Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of top and bottom cover processing equipment, and particularly relates to a paperboard compaction mechanism for top and bottom cover paper box processing. BACKGROUND

[0002] Top and bottom cover refers to a type of box. The cover of the paper box is "top", and the bottom is "bottom", so it is called top and bottom cover. Top and bottom cover is widely used in various gift packaging boxes, shoe boxes, underwear boxes, shirt boxes, mobile phone boxes and various packaging boxes. With the enhancement of people's environmental awareness, the global paper box / carton packaging industry is developing rapidly, and the production capacity has increased significantly. Folded paper boxes have low processing cost, convenient storage and transportation, are suitable for various printing methods, are easy to process, and are particularly beneficial to the promotion and marketing of commodities after surface decoration.

[0003] When the top and bottom cover paper box is produced and processed, the thickness of the paperboard needs to be extruded to improve the overall hardness of the paperboard. In order to prevent the paperboard from being damaged due to excessive extrusion force, the paperboard is not dried before extrusion, so that the paperboard is more easily extruded to a specified thickness. However, if the paperboard cannot be dried in time after extrusion, the thickness of the paperboard will rebound slightly, resulting in that the thickness and hardness of the paperboard cannot meet the specified requirements. In addition, the paperboard extrusion equipment has a single function and cannot be used for paperboard extrusion, drying, paper mounting and embossing. SUMMARY

[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1. In this invention, when the heating tube is pressing the surface of the cardboard, the heating tube can heat and dry the surface of the cardboard after pressing, so that the cardboard after pressing can be quickly shaped and prevent slight expansion after the cardboard is squeezed. This makes the shape and thickness of the cardboard after squeezing more stable, and at the same time, it is convenient for staff to store the cardboard. Furthermore, there is no need for staff to dry the cardboard afterward, making it more convenient to use.

[0018] 2. In this invention, the elastic pushing of the spring enables the heating tube to compact cardboard of different thicknesses, and the pressure on each cardboard surface is the same. During use, the operator can drive the output shaft of the motor to rotate the rotating plate slightly according to the usage situation. When the rotating plate rotates, it can drive the heating tube to move on the surface of the cardboard. The rotation angle of the heating tube and the rotating plate can be adjusted. During use, the operator can adjust the squeezing force of the cardboard according to the usage situation, so that the cardboard can be squeezed into different thicknesses.

[0019] 3. In this invention, when the worker needs to perform paper mounting on the surface of the cardboard, the position of the embossing roller and the heating tube can be flipped by the motor and the rotating plate. When the rotating plate rotates, the fixed rod can be limited to a disconnected position, so that the fixed rod drives the protective shell to rotate. The support rod can provide good support for the protective shell through the limiting hole, and can also limit the rotation angle of the protective shell. When the protective shell rotates, the top plate and the two baffles can block the top and sides of the opposite surfaces of the two protective shells, so that the heating plate at the bottom of the top plate can better heat the inside of the protective shell.

[0020] 4. The rotation of the protective shell in this invention can adjust the distance between the nozzle and the cardboard, making it more convenient and accurate to spray adhesive onto the cardboard surface. The operator can install the unwinding drum with the face paper wound on it onto the embossing roller. The bottom end of the unwinding drum is convenient for contact with the cardboard surface. The face paper on the unwinding drum can be adhered to the cardboard surface by the adhesive on the cardboard surface. When the cardboard moves, the unwinding drum can unwind the face paper on it, so that the face paper adheres to the cardboard surface as the cardboard moves. At the same time, the embossing roller can also squeeze the top of the cardboard through the unwinding drum, so that the face paper adheres better to the cardboard surface and the cardboard is more firmly adhered to the cardboard surface.

[0021] 5. In this invention, several heating plates at the bottom of the top plate can heat the internal space of the two protective shells, so that the hot air inside the two protective shells can directly heat the surface of the cardboard after the face paper is pasted on the top of the cardboard, so that the adhesive can be cured quickly. After the protective shell is rotated, the distance between the top of the placement hole and the conveyor belt is reduced, and the two ends of the mounting plate and the conveyor belt are respectively located in the two placement holes. During use, the contact between the internal space of the protective shell and the outside air can be reduced, and the heat inside the protective shell can be prevented from quickly diffusing to the outside through the placement hole.

[0022] 6、The paperboard in the application is conveyed in the protective shell, the outer wall of the embossing roller directly contacts the surface of the paperboard and extrudes the surface of the paperboard, the embossing roller can compact the paperboard in use, and the arc-shaped grooves on the outer wall of the embossing roller can make the surface of the paperboard have patterns and decorate the surface of the paperboard.

When the protective shell 2 is rotated, the fixed plates 31 on both sides of the top plate 5 abut against the edge corner positions of the opposite surfaces of the two protective shells 2. In use, the two protective shells 2 can better support the top plate 5 through the fixed plates 31, preventing the top plate 5 from moving between the two protective shells 2.

[0037] As a technical optimization scheme of the present application, the end of one of the protective shells 2 away from the placement hole 26 is provided with a placement slot 25 on both sides, the end of the other protective shell 2 close to the placement slot 25 is provided with a baffle 27 on both sides, the baffle 27 is located in the placement slot 25, and the top of the baffle 27 is provided with an arc chamfer away from the edge corner position of the end of the protective shell 2. When the two protective shells 2 are rotated, the baffle 27 can shield the two sides of the opposite surfaces of the two protective shells 2 and seal the inside of the protective shell 2, preventing the heat for heating and drying the paperboard inside the protective shell 2 from being emitted to the outside.

When the paperboard is conveyed on the top of the conveying belt 4, the embossing roller 16 can extrude the surface of the paperboard and form patterns on the surface of the paperboard through the plurality of arc slots on the outer wall.

[0039] As a technical optimization scheme of the present application, the opposite surfaces of the two rotating plates 15 are provided with a connecting slot 18 in the length direction, the two ends of the installation shaft 20 located on the heating pipe 17 are rotatably provided with a connecting block 19, the connecting block 19 is slidably installed in the connecting slot 18, and a spring 21 is installed between the inner top of the connecting slot 18 and the connecting block 19. In use, the spring 21 can push the heating pipe 17 to compact the top of the paperboard through the elasticity of itself, and at the same time, after the paperboard is compacted, the heating pipe 17 can heat the surface of the paperboard, so that the compacted paperboard can be quickly shaped.

[0040] As a technical optimization scheme of the present application, the support plate 12 is provided with a recess 13 on the side close to the inner wall of the protective shell 2, and a motor 14 is installed on the inner wall of the recess 13. The output shaft of the motor 14 penetrates the support plate 12 and is installed on the side surface of the rotating plate 15. In use, the staff can rotate the embossing roller 16 and the heating pipe 17 through the motor 14 and the rotating plate 15, and can adjust the position of the embossing roller 16 and the heating pipe 17.

[0041] As a technical optimization scheme of the application, the top of the mounting plate 1 is provided with a fixing groove 3 in the length direction, the inside of the fixing groove 3 is provided with a conveying belt 4, and the placing hole 26 is located above the conveying belt 4; in use, the staff places the paperboard to be compacted on the top of the conveying belt 4 in sequence, and the paperboard is conveyed through the conveying belt 4, so that the staff does not need to manually place the paperboard in the protective shell 2 in use, and use is more convenient.

[0042] As a technical optimization scheme of the application, the inside top of the placing hole 26 is provided with a connecting plate 10, the bottom of the connecting plate 10 is provided with a plurality of spray heads 11, and the spray heads 11 are located above the conveying belt 4; in use, the connecting plate 10 can be connected with the conveying pipe outside, and the adhesive is sprayed on the surface of the paperboard through the connecting plate 10 and the plurality of spray heads 11, so that the face paper is conveniently adhered and fixed.

[0043] In use, the staff places the paperboard for producing the top and bottom cover paper box to be compacted in sequence from one end of the mounting plate 1 on the top of the conveying belt 4, the conveying belt 4 can convey the paperboard thereon in use, the paperboard moves to the inside of the protective shell 2 in sequence through the placing hole 26, one end of the paperboard can be inserted below the heating pipe 17 from the side bottom end of the heating pipe 17 when the paperboard moves to the inside of the protective shell 2, the top of the paperboard is extruded by the heating pipe, the friction between the top of the paperboard and the top surface of the conveying belt 4 is increased when the top of the paperboard is extruded by the heating pipe 17, and the conveying belt 4 can better drive the paperboard thereon to be conveyed.

[0044] In use, the spring 21 located in the connecting groove 18 can push the connecting block 19 to move downward, the surface of the paperboard can be compacted by the heating pipe 17 through the mounting shaft 20 when the connecting block 19 moves downward, the spring 21 can compact the paperboard of different thicknesses in use, and the pressure degree of each surface of the paperboard is the same. In use, the staff can slightly rotate the rotating plate 15 driven by the output shaft of the motor 14 according to the use condition, the heating pipe 17 moves on the surface of the paperboard when the rotating plate 15 rotates, and the rotating angle of the heating pipe 17 and the rotating plate 15 can be adjusted. When the rotating plate 15 is perpendicular to the top of the paperboard, the overall length of the spring 21 is shortened, the elastic pushing force of the spring 21 on the heating pipe 17 is increased, the extrusion force of the heating pipe 17 on the top of the paperboard is also increased, when the rotating plate 15 is inclined, the overall length of the spring 21 is increased, the pushing force of the spring 21 on the heating pipe 17 is reduced, and the extrusion force of the heating pipe 17 on the surface of the paperboard is also reduced, the staff can adjust the extrusion force of the paperboard according to the use condition in use, and the paperboard can be extruded to different thicknesses.

[0045] In order to prevent the paperboard from being damaged during extrusion, the surface of the paperboard is not dried during extrusion. When the heating pipe 17 compacts the surface of the paperboard, the heating pipe 17 can heat and dry the surface of the paperboard after being pressed, so that the paperboard after being pressed can be quickly shaped, preventing the paperboard from expanding slightly after being extruded, making the shape of the extruded paperboard more stable, facilitating the storage of the paperboard by the staff, and eliminating the need for subsequent drying of the paperboard by the staff, making the use more convenient.

[0046] When the staff needs to paste paper on the surface of the paperboard, the staff can start one of the motors 14, and the output shaft of the motor 14 drives the rotating plate 15 to rotate, and when the rotating plate 15 rotates, the positions of the embossing roller 16 and the heating pipe 17 on the side of the rotating plate 15 are interchanged, so that the bottom end of the embossing roller 16 abuts against the top of the paperboard, and the heating pipe 17 connected with the other motor 14 is still located below. In use, the fixed rod 24 located on the inner wall of the protective shell 2 is located on the top end side of the rotating plate 15, so when the rotating plate 15 rotates, the end of the protective shell 2 close to the placing hole 26 is heavier, so the protective shell 2 can rotate around the connecting rod 7 as the center, and the rotating plate 15 also limits the rotating position and speed of the protective shell 2 when rotating, preventing the end of the protective shell 2 close to the placing hole 26 from colliding with the top of the mounting plate 1 due to excessive rotating speed when the protective shell 2 rotates, and providing better protection for the protective shell 2 and the mounting plate 1 in use.

[0047] When the protective shell 2 rotates, the support rod 8 located on the side of the mounting plate 1 can move to the inside of the limiting hole 9 along with the rotation of the protective shell 2, and until the support rod 8 abuts against the inner wall of the limiting hole 9. In use, the two ends of the mounting plate 1 are located in the placing holes 26 on the two protective shells 2, respectively. The plurality of nozzles 11 are connected with the conveying pipe outside through the connecting plate 10, and when the protective shell 2 rotates, the connecting plate 10 and the nozzles 11 can move towards the mounting plate 1, and when the support rod 8 abuts against the inner wall of the limiting hole 9, the plurality of nozzles 11 are located above the conveying belt 4. In use, the distance between the nozzles 11 and the paperboard can be adjusted, and the plurality of nozzles 11 can spray adhesive on the surface of the paperboard through the conveying pipe and the connecting plate 10, facilitating the staff to paste the paper, and the distance between the nozzles 11 and the surface of the paperboard is close, so the nozzles 11 will not spray adhesive on the mounting plate 1 when spraying, making the spraying of the adhesive more accurate.

[0048] When in use, the staff can install the unwinding drum with the surface paper on one of the lower embossing rollers 16, and the arc-shaped grooves on the embossing roller 16 can better limit the position of the unwinding drum and increase the friction between the embossing roller 16 and the inner wall of the unwinding drum. When the two protective shells 2 rotate away from each other, the top end of the protective shell 2 can pull the sliding block 23, so that the sliding block 23 slides in the sliding groove 22. The sliding block 23 is rotationally installed on the limiting plate 28 on both sides of the top plate 5, so when the sliding block 23 moves with the rotation of the protective shell 2 after abutting against the inner wall of the sliding groove 22, the sliding block 23 can pull the limiting plate 28 on both sides of the top plate 5. In use, the two protective shells 2 pull the two sides of the top plate 5, so that the top plate 5 is located above the two protective shells 2 after the rotation of the protective shell 2, and the fixed plate 31 on both sides of the top plate 5 abuts against the corner position of the protective shell 2 close to the top plate 5. In use, the top plate 5 can shield the upper side of the opposite surface of the two protective shells 2, and the top plate 5 can better limit the top end of the protective shell 2 through the limiting plate 28, so that the protective shell 2 is more stable in use.

[0049] When the two protective shells 2 rotate, the baffle 27 on one of the protective shells 2 can rotate in the placing groove 25 on the other protective shell 2, so that the baffle 27 can shield the opposite surfaces of the two protective shells 2. In use, the staff can install the unwinding drum with the surface paper on the embossing roller 16, and the arc-shaped grooves on the embossing roller 16 can better limit the inner wall of the unwinding drum, so that the unwinding drum is more stable during installation.

[0050] When the paperboard moves into the protective shell 2, the plurality of nozzles 11 can uniformly spray the adhesive on the surface of the paperboard. When the paperboard moves into the protective shell 2, the bottom end of the unwinding drum abuts against the surface of the paperboard, and the surface paper on the unwinding drum can be pasted on the surface of the paperboard through the adhesive on the surface of the paperboard. With the movement of the paperboard, the unwinding drum and the embossing roller 16 also rotate on the top of the paperboard. When the unwinding drum rotates, the surface paper on the unwinding drum can be unwound, so that the surface paper is pasted on the surface of the paperboard with the movement of the paperboard. At the same time, when the embossing roller 16 pastes the surface paper on the surface of the paperboard through the unwinding drum, the embossing roller 16 can also press the top of the paperboard through the unwinding drum, so that the surface paper is better pasted on the surface of the paperboard, and the paperboard is more firmly pasted on the surface of the paperboard.

[0051] When the surface paper is pasted on the surface of the paperboard, the several heating plates 30 at the bottom of the top plate 5 can heat the internal space of the two protective shells 2, so that the hot air in the internal space of the two protective shells 2 directly heats the surface of the paperboard after the surface paper is pasted on the top of the paperboard, so that the adhesive is quickly solidified. When the paperboard is moved out of the protective shell 2, the staff can cut the surface paper connected between the adjacent paperboards. After the protective shell 2 is rotated, the distance between the top of the placement hole 26 and the conveying belt 4 is reduced, and the two ends of the mounting plate 1 and the conveying belt 4 are located in the two placement holes 26 respectively. In use, the contact between the internal space of the protective shell 2 and the external air can be reduced, and the heat in the internal space of the protective shell 2 can be prevented from quickly spreading to the outside through the placement hole 26.

[0052] In use, the staff can install the unwinding drum according to the use condition, so that the outer wall of the embossing roller 16 directly contacts the surface of the paperboard and extrudes the surface of the paperboard. In use, the embossing roller 16 can compact the paperboard, and the several arc-shaped grooves on the outer wall of the embossing roller 16 can make the surface of the paperboard have patterns and decorate the surface of the paperboard. After the staff completes the embossing and pasting of the surface paper on the surface of the paperboard, the staff can start the motor 14 again, so that the motor 14 drives the embossing roller 16 to move to the upper position again through the rotating plate 15, and the heating roller 17 abuts against the surface of the paperboard. When the rotating plate 15 rotates, the rotating plate 15 can drive the protective shell 2 to rotate through the fixed rod 24, so that the opposite surfaces of the two protective shells 2 abut against each other. Since the top end of the protective shell 2 is always located at the bottom of the fixed plate 31, when the protective shell 2 rotates, the top end of the protective shell 2 can slide along the bottom of the fixed plate 31, so that the opposite surfaces of the two protective shells 2 abut against each other, and the top plate 5 is located at the top of the protective shell 2.

[0053] In use, the staff can rotate one of the protective shells 2 or rotate the two protective shells 2 according to the use condition. When one of the protective shells 2 rotates, the embossing roller 16 and the unwinding drum on one of the rotating plates 15 abut against the top of the paperboard, and the heating pipe 17 on the other rotating plate 15 contacts the surface of the paperboard on which the surface paper is pasted, so as to extrude and heat the surface paper. When the two protective shells 2 rotate simultaneously, the two embossing rollers 16 contact the paperboard simultaneously, one of the embossing rollers 16 is provided with the unwinding drum, and the other embossing roller 16 can emboss the surface of the paperboard on which the surface paper is pasted. In use, the staff can adjust the positions of the protective shells 2, the embossing rollers 16 and the heating pipes 17 according to the use condition, so as to achieve various processing effects on the paperboard.

[0054] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
