Description

Technical Field

[0001] This utility model relates to the technical field of powder mixing equipment, and in particular to a powder mixing equipment that is easy to clean. Background Technology

[0002] In industries such as chemical, building materials, and food processing, powder mixing equipment is a key piece of equipment for achieving uniform mixing of various materials. Its operational stability and ease of cleaning directly affect product quality and production efficiency. Currently, most powder mixing equipment on the market uses an auger as the core mixing component. The spiral structure of the auger drives the powder to tumble and mix. Although this can meet basic mixing requirements, it has obvious shortcomings in actual use.

[0003] On the one hand, the mixing chamber and auger of existing equipment are mostly fixedly connected or have complex disassembly and assembly structures. The angle of the mixing chamber cannot be flexibly adjusted, which makes it easy for a large amount of powder to remain in the corners of the equipment and at the connection between the auger and the shaft. This makes it difficult to achieve thorough cleaning in all directions, which not only affects the purity of subsequent mixing of different materials, but also requires a lot of manpower and time to clean, resulting in extremely low cleaning convenience and efficiency.

[0004] On the other hand, the spiral blade structure of the auger itself has inherent cleaning dead zones. Powder is easily attached to the blade roots, spiral gaps and the connection points with the connecting parts. Moreover, the existing auger installation structure mostly relies on traditional fixing methods such as bolts and clips, and the disassembly and assembly process is cumbersome, which further increases the difficulty of cleaning. This leads to the long-term accumulation of residual powder, which not only affects the service life of the equipment, but also poses hygiene and safety hazards. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems in the prior art, such as the inability to flexibly adjust the angle of the mixing chamber, making it difficult to achieve thorough cleaning in all directions, and the inherent cleaning dead angles of the spiral blade structure of the auger itself.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a powder mixing device that is easy to clean: including a bottom support plate, wherein two support legs are fixedly connected to the upper surface of the bottom support plate, and further including: The mixing dish is rotatably connected to the upper end of the two support legs via bearings; An adjustment mechanism is provided on one side of a support leg, including a bevel gear. A fixed plate is rotatably connected to one side surface of the bevel gear via a rotating shaft. One side surface of the fixed plate is fixed to the outer surface of the support leg. A locking mechanism is provided on the upper surface of the bottom support plate, including a sleeve fixed to the upper surface of the bottom support plate, wherein a sliding tube is slidably embedded inside the sleeve; The rotating rod is rotatably connected to the bottom of the inner wall of the mixing dish via a bearing; The mounting slot is located at the upper end of the rotating rod; The connecting mechanism is located inside the mounting slot; The motor is fixed to the lower surface of the mixing dish, and its output end is fixed to the lower end of the rotating rod; The auger is installed on the outer surface of the rotating rod.

[0007] In a preferred embodiment, the locking mechanism further includes: Support arm, fixed to the upper end of the sliding tube; The connecting block is rotatably connected to one end of the support arm via a bearing. The lower end of the connecting block is embedded inside the mounting groove.

[0009] In a preferred embodiment, the adjustment mechanism further includes: The second bevel gear is fixed to one end of the rotating shaft of the rotating support leg of the mixing dish; The adjusting disc is fixed to one end of the rotating shaft on one side of the bevel gear; Among them, the teeth of bevel gear two mesh with the teeth of bevel gear one.

[0010] In a preferred embodiment, the connecting mechanism includes: Linkage 1 is rotatably connected to the inner wall of the mounting slot; Link 2 is rotatably connected to one end of link 1; The slider is rotatably connected to one end of connecting rod two. There are two top plates, one fixed to one side of the slider and the other fixed to the bottom of the inner wall of the mounting groove; Spring 2 is fixed to the opposite surfaces of the two top plates; Through holes are formed inside the mounting slot; The outer surface of the slider is embedded inside the mounting groove; The connecting pipe is sleeved on the outer surface of the rotating rod and fixed inside the auger; A connecting groove is formed inside the connecting pipe; One end of the slider is embedded inside the connecting groove.

[0011] In a preferred embodiment, the connecting mechanism further includes: The positioning block is fixed to the outer surface of the rotating rod; A positioning groove is provided at the lower end of the connecting pipe; The outer surface of the positioning block is embedded inside the positioning groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In use, rotating the adjustment disc drives the first bevel gear to rotate, which in turn drives the mixing dish to rotate around the upper end of the support leg via the second bevel gear. This pushes the push rod to compress the first spring of the connecting plate, causing the locking block to disengage from the groove on the inner wall of the sleeve, and then slides the sliding tube. The support arm drives the connecting block to disengage from the mounting groove of the rotating rod, releasing the auxiliary fixation on the rotating rod. The adjustable angle of the mixing dish allows for all-round cleaning of residual powder inside, greatly improving cleaning convenience and efficiency. Furthermore, the cooperation of each locking mechanism and connecting mechanism ensures the stable operation of the equipment and ensures accurate and reliable mixing.

[0013] 2. In use, when installing the auger, first place the connecting pipe on the outer surface of the rotating rod, so that the positioning block on the rotating rod is accurately embedded in the positioning groove at the lower end of the connecting pipe. The lower end of the connecting block presses against connecting rod one and connecting rod two, allowing one end of the slider to pass through the through hole and be embedded in the connecting groove of the connecting pipe, thus achieving a stable lock. When disassembling and cleaning, the connecting block is disengaged from the mounting groove, and spring two pushes the slider to disengage from the connecting groove, allowing the auger and connecting pipe to be quickly removed. With the guidance of the positioning block and the positioning groove, the ease of disassembly and assembly and the accuracy of reassembly are improved, effectively reducing the cleaning dead zones of residual powder inside the equipment and improving the cleaning effect.

[0026] Working principle: When in use, first put the powder to be mixed into the mixing dish 3, start the motor 11, the output end of the motor 11 drives the rotating rod 13 to rotate, the rotating rod 13 drives the auger 7 to rotate synchronously through the connecting mechanism, and the spiral structure of the auger 7 is used to efficiently mix the powder. During cleaning, push the push rod 9 to drive the connecting plate 14 to compress the spring 16, so that the locking block 15 is disengaged from the groove on the inner wall of the sleeve 8, and the sliding tube 10 slides up and down to drive the connecting block 5 to disengage from the mounting groove 20 of the rotating rod 13 through the support arm 6, releasing the auxiliary fixation of the rotating rod 13. Rotate the adjusting plate 12 to drive the bevel gear 18 to rotate. Through the meshing transmission of the bevel gear 18 and the bevel gear 2 19, drive the mixing dish 3 to rotate around the bearing at the upper end of the support leg 2, and adjust to a suitable tilt angle.

[0027] In use, first, the auger 7 is fitted onto the outer surface of the rotating rod 13 through the connecting pipe 4. The positioning block 29 on the rotating rod 13 is embedded into the positioning groove 28 of the connecting pipe 4, completing the initial positioning of the auger 7 and the rotating rod 13. Then, the connecting block 5 is embedded into the mounting groove 20 of the rotating rod 13. The connecting block 5 presses the connecting rod 1 23 and the connecting rod 24 together, pushing the slider 21 through the through hole 25 and embedding it into the connecting groove 22 of the connecting pipe 4, thus achieving a stable lock between the auger 7 and the rotating rod 13. The motor 11 is started, and the rotating rod 13 drives the auger 7 to rotate for powder mixing. During the mixing process, the locking mechanism keeps the connecting block 5 fixed through components such as the locking block 15 and the spring 16, ensuring stable transmission. When cleaning, push the push rod 9 to make the connecting block 5 disengage from the mounting groove 20. The spring 26 pushes the slider 21 to reset through the top plate 27.
