[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0024] Please see the appendix Figure 1-4A protective film adhesive uniform mixing device includes a support plate 1, a support frame 2, a positioning device, a mixing cylinder 3, a moving device, and a sealing cap 11 device. The support plate 1 is disposed on the top of the support frame 2, the positioning device is disposed on the support frame 2, the mixing cylinder 3 is located inside the positioning device, the moving device is disposed at the bottom of the mixing cylinder 3, the sealing cap 11 device is disposed on the support plate 1, and the mixing device is disposed on the sealing cap 11 device.
[0025] The stirring device includes a motor 4, a rotating shaft 5, a first stirring rod 6, steel spikes 7, and a second stirring rod 8. The motor 4 is mounted on the sealing cover 11 device, the rotating shaft 5 is mounted on the output end of the motor 4, the first stirring rod 6 is symmetrically arranged on both sides of the rotating shaft 5, the steel spikes 7 are evenly spaced on the first stirring rod 6, and the second stirring rod 8 is mounted on the bottom end of the rotating shaft 5. When the second stirring rod 8 is working, it is in contact with the bottom of the stirring drum 3.
[0026] Using the above technical solutions, the positioning device is used to precisely fix the position of the mixing drum 3, ensuring stability during the mixing process. The moving device allows the mixing drum 3 to be adjusted in position or moved to other working areas when needed. The sealing device 11 is used to seal the mixing drum 3 to prevent glue from splashing during the mixing process. The mixing device is responsible for the uniform mixing of the glue; the motor 4 serves as the power source, driving the first mixing rod 6 and the second mixing rod 8 to rotate via the rotating shaft 5. The first mixing rod 6 is symmetrically arranged on both sides of the rotating shaft 5, and the steel spikes 7 on it can penetrate deep into the glue, effectively breaking up agglomerates in the glue and improving mixing efficiency. The uniform spacing of the steel spikes 7 ensures that the glue is evenly stressed in all directions. At the same time, during the glue mixing process, the steel spikes 7 can prevent the glue from rolling and generating air bubbles, thereby achieving the technical effect of uniform mixing. The second mixing rod 8 is located at the bottom of the rotating shaft 5 and fits against the bottom of the mixing drum 3 during operation, ensuring that the glue at the bottom is also fully mixed, avoiding sedimentation and clumping.
[0027] In some embodiments, the sealing device includes a cylinder 9, a protective cover 10, and a sealing cover 11. The cylinder 9 is mounted on the support plate 1, the protective cover 10 is mounted on the output end of the cylinder 9, the sealing cover 11 is mounted on the bottom of the protective cover 10, and the top of the protective cover 10 and the sealing cover 11 are hollowly arranged. The motor 4 is mounted on the top of the sealing cover 11 and is located between the protective cover 10 and the sealing cover 11. The sealing cover 11 is in contact with the stirring cylinder 3.
[0028] Using the above technical solution, cylinder 9 serves as the power source, and through the extension and retraction of its output end, it drives the protective cover 10 and the cover 11 to move up and down. When it is necessary to seal the mixing drum 3, cylinder 9 extends, and the protective cover 10 and the cover 11 descend. The cover 11 contacts and cooperates with the mixing drum 3 to form a seal. The hollow setting between the top of the protective cover 10 and the cover 11 not only reduces the overall weight, but also provides installation space for the motor 4. The motor 4 is located between the protective cover 10 and the cover 11, and drives the mixing device to rotate through the rotating shaft 5.
[0029] In some embodiments, the positioning device includes a fixed frame 12, a fixed half-ring 13, and a movable half-ring 14. The fixed frame 12 is mounted on the support frame 2, and the fixed half-ring 13 is mounted on the top of the fixed frame 12. One side of the movable half-ring 14 is rotatably connected to the fixed half-ring 13, and the other ends of the movable half-ring 14 and the fixed half-ring 13 are magnetically connected. When the fixed half-ring 13 and the movable half-ring 14 are closed, they form a closed ring shape. The outer wall of the stirring cylinder 3 is in contact with the inner wall of the closed movable half-ring 14 and the fixed half-ring 13. One end of the movable half-ring 14 and the fixed half-ring 13 is provided with a magnet, and the other ends of the movable half-ring 14 and the fixed half-ring 13 are magnetically connected.
[0030] Using the above technical solution, the fixed frame 12 is stably installed on the support frame 2, providing support for the fixed half ring 13 and the movable half ring 14. The fixed half ring is fixed on the fixed frame 12, and the movable half ring 14 can be easily opened or closed by rotating it with the fixed half ring 13 on one side. The other ends of the movable half ring 14 and the fixed half ring 13 are magnetically connected. When the two are closed, they form a complete circular structure that fits tightly against the outer wall of the mixing drum 3, ensuring the stability and positional accuracy of the mixing drum 3 during the mixing process.
[0031] The magnetic connection between the movable half-ring 14 and the fixed half-ring 13 is achieved by setting magnets at one end of both. When the movable half-ring 14 approaches the fixed half-ring 13, the attraction of the magnets causes the two to automatically align and fit tightly together. Through magnetic pre-connection, the mixing drum 3 is positioned, making it easier for the subsequent mixing device to extend into the mixing drum 3 to mix the glue. It should be noted that the mixing drum 3 itself can be fixed by other locking devices, thereby preventing the mixing drum 3 from shaking excessively during the mixing process.
[0032] In some embodiments, the moving device includes casters 15, which are disposed at the bottom of the mixing drum 3. Specifically, the casters 15 can be omnidirectional or directional casters, allowing the mixing drum 3 to move and adjust flexibly on a horizontal plane. When it is necessary to move the mixing drum 3, it can be done simply by pushing or pulling it, which is convenient and quick.
[0033] In some embodiments, the first stirring rod 6 includes a vertical rod 61 and a large U-shaped rod 62. The vertical rod 61 is disposed on the upper side of the rotating shaft 5, and the number of large U-shaped rods 62 is three, which are evenly spaced on the vertical rod 61.
[0034] Vertical rod 61 is positioned on the upper side of rotating shaft 5 to support and connect large U-shaped rods 62. Three large U-shaped rods 62 are evenly spaced on vertical rod 61, allowing the stirring rod to more comprehensively cover the glue inside the mixing drum 3 during rotation, improving the uniformity and efficiency of mixing. The shape of the large U-shaped rods 62 also helps break up agglomerates in the glue, promoting uniform mixing. Simultaneously, the placement of the large U-shaped rods 62 provides more contact area for the steel spikes 7, thereby increasing the number of steel spikes 7, improving the puncture rate of air bubbles during glue mixing, and enhancing the uniform mixing effect.
[0035] Working principle:
[0036] First, pour the protective film adhesive into the mixing drum 3, ensuring that the amount of adhesive does not exceed the capacity limit of the mixing drum 3. Place the mixing drum 3 in the positioning device. The fixed half ring 13 of the positioning device has been firmly installed on the top of the support frame 2. The movable half ring 14 can be easily opened by rotating the connection on one side. Align the mixing drum 3 with the fixed half ring 13, and then close the movable half ring 14. The other ends of the movable half ring 14 and the fixed half ring 13 are tightly attached by magnetic connection to form a complete ring structure that tightly wraps the outer wall of the mixing drum 3.
[0037] Next, the sealing cap 11 device is activated. The cylinder 9, acting as the power source, begins to work, with its output end extending to drive the protective cover 10 and the sealing cap 11 downwards. The sealing cap 11 gradually approaches the opening of the mixing drum 3 and finally contacts and engages with the mixing drum 3 to form a seal. The hollow arrangement between the top of the protective cover 10 and the sealing cap 11 ensures the installation space for the motor 4 while reducing the overall weight.
[0038] After the sealing device 11 completes the sealing, the stirring device is ready to start working. The motor 4 is started, and the shaft 5 on its output end begins to rotate. The first stirring rod 6 and the second stirring rod 8 on the upper side of the shaft 5 also rotate accordingly. The steel spikes 7 on the first stirring rod 6 penetrate into the glue evenly and at intervals, ready to stir. The second stirring rod 8 is located at the bottom end of the shaft 5 and keeps in contact with the bottom of the stirring drum 3 to ensure that the glue at the bottom is also fully stirred;
[0039] Motor 4 continuously drives shaft 5 to rotate, and the first stirring rod 6 and the second stirring rod 8 stir the adhesive at a certain speed and direction. The steel spikes 7, acting on the first stirring rod 6, effectively break up agglomerates in the adhesive, improving stirring efficiency. Simultaneously, the second stirring rod 8 adheres to the bottom of the mixing drum 3, preventing adhesive sedimentation and clumping. The entire stirring process continues until the adhesive reaches the desired homogeneous state.
[0040] When the mixing reaches the predetermined time or the glue reaches the required uniformity, the motor 4 stops working. At this time, the cylinder 9 of the sealing device 11 begins to retract, and the protective cover 10 and the sealing cover 11 gradually rise, releasing the seal on the mixing drum 3. The movable half-ring 14 and the fixed half-ring 13 are separated by magnetic connection, and the mixing drum 3 can be easily removed.
[0041] This application separates the stirring device from the stirring drum 3 and works in conjunction with the moving device and the positioning device. Simply move the stirring drum 3 containing the glue to be stirred into the positioning device, and then stir it through the stirring device. After stirring is completed, replace the stirring drum 3 with a new one, so that the stirring device can continuously stir and improve stirring efficiency.
[0042] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
