Description

Technical Field

[0001] The present invention relates to the technical field of intelligent equipment, and in particular to an automatic paper cutting device that is easy to inspect. Background Art

[0002] Automatic paper cutting equipment is a common equipment used in factories to produce and process paper products. Large-scale automatic paper cutting equipment can operate 24 hours a day. Figure 1 As shown, existing large-scale automated paper cutting equipment features a dual-station paper delivery mechanism. The paper strip at one station is conveyed from the upper layer to the rear by a complex upper roller assembly, while the paper strip at another station is conveyed from the lower layer to the rear by a complex lower roller assembly. Due to the different uses of the finished paper, the upper and lower layers of the paper strips are processed by different mechanisms before being conveyed together to the cutting mechanism at the rear, ultimately producing the desired finished paper. However, routine maintenance of the equipment requires frequent checks on the operating conditions of the upper and lower roller assemblies.

[0003] Because the height of large-scale automated paper cutting equipment exceeds 2 meters and can even reach 3 meters, it is necessary to place a ladder on the conveyor frame to check the operating status of the upper roller group. Even to check the operating status of the lower roller group, a stool needs to be placed on it. This process requires workers to climb up and down, which is not convenient. Summary of the Invention

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 2-4 shown.

[0026] The automatic paper cutting equipment that is easy to inspect provided in this embodiment includes a conveying frame 1, a ladder 2 is set on one side of the conveying frame 1, a guide rail 3 is set on one side of the conveying frame 1, two upper guide wheels 5 that match the guide rail 3 are provided on one side of the panel 4 of the ladder 2, and a winding wheel 6 that is synchronized with the upper guide wheel 5 is provided on the other side of the panel 4 of the ladder 2. A lifting plate 8 is provided between the two side plates 7 of the ladder 2, and the two winding wheels 6 are respectively close to the two side plates 7. The lifting plate 8 and the bottom plate 9 of the ladder 2 are connected in an L shape. The lifting plate 8 is provided with lower guide wheels 10 that are respectively close to the two side plates 7, and the panel 4 is provided with hanging wheels 11 that are respectively close to the two side plates 7. A hanging rope 12 that passes through the hanging wheel 11 and the lower guide wheel 10 and hangs the lifting plate 8 is wound on the winding wheel 6. A moving wheel 13 is provided at the foot of the ladder 2. When the ladder 2 moves along the guide rail 3, When moving, the two winding wheels 6 unwind the lifting rope 12 to form a downward trend of the lifting plate 8; a mounting opening 14 is provided on the two side plates 7, and a hanging wheel 15 is provided in the mounting opening 14. One end of the hanging rope on the hanging wheel 15 extends into the side plate 7 and is connected to the bottom plate 9, and the other end extends into the outside of the side plate 7 and is connected to a counterweight seat 16 suspended below the bottom plate 9. A through-hole 17 is provided on the counterweight seat 16, and a damping rod 18 is provided at the bottom of the bottom plate 9. An auxiliary wheel 19 is provided at the bottom end of the damping rod 18. Limiting rails 20 for limiting the lifting plate 8 are provided on the two side plates 7. When the lifting plate 8 forms a downward trend, the bottom plate 9 and the lifting plate 8 descend together to form an inspection port 21 between the panel 4 and the lifting plate 8. When the lifting plate 8 and the bottom plate 9 descend to before the lifting plate 8 leaves the limiting rail 20, the damping rod 18 penetrates the through-hole 17.

[0027] In this embodiment, because the operating status of the upper and lower roller groups needs to be inspected, it would be inconvenient for workers to climb up and down, as mentioned in the background technology. Therefore, the automated paper cutting equipment provided in this embodiment is an improvement on traditional automated paper cutting equipment, achieving the beneficial effect of more convenient maintenance and inspection. Specifically, whether inspecting the upper or lower roller group, workers no longer need to leave the ladder 2, even when changing inspection locations. To inspect the upper roller group, corresponding to the position above the conveyor frame 1, workers climb the ladder 2 as usual and stand on the base plate 9 to inspect the upper roller group. To inspect the lower roller group, the motor 23 is controlled to operate, driving the upper guide wheel 5 toward the side where the lower roller group is located, and the entire ladder 2 moves laterally along the guide rail 3. The shift wheel 13 serves as a tool to assist in the lateral movement of the ladder 2. It should be noted that the upper and lower roller groups of the automated paper cutting equipment for easy inspection are staggered in their position on the assembly line. As ladder 2 moves laterally, reel 6 rotates synchronously with upper guide wheel 5 to lower lift plate 8. It should be noted that when motor 23 is rotating, lift plate 8 is suspended below panel 4 by the positioning function of motor 23. As reel 6 unwinds, lift plate 8 and base plate 9 move downward, forming an increasingly larger inspection opening 21 between lift plate 8 and panel 4. Leveraging the operator's own weight, base plate 9 moves downward and counterweight seat 16 moves upward until the two contact, corresponding to the maximum opening of inspection opening 21.

[0028] In this embodiment, when the motor 23 is running, the weight of the person standing on the base plate 9 drives the base plate 9 and the lifting plate 8 downward. The counterweight 16 offsets a considerable portion of this force, allowing the base plate 9 and the lifting plate 8 to move downward smoothly. Furthermore, considering that the center of gravity of the person standing on the base plate 9 changes in real time with the movement of their limbs, the downward movement of the base plate 9 and the lifting plate 8 is restricted by the limit rails 20 before the lifting plate 8 completely leaves the limit rails 20, thus preventing any wobbling. Furthermore, when the lifting plate 8 and the base plate 9 descend to the point where they leave the limit rails 20, the damping rod 18 penetrates the perforation 17. That is, when they reach the lower position, the damping rod 18 intervenes to guide the lifting plate 8 and the base plate 9 to prevent wobbling.

[0029] In this embodiment, the damping rod 18 is supported on the ground by the auxiliary wheels 19 shortly after it enters the through-hole 17, providing soft support for the base plate 9 until the base plate 9 contacts the counterweight seat 16. After the auxiliary wheels 19 touch the ground, they can also serve as moving components of the base plate 9. Therefore, in this embodiment, by moving the ladder 2 laterally into position, a usable inspection opening 21 is formed below the lower roller assembly, allowing workers to lean out and inspect the area without having to climb up or down. This provides a certain degree of convenience and improves the safety of maintenance.

[0030] In one embodiment, Figure 4 shown.

[0031] The automatic paper cutting device provided in this embodiment is easy to inspect. A transmission box 22 is provided on one side of the panel 4 . A motor 23 is provided on the side panel 7 . The motor 23 is connected to the two upper guide wheels 5 through the transmission box 22 .

[0032] In this embodiment, the motor 23 is connected to the two upper guide wheels 5 through the transmission box 22, so that the two upper guide wheels 5 can rotate synchronously in the same direction, thereby achieving the horizontal movement of the ladder 2 along the guide rail 3.

[0033] In one embodiment, Figure 4 shown.

[0034] The automatic paper cutting equipment provided in this embodiment is easy to inspect, and one side of the panel 4 of the ladder 2 is further provided with a bottom wheel 24 that cooperates with the guide rail 3, the two upper guide wheels 5 are located above the guide rail 3, and the bottom wheel 24 is located below the guide rail 3.

[0035] In this embodiment, the two upper guide wheels 5 and the bottom wheel 24 form a structure attached to the top and bottom of the guide rail 3, which can prevent the upper guide wheel 5 from derailing. In this embodiment, the two upper guide wheels 5 are driving wheels and the bottom wheel 24 is a driven wheel.

[0036] In one embodiment, Figure 5 shown.

[0037] The automatic paper cutting device provided in this embodiment is easy to inspect, and a fixing part 25 is also provided on the panel 4. The hanging rope 12 is fixedly connected to the fixing part 25 after passing through the hanging wheel 11 and the lower guide wheel 10. A protective plate 26 is provided on the hanging wheel 11 and the fixing part 25.

[0038] In this embodiment, the protective plate 26 is provided to prevent the lifting rope 12 from escaping from the lifting wheel 11. By providing the lifting wheel 11 and the fixing member 25, especially by positioning them close to the side panel 7, it can be ensured that there is no obstruction in the middle of the opened inspection port 21.

[0039] In one embodiment, Figure 2 shown.

[0040] The automatic paper cutting device provided in this embodiment is easy to inspect, and a limit switch 27 is provided on the guide rail 3. When the ladder 2 moves to the limit switch 27, the motor 23 stops working.

[0041] In this embodiment, when the ladder 2 moves laterally to a position, it can be detected by the limit switch 27 and the motor 23 can be stopped from rotating.

[0042] In one embodiment, Figure 2 、 Figure 6,as well as Figure 7 shown.

[0043] The automatic paper cutting equipment provided in this embodiment is easy to inspect. The outer sides of the two side panels 7 are provided with a damping seat 28 located at the installation port 14. One end of the axle 47 of the hanging wheel 15 is connected to a hinge 29 and the other end is connected to a contact member 30. The two sides of the installation port 14 are respectively connected to a hinge port 31 and a limit port 32 opened on the side panel 7. The hinge 29 is connected to the hinge port 31 through a rotating shaft 33. The contact member 30 is embedded in the limit port 32. An upper arc rail 34 and a lower arc rail 35 are provided between the damping seat 28 and the side panel 7. The upper arc rail 34 and the lower arc rail 35 are respectively connected to the limit port The upper and lower side walls of the position opening 32, a bending spring 36 arranged along the upper arc rail 34 and the lower arc rail 35 are connected between the damping seat 28 and the contact member 30. The contact member 30 is limited in the position opening 32 under the action of the bending spring 36. A pull rope 37 is connected to the contact member 30. The pull rope 37 passes through the middle of the bending spring 36 and penetrates the damping seat 28. The two pull ropes 37 are connected at one place. A handle 38 is provided on the inner side of one side plate 7. The two ends of the handle 38 are connected to the connection point of the two pull ropes 37 through a two-dividing line 39 passing through the side plate 7. A damping groove 40 that matches the outer contour of the wheel axle 47 and the hanging wheel 15 is provided on the damping seat 28.

[0044] In this embodiment, a pullable handle 38 is provided for workers to grasp when leaning under the lower roller assembly. Grasping handle 38 indicates that the worker is performing an inspection. Pulling handle 38 then pulls contact member 30 out of stopper 32 and compresses spring 36 along the path of upper and lower curved rails 34 and 35. This process forces axle 47 and pulley 15 into damping groove 40. Damping seat 28 is filled with a rubber damping material. This damping groove 40 is formed within the damping material. The shape of damping groove 40 matches the contours of axle 47 and pulley 15. When axle 47 and pulley 15 are drawn into damping groove 40, rotation of pulley 15 is restricted. This means that during inspection, pulley 15 cannot rotate. Even if motor 23 drives lift plate 8 and base plate 9 upward, base plate 9 is locked in place by damping seat 28, preventing it from moving upward. At the same time, due to the tension of the suspension rope 12, the motor 23 can no longer drive the upper guide wheel 5 to rotate and move the ladder 2 horizontally. Correspondingly, when the handle 38 is pulled, the operator can always stay below the lower roller assembly, and the inspection port 21 remains in the fully open position, thus providing greater safety.

[0045] In one embodiment, Figure 2 shown.

[0046] The automatic paper cutting device for easy inspection provided in this embodiment has a plurality of pedals 41 arranged in a stepped manner between the two side panels 7. Guardrails 42 are provided on the side panels 7.

[0047] In this embodiment, the structure of the ladder 2 follows the structure of the existing ladder.

[0048] In one embodiment, Figure 3 shown.

[0049] The automatic paper cutting equipment provided in this embodiment is easy to inspect, and a locking tube 43 is provided on the guardrail 42 on one side panel 7, and a long rod 44 and a support rod 45 are provided on the guardrail 42 on the other side panel 7. A support tube 46 is provided on the support rod 45, and the long rod 44 is movably connected in the support tube 46 and can be extended into the locking tube 43 to enclose the space surrounded by the two side panels 7 and the panel 4.

[0050] In this embodiment, after the staff stands on the bottom plate 9, a closed space can be formed by the long rods 44. At this time, the staff stands at a high position, which has a certain degree of safety.

[0051] In one embodiment, Figure 2 shown.

[0052] The automatic paper cutting device provided in this embodiment is easy to inspect, and its handle 38 is located near the bottom of the side panel 7.

[0053] In this embodiment, when the inspection port 21 is not opened, the handle 38 is located near the bottom of the side panel 7. After the inspection port 21 is opened, the handle 38 is located at the height of the worker's shoulder or head due to the worker's lowering position.
