Abstract
Description
Technical Field
[0001] This invention relates to the field of rubber extruder technology, specifically to an intelligent extrusion device and method for producing styrene-butadiene rubber that is easy to clean. Background Technology
[0002] The production of styrene-butadiene rubber (SBR) products requires the raw SBR rubber to be compounded with other ingredients and then extruded through a rubber extruder. When changing ingredients or after production, the screw and die holder of the extruder used for extruding SBR products need to be disassembled, and the residual rubber material on the screw, die holder, and barrel cavity needs to be cleaned.
[0003] A search of existing technologies revealed that patent announcement number CN222372258U discloses a rubber extruder, which includes a barrel, a feed hopper, an extrusion mechanism, and an extrusion disc. The barrel has an installation port and a discharge port on each side. The feed hopper is detachably connected to the installation port. The extrusion mechanism includes a screw and a drive component. The screw is located inside the barrel, and the drive component is located on one side of the barrel and is connected to the screw for transmission. The extrusion disc is detachably connected to the discharge port, and an extrusion hole is located in the center of the extrusion disc.
[0004] Existing technology detachably connects the extrusion disc to the discharge port and the screw to the drive unit, allowing both the die holder and the screw to be removed for cleaning. However, this requires disassembly one by one, which is time-consuming and labor-intensive. Furthermore, the barrel needs to be heated before removing the screw and die holder to prevent residual adhesive from cooling and solidifying, thus facilitating removal and cleaning. However, even after the screw and die holder are removed, they are still prone to rapid heat loss due to separation from the barrel, making it difficult to remove the adhesive from the surface.

[0014] A method for an easy-to-clean intelligent extrusion apparatus for producing styrene-butadiene rubber, the method comprising the following steps: Step 1: After heating the inside of the barrel, the drive assembly drives the slide box and slide rod to move to the side away from each other, causing the screw to move to the left and move out of the barrel. The main mold base, the auxiliary mold base and the baffle all move to the right. At this time, the reset assembly moves on the connecting rod. Step 2: When the screw moves to the left and is removed from the barrel, the cleaning component cleans the uncured adhesive on the screw. After it is completely removed and cleaned, the screw is removed from the output shaft of the geared motor by the disassembly and assembly component and sent to the next process for deep cleaning. Step 3: When the reset assembly moves on connecting rod 2, the sub-mold base and baffle move forward and gradually begin to cover both sides of the main mold base. When it moves on connecting rod 3, the sub-mold base and baffle completely cover both sides of the main mold base, keeping the inside of the main mold base warm. When the drive assembly stops driving the slide bar to move, the main mold base can be removed from the top of the slide bar. At this time, the rear side of the reset assembly is no longer squeezed, causing the sub-mold base and baffle to reset backward, thereby exposing both sides of the main mold base for cleaning. Step 4: After cleaning the screw, main mold base and auxiliary mold base, clean the inside of the barrel.
[0015] Preferably, during the cleaning of the inside of the barrel in step four, the inside of the barrel is kept heated.
[0016] This invention provides an intelligent extrusion apparatus and method for producing styrene-butadiene rubber (SBR) that is easy to clean. Compared with the prior art, it has the following advantages: 1. This intelligent extrusion device and method for producing styrene-butadiene rubber (SBR) that facilitates cleaning uses a drive assembly to move the slide box and slide rod in opposite directions. This allows the slide box to move the screw to the left out of the barrel via a disassembly assembly. Simultaneously, the slide rod moves the main die holder, auxiliary die holder, baffle, and reset assembly to the right away from the barrel, eliminating the need for manual disassembly and saving time and effort. Furthermore, the screw can be automatically cleaned as it moves out of the barrel via the drive assembly, preventing excessive heat loss and cleaning difficulties. Once the screw has completely moved out of the barrel and cleaning is complete, the disassembly assembly automatically detaches the screw, allowing it to be removed from the output shaft of the geared motor for further cleaning in the next process.
[0017] 2. This intelligent extrusion device and method for producing styrene-butadiene rubber, which is easy to clean, involves a sliding rod that drives the main die holder, sub-die holder, baffle, and reset assembly to move to the right away from the barrel. This movement is achieved by gradually moving along connecting rod one, connecting rod two, and connecting rod three, allowing the sub-die holder and baffle to gradually move forward and eventually completely cover both sides of the main die holder. This provides insulation to the inside of the main die holder, preventing excessive heat loss and making cleaning difficult when cleaning the inside. This technical solution allows for the simultaneous removal of the screw and main die holder from the barrel, and automatic cleaning and insulation of the main die holder while the screw is being removed, preventing excessive heat loss and difficulty in cleaning after moving away from the barrel. Furthermore, the screw can be automatically detached for deeper cleaning in the next process step. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] See Figures 1-10 The present invention provides the following two technical solutions: First embodiment: A smart extrusion device for producing styrene-butadiene rubber that is easy to clean includes a base 1. The base 1 is equipped with a controller 2, a barrel 3, a drive assembly 4, and a cleaning assembly 17. The barrel 3 has a feed inlet and heating elements, which are existing technologies and will not be described in detail here. The drive assembly 4 is used to drive the slide box 5 and the slide rod 6 to move in opposite directions. The slide box 5 is equipped with a reduction motor 7. The output shaft of the reduction motor 7 is connected to a screw 8 located inside the barrel 3 through a disassembly assembly 9. In this way, the reduction motor 7 drives the disassembly assembly 9 to rotate, which in turn drives the screw 8 to rotate. The cleaning assembly 17 is used to clean the screw 8 that has been removed from the barrel 3. The top of the slide rod 6 is slidably sleeved with the main mold base 10. When the slide rod 6 moves, it can drive the main mold base 10 to move. The left and right sides of the main mold base 10 are respectively attached to the auxiliary mold base 11 and the baffle 12. The main mold base 10 and the auxiliary mold base 11 together form a molding die. The auxiliary mold base 11 is attached to the machine barrel 3. The auxiliary mold base 11 and the baffle 12 are both connected to the reset assembly 13. The reset assembly 13 is attached to the connecting rod 14. The connecting rod 14 is connected to the forward-tilted connecting rod 2 15. The connecting rod 2 15 is connected to the connecting rod 3 16. The connecting rod 14 and the connecting rod 3 16 are both connected to the machine base 1. When the reset assembly 13 moves on the connecting rod 2 15, it can drive the auxiliary mold base 11 and the baffle 12 to move forward.
[0022] The drive assembly 4 includes several evenly arranged support seats 41. A servo motor 42 is detachably connected to the left support seat 41. The output shaft of the servo motor 42 is connected to the rotating shaft 43. The servo motor 42 is powered by existing technology and can drive the rotating shaft 43 to rotate the required number of revolutions. The rotating shaft 43 is rotatably connected to several support seats 41 through bearings. A thread 1 44 is provided on the left side of the rotating shaft 43, and a thread 2 45 is provided on the right side of the rotating shaft 43. The threads of thread 1 44 and thread 2 45 have opposite directions. A slide box 5 that is slidably connected to the base 1 is screwed onto thread 1 44, and a slide rod 6 that is slidably connected to the base 1 is screwed onto thread 2 45. The rotating shaft 43 drives thread 1 44 and thread 2 45 to rotate synchronously, so that the sliding box 5 and the slide rod 6 move in opposite directions.
[0023] Compared to the screw 8, the slide bar 6 does not need to move a long distance. Therefore, the pitch of thread 1 44 can be greater than the pitch of thread 2 45. In this way, when rotating for the same amount of time, the screw 8 moves a greater distance than the main mold base 10. For ease of control, the controller 2 is also electrically connected to the servo motor 42 and the geared motor 7. This can be done wired or wirelessly. If wired, the cable length can be set as needed to avoid dragging. In particular, for the geared motor 7 which needs to move laterally, the servo motor 42 needs to be a model with a larger torque to achieve stable operation.
[0024] The assembly / disassembly component 9 includes a drive shaft 91 rotatably connected to the slide box 5 via bearings. The drive shaft 91 is connected to the output shaft of the geared motor 7. A driven shaft 92 is slidably sleeved on the outside of the drive shaft 91. The driven shaft 92 can move laterally relative to the drive shaft 91 and can rotate with the drive shaft 91. Both ends of the driven shaft 92 are hinged with movable rods 93. Limiting rods 94, which are inserted into the screw 8, are hinged on both movable rods 93. To guide the limiting rods 94, guide rods 925 are slidably connected to both limiting rods 94. The guide rods 925 are fixedly connected to the rotating tube 918. Both ends of the rotating tube 918 are rotatably connected with connecting bearings 919. To make the outer rings of the connecting bearings 919 on both sides integrally connected, on both sides... Support rods 920 are evenly arranged circumferentially between the outer rings of the side connecting bearings 919. The outer ring of the left connecting bearing 919 is fixedly connected to the slide box 5. The driven shaft 92 is rotatably connected to the outside of the support bearing 95. The outer ring of the support bearing 95 is hinged to a movable rod 96. The bottom of the movable rod 96 is hinged to a mounting rod 97 that extends out of the slide box 5. The mounting rod 97 is slidably sleeved on the guide rod 98. The guide rod 98 is fixedly connected to the slide box 5. A return spring 910 connected to the slide box 5 is detachably connected to the mounting rod 97. A roller 99 is also provided on the mounting rod 97. The bottom of the roller 99 contacts the crossbar 911 provided on the machine base 1. The left end of the crossbar 911 is also provided with an upwardly inclined bar 912.
[0025] The rotation of the drive shaft 91 causes the driven shaft 92 to rotate, which in turn drives the movable rod 93 to rotate. This, in turn, drives the limiting rod 94, the guide rod 925, and the rotating tube 918 to rotate under the guidance of the connecting bearing 919, thereby driving the screw 8, which is fixed by the limiting rods 94 on both sides, to rotate.
[0026] When the driven shaft 92 rotates, the support bearing 95 ensures that the movable rod 96 does not need to rotate.
[0027] When the slide box 5 moves to the left, the rotary tube 918 moves to the left as well, which drives the screw 8 to move to the left and remove it from the barrel 3. During removal, the roller 99 rolls on the crossbar 911. When it is completely removed from the barrel 3, the roller 99 starts to roll on the diagonal bar 912, which compresses the return spring 910 and drives the mounting rod 97 to move upward. This causes the movable rod 96 to push the driven shaft 92 to move to the right along the drive shaft 91, which in turn pushes the limit rod 94 on the movable rod 93 to move on the guide rod 925, so that the limit rod 94 can be disengaged from the screw 8. This allows it to be automatically removed after being removed from the barrel 3, so that it can be moved to the next process for deep cleaning.
[0028] To improve sealing, a sealing sleeve 913 is provided at the bottom of the slide box 5. The sealing sleeve 913 fits snugly onto the mounting rod 97, and its part is cylindrical, which provides a good sealing effect.
[0029] The assembly / disassembly component 9 also includes protruding rods 914 on both sides of the outer ring of the support bearing 95. A groove 915 is laterally formed inside the slide box 5, which slides slidably with the protruding rods 914. This allows the support bearing 95 to slide laterally on the groove 915 via the protruding rods 914 when the driven shaft 92 moves laterally, providing a guiding effect. A positioning block 916 is provided at the left end of the screw 8, which is inserted into a fixing rod 917. The fixing rod 917 is fixedly connected to the inner wall of the rotating tube 918, thus providing a guiding effect when the screw 8 is installed. Furthermore, the rotating tube 918 can also drive the positioning block 916 to rotate via the fixing rod 917, instead of relying solely on the limiting rod 94 to drive the screw 8 to rotate, which can improve the structural strength. The outer ring of the right connecting bearing 919 is evenly provided with insert rods 921, and the outer ring of the right connecting bearing 919 is embedded with a sealing ring 922. The insert rods 921 are inserted into the barrel 3, which can position the right connecting bearing 919. The outer ring of the right connecting bearing 919 and the sealing ring 922 are in contact with the barrel 3, which can improve the sealing effect and reduce the entry and exit of gas.
[0030] The assembly and disassembly assembly 9 also includes rotating rods 923 located at both ends of the outer side of the driven shaft 92. The inner ring of the rotating tube 918 has an elongated groove 924. The rotating rods 923 are slidably connected to the elongated groove 924. When the driven shaft 92 rotates, the rotating rods 923 can directly drive the rotating tube 918 to rotate through the elongated groove 924, without relying solely on the movable rod 93, which further improves the structural strength. Moreover, when the driven shaft 92 needs to move laterally, the rotating rods 923 can move laterally on the elongated groove 924 without being affected. That is, the rotation and removal of the screw 8 are not simultaneous, but only rotate during operation.
[0031] The reset assembly 13 includes a second roller 131 that contacts the first connecting rod 14. The second roller 131 is mounted on a slide 132 that is connected to both the secondary mold base 11 and the baffle 12. That is, when the slide 132 moves, the secondary mold base 11 and the baffle 12 move accordingly. The slide 132 is slidably connected to a slide rail 133, which is fixedly connected to the main mold base 10. A second reset spring 134 is detachably connected between the slide 132 and the main mold base 10. When the second roller 131 rolls on the first connecting rod 14, the secondary mold base 11 and the baffle 12 move. When it rolls on the second connecting rod 15, it can be compressed. The second return spring 134 causes the slide 132 to move forward, which in turn moves the secondary mold base 11 and the baffle 12 forward. When moving on the second connecting rod 15, it maintains the coverage on both sides of the main mold base 10 to achieve heat preservation. In order to ensure stable positioning when the secondary mold base 11 is reinstalled, the second insert rod 18 is evenly arranged on the left side of the secondary mold base 11 and inserted into the barrel 3. In order to improve the sealing performance, the second sealing ring 19 is embedded on the left side of the secondary mold base 11 and fits and connects to the barrel 3. The first connecting rod 14 has a certain distance, so that after the second insert rod 18 leaves the barrel 3, the secondary mold base 11 and the baffle 12 can move forward.
[0032] The second embodiment differs from the first embodiment in that: the cleaning assembly 17 includes a bearing seat 171 mounted on the base 1, the bearing seat 171 being rotatably connected to the rotating ring 172 via a bearing, the inner wall of the rotating ring 172 being uniformly provided with electric telescopic rods 173, the output end of the electric telescopic rods 173 being provided with a nylon brush 174, which provides good pre-cleaning effect on the adhesive on the screw 8, the outer wall of the rotating ring 172 being uniformly provided with teeth 175, and the rotating shaft 43 being provided with a gear 176 that meshes with the teeth 175, the rotating ring 172 being located outside the rotating tube 918 and located between the barrel 3 and To improve safety, a protective cover 177 is installed on the bearing housing 171 between the sliding boxes 5. The protective cover 177 covers the outside of the teeth 175 and gears 176. The controller 2 and the electric telescopic rod 173 are electrically connected, and wireless connection is used. For example, a wireless receiving and transmitting module is set up for control to avoid cable tangling. Of course, the power supply of the electric telescopic rod 173 can be achieved by setting a battery on the rotating ring 172. The purpose of the electric telescopic rod 173 is to ensure that the rotating tube 918 moves without obstruction, so it does not need to extend and retract continuously, and the rechargeable battery is sufficient.
[0033] The screw 8, which is blocked by the rotating tube 918, has no spiral blades, so there will be no adhesive material and no cleaning is required. When the rotating tube 918 moves the screw 8 to the left, after the rotating tube 918 leaves the nylon brush 174, the electric telescopic rod 173 can drive the nylon brush 174 to extend, and the gear 176 can also drive the teeth 175 to rotate, so that the rotating ring 172 drives the nylon brush 174 to clean the screw 8.
[0034] A method for a cleanable intelligent extrusion apparatus for producing styrene-butadiene rubber (SBR), employing a cleanable intelligent extrusion apparatus for SBR production according to a second embodiment, includes the following steps: Step 1: After heating the inside of the barrel 3, the drive assembly 4 drives the slide box 5 and slide rod 6 to move to the side away from each other. Specifically, the servo motor 42 drives the rotating shaft 43 to rotate, so that thread 1 44 and thread 2 45 rotate synchronously, so that the screw 8 moves to the left and moves out of the barrel 3. The main mold base 10, the auxiliary mold base 11 and the baffle 12 all move to the right. At this time, the roller 2 131 on the reset assembly 13 moves on the connecting rod 14, while the roller 1 99 rolls on the crossbar 911. Step Two: When the screw 8 moves to the left and exits the barrel 3, the cleaning assembly 17 cleans the uncured adhesive on the screw 8. Specifically, after the rotating tube 918 leaves the nylon brush 174, the electric telescopic rod 173 extends the nylon brush 174, and the rotating shaft 43 rotates, causing the gear 176 to rotate. This, in turn, causes the gear 176 to rotate the teeth 175, thereby causing the rotating ring 172 to drive the nylon brush 174 to clean the screw 8. After it is completely removed and cleaned, the screw 8 is removed from the output shaft of the reduction motor 7 using the disassembly assembly 9 and sent to the next process for deep cleaning. Specifically, when the slide box 5 moves to the left... When the rotating tube 918 moves to the left, it drives the screw 8 to move to the left and remove it from the barrel 3. During removal, the roller 99 rolls on the crossbar 911. When it is completely removed from the barrel 3, the roller 99 starts to roll on the inclined bar 912, which compresses the return spring 910 and drives the mounting rod 97 to move upward. This causes the movable rod 96 to push the driven shaft 92 to move to the right along the drive shaft 91, which in turn pushes the limit rod 94 on the movable rod 93 to move on the guide rod 925, so that the limit rod 94 can be disengaged from the screw 8. This allows it to be automatically removed after being removed from the barrel 3, so that it can be moved to the next process for deep cleaning. Step 3: When the roller 131 of the reset assembly 13 moves on the connecting rod 15, the sub-mold seat 11 and the baffle 12 move forward and gradually begin to cover both sides of the main mold seat 10. When it moves on the connecting rod 16, the sub-mold seat 11 and the baffle 12 completely cover both sides of the main mold seat 10, keeping the inside of the main mold seat 10 warm. When the drive assembly 4 no longer drives the slide bar 6 to move, the main mold seat 10 can be removed from the top of the slide bar 6. At this time, the rear side of the roller 131 of the reset assembly 13 is no longer squeezed by the connecting rod 16, causing the sub-mold seat 11 and the baffle 12 to reset backward, thereby exposing both sides of the main mold seat 10 for cleaning. Step 4: After cleaning the screw 8, main mold holder 10 and auxiliary mold holder 11, clean the inside of the barrel 3.
