Description

Technical Field

[0001] This invention relates to the field of tire vulcanizing bladder production technology, and in particular to a tire vulcanizing bladder mixing apparatus and its usage method. Background Technology

[0002] Tire vulcanizing bladders are hollow, thin-walled rubber products used in tire vulcanizing machines. They are inserted into the inner cavity of the tire blank to be vulcanized, and then a heating medium is introduced to cooperate with the vulcanizing machine for shaping and vulcanization operations. The production of tire vulcanizing bladders mainly includes processes such as internal mixing, open mixing, and vulcanization. Internal mixing is a crucial step in tire vulcanizing bladder production, determining the uniformity of the mixing of rubber compound and various additives, and affecting the final performance of the tire vulcanizing bladder. During internal mixing, rubber compound, processing aids, vulcanization aids, etc., are added to an internal mixer. The internal mixer is equipped with a pair of rotors of specific shapes that rotate relative to each other. Under a closed state with adjustable temperature and pressure, the rubber compound is intermittently mixed, allowing various additives to be fully dispersed and mixed in the rubber compound. After mixing, the rubber compound is removed to obtain the compounded rubber. In the existing technology, internal mixers are usually divided into bottom-top-discharge type and tilting-discharge type according to different unloading methods. The tilting-discharge type refers to the internal mixer being tilted 90 degrees after mixing, so that the top opening of the internal mixer is rotated to the side, and then the compounded rubber is removed from the opening.

[0003] Patent application number CN202010238893.9 discloses an improved internal mixer's tilting system, feeding device, and method. The system includes a tilting cylinder with its root mounted on a main base, a tilting bearing seat positioned between the main base and the mixing chamber of the internal mixer, a tilting drive arm connected between the tilting cylinder and the mixing chamber, and tilting rotary joints respectively positioned at both ends of the mixing chamber. A meshing cooling water outlet and a meshing cooling center hole are respectively connected to the corresponding tilting rotary joints. The drive device includes a drive motor mounted on the main base, a drive motor connected to a transmission gear coupling, and a keyed connection to... The transmission speed ratio gear at the end of the rotor after meshing; the above design is compact and easy to use, but it has the following problems: the tire vulcanizing bladder rubber has a certain stickiness, and rubber residue is easy to be left when unloading, which requires regular cleaning. During cleaning, workers need to use tools to reach into the mixing chamber and scrape off the rubber on the mixing chamber and rotor little by little. Due to the narrow space of the mixing chamber and the obstruction of the rotor, the operation is inconvenient, the cleaning efficiency is low, and the labor intensity is high. Therefore, there is an urgent need for a tire vulcanizing bladder mixing device that is easy to clean, can reduce the labor intensity of workers, and improve the cleaning efficiency.

[0013] This invention provides a method for using a tire vulcanizing bladder mixing apparatus, comprising the following steps:

[0014] Step S1, Mixing: Place the rubber compound, processing aids and vulcanizing aids into the mixing chamber. Press down the top bolt mechanism to seal the top opening of the mixing chamber. Then turn on the rotary drive mechanism. The rotor rotates relative to the rubber compound and processing aids to mix. After mixing is completed, the top bolt mechanism moves up and disengages from the mixing chamber. The flip drive mechanism drives the mixing chamber to rotate 90 degrees so that the opening of the mixing chamber faces forward. Then unload the material from the opening of the mixing chamber.

[0015] Step S2, Cleaning: The flip drive mechanism drives the mixing chamber to rotate 90 degrees, so that the opening of the mixing chamber faces forward. Then, the locking mechanism releases the lock between the mixing chamber and the two side covers. The mixing chamber is moved backward, so that the mixing chamber is completely separated from the two side covers and the rotor pair. Then, the rotor pair and the mixing chamber are cleaned separately. After cleaning, the locking mechanism relocks the mixing chamber and the two side covers. The flip drive mechanism drives the mixing chamber to rotate 90 degrees in the opposite direction, so that the opening of the mixing chamber faces upward, in preparation for the next mixing.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] 1. The mixing chamber of the present invention consists of a "U"-shaped mixing chamber, two side covers, and a locking mechanism for locking the mixing chamber and the two side covers. The mixing chamber is designed in a "U" shape, allowing the rotor to pass through the top opening of the mixing chamber. When cleaning is required, the mixing chamber and the two side covers can be separated. After separation, the rotor and the mixing chamber can be cleaned separately, avoiding cleaning dead corners and greatly improving the cleaning effect and cleaning efficiency.

[0018] 2. The slide groove of the mixing chamber is slidably connected to the second slider of the side cover. The locking grooves on the two sliding plates in the locking mechanism can lock the position of the second slider on the side cover, so that the side cover and the mixing chamber cannot slide against each other. By pushing the sliding plate, the locking groove can be disengaged from the second slider. At this time, the second slider is unlocked, and the side cover and the mixing chamber can slide against each other. The locking and unlocking of the mixing chamber and the side cover can be easily achieved by pushing the sliding plate, which is convenient to operate.

[0019] 3. The two third sliders on the sliding plate slide in conjunction with the two horizontal grooves on the mixing chamber, which can further improve the stability of the sliding connection between the sliding plate and the mixing chamber; the annular cover plate is connected to the two side covers, which can position the two side covers and improve the structural stability on the one hand, and prevent the material from falling into the chute of the mixing chamber during feeding, thereby improving the cleanliness of production and the stability of equipment operation.

[0020] 4. The transfer mechanism can automatically remove the mixing chamber from the two side covers after it has been rotated 90 degrees, reducing the labor intensity of workers and improving work efficiency;

[0021] In summary, the locking mechanism in this invention can lock or unlock the "U"-shaped mixing chamber and the two side covers of the mixing chamber, quickly separating the mixing chamber from the side covers and the rotor, facilitating thorough cleaning of the mixing chamber, reducing the labor intensity of workers, and improving cleaning efficiency.

[0039] Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention. Example 1

[0040] Combined with appendix Figure 1-13 This embodiment provides a tire vulcanizing bladder mixing device, including a base 1. The base 1 is provided with a frame 2, two supports 3 and a rotary drive mechanism 4. A mixing chamber 5 is provided between the two supports 3. The mixing chamber 5 is provided with a rotor pair 6 connected to the rotary drive mechanism 4. The mixing chamber 5 includes a U-shaped mixing chamber 51 with an upward opening. Side covers 52 are respectively sealed on the left and right sides of the mixing chamber 51. A locking mechanism 53 is provided between the mixing chamber 51 and the side covers 52. The frame 2 is provided with an upper top bolt mechanism 7 that can block the top opening of the mixing chamber 5 and a flipping drive mechanism 8 that drives the mixing chamber 5 to rotate.

[0041] In the above technical solution, the unmentioned parts of the mixing device, such as the heating and cooling system, grease pump, and control system, are all set up in accordance with the conventional methods of existing technology. In the prior art, the hot and cold medium circulation pipeline of the heating and cooling system is usually installed on the left side of the base 1, and the rotating shaft of the rotor pair 6 is provided with a hot and cold medium circulation passage connected to the hot and cold medium circulation pipeline. The side wall or bottom of the mixing chamber 51 can be provided with auxiliary heating devices such as electric heating plates. In this invention, the mixing chamber 51 is U-shaped, so that the rotor pair 6 can pass through the top opening of the mixing chamber 51. When cleaning is required, the mixing chamber 51 and the two side covers 52 can be separated, while the rotor pair 6 and the two side covers 52 are still in a rotating connection state, and the mixing chamber 51 is separated from the side covers 52 and the rotor pair 6. The locking mechanism 53 can be a commonly used detachable locking structure such as a bolt and nut assembly, which can lock the mixing chamber 51 and the side covers 52. 2. Locking is sufficient; During mixing, place the rubber compound, processing aids, and vulcanizing aids into the mixing chamber 5. The top bolt mechanism 7 presses down to seal the top opening of the mixing chamber 5. Then, turn on the rotary drive mechanism 4. The rotor pair 6 rotates to mix the rubber compound and processing aids. After mixing, the top bolt mechanism 7 moves upward to disengage from the mixing chamber 5. The flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees so that the opening of the mixing chamber 5 faces forward. Then, unload from the opening of the mixing chamber 5. When it is necessary to clean the mixing chamber 5 and the rotor pair 6, the flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees so that the opening of the mixing chamber 5 faces forward. Then, the locking mechanism 53 releases the lock between the mixing chamber 51 and the two side covers 52. Move the mixing chamber 51 backward so that the mixing chamber 51 is completely separated from the two side covers 52 and the rotor pair 6. Then, clean the rotor pair 6 and the mixing chamber 51 respectively.

[0042] In the above technical solution, the mixing chamber 5 consists of a "U"-shaped mixing chamber 51, two side covers 52, and a locking mechanism 53 for locking the mixing chamber 51 and the two side covers 52. The mixing chamber 51 is designed in a "U" shape, allowing the rotor pair 6 to pass through the top opening of the mixing chamber 51. When cleaning is required, the mixing chamber 51 and the two side covers 52 can be separated. After separation, the rotor pair 6 and the mixing chamber 51 can be cleaned separately, avoiding cleaning dead corners and greatly improving the cleaning effect and cleaning efficiency.

[0043] In one specific technical solution, the rotary drive mechanism 4 includes a drive motor 41 and a reduction gearbox 42 with two output ends connected to the drive motor 41. The rotor pair 6 includes a meshing first rotor 61 and a second rotor 62. The shafts of the first rotor 61 and the second rotor 62 rotate through the side cover 52 of the mixing chamber 5 and are connected to the output end of the reduction gearbox 42.

[0044] In the above technical solution, the drive motor 41 is fixed on the base 1, and the reduction gearbox 42 is suspended and can rotate together with the mixing chamber 5. This is common knowledge in the field and will not be described in detail.

[0045] In one specific technical solution, the upper top bolt mechanism 7 includes a hydraulic cylinder 71, an upper top bolt 72 connected to the piston rod of the hydraulic cylinder 71, and a receiving chamber 73 for receiving the upper top bolt 72. The lower end face of the upper top bolt 72 and the upper end face of the inner cavity of the mixing chamber 51 are respectively provided with two intersecting semi-circular grooves. In the internal mixing state, such as... Figure 8 As shown, the top bolt 72 and the semi-circular groove of the mixing chamber 51 enclose a mixing cavity concentric with the rotor pair 6.

[0046] In the above technical solution, the two intersecting semicircular grooves refer to the two semicircular grooves having a partial overlap, and the overlapping part is the meshing area of ​​the first rotor 61 and the second rotor 62.

[0047] In one specific technical solution, the outer side wall of the side cover 52 is provided with a first bushing 521 that rotates with the shaft of the first rotor 61 and a second bushing 522 that rotates with the second rotor 62; the first bushing 521 near the gearbox 42 is rotatably connected to a bracket 3, and the second bushing 522 is connected to the flange of the gearbox 42; the first bushing 521 away from the gearbox 42 is rotatably connected to another bracket 3, and the flipping drive mechanism 8 includes a cylinder 81 hinged to the frame 2, the piston rod of the cylinder 81 is hinged to a rocker arm 82, and the rocker arm 82 is connected to the first bushing 521.

[0048] In the above technical solution, the rocker arm 82 is preferably located at the free end of the first bushing 521 away from the gearbox 42. The rotation axes of the first rotor 61 and the second rotor 62 extend to the left into the first bushing 521 and the second bushing 522 on the left side, and extend to the right into the first bushing 521 and the second bushing 522 on the right side and are connected to the rotary drive mechanism 4. This is a conventional setting in the art and will not be described in detail. The cylinder 81 of the tilting drive mechanism 8 is mounted on the frame 2. When the cylinder 81 extends or retracts, it can drive the rocker arm 82 and the first bushing 521 connected to the rocker arm 82 to rotate. The rocker arm 82 can adopt any suitable structure and be hinged to the piston rod of the cylinder 81, as long as it can rotate with the extension and retraction of the piston rod.

[0049] In one specific technical solution, the locking mechanism 53 includes two sliding plates 531 mirror-distributed at the left and right ends of the mixing chamber 51. Each sliding plate 531 has a vertically extending opening 532 extending downward from its upper end and a horizontally provided spring groove 533. A locking groove 534 communicating with the opening 532 is provided on the rear side of the opening 532. The left and right ends of the mixing chamber 51 are respectively provided with a sliding groove 511 extending downward from its upper end and a first slider 512 that slides in cooperation with the spring groove 533. One end of the spring 535 is connected to the first slider 512, and the other end is connected to the spring groove 533. The side cover 52 is provided with a second slider 523 that passes through the locking groove 534 and slides in cooperation with the sliding groove 511. The sliding plate 531 can slide backward under the push of an external force, so that the second slider 523 disengages from the locking groove 534 and enters the opening 532.

[0050] In the above technical solution, two springs 535 are preferably provided, located on the front and rear sides of the first slider 512 respectively, which can improve the reset stability; the sliding fit between the first slider 512 and the spring groove 533 and the second slider 523 and the slide groove 511 can adopt any suitable form, for example, the first slider 512 and the second slider 523 can be T-blocks, dovetail blocks, etc., and the spring groove 533 and the slide groove 511 can be T-grooves and dovetail grooves respectively; the locking groove 534 can limit and lock the second slider 523, preventing the second slider 523 from sliding vertically along the slide groove 511. When the sliding plate 531 is pushed backward, the locking groove 534 moves backward, releasing the lock on the second slider 523, and the second slider 523 disengages from the lock. After the groove 534 enters the through-hole 532, the through-hole 532 coincides with the slide groove 511. The second slider 523 can pass through the through-hole 532 and move vertically along the slide groove 511. As long as the mixing chamber 51 is pushed down, the mixing chamber 51 can be completely separated from the side cover 52. It should be noted that the above process is the unlocking step in the initial state (i.e., when the opening of the mixing chamber 5 is facing upward). In actual unlocking, the mixing chamber 5 needs to be rotated 90 degrees beforehand so that the opening of the mixing chamber 5 is forward and the front side wall of the mixing chamber 51 is rotated to the bottom. At this time, the direction changes. Push the sliding plate 531 upward to make the locking groove 534 move upward and separate from the second slider 523. Then push the mixing chamber 51 and the locking mechanism 53 backward to separate the mixing chamber 51 and the two side covers 52.

[0051] In one specific technical solution, the sliding plate 531 has the same shape as the mixing chamber 51. The two sides of the opening of the sliding plate 531 are respectively provided with through holes 532. At least two locking grooves 534 are provided that communicate with one through hole 532. The number of sliding grooves 511 is the same as the number of through holes 532. The number of second sliders 523 is the same as the number of locking grooves 534.

[0052] In the above technical solution, the sliding plate 531 has the same shape as the mixing chamber 51, which can improve the regularity of the inner cavity of the mixing chamber 5 and improve the mixing effect. The fact that the sliding plate 531 has the same shape as the mixing chamber 51 means that the sliding plate 531 has the same upward-opening "U" shape structure as the mixing chamber 51. The bottom of the inner cavity of the sliding plate 531 is also two semi-circular arcs concentric with the mixing chamber 51 and with the same diameter. Since the sliding plate 531 is plate-shaped and the mixing chamber 51 is a cavity, the thickness (i.e., the left and right length) of a single sliding plate 531 is much smaller than the thickness of the mixing chamber 51. The sliding plate 531 has openings 532 on both sides of the opening, and the mixing chamber 51 has the same number of sliding grooves 511 as the openings 532, which can improve the stability of the sliding connection between the mixing chamber 51 and the side cover 52. Multiple locking grooves 534 are provided to improve the locking stability between the mixing chamber 51 and the side cover 52. In this embodiment, there are two locking grooves 534 that communicate with one opening 532. One locking groove 534 is located near the bottom of the opening 532, and the other locking groove 534 is located near the top of the opening 532.

[0053] In one specific technical solution, a third slider 536 is provided on both sides of the opening of the sliding plate 531. The mixing chamber 51 is provided with a horizontal groove 513 that slides with the third slider 536. The upper end face of the mixing chamber 51 is provided with an upper flange 514 extending to the left and right ends, and the lower end face of the mixing chamber 51 is provided with a lower flange 515 extending to the left and right ends. The upper end face of the sliding plate 531 slides against the upper flange 514, and the lower end face of the sliding plate 531 slides against the lower flange 515. The upper end faces of the two side covers 52 are connected to an annular cover plate 54, and the annular cover plate 54 abuts against and covers the upper end face of the mixing chamber 51.

[0054] In the above technical solution, the two third sliders 536 on a sliding plate 531 slide in conjunction with the two horizontal grooves 513 on the mixing chamber 51, which can further improve the stability of the sliding connection between the sliding plate 531 and the mixing chamber 51. The third sliders 536 and the horizontal grooves 513 can adopt any suitable structure, such as T-blocks with T-grooves, dovetail blocks with dovetail grooves, etc. The upper flange 514 and the lower flange 515 can protect the sliding plate 531 and limit its movement, further improving the sliding stability of the sliding plate 531. The annular cover plate 54 is connected to the two side covers 52, which can position the two side covers and improve structural stability. On the other hand, it can prevent materials from falling into the chute 511 of the mixing chamber 51 during feeding, improving production cleanliness and equipment operation stability.

[0055] In one specific technical solution, the base 1 is provided with a transfer mechanism 9, which includes a tray 91 located directly below the mixing chamber 51. The upper surface of the tray 91 is provided with two protruding ribs 911. The tray 91 is connected to a displacement drive mechanism 92 that drives its back-and-forth movement and a lifting drive mechanism 93 that drives its lifting. When the mixing chamber 5 is rotated 90 degrees, the tray 91 can rise and abut against the mixing chamber 51. The two protruding ribs 911 can be inserted between the upper flange 514 and the lower flange 515 and push the sliding plate 531 to move upward, unlocking the side cover 52 and the mixing chamber 51.

[0056] In the above technical solution, the transfer mechanism 9 can automatically remove the mixing chamber 51 after it has been rotated 90 degrees from the two side covers 52, reducing the labor intensity of workers and improving work efficiency. When cleaning is required, the mixing chamber 5 is rotated 90 degrees. At this time, the protrusions 911 on the tray 91 are facing the sliding plate 531. The lifting drive mechanism 93 drives the tray 91 to rise. The tray 91 abuts against the mixing chamber 51. The two protrusions 911 are inserted between the upper flange 514 and the lower flange 515, pushing the sliding plate 531 to move upward. This causes the locking groove 534 to move upward, disengage from the second slider 523, and enter the through-hole 532. After the second slider 523 is unlocked, it can slide freely along the slide groove 511. At this time, the displacement drive mechanism 92 drives the tray 91 to move backward, so that the mixing chamber 51 is away from the two side covers 52 and the rotor pair 6. Finally, the mixing chamber 51 and the rotor pair 6 are cleaned to remove the adhering adhesive.

[0057] In one specific technical solution, the displacement driving mechanism 92 includes a lead screw 921 rotatably mounted on a base 1, a nut seat 922 mounted on the lead screw 921, and a first servo motor 923 that drives the lead screw 921 to rotate. The base 1 is provided with a displacement groove 11 that slides with the nut seat 922. The lifting driving mechanism 93 includes a threaded cylinder 931 and a threaded rod 932 that are threaded together. The threaded cylinder 931 is rotatably connected to the nut seat 922, and the threaded rod 932 is fixedly connected to the support plate 91. The nut seat 922 is provided with a second servo motor 933, which is connected to a first gear 934. The threaded cylinder 931 is provided with a second gear 935 that meshes with the first gear 934.

[0058] In the above technical solution, it is preferable to provide two threaded cylinders 931 and threaded rods 932, which are symmetrically arranged on both sides of the first servo motor 923 to further improve the lifting stability.

[0059] The working principle and process of this embodiment are as follows: During mixing, the rubber compound, processing aids, and vulcanizing aids are placed into the mixing chamber 5. The upper top bolt mechanism 7 presses down to seal the top opening of the mixing chamber 5. Then, the rotary drive mechanism 4 is turned on, and the rotor pair 6 rotates to mix the rubber compound and processing aids. After mixing, the upper top bolt mechanism 7 moves upward to disengage from the mixing chamber 5. The flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees so that the opening of the mixing chamber 5 faces forward. Then, the material is unloaded from the opening of the mixing chamber 5. During cleaning, the flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees so that the opening of the mixing chamber 5 faces forward. The lifting drive mechanism 93 in the transfer mechanism 9 drives the pallet 91 to rise. The pallet 91 abuts against the mixing chamber 51. The two protruding ribs 911 are inserted between the upper flange 514 and the lower flange 515, pushing the sliding plate 531 to move upward. The spring 535 deforms and accumulates elastic force. The locking groove 534 on the sliding plate 531 moves upward to disengage from the second slider 523 on the side cover 52. After the second slider 523 enters the opening 532 and unlocks, it can slide freely along the groove 511 on the mixing chamber 51. The displacement drive mechanism 92 drives the tray 91 to move backward, so that the mixing chamber 51 is away from the two side covers 52 and the rotor pair 6. Finally, the mixing chamber 51 and the rotor pair 6 are cleaned to remove the adhering adhesive. After cleaning, the displacement drive mechanism 92 drives the tray 91 and the mixing chamber 51 on the tray 91 to move forward and reset. The second slider 523 on the side cover 52 is reinserted into the groove 511 of the mixing chamber 51. The lifting drive mechanism 93 drives the tray 91 to descend and reset. The two protrusions 911 on the tray 91 move away from the sliding plate 531. The spring 535 releases its elastic force to push the sliding plate 531 to descend and reset. The locking groove 534 re-engages with the second slider 523, and the second slider 523 is locked. The flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees in the opposite direction, so that the opening of the mixing chamber 5 faces upward, ready for the next mixing. Example 2

[0060] Combined with appendix Figure 1-13 This embodiment provides a method for using a tire vulcanizing bladder mixing device, including the following steps:

[0061] Step S1, Mixing: Place the rubber compound, processing aids and vulcanizing aids into the mixing chamber 5. Press down the top bolt mechanism 7 to seal the top opening of the mixing chamber 5. Then turn on the rotary drive mechanism 4. The rotor pair 6 rotates to mix the rubber compound and processing aids. After mixing is completed, the top bolt mechanism 7 moves up and disengages from the mixing chamber 5. The flip drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees so that the opening of the mixing chamber 5 faces forward. Then unload the material from the opening of the mixing chamber 5.

[0062] Step S2, Cleaning: The flipping drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees, so that the opening of the mixing chamber 5 faces forward. Then, the locking mechanism 53 releases the lock between the mixing chamber 51 and the two side covers 52, and moves the mixing chamber 51 backward, so that the mixing chamber 51 is completely separated from the two side covers 52 and the rotor pair 6. Then, the rotor pair 6 and the mixing chamber 51 are cleaned respectively. After cleaning, the locking mechanism 53 relocks the mixing chamber 51 and the two side covers 52. The flipping drive mechanism 8 drives the mixing chamber 5 to rotate 90 degrees in the opposite direction, so that the opening of the mixing chamber 5 faces upward, in preparation for the next mixing.
