[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] As described in the background technology, in the related technology, the plastic wrap of the rubber needs to be peeled off manually, and a single heater is placed at the front end or the rear end of the laminating template. The position of the heater is fixed. No matter what specifications of tires are made, only one end of the rubber is heated. This technical structure is simple, and the operator's work intensity is high. At the same time, only one end of the material head can be heated, and the other end is at room temperature, which has a very limited improvement in the quality of the joint.

[0023] To solve the above problems, see Figure 1 and Figure 2As shown, an embodiment of the present invention provides a tread rubber film tearing system. The tread rubber film tearing system of this embodiment includes a frame 10, a film tearing device 30, a first heating device 40 and a second heating device 50. The first end of the frame 10 is provided with a pressing device 20, and the pressing device 20 is used to fix the first end of the tread rubber; the film tearing device 30 is movably arranged on the frame 10, and a film tearing roller 32 is arranged on the film tearing device 30. The cling film to be torn is wound on the film tearing roller 32, and the film tearing device 30 moves from the first end of the frame 10 to the second end of the frame 10; the first heating device 40 is arranged at the first end of the frame 10; the second heating device 50 is arranged on the film tearing device 30, and when the film tearing device 30 moves to the second end of the frame 10, the second heating device 50 can heat the second end of the tread rubber. During operation, the first end of the tread rubber is fixed to the first end of the frame, and the end of the cling film to be torn is wound on the film-tearing roller, and the film-tearing roller automatically peels the cling film from the rubber material. Specifically, the film-tearing roller starts to peel the cling film from the first end of the frame, i.e., the front end, and moves to the second end of the frame, i.e., the tail end, to end the peeling work. After the peeling work of the cling film is completed, the second heating device moves with the film-tearing device, and can automatically detect the tail of the tread rubber material. When the second heating device moves to the top of the tail of the material, it starts heating. The first heating device can heat the first end of the tread rubber at any time. The present invention integrates the film-tearing roller and the second heating device without increasing the length of the frame, thereby realizing semi-automatic peeling of the cling film and simultaneous controllable heating of the front and rear edges of the tread rubber. The first heating device and the second heating device both include electric heaters. Of course, other heating devices can also be used to achieve heating of the front and rear edges of the rubber material.

[0024] In order to realize the transmission of the rubber material, a plurality of transmission rollers 11 are arranged on the frame 10 in this embodiment, and the plurality of transmission rollers 11 are arranged at intervals along the length direction of the frame 10. During operation, the head of the tread rubber can be transmitted to the first end of the frame through the plurality of transmission rollers. In a preferred embodiment, the transmission rollers are connected to the driving motor to realize automatic rolling.

[0025] In order to realize the automatic movement of the film tearing device, the tread rubber film tearing system in this embodiment includes a first driving unit, which is installed at the bottom of the frame 10. The film tearing device 30 includes a moving frame 31, which is connected to the first driving unit by driving, and the film tearing roller 32 is installed on the moving frame 31. When working, the first driving unit drives the moving frame to move on the frame to realize the film tearing from the first end to the second end of the tread rubber. Specifically, the first driving unit in this embodiment includes a first driving motor and a conveyor belt device 33. The bottom of the moving frame 31 is connected to the output end of the conveyor belt device 33. The first driving motor drives the conveyor belt device to operate, and drives the moving frame to move from the first end of the frame to the second end through the conveyor belt. After completing the film tearing and heating the front and rear ends of the rubber material. The first driving motor is reversed, and the moving frame is transported from the second end of the frame back to the first end of the frame through the conveyor belt.

[0026] The film peeling device 30 in this embodiment also includes a second drive motor, which is mounted on the mobile frame 31, and the film peeling roller 32 is connected to the second drive motor. After the plastic wrap joint is manually wrapped around the film peeling roller, the next process is entered, the film peeling roller rotates, and the first drive motor drives the mobile frame to move backward. When it moves to the end limiter of the stroke, the plastic wrap peeling work is completed. In order to ensure the plastic wrap peeling effect, the speed of the second drive motor and the first drive motor need to be adjusted to coordinate and match.

[0027] In order to achieve the centering of the tread rubber, the tread rubber tearing system in this embodiment also includes a centering device, which is arranged on the top of the frame 10. The centering device includes a centering convex portion 12, which passes through the gap between two adjacent driving rollers 11 and protrudes from the frame 10. The position of the centering convex portion 12 corresponds to the position of the groove in the middle of the tread rubber. The centering convex portion 12 is inserted into the groove, and a roller is arranged on the top of the centering convex portion 12.

[0028] Preferably, there are multiple centering protrusions 12 in this embodiment, and the multiple centering protrusions 12 are arranged at intervals along the length direction of the frame body 10 .

[0029] In order to prevent the rubber from warping during the peeling process of the cling film, the film peeling device 30 in this embodiment also includes a pressure roller 34, which is installed on the mobile frame 31. The pressure roller 34 presses on the tread rubber, thereby effectively preventing the rubber from warping. The film peeling device 30 also includes an infrared temperature measuring device, which is installed on the mobile frame 31. When the peeling of the cling film is completed, the second heating device and the infrared temperature measuring device are both at the rear end of the frame. The second heating device is equipped with a material detection switch, and the first drive motor starts to drive so that the mobile frame moves forward to detect the tail of the rubber. When the tail of the rubber is retrieved, it stops moving and provides working signals to the first heating device and the second heating device. After the heating starts, the infrared temperature measuring device monitors the temperature of the rubber in the heating area in real time. When it exceeds the set temperature range, it adjusts the heating power and opening and closing of the first heating device and the second heating device.

[0030] The pressing device 20 in this embodiment includes a cylinder 21, a driving frame 22 and a pressure roller 23. The cylinder 21 is installed at the bottom of the frame 10, the driving frame 22 is connected to the cylinder 21, and the pressure roller 23 is rotatably arranged on the driving frame 22. The pressing device 20 in this embodiment also includes a centering mechanism, which is installed on the frame 10. The centering mechanism includes multiple pairs of centering columns 35. A centering space is formed between two of each pair of centering columns 35, and the tread rubber is located in the centering space. When entering the rubber bonding process, multiple pairs of centering columns clamp the tread rubber so that its center coincides with the bonding center, and the centering effect is ensured by the pressure counterweight located at the upper part to prevent the rubber from deviating during the clamping process. Among them, the bonding center refers to the center of the belt drum. The pressure counterweight is arranged above the frame. The pressure counterweight includes a main body and multiple pulleys on the main body. The transmission roller transmits the tread rubber a short distance to the top of the pressure roller. The cylinder is actuated to drive the pressing roller through the driving frame, and the belt layer drum, namely the BT drum (belt layer drum), rotates to complete the material pasting work. The driving frame is a U-shaped structure to avoid the first heating device.
