Description

Technical Field

[0001] This utility model relates to the field of film turning devices, and in particular to an automatic film turning device. Background Technology

[0002] In the film production process, mixing and plasticizing are crucial initial steps. To ensure that pigments, fillers, plasticizers, and other additives are evenly dispersed in the base resin and to remove air bubbles before subsequent calendering or casting, the turning and mixing of materials is essential. Whether it is manual turning on an open mill or turning materials during shutdown of an internal mixer, it heavily relies on manual experience and operating rhythm. This is not only labor-intensive but also interrupts the continuous mixing process, prolonging the entire mixing cycle. In the prior art, there are still problems such as partial overlap and adhesion during the film turning process. For example, CN208324152U discloses an automatic turning frame, including a support frame. A rotating shaft is installed on one side of the support frame, and a V-shaped turning plate is rotatably installed on the rotating shaft. Two sets of first cylinders are rotatably installed on the support frame below the V-shaped turning plate. The piston rods of the two sets of first cylinders are rotatably connected to the outer wall of the V-shaped turning plate away from the rotating shaft. Two inclined sliding rods are welded to both ends of the support frame along its width direction. Movable collars are movably installed on both sliding rods. A support rod is welded between the lower sides of the two movable collars. A second cylinder is installed in the middle of the support frame along the inclined direction of the sliding rods. Although the existing technology can flip components such as pipes into the movable flipping plate via the V-shaped flipping plate, and the movable flipping plate moves along the inclined slide bar to the arc-shaped slide plate to achieve sliding flipping, the existing technology still cannot solve the problems of partial overlap, adhesion, and inability to continuously flip materials during the film flipping process. Utility Model Content

[0003] To solve the above-mentioned technical problems, the automatic film turning device provided by this utility model improves the first conveyor belt mechanism and the second conveyor belt mechanism which are arranged vertically and in opposite directions, and sets a turning gap with a height equal to the thickness of the film, so that the film can automatically and continuously complete the transition and turning from one layer to another during the conveying process.

[0004] This utility model is achieved using the following technical solution: An automatic film turning device includes a frame, a first conveyor belt mechanism, and a second conveyor belt mechanism. The first conveyor belt mechanism is inclined to the frame, and the second conveyor belt mechanism is positioned above the first conveyor belt mechanism. A turning gap is provided between the upwardly inclined end of the first conveyor belt mechanism and the second conveyor belt mechanism. The height of the turning gap is equal to the thickness of the film. When the film is conveyed to the turning gap by the first conveyor belt mechanism, the surface of the conveyor belt of the second conveyor belt mechanism adheres to the surface of the film and has an adhesive effect. The conveying direction of the first conveyor belt mechanism is opposite to the conveying direction of the second conveyor belt mechanism so that the film is turned onto the second conveyor belt mechanism.

[0005] As an optional solution of this utility model, it also includes a movable support rod and a telescopic adjustment component. The movable support rod is fixedly installed on both sides of the frame and is rotatably connected to the first conveyor belt mechanism. One end of the telescopic adjustment component is connected to the frame, and the other end is connected to the material turning gap of the first conveyor belt mechanism. When the telescopic adjustment component extends or retracts, the height of the material turning gap changes.

[0006] As an optional solution of this utility model, the surface of the conveyor belt is provided with an uneven texture to increase the static friction between it and the surface of the film; when the film is transferred from the first conveyor belt mechanism to the second conveyor belt mechanism, the surface static friction of the conveyor belt of the second conveyor belt mechanism is greater than that of the conveyor belt of the first conveyor belt mechanism.

[0007] As an optional solution of this utility model, it also includes a heat dissipation component connected to the frame. The heat dissipation component is disposed above the first conveyor belt mechanism. The heat dissipation component includes a heat dissipation support frame, a heat dissipation fan, and a heat dissipation fan protective net. The heat dissipation support frame is connected to the vertical rod of the frame. The fan blades of the heat dissipation fan face the feeding conveyor belt of the first conveyor belt mechanism, and a heat dissipation fan protective net is disposed below the heat dissipation fan.

[0008] As an optional solution of this utility model, both the first conveyor belt mechanism and the second conveyor belt mechanism include a conveyor frame, a drive motor, a drive roller, an auxiliary support roller, and a conveyor belt. One end of the conveyor frame is provided with a drive motor, which is connected to the drive roller. The other end of the conveyor frame is provided with a driven auxiliary support roller, and a conveyor belt is provided between the drive roller and the auxiliary support roller.

[0009] As an optional solution of this utility model, both the first conveyor belt mechanism and the second conveyor belt mechanism include a tension adjusting component for adjusting the tension of the conveyor belt, and the tension adjusting component is disposed at the bottom of the conveyor frame.

[0010] As an optional embodiment of this utility model, the tension adjustment assembly includes a support bracket, a tension adjustment rod, and a tension sensing roller. The support bracket is disposed on the side of the conveyor frame; the tension adjustment rod is disposed on the support bracket, the telescopic end of the tension adjustment rod is connected to the end of the tension sensing roller, and the outer side of the tension sensing roller is rotatably connected to the return section of the conveyor belt.

[0011] As an optional solution of this utility model, the tension adjusting rod is a pneumatic telescopic adjusting rod, which is symmetrically arranged on both sides of the support bracket.

[0012] As an optional solution of this utility model, it also includes a controller and a solenoid valve mounted on the frame; the controller is electrically connected to the solenoid valve and the tension sensing roller, and the output end of the solenoid valve is connected to the air path of the input end of the pneumatic telescopic adjustment rod.

[0013] As an optional solution of this utility model, it also includes an auxiliary conveyor belt mechanism for cooperating with the first conveyor belt mechanism and the second conveyor belt mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This application employs a first and second conveyor belt mechanism arranged vertically and in opposite directions, with a turning gap equal in height to the film thickness. When the film is conveyed to the turning gap by the first conveyor belt mechanism, the surface of the second conveyor belt adheres to the film surface with adhesiveness. The conveying directions of the first and second conveyor belt mechanisms are opposite, causing the film to be turned onto the second conveyor belt mechanism, thus achieving film turning. This ensures smooth film movement and prevents jamming, wrinkling, or tearing during the turning process. It achieves automatic receiving, turning, and conveying of the film between the two conveyor layers, improving production efficiency. The improved telescopic adjustment component in this invention allows the height of the turning gap to increase or decrease as it extends or retracts, accommodating the turning needs of films of different thicknesses.

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0018] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0021] In one embodiment of this utility model, such as Figures 1 to 3As shown in the figure, the automatic film turning device provided in this embodiment includes a frame 1, a first conveyor belt mechanism 2, and a second conveyor belt mechanism 3. The first conveyor belt mechanism 2 is inclined to the frame 1, and the second conveyor belt mechanism 3 is disposed above the first conveyor belt mechanism 2. A turning gap 4 is provided between the upwardly inclined end of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3. The height of the turning gap 4 is equal to the thickness of the film. When the film is conveyed to the turning gap 4 by the first conveyor belt mechanism 2, the surface of the conveyor belt 16 of the second conveyor belt mechanism 3 is in contact with the surface of the film and has an adhesive effect. The conveying direction of the first conveyor belt mechanism 2 is opposite to the conveying direction of the second conveyor belt mechanism 3 so that the film is turned to the second conveyor belt mechanism 3.

[0022] In this embodiment, when the film to be flipped is conveyed upwards at an angle from the first conveyor belt mechanism 2 to the flipping gap 4, since the height of the flipping gap 4 is equal to the thickness of the film, the second conveyor belt mechanism 3, running in the opposite direction, comes into contact with the top surface of the film, and the two have a certain degree of adhesion, guiding the film to the surface of the second conveyor belt mechanism 3. At this time, the film continues to be conveyed along the second conveyor belt mechanism 3 until the entire film is flipped. In this embodiment, the film can also be conveyed from the second conveyor belt mechanism 3 to the flipping gap 4. Since the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 run in opposite directions, the film is conveyed downwards to the first conveyor belt mechanism 2, completing the flipping.

[0023] In another embodiment of this utility model, such as Figures 2 to 3 As shown, the device also includes a movable support rod 10 and a telescopic adjustment component 11. The movable support rod 10 is fixedly mounted on both sides of the frame 1 and is rotatably connected to the first conveyor belt mechanism 2. One end of the telescopic adjustment component 11 is connected to the frame 1, and the other end is connected to the material turning gap 4 of the first conveyor belt mechanism 2. When the telescopic adjustment component 11 extends or retracts, the height of the material turning gap 4 changes. Preferably, the movable support rod 10 is hinged to the side of the first conveyor belt mechanism 2. This arrangement allows the movable support rod 10 to act as a flexible fulcrum for the first conveyor belt mechanism 2, making the height adjustment of the material turning gap 4 smoother.

[0024] like Figure 5 As shown, the telescopic adjustment component 11 is one of a pneumatic telescopic rod, a hydraulic telescopic rod, or an electric push rod; all three can effectively control the telescopic stroke. In this embodiment, when the telescopic adjustment component 11 extends or retracts, the height of the flipping gap 4 increases or decreases, which can adapt to the flipping requirements of films of different thicknesses.

[0025] In another embodiment of this utility model, such as Figures 1 to 3As shown, both the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 include a conveyor frame 12, a drive motor 13, a drive roller 14, an auxiliary support roller 15, and a conveyor belt 16. One end of the conveyor frame 12 is provided with a drive motor 13, which is connected to the drive roller 14. The other end of the conveyor frame 12 is provided with a driven auxiliary support roller 15. The conveyor belt 16 is arranged between the drive roller 14 and the auxiliary support roller 15.

[0026] Preferably, the drive motor 13 is a servo motor. When the servo motor drives the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 to transport the film, it can better match and adjust the speed. The conveying speeds of the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 are matched to avoid film deviation caused by excessive speed.

[0027] Preferably, the surface of the conveyor belt 16 is provided with an uneven texture, which increases the static friction between it and the surface of the film; preferably, the conveyor belt 16 is a PVC grass-textured conveyor belt, and the surface of the PVC grass-textured conveyor belt is provided with an uneven texture, which meets the static friction requirements of film turning.

[0028] Preferably, when the film is transferred from the first conveyor belt mechanism 2 to the second conveyor belt mechanism 3, the surface static friction of the conveyor belt 16 of the second conveyor belt mechanism 3 is greater than the surface static friction of the conveyor belt 16 of the first conveyor belt mechanism 2.

[0029] In another embodiment of this utility model, such as Figures 2 to 3 As shown, both the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3 include a tension adjustment component 17 for adjusting the tension of the conveyor belt 16, and the tension adjustment component 17 is located at the bottom of the conveyor frame 12.

[0030] Preferably, the tension adjustment assembly 17 includes a support bracket 171, a tension adjustment rod 172, and a tension sensing roller 173. The support bracket 171 is disposed on the side of the conveyor frame 12. The tension adjustment rod 172 is disposed on the support bracket 171. The telescopic end of the tension adjustment rod 172 is connected to the end of the tension sensing roller 173. The outer side of the tension sensing roller 173 is rotatably connected to the return section of the conveyor belt 16.

[0031] Preferably, the support bracket 171 of the tension adjustment assembly 17 further includes a stabilizing groove 174, which is disposed on both sides of the tension adjustment rod 172 to prevent the tension adjustment rod 172 from shifting position during the extension and retraction process, thereby improving the stability of tension adjustment.

[0032] In this embodiment, a tension adjustment component 17 is provided to further improve the ability to turn over thicker films. When thicker films are transported by the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3, their own weight can easily cause the conveyor belt 16 to dent. When passing through the turning gap 4, poor contact can easily occur. The tension adjustment component 17 can adapt to the tension changes during the transmission process, adjust the flatness of the conveyor belt 16, and ensure the stability of film turning.

[0033] In another embodiment of this utility model, such as Figures 1 to 3 As shown, the tension adjusting rod 172 is a pneumatic telescopic adjusting rod, which is symmetrically arranged on both sides of the support bracket. The device also includes a controller 18 and a solenoid valve 19 mounted on the frame 1; the controller 18 is electrically connected to the solenoid valve 19 and the tension sensing roller 173, and the output end of the solenoid valve 19 is connected to the air path of the input end of the pneumatic telescopic adjusting rod. Preferably, the solenoid valve 19 is a two-position five-way solenoid valve, which can more conveniently adjust the telescopic adjustment of the pneumatic telescopic adjusting rod; the input end of the solenoid valve 19 is connected to an external air source; and the output end of the solenoid valve 19 is connected to each symmetrically arranged pneumatic telescopic rod. In this embodiment, the solenoid valve 19 cooperates with the pneumatic telescopic rod to make the tension adjustment more flexible and stable.

[0034] In another embodiment of this utility model, such as Figure 4 As shown, the device further includes a heat dissipation component 6 connected to the frame 1. The heat dissipation component 6 is disposed above the first conveyor belt mechanism 12. The heat dissipation component 6 includes a heat dissipation support frame 61, a heat dissipation fan 62, and a heat dissipation fan protective net 63. The heat dissipation support frame 61 is connected to the vertical rod of the frame 1. The fan blades of the heat dissipation fan 62 face the first conveyor belt mechanism 2, and a heat dissipation fan protective net 63 is disposed below the heat dissipation fan 62. In this embodiment, the heat dissipation component 6 can initially cool the film with a high temperature during conveying, preventing adhesion during the turning process.

[0035] like Figure 1 As shown, the device also includes an auxiliary conveyor belt mechanism 5 for cooperating with the first conveyor belt mechanism 2 and the second conveyor belt mechanism 3; the auxiliary conveyor belt mechanism 5 is used to cooperate with equipment such as a rubber mixing mill to achieve continuous and cyclic operation.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
