Between the tops of the two vertical plates, two guide rails located on the front and back sides are fixedly installed. Two guide grooves are respectively opened inside the two guide rails. Between the middle parts of the tops of the two vertical plates, a threaded rod is rotatably connected through a bearing. On the outer wall of the top of one of the vertical plates, a first motor is fixedly installed. The output end of the first motor is fixedly connected to the threaded rod. An activity frame is sleeved on the outer side of the threaded rod in a threaded manner. Inside the upper end of the activity frame, a unwind roller is installed through a bearing.

On the inner walls of the front and back sides of the bottom of the activity frame, two turntables are respectively installed through bearings. The front turntable is fixedly connected to the output end of the second motor. Between the two turntables, two tension rollers are symmetrically fixed.

[0008] Preferably, the two groups of directional rotation components and the two groups of guide rails are both symmetrically arranged front and back. On the bottom end surface of the top of the guide rail, a toothed structure equal in length to it is provided.

[0009] Preferably, the end of the unwind roller passes through the guide groove and extends to the inside of the directional rotation component. On the outer walls of the left and right ends of the unwind roller, toothed structures are both provided.

[0010] Preferably, the directional rotation component includes a gear sleeve, a limiting groove, a dial and a spring. The gear sleeve is sleeved on the outer side of the end of the unwind roller through a bearing. On the inner wall of the gear sleeve, a plurality of the limiting grooves are annularly opened.

[0026] The following described embodiments are only a part of the embodiments of the present utility model and do not represent all embodiments consistent with the present utility model. Now, in conjunction with the drawings, the exemplary embodiments are described as follows:

[0027] As Figure 1-6 As shown in one of the figures, the hot melt film one - time forming and laminating device of the present utility model includes a bottom plate 1. Above the left and right ends of the bottom plate 1, two vertical plates 2 are respectively fixed. Between the tops of the two vertical plates 2, two guide rails 12 located on the front and rear sides are fixedly installed. Inside the two guide rails 12, two guide grooves 13 are respectively opened. Between the middle parts of the tops of the two vertical plates 2, a threaded rod 4 is rotatably connected through a bearing. On the outer wall of the top of one of the vertical plates 2 at the right end of the bottom plate 1, a first motor 3 is fixedly installed. The output end of the first motor 3 is fixedly connected to the threaded rod 4. An activity frame 5 is thread - sleeved on the outer side of the threaded rod 4. Inside the upper end of the activity frame 5, an unwinding roller 6 is installed through a bearing. On the outer sides of the front and rear ends of the unwinding roller 6, two groups of directional rotation assemblies 7 are respectively provided. The two groups of directional rotation assemblies 7 are respectively connected to the two guide grooves 13. On the front - end outer wall of the bottom of the activity frame 5, a second motor 9 is fixedly installed. On the inner walls of the front and rear sides of the bottom of the activity frame 5, two turntables 10 are respectively installed through bearings. The front turntable 10 is fixedly connected to the output end of the second motor 9. Between the two turntables 10, two tensioning rollers 11 are symmetrically fixed.

[0028] As a preferred implementation manner, on the basis of the above - mentioned structure, further, the two groups of directional rotation assemblies 7 and the two groups of guide rails 12 are both symmetrically arranged front - to - back. On the bottom end face of the top of the guide rail 12, a toothed structure equal to its length is provided.

[0029] As a preferred implementation manner, on the basis of the above - mentioned structure, further, the end of the unwinding roller 6 passes through the guide groove 13 and extends to the inside of the directional rotation assembly 7. On the outer walls of the left and right ends of the unwinding roller 6, toothed structures are provided.

[0030] In this embodiment, by setting the guide rail 12 and the guide groove 13, the stability of the activity frame 5 and the unwinding roller 6 during the horizontal movement can be improved, and by using the toothed structure on the bottom end face of the bottom of the guide rail 12, the rotational operation of the directional rotation assembly 7 is facilitated.

[0031] As a preferred embodiment, on the basis of the above structure, further, the directional rotation assembly 7 includes a gear sleeve 71, a limiting groove 72, a dial 73 and a spring 74. The gear sleeve 71 is sleeved on the outer side of the end of the unwinding roller 6 by means of a bearing. A plurality of limiting grooves 72 are annularly formed on the inner wall of the gear sleeve 71. A dial 73 is rotatably installed inside the limiting groove 72. A spring 74 is fixedly connected between the side of the dial 73 close to the limiting groove 72.

[0032] In this embodiment, the formation of the limiting groove 72 facilitates restricting the rotation direction and amplitude of the dial 73, and through the arrangement of the spring 74, it is convenient to support the dial 73.

[0033] As a preferred embodiment, on the basis of the above structure, further, the gear sleeve 71 meshes with the toothed structure on the bottom end surface of the top of the guide rail 12, and the bottom end of the dial 73 meshes with the toothed structure on the outer wall of the end of the unwinding roller 6.

[0034] In this embodiment, when controlling the movable frame 5 and the unwinding roller 6 to move leftward, by using the toothed structure on the bottom end surface of the top of the guide rail 12, the gear sleeve 71 can be rotated clockwise. At this time, the unwinding roller 6 can be driven to rotate synchronously by using the dial 73, which is convenient for quantitatively discharging the hot melt film.

[0035] As a preferred embodiment, on the basis of the above structure, further, a pressing and defoaming assembly 8 is installed on the left side of the bottom of the movable frame 5. The pressing and defoaming assembly 8 includes a connecting plate 81, a first electric push rod 82 and a pressing roller 83. The two connecting plates 81 are respectively fixedly connected to the left side walls of the front and rear ends of the bottom of the movable frame 5. The first electric push rods 82 are fixedly installed on the left sides of the two connecting plates 81. A pressing roller 83 is installed between the telescopic ends of the two first electric push rods 82 by means of a bearing.

[0036] In this embodiment, when controlling the movable frame 5 and the unwinding roller 6 to move leftward for discharging and laminating the hot melt film, the pressing roller 83 can be controlled to move downward by the first electric push rod 82, which is convenient for pressing and defoaming the hot melt film.

[0037] As a preferred embodiment, on the basis of the above structure, further, second electric push rods 14 are fixedly installed through the bottoms of the two vertical plates 2. The telescopic ends of the second electric push rods 14 are fixedly connected with a push plate 15.

[0038] In this embodiment, the push plate 15 can be controlled to move by the second electric push rod 14, which is convenient for clamping and positioning the product to be laminated, and ensures the stable and smooth progress of the hot melt film laminating process.

[0039] The working principle of the present utility model is as follows:

[0040] During use, first place the product to be film-coated above the middle of the bottom plate 1. Subsequently, use the second electric push rod 14 fixedly installed at the bottom of the vertical plate 2 to control the two push plates 15 to slide and approach each other until the product is positioned. Then, pull out one end of the hot melt film installed outside the unwind roller 6 and attach it to the outer surface of the top right end of the product. At the same time, start the first electric push rod 82 to control the pressing roller 83 to move vertically downward, so that the pressing roller 83 presses the hot melt film tightly on the product surface. And during the film-coating process, the pressing roller 83 can play a role in removing bubbles, ensuring that the hot melt film fits smoothly and tightly.

[0041] Subsequently, start the first motor 3 to control the rotation of the threaded rod 4, and control the movable frame 5 to drive the unwind roller 6 and the orientation rotation assembly 7 to move steadily to the left along the guide groove 13. At this time, using the toothed structure provided on the bottom end surface of the top of the guide rail 12, it can control the leftward movement of the gear sleeve 71 while rotating clockwise, as Figure 3 and Figure 4 shown in the figure. The clockwise-rotating gear sleeve 71 can push the toothed structure on the outer wall of the end of the unwind roller 6 through the dial 73, and can drive the unwind roller 6 to rotate clockwise while moving leftward, so as to facilitate the release of the hot melt film installed outside it and facilitate fitting. When the fitting is completed and the movable frame 5 is controlled to move rightward and reset, at this time the gear sleeve 71 rotates counterclockwise. Therefore, the dial 73 is pressed and rotates towards the limiting groove 72 and disengages from the toothed structure at the end of the unwind roller 6. Therefore, when the movable frame 5 moves rightward and resets, the unwind roller 6 is in a stationary state, and the hot melt film will no longer be released, which can realize the quantitative release of the hot melt film and facilitate fitting processing and management.

[0042] At the same time, during the process of fitting the hot melt film, in order to avoid wrinkles, when the hot melt film is relatively loose, the second motor 9 can be started to control the turntable 10 to drive the two tension rollers 11 to rotate slowly synchronously. The two tension rollers 11 can simultaneously extrude different positions of the hot melt film from two opposite directions, facilitating the re-tensioning of the loose hot melt film and facilitating fitting.

[0043] The above is only the preferred specific embodiment of the present invention, and it is not intended to limit the protection scope of the present invention; all equivalent changes, modifications, substitutions and variations made by those skilled in the art in the technical field according to the concept of the present invention on the basis of the existing technology through logical analysis, reasoning or limited experiments shall fall within the protection scope determined by the claims.
