[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution: an automatic feeding device for bubble film production, comprising a device body 1, a feeding port 2 is provided on the surface of the device body 1, a discharge pipe 3 is connected to one side of the surface of the device body 1, a gravity sensor 4 is embedded inside the device body 1, a heating box 5 is connected to one side of the surface of the device body 1, a vibrating screen mechanism 6 is provided inside the device body 1, and a drying mechanism 7 is provided inside the heating box 5;

[0020] The vibrating screening mechanism 6 includes a placement box 601, a first hollow round block 602, a spring 603, a second hollow round block 604, a sieve plate 605 and a vibration motor 606.

When polyethylene particles need to be screened, the polyethylene particles are first poured into the interior of the device body 1 through the feed port 2, and then the polyethylene particles will fall on the top of the sieve plate 605. At the same time, Start the vibration motor 606, which will drive the sieve plate 605 to vibrate through the elastic action of the spring 603. The spring 603 is limited by adding the first hollow round block 602 and the second hollow round block 604 to reduce the metal fatigue of the spring 603. Then the polyethylene particles are screened by the sieve plate 605. Since the sieve plate 605 is inclined, the polyethylene particles will roll toward the placement box 601 along the inclination angle of the sieve plate 605. During the rolling process of the particles, small particles fall directly from the screen on the sieve plate 605, while large particles roll into the inside of the placement box 601 for collection for subsequent use. Through this screening function, the size of the particles supplied to the next workstation is ensured to be just right, which speeds up the melting speed and improves production efficiency.

[0021] Furthermore, one end of the spring 603 is embedded in the first hollow round block 602, and one end of the first hollow round block 602 is embedded in the second hollow round block 604. Through the arrangement of the first hollow round block 602 and the second hollow round block 604, when in use, the cooperation of the first hollow round block 602 and the second hollow round block 604 can prevent the spring 603 from twisting and deforming left and right, effectively avoiding metal fatigue of the spring 603, thereby increasing the service life of the spring 603.

[0022] Furthermore, one end of the spring 603 is fixedly connected to the sieve plate 605, and the sieve plate 605 is inclined and located inside the device body 1.

[0023] Furthermore, the drying mechanism 7 includes a first motor 701, a second motor 702, a heating wire 703, a connecting pipe 704, a first connecting rod 705, a second connecting rod 706, an exhaust block 707, a stirring plate 708 and a fan blade 709. The first motor 701 is installed on one side of the surface of the device body 1, the second motor 702 is installed on the surface of the heating box 5, the heating wire 703 is embedded in the interior of the heating box 5, and the connecting pipe 704 is sealed on one side of the surface of the heating box 5. One end of the first motor 701 is connected to the first connecting rod 705, one end of the second motor 702 is connected to the second connecting rod 706, one end of the connecting pipe 704 is sealed to the exhaust block 707, one end of the first connecting rod 705 is connected to the stirring plate 708, and one end of the second connecting rod 706 is connected to the fan blade 709. The plate 708 and the fan blade 709 are set. When in use, the second motor 702 is first started, and then the second motor 702 drives the fan blade 709 to rotate through the second connecting rod 706. Then the rotation of the fan blade 709 will generate wind speed, and at the same time, the heating wire 703 is energized, and the heating wire 703 generates heat, which will heat the wind generated by the fan blade 709. The heated wind is input into the air intake and exhaust block 707 through the connecting pipe 704, and then discharged through the holes on the surface of the exhaust block 707. Then the first motor 701 is started, and the first motor 701 drives the first connecting rod 705 to rotate, and the first connecting rod 705 drives the stirring plate 708 to rotate, and then the rotating stirring plate 708 will stir the polyethylene particles. At the same time, the hot air blown out by the exhaust block 707 can make the polyethylene particles heated evenly, improve the drying and preheating effect, and the dried polyethylene particles automatically enter the next processing step through the discharge pipe 3. By drying the polyethylene particles, the quality of the later polyethylene products is guaranteed.

[0024] Furthermore, the exhaust block 707 is a hollow porous structure, and the exhaust block 707 is provided with six groups. Through the setting of the exhaust block 707, when in use, when hot air enters the interior of the exhaust block 707 through the connecting pipe 704, since the exhaust block 707 is a hollow porous structure, the hot air can enter the interior of the device body 1 through the holes on the surface of the exhaust block 707, thereby facilitating the subsequent drying and preheating of the polyethylene.

[0025] Furthermore, one end of the second motor 702 passes through the heating box 5 and is connected to the second connecting rod 706. Three groups of stirring plates 708 are provided.

At the same time, start the vibration motor 606, and the vibration motor 606 will drive the screen plate 605 to vibrate through the elastic action of the spring 603. By adding the first hollow round block 602 and the second hollow round block 604, the spring 603 is limited to reduce the metal fatigue of the spring 603. Then, the polyethylene particles are screened through the screen plate 605. Because the screen plate 605 is inclined, the polyethylene particles will roll toward the placement box 601 with the inclination angle of the screen plate 605. In the process of particle rolling, small particles fall directly from the screen on the screen plate 605 and fall onto the surface of the gravity sensor 4 for weighing, while large particles roll into the interior of the placement box 601 for collection, and then the second motor is started. 702, and then the second motor 702 drives the fan blade 709 to rotate through the second connecting rod 706, and then the rotation of the fan blade 709 will generate wind speed, and at the same time, the heating wire 703 is energized, the heating wire 703 generates heat, and will heat the wind generated by the fan blade 709, and the heated wind is input into the air intake and exhaust block 707 through the connecting pipe 704, and then discharged through the holes on the surface of the exhaust block 707, and then the first motor 701 is started, the first motor 701 drives the first connecting rod 705 to rotate, the first connecting rod 705 drives the stirring plate 708 to rotate, and then the rotating stirring plate 708 will stir the polyethylene particles, and at the same time, with the hot air blown out by the exhaust block 707, the polyethylene particles can be heated evenly, and the drying preheating effect is improved. The dried polyethylene particles automatically enter the next processing step through the discharge pipe 3, and the quality of the later polyethylene products is guaranteed by drying the polyethylene particles.
