Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard processing equipment, and in particular to an adhesive device for processing corrosion-resistant multilayer corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a type of board made of two or more layers of cardboard, consisting of a corrugated core and a cover layer. It is commonly known as "corrugated paper" or "corrugated sheet". The corrugations resemble a series of connected arches, arranged side by side and supporting each other to form a triangular structure. It has good mechanical strength, can withstand a certain amount of pressure on a flat surface, and is elastic with good cushioning properties.

[0003] Chinese Patent Publication No. CN219253079U discloses an adhesive device for processing corrosion-resistant multi-layer corrugated cardboard. The device includes a first support plate, with a motor assembly fixedly mounted on its lower end. A first transmission assembly is fixedly sleeved onto the output shaft of the motor assembly, and a bevel gear assembly is movably connected to the upper end of the first transmission assembly. This invention uses a transmission shaft to drive a lead screw and an extrusion plate downwards, squeezing the glue in the glue bucket's inner cavity into the glue delivery tube's inner cavity and then into the lower glue body's inner cavity. When the top surface of the corrugated cardboard body to be coated with glue passes the lower end of a baffle plate, it pushes the baffle plate to the right, causing the glue in the lower glue body's inner cavity to flow along the baffle plate to the top surface of the corrugated cardboard body to be coated with glue. When the corrugated cardboard body is no longer connected to the baffle plate, the baffle plate returns to its original position under the action of a connecting spring, preventing the glue in the lower glue body's inner cavity from flowing out and reducing glue waste.

[0004] In the above-mentioned technology, when the top surface of the corrugated paper body to be coated with glue passes the lower end of the glue-stopping plate, the glue-stopping plate will be pushed to the right, so that the glue in the lower glue-stopping cavity flows along the glue-stopping plate to the top surface of the corrugated paper body to be coated with glue. When the corrugated paper body and the glue-stopping plate are no longer connected, the glue-stopping plate returns to its original position under the action of the connecting spring, preventing the glue in the lower glue-stopping cavity from flowing out and reducing glue waste. However, in actual operation, due to the limited passing speed of the corrugated paper body, it is easy to have excessive glue supply or insufficient glue supply, resulting in poor glue coating continuity and difficulty in ensuring the firmness of subsequent bonding. Therefore, this utility model discloses an bonding device for processing corrosion-resistant multi-layer corrugated cardboard to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive device for processing corrosion-resistant multilayer corrugated cardboard, in order to solve the problems mentioned in the background art, such as the tendency of traditional corrugated cardboard adhesive equipment to over-supply or under-supply glue, poor glue application continuity, and difficulty in ensuring the strength of subsequent bonding.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] An adhesive device for processing corrosion-resistant multilayer corrugated cardboard includes support side plates and multiple reinforcing rods fixed between two support side plates. A corrugated paper conveying assembly and a guiding assembly are installed between the two support side plates. A pressure application assembly and multiple glue application assemblies are respectively provided above the corrugated paper conveying assembly and on both sides of the guiding assembly. All glue application assemblies are connected to a pumping assembly.

[0008] The glue application assembly includes a glue box fixed between two support side plates, a first motor screwed to the outer wall of one of the support side plates, and a roller brush rotatably connected between the inner walls of both ends of the glue box. The glue box has an opening at the top, and glue strips that contact the outer wall of the roller brush are embedded on both sides of the opening.

[0009] As a further embodiment of this utility model, the corrugated paper conveying assembly includes a plurality of conveying rollers rotatably connected between the supporting side plates and a second motor screwed to the outer wall of one of the supporting side plates. The conveying rollers are all located in the same horizontal plane, and the output end of the second motor is fixedly connected to one of the conveying rollers.

[0010] As a further embodiment of this utility model, the pressure application assembly includes a vertical groove located on the support side plate, a support horizontal plate fixedly connected between the tops of the two vertical grooves, and a concave frame slidably connected between the two vertical grooves. A pressure roller is rotatably connected between the inner walls of both ends of the concave frame. A vertical lead screw is threadedly connected to the middle of the support horizontal plate. A first handle is fixedly connected to the top of the vertical lead screw. The bottom of the vertical lead screw is rotatably connected to the concave frame, and the pressure roller is located directly above the transmission roller connected to the transmission roller.

[0011] As a further embodiment of this utility model, the guide assembly includes a guide rod and a double-ended lead screw rotatably connected between two support side plates. Two sliders are slidably sleeved on the outer side of the guide rod. The two sliders are threadedly connected to both ends of the double-ended lead screw. One end of the double-ended lead screw passes through the support side plate and is fixedly connected to a second handle. A vertical shaft is fixedly connected to the upper side of the slider. A guide roller is rotatably sleeved on the outer side of the vertical shaft.

[0012] As a further embodiment of this utility model, the pumping assembly includes a glue pump and a glue tank fixedly connected to the outer wall of one of the supporting side plates. The input end of the glue pump is connected to the bottom of the glue tank, and the output end of the glue pump is connected to two liquid guide pipes through a diversion valve. The two liquid guide pipes are respectively connected to the bottom of the glue box. A return branch pipe is fixedly embedded on one side of the middle part of the glue box, and the return branch pipes are connected to the glue tank through the return main pipe.

[0013] As a further embodiment of this utility model, a transparent window is embedded on one side of the glue box, a liquid filling pipe is embedded in the top wall of the glue box, and a pipe cap is fitted over the outer side of the top of the liquid filling pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model discloses an adhesive device for processing corrosion-resistant multi-layer corrugated cardboard. Rotating the second handle drives the double-ended screw thread to bring two sliders closer together, thereby adjusting the spacing between the guide rollers to accommodate corrugated cardboard of different widths. Rotating the first handle drives the vertical screw to rotate, and as the vertical screw spirals downward, it causes the concave frame to descend, allowing the pressure roller to press the corrugated cardboard and the cover layer tightly. This device is suitable for corrugated cardboard of different thicknesses, ensuring the alignment and adhesion of the adhesive, and improving the versatility and applicability of the equipment.

[0016] This utility model discloses an adhesive device for processing corrosion-resistant multi-layer corrugated cardboard. A second motor drives a conveyor roller, which, under the action of friction, can move the corrugated cardboard and the cover layer forward together. At the same time, a first motor drives a roller brush to rotate, so that the roller brush can pick up glue and apply it to the underside of the cover layer. Until the corrugated cardboard and the cover layer are combined, the glue can adhere to the adjacent sides of the corrugated cardboard and the cover layer, thus completing the bonding process. This realizes the automatic conveying and gluing of the corrugated cardboard and the cover layer, simplifies the gluing process, reduces manual intervention, improves production efficiency, and compared with traditional dispensing or spraying methods, can more evenly cover the entire bonding surface, ensuring the strength of the bond.

[0017] This utility model discloses an adhesive bonding device for processing corrosion-resistant multi-layer corrugated cardboard. The adhesive pump continuously draws adhesive from the adhesive tank to the diversion valve. The diversion valve distributes the adhesive evenly to two adhesive boxes through the liquid guide pipe. When the adhesive in the adhesive box reaches the safe liquid level, the excess adhesive will flow back to the adhesive tank from the return branch pipe and the return main pipe, avoiding excessive adhesive supply and waste, and ensuring the bonding quality.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-6 This utility model provides an adhesive device for processing corrosion-resistant multilayer corrugated cardboard, including a support side plate 1 and a plurality of reinforcing rods 11 fixed between the two support side plates 1. Preferably, there are four reinforcing rods 11, and the four reinforcing rods 11 are respectively connected between the four corners of the support side plate 1, which can fully ensure the stability of the structure.

[0028] Furthermore, a corrugated paper conveying assembly 2 is installed between the two supporting side plates 1. The corrugated paper conveying assembly 2 includes a plurality of conveying rollers 21 rotatably connected between the supporting side plates 1 and a second motor 22 screwed to the outer wall of one of the supporting side plates 1. The conveying rollers 21 are all located in the same horizontal plane, and the output end of the second motor 22 is fixedly connected to one of the conveying rollers 21.

[0029] Specifically, the second motor 22 drives one of the transmission rollers 21, which, under the action of friction, can drive the corrugated core layer and the cover layer forward together. The remaining transmission rollers 21 roll under the drive of the corrugated core layer, which can significantly reduce frictional resistance and adapt to the transmission needs of cardboard of different lengths.

[0030] Furthermore, a guide assembly 3 is further installed between the two support side plates 1. The guide assembly 3 includes a guide rod 31 and a double-ended lead screw 32 rotatably connected between the two support side plates 1. Two sliders 33 are slidably sleeved on the outer side of the guide rod 31. The two sliders 33 are respectively threaded to both ends of the double-ended lead screw 32. One end of the double-ended lead screw 32 passes through the support side plate 1 and is fixedly connected to a second handle 34. A vertical shaft 35 is fixedly connected to the upper side of the slider 33. A guide roller 36 is rotatably sleeved on the outer side of the vertical shaft 35.

[0031] Specifically, rotating the second handle 34 causes the double-ended lead screw 32 to drive the two sliders 33 to move closer to each other, thereby adjusting the spacing between the guide rollers 36 to accommodate corrugated cardboard of different widths. The guide rollers 36, which are rotatably connected to the vertical shaft 35, can reduce transmission friction.

[0032] Furthermore, above the corrugated paper conveying assembly 2 and on both sides of the guide assembly 3, a pressure application assembly 4 and a plurality of glue application assemblies 5 are respectively provided. The pressure application assembly 4 includes a vertical groove 41 located on the support side plate 1, a support horizontal plate 42 fixedly connected between the tops of the two vertical grooves 41, and a concave frame 43 slidably connected between the two vertical grooves 41. A pressure roller 46 is rotatably connected between the inner walls of the two ends of the concave frame 43. A vertical lead screw 44 is threadedly connected to the middle of the support horizontal plate 42. A first handle 45 is fixedly connected to the top of the vertical lead screw 44. The bottom of the vertical lead screw 44 is rotatably connected to the concave frame 43. The pressure roller 46 is located directly above the conveying roller 21 connected to the conveying roller 21.

[0033] Specifically, rotating the first handle 45 causes the vertical lead screw 44 to rotate. As the vertical lead screw 44 spirals downward, it causes the concave frame 43 to descend, so that the pressure roller 46 can press the corrugated core layer and the cover layer, which is suitable for corrugated cardboard of different thicknesses.

[0034] Furthermore, the glue application assembly 5 includes a glue box 51 fixed between two support side plates 1, a first motor 52 screwed to the outer wall of one of the support side plates 1, and a roller brush 53 rotatably connected between the inner walls of both ends of the glue box 51. The glue box 51 has an opening at the top, and glue strips 54 that contact the outer wall of the roller brush 53 are embedded on both sides of the opening.

[0035] Specifically, the corrugated cardboard consists of a corrugated core layer and multiple cover layers. The cover layers are placed on top of different roller brushes 53. During the forward transmission of the corrugated core layer and cover layers, the cover layers are in close contact with the roller brushes 53 under the action of gravity. The roller brushes 53 can separate the corrugated core layer and cover layers, allowing the cover layers to be bonded after the glue is applied. During this process, the first motor 52 drives the roller brushes 53 to rotate, allowing the roller brushes 53 to pick up glue and apply it to the underside of the cover layers. After the corrugated core layer and cover layers are combined, the glue can adhere to the adjacent sides of the corrugated core layer and cover layers, thus completing the bonding process. It is worth noting that the outer wall of the roller brushes 53 is provided with a pile layer. The pile layer can fully adhere to the glue until the pile layer is squeezed by the glue strip 54 and excess glue is squeezed out, which ensures that the cover layers in contact with the pile layer can be glued evenly and ensures the bonding quality.

[0036] Furthermore, each of the glue application components 5 is connected to the pumping component 6. The pumping component 6 includes a glue pump 61 and a glue tank 62 fixedly connected to the outer wall of one of the supporting side plates 1. The input end of the glue pump 61 is connected to the bottom of the glue tank 62. The output end of the glue pump 61 is connected to two liquid guide pipes 64 through a diversion valve 63. The two liquid guide pipes 64 are respectively connected to the bottom of the glue box 51. A return branch pipe 65 is fixedly embedded on one side of the middle part of the glue box 51. The return branch pipes 65 are all connected to the glue tank 62 through the return main pipe 66.

[0037] Specifically, the glue pump 61 continuously draws glue from the glue tank 62 to the diversion valve 63. The diversion valve 63 distributes the glue evenly to the two glue boxes 51 through the liquid guide pipe 64. When the glue in the glue box 51 reaches the safe level, the excess glue will flow from the return branch pipe 65 and the return main pipe 66 back to the glue tank 62, avoiding excessive glue supply and glue waste, and ensuring the uniformity of glue application and the quality of bonding.

[0038] Furthermore, a transparent window 67 is embedded on one side of the glue box 62, and a liquid filling pipe 68 is embedded in the top wall of the glue box 62. A pipe cap 69 is fitted onto the outer side of the top of the liquid filling pipe 68.

[0039] Specifically, the transparent window 67 is used to observe the glue level in the glue tank 62, so as to know the remaining amount of glue in time and ensure the normal operation of the equipment; the filling pipe 68 is used to replenish glue in the glue tank 62 to ensure the continuity of glue supply; the pipe cover 69 is used to seal the filling pipe 68 to prevent glue leakage or impurities from entering the glue tank 62, and to ensure the cleanliness of the glue and the normal operation of the equipment.

[0040] Working principle:

[0041] Before use, turn the second handle 34. The second handle 34 drives the double-headed screw 32 to drive the two sliders 33 to move closer to each other, so that the spacing between the guide rollers 36 can be adjusted to adapt to corrugated cardboard of different widths. The corrugated core layer is placed on the upper side of the transfer roller 21, and the cover layer is placed on the upper side of the different roller brushes 53. Both the corrugated core layer and the cover layer pass through the gap between the pressure roller 46 and the adjacent transfer roller 21. Turn the first handle 45. The first handle 45 drives the vertical screw 44 to rotate. As the vertical screw 44 moves down spirally, it drives the concave frame 43 to descend, so that the pressure roller 46 can press the corrugated core layer and the cover layer tightly. It is suitable for corrugated cardboard of different thicknesses.

[0042] In use, the second motor 22 drives the transmission roller 21, which, under the action of friction, can drive the corrugated core layer and the cover layer forward together. At the same time, the first motor 52 drives the roller brush 53 to rotate, so that the roller brush 53 can pick up glue and apply it to the underside of the cover layer. Until the corrugated core layer and the cover layer are combined, the glue can adhere to the adjacent sides of the corrugated core layer and the cover layer, so that the two complete the bonding process. It is worth noting that during the above process, the glue pump 61 continuously draws glue from the glue tank 62 to the diversion valve 63. The diversion valve 63 distributes the glue evenly to the two glue boxes 51 through the liquid guide pipe 64. When the glue in the glue box 51 reaches the safe liquid level, the excess glue will flow from the return branch pipe 65 and the return main pipe 66 back to the glue tank 62, avoiding the situation of excessive glue supply and glue waste, and ensuring the uniformity of glue application and the quality of bonding.
