Description

Technical Field

[0001] The invention relates to a corrugated paper conveying device, in particular to a corrugated paper disengageable transition conveying device. Background Art

[0002] Corrugated cardboard production equipment usually includes paper feeding unit, printing unit, creasing unit, slotting unit, die-cutting unit, folding and gluing unit, stacking and packaging unit, etc. Each component unit works in a unified and coordinated manner under the action of the power system and transmission system to jointly complete a series of processing operations such as paper feeding, multi-level printing, creasing, slotting, die-cutting, folding, gluing (or stapling), stacking and packaging of corrugated cardboard.

[0003] Before stacking and packaging, the folded corrugated paper boxes coming down from upstream need to be tilted upwards by a climbing mechanism, thereby increasing the height of the folded corrugated paper boxes so that there is sufficient depth to stack more corrugated paper boxes. In a fully automatic corrugated paper production line, the paper feeding unit, printing unit, crimping unit, slotting unit, die-cutting unit, folding and gluing (stitching) unit, climbing mechanism, and stacking and packaging unit are sequentially connected to form an inseparable whole. In actual production, the following problems exist:

[0004] 1. In daily production, it is often necessary to install, maintain, debug, overhaul and troubleshoot equipment in a stopped state. The entire production line is relatively long, especially for large corrugated paper production lines, which can be tens of meters long. When on-site personnel need to perform the above operations on the equipment on both sides of the production line, they have to frequently detour from both ends of the production line, walking a long distance, which seriously affects work efficiency.

[0005] 2. During the production debugging process, the production quality of the processed cardboard needs to be inspected and evaluated. Since all processing links are completed when the cardboard reaches the folding, gluing (stitching) and boxing unit, the existing corrugated paper production line is an inseparable whole line. The processed cardboard can only be taken out from the stacking and packaging unit at the end, causing the climbing mechanism and stacking and packaging unit to be in an idling state, resulting in a large amount of energy waste. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a corrugated paper detachable transition conveying device, which can be disconnected between the climbing mechanism and the upstream mechanism when necessary to form a channel for staff to pass through, making it convenient to carry out maintenance and other work on both sides of the production line, thereby improving work efficiency and avoiding idling of the climbing mechanism and stacking and packaging unit during production debugging, thereby reducing energy consumption.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A corrugated paper disengageable transition conveyor device is arranged upstream of a climbing mechanism and comprises a transition conveyor frame, a transition conveyor assembly, a transition conveyor drive mechanism and a swing drive mechanism;

[0009] One end of the transition conveyor frame is rotatably connected to the frame of the upstream mechanism or the downstream mechanism;

[0010] The transition conveying assembly is arranged on the transition conveying frame;

[0011] The fixed end of the swing drive mechanism is hinged on the frame of the upstream mechanism or the downstream mechanism, and the driving end of the swing drive mechanism is hinged to the transition conveying frame.

[0012] The working principle of the above-mentioned corrugated paper disconnectable transition conveyor device is as follows:

[0013] In the working state, the transition conveyor frame is horizontally located between the upstream mechanism and the downstream mechanism, and the transition conveyor drive mechanism drives the transition conveyor assembly to perform transition conveying on the corrugated paper; if the machine needs to be shut down for maintenance, the swing drive mechanism drives the transition conveyor frame to swing downward around its own rotation center, fold and close, and make a larger space for staff to pass through, making it convenient for installation, maintenance, debugging, inspection and troubleshooting on both sides of the production line, which can improve work efficiency and avoid idling of the climbing mechanism and stacking and packaging unit during production debugging, thereby reducing energy consumption.

[0014] In a preferred embodiment of the present invention, the corrugated paper breakable transition conveyor device comprises two sets, one of which is connected to the upstream mechanism and the other to the downstream climbing mechanism. This arrangement has the advantage of dividing the space between the upstream mechanism and the downstream climbing mechanism into two, with the two sets of transition conveyor racks filling the space. When downtime is required for maintenance, the two sets of transition conveyor racks can be folded up separately. Compared to a single transition conveyor rack, two transition conveyor racks are only half the length, allowing for a greater swing angle without interfering with the ground, resulting in a greater folding range and greater space for breakage.

[0015] A preferred embodiment of the present invention is that the transition conveying assembly includes a transition conveying belt and a transition conveying roller, the transition conveying roller includes an active transition conveying roller and a driven transition conveying roller, and the transition conveying belt is wound around the active transition conveying roller and the driven transition conveying roller.

[0016] Furthermore, the transition conveying drive mechanism is composed of the conveying drive mechanism of the upstream mechanism or the downstream mechanism;

[0017] The active transition conveying roller of the transition conveying assembly is composed of the driven conveying roller of the conveying assembly of the upstream mechanism or the downstream mechanism;

[0018] The active transition conveying roller is rotatably connected to the upstream mechanism or the downstream mechanism, and the transition conveying frame is rotatably connected to the active transition conveying roller. Through the above structure, not only can a set of driving mechanisms be shared, the structure is simplified, and the cost is reduced, but the same conveying speed can also be achieved.

[0019] Furthermore, the transition conveyor frame includes a fixed transition conveyor frame and a telescopic transition conveyor frame, the fixed transition conveyor frame is rotatably connected to the active transition conveyor roller, the telescopic transition conveyor frame is connected to the fixed transition conveyor frame through a slidable structure, and the driven transition conveyor roller is rotatably connected to the telescopic transition conveyor frame;

[0020] A telescopic transmission assembly is provided between the fixed transition conveyor frame and the upstream mechanism or the downstream mechanism. The telescopic transmission assembly includes a telescopic transmission sun gear, a telescopic transmission planetary gear, and a telescopic transmission rack. The telescopic transmission sun gear is fixedly mounted on the upstream mechanism or the downstream mechanism, and the center of the telescopic transmission sun gear is aligned with the center of the active transition conveyor roller. The telescopic transmission planetary gear is rotatably connected to the fixed transition conveyor frame and meshes with the telescopic transmission sun gear. The telescopic transmission rack is fixedly connected to the telescopic transition conveyor frame. With the above structure, when the swing drive mechanism drives the fixed transition conveyor frame to swing and fold downward about its own rotation center, the telescopic transmission planetary gear simultaneously rolls on the telescopic transmission sun gear, thereby pulling the telescopic transmission rack inward, causing the telescopic transition conveyor frame to gradually retract as it swings and folds, shortening the length of the entire transition conveyor frame and preventing the transition conveyor frame from interfering with the ground, thereby achieving the maximum swing and folding angle and further expanding the space after disconnection. This is very clever. Similarly, when the swing drive mechanism drives the fixed intermediate conveyor frame to swing upward and expand around its own rotation center, the telescopic transmission planetary gear pushes the telescopic transmission rack outward, causing the telescopic intermediate conveyor frame to gradually extend outward as it swings and expands, ensuring normal intermediate conveying operation. Furthermore, during the folding and unfolding process, the telescopic intermediate conveyor frame utilizes the power of the swing drive mechanism to simultaneously retract and extend, simplifying the drive mechanism.

[0021] Furthermore, the fixed transition conveyor frame is provided with a follower tensioning assembly, which includes a follower sliding tensioning seat, a follower tensioning rod, a first follower tensioning rack, a first follower tensioning wheel, a second follower tensioning wheel and a second follower tensioning rack;

[0022] The follower sliding tensioning seat is vertically slidably connected to the fixed transition conveyor frame;

[0023] The follower tensioning rod is rotatably connected to the follower sliding tensioning seat, and the follower tensioning rod is pressed on the transition conveyor belt;

[0024] The first follower tensioning rack is fixedly connected to the telescopic transition conveyor frame;

[0025] The first follower tensioning wheel is engaged between the first follower tensioning rack and the second follower tensioning wheel, the second follower tensioning wheel is engaged between the first follower tensioning wheel and the second follower tensioning rack, and the second follower tensioning rack is vertically fixedly connected to the follower sliding tensioning seat.

[0026] Through the above structure, when the fixed transition conveyor frame swings downward and folds, the telescopic transition conveyor frame retracts inward. At the same time, the first follower tensioning rack drives the first follower tensioning wheel to rotate, and then transmits power to the follower sliding tensioning seat through the second follower tensioning wheel and the second follower tensioning rack, and then drives the follower sliding tensioning seat to move downward, so that the follower tensioning rod presses down on the transition conveyor belt in real time, thereby ensuring that the transition conveyor belt is in a tensioned state in real time and will not be affected by the extension and retraction of the telescopic transition conveyor frame, ensuring normal conveying work.

[0027] Furthermore, the follower tensioning assembly further includes two fixed tensioning rods, which are located above the two sides of the follower tensioning rod and press against the transition conveyor belt.

[0028] In a preferred embodiment of the present invention, the transition conveying frame, the transition conveying assembly and the swing drive mechanism are provided in multiple groups and are arranged in a direction perpendicular to the direction of corrugated paper conveying.

[0029] In a preferred embodiment of the present invention, the swing drive mechanism comprises a swing drive cylinder, and the end of the telescopic rod of the swing drive cylinder is hinged to the transition conveyor frame.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The conveying device of the present invention is provided with a transition conveyor frame and a swing drive mechanism. When the machine needs to be shut down for maintenance, the swing drive mechanism drives the transition conveyor frame to swing downward around its own rotation center and fold and collapse, thereby making a larger space for workers to enter and exit, making it easier to carry out installation, maintenance, commissioning, inspection and troubleshooting on both sides of the production line, thereby improving work efficiency.

[0032] 2. When the production quality of the processed cardboard needs to be inspected and evaluated, it can be directly disconnected at the rear of the folding and gluing (stitching) box unit and the processed cardboard can be directly taken out without being transferred to the end of the production line, avoiding idling of the climbing mechanism and stacking and packaging unit and reducing energy consumption.

[0039] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0040] Example 1

[0041] Combine Figures 1-4 The corrugated paper can be disconnected from the transition conveying device of this embodiment, which is arranged upstream of the climbing mechanism 1, and includes a transition conveying frame 2, a transition conveying assembly, a transition conveying drive mechanism and a swinging drive mechanism; wherein, the transition conveying frame 2, the transition conveying assembly and the swinging drive mechanism are each provided with multiple groups and are arranged along a direction perpendicular to the corrugated paper conveying.

[0042] Combine Figures 1-4 One end of the transition conveyor frame 2 is rotatably connected to the frame of the upstream mechanism or the downstream mechanism; the transition conveying assembly is arranged on the transition conveyor frame 2; the fixed end of the swing drive mechanism is hinged to the frame of the upstream mechanism or the downstream mechanism, and the driving end of the swing drive mechanism is hinged to the transition conveyor frame 2.

[0043] Combine Figures 1-4 The said corrugated paper disconnectable transition conveyor device is provided with two groups, one of which is connected to the upstream mechanism, and the other is connected to the downstream climbing mechanism 1. The advantage of this arrangement is that the space between the upstream mechanism and the downstream climbing mechanism 1 can be divided into two, and filled by two groups of transition conveyor racks 2. When the machine needs to be shut down for maintenance, the two groups of transition conveyor racks 2 are respectively folded together. Compared with the arrangement of one transition conveyor rack 2, the arrangement of two transition conveyor racks 2 is only half the length. Under the premise of not interfering with the ground, it has a larger swing angle, that is, the folding range is larger, which is conducive to obtaining a larger disconnection space.

[0044] Combine Figures 1-4 The transition conveying assembly includes a transition conveying belt 3 and a transition conveying roller. The transition conveying roller includes an active transition conveying roller 4 and a driven transition conveying roller 5. The transition conveying belt 3 is wound around the active transition conveying roller 4 and the driven transition conveying roller 5.

[0045] Furthermore, the intermediate conveyor drive mechanism is composed of the conveyor drive mechanism of the upstream mechanism or the downstream mechanism; the active intermediate conveyor roller 4 of the intermediate conveyor assembly is composed of the driven conveyor roller of the conveyor assembly of the upstream mechanism or the downstream mechanism; the active intermediate conveyor roller 4 is rotatably connected to the upstream mechanism or the downstream mechanism, and the intermediate conveyor frame 2 is rotatably connected to the active intermediate conveyor roller 4. This structure not only allows a common drive mechanism, simplifying the structure and reducing costs, but also achieves the same conveying speed.

[0046] Combine Figures 1-4 The swing drive mechanism includes a swing drive cylinder 6, and the end of the telescopic rod of the swing drive cylinder 6 is hinged to the transition conveying frame 2.

[0047] Combine Figures 1-4 The working principle of the above-mentioned corrugated paper disconnectable transition conveying device is as follows:

[0048] In the working state, the transition conveyor frame 2 is horizontally located between the upstream mechanism and the downstream mechanism, and the transition conveyor drive mechanism drives the transition conveyor assembly to perform transition conveying on the corrugated paper; if the machine needs to be shut down for maintenance, the swing drive mechanism drives the transition conveyor frame 2 to swing downward around its own rotation center, fold and close, and make a larger space for staff to pass through, so as to facilitate installation, maintenance, debugging, inspection and troubleshooting on both sides of the production line, thereby improving work efficiency, avoiding idling of the climbing mechanism and stacking and packaging unit during production debugging, and reducing energy consumption.

[0049] Example 2

[0050] Combine Figure 5-Figure 7, different from Example 1, the transition conveyor frame of this embodiment includes a fixed transition conveyor frame 2-1 and a telescopic transition conveyor frame 2-2, the fixed transition conveyor frame 2-1 is rotatably connected to the active transition conveyor roller 4, the telescopic transition conveyor frame 2-2 is connected to the fixed transition conveyor frame 2-1 through a sliding structure, and the driven transition conveyor roller 5 is rotatably connected to the telescopic transition conveyor frame 2-2; a telescopic transmission assembly is provided between the fixed transition conveyor frame 2-1 and the upstream mechanism or the downstream mechanism, and the telescopic transmission assembly includes a telescopic transmission sun gear 7, a telescopic transmission planetary gear 8 and a telescopic transmission rack 9, the telescopic transmission sun gear 7 is fixedly set on the upstream mechanism or the downstream mechanism, the center of the telescopic transmission sun gear 7 is the same as the center of the active transition conveyor roller 4, the telescopic transmission planetary gear 8 is rotatably connected to the fixed transition conveyor frame 2-1 and engages with the telescopic transmission sun gear 7, and the telescopic transmission rack 9 is fixedly connected to the telescopic transition conveyor frame 2-2. Through the above-mentioned structure, when the swing drive mechanism drives the fixed transition conveyor frame 2-1 to swing downward around its own rotation center and fold, the telescopic transmission planetary gear 8 simultaneously rolls on the telescopic transmission sun gear 7, thereby pulling the telescopic transmission rack 9 inward, causing the telescopic transition conveyor frame 2-2 to gradually retract while swinging and folding, shortening the length of the entire transition conveyor frame 2 and preventing the transition conveyor frame 2 from interfering with the ground, so as to obtain the maximum swing folding angle and further expand the space after disconnection, which is very clever. Similarly, when the swing drive mechanism drives the fixed transition conveyor frame 2-1 to swing upward around its own rotation center and open, the telescopic transmission planetary gear 8 pushes the telescopic transmission rack 9 outward, causing the telescopic transition conveyor frame 2-2 to gradually extend outward while swinging and opening, thereby ensuring normal transition conveying operation. Furthermore, during the above-mentioned folding and opening process, the telescopic transition conveyor frame 2-2 uses the power of the swing drive mechanism to synchronously achieve contraction and extension operations, which can simplify the drive mechanism.

[0051] Furthermore, the fixed transition conveyor frame 2-1 is provided with a follower tensioning assembly, which includes a follower sliding tensioning seat 10, a follower tensioning rod 11, a first follower tensioning rack 12, a first follower tensioning wheel 13, a second follower tensioning wheel 14 and a second follower tensioning rack 15; the follower sliding tensioning seat 10 is vertically slidingly connected to the fixed transition conveyor frame 2-1; the follower tensioning rod 11 is rotationally connected to the follower sliding tensioning seat 10, and the follower tensioning rod 11 presses on the transition conveyor belt 3; the first follower tensioning rack 12 is fixedly connected to the telescopic transition conveyor frame 2-2; the first follower tensioning wheel 13 is meshed between the first follower tensioning rack 12 and the second follower tensioning wheel 14, the second follower tensioning wheel 14 is meshed between the first follower tensioning wheel 13 and the second follower tensioning rack 15, and the second follower tensioning rack 15 is vertically fixedly connected to the follower sliding tensioning seat 10.

[0052] Through the above structure, when the fixed transition conveyor frame 2-1 swings downward and folds, the telescopic transition conveyor frame 2-2 retracts inward. At the same time, the first follower tensioning rack 12 drives the first follower tensioning wheel 13 to rotate, and then transmits power to the follower sliding tensioning seat 10 through the second follower tensioning wheel 14 and the second follower tensioning rack 15, and then drives the follower sliding tensioning seat 10 to move downward, so that the follower tensioning rod 11 presses down on the transition conveyor belt 3 in real time, thereby ensuring that the transition conveyor belt 3 is in a tensioned state in real time, and will not be affected by the extension and retraction of the telescopic transition conveyor frame 2-2, ensuring the normal conveying work.

[0053] Furthermore, the follower tensioning assembly further includes two fixed tensioning rods 16 , which are located above the two sides of the follower tensioning rod 11 and press against the transition conveyor belt 3 .

[0054] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
