Its function is to mix and plasticize the uniformly mixed raw materials to provide uniform rubber materials for plastic and rubber products used in subsequent production lines. The most important component of the open mixing mill is two relatively rotating mixing rollers with adjustable relative distance. The rubber refining process mainly relies on the two mixing rollers to produce extrusion and shearing effects on the rubber materials. After multiple kneading by the mixing rollers and the chemical reactions accompanying the kneading process, the macromolecular chains inside the rubber are broken, so that the various components in the formula are mixed evenly, and finally the purpose of rubber refining is achieved.

[0015] A method for controlling a rubber swing device of a rubber recovery type mixing mill comprises the following steps:

[0016] The open mill assembly is used to heat and roll the rubber compound and perform preliminary mixing of the blank;

[0017] The blanks in the mixing process are processed in sections by using the cutting assembly to form rubber strips of the same specifications and then enter the mixing mill assembly again for mixing;

[0018] When the rubber strips are mixed and processed without color difference, during the process of the rubber strips entering the pressing assembly for pressing and positioning, two sets of swinging rubber assemblies are used to repeatedly press and shape the rubber strips;

[0019] The rubber strip is removed through the inclined top surface of the cutting assembly;

[0020] The cut rubber material is transferred to the mixing mill component through the cutting component for recycling;

[0021] During the process of evenly distributing the rubber material through the mixing mill components and continuously mixing, two sets of rubber swing components are started to move at the same level;

[0022] When the rubber material has no more recycling treatment, the movement of the two sets of swing rubber components is stopped.

[0023] The beneficial effects of the present invention are:

[0024] 1. The mixing mill assembly is used to heat and roll the rubber material, and the blank material is preliminarily mixed. The cutting assembly is used to segment the blank material in the mixing process to form rubber strips of the same specification and enter the mixing mill assembly again for mixing. When the rubber strips are mixed and processed without color difference, the rubber strips enter the pressing assembly for pressing and positioning, and the two sets of swing rubber assemblies are used to repeatedly press and shape the rubber strips. The cut rubber material is transferred to the mixing mill assembly through the cutting assembly for recycling. In the process of evenly distributing the rubber material through the mixing mill assembly and continuously refining, the two sets of swing rubber assemblies are started to move at the same level. When the rubber material is not recycled, the movement of the two sets of swing rubber assemblies is stopped.

[0025] 2. The output end of the second motor drives several groups of shredder rods to rotate, so that the rubber material is shredded in the process of entering the recycling box, and negative pressure is generated near the bottom of the feed pipe under the action of the suction pump, so that the shredded rubber material is adsorbed into the discharge pipe and transferred to between the two groups of heated rollers again. At this time, the second electric push rod is used to reciprocate the rubber swing component to sort the rubber material on the surface of the heated roller. If the suction pump cannot adsorb the shredded rubber material in the recycling box, the second electric push rod will no longer reciprocate to push the rubber swing component, so that the rubber material between the two groups of heated rollers can be continuously mixed in a limited space.

[0026] 3. The output end of the third motor drives the active gear to move back and forth, so that the driven gear is meshed with the active gear and the discharge pipe is driven to swing back and forth. During the swinging process of the discharge pipe, the chopped rubber material is dispersed at different positions between the two sets of heated pressure rollers, entering a small cycle of mixing processing, and quickly matching the color of the rubber material to avoid manual operation, reduce the contamination of light-colored rubber material by manual hands, and improve the color quality of the light-colored rubber material.

[0027] 4. After the rubber materials of different colors are mixed and processed by two sets of heated pressure rollers, the small cycle processing is completed, and the worker lifts one end of the cut rubber strip and puts it on the positioning roller. The output end of the third electric push rod drives the pressure roller to press down while pressing the rubber strip. In the process of the fourth motor continuously driving the positioning roller to rotate, the rubber strip is pressed and formed in a large cycle, and the third electric push rod is used to drive the pressure roller to rise and fall to adjust the distance between the pressure roller and the positioning roller, so as to facilitate the processing of rubber strips of different thicknesses.

[0028] 5. The side of the gathering cylinder away from the guide groove is used to limit the operator's hands from being inserted when the heated pressure roller is working. After the cold air is injected into the cold air input hole, the gathering cylinder is rotated to rotate the guide groove to the top surface of the inclined table, so that the cold air blows from the guide groove at an inclined angle to the top surface of the inclined table, which is used to prevent the adhesive from sticking to the inclined table due to excessive temperature. In addition, the top surface of the inclined table can also speed up the speed at which the block adhesive falls into the recovery box under the action of the cold air.

[0046] The mixing mill assembly 1 includes a housing 11; illustratively, Figure 3 and Figure 4 shown.

[0047] The cross section of the shell 11 is a concave structure, and two groups of first electric push rods 12 are embedded and installed at the bottom end of the inner wall of the shell 11, and two groups of heated pressure rollers 13 are rotatably connected to the inner wall of the shell 11. A first motor 14 is fixedly connected to the outer wall of the shell 11, and the output end of the first motor 14 is transmission-connected to the heated pressure roller 13. A plurality of groups of second electric push rods 15 are embedded and installed on the inner wall of the shell 11, and the output ends of the plurality of second electric push rods 15 are transmission-connected to the swing rubber assembly 4, and the swing rubber assembly 4 is slidably fitted and connected to the outer wall of the heated pressure roller 13. Both sides of the inner wall of the shell 11 and the bottom of the heated pressure roller 13 are provided with embedded grooves 16, and the embedded grooves 16 are arranged in an inclined shape;

[0048] A recycling box 17 is fixedly connected to one side of the outer wall of the shell 11, and a plurality of groups of second motors 18 are fixedly connected to the outer wall of the recycling box 17 and the side away from the shell 11, and the plurality of groups of second motors 18 are arranged at the same level. A plurality of groups of crushing rods 19 are rotatably connected to the inner wall of the recycling box 17, and one end of the plurality of groups of crushing rods 19 are transmission-connected to the output end of the second motor 18. A transverse plate 110 is fixedly connected to the outer wall of the shell 11 and located at the top of the recycling box 17. A feeding pipe 111 is embedded in the outer wall of the transverse plate 110, and the bottom end of the feeding pipe 111 extends into the recycling box 17. A third motor 112 is fixedly connected to the bottom of the plate 110, and the output end of the third motor 112 is transmission-connected to a driving tooth 113, and the top of the horizontal plate 110 is rotatably connected to a driven tooth 116, and a discharge pipe 114 is embedded and installed at the center of the central axis of the driven tooth 116, and a discharge sensor is provided at the end of the discharge pipe 114, one end of the discharge pipe 114 is communicated with the feed pipe 111, and the discharge pipe 114 is U-shaped, a suction pump 115 is provided on the discharge pipe 114, and the end of the discharge pipe 114 away from the driven tooth 116 extends to the top between the two groups of heated pressure rollers 13.

[0049] Furthermore, a controller is disposed on the outer wall of the housing 11 , and the controller is electrically connected to the discharge sensor and the second electric push rod 15 .

[0050] Specifically, the rubber blank is stored between the two groups of heating rollers 13, and the heating rollers 13 are driven to rotate under the action of the first motor 14, so that the rubber blank is heated and rolled, and the rubber falling between the two groups of heating rollers 13 falls into the recovery box 17;

[0051] The output end of the second motor 18 drives a plurality of groups of shredder rods 19 to rotate, so that the rubber material is shredded in the process of entering the recovery box 17, and a negative pressure is generated near the bottom of the feed pipe 111 under the action of the suction pump 115, so that the shredded rubber material is adsorbed into the discharge pipe 114 and transferred to between the two groups of heated pressure rollers 13 again. At this moment, the second electric push rod 15 is used to reciprocate and push the swing rubber component 4 to sort the rubber material on the surface of the heated pressure roller 13. If the suction pump 115 cannot adsorb the shredded rubber material in the recovery box 17, the second electric push rod 15 will no longer reciprocate and push the swing rubber component 4, so that the rubber material between the two groups of heated pressure rollers 13 is continuously mixed and processed in a limited space;

[0052] The output end of the third motor 112 drives the active teeth 113 to move back and forth, so that the driven teeth 116 are meshed and connected with the active teeth 113, and at the same time, drives the discharge pipe 114 to swing back and forth, so that the discharge pipe 114 can disperse the chopped rubber material at different positions between the two groups of heated pressure rollers 13 during the swinging process, enter a small cycle mixing processing state, quickly proportion the color of the rubber material, avoid manual operation, reduce the contamination of light-colored rubber material by human hands, and improve the color quality of the light-colored rubber material.

[0053] The discharging sensor is used to detect the discharging amount of the discharging pipe 114. If the discharging sensor fails to detect the discharging state, the discharging sensor transmits a signal to the controller, and after analysis, the controller controls the second electric push rod 15 to stop working.

[0054] The pressing assembly 2 includes two sets of positioning plates 21; illustratively, as Figure 5 shown.

[0055] A positioning roller 22 is rotatably connected between the two groups of positioning plates 21, and the bottoms of the two groups of positioning plates 21 are fixedly connected to the top of the shell 11, a fourth motor 23 is fixedly connected to the outer wall of one group of positioning plates 21, and the output ends of the fourth motor 23 are transmission connected to the positioning roller 22, and a pressing roller 24 is movably and closely connected to the top of the positioning roller 22, and both ends of the pressing roller 24 are rotatably connected to a linkage arm 26, and the other end of the linkage arm 26 is fixedly connected to the top of the shell 11, and both ends of the pressing roller 24 are transmission connected to the output ends of the third electric push rod 25.

[0056] Specifically, after the two groups of heated pressing rollers 13 mix and process the rubber materials of different colors, the small cycle processing is completed, and the worker lifts one end of the cut rubber strip and puts it onto the positioning roller 22. The output end of the third electric push rod 25 drives the pressing roller 24 to press down while pressing the rubber strip. In the process of the fourth motor 23 continuously driving the positioning roller 22 to rotate, the rubber strip is pressed and formed in a large cycle, and the third electric push rod 25 is used to drive the pressing roller 24 to rise and fall, so as to adjust the distance between the pressing roller 24 and the positioning roller 22, so as to facilitate the processing of rubber strips of different thicknesses.

[0057] The cutting assembly 3 includes a bevel table 31; illustratively, as Figure 6 , Figure 7 and Figure 8 shown.

[0058] The top of the inclined platform 31 is slidably connected with two groups of splicing plates 32, and the two groups of splicing plates 32 are slidably connected in the embedded groove 16. The top of the inclined platform 31 is provided with a slide groove 33, and the side wall of the inclined platform 31 is provided with a first slide cavity 34 that is interconnected with the slide groove 33. A linkage housing 35 is slidably connected in the slide groove 33, and a side wall of the linkage housing 35 close to the first slide cavity 34 is provided with a second slide cavity 36. The bottom end of the inner wall of the linkage housing 35 is movably connected. There are several groups of fourth electric push rods 37, and the output ends of several groups of the fourth electric push rods 37 are all transmission-connected with blades 38. One side wall of several groups of the fourth electric push rods 37 is provided with a self-locking rod 39, and the self-locking rod 39 passes through the second sliding cavity 36 and the first sliding cavity 34.

[0059] Specifically, when the two groups of splicing plates 32 are slidably connected in the embedded groove 16, they are in a stored state. When the two groups of splicing plates 32 slide out of the embedded groove 16, they are used to block the linkage housing 35 and the recovery box 17, so as to facilitate the unloading of the rubber strip after the large circulation;

[0060] The output ends of several groups of the fourth electric push rods 37 push the blades 38 up, so that the blades 38 move to the bottom of the heated pressure roller 13 at the same level. When the rubber on the heated pressure roller 13 is close to the blades 38, the rubber is cut at equal intervals, and the self-locking rod 39 is pulled laterally to adjust the spacing of each group of blades 38, and then each group of blades 38 is locked by the screws 310, so that the blades 38 can cut the rubber stably.

[0063] Specifically, the connection between the two groups of swing rubber rings 41 is used to clean the gap between the two groups of heated pressure rollers 13 to remove the rubber. In the process of the second electric push rod 15 pushing the two groups of swing rubber rings 41 closer to each other, the rubber remaining on the heated pressure roller 13 is gathered to make the mixing of the rubber more efficient during the small circulation process. The servo motor is used to drive the feeding rod 43 to rotate, so that the mixed rubber can efficiently enter between the positioning roller 22 and the pressing roller 24 during the large circulation process, so as to be used for the rapid molding of the rubber strip.

[0064] The unloading and anti-sticking assembly 5 includes a gathering cylinder 51; illustratively, as Figure 2 shown.

[0065] A guide groove 52 is provided on one side wall of the gathering cylinder 51, and the length of the guide groove 52 is the same as the length of the swing rubber component 4. Both ends of the gathering cylinder 51 are rotatably connected with bearings 53. A cold air input hole 54 is provided at one end of the gathering cylinder 51. Positioning seats 55 are provided on the tops of the two groups of bearings 53. A linkage seat 56 is provided on the tops of the positioning seats 55. A fifth electric push rod is embedded in the bottom of the linkage seat 56, and the output ends of the fifth electric push rod are transmission-connected with the top of the positioning seat 55. The tops of the two groups of linkage seats 56 are rotatably connected with hinge seats 57, and the other ends of the hinge seats 57 are fixedly connected to the outer wall of the shell 11.

[0066] Specifically, the gathering cylinder 51 is located away from the side of the guide groove 52, which is used to limit the operator from putting his hands into the heated pressure roller 13 when it is working. After injecting cold air into the cold air input hole 54, the gathering cylinder 51 is rotated to rotate the guide groove 52 to the top surface of the inclined table 31, so that the cold air blows from the guide groove 52 at an inclined angle to the top surface of the inclined table 31, which is used to prevent the adhesive from sticking to the inclined table 31 due to excessive temperature. Under the action of the cold air, the top surface of the inclined table 31 can also speed up the speed at which the block adhesive falls into the recovery box 17.

[0067] The working principle of the rubber swing device of the rubber recovery type mixing mill proposed by the embodiment of the present invention is as follows:

[0068] The rubber blank is stored between two sets of heated rollers 13, and the heated rollers 13 are driven to rotate by the first motor 14 to heat and press the rubber blank, and the rubber blank dropped between the two sets of heated rollers 13 drops into the recovery box 17;

[0069] The output end of the second motor 18 drives a plurality of groups of shredder rods 19 to rotate, so that the rubber material is shredded in the process of entering the recovery box 17, and a negative pressure is generated near the bottom of the feed pipe 111 under the action of the suction pump 115, so that the shredded rubber material is adsorbed into the discharge pipe 114 and transferred to between the two groups of heated pressure rollers 13 again. At this moment, the second electric push rod 15 is used to reciprocate and push the swing rubber component 4 to sort the rubber material on the surface of the heated pressure roller 13. If the suction pump 115 cannot adsorb the shredded rubber material in the recovery box 17, the second electric push rod 15 will no longer reciprocate and push the swing rubber component 4, so that the rubber material between the two groups of heated pressure rollers 13 is continuously mixed and processed in a limited space;

[0070] The output end of the third motor 112 drives the active gear 113 to move back and forth, so that the driven gear 116 is meshed and connected with the active gear 113, and at the same time, drives the discharge pipe 114 to swing back and forth, so that the discharge pipe 114 disperses the chopped rubber material at different positions between the two groups of heated pressure rollers 13 during the swinging process, enters a small cycle mixing processing state, and quickly proportions the color of the rubber material, avoiding manual operation, reducing the contamination of light-colored rubber material by manual hands, and improving the color quality of the light-colored rubber material;

[0071] After the rubber materials of different colors are mixed and processed by two sets of heated pressing rollers 13, the small cycle processing is completed, and the worker lifts one end of the cut rubber strip and puts it on the positioning roller 22. The output end of the third electric push rod 25 drives the pressing roller 24 to press down and press the rubber strip. In the process of the fourth motor 23 continuously driving the positioning roller 22 to rotate, the rubber strip is pressed and formed in a large cycle, and the third electric push rod 25 is used to drive the pressing roller 24 to rise and fall, which is used to adjust the distance between the pressing roller 24 and the positioning roller 22, so as to facilitate the processing of rubber strips of different thicknesses;

[0072] When the splicing plates 32 are slidably connected in the embedded groove 16, they are in a stored state. When the two sets of splicing plates 32 slide out of the embedded groove 16, they are used to block the linkage housing 35 and the recovery box 17, so as to facilitate the unloading of the rubber strip after the large circulation;

[0073] The blades 38 are pushed upward by the output ends of the plurality of fourth electric push rods 37, so that the blades 38 are moved to the bottom of the heated pressure roller 13 at the same level. When the rubber material on the heated pressure roller 13 is close to the blades 38, the rubber material is cut at equal intervals, and the self-locking rod 39 is pulled laterally to adjust the interval of each set of blades 38, and then each set of blades 38 is locked by the screw 310, so that the blades 38 can stably cut the rubber material;

[0074] The connection between the two sets of swing rubber rings 41 is used to clean the gap between the two sets of swing rubber rings 41 to remove the rubber. In the process of the second electric push rod 15 pushing the two sets of swing rubber rings 41 closer to each other, the rubber remaining on the heated pressing roller 13 is gathered to make the mixing of the rubber more efficient during the small circulation process. The servo motor is used to drive the feeding rod 43 to rotate, so that the mixed rubber can efficiently enter between the positioning roller 22 and the pressing roller 24 during the large circulation process, so as to be used for the rapid molding of the rubber strip.

[0075] The side of the gathering cylinder 51 away from the guide groove 52 is used to limit the operator's hands from being inserted into the heated pressure roller 13 when it is working. After the cold air is injected into the cold air input hole 54, the gathering cylinder 51 is rotated to rotate the guide groove 52 to the top surface of the inclined table 31, so that the cold air blows from the guide groove 52 at an inclined angle to the top surface of the inclined table 31, which is used to prevent the adhesive from sticking to the inclined table 31 due to the high temperature. In addition, the top surface of the inclined table 31 can also accelerate the speed at which the block adhesive falls into the recovery box 17 under the action of the cold air.

[0076] Based on the above-mentioned rubber swing device of a rubber recovery type mixing mill, an embodiment of the present invention further provides a method for controlling the rubber swing device of a rubber recovery type mixing mill, comprising the following steps:

[0077] The open mill assembly is used to heat and roll the rubber compound and perform preliminary mixing of the blank;

[0078] The blanks in the mixing process are processed in sections by using the cutting assembly to form rubber strips of the same specifications and then enter the mixing mill assembly again for mixing;

[0079] When the rubber strips are mixed and processed without color difference, during the process of the rubber strips entering the pressing assembly for pressing and positioning, two sets of swinging rubber assemblies are used to repeatedly press and shape the rubber strips;

[0080] The rubber strip is removed through the inclined top surface of the cutting assembly;

[0081] The cut rubber material is transferred to the mixing mill component through the cutting component for recycling;

[0082] During the process of evenly distributing the rubber material through the mixing mill components and continuously mixing, two sets of rubber swing components are started to move at the same level;

[0083] When the rubber material has no more recycling treatment, the movement of the two sets of swing rubber components is stopped.

[0084] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
