Description

Technical Field

[0001] This utility model relates to the field of cream production and processing technology, specifically a pretreatment device for cosmetic cream raw materials. Background Technology

[0002] In cosmetic production, the pretreatment of ointment raw materials is particularly crucial, directly affecting the texture, stability, and user experience of the final product. These raw materials generally have characteristics such as high viscosity, easy layering, or clumping. Efficient mixing and homogenization pretreatment is the foundation for ensuring the quality of subsequent emulsification and filling.

[0003] Currently, the industry commonly uses multi-stage mixing or complex mechanical devices for raw material pretreatment. Existing technologies rely on multiple independently driven agitators or dispersing discs for mixing, resulting in high energy consumption due to the equipment's structure and drive system. Furthermore, conventional mixing of cosmetic cream raw materials often creates mixing dead zones, leading to unsatisfactory homogenization and potentially causing incomplete blending or clumping of raw materials in certain areas. This reduces pretreatment efficiency, and the high energy consumption of multi-drive equipment further increases production costs, resulting in poor mixing performance and high energy consumption. Utility Model Content

[0004] The purpose of this invention is to design a cosmetic ointment raw material pretreatment device that improves the mixing effect of pretreatment and effectively reduces the use of driving equipment to reduce energy consumption.

[0005] This utility model includes a mixing tank with a stirring mechanism. The stirring mechanism includes a main shaft and a stirring rod mounted on the main shaft. A discharge port is provided at the lower rear end of the mixing tank, and a feeding mechanism is provided on the front end face of the mixing tank. The feeding mechanism includes a feeding hopper and a feeding cylinder whose front end is connected to the feeding hopper and whose rear end is connected to the mixing tank. A spiral belt mounted on the feeding shaft is provided inside the feeding cylinder. The feeding shaft is coaxial with the main shaft and fixedly connected to it.

[0006] Furthermore, the feed shaft is a hollow tube, with a vacuum port with a one-way valve at one end inside the mixing tank, and the other end of the feed shaft extends out of the feeding mechanism, with a solenoid valve for controlling the vacuum operation installed on the extending part.

[0007] Furthermore, a connecting pipe is provided at the inlet end of the feed cylinder; the upper part of the feed hopper is bucket-shaped, and the lower part is a straight cylinder adapted to the shape of the connecting pipe and inserted into the connecting pipe; the upper end of the connecting pipe and the middle part of the feed hopper have matching flanges, which are connected by studs, and a sealing ring is provided between the flanges; a sealing cover plate is provided at the upper port of the feed hopper, and at least one feed pipe is fixed on the sealing cover plate.

[0008] Furthermore, a motor is provided at one end of the mixing tank, the motor shaft is connected to the main shaft, and a transmission mechanism is also provided on the motor shaft; the mixing tank includes an end cover with a feed cylinder and a tank body that is sealed to the end cover and rotatably engaged, a toothed ring is surrounded on the tank body, and a gear connected to the transmission mechanism meshes with the toothed ring.

[0009] Furthermore, the mixing tank includes an inner tank body with a toothed ring on its circumference; one end of the inner tank body is open, and the open end is sealed and rotatably connected to the inner surface of the end cap; an outer tank body with openings at both ends is provided outside the inner tank body, and one end of the outer tank body is fixedly connected to the outer surface of the end cap; a heat exchange pipe is provided between the inner tank body and the outer tank body; a groove corresponding to the toothed ring on the inner tank body is provided at the upper end of the outer tank body; a gear shaft connected to the motor shaft through a transmission mechanism is provided above the outer tank body, and a gear passing through the groove on the outer tank body and meshing with the toothed ring is provided on it.

[0010] Furthermore, protective covers are provided around the gears, gear shafts, and transmission mechanism.

[0011] Furthermore, the rear end of the inner tank is funnel-shaped and extends to the discharge port.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a spiral belt inside the feeding cylinder to shear and push the raw materials, which can achieve the crushing and dispersing of the raw materials and improve the subsequent mixing and homogenization process. At the same time, the inner wall of the mixing tank is integrally provided with dispersing protrusions. By rotating the inner tank and the stirring rod in opposite directions, the mixing effect of the pretreatment can be improved. The motor drives the main shaft and the transmission mechanism to rotate simultaneously. The main shaft can drive the spiral belt and the stirring rod to rotate at the same time. The transmission mechanism drives the inner tank to rotate by meshing the gear on the gear shaft with the gear ring on the outer wall of the inner tank.

The ball bearing 604 cooperates with the corresponding groove 503 on the inner end face of the end cap 5, thereby ensuring smooth rotation between the inner tank and the end cap and preventing friction.

[0024] Toothed rings 601 are respectively provided at both ends of the outer surface of the inner tank 6. The toothed rings 601 at the front and rear ends of the inner tank 6 are at a certain distance from the front and rear edges, respectively, to provide support points for the inner tank 6. The distance between the toothed ring 601 at the front end and the front edge is greater than the distance between the toothed ring 601 at the rear end and the rear edge, to ensure that the front end fits with the end cap 5. The discharge port 15 at the lower rear end of the inner tank 6 is fixedly provided with a discharge pipe 603 with a solenoid valve. The discharge pipe 603 is located in the inner cavity of the outer tank 7 and does not hinder the rotation of the inner tank 6 when it rotates.

[0028] The gear 13 and gear shaft 1301 are integrally formed or welded together, and the meshing of the two gears 13 and the gear ring 601 is absolutely symmetrical. The rigid connection between the gear 13 and gear shaft 1301 ensures synchronous rotation speed. The gear shaft 1301 of appropriate size and dimensions is selected according to the size of the inner tank 6, so that the journal can use the maximum diameter within the space. The shaft length of the gear shaft is shortened as much as possible to reduce the cantilever length, and high rigidity materials (such as alloy steel) are selected to eliminate dynamic phase difference and steady-state torsional angle deviation, thereby ensuring stable drive.

[0029] Two pairs of support plates 701 are respectively provided at the front and rear ends of the lower inner wall of the outer tank 7 and on the opposite side of the toothed ring 601 on the inner tank 6, and the two pairs of support plates 701 are symmetrically arranged on both sides of the axial direction of the inner tank 6; a roller 702 is installed between each pair of support plates 701, and the axis of the roller 702 is parallel to the axis of the inner tank 6, and the surface of the roller 702 contacts and engages with the outer circumferential surface of the inner tank 6, supporting the inner tank 6 inside the outer tank 7.

The protective cover 14 is L-shaped and, together with the vertical plate 704 on the outer tank 7, wraps the gear 13, gear shaft 1301 and transmission mechanism 4, which plays a protective role and further realizes the sealing of the inner tank 6, realizing functions such as heat preservation.

[0032] In this embodiment, a motor support frame 1401 is provided on the outer side of the protective cover 14 at the rear end of the outer tank 7. The motor 12 is fixedly mounted on the motor support frame 1401. The motor shaft 1201 of the motor 12 faces the front end of the mixing tank 1 and is coaxial with the inner tank 6. The motor shaft 1201 is fixedly connected to the main shaft 201 of the stirring mechanism 2 through a coupling 20.

The inner wall of the inner tank 6 is provided with dispersing protrusions 602, and the inner tank 6 and the stirring mechanism 2 rotate in opposite directions under the drive of the motor 12 and the transmission mechanism 4, thereby improving the mixing effect of the pretreatment.

[0034] In this embodiment, a feeding mechanism 3 is provided on the front end face of the mixing tank 1. The feeding mechanism 3 includes a feeding hopper 8 and a feeding cylinder 9 that is connected to the feeding hopper 8 at the front end and to the mixing tank 1 at the rear end. A spiral belt 902 is provided inside the feeding cylinder 9 and mounted on the feeding shaft 901. The feeding shaft 901 is coaxial with the main shaft 201 and is fixedly connected to each other.

[0035] The feeding cylinder 9 includes a feeding shaft 901 and a spiral belt 902 mounted on the feeding shaft 901. It is mounted on the end cover 5 at the front end of the mixing tank 1 and is fixedly connected by a flange. A sealing gasket 501 is provided at the rear end of the feeding cylinder 9 where it meets the end cover 5. The feeding shaft 901 is located inside the feeding cylinder 9. One end extends out of the front end of the feeding cylinder 9 and is sealed to its front end face by a bearing. The other end extends into the inner tank body 6 of the mixing tank 1 and is welded and fixed to the main shaft 201 or integrally formed out. The feeding shaft 901 is a hollow tube. One end of the feeding shaft 901 inside the mixing tank 1 is provided with a suction port 904 equipped with a one-way valve 903. The other end of the feeding shaft 901 extends out of the feeding mechanism 3, and a solenoid valve 905 for controlling the vacuum operation is provided on its extending portion. This enables vacuum operation inside the mixing tank 1, effectively improving the fineness, stability, and sterility of the paste raw materials, and ensuring processing quality.

[0036] The port of the air extraction hole 904 of the feed shaft 901 is inclined toward the rear end of the mixing tank 1 and is equipped with a one-way valve 903 to prevent raw materials from falling into the air extraction hole 904 when the inner tank 1 rotates; and a spiral belt 902 adapted to the diameter of the inner cavity of the feed cylinder 9 is provided on the circumferential surface of the feed shaft 901.

At least one feed pipe 802 is fixed on the sealing cover 801. The feed pipe 802 is equipped with a solenoid valve at the upper end of the sealing cover 801 to control the opening and closing of the feed pipe 802.

[0039] In this embodiment, the solenoid valve 905 at the front end of the feed shaft 901 is first opened to evacuate the inner tank 6 of the mixing tank 1. Then, the solenoid valves of the motor 12 and the feed pipe 802 are opened to allow the raw materials to enter the feed hopper 8 and then into the feed cylinder 9 through the connecting pipe 906. Driven by the motor 12, the feed shaft 901 rotates together with the main shaft 201 of the stirring mechanism 2 and the transmission mechanism 4. Under the rotation of the feed shaft 901, the spiral belt 902 cuts, pushes and disperses the cosmetic paste raw materials entering the feed cylinder 9. The cosmetic paste raw materials entering the inner tank 6 are stirred by the stirring rod 202. At the same time, the transmission mechanism 4 rotates the inner tank 6 of the mixing tank 1 in the opposite direction to the rotation of the stirring rod 202 through the meshing of the gear 13 and the gear ring 601. The dispersing protrusion 602 in the inner tank 6 cooperates with the stirring rod 202 to improve the mixing and homogenization effect.

[0040] After mixing is complete, rotate the discharge pipe 603 of the inner tank 6 to the lowest position and stop the operation of the motor 12. Then connect the discharge pipe 603 to the next processing equipment, open the solenoid valve on the discharge pipe 603, and discharge the pre-treated cosmetic paste raw material. This achieves efficient operation of the raw material pretreatment device, improves work efficiency, and effectively reduces energy consumption.
