Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a dust collection structure for a dust collector used in laser cutting. Background Technology

[0002] Laser cutting equipment generates a large amount of smoke and dust when cutting metal materials. Therefore, a dust collector is needed to collect and treat the smoke and dust generated by laser cutting. Existing laser cutting dust collectors mainly use impellers or fans to create negative pressure inside the dust collector box. The smoke, dust and cutting debris generated by laser cutting are sucked into the dust collector box through the air inlet and filtered by the filter cartridge inside the dust collector box to remove the debris and dust, thereby purifying the air. Finally, the filtered dust and debris are discharged through the drain outlet.

[0003] In the existing technology, a collection device is usually installed at the sewage outlet of the dust collector to collect the discharged dust and debris and other pollutants for centralized transfer and treatment. The collection device is usually a collection bin, which is mostly fastened to the sewage outlet of the dust collector with bolts. However, the bolt fastening method requires the use of tools such as wrenches to tighten, which is time-consuming, labor-intensive and not convenient or fast. Utility Model Content

[0004] The purpose of this invention is to provide a dust collection structure for a dust collector used in laser cutting, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A dust collection structure for a laser cutting dust collector includes a dust collector body with a drain port at the bottom and a sludge collection hopper detachably installed below the drain port. Two retaining strips are fixed to both sides of the bottom of the drain port, extending along the width of the dust collector body. A rectangular mounting frame is fixed to the top of the sludge collection hopper, and mounting slots adapted to the retaining strips are provided on both sides of the mounting frame. The drain port can be correspondingly fitted into the mounting slots. The retaining strips have a T-shaped cross-section, and the mounting slots are T-shaped grooves that match the retaining strips.

[0007] As can be seen, by using two clips to slide and engage with the corresponding slots, the sewage outlet and the sludge collection hopper can be assembled. The cross-sections of the clips and the slots are T-shaped and match each other, which has a limiting effect in the vertical direction and effectively prevents the sludge collection hopper from falling downwards. The installation of the sludge collection hopper is achieved by sliding and engaging the clips and the slots, making the assembly and disassembly of the sludge collection hopper convenient and quick.

[0008] Furthermore, a mounting block is fixed to the side of the sewage outlet. The mounting block has a vertically penetrating guide hole, and a pin is slidably inserted into the guide hole. The upper surface of the mounting frame has a socket, and the pin can be correspondingly inserted into the socket to lock the mounting frame in place.

[0009] Furthermore, a limit baffle is fixed to one side of the bottom of the sewage outlet. When the mounting frame and the limit baffle are in contact and fit together, the position of the pin rod is aligned with the position of the insertion hole.

[0010] Furthermore, L-shaped plates with an L-shaped cross section are fixed on both sides of the sludge collection hopper, and casters are installed on both sides below the two L-shaped plates, with at least two casters having a braking effect.

[0011] Furthermore, each caster wheel has a vertically extending fastening screw fixed to its top, and each fastening screw is detachably threaded into a screw hole on the L-shaped plate.

[0012] Furthermore, handles are installed on both sides of the sludge collection hopper, and both handles are U-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model utilizes two locking strips to slide and engage with corresponding slots to assemble the drain outlet and the sludge collection hopper. The cross-sections of the locking strips and the slots are T-shaped and match each other, which provides a limiting effect in the vertical direction and effectively prevents the sludge collection hopper from falling downwards. The installation of the sludge collection hopper is achieved by sliding and engaging the locking strips and the slots, making the assembly and disassembly of the sludge collection hopper convenient and quick.

[0015] 2. This utility model uses a pin rod inserted into the insertion hole to limit the horizontal movement of the sludge collection hopper, preventing it from shifting horizontally and ensuring the sludge collection hopper is firmly installed. In addition, the pin rod is vertically set and can be stably inserted into the insertion hole by gravity, making it less likely to come out, and further improving the convenience of disassembly and assembly.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-6The present invention provides a dust collection structure for a dust collector used in laser cutting, comprising a dust collector body 1 with a drain port 11 at the bottom and a sludge collection hopper 2 detachably installed below the drain port 11. Two retaining strips 111 are fixed to the bottom sides of the drain port 11, both extending along the width of the dust collector body 1. A rectangular mounting frame 3 is fixed to the top of the sludge collection hopper 2. The mounting frame 3 has mounting grooves 31 on both sides that are adapted to the retaining strips 111. The drain port 11 can be correspondingly fitted into the mounting grooves 31. The retaining strips 111 have a T-shaped cross-section, and the mounting grooves 31 are T-shaped grooves that match the retaining strips 111.

[0027] During installation, the two locking strips 111 are aligned with the two locking slots 31 and slid in place. The two locking strips 111 are slid in place into the corresponding locking slots 31 to assemble the drain outlet 11 and the sludge collection hopper 2. The cross-sections of the locking strips 111 and the locking slots 31 are T-shaped and match each other, which provides a limiting effect in the vertical direction and effectively prevents the sludge collection hopper 2 from falling downwards. After assembly, dust and debris discharged from the drain outlet 11 inside the dust collector body 1 fall into the sludge collection hopper 2 for collection. When the sludge collection hopper 2 is full, it can be slid to one side to separate the locking strips 111 and the locking slots 31, allowing the sludge collection hopper 2 to be removed for easy transfer and subsequent treatment of the dirt inside. The installation of the sludge collection hopper 2 is achieved by sliding the locking strips 111 and the locking slots 31, making the installation and removal of the sludge collection hopper 2 convenient and quick.

[0028] Specifically, a mounting block 4 is fixed to the side of the drain outlet 11. The mounting block 4 has a vertically penetrating guide hole 41. A pin rod 42 is slidably inserted into the guide hole 41. The upper surface of the mounting frame 3 has a socket 301. The pin rod 42 can be correspondingly inserted into the socket 301 to achieve the holding of the mounting frame 3. By inserting the pin rod 42 into the socket 301, it has a limiting effect in the horizontal direction, which can prevent the sludge hopper 2 from shifting in the horizontal direction, further ensuring the firmness of the installation of the sludge hopper 2. In addition, the pin rod 42 is set vertically, and can be stably inserted into the socket 301 by gravity, which is not easy to fall out, and further improves the convenience of disassembly and assembly.

[0029] Specifically, a limiting baffle 12 is fixed to one side of the bottom of the drain outlet 11. When the mounting frame 3 and the limiting baffle 12 are in contact and fit together, the position of the pin 42 is aligned with the position of the insertion hole 301. When the mounting frame 3 is installed at the bottom of the drain outlet 11, the limiting baffle 12 is in contact and fit together with the side of the mounting frame 3 to achieve a positioning effect, so that the pin 42 is aligned with the position of the insertion hole 301, which makes it easy for the pin 42 to be inserted into the insertion hole 301 smoothly and quickly. At the same time, the limiting baffle 12 also prevents the mounting frame 3 from moving excessively, achieving two goals at once.

[0030] Specifically, L-shaped plates 21 with an L-shaped cross section are fixed on both sides of the sludge collection hopper 2. Universal wheels 22 are installed on both sides below the two L-shaped plates 21. By setting universal wheels 22, it is convenient to transfer the collected dust, debris and other dirt in the later stage. At least two universal wheels 22 have a braking effect, which helps to keep the sludge collection hopper 2 in a stationary state.

[0031] Specifically, each caster wheel 22 has a vertically extending fastening screw 221 fixed to its top. Each fastening screw 221 is detachably threaded into a screw hole on the L-shaped plate 21. By using the installation method of threading the fastening screw 221 into the screw hole on the L-shaped plate 21, the caster wheel 22 can be easily replaced when it is severely worn.

[0032] Specifically, handles 23 are installed on both sides of the sludge collection hopper 2. Both handles 23 are U-shaped. By setting the U-shaped handles 23 on the side of the sludge collection hopper 2, it is convenient to move the sludge collection hopper 2.

[0033] 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.
