Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a bag making machine with a material gathering function. Background Art

[0002] Bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is various sizes, thicknesses and specifications of plastic or other material packaging bags. The processing flow of plastic packaging bags mainly includes the steps of transmission, cutting, melting and forming. Among them, the melting forming process is to use a special hot melt mold to melt the cut bag body to repair the bag mouth and bag handle.

[0003] In the above-mentioned fusing forming process, the bag body is melted and repaired to produce waste, which usually needs to be recycled and reshaped to save resources. In the existing recycling process, the residual waste is pushed into the waste bin by the clamp. During the process of pushing the material by the clamp, on the one hand, the material is easy to fall into the recycling bin, and on the other hand, the discrete waste has a high expansion degree and occupies a large space in the recycling bin, which requires regular discharge.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1 and Figure 2 The utility model provides a bag making machine with a material collecting function, which includes a residual waste discharge port 1 arranged at the front end of a fusing forming platform 01 and a waste collecting device 2 located below the residual waste discharge port 1; the fusing forming platform 01 includes a support platform 011, a punching seat 012 arranged above the support platform 011 and moving longitudinally, and a clamping jaw seat 013 moving laterally; wherein the punching seat 012 and the clamping jaw seat 013 are both driven by a driving member (electric cylinder, air cylinder or oil cylinder) to work; at least one group of clamping jaws are arranged on the clamping jaw seat 013, and the clamping jaws are also driven by the driving member (electric cylinder, air cylinder or oil cylinder) to work (it needs to be explained that the clamping jaw seat 013, the punching seat 012 and other components and their connecting structures included in the fusing forming platform 01 are all prior art).

[0020] In the specific operation, first, the moving clamp seat 013 moves the bag body cut off in the previous process to the support platform 011 through the clamp, and then the punching seat 012 descends and uses the hot melt knife with a specific shape at its working end to trim the bag mouth and bag handle. Then, the clamp seat 013 moves the trimmed bag to the next process. After the placement is completed, the clamp seat 013 moves the next group of bag body originals to the support platform 011 again, and in the process of moving, pushes the residual waste left by the previous group into the residual waste discharge port 1.

[0021] At least two groups of collecting rollers 3 whose outer surfaces are in contact with each other are arranged between the residual waste discharge port 1 and the waste collecting device 2, and the multiple groups of collecting rollers 3 are rotatably installed on the bracket 00; the transmission ports between the collecting rollers 3 correspond to the waste collecting device 2. Specifically in the present embodiment, two groups of collecting rollers 3 are arranged.

[0022] During operation, the two groups of collecting rollers 3 rotate relative to each other, and the upper surfaces of the two rollers in the rotating state enter the meshing axis position from the outside (as shown in the figure, the collecting roller 3 at the left end position rotates clockwise, and the collecting roller 3 at the right end position rotates counterclockwise). The two groups can play a role in gathering materials, that is, the rotation can gather the residual waste pushed by the clamping claw seat 013 to any position of the residual waste discharge outlet 1 to the meshing axis position. At the same time, the residual waste is squeezed (flattened) by the collecting rollers 3 to reduce the expansion of the residual waste, reduce the area occupied by it in the waste collection device 2, and further reduce the discharge frequency of the material in the waste collection device 2. The multiple groups of collecting rollers 3 are connected to each other through a gear structure (see Figure 3 ), wherein the rotating shafts of a set of collecting rollers 3 are connected to a driving motor.

[0023] Preferably, the meshing axes corresponding to the two groups of collecting rollers 3 are aligned with the center of the residual waste discharge port 1 to optimize the material gathering effect.

[0024] Preferably, in order to optimize the squeezing (flattening) effect of the collecting roller 3, a heating layer is provided inside the outer wall of the collecting roller 3 of the utility model (a heating plate can be added inside the outer wall of the collecting roller 3), and the heating layer adopts an electric heating method. By heating (heating to a predetermined temperature, but the temperature cannot be higher than the melting temperature of the plastic bag body), the molecular structure of the plastic residue is changed to shrink it.

[0025] See also Figure 2 and Figure 4 The heating layer is connected to the contact terminal 4 fixed on the rotating shaft of the collecting roller 3 through the internal circuit; the bracket 00 is equipped with a conductive ring 5 that contacts with the contact terminal 4, and the conductive ring 5 is fixedly installed on the bracket 00, and the conductive ring 5 is connected to the external power supply device. In the process of transmitting electric energy to the collecting roller 3, the power supply device transmits electric energy to the conductive ring 5, and the rotating shaft of the rotating collecting roller 3 contacts the conductive ring 5 through the contact terminal 4 to achieve power conduction.

[0026] In addition, the waste collecting device 2 uses a nylon bag, and the bracket 00 is provided with a accommodating suspension hook for hanging the nylon bag, so that the residual waste can be easily discharged through the nylon bag.

[0027] In summary, the utility model provides a bag-making machine with a material collection function, including a residual waste outlet arranged at the front end of a fusing and forming platform and a waste collection device located below the residual waste outlet; the fusing and forming platform includes a support platform, a punching seat arranged above the support platform and moving longitudinally, and a clamping jaw seat moving laterally; wherein the punching seat and the clamping jaw seat are driven by a driving member (electric cylinder, air cylinder or oil cylinder) to work; the clamping jaw seat is provided with at least one set of clamping jaws, which are also driven by a driving member (electric cylinder, air cylinder or oil cylinder) to work. The moving clamping jaw seat first moves the bag body cut off in the previous process to the support platform through the clamping jaws, and then the punching seat descends, and uses the hot melt knife with a specific shape at its working end to trim the bag mouth and bag handle. Subsequently, the clamping jaw seat moves the trimmed bag body to the next process. After the placement is completed, the clamping jaw seat moves the next group of bag bodies to the support table again, and in the process of moving, pushes the residual waste left by the previous group into the residual waste discharge port. The utility model can collect and squeeze the residual waste falling to the residual waste discharge port through the relatively rotating collecting rollers, which can ensure the collection effect on the one hand and reduce the area occupied by the residual waste in the recycling bin on the other hand.
