Abstract
The utility model discloses a phoenix eyes machine directly drives structure, including spindle motor, drive synchronizing wheel, main shaft, hold -in range, a plurality of leading wheel, tensioning assembly, a lower synchronizing wheel and lower, the drive synchronizing wheel install in on the main shaft, a lower synchronizing wheel install in it is epaxial down, the hold -in range is connected drive synchronizing wheel, a plurality of leading wheel and a lower synchronizing wheel, tensioning assembly acts on the hold -in range is located adjacent, the part of level between with two leading wheels of graphic settings roughly, tensioning assembly is including placing compression roller on the hold -in range, the compression roller install can with the compression roller axle of compression roller relative rotation, the compression roller axle is connected with removable weight through the connecting portion of vertical setting. The present invention uses the technical scheme, the weight can guarantee at any time that the hold -in range is in the tensioning state.
Description
Technical field
The utility model relates to a kind of phoenix eyes machine and directly drives structure, belongs to technical field of sewing equipment.
Background technology
Phoenix eyes machine, also known as eyelet buttonhole sewing machine, is a kind of industrial sewing machine being exclusively used in thick material clothes buttonhole in seam lock.So-called " round end " is that the buttonhole front end of webs lock is rounded.Be characterized in buttonhole anatomic shape, stitching is evenly solid.Lockstitch button holder is very important a kind of equipment in garment machinery, and eyelet buttonhole sewing machine is one relatively more conventional in current China lockstitch button holder.Lockstitch button holder is mainly used in processing the buttonhole in all kinds of dress ornament, is divided into straight buttonholing machine and eyelet buttonhole sewing machine, divides again ending and does not finish up two kinds.Driving synchronizing wheel and the lower shaft synchronizing wheel of existing phoenix eyes machine usually adopt and synchronously bring connection, the phenomenon such as displacement, vibration is had when running up in order to prevent Timing Belt, Timing Belt is provided with directive wheel and tension assembly carries out regulating and bit transitions, its transmission system is stablized.Such as disclosed in Chinese patent literature CN203144694U, a kind of eyelet buttonhole sewing machine directly drives structure.But, the tension assembly of existing phoenix eyes machine, can not along with Timing Belt degree of tightness change and at any time and automatic adjusting position pressure is applied to Timing Belt.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome defect of the prior art, provides one to execute Timing Belt at any time and automatically stressed
To achieve these goals, a kind of phoenix eyes machine of the present utility model directly drives structure, comprise spindle motor, drive synchronizing wheel, main shaft, Timing Belt, some directive wheels, tension assembly, lower shaft synchronizing wheel and lower shaft, described driving synchronizing wheel is installed on described main shaft, described lower shaft synchronizing wheel is installed on described lower shaft, described Timing Belt connects described driving synchronizing wheel, some directive wheels and lower shaft synchronizing wheel, and described tension assembly acts on the part between two directive wheels that described Timing Belt arranges in adjacent, general horizontal isoplanar; Described tension assembly comprises the pressure roller be placed on described Timing Belt, and described pressure roller is provided with can the pressure roller shaft that rotate relative to pressure roller, and described pressure roller shaft is connected with removable weight by the connecting portion vertically arranged.
Described tension assembly also comprises damped oscillation mechanism.
Described weight is copper billet, and the below of described weight is provided with magnet.
Adopt technique scheme, phoenix eyes machine of the present utility model directly drives structure, and described weight is pressed on Timing Belt, thus moment Action of Gravity Field is on described Timing Belt, when the possibility occurring in the long-time use procedure of Timing Belt loosening, then still ensure that Timing Belt is in tensioning state at once.Damped oscillation mechanism being set, weight can being made to leave standstill fast when swinging, also can prevent the unexpected stressed swing of weight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the present embodiment provides a kind of phoenix eyes machine directly to drive structure, comprise spindle motor (not shown), drive synchronizing wheel 1, main shaft 2, Timing Belt 3, three directive wheel 4a, 4b, 4c, tension assembly, lower shaft synchronizing wheel 6 and lower shaft 7, described driving synchronizing wheel is installed on described main shaft, described lower shaft synchronizing wheel is installed on described lower shaft, described Timing Belt connects described driving synchronizing wheel, three directive wheels and lower shaft synchronizing wheel, described tension assembly acts on described Timing Belt and is positioned at adjacent, two directive wheel 4a that general horizontal isoplanar is arranged, part between 4b, described tension assembly comprises the pressure roller 5 be placed on described Timing Belt, and described pressure roller 5 is provided with the pressure roller shaft 51 that can relatively with pressure roller 5 rotate, and described pressure roller shaft 51 is connected with removable weight 53 by the connecting portion 52 vertically arranged.
Described tension assembly also comprises damped oscillation mechanism.
Described damped oscillation mechanism is electromagnetic damping mechanism, and described weight 53 is copper billet, and the below of described weight 53 is provided with magnet 54.
Adopt technique scheme, phoenix eyes machine of the present utility model directly drives structure, and described weight is pressed on Timing Belt, thus moment Action of Gravity Field is on described Timing Belt, when the possibility occurring in the long-time use procedure of Timing Belt loosening, then still ensure that Timing Belt is in tensioning state at once.Damped oscillation mechanism being set, weight can being made to leave standstill fast when swinging, also can prevent the unexpected stressed swing of weight.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
