[0030] Refer to Figure 1, an embodiment provided by the utility model: an efficient sealing and easy-to-tear film composite forming device, including a base 1. Four groups of symmetrically arranged support legs 11 are fixedly connected to the bottom surface of the base 1. The support legs 11 are used to support the base 1. A transmission component 2 and a trimming component 3 are arranged on the surface of the base 1. The transmission component 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 and the second bracket 22 are respectively fixedly connected to both sides of the surface of the base 1. Two groups of the first bracket 21 and the second bracket 22 are symmetrically arranged. A plurality of U-shaped frames 23 distributed in an array are fixedly connected to the side walls of the two groups of the first bracket 21. A feeding roller 24 is rotatably connected inside the U-shaped frame 23. The first bracket 21 is used to fix the U-shaped frame 23, so as to support both ends of the feeding roller 24 through the U-shaped frame 23. And the opening of the U-shaped frame 23 faces upward, which is convenient for placing the feeding roller 24, so that the feeding roller 24 can rotate inside the U-shaped frame 23. The feeding roller 24 is used for unwinding the raw material of the sealing and easy-to-tear film. A plurality of U-shaped frames 23 and feeding rollers 24 can place a plurality of raw materials of the sealing and easy-to-tear film. A winding roller 25 is rotatably connected between the two groups of the second bracket 22. A motor 26 is fixedly connected to the side wall of the second bracket 22. The second bracket 22 is used to support and fix the winding roller 25 and the motor 26. The output shaft of the motor 26 penetrates and is rotatably connected to the side wall of the second bracket 22. The output shaft of the motor 26 is fixedly connected to the end of the winding roller 25. The motor 26 is used to drive the winding roller 25 to rotate, so that the composite sealing and easy-to-tear film is wound around the surface of the winding roller 25.

[0031] Refer to Figure 1 , Figure 2 - Figure 3 , the trimming component 3 includes two groups of symmetrically arranged side plates 31. The tops of the two groups of side plates 31 are fixedly connected with a top plate 32. The two groups of side plates 31 are used to support the top plate 32. A chute 33 is opened on the surface of the top plate 32. The chute 33 is used for guiding and installing two groups of sliders 34, so that the sliders 34 can move horizontally inside the chute 33. Two groups of symmetrically arranged sliders 34 are slidably connected inside the chute 33. A bidirectional threaded rod 35 is threadedly connected between the two groups of sliders 34. The bidirectional threaded rod 35 penetrates and is rotatably connected to the side wall of the top plate 32. The bidirectional threaded rod 35 is used to drive the two groups of sliders 34 to move towards each other or away from each other, so as to adjust the distance between the two groups of sliders 34. A brake wheel 36 is fixedly connected to the end of the bidirectional threaded rod 35. The setting of the brake wheel 36 is convenient for the staff to manually rotate the bidirectional threaded rod 35.

[0032] Refer to Figure 1 , Figure 4, four sets of symmetrically arranged guide rods 37 are fixedly connected to the bottom surface of the slider 34. The outer part of the guide rod 37 is slidably connected with a downward pressure seat 38. The guide rod 37 is used to guide and position the downward pressure seat 38, so that the downward pressure seat 38 can move longitudinally along the guide rod 37. The downward pressure seat 38 is used to install the cutting knife 310. The downward pressure seat 38 is elastically connected to the bottom surface of the slider 34 through a return spring 39. The bottom surface of the downward pressure seat 38 is fixedly connected with a cutting knife 310. The return spring 39 provides a downward force for the downward pressure seat 38, so that the cutting knife 310 is closely attached to the surface of the passing sealing and easy-to-tear film. During the process of conveying the sealing and easy-to-tear film, the two sides of the sealing and easy-to-tear film are trimmed parallel. Connecting rods 311 are fixedly connected to the side walls of the two downward pressure seats 38. A hollow rod 312 is sleeved between the two connecting rods 311. The connecting rods 311 and the hollow rod 312 are used to lift the downward pressure seat 38, so as to facilitate placing the sealing and easy-to-tear film on the backing plate 313. And the two connecting rods 311 can slide inside the hollow rod 312 without affecting the movement of the two sliders 34. A backing plate 313 is fixedly connected between the two side plates 31. The backing plate 313 is used to support the bottom surface of the sealing and easy-to-tear film.

[0033] A hot pressing assembly 4 is arranged on the surface of the backing plate 313. The hot pressing assembly 4 includes a support plate 41. Two groups of support plates 41 are symmetrically arranged. Grooves 42 are formed on the side walls of the two groups of support plates 41. An installation seat 43 is slidably connected inside the groove 42. The support plate 41 and the groove 42 are used to install the installation seat 43. A hot pressing roller 44 is rotatably connected between the two installation seats 43. The two installation seats 43 are used to position the two ends of the hot pressing roller 44 and enable the hot pressing roller 44 to rotate. A resistance heating wire is arranged inside the hot pressing roller 44, which is used to heat the hot pressing roller 44, so as to achieve the hot pressing and compounding effect of the sealing and easy-to-tear film. A through hole is formed on the surface of the installation seat 43, and a positioning rod 45 is slidably connected in the through hole. Both ends of the positioning rod 45 are fixedly connected to the inner wall of the groove 42. The installation seat 43 is elastically connected to the inner wall of the groove 42 through a support spring 46. The positioning rod 45 is used to guide the installation seat 43, so that the installation seat 43 and the hot pressing roller 44 move stably. The support spring 46 increases the downward force of the installation seat 43 and presses the hot pressing roller 44 against the surface of the sealing and easy-to-tear film raw material.

[0034] Working principle: First, the staff place multiple sealing and easy-to-tear film raw materials on the feeding roller 24 inside the U-shaped frame 23 respectively. When the motor 26 is started, the receiving roller 25 starts to rotate. Under the traction of the transmission assembly 2, the sealing and easy-to-tear film raw material gradually unfolds from the feeding roller 24 and moves along the preset transmission path towards the receiving roller 25.

[0035] During the transmission of the raw material of the easy-tear sealing film, first, the raw material of the easy-tear sealing film enters the hot pressing assembly 4. Under the action of the supporting spring 46, the mounting seat 43 drives the hot pressing roller 44 to move downward and closely contact the surface of the raw material of the easy-tear sealing film. Since a resistance heating wire is arranged inside the hot pressing roller 44, the hot pressing roller 44 heats and presses the raw material of the easy-tear sealing film while rotating, achieving the hot pressing and compounding effect of the easy-tear sealing film.

[0036] Next, passing through the trimming assembly 3, the staff rotates the braking wheel 36 to drive the rotation of the bidirectional threaded rod 35, thereby adjusting the distance between the two groups of sliders 34, so that the cutting knife 310 can adapt to the raw material of the easy-tear sealing film with different widths. Under the action of the reset spring 39, the cutting knife 310 closely fits the surface of the raw material of the easy-tear sealing film, trimming both sides of the easy-tear sealing film to ensure that both sides of the easy-tear sealing film are parallel.

[0037] Finally, the compounded easy-tear sealing film is wound around the surface of the winding roller 25.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
