Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts, in particular to a negative pressure suction type chain plate chip conveyor. Background Art

[0002] Chain plate chip conveyors are mainly used in the mechanical parts manufacturing industry to collect and transport metal waste chips (this invention is mainly aimed at situations where long chips and debris are mixed) generated during machine tool processing to designated chip collection boxes, and to filter the used cutting fluid for recycling. The mainstream method on the market is to use ordinary chain plate chip conveyors to transport long chips and debris. Due to their weak filtering capacity, such chip conveyors have the following defects: in the case of liquid processing, they need to be used in conjunction with water tanks and external filters, which occupy a large area and have a large cost of use; they often lead to serious accumulation of chips inside the water tank, increasing the workload of on-site personnel; if the external filter is damaged, a large amount of debris will flow into the water tank, causing the water pump suction port on the water tank to be blocked or even damaged.

[0014] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Please refer to 1-3, an embodiment of the present invention is provided: a negative pressure suction chain plate chip conveyor, comprising a conveying frame 1, the conveying frame 1 is divided into three sections, including a horizontal section of the feeding area, an inclined lifting area, and a chip removal area for discharging. The lifting area and the chip removal area of ​​the conveying frame 1 are both provided with baffles, a reduction motor 2 is fixedly provided on one side of the conveying frame 1, the output shaft of the reduction motor 1 is fixedly connected to the driving shaft 3, the driving shaft 3 is rotatably connected to the conveying frame 1, below the driving shaft 3, there is a driven shaft 4 rotatably connected to the conveying frame 1, the driving shaft 3 and the driven shaft 4 are both fixedly connected to a sprocket 5, a spiral cavity 6 is provided on the conveying frame 1, and a spiral cavity 6 is provided inside the spiral cavity 6. The spiral body 7 has one side that passes through the conveying frame 1. The spiral body 7 is connected to the driven shaft 4 through a chain. The driving shaft 3 is driven to rotate by the reduction motor 2. The driven shaft 4 is driven by the chain plate kit 8, thereby driving the spiral body 7 to rotate, scraping the waste chips and discharging the waste chips from one side. The conveying frame 1 is provided with a chain plate kit 8. The chain plate interlayer of the chain plate kit 8 is fixedly provided with a partition 9 in the conveying frame 1. A scraper 10 is provided on the chain plate of the chain plate kit 8. The conveying frame 1 is fixedly connected to a wedge-shaped filter box 11. The wedge-shaped filter box 11 filters the waste liquid. The wedge-shaped filter box 11 is connected to the self-priming pump 12 through a pipe, so that the liquid enters the self-priming pump 12.

[0016] A copper brush is fixed on the inner surface of the chain plate of the chain plate kit 8. During the operation of the chain plate kit 8, the copper brush continuously scrapes the filter screen on the wedge-shaped filter box 11 to reduce the frequency of filter screen clogging. An overflow hole is provided on the chain plate of the chain plate kit 8. Large-sized chips are intercepted on the surface of the chain plate kit 8, and small-sized chips and liquid flow into the upper and lower chain plate interlayers through the gaps and overflow holes of the chain plate kit 8; the conveying frame 1 is provided with a main chip drop port at one end of the reduction motor 2, and small-sized chips are discharged from the main chip drop port.

[0017] A liquid level gauge is fixedly provided on one side of the conveying frame 1. When the liquid level gauge triggers a high liquid level alarm, the self-priming pump 12 sucks the wedge-shaped filter box 11 through a pipeline. A spiral chip outlet is provided on the conveying frame 1, located on one side of the spiral cavity 6 and below the spiral cavity 6. A visual window is provided on the conveying frame 1.

[0018] Working principle: The chip-liquid mixture generated by machine tool processing enters this equipment from the feeding area, and the reduction motor 2 is started to drive the driving shaft 3 to rotate, so that the chain plate kit 8 moves. The large-sized chips are intercepted on the surface of the chain plate kit 8, and the small-sized chips and liquid flow into the upper and lower chain plate interlayers through the gaps and overflow holes of the chain plate kit 8. The large-sized chips are finally discharged from the main chip drop port. The small-sized chips on the partition 9 will enter the spiral cavity 6 and then be transported and discharged by the spiral body 7. The liquid will first enter the wedge-shaped filter box 11 to filter the liquid, and then be sucked out and discharged by the self-priming pump 12. The chips on the wedge-shaped filter box 11 are washed by the copper brush, moved, and finally enter the spiral cavity 6.
