Description

Technical Field

[0001] This utility model relates to the field of open mill technology, specifically to an automatic rubber-turning device for an open mill. Background Technology

[0002] In the rubber refining process, the open mill mainly relies on two relatively rotating rollers to squeeze and shear the rubber compound. Through multiple kneading processes and the accompanying chemical reactions, the large molecular chains inside the rubber are broken, so that the various components in the formula are mixed evenly, and finally the purpose of rubber refining is achieved.

[0003] Currently, when the open mill extrudes rubber compound, rubber particles or lumps may adhere to the extrusion rollers. When the extrusion rollers with these particles or lumps extrude the rubber compound, through holes or grooves may appear on the extruded rubber compound, which will affect the quality of the final molded rubber compound.

[0004] Therefore, we propose an automatic rubber-turning device for open mills to solve the above problems. Utility Model Content

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.

[0027] Example

[0028] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides an automatic rubber turning device for an open mill, including a base plate 1. First fixing plates 2 are fixedly arranged on both sides of the upper end face of the base plate 1. Two extrusion rollers 3 are rotatably arranged between the two first fixing plates 2. A second fixing plate 4 is fixedly arranged on the upper end face of the first fixing plates 2. A first guide roller 5 and a second guide roller 6 are arranged between the two second fixing plates 4. Two automatic rubber turning rods 7 are arranged below the first guide rollers 5. A connecting plate 8 is arranged above the two extrusion rollers 3. The two ends of the connecting plate 8 are fixedly connected to the two second fixing plates 4.

[0029] The connecting plate 8 has an insertion port 9 on the side wall opposite to the extrusion roller 3. Multiple extrusion springs 10 are fixedly fixed to the bottom of the inner side of the insertion port 9. Insert plates 11 are inserted into each insertion port 9. One end of the extrusion spring 10 in the insertion port 9 is fixedly connected to the insert plate 11 inserted in the insertion port 9. A cleaning scraper 12 is fixedly installed at the end of the insert plate 11 away from the connecting plate 8. Two cleaning scrapers 12 are respectively mounted on the two extrusion rollers 3. A sliding plate 13 is fixedly installed on the side wall opposite to the two connecting plates 8. The cross-section of the sliding plate 13 is a right-angled triangle.

[0030] The connecting plate 8 and the cleaning scraper 12 can scrape off the glue particles or blocks attached to the extrusion roller 3, thus preventing the glue particles or blocks attached to the extrusion roller 3 from causing through holes or grooves in the extruded material when it is extruded, which would affect the final molding quality of the material. The insertion port 9, the insertion plate 11, and the extrusion spring 10 can retract the cleaning scraper 12 into the insertion port 9, thus preventing the cleaning scraper 12 from being damaged by the glue particles or blocks that are firmly attached to the extrusion roller 3. By repeatedly scraping off and loosening the glue particles or blocks that are firmly attached to the extrusion roller 3, the glue particles or blocks on the extrusion roller 3 can be scraped off, thus protecting the cleaning scraper 12. In addition, the slide plate 13 guides the material being fed between the two extrusion rollers 3.

[0031] The first guide roller 5 has first mounting seats 14 at both ends, which are fixedly connected to the second fixing plate 4. The second guide roller 6 is located above the first guide roller 5, and third fixing plates 15 are rotatably mounted at both ends of the second guide roller 6. Second mounting seats 16 are rotatably mounted on both third fixing plates 15, and are fixedly connected to the second fixing plate 4. The first mounting seats 14 are used to fix the first guide roller 5 and the second fixing plate 4 together, and the third fixing plates 15 and the second mounting seats 16 are used to fix the first guide roller 5 and the second fixing plate 4 together.

[0032] A support frame 17 is fixedly mounted on one of the second fixed plates 4. Two support frames 17 are provided, and a servo motor 18 is fixedly mounted on each of the two support frames 17. The output ends of the two servo motors 18 are respectively connected to the first guide roller 5 and a third fixed plate 15. The servo motor 18 connected to the first guide roller 5 provides kinetic energy for the rotation of the first guide roller 5, and the servo motor 18 connected to the third fixed plate 15 can drive the second guide roller 6 to rotate, thereby adjusting the distance between the first guide roller 5 and the second guide roller 6.

[0033] The automatic glue-turning rod 7 is fixedly mounted on the moving plate 19. A rodless cylinder 20 is fixedly mounted between the two second fixed plates 4, and the moving plate 19 is mounted on the rodless cylinder 20. Sensing rods 21 are fixedly mounted at both ends of the moving plate 19, and an anti-collision head 22 is fixedly mounted at the end of the sensing rod 21 furthest from the moving plate 19. The rodless cylinder 20 is used to drive the automatic glue-turning rod 7 to move horizontally left and right. The sensing rods 21 are used to detect the left and right movement distance of the automatic glue-turning rod 7. The anti-collision head 22 prevents the sensing rods 21 from directly impacting the second fixed plates 4 and causing damage to the sensing rods 21.

[0034] Guide rods 23 are provided below the two automatic glue-turning rods 7. Third mounting seats 24 are rotatably mounted at both ends of the guide rods 23, and the third mounting seats 24 are fixedly connected to the second fixed plate 4. The guide rods 23 are designed to rotate the glue material when it is fed to the first guide roller 5.

[0035] A fixed crossbar 25 is fixedly disposed between the two first fixed plates 2. Two limiting plates 26 are fixedly disposed on the fixed crossbar 25. The two limiting plates 26 are located on both sides below an extrusion roller 3. A receiving tray 27 is disposed on the upper end surface of the base plate 1. The fixed crossbar 25 and the limiting plates 26 are used to limit the width of the rubber material being extruded on the extrusion roller 3. The receiving tray 27 is used to receive the scraps of rubber material that fall off during processing.

[0036] The working principle of this practical application is as follows:

[0037] First, the two extrusion rollers 3 and the servo motor 18 connected to one end of the first guide roller 5 are started. Then, rubber material is added between the two extrusion rollers 3. The rubber material added between the two extrusion rollers 3 is extruded into a sheet. Then, the extruded rubber sheet is placed on the guide rod 23, passed between the two automatic rubber-turning rods 7, and placed on the first guide roller 5. At this time, the servo motor 18 connected to the third fixed plate 15 is started. The start of the servo motor 18 drives the second guide roller 6 to rotate through the third fixed plate 15 until the second guide roller 6 extrudes the rubber material placed on the first guide roller 5. The rotation of the first guide roller 5... The movement will convey the rubber material placed on it to one side of the first guide roller 5. During the conveying of the rubber material, the first guide roller 5 activates the rodless cylinder 20. The activation of the rodless cylinder 20 drives the automatic rubber-turning rod 7 to move back and forth in the horizontal direction through the moving plate 19. The movement of the automatic rubber-turning rod 7 turns the squeezed rubber sheet, thereby folding the two sides of the rubber sheet towards the middle. After being turned, the rubber material will pass through the gap between the first guide roller 5 and the second guide roller 6. The rubber material passing through the gap between the first guide roller 5 and the second guide roller 6 is squeezed and falls between the two connecting plates 8. The adhesive material between the connecting plates 8 slides under the guide of the slide plate 13 between the two extrusion rollers 3 for further extrusion, forming a closed loop. This process of extrusion, turning, and extrusion is repeated multiple times until the adhesive material reaches the specified standard, at which point it can be removed from the device. If adhesive particles or lumps adhere to the extrusion rollers 3 during extrusion, these particles or lumps will be transferred to the cleaning scraper 12 mounted on top of the extrusion rollers 3. The cleaning scraper 12 will scrape off the adhesive particles or lumps. If the adhesion of the adhesive particles or lumps is strong, the cleaning scraper 12 will be forced through the insert plate 11 into the insertion port 9. As the bottom side moves, the movement of the insert plate 11 presses against the compression spring 10 inside the insertion port 9. The compression spring 10 contracts under force. When the cleaning scraper 12 is misaligned with the rubber particles or blocks on the compression wheel 3, the cleaning scraper 12 returns to its original position on the compression wheel 3 under the elastic characteristics of the compression spring 10. When the rubber particles or blocks with a large adhesion on the compression wheel 3 pass by the cleaning scraper 12 again, the cleaning scraper 12 contracts again. This process is repeated multiple times to scrape off the rubber particles or blocks attached to the compression wheel 3. The repeated scraping loosens the rubber particles or blocks attached to the compression wheel 3, and finally, the rubber particles or blocks on the compression wheel 3 are scraped off.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
