Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically a docking structure for a mixing equipment. Background Technology

[0002] Mixers, as important industrial equipment, are widely used in various industries such as chemical, pharmaceutical, food, and building materials. Their main function is to uniformly mix materials of different components to obtain a homogeneous mixture that meets process requirements. Automated Guided Vehicles (AGVs) are intelligent transportation devices with automatic navigation and path planning capabilities, enabling automated material transfer and distribution within production workshops. By combining AGVs with mixing equipment, fully automated operations from material transfer to mixing processing can be achieved, significantly improving production efficiency and product quality.

[0003] According to patent document CN217746902U, a positioning structure for a mixing machine in a feed mixing device belongs to the technical field of feed processing equipment. It primarily addresses the problem of ensuring the stability of the mixing machine assembly during existing equipment assembly, proposing the following technical solution: a base and a mixing machine are included. A positioning mechanism is provided on the base, comprising multiple support columns mounted on the outer wall of the base. A cavity ring is fixedly connected to the top outer wall of the support columns, and an outer threaded cylinder is threaded into the cavity ring. This invention, through the combination of various structures, not only facilitates material handling but also replaces the positioning rods and plates used in existing technologies with a positioning mechanism. This not only facilitates the docking of the mixing machine and the base during assembly but also limits and fixes the docked mixing machine and the base, further improving the stability of the assembly.

[0004] Considering that most mixing hopper covers on the market are fixed to the mixer frame by adjusting chains, once the servo lifting mechanism completes the clamping action of the hopper, the docking work between the hopper cover and the mixing hopper is actually completed. However, relying solely on this simple docking structure, its accuracy often cannot reach the ideal level, which to some extent limits the mixing efficiency of the mixer, thus affecting the efficiency and quality of the entire mixing process. Summary of the Invention

The sides of the plurality of second rotating rods away from the push-pull blocks are respectively rotatably connected to the outer wall of the bottom connecting shaft in a circular array, and each of the plurality of push-pull blocks is fixedly connected to a locking block on the outer side.

[0010] Preferably, the inner wall of the bottom connecting shaft is movably connected to the outer wall of the stirring rod connecting rod on the side away from the top connecting shaft, and the inner wall of the bottom connecting shaft is fixedly connected with an inner slider in a ring array. The outer walls of the multiple inner sliders are respectively slidably connected to the inner walls of the multiple grooves opened on the outer wall of the stirring rod connecting rod.

[0011] Preferably, the stirring mechanism includes a stirring rod, the bottom of which is movably connected to the middle of the bottom of the inner wall of the mixer, a stirring fan is fixedly connected to the outer wall of the stirring rod in a ring array, a connecting plate is fixedly connected to the top of the stirring rod, the inner wall of the stirring rod is hollowed out, and the inner wall of the connecting plate is provided with slots in a ring array.

[0014] Preferably, the top ends of both hydraulic push rods extend to the inner wall of the control compartment and are fixedly connected to push blocks, and the outer walls of both push blocks are rotatably connected to hinge plates.

[0015] Preferably, the inner walls of both hinge plates are rotatably connected to V-shaped rotating rods, the inner bottom of both V-shaped rotating rods are rotatably connected to the outer wall of the connecting rod, and the inner top of both V-shaped rotating rods are fixedly connected to pressure blocks.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This application incorporates a reinforcement mechanism that precisely controls the connection force between the hopper cover and the mixing hopper, thereby improving the accuracy of the connection. This structure not only ensures the stability of the mixer during operation but also significantly improves mixing efficiency and quality. Specifically, after the hopper cover is tightly closed on the top of the mixer, the reinforcement mechanism plays a crucial role in preventing loosening caused by vibration during the mixing process, which would affect the mixing effect. The hydraulic push rod, driven by the hydraulic system, pushes the push block upward, causing the V-shaped rotating rod to rotate through the hinge plate, which in turn drives the pressure block downward to press the hopper cover tightly, ensuring a tight fit. At the same time, the second pressure block, under the action of the spring, forms a clamping force with the pressure block, further fixing the hopper cover. This design not only improves working stability and prevents material leakage but also has adjustability to adapt to different hopper cover weights and volumes, enhancing the applicability and efficiency of the mixing machine.

[0019] 2. This application, by setting a stirring rod fixing mechanism, can ensure the stability of the stirring rod during operation, avoid the problem of inaccurate docking caused by vibration generated by stirring, and further improve the uniformity and efficiency of mixing. Specifically, when the hopper cover is conveyed to the top of the mixer by the chain, the stirring rod connecting rod is inserted into the inner wall of the stirring rod through the connecting plate. As the hopper cover descends, the connecting plate cooperates with the locking block to form a stable connection between the stirring rods. The descent of the hopper cover pushes the bottom of the inner wall of the connecting plate, causing the connecting shaft to move upward, driving the rotating rod to rotate and pushing the locking block to lock into the inner wall of the slot, realizing a tight connection between the hopper cover and the mixing mechanism of the mixer. After the stirring motor is started, the transmission device transmits the rotational power to the stirring rod, causing it to rotate in the mixer and stir the materials to ensure the uniformity of mixing. In addition, the mixing mixer is designed with a safety locking mechanism. The stirring motor will not start before the hopper cover is fully locked, ensuring operational safety.

[0020] 3. This application incorporates a stirring fan and stirring rod, which allows the materials to be more thoroughly stirred during the mixing process, thereby achieving a better mixing effect;

[0021] 4. By incorporating a reinforcement mechanism, this application enhances the structural strength of the entire mixer, enabling it to maintain good performance even under high load conditions and extending its service life. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figure 1-2 As shown, the present invention provides a technical solution for the docking structure of a mixing machine, including a mixing machine base 1, a mixing machine 2 fixedly connected to the inner wall of the mixing machine base 1, a reinforcing mechanism connecting plate 3 fixedly connected to the top of the outer wall of the mixing machine 2, a reinforcing mechanism 4 fixedly connected to both sides of the inner wall of the reinforcing mechanism connecting plate 3, and a hopper cover 5 movably connected to the top of the mixing machine 2.

[0033] Please see Figure 3-5The hopper cover 5 includes a hopper cover body 51. A stirring motor 52 is fixedly connected to the top of the hopper cover body 51. A stirring rod connecting rod 53 is fixedly connected to the output end of the stirring motor 52. The bottom of the stirring rod connecting rod 53 extends to the bottom of the outer wall of the hopper cover body 51. A sliding groove 54 is formed in an annular array on the outer wall of the stirring rod connecting rod 53. A stirring rod fixing mechanism 55 is fixedly connected to one side of the stirring rod connecting rod 53 extending to the bottom of the outer wall of the hopper cover body 51. The stirring rod fixing mechanism 55 includes two connecting shafts 551. The inner wall of the top connecting shaft 551 is fixedly connected to the top of the outer wall of the stirring rod connecting rod 53 extending to the bottom of the hopper cover body 51. A push-pull block 553 is rotatably connected to the annular array on the outer wall of the connecting shaft 551. A push-pull block 553 is rotatably connected to the side of multiple rotating rods 552 away from the connecting shaft 551. A second rotating rod 556 is rotatably connected to the bottom of the inner wall of multiple push-pull blocks 553. The side of multiple second rotating rods 556 away from the push-pull blocks 553 is divided into... The bottom connecting shaft 551 is rotatably connected to the outer wall of the bottom connecting shaft 551 in a ring array. The outer sides of the multiple push-pull blocks 553 are all fixedly connected to the locking blocks 554. The inner wall of the bottom connecting shaft 551 is movably connected to the outer wall of the stirring rod connecting rod 53 on the side away from the top connecting shaft 551. The inner wall of the bottom connecting shaft 551 is fixedly connected to the inner sliders 555 in a ring array. The outer walls of the multiple inner sliders 555 are respectively slidably connected to the inner walls of the multiple grooves 54 opened on the outer wall of the stirring rod connecting rod 53. The stirring mechanism 6 includes a stirring rod 61. The bottom of the stirring rod 61 is movably connected to the middle of the bottom of the inner wall of the mixer 2. The outer wall of the stirring rod 61 is fixedly connected to the stirring fan 63 in a ring array. The top of the stirring rod 61 is fixedly connected to the connecting plate 62. The inner wall of the stirring rod 61 is hollowed out. The inner wall of the connecting plate 62 is provided with the locking grooves 64 in a ring array. The inner wall of the stirring rod 61 is movably connected to the outer wall of the stirring rod connecting rod 53. The inner walls of the multiple locking grooves 64 are respectively movably connected to the outer walls of the multiple locking blocks 554.

[0034] When the hopper cover 5 is conveyed to the top of the mixer 2 by the chain, the stirring rod connecting rod 53 is inserted into the inner wall of the stirring rod 61 through the connecting plate 62. As the hopper cover body 51 continues to descend into the mixer 2, the slot 64 of the connecting plate 62 and the outer wall of the locking block 554 cooperate with each other, so that a stable connection is formed between the stirring rod 61 and the stirring rod connecting rod 53. When the hopper cover body 51 continues to descend, the bottom of the inner wall of the connecting plate 62 at the top of the stirring rod 61 pushes the connecting shaft 551 at the bottom of the outer wall of the stirring rod connecting rod 53 to move upward, thereby driving the second rotating rod 556 and the rotating rod 55 2. Rotate to push the rotating rod 552 outward, and insert the locking block 554 into the inner wall of the slot 64. At this time, the hopper cover body 51 is tightly connected to the stirring mechanism 6 on the inner wall of the mixer 2. The stirring mechanism 6 can be rotated by starting the stirring motor 52, thereby achieving efficient mixing of materials. The rotational power of the stirring motor 52 is transmitted to the stirring rod 61 through the transmission device, so that the stirring rod rotates in the mixer 2. The rotation of the stirring rod 61 drives the materials inside the mixer, so that they tumble and mix in three dimensions in the hopper, ensuring the uniformity of material mixing.

[0035] In addition, the docking structure design of this mixer also takes safety into consideration. During the docking process between the hopper cover 5 and the mixer 2, a safety locking mechanism is provided to ensure that the mixing motor 52 will not start before the hopper cover 5 is fully locked. Once the connection between the hopper cover 5 and the mixer 2 reaches the predetermined stable state, the safety locking mechanism will automatically release, allowing the mixing motor 52 to start working. This design effectively prevents safety accidents caused by improper operation and ensures the safety of operators.

[0036] The entire docking process is simple and quick, which greatly improves production efficiency, makes the entire production process smoother, reduces waiting and preparation time, and thus improves overall production efficiency while ensuring product quality.

[0037] Please see Figure 6-8Both reinforcement mechanisms 4 include control chambers 41. Hydraulic push rod connecting plates 42 are fixedly connected to the bottom of each control chamber 41. Connecting rods 44 are fixedly connected to the inner sides of each hydraulic push rod connecting plate 42. Hydraulic push rods 43 are fixedly connected to the top of the inner walls of each control chamber 41 on their adjacent sides. The tops of each hydraulic push rod 43 extend to the inner wall of the control chamber 41 and are fixedly connected to push blocks 45. Hinged plates 46 are rotatably connected to the outer walls of each push block 45. Each hinge plate 46 has a V-shaped rotating rod 47 rotatably connected to its inner wall. The bottom inner sides of the two V-shaped rotating rods 47 are rotatably connected to the outer wall of the connecting rod 44. The top inner sides of the two V-shaped rotating rods 47 are fixedly connected to a pressure block 48. The inner walls of the two pressure blocks 48 are slidably connected to a second pressure block 410. Two springs 49 are fixedly connected to the side of the two second pressure blocks 410 near the pressure block 48. The side of the two second pressure blocks 410 away from the pressure block 48 extends to the outer wall of the pressure block 48.

[0038] After the hopper cover 5 is completely covered to the top of the mixer 2, in order to prevent the mixer 2 from shaking during the mixing process of the stirring mechanism 6 on the inner wall of the mixer 2, which may cause the hopper cover 5 to become loose and thus affect the mixing effect, the reinforcement mechanism 4 in this design will play a crucial role. Specifically, after the hopper cover 5 is tightly connected to the mixer 2, the hydraulic push rod 43 in the control chamber 41 will push the push block 45 to the top under the drive of the hydraulic system. The movement of the push block 45 will push the V-shaped rotating rod 47 to rotate through the hinge plate 46. The V-shaped rotating rod 47 rotates to the top on one side of the inner wall of the hinge plate 46, so that the bottom of the V-shaped rotating rod 47 rotates around the connecting rod 44 as the axis, and then the top of the V-shaped rotating rod 47 drives the pressure block 48 to rotate downward until it covers the top of the hopper cover 5.

[0039] Under the action of the hydraulic push rod 43, the pressure block 48 will apply a downward pressure to the hopper cover 5 to ensure that the hopper cover 5 is tightly connected to the top of the mixer 2. At the same time, under the elastic force of the spring 49, the second pressure block 410 will form a stable clamping force with the pressure block 48 to further ensure the fixation of the hopper cover 5. This design not only improves the working stability of the mixer 2, but also effectively prevents material leakage caused by shaking.

[0040] In addition, the reinforcement mechanism 4 of this design has good adjustability. By adjusting the thrust of the hydraulic push rod 43, it can adapt to hopper covers 5 of different weights and volumes, so that the mixer 2 can be used for a variety of different material mixing needs. This flexibility greatly enhances the applicability and working efficiency of the mixing machine.

[0041] In summary, the docking structure of the mixer provided in this application, through the unique reinforcement mechanism 4 design, not only ensures the stability of the mixing process, but also improves the applicability and ease of operation of the equipment. This innovative design concept enables the mixer to operate more efficiently and stably in industrial production, meeting the needs of modern industry for high-efficiency and high-stability mixing equipment.

[0042] Working principle: When the hopper cover 5 is conveyed to the top of the mixer 2 via a chain, the stirring rod connecting rod 53 is inserted into the inner wall of the stirring rod 61 through the connecting plate 62. As the hopper cover body 51 continues to descend into the mixer 2, the slot 64 of the connecting plate 62 and the outer wall of the locking block 554 cooperate with each other, forming a stable connection between the stirring rod 61 and the stirring rod connecting rod 53. As the hopper cover body 51 continues to descend, the bottom of the inner wall of the connecting plate 62 at the top of the stirring rod 61 pushes the connecting shaft 551 at the bottom of the outer wall of the stirring rod connecting rod 53 to move upward, thereby driving the second rotating rod 556 and the rotating rod 552 to rotate, pushing the rotating rod 552 to move outward, and locking the locking block 554 into the inner wall of the slot 64. At this time, the hopper cover body 51 is tightly connected to the stirring mechanism 6 on the inner wall of the mixer 2, and can be activated by starting the stirring motor 52. The stirring mechanism 6 is rotated to achieve efficient mixing of materials. The rotational power of the stirring motor 52 is transmitted to the stirring rod 61 through the transmission device, causing the stirring rod to rotate inside the mixer 2. The rotation of the stirring rod 61 drives the materials inside the mixer to tumble and mix in three dimensions within the hopper, ensuring the uniformity of the material mixing. In addition, the docking structure design of this mixer also considers safety. During the docking process between the hopper cover 5 and the mixer 2, a safety locking mechanism is provided to ensure that the stirring motor 52 will not start before the hopper cover 5 is fully locked. Once the connection between the hopper cover 5 and the mixer 2 reaches the predetermined stable state, the safety locking mechanism will automatically release, allowing the stirring motor 52 to start working. This design effectively prevents safety accidents caused by improper operation and ensures the safety of operators.

[0043] After the hopper cover 5 is completely placed on top of the mixer 2, to prevent the mixer 2 from shaking during the mixing process of the stirring mechanism 6 on the inner wall of the mixer 2, which could cause the hopper cover 5 to loosen and affect the mixing effect, the reinforcement mechanism 4 in this design plays a crucial role. Specifically, after the hopper cover 5 is tightly connected to the mixer 2, the hydraulic push rod 43 in the control chamber 41, driven by the hydraulic system, will push the push block 45 to move upward. The movement of the push block 45 will push the V-shaped rotating rod 47 to rotate through the hinge plate 46. The V-shaped rotating rod 47 rotates upward on one side of the inner wall of the hinge plate 46, so that the bottom of the V-shaped rotating rod 47 rotates around the connecting rod 44 as the axis, which in turn causes the top of the V-shaped rotating rod 47 to drive the pressure block 48 to rotate downward. When the hopper cover 5 is placed on top, the pressure block 48, under the action of the hydraulic push rod 43, applies a downward pressure to the hopper cover 5, ensuring that the hopper cover 5 is tightly connected to the top of the mixer 2. At the same time, the second pressure block 410, under the elastic force of the spring 49, forms a stable clamping force with the pressure block 48, further ensuring the fixation of the hopper cover 5. This design not only improves the working stability of the mixer 2, but also effectively prevents material leakage caused by vibration. In addition, the reinforcement mechanism 4 of this design has good adjustability. By adjusting the thrust of the hydraulic push rod 43, it can adapt to hopper covers 5 of different weights and volumes, making the mixer 2 suitable for a variety of different material mixing needs. This flexibility greatly enhances the applicability and working efficiency of the mixing machine.
