DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A split-type production equipment for plastic bags includes a plastic bag film blowing machine 1, a pressing shaping roller 2, a winding roller 12 and a workbench 9, a roller 8 is provided on the workbench 9, a slotting mechanism for slotting plastic bags is provided on the workbench 9, and the slotting mechanism includes a gantry 10 arranged on the workbench 9, a hydraulic cylinder 7 is provided on the gantry 10, a tool 13 is installed at the output end of the hydraulic cylinder 7, and a plurality of blades 14 are provided under the tool 13.

[0023] The side wall of the cutter 13 is provided with a cooling mechanism for reducing the temperature of the cutter 13, and the cooling mechanism includes a water storage box 15 fixedly connected to the side wall of the cutter 13, and the water storage box 15 is provided with a water inlet pipe 16 and a water outlet pipe connected to the interior thereof, and the water inlet pipe 16 and the water outlet pipe are sufficiently long hoses, and the water inlet pipe 16 is connected to an external water source.

[0024] In the utility model, a plurality of partitions are fixedly connected to the inner wall of the water storage box 15 , and the plurality of partitions are arranged at equal intervals to extend the retention time of the cooling water, so that the cooling water has a sufficiently long time to flow through the surface of the cutter 13 .

[0025] In the utility model, a first ink printer 3 is provided on the workbench 9, and a second ink printer 4 is also provided on the workbench 9. The first ink printer 3 and the second ink printer 4 can print icons on both sides of the plastic bag, so that the plastic bag does not need to be printed on an external printing device, thereby shortening the production time of the plastic bag.

[0026] In the utility model, a first air outlet pipe 5 is provided on the workbench 9, a second air outlet pipe 6 is connected to the side wall of the second ink printing machine 3 through an installation assembly, and a hot air blower 11 is provided on the side wall of the workbench 9. The first air outlet pipe 5, the second air outlet pipe 6 and the hot air blower 11 can quickly dry the ink.

[0027] In the utility model, the longitudinal section of the blade 14 is triangular, and a plurality of blades 14 are arranged at equal intervals, so that intermittent slots can be opened on the plastic bag.

[0028] When in use, after the plastic bag film blowing machine 1 and the pressing and shaping roller 2 are moved to the workbench 9, the first ink printer 3 and the second ink printer 4 continuously print the advancing plastic bag roll, so that the trademark pattern is printed on the surface of the plastic bag roll, so that the printing operation can also be carried out on the equipment, and the plastic bag does not need to be transferred to other transportation equipment for printing, which saves the transportation time and speeds up the production efficiency of the plastic bag;

[0029] Secondly, the output end of the hydraulic cylinder 7 is indirectly extended and retracted, and the blade 14 is inserted into the plastic bag during the downward pressing process of the cutter 13. It is worth noting that the blade 14 is not completely inserted into the plastic bag, but only the front end is inserted into the plastic bag, so that the plastic bag after cutting can have intermittent grooves, and the plastic bag is finally wound on the winding roller 12. During the process, the plastic bag can still be rolled after cutting. When using, it is only necessary to move and pull two adjacent plastic bags in opposite directions, and the two plastic bags will be split due to the pre-reserved grooves, so that the plastic bags can be rolled up, making it more convenient to store;

[0030] In addition, after long-term use, the temperature of the cutter 13 will continue to rise due to frictional heat. There will be cooling water flowing into the water storage box 15 on its surface from the water inlet pipe 16. The cooling water can take away a large amount of heat during the flow on the surface of the water storage box 15, so that the temperature of the cutter 13 is not too high, thereby preventing the overheated cutter 13 from curling the edge of the plastic bag when cutting the plastic bag, making it unsightly.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and practical concept of the present invention, which should be covered by the protection scope of the present invention.
