DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the Figs. 1-6 The present application will be further described in detail.

[0026] Reference Figs. 1-6 An automatic film covering device, comprising a mold 1 driven by hydraulic pressure to move up and down, a horizontal driving mechanism installed on the upper surface of the lower mold of the mold 1 for driving the film covering mechanism to move along the width direction of the mold 1, and the film covering mechanism for covering the product in the mold cavity of the mold 1.

[0027] As Figs. 1-4 shown, the horizontal driving mechanism comprises a U-shaped mounting frame 2 fixed on the upper surface of the lower mold of the mold 1, limiting seats 21 fixedly installed on the surfaces of both ends of the U-shaped mounting frame 2, which can determine the installation position of the U-shaped mounting frame 2 and install parts through the limiting seats 21, in order to install the horizontal threaded rod 22 and the guide rod 23, the horizontal threaded rod 22 is installed on the inner walls of the two limiting seats 21 through bearings, further, two mirror image distributed guide rods 23 are fixedly connected to the inner walls of the two limiting seats 21 on both sides of the horizontal threaded rod 22, in order to drive the horizontal threaded rod 22 to rotate, a first forward and reverse motor 24 for driving the horizontal threaded rod 22 to rotate is fixedly installed on one side surface of one of the limiting seats 21, the horizontal threaded rod 22 and the guide rod 23 can be installed through the two limiting seats 21, and the horizontal threaded rod 22 is driven by the first forward and reverse motor 24, so that when the parts installed on the horizontal threaded rod 22 move, they are circumferentially limited by the guide rods 23.

[0028] In order to drive the film covering mechanism to move, a sliding seat 25 connected with the film covering mechanism is arranged inside the U-shaped mounting frame 2. In order to make the sliding seat 25 move only along the length direction of the U-shaped mounting frame 2, the sliding seat 25 is threadedly connected with the outer surface of the transverse threaded rod 22 and movably sleeved with the outer surface of the guide rod 23. The sliding seat 25 can be driven to move in the U-shaped mounting frame 2 by rotating the transverse threaded rod 22. In order to guide the film covering mechanism during movement, guide grooves 26 for guiding the film covering mechanism during movement are arranged on the inner walls of both sides of the U-shaped mounting frame 2. The two ends of the guide grooves 26 are in the shape of downward arcs. The state of the film covering mechanism can be controlled by the shape characteristics of the guide grooves 26.

[0029] By arranging the transverse driving mechanism, the first reversible motor 24 can drive the transverse threaded rod 22 to move, so that the film covering mechanism moves along the length direction of the U-shaped mounting frame 2, the film covering of the product is realized, the operation is simple and fast, the film covering efficiency is high, and the structure is simple and compact, facilitating the replacement and maintenance of parts in the later period.

[0030] As shown in Figs. 1-6 The film covering mechanism comprises a vertical mounting frame 3 arranged inside the U-shaped mounting frame 2. The lower end inner wall of the vertical mounting frame 3 is rotatably sleeved with two symmetrically distributed mounting shafts 31. The mounting position of the mounting shafts 31 can be determined, and the connection between the U-shaped mounting frame 2 and the vertical mounting frame 3 is limited. In order to make the vertical mounting frame 3 move smoothly in the U-shaped mounting frame 2, the outer surface of one of the mounting shafts 31 is movably sleeved with the upper end inner wall of the sliding seat 25. The outer surfaces of the two ends of the two mounting shafts 31 are fixedly sleeved with rollers 32 which roll along the inner wall of the guide groove 26. The mounting shafts 31 can be used to mount the rollers 32, and the connection relationship between the rollers 32 and the guide groove 26 is determined. The rollers 32 roll in the guide groove 26 to drive the vertical mounting frame 3 to move.

[0031] In order to guide the bearing seat 34, guide sliding grooves 33 are arranged on the inner walls of both sides of the upper end of the vertical mounting frame 3. The inner walls of the two guide sliding grooves 33 are provided with bearing seats 34 which are slidably connected with the two side edges of the guide sliding grooves 33. The mounting position of the bearing seat 34 can be determined, and the bearing seat 34 is guided by the guide sliding groove 33. In order to make the lifting seat 35 rise or fall, the lifting seat 35 is rotatably connected with the connecting rod between the two bearing seats 34, and the screw sleeve 36 is fixedly sleeved with the inner wall of the lifting seat 35. The two bearing seats 34 are connected by the connecting rod, and the lifting seat 35 is mounted between the two bearing seats 34. The lifting seat 35 is driven to move by the movement of the bearing seat 34.

[0032] In order to drive the vertical threaded rod 38, a second forward and reverse motor 37 is installed in the middle of the vertical mounting frame 3, and a vertical threaded rod 38 threaded with the screw sleeve 36 is fixedly connected to the main shaft end of the second forward and reverse motor 37. In order to install the film roller 310, a support rod 39 for installing the film roller 310 is fixedly sleeved on the outer surface of one end of the connecting rod. The vertical threaded rod 38 can be driven to rotate by the second forward and reverse motor 37, and the lifting seat 35 is lifted or lowered by the threaded cooperation between the vertical threaded rod 38 and the screw sleeve 36 when the vertical threaded rod 38 rotates.

[0033] By setting the film covering mechanism, the position of the lifting seat 35 can be adjusted by the cooperation of the second forward and reverse motor 37 and the vertical threaded rod 38, and the height of the film roller 310 is adjusted, so that the film covering device can cover different sizes of products, and the application range of the film covering device is expanded.

[0034] Working principle: when covering the product, first put the product to be covered into the mold cavity of the mold 1, adjust the height of the film roller 310 according to the size of the product, control the second forward and reverse motor 37 to start, and drive the lifting seat 35 to rise or fall by the rotation of the vertical threaded rod 38. When the lifting seat 35 moves, the bearing seat 34 slides in the guide sliding groove 33 to prevent the lifting seat 35 from rotating with the vertical threaded rod 38.

[0035] After adjusting the position of the film roller 310, control the first forward and reverse motor 24 to start, drive the horizontal threaded rod 22 to rotate, because the two guide rods 23 limit the circumferential direction of the sliding seat 25, and the sliding seat 25 and the horizontal threaded rod 22 are in threaded cooperation, so that the sliding seat 25 can only move along the direction of the guide rod 23, and drive the film covering mechanism to move along the length direction of the U-shaped mounting frame 2. Because of the shape of the guide groove 26 and the cooperation of the roller 32 and the guide groove 26, the vertical mounting frame 3 transitions from the state of tilting to one side to the vertical state and finally to the state of tilting to the other side, and the product is quickly and comprehensively covered.

[0036] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
