Description

Technical Field

[0001] The utility model belongs to the field of sewing, and in particular relates to a folding matching mechanism, a device and a bag opening machine. Background Art

[0002] The bag opening machine is a device that is often needed in the sewing field. The bag opening machine is mainly used to construct a rectangular opening at a specific position of the fabric, and then after subsequent sewing and other steps, the pocket of the garment is finally formed. In order to construct a rectangular opening at a specific position of the fabric, the bag opening machine first needs to cut at a specific position of the fabric to form a Y-shaped cutting line at both ends, such as Figure 7 As shown, the hem piece at the cutting line is then folded over to form a rectangular opening at the cutting point of the fabric, as shown in FIG. Figure 8 The rectangular opening can be sewn to form a pocket of the garment.

[0003] However, conventional bag opening machines in the prior art can usually only form openings of fixed sizes. For example, the bag opening machines disclosed in the prior art such as patents CN111575926A and CN202010348853.X cannot form openings of different sizes as needed, which is very inconvenient to use.

[0004] In order to solve the problem that conventional bag openers cannot form openings of different sizes, the applicant creatively provides a new bag opener that can form openings of different sizes to meet different usage needs. Since the bag opener can construct openings of different sizes, when it is necessary to form a folded edge sheet at the opening, the folding component used to adapt to the folded edge sheet in the conventional technology only has a retraction function (for example, the folding component disclosed in CN111575926A), and the folding component cannot be accurately moved to the position to match the folded edge sheet. Utility Model Content

[0005] The utility model provides a folding matching mechanism, a device and a bag opening machine, aiming to solve the problem that conventional folding components cannot be matched with openings of different sizes.

[0006] In order to achieve the above-mentioned purpose, the first aspect of the utility model provides a folding matching mechanism, including a folding module, the folding module includes a folding piece and a first telescope, the first telescope is connected to the folding piece, and the first telescope is used to drive the telescopic movement of the folding piece; the folding piece is used to adapt to the folded folding piece so that the folded folding piece forms a folded edge.

[0007] In this solution, the folding piece is connected to the first retractor, so the first retractor can drive the folding piece to retract and move. Therefore, when the opening size is different, the first retractor can drive the folding piece to retract and move to different positions under the opening conditions of different sizes, so that the folding piece and the hem piece are accurately matched, and the hem piece forms a hem.

[0008] Preferably, after the hemming piece is folded to form a hem, in order to solve the problem of the hemming piece rebounding, the solution further includes a fixing module, the fixing module includes a clip and a driver, the clip is located below the hem, the driver is connected to the clip in a transmission manner, and the driver is used to drive the clip to fix the hem.

[0009] In this solution, after the hemming piece forms a folded edge, the driver in the fixing module is used to drive the clamping piece to clamp and fix the folded hemming piece to prevent the hemming piece from rebounding, so that a rectangular opening is formed on the fabric.

[0010] Preferably, in order to achieve guidance during the expansion and contraction movement of the flap and solve the problem of deviation during the expansion and contraction movement of the flap, the present solution preferably provides a guide portion corresponding to the flap, the guide portion being used to guide the movement of the flap.

[0011] In this solution, a guide part is provided to cooperate with the flap. Therefore, when the flap performs telescopic movement, the flap is guided and restricted by the guide part, the flap will not deviate during the telescopic movement, and the flap movement is more accurate. The guide part of this solution can ensure that the flap moves accurately to the corresponding position, ensuring that the position of the folded edge is accurately formed.

[0012] Preferably, in order to guide the folding piece, the guiding part is preferably a guiding groove.

[0013] In this solution, the folding piece is embedded in the guide groove, and the inner wall of the guide groove and the folding piece are mutually limited, thereby achieving the guidance of the telescopic movement of the folding piece.

[0014] In order to enable both sides of the folding piece to be fixed and guided by the guide groove, in this solution, the guide parts are preferably provided in at least two portions, and the at least two guide parts are used to cooperate with the two sides of the folding piece.

[0015] In this solution, guide parts are arranged on both the left and right sides of the flap, so as to ensure that both the left and right sides of the flap are guided and restricted, and the movement of the flap is more stable.

[0016] In order to make the device more integrated and more compact, in this solution, the guide part is preferably arranged on the fixing module.

[0017] Preferably, in order to fix the fabric, the fixing module in this solution preferably includes a connecting component, the driver is a second retractor, the connecting component can be rotatably installed, the clip and the second retractor are respectively connected to the upper and lower ends of the clip, and the second retractor drives the connecting component to rotate so that the fixed end of the clip is lifted or pressed.

[0018] In this solution, the second retractor is used as a power to drive the connecting component to rotate, and the connecting component is connected to the clip. The rotating connecting component drives the clip to rotate, so that the fixed end of the clip is lifted or pressed. When the clip is lifted, the cloth is separated from the clip; when the clip is pressed, the cloth is pressed and fixed by the clip.

[0019] Preferably, in order to make the cloth more stable and avoid displacement of the cloth when the clip fixes the cloth, the present solution preferably configures the clip with fixing teeth, and the fixing teeth are used to fix the cloth.

[0020] In this solution, when the fixing teeth are in contact with the cloth, the fixing teeth can increase the friction between the clip and the cloth, so that the cloth is fixed by the clip more stably.

[0021] Preferably, in order to make the folding module and the fixing module more integrated and avoid interference between them, the present solution preferably has the folding module and the fixing module both installed on a mounting plate, and the folding module and the fixing module are located on different sides of the mounting plate, respectively.

[0022] In this solution, the folding module and the fixing module are respectively installed on different sides of the mounting component, and the folding module and the fixing module are integrated together, which has a higher degree of integration. At the same time, because the folding module and the fixing module are respectively installed on different sides of the mounting component, the folding module and the fixing module will not interfere with each other.

[0023] In order to enable the hemming pieces on the symmetrical sides of the opening to form hems, the second aspect of the utility model discloses a hemming matching device, comprising at least two of the above matching mechanisms, and the at least two matching mechanisms are arranged opposite to each other.

[0024] In this solution, by providing at least two matching mechanisms, different matching mechanisms can be adapted to the hemming pieces on different sides, so that the hemming pieces on different sides of the cloth opening can form hems.

[0025] Preferably, due to the different sizes of the openings, in order to enable the matching mechanism to adapt to the folding piece when the opening sizes are different, the present solution preferably also includes a moving mechanism, which is connected to the matching mechanism, and the moving mechanism is used to drive the distance between the matching mechanisms to decrease or increase.

[0026] In this solution, when the size of the opening changes, the moving mechanism can make the matching mechanism move symmetrically, so that the matching mechanism on the symmetrical side moves to the position of the hemming piece correspondingly, thereby realizing the hemming of the hemming pieces on different sides.

[0027] The third aspect of the utility model provides a bag opening machine, comprising the above-mentioned matching device and a folding device, wherein the folding device is used to drive the folding piece to be folded, and the matching device is used to match with the folded folding piece.

[0028] In this solution, the folding piece is folded by a folding device, and then the folded folding piece is processed by a matching device, and a folded edge is formed at the folding piece and fixed.

[0029] The beneficial effect of the utility model is that the folding piece is connected to the first retractor in the present solution, so the first retractor can drive the folding piece to perform telescopic movement. Therefore, when the opening size is different, the first retractor can drive the folding piece to telescopically move to different positions under the opening conditions of different sizes, so that the folding piece and the hem piece are accurately matched, and the hem piece forms a hem.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0040] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0041] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0042] Example 1

[0043] Basically as attached Figure 1 As shown, a folding matching mechanism is mainly used to adapt to the folded folding piece 5, so that the folded folding piece 5 forms a folded edge 6 and is finally fixed.

[0044] like Figure 1 and Figure 2 As shown, the processing mechanism in the embodiment of the present disclosure mainly includes a folding module 1, a fixing module 2 and a mounting component 3, and the mounting component 3 is a mounting plate. The folding module 1 and the fixing module 2 are respectively arranged at the bottom and the top of the mounting plate, so that the folding module 1 and the fixing module 2 are integrated together. The folding module 1 in the embodiment of the present disclosure is used to adapt to the folded folding sheet 5 so that the folding sheet 5 forms a folding 6 at the opening. The fixing module 2 is used to fix the folding sheet 5 after the folding 6 is formed to prevent the folding sheet 5 from rebounding.

[0045] like Figure 4 As shown, the hemming module 1 in the embodiment of the present disclosure includes a folding piece 11 and a first telescopic device 12, wherein the first telescopic device 12 may be a telescopic cylinder or a telescopic oil cylinder, and the first telescopic device 12 is used to provide power to the folding piece 11 so that the folding piece 11 can telescope. The tail end of the folding piece 11 is fixedly connected to the telescopic end of the first telescopic device 12, and specifically, the connection may be made by configuring a fastener or directly welding.

[0046] Take an application scenario as an example: when it is necessary to form a folded edge 6, the first retractor 12 drives the folding piece 11 to extend so that the front end of the folding piece 11 moves to the edge of the opening. The folded folding piece 5 can be wrapped around the front end of the folding piece 11, so that the folding piece 5 forms a folded edge 6 at the front end of the folding piece 11. Figure 5 At the same time, when the size of the opening is different, the first retractor 12 drives the flap 11 to extend to different positions, ensuring that the front end of the flap 11 can fit with the hem piece 5.

[0047] like Figure 4 As shown, in order to strengthen the strength of the flap 11, the flap 11 in the disclosed embodiment is configured with a bending portion, which is formed by bending downward. The flap 11 is formed by the bending portion, so that the overall strength of the flap 11 can be higher while being as thin as possible. In addition, when the flap 11 interferes with some parts, the bending portion can avoid the relevant parts.

[0048] After the folded edge sheet 5 is formed into the edge 6 by the folding sheet 11, the edge sheet 5 after the edge 6 is formed is fixed by the fixing module 2 in the embodiment of the present disclosure. Figure 3 As shown, the fixing module 2 specifically includes a clip 21, a connecting component 22, a rotating shaft 23, a rotating shaft seat 24 and a second retractor 25. The clip 21 is in a long strip shape, and the clip 21 is used to contact the folded edge sheet 5 and fix the folded edge sheet 5 to prevent the folded edge sheet 5 from rebounding. The fixing module 2 in the embodiment of the present disclosure is installed on the mounting plate. During implementation, the rotating shaft seats 24 are respectively provided on the left and right sides of the front end of the mounting plate, and the rotating shaft seats 24 are installed on the mounting plate by setting fasteners. The rotating shaft seats 24 located on the left and right sides of the front end of the mounting plate are both constructed with shaft holes that horizontally penetrate the rotating shaft seats 24. The left and right ends of the rotating shaft 23 are respectively adapted to the inside of the shaft holes of the rotating shaft seats 24 on both sides, so that the rotating shaft 23 is stably installed. In the embodiment of the present disclosure, the rotating shaft 23 can be rotatably arranged in the rotating shaft 23, or the two ends of the rotating shaft 23 can be directly fixed to the rotating shaft 23, such as welding. The middle part of the connecting component 22 is also penetrated with a shaft hole. The rotating shaft 23 passes through the connecting component 22 from the shaft hole of the connecting component 22, so that the connecting component 22 can be rotatably mounted on the rotating shaft 23, and the connecting component 22 can rotate around the rotating shaft 23. The clip 21 is fixedly connected to the bottom of the connecting component 22, and can be connected by welding or configuring fasteners. The second telescopic device 25 can be a telescopic cylinder or a telescopic oil cylinder. The second telescopic device 25 is fixedly mounted on the mounting plate, and the second telescopic device 25 is connected to the top of the connecting component 22.

[0049] Taking an application scenario as an example, when the telescopic end of the second telescopic device 25 is extended, the telescopic end of the second telescopic device 25 drives the upper end of the connecting component 22 to move forward. When the upper end of the connecting component 22 moves forward, the connecting component 22 can rotate around the rotating shaft 23, and the lower end of the connecting component 22 moves backward. When the lower end of the connecting component 22 moves backward, the clip 21 connected to the lower end of the connecting component 22 can be tilted, so that the hemming piece 5 can enter the clip 21 and be clamped, or the hemming piece 5 can be separated from the clip 21. When the telescopic end of the second telescopic device 25 is retracted, the telescopic end of the second telescopic device 25 drives the upper end of the connecting component 22 to move backward. When the upper end of the connecting component 22 moves backward, the connecting component 22 can rotate around the rotating shaft 23, and the lower end of the connecting component 22 moves forward. When the lower end of the connecting component 22 moves forward, the clip 21 connected to the lower end of the connecting component 22 can be pressed together, so that the hemming piece 5 is fixed.

[0050] like Figure 3 As shown, the second telescopic device 25 in the embodiment of the present disclosure is connected to the top of the connecting component 22. Based on this, in order to avoid the connection between the second telescopic device 25 and the connecting component 22 from getting stuck during the rotation of the connecting component 22, the connection between the second telescopic device 25 and the connecting component 22 in the embodiment of the present disclosure is a movable connection. During implementation, an annular groove can be provided at the telescopic end of the telescopic cylinder, and at the same time, an arc-shaped bayonet is provided at the upper end of the connecting component 22. The bayonet at the upper end of the connecting component 22 is inserted into the annular groove of the telescopic cylinder, and the width of the annular groove of the telescopic cylinder is greater than the width of the upper end of the connecting component 22.

[0051] Taking an application scenario as an example, when the telescopic end of the second telescopic device 25 is extended, the rear side wall of the annular groove contacts the upper end of the connecting component 22, and the second telescopic device 25 can push the upper end of the connecting component 22 to move forward; when the telescopic end of the second telescopic device 25 is retracted, the front side wall of the annular groove contacts the upper end of the connecting component 22, and the second telescopic device 25 can drive the upper end of the connecting component 22 to move backward. In the embodiment of the present disclosure, the above-mentioned setting method avoids the connection between the second telescopic device 25 and the connecting component 22 from getting stuck during the rotation of the connecting component 22, ensuring that the connecting component 22 can be driven to rotate normally.

[0052] In order to enable the clip 21 to clamp the hem piece 5 more stably, the clamping end of the clip 21 is also provided with a restraining tooth, such as Figure 3 As shown, it is ensured that the clamping end of the clip 21 can stably fix the hemming sheet 5 to prevent the hemming sheet 5 from sliding. The restraining teeth are arranged on the upper surface of the clamping end of the clip 21. The restraining teeth can provide greater friction force to prevent the hemming sheet 5 from sliding away from the clamping end of the clip 21.

[0053] In order to guide the telescopic movement of the folding piece 11 in the disclosed embodiment, the left and right sides of the folding piece 11 are fixed at the same time. In the disclosed embodiment, a guide portion is preferably configured on the side of the rotating shaft seat 24, and the guide portion is preferably a guide groove, such as Figure 3 At the same time, the folding piece 11 in the embodiment of the present disclosure is Y-shaped as a whole, as shown in FIG. Figure 4 As shown, the tail end of the flap 11 is formed into a guide opening. The guide grooves on the sides of the two rotating shaft seats 24 in the disclosed embodiment are respectively matched with the left and right side walls of the guide opening, such as Figure 1 shown.

[0054] Take an application scenario as an example: when the folding piece 11 telescopes under the action of the first telescoping device 12, the left and right sides of the folding piece 11 are respectively guided by the guide grooves on both sides, so that the movement of the folding piece 11 is more precise, ensuring that the position of the hem 6 formed by the hem 5 is more advanced. At the same time, the shaft seat 24 can support the front end of the folding piece 11 to prevent the front end of the folding piece 11 from being forced to deflect downward. In addition, since the left and right sides of the folding piece 11 are respectively guided by the guide grooves on both sides, the left and right sides of the folding piece 11 will not shake, and the hem 5 is more stable.

[0055] It should be noted that a driving method for the clip 21 is disclosed in the embodiment of the present disclosure, and the clip 21 can be driven to clamp the folding sheet 5, but there are multiple driving methods for the clip 21. For example: In some other embodiments, the clip 21 can be driven to lift and lower by a lifting cylinder, so as to fix and release the folding sheet 5. Take an application scenario as an example: when the lifting cylinder rises, the clip 21 can be driven to rise by the lifting cylinder, so that the clip 21 clamps the folding sheet 5. When the lifting cylinder retracts, the clip 21 can be driven to descend by the lifting cylinder, so that the clip 21 releases the folding sheet 5.

[0056] The following is a further detailed description through a specific implementation method: When it is necessary to form a folded edge 6, the first retractor 12 drives the folded sheet 11 to extend so that the front end of the folded sheet 11 moves to the edge of the opening. The folded folded sheet 5 can be wrapped around the front end of the folded sheet 11, so that the folded sheet 5 at the opening forms a folded edge 6. After the folded edge 6 is formed, the second retractor 25 in the fixing module 2 drives the clamping piece 21 to rotate, and the clamping piece 21 fixes the folded folded sheet 5 to prevent the folded sheet 5 from rebounding.

[0057] Example 2

[0058] The embodiment of the present disclosure provides a folding matching device, which is not shown in the figure, and includes the matching mechanism and the moving mechanism in embodiment 1, and the matching mechanisms are provided in at least two and are symmetrically arranged, for example, they can be symmetrically arranged left and right or front and back.

[0059] In the embodiment of the present disclosure, each matching mechanism is connected to a moving mechanism. When implemented, the moving mechanism can be a telescopic cylinder, the tail end of which is fixedly mounted on a frame or other position, and the front end of which is fixedly connected to a mounting plate, and can be installed by welding or configuring fasteners. When the moving mechanism is working, the moving mechanism can drive the matching mechanisms arranged on both sides to move closer or farther away.

[0060] Take an application scenario as an example: when the size of the opening changes, the moving mechanism acts as a power-driven matching mechanism to move, so that the matching mechanism can move to a position that matches the hemming piece 5, thereby satisfying the problem of matching the hemming piece 5 under different opening sizes.

[0061] It should be noted that: the embodiment of the present disclosure provides a solution in which each matching mechanism is connected to a moving mechanism for driving so that the matching mechanisms arranged relatively are brought closer or farther away. However, in some other embodiments, a moving mechanism may simultaneously drive the matching mechanisms arranged relatively closer or farther away. For example, the moving mechanisms on both sides may be driven closer to each other by a clamping cylinder, etc.

[0062] Example 3

[0063] The present disclosure provides a bag opening machine. Figure 6 As shown, it includes the matching device of Example 2, the hemming device 4 and the frame, the matching device of the hemming sheet 5 and the hemming device 4 are installed on the frame, and the frame can be the bag opening machine frame in the prior art.

[0064] In the disclosed embodiment, the matching device of the hemming sheet 5 is respectively matched and installed with the hemming device 4 at the top and bottom. Both sides of the bottom edge of the hemming device 4 are provided with raised portions 41. When the hemming device 4 is moved under the drive of the power module, the raised portions 41 on the edge of the hemming device 4 push the hemming sheet 5, so that the hemming sheet 5 is folded. The folded hemming sheet 5 is adapted to the matching device, so that the hemming sheet 5 forms a folded edge 6 and is fixed.

[0065] The power module in the embodiment of the present disclosure may be a power mechanism in the prior art, such as a robotic arm.

[0066] In order to fold the hemming pieces 5 on both sides, the power mechanism can be used to drive the hemming device 4 to move on different sides, so as to fold the hemming pieces 5 on different sides. Then the matching device on the corresponding side can fold the hemming piece 5 6 and fix it.

[0067] It should be noted that in order to make the bag opening machine more automated, the bag opening machine in the embodiment of the present disclosure may also be equipped with related devices that are matched with the bag opening machine in the prior art, such as a laser cutting device.

[0068] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
