Description

Technical Field

[0001] The utility model relates to a lawn mower for producing artificial turf, specifically to a tufting device in the lawn mower, and belongs to the technical field of textile equipment. Background Art

[0002] Existing lawn mowers for producing artificial turf, such as the structure disclosed in a Chinese utility model patent ZL202120975892.2, named a tufting machine for producing ground elastic turf, include a frame, a cloth support plate, a needle base, needles, a main hook base, a main hook knife, a secondary hook base, and a secondary hook knife. The cloth support plate is erected on the frame. The needle base is arranged parallelly directly above the cloth support plate. There are multiple needles fixed at equal intervals on the side of the needle base close to the cloth support plate. Multiple cloth support plate holes for the needles to pass through are arranged on the cloth support plate at positions matching the needles. The secondary hook base is arranged below the cloth support plate. The number of secondary hook knives is the same as that of the needles and they are fixed at equal intervals on the side of the secondary hook base close to the cloth support plate. The main hook base is arranged parallelly below the cloth support plate. There are multiple main hook knives which match the secondary hook knives, and the main hook knives are fixed on the side of the main hook base close to the secondary hook base. The tufting machine further includes a needle base driving mechanism for driving the up and down movement of the cloth support plate to drive the needles to move up and down along the cloth support plate holes, a main hook driving mechanism for driving the back and forth movement of the main hook base to drive the main hook knives to pick up or release yarn from the needles, a secondary hook driving mechanism for driving the back and forth movement of the secondary hook base to drive the secondary hook knives to pick up or release yarn from the main hook knives, and a main driving mechanism for driving the linkage of the needle base driving mechanism, the main hook driving mechanism, and the secondary hook driving mechanism.

[0003] The existing tufting machines, i.e., lawn mowers and their tufting devices, have the following disadvantages in the actual production process: when the machine stops or the needle bed temporarily stops moving for reasons such as changing workstations, since the yarn bobbin for winding the grass yarn is a passive yarn feeding, the tension of the grass yarn is uncontrollable. The grass yarn between the yarn bobbin and the tufting needles, especially the grass yarn at the tufting needles, will become very loose and in a state of no working tension, resulting in inaccurate tufting or cutting of the yarn by the tufting needles when starting work or the needle bed continues to work, and even tufting and cutting failures, seriously reducing the quality of the lawn finished product. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a tufting device for an artificial turf lawn mower that can ensure that the grass yarn at the tufting needles is in a working tension state when the machine stops or the needle bed temporarily stops moving for reasons such as changing workstations, prevent the grass yarn at the tufting needles from being loose and without tension and tufting and cutting failures, and improve the quality of the lawn finished product.

[0005] To solve the above technical problems, the present utility model adopts a tufting device for an artificial lawn mower, which includes a needle bed, tufting needles vertically installed on the needle bed, and a needle bed movement mechanism for driving the movement of the needle bed.

The transverse moving strip plate is placed in the groove, and the third through holes are vertically corresponding to the first through holes and the second through holes. The transverse moving strip plate is driven by the second driving mechanism to move transversely.

[0006] As a preferred embodiment of the present utility model, a first connection block is fixedly installed at the upper end of the needle bed, a second connection block is fixedly installed at the lower end of the output shaft, the first connection block is connected to the second connection block, and the tufting device further includes a groove plate mounting seat. The groove plate is fixedly installed on the groove plate mounting seat, and the groove plate mounting seat is fixedly connected to the first connection block.

[0007] As a preferred embodiment of the present utility model, the first connection block is a T-shaped connection block with a T-shaped cross-section, the second connection block is a half, the groove plate mounting seat is angle-shaped, the first connection block is fixedly connected to the second connection block by bolts, and the groove plate mounting seat is fixedly connected to the first connection block by bolts.

[0008] As a preferred embodiment of the present utility model, the first connection block is a guide rail, the second connection block is a slider, the groove plate mounting seat is angle-shaped, the first connection block is slidably connected to the second connection block, and the groove plate mounting seat is fixedly connected to the first connection block by bolts.

[0009] As a preferred embodiment of the present utility model, the first connection block and the second connection block are slidably connected through a dovetail groove, a triangular groove, a trapezoidal groove, or a rectangular groove structure.

[0010] As a preferred embodiment of the present utility model, the first driving mechanism includes a motor. The needle bed movement mechanism further includes a rotating shaft, an eccentric wheel, and an eccentric sleeve connecting rod. The rotating shaft is rotatably installed on the side plate of the fuel tank of the lawn mower and is driven to rotate by the motor. The eccentric wheel is fixedly installed on the rotating shaft. The upper end of the eccentric sleeve connecting rod is sleeved on the eccentric wheel, and the lower end of the eccentric sleeve connecting rod is rotatably connected to the upper end of the output shaft. The output shaft is in sliding fit with the bottom plate of the fuel tank of the lawn mower.

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

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

[0013] As a preferred embodiment of the present utility model, the cross-section of the groove plate is concave-shaped. The tufting device further includes a plurality of pressing blocks. The pressing blocks are installed at intervals along the length direction of the groove plate on the opening side of the groove. The transverse moving strip is in clearance fit with the pressing blocks and the groove.

[0014] After adopting the above structure, the present utility model has the following beneficial effects:

[0015] The utility model is provided with a groove plate, a transverse movement strip plate and a second driving mechanism. The groove plate is strip-shaped and has a horizontally arranged top plate and a bottom plate. A groove is arranged 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 vertically corresponding to each other. The transverse movement strip plate is strip-shaped and is provided with a third through hole along the length direction. The transverse movement strip plate is placed in the groove, and the third through hole is arranged vertically corresponding to the first through hole and the second through hole. The transverse movement strip plate is driven by the second driving mechanism to move transversely. During normal operation, the grass yarn is unwound from the yarn bobbin, passes through the first through hole on the top plate of the groove plate, the third through hole on the transverse movement strip plate and the second through hole on the bottom plate of the groove plate in sequence, and then enters the tufting needle to realize normal flocking weaving. When the machine stops or the needle bed temporarily stops moving for reasons such as changing workstations, the second driving mechanism drives the transverse movement strip plate to move transversely for a certain distance, so that the positions of the third through hole and the first through hole and the second through hole are misaligned, and the third through hole and the first through hole and the second through hole are no longer vertically corresponding. In this way, the grass yarn is locked by the fold angles between the first through hole and the third through hole and between the second through hole and the third through hole. At this time, the grass yarn can neither enter nor retreat, effectively preventing the grass yarn at the tufting needle from being loose and without tension, ensuring that the grass yarn at the tufting needle is in a working tension state. When the machine starts or the needle bed continues to work, the second driving mechanism drives the transverse movement strip plate to move transversely in the reverse direction by a corresponding distance, so that the transverse movement strip plate returns to its original initial position again, that is, the third through hole is vertically corresponding to the first through hole and the second through hole. The utility model enables the tension of the grass yarn to be in a controllable state, effectively avoiding that the flocking of the tufting needle or the cutting of the yarn by the cutter is not in place and inaccurate, preventing failures during flocking and cutting, and improving the quality of the lawn finished product.

[0016] The utility model installs a first connecting block at the upper end of the needle bed. The groove plate is installed on a groove plate mounting seat, and the groove plate mounting seat is fixedly connected with the first connecting block. During work, the groove plate moves together 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 lawn finished product is better.

[0017] The first connecting block and the second connecting block of the utility model can be fixedly connected or slidably connected. When the two are fixedly connected, single-color flocking can be realized. When the two are slidably connected, the needle bed can be driven to move transversely by a transverse movement driving mechanism, and double-color flocking can be realized. The utility model is applicable to a wide range of machine types.

[0018] The hole pitch between the first through holes, the hole pitch between the second through holes and the hole pitch between the third through holes of the utility model are equal. Such a structure, on the one hand, makes the processing of the groove plate and the transverse movement strip plate more convenient and the manufacturing cost lower, and on the other hand, the grass yarn passes through the first, second and third through holes more smoothly.

[0019] The structure of the utility model is simple, and the processing and operation are very convenient. Description of the Drawings
