Description

Technical Field

[0001] This utility model relates to the technical field of plastic film production equipment, and in particular to a feeding device for a plastic film blowing machine. Background Technology

[0002] Plastic film refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins. The function of a blown film machine is to heat and melt plastic particle raw materials and then blow them into plastic films.

[0003] Before the plastic granules are fed into the blown film machine, the workers first mix different types of plastic granules according to a certain ratio, and then add the mixed granules to the feed end of the blown film machine. However, when adding the raw materials, it is not convenient for the workers to control the amount of raw materials added to the feed end of the blown film machine per unit time. If the amount of plastic raw materials added per unit time varies too much, it will affect the quality of the blown plastic film produced later. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding device for a plastic film blowing machine, which solves the problem of difficulty in controlling the amount of plastic granules added when adding raw materials to the blowing machine.

[0005] According to an embodiment of this utility model, a feeding device for a plastic film blowing machine includes: a box body, a screw conveyor assembly, and a material distribution seat. The box body has a mixing chamber and a material distribution chamber arranged sequentially from top to bottom. The top of the mixing chamber is open, and the mixing chamber and the material distribution chamber are connected. A mixing assembly is arranged inside the mixing chamber. A first motor for driving the mixing assembly to rotate is arranged on the side wall of the box body. The material distribution seat is rotatably arranged inside the box body via a rotating shaft. A second motor for driving the rotating shaft to rotate is arranged on the side wall of the box body. The material distribution seat is located at the communication position between the mixing chamber and the material distribution chamber, and is used to seal the communication between the mixing chamber and the material distribution chamber. At least one receiving groove is arranged on the side wall of the material distribution seat. A support frame is arranged at the bottom of the box body. The screw conveyor assembly is mounted on the support frame. The screw conveyor assembly is connected to the bottom of the material distribution chamber via a receiving pipe. The output end of the screw conveyor assembly is used to connect to the feed end of the blowing machine.

[0006] Compared with the prior art, this utility model has the following advantages: By setting a mixing chamber and a dispensing chamber inside the box, the mixing component in the mixing chamber mixes the raw material particles for plastic film production evenly. The dispensing seat is driven by a second motor to rotate at a constant speed. When the receiving groove of the dispensing seat is aligned with the mixing chamber, the raw material in the mixing chamber enters the receiving groove. The dispensing seat continues to rotate. When the receiving groove is aligned with the dispensing chamber, the raw material in the receiving groove falls into the dispensing chamber under its own gravity and is transported to the screw conveyor assembly through the receiving pipe. The screw conveyor assembly transports the raw material to the feeding end of the blown film machine. By controlling the second motor to drive the dispensing seat to rotate regularly, quantitative feeding is achieved.

[0007] Furthermore, the material distribution seat is disc-shaped, and the inner wall of the material distribution chamber of the material distribution seat is dynamically sealed.

[0008] Furthermore, the screw conveyor assembly includes a conveying cylinder and a screw conveyor shaft. The conveying cylinder is fixed on the support frame, and one end of the conveying cylinder is open away from the housing. The screw conveyor shaft is rotatably disposed inside the conveying cylinder and extends along the axial direction of the conveying cylinder. A third motor for driving the screw conveyor shaft to rotate is provided on the side wall of the support frame. The receiving pipe is connected to the conveying cylinder.

[0009] Furthermore, the bottom of both the mixing chamber and the dispensing chamber is inverted conical, and the receiving pipe is connected to the lowest end of the dispensing chamber.

[0010] Furthermore, the stirring assembly includes: a stirring shaft and a plurality of stirring rods disposed on the side wall of the stirring shaft, the stirring shaft being rotatably disposed within the stirring chamber, and the output end of the first motor being connected to the stirring shaft.

[0011] Furthermore, a top cover is provided at the top opening of the mixing chamber for sealing it.

[0012] Furthermore, the bottom of the top cover is provided with an insert block, and the top of the housing is provided with a slot for inserting the insert block. Attached Figure Description

The top of the stirring chamber 2 is open, and the stirring chamber 2 and the material distribution chamber 3 are connected. The stirring assembly is arranged inside the stirring chamber 2. A first motor 4 for driving the stirring assembly to rotate is arranged on the side wall of the box body 1. The material distribution seat 5 is rotatably arranged inside the box body 1 through a rotating shaft 6. A second motor for driving the rotating shaft 6 to rotate is arranged on the side wall of the box body 1. The material distribution seat 5 is located at the communication position between the stirring chamber 2 and the material distribution chamber 3. The material distribution seat 5 is used to block the communication between the stirring chamber 2 and the material distribution chamber 3. At least one receiving groove 7 is arranged on the side wall of the material distribution seat 5. A support frame 8 is arranged at the bottom of the box body 1. The screw conveyor assembly is installed on the support frame 8. The screw conveyor assembly is connected to the bottom of the material distribution chamber 3 through a receiving pipe 9. The output end of the screw conveyor assembly is used to connect with the feeding end of the blowing machine.

[0017] By setting a mixing chamber 2 and a dispensing chamber 3 inside the housing 1, the mixing component in the mixing chamber 2 mixes the raw material granules for plastic film production evenly. The dispensing seat 5 is driven by a second motor to rotate at a constant speed. When the receiving groove 7 of the dispensing seat 5 is aligned with the mixing chamber 2, the raw material in the mixing chamber 2 enters the receiving groove 7. The dispensing seat 5 continues to rotate. When the receiving groove 7 is aligned with the dispensing chamber 3, the raw material in the receiving groove 7 falls into the dispensing chamber 3 under its own gravity and is transported to the screw conveyor assembly through the receiving pipe 9. The screw conveyor assembly transports the raw material to the feed end of the blown film machine. By controlling the second motor to drive the dispensing seat 5 to rotate regularly, quantitative feeding is achieved.

[0018] Specifically, the material distribution seat 5 is disc-shaped, and the inner wall of the material distribution chamber 3 of the material distribution seat 5 is dynamically sealed; the screw conveyor assembly includes a conveying cylinder 10 and a screw conveyor shaft 11.

The screw conveyor shaft 11 is driven to rotate by the third motor 16. During the rotation, the screw conveyor shaft 11 conveys the raw material in the conveying cylinder 10 toward the open end of the conveying cylinder 10.

[0019] In one embodiment, the bottom of both the mixing chamber 2 and the dispensing chamber 3 is inverted conical, and the receiving pipe 9 is connected to the lowest end of the bottom of the dispensing chamber 3, so as to facilitate the discharge of raw materials in the mixing chamber 2 and the dispensing chamber 3 and prevent any raw materials from being left at the bottom of the dispensing chamber 3 and the mixing chamber 2.

[0020] In one embodiment, the stirring assembly includes: a stirring shaft 12 and a plurality of stirring rods 13 disposed on the side wall of the stirring shaft 12.
