DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] See also Figures 1 to 5 The present invention provides a special marking device, which includes a device body 101, a plurality of cam gates and a plurality of first cylinders 102. The device body 101 is evenly provided with a plurality of cam gate structures. The top of the device body 101 is provided with a feed port 103, and the feed port 103 is connected to a feeding system of a marking vehicle.

[0023] Each of the cam gate structures is composed of a fixed bottom knife 104, a gate body 105 and an intermediate support seat. A plurality of the fixed bottom knives 104 are evenly installed at the bottom of the device body 101. The gate body 105 is installed on the rotating shaft of the device body 101. Each of the gate bodies 105 corresponds to a fixed bottom knife 104. The intermediate support seat 115 is installed inside the device body 101. The intermediate support seat 115 is used to auxiliary support the rotating shaft of the device body 101. The first cylinder 102 and the electromagnetic valve 106 are provided on the outer wall of the device body 101. The electromagnetic valve 106 controls the movement of the first cylinder 102. The output end of the first cylinder 102 is used to drive the gate body 105 to rotate.

[0024] In this embodiment, since a number of narrower cam gate structures are provided on the device body, each of the gate bodies 105 is driven to open and close by the first cylinder 102, and the telescopic movement of the first cylinder 102 is controlled by the solenoid valve 106. The action of the solenoid valve 106 is controlled by a signal sent by a controller. By writing different programs, the opening and closing of each of the gate bodies 105 are controlled. The feed port 103 of the device body is connected to the feeding system of the marking vehicle. The feeding system continuously delivers hot-melt paint with a certain pressure into the device. At this time, the paint will flow out of the opened gate body 105 to the ground. The entire device moves at a certain speed and opens and closes each of the gate bodies 105 according to a preset program. The paint flowing to the ground will form a preset pattern. The use of this technical solution can automatically and directly mark various special symbols.

[0025] Furthermore, a heat transfer oil heating channel 107 is provided inside each of the device bodies 101 , and a lubricating oil injection hole 108 is provided on each of the gate bodies 105 .

[0026] In this embodiment, the setting of the thermal oil heating channel 107 can ensure that the internal temperature of the hot melt coating and the entire device reaches a suitable temperature, and the setting of the lubricating oil injection hole 108 can ensure that the switching of each cam gate structure is flexible.

[0027] Furthermore, a hot melt paint reflux channel 109 is provided inside the feed port 103 .

[0028] In this embodiment, during the graphic drawing process, since the number of the gate bodies 105 opened at different times varies greatly, the required paint flow rates vary greatly, and the paint flow rate provided by the feed port 103 cannot be changed in a timely and large range to adapt to the flow rate required at different times, which will cause the thickness of the drawn graphics to vary greatly and fail to meet the standard requirements; for this reason, through the setting of the hot melt paint return channel 109, a constant large flow of paint is allowed to enter the marking device, a part of the paint flows through the gate body 105 to the ground to form a pattern, and the rest of the paint flows back to the paint pump suction port, thereby ensuring that the thickness of the drawn graphics is uniform, as shown in the attached figure. Figure 3 shown.

[0029] Furthermore, each of the cam gate structures is also provided with a slag discharge mechanism, which includes a second cylinder 110, a semicircular camshaft 111 and a limit screw 112. The second cylinder 110 is installed on the outer wall of the device body 101, the solenoid valve 106 controls the movement of the second cylinder 110, the semicircular camshaft 111 is installed inside the device body 101, the end of the limit screw 112 is in contact with the semicircular camshaft 111, the limit block of the limit screw 112 corresponds to the gate body 105, and the second cylinder 110 is used to drive the semicircular camshaft 111 to rotate.

[0030] In this embodiment, during the construction process, the gate body 105 is often blocked due to the large particles contained in the paint. At this time, the drawn figure will have missing cracks. Since the gate body 105 has a limited opening, it is unable to discharge the particles by itself, resulting in a stoppage of work. See attached Figure 4 When the gate body 105 is blocked, the second cylinder 110 starts to move, causing the semicircular camshaft 111 to rotate a certain angle, allowing the limit screw 112 to open a sufficiently large opening of the gate body 105 to discharge the particles, thereby quickly restoring the normal construction state.

[0031] Furthermore, two top covers 113 are provided on the top of the device body, and the two top covers 113 are respectively located on both sides of the feed port 103 .

[0032] In this embodiment, the detachable top cover 113 is provided to facilitate maintenance of the device body.

[0033] Furthermore, a plurality of paint flow distribution valves 114 are also provided on the device body, and each of the paint flow distribution valves 114 is located at the paint inlet of the corresponding cam gate structure.

[0034] In this embodiment, the paint flow distribution valve 114 drives the regulating valve core to move up and down by rotating the adjusting screw, thereby changing the flow area of ​​the paint inlet, so as to change the paint flow, make the paint pressure at each gate valve of the device more uniform, and make the thickness of the paint flowing out more uniform. The specific structure of the paint flow distribution valve 114 is shown in the attached Figure 5 .

[0035] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
