Description

Technical Field

[0001] The invention relates to the field of corrugated paper, in particular to a high-viscosity folder gluing machine. Background Art

[0002] In the production process of corrugated paper factories, in many assembly lines or processing scenarios, glue is often needed to be added to the surface of cartons and paper to assist in thickening, bonding or shaping and fixing. However, the surface of the glue wheel in the traditional box-gluing device is a smooth surface. Such gluing efficiency often has the problem of insufficient glue amount affecting the adhesion, and at the same time, there is also the problem of uneven glue bonding affecting the adhesion. This requires additional quality inspection links, and once a problem occurs, it leads to rework and processing, which reduces the product qualification rate and quality, wastes labor costs and glue reserves, and generally increases the cost and quality of production.

[0003] In order to solve the above problems, a high-viscosity folder gluer is designed, which can apply glue evenly, with sufficient and controllable glue amount and reliable viscosity. Summary of the invention

[0004] In view of the above-mentioned problems, the purpose of the present invention is to develop a high-viscosity folder gluer so that the glue can be evenly applied to the paper, the amount of glue is sufficient and controllable, the viscosity is reliable, and the glue can be recycled.

[0005] In order to solve the problems existing in the above-mentioned prior art, the technical solution of the present invention is:

[0006] A high-viscosity box gluing machine includes a frame, a gluing device and a motor cabinet. The frame is provided with a conveyor belt. The gluing device includes a glue top groove, a glue discharge valve, a gluing roller and a back-gluing roller arranged in sequence from top to bottom. A gluing plate is provided below the glue discharge valve. The gluing plate is tilted downward and abuts against the surface of the gluing roller. The surface of the gluing roller is provided with a plurality of convex patterns. A motor for driving the back-gluing roller to rotate is provided in the motor cabinet. The gluing roller and the back-gluing roller are gear-driven. The carton is transported to the gluing device by the conveyor belt on the frame. The glue falls from the glue top groove above and is applied to the gluing roller. The gluing roller with convex patterns rolls over the upper surface of the carton, and pits corresponding to the convex patterns are formed on the upper surface of the carton, so that the glue can not only be evenly applied to the surface of the carton, but also part of the glue can be stored in the pits. The adhesion near the pits is the best, which improves the amount of glue applied as a whole, helps the subsequent bonding steps, improves the overall product quality, and avoids rework production of paper with insufficient viscosity.

[0007] Preferably, the convex patterns cover the entire surface of the glue roller, and the convex patterns are arranged at equal intervals on the surface of the glue roller. The evenly arranged convex patterns are pressed on the paper, which can produce even pits on the paper, so that the glue is evenly stored in the pits, and the overall adhesion is evenly improved, further improving the product quality.

[0008] Preferably, each convex pattern is ellipsoidal or spherical. The spherical convex pattern can reduce the tension of rolling the paper and avoid the paper from breaking when the pits are pressed.

[0009] Preferably, the thickness of each convex pattern is 0.5mm-1.2mm. If the thickness of the convex pattern is too low, the effect is not good, or if the convex pattern is too deep, the paper is easily crushed. The thickness of the convex pattern and the thickness between the gluing roller and the paper are well controlled, preferably 0.6mm-0.9mm, to ensure the rolling effect and increase the amount of glue applied, so as to achieve effective bonding.

[0010] Preferably, a back-paste plate is provided on the back-paste roller, and the back-paste plate is tilted upward and pressed against the surface of the back-paste roller, and a paste groove is provided below the back-paste roller. The back-paste plate is pressed against the back-paste roller, and the paste adhering to the back-paste roller is scraped off and dropped into the paste groove below by the tangential action of the pressing, so as to recover the excess paste.

[0011] Preferably, an oblique flow groove is provided on the side wall of the glue tank, a glue box is provided below the oblique flow groove, and an extraction handle is provided on the glue box. Excess glue overflowing from the glue tank flows into the glue box. When the glue box is full, the operator can hold the extraction handle and pour the glue in the glue box into the top glue box, and then flow into the upper glue roller for bonding.

[0012] Preferably, there are four paste-draining valves, and each of the paste-draining valves is arranged at equal intervals on the same side of the top groove of the paste. Multiple paste-draining valves are arranged because the fluidity of the paste is poor and the viscosity is high. By increasing the number of valves, the laying of the paste is accelerated. The valve size of the paste-draining valve can be adjusted to adjust the flow of the paste.

[0013] Preferably, an upper gear is provided on the main shaft of the upper glue roller, and a lower gear and a driving gear are provided at both ends of the main shaft of the return glue roller respectively. The driving gear is connected to the motor chain transmission, and the lower gear drives the upper gear to rotate.

[0014] The beneficial effects of the present invention are as follows: pits are generated when the gluing roller with convex patterns rolls over the upper surface of the carton, and the glue is evenly stored in the pits, thereby evenly improving the overall adhesion. Moreover, the adhesion near the pits is the best, thereby increasing the amount of glue applied as a whole, facilitating subsequent gluing steps, improving the overall product quality, and avoiding rework production due to insufficient paper viscosity.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment:

[0023] like Figure 1 As shown: a high-viscosity box gluing machine comprises a frame 1, a gluing device 2 and a motor cabinet 3, and a conveyor belt 11 is arranged on the frame 1.

[0024] like Figure 2 As shown, the gluing device 2 includes a glue top tank 21, a glue drain valve 211, an upper glue roller 22 and a return glue roller 23 which are arranged in sequence from top to bottom. An upper glue plate 221 is arranged below the glue drain valve. The upper glue plate 221 is tilted downward and abuts against the surface of the upper glue roller 22. A large number of convex patterns 220 are arranged on the surface of the upper glue roller 22. A motor 31 for driving the return glue roller to rotate is arranged in the motor cabinet 3. The upper glue roller 22 and the return glue roller 23 are gear-driven. The carton is transported to the gluing device 2 by the conveyor belt 11 on the frame 1, and the glue falls from the glue top groove 21 above to the gluing plate 221, and then evenly spread on the gluing roller 22 by the gluing plate. The gluing roller 22 with convex patterns rolls over the upper surface of the carton, and forms pits corresponding to the shape of the convex patterns 220 on the upper surface of the carton, so that the glue can not only be evenly spread on the surface of the carton, but also part of the glue can be stored in the pits. The adhesion near the pits is the best, which increases the amount of glue applied as a whole, helps the subsequent gluing steps, improves the overall product quality, and avoids rework production due to insufficient paper viscosity.

[0025] The back-paste roller 23 is provided with a back-paste plate 231, which is tilted upward and abutted against the surface of the back-paste roller 23, and a paste groove 24 is provided below the back-paste roller 23. The back-paste plate abuts against the back-paste roller, and by a tangential action of abutment, the glue adhering to the back-paste roller is scraped off and falls into the glue groove below, so as to recover the excess glue.

[0026] like Figure 3 As shown: the convex patterns cover the surface of the gluing roller 22, and the convex patterns 220 are arranged at equal intervals on the surface of the gluing roller 22. Each convex pattern 220 is elliptical or spherical, and the thickness of each convex pattern 220 is 0.8 mm. The uniformly arranged convex patterns 220 are pressed on the paper, which can produce uniform pits on the paper, so that the paste is evenly stored in the pits, and the adhesion is uniformly improved as a whole, and the product quality is further improved. If the thickness of the convex patterns is too low, the effect is not good, or if the convex patterns are too deep, the paper is easily crushed. The thickness of the convex patterns and the thickness between the gluing roller 22 and the paper are controlled, preferably in the range of 0.6 mm to 0.9 mm, and 0.8 mm is specifically used, which can ensure the rolling effect and increase the amount of paste, and achieve effective adhesion.

[0027] like Figure 4 Schematic diagram: a slant flow slot 241 is provided on the side wall of the paste tank 24, a paste box 25 is provided below the slant flow slot 241, and a pick-up handle 251 is provided on the paste box 25. The excess paste overflowing from the paste tank 24 flows into the paste box 25. When the paste box 25 is full, the operator can hold the pick-up handle 251 and pour the paste in the paste box 25 into the topmost paste box 21, and then flow into the upper paste roller 22 for bonding.

[0028] There are four paste-draining valves 211, and each of the paste-draining valves is arranged at equal intervals on the same side of the paste top groove 21. Multiple paste-draining valves are arranged because the paste has poor fluidity and high viscosity. By increasing the number of valves, the laying of the paste is accelerated. The valve size of the paste-draining valve 211 can be adjusted to adjust the flow rate of the paste.

[0029] like Figure 5 As shown: an upper gear 222 is provided on the main shaft of the upper glue roller 22, and a lower gear 232 and a driving gear 233 are provided at both ends of the main shaft of the return glue roller 23 respectively. The driving gear 233 is connected to the motor 31 through a chain transmission, and the lower gear 232 drives the upper gear to rotate.

[0030] In the present invention, a gluing roller with convex patterns rolls over the upper surface of a carton to generate pits, and the paste is evenly stored in the pits, thereby evenly improving the overall adhesion. Moreover, the adhesion near the pits is the best, thereby increasing the amount of paste applied as a whole, facilitating subsequent gluing steps, improving the overall product quality, and avoiding rework production due to insufficient paper viscosity.

[0031] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technology can understand and think of any changes or substitutions within the technical scope disclosed by the present invention, which should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
