Description

Technical Field

[0001] The present invention relates to the technical field of raw rubber plasticizing equipment, and more specifically, to a raw rubber plasticizing device for rubber raw materials. Background Art

[0002] A mill is short for an open rubber mill. It is a rubber processing machine with exposed rollers used in rubber factories to prepare plasticized rubber, mixed rubber, or for hot rolling and profiling. Its main working components are two hollow rollers or drilled rollers that rotate in opposite directions inward. The roller on the operator's side is called the front roller, which can be moved horizontally forward and backward manually or electrically to adjust the roller gap to meet the operation requirements; the rear roller is fixed and cannot be moved back and forth. The two rollers are generally of the same size and rotate relative to each other at different speeds. The raw rubber or rubber compound is drawn into the gap between the two rollers as the rollers rotate and is subjected to strong shearing forces to achieve the purpose of plasticizing or mixing.

[0003] After retrieval, a patent with the Chinese patent application number CN202421097540.1 discloses a raw rubber plasticizing device for rubber raw materials, which includes a frame, a main roller, a secondary roller, and a driving mechanism for driving the main roller and the secondary roller to rotate synchronously in opposite directions. The driving mechanism is installed on the frame and is respectively connected to the main roller and the secondary roller. A material taking mechanism is provided at the bottom of the frame. The material taking mechanism includes a slide rail, a collection box, a driving gear, and a power component. The slide rail is fixedly installed at the bottom of the frame, the collection box is slidably installed in the slide rail, and the collection box is located between the main roller and the secondary roller. One side of the collection box extends outward with a fixing plate, and a tooth groove matching the edge teeth of the driving gear is opened at the bottom of the fixing plate. The power component is installed outside the frame, and the output end of the power component is fixedly connected to the driving gear. The driving gear meshes with the bottom of the fixing plate. By starting the power component to drive the driving gear to rotate, the fixing plate drives the collection box to move in the slide rail, thereby reducing the interference of manual collection, improving the safety of the equipment, and preventing danger during manual collection;

[0004] After retrieval, a patent with the Chinese patent application number CN202123055520.7 discloses an open mill for rubber production, which includes a frame, and also includes a front roller and a rear roller that can move axially, a driving component for driving the front roller and the rear roller to operate, a cutting device fixedly connected to the frame, and a transmission component for driving the cutting device to operate. The present invention relates to the technical field of rubber production equipment. By setting the driving component, when using the front roller and the rear roller to process recycled rubber or rubber compound, the front roller and the rear roller perform axial reciprocating movements under the cooperation of the guide groove and the slider. At this time, the raw rubber or rubber compound located between the two rollers is subjected to longitudinal shearing forces and also transverse shearing forces, thereby improving the plasticizing effect of the raw rubber or the mixing effect of the rubber compound, reducing the number of repeated open milling times, improving production efficiency, and shortening production time;

[0005] Although the above patent can perform simple rubber mixing functions, the following deficiencies still exist during use:

[0006] 1. Frequent manual intervention: During the extrusion process, rubber tends to spread to both sides, and it is necessary for workers to use a scraper to scrape the rubber back to the middle of the extrusion roller, resulting in low efficiency and potential safety hazards.

[0007] 2. Poor adaptability: The width of the traditional extrusion roller is fixed and cannot be adjusted according to the process requirements, restricting the applicable range of the equipment.

[0008] 3. Defects in material collection: The fixed material collection tray is prone to causing rubber accumulation or slipping, resulting in material waste.

[0009] Therefore, there is an urgent need for a raw rubber plasticizing device for rubber raw materials to solve the above problems. Summary of the Invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the scheme of this application:

[0031] 1. The reciprocating parts are matched with the scraper, and based on the working principle of reciprocating motion, the automatic centering scraping is realized during the rubber mixing process, which solves the problem of safety hazards and low efficiency of manual scraping in the prior art. The baffle rod of the reciprocating parts periodically contacts the lever of the adjustable driving part, driving the reciprocating frame to slide horizontally and link the scraper to move synchronously along the axial direction of the extrusion roller, so that the scraper blade always covers the rubber diffusion area. This mechanical linkage design scrapes off the overflowed rubber in real time and guides it to the middle of the roller, eliminating the need for manual intervention, preventing operators from contacting high-temperature rollers, and improving scraping efficiency.

[0032] 2. By matching the adjustable drive component with the reciprocating component, based on the mechanical adjustment principle of the double-threaded screw and the lever, the width of the extrusion roller is adjusted steplessly, solving the problem of poor process adaptability caused by the fixed roller width of traditional equipment. The rotation of the double-threaded screw drives the two sets of adjustment blocks to move in the opposite direction, changing the distance between the levers, and then adjusting the lateral stroke of the reciprocating frame. This structure enables the axial movement range of the first extrusion roller to be precisely controlled to adapt to the requirements of different rubber widths. Continuous width adjustment within the range can be achieved without replacing the roller, reducing equipment downtime and significantly improving the flexibility of the production line.

[0033] 3. Through the coordination of the set driving rack, gear set and material receiving parts, based on the gear rack meshing transmission principle, the synchronous movement of plasticizing and material receiving is realized, solving the problem of rubber accumulation and waste caused by the fixed receiving tray. The reciprocating motion of the driving rod is transmitted to the support shaft through the meshing of the driving rack and the first gear, and the tray is driven to move horizontally through the second gear and the driven rack. The gear ratio matching design synchronizes the tray movement speed with the rubber extrusion rate, ensuring that the rubber falls accurately into the center area of ​​the tray, improving the rubber collection rate, and avoiding the risk of manual cleaning of high-temperature rubber.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0045] As Figure 1-8 shown, a raw rubber plasticizing device proposed in this embodiment includes a chassis 1 and a fixed frame 2 fixedly connected to the top of the chassis 1, and further includes:

[0046] A support frame 3, fixedly connected to the inner wall of the chassis 1;

[0047] An adjustable driving component, slidably connected to the outer wall of the support frame 3;

[0048] The extrusion shaft 21 is rotatably connected to the inner wall of the fixed frame 2. A sliding sleeve 211 is slidably connected to the outer wall of the extrusion shaft 21, and the sliding sleeve 211 is limited by a limiting strip provided on the inner wall and a limiting groove opened on the outer wall of the extrusion shaft 21. A first extrusion roller 212 is also fixedly connected to the outer wall of the sliding sleeve 211;

[0049] The mounting frame 22 is fixedly connected to the top wall of the fixed frame 2. Scrapers 221 that match the first extrusion roller 212 are fixedly connected to both supporting ends of the mounting frame 22. An adjustable extrusion component that cooperates with the first extrusion roller 212 is also slidably connected to the inner wall of the mounting frame 22. It should be noted that the first extrusion roller 212 is internally provided with a heating structure to realize the heating of the surface of the first extrusion roller 212;

[0050] The reciprocating component is slidably connected to one end of the support frame 3 away from the bottom frame 1, and the reciprocating component is used to drive the sliding sleeve 211 to perform reciprocating motion;

[0051] The material receiving component is slidably connected to the inner wall of the bottom frame 1 through two groups of sliding rods 12;

[0052] The support shaft 11 is rotatably connected to the inner wall of the machine body 1. A first gear 111 and a second gear 112 that respectively cooperate with the adjustable driving component and the material receiving component are also fixedly connected to the outer wall of the support shaft 11;

[0053] The bottom frame 1 serves as a basic load-bearing platform and is fixedly connected to the fixed frame 2 by welding or bolts to form a stable rigid support system. Bearing mounting holes are opened on both sides of the fixed frame 2 to support the rotational movement of the extrusion shaft 21. The support frame 3 is vertically fixed to the inner side of the bottom frame 1, and its guiding chute and the driving rod 31 form a sliding pair to ensure that the driving rod 31 only moves in the vertical direction, providing constraint conditions for subsequent power transmission.

[0054] As Figure 3-8 shown, as a preferred implementation manner, on the basis of the above manner, further, the adjustable driving component includes a driving rod 31 slidably connected to the outer wall of the support frame 3, a driving ring 311 fixedly connected to the top of the driving rod 31, a driving rack 312 fixedly connected to the end away from the driving ring 311 and meshing with the first gear 111, a driving group fixedly connected to the side wall of the fixed frame 2, and an adjusting part fixedly connected to the outer wall of the driving rod 31 and cooperating with the reciprocating component.

[0055] As Figure 2-7 shown, as a preferred implementation manner, on the basis of the above manner, further, the driving group includes a first driving motor 32 fixedly connected to the side wall of the fixed frame 2, a rotating plate 321 fixedly connected to the output end of the first driving motor 32, and a driving column 322 fixedly connected to the end of the rotating plate 321 away from the output end of the first driving motor 32. The driving column 322 is slidably connected to the driving ring 311.

[0056] As shown in Figure 1-8 the figure, as a preferred embodiment, on the basis of the above method, further, the adjusting part includes a connecting frame 33 fixedly connected to both side walls of the driving rod 31 and a double-threaded screw rod 331 rotatably connected between two groups of connecting frames 33. The double-threaded screw rod 331 is respectively threadedly connected with an adjusting block 332 through two groups of external threads with opposite thread directions on the outer wall. A shifting rod 333 cooperating with the reciprocating member is fixedly connected to the side wall of the adjusting block 332. A third driving motor 334 for driving the double-threaded screw rod 331 is also fixedly connected to the side wall of one of the connecting frames 33;

[0057] The output shaft of the first driving motor 32 is fixedly connected with a rotating plate 321, and the driving column 322 is eccentrically installed at the edge of the rotating plate 321. When the rotating plate 321 rotates, the driving column 322 slides in the driving ring 311, converting the rotational motion into the vertical reciprocating motion of the driving rod 31.

[0058] The driving rack 312 at the bottom of the driving rod 31 meshes with the first gear 111, driving the support shaft 11 to rotate, and then through the meshing of the second gear 112 and the driven rack 122, the power is transmitted to the receiving tray 121.

[0059] As shown in Figure 1-8 the figure, as a preferred embodiment, on the basis of the above method, further, the reciprocating member includes a reciprocating frame 34 slidably connected to one end of the support frame 3 away from the chassis 1 and a stop rod 341 fixedly connected to the middle of the sliding end of the reciprocating frame 34. The stop rod 341 cooperates with the shifting rod 333, and the two support ends of the reciprocating frame 34 are respectively rotatably connected to the sliding sleeves 211.

[0060] As shown in Figure 1-8 the figure, as a preferred embodiment, on the basis of the above method, further, two groups of springs 342 symmetrically distributed about the support frame 3 are sleeved on the outer wall of the sliding end of the reciprocating frame 34.

[0061] As shown in Figure 1-8 the figure, as a preferred embodiment, on the basis of the above method, further, the receiving component includes a tray 121 connected to the top of the chassis 1 through two sliding rods 12 and a driven rack 122 fixedly connected to the bottom wall of the tray 121. The driven rack 122 is meshed and connected with the second gear 112. The meshing transmission of the moving rack 312 and the first gear 111 converts the linear motion of the driving rod 31 into the rotation of the support shaft 11. When in use, the receiving tray is placed on the tray, the second gear 112 meshes with the driven rack 122, driving the tray 121 to reciprocate horizontally along the sliding rod 12, ensuring that the rubber material evenly falls into the tray and avoiding accumulation and dropping.

[0062] As shown in Figure 1-8As shown, as a preferred embodiment, on the basis of the above method, further, the adjustable extrusion part includes an adjusting frame 222 slidably connected to the inner wall of the mounting frame 22, a second extrusion roller 223 rotatably connected to the adjusting frame 222 and cooperating with the first extrusion roller 212, and an extrusion cylinder 224 fixedly connected to the top wall of the mounting frame 22. The output end of the extrusion cylinder 224 is fixedly connected to the adjusting frame 222;

[0063] The two sections of the double-threaded screw 331 have opposite thread directions and are respectively threadedly connected to two groups of adjusting blocks 332. When the third driving motor 334 drives the double-threaded screw 331 to rotate, the two groups of adjusting blocks 332 move towards or away from each other, driving the distance between the shift rods 333 to change synchronously.

[0064] When the driving rod 31 reciprocates, the shift rod 333 periodically pushes the stop rod 341, forcing the reciprocating frame 34 to slide horizontally along the support frame 3. The reciprocating frame 34 is connected to the sliding sleeve 211 through a hinge point, thereby driving the first extrusion roller 212 to axially move and realizing dynamic adjustment of the extrusion width.

[0065] The spring 342 is sleeved on the sliding end of the reciprocating frame 34 and provides a reset elastic force when the shift rod 333 disengages from the stop rod 341, ensuring the stability of the reciprocating frame 34 when it returns to its position.

[0066] As Figure 1-8 shown, as a preferred embodiment, on the basis of the above method, further, a second driving motor 23 is also fixedly connected to the top wall of the fixed frame 2. The output end of the second driving motor 23 is connected to the extrusion shaft 21 through a gear set.

[0067] As Figure 1-8 shown, as a preferred embodiment, on the basis of the above method, further, a machine shell 13 is also provided on the top of the machine base frame 1, and a control panel 131 is also provided on the side wall of the machine shell 13. It should be noted that a matching sensor should also be provided at the connection between the second extrusion roller 223 and the adjusting frame 222.

[0068] Specifically, when this rubber raw material raw rubber plasticizing device is in use: in the width adjustment and power start-up stage, the third driving motor 334 drives the double-threaded screw 331 to rotate, and the adjusting block 332 drives the shift rod 333 to move to the target distance. This distance determines the pushing amplitude of the shift rod 333 on the stop rod 341, and further controls the axial movement range of the first extrusion roller 212. The second driving motor 23 drives the extrusion shaft 21 to rotate through the gear set, and the first extrusion roller 212 rotates accordingly. The extrusion cylinder 224 pushes the adjusting frame 222 downward, so that the second extrusion roller 223 and the first extrusion roller 212 form a preset roller distance.

[0069] During the rubber plasticizing and scraping process, after the raw rubber is put into the gap between the two rollers, it is plasticized by the shear force. During the rolling process, the rubber diffuses to both sides due to lateral extension. At this time, the cutting edge of the scraper 221 is in close contact with the surface of the first extrusion roller 212. The scraper 221 is rigidly supported and tilted to force the overflowing rubber to be scraped off the roller surface and directed to the middle of the extrusion area. The installation angle of the scraper 221 is fine-tuned by the bolt adjustment mechanism to ensure that the flow direction of the rubber can be controlled during the scraping process to avoid secondary accumulation.

[0070] Dynamic width adjustment and pressure feedback: When the process requirements change, the third drive motor 334 drives the double-threaded screw 331 to rotate and change the spacing of the lever 333. During the reciprocating motion of the drive rod 31, the pushing distance of the lever 333 on the stopper 341 changes accordingly, so that the axial displacement range of the first extrusion roller 212 is dynamically adjusted to achieve stepless control of the extrusion width; the extrusion cylinder 224 has a built-in pressure sensor to monitor the pressure value of the second extrusion roller 223 in real time. If the viscosity of the rubber material changes and the extrusion force exceeds the threshold, the system automatically adjusts the cylinder output pressure to maintain the stability of the plasticizing process.

[0071] The reciprocating motion of the driving rod 31 is synchronously transmitted to the receiving tray 121, ensuring that the tray can move back and forth when the rubber material falls, thereby avoiding rubber accumulation.

[0072] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
