Description

Technical Field

[0001] The invention relates to the technical field of grinding, and in particular to a steel plate processing device for light steel assembled houses. Background Art

[0002] Lightweight steel prefabricated houses use high-quality steel plates as one of the main building materials. These steel plates are carefully selected and specially treated to ensure their strength, corrosion resistance and durability. Steel plates play a vital role in the construction of lightweight steel prefabricated houses. They are used as supporting materials for key structures such as walls, roofs and floors. These steel plates not only have excellent load-bearing capacity and can withstand various natural disasters and adverse climatic conditions, but also have good heat and sound insulation properties, providing residents with a comfortable and safe living environment.

[0003] At present, a Chinese patent with the announcement number CN209364269U discloses a steel plate processing device for light steel prefabricated houses, including a conveying mechanism and a polishing sheet arranged beside the conveying mechanism, wherein the polishing sheet is driven to rotate by a rotary motor 1. During grinding, the steel plate can be placed on the conveying mechanism, and then driven by the conveying mechanism, the steel plate abuts against the polishing sheet in a moving posture to achieve side grinding.

[0004] However, in order to achieve the best effect when grinding the steel plate once, multiple grinding mechanisms such as polishing sheets are often arranged in the moving direction of the steel plate to ensure the grinding effect by increasing the number of grinding points. However, when grinding different batches of steel plates, since the sides of different steel plates need to be polished to different degrees, it is easy for the previous grinding mechanism to produce sufficient grinding effect, but the subsequent grinding mechanism still grinds redundantly. This may cause excessive wear of the grinding mechanism on the one hand, and excessive grinding of the steel plate on the other. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a steel plate processing device for light steel assembled houses.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A steel plate processing device for light steel prefabricated houses comprises a frame, a conveying mechanism is arranged on the frame, a grinding mechanism is also arranged on the frame next to the conveying mechanism, the grinding mechanism comprises at least two grinding pieces arranged in sequence along the conveying direction of the conveying mechanism, the grinding pieces are adapted to be able to exert different magnitudes of grinding forces on the side surfaces of the steel plates, a detection piece is arranged between adjacent grinding pieces, the detection piece can detect the roughness of the side surfaces of the steel plates, and control the subsequent grinding pieces to perform a corresponding magnitude of grinding forces according to the magnitude of the roughness.

[0008] Preferably, the detection component includes a visual module capable of photographing and detecting the side of the steel plate.

[0009] Preferably, the grinding surface of the grinding piece abuts against the side surface of the steel plate through biasing, so that the grinding piece has a zero grinding force mode without contacting the steel plate.

[0010] Preferably, the grinding piece is biased and moved toward one side of the steel plate through a linear ejection mechanism.

[0011] Preferably, the grinding member comprises a grinding belt, and the grinding belt is biased toward one side of the steel plate through a linear ejection mechanism.

[0012] Preferably, the grinding member changes the grinding force by adjusting the rotation speed.

[0013] Preferably, the detection part includes a rotatable friction wheel, which is adapted to rotate under the rubbing of a steel plate with a threshold roughness. The grinding part also includes a sliding rheostat, a cable is connected between the sliding plate of the sliding rheostat and the friction wheel, and a reset spring is connected to the sliding plate of the sliding rheostat.

[0014] Preferably, the detection member includes a rotatable friction wheel, a cam is also provided on the rotating shaft of the friction wheel, a connecting plate is provided on the ejection end of the linear ejection mechanism, the connecting plate is opposite to the cam, and a torsion spring is also connected to the friction wheel. The friction wheel is adapted to rotate under the rubbing of a steel plate with a threshold roughness, thereby driving the cam to gradually push out the connecting plate.

[0015] Preferably, the outer edge of the friction wheel is adapted to have different roughnesses in the circumferential direction, and when the friction wheel is in a natural state, the roughness of the outer edge of the friction wheel gradually decreases in the direction away from the steel plate.

[0016] Preferably, a storage tube is provided on the frame between the friction wheel and the preceding grinding piece, and a grinding aid is provided in the storage tube, one end of the storage tube is open to the grinding surface of the preceding grinding piece, and the other end of the storage tube is slidably adapted with a push rod, and an abutment plate is also provided on the outer edge of the friction wheel, and the abutment plate can abut and push the push rod to push out the grinding aid in the storage tube.

[0017] The beneficial effects of the present invention are:

[0018] 1. The grinding condition of the side of the steel plate is detected by the detection part. If grinding is still required, the subsequent grinding parts are controlled to increase the grinding force on the side of the steel plate to achieve the expected grinding effect; if grinding is not required, the subsequent grinding parts are controlled to maintain or reduce the grinding force on the side of the steel plate. Compared with the prior art, the present invention can effectively prevent redundant grinding of the steel plate through the cooperation of the detection part and the grinding part, so that the steel plate and the grinding part are not prone to over-grinding.

[0019] 2. The grinding force of the grinding piece is adjusted by bias voltage, so that the subsequent grinding piece does not need to contact the steel plate when the steel plate grinding effect is sufficient, and the life of the grinding piece is longer.

[0020] 3. The roughness of the side of the steel plate can be detected by the abutment rotation of the friction wheel and the steel plate. At the same time, the rotation of the friction wheel can also realize the real-time adjustment of the grinding force of the grinding workpiece through the sliding rheostat or cam.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, a steel plate processing device for light steel prefabricated houses includes a frame 1, a conveying mechanism 2 is arranged on the frame 1, and a grinding mechanism 3 is arranged on the frame 1 next to the conveying mechanism 2. Similar to the prior art, the conveying mechanism 2 can be a transmission belt or an ejection device (not shown in the figure), and the side of the steel plate 20 passes through the grinding mechanism 3 and is polished by ejecting the steel plate 20. The grinding mechanism 3 can specifically include at least two grinding pieces 4 arranged in sequence along the conveying direction of the conveying mechanism 2, and the present disclosure preferably shows an embodiment in which there are two grinding pieces 4.

[0030] See also Figure 1 , a detection piece 5 is arranged between adjacent grinding pieces 4, and the detection piece 5 can detect the roughness of the side of the steel plate 20 after being ground by the previous grinding piece 4, and each grinding piece 4 is adapted to act on the side of the steel plate 20 with different grinding forces. It can be understood that when the grinding effect of the previous grinding piece 4 on the steel plate 20 is not good, the roughness of the side of the steel plate 20 is still higher than the threshold, and the detection piece 5 will monitor the abnormality and control the subsequent grinding piece 4 to perform the corresponding grinding force according to the roughness. Therefore, redundant grinding of the steel plate 20 can be effectively prevented, and the steel plate 20 and the grinding piece 4 are not prone to over-grinding.

[0031] In a specific example, the grinding member 4 can be a circumferentially rotating grinding belt 8 or a continuously rotating grinding wheel. The detection member 5 can preferably be a visual module 6 capable of photographing and detecting the side of the steel plate 20. For example, the visual module 6 can be composed of a camera and a controller. The camera can photograph the steel plate 20 after being polished by the previous grinding member 4. Depending on the polishing effect, the side of the steel plate 20 will present different glosses. Then the controller can compare the real-time image taken by the camera with the side image of the steel plate 20 with the expected roughness, and then determine whether the side of the steel plate 20 has been polished to have a sufficient polishing effect.

[0032] For example, when the controller determines that the grinding effect of the steel plate 20 is not good, the controller can be used to control the grinding member 4 to increase the rotation speed. Preferably, the grinding member 4 can be controlled to increase or decrease the corresponding rotation speed according to the color difference between the real-time image of the camera and the side image of the steel plate 20 with expected roughness, so as to achieve dynamic adjustment of the grinding force of the subsequent grinding member 4. Among them, the controller is a prior art. In the field of image recognition, it is very common to compare the captured image with the comparison image, finally obtain the result and control other execution part actions according to the result.

[0033] In other embodiments, the grinding piece 4 can be biased and moved toward the side of the steel plate 20 as a whole through the linear ejection mechanism 7. For example, the grinding piece 4 in the form of a grinding wheel can be pushed toward the side of the steel plate 20 as a whole through a cylinder or an oil cylinder, and the grinding force can be adjusted through different abutment forces between the grinding wheel and the side of the steel plate 20. Alternatively, on the basis that the grinding piece 4 is in the form of an abrasive belt 8, the grinding force can be adjusted by biasing the abrasive belt 8 toward the side of the steel plate 20 through the linear ejection mechanism 7.

[0034] Therefore, when the controller determines that the grinding effect of the steel plate 20 is not good, the controller can control the linear ejection mechanism 7 to eject different strokes to adjust the grinding force. Compared with the method of adjusting the grinding force by changing the rotation speed, in this embodiment, the grinding surface of the grinding piece 4 can not contact the steel plate 20 when the grinding effect of the steel plate 20 is sufficient, that is, the grinding piece 4 has a zero grinding force mode without contacting the steel plate 20, which will minimize the meaningless wear of the grinding surface of the subsequent grinding piece 4 and increase the service life of the grinding piece 4.

[0035] It can be understood that in the above two embodiments, the dynamic adjustment of the grinding force of the grinding piece 4 only depends on the electrical control of the detection piece 5, the grinding piece 4 or the linear ejection mechanism 7, which not only increases the system control complexity of the present disclosure, but also reduces the reliability of the use of the present disclosure.

[0036] As another solution, the detection member 5 is preferably a friction wheel 9 that is arranged to rotate, and the friction wheel 9 is adapted to be able to rotate under the rubbing of the steel plate 20 with a threshold roughness. That is, the outer edge roughness of the friction wheel 9 is creatively designed, so that when the steel plate 20 is not polished as expected by the preceding polishing member 4, since the roughness of the side surface of the steel plate 20 is at the threshold that can rub the friction wheel 9, the friction wheel 9 will rotate as expected, thereby achieving the monitoring purpose.

[0037] See also Figure 3 , Figure 4 On the basis that the grinding member 4 adjusts the grinding force by changing the rotation speed, the grinding member 4 further includes a sliding rheostat 10, and a cable 12 is connected between the sliding plate 11 of the sliding rheostat 10 and the friction wheel 9. In addition, a reset spring 13 is also connected to the sliding plate 11 of the sliding rheostat 10.

[0038] When the steel plate 20 does not get the expected grinding of the previous grinding piece 4, the steel plate 20 will rub the friction wheel 9 to rotate, and the cable 12 will gradually wrap around the friction wheel 9 and pull the slide 11 to slide, and then the motor of the grinding piece 4 will change the current to adjust the speed. For example, the current increases, the speed of the grinding piece 4 increases, and the steel plate 20 is further polished; and after the steel plate 20 gets the expected grinding of the previous grinding piece 4, the friction between the friction wheel 9 and the steel plate 20 decreases, so the reset spring 13 can pull the slide 11 back to the initial position, and the speed of the grinding piece 4 is reduced again, which is not easy to cause excessive wear.

[0039] See also Figure 4 , Figure 5 On the basis of adjusting the grinding force by the grinding piece 4 abutting against the side of the steel plate 20 to different degrees through bias pressure, the rotating shaft of the friction wheel 9 can be equipped with a cam 14, and the linear ejection mechanism 7 can cancel the power source and be provided with a connecting plate 15 on its ejection end, and the connecting plate 15 extends to be opposite to the cam 14. In addition, a torsion spring 16 is also provided on the friction wheel 9.

[0040] When the steel plate 20 does not receive the expected grinding of the preceding grinding piece 4, the steel plate 20 will rub the friction wheel 9 to rotate. At this time, the cam 14 will gradually push out the connecting plate 15 and make the grinding surface of the grinding piece 4 further press against the steel plate 20, thereby realizing secondary grinding of the steel plate 20. After the steel plate 20 receives the expected grinding of the preceding grinding piece 4, the friction between the friction wheel 9 and the steel plate 20 is reduced. Thus, the torsion spring 16 can drive the friction wheel 9 to reverse and reset to its initial state, and the pressing force between the grinding surface and the steel plate 20 is reduced, making excessive wear less likely to occur.

[0041] For example, a spring may be connected to the ejection end of the linear ejection structure. When the friction wheel 9 is reversed and reset to the initial state, the ejection end of the linear ejection structure may also be reset to the initial position under the action of elastic force, so that the polished surface is not easily contacted with the steel plate 20.

[0042] In a preferred example, the return spring 13 on the slide 11 and the torsion spring 16 on the friction wheel 9 can be provided with a damping structure, so that the grinding force of the subsequent grinding piece 4 can be delayed and reduced, so that the side of the steel plate 20 can be fully ground. In addition, it is also preferred that the outer edge roughness of the friction wheel 9 has different roughness in the circumferential direction. For example, from the description when the friction wheel 9 is in a natural state (that is, when the return spring 13 and the torsion spring 16 are in a natural state), the outer edge roughness of the friction wheel 9 gradually decreases in the direction away from the steel plate 20.

[0043] For the sake of convenience, the following will define two situations in which the steel plate 20 may have a first roughness and a second roughness after being polished by the preceding polishing piece 4, and the second roughness is greater than the first roughness. The present disclosure may exemplarily have the following usage process:

[0044] When the steel plate 20 passes through the friction wheel 9 with the first roughness, the steel plate 20 rubs the friction wheel 9 to deflect at a first angle. At this time, since the friction coefficient of the contact surface between the friction wheel 9 and the steel plate 20 gradually decreases, the friction wheel 9 will slip at the first deflection angle, and then through the cooperation of the sliding rheostat 10 or the cam 14, the subsequent grinding part 4 will perform secondary grinding on the steel plate 20 with the first grinding force.

[0045] When the steel plate 20 passes through the friction wheel 9 with the second roughness, the steel plate 20 rubs the friction wheel 9 to deflect at a second angle. At this time, since the second roughness is greater than the first roughness, the steel plate 20 will rub the friction wheel 9 to deflect greater than the first angle before slipping, that is, the second angle is greater than the first angle. Subsequently, through the cooperation of the sliding rheostat 10 or the cam 14, the subsequent grinding part 4 will perform a second grinding on the steel plate 20 with a second grinding force greater than the first grinding force.

[0046] The present disclosure can achieve secondary grinding of the steel plate 20 with adaptive grinding force by uniquely selecting the outer edge roughness of the friction wheel 9 .

[0047] See also Figure 6 A storage tube 17 is further provided on the frame 1 between the friction wheel 9 and the preceding grinding piece 4, and a grinding aid such as abrasive paste or lubricant is stored in the storage tube 17. More specifically, the end of the storage tube 17 facing the grinding surface of the preceding grinding piece 4 is open, and the other end is slidably fitted with a push rod 18, and an abutment sheet 19 is provided on the outer edge of the friction wheel 9.

[0048] When the steel plate 20 after being polished by the preceding polishing piece 4 still has excessive roughness, the steel plate 20 will rub the friction wheel 9 to the maximum extent to cause deflection. At this time, it can be determined that the preceding polishing piece 4 needs to be supplemented with a polishing aid for auxiliary polishing. Then the abutment sheet 19 can synchronously push the push rod 18 to extrude and coat the polishing aid in the storage tube 17 onto the polishing surface of the preceding polishing piece 4.

[0049] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
