Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vest bag production, in particular to a transmission and reset structure for the bag head pressing plate of a bag making machine. Background Art
[0002] The bag making machine for vest bags generally includes a plastic film bag making structure, a vest bag folding mechanism, a vest bag bundling structure, etc. In the vest bag folding mechanism, it is necessary to use a pressing plate to press the bag head first and then fold it. In the prior art, the pressing plate is driven by a cylinder to drive a connecting rod to drive the pressing plate to do reciprocating motion. The cylinder is prone to failure after long-term work, resulting in reduced production efficiency and increased costs. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a transmission and reset structure for the bag head pressing plate of a bag making machine realized by a mechanical structure.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] The transmission and reset structure for the bag head pressing plate of a bag making machine includes an eccentric transmission mechanism, a piston rod, a connecting arm, a tension spring, a connecting rod, a reset rod, a rotating shaft, a reset cylinder and a pressing plate. One end of the piston rod is eccentrically rotatably connected to the eccentric transmission mechanism, and the other end is inserted into the connecting arm. The tension spring fixes the piston rod and the connecting arm together. The connecting arm is rotatably connected to the connecting rod, and the connecting rod drives the pressing plate to do reciprocating motion through the rotating shaft. The reset rod is fixed on the rotating shaft and is located between the connecting rod and the pressing plate. The reset cylinder is arranged at the front end of the reset rod.
[0006] Preferably, the connecting arm and the connecting rod are connected through a bearing.
[0007] Preferably, the piston rod and the eccentric transmission mechanism are connected through a bearing.
[0008] Preferably, a shaft is provided at the connection between the piston rod and the eccentric transmission mechanism, a shaft is provided at the connection between the connecting arm and the connecting rod, and the tension spring is hung on the shaft in a stretched state.
[0009] The reset cylinder of the utility model only has an action of ejecting the reset rod and does not drive the pressing plate to do reciprocating motion, and the working intensity is very low, greatly reducing the failure rate. The reciprocating motion of the pressing rod is all driven by mechanical structures such as a tension spring, a connecting arm, a piston rod, a rotating shaft, etc., so the stability and durability are higher, and even if a failure occurs, only the tension spring needs to be replaced, greatly improving the working efficiency and reducing the cost.

[0015] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0016] Reference Figures 1-4 , the bag head pressing plate transmission reset structure of the bag making machine includes an eccentric transmission mechanism 1, a piston rod 2, a connecting arm 10, a tension spring 3, a connecting rod 4, a reset rod 5, a rotating shaft 6, a reset cylinder 8 and a pressing plate 7. One end of the piston rod 2 is eccentrically connected to the eccentric transmission mechanism 1, and the other end is inserted into the connecting arm 10. One end of the transmission shaft 9 is connected to the motor, and the other end is connected to the eccentric transmission mechanism 1. A shaft is fixed on the eccentric transmission mechanism 1, and a bearing is arranged on the shaft, and the piston rod 2 is fixed on the bearing. A shaft is fixed on the connecting rod 4, and a bearing is arranged on the shaft, and the connecting arm 10 is fixed on the bearing. The tension spring 3 is hung on the two shafts in a stretched state. The connecting rod 4 drives the pressing plate 7 to reciprocate through the rotating shaft 6. The reset rod 5 is fixed on the rotating shaft 6 and is located between the connecting rod 4 and the pressing plate 7. The reset cylinder 8 is arranged at the front end of the reset rod 5.
[0017] The structure of the utility model is located in the bag head pressing part of the entire bag making machine. After the vest bag is made through the previous process, it is necessary to press the bag head here and fold it for bundling. There is also a related bag body folding structure near the utility model, which belongs to the part of the prior art and will not be described here. When the utility model is working, the transmission shaft drives the eccentric transmission mechanism to rotate, thereby driving the piston rod and the connecting arm, connecting rod, reset rod, and pressure plate to rotate, and the pressure plate presses the bag head of the vest bag. When the bag head needs to be loosened, the reset cylinder is actuated to hold the reset rod and reverse, and at the same time the tension spring pulls the connecting rod to drive the reset rod and the pressure plate back to the initial position, waiting for the next action.
