Description
Technical Field
[0001] The utility model relates to the technical field of mixing equipment, in particular to a color mixing machine for a seam beautifying agent. Background Art
[0002] Sealing agent is a semi-fluid building material formed by mixing polymers and pigments. It is mainly used to fill the gaps between tiles and marble tiles on the floor and walls of houses. It plays a decorative role and can also prevent dust and dirt from entering the gaps and causing the gaps to turn black. The seaming agents produced by factories usually only have basic colors such as red, blue, yellow, green, black, and white. When decorating a house, in order to make the seaming agent match the color of tiles and marble tiles or produce the desired decoration effect, it is necessary to mix and adjust the color of the basic color seaming agent to obtain seaming agents of other colors.
[0003] The coloring of caulking agent is the process of mixing two or more basic colors of caulking agent glue evenly. A color mixing machine is used for caulking agent coloring. Several different basic colors of caulking agents are poured into the color mixing cylinder, and the caulking agents are mixed evenly by mechanical stirring. The amount of caulking agent used in actual decoration varies greatly. Sometimes only two or three bottles of caulking agent are needed, and sometimes more than ten bottles of caulking agent are needed. There must be a certain thickness of glue at the bottom of the color mixing cylinder for stirring. If a large color mixing cylinder is used to mix a small amount of glue, there is only a thin layer of glue at the bottom of the color mixing cylinder, and the caulking agent is difficult to mix evenly. Therefore, multiple sets of color mixing machines or color mixing cylinders suitable for different amounts of glue are required. If multiple sets of color mixing machines are configured, the cost is high and it takes up a large space. If multiple color mixing cylinders are configured, it is troublesome to replace and fix the color mixing cylinders. Utility Model Content

[0028] Working process: When the caulking agent is being mixed and adjusted, the lifting motor 10 is started, the chain 9 pulls up the tray 8, and the tray 8 slides upward along the guide rail 43, and the stirring device rises accordingly, the pressure cover 6 is separated from the fixed cylinder 2, the lifting motor 10 is turned off, the second sprocket 101 stops rotating, and the chain 9 and the tray 8 stop moving and the position is locked. According to the total amount of the caulking agent glue, a replaceable color mixing cylinder 13 of suitable volume is selected, and the clamping ring formed by the elastic gripper 31 and the tensioning spring 32 is stretched open, and the replaceable color mixing cylinder 13 is placed in the clamping ring, and then the clamping ring is released. The elastic gripper 31 tightly squeezes the outer wall of the replaceable color mixing cylinder 13, and the tensioning spring 34 pushes the push rod 33 toward the center of the fixed cylinder 2, increasing the squeezing force of the elastic gripper 31 on the replaceable color mixing cylinder 13, and the replaceable color mixing cylinder 13 is clamped and fixed; the bottom of the replaceable color mixing cylinder 13 and the tensioning spring 32 are pressed together. There is friction between the anti-skid pads 21. Under the joint action of the elastic holding structure 3 and the anti-skid pads 21, when the stirring rod 5 mixes and stirs the caulking agent glue, the replaceable color mixing cylinder 13 will not fall over, move or rotate. After the replaceable color mixing cylinder 13 is placed and fixed, the caulking agent glue of different colors is poured into the replaceable color mixing cylinder 13, the lifting motor 10 rotates in the opposite direction, the tray 8 slides downward along the guide rail 43, and the stirring device and the pressure cover 6 are lowered until the pressure cover 6 is tightly pressed against the fixed cylinder 2. At this time, the fixed cylinder 2 The open end of the cylinder 2 is sealed, and one side of the tray 8 is supported on the lower fixed block 41 to improve the stability of the color mixing machine during operation; after the fixed cylinder 2 is sealed, the control valve 62 is opened, the connecting valve 64 is closed, and the vacuuming device is turned on to vacuumize the internal cavity of the fixed cylinder 2. When the negative pressure gauge 63 detects that the internal cavity of the fixed cylinder 2 reaches a certain negative pressure value, the vacuuming is stopped, the control valve 62 is closed, and then the color mixing of the caulking agent is started, the stirring motor 7 is started, and the stirring rod 5 rotates to stir and mix the caulking agent glue in the replaceable color mixing cylinder 13. The mixing of the caulking agent glue is carried out under vacuum conditions to prevent the generation of bubbles. When the coloring is completed, the stirring motor 7 is stopped, and the connecting valve 64 is slowly opened to allow external air to enter the fixed cylinder 2, which is conducive to lifting the gland 6. The lifting motor 10 is started, and the chain 9 pulls the support tray 8 upward along the guide rail 43. The stirring device and the gland 6 rise accordingly, and the clamping ring formed by the elastic gripper 31 and the tensioning spring 32 is opened.
