An emergency braking device

Abstract

This utility model discloses an emergency braking device, including a frame, a conveyor belt installed inside the frame, a drive motor installed on one side wall of the frame, a packaging machine body fixed to the upper end of the frame, and an observation window installed on one side wall of the packaging machine body. The beneficial effects are as follows: This utility model, by setting up an emergency braking mechanism composed of a limit switch, a rocker arm, a force-bearing block, and a rope, allows for the following operation: During the use of the packaging machine, one end of the rope is connected to the worker's wristband. When it is necessary to inspect the interior of the packaging machine, opening the observation window applies external force to the rocker arm through the force-bearing block, causing it to rotate. This opens the normally closed contact and closes the normally open contact, thereby controlling the main circuit to cut off power and achieving emergency braking of the conveyor belt and the packaging machine body. Simultaneously, if a worker falls due to discomfort, the rope applies external force to the rocker arm, similarly disconnecting the main circuit through the limit switch, thus achieving emergency braking and effectively improving the safety of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of emergency braking technology for packaging machines, and specifically to an emergency braking device. Background Technology

[0002] Packaging machines are machines that package products, serving to protect and enhance their appearance. Packaging machines mainly fall into two categories: 1. Automated production line packaging; 2. External packaging equipment for products.

[0003] Existing assembly line packaging bases require a worker to observe the equipment's operation during use so that they can report any malfunctions in an emergency. However, during the inspection, the equipment may continue to operate, which could easily lead to safety accidents. Furthermore, it is impossible to apply an emergency brake if the worker becomes unwell, resulting in low installation reliability. Therefore, there is an urgent need for an emergency braking device to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide an emergency braking device in light of the current state of the technology.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes an emergency braking device, including a frame, a conveyor belt installed inside the frame, a drive motor installed on one side wall of the frame, a packaging machine body fixed at the upper end of the frame, an observation window installed on one side wall of the packaging machine body, a limit switch also installed on one side of the upper end of the packaging machine body, a rocker arm reserved on the limit switch, a force-bearing block fixed on one side wall of the rocker arm, and a rope fixed at the bottom end of the rocker arm.

[0006] Furthermore, the conveyor belt is rotatably mounted inside the frame via a built-in rotating shaft, and the surface of the conveyor belt is coated with a wear-resistant coating.

[0007] Furthermore, the output shaft of the drive motor is fixedly connected to the built-in rotating shaft of the conveyor belt, and the drive motor is fixed to one side wall of the frame by bolts.

[0008] Furthermore, the packaging machine body is fixed to the upper end of the frame with screws, and the conveyor belt passes through the packaging machine body.

[0009] Furthermore, multiple sets of baffles are symmetrically installed on the upper ends of both side walls of the packaging machine body, and the baffles are made of rubber.

[0010] Furthermore, the observation window is hinged to one side wall of the packaging machine body, and a pull handle is provided on one side wall of the observation window.

[0011] Furthermore, the limit switch is fixed to one side wall of the packaging machine body by screws, the rocker arm is rotatably connected to the limit switch, the force-bearing block is fixed to one side wall of the rocker arm by screws, and the surface of the force-bearing block is an arc-shaped structure.

[0012] Furthermore, the limit switch is electrically connected to the drive motor and the drive circuit of the packaging machine body, and the rope is fixed to one end of the rocker arm.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention employs an emergency braking mechanism consisting of a limit switch, a rocker arm, a force-bearing block, and a rope. During the operation of the packaging machine, one end of the rope is connected to the worker's wristband. When it is necessary to inspect the interior of the packaging machine, opening the observation window causes the force-bearing block to apply external force to the rocker arm, causing it to rotate. This opens the normally closed contact and closes the normally open contact, thereby cutting off the power to the main circuit and achieving emergency braking of the conveyor belt and the packaging machine. Similarly, if a worker falls due to discomfort, the rope applies external force to the rocker arm, which also disconnects the main circuit via the limit switch, achieving emergency braking and effectively improving the safety of the equipment.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3As shown, an emergency braking device in this embodiment includes a frame 1, a conveyor belt 2 installed inside the frame 1 to transport packaging bags, a drive motor 3 installed on one side wall of the frame 1 to drive the conveyor belt 2 to rotate, a packaging machine body 4 fixed at the upper end of the frame 1 to automatically package the packaging bags, an observation window 6 installed on one side wall of the packaging machine body 4, a limit switch 7 also installed on one side of the upper end of the packaging machine body 4, a rocker arm 9 reserved on the limit switch 7, a force-bearing block 10 fixed on one side wall of the rocker arm 9, and a rope 8 fixed at the bottom end of the rocker arm 9, which can realize emergency braking by controlling the equipment circuit in an emergency.

[0018] like Figures 1-3 In this embodiment, the conveyor belt 2 is rotatably installed inside the frame 1 via a built-in rotating shaft. The surface of the conveyor belt 2 is coated with a wear-resistant coating. The output shaft of the drive motor 3 is fixedly connected to the built-in rotating shaft of the conveyor belt 2. The drive motor 3 is fixed to one side wall of the frame 1 by bolts. The packaging machine body 4 is fixed to the upper end of the frame 1 by screws. The conveyor belt 2 passes through the packaging machine body 4. Multiple sets of baffles 5 are symmetrically installed on the upper ends of both side walls of the packaging machine body 4. The baffles 5 are made of rubber. During use, the drive motor 3 drives the conveyor belt 2 to rotate, and the conveyor belt 2 transports the packaging bags into the packaging machine body 4 for automatic packaging.

When it is necessary to check the inside of the packaging machine body 4, during the opening of the observation window 6, the observation window 6 applies external force to the rocker arm 9 through the force block 10 to make it rotate, causing the normally closed contact to open and the normally open contact to close, thereby controlling the power outage of the main circuit and realizing the emergency braking of the conveyor belt 2 and the packaging machine body 4. At the same time, when the worker falls due to discomfort, the rope 8 applies external force to the rocker arm 9, and the limit switch 7 also disconnects the main circuit to realize emergency braking, thereby effectively improving the safety of the equipment.
