Description

Technical Field

[0001] This utility model relates to the technical field of plastic feeding for packaging bags, and in particular to a plastic feeding device for packaging bags. Background Technology

[0002] Plastic packaging bags are bags made of plastic as raw material and used to produce various daily necessities. They are widely used in daily life and industrial production.

[0003] In the production of plastic packaging bags, plastic granules need to be heated to a molten state by an extruder before being extruded again. Currently, the feed hopper of the extruder is designed with a larger top and a smaller bottom. After a large amount of plastic granules are injected, the feed pipe is prone to blockage during the feeding process through the feed pipe into the extruder's feed port, which affects the normal feeding of plastic granules and makes it impractical. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a plastic feeding device for packaging bags that can effectively prevent blockage of the feeding pipe, ensure normal feeding of plastic granules, and improve practicality.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0018] Please see Figures 1-4 This utility model discloses a plastic feeding device for packaging bags, comprising an extruder 1 and a fixed base 5. An extruder motor 2 is installed at the right end of the extruder 1. A feeding pipe 3 is fixedly connected to the top of the extruder 1 at the feeding port. A feeding hopper 4 is integrally connected to the top of the feeding pipe 3. The fixed base 5 is fixedly installed on the top of the extruder 1, and a motor 6 is fixedly installed at the top of the fixed base 5. A drive shaft 7 is rotatably installed through the feeding pipe 3, and the output end of the motor 6 is fixedly connected to the front end of the drive shaft 7. Multiple sets of stirring rods 8 are symmetrically and equidistantly fixedly connected to the outer wall of the drive shaft 7, and the multiple sets of stirring rods 8 are located in the feeding pipe 3. A bracket 9 is fixedly connected to the top of the extruder 1, and a fixed shaft 10 is fixedly installed on the bracket 9. A support arm 11 is rotatably sleeved on the fixed shaft 10. A spherical rubber hammer 12 is fixedly connected to the end of the support arm 11 away from the fixed shaft 10. A transmission assembly is provided between the support arm 11 and the drive shaft 7. The transmission assembly includes a transmission crankshaft 13. Support plates 14 are symmetrically fixedly connected to both the front and rear ends of the bracket 9. The transmission crankshaft 13 is rotatably installed. On both sets of support plates 14, synchronous pulleys 15 are fixedly sleeved at the rear ends of the drive shaft 7 and the drive crankshaft 13. Synchronous belts 16 are sleeved on the two sets of synchronous pulleys 15. A drive rod 17 is rotatably sleeved on the drive crankshaft 13. A clearance groove is opened at the top of the drive rod 17, and the top of the drive rod 17 is rotatably connected to the support arm 11. In use, plastic granules are added into the feed hopper 4 and enter the extruder 1 through the feed pipe 3. During feeding, by starting the motor 6, the stirring rod 8 can be used to stir the plastic granules entering the feed pipe 3. The material particles are agitated, and the support arm 11 can be continuously oscillating, causing the support arm 11 to drive the spherical rubber hammer 12 to continuously strike the outer wall of the feed hopper 4. The vibration generated by the striking prevents the plastic particles from adhering to the inner wall of the feed hopper 4 and the discharge pipe 3. Thus, with the continuous agitation of the stirring rod 8 and the continuous striking of the spherical rubber hammer 12, the plastic particles are smoothly fed into the extruder 1, thereby effectively preventing the discharge pipe from easily getting blocked, ensuring the normal feeding of plastic particles, and improving practicality.

[0019] The feed hopper 4 is equipped with a cover assembly, which includes a material cover 18. A connector 19 is fixedly connected to the bottom outer wall of the material cover 18. Two sets of supports 20 are fixedly connected to the right outer wall of the feed hopper 4. The connector 19 is rotatably fitted onto the supports 20. The material cover 18 is rotatably fitted onto the feed hopper 4 through the cooperation of the connector 19 and the supports 20. When no material is being fed, the material cover 18 can be placed on the feed hopper 4 to prevent external debris from entering the feed hopper 4. When feeding material, the material cover 18 can be opened.

[0020] A handle 21 is fixedly connected to the top of the material cover 18 on the side away from the connector 19; by setting the handle 21, the material cover 18 can be opened and closed more conveniently.

[0021] The top of the extruder 1 is fixedly connected to a vertical plate 22, and the transmission crankshaft 13 is rotatably mounted on the vertical plate 22. By setting the vertical plate 22, the end of the transmission crankshaft 13 near the synchronous pulley 15 can be supported, thereby further ensuring the smooth rotation of the transmission crankshaft 13.

[0022] The left and right ends of the bracket 9 are fixedly connected to the top of the extruder 1 with reinforcing plates 23; by setting the reinforcing plates 23, the connection between the bracket 9 and the extruder 1 can be made more firm and stable.

[0023] This utility model discloses a plastic feeding device for packaging bags. In operation, plastic granules are added to the feeding hopper 4 and enter the extruder 1 through the discharge pipe 3. During feeding, the motor 6 is started, driving the transmission shaft 7 to rotate. The transmission shaft 7 drives the stirring rod 8 to agitate the plastic granules entering the discharge pipe 3. The transmission shaft 7, through the synchronous pulley 15 and synchronous belt 16, drives the transmission crankshaft 13 to rotate. The transmission crankshaft 13, through the transmission rod 17, drives the support arm 11 to swing, which in turn drives the spherical rubber hammer 12 to swing. The swinging of the spherical rubber hammer 12 continuously strikes the outer wall of the feeding hopper 4. The vibration generated by this striking prevents the plastic granules from adhering to the inner walls of the feeding hopper 4 and the discharge pipe 3. Thus, with the continuous agitation of the stirring rod 8 and the continuous striking of the spherical rubber hammer 12, the plastic granules smoothly enter the extruder 1.

[0024] The plastic feeding device for packaging bags of this utility model has common mechanical installation, connection and setting methods. As long as it can achieve the beneficial effect, it can be implemented. The motor 6 of the plastic feeding device for packaging bags of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.
