Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a double clamping mechanism for flipping the bag opening of 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 clamping piece (such as a clamping piece made of manganese steel sheet). In the initial state, the clamping end of the clamping piece is set away from the fixed material window. Then, the folding knife can be used to fold the bag opening so that the folded edge is located between the fixed material window and the clamping end. Subsequently, by applying force to the clamping piece, the clamping end of the clamping piece can be pressed against the edge of the fixed material window to clamp the folded edge of the bag opening, thereby preventing the problem of the folded edge being pulled out when the folding knife retracts.

[0005] However, existing clips are generally driven by a single drive source to press the edge of the material setting window. This can easily lead to the front and rear ends of the clip not fitting well against the edge of the material setting window during pressing. In other words, one side or corner of the clip may not be flat and pressed onto the same plane of the material setting window, causing a part of the clip to be slightly raised after pressing. This results in unstable pressing and clamping effect of the clip, which can easily affect the subsequent processing quality of the bag opening. Summary of the Invention

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

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

[0008] A double clamping mechanism for flipping the bag opening of a bag opening machine includes 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 is provided with a front clamping piece and a rear clamping piece. The outer pressure frame is provided with a driving cylinder for driving the front clamping piece and the rear clamping piece to swing independently. 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 material fixing window.

[0009] Preferably, the device also includes a drive plate 1 connected to the front clamping plate and a drive plate 2 connected to the rear clamping plate. The drive plate 1 is driven to swing by a drive cylinder 1 fixed on the outer pressure frame, and the drive plate 2 is driven to swing by a drive cylinder 2 fixed on the outer pressure frame.

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

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

[0012] Preferably, the second drive plate is rotatably mounted on the second hinge block fixed on the outer pressure frame, and the output end of the second drive cylinder is connected to the second drive plate.

[0013] Preferably, an adjustment plate two is fixed on the rear clamp, and an adjustment groove four is provided on the adjustment plate two. The adjustment plate two is adjusted and fixed to the drive plate two along the length direction of the adjustment groove four.

[0014] The drive plate has an adjustment groove, and the front clamp is installed on the drive plate along the length of the adjustment groove.

[0015] Preferably, the rear clip is provided with a fixing plate, and an adjusting plate for connecting the rear clip is fixed on the fixing plate. The adjusting plate is provided with an adjusting groove, and the rear clip is adjusted back and forth along the length direction of the adjusting groove to be installed on the adjusting plate.

[0016] 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.

[0017] Preferably, the rear clamp is located inside the front clamp, and 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.

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

[0019] 1. By setting front and rear clamping plates at the bottom of the outer pressure frame, and using a drive cylinder to drive the front and rear clamping plates to rotate and swing, the front clamping end and the rear clamping end can be pressed against the front and rear edges of the fixed material window respectively, thereby pressing and clamping the bag opening flange, thus achieving fixed positioning of the bag opening flange. Furthermore, by driving the front clamping end and the rear clamping end to perform pressing action through the drive cylinder, the pressing force of the front and rear clamping plates is greater, and they can be pressed against the front and rear edges of the fixed material window more evenly, thereby improving the stability of flange pressing and clamping, and ensuring the reliability of subsequent bag opening processing.

[0020] 2. By providing an adjustment groove on the hinge block, the installation position of the drive cylinder is adjusted up and down through the adjustment groove. That is, by using the drive cylinder and the drive plate, the angle difference between the front clamping plate and the rear clamping plate is adjusted. Thus, when the front clamping plate and the rear clamping plate swing upward to press against the front and rear edges of the fixed material window, the front clamping end and the rear clamping end can be more evenly pressed against the front and rear edges of the fixed material window. Furthermore, by adjusting the angle difference between the front clamping plate and the rear clamping plate, the front clamping plate and the rear clamping plate can be pressed against the front and rear edges of the fixed material window simultaneously when swinging upward. This ensures that the pressing force of the front clamping end and the rear clamping end is more uniform, making the pressing and clamping of the flange more stable.

[0021] 3. By providing an adjustment groove four on the adjustment plate two, the rear clip can be adjusted and fixed in the front and back direction along the adjustment groove four to adapt to the pressing and fixing of bag opening flanges of different sizes. This improves the applicability of pressing and fixing bag opening flanges of different sizes and reduces the inventory cost and replacement time cost. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0032] 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

[0033] like Figures 1-6 As shown in the figure, this embodiment discloses a double clamping mechanism for flipping the bag opening of 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 flipped edge.

[0034] The bottom of the outer pressure frame 1 is provided with a front clamping piece 2 and a rear clamping piece 3. The rear clamping piece 3 is located inside the front clamping piece 2. The front clamping piece 2 is arranged around the outside of the rear clamping piece 3 on three sides. The front clamping piece 2 and the rear clamping piece 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 respectively arranged along the length direction of the front and rear edges of the material fixing window 11. By the front clamping end 21 and the rear clamping end 31 arranged along the length direction of the front and rear edges of the material fixing window 11, the bag opening flange located at the material fixing window 11 can be better fitted and pressed.

[0035] When the front clamping piece 2 and the rear clamping piece 3 are not driven to press together, that is, when the front clamping end 21 and the rear clamping end 31 are in the initial position below the fixed material window 11, the front clamping piece 2 and the rear clamping piece 3 are spaced together with the edge of the fixed material window 11 so that the bag opening can be turned inside the fixed material window 11.

[0036] The outer pressure frame 1 is equipped with driving cylinders that drive the front clamping piece 2 and the rear clamping piece 3 to swing independently. The driving cylinders include a first driving cylinder 12 and a second driving cylinder 15. Specifically, the outer pressure frame 1 is equipped with a first driving plate 14 connected to the front clamping piece 2 and a second driving plate 17 connected to the rear clamping piece 3. The first driving plate 14 is driven to swing by the first driving cylinder 12 fixed to the outer pressure frame 1, so that the first driving cylinder 12 independently drives the first driving plate 14 and the front clamping piece 2 to swing upwards and press the bag opening flange (also...). This can be understood as pressing the flange corresponding to the front edge of the material setting window 11. The second drive plate 17 is driven to swing by the second drive cylinder 15 fixed on the outer pressure frame 1. The second drive cylinder 15 drives the second drive plate 17 and the rear clamping piece 3 to swing upward and press the flange of the bag opening (which can also be understood as pressing the flange corresponding to the rear edge of the material setting window 11). This achieves the pressing and clamping of the flange of the bag opening, that is, the fixed and limited position of the flange of the bag opening, so as to ensure the stability and reliability of the subsequent bag opening processing.

[0037] By driving cylinder 12 and driving cylinder 25 to drive the front clamping plate 2 and the rear clamping plate 3 to rotate and swing respectively, dual drive control of the front clamping plate 2 and the rear clamping plate 3 is achieved. Compared with the existing single drive source driving clamping plate to press the bag opening, this embodiment drives the front clamping end 21 and the rear clamping end 31 to perform pressing action by driving cylinder 12 and driving plate 25 respectively. This makes the pressing force of the front clamping plate 2 and the rear clamping plate 3 greater, and can more evenly press and flatten the front and rear edges of the fixed material window 11, thereby improving the stability of the pressing and clamping of the flange and further ensuring the reliability of subsequent bag opening processing.

[0038] The drive plate 14 is rotatably mounted on the hinge block 13 fixed on the outer pressure frame 1. The output end of the drive cylinder 12 is connected to the drive plate 14. The drive plate 14 is driven to rotate and swing around the hinge block 13 as the rotation axis by the drive cylinder 12.

[0039] Furthermore, the hinge block 13 is provided with an adjustment groove 131. The drive cylinder 12 is installed on the hinge block 13 along the length of the adjustment groove 131. The installation height of the drive cylinder 12 is adjusted up and down through the adjustment groove 131, so as to adjust the installation angle of the drive plate 14 and the front clamping piece 2 through the drive cylinder 12, thereby adjusting the angle difference between the front clamping piece 2 and the rear clamping piece 3, that is, adjusting the upward swing angle of the front clamping end 21.

[0040] When the front clamping piece 2 and the rear clamping piece 3 are driven to swing upward to press the front and rear edges of the fixed material window 11, the front clamping end 21 and the rear clamping end 31 can be more evenly pressed against the front and rear edges of the fixed material window 11. Furthermore, by adjusting the angle difference between the front clamping piece 2 and the rear clamping piece 3, the front clamping piece 2 and the rear clamping piece 3 can be pressed against the front and rear edges of the fixed material window 11 simultaneously when swinging upward. This ensures that the pressing force of the front clamping end 21 and the rear clamping end 31 is more uniform, making the pressing force on the fixed material window 11 more uniform, and thus making the pressing and clamping of the flange more stable and effective.

[0041] The second drive plate 17 is rotatably mounted on the second hinge block 16 fixed on the outer pressure frame 1. The output end of the second drive cylinder 15 is connected to the second drive plate 17. The second drive cylinder 15 drives the second drive plate 17 to rotate and swing around the second hinge block 16 as the rotation axis.

[0042] Furthermore, an adjustment plate 2 35 is fixed on the rear clamp 3, and an adjustment groove 4 351 is provided on the adjustment plate 2 35. The adjustment plate 2 35 is fixed to the drive plate 2 17 along the length direction of the adjustment groove 4 351. Thus, the front and rear positions of the rear clamp 3 are adjusted by the adjustment groove 4 351. That is, the rear clamp 3 can be adjusted and installed along the adjustment groove 4 351 in the front and rear direction to adapt to the pressing and fixing of bag openings of different sizes. This improves the applicability of pressing bag openings of different sizes. Thus, a set of front clamp 2 and rear clamp 3 can meet the processing of most sizes of bag openings, reducing the inventory cost and replacement time cost.

[0043] Furthermore, a notch for the avoidance adjustment plate 35 is provided on the outer pressure frame 1, so that the installation position of the rear clamp 3 can be adjusted back and forth through the adjustment groove 351 without disassembling the rear clamp 3, making the adjustment operation of the rear clamp 3 more convenient.

[0044] The drive plate 14 is provided with an adjustment groove 141. The front clip 2 is installed on the drive plate 14 along the length of the adjustment groove 141. The installation position of the front clip 2 can be adjusted back and forth by adjusting the adjustment groove 141.

[0045] Furthermore, a fixing plate 33 is provided on the rear clamp 3. The fixing plate 33 is fitted onto the rear clamp 3. An adjusting plate 34 for connecting the rear clamp 3 is fixed on the fixing plate 33. An adjusting groove 341 is provided on the adjusting plate 34. The rear clamp 3 is adjusted back and forth along the length direction of the adjusting groove 341 and installed on the adjusting plate 34. The installation position of the rear clamp 3 is adjusted back and forth through the adjusting groove 341.

[0046] By setting adjustment groove 2 141 and adjustment groove 341, the front clamping piece 2 and the rear clamping piece 3 can be flexibly adjusted and installed, making the adjustment, installation and maintenance of the front clamping piece 2 and the rear clamping piece 3 more convenient. Through adjustment, it is ensured 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, making the pressing and flanging operation of the clamping end 21 and the rear clamping end 31 more reliable.

[0047] 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

[0048] like Figures 7-8 As shown, in this embodiment, the double clamping mechanism for the bag opening flange of the bag opening machine does not have ear pieces 32.

[0049] 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

[0050] One end of the front clamp 2 and the rear clamp 3 are fixedly connected to the outer pressure frame 1. A first cylinder and a second cylinder are respectively provided below the front clamp 2 and the rear clamp 3 to drive them to rotate and swing upward.

[0051] Specifically, in the initial state, one end of the front clamp 2 and the rear clamp 3 are fixedly connected to the outer pressure frame 1, and the front clamping end 21 of the front clamp 2 and the rear clamping end 31 of the rear clamp 3 are spaced apart from the fixed material window 11, so that the bag opening can be turned inside the fixed material window 11.

[0052] The output end of the first cylinder abuts against the front clamping plate 2, thereby driving the front clamping plate 2 to swing upward, so that the front clamping end 21 is pressed upward against the front edge of the fixed material window 11; at the same time, the output end of the second cylinder moves synchronously with the first cylinder, that is, the output end of the second cylinder also abuts against the rear clamping plate 3, and drives the rear clamping plate 3 to swing upward, so that the rear clamping end 31 is pressed upward against the rear edge of the fixed material window 11.

[0053] Then, the first cylinder and the second cylinder simultaneously drive the front clamp 2 and the rear clamp 3 to swing upward, so as to press and fix the bag opening flange, thus ensuring the stability and reliability of subsequent bag opening processing.

[0054] 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.
