Description

Technical Field

[0001] The present invention is a fully automatic open mill, belonging to the field of open mills. Background Art

[0002] The open mill is one of the commonly used devices in the rubber processing industry, usually used in combination with an internal mixer. It can melt and blend many types of materials, including natural rubber, synthetic rubber, PVC, PE, PP, EVA, etc. that are vulcanized and formed by a vulcanizer and injection molded. These materials need to be dispersed and mixed by the internal mixer and the open mill. After being kneaded by the internal mixer according to a specific raw material formula, the original raw materials and compounding ingredients in the form of colloid, particles, and powder are fused and dissolved into rubber masses.

[0003] However, there are many defects in the design of the existing open mills. For example, when the pressing mechanism on the open mill extrudes the material, it usually extrudes the material vertically or only relies on the pressing roller to extrude the material; when processing the extruded rubber compound, it mostly relies on the operator to manually turn the material and repeatedly feed it until the processing is completed, resulting in low work efficiency and low safety of manual operation; there is also some rubber compound remaining on the roller, which will not only increase the production cost but also affect the working efficiency of the equipment in the long run. In summary, the traditional open mill cannot accurately control the precision during the open mill mixing of rubber compounds, wasting manpower and material resources and having low work efficiency. Summary of the Invention

Through the extrusion of the pressure device, the extrusion between the rollers, and the guiding and turning of the manipulator device in sequence, the uniform mixing of the material is finally achieved.

[0006] Further, the pressure device includes a pressure support, a pressure roller, and a pressure cylinder. The top of the pressure support is inclined to the horizontal plane, and the pressure roller and the pressure cylinder are fixedly connected to the inside and outside of the pressure support through a guide rod seat and a fixed block.

[0007] Further, three fixed blocks are arranged at intervals on the top of the pressure support, and guide rod seats are also arranged on the two side fixed blocks. The guide rod is connected to the pressure roller through the guide rod seat.

[0012] Further, the manipulator device includes a manipulator base, a moving device, and a manipulator body. Inside the moving device, a slide rail and a rack are arranged side by side at intervals and are located on the manipulator base.

Detailed implementation manners

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] As Figure 1 , Figure 2 shown, the present invention provides a technical solution for a full-automatic kneader: Two rollers are arranged side by side inside the full-automatic kneader. Among them, the length direction of the rollers of the full-automatic kneader is defined as the left-right direction, and the width direction of the rollers is defined as the front-back direction. It is characterized in that it includes: Frame 1, a frame gland 11 is provided at the upper end of the frame 1, the rollers are fixed inside the frame 1 through roller bearing seats 12, an automatic feeding rack 13 is provided behind the frame 1, and a power device 5 is provided on the right side of the frame 1; Pressure device 2, the pressure device 2 is used to provide an inclined extrusion to the material and is fixedly arranged on the frame gland 11; Scraper device 3, the scraper device 3 is used to remove the residual material on the rollers and is fixedly arranged on the roller bearing seat 12; Manipulator device 4, the manipulator device 4 is used to turn and guide the material in the left-right direction and is fixedly arranged on the frame 1 and is located directly below the rollers of the kneader; Among them, the material is lifted to directly above the kneader through the automatic feeding rack 13, and the material is poured into the kneader. It is successively subjected to the extrusion of the pressure device 2, the extrusion between the rollers, and the guiding and turning of the manipulator device 4, and finally the uniform mixing of the material is realized.

[0021] In order to realize the extrusion of the material, the pressure device 2 includes a pressure support 21, a pressure roller 22 and a pressure cylinder 23. The top of the pressure support 21 is inclined with respect to the horizontal plane, and the pressure roller 22 and the pressure cylinder 23 are fixedly connected and arranged on the inside and outside of the pressure support 21 through a guide rod seat 25 and a fixed block 24.

[0022] To fix the pressure device, three fixing blocks 24 are provided at intervals on the top of the pressure bracket 21, and guide rod seats 25 are also provided on the two side fixing blocks 24. The guide rod 26 is connected to the pressure roller 22 through the guide rod seats 25.

[0023] To cut the material, the pressure roller 22 is one of the types with blades or without blades, and the blades are arranged at intervals or without intervals on the pressure roller 22.

[0024] To clean the material, the scraper device 3 includes a scraper blade holder 31, a blade holder fixing plate 32, an adjusting mechanism 33 and a scraper 34. A scraper 34 parallel to the horizontal plane is provided between the scraper blade holders 31, and a blade holder fixing plate 32 is fixedly provided outside the scraper blade holder 31, and an adjusting mechanism 33 is provided inside the blade holder fixing plate 32.

[0025] To meet the residue of materials at different positions, the adjusting mechanism 33 is one of manual adjustment or electric adjustment, and the adjustment angle is 15 - 70°.

[0026] To adapt to different scenarios, the driving cylinder 331 used for electric adjustment is one of an electric cylinder, a hydraulic cylinder or a pneumatic cylinder. A first adjustment seat 332 and a second adjustment seat 333 are respectively provided at the head and the tail of the driving cylinder 331. The first adjustment seat 332 and the scraper blade holder 31 are detachably connected, and a driving cylinder fixing plate 334 is detachably connected to the outside of the second adjustment seat 333.

[0027] To realize the movement of the manipulator device, the manipulator device 4 includes a manipulator base 41, a moving device 42 and a manipulator body 43. Inside the moving device 42, a slide rail 421 and a rack 422 are arranged side by side at intervals and are located on the manipulator base 41. The manipulator body 43 is slidably arranged on the manipulator base 41 through a slider 431 and a gear 432 fixedly provided at its bottom.

[0028] To realize material guiding, a front - and - rear telescopic motor 433 is provided on the upper end face of the manipulator body 43, and the telescopic movement of the ramming roller 434 inside the manipulator body 43 is realized through the front - and - rear telescopic motor 433. A left - and - right moving motor 435 is provided at the upper end of the manipulator body 43.

[0029] To realize the left - and - right movement of the manipulator body, two slide rails 421 are provided on the moving device 42 and are fitted with the slider 431, and the rack 422 is arranged in the middle of the slide rails 421 and meshes with the gear 432.

[0030] The operator faces the open mill and stands on the side far from the automatic feeding rack 13. Taking the operator's left hand as the left side and the operator's right hand as the right side.

[0031] The specific working process of the full-automatic kneader of this application is as follows: By placing the material in the material box of the automatic feeding rack 13, the track of the automatic feeding rack 13 is of type f, which can lift the material box to directly above the kneader and accurately place it into the material slot of the kneader. The material is extruded or cut by the pressing device 2, so that the material is initially formed and mixed evenly to prepare for subsequent processing. Then, the material enters the roller area for secondary pressing. Through the rotation and pressure of the rollers, the density and uniformity of the material are further improved. The pressed material is tamped back and forth by the manipulator device 4 to further mix the material, making its components more uniform and improving the performance and quality of the finished product. Among them, the material remaining on the rollers can be cleaned by adjusting the angle of the scraper device 3.

[0032] Example 1: As Figure 2 and Figure 3 shown, there is a blade on the pressing roller 22 of the pressing device 2 of this application, and the blade is detachably connected to the pressing roller 22, specifically one of adhesive bonding, welding or bolt connection.

[0033] The blades can be evenly distributed at consistent intervals, or unevenly distributed on the inner and outer sides. According to different material characteristics, the blades on the pressing roller 22 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 irregularly. The design of the pressing roller 22 with blades can not only press the material, but also be used to cut the material during the pressing process, facilitating subsequent processing and treatment.

[0034] Example 2: As Figure 4 and Figure 5 shown, different from Example 1, the pressing roller 22 of the pressing device 2 of this application is integrally formed and has a smooth outer cylindrical surface after meticulous processing, which can perform ordinary pressing on the material and is suitable for occasions where cutting is not required, such as simple flattening or compaction operations.

[0035] Example 3: The pressing support 21 in this application is specifically in the shape of a capital letter "J", which includes: two left and right feet and a support panel formed by connecting the tops of the feet. The tops of the feet are inclined, and the inclination angle is 15-30°. Therefore, the support panel formed between the feet is also inclined at a certain angle relative to the horizontal plane. The pressing support 21 can provide an inclined extrusion to the material, and the inclination angle can be adjusted according to different material characteristics.

[0036] In addition, a number of fixing blocks 24 are provided on the top of the support panel. The fixing blocks 24 are arranged at uniform or non-uniform intervals. The fixing blocks 24 on the left and right sides are connected to the guide rod 26 through the guide rod seat 25. The middle fixing block 24 is fixedly connected with a blank holding cylinder 23. The detachable design facilitates the replacement of parts for subsequent part damage and updates.

[0037] Example 4: As Figure 6 and Figure 7 shown, the scraper device 3 is manually adjusted. By manually rotating the adjustment mechanism 33 provided on the tool rest fixing plate 32 and using the principle of the screw-nut pair, the scraper 34 makes a linear motion in the axial direction of the roller, thereby realizing the adjustment of the gap between the scraper 34 and the roller surface. By observation, the position of the scraper 34 can be accurately controlled to meet the cleaning requirements of rubber compounds with different thicknesses. This adjustment method is simple and intuitive, without the need for an additional power source, and is suitable for working scenarios with relatively low requirements for adjustment accuracy and low operation frequencies.

[0038] Example 5: As Figure 8 and Figure 9 shown, different from Example 4, the scraper device 3 is electrically adjusted. Power is provided by the driving cylinder 331 to drive the first adjustment seat 332 and the second adjustment seat 333 to swing, and then drive the scraper 34 located on the scraper tool rest 31 to move. The driving cylinder 331 is one of an oil cylinder, a pneumatic cylinder, and an electric cylinder, which can quickly and accurately adjust the scraper 34 to the optimal position in complex process flows, effectively improving production efficiency and automation. For example, on a continuous rubber mixing production line, the gap size of the scraper 34 at each time period can be programmed and set in advance according to the characteristics of the rubber compound at different stages to achieve full-automatic rubber scraping and ensure stable rubber compound quality.

[0039] Whether it is manual adjustment or electric adjustment, the scraper device 3 closely fits the roller bearing seat 12 to ensure firm connection and avoid displacement of the scraper 34 due to vibration and other factors during the operation of the open mill, which affects the rubber scraping effect. At the same time, the material of the scraper 34 is selected as high-hardness and wear-resistant alloy steel, processed by a special heat treatment process, which can withstand the friction with the roller and the rubber compound for a long time, maintain a good edge state, effectively scrape off the rubber compound impurities adhered to the roller surface, and ensure the rubber mixing quality and operation efficiency of the open mill.

[0040] Example 6: As Figure 10 and Figure 11As shown, the manipulator device 4 moves the moving device 42 left and right on the manipulator base 41 by means of the left and right moving motor 435. Among them, the left and right moving motor 435 serves as the power source, and the power output by it is transmitted to the corresponding transmission mechanism, thereby driving the moving device 42 to perform left and right reciprocating movements according to the preset trajectory and speed requirements, so as to realize the position adjustment of the device in the horizontal direction, and further meet the operation requirements of different material positions.

[0041] Two different transmission mechanisms are adopted in the moving device 42. The rack 422 and the gear 432 are meshed and connected. When the left and right moving motor 435 operates, it will drive the gear 432 to rotate. Since the gear 432 and the rack 422 are meshed with each other, the rotational movement of the gear 432 will be converted into a linear movement of the rack 422 along its length direction, thereby driving the moving device 42 to move in the left and right directions. This meshing connection method can provide an accurate transmission ratio, ensuring that the moving speed and displacement of the moving device 42 can be executed according to the set parameters; the slide rail 421 and the slider 431 are in sliding fit connection. The slide rail 421 provides an accurate straight path for the movement of the moving device 42, restricting the displacement of the moving device 42 in other directions, enabling it to slide smoothly only along the set direction of the slide rail 421, effectively reducing the shaking and deviation during the movement, improving the accuracy and reliability of the device movement. At the same time, the sliding fit connection method also helps to reduce the frictional resistance during the movement, reducing the power loss to a certain extent, and ensuring that the left and right moving motor 435 can efficiently drive the moving device 42 to move.

[0042] There are two left and right ramming rollers 434 inside the manipulator device 4, and the front and back telescopic motor 433 is used to realize the front and back telescoping of the ramming rollers 434. When the moving device 42 moves to the leftmost side, the ramming roller 434 on the left side extends and is ready to start operating on the material; as the moving device 42 moves to the right, the extended ramming roller 434 will drive the material after being pressed by the roller to move to the opposite side. During this process, through the cooperation of the movement of the ramming roller 434 and the moving device 42, it is ensured that the material can move along the predetermined path and manner, realizing the guiding and turning of the material; when the moving device 42 is about to move to the rightmost side, the ramming roller 434 on the left side will retract, and at the same time, the ramming roller 434 on the right side will extend, preparing for the next stage of operation on the material.

[0043] The present application provides a fully automatic rubber mill. Through the mutual cooperation of a material pressing device 2, a scraping device 3, a manipulator device 4, an automatic feeding rack 13, and a power device 5, a high degree of automation in the rubber mixing process is achieved. The inclined material pressing device 2 can apply pressure accurately to ensure sufficient contact between the rubber material and the rollers, improving the rubber mixing efficiency; the scraping device 3 can clean the rubber material remaining on the surface of the rollers in a timely manner, avoiding adhesion and waste, ensuring continuous operation while ensuring the long-term operation of the equipment; the manipulator device 4 can move left and right to guide the material through the ramming roller 434; the automatic feeding rack 13 can stably supply raw materials, making the entire production process smooth and coherent, significantly increasing the output per unit time to meet the large-scale production requirements.

[0044] Automated equipment significantly reduces the dependence on manual labor. While reducing labor costs, it also reduces the labor intensity of workers, avoids potential safety hazards and quality fluctuations caused by manual operations, and improves the economic efficiency and stability of production.
