Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper cutters, in particular to a paper cutter protection device. Background Art
[0002] At present, electric paper cutters are equipped with a paper cutter and a paper presser. These two key components are controlled by two independent mechanisms: the paper presser is operated by a foot switch mechanism, while the paper cutter needs to be activated by pressing the left and right button switches at the same time. In order to ensure the safety of operators and avoid hand injuries, infrared photoelectric protection devices are generally configured at the front end of paper cutters. The working principle of this device is that the infrared light-emitting tube on the left emits an infrared beam, which is received by the photosensitive tube on the right to form an infrared light band. When the device is enabled, once an object enters the light band area, such as the operator's hand, the infrared will be blocked, which will trigger the electronic application circuit to cut off the power supply, causing the paper presser and paper cutter to stop working immediately.
[0003] However, the selection of the installation position of the infrared photoelectric protection device has become a challenge. If the device is installed too close to the ground, not only the hands but even the paper being cut may block the infrared light band, causing the device to frequently cut off the power supply, greatly reducing work efficiency and even making operation difficult. On the contrary, if the device is installed too high, although the operator's hands or the objects being cut may have entered the danger zone, as long as they operate below the infrared light band, they will not block the light band. At this time, the protection device loses its proper function, increasing the risk of injury caused by the paper cutter and paper press.
[0004] In addition, the operation method of the foot switch of the paper press also brings potential safety hazards. As long as the foot switch is pressed, the paper press will be pressed down immediately. When cutting soft or thin paper, the operator's hands need to be close to the paper press, which increases the risk of the hand being crushed by the paper press, causing unnecessary troubles and harm to the operator and the company. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content
