[0028] In this embodiment, the raw material is placed in the feed hopper 2, and the raw material will enter the mixing tank 1 from the feed hopper 2. When the raw material added has a certain viscosity, the raw material enters the mixing tank 1, and the first motor 5 is started. The first motor 5 drives the rotating gear 6 to rotate, the rotating gear 6 drives the gear ring 4 to rotate, the gear ring 4 drives the rotating seat 3 to rotate, the rotating seat 3 drives the installed rotating ring 7 to rotate, and the rotating ring 7 drives the scraper 8 to rotate. Since the scraper 8 is in contact with the inside of the feed hopper 2, the scraper 8 scrapes and cleans the inside of the feed hopper 2, and the cleaned raw materials will also enter the mixing tank 1 due to the effect of gravity.

[0029] More specifically, the first motor 5 can be started to make the scraper 8 scrape and clean the feed hopper 2. When the raw materials in the mixing tank 1 need to be stirred and mixed, the rotating drum 12 and the stirring shaft 10 both rotate, the stirring shaft 10 drives the first stirring rod 11 to stir the raw materials in the vertical direction, and the rotating drum 12 drives the second stirring rod 13 to stir the raw materials in the horizontal direction.

[0030] See also Figure 1-5 As an implementation method for stirring and mixing the raw materials: a second motor 14 is provided at the upper end of the mixing tank 1, and a rotating shaft 15 is provided at the driving end of the second motor 14, and the rotating shaft 15 extends into the two sleeves 9 and the rotating cylinder 12, and driving bevel gears 16 are respectively provided on the rotating shafts 15 extending into the two sleeves 9, and one end of each of the stirring shafts 10 extends into the sleeve 9 and is fixedly connected to a driven bevel gear 17 that matches the driving bevel gear 16, and a plurality of connecting rods 18 are fixedly provided on the rotating shaft 15 extending into the rotating cylinder 12, and one end of each of the connecting rods 18 is fixedly connected to the rotating cylinder 12.

[0031] Specifically, the second motor 14 is started, the second motor 14 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the two driving bevel gears 16 to rotate, the driving bevel gears 16 drive the driven bevel gears 17 to rotate, the driven bevel gears 17 drive the stirring shaft 10 to rotate, the stirring shaft 10 drives the first stirring rod 11 to rotate, and the raw materials are vertically stirred. At the same time, the rotating shaft 15 drives the rotating drum 12 to rotate through the connecting rod 18, and the rotating drum 12 drives the second stirring rod 13 to rotate, and the raw materials are horizontally stirred.

[0032] See also Figure 1-5 As an implementation method for disassembling the scraper 8: two brackets 19 are symmetrically arranged on the outer side of the rotating seat 3, each of the brackets 19 is threadedly connected with a screw 20, one end of the screw 20 passes through the bracket 19 and is rotatably connected to a fixing plate 21, one side of the fixing plate 21 is slidably connected to the bracket 19 through a track structure, a fixing rod 22 is arranged at the lower end of the fixing plate 21, and a fixing hole 23 matching the fixing rod 22 is arranged on the rotating ring 7.

[0033] Specifically, when the scraper 8 is damaged and needs to be replaced, the two screws 20 are rotated in sequence. Since the screw 20 is threadedly connected to the bracket 19, the screw 20 rotates and moves at the same time, and the screw 20 drives the fixing plate 21 to move, and the fixing plate 21 drives the fixing rod 22 to move, so that the fixing rod 22 is moved out of the fixing hole 23. Two grooves 24 are provided on the rotating ring 7. The rotating ring 7 is rotated 90 degrees so that the grooves 24 are aligned with the bracket 19, and the rotating ring 7 is pulled upward to separate the rotating ring 7 from the rotating seat 3, so that the rotating ring 7 drives the scraper 8 to be removed, and the replaced rotating ring 7 and scraper 8 can be installed using the opposite operation.

[0034] To sum up, when the overall equipment is in use:

[0035] When the feed hopper 2 needs to be cleaned, the raw materials required for the pressure-sensitive adhesive processing are placed in the feed hopper 2, and the raw materials will enter the mixing tank 1 from the feed hopper 2. When the raw materials added are of a certain viscosity, the raw materials enter the mixing tank 1, and the first motor 5 is started. The first motor 5 drives the rotating gear 6 to rotate, the rotating gear 6 drives the gear ring 4 to rotate, the gear ring 4 drives the rotating seat 3 to rotate, the rotating seat 3 drives the installed rotating ring 7 to rotate, and the rotating ring 7 drives the scraper 8 to rotate. Since the scraper 8 is in contact with the inside of the feed hopper 2, the scraper 8 scrapes and cleans the inside of the feed hopper 2, and the cleaned raw materials will also enter the mixing tank 1 due to the effect of gravity.

[0037] When the scraper 8 needs to be disassembled and replaced, the two screws 20 are rotated in sequence. Since the screw 20 is threadedly connected to the bracket 19, the screw 20 rotates and moves at the same time, and the screw 20 drives the fixed plate 21 to move, and the fixed plate 21 drives the fixed rod 22 to move, so that the fixed rod 22 moves out of the fixed hole 23. Two grooves 24 are provided on the rotating ring 7. The rotating ring 7 is rotated 90 degrees so that the grooves 24 are aligned with the bracket 19, and the rotating ring 7 is pulled upward to separate the rotating ring 7 from the rotating seat 3, so that the rotating ring 7 drives the scraper 8 to be disassembled, and the replaced rotating ring 7 and scraper 8 can be installed using the opposite operation. The entire device is controlled by a controller. Since the equipment matched with the controller is a common equipment and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be repeated here.

[0038] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
