Description

Technical Field

[0001] The utility model relates to the production of coumarone resin particles, weight sensing control technology, programmable logic control technology, and specifically relates to a production device for coumarone resin particles that can automatically load materials. Technical Background

[0002] Coumarone resin particles have great economic benefits and are widely used in industries such as rubber, plastics, coatings, adhesives, etc. Traditional coumarone resin particle production machines often use flat steel belts, which occupy a large area in the factory. The particle size of coumarone resin particles between 1 mm and 5 mm has good use performance. However, in the traditional production process of coumarone resin particles, there are no corresponding control measures for the particle size of coumarone resin particles. Therefore, the quality of the obtained coumarone resin is not stable, and the final collection of coumarone resin particles has low automation and strong dependence on manual labor. Content of the Utility Model

[0003] In view of the phenomena of large floor area occupied by traditional coumarone resin particle production machines, unstable quality of resin particles, and strong dependence on manual labor for coumarone resin particles, the utility model designs a production device for coumarone resin particles that can automatically load materials. The steel belt of this production device adopts a spiral expansion, which greatly reduces the floor area under the condition of unchanged steel belt length; a sieve particle opening is designed, which can control the particle size of coumarone resin particles below 5 mm to ensure good use performance of coumarone resin; a weight sensor is involved at the material receiving port, which can automatically weigh. After reaching the set weight, it controls the opening and closing of the discharge port with a signal, reducing the dependence on manual labor for collecting coumarone particles.

[0004] The technical solution of the utility model is: a production device for coumarone resin particles that can automatically load materials, mainly including a feeding machine (ZL-H), a programmable logic controller (FX1S), a spraying device (XBD12.5 / 13.9-80-315), a cooling water pipe (YX-IPX9KB-500L), a grinding machine (BS-10L), a weight sensor (MT1022-3kg), an electric switch (DZ47S 1P16A), a feeding machine, a feeding pipeline, a spiral steel belt channel, a discharge pipeline, a discharge nozzle, a sieve particle grinding machine, a first conveyor belt, a sieve particle opening, a second conveyor belt, and a second discharge port.

[0005] For the described feeding machine (ZH-L), the state of coumarone resin entering the feeding machine is a flowing state. Nozzles are installed inside the feeding machine (ZH-L), which can control the outflow speed, flow rate, and form of the fluid, thereby dividing the continuous fluid into uniform droplets. These droplets form granular products after steps such as solidification and cooling in subsequent process steps.

[0006] The described spiral steel belt through-pass housing and its interior are both made of 304 stainless steel, which is not easily corroded in a humid environment. The steel belt is made of carbon steel, with low cost. The transmission power of the spiral steel belt comes from electricity, and the connected voltage is 220V.

[0007] The described No. 1 conveyor belt and No. 2 conveyor belt are both made of carbon steel, with high strength and hardness and relatively low cost. The transmission power of the conveyor belt comes from electricity, and the connected voltage is 220V.

[0008] The described cooling water pipe (YX-IPX9KB-500L) consists of a nozzle, a pipe system, a pump, and a liquid storage tank. The liquid storage tank stores cooling water. Since the softening point of coumarone resin is 75 - 135°C, the temperature of the cooling water is kept below 75°C to keep the coumarone resin in a solid state. The pump generates power to lift the water from the ground to the height of the spiral steel belt pipe at the top floor and injects it into the pipe. The voltage connected to the pump is 380V.

[0009] The described spraying device (XBD12.5 / 13.9-80-315) consists of a nozzle, a pipe system, a pump, and a control system. The pump generates power to lift the water from the ground to the height of the spiral steel belt pipe at the top floor and injects it into the pipe. The voltage connected to the pump is 380V. The spraying device is connected to the bottom of the spiral steel belt pipe. The cooling water is input at the highest point of the spiral steel belt pipe by the cooling water pipe. While cooling the coumarone resin, due to the factor of gravity, it flows downward and into the pipe system of the spraying device. This method can reuse water resources and achieve the effect of water conservation; through the power lift of the pump, the water is sprayed at the bottom of the spiral steel belt, playing a role in cooling the coumarone resin. Spraying cooling can spray the water more evenly and has a better cooling effect.

[0010] The described sieve-granule grinder is divided into upper and lower layers. There is a sieve-granule opening on the first conveyor belt in the upper layer, with a diameter of 5mm, which can screen out the coumarone resin with excellent performance and a size smaller than 5mm and let it fall onto the second conveyor belt. The second conveyor belt transports this coumarone resin to the second discharge port for collection; the coumarone resin that is not filtered by the sieve-granule opening enters the grinder (BS-10L). This grinder is a horizontal grinder, and its power comes from electricity. The connected voltage is 220V, and its function is to grind the coumarone resin to achieve excellent performance.

[0011] The described discharge pipe housing is made of 304 stainless steel, which is light in weight and has good corrosion resistance.

[0012] The described weight sensor (MT1022-3kg) has a measuring range from 0.3 kg to 500 tons and is applicable to various weighing devices such as platform scales, single-point, shear beam, and S-type and spoke-type scales. It can convert the mass signal into a measurable digital signal with a digital signal frequency of 50HZ, and the electrical energy is provided by a battery, which is 24V.

[0013] The described electric switch (DZ47S 1P 16A) is connected to the programmable logic controller (FX1S) through wires and is controlled by the programmable logic controller to control the opening and stopping of the material discharge.

[0014] For the described programmable logic controller (FX1S), its input module is used to receive and collect input signals (50HZ), the output module is used to control the opening and closing of the electric switch, and the central processing unit, memory, programmer, etc. are mainly used for the processing of the collected weight digital signals. The preset value can be adjusted arbitrarily according to the actual situation. When the weight is greater than the preset value, the programming logic controller controls the closing of the electric switch and the material discharge stops; otherwise, the material discharge continues.

[0015] This device is used in the production process of coumarone resin particles. In view of the problems of large floor area of traditional coumarone resin particle production machines, unstable quality of resin particles, and high manual dependence of coumarone resin particles, a coumarone resin particle production device with automatic loading is designed. The steel belt of this production device is unfolded in a spiral manner, which greatly reduces the floor area without changing the length of the steel belt; a sieve particle opening is designed to control the particle size of coumarone resin particles below 5mm, ensuring good performance of coumarone resin; a weight sensor is involved at the material receiving port to automatically weigh. After reaching the set weight, it controls the opening and closing of the material discharge port with a signal, reducing the manual dependence at the collection site of coumarone particles.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] The feeding machine is supported by a bracket and is suspended above the beginning of the spiral steel belt channel. The feeding port of the feeding pipeline is connected to the discharging port of the coumarone resin reaction kettle. The discharging port of the feeding pipeline is located above the beginning of the spiral steel belt channel, serving to transport the coumarone resin to the spiral steel belt channel. The cross-section of the spiral steel belt pipeline is rectangular. The upper layer is equipped with a steel belt to transport the coumarone resin. It is hollow inside and sealed on all four sides, capable of storing cooling water. The outlet of the cooling water pipe communicates with the wall of the uppermost spiral steel belt channel, allowing the cooling water to be input into the interior of the spiral steel belt channel. The spraying device is installed below the spiral steel belt channel. The water spraying nozzle of the spraying device is connected to the bottom of the spiral steel belt channel, and the connection is sealed by welding to prevent leakage of the cooling water. The water spraying nozzle of the spraying device communicates with the interior of the spiral steel belt channel, enabling the cooling water to be sprayed onto the bottom of the conveyor steel belt. The terminal of the spiral steel belt channel is connected to the inlet of the sieve-grinding machine and is fixed with cross screws. The sieve-grinding machine is divided into upper and lower layers. The first conveyor belt (located in the upper layer) is in close contact with the conveyor steel belt of the spiral steel belt channel to continue transporting the coumarone resin. The first conveyor belt is drilled with through holes, namely sieve holes, which are densely distributed on the surface of the first conveyor belt in a square matrix. The terminal of the first conveyor belt is in contact with the inlet of the grinding machine, and the outlet of the grinding machine is tightly welded to the first discharge port. The second conveyor belt is located in the lower layer and transports the coumarone resin towards the second discharge port. The discharge pipeline is fixedly connected to the first discharge port with cross screws, and the discharge nozzle is installed at the terminal of the discharge pipeline. The weight sensor is placed below the discharge nozzle. The discharge nozzle consists of an electric switch and a programmable logic controller. The electric switch is located at the tip of the discharge nozzle, and the programmable logic controller is installed on one side of the discharge nozzle.

[0025] The coumarone resin enters the feeding machine pipeline from the discharge port of the coumarone resin reactor. The internal nozzle of the feeding machine divides the continuous fluid into uniform droplets. The coumarone resin droplets drip from the discharge port of the feeding machine onto the spiral steel belt pipeline. The cooling water pump of the cooling water pipe generates power to lift the cooling water below 75°C from the ground to the height of the highest spiral steel belt pipeline and introduce the cooling water into the inside of the spiral steel belt pipeline. At this time, the coumarone resin droplets are cooled and solidified. The cooling water flows downward due to gravity and flows into the spray device pipeline system. Through the power lift of the spray device pump, the water is sprayed at the bottom of the spiral steel belt, playing a role in the secondary cooling of the coumarone resin. The coumarone resin particles are conveyed by the spiral steel belt to the inlet of the sieving and grinding machine. The coumarone resin particles continue to be conveyed by the first conveyor belt. The coumarone resin particles smaller than 5 mm fall onto the second conveyor belt, and the second conveyor belt conveys the coumarone resin to the second discharge port. The coumarone resin larger than 5 mm is fed into the grinding machine, and the grinding machine grinds the fed coumarone resin to reduce its particle size. The ground coumarone resin particles reach the first discharge port due to gravity. Both the first discharge port and the second discharge port are connected by a discharge pipeline. The coumarone resin enters the collection bag from the discharge nozzle along the discharge pipeline. The collection belt is placed on the weight sensor, and the weight sensor converts the mass signal into a measurable digital signal with a signal frequency of 50 HZ. The digital signal is received and collected by the input module. The central processing unit, memory, programmer, etc. are mainly used to process the collected weight digital signal. When the weight is greater than the preset value, the programming logic controller controls the closing of the electric switch and the discharge is closed. On the contrary, the programming logic controller controls the opening of the electric switch and the discharge continues. The preset value can be adjusted arbitrarily according to actual needs.

[0026] This device is mainly applied to the production process of coumarone resin particles. In view of the many significant drawbacks of traditional coumarone resin particle production machines, such as a rather large floor area, lack of stability in the quality of the produced resin particles, and a great dependence on labor in the entire production process, etc. Therefore, a coumarone resin particle production device with an automatic loading function is designed. The steel belt used in this production device unfolds in a spiral manner, and on the premise of maintaining the same length of the steel belt itself, it greatly reduces the occupied space area. In addition, a sieving port is specially designed. Through this design, the particle size of the coumarone resin particles can be effectively controlled strictly below 5 mm, effectively ensuring that the coumarone resin has excellent performance. A weight sensor is set at the position of the material receiving port, which can realize the function of automatic weighing. Once the preset weight is reached, it will accurately control the opening and closing state of the discharge port with a signal, significantly reducing the dependence on manual operation in the process of collecting coumarone particles.
