DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present application embodiment discloses a hot melt adhesive mixing and stirring kettle, referring to Figure 1 , Figure 2 and Figure 3 , comprising a mounting frame 1 and a reactor body 2, the reactor body 2 being bolted to the mounting frame 1. A feeding port is provided at the top of the reactor body 2, and a discharge pipe 22 is welded at the bottom, a sealing cover 21 is installed at the feeding port, and a valve is installed on the discharge pipe 22. A vertical stirring roller 3 is rotatably connected in the reactor body 2, and a plurality of stirring blades 31 are installed on the stirring roller 3. A plurality of vertical mounting rods 4 are arranged at intervals along the circumference of the stirring roller 3, and the mounting rods 4 are arranged on the outer wall of the stirring roller 3 along the radial sliding of the stirring roller 3. A plurality of scrapers 41 for cleaning the inner wall of the reactor are arranged at intervals along the vertical direction on the mounting rod 4, a first driving member 5 for driving the stirring roller 3 to rotate is installed on the top of the reactor body 2, and a second driving member 6 for driving the mounting rod 4 to move is installed on the stirring roller 3. A heating device 7 is installed on the outer wall of the reactor body 2, and a spraying device 9 is also arranged in the reactor body 2.

[0022] In the embodiment of the present application, when the reactor body 2 is mixing and stirring the hot melt adhesive raw materials, the scraper 41 does not contact the inner wall of the reactor body 2. After the hot melt adhesive is mixed and stirred, the hot melt adhesive can be discharged by opening the valve. Subsequently, the second driving member 6 can drive the mounting rod 4 to move so that the scraper 41 can contact the inner wall of the reactor body 2, and then the first driving member 5 can be started to drive the stirring roller 3 to rotate so that the scraper 41 can scrape off the residual material on the inner wall of the reactor body 2. During the scraping process, the spray device 9 can be turned on to spray the cleaning liquid on the inner wall and internal components of the reactor body 2, further improving the cleaning effect of the inside of the reactor body 2. Compared with the traditional cleaning method, a hot melt adhesive mixing and stirring kettle of the present application does not require the staff to manually rinse the inner wall of the reactor body 2 and manually scrape the residual material on the inner wall, which has the effect of reducing labor intensity and improving cleaning efficiency.

[0023] Specifically, the heating device 7 includes a heat preservation cover 71 and a heating pipe 72. The heat preservation cover 71 is sleeved on the outer wall of the reactor body 2, and the heating pipe 72 is arranged between the heat preservation cover 71 and the reactor body 2. The heat preservation cover 71 is made of aluminum foil heat preservation cotton. The heating pipe 72 can heat the raw materials in the reactor body 2 to improve the mixing efficiency of the raw materials. After the hot melt adhesive is discharged, the heating pipe 72 can also heat the residual material on the inner wall of the reactor body 2 so that the scraper 41 can scrape the residual material.

[0024] Specifically, the first driving member 5 includes a driving motor, which is installed on the top of the reactor body 2 and is transmission-connected to the stirring roller 3 .

[0025] The second driving member 6 includes a slide column 61 and a plurality of connecting rods 62. An elastic member 8 is installed on the stirring roller 3 for driving the mounting rod 4 to move and approach the stirring roller 3. The plurality of stirring rollers 3 are horizontally arranged on the outer wall of the slide column 61 along the circumference of the slide column 61. The slide column 61 is vertically slidably connected to the bottom of the stirring roller 3. The side of the mounting rod 4 close to the stirring roller 3 is provided with an inclined surface 42 at its bottom for sliding contact with the connecting rod 62. The connecting rod 62 is used to slide vertically and contact the inclined surface 42 to drive the mounting rod 4 to move horizontally. The bottom of the reactor body 2 is threadedly connected with a screw 63 for driving the slide column 61 to move.

[0026] In the embodiment of the present application, after the hot melt adhesive in the reactor body 2 is drained, the staff can rotate the screw 63 to move the slide column 61 upward, and at the same time the connecting rod 62 moves upward and slides into contact with the inclined surface 42 on the mounting rod 4, so that the mounting rod 4 can overcome the elastic force of the elastic member 8 and move closer to the inner wall of the reactor body 2, thereby ensuring that the scraper 41 can contact the inner wall of the reactor body 2.

[0027] Furthermore, the cross section of the slide post 61 is rectangular, and a slide groove 32 for the slide post 61 to move is provided on the stirring roller 3. One end of the slide post 61 is inserted into the slide groove 32, and the other end is rotatably connected to the end of the screw rod 63 through a turntable 64. A plurality of connecting rods 62 are bolted to the outer wall of the turntable 64 at intervals. The slide post 61 is also fixed to the turntable 64 by bolt connection.

[0028] In the embodiment of the present application, the slide column 61 can rotate synchronously with the stirring roller 3. When the hot melt adhesive raw materials are mixed and stirred, the connecting rod 62 is located below the mounting rod 4, and can rotate synchronously with the stirring roller 3 and stir the raw materials at the inner bottom wall of the reactor body 2 to improve its mixing efficiency; when cleaning the inner side wall of the reactor body 2, the screw 63 can be rotated to drive the slide column 61 and the connecting rod 62 to move upward, so that the scraper 41 contacts the inner side wall of the reactor body 2.

[0029] Reference Figure 4 The elastic member 8 includes a spring 81, a mounting tube 82, and a slide bar 83 slidably disposed in the mounting tube 82. One end of the mounting tube 82 is horizontally welded to the outer wall of the stirring roller 3, and one end of the slide bar 83 is welded to the mounting rod 4. The spring 81 is disposed in the mounting tube 82, and the spring 81 is used to drive the slide bar 83 to move and approach the stirring roller 3.

[0030] In the embodiment of the present application, both ends of the spring 81 are respectively welded to the inner bottom wall of the mounting tube 82 and the slide bar 83 , so that the slide bar 83 can be driven to move and approach the stirring roller 3 through its own elastic force.

[0031] Specifically, the spray device 9 includes a water pipe 91 and a plurality of spray heads 92. The water pipe 91 is installed on the inner top wall of the reactor body 2, and one end of the water pipe 91 passes through the top of the reactor body 2 and is externally connected to a water supply tank (not shown in the figure). The water supply tank is equipped with a water pump, and the plurality of spray heads 92 are installed at intervals on the portion of the water pipe 91 located inside the reactor body 2.

[0032] In the embodiment of the present application, cleaning liquid is stored in the water supply tank, and starting the water pump can cause multiple nozzles 92 to spray the cleaning liquid. In this way, the spray range of the cleaning liquid can be increased, and the cleaning effect on the inside of the reactor body 2 can be improved.

[0033] The implementation principle of a hot melt adhesive mixing and stirring kettle in the embodiment of the present application is as follows: when the reactor body 2 mixes and stirs the hot melt adhesive raw materials, the scraper 41 does not contact the inner wall of the reactor body 2. After the hot melt adhesive is mixed and stirred, the hot melt adhesive can be discharged by opening the valve. Subsequently, the second driving member 6 can drive the mounting rod 4 to move so that the scraper 41 can contact the inner wall of the reactor body 2, and then the first driving member 5 can be started to drive the stirring roller 3 to rotate so that the scraper 41 scrapes off the residual material on the inner wall of the reactor body 2. During the scraping process, the spray device 9 can be turned on to spray the cleaning liquid on the inner wall and internal components of the reactor body 2, further improving the cleaning effect of the inside of the reactor body 2. Compared with the traditional cleaning method, the hot melt adhesive mixing and stirring kettle of the present application does not require the staff to manually rinse the inner wall of the reactor body 2 and manually scrape the residual material on the inner wall, which has the effect of reducing labor intensity and improving cleaning efficiency.
