Detailed Description
The invention will be further explained below with reference to a specific embodiment and the drawing.
As shown in fig. 1, in the protection device 100 for the cutter of the manual plate cutting machine used in the copper-clad plate industry, when the protection device 100 closes the feed port 201 of the plate cutting machine 200, the upper limb of an operator can be prevented from extending into the feed port 201 of the plate cutting machine 200.
The limit switch 140 is used for sensing the position of the protective baffle, and when the protective device 100 does not close the feed port 201 of the plate cutting machine 200, the limit switch 140 is in a disconnected state, so that the working power supply of the plate cutting machine 200 is cut off;
when the guard device 100 closes the feed port 201 of the plate cutting machine 200, the guard device is in a connected state, and the working power supply of the plate cutting machine 200 is connected.
That is, the limit switch 140 mainly functions that when the guard fence 110 is not completely put down or put down to a designated position, the cutter (not shown in the figure) does not perform a cutting action, so as to avoid cutting the hand of an operator, and perform foolproof and double-safety functions.
The protection device 100 specifically comprises a protection baffle 110 movably installed at a feed inlet 201 of the plate cutting machine 200, the protection baffle 110 is a hollow baffle structure supported by steel pipe supports 121, 122, 123 and 124 matched at intervals and steel pipes 121a, 122a, 123a and 124a, the steel pipe supports 121, 122, 123 and 124 are connected with installation interfaces 211, 212, 213 and 214 at the feed inlet 201 of the plate cutting machine 200 through threaded fasteners 131, 132, 133 and 134, so that the protection baffle 110 axially rotates around the threaded fasteners 131, 132, 133 and 134, and a limit switch 140 used for sensing the movement position of the protection baffle 110 is further installed on one side of the protection baffle 110.
The protective baffle 110 is not a solid baffle, and is a steel frame structure formed by welding 4 steel pipes 121a, 122a, 123a, 124a with the length of about 2m and the diameter of about 3mm in parallel, and the distance between each steel pipe 121a, 122a, 123a, 124a is 10 mm. Thus, when the cutting is convenient, the cutting position and the size can be observed.
When the protective baffle 110 is perpendicular to the board placing table 220 at the feeding port 201 of the board cutting machine 200, the distance between the lowest part of the protective baffle 110 and the board surface of the board placing table 220 is not more than 5mm, so as to prevent the hands of an operator from passing through.
Because of possessing the above structure, the utility model discloses a work flow and principle lie in:
when a person cuts, whether the protective baffle 110 is placed in place or not is firstly confirmed, the protective baffle 110 is not in place, and whether the standard protective baffle 110 is perpendicular to the board surface of the board placing table 220 or not is judged, and the standard protective baffle is in contact with the limit switch 140. The cutting action is not performed.
When the guard 110 needs to be lowered to the sensing position of the limit switch 140, a cutting switch (not shown) of the plate cutting machine 200 is stepped to perform a cutting operation, and the cutting is completed.
The utility model provides a guard flap 110 mainly plays the separation effect on the physics, prevents that operating personnel from placing the hand under cutting sword (not shown in the figure) to avoid the emergence of industrial accident.
The limit switch 140 is mainly used to prevent individual personnel from operating carelessly or contrary to the operating specification, and a protective baffle is not used or not placed in place, so that the risk that a hand is placed under a cutter (not shown) is avoided when the hand feeds materials.
