Description

Technical Field

[0001] The utility model relates to the technical field of dust sticky pads, in particular to a glue coating device. Background Art

[0002] Sticky mats, also known as sticky floor glue, are mainly suitable for being placed at the entrance of clean spaces and in buffer zones. They can effectively remove dust from soles and wheels, minimizing the impact of dust on the quality of the clean environment, thereby achieving a simple dust removal effect and solving the problem that other floor mats cannot completely remove dust and cannot ensure that dust does not spread.

[0003] At present, the amount of glue applied on the sticky mat is generally sensed by a sensor, which transmits a signal to one side of the solenoid valve, and the solenoid valve controls the amount of glue output. However, in actual applications, due to high temperature or light problems, the sensor's sensing is not stable enough and affects the glue output. That is, the existing glue application equipment has a relatively complex structure and the glue output may be unstable. Utility Model Content

[0029] Reference Figures 1 to 3 , the utility model provides a glue coating device 100.

[0030] The outer casing 10 of the glue coating device 100 of the utility model is formed with a glue coating chamber 10a and an inlet 10b and an outlet connected to the glue coating chamber 10a; the docking station 20 is arranged in the glue coating chamber 10a, the fixed bracket 31 of the glue coating assembly 30 is installed in the glue coating chamber 10a, and is located above the docking station 20, the glue coating roller 32 and the glue leveling roller 33 are rotatably connected along the fixed bracket 31, and are arranged at intervals along the conveying direction of the docking station 20, the glue storage groove 41 of the glue injection assembly is installed on the fixed bracket 31, and is provided with a glue outlet corresponding to the glue coating roller 32, the sealing member 42 is connected to the glue storage groove 41, the linkage member 43 is slidably connected to the fixed bracket 31, and is located above the docking station 20, and the sticky pad can push the linkage member 43 upward to drive the sealing member 42 to open the glue outlet.

[0031] In the present application, in the initial state, the sealing member 42 blocks the glue outlet. When the docking station 20 transfers the sticky dust pad to be coated with glue from the feed port 10b to the glue applying chamber 10a and is located on one side of the glue applying assembly 30, the sticky dust pad pushes the linkage member 43 upward, and the linkage member 43 drives the sealing member 42 to move relative to the glue storage groove 41. The sealing member 42 opens the glue outlet, so that the glue in the glue storage groove 41 continues to flow from the glue outlet to the surface of the glue applying roller 32, and the sticky dust pad is transferred to the bottom of the glue applying roller 32. The glue applying roller 32 is attached to the surface of the sticky dust pad and glues it. After completion, the linkage member 43 moves downward, the sealing member 42 is reset, and the glue outlet is re-blocked. The sticky dust pad is transferred to the side of the glue roller 33 under the transfer of the docking station 20, and flows out from the discharge port, and so on. From the above process, it can be seen that the utility model can simplify the structure of the glue coating device 100 to the greatest extent by adopting the linkage member 43 and the sealing member 42 to cooperate with each other. The linkage member 43 and the sealing member 42 open or close the glue outlet under the action of the sticky pad, so that the glue output of the glue injection component is relatively stable, which greatly avoids the waste of glue and improves the effect of gluing the sticky pad.

[0032] In one embodiment of the utility model, the sealing member 42 includes a sealing plate 421 and a linkage rod 422 connected to each other. Specifically, the sealing plate 421 is rotatably connected to the open end of the glue outlet through a connecting shaft, and the linkage rod 422 is fixedly connected to the mounting shaft 311 and extends along the direction of the sticky mat transmission. The linkage rod 422 is transmission-connected with the linkage member 43, wherein the linkage member 43 includes a top plate 431 and a sliding roller 432 disposed at the bottom of the top plate 431, the sliding roller 432 can rotate relative to the top plate 431, and the lowest plane of the sliding roller 432 in the vertical direction should be lower than the lowest plane of the glue roller 32, the opposite sides of the fixed bracket 31 are provided with mounting shafts 311, the mounting shafts 311 extend along the height direction of the fixed bracket 31, the opposite sides of the top plate 431 are provided with mounting holes penetrating the upper and lower surfaces thereof, and the mounting shafts 311 are penetrated through the mounting holes to slide the top plate 431 and the fixed bracket 31 in connection. One end of the linkage rod 422 is connected to the mounting shaft 311 of the sealing plate 421 , and the other end is overlapped on the top of the top plate 431 .

[0033] In actual work, when the docking station 20 transfers the sticky pad to be coated with glue to one side of the glue spreading assembly 30, the force of the sticky pad drives the sliding roller 432 to roll, and then lifts the top plate 431, and the top plate 431 drives the linkage rod 422 to swing upward, and the sealing plate 421 located on the other side of the mounting shaft 311 swings downward, and the glue outlet is opened, so that the glue in the glue storage tank 41 continues to flow from the glue outlet to the surface of the glue spreading roller 32, and the glue spreading roller 32 is attached to the surface of the sticky pad to apply glue to it. After completion, the sticky pad is separated from the sliding roller 432, and under the action of gravity, the top plate 431 moves downward, and the sealing plate 421 re-blocks the glue outlet. In this application, the top plate 431 is used as the power source for rotating the sealing plate 421, and the power for the up and down movement of the top plate 431 comes from the sticky pad, so the time point of opening and closing the glue outlet can be determined according to the working state, so that the effect of opening or closing the glue outlet in time can be better achieved.

[0034] Furthermore, the sealing plate 421 also includes a torsion spring (not shown), which is arranged between the sealing plate 421 and the glue storage tank 41. In the present application, the elastic force provided by the torsion spring is utilized to make the sealing plate 421 re-block the glue outlet. This can avoid the situation where the sealing plate 421 still opens the glue outlet after the sticky mat flows out, thereby avoiding glue waste.

[0035] Furthermore, the linkage member 43 also includes a spring 433, which is sleeved on the mounting shaft 311. The spring 433 elastically presses against the fixed bracket 31 and the top plate 431, so as to push the top plate 431 upward again after the sticky pad is detached from under the top plate 431, thereby avoiding the top plate 431 from getting stuck and continuously opening the glue outlet.

[0036] In one embodiment of the present invention, the glue spreading assembly 30 further includes a centrifugal fan 34, which is disposed in the glue spreading chamber 10a. The centrifugal fan 34 is used to accelerate the air flow in the glue spreading chamber 10a to accelerate the formation of glue on the surface of the sticky mat.

[0037] Furthermore, the outer housing 10 further comprises a barrier curtain (not shown), which is arranged at the inlet 10b and the outlet 10b. The barrier curtain is used to maintain the temperature balance in the glue applying chamber 10a to the greatest extent.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
