[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. It is popular because the product itself is solid, easy to package, transport, store, solvent-free, pollution-free, non-toxic; and has the advantages of simple production process, high added value, high bonding strength, and fast speed.

[0003] During the production and processing of hot melt adhesive, the adhesive liquid needs to be fully mixed and stirred using a stirring device. Existing hot melt adhesive stirring devices usually use a single motor to drive a single stirring paddle to stir the hot melt adhesive; however, the hot melt adhesive has a high viscosity, and a single stirring paddle is difficult to quickly form a large vortex, which will lead to the problem of long mixing and stirring time; a single stirring paddle has a large load during long-term stirring, which can easily cause the stirring paddle to deform. Utility Model Content

[0006] Preferably, the driving assembly includes a motor A and a motor B fixedly installed above the mixing barrel, a sprocket A fixedly arranged on the mixing shaft B, and a sprocket B fixedly arranged on the output shaft of the motor B. The output shaft of the motor A is fixedly connected to the mixing shaft A, and the sprocket A and the sprocket B are connected via a chain transmission.

[0007] Preferably, the stirring plate A and the stirring plate B are provided with a liquid passage groove extending through the front and back, and reinforcing columns are cross-fixed inside the liquid passage groove. The stirring plate A and the stirring plate B are fixed with a plurality of triangular blocks on one side close to the stirring barrel.

[0008] Preferably, a support plate is fixedly provided inside the mixing barrel, a socket is provided on the top wall of the support plate, the bottom of the mixing shaft A is inserted into the socket and is rotatably connected to the support plate through a bushing, a plurality of support columns are fixedly provided below the sprocket A, a ball is provided below the support column, and the ball is rollingly connected to the top wall of the mixing barrel.

[0009] Preferably, the outside of the mixing barrel is wrapped with a heating belt.

Since the stirring shaft B is located above the stirring plate A, the stirring plate B will mix and stir the hot melt adhesive in the upper half of the mixing barrel, and the stirring plate A will mix and stir the hot melt adhesive in the lower half of the mixing barrel. Since the stirring shaft A is inserted into the rotating hole and connected to the stirring shaft through the bushing B is rotatably connected (the bushing is fixedly connected to the stirring shaft A), the stirring shaft A and the stirring shaft B do not interfere with each other during rotational motion, and can rotate simultaneously. The stirring plates A and B can quickly form a vortex during rotational motion, thereby shortening the mixing and stirring time. Since the stirring plates B and A respectively mix and stir the upper and lower parts of the hot melt adhesive in the mixing barrel, they share the load and prevent deformation.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-4As shown, the utility model discloses a hot melt adhesive stirring device, including a stirring barrel 1, a support frame 2 fixedly arranged below the stirring barrel 1, a feed pipe 3 and an air outlet pipe 4 fixedly arranged above the stirring barrel 1, and a discharge pipe 5 fixedly arranged below the stirring barrel 1, a stirring assembly is arranged inside the stirring barrel 1, and a driving assembly is arranged above the stirring barrel 1, the stirring assembly includes a stirring shaft A6 and a stirring shaft B7 rotatably arranged inside the stirring barrel 1, and a plurality of stirring plates A8 and a stirring plate B9 respectively fixedly arranged on the stirring shaft A6 and the stirring shaft B7, the stirring shaft B7 is located above the stirring plate A8, and a rotating hole 10 is opened through the stirring shaft B7 from top to bottom. After the stirring shaft A6 is inserted into the rotating hole 10, it is rotatably connected to the stirring shaft B7 through a bushing 11, and the stirring shaft A6 and the stirring shaft B7 are both connected to the driving assembly. When the utility model is used, the valve 28 is first closed to close the discharge pipe 5, and then the lid 27 is opened to pour the hot melt adhesive particles and various additives into the feed pipe 3 to enter the mixing barrel 1, and the heating belt 24 is started to heat the mixing barrel 1. After the temperature of the mixing barrel 1 rises, the hot melt adhesive particles will melt into liquid, and the motor A12 and the motor B13 are started to drive the stirring shaft A6 and the stirring shaft B7 to rotate. The stirring shaft A6 and the stirring shaft B7 drive the stirring plate A8 and the stirring plate B9 to rotate. Since the stirring shaft B7 is located above the stirring plate A8, the stirring plate B9 will mix and stir the hot melt adhesive in the upper half of the mixing barrel 1, and the stirring plate A8 will mix and stir the hot melt adhesive in the lower half of the mixing barrel 1. Since the stirring shaft A6 is inserted into the rotating hole 10 and then passes through the bushing 11 It is rotatably connected to the stirring shaft B7 (the bushing 11 is fixedly connected to the stirring shaft A6). The stirring shaft A6 and the stirring shaft B7 do not interfere with each other during rotation and can rotate simultaneously. The stirring plates A8 and B9 can quickly form a vortex during rotation, thereby shortening the mixing and stirring time. Since the stirring plates B9 and A8 respectively mix and stir the upper and lower parts of the hot melt adhesive in the mixing barrel 1, they share the load and prevent deformation. In summary, the utility model has the beneficial effects of shortening the mixing and stirring time and preventing the deformation of the stirring plate, and solves the problem that the viscosity of the hot melt adhesive is relatively large, and a single stirring paddle is difficult to quickly form a large vortex, resulting in a long mixing and stirring time; and the single stirring paddle has a large load during long-term stirring, which easily causes the stirring paddle to deform.

[0020] Preferably, the driving assembly includes a motor A12 and a motor B13 fixedly mounted above the mixing barrel 1, a sprocket A14 fixedly mounted on the mixing shaft B7, and a sprocket B15 fixedly mounted on the output shaft of the motor B13. The output shaft of the motor A12 is fixedly connected to the mixing shaft A6, and the sprocket A14 and the sprocket B15 are connected by a chain 16. Since the output shaft of the motor A12 is fixedly connected to the mixing shaft A6, it is convenient to drive the mixing shaft A6 to rotate; since the sprocket A14 and the sprocket B15 are connected by a chain 16, it is convenient to drive the mixing shaft B7 to rotate.

[0021] Preferably, the stirring plate A8 and the stirring plate B9 are provided with a liquid trough 17 through the front and back, and the liquid trough 17 is cross-fixed with a reinforcing column 18, and the stirring plate A8 and the stirring plate B9 are fixedly provided with a plurality of triangular blocks 19 on the side close to the mixing barrel 1. Since the reinforcing columns 18 are cross-fixed inside the liquid trough 17, the strength of the stirring plate A8 and the stirring plate B9 is strengthened to prevent deformation; since the stirring plate A8 and the stirring plate B9 are fixedly provided with a plurality of triangular blocks 19 on the side close to the mixing barrel 1, the triangular blocks 19 provide shear force during rotation, and the shear force cuts the hot melt adhesive, which is beneficial to the mixing and stirring of the hot melt adhesive.

After the bottom of the mixing shaft A6 is inserted into the plug hole 21, it is rotatably connected to the support plate 20 through the bushing 11. A plurality of support columns 22 are fixedly arranged below the sprocket A14, and a ball 23 is provided below the support column 22, and the ball 23 is rollingly connected to the top wall of the mixing barrel 1. Since a plurality of support columns 22 are fixedly arranged below the sprocket A14, and a ball 23 is provided below the support column 22, and the ball 23 is rollingly connected to the top wall of the mixing barrel 1, it plays a role in supporting the mixing shaft B7.

[0024] Preferably, an elastic pad 25 is fixedly arranged above the air outlet pipe 4, and the elastic pad 25 is provided with a fine groove 26. Since the elastic pad 25 is provided with a fine groove 26, when the internal air pressure of the mixing barrel 1 is high, the gas will rush out from the fine groove 26, thereby exhausting the gas.

[0025] Preferably, a cover 27 is provided above the feed pipe 3, and a valve 28 is fixedly installed on the discharge pipe 5. Since the cover 27 is provided above the feed pipe 3, it prevents external impurities from falling into the mixing barrel 1; since the valve 28 is fixedly installed on the discharge pipe 5, it facilitates the material removal.
