Description

Technical Field

[0001] The present invention relates to the technical field of glue spraying for plastic runways, and in particular to automatic glue spraying equipment for environmentally friendly plastic runways. Background Art

[0002] The plastic track is made of materials such as polyurethane rubber. It is elastic and beautiful, and has strong resistance to ultraviolet rays and aging. It is the main material for the floor of existing sports fields. When paving the plastic track, it is necessary to sprinkle particles on the surface glue to increase friction, and then spray the plastic track with glue to firmly fix the particles on the plastic track. The existing technology of glue spraying is mainly based on automatic glue spraying equipment. For example, an environmentally friendly plastic track glue spraying equipment with publication number CN212533616U includes a movable seat, and the upper and lower sides of the movable seat are penetrated by a slide groove, and the inner side of the slide groove is slidably connected with a slide seat, and one end of the movable seat is penetrated and plugged with a push rod, and one end of the push rod is fixed to the end of the slide seat, and a first push rod motor is fixed on one side of the movable seat, and the power output end of the first push rod motor is connected to the other end of the push rod through a connecting rod. The upper and lower sides of the slide seat are penetrated and fixed with a cannula, and the lower end of the cannula is fixed with a nozzle. The invention utilizes the cooperation between the sliding seat, the moving seat and the first push rod motor to control the stroke of the first push rod motor to control the glue spraying width of the nozzle on the plastic runway; the above technical solution can be used to adjust the glue spraying width, but the glue spraying width is adjusted by sliding several fixed nozzles to adjust the glue spraying range, and the number of nozzles cannot be adjusted to adjust the glue spraying range, which causes the glue sprayer to need to stop continuously to move the nozzle to cover the glue spraying width. Therefore, it is necessary to design a device that can adjust the glue spraying width and range by adding or removing nozzles, and the glue sprayer does not need to stop to move the nozzle to cover the glue spraying width, and the continuity is poor.

DETAILED DESCRIPTION

[0022] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0023] Example 1:

[0024] like Figures 1 to 8 As shown, the present invention provides an automatic glue spraying device for an environmentally friendly plastic runway, including a mobile body and a glue barrel mounted on the mobile body. The mobile body and glue barrel are prior art, and therefore their structures are not described in detail. The automatic glue spraying device also includes a telescopic frame 1 mounted on the mobile body. A primary spray bar 2 is fixedly mounted on the telescopic frame 1, and a secondary spray bar 3 is slidably mounted on the telescopic frame 1. The fixed primary spray bar 2 sprays glue within a fixed range, while the slidably adjustable secondary spray bar 3 adjusts the width and range of the glue spraying. A plurality of first-level nozzles 4 are connected to the first-level spray boom 2, and a plurality of second-level nozzles 5 are rotatably provided on both sides of the telescopic frame 1. The second-level nozzles 5 are rotated in sequence to the same horizontal line as the first-level spray boom 2 through the extension movement of the telescopic frame 1. The second-level spray boom 3 is connected to the second-level nozzle head 5 by the extension movement of the telescopic frame 1, so that the connecting pipe 6 on it is connected with the second-level nozzle head 5, so that the rotated and expanded second-level nozzle head 5 can be connected with the second-level spray boom 3 so that the liquid glue in the second-level spray boom 3 can enter the second-level nozzle head 5 for spraying; the first-level spray boom 2 and the second-level spray boom 3 are connected to the pump body on the glue barrel through a rubber hose, so that the liquid glue in the glue barrel is transported to the first-level spray boom 2 and the second-level spray boom 3 through the pump body.

[0025] Specifically, the telescopic frame 1 comprises a fixed beam 21, a limiting beam 22, an L-shaped beam 23, and a sliding beam 24. The fixed beam 21 is connected to the rear end of the mobile body. The middle portion of the limiting beam 22 is fixedly connected to the fixed beam 21. One end of the L-shaped beam 23 slides over the limiting beam 22, and the other end of the L-shaped beam 23 is connected to the sliding beam 24. One end of the secondary spray boom 3 is fixed to the L-shaped beam 23, allowing it to slide along with the L-shaped beam 23. The sliding beam 24 slides within the fixed beam 21. The limiting beam 22 is axially provided with a strip-shaped through-hole 25. The secondary spray head 5 is pivotally mounted on the L-shaped beam 23 via a swing arm 7. The swing arm 7 is provided with a rotating shaft 8, which is pivotally mounted on the L-shaped beam 23. A torsion spring 9 is sleeved on the rotating shaft 8, one end of which is connected to the end of the rotating shaft 8, and the other end of the torsion spring 9 is connected to the L-shaped beam 23. The rotating shaft 8 is provided with a protrusion 10, which, by entering the strip-shaped through-hole 25, rotates the rotating shaft 8, thereby tilting the secondary spray head 5 and storing it on the L-shaped beam 23. The fixed beam 21 is pivotally mounted on the mobile body via a hinge block 12. A push plate 13 is vertically provided on the hinge block 12, and an electric telescopic rod 14 is hingedly connected to the push plate 13. The end of the electric telescopic rod 14 is hingedly connected to the mobile body. The electric telescopic rod 14 adjusts the swing angle of the telescopic frame 1 via the electric telescopic rod 14, thereby adjusting the spraying angles of the primary and secondary spray heads 4 and 5.

[0026] Example 2:

[0027] like Figure 2 and Figure 3As shown, combined with the technical solution of Example 1, this embodiment further includes a rotating telescopic mechanism, which is provided on the fixed beam 21, and the sliding beam 24 is connected to the rotating telescopic mechanism, so that the rotating telescopic mechanism drives the sliding beam 24 to perform telescopic movement in the fixed beam 21 by rotation, thereby adjusting the width of the telescopic frame 1. The rotating telescopic mechanism includes a drive motor 31, a first bevel gear 32, a second bevel gear 33, and a rotating rod 34 with external threads at both ends. The drive motor 31 is provided in the middle of the fixed beam 21, the first bevel gear 32 is provided at the output end of the drive motor 31, and the second bevel gear 33 is provided on the rotating rod 34. The first bevel gear 32 and the second bevel gear 33 are engaged for transmission. The rotating rod 34 is rotatably provided in the fixed beam 21, and the end of the sliding beam 24 is threadedly connected to the rotating rod 34, so as to adjust the elongation of the sliding beam 24 in the fixed beam 21 by providing the rotating telescopic mechanism. Furthermore, the external threads at both ends of the rotating rod 34 rotate in opposite directions, so that when the rotating rod 34 rotates, the slider fixed to the end of the sliding beam 24 and connected to the external thread can push the sliding beams 24 on both sides of the fixed beam 21 to perform synchronous reverse relative movement, thereby realizing the telescopic frame 1 extending to both sides to adjust its glue spraying width; at the same time, under the action of the limiting beam 22, the L-shaped beam 23 can move together under the push of the sliding beam 24, so that the swing arm 7 rotatably connected thereto rotates to the same horizontal line as the first-level nozzle 4 under the action of the torsion spring 9, so as to adjust the number of nozzles of the automatic glue spraying equipment, thereby realizing the adjustment of the glue spraying width and range.

[0028] Example 3:

[0029] like Figure 1 and Figure 9As shown, combined with the technical solution of Example 2, in this embodiment, a plug-in port 51 is provided at the upper end of the secondary nozzle 5, a magnetic lock mechanism is provided at the end of the connecting pipe 6, an insert 41 is provided on the magnetic lock mechanism, and a conducting hole 42 is provided on the insert 41. The insert 41 is inserted into the plug-in port 51 to connect the secondary nozzle 5 with the secondary spray rod 3. The magnetic lock mechanism includes a sleeve 43, a permanent magnet 44, a spring 45 and an iron rod 46. The sleeve 43 is connected to the end of the connecting pipe 6 and is in communication with the connecting pipe 6; the iron rod 46 is arranged in the sleeve 43, and a wire 47 is wound around the iron rod 46; the permanent magnet 44 is slidably arranged in the sleeve 43, the inserting pipe 41 is connected to the permanent magnet 44, and the spring 45 is sleeved on the inserting pipe 41, so that the iron rod 46 is magnetized by energizing the wire 47 to attract the permanent magnet 44 to drive the inserting pipe 41 into the sleeve 43. When the end of the inserting pipe 41 is completely inserted into the sleeve 43, the conducting hole 42 on the inserting pipe 41 is disconnected from the connecting pipe 6. When the swing arm 7 drives the secondary nozzle 5 to rotate to the bottom of the sleeve 43, the wire 47 is de-energized, causing the spring 45 to drive the inserting pipe 41 downward, thereby causing the inserting pipe 41 to be plugged into the plug interface 51 on the secondary nozzle 5 to connect the connecting pipe 6 with the secondary nozzle 5. Furthermore, a sealing ring is provided at the end of the cannula 41. Furthermore, to enhance the insertion force of the cannula 41, the permanent magnet 44 can be a magnet that repels the iron rod 46. This allows the cannula 41 to extend out of the sleeve 43 when the wire 47 is energized, connecting the connecting tube 6 with the conducting hole 42. When the wire 47 is de-energized, the cannula 41 retracts into the sleeve 43 under the force of the spring 45, disconnecting the conducting hole 42 from the connecting tube 6. The device also includes a stopper sleeve 11, which is disposed on the fixed beam 21. The secondary spray boom 3 is slidably mounted on the stopper sleeve 11. The stopper sleeve 11 provides sliding support for the secondary spray boom 3.

[0030] Furthermore, an arc-shaped baffle protrudes from the end of the sleeve 43 to limit the secondary nozzle 5, so as to prevent the torsion spring 9 from causing the secondary nozzle 5 to flip too much.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the present technical solution.
