Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, specifically to a dust removal system for a strut forming machine. Background Technology
[0002] In transformer manufacturing, support bars, as crucial insulating structural components supporting the coils, are typically made from materials such as cardboard and epoxy fiberglass cloth through stamping or molding processes. During the support bar forming process, especially in steps like cutting, punching, and grinding, a large amount of fine fibrous dust and particulate matter is generated. This dust not only accumulates inside the equipment, affecting the precision of mechanical operation, but may also remain suspended in the workshop air, posing a hazard to the respiratory system of operators and even a certain explosion risk, thus impacting production safety. Currently, most support bar forming equipment is not equipped with a complete dust removal system, or only uses simple exhaust devices for dust treatment. Traditional dust removal methods are insufficient to effectively capture the fine dust generated during processing, causing some dust to diffuse into the workshop environment and affect air quality.
[0003] Therefore, existing technologies need further development. Utility Model Content

[0021] According to an embodiment of this utility model, a dust removal system for a strut forming machine is provided. Please refer to [link / reference]. Figures 1 to 2The system includes: a molding machine body 1, which has a first processing section and a second processing section; and a dust removal component 2, which is disposed on the molding machine body 1 and has a first dust removal section and a second dust removal section.

The beneficial effects of this solution are that it achieves zoned control of dust sources, avoids cross-contamination of dust from different processing areas, effectively improves local dust capture efficiency, and significantly reduces the path of dust diffusion inside the equipment.
[0023] Please refer to Figure 1 The dust removal assembly 2 includes: a first dust removal box 3, which has a first dust removal space and a first dust outlet 4 and a first dust inlet communicating with the first dust removal space; the first dust inlet is located at the bottom of the first dust removal box 3, and the first processing part is located in the first dust removal space; a second dust removal box 5, which has a second dust removal space and a second dust outlet 6 and a second dust inlet communicating with the second dust removal space; the second dust inlet is located at the bottom of the second dust removal box 5, and the second processing part is located in the second dust removal space; the second dust removal box 5 and the first dust removal box 3 are spaced apart along the width direction of the molding machine body 1; and a negative pressure pipe 7, which is connected to the first dust outlet 4 and the second dust outlet 6 through pipelines.
[0024] By adopting the above technical solution, the first dust collection box 3 and the second dust collection box 5 are directly aligned with the processing area below through the first and second dust inlets at their bottoms, and the dust from the two dust collection boxes is centrally sucked out using the negative pressure pipe 7. The beneficial effects of this solution are that the bottom dust inlet design fully utilizes the gravity settling characteristics of dust to enhance the initial capture effect, the two dust collection boxes are spaced apart along the width direction to make reasonable use of the equipment space layout, and the design of the single negative pressure pipe 7 simplifies the system structure and reduces energy consumption.
[0025] Furthermore, the negative pressure pipe 7 is connected to an external fan, which generates negative pressure inside the negative pressure pipe 7.
[0026] The dust removal system for this support bar forming machine can be installed inside a large dust removal workshop. It is connected to the negative pressure pipeline 7 through the dust extraction and filtration equipment in the large dust removal workshop to achieve dust removal for the support bar forming machine.
[0027] Please refer to Figure 2The first dust collection box 3 includes: a first rectangular cylinder 8 extending vertically; and a first suction duct 9 disposed on the first rectangular cylinder 8, the first rectangular cylinder 8 and the first suction duct 9 forming a first dust collection space; the second dust collection box 5 includes: a second rectangular cylinder 10 extending vertically; and a second suction duct 11 disposed on the second rectangular cylinder 10, the second rectangular cylinder 10 and the second suction duct 11 forming a second dust collection space.
[0028] By adopting the above technical solution, the first dust collection box 3 is formed by the vertically extending first rectangular cylinder 8 and the first suction duct 9 mounted on it, together forming the first dust collection space. The second dust collection box 5 is formed by the vertically extending second rectangular cylinder 10 and the second suction duct 11 mounted on it, together forming the second dust collection space. The beneficial effects of this solution are that the vertical rectangular cylinder structure provides a larger dust settling volume and prolongs the residence time of dust in the dust collection space. The setting of the suction duct optimizes the distribution and guidance of negative pressure airflow. At the same time, the modular box structure design facilitates the disassembly, assembly, and maintenance of the system.
[0029] Please refer to Figure 2 The cross-sectional area of the first suction cylinder 9 gradually decreases from bottom to top; the first dust outlet 4 is located at the top of the first suction cylinder 9; the cross-sectional area of the second suction cylinder 11 gradually decreases from bottom to top; the second dust outlet 6 is located at the top of the second suction cylinder 11.
[0030] By adopting the above technical solution, the cross-sectional area of the first suction duct 9 is designed to gradually decrease from bottom to top, and a first dust outlet 4 is provided at its top. Similarly, the cross-sectional area of the second suction duct 11 is designed to gradually decrease from bottom to top, and a second dust outlet 6 is provided at its top. The beneficial effect of this solution is that the tapered suction duct structure creates a Venturi effect at the top dust outlet, effectively accelerating the speed of the rising airflow, thereby significantly enhancing the system's suction capacity and efficiency for fine dust.

[0032] By adopting the above technical solution, the first dust removal duct 12 passes through the first rectangular cylinder 8, connects to the first dust removal space, and is ultimately connected to the negative pressure pipe 7. The second dust removal duct 13 passes through the second rectangular cylinder 10, connects to the second dust removal space, and is ultimately connected to the negative pressure pipe 7.

The beneficial effect of this solution is that the independently set dust removal ducts ensure that a sealed and efficient communication path is formed between each dust removal space and the negative pressure source, realizing independent control and stable delivery of negative pressure in the two dust removal sections.
[0033] Please refer to Figure 1 The dust removal assembly 2 also includes: a dust suction chamber, which is located below the first processing section and the second processing section, for sucking up the dust generated by the first processing section and the second processing section during processing; a filter screen, which is located at the top of the dust suction chamber; and a third dust removal duct 14, which is connected to the dust suction chamber and to the negative pressure pipe 7.
[0034] By adopting the above technical solution, the dust removal component 2 is further equipped with a dust suction chamber located below the first and second processing sections. A filter screen is installed at the top of the dust suction chamber, and it is connected to the negative pressure pipeline through the third dust removal duct 14. The beneficial effect of this solution is that the dust suction chamber can effectively suck up settled or scattered dust from directly below the processing area, the filter screen initially intercepts large particles or flocculent matter to prevent clogging of the pipeline, and the third dust removal duct 14 supplements the bottom suction path, forming a more comprehensive three-dimensional dust removal network together with the dust collection box above.
[0035] Please refer to Figure 2 The forming machine body 1 includes: a processing table 15, which is mounted on a mounting reference; a support 16, which is mounted on the processing table 15 and extends along the width direction of the processing table 15; a first dust removal section and a second dust removal section, which are respectively spaced apart on the support 16 along the width direction of the processing table 15; a slitting knife, which is mounted on the processing table 15; a lower chamfering knife, which is mounted on the processing table 15 and spaced apart from the slitting knife along the width direction of the processing table 15; and an upper chamfering knife, which is positioned above the lower chamfering knife and is mounted on the support 16 via a connecting plate; wherein the slitting knife forms a first processing section; and the upper and lower chamfering knives form a second processing section.
[0036] By adopting the above technical solution, the specific structure of the molding machine body 1 includes a processing table 15 mounted on a reference, a support 16 mounted on the processing table 15 and extending along its width direction, and a first dust removal unit and a second dust removal unit installed alternately on the support 16; a slitting knife is set on the processing table 15 as the first processing unit, and a lower chamfering knife and an upper chamfering knife set located above it and mounted on the support 16 through a connecting plate together constitute the second processing unit. The beneficial effect of this solution is that the dust removal unit is stably positioned directly above the processing area by the support 16, and its width-direction spacing precisely corresponds to the positions of the lower slitting knife (first processing unit) and the chamfering knife group (second processing unit), ensuring that each dust removal space can efficiently cover its corresponding dust generation source, achieving precise dust removal.
[0037] Working principle:
[0038] When the raw material is processed on the processing table 15 of the forming machine body 1, the slitting knife (first processing section) longitudinally cuts the material, generating fiber dust. At the same time, the second processing section, composed of the upper and lower chamfering knives, performs end face chamfering, generating particulate matter. At this time, the first dust collection box 3, located directly above the slitting knife, captures the cutting dust through the first dust inlet at its bottom. The dust initially settles in the first dust collection space enclosed by the first rectangular cylinder 8. Simultaneously, the second dust collection box 5, located directly above the chamfering knife group, draws in chamfering dust through the second dust inlet at its bottom, which remains in the second dust collection space formed by the second rectangular cylinder 10. The two dust-laden airflows are accelerated upwards through the first suction duct 9 and the second suction duct 11, which have gradually decreasing cross-sectional areas (forming a Venturi effect), and are finally discharged through the first dust outlet 4 and the second dust outlet 6 at the top. The negative pressure pipe 7 draws airflow from the dual dust collection boxes through the first dust collection duct 12 and the second dust collection duct 13 connected in parallel. The dust collection chamber set below the processing table 15 draws in settled dust from the bottom. After the flocculent material is intercepted by the top filter screen, it flows into the negative pressure pipe 7 through the third dust collection duct 14 and is then removed by an external fan and external dust filtration equipment.
