Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and more particularly to a V-grooving machine. Background Technology

[0002] In the process of assembling packaging boxes, folding of the boxes is often involved. The current practice is to use a knife to punch multiple notches in the material used to make the box to facilitate subsequent 90° folding. However, this punching method will flatten the material used to make the box, such as pearl cotton, sponge, corrugated paper, etc. Utility Model Content

[0003] To solve the above problems, this utility model provides a V-shaped grooving machine with a V-shaped cutter head. Combined with the lateral cutting method of horizontal movement, it can prevent the box from being flattened.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a V-shaped grooving machine, comprising a cutting platform that performs reciprocating motion, characterized in that, above the cutting platform, there is also a cutter mounted on a cantilever, the cutter comprising a cutter holder and a set of blades, the blades being symmetrically arranged on the surface of the cutter holder facing the box, the blades being arranged at an inclination so that their tips abut against each other, so that the same side of the blades forms a V-shaped cutting blade.

[0005] Furthermore, the cutting tool includes a height adjustment mechanism, which includes a guide shaft, a rack, a worm gear mechanism, a first handwheel, and a mounting base. The mounting base has a cavity, and the worm gear mechanism, rack, and guide shaft are disposed within the cavity. The rack is disposed on the side wall of the guide shaft and meshes with the transmission teeth on the worm gear mechanism. The worm and guide shaft extend outside the mounting base, and the worm is connected to the first handwheel. The tool holder is disposed on the end of the guide shaft.

[0006] Furthermore, it also includes a clamping assembly disposed on the cutting platform, the clamping assembly comprising a clamping bar and a first lifting cylinder, the clamping bar being provided in at least one set and distributed on both sides of the cutter in a symmetrical arrangement centered on the cutter.

[0007] Furthermore, the clamping assembly also includes a second height adjustment mechanism and a cylinder fixing plate. The first lifting cylinder is mounted on the cylinder fixing plate. The second height adjustment mechanism includes a pressure screw, a nut assembly, and a drive mechanism. The side of the nut assembly is connected to the cylinder fixing plate. The pressure screw is threadedly connected to the nut assembly. The output end of the drive mechanism is connected to the pressure screw.

[0008] Furthermore, the drive mechanism includes a second handwheel, a chain, a driven gear, a clamping assembly, and two driven gears. The driven gears are respectively sleeved on the pressure screws in the clamping assembly, the chain is sleeved on the driven gears, and the second handwheel is connected to one of the pressure screws.

[0009] The beneficial effects of this utility model are:

[0010] This invention first improves the design of the cutting tool so that it cuts grooves in the box from the side. In this way, the force of the cutting tool is only applied to the side of the box and not directly to the surface of the box, ensuring that the box will not be flattened due to pressure on the surface.

[0018] Figure 8 yes Figure 7 Enlarged diagram of point C. Detailed Implementation

[0019] like Figure 1-8 As shown, this utility model is a grooving machine, specifically a V-shaped grooving machine, wherein the V-shape refers to the V-shaped groove used to prepare the box material.

[0020] The aforementioned V-grooving machine includes a cutting platform 1 and a cantilever 2 positioned above the cutting platform 1. The surface of the cutting platform 1 is the cutting surface, and a cutting tool is connected to the end of the cantilever 2. The cutting platform 1 provides a multi-dimensional movement trajectory. By adjusting the position of the plate, the cutting tool can smoothly reach the designated position of the plate (the material used to prepare the box) and cut the plate.

[0021] The blade holder 31 has a V-shaped cutting blade. Specifically, the cutting blade is composed of a set of blades 32. The blades 32 are arranged symmetrically on the surface of the blade holder 31 facing the box. The blades 32 are arranged at an angle so that their tips abut against each other, so that the same side of the blades 32 forms a V-shaped cutting blade.

[0022] This configuration primarily provides a side-cutting method, satisfying the requirement of cutting from the side. In this way, the force of the blade only acts on the side of the box, and will not directly act on the surface of the box, ensuring that the box will not be flattened due to surface pressure.

[0023] The cutting platform 1 moves back and forth laterally, so the initial position of this tool, whether on the left or right side of the board, can cut the board in a timely manner.

[0024] Furthermore, the cutting tool includes a height adjustment mechanism, which comprises a guide shaft 41, a rack 42, a worm gear mechanism, a first handwheel 44, and a mounting base 45. The mounting base 45 has a cavity, and the worm gear mechanism, rack 42, and guide shaft 41 are disposed within the cavity. The rack 42 is connected to the side wall of the guide shaft 41 and meshes with the transmission teeth on the worm gear mechanism. The worm 43b and the guide shaft 41 extend outside the mounting base 45, and the worm 43b is connected to the first handwheel 44. The tool holder 31 is disposed on the end of the guide shaft 41. Its main purpose is to adjust the height of the cutting tool. Since the plates have different thicknesses, selecting the corresponding height is necessary to cut the corresponding grooves on the plates. Another purpose is to make it lightweight. The cantilever 2 is arc-shaped, which does not put a large load on the end of the cantilever 2. An excessively heavy design would cause the cantilever 2 to bend, causing the groove to tilt.

[0025] The worm gear mechanism includes a turbine 43a and a worm 43b, which are connected by a transmission. The transmission teeth on the turbine 43a also mesh with the rack 42.

[0026] Furthermore, it also includes a clamping assembly, which includes a clamping bar 51 and a first lifting cylinder 52. The clamping bar 51 is provided in at least one set and is distributed on both sides of the cutter in a symmetrical arrangement with the cutter as the center. Since it is a lateral cut, the clamping bar 51 can prevent the plate from being lifted or displaced during the cut.

[0027] Furthermore, the clamping assembly also includes a second height adjustment mechanism and a cylinder fixing plate 53. The first lifting cylinder 52 is mounted on the cylinder fixing plate 53. The second height adjustment mechanism includes a pressure screw 54, a nut assembly 55, and a drive mechanism. The base 56 is connected to the cutting platform 1. The pressure screw 54 is mounted on the base 56 via a bearing. The pressure screw 54 is threadedly connected to the nut assembly 55. The side of the nut assembly 55 is connected to the cylinder fixing plate 53. The output end of the drive mechanism is connected to the pressure screw 54. Similarly, the clamping assembly needs to be adjusted according to the thickness of the sheet metal to ensure that the positioning effect is not weakened. At the same time, this design is for application on the side of the cutting platform 1, pressing the sheet metal against the side of the cutting platform 1.

[0028] Furthermore, this specific implementation method can be applied to manually driving two clamping components simultaneously:

[0029] The drive mechanism includes a second handwheel 57, a chain 58, and a driven gear 59. The clamping assembly and the driven gear 59 are provided in two. The driven gear 59 is respectively sleeved on the pressure screw 54 in the clamping assembly. The chain 58 is sleeved on the driven gear 59. The second handwheel 57 is connected to one of the pressure screws 54.

[0030] The multi-dimensional changes of the cutting platform 1 are achieved through the first linear moving mechanism, which is existing technology, so its structure will not be described in detail.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
