Description

Technical Field

[0001] The present invention relates to the technical field of cured resins, and particularly to a cold-curing plywood resin, its production and processing method, and application. Background Art

[0002] Cold-curing plywood resin is an adhesive that can cure under low-temperature conditions and is mainly used in the manufacture of plywood. This resin can cure quickly at room temperature and has the advantages of low curing exotherm, small thermal shrinkage, and good weather resistance.

[0003] Common types of cold-curing plywood resins: epoxy resin, phenolic resin, polyisocyanate, acrylic resin, UV resin, UV resin, acrylic acid resin, polyurethane resin, etc. Phenolic resin is also a common cold-curing adhesive and has good heat resistance and chemical corrosion resistance. It is usually used in the manufacture of high-temperature-resistant plywood, laminates, and friction materials, etc.

[0004] Currently, the existing one, such as the patent application number CN202111626577.X, discloses a nano-wave-absorbing particle-modified phenolic resin adhesive and its preparation method, and discloses that it is made of the following components by weight: 100-120 parts of modified phenolic resin, 20-30 parts of nano-wave-absorbing particle-modified polymer, 0.5-100 parts of plasticizer, 100-300 parts of functional filler, 2-5 parts of β-(3,4-epoxycyclohexyl)ethyltriethoxysilane, 1-3 parts of cashew phenol, 18-25 parts of ethylene glycol, 0.5-10 parts of functional catalyst, etc. The nano-wave-absorbing particle-modified phenolic resin adhesive produced by the present invention significantly shortens the curing time of plywood while greatly improving the strength of plywood, and at the same time significantly reduces the release amount of free formaldehyde and free phenol in plywood, making it more environmentally friendly.

[0005] Although the above patent discloses the preparation method of cold-curing plywood resin, the preparation method of cold-curing plywood resin still requires the relevant specific production and processing process, and there are still some deficiencies in the existing cold-curing plywood resin during the production and processing process. The specific deficiencies are as follows:

[0006] First, in the existing production and processing process of cold-curing plywood resin, during the process of bagging the prepared cold-curing plywood resin, for the preparation of the packaging bag before filling, it is often necessary to purchase prefabricated packaging bags from a third-party packaging. The price of purchasing prefabricated packaging bags is high, and during the process of filling cold-curing plywood resin into the packaging bag, the packaging bag is mechanically installed under the filling gun, and after filling, the packaging bag is mechanically removed from under the filling gun and transferred to the sealing station for sealing. These many steps result in low filling efficiency of cold-curing plywood resin, slow filling speed, and complex filling structure, increasing the production cost of the enterprise. Summary of the Invention

[0007] In view of the problems in the prior art, the purpose of the present invention is to provide a cold-curing plywood resin, its production and processing method, and its application, so as to solve the problems described in the above background art: In the existing cold-curing plywood resin production and processing process, during the process of bagging the prepared cold-curing plywood resin, for the preparation of the packaging bags before filling, it is often necessary to purchase prefabricated packaging bags from a third-party packaging. The price of purchasing prefabricated packaging bags is high, and during the process of filling the cold-curing plywood resin into the packaging bags, the packaging bags are mechanically installed under the filling gun, and after filling, the packaging bags are mechanically removed from under the filling gun and transferred to the sealing station for sealing.

Fold and wrap the plastic sealing film used to prepare the packaging bags into a tube shape and seal the middle line to form a tubular plastic sealing film;

[0013] S5.

[0026] As a preferred technical solution of the present invention, an application of the cold-curing plywood resin is also provided. The cold-curing plywood resin produced and processed in Claim 1 is applied to the surface of the board and left to dry for a certain time. During the curing process, pressure is applied to prevent the generation of pores and ensure the density of the adhesive layer. After the two boards are firmly bonded by the cold-curing plywood resin, it is done.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] First, after the cold-curing plywood resin of the present invention is produced and prepared, the prepared cold-curing plywood resin is transferred to a mixing and stirring cylinder for storage. By setting a rotating stirring rod inside the mixing and stirring cylinder to stir the cold-curing plywood resin inside the mixing and stirring cylinder, the cold-curing plywood resin inside the mixing and stirring cylinder is kept in a flowing state. Before the cold-curing plywood resin is filled into the packaging bag, the plastic film for preparing the packaging bag is automatically folded and wrapped into a tube shape by a machine and sealed at the middle line to form a tubular plastic film. One is that it is convenient for filling, the second is that it can effectively solve the cumbersome operation of repeatedly installing and disassembling the prefabricated packaging bags used in the prior art, effectively improve the filling efficiency, and the filling speed is fast. Third, it can significantly reduce the production and processing costs of enterprises. There is no need to purchase prefabricated packaging bags, and there is no need to set up mechanical devices for bagging and unbagging. The plastic film is automatically folded and wrapped into a tube shape by a machine and sealed at the middle line to form a tubular plastic film. The injection tube extends into the tubular plastic film, and while extruding, the bag is made, realizing bag-making and filling at the same time, with high production efficiency, fast production speed, and low enterprise production costs.

[0029] Second, the cold-curing plywood resin in the mixing and stirring cylinder of the present invention enters the screw conveyor downward through the feed cavity. The extrusion amount is controlled by the conveying servo motor in the screw conveyor. The extruded cold-curing plywood resin generates high-frequency vibration through the vibration motor on the surface of the injection tube, so that the cold-curing plywood resin in the injection tube quickly drops downward and is filled into the tubular plastic film, reducing the adhesion of the resin on the inner wall of the injection tube.

[0030] III. In the present invention, a film winding cylinder is provided at the top of the vertical chassis 4. The plastic sealing film wound on the surface of the film winding cylinder is transferred downward through the reverse rotation of the film feeding roller. The plastic sealing film rewound by the film winding cylinder is guided by the film guiding flow plate. The film guiding pressure strips on both sides of the film guiding flow plate press the two side edges of the plastic sealing film. The plastic sealing film rewound by the film winding cylinder is guided along the film guiding pressure strips, so that the plastic sealing film is wrapped around the film protecting tube through the film guiding flow plate and folded along the outer wall contour of the film protecting tube to form a tubular plastic sealing film. The middle sealing clamping plate assembly that reciprocates in the middle of the middle sealing mechanism heat-seals the edge joint of the tubular plastic sealing film to form a middle sealing line. Since there is too much plastic sealing film accumulated at the folded edge of the tubular plastic sealing film on the outer wall of the film protecting tube, during the middle plastic sealing process of the middle sealing clamping plate assembly, when the edge film pushing block and the constant temperature hot melting sheet I are about to be completely close, through the design of the swing arm frame, the pressing spring, and the film pushing roller, the film pushing roller will push the plastic sealing film on the outer wall of the film protecting tube to move slightly outward to tension the heat-sealing area of the plastic sealing film, which can effectively prevent the plastic sealing film from piling up or stacking near the constant temperature hot melting sheet I during the heat-sealing process, preventing it from being melted and adhered, thereby reducing the situation of unreliable heat-sealing of the middle line of the packaging bag.

[0031] IV. Through the design of the film pushing roller and the resistance wheel in the present invention, when the initial film pushing roller initially contacts the plastic sealing film on the outer wall of the film protecting tube and continues to approach the outer wall of the film protecting tube, through the design of the hinge support I, the film pushing roller will roll outward along the outer wall of the film protecting tube during the extrusion process, and through the design of the resistance wheel, the film pushing roller will generate a rotational resistance during the rolling process, so that the film pushing roller will rotate along the outer wall of the film protecting tube during the initial pushing process and will not push the plastic sealing film, thereby enabling the film pushing roller to tension the plastic sealing film on the outer wall of the film protecting tube. And the foam soft package wrapped on the outer wall of the film pushing roller can more effectively improve the protection of the surface of the plastic sealing film. When the plastic sealing film is tensioned, if the film pushing roller still needs to continue to move at this time, since the plastic sealing film has been tensioned, at this time, the film pushing roller changes from sliding to rolling on the surface of the plastic sealing film on the outer wall of the film protecting tube, thereby driving the resistance wheel to rotate. Therefore, through the design of the film pushing roller and the resistance wheel, it can effectively protect the plastic sealing film from being damaged by the film pushing roller during the process of pushing the plastic sealing film.

[0049] S2. Preparation of the first mixture: The nano-wave-absorbing particle-modified polymer, plasticizer, the dried functional filler, and modified phenolic resin are mixed evenly to obtain the first mixture;

[0050] S3. Preparation of cold-curing plywood resin: The functional catalyst, β-(3,4-epoxycyclohexyl)ethyltriethoxysilane, cashew phenol, ethylene glycol, and the first mixture obtained in step S2 are mixed evenly to obtain the cold-curing plywood resin; the cold-curing plywood resin is a modified phenolic resin adhesive;

[0051] S4. Preparation of packaging bags: The packaging bags required for packaging the cold-curing plywood resin obtained in step S3 are pretreated before packaging the cold-curing plywood resin. The plastic sealing film for preparing the packaging bags is folded and rolled into a tube shape and sealed at the middle line to form a tubular plastic sealing film 10;

[0052] S5. Resin packaging: The cold-curing plywood resin obtained in step S3 is transferred to a mixing and stirring cylinder for storage, and the cold-curing plywood resin in the mixing and stirring cylinder is extruded downward through a glue injection pipe. The extruded cold-curing plywood resin enters the tubular plastic sealing film 10;

[0053] S6. Sealing of packaging bags: The upper and lower ends of the cold-curing plywood resin entering the tubular plastic sealing film 10 in step S4 are sealed tightly. By pressing and clamping from above and below the cold-curing plywood resin entering the tubular plastic sealing film 10, a packaging bag is formed, and the cold-curing plywood resin is sealed in the packaging bag.

[0054] Specifically, in this embodiment, after the cold-curing plywood resin of the present invention is produced and prepared, the prepared cold-curing plywood resin is transferred to the mixing and stirring cylinder 12 for storage. By arranging a rotating stirring rod 1201 inside the mixing and stirring cylinder 12 to stir inside the mixing and stirring cylinder 12, the cold-curing plywood resin inside the mixing and stirring cylinder 12 is kept in a flowing and active state.

The extruded cold-curing plywood resin generates high-frequency vibration through the vibration motor 18 on the surface of the glue injection tube 7, so that the cold-curing plywood resin in the glue injection tube 7 quickly drops downward and is filled into the tubular plastic sealing film 10, reducing the adhesion of the resin on the inner wall of the glue injection tube 7.

With the cooperation of the film guiding pressing strips 20 on both sides of the film guiding flow plate 8 pressing the two side edges of the plastic sealing film 10, the plastic sealing film 10 rewound by the film winding cylinder 11 is guided along the film guiding pressing strips 20, so that the plastic sealing film 10 is wrapped around the protective film tube 13 through the film guiding flow plate 8 and folded along the outer wall contour of the protective film tube 13 to form a tubular plastic sealing film 10. The tubular plastic sealing film 10 is heat-sealed at the edge joint by the middle sealing clamping plate assembly 602 that reciprocally clamps in the middle of the middle sealing mechanism 6 to form a plastic sealing center line.

[0059] Two pressing wheels 5 are provided. The two pressing wheels 5 are arranged side by side on the front face of the vertical chassis 4. And the two pressing wheels 5 rotate in reverse on the front face of the vertical chassis 4. The plastic sealing center line formed by heat sealing passes through the middle of the two pressing wheels 5. By the reverse rotation of the two pressing wheels 5, the plastic sealing center line formed by heat sealing is roll-pressed, effectively improving the plastic sealing tightness of the plastic sealing center line.

[0060] The center-sealing mechanism 6 includes fixed frames 601 symmetrically arranged on the left and right sides of the glue injection tube 7. Each fixed frame 601 on one side is fixedly installed on the front surface of the vertical chassis 4. Guide rod sleeves are symmetrically arranged at the upper and lower ends of each fixed frame 601 on one side. The piston rods of the pneumatic cylinders 604 on the two fixed frames 601 extend towards the glue injection tube 7. The top of the piston rod of each pneumatic cylinder 604 on one side is provided with a center-sealing clamping plate assembly 603. One guide rod 602 is arranged at each of the upper and lower ends of the center-sealing clamping plate assembly 603. The guide rod 602 is slidably connected to the guide rod sleeves at the upper and lower ends of the fixed frame 601, facilitating the reciprocating clamping of the center-sealing clamping plate assembly 603 along the direction of the glue injection tube 7 by the piston rods of the pneumatic cylinders 604 on the left and right sides of the glue injection tube 7.

[0061] The center-sealing clamping plate assembly 603 includes L-shaped support plates 610 arranged on the left and right sides of the glue injection tube 7. An edge film pusher 609 is arranged on the surface of one of the L-shaped support plates 610. The edge film pusher 609 stands upright on the ground at the bottom of the vertical chassis 4. The edge film pusher 609 is of a straight bar structure. The topmost position of the convex surface of the edge film pusher 609 is provided with an arc transition circle 613. A constant-temperature hot melt sheet 611 is provided on the surface of the other L-shaped support plate 610. The surface of the constant-temperature hot melt sheet 308 is provided with an arc-shaped curved surface that fits the edge film pusher 609.

[0062] Specifically, in this embodiment, the present invention prevents scalding the plastic film 10 during the pushing process by providing an edge film pusher 609 on the surface of one of the L-shaped support plates 610. The edge film pusher 609 is a convex structure and does not generate heat. The surface of the constant-temperature hot melt sheet 611 is an arc-shaped curved surface, which can effectively prevent the plastic film 10 from being accidentally melted. The plastic film 10 is safely and reliably processed without melting during the plastic sealing process. The plastic film 10 is pushed by the edge film pusher 609 onto the surface of the constant-temperature hot melt sheet 611 with an arc-shaped depression, so as to achieve hot melting at a preset position on the surface of the plastic film 10. Through the cooperation of the arc transition circle 613 on the surface of the edge film pusher 609 and the arc-shaped curved surface of the constant-temperature hot melt sheet 611, the hot melt plastic sealing process forms a crease-free plastic sealing and fastening on the center line of the formed plastic film 10. Moreover, the arc-shaped bending design of the edge film pusher 609 and the constant-temperature hot melt sheet 611 can improve the clamping force during the hot melting process of the plastic film 10, so that the film pushing roller 606 is safer and more reliable during the process of pushing the plastic film 10 and prevents de-melting.

[0063] At the top of the L-shaped support plate 610 on each side, a hinge support 614 is fixed. A swing arm frame 607 is rotatably connected to the surface of the hinge support 614. At the top of the swing arm frame 607, a film-pushing roller 606 is rotatably connected. A resistance wheel 605 is in rolling contact with the edge of the film-pushing roller 606. A pressing spring 608 is arranged in the middle of the swing arm frame 607. The other end of the pressing spring 608 is fixed to the other side of the L-shaped support plate 610. A foam soft package 612 is wrapped around the outer wall of the film-pushing roller 606.

[0064] Specifically, in this embodiment, the present invention sets a film winding cylinder 11 at the top of the vertical chassis 44. The plastic sealing film 10 wound on the surface of the film winding cylinder 11 is transferred downward through the reverse rotation of the film feeding roller. The plastic sealing film 10 rewound by the film winding cylinder 11 is guided by the film guiding flow plate 8. The film guiding pressure strips 20 on both sides of the film guiding flow plate 8 press the two side edges of the plastic sealing film 10. The plastic sealing film 10 rewound by the film winding cylinder 11 is guided along the film guiding pressure strips 20, so that the plastic sealing film 10 is wrapped around the film protection tube 13 through the film guiding flow plate 8 and folded along the outer wall contour of the film protection tube 13 to form a tubular plastic sealing film 10. The middle sealing mechanism 6 reciprocally clamps the middle sealing plate assembly 602 in the middle to heat-seal the edge joint of the tubular plastic sealing film 10 and form a sealing center line; since there is too much plastic sealing film 10 accumulated at the edge folding part of the tubular plastic sealing film 10 on the outer wall of the film protection tube 13, during the middle sealing process of the middle sealing plate assembly 602 towards the middle, when the edge film pushing block 609 and the constant temperature hot melt sheet 611 are about to be completely tightly attached, through the design of the swing arm frame 607, the pressing spring 608, and the film-pushing roller 606, the film-pushing roller 606 will push the plastic sealing film 10 on the outer wall of the film protection tube 13 to move slightly outward to tighten the heat-sealing area of the plastic sealing film 10, which can effectively prevent the plastic sealing film 10 from piling up or stacking near the constant temperature hot melt sheet 611 during the heat-sealing process, and prevent it from being melted and adhered, thereby reducing the situation that the middle heat-sealing of the packaging bag is not firm and reliable.

[0065] Specifically, in this embodiment, the present invention designs the film-pushing roller 606 and the resistance wheel 605. When the initial film-pushing roller 606 initially contacts the plastic-sealed film 10 on the outer wall of the film-protecting tube 13 and continues to approach the outer wall of the film-protecting tube 13, due to the design of the hinge support 614, the film-pushing roller 606 will roll outward along the outer wall of the film-protecting tube 13 during the extrusion process, and due to the design of the resistance wheel 605, the film-pushing roller 606 will generate rotational resistance during the rolling process, so that the film-pushing roller 606 rotates along the outer wall of the film-protecting tube 13 during the initial pushing of the plastic-sealed film 10, thereby enabling the film-pushing roller 606 to tighten the plastic-sealed film 10 on the outer wall of the film-protecting tube 13. Moreover, the foam soft package 612 wrapped on the outer wall of the film-pushing roller 606 can more effectively improve the protection of the surface of the plastic-sealed film 10. When the plastic-sealed film 10 is tightened, if the film-pushing roller 606 still needs to continue moving at this time, since the plastic-sealed film 10 has been tightened, at this time, the film-pushing roller 606 changes from sliding to rolling on the surface of the plastic-sealed film 10 on the outer wall of the film-protecting tube 13, thereby driving the resistance wheel 605 to rotate. Therefore, through the design of the film-pushing roller 606 and the resistance wheel 605, it can effectively protect the plastic-sealed film 10 from being damaged by the film-pushing roller 606 during the process of pushing the plastic-sealed film 10.

On the surface of one of the movable splints 304, a constant-temperature hot-melt sheet 308 corresponding to the plastic-sealing pushing block 305 is opened.

[0069] Specifically, in the present embodiment, the heat-sealing cutting mechanism 3 of the present invention is provided with two parallel plastic sealing push blocks 305 on the surface of the movable clamping plate 304, and cooperates with the two constant temperature hot melt sheets 308 corresponding to the plastic sealing push blocks 305, so that the two movable clamping plates 304 can be clamped at one time to perform hot melt plastic sealing on the top of the lower packaging bag and the bottom of the upper packaging bag, and through the design of the arc-shaped transition circle 307 and the constant temperature hot melt sheet 308, the hot melt area can be hot-melt sealed without creases during the hot melt plastic sealing process, thereby improving the tightness of the plastic sealing.
