Description

Technical Field

[0001] The utility model relates to the technical field of plate processing equipment accessories, in particular to a dust collecting hood with a limiting block. Background Art

[0002] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly increasing, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc. However, during the operation of the cutting machine, a large amount of debris and sparks will be generated at the cutting blade. If they are not collected, it will affect environmental hygiene and health. At the same time, the existing cutting machine has a slow fixing speed, which affects the cutting efficiency.

[0003] At present, the industry has set a dust hood above the saw blade of the cutting equipment. Although the dust hood solves the problem of cutting debris splashing, the dust hood will come into contact with the sharp parts of the saw blade such as the teeth during use, causing the dust hood to collapse and even pose a potential threat of injury. In addition, most existing dust hoods use a fixed installation structure, which makes it impossible to adjust the dust hood when facing different specifications of plates. It needs to be disassembled and adjusted as a whole, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model provides a dust collecting hood with a limiting block to solve the problems in the prior art that the dust collecting hood is easily in contact with a cutting saw during cutting, resulting in damage to the hood body, and the dust collecting hood is fixedly installed and cannot be adjusted.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A dust collecting hood with a limiting block consists of a hood body and a bracket. An inner inclined surface is arranged at the feeding end of the hood body, a slot is arranged at the rear end of the hood body, an adjusting slot is arranged at the upper part of the bracket, a limiting hole is arranged in the adjusting slot, the upper part of the bracket extends into the slot of the hood body, a bolt passes through the slot of the hood body and the adjusting slot of the bracket, and a limiting block is arranged on both sides of the inner side of the movable slot of the saw blade at the bottom of the hood body.

[0007] Anti-skid areas are arranged on both sides of the front end of the cover body to improve the anti-skid property, so that when personnel have to manually adjust the dust collecting cover during operation, they can hold it firmly and it is not easy to fall out of their hands, thus protecting the safety of the operator.

[0008] The utility model arranges limit blocks on both sides of the inner side of the movable groove of the saw blade of the cover body, so that when the dust cover is in use, the dust cover will not come into contact with the sharp parts such as the teeth of the saw blade due to the restriction of the limit blocks, thereby avoiding the dust cover from collapsing during use and even the potential threat of injury.

[0009] The inner inclined surface design of the feed end of the cover body of the utility model facilitates the advancement of the plate under the cover body.

[0010] The bracket of the utility model is provided with a limiting hole, so that when cutting a substrate such as a thick plate, if the dust hood is inconvenient to use, the dust hood can be lifted up, and the mounting screws are pushed into the limiting holes. The dust hood will be suspended and fixed under the structural limitation, eliminating the trouble of disassembling and assembling the dust hood back and forth, making it more convenient to use and saving time. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0012] Figure 1 It is a structural schematic diagram of the utility model;

[0013] Figure 2 It is a bottom view schematic diagram of the utility model;

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a dust hood with limiting blocks is composed of a hood body 1 and a bracket 2. An inner bevel 3 is provided at the feed end of the hood body 1, a slot 4 is provided at the rear end of the hood body 1, the bracket is fixed on the cutting machine table through the mounting hole at the bottom, an adjustment slot 8 is provided at the upper part of the bracket, a limiting hole 9 is provided in the adjustment slot 8, the upper part of the bracket 2 extends into the slot 4 of the hood body 1, the bolt passes through the slot 4 of the hood body 1 and the adjustment slot 8 of the bracket 2, and a limiting block 5 is provided on both sides of the inner side of the movable notch of the saw blade at the bottom of the hood body 1. Anti-slip areas 7 are provided on both sides of the front end of the hood body 1 to improve the anti-slip property, so that when the personnel have to manually adjust the dust hood during operation, they can hold it firmly and it is not easy to slip out, thereby protecting the safety of the operator.

[0017] The utility model arranges limit blocks on both sides of the inner side of the movable groove of the saw blade of the cover body, so that when the dust cover is in use, the dust cover will not come into contact with the sharp parts such as the teeth of the saw blade due to the restriction of the limit blocks, thereby avoiding the dust cover from collapsing during use and even the potential threat of injury.

[0018] The inner inclined surface design of the feed end of the cover body of the utility model facilitates the advancement of the plate under the cover body.

[0019] The bracket of the utility model is provided with a limiting hole, so that when cutting a substrate such as a thick plate, if the dust hood is inconvenient to use, the dust hood can be lifted up, and the mounting screws are pushed into the limiting holes. The dust hood will be suspended and fixed under the structural limitation, eliminating the trouble of disassembling and assembling the dust hood back and forth, making it more convenient to use and saving time.
