Description

Technical Field

[0001] The utility model relates to the technical field of rubber product mixing and processing, in particular to a rubber product mixing device. Background Art

[0002] Rubber products refer to various products made from rubber as the main raw material through mixing, vulcanization and other processes. Due to its excellent elasticity and wear resistance, rubber is widely used in tires, seals, shock absorbers, hoses, tapes and other fields. Rubber mixing is a key step in the rubber manufacturing process. It mainly involves mixing rubber materials with compounding agents (such as carbon black, oil, sulfur, etc.) in a certain proportion to prepare a rubber formula with specific physical and chemical properties. The quality of rubber products depends to a large extent on the performance of the mixing process and mixing equipment.

[0003] The existing rubber product mixing device still has certain defects and shortcomings in actual use. When the rubber raw materials and compounding agents (such as carbon black, oil, sulfur, etc.) are mixed in the mixing barrel, some harmful gases will be generated after the rubber raw materials and compounding agents are heated and melted, mainly including: benzene, hydrogen sulfide, carbon monoxide and volatile organic compounds (VOCs), etc. When the gas is deflated and the pressure is discharged, the harmful gases will be scattered in the working area and easily inhaled by the staff to cause harm. At the same time, after the mixing is completed, in order to facilitate the next use, the inner wall of the mixing barrel and the stirring rod need to be cleaned in time. However, the existing cleaning mostly adopts manual cleaning, which reduces the production efficiency.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example

[0027] like Figure 1-Figure 8 As shown, a rubber product mixing device comprises: a mixing barrel 1, a feed hopper 101 installed on one side of the top of the mixing barrel 1, a hopper cover 102 rotatably connected to the top of the feed hopper 101 through a hinge, a partition 103 installed on the top of the inside of the mixing barrel 1, a plurality of stirring rods 104 arranged inside the mixing barrel 1, a heating cover 2 fixed to the outside of the mixing barrel 1, a deodorizing component arranged on one side of the top of the mixing barrel 1, used for deodorizing and purifying odors generated by mixing in the mixing barrel 1, and a cleaning component arranged on one side of the top of the mixing barrel 1, used for cleaning the inside of the mixing barrel 1.

[0028] Among them, forward and reverse motors 105 are respectively installed on both sides of the bottom of the mixing barrel 1, and a motor shaft 106 is installed on the top of the forward and reverse motor 105. The motor shaft 106 passes through the inside of the mixing barrel 1 and is connected to multiple stirring rods 104. A discharge pipe 107 is installed at the bottom of the mixing barrel 1, and a solenoid valve a108 is installed on the discharge pipe 107. Multiple circular heating rods 201 are installed inside the heating cover 2, and a temperature controller 202 is installed on one side of the bottom of the circular heating rod 201.

[0029] When the rubber is mixed, the hopper cover 102 on the top of the feed hopper 101 is turned over and opened, and the rubber raw materials and compounding agents are added from the feed hopper 101 into the mixing barrel 1. Since forward and reverse motors 105 are installed on both sides of the bottom of the mixing barrel 1, one forward and reverse motor 105 is started to rotate forward, and the other forward and reverse motor 105 is reversed. The driving motor shaft 106 drives the multiple stirring rods 104 to stir the rubber raw materials and compounding agents in the mixing barrel 1 in a forward and reverse manner, and then the multiple round heating rods 201 in the heating cover 2 are started to heat the mixing barrel 1, and the heat generated by the work is transferred to the mixing barrel 1. Inside the barrel 1, the rubber raw material and the compounding agent are heated and melted, and the stirring rod 104 is stirred forward and backward to make the rubber raw material and the compounding agent mixed evenly. A thermostat 202 is installed on one side of the bottom of the circular heating rod 201. The heating temperature can be set by the thermostat 202. The required heating temperature is adjusted to the required heating temperature according to the mixing requirements. After the rubber raw material and the compounding agent are mixed, the solenoid valve a108 is started to open, and a collection container is placed at the bottom of the discharge pipe 107. The mixed rubber solution is discharged to the collection container through the discharge pipe 107 so that the rubber solution can be used for the next step of processing.

[0030] Among them, the model of the thermostat 202 can be KSD301 jump type thermostat 202, and the working principle is: a temperature sensor is installed inside the thermostat, usually a thermistor (such as NTC thermistor) or a thermocouple, which can sense the temperature of the current environment. The temperature sensor converts the detected temperature value into an electrical signal and sends it to the control unit. A temperature setting value is preset in the control unit. It will compare the real-time temperature with the set temperature. According to the comparison result, the control unit will send a signal to the actuator, such as a relay, a transistor, etc. These actuators are responsible for turning on or off the heater. The thermostat 202 is a mature conventional technology in this technical field, and this scheme does not make improvements to the circuit or program of the thermostat 202. The circuit and signal connection method between the thermostat 202 and the control chassis 6 also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0031] Among them, the deodorization component includes: an air pump 3 installed on one side of the top of the partition 103, an air suction pipe 301 is provided at one end of the air pump 3 and passes through the partition 103, a fine mesh is provided at one end of the air suction pipe 301, an exhaust pipe 302 is installed at the other end of the air pump 3, the exhaust pipe 302 passes through the outside of the mixing barrel 1, an air cleaning cylinder 303 is installed at the outer end of the exhaust pipe 302, an activated carbon plate 304 is installed on one side of the inside of the air cleaning cylinder 303, a negative oxygen ion generator 305 is installed on one side of the activated carbon plate 304, a photocatalyst reactor 306 is installed on one side of the negative oxygen ion generator 305, and a support frame 307 is installed between the air cleaning cylinder 303 and the heating cover 2.

[0032] When the rubber raw materials and compounding agents are mixed and processed inside the mixing barrel 1, harmful gases will be generated inside the mixing barrel 1 when they are heated. At this time, the vacuum pump 3 is started to generate suction in the vacuum pipe 301, and the inside of the mixing barrel 1 is evacuated to suck out the harmful gases generated inside the mixing barrel 1, and the harmful gases are discharged into the exhaust pipe 302 and the clean air cylinder 303 through the vacuum pump 3. When the harmful gases enter the clean air cylinder 303, the pungent odor in the harmful gases is adsorbed by the activated carbon plate 304, and then discharged into the negative oxygen ion generator 305. The negative oxygen ion generator 305 has a high-voltage generator inside, which will produce A high-intensity voltage is generated. When the voltage reaches a certain level, it will cause a discharge phenomenon between the two electrodes in the generator (usually the positive electrode and the negative electrode). During the discharge process, the molecules in the air will be ionized, which means that they have lost or gained one or more electrons. Usually, the oxygen molecule will lose an electron and become a negative oxygen ion (O2-). The ionized negative oxygen ions will move toward the negative electrode and gather in the process. This will produce a certain concentration of negative oxygen ions, which can purify formaldehyde, benzene, and carbon monoxide harmful gases, and then be discharged into the photocatalyst reactor 306.

[0033] The photocatalyst reactor 306 is mainly composed of a suction fan, a reaction chamber, an electrically controlled photocatalyst material, an ultraviolet lamp and a drain pipe. The suction fan sucks air from the negative oxygen ion generator 305 and sucks the gas into the reaction chamber. The electrically controlled photocatalyst material and the ultraviolet lamp in the reaction chamber work to further process the harmful gas, and volatile organic compounds (VOCs), hydrogen sulfide, TVOC and other toxic and harmful gases, pollutants, odors, bacteria, etc. are oxidized and decomposed into harmless CO2 and H2O. The purified gas is discharged from the outer end of the clean air cylinder 303, and the decomposed H2O can be discharged from the drain pipe to prevent the harmful gas from spreading in the working environment and avoiding being inhaled by the staff to cause harm.

[0034] Among them, the model of the negative oxygen ion generator 305 can be JMH-DC12F8K, and the working principle is: there is a high-voltage generator inside the negative oxygen ion generator 305, which will generate a high-intensity voltage. When the voltage reaches a certain level, it will cause a discharge phenomenon between the two electrodes (usually the positive electrode and the negative electrode) in the generator. During the discharge process, the molecules in the air will be ionized, which means that they have lost or gained one or more electrons. Usually, the oxygen molecule will lose an electron and become a negative oxygen ion (O2-). The ionized negative oxygen ions will move toward the negative electrode and gather in this process, so that a certain concentration of negative oxygen ions will be generated, thereby achieving the purpose of improving the air quality. The negative oxygen ion generator 305 is a mature conventional technology in the field of this technology, and this scheme does not improve the circuit or program of the negative oxygen ion generator 305. The circuit and signal connection method between the negative oxygen ion generator 305 and the control chassis 6 also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0035] Among them, the cleaning component includes: a water tank 4 installed on one side of the top of the mixing barrel 1, a water pump 401 installed on one side of the bottom of the water tank 4, a heat-resistant rubber hose 402 installed on the outer end of the water pump 401, a support rod 403 installed in the middle of the mixing barrel 1, a fixed block 404 installed on the top of the support rod 403, micro-electric push rods 405 are respectively installed on both sides of the bottom of the fixed block 404, a cleaning head 406 is sleeved on the support rod 403 and connected to the micro-electric push rod 405, a plurality of spray holes 407 are provided on the outer surface of the cleaning head 406, and an active hole 408 is opened in the middle of the top of the mixing barrel 1 and the partition 103, and the support rod 403 and the cleaning head 406 are located inside the active hole 408.

[0036] After the rubber product is mixed inside the mixing barrel 1, all the mixed rubber solution is discharged from the outside of the mixing barrel 1 for collection. At this time, the water pump 401 and the micro electric push rod 405 are started to work. The water pump 401 draws out the water in the water tank 4 and transports it to the cleaning head 406 through the heat-resistant rubber hose 402. The micro electric push rod 405 pushes the cleaning head 406 to move downward at the support rod 403 and enters the mixing barrel 1 from the movable hole 408. The water transported to the cleaning head 406 is sprayed out from the spray hole 407. Since the cleaning head 406 is arranged in a circular structure and a plurality of spray holes 407 are arranged on the outer surface of the cleaning head 406, the sprayed water The inner periphery of the mixing barrel 1 and the stirring rod 104 can be cleaned, and the mixing barrel 1 can be heated by multiple circular heating rods 201 inside the heating cover 2, so that the sprayed water can be heated into hot water, and the raw materials adhering to the inner wall of the mixing barrel 1 and the stirring rod 104 can be quickly cleaned, and the cleaning waste water is discharged from the discharge pipe 107. The cleaning head 406 is pushed up and down at the support rod 403 by the micro electric push rod 405, and different positions of the inner wall of the mixing barrel 1 and the stirring rod 104 can be cleaned, thereby accelerating the cleaning speed of the mixing barrel 1, thereby improving the production efficiency, and the mixing barrel 1 is cleaned in time after use to avoid increasing the difficulty of later cleaning.

[0037] After the cleaning of the inside of the mixing barrel 1 is completed, the cleaning head 406 is driven by the micro electric push rod 405 to move out of the mixing barrel 1 from the movable hole 408 and return to the original position to avoid affecting the normal use of the mixing barrel 1.

[0038] Among them, a water inlet pipe 5 is installed on one side of the top of the water storage tank 4, a solenoid valve b501 is installed on the water inlet pipe 5, and a connecting head 502 is installed at the bottom of the water inlet pipe 5.

[0039] After the water inside the water tank 4 is used up, the external water supply pipe is connected to the connector 502 and fixed to the water inlet pipe 5, and the solenoid valve b501 is started to open, so that the external water supply pipe transports water to the water inlet pipe 5 and flows into the water tank 4 for storage and standby.

[0040] Among them, fixing rods 409 are installed on both sides of the bottom of the cleaning head 406, and a cleaning head 410 is installed at the bottom of the fixing rod 409, and the cleaning head 410 is sleeved on the support rod 403.

[0041] When the micro electric push rod 405 pushes the cleaning head 406 from the movable hole 408 into the mixing barrel 1, the fixed rod 409 at the bottom of the cleaning head 406 drives the cleaning head 410 to move downward, so that the cleaning head 410 slides on the support rod 403, and cleans the raw materials adhered to the support rod 403, ensuring that the cleaning head 406 can be smoothly moved to the inside of the mixing barrel 1 for cleaning.
