[0029] like Figures 1 to 7 As shown, the utility model is a mixing and stirring device for sealant production, comprising: a mixing box 1, a cover plate 2 fitted on the top of the mixing box 1, a stirring mechanism for stirring the sealant in the inner cavity of the mixing box 1, and an opening and closing mechanism for driving the cover plate 2 to open and close;

[0030] The stirring mechanism includes: a rotating shaft installed on the side wall of the cover plate 2, a motor 6 that drives the rotating shaft to rotate, a spiral blade 8 that flips the sealant longitudinally, the spiral blade 8 is fixedly sleeved on the outer edge of the rotating shaft, a stirring blade 14 that stirs the sealant circumferentially, a scraper 16 that scrapes the sealant attached to the inner wall of the mixing box 1, the scraper 16 is fixedly installed at the bottom end of the rotating shaft, and the outer side of the scraper 16 is in contact with the inner wall of the mixing box 1, a linkage component that drives the stirring blade 14 to rotate, and a lifting component that drives the stirring blade 14 to move up and down; the linkage component includes: a linkage component that is rotatably installed on the side wall of the cover plate 2 Connecting rod 12, several connecting rods 12 are annularly evenly arranged on the side wall of cover plate 2, a driven gear 11 fixedly mounted on the top of connecting rod 12, a circular tube 13 sleeved on the outer edge of connecting rod 12, several stirring blades 14 fixedly mounted on the outer edge of circular tube 13, a driving gear 10 meshingly mounted on the outer edge of driven gear 11 and sleeved on the outer edge of rotating shaft, and several driven gears 11 are mutually meshed with driving gear 10, a limiting groove is provided on the inner wall of circular tube 13, and a limiting strip 18 fixedly mounted on the side wall of connecting rod 12 and sliding in the inner cavity of limiting groove;

[0031] When the sealant raw materials in the inner cavity of the mixing box 1 are stirred and mixed, the motor 6 is started, and the motor 6 drives the rotating shaft to rotate, and the rotating shaft drives the cylinder 7, the spiral blade 8, the scraper 16, and the driving gear 10 to rotate. The rotation of the spiral blade 8 can turn the sealant from bottom to top, so that the sealant can be stirred vertically, so that the sealant at the bottom and the top can be mixed, and the sealant is stirred evenly, thereby improving the production quality of the sealant;

[0032] At the same time, the rotation of the scraper 16 can scrape off the sealant on the side wall of the inner cavity of the mixing box 1, thereby preventing the sealant from adhering to the inner wall of the mixing box 1, further improving the uniformity of mixing, and, when discharging, preventing the sealant from remaining on the side wall of the mixing box 1, thereby playing a role in cleaning the sealant adhering to the inside of the mixing box 1, without affecting the reuse of the device;

[0033] At the same time, the driving gear 10 drives the driven gear 11 to rotate, the driven gear 11 drives the connecting rod 12 to rotate, the connecting rod 12 drives the round tube 13 to rotate, and the round tube 13 drives the stirring blade 14 to rotate, so that the sealant can be stirred in a circumferential direction, further improving the uniformity of the sealant, thereby improving the production quality of the sealant;

[0034] In addition, when the motor 6 rotates in the reverse direction, the spiral blade 8 can drive the sealant to move from top to bottom, so that the sealant actively moves toward the discharge pipe, thereby achieving the purpose of rapid discharge.

[0035] The above mechanism enables the device to stir the sealant in both the circumferential direction and the longitudinal direction, thereby improving the uniformity of stirring and further improving the production quality of the sealant.

[0036] The lifting assembly includes: a cylinder 7 fixedly mounted on the outer edge of the rotating shaft, a guide groove opened on the side wall of the cylinder 7, the guide groove is a U-shaped groove in opposite directions and interconnected, a circular plate 9 mounted on the outer edge of the cylinder 7, a circular tube 13 rotatably mounted on the side wall of the circular plate 9, and a bull's eye ball 17 rotatably mounted on the inner wall of the circular plate 9 and slidably mounted in the inner cavity of the guide groove.

[0037] By rotating the cylinder 7, the bull's eye ball 17 can be driven to move along the path of the guide groove, thereby driving the circular plate 9 to move back and forth, and the circular plate 9 drives the plurality of circular tubes 13 to move back and forth, and the circular tubes 13 drive the stirring blades 14 to move back and forth, so that the stirring blades 14 can move back and forth while rotating, thereby increasing the stirring range of the stirring blades 14, achieving both circumferential stirring of the sealant and longitudinal stirring of the sealant, thereby making the sealant evenly mixed and improving the production quality of the sealant.

[0038] The opening and closing mechanism includes: a mounting plate fixedly mounted on the side wall of the mixing box 1, a connecting plate 4 fixedly mounted on the side wall of the cover plate 2, and a cylinder 3 fixedly mounted between the mounting plate and the connecting plate 4, the bottom end of the cylinder 3 is fixedly mounted on the top of the fixing plate, and the top end of the cylinder 3 is fixedly mounted on the bottom of the connecting plate 4; when in use, first start the two cylinders 3 to drive the adjacent connecting plates 4 to move upward, and the two connecting plates 4 jointly drive the cover plate 2 to move upward, so that the mixing box 1 and the cover plate 2 are separated, thereby realizing the opening of the cover plate 2, and at this time, the sealant raw material can be put into the inner cavity of the mixing box 1. After the raw material is put in, start the two cylinders 3 to drive the adjacent connecting plates 4 to return to their original position downward, and the two connecting plates 4 jointly drive the cover plate 2 to return to their original position downward, so that the mixing box 1 and the cover plate 2 are tightly fitted, thereby realizing the closing of the cover plate 2;

[0039] The cover plate 2 can be opened or closed by the opening and closing mechanism, thereby facilitating the placement of sealant raw materials into the inner cavity of the mixing box 1, which is beneficial to the production and use of the sealant. During mixing, the mixing box 1 is sealed to prevent external air from entering the sealant and affecting the production quality of the sealant.

[0040] In addition, when the cover 2 is opened upwards and drives the stirring mechanism to move to the outside of the inner cavity of the stirring box 1, it is convenient to clean the inner wall of the stirring box 1 and the stirring mechanism to prepare for the next use.

[0041] A discharge pipe 5 is connected to the center of the bottom of the mixing box 1, and a solenoid valve is installed on the side wall of the discharge pipe 5; when the sealant is mixed, the solenoid valve is opened and the sealant can be discharged through the discharge pipe 5.

[0042] An annular groove is provided on the top of the mixing box 1, and a sealing ring 15 is fixedly installed on the bottom of the cover plate 2, and the sealing ring 15 is located in the inner cavity of the annular groove; when the cover plate 2 is closed, that is, the bottom of the cover plate 2 is tightly fitted with the top of the mixing box 1, and at this time the sealing ring 15 is located in the inner cavity of the annular groove. Through the mutual cooperation of the sealing ring 15 and the annular groove, the airtightness between the mixing box 1 and the cover plate 2 can be improved, that is, the airtightness of the sealant during mixing is improved, and the outside air is prevented from entering the sealant and affecting the production quality of the sealant.

[0043] Support legs are also fixedly installed on the outer edge of the mixing box 1. Several support legs are evenly distributed in a ring shape on the outer edge of the mixing box 1, thereby providing a stable support for the mixing box 1.

[0044] Working principle: When in use, the motor 6 drives the shaft to rotate, and the shaft drives the cylinder 7, spiral blade 8, scraper 16, and driving gear 10 to rotate. The rotation of the spiral blade 8 can flip the sealant from bottom to top, so that the sealant can be stirred longitudinally. The rotation of the scraper 16 can scrape off the sealant on the side wall of the inner cavity of the mixing box 1, avoiding the sealant from adhering to the inner wall of the mixing box 1, further improving the uniformity of stirring. The driving gear 10 drives the driven gear 11 to rotate, and then drives the stirring blade 14 to rotate, so that the sealant can be stirred longitudinally. The sealant is stirred circumferentially, which further improves the uniformity of the sealant and thus improves the production quality of the sealant. The rotation of the cylinder 7 can drive the bull's eye ball 17 to move along the path of the guide groove, thereby driving the circular plate 9 to move up and down, and then driving the stirring blade 14 to move up and down, so that the stirring blade 14 can move up and down while rotating, thereby increasing the stirring range of the stirring blade 14, realizing both circumferential stirring of the sealant and longitudinal stirring of the sealant, thereby making the sealant mixed evenly and improving the production quality of the sealant.
