The second return spring 18 is a compression spring.
The arc-shaped trigger strip 7 is of a quarter-circle structure.
According to the packaging equipment designed by the invention, the length of the mounting strip 1 is designed, so that two hands of a user cannot simultaneously press the trigger strips 7 on two sides.
The specific working process is as follows: when the hot pressing strip 4 designed by the invention is used, in a normal working state, when the hot pressing strip starts to work, the two safety buttons 23 are pressed, the two pull rods 2 drive the mounting strip 1 to slide towards one side for placing the packaging bag through the two anti-clamping springs 5, and the mounting strip 1 slides to drive the two touch springs 7 arranged on the mounting strip to slide; in the sliding process of the two touch springs 7, the packaging bag can be extruded after the two touch springs 7 are in contact with the packaging bag, and the rear side of the packaging bag is provided with a pressing plate for pressing the packaging bag by the hot pressing strip 4, so that the two touch springs 7 can be extruded by the pressing plate on the rear side of the packaging bag to slide towards the inner side of the mounting strip 1; the two trigger springs 7 press the corresponding mounting plate 19 so that the mounting plate 19 slides towards the pull rod 2 on the corresponding side; the mounting plate 19 can drive the clamping block 8 and the limiting rod 6 which are mounted on the mounting plate to slide; so that the limiting rod 6 is gradually separated from the corresponding connecting rod 10 on the anti-pinch strip 3; when the limiting rod 6 arranged on the mounting strip 1 is completely separated from the connecting rod 10 arranged on the anti-pinch strip 3, the limiting rod 6 arranged on the mounting strip 1 loses the limiting on the anti-pinch strip 3, and the anti-pinch strip 3 can slide towards one side far away from the packaging bag relative to the mounting strip 1; at the moment, the front end of the touch spring 7 is flush with the front end of the anti-pinch strip 3, the front ends of the fixture blocks 8 arranged on the mounting plates 19 are not inserted into the corresponding clamping grooves 20, then the touch strip 7 is continuously extruded, meanwhile, the anti-pinch strip 3 slides along with the touch strip, in the subsequent sliding process, the fixture blocks 8 arranged on the two mounting plates 19 are gradually inserted into the corresponding clamping grooves 20, after the front ends of the anti-pinch strip 3 and the two touch springs 7 are flush with the front end of the mounting strip 1, the two fixture blocks 8 are also just inserted into the clamping grooves 20 on the two pull rods 2, at the moment, the two pull rods 2 and the mounting strip 1 move together, meanwhile, the sealing parts of the packaging bags are spread by the spreading rods on the two sides of the continuous automatic packaging belt manufacturing equipment, the mounting strip 1 presses the sealing end of the packaging bag, after a few seconds, the packaging bags are separated under the; the pull rod 2 pulls the mounting strip 1 to reset, after the two touch springs 7 mounted on the mounting strip 1 are separated from the packaging bag, the mounting plate 19 resets under the action of the second reset spring 18, and the mounting plate 19 resets to drive the clamping block 8 and the limiting rod 6 mounted on the mounting plate to reset; meanwhile, the mounting plate 19 resets to drive the movable spring 7 to reset; after the anti-pinch strip 3 is separated from the packaging bag, the anti-pinch strip resets under the action of the first return spring 9, and the limiting rod 6 is inserted into one side of the corresponding connecting rod 10 again under the combined action of the first return spring 9 and the second return spring 18.
When the user presses the fingers on the front side of the anti-pinch strip 3, because the thickness of the fingers of the general adult is more than 10mm, therefore, when the two pull rods 2 drive the mounting strip 1 and the anti-pinch strip 3 to slide together, fingers are ensured to contact with the side pressing plate behind the packaging bag, the fingers are squeezed by the pressing plate, however, because in this state, the two trigger springs 7 are not triggered, the limit rod 6 and the connecting rod 10 on the anti-pinch strip 3 are not separated, therefore, under the condition, the anti-pinch strip 3 can be pressed by fingers to move backwards, the anti-pinch strip 3 drives the mounting strip 1 to move backwards relative to the two pull rods 2 through the limiting rod 6 and the mounting plate 19, the two anti-pinch springs 5 are compressed, meanwhile, the front end of the anti-pinch strip 3 is not contacted with the hot pressing plate on the mounting strip 1, the finger is located the hot platen contact promptly, has prevented to a certain extent that the user from pressing the finger in the working process in the front side of preventing pressing from both sides strip 3, causes the user finger to press from both sides and injures the scald.
When a child presses fingers on the front side of the anti-pinch strip 3, because the thickness of the fingers of a common child is less than 3mm, so that in the process that the two pull rods 2 drive the mounting strip 1 and the anti-pinch strip 3 to slide together, the two touch springs 7 are extruded and moved back, before the fingers of the child contact with the rear side pressing plate of the packaging bag, the limiting rod 6 arranged on the mounting strip 1 and the connecting rod 10 on the anti-pinch strip 3 are not separated, in this case, the anti-pinch strip 3 can be pressed by the fingers of the child to move backwards, the anti-pinch strip 3 drives the mounting strip 1 to move backwards relative to the two pull rods 2 through the limiting rod 6 and the mounting plate 19, the two anti-pinch springs 5 are compressed, meanwhile, the front end of the anti-pinch strip 3 is not contacted with the hot pressing plate on the mounting strip 1, the fingers are in contact with the hot pressing plate, so that the condition that children press the fingers on the front side of the anti-pinch strip 3 carelessly in the working process to a certain extent to cause the fingers of the user to pinch and scald is avoided.
In the working process, when the finger of a user presses on one of the two touch springs 7, the mounting plate 19 on the corresponding side is activated, while the mounting plate 19 on the other side is not activated, in this state, the limit rod 6 on the side which is not triggered can not be triggered to be separated from the pull rod 2 on the anti-pinch strip 3, the anti-pinch strip 3 can not slide relative to the mounting strip 1, when fingers contact with a pressing plate on the rear side of the packaging bag, the anti-pinch strip 3 can be pressed by the fingers to move backwards, the anti-pinch strip 3 drives the mounting strip 1 to move backwards relative to the two pull rods 2 through the limiting rod 6 and the mounting plate 19, the two anti-pinch springs 5 are compressed, meanwhile, the front end of the anti-pinch strip 3 is not contacted with a hot pressing plate on the mounting strip 1, the fingers are in contact with the hot pressing plate, so that the fingers are prevented from being pressed on the front side of the anti-pinch strip 3 in the working process to a certain extent, and the fingers of the user are prevented from being pinched and scalded.
