Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a hot melt adhesive product extruder with a stirring structure. Background Technology

[0002] Hot melt adhesive is a type of adhesive that bonds by melting it through heating. It features rapid curing, ease of use, and environmental friendliness. It is primarily composed of ethylene-vinyl acetate copolymer resin, which is copolymerized under high temperature and pressure, resulting in excellent adhesion, water resistance, and temperature resistance.

[0003] According to the description in the patent application CN 220331914U, "This utility model discloses a hot melt adhesive extruder, relating to the field of hot melt adhesive processing technology. It includes a support base, an I-beam mounting frame above the support base, a feed hopper connected to the top of the I-beam mounting frame, a second drive motor installed inside the I-beam mounting frame, a first lead screw connected to one side of the second drive motor, a support frame connected to the outside of the first lead screw, a third drive motor installed inside the support frame, a second lead screw connected above the third drive motor, a lead screw nut connected to the outside of the second lead screw, a fourth drive motor fixed to the bottom of the lead screw nut, and a cleaning brush roller connected below the fourth drive motor. This utility model automatically cleans the inner wall of the feed hopper using the cleaning brush roller, solving the problems of time-consuming and labor-intensive manual cleaning of the feed hopper and low automation in existing technologies, thereby further improving work efficiency."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model uses a fourth drive motor to rotate the cleaning brush roller to clean the dirt inside the feed hopper. However, when using the brush for cleaning, the brush comes into contact with the hot melt adhesive remaining at the feed inlet when it contacts the inner wall of the feed hopper. The stickiness of this hot melt adhesive increases the resistance of the brush, causing the brush bristles to fall off and stick to the inner wall of the feed inlet. When hot melt adhesive is poured in later, the cleaning bristles will follow the hot melt adhesive into the device and be squeezed, affecting the quality of the extruded hot melt adhesive. Therefore, it is necessary to improve the hot melt adhesive product extruder with a stirring structure to solve the above problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 -9. This utility model provides an embodiment: a hot melt adhesive product extruder with a stirring structure, including a mounting plate 1, a stirring tank 21, and an extrusion mechanism. A support leg 4 is fixedly connected to the bottom of the mounting plate 1, and the extrusion mechanism is located at the bottom of the mounting plate 1. The stirring tank 21 is fixedly connected inside the mounting plate 1, and a rotating disk 22 is rotatably connected inside the stirring tank 21. A first fixing plate 23 is fixedly connected to the bottom of the rotating disk 22, and a cleaning plate 24 is fixedly connected to the outside of the first fixing plate 23. The cleaning plate 24 replaces the brush for cleaning. During the cleaning process, the hot melt adhesive enters the mixing tank 21 and is thoroughly mixed before being extruded through the extrusion mechanism. When it is necessary to clean the inside of the mixing tank 21, the rotating disk 22 rotates, which in turn drives the cleaning plate 24 to rotate via the first fixed plate 23. The cleaning plate 24 then contacts the inner wall of the mixing tank 21, causing impurities to detach from the inner wall. The mixing tank 21 has a groove at a position relative to the rotating disk 22. The rotating disk 22 is rotatably connected to the inside of the groove, which restricts the rotation of the rotating disk 22 and prevents it from moving and detaching from the mixing tank 21.

[0027] Please see Figure 1 - Figure 6In this embodiment, a first motor 25 is connected to the top of the mixing tank 21. A first gear 26 is fixedly connected to the output end of the first motor 25. The first gear 26 is rotatably connected inside the mixing tank 21. A rotating disk 22 meshes with the outside of the first gear 26. A first rotating rod 27 is rotatably connected inside the rotating disk 22. A second gear 28 is fixedly connected to the top of the first rotating rod 27. A stirring rod 29 is fixedly connected to the outside of the first rotating rod 27. A feed inlet 210 is fixedly connected inside the mixing tank 21. A fixed gear 211 is fixedly connected to the outside of the feed inlet 210. The second gear 28 meshes with the outside of the fixed gear 211. A heating wire body 212 is provided. By setting the heating wire body 212 and the stirring rod 29, the hot melt adhesive inside the mixing tank 21 is kept active and prevented from cooling and solidifying. There are four first rotating rods 27 and four second gears 28. The four first rotating rods 27 are symmetrically rotated and connected inside the mixing tank 21. The four second gears 28 are respectively fixedly connected to the top of the four first rotating rods 27, and the four second gears 28 are all meshed with the outside of the fixed gear 211. Through the cooperation of the four second gears 28 and the fixed gear 211, the first rotating rods 27 are driven to rotate while the rotating disk 22 rotates, so that the stirring rod 29 continues to stir the hot melt adhesive inside the mixing tank 21.

[0028] Please see Figure 2 , Figure 7 - Figure 9In this embodiment, the extrusion mechanism includes a first outer casing 31, which is fixedly connected to the bottom of the mixing tank 21. A second motor 32 is fixedly connected to the left side of the first outer casing 31. A threaded rod 33 is fixedly connected to the output end of the second motor 32. The threaded rod 33 is rotatably connected inside the first outer casing 31. A transmission wheel 34 is fixedly connected to the outside of the threaded rod 33. A transmission belt 35 is driven to the outside of the transmission wheel 34. A sliding seat 36 is threadedly connected to the outside of the threaded rod 33. The sliding seat 36 is slidably connected inside the first outer casing 31. A scraper 37 is fixedly connected to the bottom of the sliding seat 36. A collection box 38 is slidably connected inside the first outer box 31. A telescopic rod 39 is fixedly connected to the outside of the first outer box 31. A first fixing buckle 310 is fixedly connected to the top of the telescopic rod 39. A sliding rod 311 is slidably connected inside the first outer box 31. A connecting rod 312 is rotatably connected between the first fixing buckle 310 and the sliding rod 311. A second fixing buckle 313 is fixedly connected to the outside of the sliding rod 311. An opening and closing plate 314 is fixedly connected to the top of the second fixing buckle 313. 4. A sliding connection is made inside the first outer casing 31. An extrusion cylinder 315 is fixedly connected to the bottom of the first outer casing 31. A third motor 316 is fixedly connected to the left side of the extrusion cylinder 315. A spiral blade 317 is fixedly connected to the output end of the third motor 316. The spiral blade 317 is rotatably connected inside the extrusion cylinder 315. An extrusion die body 318 is threadedly connected to the outside of the extrusion cylinder 315. By opening and closing the opening and closing plate 314, it is prevented that impurities fall into the extrusion cylinder 315 during cleaning and affect the heat of subsequent extrusion work. Regarding the quality of the melt adhesive, the first outer box 31 has a groove at a position opposite to the sliding seat 36. The sliding seat 36 is slidably connected inside the groove. By sliding the sliding seat 36, the scraper 37 is driven to clean the impurities falling on the opening and closing plate 314, so that they fall into the collection box 38 for centralized storage. The first outer box 31 has a groove at a position opposite to the sliding rod 311. The sliding rod 311 is slidably connected inside the groove. The sliding rod 311 is restricted from sliding by the groove. Then, by the cooperation between the sliding rod 311 and the groove, the opening and closing plate 314 is driven to open and close.

[0029] During operation, hot melt adhesive enters the mixing tank 21 through the feed inlet 210. The first motor 25 drives the first gear 26 to rotate. The first gear 26, in conjunction with the rotating disk 22, drives the first rotating rod 27 inside to rotate, simultaneously rotating the first fixed plate 23. This causes the cleaning plate 24 to contact the inner wall of the mixing tank 21, preventing the hot melt adhesive from adhering to it. The heating wire body 212 provides heat to the inside of the mixing tank 21, while the stirring rod 29 stirs the adhesive, keeping it active and preventing it from cooling down. The hot melt adhesive inside the mixing tank 21 falls through the first outer casing 31 into the extrusion cylinder 315. The third motor 316 drives the spiral blades 317 to rotate, propelling the hot melt adhesive forward through the extrusion die body 31. When the material is squeezed out and cleaning is required, the telescopic rod 39 passes through and cooperates with the connecting rod 312 through the first fixing buckle 310, driving the sliding rod 311 to slide inside the first outer box 31. The sliding rod 311 drives the opening and closing plate 314 through the second fixing buckle 313, thereby closing it. After the opening and closing plate 314 is closed, the rotating disk 22 rotates, driving the cleaning plate 24 to clean the impurities attached to the inner wall of the mixing tank 21, so that they are separated from the mixing tank 21. After the impurities fall, they fall to the top of the opening and closing plate 314. At this time, the second motor 32 works, and the transmission wheel 34 cooperates with the transmission belt 35 to make the threaded rods 33 on both sides rotate, thereby driving the sliding seat 36 to slide inside the first outer box 31. At this time, the scraper 37 contacts the surface of the opening and closing plate 314 to clean the impurities on the opening and closing plate 314 and pushes them into the collection box 38 for centralized storage.

[0030] By adding a rotating disc 22, a first fixing plate 23, and a cleaning plate 24 through the above steps, the problem of residual hot melt adhesive causing the cleaning bristles and brush to fall off during cleaning is solved, thus affecting the quality of subsequent hot melt adhesive.
