The spring in the telescopic plate is squeezed, and the telescopic plate enters the fixed frame 2. At this time, a gap is formed in the collection frame, so that the plastic raw materials originally in the collection frame are poured into the feeding port from the gap, thereby achieving the purpose of automatic feeding, avoiding the need for staff to use ladders and other auxiliary tools for feeding, and reducing the difficulty and risk of feeding.

At this time, the two abutment plates are located at both ends of the notch. The abutment plates can restrain the raw materials from being dispersed, so that the raw materials can only be poured between the two abutment plates. Therefore, the plastic raw materials can accurately enter the inside of the feeding port. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The embodiment of the present application provides a plastic melting device for processing plastic products, which effectively solves the technical problem that when a worker needs to feed materials into the plastic melting device for processing plastic products, due to the high position of the feeding port, the worker needs to lift it up with force or use auxiliary tools such as ladders to perform the feeding operation, which increases the difficulty and risk of feeding. The collection frame is filled with plastic raw materials to be melted, and the worker starts the motor, and the motor drives the short rod and the driving sprocket to rotate. At this time, since the two driven sprockets and the driving sprocket are both engaged and connected with the synchronous chain, the driven sprocket will drive the threaded rod to rotate synchronously. Since the two lifting columns do not rotate, the lifting columns will drive the collection frame to move vertically upward in parallel until the two abutment plates abut the telescopic plate. At this time, the telescopic plate does not move while the collection frame and the fixed frame 2 continue to rise, the spring in the telescopic plate is squeezed, and the telescopic plate enters the fixed frame 2. At this time, a gap is formed in the collection frame, so that the plastic raw materials originally in the collection frame are poured into the feeding port from the gap, so as to achieve the purpose of automatic feeding, avoid the need for the worker to use auxiliary tools such as ladders to feed, and reduce the difficulty and risk of feeding.

The staff starts the motor 16, and the motor 16 drives the short rod 13 and the driving sprocket 14 to rotate. At this time, since the two driven sprockets 12 and the driving sprocket 14 are meshed with the synchronous chain 9, the driven sprocket 12 will drive the threaded rod 8 to rotate synchronously. Since the two lifting columns 7 do not rotate, the lifting columns 7 will drive the collection frame 4 to move vertically upward in parallel until the two abutment plates 6 abut against the telescopic plates 18.

[0032] A groove is provided at the front end of the collection frame 4, the telescopic plate 18 is located in the groove, the fixed frame 20 is located at the lower end of the telescopic plate 18, the fixed frame 20 is fixedly connected to the inner wall of the collection frame 4, the telescopic plate 18 is movably sleeved with the fixed frame 20, and two slots are provided inside the telescopic plate 18. The telescopic plate 18 is movably sleeved with the limiting column 22 through the two slots. The upper surfaces of the two limiting columns 22 are fixedly connected with springs 21. The inner wall of the fixed frame 20 is fixedly connected with two connecting rods 23 corresponding to the positions of the limiting columns 22. The lower surface of the telescopic plate 18 is provided with two The two connecting rods 23 pass through the hole 19 and are fixedly connected with the corresponding limit column 22. At this time, the telescopic plate 18 does not move while the collecting frame 4 and the fixed frame 20 continue to rise. The spring 21 in the telescopic plate 18 is squeezed, and the telescopic plate 18 enters the fixed frame 20. At this time, a gap is formed in the collecting frame 4, so that the plastic raw materials originally in the collecting frame 4 are poured into the feeding port 2 from the gap, thereby achieving the purpose of automatic feeding, avoiding the need for staff to use ladders and other auxiliary tools for feeding, and reducing the difficulty and risk of feeding.

[0033] The collecting frame 4 is located between the two threaded rods 8, and both ends of the collecting frame 4 are fixedly connected with lifting columns 7. The upper surfaces of the two lifting columns 7 are penetrated with threaded grooves 17, and the two lifting columns 7 are threadedly sleeved with the corresponding threaded rods 8 through the threaded grooves 17. The lower surface of the top plate 3 is fixedly connected to the upper surfaces of the two threaded rods 8, and the two connecting columns 5 are fixedly connected to the lower surface of the top plate 3. The two abutment plates 6 correspond to the positions of the two connecting columns 5, and the upper surfaces of the two abutment plates 6 are fixedly connected to the lower surfaces of the two connecting columns 5. The two abutment plates 6 are located at the upper end positions of the telescopic plates 18.

At this time, the two abutment plates 6 are located at the two end positions of the notch. The abutment plates 6 can constrain the raw materials from being dispersed, so that the raw materials can only be poured between the two abutment plates 6, so that the plastic raw materials can accurately enter the inside of the feeding port 2.

[0035] The collecting frame 4 is filled with the plastic raw materials to be melted, and the staff starts the motor 16. The motor 16 drives the short rod 13 and the driving sprocket 14 to rotate. At this time, since the two driven sprockets 12 and the driving sprocket 14 are meshed and connected with the synchronous chain 9, the driven sprocket 12 will drive the threaded rod 8 to rotate synchronously. Since the two lifting columns 7 do not rotate, the lifting columns 7 will drive the collecting frame 4 to move vertically upward in parallel until the two abutment plates 6 abut the telescopic plates 18. At this time, the telescopic plates 18 do not move, while the collecting frame 4 and the fixed frame 20 continue to rise, and the springs 21 in the telescopic plates 18 are squeezed. The telescopic plate 18 enters the interior of the fixed frame 20. At this time, a gap is formed in the collecting frame 4, so that the plastic raw materials originally in the collecting frame 4 are poured into the feeding port 2 from the gap, thereby achieving the purpose of automatic feeding, avoiding the need for staff to use auxiliary tools such as ladders for feeding, and reducing the difficulty and risk of feeding. When the two abutment plates 6 are against the telescopic plate 18, the raw materials in the collecting frame 4 are poured out from the gap. At this time, the two abutment plates 6 are located at the two ends of the gap. The abutment plates 6 can restrain the raw materials from dispersing, so that the raw materials can only be poured between the two abutment plates 6, so the plastic raw materials can accurately enter the interior of the feeding port 2.
