New description: [New technical field] This creation is about an improved structure of a leather bag sewing machine. In particular, it refers to a motor equipped with a variable speed motor. By controlling the rocker arm to be positioned by the motor, the rocker arm can be adjusted. The need for work, whether fixed at any angular position, ensures that it will not fall or move. In particular, the rocker arm can be positioned at a position of 0 degrees on the horizontal plane, making the sewing of the bag more convenient and precise. [Prior Art] The structure of the purse sewing machine of Xijian can be referred to the patent case of "Paper Bag Sewing Machine Structure" No. 88201645. The structure of the patent case is as follows: "The case is driven on the machine platform by the drive shaft. The hook mechanism of the rocker arm base is operated by the drive hook and the constant swing mechanism is arranged in the base, so that the needle plate on the hook is always located at the position of the needle movement, at the base There is a pulley outside and can be slid in the sliding rail of the machine. The U-shaped rocker arm further includes: a rocker arm, which is located between the lower end of the base and the front seat, and has first and second inside The transmission rods are respectively driven by the constant position swinging mechanism and the hook line transmission mechanism in the base, and the other ends are connected with the first and second transmission shafts of the transmission by the universal joint; one actuator is tied to the rocker arm a front seat end portion perpendicular thereto; comprising a retaining block having a first hole position, a long slot hole and second and third holes positioned at left and right of the long slot hole; .M284680 - curved plate, There is a convex tube for the second drive shaft to be inserted into the long slot of the retaining block There are also long slot holes on both sides of the curved plate, which are respectively opposite to the second and third holes of the retaining block, and the curved plate position can be adjusted by screwing the second, second and long slots. After the position of the long slot of the retaining block is fixed, the nut is fixed, and the first and second transmission shafts respectively drive the transmission rod body and the chain in the front seat by the helical gear and the gear; The transmission rod body has one end with a passive helical gear and a helical gear of the transmission, and the other end is a bevel gear that transmits the action part with a bevel gear, and another gear for transmitting the action part of the transmission gear; 'The system is disposed above the front seat, and includes a seat body having a first hole position and a first hole position. The sleeve is sleeved into the first hole position with a gear provided in the middle, and a hook line is arranged. The device is coupled to the sleeve from the first hole position, and the second hole is for the bevel gear to fit and the other end is coupled to a spur gear; a tooth ring is sleeved outside the hook line and meshes with the spur gear. The outer ring is provided with a recessed hole that can be engaged with the ring seat tab, and a front cover can sequentially connect the ring seat and the ring gear. The threader is fixed in front of the seat body, and there is a slot at the top, which is for the frame slot of the needle plate fixed on the ring seat. However, the case is self-reported in its additional case (Announcement No. 47丨476) The following are missing: 1 When using this type of purse sewing machine, the left side of the sewn material is positioned on the hook line, that is, the sewn material must be able to be accommodated with the base and the front seat, such as the sixth case. As shown in the figure, the space between the base and the front seat and the size of the M284680 can be used for the large luggage 1 and is limited in the scope of use of the leather sewing. 2 If the chain drive mechanism is driven by a chain and sprocket drive during the implementation, after a period of use, the chain is loose and unchained due to wear, especially the chain is composed of multiple chains, each The accumulation of wear of the chain will exacerbate this situation. If it does not stretch, it will cause many problems such as jumping stitches, disconnection and noise, and the maintenance cost will increase. 3. Restricted by the knot between the front seat and the actuating part, the distance from the front cover to the rear cover of the #moving part is quite thick, and this part must be inserted into the leather bag of the sewn, and the sewn material still needs to be normal. Therefore, the narrowest width of the sewn seam must be at least greater than this distance. In other words, the purse sewing machine is not used. It is used for leather bags with a width less than this distance, such as flat design bags or small sewing objects. The scope is again limited. In fact, the leather bag sewing machine that I saw can not only improve the linkage mechanism, but also the convenience of the sewing work and the quality of the sewing seam should be the rocker arm. The control of the air pressure flap pushes the rocker arm forward or backwards f between the air pressure and the suction. Therefore, the result of pushing the rocker arm by the air pressure often occurs as follows: 1. When the plastic gasket of the air pressure valve is aging A leak has occurred ^ ^ The rocker cannot be pushed to the position. Or the rocker arm cannot be held in a fixed position, making the operation of the larger leather bag or the luggage box quite inconvenient. 2. Pushed by air pressure, the rocker arm cannot be pushed to the horizontal level with the horizontal plane, and the flap that controls the rocker arm rotation is easily damaged by the high air pressure and the M284680 speed shock. As a result, the time when the rocker is tilted to the position is uncontrollable, and it is easy to fall or slide, which affects the quality of the sewing. 3. Pushing by air pressure, the speed at which the rocker swings is not too slow, or too fast, because the operator controls the valve. Unless experienced senior operators, it takes a long pre-employment training to affect the productivity of the operation. As for the detailed structure, application principle, function and effect of this creation, a complete understanding can be obtained by referring to the following description according to the drawings. [New content] This creation provides an improved structure of the leather bag sewing machine, which makes the swinging of the rocker arm mechanically controlled by the variable speed motor, and cooperates with the use of the omnidirectional gear to make the rocker arm stand still after being placed. The improved structure of the leather bag sewing machine of the present invention is further provided with a power-off device, when the rocker arm swings to a level with the horizontal plane (ie, completely horizontal), the motor power is interrupted, the rocker arm is fixed, and the operation is provided. Staff are convenient for homework. The improved structure of the leather bag sewing machine of the present invention further includes a weighting block at one end of the rocker arm, and the rocking arm can be extremely lightly curved by the weighting block, in addition to reducing power loss, Increase the security of use. The improved structure of the purse sewing machine of the present invention provides a new linkage structure of the rocker arm, which makes the transmission of power more acute and accurate. M284680 [Embodiment] The improved structure of the leather bag sewing machine of the present invention is divided into a rocker arm structure 100, a needle plate seat fixing structure 3〇〇 and a shuttle head rotating structure 400 for the purpose of easy understanding. The figure shows the relationship position of all the structural components, and then the other drawings are partially enlarged. Since the linkage relationship between the drawing and the components is not completely matched, sometimes it is necessary to indicate the relevant positions through several drawings. In addition, in order to make each enlarged view easy to see, the magnification ratio of each drawing is not exactly the same.
