DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0021] Please refer to Figures 1 to 4 , the forming die for the non-PVC film soft bag large infusion automatic production line in this embodiment includes an upper die base 1 and a lower die base 2 that are correspondingly arranged up and down. Among them, a bearing seat 4 is fixedly installed at the top of the lower die base 2, an installation seat 3 is fixedly installed on the upper die base 1, a forming die-cutting part 5 is fixedly installed on the installation seat 3, and a heat-sealing line 6 for heat-sealing is arranged on the forming die-cutting part 5.

[0022] In this embodiment, a pressure block 7 is also fixedly installed at the bottom of the upper die base 1. The pressure block 7 is slidably connected to the bearing seat 4. Installation frames 8 are fixedly installed on both sides of the lower die base 2, and sliders 9 located below the pressure block 7 are slidably installed on the installation frames 8.

[0023] It should be noted that a convex strip 10 is integrally protruded at one end of the installation frame 8 facing the bearing seat 4, and one end of the slider 9 abuts against the convex strip 10 to limit the sliding limit position of the slider 9 facing the bearing seat 4.

[0024] In order to clean the lower end of the forming die-cutting part 5, a connecting block 13 is fixedly installed at the top of the slider 9 in this embodiment, and a cleaning plate 14 is slidably installed on one side surface of the connecting block 13 to clean the forming die-cutting part 5.

[0025] In this embodiment, a groove is provided on one side surface of the cleaning plate 14 facing the forming die-cutting part 5. A cleaning cloth 18 for cleaning the forming die-cutting part 5 is detachably and fixedly installed at the top of the cleaning plate 14. By sliding the cleaning plate 14 against the forming die-cutting part 5, the residues on the lower surface of the forming die-cutting part 5 can be cleaned.

[0026] It should be noted that the contact surfaces of the pressure block 7 and the slider 9 are both inclined surfaces and the inclination degrees correspond to each other, so that when the pressure block 7 presses downward against the slider 9, the slider 9 can slide relative to the installation frame 8.

[0027] In order to make the slider 9 slide back to its original position, a connecting plate 11 is fixedly installed at the end of the installation frame 8 in this embodiment. A return spring 12 is connected between the connecting plate 11 and the slider 9. One end of the return spring 12 is fixedly connected to the connecting plate 11, and the other end is fixedly connected to the side surface of the slider 9.

[0028] Since the upper die holder 1 moves downward when it moves, in this embodiment, a compression spring 15 is connected between the cleaning plate 14 and the slider 9. One end of the compression spring 15 is fixedly connected to the cleaning plate 14, and the other end is fixedly connected to the slider 9. By pushing the cleaning plate 14 upward through the compression spring 15, the cleaning plate 14 can be made to fit against the formed and die-cut part 5.

[0029] It should be noted that a dovetail groove 17 is formed on one side surface of the connecting block 13. A dovetail block 16 is fixedly installed at one end of the cleaning plate 14 connected to the connecting block 13. The dovetail block 16 is slidably connected to the dovetail groove 17. Through the design of the dovetail block 16, the sliding stability of the cleaning plate 14 relative to the connecting block 13 can be improved.

[0030] Preferably, one end of the dovetail groove 17 does not penetrate through the connecting block 13, so that the cleaning plate 14 under the elastic force of the compression spring 15 will not be separated from the connection with the connecting block 13.

[0031] The working principle of the above embodiment is as follows:

[0032] When the upper die holder 1 and the lower die holder 2 are controlled to be closed and heat-sealed for processing, the upper die holder 1 drives the fixedly connected pressing block 7 to move downward toward the lower die holder 2, and the pressing block 7 squeezes the slider 9 located on the mounting frame 8. At this time, the slider 9 slides toward the outside of the lower die holder 2 relative to the mounting frame 8. At this time, the connecting block 13 and the cleaning plate 14 connected to the top of the slider 9 slide outward. Since the compression spring 15 pushes the cleaning plate 14, the formed and die-cut part 5 installed on the upper die holder 1 can slide against the cleaning cloth 18 on the cleaning plate 14, so that the residues on the surface of the formed and die-cut part 5 after a single processing can be removed, effectively improving the finished product quality of continuous processing operations.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0034] Although embodiments of the present application have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
