Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a dust removal system for a saw blade cutting machine. Background Technology

[0002] Currently, laser cutting machines are commonly used to cut saw blades. However, the saw blade cutting process generates metal dust, chips, and cutting waste. If these pollutants are not treated in time, they will accumulate inside the equipment, potentially causing jamming in the saw blade conversion mechanism and the moving parts of the cutting head, reducing the equipment's accuracy and lifespan. Existing dust removal systems generally suffer from limited dust collection range, crude waste disposal, and inconvenient maintenance, making it difficult to meet the high-efficiency and environmentally friendly production requirements of saw blade cutting machines. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and provide a dust removal system for a saw blade cutting machine.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a dust removal system for a saw blade cutting machine, comprising a chamber, a frame installed inside the chamber, a saw blade cutting mechanism mounted on the frame, a saw blade conversion mechanism on one side of the frame, and a dust extraction pipe slidably inserted into the frame via a key. The dust extraction pipe is cylindrical, and multiple arc-shaped dust extraction ports are evenly distributed around its circumference. The edges of the dust extraction ports are consistent with the curvature of the dust extraction pipe, and the dust extraction ports face the saw blade conversion mechanism. Below the saw blade conversion mechanism is a double-layer waste cart, the upper layer of which is a receiving box with a screen, and the lower layer is a dust collection bin. A downward-blowing fan is installed at the top of the interior of the chamber.

[0005] Furthermore, a concave clamp is fixedly installed on the side of the frame, and keying is provided at both ends and the middle of the clamp. A sliding groove that cooperates with the keying is opened on the outer side of the dust extraction pipe, and the dust extraction pipe is inserted into the clamp through the sliding groove.

[0006] Furthermore, the arc angle of the arc-shaped suction port is 130°-180°.

[0007] Furthermore, one end of the dust extraction pipe is closed, and the other end is connected to a vacuum cleaner outside the chamber via a connecting pipe.

[0008] Furthermore, the collection box is retractably installed on the upper layer of the double-layer waste cart to collect large-particle saw blade fragments, and both the collection box and the side of the double-layer waste cart are equipped with traction rods.

[0009] Furthermore, an arc-shaped metal grille is installed on the outside of each of the dust inlets to prevent saw blade debris from entering the dust extraction pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The dust extraction pipe is cylindrical with multiple evenly spaced arc-shaped dust extraction ports (arc angle 130°-180°) facing the saw blade switching mechanism. It can simultaneously capture smoke and dust from the upper side of the cutting area and debris falling during saw blade switching. Combined with the downward-blowing fan at the top of the chamber, it forms a three-dimensional airflow field of "suction + blowing", expanding the dust removal range and improving dust capture efficiency.

[0012] 2. The dust extraction pipe is installed by engaging the key and sliding groove of the concave clamp on the side of the frame. It can be directly inserted or pulled out from the side door of the hopper. Installation, disassembly and cleaning maintenance can be completed without tools, reducing the difficulty of equipment maintenance and downtime.

[0013] 3. In the double-layer waste cart structure, the upper layer is a collection box with a screen for collecting large pieces of saw blade fragments; the lower layer is a dust bin for collecting fine dust. The screen enables waste particle size classification, facilitating subsequent sorting, recycling, or processing and reducing manual sorting costs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0022] Combination Figures 1 to 5 The dust removal system of a saw blade cutting machine shown includes a hopper 1, a frame 2 inside the hopper 1, a saw blade cutting mechanism on the frame 2, a saw blade conversion mechanism 3 on one side of the frame 2, and a dust extraction pipe 4 slidably inserted into the frame 2 via a key. The dust extraction pipe 4 is cylindrical and has multiple arc-shaped dust extraction ports 41 evenly distributed around its circumference. The edges of the dust extraction ports 41 are consistent with the curvature of the dust extraction pipe 4, and the dust extraction ports 41 face the saw blade conversion mechanism 3. Below the saw blade conversion mechanism 3 is a double-layer waste cart 5. The upper layer of the double-layer waste cart 5 is a material collection box 51 with a screen, and the lower layer is a dust collection bin 52 for collecting dust. A downward-blowing fan 6 is installed at the top of the interior of the hopper 1.

[0023] like Figure 2-3 As shown, a concave clamping plate 7 is fixedly installed on the side of the frame 2. The clamping plate 7 has locking keys 71 at both ends and the middle section. The outer side of the dust extraction pipe 4 has a sliding groove 42 that cooperates with the locking key 71. The dust extraction pipe 4 is inserted into the clamping plate 7 through the sliding groove 42. When installing the dust extraction pipe 4, it can be inserted into the clamping plate 7 through the door on the side of the chamber 1. When disassembling, the connection with the vacuum cleaner 8 can be disconnected first, and then the dust extraction pipe 4 can be directly pulled out through the sliding groove 42 for cleaning, maintenance or replacement.

[0024] like Figure 1 and 4As shown, one end of the dust extraction pipe 4 is closed, and the other end is connected to the vacuum cleaner 8 on the outside of the chamber 1 through a connecting pipe; the arc-shaped dust extraction port 41 has an arc angle of 130°-180°. Thus, when the vacuum cleaner 8 is started, the dust extraction port 41 can not only suck up the smoke and dust generated when the laser cutting head cuts the saw blade from the side and above, but also suck up the debris and residue that fall from the saw blade conversion mechanism 3; in addition, in conjunction with the fan 6 blowing downwards from the top of the chamber 1, it can suck up the smoke and dust and residue around the saw blade conversion mechanism 3 at a large angle.

[0025] To prevent large pieces of saw blade remaining after cutting from being sucked into the dust extraction pipe 4 when the dust extraction port 41 is sucking up smoke and residue in the chamber 1, causing blockage in the pipe, an arc-shaped metal grille is installed on the outside of each dust extraction port 41 to prevent saw blade debris from entering the dust extraction pipe 4.

[0026] like Figure 5 As shown, the collection box 51 is detachably installed on the upper layer of the double-layer waste cart 5 to collect large-particle saw blade fragments. Both the collection box 51 and the double-layer waste cart 5 are equipped with traction rods on their sides.

[0027] Working Principle: When the saw blade cutting mechanism is working, the saw blade switching mechanism drives the saw blade to rotate or change position, and the dust and debris generated during the cutting process are diffused in all directions. The vacuum cleaner starts, and a negative pressure is created through the connecting pipe at the end of the suction pipe, causing air carrying dust to be sucked into the suction pipe from the suction port. Because the suction port faces the saw blade switching mechanism and has a large arc angle design, it can efficiently capture dust in the cutting area and near the switching mechanism, especially fine particles suspended in the air. The fan at the top of the bin blows downwards, blowing the dust floating above towards the suction port, which works in conjunction with the suction airflow of the vacuum cleaner to enhance the movement of dust towards the suction pipe and improve dust removal efficiency. Larger saw blade fragments that fall during cutting or switching fall directly to the upper collection box of the double-layer waste cart due to gravity and are intercepted and retained by the screen. Fine dust particles drawn in by the airflow are transported through the dust extraction pipe to a vacuum cleaner (or external dust removal equipment) for filtration. Dust particles not captured by the suction port are carried by the fan to a double-layer waste cart, where they fall through a screen into the lower dust bin, thus separating dust from larger particles. When cleaning the dust extraction pipe, first disconnect it from the vacuum cleaner, then pull the pipe horizontally out of the bin along the groove in the clamp. Remove any accumulated dust or blockages before reinstalling. The collection box and dust bin can be directly pulled out using the pull rod, empty the waste, and then reset to their original positions, completing the waste disposal process.

[0028] In this utility model, the saw blade conversion mechanism drives the central shaft to rotate via a conversion motor, which in turn drives the four positioning trays to rotate synchronously. The four positioning trays are divided into two groups when working. The two laser cutting heads in the saw blade cutting mechanism cooperate with the two positioning trays for saw blade cutting. This is existing technology. Furthermore, this utility model mainly describes the dust removal system during the processing, so it will not be elaborated on in detail.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
