Description

Technical Field

[0001] The present invention is a feeding device for the production of degradable plastic bags, belonging to the field of green environmental protection. Background Art

[0002] A degradable plastic bag is an environmentally friendly plastic bag that has been improved through technical means so that it can be decomposed into harmless substances (such as water, carbon dioxide, methane, etc.) by microorganisms in the natural environment (such as soil, seawater, compost, etc.) or under specific conditions. Degradable plastic bags are one of the core products of the environmental protection industry, belonging to the core track of the environmental protection material industry, and are also essential items in people's daily lives. During the production of degradable plastic bags, plastic particles need to be blown to form the required plastic film, so plastic particles need to be added to the blow molding machine.

[0003] However, currently, when feeding plastic particles, most use manual feeding, which easily causes plastic particles to accumulate. And during the process of manual material handling, it is also necessary to manually cut the original bag of raw material particles to form a discharging port, and discharge the granular raw materials along the discharging port. In this way, a single person not only needs to hold the heavy original bag, but also needs to cut the discharging port with one hand. Therefore, there is an inconvenient feeding situation, and subsequent personnel discharge the raw material particles, resulting in uneven distribution of the raw materials entering the blow molding machine, making the thickness of the produced degradable plastic bags uneven, affecting the production quality of degradable plastic bags, and reducing the quality of degradable plastic bags.

The bottom inside the crushing box 12 is open-shaped to discharge the finally crushed material into the subsequent extruder. The granular raw material is first initially crushed by the primary crushing roller 35. The crushed raw material enters the grinding shell 42, and the grinding rollers 41 cooperate to crush and grind the discharged material. The two grinding rollers 41 move relatively to complete the grinding of the raw material, and the raw material is also ground between the grinding rollers 41 and the inner wall of the grinding shell 42. Finally, it enters the inside of the circular shell 43 for final processing and crushing.

Extrusion is completed through the gap, and the discharged material is discharged along the mesh openings of the filter screen 47 to achieve the discharged crushed material. First, the two outermost arc-shaped frames 46 are fixed in the installation window 45 and fixed with screws, and then the adjacent branched arc-shaped frames 46 are installed to gradually form a large arc-shaped frame, and the discharging work is carried out in cooperation with the filter screen 47.

[0026] Refer to Figure 1, a suction plate 54 is arranged on the support frame 1 in cooperation with the auxiliary support. The inside of the suction plate 54 is cavity-shaped, and suction nozzles 55 are evenly distributed at the bottom end of the suction plate 54.

The top ends of the buffer springs 64 are fixedly provided with mounting top plates 65. The U-shaped plate 62 and the mounting top plate 65 are fixed by screws. When feeding and transporting particles, the dust suction fan 56 is turned on, and the dust on the surface of the particles is adsorbed by cooperating with the dust suction pipe 57, the suction plate 54 and the suction nozzles 55. Because the dust on the surface of the particles is light in mass and easy to disperse in the air, dust adsorption is carried out to effectively disperse the dust into the air, thereby greatly improving the working environment. Finally, the crushed particles enter the aggregation cover 61 along the corrugated pipe 60 and are finally effectively discharged into the subsequent blow molding machine from the opening at the bottom of the aggregation cover 61. The opening at the bottom of the aggregation cover 61 just corresponds to the feeding port of the blow molding machine for feeding docking. And the number of the vibration motors can be designed as multiple. By cooperating with the vibration motors and the springs, the aggregation cover 61 is effectively vibrated, and then the crushed particles are smoothly discharged into the blow molding machine, and finally the feeding work of the final particle crushing raw materials is realized.

[0027] During specific operation, the robotic arm 7 is used to grab the packaging bag containing raw material particles, lift the packaging bag above the cutting table 8, and drive the packaging bag to the cutting component in coordination with the movement of the robotic arm 7. Then, the cutting motor 9 on the cutting component is started to drive the cutting disc 10. When the cutting disc 10 rotates, it cuts the bottom of the grabbed packaging bag to form a long discharging opening at the bottom of the packaging bag. Then, in coordination with the robotic arm 7, the raw material packaging bag is moved towards the feeding box 6 while being cut. Finally, the raw material packaging bag is moved above the feeding box 6, and the internal granular raw materials are discharged into the feeding box 6 through the opening at the bottom of the raw material packaging bag. Then, the conveying roller 4 and the conveying blade 5 inside the rotary feeding cylinder 3 are started. The raw material particles enter the inside of the feeding cylinder 3 along the guiding pipeline at the bottom of the feeding box 6. Finally, the conveying blade 5 completes the conveying of the raw materials. Eventually, the raw materials enter the pulverizing box 12 along the discharging pipeline 11, replacing manual bag opening and feeding, thus reducing the labor intensity and improving the feeding efficiency. The granular raw materials are crushed by the crushing component inside the pulverizing box 12, and the crushed raw materials are discharged into the subsequent extruder for subsequent heating and melting. The crushed raw materials are beneficial to the melting of the raw materials and improve the melting efficiency of the raw materials.

[0028] Start the driving cylinder 22 to drive the pushing plate 23 to descend. The pushing plate 23 is rotatably connected to the driving rod 25 through the U-shaped seat 1. And the other end of the driving rod 25 is also rotatably connected to the grasping rod 21 through the U-shaped seat 1. Similarly, the top of the grasping rod 21 is rotatably arranged inside the setting port 20. When the pushing plate 23 moves up and down, it drives the driving rod 25 to tilt. During the tilting process, the driving rod 25 drives the end of the bent grasping rod 21 to insert into the raw material packaging bag. The pointed ends of the grasping rods 21 on both sides insert into the top inside the raw material packaging bag. Finally, cooperate with the robot arm 7 to lift the raw material packaging bag sleeved on the grasping rod 21, achieving the purpose of replacing manual handling. Then cooperate with the cutting component to cut the discharge opening of the raw material packaging bag, and discharge the internal raw material particles along the cutting discharge opening. After discharging, the set secondary pushing cylinder 31 drives the telescopic movement of the secondary pushing plate 32. The secondary pushing cylinder 31 and the pushing cylinder can be replaced with existing electric push rods. Just complete the corresponding replacement movement, and it is not limited to only setting cylinders. The telescopic movement of the secondary pushing plate 32 drives one end of the secondary fixed plate 18 to produce a reciprocating tilting movement, forming a shaking movement, driving the discharging raw material packaging bag to shake, ensuring that the particles inside the raw material packaging bag are discharged cleanly. The bottom inside the crushing box 12 is open-shaped to complete the discharge of the finally crushed material, which is discharged into the subsequent extruder. The granular raw material is first initially crushed by the preliminary crushing roller 35. The crushed raw material enters the grinding shell 42 and is crushed and ground by the grinding roller 41. The two grinding rollers 41 move relative to each other to complete the grinding of the raw material. And the raw material will also be ground between the grinding roller 41 and the inner wall of the grinding shell 42. Finally, it enters the circular shell 43 for final processing and crushing. The arc end of the grinding scraper 50 does not directly contact the filter screen 47 installed inside the circular shell 43, and there is a gap between them. Extrusion is completed through the gap, and discharge is carried out along the mesh opening of the filter screen 47 to achieve the discharge of the crushed material. First, fix the two outermost arc-shaped frames 46 in the installation window 45 with screws, then install the adjacent branch arc-shaped frames 46, gradually forming a large arc-shaped frame, and carry out the discharging work in cooperation with the filter screen 47. The crushed raw material speeds up the subsequent heating and melting, improving the melting efficiency of the raw material. Several supporting rod bodies need to be welded on the outer wall of the crushing box 12, and the supporting rod bodies are fixed to the ground, so as to avoid connecting and suspending the crushing box 12 through the feeding cylinder and the discharging pipeline.
