Description

Technical fields:

[0001] This application relates to the field of blow molding machine technology, and in particular to an online scrap recycling device for hollow blow molding machines. Background technology:

[0002] Current recycling methods mostly involve cooling the scrap material, crushing it in a shredder, and then mixing it with plastic granules for reuse. If a large amount of cooled, crushed material is mixed with plastic granules, the bulk density of the raw material in the main extruder hopper will decrease, causing greater fluctuations in the extrusion pressure and instability in the extrusion process, which will have a certain impact on the quality of the finished product. If the scrap material is not cooled, it is more likely to get stuck in the shredder, affecting the normal operation of the shredder. Utility model content:

[0003] To solve the above-mentioned technical problems, this utility model provides an online scrap recycling device for hollow blow molding machines. The technical problems it solves are: uncooled scrap is easily stuck in the crusher; and cooled scrap, when crushed and used, negatively impacts the quality of the finished product. The technical solution adopted by this utility model to solve these problems is as follows:

[0004] An online scrap recycling device for hollow blow molding machines includes:

[0005] Blow molding machine, with an elevator installed on one side;

[0006] The extruder is located on the upper part of the blow molding machine frame, and the extruder's hopper is located below the discharge end of the elevator;

[0007] The screen changer and the neck are connected. One end of the screen changer is connected to the extruder outlet, and the other end is connected to the neck. The other end of the neck is connected to the barrel of the extrusion screw transition section of the blow molding machine.

[0008] The heater is fitted onto the outer wall of the neck.

[0009] Furthermore, the elevator is an inclined belt conveyor.

[0010] Furthermore, the screen changing plate of the screen changer is a single-hole closable screen changing plate.

[0011] The beneficial effects of this utility model are: the elevator can transport the scrap material to the scrap extruder hopper, and after being heated and melted by the extruder, it can be directly transported to the base system of the blow molding machine for recycling. The recycling process is faster, more efficient, more stable and more reliable, reducing the impact of scrap material on product quality and improving the yield rate. Attached image description:

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0019] The online scrap recycling device for blow molding machines includes a blow molding machine 1. A lift 6 and an extruder 4 are installed on one side of the blow molding machine 1. The extruder 4 is located on the upper part of the blow molding machine 1 frame. The hopper 5 of the extruder 4 is located below the discharge end of the lift 6. A screen changer 3 is installed at the discharge port of the extruder 4. The other end of the screen changer 3 is connected to a machine neck 2. The other end of the machine neck 2 is connected to the barrel of the extrusion screw transition section of the blow molding machine 1. A heater 7 is fitted on the outer wall of the machine neck 2. The lift can transport the scrap to the scrap extruder hopper. After being heated and melted by the extruder, it is directly transported to the base system of the blow molding machine for recycling. This recycling process is faster, more efficient, stable, and reliable, reducing the impact of scrap on product quality and improving the yield rate.

[0020] It should be noted that the elevator 6 is an inclined belt conveyor, which directly transports the scraps trimmed by the workers to the extruder 4.

[0021] It should be noted that the screen changing plate of screen changer 3 is a single-hole closable screen changing plate, which means that one of the feed holes of the dual-channel screen changing plate is removed. When the extruder stops, it can be switched to this station to close the extruder channel without affecting the normal operation of the blow molding machine extrusion system.

[0022] The working principle and process of this utility model are as follows:

[0023] The still-warm scraps trimmed by the workers are placed on the inclined belt conveyor 6 and conveyed to the hopper 4 to enter the extruder 4. After being heated and melted, the screen changer 3 is switched to a passable state. The molten scraps are extruded through the extruder and then pass through the screen changer 3 and the neck 2 into the barrel of the extrusion screw transition section of the blow molding machine 1, where they are mixed with the molten material in the blow molding machine.

[0024] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "left," "right," "front," "rear," "lower left," "upper right," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
