Embodiment Construction

[0036] refer to Figure 1 ~ Figure 4 , the present invention is a bag-making machine with a middle seal and a valve, which includes:

[0037] The discharge rack device 1 is used to continuously and stably provide the film O to the subsequent process; the discharge rack device 1 may specifically include a discharge roller 11, a magnetic powder brake 12, an electromagnetic brake 13, a first tension swing roller assembly 14 and a potentiometer , the first tension pendulum roller 14 is used to control the tension of the film and store a certain length of film, the potentiometer is used to measure the displacement of the first tension pendulum roller assembly 14, and convert the data into a signal for controlling the magnetic powder brake 12, the magnetic powder brake 12 can control the rotation resistance of the discharge roller 11, and then achieve a closed-loop control of film zero tension;

[0038] The valve adding device 2 is used to add the one-way venting valve 62 to the sp...

Abstract

The invention discloses a medium-sealing valve-adding bag-making machine. The medium-sealing valve-adding bag-making machine sequentially comprises a feeding frame device, a valve adding device, a folding forming device, a longitudinal sealing device, a transverse sealing device, a second traction group and a cutter device in the moving direction of films, wherein the feeding frame device is used for continually and stably providing the films for follow-up procedures; the valve adding device is used for additionally mounting one-way ventilation valves in set positions on the films; the folding forming device is used for continuous folding forming of the valve-added films, and can fold the films on two sides to the middle and overlap the films in the middle positions; the longitudinal sealing device is used for longitudinal heat-sealing of the folded films at the overlapping parts; the transverse sealing device is used for transverse heat-sealing of the folded films which are processed by the longitudinal sealing device; the second traction group is used for providing power for movement of the films; the cutter device is used for cutting the well processed films to form end products. The medium-sealing valve-adding bag-making machine can be obtained by modifying a traditional medium-sealing bag making machine, thereby having extremely high economic benefits; the medium-sealing valve-adding bag-making machine is compact in structure, reasonable in technological layout and stable and reliable in production process and greatly lowers the manufacturing cost.

Description

technical field [0001] The invention relates to a bag-making machine with a middle seal and a valve. Background technique [0002] Bags with one-way breathable valve are widely used in coffee packaging, which are mainly reflected in the packaging forms such as middle-sealed and valved bags, middle-sealed organ and valve bags, four-sides-sealed organ and valve bags and other bag types. In the existing bag-making methods for valved bags of this kind of structure, the bag is generally made first, and then the vent valve is manually heat-sealed, which increases the transfer process, increases labor costs and time costs, and reduces bag-making efficiency. Therefore, the present invention provides a center-sealed bag-making machine with an online valve adding device, which can be equipped with a one-way air-ventilating valve while making bags, has high production efficiency, reliable quality, and reduces production costs. Contents of the invention [0003] In order to solve the...
