Description

Technical Field

[0001] This utility model belongs to the field of cream production technology, and in particular relates to an anti-settling stirring device for cream production. Background Technology

[0002] Creams are typically composed of a multiphase mixture of oil, water, active ingredients, fillers, and stabilizers. During the production of creams, a stirring device is required to mix the various components evenly.

[0003] However, existing stirring devices for cream production still have significant shortcomings in practical applications. They struggle to achieve uniform dispersion of components without stratification or sedimentation. Localized sedimentation easily occurs during stirring, leading not only to uneven content of active ingredients in the cream but also potentially causing a grainy texture and clumping, directly impacting the user experience and efficacy of the product. Therefore, there is an urgent need to improve upon existing devices and provide an anti-sedimentation stirring device for cream production. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reasonably designed, simple structure, anti-sedimentation, and fully mixing stirring device for cream production, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sedimentation prevention stirring device for cream production, comprising: A mixing tank, wherein a vertical tube is mounted on the inner bearing in the middle of the mixing tank, and a drive mechanism for controlling its rotation is provided on the outer side of the top end of the vertical tube; A support bracket is fixedly installed at the rear upper part of the mixing tank. A second motor is fixed at the top of the support bracket. A reciprocating screw is fixed at the output end of the second motor. The bottom end of the reciprocating screw is rotatably installed on the upper end face of the mixing tank. A screw sleeve is fitted on the outer side of the reciprocating screw. A crossbar is fixed on the outer wall of the front of the screw sleeve. The limiting component and the push rod are provided. The limiting component is fixed to the inner wall of the top end of the vertical tube. The push rod includes a square segment and a cylindrical segment located at the top end of the square segment. The square segment of the push rod is engaged and slidably connected with the limiting component. The cylindrical segment of the push rod is connected to the bearing of the horizontal bar. A piston block is fixed to the bottom end of the push rod, and the piston block is located in a sealed sliding position inside the vertical tube.

[0006] Preferably, the bottom of the mixing tank has a funnel-shaped structure, and multiple support legs are fixed in a ring on its bottom surface. The top of the mixing tank has a feed inlet, and a discharge pipe is fixedly connected to the left side wall of its bottom. A solenoid valve for controlling the opening and closing of the discharge pipe is installed on the discharge pipe.

[0007] Preferably, the driving mechanism includes a first bevel gear, a first motor, and a second bevel gear. The first bevel gear is fixedly sleeved on the outer side of the top end of the vertical pipe, the first motor is fixedly mounted on the top right end of the mixing tank, and the second bevel gear is fixedly mounted on the output shaft of the first motor, and the second bevel gear meshes with the first bevel gear.

[0008] Preferably, the upper outer wall of the vertical tube has several windows arranged in a ring around its own vertical axis.

[0009] Preferably, the system also includes a wall-scraping stirring mechanism, which includes a first stirring rod, a second stirring rod, and a rubber scraper. The first stirring rod is arranged horizontally and its two ends are fixedly connected to the vertical pipe and the second stirring rod, respectively. The second stirring rod is arranged in a zigzag shape and a rubber scraper is embedded in its outer surface. The rubber scraper slides in contact with the inner surface of the mixing tank.

[0010] Preferably, a receiving groove is provided at the bottom center of both the piston block and the vertical tube, and an injection port is provided below the receiving groove. The diameter of the receiving groove is larger than the diameter of the injection port, and a protrusion is provided on the top left inner wall of the receiving groove.

[0011] Preferably, the storage slot is hinged with a cover, the cover has a rotation range of 0-60°, and a sealing gasket is adhered to the inner bottom surface of the storage slot.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by starting the second motor and utilizing the reciprocating screw and its sleeve, the crossbar can be stably driven to move the push rod and piston block in a reciprocating lifting motion. When the piston block rises vertically from the bottom of the vertical tube, the cap at the center of the bottom of the vertical tube opens under suction, while the cap at the center of the piston block remains closed under suction. This efficiently draws material from the bottom of the mixing tank into the vertical tube. When the piston block moves downward, the cap at the center of the bottom of the vertical tube closes tightly under thrust, while the cap at the center of the piston block opens under thrust, allowing material to be squeezed above the piston block. As the piston block rises again, the material can be discharged through the window and flow back into the mixing tank. This structural design reliably achieves the circulation and transport of material from the bottom to the top, effectively preventing material deposition at the bottom of the mixing tank, significantly improving the uniformity and sufficiency of the mixing of each component, and thus ensuring the quality of the mixed material.

[0013] After the first motor is started, the vertical tube can be controlled to rotate at a uniform speed under the transmission cooperation of the meshing first and second bevel teeth. The first and second stirring rods thoroughly mix the materials, ensuring the stability and uniformity of the mixing process. At the same time, during the rotation and mixing process, the rubber scraper on the outer surface of the second stirring rod can continuously and closely scrape the inner wall of the mixing tank, effectively preventing materials from adhering to the tank wall, reducing the deviation in the mixing ratio caused by material residue, and further ensuring the consistency and reliability of the material mixing effect.

[0016] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings: like Figure 1-5 As shown in one example, the anti-sedimentation stirring device for cream production of this utility model includes: A mixing tank 1 has a vertical pipe 5 mounted on the inner bearing in the middle of the mixing tank 1, and a drive mechanism for controlling its rotation is provided on the outer side of the top of the vertical pipe 5. The support 9 is fixedly installed at the rear upper part of the mixing tank 1. The top of the support 9 is fixed with a second motor 10. The output end of the second motor 10 is fixed with a reciprocating screw 11. The bottom end of the reciprocating screw 11 is rotatably installed on the upper end face of the mixing tank 1. A screw sleeve 12 is sleeved on the outside of the reciprocating screw 11. A crossbar 13 is fixed on the outer wall in front of the screw sleeve 12. The limiting member 18 and the push rod 19 are fixed to the inner wall of the top end of the vertical tube 5. The push rod 19 includes a square section and a cylindrical section located at the top of the square section. The square section of the push rod 19 is engaged and slidably connected with the limiting member 18. The cylindrical section of the push rod 19 is connected to the horizontal bar 13 by a bearing. Piston block 20 is fixed to the bottom end of push rod 19, and piston block 20 is located in a sealed sliding position inside vertical tube 5.

[0017] As a preferred embodiment, based on the above structure, the bottom of the mixing tank 1 is funnel-shaped, and multiple support legs 2 are fixed in a ring on its bottom surface. The top of the mixing tank 1 is provided with a feed inlet, and a discharge pipe 3 is fixedly connected to the left side wall of its bottom. A solenoid valve 4 for controlling its opening and closing is installed on the discharge pipe 3.

[0018] In this embodiment, the discharge pipe 3 is designed to facilitate the discharge of fully mixed materials, and the opening and closing of the discharge pipe 3 is easily controlled by the solenoid valve 4.

[0019] As a preferred embodiment, based on the above structure, the driving mechanism further includes a first bevel gear 6, a first motor 7, and a second bevel gear 8. The first bevel gear 6 is fixedly sleeved on the outer side of the top end of the vertical pipe 5, the first motor 7 is fixedly mounted on the top right end of the mixing tank 1, and the second bevel gear 8 is fixedly mounted on the output shaft of the first motor 7, and the second bevel gear 8 meshes with the first bevel gear 6.

[0020] In this embodiment, when the first motor 7 is started to control the rotation of the second bevel tooth 8, the first bevel tooth 6, which meshes with the second bevel tooth 8, is used to facilitate the control of the rotation of the vertical pipe 5.

[0021] As a preferred embodiment, based on the above structure, the upper outer wall of the vertical tube 5 is further provided with a number of windows 14 in a ring around its own vertical axis, and when the piston block 20 rises to the highest position, its upper surface and the inner bottom surface of the window 14 are on the same plane.

[0022] In this embodiment, the window 14 opened on the outer wall of the upper end of the vertical pipe 5 facilitates the return of the subsequently extracted material to the mixing tank 1.

[0023] As a preferred embodiment, based on the above structure, it further includes a wall-scraping stirring mechanism, which includes a first stirring rod 15, a second stirring rod 16 and a rubber scraper 17. The first stirring rod 15 is arranged horizontally and its two ends are fixedly connected to the vertical pipe 5 and the second stirring rod 16 respectively. The second stirring rod 16 is arranged in a zigzag shape and the rubber scraper 17 is embedded and fixed on its outer surface. The rubber scraper 17 slides in contact with the inner surface of the mixing tank 1.

[0024] In this embodiment, during the rotary stirring process, the rubber scraper 17 on the outer surface of the second stirring rod 16 can form a continuous and close scraping action on the inner wall of the mixing tank 1, which effectively prevents the material from adhering to the tank wall and reduces the mixing ratio deviation caused by material residue.

[0025] As a preferred embodiment, based on the above structure, a receiving groove 21 is further provided at the bottom center of both the piston block 20 and the vertical tube 5, and an injection port 22 is provided below the receiving groove 21. The diameter of the receiving groove 21 is larger than the diameter of the injection port 22, and a protrusion is provided on the upper left inner wall of the receiving groove 21.

[0026] In this embodiment, the protrusion on the top left side wall of the storage slot 21 can limit the rotation range of the cover 23, preventing it from rotating excessively and failing to close.

[0027] As a preferred embodiment, based on the above structure, a cover 23 is hinged inside the storage groove 21, the rotation range of the cover 23 is 0-60°, and a sealing gasket 24 is adhered to the inner bottom surface of the storage groove 21.

[0028] In this embodiment, the sealing gasket 24 facilitates an effective seal between the cap 23 and the injection port 22, preventing leakage that could affect the material suction and circulation effect.

[0029] The working principle of this utility model is as follows: In use, the components are first added into the mixing tank 1 through the feed port at the upper left of the mixing tank 1. Then, the first motor 7 is started to control the first bevel tooth 6 to rotate. At this time, the second bevel tooth 8, which meshes with the first bevel tooth 6, can control the vertical tube 5 to drive the first stirring rod 15 and the second stirring rod 16 to rotate at a uniform speed, so as to achieve the mixing of the components. During the mixing process, the second motor 10 is started. Utilizing the reciprocating screw 11 and screw sleeve 12, it stably drives the crossbar 13 to reciprocate and lift the push rod 19 and piston block 20. When the piston block 20 rises from the bottom of the vertical pipe 5, the cap 23 at the center of the bottom of the vertical pipe 5 opens under suction, while the cap 23 at the center of the piston block 20 remains closed under suction. At this time, the material at the bottom of the mixing tank 1 can be efficiently drawn into the vertical pipe 5 through the inlet 22. When the control... When the piston block 20 moves down, the cover 23 at the center of the bottom end of the vertical pipe 5 closes tightly under the action of thrust, while the cover 23 at the center of the piston block 20 opens under the action of thrust, allowing the material to be squeezed into the upper part of the piston block 20. As the piston block 20 rises again, the material can be discharged through the window 14 and flow back into the mixing tank 1, thereby realizing the circulation of the bottom material to the top, effectively avoiding the deposition of material at the bottom of the mixing tank 1, significantly improving the uniformity and fullness of the mixing of each component material, and thus ensuring the quality of material mixing. In addition, during the rotary stirring process, the rubber scraper 17 on the outer surface of the second stirring rod 16 can form a continuous and close scraping action on the inner wall of the mixing tank 1, which effectively prevents the material from adhering to the tank wall, reduces the mixing ratio deviation caused by material residue, and further ensures the consistency and reliability of the material mixing effect. It should be noted that this device is powered by an external power source. The solenoid valve 4, the first motor 7, and the second motor 10 in this solution are all existing electrical components equipped with corresponding controllers. Their specific control principles and methods are all mature existing technologies. In addition, the reciprocating screw 11 and the screw sleeve 12 in this solution are also common and widely used existing transmission mechanisms, which are directly referenced in this case and will not be described in detail.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
