Description

Technical Field

[0001] The present invention belongs to the field of corrugated paper processing equipment, and particularly relates to an intelligent gluing device for corrugated paper processing. Background Art

[0002] Corrugated board is a multi-layer paper bonded board. Due to its light weight and stable structure, it is widely used in product packaging. In the production and processing of corrugated paper, it is necessary to glue multiple layers of raw materials together. An efficient gluing device is an essential equipment for increasing the output of corrugated paper.

[0003] When the existing gluing device glues corrugated paper, it cannot change the gluing width according to the width of the corrugated paper at any time. When gluing corrugated papers of multiple widths, it takes a lot of time to adjust and change the gluing width of the corrugated paper gluing equipment, and it cannot quickly change the gluing width while ensuring uniform gluing. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent gluing device for corrugated paper processing, which is simple to adjust the gluing width and can ensure uniform gluing at different widths.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention includes a transport seat body and a gluing part. The transport seat body includes two bearing beams and a number of transport rollers arranged in a rolling manner between the two bearing beams. The heights of the transport rollers are the same. The gluing part includes a support frame body. A glue input box is fixed on the support frame body. The glue input box extends downward with an output pipe. A rotating pipe is coaxially rotatably arranged on the output pipe. An upper gluing plate is communicated with the rotating pipe. A number of upper gluing heads communicated with the rotating pipe are arranged at the bottom of the upper gluing plate. Steel balls are rotatably arranged at the ends of the upper gluing heads. The upper gluing plate is located above the transport seat body. The transport rollers transport the corrugated board to the bottom of the upper gluing plate. When the steel balls compress and contact the corrugated paper, the upper gluing heads output glue, and the upper gluing plate is rotated to change the gluing width of the upper gluing plate.

[0007] Furthermore, the support frame body includes a middle beam, two transverse moving beams, and two longitudinal moving beams. Support columns are provided at both ends of the transverse moving beams, and the support columns are fixedly arranged on the bearing beam, such that the extending directions of the two transverse moving beams are parallel to the axis of the conveying rollers. The two transverse moving beams are arranged at intervals. The two ends of the middle beam are respectively fixed to the middle parts of the two transverse moving beams. The rubber material input box is fixed to the middle part of the middle beam. The two ends of the two longitudinal moving beams are respectively slidably arranged at the two ends of the two transverse moving beams. The extending direction of the transverse moving beam is perpendicular to the axis of the conveying roller. A baffle plate is fixedly arranged on the lower side of the transverse moving beam. A plurality of vertical rollers for blocking the edges of the corrugated paper are provided at the lower end of the baffle plate. The rotating shafts of the plurality of vertical rollers are perpendicular to the horizontal plane, and the plurality of vertical rollers are arranged in an array along the arrangement direction of the conveying rollers. The vertical rollers are inserted into the intervals between the conveying rollers, and the two transverse moving beams are adjusted to change the distance between the two rows of vertical rollers.

[0008] Furthermore, the rotating tube is located in the middle of the top side of the rubber coating plate. Two traction shafts are rotatably arranged on both sides of the rubber coating plate. The axes of the traction shafts are perpendicular to the horizontal plane. The upper ends of the two traction shafts are respectively slidably arranged along the extending directions of the two longitudinal moving beams. The moving directions of the two pairs of traction shafts are opposite, such that when the two longitudinal moving beams approach each other, the rubber coating plate rotates around the rotating tube.

[0009] Furthermore, rollers are coaxially rotatably arranged at the upper ends of the traction shafts. A chute is arranged in the longitudinal moving beam, and the rollers are rollingly arranged in the chute.

[0010] Furthermore, there are two rubber coating plates. There are two output tubes and they are adjacently connected to the bottom ends of the rubber material input box in pairs. Each output tube is rotatably communicated with a rotating tube. One ends of the two rubber coating plates are respectively communicated with the two rotating tubes. The other ends of the rubber coating plates are rotatably provided with traction shafts. The axes of the traction shafts are perpendicular to the horizontal plane. The upper ends of the two traction shafts are respectively slidably arranged along the extending directions of the two longitudinal moving beams. The moving directions of the two traction shafts are the same, such that when the two longitudinal moving beams approach each other, the two rubber coating plates contract in a V shape.

[0011] Furthermore, rollers are coaxially rotatably arranged at the upper ends of the traction shafts. A chute is arranged in the longitudinal moving beam, and the rollers are rollingly arranged in the chute.

[0012] Furthermore, a stop block is fixed in the middle section of the chute. The stop block is connected with a spring, and the spring is connected with a push block. The push block is located at the central position of the chute. When the rubber coating plate is rotated to be parallel to the conveying roller, the roller abuts against and compresses the push block.

[0013] Furthermore, the pushing direction of the push block is opposite to the conveying direction of the conveying roller.

[0014] The beneficial effects of the present invention are as follows: The corrugated paper is transported to the lower part of the gluing part through the transport seat body, and the surface of the corrugated paper is glued by the gluing part. When the glue application head contacts the corrugated paper, glue can be applied to the corrugated paper. The contact glue application method can avoid the glue being smeared on the transport seat body; when the upper glue plate rotates through the rotating tube and the width covered by the entire upper glue plate in the moving direction of the corrugated paper changes, the density of the glue application remains uniform and not chaotic, ensuring that the corrugated paper after glue application is flatter when pasted, and the overall glue density of the corrugated paper is uniform. This method of adjusting the glue application width is simple and easy to change, and can be suitable for gluing corrugated paper of different widths.

Detailed implementation manners

[0028] As Figures 1 - 5 shown, Embodiment 1 of the present invention provides an intelligent glue application device for corrugated paper processing, including a transport seat body 1 and a glue application part 2. As Figure 1 shown, the transport seat body 1 includes two bearing beams 11 and a number of transport rollers 12 arranged in a rolling manner between the two bearing beams 11. The transport rollers 12 are driven by a motor to rotate and are used to transport the corrugated paper placed on the transport rollers 12 in a single direction. The heights of all the transport rollers 12 are the same to ensure the horizontal movement of the transported corrugated paper. The glue application part 2 includes a support frame body 21. A glue material input box 22 is fixed on the support frame body 21. The glue material input box 22 is connected to a glue material tank for storing glue material and is used to provide glue material for gluing the corrugated paper. As Figure 3 shown, an output pipe 23 extends downward from the glue material input box 22. A rotating pipe 24 is coaxially rotatably arranged on the output pipe 23. A glue application plate 25 is communicated with the rotating pipe 24. A number of glue application heads 26 communicated with the rotating pipe 24 are arranged at the bottom of the glue application plate 25. Referring to Figure 2 , steel balls 261 are rotatably arranged at the ends of the glue application heads 26. The glue application plate 25 is located above the transport seat body 1. The transport rollers 12 transport the corrugated cardboard to the bottom of the glue application plate 25. When the steel balls 261 are compressed and contact the corrugated paper, the glue application heads 26 output glue material. Referring to Figure 4 and Figure 5 , when the glue application plate 25 is rotated, the glue application width of the glue application plate 25 changes.

[0029] In the first embodiment, the corrugated paper is transported to the lower part of the gluing part 2 through the transport seat body 1. The gluing part 2 applies glue to the surface of the corrugated paper. When the glue application head 26 contacts the corrugated paper, glue can be applied to the corrugated paper. The contact gluing method can avoid the glue being smeared on the transport seat body 1. When the upper gluing plate 25 rotates through the rotation of the rotating tube 24, when the width covered by the entire upper gluing plate 25 in the moving direction of the corrugated paper changes, the gluing density still remains uniform and non-disordered, ensuring that the corrugated paper after gluing is flatter when pasted, and the overall glue density of the corrugated paper is uniform. This method of adjusting the gluing width is simple and easy to change, and can be suitable for gluing corrugated paper of different widths.

[0030] In a further solution, referring to Figure 1 and Figure 4 , the support frame body 21 includes a middle beam 211, two transverse moving beams 212 and two longitudinal moving beams 213. Support columns 214 are provided at both ends of the transverse moving beam 212, and the support columns 214 are fixedly arranged on the bearing beam 11, so that the extending directions of the two transverse moving beams 212 are parallel to the axis of the transport roller 12. The two transverse moving beams 212 are arranged at intervals. The two ends of the middle beam 211 are respectively fixed in the middle parts of the two transverse moving beams 212. The glue input box 22 is fixed in the middle part of the middle beam 211. The two ends of the two longitudinal moving beams 213 are respectively slidably arranged at the two ends of the two transverse moving beams 212. The extending direction of the transverse moving beam 212 is perpendicular to the axis of the transport roller 12. A baffle plate 215 is fixedly arranged on the lower side of the transverse moving beam 212. A plurality of vertical rollers 216 for blocking the edge of the corrugated paper are provided at the lower end of the baffle plate 215. The rotating shafts of the plurality of vertical rollers 216 are perpendicular to the horizontal plane. The plurality of vertical rollers 216 are arranged in an array along the arrangement direction of the transport rollers 12. The vertical rollers 216 are inserted into the intervals between the transport rollers 12, and the two transverse moving beams 212 are adjusted to change the distance between the two rows of vertical rollers 216.

[0031] By providing two rows of parallel vertical rollers 216 that can be contracted and expanded, the width between the two rows of vertical rollers 216 can be adjusted according to the width of the corrugated paper. The two rows of vertical rollers 216 block the two sides of the corrugated paper when it moves. When the corrugated paper moves in one direction, the corrugated paper will not be deflected, making the glue path smeared on the corrugated paper straight. After adjusting the gluing width, the maximum gluing width of the upper gluing plate 25 is fixed. The fixation of the vertical rollers 216 in the moving direction of the upper gluing plate 25 can also ensure that the upper gluing plate 25 can glue the entire area of the corrugated paper, avoiding incomplete gluing caused by the offset of the corrugated paper.

[0032] In a further solution, as Figure 3 , Figure 4 and Figure 5, the rotating tube 24 is located in the middle of the top side of the glue-applying plate 25. Two traction shafts 27 are rotatably provided on both sides of the glue-applying plate 25. The axis of the traction shaft 27 is perpendicular to the horizontal plane. A roller 271 is rotatably provided coaxially at the upper end of the traction shaft 27. A chute 2131 is provided in the longitudinal movement beam 213. The roller 271 is arranged to roll in the chute 2131, so that the upper ends of the two traction shafts 27 are respectively arranged to slide along the extending direction of the two longitudinal movement beams 213. The moving directions of the two pairs of traction shafts 27 are opposite. When the two longitudinal movement beams 213 approach each other, the glue-applying plate 25 rotates around the rotating tube 24.

[0033] This structure further connects the expansion and contraction of the two longitudinal movement beams 213 with the rotation of the glue-applying plate 25. When the longitudinal movement beams 213 approach each other, the two rows of vertical rollers 216 approach each other. The traction shafts 27 at both ends of the glue-applying plate 25 move along the two longitudinal movement beams 213 respectively. As Figure 3 shown, after the longitudinal movement beams 213 expand and contract, the width of the two rows of vertical rollers 216 is equal to the width of the corrugated paper. At this time, the glue-applying width of the glue-applying plate 25 is also the width of the corrugated paper. The width of the vertical rollers 216 is fixed, and the glue-applying width is fixed. It can ensure that when the corrugated paper moves along the vertical rollers 216, the glue-applying plate 25 can accurately apply the adhesive on the corrugated paper. The two ends of the glue-applying plate 25 can control the applied glue path to be close to the edge of the corrugated paper, so that after the glue path diffuses subsequently, it can completely cover the edge of the corrugated paper and the surface of the corrugated paper.

[0034] Embodiment 2 of the present invention provides an intelligent glue-applying device for corrugated paper processing. The transport seat body 1 and the support frame body 21 on the glue-applying part 2 are the same as those in Embodiment 1. The difference lies in: Refer to Figures 5 - 10, there are two gluing plates 25. There are two output pipes 23, which are adjacent and communicated at the bottom end of the rubber material input box 22 in pairs. Each output pipe 23 is rotationally communicated with a rotating pipe 24. One ends of the two gluing plates 25 are respectively communicated with the two rotating pipes 24. The other ends of the gluing plates 25 are rotatably provided with traction shafts 27. The axis of the traction shaft 27 is perpendicular to the horizontal plane. The upper end of the traction shaft 27 is coaxially rotatably provided with rollers 271. A chute 2131 is provided in the longitudinal moving beam 213. The rollers 271 are rollingly arranged in the chute 2131. The upper ends of the two traction shafts 27 are respectively slidably arranged along the extending direction of the two longitudinal moving beams 213. A stop block 2132 is fixed in the middle section of the chute 2131. The stop block 2132 is connected with a spring 2133. The spring 2133 is connected with a push block 2134. The push block 2134 is located at the central position of the chute 2131. When the gluing plate 25 is rotated to make the gluing plate 25 parallel to the conveying roller 12, the roller 271 abuts against and compresses the push block 2134. The moving directions of the two traction shafts 27 are the same. The pushing direction of the push block 2134 is opposite to the conveying direction of the conveying roller 12. When the two longitudinal moving beams 213 approach each other, the two gluing plates 25 contract in a V shape.

[0035] Compared with the first embodiment, this structure further improves the structure of the gluing plate 25. The integral gluing plate 25 in a straight line shape is improved to two separated gluing plates 25 in a V shape. During the gluing process of the straight-line gluing plate 25, since one end of it will first contact the corrugated cardboard, the corrugated paper may be warped due to the downward pressure of the gluing head 26, resulting in excessive warping of the corrugated paper and unable to pass through the subsequent gluing head 26. The V-shaped gluing plate 25 structure avoids pressing the edge ends of the corrugated paper. Whether the V-shaped gluing plate 25 opens towards or faces away from the corrugated paper, it can effectively avoid the warping of the corrugated paper: when the V-shaped gluing plate 25 faces away from the corrugated paper, the gluing head 26 in the middle of the gluing plate 25 first contacts the corrugated paper, and the corrugated paper will not be warped. When the V-shaped gluing plate 25 faces the corrugated paper, the gluing heads 26 at both ends of the gluing plate 25 first contact the corrugated paper. Compared with the V-shaped gluing plate 25 facing away from the corrugated paper, it can more effectively keep the corrugated paper flat.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
