According to the production process of wire mesh, it can be divided into weaving type, spot welding type, cutting and pulling type, stamping type, etc. Among them, the spot welding production process is the most common. Before spot welding, the iron wires should be arranged into a mesh and distributed in the wire frame. After spot welding, the excess ends of the iron wires that extend beyond the wire frame should be removed. The original process design is to grind off the excess ends of the iron wires through grinding, but this method is time-consuming and labor-intensive, and seriously reduces production efficiency.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] See attached Figure 1-4A wire rack head cutting mechanism includes a driving device and a cutting head 1. The driving device is connected to an eccentric wheel 7 through a driving shaft 6 and drives the eccentric wheel 7 to rotate with the driving shaft 6 as the axis. The eccentric wheel 7 is hinged with a slider 8. The slider 8 is slidably set in a liftable slide rail 9. The cutting head 1 is fixedly set on the slide rail 9. The rotation of the eccentric wheel 7 drives the slider 8 to move back and forth in the slide rail 9, thereby driving the slide rail 9 to move up and down. The cutting head 1 moves up and down with the slide rail 9 to cut. The driving device includes a motor 2, a driving wheel 3, a driven wheel 4 and a transmission belt 5. The output end of the motor 2 drives the driving wheel 3 to rotate. The driving wheel 3 and the driven wheel 4 are connected through the transmission belt 5. The driven wheel 4 is connected to the driving shaft 6 and drives the driving shaft 6 to rotate.

[0021] Based on the above technical solution, the cutting head mechanism of the utility model realizes the rapid lifting and lowering of the cutting head 1 through the driving device and the eccentric wheel 7. Therefore, during use, there is no need to align the head 1 with the wire end for cutting. It is only necessary to move a row of wire ends to be cut at a uniform speed and place them under the cutting head to complete the cutting in sequence.

[0022] Furthermore, the eccentric wheel 7 is hinged to the slider 8 via a pin.

[0023] Furthermore, one end of the drive shaft 6 is connected to the driven wheel key, and the other end of the drive shaft is connected to the eccentric wheel key.

[0024] Furthermore, the diameter of the driven wheel 4 is greater than the diameter of the driving wheel 3. The driven wheel 4 is a solid wheel, which plays the role of a counterweight wheel. The driven wheel 4 is heavy, which can increase the inertia of the entire transmission device, ensuring that the shear force of the cutting head 1 is large enough, and the large diameter of the driven wheel 4 can increase the torque and ensure the output stability.

[0025] Furthermore, a knife seat 10 is fixed above the slide rail 9, and the cutting knife head 1 is fixed on the knife seat 10 through a knife holder 11, and the knife holder 11 is detachably connected to the knife seat 10 through bolts, so that it is easy to inspect, maintain and replace.

[0026] Furthermore, the cutting head 1 is provided with a limiting surface 1.1 for limiting the position of the wire rack, the limiting surface 1.1 is below the cutting surface 1.2, and the limiting surface 1.1 is perpendicular to the cutting surface 1.1 of the cutting head. First, one end of the wire rack frame is placed against the limiting surface 1.1, and the wire rack is manually moved at a constant speed, and the wire ends exceeding the frame are cut as the cutting head is quickly raised and lowered. After the wire rack moves the entire length of the frame, all the wire ends exceeding the frame are cut.

[0027] Furthermore, a support platform 12 for placing a wire rack is provided on one side of the cutting head 1, and the upper surface of the support platform 12 is inclined. The support platform 12 provides support for the wire rack, and the inclined surface is convenient for movement and cutting. The pointed head formed after cutting is polished smooth by an angle grinder.

[0028] Furthermore, the wire rack cutting mechanism also includes a fixing frame 13 , and the driving device is assembled in the fixing frame 13 .

[0029] Furthermore, a guide channel 14 for the slide rail to be lifted and lowered is provided in the fixing frame 13 .

[0030] Furthermore, a closed baffle for protecting the driving device is formed on the upper surface of the fixing frame 13, and the baffle covers the driving device. The closed baffle can prevent the cut wire ends from falling into the driving device and causing damage to the device. The baffle can be tilted to allow the cut wire ends to slide to a designated area for easy cleaning and recycling.
