Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a glue coating device with an anti-overflow mechanism. Background Art

[0002] Gluing refers to the process of evenly applying glue, including solvent glue, latex and water glue, to the surface of an object. There are four methods of gluing: scraping, roller coating, dipping and spraying. When making very thin tape that requires high air permeability and water resistance, it is appropriate to use the gluing method for multiple times. Paper packaging boxes need to be glued when in use.

[0003] For example, publication number CN217250185U discloses a gluing device for paper product manufacturing. The device is provided with rollers and hoses. Glue flows to the rollers through the hoses, providing glue liquid continuously. The glue is applied by the rollers, making the gluing more uniform and greatly improving the efficiency of gluing.

[0004] However, when the gluing device is in use, the glue flows onto the roller through the hose, and the liquid inside the hose keeps flowing downward, which causes the liquid to overflow at the roller, thereby causing waste and affecting subsequent processing. In view of this, we propose a gluing device with an anti-overflow mechanism. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a glue coating device with an anti-overflow mechanism, comprising a frame 1, a conveying structure 2 is arranged on the upper end of the frame 1, two groups of brackets 5 are fixedly installed on the upper end of the frame 1, two groups of solution tanks 6 are fixedly installed on the upper end of the bracket 5, a glue coating structure 3 is arranged on the lower end of the bracket 5, and the glue coating structure 3 includes a connecting block 31 fixedly installed on the lower end of the solution tank 6, a connecting plate 32 is fixedly installed on the lower end of the connecting block 31, a side wall of the connecting plate 32 is rotatably connected to one end of a rotating rod 33, and a glue coating roller 34 is fixedly installed on the other end of the rotating rod 33, One end of a connecting strip 35 is fixedly mounted on the side wall of the connecting plate 32, and an arc frame 36 is fixedly mounted on the other end of the connecting strip 35. Slide grooves 37 are provided on both sides of the arc frame 36. A slide rod 38 is fixedly mounted on the inner wall of the slide groove 37. A sleeve 39 is slidably connected to the surface of the slide rod 38. A return spring 310 is provided on the surface of the slide rod 38. A placement plate 333 is fixedly mounted on the side wall of the sleeve 39. A liquid passing pipe 311 is fixedly mounted at the lower end of the solution tank 6. The lower end of the liquid passing pipe 311 is fixedly connected to the upper end of the arc frame 36, and a control valve 312 is provided on the surface of the liquid passing pipe 311.

[0025] Specifically, the glue coating structure 3 of the technical solution of the utility model includes: a connecting block 31, a connecting plate 32, a rotating rod 33, a glue coating roller 34, a connecting strip 35, an arc frame 36, a slide groove 37, a slide rod 38, a sleeve 39, a return spring 310, a liquid pipe 311, and a control valve 312.

[0026] In one embodiment of the utility model, a gluing structure 3 is provided to facilitate gluing the surface of the paperboard. The conveying structure 2 is a prior art disclosed in the original application and will not be described in detail here. An arc frame 36 is provided to contact the surface of the gluing roller 34. The gluing roller 34 rotates on the surface of the connecting plate 32 through the rotating rod 33 on its side wall. A connecting strip 35 is provided to support and fix the arc frame 36. When in use, the user can open the solution tank 6 and the control valve 312. At this time, the liquid inside the solution tank 6 will move downward through the liquid pipe 311 into the arc frame 36, and the liquid will be stored through the placement plate 333.

[0027] When more and more colloid is placed on the upper end of the placement plate 333, the placement plate 333 will move through the sleeve 39 on its side wall. At this time, the sleeve 39 slides on the surface of the slide rod 38 and squeezes the return spring 310. At this time, the movement of the placement plate 333 will drive the toothed plate 9 on its upper end to move, and the toothed plate 9 will drive the rotating gear 8 meshing with it to rotate. The rotating gear 8 will drive the valve stem 7 inside it to rotate. When the valve stem 7 rotates to a certain extent, the control valve 312 will be closed, so that the colloid can be released. The colloid will not fall down to avoid overflow. At this time, the colloid will accumulate inside the arc frame 36 and contact the glue coating roller 34, so that the glue coating roller 34 will coat the paperboard with glue when rotating. When the colloid accumulated on the upper end of the placement plate 333 becomes less, the placement plate 333 will move upward under the elastic force 310 of the return spring, thereby driving the tooth plate 9 to move upward and driving the valve stem 7 to rotate, so that the control valve 312 opens to make the colloid fall. After a certain amount is added, the control valve 312 will automatically close to avoid colloid overflow.

[0028] In addition, by providing the limiting structure 4, it is convenient to limit the gluing work of the gluing roller 34. When in use, the user can move the pull block 43 to drive the baffle 42 to move. The baffle 42 moves inside the arc frame 36 to block the inside of the arc frame 36 to a certain extent, so that the user can effectively adjust the gluing position when gluing cardboards of different widths, thereby avoiding a part of the gluing roller 34 from being unable to contact the cardboard during gluing, thereby preventing accumulation and affecting use, and further improving the use effect of the device.

[0029] Please continue reading Figure 1-Figure 5, a valve stem 7 is arranged at one end inside the control valve 312, a rotating gear 8 is fixedly installed at the other end of the valve stem 7, a tooth plate 9 is fixedly installed at the upper end of the placement plate 333, and the upper end of the tooth plate 9 passes through the side wall of the arc frame 36, the arc frame 36 is provided with a limiting structure 4, and the limiting structure 4 is fixedly installed on the directional cylinder 41 of the side wall of the arc frame 36, and a baffle 42 is slidably connected to the inner wall of the directional cylinder 41, and a pull block 43 is fixedly installed at one end of the baffle 42, and the other end of the baffle 42 passes through the inner wall of the arc frame 36, and a clamping plate 10 is fixedly installed on the side wall of the arc frame 36, and a plurality of groups of bayonet holes 11 are opened on the surface of the clamping plate 10, and a T-shaped clamping rod 12 is passed through the surface of the pull block 43, one end of the reset spring 310 is fixedly connected to the inner wall of the slide groove 37, and the other end of the reset spring 310 is fixedly connected to the side wall of the sleeve 39, and the arc frame 36 and the glue coating roller 34 are in a close contact state.

[0030] During operation, the user can open the solution tank 6 and the control valve 312. At this time, the liquid inside the solution tank 6 will move downward through the liquid passage 311 into the arc frame 36. The liquid will be stored through the placement plate 333. When the colloid on the upper end of the placement plate 333 increases, the placement plate 333 will move through the sleeve 39 on its side wall. At this time, the sleeve 39 slides on the surface of the slide rod 38 and squeezes the reset spring 310. At this time, the movement of the placement plate 333 will drive the tooth plate 9 to move, and the movement of the tooth plate 9 will drive the rotating gear 8 to rotate. The rotation of the rotating gear 8 drives the valve stem 7 to rotate. When the valve stem 7 rotates to a certain extent, the control valve 312 will be closed, so that the colloid will not The glue coating roller 34 is used to coat the paperboard with glue. When the glue on the upper end of the placing plate 333 is less, the placing plate 333 moves upward under the elastic force 310 of the return spring, thereby driving the tooth plate 9 to move upward and driving the valve stem 7 to rotate, so that the control valve 312 opens and the glue falls. When coating paperboards of different widths, the user can move the pull block 43 to drive the baffle plate 42 to move. The baffle plate 42 moves inside the arc frame 36 to shield the inside of the arc frame 36 to a certain extent, further improving the use effect of the device.
