Description

Technical Field

[0001] The invention relates to the technical field of bag opening machine accessories, in particular to a folding knife structure of a bag opening machine. Background Art

[0002] In the clothing processing process, bag opening is an indispensable processing step, which is mainly used to form pockets at specific positions of clothing, which is convenient for carrying small items such as mobile phones and wallets. The process is to first process the bag opening and bag lip separately, and then sew the bag lip to the bag opening to complete the bag opening. The bag opening processing process requires cutting, folding, shaping and sewing the bag lip of the clothing. Cutting is to open an "H" or "Y" shaped slit on the bag opening, folding is to fold the cut bag opening inward to form a flange, and shaping the bag lip is to place the bag lip on the flange, and finally sew. For example, the invention patent with application number CN202010348853.X discloses a bag opening machine for clothing bag opening processing; the invention patent with application number CN202011214831.0 discloses a continuous production clothing bag opening machine.

[0003] The bag folding mechanism is a crucial component of the bag opening machine. It utilizes a folding knife to move the cut edge of the bag opening in all directions or only in the forward and backward directions to complete the bag folding process. However, current folding knives on the market require different sizes to accommodate the bag opening's cuff length before folding. This reliance on multiple knife sizes significantly increases production costs and burdens manufacturers. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a folding knife structure for a bag opening machine.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A folding knife structure for a bag opening machine includes folding knife units that are distributed at intervals and have an action part at the lower part. The folding knife units are arranged between a mounting frame and a fixed plate. The mounting frame is provided with latching teeth at intervals, and the folding knife units are arranged in tooth grooves between the latching teeth.

[0007] Preferably, the folding knife unit is provided with a folding knife plate, and the folding knife plate and the locking teeth are arranged in an alternating manner.

[0008] Preferably, the hook on the folding knife plate is clamped on the mounting frame.

[0009] Preferably, the folding knife unit is detachably arranged in the tooth groove.

[0010] Preferably, the thickness of the folding knife unit is less than 2.5MM.

[0011] Preferably, a spacing groove is provided between the folding knife units, and the folding knife units arranged front and back relative to each other are staggered and engaged with each other through the spacing groove.

[0012] The beneficial effects of the present invention are:

[0013] 1. Multiple folding knife units are spaced between the mounting frame and the fixed plate to form a folding knife for folding the flanging. The length of the folding knife can be adaptively adjusted by adjusting the number of folding knife units between the mounting frame and the fixed plate to meet the needs of folding bags of different sizes, while reducing the production cost of the enterprise.

[0014] 2. By arranging the front and rear folding knife units relatively to each other to form folding knives that are relatively distributed front and back, and by staggering the folding knife units with spacing grooves to engage the folding knives, the width of the two relatively arranged folding knives can be reduced, so that the folding knife can pass through the bag opening more smoothly and the folding movement width of the folding knife on the bag opening flange can be increased, that is, the flange can be smoothed better, making the folded edge of the pocket flatter. At the same time, it can also adapt to the folding processing of smaller-sized pockets, so that the folding knife has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0024] like Figures 1 to 6 As shown, a folding knife structure of a bag opening machine includes folding knife units 1 that are distributed at intervals and have an acting part 11 at the lower part. The acting part 11 and the folding knife unit 1 are an integrally formed structure. The acting part 11 is used to abut and fold the flap of the bag. The thickness of the folding knife unit 1 is less than 2.5MM, and the folding knife unit 1 is arranged between the mounting frame 3 and the fixed plate 4. The mounting frame 3 and the fixed plate 4 are detachably mounted on each other. A plurality of the folding knife units 1 are mounted and fixed in parallel with each other between the mounting frame 3 and the fixed plate 4, that is, a plurality of the folding knife units 1 are arranged at intervals between the mounting frame 3 and the fixed plate 4 to form a folding knife for folding the flap. The folding knife can then be lifted and lowered and displaced in parallel by connecting a driving mechanism to the mounting frame 3 or the fixed plate 4.

[0025] Furthermore, the mounting frame 3 is provided with latch teeth 31 at intervals, and the folding knife unit 1 is arranged in the tooth groove 32 between the latch teeth 31. Specifically, the folding knife unit 1 is provided with a folding knife plate 12, and the folding knife plate 12 is staggered with the latch teeth 31, thereby distributing the folding knife units 1 at intervals between the mounting frame 3 and the fixed plate 4.

[0026] The hook 13 on the folding knife plate 12 is clamped on the installation frame 3, and the folding knife unit 1 is clamped to the upper end of the installation frame 3 through the hook 13 to improve the stability of the folding knife unit 1 during installation and use.

[0027] The folding knife unit 1 can be detachably arranged in the tooth groove 32. By adjusting the number of the folding knife units 1 arranged between the mounting frame 3 and the fixing plate 4, the length of the folding knife can be adaptively adjusted to meet the use requirements of folding bag processing of pockets of different sizes. At the same time, it avoids the need to equip folding knives of multiple sizes, thereby reducing the production cost of the enterprise.

[0028] A spacing groove 2 is provided between the folding knife units 1, and the folding knife units 1 arranged opposite to each other in the front and rear directions are staggered and engaged with each other through the spacing groove 2 to form folding knives relatively distributed in the front and rear directions, that is, this embodiment can form a front folding knife and a rear folding knife for folding the flaps of pockets in the front and rear directions.

[0029] refer to Figure 5 、 Figure 6As shown, before the front folding knife and the rear folding knife are folded over the flange, their folding knife units 1 are staggered and engaged with each other, and then the folding knife units 1 of the folding knife are staggered and engaged with each other through the spacing groove 2 to reduce the width of the two relatively set folding knives, that is, the folding knife width L1 formed between the front folding knife and the rear folding knife in this embodiment is narrower. At this time, the front folding knife and the rear folding knife can pass through the bag opening more smoothly.

[0030] Figure 6 This is the state of the front folding knife and the rear folding knife after folding the flange. At this time, the moving width L2 of the front folding knife and the rear folding knife is wider, and then by increasing the folding movement width of the folding knife on the bag opening flange, the flange can be better smoothed, making the folded flange of the pocket flatter. At the same time, it can also adapt to the folding processing of smaller-sized pockets, so that the folding knife has a wider range of applications.

[0031] Furthermore, the folding knife unit 1 of this embodiment can also be arranged on the left and right sides to form a left folding knife and a right folding knife for folding the flange.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
