Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, and in particular to a corrugated cardboard processing equipment. Background Technology

[0002] Conventional corrugated cardboard production requires creasing to facilitate subsequent folding into corrugated cardboard boxes. Of course, corrugated cardboard production technology has a long history, with a wide variety of mechanical equipment and mechanisms.

[0003] For example, Chinese Patent Application No. 201220338222.0 discloses a creasing device for a corrugated cardboard machine with pre-pressing. This device is installed at the front end of the longitudinal creasing machine or the transverse slitting machine on the corrugated cardboard machine. It mainly includes a set of creasing devices, which are mounted on the machine frame and consist of a pressure roller and a support roller. A pressure roller with a groove is installed on the pressure roller, and a support roller with a groove is installed on the support roller. A pre-pressing roller is installed at the front end of the creasing device, a pressure roller is installed on the pre-pressing roller, and a pad roller is installed below the pre-pressing roller.

[0004] For example, Chinese Patent Application No. 201910056112.1 discloses a high-precision creasing machine for corrugated paper production, including a first base frame, a second base frame, a conveying mechanism, a third base frame, a heating machine, a first clamping mechanism, etc.; the conveying mechanism is installed on the first base frame. This invention enables creasing of corrugated paper of various thicknesses and allows adjustment of the creasing distance.

[0005] The existing equipment is not optimized for creasing, and the uniformity of the creasing is not very high. There are undulations, which will result in insufficient uniformity of the structure. This will cause uneven force during subsequent folding, affecting the area around the creasing and making it prone to wrinkles or damage. This will affect both the smoothness of folding and the structural stability of the corrugated cardboard box. Utility Model Content

[0006] The purpose of this invention is to provide a processing equipment for corrugated cardboard with good creasing effect.

[0007] The above-mentioned objective of this utility model is achieved through the following technical solution: a corrugated cardboard processing equipment, comprising an output guide roller group for outputting corrugated cardboard forward, a pulling mechanism in front of the output roller group for pulling the corrugated cardboard forward, a support platform for supporting and sliding the corrugated cardboard, and a creasing mechanism above the support platform for creasing the corrugated cardboard. The creasing mechanism includes a first creasing component for creasing the left and right sides of the corrugated cardboard front and back, and a second creasing component for creasing the left and right sides of the corrugated cardboard at intervals.

[0008] As a preferred embodiment of the present invention, the first indentation assembly includes a left first rolling roller mounting bracket and a right first rolling roller mounting bracket that are movable up and down and are spaced apart, as well as a first left rolling roller with an axial direction in the left-right direction mounted on the left first rolling roller mounting bracket and a first right rolling roller with an axial direction in the left-right direction mounted on the right first rolling roller mounting bracket.

[0009] As a preferred embodiment of the present invention, the second indentation assembly includes multiple sets of second rolling groups arranged at intervals in the front and back. Each second rolling group includes a second rolling wheel mounting frame that moves up, down, left, and right, and a second rolling wheel with an axial direction in the front and back direction that is mounted and connected on the second rolling wheel mounting frame.

[0010] As a preferred embodiment of this invention, the initial position of the second rolling wheel mounting bracket is on the left or right side of the support platform.

[0011] As a preferred embodiment of this invention, the upper surface of the support platform is a smooth steel surface.

[0012] As a preferred embodiment of the present invention, the pulling mechanism includes a front pulling component for pulling the corrugated cardboard forward and a rear positioning component for pressing and positioning the corrugated cardboard, which are distributed front and rear above the support platform.

[0013] As a preferred embodiment of this utility model, the front traction assembly includes a traction bracket that can move back and forth and up and down, and a traction vacuum suction cup that is installed and connected to the traction bracket and can suck up the upper surface of the corrugated cardboard downwards.

[0014] As a preferred embodiment of the present invention, the rear positioning component includes a positioning bracket that can move up and down, and a positioning vacuum suction cup that is installed and connected to the positioning bracket and can be downwardly attracted to the upper surface of the corrugated cardboard.

[0015] As a preferred embodiment of this invention, both the traction vacuum suction cup and the positioning vacuum suction cup are rectangular horn-shaped.

[0016] As a preferred embodiment of this invention, the output guide roller assembly includes an upper guide roller and a lower guide roller that are adjustable up and down and are positioned vertically.

[0017] The beneficial effects of this utility model are as follows: The processing equipment in this application, through the traction mechanism and related design, makes the corrugated cardboard flatter during the creasing process, and the creasing effect is more thorough and more uniform, which can produce high-quality creasing corrugated cardboard and facilitates folding to form high-quality packaging boxes.

[0018] In addition, the longitudinal and transverse indentation processes have good continuity and can be completed on a single production line, ensuring efficiency. Attached Figure Description

[0019] Figure 1 This is a three-dimensional structural diagram of the corrugated cardboard processing equipment in the embodiment. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0022] Examples, such as Figure 1 As shown, a corrugated cardboard processing device includes an output guide roller assembly for outputting corrugated cardboard forward, a pulling mechanism in front of the output roller assembly for pulling the corrugated cardboard forward, a support plate 1 for supporting and sliding the corrugated cardboard, and a creasing mechanism above the support plate 1 for creasing the corrugated cardboard. The output guide roller assembly mainly outputs the original hot-pressed corrugated cardboard. The output guide roller assembly only needs to be in contact with the original corrugated cardboard at its upper and lower limits to allow the corrugated cardboard to be output; it does not need to be pressed very tightly because the power output is achieved by the pulling mechanism. The hot-pressing process of corrugated cardboard is relatively slow, while the creasing processing device of this application is significantly faster. That is, a hot-pressing production machine for corrugated cardboard cannot keep up with a creasing processing machine of this application. Therefore, one creasing processing equipment of this application can be equipped with several hot pressing production equipment. The hot pressing production equipment is used to hot press and bond rolls of different layers of paper together. The original corrugated cardboard produced by hot pressing is the length of one roll of one type of paper, which is generally tens to hundreds of meters long. For example, one hot pressing equipment can produce one 100-meter corrugated cardboard sheet at a time, and three equipment can produce three 100-meter corrugated cardboard sheets at the same time. One creasing equipment can also be controlled at three times the speed of hot pressing. That is, in the same amount of time, the creasing equipment can complete the creasing operation of three 100-meter corrugated cardboard sheets.

[0023] The support platform 1 is designed to facilitate the placement and movement of the corrugated cardboard. A pulling mechanism pulls the corrugated cardboard forward to complete the longitudinal creasing, then pulls it to a designated position for lateral creasing. Therefore, the creasing mechanism includes a first creasing component that creasing the left and right sides of the corrugated cardboard longitudinally and a second creasing component that creasing the corrugated cardboard laterally at intervals. The first creasing component performs longitudinal creasing, and the second creasing component performs lateral creasing. The first creasing component can complete the creasing of a specified length of corrugated cardboard in one go, which can be done during the pulling process. Multiple second creasing components can simultaneously perform lateral creasing after the first creasing component has completed the creasing of a long section of corrugated cardboard. The creasing efficiency can be improved by proceeding from front to back, but this is recommended as it yields better results. The tensioning device provides sufficient force to keep the corrugated cardboard flat and unfolded. Proceeding one by one ensures good stretching each time. Conversely, simultaneous creasing results in unevenness and bulging due to the obstruction of the tensioning mechanism by the first second creasing component, and the further back in the creasing process, the less even the corrugated cardboard becomes between adjacent components, leading to uneven creasing and insufficient creasing uniformity.

[0024] Preferably, the first indentation assembly includes a left first roller mounting bracket 21 and a right first roller mounting bracket 22 that are movable vertically and spaced apart, and a first left roller 210 with an axial direction in the left-right direction mounted on the left first roller mounting bracket 21 and a first right roller 220 with an axial direction in the left-right direction mounted on the right first roller mounting bracket 22. The left first roller mounting bracket 21 and the right first roller mounting bracket 22 can be existing roller brackets, such as an inverted U-shaped roller bracket. Both the left first rolling roller mounting bracket 21 and the right first rolling roller mounting bracket 22 need to be able to move up and down, i.e., to lift up and down, and preferably also to move forward, backward, left, and right. Existing mobile devices can be used for this, such as mobile hydraulic cylinders or mobile pneumatic cylinders. The left first rolling roller mounting bracket 21 and the right first rolling roller mounting bracket 22 can be connected to the piston rod of a lifting mobile device y, thus achieving vertical movement. This mobile device y can be further connected to other mobile devices to achieve horizontal movement. This combination of existing mobile devices can achieve spatial movement. Alternatively, existing robotic arms can also be used. The first left rolling roller 210 and the first right rolling roller 220 are respectively mounted on the left first rolling roller mounting bracket 21 and the right first rolling roller mounting bracket 22 via axles.

[0025] In fact, there can be more than one first creasing assembly. When the width of the corrugated cardboard is large enough, multiple first creasing assemblies can be set on both sides, that is, multiple sets of first left pressure rollers 210 and first right pressure rollers 220. This allows for multiple sets of longitudinal creasing operations. However, this also means that longitudinal cutting is required afterward, because a piece of finally cut corrugated cardboard generally only has one set of left and right longitudinal creasing. Moreover, it generally only has one set of front and back transverse creasing. Therefore, after multiple second creasing assemblies form multiple sets of front and back transverse creasing, cutting is required. In this case, both transverse and longitudinal cutting are required to form individual final corrugated cardboard pieces.

[0026] Preferably, the second indentation assembly includes multiple sets of second rolling groups spaced apart front to back. Each second rolling group includes a second rolling wheel mounting frame 31 that moves up, down, left, and right, and a second rolling wheel 310 axially connected to the second rolling wheel mounting frame 31 in the front-back direction. The second rolling wheel mounting frame 31 can be an existing inverted U-shaped wheel frame, and it is also connected to the mobile device y to achieve spatial movement, similar to the aforementioned first rolling wheel mounting frame. The second rolling wheel 310, the first left rolling wheel 210, and the first right rolling wheel 220 can be existing rolling wheels, and can be three wheels with one continuous wheel surface.

[0027] Furthermore, the initial position of the second roller mounting bracket 31 is on the left or right side of the support plate 1. Since the longitudinal rolling operation has just begun, the pulling mechanism will move back and forth to avoid interference. The left first roller mounting bracket 21 and the right first roller mounting bracket 22, however, remain in a rearward position on the support plate 1. The output guide roller assembly is located behind the support plate 1. Thus, the original corrugated cardboard comes from the rear, undergoes the first longitudinal creasing, and is then pulled to the front for the second transverse creasing.

[0028] Preferably, the upper surface of the support platform 1 is a smooth steel surface. The smooth surface facilitates the dragging of the corrugated cardboard.

[0029] Furthermore, the pulling mechanism includes a front pulling component for pulling the corrugated cardboard forward and a rear positioning component for pressing and positioning the corrugated cardboard, which are distributed front and rear above the support platform 1. In this embodiment, the pulling mechanism consists of two parts: one is to provide power for actual pulling, and the other is to position and ensure the stability of the corrugated cardboard. That is, after the first indentation is completed, the rear positioning component should position the corrugated cardboard, and then the front pulling component should provide a certain pressure to flatten the corrugated cardboard.

[0030] Specifically, the front traction assembly includes a traction bracket 41 that can move back and forth and up and down, and a traction vacuum suction cup 410 that is installed and connected to the traction bracket 41 and can suck the upper surface of the corrugated cardboard downward. The traction bracket 41 can be an existing movable beam, and the traction bracket 41 also needs to be connected to an existing mobile device y to achieve movement. The traction vacuum suction cup 410 can be an existing suction cup, but the suction cup opening is downward. The traction vacuum suction cup 410 can be installed and fixed to the traction bracket 41 in an existing manner.

[0031] Furthermore, the rear positioning component includes a positioning bracket 51 that can move up and down, and a positioning vacuum suction cup 510 that is installed and connected to the positioning bracket 51 and can be suctioned downward to the upper surface of the corrugated cardboard. The positioning bracket 51 can adopt the structure of the pull bracket 41, and the positioning vacuum suction cup 510 can adopt the same structure as the pull vacuum suction cup 410. In fact, the structures of the front pull component and the rear positioning component can be the same, but their actions and roles are different. In actual operation, the original corrugated cardboard is manually or mechanically guided forward through the output guide roller assembly and placed at the rear of the support platform 1. Then, the vacuum suction cup 410 is pulled down to press and hold the upper surface of the corrugated cardboard. At this time, the first left roller 210 and the first right roller 220 should also be lowered to a position where they can longitudinally indent the corrugated cardboard. Then, the pull bracket 41 is moved forward, which will drag the corrugated cardboard forward. The first left roller 210 and the first right roller 220 perform longitudinal indentation on the corrugated cardboard, that is, front and back indentation. Of course, if the space is limited, it can only be done in sections. If the space is large enough, it can be completed in one go. For example, if space is limited, say it can be dragged for 20 meters, and then the pulling vacuum suction cup 410 stops. At this time, the positioning vacuum suction cup 510 presses down on the rear upper surface of the corrugated cardboard and holds the cardboard in place. The positioning vacuum suction cup 510 remains stationary, while the pulling bracket 41, where the pulling vacuum suction cup 410 is located, applies a slight forward force to maintain the flattened state of the corrugated cardboard. Then, multiple second creasing components begin to work, preferably sequentially from front to back, i.e., the foremost second rolling roller 31 starts first. The first round of creasing begins from left to right or in the opposite direction, followed by subsequent second-roller 310s, one by one, until the last second-roller 310 finishes creasing. The positioning vacuum suction cup 510 then releases and moves backward to the un-creased area of ​​the corrugated cardboard, pressing down on it and holding it in place. At this point, the positioning vacuum suction cup 510 can release and move upward, allowing for the next round of creasing. As the positioning vacuum suction cup 510 moves forward, the creasing from the first round is delivered to the area ahead, where it can be left unprocessed. However, it is best to cut it promptly. A cutting mechanism should be installed in front of the support platform 1, primarily for transverse cutting. Existing cutting equipment can be used. Rollers that press the corrugated cardboard vertically can be installed in front of the support platform 1, allowing for better cutting. Transverse cutting needs to be coordinated with creasing and is best performed during the second creasing operation, at which point the corrugated cardboard remains stationary.

[0032] Preferably, both the tension vacuum suction cup 410 and the positioning vacuum suction cup 510 are rectangular trumpet-shaped, which is more practical and more effective than a circular shape. The output guide roller assembly includes an upper guide roller 61 and a lower guide roller 62 that can be moved and adjusted vertically and are positioned vertically. Existing structures can be used to ensure the stability of the corrugated cardboard output direction.

[0033] Furthermore, a vertically extending vent 10 can be provided on the support platform 1. This allows for the installation of a front pulling assembly and a rear positioning assembly below the support platform 1, with the same structure as the upper front pulling assembly and rear positioning assembly. The vent 10 enables the lower pulling vacuum suction cup 410 and positioning vacuum suction cup 510 to draw air and apply it to the underside of the corrugated cardboard. The front pulling assembly and rear positioning assembly on the upper and lower parts of the support platform 1 simply need to maintain synchronized movement during operation. This will result in better performance.

[0034] Through the above-mentioned equipment modifications, corrugated cardboard can be creasing more effectively, with better and more uniform creasing results, higher efficiency, and better production, resulting in higher final product quality.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
