Description

Technical Field

[0001] The invention belongs to the technical field of mixers, and in particular relates to a mixer capable of multiple loading, whole-granulation and mixing integration. Background Art

[0002] In order to ensure the stability and consistency of product quality in the fields of pharmaceuticals, food, chemicals, etc., it is necessary not only to process the materials into whole particles, but also to mix a variety of raw materials with different properties. Therefore, whole particle equipment and mixing equipment are widely used in these fields.

[0003] Traditionally, granulating equipment and mixing equipment are separate. Materials need to be transferred to mixing equipment after granulating, which not only makes the production process cumbersome, but also increases the loss, contamination risk and manual operation cost during material transfer. If the functions of granulating equipment and mixing equipment can be integrated, it can greatly save time in the production process, thereby increasing work efficiency.

[0004] The current whole-grain mixing integrated equipment has a receiving port and a feeding port that are integrated, resulting in insufficient flexibility during material transportation and receiving, and prone to blockage. Therefore, designing a device with a receiving port and a feeding port that can be separated and connected can help reduce equipment downtime caused by material blockage. At the same time, the staff can easily separate the two parts, thereby improving the maintenance efficiency of the equipment and reducing maintenance costs. Summary of the invention

[0005] The main purpose of the present invention is to provide a mixer that can load whole particles for multiple times and integrate mixing, so as to solve the problem that after the feed port of the equipment hopper is separated from the feed component, the feed port is in an open state, resulting in the loss of part of the raw materials from the open position.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: in the process of connecting the first pipeline and the second pipeline, the second pipeline squeezes the block downward. Since the contact surface between the block and the second pipeline is inclined downward toward the center of the placement disk, when the block is squeezed, it will move toward the outer direction of the placement disk, and at the same time, the spring is squeezed to put the spring in a compressed state. The slide bar plays a limiting role in this process, so that the block will only move along the direction of the connection line between the center of the placement disk and the center of gravity of the spring, ensuring the stability and controllability of the block movement. When the block is completely moved into the placement disk, the second pipeline goes deeper into the first pipeline for a very short distance, and the first sensor contacts the second sensor, and signals are exchanged between the two. The second sensor transmits the exchange signal to the solenoid valve, and then the solenoid valve opens the valve to allow the whole grained raw materials to enter the hopper. After entering, the lifting mechanism controls the relative distance between the fork frame and the fixed frame again to separate the first pipe from the second pipe. During the separation process, the first sensor and the second sensor are separated first. After separation, the second sensor transmits an electrical signal to the solenoid valve, and the solenoid valve is closed. Then the second pipe continues to move up and separates from the first pipe. Under the force of the spring to restore the original state, the block moves along the slide bar. Finally, multiple blocks merge to close the pipe opening of the first pipe. Repeating the above process can achieve multiple feeding and whole grain mixing, and effectively prevent the raw materials from spilling out of the pipe opening of the first pipe during the mixing of raw materials in the hopper, causing raw material loss.

[0007] The present invention provides a mixer capable of multiple loading and whole-grain mixing and integration, comprising a blanking machine, a whole-grain component, a hopper, a lifting mechanism, a fork frame, a fixed frame, and a connecting mechanism, wherein the connecting mechanism comprises a first pipeline, a second pipeline, a third pipeline, and a switch assembly, wherein the switch assembly comprises a stopper, a spring, a placement plate, a slide bar, an adjusting bolt, a nut, a solenoid valve, a first sensor, and a second sensor, wherein the fork frame and the fixed frame are both arranged on the lifting mechanism, the hopper is arranged on the fixed frame, the first pipeline is arranged on the hopper, the placement plate is arranged on the first pipeline, a groove is provided on the inner wall of the placement plate, the slide bar and the stopper are both arranged in the groove, a slide groove is provided on the stopper, and the stopper is slidably connected with the slide bar, The spring is arranged in the groove, one end of the spring abuts against the stopper, the other end of the spring abuts against the placement plate, the nut is arranged on the placement plate, the adjusting bolt is threadedly connected to the nut, the spring is sleeved on the bolt, the whole grain component is arranged on the fork frame, the second pipeline is arranged on the whole grain component, the blanking machine is arranged at one end of the whole grain component away from the second pipeline, the solenoid valve is arranged in the second pipeline, the second sensor is arranged on the second pipeline, and the solenoid valve is electrically connected to the second sensor by signal, the first sensor is arranged on the placement plate, the first sensor is electrically connected to the second sensor by signal, and the first sensor is electrically connected to the lifting mechanism by signal.

[0008] The above-mentioned technical scheme of the present application has at least the following technical effects: the contact surface between the block and the second pipe is inclined downward toward the center of the placement disk, so when the second pipe squeezes downward and the block is squeezed, it will move toward the outer side of the placement disk; the spring will inevitably be damaged during long-term repeated compression and stretching, resulting in insufficient elastic recovery force, making it impossible for multiple blocks to merge and close the pipe opening of the first pipe. At this time, the adjusting bolt can be rotated to push the block to slide along the slide bar, and finally the multiple blocks can be merged to close the pipe opening of the first pipe; the slide bar plays a limiting role, so that the block will only move along the direction of the connecting line between the center of the placement disk and the center of gravity of the spring, ensuring the stability and controllability of the block movement.

[0032] In order to improve the problem in the related art that after the feed port of the equipment hopper is separated from the feed assembly, the feed port is in an open state, resulting in the loss of part of the raw materials from the open portion, the embodiments of the present application provide the following solution.

[0033] Please also read Figure 1 , Figure 3 as well as Figure 6, including a blanking machine 1, a granulating component 2, a hopper 3, a lifting mechanism 4, a fork frame 5, a fixed frame 6, and a connecting mechanism 7, wherein the connecting mechanism 7 includes a first pipe 71, a second pipe 72, a third pipe 73, and a switch assembly 74, wherein the switch assembly 74 includes a stopper 741, a spring 742, a placement plate 743, a slide bar 744, an adjustment bolt 745, a nut 746, a solenoid valve 747, a first sensor 748, and a second sensor 749, wherein the fork frame 5 and the fixed frame 6 are both arranged on the lifting mechanism 4 The hopper 3 is fixedly connected to the fixing frame 6, the first pipe 71 is movably connected to the hopper 3, the placement plate 743 is movably connected to the first pipe 71, the inner wall of the placement plate 743 is provided with a groove, the slide bar 744 and the stopper 741 are both arranged in the groove, the slide bar 744 is fixedly connected to the placement plate 743, a slide groove is provided on the stopper 741, the stopper 741 is slidably connected to the slide bar 744, the spring 742 is arranged in the groove, the spring 742 One end of the spring 742 abuts against the stopper 741, the other end of the spring 742 abuts against the placement plate 743, the nut 746 is bonded to the placement plate 743, the adjusting bolt 745 is threadedly connected to the nut 746, the spring 742 is sleeved on the adjusting bolt 745, the whole grain component 2 is fixedly connected to the fork frame 5, the second pipe 72 is movably connected to the whole grain component 2, the blanking machine 1 is movably connected to one end of the whole grain component 2 away from the second pipe 72, a vibrator can be installed on the blanking machine 1, and the third pipe 73 needs to be made of rubber material, the solenoid valve 747 is fixedly connected in the second pipe 72, the second sensor 749 is fixedly connected to the second pipe 72, and the solenoid valve 747 is electrically connected to the second sensor 749, the first sensor 748 is fixedly connected to the placement plate 743, the first sensor 748 is electrically connected to the second sensor 749, and the first sensor 748 is electrically connected to the lifting mechanism 4.

[0034] With such arrangement, when the equipment starts to operate, the required raw materials are first put into the blanking machine 1. Under the action of the vibrator, the raw materials are accelerated along the blanking machine 1 into the third pipe 73. The third pipe 73 made of rubber can greatly alleviate the influence of the vibrator on the parts below the third pipe 73. Then the raw materials enter the whole grain component 2 and are sorted into granules and temporarily stored in the second pipe 72 and the whole grain component 2. Then the lifting mechanism 4 controls the relative distance between the fork frame 5 and the fixed frame 6 to connect the first pipe 71 and the second pipe 72. Then the granulated raw materials enter the hopper 3 and start mixing. When the first pipe 71 is connected to the second pipe 72, the second pipe 72 squeezes the block 741 downward. Since the contact surface between the block 741 and the second pipe 72 is inclined downward toward the center of the placement plate 743, when the block 741 is squeezed, it will move toward the outer side of the placement plate 743, and at the same time, the spring 742 is squeezed to make the spring 742 in a compressed state. The slide bar 744 plays a limiting role in this process, so that the block 741 will only move along the direction of the connecting line between the center of the placement plate 743 and the center of gravity of the spring 742, ensuring the stability and controllability of the movement of the block 741. When the block 741 is completely moved into the placement plate 743, the second pipe 72 goes deeper into the first pipe 71 for a very short distance, and the first sensor 748 comes into contact with the second sensor 749, and signals are exchanged between the two. The second sensor 749 transmits the exchange signal to the solenoid valve 747, and then the solenoid valve 747 opens the valve to allow the whole grained raw materials to enter the hopper 3. After entering, the lifting mechanism 4 controls the relative distance between the adjustment fork frame 5 and the fixing frame 6 again to separate the first pipe 71 from the second pipe 72. During the separation process, the first sensor 748 and the second sensor 749 are separated first. After separation, the second sensor 749 transmits an electrical signal to the electromagnetic valve 747, and the electromagnetic valve 747 is closed. Then the second pipe 72 continues to move upward and separates from the first pipe 71. The block 741 moves along the slide bar 744 under the force of the spring 742 to restore the original state. Finally, multiple blocks 741 merge to close the pipe opening of the first pipe 71. Repeating the above process can achieve multiple feeding and whole grain mixing. The combination of nut 746 and adjusting bolt 745 is used for emergency treatment. The spring 742 will inevitably be damaged during long-term repeated compression and stretching, resulting in insufficient elastic recovery force, making it impossible for multiple blocks 741 to merge and close the pipe opening of the first pipe 71. At this time, the adjusting bolt 745 can be rotated to push the block 741 to slide along the slide bar 744, and finally the multiple blocks 741 can be merged to close the pipe opening of the first pipe 71.

[0035] Optionally, in some embodiments, please refer to Figure 1 , Figure 2 as well as Figure 4The lifting mechanism 4 includes a rotating swing arm 41, a base plate 42 and a lifting assembly 43. The lifting assembly 43 includes a screw lifting column 431 and a hydraulic lifting column 432. The screw lifting column 431 is fixedly connected to the side of the base plate 42 away from the hopper 3. The hydraulic lifting column 432 is fixedly connected to the side of the base plate 42 close to the hopper 3. The rotating swing arm 41 is rotatably connected to the screw lifting column 431. The fork frame 5 is fixedly connected to the rotating swing arm 41. The hydraulic lifting column 432 is also fixedly connected to a first rotating motor 10. The fixed frame 6 is fixedly connected to the output end of the first rotating motor 10.

[0036] With such a configuration, the lifting assembly 43 uses two lifting systems, the screw lifting column 431 and the hydraulic lifting column 432. The lifting speed of the screw lifting column 431 is lower than that of the hydraulic lifting column 432. The screw lifting column 431 is more stable when controlling the height and the connection between the second pipeline 72 and the first pipeline 71. The screw lifting column 431 adjusts the height of the rotating swing arm 41, and then the rotating swing arm 41 rotates to drive the fork frame 5 to rotate, and the blanking machine 1 on the fork frame 5 is transferred to the bottom of the raw material outlet. After loading the raw material, the rotating swing arm 41 rotates to transfer the fork frame 5 to the top of the fixed frame 6, that is, the whole grain component 2 is rotated to the top of the hopper 3, and then the screw lifting assembly slowly docks the second pipeline 72 with the first pipeline 71. The first rotating motor 10 is used to rotate the fixed frame 6 to drive the hopper 3 to rotate. After multiple loading and whole graining, the raw materials need to be mixed in the hopper 3. The first rotating motor 10 drives the hopper 3 to rotate, which is conducive to more uniform mixing of the raw materials.

[0037] Optionally, in some embodiments, please refer to Figure 2 as well as Figure 4 The hopper 3 is provided with a stirring mechanism 8, and the stirring mechanism 8 includes a stirring drive motor 81, a stirring shaft 82, a stirring blade 83 and a sealing ring 84. The stirring drive motor 81 is fixedly connected to the end of the hopper 3 away from the first pipe 71, and the sealing ring 84 abuts against the connection between the stirring drive motor 81 and the hopper 3. The stirring shaft 82 is fixedly connected to the output end of the stirring drive motor 81, and the stirring blade 83 is bonded to the stirring shaft 82. The stirring blade 83 becomes larger from the end close to the sealing ring 84 to the end away from the sealing ring 84, and the stirring blade 83 is spiral.

[0038] With such arrangement, the stirring mechanism 8 as a whole allows the raw materials in the hopper 3 to be mixed more evenly. After the equipment has been loaded with whole grains for multiple times, the plurality of blocks 741 are combined to close the pipe opening of the first pipe 71, and the stirring drive motor 81 is started. The output end of the stirring drive motor 81 drives the stirring shaft 82 to rotate. The sealing ring is used to isolate the stirring drive motor 81 and the raw materials to prevent the raw materials from scratching and damaging the stirring drive motor 81. The stirring blade 83 is bonded to the stirring shaft 82, and becomes larger and larger from the end close to the sealing ring 84 to the end away from the sealing ring 84. When rotating, the raw materials will be driven by the stirring blade 83 to move from the direction of the sealing ring 84 to the direction of the first pipe 71, and cooperate with the first rotating motor 10 to drive the hopper 3 to rotate, thereby promoting uniform mixing of the raw materials.

[0039] Optionally, in some embodiments, please refer to Figure 4 as well as Figure 7 A granulating mechanism 9 is arranged inside the granulating component 2, and the granulating mechanism 9 includes a screen 91, a rotary knife 92, a converter 93, a second rotating motor 94 and a placement rack 95. The placement rack 95 is fixedly connected to the inner wall of the granulating component 2, the converter 93 is fixedly connected to the placement rack 95, the rotary knife 92 is rotatably connected to the converter 93, the second rotating motor 94 is fixedly connected to the rotating swing arm 41, and the output end of the second rotating motor 94 is transmission-connected to the converter 93, and the screen 91 is clamped on one end of the inner wall of the granulating component 2 away from the rotary knife 92.

[0040] With such arrangement, the raw material enters the granulation component 2 through the blanking machine 1, and the second rotating motor 94 is started. The output end of the second rotating motor 94 is connected to the converter 93. The converter 93 is internally provided with a transmission gear that has a transmission effect, which is equivalent to changing the rotation direction of the output end of the second rotating motor 94, and converting the rotational force perpendicular to the rotation direction of the rotary knife 92 into a rotational force consistent with the rotation direction of the rotary knife 92. Therefore, the second rotating motor 94 provides power for the rotation of the rotary knife 92, and the rotary knife 92 rotates at a high speed to pelletize the raw material. The composite particle size of the pelletized raw material is standard and will pass through the screen 91 into the second pipe 72, and will be intercepted by the solenoid valve 747. The screen 91 is clamped in the granulation component 2, and the user can reasonably replace the screen 91 with different aperture sizes according to the target particle size.

[0041] Optionally, in some embodiments, please refer to Figure 8The hopper 3 is provided with a discharge port 11, and a blocking door 12 is rotatably connected to the discharge port 11. The blocking door 12 is provided with a hydraulic hinge 13, one end of the hydraulic hinge 13 is fixedly connected to the blocking door 12, and the other end of the hydraulic hinge 13 is fixedly connected to the hopper 3. When the stirring blade 83 is working, the stirring blade 83 drives the mixing spiral to convey, and the mixed material will pass through the discharge port 11.

[0042] With such arrangement, the discharge port 11 is used to pour out the mixed raw materials, and the barrier door 12 prevents the raw materials from spilling out of the discharge port 11 when the raw materials are mixed. The first rotating motor 10 rotates, driving the hopper 3 to rotate, so that the discharge port 11 is facing downward. At this time, if the barrier door 12 is not locked, under the action of its own gravity and the gravity of the raw materials in the hopper 3, the barrier door 12 opens, and the stirring blade 83 works. The stirring blade 83 drives the mixing spiral to convey the mixed materials, and the mixed materials will pass through the discharge port 11, and the mixed raw materials are poured out from the discharge port 11. Then the first rotating motor 10 continues to drive the hopper 3 to rotate until the discharge port 11 is facing upward. The barrier door 12 falls back downward under the action of gravity, and the hydraulic hinge 13 is used to buffer the speed of the barrier door 12 during the falling process, so that the barrier door 12 slowly fits with the hopper 3 to protect the barrier door 12 and the hopper 3.

[0043] Optionally, in some embodiments, please refer to Figure 8 An adsorption iron plate 14 is bonded to one end of the barrier door 12 away from the hydraulic hinge 13 , a magnetic lock 15 is fixedly connected to the hopper 3 , and the adsorption iron plate 14 is magnetically connected to the magnetic lock 15 .

[0044] With such arrangement, the magnetic lock 15 is connected to the adsorption iron plate 14 through magnetic force, and the magnetic lock 15 fixes the position of the blocking door 12. After the magnetic lock 15 releases the magnetic connection with the adsorption iron plate 14, the blocking door 12 is opened and closed under the action of gravity and the drive of the first rotating motor 10. The magnetic lock 15 can allow the blocking door 12 to firmly seal the discharge port 11.

[0045] Optionally, in some embodiments, please refer to Figure 1 , Figure 2 as well as Figure 5 An angle encoder 16 is fixedly connected to the rotating swing arm 41 for quantifying the rotation angle of the rotating swing arm 41, a guide rail 17 is fixedly connected to the fixed frame 6, a guide rod 18 is fixedly connected to the fork frame 5, a baffle 19 is bonded to the end of the guide rail 17 away from the guide rod 18, the baffle 19 and the guide rail 17 form a placement cavity, a laser transmitter 20 is bonded in the placement cavity, a groove is formed at the end of the guide rod 18 away from the fork frame 5, a laser receiver 21 is bonded in the groove, and the laser receiver 21 is electrically connected to the angle encoder 16.

[0046] With such arrangement, the first pipe 71 will go through a rotation process of the rotating swing arm 41 before being connected with the second pipe 72. During this process, when the laser receiver 21 receives the laser emitted by the laser transmitter 20, the laser receiver 21 transmits an electrical signal to the angle encoder 16. At this time, the angle encoder 16 records the rotation angle of the rotating swing arm 41. Due to the inertia of the rotating swing arm 41, it is necessary to record the rotation angle and then call back to the recorded angle. At this time, the screw rod lifting column 431 adjusts the height of the fork frame 5 and moves downward slowly. The guide rod 18 will first enter the inside of the guide rail 17, and the two begin to slide and connect. Then the first pipe 71 and the second pipe 72 are gradually connected. When the first sensor 748 contacts the second sensor 749, the guide rod 18 also happens to abut against the baffle 19. The baffle 19 is used to protect the laser transmitter 20 from being damaged by the guide rod 18.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
