Description

Technical Field

[0001] This invention belongs to the field of asphalt production batching technology, and particularly relates to a batching device for continuous production of modified asphalt. Background Technology

[0002] In the process of preparing modified asphalt, SBS plastic needs to be added to the asphalt in a certain proportion, along with other mixtures, and then sheared and mixed to prepare modified asphalt. SBS is mostly stored in packaging bags.

[0003] For example, a continuous SBS modified asphalt mixture production line with application number "CN202020358970.X" includes a batching tank, a high-shear colloid mill, and a development tank. The batching tank has an inlet at its top, and the high-shear colloid mill is located at the top of the development tank. A first water pump is installed between the batching tank and the high-shear colloid mill. The inlet and outlet of the first water pump are connected to the batching tank and the high-shear colloid mill respectively via pipes. A filter device is connected to the outlet of the high-shear colloid mill via a pipe, and the bottom of the filter device is connected to the inlet at the top of the development tank via a pipe. A discharge pipe is located at the bottom of one side of the development tank. This invention can quickly and efficiently filter the SBS and asphalt mixture discharged from the high-shear colloid mill, thereby separating the filtered good product from some large clumps, lumps, and other particles that have not been completely sheared and crushed, improving the dispersion of SBS in the asphalt, and thus improving the performance of the finished asphalt.

[0004] Based on the aforementioned existing technology, in the feeding stage, the packaging bags containing SBS particles need to be hoisted to a designated location using equipment such as overhead cranes, and then the packaging bags are cut and dismantled. After the packaging is damaged, the SBS particles fall into the batching system under their own weight, thus initiating subsequent material conveying processes. However, the cutting operation is prone to safety risks, and the specifications of the opening in the packaging bags are difficult to control precisely, resulting in insufficient stability in material conveying and ultimately interfering with the normal progress of the asphalt production process. Summary of the Invention

[0005] This invention provides a batching device for continuous production of modified asphalt, addressing the problem in existing technologies where, during the feeding stage, packaging bags containing SBS particles need to be hoisted to a designated location using overhead cranes or similar equipment, followed by cutting and dismantling. After the packaging is damaged, the SBS particles fall into the batching system under their own weight, thus initiating subsequent material conveying processes. However, the cutting operation is prone to safety risks, and the specifications of the broken packaging bags are difficult to control precisely, resulting in insufficient stability in material conveying and ultimately disrupting the normal progress of the asphalt production process.

[0006] The present invention adopts the following technical solution: a batching device for continuous production of modified asphalt, including a batching seat, a movable swing arm rotatably connected to the outer side of the batching seat, a driven gear coaxially mounted on the outer side of the movable swing arm, and a base plate fixedly connected to the top surface of the movable swing arm. An unfolding push rod is fixedly connected to the top surface of the base plate, an extension arm is fixedly connected to the top of the unfolding push rod, a top plate is fixedly connected to the bottom surface of the extension arm, and a longitudinal groove is opened inside the extension arm, and an adjusting push rod is fixedly connected inside the longitudinal groove. The bottom end of the adjustable push rod is fixedly connected to a movable support, the inner side of the movable support is fixedly connected to a connecting plate, and the inner side of the connecting plate is fixedly connected to a hopper. A mounting frame is fixedly connected to the bottom of the hopper. A drive motor is installed at the front end of the mounting frame. An output shaft is provided on the rear side of the drive motor, and a drive screw is installed on the output shaft. A longitudinal groove is opened inside the mounting frame, and a displacement support is installed inside the longitudinal groove. Two extension plates are fixedly connected to the outer side of the displacement support in opposite directions. A directional motor is fixedly connected to the outer side of the extension plates. A mounting plate is rotatably connected to the inner side of the two extension plates. The rear output shaft of the directional motor is connected to the mounting plate. A cutter is fixedly connected to the top surface of the mounting plate.

[0007] In a further technical solution, the main body of the hopper is a semi-circular structure, and the hopper is used to carry packaging bags. A longitudinal groove is provided at the bottom of the outer circumference of the hopper. The longitudinal groove is a feeding groove, which is matched with the cutter. The mounting frame is arranged parallel to the feeding groove.

[0008] A further technical solution is that an installation bracket is fixedly connected to the outer peripheral surface of the dispensing base. The installation bracket has an L-shaped structure and there are two installation brackets. The two installation brackets are fixedly arranged opposite each other on the front and rear sides of the dispensing base. The outer side of each installation bracket is fixedly connected to an installation side plate, which is perpendicular to the installation bracket.

[0009] In a further technical solution, a swing arm motor is fixedly connected to the outer side of the mounting side plate, and a drive gear is fixedly connected to the side of the swing arm motor closest to the mounting side plate. The drive gear meshes with the driven gear for transmission, and the drive gear and the driven gear together form a transmission structure.

[0010] In a further technical solution, the inner bottom surface of the mixing seat is inclined to the left, and a support frame is fixedly connected to the bottom surface of the mixing seat. A through groove is opened on the left side of the mixing seat, and a flow-concentrating hood is fixedly connected inside the through groove on the left side of the mixing seat. The flow-concentrating hood is a frustoconical structure that is thinner on the left and thicker on the right.

[0011] A further technical solution is that a feeding pipe is fixedly connected to the left side of the flow-concentrating hood. The feeding pipe has an internally hollow pipe structure and is connected to the flow-concentrating hood. A discharge pipe is fixedly connected to the bottom of the outer circumference of the feeding pipe.

[0012] In a further technical solution, the feeding pipe and the unloading pipe together form a feeding and unloading structure, and a feeding motor is fixedly connected to the left side of the feeding pipe, and a feeding component is installed on the right output shaft of the feeding motor, the main body of the feeding component being a spiral structure.

[0013] In a further technical solution, the feeding component and the feeding motor together form a conveying structure to the left, and a guide rod is fixedly connected to the bottom end surface of the base plate.

[0014] In a further technical solution, the guide rod is provided in four places, wherein every two horizontally adjacent guide rods form a group, and the two groups of guide rods are respectively fixedly installed on the bottom end surface of the two top plates, and the bottom plate has through holes that match the guide rods.

[0015] In a further technical solution, a guide slider is fixedly connected to the outer side of the movable support. The guide slider has a structure that protrudes from the movable support. The movable support is slidably disposed in the longitudinal groove of the extension arm through the guide slider. A flipping motor is fixedly connected to the outer side of the movable support. The flipping motor is used to drive the connecting plate and the hopper to rotate.

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: In this invention, a multi-dimensional position control system for the hopper is constructed through a synergistic transmission structure consisting of a movable swing arm, a driven gear, an unfolding push rod, an extension arm, and an adjustable push rod. The swing arm motor drives the drive gear to mesh with the driven gear on the outside of the movable swing arm, causing the movable swing arm to rotate around the feeding seat, thus achieving flexible adjustment of the hopper's horizontal orientation. The extension and retraction of the unfolding push rod can drive the extension arm and the hopper to move up and down, adapting to the needs of receiving packaging bags of different heights. The adjustable push rod drives the connecting plate and the hopper to move horizontally through the movable support, accurately aligning the packaging bag placement position. Without the need for external equipment such as cranes for hoisting, the device itself can stably receive the packaging bag into the hopper, simplifying the feeding process and improving the convenience and efficiency of the feeding process.

[0017] In this invention, a fully automated cutting structure is constructed using a mounting frame, a drive motor, a drive screw, a directional motor, and a cutter. After the drive motor starts, its output shaft drives the drive screw to rotate, causing the displacement support to move smoothly along the longitudinal groove of the mounting frame, thereby driving the extension plate and the cutter to adjust their cutting positions synchronously. The directional motor drives the mounting plate to rotate through its output shaft, precisely adjusting the cutting angle of the cutter, allowing the cutter to accurately cut the packaging bags along the hopper's feed chute. The entire cutting process requires no manual intervention or external equipment, fundamentally eliminating safety hazards during the cutting process and ensuring the safety of the production process.

[0018] In this invention, stable material conveying is achieved through the synergistic effect of cutting precision control and material guiding structure. The threaded transmission structure of the drive screw can accurately lock the movement trajectory of the cutter, and the angle positioning function of the directional motor ensures that the cutting angle is consistent for each cut, thus standardizing the tear specifications of the packaging bags. At the same time, the hopper has a semi-circular structure with a feeding groove at the bottom that matches the cutter. After cutting, the SBS particles can fall stably into the batching seat along the feeding groove, avoiding fluctuations in material conveying volume caused by inconsistent tear sizes. Combined with the material guiding and conveying effect of the inclined bottom surface of the batching seat, the flow-gathering hood, and the spiral feeding component, the material is ensured to continuously and stably enter the subsequent processes, effectively avoiding interference of material conveying problems with the asphalt production process.

The rear output shaft of the directional motor 6011 is connected to the mounting plate 6012. A fixed top surface of the mounting plate 6012 is... The modified asphalt batching material is constructed by connecting the cutter 6013, the batching seat 1, the movable swing arm 2013, the driven gear 2014, the base plate 2015, the unfolding push rod 2016, the extension support arm 3, the top plate 301, the adjusting push rod 3012, the movable support 3013, the connecting plate 401, the hopper 4011, the mounting frame 5, the drive motor 501, the drive screw 5011, the displacement support 6, the extension plate 601, the directional motor 6011, the mounting plate 6012, and the cutter 6013. It can realize the basic functions of the hopper 4011 carrying packaging bags, adjusting the position of the components through the push rod and the motor, and the cutter 6013 cutting the packaging bags.

[0023] Specifically, the main body of the hopper 4011 is a semi-circular structure, and the hopper 4011 is used to carry packaging bags. A longitudinal groove is opened at the bottom of the outer peripheral surface of the hopper 4011. This longitudinal groove is the feeding groove 4012. The feeding groove 4012 matches the cutter 6013. The mounting frame 5 is set parallel to the feeding groove 4012. With the semi-circular structure of the hopper 4011 adapted to carry the packaging bags, the feeding groove 4012 at its bottom end is precisely matched with the cutter 6013. The mounting frame 5 is set parallel to the feeding groove 4012, which can ensure that the cutter 6013 accurately cuts the packaging bags and helps the materials flow smoothly out of the feeding groove 4012.

[0024] Specifically, a mounting bracket 2 is fixedly connected to the outer circumferential surface of the dispensing base 1. The mounting bracket 2 has an L-shaped structure and there are two mounting brackets 2. The two mounting brackets 2 are fixedly arranged opposite each other on the front and rear sides of the dispensing base 1. The outer side of each mounting bracket 2 is fixedly connected to a mounting side plate 201. The mounting side plate 201 is perpendicular to the mounting bracket 2. By fixing two L-shaped mounting brackets 2 opposite each other to the front and rear of the dispensing base 1 and fixing the vertically arranged mounting side plate 201 on the outer side of the mounting bracket 2, a stable mounting support foundation is provided for the subsequent swing arm drive related components.

[0025] Specifically, a swing arm motor 2011 is fixedly connected to the outer side of the mounting side plate 201. A drive gear 2012 is fixedly connected to the side of the swing arm motor 2011 closest to the mounting side plate 201. The drive gear 2012 meshes with the driven gear 2014 for transmission, and the drive gear 2012 and the driven gear 2014 together form a transmission structure. The swing arm motor 2011 on the mounting side plate 201 drives the drive gear 2012 to rotate. The drive gear 2012 meshes with the driven gear 2014 on the moving swing arm 2013 for transmission, thereby realizing the rotation adjustment of the moving swing arm 2013 and thus changing the position of the hopper 4011.

[0026] Specifically, the bottom surface of the mixing seat 1 is inclined to the left, and a support frame 101 is fixedly connected to the bottom surface of the mixing seat 1. A through groove is opened on the left side of the mixing seat 1, and a flow-gathering hood 1011 is fixedly connected inside the through groove on the left side of the mixing seat 1. The flow-gathering hood 1011 is a frustoconical structure that is thinner on the left and thicker on the right. The inclined bottom surface inside the mixing seat 1 guides the flow of materials. The support frame 101 provides stable support for the mixing seat 1. The frustoconical flow-gathering hood 1011 on the left side can gather materials and prepare for subsequent material conveying.

[0027] Specifically, a feeding pipe 1012 is fixedly connected to the left side of the flow-concentrating hood 1011. The feeding pipe 1012 is a hollow pipe structure and is connected to the flow-concentrating hood 1011. A discharge pipe 1013 is fixedly connected to the bottom of the outer periphery of the feeding pipe 1012. The feeding pipe 1012 is connected to the flow-concentrating hood 1011, and the discharge pipe 1013 is fixed to the bottom of the feeding pipe 1012. The three together form a feeding and discharging structure to guide and transport the converged material to the subsequent processing stage.

[0028] Specifically, the feeding pipe 1012 and the discharge pipe 1013 together form a feeding and discharging structure. A feeding motor 1014 is fixedly connected to the left side of the feeding pipe 1012, and a feeding component 1015 is installed on the right output shaft of the feeding motor 1014. The main body of the feeding component 1015 is a spiral structure. The feeding motor 1014 on the left side of the feeding pipe 1012 drives the spiral feeding component 1015 to rotate, which cooperates with the feeding pipe 1012 and the discharge pipe 1013 to form a stable left-side conveying structure and accurately control the amount of material conveyed.

[0029] Specifically, the feeding component 1015 and the feeding motor 1014 together form a left-side conveying structure, and a guide rod 3011 is fixedly connected to the bottom surface of the base plate 2015. The feeding component 1015 and the feeding motor 1014 ensure that the material is conveyed to the left. The four guide rods 3011 at the bottom of the base plate 2015 are fixed in groups to the bottom of the top plate 301 and match the through holes of the base plate 2015, providing guidance for the movement of the extension arm 3 and ensuring the stability of the structure movement.

[0030] Specifically, there are four guide rods 3011, with each pair of guide rods 3011 that are laterally adjacent forming a group. The two groups of guide rods 3011 are fixedly installed on the bottom surfaces of the two top plates 301. The bottom plate 2015 has through holes that match the guide rods 3011. By fixing the two groups of guide rods 3011 to the bottom surfaces of the two top plates 301 and matching the through holes of the bottom plate 2015, the guiding effect of the extension arm 3 when it moves is further enhanced, and the movement stability of the overall structure is improved.

[0031] Specifically, a guide slider 3014 is fixedly connected to the outer side of the movable support 3013. The guide slider 3014 is a structure that protrudes from the movable support 3013. The movable support 3013 is slidably disposed in the longitudinal groove of the extension arm 3 through the guide slider 3014. A flip motor 4 is fixedly connected to the outer side of the movable support 3013. The flip motor 4 is used to drive the connecting plate 401 and the hopper 4011 to rotate. By sliding the guide slider 3014 on the outer side of the movable support 3013 in the longitudinal groove of the extension arm 3, and cooperating with the flip motor 4 on the outer side of the movable support 3013 to drive the connecting plate 401 and the hopper 4011 to rotate, the position of the hopper 4011 can be flexibly adjusted and the material can be flipped to discharge, thereby improving the flexibility of material distribution.

[0032] When in use, after starting the device, the initial position is first adjusted to suit the placement requirements of the packaging bags. The swing arm motor 2011 on the outside of the mounting side plate 201 is started, and its output shaft on the side near the mounting side plate 201 drives the drive gear 2012 to rotate. Since the drive gear 2012 and the driven gear 2014 coaxially mounted on the outside of the moving swing arm 2013 form a meshing transmission relationship, under the meshing force, the moving swing arm 2013 rotates around the outside of the dispensing seat 1, thereby driving the bottom plate 2015 fixedly connected to the top surface of the moving swing arm 2013 to rotate synchronously. During this process, the dispensing seat 1 serves as the fixed base of the entire device, providing stable support for the rotation of the moving swing arm 2013 and preventing shaking during rotation. The precise meshing of the driven gear 2014 and the drive gear 2012 ensures that the rotation angle of the moving swing arm 2013 is controllable and the movement is smooth. Finally, the bottom plate 2015 and all connecting parts above the bottom plate 2015 are adjusted to the initial position that is convenient for the operator to place the packaging bags for SBS granules. After the initial position for height, horizontal distance, and angle adaptation is determined, the position of the hopper 4011 is adjusted collaboratively by multiple sets of components to accurately receive the packaging bag. First, the unfolding push rod 2016, which is fixedly connected to the top surface of the bottom plate 2015, is activated. The top of the unfolding push rod 2016 is fixedly connected to the extension arm 3, and its extension or retraction will drive the extension arm 3 to move up and down synchronously. The top plate 301, which is fixedly connected to the bottom surface of the extension arm 3, moves together with the extension arm 3. At the same time, the top plate 301, which is fixedly connected to the bottom surface of the top plate 301... Guide rod 3011 is inserted into the matching through hole inside the base plate 2015. Under the limiting and guiding action of guide rod 3011, the up and down movement of extension arm 3 is more stable, avoiding deviation, thereby realizing the adjustment of the overall height of hopper 4011 to adapt to the placement needs of packaging bags of different heights. Then, the adjusting push rod 3012, which is fixedly connected in the longitudinal groove inside the extension arm 3, is activated. The bottom end of adjusting push rod 3012 is fixedly connected to movable support 3013, and its extension and retraction movement drives movable support 3013 to move. The movable support 3013 is fixedly connected to the outer side of the guide slider 3014, which is embedded in the longitudinal groove of the extension arm 3. Under the sliding limit action of the guide slider 3014, the movable support 3013 slides smoothly along the longitudinal groove, thereby driving the connecting plate 401 fixedly connected to the inner side of the movable support 3013 to move synchronously. The hopper 4011 fixedly connected to the inner side of the connecting plate 401 adjusts the horizontal distance with the connecting plate 401 to ensure that the hopper 4011 can be accurately aligned with the position of the packaging bag to be placed later. Finally, the movable support 3013... When the flipping motor 4 fixedly connected to the outside of 013 is started, the output shaft of the flipping motor 4 is connected to the connecting plate 401 for transmission. Its rotation causes the connecting plate 401 to rotate around the inner side of the movable support 3013. The connecting plate 401 then drives the hopper 4011 to rotate synchronously, adjusting the tilt angle of the hopper 4011. Since the main body of the hopper 4011 is a semi-circular structure, the tilt angle adjustment can better fit the shape of the packaging bag, making it easier to place the packaging bag stably in the hopper 4011 and prevent the packaging bag from slipping when placed. After the packaging bag is placed in the hopper 4011, the mounting frame 5, which is fixedly connected to the bottom of the hopper 4011, serves as the mounting base for the cutting components. The drive motor 501 installed at its front end is not started immediately. First, the directional motor 6011, which is fixedly connected to the outer side of the extension plate 601 on the outer side of the displacement support 6 on the mounting frame 5, is started. The rear output shaft of the directional motor 6011 is fixedly connected to the mounting plate 6012, which is rotatably connected to the inner side of the extension plate 601. After the directional motor 6011 starts, it drives the mounting plate 6012 to rotate around the inner side of the extension plate 601. The top surface of the mounting plate 6012 is fixed... The fixed-connection cutter 6013 rotates synchronously with the mounting plate 6012 to adjust the cutting angle of the cutter 6013. At the same time, the feed groove 4012 opened at the bottom of the outer peripheral surface of the hopper 4011 is observed to ensure that the angle of the cutter 6013 is precisely matched with the groove direction of the feed groove 4012. This prepares the cutter 6013 to smoothly cut into the packaging bag and cut along the direction of the feed groove 4012 during subsequent cutting. The mounting bracket 5 is set parallel to the feed groove 4012 to further ensure that the movement trajectory of the cutter 6013 is consistent with the direction of the feed groove 4012 and avoid cutting deviation. After the angle of the cutter 6013 is calibrated, the drive motor 501 is started to cut the packaging bag. The drive screw 5011 installed on the rear output shaft of the drive motor 501 rotates as the drive motor 501 starts. Since the drive screw 5011 and the displacement support 6 installed in the longitudinal groove inside the mounting frame 5 form a threaded transmission relationship, the rotation of the drive screw 5011 is converted into the linear movement of the displacement support 6 along the longitudinal groove of the mounting frame 5. When the displacement support 6 moves, it drives the extension plate 601 fixedly connected to its outer side to move synchronously. The extension plate 601 then drives the directional motor 6011, the mounting plate 6012 and the cutter 6013 to move together along the longitudinal groove of the mounting frame 5. During this process, the cutter 6013 maintains an angle matching the feeding groove 4012 while moving, and gradually cuts into the packaging bag in the hopper 4011. It cuts the packaging bag with a uniform size along the direction of the feeding groove 4012, realizing the automated cutting of the packaging bag without the need for manual hand-held cutting and avoiding the safety risks of manual cutting. Before the packaging bag is cut, the swing arm motor 2011 installed on the outside of the mounting side plate 201 needs to be pre-driven to rotate the drive gear 2012, and gradually drive the hopper 4011 fixedly connected in the connecting plate 401 to rotate back to the top of the dispensing seat 1 after the packaging bag is loaded. At this time, the above-mentioned cutting structure is activated to cut the packaging bag. At this time, the SBS particles in the bag fall into the feeding groove 4012 at the bottom of the hopper 4011 under the action of gravity through the cut. Then, they fall into the dispensing seat 1 through the feeding groove 4012. The bottom surface of the dispensing seat 1 is an inclined structure facing the left. Under the guidance of the inclined surface, the falling SBS particles automatically flow to the left side of the dispensing seat 1. The support frame 101 fixedly connected to the bottom surface of the dispensing seat 1 provides stable support for the dispensing seat 1, preventing the dispensing seat 1 from tilting or shaking due to the material, and ensuring that the material can flow smoothly to the left. The material enters the flow-gathering hood 1011, which is fixedly connected to the left channel of the feeding seat 1. The flow-gathering hood 1011 has a frustoconical structure that is narrower on the left and wider on the right. It can gather the dispersed flow of material and prevent the material from scattering during the conveying process. It ensures that the material enters the feed pipe 1012, which is fixedly connected to the left side of the flow-gathering hood 1011. The feed pipe 1012 has a hollow internal pipe structure. The feed motor 1014, which is fixedly connected to the left side of the feed motor 1012, starts. The feed component 1015, which is installed on the right output shaft of the feed motor 1014, rotates as the feed motor 1014 starts. The main body of the feed component 1015 is a spiral structure. The structure generates a conveying force to the left when it rotates, continuously conveying the material in the feed pipe 1012 to the left. Finally, under the conveying action of the feeder 1015, the material reaches the discharge pipe 1013 fixedly connected to the bottom of the outer circumference of the feed pipe 1012, and is then conveyed to the subsequent mixing stage of modified asphalt production through the discharge pipe 1013. During this process, the continuous rotation of the feeder 1015 ensures the continuity of material conveying. Combined with the automated feeding, cutting and discharging in the early stage, it realizes continuous batching of modified asphalt production and meets the demand for continuous material supply in the production process.
