Therefore, in the prior art, multiple layers of cardboard are bonded together to form a composite cardboard to meet the transportation requirements.

However, when the adhesive is applied to the surface of the cardboard, the adhesive cannot be more evenly bonded to the surface of the cardboard, and thus the synthesized composite cardboard is prone to edge warping or air pockets, affecting the actual use effect of the composite cardboard.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0099] Please refer to Figure 1-14 , the present invention provides a technical solution:

[0100] A cardboard production device, comprising:

[0101] A trough body 1, in which a tray 3 is slidably inserted into the upper opening;

[0102] A transverse driving mechanism 5 is fixedly assembled on the upper edge of the trough body 1, and a cardboard gluing member 6 is fixedly assembled on its movable part;

[0103] A heating electrothermal gluing roller 64 is rotatably arranged at the lower end of the cardboard gluing member 6, and it is arranged along the width direction of the tray 3;

[0104] A lifting driving structure 4 is longitudinally assembled on the side wall of the trough body 1, and its movable part is fixedly connected to the tray 3;

[0105] A ferromagnetic strip-shaped cover 15 is sleeved and magnetically adsorbed at the lower end of the cardboard gluing member 6, and its lower end is an arc surface;

[0106] The transverse driving mechanism 5 drives the electrothermal gluing roller 64 to move horizontally to apply glue, and after the ferromagnetic strip-shaped cover 15 is sleeved at the lower end of the cardboard gluing member 6, it is driven by the transverse driving mechanism 5 to move horizontally to scrape and press the glued cardboard;

[0107] An ultrasonic oscillation structure is assembled on the bottom surface of the tray 3.

[0108] Specifically in this embodiment, the lifting driving structure 4 is electrically connected to a PIC controller 12. The PIC controller 12 is used to control the lifting driving structure 4 to drive the tray 3 to lift, so that after the electrothermal gluing roller 64 magnetically adsorbs the ferromagnetic strip-shaped cover 15, the lower end of the ferromagnetic strip-shaped cover 15 just presses on the upper surface of the cardboard to be pressed and formed, and the ferromagnetic strip-shaped cover 15 scrapes and forms the cardboard to be pressed and formed as it is driven by the transverse driving mechanism 5;

[0109] Furthermore, the cardboard gluing member 6 can be used for gluing during cardboard pasting. After gluing, an iron strip-shaped cover 15 is magnetically adsorbed at the lower end of the cardboard gluing member 6. By using the moving cardboard gluing member 6 and the iron strip-shaped cover 15 to scrape and press the pasted cardboard into shape, the cardboard gluing member 6 can be used for both the gluing and shaping processes, eliminating most of the devices in the shaping process and reducing the space occupied by the devices.

[0110] More specifically, the length of the electrothermal gluing roller 64 is the same as the width of the cardboard to be glued, ensuring full gluing of the cardboard during the moving process. The ultrasonic oscillation structure uses the oscillation characteristics of ultrasonic waves to oscillate and level the applied glue, enabling the glue to enter the bottom surface of the grooves formed by cardboard embossing.

[0111] It can be understood that the iron strip-shaped cover 15 is fixed to the lower end of the cardboard gluing member 6 by magnetic adsorption. When it needs to be disassembled, the iron strip-shaped cover 15 is pulled downward to overcome the magnetic suction force to complete the disassembly. During installation, the reverse operation can be performed. The lower end arc surface of the iron strip-shaped cover 15 just presses and fits with the formed cardboard, and the arc surface is smooth, avoiding abrasion of the cardboard surface during the scraping and pressing process.

[0112] In some embodiments, the cardboard gluing member 6 includes:

[0113] A cavity plate body 61, whose upper end is fixedly connected to the movable part of the transverse driving mechanism 5 through ear plates and bolts;

[0114] The cross-section of the cavity plate body 61 is a cone with a larger upper part and a smaller lower part, and a honeycomb-shaped flow guide plate 63 is fixed inside the cavity of the cavity plate body 61;

[0115] The shunt holes of the honeycomb-shaped flow guide plate 63 gradually decrease in diameter from top to bottom;

[0116] The electrothermal gluing roller 64 is rotationally assembled at the lower end of the cavity plate body 61, and the upper end of the electrothermal gluing roller 64 is blocked at the lower end opening of the cavity plate body 61;

[0117] Arc-shaped grooves are evenly formed on the outer wall of the electrothermal gluing roller 64;

[0118] A magnetic block 68 is embedded and assembled at the lower end of the outer wall of the cavity plate body 61;

[0119] A transverse pipe 65 is fixedly arranged along the length direction on the top surface of the cavity plate body 61, and spray heads 66 are fixedly connected and communicated evenly along the length direction on its bottom surface;

[0120] The lower end of the spray head 66 penetrates through the top surface of the cavity plate body 61 and extends to the upper end of the inner cavity;

[0121] Both ends of the transverse pipe 65 are designed to be sealed, and a liquid inlet pipe 67 is fixedly connected and communicated in the middle of the top surface of the transverse pipe 65;

[0122] An electrothermal pipe 62 is embedded and coiled inside the side wall of the cavity plate body 61.

[0123] Specifically in this embodiment, the honeycomb-shaped flow guide plate 63 is longitudinally provided with diversion holes to disperse the glue entering from top to bottom; an opening is provided at the lower end of the cavity plate body 61 for discharging the glue. The electrothermal glue applicator roller 64 is rotatably assembled at the opening at the lower end of the cavity plate body 61 and seals the opening. The electrothermal glue applicator roller 64 is driven to move horizontally along with the cavity plate body 61. The bottom surface of the electrothermal glue applicator roller 64 is in contact with the cardboard to be glued and rotates by the action of friction. During the rotation of the electrothermal glue applicator roller 64, the glue is taken out through the arc-shaped groove and applied to the cardboard.

[0124] Furthermore, the outer wall of the electrothermal glue applicator roller 64 is made of an elastic material. During the rolling process in contact with the cardboard, it is squeezed and deformed to release the glue in the arc-shaped groove, and it is evenly applied to the surface of the cardboard as the electrothermal glue applicator roller 64 rolls. Glue is supplied into the upper end of the cavity plate body 61 through the liquid inlet pipe 67. The glue is evenly distributed on the top surface of the honeycomb-shaped flow guide plate 63 through the horizontal pipe 65 and the nozzle 66. The aperture of the diversion holes of the honeycomb-shaped flow guide plate 63 gradually decreases from top to bottom, further evenly dispersing the glue, so that the glue falling on the upper end of the electrothermal glue applicator roller 64 is evenly distributed.

[0125] More specifically, the glue used in this embodiment is specifically hot melt glue, which solidifies after being cooled and also solidifies quickly when being squeezed after pasting an object. The liquid inlet pipe 67, the horizontal pipe 65, and the nozzle 66 for supplying the glue need to be in a high-temperature environment to prevent the glue from solidifying inside. The method of winding an energized resistance wire on the outer wall of the pipeline can be adopted.

[0126] It can be understood that the electrothermal tube 62 wound around the inner wall of the cavity plate body 61 generates heat after being energized, which is used to heat the glue flowing in the honeycomb-shaped flow guide plate 63 to prevent the glue from solidifying due to too low temperature.

[0127] In some embodiments, the ultrasonic oscillation structure includes:

[0128] An ultrasonic generator 11 and an ultrasonic vibrator 10, and the ultrasonic vibrator 10 is electrically connected to the ultrasonic generator 11;

[0129] Both the ultrasonic generator 11 and the ultrasonic vibrator 10 are direct applications of existing technologies. The ultrasonic vibrators 10 are evenly fixed on the bottom surface of the pallet 3. The evenly distributed ultrasonic vibrators 10 are provided with high-frequency alternating current signals through one or more ultrasonic generators 11, generating high-frequency vibrations at the ultrasonic vibrators 10, and transmitting through the pallet 3 to oscillate the glue applied on the cardboard, so that the glue is dispersed and flows on the cardboard, improving the evenness of the glue application, and enabling the glue to enter the bottom surface of the grooves formed by printing on the cardboard and into the surface micropores of the cardboard.

[0130] In some embodiments, the lateral driving mechanism 5 includes:

[0131] The upright columns 51, and the number thereof is four; the four upright columns 51 are respectively vertically and fixedly assembled at the four corners of the upper edge of the tank body 1;

[0132] A first screw rod 53 is horizontally and rotatably assembled between the upright columns 51 on both sides of the front end;

[0133] A first driving motor 52 is fixedly assembled on the outer wall of the upright column 51 on one side of the front end, and the output end thereof is fixedly connected to the end of the first screw rod 53;

[0134] A round rod 54 is horizontally and rotatably assembled between the upright columns 51 on both sides of the rear end;

[0135] A first connecting block 55 is screwed on the outer wall of the first screw rod 53, and the first connecting block 55 is slidably sleeved on the outer wall of the round rod 54;

[0136] The front and rear first connecting blocks 55 are the movable parts of the horizontal driving mechanism 5.

[0137] Specifically in this embodiment, the first determining motor 52 is specifically a servo motor, which is connected to an external power supply to drive the first screw rod 53 to rotate at a constant speed. The rotation of the first screw rod 53 drives the front first connecting block 55 to drive the cardboard gluing member 6 and the rear first connecting block 55 to move left and right along the round rod 54;

[0138] Furthermore, the round rod 54 plays a guiding role, so that the rotation of the first screw rod 53 drives the front first connecting block 55 to drive the cardboard gluing member 6 to move horizontally.

[0139] In some embodiments, the lifting drive structure 4 includes:

[0140] A longitudinal window 41, which is opened on the side wall of the tank body 1;

[0141] A second screw rod 43 is longitudinally and rotatably assembled in the longitudinal window 41;

[0142] A second driving motor 42 is fixedly assembled on the upper edge of the tank body 1 corresponding to the second screw rod 43, and the output end thereof is fixedly connected to the upper end of the second screw rod 43;

[0143] A second connecting block 44 is screwed on the outer wall of the second screw rod 43, and it is slidably assembled in the longitudinal window 41;

[0144] The second connecting block 44 is the movable part of the lifting drive structure 4.

[0145] Specifically in this embodiment, the second driving motor 42 is specifically a servo motor, which is connected to an external power supply to drive the second screw rod 43 to rotate at a constant speed. The second screw rod 43 drives the second connecting block 44 screwed thereon to slide up and down along the longitudinal window 41, and drives the support plate 3 to lift through the second connecting block 44;

[0146] Further, the rear wall of the pallet 3 is fixedly connected to the rear slider 13. A chute 14 is longitudinally formed in the rear side of the upper edge of the groove body 1 corresponding to the slider 13. The slider 13 is slidably assembled in the chute 14 to guide the up and down movement of the pallet 3 and improve the stability of the pallet 3 during up and down movement.

[0147] In some embodiments, the electrothermal coating roller 64 includes:

[0148] A roller body 641, in the middle of one end face of which a blind hole is formed, and a columnar charging power supply 643 is inserted into the blind hole;

[0149] A top cover 645 is screwed to the end face of the roller body 641 where the blind hole is formed;

[0150] Third screw rods 646 are rotatably connected to the middle of the end face of the side of the roller body 641 where no blind hole is formed and the outer end face of the top cover 645;

[0151] The outer ends of the third screw rods 646 are fixedly connected to the end face on the same side as the lower opening of the cavity plate body 61 through nuts;

[0152] First disassembly windows 16 are formed in the end face at the lower opening of the cavity plate body 61 corresponding to the third screw rods 646;

[0153] A resistance wire 644 is embedded and assembled in the inner wall circumference of the roller body 641, and the resistance wires 644 are connected in parallel and electrically connected to the columnar charging power supply 643;

[0154] A silica gel layer 642 is pasted on the outer wall of the roller body 641, and its outer wall is attached to the lower opening of the cavity plate body 61.

[0155] Specifically in this embodiment, the columnar charging power supply 643 is specifically a cylindrical storage battery. The columnar charging power supply 643 can be charged and switched by unscrewing the top cover 645; during use, the third screw rods 646 on the end face of the side of the roller body 641 where no blind hole is formed and the outer end face of the top cover 645 are inserted into the first disassembly windows 16 on the same side, so that the third screw rods 646 are located at the uppermost end of the first disassembly windows 16. Then, nuts are screwed onto the outer ends of the third screw rods 646 until they abut against the outer wall of the cavity plate body 61, and the roller body 641 and the top cover 645 are clamped and fixed to the lower end of the cavity plate body 61 by using the nuts. During disassembly, the nuts are unscrewed, and the third screw rods 646 can be taken out from the first disassembly windows 16 on the same side to complete the simultaneous disassembly of the roller body 641 and the top cover 645;

[0156] Further, the resistance wire 644 in the roller body 641 is independently powered by the columnar charging power supply 643, and the resistance wire 644 heats the roller body 641 to prevent the glue on its surface from solidifying;

[0157] More specifically, the silica gel layer 642 on the surface of the roller body 641 is made of an elastic material and deforms after being squeezed. The arc-shaped grooves formed on the surface of the roller body 641 are located on the outer wall of the silica gel layer 642, and the stored glue is released after being squeezed.

[0158] In some embodiments, the iron strip-shaped cover 15 includes:

[0159] A strip-shaped cover main body 151, the lower end surface of which is an arc surface;

[0160] On both side end faces of the strip-shaped cover main body 151, second disassembly windows 152 are provided corresponding to the end connection structure of the electrothermal glue applicator roller 64.

[0161] Specifically in this embodiment, the position of the second disassembly window 152 corresponds to the nut screwed on the outer wall of the third screw 646. The width of the second disassembly window 152 is greater than or equal to the span after the nut is screwed, so that the nut will not hinder the installation of the strip-shaped cover main body 151;

[0162] It can be understood that the strip-shaped cover main body 151 is made of iron and can be adsorbed and fixed to the magnet 68 on the outer wall of the cavity plate body 61. When disassembly is required, the strip-shaped cover main body 151 is pulled downward to overcome the magnetic attraction force to complete the disassembly, and the reverse operation can be performed during installation.

[0163] In some embodiments, a hot air mechanism 7 is detachably fixedly assembled in the middle of the upper edge of the groove body 1, and it includes:

[0164] An L-shaped frame 71, the longitudinal part of which is detachably assembled at the rear side of the upper edge of the groove body 1;

[0165] The transverse part of the L-shaped frame 71 is located above the middle of the support plate 3, and a hot air structure 73 is assembled on the transverse part of the L-shaped frame 71;

[0166] The output end of the hot air structure 73 penetrates through the transverse part of the L-shaped frame 71 and faces the support plate 3;

[0167] L-shaped reinforcing ribs 72 are integrally formed on the outer wall of the L-shaped frame 71 evenly;

[0168] On the left and right sides at the front end of the transverse part of the L-shaped frame 71, L-shaped support rods 74 are fixedly connected, and the lower ends of the L-shaped support rods 74 are detachably assembled at the front side of the upper edge of the groove body 1.

[0169] Specifically in this embodiment, the hot air generated by the hot air structure 73 blows downward on the cardboard, which is used to prevent the glue from solidifying too quickly due to low temperature during the glue application process;

[0170] The hot air structure 73 has the same principle as a hot air blower, with a fan blowing air downward and heating the incoming cold air. The heating is carried out by a coiled electric heating tube or other heating devices to form hot air blowing towards the cardboard;

[0171] Further, both the L-shaped frame 71 and the L-shaped support rod 74 serve as support structures for the installation of the hot air structure 73. The L-shaped frame 71 and the L-shaped support rod 74 are installed on the upper edge of the trough body 1 through ear plates and bolts and can be disassembled when needed.

[0172] It can be understood that the L-shaped reinforcing rib 72 is used to enhance the mechanical strength of the L-shaped frame 71 as a bracket.

[0173] In some embodiments, it includes a cardboard embossing mechanism 9 and a cardboard 8.

[0174] The cardboard embossing mechanism 9 includes:

[0175] Side plates 91, with two of them distributed in parallel front and back;

[0176] A cardboard printing structure 92 is fixedly assembled between the front and rear side plates 91, and it includes:

[0177] A printing roller 921, on the outer wall of which strip-shaped protrusions 922 are integrally formed uniformly along the length direction;

[0178] The printing roller 921 is rotatably assembled between the front and rear side plates 91;

[0179] The distance between adjacent strip-shaped protrusions 922 is the same as the width of the strip-shaped protrusions 922;

[0180] A third driving motor 923 is fixedly assembled on the outer wall of one side plate 91, and its output end penetrates through the side plate 91 and is fixedly connected to the same-side rotating shaft of the printing roller 921;

[0181] A round roller 924 is rotatably assembled between the front and rear side plates 91, and it is located below the printing roller 921;

[0182] The single-layer structure of the cardboard 8 passes through the gap between the round roller 924 and the printing roller 921 and is printed on one side.

[0183] Specifically in this embodiment, the third driving motor 923 is specifically a servo motor. After being powered on, it drives the printing roller 921 to rotate at a constant speed. The side of the single-layer cardboard that needs to be printed faces the printing roller 921, and the side facing the round roller 924 does not need to be printed;

[0184] Further, the upper cardboard 82 and the lower cardboard 81 are printed on one side through the gap between the round roller 924 and the printing roller 921. The printed sides of the upper cardboard 82 and the lower cardboard 81 are attached to each other, so that the protrusions and grooves formed by printing are engaged with each other, increasing the contact area between the attachment surfaces of the upper cardboard 82 and the lower cardboard 81;

[0185] More specifically, glue flows into the grooves generated by printing under the oscillation of the ultrasonic vibrator 10, ensuring that there is glue in the grooves generated by printing and making the glue evenly distributed.

[0186] In some embodiments, the cardboard 8 includes:

[0187] an upper cardboard 82 and a lower cardboard 81;

[0188] The bottom surface of the upper cardboard 82 is uniformly pressed with first strip-shaped grooves 83, and first strip-shaped protrusions 86 are formed between adjacent first strip-shaped grooves 83;

[0189] The top surface of the lower cardboard 81 is uniformly pressed with second strip-shaped grooves 85, and second strip-shaped protrusions 84 are formed between adjacent second strip-shaped grooves 85;

[0190] The first strip-shaped protrusion 86 is inserted into the corresponding second strip-shaped groove 85;

[0191] The second strip-shaped protrusion 84 is inserted into the corresponding first strip-shaped groove 83;

[0192] Hot melt adhesive is coated between the first strip-shaped protrusion 86 and the second strip-shaped groove 85, and between the second strip-shaped protrusion 84 and the first strip-shaped groove 83.

[0193] Specifically in this embodiment, the grooves and protrusions are uniformly strip-shaped, and the grooves and protrusions on the upper cardboard 82 and the lower cardboard 81 can be completely engaged. After applying glue on the upper surface of the lower cardboard 81, cover the upper cardboard 82 on the lower cardboard 81 and gently press to make the grooves and protrusions between the two completely engaged. Use the lower end of the horizontally moving iron strip-shaped cover 15 to scrape and press, so that the hot melt adhesive between the upper cardboard 82 and the lower cardboard 81 is cured and formed. The hot air structure 73 is closed during the forming stage;

[0194] Furthermore, after the upper cardboard 82 and the lower cardboard 81 are formed, use a cutting tool to cut off the single-layer part at the edge of the formed cardboard, and divide the formed cardboard as needed.

[0195] In some embodiments, both the cardboard embossing mechanism 9 and the tank body 1 are fixed to the upper end of the mounting base plate 2 in a detachable fixing manner. The height of the cardboard printing structure 92 on the cardboard embossing mechanism 9 is higher than the height of the supporting plate 3 on the tank body 1. The cardboard embossing mechanism 9 is located on one side of the end of the tank body 1. After the cardboard embossing mechanism 9 completes the printing of a single-layer cardboard, this single-layer cardboard can be conveniently transferred to the supporting plate 3 at a lower place beside.
