Description

Technical Field

[0001] This utility model relates to the field of rubber mixing machine technology, and in particular to a feeding device for an open rubber mixing machine. Background Technology

[0002] An open mixing mill is a machine that uses two horizontally arranged rollers to mix rubber (plasticize) between the two rollers. The material is drawn into the gap between the two rotating rollers at different linear velocities under the action of friction. As the material passes through the gap, it undergoes intense shearing and compression, causing its temperature to rise and its plasticity to increase, thus achieving the purpose of rubber mixing. It is used for plasticizing, mixing, sheeting, and hot refining.

[0003] However, traditional feeding methods have many shortcomings. First, relying entirely on manual feeding requires operators to frequently move and throw large amounts of rubber material onto the drums, resulting in extremely high labor intensity and low feeding efficiency, which has become a bottleneck restricting production efficiency. Second, during manual feeding, workers must be in close proximity to the high-temperature and high-speed rotating drums for extended periods, posing serious safety hazards and easily leading to burns or mechanical injuries. Furthermore, while some existing mechanical feeding devices, such as fixed-position conveyor belts or simple feeding machines, alleviate the burden of manual labor to some extent, their positions are usually fixed and cannot be used for lateral material distribution according to the width of the rubber mixing mill drums. This results in uneven accumulation of rubber material on the drums, affecting the quality of the rubber compounding. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a feeding device for an open rubber mixing mill.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a feeding device for an open-type rubber mixing mill, including a fixed base 1. The top of the fixed base 1 is connected to a storage tank 4 for storing rubber materials via a transverse moving component 3. A discharge hopper 5 is located at the bottom of the storage tank 4. A vertically upward supporting frame 6 is provided on the outer wall of the storage tank 4. A vertically upward auger conveyor 7 is fixedly installed inside the supporting frame 6. A horizontal frame 8 is provided at the top of the supporting frame 6. A horizontally arranged horizontal auger conveyor 9 is installed inside the horizontal frame 8. The inlet of the vertical auger conveyor 7 is connected to the outlet of the discharge hopper 5. The outlet of the vertical auger conveyor 7 is inclined. The diagonally downward transfer pipe 10 is connected at its bottom end to the inlet of the horizontal auger conveyor 9. The outlet of the horizontal auger conveyor 9 is provided with a vertically downward discharge pipe 11. The bottom end of the discharge pipe 11 is higher than the top of the drum of the rubber mixing mill. The rubber material falls from the storage box 4 through the discharge hopper 5 into the vertical auger conveyor 7, is vertically lifted to the top, enters the horizontal auger conveyor 9 through the transfer pipe 10, is horizontally conveyed to the discharge pipe 11, and is finally discharged onto the drum of the rubber mixing mill. The lateral movement component 3 allows the storage box 4 to move laterally, thereby adjusting the storage position and preventing the rubber material from falling off the outside of the drum of the rubber mixing mill when discharging from one position.

[0020] The lateral movement component 3 includes support plates 12 vertically upward at both ends of the fixed base 1, multiple guide components 13 located on both sides of the storage box 4 between the two support plates 12, and a drive component 14 for driving the storage box 4 to move horizontally between the two support plates 12. The support plates 12 provide fixed support, the guide components 13 guide the storage box 4 to move in a straight line, and the drive component 14 provides power to make the storage box 4 reciprocate horizontally.

[0021] The guide assembly 13 is provided in two groups, with at least two guide assemblies in each group. The guide assembly 13 includes a guide slide rail 23 located between two support plates 12. The outer wall of the storage box 4 is provided with a guide slider 15 that matches the guide slide rail 23. The guide slider 15 moves along the guide slide rail 23, which improves the stability of the horizontal movement of the storage box 4.

[0022] The drive assembly 14 includes a reciprocating lead screw 16 disposed between two support plates 12 and located below the storage box 4. A servo motor 17 that drives the reciprocating lead screw 16 to rotate is mounted on one of the support plates 12. A sliding block 24 that is threadedly connected to the reciprocating lead screw 16 is provided at the bottom of the storage box 4. The output shaft of the servo motor 17 drives the reciprocating lead screw 16 to rotate, so that the sliding block 24 is threadedly connected to the reciprocating lead screw 16, thereby enabling the sliding block 24 to drive the storage box 4 to move horizontally.

[0023] The bottom of the fixed base 1 is connected to a movable base 19 via a lifting and adjusting assembly 18. Each corner of the movable base 19 is equipped with a foot brake caster 2. The feeding device can be moved by the foot brake caster 2. After moving to the working position, the foot brake caster 2 is locked.

[0024] The lifting and adjusting assembly 18 includes a hydraulic cylinder 20 installed vertically upward in the middle of the movable base 19. The output shaft of the hydraulic cylinder 20 is connected to the middle of the fixed base 1. The output shaft of the hydraulic cylinder 20 drives the fixed base 1 to lift and lower, thereby adjusting the height of the discharge pipe 11.

[0025] The lifting adjustment assembly 18 also includes a guide sleeve 21 that is vertically upward at the corner of the movable base 19. A guide rod 22 that is nested with the guide sleeve 21 is provided at the bottom corner of the fixed base 1. The guide rod 22 slides vertically within the guide sleeve 21, restricting the fixed base 1 to move only vertically, avoiding lateral swaying, and improving the stability of height adjustment.

[0026] During operation, the feeding device is moved to the vicinity of the rubber mixing mill via the foot brake caster 2. The lifting adjustment component 18 is adjusted so that the bottom end of the discharge pipe 11 moves above the rubber mixing mill drum. The servo motor 17 is started, driving the reciprocating screw 16 to rotate and move the storage box 4 laterally. At the same time, the vertical auger conveyor 7 and the horizontal auger conveyor 9 are started. The rubber material enters the vertical auger conveyor 7 from the storage box 4 through the discharge hopper 5. After being lifted, it enters the horizontal auger conveyor 9 through the transfer pipe 10. Finally, it is evenly discharged onto the rubber mixing mill drum through the discharge pipe 11. Through lateral movement, the rubber material can be evenly distributed in the width direction of the drum.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
