[0023] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 8 The multi-channel double-end glue coating machine described in the present invention includes a glue melting boiler 1, a glue coating frame 2, a plurality of glue coating mechanisms 3 installed on the glue coating frame 2, a feeding table 4 and a discharging table 5, wherein the feeding table 4 and the discharging table 5 are respectively located on both sides of the glue coating mechanism 3, each glue coating mechanism 3 corresponds to a workstation, and multi-station operation can be realized. The glue melting boiler 1 is connected to a plurality of feeding nozzles 6 through a pipeline, and the glue melting boiler sets the temperature in a certain range. The glue melting boiler 1 heats the glue and sends it to the feeding nozzle 6, and the feeding nozzle 6 then adds the glue to the glue coating mechanism 3 for use. The glue coating mechanism 3 includes a material storage box 31, a discharge valve 32 arranged on the side of the material storage box 31, and a glue coating roller 33 and a scraper closely connected to the discharge valve 32. The feeding nozzle 6 is located above the material storage box 31 to deliver glue to the material storage box 31. A plurality of feeding components are arranged between the feed table 4 and the discharge table 5. The feeding components are used to transport sheet materials. Each of the feeding components is arranged between the two glue coating rollers 33. The two glue coating rollers 33 apply glue to the side of the sheet material passing through the feeding components. It also includes an active motor 7, which drives the glue coating roller 33 and the feeding component to move at the same time through a gear set. The active motor 7 drives multiple connecting rods to rotate at the same time through the gear set. The multiple connecting rods are connected to the feeding roller group 35 and the glue coating roller 33 through a universal joint. This can save the number of motors used, facilitate control, and reduce costs.

[0025] Specifically, each of the feeding components includes a supporting plate 34 located at the bottom of both sides and a feeding roller group 35 located in the middle of both sides. The width of the supporting plate 34 is relatively narrow, and is used to support the sheet material, reduce the contact surface between the sheet material and the supporting plate 34, and reduce friction. The width between the two groups of feeding roller groups 35 is adjusted by an adjustment mechanism. For different sheet materials, the width between the two groups of feeding roller groups 35 can be changed, so that the sheet material is stuck between the two groups of feeding roller groups 35 for transportation. A group of pressing roller groups 36 is also provided above one of the feeding roller groups 35 to press the sheet material. The height of the pressing roller group 36 is adjusted by adjusting the manual screw 37. For sheets of different thicknesses, the manual screw 37 can be adjusted to press the sheet material to prevent the sheet material from moving upward.

[0026] Specifically, one of the feed roller groups 35 is installed on a feed fixed bracket 38, and the feed fixed bracket 38 is fixed to the glue coating frame 2. The feed roller group 35 on the other side is installed on a feed adjustment bracket 39, and the feed adjustment bracket 39 is slidably connected to the glue coating frame 2. The adjustment mechanism includes an adjustment motor 310 installed on the glue coating frame 2, and an adjustment screw 311 threadedly connected to the feed adjustment bracket 39. The adjustment screw 311 is rotatably installed on the glue coating frame 2. The adjustment motor 310 is connected to the adjustment screw 311 through a belt and drives the adjustment screw 311 to rotate, so that the feed adjustment bracket 39 will move relative to the feed fixed bracket 38, thereby changing the width between the two feed roller groups 35, so that it can be suitable for sheets of different widths.

[0027] Specifically, a pressing bracket 312 is slidably connected to the top of the feeding adjustment bracket 39 via two sliding rods. A manual screw 37 is rotatably provided on the feeding adjustment bracket 39. The manual screw 37 is threadedly connected to the pressing bracket 312. The height of the pressing bracket 312 can be adjusted by rotating the manual screw 37. The pressing roller group 36 is installed on the pressing bracket 312.

[0028] Specifically, an arc-shaped water receiving groove 313 is provided at the bottom of the glue coating roller 33, and the water receiving groove 313 is fixed on the glue coating frame 2. The water receiving groove 313 is connected to a drainage groove 314 extending from the outside of the glue coating frame 2 through a notch, and the drainage groove 314 is also fixed on the glue coating frame 2. In this way, when the storage box 31 needs to be cleaned, waste water can enter the drainage groove 314 through the water receiving groove 313, and then be discharged from the outside of the glue coating frame 2, so as to facilitate the cleaning of the storage box 31.

[0029] Specifically, a liquid level meter is provided in the material storage box 31, and a solenoid valve switch is provided on the feeding nozzle 6. The controller controls the feeding nozzle 6 to add glue to the material storage box 31 through the electrical signal sent back by the liquid level meter. In order to ensure that the glue coating roller 33 discharges glue evenly, the glue level in the material storage box 31 must be ensured. Therefore, a liquid level meter is provided in the material storage box 31 to solve this problem.

[0030] Specifically, the discharge valve 32 includes two relatively matched scraper plates 321, and the cross-section of the scraper plates 321 is semicircular. By adjusting the angles of the two scraper plates 321 to change the opening size of the discharge valve 32, the amount of glue discharged can be controlled. At the same time, by changing the angle of the scraper plates 321, the thickness of the glue on the surface of the glue coating roller 33 can be changed.

[0031] The present invention has a high degree of automation. It only needs to manually place the sheet material on the gluing mechanism 3. For sheets of different widths, the distance between the two groups of feeding rollers 35 can be adjusted by adjusting the motor 310. For sheets of different thicknesses, the height of the pressing roller group 36 can be adjusted by adjusting the manual screw 37. The present invention has a fast gluing speed and multi-station operation, which greatly improves the gluing efficiency. A main motor is used to drive the gluing roller 33 and the feeding component to move, which has low energy consumption and is easy to control.
