Description

Technical Field

[0001] This utility model relates to a mixer, and more particularly to a mixing device for manufacturing a heat-resistant, thin-coat UV vacuum coating primer for ABS+PC substrates. Background Technology

[0002] This UV vacuum coating primer, used to manufacture heat-resistant, thin-coat ABS+PC substrates, is a UV-curable coating specifically designed for vacuum coating processes. This primer must exhibit excellent adhesion to the ABS+PC plastic surface, high-temperature heat resistance, and provide a smooth and dense base layer for subsequent vacuum coating processes (such as aluminum plating).

[0003] To achieve the aforementioned performance, the primer formulation typically contains a large amount of high molecular weight resin. These resins have high viscosity and are difficult to disperse. If the mixing is insufficient, they are prone to agglomeration or sedimentation, severely affecting the uniformity of the coating and its final performance. Therefore, extremely high requirements are placed on the uniformity of mixing during the production process.

[0004] However, most common mixing equipment on the market currently uses unidirectional stirring, creating only a single vortex and tangential flow within the liquid. This stirring method has significant limitations: continuous unidirectional rotation creates deep vortices in the center of the liquid, increasing the risk of air entrainment and leading to defects such as bubbles and pinholes after coating; simultaneously, the material mainly undergoes circular motion, with weak radial and axial mixing. Higher-density pigments or fillers tend to deposit towards the container walls and bottom under centrifugal force, resulting in lower concentrations in the central region and creating significant mixing dead zones. These problems are even more pronounced in systems containing high-molecular-weight resins, easily leading to uneven resin dispersion, decreased system stability, and ultimately affecting product consistency and finished product quality. Utility Model Content

[0005] This invention addresses the problem of uneven mixing caused by unidirectional stirring in the prior art. The technical problem to be solved by this invention is to provide a stirring device for manufacturing a UV vacuum coating base oil for resistant, thin-coat ABS+PC substrates.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A stirring device for manufacturing a heat-resistant, thin-coat UV vacuum coating primer for ABS+PC substrates includes a tank, a stirring assembly disposed within the tank, and a drive assembly disposed at the top of the tank. The drive assembly includes: First motor; The planetary gear set has one end of its sun gear connected to the output shaft of the first motor, and the other end of its sun gear connected to the stirring assembly; The second motor is connected to the external gear ring of the planetary gear set via a transmission. The ratchet locking mechanism includes a ratchet mounted on the planetary carrier of the planetary gear set and a pawl for unidirectionally locking the ratchet and thus unidirectionally locking the planetary carrier; a first motor and a second motor are used to drive the sun gear and its stirring assembly to rotate in opposite directions to stir the raw materials in the tank.

[0007] Preferably, the planetary gear set includes a sun gear, planet gears, an external gear ring, and a planet carrier. The planet gears mesh with both the sun gear and the external gear ring, and the planet gears are rotatably mounted on the planet carrier.

[0008] Preferably, the top of the tank is provided with a mounting base, the first motor is mounted on the mounting base and the first motor is provided with a shaft cover, the second motor is fixed on the shaft cover, and the second motor meshes with the outer teeth of the outer gear ring through gears.

[0009] Preferably, the planetary carrier has a cylinder at the top, the middle of which is used for the motor shaft of the first motor to pass through, and a ratchet groove on the side wall of the cylinder. The pawl is rotatably mounted on the shaft cover, and an electric push rod is rotatably mounted on the shaft cover. The output end of the electric push rod is rotatably connected to the pawl to drive the pawl to engage and disengage with the ratchet groove.

[0011] Preferably, the first motor, the second motor, and the electric actuator are controlled by the same controller.

[0012] Compared with the prior art, the present invention has the following advantages: First, the present application realizes the forward and reverse rotation of the stirring component to ensure uniform stirring; second, by setting a planetary gear set to cooperate with two motors to drive the forward and reverse rotation of the stirring component, it is easier to control than directly driving it forward and reverse with a single motor and can avoid the impact on the motor when switching directions.

Detailed Implementation

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0016] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0017] This embodiment mainly describes the title of the stirring device used to manufacture a heat-resistant, thin-coat UV vacuum coating primer for ABS+PC substrates, as follows: like Figure 1-5 As shown, a stirring device for manufacturing a heat-resistant, thin-coat UV vacuum coating primer for ABS+PC substrates includes a tank 10, a stirring assembly 40 disposed within the tank 10, and a drive assembly 20 disposed on the top of the tank 10. The drive assembly 20 includes: First motor 201; The planetary gear set 203 has one end of its sun gear 2034 connected to the output shaft of the first motor 201, and the other end of its sun gear 2034 connected to the stirring assembly 40. The second motor 202 is connected to the outer gear ring 2032 of the planetary gear set 203. The ratchet locking mechanism includes a ratchet 20311 mounted on the planetary carrier 2031 of the planetary gear set 203 and a pawl 20312 for unidirectionally locking the ratchet 20311 and thus unidirectionally locking the planetary carrier 2031. A first motor 201 and a second motor 202 drive the sun gear 2034 and its agitator 40 to rotate in opposite directions to agitate the raw materials in the tank 10. This design firstly achieves forward and reverse rotation of the agitator 40, ensuring uniform mixing; secondly, by using the planetary gear set 203 in conjunction with two motors to drive the agitator 40 in both directions, it is easier to control than directly using a single motor for forward and reverse rotation, and it avoids the impact on the motor during direction switching. The specific method is as follows: the first motor 201 drives the sun gear 2034 and the stirring assembly 40 to rotate in opposite directions, and the ratchet locking mechanism is in a disengaged state. About 1 second before it stops, the second motor 202 is started to rotate in opposite directions and its speed is increased in about 1 second until the angles of the outer gear ring 2032 and the sun gear 2034 are consistent. After the increase is completed, when the first motor 201 stops, the planetary carrier 2031 is locked by the ratchet locking mechanism. At this time, the outer gear ring 2032 drives the sun gear 2034 to rotate in the forward direction through the planetary gears 2033 to achieve the direction switch. If multiple alternating rotations are required, one alternating process is set as one cycle. A short stop is made when switching between adjacent cycles. Since the forward rotation is driven by the outer gear ring 2032, the angular velocity of the sun gear 2034 is a decreasing process. Therefore, a short stop between adjacent cycles can avoid damaging the first motor 201.

[0018] Preferably, the planetary gear set 203 includes a sun gear 2034, planet gears 2033, an external gear ring 2032, and a planet carrier 2031. The planet gears 2033 mesh with both the sun gear 2034 and the external gear ring 2032, and the planet gears 2033 are rotatably mounted on the planet carrier 2031.

[0019] Preferably, the top of the tank body 10 is provided with a mounting base 30, the first motor 201 is mounted on the mounting base 30 and the first motor 201 is provided with a shaft cover 200, the second motor 202 is fixed on the shaft cover 200, and the second motor 202 meshes with the outer teeth of the outer gear ring 2032 through gears.

[0020] Preferably, the planetary carrier 2031 has a cylinder at its top, with the motor shaft of the first motor 201 passing through the middle of the cylinder. The side wall of the cylinder has a ratchet groove. A pawl 20312 is rotatably mounted on the shaft cover 200, and an electric push rod 204 is rotatably mounted on the shaft cover 200. The output end of the electric push rod 204 is rotatably connected to the pawl 20312, driving the pawl 20312 to engage and disengage from the ratchet groove. This design controls the locking of the planetary carrier 2031 by rotating the pawl using the electric push rod 204, resulting in more precise control. The shaft cover 200 has a mounting plate on which both the pawl 20312 and the electric push rod 204 are mounted.

[0021] Preferably, the first motor 201 is used to drive the stirring assembly 40 to rotate in reverse, and the second motor 202 is used to drive the stirring assembly 40 to rotate in the forward direction. Since the product inside has inertia after forward rotation, it is more effective to use a higher-power motor for reverse rotation.

[0022] Preferably, the first motor 201, the second motor 202, and the electric push rod 204 are controlled by the same controller. The controller can be a time relay, a PLC, or a microcontroller.

[0023] It should also be noted that the stirring assembly 40 includes a stirring shaft and stirring blades mounted on the stirring shaft; in practice, the two motors use the same specifications.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
