Description

Technical Field

[0001] The utility model relates to the technical field of handicraft manufacturing, in particular to a twisted wire cutting device. Background Art

[0002] The mini three-dimensional Christmas tree is mainly made by a wool twisting machine, which uses a V-shaped wire to clamp a row of thin plastic wool strips, and twists and pulls the wire through a rotating clamp group to make the plastic strips spread out in a circular shape and fixed by the twisted wire. This step is the embryo making, and finally the spread plastic strips are trimmed into a conical Christmas tree shape by pruning; the twisted wire is the trunk of the Christmas tree, and the thin plastic strips are the branches of the Christmas tree. After the rotating clamp group twists and pulls the wire to make the plastic wool spread out in a circular shape to form the blank of the mini Christmas tree, the bunch of mini Christmas tree blanks need to be cut when they reach a certain length so that they can be transferred to the next process. At present, the cutting of the wire is divided into two steps: first, the clamping mechanism is used to clamp the wire strands at the outer end, so that the wire in the clamping mechanism and the rotating clamp group can be twisted more tightly, and then the shearing mechanism is raised to clamp the wire from the inside of the clamping mechanism. The cut wire segments will automatically fall off to enter the next process.

[0003] However, the clamping mechanism and shearing mechanism in the current conventional wool twisting machines work separately and independently. Usually, the shearing mechanism will start to rise only after the clamping mechanism clamps the wire for a period of time. There is a delay between the start of the two, which leads to an unsmooth connection between the two when working, and may cause the wire to be damaged by excessive twisting. In addition, the clamping mechanism and the shearing mechanism operate separately and independently, which also leads to low structural integration and space utilization. Utility Model Content

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is 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 implementation disclosed below.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figure 1-4 As shown, the stranded wire cutting device provided in this embodiment includes a frame 1, and a rotating clamp group 11 is installed on the top of the frame 1. The rotating clamp group 11 can pull the wire to perform axial twisting and movement. The rotating clamp group 11 is an existing product structure in the wool twisting machine, so its specific structure is not described in detail here. The stranded wire cutting device also includes a base 2, a clamping mechanism 3 and a shearing mechanism 4.

[0030] like Figure 1 As shown, the base 2 is installed at the bottom of the frame 1.

[0031] like Figure 4 As shown, the clamping mechanism 3 includes a mounting seat 31 and a clamping rod 32. The mounting seat 31 is installed on the top of the base 2. Two mutually meshing gear shafts 33 are rotatably installed on the mounting seat 31. The upper sides of the two gear shafts 33 are provided with clamping rods 32. The top ends of the two clamping rods 32 are respectively located on both sides of the iron wire.

[0032] Specifically, a clamping block 321 is provided at the top of each of the two clamping rods 32, and an anti-skid layer is provided on one side of the two clamping blocks 321 close to each other. The anti-skid layer can be selected with uneven anti-skid patterns. When the two clamping rods 32 are rotated so that their top ends are close to each other, the two clamping blocks 321 can clamp the wire.

[0033] like Figure 2 and Figure 4 As shown, the shearing mechanism 4 includes a first telescopic cylinder 41 and a shearing assembly 42. The first telescopic cylinder 41 is installed on the top of the base 2 and is located on the side of the mounting base 31 close to the rotating clamp group 11. The telescopic shaft end of the first telescopic cylinder 41 faces upward and is provided with a bearing plate 43. A rack 44 meshing with one of the gear shafts 33 is installed on the bearing plate 43, and when the rack 44 moves upward, it can drive the top ends of the two clamping rods 32 close to each other through the two gear shafts 33. The shearing assembly 42 is installed on the top of the bearing plate 43 for cutting the wire.

[0034] During specific use, when the rotating clamp group 11 pulls the string of mini Christmas tree blanks to a certain length, the first telescopic rod 41 is started to move the supporting plate 43 upward, and the supporting plate 43 will drive the rack 44 to move upward synchronously, and then drive the top ends of the two clamping rods 32 to rotate and approach each other through the two gear shafts 33. When the supporting plate 43 rises to the top, the wire between the two clamping rods 32 is clamped, so that the rotating clamp group 11 can twist the wire between it and the clamping mechanism 3 more tightly, and when the supporting plate 43 rises to the top, the shearing assembly 42 will be aligned with the two sides of the wire, and then the shearing assembly 42 can be started to cut the wire.

[0035] It should be noted that the shearing assembly 42 needs to be located below the wire when it is not necessary to cut the wire, so as to avoid affecting the movement of the mini Christmas tree blank.

[0036] The utility model installs a rack 44 on the bearing plate 43 and meshes the gear shaft 33 with the rack 44, so that when the bearing plate 43 drives the shearing assembly 42 to move up to the shearing position, it can drive the two clamping rods 32 to clamp the wire, shortening the time delay between clamping the wire and cutting the wire, and making the connection between the two operations smoother. At the same time, the two steps are linked and combined with each other, which is beneficial to improving the structural integration of the device and improving space utilization.

[0037] like Figure 3 As shown, specifically, the shearing assembly 42 includes a back plate 421, a second telescopic cylinder 422 and a shearing rod 423, the back plate 421 is installed on the top of the supporting plate 43, a first hinge seat 424 is installed on one side of the back plate 421, two shearing rods 423 are rotatably installed on both sides of the first hinge seat 424 respectively, and the upper and lower ends of the two shearing rods 423 are bent to the side away from each other, and a shearing blade 425 is provided on the side close to each other at the top of the two shearing rods 423, the second telescopic cylinder 422 is installed on the top of the supporting plate 43 and is located between the two shearing rods 423, the telescopic shaft end of which faces upward and is installed with a second hinge seat 426, two support rods 427 are rotatably connected to the second hinge seat 426, and the distal ends of the two support rods 427 are rotatably connected to the bottom ends of the two shearing rods 423 respectively. During specific use, when the telescopic shaft end of the second telescopic cylinder 422 extends upward, it will drive the two support rods 427 to rotate and push the bottom ends of the two shear rods 423 to rotate outward, so that the top ends of the two shear rods 423 are close to each other, thereby enabling the two shear blades 425 to cut the wire.

[0038] It should be noted that both the first telescopic cylinder 41 and the second telescopic cylinder 422 may be hydraulic cylinders.

[0039] like Figure 1As shown, preferably, a blanking plate 12 is installed on the inner side of the frame 1 between the shearing mechanism 4 and the rotating clamp group 11, one end of the blanking plate 12 is connected to the top of one side of the frame 1 and the other end is connected to the bottom of the other side of the frame 1, so as to be inclined below the iron wire, and a conveyor belt 13 is installed at the bottom of the frame 1 at the lowest end of the blanking plate 12. When the iron wire of the mini Christmas tree blank is cut, it can fall to the conveyor belt 13 along the slope of the blanking plate 12, so as to be conveniently transferred to the next step.

[0040] Furthermore, since the plastic hair of the mini Christmas tree blank has a certain elasticity, in order to prevent the fallen mini Christmas tree blank from bouncing out of the conveyor belt 13, a baffle 14 is installed on the upper side of the conveyor belt 13, and a gap is left between the baffle 14 and the conveyor belt 13 and the lowest end of the unloading plate 12 to allow the mini Christmas tree blank to pass through.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
