Description

Technical Field

[0001] This utility model relates to the technical field of bag opening machine accessories, and in particular to a flanging clamping mechanism for a bag opening machine. Background Technology

[0002] In garment manufacturing, opening pockets is an essential step, primarily used to create pockets in specific locations on clothing for carrying small items such as mobile phones and wallets. The process involves first separately processing the pocket opening and the pocket lip, then sewing the lip onto the opening to complete the opening. The processing of the pocket opening requires cutting, folding, shaping the lip, and sewing. Cutting involves creating an "H" or "Y" shaped slit at the pocket opening; folding involves folding the cut opening inwards to form a folded edge; shaping the lip involves placing the lip on the folded edge; and finally, sewing. For example, utility model patent application number CN202010348853.X discloses a pocket-opening machine for garment pocket processing; utility model patent application number CN202011214831.0 discloses a continuous production garment pocket-opening machine.

[0003] The folding mechanism is an important component of the bag opening machine. It uses a folding knife to fold the cut edge of the bag opening in all directions or only in the front and back directions to fold the edge. The folded edge is fixed by a clamping plate so that the folded edge of the bag is not easily pulled back during the retraction of the folding knife. The bag is then moved to the sewing station for sewing.

[0004] In order for the folded edge to be folded and sewn onto the garment piece, a certain sewing gap needs to be left between the clip and the folded edge. As a result, the clip cannot completely cover and press against the folded edge. However, the more area the clip presses against and holds the folded edge, the better the folding and shaping effect of the pocket, and the better the overall shape of the pocket opening after subsequent sewing. Therefore, how to improve the folding and shaping effect of the pocket while ensuring that the folded edge can be sewn normally is an issue that urgently needs to be improved in the current market. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flanging clamping mechanism for a bag opening machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flanging clamping mechanism for a bag opening machine includes an outer pressure frame with a material setting window. A front clamping piece and a rear clamping piece, corresponding to the front and rear long sides of the material setting window, are raised and lowered below the outer pressure frame. The outer pressure frame is equipped with a first driving cylinder for driving the front clamping piece to move back and forth and a second driving cylinder for driving the rear clamping piece to move back and forth.

[0008] Preferably, the outer pressure frame is provided with a front slide rail extending in the front-rear direction, and the front clamp is connected to a front slide plate that is slidably disposed on the front slide rail.

[0009] Preferably, a lifting cylinder is provided on the front sliding plate, and the lifting cylinder is connected to the front clamping plate via a front connecting plate.

[0010] Preferably, the outer pressure frame is provided with a rear slide rail extending in the front-to-back direction, and the rear clamp is connected to a rear slide plate that is slidably disposed on the rear slide rail.

[0011] Preferably, the rear slide plate is provided with a second lifting cylinder, which is connected to the rear clamp plate via a rear connecting plate.

[0012] The beneficial effects of this utility model are:

[0013] By connecting the front and rear clamps with separate front and rear drives, the front and rear clamps can extend and retract relative to the front and rear long sides of the fixed material window. During bag folding, the front clamp can move backward and the rear clamp can move forward to increase the area of ​​the front and rear clamps that press and hold the folded edge, and improve the folding and shaping effect. When sewing is required, the front clamp moves forward and the rear clamp moves backward to provide a sewing gap for the sewing operation, thereby ensuring that the pocket can be sewn normally.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-5 As shown, a flanging clamping mechanism for a bag opening machine includes an outer pressure frame 1 with a fixed material window 11. A front clamping piece 2 and a rear clamping piece 3, corresponding to the front and rear long sides of the fixed material window 11, are raised and lowered below the outer pressure frame 1. The front clamping piece 2 and the rear clamping piece 3 can move upward and press against the outer pressure frame 1, thereby realizing the cooperation of the front clamping piece 2 and the rear clamping piece 3 to press and clamp the folded edge.

[0023] The outer pressure frame 1 is provided with a drive cylinder 21 that drives the front clamping piece 2 to move back and forth. The output shaft of the drive cylinder 21 is connected to the front clamping piece 2. Specifically, the outer pressure frame 1 is provided with a front slide rail 12 extending in the front and back direction. The front clamping piece 2 is connected to a front slide plate 22 that is slidably set on the front slide rail 12. The drive cylinder 21 drives the front slide plate 22 to slide back and forth along the front slide rail 12, so as to drive the front clamping piece 2 to move back and forth synchronously.

[0024] The outer pressure frame 1 is also provided with a second driving cylinder 31 that drives the rear clamping piece 3 to move back and forth. The output shaft of the second driving cylinder 31 is connected to the rear clamping piece 3. Specifically, the outer pressure frame 1 is provided with a rear slide rail 13 extending in the front and rear direction. The rear clamping piece 3 is connected to a rear slide plate 32 that is slidably set on the rear slide rail 13. The second driving cylinder 31 drives the rear slide plate 32 to slide back and forth along the rear slide rail 13, so as to drive the rear clamping piece 3 to move back and forth synchronously.

[0025] That is, by driving the front clamp 2 and the rear clamp 3 connected in the front and rear respectively, the front clamp 2 and the rear clamp 3 can move back and forth relative to the front and rear long sides of the fixed material window 11. Then, during the bag folding process, the front clamp 2 can move backward and the rear clamp 3 can move forward. Then, the front clamp 2 and the rear clamp 3 are driven to move upward to press and hold the folded edge, so that the front clamp 2 and the rear clamp 3 cooperate with each other to increase the area of ​​the front clamp 2 and the rear clamp 3 pressing and holding the folded edge, and improve the effect of folding and shaping.

[0026] When sewing is required, the front clip 2 moves forward and the rear clip 3 moves backward, meaning the front clip 2 and the rear clip 3 move away from each other to provide a sewing gap for the sewing operation, thereby ensuring that the pocket can be sewn normally.

[0027] Furthermore, the front clip 2 and the rear clip 3 can be independently controlled by the drive cylinder 21 and the drive cylinder 31 respectively. That is, the front clip 2 can move forward first to sew the front edge, and then the rear clip 3 can move backward to sew the rear edge (the rear clip 3 can also move backward first, and then the front clip 2 can move forward), thereby meeting the processing requirements of different pocket production processes.

[0028] A lifting cylinder 23 is provided on the front slide plate 22. The lifting cylinder 23 is connected to the front clamping plate 2 via the front connecting plate 24. The output shaft of the lifting cylinder 23 passes through the front slide plate 22 and is connected to the connecting plate 24. The lifting cylinder 23 controls the lifting displacement of the front clamping plate 2 via the connecting plate 24.

[0029] The rear slide plate 32 is equipped with a second lifting cylinder 33. The second lifting cylinder 33 is connected to the rear clamping plate 3 via a rear connecting plate 34. The output shaft of the second lifting cylinder 33 passes through the rear slide plate 32 and is connected to the connecting plate 34. The second lifting cylinder 33 controls the lifting displacement of the rear clamping plate 3 via the connecting plate 34.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
