DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9The present invention provides a technical solution: an artificial turf punching machine, comprising a frame 1, a mounting plate 2 is fixedly connected to the left side of the frame 1, a threaded rod 3 is fixedly connected to the right side of the mounting plate 2, a punching assembly 4 is arranged outside the threaded rod 3, the punching assembly 4 comprises a punching head 41 arranged outside the threaded rod 3, the inner left side of the punching head 41 is threadedly connected to the threaded rod 3, an isolation cover 42 is fixedly connected to the inner part of the punching head 41, a cavity 49 is formed between the isolation cover 42 and the inner part of the punching head 41, a sliding rod 16 is slidably connected to the inner part of the threaded rod 3, an electric heating rod 44 is fixedly installed on the right side of the sliding rod 16, the heating end of the electric heating rod 44 passes through the isolation cover 42 and extends into the inner part of the cavity 49, the outer wall of the punching head 41 is on the left side A bearing 43 is installed on the side, and the bearing 43 is a mature existing technology. The punching head 41 is fixedly connected to the inner ring of the bearing 43, and a mounting ring 45 is fixedly installed on the left side of the outer ring of the bearing 43. A moving plate 46 is fixedly connected to the left side of the mounting ring 45. The front and rear ends of the moving plate 46 are slidably connected to the inner side of the frame 1, and an electric telescopic rod 47 for driving the moving plate 46 to move left and right is provided on the left side of the moving plate 46. A punching groove 7 is provided near the punching head 41 of the frame 1, and one end of the electric telescopic rod 47 away from the moving plate 46 is fixedly plugged with the mounting plate 2, and the output shaft of the electric telescopic rod 47 is fixedly connected to the moving plate 46. A magnetic fluid seal 48 is installed between the electric heating rod 44 and the isolation cover 42, and the right side of the punching head 41 is tilted.

[0033] By adopting the above technical solution, the device needs to be used overhead, and the device can be installed overhead through an external hardware bracket to ensure that the bottom of the device is away from the ground. When in use, the artificial turf base layer that needs to be punched passes through the right side of the punching head 41 and the inner side of the frame 1, and the right side of the base layer fits the inner side of the frame 1. The base layer can be towed by an external traction device to move the base layer, thereby facilitating punching holes in different areas of the base layer.

[0034] The interior of the cavity 49 is filled with heat carrier oil. It should be noted that the interior of the sliding rod 16 is provided with an electric wire for energizing the electric heating rod 44, and the electric wire is electrically connected to an external power supply. In the preparation stage for punching, the electric heating rod 44 is energized to heat the heat carrier oil inside the cavity 49, thereby heating the surface portion of the punching head 41 through the heat carrier oil. The punching head 41 can be heated for punching. When the rubber material is heated, the activity of its molecular chains is enhanced and it becomes easier to deform, which can reduce the pressure required for punching. When punching, the elastic rebound of the softened rubber is significantly reduced when it is subjected to the punching pressure of the punching head 41, which helps to maintain the hole size after punching.

[0035] When punching, the output shaft of the electric telescopic rod 47 is extended to make the movable plate 46 move to the right, so that the mounting ring 45 moves to the right with the bearing 43 and the punching head 41. It should be noted that the threaded rod 3 has a larger thread pitch, which is similar to the screw part of a hand-pushed flying saucer. The larger thread pitch can reduce the contact area, thereby reducing the friction during movement, and the internal threaded connection between the threaded rod 3 and the punching head 41 is similar to the threaded connection of a hand-pushed flying saucer. Therefore, when the mounting ring 45 moves to the right with the bearing 43 and the punching head 41, the punching head 41 can be moved to the right under the action of the threaded connection. The rotating plate 46 will not affect the rotation of the punching head 41 under the action of the bearing 43, so that the punching head 41 can rotate while punching. The rotating punching head 41 can make the punching process more gradual, avoiding material tearing caused by direct impact, thereby ensuring the smoothness of the hole mouth, which is beneficial to improving the punching effect, and avoiding the rebound of the torn part of the material after the punching is completed to block the punched drainage hole, ensuring that the punched drainage hole maintains the aperture size after the punching, thereby avoiding the situation of poor drainage during use, and avoiding affecting the use effect and service life of the artificial turf.

[0036] It should be noted that the magnetic fluid seal 48 is made of high temperature resistant material to avoid affecting the sealing performance of the magnetic fluid seal 48 when heating the heat carrier oil. This device uses heat carrier oil to heat the punching head 41. The magnetic fluid seal 48 ensures that the electric heating rod 44 will not affect the rotation of the punching head 41 and ensures the sealing performance of the heat carrier oil.

[0037] A small plate 410 is fixedly connected to the outer wall of the heating end of the electric heating rod 44 .

[0038] By adopting the above technical solution, when the mounting ring 45 moves relative to the threaded rod 3 with the bearing 43 and the punching head 41, the small plate 410 plays a mixing role on the heat carrier oil, so that the heat carrier oil is heated more evenly, which is beneficial to the uniform heating of the punching area of ​​the punching head 41. It should be noted that the small plate 410 is made of insulating and high-temperature resistant ceramic material.

[0039] An extrusion assembly 5 is provided on the outside of the punching head 41, and the extrusion assembly 5 includes an extrusion ring 51 provided on the outside of the punching head 41, and large tubes 52 are fixedly inserted at both front and rear ends of the left side of the extrusion ring 51, and the outer wall of the large tube 52 is slidably connected to the movable plate 46, and a fixing ring 53 is fixedly connected to the left side of the outer wall of the large tube 52, and a first spring 54 is fixedly connected between the fixing ring 53 and the movable plate 46, the interior of the mounting plate 2 is hollow, and an air intake pipe 10 is fixedly inserted on the left side of the mounting plate 2, and a small tube 55 is slidably connected to the inside of the large tube 52, and one end of the small tube 55 away from the large tube 52 is fixedly inserted to the mounting plate 2, and a plurality of air intake holes 11 are opened on the inner side of the extrusion ring 51.

[0040] By adopting the above technical solution, when the first spring 54 is normally stretched, the right side surface of the extrusion ring 51 is on the right side of the punching head 41. When punching, the right side of the extrusion ring 51 first contacts the base layer. As the moving plate 46 and the punching head 41 continue to move to the right, the large tube 52 slides with the moving plate 46, and the first spring 54 is compressed, so that the first spring 54 provides elastic force to the extrusion ring 51, so that the extrusion ring 51 cooperates with the frame 1 to extrude the surrounding part of the base layer where the punching area needs to be punched. By pre-extruding the punching area of ​​the base layer, the deformation and displacement of the material during punching can be reduced, thereby improving the accuracy of the punching and the accuracy of the position, thereby improving the punching effect.

[0041] The end of the suction pipe 10 away from the mounting plate 2 is connected to an external dust suction device. When in use, the external dust suction device is started, and the gas inside the extrusion ring 51 can be absorbed through the internal hollow setting of the mounting plate 2, the small tube 55 and the large tube 52, so that the extrusion ring 51 absorbs the generated smoke through the suction hole 11, thereby preventing the smoke generated when the heated punching head 41 punches holes from floating in the air, resulting in a poor production environment and affecting the health of the workers. The interior of the extrusion ring 51 is fixedly connected with a uniform ring 12, and a plurality of uniform holes 13 are opened on the ring side of the uniform ring 12. The plurality of uniform holes 13 and the plurality of suction holes 11 are staggered. The design of the uniform ring 12 and the uniform holes 13 facilitates uniform suction of the plurality of suction holes 11.

[0042] It should be noted that, since the extrusion ring 51 squeezes the surrounding part of the perforated area during punching, the extrusion ring 51 is close to the perforated area, so the multiple suction holes 11 are close to the perforated area, so that the effect of absorbing smoke is good.

[0043] A gas passage 14 is provided inside the frame 1 , and the gas passage 14 is communicated with the hollow space inside the mounting plate 2 . A plurality of circular holes 15 are provided near the punching grooves 7 on the frame 1 .

[0044] By adopting the above technical solution, since the gas channel 14 is connected to the hollow part inside the mounting plate 2, when the external dust suction equipment starts to suck air, the multiple circular holes 15 can also be used for suction, and the smoke can be absorbed in the area near the perforation on the other side of the base layer, thereby further improving the smoke absorption effect and preventing the absorbed harmful smoke from floating in the working environment.

[0045] The left front and rear ends of the extrusion ring 51 are both fixedly connected with scrapers 6 , and one end of the scraper 6 away from the extrusion ring 51 is in contact with the outer wall of the punching head 41 .

[0046] By adopting the above technical solution, after the drilling is completed, the mounting ring 45 moves to the left direction with the bearing 43 and the drilling head 41. Under the action of the threaded connection, the drilling head 41 rotates. During this process, the scraper 6 can scrape the outer wall of the drilling head 41 to avoid part of the rubber sticking to the surface of the drilling head 41, which will affect the cleanliness of the drilling head 41 on the one hand, and on the other hand, if the rubber stuck to the drilling head 41 is not cleaned in time, it may be carbonized at high temperature, which will release harmful gases.

[0047] The frame 1 is provided with a cooling assembly 8 near the punching groove 7, and the cooling assembly 8 includes a fixed cylinder 81 fixedly connected to the frame 1 near the punching groove 7, a moving tube 82 is slidably connected to the middle part of the fixed cylinder 81, a water spray cover 83 is fixedly inserted on the left side of the moving tube 82, and a plurality of water spray holes 84 are opened on the ring side of the water spray cover 83, a piston 85 is provided inside the fixed cylinder 81, and the outer wall of the piston 85 is in contact with the inner wall of the fixed cylinder 81, and a gas assembly 9 is provided outside the fixed cylinder 81, and the gas assembly 9 It includes an extrusion plate 91 fixedly connected to the bottom of the movable plate 46, a second spring 86 fixedly connected between the left side of the piston 85 and the right side of the inner wall of the fixed cylinder 81, a corrugated airbag 92 fixedly connected to the left side of the extrusion plate 91, an air guide tube 93 fixedly connected to the rear end of the ring side of the corrugated airbag 92, the air guide tube 93 is made of hose material near the corrugated airbag 92 to avoid affecting the movement of the corrugated airbag 92, a branch pipe 94 is fixedly plugged into the ring side of the fixed cylinder 81, and the end of the branch pipe 94 away from the fixed cylinder 81 is fixedly plugged into the air guide tube 93.

[0048] By adopting the above technical solution, when the drilling is completed, the output shaft of the electric telescopic rod 47 is contracted, so that the mounting ring 45 of the movable plate 46, the bearing 43 and the drilling head 41 are moved to the left direction until the left side of the corrugated airbag 92 contacts the mounting plate 2, and then the output shaft of the electric telescopic rod 47 continues to contract, so that the corrugated airbag 92 is squeezed and compressed, and the gas inside it enters the branch pipe 94 through the air guide pipe 93, and enters the inside of the fixed cylinder 81 from the branch pipe 94 and is in the right area of ​​the piston 85. Under the action of the gas pressure, the piston 85 is convenient to move to the left direction with the movable tube 82 and the water spray cover 83, so that the water spray cover 83 reaches the hole punched in the base layer. It should be noted that the right side of the movable tube 82 is connected to the external water injection pipe, and cold water can be injected through the external water injection equipment. The cold water is discharged from the water spray hole 84, which is convenient for quickly cooling the punched area to avoid deformation of the punched drainage holes due to lack of cooling, thereby avoiding affecting the aperture of the drainage holes and ensuring the drainage effect after lawn making. When the water spray is cooled, the output shaft of the electric telescopic rod 47 is slightly extended until the corrugated airbag 92 is not squeezed. At this time, under the elastic force of the second spring 86, the movable tube 82 and the water spray cover 83 are reset, and the water spray cover 83 leaves the hole punched in the base layer. The base layer can be towed by an external traction device to punch holes in other areas.

[0049] It should be noted that an O-ring can be installed at the right side of the fixed cylinder 81 where it contacts the moving tube 82 to ensure the sealing of the fixed cylinder 81 in the right area of ​​the piston 85, and a through hole is opened in the left area of ​​the fixed cylinder 81.

[0050] Working principle: When in use, the artificial turf base layer that needs to be punched passes through the right side of the punching head 41 and the inner side of the frame 1, and the right side of the base layer fits the inner side of the frame 1. The base layer can be pulled by an external traction device to move the base layer, so as to facilitate punching of different areas of the base layer. The interior of the sliding rod 16 is provided with a wire for energizing the electric heating rod 44, and the wire is electrically connected to an external power supply. In the preparation stage for punching, the electric heating rod 44 is energized to heat the heat carrier oil inside the cavity 49, so that the surface part of the punching head 41 is heated by the heat carrier oil, and the output shaft of the electric telescopic rod 47 is extended to make the movable plate 46 move to the right direction, so that the mounting ring 45 moves to the right direction with the bearing 43 and the punching head 41. When the installation When the ring 45 moves to the right with the bearing 43 and the punching head 41, the punching head 41 can rotate under the action of the threaded connection. Under the action of the bearing 43, the movable plate 46 will not affect the rotation of the punching head 41. In this way, the punching head 41 can rotate while punching when punching. The rotating punching head 41 can make the punching process more gradual and avoid material tearing caused by direct impact, thereby ensuring the smoothness of the hole mouth, which is beneficial to improving the punching effect and avoiding the partial rebound of the torn material after the punching is completed to block the punched drainage hole. When the mounting ring 45 moves relative to the threaded rod 3 with the bearing 43 and the punching head 41, the small plate 410 plays a mixing role on the heat carrier oil, so that the heat carrier oil is heated more evenly, which is beneficial to the uniform heating of the punching area of ​​the punching head 41.

[0051] When the first spring 54 is normally stretched, the right side surface of the extrusion ring 51 is on the right side of the punching head 41. When punching, the right side of the extrusion ring 51 first contacts the base layer. As the moving plate 46 and the punching head 41 continue to move to the right, the large tube 52 slides with the moving plate 46, and the first spring 54 is compressed, so that the first spring 54 provides elastic force to the extrusion ring 51, so that the extrusion ring 51 cooperates with the frame 1 to extrude the surrounding part of the base layer where the punching area needs to be punched. By pre-extruding the punching area of ​​the base layer, the deformation and displacement of the material during punching can be reduced, thereby improving the punching effect. The end of the suction duct 10 away from the mounting plate 2 is connected to an external dust suction device. When in use, the external dust suction device is started, and the gas inside the extrusion ring 51 can be absorbed through the internal hollow setting of the mounting plate 2, the small tube 55 and the large tube 52, so that the extrusion ring 51 absorbs the generated smoke through the suction hole 11, thereby preventing the smoke generated by the heated punching head 41 from floating in the air when punching, resulting in a poor production environment and affecting the health of the staff.

[0052] The output shaft of the electric telescopic rod 47 contracts, causing the corrugated airbag 92 to be squeezed and compressed, and the gas inside it enters the branch pipe 94 through the air guide pipe 93, and enters the interior of the fixed cylinder 81 from the branch pipe 94 and is in the right area of ​​the piston 85. Under the action of the gas pressure, the piston 85 is convenient for moving the moving tube 82 and the water spray hood 83 to move to the left direction, and the water spray hood 83 reaches the hole punched in the base layer. It should be noted that the right side of the moving tube 82 is connected to the external water injection pipe, and cold water can be injected through the external water injection equipment. The cold water is discharged from the water spray hole 84, which is convenient for quickly cooling the punching area.
