This design concept is novel, the design is scientific, has huge economic benefits and broad market prospects, and is worthy of popularization and use.

[0003] However, this device has the following drawbacks: although the roller can be replaced, after winding is completed, the roller must be replaced before another roller can be installed to continue winding the composite film. The roller replacement process is too time-consuming, thus affecting production efficiency. To address the above drawbacks, we propose a collection device for composite film production. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a collecting device for composite membrane production.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solution: a collecting device for composite membrane production, comprising:

[0006] The winding structure includes a winding frame, a rotating shaft slidably mounted on the left side of the winding frame, and two winding assemblies rotatably mounted on the surface of the rotating shaft, and two through slots for the two winding assemblies to pass through are respectively opened on the front side of the winding frame;

[0007] The drive structure includes a drive frame, two sleeves respectively rotatably mounted on the left side of the drive frame, and a fixing assembly arranged on the inner wall of the sleeve for fixing the winding assembly; and a motor for driving the sleeve to rotate is fixedly mounted on the right side of the drive frame;

[0008] The winding assembly includes two rotating rings rotatably mounted on the surface of the rotating shaft, a connecting shaft fixedly mounted on the outer annular surface of the rotating ring, and a winding shaft rotatably mounted on the right end of the connecting shaft;

[0009] The limiting structure is arranged on the left side of the winding frame and is used to limit the two winding components.

[0010] Preferably, the fixing assembly includes a cross slot provided at the left end of the sleeve, and a cross pin slidably mounted on the inner wall of the cross slot.

[0011] Preferably, a cross slot for inserting a cross pin is provided at the right end of the winding shaft, a retaining ring is fixedly mounted on the surface of the cross pin, and a compression spring is sleeved on the surface of the cross pin.

[0012] Preferably, one end of the compression spring is fixedly connected to the right end of the retaining ring, and the other end of the compression spring is overlapped with the left side surface of the driving frame.

[0013] Preferably, the limiting structure includes an electric telescopic rod fixedly mounted on the left side of the winding frame, two limiting blocks fixedly mounted on the surface of the rotating shaft, and two limiting grooves respectively provided on opposite sides of the two rotating rings.

[0014] Preferably, the telescopic end of the electric telescopic rod is fixedly connected to the upper end of the rotating shaft.

[0015] Preferably, the limiting groove allows the limiting block to be inserted.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up a winding structure and a driving structure, pulling the retaining ring to the right can drive the cross pin out of the cross slot, and then rotating the winding shaft can drive the rotating ring to rotate along the axis of the rotating shaft. Then the rolled composite film can be taken out of the winding shaft, and at this time, the other winding shaft on the winding frame continues to roll up the composite film. Compared with the existing technology, the device uses a fixed component in conjunction with a rotatable connecting shaft to rotate the winding shaft wrapped with the composite film to the front of the winding frame. Without affecting the winding of the composite film by the other winding shaft, the idle winding shaft can be used to take the material, thereby improving production efficiency.

[0018] 2. By setting a limit structure, when the electric telescopic rod is in the reset state, one of the limit blocks on the rotating shaft will be inserted into the limit groove on the surface of the rotating ring above the winding frame, and the other limit block on the rotating shaft will be disengaged from the limit groove on the surface of the rotating ring below the winding frame. Therefore, when taking material, one limit block can be driven to disengage from the limit groove on the surface of the rotating ring where material needs to be taken, and the other limit block will be inserted into the limit groove on the surface of the other rotating ring, thereby limiting the other winding shaft that is winding the composite film, thereby ensuring the stability of the winding shaft.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-7 The utility model provides a technical solution: a collecting device for composite film production, including: a winding structure, a driving structure, and a limiting structure.

[0030] See Figure 1 The winding structure includes a winding frame 1, a rotating shaft 2 slidably installed on the left side of the winding frame 1, and two winding components respectively rotatably installed on the surface of the rotating shaft 2, and two through slots for the two winding components to pass through are respectively opened on the front of the winding frame 1.

[0031] The winding assembly includes two rotating rings 6 rotatably mounted on the surface of the rotating shaft 2, a connecting shaft 7 fixedly mounted on the outer ring surface of the rotating ring 6, and a winding shaft 8 rotatably mounted on the right end of the connecting shaft 7. The winding shaft 8 can wind up the composite film.

[0032] See Figure 2 and Figure 6 The driving structure includes a driving frame 3, two sleeves 4 rotatably installed on the left side of the driving frame 3, and a fixing component arranged on the inner wall of the sleeve 4 for fixing the winding component. The fixing component includes a cross slot opened at the left end of the sleeve 4 and a cross pin 9 slidably installed on the inner wall of the cross slot; and a motor 5 that can drive the sleeve 4 to rotate is fixedly installed on the right side of the driving frame 3.

[0033] See Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The right end of the winding shaft 8 is provided with a cross slot 10 for the cross pin 9 to be inserted. A retaining ring 11 is fixedly installed on the surface of the cross pin 9. A compression spring 12 is sleeved on the surface of the cross pin 9. One end of the compression spring 12 is fixedly connected to the right end of the retaining ring 11, and the other end of the compression spring 12 overlaps the left side of the drive frame 3.

[0034] In the initial state, the compression spring 12 can drive the cross pin 9 to be inserted into the cross slot 10, so that the sleeve 4 and the winding shaft 8 can be assembled as one. At this time, the driving motor 5 can drive the winding shaft 8 to rotate, so that the composite film can be wound, and pulling the retaining ring 11 to the right can drive the cross pin 9 to disengage from the cross slot 10. Then, rotating the winding shaft 8 can drive the rotating ring 6 to rotate along the axis of the rotating shaft 2. After that, the wound composite film can be taken out of the winding shaft 8. At this time, the other winding shaft 8 on the winding frame 1 continues to wind the composite film.

[0035] Compared with the existing technology, this device uses a fixed component in conjunction with a rotatable connecting shaft 7 to rotate the winding shaft 8 wrapped with composite film to the front of the winding frame 1. Without affecting the winding of the composite film by another winding shaft 8, the idle winding shaft 8 can be used to take the material, thereby improving production efficiency.

[0036] See Figure 2 and Figure 5 The limiting structure is arranged on the left side of the winding frame 1, which is used to limit the two winding components. The limiting structure includes an electric telescopic rod 13 fixedly installed on the left side of the winding frame 1, two limiting blocks 14 fixedly installed on the surface of the rotating shaft 2, and two limiting grooves 15 respectively opened on the opposite sides of the two rotating rings 6. The limiting grooves 15 allow the limiting blocks 14 to be inserted. The telescopic end of the electric telescopic rod 13 is fixedly connected to the upper end of the rotating shaft 2.

[0037] When the electric telescopic rod 13 is in the reset state, one of the limit blocks 14 on the rotating shaft 2 will be inserted into the limit groove 15 on the surface of the rotating ring 6 above the winding frame 1, and the other limit block 14 on the rotating shaft 2 will be disengaged from the limit groove 15 on the surface of the rotating ring 6 below the winding frame 1. Therefore, when taking material, one limit block 14 can be driven to disengage from the limit groove 15 on the surface of the rotating ring 6 from which material needs to be taken, and at this time, the other limit block 14 will be inserted into the limit groove 15 on the surface of the other rotating ring 6, thereby limiting the other winding shaft 8 that is winding the composite film, thereby ensuring the stability of the winding shaft 8.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
