Since the ratio of various raw materials will be determined before the reaction, when the mixing equipment is used again, the dirt on its inner wall will affect the ratio of the raw materials and reduce the quality of the formed hot melt adhesive.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 As shown, the utility model provides a high-efficiency mixing device for hot melt adhesive production, including a mixing barrel 1, a feeding port is provided at the top of the mixing barrel 1, a plurality of support frames are fixedly connected to the barrel body of the mixing barrel 1, a discharging port is provided at the bottom of the mixing barrel 1, a motor 2 is installed at the center of the top of the mixing barrel 1, the output shaft of the motor 2 rotates and penetrates into the mixing barrel 1, and a stirring mechanism is provided below the output shaft of the motor 2;

[0022] The stirring mechanism includes a rotating rod 6 vertically arranged below the output shaft of the motor 2, a plurality of stirring rods are fixedly connected to the body of the rotating rod 6, a fixed sleeve 18 is rotatably sleeved at the bottom of the body of the rotating rod 6, a fixed strip 19 is fixed between the fixed sleeve 18 and the inner wall of the mixing barrel 1, and a transmission component is arranged between the rotating rod 6 and the output shaft of the motor 2;

[0023] The transmission component includes two bevel gears 3, which are respectively fastened and sleeved on the output shaft of the motor 2 and the top of the shaft of the rotating rod 6. A supporting drum 5 is also vertically rotatably arranged on the inner wall of the mixing barrel 1, and a sub-gear 4 is fastened and sleeved on the shaft of the supporting drum 5. The sub-gear 4 is meshed with the two bevel gears 3.

[0024] Through the arrangement of the mixing barrel 1, the motor 2 and the stirring mechanism, the discharge port is firstly sealed with a piston so that the material will not accidentally leak out before the mixing is completed, and then the proportioned raw materials are poured into the inner cavity of the mixing barrel 1 from the feed port, and then the motor 2 is started, and the output shaft of the motor 2 drives the bevel gear 3 to start rotating, and then the bevel gear 3 drives the sub-gear 4 to start rotating, and the sub-gear 4 drives the rotating rod 6 and the stirring rod to start rotating through the bevel gear 3 fixedly sleeved on the rod body of the rotating rod 6, so that the raw materials inside the mixing barrel 1 can be stirred, so that the raw materials inside the mixing barrel 1 can be fully reacted and mixed.

[0025] However, in reality, when the raw materials are put into the mixing equipment for mixing, the viscous paste-like mixed raw materials will adhere to the inner wall of the mixing equipment, easily forming dirt and difficult to clean. Since the ratio of various raw materials will be determined before the reaction, when the mixing equipment is used again, the dirt on its inner wall will affect the ratio of the raw materials and reduce the quality of the formed hot melt adhesive.

[0026] To solve the above problems, further referring to Figure 2 and Figure 4 As shown, the inner cavity of the mixing barrel 1 is provided with a cleaning mechanism that cooperates with the stirring mechanism;

[0027] The cleaning mechanism includes a connecting plate 12 arranged between the stirring rod and the inner wall of the mixing barrel 1, a cleaning brush 15 is vertically arranged on one side of the connecting plate 12, and the bristles of the cleaning brush 15 are closely attached to the inner wall of the mixing barrel 1, a fixing strip 13 is fixed between the other side of the connecting plate 12 and the shaft of the rotating rod 6, and a power component for controlling the swing of the cleaning brush 15 is arranged on one end of the rotating connecting rod 11;

[0028] By setting the cleaning mechanism, the rotating rod 6 and the stirring rod can drive the connecting plate 12 and the cleaning brush 15 to rotate as a whole through the fixing bar 13 while rotating and stirring the material. The cleaning brush 15 rotates in contact with the inner wall of the mixing barrel 1, which can clean the inner wall of the mixing barrel 1. At the same time, under the action of the power component, the power component can intermittently drive the cleaning brush 15 to swing. The swing of the cleaning brush 15 will cause the bristles to be twisted to a certain extent during rotation, thereby enhancing the fit between the cleaning brush 15 and the inner wall of the mixing barrel 1 and improving the cleaning effect on the inner wall of the barrel.

[0029] Further, refer to Figure 2 and Figure 3As shown, it is worth noting that the power component includes a turntable 7 fixedly sleeved on the output shaft of the motor 2 and located above the bevel gear 3, a convex block 8 is fixedly connected to the bottom surface of the turntable 7, a rotating connecting rod 11 is arranged below the turntable 7, one end of the rotating connecting rod 11 rotates and penetrates into the connecting plate 12 and is fixedly connected to the top of the cleaning brush 15, the other end of the rotating connecting rod 11 is fixedly connected to a connecting block 10, and the upper end of the connecting block 10 is fixedly connected to a transmission column 9 arranged at intervals;

[0030] Through the setting of the power component, the turntable 7 can intermittently squeeze the transmission column 9 through the protrusion 8 when rotating with the output shaft of the motor 2. When one of the transmission columns 9 is squeezed, one side of the connecting block 10 will be tilted downward, and the rotating connecting rod 11 will be driven to rotate in the tilted direction. When the turntable 7 continues to rotate and squeeze the other transmission column 9, the rotating connecting rod 11 will be driven to rotate in the tilted direction again. Under the continuous rotation of the turntable 7, the rotating connecting rod 11 can be driven to rotate back and forth left and right, so the cleaning brush 15 will swing under the action of the rotation of the rotating connecting rod 11.

[0031] Further, refer to Figure 4 As shown, it is worth noting that a U-shaped fixing frame 14 is further provided between the stirring rod and the inner wall of the mixing barrel 1, and the two ends of the fixing frame 14 are respectively fixedly connected to the two side surfaces of the connecting plate 12, and a stabilizing block 16 is fixed to the bottom end of the cleaning brush 15, and the end of the stabilizing block 16 crosses the inner side of the fixing frame 14 and is hinged to a swing bar 17 between the bottom of one side of the fixing frame 14;

[0032] By setting the fixed frame 14, the stabilizing block 16 and the swinging bar 17, when the cleaning brush 15 swings, the stabilizing block 16 will drive the swinging bar 17 to swing. The swinging bar 17 can stabilize the swinging of the cleaning brush 15 and prevent the stabilizing block 16 from shaking when swinging, thereby affecting the rotation effect of the device.

[0033] Further, refer to Figure 2 As shown, a spiral blade 20 is provided on the bottom rod of the rotating rod 6, and the spiral blade 20 penetrates into the discharge port;

[0034] By setting the spiral blade 20, when discharging, the spiral blade 20 can rotate at the discharge port along with the rotation of the rotating rod 6, so as to stir the raw materials in the discharge port, so as to make the discharge more uniform.
