Description

Technical Field

[0001] This utility model relates to the technical field of roll material processing equipment, specifically a bending and straightening machine. Background Technology

[0002] The workshop tension straightening equipment is mainly used for stretching and straightening aluminum strips to produce flat aluminum strips. During the production process, the strip surface comes into contact with the tension rollers, causing aluminum dust to adhere to the roller surface. When the aluminum dust accumulates to a certain extent, it will adhere to the surface of the coil, causing the surface quality of the coil to fail to meet the quality requirements. Usually, personnel use manual wiping to wipe the roller surface to ensure that the rollers are clean and meet the production quality requirements. The disadvantage of manual wiping is that it is labor-intensive for workers and can easily cause injuries. Utility Model Content

[0003] The main purpose of this utility model is to provide a bending straightening machine to solve the problems of high labor intensity and easy injury to workers caused by manual cleaning of rollers in the prior art.

[0004] To achieve the above objectives, this utility model provides a tension straightening machine, including a front tension roller group and a rear tension roller group, both of which include multiple tension rollers; one side of the tension roller is in contact with the roll material, and the other side of the tension roller is provided with a spray pipe for spraying cleaning liquid onto the roller surface of the tension roller, and the spray pipe is provided with multiple nozzles.

[0005] Furthermore, the spray pipe is connected to a cleaning fluid pipe, the cleaning fluid pipe is connected to a cleaning fluid tank, and a cleaning fluid pump is connected to the cleaning fluid pipe.

[0006] Furthermore, a carbon dioxide spray pipe is installed above the tension roller, and multiple carbon dioxide nozzles are installed on the carbon dioxide spray pipe.

[0007] Furthermore, the carbon dioxide spray pipe is connected to the outlet of a carbon dioxide storage cylinder via a pipe, and a cylinder head valve is installed at the outlet of the carbon dioxide storage cylinder; a nitrogen starter cylinder is installed on one side of the carbon dioxide storage cylinder, and the outlet of the nitrogen starter cylinder is connected to a cylinder head valve via a pipe; a solenoid valve is installed at the outlet of the nitrogen starter cylinder; a temperature sensor and a smoke sensor electrically connected to the solenoid valve are installed above the tension roller.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3As shown, according to an embodiment of the present invention, a tension straightening machine is provided, including a front tension roller group and a rear tension roller group. Both the front and rear tension roller groups include four rotatable tension rollers 2. Two of the four tension rollers 2 are located on the upper inner side, and the other two are located on the lower outer side. A roll material 3 is wound on the tension rollers 2. One side of the tension roller 2 is in contact with the roll material 3. The other side of the tension roller 2 is provided with a spray pipe 5 for spraying cleaning liquid onto the roll surface of the tension roller 2. The spray pipe 5 is provided with multiple nozzles 501. The spray pipe 5 is located between two tension rollers 2, does not affect the winding and movement of the roll material, and can convert the cleaning liquid into a mist and spray it directly onto the roller surface.

[0018] The spray pipe 5 is connected to the cleaning fluid pipe 6, the cleaning fluid pipe 6 is connected to the cleaning fluid tank 7, and the cleaning fluid pump 4 is connected to the cleaning fluid pipe 6. The cleaning fluid in the cleaning fluid tank 7 is specifically industrial alcohol with a purity of 99% or 40# light white oil.

[0019] A carbon dioxide spray pipe 8 is provided above the tension roller 2, and multiple carbon dioxide nozzles 801 are provided on the carbon dioxide spray pipe 8.

[0020] The cleaning fluid is flammable and is prone to oil mist explosion and fire during spraying. By installing carbon dioxide spray pipes, fires can be extinguished in time and fire accidents can be prevented.

[0021] In some embodiments, the carbon dioxide spray pipe 8 is connected to the outlet of the carbon dioxide storage cylinder 9 via a pipe. The outlet of the carbon dioxide storage cylinder 9 is equipped with a cylinder head valve 901, which can be activated by both pneumatic and manual means. A nitrogen starter cylinder 10 is provided on one side of the carbon dioxide storage cylinder 9. The outlet of the nitrogen starter cylinder 10 is connected to the cylinder head valve 901 via a pipe. A solenoid valve 1001 is provided at the outlet of the nitrogen starter cylinder 10. A temperature sensor 11 and a smoke sensor 12, which are electrically connected to the solenoid valve 1001, are provided above the tension roller 2.

[0022] By setting up smoke detector 11 and temperature detector 12, if the temperature is too high or a large amount of smoke is detected, the solenoid valve 1001 can be opened. The nitrogen in the nitrogen starter cylinder 10 is injected into the cylinder head valve 901. The valve of the cylinder head valve 901 is pneumatically opened, and the gas in the carbon dioxide storage cylinder 9 quickly enters the carbon dioxide spray pipe 8, causing the carbon dioxide spray pipe 8 to spray carbon dioxide to extinguish the fire.

[0023] In some embodiments, an inlet guide roller 13 is provided in front of the front tension roller group, and an unwinder 14 is provided in front of the inlet guide roller 13; an outlet guide roller 15 is provided behind the rear tension roller group, and a winding machine 16 is provided behind the outlet guide roller 15.

[0025] In the above embodiment, the tension roller 2 is in the open state, and the coil 3 moves in the direction of the arrow. The spray pipe 5 sprays cleaning liquid onto the tension roller 2, causing the aluminum ash adhering to the tension roller 2 to fall off. The fallen aluminum ash adheres to the head of the coil 3 or the threading material and is carried away by the head of the coil 3 or the threading material, thus cleaning the tension roller. The threading material is an auxiliary material used to guide the coil 3 smoothly into the straightening machine or continuous production line. The head is the part of the front of the coil 3 that needs to be cut off. Using the threading material or the head to carry away the aluminum ash can prevent the aluminum ash from adhering to the surface of the aluminum coil and affecting the quality of the aluminum coil.

[0026] Before using this embodiment, the tension rollers were manually wiped, which took about 50 minutes to wipe eight tension rollers. The working space was narrow during wiping, and worker misoperation could lead to worker injury during the wiping process. With the tension straightening machine of this embodiment, the tension rollers can be cleaned during the material handling and tape threading process without spending extra time. The cleaning efficiency is high, and there is no need for manual wiping of the tension rollers, thus avoiding the problem of worker injury during the wiping process.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
