[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0026] In the first aspect, Figure 1 , Figure 2 As shown, an automatic film changing and film splicing mechanism includes: a first film supply roll 1 and a second film supply roll 2 for providing film strips, and a solid film assembly and a film splicing assembly 4 arranged at the discharge ends of the first film supply roll 1 and the second film supply roll 2, the solid film assembly is used to fix the film head or film tail of the first film supply roll 1 and the second film supply roll 2, so that the film splicing assembly 4 can dock with the first film supply roll 1 or the second film supply roll 2, grab and pull the film tail of the old film roll or the film head of the new film roll and dock with the film head of the new film roll or the film tail of the old film roll, heat and splice them together, wherein the heating element 9 can be set on any contact surface of the solid film assembly and the film splicing assembly 4, so that one end of the film strip grabbed by the film splicing assembly 4 docks with the solid film assembly while heating the overlapping splicing of the ends of the two film strips, and the film strips are bonded together after hot melt cooling.
[0027] Specifically, Figure 1 , Figure 2 As shown, the solid film assembly includes a first solid film assembly 31 and a second solid film assembly 32 which are correspondingly arranged at the discharge ends of the first film supply roll 1 and the second film supply roll 2, wherein the first solid film assembly 31 is connected to the first lifting assembly 5, and the first lifting assembly 5 is used to drive the first solid film assembly 31 to rise and fall to dock with the film connecting assembly 4 to connect the film head or film tail, and the second solid film assembly 32 is fixedly installed on the discharge side of the second film supply roll 2 through the support plate 6.
[0028] It should be noted that either the first film supply roll 1 or the second film supply roll 2 can be used as a new film roll or an old film roll for switching. The film connecting component 4 can be moved to the first solid film component 31 to connect with the film head or film tail on the first film supply roll 1, or can be moved to the second solid film component 32 to connect with the film head or film tail on the second film supply roll 2. When the first film supply roll 1 is a new film roll, the film head on the first film supply roll 1 is fixed on the first solid film component 31, and the film strip on the second film supply roll 2 passes between the film connecting component 4 and the second solid film component 32; when the second film supply roll 2 is a new film roll, the film head on the second film supply roll 2 is fixed on the second solid film component 32, and the film head on the first film supply roll 1 passes between the film connecting component 4 and the first solid film component 31.
[0029] In some embodiments, when the heating element 9 is arranged on the first solid film component 31 or the second solid film component 32, a film pressing component 42 pressed corresponding to the heating element 9 is provided on the film connecting component 4, and the film tail of the old film roll and the film head of the new film roll are pressed, heated and bonded together on the first solid film component 31 or the second film pressing component 42; when the heating element 9 is arranged on the film connecting component 4, a film pressing component 42 pressed corresponding to the heating element 9 is provided on the first solid film component 31 or the second solid film component 32, and each time the film connecting component 4 grabs the film tail of the old film roll or the film head of the new film roll on the first solid film component 31 and migrates it to the film tail of the old film roll or the film head of the new film roll on the second solid film component 32 for docking, the heating element 9 is heated to dock the film tail of the old film roll and the film head of the new film roll together by pressing and bonding.
[0030] In some embodiments, Figure 3 , Figure 4 As shown, when the heating element 9 is arranged on the first solid film component 31 or the second solid film component 32, the film connecting component 4 includes a connecting plate 41 and a first driving component 43 installed on the connecting plate 41, and the film pressing component 42 is connected to the driving end of the first driving component 43. The first driving component 43 is used to drive the film pressing component 42 to press the film tail of the old film roll and the film head of the new film roll against the heating surface of the heating element 9 to make the bonding between the adhesive films more firm.
[0031] Among them, the film pressing component 42 in this embodiment is preferably a flexible component, which can be a flexible material, such as elastically deformable materials such as rubber, silicone, nylon, high-density sponge, etc., or the film pressing component 42 can be elastically connected to the first driving component 43 through a spring, so that the film pressing component 42 can float in the opposite direction of the extrusion surface when pressed against the heating element 9, thereby eliminating the pressing strength between the film pressing component 42 and the heating element 9, making the surface of the film pressing component 42 and the heating element 9 elastically contact, and reasonably controlling the pressing force of the film strip, making the splicing of the film strip more stable and firm.
[0032] In addition, refer to Figure 1 , Figure 2 , Figure 5 As shown, the automatic film changing and film joining mechanism also includes a horizontal driving component 7 and a second lifting component 8 which are movably connected to the film joining component 4, the connecting plate 41 is connected to the second lifting component 8, and the second lifting component 8 is connected to the driving end of the horizontal driving component 7. The horizontal driving component 7 is used to drive the second lifting component 8 and the film joining component 4 to move horizontally and dock with the first solid film component 31 and the second solid film component 32 in sequence, and the second lifting component 8 is used to lift and drive the film joining component 4 so that the film joining component 4 moves to a height position matching the first solid film component 31 and the second solid film component 32.
[0033] Preferably, an adsorption component 10 for adsorbing and fixing the film is provided on the film connecting component 4, the first solid film component 31 and the second solid film component 32. The adsorption component 10 on the film connecting component 4 and the adsorption surfaces on the first solid film component 31 and the second solid film component 32 are parallel to each other and arranged relative to each other. The parallel arrangement includes vertical parallelism and horizontal parallelism or inclined parallelism between the adsorption surfaces, so that the adsorption surface of the film connecting component 4 is respectively connected to the adsorption surfaces of the first solid film component 31 and the second solid film component 32 to complete the connection between the head and tail ends of the film roll.
[0034] It should be noted that a plurality of adsorption holes are arranged in a matrix on the adsorption surface of each adsorption member 10 , so as to adsorb and fix the film tail of the old film roll or the film head of the new film roll on the surface.
[0035] In some embodiments, a cutting portion 11 and a second driving component 44 connected to the cutting portion 11 are provided on the film connecting component 4. The cutting portion 11 is used to cut the film tail of the old film roll and the film head of the new film roll that exceed the length of the adsorption of the adsorbent 10. When the new film roll is placed for the first time, the film head of the new film roll needs to be pre-placed on the adsorption component 10 of the first solid film component 31 or the second solid film component 32 for fixation. Since the position of manual film placement is not precise enough, the film head of the new film roll usually exceeds the adsorption area. In order to ensure the quality and aesthetics of the film in the equipment, the film head that exceeds the adsorption area needs to be cut off so that the splicing part of the film head and the film tail is neat. The excess part of the film tail of the old film roll is also cut off on the first solid film component 31 or the second solid film component 32 by the film connecting component 4 and then moved to the film head of the new film roll for bonding and interconnection.
[0036] In addition, the cutting portion 11 is preferably configured as an electric heating wire, which is arranged along the width direction of the film strip and parallel to one side of the film pressing component 42, and a cutting groove 33 matching the electric heating wire is provided on the solid film component. Correspondingly, the first solid film component 31 and the second solid film component 32 are both provided with a cutting groove 33 matching the electric heating wire. When the film connection component 4 and the first solid film component 31 or the second solid film component 32 are docked with the adsorption film head or film tail, the film tail or film head is cut off respectively. When cutting, the film pressing component 42 on the film connection component 4 is first docked and pressed with the film strip on the surface of the adsorbent 10 on the first solid film component 31 or the second solid film component 32, and then the second driving component 44 drives the electric heating wire to move into the cutting groove 33 to cut off the length of the film strip exceeding the cutting groove 33. The electric heating wire uses a hot stamping process to cut the film strip along its width, and the cutting efficiency is faster and the cutting is smoother. Of course, the present invention also includes a method of cutting the film strip by a cutter, wherein the cutter is drivingly connected to the second driving component 44 and corresponds to the cutting groove 33 to cut the excess film length beyond the cutting groove 33 .
[0037] It should be noted that the positions of the new film roll and the old film roll can be interchanged. For example, the positions of the first solid film component 31 and the second solid film component 32 relative to the first film supply roll 1 and the second film supply roll 2 can be interchanged. Therefore, the first solid film component 31 and the second solid film component 32 can both be used to fix the film head of the new film roll. Correspondingly, the first solid film component 31 and the second solid film component 32 can also be used to fix the film tail of the old film roll. Therefore, a cutting groove 33 corresponding to the cutting portion 11 can be respectively provided on both sides of the adsorbent 10 on the first solid film component 31 or the second solid film component 32, so as to be used for cutting the film head or the film tail, respectively.
[0038] In some embodiments, a detection element 12 is further provided on one width side of the first film supply roll 1 and the second film supply roll 2. The detection element 12 is used to detect the presence or absence of film strips on the film supply rolls. When it is detected that the thickness of the film roll is almost zero, the detection signal is fed back to the control system. The control system directly controls the film splicing component 4 to cooperate with the first film solidifying component 31 and the second film solidifying component 32 to complete the splicing of the film tail of the old film roll and the film head of the new film roll.
[0039] In addition, in order to prevent the membrane strips from interfering with the first solid membrane component 31 or the second solid membrane component 32 after being butted together, a support wheel is provided on the support plate 6 for fixing the second solid membrane component 32, and the support wheel guides the membrane strips to pass on the support wheel after being spliced.
[0040] In the second aspect, the utility model also proposes a film supply device, which includes at least two groups of the above-mentioned automatic film changing and film splicing mechanisms, and multiple groups of automatic film changing and film splicing mechanisms are arranged side by side. The film supply device also includes a film strip cache component 100 respectively arranged at the film strip output end of each automatic film changing and film splicing mechanism, and the film strip in the first film supply roll 1 or the second film supply roll 2 is passed through the film strip cache component 100 and connected to the film strip processing device.
[0041] It should be noted that the output sections of the automatic film changing and film connecting mechanisms arranged side by side can output in the same direction or in the opposite direction. When outputting in the opposite direction, the film strip buffer component 100 is also symmetrically arranged in the opposite direction. According to different output directions, the adsorption surfaces between the film connecting component 4 and the first solid film component 31 and the second solid film component 32 can be adjusted arbitrarily. Optionally, the adsorption surfaces of the three are all in a vertically parallel state, or the adsorption surfaces of the three are all in a horizontally parallel state.
[0042] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope.
