Description

Technical Field

[0001] This invention relates to the field of rubber elastic layer processing technology, specifically to an automatic sulfonation and cleaning device for rubber elastic layers. Background Technology

[0002] The rubber elastic layer refers to a material layer that has rubber properties and can provide good elasticity. It is mainly made of rubber or rubber-like materials. In the processing of the rubber elastic layer, in order to improve the physical and mechanical properties and chemical stability of the rubber, sulfonation and cleaning equipment are generally used to sulfonate the rubber elastic layer and clean it after sulfonation.

[0003] Existing automated sulfonation and cleaning equipment for rubber elastic layers mainly consists of a sulfonation tank, a cold water washing tank, a hot water washing tank, and an ultrasonic cleaning tank. During use, the rubber elastic layer is sulfonated in the sulfonation tank, and then cleaned in the cold water washing tank, hot water washing tank, and ultrasonic cleaning tank. However, after the rubber elastic layer is washed in cold water, its temperature is low. When it is then placed in the hot water washing tank, the rubber elastic layer experiences a significant temperature difference, which may affect its performance and thus the processing effect. Therefore, we propose an automated sulfonation and cleaning equipment for rubber elastic layers. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that after the rubber elastic layer is washed with cold water, its temperature is low. When it is then placed in a hot water washing tank for further cleaning, the rubber elastic layer will be subjected to a large temperature difference, which may affect the performance of the rubber elastic layer and thus easily affect the processing effect of the rubber elastic layer.

[0005] To address the aforementioned technical problems, this application provides an automated sulfonation and cleaning device for rubber elastic layers, comprising a machine body, a shaft robot, a safety door, a safety light curtain, a transfer positioning frame, a sulfonation tank, a cold water washing tank, a hot water washing tank, and an ultrasonic cleaning tank, and further comprising:

[0008] A filter screen is installed on one side of the hot water washing tank and is fixedly connected to the preheating mechanism for filtering airflow.

[0009] A cleaning mechanism is rotatably connected to the outer surface of the hot water washing tank and is used to clean dust particles adhering to the surface of the filter screen.

[0010] In some embodiments, the preheating mechanism includes an air guide shell disposed on the outer surface of the hot water washing tank, the air guide shell being fixedly connected to a filter screen, a heating tube disposed on the inner surface of the air guide shell being fixedly connected to the hot water washing tank, a flexible hose being disposed at one end of the heating tube being fixedly connected to a shaft robot, a connecting shell being disposed at one end of the flexible hose being fixedly connected to the shaft robot, two flexible hoses being disposed on the outer surface of the connecting shell being fixedly connected to the shaft robot, a plurality of nozzles being disposed on the outer surface of the flexible hoses being disposed, an exhaust mechanism being disposed on the inner wall of the air guide shell being fixedly connected to the hot water washing tank, and a sealing mechanism being rotatably connected to the inner surface of the connecting shell.

[0011] In some embodiments, the heating tube is S-shaped.

[0012] In some embodiments, the exhaust mechanism includes a bracket disposed on the inner wall of the air guide shell. A rotating shaft is rotatably connected to the inner surface of the bracket. A fan blade is disposed on the outer surface of the rotating shaft. A bevel gear is disposed on the outer surface of the rotating shaft located on one side of the fan blade. A bevel gear is meshed with the outer surface of the bevel gear. A rotating shaft is disposed on the end face of the bevel gear. The rotating shaft is rotatably connected to the air guide shell and to the hot water washing tank. A motor is disposed on the outer surface of the hot water washing tank. The output end of the motor is fixedly connected to the rotating shaft.

[0013] In some embodiments, the mesh diameter of the filter is 5mm-7mm.

[0014] In some embodiments, the sealing mechanism includes a rotating shaft three rotatably connected to the inner surface of the connecting shell. The outer surface of the rotating shaft three is provided with blades, and a half gear is provided on the outer surface of the rotating shaft three located on one side of the blades. A toothed plate is meshed with the outer surface of the half gear, and two connecting rods are provided on the outer surface of the toothed plate. A sealing plate is provided at one end of each connecting rod, and both sealing plates are slidably connected to the connecting shell. A connecting block is provided on the outer surface of the connecting rod, and a return spring is provided on the outer surface of the connecting block. Both return springs are fixedly connected to the connecting shell.

[0015] In some embodiments, the cleaning mechanism includes a reciprocating screw rotatably connected to the outer surface of the hot water bath, a cleaning plate threadedly connected to the outer surface of the reciprocating screw, a limit rod slidably connected to the inner surface of the cleaning plate, the limit rod being fixedly connected to the hot water bath, and a transmission mechanism provided on the outer surface of the reciprocating screw.

[0016] In some embodiments, the transmission mechanism includes a pulley 1 disposed on the outer surface of a reciprocating lead screw, and a pulley 2 disposed on the outer surface of a rotating shaft 2. The pulley 2 and the pulley 1 are connected by a belt body for transmission.

[0017] In some embodiments, the transmission ratio between pulley one and pulley two is 1:2, and the pitch of the reciprocating lead screw is 0.5mm.

[0018] In some embodiments, the first hose, the connecting shell, and the second hose are all made of polypropylene plastic.

[0019] This invention has at least the following beneficial effects:

[0020] 1. Through the setup of a preheating mechanism, filter, exhaust mechanism, and sealing mechanism, impurities adhering to the surface of the rubber elastic layer after cold water washing can be alternately cleaned by air jets, facilitating subsequent processing of the rubber elastic layer. When the rubber elastic layer is completely separated from the cold water, a gravity sensor detects the weight and transmits a signal. At this time, the motor speed in the exhaust mechanism decreases, reducing the airflow velocity. Then, the elastic force of the return spring in the sealing mechanism keeps the sealing plate stationary. Simultaneously, the nozzles in the preheating mechanism located on both sides of the rubber elastic layer can spray heated airflow. The rubber elastic layer is preheated, and then it is washed with hot water. During this process, the cleaning mechanism and the transmission mechanism work together to remove dust particles adhering to the filter screen surface, ensuring the ventilation effect of the filter screen. Unlike the method of washing the rubber elastic layer with cold water and then directly placing it into the hot water washing tank, the method of cleaning the impurities adhering to the surface of the rubber elastic layer and preheating the rubber elastic layer can effectively avoid the possibility of the rubber elastic layer being affected by large temperature differences, thus ensuring the processing effect of the rubber elastic layer.

[0033] Example 1

[0034] Please see Figure 1-9 The present invention provides a technical solution:

[0035] An automated sulfonation and cleaning device for rubber elastic layers includes a machine body 1, an axis robot 9, a safety door 10, a safety light curtain 11, a transfer positioning frame 12, a sulfonation tank 13, a cold water washing tank 14, a hot water washing tank 15, and an ultrasonic cleaning tank 16, and further includes:

[0036] Gravity sensor 2 is installed on the outer surface of axis robot 9;

[0037] The preheating mechanism 3 is installed on the outer surface of the hot water washing tank 15. The preheating mechanism 3 is fixedly connected to the axis robot 9 and is used for preheating the rubber elastic layer and cleaning impurities attached to the surface of the rubber elastic layer.

[0039] The cleaning mechanism 5 is rotatably connected to the outer surface of the hot water washing tank 15 and is used to clean dust particles adhering to the surface of the filter screen 4.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the preheating mechanism 3 includes an air guide shell 31 disposed on the outer surface of the hot water washing tank 15. The air guide shell 31 is fixedly connected to the filter screen 4. A heating tube 32 is disposed on the inner surface of the air guide shell 31. The heating tube 32 is fixedly connected to the hot water washing tank 15. A flexible hose 33 is disposed at one end of the heating tube 32.

[0041] Specifically, such as Figure 5 As shown, the heating tube 32 is S-shaped, which can increase the length of the heating path in a limited space, thereby increasing the heating area and heating the airflow better.

[0042] Specifically, such as Figure 5 , Figure 6 and Figure 7As shown, the exhaust mechanism 6 includes a bracket 61 disposed on the inner wall of the air guide shell 31. A rotating shaft 62 is rotatably connected to the inner surface of the bracket 61. A fan blade 63 is disposed on the outer surface of the rotating shaft 62. A bevel gear 64 is disposed on the outer surface of the rotating shaft 62 located on one side of the fan blade 63. A bevel gear 65 is meshed with the outer surface of the bevel gear 64. A rotating shaft 66 is disposed on the end face of the bevel gear 65. The rotating shaft 66 is rotatably connected to the air guide shell 31 and to the hot water washing tank 15. A motor 67 is disposed on the outer surface of the hot water washing tank 15. The output end of the motor 67 is fixedly connected to the rotating shaft 66.

[0043] Specifically, such as Figure 5 and Figure 6 As shown, the mesh diameter of filter 4 is 5mm-7mm, which can effectively filter dust particles in the external airflow, while allowing the external airflow to pass through smoothly.

[0044] Specifically, such as Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the sealing mechanism 7 includes a rotating shaft 71 rotatably connected to the inner surface of the connecting shell 34. A blade 72 is provided on the outer surface of the rotating shaft 71. A half gear 73 is provided on the outer surface of the rotating shaft 71 located on one side of the blade 72. A toothed plate 74 is meshed on the outer surface of the half gear 73. Two connecting rods 75 are provided on the outer surface of the toothed plate 74. A sealing plate 76 is provided at one end of the connecting rod 75. Both sealing plates 76 are slidably connected to the connecting shell 34. A connecting block 77 is provided on the outer surface of the connecting rod 75. A return spring 78 is provided on the outer surface of the connecting block 77. Both return springs 78 are fixedly connected to the connecting shell 34.

[0045] Specifically, such as Figure 5 and Figure 6 As shown, the cleaning mechanism 5 includes a reciprocating screw 51 rotatably connected to the outer surface of the hot water washing tank 15. A cleaning plate 52 is threadedly connected to the outer surface of the reciprocating screw 51. A limit rod 53 is slidably connected to the inner surface of the cleaning plate 52. The limit rod 53 is fixedly connected to the hot water washing tank 15. A transmission mechanism 8 is provided on the outer surface of the reciprocating screw 51.

[0046] Specifically, such as Figure 6 As shown, the transmission mechanism 8 includes a pulley 81 disposed on the outer surface of the reciprocating screw 51, and a pulley 82 disposed on the outer surface of the rotating shaft 66. The pulley 82 and the pulley 81 are connected by a belt body 83.

[0047] Specifically, such as Figure 6 As shown, the transmission ratio between pulley 81 and pulley 82 is 1:2, and the pitch of the reciprocating screw 51 is 0.5mm. Under normal ventilation conditions of the fan blade 63, the cleaning plate 52 can move slowly back and forth, reducing friction.

[0048] In use, the rubber elastic layer is sulfonated in the sulfonation tank 13, and then the rubber elastic layer is cleaned in cold water, hot water and ultrasonic in sequence in the cold water washing tank 14, hot water washing tank 15 and ultrasonic cleaning tank 16. During the sulfonation and cleaning process, the rubber elastic layer is gripped and placed by the axis robot 9.

[0049] After the rubber elastic layer is cleaned with cold water, it is placed in the hot water washing tank 15 for hot water cleaning. During this process, motor 67 can be started. The output of motor 67 rotates, driving shaft 2 66 to rotate. Shaft 2 66 then drives bevel gear 2 65 to rotate, which in turn drives bevel gear 1 64 to rotate. Bevel gear 1 64 then drives shaft 1 62 to rotate, which in turn drives fan blade 63 to rotate. This allows external airflow to pass through filter 4, air guide shell 31, heating tube 32, hose 1 33, connecting shell 34, and hose 2 35 into nozzle 36. The airflow is then sprayed out through nozzle 36, cleaning impurities adhering to the surface of the rubber elastic layer and preheating the rubber elastic layer. During this process, filter 4 filters dust particles from the airflow. The filtered airflow flows inside heating tube 32 and is heated by hot water in the hot water washing tank 15. When the heated airflow comes into contact with blade 72, blade 72 rotates. The rotation of blade 72 then drives shaft 3 71 to rotate, which in turn drives half gear 73 to rotate. The machine moves, and then the half gear 73 rotates to drive the toothed plate 74 to move back and forth, which in turn drives the connecting rod 75 to move back and forth. Then, the connecting rod 75 moves back and forth to drive the sealing plate 76 to move back and forth, alternately sealing the air outlet of the connecting shell 34, so that the nozzles 36 on both sides of the rubber elastic layer alternately spray air. At this time, the impurities attached to the surface of the rubber elastic layer will shake, thus cleaning the impurities attached to the surface of the rubber elastic layer. When the rubber elastic layer is completely separated from the cold water by the shaft robot 9, the buoyancy of the rubber elastic layer is released, the gravity sensor 2 detects the value to reach the preset value, and transmits the signal. At this time, the speed of the output end of the motor 67 decreases, so that the airflow speed decreases. Then, through the elastic force of the reset spring 78, the rotating shaft 71, blade 72, half gear 73, toothed plate 74, connecting rod 75, sealing plate 76 and connecting block 77 are in a stationary state. At this time, the heating airflow with reduced speed can be sprayed out through the nozzles 36 on both sides of the rubber elastic layer to preheat the rubber elastic layer that is completely separated from the cold water.

[0050] During the cleaning of impurities adhering to the surface of the rubber elastic layer and the preheating of the rubber elastic layer, the rotation of the second shaft 66 will drive the second pulley 82 to rotate, and then the rotation of the second pulley 82 will drive the first pulley 81 to rotate, which in turn will drive the reciprocating screw 51 to rotate. Then, the rotation of the reciprocating screw 51 will drive the cleaning plate 52 to move up and down slowly to clean the dust particles adhering to the surface of the filter screen 4. During this process, the movement of the cleaning plate 52 is stabilized by the limit rod 53.

[0051] Example 2

[0052] Please see Figure 10 The present invention provides a technical solution:

[0053] Unlike Example 1, the first hose 33, the connecting shell 34, and the second hose 35 are all made of polypropylene plastic.

[0054] The hose 33, connecting shell 34, and hose 35, made of polypropylene plastic, are lightweight, reducing the operational burden on the axis robot 9. They also exhibit high heat resistance, effectively withstanding temperature changes and resisting deformation. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
