Description

Technical Field

[0001] This utility model relates to the field of quantitative mixing device for fluorine-free water-repellent agents, and in particular to a quantitative mixing device for fluorine-free water-repellent agents. Background Technology

[0002] In modern industrial production, fluorine-free water-repellent agents are widely used in textiles, leather, building materials, and other fields due to their environmentally friendly and efficient properties. To ensure the stable performance of fluorine-free water-repellent agents, precise quantitative proportioning is crucial; therefore, quantitative proportioning devices for fluorine-free water-repellent agents have become indispensable key equipment in the production process.

[0003] Existing quantitative mixing devices for fluorine-free water-repellent agents have certain shortcomings in terms of the hopper and blade structure. The hopper is typically fixed, limiting the device to a single raw material. Since different fluorine-free water-repellent raw materials have varying physicochemical properties, the requirements for the hopper's material and shape differ. The fixed hopper cannot be flexibly replaced, failing to meet diverse production needs. Regarding blade replacement, traditional devices mostly rely on tools for disassembly and installation, a cumbersome process. When blades are damaged and need replacement, specific tools are required for disassembly and installation, which is time-consuming and reduces production efficiency, failing to meet the demands of high-efficiency production. Therefore, there is an urgent need to improve existing quantitative mixing devices for fluorine-free water-repellent agents to solve the aforementioned technical problems.

[0004] In response to this technical problem, this application proposes a quantitative mixing device for a fluorine-free water-repellent agent. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a quantitative mixing device for a fluorine-free water-repellent agent. When the feeding hopper needs to be replaced, pulling the lever causes the first limiting block to compress the spring, causing the first limiting block to disengage from the feeding hopper and release the feeding restriction. At this time, the feeding hopper can be removed upwards along the internal sliding groove of the placement seat. Compared with the traditional fixed feeding hopper that is only suitable for a single raw material, this device can be quickly replaced with a feeding hopper suitable for different materials to meet diverse production needs. The rotation of the threaded rod drives the circular shaft to move. When the circular shaft moves to the left, it compresses the right end of the upper and lower rotating blocks, causing its left end to open and close, releasing the fixation on the fan blade. When installing the fan blade, when the protective box on the outer wall of the right side of the fan blade abuts against the connecting block, the threaded rod inside the connecting block can be turned, causing the circular shaft to move to the left and compress the rotating block, allowing the left end of the rotating block to engage with the slot of the second limiting block on the right end of the fan blade, completing the installation. This device does not require tool disassembly; the damaged fan blade can be replaced simply by turning the threaded rod, significantly improving work efficiency compared to traditional methods.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quantitative dispensing device for a fluorine-free water-repellent agent includes a dispensing device body. A placement seat is located on the top of the dispensing device body. A hopper is connected to the interior of the placement seat via a fixing assembly. A motor is mounted on the outer wall of the top of the dispensing device body. A rotating rod is mounted on the drive end of the motor. A fixing plate is fixedly connected to the bottom of the rotating rod. A stirring rod is mounted on the outer wall of the top of the fixing plate. A connecting block is fixedly connected to the outer wall of the stirring rod. A threaded rod is located inside the connecting block. A round shaft is threadedly connected to the outer wall of the threaded rod. A second fixing block is fixedly connected to the outer wall of the connecting block. A fan blade is connected to the outer wall of the second fixing block via a locking assembly. A protective box is located on the right outer wall of the fan blade.

[0008] Furthermore, the fixing component includes a pull rod disposed inside the placement seat, one end of the pull rod being fixedly connected to a first limiting block, the first limiting block being disposed on the outer wall of the hopper, and a spring being sleeved on the outer wall of the pull rod.

[0009] Furthermore, the locking assembly includes a rotating block disposed inside the second fixed block, and a second limiting block is disposed at the left end of the rotating block, the left outer wall of the second limiting block being fixedly connected to the outer wall of the fan blade.

[0010] Furthermore, a first fixing block is fixedly connected to the outer wall of the hopper, and one end of the spring is disposed on the outer wall of the first limiting block.

[0011] Furthermore, the outer wall on the right side of the protective box is disposed on the outer wall on the left side of the connecting block, and the outer wall of the circular shaft is disposed on the outer wall of the rotating block.

[0012] Furthermore, a fixing rod is provided inside the stirring rod, a groove is provided on the outside of the stirring rod, and a locking block is fixedly connected to the outer wall of the fixing rod.

[0013] Furthermore, the outer wall of the top end of the fixing rod is provided with threads, and a nut is threadedly connected to the outer wall of the threads.

[0014] Furthermore, a placement platform is fixedly connected to the outer wall of the main body of the water-repellent quantitative proportioning device, and a discharge port is provided at the bottom of the main body of the water-repellent quantitative proportioning device.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the quantitative proportioning device for the fluorine-free water-repellent agent, by pulling the pull rod, drives the first limiting block to squeeze the spring, so that the first limiting block disengages from the feeding hopper and contacts the limiting of feeding. At this time, the feeding hopper can be taken out upward along the sliding groove inside the placement seat. Compared with the traditional fixed feeding hopper that can only be adapted to a single raw material, this device can be quickly replaced to adapt to different materials, thereby meeting diversified production needs.

[0017] 2. In this utility model, the rotating threaded rod drives the round shaft to move on the threaded rod. When the round shaft moves to the left, it squeezes the right end of the rotating blocks on both sides. The left end of the rotating block opens and closes to release the fixation of the fan blade. When the fan blade needs to be installed, the protective box on the outer wall of the right side of the fan blade abuts against the connecting block. At this time, the threaded rod inside the connecting block moves the round shaft to the left, and the rotating block contacts and squeezes. The left end of the rotating block is stuck in the slot of the second limiting block on the right end of the fan blade, thus completing the installation. Compared with the traditional disassembly by tools, this device only requires turning the threaded rod to directly replace the damaged fan blade, which greatly improves work efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 2-4 This utility model provides an embodiment of a quantitative mixing device for a fluorine-free water-repellent agent, comprising a main body 1 for the water-repellent agent quantitative mixing device, a placement seat 2 at the top of the main body 1, a pull rod 13 inside the placement seat 2, a first limiting block 11 fixedly connected to one end of the pull rod 13, a feeding hopper 3 on the outer wall of the first limiting block 11, a motor 6 on the top outer wall of the main body 1, a rotating rod 7 at the drive end of the motor 6, a fixing plate 8 fixedly connected to the bottom of the rotating rod 7, and a stirring rod 9 on the top outer wall of the fixing plate 8. A connecting block 17 is fixedly connected to the outer wall of the stirring rod 9. A threaded rod 21 is provided inside the connecting block 17. A round shaft 20 is threadedly connected to the outer wall of the threaded rod 21. A second fixing block 18 is fixedly connected to the outer wall of the connecting block 17. A rotating block 19 is provided inside the second fixing block 18. A second limiting block 16 is provided at the left end of the rotating block 19. A fan blade 14 is fixedly connected to the left outer wall of the second limiting block 16. A protective box 15 is provided on the right outer wall of the fan blade 14. The right outer wall of the protective box 15 is located on the left outer wall of the connecting block 17. The outer wall of the round shaft 20 is located on the outer wall of the rotating block 19.

[0027] Specifically, when using this device, the raw materials for making the fluorine-free water-repellent agent are placed into multiple hoppers 3 at the top of the main body 1 of the water-repellent agent quantitative proportioning device. The hoppers 3 are equipped with metering devices to quantitatively control the required raw materials. When it is necessary to make water-repellent agents with different functions, different types of hoppers 3 need to be replaced. At this time, simply pull the pull rods 13 on both sides of the placement seat 2. The pull rods 13 drive the first limiting block 11 to compress the spring 12. The first limiting block 11 disengages from the middle of the first fixing block 10 on the outer wall of the hopper 3, releasing the position restriction on the hopper 3. At this time, the hopper 3 can be taken out upward along the sliding groove inside the placement seat 2 to complete the disassembly. When a hopper 3 suitable for other raw materials is placed in, the first fixing block 10 on the outer wall of the hopper 3 moves upward along the placement seat. 2. Insert the internal chute, release the pull rod 13, and the spring 12 releases its limit, causing the first limit block 11 to move into the gap between the first fixing block 10 on the outer wall of the lower hopper 3. At this time, the first limit block 11 is attached to the outer wall of the lower hopper 3 and is locked between the first fixing blocks 10. Combined with the placement seat 2, the lower hopper 3 is fully fixed in the up-down and left-right directions to prevent the lower hopper 3 from shifting due to vibration caused by feeding. At this time, the installation of the lower hopper 3 is completed. Compared with the traditional fixed lower hopper 3, which is only suitable for a single raw material, this device can quickly replace the lower hopper 3 to adapt to different materials, thereby meeting diversified production needs. After the raw material is put into the main body 1 of the water-repellent quantitative proportioning device, the motor 6 is started. The motor 6 drives the rotating rod 7 to rotate the connected fixing plate 8. The stirring rod 9 on the fixed plate 8 also rotates, causing the connecting block 17 on the outer wall of the stirring rod 9 to drive the fan blade 14 to rotate, fully stirring the raw materials in the device and ensuring thorough mixing. When the fan blade 14 needs to be replaced, open the cover through the handle on the top of the water-repellent quantitative proportioning device body 1, and take out the fan blade 14 installed on the stirring rod 9. At this time, rotate the threaded rod 21, and the round shaft 20 on the threaded rod 21 moves to the left, releasing the pressure on the bottom right end of the rotating blocks 19 on both sides, causing the left end of the rotating blocks 19 to lift up, thereby releasing the fixation of the second limiting block 16. At this time, pull out the second limiting block 16, taking the connected fan blade 14 away from the fixation of the connecting block 17, and the fan blade 14 can be disassembled. When replacing the new fan blade 14, the outer wall on the right side of the fan blade 14... When the protective box 15 abuts against the connecting block 17, the threaded rod 21 is rotated, and the round shaft 20 moves to the right, pressing the bottom right end of the rotating block 19 located on both sides. This causes the left end of the rotating block 19 to close and lock the second limiting block 16, thus fixing the fan blade 14. This completes the installation of the fan blade 14. After the fan blade 14 is installed, it will bring the protective box 15 to abut against the strip groove of the connecting block 17, so that the round shaft 20, rotating block 19, and round shaft 20 are in the protective box 15. The sealing strip installed on the outer wall of the protective box 15 can better prevent raw materials from penetrating into the rotating block 19 and round shaft 20 and causing blockage, restricting rotation, and also preventing the threaded parts from affecting the stirring of raw materials. The left end of the rotating block 19 is provided with a protrusion, and the top and bottom of the second limiting block 16 are provided with slots.The protruding part of the rotating block 19 is press-fitted into the groove of the second limiting block 16, making it more securely hold the second limiting block 16 in place and preventing the fan blade 14 from detaching due to centrifugal force during stirring.

[0028] Reference Figure 1 , Figure 3 and Figure 5 The outer wall of the hopper 3 is fixedly connected to a first fixing block 10. One end of the spring 12 is set on the outer wall of the first limiting block 11. The stirring rod 9 is provided with a fixing rod 22 inside. The stirring rod 9 is provided with a groove 25 on the outside. The outer wall of the fixing rod 22 is fixedly connected to a locking block 24. The top of the fixing rod 22 is provided with a thread. The threaded outer wall is connected to a nut 23. The outer wall of the water-repellent quantitative proportioning device body 1 is fixedly connected to a placement platform 5. The bottom of the water-repellent quantitative proportioning device body 1 is provided with a discharge port 4.

[0029] Specifically, when the stirring rod 9 is installed on the fixed rod 22, the locking block 24 on the outer wall of the fixed rod 22 and the groove 25 inside the stirring rod 9 fit together. When the fixed rod 22 rotates, the stirring rod 9 on the outside will also rotate due to the action of the locking block 24 and the groove 25, thus preventing it from rotating on its own. The thread and nut 23 on the top of the fixed rod 22 can fix the stirring rod 9 after it is installed on the fixed rod 22, preventing it from coming off when rotating. The placement platform 5 plays a role in fixing the main body 1 of the water-repellent quantitative mixing device. The water-repellent can be taken out through the discharge port 4 after it is made.

[0030] Working principle: When using this device, the raw materials for the fluorine-free water-repellent agent are fed into multiple hoppers 3 at the top of the main body 1 of the water-repellent agent quantitative proportioning device. Each hopper 3 is equipped with a metering device to accurately control the amount of each raw material fed in, ensuring the accuracy of the proportioning. When it is necessary to produce water-repellent agents with different functions, the first limiting block 11 can be disengaged from the slot between the first fixing block 10 on the outer wall of the hopper 3 by pulling the pull rod 13 on both sides of the placement seat 2, thus releasing the locking of the hopper 3. At this time, the hopper 3 can be taken out along the slide groove to replace it with a model suitable for other raw materials. During installation, the first fixing block 10 of the new hopper 3 is placed into the slide groove, the pull rod 13 is released, the spring 12 pushes the first limiting block 11 to reset and lock between the first fixing blocks 10, realizing the quick fixing of the hopper 3. After the raw materials enter the device, the motor 6 is started to drive the rotating rod 7, which drives the fixing plate 8 and the stirring rod 9 to rotate. The connecting block 17 on the stirring rod 9 rotates accordingly, driving the fan blade 14 to fully stir the raw materials and improve the mixing uniformity. If the fan blade 14 needs to be replaced after long-term use, open the top cover of the device and rotate the threaded rod 21. When the round shaft 20 moves to the left to release the pressure on the rotating block 19, the rotating block 19 uses the second fixed block 18 as a fulcrum and uses the lever principle to make the left end tilt up, releasing the clamping of the second limiting block 16. When the threaded rod 21 is rotated in the opposite direction, the round shaft 20 pushes to the right and squeezes the rotating block 19 through the wedge surface, so that the protruding structure at the left end of the rotating block 19 forms a fit with the slot of the second limiting block 16, thereby fixing the fan blade 14. After the fan blade 14 is installed, the protective box 15 on its outer wall fits into the strip groove on the left side of the connecting block 17, protecting the internal threaded parts and preventing the parts from affecting the stirring of the raw materials. The stirring rod 9 cooperates with the groove 25 of the fixed rod 22 through the internal locking block 24 to ensure that it does not rotate during the stirring process. The top nut 23 is threadedly connected to the fixing rod 22, which further reinforces the stirring rod 9 and prevents it from coming off during high-speed rotation. The mixed water-repellent agent is discharged through the discharge port 4 at the bottom of the device, and the placement platform 5 provides stable support for the entire device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
