Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, and more specifically to a cutting device for artificial turf production. Background Art

[0002] Artificial turf was born in the United States in the last century. It is a non-living plastic chemical fiber product. Unlike natural turf, it does not consume fertilizers, water and other resources necessary for growth. It can meet the needs of high-intensity sports throughout the day, and it is easy to maintain, drains quickly, and has excellent field flatness.

[0003] In the existing artificial turf production, a braiding machine is used to continuously weave plastic ropes on a base plate, and then an automatic cutting bed is used to cut the top of the circular plastic rope to form independent artificial grass strands. Because a large amount of plastic rope debris is generated during cutting, the debris accumulates at the cutting blade position and affects the thorough cutting. In view of this, we propose a cutting device for artificial turf production. Utility Model Content

[0024] Example:

[0025] This embodiment provides a cutting device for artificial turf production, referring to Figure 1 , including a bottom frame 1 and a top frame 2, wherein the bottom frame 1 has legs and is installed overhead, the top frame 2 is arranged above the bottom frame 2 and is fixed by an external bracket. After installation, a feeding gap 3 is formed between the bottom frame 1 and the top frame 2, and the artificial turf passes through the feeding gap 3 and can be horizontally and continuously moved for cutting processing, that is, a rotary cutter 4 is installed on the top frame 2 in the middle of the feeding gap 3, and the rotary cutter 4 can work above the artificial turf to cut off the continuous grass strands on the artificial turf to form independent grass strands, and when working, the outer side of the rotary cutter 4 The lower cover is provided with an outer cover 8, and the lower part of the rotary cutter 4 extends out of the lower end of the outer cover 8, so that the grass silk below can be cut, and the cut debris will gather at the opening position of the outer cover 8. In order to reduce the interference of the debris on the cutting, a wind pass piece 5 is installed on the top frame 2. At the same time, the air inlet end of the wind pass piece 5 is connected with the internal space of the outer cover 8. During cutting, the wind pass piece 5 draws out the air inside the outer cover 8 to form a negative pressure, and the debris cut by the rotary cutter 4 is attracted into the outer cover 8, and finally sucked out of the outer cover 8 by the wind pass piece 5, thereby completing the timely drainage of the debris and avoiding interference with the normal operation of the rotary cutter 4.

[0026] Reference Figure 3The outer cover 8 includes a main shell 81, which adopts a cylindrical hollow structure, and the main shell 81 opens downward, and a suction port can be formed at the contact position between the rotary knife 4 and the grass silk. When the main shell 81 is in a negative pressure state, a suction part 82 is installed on the side wall of the main shell 81 near the feeding gap 3. The suction part 82 is designed to be close to the feeding gap 3, and the debris can be attracted into the suction part 82 in real time after shearing. Then, the main shell 81 is installed with an air outlet part 83 above the air suction part 82. The air outlet part 83 can provide airflow from above, and can blow down the excessively floating debris, so that the debris is concentrated around the suction part 82 for easy collection.

[0027] Reference Figure 3 The air passing part 5 includes a centrifugal pump 51. The centrifugal pump 51 adopts a vortex air pump. Even if there are debris in the air, it will not affect normal use. A suction pipe 52 is installed at the air inlet end of the centrifugal pump 51. The suction pipe 52 adopts a hard pipe. The suction pipe 52 is connected with the suction part 82, and the air and debris inside the suction part 82 can be sucked out and guided to the position of the centrifugal pump 51. A discharge pipe 53 is installed at the air outlet end of the centrifugal pump 51. The airflow generated by the operation of the centrifugal pump 51, the discharge pipe 53 is connected with the air outlet part 83, and the airflow will enter the air outlet part 83 through the discharge pipe 53. The air outlet part 83 can discharge air to blow down the debris inside the main shell 81 for auxiliary collection.

[0028] Reference Figure 2 A filter box 6 is installed in series between the suction pipe 52 and the suction part 82. The filter box 6 filters the airflow carrying debris and intercepts the debris. In this way, the airflow entering the air outlet part 83 through the discharge pipe 53 can be kept clean, and then the position of the rotary cutter 4 can be kept clean. A three-way pipe is installed on the suction pipe 52, and a suction frame 7 is installed at the lower end of the three-way pipe. When the artificial turf is transported, the artificial turf will be attracted downward by the suction frame 7 when it contacts the rotary cutter 4. The suction frame 7 is embedded and fixed on the base frame 1 directly below the rotary cutter 4. Continuous downward attraction can ensure that the artificial turf will not curl up when being cut, and ensure the uniformity of the grass silk after cutting.

[0029] Reference Figure 3 The attraction frame 7 includes a frame body 71. The frame body 71 adopts a hollow structure to form a rectangular attraction space, which can stably attract the artificial turf downward. The frame body 71 is fixedly connected to the base frame 1 to ensure the stability of the position of the frame body 71 and avoid shaking. A mesh plate 72 is installed at the top opening of the frame body 71. The mesh plate 72 can support the artificial turf and ensure the smooth passage of the artificial turf.

[0030] Reference Figure 2When the artificial turf is being transported, in order to ensure smooth transportation of the artificial turf, push rollers 9 are respectively installed at the edges of the bottom frame 1 and the top frame 2. The push rollers 9 are symmetrically arranged up and down, and there are four of them. Moreover, the push rollers 9 extend into the feeding gap 3, which can clamp and press the artificial turf to ensure smooth and stable transportation of the artificial turf, and further ensure that the artificial turf is in a taut state.

[0031] Reference Figure 4 The rotary cutter 4 includes two rotating shafts 41, which are arranged horizontally front and back to ensure that the distance to the base frame 1 is consistent. A mounting plate 42 is installed between the two rotating shafts 41, and a plurality of mounting plates 42 are provided. In addition, the mounting plates 42 are arranged in a circular array along the axis of the rotating shaft 41, and a cutter 44 is fixedly installed at one end of the mounting plates 42 away from each other. The mounting plates 42 rotate with the rotating shaft 41, which can drive the cutter 44 to rotate and cut the artificial turf below, and a cutting gap 43 is provided between the cutters 44, which can ensure that the cut debris is separated from the cutter 44 in time. It should be noted that the cutters 44 of different mounting plates 42 are arranged front and back to fully cover the top surface of the artificial turf to avoid incomplete cutting. The rotation of the plate-shaped mounting plate 42 can generate centrifugal wind force to blow the debris on the cutter 44 off and blow it to the suction part 82 installed at the lower part of the main shell 81, so as to realize the self-cleaning of the rotary cutter 4.

[0032] The rotating shaft 41 involved in the embodiment is connected to a motor, and the vortex air pump adopts an existing product produced by a manufacturer. Its supporting control system, solenoid valve, control switch and pipeline can also be provided by the manufacturer. In addition, the power supply module, circuit, electronic components and control module involved in the utility model are all existing technologies, which can be fully implemented by those skilled in the art without further elaboration.
