Description

Technical Field

[0001] This utility model relates to the technical field of iron pipe production and processing, specifically to a coating mixing device for printing iron cans. Background Technology

[0002] In the traditional tin can packaging industry, the mixing process of coatings for printed tin cans has long faced multiple technical bottlenecks. Early mixing devices mostly adopted a single-shaft stirring structure, which resulted in uneven shear force distribution leading to pigment agglomeration and insufficient resin dispersion, affecting the uniformity and adhesion of the coating. Solvent-based coatings generally face challenges in volatilization control during mixing; open stirring tank designs lead to excessive VOC emissions, and the poor precision of manual feeding easily causes fluctuations in the mixing ratio. For high-viscosity metallic coatings, conventional propeller impellers easily create mixing dead zones, requiring extended stirring time to compensate, resulting in low energy efficiency (typically only 30-40%). Temperature-sensitive coatings lack precise temperature control modules during mixing, and localized overheating can easily trigger pre-crosslinking reactions. Patent searches show that although CN201520382U improved the stirring blade angle, it did not solve the problem of axial / radial flow field coordination; JP 2018-154722 adopted a double-layer stirring design, but this resulted in a 27% increase in energy consumption. Current technologies have not effectively integrated multi-functional units such as dispersion, grinding, and viscosity adjustment, resulting in production lines requiring multiple independent devices, large floor space, and batch-to-batch quality variations. These technical deficiencies directly restrict the impact resistance (typically <50 kg·cm) and corrosion resistance (salt spray test <500h) of metal packaging coatings, particularly in the field of food-grade coatings.

[0003] Application number CN201921304155.9 discloses a coating mixing device for printed tin cans, which solves the shortcomings of uneven mixing in existing coating mixing devices. The device includes a mixing chamber, a receiving hopper, an input quantity adjustment device, and a gearbox. A receiving pipe is located at the upper end of one side of the mixing chamber, and a liquid inlet pipe is located at the upper end of the other side. The receiving hopper is located at the upper end of the receiving pipe. The input quantity adjustment device is located on the receiving pipe and at the lower end of the receiving hopper. The input quantity adjustment device includes a rotating disk, a rotating shaft, and a housing. The rotating shaft is located at the center of the rotating disk, and both ends of the rotating shaft are fixedly supported by rolling bearings installed in the housing. The gearbox is located at the top of the mixing chamber, and a drive shaft is located in the mixing chamber. By adjusting the input quantity adjustment device, the input amount of solid coating raw materials can be controlled, making the solid and liquid raw materials more evenly and thoroughly mixed during mixing. However, a drawback is that the device operates in a horizontal mixing direction, resulting in a certain lag in mixing efficiency, which leads to low production capacity. Utility Model Content

[0025] Please see Figures 1-4 As shown, this utility model is a coating mixing device for printed tin cans, including a supporting guide assembly 1, which is fixedly installed on the top of the convenient push plate assembly 2, and a transmission assembly 3 is fixedly installed on one side of the top of the supporting guide assembly 1. A rotating bracket assembly 4 is installed at the transmission end of the transmission assembly 3, and a mixing tank assembly 5 is installed at the middle of the rotating bracket assembly 4.

[0026] The transmission assembly 3 includes a rotary motor 301, which is fixedly mounted on the top side of the support base 101 via a bracket. A transmission box 302 is mounted on the outside of the rotary motor 301, and a transmission device 303 is fixedly mounted on the other side of the transmission box 302. The transmission end of the transmission device 303 is connected to an active clamping wheel 304. A connecting rod 305 is fixedly mounted between the two active clamping wheels 304. The connecting rod 305 passes through one side of the rotating groove 102, and a matching clamping wheel is limited and mounted on the other side of the rotating groove 102. The rotary motor 301 in the transmission assembly 3 serves as a power source, and its output power is transmitted to the active clamping wheel 304 via the transmission box 302 and the transmission device 303. The active clamping wheel 304 cooperates with the matching clamping wheel to drive the rotating support assembly 4 to rotate.

[0027] By installing a transmission component 3 on the device, when using this device, the transmission component 3 is connected to the bottom side of the mixing tank component 5. This allows the transmission component to achieve a rotation effect during the mixing process of the mixing tank component 5, thereby accelerating the mixing process.

[0028] The material guide assembly 1 includes a support base 101, a rotating groove 102 is provided at the top center of the support base 101, and a reinforcing support rod 103 is fixedly installed at the bottom of the support base 101. A guide rail 104 is provided on the outer side of the rotating groove 102.

[0029] The convenient push plate assembly 2 includes a movable push plate 201. Limiting slide rails 202 are fixedly installed on both sides of the top of the movable push plate 201. A movable slider 203 is slidably installed in the middle of the limiting slide rails 202. A fixed support plate 204 is fixedly installed on the top of the movable slider 203. The bottom of the support base 101 is fixedly installed on the top of the fixed support plate 204. Mounting plates 205 are fixedly installed on both ends of one side of the fixed support plate 204. Pressing knobs 206 are fixedly installed on the outer sides of the mounting plates 205 on both sides. The ends of the pressing knobs 206 abut against the outer walls of the movable push plate 201.

[0030] The movable push plate 201 includes a fixed bracket 2011. The fixed bracket 2011 has a mounting clip 2012 fixedly installed diagonally at the bottom. The mounting clip 2012 has a movable roller 2013 installed in the middle limit position. The convenient push plate assembly 2 realizes the overall movement of the device through the movable roller 2013, and uses the extrusion knob 206 to fix the position of the support guide assembly 1 to ensure the stability of the mixing process.

[0031] The rotating support assembly 4 includes a limiting ring 401, which is slidably installed on the inner side of the driving clamping wheel 304 and the matching clamping wheel. Fixed steel frames 402 are fixedly installed on both sides of the limiting ring 401. The two fixed steel frames 402 form a square in the middle of the limiting ring 401, and a fixed side plate 403 is fixedly installed in the middle of the two fixed steel frames 402.

[0032] The mixing tank assembly 5 includes an electrically controlled rotor 501, which is fixedly mounted on the outside of a fixed side plate 403 on one side via a bracket. A stirring device 502 is fixedly mounted at the end of the electrically controlled rotor 501. The stirring device 502 is limited and installed inside the mixing tank 503, which is limited and fixed between two fixed side plates 403. A discharge port 504 is opened at the top of the mixing tank 503. The mixing tank assembly 5 on the rotating bracket assembly 4 rotates accordingly. At the same time, the electrically controlled rotor 501 inside the mixing tank assembly 5 drives the stirring device 502 to stir the coating, realizing the movement of the coating in different directions, thereby achieving the purpose of uniform mixing.

[0033] This coating mixing device for printed tin cans primarily achieves coating mixing based on mechanical transmission and stirring principles. The rotary motor 301 in the transmission assembly 3 serves as the power source, transmitting its output power through the transmission box 302 and transmission device 303 to the drive clamping wheel 304. The drive clamping wheel 304, in conjunction with the matching clamping wheel, drives the rotating support assembly 4 to rotate. The mixing tank assembly 5 on the rotating support assembly 4 rotates accordingly, while the electrically controlled rotating mechanism 501 within the mixing tank assembly 5 drives the stirring device 502 to stir the coating, achieving uniform mixing by moving the coating in different directions. The convenient pusher assembly 2 moves the entire device via the moving rollers 2013 and uses the pressing knob 206 to fix the position of the support guide assembly 1, ensuring a stable mixing process. The guide rail 104 of the support guide assembly 1 provides an outlet path for the mixed coating. During operation, the support guide assembly 1 is installed on the movable slider 203 of the convenient push plate assembly 2 via the fixed support plate 204. The relative position of the fixed support plate 204 and the movable push plate 201 is adjusted by the squeeze knob 206 to ensure that the support guide assembly 1 is stable. Install the transmission assembly 3 so that the connecting rod 305 passes through the rotating groove 102, and install the active clamping wheel 304 and the driven clamping wheel in place; place the limiting ring 401 of the rotating support assembly 4 inside the active clamping wheel 304 and the driven clamping wheel, fix the steel frame 402 and the fixed side plate 403 to install and fix the mixing tank assembly 5, and ensure that the mixing tank 503 is in an accurate position. Add the paint to be mixed into the mixing tank 503 through the discharge port 504 at the top of the mixing tank 503, turn on the rotary motor 301, and its power drives the rotating support assembly 4 to rotate around the rotating groove 102 through the transmission assembly 3; at the same time, start the electric control motor 501 to drive the stirring device 502 to stir the paint in the mixing tank 503. During this process, the rotation of the rotating support assembly 4 causes the mixing tank 503 to rotate in a circular motion, while the stirring device 502 stirs and shears the coating inside the tank. The two motions work together to achieve thorough mixing of the coating. If the device position needs to be adjusted during the mixing process, the squeezing knob 206 can be loosened, and the device can be moved to a suitable position by moving the roller 2013 at the bottom of the moving push plate 201. Then, the squeezing knob 206 can be tightened to fix it. After the coating is evenly mixed, the rotating motor 301 and the electrically controlled rotating machine 501 are turned off. The mixed coating is discharged through the discharge port 504 at the top of the mixing tank 503 and transported to the subsequent processing stage along the discharge track 104 of the supporting guide assembly 1. After the coating mixing is completed, the mixing tank 503, stirring device 502 and other components are cleaned, and the connection parts of each component are checked for looseness. Worn parts are replaced in time to prepare for the next use.
