Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sewing, and in particular relates to an auxiliary folding 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] In order to enable the hemming piece of the fabric to be folded to form a hem, a hemming component is usually arranged at the bottom of the fabric, and the front end of the hemming component is used for wrapping the folded hemming piece, so that the hemming piece is constructed at the front end of the hemming component to form a hem.
[0004] However, since the folding part will need to be sewn later (sewing pocket cloth or zipper at the folding part), in order to solve the interference between the front end of the folding part and the sewing cutter head, the applicant creatively connects the driver to the folding part so that the folding part can move telescopically. The folding part moves telescopically, leaving space for sewing at the front end of the folding part, avoiding interference between the front end of the folding part and the sewing cutter head. However, when the folding part is telescopically set, new problems arise. This is mainly reflected in the fact that the folding part is prone to deviation during telescopic movement, resulting in the folding part being unable to move accurately to the position where the folding part needs to be folded, and the folding piece cannot accurately cooperate with the front end of the folding part to form a fold.
[0005] In summary, it is urgent to solve the problem of offset when the folding component moves in telescopic motion. Utility Model Content
[0006] The utility model provides an auxiliary folding mechanism, which aims to solve the problem of deviation when the folding component moves in a telescopic manner.

[0008] In this solution, the driver drives the folding component to perform telescopic movement. When the folding component is extended, the folding component can be adapted to the folded folding sheet, so that the folded folding sheet is wrapped around the front end of the folding component, and the folding sheet forms a fold. After the fold is formed, the driver drives the folding component to retract to prevent the folding component from interfering with subsequent steps. At the same time, the folding component is guided for telescopic movement by the configured guide part, solving the problem of displacement of the folding component during telescopic movement. In addition, the guide part can fix and support the folding component, making the folding component more stable.
[0009] Preferably, in order to enhance the strength of the folding component, the present solution preferably configures the folding component with a bending portion.
[0010] In this solution, the folding part is configured with a bent portion, so that the folding part can enhance the strength of the folding part compared to the straight-line folding piece part.

[0012] In this solution, the telescopic cylinder is used as the power for the telescopic movement of the folding component, and the structure is simpler.
[0013] Preferably, in order to realize the constraint and guidance of the folding component, the guiding portion is preferably a guiding groove in this solution, the folding component is embedded in the guiding groove, and the guiding groove guides the movement of the folding component.
[0014] In this solution, the folding parts are embedded in the guide groove, and the folding parts are restrained and guided by the mutual limitation of the folding parts in the limiting groove. At the same time, compared with other guiding methods, such as configuring guide rails, the guiding method implemented by the guide groove has a simpler structure, a more compact device, and a lower cost.

In other words, the guide groove is located in the inner side of the guide opening. Obviously, compared with setting the guide opening in other directions (such as the outer side of the folding component), the guide groove is located in the inner side of the guide opening, which reduces the interference with the external structure and makes the structure more compact.
[0017] Preferably, in order to cooperate with both sides of the folding component at the same time to achieve a better guiding effect, the present solution preferably provides the guiding portion on the guiding component, and the guiding component is provided with at least two guiding components, which are used to correspond to both sides of the folding component respectively, and each guiding component is constructed with a guiding portion.
[0018] In this solution, at least two guide components are provided, and at least one guide component is respectively provided on both sides of the folding component to cooperate with each other. Therefore, at least two guide components respectively limit the two sides of the folding component, and the folding component is more stable, solving the problem of left and right deviation of the folding component.
[0019] Alternatively, in order to cooperate with both sides of the folding component at the same time to achieve a better guiding effect, the guiding part in this solution is arranged on the guiding component, the guiding component is arranged as one, and guiding parts are arranged on both sides of the guiding component, and the guiding parts located on both sides of the guiding component correspond to the two sides of the folding component respectively.

The guide parts on both sides cooperate with the two sides of the folding component respectively, so as to limit the two sides of the folding component, make the folding component more stable, and solve the problem of left and right deviation of the folding component.
[0021] Preferably, in order to ensure that the guide part and the folding part are precisely matched, the present solution preferably further includes a mounting component, and the driver and the guide component are mounted on the mounting component.
[0022] In this solution, the guide component and the driver are both installed on the mounting component, so that the guide component and the folding component can be stably matched. At the same time, since the driver and the guide component are installed on the mounting component, the integration of the device is higher.
[0023] In order to adapt to openings of different sizes, the second aspect of the utility model further provides a folding device, including the above-mentioned folding mechanism and a driving mechanism, the folding mechanism is transmission-connected to the driving mechanism, and the driving mechanism is used to drive the folding mechanism to move.
[0024] In this solution, when it is necessary to adapt to openings of different sizes, the driving mechanism can drive the folding mechanism to move, so that the folding mechanism moves to a position that adapts to the opening, thereby achieving the adaptation of the folding mechanism to openings of different sizes.
[0025] Preferably, in order to simultaneously adapt to the folding parts on the symmetrical sides of the opening, the folding mechanisms in this solution are provided in at least two and are arranged relatively to each other, and the driving mechanism can drive the distance between the folding mechanisms to expand or decrease.
[0026] In this solution, the folding mechanisms at symmetrical positions can adapt to the folding pieces at different sides of the opening. At the same time, when the size of the opening changes, the driving mechanism can drive the folding mechanisms at the symmetrical sides to move closer or farther away from each other, so that they can adapt to openings of different sizes.
[0027] In order to guide the folding mechanism to perform telescopic movement, the present solution preferably further includes a guiding mechanism, wherein the guiding mechanism is connected to the folding mechanism and is used to guide the movement of the folding mechanism.

[0043] 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.
[0044] 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.
[0045] 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.
[0046] Example 1
[0047] Basically as attached Figure 1 As shown, a folding mechanism for auxiliary folding is mainly used to cooperate with the folded folding piece 8 so that the folding piece 8 forms a folded edge 9.
[0048] like Figure 2As shown, the folding mechanism in the embodiment of the present disclosure includes a folding component 1 and a driver 2, and the folding component 1 is transmission-connected to the driver 2. The driver 2 can drive the folding component 1 to perform telescopic movement. In the embodiment of the present disclosure, the driver 2 is preferably a telescopic cylinder, and the folding component 1 is fixedly connected to the telescopic end of the telescopic cylinder. During implementation, the tail end of the folding component 1 can be directly welded to the telescopic end of the telescopic cylinder, so that when the telescopic cylinder telescopes, the folding component 1 also telescopes.
[0049] Take an application scenario as an example: when the hem piece 8 needs to form a hem 9, the retractor drives the hem component 1 to extend. Then the folded hem piece 8 is wrapped around the front end of the hem component 1, so that the hem piece 8 forms a hem 9, as shown in FIG. Figure 4 After the folding edge 9 is formed, the driver 2 drives the folding edge component 1 to retract, so as to prevent the folding edge device 7 from affecting the subsequent sewing steps, thus solving the shortcomings of the prior art.
[0050] It should be noted that: in the embodiment of the present disclosure, the driver 2 is preferably a driving cylinder, but in some other embodiments, the driver 2 may also be other existing structures. For example, the driver 2 may be set as a driving motor, the output shaft of the driving motor is configured with a gear, and then a rack is configured on the folding component 1, and the rack is meshed with the driving motor to achieve telescopic movement.
[0051] The driver 2 in the embodiment of the present disclosure is mounted on a mounting component, which serves as a mounting base for the driver 2 to ensure that the driver 2 can remain stable. The mounting component is preferably a mounting plate 4, and during implementation, the driver 2 can be mounted on the mounting component by configuring fasteners.
[0052] like Figure 1 As shown, in the embodiment of the present disclosure, guide components 3 are also provided on the left and right sides of the front end of the mounting component, that is, there are two guide components 3, and each guide component 3 is provided with a guide portion 31. The guide portion 31 in the embodiment of the present disclosure is a guide groove, and the guide groove is constructed on the side of the guide component 3. The guide groove is used to adapt to the folding component 1 to guide and support the folding component 1. Figure 2 and Figure 3 As shown, the folding part 1 in the embodiment of the present disclosure is Y-shaped as a whole, so that the rear end of the folding part 1 constructs a guide opening 11. In the embodiment of the present disclosure, two guide parts 3 are located inside the guide opening 11, and the left and right inner walls of the guide opening 11 cooperate with the guide grooves constructed on the two guide parts 3 respectively.
[0053] Take an application scenario as an example: when the driver 2 drives the folding component 1 to telescopically move, the folding component 1 slides along the guide groove, making the telescopic movement of the folding component 1 more precise. At the same time, since the folding component 1 and the guide groove are in a mating state, the front end of the folding component 1 is supported by the guide component 3, and the folding component 1 is more stable, avoiding the folding component 1 from being offset due to force. In addition, since the left and right sides of the folding component 1 are restricted by the guide component 3, the folding component 1 will not deviate left and right, and the folding component 1 is more stable.
[0054] It should be noted that in the embodiment of the present disclosure, the guide portion 31 is a guide groove, and the guiding of the folding component 1 is achieved through the guide groove. However, in some other embodiments, the guide portion 31 may also be other guide portions 31 in the prior art. For example: the guide portion 31 may be a guide opening in the prior art. The guide opening is arranged through the guide component 3. At the same time, the two sides of the guide opening 11 of the guide component 3 are respectively accommodated in the guide opening. The guiding of the folding component 1 is achieved through the guide opening. Alternatively, the guide portion 31 may also be a guide rail slider structure, the slide rail is installed on the folding component 1, the slider is installed on the surface of the guide component 3, and the slide rail and the slider are installed in coordination. The telescopic guiding of the folding component 1 is achieved through the coordination of the slide rail and the slider.
[0055] It should be noted that, in the embodiment of the present disclosure, two guide components 3 are provided to realize the guidance of the left and right sides of the folding part 1. However, in some other embodiments, more than two guide components 3 may be provided, for example, 3, 4, 6, and so on. The guide components 3 are also symmetrically installed on both sides, and each guide component 3 is provided with a guide groove. The guidance of the folding part 1 can also be realized by more than two guide grooves. Of course, in some other embodiments, only one guide component 3 may be provided, and one guide component 3 is also accommodated inside the guide opening. At the same time, guide grooves are respectively constructed on the left and right sides of the guide component 3, and the guide grooves on both sides are respectively adapted to the inner walls on both sides of the guide opening, so that the guiding of the folding part 1 is realized by one guide component 3.
[0056] In order to enhance the strength of the folding part 1, the folding part 1 in the embodiment of the present disclosure is configured with a bending portion 12, which is formed by bending downward. The folding part 1 has a higher overall strength through the bending portion 12. In addition, when the folding part 1 interferes with some parts, the bending portion 12 can avoid the related parts, which is more practical.
[0057] The following is a further detailed description through a specific implementation method: When the hemming sheet 8 needs to form a hem 9, the retractor drives the hemming component 1 to extend. Then the folded hemming sheet 8 is wrapped around the front end of the hemming component 1, so that the hemming sheet 8 forms a hem 9. After the hem 9 is formed, the driver 2 drives the hemming component 1 to retract to prevent the hemming component 1 from affecting the subsequent process.
[0058] When the folding component 1 performs telescopic movement, the folding component 1 is guided by the guide groove, thereby solving the problem of the folding component 1 being offset.
[0059] Example 2
[0060] In order to adapt to openings of different sizes, the embodiments of the present disclosure include: Figure 5 As shown, a folding device is provided, comprising the folding device of embodiment 1 and a driving mechanism 5.
[0061] In the disclosed embodiment, two folding devices are provided, and the two folding devices are respectively provided on the left and right sides or the front and back sides of the opening. The folding devices located on different sides of the opening can adapt the folding pieces 8 on different sides of the opening. Therefore, when the folding pieces 8 on different sides are folded, the folding devices located on the corresponding side can realize the folding 9 of the folding pieces 8 folded on different sides.
[0062] At the same time, since the opening sizes required in different scenarios are different, based on this, in order to make the opening sizes different, the folding device can adapt to the folding pieces 8 on different sides. In the embodiment of the present disclosure, each folding device is respectively connected to a driving mechanism 5. The driving mechanism 5 is preferably a telescopic cylinder, which can be a telescopic air cylinder or a telescopic oil cylinder.
[0063] The rear end of the driving mechanism 5 in the embodiment of the present disclosure is fixedly installed, specifically, it can be installed on a frame or the like, and the front end of the driving mechanism 5 is connected to the mounting plate 4 in the folding device. When the driving mechanism 5 performs telescopic movement, the folding device also telescopes, and the position of the folding device forming the fold 9 can also change accordingly.
[0064] It should be noted that: in the embodiment of the present disclosure, the driving mechanism 5 is preferably a telescopic cylinder, but the driving mechanism 5 can also be a conventional driving device in the prior art such as a driving motor. For example, when the driving mechanism 5 is a driving motor, a gear can be configured on the output shaft of the driving motor, and a rack can be provided on the mounting plate 4 of the folding device, and the rack and the gear are meshed with each other. The driving motor drives the rack to move, and finally drives the position of the folding device to change.
[0065] like Figure 5As shown, in order to achieve the guidance of the folding device, the embodiment of the present disclosure preferably also includes a guide mechanism 6, and the guide mechanism 6 includes a guide rod and a guide block. The guide block is fixedly installed at a position such as a frame, and can be installed by configuring fasteners or welding during implementation. The guide block is internally constructed with a penetrating guide channel, and the guide rod is fixedly connected to the guide component 3 in the folding device. During implementation, it can be connected by configuring fasteners or welding. Moreover, in the embodiment of the present disclosure, the guide rod is accommodated inside the guide channel. Therefore, when the folding device telescopes, the folding device moves along the guide rod, and the folding device is guided by the guide rod and the guide block, and the movement of the folding device is more precise.
[0066] In addition, Figure 5 As shown, in the embodiment of the present disclosure, two guide rods and two guide blocks are provided, and the two guide rods and two guide blocks are symmetrically arranged on both sides of the folding device, so that both sides of the folding device are guided.

[0068] The present disclosure provides a bag opening machine. Figure 6 As shown, it includes the folding device of Example 2, the folding device 7 and the frame, and the folding device and the folding device 7 are installed on the frame, and the frame can be a bag opening machine frame in the prior art (not shown in the figure).
[0069] In the embodiment of the present disclosure, the folding device and the folding tool 7 are respectively installed in a top-to-bottom cooperation. A protrusion 71 is provided at the bottom edge of the folding tool 7. When the folding tool 7 is moved under the drive of the power module, the protrusion 71 at the edge of the folding tool 7 pushes the folding sheet 8, so that the folding sheet 8 is folded. The folded folding sheet 8 is adapted to the folding device, so that the folding sheet 8 forms a folded edge 9.
[0070] The power module in the embodiment of the present disclosure may be a power mechanism in the prior art, such as a robotic arm.
[0071] 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.
[0072] 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. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
