The cloth support plate is mounted on the frame, and the needle seat is arranged in parallel directly above the cloth support plate. The needles are multiple and evenly spaced and fixed on the needle seat close to the cloth support plate. A plurality of cloth support plate holes for the needles to pass through are provided on the cloth support plate to match the positions of the needles. The secondary hook base is arranged below the cloth support plate, and the secondary hook knife is the same in number as the needles and is fixed at equal intervals. On the side of the auxiliary hook base close to the cloth support plate, the main hook base is arranged parallel to the bottom of the cloth support plate, there are multiple main hook knives and they match the auxiliary hook knives, and the main hook knives are fixed on the side of the main hook base close to the auxiliary hook base. The tufting machine also includes a needle seat driving mechanism for driving the needles driven by the cloth support plate to move up and down along the holes of the cloth support plate, a main hook driving mechanism for driving the main hook base to move forward and backward to drive the main hook knife to take or release the thread from the needle, an auxiliary hook driving mechanism for driving the auxiliary hook base to move forward and backward to drive the auxiliary hook knife to take or release the thread from the main hook knife, and a main driving mechanism for driving the needle seat driving mechanism, the main hook driving mechanism and the auxiliary hook driving mechanism to be linked.

[0003] The existing structure of the tufting machine, i.e., the lawn machine and its tufting device have the following disadvantages in the actual production process: when the machine is shut down or the needle bed temporarily stops moving for reasons such as changing the work station, the yarn tube wound with the grass yarn is passively fed, and the tension of the grass yarn is uncontrollable. The grass yarn between the yarn tube and the tufting needle, especially the grass yarn at the tufting needle, will become very loose and in a state of no working tension. As a result, when the machine is turned on or the needle bed continues to work, the tufting needle flocks or the cutting knife cuts the yarn in place or inaccurately, and even flocking and cutting failures occur, which seriously reduces the quality of the finished lawn product. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a tufting device for an artificial turf machine that can ensure that the grass yarn at the tufting needle is in a working tension state when the needle bed temporarily stops moving due to reasons such as shutdown or changing workstations, thereby preventing the grass yarn at the tufting needle from becoming loose and having no tension and causing flocking and cutting failures, thereby improving the quality of the finished lawn product.

[0007] As a preferred embodiment of the present invention, the first connecting block is a T-shaped connecting block with a T-shaped cross-section, the second connecting block is a half, the slot plate mounting seat is an angle iron shape, the first connecting block is fixedly connected to the second connecting block by bolts, and the slot plate mounting seat is fixedly connected to the first connecting block by bolts.

[0008] As a preferred embodiment of the present invention, the first connecting block is a guide rail, the second connecting block is a slider, the slot plate mounting seat is in the shape of an angle iron, the first connecting block is slidably connected to the second connecting block, and the slot plate mounting seat is fixedly connected to the first connecting block by bolts.

[0009] As a preferred embodiment of the present invention, the first connecting block and the second connecting block are slidably connected via a dovetail groove, a triangular groove, a trapezoidal groove, or a rectangular groove structure.

[0010] As a preferred embodiment of the present invention, the first driving mechanism includes a motor, and the needle bed movement mechanism also includes a rotating shaft, an eccentric wheel and an eccentric sleeve connecting rod. The rotating shaft is rotatably mounted on the oil tank side plate of the lawn mower and is driven to rotate by the motor. The eccentric wheel is fixedly mounted on the rotating shaft, the upper end of the eccentric sleeve connecting rod is sleeved on the eccentric wheel, the lower end of the eccentric sleeve connecting rod is rotatably connected to the upper end of the output shaft, and the output shaft is slidably matched with the oil tank bottom plate of the lawn mower.

[0011] As a preferred embodiment of the present invention, the second driving mechanism includes a cylinder or a linear motor, and one end of the transverse strip is connected to the output shaft of the cylinder or the linear motor.

[0012] As a preferred embodiment of the present invention, the hole spacing between the first through holes, the hole spacing between the second through holes, and the hole spacing between the third through holes are equal.

[0013] As a preferred embodiment of the present invention, the cross-section of the groove plate is concave-shaped, and the tufting device also includes a plurality of pressure blocks, which are installed at intervals on the opening side of the groove along the length direction of the groove plate, and the transverse strip plate is matched with the pressure blocks and the groove gap.

[0014] After adopting the above structure, the present invention has the following beneficial effects: The present invention provides a slot plate, a transverse strip plate and a second driving mechanism. The slot plate is in an elongated strip shape and has a horizontally arranged top plate and a bottom plate. A groove is provided between the top plate and the bottom plate. The top plate is provided with a first through hole along the length direction, and the bottom plate is provided with a second through hole along the length direction. The first through hole and the second through hole are arranged correspondingly up and down. The transverse strip plate is in an elongated strip shape and has a third through hole along the length direction. The transverse strip plate is placed in the groove and the third through hole is arranged correspondingly up and down to the first through hole and the second through hole. The transverse strip plate is driven to move transversely by the second driving mechanism. During normal operation, the grass silk yarn is unwound from the yarn tube, passes through the first through hole on the top plate of the slot plate, the third through hole on the transverse strip plate and the second through hole on the bottom plate of the slot plate in turn, and then enters the tufting needle to realize normal flocking weaving; when the machine is shut down or the needle bed temporarily stops moving for reasons such as changing the work station, the second driving mechanism drives the transverse strip plate to move horizontally for a distance, so that the third through hole is misaligned with the first through hole and the second through hole, and the third through hole no longer corresponds to the first through hole and the second through hole up and down, so that the grass silk yarn is locked by the folded angle between the first through hole and the third through hole and the folded angle between the second through hole and the third through hole. At this time The grass yarn can neither advance nor retreat, thereby effectively preventing the grass yarn at the tufting needle from being loose and tensionless, ensuring that the grass yarn at the tufting needle is in a working tension state. When the machine is turned on or the needle bed continues to work, the second driving mechanism drives the transverse moving plate to move in the opposite direction by a corresponding distance, so that the transverse moving plate returns to its original initial position again, that is, the third through hole corresponds to the first through hole and the second through hole above and below. The present invention keeps the grass yarn tension in a controllable state, effectively avoiding the tufting needle from flocking or the cutting knife from cutting the yarn inadequately or inaccurately, preventing malfunctions during flocking and cutting, and improving the quality of finished lawn products.

[0015] The present invention installs a first connecting block on the upper end of the needle bed, and the slot plate is installed on the slot plate mounting seat. The slot plate mounting seat is fixedly connected to the first connecting block. When working, the slot plate moves with the needle bed. Such a structure can better, more conveniently and more accurately control the tension of the grass yarn at the tufting needle, and the quality of the finished lawn product is better.

[0016] The first connecting block and the second connecting block of the present invention can be fixedly connected or slidably connected. When the two are fixedly connected, single-color flocking can be achieved; when the two are slidably connected, the needle bed can be driven to move laterally by the lateral driving mechanism to achieve double-color flocking. The present invention is applicable to a wide range of machine models.

[0017] In the present invention, the hole spacing between the first through holes, the hole spacing between the second through holes, and the hole spacing between the third through holes are equal. Such a structure, on the one hand, makes the processing of the groove plate and the transverse strip plate more convenient and the manufacturing cost lower. On the other hand, the grass silk yarn can pass through the first, second and third through holes more smoothly.

[0018] The invention has a simple structure and is convenient to process and operate. BRIEF DESCRIPTION OF THE DRAWINGS
