Description

1234594 V. Description of the invention (1) [Field of the invention] The present invention relates to an improvement of a sewing machine drive mechanism assembly, and particularly to a sewing machine drive mechanism assembly which uses a bracket plate to connect the main shaft of the sewing machine and the main shaft of the motor. Transmission of mechanical fixation and mechanical power in between. [Previous technology check generally reported No. 454055 The drive belt side of the sewing machine passes through the moving belt often does not work well, for the control box under the table under the fixed vibration force is greater, the control element in the box, I do not control the box It is not possible to modify the machine head and horse sewing sewing of the present invention as shown in our patent. There is no one available on the main and worktables, and the drawbacks of long material transmission are fixed to the motor and the electric motor. The motor rotates the 'operation mechanism and electric control mechanism of the electric control sewing machine', but the sewing assembly is made of plates for a long time, so that the conventional sewing machines are fixed on the workbench. For example, the "sewing machine motor control device" Figure 3 It is located under the workbench. The belt head is used to achieve the transmission connection. The workbench must have a long slot, which is not only difficult to assemble and maintain. It is safe to take up the sewing thread, process the fabric and the fabric to be processed. : The general motor is suspended in an upside-down mode :: The motor is difficult to install and inconvenient to maintain ~ Together, the motor belt is secretly fixed from the ‘electric control box ’s long-term withstand rotation’. In addition, such as Yu Yu, will make the seam t, 彳 ㈣ the whole material _ under-looking at the beginning of the sewing machine drive mechanism assembly is directly combined into a single body] The drive mechanism of the hybrid makeup of the drive mechanism snail point swept away.

V. Description of the invention (2) [Summary of the invention] The above objective is to improve the good drive mechanism of the conventional sewing machine. , Point, and k for a novel sewing machine drive mechanism assembly modification_ Another purpose of the invention is to provide a sewing machine assembly modification P, which can share the most mechanical connection space between the motor of the machine and the sewing machine head ^, : = Its structure and assembly are #, and the mechanical action between the two can be minimized. The initial purpose of the present invention is to provide an improved sewing machine assembly. The drive mechanism motor and the sewing machine head are consolidated by a bracket plate to form a motor. The motor and the sewing machine are placed above the worktable surface, not only for assembly. Maintenance is easy, and the working environment is cleaner and more beautiful. Another object of the present invention is to provide an improved sewing machine drive mechanism assembly. 'Because the motor is set on the work surface, the drive belt no longer takes up the sewing thread and processes the fabric, making the operation of the sewing machine more flexible, faster and more efficient. . The above and other objects, effects, and features of the present invention will be made clear by the following detailed description of specific embodiments with reference to the accompanying drawings. [Embodiment] The first embodiment of the sewing machine driving mechanism assembly of the present invention is improved, as shown in the drawings and the embodiment, including a bracket plate 20 whose one end is fixed on the sewing machine head, and a bracket plate 20 which is fixed on the machine plate. The drive motor 50 at the other end is a first gear 丨 5 fixed on the main shaft 丨 2 of the sewing machine head, and one is fixed to the motor.

〇48-013TWP.ptd Page 6 1234594 V. Description of the invention (3) The second gear 40 on the 50 shaft 51 and a drive belt 30 which achieves the interlocking relationship between the first and second gears 15 and 40, among which, In the present embodiment, the bracket plate 20 is locked to the plurality of fixing holes 110 on the panel 10 of the machine head 10 with a square frame 17 and a plurality of screws 23. Basically, the first end of the bracket plate 20 has A large circular hole 21 and most of the small fixing holes 25 on the outer periphery, and a small circular hole 2 1 a on the center of the second end of the motor shaft 5 1 can be extended, and the outer periphery is smaller The majority of the fixed circular holes 22 and the long arc-shaped holes 2 2 A ′ provided around the fixed circular holes 22 thus fix the cooling fan 13, the sleeve 14, and the first gear 15 on the main shaft 12 of the machine head. The handwheel 16 can be fixed on the convex shaft 152 of the first gear 15 through the central hole 170 of the frame 17 and the large circular hole 21 of the bracket plate 20 as shown in FIG. 4. , Until the motor 5 0 is held by the flange 5 4 of the end plate 5 3 and is held in the center hole 2 1 A of the second end of the bracket plate 20, and then the majority of the screws pass through the fixing hole 22 It is fixed on a plurality of fixing holes 52 on the periphery of the flange 54 so that the motor is stably locked on the bracket plate 20, so that the motor 50 and the main shaft of the sewing machine head 2 are mechanically fixed and transmitted. The transmission of the pulley and the mechanical connection and fixing of the bracket plate make the complicated parts of the sewing machine driving mechanism simple and beautiful, which is one of the main characteristics of the improved sewing machine driving mechanism assembly of the present invention. Danwai 'In the first embodiment of the present invention, four screw holes 27 can be provided on the two horizontal end faces of the bracket plate 20 || to the fixed end, so as to fix the 90-degree arc-shaped mesh plate 70 on On top of this, a protective cover 60 is provided on the outside of the bracket plate 20, the first and second gears 5 and 40 to protect the housing of the motor 50 from being hit, as shown in Figures 2 and 3. Show. It can also be seen from FIGS. 1 and 4 that the handwheel 16 protrudes beyond the bracket plate 20 and the protective cover 60 to facilitate sewing.

〇48-013TWP.ptd Page 7 1234594 V. Description of the invention (4) The initial machine operator selects the specific position of the main shaft of the sewing machine during sewing operations. As shown in FIGS. 5 and 7, the second embodiment of the present invention has the same general structure as the first embodiment, except that the hand wheel 16 is moved to the sewing machine base in this embodiment. As shown in Figures 6 and 7, the first gear 15A in this embodiment does not have a convex shaft 152. Instead, the convex shaft 152 is changed to a shaft hole 153 'and locked by a screw 155 and a washer 154. It is fixed on the main shaft 12 of the machine head, and then the protection cover 6 〇 A is locked and protected with screws 6 3. The rest are the same as in the first embodiment, in which the same components and components are marked with the same reference numbers. Cross-references are provided, and the relevant explanations are omitted. φ The third embodiment of the present invention, as shown in Figures 8 to 丨 丨, has the same general structure as the second embodiment, except that the main head of the sewing machine head of this embodiment is set higher Position, and the main shaft of the sewing machine of the first and second embodiments is set at a lower position, so the bracket plate 20A of this embodiment is a low-inclined rear configuration, as shown in FIG. 9, the bracket The plate 20A also has a plurality of fixing holes 25 on the front end, which are fixed on the front panel 10 of the machine head 10, and a large circular hole 21 through which the first gear 15A can pass and a large circular hole 21 provided on the side. The arc-shaped through hole can be fixed with an arc-shaped ventilation screen 27, and the rear end of the bracket plate 20A also has a plurality of holes 22 for fixing the motor 50 and a central hole for the motor shaft 51 to extend. 21B, the rest of the components are the same as those of the second embodiment, all are marked with the same reference number, and can be compared with each other. In addition, because the structure of the sewing machine head is a conventional technology and is not the focus of the present invention 'The relevant illustrations and descriptions are omitted and should be explained here
