Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a metal-free automatic glue supplying device. Background Art

[0002] During the calendering machine production, the open mill supplies rubber to the calendering machine through a conveyor belt. During the rubber supply process, metal impurities often appear in the rubber, causing roller damage and material abnormalities.

[0003] At present, metal detection in rubber materials is carried out by installing a metal detector on the conveyor belt to detect the conveyed rubber materials. When metal is detected, the metal detector transmits the detection signal to the controller, which then controls the conveyor belt to stop. Finally, the operator climbs onto the platform to tear off the rubber materials with metal, and then adjusts the controller to make the conveyor belt work again. The operation of manually climbing up to tear off the rubber materials is not only time-consuming and laborious, but also there are certain safety hazards in the high-altitude operation. Summary of the Invention

[0004] The purpose of the utility model is to address the defects of the existing technology and provide a metal-free automatic glue supply device, which can detect when the glue contains metal and actively cut the glue containing the metal part, while controlling the lowering of the second conveyor belt to drop the cut metal-containing glue segments into a collection frame.

[0005] The technical solution of the utility model is: a metal-free automatic glue supply device, comprising a frame and a controller, wherein a first conveyor belt arranged obliquely is installed at the front end of the frame, and a second conveyor belt for receiving the glue conveyed by the first conveyor belt is installed at the rear end of the frame;

[0006] The first conveyor belt is provided with a metal detector for detecting the conveyed rubber material, and a cutting mechanism for cutting the conveyed rubber material. The first conveyor belt, the second conveyor belt, the metal detector and the cutting mechanism are all electrically connected to the controller;

[0007] The rear end of the second conveyor belt is hinged to the frame, and an electric telescopic mechanism is provided between the front end of the second conveyor belt and the frame to drive the second conveyor belt to rotate and swing up and down. The electric telescopic mechanism is electrically connected to the controller and controlled by the controller. A collection frame for receiving the fallen and cut rubber materials is provided below the second conveyor belt.

[0008] Preferably, the cutting mechanism includes a stepper motor and a cutter, and brackets are provided on both sides of the first conveyor belt. The middle part of the cutter is provided with a rotating shaft that is rotatably connected to the brackets on both sides. The output shaft of the stepper motor is connected to one end of the rotating shaft to drive the cutter to rotate.

[0009] Preferably, the first conveyor belt and the second conveyor belt are both metal mesh conveyor belts.

[0010] Preferably, the electric telescopic mechanism is arranged obliquely, with one end of the electric telescopic mechanism being hinged to the front end of the second conveyor belt, and the other end being hinged to the frame.

[0011] Preferably, the electric telescopic mechanism is an electric hydraulic rod.

[0012] Compared with the prior art, the utility model has the following advantages: when it is detected that the rubber material contains metal, the utility model can actively cut the rubber material containing the metal part, and at the same time control the lower swing of the second conveyor belt to drop the cut rubber material segment containing metal into the collection frame, with a high degree of automation, reduced labor intensity and risk, and improved work efficiency.

[0016] The present invention is further described below with reference to the accompanying drawings and embodiments. Example 1

[0017] like Figure 1 and Figure 2 , a metal-free automatic glue supply device, including a frame 5 and a controller.

[0018] A tilted first conveyor belt 1 is installed at the front end of the frame 5, and a second conveyor belt 4 for receiving the rubber material conveyed by the first conveyor belt 1 is installed at the rear end of the frame 5. Both the first conveyor belt 1 and the second conveyor belt 4 are metal mesh conveyor belts.

[0019] The first conveyor belt 1 is provided with a metal detector 2 for detecting the conveyed rubber material, and a cutting mechanism 3 for cutting the conveyed rubber material. The first conveyor belt 1, the second conveyor belt 4, the metal detector 2 and the cutting mechanism 3 are all electrically connected to the controller.

[0020] The rear end of the second conveyor belt 4 is hinged to the frame 5 , and an electric telescopic mechanism 6 is provided between the front end of the second conveyor belt 4 and the frame 5 for driving the second conveyor belt 4 to rotate and swing up and down.

[0021] The electric telescopic mechanism 6 is arranged obliquely, with one end of the electric telescopic mechanism 6 being hinged to the front end of the second conveyor belt 4 , and the other end being hinged to the frame 5 .

[0022] The electric telescopic mechanism 6 is an electric hydraulic rod, which is electrically connected to the controller and controlled by the controller. A collection frame 7 for receiving the fallen and cut rubber materials is provided below the second conveyor belt 4 .

[0023] Working principle:

[0024] When in use, the rubber material is conveyed from the first conveyor belt 1 to the second conveyor belt 4, and then sent to the next process by the second conveyor belt 4;

[0025] When the metal detector 2 detects that the rubber material on the first conveyor belt 1 contains metal, the first conveyor belt 1 stops, and then the cutting mechanism 3 performs the first cutting. Then the first conveyor belt 1 runs for a while to allow the rubber material containing the metal part to pass the position of the cutting mechanism 3. Then the first conveyor belt 1 stops again, and then the cutting mechanism 3 performs the second cutting to cut off the rubber material segment containing the metal.

[0026] When the cut rubber segment is conveyed to the second conveyor belt 4, the electric telescopic mechanism 6 drives the second conveyor belt 4 to swing downward, dropping the rubber segment into the collection frame 7, and then the second conveyor belt 4 is reset to continue conveying.

[0027] The conveying, cutting, and swinging of the second conveyor belt 4 in the entire process are all controlled by the controller, and its control logic mainly realizes automatic active cutting and dropping the cut rubber material into the collection box 7 by adjusting the conveying speed and delaying the start. Example 2

[0028] This embodiment is optimized based on the above embodiment, specifically optimizing the cutting mechanism 3.

[0029] like Figure 2 The cutting mechanism 3 includes a stepping motor 10 and a cutting knife 8 , and brackets 11 are correspondingly provided on both sides of the first conveyor belt 1 .

[0030] A rotating shaft 9 rotatably connected to brackets 11 on both sides is provided in the middle of the cutter 8 , and an output shaft of a stepping motor 10 is connected to one end of the rotating shaft 9 for driving the cutter 8 to rotate.

[0031] By controlling the stepper motor 10 to rotate at a certain angle, the blade of the cutter 8 is rotated onto the rubber material so as to cut the rubber material.

[0032] The present invention is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still fall within the scope of protection of the present invention.
