Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment for latex production, in particular to an accelerator mixing and grinding device for latex product production. Background Art

[0002] Accelerators are important additives in latex production. Rubber vulcanization is mainly carried out using sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators came into being. Accelerators added to rubber can activate the vulcanizer, thereby accelerating the cross-linking reaction between the vulcanizer and rubber molecules, achieving the effect of shortening the vulcanization time and reducing the vulcanization temperature.

[0003] When using accelerators in the latex production process, the accelerators need to be configured into a dispersion in advance for subsequent mixing and use. The accelerators need to be ground into the required material state, usually by placing them in a traditional ball mill or sand mill, adding an appropriate amount of tap water, and mixing and crushing for 48 hours.

[0025] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0026] 1. First, drive the stirring blade to rotate at high speed, stir and disperse the mixture containing the promoter at high speed for more than half an hour to make it evenly dispersed, and then stir at low speed for more than half an hour. Low-speed stirring can allow the bubbles generated by high-speed stirring to slowly escape, thereby reducing the viscosity of the dispersion; then drive the grinding roller to rotate through a driving mechanism, and the grinding roller drives a number of grinding media through a number of dispersers to disperse and grind the mixture. First grind at low speed for half an hour, then grind at medium speed for half an hour, and finally grind at high speed for more than half an hour until the mixture reaches the required particle size. Usually, the grinding can be completed in one or two hours; first stir to reduce the viscosity of the dispersion, so that the grinding efficiency can be improved during grinding and the particle size of the dispersion can be reduced. Multi-stage speed grinding is to avoid high-speed stirring at the beginning, which may cause the promoter to stick or block the screen. The whole machine completes the two functions of stirring and grinding, with a simple structure and high efficiency.

[0027] 2. During stirring, the reducer drives the driving shaft tube to rotate in the forward direction, and the driving shaft tube drives the driving ring to rotate through the first ratchet mechanism. At the same time, the driving shaft tube does not act on the grinding roller through the second ratchet mechanism. After the stirring is completed, when grinding is required, the reducer drives the driving shaft tube to rotate in the reverse direction. At this time, the driving shaft tube drives the grinding roller to rotate through the second ratchet mechanism, and at the same time, the driving ring is not driven to rotate through the first ratchet mechanism. Then, the same reducer is used to drive forward and reverse respectively, and the stirring blade and grinding roller are driven separately to achieve stirring and grinding respectively.

[0028] 3. When the reducer drives the drive shaft tube to rotate in the opposite direction, the second drive seat is driven to rotate through the second ratchet mechanism. The gear ring in the inner cavity of the second drive seat serves as the active part, and the sun gear on the grinding roller serves as the driven part. At this time, the overall speed-up transmission is in the opposite direction of the sun gear and the gear ring, that is, the direction of the grinding roller and the direction of the drive shaft tube are opposite. The speed-up transmission can facilitate the subsequent high-speed grinding operation of the grinding roller.

[0029] 4. When the cylinder is in a vertical state, a number of grinding media enter the medium storage bin, and then the reducer drives the drive shaft tube to rotate, thereby driving the drive ring to rotate. The drive ring drives the third magnet to rotate synchronously through the first magnet, and the third magnet drives the sealing plate to rotate, thereby aligning the shielding part with the medium storage bin, thereby sealing the medium storage bin and preventing the grinding media from escaping. When the shielding part completely blocks the medium storage bin, as the sealing plate rotates, the drive block in the limit groove can abut against the other end of the limit groove when the shielding part of the sealing plate rotates to just cover the medium storage bin, thereby preventing the sealing plate from rotating excessively. Then the drive ring rotates at high speed, and the stirring blade is driven to rotate at high speed through the adsorption action of the first magnet and the second magnet, while the sealing plate remains stationary.

[0030] 5. When the mixing operation is completed, the push cylinder drives the cylinder to a horizontal state, and the reducer drives the drive shaft tube in reverse, and then drives the grinding roller to rotate through the second ratchet mechanism and the planetary speed-increasing member. Since the grinding roller and the drive shaft tube have opposite directions, the grinding roller and the mixing blade and the sealing plate have the same direction. When the grinding roller rotates, the driving block is driven to rotate. The driving block first moves from one end of the limit groove to the other end, and then abuts against the limit groove, and then drives the sealing plate to rotate, so that the groove is aligned with the medium storage bin. The medium storage bin can be set as a conical cavity, and then under the action of gravity, a number of grinding media enter the cylinder from each medium storage bin, and are then driven by the grinding roller to perform the grinding operation.

[0031] 6. When the grinding roller is rotating, it can drive the sealing plate to rotate through the driving block, and the sealing plate can drive the driving ring where the first magnet is located to rotate through the third magnet. The first magnet can drive the stirring blade to rotate synchronously, and then during grinding, it can drive the mixed material, which helps to improve the grinding efficiency.

DETAILED DESCRIPTION

[0041] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Reference Figures 1 to 7 As shown, this embodiment provides an accelerator mixing and grinding device for latex product production, including a base 1, a grinding cylinder 2 and a driving mechanism 3, wherein the driving mechanism 3 is fixedly arranged at one end of the grinding cylinder 2, and the grinding cylinder 2 is rotatably arranged on the base 1; it also includes a push cylinder 8, the two ends of the push cylinder 8 are respectively hinged to the base 1 and the cylinder body 21, and the cylinder body 21 is pushed to rotate on the base 1 by the push cylinder 8, so that the cylinder body 21 is in a vertical or horizontal state, so as to respectively realize the dispersing stirring and grinding steps.

[0044] like Figure 3-Figure 5As shown, the grinding cylinder 2 includes a cylinder 21, a grinding roller 22, and a stirring blade 23. One end of the grinding roller 22 coaxially extends into the cylinder 21, and the grinding roller 22 is rotatably connected to the cylinder 21. The driving mechanism 3 drives the grinding roller 22 to rotate; a plurality of dispersers 24 are arranged on the outer wall of the grinding roller 22, and a plurality of grinding media 25 are arranged in the cylinder 21; when the cylinder 21 is in a horizontal state, the grinding roller 22 drives the plurality of dispersers 24 to rotate, thereby giving the grinding media 25 sufficient kinetic energy to collide with the promoter particles to generate shear force, so that the promoter is crushed and dispersed into smaller particles; at the same time, zirconium oxide beads are used as the grinding media 25. The zirconium oxide beads themselves are easy to clean, have high hardness, and are more wear-resistant than glass beads and natural sand.

[0045] More specifically, the stirring blade 23 is rotatably arranged on the grinding roller 22, and a plurality of medium storage bins 26 are arranged around the grinding roller 22 at one end of the stirring blade 23 which is close to the cylinder 21 and rotatably connected to the grinding roller 22. The medium storage bins 26 are communicated with the cylinder 21, and the medium storage bins 26 are used to store a plurality of grinding media 25 when the cylinder 21 is in a vertical state;

[0046] At the same time, if Figure 4 As shown, an annular sliding cavity 27 is provided between the medium storage bin 26 and the inner wall of the cylinder 21, and the sliding cavity 27 is communicated with the outside of the cylinder 21;

[0047] A driving ring 4 is coaxially rotated at one end of the cylinder 21, one end of the driving ring 4 extends into the sliding cavity 27 and is provided with a plurality of first magnets 41 in a circular array, a plurality of second magnets 231 are provided in a circular array at the bottom of the stirring blade 23, the plurality of second magnets 231 correspond one-to-one to the plurality of first magnets 41 and the magnetic poles of the ends close to each other are opposite; the driving mechanism 3 drives the driving ring 4 to rotate.

[0048] In specific implementation, when grinding the promoter, the cylinder 21 is made vertical by pushing the cylinder 8, and then 10 parts of the promoter and 10 parts of water are added. If necessary, 0.05-0.2 parts of the dispersant are added. The dispersant can be a non-ionic dispersant CF-10. Then, the driving ring 4 is driven to rotate by the driving mechanism 3, thereby driving the first magnets 41 to rotate. The first magnets 41 are attracted to the second magnets 231 respectively, and then the second magnets 231 are driven to rotate while the first magnets 41 rotate, thereby driving the stirring blades 23 to rotate. The stirring blades 23 are first driven to rotate at a high speed, and the mixture containing the promoter is stirred and dispersed at a high speed for more than half an hour to make it dispersed evenly, and then stirred at a low speed for more than half an hour. The low-speed stirring can allow the bubbles generated by the high-speed stirring to slowly escape, thereby reducing the viscosity of the dispersion.

[0049] After the mixture consisting of the accelerator, water and dispersant is evenly stirred, the push cylinder 8 drives the cylinder 21 to be horizontal, and then the top opening of the medium storage bin 26 is tilted to be horizontal, and a plurality of grinding media 25 flow out from the plurality of medium storage bins 26 into the cylinder 21, and then the driving mechanism 3 drives the grinding roller 22 to rotate, and the grinding roller 22 drives a plurality of grinding media 25 through a plurality of dispersers 24 to disperse and grind the mixture, first grind at a low speed for half an hour, then grind at a medium speed for half an hour, and finally grind at a high speed for more than half an hour until the mixture reaches the required particle size, and the grinding can usually be completed in one or two hours.

[0050] Through the above stirring and grinding methods, the viscosity of the dispersion is first stirred to reduce, so that the grinding efficiency can be improved during grinding and the particle size of the dispersion can be reduced. The multi-stage speed grinding is to avoid high-speed stirring at the beginning, which may cause the promoter to stick or block the screen. The whole machine completes the two functions of stirring and grinding, with a simple structure and high efficiency.

[0051] More specifically, Figure 1-4 As shown, the driving mechanism 3 includes a reducer 31 and a driving shaft tube 32. The driving shaft tube 32 is coaxially rotatable with the cylinder 21. The output end of the reducer 31 is connected to the driving shaft tube 32 through a synchronous pulley transmission.

[0052] The end of the drive shaft tube 32 close to the cylinder 21 is connected to the drive ring 4 through the first ratchet mechanism 5; the drive shaft tube 32 is connected to the grinding roller 22 through the second ratchet mechanism 6; the first ratchet tooth 521 of the first ratchet mechanism 5 and the second ratchet tooth 621 of the second ratchet mechanism 6 are inclined in opposite directions.

[0053] More specifically, Figure 3-6 As shown, the first ratchet mechanism 5 also includes a first driving seat 51, a first ratchet ring 52 and a first pawl 53. The first ratchet ring 52 is coaxially arranged at the end of the driving shaft tube 32. The inner cavity of the first ratchet ring 52 is annularly arranged with a plurality of first ratchet teeth 521. The first driving seat 51 is coaxially arranged on the driving ring 4. A plurality of first pawls 53 are arranged in an annular array on the first driving seat 51. The first pawl 53 is rotatably connected to the first driving seat 51 and meshes with the first ratchet tooth 521 through a first torsion spring.

[0054] Further, such as Figure 3-7 As shown, the second ratchet mechanism 6 also includes a second driving seat 61, a second ratchet ring 62 and a second pawl 63. The second ratchet ring 62 is coaxially arranged inside the driving shaft tube 32. The inner cavity of the second ratchet ring 62 is annularly provided with a plurality of second ratchet teeth 621. The second driving seat 61 is coaxially sleeved on the grinding roller 22. A plurality of second pawls 63 are arranged in an annular array on the second driving seat 61. The second pawl 63 is rotatably connected to the second driving seat 61 and meshes with the second ratchet teeth 621 through a second torsion spring.

[0055] In specific implementation, during stirring, the reducer 31 drives the driving shaft tube 32 to rotate in the forward direction, and the driving shaft tube 32 drives the driving ring 4 to rotate through the first ratchet mechanism 5, and at the same time, the driving shaft tube 32 does not act on the grinding roller 22 through the second ratchet mechanism 6. After the stirring is completed, when grinding is required, the reducer 31 drives the driving shaft tube 32 to rotate in the reverse direction. At this time, the driving shaft tube 32 drives the grinding roller 22 to rotate through the second ratchet mechanism 6, and at the same time, the driving ring 4 is not driven to rotate through the first ratchet mechanism 5, and then the same reducer 31 is used to drive forward and reverse respectively, and the stirring blade 23 and the grinding roller 22 are driven separately to achieve stirring and grinding respectively.

[0056] More specifically, Figure 4 and 7 As shown, the second drive seat 61 is annular, and a seat ring 64 is coaxially arranged at one end of the second drive seat 61, and the seat ring 64 is rotatably connected to the inner wall of the drive shaft tube 32; thereby ensuring that the second drive seat 61 is rotatably connected to the drive shaft tube 32. At the same time, a gear ring 65 is arranged in the inner cavity of the second drive seat 61, a sun gear 66 is sleeved on the grinding roller 22, and a plurality of planetary gears 67 are arranged in an annular array at the end of the cylinder 21, and the planetary gears 67 are meshed with the sun gear 66 and the gear ring 65.

[0057] In specific implementation, when the reducer 31 drives the driving shaft tube 32 to rotate in the opposite direction, the second ratchet mechanism 6 drives the second driving seat 61 to rotate, and the ring gear 65 in the inner cavity of the second driving seat 61 serves as the active part, and the sun gear 66 on the grinding roller 22 serves as the driven part. At this time, the whole is a speed-up transmission, and the transmission ratio is generally 0.25-0.67. The direction of rotation of the sun gear 66 is opposite to that of the ring gear 65, that is, the direction of rotation of the grinding roller 22 is opposite to that of the driving shaft tube 32. The speed-up transmission can help the subsequent high-speed grinding operation of the grinding roller 22.

[0058] More specifically, Figure 3-5 As shown, it also includes a sealing plate 7, on which a plurality of grooves 71 are arranged in an array, and shielding portions 72 are formed between adjacent grooves 71. The sealing plate 7 is rotated to make the plurality of grooves 71 correspond one-to-one with the plurality of medium storage bins 26, or to make the plurality of shielding portions 72 correspond one-to-one with the plurality of medium storage bins 26. After the grooves 71 correspond one-to-one with the medium storage bins 26, the grinding medium 25 enters the medium storage bin 26 under the action of gravity, and then the sealing plate 7 is rotated to make the shielding portions 72 correspond to the medium storage bin 26, so that the medium storage bin 26 can be blocked to prevent the internal grinding medium 25 from escaping when the stirring blade 23 is stirring. Although there are multiple medium storage bins 26 to isolate and store the grinding medium 25, and the grinding medium 25 is difficult to escap, the presence of the sealing plate 7 can better ensure the storage of the grinding medium 25 to prevent the stirring operation of the stirring blade 23 from being affected.

[0059] The second magnet 231 is located between the sliding cavity 27 and the cylinder 21; a plurality of third magnets 73 are arranged in an annular array on the outer periphery of the sealing plate 7, and the plurality of third magnets 73 are located at the end of the first magnet 41 away from the second magnet 231 and correspond one to one with the plurality of first magnets 41, and the magnetic poles of the third magnet 73 and the first magnet 41 close to each other are opposite and attract each other;

[0060] A plurality of driving blocks 221 are disposed around the grinding roller 22 , and a plurality of limiting grooves 74 are disposed in a circular array on the inner side of the sealing plate 7 . The number of the limiting grooves 74 is the same as the number of the grooves 71 , and the driving blocks 221 are placed in the limiting grooves 74 .

[0061] In specific implementation, when the cylinder 21 is in a vertical state, a number of grinding media 25 enter the medium storage bin 26, and then the reducer 31 drives the driving shaft tube 32 to rotate, thereby driving the driving ring 4 to rotate, and the driving ring 4 drives the third magnet 73 to rotate synchronously through the first magnet 41, and the third magnet 73 drives the sealing plate 7 to rotate, thereby aligning the shielding portion 72 with the medium storage bin 26, thereby blocking the medium storage bin 26 and preventing the grinding media 25 from escaping. When the shielding portion 72 completely blocks the medium storage bin 26, as the sealing plate 7 rotates, the driving block 221 in the limiting groove 74 can abut against the other end of the limiting groove 74 when the shielding portion 72 of the sealing plate 7 rotates to just cover the medium storage bin 26, thereby preventing the sealing plate 7 from excessive rotation. Then the driving ring 4 rotates at high speed, and the stirring blade 23 is driven to rotate at high speed through the adsorption action of the first magnet 41 and the second magnet 231, while the sealing plate 7 remains stationary.

[0062] When the mixing operation is completed, the push cylinder 8 drives the cylinder body 21 to be in a horizontal state, and the reducer 31 drives the driving shaft tube 32 in reverse, and then drives the grinding roller 22 to rotate through the second ratchet mechanism 6 and the planetary speed-increasing member. Since the grinding roller 22 and the driving shaft tube 32 have opposite directions, the grinding roller 22 has the same direction as the mixing blade 23 and the sealing plate 7. When the grinding roller 22 rotates, the driving block 221 is driven to rotate. The driving block 221 first moves from one end of the limiting groove 74 to the other end, and then abuts against the limiting groove 74, and then drives the sealing plate 7 to rotate, so that the groove 71 is aligned with the medium storage bin 26. The medium storage bin 26 can be set as a conical cavity, and then under the action of gravity, a number of grinding media 25 enter the cylinder body 21 from each medium storage bin 26, and are then driven by the grinding roller 22 to perform the grinding operation.

[0063] When the grinding roller 22 is rotating, it can drive the sealing plate 7 to rotate through the driving block 221, and the sealing plate 7 can drive the driving ring 4 where the first magnet 41 is located to rotate through the third magnet 73. The first magnet 41 can drive the stirring blade 23 to rotate synchronously, and then during grinding, it can drive the mixed material, which helps to improve the grinding efficiency.

[0064] It should be noted that, since the grinding roller 22 needs to rotate, the positions of the driving block 221 and the medium storage bin 26 need to be positioned when the grinding roller 22 stops. The rotation position of the driving roller can be detected by a photoelectric sensor or a proximity sensor. The proximity sensor can be set on the cylinder 21, and then a corresponding sensing block is set on the grinding roller 22 to achieve accurate resetting of the driving block 221, so that after the cylinder 21 is set vertically, the sealing plate 7 is driven to block the top of the medium storage bin 26. At the same time, the motor of the reducer 31 adopts a servo stepper motor to facilitate the accurate resetting of the grinding roller 22.

[0065] One end of the cylinder 21 away from the driving mechanism 3 is cooperated with a cylinder cover 28, and a discharge port 211 is also provided on the cylinder 21. When the cylinder 21 is vertically charged, the cylinder cover 28 is opened to charge, and then the barrel cover is closed to stir and grind, and finally discharged from the discharge port 211. A filtering mechanism needs to be provided at the discharge port 211 to intercept unnecessary or substandard substances.

[0066] More specifically, a spiral cooling channel 29 is provided on the cylinder 21, and a feed joint and a discharge joint are respectively provided at both ends of the spiral cooling channel 29. The medium pump and the feed joint are connected through a pipeline, and the cooling medium in the cooling medium storage tank is transported to the spiral channel. The cooling medium is transported from the discharge joint back to the cooling medium storage tank via the pipeline. The cooling medium storage tank is provided with a radiator for cooling the cooling medium. The spiral cooling channel 29 is used to transport the cooling medium and to take away the heat generated inside the cylinder 21 during grinding. Some pressure gauges, thermometers and other equipment equipped in traditional grinders also need to be set on the cylinder 21, and a mechanical seal 9 needs to be set between the grinding roller 22 and the cylinder 21.
