The weighing head 40 is fixedly connected to the top of the support 33 in the cavity of the base pipe 34. The sliding groove 35 is respectively opened on the peripheral wall surfaces of the base pipe 34. The limiting frame 36 is rectangular frame-shaped, and the inner wall surface of the cavity of the limiting frame 36 is fixedly connected to the outer wall of the base pipe 34.

The limiting block 39 is fixedly connected to the bottom of the sliding rod 38. The stress column 37 is rectangular block-shaped, and the size of the stress column 37 is the same as the size of the cavity of the base pipe 34. The sliding rod 38 is respectively fixedly connected to the peripheral wall surfaces of the stress column 37. Each bottom of the sliding rod 38 is fixedly connected with a limiting block 39. The sliding rod 38 can vertically slide in the sliding groove 35. The top of the limiting block 39 can contact the bottom of the limiting frame 36 through the sliding of the sliding rod 38. The weighing structure further includes a leakage groove 42, a guiding block 43, a top frame 44, a cylinder 45, an open plate 46 and a connecting plate 47. The leakage groove 42 is penetrated and opened at the bottom of the weighing chamber 41. The guiding block 43 is fixedly connected to the inner bottom of the weighing chamber 41. The top frame 44 is fixedly connected to the inner side wall surface of the weighing chamber 41. The section of the top frame 44 is triangular. The cylinder 45 is fixedly connected to the bottom of the top frame 44. The open plate 46 is rotatably connected in the leakage groove 42. The connecting plate 47 is symmetrically fixedly connected to the top of the open plate 46.

The contraction end of the cylinder 45 is rotatably connected to the symmetric connecting plates 47. The open plate 46 can cover the leakage groove 42;
[0033] During specific use, the raw materials to be added into the cavity of the kettle body 20 are poured from the top of the weighing chamber 41. When the materials are poured into the cavity of the weighing chamber 41, the weighing chamber 41 will move downward as the weight in the cavity increases. When the weighing chamber 41 moves, it will drive the force-bearing column 37 to move downward in the cavity of the base tube 34. The force-bearing column 37 can press the contact of the weighing head 40 downward into the cavity of the housing during movement for data detection. When the force-bearing column 37 slides, it will also drive the sliding rod 38 to slide in the sliding groove 35. After the weighing head 40 weighs the materials in the cavity of the weighing chamber 41 to reach the required weight, the feeding can be stopped. At this time, because the air cylinder 45 is electrically connected to the power supply, the power supply of the air cylinder 45 is turned on. The contraction section at the bottom of the air cylinder 45 will push the open plate 46 downward through the connecting plate 47. The open plate 46 will flip in the leakage groove 42. At this time, the leakage groove 42 will be in an open state. The materials in the cavity of the weighing chamber 41 will leak out from the leakage groove 42 and enter the cavity of the kettle body 20 through the inlet groove 31. After the materials in the cavity of the weighing chamber 41 leak out completely, the air cylinder 45 will retract, driving the open plate 46 to cover the leakage groove 42 again. At this time, the power supplies of the kettle body 20 and the rotating motor 22 can be turned on. The kettle body 20 will heat the cavity when the power is turned on, and the rotating motor 22 will drive the stirring rod 23 to rotate when the power is turned on. After the raw materials in the cavity of the kettle body 20 are heated and melted, the rotating stirring rod 23 will mix the melted materials. After the stirring rod 23 finishes stirring and mixing, the valve 21 is opened, and the melted materials will leak out of the kettle body 20 when the valve 21 is opened, thus completing the production of the pressure-sensitive adhesive;
[0034] In summary, by setting the weighing structure, the materials can be directly weighed and then added when added into the cavity of the kettle body 20. The weighing structure pre-weighs the materials to be mixed through the weighing chamber 41 and directly adds the materials into the cavity of the kettle body 20 after weighing, thus effectively saving the time and energy of the workers for original weighing, and thereby reducing the heavy work pressure of the workers.
[0035] As Figure 1 、 Figure 2 and Figure 3 shown, an upper connecting block 24 is fixedly connected to the wall surface of the top cover 30, a lower connecting block 25 is fixedly connected to the outer wall surface of the kettle body 20, a bolt 26 is threadedly connected to the wall surface of the upper connecting block 24. A plurality of upper connecting blocks 24 are evenly and fixedly connected to the outer wall surface of the top cover 30. The number and position of the lower connecting blocks 25 correspond to those of the upper connecting blocks 24, and the bolt 26 can pass through the upper connecting block 24 and the lower connecting block 25;
[0036] During specific use, when it is necessary to clean the cavity of the kettle body 20, all the bolts 26 are removed from the top of the upper connecting block 24. At this time, the top cover 30 can be removed from the top of the kettle body 20. When the top cover 30 is removed, it will drive the stirring rod 23 to separate from the cavity of the kettle body 20. At this time, the top of the kettle body 20 will be in an open state, and its cavity can be cleaned. When installing the top cover 30, align the position of each upper connecting block 24 with the lower connecting block 25 and install the bolt 26 on the top of each upper connecting block 24 and tighten it;
[0037] In summary, by setting the detachable top cover 30, the time for disassembling the device when cleaning the kettle body 20 can be effectively reduced, and the open top of the kettle body 20 after the top cover 30 is removed is more conducive to cleaning the cavity, thereby reducing the time for cleaning the kettle body 20.
[0038] Working principle: Pour the raw materials to be added into the cavity of the kettle body 20 from the top of the weighing chamber 41. When pouring materials into the cavity of the weighing chamber 41, the weighing chamber 41 will move downward as the weight in the cavity increases. When the weighing chamber 41 moves, it will drive the force-bearing column 37 to move downward in the cavity of the base tube 34. The force-bearing column 37 can press the contact of the weighing head 40 downward into the cavity of the housing for data detection when moving. When the force-bearing column 37 slides, it will also drive the slide bar 38 to slide in the chute 35. After the weighing head 40 weighs the materials in the cavity of the weighing chamber 41 to reach the required weight, the feeding can be stopped. At this time, because the air cylinder 45 is electrically connected to the power supply, turn on the power supply of the air cylinder 45. The contraction section at the bottom of the air cylinder 45 will push the open plate 46 downward through the connecting plate 47. The open plate 46 will turn in the leakage groove 42. At this time, the leakage groove 42 will be in an open state. The materials in the cavity of the weighing chamber 41 will leak out from the leakage groove 42 and enter the cavity of the kettle body 20 from the inlet groove 31. After the materials in the cavity of the weighing chamber 41 leak out, the air cylinder 45 will retract to drive the open plate 46 to cover the leakage groove 42 again. At this time, turn on the power supply of the kettle body 20 and the rotating motor 22. The kettle body 20 will heat the cavity when the power supply is turned on. The rotating motor 22 will drive the stirring rod 23 to rotate when the power supply is turned on. After the raw materials in the cavity of the kettle body 20 are heated and melted, the rotating stirring rod 23 will mix the melted materials. After the stirring rod 23 finishes stirring and mixing, open the valve 21. The melted materials will leak out of the kettle body 20 when the valve 21 is opened, thus completing the production of the pressure-sensitive adhesive.

Those skilled in the art will be aware that, without departing from the spirit and scope of the present utility model, various changes or equivalent substitutions can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
