Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machines, and specifically provides a new bag opening machine. Background Art

[0002] The bag opening machine can make the fabric into a bag opening. When the bag opening machine processes the bag opening, it needs to cut the bag opening to form an opening. When cutting, a folded edge will be formed at the opening. In the subsequent process, the bag opening machine will fold the folded edge through a folding device, fold the folded edge to overlap with the fabric, and then sew the folded edge to the fabric through a sewing mechanism to form a flat bag opening. The existing folding device usually presses the folded edge from the top side through an L-shaped structure, and the L-shaped structure then moves horizontally to push the folded edge, so that one side of the folded edge fabric is folded. After the folded edge is folded, the bag opening machine presses the folded edge from the bottom side through a folding matching module, so that the folded edge is pressed to a state parallel to the fabric. After the folded edge is pressed, it can be sewn by the sewing head of the bag opening machine.

[0003] However, the width of the bag mouth is not the same. After the width of the bag mouth changes, the position of the folding matching module used to assist in folding in the y direction also needs to be changed. For example, replace the folding matching modules of different sizes. However, after the position of the folding matching module in the y direction is changed, the folding device is obviously spaced from the folding matching module, and cannot cooperate with the folding matching module to achieve folding and pressing the folding, so it is also necessary to replace or adjust the position of the folding device in the y direction. Therefore, when processing bag mouths of different widths, the entire debugging operation is very cumbersome and the debugging operation efficiency is very low, which needs to be solved urgently. Utility Model Content

[0004] The utility model provides a novel bag opening machine, which is used to solve the problem that when processing bag openings of different widths, the whole debugging operation is very complicated and the debugging operation efficiency is very low.

[0005] The technical solution of the utility model is as follows:

[0006] A bag opening machine comprises a y-axis module, a folding frame pressing device and a frame, wherein the folding frame pressing device comprises a y-direction folding matching unit, the y-direction folding matching unit comprises folding matching modules relatively arranged along the y direction, the y-axis module is arranged on the frame, the folding frame pressing device is transmission-connected to the y-axis module, and the y-axis module is used to adjust the position of the folding frame pressing device in the y direction.

[0007] In this solution, the folding frame pressing device can be controlled to move along the y direction through the y-axis module, so that the y-direction folding matching module can be moved toward the folding module, so that the folding module can cooperate with the y-direction folding matching module on one side to achieve folding and pressing the folded edge on one side of the bag opening. After the y-direction folding matching module on one side presses the folded edge, the y-axis module moves in the opposite direction along the y direction, so that the y-direction folding matching module on the other side approaches the folding module, so as to achieve folding and pressing the folded edge on the other side of the bag opening. Therefore, even if the width of the bag opening changes, this solution only needs to adjust the movement spacing of the y-axis module each time, so that the y-direction folding matching module can cooperate with the folding module to complete the folding work of the bag opening, without adjusting the position of the folding module, which solves the problem that the entire debugging operation is very cumbersome and the debugging operation efficiency is very low when processing bag openings of different widths.

[0008] Preferably, the y-axis module includes a drive motor and a linear transmission mechanism, the drive motor is transmission-connected to the linear transmission mechanism, the linear transmission mechanism is transmission-connected to the folding frame pressing device, and the drive motor is arranged on the frame.

[0009] In this solution, the y-axis module can drive the folding and pressing frame device to move linearly along the y direction, thereby adjusting the position of the folding and pressing frame device in the y direction.

[0010] Preferably, the linear transmission mechanism includes a belt transmission mechanism, a screw-nut transmission mechanism, or a gear rack transmission mechanism.

[0011] Preferably, the y-axis module belt transmission mechanism comprises a first belt, a driving motor and a connecting part, the driving motor and the first belt are arranged on a frame, the driving motor is connected to the first belt transmission, the output shaft of the driving motor is perpendicular to the y direction, the first belt connecting part is connected to the first belt, and the folding frame pressing device is connected to the connecting part.

[0012] In this solution, a first belt and a connecting part are used to transmit the power of the driving motor, which frees up the installation position of the driving motor and allows the output shaft of the driving motor to be perpendicular to the y-axis module. Thus, the driving motor can be installed in the length direction of the frame, reducing the center of gravity offset of the frame caused by the driving motor, thereby reducing the vibration generated when the folding frame pressing device moves.

[0013] Preferably, the y-axis module also includes a linear guide rail arranged along the y direction, and the folding frame pressing device is connected to the frame through the linear guide rail.

[0014] In this solution, the linear guide rail is provided to constrain the moving direction of the edge folding and pressing frame device, so that the edge folding and pressing frame device moves along a straight line.

[0015] Preferably, the folding and framing device further includes an x-direction folding matching unit.

[0016] In this solution, an x-direction folding cooperation unit is provided to cooperate with the folding module to fold and press the folding in the x-direction.

[0017] Preferably, the folding frame pressing device also includes a bracket and a driving power, the y-axis module is transmission connected to the bracket, the y-direction folding matching module is slidingly connected to the bracket, the driving power is transmission connected to the y-direction folding matching module, and the driving power drives the two y-direction folding matching modules to move synchronously in opposite directions.

[0018] In this solution, the y-direction folding matching module is slidably connected to the bracket, so that the spacing between the y-direction folding matching modules can be adjusted. When processing bags of different sizes, there is no need to replace the y-direction folding matching modules, which improves the debugging efficiency, reduces the debugging operation steps, and thus reduces the debugging difficulty. Setting a driving power to drive the y-direction folding matching module improves automation. Compared with manual adjustment, automatic adjustment can achieve more efficient and precise adjustment.

[0019] Preferably, the two Y-direction folding matching modules are connected to the same driving power transmission.

[0020] In this solution, the same driving force is used to drive the Y-axis folding matching module to move, which can not only achieve the purpose of reducing costs, but also avoid the problem of low precision caused by the superposition of errors of the two forces.

[0021] In this solution, the first belt and the connecting part are used to transmit the power of the driving motor, which frees up the installation position of the driving motor, and allows the output shaft of the driving motor to be parallel to the x-axis module, so that the driving motor can be installed on the second vertically arranged mounting frame, reducing the center of gravity offset caused by the driving motor, thereby reducing the vibration generated when the slide slides. When the hemming pressing frame device is connected and driven to move, the vibration of the hemming pressing frame device can be reduced, thereby avoiding the position offset of the bag cloth or zipper to be sewn, and preventing the bag cloth or zipper from being sewn in the wrong position.

[0022] Preferably, it also includes a tensioning wheel, which is connected to the frame and is used to tension the first belt (7).

[0023] In this solution, a tensioning wheel is provided to tighten the first belt, thereby ensuring that the movement of the connecting block is a linear movement, thereby improving the accuracy of the position of the connecting block.

[0024] Preferably, the first belt includes a horizontal section, the horizontal section is parallel to a horizontal plane, and the connecting portion is arranged on the horizontal section.

[0025] In this solution, the horizontal section remains horizontal, ensuring that the y-axis module can accurately move the connecting block horizontally in the front-to-back direction, thereby ensuring that the folding frame pressing device connected to the connecting block can maintain horizontal front-to-back movement.

[0026] Beneficial effects of the utility model:

[0027] The utility model can control the movement of the folding and pressing frame device along the y direction through the y-axis module, so that the y-direction folding cooperation module can move toward the folding module, so that the folding module can cooperate with the y-direction folding cooperation module on one side to realize the folding and pressing of the folding edge on one side of the bag opening. Even if the width of the bag opening changes, the present invention only needs to adjust the moving spacing of the y-axis module each time, so that the y-direction folding cooperation module can cooperate with the folding module to complete the folding work of the bag opening without adjusting the position of the folding module, thus solving the problem of needing to adjust the position of the folding module when processing bag openings of different widths and low debugging operation efficiency.

[0039] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0040] Embodiment 1.

[0041] like Figure 1 As shown, the first embodiment provides a novel bag opening machine, comprising a frame 1, a y-axis module 3 and a folding frame pressing device 2, wherein the y-axis module 3 is arranged on the frame 1, the folding frame pressing device 2 is transmission-connected with the y-axis module 3, and the folding frame pressing device 2 can be moved along the y direction through the y-axis module 3. The y direction refers to a direction parallel to the y-axis module 3, that is, parallel to the width direction of the bag opening prepared by the bag opening machine.

[0042] like Figure 2 and Figure 3 As shown, the folding frame pressing device 2 includes a y-direction folding matching unit, which includes folding matching modules relatively arranged along the y direction, and the y-axis module 3 is used to adjust the position of the folding frame pressing device 2 in the y direction.

[0043] Existing bag opening machines are all provided with a folding module, which is used to cooperate with the y-direction folding cooperation unit to realize the folding of the bag opening in the y direction, and to realize the compression of the folded edge through the y-direction folding cooperation unit.

[0044] The hemming and pressing frame device 2 further comprises a bracket 7, and the y-direction hemming matching module is slidably connected to the bracket 7. The sliding connection method can make the distance between the two y-direction hemming matching modules adjustable.

[0045] The bracket 7 is provided with a driving power, and the driving power is transmission-connected with the Y-direction folding matching module.

[0046] The driving power can be a servo motor. The transmission mode between the driving power and the Y-direction hemming matching module can be the following two modes.

[0047] In the first mode, the transmission structure between the driving power and the y-direction hemming matching module adopts a screw nut, wherein the screw is fixed to the bracket 7, and the nut is connected to the y-direction hemming matching module. The screw is connected to the driving power by transmission. The screw is provided with external threads in opposite directions, and at least two nuts are provided on the screw, each nut is connected to the external threads in opposite directions. When the screw rotates, the two nuts move in opposite directions, so the y-direction hemming matching module moves in opposite directions.

[0048] The second method, such as Figure 4 As shown, the transmission structure between the driving power and the y-direction hemming matching module adopts a second belt 6, the tight side and the loose side of the second belt 6 are respectively provided with a connecting structure 5, and the two y-direction hemming matching modules are respectively connected to the two connecting structures 5. When the tight side and the loose side of the second belt 6 are parallel, the connecting structures 5 of the tight side and the loose side move in opposite directions at the same speed, so that the two y-direction hemming matching modules move in opposite directions at the same speed.

[0049] The y-direction hemming matching module includes a second lifting mechanism 43, a lower pressing plate 41, a push-pull plate 42 and a lateral pushing mechanism 44. The hemming matching module includes a lower pressing plate 41, a second lifting mechanism 43, a lateral pushing mechanism 44 and a push-pull plate 42. The second lifting mechanism 43 is movably connected to the bracket 7, and the lower pressing plate 41 is connected to the second lifting mechanism 43. The second lifting mechanism 43 is used to adjust the height of the lower pressing plate 41. The second lifting mechanism 43 is connected to the driving power transmission, and the driving power is used to drive the second lifting mechanism 43 to move. The lateral pushing mechanism 44 is connected to the second lifting mechanism 43, and the lateral pushing mechanism 44 is connected to the push-pull plate 42. The lateral pushing mechanism 44 is used to control the lateral movement of the push-pull plate 42. It should be noted that during the up and down movement of the lower pressing plate 41, the height of the lateral pushing mechanism 44 remains unchanged. For example, when a cylinder is used in the second lifting mechanism 43, the cylinder body of the cylinder is slidably connected to the bracket 7. At this time, the lateral pushing mechanism 44 is connected to the cylinder body of the cylinder, and the lower pressing plate 41 is connected to the piston rod of the cylinder.

[0050] The two sides of the lower pressing plate 41 are respectively connected with second lifting mechanisms 43 , and the second lifting mechanisms 43 are respectively slidably connected with the brackets 7 .

[0051] The bracket 7 is provided with a first lifting mechanism, and the pressing frame is connected to the first lifting mechanism. The first lifting bracket 7 is used to adjust the height position of the pressing frame, thereby adjusting whether the pressing frame presses the cloth.

[0052] The second lifting mechanism 43 may include a cylinder, a guide rail and a guide slider, wherein the guide rail is connected to the bracket 7, the guide slider is connected to the lower pressing plate 41, and the guide slider is slidably connected to the guide rail. The two ends of the cylinder are respectively connected to the lower pressing plate 41 and the bracket 7, and are used to drive the lower pressing plate 41 to move up and down. Similarly, the cylinder in the second lifting mechanism 43 may also be replaced by an electric cylinder, and the guide rail and guide slider in the second lifting mechanism 43 may also be replaced by a guide rod and a guide hole. When a guide rod and a guide hole are used, it is necessary to set a mounting block that can open a guide hole, the guide hole is set on the mounting block, and the electric cylinder is fixedly connected to the mounting block.

[0053] The second lifting mechanism 43 can be used to fix the mounting block to the second belt 6, and the connection method can be screw fastening. For example, one side of the mounting block is extended to the position of the second belt 6, and then fasteners such as screws are used to penetrate the second belt 6 and the mounting block, and the second belt 6 and the mounting block are fixed by nuts.

[0054] The lateral pushing mechanism 44 can be a cylinder or an electric cylinder, and a horizontal guide groove is constructed on the second lifting mechanism 43, and the push-pull plate 42 is slidably connected to the guide groove. When a cylinder is used in the second lifting mechanism 43, the guide groove is set on the cylinder body of the cylinder.

[0055] The folding and pressing frame device 2 also includes an x-direction folding matching unit, which includes two relatively arranged x-direction folding matching modules. The x-direction folding matching module can adopt the same structure as the y-direction folding matching module, and is used to press the fold in the x direction of the bag opening.

[0056] like Figure 5 and Figure 6As shown, connected to the folding frame pressing device 2 is a slidable slide arranged on the frame 1, and the y-axis module 3 is arranged on the slide, and the slide also includes an x-axis module and a z-axis module, and the x-axis module is provided with a first mounting frame 11, and the first mounting frame 11 is arranged vertically. The z-axis module is connected to the first mounting frame 11, and the z-axis module is provided with a second mounting frame 12, and the second mounting frame 12 is arranged vertically. The y-axis module 3 is connected to the second mounting frame 12, and the y-axis module 3 is provided with a third mounting frame 16, and the third mounting frame 16 is arranged horizontally. The third mounting frame 16 is provided with a first belt 17, and the y-axis module 3 includes a driving motor 14, and the driving motor 14 is connected to the first belt 17 in transmission connection, and the driving motor 14 is connected to the second mounting frame 12, and the output shaft of the driving motor 14 is parallel to the x-axis module, and the first belt 17 is provided with a connecting portion 18. Therefore, the rotation plane of the first belt 17 is perpendicular to the x-axis module, the moving direction of the connecting portion 18 is always located in the rotation plane of the first belt 17, and the moving direction of the connecting portion 18 is always perpendicular to the x-axis module. If a horizontal section is provided on the first belt 17, the power of the driving motor 14 of the y-axis module 3 can be converted into a linear movement in the direction of the y-axis module 3. In other words, the y-axis module is a linear transmission mechanism including a belt transmission mechanism.

[0057] The third bracket 7 is provided with a horizontal portion on the top, and the horizontal portion is parallel to the horizontal plane. The horizontal portion is provided with a strip hole, which passes through the upper and lower sides of the horizontal portion. The position of the connecting portion 18 corresponds to the position of the strip hole, and other structures can be connected to the connecting portion 18 through the strip hole. For example, the folding frame pressing device 2 can be connected to the connecting portion 18 through the strip hole.

[0058] The connecting portion 18 is provided with a first connecting hole 15, and the first connecting hole 15 can be used to connect the folding frame pressing device 2. By passing a fastener through the first connecting hole 15 and connecting the fastener to the folding frame pressing device 2, a fixed connection between the connecting portion 18 and the folding frame pressing device 2 can be achieved.

[0059] There are several first connection holes 15 on the connection portion 18 , for example, there can be one, two, three or more first connection holes 15 .

[0060] The connecting portion 18 is fixedly connected to the first belt 17. This embodiment 1 provides two connecting methods.

[0061] like Figure 7As shown, the first connection method can be fixed by bolts. The connecting portion 18 includes a connecting block 81 and a bolt. A through hole is opened on the first belt 17, and the through hole passes through the upper and lower sides of the first belt 17. A second connecting hole 16 is set on the connecting portion 18. The bolt passes through the second connecting hole 16 and the through hole, and then a nut is used to cooperate with the bolt to fix the connecting block 81 to the first belt 17. This method can ensure that the connecting portion 18 is stably connected to the first belt 17 to avoid slipping, and can be applicable to a heavy structure such as the folding frame pressing device 2, so it is used as a preferred connection method.

[0062] like Figure 8 As shown, the structure of the connection part 18 of another connection method is different. The connection part 18 includes two connection blocks 81. The two connection blocks 81 are both provided with second connection holes 16. The two connection blocks 81 are respectively provided on the upper and lower sides of the first belt 17. The two connection blocks 81 clamp the first belt 17 from the upper and lower sides respectively, so that the first belt 17 can move with the connection blocks 81. The pre-tightening force of the two connection blocks 81 clamping the first belt 17 is provided by bolts. The bolts are respectively passed through the second connection holes 16, and then a nut is used to connect the two connection blocks 81. Tightening the nut can keep the two connection blocks 81 clamped to the first belt 17.

[0063] The top of the third mounting frame 16 is provided with a y-axis guide rail 20, on which a slidable y-axis slider 19 is provided, and the y-axis slider 19 is slidably connected to the y-axis guide rail 20. The y-axis slider 19 can be used to connect with the folding frame pressing device 2. The y-axis guide rail 20 is perpendicular to the x-axis module, and the y-axis guide rail 20 is parallel to the horizontal plane. The y-axis guide rail is a linear guide rail.

[0064] The third mounting frame 16 is provided with a tensioning wheel 21. In one mounting method, the third bracket 7 is provided with a bearing seat, and the axle of the tensioning wheel 21 is rotatably connected to the bearing seat.

[0065] In another installation mode, the axle of the tension wheel 21 is rotatably connected to an adjusting screw, and an adjusting screw hole is provided on the third mounting frame 16, and the adjusting screw is connected to the adjusting screw hole. The axis of the adjusting screw is located in the rotation plane of the first belt 17, and the adjusting screw is perpendicular to the rotation tangent of the first belt 17. The tension of the tension wheel 21 on the first belt 17 can be adjusted by turning the adjusting screw, so that the first belt 17 is straightened and the connecting portion 18 keeps moving in a straight line.

[0066] It should be noted that the Y-axis module may also use a linear transmission mechanism such as a screw-nut transmission mechanism or a gear rack transmission mechanism to replace the above-mentioned belt transmission mechanism.

[0067] The third mounting frame 16 is perpendicular to the second mounting frame 12 , so a reinforcing rib 22 may be provided between the third mounting frame 16 and the second mounting frame 12 .

[0068] The driving motor 14 of the y-axis module 3 is a servo motor. The x-axis module and the z-axis module are respectively provided with driving motors 14, and the driving motors 14 are all servo motors, which facilitates accurate control of the moving distance of the stability slide.

[0069] The first mounting frame 11, the second mounting frame 12 and the third mounting frame 16 may all be plate-shaped structures, may also be frame structures formed by welding profiles, or may be a combination of a plate-shaped structure and a frame structure.

The servo motor is fixedly connected to the first mounting frame 11.

[0072] The bag opening machine further comprises a sewing head and a cutting head, which are respectively arranged on the upper side of the working platform. The cutting head is used to cut out an opening. When the cutting head cuts out an opening, a folded edge is formed at the opening, and the folded edge can be sewn by the sewing head after being folded, so as to sew a bag opening.

[0073] During operation, the hemming module can be used to push the hemming downward from top to bottom. L-shaped structures are provided on both sides of the bottom of the hemming module, and then the y-axis module 3 pushes the hemming pressing frame device 2 to move, so that a y-direction hemming auxiliary module 4 moves toward the hemming module and presses the hemming against the side of the hemming module. When the hemming is pressed against the side of the hemming module, the hemming is blocked by the lower side of the L-shaped structure, so that the hemming is folded in the horizontal direction, and then the second lifting mechanism 43 of the y-direction hemming auxiliary module 4 drives the lower pressing plate 41 to move upward, so that the lower pressing plate 41 moves upward to press the hemming, and the fixing of the hemming is realized. Then, the y-axis structure moves in the opposite direction, so that the y-direction hemming auxiliary module 4 on the other side presses the hemming on the other side against the L-shaped structure on the other side of the hemming module, and the action of the lower pressing plate 41 is repeated, so as to realize the pressing of the hemming on the other side of the bag opening. After the hemming on both sides of the bag opening is pressed, sewing can be performed by the sewing machine head to complete the processing of the bag opening.
