Abstract
The utility model discloses a yarn trapper assembly for an embroidery machine. The yarn trapper assembly comprises a yarn guiding wheel, a detection wheel and a yarn trapper which are sequentially arranged on a yarn trapper installing panel; the yarn trapper comprises a base and a yarn trapping threaded rod, the top end of the yarn trapper is a limiting end, and the tail end of the yarn trapper is provided with an upper locking wheel; a pressure spring, an upper yarn trapping disc, a lower yarn trapping disc, a yarn trapper base and an installing panel are sequentially sheathed at the periphery of the rod body of the yarn trapping threaded rod; the yarn trapping threaded rod is in threaded connection with the yarn trapper base; and the base is a hollow structure, and a locking spring, the top end of which is connected with a lower locking wheel is arranged in the base. According to the yarn trapper assembly, the traditional nut structure is avoided through the threaded connection of the yarn trapping threaded rod with the limiting end and the yarn trapper base, and as a threaded connection place between the yarn trapping threaded rod and the yarn trapper base is not subjected to the looseness force of yarn trapping between the upper yarn trapping disc and the lower yarn trapping disc, the impact on the yarn trapping force of the upper yarn trapping disc and the lower yarn trapping disc is effectively avoided, and the service life of the whole yarn trapper is prolonged.
Description
Technical field
The utility model relates to a kind of embroidery machine parts, relates in particular to a kind of embroidery machine tension disk assembly.
Background technology
The tension disk of embroidery machine is by being installed on the important device that wire-crossing wheel, detection are taken turns, tension disk carries out separated time, clamping, tension adjustment to embroidering line on the tension disk installation panel, owing to embroider the tension disk that line ceaselessly passes through tension disk, often cause tension disk loosening and lost the clamp ability, its tension disk main body of traditional tension disk of tracing it to its cause is to be made of nut and screw-rod structure, and the tension disk of this thread connecting mode is because thread connecting mode can not be avoided looseness fault all the time.
The Chinese invention patent patent No. 200810061379.1 discloses the control device of tension disk in a kind of Sewing machines, the control device of tension disk in this Sewing machines, tension disk is loaded on the sidepiece of sewing machine frame, control device comprises motor, electromagnet, thread tension releasing lever and clamp briquetting, motor be connected on the frame and motor and clamp briquetting between be provided with the clamp transmission mechanism, and the clamp transmission mechanism can make clamp briquetting Compress Spring, electromagnet be connected on the frame and electromagnet and thread tension releasing lever between be provided with the loose ends transmission mechanism, and the loose ends transmission mechanism can make the loose ends masthead pin outer end of bearing down on one.The control device of tension disk does not propose tension disk because the looseness fault that thread connecting mode causes in this kind Sewing machines.
Summary of the invention
The utility model provides a kind of simple in structure, failure rate is low, prevents the embroidery machine tension disk assembly of loose ends.
A kind of embroidery machine tension disk assembly, comprise the wire-crossing wheel, detection wheel, the tension disk that are installed on successively on the tension disk installation panel, described tension disk comprises that base and top are positive stop end, tail end is provided with locking clamp screw rod of taking turns, and the body of rod periphery of clamp screw rod is overlapped successively holddown spring, upper thread tension disc, lower thread tension disc, tension disk seat and installation panel; Described clamp screw rod is threaded with the tension disk seat; Described base is hollow structure, and inside is provided with the top and connects lower locking locking spring of taking turns.This kind employing is threaded with the tension disk seat with the clamp screw rod of positive stop end and then has evaded the nut structure of traditional use, because clamp screw rod and tension disk seat threaded connection place are not subject to the loosening power of clamp between thread tension disc and the lower thread tension disc, have effectively avoided the impact on upper thread tension disc and lower thread tension disc clamp power.Upper thread tension disc and lower thread tension disc clamp power are controlled by holddown spring only, and the spring force of holddown spring is controlled by the mutual alignment between clamp screw rod and the tension disk seat, as long as the mutual alignment between clamp screw rod and the tension disk seat is constant, so the constant clamp power that has guaranteed between upper thread tension disc and the lower thread tension disc of the spring force of holddown spring.Provide axial locking power as the locking spring of further technological merit in base to the threaded connection place of clamp screw rod and tension disk seat, prevented the clamp screw bolt loosening.
Described lower locking the wheel and the upper locking helical teeth that the face of being in contact with one another is equipped with projection of taking turns, the above-mentioned helical teeth that is in contact with one another on the face is intermeshing, has more prevented from connecting locking clamp screw rod radial rotary of taking turns; Described locking take turns and the clamp screw rod between be provided with jump ring, prevent that the clamp screw rod from getting loose.
The lamellar body of described upper thread tension disc and lower thread tension disc is provided with the short slot of perforation, is inserted with the wire winding pole that connects the tension disk seat in the short slot, and the convenient line of embroidering is crossed line.
Described tension disk is more than two, and the quantity of tension disk seat is identical with tension disk, and adjacent tension disk seat is the integrated injection molding structure, is fixedly connected on the installation panel, has improved monolithic stability, the steadiness of tension disk seat.
The utility model adopts the clamp screw rod with positive stop end to be threaded with the tension disk seat and then has evaded the nut structure of traditional use, because clamp screw rod and tension disk seat threaded connection place are not subject to the loosening power of clamp between thread tension disc and the lower thread tension disc, effectively avoided the impact on upper thread tension disc and lower thread tension disc clamp power, the service life of having improved tension disk integral body.
Description of drawings
Fig. 1 is the utility model embroidery machine tension disk assembly perspective view;
Fig. 2 is the structural representation that the utility model embroidery machine is used the tension disk of tension disk assembly.
The specific embodiment
A kind of embroidery machine tension disk assembly as shown in Figure 1, 2, comprise the wire-crossing wheel 4, detection wheel 3, the tension disk 2 that are installed on successively on the tension disk installation panel 1, tension disk 2 comprises that base 15 and top are positive stop end, tail end is provided with locking 9 the clamp screw rod 5 of taking turns, and the body of rod periphery of clamp screw rod 5 is overlapped successively holddown spring 11, upper thread tension disc 6, lower thread tension disc 7, the tension disk seat 8 that is threaded and installation panel 1; Base 15 is hollow structure, and inside is provided with the top and connects lower locking 14 the locking spring 10 of taking turns.Lower lockingly take turns 14 and upward lockingly take turns 9 and be in contact with one another the helical teeth that face is equipped with projection, cross radial rotary that line cause to prevent clamp screw rod 5 because embroider line by intermeshing helical teeth structure.
The lamellar body of preferably going up thread tension disc 6 and lower thread tension disc 7 as structure is provided with the short slot 13 of perforation, is inserted with the wire winding pole 12 that connects tension disk seat 8 in the short slot 13.Tension disk 2 is more than two, and the quantity of tension disk seat 8 is identical with tension disk 2, and adjacent tension disk seat 8 is the integrated injection molding structure, is fixedly connected on the installation panel 1.The quantity of tension disk 2 is generally 4,9,16 and arranges as required.
