Description

Technical Field

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

[0002] In the garment manufacturing process, the pocket opening machine is an essential auxiliary processing machine. It is mainly used to form pockets in specific positions of the garment to facilitate carrying small items such as mobile phones and wallets. The current practice is to process the pocket opening and the pocket lip separately first, and then sew the pocket lip onto the pocket opening to complete the pocket opening.

[0003] During the bag opening processing, the bag opening needs to be cut and folded. The cut bag opening is then folded into the material setting window of the outer pressure frame of the material setting device using a folding knife to form a folded edge. However, during the retraction process, the folded edge of the bag opening is easily pulled back. At the same time, since the bag opening fabric itself has a certain degree of elasticity, the bag opening is still prone to springing back after folding without being clamped, which affects the folding effect of the bag opening and the overall pattern.

[0004] The existing method to solve the above problem is to set up a clamp (such as a clamp made of manganese steel sheet). By applying force to the clamping end of the clamp, the clamping end can be raised and moved away from the fixed material window. Then, the folding knife is used to fold the bag opening so that the folded edge is located between the fixed material window and the clamping end. Subsequently, the elasticity of the clamp itself is used to rebound and hold the folded edge of the bag opening, thereby preventing the folded edge from being pulled out when the folding knife retracts.

[0005] However, the clamping of the bag opening flange by the clips mainly relies on the elasticity of the clips themselves. As the clips are used for a long time, their elasticity will inevitably gradually decrease, causing the clips to be unable to effectively clamp and fix the bag opening flange, thus affecting the quality of subsequent bag opening processing. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bag opening clamping mechanism for a bag opening machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A bag opening clamping mechanism for a bag opening machine includes an outer pressure frame for supporting the fabric below. The outer pressure frame has a fixed material window. The bottom of the outer pressure frame has a front clamping piece and a rear clamping piece that are rotatably arranged. The front clamping piece and the rear clamping piece are respectively provided with a front clamping end and a rear clamping end corresponding to the front and rear edges of the fixed material window. The rear clamping piece is fixed to the front clamping piece and connected to a drive plate.

[0009] Preferably, the drive plate is driven to rotate and swing by a drive cylinder fixed on the outer pressure frame.

[0010] Preferably, the drive plate is rotatably mounted on a hinge block fixed on an outer pressure frame, and a drive block for driving the drive plate to rotate and swing is connected to the output end of the drive cylinder.

[0011] Preferably, the hinge block is provided with an adjustment groove, and the drive cylinder is installed on the hinge block in an adjustable manner along the length of the adjustment groove.

[0012] Preferably, the drive plate has an adjustment groove two, and the front clamp is adjusted and installed on the drive plate along the length direction of the adjustment groove two.

[0013] Preferably, the rear clamping plate is provided with symmetrically distributed ear pieces, which are located between the front clamping end and the rear clamping end and correspond to the left and right edges of the material setting window.

[0014] Preferably, the front clamping end and the rear clamping end are respectively arranged along the length direction of the front and rear edges of the material fixing window.

[0015] Preferably, the front clamp is fixed with a connecting plate and an adjusting plate, and the rear clamp is fixed to the connecting plate by the adjusting plate.

[0016] Preferably, the adjusting plate has an adjusting groove three, and the rear clamp is adjusted and installed on the adjusting plate along the length direction of the adjusting groove three.

[0017] This utility model also discloses a bag opening flange clamping mechanism for a bag opening machine, including an outer pressure frame for supporting the fabric below. The outer pressure frame has a material fixing window. The bottom of the outer pressure frame has a front clamp and a rear clamp. The rear clamp is fixed to the front clamp and connected to a connecting block. The front clamp and the rear clamp are located below the outer pressure frame and are pressed against the front and rear edges of the material fixing window by the connecting block.

[0018] The beneficial effects of this utility model are:

[0019] 1. By rotating and setting the front and rear clamping pieces at the bottom of the outer pressure frame, when the front and rear clamping pieces are not driven, they are spaced and engaged with the edge of the fixed material window, thereby turning the bag opening into the fixed material window. Subsequently, by driving the front and rear clamping pieces to rotate to press the front and rear edges of the fixed material window, the turned-up edge of the bag opening is clamped, thereby achieving fixed and limited positioning of the turned-up edge of the bag opening to ensure the quality of the bag opening processing.

[0020] 2. The front and rear clamps are rotated and pressed together by an external drive, which makes the pressing force of the front and rear clamps greater and can be more evenly flattened on the front and rear edges of the material window, thereby improving the pressing and fixing effect of the flange and ensuring the reliability of subsequent bag opening processing.

[0021] 3. By providing an adjustment groove three on the adjustment piece, the rear clip can be adjusted and fixed in the front and back direction along the adjustment groove three, thereby adapting to the pressing and fixing of bag openings of different sizes. This improves the applicability of pressing bag openings of different sizes and reduces the inventory cost and replacement time cost. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] 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. Example

[0035] like Figures 1-5 As shown, this embodiment discloses a bag opening folding clamping mechanism for a bag opening machine, including an outer pressure frame 1 for supporting the fabric below. The outer pressure frame 1 has a fixed material window 11 for folding the bag opening, and then the cut bag opening is folded into the fixed material window 11 by an external folding knife to form a folded edge.

[0036] The bottom of the outer pressure frame 1 is provided with a rotating front clamp 2 and a rear clamp 3. The rear clamp 3 is located inside the front clamp 2. The front clamp 2 and the rear clamp 3 are respectively provided with a front clamping end 21 and a rear clamping end 31 corresponding to the front and rear edges of the material fixing window 11. The front clamping end 21 and the rear clamping end 31 are located below the material fixing window 11. Thus, when the front clamp 2 and the rear clamp 3 are not driven to rotate, that is, when the front clamp 2 and the rear clamp 3 are held in the initial position, the front clamp 2 and the rear clamp 3 are spaced and engaged with the edge of the material fixing window 11 so that the bag opening can be turned inward into the material fixing window 11.

[0037] The front clamping end 21 and the rear clamping end 31 are respectively arranged along the length direction of the front and rear edges of the fixed material window 11. When the front clamping piece 2 and the rear clamping piece 3 are driven to rotate close to the fixed material window 11, the front clamping end 21 and the rear clamping end 31 are pressed against the front and rear edges of the fixed material window 11 to clamp and tighten the flanging of the bag opening, thereby achieving fixed and limited positioning of the flanging of the bag opening to avoid the flanging springback affecting the bag opening processing and to ensure the subsequent processing quality of the bag opening.

[0038] Furthermore, the rear clamp 3 is fixed to the front clamp 2. Specifically, a connecting plate 22 and an adjusting piece 23 are fixed on the front clamp 2. The connecting plate 22 is fixedly connected to the front clamp 2, and the adjusting piece 23 is fixedly connected to the connecting plate 22. The rear clamp 3 is fixed to the connecting plate 22 through the adjusting piece 23. That is, the rear clamp 3 is installed on the front clamp 2 through the connecting plate 22 and the adjusting piece 23.

[0039] The adjusting plate 23 has an adjusting groove 231. The rear clamping plate 3 is adjusted and installed on the adjusting plate 23 along the length of the adjusting groove 231. The installation position of the rear clamping plate 3 can be adjusted back and forth by adjusting the adjusting groove 231 to adapt to the pressing and fixing of bag openings of different sizes. This improves the applicability of pressing bag openings of different sizes. In this way, a set of front clamping plate 2 and rear clamping plate 3 can meet the processing of bag openings of most sizes, reducing the inventory cost and replacement time cost.

[0040] The rear clamping piece 3 and the front clamping piece 2 are connected to the drive plate 15. The drive plate 15 is driven to rotate and swing by the drive cylinder 12 fixed on the outer pressure frame 1. That is, the front clamping piece 2 and the rear clamping piece 3 are rotated and swung by the action of the drive cylinder 12, so as to control the front clamping end 21 and the rear clamping end 31 to press together or move away from the front and rear edges of the fixed material window 11.

[0041] By driving the cylinder 12 to achieve the rotation, swinging, pressing, and flanging action of the front clamping piece 2 and the rear clamping piece 3, compared with the existing design that uses the spring characteristics of the clamping piece itself to hold the bag opening, this embodiment drives the front clamping piece 2 and the rear clamping piece 3 to rotate and swing by driving the cylinder 12, so that the pressing force of the front clamping piece 2 and the rear clamping piece 3 is greater and more reliable. This allows them to be more evenly flattened on the front and rear edges of the material setting window 11, thereby improving the pressing and fixing effect of the flanging and ensuring the reliability of subsequent bag opening processing.

[0042] The drive plate 15 is rotatably mounted on the hinge block 14 fixed on the outer pressure frame 1. The drive plate 15 is provided with a hinge end 151 adapted to the hinge block 14. The hinge end 151 is rotatably connected to the hinge block 14 through a rotating shaft.

[0043] The drive cylinder 12 is fixedly installed on the hinge block 14. The output end of the drive cylinder 12 is connected to a drive block 13 for driving the drive plate 15 to rotate and swing. The drive block 13 is rotatably connected to one end of the drive plate 15, and the other end of the drive plate 15 is fixed to the front clamp 2.

[0044] Furthermore, the hinge block 14 is provided with an adjustment groove 141. The drive cylinder 12 is installed on the hinge block 14 by adjusting up and down along the length of the adjustment groove 141. The height position of the drive cylinder 12 is adjusted up and down by adjusting the adjustment groove 141 to facilitate the adjustment and installation of the front clamping piece 2 and the rear clamping piece 3. This allows for more flexible adjustment of the rotation and swing angle of the front clamping piece 2 and the rear clamping piece 3, ensuring that the front clamping end 21 and the rear clamping end 31 can be more evenly flattened on the front and rear edges of the fixed material window 11 after adjustment. This makes the pressing and flanging operation of the clamping end 21 and the rear clamping end 31 more reliable.

[0045] To further improve the flexibility and convenience of adjusting the front clamp 2 and the rear clamp 3, an adjustment groove 2 152 is provided on the drive plate 15. The front clamp 2 is adjusted and installed on the drive plate 15 along the length direction of the adjustment groove 2 152. The front clamp 2 and the rear clamp 3 are installed in a forward and backward position by adjusting the adjustment groove 2 152, so as to flexibly adjust the front clamping end 21 and the rear clamping end 31 to be pressed at the front and rear edges of the fixed material window 11 when the front clamp 2 and the rear clamp 3 are rotated and pressed together, thereby improving the flexibility and convenience of adjusting and installing the front clamp 2 and the rear clamp 3.

[0046] The rear clamping piece 3 is provided with symmetrically distributed ear pieces 32. The ear pieces 32 are located between the front clamping end 21 and the rear clamping end 31 and correspond to the left and right edges of the fixed material window 11, so as to press the left and right positions of the bag opening flange through the ear pieces 32. Example

[0047] like Figures 6-8 As shown, compared with Embodiment 1, the front clamp 2 and the rear clamp 3 are arranged parallel to the outer pressure frame 1 in this embodiment.

[0048] Specifically, it includes an outer pressure frame 1 for supporting the fabric below. The outer pressure frame 1 has a material fixing window 11. The bottom of the outer pressure frame 1 has a front clamping piece 2 and a rear clamping piece 3. The front clamping piece 2 and the rear clamping piece 3 are located below the outer pressure frame 1. The rear clamping piece 3 is fixed to the front clamping piece 2 and connected to the connecting block 16. A drive cylinder 12 is fixedly installed on the outer pressure frame 1. The output end of the drive cylinder 12 is connected to the connecting block 16. The drive cylinder 12 drives the connecting block 16 to move up and down, thereby controlling the up and down movement of the front clamping piece 2 and the rear clamping piece 3. That is, the connecting block 16 drives the front clamping end 21 and the rear clamping end 31 to press upwards and close to the front and rear edges of the material fixing window 11, so as to realize the pressing operation of the bag opening. Example

[0049] like Figures 9-10 As shown, in this embodiment, the bag opening flange clamping mechanism of the bag opening machine does not have an ear piece 32.

[0050] When processing bag openings that require knotting, i.e., the left and right ends of the bag opening in the garment to be processed do not have triangles for folding the bag, but only the front and back of the bag opening are folded, the ear piece 32 is not provided on the back clip 3 to meet the processing needs of bag openings that require knotting in this embodiment; and by removing the ear piece 32, the processing needs of larger-sized knotted bag openings are met, making the application range of bag opening processing in this embodiment wider. Example

[0051] Compared with Example 2, this embodiment adds a gasket to the output end of the drive cylinder 12.

[0052] The output end of the driving cylinder 12 passes through the front clamping piece 2. The gasket is located below the front clamping piece 2. One end of the front clamping piece 2 and the rear clamping piece 3 are fixed on the outer pressure frame 1. When it is necessary to drive the front clamping piece 2 and the rear clamping piece 3 upward, the driving cylinder 12 is activated to move the gasket upward to abut against the front clamping piece 2, thereby driving the front clamping piece 2 and the rear clamping piece 3 upward so that the front clamping end 21 and the rear clamping end 31 are pressed upward against the front and rear edges of the fixed material window 11, thereby realizing the pressing action of the bag opening flange.

[0053] 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.
