Description

Technical Field

[0001] This utility model relates to the technical field of plastic product processing equipment, and specifically to a debris cleaning device for plastic product processing. Background Technology

[0002] During the processing of plastic products, steps such as injection molding, extrusion, or cutting molding generate a large amount of plastic debris. If this debris is not cleaned up in a timely manner, it will not only pollute the processing environment and affect the operating accuracy of equipment, but may also cause safety hazards due to debris accumulation. Therefore, debris cleaning devices are key auxiliary equipment in plastic product processing production lines. Their main function is to collect and process plastic debris in the processing area through adsorption, collection, and filtration to maintain the cleanliness of the working environment and the stability of the equipment.

[0003] However, existing plastic debris cleaning devices still suffer from the following problems: First, traditional devices often rely on a single suction port to directly adsorb debris, but plastic debris is lightweight and easily dispersed, making it difficult to collect efficiently using only negative pressure adsorption, resulting in some debris remaining on the processing equipment's work surface. Second, the suction pipes are mostly fixed rigid pipes or irregularly shaped flexible hoses, making it difficult to adapt to the suction needs of complex processing areas and lacking flexibility. Third, the filtration structure is mostly a single-layer filter, which has low filtration efficiency and is prone to clogging, requiring frequent shutdowns for maintenance after long-term use. These problems severely restrict the practical application effectiveness of debris cleaning devices. Utility Model Content

[0004] This utility model provides a debris cleaning device for plastic product processing, which aims to solve the problems of low adsorption efficiency, poor filtration effect, insufficient flexibility and inconvenient maintenance of traditional debris cleaning devices by combining high-pressure purging and negative pressure adsorption, hierarchical filtration structure design and multi-functional component optimization.

[0005] The technical solution provided by this utility model is a debris cleaning device for plastic product processing, including a frame, a dust collection box and a dust suction fan installed on the frame. The air inlet of the dust suction fan is connected to the inside of the dust collection box. A dust suction main pipe is provided on one side of the dust collection box and communicates with the inside of the dust collection box. A dust suction head is connected to the end of the dust suction main pipe.

[0006] The frame is equipped with a high-pressure blowing system, which includes an air compressor and a high-pressure air gun connected by an air blowing pipe. The high-pressure air gun is moved to blow up the plastic debris on the worktable of the processing equipment and guide it to the adsorption area of ​​the dust suction head.

[0007] The dust collection box is equipped with a rotating first filter screen and a second filter screen located below the first filter screen. The first filter screen is located on the outside of the dust collection box and is connected to an electric motor that drives its rotation.

[0008] As a preferred technical solution of this utility model, the main suction tube is a flexible hose, and multiple shaped steel wires are embedded radially on the outer side of the main suction tube, which are fixed after the main suction tube is bent and moved to a specific position.

[0009] As a preferred embodiment of this utility model, the opening of the vacuum head is wide and flat, and its bottom edge is provided with a flexible sealing skirt.

[0010] As a preferred embodiment of this utility model, the air blowing pipe is a retractable flexible hose, and the air blowing pipe is provided with a fixed hook for hanging on the frame.

[0011] As a preferred technical solution of this utility model, the first filter screen is composed of a cross-shaped rotating frame and an independent filter screen inserted on the rotating frame, and the dust collection box is provided with an air supply hood that matches the shape of the first filter screen at the connection between the dust collection box and the dust suction main pipe.

[0012] As a preferred embodiment of this utility model, the second filter screen has a larger mesh size than the first filter screen, and the second filter screen is inclinedly arranged inside the dust collection box, with the higher end of the second filter screen located above the connection point with the dust collection fan.

[0013] As a preferred technical solution of this utility model, the top of the dust collection box is provided with a detachable cleaning cover above the first filter screen, and the cleaning cover is fastened to the top of the dust collection box by a buckle.

[0014] As a preferred technical solution of this utility model, the bottom four corners of the frame are provided with universal wheels with braking function.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. High-efficiency adsorption and purging synergy: The high-pressure air gun of the high-pressure purging system blows up the debris and guides it to the suction head. Combined with the wide-mouth flat suction head and flexible sealing skirt, the collection efficiency of debris is significantly improved, solving the problem of easy residue in traditional single negative pressure adsorption.

[0017] 2. Flexible structural design: The main suction pipe adopts a flexible hose with embedded shaped steel wire, which not only ensures the deformability of the pipe to adapt to complex working conditions, but also achieves shape fixation through the shaped steel wire; the air blowing pipe is set as a telescopic hose and equipped with a fixed hook, which is convenient for storage and fixation, and improves the space adaptability of the device.

[0018] 3. Staged filtration and self-cleaning function: The first filter screen consists of a cross-shaped rotating frame and an independent filter screen. Driven by an electric motor, it uses centrifugal force to separate and transfer debris to the second filter screen, avoiding clogging of the single-layer filter screen. The second filter screen adopts a high mesh count and inclined setting to further improve the filtration accuracy and promote debris sliding, thus extending the cleaning cycle.

[0019] 4. Convenient maintenance design: The top of the dust collection box is equipped with a removable cleaning cover, which can be quickly opened and closed through a snap-fit ​​connection, making it easy to clean or replace the filter components; the bottom of the frame is equipped with casters with brakes, which significantly improves the mobility of the device and adapts to the cleaning needs of different processing stations.
