Description

Technical Field

[0001] The invention belongs to the technical field of plate and strip finishing treatment, and in particular relates to a high-speed trimming line waste vacuum suction and treatment system. Background Art

[0002] At present, in the thin strip trimming production line, the scrap edge of the strip after being sheared by the disc shear is generally cut off by the scrap shear, or the scrap edge is directly coiled by the curling machine. The speed of the scrap shear and the curling machine is usually not too high, and the speed of the unit is usually below 800m / min.

[0003] In the production process of some thin strip high-speed trimming lines, the scrap strip processing technology of the scrap shear and the curling machine directly coiling can no longer handle the scrap strips of the high-speed shearing of the unit, and cannot meet the needs of high-speed production of thin strips. For example, in the production process of aluminum can materials, the thickness of the aluminum material usually does not exceed 0.27mm, and the thinnest aluminum material thickness can even reach 0.1mm, while the aluminum coil has a large coil diameter (the maximum coil diameter reaches Ø2800mm). The factory has high requirements for the output of this type of can material (for example, a domestic aluminum plant requires an annual output of 120kt / y for can aluminum coils), and the unit speed is high (the maximum unit speed reaches 1500mm / min) to meet market needs. The running speed of the scrap edge shear itself cannot keep up with the high speed of the unit, and there is a synchronization problem between the scrap edge shear and the disc shear. If the running speed of the scrap edge shear is higher than that of the disc shear, the waste edges are easy to be broken; if the running speed of the scrap edge shear is lower than that of the disc shear, the waste edges will accumulate in front of the scrap edge shear, both of which will cause production accidents; the production method of the curling machine directly rolling up the waste edges also cannot meet the requirements of high-speed operation of the unit. When the unit runs at high speed, the high-speed running waste edges will move irregularly and chaotically after encountering air resistance, and accumulate at the outlet of the disc shear, causing production accidents. If the curling machine pulls the waste edges to roll them up, there is also a problem of speed synchronization. If the curling machine pulls the waste edges too fast, the waste edges are easy to be broken; if the curling machine pulls the waste edges too slowly, the waste edges will accumulate at the disc shear, which also causes production accidents.

[0004] Moreover, the process of directly processing waste edges by the edge shears and curling machines will generate a large amount of dust, seriously affecting the workers' production environment, causing dust pollution, and directly threatening the occupational health of the workers.

[0005] Similar problems also exist in the production process of ultra-thin tinplate.

[0006] Therefore, a new high-speed trimming line waste treatment solution is urgently needed to meet the needs of high-speed operation of the unit. Summary of the invention

[0007] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a high-speed trimming line waste vacuum suction and processing system, which is used to deal with the waste problems of the high-speed trimming unit and meet the requirements of high-speed operation of the unit; solve the environmental pollution problems generated in the production process and purify the working environment; and solve the speed synchronization problem between the unit equipment to prevent production accidents caused by waste breakage or accumulation and jamming.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 and Figure 4 As shown, the air supply device 1 is mainly composed of a ventilation fan 1.1, a silencer 1.2, a fan 1.3, a fan room 1.4, a first electric butterfly valve a, a first pressure sensor P, etc. The fan 1.3 is installed in the fan room 1.4, the ventilation fan 1.1 and the silencer 1.2 are installed on the roof of the fan room 1.4, and a bypass pipe is arranged on the main outlet pipe 2 of the fan 1.3, and the bypass pipe is equipped with a first electric butterfly valve a and a silencer 1.2. The ventilation fan 1.1 is used to discharge the heat generated by the fan 1.3 when it is working; the first pressure sensor P is used to detect the pressure of the high-speed airflow on the pipeline, the first electric butterfly valve a is used to adjust the size of the high-speed airflow and pressure on the pipeline, and the silencer 1.2 is used to eliminate or reduce the noise generated by the high-speed airflow at the outlet of each pipeline.

[0021] like Figure 1 and Figure 3 As shown, the main pipeline 2 is connected to the outlet of the fan 1.3. The main pipeline 2 is equipped with a second electric butterfly valve a and a second pressure sensor P. The pipeline 2.1 is a hose connected to the waste edge interface device 4.

[0022] like Figure 2 As shown, the bracket 3 is used to support the main pipeline 2 and the branch pipeline 5.

[0023] like Figure 5 , Figure 6 and Figure 7 As shown, the scrap edge interface device 4 is composed of a third electric butterfly valve a, a pipeline 4.1, a cross ball cage joint 4.2, a movable seat 4.3, a fixed base 4.4, a linear guide 4.5, an encoder 4.6, a ball screw 4.7, a cylinder 4.8, a motor 4.9 and a telescopic tube 4.10. The third electric butterfly valve a is installed on the pipeline 4.1 to adjust the pressure and flow of the high-speed airflow in each branch pipeline, the cross ball cage joint 4.2 is installed on the pipeline 4.1, the telescopic tube 4.10 is installed in the pipeline 4.1, the pipeline 4.1 is installed on the movable seat 4.3, the movable seat 4.3 is installed on the fixed base 4.4 through a linear guide 4.5, the ball screw 4.7 is installed on the fixed base 4.4 and drives the movable seat 4.3 to move, the encoder 4.6 and the motor 4.9 are installed at both ends of the ball screw 4.7, the cylinder 4.8 is installed on the pipeline 4.1 and drives the telescopic tube 4.10 to move. When the width of the strip cut by the disc shear changes, the motor 4.9 drives the ball screw 4.7 to rotate, thereby driving the movable seat 4.3 to make corresponding lateral movements, and at the same time, the encoder 4.6 at the end of the ball screw 4.7 starts counting to ensure that the width of the two pipes 4.1 just meets the requirements of the strip cutting width; at the same time, the cylinder 4.8 drives the telescopic tube 4.10 to move forward, so that the telescopic tube 4.10 reaches the shearing area of ​​the disc shear, and the high-speed airflow forms a vacuum area in the telescopic tube 4.10, sucking in the waste edges cut by the disc shear and the dust generated by the disc shear; when the disc shear is replaced with a blade or repaired, the telescopic tube 4.10 retracts to free up more operating space for the repair of the disc shear.

[0024] like Figure 2 and Figure 3 As shown, one end of the branch pipe 5 is connected to the cross ball cage joint 4.2, and the other end is connected to the scrap edge clamping device 6.

[0025] like Figure 8 , Fig. 9 and Fig.10As shown, the scrap edge clamping device 6 comprises a servo motor 6.1, a scrap edge clamping frame 6.2, a cylinder 6.3, a fixed roller 6.4, and a swing roller 6.5. The servo motor 6.1, the cylinder 6.3, the fixed roller 6.4, and the swing roller 6.5 are all installed on the scrap edge clamping frame 6.2. The servo motor 6.1 is connected to the shaft end of the fixed roller 6.4 and drives the fixed roller 6.4 to rotate, and the cylinder 6.3 drives the swing roller 6.5 to swing. When the waste tape head leads the tape, the cylinder 6.3 drives the swing roller 6.5 to open, and the waste tape head enters between the fixed roller 6.4 and the swing roller 6.5, and the cylinder 6.3 drives the swing roller 6.5 to swing, and the fixed roller 6.4 and the swing roller 6.5 clamp the waste tape head together, and the servo motor 6.1 drives the fixed roller 6.4 to rotate, and the waste tape head is pulled into the crimping machine 7. The linear speed of the fixed roller 6.4 driven by the servo motor 6.1 is slightly higher than the speed of the unit, so that the scrap edge is in a state of small tension. Under the dual action of the high-speed airflow and the pinch roller (the pinch roller formed by the fixed roller 6.4 and the swing roller 6.5), the scrap edge will not accumulate in the pipeline; when the scrap edge is accidentally broken, the scrap edge enters the pinch roller (the pinch roller formed by the fixed roller 6.4 and the swing roller 6.5) under the sweep of the high-speed airflow, and then enters the hemming machine, and the scrap edge will not accumulate in the pipeline. Therefore, the joint action of the high-speed airflow and the pinch roller (the pinch roller formed by the fixed roller 6.4 and the swing roller 6.5) solves the problem of scrap edge treatment of the thin strip high-speed trimming unit, so that the unit can produce at high speed; at the same time, it solves the speed synchronization problems such as scrap tape breakage, scrap tape accumulation and jamming; at the same time, the high-speed airflow brings the dust generated by the shearing of the disc shear into the closed chamber 8 through the pipeline, and finally discharges the dust through the dust removal equipment 9.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the scrap edge clamping device 6 is installed on the fixed frame 7.4 of the crimping machine.

[0027] like Fig.11 , Fig.12 and Fig.13As shown, the hemming machine 7 comprises a transmission reel 7.1, a transmission base 7.2, a hydraulic cylinder 7.3, a fixed frame 7.4 of the hemming machine, a hydraulic cylinder 7.5, a hydraulic cylinder 7.6, a baffle 7.7, and a pressure roller 7.8. The transmission reel 7.1 is mounted on the transmission base 7.2 and driven by a motor to rotate; the hydraulic cylinder 7.3 is mounted on the transmission base 7.2, and the hydraulic cylinder 7.3 drives the transmission reel 7.1 to move transversely; the hydraulic cylinder 7.5, the hydraulic cylinder 7.6, the baffle 7.7 and the pressure roller 7.8 are all mounted on the fixed frame 7.4 of the hemming machine; the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move; and the hydraulic cylinder 7.6 drives the baffle 7.7 to move. When the waste tape is threaded and led, the hydraulic cylinder 7.3 drives the transmission reel 7.1 to enter the fixed frame 7.4 of the crimping machine, the hydraulic cylinder 7.6 drives the baffle 7.7 to close, the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move and open, the motor drives the transmission reel 7.1 to rotate, and the waste tape head begins to wind on the transmission reel 7.1. At this time, the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move and press the waste tape, making the waste tape winding more dense. When the detection instrument detects that the waste edge is rolled to a certain extent, at this time, the hydraulic cylinder 7.5 drives the pressure roller 7.8 to open, the hydraulic cylinder 7.6 drives the baffle 7.7 to open, and the hydraulic cylinder 7.3 drives the transmission reel 7.1 to withdraw from the working position, and the waste roll will roll to the designated collection position.

[0028] The fixed frame 7.4 of the crimping machine is installed in the closed chamber 8 of the crimping machine.

[0029] like Figure 1 and Figure 2 As shown, the dust removal device 9 comprises a muffler 9.1, a fan 9.2, a dust collector 9.3, and a valve 9.4. The dust removal device 9 sucks away the dust generated by shearing and the dust generated by scrap edge coiling in the closed chamber 8 through a pipeline.

[0030] When the thickness of the produced strip changes, the opening and closing degree of the butterfly valve a on the bypass pipe on the main pipe can be adjusted to control the pressure and flow of the high-speed airflow on the main pipe to meet the production needs of different strip thicknesses.

[0031] When the widths of the waste edges on both sides cut by the disc shear are inconsistent, the opening and closing degrees of the butterfly valves a on the two pipes can be adjusted respectively, so that the opening degree of the butterfly valve of the branch pipe on the wide waste edge side is greater than the opening degree of the branch pipe on the narrow waste edge side, and the high-speed airflow flow rate of the branch pipe on the wide waste edge side is greater than the high-speed airflow flow rate of the branch pipe on the narrow waste edge side, thereby adjusting the suction force of the two pipes to meet production needs.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
