Description

Technical Field

[0001] This utility model relates to the technical field of tire production, and in particular to a tread rubber weighing and feeding device. Background Technology

[0002] During the extrusion production of aircraft tire treads, the rubber compound is first added to the extruder. Before entering the extruder, the tread rubber compound (usually a hot-refined rubber block) needs to be weighed in real time by a weighing module (such as an electronic scale or weighing sensor) to ensure that the weight error of each section of tread rubber is controlled within a very small range, and to avoid problems such as excessive or insufficient tread size and uneven thickness caused by too much or too little rubber compound. When weighing rubber compound, the holding device is first placed on an electronic scale. Then, the rubber compound is fed into the holding device through a feeding device, and the weight of the rubber compound in the holding device is weighed by the electronic scale until the weight of the rubber compound reaches the specified value. The holding device is then transferred to the top of the extruder, and the rubber compound in the holding device is poured into the extruder. Existing feeding devices, such as the utility model patent with patent application number 202222022326.7, disclose a gypsum powder production feeding device, which mainly uses a screw conveyor for feeding. However, when applied to feeding rubber compound, it has the following problems: although the feeding is stable, the feeding speed is slow, and it is inconvenient to feed large pieces of rubber compound. It is inconvenient to use and not suitable for feeding tread rubber compound. Therefore, a weighing and feeding device with fast feeding speed and convenient use is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a tire tread rubber weighing and feeding device that uses a belt conveyor to quickly transport large pieces of material to a holding mechanism, so that the rubber material in the holding mechanism quickly reaches a specified weight. Then, a screw conveyor smoothly transports small pieces of material to the holding mechanism, so that the rubber material in the holding mechanism reaches a specified value. This device ensures both feeding speed and feeding accuracy, and facilitates the rapid transport of large pieces of rubber material. It is easy to use and highly practical.

[0004] This utility model discloses a tire tread rubber weighing and feeding device, including a base plate; it also includes a belt conveyor, a conveyor belt, a weighing mechanism, a holding mechanism, and a screw conveyor mechanism. The holding mechanism is mounted on the weighing mechanism, the screw conveyor mechanism is mounted on the base plate with its output end above the holding mechanism, and the belt conveyor is mounted on the base plate with a conveyor belt. The output end of the belt conveyor is also above the holding mechanism. When feeding the material to the production unit, large pieces of rubber are placed on the conveyor belt for transport, while several pieces are simultaneously placed into the screw conveyor mechanism to be crushed into smaller pieces. The conveyor belt then transports the larger pieces to the holding mechanism. The operator calculates the weight of the rubber in the holding mechanism using the weighing mechanism. Once the weight of the rubber is close to a predetermined value, the belt conveyor is shut off. The conveyor belt stops feeding large pieces of material into the holding mechanism. Then, the screw conveyor is activated to smoothly transport the crushed small pieces of rubber into the holding mechanism until the rubber in the holding mechanism reaches the specified weight. Afterward, an external crane or other equipment is used to move the holding mechanism to the vicinity of the extruder, and then the rubber in the holding mechanism is transferred to the extruder. This system uses a belt conveyor to quickly transport large pieces of material into the holding mechanism, rapidly bringing the rubber in the holding mechanism to near the specified weight. Then, a screw conveyor smoothly transports small pieces of material into the holding mechanism, ensuring the rubber in the holding mechanism reaches the specified weight. This system guarantees both feeding speed and feeding accuracy, and facilitates the rapid transport of large pieces of rubber. It is convenient to use and highly practical.

The clamp can be a four-jaw chuck or a flat-jaw vise, and the holding mechanism is clamped and fixed by the clamp. When material is put into the holding mechanism, the electronic scale weighs the holding mechanism to estimate the weight of the material in the holding mechanism. After the material is put into the holding mechanism, the linear module causes the sliding plate to move the electronic scale forward, and the electronic scale moves the holding mechanism forward to a position that is easy for the operator to operate, thus moving the operator to the holding mechanism.

When the rubber in the holding box is about to reach a specified value, the belt conveyor is turned off, and then the motor A is turned on. The motor A drives the rotating shaft to rotate, and then the spiral blade rotates, so that the small pieces of rubber are conveyed by the spiral blade to the holding box through the conveying pipe, ensuring the feeding accuracy.

[0008] Preferably, the crushing mechanism includes an arc-shaped plate, a motor B, and a crushing shaft.

[0021] Example 1

[0022] like Figures 1 to 6The tire tread rubber weighing and feeding device of this utility model includes a base plate 1, a belt conveyor 2, a conveyor belt 3, a weighing mechanism, a holding mechanism, and a screw conveyor mechanism.

The belt conveyor 2 is installed on the base plate 1, and the conveyor belt 3 is installed on the belt conveyor 2. The output end of the belt conveyor 2 is located above the holding mechanism. When feeding the production mechanism, large pieces of rubber are placed on the conveyor belt 3 for conveying, while several pieces of rubber are simultaneously placed into the screw conveyor mechanism to be crushed into smaller pieces. Then, the conveyor belt 3 transports the large pieces to the holding mechanism. The operator calculates the weight of the rubber in the holding mechanism using the weighing mechanism. After the weight of the rubber is close to the specified value, the device is ready to be used. Turn off belt conveyor 2 to stop feeding large pieces of material into the holding mechanism. Then, turn on the screw conveyor to smoothly transport the crushed small pieces of rubber into the holding mechanism until the rubber in the holding mechanism reaches the specified value. After that, use an external crane or other equipment to move the holding mechanism to the vicinity of the extruder, and then transfer the rubber in the holding mechanism to the extruder. This method uses belt conveyor to quickly transport large pieces of material into the holding mechanism, so that the rubber in the holding mechanism quickly reaches the specified weight. Then, the screw conveyor smoothly transports small pieces of material into the holding mechanism, so that the rubber in the holding mechanism reaches the specified value. This method ensures both feeding speed and feeding accuracy, and facilitates the rapid transport of large pieces of rubber. It is convenient to use and highly practical.

[0023] like Figure 1 and Figure 3 The weighing mechanism includes a linear module 4, a sliding plate 5, and an electronic scale 6.

The clamp can be a four-jaw chuck or a flat-jaw vise. The holding mechanism is clamped and fixed by the clamp. When material is put into the holding mechanism, the electronic scale 6 weighs the holding mechanism to estimate the weight of the material in the holding mechanism. After the material is put into the holding mechanism, the linear module 4 causes the sliding plate 5 to move the electronic scale 6 forward. The electronic scale 6 moves the holding mechanism forward to a position that is easy for the operator to operate, allowing the operator to move the holding mechanism.

The motor A13 is fixedly installed on the crushing box 11, and the rotating shaft 14 is rotatably installed on the crushing box 11. A spiral blade is installed on the rotating shaft 14. The spiral blade is located in the lower part of the cavity of the crushing box 11 and in the conveying pipe 12. The power output end of the motor A13 is connected to the left end of the rotating shaft 14. Several large pieces of tire tread rubber are put into the crushing box 11, and then the rubber is crushed into small pieces by the crushing mechanism. When the rubber in the holding box 7 is about to reach the specified value, the belt conveyor 2 is turned off, and then the motor A13 is turned on. The motor A13 drives the rotating shaft 14 to rotate, and then the spiral blade rotates, so that the small pieces of rubber are conveyed by the spiral blade through the conveying pipe 12 to the holding box 7, ensuring the accuracy of feeding.

[0026] like Figure 1 and Figure 5 The crushing mechanism includes an arc-shaped plate 15, a motor B16, and a crushing shaft 17.

Multiple crushing blades are provided on the crushing shaft 17, and the multiple crushing blades are all located above the arc-shaped plate 15. After the rubber material is added into the cavity of the crushing box 11, the rubber material falls onto the arc-shaped plate 15. Then, the motor B16 is turned on, and the motor B16 causes the crushing shaft 17 to rotate, crushing the rubber material. The crushed rubber material falls into the lower part of the cavity of the crushing box 11 through the through holes on the arc-shaped plate 15.

The multiple springs 18 are fixedly installed at the lower end of the chamber of the holding box 7, and the pad 19 is fixedly installed at the upper end of the multiple springs 18. When the belt conveyor 2 and the conveyor belt 3 convey large pieces of rubber into the holding box 7, the rubber falls onto the upper end of the pad 19 in the holding box 7. Then, the multiple springs 18 cushion the pad 19, reducing the instantaneous impact force on the holding box 7 and reducing the impact on the holding box 7.

[0030] like Figure 5 Multiple scrapers are also provided on the crushing shaft 17, and the multiple scrapers are intersected with the multiple through holes of the arc plate 15 in the horizontal direction. With the above arrangement, the crushing shaft 17 rotates and drives the scrapers to rotate.
