Abstract
The utility model relates to a kind of tensioner, the fork comprising base plate, be fixedly installed in fixed link on base plate and swing arm and be articulated with below swing arm, described fixed link and fork are provided with pinch rolls, described base plate is also provided with cylinder, and described cylinder piston rod promotes fork away from fixed link.The all parts needed are fixedly installed on a base plate by the utility model, make this structure installment convenient.Be designed to a fixed link and a fork in addition, as long as provide the propulsion source of operation fork, make structure simpler.This structure only needs cylinder to promote fork swing, and energy-conserving and environment-protective more, also can realize one man operation and reload.
Description
Technical field
The utility model relates to the production facilities of paper for daily use and amenities product, and what especially relate to is a kind of tensioner.
Background technology
In the production processs such as sanitary napkin, paper diaper, nursing pad, need to carry out stretch-draw to portion of material, make it obtain good spreading.Tensioner mainly two hold-down arms and be movably hinged two forks under hold-down arm, because two hold-down arms of existing this area tensioner are separately fixed on wall, requirement must first be carried out measuring distance and install, install and bother very much, installation site is easily caused to offset, particularly lay man, even causes equipment normally to work.Existing tensioner is in addition all that setting two swing arms are rotating, requires that it is by two propulsions source, causes complex structure and increases energy consumption.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of structure is simple, easy for installation, the tensioner of energy-conserving and environment-protective.
For achieving the above object, technical solution of the present utility model is: tensioner, the fork comprising base plate, be fixedly installed in fixed link on base plate and swing arm and be articulated with below swing arm, described fixed link and fork are provided with pinch rolls, described base plate is also provided with cylinder, and described cylinder piston rod promotes fork away from fixed link.
Preferably, described fixed link is obliquely installed, in vertical state under described fork normality.
Preferably, be provided with piston rod fulcrum above described fork, when described cylinder is upheld, piston rod puts forth effort on piston rod fulcrum.
Preferably, described base plate is provided with cylinder block, described cylinder is installed on cylinder block.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: all parts needed are fixedly installed on a base plate by the utility model, make this structure installment convenient.Be designed to a fixed link and a fork in addition, as long as provide the propulsion source of operation fork, make structure simpler.This structure only needs cylinder to promote fork swing, and energy-conserving and environment-protective more, also can realize one man operation and reload.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
(1, base plate; 2, swing arm; 3, fixed link; 4, fork; 41, piston rod fulcrum; 5, cylinder; 51, piston rod; 52, cylinder block; 6, pinch rolls).
Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, tensioner, comprise the fork 4 being installed on base plate 1 top link 2, fixed link 3, cylinder 5 and being movably hinged below swing arm 2, cylinder 5 is fixed on base plate by cylinder block 52.
When base plate 1 stands on ground, fork 4 is without being vertical during External Force Acting, and fixed link 3 is tilt compared to fork 4.Be provided with piston rod fulcrum 41 at fork 4, when cylinder 5 is upheld, piston rod 51 is put forth effort on piston fulcrum 41 and is promoted fork 4 away from fixed link 3.Above fixed link 3 and fork 4, transverse row shows many pinch rolls 6, needs the material stretched to be around in these pinch rolls 6.
The utility model is specifically implemented, and common staff directly base plate 1 can be fixed on wall or other are local, installs very simple.In a particular application, promote fork 4 away from fixed link 3 by cylinder 5, under its effect, make material more smooth.When material is finished, only need control cylinder 5 to shrink, fork 2 under gravity, can automatically return to vertical state, fix without the need to external force, and single the completing of this structure workman is reloaded, and structure is simple, easy to operate, saves manpower, energy-conserving and environment-protective more simultaneously.
Above-described, be only preferred embodiment of the present utility model, the scope that this practicality is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
