Description

Technical Field

[0001] The invention belongs to the technical field of rubber production, and in particular relates to a rubber mixing production line. Background Art

[0002] Rubber products, represented by tires, are closely related to our lives. In the production process of rubber products, mixing is particularly important, which determines the production efficiency of the entire company and the quality of the final rubber products.

[0003] Problems with existing technologies:

[0004] At present, the mixing production lines used by enterprises with relatively large business scales, such as tires and conveyor belts, have high requirements for plant buildings, which are generally designed with four floors and up to 24 meters. For rubber mixing enterprises with small scale, they are all designed with one floor plant buildings, and the height is generally about 10 meters. Due to the limitation of plant buildings, they often use low-grade mixing equipment such as pressurized kneading lines. For such production lines, the ingredients need to be mixed offline by operators, and the materials are manually fed into the pressurized kneading machine. There are many operators and the labor intensity is high. In addition, the structure of the pressurized kneading machine determines that it has low production efficiency, low mixing quality and poor environmental protection. The workshop is dusty and the environment is bad. In addition, the traditional mixing line uses a hanging rod type rubber cooling machine. In order to prevent the film from slipping during the mobile cooling process, round nails will be set on the hanging rod. However, for relatively thin films, the round nails will pierce the film, affecting subsequent use. In short, the current production line has a low degree of automation, poor environmental protection, low production efficiency and poor mixing quality, which does not meet the overall requirements of green and high-quality development. When using a bucket elevator, the material it transports has temperature, which can easily cause damage and aging of the elevator. Moreover, the existing rubber produces toxic and harmful odors after heating, and most of them are treated through wind, activated carbon adsorption, combustion treatment, chemical treatment and other methods. Among them, activated carbon cannot completely adsorb toxic and harmful substances, and activated carbon needs to be replaced frequently. Summary of the invention

[0059] Among them, an oil weighing device is provided inside the raw rubber online weighing device 1, a powder weighing device is provided between the falling type internal mixer 3 and the conveying device 2 4, the falling type internal mixer 3 includes a power system for driving the rotor to rotate, the rotor is driven by the main shaft to rotate the blades, and the material is mixed. In addition, the falling type internal mixer 3 is also provided with a feed port and a discharge port, the discharge port is used to connect with the top of the feed end of the conveying device 2 4, and the open mixer 6 includes a corresponding setting and a roller that rotates to squeeze the material.

[0060] Furthermore, its working principle is:

[0061] The raw rubber online weighing device 1, the oil weighing device, the conveying device 1 2, the powder weighing device, the conveying device 2 4 are used to prepare the material formula, and are automatically put into the falling type internal mixer 3 for sealed mixing to generate mixed rubber. The mixed rubber is put into the open mixer 6 through the bucket elevator 5 for additional mixing and cutting, and is coated with a release agent and cooled through the rubber cooling machine 7 before being discharged into sheets.

[0062] Furthermore, the falling type internal mixer 3 also includes a heating device for heating materials, a cooling device for cooling molten materials, a stirring and mixing device, a control system, a material feeding and discharging device, a waste material discharging device, and a frame and a base.

[0063] According to the above structure, in the production process of the rubber mixing production line, the steps include the following:

[0064] The raw rubber online weighing device 1, the oil weighing device, the conveying device 1 2, the powder weighing device, and the conveying device 2 4 are used to realize the material formulation, and achieve preliminary mixing during the conveying process, and the mixed and formulated materials are put into the sealed mixing interior of the falling type internal mixer 3 to achieve the stirring, heating, cooling of the materials, and the output of the generated waste and finished products.

[0065] The mixed rubber is then fed into an open mixing mill 6 via a bucket elevator 5, and the open mixing mill 6 is used to cut and shape the mixed rubber. After the mixing is completed, the mixed rubber is fed from the bucket elevator into the open mixing mill 6, and the mixed rubber is compressed into a desired shape and size through the rotation of the rollers and the extrusion force for further processing or molding.

[0066] Please refer to Figure 3-12 In order to cool down the bucket elevator 5 and avoid damage to the bucket elevator 5, the following method is used:

[0067] Please refer to the details Figure 3 and Figure 4 A group of cooling pipes 509 are set up inside the bucket elevator 5. The cooling pipes 509 form a loop through the infusion pipes 505, the liquid pump 506 and the cooling liquid tank 508 connected at both ends. The refrigeration device 507 set on one side of the cooling liquid tank 508 is used to cool the inside of the cooling liquid tank 508.

[0068] Furthermore, through the air pipe 511 erected inside the bucket elevator 5, memory baffles 512 are evenly provided on the outside of the air pipe 511, and a negative pressure fan 510 is provided at the bottom of the air pipe 511 and connected thereto, which is used to discharge the heat inside the bucket elevator 5 and further discharge the harmful gas generated inside the bucket elevator 5.

[0069] Please refer to Figure 5 , Figure 6 as well as Figure 8 The memory baffle 512 is fixedly sleeved on the outside of the air pipe 511, and the memory baffle 512 covers the outside of the negative pressure port 513. The cross-sections on both sides of the bottom of the memory baffle 512 are arc-shaped. As the internal temperature of the bucket elevator 5 increases, the memory baffle 512 curls upward from the bottom.

[0070] According to the above structure, the memory baffle 512 and the air pipe 511 are fixedly connected by interference fit or welding.

[0071] The working principle of the memory baffle 512 is that the memory baffle 512 is initially in full fit against the outside of the air pipe 511. After the temperature inside the bucket elevator 5 rises, the bottom sides of the memory baffle 512 are heated, so that the bottom is deformed. However, since the cross-sections of the bottom sides of the memory baffle 512 are arc-shaped, they can only curl from the bottom of the memory baffle 512 under the stress of the shape of the memory baffle 512 itself.

[0072] The way in which the bucket elevator 5 provides power is as follows, please refer to Figure 7 :

[0073] First, the bucket elevator 5 is used to drive the bucket 501 fixedly installed on the surface of the conveyor belt 502 to move through the annular conveyor belt 502. A positioning mounting frame 503 is provided at the top of the bucket elevator 5, and a driving device 504 is fixedly installed on the positioning mounting frame 503.

[0074] Furthermore, the driving device 504 is fixedly mounted with a driving motor 5041 , a transmission wheel 5043 and a transmission 5044 via a positioning mounting frame 503 , and the driving motor 5041 and the transmission belt 5042 are connected in transmission via the sleeved transmission belt 5042 .

[0075] Furthermore, the transmission wheel 5043 is rotatably installed inside the transmission 5044, and a side gear is located inside the transmission 5044 for transmission. The side gear is fixed with a driving rod 5045, and the driving rod 5045 is connected to a rotating shaft 5046 through a flange transmission. A rotating wheel 5047 is fixed to the outside of the rotating shaft 5046. The inner sides of both ends of the conveyor belt 502 are provided with a rotating wheel 5047 rotatably connected thereto, and the rotating wheel 5047 at the other end is fixedly installed by the rotating shaft 5046 running through the inside thereof.

[0076] According to the above structure, during the use of the bucket elevator 5, power is provided by the driving motor 5041 and is transmitted to the transmission wheel 5043 and the transmission 5044 in sequence. A screw is fixed on one side of the bottom of the transmission wheel 5043 for meshing and transmitting with the side gear inside the transmission 5044, thereby realizing the transmission of kinetic energy to the transmission 5044 and the driving rod 5045. After the driving rod 5045 rotates, the bucket elevator 5 is driven to operate through the rotation of the rotating shaft 5046 and the rotating wheel 5047.

[0077] In addition, please refer to Figure 4The cooling pipe 509 is in an "S" shape. One end of the top of the cooling pipe 509 is fixedly installed on one end inside the bucket elevator 5 through the infusion pipe 505. The bottom end of the cooling pipe 509 is fixedly connected to the outside of the air pipe 511, and is fixedly installed on one side of the bottom of the bucket elevator 5 through the bottom end of the air pipe 511. The top end of the air pipe 511 passes through the outside of the bucket elevator 5 and is fixedly connected to the bucket elevator 5.

[0078] Furthermore, a mounting frame for fixedly connecting with the bucket elevator 5 is provided on the outer side of the cooling pipe 509 and the air pipe 511 located inside the bucket elevator 5 , and negative pressure ports 513 are opened on both sides of the air pipe 511 .

[0079] According to the above structure, by installing the cooling pipe 509 and the air pipe 511 inside the bucket elevator 5, the internal temperature of the bucket elevator 5 can be controlled, and the harmful gas generated inside the bucket elevator 5 can be transported out.

[0080] Of course, after the air pipe 511 discharges the harmful gas, the air needs to be filtered through the filter cartridge 514 fixed at the top of the air pipe 511.

[0082] Furthermore, a clip strip 5145 adapted to the elastic clip plate 5144 is provided on the inner side of the mounting slide 5141, and slide grooves 51421 adapted to the clip strip 5145 are provided on both sides of the barrel 5142, a slot 51422 is provided on the top of the barrel 5142, and a convex plug-in net 51424 adapted to be plugged in with another slot 51422 is provided at the bottom of the barrel 5142, and an embedded double-layer grid 51425 is clamped inside the slot 51422, and the embedded double-layer An easy-to-detach buckle 51427 is fixed to the top of one side of the bottom of the grid 51425, and the easy-to-detach buckle 51427 is gap-matched with one side of the top of the embedded double-layer grid 51425. A latch tooth 51426 is provided on the side of the embedded double-layer grid 51425, and the latch tooth 51426 is horizontally arranged on one side of the bottom. An inner groove 51423 matching the latch tooth 51426 is provided on the inner side of the bottom of the slot 51422, and the elastic latch plate 5144 is movably connected to the inside of the slide groove 51421.

[0083] According to the above structure, the installation method of the filter cartridge 514 is as follows:

[0084] After the top of the filter cartridge 514 is fixed to the air pipe 511, the elastic clamping plate 5144 and the magnetic strip 5143 are separated from the outside of the mounting slide 5141, and then the slide groove 51421 is clamped on the outside of the clamping strip 5145, and the other side of the cartridge 5142 is further aligned with the inside of the mounting slide 5141, and then the magnetic strip 5143, the elastic clamping plate 5144 and the outside of the mounting slide 5141 are naturally fitted together, and after the fitting is completed, the elastic clamping plate 5144 is elastic and is squeezed and installed. The barrel 5142 is installed inside the slide groove 51421, and then the installed barrel 5142 is pushed upward, and multiple barrels 5142 are installed one by one inside the installation slide 5141. After the last barrel 5142 is installed, the torsion ring 5148 is rotated to make the internal threaded gear 5151 squeeze the screw 5150 upward, so that the top pressure ring 5149 is pushed upward, and the spring 5152 is used to extrude it upward, so that the multiple barrels 5142 are extruded and fixed.

[0085] When assembling a single barrel 5142, please refer to Fig.12 :

[0086] The installation method is as follows: the activated carbon is loaded into the barrel 5142, and the embedded double-layer grid 51425 is squeezed and installed in the inner slot 51423, and the embedded double-layer grid 51425 is positioned by the engagement between the latch teeth 51426 and the inner slot 51423. The embedded double-layer grid 51425 is double-layered, and an easy-to-detach buckle 51427 is fixed inside the middle of the embedded double-layer grid 51425. After the assembly of multiple barrels 5142, the convex plug-in net 51424 squeezes the top of the easy-to-detach buckle 51427, so that the latch teeth 51426 and the inner slot 51423 are more firmly engaged, so that the embedded double-layer grid 51425 can be installed more stably.

[0087] When the activated carbon inside the barrel 5142 needs to be taken out and replaced, the easily removable buckle 51427 is lifted upwards, and the latching teeth 51426 and the inner slot 51423 are gradually separated from the bottom to the top, and the embedded double-layer grid 51425 can be easily taken out, and the activated carbon can be further poured out and replaced.

[0088] When multiple assembled barrels 5142 are used, they are sucked by the negative pressure fan 510, so that the barrels 5142 from top to bottom absorb different amounts of toxic and harmful gas substances. In addition, the activated carbon inside the top barrel 5142, which first absorbs toxic and harmful substances, has a higher saturation and needs to be replaced in time. The bottom barrel 5142 is pushed upward and a new barrel 5142 is installed at the bottom, so that the activated carbon inside the barrel 5142 can be fully utilized. The top barrel 5142 that has been installed and used is removed, and the removal method is as follows:

[0089] The elastic clamping plate 5144 is forcibly separated from the inside of the slide 51421, and the magnetic strip 5143 that is magnetically attracted to the mounting slide 5141 is gradually separated, and then the barrel 5142 is taken out. During the removal process, the opening side of the slide 51421 and the side of the clamping strip 5145 have a certain elasticity, so as to avoid damaging the slide 51421 and the clamping strip 5145 when separating. The activated carbon can be replaced by pushing the bottom barrel 5142 upwards and installing a new barrel 5142.

[0090] Also, please refer to Figure 5 Combined with Fig. 9 , the working principle of filter cartridge 514 is:

[0091] The toxic and harmful gases are sucked out through the negative pressure fan 510, first through the air inlet 515, and gradually transported to the negative pressure fan 510 through the air pipe 511. When high temperature is generated inside the bucket elevator 5, the memory baffle 512 is turned over, so that the negative pressure port 513 is exposed, and the toxic and harmful gases inside the bucket elevator 5 are sucked out through the negative pressure port 513, and gradually purified and absorbed by the filter cartridge 514, and discharged through the negative pressure fan 510. The air inlet 515 can realize the air inlet and outlet of the working space. Suction is performed and the air is purified through the filter cartridge 514, so that when no toxic or harmful gases are generated inside the bucket elevator 5, the inside of the working space can be purified. The thickness and length of the air pipe 511, the cooling pipe 509 and the filter cartridge 514 shown in the accompanying drawings need to be determined according to the actual space that needs to be purified, and are further adapted to the production line for conveying rubber production. The air pipe 511 at the bottom of the filter cartridge 514 extends to the negative pressure fan 510, and the purified gas is discharged to the outside of the production space or further purified through the negative pressure fan 510.

[0092] The working principle of the open mill 6 is to squeeze and compress the rubber mix through rollers to reduce its volume and increase its density. The roller surface is designed with raised patterns, so that the rubber mix is ​​subjected to greater squeezing force in the area in contact with the roller, so that the rubber materials are more closely combined. At the same time, the open mill can also control the thickness and hardness of the rubber mix by adjusting the speed and pressure of the roller.

[0093] In addition to the cutting and shaping functions, the mixing mill can also be used to remove bubbles and impurities in the mixed rubber to improve product quality. In addition, the mixing mill 6 can also change the properties of the mixed rubber by heating and cooling, such as adjusting hardness and ductility.

[0094] Subsequently, the sheet is coated with a release agent and cooled by a glue cooling machine 7, and the glue cooling machine 7 includes a cooling water tank and a water pump, a radiator, a cooling tower, a control system, a pump station, pipes and connectors.

[0095] The rubber cooling machine 7 is used to cool and solidify the rubber mix for further processing or molding.

[0096] Its working principle is: by sending the mixed rubber from the bucket elevator into the rubber cooler, the temperature of the mixed rubber is rapidly reduced through the action of the cooling water tank and water pump, so that it is solidified into the required shape and size.

[0097] The function of the rubber cooler 7 is to cool and solidify the rubber mix to achieve the required hardness and strength after the mixing process is completed. At the same time, the rubber cooler can also remove bubbles and impurities in the rubber mix to improve product quality. In addition, the rubber cooler can also control the solidification speed and effect of the rubber mix by adjusting the temperature and flow of the cooling water.

[0098] The working principle of the rubber cooler 7 is to transport hot water to the rubber cooler through a cooling water tank and a water pump, and then spray the hot water evenly on the surface of the rubber mix through a sprayer. After the rubber mix contacts the cooling water, the temperature drops rapidly until it reaches the curing temperature. At this point, the cured rubber mix will be sent to the next step for processing or molding.

[0099] In addition, a knife roller and a scraper for processing materials are provided on the roller of the mixing mill 6. The knife roller is used to cut or carve patterns on the mixed rubber, and the scraper is used to scrape off the mixed rubber attached to the roller.

[0100] The control system includes PLC controller, display device, hydraulic system, electrical system, heating system, cooling system, conveying system and detection system. The control system is used to control the operation of the rubber mixing production line, thereby achieving automation.

[0101] Existing compounding production lines such as Figure 2 , the formula materials, such as raw rubber, oil, and various powders such as carbon black, put into the pressure kneading machine 11 for mixing, need to be assisted by the operator offline, weigh the formula weight and pack it into small bags, and then the operator manually feeds the materials. In addition, the pressure kneading machine 11 has low working performance and a harsh environment. The operator needs to wear protective equipment to work, which makes it inconvenient to move during work and the inside of the protective clothing is hot. In addition, the rubber cooling machine 241 is only suitable for the production of thick films and lacks flexibility. In particular, professional rubber mixing companies need to meet the personalized needs of different customers, and both thick and thin films must be able to be produced.

[0102] Compared with the prior art, the present application automatically weighs and delivers the required formula materials of the falling internal mixer 3 through the upper auxiliary machine part composed of the raw rubber online weighing device 1, the oil weighing device, the conveying device 1 2, the falling internal mixer 3, the powder weighing device, and the conveying device 2 4, and then performs closed mixing. The automation degree is high and the workshop environment is clean. In addition, the rubber cooling machine 7 adopts a mesh belt flat-laying structure with strong cooling capacity, which is also suitable for the production of ultra-thin rubber sheets.

[0103] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
