear 261. A drive motor 26 is fixedly connected below the driving bevel gear 261. The drive motor 26 drives the micro screw feeder 21 to rotate.

[0020] Specifically, the present invention uses an electronic scale 13 in the weighing device 1 to weigh the receiving cup and the material inside the receiving cup, and then uses a micro screw feeder 21 to supply the material into the receiving cup. The material supply using the micro screw feeder 21 is easy to control. At the same time, the drive motor 26 drives the micro screw feeder 21 to rotate through a series of transmissions, so that the micro screw feeder 21 is moved away from the top of the receiving cup, making it easy to remove the receiving cup. The receiving cup includes a separator 15. After the material is weighed, the separator 15 is inserted into the cup body 14 from top to bottom, which can divide the material in the cup body 14 into several equal parts, avoiding multiple weighings.

[0021] In order to make the screw jack 12 more stable when driving the electronic scale 13 to rise and fall, a telescopic column 16 is connected between the table 11 and the electronic scale 13 to enhance the stability of the electronic scale 13. The telescopic column 16 includes a column body 161 and a column 162 that is slidably connected to the column body 161.

[0022] To prevent the cup 14 from shaking when the separator 15 is inserted into it, a second bracket 18 is fixedly connected above the table 11. A second collar 182 is fixedly connected to the middle of the second bracket 18. The second collar 182 is positioned directly above the first collar 171. The second collar 182 and the first collar 171 together fit over the receiving cup. Since the platform of the electronic scale 13 is movable, the receiving cup is prone to shaking when the first collar 171 lifts it. After the material is weighed, the screw jack 12 drives the electronic scale 13 to descend, and the first collar 171 no longer lifts the receiving cup, but the second collar 182 lifts it instead.

[0023] In order to enable the second ring 182 to support the receiving cup after the screw jack 12 drives the first ring 171 to descend, the diameter of the second ring 182 is larger than that of the first ring 171, and the outer diameter of the cup body 14 gradually decreases from top to bottom.

[0024] To level the material in the receiving cup, since the uneven distribution of material delivered to the receiving cup by the micro screw feeder 21 results in excessive weight differences in each portion of material when the separator 15 separates the material, this invention also fixes an extension arm 27 to one side of the fixed base 22. A stirring motor 28 is fixedly connected above the extension arm 27. The stirring motor 28 passes through the extension arm 27 and is fixedly connected to stirring teeth 29 for leveling the material in the receiving cup. The stirring motor 28 can drive the stirring teeth 29 to stir the material in the receiving cup. Specifically, the process of leveling the material is as follows: the drive motor 26 drives the stirring teeth 29 to move above the receiving cup, then the electric push rod 23 drives the stirring teeth 29 to descend and enter the receiving cup, and then the stirring motor 28 drives the stirring teeth 29 to stir and turn the surface of the material, so that the surface material is evenly distributed, thereby enabling the separator 15 to distribute the material evenly.

[0025] To ensure that the separator 15 can evenly distribute the material, the separator includes a lid 151 with a notch 1511. Several baffles 152 are rotatably connected to the bottom of the lid 151, and the baffles 152 are evenly distributed in a ring around the center of the lid 151. Use of the separator 15: Insert the separator 15 into the cup body 14. The baffles 152 will evenly divide the material into several portions. Simultaneously, the lid 151 can rotate, allowing the separated material to be poured out through the notch 1511.

[0026] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
