The rotation shaft of the rotating frame is coaxially arranged with the output shaft of the second rotary motor, and an operating space for clamping the shoe sole is formed between the front shoe sole pressing mold and the rear shoe sole pressing mold.

[0007] As an improvement of the present invention, a transmission rod is rotatably connected to the frame, and the rotating frame is indirectly rotatably connected to the frame by being fixedly connected to one end of the transmission rod. The end of the transmission rod away from the rotating frame is connected to the first rotary motor via a belt mechanism.

[0008] As an improvement of the present invention, the frame is further provided with a material placement assembly for placing film rolls and a film guiding assembly that cooperates with the material placement assembly.

[0009] As an improvement of the present invention, the material feeding assembly includes a support rod that is fixedly or rotatably connected to the frame and two baffles that are detachably and fixedly connected to the support rod.

[0010] As an improvement of the present invention, the film guiding assembly includes a fixed guide roller mechanism located directly above the material placement assembly and a movable guide roller mechanism located directly above the operating space;

[0011] The fixed guide roller mechanism includes a receiving guide roller rotatably connected to the frame;

[0012] The moving guide roller mechanism includes a lifting frame vertically slidably connected to the frame, an operating component for controlling the sliding position of the lifting frame, a discharge guide roller rotatably connected to the lifting frame, a pressing wheel located below the discharge guide roller, and a heating air gun located on the side of the discharge guide roller away from the material placement assembly. The pressing wheel is directly or indirectly rotatably connected to the lifting frame, and the heating air gun is mounted on the lifting frame.

[0013] As an improvement of the present invention, the operating component includes a lifting air rod and a pressure rod. The lower end of the lifting air rod is rotatably connected to the frame, and the upper end is rotatably connected to the lifting frame. One end of the pressure rod is rotatably connected to the frame, and the other end is provided with a handle. The pressure rod is slidably inserted into the lifting frame.

[0014] As an improvement of the present invention, the lifting frame is provided with a linkage mechanism, which includes an upper connecting rod rotatably connected to the lifting frame at one end, a lower connecting rod located below the upper connecting rod, a synchronizing rod fixedly connected to one end of the lower connecting rod and rotatably connected to the lifting frame, a rear connecting rod fixedly connected to the synchronizing rod at one end, a mounting base rotatably connected to both the upper and lower connecting rods, and a lower pressure air rod rotatably connected to the lifting frame at its upper end. The lower end of the lower pressure air rod is rotatably connected to the end of the rear connecting rod that is not connected to the synchronizing rod. The heating air gun includes an air nozzle that blows air toward the discharge guide roller and an air pipe connected to the air nozzle. The air pipe is vertically fixedly connected to the mounting base.

[0018] By adopting the above solution, the present invention has the following beneficial effects:

[0019] 1. By setting up a rotating component, the sole can be rotated manually during the film application process, resulting in relatively high production efficiency. Since the rotating component is equipped with a front and rear pressure film to hold the sole, and two rotary motors drive the front and rear pressure films to rotate respectively, it helps to avoid sole deformation and improve the yield rate.

[0020] 2. By setting up a film guide assembly, the film can be avoided from being contaminated by manual contact, and the film application efficiency can be further improved. Attached Figure Description

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-3 As shown, this embodiment provides a shoe sole laminating machine, including a frame 10. The frame 10 is provided with a rotating component 20, a material placement component 30 for placing film rolls, a film guiding component 40 that cooperates with the material placement component 30, and a control console 50 for controlling the working sequence of the rotating component 20. The control console 50 is a conventional control device and is not the focus of this embodiment, so it will not be described in detail here.

[0044] The rotating assembly 20 includes a rotating frame 21 rotatably connected to the frame 10, a first rotary motor 22 for driving the rotating frame 21 to rotate, a front sole mold 23 detachably fixedly connected to the rotating frame 21, a second rotary motor 24 mounted on the frame 10, a rotating disk 25 fixedly connected to the output shaft of the second rotary motor 24, a mounting plate 26 slidably connected to the rotating disk 25, an electromagnetic telescoping device 27 for driving the mounting plate 26 to slide, and a rear sole mold 28 detachably fixedly connected to the mounting plate 26. The rotation axis of the rotating frame 21 and the output shaft of the second rotary motor 24 are arranged horizontally and coaxially. At least two sliding rods are fixedly connected to the mounting plate 26 and slidably inserted into the rotating disk 25. Each sliding rod is parallel to the output shaft of the second rotary motor 24, thereby realizing the sliding connection between the mounting plate 26 and the rotating disk 25. It should be noted that the electromagnetic expansion joint 27 is preferably an electromagnetic expansion joint 27 with its own power supply and wireless communication module. This helps to avoid wire tangling. When the electromagnetic expansion valve 27 has wires (power lines or control lines, etc.), existing structures such as conductive slip ring assemblies can be used to avoid wire tangling. Alternatively, the wire tangling can be avoided by requiring the rotating disk 25 to rotate clockwise once and then reset counterclockwise. This will not be elaborated here.

[0045] The output shaft of the second rotary motor 24 faces the rotating frame 21, forming an operating space for clamping the sole between the front sole mold 23 and the rear sole mold 28. The shapes of the front sole mold 23 and the rear sole mold 28 on opposite sides need to be designed according to the specific shape of the sole to ensure better fit. The specific detachable connection structure of the front sole mold 23 and the rear sole mold 28 can be a conventional structure, such as using bolts for detachable fixing. In use, the sole is placed in the operating space and positioned corresponding to the front sole mold 23 and the rear sole mold 28. Then, the electromagnetic expansion joint 27 drives the mounting plate 26 to slide relative to the selector turntable 25, pushing the rear sole mold 28 to press the sole onto the front sole mold 23. Next, the two rotary motors rotate synchronously, causing the sole to rotate so that the film is attached to the side wall of the sole.

[0046] Preferably, in this embodiment, a horizontally arranged transmission rod 11 is rotatably connected to the frame 10. The rotating frame 21 is indirectly rotatably connected to the frame 10 by being fixedly connected to one end of the transmission rod 11. The end of the transmission rod 11 away from the rotating frame 21 is connected to the first rotary motor 22 through a conventional belt mechanism. This can prevent the pressure of the shoe sole rear mold 28 from being directly transmitted to the output shaft of the first rotary motor 22 when clamping the shoe sole, thereby improving transmission stability.

[0047] The feeding assembly 30 includes a support rod 31 fixedly or rotatably connected to the frame 10, and two baffles 32 detachably and fixedly connected to the support rod 31. The specific detachable connection structure between the baffles 32 and the support rod 31 is similar to that of a conventional winding and unwinding mechanism, and is not the focus of this embodiment, so it will not be described in detail here. When it is necessary to load or unload the film roll, one of the baffles 32 is removed, the support rod 31 is passed through the inner hole of the film roll, and then the removed baffle 32 is reinstalled, so that the film roll is located between the two baffles 32. In this way, the two baffles 32 can be used to limit the film roll and prevent the film roll from moving axially during use.

[0048] The film guiding assembly 40 includes a fixed guide roller mechanism located directly above the material feeding assembly 30 and a movable guide roller mechanism located directly above the operating space. The fixed guide roller mechanism includes a receiving guide roller 41 rotatably connected to the frame 10. The movable guide roller mechanism includes a lifting frame 42 vertically slidably connected to the frame 10, an operating component for controlling the sliding position of the lifting frame 42, a discharge guide roller 43 rotatably connected to the lifting frame 42, a pressure roller 44 located below the discharge guide roller 43, and a heating air gun 45 located on the side of the discharge guide roller away from the material feeding assembly 30. The pressure roller 44 is directly or indirectly rotatably connected to the lifting frame 42, and the heating air gun 45 is mounted on the lifting frame 42. The heating air gun 45 is a conventional high-temperature air gun, which can be purchased directly from the market. In addition, the material feeding assembly 30, the receiving guide roller 41, and the discharge guide roller 43 are arranged parallel to each other and located on the same vertical plane.

[0049] The operating components can be conventional parts, such as cylinders or lifting motors. In this embodiment, the operating components include a lifting air rod 46 and a pressure rod 47 arranged at an angle relative to the horizontal plane, both located on the same vertical plane or on mutually parallel vertical planes. The lower end (cylinder end) of the lifting air rod 46 is rotatably connected to the frame 10, and the upper end (telescopic rod end) is rotatably connected to the lifting frame 42. This allows the lifting air rod 46 to generate an upward elastic force, preventing the lifting frame 42 from naturally sliding down under gravity. One end of the pressure rod 47 is rotatably connected to the frame 10, and the other end is provided with a handle. The pressure rod 47 slides through the lifting frame 42, allowing the lifting frame 42 to be pressed down using the pressure rod 47, causing the lifting frame 42 to slide downward against the elastic force of the lifting cylinder 43. Since the pressure rod 47 can act as a lever, it has a labor-saving effect.

[0050] The pressure roller 44 can be directly rotatably connected to the lifting frame 42. Preferably, to facilitate adjustment of the position of the pressure roller 44 according to the shoe sole model, in this embodiment, an adjusting rod 48 is fixedly connected to the lifting frame 42 by adjusting bolts, and the pressure roller 44 is rotatably connected to the adjusting rod 48, thereby realizing an indirect rotatable connection between the pressure roller 44 and the lifting frame 42. In use, the position of the pressure roller 44 can be adjusted by loosening the adjusting screw to allow the adjusting rod 48 to swing.

[0051] The heating air gun 45 can be directly fixedly connected to the lifting frame 42. Preferably, in order to improve heating stability and the self-adaptive ability of the heating air gun 45, in this embodiment, the lifting frame 42 is provided with a linkage mechanism 60. The linkage mechanism 60 includes an upper connecting rod 61 rotatably connected to the lifting frame 42 at one end, a lower connecting rod 62 located below the upper connecting rod 61, a synchronizing rod 63 fixedly connected to one end of the lower connecting rod 62 and rotatably connected to the lifting frame 42, a rear connecting rod 64 fixedly connected to the synchronizing rod 63 at one end, and a rotatably connected to both the upper connecting rod 61 and the lower connecting rod. The mounting base 65 on 62 and the upper end (cylinder end) of the lower air rod 66 are rotatably connected to the lifting frame 42. The upper connecting rod 61 and the lower connecting rod 62 are located on the same vertical plane. The lifting frame 42, the mounting base 65, the upper connecting rod 61 and the lower connecting rod 62 together form a quadrilateral mechanism. The lower end (telescopic rod end) of the lower air rod 66 is rotatably connected to the end of the rear connecting rod 64 that is not connected to the synchronizing rod 63. The heating air gun 45 includes an air nozzle that blows air towards the discharge guide roller 43 and an air pipe connected to the air nozzle. The air pipe is vertically fixedly connected to the mounting base 65. In this way, when the film is stretched and presses against the heating air gun 45, the heating air gun 45 can move upward under the action of the push and pull force, and reset after the push and pull force disappears. At the same time, when debugging or when the heating air gun 45 is not needed, the mounting base 65 is pushed upward so that the rear connecting rod 64 and the downward pressure air rod 66 are on the same straight line, thereby temporarily fixing the heating air gun above the side of the discharge guide roller 43.

[0052] Preferably, a pressure roller 70 is provided above the receiving guide roller 41 and / or the discharging guide roller 43. In this embodiment, it is taken as an example that a pressure roller 70 is provided above both the receiving guide roller 41 and the discharging guide roller 43. Each pressure roller 70 is rotatably connected to a swing frame 71, that is, there are two swing frames 71. The two swing frames are respectively matched one-to-one with the two pressure rollers 70. The middle part of the swing frame 71 is rotatably connected to the frame 10 or the lifting frame 42. Whether it is rotatably connected to the frame 10 or the lifting frame 42 depends on whether it is matched with the receiving guide roller 41 or the discharging guide roller 43. The film-pressing guide roller 70 is located at one end of the corresponding swing frame 71. During use, the film-pressing guide roller 70 can descend under gravity to press the film onto the receiving guide roller 41 or the output guide roller 43. Before use, when threading the film, pressing the end of the swing frame 71 away from the corresponding film-pressing guide roller 70 will cause the corresponding film-pressing guide roller 70 to move upwards. The gap between the film-pressing guide roller and the receiving guide roller 41 or the output guide roller 43 is relatively large, facilitating film threading. Furthermore, guide members 72 are respectively provided beside the receiving guide roller 41 and the output guide roller 43. Both guide members 72 are located between the receiving guide roller 41 and the output guide roller 43, and are fixedly connected to the frame 10 or the lifting frame 42. Whether they are connected to the frame 10 or the lifting frame 42 depends on whether they are relatively closer to the receiving guide roller 41 or the output guide roller 43. The guide member 72 includes two guide rods arranged in parallel to each other, with a film-passing gap formed between the two guide rods. This can keep the separation position of the film from the receiving guide roller 41 and the position of the film entering the discharge guide roller 43 basically unchanged, and avoid the up-and-down movement of the moving guide roller mechanism from affecting the stability of film conveying.

[0053] Before use, the film roll is freely drawn out from the feeding assembly 30, first passing around the receiving guide roller 41 and exiting between the receiving guide roller 41 and the corresponding pressing guide roller 70. Then, it passes through the film-passing gaps of the two guide members 72 in sequence and wraps around the discharge guide roller 43, before being pulled to the bottom of the pressing roller 44. During use, pressing the pressure rod 47 causes the pressing roller 44 to press the film firmly onto the sole. At the same time, the sole rotates under the drive of two rotary motors, causing the film to adhere to the side wall of the sole, thus achieving film application. The sole should not be a rotating component, and its rotation should not be too fast to ensure that the pressing roller 44 can always press firmly against the sole.

[0054] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
