[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0019] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0020] Please see Figures 1 to 6 An automated feeding device for a rubber mixing mill, in this embodiment including: The rubber mixing mill uses an open mill 1. The open mill 1 is equipped with a mounting frame 2. The inner bottom wall of the mounting frame 2 is equipped with a conveyor 3. The mixing mill is divided into an open mill 1 and an internal mixer. When the open mill 1 is used to process rubber, two extrusion rollers are often used to extrude and mix the rubber. At the same time, the extrusion rollers can heat the rubber to soften it, allowing the rubber to be conveyed along the surface of one of the extrusion rollers, thus achieving continuous mixing of the rubber. The open mill 1 is an existing piece of equipment and will not be described in detail. The automatic feeding component 4 for rubber mixing mill: After the existing open mill 1 has finished mixing the rubber, it is often necessary for workers to manually cut and pull the rubber to transport it to the next processing step, such as cooling and cutting the rubber. This increases the labor intensity of workers and reduces the ease of use of the equipment. Thanks to the design of the feeding component 4, the rubber after mixing can be cut and fed, reducing the labor intensity of workers and improving the ease of use of the equipment. The feeding component 4 includes a moving frame 5 and a linear motor 16. The inner side wall of the moving frame 5 is rotatably connected to a threaded rod 6. The threaded rod 6 is threadedly connected to a threaded plate 7. The top surface of the threaded plate 7 is welded with a feeding rack 8.

[0021] The inner wall of the feeding rack 8 is equipped with a feeding cutter disc 9 for automatic rubber feeding. During the movement of the feeding cutter disc 9, it cuts the rubber. At the same time, during the process of the extrusion roller of the open mill 1 conveying the rubber, the feeding cutter disc 9 scrapes the rubber, causing the rubber to detach from the extrusion roller, thus realizing the automatic feeding of the rubber. The rubber falls to the upper part of the conveyor 3 for conveying, so that the rubber is conveyed to the designated position for cooling and cutting, reducing the labor intensity of workers and improving the ease of use of the device. Fixed plates 11 are welded on both sides of the moving frame 5. The bottom surface of the fixed plate 11 is connected to the moving end of the electric push rod 12. The moving part of the linear motor 16 is connected to the positioning frame 13. Two sliding sleeves 14 are welded to the inner bottom wall of the positioning frame 13. Sliding plates 15 are slidably connected to the inner side wall of the sliding sleeves 14. The top surface of the two sliding plates 15 is welded to the mounting frame 2. The fixed ends of the two electric push rods 12 are connected to the positioning frame 13 by bolts.

[0022] The bottom surface of the threaded plate 7 is slidably connected to the movable frame 5. The fixed end of the linear motor 16 is connected to the mounting frame 2 by bolts. The end face of the threaded rod 6 is connected to the output shaft of the rotary motor 10 by a coupling. The fixed end of the rotary motor 10 is connected to the movable frame 5 by bolts. The side of the feeding assembly 4 is provided with a cutting assembly 17. After the rubber compounding is completed, before the rubber is cut by the feeding assembly 4, the rubber needs to be cut by the cutting assembly 17 to cut the rubber to the specified size, so that the rubber is cut to the specified size, thus providing conditions for the automatic feeding of the rubber. The cutting assembly 17 includes a U-shaped connecting frame 18 and a movable frame 20. An electric push rod 19 is installed on the inner bottom wall of the connecting frame 18. The fixed end of the electric push rod 19 is connected to the connecting frame 18 by bolts.

[0023] The moving end of the electric push rod 19 is connected to the movable frame 20. The inner wall of the connecting frame 18 is slidably connected to the movable frame 20. The bottom surface of the connecting frame 18 is welded to the mounting frame 2. The inner wall of the movable frame 20 is welded with a movable rod 21. Two cutting frames 22 are slidably connected to the side of the movable rod 21. The inner wall of the cutting frame 22 is rotatably connected with a cutting disc 23. The side of the cutting frame 22 is threaded with a clamping bolt for tightly abutting the movable rod 21. The inner cavity of the connecting frame 18 has sufficient space to prevent the movable frame 20 from detaching from the connecting frame 18 during vertical movement. The mounting frame 2 and the conveyor 3 are installed and fixed below the extrusion roller of the open mill 1 to provide conditions for rubber cutting and automatic feeding. The lower part of the mounting frame 2 can be equipped with an electric push rod according to the usage requirements, which provides convenience for moving the mounting frame 2 to a designated position for use.

[0024] To perform cutting, the electric push rod 29 provides power, causing the movable frame 20 to move down the path of the connecting frame 18. With the connection of the movable rod 21 and the cutting frame 22, the two cutting discs 23 are moved to a specified height to cut the rubber. At the same time, the two cutting frames 22 can move down the path of the movable rod 21 to adjust the position of the two cutting discs 23 to suit the cutting size requirements of the rubber.

[0025] For automatic feeding, a linear motor 16 provides power, causing the positioning frame 13 to drive the two sliding sleeves 14 to move along the path of the slide plate 15. At the same time, two electric push rods 12 provide power, causing the feeding cutter head 9 to move to a designated height during the transmission process. A rotary motor 10 provides power, causing the threaded plate 7 to move along the threaded path of the threaded rod 6, so that the feeding cutter head 9 cuts the rubber after the mixing process. At the same time, during the process of the extrusion rollers of the open mill 1 conveying the rubber, the feeding cutter head 9 scrapes the rubber, causing the rubber to fall off the surface of the automatic extrusion rollers and onto the surface of the conveyor belt of the conveyor 3. This realizes the automatic feeding and conveying of rubber by the device, reducing the labor intensity of workers and improving the ease of use of the device.

[0026] The open mill 1, conveyor 3, rotary motor 10, electric push rod 12, linear motor 16, and electric push rod 2 19 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0027] Working principle The rubber mixing machine uses an automated feeding device. When automatic feeding is required, the electric push rod 19 is activated, causing the movable frame 20 to move along the path of the connecting frame 18. During the transmission process, the two cutting discs 23 cut the rubber. The linear motor 16, rotary motor 10, and two electric push rods 12 are started. The positioning frame 13 drives the two sliding sleeves 14 to move along the path of the slide plate 15. The threaded plate 7 moves down along the threaded path of the threaded rod 6, so that the feeding cutter 9 moves to the designated position to cut the rubber. At the same time, the feeding cutter 9 scrapes the rubber, so that the rubber gets off the extrusion roller of the mill 1 and falls onto the surface of the conveyor belt of the conveyor 3, thus realizing the automatic feeding and conveying of the rubber. The two cutting racks 22 can move along the path of the movable rod 21, and the distance between the two cutting blades 23 can be adjusted during the transmission process to adapt to the cutting size requirements of rubber.
