Description

Technical Field

[0001] The utility model relates to the field of dustproof net processing, in particular to a shearing machine for producing and processing dustproof nets at outdoor construction sites. Background Art

[0002] The construction site dust net, also known as the soil cover net or sunshade soil cover net, has the main function of preventing the soil, dust and other debris on the construction site from being blown away by the wind, thereby reducing air pollution and protecting the environment. In addition, it also has multiple functions such as shading and cooling, moisturizing and preventing rainstorms, resisting wind and reducing the spread of pests.

[0003] The traditional dust-proof net production and processing shearing machine includes a workbench, a bracket is installed on the top of the workbench, and a first motor is installed on the outer wall of the bracket; when the dust-proof net main body needs to be sheared, the position of the dust-proof net main body is fixed by using the positioning plates on both sides, and the top of the dust-proof net main body is limited by using the limiting plates, and when the dust-proof net main body is cut, the position of the dust-proof net main body can be moved by using the conveyor belt, which solves the problem that the general dust-proof net cutting device has a simple structure and its position cannot be fixed when the dust-proof net is cut, resulting in the cutting position is not accurate enough, and the dust-proof net will be wasted, which leads to the problem of waste of raw materials during the processing of the dust-proof net, and improves the efficiency of the cutting device for the production and processing of the dust-proof net.

[0004] In the prior art, the dustproof net is fixed and limited by a positioning plate and a limit plate, and then a cutting device is used to cut the dustproof net. However, the dustproof net is transported and cut in large rolls. After this section is fixed and cut, the staff needs to take away the cut dustproof net, and then drag the dustproof net to be cut to move and lay it on the workbench, and then use the fixed limit device to fix the dustproof net. After fixing it, the shearing device is used to cut the dustproof net again, and the work is performed reciprocatingly. This will force the staff to continue to operate next to the machine and cannot extricate themselves, resulting in an increase in the staff's workload. Utility Model Content

[0005] The purpose of the utility model is to provide a shearing machine for producing and processing dustproof nets at outdoor construction sites to solve the following technical problems:

[0015] Beneficial effects of the utility model:

[0016] (1) The dust screen is placed on the placement plate on the workbench, and then the driving assembly is used to drive the working block to move. The movement of the working block drives the fixed block in the working block to move toward the placement plate. The fixed block is lifted upward by cooperating with the limit block on the placement plate and the lifting block on the fixed block. When the lifting block slides to the range of the limit rod, the opening on the lifting block cannot be engaged with the limit rod, so the lifting block will not be subjected to an upward force. At this time, the second spring releases the spring stress to squeeze the fixed block downward, so that the fixed block presses the dust screen on the placement plate. The driving assembly then drives the working block and the fixed block to move in the direction they came from, and pulls the dust screen to move together, so that the dust screen is laid on the workbench. This avoids the need for workers to continue standing next to the shearing machine to pull the dust screen, freeing the workers to do other work and only need to occasionally stare at the machine.

[0025] See also Figure 1-Figure 5 As shown, the utility model is a shearing machine for producing and processing dust-proof nets at outdoor construction sites, comprising a workbench 1; a shearing assembly is arranged on the workbench 1; the shearing assembly comprises a shearing knife 14; a driving assembly is arranged on the workbench 1; the driving assembly comprises a driving block 23; a working block 18 is fixedly connected to the top of the driving block 23; a movable column 19 is slidably connected to the working block 18; two movable columns 19 are provided, and are symmetrically arranged on the working block 18; a fixed block 20 is fixedly connected to the bottom of the movable column 19; a second spring 22 is sleeved on the movable column 19 between the fixed block 20 and the working block 18; a lifting block 21 is fixedly connected to the top of the fixed block 20; a support block 6 is fixedly connected to one end of the workbench 1; a placement plate 5 is fixedly connected to the top of the support block 6; a limiting rod 11 is fixedly connected to the top of the placement plate 5; an end of the limiting rod 11 away from the placement plate 5 is fixedly connected to the limiting block 12;

[0026] By placing the dust screen on the placement plate 5 on the workbench 1, and then using the driving component to drive the working block 18 to move, the movement of the working block 18 drives the fixed block 20 in the working block 18 to move toward the placement plate 5, and the fixed block 20 is lifted upward by cooperating with the limit block 12 on the placement plate 5 and the lifting block 21 on the fixed block 20. The fixed block 20 will carry the movable column 19 upward and compress the second spring 22.

While lifting, the driving component still drives the working block 18 and the fixed block 20 to move toward the side of the placement plate 5. When the lifting block 21 slides out of the range of the limit block 12, because the lifting block 21 is provided with an opening, when the lifting block 21 slides to the range area of ​​the limit rod 11 The opening on the lifting block 21 cannot be engaged with the limit rod 11, so the lifting block 21 will not be subjected to an upward force. At this time, the second spring 22 releases the spring stress to squeeze the fixed block 20 downward, so that the fixed block 20 presses the dustproof net on the placement plate 5. The driving component then drives the working block 18 and the fixed block 20 to move in the direction they came from, and pulls the dustproof net to move together, so that the dustproof net is laid on the workbench 1. After laying, the shearing component is used to cut the dustproof net. After cutting, the dustproof net is laid on the workbench 1 through the same operation. This avoids the staff from standing next to the shearing machine to pull the dustproof net continuously, and can free the staff to do other work and only need to stare at the machine occasionally.
