Description

Technical Field

[0001] This utility model relates to the field of rubber extrusion technology, specifically to a rubber extrusion mechanism for rubber heating pretreatment. Background Technology

[0002] A rubber compound extrusion unit for preheating and heating rubber compounds is a device used to heat and extrude rubber compounds, typically in the processing of materials such as rubber and plastics. This device heats the rubber compound to the required temperature and fluidity, and then extrudes it into the desired shape and size using an extruder.

[0003] Common rubber extrusion mechanisms include an extruder, a barrel, and a heating mechanism. During use, the rubber compound inside the barrel is heated and stirred to maintain its good fluidity before being discharged into the extruder for extrusion.

[0004] However, this method involves rotating the mixing blades circumferentially with a motor during mixing, which cannot create complex flow patterns in the rubber compound. This makes it difficult to mix different components of the rubber compound more quickly and evenly. Furthermore, the single mixing method reduces the speed of heat conduction, which can easily lead to local overheating or undercooling. This reduces the heat pretreatment and extrusion quality of the rubber compound and cannot meet the working requirements of rubber compound extrusion. Therefore, a rubber compound extrusion mechanism for heat pretreatment of rubber compound is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a rubber extrusion mechanism for rubber pretreatment heating, which solves the technical problem that simple stirring cannot generate complex flow patterns in the rubber, making it difficult to mix rubbers of different components more quickly and evenly.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rubber extrusion mechanism for rubber compound heating pretreatment, comprising:

[0009] A base, on top of which an extruder is mounted, and on top of which a heating cylinder is mounted via a bracket, and on top of which a mounting bracket is connected to the back of the extruder;

[0010] A pipe clamp bracket is connected to the upper and lower sides of the mounting bracket. A first motor is inserted inside the pipe clamp bracket. A turntable is coaxially connected to the outer end of the rotor of the first motor. A swing arm is connected to the front of the turntable through a bearing.

[0011] A paddle is installed on the lower outer side of the swing arm. A snap-fit ​​frame is fitted on the upper outer side of the swing arm. A top plate is connected to the top of the swing arm. A second motor is installed on the lower surface of the top plate. The rotor of the second motor is coaxially connected to a stirring shaft. A stirring blade is coaxially connected to the bottom end of the stirring shaft.

[0012] Preferably, the number of the paddles is 2-4 sets, the number of the stirring blades is 3-6 sets, and the length of the stirring shaft is greater than the length of the swing arm, so as to avoid interference between the stirring blades and the swing arm.

[0013] Preferably, an assembly cylinder is installed on the top of the mounting frame, and ball bearings are inserted into both sides of the inside of the assembly cylinder. A rotating shaft is inserted into the inner ring of each ball bearing, and the front end of the rotating shaft is connected to the corresponding position on the back of the snap-fit ​​frame, which facilitates transmission.

[0014] Preferably, the mounting frame is a solid steel structure, and reinforcing brackets are welded to both outer sides of the mounting frame. The bottom of the reinforcing brackets is connected to the top of the base at the corresponding position, which enhances the strength and stability of the mounting frame.

[0015] Preferably, the outer side of the rotating shaft is welded to the inner ring of the ball bearing, and the outer ring of the ball bearing is welded to the inner wall of the assembly cylinder, which improves the stability of the rotating shaft rotation, and the length of the rotating shaft is greater than the length of the assembly cylinder.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a rubber extrusion mechanism for rubber pretreatment by heating, which has the following advantages:

[0018] This rubber extrusion mechanism for preheating and heating rubber compounds uses a first motor to drive a turntable, which, in conjunction with a snap-fit ​​frame, causes a swing arm to oscillate left and right. Simultaneously, a second motor drives the rotation of the stirring shaft and stirring blades. This, along with the stirring blades and paddles, rotates and stirs the rubber compound inside the heating cylinder, creating a complex flow pattern within the compound. This promotes faster and more uniform mixing of different components. Furthermore, this complex flow pattern breaks down the internal layered structure of the compound, ensuring sufficient contact between various additives and the compound matrix, thereby improving mixing uniformity and efficiency. The stirring and paddle motion also creates stronger convection, enhancing heat transfer. This convection allows heat to be transferred more rapidly to all parts of the compound, reducing localized overheating or undercooling, thus improving the quality of the preheating and heating process and enhancing the overall quality of the preheating and extrusion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: a rubber extrusion mechanism for rubber pretreatment heating, comprising a base 1, an extruder 2, a heating cylinder 3, a mounting frame 4, a pipe clamp bracket 5, a first motor 6, a turntable 7, an assembly cylinder 8, a swing arm 9, a paddle 10, a ball bearing 11, a rotating shaft 12, a clamping frame 13, a top plate 14, a second motor 15, a stirring shaft 16, stirring blades 17, and a reinforcing bracket 18.

[0026] Please see Figure 1 The base 1 has an extruder 2 mounted on its top. A heated feed cylinder 3 is mounted on the top of the extruder 2 via a bracket. (See also...) Figure 2 The top of the base 1 is connected to the mounting bracket 4 at the back of the extruder 2;

[0027] Please see Figure 3 Pipe clamp 5 is connected to the upper and lower side of the mounting frame 4. The first motor 6 is inserted inside the pipe clamp 5. The rotor of the first motor 6 is coaxially connected to the turntable 7. The front part of the turntable 7 is connected to the swing arm 9 through the bearing.

[0028] Paddle 10 is mounted on the lower outer side of the swing arm 9. Please refer to [link / reference]. Figure 4A snap-fit ​​frame 13 is fitted onto the upper outer side of the swing arm 9. A top plate 14 is connected to the top of the swing arm 9. A second motor 15 is mounted on the lower surface of the top plate 14. The rotor of the second motor 15 is coaxially connected to a stirring shaft 16. Please refer to [link / reference]. Figure 3 and Figure 4 The bottom end of the stirring shaft 16 is coaxially connected to stirring blades 17. There are 2-4 sets of paddles 10 and 3-6 sets of stirring blades 17. The length of the stirring shaft 16 is greater than the length of the swing arm 9. An assembly cylinder 8 is installed on the top of the mounting frame 4. Ball bearings 11 are inserted into both sides of the assembly cylinder 8. A rotating shaft 12 is inserted into the inner ring of each ball bearing 11, and the front end of the rotating shaft 12 is connected to the corresponding position on the back of the snap-fit ​​frame 13. The first motor 6 drives the turntable 7 to rotate, and with the cooperation of the snap-fit ​​frame 13, the swing arm 9 swings back and forth. Simultaneously, the second motor 15 drives the rotation of the stirring shaft 16 and stirring blades 17. Thus, the paddles 10 and stirring blades 17 rotate and stir the rubber material inside the heated material cylinder 3 while simultaneously paddle left and right, thereby creating a complex flow pattern in the rubber material and promoting the mixing of different components. The mixture is mixed quickly and more evenly, and this complex flow pattern can break the layered structure inside the rubber compound, ensuring that various additives and the rubber matrix can fully contact each other, thereby improving the uniformity and efficiency of mixing. Furthermore, the stirring and agitation can create stronger convection in the rubber compound, thereby enhancing the heat transfer effect. This convection can transfer heat to all parts of the rubber compound more quickly, reducing local overheating or undercooling, which helps to improve the quality of the rubber compound's heat pretreatment and improves the quality of the rubber compound's pretreatment and extrusion. The mounting frame 4 is a solid steel structure, and reinforcing brackets 18 are welded to both sides of the outer side of the mounting frame 4. The bottom of the reinforcing brackets 18 is connected to the corresponding position of the top of the base 1. The outer side of the rotating shaft 12 is welded to the inner ring of the ball bearing 11, and the outer ring of the ball bearing 11 is welded to the inner wall of the assembly cylinder 8. The length of the rotating shaft 12 is greater than the length of the assembly cylinder 8.

[0029] This design uses a first motor 6 to drive the rotation of the turntable 7, which, in conjunction with the snap-fit ​​frame 13, causes the swing arm 9 to oscillate left and right. Simultaneously, a second motor 15 drives the rotation of the stirring shaft 16 and the stirring blades 17. This allows the rubber compound inside the heating cylinder 3 to be rotated, stirred, and moved left and right by the paddle 10 and the stirring blades 17, thereby creating a complex flow pattern in the rubber compound. This promotes faster and more uniform mixing of different components of the rubber compound. This complex flow pattern can break down the layered structure inside the rubber compound, ensuring that various additives and the rubber matrix can fully contact each other, thus improving the uniformity and efficiency of mixing. Furthermore, the stirring and moving motion can create stronger convection in the rubber compound, thereby enhancing the heat transfer effect. This convection can transfer heat to all parts of the rubber compound more quickly, reducing local overheating or undercooling, which helps to improve the quality of the rubber compound's heating pretreatment and enhances the quality of the pretreatment and extrusion of the rubber compound.
