[0002] Plastic bags are widely used in daily life and are an important packaging material. With the increase in plastic consumption, the production and processing technology of plastic bags has also been continuously developing. The traditional plastic bag production process usually involves multiple links, including raw material preparation, extrusion molding, cooling, winding and cutting. In this article, we need to discuss its cutting processing device in detail.

[0003] Reference is made to publication number CN213798369U, which proposes a cutting device for plastic bag processing. The main technical problem that existing cutting machines require a lot of manual operation and cannot automatically pull out the plastic bags is addressed. The problem is solved by placing an uncut plastic bag on a sleeve and then passing one end of the bag through the bottom of a pressing plate to keep the plastic bag flat. The automatic pulling mechanism can then be used to automatically pull out the plastic bag to facilitate subsequent cutting.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] See also Figures 1-4The utility model provides a plastic bag preparation and cutting processing device, including a processing trough table 1, a storage box 4 is provided at one end of the processing trough table 1, and the storage box 4 is used to store and place materials. A pressing roller 5 is fixedly connected to the surface of the processing trough table 1, and the pressing roller 5 is arranged on the side close to the storage box 4. A conveyor belt 2 is installed on the surface of the processing trough table 1, and the conveyor belt 2 is used to transmit the internal materials of the storage box 4. The surface of the conveyor belt 2 is overlapped with a cutting table 3, and the two ends of the cutting table 3 are abutted and connected with the surface of the conveyor belt 2. The cutting table 3 is a smooth design. A gathering roller 7 is also installed on the surface of the processing trough table 1, and observation and metering platforms 6 are installed on both sides of the discharge end of the processing trough table 1. The observation and metering platforms 6 and the gathering roller 7 are electrically connected. A lifting ribbon 8 is provided at the bottom of the gathering roller 7, and the lifting ribbon 8 is abutted and connected with the conveyor belt 2.

[0025] In this embodiment, referring to a cutting device for plastic bag processing proposed in the existing patent CN213798369U, the optimized structure of the device is a gathering roller 7, and a storage box 4 is added in the figure as a load-bearing support for the entire moving material of the processing trough table 1. Below we introduce the overall use of the processing trough table 1. It can be seen that the material stored in the storage box 4 is pressed by the pressing roller 5 and starts to move toward the installation position of the lifting ribbon 8 on the surface of the conveyor belt 2. After passing the cutting table 3, it is cut and processed. Then, the cut plastic bag will gradually move forward and enter the bottom of the gathering roller 7. The user reels the material by setting the lifting ribbon 8, and the setting of the observation metering table 6 is It is used to observe the material on the surface of the conveyor belt 2. We set up the observation and metering platform 6 in this way. The observation and metering platform 6 is set for a single start. The start condition is set to that the winding roller 7 leaves the surface of the conveyor belt 2. When the user needs to reel in the winding roller 7, the winding roller 7 is in a disengaged state, and the observation and metering platform 6 starts to count the start. After the winding roller 7 is reset, the observation and metering platform 6 starts to identify the material on the surface of the conveyor belt 2. When the material enters the observation line of the observation and metering platform 6, the observation and metering platform 6 starts to lift the ribbon 8, and the lifting ribbon 8 is lifted upward, thereby effectively converging the conveyor belt 2 during the rotation of the winding roller 7, thereby ensuring the automatic winding function of the winding roller 7.

[0026] Reference Figure 1-4 Support columns 9 are embedded and installed on both sides of the bundling roller 7. The support columns 9 are fixedly installed on the surface of the processing groove table 1. A snap-fitting slot 10 is provided on the top of the support column 9. The snap-fitting slot 10 is used to support the installation of the bundling roller 7. A pressure sensor 11 is installed at the bottom of the snap-fitting slot 10. The pressure sensor 11 is electrically connected to the observation and metering platform 6.

[0027] In this embodiment, through such a setting, the pressure sensor 11 will count a signal to start the observation and metering platform 6 after losing pressure. After the winding roller 7 disengages from the limit of the engaging slot 10, the pressure sensor 11 loses pressure. Therefore, it can be set in this way. The winding roller 7 itself is driven by a motor, connected to the same power supply as the conveyor belt 2 and has an independent switch. In this way, the observation of the matching observation and metering platform 6 can be started.

[0028] Reference Figure 1-4 A movable limiting groove 12 is provided inside the support column 9, and a pulling positioning block 14 is slidably connected inside the movable limiting groove 12. The bottom of the pulling positioning block 14 is fixedly connected to a pneumatic lifting rod 13, and a pulling bayonet 15 is installed inside the pulling positioning block 14. The pulling bayonet 15 is fixedly connected to the lifting ribbon 8.

[0029] In this embodiment, when the observation and metering platform 6 detects that the material passes through, the observation and metering platform 6 starts to control the pneumatic lifting rod 13, so that the pneumatic lifting rod 13 starts to lift. During the lifting process of the pneumatic lifting rod 13, the pulling positioning block 14 drives the pulling bayonet 15 to involve the lifting ribbon 8 to start lifting. During the lifting process of the lifting ribbon 8, the lifting ribbon 8 can drive the material to touch the rotating winding roller 7, so that the winding roller 7 can automatically reel in the material.

[0030] Reference Figure 1-4 A fan is also provided inside the gathering roller 7, and an adsorption card plate 16 is installed on the surface of the gathering roller 7. A suction card slot 17 is opened on the surface of the gathering roller 7, and the suction card slot 17 also runs through the interior of the adsorption card plate 16.

[0031] In this embodiment, through such an arrangement, when the lifting ribbon 8 lifts the material to the surface of the bundling roller 7, since the bundling roller 7 is rotating at this time, the material can be effectively adsorbed on the surface of the bundling roller 7, and the automatic bundling and winding of the material is completed through the rotation of the bundling roller 7.

[0032] Reference Figure 1-4 A contraction tension spring 18 is installed inside the pulling positioning block 14 , and a spring assembly positioning column 19 is installed inside the contraction tension spring 18 .

[0033] In this embodiment, by such a configuration, the device can effectively adjust the tightness of the lifting ribbon 8 during use. When the lifting ribbon 8 is pulled strongly, the tension spring 18 can automatically adjust it under the fixation of the spring group positioning column 19, thereby effectively ensuring that the lifting ribbon 8 will not break.

[0034] Reference Figure 1-4The lifting ribbon 8 is wound around the inside of the tightening tension spring 18 , and the tightening tension spring 18 is used to relax the tension of the lifting ribbon 8 .

[0035] In this embodiment, by such an arrangement, the use effect of the device is guaranteed and the problem of the device being easily broken during use is avoided.
