Abstract
Description
Technical Field
[0001] This utility model relates to a mixing device, and more particularly to a mixing device for a high-temperature yellowing-resistant UV vacuum coating primer for glass bottles. Background Technology
[0002] When performing vacuum coating on glass bottles, a layer of UV vacuum coating primer is typically applied to the outer surface of the bottle. The main purpose of this primer is to cover minor defects on the glass surface, improve the fullness and gloss of the coating, and enhance the adhesion of subsequent coating layers to the glass substrate, thereby improving the overall appearance quality and reliability. For glass bottles used in high-temperature cooking or baking processes, the primer must also have good resistance to yellowing, showing no significant discoloration under high temperatures and prolonged exposure.
[0003] In actual production, it is usually necessary to add various UV prepolymers, UV monomers, initiators, and additives to a mixing tank in a certain proportion for mixing. Currently, the most common preparation method is whole-tank mixing, where all components are added to the tank at once and then mixed uniformly. This method is difficult to balance in terms of batching accuracy and mixing uniformity: on the one hand, different materials have significant differences in viscosity and density, which can easily lead to insufficient mixing in localized areas, resulting in unstable base coat performance and even coating quality defects; on the other hand, adding materials often requires the combined action of pumps and metering devices, and the addition and proportion adjustment undoubtedly increase equipment costs. Utility Model Content
[0004] This invention addresses the problems in the prior art. The technical problem to be solved by this invention is to provide a mixing device for a high-temperature resistant, yellowing-resistant UV vacuum coating base oil for glass bottles.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A mixing device for high-temperature resistant, yellowing-resistant UV vacuum coating base oil for glass bottles includes a mixing tank and a feeding device. The feeding device is connected to the mixing tank for supplying material into the mixing tank. Several feeding devices are provided, and the feeding devices include: Material tanks are used to store different materials; An injection pump, driven by a crank-connecting rod mechanism, draws various materials from a tank and pushes them into a mixing tank for stirring and mixing. A crank-connecting rod mechanism includes a rotating wheel and a connecting rod that rotates with the rotating wheel. The rotating wheel is provided with two mounting platforms. A rotatable and lockable lead screw is rotatably mounted on the mounting platforms. The lead screw is provided with a nut seat. The rotating wheel is provided with a strip hole. The nut seat extends into the strip hole and slides with the strip hole. When the lead screw is rotated, the nut seat slides along the strip hole to adjust the distance between the connection point with the connecting rod. The proportional adjustment mechanism includes a slide rail, a slider, and a drive motor mounted on the slider. The slide rail is provided with a locking bolt for locking the slider, and the output end of the drive motor is fixedly connected to a nut seat.
[0006] Preferably, the connection point between the slot and the connecting rod is located on the same straight line.
[0007] Preferably, the injection pump includes a T-shaped cylinder with a transverse section and a longitudinal section. A piston is provided in the transverse section of the T-shaped cylinder, and the outer end of the piston is rotatably connected to a connecting rod. The longitudinal section of the T-shaped cylinder has three openings at the top, right side, and left side. A cylindrical three-way shaft is provided inside the T-shaped cylinder. The two ends of the three-way shaft are rotatably sealed with the longitudinal section of the T-shaped cylinder. A sealing ring is provided between the three-way shaft and the inner wall of the longitudinal section of the T-shaped cylinder. One end of the three-way shaft extends out of the longitudinal section of the T-shaped cylinder and is provided with a turning device to turn the three-way shaft reciprocating by 90 degrees.
[0008] Preferably, the actuating device includes an actuating rod fixed to the end of the three-way shaft, and a cylinder or electric push rod rotatably connected to the actuating rod. The tail of the cylinder or electric push rod is rotatably fixed, and when the cylinder or electric push rod extends and retracts, it drives the three-way shaft to rotate 90 degrees in the forward or reverse direction.
[0009] Preferably, the three-way shaft is provided with a T-shaped channel. When extracting materials, the T-shaped channel connects the lateral section of the material tank and the T-shaped cylinder and blocks the opening on the left side of the T-shaped cylinder. When pushing out materials, the T-shaped channel connects the lateral section of the mixing tank and the T-shaped cylinder and blocks the opening on the top side of the T-shaped cylinder.
[0010] Preferably, an angle sensor is provided at the output shaft of the drive motor, and the drive motor controls the toggle device to rotate the three-way shaft when rotating half a turn and one turn.
[0011] Compared with the prior art, the present invention has the following advantages: The present application realizes the extraction and addition of materials through an injection pump, which can adapt to various fluid materials. In addition, since the piston reciprocating motion is driven by a crank-connecting rod mechanism, the amount of material added can be controlled by adjusting the stroke. The present application further adjusts the amount of material added by adjusting the piston stroke in the injection pump by adjusting the position of the rotation center, and finally realizes the change of the ratio. In addition, since the material is added in an appropriate amount and continuously, it can be better mixed evenly during stirring without stratification. This means that this addition method can also carry out continuous feeding and mixing while feeding and discharging from the bottom. Attached Figure Description

Detailed Implementation
[0014] 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.
[0015] 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
[0016] This embodiment mainly describes the title of the mixing device for high-temperature yellowing-resistant UV vacuum coating base oil used in glass bottles, as follows: like Figure 1-3 As shown, the mixing device for high-temperature anti-yellowing UV vacuum coating primer for glass bottles includes a mixing tank 20 and a feeding device. The feeding device is connected to the mixing tank 20 for feeding material into the mixing tank 20. Several feeding devices are provided, and the feeding devices include: Material tank 10 is used to store different materials; The injection pump 60 is driven by the crank-connecting rod mechanism 30 to draw various materials from the material tank 10 and push them into the mixing tank 20 for mixing. The crank-connecting rod mechanism 30 includes a rotating wheel 301 and a connecting rod 302 rotatably engaged with the rotating wheel 301. The rotating wheel 301 is provided with two mounting platforms 404. A rotatable and lockable lead screw 406 is rotatably mounted on the mounting platform 404. A nut seat 405 is provided on the lead screw 406. The rotating wheel 301 is provided with a strip hole 3011. The nut seat 405 extends into the strip hole 3011 and slides in engagement with the strip hole 3011. When the lead screw 406 is rotated, the nut seat 405 slides along the strip hole 3011 to adjust the distance between the connection point with the connecting rod 302. The proportional adjustment mechanism 40 includes a slide rail 401, a slider 402, and a drive motor 403 mounted on the slider 402. The slide rail 401 has locking bolts for locking the slider 402, and the output end of the drive motor 403 is fixedly connected to a nut seat 405. This solution uses an injection pump 60 to extract and add materials, adaptable to various fluid materials. Furthermore, because the piston reciprocates via a crank-connecting rod mechanism 30, the amount of material added is controlled by adjusting the stroke. This application further adjusts the addition amount by adjusting the piston stroke within the injection pump 60, thereby changing the proportion. Additionally, because the material is added in appropriate and continuous amounts, it can be better mixed evenly during stirring without stratification. This means that this addition method can also perform continuous feeding and discharging from the bottom simultaneously. Specifically, the discharge valve of the material tank 10 can be closed during initial stirring, and the material can be discharged while stirring after a certain amount has accumulated.
[0017] Preferably, the connection point between the strip-shaped orifice 3011 and the connecting rod 302 is located on the same straight line. Being on the same straight line eliminates the need for complex calculations, allowing for more precise control of the piston stroke. This precise adjustment of the piston stroke corresponds to the precise adjustment of the amount of material added.
[0018] Preferably, the injection pump 60 includes a T-shaped cylinder with a transverse section and a longitudinal section. A piston is provided in the transverse section of the T-shaped cylinder, and the outer end of the piston is rotatably connected to the connecting rod 302. The longitudinal section of the T-shaped cylinder has three openings at the top, right side and left side. A cylindrical three-way shaft is provided inside the T-shaped cylinder. The two ends of the three-way shaft are rotatably sealed with the longitudinal section of the T-shaped cylinder. The three-way shaft is attached to the inner wall of the longitudinal section of the T-shaped cylinder and is provided with a sealing ring. One end of the three-way shaft extends out of the longitudinal section of the T-shaped cylinder and is provided with a turning device 50 to turn the three-way shaft to reciprocate 90 degrees.
[0019] Preferably, the actuating device 50 includes an actuating rod 502 fixed to the end of the three-way shaft, and a cylinder or electric push rod 501 rotatably connected to the actuating rod 502. The tail of the cylinder or electric push rod 501 is rotatably fixed, and when the cylinder or electric push rod 501 extends and retracts, it drives the three-way shaft to rotate 90 degrees in the forward or reverse direction.
[0020] Preferably, the three-way shaft is provided with a T-shaped channel. When extracting materials, the T-shaped channel connects the material tank 10 and the transverse section of the T-shaped cylinder and blocks the opening on the left side of the T-shaped cylinder. When pushing out materials, the T-shaped channel connects the mixing tank 20 and the transverse section of the T-shaped cylinder and blocks the opening on the top side of the T-shaped cylinder.
[0021] Preferably, an angle sensor is provided at the output shaft of the drive motor 403, and the drive motor 403 controls the toggle device 50 to rotate the three-way shaft when rotating half a turn and one turn.
[0022] Additionally, it should be noted that a power supply and a lead screw motor can be installed on the rotating wheel 301, and the lead screw motor can be controlled via Bluetooth to automatically drive the lead screw 406, thereby adjusting the position of the nut seat 405 to achieve the purpose of adjusting the piston stroke.
