Description

Technical Field

[0001] This utility model relates to the field of indentation and tangling machine technology, specifically to a safety protection device for an indentation and tangling machine. Background Technology

[0002] The creasing and cutting machine is the core equipment for creasing and cutting paperboard. It uses mechanical transmission to drive the creasing knife and the cutting knife to complete the squeezing and shearing action on the paperboard. During operation, the worktable and the area where the knife moves are high-risk operating areas, and protective structures are required to ensure the safety of the operators.

[0003] Traditional protective measures often use fixed barriers or manually sliding protective doors. While these can physically cover some hazardous areas, they lack an effective interlocking mechanism with the equipment start-up and shutdown system. Even when the protective barrier is open and the hazardous area is exposed, operators can still start the equipment via the control panel. This can easily lead to hand or arm contact with moving blades or transmission components due to misoperation, causing shearing or crushing injuries. Such safety hazards are even more prominent in scenarios involving frequent material changes and operator fatigue. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figures 1-4A safety protection device for an indentation and tangling machine includes two protective plates 1, each with a transparent observation plate 19. The transparent observation plate 19 allows the operator to easily observe the working status of the indentation and tangling machine in real time without compromising the sealing of the protective plates 1. The device also includes an adjustment mechanism, comprising a housing 2 with two first sliding grooves. A first connecting block 3 is slidably connected within each first sliding groove. A limit plate 4 is fixedly connected to the bottom end of each first connecting block 3. The bottom end of the limit plate 4 is fixedly connected to the protective plate 1. Two L-shaped... Plate 18, two L-plates 18 cooperate with two limiting plates 4. The cooperation between the L-plates 18 and the limiting plates 4 can further limit the movement range of the limiting plates 4. The top of the first connecting block 3 is fixedly connected to a limiting block 5. A slide bar 6 is fixedly connected to the limiting block 5. A gear 7 is provided between the two limiting blocks 5. The gear 7 is rotatably connected to the inner side wall of the housing 2. Each of the two slide bars 6 is provided with multiple protrusions 8 that mesh with the gear 7. The top of the two slide bars 6 is slidably fitted with a partition 9. The end faces of the partition 9 are fixedly connected to the inner side wall of the housing 2. A second slide bar is provided on the partition 9. The second sliding groove has a second connecting block 10 slidably connected to it. The second connecting block 10 is fixedly connected to the limit block 5. An adjusting block 11 is fixedly connected to the top of the second connecting block 10. A first electric push rod 12 is installed on the top of the partition 9. The output end of the first electric push rod 12 is connected to the adjusting block 11. Limit switches are installed on the two protective plates 1. The first electric push rod 12 drives one of the limit blocks 5 to move through the cooperation of the adjusting block 11 and the second connecting block 10. The gear 7, through the cooperation of multiple protrusions 8 and two slide bars 6, can realize the synchronous movement of the two protective plates 1. The sliding mechanism allows the two protective plates 1 to close and open. When the two protective plates 1 are closed, the pressure cutting machine is started via a limit switch. When the two protective plates 1 are open, the machine cannot be started, thus achieving the purpose of safety protection. A through guide hole is provided on the slide bar 6, and a guide rod 17 is slidably connected in the guide hole. Both ends of the guide rod 17 are fixedly connected to the inner wall of the housing 2. The sliding cooperation between the guide hole and the guide rod 17 can accurately limit the movement direction of the slide bar 6, preventing the slide bar 6 from deviating or shaking when it moves with the gear 7, and ensuring that the two protective plates 1 always slide smoothly along the preset trajectory.

[0023] It should also be noted that the lifting mechanism is used to adjust the height of the housing 2. The lifting mechanism includes two cylinders 13, which are fixedly connected to the housing 2. A second electric push rod 14 is installed inside the cylinder 13. The output end of the second electric push rod 14 is connected to a support column 15. The end faces of the support column 15 are all in sliding fit with the inner wall of the cylinder 13. The bottom end of the support column 15 is fixedly connected to a mounting plate 16. The second electric push rod 14 drives the support column 15 to move, so as to adjust the overall height of the housing 2 and the protective plate 1. It can be adapted to different models and heights of creasing and cutting machines, ensuring that the protective plate 1 can always accurately cover the dangerous working area of ​​the equipment. The mounting plate 16 makes it easy to fix the whole device to the equipment or the ground, avoiding the device from shifting and causing the protection to fail. A telescopic protective cover 20 is connected between the protective plate 1 and the cylinder 13. The telescopic protective cover 20 can completely cover the gap between the protective plate 1 and the cylinder 13, preventing paper scraps, waste materials or equipment parts generated when the creasing and cutting machine is working from popping out of the gap and injuring people.

[0024] In summary, the working principle and process of the safety protection device for the creasing and tangling machine are as follows: First, the mounting plate 16 is fixed to the ground or equipment base next to the creasing and tangling machine using bolts or other fasteners. Then, the circuit is connected to the creasing and tangling machine. Next, depending on the model and actual height of the creasing and tangling machine, the second electric push rod 14 is activated, causing it to move the support column 15, which in turn raises and lowers the housing 2 and the protective plate 1 until the protective plate 1 precisely covers the hazardous operating area of ​​the equipment. Then, the first electric push rod 12 is activated, causing it to move through the adjusting block 11 and the second connecting block 10... The limit block 5 and the slide bar 6 move, and the two slide bars 6 achieve synchronous reverse sliding by meshing with the gear 7 through multiple protrusions 8. Then, through the limit block 5, the first connecting block 3, and the limit plate 4, the protective plate 1 is driven to slide along the first slide groove until the two protective plates 1 are fully opened. At this time, the limit switch is disconnected and the creasing and cutting machine cannot be started. After that, the material to be processed is placed stably on the worktable of the creasing and cutting machine and positioned accurately. The first electric push rod 12 is started in reverse so that it drives the two protective plates 1 to close synchronously in reverse. When the protective plates 1 are fully closed and the limit switch is triggered, the creasing and cutting machine can be started to work.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
