[0019] The present application provides a rubber material winding device and a control method, which have the following advantages.

[0020] (1) In the present application, the swing roller can be turned up, so that the excess rubber material between the first conveyor belt and the winding reel sinks, thereby avoiding stacking or extrusion during the winding process of the rubber material.

[0025] The present application will be further described below in conjunction with the drawings and specific examples to help understand the content of the present application. The methods used in the present application are conventional methods unless otherwise specified. The raw materials and devices used are conventional commercially available products unless otherwise specified.

[0026] Example 1:

[0027] As shown in Figure 1 , the present application provides a rubber material winding device, which comprises a first conveyor belt 1, a swing rack roller 2, a second conveyor belt 3 and a winding reel 4 arranged in sequence. The first conveyor belt 1 is provided with a pressing roller. The swing rack roller 2 is provided with a first sensor 5 above. The winding reel 4 is provided with a second sensor 6 on the opposite side. The pressing roller, the first sensor 5 and the second sensor 6 are all connected with a central processor.

[0028] During the process of conveying the rubber material on the first conveyor belt 1, when the end of the rubber material moves to a designated position on the first conveyor belt 1, the pressing roller is lifted upward. At this time, the spring assembly of the pressing roller sends a rubber material conveying signal to the central processing unit. The central processing unit controls the hydraulic lifting assembly 8 to flip the swing roller 2 upward according to the signal sent by the pressing roller until the upper end face of the swing roller 2 is parallel to the upper end face of the first conveyor belt 1 and is located on the same horizontal plane. The swing roller 2 is a conveyor belt structure. The rollers of the first conveyor belt 1 and the rollers of the swing roller 2 are connected by a chain to ensure that the first conveyor belt 1 and the swing roller 2 convey the rubber material synchronously. Through the continuous conveying of the rubber material by the first conveyor belt 1, the swing roller 2 and the second conveyor belt 3, the end of the rubber material is connected to the central axis of the take-up reel 4, so that the take-up reel 4 can take up the rubber material.

[0029] During the process of winding the rubber material, the rubber material sinks on the swing roller 2 by flipping the swing roller 2, thus preventing the rubber material from piling up during the conveying process.

[0030] The first sensor 5 and the second sensor 6 are ultrasonic sensors. Due to the limitations of the application scenario, the accuracy of distance judgment cannot be guaranteed when using other sensors. Therefore, the strong anti-interference capability of ultrasonic sensors is used to ensure the accuracy of distance judgment, thereby providing accurate judgment basis for the central processing unit and ensuring that the rubber material winding operation can be carried out smoothly.

[0031] Example 2:

[0032] Depend on Figure 1 As shown, the present invention provides a control method for a rubber compound winding device, comprising the following operating steps:

[0033] Step 1: Place the adhesive material on the first conveyor belt 1 and start the first conveyor belt 1 to transport the adhesive material;

[0034] Step 2: When the detection device 7 on the first conveyor belt 1 senses that the end of the rubber material has moved to the designated position, the detection device 7 sends a control signal to the central processing unit, which controls the drive unit of the swing roller 2 to flip upward so that the upper end surface of the swing roller 2 is flush with the upper end surface of the first conveyor belt 1.

[0035] Step 3: When the rubber material is conveyed to the position of the take-up reel 4 via the first conveyor belt 1, the swing roller 2 and the second conveyor belt 3, the central processing unit controls the drive unit of the swing roller 2 to flip the swing roller 2 downward.

[0036] Step 4: When the second detection unit detects that the rubber thickness on the winding reel 4 reaches the specified thickness, the central processor controls the driving units of the first conveying belt 1 and the winding reel 4 to stop working;

[0037] Step 5: When the detection device 7 detects that the rubber end moves to the specified position of the first conveying belt 1, the winding reel 4 continues the winding action until the rubber is completely wound.

[0038] In order to solve the problem of rubber stacking on the conveying device side during the winding process, the overturning structure of the swing roller 2 is used to form a sinking of the rubber at the corresponding position of the swing roller 2 during the winding process. The detection device 7 detects the height difference between the sinking position of the rubber and the upper end surface of the first conveying belt 1, and sets a corresponding height difference value range of the detection device 7 in the central processor. The central processor controls the running speed of the first conveying belt 1 or the winding reel 4 according to the change of the height difference value of the detection device 7, so that the height difference of the sinking part of the rubber is kept within a certain numerical range, and the rubber stacking is avoided.

[0039] Further, during the winding process of the winding reel 4, the diameter of the winding reel gradually increases due to the winding of the rubber, and the gradual increase of the diameter of the winding reel may cause the winding tension of the rubber to be too large, resulting in folding of the rubber or abnormal fluctuation caused by too tight winding.

[0040] In order to avoid the above situation, in step 4, according to the change of the diameter of the rubber winding reel of the second detection unit, the central processor adjusts the winding speed of the winding reel 4, so that the winding tension of the rubber is kept stable, thereby avoiding the folding of the rubber.

[0041] In step 5, when the rubber end moves to the specified position on the first conveying belt 1, the central processor controls the first conveying belt 1 to stop running, so as to avoid the falling of the rubber end, and at the same time, the winding reel 4 continues to run. The central processor lifts the swing roller 2 upward according to the change of the height difference of the first detection unit, so as to ensure that the winding reel 4 keeps stable winding of the rubber, and at the same time, avoids the extrusion of the rubber in the sinking part during the upward overturning process of the swing roller 2.
