Description

Technical Field

[0001] This utility model relates to the field of steel belt conveyor equipment, and in particular to a negative pressure adsorption traction device for steel belt conveying. Background Technology

[0002] In the initial stage of steel strip processing, the steel strip needs to be unwound and one end of the steel strip needs to be transported to the other end of the equipment to facilitate the processing or rewinding of the steel strip.

[0003] In the current technology, in the initial stage of steel belt conveying, manual traction is usually used at one end of the steel belt. This operation is time-consuming and labor-intensive. Moreover, the steel belt is heavy and requires multiple operators to cooperate, resulting in low work efficiency. There are also certain safety hazards during the traction process, which need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure adsorption traction device for steel belt conveying, which automatically tractions one end of the steel belt, thereby improving work efficiency and safety.

[0005] To achieve this objective, the present invention adopts the following technical solution: A negative pressure adsorption traction device for steel belt conveying includes: a frame, a negative pressure box, and a conveyor frame. The conveyor frame is rotatably arranged in the frame, and a conveyor belt is arranged on the conveyor frame. The conveyor belt is located below or above the conveying path of the steel belt. The negative pressure box is arranged in the conveyor frame and is located inside the conveyor belt. The side surface of the negative pressure box facing the steel belt is in sliding contact with the inner wall of the conveyor belt and is provided with first adsorption holes at intervals. The conveyor belt is provided with second adsorption holes at intervals corresponding to the first adsorption holes.

[0006] One end of the conveyor frame is provided with a hinge that connects to the machine frame.

[0007] The conveyor frame has a first pin seat on one side, and the frame has a second pin seat located above or below the first pin seat. A cylinder or hydraulic cylinder is provided between the first pin seat and the second pin seat.

[0008] The frame is equipped with a vacuum pump, and a pipe joint is provided on one side of the negative pressure box. An air pipe is provided between the pipe joint and the air inlet of the vacuum pump.

[0009] The trachea is made of corrugated tubing.

[0010] The frame is equipped with a steel strip unwinding frame, which is located in front of one end of the conveyor frame.

[0011] The first adsorption hole adopts a waist hole structure that extends along the length of the conveyor belt.

[0012] The beneficial effects of this utility model are as follows: A negative pressure adsorption traction device for steel belt conveying generates negative pressure adsorption force on the conveyor belt through the cooperation of the first adsorption hole and the second adsorption hole, adsorbing one end surface of the steel belt. It has high stability and reduces the probability of the steel belt falling off. Through the operation of the conveyor belt, the end of the steel belt is pulled and transported to the other end of the equipment. Then the conveyor frame flips, so that the conveyor belt is separated from the steel belt without affecting the subsequent conveying of the steel belt. It reduces friction and energy consumption, has a high degree of automation, and improves production efficiency and operational safety. Attached Figure Description

[0014] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 The negative pressure adsorption traction device for steel belt conveying shown is used for traction at the end of the steel belt 4 during the conveying process. It includes: frame 1, negative pressure box 3 and conveyor frame 2. The conveyor frame 2 is rotatably arranged in the frame 1. One end of the conveyor frame 2 is provided with a hinge 10 connected to the frame 1, and the hinge 10 supports the rotatability of the conveyor frame 2.

[0016] like Figure 2 As shown, a first pin seat 12 is provided on one side of the conveyor frame 2, and a second pin seat 8 is provided in the frame 1, located above or below the first pin seat 12. A cylinder 7 or a hydraulic cylinder is provided between the first pin seat 12 and the second pin seat 8. The conveyor frame 2 is flipped and its angle is changed by the extension and retraction of the cylinder 7 or the hydraulic cylinder. The extension and retraction of the cylinder 7 or the hydraulic cylinder can be controlled by a solenoid valve, which is simple to operate and improves safety.

[0017] A conveyor belt 11 is provided on the conveyor frame 2. The conveyor belt 11 is located below or above the conveying path of the steel belt 4. The negative pressure box 3 is provided in the conveyor frame 2 and is located inside the conveyor belt 11. A vacuum pump 5 is provided in the frame 1. A pipe joint 9 is provided on one side of the negative pressure box 3. An air pipe 6 is provided between the pipe joint 9 and the air inlet of the vacuum pump 5 to evacuate the negative pressure box 3 and form a negative pressure cavity in the negative pressure box 3.

[0018] In this embodiment, the air pipe 6 is a corrugated pipe, which can be bent to adapt to the angle changes of the conveyor frame 2. The side surface of the negative pressure box 3 facing the steel belt slides in contact with the inner wall of the conveyor belt 11 and is provided with first adsorption holes at intervals. The conveyor belt 11 is provided with second adsorption holes at intervals corresponding to the first adsorption holes. In this embodiment, the first adsorption holes adopt a waist hole structure extending along the length direction of the conveyor belt 11.

[0019] A steel strip unwinding frame 13 is provided in the frame 1. The steel strip unwinding frame 13 is located in front of one end of the conveyor frame 2. The steel strip 4 is unwound through the steel strip unwinding frame 13. In the initial stage of conveying, the angle of the conveyor frame 2 is adjusted, such as... Figure 1 As shown, the surface of the conveyor belt 11 contacts and adheres to one end of the steel belt 4, resulting in high stability and reducing the probability of the steel belt 4 falling off. Through the operation of the conveyor belt 11, the end of the steel belt 4 is pulled and transported to the other end of the equipment.

[0020] After the end of the steel belt 4 is pulled during the conveying process, the conveyor frame 2 is driven to flip by the cylinder 7, so that the conveyor belt 11 is separated from the steel belt 4. This does not affect the subsequent conveying of the steel belt 4, reduces friction and energy consumption, has a high degree of automation, and improves production efficiency.
