Produced by Wuxi Bailinde Machinery Equipment Co., Ltd.: Tire cutting machine, tire shaving machine, tire trimming machine are used in the automatic tire production conveyor line. The trimmed tire will produce rubber due to the mold vent during the vulcanization process. Rubber column, tire cutting machine is used to trim the vertical tread and shoulder part of the rubber column. The equipment is connected with the conveyor line to realize semi-automatic tire trimming.

 

The tire cutting machine includes a feeding part, a cutting device and a discharging part. Hair cutting devices on the market are often complicated in structure and difficult to install and debug. Manual pruning of the rubber column has a large workload, low efficiency and high labor cost. In order to solve the above technical problems, Bailinde provides a new tyre cutting machine cutting device to achieve the purpose of simple processing, convenient debugging, fast rotation speed and fast trimming.

 

The hair cutting device of a tire cutting machine includes a frame on which a driving roller and a driven roller are horizontally arranged side by side, and the distance between the driving roller and the driven roller gradually increases along the tire movement direction; The feed end of the frame is located on the outer side of the driving roller and the driven roller, respectively, is provided with a guide roller, and the discharge end of the frame is located at the end position of the driving roller is provided with an outlet slope. The sum of the lengths of the rollers is the same as the length of the driven rollers. The bottom of the frame is provided with a motor, and the output end of the motor is provided with a motor pulley. The motor pulley is connected with the driving pulley and the driven pulley through a belt, the driving pulley is connected with the driving drum, and the driven pulley is connected with the driven drum. There are protective plates around the top of the frame, and no protective plates are provided at the feed end and the discharge end.

 

The hair cutting device of our tire cutting machine adopts two fast rotating active rollers and driven rollers installed on the frame to complete the requirement of trimming the tire hair column. There is a certain angle between the two rollers, which can be completed. For the smooth transportation of tires, the driven roller can output the tires in the tangential direction through the exit slope, and smoothly transport the tires to the discharging part. The device has simple structure, fast rotation speed and high efficiency.

Performance parameters of tire automatic shaver

 

1. Process flow of tire automatic shaver:

1.1 Barcode reading, calling process parameters (normal mode or data mode)

1.2 Entering the retread (clamped in the center)

1.3 Press roller down, tire stable rotation

1.4 The upper and lower knife sets respectively shave the rubber beard and rubber edges on the tire crown and sidewall

1.5 Equipment for resetting and kicking tires out of various institutions

2. Advantages of automatic tire shaver:

2.1 Efficiency advantage

At present, our third-generation product has a single tire cycle time increased to 13~17 seconds for semi-steel and 35-42 seconds for full-steel tires. Starting from the mechanical structure (the acceleration and deceleration of the tire, the stability of rotation, the arrangement and movement of the tool, etc.) and the electrical control (tempo setting, step connection and servoing, etc.), while ensuring the stability and effect, Achieve a shorter single cycle time.

2.2 Excellent shaving effect, no shaving

The structure of the cutter head adopts an adjustable design, and the height of the residual glue beard can be controlled by adjusting the number of standard spacers to prevent the possibility of shaving from the source. The servo of the equipment makes the stroke of the cutter head precise and controllable. Specific process parameters can be set according to the tire barcode, so as to prevent the protruding parts from being shaved, and solve the problem of tires that cannot be shaved manually, such as snow. Tires, sharp-angle tires, white tires.

2.3 Simple operation and maintenance

1. The structure of the cutter head is simple and the blade is easy to install and disassemble

2. For new or polished blades, the life of up to 10,000 copies can be reached at one time.

3. The equipment has a counting function, after the blade has reached a certain number of times, it can send out a signal to remind the tool to change

4. The guide and bearing parts of the movable parts inside the equipment have good protective measures

5. The centralized lubrication method is adopted, which greatly reduces the workload of adding grease

2.4 3S improvement

1. The all-steel type tire entrance door is side-opening and the integral steel plate structure greatly improves the internal airtightness and effectively prevents the glue from spilling out of the equipment

2. It uses an automated method to supply soft water (lubricating and cooling the blades), using soft water instead of silicon liquid to lubricate and cool the blades, which greatly reduces the adhesion of glue inside the equipment and reduces the amount of labor for workers to perform 3S cleaning.

2.5 Structural Modular Setting

In order to meet the diverse layout requirements of wire bodies in different factories, a modular design method is adopted. The tire automatic shaver is mainly composed of three parts: the tire inlet device, the shaving body, and the tire outlet device.

1. Tire inlet device: Responsible for receiving the tire input from the upper line body, and then fall into the device to perform the tire clamping operation and other operations to prepare for the next step into the shaving body. The pneumatic control system of the whole set of equipment is also installed on the device, which reduces the equipment area.

2. Shaving the main body: The tires complete the process of shaving the rubber pillars and rubber edges inside the main body, which is the core part of the equipment. This part also contains auxiliary facilities such as the rubber crumb collecting trolley and operation panel.

3. Tire-out device: After the tyre is finished shaving, it is kicked out of the shaving body, and after the deceleration of the tire-out device, it finally falls on the line below it, and the whole process is completed. In the case of a specific tire direction, this part of the device can be eliminated.
