Description

Technical Field

[0001] The utility model relates to the field of winding machines, in particular to a film winding device for producing solar cell sheets. Background Art

[0002] During the production of solar panel film, the produced film needs to be rolled up into a roll using a winder and then stored. In the Chinese utility model patent with the announcement number CN220744820U, a film winder is disclosed, which can limit and guide the film during the winding process, improve the position accuracy of the film, reduce the deviation of the film during the winding process, and improve the winding effect of the film. The solar panel film can be bent and rolled, but it has a certain toughness. The above structure does not provide a corresponding structure for fixing multiple solar panel films, which makes it impossible for the solar panel film to effectively fit on the surface of the winding roller in the initial stage, and thus cannot be effectively rolled. For this reason, we designed a film winding device for solar cell production. Utility Model Content

[0003] In order to solve the technical problem that the solar cell panel film cannot be effectively attached to the surface of the winding roller in the initial stage and thus cannot be effectively wound, the utility model provides a film winding device for solar cell production.

[0004] The utility model is implemented by the following technical scheme: a film winding device for producing solar cell sheets, comprising a frame, a winding roller is rotatably mounted on the frame through a bearing seat, a plug-in slot is opened at the right end of the winding roller, and a pressing plate is movably mounted in the plug-in slot;

[0005] A baffle is fixed on the left end of the winding roller, and a pressure plate is slidably sleeved on the right side of the winding roller, a ring is welded on the right surface of the pressure plate, the ring is sleeved on the winding roller, and a threaded hole is opened on the ring, a bolt is threadedly connected to the threaded hole, and the bottom end of the bolt is tightly fitted with the outer ring surface of the winding roller.

[0006] As a further improvement of the above scheme, a driven sprocket is installed at the rear end of the winding roller, a driving motor is installed on the frame, a driving sprocket is installed on the output shaft of the driving motor, and the driving sprocket is connected to the driven sprocket by a chain. The driving motor can rotate the winding roller, thereby enabling the solar panel film to be wound around the winding roller.

[0007] As a further improvement of the above solution, guide grooves are provided at both left and right ends of the outer ring surface of the winding roller, and guide holes are provided in the guide grooves and communicated with the plug-in grooves;

[0008] Threaded holes are provided on both sides of the lower surface of the pressing plate, and a guide column is slidably arranged in the guide hole. A locking screw is arranged on the guide column, and the locking screw is threadedly connected to the pressing plate. The inner diameter of the threaded hole is smaller than that of the guide hole, and the inner diameter of the guide hole is smaller than the inner diameter of the guide groove, which can quickly connect the guide column to the pressing plate and ensure that the pressing plate can only be installed and moved along a specified path, and is also convenient for subsequent disassembly and maintenance.

[0009] As a further improvement of the above solution, the outer ring surface of the winding roller is provided with mounting grooves at both ends, the mounting grooves are provided with screw holes and are connected with the plug-in grooves, and the lower surface of the pressing plate is provided with grooves at both sides;

[0010] The screw hole has a mounting bolt threadedly connected thereto, and a sleeve column is provided on the mounting bolt, a compression spring is sleeved on the sleeve column, the other end of the compression spring abuts against the groove, the compression spring is sleeved on the sleeve column and extends into the screw hole, so that the upper end of the compression spring is placed in the groove, and the mounting bolt is connected to the screw hole, so that the compression of the compression spring on the compression plate can be completed, and changing the connection depth of the mounting bolt can change the extrusion force of the compression spring on the compression plate.

[0011] As a further improvement of the above solution, the outward side of the guide column and the mounting bolt are respectively placed in the guide groove and the mounting groove and are not outside the outer ring surface of the winding roller, so as not to scratch the surface of the solar panel film.

[0012] As a further improvement of the above scheme, the two edges at the top of the plug-in slot of the winding roller are chamfered to form a contact arc surface, and the outward surface of the pressing plate is chamfered to form a connecting arc surface. One end of the solar panel film can be plugged into the plug-in slot and placed directly between the pressing plate and the plug-in plate without causing scratches to them.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a plug-in slot on the winding roller, and a pressing plate that moves forward and backward is provided in the plug-in slot. Under the action of a compression spring, the pressing plate can press one end of the solar cell film between the pressing plate and the plug-in slot, thereby fixing one end of the film, facilitating subsequent winding operations and quick disassembly;

[0015] 2. By fixing a baffle on the winding roller and cooperating with a pressure plate that moves left and right, the distance between the baffle and the pressure plate can be adjusted as needed, so that it is suitable for solar cell films of various widths, and can be positioned during the winding process to prevent its position from shifting.

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0026] A baffle plate 3 is fixed to the left end of the winding roller 2, and a pressure plate 4 is slidably sleeved on the right side of the winding roller 2. A ring 41 is welded on the right surface of the pressure plate 4, and the ring 41 is sleeved on the winding roller 2. A threaded hole is opened on the ring 41, and a bolt is threadedly connected to the threaded hole. The bottom end of the bolt fits tightly with the outer ring surface of the winding roller 2.

[0027] A driven sprocket is installed at the rear end of the winding roller 2, a driving motor is installed on the frame 1, and a driving sprocket is installed on the output shaft of the driving motor. The driving sprocket and the driven sprocket are connected by a chain. The driving motor can make the winding roller 2 rotate, and then the solar cell film can be wound on the winding roller 2.

[0028] The outer ring surface of the winding roller 2 is provided with guide grooves 22 at both left and right ends, and the guide grooves 22 are provided with guide holes 221 which are connected with the plug-in grooves 21;

[0029] Threaded holes are provided on both sides of the lower surface of the pressing plate 5, and a guide column 6 is slidably arranged in the guide hole 221. A locking screw 61 is arranged on the guide column 6, and the locking screw 61 is threadedly connected to the pressing plate 5. The inner diameter of the threaded hole is smaller than that of the guide hole 221, and the inner diameter of the guide hole 221 is smaller than the inner diameter of the guide groove 22, which can quickly connect the guide column 6 to the pressing plate 5 and ensure that the pressing plate 5 can only be installed and moved along the specified path, which is also convenient for subsequent disassembly and maintenance.

[0030] The outer ring surface of the winding roller 2 is provided with mounting grooves 23 at both ends, and the mounting grooves 23 are provided with screw holes 231 which are connected with the plug-in grooves 21. The lower surface of the pressing plate 5 is provided with grooves at both sides.

[0031] The screw hole 231 is threadedly connected with a mounting bolt 7, and a socket column 71 is provided on the mounting bolt 7, and a compression spring 8 is socketed on the socket column 71, and the other end of the compression spring 8 abuts in the groove, and the compression spring 8 is socketed on the socket column 71 and extends into the screw hole 231, so that the upper end of the compression spring 8 is placed in the groove, and the mounting bolt 7 is connected to the screw hole 231, so that the compression of the compression spring 8 on the compression plate 5 can be completed. Changing the connection depth of the mounting bolt 7 can change the extrusion force of the compression spring 8 on the compression plate 5.

[0032] The outward side of the guide column 6 and the mounting bolt 7 are respectively placed in the guide groove 22 and the mounting groove 23 and are not outside the outer ring surface of the winding roller 2, so as not to scratch the surface of the solar cell film.

At this time, one end of the film is inserted between the pressing plate 5 and the plug-in groove 21 (that is, the pressing plate 5 has a side with a connecting arc surface 51). Since a pressing spring 8 is provided between the pressing plate 5 and the plug-in groove 21, and the pressing spring 8 makes the pressing plate 5 have a tendency to move to the left, so that the film can be pressed between the pressing plate 5 and the plug-in groove 21, the power supply of the driving motor can be turned on at this time, and the driving motor can make the winding roller 2 rotate, so that the solar cell film can be wound on the winding roller 2. After the winding is completed, the pressure plate 4 is removed, and the rolled solar cell film can be pulled out to the right as a whole;

[0035] By providing a plug-in slot 21 on the winding roller 2, and providing a pressing plate 5 that moves forward and backward in the plug-in slot 21, the pressing plate 5 can press one end of the solar cell film between the pressing plate 5 and the plug-in slot 21 under the action of the pressing spring 8, thereby fixing one end of the film, facilitating subsequent winding operations, and facilitating quick disassembly;

[0036] By fixing a baffle plate 3 on the winding roller 2 and cooperating with a pressure plate 4 that is movable left and right, the distance between the baffle plate 3 and the pressure plate 4 can be adjusted as needed, so that it is suitable for solar cell film of various widths, and can be positioned during the winding process to prevent its position from shifting.
