Description

Technical Field

[0001] The utility model relates to a material pressing device used on a roller of an open mixing mill, belonging to the field of open mixing mills. Background Art

[0002] An open rubber mixer has two horizontally arranged rollers. It is a machine that mixes rubber (plastic) between the two rollers. It is referred to as an open mixer. It is mainly composed of rollers, a frame, a spacing device and a transmission device. The material is pulled into the gap between the two rollers rotating in opposite directions at different linear speeds under the action of friction. The material in the frame is subjected to strong shearing and extrusion through the gap between the rollers, which increases the material temperature and plasticity, thereby achieving the purpose of mixing rubber. It is used for operations such as plasticating, mixing, tableting and hot mixing.

[0003] In the existing pressing device of the mixing mill, the function of the pressing mechanism is relatively simple, and usually can only realize simple pressing operations, which cannot meet diverse processing needs. For example, for materials that need to be cut or trimmed, traditional pressing devices often require additional equipment or complicated operating procedures, which not only increases production costs, but also reduces production efficiency. In addition, most pressing devices adopt vertical extrusion, which has certain limitations when processing materials of different thicknesses and characteristics. Vertical extrusion cannot adjust the pressing angle according to the specific characteristics of the material, resulting in unsatisfactory pressing effect, especially when processing thicker or harder materials, which is prone to unsolid or uneven pressing. In addition, in terms of the power system, common pressing devices mostly adopt a dual-power structure. Although this design can provide sufficient pressing force, it has a complex structure and high cost, and is prone to mechanical failures in long-term operation, affecting the reliability and production efficiency of the equipment.

[0038] The pressing mechanism 4 is located below the bracket 1 and is connected to the reciprocating output end of the guide rod 2 and the pressing drive device 3 through a fixed block 101. The power frame provides power to the pressing mechanism 4 for extruding the material or performing an inclined downward pressing operation.

[0039] In order to ensure the stability of the structure, the first fixing block 1011 and the second fixing block 1012 are uniformly spaced and symmetrically distributed on the bracket 1, so as to ensure that the guide rod 2 and the pressing drive device 3 maintain stability and symmetry during installation and operation.

[0040] In order to achieve precise alignment, a circular through hole of the same size is provided at the center position of the fixed block 101, and the radius of the circular through hole is consistent with the output end radius of the reciprocating motion of the guide rod 2 and the pressure driving device 3, which is used to ensure that the guide rod 2 and the pressure driving device 3 always remain precisely aligned during the movement.

[0043] In order to meet the pressing requirements of different materials, the pressing mechanism 4 is a pressing roller without a blade, and the pressing roller without a blade is an integral one-piece design.

[0044] In order to ensure the firmness of the blade, the blade is fixed to the press roller by bolts or welding to ensure its stability and firmness during the processing.

[0045] In order to increase the structural strength and stability of the bracket, the bracket 1 includes two supporting legs 102 extending vertically upward and a supporting panel 103 supported by the supporting legs 102. The supporting legs 102 are fixed on the pressure cover of the mixing mill. The supporting legs 102 are respectively connected to the two ends of the supporting panel 103.

During this process, the material pressing mechanism 4 can be selected with or without a blade as needed, which is used to cut and crush the material during the material pressing process to improve processing efficiency and quality.

[0049] The present application provides two different types of pressing rollers for extruding materials, which are suitable for different pressing needs. One pressing roller is equipped with a blade, which can be used for cutting materials; the other is without a blade, which is suitable for simple pressing operations. This design can flexibly cope with a variety of processing scenarios and meet diverse production needs.

In addition, the consistent circular through hole design also facilitates installation and maintenance, reducing production costs and maintenance difficulties.

[0052] The material of the nip roller in the present application can be one of metal materials, composite materials or engineering plastics.

[0053] The extrusion method of the present application is inclined extrusion, which is combined with the inclined connection angle design between the support legs 102 and the support panel 103 on the pressing drive equipment frame 1, and can provide pressing power at different angles when pressing materials.

[0054] Embodiment 1, as Figure 1 and Figure 2 As shown;

[0055] The pressing mechanism 4 is a pressing roller with blades, and the blades thereon are distributed at intervals on the surface of the pressing roller. This design can not only press the material, but also be used to cut the material during the pressing process, which is convenient for subsequent processing and treatment, and the blades thereon are fixed to the pressing roller by bolts or welding or a combination of them. The blade distribution can be uniformly distributed with consistent intervals, or unevenly distributed inside and outside. For example, depending on the characteristics of the material, the blades on the pressing roller can be densely distributed on both sides and spaced in the middle, or densely distributed in the middle and spaced on both sides, or randomly distributed.

[0056] Embodiment 2, as Figure 3 and Figure 4 As shown;

[0057] The pressing mechanism 4 is a pressing roller without a blade. The pressing roller is an integrally formed design, and the surface is carefully processed to have a smooth outer cylindrical surface. This design is mainly used for ordinary pressing of materials and is suitable for occasions where cutting is not required, such as simple flattening or compacting operations.

[0058] Figure 5 This is a structural diagram of Example 1 of the support foot 102 of the present application, that is, when the support plate 1024 is disposed outside the support foot 102, Figure 6 In the embodiment 2 of the supporting foot 102 of the present application, Figure 5 Further optimization is performed on the basis of, that is, support plates 1024 can be provided on the inner and outer sides of the support legs 102 of the present application at the same time to achieve enhanced support for the inner and outer sides of the connecting plate 1022.

[0059] The support plate 1024 in the support foot 102 of the present application can be arranged on the outside of the support foot 102 or on the inside of the support foot 102.

[0060] like Figure 7 As shown, the pressing device of the present application can be installed on an open mixing mill A. The pressing device is fixed on the pressure cover of the open mixing mill A. The length of the pressing mechanism 4 is consistent with the length of the material trough, which can ensure that the pressing mechanism 4 can fully extrude or cut the material. The output end of the material trough is located directly above the roller A1.

[0061] The main function of the guide rod 2 in the present application is to guide or control the movement direction and trajectory of the pressing mechanism 4. The guide rod 2 can reduce the friction and vibration of the mechanical parts during the movement, and improve the accuracy and stability of the movement. In addition, the guide rod 2 also has the task of supporting the piston and transmitting force, so that the gas / oil / hydraulic cylinder can stably withstand various workloads.

[0062] In the present application, a material pressing driving device 3 is used to provide the power required for material extrusion. The material pressing driving device 3 is specifically one of an air cylinder, an oil cylinder, and a hydraulic cylinder. The single air / oil / hydraulic cylinder design reduces the number of mechanical parts, reduces the complexity and cost of the equipment, reduces the downtime caused by mechanical failure, and improves the operating efficiency of the equipment.

[0063] The extrusion direction of the pressing mechanism 4 of the present application is vertical extrusion relative to the supporting panel 103, the supporting panel 103 and the upper top plate 1023 of the top end surface of the supporting foot 102 are fixedly connected, and the upper top plate 1023 is inclined relative to the horizontal plane. Therefore, the pressing mechanism 4 of the present application is to extrude the material at an inclined position, and the guide rod 2 and the pressing drive device 3 jointly ensure the stable operation and precise pressing of the pressing mechanism 4.

[0064] The inclination angle of the upper top plate 1023 in the present application allows the user to adjust the pressing angle during the assembly stage according to specific processing requirements. The range of the inclination angle is 15-45 degrees. This design provides additional flexibility, allowing the device to adapt to materials of different thicknesses and characteristics. By adjusting the connection angle between the support foot 102 and the support panel 103, the user can accurately control the direction in which the pressing drive device 3 applies force to the pressing mechanism 4, thereby optimizing the pressing effect. In addition, the inclination angle adjustment function of the bracket 1 can also help compensate for deviations caused by machine wear or setting errors, thereby ensuring the consistency and accuracy of the pressing process. This adjustable inclination angle provides the operator with a larger operating space, allowing the pressing device to more accurately adapt to specific process requirements and improve production efficiency and product quality.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
