[0046] like Figures 1 to 7As shown, the utility model provides an automatic sewing device for woven bags with a tightening function, comprising: a support base 1, a transfer table 2, a sewing machine 6, an upper pressing and pulling component 4 and a lower pressing and pulling component 5.

[0047] The support base 1 is provided with a linear guide rail 11 on the upper part; the support base 1 serves as the bottom foundation of the entire device, carrying all components and ensuring its stability.

[0048] The transfer table 2 is arranged on the linear guide rail 11 and moves along the linear guide rail 11. The woven bag 7 is arranged on the transfer table 2.

[0049] The transfer table 2 carries the woven bag 7, and the woven bag 7 is accurately transmitted and positioned through the coordinated work of the transfer table motor 22, the guide wheel 25, the synchronous belt 26 and the belt motor 24; after the bag mouth is sewn, the conveyor belt can move the woven bag to the next workstation; the transfer table motor 22 can drive the transfer table 2 to move left and right through the synchronous belt 26.

[0050] The upper pressing and pulling component 4 and the lower pressing and pulling component 5 are arranged relative to each other up and down, and the upper and lower rollers 44 are arranged obliquely. After rotation, an oblique force is provided, which can be decomposed into a forward force and a rightward force. The forward force can tighten the seal of the woven bag 7.

[0051] The sewing machine 6 is provided with one side of the upper pressing and pulling component 4 and the lower pressing and pulling component 5 for sewing the woven bag opening 71 .

[0052] When the woven bag 7 moves horizontally to the right, it will move obliquely forward under the action of the knurled roller 44, thereby pulling the tube yarn woven bag 7 to move toward the upper and lower pressing and pulling assembly 5 until the tube yarn is close to the front baffle 47. After the front end of the woven bag 7 is exposed from the right side of the upper and lower pressing and pulling assembly 5, it immediately enters the sewing machine 6 to complete the sewing, ensuring the compact sewing of the tube yarn woven bag 7.

[0053] The transfer table 2 includes: a transfer table frame 21 , a transfer table motor 22 , a guide wheel 25 , a synchronous belt 26 , a conveyor belt 27 , a belt 23 and a belt motor 24 .

[0054] The turntable 2 is arranged on the upper part of the base frame, and two guide wheels 25 are arranged on the lower part of the base frame. A synchronous wheel is arranged on the rotating shaft of the turntable motor 22. The synchronous belt 26 passes around the two guide wheels 25 and the synchronous wheel respectively, and the two ends of the synchronous belt 26 are respectively fixed on the two ends of the support seat 1.

[0055] The belt 23 is arranged on the upper part of the turntable base frame 21 , and the belt motor 24 rotates through the belt 23 , thereby driving the conveyor belt 27 to rotate.

[0056] The upper pressing and pulling component 4 includes: a roller 44 , a cylinder 41 , a front baffle 47 , a chain 45 and a mounting seat 46 .

[0057] Several of the rollers 44 are tiltedly arranged on a mounting seat 46 , and two coaxial sprockets 43 are arranged on the rollers 44 . Two adjacent rollers 44 are connected and driven by a chain 45 , and a motor 42 is connected to a roller 44 at one end through the chain 45 ; the chain 45 is used for transmission to realize power transmission between the rollers 44 .

[0058] A ball bearing is provided between the roller 44 and the mounting seat 46 , and is installed between the roller 44 and the mounting seat 46 to reduce friction and improve the smoothness and durability of the rotation of the roller 44 .

[0059] The roller 44 is provided with a pattern for increasing friction, which effectively prevents the woven bag 7 from sliding during the tightening process, ensures the tightening effect, and avoids the problem of wrinkles at the bag opening.

[0060] The extending rod of the cylinder 41 is fixed to the mounting seat 46 to provide power for the upper pressing and pulling component 4 to move up and down; it provides power for the upper pressing and pulling component 4 to move up and down, and cooperates with the up and down movement of the lower pressing and pulling to achieve the tightening and release of the woven bag mouth 71.

[0061] The upper pressing and pulling assembly 4 and the lower pressing and pulling assembly 5 are symmetrically arranged and have the same structure. The standardized and modular design, such as the upper pressing and pulling assembly 4 and the lower pressing and pulling assembly 5 are symmetrically arranged and have the same structure, not only simplifies the assembly and debugging process of the equipment, but also reduces the difficulty of subsequent maintenance and replacement of parts, and improves production efficiency.

[0062] The front baffle plate 47 is fixed on the mounting plate and arranged in front of the roller 44 to block the woven bag 7. The woven bag 7 is blocked during the tightening process to prevent the woven bag 7 from excessive movement or deviation.

[0063] The lower part of the upper pressing and dragging component 4 is provided with a chain stopper 48 for blocking the chain 45. The chain stopper 48 prevents the chain 45 from derailing during operation, thereby improving the stability and safety of the transmission system.

[0064] The roller 44 is inclined relative to the vertical line, and the range of ∠a is 5 to 20 degrees. When the inclination angle is set, the roller 44 rotates obliquely forward, which can provide a forward component force to tighten the woven bag opening 71; and provide a rightward component force to drag the bag opening to move toward the sewing machine 6. The angle is related to the sprocket spacing. If the angle is too large, the spacing is large and the space occupied is large; if the angle is too small, the pulling function will be affected.

[0065] The working method is that the turntable 2 transports the bobbin yarn woven bag 7 to Figure 3In the position shown, that is, when the right edge of the woven bag 7 reaches the center axis of the roller 44 on the far left, the cylinder 41 of the upper and lower pressing and pulling assembly 5 extends to clamp the woven bag 7, and at the same time the motor 42 rotates, and the lateral speed of the roller 44 is consistent with the lateral movement speed of the turntable 2. The upper and lower pressing and pulling assembly firmly presses the woven bag mouth 71, and the knurled roller 44 ensures that there is a large friction between the roller 44 and the woven bag 7, and it is not easy to produce relative sliding. During the lateral movement, the woven bag 7 will move obliquely forward under the action of the knurled roller 44, thereby pulling the bobbin yarn woven bag 7 to move toward the upper and lower pressing and pulling assembly 5 until the bobbin yarn is close to the front baffle 47. After the front end of the woven bag 7 is exposed from the right side of the upper and lower pressing and pulling assembly, it immediately enters the sewing machine 6 to complete the sewing, ensuring the compact sewing of the bobbin yarn woven bag 7.

[0066] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
