Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a waterproofing agent combination mixing device. Background Technology

[0002] A waterproofing agent mixing device is a piece of equipment used to mix and stir various waterproofing agent raw materials in a certain proportion to prepare waterproofing agent products with specific properties.

[0003] Chinese patent CN213791494U discloses a waterproofing agent mixing device. The device features a motor mounted on a motor bracket, which is fixedly connected to a base. A bearing seat bracket is also fixedly connected to the base, and a first bearing seat is mounted on the bearing seat bracket. A roller passes through the first bearing seat and is also connected to a drum. One end of the roller is connected to the motor, and the other end is connected to a second bearing seat, which is mounted on the bearing seat bracket. The patent incorporates a flow meter and a switching valve on the feed pipe to effectively control the feed ratio. Filters at the raw material funnel and discharge port effectively address the issue of excessive impurities in the mixed product. The device is highly practical and has significant market potential.

[0004] However, the waterproofing agent combination mixing device disclosed in the above patent still has certain shortcomings in actual use. When mixing, it uses a roller to drive multiple mixing blades to rotate and mix. This single-axis mixing method is inefficient and can only rotate and mix in one direction, making it difficult to achieve uniform mixing, which is inconvenient. In addition, the structure used for mixing, such as the mixing blades, is fixed and cannot be disassembled, making it inconvenient to clean. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproofing agent combination mixing device to solve the problems mentioned in the background art, such as the low efficiency of the existing waterproofing agent combination mixing device using a single-shaft stirring method, the inability to achieve uniform mixing by only rotating and stirring in one direction, and the fixed installation of the stirring structure, which cannot be disassembled and is inconvenient for cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproofing agent combination mixing device, comprising a mixing tank, a mixing disc disposed within the inner cavity of the mixing tank, a rotating shaft rotatably connected between the two side walls of the inner cavity at the center of the mixing disc, a drive gear fixed to the surface of the shaft shaft, a second motor whose output end is connected to the top end of the shaft shaft fixed to the top wall of the mixing tank, and four rotating rods arranged in a circumferential array outside the rotating shaft, the bottom end of the rotating rod penetrating the bottom wall of the mixing tank via a bearing, and the top end of the rotating rod being fixed to the surface of the shaft shaft. The rotating rod has a driven gear that meshes with the driving gear. A connecting cavity is formed in the bottom wall of the rotating rod. A connecting column is connected in the cavity. A positioning hole is formed on the surface of the connecting column. A mixing rod is fixed at the bottom end of the connecting column. A positioning component is provided on the bottom circumferential side wall of the rotating rod. A connecting frame is fixed on the top wall of the mixing disc. A driving rod is fixed on the top wall of the connecting frame. The top end of the driving rod passes through the top wall of the mixing box via a bearing. A first motor is fixed on the top wall of the mixing box. The output end of the first motor is connected to the top end of the driving rod.

[0007] Preferably, the positioning component includes a positioning block fixedly installed on the circumferential side wall of the rotating rod. The positioning block has a cavity inside, and a movable rod is provided in the cavity. One end of the movable rod movably passes through one side wall of the cavity and extends into the cavity of the connecting cavity. The rod can be inserted into the cavity of the positioning hole.

[0008] Preferably, the other end of the movable rod extends through the other side wall of the cavity, and a lever is fixedly installed at the end of the movable rod away from the connecting cavity. The positioning assembly also includes a fixing block and a spring disposed in the cavity. The fixing block is fixedly sleeved on the surface of the movable rod, and the spring is sleeved on the surface of the movable rod, with the spring located on the side of the fixing block away from the connecting cavity.

[0009] Preferably, the top wall of the mixing box is equipped with multiple feeding hoppers.

[0010] Preferably, two symmetrically distributed connecting rods are fixedly installed on the circumferential sidewall of the mixing disc, and scrapers are fixedly installed at the ends of the connecting rods, with the outer sidewall of the scrapers in contact with the inner wall of the mixing box.

[0011] Preferably, the surface of the mixing rod is uniformly and fixedly covered with multiple protruding columns.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a first motor to drive a drive rod to rotate. Since the drive rod is fixedly installed with the connecting frame, the drive rod drives the mixing disc to rotate, which in turn causes the four mixing rods at the bottom of the mixing disc to revolve around the drive rod. Under the action of a second motor, the second motor drives a rotating shaft to rotate. The rotating shaft rotates the drive gear, which in turn drives the driven gear, which in turn drives the rotating rod to rotate. The rotating rod then drives the mixing rods fixed at the bottom of the rotating rod to rotate on their own axis. Thus, the revolution and rotation of the mixing rods can be achieved under the action of the first and second motors, and the direction of rotation can be controlled. This multi-axis rotational mixing is achieved under the action of the four mixing rods, which helps to improve the mixing efficiency and makes the waterproofing agent more evenly mixed.

[0014] This invention, by incorporating a positioning component, allows for easy removal of the mixing rod for cleaning. Simply move the movable rod via a lever, causing it to disengage from the positioning hole on the connecting column. Once disengaged, the connecting column can be quickly removed from the connecting cavity, facilitating cleaning of the mixing rod. Furthermore, the movement of the movable rod from the positioning hole causes the fixing block to compress the spring. Releasing the lever allows the movable rod to automatically return to its original position under the spring's action. When reinstalling the mixing rod, simply pull the movable rod again to remove it from the connecting cavity. After the connecting column is inserted into the cavity, releasing the movable rod allows it to automatically insert into the positioning hole on the connecting column, completing the installation and fixing of the mixing rod. This convenient design avoids the inconvenience of disassembling and cleaning the mixing structure found in existing mixing devices. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a waterproofing agent combination mixing device, including a mixing box 1, a mixing disc 4 disposed in the inner cavity of the mixing box 1, a rotating shaft 22 rotatably connected to the upper and lower side walls of the inner cavity of the mixing disc 4 at the center via bearings, and a drive gear 23 welded to the shaft surface of the rotating shaft 22, the purpose of which is to drive the drive gear 23 to rotate together when the rotating shaft 22 rotates. A second motor 6 is fixed to the top wall of the mixing disc 4 by screws, the output end of which is connected to the top end of the shaft of the rotating shaft 22. The second motor 6 is connected to the rotating shaft 22 via a coupling, so that the second motor 6 can drive the rotating shaft 22 to rotate, thereby driving the drive gear 23 to rotate. Four rotating rods 10 arranged in a circular array are disposed outside the rotating shaft 22. The bottom end of each rotating rod 10 passes through the bottom wall of the mixing disc 4 via a bearing. A driven gear 24, which meshes with the driving gear 23, is welded to the top surface of the rotating rod 10. The purpose of this is to allow the driving gear 23 to rotate, thereby causing the driven gear 24 to rotate as well, which in turn causes the rotating rod 10 to rotate. A connecting cavity 15 is formed in the bottom wall of the rotating rod 10, and a connecting post 13 is connected to the cavity of the connecting cavity 15. The two are detachably connected. A positioning hole 14 is formed on the surface of the connecting post 13. A mixing rod 11 is welded to the bottom end of the connecting post 13. A positioning component is provided on the bottom circumferential side wall of the rotating rod 10. The positioning component facilitates the removal of the connecting post 13 along with the mixing rod 11 from the rotating rod 10, thereby facilitating the cleaning of the mixing rod 11. The connecting frame 5 is welded to the top wall of the mixing tray 4, and the drive rod 7 is welded to the top wall of the connecting frame 5. The top rod of the drive rod 7 passes through the top wall of the mixing box 1 via a bearing. The top wall of the mixing box 1 is fixed with a first motor 2 by screws. The output end of the first motor 2 is connected to the top rod of the drive rod 7 via a coupling.

[0022] The positioning assembly includes a positioning block 16 welded to the circumferential sidewall of the rotating rod 10. A cavity 17 is formed inside the positioning block 16. A movable rod 18 is disposed in the inner cavity of the cavity 17. One end of the movable rod 18 movably penetrates one sidewall of the cavity 17 and extends into the cavity of the connecting cavity 15. The rod of the movable rod 18 can be inserted into the cavity of the positioning hole 14, so that when the movable rod 18 is inserted into the positioning hole 14, the connecting post 13 can be stably installed in the connecting cavity 15. The other end of the movable rod 18 movably penetrates the other sidewall of the inner cavity of the cavity 17. A lever 21 is welded to the end of the movable rod 18 away from the connecting cavity 15. The purpose of the lever 21 is to facilitate the movement of the movable rod 18. The positioning assembly also includes a fixing block 19 and a spring 20 disposed in the cavity 17. The fixing block 19 is welded and sleeved on the surface of the movable rod 18, and the spring 20 is sleeved on the surface of the movable rod 18. The spring 20 is located on the side of the fixing block 19 away from the connecting cavity 15, so that the movable rod 18 can be automatically reset. Multiple feeding hoppers 3 are installed on the top wall of the mixing box 1 to facilitate the addition of waterproofing agent raw materials into the mixing box 1. Two symmetrically distributed connecting rods 8 are welded to the circumferential side wall of the mixing disc 4. A scraper 9 is welded to the end of the connecting rod 8. The outer side wall of the scraper 9 is in contact with the inner wall of the mixing box 1, so that when the mixing disc 4 rotates, it can drive the scraper 9 to rotate together, thereby allowing the scraper 9 to scrape the raw materials off the inner wall of the mixing box 1. Multiple protruding columns 12 are uniformly welded to the cylindrical surface of the mixing rod 11, which is used to improve the mixing capacity.

[0023] In use, the first motor 2 drives the drive rod 7 to rotate. Since the drive rod 7 and the connecting frame 5 are fixedly installed, the drive rod 7 drives the mixing disc 4 to rotate, thereby causing the four mixing rods 11 at the bottom of the mixing disc 4 to revolve around the drive rod 7. Under the action of the second motor 6, the second motor 6 drives the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 drives the drive gear 23 to rotate, which in turn drives the driven gear 24 to rotate. The driven gear 24 drives the rotating rod 10 to rotate, which in turn drives the mixing rods 11 fixed at the bottom of the rotating rod 10 to rotate on their own axis. Thus, under the action of the first motor 2 and the second motor 6, the mixing rods 11 can revolve and rotate on their own axis, and the direction of rotation can be controlled. This multi-axis rotation and mixing is achieved under the action of the four mixing rods 11, which helps to improve the mixing efficiency and make the waterproofing agent more evenly mixed. By setting a positioning component, the mixing rods can be removed when needed. When cleaning the mixing rod 11, simply move the movable rod 18 by using the lever 21 to pull it out of the positioning hole 14 on the surface of the connecting column 13. After the movable rod 18 is pulled out, the connecting column 13 can be quickly removed from the connecting cavity 15, making it easy to clean the mixing rod 11. During the process of the movable rod 18 being pulled out of the positioning hole 14, the fixing block 19 will compress the spring 20, so that after releasing the lever 21, the movable rod 18 can automatically return to its original position under the action of the spring 20. Therefore, when it is necessary to reinstall the mixing rod 11, pull the movable rod 18 again to pull it out of the connecting cavity 15. After the connecting column 13 is inserted into the connecting cavity 15, release the movable rod 18, and it will automatically insert into the positioning hole 14 on the surface of the connecting column 13, completing the installation and fixing of the mixing rod 11. This is very convenient and avoids the situation where the existing mixing device is not convenient for disassembling and cleaning the mixing structure.
