Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, and in particular to a bag-blocking lip mechanism and a bag opening machine. Background Technology

[0002] A pocket-opening machine is a machine that uses a folding knife device to fold cut fabric and then sew it together to form a pocket. Figure 1 As shown, existing bag-opening machines sew together three pieces of fabric—a bottom bag, a lip bag, and a fabric bag—to form a bag. The operator places the fabric bag on a clamp, folds the bottom bag and lip bag, and places them on a plastic template 12. The machine first cuts the fabric bag and then moves the clamp to clamping position 13, i.e., on the plastic template 12, so that the three pieces of fabric—bottom bag, lip bag, and fabric bag—are overlapped. The machine then moves back to sew. When using the above-mentioned bag-opening machine, the operator needs to correctly place the bottom bag and lip bag according to the adjusted laser infrared beam. However, considering that there may still be some deviation, leading to defective bags, a lip-blocking mechanism is added. This mechanism moves the limiting baffle 11 to the lip-blocking position by vertical lifting and horizontal movement. When not in use, the limiting baffle 11 is removed, without hindering the cyclical movement of the plastic template 12.

[0003] However, the aforementioned bag-stopping lip mechanism is mounted outside the frame, resulting in a large stroke of the baffle, increased action time, and a large overall size of the bag opener, leading to significant wasted design space and a large footprint. Therefore, a bag-stopping lip mechanism is proposed to address these issues. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 2 and Figure 3 As shown, in order to achieve the above objectives, this utility model provides a bag-blocking lip mechanism, including: a device frame 1 and a connector 2 disposed on the device frame 1, wherein the device frame 1 is used to place the sewing template.

[0026] The connector 2 is slidably set on the inner side of the equipment frame 1. The rotating shaft 3 is rotatably set on the connector 2. The other end of the rotating shaft 3 is set with a limiting baffle 11. By setting the overall bag-blocking lip mechanism on the inner side of the equipment frame 1, the assembly space inside the equipment frame 1 is fully utilized to achieve compactness and miniaturization of the bag-opening machine, effectively reducing the maximum external size of the overall bag-opening machine, reducing the footprint of the bag-opening machine, and thus saving manufacturing costs. Specifically, the lower end of the rotating shaft 3 is connected to the connecting piece 2, and the upper end of the rotating shaft 3 is provided with a limiting baffle 11. The connecting piece 2 can be driven to reciprocate along the axial direction of the rotating shaft to adjust the position of the limiting baffle 11 in the axial direction of the rotating shaft. The rotating shaft 3 can be driven to rotate reciprocally along its own rotation axis to adjust the position of the limiting baffle 11 in the plane. By controlling the combination of the two position adjustment methods of driving the limiting baffle 11 to move linearly in the axial direction of the rotating shaft and rotate in the plane, the travel of the limiting baffle 11 is greatly reduced, the position of the limiting baffle 11 on the equipment frame 1 is flexibly adjusted, and the position adjustment efficiency of the limiting baffle 11 is effectively improved, thereby quickly achieving the function of limiting the bag lip.

[0027] When it is necessary to restrict the bag lip, the control drive connector 2 moves downward along the axis of the rotating shaft to the lower limit position. While the connector 2 moves downward, it drives the rotating shaft 3 and the limiting baffle 11 to move synchronously to the preset height. The control drive rotating shaft 3 rotates forward along its own rotation axis by a preset angle, adjusting the position of the limiting baffle 11 on the plane so that the limiting baffle 11 moves to a position flush with the bag lip, thereby achieving the function of restricting the bag lip.

[0028] In some embodiments of this utility model, an installation plate 4 is provided on the inner side of the equipment frame 1. The installation plate 4 is arranged vertically. A lifting cylinder 5 is provided on the side of the installation plate 4 facing the connector 2. Preferably, the lifting cylinder 5 is located at the bottom of the installation plate 4. By controlling and driving the lifting cylinder 5 to extend the lifting piston rod, the lifting piston rod can support the connector 2 and move it upward along the axis of rotation, thereby driving the rotation axis 3 and the limiting baffle 11 to move upward synchronously. By controlling and driving the lifting cylinder 5 to retract the lifting piston rod, the lifting piston rod can pull the connector 2 downward along the axis of rotation, thereby driving the rotation axis 3 and the limiting baffle 11 to move downward synchronously. By using the lifting cylinder 5 as the power source to directly drive the lifting piston rod to perform lifting and lowering actions, the movement response of the connector 2 and the limiting baffle 11 is rapid, which can effectively improve the efficiency of adjusting the vertical position of the limiting baffle 11.

[0029] In some embodiments of this utility model, at least one slide rail groove 401 is provided on the side of the mounting plate 4 facing the connector 2, and at least one sliding seat 201 is provided on the side of the connector 2 facing the mounting plate 4. Optionally, two parallel slide rail grooves 401 are provided on the side of the mounting plate 4 facing the connector 2, and two parallel sliding seats 201 are provided on the side of the connector 2 facing the mounting plate 4. The sliding seats 201 are slidably connected to the corresponding slide rail grooves 401. Through the sliding cooperation between the sliding seats 201 and the slide rail grooves 401, the path of the connector 2 moving up and down along the axial direction of the rotation axis is effectively limited and corrected, preventing the connector 2 from deviating and shaking during the movement, and improving the stability of the connector 2 during movement. At the same time, by limiting and correcting the movement path of the connector 2, displacement deviation of the limiting baffle 11 can be prevented, thereby improving the position adjustment accuracy of the limiting baffle 11 and ensuring that the limiting baffle 11 can move to a position flush with the bag lip, so as to accurately achieve the function of limiting the bag lip.

[0030] In some embodiments of this utility model, a swing cylinder 6 is provided on the side of the connector 2 facing away from the mounting plate 4. The first end of the swing cylinder 6 is rotatably connected to the first end of the connector 2, and the second end of the swing cylinder 6 is rotatably connected to the first end of the rotating shaft 3. Specifically, the left end of the swing cylinder 6 is rotatably connected to the left end of the connector 2, and the right end of the swing cylinder 6 is rotatably connected to the lower end of the rotating shaft 3. Preferably, the swing cylinder 6 is located at the bottom of the mounting plate 4. By controlling the swing cylinder 6 to extend its swing piston rod, the rotating shaft 3 and the limiting baffle 11 are driven to rotate in the forward direction. By controlling the swing cylinder 6 to retract its swing piston rod, the rotating shaft 3 and the limiting baffle 11 are driven to rotate in the reverse direction. The swing cylinder 6 directly drives the limiting baffle 11 to perform bidirectional movements through the rotating shaft 3, improving the flexibility of the rotation adjustment of the limiting baffle 11 and increasing the accuracy of the angle adjustment of the limiting baffle 11, effectively ensuring the long-term stable operation of the bag lip mechanism.

[0031] In some embodiments of this utility model, a hinge 7 is provided at the first end of the connecting member 2. The hinge 7 is connected to the first end of the swing cylinder 6 via a pin. Specifically, the hinge 7 is provided at the left end of the connecting member 2. The hinge 7 provides a stable rotation fulcrum for the swing cylinder 6, effectively ensuring accurate and error-free power transmission between the swing cylinder 6 and the connecting member 2. This adapts to the angle change of the swing cylinder 6 relative to the side of the connecting member 2 during operation, avoiding rigid interference between the swing cylinder 6 and the connecting member 2 during rotation, ensuring the normal operation of the swing cylinder 6, and improving the structural stability of the overall bag-stopping lip mechanism. Moreover, the hinge 7 is connected to the left end of the swing cylinder 6 via a pin, enabling quick assembly and disassembly between the connecting member 2 and the swing cylinder 6, providing convenience for later maintenance and repair.

[0032] In some embodiments of this utility model, at least one fixed seat 202 is provided at the second end of the connecting member 2. The fixed seat 202 has an assembly hole, and a bearing 8 is sleeved on the first end of the rotating shaft 3, with the bearing 8 embedded in the assembly hole. Specifically, two fixed seats 202 are provided at the right end of the connecting member 2, forming a stable support structure to reliably limit the rotation of the rotating shaft 3, suppressing radial offset and swaying during rotation or vertical movement, and improving the stability of the rotating shaft 3 during rotation. Simultaneously, two bearings 8 are sleeved on the lower end of the rotating shaft 3, with each bearing 8 correspondingly embedded in the assembly hole of the fixed seat 202. Compared to traditional sliding contact, this reduces the frictional resistance between the fixed seat 202 and the rotating shaft 3, making the rotation of the rotating shaft 3 smoother, reducing power loss, and decreasing wear between the rotating shaft 3 and the fixed seat 202, extending the service life of the fixed seat 202 and the rotating shaft 3, and further ensuring the long-term stable operation of the bag-stopping lip mechanism.

[0033] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a fisheye connector 9 is connected to the lower end of the rotating shaft 3. The other end of the fisheye connector 9 is connected to the right end of the swing cylinder 6 via a rotating shaft. The fisheye connector 9 acts as a lever to ensure that there is a certain distance between the rotation axis of the rotating shaft 3 and the force point of the rotating shaft 3 in the radial direction of the rotating shaft 3. When the swing piston rod extends or retracts, it can generate sufficient driving torque to drive the rotating shaft 3 to rotate normally. At the same time, the fisheye connector 9 can adapt to the angle change between the swing piston rod and the rotating shaft 3 during the extension and retraction process, avoiding rigid interference caused by contact between the swing piston rod and the rotating shaft 3, and further improving the accuracy of the rotation adjustment of the rotating shaft 3 and the limiting baffle 11.

[0034] In some embodiments of this utility model, the first end of the rotating shaft 3 is provided with an assembly groove 301, the surface of the assembly groove 301 is provided with a threaded hole, and the first end of the fisheye connector 9 is provided with a connecting hole. Optionally, the fastener is a bolt, and the fastener passes through the connecting hole and is threaded to the threaded hole. The opening of the assembly groove 301 provides a positioning reference for the installation of the fisheye connector 9, so that the fisheye connector 9 can be quickly aligned and assembled with the rotating shaft 3, effectively improving the assembly efficiency and assembly accuracy of the fisheye connector 9.

[0035] In some embodiments of this utility model, a connecting block 10 is provided at the upper end of the rotating shaft 3. The left end of the connecting block 10 is connected to the rotating shaft 3 by a fastener, and the right end of the connecting block 10 is connected to the limiting baffle 11 by a fastener. Optionally, the fastener is a bolt. The connecting block 10 plays a certain intermediate transition role to compensate for the installation and adaptation gap between the rotating shaft 3 and the limiting baffle 11, improve the connection accuracy between the rotating shaft 3 and the limiting baffle 11, and effectively ensure that the limiting baffle 11 and the rotating shaft 3 maintain synchronous operation. At the same time, the setting of the connecting block 10 can disperse the interaction force between the limiting baffle 11 and the rotating shaft 3, avoid local stress concentration in the limiting baffle 11 or the rotating shaft 3, which would cause excessive local stress and deformation damage to the rotating shaft 3 or the limiting baffle 11, thereby enhancing the structural strength of the bag-blocking lip mechanism.

[0036] The working principle of this utility model is as follows: In the initial state, the limiting baffle 11 is flush with the inner side of the equipment frame 1, and the limiting baffle 11 is in the upper limit position to ensure that it does not interfere with other mechanisms. When it is necessary to restrict the bag lip, the control of the drive lifting cylinder 5 retracts the lifting piston rod. The lifting piston rod can pull the connecting piece 2 to move downward along the axis of the rotating shaft, thereby driving the rotating shaft 3 and the limiting baffle 11 to move downward synchronously to a preset height. At the same time, the control of the drive swing cylinder 6 extends the swing piston rod to drive the rotating shaft 3 and the limiting baffle 11 to rotate forward by a preset angle to adjust the position of the limiting baffle 11 on the plane, so that the limiting baffle 11 moves to a position flush with the bag lip, thereby achieving the function of restricting the bag lip.

[0037] In addition to the bag-blocking lip mechanism described above, this utility model also provides a bag-opening machine that includes the bag-blocking lip mechanism disclosed in the above embodiments. For the structure of other parts of the bag-opening machine, please refer to the prior art, which will not be described in detail here.

[0038] In summary, by setting the overall bag-blocking lip mechanism on the inner side of the equipment frame 1, the assembly space inside the equipment frame 1 is fully utilized, thereby achieving a compact and miniaturized bag-opening machine, effectively reducing the maximum external dimensions of the overall bag-opening machine, reducing the footprint of the bag-opening machine, and thus saving manufacturing costs.
