[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1-6 , an embodiment provided by the present invention: including a hot melt placement tank 1, support legs 2 are fixedly installed at the bottom of the hot melt placement tank 1, a screening mesh 3 is slidably installed inside the hot melt placement tank 1, a screening filter plate 4 located at the bottom of the screening mesh 3 is fixedly installed inside the hot melt placement tank 1, a hot melt placement bucket 5 is arranged in the hot melt placement tank 1, a heating component 6 for heating the hot melt placement bucket 5 is arranged at the bottom of the inner wall of the hot melt placement tank 1, a moving component 7 for driving the screening mesh 3 to move is arranged inside the hot melt placement tank 1, and a hollow funnel 8 is fixedly installed inside the hot melt placement tank 1. First, the plastic to be hot melted is placed inside the hot melt placement tank 1. At this time, the plastic will fall inside the screening mesh 3. Then, the plastic on the screening mesh 3 can be shaken off through the moving component 7. At this time, the larger plastic will fall onto the screening filter plate 4, and the smaller plastic will fall into the hot melt placement bucket 5 from the screening filter plate 4. Since the screening filter plate 4 is inclined, the larger plastic on the screening filter plate 4 will be discharged through the hot melt placement tank 1. At this time, the plastic inside the hot melt placement bucket 5 can be heated and melted by the heating component 6.

[0033] Refer to Figures 1-6, the heating component 6 includes a U-shaped heat insulation sleeve 61, the bottom of the U-shaped heat insulation sleeve 61 is fixedly installed on the bottom of the inner wall of the hot melt placement tank 1, a heating coil 62 is fixedly installed on the bottom of the inner wall of the U-shaped heat insulation sleeve 61, the top of the U-shaped heat insulation sleeve 61 is detachably installed with a heat conducting copper plate 63 through bolts, the bottom of the heat conducting copper plate 63 contacts the top of the U-shaped heat insulation sleeve 61, the bottom of the heat conducting copper plate 63 contacts the top of the heating coil 62, and the top of the heat conducting copper plate 63 contacts the bottom of the hot melt placement barrel 5. Through the mutual cooperation of the U-shaped heat insulation sleeve 61, the heating coil 62 and the heat conducting copper plate 63, when the plastic enters the inside of the hot melt placement barrel 5, the heating coil 62 can be powered on at this time. The heating coil 62 being powered on can heat the heat conducting copper plate 63, and the heat conducting copper plate 63 being heated can heat the bottom of the hot melt placement barrel 5, and at this time, the plastic can be gradually melted.

[0034] Refer to Figures 1-6, the moving component 7 includes a rotating cam block 71. One side of the hot-melt placement tank 1 is fixedly installed with a placement plate 72. The top of the placement plate 72 is fixedly installed with a driving motor 73. The output end of the driving motor 73 penetrates into the interior of the hot-melt placement tank 1 and is rotatably installed with the hot-melt placement tank 1. The output end of the driving motor 73 is fixedly installed with the left side of the rotating cam block 71. Through the mutual cooperation of the rotating cam block 71, the placement plate 72, and the driving motor 73, when the driving motor 73 is started, it can drive the rotating cam block 71 to rotate. The rotation of the rotating cam block 71 drives the screening net 3 to move downward. The downward movement of the screening net 3 can shake the plastics on its top, causing them to enter the hot-melt placement barrel 5. Inside the hot-melt placement tank 1, a fixed ring 74 is fixedly installed. Four groups of return springs 75 are fixedly installed on the top of the fixed ring 74. The tops of the return springs 75 are fixedly installed with the bottom of the screening net 3. Through the mutual cooperation of the fixed ring 74 and the return springs 75, the fixed ring 74 can always bear the elastic force of the return springs 75. Thus, when the screening net 3 moves to the bottommost position downward, under the action of the return springs 75, the screening net 3 will be reset. Four groups of limiting rods 9 are fixedly installed at the bottom of the screening net 3. The limiting rods 9 are located inside the return springs 75. The bottoms of the limiting rods 9 penetrate to the bottom of the fixed ring 74 and are slidably installed with the fixed ring 74. A limiting block 10 is fixedly installed at the bottom of the limiting rod 9. The top of the limiting block 10 contacts the bottom of the fixed ring 74. Through the mutual cooperation of the limiting rods 9 and the limiting block 10, the screening net 3 can be limited to prevent the screening net 3 from twisting when moving upward, resulting in instability when the screening net 3 is reset. The right side of the hot-melt placement tank 1 is communicated with a discharge pipe 11. A receiving hopper 12 is detachably installed on the right side of the hot-melt placement tank 1. Through the mutual cooperation of the discharge pipe 11 and the receiving hopper 12, plastics with a larger screening filter plate 4 can enter the feed hopper through the discharge pipe 11, so as to store the discharged plastics into the receiving hopper 12. The bottom of the right side of the hot-melt placement tank 1 is communicated with a discharge pipeline 13. A discharge valve 14 is communicated with the surface of the discharge pipeline 13. Through the mutual cooperation of the discharge pipeline 13 and the discharge valve 14, the hot-melted plastics can enter the interior of the discharge pipeline 13. At this time, the discharge valve 14 can be rotated to discharge the hot-melted plastics in the discharge pipe 11.

[0035] Working principle: When it is necessary to melt the plastic, the plastic to be hot-melted can be placed inside the hot-melt placement tank 1 at this time. The plastic will fall inside the screening mesh 3. Then, the driving motor 73 can be started. The output shaft of the driving motor 73 drives the rotating cam block 71 to rotate. The rotation of the rotating cam block 71 drives the screening mesh 3 to move downward. The downward movement of the screening mesh 3 can shake the plastic on its top. When the screening mesh 3 moves downward, it compresses the return spring 75. The downward movement of the screening mesh 3 can drive the limit rod 9 and the limit block 10 to move downward, so as to limit the screening mesh 3. At this time, the shaken plastic will fall on the screening filter plate 4. At this time, the smaller plastic will fall into the hot-melt placement bucket 5 from the screening filter plate 4. Since the screening filter plate 4 is inclined, the larger plastic on the screening filter plate 4 will enter the feed hopper through the discharge pipe 11, so that the discharged plastic can be stored in the receiving hopper 12. When all the plastic enters the hot-melt placement tank 1, the heating coil 62 can be powered on at this time. The power-on of the heating coil 62 can heat the heat-conducting copper plate 63. The heating of the heat-conducting copper plate 63 can heat the bottom of the hot-melt placement bucket 5. At this time, the plastic can be gradually hot-melted. After the plastic is hot-melted, the hot-melted plastic enters the discharge pipeline 13. At this time, the discharge valve 14 can be rotated to discharge the hot-melted plastic in the discharge pipe 11, thus achieving the advantage of hot-melting the plastic.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
