Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing technology, specifically to an adhesive bonding device for corrugated cardboard box processing. Background Technology

[0002] Corrugated boxes are rigid paper boxes made of corrugated cardboard through die-cutting, creasing, stapling or gluing. They are mainly used for packaging and transportation and are widely used in logistics, food, pharmaceutical, electronics, home appliances and other industries. Their structure usually consists of face paper, liner paper and corrugated core paper.

[0003] In the corrugated cardboard processing, gluing equipment is used to apply glue to the cardboard and press multiple layers of material together to achieve bonding. However, existing gluing devices for corrugated cardboard box processing are complex in structure and cannot apply glue to the base paper and the corrugated core simultaneously. Therefore, we propose a new gluing device for corrugated cardboard box processing. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 In this embodiment of the utility model, it includes a housing 1, an adhesive coating assembly 2, a pressing assembly 4, a first feeding groove 7, a second feeding groove 8, and a third feeding groove 9;

[0026] Inside the housing 1, first rotating rollers 5 are equidistantly connected via bearings. A second rotating roller 6 is rotatably connected to one end of the housing 1 via bearings. A geared motor 3 is mounted on one side of the housing 1 via a mounting bracket. Ventilation components 11 are provided on both sides of the housing 1. An adhesive application component 2 is provided at one end of the housing 1. The adhesive application component 2 includes a main pipe 201 mounted to one end of the housing 1 via a mounting bracket. A first solenoid valve 202 is connected to one side of the main pipe 201 via a pipe. The end of the first solenoid valve 202 away from the main pipe 201 is connected to a first connecting pipe 203 via a threaded groove. 03 is located inside the housing 1 and is connected to a first adhesive collection pipe 204 via a pipe joint. The bottom of the first adhesive collection pipe 204 is connected to a first nozzle 205 at equal intervals via threaded grooves. The main pipe 201 is located on one side of the top of the first solenoid valve 202 and is connected to a second solenoid valve 206 via a pipe joint. One end of the second solenoid valve 206 is connected to a second connecting pipe 207 via a threaded groove. The end of the second connecting pipe 207 located inside the housing 1 is connected to a second adhesive collection pipe 208 via a pipe joint. The bottom of the second adhesive collection pipe 208 is connected to a second nozzle 209 at equal intervals via threaded grooves.

[0027] The housing 1 has a first feed trough 7, a second feed trough 8, and a third feed trough 9 sequentially arranged from bottom to top at one end, and a discharge trough 10 at the other end. A first glue collection tube 204 is located inside the housing 1 between the first feed trough 7 and the second feed trough 8, and a second glue collection tube 208 is located inside the housing 1 between the second feed trough 8 and the third feed trough 9. The first glue collection tube 204 is located inside the housing 1 between the first feed trough 7 and the second feed trough 8 to facilitate spraying glue onto the base paper, and the second glue collection tube 208 is located inside the housing 1 between the second feed trough 8 and the third feed trough 9 to facilitate spraying glue onto the corrugated paper core. The opening of the first feed trough 7, the second feed trough 8, and the third feed trough 9 facilitates the insertion of one end of the base paper, the corrugated paper core, and the face paper into the housing 1. The opening of the discharge trough 10 facilitates the removal of the corrugated cardboard from the housing 1.

[0028] The top of the housing 1 is provided with a pressing assembly 4. The pressing assembly 4 includes a vertical rod 401 that passes through and is sleeved at both ends of the top of the housing 1. The bottom end of the vertical rod 401 located inside the housing 1 is connected to a structural frame 402 through a threaded groove. The bottom of the structural frame 402 is rotatably connected to a pressing roller 403 through a bearing. When the vertical rod 401 moves down, the pressing roller 403 at the bottom of the structural frame 402 presses the face paper, corrugated paper core and bottom paper together.

[0029] Among them, the upright 401 is fitted with a compression spring 404 on the outer side inside the housing 1, and the top of the upright 401 is connected to a limit block 405 through a threaded groove. The compression spring 404 is used to push the structural frame 402 to move down.

[0030] Among them, the side of the main pipe 201 away from the first solenoid valve 202 and the second solenoid valve 206 is connected to a valve 210 through a pipe. Opening the valve 210 allows the glue to flow into the main pipe 201.

[0031] The ventilation assembly 11 includes ventilation boxes 1101 fixed to both sides of the housing 1 by bolts. An exhaust fan 1102 is installed inside the ventilation box 1101 by a mounting bracket. Protective nets 1103 are fixed to both sides of the ventilation box 1101 inside the exhaust fan 1102 by bolts. Inspection doors 12 are fixed to both sides of the housing 1 on one side of the ventilation box 1101 by bolts. The operation of the exhaust fan 1102 can accelerate the circulation of gas inside the housing 1. Opening the inspection door 12 allows for maintenance inside the housing 1.

[0032] The working principle of this utility model is as follows: A person connects the device to an external power source using a power cord, connects the discharge end of the glue supply equipment to valve 210, and inserts one end of the base paper, one end of the corrugated paper core, and one end of the face paper sequentially into the housing 1 through the first feed trough 7, the second feed trough 8, and the third feed trough 9, respectively, and extends out from the discharge trough 10. A compression spring 404 pushes the structural frame 402 downwards, pressing the base paper, corrugated paper core, and face paper together via the pressure roller 403. The reduction motor 3 drives the second rotating roller 6 to rotate, which moves the base paper, corrugated paper core, and face paper. Valve 210 is opened, controlling the opening of the first solenoid valve 202 and the second solenoid valve 206. After the first solenoid valve 202 opens, the glue is delivered to the first connecting pipe 203 via the first connecting pipe 206. The glue is sprayed from the glue collection pipe 204 and then from multiple first nozzles 205 onto the base paper, making it easier for the corrugated paper core to adhere to the base paper. After the second solenoid valve 206 is opened, the glue is transported through the second connecting pipe 207 to the second glue collection pipe 208 and then sprayed from the second nozzle 209 onto the corrugated paper core, making it easier for the face paper to adhere to the corrugated paper core. The compression spring 404 pushes the pressure roller 403 to move down, pressing the glued base paper, corrugated paper core and face paper together to form corrugated cardboard. The exhaust fan 1102 in the ventilation box 1101 is turned on, which can extract the gas in the housing 1 through the ventilation box 1101, accelerate the flow of gas in the housing 1, and thus increase the solidification speed of the glue sprayed onto the base paper and corrugated paper core.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
