Description

Technical Field

[0001] The present invention relates to the technical field of rubber roller production, in particular to a rubber pressing device for rubber roller production. Background Art

[0002] In the rubber roller production process, rubber pressing is a critical step, its purpose being to plasticize, heat-refine, and mix the rubber to improve its quality. Traditional rubber mixing mills have a low level of automation. During the rubber pressing process, operators are required to frequently reel and flip the rubber to change its direction, ensuring more even rolling and improving the mixing effect. However, this method requires extremely high operator proficiency, which not only increases the operator's workload but also easily leads to uneven rubber pressing due to improper operation, affecting the quality of the rubber roller. Furthermore, traditional rubber mixing mills are difficult to flexibly adjust to the characteristics of different rubber compounds and production needs, making them unable to meet the requirements of diversified rubber roller production. For example, patent application CN202310912932.2 provides a mixing and laminating device for textile rubber roller production. The device comprises a base plate, two support frames, two crossbeams fixed to the upper ends of the two support frames, two pressure rollers rotatably disposed between the crossbeams, a mixing mechanism provided at the side ends of the pressure rollers, a translation mechanism provided on the plate, and an auxiliary roller rotatably disposed at one end of the conveyor, with a guide mechanism provided at the upper end. The device circulates rubber and staggers and folds the rubber during the circulation process, improving automation and rubber refining efficiency. The cyclically pressed rubber is evenly distributed between the two pressure rollers, further improving the uniformity of the rubber pressure and the rubber refining efficiency. However, since the rubber layer thickness of the rubber rollers varies, the fixed spacing between the pressure rollers results in a single thickness of the extruded rubber sheet, making it difficult to meet the base rubber thickness requirements of different rubber roller products, limiting the versatility of the device. Furthermore, different pressing gaps are required for rubber materials of different hardness and viscosity during the laminating process. For example, high-viscosity rubber requires a smaller gap to ensure adequate compaction, while low-viscosity rubber requires a larger gap to prevent excessive stretching. Fixed spacing will lead to insufficient or excessive pressing of some materials, reducing the uniformity of rubber mixing. Therefore, it is necessary to develop a rubber pressing device for rubber roller production to address the above defects. Summary of the Invention

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the three-dimensional structure of a rubber pressing device for producing rubber rollers of the present invention; Figure 2 This is a schematic diagram of the main structure of the glue pressing device for producing rubber rollers of the present invention; Figure 3 This is a left-side structural schematic diagram of a rubber roller production glue pressing device of the present invention; Figure 4 This is a schematic structural diagram of the sliding assembly and the driving assembly of the present invention; Figure 5 Schematic diagram of the swing assembly of the present invention.

[0029] In one embodiment, Figures 1 to 5 As shown, a rubber pressing device for rubber roller production includes a base plate 1 and two support frames 2 vertically fixed to the base plate 1. The support frames 2 are welded to the ends of the base plate 1. The upper ends of the two support frames 2 are machined with bearing seats for mounting the fixed pressure roller 3 and slide grooves 603 for the movable pressure roller 4. The bearing seats and slide grooves 603 are symmetrically arranged.

[0030] In one embodiment, Figures 1 to 5 As shown, a fixed pressure roller 3 and a movable pressure roller 4 are provided in parallel at the upper ends of the two support frames 2. The two ends of the fixed pressure roller 3 are rotatably mounted on the bearing seats of the support frames 2 through deep groove ball bearings, and the two ends of the movable pressure roller 4 are mounted in the sliding seat 601 through bearings to ensure flexible rotation. The sliding assembly 6 drives the movable pressure roller 4 to move closer to or away from the fixed pressure roller 3. The slide groove 603 is opened on the outside of the support frame 2 and adopts a clearance fit with the sliding seat 601 to ensure smooth sliding without jamming. The first electric telescopic rod 602 is horizontally arranged on the outside of the support frame 2. The protruding end of the first electric telescopic rod 602 passes through the support frame 2 and is fixed on the sliding seat 601. The first electric telescopic rod 602 drives the sliding seat 601 to move closer to or away from the fixed pressure roller 3.

[0031] To prevent guide distortion when pushing the sliding seat 601, the first electric telescopic rods 602 are of the same model. Encoders are installed on each of the two first electric telescopic rods 602 to output real-time position signals. These encoders are then controlled by a control system to achieve synchronization. This structure is conventional and commonly used in actual production, so it will not be further explained here. The synchronization control method for the second electric telescopic rod 901 and the third electric telescopic rod 1204 is the same as that for the first electric telescopic rod 602, both achieved through encoders and a control system.

[0032] A pressure sensor is provided on one side of the sliding seat 601. One end of the pressure sensor is fixed to the side of the sliding seat 601, and the front end abuts against the outer side surfaces of the bearing seats at both ends of the fixed pressure roller 3. It is used to detect the pressing pressure between the movable pressure roller 4 and the fixed pressure roller 3, collect pressure data in real time and feed it back to the control system, and form a pressure closed-loop adjustment with the first electric telescopic rod 602.

[0033] In one embodiment, Figures 1 to 5As shown, one end of the fixed pressure roller 3 and the movable pressure roller 4 extends out of the support frame 2 and is respectively connected to a drive assembly 5. The drive assembly 5 includes a first bevel gear 501, a second bevel gear 502, and a third bevel gear 503, as well as a rotating shaft 504 driven by a first motor 507. The first motor 507 is fixedly mounted on the outer wall of the support frame 2 via a motor mount. The output shaft of the first motor 507 is connected to the fixed shaft section of the rotating shaft 504 via an elastic coupling to ensure smooth power transmission. The first bevel gear 501 is provided in two pieces, fixedly mounted on one end of the fixed pressure roller 3 and the movable pressure roller 4, respectively. The two first bevel gears 501 mesh with the second bevel gear 502 and the third bevel gear 503, respectively.

[0034] The first motor 507 drives the rotating shaft 504 to rotate, causing the second bevel gear 502 and the third bevel gear 503 mounted on the rotating shaft 504 to rotate, thereby causing the two first bevel gears 501 meshing therewith to rotate simultaneously, driving the fixed pressure roller 3 and the movable pressure roller 4 to rotate in opposite directions. The rotating shaft 504 is connected to the third bevel gear 503 via a spline structure 505 to adapt to the position changes of the movable pressure roller 4. The rotating shaft 504 includes a fixed shaft section and a sliding shaft section. The fixed shaft section is fixedly connected to the second bevel gear 502, and the sliding shaft section is slidingly connected to the fixed shaft section via a spline sleeve and rotates synchronously. The spline sleeve is fixed in the sliding shaft section and is adapted to the external spline of the fixed shaft section to ensure that the circumferential transmission is not interrupted during axial sliding. The end of the sliding shaft section is fixedly connected to the third bevel gear 503, and the third bevel gear 503 is rotatably mounted on the connecting plate 506 via a bearing to ensure transmission continuity when the movable pressure roller 4 moves.

[0035] In one embodiment, Figures 1 to 5 As shown, an inclined feed assembly 7 is installed above the fixed and movable rollers 3 and 4. It is fixed to the support frame 2 on one side, with its feed direction perpendicular to the axis of the fixed roller 3, ensuring uniform feed of the rubber material along the length of the gap between the two rollers. A thickness adjustment baffle is installed at the outlet of the feed assembly 7. Both ends of the baffle are connected to the feed assembly 7 frame via waist-shaped holes. By loosening and tightening the hexagon socket bolts in the waist-shaped holes, the gap between the baffle and the feed assembly 7 conveyor belt is adjusted to control the feed thickness, ensuring uniformity and preventing accumulation.

[0036] In one embodiment, Figures 1 to 5As shown, a collecting platform 8 is provided at the lower end of the fixed pressure roller 3 and the movable pressure roller 4, and its length matches that of the fixed pressure roller 3. A guide groove 903 is provided on the support frame 2 corresponding to the collecting platform 8, and guide columns 904 are provided on both sides of the collecting platform 8 to slide in cooperation with the guide groove 903. The guide groove 903 is set at an angle of 45° relative to the horizontal plane to ensure that the collecting platform 8 flips synchronously when sliding. The collecting platform 8 is driven to rotate around the horizontal axis by the flipping assembly 9. The flipping assembly 9 includes a second electric telescopic rod 901 and a crossbeam 902. The lower end of the collecting platform 8 is hinged to the output end of the second electric telescopic rod 901. The rear end of the second electric telescopic rod 901 is rotatably mounted on the crossbeam 902. The crossbeam 902 is horizontally fixed in the middle of the support frame 2. The second electric telescopic rod 901 drives the collecting platform 8 to flip when sliding in the guide groove 903.

[0037] An infrared distance sensor is installed above the collection platform 8 to detect the thickness of the rubber sheets. When the infrared distance sensor detects that the thickness of the rubber sheets reaches 50-80 mm, it sends a signal to the control system, which retracts the second electric telescopic rod 901, causing the collection platform 8 to slide along the guide groove 903 and simultaneously flip.

[0038] In one embodiment, Figures 1 to 5 As shown, a rocking assembly 12 is installed between the discharge side of the fixed roller 3 and the movable roller 4 and the feed end of the collection platform 8. This rocking assembly 12 comprises two rocking arms 1201, two fixed blocks 1202, and two third electrically operated telescopic rods 1204. The two rocking arms 1201 are arranged parallel to the axis of the fixed roller 3, and the distance between them is greater than the minimum spacing between the roller surfaces of the fixed roller 3 and the movable roller 4. This ensures that rubber falling from between the two rollers can fully enter between the two rocking arms 1201, preventing the rubber from getting stuck. Both ends of each swing rod 1201 are mounted on the corresponding fixed block 1202 through bearings. A fixed block groove 1203 is provided on the inner side of the support frame 2 corresponding to the fixed block 1202, and the fixed block 1202 is slidably mounted in the fixed block groove 1203; two third electric telescopic rods 1204 are respectively fixed on the inner side walls of the two support frames 2, and their protruding ends are fixedly connected to the fixed block 1202 on the same side; when the photoelectric sensors on the discharge side of the fixed pressure roller 3 and the movable pressure roller 4 detect that the rubber sheet is falling, the third electric telescopic rod 1204 drives the fixed block 1202 to drive the swing rod 1201 to reciprocate in the fixed block groove 1203, guiding the rubber material to fall evenly into the collection table 8.

[0039] In one embodiment, Figures 1 to 5As shown, a conveyor assembly is installed at the lower end of the collection platform 8 to transfer the rubber material to the loading assembly 7. The conveyor assembly comprises a horizontal conveyor belt 10 and a curved conveyor belt 11. The horizontal conveyor belt 10 is located below the collection platform 8 and receives the rubber material transferred by the turning assembly 9. The curved conveyor belt 11 connects the horizontal conveyor belt 10 to the loading assembly 7. The horizontal conveyor belt 10 and the curved conveyor belt 11 have the same linear speed as the loading assembly 7 to prevent stretching deformation or accumulation and blockage of the rubber material during transportation due to speed differences. A guide and correction device is installed at the junction of the horizontal conveyor belt 10 and the curved conveyor belt 11. The guide and correction device comprises two diffuse reflection photoelectric sensors symmetrically mounted on either side of the horizontal conveyor belt, with a spacing matching the width of the rubber material. Four lateral guide rollers, arranged in pairs, are installed on either side of the junction between the horizontal conveyor belt and the curved conveyor belt. When the photoelectric sensors detect that the rubber material is deflected by more than 5 mm, the control system drives the lateral guide rollers for fine-tuning to ensure that the rubber material enters the loading assembly 7 in a centered manner.

[0040] In one embodiment, Figures 1 to 5 As shown, a displacement sensor is provided between the fixed pressing roller 3 and the movable pressing roller 4. The displacement sensor is electrically connected to the control system. The control system automatically adjusts the operating status of the sliding component 6, the flipping component 9, the rocking component 12 and the driving component 5 based on the preset pressing parameters.

[0041] The rubber pressing device for rubber roller production according to the present invention operates as follows: the rubber raw material to be processed is placed in the loading assembly 7, which directs the rubber between the fixed pressure roller 3 and the movable pressure roller 4. The control system drives the first electric telescopic rod 602 to move the movable pressure roller 4 according to preset parameters. A displacement sensor monitors the distance between the two rollers in real time until the target gap is reached. The first motor 507 is activated, and power is transmitted to the fixed pressure roller 3 and the movable pressure roller 4 via the rotating shaft 504 and the bevel gear set, driving the two rollers to rotate in opposite directions to press the rubber. The pressure sensor provides real-time feedback, and the control system automatically adjusts the speed of the first electric telescopic rod 602 or the first motor 507 to ensure uniform pressure. After pressing, the rubber sheet falls. The photoelectric sensor detects the rubber sheet and activates the swing assembly 12. The third electric telescopic rod 1204 drives the swing arm 1201 back and forth, causing the rubber sheet to fold and fall onto the collection table 8. When the thickness of the rubber sheets accumulated on the collecting table 8 reaches 50 to 80 mm, the turning component 9 drives the collecting table 8 to turn over, and the rubber material is returned to the feeding component 7 via the horizontal conveyor belt 10 and the arc conveyor belt 11, entering the next pressing cycle, achieving multiple uniform refining.
