Abstract
The utility model provides a flexible U-shaped cutting device for transparent paper outside a box. The flexible U-shaped cutting device comprises a compression roller, a cutter holder and a U-shaped cutter rotatably disposed on the cutter holder. A transparent paper conveying passage is formed between the compression roller and the cutter holder. The cutting device further comprises a swing arm disposed on one side of the cutter holder. The free end of the swing arm is connected with the compression roller. A limit spring is disposed on one side, opposite to the cutter holder, of the swing arm. When the U-shaped cutter rotates to the position of the compression roller, the compression roller is in non-rigid contact with the edge of the U-shaped cutter under spring force, impact to the edge is lowered greatly, cutting force adjustability of the U-shaped cutter is achieved, and the service life of the U-shaped cutter is prolonged.
Description
Technical field
The utility model relates to the packing device of tobacco business, relates in particular to a kind ofly can reduce the impulsive force that U-shaped cutter bears, and improves the U-shaped cutter outer U-shaped notching device of cellophane paper of flexible box in service life.
Background technology
As shown in Figure 1, in the prior art, the cutting mode that the U-shaped notching device of the outer cellophane paper of box adopts is that the blade of U-shaped cutter 3 contacts with the direct rigidity of pressure roller 1.Its operation principle is: U-shaped cutter 3 is arranged in rotating shaft 10 by U-shaped knife rest 2; Pressure roller 1 is arranged on bracing frame 6; Cellophane paper 3 is between U-shaped cutter 3 and pressure roller 1; When rotating shaft 10 drives U-shaped cutter 3 to be rotated counterclockwise contact with pressure roller 1, U-shaped cutter 3 and pressure roller 1 have produced extruding cutting force, at cellophane paper 4, cut out a U-shaped edge of a knife.But owing to being that direct rigidity contacts between U-shaped cutter 3 and pressure roller 1, impulsive force is large, U-shaped cutter is low 3 service lifes.
Utility model content
Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, provides a kind of flexible box the outer U-shaped notching device of cellophane paper, for solving the problems of the prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of flexible box the outer U-shaped notching device of cellophane paper, comprise pressure roller, knife rest and be rotatably provided in the U-shaped cutter on described knife rest, between described pressure roller and knife rest, form cellophane paper transfer passage, also comprise the swing arm that is arranged on described knife rest one side, the free end of described swing arm connects described pressure roller, and swing arm is provided with a limit spring with the phase dorsal part of knife rest.
Further, described swing arm is hinged on a bracing frame bottom, and described limit spring two ends are connected with support frame as described above and swing arm respectively.
Further, support frame as described above is provided with to regulate the adjusting bolt of described limit spring pretightning force.
Further, described swing arm below is provided with a limited block.
By above technical scheme, the utility model has following technique effect compared to prior art: U-shaped cutter is when rotating to pressure roller position, pressure roller is realized non-rigid contact with U-shaped cutter blade under spring-force driven dual, significantly reduce the impulsive force to blade, and realize the adjustability of U-shaped cutter cutting force, increase the service life of U-shaped cutter.

The specific embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 2.Notice, appended graphic the illustrated structure of this description, ratio, size etc., equal contents in order to coordinate description to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
Consult shown in Fig. 2, be shown as the structural representation of the outer U-shaped notching device of cellophane paper of the utility model flexible box, comprise pressure roller 1, knife rest 2 and be rotatably provided in the U-shaped cutter 3 on knife rest 2, between pressure roller 1 and knife rest 2, form the transfer passage of cellophane paper 4, knife rest 2 tops are provided with bracing frame 6, bracing frame 6 bottoms are by the hinged swing arm 5 of bearing pin 9, the free end of swing arm 5 connects pressure roller 1, swing arm 5 tops connect limit spring 7, limit spring 7 other ends are connected with bracing frame 6, and bracing frame 6 is provided with to regulate the adjusting bolt 8 of limit spring 7 pretightning forces.
Rotating shaft 10 drives U-shaped cutter 3 to rotate counterclockwise, and when U-shaped cutter 3 moves to the contact position with pressure roller 1, pressure roller 1 is lifted, and under the pressure-acting of limit spring 7, pressure roller 1 has formed cutting force with U-shaped cutter 3, and cellophane paper 4 is cut out to a U-shaped edge of a knife.By rotation adjusting bolt 8, can regulate the pretightning force of limit spring 7, and then control the cutting force of U-shaped cutter, to realize the U-shaped otch of perfect cellophane paper.
As further improvement of the utility model, swing arm 5 belows are provided with a limited block 11.Before U-shaped cutter 3 moves to pressure roller 1 correspondence position, swing arm 5 is pressed on limited block 11 under limit spring 7 pressure-actings, and now U-shaped cutter 3 does not contact with pressure roller 1.
In sum, pressure roller of the present utility model is realized non-rigid contact with U-shaped cutter blade under spring-force driven dual, significantly reduces the impulsive force to blade, and realizes the adjustability of U-shaped cutter cutting force, increases the service life of U-shaped cutter.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
