Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixer with improved use safety. Background Art

[0002] Disperse dyes are a special type of dyes, characterized by being dispersed in water in the form of tiny particles rather than dissolved. This dispersion allows the dye to be evenly distributed on the dyed material, thereby obtaining a uniform dyeing effect. In order to obtain an ideal dyeing effect, disperse dyes need to be fully mixed before use. At this time, the mixer comes in handy, which can not only improve the uniformity and dyeing effect of the dye, but also improve production efficiency and reduce production costs, providing strong support for the production of textiles, plastics, coatings and other industries.

[0003] In the prior art, a Chinese patent document with publication number CN218944788U proposes a mixing device for disperse dye production. The application sets a small water tank, a water pump, a shunt pipe, a built-in plate, a fixed seat and a handle. When cleaning the mixing device, the controller controls the water pump to guide the inner part of the small water tank through the shunt pipe to the nozzle, and the nozzle cleans the inner wall of the device body, the arc-shaped blades and the stirring shaft. When the surface of the built-in plate is difficult to clean, the handle is pulled to drive the built-in plate on the fixed seat to move upward, and the built-in plate is removed for deep cleaning. It has a self-cleaning function, which is easy and convenient to clean, and avoids affecting the subsequent use of the mixing device. The above patent document The invention is consistent with the prior art in that it lacks the function of automatically opening and closing the cover, and manual operation is required to open and close the cover. This may result in the cover not being closed or not being completely closed during the mixing process if the operator is negligent or operates improperly. When the mixer is in the mixing process, if the cover is not closed or not tightly closed, the material may splash out from the cover, which will not only cause waste of material, but also may cause physical harm to the operator, thereby causing safety problems. Furthermore, we disclose a mixer with improved safety of use to meet the actual needs of traditional disperse dye mixers that lack the function of automatically opening and closing the cover, resulting in certain safety hazards during use. Summary of the invention

[0022] like Figures 1 to 4As shown, a mixer with improved safety in use comprises a body 1 and a cover 2 rotatably connected to both sides of the upper end of the body 1, a servo motor 16 is arranged in the middle of the upper end surface of the body 1, the output end of the servo motor 16 extends into the interior of the body 1 and is fixedly connected to a stirring rod 15, a stop rod 5 is fixedly connected to the upper end of an outer wall of one side of the stirring rod 15, automatic switch components for controlling the switch of the cover 2 are arranged on both sides of the upper end of the inner wall of the body 1, the automatic switch components comprise a guide frame 8 fixedly connected to the body 1, a slide groove 6 is provided inside the guide frame 8, a fixed block 10 is slidably connected inside the slide groove 6, when the mixer is stirring, the cover 2 is closed by the automatic switch component, when the mixer stops stirring, the cover 2 is automatically opened, through this structural design, the safety and convenience of use of the mixer are greatly improved.

[0023] Further, such as Figures 1 to 4 As shown, a telescopic spring 7 is fixedly connected to one end face of the fixed block 10, and one end of the telescopic spring 7 away from the fixed block 10 is fixedly connected to one inner wall of the slide groove 6, a pull rope 9 is fixedly connected to the middle of the upper end face of the fixed block 10, and the upper end of the pull rope 9 is fixedly connected to the cover 2, and a connecting rod 11 is fixedly connected to the middle of the end face of the fixed block 10 away from the telescopic spring 7, and the inclination directions of the connecting rods 11 on both sides are opposite, and multiple buffer springs 14 are fixedly connected to both sides of the inner walls of the upper and lower ends of the slide groove 6. 14 is fixedly connected to a limit block 13 at one end, a slider 12 is slidably connected between the limit blocks 13 at both ends of the adjacent ends, and the slider 12 is fixedly connected to the fixed block 10. Both sides of the middle of the upper end surface of the body 1 are fixedly connected to a vertical plate 3, and a tension spring 4 is fixedly connected to the middle of one end surface of the vertical plate 3. The end of the tension spring 4 away from the vertical plate 3 is fixedly connected to the cover 2. When the stirring rod 15 inside the mixer is driven by the servo motor 16 to rotate, the push rod 5 also rotates, and when the push rod 5 rotates, it is connected with the automatic opening When the lever 11 is in contact with the connecting rod 11, the lever 11 is in contact with the connecting rod 11, and the lever 11 is in contact with the connecting rod 11, so that the fixing block 10 slides backward through the action of the connecting rod 11, and the fixing block 10 slides backward to drive the lower end of the pull rope 9 to move to one side, thereby causing the upper end of the pull rope 9 to give the cover 2 a downward force, driving the cover 2 to complete the closing. In addition, the fixing block 10 is connected to the slide groove 6 through the slider 12, and a speed control structure is arranged at both ends of the slider 12. Through the restriction of the buffer spring 14 and the limit block 13, after the lever 5 cancels the contact with the connecting rod 11, the rebound speed of the fixing block 10 can be slowed down by the telescopic spring 7, and the rotation speed of the lever 5 is faster. Therefore, the lever 5 keeps rotating continuously, which can ensure that the position of the fixing block 10 is difficult to slide, thereby improving the closing stability of the cover 2. When the stirring rod 15 stops rotating, the fixing block 10 is reset by the telescopic spring 7, and the tensioning spring 4 opens the cover 2 through the tensioning force, thereby realizing the operation of automatically opening and closing the cover 2 according to the rotation of the stirring rod 15.

[0024] Working principle: When the stirring rod 15 inside the mixer is driven to rotate by the servo motor 16, the push rod 5 also rotates. When the push rod 5 rotates, it contacts the connecting rod 11 on the automatic switch assembly and continues to rotate. The push rod 5 contacts the connecting rod 11, so that the fixed block 10 slides backward through the action of the connecting rod 11. The fixed block 10 slides backward and drives the lower end of the pull rope 9 to move to one side, so that the upper end of the pull rope 9 gives the cover 2 a downward force, driving the cover 2 to complete the closing. In addition, the fixed block 10 is slidably connected to the slide groove 6 through the slider 12. Speed ​​control structures are provided at both ends of the slider 12. The slider 12 is slidably connected between the two groups of limit blocks 13 through the restriction of the buffer spring 14 and the limit block 13. Rounded corners are provided at both ends of the limit block 13. The slider 12 slides and contacts with the limit block 13. The rounded corners are set so that the slider 12 squeezes the limit block 13 to both ends. The buffer spring 14 is used to slow down the movement of the limit block 13 to both sides. Therefore, the passing speed of the slider 12 is also greatly reduced. Multiple groups of buffer springs 14 and the limit block 13 are set to greatly reduce the rebound speed of the slider 12. The rotation speed of the push rod 5 is relatively fast, so the push rod 5 keeps rotating, which can ensure that the position of the fixed block 10 is difficult to slide, thereby improving the closing stability of the device cover 2. When the stirring rod 15 stops rotating, the fixed block 10 is reset by the telescopic spring 7, and the tension spring 4 opens the device cover 2 by the tensioning force, thereby realizing the operation of automatically opening and closing the device cover 2 according to the rotation of the stirring rod 15.
