Description

Technical Field

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

[0002] When the bag opening machine forms the bag opening, it first needs to cut at a specific position of the fabric to form a Y-shaped cutting line at both ends, and then fold the folded edge at the cutting line to form a rectangular opening. The rectangular opening is then sewn and other steps are performed to form the pocket opening of the garment.

[0003] In the above process, after the folded edge is folded, in order to avoid the rebound of the folded edge, it is undoubtedly necessary to fix the folded edge. The device commonly used in the bag opening machine to clamp the folded edge is the cloth clamping mechanism. For example: The utility model patent of the prior art 202120799445.6 discloses a cloth clamping mechanism that can clamp the folded edge. The cloth clamping mechanism mainly includes a clip and a micro cylinder, one end of the clip is rigidly fixed, the other end of the clip is movable, and the micro cylinder is arranged in the middle of the clip. When the micro cylinder is lifted up, the movable end of the clip can be tilted up by the force, so that the folded edge can be clamped and fixed, avoiding the rebound of the folded edge.

[0004] However, there are some shortcomings in the existing cloth clamping mechanism. The main shortcomings are that the existing cloth clamping mechanism realizes the clamping of the folded edge by lifting and deforming the clamping piece. That is to say, each time the clamping is performed, the middle part of the clamping piece will be lifted up by force. Obviously, after a period of use, the clamping plate will be permanently deformed, which will eventually cause the clamping piece to fail to rebound normally or the rebound force is insufficient, and finally the cloth cannot be clamped normally.

[0005] In summary, the cloth clamping mechanism in the prior art clamps the folded edge by driving the clamping piece to deform, but there is a problem that the clamping piece cannot clamp the folded edge after deformation. Utility Model Content

[0006] The utility model provides a bag opening machine, which aims to solve the problem that a conventional cloth clamping mechanism clamps a folded edge by driving a clamping piece to deform, which causes the clamping piece to deform and fail to clamp the folded edge.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a bag opening machine, including a cloth clamping device and a folding device, wherein the folding device is used to fold the folded edge, and the cloth clamping device is used to clamp the folded edge;

[0008] The cloth clamping device includes a cloth clamping mechanism, which includes a clamping component and a power module. The clamping component is installed at the transmission end of the power module, and the power module is used to drive the clamping component to move, so that the clamping end of the clamping component fixes the cloth or releases the cloth.

[0009] In this solution, a folding device is provided to fold the folded edge, and then the folded edge is clamped and fixed by a cloth clamping device, thereby avoiding the folded edge from rebounding.

[0010] In this solution, the clamping component is driven to move by a power module. When the clamping component moves, the clamping end of the clamping component can press the folded edge so that the folded edge is fixed; when the clamping component moves, the clamping end of the clamping component can also be lifted to release the folded edge so that the folded edge is released.

[0011] The present solution uses a power module to drive the clamping component to move to achieve the fixing or releasing of the folded edge. Compared with the prior art in which the folded edge is fixed by the rebound force after the clamping component is deformed, the clamping component will not be deformed due to multiple forces and rebounds, thus solving the problem in the prior art that the clamping piece cannot fix the folded edge due to deformation.

[0012] Preferably, in order to drive the clamping component to move, the clamping component can be rotatably mounted on the frame, and the power module drives the clamping component to rotate, so that the clamping end of the clamping component fixes the cloth or releases the cloth.

[0013] In this solution, the power module is used to drive the clamping component to rotate, so that the clamping end of the clamping component fixes the cloth or releases the cloth. Compared with other movement methods, such as directly driving the clamping end of the clamping component to move up and down by the cylinder, this solution drives the clamping component to move, which requires less space in the vertical direction and is more convenient for use in locations with limited vertical space.

[0014] Preferably, in order to realize the rotation of the clamping component, the power module of this scheme preferably includes a transmission component and a driver, the transmission component can be rotatably installed, the transmission component is connected to the clamping component, the driver is connected to the transmission component in transmission connection, and the driver is used to drive the transmission component to rotate, so that the clamping end of the clamping component is tilted or pressed.

[0015] In this solution, the driver drives the transmission component to rotate, and the transmission component is then connected to the clamping component. Therefore, when the transmission component rotates, the clamping end of the clamping component can be directly driven to lift or press.

[0016] Preferably, in order to drive the transmission component to rotate, the present solution preferably configures the driver to be a telescope, wherein the telescope and the clamping component are respectively connected to the upper and lower ends of the transmission component, and the telescope moves in a telescopic manner to drive the transmission component to rotate.

[0017] In this solution, one end of the transmission component is driven to rotate by the telescopic device, and the clamping component installed at the other end of the transmission component can be driven to rotate by the transmission component. When the clamping component rotates, the clamping end of the clamping component is tilted or pressed.

[0018] In order to achieve rotatable installation of the transmission component, in this solution, the power module preferably includes a rotating shaft, and the transmission component is rotatably installed on the rotating shaft.

[0019] In this solution, the transmission component is installed on the rotating shaft, and the transmission component can rotate around the rotating shaft.

[0020] Preferably, in order to avoid jamming of the connection between the transmission component and the retractor when the retractor drives the transmission component to rotate, the present solution preferably provides that the retractor and the transmission component are movably connected.

[0021] In this solution, the telescopic device and the transmission component are movably connected, so that the movement of the telescopic device can drive the transmission component to rotate. At the same time, when the telescopic device drives the transmission component to rotate, the telescopic device and the transmission component are movably connected, so there will be no jamming between the telescopic device and the transmission component.

[0022] Preferably, in order to clamp the folded edge, the clamping component is preferably a clip.

[0023] In order to achieve more stable clamping of the folded edge, the clamping component is preferably provided with a restraining portion on the surface of the clamping component in this solution, and the restraining portion is used to limit the sliding of the folded edge.

[0024] In this solution, the sliding of the folded edge is limited by the constraint part, so that the folded edge is prevented from being separated from the clamping component, and the clamping component clamps the folded edge more stably.

[0025] Preferably, in order to limit the sliding of the folded edge, the constraint part is preferably a constraint tooth.

[0026] Preferably, in order to clamp the folded edges on different sides of the opening, the present solution preferably provides at least two cloth clamping mechanisms, each of which is used to clamp the folded edges on different sides.

[0027] In this solution, the cloth clamping mechanisms are arranged on different sides, and the cloth clamping mechanisms on different sides can clamp the folded edges on different sides of the opening to avoid the folded edges from rebounding on different sides.

[0028] Preferably, when the size of the opening changes, the position of the folding edge to be clamped is also different. Therefore, in order to enable the cloth clamping mechanism to adapt to openings of different sizes, the present solution preferably further includes a driving mechanism, which is connected to the cloth clamping mechanism and is used to drive the cloth clamping mechanism to move.

[0029] In this solution, the position of the cloth clamping mechanism is changed by a configured driving mechanism, so that the cloth clamping mechanism can be adapted to openings of different sizes.

[0030] The beneficial effect of the present utility model is that the solution adopts a method of fixing or releasing the folded edge by driving the clamping component to move through a power module. Compared with the prior art in which the folded edge is fixed by relying on the rebound force after the clamping component is deformed, the clamping component will not be deformed due to multiple forces and rebounds, thus solving the problem in the prior art that the clamping piece cannot clamp the folded edge due to deformation.

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. Example 1

[0042] Basically as attached Figure 1 As shown, a cloth clamping mechanism is mainly used to fix the folded edge 5 after it is folded to prevent the folded edge 5 from rebounding.

[0043] like Figure 1 As shown, the cloth clamping mechanism in the embodiment of the present disclosure specifically includes a clamping component 1 and a power module 2, and the supporting component is a clip, which is in the shape of a long strip. The clip is used to contact the folded edge 5 after folding, and fix and clamp the folded edge 5 to prevent the folded edge 5 from rebounding. The power module 2 includes a transmission component 21, a mounting component 25, a rotating shaft 23, a rotating shaft seat 24 and a driver 22. The mounting component 25 is a mounting plate, and the mounting plate is rectangular. The left and right sides of the front end of the mounting plate are respectively provided with rotating shaft seats 24, and the rotating shaft seats 24 are mounted on the mounting plate by setting fasteners. The mounting plate and the rotating shaft seats 24 installed on the left and right sides of the front end of the mounting plate can be collectively referred to as a frame. 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 remains stable. In the embodiment of the present disclosure, the rotating shaft 23 can be rotatably arranged inside the rotating shaft 23, or the two ends of the rotating shaft 23 can be directly fixed to the rotating shaft 23, for example, by welding. The transmission component 21 is also provided with an axial hole through the middle part, and the rotating shaft 23 passes through the transmission component 21 through the axial hole of the transmission component 21, so that the transmission component 21 can be rotatably installed on the rotating shaft 23, and the transmission component 21 can rotate around the rotating shaft 23.

[0044] like Figure 3As shown, the clamping component 1 is fixedly connected to the bottom of the transmission component 21, which can be connected by welding or configuring fasteners, and the driver 22 is a telescopic device, which can be a telescopic cylinder or a telescopic oil cylinder, etc. The telescopic device is installed on the mounting plate and connected to the top of the transmission component 21.

[0045] Taking an application scenario as an example, when the telescopic end of the telescope is extended, the telescopic end of the telescope drives the upper end of the transmission component 21 to move forward. When the upper end of the transmission component 21 moves forward, the transmission component 21 can rotate around the rotating shaft 23, and the lower end of the transmission component 21 moves backward. When the lower end of the transmission component 21 moves backward, the clip connected to the lower end of the transmission component 21 can be tilted, so that the folded edge 5 can enter the clip and be clamped, or the folded edge 5 is separated from the clip, such as Figure 4 As shown. When the telescopic end of the telescope retracts, the telescopic end of the telescope drives the upper end of the transmission component 21 to move backward. When the upper end of the transmission component 21 moves backward, the transmission component 21 can rotate around the rotating shaft 23, and the lower end of the transmission component 21 moves forward. When the lower end of the transmission component 21 moves forward, the clip connected to the lower end of the transmission component 21 can be pressed together, so that the folded edge 5 is fixed, as shown in FIG. Figure 5 shown.

[0046] It can be known from the above working process that in the embodiment of the present disclosure, the power module 2 is used to drive the clamping component 1 to move. When the clamping component 1 moves, the clamping end of the clamping component 1 can be lifted or pressed. In this process, the movement of the clamping component 1 is powered by the power module 2. Based on this, compared with the cloth clamping method in the prior art, the cloth clamping method in the embodiment of the present disclosure does not cause the clamping component 1 to be subjected to force and rebound multiple times, thereby avoiding deformation of the clamping component 1 due to multiple forces and rebounds, and ensuring that even after long-term use, the clamping component 1 will not be unable to stably clamp the folded edge 5 due to deformation of the clamping component 1.

[0047] It should be noted that: the embodiment of the present disclosure adopts a driving method of the telescopic device driving the transmission component 21 to rotate, but there are many rotation driving methods in the prior art, so in some other embodiments, the rotation driving method in the prior art can also be adopted. For example: the rotating shaft 23 of the transmission component 21 is set to be rotatable, and the rotating shaft 23 is directly fixedly connected to the transmission component 21, such as welding, and then the driving motor is used as the power to drive the rotating shaft 23 to rotate. When the driving motor drives the rotating shaft 23 to rotate, the rotation can drive the transmission component 21 to rotate.

[0048] The telescopic device in the embodiment of the present disclosure is connected to the top of the transmission component 21. Based on this, in order to avoid the connection between the telescopic device and the transmission component 21 from getting stuck during the rotation of the transmission component 21, the connection between the telescopic device and the transmission component 21 in the embodiment of the present disclosure is a movable connection. During implementation, an annular groove 221 can be provided at the telescopic end of the telescopic cylinder, and at the same time, an arc-shaped bayonet 211 is provided at the upper end of the transmission component 21. The bayonet 211 at the upper end of the transmission component 21 is inserted into the annular groove 221 of the telescopic cylinder, and the width of the annular groove 221 of the telescopic cylinder is greater than the width of the upper end of the transmission component 21. Figure 2 shown.

[0049] Taking an application scenario as an example, when the telescopic end of the telescope is extended, the rear side wall of the annular groove 221 contacts the upper end of the transmission component 21, and the telescope can push the upper end of the transmission component 21 to move forward; when the telescopic end of the telescope is retracted, the front side wall of the annular groove 221 contacts the upper end of the transmission component 21, and the telescope can drive the upper end of the transmission component 21 to move backward. Through the above-mentioned setting method, the connection between the telescope and the transmission component 21 is prevented from getting stuck during the rotation of the transmission component 21, ensuring that the transmission component 21 can be driven to rotate normally.

[0050] It should be noted that: in the embodiment of the present disclosure, the bayonet 211 and the annular groove 221 are configured to ensure the active connection between the telescope and the transmission component 21, but there are many ways to avoid jamming through active connection in the prior art, so in some other implementations, other active connection methods in the prior art can be used to avoid jamming. For example: a rotating shaft hole can be set at the telescopic end of the telescope, and a corresponding rotating shaft hole is also set at the upper end of the transmission component 21. A rotating shaft is configured between the rotating shaft holes of the telescope and the transmission component 21. When the telescopic end of the telescope drives the transmission component 21 to move forward or backward, the connection between the telescope and the transmission component 21 can rotate, thereby avoiding jamming of the connection between the telescope and the transmission component 21 during the rotation of the transmission component 21.

[0051] like Figure 3 As shown, in order to enable the clip to clamp the hem 5 more stably, a constraint portion 11 is further provided at the clamping end of the clip, thereby ensuring that the clamping end of the clip can stably fix the hem 5 and prevent the hem 5 from sliding. The constraint portion 11 is preferably a constraint tooth, which is provided on the upper surface of the clamping end of the clip. The constraint tooth can provide greater friction force to prevent the hem 5 from sliding away from the clamping end of the clip.

[0052] It should be noted that: in the embodiment of the present disclosure, a constraint tooth is configured as the constraint portion 11, but in some other embodiments, the constraint portion 11 can also be set as a constraint hole, etc. The edge of the constraint hole can also increase the friction between the folded edge 5 and the clip to prevent the folded edge 5 from sliding.

[0053] The following is a further detailed description through a specific implementation method: When the hem 5 needs to be clamped, the telescopic cylinder retracts, and the telescopic end of the telescopic cylinder pushes the upper end of the transmission component 21 to rotate backward. When the upper end of the transmission component 21 rotates backward, the lower end of the transmission component 21 rotates forward, and the lower end of the transmission component 21 can drive the clamping end of the clip to press together, so as to clamp the hem 5. When the hem 5 needs to be released, or the hem 5 needs to be embedded in the clamping position of the clip, the telescopic cylinder extends, and the telescopic end of the telescopic cylinder pushes the upper end of the transmission component 21 to rotate forward. When the upper end of the transmission component 21 rotates forward, the lower end of the transmission component 21 rotates backward, and the lower end of the transmission component 21 can drive the clamping end of the clip to tilt up. Example 2

[0054] A cloth clamping device is provided in an embodiment of the present disclosure, comprising at least two cloth clamping mechanisms of embodiment 1 and a driving mechanism 3 .

[0055] In the embodiment of the present disclosure, at least two cloth clamping mechanisms are provided, and different cloth clamping mechanisms are located at different sides. Therefore, when the folded edges 5 on different sides are folded, the cloth clamping mechanisms located at the corresponding sides can clamp the folded edges 5 on different sides to prevent the folded edges 5 on different sides from rebounding.

[0056] At the same time, since the opening size required in different scenes is different, based on this, in order to make the opening size different, the cloth clamping mechanism can also clamp the folded edge 5, and each cloth clamping mechanism in the embodiment of the present disclosure is respectively connected to a driving mechanism 3, such as Figure 6 As shown. The driving mechanism 3 can be a telescopic cylinder, which can be a telescopic air cylinder or a telescopic oil cylinder. The tail end of the telescopic cylinder is fixedly installed, and can be installed on a rack or other position. The front end of the telescopic cylinder is connected to the mounting plate in the cloth clamping mechanism. When the telescopic cylinder performs telescopic movement, the cloth clamping mechanism also performs telescopic movement, and the cloth clamping mechanism changes the position of the cloth.

[0057] It should be noted that: in the embodiment of the present disclosure, the driving mechanism 3 is preferably a telescopic cylinder, but the driving mechanism 3 can also be a conventional driving device in the prior art such as a driving motor. For example, when the driving mechanism 3 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 of the cloth clamping mechanism, 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 cloth clamping mechanism to change. Example 3

[0058] The disclosed embodiment provides a bag opening machine, which includes the cloth clamping device, the edge folding device and the frame of Example 2. The cloth clamping device and the edge folding device 5 are both installed on the frame, which can be a bag opening machine frame in the prior art, not shown in the figure.

[0059] In the embodiment of the present disclosure, the cloth clamping device and the folding device 5 4 are respectively installed in a top-bottom cooperation manner. Figure 7 As shown, a protrusion 41 is provided at the bottom edge of the hem folding device 4. When the hem folding device 4 moves under the drive of the power module 2, the protrusion 41 at the edge of the hem folding device 4 pushes the hem 5, so that the hem 5 is folded. The folded hem 5 is adapted to the cloth clamping device, so that the hem 5 is fixed.

[0060] The power module 2 in the embodiment of the present disclosure may be a power mechanism in the prior art, such as a robotic arm.

[0061] 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.

[0062] 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.
