DETAILED DESCRIPTION

[0026] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0027] Figure 1 A schematic diagram showing the overall structure of the glue coating machine is shown. Figure 2 The figure shows a schematic diagram of the structure inside the shell of the gluing machine after the rear cover and one of the side panels are hidden. The gluing machine includes a shell and a gluing mechanism, a glue filling mechanism, and a paper rack arranged inside the shell. The shell is a structure with an open front side formed by a base plate 1 located at the bottom, two side panels 11, and an upper rear cover 12. The shell is made of ABS or PC material as a whole, the rear side of the rack is arranged at the open part of the shell, and the gluing mechanism is located at the rear side of the paper rack.

[0028] like Figure 3 and Figure 4 As shown, the glue coating mechanism specifically includes three parts: a glue brush 31, a linear reciprocating mechanism 2 for driving the glue brush 31 to move, and a track plate 3 that plays a guiding role. The two ends of the linear reciprocating mechanism 2 are respectively vertically connected to the two side plates 11 of the shell. In this embodiment, the linear reciprocating mechanism 2 is a linear motor. The slider of the linear motor slides along the guide rail to drive the glue brush 31 to achieve reciprocating motion. The glue brush 31 is connected to the slider of the linear motor through a rotating shaft, wherein the rotating shaft includes a tubular shaft 33 and a thin rotating shaft 32. The thin rotating shaft 32 has a glue brush 31 fixedly arranged at one end, and a limit pin 34 is provided at the other end in the radial direction. The tube shaft 33 is rotatably connected to the movable end (i.e., the slider 21) of the linear reciprocating mechanism 2. The inner wall of the tube shaft 33 near one end of the thin rotating shaft 32 is provided with a circumferentially arranged limit sheet 35. The thin rotating shaft 32 is inserted into the tube shaft 33. Through the cooperation of the limit sheet 35 and the limit pin 34, the thin rotating shaft 32 can rotate slightly along the tube shaft 33, thereby driving the glue brush 31 to achieve slight deflection. The slight deflection of the glue brush 31 when brushing glue can make the glue brush more even and reduce the generation of bubbles.

[0029] A connecting piece 37 is fixedly provided along the radial direction of one end of the tube shaft 33 away from the thin rotating shaft 32, and a guide shaft 36 is fixedly provided at the other end of the connecting piece 37. The guide shaft 36 is parallel to the rotating shaft, and the two are in opposite directions. The guide shaft 36, the connecting piece 37 and the rotating shaft form a shape similar to the letter Z. The track plate 3 is parallel to the linear reciprocating mechanism 2 and is located on the side away from the paper rack. A track groove is opened on the track plate 3 along its length direction. The track groove consists of a horizontal straight groove part and a vertical groove part connected to both ends of the straight groove. The guide shaft 36 is slidably set in the track groove.

[0030] Specific reference Figure 3 When the guide shaft 36 slides along the horizontal straight groove part, the rubber brush 31 is in a vertical state. When the linear reciprocating mechanism 2 is running, it drives the rubber brush 31 to reciprocate left and right. When the guide shaft 36 moves to the vertical groove part, the rubber brush 31 is driven by the rotating shaft to rotate 90 degrees. At this time, the rubber brush 31 is relatively in a horizontal state. When the rubber brush 31 is in a horizontal state, the glue replenishing mechanism starts to replenish glue to the bristles of the rubber brush 31.

[0031] Specific reference Figure 2-3 , at least one glue replenishing mechanism is provided, and in this embodiment, two glue replenishing mechanisms are provided, which are respectively fixed on the side plate 11. When the glue brush 31 approaches the side plate 11, the glue replenishing mechanism can replenish glue to it. The glue replenishing mechanism includes a glue containing pump 4 and a glue spraying nozzle 41. The glue containing pump 4 is fixed on the side plate 11. The glue containing pump 4 can spray glue along the glue spraying nozzle 41. The liquid outlet end of the glue spraying nozzle 41 is connected and communicated with the glue containing pump 4 through a glue outlet pipe 42. The liquid inlet end of the glue containing pump 4 is provided with a glue return pipe 43. The end of the glue return pipe 43 extends into the glue collecting bin 6. The glue collecting bin 6 is provided on the bottom plate 1 and is located directly below the glue brush 31. It is mainly used to collect the glue falling from the glue brush 31. The glue in the glue collecting bin 6 is sucked into the glue containing pump 4 through the glue return pipe 43 for replenishment. Through recycling, the waste of glue is reduced and the use cost is reduced. Through the implementation of this technology, the efficiency and quality of document adhesive coating in the office environment can be effectively improved, while reducing the cost investment of the enterprise and promoting the further development of office automation.

[0032] The limit switch 5 for controlling the glue containing pump 4 is also included. The limit switch 5 is arranged on the side plate 11. The limit switch 5 can be triggered when the glue brush 31 approaches the side plate 11. Specifically, the glue brush 31 will rotate 90 degrees when it approaches the side plate 11. During the rotation, the brush handle end will trigger the limit switch 5. The limit switch 5 adopts a photoelectric induction switch.

[0033] In addition, a glue filling port 9 is provided on the side plate 11 at a position corresponding to the glue collecting bin 6, and a side baffle 61 is provided on the bottom plate 1 to limit the glue collecting bin 6. The glue filling port 9 can be conveniently used to pull out the glue collecting bin 6 and add glue therein.

[0034] like Figure 5As shown, it should also be noted that the paper rack includes a placement table 7 and a limit block 13. The placement table 7 is used to place paper pieces. There are two limit blocks 13, which are symmetrically arranged on the left and right sides of the placement table 7, wherein sliding shafts 71 are respectively provided on both sides of the placement table 7, and a longitudinal straight groove 131 is provided on the side where the two corresponding limit blocks 13 are close to each other. The sliding shaft 71 slides in cooperation with the longitudinal straight groove 131, and a limit baffle 132 is provided on the front side of the longitudinal straight groove 131. The upper and lower sides of the limit baffle 132 are provided with protrusions, and the upper and lower side walls of the front side of the longitudinal straight groove 131 are provided with grooves that cooperate with the protrusions, and the movable direction of the limit baffle 132 is perpendicular to the length direction of the longitudinal straight groove 131. When placing paper pieces, the placement table 7 can be pulled forward, and pushed in after the paper pieces are placed. Then, the start switch can be pressed to apply glue. The start switch is set at Figure 1 On the limit block 13 shown in .

[0035] like Figure 2 and Figure 6 As shown, it also includes a clamping assembly, which includes electric push rods 8 respectively arranged on the inner sides of the two side plates 11, and the movable ends of the two electric push rods 8 are commonly connected to a pressing plate 81. The clamping assembly can cooperate with the placement table 7 to clamp the paper. By setting the clamping assembly, the operator's hands can be freed to achieve automatic clamping.

[0036] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
