Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a tread extrusion cutting knife noise reduction device. Background Art

[0002] As we all know, tread extrusion is one of the tire component manufacturing processes. After the tread is extruded, it passes through a transport roller and enters the cutting area for automatic cutting according to a fixed length. During the cutting process, the motor and air duct cause the regional noise decibel to exceed 85. The national noise safety and environmental protection limit for the working environment shall not exceed 85 decibels. The actual noise level is 90 decibels, which has endangered the working environment and caused pollution. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tread extrusion cutter noise reduction device to improve the working environment and reduce noise pollution.

[0004] The utility model solves the technical problem by adopting the following technical solution: a tread extrusion cutter noise reduction device is provided with a cutter device, the cutter device is composed of a cutter, a nozzle, a cutter shield, a nozzle connecting rod, an air blowing pipe and a water spraying pipe, and is characterized in that a rectangular soundproof cover is provided on the outer cover of the cutter device, the soundproof cover is a sandwich structure, the sandwich is soundproof cotton, the outer part of the soundproof cotton is wrapped with an aluminum alloy plate, a sliding door is installed on one side of the soundproof cover, a door handle is installed on the right side of the sliding door, a safety door switch is installed on the lower right side of the door handle, the safety door switch is connected to the power control end of the cutter device via a switch cable, and the switch cable is located below the safety door switch.

[0005] The beneficial effects of the utility model are simple structure, practicality and convenience, greatly reducing noise environmental pollution and avoiding harm caused by the current occupational situation. 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. sound insulation cover, 1-1. aluminum alloy plate, 1-2. sound insulation cotton, 2-1. sliding door, 2-2. door handle, 2-3. safety door switch, 2-4. switch cable, 3. cutter device, 3-1. cutter, 3-2. nozzle, 3-3. cutter guard, 3-4. nozzle connecting rod, 3-5. blow pipe, 3-6. water spray pipe. DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a cutting device 3, which is composed of a cutting knife 3-1, a nozzle 3-2, a cutting knife shield 3-3, a nozzle connecting rod 3-4, a blowing pipe 3-5 and a water spraying pipe 3-6. The outer cover of the cutting device 3 is equipped with a rectangular soundproof cover 1, the soundproof cover 1 is a sandwich structure, and its sandwich is soundproof cotton 1-2, and the outer surface of the soundproof cotton 1-2 is wrapped with an aluminum alloy plate 1-1. A sliding door 2-1 is installed on one side of the soundproof cover 1, and a door handle 2-2 is installed on the right side of the sliding door 2-1. A safety door switch 2-3 is installed at the lower right of the door handle 2-2. The safety door switch 2-3 is connected to the power control end of the cutting device 3 through a switch cable 2-4, and the switch cable 2-4 is located below the safety door switch 2-3. When the sliding door 2-1 is opened, the cutting device 3 will automatically stop, and the cutting knife 3-1 will stop rotating to prevent accidents. When the sliding door 2-1 is completely closed, the equipment can be started. The cutter 3-1 is below the cutter device 3 and is inclined at a certain angle according to actual process standards. The nozzle 3-2 is connected to the cutter shield 3-3 by the nozzle connecting rod 3-4 and is fixed on one side of the cutter 3-1. One end of the air blowing pipe 3-5 and the water spraying pipe 3-6 are connected to the nozzle 3-2, and the other end is connected to the air source and water source of the equipment.
