[0001] This utility model relates to the field of papermaking equipment technology, specifically a roller-type bulk packaging machine. Background Technology

[0002] In recent years, recycled waste paper pulp has been widely used as a papermaking raw material. To facilitate transportation, waste paper is usually compressed, bundled, and transported using balers. Before use, the paper bales must be dispersed. The traditional rotary drum unpacking machine works by feeding the bales of waste paper into a rotating drum. The inner wall of the drum is welded with structures such as cones and spiral blades. After entering the drum, the paper bales are continuously lifted and dropped, and transported to the discharge port through the internal spiral structure. During the continuous falling motion, the paper bales disperse. Although this type of unpacking machine has a simple structure, it has defects such as large footprint, high power consumption, small processing capacity, low level of intelligence, and uneven unpacking. Summary of the Invention

Several blades 33 are fixedly connected to the outer wall of the bulk packaging roller 32. The main shaft 31 is rotatably connected to the main frame 1 through the bearings. The bulk packaging roller 32 is octagonal prism in shape, and the blades 33 on two adjacent outer wall surfaces of the bulk packaging roller 32 are arranged alternately.

[0035] It also includes a first chain conveyor 11 and a second chain conveyor 12, wherein the end of the conveying path of the first chain conveyor 11 is located in front of the bulk packaging roller 3, and the beginning of the conveying path of the second chain conveyor 12 is located below the bulk packaging roller 3.

[0036] A bearing frame 13 is fixedly connected to the main frame 1, and the bearing is mounted on the bearing frame 13.

[0037] The laser displacement sensor 10 and the cylinder 8 are respectively connected to the PLC control system. The PLC control system receives the paper pack height data from the laser displacement sensor 10, calculates the control command for the cylinder 8, and sends the control command to the cylinder 8.

[0038] The geared motor 9 is a hollow shaft geared motor. The bulk packaging roller 3 is located between the main frame 1 and the upper frame 2. The main frame 1 is welded from square tubing, and a fixed base is fixedly connected to the main frame 1. The geared motor 9 is fixedly connected to the fixed base. The upper frame 2 is welded from square tubing and steel plate, and the upper frame 2 is fixed to the upper end of the main frame 1 by bolts.

[0039] The roller-type bulk packaging machine in this embodiment mainly includes a main frame 1, a pressing device, a bulk packaging roller 3, an upper frame 2, a reduction motor 9, a chain conveyor, and other parts.

[0040] The main frame 1 is made of square tubes welded together. The geared motor 9 is mounted on the main frame 1 through a fixed seat. The upper frame 2 is fixed above the main frame 1 by bolts. The loose packaging roller 3 is set on the main frame 1 through a bearing bracket 13.

[0041] The upper frame 2 is welded from square tubing and steel plate. It is bolted to the upper part of the main frame 1. The unpacking roller 3 is positioned between the upper frame 2 and the main frame 1 to block dust and other contaminants during unpacking. A cylinder mounting bracket 7 is installed on the upper frame 2, and cylinders 8 are fixed to it via this bracket. The other end of cylinder 9 is connected to the pressing mechanism. A pulley guide rail 6 is also installed on the upper frame 2, and the pressing mechanism is mounted on it via this guide rail.

The pressing mechanism also includes a cylinder 8, which is fixed to a cylinder mounting bracket 7 on the upper frame 2. The bulk packaging machine is equipped with a laser displacement sensor 10 (FLR-1000-UI), positioned near the pressing mechanism of the roller bulk packaging machine. The laser displacement sensor 10 is installed above the first chain conveyor 11 and is connected to the PLC control system. When the first chain conveyor 11 delivers the paper package 14, the height of the delivered paper package 14 can be detected in advance. When the laser displacement sensor 10 receives the height of the paper package 14, it transmits the signal to the control computer. After the computer calculates, it will control the cylinder 8 to work and automatically adjust the height of the pressing mechanism so that the pressing mechanism can press the paper package 14 tightly, which facilitates the unpacking roller 3 to decompose the paper package 14 (pressing mechanism control logic: when the height of the paper package 14 is detected to be X, the cylinder 8 will control the pressing mechanism to lift X+50mm).

[0043] The unpacking roller 3 mainly includes blades 33, unpacking roller 32, connecting discs 34, and main shaft 31. The blades 33 have a specific structural design that easily grips the paper packages, effectively lifting the paper packages 14 fed by the first chain conveyor 11. At this time, the pressing mechanism automatically adjusts its height to precisely press down on the paper packages 14 fed by the first chain conveyor 11. Simultaneously, the lifting action of the blades 33 achieves the unpacking effect. The unpacking roller 32 adopts an octagonal prism structure, with four or three different numbers of blades 33 installed on adjacent sides. The blades 33 on adjacent sides are arranged in a staggered sequence to maximize unpacking efficiency. The main shaft 31 passes through the unpacking roller 32. A connecting disc 34 is designed on each side of the unpacking roller 32. The unpacking roller 32 is locked to the main shaft 31 via the connecting discs 34 and round nuts 35. The unpacking roller 3 is connected to the main frame 1 via bearings and bearing brackets 13 on the main shaft 31.

[0044] The equipment is powered by a hollow shaft geared motor. The main shaft 31 passes through the hollow shaft of the geared motor 9 for connection. The hollow shaft geared motor is fixed to the main frame 1 by a fixed seat.

[0045] Working principle: The equipment works in conjunction with two chain conveyors. The first chain conveyor 11 delivers paper packages 14 and pushes them forward. The pressing mechanism senses the height of the paper package 14 in advance through the laser displacement sensor 10 and automatically adjusts the height of the pressing mechanism so that it just presses the paper package 14. When the paper package 14 touches the rotating loosening roller 3, the blades 33 on the loosening roller 3 lift and push the paper package 14. At this time, combined with the downward pressure of the pressing mechanism, the paper package 14 can be easily dispersed. The dispersed material falls onto the second chain conveyor 12 and is sent to the subsequent process.
