Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, specifically to a continuous feeder for plastic film raw materials. Background Technology

[0002] The production process of plastic film mainly includes raw material preparation, molding process, and post-processing. The raw materials for plastic film production are usually in the form of granules or powders and have certain plasticity and processing properties. When producing plastic film, the granular raw materials need to be transported first, and then a series of processing steps are carried out before the raw materials can be produced into plastic film.

[0003] Before being transported and processed, the raw material granules will be covered with a lot of dust due to being stored in the warehouse. In order to ensure the quality of the plastic film, the raw material granules need to be cleaned in advance. After cleaning and drying, the granules will be continuously transported and processed by the conveyor belt to finally manufacture the plastic film. However, there will still be granules that are not completely dried mixed in with the raw material granules. These granules will reduce the forming quality of the plastic film. Utility Model Content

[0004] The purpose of this invention is to provide a continuous feeder for plastic film raw materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous feeder for plastic film raw materials, comprising a conveyor belt, a plurality of mounting rods fixedly connected to the top end of the conveyor belt, a frame fixedly connected to the mounting rods, a mounting box fixedly connected to the top end of the frame, symmetrically arranged support plates fixedly connected to the top end of the mounting box, an air pump fixedly installed between the support plates, a plurality of exhaust ports fixedly connected to the bottom end of the mounting box, a plurality of electric heating wires fixedly connected inside the mounting box, a rotating rod rotatably connected inside the frame, a conveying plate fixedly connected to the rotating rod, symmetrically arranged springs fixedly connected to the top end of the bottom wall inside the frame, two support seats fixedly connected to the top end of the bottom wall inside the frame, a motor fixedly installed on the support seats, and an extrusion rod fixedly connected to the output end of the motor.

[0006] Preferably, the support plates are all L-shaped, and the air outlet of the air pump penetrates the top wall of the mounting box and is located inside the mounting box.

[0007] Preferably, the bottom ends of the exhaust ports all penetrate the top wall of the frame and are located inside the frame, and the mounting rods are all L-shaped.

[0008] Preferably, the conveyor plate is inclinedly disposed inside the frame, and the bottom end of the conveyor plate is fixedly connected to the top end of the spring.

[0009] Preferably, an anti-collision groove is provided on the bottom wall of the frame at the position corresponding to the extrusion rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the extrusion rod driven by the motor vibrates the conveyor plate, causing the raw material particles falling on the conveyor plate to vibrate and tumble up and down. Then, the hot air blown out by the exhaust port completely dries the residual moisture on the plastic particles, preventing the incompletely dried particles in the raw material particles from affecting the molding quality of the plastic film. Moreover, the overall structure is simple, highly practical, and worthy of promotion and use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figs. 1-3 This utility model provides a technical solution: a continuous feeder for plastic film raw materials, including a conveyor belt 1, a plurality of mounting rods 2 fixedly connected to the top of the conveyor belt 1, a frame 3 fixedly connected to the mounting rods 2, a mounting box 4 fixedly connected to the top of the frame 3, symmetrically arranged support plates 5 fixedly connected to the top of the mounting box 4, an air pump 6 fixedly installed between the support plates 5, a plurality of exhaust ports 7 fixedly connected to the bottom of the mounting box 4, a plurality of electric heating wires 8 fixedly connected inside the mounting box 4, a rotating rod 9 rotatably connected inside the frame 3, a conveying plate 10 fixedly connected to the rotating rod 9, symmetrically arranged springs 11 fixedly connected to the top of the bottom wall inside the frame 3, two support seats 12 fixedly connected to the top of the bottom wall inside the frame 3, a motor 13 fixedly installed on the support seats 12, and an extrusion rod 14 fixedly connected to the output end of the motor 13.

[0017] The support plates 5 are all L-shaped. The air outlet of the air pump 6 passes through the top wall of the mounting box 4 and is located inside the mounting box 4. The support plates 5 provide positional support for the air pump 6. The bottom of the exhaust ports 7 all pass through the top wall of the frame 3 and are located inside the frame 3. The mounting rods 2 are all L-shaped. The exhaust ports 7 facilitate the input of hot air into the frame 3. The conveyor plate 10 is inclined inside the frame 3. The bottom of the conveyor plate 10 is fixedly connected to the top of the spring 11. The spring 11 facilitates the reset action of the conveyor plate 10. The bottom wall of the frame 3 is provided with anti-collision grooves 15 at the position corresponding to the extrusion rod 14. When the extrusion rod 14 rotates, the anti-collision grooves 15 can provide space for the extrusion rod 14 to rotate.

[0018] Specifically, when using this invention, raw material particles can be fed into the conveyor plate 10 inside the frame 3. Then, the electric heating wire 8, motor 13, and air pump 6 are started. At this time, the air pump 6 will blow air into the installation box 4. The flowing air will form hot air after passing through the electric heating wire 8. The hot air will then be blown into the interior of the frame 3 through multiple exhaust ports 7. The hot air will blow onto the raw material particles on the conveyor plate 10. At the same time, the output end of the motor 13 will drive the extrusion rod 14 to rotate upward. The upward rotating extrusion rod 14 will squeeze the bottom end of the conveyor plate 10. The pressure on the conveyor plate 10 will drive the rotating rod 9 to rotate upward as well. The upward-rotating conveyor plate 10 also stretches the two springs 11. When the extrusion rod 14 rotates to a position where it no longer extrudes the conveyor plate 10, the conveyor plate 10 will return to its original position under the action of the two springs 11. At this time, the conveyor plate 10 has completed the up-and-down vibration action, which causes the raw material particles on the conveyor plate 10 to vibrate and turn over, so that they can more evenly bear the hot air from the inside of the installation box 4. At the same time, the vibrating conveyor plate 10 will also transport the dried particles to the conveyor belt 1. At this time, the conveyor belt 1 will continuously transport the raw material particles for processing, and finally make them into plastic film.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
