Description

Technical Field

[0001] The utility model relates to the technical field of geogrid processing, in particular to a cutting device for geogrid processing. Background Art

[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials. Geogrids are divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp-knitted polyester geogrid. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of high molecular polymers such as polypropylene and polyvinyl chloride through thermoplasticization or molding. When used in civil engineering, it is called geogrid. Geogrids need to be cut to the appropriate size using cutting equipment for subsequent use.

[0003] According to the Chinese utility model disclosure number CN215093877U, a cutting device for producing geogrids is disclosed. It includes a frame, the frame includes a base and side panels arranged on the front and rear sides of the base, and limit blocks are symmetrically arranged on the outer side walls of the two side panels, and a U-shaped bracket arranged perpendicular to the direction of the side panels is movably connected to the outer side walls of the two side panels. The U-shaped bracket includes a crossbeam and a vertical beam arranged at the bottom of both ends of the crossbeam, and a slide groove is provided on the side walls on the opposite side of the two vertical beams along the height direction. It has a reasonable structural design and is easy to operate. It adopts a downward pressure cutting method, which fundamentally eliminates the generation of debris, avoids waste, and will not damage the fiberglass geogrid, reducing unnecessary cost expenditures, and can quickly complete the cutting process, so that the incision of the fiberglass geogrid is neat and uniform, thereby improving the quality of the product and solving the problems existing in the prior art.

[0004] The above disclosed method uses downward pressure to cut the geogrid, which reduces the debris generated during cutting. However, the geogrid passing through the driven roller lacks a guide mechanism, which makes the geogrid easy to deviate when it is transported to the bottom of the cutting mechanism. The geogrid fixed by the clamping plate is in an inclined state, which will cause the cut made by the knife head to be skewed, affecting the quality of the geogrid product. Utility Model Content

The pressing mechanism 26 includes: a plate body 261, symmetrically arranged on the opposite surfaces of the side plates 12; an electric push rod 262, fixedly connected to the bottom of the plate body 261; a support block 263, fixedly connected to the bottom output end of the electric push rod 262; an upper guide roller 264, rotatably connected between the support blocks 263, and the upper guide roller 264 passes through the two through holes 241. The inner wall of the through groove provided on the base 11 for the top plate 13 to move is fixedly connected with bristles 4, and the bristles 4 are arc-shaped.

[0050] When in use, the staff first adjusts the spacing of the guide plates 24 according to the width of the geogrid: the hand wheel 23 is turned, and the hand wheel 23 drives the bidirectional screw 22 to rotate. The guide plates 24 threadedly connected to the bidirectional screw 22 are close to or separated from each other according to the different directions of the bidirectional screw 22, thereby controlling the direction of the hand wheel 23 and the number of turns to adjust the spacing of the guide plates 24 to be slightly larger than the width of the woodworking grid. The guide plates 24 guide the movement of the geogrid to avoid skewing, and then control the electric push rod 262 in the pressing mechanism 26 to make the upper guide roller 264 away from the lower guide roller 2 5: The staff controls the electric push rod 262 to retract, and the electric push rod 262 drives the support block 263 and the upper guide roller 264 to move upward, and the distance between the upper guide roller 264 and the lower guide roller 25 becomes larger, and one end of the woodworking grid passes through it, and the woodworking grid is pulled and laid flat on the base 11, and the electric push rod 262 is controlled to extend, and the upper guide roller 264 moves downward to prevent the woodworking grid from arching upward, and then the hydraulic rod 14 is controlled to extend downward, and the cutting mechanism 15 cuts the geogrid, and the cut geogrid stays on the conveying roller 27, which is convenient for the staff to collect. The cutting mechanism 15 mentioned above adopts a conventional cutting method, for example, the cutting mechanism 15 can be driven by the cutting knife to move up and down, as long as it can achieve the cutting of the woodworking grid, the specific structure will not be repeated here. The cutter in the cutting mechanism 15 passes through the through slot on the base 11 when cutting downwards, and the arc-shaped bristles 4 on the inner wall of the through slot contact the outer wall of the cutter. When the cutter is lifted upwards, the bristles 4 take the debris remaining on the outer wall of the cutter away from the cutter, avoiding the cutter from being stuck with debris and affecting its next cutting.

[0051] Embodiment 2

[0052] On the basis of the first embodiment, an auxiliary function is added.

[0053] See also Figure 1-4 The hydraulic rod 14 is provided with a fixing assembly 3, which includes: a support plate 31, which is sleeved on the outside of the output shaft of the hydraulic rod 14; an optical axis 32, which is set through the support plate 31; a pressure plate 33, which is set at the bottom of the optical axis 32; a spring 34, which is fixedly connected between the support plate 31 and the pressure plate 33, and the spring 34 is sleeved on the outside of the optical axis 32; and a limit plate 35, which is fixedly connected to the top of the optical axis 32.

The bottom of the pressure plate 33 is provided with anti-slip grooves.

[0054] The fixing assembly 3 fixes the geogrid when the cutting mechanism 15 is cutting: when the hydraulic rod 14 extends downward, the support plate 31 moves downward, and when the pressure plate 33 contacts the surface of the geogrid, the hydraulic rod 14 continues to move downward, and the support plate 31 slides downward on the optical axis 32 close to the pressure plate 33, and compresses the spring 34. The reaction force of the spring 34 presses the pressure plate 33 against the geogrid, and the position of the geogrid is fixed, which facilitates the cutting mechanism 15 to continue cutting. The optical axis 32 and the spring 34 are provided in multiple groups, so that the pressure plate 33 is evenly stressed, and the pressure plate 33 is prevented from tilting when stressed, which facilitates the fixing of the geogrid. The anti-slip grooves at the bottom of the pressure plate 33 increase the friction between the contact surface of the pressure plate 33 and the geogrid, so that the geogrid is better fixed.
