[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0030] It should be noted that similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0031] This embodiment mainly elaborates on the wire outlet cutting device of the drawstring of a non-woven fabric drawstring bag making machine that can effectively reduce the frequency of cutting knife replacement, as follows:

[0032] As Figure 1-6 shown, the wire outlet cutting device of the drawstring of a non-woven fabric drawstring bag making machine includes a workbench 1 provided with a processing port 1a, an upper mounting frame 2 fixed above the workbench 1, an Okinawa cutting assembly installed on the mounting frame, a pressing assembly slidably installed on the mounting frame, an ultrasonic module 3 located in the processing port 1a, a slide rail 4 slidably installed below the workbench 1, a lower mounting frame 5 fixedly connected to the slide rail 4, two slide bars 6 provided on the lower mounting frame 5, and a chassis 7 slidably installed on the two slide bars 6. The ultrasonic module 3 is fixed on the chassis 7.

[0033] Preferably, the workbench 1 and the lower mounting frame 5 are threadedly connected with a screw 8. By rotating the screw 8, the workbench 1 can be driven to translate along the slide rail 4.

[0034] In this embodiment, the mounting frame has an inverted concave structure. A vertical plate 9 is slidably installed on the upper mounting frame 2. The vertical plate 9 can be slidably limited by bolts. The vertical plate 9 is located between the upper mounting frame 2 and the workbench 1, and the pressing assembly is fixed on the vertical plate 9.

[0035] As Figure 2-5As shown, the processing port 1a divides one side of the workbench 1 into a pressing part 1b that can be pressed together with the pressing plate 13, and the other side into an Okinawa part 1c. The pressing assembly is suspended above the pressing part 1b. An Okinawa plate 11 is slidably installed on the Okinawa part 1c. The Okinawa plate 11 can be slidably limited by bolts. The Okinawa plate 11 extends out of the Okinawa part 1c. A rope cutting port 10 is formed between the ultrasonic module 3 and the side wall of the Okinawa plate 11. An Okinawa port 11a is provided on the Okinawa plate 11, and a partition strip 11b is provided on the Okinawa plate 11. The partition strip 11b separates the rope cutting port 10 from the Okinawa port 11a. Preferably, the Okinawa port 11a and the partition strip 11b can be directly provided on the Okinawa part 1c.

[0036] The pressing assembly includes a cylinder one 12 fixed on the vertical plate 9 and a pressing plate 13 installed on the driving rod of the cylinder one 12. The cylinder one 12 can control the pressing plate 13 to fit or move away from the pressing part 1b of the workbench 1 through expansion and contraction.

[0037] The Okinawa cutting assembly includes a cylinder two 14 fixed above the upper mounting frame 2, a pressing block 15 connected to the driving rod of the cylinder two 14, an Okinawa rod 16 slidably installed on the pressing block 15 and limited by bolts, and a cutter 17 slidably installed on the pressing block 15 and limited by bolts. And a recessed acting part 16a is provided at the lower end of the Okinawa rod 16.

[0038] When the cylinder two 14 drives the pressing block 15, the Okinawa rod 16 and the cutter 17 to move downward, the pressing block 15 can be attached to the ultrasonic module 3 and weld the drawstring 19 between the drawstring 19 and the bag body 18 of the drawstring 19 bag. And the Okinawa rod 16 is inserted into the Okinawa port 11a. The acting part 16a of the Okinawa rod 16 acts to pull down the drawstring 19, extending the length of the drawstring 19 pulled out of the bag body 18. And the cutter 17 is inserted into the rope cutting port 10, and can cut the drawstring 19 located at the rope cutting port 10.

[0039] In this embodiment, the cutter 17 is obliquely arranged, so that during the process of the cutter 17 being inserted into the rope cutting port 10, the contact surface between the cutting edge on the cutter 17 and the drawstring 19 increases, making it more convenient to cut the drawstring 19. And the length by which the Okinawa rod 16 extends beyond the cutter 17 is about half of the length of the drawstring 19 pulled out of the bag body 18 by the acting of the Okinawa rod 16. The sliding arrangement of the Okinawa rod 16 and the cutter 17 enables the length of the drawstring 19 pulled out of the bag body 18 by the acting of the Okinawa rod 16 to be adjustable, and the cutting edge part of the cutter 17 for cutting the drawstring 19 can be replaced by sliding.

[0040] In this application, through the settings of the Okinawa opening 11a and the string-cutting opening 10, when the pressing component presses the previous non-woven fabric drawstring 19 bag and the drawstring 19, the Okinawa rod 16 presses the drawstring 19 down into the Okinawa opening 11a. Due to the settings of the partition strip 11b and the ultrasonic module 3, the drawstring 19 at the string-cutting opening 10 is horizontally attached to the partition strip 11b and the ultrasonic module 3, ensuring that while the cutter 17 inserts into the string-cutting opening 10 to cut the drawstring 19, the cutter 17 will not hit the ultrasonic module 3, effectively reducing the damage probability of the cutter 17, extending the service life of the cutter 17, and reducing the replacement frequency of the cutter 17.

[0041] As Figure 1 , Figure 5 and Figure 6 shown, before the drawstring 19 bag on the bag-making machine enters the wire outlet cutting device, a first punching will be preformed on the continuous bag body 18, that is, side openings 18a are formed on the continuous bag body 18. The drawstring 19 in the folded edge of the continuous bag body 18 passes through the side openings 18a. When the continuous bag body 18 passes through the wire outlet cutting device, the side openings 18a are above the Okinawa opening 11a and the string-cutting opening 10 on the workbench 1. The Okinawa rod 16 and the cutter 17 pull down and cut the drawstring 19 in the side openings 18a, and the pressing block 15 and the ultrasonic module 3 clamp and weld the previous part of the bag body 18 and the drawstring 19 to form a welded part 18b on the continuous bag body 18.

[0042] To ensure that the drawstrings 19 between adjacent bag bodies 18 are cut, a second punching component is slidably installed on one side of the workbench 1. A slideway 20 is fixed on one side of the workbench 1. The pressing part 1b of the workbench 1 is located between the Okinawa part 1c and the slideway 20. The second punching component includes a sliding table 21 slidably and limitedly installed on the slideway 20 by bolts, a cylinder three 22 installed on the sliding table 21, a brush 24 installed on one side of the sliding table 21 and located between the sliding table 21 and the pressing part 1b, and a punching part 23 connected to the driving rod of the cylinder three 22. A lower punching opening 21a is provided on the sliding table 21.

[0043] When the side opening 18a of the continuous bag body 18 is conveyed to correspond to the lower punching opening 21a, the cylinder three 22 can drive the punching part 23 to pass through the side opening 18a and insert into the lower punching opening 21a to perform a second punching on the drawstring 19. The setting of the brush 24 makes the side opening 18a of the continuous bag body 18 pass through the brush 24 before being conveyed to the lower punching opening 21a. The brush 24 sweeps the drawstring 19 and makes the drawstring 19 shift towards the position of the next bag body 18. This can not only ensure that the already cut drawstring 19 will not contact the punching part 23 when the punching part 23 inserts into the lower punching opening 21a, ensuring the length of the already cut drawstring 19, but also punch the pulled-out but not fully cut drawstring 19 to ensure that the drawstrings 19 between adjacent bag bodies 18 are disconnected.

[0044] Preferably, the side wall of the previous bag body 18 where the side opening 18a is located is the front side wall 18c. The position where the punching member 23 acts without cutting off the drawstring 19 acts directly or fits on the front side wall 18c, which can effectively ensure the length of the cut drawstring 19.

[0045] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0046] The above has introduced in detail the drawstring outlet cutting device of the non-woven drawstring bag making machine provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the present invention and its core idea. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
