Description

Technical Field

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

[0002] The bag opening machine is a device that is often needed in the sewing field. In the process of forming the bag opening, 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, and then fold and / or fix the folding piece at the cutting line to form a rectangular opening on the fabric, such as Figure 8 The rectangular opening can be sewn to form a pocket of the garment.

[0003] In a conventional bag opener, the bag opener can only open an opening of a fixed size, and can only perform folding and / or fixing processes on the opening of a fixed size, and has poor adaptability. In order to solve the problem that the conventional bag opener can only adapt to openings of fixed sizes, the applicant creatively proposed a new bag opening device, which includes a folding edge adapter mechanism that can adapt to openings of different sizes. The folding edge adapter mechanism can adapt to the folding edge sheet at the opening when the opening size is different, and process the folding edge sheet.

[0004] However, the applicant has found in practical use that when the hemming piece is processed by the hemming adapter mechanism, the fabric often shifts, which causes the hemming adapter mechanism to be unable to process the fabric normally, and errors are prone to occur.

[0005] In summary, there is an urgent need to solve the problem of fabric displacement when the folding adapter mechanism processes the fabric. Utility Model Content

[0006] The utility model provides a cloth bag opening device, which aims to solve the problem of cloth displacement when the folding adaptor mechanism processes the cloth.

[0007] In order to achieve the above-mentioned object, the utility model provides a cloth bag opening device, including a folding edge adapter mechanism and a cloth pressing mechanism, wherein the folding edge adapter mechanism is used to process the folding edge piece;

[0008] The cloth pressing mechanism is arranged above the folding adapter mechanism, and the cloth pressing mechanism comprises a pressing frame and a cloth pressing piece. The cloth pressing piece is movably mounted on the pressing frame, and the cloth pressing end of the pressing frame extends into the pressing frame.

[0009] In this solution, the folding adapter mechanism is adapted to the folded folded edge sheet and processed. When the folding adapter mechanism is processing the folded edge sheet, the cloth pressing mechanism fixes the cloth through the pressing frame to prevent the cloth from shifting during the processing, thus solving the problem raised in the background technology.

[0010] At the same time, since the pressing frame is provided with a movable cloth pressing piece, when the sizes of the openings are different, the cloth pressing piece can be moved so that the position of the cloth pressing piece is changed to adapt to the openings of different sizes.

[0011] Preferably, in order to release and fix the cloth, the cloth pressing mechanism in this solution preferably includes a lifting component, the lifting component is transmission-connected to the pressing frame, and the lifting component is used to drive the pressing frame to press downward or lift up.

[0012] In this solution, a lifting assembly is provided to drive the lifting movement of the pressing frame. When the pressing frame is pressed downward, the fabric is fixed by the pressing frame, and the hemming adapter mechanism can accurately process the hemming piece; when the pressing frame is lifted upward, the fabric is released, and the processed fabric can be taken out normally.

[0013] Preferably, in order to drive the pressure frame to move up and down, the lifting component preferably includes a lifting cylinder.

[0014] This solution configures a lifting cylinder as a power source, and when the lifting cylinder performs a lifting motion, it drives the pressure frame to perform a lifting motion.

[0015] In order to solve the problems of misalignment and shaking of the press frame during the lifting movement, in this solution, the lifting assembly preferably includes a slide rail slider unit, and the slide rail slider unit is used to guide the lifting movement of the press frame.

[0016] This solution guides the lifting and lowering movement of the press frame by configuring a slide rail slider unit, thereby ensuring the accuracy and stability of the press frame during the lifting and lowering movement, and solving problems such as misalignment and shaking of the press frame during the lifting and lowering movement.

[0017] Preferably, in order to fix the cloth more stably, the cloth pressing end of the cloth pressing piece is preferably configured with a restraining hole. In this solution, by configuring the restraining hole at the cloth pressing end, the restraining hole can increase the friction with the cloth, ensuring that the cloth pressing end can fix the cloth more stably.

[0018] In order to ensure that the edges of the cloth pressing ends of the cloth pressing piece can all be fitted with the restraining portion, a plurality of restraining holes are provided and arranged in a straight line along the edges of the cloth pressing ends of the cloth pressing piece.

[0019] Preferably, in order to realize the folding of the folded hem piece into a folded hem, the folding adapter mechanism in this solution preferably comprises a folding module, and the folding module is used to form the folded hem piece into a folded hem.

[0020] In this solution, when the hemming piece is folded, the hemming module can cooperate with the folded hemming piece, so that a hem is formed at the hemming piece, and the opening is more beautiful.

[0021] Preferably, in order to fix the folded edge piece and prevent the edge piece from rebounding, the folding adapter mechanism preferably includes a fixing module in this solution, and the fixing module is used to fix the folded edge piece.

[0022] In this solution, when the folded edge piece is folded, the fixing module can press the folded edge piece so that the folded edge piece remains in the folded state, thereby preventing the folded edge piece from rebounding.

[0023] Preferably, in order to realize the folding of the folding piece, the folding module in this solution preferably includes a folding component and a first telescope, wherein the first telescope is connected to the folding component and can drive the folding component to perform telescopic movement.

[0024] In this solution, when the hem piece is folded, the hem component extends under the action of the first retractor, so that the hem piece is wrapped around the front end of the hem component, and the hem piece forms a hem. After the hem is formed, the hem component retracts, and the hem is vacant, which is convenient for subsequent other steps.

[0025] Preferably, in order to fix the folded edge piece, the fixing module preferably includes a fixing component, a transmission component and a second telescope. The transmission component can be rotatably installed, and the fixing component and the second telescope are respectively connected to the upper and lower ends of the transmission component. The second telescope drives the transmission component to rotate, so that the fixing component presses or releases the edge piece upward.

[0026] In this solution, when the hem piece is folded, the second retractor drives the transmission member to rotate. The transmission member rotates to drive the fixing member to press upward, and the hem piece is fixed, solving the problem of the hem piece rebounding. In addition, the hem piece remains in a stable state, which is convenient for subsequent processing of the hem piece.

[0027] Preferably, due to the different sizes of the openings, in order to enable the folding adapter mechanism to adapt to the folding piece when the opening sizes are different, the present solution preferably comprises the folding adapter mechanism further comprising a moving module, and the moving module is used to change the working position of the folding adapter mechanism.

[0028] In this solution, when the size of the opening changes, the moving module can move the folding adapter mechanism to a position that matches the folding piece, so that the folding adapter mechanism can match the folding piece when the opening size is different.

[0029] The beneficial effect of the utility model is that: in the present solution, the folding adapter mechanism is adapted to and processed with the folded folding piece. When the folding adapter mechanism is processing the folding piece, the cloth pressing mechanism fixes the cloth through the pressing frame to prevent the cloth from shifting during the processing, thus solving the problem raised in the background technology.

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.

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 cloth bag opening device includes a cloth pressing mechanism 1 and a folding adapter mechanism 2 arranged above and below, so that the cloth is kept in a stable state, which facilitates the folding adapter mechanism 2 to fold the folding piece 3 4.

[0044] like Figure 1 As shown, the cloth pressing mechanism 1 in the embodiment of the present disclosure includes a pressing frame 11, a cloth pressing plate 12 and a lifting assembly. The pressing frame 11 is annular. One side of the pressing frame 11 is connected to the lifting assembly. During implementation, the pressing frame 11 can be connected to the lifting assembly by configuring fasteners. The lifting assembly is used to drive the pressing frame 11 to move up and down, so that the pressing frame 11 and the cloth pressing plate 12 release or fix the cloth. Figure 2 As shown, the cloth pressing piece 12 in the embodiment of the present disclosure is in the shape of a sheet, and is installed on the top of the press frame 11. The cloth pressing piece 12 arranged on the top of the press frame 11 is bent toward the inside of the press frame 11, so that the cloth pressing end of the cloth pressing piece 12 can extend into the inside of the press frame 11. When the press frame 11 and the cloth pressing piece 12 need to fix the cloth, the press frame 11 and the cloth pressing piece 12 move downward to the opening position, and the opening is located in the middle of the press frame 11. The cloth pressing piece 12 located in the middle of the press frame 11 can be adapted to the edge of the opening, so that the cloth at the opening can be fixed. In addition, the cloth pressing end of the cloth pressing piece 12 extending to the middle of the press frame 11 is preferably located at the same horizontal plane as the bottom of the press frame 11, and the cloth pressing piece 12 and the press frame 11 can fix the cloth together.

[0045] It should be noted that, in the embodiment of the present disclosure, the pressing frame 11 is an annular pressing frame 11 , but in some other embodiments, the pressing frame 11 may also be in other shapes, such as a U-shape.

[0046] Take an application scenario as an example: when the cloth needs to be fixed, the lifting assembly drives the pressing frame 11 and the cloth pressing piece 12 to move downward, so that the pressing frame 11 and the cloth pressing piece 12 press the cloth. When the cloth needs to be loosened, the lifting assembly drives the pressing frame 11 and the cloth pressing piece 12 to rise, so that the pressing frame 11 and the cloth pressing piece 12 press and loosen the cloth.

[0047] like Figure 2As shown, in the disclosed embodiment, four cloth pressing pieces 12 are provided, and are respectively provided on the front and rear sides and the left and right sides of the pressing frame 11, so that the pressing frame 11 can be adapted to the front, rear, left and right sides of the opening, ensuring that the cloth on different sides of the opening can remain stable. In the disclosed embodiment, a guide groove is constructed on the cloth pressing piece 12, and the guide groove is in the shape of an elongated strip, which is located at the fixed end of the cloth pressing piece 12. At the same time, a fixing bolt is also configured on the top of the pressing frame 11, and when the cloth pressing piece 12 is installed on the pressing frame 11, the fixing bolt is accommodated in the guide groove. The fixing bolt is tightened to fix the cloth pressing piece 12; the fixing bolt is unscrewed to loosen the cloth pressing piece 12.

[0048] Take an application scenario as an example: when the size of the opening is different, the user can manually loosen the fixing bolt, and then manually drive the cloth pressing piece 12 to move along the guide groove, so that the cloth pressing end of the cloth pressing piece 12 moves to a position that matches the edge of the opening. When the cloth pressing piece 12 reaches a position that matches the edge of the opening along the guide groove, the user manually turns the fixing bolt so that the cloth pressing piece 12 cannot move further.

[0049] like Figure 2 As shown, in the disclosed embodiment, each cloth pressing piece 12 is provided with at least two mutually parallel guide grooves, and each guide groove is respectively installed with a fixing bolt. Therefore, by at least two mutually parallel guide grooves and fixing bolts, the cloth pressing piece 12 can be installed more stably.

[0050] like Figure 2 As shown, in order to enable the cloth pressing end of the cloth pressing piece 12 to fix the cloth more stably and prevent the cloth and the cloth pressing piece 12 from sliding. In the disclosed embodiment, the cloth pressing end of the cloth pressing piece 12 is preferably provided with a restraining portion, and the restraining portion is preferably a restraining hole. In the disclosed embodiment, the restraining hole can increase the friction between the cloth pressing end of the cloth pressing piece 12 and the cloth, and prevent the cloth pressing piece 12 from sliding. At the same time, there are a plurality of restraining holes in the disclosed embodiment, and they are arranged in a straight line. Therefore, the cloth pressing end of the cloth pressing piece 12 can fix the cloth more stably.

[0051] It should be noted that: the constraint part in the embodiment of the present disclosure is preferably a constraint hole, but in some other embodiments, the constraint part can also be other constraint parts in the prior art. For example: the constraint part can also be a constraint tooth, which contacts the cloth and can more stably restrict the cloth.

[0052] like Figure 1As shown, the lifting assembly for driving the pressing frame 11 and the cloth pressing plate 12 to move up and down in the disclosed embodiment includes a lifting cylinder 13 and a transmission member 14. The lifting cylinder 13 is preferably arranged vertically. The lifting cylinder 13 is installed on a frame. The transmission member 14 is in the shape of a sheet, one end of the transmission member 14 is connected to the pressing frame 11 by configuring a fastener, and the other end of the transmission member 14 is connected to the telescopic end of the lifting cylinder 13 by a fastener.

[0053] Take an application scenario as an example: when the lifting cylinder 13 performs telescopic movement, the transmission member 14 can drive the pressing frame 11 and the cloth pressing piece 12 to move up and down. When the pressing frame 11 and the cloth pressing piece 12 are raised, the pressing frame 11 and the cloth pressing piece 12 release the cloth; when the pressing frame 11 and the cloth pressing piece 12 are lowered, the pressing frame 11 and the cloth pressing piece 12 release the cloth.

[0054] In order to make the movement of the transmission member 14 more stable, the embodiment of the present disclosure preferably has two lifting cylinders 13, which are respectively connected to the left and right sides of the transmission member 14. The lifting cylinders 13 on both sides simultaneously drive the transmission member 14 to perform telescopic movement, and the movement of the transmission member 14 is more stable.

[0055] In addition, in the embodiment of the present disclosure, a slide rail slider unit 15 is further provided on the back of the transmission member 14. The slide rail slider unit 15 includes a slide rail and a slider, and the slide rail is specifically fixedly provided and can be installed on the frame by configuring fasteners or the like. The slider is installed on the slide rail, and the slider is fixedly connected to the back of the transmission member 14, and can be connected by welding during implementation. In the embodiment of the present disclosure, the transmission member 14 is guided by the slide rail slider unit 15, so that the transmission member 14 is more stable and precise when moving up and down. In addition, in the embodiment of the present disclosure, slide rail slider units 15 are provided on both the left and right sides of the back of the transmission member 14, and both sides of the back of the transmission member 14 are supported and guided by the slide rail slider units 15 on the left and right sides.

[0056] like Figure 1 As shown, in order to achieve the compression of the cloth, the pressing frame 11 in the disclosed embodiment is also provided with a corresponding supporting component below the pressing frame 11, and the supporting component is used to support the bottom of the cloth. In the disclosed embodiment, the preferred supporting component is a support plate 16. The support plate 16 is provided in two pieces, which are respectively provided on the front and rear sides. The cloth can be placed on the support plate 16, and then when the pressing frame 11 is pressed down, the cloth is compressed and fixed. Of course, in order to prevent the support plate 16 from affecting the operation of the folding adapter mechanism 2, a gap is left between the two support plates 16 for the folding adapter mechanism 2 to contact the bottom of the cloth.

[0057] It should be noted that: in addition to configuring the support plate 16 to support the bottom of the cloth, other implementation methods can also be used in some other embodiments to support the cloth. For example: an open groove is constructed on the workbench, the cloth is located on the surface of the workbench, and the workbench supports the cloth. At the same time, the hem adapter mechanism 2 processes the cloth hem piece 3 at the working groove.

[0058] like Figure 6 and Figure 7 As shown, the folding adaptation mechanism 2 in the embodiment of the present disclosure includes a fixing module 21 and a folding module 22. In the embodiment of the present disclosure, the folding module 22 is used to adapt to the folded folding piece 3 so that the folding piece 3 forms a folded edge 4. After the folding piece 3 is folded and forms the folding piece 3, the fixing module 21 fixes the folding piece 3 to prevent the folding piece 3 from rebounding, and the folding piece 3 remains in a stable state. The folding module 22 and the fixing module 21 in the embodiment of the present disclosure are both installed on the mounting plate 23, and are respectively located at the bottom and top of the mounting plate 23, so that the folding module 22 and the fixing module 21 are integrated together.

[0059] like Figure 5 As shown, the folding module 22 in the embodiment of the present disclosure includes a folding component and a first telescoping device 214, and the folding component is preferably a folding piece 221. The first telescoping device 214 can be a telescopic cylinder or a telescopic oil cylinder, and the first telescoping device 214 is used to provide power for the folding piece 221. The tail end of the folding piece 221 is fixedly connected to the telescopic end of the first telescoping device 214, and can be connected by configuring fasteners or directly welding.

[0060] Take an application scenario as an example: when a folded edge needs to be formed, the first retractor 214 drives the folding piece 221 to extend, so that the front end of the folding piece 221 moves to the edge of the opening. The folded folding piece 3 can be wrapped around the front end of the folding piece 221, so that the folding piece 3 at the opening forms a folded edge 4. After the folding piece 3 forms the folded edge 4, the first retractor 214 drives the folding piece 221 to withdraw, so as to prevent the folding piece 221 from affecting the subsequent process.

[0061] In order to strengthen the strength of the flap 221, the flap 221 in the disclosed embodiment is configured with a bending portion, which is formed by bending downward. The flap 221 has a higher overall strength through the bending portion. In addition, when the flap 221 interferes with some parts, the bending portion can avoid the relevant parts.

[0062] like Figure 3 and Figure 4As shown, the fixing module 21 specifically includes a fixing component 211, a connecting component 212, a rotating shaft, a rotating shaft seat 213 and a second retractor. The fixing component 211 is in the shape of an elongated strip and a sheet. The fixing component 211 is used to contact the folded cloth and fix and clamp the cloth to prevent the cloth from rebounding. The mounting plate 23 is rectangular. The left and right sides of the front end of the mounting plate 23 are respectively provided with rotating shaft seats 213, and the rotating shaft seats 213 are mounted on the mounting plate 23 by setting fasteners. The rotating shaft seats 213 located on the left and right sides of the front end of the mounting plate 23 are both constructed with shaft holes that horizontally penetrate the rotating shaft seats 213. The left and right ends of the rotating shaft are respectively adapted to the inside of the shaft holes of the rotating shaft seats 213 on both sides, so that the rotating shaft remains stable. In the embodiment of the present disclosure, the rotating shaft can be rotatably arranged inside the rotating shaft, or the two ends of the rotating shaft can be directly fixed to the rotating shaft, for example, by welding. The middle of the connecting component 212 is also provided with an axial hole, and the rotating shaft passes through the connecting component 212 from the axial hole of the connecting component 212, so that the connecting component 212 can be rotatably mounted on the rotating shaft, and the connecting component 212 can rotate around the rotating shaft. The fixing component 211 is fixedly connected to the bottom of the connecting component 212, specifically, it can be connected by welding or configuring fasteners, and the second telescopic device 222 can be a telescopic cylinder or a telescopic oil cylinder. The second telescopic device is installed on the mounting plate 23, and the second telescopic device 222 is connected to the top of the connecting component 212.

[0063] Taking an application scenario as an example, when the telescopic end of the second telescopic device 222 is extended, the telescopic end of the second telescopic device drives the upper end of the connecting component 212 to move forward. When the upper end of the connecting component 212 moves forward, the connecting component 212 can rotate around the rotating shaft, and the lower end of the connecting component 212 moves backward. When the lower end of the connecting component 212 moves backward, the fixed component 211 connected to the lower end of the connecting component 212 can be tilted, so that the hemming piece 3 can enter the fixed component 211 and be clamped, or the hemming piece 3 is separated from the fixed component 211. When the telescopic end of the second telescopic device 222 is retracted, the telescopic end of the second telescopic device 222 drives the upper end of the connecting component 212 to move backward. When the upper end of the connecting component 212 moves backward, the connecting component 212 can rotate around the rotating shaft, and the lower end of the connecting component 212 moves forward. When the lower end of the connecting component 212 moves forward, the fixing component 211 connected to the lower end of the connecting component 212 can be pressed together, so that the hemming piece 3 is fixed.

[0064] In order to enable the fixing member 211 to clamp the hemming piece 3 more stably, Figure 4 As shown, the clamping end of the fixing member 211 is also provided with a restraining tooth, so as to ensure that the clamping end of the fixing member 211 can stably fix the hemming piece 3 and prevent the hemming piece 3 from sliding. The restraining tooth is provided on the upper surface of the clamping end of the fixing member 211. The restraining tooth can provide greater friction force, and prevent the hemming piece 3 from sliding away from the clamping end of the fixing member 211.

[0065] In order to guide the telescopic movement of the folding piece 221 in the disclosed embodiment, the left and right sides of the folding piece 221 are fixed at the same time. In the disclosed embodiment, a restraining part is preferably configured on the side of the rotating shaft seat 213, and the restraining part is preferably a guide groove, such as Figure 6 At the same time, the folding piece 221 in the disclosed embodiment is Y-shaped as a whole, so that a guide opening is constructed at the tail end of the folding piece 221. The guide grooves on the sides of the two rotating shaft seats 213 in the disclosed embodiment are respectively matched with the left and right side walls of the guide opening.

[0066] Take an application scenario as an example: when the folding piece 221 telescopes under the action of the second telescoping device 222, the left and right sides of the folding piece 221 are respectively guided by the guide grooves on both sides, so that the movement of the folding piece 221 is more precise and the folding piece 221 is prevented from being offset. At the same time, the rotating shaft seat 213 can support the front end of the folding piece 221 to prevent the front end of the folding piece 221 from being offset downward. In addition, since the left and right sides of the folding piece 221 are respectively guided by the guide grooves on both sides, the left and right sides of the folding piece 221 will not shake.

[0067] It should be noted that: the folding adapter mechanism 2 in the embodiment of the present disclosure is configured with both the folding module 22 and the fixing module 21, but in some embodiments, the folding adapter mechanism 2 may also be configured with only one of the folding module 22 and the fixing module 21. For example: in some embodiments, the folding sheet 3 is manually folded and formed, and then the folding sheet 3 is fixed by the fixing module 21. In this case, the folding module 22 may not be configured.

[0068] like Figure 7 As shown, in the embodiment of the present disclosure, the preferred folding adaptor mechanism 2 further includes a moving module 23, and the moving module 23 is fixedly connected to the mounting plate 23. The moving module 23 can be a telescopic cylinder, the tail end of which is fixedly mounted on a frame or the like, and the front end of which is fixedly connected to the mounting plate 23, and can be installed by welding or configuring fasteners during implementation.

[0069] Take an application scenario as an example: when the size of the opening changes, the moving module 23 acts as a power to drive the folding module 22 and / or the fixing module 21 to move, so that the folding module 22 and / or the fixing module 21 can move to a position that matches the folding piece 3, thereby meeting the problem of matching the folding piece 3 under different openings.

[0070] It should be noted that: the embodiment of the present disclosure provides a structure of the moving module 23, but there are many related structures for driving movement in the prior art, so in some other embodiments, the moving module 23 may also be other structures.

[0071] The following is a further detailed description through a specific embodiment: In the embodiment of the present disclosure, before the hemming piece 3 needs to be processed, the pressing frame 11 in the cloth pressing mechanism 1 presses the cloth to keep the cloth stable. Then the hemming adapter mechanism 2 can process the hemming piece 3 so that the hemming piece 3 forms a hem 4 and is fixed.

[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.
