Description

Technical Field

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

[0002] When the bag opening machine is processing and making the bag lip, a hole will be cut in the fabric, and after the hole is cut, a fold will be formed on the fabric. After the fold is folded and sewn, the edge of the bag lip can be made smoother. After the fold is folded, the fold needs to be bent, and the fold needs to be pressed tightly with a lower pressure plate and a pressure frame to facilitate the sewing machine head to sew the fold and the fabric. The movement of the lower pressure plate is usually driven by a structure such as a cylinder or an electric cylinder, so a telescopic structure such as a cylinder or an electric cylinder needs to be connected to the lower pressure plate.

[0003] However, other structures need to be installed on the upper side of the lower pressing plate, such as a slidable push-pull plate, which is used to assist the folding and bending. At this time, if the telescopic structure is directly connected to the lower pressing plate, the telescopic structure will be located directly above the lower pressing plate, which seriously affects the installation of the push-pull plate. Utility Model Content

[0004] The utility model provides a lifting module, a folding matching device and a bag opening machine, which are used to solve the problem that the telescopic mechanism affects the installation of structures such as a push-pull plate on the upper side of a lower pressing plate.

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

[0006] A lifting module comprises a telescopic mechanism, a guiding mechanism and a connecting part, wherein the telescopic mechanism comprises a fixed part and a movable part, the guiding mechanism is slidably connected with the fixed part, and the movable part and the guiding mechanism are respectively connected with the connecting part.

[0007] In this solution, since the telescopic mechanism is connected to the guide mechanism through a connecting part, power can be transmitted to other structures such as the lower pressure plate through the guide mechanism. Therefore, the telescopic mechanism does not need to be installed directly above the lower pressure plate, thereby solving the problem of the telescopic mechanism occupying the upper space of the lower pressure plate and affecting the installation of structures such as the push-pull plate on the upper side of the lower pressure plate.

[0008] Preferably, guide mechanisms are respectively provided on both sides of the telescopic mechanism.

[0009] In this solution, since the lower pressure plate needs to cooperate with the pressure frame on one side to press the folded edge, the lower pressure plate is subjected to uneven force for a long time. Providing guide mechanisms on both sides of the telescopic mechanism can increase the stability of the lower pressure plate and prevent the lower pressure plate from tilting due to uneven force.

[0010] Preferably, the guide mechanisms on both sides of the telescopic mechanism are symmetrically arranged.

[0011] In this solution, the two guide mechanisms are symmetrically arranged on both sides of the telescopic mechanism, so that the two guide mechanisms can be evenly stressed, avoiding unbalanced loading of the guide mechanisms and preventing the lower pressure plate from deflecting.

[0012] Preferably, the connecting portion is connected to two guide mechanisms at the same time.

[0013] In this solution, one connecting part is used to connect two guide mechanisms, which can make the structure more compact.

[0014] Preferably, the connecting portion is a strip structure, a boss is provided on one side of the strip structure, and the telescopic mechanism is connected to the boss.

[0015] In this solution, since the connecting portion needs to connect two guide mechanisms at the same time and the telescopic mechanism is located offset from , a boss can be provided on the connecting portion so that the telescopic mechanism can transmit power to the two guide mechanisms through the boss.

[0016] Preferably, the guide mechanism includes a guide rod, the fixed portion is provided with a guide hole, and the guide rod is slidably connected to the guide hole; or, the guide structure includes a guide rail, a slider is provided on the side of the fixed portion, and the guide rail is slidably connected to the slider.

[0017] In this solution, the above two structures can be used as guide mechanisms, and both can transmit the power transmitted by the connecting part to other positions.

[0018] Preferably, the fixing portion is provided with a mounting hole, a detachable sleeve is provided in the mounting hole, and the guide hole is an inner hole of the sleeve.

[0019] In this solution, the sleeve can be removed and replaced from the mounting hole. When the guide hole has been worn for a long time and its accuracy has decreased, the problem of low guide rod accuracy can be solved by replacing the sleeve. The cost of replacing the sleeve is lower, which reduces maintenance costs.

[0020] The utility model also provides a folding matching device, including the above-mentioned lifting module, and also including a bracket and a lower pressing plate, the fixing part of the lifting module is connected to the bracket, and the bottom end of the guide mechanism is connected to the lower pressing plate. In this solution, the lower pressing plate and the bracket are connected through the lifting module, so that the lifting module can be deviated from the upper side of the lower pressing plate, which is convenient for installing other structures on the upper side of the lower pressing plate. Preferably, the lower pressing plate is provided with a telescopic mechanism and a guiding mechanism on both sides.

[0021] In this solution, telescopic mechanisms and guide mechanisms are respectively arranged on both sides of the lower pressing plate, so that the force on the lower pressing plate can be more evenly applied, thereby preventing the lower pressing plate from tilting left and right due to uneven force.

[0022] The utility model also provides a bag opening machine, comprising the above-mentioned lifting type pressing frame module.

[0023] In this solution, the position of the telescopic mechanism can be offset to both sides of the lower pressure plate, which will not affect the installation of structures such as the push-pull plate, and is more convenient for installing other structures on the upper side of the lower pressure plate.

[0024] Beneficial effects of the utility model:

[0025] In the utility model, since the telescopic mechanism is connected to the guide mechanism through the connecting part, the power can be transmitted to other structures such as the lower pressure plate through the guide mechanism. Therefore, the telescopic mechanism does not need to be installed directly above the lower pressure plate, thereby solving the problem that the telescopic mechanism occupies the upper space of the lower pressure plate and affects the installation of structures such as the push-pull plate on the upper side of the lower pressure plate.

When the electric cylinder or the pneumatic cylinder is working, it will not extend downward, so as to avoid blocking the lower pressing plate 9 or the bottom of the entire pressing frame module.

[0038] The telescopic mechanism 2 includes a fixed part 7 and a movable part. It is understandable that the fixed part 7 is a fixed part used for fixed connection with other mechanisms, while the movable part is used for transmitting power to other structures. For example, when the telescopic mechanism 2 adopts a cylinder, the cylinder barrel is connected to other frames, the cylinder barrel is fixed and is the fixed part, and the piston rod is the movable part. It should be noted that the structure fixedly connected to the cylinder barrel can belong to the scope of the fixed part.

[0045] When only one guide rod 5 is connected to the telescopic mechanism 2 , the strip structure is in a straight line shape, and at this time, both ends of the strip structure are connected to the telescopic mechanism 2 and the guide rod 5 respectively.

[0046] When guide mechanisms are respectively provided on both sides of the telescopic mechanism 2 , the strip structure is similar to a T-shape, a boss 3 is provided on one side of the strip structure, both ends of the strip structure are respectively connected to two guide rods 5 , and the boss 3 is connected to the telescopic mechanism 2 .

During operation, the slider remains in a fixed position, while the slide rail slides up and down relative to the slider. The sliding direction of the slide rail is vertical, so that the lower pressure plate 9 can be raised and lowered.

[0052] Embodiment three.

[0053] The third embodiment provides a lifting module. The difference from the first embodiment is that the third embodiment further includes a push-pull plate 11 .
