Description

Technical Field

[0001] This utility model relates to the technical field of multifilament mesh cutting, and in particular to a fixed-length cutting device for multifilament mesh production. Background Technology

[0002] In the production of multi-wire mesh, the fixed-length cutting device is a key piece of equipment to ensure product quality and production efficiency. During the fixed-length cutting process, some errors may occur, and the excess part of the multi-wire mesh needs to be trimmed manually. However, existing fixed-length cutting methods all use sheet metal shears. However, when cutting long multi-wire mesh, the sheet metal shears are too close to the operator's hand, which can cause injury to the operator's hand. Furthermore, the cutting accuracy cannot be guaranteed when using sheet metal shears. To address the above problems, this application provides a fixed-length cutting device for multi-wire mesh production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fixed-length cutting device for multi-wire mesh production, which solves the technical problem of insufficient precision in the cutting process and achieves the goal of improving the cutting accuracy of multi-wire mesh.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fixed-length cutting device for multi-wire mesh production, comprising a support box as a support base, wherein the support box is provided with an isolation protection mechanism for protecting the operator's hands, and the support box is provided with an orientation cutting mechanism for calibrating the cutting accuracy. The directional cutting mechanism includes a downward flipping rod rotatably connected to the inside of the support box. A connecting plate is fixedly connected to the connection part between the downward flipping rod and the inside of the support box. An extension rod extending to the outside of the support box is fixedly connected to the end of the connecting plate. A return spring is connected to the outside of the extension rod. A cutting blade is rotatably connected to the lower inside of the support box via a rotating rod. A transition plate is fixedly connected to the top of the cutting blade. An adaptation groove is opened in the middle of the transition plate. The lower side of the connecting plate is slidably connected to the inside of the adaptation groove via a sliding rod.

[0005] Preferably, one end of the return spring is connected to the extension rod, and the other end of the return spring is connected to the outside of the support box.

[0006] Preferably, the isolation and protection mechanism includes an extended cutting box fixedly connected to one end of the support box. Side gaskets are fixedly connected to both ends of the outer side of the support box and the extended cutting box. A limit handle is fixedly connected to the top of the extended cutting box. A flip groove is opened on one side of the top of the support box. A limit cutting scissor seat is fixedly connected to one side of the inner side of the support box and the extended cutting box.

[0007] Preferably, the limiting cutter holder is in contact with the cutter.

[0008] Preferably, the downward flipping rod is located inside the flipping groove.

[0009] Preferably, the side gasket and the bottom of the limiting cutter seat are on the same horizontal plane.

[0010] By means of the above technical solution, this utility model provides a fixed-length cutting device for multi-wire mesh production, which has at least the following beneficial effects: 1. Due to the directional cutting mechanism, this utility model can accurately cut multi-wire mesh. By placing a support under the multi-wire mesh to be cut, the cutting blades are then pierced through the multi-wire mesh during the subsequent cutting process. The side of the cutting blades is then attached to the side of the supporting pad before cutting, which ensures the accuracy of the cutting.

[0011] 2. Due to the isolation and protection mechanism, this utility model can protect the operator's hands and prevent the operator's hands from being cut by the edges of the cut multi-wire mesh during the cutting process. At the same time, since the operator does not have to be accidentally cut, the cutting efficiency can be accelerated. Attached Figure Description

[0015] 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.

[0016] Example 1 Existing fixed-length cutting methods all use sheet metal shears. However, when cutting long multi-wire mesh, the close proximity of the mesh to the operator's hand can cause injury, and the cutting precision cannot be guaranteed. Please refer to... Figures 1-4 This embodiment provides a fixed-length cutting device for multifilament mesh production, solving the technical problem of insufficient cutting accuracy. The device includes a support box 1 as a supporting base, an isolation protection mechanism 2 for protecting the operator's hands, and an directional cutting mechanism 3 for calibrating cutting accuracy inside the support box 1. The multifilament mesh is cut using the directional cutting mechanism 3, while the isolation protection mechanism 2 protects the operator's hands from injury.

[0017] During the cutting of multi-wire mesh, some excess parts are inevitable. These excess parts need to be cut manually. Manual cutting and finishing require the use of sheet metal cutters. However, the cutting process can cause injury to the operator's hands and cannot guarantee the cutting accuracy. In order to solve this problem, a directional cutting mechanism 3 is proposed. The directional cutting mechanism 3 includes a downward flipping rod 31 rotatably connected to the inside of the support box 1. A connecting plate 32 is fixedly connected to the connection part between the downward flipping rod 31 and the inside of the support box 1. An extension rod 33 extending to the outside of the support box 1 is fixedly connected to the end of the connecting plate 32. A return spring 34 is connected to the outside of the extension rod 33. A cutting blade 37 is rotatably connected to the lower inside of the support box 1 via a rotating rod 38. A transition plate 35 is fixedly connected to the top of the cutting blade 37. An adaptation groove 36 is opened in the middle of the transition plate 35. The lower side of the connecting plate 32 is slidably connected to the inside of the adaptation groove 36 via a sliding rod. One end of the return spring 34 is connected to the extension rod 33, and the other end of the return spring 34 is connected to the outside of the support box 1.

[0018] During the cutting stage, the operator presses down the flip-down lever 31, which causes the connecting plate 32 connected to it to rotate. The connecting plate 32 then drives the adapter plate 35 to rotate via a slide rod on one side. The adapter plate 35 then drives the cutting shears 37 connected to it to rotate. During this process, the return spring 34 connected to the extension rod 33 at one end of the connecting plate 32 will reset the connecting plate 32, thereby resetting the flip-down lever 31. This cycle is repeated to cut the multi-wire mesh using the cutting shears 37.

[0019] Example 2 Based on Example 1, which solved the technical problem of insufficient precision in the cutting process, Example 1 still had the problem of easily injuring the operator's hands. Combined with... Figures 1-4 As shown, the specific implementation process is as follows: In order to protect the operator's hands and prevent injury during the cutting process, an isolation protection mechanism 2 is proposed. The isolation protection mechanism 2 includes an extended cutting box 21 fixedly connected to one end of the support box 1. Side pads 22 are fixedly connected to both ends of the support box 1 and the extended cutting box 21. A limit handle 23 is fixedly connected to the top of the extended cutting box 21. A flip groove 24 is opened on one side of the top of the support box 1. A limit cutting scissor seat 25 is fixedly connected to one side of the inside of the support box 1 and the extended cutting box 21. The limit cutting scissor seat 25 is in contact with the cutting scissors 37. The downward flipping rod 31 is located inside the flip groove 24. The bottom ends of the side pads 22 and the limit cutting scissor seat 25 are on the same horizontal plane.

[0020] During the cutting process, the operator holds the limit handle 23 with their fingers and the pressure flipping lever 31 with their hands, which makes the operation process simpler and faster. The side pad 22 can ensure that the cutting device is in a horizontal state, while the extended cutting box 21 can protect the operator's hands from contacting the multi-wire mesh and avoid injury to the operator.
