Description

Technical Field

[0001] This utility model relates to the field of artificial turf technology, specifically to an artificial turf positioning and cutting device. Background Technology

[0002] Artificial turf is a man-made ground cover material that resembles natural grass in appearance and function. It is usually made of materials such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC) and formed into fibers similar to natural grass blades through special production processes, such as injection molding or weaving. During the processing or installation of artificial turf, it needs to be cut into appropriate lengths and sizes. This is generally done manually with shears or knives. When cutting, the artificial turf should not be pressed down, as this can easily cause it to shift. In addition, the turf is susceptible to uneven cuts due to hand tremors, pulling forces, and external forces, which can affect the quality and aesthetics of the product. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an artificial turf positioning and cutting device, which solves the problems that operators cannot press down on the artificial turf during cutting, making it prone to displacement, and that uneven cuts are easily caused by hand tremors, pulling forces, and external forces.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an artificial turf positioning and cutting device, comprising an operating table, on which two parallel guide rails are mounted, a support frame and an installation frame are slidably connected, a pressing mechanism for pressing and positioning the artificial turf is installed inside the support frame, fixed seats are fixedly connected to both sides of the upper end of the installation frame, a lead screw is rotatably connected between the two fixed seats, a movable seat is threaded onto the lead screw, the lower end of the movable seat passes through a sliding groove opened on the support frame, and an installation plate is fixedly connected to the lower end of the movable seat, and a cutting blade is provided on the installation plate.

[0005] The above structural design allows the support frame and mounting frame to slide along the guide rails. The screw rotation drives the moving seat, mounting plate and cutting blade to move, which can flexibly adjust the cutting position to adapt to different sizes of artificial turf. At the same time, the pressing mechanism presses and positions the artificial turf, effectively preventing the turf from shifting during cutting and improving cutting accuracy and product quality.

[0006] Preferably, the pressing mechanism includes a bidirectional lead screw rotatably connected between the support frame, a movable block symmetrically threaded at the positive and negative threads of the bidirectional lead screw, a push rod rotatably connected to the side wall of the movable block, and the lower end of the push rod hinged to the pressure plate through a connecting seat.

[0007] The above structural design utilizes the positive and negative threads of a two-way lead screw to drive two moving blocks to move in opposite directions. Through push rod transmission, the pressure plate presses down on the artificial turf. The structure is simple and the pressing process is stable and controllable. It can effectively prevent the artificial turf from slipping during cutting and provide a stable positioning foundation for neat cutting.

[0008] Preferably, a slide rail is fixedly connected vertically to the side wall of the mounting plate, a slider is slidably connected to the slide rail, the cutting blade is installed at the lower end of the slider, a turntable is rotatably connected to the side wall of the mounting plate, a connecting rod is rotatably connected at an eccentric position on the turntable, and the lower end of the connecting rod is rotatably connected to the slider.

[0009] The above structural design utilizes a crank-slider mechanism consisting of a turntable, connecting rod, and slider to drive the cutting blade. This mechanism controls the blade's up-and-down movement, allowing it to extend from the bottom of the mounting plate when cutting is needed, ensuring a clean and precise cut of the grass fibers and adhesive backing, resulting in a smooth edge. When cutting is not required, the blade retracts, facilitating the movement of the mounting frame. Compared to manual cutting, this method is more efficient and produces better results.

[0010] Preferably, a protective cover is fixedly connected to the side wall of the mounting plate, the protective cover covers the outside of the cutting blade and the cutting blade can extend from the bottom of the protective cover.

[0011] With the above structural design, the protective cover is placed on the outside of the cutting blade. On the one hand, it can prevent operators from directly contacting the cutting blade and improve the safety of the device. On the other hand, it can provide a certain degree of protection for the cutting blade when the device is not in use.

[0012] Preferably, a rotating motor is installed on one side of the fixed base, and one end of the lead screw passes through the fixed base and is connected to the output end of the rotating motor.

[0013] By adopting the above structural design, the movement of the cutting blade is controlled by rotating a motor to drive a lead screw, thus achieving electrification of the cutting process. This ensures that the cutting blade can move smoothly and at a constant speed along the guide rail, completely avoiding problems such as uneven speed and vibration that may occur with manual feeding. This ensures the straightness of the cut and the stability of the overall cutting quality, improving the degree of automation and production efficiency.

[0014] Preferably, one end of the bidirectional lead screw passes through the side wall of the support frame and is equipped with a self-locking handwheel.

[0015] The above structural design utilizes a self-locking handwheel to drive the bidirectional lead screw, making operation simple and effortless. The self-locking mechanism prevents the bidirectional lead screw from reversing due to vibration or the reaction force of the lawn after the pressure plate position is adjusted and clamping force is applied. This ensures that the clamping force remains effective throughout the cutting process, preventing the pressure plate position from loosening and guaranteeing reliable fixation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention integrates the pressing and cutting mechanisms into a movable frame consisting of guide rails, a support frame, and an installation structure, enabling precise positioning of the artificial turf before cutting. During operation, the entire device is first moved to the predetermined cutting position, then the pressing mechanism presses and secures the turf, and finally the cutting blade is driven to cut. This structure effectively solves the problems of turf displacement and uneven cuts caused by hand tremors and pulling during manual cutting, significantly improving cutting accuracy, product quality, and aesthetics, while also making operation more convenient and labor-saving.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides an artificial turf positioning and cutting device, including an operating table 1. Two parallel guide rails 2 are installed on the operating table 1. The guide rails 2 guide the sliding of a support frame 3 and a mounting frame 4, allowing them to move smoothly along the length of the guide rails 2 to accommodate the cutting needs of artificial turf of different lengths. The support frame 3 and the mounting frame 4 are slidably connected to the guide rails 2. The support frame 3 is mainly used to install a pressing mechanism for pressing and positioning the artificial turf; the mounting frame 4 is used to support cutting-related components. Both the support frame 3 and the mounting frame 4 are portal frames. A guide rail locking mechanism is provided at the bottom of the support frame 3 and the mounting frame 4. The guide rail locking mechanism includes a locking bolt (not shown) that penetrates the bottom slider of the frame. The end of the locking bolt can press against the surface of the guide rail 2. When the locking bolt is tightened, its end generates a large frictional force with the surface of the guide rail 2, thereby firmly locking the support frame 3 or the mounting frame 4 in its current position, preventing accidental movement of the entire device during the cutting process and ensuring the accuracy of the cutting position.

[0025] The support frame 3 is equipped with a pressing mechanism for pressing and positioning the artificial turf. The pressing mechanism includes: a bidirectional lead screw 601 rotatably connected between the support frame 3, and two moving blocks 602 symmetrically threaded to the positive and negative threads of the bidirectional lead screw 601. Each moving block 602 has two parallel push rods 603 rotatably connected to its side wall. A pressure plate 5 is hinged to the lower end of the push rod 603 through a connecting seat.

[0026] When the artificial turf needs to be pressed and positioned, the self-locking handwheel 604 is turned to rotate the bidirectional lead screw 601. The forward and reverse threads of the bidirectional lead screw 601 drive the two moving blocks 602 to move in opposite directions, which in turn, through the transmission of the push rod 603, causes the pressure plate 5 to move downward until it is tightly pressed against the surface of the artificial turf, thus achieving stable positioning of the artificial turf. Moreover, the self-locking mechanism can prevent the bidirectional lead screw 601 from reversing due to external force after the pressure plate 5 is adjusted to the correct position, ensuring the reliability of the pressing.

[0027] The mounting bracket 4 has fixed seats 11 on both sides of its upper end. A screw rod 12 is rotatably connected between the two fixed seats 11. A movable seat 14 is threaded onto the screw rod 12. The lower end of the movable seat 14 passes through a long strip groove (not shown in the figure) opened on the support frame 3. The lower end of the movable seat 14 is fixedly connected to a mounting plate 10. A cutting blade 7 is provided on the mounting plate 10.

[0028] A rotary motor 13 is mounted on one side of the fixed base 11. One end of the lead screw 12 passes through the fixed base 11 and is connected to the output end of the rotary motor 13. When the rotary motor 13 is working, it can drive the lead screw 12 to rotate, thereby driving the movable base 14 to move along the length direction of the lead screw 12, so as to realize the position adjustment of the mounting plate 10 and the cutting blade 7, so as to accurately align with the area to be cut.

[0029] A slide rail 901 is vertically fixedly connected to the side wall of the mounting plate 10, and a slider 902 is slidably connected to the slide rail 901. The cutting blade 7 is installed at the lower end of the slider 902 by bolts or other fasteners. On the same side wall of the mounting plate 10, a turntable 904 is rotatably connected via a bearing. The turntable 904 is driven to rotate by a drive motor 905 installed on the side wall of the mounting plate 10. A connecting rod 903 is rotatably connected at an eccentric position on the turntable 904, and the lower end of the connecting rod 903 is rotatably connected to the slider 902.

[0030] When cutting is required, the turntable 904 is driven to rotate by the drive motor 905. The eccentric rotation of the turntable 904 will drive the slider 902 to move downward along the slide rail 901 through the connecting rod 903, thereby causing the cutting blade 7 to extend out of the lower end of the mounting plate 10, contact the artificial turf and complete the cutting action of the artificial turf.

[0031] A protective cover 8 is fixedly connected to the side wall of the mounting plate 10. The protective cover 8 covers the outside of the cutting blade 7. The top and bottom of the protective cover 8 are open to ensure that the cutting blade 7 can extend out from it to perform the cutting task when it moves downward. The protective cover 8 can prevent the operator from directly contacting the cutting blade 7 during the operation of the device, thus improving the safety of use. On the other hand, when the cutting blade 7 is not working, it can protect the cutting blade 7 and reduce the damage to the cutting blade 7 caused by external factors.

[0032] Working principle:

[0033] First, lay the artificial turf flat on the operating table 1. Based on the desired cutting position, push the support frame 3 and mounting frame 4 to slide them along the guide rail 2 to the appropriate area and fix them in place. Simultaneously, start the rotating motor 13, driving the lead screw 12 to rotate, which in turn moves the moving seat 14, mounting plate 10, and cutting blade 7 to further precisely align the cutting position. Rotate the self-locking handwheel 604 to rotate the bidirectional lead screw 601. Through the transmission of the moving block 602 and push rod 603, the pressure plate 5 moves downwards and presses the artificial turf. The self-locking mechanism locks the position of the bidirectional lead screw 601, ensuring the artificial turf does not shift during the cutting process. The drive turntable 904 rotates, and the connecting rod 903 drives the slider 902 to slide down along the slide rail 901, so that the cutting blade 7 extends from the bottom of the protective cover 8 and descends to the cutting depth and is fixed. Then, the drive motor 13 is controlled to slowly and uniformly drive the lead screw 12, so that the cutting blade 7 moves smoothly in the middle of the pressing area formed by the pressure plate 5 to complete the entire section cutting. After the cutting is completed, the cutting blade 7 can be retracted into the protective cover 8, the pressure plate 5 is released, the device is removed, and the cut artificial turf is taken out.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
