[0003] The main purpose of this utility model is to provide a forming drum and forming machine to solve the problem of the inability to calibrate in a timely manner during the tire forming production process in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a forming drum is provided, comprising a housing; a main shaft rotatably connected to the housing; a side drum assembly axially movably disposed on the main shaft and rotating with the main shaft; a measuring element disposed on the side drum assembly and moving with the side drum assembly; a calibration element disposed on the main shaft, wherein the measuring element is capable of detecting its position relative to the calibration element to obtain the moving position of the side drum assembly; and a controller electrically connected to both the measuring element and the side drum assembly, wherein the controller receives detection information from the measuring element and controls the side drum assembly to perform movement correction based on the detection information.

[0005] Furthermore, the forming drum also includes a signal transmitter, which is mounted on the spindle and electrically connected to the measuring piece.

[0008] Furthermore, the forming drum also includes a signal adapter, which is mounted on the chassis and located between the signal transmitter and the signal receiver. The signal adapter is used to receive signals from the signal transmitter and transmit the signals to the signal receiver.

[0009] Furthermore, the signal transmitter and signal adapter are wireless transmission devices; the signal adapter and signal receiver are electrically connected via cables.

[0010] Furthermore, when the signal adapter and signal receiver are electrically connected via cables, the chassis includes cable clips to secure the cables.

[0011] Furthermore, the signal adapter is detachably connected to the chassis.

[0023] To address the problem of inability to perform timely calibration during tire molding production in existing technologies, this invention provides a molding drum and a molding machine.

[0024] See Figure 1 The forming drum includes a housing 10, a main shaft 20, a side drum 31 assembly 30, a measuring element 40, a calibration element 50, and a controller 60. The main shaft 20 is rotatably connected to the housing 10. The side drum 31 assembly 30 is axially movably mounted on the main shaft 20 and rotates with the main shaft 20. The measuring element 40 is mounted on the side drum 31 assembly 30 and moves with the side drum 31 assembly 30. The calibration element 50 is mounted on the main shaft 20. The measuring element 40 can detect its position relative to the calibration element 50 to obtain the moving position of the side drum 31 assembly 30. The controller 60 is electrically connected to both the measuring element 40 and the side drum 31 assembly 30. The controller 60 receives the detection information from the measuring element 40 and controls the side drum 31 assembly 30 to perform movement correction based on the detection information.

[0025] During use, the measuring element 40, mounted on the side drum 31 assembly 30, measures the position data of the side drum 31 assembly 30. When the side drum 31 assembly 30 rotates under the drive of the main shaft 20, the calibration element 50 and the measuring element 40 provide feedback on its position after rotation. This position information is then transmitted to the controller 60, which is electrically connected to the measuring element 40, and the controller 60 corrects the position of the side drum 31 assembly 30. The timely feedback of the side drum 31 assembly 30's position via the calibration element 50 and the measuring element eliminates the need for frequent operator checks of the flatness and width data, reducing equipment downtime for inspection, improving tire production efficiency, reducing operator workload, and preventing the loss of drum flatness and width accuracy due to operator inspection intervals, thus improving tire quality.

[0026] Preferably, the calibration element 50 includes a magnetic scale, and the measuring element 40 includes a detection magnetic head.

[0027] In this application, the forming drum also includes a signal transmitter 70, which is mounted on the spindle 20 and electrically connected to the measuring element 40. The signal transmitter 70 wirelessly transmits the detection information obtained by the measuring element 40. A signal receiver 80 and a controller 60 are both mounted on the housing 10 and electrically connected. The signal receiver 80 is used to receive the signal wirelessly transmitted by the signal transmitter 70 and send it to the controller 60.

[0028] During equipment use, the controller 60 is positioned in the housing 10 or on a nearby worktable, thus its location is fixed. However, the measuring element 40 and the calibration element 50 rotate with the housing 10 of the forming drum. Therefore, a wireless connection is required between the controller 60 and the measuring element 40. This wireless connection is achieved through a signal transmitter 70 mounted on the spindle 20 and a signal receiver 80 mounted on the housing 10. This facilitates the transmission of detection information measured by the measuring element 40 to the controller 60.

[0029] In this application, the side drum 31 assembly 30 includes a side drum 31, which is movably sleeved on the outside of the main shaft 20 and located outside the chassis 10. The signal transmitter 70 is located between the side drum 31 and the chassis 10, and the distance between the signal transmitter 70 and the side drum 31 is less than the distance between the signal transmitter 70 and the chassis 10.

[0030] There is a certain installation space between the side drum 31 and the chassis 10. By placing the signal transmitter 70 between the side drum 31 and the chassis 10, it is convenient to install the signal transmitter 70. At the same time, it can reduce the obstruction of the signal transmitter 70 by other components, and make it easier for the signal receiver 80 to receive the signal from the signal transmitter 70.

[0031] In this application, the signal receiver 80 is detachably mounted on the chassis 10.

[0032] Since the signal receiver 80 is detachably mounted on the chassis 10, its position can be easily adjusted and replaced. When there is interference from other working components between the signal transmitter 70 and the signal receiver 80, the interference can be avoided by changing the position of the signal receiver 80, thereby increasing the stability of signal transmission between the signal receiver 80 and the signal transmitter 70, and also facilitating the maintenance and replacement of the signal receiver 80.

[0033] In this application, the molding drum also includes a signal adapter 90, which is disposed on the housing 10 and located between the signal transmitter 70 and the signal receiver 80. The signal adapter 90 is used to receive the signal from the signal transmitter 70 and transmit the signal to the signal receiver 80.

[0034] To improve the efficiency and stability of signal transmission between the signal transmitter 70 and the signal receiver 80, and to facilitate the placement of the signal receiver 80 and the controller 60, a signal adapter 90 is provided between the signal transmitter 70 and the signal receiver 80. The signal transmitter 70 transmits detection information to the signal adapter 90, which then transmits it to the signal receiver 80. This allows the signal receiver 80 to be placed on the operating table at a distance from the forming drum, reducing the limitations on the placement of the signal receiver 80 and the controller 60, thereby increasing the flexibility of equipment use. Preferably, the signal adapter uses a receiving antenna, which not only improves the reception of the signal transmitted from the signal transmitter 70 but also facilitates installation and setup.

[0035] In this application, the signal transmitter 70 and the signal converter 90 are wireless transmission devices. Since the signal converter is fixed while the signal transmitter 70 rotates with the main shaft 20, the signal transmitter 70 and the signal converter 90 are connected wirelessly, and both are wireless transmission devices.

[0036] In this application, the signal adapter 90 and the signal receiver 80 are electrically connected by a cable. Since the positions of both the signal adapter 90 and the signal receiver 80 are fixed, the electrical connection between them via a cable improves the stability of signal transmission.

[0037] Furthermore, when the signal adapter 90 and the signal receiver 80 are electrically connected via cables, the chassis 10 includes cable clips to secure the cables. Securely fixing the cables increases the tidiness of the equipment's working environment and reduces interference between the cables and other components. Constraining the cables also improves the ease of installation in the working environment.

[0038] In this application, the signal adapter 90 is detachably connected to the chassis 10. Because the signal adapter 90 is detachably connected to the chassis 10, it is easy to adjust the position of the signal adapter 90, minimizing interference from other components between the signal adapter 90 and the signal transmitter 70, and improving the stability of signal transmission.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] 1. The position of the side drum 31 assembly 30 is promptly fed back through the calibration component 50 and the detection component, eliminating the need for operators to frequently check the flatness and width data. This reduces equipment downtime for inspection, improves tire production efficiency, reduces the workload of operators, and avoids the problem of loss of drum flatness and width accuracy due to operator inspection time intervals, thus improving tire quality.

[0041] 2. During equipment use, the controller 60 is positioned in the housing 10 or on a nearby workbench, thus its location is fixed. However, the measuring element 40 and the calibration element 50 rotate with the housing 10 of the forming drum. Therefore, a wireless connection is required between the controller 60 and the measuring element 40. This wireless connection is achieved through a signal transmitter 70 mounted on the spindle 20 and a signal receiver 80 mounted on the housing 10. This facilitates the transmission of detection information measured by the measuring element 40 to the controller 60.
