Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a cutting knife avoiding conveyor belt joint device. Background Art

[0002] As we all know, in the production of semi-finished tires, conveyor belts and cutters are important tools and equipment to achieve a continuous and automated production process. During the production process, the cutter may cut the conveyor belt joint, resulting in a reduction in the service life of the conveyor belt or damage to the cutter, affecting production. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a device for allowing a cutter to avoid a conveyor belt joint, thereby extending the service life of the conveyor belt and the cutter and reducing the impact on production.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a cutter avoiding conveyor belt joint device, which is provided with a conveyor belt, the two ends of the conveyor belt are connected to form a ring structure through a conveyor belt joint, and a cutter is installed above the conveyor belt. The utility model is characterized in that a switch detection piece is installed at the conveyor belt joint position, a photoelectric detection switch is installed on one side of the conveyor belt in front of the cutter, the photoelectric detection switch is connected to the signal input end of a PLC controller, and the signal output end of the PLC controller controls the cutter action.

[0005] The beneficial effect of the utility model is that the risk of the cutter cutting the conveyor belt joint is reduced to a minimum. When it is detected that the conveyor belt joint is about to be cut during the operation of the equipment, the joint is avoided in time to prevent the cutter from cutting the conveyor belt joint, thereby protecting the cutter and the conveyor belt from damage, reducing the occurrence of malfunctions, and improving the operation efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 A schematic structural diagram of the utility model.

[0008] In the figure, 1. photoelectric detection switch, 2. conveyor belt, 3. cutter, 4. switch detection sheet, 5. conveyor belt joint. DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a conveyor belt 2, the two ends of the conveyor belt 2 are connected to form a ring structure through a conveyor belt joint 5, a cutter 3 is installed above the conveyor belt 2, a switch detection piece 4 is installed at the position of the conveyor belt joint 5, and a photoelectric detection switch 1 is installed on one side of the conveyor belt in front of the cutter 3. The photoelectric detection switch 1 is connected to the signal input end of the PLC controller, and the signal output end of the PLC controller controls the action of the cutter 3.

[0010] During the transmission of the conveyor belt 2, the photoelectric detection switch 1 senses the position of the switch detection piece 4 by emitting a photoelectric signal, so that the PLC controller can determine the distance of the conveyor belt joint 5. Each time the photoelectric detection switch 1 detects the conveyor belt joint 5, the actual number of meters will be compared with the set number of meters. When the comparison value is greater than the distance from the photoelectric detection switch 1 to the cutter 3, the PLC controller controls the cutter 3 not to cut the conveyor belt joint 5 during the cutting process, and the program does not intervene in the cutting length, and the cutting proceeds normally; when the comparison value is equal to or less than the distance from the photoelectric detection switch 1 to the cutter 3, the cutter 3 may cut the conveyor belt joint 5 during cutting. At this time, the program will automatically increase the set value of the number of meters to intervene in the cutting length, so that the conveyor belt joint 5 can successfully avoid the cutter 3, and the cutter 3 will not cut the conveyor belt joint 5, thereby ensuring the safety of the cutter 3 and the conveyor belt 2, reducing failures and improving production efficiency.

Claims
