Abstract
The utility model relates to a rocker arm control pull frame. The rocker arm control pull frame comprises two rocker arms which are arranged up and down, wherein the middle of each rocker arm is fixed on a hinged shaft; a pressure roller is arranged on the left side of each rocker arm; a pressure balancing block is arranged on the right side of each rocker arm; the pressure balancing block is arranged on a slideway in each rocker arm in a sliding manner; the axle centers of the two pressure balancing blocks are connected through a connecting rod; the connecting rod is in parallel with the connecting ling of the two hinged shafts; the pressure balancing block on the lower part is connected with a rocker of an oscillating wheel; and a linear displacement sensor is arranged on the oscillating wheel. The rocker arm control pull frame has the beneficial effects that the oscillating amplitude of the oscillating wheel is detected and adjusted by the linear displacement sensor; and the two pressure balancing blocks are driven by the rocker to perform displacement, so that the height of the pressure roller is adjusted. In the rocker arm control pull frame, balance of the rocker arm is adjusted by adjusting the position of the pressure balancing blocks, so that the multiple control effect is achieved.
Description
Technical field
The utility model relates to a kind of rocking arm control pulling force frame, belongs to the production facilities technical field of medicine equipment spatula commonly used.
Background technology
The spatula machine all also just adopts comparatively conventional production equipment at present.In this technical field, through finding after the retrieval that domestic technology web sites also can not find the technical information of new research and development, comprises the official website of State Intellectual Property Office, Chinese mechanically-laid web etc.So that can summarize thinks; At present, domestic at least device fabrication enterprise is in that less input aspect the research and development of spatula machine or just simply be engaged in the production of legacy equipment; And, good solution is not proposed to the technical matters that exists in the legacy equipment.
The tension force of the feeding belt of spatula requires the tension force of two grog bands identical at present; If tension force difference then can bring the problem that a side tension force is big, opposite side tension force is little; Cause the packing typing back of product to produce poorly sealed lattice at last; Perhaps cause the packaging bag of product crooked, profile is not attractive in appearance or can not meet the requirement of packing.The mode that existing tension control mechanism adopts manually operated to regulate needs the piecemeal adjustment of operating personal, but can not reach the state of balancing tension fully, and itself need expend more energy the process of adjustment, but can not reach the tension force complete equilibrium.
The utility model content
The technical matters that the utility model will solve is the mode that the tension adjustment mechanism that overcomes the spatula of existing prior art adopts the operating personal manual regulation, and the problem of the low and state that is difficult to reach balanced of efficient provides a kind of rocking arm control pulling force frame.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Rocking arm control pulling force frame; Comprise being respectively in two rocking arms up and down, the middle part of each rocking arm is separately fixed on the hinge, and the left side of each rocking arm is equipped with pressure roll; The right side is equipped with the equilibrium of pressure piece; And what said equilibrium of pressure piece slided is installed on the rocking arm in-to-in slideway, and the axle center of said two equilibrium of pressure pieces connects through a connecting rod, and the line of said connecting rod and two hinges parallels; Equilibrium of pressure piece in the bottom is connected with the rocking bar of an escapement, and on the said escapement linear movement pick-up is installed.
The rocking arm control pulling force frame that the utility model provides; Its beneficial effect is; Detect and regulate through the amplitude of fluctuation of linear movement pick-up, drive two equilibrium of pressure pieces through rocking bar then and carry out displacement, and then reach the purpose of the height of regulating said pressure roll said escapement.In the utility model, can also adjust the purpose of the balance of rocking arm through the position of adjustment equilibrium of pressure piece, so can reach the effect of multiple control.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification sheets, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the constructional drawing of the described rocking arm control of the utility model pulling force frame.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1, the described rocking arm control of the utility model pulling force frame comprises being respectively in two rocking arms 1 up and down; The middle part of each rocking arm 1 is separately fixed on the hinge 9; The left side of each rocking arm 1 is equipped with pressure roll 2, and the right side is equipped with equilibrium of pressure piece 3, and being installed on the rocking arm 1 in-to-in slideway 4 of sliding of said equilibrium of pressure piece 3; The axle center of said two equilibrium of pressure pieces 3 connects through a connecting rod 5; The line of said connecting rod 5 and two hinges 9 parallels, and the equilibrium of pressure piece 3 in the bottom is connected with the rocking bar 6 of an escapement 8, and on the said escapement 8 linear movement pick-up 7 is installed.
The rocking arm control pulling force frame that the utility model provides; Its beneficial effect is; Detect and regulate through the amplitude of fluctuation of linear movement pick-up, drive two equilibrium of pressure pieces through rocking bar then and carry out displacement, and then reach the purpose of the height of regulating said pressure roll said escapement.In the utility model, can also adjust the purpose of the balance of rocking arm through the position of adjustment equilibrium of pressure piece, so can reach the effect of multiple control.
