[0021] Reference Figure 1 and Figure 2 In order to reduce the probability that the work of removing rubber containing metal impurities interferes with the normal operation of the production line, the embodiment of the present application provides a metal impurity removal system for rubber production, including: Conveyor belt 1, used to drive the rubber material to move; A metal detection device 2, used to detect metal impurities in the rubber material moving above the conveyor belt 1; The MCU controller is used to receive the metal impurity information transmitted by the metal detection device 2 and generate a control signal for controlling the movement of the impurity removal device 3 at the corresponding position; A plurality of impurity removal devices 3 are spaced apart along the width direction of the conveyor belt 1 and are used to remove the rubber material according to the received control signal; Wherein, the impurity removal device 3 comprises: A transverse driving member 31, whose output shaft is arranged parallel to the moving direction of the conveyor belt 1, and whose control end is connected to the MCU controller; A lifting cylinder 32 connected to the transverse driving member 31, the piston rod of the lifting cylinder 32 is perpendicular to the surface of the conveyor belt 1, the control end is connected to the MCU controller, and a pressure sensor connected to the MCU controller is arranged in the inner cavity; The ultrasonic cutting knife 33 is fixedly connected to the piston of the lifting cylinder 32, and the blade head 332 of the ultrasonic cutting knife 33 is arranged toward the side close to the conveyor belt 1, and its control end is connected to the MCU controller.

[0022] The control end of the conveyor belt 1 is connected to the MCU controller for transmitting its own movement speed to the MCU controller so that the MCU controller can control the movement speed of the transverse drive member 31, thereby ensuring the relative stillness of the ultrasonic cutting knife 33 and the rubber material containing metal impurities in the horizontal direction.

[0023] Exemplarily, the metal detection device 2 can be implemented as a multi-physical field fusion detection device, which determines the horizontal coordinates of metal impurities in the rubber by combining electromagnetic induction and terahertz imaging, and transmits the corresponding horizontal coordinates of the metal impurities to the MCU controller, so that the MCU controller can select the magazine removal device to perform metal impurity removal according to the horizontal coordinates of the metal impurities.

[0024] In order to facilitate the processing of metal impurities distributed in the rubber material, in the embodiment of the present application, a plurality of impurity removal devices 3 are arranged along the width direction of the conveyor belt 1, and each impurity removal device 3 removes the rubber material containing metal impurities under the drive of the MCU controller.

[0025] Furthermore, the staff can analyze the frequency of use of the ultrasonic cutting knife 33 to obtain the ultrasonic cutting knife 33 that is used frequently, and provide data reference for the maintenance and improvement of the previous mixing process.

[0026] In a metal impurity removal system for rubber production provided by an embodiment of the present application, a metal detection device 2 is used to detect metal impurities in the rubber on a conveyor belt 1, and an MCU controller is used to control an impurity removal device 3 corresponding to the position of the metal impurities to perform an impurity removal operation, wherein a transverse drive member 31 is used to keep an ultrasonic cutter 33 and the rubber with metal impurities on the conveyor belt 1 relatively still, and a lifting cylinder 32 is used to drive the ultrasonic cutter 33 close to the conveyor belt 1, and at the same time, the ultrasonic cutter 33 removes the rubber containing metal impurities by its own vibration. At the same time, in the process of removing metal impurities, the cutting pressure fed back in real time by the pressure sensor is used, and combined with the thickness of the rubber, the power of the ultrasonic cutter 33 is dynamically adjusted by the MCU controller, thereby effectively solving the defect in the prior art that the production line needs to be shut down when cutting metal impurities in the rubber, and improving the efficiency of cleaning the metal impurities in the rubber.

[0027] Optionally, the transverse driving member 31 can be implemented as a driving hydraulic cylinder or a linear motor arranged along the movement direction of the conveyor belt 1. In the embodiment of the present application, the transverse driving member 31 is implemented as a linear motor, and the movement direction of the linear motor is parallel to the movement direction of the conveyor belt 1. The housing of the linear motor is fixedly connected to the housing of the lifting cylinder 32 by bolts.

[0028] By implementing the transverse drive member 31 as a linear motor and using the MCU controller to control the movement speed of the linear motor, it is convenient for the lifting cylinder 32 to remain relatively stationary along the movement direction of the conveyor belt 1, so that the lifting cylinder 32 can drive the ultrasonic cutting knife 33 to cut and remove the rubber containing metal impurities.

[0029] Optionally, in order to ensure that the ultrasonic cutting blade can remove the rubber material containing metal impurities, the ultrasonic cutting blade 33 provided in the embodiment of the present application includes: The ultrasonic knife holder 331 is fixedly connected to the piston rod of the lifting cylinder 32, and the ultrasonic knife holder 331 is provided with a positioning groove, the opening direction of the positioning groove is perpendicular to the moving direction of the conveyor belt 1, and the cross-sectional shape of the positioning groove is T-shaped; The cutter head 332 is slidably connected in the positioning groove; The locking bolt 333 is threadedly connected to the side wall of the ultrasonic knife holder 331 and is in contact with the outer wall of the knife head 332 .

[0030] In order to facilitate the timely replacement of the blade head 332 of the ultrasonic cutting knife 33 and reduce the defect that the connection between the blade head 332 and the ultrasonic blade holder 331 shakes during use and affects the cutting efficiency, the cross-sectional shape of the positioning groove in the embodiment of the present application is set to a T-shape, and the positioning groove is horizontally opened and perpendicular to the movement direction of the conveyor belt 1. The side wall of the positioning groove is used to limit the blade head 332 along the movement direction of the conveyor belt 1. Furthermore, the locking bolt 333 is used to tighten the blade head 332, thereby ensuring that the blade head 332 removes the rubber material containing metal impurities perpendicular to the conveyor belt 1.

[0032] The first blade, the second blade, the third blade and the fourth blade are arranged around and integrally formed, and the heights of the first blade and the third blade are both higher than the height of the second blade. The first blade and the third blade are used to contact the rubber material first and pre-position the rubber material, and then the piston rod of the driving cylinder drives the ultrasonic cutting knife 33 to continue to approach the conveyor belt 1, and the second blade and the fourth blade contact the rubber material, thereby improving the convenience of cleaning the rubber material containing metal impurities.

[0034] In combination with the first aspect, in a possible implementation, the outer wall of the cutter head 332 is provided with a high temperature resistant ceramic coating.

[0035] By setting a high-temperature resistant ceramic coating on the outer wall of the cutter head 332 , the cutter head 332 of the ultrasonic cutting knife 33 is protected to adapt to the high-temperature rubber material treatment after the vulcanization process, thereby increasing the service life of the cutter head 332 .

[0036] In combination with the first aspect, in a possible implementation manner, the method further includes: A monitoring camera is fixedly connected to a side of the ultrasonic knife holder 331 close to the knife head 332, and an image acquisition port of the monitoring camera is arranged toward the knife head 332; The wireless communication module is connected to the surveillance camera for transmitting the images collected by the surveillance camera to the cloud.

[0037] By using surveillance cameras to collect the wear conditions of each cutter head 332 and transmitting the collected images to the cloud via surveillance cameras, it is possible to reliably detect the working status of the cutter head 332 and reduce the labor intensity of operators staying on site for a long time.

[0039] Exemplarily, the support bracket 4 is vertically arranged, and the support bracket 4 is welded and fixed to the frame of the conveyor belt 1 .

[0040] The adjustment bracket 5 is fixedly connected to the supporting bracket 4 by bolts, and the adjustment bracket 5 is horizontally arranged. The length direction of the adjustment bracket 5 is perpendicular to the movement direction of the rubber to be removed, and a threaded hole for connecting the metal detection device 2 is arranged on the adjustment bracket 5.

[0041] By using the support bracket 4 and the adjustment bracket 5, the metal detection device 2 is horizontally arranged above the rubber material, thereby improving the convenience of the metal detection device 2 in detecting and identifying metal impurities in the rubber material and avoiding the probability of errors and omissions in the detection process of metal impurities.

[0042] Optionally, a metal impurity removal system for rubber production provided in an embodiment of the present application further includes: There are multiple warning devices 6, each of which is electrically connected to a linear motor and emits an audible and visual warning when the corresponding linear motor moves.

[0043] Exemplarily, the warning device 6 is implemented as a warning light or an audible and visual alarm.

[0044] By issuing a warning through the warning device 6 when the linear motor moves, it is convenient to remind the staff on site to pay attention and avoid the staff from being hurt.
