DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The tubular package in the utility model can be a packaging hose for toothpaste, facial cleanser, hand cream and other pastes, and the end of the tubular package is the tube tail that has been sealed by a heat sealer. The knife holder assembly of the utility model is used to replace the existing knife holder assembly and is connected to the shearing device.

[0027] A tool holder assembly includes a cutter 1, a cutter 2, a tool holder 1 3 and a tool holder 2 4, wherein the cutter 1 and the cutter 2 are respectively provided with a convex block 305 and a groove 401 of a predetermined shape, wherein the convex block 305 and the groove 401 match each other; the cutter 1 and the cutter 2 are respectively fixed on the tool holder 1 3 and the tool holder 2 4; and the tool holder 1 3 is provided with a deformation seam 301 on both the left and right sides above the cutter 1. The purpose of providing the deformation seam 301 is to allow the cutter 1 to have a space for rising and falling, and the cutter 1 and the cutter 2 are interference fit. In the process of shearing the tail of a tubular packaging tube, due to the existence of the deformation seam 301, when the convex block 305 and the groove 401 on the cutter 1 and the cutter 2 are engaged, i.e., shearing, the surface tangent to the groove 401 and the convex block 305 can be pressed tightly, thereby ensuring the formation of a sufficiently large shearing force, and the deformation seam effectively protects the cutter and reduces the wear of the blade. The tool holder and the cutter are both made of metal materials, and the deformation seam is cut by wire cutting.

[0028] like Figure 1 , 3, 4 show a tool holder assembly, the groove 401 and the protrusion 305 are both U-shaped, the tail of the tube package is placed between the cutter 1 and the cutter 2, when the tool holder 1 3 and the tool holder 2 4 reach a clamping or shearing state under the drive of the power mechanism, the shearing force formed can cut the tail of the tube package from one side to the other side and shear it into the desired U shape.

[0029] Preferably, the deformation joint includes a linear deformation joint 3013 and a linear deformation joint 3011, the linear deformation joint 3013 and the linear deformation joint 3011 are staggered, the linear deformation joint 3013 is provided with a semi-closed deformation joint 1 on the side facing the linear deformation joint 2, the linear deformation joint 3013 is connected to the semi-closed deformation joint 1, and the linear deformation joint 2 3011 is not connected to the semi-closed deformation joint 1; the linear deformation joint 2 3011 is connected to the semi-closed deformation joint 2 3012, the semi-closed deformation joint 2 3012 is not connected to the semi-closed deformation joint 1 and the linear deformation joint 1 3013, and a part of the semi-closed deformation joint 1 is included in the semi-closed deformation joint 2 3012.

[0030] Preferably, in order to prevent stress concentration from occurring at the end of the deformation seam located in the tool holder during use, the cross-section of the deformation seam end 3014 is arc-shaped.

[0031] Preferably, a conical hole 3015 is provided on the second semi-closed deformation joint 3012, and a screw is screwed into the conical hole 3015, and the elasticity of the tool holder can be adjusted according to the tightening condition of the screw.

[0032] Preferably, it also includes a slide rail 1, and the tool holder 1 3 and the tool holder 2 4 are both slidably connected to the slide rail. Figure 1 As shown, a slider is provided under the tool holder 1 3 and the tool holder 2 4, and the slider is slidably connected to the slide rail 1 to limit the running trajectory of the tool holder 1 3 and the tool holder 2 4 to ensure that the two will not be misaligned.

[0033] Preferably, a scrap material discharge outlet 306 is provided below the tool holder 1 3 , and a blowing device (not shown in the figure) is provided on the tool holder 2 4 , and the blowing device provides an air source through a high-pressure air pump, and the blowing port on the blowing device is arranged corresponding to the scrap material discharge outlet 306 .

[0034] Preferably, an extension plate facing the knife holder 2 4 is provided on the knife holder 1 3 below the cutter 1. The extension plate can be used to support the tube tail of the tubular packaging. When the tube tail is cut, the scraps will fall on the extension plate and be quickly blown into the scrap discharge port 306 by the blowing device.

[0035] Preferably, the tool holder 1 3 is provided with an arc-shaped baffle 302 with an opening facing outward. Figure 1 As shown, the arc-shaped baffle 302 is connected to the tool holder 3 through an angle plate 304, and an oblong through hole 303 is provided on the angle plate 304.

[0036] Preferably, the front surface of the cutter 1 is inclined. Figure 4 As shown, the cutter 1 is a right-angle trapezoid in a top view. When the cutter 1 and the cutter 2 are in a non-shearing state, the front surface of the cutter 1, i.e., the surface of the cutter 1 facing the cutter 2, is an inclined surface. The front surface of the cutter 1 is not perpendicular to its motion track, i.e., the slide rail 1. This arrangement reduces the contact length of the cutter 1 with the pipe tail during the shearing process, which is beneficial to reducing the shearing resistance and ensuring the size of the shearing knife.

The knife holder 1 3 and the knife holder 2 4 are both slidably connected to the slide rail 1, the swing rod 2 is rotatably connected to the slide rail 1, the upper end of the swing rod 2 is provided with a limit groove, and the knife holder is provided with a limit rod 307 matching the limit groove, and the lower end of the swing rod 2 is connected to a power mechanism (not shown in the figure). Under the drive of the power mechanism, the groove 401 and the protrusion 305 switch between the shearing and non-shearing states. When the groove 401 and the protrusion 305 are engaged, that is, shearing, a shearing force is formed to shear the tail of the packaging hose located between the two. The power mechanism can be a hydraulic swing motor, which is fixedly connected to the lower end of the swing rod 2. Driven by the swing motor, the swing rod 2 can swing back and forth, drive the knife holder to move in the horizontal direction, and shear the end of the packaging tube; the power mechanism can also be a cylinder, which directly drives the knife holder to move through the cylinder to achieve shearing, or other power mechanisms that can achieve the same function, which are not listed one by one here.
