Description

Technical Field

[0001] The utility model relates to the technical field of metal wire mesh processing equipment, in particular to a metal wire mesh cutting device. Background Art

[0002] Wire mesh is the collective name for metal and wire mesh. Wire mainly refers to wire made of metal or non-metal; mesh is made of wire and is woven into meshes of different shapes, densities and specifications according to demand. After the production of the wire mesh is completed, it needs to be cut according to the required size for subsequent use and transportation. There are two existing cutting methods. One is that workers use shears to manually cut the wire mesh, which will result in an uneven cutting surface and low cutting efficiency. The other is to use a cutting machine to cut the wire mesh. During the cutting process, workers are required to press and move the wire mesh to change the cutting position, which will increase the workers' fatigue and have low cutting efficiency.

[0003] The utility model patent with application number 201921954717.4 discloses a new type of wire mesh cutting device. The new type of wire mesh cutting device drives the wire mesh forward through a pressure wheel and drives the cutter up and down through a crankshaft connecting rod, making the wire mesh cutting convenient and quick, greatly reducing the labor input, improving the efficiency of wire mesh cutting, and also reducing the cost of wire mesh cutting and avoiding unnecessary waste.

[0004] Although the above utility model patent drives the wire mesh forward by a pressure wheel, there is no need to manually move the wire mesh to change the cutting position, thereby improving the cutting efficiency. However, during the process of the cutter cutting the wire mesh, the two sides of the cut mouth of the wire mesh are not pressed and fixed. The wire mesh may shift left and right during the transportation process, which will affect the cutting effect of the cutter on the wire mesh, making the cut mouth uneven and affecting the cutting quality of the wire mesh.

[0005] Therefore, it is necessary to develop a metal wire mesh cutting device to address the above defects. Utility Model Content

[0027] With reference to the accompanying drawings, Figure 1 It is a schematic diagram of the front cross-sectional structure of the metal wire mesh cutting device of the utility model; Figure 2 It is a side view of the metal mesh cutting device of the utility model; Figure 3 It is a top view of the metal wire mesh cutting device of the utility model; Figure 4 for Figure 1 A partial enlarged view of part A.

[0028] In a specific embodiment, Figure 1 to Figure 4As shown, a wire mesh cutting device comprises a workbench 1, a cutting table 2 and a side plate 3, wherein the cutting table 2 is horizontally arranged on the top surface of the workbench 1, and the side plates 3 are in two pieces and are respectively fixed vertically on the top surfaces of both sides of the workbench 1, and further comprises a conveying mechanism 4, a cutting mechanism 5 and a pressing mechanism 6; the cutting mechanism 5 comprises a driving unit 501, a second mounting plate 502 and a cutter 503, wherein the cutter 503 is vertically fixedly mounted on the bottom surface of the second mounting plate 502 with the blade facing downward, the driving unit 501 drives the second mounting plate 502 to reciprocate up and down, and the cutter 503 cuts the wire mesh on the workbench 1; the pressing mechanism 6 comprises a plurality of elastic pressing components, which are fixedly connected to the bottom surface of the second mounting plate 502 and can press the cutter 503 before it contacts the wire mesh, and the plurality of elastic pressing components are divided into two groups and are respectively arranged on the front and rear sides of the cutter 503; the conveying mechanism 4 is arranged on the side plate 3 and can drive the wire mesh to move to the cutting mechanism 5 for cutting.

[0029] By arranging a clamping mechanism 6 on both sides of the cutter 503, during the wire mesh cutting process, when the cutter 503 moves downward to cut the wire mesh on the cutting table 2, the clamping mechanism 6 simultaneously clamps and fixes both sides of the wire mesh to prevent the wire mesh from moving when being cut, thereby affecting the cutting quality of the wire mesh.

[0030] In a specific embodiment, Figure 4 As shown, the elastic clamping assembly includes a connecting rod 601, a sleeve 602 and an elastic member 603. The top end of the connecting rod 601 is fixedly connected to the bottom surface of the second mounting plate 502, and the sleeve 602 is slidably sleeved on the bottom end of the connecting rod 601. The bottom surface of the sleeve 602 contacts the metal wire mesh; the elastic member 603 is arranged in the sleeve 602 and is clamped between the bottom surface of the sleeve 602 and the bottom end surface of the connecting rod 601.

[0031] By arranging an elastic member 603 between the sleeve 602 of the clamping mechanism 6 and the connecting rod 601, the impact force on the metal wire mesh when the clamping mechanism 6 moves downward synchronously with the cutter 503 can be buffered, thereby avoiding damage to the metal wire mesh by the clamping mechanism 6.

[0032] In a specific embodiment, the driving unit 501 specifically adopts an electric cylinder, a first mounting plate 506 is arranged across the middle position of the top surface of the side plate 3, three synchronously running electric cylinders are fixedly connected to the middle position of the bottom surface of the first mounting plate 506, and the telescopic end of the electric cylinder is fixedly connected to the top surface of the second mounting plate 502.

[0033] It should be noted that the three electric cylinders move synchronously through the control system and perform telescopic movements at the same time. In other embodiments, the number of electric cylinders can be set to multiple, and the drive unit 501 can be replaced by hydraulic cylinders or pneumatic cylinders and other equipment or components, as long as it can drive the cutter 503 on the second mounting plate 502 to reciprocate up and down to cut the wire mesh on the workbench 1.

[0034] Specifically, the inner side walls of the side panels 3 are respectively provided with guide rails 504 in a vertically symmetrical manner, and sliders 505 are fixedly installed on both side surfaces of the second mounting plate 502 close to the side panels 3 , and the sliders 505 are slidably connected to the guide rails 504 .

[0035] By providing the guide rail 504 and the slider 505 , the friction between the second mounting plate 502 and the side plate 3 when the second mounting plate 502 moves up and down can be reduced, thereby improving the cutting stability of the metal wire mesh by the cutter 503 .

[0036] In a specific embodiment, the conveying mechanism 4 includes a conveying roller 402, an output roller 403 and a motor 404. The conveying roller 402 and the output roller 403 are respectively arranged horizontally and parallel on both sides of the cutter 503, and the two ends of the conveying roller 402 and the output roller 403 are respectively rotatably connected to the inner wall of the side plate 3; the motor 404 is fixedly installed on the outer wall of the side plate 3 and the output end shaft passes through the side plate 3 and is fixedly connected to the top of one side of the conveying roller 402, and the first transmission wheel 405 is correspondingly fixedly connected to the top of the output roller 403 and the output end shaft of the motor 404, and the first transmission wheels 405 are connected by a transmission belt 406.

[0037] The conveying roller 402 is driven to rotate by the rotation of the motor 404, and the first transmission wheel 405 on the rotating shaft of the motor 404 rotates synchronously at the same time, and the first transmission wheel 405 on the output roller 403 is driven to rotate synchronously through the transmission belt 406, and the output roller 403 is further driven to rotate, so that the conveying roller 402 and the output roller 403 rotate synchronously. The end of the metal wire mesh to be cut is placed under the conveying roller 402, and the rotation time of the motor 404 is controlled according to the length of the metal wire mesh to be cut, so that the conveying roller 402 drives the position of the metal wire mesh to be cut to move to the bottom of the cutting mechanism, and then the output roller 403 rotates synchronously to drive the metal wire mesh after cutting to continue to move forward for collection, so as to avoid blocking the cutting of the uncut metal wire mesh, and then cut other positions of the metal wire mesh.

[0038] Specifically, support frames 407 are vertically fixed on both sides of one end of the workbench 1 close to the conveying roller 402, a U-shaped groove 408 is opened on the top of the support frame 407, and a feed roller 401 is straddled on the U-shaped groove 408; a second transmission wheel 409 is fixedly connected to the top of the feed roller 401 close to the motor 404, and a second transmission wheel 409 is fixedly connected to the corresponding rotating shaft at the output end of the motor 404, and the second transmission wheels 409 are connected by a transmission belt 406.

[0039] By providing the feed roller 401, it is convenient to sleeve the wire mesh roll onto the outer surface of the feed roller 401, and the second rotating wheel 409 is driven to rotate by the motor 404, and the feed roller 401 is driven to rotate by the transmission belt 406, so as to facilitate the feeding of the wire mesh on the wire mesh roll to the cutting table 2.

[0040] Specifically, the height of the conveying roller 402 and the output roller 403 from the cutting table 2 is the same as the thickness of the metal wire mesh, and the outer periphery of the conveying roller 402 and the output roller 403 is coated with an anti-skid rubber pad 410 .

[0041] The outer periphery of the conveying roller 402 and the output roller 403 is covered with an anti-skid rubber pad 410, which can increase the friction between the conveying roller 402 and the output roller 403 and the metal wire mesh, and ensure the stability of driving the metal wire mesh to move.

[0042] In a specific implementation, a rubber pad 604 is fixedly connected to the bottom surface of the sleeve 602 .

[0043] The rubber pad 604 is arranged on the bottom surface of the sleeve 602, which can reduce the damage to the metal wire mesh when the sleeve 602 is directly pressed on the metal wire mesh, and at the same time increase the friction with the metal wire mesh, thereby improving the pressing and fixing effect of the metal wire mesh.

[0044] The working principle of the utility model is as follows: when in use, the wire mesh reel is sleeved and fixed on the feed roller 401, and then the outer end of the wire mesh is inserted under the conveying roller 402, and the motor 404 is started. The length signal of the wire mesh to be cut is collected according to the limit switch on the equipment and transmitted to the controller of the electric control box. The controller controls the start and stop of the motor 404. The conveying roller 402 drives the wire mesh to move to the position where it needs to be cut to the bottom of the cutting mechanism, and then the motor 404 stops, the electric cylinder is started, and the three electric cylinders synchronously drive the cutter 503 on the second mounting plate 502 to move downward to cut the wire mesh on the workbench 1. At the same time, the clamping mechanism 6 on both sides of the cutter 503 moves downward with the second mounting plate 502, and clamps and fixes the wire mesh on both sides of the cutter to prevent the wire mesh from being dislocated when cutting, and can prevent the wire mesh clamping knife from moving up when returning the knife, which is not convenient for continuing to transport backward. After the cutting is completed, the motor 404 is started again, and the output roller 403 rotates to drive the cut wire mesh to continue to move forward for collection, and the conveying roller 402 continues to drive the wire mesh on the wire mesh reel to move to the bottom of the cutting mechanism for the next cutting.

[0045] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0046] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
