Description

Technical Field

[0001] The present application relates to the field of rubber scraper technology, and in particular to a rubber scraper for a polyurethane material sports track. Background Art

[0002] Polyurethane plastic track, also known as all-weather sports track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. It has the advantages of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. According to its construction structure and materials, the plastic track can be divided into prefabricated plastic track, full plastic track, mixed plastic track, composite plastic track, breathable plastic track, EPDM plastic track, etc. Among them, the prefabricated plastic track is convenient and quick to lay and is widely used.

[0003] During the construction of the prefabricated plastic track, the asphalt base layer of the track is first cleaned, and glue (adhesive) is applied to the base layer by a scraper or manually to form a bonding layer, and then the prefabricated polyurethane plastic roll is laid on the bonding layer.

[0004] A Chinese patent with announcement number CN111794060B discloses a glue application device and a glue application method, which includes a machine base, a moving device arranged on the machine base, a material storage device, a glue coating device, a conveying device and a swinging mechanism. The moving device is used to drive the glue application device to move, and the material storage device is used to store glue. The glue coating device includes a glue coating tube, and a plurality of glue outlet holes are arranged on the bottom surface of the glue coating tube. The plurality of glue outlet holes are arranged in a row or in multiple rows. The spacing between adjacent glue outlet holes is 3mm to 5mm, and the diameter of the glue outlet holes is 2mm to 4mm. The conveying device is respectively connected to the material storage chamber and the glue coating tube, and is used to convey the glue in the material storage chamber to the glue coating tube. The swinging mechanism is connected to the glue coating tube, and is used to drive the glue coating tube to swing back and forth, so that the glue forms a regular wavy texture on the base layer.

[0005] With regard to the above-mentioned related technologies, the inventors believe that the diameter of the glue outlet hole in the glue application equipment is 2mm to 4mm, which is relatively small. Since the glue itself is relatively viscous, the glue outlet hole may be blocked during the glue discharging process, reducing the amount of glue discharged, thereby making the bonding layer uneven, resulting in the runway being not flat enough after paving. Summary of the invention

[0006] In order to improve the problem that the glue outlet holes are easily clogged, resulting in an uneven bonding layer and an uneven track after paving, the present application provides a glue scraper for a polyurethane material sports track.

[0007] The present application provides a rubber scraper for a polyurethane sports track, which adopts the following technical solution:

[0008] A glue scraper for a polyurethane material sports track, comprising a mobile vehicle, a glue coating tube, a material storage device for storing glue, and a conveying device for conveying glue from the material storage device to the glue coating tube, wherein both the material storage device and the conveying device are arranged on the mobile vehicle, the glue coating tube is arranged on the mobile vehicle, the glue coating tube is provided with two glue discharge holes, a pair of clearing mechanisms for clearing the glue discharge holes are arranged in the glue coating tube, and a driving mechanism for driving the pair of clearing mechanisms is arranged on the mobile vehicle;

[0011] By adopting the above technical solution, the mobile vehicle moves on the base layer, and at the same time, the glue is transported from the storage device to the glue coating tube through the conveying device. The glue in the glue coating tube drips onto the base layer through the glue outlet hole, and then the glue is scraped flat by the scraper to form an adhesive layer. The driving mechanism drives the clearing mechanism to clear the glue outlet hole to reduce the possibility of clogging the glue outlet hole and reducing the discharge amount. This can reduce the possibility that the scraper cannot scrape the glue flat due to the reduction in the amount of glue on the base layer, forming an uneven adhesive layer, and making the runway not flat after paving.

[0012] By recycling the glue in the driving mechanism through the guide mechanism, the possibility of the glue solidifying after being left standing for a long time and affecting the operation of the driving mechanism can be reduced.

[0013] Optionally, the clearing mechanism includes a lifting rod and a plurality of clearing needles arranged on the lifting rod, the clearing needles are directly opposite to the top of the glue outlet hole, and the lifting rod is connected to the driving mechanism.

[0014] By adopting the above technical solution, the driving mechanism drives the clearing needle on one of the lifting rods to descend and insert it into the glue outlet hole to clear the glue outlet hole. At the same time, the driving mechanism drives the other lifting rod to rise, so that the clearing needle on the other lifting rod is pulled out of the glue outlet hole, so that the glue can drip onto the base layer. The two lifting rods are alternately descended under the action of the driving mechanism, so that the clearing needle clears the glue outlet hole, which can reduce the possibility of clogging the glue outlet hole and reducing the glue output.

[0019] By adopting the above technical solution, in the initial state, the clearing needle on one lifting rod is inserted into the glue outlet hole to clear the glue outlet hole, and the clearing needle on the other lifting rod is not inserted into the glue outlet hole, so that the glue can flow from this part of the glue outlet hole to the base layer. By cooperating with the driving component and the reset component, the transmission component can be driven to move, so that a pair of lifting rods are alternately lowered, and the clearing needle can clear the glue outlet hole, so as to reduce the possibility of clogging of the glue outlet hole and the possibility of affecting glue discharge due to clearing of the glue outlet hole.

[0026] The driving assembly drives the transmission gear to rotate, and the transmission gear drives the winding roller to rotate, so that the pull rope is reeled in, and the second connection block is lowered and the first connection block is raised. When the clearing needle on the lifting rod connected to the second connection block has cleared the blockage, the reset assembly drives the first connection block and the second connection block to reset, and the cycle is repeated to clear all the glue outlet holes.

[0027] Optionally, the driving assembly includes a first rotating shaft, a clearing drive motor for driving the first rotating shaft to rotate, and a pair of incomplete gears arranged on the first rotating shaft, the clearing drive motor is arranged on the mounting tube, the first rotating shaft is rotatably connected to the mounting tube, and the pair of incomplete gears are meshed with the transmission gear in a one-to-one correspondence.

The glue collecting box is arranged on the frame, the glue guiding pipe is connected to the mounting pipe, and the glue return pipe is connected to the material storage device.

[0032] By adopting the above technical solution, the glue flows into the installation tube through the first sliding hole, and the glue flows into the glue collection box under the action of gravity for collection, and then the glue in the glue collection box is returned to the storage device through the glue return pump. On the one hand, the recycled glue can be used again, saving glue, and on the other hand, it can also reduce the possibility of the glue solidifying after being stationary for a long time in the installation tube and affecting the operation of the driving mechanism.

[0038] Optionally, rubber rings are provided on the hole walls of the first sliding hole and the second sliding hole, and the lifting rod is in contact with the rubber rings.

[0039] By adopting the above technical solution, the size of the first sliding hole and the second sliding hole can be reduced by the rubber ring, thereby reducing the amount of glue flowing into the mounting tube, and further reducing the possibility of the glue contacting the transmission component and affecting the operation of the driving mechanism.

[0050] The following is combined with Figure 1-6This application is described in further detail.

[0051] The present application embodiment discloses a polyurethane material sports track scraper. Figure 1-Figure 4 The polyurethane material sports track glue scraper comprises a mobile vehicle 1, a storage device 2, a conveying device 3, a glue coating tube 5, a scraper 4, an adjustment mechanism 9, a driving mechanism 7 and a pair of clearing mechanisms 6. Two glue discharge holes 51 are provided on the bottom wall of the glue coating tube 5. The storage device 2 is installed on the mobile vehicle 1 for storing glue, one end of the conveying device 3 is connected to the discharging device, and the other end of the conveying device 3 is connected to the glue coating tube 5 for conveying the glue in the storage device 2 to the glue coating tube 5.

[0052] Reference Figure 3 , Figure 4 and Figure 5 The driving mechanism 7 includes a driving assembly 71, a pair of mounting tubes 74, a transmission assembly 72 and a reset assembly 73. The glue coating tube 5 is located between the pair of mounting tubes 74 and is fixedly connected to the mounting tubes 74. The mounting tubes 74 are fixed on the mobile vehicle 1. The clearing mechanism 6 is located in the glue coating tube 5 and is used to clear the glue outlet hole 51. The transmission assembly 72 is installed in the mounting tube 74 and is used to drive the clearing mechanism 6. The driving assembly 71 is installed on the mounting tube 74 and is used to drive the transmission assembly 72. The reset assembly 73 is used to drive the clearing mechanism 6 to reset.

[0053] Reference Figure 1 and Figure 5 A frame 11 is fixed on the mobile vehicle 1, and the scraper 4 is fixed on the adjusting component. The adjusting component is installed on the frame 11 to drive the scraper 4 to rise and fall to adjust the distance between the scraper 4 and the base layer, so that the scraper 4 can scrape out adhesive layers of different thicknesses, and has a wider range of use.

[0054] During the gluing process, the mobile vehicle 1 moves on the base layer, and at the same time, the glue is conveyed from the storage device 2 to the glue coating tube 5 through the conveying device 3. The glue in the glue coating tube 5 drips onto the base layer through the glue outlet hole 51, and then the glue is scraped flat by the scraper 4 to form an adhesive layer. The driving component 71 and the reset component 73 cooperate to drive the transmission component 72 to move, so that a pair of lifting mechanisms alternately clear the glue outlet hole 51, thereby reducing the possibility of clogging the glue outlet hole 51, and further reducing the possibility that the scraper 4 cannot scrape the glue flat due to the reduction of the amount of glue on the base layer, forming an uneven adhesive layer, and making the runway not flat after paving.

[0055] Reference Figure 1 and Figure 2The material storage device 2 includes a housing 21, a feed pipe 23 fixed on the top of the housing 21, a guide hopper 22 fixed in the housing 21, and a stirring mechanism 24 installed on the housing 21. The staff can introduce glue into the housing 21 through the feed pipe 23. The stirring mechanism 24 includes a stirring drive motor 241, a stirring rod 242, and a plurality of stirring blades 243 fixed on the stirring rod 242. The stirring rod 242 is located above the guide hopper 22 and is rotatably connected in the housing 21. The stirring drive motor 241 is installed on the outer wall of the housing 21, and the output shaft of the stirring drive motor 241 is coaxially connected with the stirring rod 242. The stirring drive motor 241 drives the stirring rod 242 to rotate, so that the stirring blades 243 stir the glue, so that the various raw material components in the glue are evenly mixed during the gluing process, thereby improving the bonding effect.

[0056] Reference Figure 2 and Figure 3 The conveying device 3 includes a conveying pipe 31, a conveying pump 32 installed on the conveying pipe 31, and a conveying valve 33. One end of the conveying pipe 31 is connected to the bottom wall of the guide hopper 22, and the other end of the conveying pipe 31 is connected to the top wall of the glue coating tube 5. By opening the conveying valve 33 and starting the conveying pump 32, the glue in the shell 21 can be conveyed to the glue coating tube 5.

[0057] Reference Figure 3 and Figure 4 The clearing mechanism 6 includes a lifting rod 61 and a plurality of clearing needles 62 fixed on the lifting rod 61. The clearing needles 62 are directly above the glue outlet holes 51. In the initial state, the clearing needle 62 on one lifting rod 61 is inserted into the glue outlet hole 51 to clear the glue outlet hole 51, and the clearing needle 62 on the other lifting rod 61 is not inserted into the glue outlet hole 51, so that the glue can flow from this part of the glue outlet hole 51 to the base layer. In this embodiment, by setting the pressure of the delivery pump 32, the amount of glue flowing out of the glue outlet hole 51 can meet the amount of glue required for bonding.

[0058] Reference Figure 3 and Figure 4, a partition 10 is fixed in each of the pair of mounting tubes 74, and the partition 10 is arranged perpendicular to the base layer. The transmission assembly 72 and the reset assembly 73 are both located on the side of the partition 10 in the mounting tube 74 that faces away from the glue coating tube 5. The mounting tube 74 and the glue coating tube 5 are provided with a plurality of first sliding holes 52 for the lifting rod 61 to slide with, and the partition 10 is provided with a pair of second sliding holes 101 for the lifting rod 61 to slide with, and the hole walls of the first sliding holes 52 and the second sliding holes 101 are provided with rubber rings 12, and the lifting rod 61 passes through the first sliding holes 52 and the second sliding holes 101 in sequence to be fixedly connected with the driving assembly 71, and the lifting rod 61 fits the rubber ring 12. The partition 10 can reduce the possibility that the glue flows out through the first sliding hole 52 and directly flows onto the transmission assembly 72 and the reset assembly 73. The rubber ring 12 made of rubber material can reduce the size of the first sliding hole 52 and the second sliding hole 101, thereby further reducing the possibility that the glue contacts the transmission assembly 72 and the reset assembly 73 and affects the movement of the transmission assembly 72 and the reset assembly 73.

[0059] Reference Figure 3 , Figure 4 and Figure 5 In addition, a flow guide mechanism 8 is fixed on the frame 11, and the flow guide mechanism 8 includes a glue collection box 81, a glue guide tube 82, a glue return tube 83 and a glue return pump 84 installed on the glue return tube 83. The glue collection box 81 is fixed on the frame 11, and one end of the glue guide tube 82 is connected to the bottom wall of the mounting tube 74 located between the partition 10 and the glue coating tube 5, and the other end of the glue guide tube 82 is connected to the top wall of the glue collection box 81. Under the action of its own gravity, the glue flows from the mounting tube 74 into the glue collection box 81. One end of the glue return pipe 83 is connected to the side wall of the glue collection box 81, and the other end of the glue return pipe 83 is connected to the feed pipe 23. The glue return pump 84 is installed on the shell 21. The glue return pump 84 is started regularly to return the glue in the glue collection box 81 to the shell 21 for continued use to save glue. It can also reduce the storage of glue in the installation tube 74, and finally flow from the second sliding hole 101 to the side of the partition 10 facing away from the glue coating pipe 5. After standing for a long time, it solidifies and affects the possibility of the transmission component 72 and the reset component 73 to move.

[0060] Reference Figure 3 and Figure 4The transmission assembly 72 includes a rotating rod 728, a fixed pulley 721, a winding roller 723, a pull rope 722, a first connecting block 726, a second connecting block 727, a transmission shaft 724, and a transmission gear 725 located outside the mounting tube 74. The transmission shaft 724 is rotatably connected to the side wall of the mounting tube 74, and one end of the transmission shaft 724 is located outside the mounting tube 74, and the other end of the transmission shaft 724 is located inside the mounting tube 74. The transmission gear 725 and the winding roller 723 are both coaxially connected to the transmission shaft 724. One end of the rotating rod 728 is rotatably connected to the side wall of the mounting tube 74, and the other end of the rotating rod 728 is rotatably connected to the partition 10. The fixed pulley 721 is coaxially connected to the rotating rod 728, and the fixed pulley 721 is located above the winding roller 723.

[0061] The pull rope 722 is wound on the winding roller 723, one end of the pull rope 722 is fixed on the winding roller 723, and the other end of the pull rope 722 is overlapped on the fixed pulley 721. In this embodiment, the pull rope 722 is a steel wire rope. The first connecting block 726 and the second connecting block 727 are both fixed on the pull rope 722, and the fixed pulley 721 is located between the first connecting block 726 and the second connecting block 727. One of the lifting rods 61 is connected to a pair of first connecting blocks 726 at the same time, and the other lifting rod 61 is connected to a pair of second connecting blocks 727 at the same time. In the initial state, the clearing needle 62 on the lifting rod 61 connected to the first connecting block 726 is inserted into the glue outlet hole 51, and the clearing needle 62 on the lifting rod 61 connected to the second connecting block 727 is not inserted into the glue outlet hole 51. Under the steering action of the fixed pulley 721, when the first connecting block 726 rises, the second connecting block 727 descends, and when the first connecting block 726 descends, the second connecting block 727 rises, so that the pair of lifting rods 61 can drive the clearing needles 62 to descend alternately, without affecting the glue discharge while clearing the blockage.

[0062] Reference Figure 4 and Figure 5 The driving assembly 71 includes a first rotating shaft 711, a clearing driving motor 712, and a pair of incomplete gears 713 coaxially connected to the first rotating shaft 711. The clearing driving motor 712 is mounted on the outer wall of the mounting tube 74. The first rotating shaft 711 is simultaneously rotatably connected to the pair of mounting tubes 74. The incomplete gears 713 mesh with the transmission gears 725 in a one-to-one correspondence. The clearing driving motor 712 can simultaneously drive the pair of incomplete gears 713 to rotate through the first rotating shaft 711, thereby driving the pair of transmission shafts 724 to rotate simultaneously, and then driving the winding roller 723 to simultaneously reel in the pull rope 722, thereby reducing the possibility of the lifting rod 61 being skewed.

[0063] Reference Figure 3 and Figure 4The reset assembly 73 includes a reset spring 731 and a top plate 732. The top plate 732 is fixed to the inner wall of the mounting tube 74 and is located between the fixed pulley 721 and the first connecting block 726. The pull rope 722 slides through the top plate 732. The reset spring 731 is sleeved on the pull rope 722. One end of the reset spring 731 is fixed to the top plate 732, and the other end of the reset spring 731 is fixed to the first connecting block 726.

[0064] During the construction process, the unblocking drive motor 712 is started to drive the first rotating shaft 711 to rotate, so that the incomplete gear 713 rotates. When the incomplete gear 713 is meshed with the transmission gear 725, the winding roller 723 is driven to rotate, and the pull rope 722 is wound up, so that the second connecting block 727 descends and the first connecting block 726 rises. At the same time, the first connecting block 726 rises to compress the reset spring 731, so that the reset spring 731 stores energy. At this time, the lifting rod 61 connected to the second connecting block 727 drives the unblocking needle 62 to descend, and unblocks one of the discharge holes 51. When the incomplete gear 713 is not meshed with the transmission gear 725, under the elastic force of the reset spring 731, the first connecting block 726 is driven to descend, and the second connecting block 727 is raised. At this time, the lifting rod 61 connected to the first connecting block 726 drives the unblocking needle 62 to descend, and unblocks the other discharge hole 51. In this way, all the glue outlet holes 51 can be cleared and blocked, so that the glue can drip from the glue outlet holes 51 more smoothly onto the base layer, and a more uniform bonding layer is formed after being scraped by the scraper 4, so that the runway is smoother after paving.

[0065] Reference Figure 1 and Figure 6 The adjusting mechanism 9 includes an adjusting driving motor 92, a second rotating shaft 91, a pair of adjusting gears 93 coaxially connected to the second rotating shaft 91, and a pair of racks 94 slidably arranged on the frame 11. A dovetail block is fixed on the rack 94. A dovetail groove for the dovetail block to slide with is arranged on the frame 11 in a direction perpendicular to the base layer. The dovetail block is placed in the dovetail groove. The dovetail block cooperates with the dovetail groove so that the rack 94 can slide more stably. The scraper 4 is located between the pair of racks 94 and is fixedly connected to the rack 94. The adjusting driving motor 92 is installed on the frame 11. One end of the second rotating shaft 91 is coaxially connected to the output shaft of the adjusting driving motor 92. The adjusting gears 93 mesh with the racks 94 one by one. The adjusting driving motor 92 drives the pair of adjusting gears 93 to rotate. The rotation of the adjusting gears 93 can drive the racks 94 to rise and fall, thereby adjusting the distance between the scraper 4 and the base layer, so that the scraper 4 can scrape out adhesive layers of different thicknesses, and has a wider range of uses.

[0066] The implementation principle of a glue scraper for a polyurethane material sports track in an embodiment of the present application is as follows: during the gluing process, the mobile vehicle 1 moves on the base layer, and at the same time, the delivery pump 32 and the delivery valve 33 are started to transport the glue from the shell 21 to the glue coating tube 5. The glue in the glue coating tube 5 drips onto the base layer through one of the glue discharge holes 51, and then the glue is scraped flat by the scraper 4 to form an adhesive layer.

[0067] At the same time, the unblocking driving motor 712 is started to drive the first rotating shaft 711 to rotate, so that the incomplete gear 713 rotates. When the incomplete gear 713 meshes with the transmission gear 725, the winding roller 723 is driven to rotate, and the pull rope 722 is wound up, so that the second connecting block 727 descends and the first connecting block 726 ascends. At the same time, the first connecting block 726 ascends and compresses the reset spring 731, so that the reset spring 731 stores energy. At this time, the lifting rod 61 connected to the second connecting block 727 drives the unblocking needle 62 to descend, and unblocks one of the discharge holes 51.

[0068] When the incomplete gear 713 is not meshed with the transmission gear 725, the first connection block 726 is driven down and the second connection block 727 is raised under the elastic force of the reset spring 731. At this time, the lifting rod 61 connected to the first connection block 726 drives the clearing needle 62 to descend and clear the blockage of another glue discharge hole 51. In this way, all the glue discharge holes 51 can be cleared, so that the glue can drip more smoothly from the glue discharge hole 51 onto the base layer, and a more uniform bonding layer is formed after being scraped by the scraper 4, so that the runway is more flat after paving.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
